          Preferred Share Purchase Rights          New York Stock Exchange


<PAGE>

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


                    On April 9, 1995, the Board of Directors of Frontier
          Corporation (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, of the Company (the
          "Common Stock").  The dividend is payable on April 24, 1995 (the
          "Record Date") to the shareowners of record on that date.  Each
          Right entitles the registered holder to purchase from the Company
          one one-hundredth of a share of Series A Junior Participating
          Class A Preferred Stock, par value $100 per share (the "Preferred
          Stock"), of the Company at a price of $80 per one one-hundredth
          of a share of Preferred Stock (the "Purchase Price"), subject to
          adjustment.  The description and terms of the Rights are set
          forth in a Rights Agreement dated as of April 9, 1995, as the
          same by be amended from time to time (the "Rights Agreement"),
          between the Company and The First National Bank of Boston, as
          Rights Agent (the "Rights Agent").

                    Until the earlier to occur of (i) 10 days following the
          first date of a public announcement that a person or group of
          affiliated or associated persons (an "Acquiring Person") have
          acquired beneficial ownership of 20% or more of the outstanding
          shares of Common Stock or such earlier date as a majority of the
          Board of Directors shall have become aware of the existence of an
          Acquiring Person, or (ii) 10 business days (or such later date as
          may be determined by action of the Board of Directors prior to
          such time as any person or group of affiliated persons becomes an
          Acquiring Person) 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 20% or more of the outstanding shares of
          Common Stock (the earlier of such dates being called the
          "Distribution Date"), the Rights will be evidenced, with respect
          to any of the Common Stock certificates outstanding as of the
          Record Date, by such Common Stock certificate together with a
          copy of this Summary of Rights.

                    The Rights Agreement provides that, until the
          Distribution Date (or earlier redemption or expiration of the
          Rights), the Rights will be transferred with and only with the
          Common Stock.  Until the Distribution Date (or earlier redemption
          or expiration of the Rights), new Common Stock certificates
          issued after the Record Date (including, without limitation, upon
          transfer or new issuances of Common Stock) 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
          shares of Common Stock outstanding as of the Record Date, even
          without such notation or a copy of this Summary of Rights, will
          also constitute (except as otherwise provided in the Rights
          Agreement) the transfer of the Rights associated with the shares
          of Common Stock represented by such certificate.  As soon as 


          
                   


<PAGE>
          practicable following the Distribution Date, separate
          certificates evidencing the Rights ("Right Certificates") will be
          mailed to holders of record of the Common Stock 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 April 24, 2005 (the "Final
          Expiration Date"), unless the Final Expiration Date is extended
          or unless the Rights are earlier redeemed or exchanged by the
          Company, in each case as described below.

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

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

                    Shares of Preferred Stock purchasable upon exercise of
          the Rights will not be redeemable.  Each share of Preferred Stock
          will be entitled, when, as and if declared, to a minimum
          preferential quarterly dividend payment of $1 per share but will
          be entitled to an aggregate dividend of 100 times the dividend
          declared per share of Common Stock.  In the event of liquidation,
          the holders of the Preferred Stock will be entitled to a minimum
          preferential liquidation payment of $100 per share (plus any
          accrued but unpaid dividends) but will be entitled to an
          aggregate payment of 100 times the payment made per share of
          Common Stock.  Each share of Preferred Stock will have 100 votes,
          voting together with the Common Stock.  Finally, in the event of
          any merger, consolidation or other transaction in which shares of
          Common Stock are converted or exchanged, each share of Preferred
          Stock will be entitled to receive 100 times the amount received
          per share of Common Stock.  These rights are protected by
          customary antidilution provisions.

<PAGE>
                    Because of the nature of the Preferred Stock's
          dividend, liquidation and voting rights, the value of the one
          one-hundredth interest in a share of Preferred Stock purchasable
          upon exercise of each Right should approximate the value of one
          share of Common Stock.

                    In the event that any person or group of affiliated or
          associated persons becomes an Acquiring Person, each holder of a
          Right, other than Rights beneficially owned by the Acquiring
          Person (which will thereupon become void), will thereafter have
          the right to receive upon exercise of a Right at the then current
          exercise price of the Right, that number of shares of Common
          Stock having a market value of two times the exercise price of
          the Right.

                    In the event that, after a person or group has become
          an Acquiring Person, the Company is acquired in a merger or other
          business combination transaction or 50% or more of its
          consolidated assets or earning power are sold, proper provision
          will be made so that each holder of a Right (other than Rights
          beneficially owned by an Acquiring Person which will have become
          void) 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 person with whom the
          Company has engaged in the foregoing transaction (or its parent),
          which number of shares at the time of such transaction will have
          a market value of two times the exercise price of the Right.  

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

                    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
          shares of Preferred Stock will be issued (other than fractions
          which are integral multiples of one one-hundredth of a share of
          Preferred Stock, 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 Stock on the last trading day prior to the date of
          exercise.

                    At any time prior to the time an Acquiring Person
          becomes such, the Board of Directors of the Company may redeem
          the Rights in whole, but not in part, at a price of $.01 per
          Right (the "Redemption Price"), subject to adjustment.  The 


                                        - 3 -
          
                   


<PAGE>
          redemption of the Rights may be made effective at such time, on
          such basis and with such conditions as the Board of Directors in
          its sole discretion may establish.  Immediately upon any
          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.

                    For so long as the Rights are then redeemable, the
          Company may, except with respect to the redemption price, amend
          the Rights in any manner.  After the Rights are no longer
          redeemable, the Company may, except with respect to the
          redemption price, amend the Rights in any manner that does not
          adversely affect the interests of holders of the Rights. 

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

                                   RIGHTS AGREEMENT
                                   ----------------

                Agreement, dated as of April 9, 1995, between FRONTIER
          CORPORATION, a New York corporation (the "Company"), and THE
          FIRST NATIONAL BANK OF BOSTON, a national banking association
          (the "Rights Agent").


                                       PREAMBLE
                                       --------


                The Board of Directors of the Company has authorized and
          declared a dividend of one preferred share purchase right (a
          "Right") for each share of Common Stock (as hereinafter defined)
          of the Company outstanding as of the Close of Business (as
          defined below) on April 24, 1995 (the "Record Date"), each Right
          representing the right to purchase one one-hundredth (subject to
          adjustment) of a share of Preferred Stock (as hereinafter
          defined), upon the terms and subject to the conditions herein set
          forth, and has further authorized and directed the issuance of
          one Right (subject to adjustment as provided herein) with respect
          to each share of Common Stock that shall become outstanding
          between the Record Date and the earlier of the Distribution Date
          and the Expiration Date (as such terms are hereinafter defined);
          provided, however, that Rights may be issued with respect to
          --------  -------
          shares of Common Stock that shall become outstanding after the
          Distribution Date and prior to the Expiration Date in accordance
          with Section 22. 

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

                Section 1.  Certain Definitions.  For purposes of this
                            -------------------
          Agreement, the following terms have the meaning indicated:

                (a)  "Acquiring Person" shall mean any Person (as such term
             is hereinafter defined) who or which shall be the Beneficial
             Owner (as such term is hereinafter defined) of 20% or more of
             the shares of Common Stock then outstanding, but shall not
             include an Exempt Person (as such term is hereinafter
             defined); provided, however, that if the Board of Directors of
                       --------  -------
             the Company determines in good faith that a Person who would
             otherwise be an "Acquiring Person" has become such
             inadvertently (including, without limitation, because (i) such
             Person was unaware that it beneficially owned a percentage of
             Common Stock that would otherwise cause such Person to be a
             "Acquiring Person") and without any intention of changing or
             influencing control of the Company, and such Person, as
             promptly as practicable after being advised of such
             determination, divests himself or itself of Beneficial
             Ownership of a sufficient number of shares of Common Stock so
             that such Person would no longer be an Acquiring Person, then
             such Person shall not be deemed to be or to have become an 

          
                   



<PAGE>
             "Acquiring Person" for any purposes of this Agreement. 
             Notwithstanding the foregoing, no Person shall become an
             "Acquiring Person" as the result of an acquisition of shares
             of Common Stock 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
             shares of Common Stock then outstanding, provided, however,
                                                      --------  -------
             that if a Person shall become the Beneficial Owner of 20% or
             more of the shares of Common Stock then outstanding by reason
             of such share acquisitions by the Company and thereafter such
             Person shall become the Beneficial Owner of any additional
             shares of Common Stock, then such Person shall be deemed to be
             an "Acquiring Person" (i) unless upon the consummation of the
             acquisition of such additional shares of Common Stock such
             Person does not own 20% or more of the shares of Common Stock
             then outstanding or (ii) the proviso to the first sentence of
             this Section 1(a) is applicable.  The phrase "then
             outstanding", when used with reference to a Person's
             Beneficial Ownership of securities of the Company, shall mean
             the number of such securities then issued and outstanding
             together with the number of such securities not then actually
             issued and outstanding which such Person would be deemed to
             own beneficially hereunder.

                (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 Exchange Act as in effect on
             the date of this Agreement.

                (c)  A Person shall be deemed the "Beneficial Owner" of,
             shall be deemed to have "Beneficial Ownership" of and shall be
             deemed to "beneficially own" any securities:

                  (i)  which such Person or any of such Person's Affiliates
                or Associates is deemed to beneficially own, directly or
                indirectly, within the meaning of Rule 13d-3 of the General
                Rules and Regulations under the Exchange Act as in effect
                on the date of this Agreement;

                 (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 (other than customary agreements with and
                between underwriters and selling group members with respect
                to a bona fide public offering of securities), or upon the
                exercise of conversion rights, exchange rights, rights,
                warrants or options, or otherwise; provided, however, that
                                                   --------  -------
                a Person shall not be deemed the Beneficial Owner of, or to
                beneficially own, (x) securities tendered pursuant to a
                tender or exchange offer made by or on behalf of such
                Person or any of such Person's Affiliates or Associates
                until such tendered securities are accepted for purchase,
                (y) securities which such Person has a right to acquire on

                or consent solicitation made pursuant to, and in accordance

             limitation, in a fiduciary capacity, by an Exempt Person or by

          determined by action of the Board of Directors prior to such time
          as any Person becomes an Acquiring Person) after the date of the
          commencement by any Person (other than an Exempt Person) of, or
          of the first public announcement of the intention of such Person
          (other than an Exempt Person) to commence, a tender or exchange
          offer the consummation of which would result in any Person
          becoming the Beneficial Owner of shares of Common Stock
          aggregating 20% or more of the Common Stock then outstanding
          (including any such date which is after the date of this
          Agreement and prior to the issuance of the Rights; the earlier of
          such dates being herein referred to as the "Distribution Date"),
          (x) the Rights will be evidenced (subject to the provisions of
          Section 3(b) hereof) by the certificates for Common Stock
          registered in the names of the holders thereof and not by
          separate Right Certificates, and (y) the Rights will be
          transferable only in connection with the transfer of Common
          Stock.  As soon as practicable after the Distribution Date, the
          Company will prepare and execute, the Rights Agent will
          countersign, and the Company will send or cause to be sent (and
          the Rights Agent will, if requested, send) by first-class,
          insured, postage-prepaid mail, to each record holder of Common
          Stock as of the Close of Business on the Distribution Date (other
          than any Acquiring Person or any Associate or Affiliate of an
          Acquiring Person), at the address of such holder shown on the
          records of the Company, a Right Certificate, in substantially the
          form of Exhibit B hereto (a "Right Certificate"), evidencing one
          Right (subject to adjustment as provided herein) for each share
          of Common Stock so held.  As of the Distribution Date, the Rights
          will be evidenced solely by such Right Certificates.

