       The Form 8-A registration statement dated July 3, 1986 filed by PSA, Inc.
(now called PS Group, Inc.) (the "Company") is hereby amended as follows.

 
Item 1.    Description of Registrant's Securities to be Registered
                                        
       The Company has entered into an Agreement and Plan of Reorganization
dated as of January 30, 1996, pursuant to which the Company will, if shareholder
approval is obtained and certain other conditions are satisfied, undergo a
holding company reorganization transaction (the "Reorganization") pursuant to
which the Company will become a wholly-owned subsidiary of a newly-formed
holding company which is currently a subsidiary of the Company, PS Group
Holdings, Inc., a Delaware corporation ("Holdings"), and shareholders of the
Company will receive shares of Holdings in exchange for their shares in the
Company. The sole purpose of the Reorganization is to help preserve the
Company's substantial tax benefits (in the form of net operating loss
carryforwards, investment tax credit carryforwards and other tax benefits) by
implementing transfer restrictions applicable to the shares of Holdings in the
certificate of incorporation of Holdings that are intended to help decrease the
risk of an "ownership change" for federal tax purposes which could have adverse
tax consequences to the Company.

       In connection with the approval of the Reorganization, the Board of
Directors of the Company approved an amendment to the Rights Agreement dated as
of June 30, 1986, between the Company and Chemical Bank (as successor Rights
Agent to Bank of America, N.T. & S.A., the "Rights Agent") (the "Fifth
Amendment"). The Fifth Amendment adds a new Section 33, which exempts the
Reorganization from the operation of the Rights Agreement. An Amended and
Restated Rights Agreement between the Company and Chemical Bank, cumulatively
reflecting such Fifth Amendment plus the amendments previously made on December
6, 1986, September 15, 1988, September 16, 1990 and December 14, 1990, is
incorporated by reference and attached hereto as Exhibit 4.1.

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

     Agreement, dated as of June 30, 1986, between PS Group, Inc. (formerly PSA,
Inc.), a Delaware corporation (the "Company"), and Chemical Bank (as successor
Rights Agent to Bank of America, N.T. & S.A., the "Rights Agent"), as amended on
December 6, 1986, September 15, 1988, September 16, 1990, December 14, 1990 and
January 31, 1996 and hereby restated to reflect cumulatively such amendments.

     The Board of Directors of the Company has authorized and declared a
dividend of one preferred share purchase right (a "Right") for each Common Share
(as hereinafter defined) of the Company outstanding on July 10, 1986, each Right
representing the right to purchase one one-hundredth of a share of Series D
Junior Participating Preferred Stock, par value $1.00 per share, of the Company
having the rights and preferences set forth in the form of Certificate of
Designations attached hereto as Exhibit A, 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 July 10, 1986 and the earliest of the Distribution Date, the
Redemption Date and the Final Expiration Date (as such terms are hereinafter
defined).

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

                                       2
<PAGE>
 
     Section 1.  Certain Definitions.  For purposes of this Agreement, the
                 -------------------                                      
following terms have the meanings indicated:
          (a) "Acquiring Person" shall mean any Person (as such term is
     hereinafter defined) who or which, together with all Affiliates and
     Associates (as such terms are hereinafter defined) of such Person, shall be
     the Beneficial Owner (as such term is hereinafter defined) of 20% or more
     of the Common Shares then outstanding, but shall not include the Company,
     any Subsidiary (as such term is hereinafter defined) of the Company or any
     employee benefit plan of the Company or any Subsidiary of the Company, or
     any entity holding Common Shares for or pursuant to the terms of any such
     plan.  The term "Acquiring Person" shall not mean Warren Buffett or
     Berkshire Hathaway Inc. ("Berkshire") or their respective Affiliates, so
     long as Mr. Buffett and Berkshire and such Affiliates are Beneficial Owners
     of less than 45% of the Common Shares.  In determining whether any officer
     of Berkshire or of any of its Affiliates (other than Mr. Buffett or another
     officer, if any, who is an Affiliate of Berkshire or any of its Affiliates)
     is an "Acquiring Person", or in determining for purposes of Section 1(c)
     the number of Common Shares of which such an officer is the "Beneficial
     Owner" or which such an officer may "beneficially own", Common Shares of
     which Mr. Buffett, Berkshire or any Affiliate thereof is the "Beneficial
     Owner" as defined herein shall be disregarded.  In

                                       3
<PAGE>
 
     determining whether Mr. Buffett or Berkshire or their respective Affiliates
     is an "Acquiring Person", or in determining, for purposes of Section 1(c),
     the number of Common Shares of which Mr. Buffett, Berkshire or their
     respective Affiliates is the "Beneficial Owner" or which Mr. Buffett,
     Berkshire or their respective Affiliates may "beneficially own", Common
     Shares of which an Associate of Mr. Buffett, Berkshire or their respective
     Affiliates that is not also an Affiliate of Mr. Buffett, Berkshire or their
     respective Affiliates is the "Beneficial Owner" shall be disregarded.  The
     provisions of the following sentence shall be applicable to Mr. Buffett,
     Berkshire and their respective Affiliates with "45%" substituted for "20%"
     in the places where the expression "20%" appears in such sentence.  No
     Person shall become an "Acquiring Person" as the result of an acquisition
     of Common Shares by the Company which, by reducing the number of shares
     outstanding, increases the proportionate number of shares beneficially
     owned by such Person to 20% or more of the Common Shares then outstanding;
                                                                               
     provided, however, that if a Person shall become the beneficial owner of
     --------                                                                
     20% or more of the Common Shares then outstanding by reason of share
     purchases by the Company and shall, after such share purchases by the
     Company, either (i) become the Beneficial Owner (as a result of actions
     taken by such Person or its Affiliates or Associates) of additional Common
     Shares constituting 1%

                                       4
<PAGE>
 
     or more of the then outstanding Common Shares, or (ii) engage in or propose
     to engage in one or more of the transactions enumerated in Clauses (1)
     through (5) of Subsection (A) of Section 11(a)(ii) hereof, then such person
     shall be deemed to be an "Acquiring Person."
          (b) "Affiliate" and "Associate" shall have the respective meanings
     ascribed to such terms in Rule 12b-2 of the General Rules and Regulations
     under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
     as in effect on June 30, 1986.
          (c) A Person shall be deemed the "Beneficial Owner" of and shall be
     deemed to "beneficially own" any securities:
                 (i) which such Person or any of such Person's Affiliates or
          Associates beneficially owns, directly or indirectly;
                 (ii) which such Person or any of such Person's Affiliates or
          Associates has (A) the right to acquire (whether such right is
          exercisable immediately or only after the passage of time) pursuant to
          any agreement, arrangement or understanding, or upon the exercise of
          conversion rights, exchange rights, rights (other than these Rights),
          warrants or options, or otherwise; provided, however, that a Person
                                             --------  -------               
          shall not be deemed the Beneficial Owner of, or to beneficially own,
          securities tendered pursuant to a tender or exchange

          Affiliates or Associates until such tendered securities are accepted
          for purchase or exchange; or (B) the right to vote pursuant to any
          agreement, arrangement or understanding, except where such right to
          vote is limited to the approval of the merger of a Subsidiary of the
          Company with another person; provided, however, that a Person shall
                                       --------  -------                     
          not be deemed the Beneficial Owner of, or to beneficially own, any
          security if the agreement, arrangement or understanding to vote such
          security (1) arises solely from a revocable proxy or consent given to
          such Person in response to a public proxy or consent solicitation made
          pursuant to, and in accordance with, the applicable rules and
          regulations of the Exchange Act and (2) is not also then reportable on
          Schedule 13D under the Exchange Act (or any comparable or successor
          report); or

                 (iii)  which are beneficially owned, directly or indirectly, by
          any other Person with which such Person or any of such Person's
          Affiliates or Associates has any agreement, arrangement or
          understanding for the purpose of acquiring, holding, voting (except to
          the extent contemplated by the proviso to Section l(c)(ii)(B)) or
          disposing of any securities of the Company.

