                    WARRANT AGREEMENT, dated as of May 1, 1995, among PAINE
          WEBBER GROUP INC., a corporation organized and existing under the
          laws of the State of Delaware (the "Company"), CITIBANK, N.A., a
          national banking association organized and existing under the
          laws of the United States of America (the "Warrant Agent"), and
          PAINEWEBBER INCORPORATED, a corporation organized and existing
          under the laws of the State of Delaware (the "Spot Rate Reference
          Agent").

                    WHEREAS the Company proposes to sell warrants (the
          "Warrants" or, individually, a "Warrant") representing the right
          to receive from the Company the amount, if any, in U.S. dollars
          determined by reference to decreases in the value of the Japanese
          yen relative to the U.S. dollar on the terms and conditions set
          forth in this Agreement; and

                    WHEREAS the Company desires the Warrant Agent to act on
          behalf of the Company, and the Warrant Agent is willing so to
          act, in connection with the issuance, transfer and exercise of
          the Warrants, and the Company desires to set forth herein, among
          other things, the provisions of the Warrants and the terms and
          conditions on which they may be issued, transferred, exercised
          and canceled;


                    NOW, THEREFORE, the parties hereto agree as follows:


                                      ARTICLE I

                            ISSUANCE OF WARRANTS AND FORM,
                         EXECUTION, DELIVERY AND REGISTRATION
                             OF WARRANT CERTIFICATES AND
                              GLOBAL WARRANT CERTIFICATE

                    SECTION 1.01.  Issuance of Warrants.  (a)  The Warrants
          will constitute direct, unconditional and unsecured
          obligations of the Company and will rank on a parity with the
          Company's other unsecured contractual obligations and with the
          Company's unsecured and unsubordinated debt.

                    (b)  Each Warrant shall represent the right, subject to
          the provisions contained herein, to receive the Cash Settlement
          Value (as defined herein) of such Warrant.  In no event shall a
          registered or beneficial holder of a Warrant (each a
          "Warrantholder") be entitled to receive any interest on any Cash
          Settlement Value.

                    (c)  Forty-five calendar days after the date of this
          Agreement each Warrantholder will have a one-time option to
          convert the form in which such Warrantholder holds his Warrants
          from certificated to book-entry form (the "Conversion Option"). 


          The Conversion Option will be available for forty-five calendar
          days from June 15, 1995, through July 29, 1995 (the "Conversion

<PAGE>



          Option Period").  To utilize the Conversion Option a
          Warrantholder must deliver or arrange to deliver his Warrants to
          an entity (a "Participant") entitled to execute, clear and settle
          transactions through the Depository (as defined herein) through
          which such Warrantholder's beneficial interest after electing the
          Conversion Option will be maintained, who will then deposit the
          Warrants with the Depository or its nominee.  Once a
          Warrantholder has elected the Conversion Option such
          Warrantholder may hold his Warrants only in book-entry form and
          will not be able to change his election or withdraw from the
          book-entry system during the Conversion Option Period or
          thereafter.  Accordingly, except as hereinafter provided,
          ownership of the Warrants in certificated form will no longer be
          available to Warrantholders who have elected the Conversion
          Option and ownership of the Warrants surrendered under the
          Conversion Option will be represented by a single certificate
          (the "Global Warrant Certificate"); provided, however, that if
          the Depository is at any time unwilling or unable to continue as
          securities depository for the Warrants and a successor Depository
          is not appointed by the Company within 90 days, the Company will
          reissue Warrant Certificates (as defined herein) in exchange for
          the Global Warrant Certificate. In addition, the Company may at
          any time determine not to have the Warrants represented by a
          Global Warrant Certificate and, in such event, will issue Warrant
          Certificates in exchange for the Global Warrant Certificate.  In
          either instance, and in accordance with the provisions of this
          Agreement, each Warrantholder will be entitled to have a number
          of Warrants equal to such Warrantholder's beneficial interest in
          the Global Warrant Certificate registered in the name of the
          Warrantholder and will be entitled to physical delivery of such
          Warrants in certificated form by a Participant.  The provisions
          of Section 1.07 shall apply only if and when the Conversion
          Option is utilized and a Global Warrant Certificate is issued
          hereunder.  Unless the context shall otherwise require, and
          subject to the provisions of Section 1.07, all references in this
          Agreement to the Warrant Certificates (other than in Sections
          1.02, 1.03, 1.04, 1.05, 1.06 and 1.07) shall include the Global
          Warrant Certificate in the event that the Global Warrant
          Certificate is issued.

                    (d)  Warrantholders shall not be entitled to hold
          Warrants in certificated form through CEDEL or Euroclear (as such
          terms are defined herein).

                    SECTION 1.02.  Form, Execution and Delivery of Warrant
          Certificates.  (a)  The Warrants, whenever issued, shall be
          represented by certificates in registered form substantially in


          the form set forth in Exhibit A hereto (the "Warrant
          Certificates"), with such appropriate insertions, omissions,
          substitutions and other variations as are required or permitted
          by this Agreement, and may represent any number of whole
          Warrants.  The Warrant Certificates may have imprinted or
          otherwise reproduced thereon such letters, numbers or other marks
          of identification or designation and such legends or endorsements

          
                                          2

          as the officers of the Company executing the same may approve
          (execution thereof to be conclusive evidence of such approval)
          and which are not inconsistent with the provisions of this
          Agreement, or as may be required to comply with any law or with
          any rule or regulation made pursuant thereto, or with any rule or
          regulation of any stock exchange on which the Warrants may be
          listed, or of the Depository, or to conform to usage.  Warrant
          Certificates shall be signed on behalf of the Company by its
          chairman, its president or one of its vice presidents and under
          its corporate seal reproduced thereon and attested by its
          secretary or an assistant secretary.  The signature of any of
          such officers may be either manual or facsimile.  Typographical
          and other minor errors or defects in any such signature shall not
          affect the validity or enforceability of any Warrant Certificate
          that has been duly countersigned and delivered by the Warrant
          Agent.

                    (b)  In case any officer of the Company who shall have
          signed a Warrant Certificate, either manually or by facsimile
          signature, shall cease to be such officer before such Warrant
          Certificate shall have been countersigned and delivered by the
          Warrant Agent to the Company or delivered by the Company, such
          Warrant Certificate nevertheless may be countersigned and
          delivered as though the person who signed such Warrant Certifi-
          cate had not ceased to be such officer of the Company; and the
          Warrant Certificate may be signed on behalf of the Company by any
          person who, at the actual date of the execution of such Warrant
          Certificate, shall be a proper officer of the Company to sign
          such Warrant Certificate, although at the date of the execution
          of this Warrant Agreement any such person was not such officer.

                    SECTION 1.03.  Warrant Certificates.  Each Warrant
          Certificate, when signed on behalf of the Company in accordance
          with Section 1.02, shall be delivered to the Warrant Agent, which
          shall manually countersign and deliver the same to or upon the
          order of the Company.  Each Warrant Certificate shall be dated
          the date of its countersignature.  A Warrant Certificate shall
          not be valid for any purpose, and no Warrant evidenced thereby
          shall be exercisable, unless and until such Warrant Certificate


          has been countersigned by the manual signature of the Warrant
          Agent.  Such countersignature by the Warrant Agent upon any
          Warrant Certificate signed by the Company in accordance with
          Section 1.02 shall be conclusive evidence that the Warrant
          Certificate so countersigned has been duly issued hereunder.

                    SECTION 1.04.  Registration of Transfers and Exchanges. 
          (a)  Except as otherwise provided herein or in the Warrant
          Certificate, the Warrant Agent shall from time to time register
          the transfer of any outstanding Warrant Certificates upon the
          records to be maintained by it for that purpose (the "Warrant
          Register") at the Warrant Agent's Office (as defined herein),
          subject to such reasonable regulations as the Company or the
          Warrant Agent may prescribe, upon surrender thereof, duly
          endorsed, or accompanied by a written instrument or instruments

          
                                          3

          of transfer in form satisfactory to the Warrant Agent and the
          Company, duly executed by, the registered holder(s) thereof or by
          the duly appointed legal representative thereof or by a duly
          authorized attorney, such signature to be guaranteed by a bank or
          trust company with a correspondent office in The City of New York
          or by a member of a national securities exchange.  Upon any such
          registration of transfer, a new Warrant Certificate shall be
          issued to the transferee(s) and the surrendered Warrant
          Certificate shall be canceled by the Warrant Agent.

                    (b)  At the option of a Warrantholder, Warrant
          Certificates may be exchanged for other Warrant Certificates, of
          like tenor and representing an equal number of unexercised
          Warrants, upon surrender to the Warrant Agent of the Warrant
          Certificates to be exchanged at its offices maintained for such
          purpose (the location of which shall be provided to the Company),
          which shall be south of Chambers Street in the Borough of Manhat-
          tan, The City of New York (the "Warrant Agent's Office"), and
          which are, on the date of this Agreement, 111 Wall Street, New
          York, New York 10043, Attention:  Corporate Trust Department, or
          at the office of any successor Warrant Agent (as provided in
          Section 5.03).  Upon surrender of any Warrant Certificate for
          exchange, the Warrant Agent shall cancel such Warrant
          Certificate, and the Company shall execute, and the Warrant Agent
          shall countersign and deliver, in accordance with Sections 1.02
          and 1.03, one or more new Warrant Certificates of like tenor and
          representing an equal number of unexercised Warrants.  

                    (c)  Warrant Certificates issued upon transfer or
          exchange pursuant to Section 1.04(a) or (b) shall be valid


          obligations of the Company, evidencing the same obligations of
          the Company as the Warrant Certificates surrendered for transfer
          or exchange, and entitled to the same benefits under this
          Agreement as were such Warrant Certificates prior to such
          surrender.

                    (d)  Except as provided in Section 1.05, no service
          charge shall be made for any registration of transfer or exchange
          of Warrant Certificates, but the Company may require payment of a
          sum sufficient to cover any tax or other governmental charge that
          may be imposed in connection with any registration of transfer or
          exchange of Warrant Certificates, other than exchanges pursuant
          to this Section 1.04 not involving any transfer.

                    (e)  In the event that upon any exercise of Warrants
          evidenced by a Warrant Certificate the number of Warrants
          exercised shall be less than the total number of Warrants
          evidenced by such Warrant Certificate, there shall be issued to
          the holder thereof or his assignee a new Warrant Certificate
          evidencing the number of Warrants not exercised.

                    SECTION 1.05.  Mutilated or Missing Warrant
          Certificates.  (a)  If any Warrant Certificate is mutilated,
          lost, stolen or destroyed, the Company may in its discretion

          
                                          4

          execute, and the Warrant Agent may countersign and deliver, in
          exchange and substitution for and upon cancellation of the
          mutilated Warrant Certificate, or in lieu of the Warrant
          Certificate lost, stolen or destroyed, a new Warrant Certificate
          of like tenor and representing an equal number of unexercised
          Warrants, bearing an identification number not contemporaneously
          outstanding, but only (in case of loss, theft or destruction)
          upon receipt of evidence satisfactory to the Company and the
          Warrant Agent of such loss, theft or destruction of such Warrant
          Certificate and security or indemnity, if requested, also
          satisfactory to them.  Applicants for such substitute Warrant
          Certificates shall also comply with such other reasonable
          regulations and pay such other reasonable charges as the Company
          or the Warrant Agent may prescribe.

                    (b)  In case any such mutilated, lost, stolen or
          destroyed Warrant Certificate has been or is about to be
          exercised, or deemed to be exercised, the Company in its absolute
          discretion may, instead of issuing a new Warrant Certificate,
          direct the Warrant Agent to treat the same as if it had received
          a Notice of Exercise (as defined herein) in proper form in


          respect thereof, as provided herein, or as being subject to
          automatic exercise, as the case may be.