                (b)  On the Record Date, or as soon as practicable
          thereafter, the Company will send a copy of a Summary of Rights
          to Purchase Shares of Preferred Stock, in substantially the form
          of Exhibit C hereto (the "Summary of Rights"), by first-class,
          postage-prepaid mail, to each record holder of Common Stock as of
          the Close of Business on the Record Date (other than any
          Acquiring Person or any Associate or Affiliate of any Acquiring
          Person), at the address of such holder shown on the records of
          the Company.  With respect to certificates for Common Stock
          outstanding as of the Record Date, until the Distribution Date,
          the Rights will be evidenced by such certificates registered in
          the names of the holders thereof together with the Summary of
          Rights.  Until the Distribution Date (or, if earlier, the
          Expiration Date), the surrender for transfer of any certificate
          for Common Stock outstanding as of the Record Date, with or
          without a copy of the Summary of Rights, shall also constitute
          the transfer of the Rights associated with the Common Stock
          represented thereby.

                (c)  Certificates issued for Common Stock (including,
          without limitation, upon transfer of outstanding Common Stock,
          disposition of Common Stock out of treasury stock or issuance or
          reissuance of Common Stock out of authorized but unissued shares)
          after the Record Date but prior to the earlier of the
          Distribution Date or the Expiration Date shall have impressed on,
          printed on, written on or otherwise affixed to them the following
          legend:

                This certificate also evidences and entitles the
                holder hereof to certain rights as set forth in a
                Rights Agreement between Frontier Corporation and The
                First National Bank of Boston, as Rights Agent, dated
                as of April 9, 1995, as the same may be amended from
                time to time (the "Rights Agreement"), the terms of
                which are hereby incorporated herein by reference and
                a copy of which is on file at the principal executive
                offices of Frontier Corporation.  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.  Frontier Corporation 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, as
                                   -------------------------------
                set forth in the Rights Agreement, Rights owned by or
                -----------------------------------------------------
                transferred to any Person who becomes an Acquiring
                --------------------------------------------------
                Person (as defined in the Rights Agreement) and
                -----------------------------------------------
                certain transferees thereof will become null and void
                -----------------------------------------------------
                and will no longer be transferable.
                -----------------------------------

          With respect to such certificates containing the foregoing
          legend, until the Distribution Date, the Rights associated with
          the Common Stock represented by such certificates shall be
          evidenced by such certificates alone, and the surrender for 

          
                   

                                         -7-


<PAGE>
          transfer of any such certificate, except as otherwise provided
          herein, shall also constitute the transfer of the Rights
          associated with the Common Stock represented thereby.  In the
          event that the Company purchases or otherwise acquires any Common
          Stock after the Record Date but prior to the Distribution Date,
          any Rights associated with such Common Stock shall be deemed
          cancelled and retired so that the Company shall not be entitled
          to exercise any Rights associated with the Common Stock which are
          no longer outstanding.  

                Notwithstanding this paragraph (c), the omission of a
          legend shall not affect the enforceability of any part of this
          Agreement or the rights of any holder of the Rights.

                Section 4.  Form of Right Certificates.  The Right
                            --------------------------
          Certificates (and the forms of election to purchase shares and of
          assignment to be printed on the reverse thereof) shall be
          substantially in the form set forth in Exhibit B hereto and may
          have such marks of identification or designation and such
          legends, summaries or endorsements printed thereon as the 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 the New York
          Stock Exchange or of any other stock exchange or any quotation
          system on which the Rights may from time to time be listed, or to
          conform to usage.  Subject to the provisions of Sections 11 and
          22 hereof, the Right Certificates shall entitle the holders
          thereof to purchase such number of one one-hundredths of a share
          of Preferred Stock as shall be set forth therein at the price per
          one one-hundredth of a share of Preferred Stock set forth therein
          (the "Purchase Price"), but the number of such one one-hundredths
          of a share of Preferred Stock and the Purchase Price shall be
          subject to adjustment as provided herein.

                Section 5.  Countersignature and Registration.  (a)  The
                            ---------------------------------
          Right Certificates shall be executed on behalf of the Company by
          the Chairman of the Board of Directors, the President or a Vice
          President, and by the Secretary, an Assistant Secretary, the
          Treasurer or an Assistant Treasurer of the Company, in each case
          either manually or by facsimile signature, and shall have affixed
          thereto the Company's seal or a facsimile thereof.  The Right
          Certificates shall be manually countersigned by the Rights Agent
          and shall not be valid for any purpose unless so countersigned. 
          In case any officer of the Company who shall have signed any of
          the 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 Right Certificates, neverthe-
          less, 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 Agreement any such
          Person was not such an officer.

                (b)  Following the Distribution Date, the Rights Agent will
          keep or cause to be kept, at an office or agency designated for
          such purpose, 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.  (a)  Subject to the provisions of Sections 7(e),
          ------------
          11(a)(ii) and 14 hereof, at any time after the Close of Business
          on the Distribution Date and prior to the Close of Business on
          the 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 share
          of Preferred Stock 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 office or
          agency of the Rights Agent designated for such purpose. 
          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.

                (b)  Subject to the provisions of Section 11(a)(ii) hereof,
          at any time after the Distribution Date and prior to the Close of
          Business on the Expiration Date, 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 Certifi-
          cate, 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.

          "Expiration Date") that is the earliest of (i) the Close of

          23 hereof (the "Redemption Date") or (iii) the time at which such
          Rights are exchanged as provided in Section 24 hereof.

                (b)  The Purchase Price shall be initially $80 for each one
          one-hundredth of a share of Preferred Stock purchasable upon the
          exercise of a Right.  The Purchase Price and the number of one
          one-hundredths of a share of Preferred Stock or other securities
          or property to be acquired upon exercise of a Right shall be

                (c)  Except as otherwise provided herein, upon receipt of a
          Right Certificate representing exercisable Rights, with the form
          of election to purchase duly executed, accompanied by payment of
          the aggregate Purchase Price for the shares of Preferred Stock to

          accordance with Section 9 hereof, in cash or by certified check,
          cashier's check or money order payable to the order of the

          requisition from any transfer agent of the Preferred Stock
          certificates for the number of shares of Preferred Stock to be

          certificates for the Preferred Stock represented by such receipts
          shall be deposited by the transfer agent with the depositary
          agent) and the Company hereby directs the depositary agent to

          registered holder of any Right Certificate shall exercise less
          than all the Rights evidenced thereby, a new Right Certificate
          evidencing Rights equivalent to the exercisable Rights remaining

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

                (b)  So long as the shares of Preferred Stock (and,
          following the time that a Person becomes an Acquiring Person,
          shares of Common Stock and other securities) issuable upon the 




                                         -11-


<PAGE>
          exercise of Rights may be listed or admitted to trading on the
          New York Stock Exchange or listed on any other national
          securities exchange or quotation system, the Company shall use
          its best efforts to cause, from and after such time as the Rights
          become exercisable, all shares reserved for such issuance to be
          listed or admitted to trading on the New York Stock Exchange or
          listed on any other exchange or quotation system upon official
          notice of issuance upon such exercise.

                (c)  From and after such time as the Rights become
          exercisable, the Company shall use its best efforts, if then
          necessary to permit the issuance of shares of Preferred Stock
          (and following the time that a Person first becomes an Acquiring
          Person, shares of Common Stock and other securities) upon the
          exercise of Rights, to register and qualify such shares of
          Preferred Stock (and following the time that a Person first
          becomes an Acquiring Person, shares of Common Stock and other
          securities) under the Securities Act and any applicable state
          securities or "Blue Sky" laws (to the extent exemptions therefrom
          are not available), cause such registration statement and
          qualifications to become effective as soon as possible after such
          filing and keep such registration and qualifications effective
          until the earlier of the date as of which the Rights are no
          longer exercisable for such securities and the Expiration Date. 
          The Company may temporarily suspend, for a period of time not to
          exceed 90 days, the exercisability of the Rights in order to
          prepare and file a registration statement under the Securities
          Act and permit it to become effective.  Upon any such suspension,
          the Company shall issue a public announcement stating that the
          exercisability of the Rights has been temporarily suspended, as
          well as a public announcement at such time as the suspension is
          no longer in effect.  Notwithstanding any provision of this
          Agreement to the contrary, the Rights shall not be exercisable in
          any jurisdiction unless the requisite qualification in such
          jurisdiction shall have been obtained and until a registration
          statement under the Securities Act (if required) shall have been
          declared effective.

                (d)  The Company covenants and agrees that it will take all
          such action as may be necessary to ensure that all shares of
          Preferred Stock (and, following the time that a Person becomes an
          Acquiring Person, shares of Common Stock and other securities)
          delivered upon exercise of Rights shall, at the time of delivery
          of the certificates therefor (subject to payment of the Purchase
          Price), be duly and validly authorized and issued and fully paid
          and nonassessable shares.

                (e)  The Company further covenants and agrees that it will
          pay when due and payable any and all federal and state transfer
          taxes and charges which may be payable in respect of the issuance
          or delivery of the Right Certificates or of any shares of
          Preferred Stock (or shares of Common Stock or other securities)
          upon the exercise of Rights.  The Company shall not, however, be
          required to pay any transfer tax which may be payable in respect 




                                         -12-


<PAGE>
          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 Stock (or shares of Common
          Stock or other securities) in a name other than that of, the
          registered holder of the Right Certificate evidencing Rights
          surrendered for exercise or to issue or deliver any certificates
          or depositary receipts for Preferred Stock (or shares of Common
          Stock or other securities) upon the exercise of any Rights until
          any such tax shall have been paid (any such tax being payable by
          that holder of such Right Certificate at the time of surrender)
          or until it has been established to the Company's reasonable
          satisfaction that no such tax is due.