held.  As of the Distribution Date, the Rights will be evidenced solely by such
Right Certificates.
     (b) On July 10, 1986 or as soon as practicable thereafter, the Company will
send a copy of a Summary of Rights to Purchase Preferred Shares, in
substantially the form of Exhibit C hereto (the "Summary of Rights"), by first-
class, postage-prepaid mail, to each record holder of Common Shares as of the
close of business on July 10, 1986, at the address of such holder shown on the

outstanding as of July 10, 1986, 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 Final Expiration
Date), the surrender for transfer of any certificate for Common Shares
outstanding on July 10, 1986, with or without a copy of the Summary of Rights
attached thereto, shall also constitute the transfer of the Rights associated
with the Common Shares represented thereby.
     (c) Certificates for Common Shares which become outstanding (including,
without limitation, reacquired Common Shares referred to in the last sentence of
this paragraph (c)) after July 10, 1986 but prior to the earliest of the
Distribution Date, the Redemption Date or the Final Expiration Date shall have
impressed on, printed on, written on or otherwise affixed to them the following

          This certificate also evidences and entitles the holder hereof to

          "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 PSA, 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.
          PSA, Inc. will mail to the holder of this certificate a copy of the
          Rights Agreement without charge after receipt of a written request
          therefor.  Under certain circumstances, Rights beneficially owned by
          Acquiring Persons (as defined in the Rights Agreement) 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 Company purchases or acquires any Common Shares after July
10, 1986 but prior to the Distribution Date, any Rights associated with such
Common Shares shall be deemed cancelled and retired so that the Company shall
not be entitled to exercise any Rights associated with the Common Shares which
are no longer outstanding.

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

                                       11
<PAGE>
 
legends, summaries or endorsements printed thereon as the Company may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Rights may from time to time be listed, or to conform to
usage.  Subject to the provisions of Section 22 hereof, the Right Certificates
shall entitle the holders thereof to purchase such number of one one-hundredths
of a Preferred Share as shall be set forth therein at the price per one one-
hundredth of a Preferred Share set forth therein (the "Purchase Price"), but the
number of such one one-hundredths of a Preferred Share and the Purchase Price
shall be subject to adjustment as provided herein.

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

                                       12
<PAGE>
 
Right Certificates, nevertheless, may be countersigned by the Rights Agent and
issued and delivered by the Company with the same force and effect as though the
person who signed such Right Certificates had not ceased to be such officer of
the Company; and any Right Certificate may be signed on behalf of the Company by
any person who, at the actual date of the execution of such Right Certificate,
shall be a proper officer of the Company to sign such Right Certificate,
although at the date of the execution of this Rights Agreement any such person
was not such an officer.

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

     Section 6.  Transfer, Split Up, Combination and Exchange of Right
                 -----------------------------------------------------
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates.  Subject
- ---------------------------------------------------------------------          
to the provisions of Section 14 hereof, at any time after the close of business
on the Distribution Date, and at or prior to the close of business on the
earlier of the Redemption Date or the Final Expiration Date, any Right
Certificate or Right Certificates 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-hundredths of a

                                       13
<PAGE>
 
Preferred Share as the Right Certificate or Right Certificates surrendered then
entitled such holder to purchase.  Any registered holder desiring to transfer,
split up, combine or exchange any Right Certificate or Right Certificates shall
make such request in writing delivered to the Rights Agent, and shall surrender
the Right Certificate or Right Certificates to be transferred, split up,
combined or exchanged at the principal offices of the Rights Agent or its office
in New York, New York.  Thereupon the Rights Agent shall countersign and deliver
to the person entitled thereto a Right Certificate or Right Certificates, as the
case may be, as so requested.  The Company may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Right
Certificates.

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

     Section 7.  Exercise of Rights; Purchase Price; Expiration Date of Rights.
                 ----------------------------------- -------------------------  
(a)  The registered holder of any Right Certificate may exercise the Rights
evidenced thereby (except as otherwise provided herein) in whole or in part at
any time after the Distribution Date upon surrender of the Right Certificate,
with the form of election to purchase on the reverse side thereof duly executed,
to the Rights Agent at the principal offices of the Rights Agent, together with
payment of the Purchase Price for each one one-hundredth of a Preferred Share as
to which the Rights are exercised, at or prior to the earlier of (i) the close
of business on July 10, 1996 (the "Final Expiration Date"), or (ii) the time at
which the Rights are redeemed as provided in Section 23 hereof (the "Redemption
Date").
     (b) The Purchase Price for each one one-hundredth of a Preferred Share
pursuant to the exercise of a Right shall initially be $100, shall be subject to
adjustment from time to time as provided in Sections 11 and 13 hereof and shall
be payable in lawful money of the United States of America in accordance with
paragraph (c) below.
     (c) Upon receipt of a Right Certificate representing exercisable Rights,
with the form of election to purchase duly executed, accompanied by payment of
the Purchase Price for the shares to be purchased and an amount equal to any
applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 9 hereof in cash, or by certified check
or cashier's check payable to the order of the

                                       15
<PAGE>
 
Company, the Rights Agent shall thereupon promptly (i) (A) requisition from any
transfer agent of the Preferred Shares certificates for the number of Preferred
Shares to be purchased and the Company hereby irrevocably authorizes its
transfer agent to comply with all such requests, or (B) requisition from the
depositary agent depositary receipts representing such number of one one-
hundredths 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 Company
hereby directs the depositary agent to comply with such request, (ii) when
appropriate, requisition from the Company the amount of cash to be paid in lieu
of issuance of fractional shares in accordance with Section 14 hereof, (iii)
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, deliver such cash to or upon
the order of the registered holder of such Right Certificate.
     (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

                                       16

Certificate or to his duly authorized assigns, subject to the provisions of
Section 14 hereof.

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

     Section 9.  Reservation and Availability of Preferred Shares.  The Company
                 ------------------------------------------------              
covenants and agrees that it will cause to be reserved and kept available out of
its authorized and unissued Preferred Shares or any Preferred Shares held in its
treasury, the number of Preferred Shares that will be sufficient to permit the
exercise in full of all outstanding Rights.

                                       17
<PAGE>
 
     The Company covenants and agrees that it will take all such action as may
be necessary to ensure that all Preferred Shares delivered upon exercise of
Rights shall, at the time of delivery of the certificates for such Preferred
Shares (subject to payment of the Purchase Price), be duly and validly
authorized and issued and fully paid and nonassessable shares.

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

     Section 10.  Preferred Shares Record Date.  Each person in whose name any
                  ----------------------------                                
certificate for Preferred Shares is issued upon the exercise of Rights shall for
all purposes be deemed

                                       18
<PAGE>
 
to have become the holder of record of the Preferred Shares represented thereby
on, and such certificate shall be dated, the date upon which the Right
Certificate evidencing such Rights was duly surrendered and payment of the
Purchase Price (and any applicable transfer taxes) was made; provided, however,
                                                             --------  ------- 
that if the date of such surrender and payment is a date upon which the
Preferred Shares transfer books of the Company are closed, such person shall be
deemed to have become the record holder of such shares on, and such certificate
shall be dated, the next succeeding Business Day on which the Preferred Shares
transfer books of the Company are open.  Prior to the exercise of the Rights
evidenced thereby, the holder of a Right Certificate shall not be entitled to
any rights of a holder of Preferred Shares for which the Rights shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

     Section 11.  Adjustment of Purchase Price, Number of Shares or Number of
                  -----------------------------------------------------------
Rights.  The Purchase Price, the number of Preferred Shares covered by each
- ------                                                                     
Right and the number of Rights outstanding are subject to adjustment from time
to time as provided in this Section 11.