                    (c)  Each new Warrant Certificate issued pursuant to
          this Section 1.05 in lieu of any mutilated, lost, stolen or
          destroyed Warrant Certificate shall be an original, additional
          contractual obligation of the Company, whether or not, in the
          case of any lost, stolen or destroyed Warrant Certificate, such
          Warrant Certificate shall at any time be enforceable by anyone,
          and shall be entitled to the same benefits under this Agreement
          as the Warrant Certificate that was mutilated, lost, stolen or
          destroyed.

                    (d)  Upon the issuance of any new Warrant Certificate
          in accordance with this Section 1.05, the Company may require the
          payment of a sum sufficient to cover any tax or other
          governmental charge that may be imposed in relation thereto and
          any other expenses (including the fees and expenses of the
          Warrant Agent) connected therewith.

                    (e)  The provisions of this Section 1.05 are exclusive
          and shall preclude (to the extent lawful) any other rights and
          remedies with respect to the replacement or payment of mutilated,
          lost, stolen or destroyed Warrant Certificates.

                    SECTION 1.06.  Registered Holders.  Prior to due
          presentment for registration of transfer, the Company, the
          Warrant Agent, and any agent of the Company or the Warrant Agent,
          may deem and treat the person in whose name a Warrant Certificate
          shall be registered in the Warrant Register (a "Registered
          Holder") as the absolute owner of the Warrants evidenced thereby
          (notwithstanding any notation of ownership or other writing
          thereon) for any purpose whatsoever, and as the person entitled

          
                                          5  
 
<PAGE>




          to exercise the rights represented by the Warrants evidenced
          thereby, and neither the Company nor the Warrant Agent, nor any
          agent of the Company or the Warrant Agent, shall be affected by
          any notice to the contrary.  This Section 1.06 shall be without
          prejudice to the rights of Warrantholders as described elsewhere
          herein.

                    SECTION 1.07.  Global Warrant Certificate.  (a)  Any
          Global Warrant Certificate issued in accordance with Section 1.01
          shall be substantially in the form set forth in Exhibit B-1
          hereto, with such appropriate insertions, omissions,
          substitutions and other variations as are required or permitted


          by this Agreement, and may represent any number of whole
          Warrants.  The Global Warrant Certificate may have imprinted or
          otherwise reproduced thereon such letters, numbers or other marks
          of identification or designation and such legends or endorsements
          as the officers of the Company executing the same may approve
          (execution thereof to be conclusive evidence of such approval)
          and which are not inconsistent with the provisions of this
          Agreement, or as may be required to comply with any law or with
          any rule or regulation made pursuant thereto, or with any rule or
          regulation of any stock exchange on which the Warrants may be
          listed, or of the Depository, or to conform to usage.  The Global
          Warrant Certificate shall be signed on behalf of the Company upon
          the same conditions, in substantially the same manner and with
          the same effect as the Warrant Certificates.

                    (b)  The Warrant Agent is authorized, from time to time
          during the Conversion Option Period, upon receipt of a Global
          Warrant Certificate from the Company, duly executed on behalf of
          the Company, to countersign such Global Warrant Certificate.  The
          Global Warrant Certificate shall be manually countersigned and
          dated the date of its countersignature by the Warrant Agent and
          shall not be valid for any purpose unless so countersigned.  The
          Warrant Agent shall deliver the Global Warrant Certificate to or
          upon the order of the Company against receipt of an appropriate
          amount of Certificated Warrants (such Certificated Warrants shall
          be destroyed or otherwise disposed of in accordance with
          instructions provided by the Company).  One or more Global
          Warrant Certificates may be executed by the Company and delivered
          to the Warrant Agent on or after the date of execution of this
          Agreement; provided that only one Global Warrant Certificate
          shall be outstanding at any one time.

                    The Company reserves the right to issue, from time to
          time after the date of execution of this Agreement, additional
          Warrants, and in connection therewith the Global Warrant
          Certificate may be exchanged for a new Global Warrant Certificate
          to reflect the issuance by the Company of such additional
          Warrants.  To effect such an exchange the Company shall deliver
          to the Warrant Agent a new Global Warrant Certificate duly
          executed on behalf of the Company as provided in Section 1.02. 
          The Warrant Agent shall authenticate the new Global Warrant
          Certificate as provided in this Section and shall deliver the new

          
                                          6  
 
<PAGE>




          Global Warrant Certificate to the Depository in exchange for, and
          upon receipt of, the Global Warrant Certificate then held by the
          Depository.  The Warrant Agent shall cancel the Global Warrant


          Certificate delivered to it by the Depository, destroy such
          Global Warrant Certificate and provide a certificate of
          destruction to the Company.

                    (c)  The Global Warrant Certificate will initially be
          registered in the name of a nominee of The Depository Trust
          Company (the "Depository", which term, as used herein, includes
          any successor securities depository selected by the Company). 
          The Warrant holdings of the Participants will be recorded on the
          books of the Depository.  The holdings of customers of the
          Participants and the identity of the Warrantholders will be
          reflected on the books and records of such Participants and will
          not be known to the Warrant Agent, the Company or the Depository. 
          The Global Warrant Certificate will be held by the Depository or
          its agent.

                    The Company may from time to time select a new entity
          to act as Depository with respect to the Warrants and, if such
          selection is made, the Company shall promptly give the Warrant
          Agent notice to such effect identifying the new Depository, and
          the Global Warrant Certificate shall be delivered to the Warrant
          Agent and shall be transferred to the new Depository as provided
          below as promptly as possible.  Appropriate changes may be made
          in the forms of the Global Warrant Certificate, the Notice of
          Exercise and the related notices to be delivered in connection
          with an exercise to reflect the selection of the new Depository.

                    (d)  Except as otherwise provided herein or in the
          Global Warrant Certificate, the Warrant Agent shall from time to
          time register the transfer of the Global Warrant Certificate in
          its records (which may be maintained electronically), subject to
          such reasonable regulations as the Company or the Warrant Agent
          may prescribe, only to the Depository, to another nominee of the
          Depository, to a successor Depository or to a nominee of a
          successor Depository, upon surrender of such Global Warrant
          Certificate, duly endorsed, or accompanied by a written
          instrument or instruments of transfer in form satisfactory to the
          Warrant Agent and the Company, duly executed by the Registered
          Holder thereof or by the duly appointed legal representative
          thereof, or by its duly authorized attorney, such signature to be
          guaranteed by a bank or trust company with a correspondent office
          in The City of New York or by a member of a national securities
          exchange.  Upon any such registration of transfer, a new Global
          Warrant Certificate shall be issued to the transferee and the
          surrendered Global Warrant Certificate shall be canceled by the
          Warrant Agent.

                    The Global Warrant Certificate may be transferred as
          provided above at the option of the holder thereof, when
          surrendered to the Warrant Agent's Office, or at the office of
          any successor Warrant Agent (as provided in Section 5.03), for

          another Global Warrant Certificate of like tenor and representing
          an equal number of unexercised Warrants.

                          DURATION AND EXERCISE OF WARRANTS

                    SECTION 2.01.  Duration of Warrants; Minimum Exercise
          Amounts; Notice of Exercise.  Subject to the limitations set
          forth herein and in Section 2.03, each Warrant may be irrevocably
          exercised in whole but not in part, at or prior to 3:00 p.m., New
          York City time, on any New York Business Day from its date of
          issuance until 3:00 p.m., New York City time, on the earlier of
          (i) the New York Business Day immediately preceding April 30,
          1996 (the "Expiration Date") and (ii) the Delisting Date (as
          defined herein).  Except in the event of automatic exercise, each
          Warrant shall be irrevocably exercised either (i) in the case of
          Warrants represented by Warrant Certificates ("Certificated
          Warrants"), by surrender to the Warrant Agent (at its address as
          set forth in such form of notice or at such other address as the
          Warrant Agent may specify from time to time) of the Warrant
          Certificate representing such Warrant, with the Notice of
          Exercise duly completed and executed by the Registered Holder of
          such Warrant or (ii) in the case of Warrants represented by the
          Global Warrant Certificate ("Book-Entry Warrants"), upon receipt
          by the Warrant Agent of such Warrant delivered free on the
          records of the Depository to the Warrant Agent's Depository
          Participant Account (entitled Citibank, N.A. Corporate Trust
          Warrant Agent Account, No. 2659, or such other account at the
          Depository as the Warrant Agent shall designate in writing to the
          Company) (the "Warrant Account") pursuant to a Notice of Exercise
          to the Warrant Agent from a Participant, in the case of Book-
          Entry Warrants held through the Depository, CEDEL, in the case of
          such Warrants held through CEDEL, or a Euroclear participant, in
          the case of such Warrants held through Euroclear, acting,
          directly or indirectly, on behalf of the Warrantholder; provided,
          however, that Notices of Exercise are subject to rejection by the
          Warrant Agent as provided herein.  Not fewer than 500 Warrants in
          either certificated or book-entry form may be exercised by or on
          behalf of any one Warrantholder at any one time, except in the
          event of automatic exercise on the Expiration Date or the
          Delisting Date or as provided in Section 2.04.  A Notice of
          Exercise shall be unconditional.  Except as provided in Sec-
          tion 2.02(b), the Warrant Agent shall be entitled, with no duty
          of inquiry, to rely conclusively on any Notice of Exercise
          received by it.  "Notice of Exercise" means an irrevocable notice
          of exercise to the Warrant Agent at its address, which notice


          (A) for Certificated Warrants, shall be on the reverse of the
          Warrant Certificate or on such other form as the Company and the
          Warrant Agent may approve, and (B) for Book-Entry Warrants, shall
          be substantially in the form set forth in Exhibit B-2 hereto or
          such other form as the Company and the Warrant Agent may approve
          and may be given by facsimile transmission.  For purposes of this

          Agreement, "New York Business Day" means any day other than a
          Saturday, Sunday or a day on which the New York Stock Exchange
          (the "NYSE") is not open for securities trading or commercial
          banks in New York City are required or authorized by law or
          executive order to remain closed.

                    SECTION 2.02.  Exercise and Delivery of Warrants. 
          (a)  Except in the event of automatic exercise on the Expiration
          Date or the Delisting Date, or in the event of a postponement
          pursuant to Section 2.04, the valuation date (the "Valuation
          Date") for a Warrant shall be the first New York Business Day
          next succeeding the New York Business Day (the "Exercise Date")
          on which the Warrant Agent has received (i) in the case of
          Warrants other than those held through the facilities of Centrale
          de Livraison de Valeurs Mobilieres S.A. ("CEDEL") or the
          Euroclear System ("Euroclear"), either (A) for Certificated
          Warrants, the Warrant Certificate representing such Warrant with
          the Notice of Exercise duly completed and executed or (B) for
          Book-Entry Warrants, the Warrant with the Notice of Exercise duly
          completed and executed, in either case, at or prior to 3:00 p.m.,
          New York City time (the "Notice Date"); and if the Warrant Agent
          shall receive any such Warrant Certificate or Warrant or Notice
          of Exercise after 3:00 p.m., New York City time, on such New York
          Business Day, then such Warrant Certificate or Warrant shall be
          deemed to have been received at or prior to 3:00 p.m., New York
          City time, on the New York Business Day next succeeding such New
          York Business Day (which shall be considered the Notice Date),
          and in such event the Valuation Date shall be the next New York
          Business Day following the New York Business Day on which the
          Warrant Agent is deemed to have received such Warrant Certificate
          or Warrant together with the Notice of Exercise or (ii) in the
          case of Warrants held through the facilities of CEDEL or
          Euroclear, the Notice of Exercise (by facsimile transmission) at
          or prior to 3:00 p.m., New York City time, provided that the
          Warrant is received by the Warrant Agent by 3:00 p.m., New York
          City time, on the applicable Valuation Date; and if the Warrant
          Agent shall receive such Notice of Exercise after 3:00 p.m., on
          any New York Business Day, then the Notice of Exercise shall be
          deemed to have been received at or prior to 3:00 p.m., New York