                Section 10.  Preferred Stock Record Date.  Each Person in
                             ---------------------------
          whose name any certificate for Preferred Stock is issued upon the
          exercise of Rights shall for all purposes be deemed to have
          become the holder of record of the shares of Preferred Stock
          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 Stock transfer books of the Company are closed, such
          Person shall be deemed to have become the record holder of such
          shares on, and such certificate shall be dated, the next
          succeeding Business Day on which the Preferred Stock 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 Stock for
          which the Rights shall be exercisable, including, without
          limitation, the right to vote or to receive dividends or other
          distributions, 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
                             ----------------------------------------------
          and Number of Rights.  The Purchase Price, the number of shares
          --------------------
          of Preferred Stock or other securities or property purchasable
          upon exercise of each Right and the number of Rights outstanding
          are subject to adjustment from time to time as provided in this
          Section 11.

                (a)  (i)  In the event the Company shall at any time after
             the date of this Agreement (A) declare a dividend on the
             Preferred Stock payable in shares of Preferred Stock, (B)
             subdivide the outstanding Preferred Stock, (C) combine the
             outstanding Preferred Stock into a smaller number of shares of
             Preferred Stock or (D) issue any shares of its capital stock
             in a reclassification of the Preferred Stock (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 




                                         -13-


<PAGE>
             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 Stock transfer
             books of the Company were open, the holder would have owned
             upon such exercise and been entitled to receive by virtue of
             such dividend, subdivision, combination or reclassification;
             provided, however, that in no event shall the consideration to
             --------  -------
             be paid upon the exercise of one Right be less than the
             aggregate par value of the shares of capital stock of the
             Company issuable upon exercise of one Right.

             (ii)  Subject to Section 24 of this Agreement and except as
             otherwise provided in this Section 11(a)(ii), in the event any
             Person becomes an Acquiring Person, each holder of a Right
             shall thereafter have the right to receive, upon exercise
             thereof at a price equal to the then current Purchase Price
             multiplied by the number of one one-hundredths of a share of
             Preferred Stock for which a Right is then exercisable, in
             accordance with the terms of this Agreement and in lieu of
             shares of Preferred Stock, such number of shares of Common
             Stock (or at the option of the Company, such number of one
             one-hundredths of shares of Preferred Stock) as shall equal
             the result obtained by (x) multiplying the then current
             Purchase Price by the number of one one-hundredths of a share
             of Preferred Stock for which a Right is then exercisable and
             dividing that product by (y) 50% of the then Current Per Share
             Market Price of the Company's Common Stock (determined
             pursuant to Section 11(d) hereof) on the date of the occur-
             rence of such event.  Notwithstanding anything in this
             Agreement to the contrary, however, from and after the time
             (the "Invalidation Time") when any Person first becomes an
             Acquiring Person, any Rights that are beneficially owned by
             (x) any Acquiring Person (or any Affiliate or Associate of any
             Acquiring Person), (y) a transferee of any Acquiring Person
             (or any such Affiliate or Associate) who becomes a transferee
             after the Invalidation Time or (z) a transferee of any
             Acquiring Person (or any such Affiliate or Associate) who
             became a transferee prior to or concurrently with the
             Invalidation Time pursuant to either (I) a transfer from the
             Acquiring Person to holders of its equity securities or to any
             Person with whom it has any continuing agreement, arrangement
             or understanding regarding the transferred Rights or (II) a
             transfer which the Board of Directors has determined is part
             of a plan, arrangement or understanding which has the purpose
             or effect of avoiding the provisions of this paragraph, and
             subsequent transferees of such Persons, shall be void without
             any further action and any holder of such Rights shall
             thereafter have no rights whatsoever with respect to such
             Rights under any provision of this Agreement.  The Company
             shall use all reasonable efforts to ensure that the provisions
             of this Section 11(a)(ii) are complied with, but shall have no




                                         -14-


<PAGE>
             liability to any holder of Right Certificates or other Person
             as a result of its failure to make any determinations with
             respect to an Acquiring Person or its Affiliates, Associates
             or transferees hereunder.  From and after the Invalidation
             Time, no Right Certificate shall be issued pursuant to Section
             3 or Section 6 hereof that represents Rights that are or have
             become void pursuant to the provisions of this paragraph, and
             any Right Certificate delivered to the Rights Agent that
             represents Rights that are or have become void pursuant to the
             provisions of this paragraph shall be cancelled.  From and
             after the occurrence of an event specified in Section 13(a)
             hereof, any Rights that theretofore have not been exercised
             pursuant to this Section 11(a)(ii) shall thereafter be
             exercisable only in accordance with Section 13 and not
             pursuant to this Section 11(a)(ii).

            (iii)  The Company may at its option substitute for a share of
             Common Stock issuable upon the exercise of Rights in
             accordance with the foregoing subparagraph (ii) such number or
             fractions of shares of Preferred Stock having an aggregate
             current market value equal to the Current Per Share Market
             Price of a share of Common Stock.  In the event that there
             shall not be sufficient shares of Common Stock issued but not
             outstanding or authorized but unissued to permit the exercise
             in full of the Rights in accordance with the foregoing
             subparagraph (ii), the Board of Directors shall, to the extent
             permitted by applicable law and any material agreements then
             in effect to which the Company is a party (A) determine the
             excess of (1) the value of the shares of Common Stock issuable
             upon the exercise of a Right in accordance with the foregoing
             subparagraph (ii) (the "Current Value") over (2) the then
             current Purchase Price multiplied by the number of one one-
             hundredths of shares of Preferred Stock for which a Right was
             exercisable immediately prior to the time that the Acquiring
             Person became such (such excess, the "Spread"), and (B) with
             respect to each Right (other than Rights which have become
             void pursuant to Section 11(a)(ii)), make adequate provision
             to substitute for the shares of Common Stock issuable in
             accordance with subparagraph (ii) upon exercise of the Right
             and payment of the applicable Purchase Price, (1) cash, (2) a
             reduction in the Purchase Price, (3) shares of Preferred Stock
             or other equity securities of the Company (including, without
             limitation, shares or fractions of shares of preferred stock
             which, by virtue of having dividend, voting and liquidation
             rights substantially comparable to those of the shares of
             Common Stock, are deemed in good faith by the Board of
             Directors to have substantially the same value as the shares
             of Common Stock (such shares of Preferred Stock and shares or
             fractions of shares of preferred stock are hereinafter
             referred to as "Common Stock Equivalents")), (4) debt
             securities of the Company, (5) other assets, or (6) any
             combination of the foregoing, having a value which, when added
             to the value of the shares of Common Stock actually issued
             upon exercise of such Right, shall have an aggregate value 




                                         -15-


<PAGE>
             equal to the Current Value (less the amount of any reduction
             in the Purchase Price), where such aggregate value has been
             determined by the Board of Directors upon the advice of a
             nationally recognized investment banking firm selected in good
             faith by the Board of Directors; provided, however, if the
                                              --------  -------
             Company shall not make adequate provision to deliver value
             pursuant to clause (B) above within thirty (30) days following
             the date that the Acquiring Person became such (the "Section
             11(a)(ii) Trigger Date"), then the Company shall be obligated
             to deliver, to the extent permitted by applicable law and any
             material agreements then in effect to which the Company is a
             party, upon the surrender for exercise of a Right and without
             requiring payment of the Purchase Price, shares of Common
             Stock (to the extent available), and then, if necessary, such
             number or fractions of shares of Preferred Stock (to the
             extent available) and then, if necessary, cash, which shares
             and/or cash have an aggregate value equal to the Spread.  If,
             upon the date any Person becomes an Acquiring Person, the
             Board of Directors shall determine in good faith that it is
             likely that sufficient additional shares of Common Stock could
             be authorized for issuance upon exercise in full of the
             Rights, then, if the Board of Directors so elects, the thirty
             (30) day period set forth above may be extended to the extent
             necessary, but not more than ninety (90) days after the
             Section 11(a)(ii) Trigger Date, in order that the Company may
             seek shareowner approval for the authorization of such
             additional shares (such thirty (30) day period, as it may be
             extended, is herein called the "Substitution Period").  To the
             extent that the Company determines that some action need be
             taken pursuant to the second and/or third sentence of this
             Section 11(a)(iii), the Company (x) shall provide, subject to
             Section 11(a)(ii) hereof and the last sentence of this Section
             11(a)(iii) hereof, that such action shall apply uniformly to
             all outstanding Rights and (y) may suspend the exercisability
             of the Rights until the expiration of the Substitution Period
             in order to seek any authorization of additional shares and/or
             to decide the appropriate form of distribution to be made
             pursuant to such second sentence and to determine the value
             thereof.  In the event of any such suspension, the Company
             shall issue a public announcement stating that the
             exercisability of the Rights has been temporarily suspended,
             as well as a public announcement at such time as the
             suspension is no longer in effect.  For purposes of this
             Section 11(a)(iii), the value of the shares of Common Stock
             shall be the Current Per Share Market Price (as determined
             pursuant to Section 11(d)(i)) on the Section 11(a)(ii) Trigger
             Date and the per share or fractional value of any "Common
             Stock Equivalent" shall be deemed to equal the Current Per
             Share Market Price of the Common Stock.  The Board of
             Directors of the Company may, but shall not be required to,
             establish procedures to allocate the right to receive shares
             of Common Stock upon the exercise of the Rights among holders
             of Rights pursuant to this Section 11(a)(iii).

                (b)  In case the Company shall fix a record date for the
             issuance of rights, options or warrants to all holders of
             Preferred Stock entitling them (for a period expiring within
             45 calendar days after such record date) to subscribe for or
             purchase Preferred Stock (or shares having the same rights,
             privileges and preferences as the Preferred Stock ("Equivalent
             Preferred Shares")) or securities convertible into Preferred
             Stock or Equivalent Preferred Shares at a price per share of
             Preferred Stock or Equivalent Preferred Shares (or having a
             conversion price per share, if a security convertible into
             shares of Preferred Stock or Equivalent Preferred Shares) less
             than the then Current Per Share Market Price of the Preferred
             Stock (determined pursuant to Section 11(d) hereof) on such
             record date, the Purchase Price to be in effect after such
             record date shall be determined by multiplying the Purchase
             Price in effect immediately prior to such record date by a
             fraction, the numerator of which shall be the number of shares
             of Preferred Stock and Equivalent Preferred Shares outstanding
             on such record date plus the number of shares of Preferred
             Stock and Equivalent Preferred Shares which the aggregate
             offering price of the total number of shares of Preferred
             Stock and/or Equivalent Preferred Shares so to be offered
             (and/or the aggregate initial conversion price of the con-
             vertible securities so to be offered) would purchase at such
             current market price, and the denominator of which shall be
             the number of shares of Preferred Stock and Equivalent
             Preferred Shares outstanding on such record date plus the
             number of additional shares of Preferred Stock and/or
             Equivalent Preferred Shares to be offered for subscription or
             purchase (or into which the convertible securities so to be
             offered are initially convertible); provided, however, that in
                                                 --------  -------
             no event shall the consideration to be paid upon the exercise
             of one Right be less than the aggregate par value of the
             shares of capital stock of the Company issuable upon exercise
             of one Right.  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.  Shares of Preferred Stock and
             Equivalent 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, options or warrants are not so issued,
             the Purchase Price shall be adjusted to be the Purchase Price
             which would then be in effect if such record date had not been
             fixed.

