on the Transaction Date will be deemed to have been in effect
during the Four Quarter Period; and (3) notwithstanding clause
(1) above, interest on Indebtedness determined on a fluctuating
basis, to the extent such interest is covered by agreements
relating to Interest Swap Obligations, shall be

Notes in registered form, substantially in the form set forth
in Exhibit A (the "Global Note"), deposited with the Trustee,
as custodian for the Depository, duly executed by the Company
and authenticated by the Trustee as hereinafter provided.  The
aggregate principal amount of the Global Note may from time to
time be increased or decreased by adjustments made on the
records of the Trustee, as custodian for the Depository, as
hereinafter provided.

            Notes offered and sold in offshore transactions in
reliance on Regulation S shall be issued in the form of
permanent certificated Notes in registered form in
substantially the form set forth in Exhibit A (the "Offshore
Physical Notes").  Notes offered and sold in reliance on any
other exemption from registration under the Securities Act
other than as described in the preceding paragraph shall be
issued, and Notes offered and sold in reliance on Rule 144A may
be issued, in the form of permanent certificated Notes in
registered form, in substantially the form set forth in
Exhibit A (the "U.S. Physical Notes").  The Offshore Physical
Notes and the U.S. Physical Notes are sometimes collectively
herein referred to as the "Physical Notes."  Physical Notes
shall initially be registered in the name of the Depository or
the nominee of such Depository and be delivered to the Trustee
as custodian for such Depository.  Beneficial owners of
Physical Notes, however, may request registration of such
Physical Notes in their names or the names of their nominees.

            SECTION 2.02.  Execution and Authentication;
                           Aggregate Principal Amount.
                           -----------------------------

            Two Officers, or an Officer and an Assistant
Secretary, shall sign, or one Officer shall sign and one
Officer or an Assistant Secretary (each of whom shall, in each
case, have been duly authorized by all requisite corporate
actions) shall

 
                                      -35-

attest to, the Notes for the Company by manual or facsimile 
signature.  The Company's seal shall also be reproduced on 
the Notes. 

            If an Officer or Assistant Secretary whose signature
is on a Note was an Officer or Assistant Secretary at the time
of such execution but no longer holds that office or position
at the time the Trustee authenticates the Note, the Note shall
nevertheless be valid.

            A Note shall not be valid until an authorized
signatory of the Trustee manually signs the certificate of
authentication on the Note.  The signature shall be conclusive
evidence that the Note has been authenticated under this
Indenture.

            The Trustee shall authenticate (i) Initial Notes for
original issue in the aggregate principal amount not to exceed
$350,000,000, and (ii) Exchange Notes from time to time for
issue only in exchange for a like principal amount of Initial
Notes, in each case upon written orders of the Company in the
form of an Officers' Certificate.  The Officers' Certificate
shall specify the amount of Notes to be authenticated, the date
on which the Notes are to be authenticated and the aggregate
principal amount of Notes outstanding on the date of
authentication, whether the Notes are to be Initial Notes or
Exchange Notes, and shall further specify the amount of such
Notes to be issued as the Global Note, Offshore Physical Notes
or U.S. Physical Notes.  The aggregate principal amount of
Notes outstanding at any time may not exceed $350,000,000,
except as provided in Section 2.07.

            The Trustee shall not be required to authenticate
Notes if the issuance of such Notes pursuant to this Indenture
will affect the Trustee's own rights, duties or immunities
under the Notes and this Indenture in a manner which is not
reasonably acceptable to the Trustee.

            The Trustee may appoint an authenticating agent (the
"Authenticating Agent") reasonably acceptable to the Company to
authenticate Notes.  Unless otherwise provided in the
appointment, an Authenticating Agent may authenticate Notes
whenever the Trustee may do so.  Each reference in this
Indenture to authentication by the Trustee includes
authentication by such Authenticating Agent.  An Authenticating
Agent has the same rights as an Agent to deal with the Company
and Affiliates of the Company.

 
                                      -36-

            The Notes shall be issuable in fully registered form
only, without coupons, in denominations of $1,000 and any
integral multiple thereof.

            SECTION 2.03.  Registrar and Paying Agent.
                           --------------------------

            The Company shall maintain an office or agency (which
shall be located in the Borough of Manhattan in the City of New
York, State of New York) where (a) Notes may be presented or
surrendered for registration of transfer or for exchange
("Registrar"), (b) Notes may be presented or surrendered for
payment ("Paying Agent") and (c) notices and demands to or upon
the Company in respect of the Notes and this Indenture may be
served.  The Registrar shall keep a register of the Notes and
of their transfer and exchange.  The Company, upon prior
written notice to the Trustee, may have one or more
co-Registrars and one or more additional paying agents
reasonably acceptable to the Trustee.  The term "Paying Agent"
includes any additional Paying Agent.  Neither the Company nor
any Affiliate of the Company may act as Paying Agent.

            The Company shall enter into an appropriate agency
agreement with any Agent not a party to this Indenture, which
agreement shall incorporate the provisions of the TIA and
implement the provisions of this Indenture that relate to such
Agent.  The Company shall notify the Trustee, in advance, of
the name and address of any such Agent.  If the Company fails
to maintain a Registrar or Paying Agent, or fails to give the
foregoing notice, the Trustee shall act as such.

            The Company initially appoints the Trustee as
Registrar, Paying Agent and agent for service of demands and
notices in connection with the Notes, until such time as the
Trustee has resigned or a successor has been appointed.  The
Paying Agent or Registrar may resign upon 30 days notice to the
Company.

            SECTION 2.04.  Paying Agent To Hold Assets in Trust.
                           ------------------------------------

            The Company shall require each Paying Agent other
than the Trustee to agree in writing that each Paying Agent
shall hold in trust for the benefit of the Holders or the
Trustee all assets held by the Paying Agent for the payment of
principal of, or interest on, the Notes (whether such assets
have been distributed to it by the Company or any other obligor
on the Notes), and the Company and the Paying Agent shall
notify the Trustee of any Default by the Company (or any other

 
                                      -37-

obligor on the Notes) in making any such payment.  The Company
at any time may require a Paying Agent to distribute all assets
held by it to the Trustee and account for any assets disbursed
and the Trustee may at any time during the continuance of any
payment Default, upon written request to a Paying Agent,
require such Paying Agent to distribute all assets held by it
to the Trustee and to account for any assets distributed.  Upon
distribution to the Trustee of all assets that shall have been
delivered by the Company to the Paying Agent, the Paying Agent
shall have no further liability for such assets.