          City time, on the next succeeding New York Business Day (which
          shall be considered the Notice Date), and in such event the
          Valuation Date shall be the next New York Business Day following
          the New York Business Day on which the Warrant Agent is deemed to
          have received such Notice of Exercise; provided, however, that if
          the Warrant Agent receives the Warrant after 3:00 p.m., New York
          City time, on the Valuation Date, then the Exercise Date for such
          Warrant shall be the day on which such Warrant is received or, if
          such day is not a New York Business Day, the next succeeding
          New York Business Day, and the Valuation Date for such Warrant
          shall be the first New York Business Day following such Exercise
          Date; provided further, however, that in the case of exercises by
          Euroclear participants, Euroclear must, by tested telex to the
          Warrant Agent by 9:00 a.m., New York City time, on the Valuation
          Date, confirm (a "Euroclear Confirmation") that the Warrants will

          
                                          9  
<PAGE> 





          be received by the Warrant Agent by 3:00 p.m., New York City
          time, on such Date.  If such Euroclear Confirmation is received
          after 9:00 a.m., New York City time, on the Valuation Date, the
          Company will be entitled to direct the Warrant Agent to reject
          the related Notice of Exercise or waive the requirement for
          timely delivery of such Euroclear Confirmation.  Any Warrant
          Certificate or Warrant received after 3:00 p.m., New York City
          time, on the earlier of (1) the New York Business Day immediately
          preceding the Expiration Date and (2) the last New York Business
          Day prior to the effective date on which the Warrants are
          delisted from, or permanently suspended from trading on (within
          the meaning of the Securities Exchange Act of 1934 and the rules
          and regulations of the Securities and Exchange Commission
          thereunder), the NYSE and not accepted at the same time for
          listing on another United States national securities exchange
          (such New York Business Day being the "Delisting Date") (or, in
          the case of Warrants held through the facilities of CEDEL or
          Euroclear, after 3:00 p.m., New York City time, on the first
          New York Business Day following such dates), shall be deemed not
          to have been delivered and the related Notice of Exercise shall
          be void and of no effect; provided, however, that if the Company
          first receives notice of such delisting or suspension of the
          Warrants on the same day on which such Warrants are delisted or
          suspended, such day will be deemed the Delisting Date for
          purposes of this Agreement.  

                    (b)  The Warrant Agent shall, in the case of Warrants
          other than those held through CEDEL or Euroclear, following
          receipt of proper delivery of a Warrant in accordance with
          Section 2.02(a), accompanied by a completed Notice of Exercise,


          and, in the case of Warrants held through CEDEL or Euroclear,
          following receipt of proper delivery of a completed Notice of
          Exercise in accordance with Section 2.02(a):

                    (i) promptly (1) for Certificated Warrants, determine
               whether such Notice of Exercise has been duly completed and
               is in proper form duly executed by the Registered Holder
               thereof or by the duly appointed legal representative
               thereof or by a duly authorized attorney, (2) for Book-Entry
               Warrants not held through CEDEL or Euroclear, determine
               whether such Notice of Exercise has been duly completed and
               is in proper form and (3) for Book-Entry Warrants held
               through CEDEL or Euroclear, determine whether such Notice of
               Exercise has been duly completed and is in proper form duly
               executed by CEDEL or the Euroclear participant tendering
               such Warrant, as applicable; and if the Warrant Agent deter-
               mines that the Notice of Exercise has not been duly
               completed or is not in proper form or, in the case of
               Certificated Warrants, has not been so executed, the Warrant
               Agent promptly shall (X) reject such Notice of Exercise and
               shall send to the entity that executed such Notice of
               Exercise a notice of rejection substantially in the form set
               forth in Exhibit C-1 or Exhibit C-2 hereto, as appropriate,
               and, in the case of Certificated Warrants, return to the

               Registered Holder that submitted such Notice of Exercise, by
               first class mail, the Warrant Certificates evidencing such
               Warrants, or, in the case of Book-Entry Warrants, shall
               redeliver such Warrants (to the extent received in the case
               of Warrants held through CEDEL or Euroclear) free through
               the facilities of the Depository to the account from which
               they were transferred to the Warrant Agent and (Y) in either
               case, shall not take the actions required by clauses (ii)-
               (ix) below with respect to such Notice of Exercise or the
               related Warrants; provided, however, that the Warrant Agent
               shall deliver a copy of the Notice of Exercise relating to
               such Warrants to the Company as required by Section
               2.02(b)(ix) below and the Company may waive any defect in
               the form of such Notice of Exercise;

                    (ii)  with respect to each Warrant held through
               Euroclear for which a Notice of Exercise was received,
               promptly telephone Euroclear to determine whether Euroclear
               anticipates that it will be able to provide a Euroclear
               Confirmation as required by Section 2.02(a);



                    (iii) notify the Company and the Spot Rate Reference
               Agent (and such other parties (not to exceed two) as the
               Company shall designate in writing) by 5:00 p.m., New York
               City time, on the New York Business Day that such Notice of
               Exercise has been received (or shall be deemed to have been
               received) of (A) the total number of Warrants covered by
               such Notice of Exercise, (B) the number of such Warrants
               subject to the Limit Option (as defined herein)
               ("Contingently Tendered Warrants"), (C) the number of such
               Warrants not subject to the Limit Option and (D) the number
               of such Warrants, if any, as to which Euroclear has not
               advised the Warrant Agent that it anticipates being able to
               provide a Euroclear Confirmation as required by Section
               2.02(a);

                    (iv) with respect to Warrants held through Euroclear,
               determine whether the Warrant Agent has received by
               9:00 a.m., New York City time, on the Valuation Date
               relating to such Warrants, Euroclear Confirmations with
               respect to such Warrants as required by Section 2.02(a), and
               if the Warrant Agent has not received any such Euroclear
               Confirmation by such time, notify the Company (and such
               other parties (not to exceed two) as the Company shall
               designate in writing) by 10:00 a.m., New York City time, on
               such Valuation Date of the number of such Warrants in
               respect of which the Warrant Agent has not received such
               Euroclear Confirmations and (except to the extent the
               Company has notified the Warrant Agent that it has waived
               the requirement of timely delivery of such Euroclear
               Confirmation) send to the Euroclear participant that
               executed such Notice of Exercise for which no related
               Euroclear Confirmation was received (at the address

               specified in such notice) a notice of rejection
               substantially in the form set forth in Exhibit C-2 hereto;

                    (v) if any of the Warrants covered by such Notice of
               Exercise constitute Contingently Tendered Warrants, the
               Warrant Agent shall, by 5:00 p.m., New York City time, on
               the first New York Business Day following the New York
               Business Day that such Notice of Exercise has been received
               (or shall be deemed to have been received), (A) obtain from
               the Spot Rate Reference Agent the Reference Rate (as defined
               herein) for such Warrants and the Spot Rate (as defined
               herein) for the New York Business Day that, but for the


               provisions of Section 2.02(g), would be the Valuation Date
               for such Warrants, (B) determine in accordance with
               Section 2.02(g) whether such Contingently Tendered Warrants
               will be subject to exercise after giving effect to the Limit
               Option and, if such Warrants will not be subject to
               exercise, send to the Registered Holder, in the case of
               Certificated Warrants, or to the Participant, in the case of
               the Book-Entry Warrants, that submitted such Notice of
               Exercise a notice of rejection substantially in the form set
               forth in Exhibit D-1 or Exhibit D-2 hereto, as appropriate,
               with respect to such Warrants and, in the case of
               Certificated Warrants, return to the Registered Holder that
               submitted such Notice of Exercise, by first class mail, the
               Warrant Certificates evidencing such Warrants, or, in the
               case of Book-Entry Warrants (to the extent received in the
               case of Warrants held through CEDEL and Euroclear),
               redeliver the Warrants free through the facilities of the
               Depository to the account of such Participant and (C) notify
               the Company and the Spot Rate Reference Agent as to whether
               such Contingently Tendered Warrants will be subject to
               exercise;

                    (vi) by 5:00 p.m., New York City time, on the first New
               York Business Day following the New York Business Day that
               such Notice of Exercise has been received (or shall be
               deemed to have been received), (A) determine the sum of
               (1) the number of such Warrants not subject to the Limit
               Option (i.e., the number of Warrants determined pursuant to
               clause (iii)(C) above) plus (2) the number of such Warrants
               that are Contingently Tendered Warrants that will be subject
               to exercise notwithstanding the Limit Option (i.e., the
               number of Warrants so identified pursuant to clause (v)(B)
               above) (all of such Warrants, the "Exercised Warrants") and
               (B) notify the Company and the Spot Rate Reference Agent of
               the total number of Exercised Warrants so determined (if
               such number is zero, the Warrant Agent shall not take the
               actions required by clauses (vii) and (viii) with respect to
               such Notice of Exercise or the related Warrants);

                    (vii) calculate the Cash Settlement Value of the
               Exercised Warrants (excluding any Warrants held through
               CEDEL or Euroclear as to which timely delivery of the

               related Warrant has not been made) as of their Valuation
               Date in the manner set forth in Section 2.02(d) by no later
               than 3:00 p.m., New York City time, on the New York Business


               Day next succeeding the Valuation Date (unless the Cash
               Settlement Value shall be calculated by the Spot Rate
               Reference Agent); 

                    (viii) notify the Company (and such other parties (not
               to exceed two) as the Company shall designate in writing) by
               5:00 p.m., New York City time, on the New York Business Day
               next succeeding the Valuation Date of the Cash Settlement
               Value payable in respect of the Exercised Warrants, and send
               notices of confirmation substantially in the form included
               in Exhibit C-1 or Exhibit C-2 hereto, as appropriate, to the
               appropriate Registered Holder or Participant specifying
               therein the reference number assigned by the Warrant Agent
               to each accepted Notice of Exercise; and 

                    (ix) promptly deliver a copy of each Notice of Exercise
               to the Company and advise the Company of such other matters
               relating to the Exercised Warrants as the Company shall
               reasonably request.  Any notice to be given to the Company
               by the Warrant Agent pursuant to this Section 2.02 or
               Section 2.03 shall be by telephone (promptly confirmed in
               writing) or telecopy.

                    Except in the case of Warrants subject to automatic
          exercise, if on any Valuation Date the Cash Settlement Value for
          any Warrants then exercised would be zero, then the attempted
          exercise of such Warrants shall be void and of no effect and
          either (i) for Certificated Warrants, the Warrant Certificate
          evidencing such Warrants shall be promptly returned by the
          Warrant Agent to the Registered Holder by first class mail or
          (ii) for Book-Entry Warrants, the Warrants shall be transferred
          by the Warrant Agent back to the Participant that submitted them
          free on the records of the Depository (to the extent received in
          the case of Warrants held through CEDEL or Euroclear) and, in
          either case, such Warrantholder shall be permitted to re-exercise
          such Warrants prior to the Expiration Date or the Delisting Date,
          as the case may be.

                    (c)  Provided that the Company has made adequate funds
          available to the Warrant Agent in a timely manner, which shall in
          no event be later than 3:00 p.m., New York City time, on the
          fifth New York Business Day following a Valuation Date (the
          "Settlement Date"), the Warrant Agent will be responsible for
          making its payment available either (A) for Certificated
          Warrants, to each appropriate Registered Holder in the form of a
          cashier's check or an official bank check, or (in the case of
          payments of at least $100,000) by wire transfer to a U.S. dollar
          account maintained by such Registered Holder in the United States
          (at such Registered Holder's election as specified in the appli-
          cable Notice of Exercise), after 3:00 p.m., New York City time,
          but prior to the close of business, on such Settlement Date or

          (B) for Book-Entry Warrants, to each appropriate Participant by
          wire transfer to a U.S. dollar account maintained by such
          Participant in the United States, after 3:00 p.m., New York City
          time, but prior to the close of business, on such Settlement
          Date.  For either clause (A) or (B) above, such payment shall be
          in the amount of the aggregate Cash Settlement Value in respect
          of the Warrant Certificates or Warrants that were delivered to
          the Warrant Agent (together with the related Notice of Exercise)
          as provided in Sections 2.01 and 2.02(a) and (b).