                (c)  In case the Company shall fix a record date for the
             making of a distribution to all holders of the Preferred Stock
             (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 Stock) or subscription rights or
             warrants (excluding those referred to in Section 11(b)
             hereof), the Purchase Price to be in effect after such record
             date shall be determined by multiplying the Purchase Price in
             effect immediately prior to such record date by a fraction,
             the numerator of which shall be the then Current Per Share
             Market Price of the Preferred Stock (determined pursuant to
             Section 11(d) hereof) 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 share of Preferred Stock, and the
             denominator of which shall be such Current Per Share Market
             Price (determined pursuant to Section 11(d) hereof) of the
             Preferred Stock; provided, however, that in no event shall the
                              --------  -------
             consideration to be paid upon the exercise of one Right be
             less than the aggregate par value of the shares of capital
             stock of the Company to be issued upon exercise of one Right. 
             Such adjustments shall be made successively whenever such a
             record date is fixed; and in the event that such distribution
             is not so made, the Purchase Price shall again be adjusted to
             be the Purchase Price which would then be in effect if such
             record date had not been fixed.

                (d) (i)  Except as otherwise provided herein, for the
             purpose of any computation hereunder, the "Current Per Share
             Market Price" of any security (a "Security" for the purpose of
             this Section 11(d)(i)) on any date shall be deemed to be the
             average of the daily closing prices per share of such Security
             for the 30 consecutive Trading Days (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 Security is determined during a period following
             the announcement by the issuer of such Security of (A) a
             dividend or distribution on such Security payable in shares of
             such Security or securities convertible into such shares, or
             (B) any subdivision, combination or reclassification of such
             Security, and prior to the expiration of 30 Trading Days after
             the ex-dividend date for such dividend or distribution, or the
             record date for such subdivision, combination or
             reclassification, then, and in each such case, the Current Per
             Share Market Price shall be appropriately adjusted to reflect
             the current market price per share equivalent of such
             Security.  The closing price for each day shall be the last
             sale price, regular way, or, in case no such sale takes place
             on such day, the average of the closing bid and asked prices,
             regular way, in either case as reported by the principal
             consolidated transaction reporting system with respect to
             securities listed or admitted to trading on the New York Stock
             Exchange or, if the Security is not listed or admitted to
             trading on the New York Stock Exchange, as reported in the 




                                         -18-


<PAGE>
             principal consolidated transaction reporting system with
             respect to securities listed on the principal national
             securities exchange on which the Security is listed or
             admitted to trading or, if the Security is not listed or
             admitted to trading on any national securities exchange, the
             last quoted price or, if not so quoted, the average of the
             high bid and low asked prices in the over-the-counter market,
             as reported by NASDAQ or such other system then in use, or, if
             on any such date the Security is not quoted by any such
             organization, the average of the closing bid and asked prices
             as furnished by a professional market maker making a market in
             the Security selected by the Board of Directors of the
             Company.  The term "Trading Day" shall mean a day on which the
             principal national securities exchange on which the Security
             is listed or admitted to trading is open for the transaction
             of business or, if the Security is not listed or admitted to
             trading on any national securities exchange, a Business Day.

                (ii)  For the purpose of any computation hereunder, if the
             Preferred Stock is publicly traded, the "Current Per Share
             Market Price" of the Preferred Stock shall be determined in
             accordance with the method set forth in Section 11(d)(i).  If
             the Preferred Stock is not publicly traded but the Common
             Stock is publicly traded, the "Current Per Share Market Price"
             of the Preferred Stock shall be conclusively deemed to be the
             Current Per Share Market Price of the Common Stock as deter-
             mined pursuant to Section 11(d)(i) multiplied by one hundred
             (appropriately adjusted to reflect any stock split, stock
             dividend or similar transaction occurring after the date
             hereof).  If neither the Common Stock nor the Preferred Stock
             is publicly 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 taken into
             account in any subsequent adjustment.  All calculations under
             this Section 11 shall be made to the nearest cent or to the
             nearest one ten-thousandth of a share of Preferred Stock or
             share of Common Stock or other share or security as the case
             may be.  Notwithstanding the first sentence of this Section
             11(e), any adjustment required by this Section 11 shall be
             made no later than the earlier of (i) three years from the
             date of the transaction which requires such adjustment or (ii)
             the Expiration Date.

                (f)  If as a result of an adjustment made pursuant to
             Section 11(a) hereof, the holder of any Right thereafter
             exercised shall become entitled to receive any shares of cap-
             ital stock of the Company other than the Preferred Stock, 




                                         -19-


<PAGE>
             thereafter the number of such other shares so receivable upon
             exercise of a 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
             Stock contained in Sections 11(a), 11(b), 11(c), 11(e), 11(h),
             11(i) and 11(m), and the provisions of Sections 7, 9, 10, 13
             and 14 hereof with respect to the Preferred Stock shall apply
             on like terms to any such other shares.

                (g)  All Rights originally issued by the Company subsequent
             to any adjustment made to the Purchase Price hereunder shall
             evidence the right to purchase, at the adjusted Purchase
             Price, the number of one one-hundredths of a share of Prefer-
             red Stock purchasable from time to time hereunder upon exer-
             cise of the Rights, all subject to further adjustment as pro-
             vided herein.

                (h)  Unless the Company shall have exercised its election
             as provided in Section 11(i), upon each adjustment of the
             Purchase Price as a result of the calculations made in
             Sections 11(b) and (c), each Right outstanding immediately
             prior to the making of such adjustment shall thereafter evi-
             dence the right to purchase, at the adjusted Purchase Price,
             that number of one one-hundredths of a share of Preferred
             Stock (calculated to the nearest one ten- thousandth of a
             share of Preferred Stock) obtained by (i) multiplying (x) the
             number of one one-hundredths of a share covered by a Right
             immediately prior to such 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 share of Preferred Stock 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 share of
             Preferred Stock for which a Right was exercisable immediately
             prior to such adjustment.  Each Right held of record prior to
             such adjustment of the number of Rights shall become that
             number of Rights (calculated to the nearest one
             ten-thousandth) obtained by dividing the Purchase Price in
             effect immediately prior to adjustment of the Purchase Price
             by the Purchase Price in effect immediately after adjustment
             of the Purchase Price.  The Company shall make a public
             announcement of its election to adjust the number of Rights,
             indicating the record date for the adjustment, and, if known
             at the time, the amount of the adjustment 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 




                                         -20-


<PAGE>
             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 may, 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 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 share
             of Preferred Stock 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 share of Preferred Stock 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 the then par
             value, if any, of the Preferred Stock or other shares of
             capital stock issuable upon exercise of the Rights, the
             Company shall take any corporate action which may, in the
             opinion of its counsel, be necessary in order that the Company
             may validly and legally issue fully paid and nonassessable
             shares of Preferred Stock or other such 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 Stock and other capital stock or securities of the
             Company, if any, issuable upon such exercise over and above
             the Preferred Stock and other capital stock or securities of
             the Company, if any, issuable upon such exercise on the basis
             of the Purchase Price in effect prior to such adjustment;
             provided, however, that the Company shall deliver to such
             --------  -------
             holder a due bill or other appropriate instrument evidencing
             such holder's right to receive such additional shares 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 




                                         -21-


<PAGE>
             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 Stock, issuance wholly for cash of any shares of
             Preferred Stock at less than the current market price,
             issuance wholly for cash or Preferred Stock or securities
             which by their terms are convertible into or exchangeable for
             Preferred Stock, dividends on Preferred Stock payable in
             shares of Preferred Stock or issuance of rights, options or
             warrants referred to hereinabove in Section 11(b), hereafter
             made by the Company to holders of its Preferred Stock shall
             not be taxable to such shareowners.

                (n)  Anything in this Agreement to the contrary
             notwithstanding, in the event that at any time after the date
             of this Agreement and prior to the Distribution Date, the
             Company shall (i) declare or pay any dividend on the Common
             Stock payable in Common Stock or (ii) effect a subdivision,
             combination or consolidation of the Common Stock (by reclas-
             sification or otherwise than by payment of a dividend payable
             in Common Stock) into a greater or lesser number of Common
             Stock, then in any such case, the number of Rights associated
             with each share of Common Stock then outstanding, or issued or
             delivered thereafter, shall be proportionately adjusted so
             that the number of Rights thereafter associated with each
             share of Common Stock following any such event shall equal the
             result obtained by multiplying the number of Rights associated
             with each share of Common Stock immediately prior to such
             event by a fraction the numerator of which shall be the total
             number of shares of Common Stock outstanding immediately prior
             to the occurrence of the event and the denominator of which
             shall be the total number of shares of Common Stock
             outstanding immediately following the occurrence of such
             event.

                (o)  The Company agrees that, after the earlier of the
             Distribution Date or the Stock Acquisition Date, it will not,
             except as permitted by Sections 23, 24 or 27 hereof, take (or
             permit any Subsidiary to take) any action if at the time such
             action is taken it is reasonably foreseeable that such action
             will diminish substantially or eliminate the benefits intended
             to be afforded by the Rights.