     (a)  (i)  In the event the Company shall at any time after the date of this
Agreement (A) declare a dividend on the Preferred Shares payable in Preferred
Shares, (B) subdivide

                                       19
<PAGE>
 
the outstanding Preferred Shares, (C) combine the outstanding Preferred Shares
into a smaller number of Preferred Shares or (D) issue any shares of its capital
stock in a reclassification of the Preferred Shares (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), except as otherwise
provided in this Section 11(a), the Purchase Price in effect at the time of the
record date for such dividend or of the effective date of such subdivision,
combination or reclassification, and the number and kind of shares of capital
stock issuable on such date, shall be proportionately adjusted so that the
holder of any Right exercised after such time shall be entitled to receive the
aggregate number and kind of shares of capital stock which, if such Right had
been exercised immediately prior to such date and at a time when the Preferred
Shares transfer books of the Company were open, he would have owned upon such
exercise and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  If an event occurs which would require an
adjustment under both this Section 11(a)(i) and Section 11(a)(ii), 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).

          (ii) In the event
               (A) any Person shall become an Acquiring Person [except pursuant
          to a tender or exchange

                                       20

          offer for all outstanding Common Shares at a price and on terms
          determined by at least a majority of the members of the Board of
          Directors who are not officers of the Company to be both adequate and
          otherwise in the best interests of the Company and its shareholders
          (other than the Person or an Affiliate or Associate thereof on whose
          behalf the offer is made) (a "Permitted Offer")], or any Acquiring
          Person or any Associate or Affiliate of any Acquiring Person, at any
          time after the date of this Agreement, directly or indirectly, (1)
          except upon terms disclosed in a Permitted Offer, shall merge into the
          Company or otherwise combine with the Company and the Company shall be
          the continuing or surviving corporation of such merger or combination
          and the Common Shares of the Company shall remain outstanding and not
          changed into or exchanged for stock or other securities of any other
          Person or the Company or cash or any other property, (2) shall, in one
          or more transactions, other than in connection with the exercise of
          Rights or the exercise or conversion of securities exchangeable for or
          convertible into capital stock of the Company or any of its
          Subsidiaries, transfer any assets to the Company or any of its
          Subsidiaries in exchange (in whole or in part) for shares of any class
          of capital stock of the Company or any of its Subsidiaries or

                                       21
<PAGE>
 
          for securities exercisable for or convertible into shares of any class
          of capital stock of the Company or any of its Subsidiaries or
          otherwise obtain from the Company or any of its Subsidiaries, with or
          without consideration, any additional shares of any class of capital
          stock of the Company or any of its Subsidiaries or securities
          exercisable for or convertible into shares of any class of capital
          stock of the Company or any of its Subsidiaries (other than as part of
          a pro rata distribution to all holders of such shares of any class of
          capital stock of the Company or any of its Subsidiaries), (3) shall
          sell, purchase, lease, exchange, mortgage, pledge, transfer or
          otherwise dispose (in one or more transactions), to, from, with or of,
          as the case may be, the Company or any of its Subsidiaries, assets
          (including securities) on terms and conditions less favorable to the
          Company than the Company would be able to obtain in arm's-length
          negotiation with an unaffiliated third party, (4) shall receive any
          compensation from the Company or any of its Subsidiaries other than
          compensation at rates in accordance with the Company's (or its
          Subsidiaries') past practices, or (5) shall receive the benefit,
          directly or indirectly (except proportionately as a shareholder), of
          any loans, advances, guarantees, pledges or other financial assistance
          or any tax

                                       22

          credits or other tax advantage provided by the Company or any of its
          Subsidiaries, or
                    (B) during such time as there is an Acquiring Person, there
          shall be any reclassification of securities (including any reverse
          stock split), or recapitalization of the Company, or any merger or
          consolidation of the Company with any of its Subsidiaries or any other
          transaction or series of transactions involving the Company or any
          Subsidiaries of the Company (whether or not with or into or otherwise
          involving an Acquiring Person) which has the effect, directly or
          indirectly, of increasing by more than 1% the proportionate share of
          the outstanding shares of any class of equity securities or of
          securities exercisable for or convertible into securities of the
          Company or any of its Subsidiaries which is directly or indirectly
          owned by any Acquiring Person or any Associate or Affiliate of any
          Acquiring Person,

then, and in each such case, proper provision shall be made so that each holder
of a Right, except as provided below, shall thereafter have a right to receive,
upon exercise thereof in accordance with the terms of this Agreement, in lieu of
Preferred Shares, such number of Common Shares as shall equal the result
obtained by (x) multiplying the then current Purchase Price by the number of one
one-hundredths of a

                                       23
<PAGE>
 
Preferred Share for which a Right is then exercisable and dividing that product
by (y) 50% of the then current per share market price of the Common Shares
(determined pursuant to Section 11(d)) on the fifth day after the earlier of the
date of the occurrence or the date of the first public announcement of any one
of the events listed above in this Section 11(a)(ii); 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).  Notwithstanding the foregoing, upon the occurrence of any of
the events listed above in this Section 11(a)(ii), any Rights that are or were
on or after the earlier of the Distribution Date or the Shares Acquisition Date
beneficially owned by an Acquiring Person (or any Associate or Affiliate of such
Acquiring Person) shall become void and any holder of such Rights shall
thereafter have no right to exercise such Rights under any provision of this
Agreement.  The Company shall not enter into any transaction of the kind listed
in this Section 11(a)(ii) if at the time of such transaction there are any
rights, warrants, instruments or securities outstanding or any agreements or
arrangements which, as a result of the consummation of such transaction, would
substantially diminish or otherwise eliminate the benefits intended to be
afforded by the Rights.  Any Right Certificate issued pursuant to Section 3
hereof that represents Rights beneficially owned by an

                                       24
<PAGE>
 
Acquiring Person or any Associate or Affiliate thereof and any Right Certificate
issued at any time upon the transfer of any Rights to an Acquiring Person or any
Associate or Affiliate thereof or to any nominee of such Acquiring Person,
Associate or Affiliate, and any Right Certificate issued pursuant to Section 6,
7(d) or 22 hereof or this Section 11 upon transfer, exchange, replacement or
adjustment by any other Right Certificate referred to in this sentence, shall
contain the following legend:

          The Rights represented by this Right Certificate were issued to a
          Person who was an Acquiring Person or an Affiliate or an Associate of
          an Acquiring Person (as such terms are defined in the Rights
          Agreement).  This Right Certificate and the Rights represented hereby
          may become void in the circumstances specified in Section 11(a)(ii) of
          the Rights Agreement;

provided that the Rights Agent shall not be under any responsibility to
- -------- ----                                                          
ascertain the existence of facts that would require the imposition of such
legend but shall be required to impose such legend only if instructed to do so
by the Company or if a holder fails to certify upon transfer or exchange in the
space provided on the Right Certificate that such holder is not an Acquiring
Person or an Affiliate or Associate thereof.

          (iii)  In the event that there shall not be sufficient issued but not
outstanding, or authorized but unissued, Common Shares to permit the exercise in
full of the Rights in accordance with Section 11(a)(ii), the Company shall take
all such action as may be necessary to authorize

                                       25
<PAGE>
 
additional Common Shares for issuance upon exercise of the Rights.
          (b) In case the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of Preferred Shares entitling them
(for a period expiring within 45 calendar days after such record date) to
subscribe for or purchase Preferred Shares (or shares having the same rights,
privileges and preferences as the Preferred Shares ("equivalent preferred
shares")) or securities convertible into Preferred Shares or equivalent
preferred shares at a price per Preferred Share or equivalent preferred share
(or having a conversion price per share, if a security convertible into
Preferred Shares or equivalent preferred shares) less than the then current per
share market price of the Preferred Shares (as defined in Section 11(d)) on such
record date, the Purchase Price to be in effect after such record date shall be
determined by multiplying the Purchase Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the number of
Preferred Shares outstanding on such record date plus the number of Preferred
Shares which the aggregate offering price of the total number of Preferred
Shares and/or equivalent preferred shares so to be offered (and/or the aggregate
initial conversion price of the convertible securities so to be offered) would
purchase at such current market price and the denominator of which shall be the
number of Preferred Shares outstanding on such record date plus the number of
additional Preferred Shares and/or