            SECTION 2.05.  Noteholder Lists.
                           ----------------

            The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of
the names and addresses of the Holders.  If the Trustee is not
the Registrar, the Company shall furnish or cause the Registrar
to furnish to the Trustee before each Record Date and at such
other times as the Trustee may request in writing a list as of
such date and in such form as the Trustee may reasonably
require of the names and addresses of the Holders, which list
may be conclusively relied upon by the Trustee.

            SECTION 2.06.  Transfer and Exchange.
                           ---------------------

            Subject to the provisions of Sections 2.16 and 2.17,
when Notes are presented to the Registrar or a co-Registrar
with a request to register the transfer of such Notes or to
exchange such Notes for an equal principal amount of Notes of
other authorized denominations, the Registrar or co-Registrar
shall register the transfer or make the exchange as requested
if its requirements for such transaction are met; provided,
                                                  --------
however, that the Notes presented or surrendered for
- -------
registration of transfer or exchange shall be duly endorsed or
accompanied by a written instrument of transfer in form
satisfactory to the Company and the Registrar or co-Registrar,
duly executed by the Holder thereof or his attorney duly
authorized in writing.  To permit registrations of transfer and
exchanges, the Company shall execute and the Trustee shall
authenticate Notes at the Registrar's or co-Registrar's
request.  No service charge shall be made for any registration
of transfer or exchange, but the Company may require payment of
a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith (other than
any such transfer taxes or similar governmental charge payable
upon exchanges or transfers pursuant to Sections 2.10, 3.06,
4.15, 4.16 or 9.06, 

 
                                      -38-

in which event the Company shall be responsible for the payment 
of such taxes).

            The Registrar or co-Registrar shall not be required
to register the transfer of or exchange of any Note (i) during
a period beginning at the opening of business 15 days before
the mailing of a notice of redemption of Notes and ending at
the close of business on the day of such mailing and
(ii) selected for redemption in whole or in part pursuant to
Article Three, except the unredeemed portion of any Note being
redeemed in part.

            Any Holder of the Global Note shall, by acceptance of
such Global Note, agree that transfers of beneficial interests
in such Global Notes may be effected only through a book entry
system maintained by the Holder of such Global Note (or its
agent), and that ownership of a beneficial interest in the Note
shall be required to be reflected in a book entry.

            SECTION 2.07.  Replacement Notes.
                           -----------------

            If a mutilated Note is surrendered to the Trustee or
if the Holder of a Note claims that the Note has been lost,
destroyed or wrongfully taken, the Company shall issue and the
Trustee shall authenticate a replacement Note if the Trustee's
requirements are met.  If required by the Trustee or the
Company, such Holder must provide an affidavit of lost
certificate and an indemnity bond or other indemnity,
sufficient in the judgment of both the Company and the Trustee,
to protect the Company, the Trustee or any Agent from any loss
which any of them may suffer if a Note is replaced.  The
Company may charge such Holder for its reasonable, out-of-
pocket expenses in replacing a Note, including reasonable fees
and expenses of counsel.  Every replacement Note shall
constitute an additional obligation of the Company.

            SECTION 2.08.  Outstanding Notes.
                           -----------------

            Notes outstanding at any time are all the Notes that
have been authenticated by the Trustee except those cancelled
by it, those delivered to it for cancellation and those
described in this Section as not outstanding.  Subject to the
provisions of Section 2.09, a Note does not cease to be
outstanding because the Company or any of its Affiliates holds
the Note.

 
                                      -39-

            If a Note is replaced pursuant to Section 2.07 (other
than a mutilated Note surrendered for replacement), it ceases
to be outstanding unless the Trustee receives an Opinion of
Counsel that the replaced Note is held by a bona fide
                                            ---- ----
purchaser.  A mutilated Note ceases to be outstanding upon
surrender of such Note and replacement thereof pursuant to
Section 2.07.

            If on a Redemption Date or the Maturity Date the
Paying Agent holds U.S. Legal Tender or U.S. Government
Obligations sufficient to pay all of the principal and interest
due on the Notes payable on that date and is not prohibited
from paying such money to the Holders thereof pursuant to the
terms of this Indenture, then on and after that date such Notes
cease to be outstanding and interest on them ceases to accrue.

            SECTION 2.09.  Treasury Notes.
                           --------------

            In determining whether the Holders of the required
principal amount of Notes have concurred in any direction,
waiver, consent or notice, Notes owned by the Company or any of
its Affiliates shall be considered as though they are not
outstanding, except that for the purposes of determining
whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes which a Trust Officer
of the Trustee actually knows are so owned shall be so
considered.  The Company shall notify the Trustee, in writing,
when it or any of its Affiliates repurchases or otherwise
acquires Notes, of the aggregate principal amount of such Notes
so repurchased or otherwise acquired.

            SECTION 2.10.  Temporary Notes.
                           ---------------

            Until definitive Notes are ready for delivery, the
Company may prepare and the Trustee shall authenticate
temporary Notes upon receipt of a written order of the Company
in the form of an Officers' Certificate.  The Officers'
Certificate shall specify the amount of temporary Notes to be
authenticated and the date on which the temporary Notes are to
be authenticated.  Temporary Notes shall be substantially in
the form of definitive Notes but may have variations that the
Company considers appropriate for temporary Notes.  Without
unreasonable delay, the Company shall prepare and the Trustee
shall authenticate upon receipt of a written order of the
Company pursuant to Section 2.02 definitive Notes in exchange
for temporary Notes.

 
                                      -40-

            SECTION 2.11.  Cancellation.
                           ------------

            The Company at any time may deliver Notes to the
Trustee for cancellation.  The Registrar and the Paying Agent
shall forward to the Trustee any Notes surrendered to them for
transfer, exchange or payment.  The Trustee, or at the
direction of the Trustee, the Registrar or the Paying Agent,
and no one else, shall cancel and, at the written direction of
the Company, shall dispose of all Notes surrendered for
transfer, exchange, payment or cancellation.  Subject to
Section 2.07, the Company may not issue new Notes to replace
Notes that it has paid or delivered to the Trustee for
cancellation.  If the Company shall acquire any of the Notes,
such acquisition shall not operate as a redemption or
satisfaction of the Indebtedness represented by such Notes
unless and until the same are surrendered to the Trustee for
cancellation pursuant to this Section 2.11.