          Number of Shares.  Whenever an adjustment is made as provided in

          Rights Agent and with each transfer agent for the Common Stock or

                             --------------------------------------------
          Assets or Earnings Power.  (a)  In the event, directly or
          ------------------------
          indirectly, at any time after any Person has become an Acquiring
          Person, (i) the Company shall merge with and into any other
          Person, (ii) any Person shall consolidate with the Company, or
          any Person shall 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
          Stock shall be changed into or exchanged for stock or other
          securities of any other Person (or of the Company) or cash or any
          other property, or (iii) 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 upon the first occurrence of
          such event, proper provision shall be made so that: (A) each
          holder of record of a Right (other than Rights which have become
          void pursuant to Section 11(a)(ii)) shall thereafter have the
          right to receive, upon the exercise thereof at a price equal to
          the then current Purchase Price multiplied by the number of one
          one-hundredths of a share of Preferred Stock for which a Right
          was exercisable immediately prior to the time that any Person
          first became an Acquiring Person (as subsequently adjusted
          thereafter pursuant to Sections 11(a)(i), 11(b), 11(c) and
          11(i)), in accordance with the terms of this Agreement and in
          lieu of Preferred Stock, such number of validly issued, fully
          paid and non-assessable and freely tradeable shares of Common
          Stock of the Principal Party (as defined herein) not subject to
          any liens, encumbrances, rights of first refusal or other adverse
          claims, as shall be equal to the result obtained by (1)
          multiplying the then current Purchase Price by the number of one
          one-hundredths of a share of Preferred Stock for which a Right
          was exercisable immediately prior to the time that any Person
          first became an Acquiring Person (as subsequently adjusted
          thereafter pursuant to Sections 11(a)(i), 11(b), 11(c) and 11(i))
          and (2) dividing that product by 50% of the then Current Per
          Share Market Price of the Common Stock of such Principal Party
          (determined pursuant to Section 11(d)(i) hereof) on the date of
          consummation of such consolidation, merger, sale or transfer;
          provided that the Purchase Price and the number of shares of
          --------
          Common Stock of such Principal Party issuable upon exercise of
          each Right shall be further adjusted as provided in Section 11(f)
          of this Agreement to reflect any events occurring in respect of
          such Principal Party after the occurrence of such consolidation,
          merger, sale or transfer; (B) such Principal Party 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; (C) the term 




                                         -23-

          "Company" shall thereafter be deemed to refer to such Principal
          Party; and (D) such Principal Party shall take such steps
          (including, but not limited to, the reservation of a sufficient
          number of its shares of Common Stock in accordance with Section 9
          hereof) in connection with such consummation of any such
          transaction as may be necessary to assure that the provisions
          hereof shall thereafter be applicable, as nearly as reasonably
          may be, in relation to the shares of its Common Stock thereafter
          deliverable upon the exercise of the Rights; provided that, upon
          the subsequent occurrence of any consolidation, merger, sale or
          transfer of assets or other extraordinary transaction in respect
          of such Principal Party, each holder of a Right shall thereupon
          be entitled to receive, upon exercise of a Right and payment of
          the Purchase Price as provided in this Section 13(a), such cash,
          shares, rights, warrants and other property which such holder
          would have been entitled to receive had such holder, at the time
          of such transaction, owned the Common Stock of the Principal
          Party receivable upon the exercise of a Right pursuant to this
          Section 13(a), and such Principal Party shall take such steps
          (including, but not limited to, reservation of shares of stock)
          as may be necessary to permit the subsequent exercise of the
          Rights in accordance with the terms hereof for such cash, shares,
          rights, warrants and other property.

                (b)  "Principal Party" shall mean:

              (i)  in the case of any transaction described in (i) or (ii)
             of the first sentence of Section 13(a) hereof:  (A) the Person
             that is the issuer of the securities into which the shares of
             Common Stock are converted in such merger or consolidation,
             or, if there is more than one such issuer, the issuer the
             shares of Common Stock of which have the greatest aggregate
             market value of shares outstanding, or (B) if no securities
             are so issued, (x) the Person that is the other party to the
             merger, if such Person survives said merger, or, if there is
             more than one such Person, the Person the shares of Common
             Stock of which have the greatest aggregate market value of
             shares outstanding or (y) if the Person that is the other
             party to the merger does not survive the merger, the Person
             that does survive the merger (including the Company if it
             survives) or (z) the Person resulting from the consolidation;
             and 

             (ii)  in the case of any transaction described in (iii) of the
             first sentence in Section 13(a) hereof, the Person that is the
             party receiving the greatest portion of the assets or earning
             power transferred pursuant to such transaction or
             transactions, or, if each Person that is a party to such
             transaction or transactions receives the same portion of the
             assets or earning power so transferred or if the Person
             receiving the greatest portion of the assets or earning power
             cannot be determined, whichever of such Persons as is the
             issuer of Common Stock having the greatest aggregate market
             value of shares outstanding;




                                         -24-


<PAGE>
          provided, however, that in any such case described in the
          foregoing clause (b)(i) or (b)(ii), (1) if the Common Stock of
          such Person is not at such time or has not been continuously over
          the preceding 12-month period registered under Section 12 of the
          Exchange Act, and if such Person is a direct or indirect
          Subsidiary of another Person the Common Stock of which is and has
          been so registered, the term "Principal Party" shall refer to
          such other Person, or (2) if such Person is a Subsidiary,
          directly or indirectly, of more than one Person, the Common Stock
          of all of which is and has been so registered, the term
          "Principal Party" shall refer to whichever of such Persons is the
          issuer of Common Stock having the greatest aggregate market value
          of shares outstanding, or (3) if such Person is owned, directly
          or indirectly, by a joint venture formed by two or more Persons
          that are not owned, directly or indirectly, by the same Person,
          the rules set forth in clauses (1) and (2) above shall apply to
          each of the owners having an interest in the venture as if the
          Person owned by the joint venture was a Subsidiary of both or all
          of such joint venturers, and the Principal Party in each such
          case shall bear the obligations set forth in this Section 13 in
          the same ratio as its interest in such Person bears to the total
          of such interests.

                (c)  The Company shall not consummate any consolidation,
          merger, sale or transfer referred to in Section 13(a) hereof
          unless prior thereto the Company and the Principal Party involved
          therein shall have executed and delivered to the Rights Agent an
          agreement confirming that the requirements of Sections 13(a) and
          (b) hereof shall promptly be performed in accordance with their
          terms and that such consolidation, merger, sale or transfer of
          assets shall not result in a default by the Principal Party under
          this Agreement as the same shall have been assumed by the
          Principal Party pursuant to Sections 13(a) and (b) hereof and
          providing that, as soon as practicable after executing such
          agreement pursuant to this Section 13, the Principal Party will:

              (i)  prepare and file a registration statement under the
             Securities Act, if necessary, with respect to the Rights and
             the securities purchasable upon exercise of the Rights on an
             appropriate form, use its best efforts to cause such
             registration statement to become effective as soon as
             practicable after such filing and use its best efforts to
             cause such registration statement to remain effective (with a
             prospectus at all times meeting the requirements of the
             Securities Act) until the Expiration Date, and similarly
             comply with applicable state securities laws;

             (ii)  use its best efforts, if the Common Stock of the
             Principal Party shall be listed or admitted to trading on the
             New York Stock Exchange or on another national securities
             exchange, to list or admit to trading (or continue the listing
             of) the Rights and the securities purchasable upon exercise of
             the Rights on the New York Stock Exchange or such securities
             exchange, or, if the Common Stock of the Principal Party shall

<PAGE>
             not be listed or admitted to trading on the New York Stock
             Exchange or a national securities exchange, to cause the
             Rights and the securities receivable upon exercise of the
             Rights to be reported by such other system then in use;

            (iii)  deliver to holders of the Rights historical financial
             statements for the Principal Party which comply in all
             respects with the requirements for registration on Form 10 (or
             any successor form) under the Exchange Act; and

             (iv)  obtain waivers of any rights of first refusal or
             preemptive rights in respect of the Common Stock of the
             Principal Party subject to purchase upon exercise of
             outstanding Rights.

                (d)  In case the Principal Party has provision in any of
          its authorized securities or in its certificate of incorporation
          or by-laws or other instrument governing its corporate affairs,
          which provision would have the effect of (i) causing such
          Principal Party to issue (other than to holders of Rights
          pursuant to this Section 13), in connection with, or as a
          consequence of, the consummation of a transaction referred to in
          this Section 13, shares of Common Stock of such Principal Party
          at less than the then current market price per share thereof
          (determined pursuant to Section 11(d) hereof) or securities
          exercisable for, or convertible into, Common Stock of such
          Principal Party at less than such then current market price, or
          (ii) providing for any special payment, tax or similar provision
          in connection with the issuance of the Common Stock of such
          Principal Party pursuant to the provisions of Section 13, then,
          in such event, the Company hereby agrees with each holder of
          Rights that it shall not consummate any such transaction unless
          prior thereto the Company and such Principal Party shall have
          executed and delivered to the Rights Agent a supplemental
          agreement providing that the provision in question of such
          Principal Party shall have been cancelled, waived or amended, or
          that the authorized securities shall be redeemed, so that the
          applicable provision will have no effect in connection with, or
          as a consequence of, the consummation of the proposed
          transaction.

                (e)  The Company covenants and agrees that it shall not, at
          any time after a Person first becomes an Acquiring Person, enter
          into any transaction of the types contemplated by clauses (i)
          through (iii) of Section 13(a) hereof if (x) at the time of or
          immediately after such consolidation, merger, sale, transfer or
          other transaction there are any rights, warrants or other
          instruments or securities outstanding or agreements in effect
          which would substantially diminish or otherwise eliminate the
          benefits intended to be afforded by the Rights, (y) prior to,
          simultaneously with or immediately after such consolidation,
          merger, sale, transfer of other transaction, the stockholders of
          the Person who constitutes, or would constitute, the Principal
          Party for purposes of Section 13(a) hereof shall have received a

          distribution of Rights previously owned by such Person or any of
          its Affiliates or Associates or (z) the form or nature of
          organization of the Principal Party would preclude or limit the
          exercisability of the Rights.

                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.  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
          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 Stock (other than fractions which are integral
          multiples of one one-hundredth of a share of Preferred Stock)
          upon exercise of the Rights or to distribute certificates which
          evidence fractional shares of Preferred Stock (other than
          fractions which are integral multiples of one one-hundredth of a
          share of Preferred Stock).  Interests in fractions of Preferred
          Stock in integral multiples of one one-hundredth of a share of
          Preferred Stock 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 




                                         -27-


<PAGE>
          the Preferred Stock represented by such depositary receipts.  In
          lieu of fractional shares of Preferred Stock that are not
          integral multiples of one one-hundredth of a share of Preferred
          Stock, 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 share of Preferred Stock.  For the
          purposes of this Section 14(b), the current market value of a
          share of Preferred Stock shall be the closing price of a share of
          Preferred Stock (as determined pursuant to 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 Stock); and any registered holder of any Right Certificate
          (or, prior to the Distribution Date, of the Common Stock),
          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 Stock), on his own behalf and for his own benefit, may
          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 (or, prior to the Distribution Date, such
          Common Stock) in the manner provided in such Right Certificate
          and in this Agreement.  Without limiting the foregoing or any
          remedies available to the holders of Rights, it is specifically
          acknowledged that the holders of Rights would not have an
          adequate remedy at law for any breach of this Agreement and will
          be entitled to specific performance of the obligations under, and
          injunctive relief against actual or threatened violations of, the
          obligations of any Person subject to this Agreement.