                                       26
<PAGE>
 
equivalent preferred shares to be offered for subscription or purchase (or into
which the convertible securities so to be offered are initially convertible).
In case such subscription price may be paid in a consideration part or all of
which shall be in a form other than cash, the value of such consideration shall
be as determined in good faith by the Board of Directors of the Company, whose
determination shall be described in a statement filed with the Rights Agent.
Preferred Shares owned by or held for the account of the Company shall not be
deemed outstanding for the purpose of any such computation.  Such adjustment
shall be made successively whenever such a record date is fixed; and in the
event that such rights or warrants are not so issued, the Purchase Price shall
be adjusted to be the Purchase Price which would then be in effect if such
record date had not been fixed.
          (c) In case the Company shall fix a record date for the making of a
distribution to all holders of the Preferred Shares (including any such
distribution made in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription rights or warrants (excluding those referred
to in Section 11(b)), 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

                                       27
<PAGE>
 
share market price of the Preferred Shares (as defined in Section 11(d)) on such
record date, less the fair market value (as determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent) of the portion of the assets or evidences
of indebtedness so to be distributed or of such subscription rights or warrants
applicable to one Preferred Share and the denominator of which shall be such
current per share market price of the Preferred Shares.  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 the Common Shares on any date shall be deemed to be
the average of the daily closing prices per share of such Common Shares for the
30 consecutive Trading Days (as such term is hereinafter defined) immediately
prior to such date; provided, however, that in the event that the current per
                    --------  -------                                        
share market price of the Common Shares is determined during a period following
the announcement by the issuer of such Common Shares of (A) a dividend or
distribution on such Common Shares payable in such Common Shares or securities
convertible into such Common Shares, or (B) any subdivision, combination or
reclassification of such Common Shares and prior to the

                                       28
<PAGE>
 
expiration of 30 Trading Days after the ex-dividend date for such dividend or
distribution, or the record date for such subdivision, combination or
reclassification, then, and in each such case, the current per share market
price shall be appropriately adjusted to reflect the current market price per
Common Share equivalent.  The closing price for each day shall be the last sale
price, regular way, or, in case no such sale takes place on such day, the
average of the closing bid and asked prices, regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the New York Stock Exchange or,
if the Common Shares 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 Common Shares are listed or admitted to trading or, if the Common
Shares are not listed or admitted to trading on any national securities
exchange, the last quoted price or, if not so quoted, the average of the high
bid and low asked prices in the over-the-counter market, as reported by the
National Association of Securities Dealers, Inc.  Automated Quotations System
("NASDAQ") or such other system then in use, or, if on any such date the Common
Shares are not quoted by any such organization, the average of the closing bid
and asked prices as furnished by a professional market maker making a market in
the Common Shares selected by the Board of Directors of the

                                       29
<PAGE>
 
Company.  The term "Trading Day" shall mean a day on which the principal
national securities exchange on which the Common Shares are listed or admitted
to trading is open for the transaction of business or, if the Common Shares are
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 the same
manner as set forth above for Common Shares in Section 11(d)(i).  If the current
per share market price of the Preferred Shares cannot be determined in the
manner provided above, 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 (appropriately adjusted to reflect any stock split, stock
dividend or similar transaction occurring after the date hereof), multiplied by
one hundred.  If neither the Common Shares nor the Preferred Shares are publicly
held or so listed or traded, "current per share market price" shall mean the
fair value per share as determined in good faith by the Board of Directors of
the Company, whose determination shall be described in a statement filed with
the Rights Agent.
          (e) No adjustment in the Purchase Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in the Purchase
Price; provided, however, that any adjustments which by reason of this Section
       --------  -------                                                      
11(e) are not required to be made shall be carried forward and

                                       30
<PAGE>
 
taken into account in any subsequent adjustment.  All calculations under this
Section 11 shall be made to the nearest cent or to the nearest ten-thousandth of
a Common Share or other share or one-millionth of a Preferred Share as the case
may be.  Notwithstanding the first sentence of this Section 11(e), any
adjustment required by this Section 11 shall be made no later than the earlier
of (i) three years from the date of the transaction which requires such
adjustment or (ii) the date of the expiration of the right to exercise any
Rights.
          (f) If as a result of an adjustment made pursuant to Section 11(a),
the holder of any Right thereafter exercised shall become entitled to receive
any shares of capital stock of the Company other than Preferred Shares,
thereafter the number of such other shares so receivable upon exercise of any
Right shall be subject to adjustment from time to time in a manner and on terms
as nearly equivalent as practicable to the provisions with respect to the
Preferred Shares contained in Section 11(a) through (c), inclusive, and the
provisions of Sections 7, 9, 10 and 13 with respect to the Preferred Shares
shall apply on like terms to any such other shares.
          (g) All Rights originally issued by the Company subsequent to any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-hundredths of a
Preferred Share purchasable from time to time hereunder upon

                                       31
<PAGE>
 
exercise of the Rights, all subject to further adjustment as provided herein.
          (h) Unless the Company shall have exercised its election as provided
in Section 11(i), upon each adjustment of the Purchase Price as a result of the
calculations made in Section 11(b) and (c), each Right outstanding immediately
prior to the making of such adjustment shall thereafter evidence the right to
purchase, at the adjusted Purchase Price, that number of one one-hundredths of a
Preferred Share (calculated to the nearest one one-millionth of a Preferred
Share) obtained by (i) multiplying (x) the number of one one-hundredths of a
share covered by a Right immediately prior to this adjustment by (y) the
Purchase Price in effect immediately prior to such adjustment of the Purchase
Price and (ii) dividing the product so obtained by the Purchase Price in effect
immediately after such adjustment of the Purchase Price.
          (i) The Company may elect on or after the date of any adjustment of
the Purchase Price to adjust the number of Rights, in substitution for any
adjustment in the number of one one-hundredths 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-hundredths 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

                                       32
<PAGE>
 
Rights (calculated to the nearest one ten-thousandth) obtained by dividing the
Purchase Price in effect immediately prior to adjustment of the Purchase Price
by the Purchase Price in effect immediately after adjustment of the Purchase
Price.  The Company shall make a public announcement of its election to adjust
the number of Rights, indicating the record date for the adjustment, and, if
known at the time, the amount of the adjustment to be made.  This record date
may be the date on which the Purchase Price is adjusted or any day thereafter,
but, if the Right Certificates have been issued, shall be at least 10 days later
than the date of the public announcement.  If Right Certificates have been
issued, upon each adjustment of the number of Rights pursuant to this Section
11(i), the Company shall, as promptly as practicable, cause to be distributed to
holders of record of Right Certificates on such record date Right Certificates
evidencing, subject to Section 14 hereof, the additional Rights to which such
holders shall be entitled as a result of such adjustment, or, at the option of
the Company, shall cause to be distributed to such holders of record in
substitution and replacement for the Right Certificates held by such holders
prior to the date of adjustment, and upon surrender thereof, if required by the
Company, new Right Certificates evidencing all the Rights to which such holders
shall be entitled after such adjustment.  Right Certificates so to be
distributed shall be issued, executed and countersigned in the manner provided
for herein and shall be registered in the names of the holders of record

                                       33
<PAGE>
 
of Right Certificates on the record date specified in the public announcement.
          (j) Irrespective of any adjustment or change in the Purchase Price or
the number of one one-hundredths 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-hundredths of a
Preferred Share which were expressed in the initial Right Certificates issued
hereunder.
          (k) Before taking any action that would cause an adjustment reducing
the Purchase Price below one one-hundredth of the then par value, if any, of the
Preferred Shares issuable upon exercise of the Rights, the Company shall take
any corporate action which may, in the opinion of its counsel, be necessary in
order that the Company may validly and legally issue fully paid and
nonassessable Preferred Shares at such adjusted Purchase Price.
          (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Right exercised after such record date of
the Preferred Shares and other capital stock or securities of the Company, if
any, issuable upon such exercise over and above the Preferred Shares and other
capital stock or securities of the Company, if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such