            SECTION 2.12.  Defaulted Interest.
                           ------------------

            If the Company defaults in a payment of interest on
the Notes, it shall pay the defaulted interest, plus (to the
extent lawful) any interest payable on the defaulted interest
to the Persons who are Holders on a subsequent special record
date, which date shall be the fifteenth day next preceding the
date fixed by the Company for the payment of defaulted interest
or the next succeeding Business Day if such date is not a
Business Day.  At least 15 days before the subsequent special
record date, the Company shall mail to each Holder, as of a
recent date selected by the Company, with a copy to the
Trustee, a notice that states the subsequent special record
date, the payment date and the amount of defaulted interest,
and interest payable on such defaulted interest, if any, to be
paid.

            SECTION 2.13.  CUSIP Number.
                           ------------

            The Company in issuing the Notes may use a "CUSIP"
number, and if so, the Trustee shall use the CUSIP number in
notices of redemption or exchange as a convenience to Holders;
provided that no representation is hereby deemed to be made by
- --------
the Trustee as to the correctness or accuracy of the CUSIP
number printed in the notice or on the Notes, and that reliance
may be placed only on the other identification numbers printed
on the Notes.  The Company shall promptly notify the Trustee of
any change in the CUSIP number.

 
                                      -41-

            SECTION 2.14.  Deposit of Moneys.
                           -----------------

            Prior to 11:00 a.m. New York City time on each
Interest Payment Date and on the Maturity Date, the Company
shall have deposited with the Paying Agent in immediately
available funds money sufficient to make cash payments, if any,
due on such Interest Payment Date or Maturity Date, as the case
may be, in a timely manner which permits the Paying Agent to
remit payment to the Holders on such Interest Payment Date or
Maturity Date, as the case may be.

            SECTION 2.15.  Restrictive Legends.
                           -------------------

            Each Global Note and Physical Note that constitutes a
Restricted Security shall bear the following legend (the
"Private Placement Legend") on the face thereof until May 7,
1999, unless otherwise agreed by the Company and the Holder
thereof:

      THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE
      U.S. SECURITIES ACT OF 1933, AS AMENDED (THE
      "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE
      OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR
      FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS EXCEPT
      AS SET FORTH BELOW.  BY ITS ACQUISITION HEREOF,
      THE HOLDER (1) REPRESENTS THAT (A) IT IS A
      "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN
      RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS
      AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED
      IN RULE 501(a)(1), (2), (3) OR (7) UNDER THE
      SECURITIES ACT) (AN "ACCREDITED INVESTOR") OR (C)
      IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS
      SECURITY IN AN OFFSHORE TRANSACTION, (2) AGREES
      THAT IT WILL NOT WITHIN THREE YEARS AFTER THE
      ORIGINAL ISSUANCE OF THIS SECURITY RESELL OR
      OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE
      ISSUER OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE
      UNITED STATES TO A QUALIFIED INSTITUTIONAL BUYER
      IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES
      ACT, (C) INSIDE THE UNITED STATES TO AN
      INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO
      SUCH TRANSFER, FURNISHES (OR HAS FURNISHED ON ITS
      BEHALF BY A U.S. BROKER-DEALER) TO THE TRUSTEE A
      SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS
      AND AGREEMENTS RELATING TO THE RESTRICTIONS ON
      TRANSFER OF THIS SECURITY (THE FORM OF WHICH
      LETTER CAN BE OBTAINED FROM THE TRUSTEE OR
      REGISTRAR), (D) OUTSIDE THE UNITED STATES IN AN
      OFFSHORE TRANSACTION IN 

 
                                      -42-

      COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE 
      SECURITIES ACT, (E) PURSUANT TO THE EXEMPTION FROM 
      REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES 
      ACT (IF AVAILABLE) OR (F) PURSUANT TO AN EFFECTIVE
      REGISTRATION STATEMENT UNDER THE SECURITIES ACT
      AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON
      TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE
      SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN
      CONNECTION WITH ANY TRANSFER OF THIS SECURITY
      WITHIN THREE YEARS AFTER THE ORIGINAL ISSUANCE OF
      THE SECURITY, IF THE PROPOSED TRANSFEREE IS AN
      INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER
      MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE
      TRUSTEE AND THE ISSUER SUCH CERTIFICATIONS, LEGAL
      OPINIONS OR OTHER INFORMATION AS EITHER OF THEM
      MAY REASONABLY REQUIRE TO CONFIRM THAT SUCH
      TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION
      FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
      REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.
      AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION,"
      "UNITED STATES" AND "U.S. PERSON" HAVE THE
      MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE
      SECURITIES ACT.

            Each Global Note shall also bear the following legend
on the face thereof:

      UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN
      PART FOR SECURITIES IN DEFINITIVE FORM, THIS
      SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE
      BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY,
      OR BY ANY SUCH NOMINEE OF THE DEPOSITARY, OR BY
      THE DEPOSITARY OR NOMINEE OF SUCH SUCCESSOR
      DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR
      DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR
      DEPOSITARY. UNLESS THIS CERTIFICATE IS PRESENTED
      BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY
      TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO
      THE ISSUER OR ITS AGENT FOR REGISTRATION OF
      TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE
      ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR
      SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED
      REPRESENTATIVE OF DTC (AND ANY PAYMENT HEREON IS
      MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS
      REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC),
      ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE
      OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
      INASMUCH AS THE 

 
                                      -43-

      REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST 
      HEREIN. TRANSFERS OF THIS GLOBAL SECURITY SHALL BE 
      LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO
      NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF
      OR SUCH SUCCESSOR'S NOMINEE AND TRANSFERS OF
      PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED
      TO TRANSFERS MADE IN ACCORDANCE WITH THE
      RESTRICTIONS SET FORTH IN SECTION 2.17 OF THE
      INDENTURE.