                Section 16.  Agreement of Right Holders.  Every holder of a
                             --------------------------
          Right, by accepting the same, consents and agrees with the
          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 Stock;

                (b)  after the Distribution Date, the Right Certificates
             are transferable only on the registry books of the Rights
             Agent if surrendered at the office or agency of the Rights

             Agent designated for such purpose, 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 Common Stock certificate) is
             registered as the absolute owner thereof and of the Rights
             evidenced thereby (notwithstanding any notations of ownership
             or writing on the Right Certificates or the Common Stock
             certificate made by anyone other than the Company or the
             Rights Agent) for all purposes whatsoever, and neither the
             Company nor the Rights Agent shall be affected by any notice
             to the contrary.

          Stockholder.  No holder, as such, of any Right Certificate shall
          -----------
          be entitled to vote, receive dividends or be deemed for any
          purpose the holder of the Preferred Stock or any other securities
          of the Company which may at any time be issuable on the exercise
          of the Rights represented thereby, nor shall anything contained
          herein or in any Right Certificate be construed to confer upon
          the holder of any Right Certificate, as such, any of the rights
          of a stockholder of the Company or any right to vote for the
          election of directors or upon any matter submitted to
          stockholders at any meeting thereof, or to give or withhold
          consent to any corporate action, or to receive notice of meetings
          or other actions affecting stockholders (except as provided in

          or otherwise, until the Rights evidenced by such Right
          Certificate shall have been exercised in accordance with the
          provisions hereof.

                Section 18.  Concerning the Rights Agent.  (a)  The Company
                             ---------------------------
          agrees to pay to the Rights Agent reasonable compensation for all
          services rendered by it hereunder and, from time to time, on
          demand of the Rights Agent, its reasonable expenses and counsel
          fees and 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 administration of this Agreement, including the
          costs and expenses of defending against any claim of liability
          arising therefrom, directly or indirectly.

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

          believed by it to be genuine and to be signed, executed and,
          where necessary, verified or acknowledged, by the proper Person
          or Persons, or otherwise upon the advice of counsel as set forth
          in Section 20 hereof.

                Section 19.  Merger or Consolidation or Change of Name of
                             --------------------------------------------
          Rights Agent.  (a)  Any 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
          stock transfer or corporate trust powers of the Rights Agent or
          any successor Rights Agent, shall be the successor to the Rights
          Agent under this Agreement without the execution or filing of any
          paper or any further act on the part of any of the parties
          hereto; provided, that such corporation would be eligible for
                  --------
          appointment as a successor Rights Agent under the provisions of
          Section 21 hereof.  In case at the time such successor Rights
          Agent shall succeed to the agency created by this Agreement, any
          of the Right Certificates shall have been countersigned but not
          delivered, any such successor Rights Agent may adopt the
          countersignature of 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. 

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

                Section 20.  Duties of Rights Agent.  The Rights Agent
                             ----------------------
          undertakes the duties and obligations imposed by this Agreement
          upon the following terms and conditions, by all of 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 opin-
             ion.

<PAGE>
                (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 of Directors, the
             President, any Vice President, the Treasurer, the Controller
             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.

                (d)  The Rights Agent shall not be liable for or by reason
             of any of the statements of fact or recitals contained in this
             Agreement or in the Right Certificates (except its
             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 Sections 3,
             11, 13, 23 and 24, 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 receipt of a certificate furnished pursuant
             to Section 12, describing such change or adjustment); nor
             shall it by any act hereunder be deemed to make any
             representation or warranty as to the authorization or
             reservation of any shares of Preferred Stock or other
             securities to be issued pursuant to this Agreement or any
             Right Certificate or as to whether any shares of Preferred
             Stock or other securities 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,
             acknowledged and delivered all such further and other acts,

             instruments and assurances as may reasonably be required by
             the Rights Agent for the carrying out or performing by the
             Rights Agent of the provisions of this Agreement.

                (g)  The Rights Agent is hereby authorized and directed to
             accept instructions with respect to the performance of its
             duties hereunder from any person reasonably believed by the
             Rights Agent to be one of the Chairman of the Board of
             Directors, the President, a Vice President, the Treasurer or
             the Secretary 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.  Any application by the Rights Agent for written
             instructions from the Company may, at the option of the Rights
             Agent, set forth in writing any action proposed to be taken or
             omitted by the Rights Agent under this Agreement and the date
             on and/or after which such action shall be taken or such
             omission shall be effective.  The Rights Agent shall not be
             liable for any action taken by, or omission of, the Rights
             Agent in accordance with a proposal included in any such
             application on or after the date specified in such application
             (which date shall not be less than five Business Days after
             the date any officer of the Company actually receives such
             application, unless any such officer shall have consented in
             writing to an earlier date) unless, prior to taking any such
             action (or the effective date in the case of an omission), the
             Rights Agent shall have received written instructions in
             response to such application specifying the action to be taken
             or omitted. 

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

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

                (j)  If, with respect to any Rights Certificate surrendered
             to the Rights Agent for exercise or transfer, the certificate 




                                         -32-


<PAGE>
             contained in the form of assignment or the form of election to
             purchase set forth on the reverse thereof, as the case may be,
             has not been completed to certify the holder is not an
             Acquiring Person (or an Affiliate or Associate thereof), a
             Rights Agent shall not take any further action with respect to
             such requested exercise of transfer without first consulting
             with the Company.

                (k)  The Rights Agent's duties shall be determined only
             with reference to this Agreement and the Rights Agent shall
             not be charged with knowledge of or any duties or
             responsibilities in connection with any other document or
             agreement.

                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
          Stock or Preferred Stock by registered or certified mail, and,
          following the Distribution Date, 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
          Stock or Preferred Stock by registered or certified mail, and,
          following the Distribution Date, 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 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 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 or stock transfer powers
          and is subject to supervision or examination by federal or state
          authority and which has at the time of its appointment as Rights
          Agent a combined capital and surplus of at least $50 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 




                                         -33-


<PAGE>
          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 Stock or
          Preferred Stock, and, following the Distribution Date, mail a
          notice thereof in writing to the registered holders of the Right
          Certificates.  Failure to give any notice provided for in this
          Section 21, however, or any defect therein, shall not affect the
          legality or validity of the resignation or removal of the Rights
          Agent or the appointment of the successor Rights Agent, as the
          case may be.

                Section 22.  Issuance of New Right Certificates. 
                             ----------------------------------
          Notwithstanding any of the provisions of this Agreement or of the
          Rights to the contrary, the Company may, at its option, issue new
          Right Certificates evidencing Rights in such forms 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.  In addition, in connection with the issuance or sale
          of Common Stock following the Distribution Date and prior to the
          Expiration Date, the Company may with respect to shares of Common
          Stock so issued or sold pursuant to (i) the exercise of stock
          options, (ii) under any employee plan or arrangement, (iii) upon
          the exercise, conversion or exchange of securities notes or
          debentures issued by the Company or (iv) a contractual obligation
          of the Company in each case existing prior to the Distribution
          Date, issue Right Certificates representing the appropriate
          number of Rights in connection with such issuance or sale.

                Section 23.  Redemption.  (a)  The Board of Directors of
                             ----------
          the Company may, at any time prior to such time as any Person
          first becomes an Acquiring Person, redeem all but not less than
          all the then outstanding Rights at a redemption price of $.01 per
          Right, appropriately adjusted to reflect any stock split, stock
          dividend or similar transaction occurring after the date hereof
          (the redemption price being hereinafter referred to as the
          "Redemption Price").  The redemption of the Rights may be made
          effective at such time, on such basis and with such conditions as
          the Board of Directors in its sole discretion may establish.

                (b)  Immediately upon the action of the Board of Directors
          ordering the redemption of the Rights pursuant to paragraph (a)
          of this Section 23 (or at such later time as the Board of
          Directors may establish for the effectiveness of such
          redemption), 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.  The Company shall promptly give
          public notice of any such redemption; provided, however, that the
                                                --------  -------
          failure to give, or any defect in, any such notice shall not
          affect the validity of such redemption.  Within 10 days after
          such action of the Board of Directors ordering the redemption of 




                                         -34-


<PAGE>
          the Rights (or such later time as the Board of Directors may
          establish for the effectiveness of such redemption), the Company
          shall mail a notice of redemption to all the holders of the then
          outstanding Rights at their last addresses as they appear upon
          the registry books of the Rights Agent or, prior to the
          Distribution Date, on the registry books of the transfer agent
          for the Common Stock.  Any notice which is mailed in the manner
          herein provided shall be deemed given, whether or not the holder
          receives the notice.  Each such notice of redemption shall state
          the method by which the payment of the Redemption Price will be
          made.  

                Section 24.  Exchange.  (a)  The Board of Directors of the
                             --------
          Company may, at its option, at any time after any Person first
          becomes an Acquiring Person, exchange all or part of the then
          outstanding and exercisable Rights (which shall not include
          Rights that have become void pursuant to the provisions of
          Section 11(a)(ii) hereof) for shares of Common Stock at an
          exchange ratio of one share of Common Stock per Right, (such
          exchange ratio being hereinafter referred to as the "Exchange
          Ratio").  Notwithstanding the foregoing, the Board of Directors
          shall not be empowered to effect such exchange at any time after
          any Person (other than an Exempt Person), together with all
          Affiliates and Associates of such Person, becomes the Beneficial
          Owner of shares of Common Stock aggregating 50% or more of the
          shares of Common Stock then outstanding.

                (b)  Immediately upon the action of the Board of Directors
          of the Company ordering the exchange of any Rights pursuant to
          paragraph (a) of this Section 24 and without any further action
          and without any notice, the right to exercise such Rights shall
          terminate and the only right thereafter of a holder of such
          Rights shall be to receive that number of shares of Common Stock
          equal to the number of such Rights held by such holder multiplied
          by the Exchange Ratio.  The Company shall promptly give public
          notice of any such exchange; provided, however, that the failure
                                       --------  -------
          to give, or any defect in, such notice shall not affect the
          validity of such exchange.  The Company shall promptly mail a
          notice of any such exchange to all of the holders of the Rights
          so exchanged at their last addresses as they appear upon the
          registry books of the Rights Agent.  Any notice which is mailed
          in the manner herein provided shall be deemed given, whether or
          not the holder receives the notice.  Each such notice of exchange
          will state the method by which the exchange of the shares of
          Common Stock for Rights will be effected and, in the event of any
          partial exchange, the number of Rights which will be exchanged. 
          Any partial exchange shall be effected pro rata based on the
          number of Rights (other than Rights which have become void
          pursuant to the provisions of Section 11(a)(ii) hereof) held by
          each holder of Rights.