                                       34
<PAGE>
 
adjustment; provided, however, that the Company shall deliver to such holder a
            -----------------                                                 
due bill or other appropriate instrument evidencing such holder's right to
receive such additional shares upon the occurrence of the event requiring such
adjustment.
          (m) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that it in its sole discretion shall determine to be advisable in
order that any consolidation or subdivision of the Preferred Shares, issuance
wholly for cash of any Preferred Shares at less than the current market price,
issuance wholly for cash of Preferred Shares or securities which by their terms
are convertible into or exchangeable for Preferred Shares, dividends on
Preferred Shares payable in Preferred Shares or issuance of rights, options or
warrants referred to hereinabove in Section 11(b), hereafter made by the Company
to holders of its Preferred Shares shall not be taxable to such shareholders.
          (n) In the event that at any time after the date of this Agreement and
prior to the Distribution Date, the Company shall (i) declare or pay any
dividend on the Common Shares payable in Common Shares or (ii) effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares)
into a greater or lesser number of Common

                                       35
<PAGE>
 
Shares, then in any such case (i) the number of one one-hundredths of a
Preferred Share purchasable after such event upon proper exercise of each Right
shall be determined by multiplying the number of one one-hundredths of a
Preferred Share so purchasable immediately prior to such event by a fraction,
the numerator of which is the number of Common Shares outstanding immediately
before such event and the denominator of which is the number of Common Shares
outstanding immediately after such event, and (ii) each Common Share outstanding
immediately after such event shall have issued with respect to it that number of
Rights which each Common Share outstanding immediately prior to such event had
issued with respect to it. The adjustments provided for in this Section 11(n)
shall be made successively whenever such a dividend is declared or paid or such
a subdivision, combination or consolidation is effected. If an event occurs
which would require an adjustment under Section 11(a)(ii) and this Section
11(n), the adjustments provided for in this Section 11(n) shall be in addition
and prior to any adjustment required pursuant to Section 11(a)(ii).

          Section 12.  Certificate of Adjusted Purchase Price or Number of
                       ---------------------------------------------------
Shares.  Whenever an adjustment is made as provided in Sections 11 and 13
- ------                                                                   
hereof, the Company shall promptly (a) prepare a certificate setting forth such
adjustment, and a brief statement of the facts accounting for such adjustment,
(b) file with the Rights Agent and with each transfer agent for the Common
Shares or the Preferred Shares a

                                       36
<PAGE>
 
copy of such certificate and (c) mail a brief summary thereof to each holder of
a Right Certificate in accordance with Section 25 hereof.

          Section 13.  Consolidation, Merger or Sale or Transfer of Assets or
                       ------------------------------------------------------
Earning Power.  In the event, directly or indirectly, (a) the Company shall
- -------------                                                              
consolidate with, or merge with and into, any other Person, (b) any Person shall
consolidate with the Company, or merge with and into the Company and the Company
shall be the continuing or surviving corporation of such merger and, in
connection with such merger, all or part of the Common Shares shall be changed
into or exchanged for stock or other securities of any other Person (or the
Company) or cash or any other property, or (c) the Company shall sell or
otherwise transfer (or one or more of its Subsidiaries shall sell or otherwise
transfer), in one or more transactions, assets or earning power aggregating 50%
or more of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person other than the Company or one or more of
its wholly-owned Subsidiaries, then, and in each such case, proper provision
shall be made so that (i) each holder of a Right (except as otherwise provided
herein) shall thereafter have the right to receive, upon the exercise thereof in
accordance with the terms of this Agreement, such number of Common Shares of
such other Person (including the Company as successor thereto or as the
surviving corporation) as shall be equal to the result obtained by (x)
multiplying the then current Purchase Price by

                                       37
<PAGE>
 
the number of one one-hundredths of a Preferred Share for which a Right is then
exercisable (without taking into account any adjustment previously made pursuant
to Section 11(a)(ii) hereof) and dividing that product by (y) 50% of the then
current per share market price of the Common Shares of such other Person
(determined pursuant to Section 11(d)) on the date of consummation of such
consolidation, merger, sale or transfer; (ii) the issuer of such Common Shares
shall thereafter be liable for, and shall assume, by virtue of such
consolidation, merger, sale or transfer, all the obligations and duties of the
Company pursuant to this Agreement; (iii) the term "Company" shall thereafter be
deemed to refer to such issuer; and (iv) such issuer shall take such steps
(including, but not limited to, the reservation of a sufficient number of its
Common Shares in accordance with Section 9 hereof) in connection with such
consummation as may be necessary to assure that the provisions hereof shall
thereafter be applicable, as nearly as reasonably may be, in relation to the
Common Shares thereafter deliverable upon the exercise of the Rights.  The
Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the consummation of such transaction, would substantially
diminish or otherwise eliminate the benefits intended to be afforded by the
Rights.  The Company shall not consummate any such consolidation, merger, sale
or

                                       38
<PAGE>
 
transfer unless prior thereto the Company and such issuer shall have executed
and delivered to the Rights Agent a supplemental agreement so providing.  The
provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers.  This Section 13 shall not be
applicable to a transaction described in Subparagraphs (a) or (b) of this
Section 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 being offered to the
remaining holders of Common Shares pursuant to such transaction is the same as
the form of consideration paid pursuant to such Permitted Offer.  Upon
consummation of any transaction described in the foregoing sentence, all Rights
shall expire.

          Section 14.  Fractional Rights and Fractional Shares.  (a)  The
                       ---------------------------------------           
Company shall not be required to issue fractions of Rights or to distribute
Right Certificates which evidence fractional Rights.  In lieu of such fractional
Rights, there shall be paid to the registered holders of the Right Certificates
with regard to which such fractional Rights would otherwise be issuable, an
amount in cash equal to the same fraction of the current market value of a whole
Right.

                                       39
<PAGE>
 
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 of Directors of
the Company.  If on any such date no such market maker is making a market in the
Rights the fair value of the Rights on such date as determined

                                       40
<PAGE>
 
in good faith by the Board of Directors of the Company shall be used.
          (b) The Company shall not be required to issue fractions of Preferred
Shares (other than fractions which are integral multiples of one one-hundredth
of a Preferred Share) upon exercise of the Rights or to distribute certificates
which evidence fractional Preferred Shares (other than fractions which are
integral multiples of one one-hundredth of a Preferred Share).  Fractions of
Preferred Shares in integral multiples of one one-hundredth of a Preferred Share
may, at the election of the Company, be evidenced by depositary receipts,
pursuant to an appropriate agreement between the Company and a depositary
selected by it, provided that such agreement shall provide that the holders of
such depositary receipts shall have all the rights, privileges and preferences
to which they are entitled as beneficial owners of the Preferred Shares
represented by such depositary receipts.  In lieu of fractional Preferred Shares
that are not integral multiples of one one-hundredth of a Preferred Share, the
Company shall pay to the registered holders of Right Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one Preferred Share. For purposes of
this Section 14(b), the current market value of a Preferred Share shall be the
closing price of a Preferred Share (as determined pursuant to the second
sentence of

                                       41
<PAGE>
 
Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
such exercise.
          (c) The holder of a Right by the acceptance of the Right expressly
waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right (except as provided above).

          Section 15.  Rights of Action.  All rights of action in respect of
                       ----------------                                     
this Agreement, excepting the rights of action given to the Rights Agent under
Section 18 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Common Shares), may, in his own behalf and for his own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Company to enforce, or otherwise act in respect of, his right to
exercise the Rights evidenced by such Right Certificate in the manner provided
in such Right Certificate and in this Agreement.  Without limiting the foregoing
or any remedies available to the holders of Rights, it is specifically
acknowledged that the holders of Rights would not have an adequate remedy at law
for any breach of this Agreement and will be entitled to specific performance of
the obligations under, and injunctive

                                       42
<PAGE>
 
relief against actual or threatened violations of, the obligations of any Person
subject to this Agreement.

          Section 16.  Agreement of Right Holders.  Every holder of a Right, by
                       --------------------------                              
accepting the same, consents and agrees with the Company and the Rights Agent
and with every other holder of a Right that:
          (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 principal offices of the Rights Agent or at its office in New York, New
York, duly endorsed or accompanied by a proper instrument of transfer; and
          (c) the Company and the Rights Agent may deem and treat the person in
whose name the Right Certificate (or, prior to the Distribution Date, the
associated Common Shares certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Right Certificates or the associated Common Shares
certificate made by anyone other than the Company or the Rights Agent) for all
purposes whatsoever, and neither the Company nor the Rights Agent shall be
affected by any notice to the contrary.