            SECTION 2.16.  Book-Entry Provisions
                           for Global Security. 
                           ---------------------

            (a)   The Global Note initially shall (i) be
registered in the name of the Depository or the nominee of such
Depository, (ii) be delivered to the Trustee as custodian for
such Depository and (iii) bear legends as set forth in Sec-
tion 2.15.

            Members of, or participants in, the Depository
("Agent Members") shall have no rights under this Indenture
with respect to any Global Note held on their behalf by the
Depository, or the Trustee as its custodian, or under the
Global Note, and the Depository may be treated by the Company,
the Trustee and any agent of the Company or the Trustee as the
absolute owner of the Global Note for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee
from giving effect to any written certification, proxy or other
authorization furnished by the Depository or impair, as between
the Depository and its Agent Members, the operation of
customary practices governing the exercise of the rights of a
holder of any Note.

            (b)   Transfers of the Global Note shall be limited to
transfers in whole, but not in part, to the Depository, its
successors or their respective nominees.  Interests of
beneficial owners in the Global Note may be transferred or
exchanged for Physical Notes in accordance with the rules and
procedures of the Depository and the provisions of Section
2.17.  In addition, Physical Notes shall be transferred to all
beneficial owners in exchange for their beneficial interests in
the Global Note if (i) the Depository notifies the Company that
it is unwilling or unable to continue as Depository for the
Global Note and a successor depositary is not appointed by the
Company within 90 days of such notice or (ii) an Event of
Default has

 
                                      -44-

occurred and is continuing and the Registrar has received a 
written request from the Depository to issue Physical Notes.

            (c)   In connection with any transfer or exchange of a
portion of the beneficial interest in the Global Note to
beneficial owners pursuant to paragraph (b), the Registrar
shall (if one or more Physical Notes are to be issued) reflect
on its books and records the date and a decrease in the
principal amount of the Global Note in an amount equal to the
principal amount of the beneficial interest in the Global Note
to be transferred, and the Company shall execute, and the
Trustee shall authenticate and deliver, one or more Physical
Notes of like tenor and amount.

            (d)   In connection with the transfer of the entire
Global Note to beneficial owners pursuant to paragraph (b), the
Global Note shall be deemed to be surrendered to the Trustee
for cancellation, and the Company shall execute, and the
Trustee shall authenticate and deliver, to each beneficial
owner identified by the Depository in exchange for its
beneficial interest in the Global Note, an equal aggregate
principal amount of Physical Notes of authorized denominations.

            (e)   Any Physical Note constituting a Restricted
Security delivered in exchange for an interest in the Global
Note pursuant to paragraph (b) or (c) shall, except as
otherwise provided by paragraphs (a)(i)(x) and (c) of Section
2.17, bear the legend regarding transfer restrictions
applicable to the Physical Notes set forth in Section 2.15.

            (f)   The Holder of the Global Note may grant proxies
and otherwise authorize any person, including Agent Members and
persons that may hold interests through Agent Members, to take
any action which a Holder is entitled to take under this
Indenture or the Notes.

            SECTION 2.17.  Special Transfer Provisions.
                           ---------------------------

            (a)   Transfers to Non-QIB Institutional Accredited
                  ---------------------------------------------
Investors and Non-U.S. Persons.  The following provisions shall
- ------------------------------
apply with respect to the registration of any proposed transfer
of a Note constituting a Restricted Security to any
Institutional Accredited Investor which is not a QIB or to any
Non-U.S. Person:

            (i)  the Registrar shall register the transfer of any
      Note constituting a Restricted Security, whether or not

 
                                      -45-

      such Note bears the Private Placement Legend, if (x) the
      requested transfer is after May 7, 1999 or (y) (1) in the
      case of a transfer to an Institutional Accredited Investor
      which is not a QIB (excluding Non-U.S. Persons), the
      proposed transferee has delivered to the Registrar a
      certificate substantially in the form of Exhibit C hereto
      or (2) in the case of a transfer to a Non-U.S. Person, the
      proposed transferor has delivered to the Registrar a
      certificate substantially in the form of Exhibit D hereto;
      and

           (ii)  if the proposed transferor is an Agent Member
      holding a beneficial interest in the Global Note, upon
      receipt by the Registrar of (x) the certificate, if any,
      required by paragraph (i) above and (y) instructions given
      in accordance with the Depository's and the Registrar's
      procedures,

whereupon (a) the Registrar shall reflect on its books and
records the date and (if the transfer does not involve a

principal amount of the Global Note in an amount equal to the
principal amount of the beneficial interest in the Global Note
to be transferred, and (b) the Company shall execute and the
Trustee shall authenticate and deliver one or more Physical
Notes of like tenor and amount.

            (b)   Transfers to QIBs.  The following provisions
                  -----------------
shall apply with respect to the registration of any proposed
transfer of a Note constituting a Restricted Security to a QIB
(excluding transfers to Non-U.S. Persons):

            (i)  the Registrar shall register the transfer if
      such transfer is being made by a proposed transferor who
      has checked the box provided for on the form of Note
      stating, or has otherwise advised the Company and the
      Registrar in writing, that the sale has been made in
      compliance with the provisions of Rule 144A to a
      transferee who has signed the certification provided for
      on the form of Note stating, or has otherwise advised the
      Company and the Registrar in writing, that it is
      purchasing the Note for its own account or an account with
      respect to which it exercises sole investment discretion
      and that it and any such account is a QIB within the
      meaning of Rule 144A, and is aware that the sale to it is
      being made in reliance on Rule 144A and acknowledges that
      it has received such information regarding the Company as
      it has requested 

 
                                      -46-

      pursuant to Rule 144A or has determined not to request 
      such information and that it is aware that the transferor 
      is relying upon its foregoing representations in order to 
      claim the exemption from registration provided by Rule 
      144A; and

           (ii)  if the proposed transferee is an Agent Member,
      and the Notes to be transferred consist of Physical Notes
      which after transfer are to be evidenced by an interest in
      the Global Note, upon receipt by the Registrar of
      instructions given in accordance with the Depository's and
      the Registrar's procedures, the Registrar shall reflect on
      its books and records the date and an increase in the
      principal amount of the Global Note in an amount equal to
      the principal amount of the Physical Notes to be
      transferred, and the Trustee shall cancel the Physical
      Notes so transferred.