                    (d)  The "Cash Settlement Value" of a Warrant will
          equal an amount in U.S. dollars (rounded down to the nearest
          cent) which is the greater of (i) zero and (ii) the amount
          computed by subtracting from U.S. $100 an amount equal to the
          product of U.S. $100 times a fraction, the numerator of which is
          yen 83.25 per U.S. $1.00 and the denominator of which is the Spot
          Rate.  The "Spot Rate" on any Valuation Date will be determined
          by the Spot Rate Reference Agent and will equal (i) the noon
          buying rate per U.S. $1.00 in The City of New York on such
          Valuation Date for cable transfers in Japanese yen as certified
          for customs purposes by the Federal Reserve Bank of New York (the
          "Noon Buying Rate"), as reported on page 1FEE of The Reuter
          Monitor Money Rates Service (or such page as may replace that
          page), or (ii) if the Noon Buying Rate does not appear on such
          page by 1:00 p.m., New York City time, on such Valuation Date,
          the Noon Buying Rate on such Valuation Date as otherwise
          announced by the Federal Reserve Bank of New York, or (iii) if
          the Federal Reserve Bank of New York has not quoted such Noon
          Buying Rate by 1:30 p.m., New York City time, on such Valuation
          Date, the offered spot rate of Japanese yen per U.S. $1.00 on
          such Valuation Date, which offered spot rate shall be calculated
          by the Spot Rate Reference Agent by (A) obtaining at
          approximately 1:30 p.m., New York City time, a quote for a
          transaction amount approximately equivalent to U.S. $100 times
          the aggregate number of Warrants which were properly exercised on
          the related Exercise Date from each of five leading market makers
          (other than the Spot Rate Reference Agent) in the foreign
          exchange markets for Japanese yen selected by the Spot Rate
          Reference Agent, (B) discarding the highest and lowest quotes
          obtained and (C) averaging the three remaining quotes to
          determine such offered spot rate.

                    The Spot Rate used to determine the Cash Settlement
          Value on any Valuation Date will be rounded to the second decimal
          place (e.g., 84.00), rounding up if the next succeeding decimal
          place, without regard to rounding, is five or higher.  Any such
          Cash Settlement Value will be rounded downwards, if necessary, to
          the nearest cent.  In no event shall a Warrantholder be entitled


          to any interest on any Cash Settlement Value.

                    References in this Agreement to "U.S. dollars" or "U.S.
          $" are to the lawful currency of the United States of America. 
          References to "Japanese yen" or "yen" are to the lawful currency of
          Japan.

                    (e)  In the event a Global Warrant Certificate is
          issued, the Warrant Agent shall cause its records, which may be
          kept electronically, to be marked to reflect the reduction in the
          number of Warrants represented by the Global Warrant Certificate
          by the number of Warrants that were delivered to the Warrant
          Account and for which payment has been made as provided in
          Section 2.02(c) promptly after such delivery and payment.  Absent
          manifest error, the Warrant Agent's records shall be conclusive
          evidence of such matters.

                    (f)  The Company has appointed PaineWebber and
          PaineWebber accepts such appointment, to be the Company's Spot
          Rate Reference Agent to make such calculations as may be
          required, including, without limitation, calculation of the Spot
          Rate and any Reference Rate.  The Spot Rate Reference Agent shall
          timely communicate each Spot Rate and any Reference Rate to the
          Warrant Agent.  The Spot Rate Reference Agent shall act as an
          independent expert and not as an agent of the Company, and,
          unless otherwise provided by this Agreement, its calculations and
          determinations under this Agreement shall, absent manifest error,
          be final and binding on the Company, the Warrant Agent, the
          Warrantholders and any Participant.  Any such calculations will
          be made available to a Warrantholder for inspection at the
          Warrant Agent's Office.

                    The Company agrees, for the benefit of the War-
          rantholders from time to time of the Warrants, that there shall
          at all times be a Spot Rate Reference Agent hereunder until all
          the Warrants are no longer outstanding or until monies for the
          payment of all outstanding Warrants, if any, shall have been paid
          to the Warrant Agent and shall have been returned to the Company
          as provided in Section 2.06, whichever occurs earlier. 
          Resignation, removal and appointment of the Spot Rate Reference
          Agent shall be in accordance with the procedures set forth for
          the resignation, removal and appointment of the Warrant Agent, as
          provided in Section 5.03, except that a successor Spot Rate
          Reference Agent need not be a banking institution with offices
          south of Chambers Street in the Borough of Manhattan, The City of
          New York, and may only be appointed if such successor has been


          nominated by the Company and approved by the predecessor Spot
          Rate Reference Agent.

                    The Company agrees promptly to pay the Spot Rate
          Reference Agent the compensation to be agreed upon with the
          Company for all services rendered by the Spot Rate Reference
          Agent hereunder.  The Company also agrees to indemnify the Spot
          Rate Reference Agent for, and to hold it harmless against, any
          loss, liability, cost or expense (including reasonable attorneys'
          fees and expenses) incurred by the Spot Rate Reference Agent by
          reason of its being made a party to a suit or claim arising out
          of this Agreement; provided, however, that such indemnity shall
          in no event apply to the extent that any such loss, liability,
          cost or expense is a result of the negligence, bad faith or
          breach of this Agreement on its part in connection with the

          
                                          15  
 
<PAGE>




          services rendered by it hereunder.  The indemnity obligation of
          the Company shall continue notwithstanding the termination of
          this Agreement or the resignation or removal of the Spot Rate
          Reference Agent.

                    (g)  Except in the event of an automatic exercise (as
          described in Section 2.03 below), in connection with any exercise
          of Warrants, the related Notice of Exercise may specify that such
          exercise is subject to the condition that the Spot Rate used to
          determine the Cash Settlement Value of such Warrants shall not
          have declined by five or more Japanese yen per U.S. dollar from
          the Reference Rate for such Warrants.  "Reference Rate", with
          respect to any Contingently Tendered Warrants, means the Spot
          Rate on the New York Business Day that such Notice of Exercise
          has been received (or shall be deemed to have been received). 
          The option of a Warrantholder to condition an exercise of
          Warrants as provided in this Section 2.02(g) is herein referred
          to as the "Limit Option".  If a Warrantholder elects the Limit
          Option in connection with any exercise of Warrants, the following
          provisions shall apply:

                    (i)  To be valid, such election must be specified in
               the related Notice of Exercise.  Each of the Warrant Agent
               and the Company shall be entitled to rely conclusively on
               such Notice of Exercise, as received by the Warrant Agent,
               in determining whether such election has been validly made. 
               In connection with any exercise of 500 or more Warrants, a
               Warrantholder may elect to subject only a portion of such
               Warrants to the Limit Option; provided, however, that the
               number of such Warrants subject to the Limit Option and the


               number of such Warrants not subject to the Limit Option
               shall in each case not be less than 500.  Registered Holders
               and Participants shall be required to certify that the
               number of Warrants exercised on behalf of any Warrantholder
               pursuant to the related Notice of Exercise that is subject
               to the Limit Option is not less than 500.

                    (ii)  The Reference Rate shall be determined by the
               Spot Rate Reference Agent, which determination shall be
               conclusive and binding for all purposes relating to such
               exercise.

                    (iii)  In the event that the Spot Rate for the first
               New York Business Day following the New York Business Day
               that such Notice of Exercise has been received (or shall be
               deemed to have been received) (i.e., for the day that, but
               for the provisions of this Section 2.02(g), would be the
               Valuation Date for such Warrants) has declined by five or
               more Japanese yen per U.S. dollar from the Reference Rate
               for such Warrants, such Warrants (A) shall not be subject to
               exercise and shall be treated for all purposes of this
               Agreement and the Warrant Certificates and Global Warrant
               Certificate as if the related Notice of Exercise had never
               been received by the Warrant Agent, and (B) shall not

          
                                          16

               constitute "Exercised Warrants" for purposes of
               Section 2.02(b).  If such Spot Rate has not declined by five
               or more Japanese yen per U.S. dollar from such Reference
               Rate, such Warrants shall be subject to exercise as provided
               in this Section 2.02 and shall be deemed to be "Exercised
               Warrants" for such purposes.  The Warrant Agent's
               determination shall be conclusive and binding for all
               purposes relating to such Warrants.

                    SECTION 2.03.  Automatic Exercise of Warrants.  All
          Warrants for which the Warrant Agent has not received a Notice of
          Exercise in proper form at or prior to 3:00 p.m., New York City
          time, on the earlier of (i) the New York Business Day preceding
          the Expiration Date and (ii) the Delisting Date, or for which the
          Warrant Agent has received a Notice of Exercise in proper form
          but with respect to which timely delivery of the relevant
          Warrants has not been made, will be deemed automatically
          exercised on such date without any requirement of a Notice of
          Exercise to the Warrant Agent.  The Exercise Date for such
          Warrants shall be the Expiration Date or the Delisting Date, as
          the case may be, and the Valuation Date for such Warrants shall


          be the first New York Business Day following the Exercise Date
          for such Warrants. 

                    The Warrant Agent shall by 5:00 p.m., New York City
          time, on the Expiration Date or the Delisting Date, as the case
          may be, notify the Company (and such other parties (not to exceed
          two) as the Company shall designate in writing) of the number of
          Warrants to be automatically exercised on such day.  The Warrant
          Agent shall (i) by 3:00 p.m., New York City time, on the New York
          Business Day next succeeding the Valuation Date, calculate for
          such Warrants the Cash Settlement Value (in the manner provided
          in Section 2.02(d)) of the Warrants to be automatically exer-
          cised, (ii) by 5:00 p.m., New York City time, on the New York
          Business Day next succeeding such Valuation Date, notify the
          Company (and such other parties (not to exceed two) as the
          Company shall designate in writing) of the Cash Settlement Value
          payable in respect of such exercised Warrants and (iii) advise
          the Company of such other matters relating to the exercised
          Warrants as the Company shall reasonably request.

                    With respect to Certificated Warrants subject to
          automatic exercise, the Company shall make available to the
          Warrant Agent, not later than 3:00 p.m., New York City time, on
          the fourth New York Business Day following the Valuation Date for
          automatically exercised Warrants (the "Automatic Settlement
          Date"), funds in an amount equal to, and for the payment of, the
          aggregate Cash Settlement Value of such Warrants.  Subject to
          such funds having been made available as provided in the
          preceding sentence, the Warrant Agent will be responsible for
          making its payment available to each appropriate Registered
          Holder in the form of a cashier's check or an official bank
          check, or (in the case of payments of at least $100,000) by wire
          transfer to a U.S. dollar account maintained by such Registered

          Holder in the United States (at such Registered Holder's
          election), after 3:00 p.m., New York City time, but prior to the
          close of business, on the Automatic Settlement Date, against
          receipt by the Warrant Agent at the Warrant Agent's Office from
          such Registered Holder of its Warrant Certificates.  Such payment
          shall be equal to the aggregate Cash Settlement Value of the
          Warrants evidenced by such Warrant Certificates.  All Warrant
          Certificates delivered to the Warrant Agent shall thereafter be
          promptly canceled by the Warrant Agent.

                    With respect to Book-Entry Warrants subject to
          automatic exercise, the Company shall make available to the


          Warrant Agent, not later than 3:00 p.m., New York City time, on
          the Automatic Settlement Date, funds in an amount equal to, and
          for the payment of, the aggregate Cash Settlement Value of such
          Warrants.  Subject to such funds having been made available as
          provided in the preceding sentence, the Warrant Agent will be
          responsible for making funds available to the Depository in
          accordance with procedures agreed upon between the Depository and
          the Warrant Agent, against receipt of the Global Warrant Certifi-
          cate, after 3:00 p.m., New York City time, but prior to the close
          of business, on the Automatic Settlement Date, such funds to be
          in an amount equal to the aggregate Cash Settlement Value of the
          Book-Entry Warrants subject to such automatic exercise.