          Section 17.  Right Certificate Holder Not Deemed a Shareholder.  No
                       -------------------------------------------------     
holder, as such, of any Right Certificate

                                       43
<PAGE>
 
shall be entitled to vote, receive dividends or be deemed for any purpose the
holder of the Preferred Shares or any other securities of the Company which may
at any time be issuable on the exercise of the Rights represented thereby, nor
shall anything contained herein or in any Right Certificate be construed to
confer upon the holder of any Right Certificate, as such, any of the rights of a
shareholder of the Company or any right to vote for the election of directors or
upon any matter submitted to shareholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting shareholders (except as provided in Section 24 hereof),
or to receive dividends or subscription rights, or otherwise, until the Right or
Rights evidenced by such Right Certificate shall have been exercised in
accordance with the provisions hereof.

     Section 18.  Concerning the Rights Agent.  The Company agrees to pay to the
                  ---------------------------                                   
Rights Agent reasonable compensation for all services rendered by it hereunder
and, from time to time, on demand of the Rights Agent, its reasonable expenses
and counsel fees and other disbursements incurred in the 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 by the Rights Agent in connection with the acceptance
and

                                       44
<PAGE>
 
administration of this Agreement, including the costs and expenses of defending
against any claim of liability in the premises.

     The Rights Agent shall be protected and shall incur no liability for, or in
respect of any action taken, suffered or omitted by it in connection with, its
administration of this Agreement, in reliance upon any Right Certificate or
certificate for the Preferred Shares or Common Shares or for other securities of
the Company, instrument of assignment or transfer, power of attorney,
endorsement, affidavit, letter, notice, direction, consent, certificate,
statement, or other paper or document believed by it to be genuine and to be
signed, executed and, where necessary, verified or acknowledged, by the proper
person or persons, or otherwise upon the advice of counsel as set forth in
Section 20 hereof.

     Section 19.  Merger or Consolidation or Change of Name of Rights Agent.
                  ---------------------------------------------------------  
Any corporation into which the Rights Agent or any successor Rights Agent may be
merged or with which it may be consolidated, or any corporation resulting from
any merger or consolidation to which the Rights Agent or any successor Rights
Agent shall be a party, or any corporation succeeding to the corporate trust
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

                                       45
<PAGE>
 
of Section 21 hereof. In case at the time such successor Rights Agent shall
succeed to the agency created by this Agreement, any of the Right Certificates
shall have been countersigned but not delivered, any such successor Rights Agent
may adopt the countersignature of the predecessor Rights Agent and deliver such
Right Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall have the full force provided in the Right Certificates
and in this Agreement.

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

                                       46
<PAGE>
 
which the Company and the holders of Right Certificates, by their acceptance
thereof, shall be bound:
     (a) The Rights Agent may consult with legal counsel (who may be legal
counsel for the Company), and the opinion of such counsel shall be full and
complete authorization and protection to the Rights Agent as to any action taken
or omitted by it in good faith and in accordance with such opinion.
     (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter be
proved or established by the Company prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be deemed to be conclusively proved and
established by a certificate signed by any one of the Chairman of the Board, the
President, any Vice President, the Treasurer or the Secretary of the Company and
delivered to the Rights Agent; and such certificate shall be full authorization
to the Rights Agent for any action taken or suffered in good faith by it under
the provisions of this Agreement in reliance upon such certificate.
     (c) The Rights Agent shall be liable hereunder to the Company and any other
Person only for its own negligence, bad faith or willful misconduct.

statements of fact or recitals contained in this Agreement or in the Right
Certificates (except its

                                       47

countersignature thereof) or be required to verify the same, but all such
statements and recitals are and shall be deemed to have been made by the Company
only.
     (e) The Rights Agent shall not be under any responsibility in respect of
the validity of this Agreement or the execution and delivery hereof (except the
due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Right Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Right Certificate; nor shall it
be responsible for any change in the exercisability of the Rights (including the
Rights becoming void pursuant to Section 11(a)(ii) hereof) or any adjustment in
the terms of the Rights (including the manner, method or amount thereof)
provided for in Section 3, 11, 13 or 23, or the ascertaining of the existence of
facts that would require any such change or adjustment (except with respect to
the exercise of Rights evidenced by Right Certificates after actual notice that
such change or adjustment is required); nor shall it by any act hereunder be
deemed to make any representation or warranty as to the authorization or
reservation of any Preferred Shares to be issued pursuant to this Agreement or
any Right Certificate or as to whether any Preferred Shares will, when issued,
be validly authorized and issued, fully paid and nonassessable.
     (f) The Company agrees that it will perform, execute, acknowledge and
deliver or cause to be performed, executed,

                                       48

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 President, any Vice President, the
Secretary or the Treasurer of the Company, and to apply to such officers for
advice or instructions in connection with its duties, and it shall not be liable
for any action taken or suffered by it in good faith in accordance with
instructions of any such officer or for any delay in acting while waiting for
those instructions.
     (h) The Rights Agent and any shareholder, director, officer or employee of
the Rights Agent may buy, sell or deal in any of the Rights or other securities
of the Company or become pecuniarily interested in any transaction in which the
Company may be interested, or contract with or lend money to the Company or
otherwise act as fully and freely as though it were not Rights Agent under this
Agreement.  Nothing herein shall preclude the Rights Agent from acting in any
other capacity for the Company or for any other legal entity.
     (i) The Rights Agent may execute and exercise any of the rights or powers
hereby vested in it or perform any duty hereunder either itself or by or through
its attorneys or agents, and the Rights Agent shall not be answerable or

                                       49
<PAGE>
 
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.

          Section 21.  Change of Rights Agent.  The Rights Agent or any
                       ----------------------                          
successor Rights Agent may resign and be discharged from its duties under this
Agreement upon 30 days' notice in writing mailed to the Company and to each
transfer agent of the Common Shares or Preferred Shares by registered or
certified mail, and to the holders of the Right Certificates by first-class
mail.  The Company may remove the Rights Agent or any successor Rights Agent
upon 30 days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to each transfer agent of the Common Shares or
Preferred Shares by registered or certified mail, and to the holders of the
Right Certificates by first-class mail.  If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall appoint
a successor to the Rights Agent.  If the Company shall fail to make such
appointment within a period of 30 days after giving notice of such removal or
after it has been notified in writing of such resignation or incapacity by the
resigning or incapacitated Rights Agent or by the holder of a Right Certificate
(who shall, with such notice, submit his Right Certificate for inspection by the
Company), then the registered holder of any Right Certificate may apply to any

                                       50
<PAGE>
 
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 (or of any other state of the United States
so long as such corporation is authorized to do business as a banking
institution in the State of New York), in good standing, having an office in the
State of New York, which is authorized under such laws to exercise corporate
trust powers and is subject to supervision or examination by federal or state
authority and which has at the time of its appointment as Rights Agent a
combined capital and surplus of at least $50 million.  After appointment, the
successor Rights Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Rights Agent without
further act or deed; but the predecessor Rights Agent shall deliver and transfer
to the successor Rights Agent any property at the time held by it hereunder, and
execute and deliver any further assurance, conveyance, act or deed necessary for
the purpose.  Not later than the effective date of any such appointment the
Company shall file notice thereof in writing with the predecessor Rights Agent
and each transfer agent of the Common Shares or Preferred Shares, and mail a
notice thereof in writing to the registered holders of the Right Certificates.
Failure to give any notice provided for in this Section 21, however, or any
defect therein, shall not affect the legality or validity of

                                       51
<PAGE>
 
the resignation or removal of the Rights Agent or the appointment of the
successor Rights Agent, as the case may be.