            (c)   Private Placement Legend.  Upon the transfer,
                  ------------------------
exchange or replacement of Notes not bearing the Private
Placement Legend, the Registrar shall deliver Notes that do not
bear the Private Placement Legend.  Upon the transfer, exchange
or replacement of Notes bearing the Private Placement Legend,
the Registrar shall deliver only Notes that bear the Private
Placement Legend unless (i) the circumstance contemplated by
paragraph (a)(i)(x) of this Section 2.17 exist or (ii) there is
delivered to the Registrar an Opinion of Counsel reasonably
satisfactory to the Company and the Trustee to the effect that
neither such legend nor the related restrictions on transfer
are required in order to maintain compliance with the
provisions of the Securities Act.

            (d)   General.  By its acceptance of any Note bearing
                  -------
the Private Placement Legend, each Holder of such a Note
acknowledges the restrictions on transfer of such Note set
forth in this Indenture and in the Private Placement Legend and
agrees that it will transfer such Note only as provided in this
Indenture.

            The Registrar shall retain copies of all letters,
notices and other written communications received pursuant to
Section 2.16 or this Section 2.17.  The Company shall have the
right to inspect and make copies of all such letters, notices
or other written communications at any reasonable time upon the
giving of reasonable written notice to the Registrar.

                                REDEMPTION

            SECTION 3.01.  Notices to Trustee.
                           ------------------

            If the Company elects to redeem Notes pursuant to
Paragraph 6 of the Notes, it shall notify the Trustee and the
Paying Agent in writing of the Redemption Date and the
principal amount of the Notes to be redeemed.  

            The Company shall give each notice provided for in
this Section 3.01 at least 60 days before the Redemption Date
(unless a shorter notice period shall be satisfactory to the
Trustee, as evidenced in a writing signed on behalf of the
Trustee), together with an Officers' Certificate stating that
such redemption shall comply with the conditions contained
herein and in the Notes.

            SECTION 3.02.  Selection of Notes To Be Redeemed.
                           ---------------------------------

            If fewer than all of the Notes are to be redeemed,
the Trustee shall select the Notes to be redeemed on a pro rata
                                                       --- ----
basis, by lot or in such other fair and reasonable manner
chosen at the discretion of the Trustee; provided, however,
                                         --------  -------
that if a partial redemption is made with the proceeds of an
Equity Offering, selection of the Notes or portion thereof for
redemption shall be made by the Trustee only on a pro rata
                                                  --- ----
basis, unless such method is otherwise prohibited.  The Trustee
shall make the selection from the Notes outstanding and not
previously called for redemption and shall promptly notify the
Company in writing of the Notes selected for redemption and, in
the case of any Note selected for partial redemption, the
principal amount thereof to be redeemed.  Notes in
denominations of $1,000 may be redeemed only in whole.  The
Trustee may select for redemption portions (equal to $1,000 or
any integral multiple thereof) of the principal of Notes that
have denominations larger than $1,000.  Provisions of this
Indenture that apply to Notes called for redemption also apply
to portions of Notes called for redemption.

            SECTION 3.03.  Notice of Redemption.
                           --------------------

            At least 30 days but not more than 60 days before a
Redemption Date, the Company shall mail or cause to be mailed a
notice of redemption by first class mail, postage prepaid, to
each Holder whose Notes are to be redeemed, with a copy to the

 
                                      -48-

Trustee and any Paying Agent.  At the Company's written
request, the Trustee shall give the notice of redemption in the
Company's name and at the Company's expense.  

            Each notice for redemption shall identify the Notes
to be redeemed and shall state:

            (1)   the Redemption Date;

            (2)   the Redemption Price and the amount of accrued
      interest, if any, to be paid;

            (3)   the name and address of the Paying Agent;

            (4)   the subparagraph of the Notes pursuant to which
      such redemption is being made;

            (5)   that Notes called for redemption must be
      surrendered to the Paying Agent to collect the Redemption
      Price plus accrued interest, if any;

            (6)   that, unless the Company defaults in making the
      redemption payment, interest on Notes called for
      redemption ceases to accrue on and after the Redemption
      Date, and the only remaining right of the Holders of such
      Notes is to receive payment of the Redemption Price plus
      accrued interest, if any, upon surrender to the Paying
      Agent of the Notes redeemed;

            (7)   if any Note is being redeemed in part, the
      portion of the principal amount of such Note to be
      redeemed and that, after the Redemption Date, and upon
      surrender of such Note, a new Note or Notes in the
      aggregate principal amount equal to the unredeemed portion
      thereof will be issued; and

            (8)   if fewer than all the Notes are to be redeemed,
      the identification of the particular Notes (or portion
      thereof) to be redeemed, as well as the aggregate
      principal amount of Notes to be redeemed and the aggregate
      principal amount of Notes to be outstanding after such
      partial redemption.

            SECTION 3.04.  Effect of Notice of Redemption.
                           ------------------------------

            Once notice of redemption is mailed in accordance
with Section 3.03, Notes called for redemption become due and

 
                                      -49-

payable on the Redemption Date and at the Redemption Price plus
accrued interest, if any.  Upon surrender to the Trustee or
Paying Agent, such Notes called for redemption shall be paid at
the Redemption Price (which shall include accrued interest
thereon to the Redemption Date), but installments of interest,
the maturity of which is on or prior to the Redemption Date,
shall be payable to Holders of record at the close of business
on the relevant record dates referred to in the Notes.

            SECTION 3.05.  Deposit of Redemption Price.
                           ---------------------------

            On or before the Redemption Date, the Company shall
deposit with the Paying Agent U.S. Legal Tender sufficient to
pay the Redemption Price plus accrued interest, if any, of all
Notes to be redeemed on that date.  The Paying Agent shall
promptly return to the Company any U.S. Legal Tender so
deposited which is not required for that purpose, except with
respect to monies owed as obligations to the Trustee pursuant
to Article Seven.

            If the Company complies with the preceding paragraph,
then, unless the Company defaults in the payment of such
Redemption Price plus accrued interest, if any, interest on the
Notes to be redeemed will cease to accrue on and after the
applicable Redemption Date, whether or not such Notes are
presented for payment.