                (c)  In the event that there shall not be sufficient shares
          of Common Stock issued but not outstanding or authorized but
          unissued to permit any exchange of Rights as contemplated in 




                                         -35-


<PAGE>
          accordance with this Section 24, the Company may, in its
          discretion, take such action as may be necessary to authorize
          additional shares of Common Stock for issuance upon exchange of
          the Rights.  In the event that the Company shall determine not to
          take such action or shall, after good faith effort, be unable to
          take such action as may be necessary to authorize such additional
          shares of Common Stock, the Company shall substitute, to the
          extent of such insufficiency, for each share of Common Stock that
          would otherwise be issuable upon exchange of a Right, a number of
          shares of Preferred Stock or fractions thereof (or Equivalent
          Preferred Shares as such term is defined in Section 11(b)) having
          an aggregate Current Per Share Market Price (determined pursuant
          to Section 11(d) hereof) equal to the Current Per Share Market
          Price of one share of Common Stock (determined pursuant to
          Section 11(d) hereof) as of the date of issuance of such shares
          of Preferred Stock or fractions thereof (or Equivalent Preferred
          Shares).

                (d)  The Company shall not, in connection with any exchange
          pursuant to this Section 24, be required to issue fractions of
          shares of Common Stock or to distribute certificates which
          evidence fractional shares of Common Stock.  In lieu of such
          fractional shares of Common Stock, the Company shall pay to the
          registered holders of the Right Certificates with regard to which
          such fractional shares of Common Stock would otherwise be
          issuable an amount in cash equal to the same fraction of the
          current market value of a whole share of Common Stock.  For the
          purposes of this paragraph (d), the current market value of a
          whole share of Common Stock shall be the closing price of a share
          of Common Stock (as determined pursuant to the second sentence of
          Section 11(d)(i) hereof) for the Trading Day immediately prior to
          the date of exchange pursuant to this Section 24.

                Section 25.  Notice of Certain Events.  (a) In case the
                             ------------------------
          Company shall at any time after the earlier of the Distribution
          Date or the Stock Acquisition Date propose (i) to pay any
          dividend payable in stock of any class to the holders of its
          Preferred Stock or to make any other distribution to the holders
          of its Preferred Stock (other than a regular quarterly cash
          dividend), (ii) to offer to the holders of its Preferred Stock
          rights or warrants to subscribe for or to purchase any additional
          shares of Preferred Stock or shares of stock of any class or any
          other securities, rights or options, (iii) to effect any
          reclassification of its Preferred Stock (other than a
          reclassification involving only the subdivision of outstanding
          Preferred Stock), (iv) to effect the liquidation, dissolution or
          winding up of the Company, or (v) to declare or pay any dividend
          on the Common Stock payable in Common Stock or to effect a
          subdivision, combination or consolidation of the Common Stock (by
          reclassification or otherwise than by payment of dividends in
          Common Stock), then, in each such case, the Company shall give to
          each holder of a Right Certificate, in accordance with Section 26
          hereof, a notice of such proposed action, which shall specify the
          record date for the purposes of such stock dividend, or 




                                         -36-

          distribution of rights or warrants, or the date on which such
          liquidation, dissolution or winding up is to take place and the
          date of participation therein by the holders of the Common Stock
          and/or Preferred Stock, if any such date is to be fixed, and such
          notice shall be so given in the case of any action covered by
          clause (i) or (ii) above at least 10 days prior to the record
          date for determining holders of the Preferred Stock for purposes
          of such action, and in the case of any such other action, at
          least 10 days prior to the date of the taking of such proposed
          action or the date of participation therein by the holders of the
          Common Stock and/or Preferred Stock, whichever shall be the
          earlier.

                (b)  In case any event described in Section 11(a)(ii) or
          Section 13 shall occur, then the Company shall as soon as
          practicable thereafter give to each holder of a Right Certificate
          (or if occurring prior to the Distribution Date, the holders of
          the Common Stock) in accordance with Section 26 hereof, a notice
          of the occurrence of such event, which notice shall describe such
          event and the consequences of such event to holders of Rights
          under Section 11(a)(ii) and Section 13 hereof.

                             --------------------------
          provided in the penultimate sentence of this Section 27, for so
          long as the Rights are then redeemable, the Company may in its
          sole and absolute discretion, and the Rights Agent shall if the
          Company so directs, supplement or amend any provision of this
          Agreement in any respect without the approval of any holders of
          the Rights.  At any time when the Rights are no longer
          redeemable, except as provided in the penultimate sentence of
          this Section 27, the Company may, and the Rights Agent shall, if
          the Company so directs, supplement or amend this Agreement
          without the approval of any holders of Rights Certificates in
          order to (i) cure any ambiguity, (ii) correct or supplement any
          provision contained herein which may be defective or inconsistent
          with any other provisions herein, (iii) shorten or lengthen any
          time period hereunder, or (iv) change or supplement the
          provisions hereunder in any manner which the Company may deem
          necessary or desirable; provided that no such supplement or
                                  --------
          amendment shall adversely affect the interests of the holders of
          Rights as such (other than an Acquiring Person or an Affiliate or
          Associate of an Acquiring Person), and no such amendment may
          cause the Rights again to become redeemable or cause the
          Agreement again to become amendable other than in accordance with
          this sentence.  Notwithstanding anything contained in this 
          Agreement to the contrary, no supplement or amendment shall be
          made which changes the Redemption Price.  Upon the delivery of a
          certificate from an appropriate officer of the Company which
          states that the proposed supplement or amendment is in compliance
          with the terms of this Section 27, the Rights Agent shall execute
          such supplement or amendment.

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

                             --------------------------
          Agreement shall be construed to give to any Person other than the
          Company, the Rights Agent and the registered holders of the Right
          Certificates (and, prior to the Distribution Date, the Common
          Stock) any legal or equitable right, remedy or claim under this
          Agreement; but this Agreement shall be for the sole and exclusive
          benefit of the Company, the Rights Agent and the registered
          holders of the Right Certificates (and, prior to the Distribution
          Date, the Common Stock).

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

          administration of this Agreement (including, without limitation,
          a determination to redeem or not redeem the Rights or to amend
          this Agreement).  All such actions, calculations, interpretations
          and determinations (including, for purposes clause (y) below, all
          omissions with respect to the foregoing) that are done or made by
          the Board of Directors of the Company in good faith, shall (x) be
          final, conclusive and binding on the Company, the Rights Agent,
          the holders of the Rights, as such, and all other parties, and
          (y) not subject the Board of Directors to any liability to the
          holders of the Rights.

                             ------------
          covenant or restriction of this Agreement or applicable to this

          made under the laws of the State of New York and for all purposes
          shall be governed by and construed in accordance with the laws of
          such State applicable to contracts to be made and performed
          entirely within such State.

                Section 33.  Counterparts.  This Agreement may be executed
                             ------------
          in any number of counterparts and each of such counterparts shall

                              (Under Section 805 of the
                  Business Corporation Law of the State of New York)

                                 ___________________


                    We, the undersigned, JOHN K. PURCELL and JOSEPHINE S.
          TRUBEK, being respectively a Corporate Vice President and the
          Corporate Secretary of Frontier Corporation, do hereby CERTIFY
          that:

                    1.  The name of the Corporation is "Frontier
          Corporation".  The name under which the Corporation was
          incorporated is "ROCHESTER TELEPHONE CORPORATION".

                    2.  The Certificate of Incorporation of the Corporation
          was filed in the Department of State of the State of New York on
          February 25, 1920.  A Restated Certificate of Incorporation was
          filed in the Department of State of the State of New York on
          April 2, 1968.  A second Restated Certificate of Incorporation
          was filed in the Department of State of the State of New York on
          February 17, 1995 (such second Restated Certificate of
          Incorporation, the "Restated Certificate of Incorporation").

                    3.  The Restated Certificate of Incorporation is hereby
          amended to add a provision to Article FOURTH thereof stating the
          number, designation, relative rights, preferences and limitations
          of the Series A Junior Participating Class A Preferred Stock as
          fixed by the Board of Directors of the Corporation and to set
          forth in full the text of such provision.  To effect the
          foregoing, Article FOURTH of the Restated Certificate of
          Incorporation is amended to add the following at the end of such
          Article FOURTH:


          
                   



<PAGE>
                    I.   Series A Junior Participating Class A Preferred
                         Stock

                    There is hereby established a series of Class A
          Preferred Stock of the number and designation, and having
          relative rights, preference and limitations as follows:   

                    Section 1.  Designation and Amount.  The shares of such
                                ----------------------
               series shall be designated as "Series A Junior Participating
               Class A Preferred Stock" (the "Series A Preferred Stock")
               and the number of shares constituting the Series A Preferred
               Stock shall be 3,000,000.  Such number of shares may be in-
               creased or decreased by resolution of the Board of
               Directors; provided, that no decrease shall reduce the
                          --------
               number of shares of Series A Preferred Stock to a number
               less than the number of shares then outstanding plus the
               number of shares reserved for issuance upon the exercise of
               outstanding options, rights or warrants or upon the

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

                    (A)  Subject to the rights of the holders of any shares
               of any series of Preferred Stock of the Corporation (or any
               similar stock) ranking prior and superior to the Series A
               Preferred Stock with respect to dividends, the holders of
               shares of Series A Preferred Stock, in preference to the
               holders of Common Stock of the Corporation and of any other
               stock of the Corporation ranking junior to the Series A
               Preferred Stock, shall be entitled to receive, when, as and
               if declared by the Board of Directors out of funds legally
               available for the purpose, quarterly dividends payable in
               cash on the first day of January, April, July, and October
               in each year (each such date being referred to herein as a
               "Dividend Payment Date"), commencing on the first Dividend
               Payment Date after the first issuance of a share or fraction
               of a share of Series A Preferred Stock, in an amount per
               share (rounded to the nearest cent) equal to the greater of
               (a) $1 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, declared on the Common Stock since
               the immediately preceding Dividend Payment Date or, with
               respect to the first Dividend Payment Date, since the first
               issuance of any share or fraction of a share of Series A
               Preferred Stock.  In the event the Corporation shall at any
               time 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
               Series A Preferred Stock were entitled immediately prior to
               such event under clause (b) of the preceding sentence shall
               be adjusted by multiplying such amount by a fraction, the
               numerator of which is the number of shares of Common Stock
               outstanding immediately after such event and the denominator
               of which is the number of shares of Common Stock that were
               outstanding immediately prior to such event.

                    (B)  The Corporation shall declare a dividend or
               distribution on the Series A Preferred Stock as provided in
               paragraph (A) of this Section immediately after it declares
               a dividend or distribution on the Common Stock (other than a
               dividend payable in shares of Common Stock); provided that,
               in the event no dividend or distribution shall have been
               declared on the Common Stock during the period between any
               Dividend Payment Date and the next subsequent Dividend
               Payment Date, a dividend of $1 per share on the Series A
               Preferred Stock shall nevertheless be payable, when, as and
               if declared, on such subsequent Dividend Payment Date.