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

     Section 23.  Redemption.  (a)  The Board of Directors of the Company may,
                  ----------                                                  
at its option, at any time prior to such time as any Person becomes an Acquiring
Person, redeem all but not less than all the then outstanding Rights at a
redemption price of $.05 per Right, 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").
     (b) Immediately upon the action of the Board of Directors of the Company
ordering the redemption of the Rights, 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.  Within 10 days after the action of the Board of Directors ordering the
redemption of the Rights, the Company shall give notice of such redemption to
the holders of

                                       52
<PAGE>
 
the then outstanding Rights by mailing such notice to all such holders at their
last addresses as they appear upon the registry books of the Rights Agent or,
prior to the Distribution Date, on the registry books of the transfer agent for
the Common Shares.  Any notice which is mailed in the manner herein provided
shall be deemed given, whether or not the holder receives the notice.  Each such
notice of redemption will state the method by which the payment of the
Redemption Price will be made.  Neither the Company nor any of its Affiliates or
Associates may redeem, acquire or purchase for value any Rights at any time in
any manner other than that specifically set forth in this Section 23, and other
than in connection with the purchase of Common Shares prior to the Distribution
Date.

     Section 24.  Notice of Certain Events.  In case the Company shall propose
                  ------------------------                                    
(a) 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 regular quarterly cash dividend) or (b) 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, or (c) to effect any reclassification of
its Preferred Shares (other than a reclassification involving only the
subdivision of outstanding Preferred Shares), or (d) to effect any consolidation
or merger into or with, or to effect any sale or other transfer (or to permit
one or more of

                                       53
<PAGE>
 
its Subsidiaries to effect any sale or other transfer), in one or more
transactions, of 50% or more of the assets or earning power of the Company and
its Subsidiaries (taken as a whole) to, any other Person, or (e) to effect the
liquidation, dissolution or winding up of the Company, or (f) to declare or pay
any dividend on the Common Shares payable in Common Shares or to effect a
subdivision, combination or consolidation of the Common Shares (by
reclassification or otherwise than by payment of dividends in Common Shares),
then, in each such case, the Company shall give to each holder of a Right
Certificate, in accordance with Section 25 hereof, a notice of such proposed
action, which shall specify the record date for the purposes of such stock
dividend, or distribution of rights or warrants, or the date on which such
reclassification, consolidation, merger, sale, transfer, liquidation,
dissolution, or winding up is to take place and the date of participation
therein by the holders of the Common Shares and/or 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 (a) or (b) 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 Common Shares and/or Preferred Shares, whichever shall be the
earlier.

shall occur, then, in any such case, the Company shall as soon as practicable
thereafter give to each holder of a Right Certificate, in accordance with
Section 25 hereof, a notice of the occurrence of such event, which shall specify
the event and the consequences of the event to holders of Rights under Section
11(a)(ii) hereof.

Agreement by or for the benefit of the Company or the Rights Agent shall bind

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

     PSA, Inc., a corporation organized and existing under the General
Corporation Law of the State of Delaware (hereinafter called the "Corporation"),
hereby certifies that the following resolution was adopted by the Board of
Directors of the Corporation as required by Section 151 of the Delaware General
Corporation Law at a meeting duly called and held on June 30, 1986:

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

     Series D Junior Participating Preferred Stock:

                          I.  Designation and Amount
                              ----------------------

     The shares of such series shall be designated as "Series D Junior
Participating Preferred Stock" (the "Junior Preferred Stock") and the number of
shares constituting the Junior Preferred Stock shall be 90,000. Such number of
shares may be increased or decreased by resolution of the Board of Directors;
provided, that no decrease shall reduce the number of shares of Junior Preferred
- --------                                                                        
Stock to a number less than the number of shares then outstanding plus the
number of shares reserved for issuance upon the exercise of outstanding options,
rights or warrants or upon the conversion of any outstanding securities issued
by the Corporation convertible into Junior Preferred Stock.

                       II.  Dividends and Distributions
                            ---------------------------

           A. Subject to the prior and superior rights of the holders of any
     shares of any series of Preferred Stock or any similar stock ranking prior
     and superior to the Junior Preferred Stock with respect to dividends, the
     holders of shares of Junior Preferred Stock, in preference to the holders
     of Common Stock, par value $1.00 per share (the "Common Stock"), of the
     Corporation, and of any other junior stock, shall be entitled to receive,
     when, as and if declared by the Board of Directors out of funds legally
     available for the purpose, quarterly dividends payable in cash on the first
     day of March, June, September and December in each year (each such date
     being referred to herein as a "Quarterly Dividend Payment Date"),
     commencing on the first Quarterly Dividend Payment Date after the first
     issuance of a share or fraction of a share of Junior Preferred Stock, in an
     amount per share (rounded to the nearest cent) equal to the greater of (a)
     $10 or (b) subject to the provision for adjustment hereinafter set forth,
     100 times the aggregate per share amount of all cash dividends, and 100
     times the aggregate per share amount (payable in kind) of all non-cash
     dividends or other distributions, other than a dividend payable in shares
     of Common Stock or a subdivision of the outstanding shares of Common Stock
     (by reclassification or otherwise), declared on the Common Stock since the
     immediately preceding Quarterly Dividend Payment Date or, with respect to
     the first Quarterly Dividend Payment Date, since the first issuance of any
     share or fraction of a share of Junior Preferred Stock. In the event the
     Corporation shall at any time declare or pay any dividend on the Common
     Stock payable in shares of Common Stock, or effect a subdivision or
     combination or consolidation of the outstanding shares of Common Stock (by
     reclassification or otherwise than by payment of a dividend in shares of
     Common Stock) into a greater or lesser number of shares of Common Stock,
     then in each such case the amount to which holders of shares of Junior
     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
     Junior Preferred Stock as provided in paragraph (A) of this Section
     immediately after it declares a dividend or distribution on the Common
     Stock (other than a dividend payable in shares of Common Stock); provided
     that, in the event no dividend or

                                       61
<PAGE>
 
     distribution shall have been declared on the Common Stock during the period
     between any Quarterly Dividend Payment Date and the next subsequent
     Quarterly Dividend Payment Date, a dividend of $10 per share on the Junior
     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 Junior Preferred Stock from the Quarterly Dividend Payment Date
     next preceding the date of issue of such shares, unless the date of issue
     of such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case dividends on such shares shall begin to accrue
     from the date of issue of such shares, or unless the date of issue is a
     Quarterly Dividend Payment Date or is a date after the record date for the
     determination of holders of shares of Junior Preferred Stock entitled to
     receive a quarterly dividend and before such Quarterly Dividend Payment
     Date, in either of which events such dividends shall begin to accrue and be
     cumulative from such Quarterly Dividend Payment Date.  Accrued but unpaid
     dividends shall not bear interest.  Dividends paid on the shares of Junior
     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 Junior 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.

                              III.  Voting Rights
                                    -------------

     The holders of shares of Junior Preferred Stock shall have the following
voting rights:

          A.  Subject to the provision for adjustment hereinafter set forth,
     each share of Junior Preferred Stock shall entitle the holder thereof to
     100 votes on all matters submitted to a vote of the shareholders of the
     Corporation.  In the event the Corporation shall at any time declare or pay
     any dividend on the Common Stock payable in shares of Common Stock, or
     effect a subdivision or combination or consolidation of the outstanding
     shares of Common Stock (by reclassification or otherwise than by payment of
     a dividend in shares of Common Stock) into a greater or lesser number of
     shares of Common Stock, then in each such case the number of votes per
     share to which holders of shares of Junior Preferred Stock were entitled
     immediately prior to such event shall be adjusted by multiplying such
     number by a

                                       62
<PAGE>
 
     fraction, the numerator of which is the number of shares of Common Stock
     outstanding immediately after such event and the denominator of which is
     the number of shares of Common Stock that were outstanding immediately
     prior to such event.

          B.  Except as otherwise provided herein, in any other Certificate of
     Designations, creating a series of Preferred Stock or any similar stock, or
     by law, the holders of shares of Junior Preferred Stock and the holders of
     shares of Common Stock and any other capital stock of the Corporation
     having general voting rights shall vote together as one class on all
     matters submitted to a vote of shareholders of the Corporation.