            SECTION 3.06.  Notes Redeemed in Part.
                           ----------------------

            Upon surrender of a Note that is to be redeemed in
part, the Company shall execute and the Trustee shall
authenticate for the Holder a new Note or Notes equal in
principal amount to the unredeemed portion of the Note
surrendered.


                               ARTICLE FOUR

            The Company shall pay the principal of and interest
on the Notes on the dates and in the manner provided in the
Notes and in this Indenture.  An installment of principal of or
interest on the Notes shall be considered paid on the date it
is due if the Trustee or Paying Agent (other than the Company
or an Affiliate of the Company) holds on that date U.S. Legal

 
                                      -50-

Tender designated for and sufficient to pay the installment in
full and is not prohibited from paying such money to the
Holders pursuant to the terms of this Indenture.

            The Company shall pay, to the extent such payments
are lawful, interest on overdue principal and on overdue
installments of interest (without regard to any applicable
grace periods) from time to time on demand at the rate borne by
the Notes plus 2% per annum.  Interest will be computed on the
basis of a 360-day year comprised of twelve 30-day months.

            Notwithstanding anything to the contrary contained in
this Indenture, the Company may, to the extent it is required
to do so by law, deduct or withhold income or other similar
taxes imposed by the United States of America from principal or
interest payments hereunder.

            SECTION 4.02.  Maintenance of Office or Agency.
                           -------------------------------

        The Company shall maintain the office or agency
required under Section 2.03.  The Company shall give prior
written notice to the Trustee of the location, and any change
in the location, of such office or agency.  If at any time the
Company shall fail to maintain any such required office or
agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands
may be made or served at the address of the Trustee set forth
in Section 11.02.

            SECTION 4.03.  Corporate Existence.
                           -------------------

            Except as otherwise permitted by Article Five and
Section 4.16, the Company shall do or cause to be done, at its
own cost and expense, all things necessary to preserve and keep
in full force and effect its corporate existence and the
corporate existence of each of its Restricted Subsidiaries in
accordance with the respective organizational documents of each
such Restricted Subsidiary and the material rights (charter and
statutory) and franchises of the Company and each such
Restricted Subsidiary; provided, however, that the Company
                       --------  -------
shall not be required to preserve, with respect to itself, any
material right or franchise and, with respect to any of its
Restricted Subsidiaries, any such existence, material right or
franchise, if the Board of Directors of the Company shall
determine in good faith that the preservation thereof is no
longer desirable in the conduct of the business of the Company
and the Restricted Subsidiaries, taken as a whole.

 
                                      -51-

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

            The Company shall pay or discharge or cause to be
paid or discharged, before the same shall become delinquent,
(i) all material taxes, assessments and governmental charges
(including withholding taxes and any penalties, interest and
additions to taxes) levied or imposed upon it or any of its
Subsidiaries or properties of it or any of its Subsidiaries and
(ii) all lawful claims for labor, materials and supplies that,
if unpaid, might by law become a Lien upon the property of it
or any of its Subsidiaries; provided, however, that the Company
                            --------  -------
shall not be required to pay or discharge or cause to be paid
or discharged any such tax, assessment, charge or claim whose
amount, applicability or validity is being contested in good
faith by appropriate proceedings properly instituted and
diligently conducted for which adequate reserves, to the extent
required under GAAP, have been taken.

            SECTION 4.05.  Maintenance of Properties
                           and Insurance.

            (a)   The Company shall, and shall cause each of its
Restricted Subsidiaries to, maintain its material properties in
good working order and condition (subject to ordinary wear and
tear) and make all necessary repairs, renewals, replacements,
additions, betterments and improvements thereto and actively
conduct and carry on its business; provided, however, that
                                   --------- ------- 
nothing in this Section 4.05 shall prevent the Company or any
of its Restricted Subsidiaries from discontinuing the operation
and maintenance of any of its properties, if such
discontinuance is, in the good faith judgment of the Board of
Directors of the Company or the Restricted Subsidiary, as the
case may be, desirable in the conduct of their respective
businesses and is not disadvantageous in any material respect
to the Holders.

            (b)   The Company shall provide or cause to be
provided, for itself and each of its Restricted Subsidiaries,
insurance (including appropriate self-insurance) against loss
or damage of the kinds that, in the good faith judgment of the

for the conduct of the business of the Company and such
Restricted Subsidiaries in a prudent manner, with reputable
insurers or with the government of the United States of America
or an agency or instrumentality thereof, in such amounts, with
such deductibles, and by such methods as shall be customary, in
the good faith judgment of the Board of Directors of the
Company, for companies similarly situated in the industry.

covenant and no Default or Event of Default occurred during
such year and at the date of such certificate there is no

pursuant to Section 4.08 shall be accompanied by a written
report of the Company's independent accountants (who shall be a
firm of established national reputation) that in conducting
their audit of such financial statements nothing has come to
their attention that would lead them to believe that the
Company has violated any provisions of Article Four, Five or

matters or, if any such violation has occurred, specifying the
nature and period of existence thereof, it being understood
that such accountants shall not be liable directly or

Directors of the Company or any such Restricted Subsidiary
party to such Affiliate Transaction shall have received an

restrictions apply only to such Securitization Entity; (10) any
agreement or instrument governing Indebtedness (whether or not
outstanding) of foreign Restricted Subsidiaries of the Company
incurred in reliance on clause (iii) of the definition of
Permitted Indebtedness; (11) other Indebtedness permitted to be
incurred subsequent to the Issue Date pursuant to Section 4.12;
provided that any such restrictions are ordinary and customary

provided that such amendments, modifications, restatements,
renewals increases, supplements, refundings, replacements or

dividend and other payment restrictions than those contained in
the dividend or other payment restrictions prior to such
amendment, modification, restatement, renewal, increase,
supplement, refunding, replacement or refinancing.