                    The Company will advise the Warrant Agent as soon as
          practicable of the date of any expected delisting or permanent
          suspension of trading of the Warrants and will immediately inform
          the Warrant Agent after the Company has received notice that such
          delisting or suspension has occurred, but in no event will notice
          of such delisting or suspension be given to the Warrant Agent
          later than 9:30 a.m., New York City time, on the New York
          Business Day following the date that such delisting or suspension
          occurs.  The Company will use its best efforts to notify the
          Warrantholders, or cause the Warrantholders to be notified, as
          promptly as practicable of any expected delisting or suspension
          of trading of the Warrants.

                    SECTION 2.04.  Limitation of Number of Exercisable
          Warrants.  All exercises of Warrants (other than on the
          Expiration Date or the Delisting Date) shall be subject, at the
          Company's option, to the limitation that not more than
          1,000,000 Warrants in total may be exercised on any Exercise Date
          and not more than 250,000 Warrants may be exercised by or on
          behalf of any person or entity, either individually or in concert
          with any other person or entity, on any Exercise Date.  If any
          New York Business Day would otherwise, under the terms hereof, be
          the Exercise Date in respect of more than 1,000,000 Warrants,
          then upon the Company's exercising such option (by giving notice
          thereof to the Warrant Agent not later than 5:00 p.m., New York
          City time, on the New York Business Day immediately following
          such Exercise Date), 1,000,000 of such Warrants shall be deemed
          exercised on such Exercise Date (selected by the Warrant Agent on
          a pro rata basis, but if, as a result of such pro rata selection,

          
                                          18  
 
<PAGE>




          any Registered Holders would be deemed to have exercised less
          than 500 Warrants, then the Warrant Agent shall first select
          additional Warrants of such Registered Holders so that no such


          Registered Holder shall be deemed to have exercised less than
          500 Warrants), and the remainder of such Warrants (the "Remaining
          Warrants") shall be deemed exercised on the following New York
          Business Day (notwithstanding the minimum exercise requirement of
          Section 2.01 and subject to successive applications of this
          Section 2.04); provided, however, that any Remaining Warrant in
          respect of which a Notice of Exercise was delivered on a given
          Notice Date shall be deemed exercised before any other Warrants
          in respect of which a Notice of Exercise was delivered on a later
          Notice Date.  If any individual Warrantholder attempts to
          exercise more than 250,000 Warrants on any New York Business Day,
          then at the Company's election (as notified to the Warrant Agent
          by giving notice thereof to the Warrant Agent not later than 5:00
          p.m., New York City time, on the New York Business Day following
          such New York Business Day) 250,000 of such Warrants shall be
          deemed exercised on such New York Business Day and the remainder
          shall be deemed exercised on the following New York Business Day
          (subject to successive applications of this Section 2.04).  The
          date on which any Warrant is deemed exercised under the preceding
          sentences shall for all purposes of this Agreement be the
          "Exercise Date" in respect of such Warrant.

                    SECTION 2.05.  Covenant of the Company.  The Company
          covenants, for the benefit of the Warrantholders, that it will
          not seek the delisting of the Warrants from, or suspension of
          their trading on, the NYSE unless the Company has, at the same
          time, arranged for listing on another United States national
          securities exchange.

                    SECTION 2.06.  Return of Money Held Unclaimed for Two
          Years.  Except as otherwise provided herein, any money deposited
          with or paid to the Warrant Agent for the payment of the Cash
          Settlement Value of any Warrants and not applied but remaining
          unclaimed for two years after the date upon which such Cash
          Settlement Value shall have become due and payable shall be
          repaid by the Warrant Agent to the Company and the holders of
          such Warrants shall thereafter look only to the Company for any
          payment which such holders may be entitled to collect and all
          liability of the Warrant Agent with respect to such money shall
          thereupon cease; provided, however, that the Warrant Agent,
          before making any such repayment, may at the expense of the
          Company notify (i) in the case of Certificated Warrants, the
          Registered Holders or (ii) in the case of Book-Entry Warrants,
          the Participants concerned, that said money has not been so
          applied and remains unclaimed and that after a date named in the
          notification any unclaimed balance of said money then remaining
          will be returned to the Company.

                    SECTION 2.07.  Return of Global Warrant Certificate. 
          In the event a Global Warrant Certificate is issued, at such time
          as all of the Warrants evidenced by such Certificate have been

          exercised (including pursuant to an automatic exercise) and all
          payments to the Participants made as provided herein, the Warrant
          Agent shall destroy the canceled Global Warrant Certificate
          (unless instructed by the Company to deliver the Global Warrant
          Certificate to the Company) and shall provide a certificate of
          destruction to the Company.

                               RIGHTS OF WARRANTHOLDERS

                    SECTION 3.01.  Warrantholder of Warrant May Enforce
          Rights.  Notwithstanding any of the provisions of this Agreement,
          any Warrantholder, without the consent of the Warrant Agent, may,
          in and for its own behalf, enforce, and may institute and
          maintain, any suit, action or proceeding against the Company
          suitable to enforce, or otherwise in respect of, its right to

          this Agreement.

                          WARRANTS ACQUIRED BY THE COMPANY;
                                   PAYMENT OF TAXES

                    SECTION 4.01.  Warrants Acquired by the Company.  In
          the event the Company shall purchase or otherwise acquire
          Warrants, such Warrants may, at the option of the Company, be
          (i) in the case of Certificated Warrants, delivered to the
          Warrant Agent, and if so delivered, the Warrant Agent shall
          promptly note the cancellation of such Warrants on the records of
          the Warrant Agent or (ii) in the case of Book-Entry Warrants,
          surrendered free through a Participant to the Depository for
          credit to the account of the Warrant Agent maintained at the
          Depository, and if so credited, the Warrant Agent shall promptly
          note the cancellation of such Warrants by notation on the records
          of the Warrant Agent.  In the case of Book-Entry Warrants, such
          Warrants may also, at the option of the Company, be resold by the
          Company directly or to or through any of its affiliates in lieu
          of being surrendered to the Depository.  No Warrant Certificate
          shall be countersigned in lieu of or in exchange for any Warrant
          which is canceled as provided herein, except as otherwise
          expressly permitted by this Agreement.

                    Any canceled Warrant Certificate held by the Warrant


          Agent under this Agreement shall be destroyed by the Warrant
          Agent unless otherwise directed by the Company, and the Warrant
          Agent shall deliver a certificate of destruction to the Company
          evidencing the same.

                    SECTION 4.02.  Payment of Taxes.  The Company will pay
          all stamp, withholding and other duties, if any, attributable to
          the initial issuance of Warrants; provided, however, that,
          anything in this Agreement to the contrary notwithstanding, the
          Company shall not be required to pay any tax or other
          governmental charge which may be payable in respect of any
          transfer involving any beneficial or record interest in, or
          ownership interest of, any Warrants, Warrant Certificates or
          Global Warrant Certificate, which tax or other governmental
          charge shall be paid by the appropriate Warrantholder or
          Registered Holder.

                             CONCERNING THE WARRANT AGENT

                    SECTION 5.01.  Warrant Agent.  (a)  The Company hereby
          appoints Citibank, N.A. ("Citibank") as Warrant Agent of the
          Company in respect of the Warrants upon the terms and subject to
          the conditions set forth herein; and Citibank hereby accepts such
          appointment.  The Warrant Agent shall have the powers and
          authority granted to and conferred upon it in this Agreement and
          such further powers and authority to act on behalf of the Company
          as the Company may hereafter grant to or confer upon it.  All of
          the terms and provisions with respect to such powers and
          authority contained in any Warrant Certificates or the Global
          Warrant Certificate are subject to and governed by the terms and
          provisions hereof.

                    (b)  Citibank covenants and agrees to maintain an
          office, staffed by qualified personnel, with adequate facilities
          for the discharge of its responsibilities under this Agreement,
          including, without limitation, the computation of the Cash
          Settlement Value and the timely settlement of the Warrants upon
          exercise thereof.

                    SECTION 5.02.  Conditions of Warrant Agent's Obliga-
          tions.  The Warrant Agent accepts its obligations herein set


          forth upon the terms and conditions hereof, including the
          following, to all of which the Company agrees and to all of which
          the rights hereunder of the holders from time to time of the
          Warrants shall be subject:

                    (a)  The Company agrees promptly to pay the Warrant
               Agent the compensation to be agreed upon with the Company
               for all services rendered by the Warrant Agent and to
               reimburse the Warrant Agent for its reasonable out-of-pocket
               expenses (including attorneys' fees and expenses) incurred
               by the Warrant Agent without negligence, bad faith or breach
               of this Agreement on its part in connection with the
               services rendered by it hereunder.  The Company also agrees
               to indemnify the Warrant Agent for, and to hold it harmless
               against, any loss, liability or expense (including

          
                                          21

               reasonable attorneys' fees and expenses) incurred without
               negligence, bad faith or breach of this Agreement on the
               part of the Warrant Agent, arising out of or in connection
               with its acting as such Warrant Agent hereunder, as well as
               the reasonable costs and expenses of defending against any
               claim of liability in the premises.

                    (b)  In acting under this Agreement, the Warrant Agent
               is acting solely as agent of the Company and does not assume
               any obligation or relationship of agency or trust for or
               with any of the owners or holders of the Warrants.

                    (c)  The Warrant Agent may consult with counsel sat-
               isfactory to it, and the opinion of such counsel shall be
               full and complete authorization and protection in respect of
               any action taken, suffered or omitted by it hereunder in
               good faith and in accordance with the opinion of such
               counsel.

                    (d)  The Warrant Agent shall be protected and shall
               incur no liability for or in respect of any action taken or
               thing suffered by it in reliance upon any notice, direction,
               consent, certificate, affidavit, statement or other paper or
               document reasonably believed by it to be genuine and to have
               been presented or signed by the proper parties.

                    (e)  The Warrant Agent, and its officers, directors and
               employees, may become the owner of, or acquire any interest
               in, any Warrants or other obligations of the Company, with
               the same rights that it or they would have if it were not


               the Warrant Agent hereunder and, to the extent permitted by
               applicable law, it or they may engage or be interested in
               any financial or other transaction with the Company and may
               act on, or as depository, trustee or agent for, any
               committee or body of holders of Warrants or other
               obligations of the Company as freely as if it were not the
               Warrant Agent hereunder.

                    (f)  The Warrant Agent shall not be under any liability
               for interest on any monies at any time received by it
               pursuant to any of the provisions of this Agreement nor
               shall it be obligated to segregate such monies from other
               monies held by it, except as required by law.  The Warrant
               Agent shall not be responsible for advancing funds on behalf
               of the Company.

                    (g)  The Warrant Agent shall not be under any
               responsibility with respect to the validity or sufficiency
               of this Agreement or the execution and delivery hereof
               (except the due execution and delivery hereof by the Warrant
               Agent) or with respect to the validity or execution of the
               Warrant Certificates or the Global Warrant Certificate
               (except its countersignature thereof).

                    (h)  The recitals contained herein and in the Warrant
               Certificates or the Global Warrant Certificate (except as to
               the Warrant Agent's countersignature thereon) shall be taken
               as the statements of the Company, and the Warrant Agent
               assumes no responsibility for the correctness of the same.

                    (i)  The Warrant Agent shall be obligated to perform
               such duties as are herein specifically set forth, and no
               implied duties or obligations shall be read into this
               Agreement against the Warrant Agent.  The Warrant Agent
               shall not be under any obligation to take any action
               hereunder likely to involve it in any expense or liability,
               the payment of which is not, in its reasonable opinion,
               assured to it.  The Warrant Agent shall not be accountable
               or under any duty or responsibility for the application by
               the Company of any proceeds.  The Warrant Agent shall have
               no duty or responsibility in case of any default by the
               Company in the performance of its covenants or agreements
               contained in any Warrant Certificate or the Global Warrant
               Certificate or in the case of the receipt of any written
               demand from a holder of a Warrant with respect to such


               default, including, without limiting the generality of the
               foregoing, any duty or responsibility to initiate or attempt
               to initiate any proceedings at law or otherwise or, except
               as provided in Section 6.02 hereof, to make any demand upon
               the Company.