          C.  Except as set forth herein, holders of Junior Preferred Stock
     shall have no voting rights.

                           IV.  Certain Restrictions
                                --------------------

          A.  Whenever quarterly dividends or other dividends or distributions
     payable on the Junior Preferred Stock as provided in Section II are in
     arrears, thereafter and until all accrued and unpaid dividends and
     distributions, whether or not declared, on shares of Junior 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 Junior 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 Junior Preferred
          Stock, except dividends paid ratably on the Junior Preferred Stock and
          all such parity stock on which dividends are payable or in arrears in
          proportion to the total amounts to which the holders of all such
          shares are then entitled;

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

                                       63
<PAGE>
 
               (iv) redeem or purchase or otherwise acquire for consideration
          any shares of Junior Preferred Stock, or any shares of stock ranking
          on a parity with the Junior 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 IV purchase or otherwise acquire such shares at such time and in
     such manner.

                             V.  Reacquired Shares
                                 -----------------

     Any shares of Junior Preferred Stock purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and cancelled promptly
after the acquisition thereof. All such shares shall upon their cancellation
become authorized but unissued shares of Preferred Stock and may be reissued as
part of a new series of Preferred Stock subject to the conditions and
restrictions on issuance set forth herein, in the Restated Certificate of
Incorporation, in any other Certificate of Designations creating a series of
Preferred Stock or any similar stock or as otherwise required by law.

                  VI.  Liquidation, Dissolution or Winding Up
                       --------------------------------------

     Upon any liquidation, dissolution or winding up of the Corporation, no
distribution shall be made (1) to the holders of shares of stock ranking junior
(either as to dividends or upon liquidation, dissolution or winding up) to the
Junior Preferred Stock unless, prior thereto, the holders of shares of Junior
Preferred Stock shall have received $100 per share, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, provided that the holders of shares of Junior
Preferred Stock shall be entitled to receive an aggregate amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount to be distributed per share to holders of shares of
Common Stock, or (2) to the holders of shares of stock ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Junior Preferred Stock, except distributions made ratably on the Junior
Preferred Stock and all such parity stock in proportion to the total

                                       64
<PAGE>
 
amounts to which the holders of all such shares are entitled upon such
liquidation, dissolution or winding up.  In the event the Corporation shall at
any time declare or pay any dividend on the Common Stock payable in shares of
Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the aggregate amount to which
holders of shares of Junior Preferred Stock were entitled immediately prior to
such event under the proviso in clause (1) of the preceding sentence shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

                       VII.  Consolidation, Merger, etc.
                             ---------------------------

     In case the Corporation shall enter into any consolidation, merger,
combination or other transaction in which the shares of Common Stock are
exchanged for or changed into other stock or securities, cash and/or any other
property, then in any such case each share of Junior Preferred Stock shall at
the same time be similarly exchanged or changed into an amount per share,
subject to the provision for adjustment hereinafter set forth, equal to 100
times the aggregate amount of stock, securities, cash and/or any other property
(payable in kind), as the case may be, into which or for which each share of
Common Stock is changed or exchanged.  In the event the Corporation shall at any
time declare or pay any dividend on the Common Stock payable in shares of Common
Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, then in each such case the amount set forth in the
preceding sentence with respect to the exchange or change of shares of Junior
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.

                               VIII.  Redemption
                                      ----------

     The shares of Junior Preferred Stock shall not be redeemable.

                                   IX.  Rank
                                        ----

     The Junior Preferred Stock shall rank junior with respect to the payment of
dividends and the distribution of assets to all series of any class of the
Corporation's Preferred Stock or any similar stock that specifically provide
that they shall rank prior to the Junior Preferred Stock. Nothing herein shall
preclude the Board from creating any series of Preferred Stock or any similar
stock ranking on a parity with or prior to the Junior Preferred Stock as to the
payment of dividends or the distribution of assets.

                                 X.  Amendment
                                     ---------

      The Restated Certificate of Incorporation of the Corporation shall not be
amended in any manner which would materially alter or change the powers,
preferences or special rights of the Junior Preferred Stock so as to affect them
adversely without the affirmative vote of the holders of at least two-thirds of
the outstanding shares of Junior Preferred Stock, voting together as a single
series.

      IN WITNESS WHEREOF, this Certificate of Designation, Preferences and
Rights is executed on behalf of the Corporation by its Chairman of the Board and
attested by its Secretary this ____ day of July, 1986.

                         SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES


     On June 30, 1986, the Board of Directors of PSA, Inc. (the "Company")
declared a dividend of one preferred share purchase right (a "Right") for each
outstanding share of Common Stock, par value $1.00 per share (the "Common
Shares"), of the Company.  The dividend is payable on July 10, 1986 to the
shareholders of record on that date.  Each Right entitles the registered holder
to purchase from the Company one one-hundredth of a share of Series D Junior
Participating Preferred Stock, par value $1.00 per share (the "Preferred
Shares"), of the Company, at a price of $100 per one one-hundredth of a
Preferred Share (the "Purchase Price"), subject to adjustment.  The description
and terms of the Rights are set forth in a Rights Agreement (the "Rights
Agreement") between the Company and Bank of America, N.T. & S.A., as Rights
Agent (the "Rights Agent").

     Until the earlier to occur of (i) 10 days following a public announcement
that a person or group of affiliated or associated persons (an "Acquiring
Person") acquired, or obtained the right to acquire, beneficial ownership of 20%
or more of the outstanding Common Shares or (ii) 10 days following the
commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 30% or more of such outstanding Common Shares
(the earlier of such dates being called the "Distribution Date"), the Rights
will be evidenced, with respect to any of the Common Share certificates
outstanding as of July 10, 1986, by such Common Share certificate with a copy of
this Summary of Rights attached thereto.  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 July 10,
1986 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 July 10, 1986, 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 such separate Right
Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date.  The Rights
will expire on July 10, 1996 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or unless the Rights are earlier redeemed by the
Company, in each case, as described below.

     The Purchase Price payable, and the number of Preferred Shares or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution (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 periodic cash dividends paid out of earnings or
retained earnings or dividends payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

     The number of outstanding Rights and the number of one one-hundredths of a
Preferred Share issuable upon exercise of each Right 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 per share but will be entitled to an aggregate
dividend of 100 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 $100 per share but will be entitled to an
aggregate payment of 100 times the payment made per Common Share.  Each
Preferred Share will have 100 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
100 times the amount received per Common Share.  These rights are protected by
customary antidilution provisions.

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

     In the event that the Company is acquired in a merger or other business
combination transaction or 50% or more of its

                                       76

consolidated assets or earning power are sold, proper provision will be made so
that each holder of a Right will thereafter have the right to receive, upon the
exercise thereof at the then current exercise price of the Right, that number of
shares of common stock of the acquiring company which at the time of such
transaction will have a market value of two times the exercise price of the
Right.  In the event that the Company is the surviving corporation in a merger
and the Common Shares are not changed or exchanged, or in the event that an
Acquiring Person engages in one of a number of self-dealing transactions
specified in the Rights Agreement, proper provision will be made so that each
holder of a Right, other than Rights that are beneficially owned by the
Acquiring Person on or after the earlier of the Distribution Date or the date an
Acquiring Person acquires 20% or more of the outstanding Common Shares (which
will thereafter be void), will thereafter have the right to receive upon
exercise that number of Common Shares having a market value of two times the
then current exercise price of the Right.

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

     At any time prior to the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of 20% or more of the outstanding
Common Shares, the Board of Directors of the Company may redeem the Rights in
whole, but not in part, at a price of $.05 per Right (the "Redemption Price").
Immediately upon the action of the Board of Directors ordering redemption of the
Rights, the right to exercise the Rights will terminate and the only right of
the holders of Rights will be to receive the Redemption Price.

     The terms of the Rights may be amended by the Board of Directors of the
Company without the consent of the holders of the Rights, including an amendment
to extend the Final Expiration Date, and, provided there is no Acquiring Person,
to extend the period during which the Rights may be redeemed, except that no
such amendment may adversely affect the interests of the holders of the Rights.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive dividends.