                    (C)  Dividends shall begin to accrue and be cumulative,
               whether or not earned or declared, on outstanding shares of
               Series A Preferred Stock from the 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 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 Dividend Payment
               Date or is a date after the record date for the
               determination of holders of shares of Series A Preferred
               Stock entitled to receive a quarterly dividend and before
               such Dividend Payment Date, in either of which events such
               dividends shall begin to accrue and be cumulative from such
               Dividend Payment Date.  Accrued but unpaid dividends shall
               not bear interest.  Dividends paid on the shares of Series A
               Preferred Stock in an amount less than the total amount of
               such dividends at the time accrued and payable on such
               shares shall be allocated pro rata on a share-by-share basis
               among all such shares at the time outstanding.  The Board of
               Directors may fix a record date for the determination of
               holders of shares of Series A Preferred Stock entitled to
               receive payment of a dividend or distribution declared
               thereon, which record date shall be not more than 50 days
               prior to the date fixed for the payment thereof.

                    Section 3.  Voting Rights.  The holders of shares of
                                -------------
               Series A Preferred Stock shall have the following voting
               rights;

                    (A)  Subject to the provision for adjustment
               hereinafter set forth and except as otherwise provided
               herein or in the Restated Certificate of Incorporation or

               required by law, each share of Series A Preferred Stock
               shall entitle the holder thereof to 100 votes on all matters
               upon which the holders of the Common Stock of the
               Corporation are entitled to vote.  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 Series A Preferred Stock were
               entitled immediately prior to such event shall be adjusted
               by multiplying such number by a fraction, the numerator of
               which is the number of shares of Common Stock outstanding
               immediately after such event and the denominator of which is
               the number of shares of Common Stock that were outstanding
               immediately prior to such event.

                    (B)  Except as otherwise provided herein or in the
               Restated Certificate of Incorporation or in any other
               Certificate of Amendment creating a series of Preferred
               Stock or any similar stock, and except as otherwise required
               by law, the holders of shares of Series A 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 stockholders of the Corporation.

                    (C)  Except as set forth herein, or as otherwise
               provided by law, holders of Series A Preferred Stock shall
               have no special voting rights and their consent shall not be
               required (except to the extent they are entitled to vote
               with holders of Common Stock as set forth herein) for taking
               any corporate action.

                    Section 4.  Certain Restrictions.
                                --------------------

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

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

                        (ii)  declare or pay dividends, or make any other
                    distributions, on any shares of stock ranking on a
                    parity (as to dividends) with the Series A Preferred
                    Stock, except dividends paid ratably on the Series A

                    Preferred Stock and all such parity stock on which
                    dividends are payable or in arrears in proportion to
                    the total amounts to which the holders of all such
                    shares are then entitled;

                    consideration shares of any stock ranking junior

                    dissolution or winding up) to the Series A 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 (as to dividends and
                    upon dissolution, liquidation or winding up) to the

                    to acquire such junior stock;

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

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

               Upon any liquidation, dissolution or winding up of the
               Corporation, no distribution shall be made (A) to the

               unless, prior thereto, the holders of shares of Series A
               Preferred Stock shall have received $100 per share, plus an
               amount equal to accrued and unpaid dividends and
               distributions thereon, whether or not earned or declared, to

               the date of such payment, provided that the holders of
               shares of Series A 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 (B) to the holders
               of shares of stock ranking on a parity upon liquidation,
               dissolution or winding up with the Series A Preferred Stock,
               except distributions made ratably on the Series A Preferred
               Stock and all such parity stock in proportion to the total
               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 Series A
               Preferred Stock were entitled immediately prior to such
               event under the proviso in clause (A) 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.

                                --------------------------
               Corporation shall enter into any consolidation, merger,
               combination or other transaction in which the shares of
               Common Stock are converted into, exchanged for or changed
               into other stock or securities, cash and/or any other
               property, then in any such case each share of Series A
               Preferred Stock shall at the same time be similarly
               converted into, exchanged for 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 converted, exchanged or converted. 
               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
               conversion, exchange or change of shares of Series A
               Preferred Stock shall be adjusted by multiplying such amount
               by a fraction, the numerator of which is the number of
               shares of Common Stock outstanding immediately after such
               event and the denominator of which is the number of shares

               the Restated Certificate of Incorporation (including this
               Certificate of Amendment) would alter, change or repeal any
               of the preferences, powers or special rights given to the
               Series A Preferred Stock so as to affect the Series A
               Preferred Stock adversely, then the holders of the Series A
               Preferred Stock shall be entitled to vote separately as a
               class upon such amendment, and the affirmative vote of
               two-thirds of the outstanding shares of the Series A
               Preferred Stock, voting separately as a class, shall be
               necessary for the adoption thereof, in addition to such
               other vote as may be required by the Business Corporation
               Law of the State of New York.

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

                    4.  This Certificate of Amendment of the Restated
          Certificate of Incorporation of the Corporation was authorized by

               BECOME NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE.

                            SUMMARY OF RIGHTS TO PURCHASE
                              Shares of Preferred Stock

                    On April 9, 1995, the Board of Directors of Frontier
          Corporation (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, of the Company (the
          "Common Stock").  The dividend is payable on April 24, 1995 (the
          "Record Date") to the shareowners of record on that date.  Each
          Right entitles the registered holder to purchase from the Company
          one one-hundredth of a share of Series A Junior Participating
          Class A Preferred Stock, par value $100 per share (the "Preferred
          Stock"), of the Company at a price of $80 per one one-hundredth
          of a share of Preferred Stock (the "Purchase Price"), subject to
          adjustment.  The description and terms of the Rights are set
          forth in a Rights Agreement dated as of April 9, 1995, as the
          same by be amended from time to time (the "Rights Agreement"),
          between the Company and The First National Bank of Boston, as
          Rights Agent (the "Rights Agent").

                    Until the earlier to occur of (i) 10 days following the
          first date of a public announcement that a person or group of
          affiliated or associated persons (an "Acquiring Person") have
          acquired beneficial ownership of 20% or more of the outstanding
          shares of Common Stock or such earlier date as a majority of the
          Board of Directors shall have become aware of the existence of an
          Acquiring Person, or (ii) 10 business days (or such later date as
          may be determined by action of the Board of Directors prior to
          such time as any person or group of affiliated persons becomes an
          Acquiring Person) 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 20% or more of the outstanding shares of
          Common Stock (the earlier of such dates being called the
          "Distribution Date"), the Rights will be evidenced, with respect
          to any of the Common Stock certificates outstanding as of the
          Record Date, by such Common Stock certificate together with a
          copy of this Summary of Rights.

                    The Rights Agreement provides that, until the
          Distribution Date (or earlier redemption or expiration of the
          Rights), the Rights will be transferred with and only with the
          Common Stock.  Until the Distribution Date (or earlier redemption
          or expiration of the Rights), new Common Stock certificates
          issued after the Record Date (including, without limitation, upon
          transfer or new issuances of Common Stock) will contain a 





<PAGE>
          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
          shares of Common Stock outstanding as of the Record Date, even
          without such notation or a copy of this Summary of Rights, will
          also constitute (except as otherwise provided in the Rights
          Agreement) the transfer of the Rights associated with the shares
          of Common Stock 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 Stock 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 April 24, 2005 (the "Final
          Expiration Date"), unless the Final Expiration Date is extended
          or unless the Rights are earlier redeemed or exchanged by the
          Company, in each case as described below.

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

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

                    Shares of Preferred Stock purchasable upon exercise of
          the Rights will not be redeemable.  Each share of Preferred Stock
          will be entitled, when, as and if declared, to a minimum
          preferential quarterly dividend payment of $1 per share but will
          be entitled to an aggregate dividend of 100 times the dividend
          declared per share of Common Stock.  In the event of liquidation,
          the holders of the Preferred Stock will be entitled to a minimum
          preferential liquidation payment of $100 per share (plus any
          accrued but unpaid dividends) but will be entitled to an
          aggregate payment of 100 times the payment made per share of
          Common Stock.  Each share of Preferred Stock will have 100 votes,

          voting together with the Common Stock.  Finally, in the event of
          any merger, consolidation or other transaction in which shares of
          Common Stock are converted or exchanged, each share of Preferred
          Stock will be entitled to receive 100 times the amount received
          per share of Common Stock.  These rights are protected by
          customary antidilution provisions.

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

                    In the event that any person or group of affiliated or
          associated persons becomes an Acquiring Person, each holder of a
          Right, other than Rights beneficially owned by the Acquiring
          Person (which will thereupon become void), will thereafter have
          the right to receive upon exercise of a Right at the then current
          exercise price of the Right, that number of shares of Common
          Stock having a market value of two times the exercise price of
          the Right.

                    In the event that, after a person or group has become
          an Acquiring Person, the Company is acquired in a merger or other
          business combination transaction or 50% or more of its
          consolidated assets or earning power are sold, proper provision
          will be made so that each holder of a Right (other than Rights
          beneficially owned by an Acquiring Person which will have become
          void) 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 person with whom the
          Company has engaged in the foregoing transaction (or its parent),
          which number of shares at the time of such transaction will have
          a market value of two times the exercise price of the Right.  

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

                    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
          shares of Preferred Stock will be issued (other than fractions
          which are integral multiples of one one-hundredth of a share of
          Preferred Stock, 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 




                                         C-3


<PAGE>
          Preferred Stock on the last trading day prior to the date of
          exercise.

                    At any time prior to the time an Acquiring Person
          becomes such, the Board of Directors of the Company may redeem
          the Rights in whole, but not in part, at a price of $.01 per
          Right (the "Redemption Price"), subject to adjustment.  The
          redemption of the Rights may be made effective at such time, on
          such basis and with such conditions as the Board of Directors in
          its sole discretion may establish.  Immediately upon any
          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.

                    For so long as the Rights are then redeemable, the
          Company may, except with respect to the redemption price, amend
          the Rights in any manner.  After the Rights are no longer
          redeemable, the Company may, except with respect to the
          redemption price, amend the Rights in any manner that does not
          adversely affect the interests of holders of the Rights. 

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

                    A copy of the Rights Agreement has been filed with the
          Securities and Exchange Commission as an Exhibit to a
          Registration Statement on Form 8-A dated April 13, 1995.  A copy
          of the Rights Agreement is available free of charge from the
          Company.  This summary description of the Rights does not purport
          to be complete and is qualified in its entirety by reference to
          the Rights Agreement, as the same may be amended from time to
          time, which is hereby incorporated herein by reference.