                    SECTION 5.03.  Resignation and Appointment of
          Successor.  (a)  The Company agrees, for the benefit of the hold-
          ers from time to time of the Warrants, that there shall at all
          times be a Warrant Agent hereunder until all the Warrants are no
          longer outstanding or until monies for the payment of all
          outstanding Warrants, if any, shall have been paid to the Warrant
          Agent and shall have been returned to the Company as provided in
          Section 2.06, whichever occurs earlier.

                    (b)  The Warrant Agent may at any time resign as such
          agent by giving written notice to the Company of such intention
          on its part, specifying the date on which its desired resignation
          shall become effective, subject to the appointment of a successor
          Warrant Agent and acceptance of such appointment by such
          successor Warrant Agent as hereinafter provided.  The Warrant
          Agent hereunder may be removed at any time by the filing with it
          of an instrument in writing signed by or on behalf of the Company
          and specifying such removal and the date when it shall become
          effective.  Such resignation or removal shall take effect upon
          the appointment by the Company, as hereinafter provided, of a
          successor Warrant Agent (which shall be a banking institution
          organized under the laws of the United States of America or one
          of the states thereof and having an office south of Chambers
          Street in the Borough of Manhattan, The City of New York) and the
          acceptance of such appointment by such successor Warrant Agent. 
          In the event a successor Warrant Agent has not been appointed and
          accepted its duties within 90 days of the Warrant Agent's notice

          
                                          23

          of resignation, the Warrant Agent may apply to any court of
          competent jurisdiction for the designation of a successor Warrant
          Agent.  The obligation of the Company under Section 5.02(a) shall
          continue to the extent set forth therein notwithstanding the
          resignation or removal of the Warrant Agent.

                    (c)  In case at any time the Warrant Agent shall give
          notice of its intent to resign, or shall be removed, or shall
          become incapable of acting, or shall be adjudged a bankrupt or
          insolvent, or make an assignment for the benefit of its
          creditors, or consent to the appointment of a receiver or
          custodian of all or any substantial part of its property, or


          shall admit in writing its inability to pay or meet its debts as
          they mature, or if a receiver or custodian of it or of all or any
          substantial part of its property shall be appointed, or if any
          public officer shall have taken charge or control of the Warrant
          Agent or of its property or affairs for the purpose of
          rehabilitation, conservation or liquidation, a successor Warrant
          Agent, qualified as aforesaid, shall be promptly appointed by the
          Company by an instrument in writing, filed with the successor
          Warrant Agent.  Upon the appointment as aforesaid of a successor
          Warrant Agent and acceptance by the latter of such appointment,
          the Warrant Agent so superseded shall cease to be Warrant Agent
          hereunder.

                    (d)  Any successor Warrant Agent appointed hereunder
          shall execute, acknowledge and deliver to its predecessor and to
          the Company an instrument accepting such appointment hereunder,
          and thereupon such successor Warrant Agent, without any further
          act, deed or conveyance, shall become vested with all the
          authority, rights, powers, trust, immunities, duties and
          obligations of such predecessor with like effect as if originally
          named as Warrant Agent hereunder, and such predecessor, upon
          payment of its charges and disbursements then unpaid, shall
          thereupon become obligated to transfer, deliver and pay over, and
          such successor Warrant Agent shall be entitled to receive, all
          monies, securities and other property on deposit with or held by
          such predecessor (including, without limitation, the Warrant Reg-
          ister), as Warrant Agent hereunder.

                    (e)  Any corporation into which the Warrant Agent
          hereunder may be merged or converted or any corporation with
          which the Warrant Agent may be consolidated, or any corporation
          resulting from any merger, conversion or consolidation to which
          the Warrant Agent shall be a party, or any corporation to which
          the Warrant Agent shall sell or otherwise transfer all or
          substantially all the corporate trust assets and business of the
          Warrant Agent, provided that it shall be qualified as aforesaid,
          shall be the successor Warrant 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.

                                    MISCELLANEOUS



                    SECTION 6.01.  Amendment.  (a)  This Agreement and the
          terms of the Warrants may be amended by the Company, the Warrant
          Agent and the Spot Rate Reference Agent, without the consent of
          the Warrantholders, for the purpose of curing any ambiguity, or
          of curing, correcting or supplementing any defective or
          inconsistent provision contained herein or therein or in any
          other manner which the Company may deem necessary or desirable
          and which, as determined by the Company in its sole discretion,
          will not adversely affect the interests of the holders of the
          Warrants.  Notwithstanding anything in this Section 6.01 to the
          contrary, this Agreement may not be amended to provide for the
          countersigning by the Warrant Agent of Warrant Certificates evi-
          dencing in the aggregate in excess of 1,050,000 Warrants unless
          and until the Warrant Agent has received notice from the NYSE or
          any successor United States national securities exchange that the
          additional Warrants in excess of 1,050,000 have been approved for
          listing on such exchange.

                    (b)  The Company, the Warrant Agent and the Spot Rate
          Reference Agent may modify or amend this Agreement, with the
          consent of Warrantholders holding not less than a majority in
          number of the then outstanding Warrants affected by such mod-
          ification or amendment, for any purpose; provided, however, that
          no such modification or amendment that increases the Strike Rate,
          shortens the period of time during which the Warrants may be
          exercised, or otherwise materially and adversely affects the
          exercise rights of the Warrantholders or reduces the percentage
          of the number of outstanding Warrants, the consent of whose
          holders is required for modification or amendment of this
          Agreement, may be made without the consent of each Warrantholder
          affected thereby.

                    SECTION 6.02.  Notices and Demands to the Company, the
          Warrant Agent and the Spot Rate Reference Agent.  If the Warrant
          Agent or the Spot Rate Reference Agent shall receive any notice
          or demand addressed to the Company by any Warrantholder pursuant
          to the provisions of this Agreement, the Warrant Agent or the
          Spot Rate Reference Agent, as the case may be, shall promptly
          forward such notice or demand to the Company.

                    SECTION 6.03.  Addresses for Notices.  Any commu-
          nications to the Warrant Agent with respect to this Agreement

                    SECTION 6.06.  Persons Having Rights Under This
          Agreement.  Nothing in this Agreement expressed or implied and
          nothing that may be inferred from any of the provisions hereof is

                            U.S. Dollar Increase Warrants
                                 on the Japanese Yen

                               Expiring April 30, 1996


                    This Warrant Certificate certifies that ______________,
          or registered assigns, is the registered holder of _________ U.S.
          Dollar Increase Warrants on the Japanese Yen Expiring April 30,
          1996 (the "Warrants").  Upon receipt by the Warrant Agent of this
          Warrant Certificate and the Notice of Exercise on the reverse
          hereof (or a Notice of Exercise in substantially identical form
          delivered herewith), duly completed and executed, at the offices
          of the Warrant Agent in the Borough of Manhattan, The City of
          New York, each Warrant entitles the beneficial owner thereof
          (each a "Warrantholder") to receive, subject to the conditions
          set forth herein and in the Warrant Agreement, from Paine Webber
          Group Inc. (the "Company") the cash settlement value in
          U.S. dollars (rounded down to the nearest cent) (the "Cash
          Settlement Value") which is the greater of (i) zero and (ii) the
          amount computed by subtracting from U.S. $100 an amount equal to
          the product of U.S. $100 times a fraction, the numerator of which
          is yen 83.25 per U.S. $1.00 and the denominator of which is the Spot
          Rate (as defined herein).  In no event shall a Warrantholder be
          entitled to any interest on any Cash Settlement Value.

                    Subject to the terms of the Warrant Agreement, each
          Warrant may be irrevocably exercised, in whole but not in part,
          at or prior to 3:00 p.m., New York City time, on any New York
          Business Day from its date of issuance until 3:00 p.m., New York
          City time, on the earlier of (i) the New York Business Day
          immediately preceding April 30, 1996 (the "Expiration Date") and
          (ii) the Delisting Date (as defined herein), after which time the
          Warrants shall expire and all Warrants evidenced hereby shall be
          automatically exercised and shall otherwise be void.  Except in
          the event of automatic exercise of the Warrants as set forth
          herein and in the Warrant Agreement, or as otherwise provided in
          the Warrant Agreement, not fewer than 500 Warrants may be
          exercised by or on behalf of any one Warrantholder at any one
          time.

                    Reference is hereby made to the further provisions of
          this Warrant Certificate set forth on the reverse hereof and such
          further provisions shall for all purposes have the same effect as
          though fully set forth at this place.

                    This Warrant Certificate shall not be valid unless


          countersigned by the Warrant Agent.

                                      [REVERSE]

                               PAINE WEBBER GROUP INC.

                    The Warrants evidenced by this Warrant Certificate are


          part of a duly authorized issue of Warrants issued by the Company
          pursuant to a Warrant Agreement, dated as of May 1, 1995 (the
          "Warrant Agreement"), among the Company, Citibank, N.A. (the
          "Warrant Agent") and PaineWebber Incorporated (the "Spot Rate
          Reference Agent") and is subject to the terms and provisions
          contained in the Warrant Agreement, to all of which terms and
          provisions each Warrantholder consents by acceptance of this
          Warrant Certificate and which Warrant Agreement is hereby
          incorporated by reference in and made a part of this Warrant
          Certificate.  A copy of the Warrant Agreement is on file at the
          Warrant Agent's Office (as defined herein).

                    The Warrants constitute direct, unconditional and
          unsecured obligations of the Company and rank on a parity with
          the Company's other unsecured contractual obligations and with
          the Company's unsecured and unsubordinated debt.

                    Subject to the provisions hereof and of the Warrant
          Agreement, each Warrant may be irrevocably exercised, in whole
          but not in part, at or prior to 3:00 p.m., New York City time, on
          any New York Business Day (as defined herein) from its date of
          issuance until 3:00 p.m., New York City time, on the earlier of
          (i) the New York Business Day immediately preceding the
          Expiration Date and (ii) the Delisting Date (as defined herein). 
          The holder of Warrants evidenced by this Warrant Certificate may
          exercise them by surrendering this Warrant Certificate and
          attached Notice of Exercise (or a Notice of Exercise in
          substantially identical form), duly completed and executed, to
          the Warrant Agent's offices in the Borough of Manhattan, The City
          of New York (the "Warrant Agent's Office"), which are, on the
          date hereof, located at 111 Wall Street, New York, New York
          10043, Attention:  Corporate Trust Department.  Except in the
          event of automatic exercise of the Warrants as set forth herein
          and in the Warrant Agreement, or as otherwise provided in the
          Warrant Agreement, not fewer than 500 Warrants may be exercised
          by or on behalf of any one Warrantholder at any one time.

                    The "Cash Settlement Value" of a Warrant will equal an
          amount in U.S. dollars (rounded down to the nearest cent) which
          is the greater of (i) zero and (ii) the amount computed by
          subtracting from U.S. $100 an amount equal to the product of U.S.
          $100 times a fraction, the numerator of which is yen 83.25 per U.S.
          $1.00 and the denominator of which is the Spot Rate.  The "Spot
          Rate" on any Valuation Date will be determined by the Spot Rate
          Reference Agent and will equal (a) the noon buying rate per U.S.
          $1.00 in The City of New York on such Valuation Date for cable
          transfers in Japanese yen as certified for customs purposes by

          the Federal Reserve Bank of New York (the "Noon Buying Rate"), as
          reported on page 1FEE of The Reuter Monitor Money Rates Service
          (or such page as may replace that page), or (b) if the Noon
          Buying Rate does not appear on such page by 1:00 p.m., New York
          City time, on such Valuation Date, the Noon Buying Rate on such
          Valuation Date as otherwise announced by the Federal Reserve Bank
          of New York, or (c) if the Federal Reserve Bank of New York has
          not quoted such Noon Buying Rate by 1:30 p.m., New York City
          time, on such Valuation Date, the offered spot rate of Japanese
          yen per U.S. $1.00 on such Valuation Date, which offered spot
          rate shall be calculated by the Spot Rate Reference Agent by
          (1) obtaining at approximately 1:30 p.m., New York City time, a
          quote for a transaction amount approximately equivalent to U.S.
          $100 times the aggregate number of Warrants which were properly
          exercised on the related Exercise Date from each of five leading
          market makers (other than the Spot Rate Reference Agent) in the
          foreign exchange markets for Japanese yen selected by the Spot
          Rate Reference Agent, (2) discarding the highest and lowest
          quotes obtained and (3) averaging the three remaining quotes to
          determine such offered spot rate.