            SECTION 4.14.  Prohibition on Incurrence of

      accrued interest) and the purchase date (which shall be no
      earlier than 30 days nor later than 45 days from the date
      such notice is mailed, other than as may be required by
      law) (the "Change of Control Payment Date"); provided that
                                                   --------

      Holder to Elect Purchase" on the reverse of the Note
      completed, to the Paying Agent at the address specified in
      the notice prior to the close of business on the third
      Business Day prior to the Change of Control Payment Date;

            (6)   that Holders will be entitled to withdraw their
      election if the Paying Agent receives, not later than five
      Business Days prior to the Change of Control Payment Date,
      a telegram, telex, facsimile transmission or letter
      setting forth the name of the Holder, the principal amount
      of the Notes the Holder delivered for purchase and a
      statement that such Holder is withdrawing his election to
      have such Notes purchased;

            (7)   that Holders whose Notes are purchased only in
      part will be issued new Notes in a principal amount equal
      to the unpurchased portion of the Notes surrendered;

 
                                      -63-

Rule 14e-1 under the Exchange Act and any other securities laws
and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of
Notes pursuant to a Change of Control Offer.  To the extent the
provisions of any securities laws or regulations conflict with
the provisions under this Section 4.15, the Company shall
comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under this
Section 4.15 by virtue thereof.

            SECTION 4.16.  Limitation on Asset Sales.
                           -------------------------

            (a)   The Company shall not, and shall not permit any
of its Restricted Subsidiaries to, consummate an Asset Sale
unless (i) the Company or the applicable Restricted Subsidiary,
as the case may be, receives consideration at the time of such
Asset Sale at least equal to the fair market value of the
assets sold or otherwise disposed of (as determined in good

 
                                      -64-

faith by the Company's Board of Directors), (ii) at least 75%
of the consideration received by the Company or the Restricted
Subsidiary, as the case may be, from such Asset Sale shall be
cash or Cash Equivalents; provided that the amount of (a) any
liabilities (as shown on the Company's or such Restricted
Subsidiary's most recent balance sheet) of the Company or any
such Restricted Subsidiary (other than liabilities that are by
their terms subordinated to the Notes) that are assumed by the
transferee of any such assets, (b) any notes or other
obligations received by the Company or any such Restricted
Subsidiary from such transferee that are immediately converted
by the Company or such Restricted Subsidiary into cash (to the
extent of the cash received) and (c) any Designated Noncash
Consideration received by the Company or any of its Restricted
Subsidiaries in such Asset Sale having an aggregate fair market
value, taken together with all other Designated Noncash
Consideration received pursuant to this clause (c) that is at
that time outstanding (including any Designated Noncash
Consideration applied pursuant to the third paragraph of this
covenant), not to exceed 10% of Total Assets at the time of the
receipt of such Designated Noncash Consideration (with the fair
market value of each item of Designated Noncash Consideration
being measured at the time received and without giving effect
to subsequent changes in value), shall be deemed to be cash for
the purposes of this provision or for purposes of the third
paragraph of this covenant, and (iii) upon the consummation of
an Asset Sale, the Company shall apply, or cause such
Restricted Subsidiary to apply, the Net Cash Proceeds relating
to such Asset Sale within 365 days of receipt thereof either
(A) to prepay any Senior Debt and, in the case of any Senior
Debt under any revolving credit facility, effect a permanent
reduction in the availability under such revolving credit
facility, (B) to repurchase Existing Notes required to be
repurchased under the indenture governing the Existing Notes,
(C) to reinvest in Productive Assets, or (D) a combination of
prepayment, repurchase and investment permitted by the
foregoing clauses (iii)(A), (iii)(B) and (iii)(C).  Pending the
final application of any such Net Cash Proceeds, the Company or
such Restricted Subsidiary may temporarily reduce Indebtedness
under a revolving credit facility, if any, or otherwise invest
such Net Cash Proceeds in Cash Equivalents.  On the 366th day
after an Asset Sale or such earlier date, if any, as the Board
of Directors of the Company or of such Restricted Subsidiary
determines not to apply the Net Cash Proceeds relating to such
Asset Sale as set forth in clauses (iii)(A), (iii)(B), (iii)(C)
or (iii)(D) of the next preceding sentence (each, a "Net
Proceeds Offer Trigger Date"), such aggregate amount of Net
Cash Proceeds which 

 
                                      -65-

have not been applied on or before such Net Proceeds Offer
Trigger Date as permitted in clauses (iii)(A), (iii)(B),
(iii)(C) and (iii)(D) of the next preceding sentence (each a
"Net Proceeds Offer Amount") shall be applied by the Company or
such Restricted Subsidiary to make an offer to purchase (the
"Net Proceeds Offer") on a date (the "Net Proceeds Offer Payment
Date") not less than 30 nor more than 45 days following the
applicable Net Proceeds Offer Trigger Date, from all Holders on
a pro rata basis that amount of Notes equal to the Net Proceeds
  --- ----
Offer Amount at a price equal to 100% of the principal amount of
the Notes to be purchased, plus accrued interest thereon, if
any, to the date of purchase; provided, however, that if at any
                              --------  -------
time any non-cash consideration (including any Designated
Noncash Consideration) received by the Company or any Restricted
Subsidiary of the Company, as the case may be, in connection
with any Asset Sale is converted into or sold or otherwise
disposed of for cash (other than interest received with respect
to any such non-cash consideration), then such conversion or
disposition shall be deemed to constitute an Asset Sale
hereunder and the Net Cash Proceeds thereof shall be applied in
accordance with this covenant.

            Notwithstanding the foregoing, if a Net Proceeds 
Offer Amount is less than $10.0 million, the application of the
Net Cash Proceeds constituting such Net Proceeds Offer Amount to
a Net Proceeds Offer may be deferred until such time as such Net
Proceeds Offer Amount plus the aggregate amount of all Net
Proceeds Offer Amounts arising subsequent to the Net Proceeds
Offer Trigger Date relating to such initial Net Proceeds Offer
Amount from all Asset Sales by the Company and its Restricted
Subsidiaries aggregates at least $10.0 million, at which time the
Company or such Restricted Subsidiary shall apply all Net Cash
Proceeds constituting all Net Proceeds Offer Amounts that have
been so deferred to make a Net Proceeds Offer (the first date the
aggregate of all such deferred Net Proceeds Offer Amounts is
equal to $10.0 million or more shall be deemed to be a "Net
Proceeds Offer Trigger Date").