                    The Spot Rate used to determine the Cash Settlement
          Value on any Valuation Date will be rounded to the second decimal
          place (e.g., 84.00), rounding up if the next succeeding decimal
          place, without regard to rounding, is five or higher.  Any such
          Cash Settlement Value will be rounded downwards, if necessary, to
          the nearest cent.

                    The Company has appointed PaineWebber Incorporated
          ("PaineWebber") to be its Spot Rate Reference Agent to make such
          calculations as may be required upon the occurrence of certain
          circumstances, as described in the Warrant Agreement and herein,
          including, without limitation, calculation of the Spot Rate and
          any Reference Rate.  The Spot Rate Reference Agent shall act as
          an independent expert and not as an agent of the Company, and,
          unless otherwise provided by the Warrant Agreement, its
          calculations and determinations under the Warrant Agreement and
          this Warrant Certificate shall, absent manifest error, be final
          and binding on the Company, the Warrant Agent and the
          Warrantholders.

                    Subject to the Warrant Agreement and this Warrant
          Certificate, and except in the case of exercise (whether
          automatic or by Notice of Exercise) on the Expiration Date or the
          Delisting Date, or in the case of a postponement due to there
          being exercised a number of Warrants in excess of the maximum
          permitted number on a given day, the valuation date (the "Valua-
          tion Date") for a Warrant shall be the New York Business Day next
          succeeding the New York Business Day (the "Exercise Date") on
          which the Warrant Agent has received the Warrant Certificate
          representing such Warrant, with the Notice of Exercise below (or
          a Notice of Exercise in substantially identical form delivered


          herewith), duly completed and executed, at or prior to 3:00 p.m.,
          New York City time (the "Notice Date"); and if the Warrant Agent

          
                                         A-4

          shall receive any such Warrant Certificate after 3:00 p.m.,
          New York City time, on such date, then such Warrant Certificate
          shall be deemed to have been received at or prior to 3:00 p.m.,
          New York City time, on the next succeeding New York Business Day
          (which shall be considered the Notice Date), and in such event
          the Valuation Date shall be the New York Business Day following
          the New York Business Day on which the Warrant Agent is deemed to
          have received such Warrant Certificate together with the Notice
          of Exercise.  Any Warrant Certificate received after 3:00 p.m.,
          New York City time, on the earlier of (i) the New York Business
          Day immediately preceding the Expiration Date and (ii) the last
          New York Business Day prior to the effective date on which the
          Warrants are delisted from, or permanently suspended from trading
          on (within the meaning of the Securities Exchange Act of 1934 and
          the rules and regulations of the Securities and Exchange Commis-
          sion thereunder), the New York Stock Exchange and not accepted at
          the same time for listing on another United States national
          securities exchange (such New York Business Day being the
          "Delisting Date"), shall be deemed not to have been delivered and
          the related Notice of Exercise shall be void and of no effect;
          provided, however, that if the Company first receives notice of
          such delisting or suspension of the Warrants on the same day on
          which such Warrants are delisted or suspended, such day will be
          deemed the Delisting Date for purposes of the Warrant Agreement
          and this Warrant Certificate.  

                    If the Notice of Exercise is not rejected as provided
          in the Warrant Agreement, then the Warrant Agent or the Spot Rate
          Reference Agent, as the case may be, will determine the Cash
          Settlement Value of the exercised Warrants in accordance with the
          terms of the Warrant Agreement.  Any exercise of the Warrants
          will be irrevocable, except as provided in the immediately
          succeeding sentence and for the limited circumstances in which an
          exercise may be treated as contingent pursuant to the Limit
          Option, as provided in the Warrant Agreement.  Except in the case
          of Warrants subject to automatic exercise, if on any Valuation
          Date the Cash Settlement Value for any Warrants then exercised
          would be zero, then in such case, the exercise of such Warrants
          shall be void and of no effect and the Warrant Certificate
          evidencing such Warrants will be promptly returned by the Warrant
          Agent to the Registered Holder by first class mail at the
          Company's expense and such Warrantholder shall be permitted to
          re-exercise such Warrants prior to the Expiration Date or the


          Delisting Date, as the case may be.

                    Except in the case of Warrants subject to automatic
          exercise, payment shall be made available to each appropriate
          Registered Holder on the fifth New York Business Day following
          the Valuation Date for such Warrants in the form of a cashier's
          check or an official bank check, or (in the case of payments of
          at least $100,000) by wire transfer to a U.S. dollar bank account
          maintained by such Registered Holder in the United States (at
          such Registered Holder's election as specified in the Notice of

          Exercise), in an amount equal to the aggregate Cash Settlement
          Value of the exercised Warrants.

                    All Warrants for which the Warrant Agent has not
          received a Notice of Exercise in proper form at or prior to
          3:00 p.m., New York City time, on the earlier of (i) the New York
          Business Day preceding the Expiration Date and (ii) the Delisting
          Date, or for which the Warrant Agent has received a Notice of
          Exercise in proper form but with respect to which timely delivery
          of the relevant Warrant Certificate has not been made, will be
          deemed automatically exercised on such date without any
          requirement of a Notice of Exercise to the Warrant Agent.  The
          Valuation Date for such Warrants shall be the first New York
          Business Day following the Expiration Date or the Delisting Date,
          as the case may be.

                    Payment with respect to automatically exercised
          Warrants shall be made available to each appropriate Registered
          Holder in the form of a cashier's check or an official bank
          check, or (in the case of payments of at least $100,000) by wire
          transfer to a U.S. dollar account maintained by such Registered
          Holder in the United States (at such Registered Holder's
          election), on the fourth New York Business Day following the
          Valuation Date for automatically exercised Warrants, against
          receipt by the Warrant Agent at the Warrant Agent's Office from
          the Registered Holder of its Warrant Certificates.  Such payment
          shall be in the amount of the aggregate Cash Settlement Value in
          respect of the Warrants, evidenced by the Warrant Certificates,
          that were automatically exercised on the Expiration Date or the
          Delisting Date, as the case may be.

                    All exercises of Warrants (other than on the Expiration
          Date or the Delisting Date) shall be subject, at the Company's
          option, to the limitation that not more than 1,000,000 Warrants


          in total may be exercised on any Exercise Date and not more than
          250,000 Warrants may be exercised by or on behalf of any person
          or entity, either individually or in concert with any other
          person or entity, on any Exercise Date.  If any New York Business
          Day would otherwise, under the terms hereof, be the Exercise Date
          in respect of more than 1,000,000 Warrants, then upon the
          Company's exercising such option (by giving notice thereof to the
          Warrant Agent not later than 5:00 p.m., New York City time, on
          the New York Business Day immediately following such Exercise
          Date), 1,000,000 of such Warrants shall be deemed exercised on
          such Exercise Date (selected by the Warrant Agent on a pro rata
          basis, but if, as a result of such pro rata selection, any
          Registered Holders would be deemed to have exercised less than
          500 Warrants, then the Warrant Agent shall first select
          additional Warrants of such Registered Holders so that no such
          Registered Holder shall be deemed to have exercised less than
          500 Warrants), and the remainder of such Warrants (the "Remaining
          Warrants") shall be deemed exercised on the following New York
          Business Day (notwithstanding the minimum exercise requirement in
          the Warrant Agreement and subject to successive applications of

          
                                         A-6

          this paragraph); provided, however, that any Remaining Warrant in
          respect of which a Notice of Exercise was delivered on a given
          Notice Date shall be deemed exercised before any other Warrants
          in respect of which a Notice of Exercise was delivered on a later
          Notice Date.  If any individual Warrantholder attempts to
          exercise more than 250,000 Warrants on any New York Business Day,
          then at the Company's election (as notified to the Warrant Agent
          by giving notice thereof to the Warrant Agent not later than 5:00
          p.m., New York City time, on the New York Business Day
          immediately following such New York Business Day) 250,000 of such
          Warrants shall be deemed exercised on such New York Business Day
          and the remainder shall be deemed exercised on the following New
          York Business Day (subject to successive applications of this
          paragraph).  The date on which any Warrant is deemed exercised
          under the preceding sentences shall for all purposes of this
          Warrant Certificate be deemed to be the "Exercise Date" in
          respect of such Warrant.

                    Prior to due presentment for registration of transfer,
          the Company, the Warrant Agent, and any agent of the Company or
          the Warrant Agent, may deem and treat the registered owner hereof
          as the absolute owner of the Warrants evidenced hereby
          (notwithstanding any notation of ownership or other writing
          hereon) for any purpose whatsoever, and as the person entitled to
          exercise the rights represented by the Warrants evidenced hereby,


          and neither the Company nor the Warrant Agent, nor any agent of
          the Company or the Warrant Agent, shall be affected by any notice
          to the contrary.

                    The Warrant Agent shall, in accordance with the Warrant
          Agreement, from time to time register the transfer of this
          Warrant Certificate upon the records to be maintained by it for
          that purpose at the Warrant Agent's Office upon surrender hereof,
          duly endorsed, or accompanied by a written instrument or
          instruments of transfer in form satisfactory to the Warrant Agent
          and the Company, duly executed by the Registered Holder(s) hereof
          or by their duly appointed legal representative or duly
          authorized attorney, such signature to be guaranteed by a bank or
          trust company with a correspondent office in The City of New York
          or by a member of a national securities exchange.  Upon any such
          registration of transfer, a new Warrant Certificate shall be
          issued to the transferee(s).

                    As provided in the Warrant Agreement and subject to
          certain limitations, this Warrant Certificate may be exchanged
          for other Warrant Certificates, of like tenor and representing an
          equal number of Warrants, upon surrender to the Warrant Agent of
          this Warrant Certificate at the Warrant Agent's Office.

                    No service charge shall be made for any registration of
          transfer or exchange of this Warrant Certificate, but the Company
          may require payment of a sum sufficient to cover any tax or other
          governmental charge that may be imposed in connection with any
          registration of transfer or exchange of this Warrant Certificate,

          Agreement).

                    2.  Subject to paragraph 1, the undersigned (the
          "Owner") hereby irrevocably exercises __________ Warrants (the
          "Exercised Warrants") and delivers to you herewith a Warrant

                               PAINE WEBBER GROUP INC.
                            U.S. Dollar Increase Warrants
                                 on the Japanese Yen

                               Expiring April 30, 1996


                    This certifies that CEDE & Co., or registered assigns,
          is the registered holder of _____________ U.S. Dollar Increase
          Warrants on the Japanese Yen Expiring April 30, 1996 (the "War-
          rants").  Each Warrant entitles the beneficial owner thereof
          (each a "Warrantholder") to receive, subject to the conditions
          set forth herein and in the Warrant Agreement, from Paine Webber
          Group Inc. (the "Company") the cash settlement value in U.S.
          dollars (rounded down to the nearest cent) (the "Cash Settlement
          Value") which is the greater of (i) zero and (ii) the amount
          computed by subtracting from U.S. $100 an amount equal to the
          product of U.S. $100 times a fraction, the numerator of which is
          yen 83.25 per U.S. $1.00 and the denominator of which is the Spot
          Rate.  The "Spot Rate" on any Valuation Date will be determined
          by the Spot Rate Reference Agent and will equal (a) the noon
          buying rate per U.S. $1.00 in The City of New York on such
          Valuation Date for cable transfers in Japanese yen as certified
          for customs purposes by the Federal Reserve Bank of New York (the
          "Noon Buying Rate"), as reported on page 1FEE of The Reuter
          Monitor Money Rates Service (or such page as may replace that
          page), or (b) if the Noon Buying Rate does not appear on such
          page by 1:00 p.m., New York City time, on such Valuation Date,
          the Noon Buying Rate on such Valuation Date as otherwise
          announced by the Federal Reserve Bank of New York, or (c) if the
          Federal Reserve Bank of New York has not quoted such Noon Buying
          Rate by 1:30 p.m., New York City time, on such Valuation Date,
          the offered spot rate of Japanese yen per U.S. $1.00 on such
          Valuation Date, which offered spot rate shall be calculated by
          the Spot Rate Reference Agent by (1) obtaining at approximately
          1:30 p.m., New York City time, a quote for a transaction amount
          approximately equivalent to U.S. $100 times the aggregate number
          of Warrants which were properly exercised on the related Exercise
          Date from each of five leading market makers (other than the Spot
          Rate Reference Agent) in the foreign exchange markets for
          Japanese yen selected by the Spot Rate Reference Agent, (2)
          discarding the highest and lowest quotes obtained and (3)
          averaging the three remaining quotes to determine such offered
          spot rate.




          
<PAGE>


                    The Spot Rate used to determine the Cash Settlement
          Value on any Valuation Date will be rounded to the second decimal
          place (e.g., 84.00), rounding up if the next succeeding decimal
          place, without regard to rounding, is five or higher.  Any such
          Cash Settlement Value will be rounded downwards, if necessary, to
          the nearest cent.  In no event shall a Warrantholder be entitled
          to any interest on any Cash Settlement Value.

                    Subject to the terms of the Warrant Agreement, each
          Warrant may be irrevocably exercised, in whole but not in part,
          at or prior to 3:00 p.m., New York City time, on any New York
          Business Day from its date of issuance until 3:00 p.m., New York
          City time, on the earlier of (i) the New York Business Day
          immediately preceding April 30, 1996 (the "Expiration Date") and
          (ii) the Delisting Date (as defined herein), after which time the
          Warrants shall expire and all Warrants evidenced hereby shall be
          void.  The holder of Warrants evidenced by this Global Warrant
          Certificate may exercise them only upon delivery of such Warrant
          free to the Warrant Account and pursuant to an irrevocable Notice
          of Exercise to the Warrant Agent from a Participant acting on
          behalf of such Warrantholder.  Except in the event of automatic
          exercise of the Warrants, as set forth herein and in the Warrant
          Agreement, not fewer than 500 Warrants may be exercised by or on
          behalf of any one Warrantholder at any one time.

                    This Global Warrant Certificate shall not be valid
          unless countersigned by the Warrant Agent.

                    The Warrants evidenced by this Global Warrant
          Certificate are part of a duly authorized issue of Warrants
          issued by the Company pursuant to a Warrant Agreement, dated as
          of May 1, 1995 (the "Warrant Agreement"), among the Company,
          Citibank, N.A. (the "Warrant Agent") and PaineWebber Incorporated
          (the "Spot Rate Reference Agent"), and is subject to the terms
          and provisions contained in the Warrant Agreement, to all of
          which terms and provisions the Warrantholders, the entities
          through which such Warrantholders hold their beneficial interests
          in the Warrants and the registered holder of this Global Warrant
          Certificate consent by acceptance of this Global Warrant
          Certificate by the Depository and which Warrant Agreement is
          hereby incorporated by reference in and made a part of this
          Global Warrant Certificate.  A copy of the Warrant Agreement is
          on file at the Warrant Agent's Office, which is located at
          111 Wall Street, 5th Floor, New York, New York 10043. 

                    The Warrants constitute direct, unconditional and
          unsecured obligations of the Company and rank on a parity with
          the Company's other unsecured contractual obligations and with


          the Company's unsecured and unsubordinated debt.

                    Subject to the Warrant Agreement and this Global
          Warrant Certificate, and except in the event of exercise (whether
          automatic or by Notice of Exercise) on the Expiration Date or the
          Delisting Date, or in the case of a postponement due to there

          being exercised a number of Warrants in excess of the maximum
          permitted number on a given day, the valuation date (the
          "Valuation Date") for a Warrant shall be the first New York
          Business Day (as defined herein) next succeeding the New York
          Business Day (the "Exercise Date") on which the Warrant Agent has
          received (i) in the case of Warrants other than those held
          through the facilities of Centrale de Livraison de Valeurs
          Mobilieres S.A. ("CEDEL") or the Euroclear System ("Euroclear"),
          the Warrant, with the Notice of Exercise (or a Notice of Exercise
          in substantially identical form), duly completed and executed, at
          or prior to 3:00 p.m., New York City time (the "Notice Date");
          and if the Warrant Agent shall receive any such Warrant after
          3:00 p.m., New York City time, on such date, then such Warrant
          shall be deemed to have been received at or prior to 3:00 p.m.,
          New York City time, on the next succeeding New York Business Day
          (which shall be considered the Notice Date), and in such event
          the Valuation Date shall be the next New York Business Day
          following the New York Business Day on which the Warrant Agent is
          deemed to have received such Warrant together with the Notice of
          Exercise or (ii) in the case of Warrants held through the
          facilities of CEDEL or Euroclear, the Notice of Exercise (by
          facsimile transmission) at or prior to 3:00 p.m., New York City
          time; provided that the Warrant is received by the Warrant Agent
          by 3:00 p.m., New York City time, on the New York Business Day
          next succeeding the Exercise Date; and if the Warrant Agent shall
          receive such Notice of Exercise after 3:00 p.m., New York City
          time, on such date, then the Notice of Exercise shall be deemed
          to have been received at or prior to 3:00 p.m., New York City
          time, on the next succeeding New York Business Day (which shall
          be considered the Notice Date), and in such event the Valuation
          Date shall be the next New York Business Day following the
          New York Business Day on which the Warrant Agent is deemed to
          have received such Notice of Exercise; provided, however, that if
          the Warrant Agent receives the Warrant after 3:00 p.m., New York
          City time, on the Valuation Date, then the Exercise Date for such
          Warrant shall be the day on which such Warrant is received or, if
          such day is not a New York Business Day, the next succeeding
          New York Business Day, and the Valuation Date for such Warrant
          shall be the first New York Business Day following such Exercise


          Date; provided further, however, in the case of exercises by
          Euroclear participants, Euroclear must, by tested telex to the
          Warrant Agent by 9:00 a.m., New York City time, on the Valuation
          Date, confirm that the Warrants will be received by the Warrant
          Agent on such date, provided that if such telex communication is
          received after 9:00 a.m., New York City time, on the Valuation
          Date, the Company will be entitled to direct the Warrant Agent to
          reject the related Notice of Exercise or waive the requirement

          Expiration Date and (b) the last New York Business Day prior to
          the effective date on which the Warrants are delisted from, or

          the Securities and Exchange Commission thereunder), the New York
          Stock Exchange (the "NYSE") and not accepted at the same time for
          listing on another United States national securities exchange
          (such New York Business Day being the "Delisting Date") (or, in
          the case of Warrants held through the facilities of CEDEL or
          Euroclear, after 3:00 p.m., New York City time, on the first
          New York Business Day following such dates), shall be deemed not
          to have been delivered and the related Notice of Exercise shall
          be void and of no effect; provided, however, that if the Company
          first receives notice of the delisting or suspension of the
          Warrants on the same day on which such Warrants are delisted or
          suspended, such day will be deemed the Delisting Date for
          purposes of the Warrant Agreement and this Global Warrant
          Certificate.

                    All Warrants for which the Warrant Agent has not
          received a Notice of Exercise in proper form by 3:00 p.m., New
          York City time, on the earlier of (i) the New York Business Day
          preceding the Expiration Date and (ii) the Delisting Date, or for
          which the Warrant Agent has received a Notice of Exercise in
          proper form but with respect to which timely delivery of the
          related Warrant has not been made, will be deemed automatically
          exercised on such date without any requirement of a Notice of
          Exercise to the Warrant Agent.  The Valuation Date shall be the
          first New York Business Day following the Expiration Date or the
          Delisting Date, as the case may be.

                    All exercises of Warrants (other than on the Expiration
          Date or the Delisting Date) shall be subject, at the Company's
          option, to the limitation that not more than 1,000,000 Warrants


          in total may be exercised on any Exercise Date and not more than
          250,000 Warrants may be exercised by or on behalf of any person
          or entity, either individually or in concert with any other
          person or entity, on any Exercise Date.  If any New York Business
          Day would otherwise, under the terms hereof be the Exercise Date
          in respect of more than 1,000,000 Warrants, then upon the
          Company's exercising such option (by giving notice thereof to the
          Warrant Agent not later than 5:00 p.m., New York City time, on
          the Business Day immediately following such Exercise Date),
          1,000,000 of such Warrants shall be deemed exercised on such
          Exercise Date (selected by the Warrant Agent on a pro rata basis,
          but if, as a result of such pro rata selection, any Registered
          Holders would be deemed to have exercised less than 500 Warrants,
          then the Warrant Agent shall first select additional Warrants of
          such Registered Holders so that no such Registered Holder shall
          be deemed to have exercised less than 500 Warrants), and the
          remainder of such Warrants (the "Remaining Warrants") shall be
          deemed exercised on the following New York Business Day
          (notwithstanding the minimum exercise requirement in the Warrant
          Agreement and subject to successive applications of this
          paragraph); provided, however, that any Remaining Warrant in
          respect of which a Notice of Exercise was delivered on a given
          Notice Date shall be deemed exercised before any other Warrants
          in respect of which a Notice of Exercise was delivered on a later

          Notice Date.  If any individual Warrantholder attempts to
          exercise more than 250,000 Warrants on any New York Business Day,
          then at the Company's election (as notified to the Warrant Agent
          by giving notice thereof to the Warrant Agent not later than 5:00
          p.m., New York City time, on the New York Business Day following
          such New York Business Day) 250,000 of such Warrants shall be
          deemed exercised on such New York Business Day and the remainder
          shall be deemed exercised on the following New York Business Day
          (subject to successive applications of this paragraph).  The date
          on which any Warrant is deemed exercised under the preceding
          sentences shall for all purposes of this Global Warrant
          Certificate be deemed to be the "Exercise Date" in respect of
          such Warrant.

                    Prior to due presentment for registration of transfer,
          the Company, the Warrant Agent, and any agent of the Company or
          the Warrant Agent, may deem and treat the registered owner hereof
          as the absolute owner of the Warrants evidenced hereby
          (notwithstanding any notation of ownership or other writing
          hereon) for any purpose whatsoever, and as the person entitled to
          exercise the rights represented by the Warrants evidenced hereby,


          and neither the Company nor the Warrant Agent, nor any agent of
          the Company or the Warrant Agent, shall be affected by any notice
          to the contrary.

                    The Warrant Agent shall, in accordance with the Warrant
          Agreement, from time to time register the transfer of this Global
          Warrant Certificate in its records (which may be maintained
          electronically) to be maintained by it for that purpose at the
          Warrant Agent's Office upon surrender hereof, duly endorsed, or
          accompanied by a written instrument or instruments of transfer in
          form satisfactory to the Warrant Agent, duly executed by the
          registered holder hereof or by the duly appointed legal represen-
          tative or duly authorized attorney thereof, such signature to be
          guaranteed by a bank or trust company with a correspondent office
          in The City of New York or by a member of a national securities
          exchange.  Upon any such registration of transfer, a new Global
          Warrant Certificate shall be issued to the transferee.

                    Exercises of Warrants may be subject to the Limit
          Option as provided in the Warrant Agreement.

                    Capitalized terms included herein but not defined
          herein have the meanings assigned thereto in the Warrant
          Agreement.

          Date for the Tendered Warrants to be the New York Business Day

          Day), the Valuation Date of the Tendered Warrants shall be the

          Day, in each case subject to certain provisions of the Warrant
          Agreement.