            Notwithstanding the two immediately preceding paragraphs, 
the Company and its Restricted Subsidiaries will be permitted to
consummate an Asset Sale without complying with such paragraphs
to the extent (i) at least 75% of the consideration for such
Asset Sale constitutes Productive Assets, cash, cash equivalents
and/or marketable securities (i.e., such securities which could
                              ----
be sold for cash within 180 days of the acquisition thereof) and
(ii) such Asset Sale is for fair market value (as determined in
good faith by the Company's Board

 
                                      -66-

of Directors); provided that any consideration not constituting
               --------
Productive Assets received by the Company or any of its
Restricted Subsidiaries in connection with any Asset Sale
permitted to be consummated under this paragraph shall be
subject to the provisions of the two preceding paragraphs.

            Each Net Proceeds Offer will be mailed to the 
record Holders as shown on the register of Holders within 25
days following the Net Proceeds Offer Trigger Date, with a copy
to the Trustee, and shall comply with the procedures set forth
in the Indenture. Upon receiving notice of the Net Proceeds
Offer, Holders may elect to tender their Notes in whole or in
part in integral multiples of $1,000 in exchange for cash. To
the extent Holders properly tender Notes in an amount exceeding
the Net Proceeds Offer Amount, Notes of tendering Holders will
be purchased on a pro rata basis (based on amounts tendered). A
                  --- ---- 
Net Proceeds Offer shall remain open for a period of 20 business
days or such longer period as may be required by law. To the
extent that the aggregate amount of Notes tendered pursuant to a
Net Proceeds Offer is less than the Net Proceeds Offer Amount,
the Company may use any remaining Net Proceeds Offer Amount for
general corporate purposes. Upon completion of any such Net
Proceeds Offer, the Net Proceeds Offer Amount shall be reset at
zero.

            The Company will comply with the requirements of 
Rule 14e-1 under the Exchange Act and any other securities laws
and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of
Notes pursuant to a Net Proceeds Offer. To the extent that the
provisions of any securities laws or regulations conflict with
the "Asset Sale" provisions of this Indenture, the Company shall
comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the
"Asset Sale" provisions of this Indenture by virtue thereof.

            (b) Subject to the deferral of the Net Proceeds Offer 
Trigger Date contained in the second paragraph of subsection (a)
above, each notice of a Net Proceeds Offer pursuant to this
Section 4.16 shall be mailed or caused to be mailed, by first
class mail, by the Company not more than 25 days after the Net
Proceeds Offer Trigger Date to all Holders at their last
registered addresses as of a date within 15 days of the mailing
of such notice, with a copy to the Trustee. The notice shall
contain all instructions and materials necessary to enable such
Holders to tender Notes pursuant to the Net Proceeds Offer and
shall state the following terms:

 
                                      -67-

            (1) that the Net Proceeds Offer is being made 
pursuant to Section 4.16 and that all Notes tendered will be
accepted for payment; provided, however, that if the aggregate
                      --------- ------- 
principal amount of Notes tendered in a Net Proceeds Offer plus
accrued interest at the expiration of such offer exceeds the
aggregate amount of the Net Proceeds Offer, the Company shall
select the Notes to be purchased on a pro rata basis (with such
                                      --- ----
adjustments as may be deemed appropriate by the Company so that
only Notes in denominations of $1,000 or multiples thereof shall
be purchased);

            (2)   the purchase price (including the amount 
of accrued interest) and the purchase date (which shall be 20
Business Days from the date of mailing of notice of such Net
Proceeds Offer, or such longer period as required by law) (the
"Proceeds Purchase Date"); provided that the Proceeds Purchase
                           --------
Date for the Notes shall be a date subsequent to any payment
dates for the purchase or other repayment of Senior Debt having
similar provisions;

            (3)   that any Note not tendered will continue to
      accrue interest;

            (4)   that, unless the Company defaults in making 
payment therefor, any Note accepted for payment pursuant to the
Net Proceeds Offer shall cease to accrue interest after the
Proceeds Purchase Date;

            (5)   that Holders electing to have a Note purchased 
pursuant to a Net Proceeds Offer will be required to surrender
the Note, with the form entitled "Option of Holder to Elect
Purchase" on the reverse of the Note completed, to the Paying
Agent at the address specified in the notice prior to the close
of business on the third Business Day prior to the Proceeds
Purchase Date;

            (6)   that Holders will be entitled to withdraw 
their election if the Paying Agent receives, not later than five
Business Days prior to the Proceeds Purchase Date, a telegram,
telex, facsimile transmission or letter setting forth the name
of the Holder, the principal amount of the Notes the Holder
delivered for purchase and a statement that such Holder is
withdrawing his election to have such Note purchased; and

 
                                      -68-

            (7)   that Holders whose Notes are purchased only 
in part will be issued new Notes in a principal amount equal to
the unpurchased portion of the Notes surrendered; provided that
                                                  --------
each Note purchased and each new Note issued shall be in an
original principal amount of $1,000 or integral multiples
thereof;

            On or before the Proceeds Purchase Date, the 
Company shall (i) accept for payment Notes or portions thereof
tendered pursuant to the Net Proceeds Offer which are to be
purchased in accordance with item (b)(1) above, (ii) deposit
with the Paying Agent U.S. Legal Tender sufficient to pay the
purchase price plus accrued interest, if any, of all Notes to be
purchased and (iii) deliver to the Trustee Notes so accepted
together with an Officers' Certificate stating the Notes or
portions thereof being purchased by the Company. The Paying
Agent shall promptly mail to the Holders of Notes so accepted
payment in an amount equal to the purchase price plus accrued
interest, if any. For purposes of this Section 4.16, the Trustee
shall act as the Paying Agent.

            Any amounts remaining after the purchase of Notes 
pursuant to a Net Proceeds Offer shall be returned by the
Trustee to the Company.

            The Company shall comply with the requirements of 
Rule 14e-1 under the Exchange Act and any other securities laws
and regulations thereunder to the extent such laws and
regulations are applicable in connection with the purchase of
Notes pursuant to a Net Proceeds Offer. To the extent the
provisions of any securities laws or regulations conflict with
the provisions of this Indenture relating to a Net Proceeds
Offer, the Company shall comply with the applicable securities
laws and regulations and shall not be deemed to have breached
its obligations relating to such Net Proceeds Offer by virtue
thereof.

            SECTION 4.17.  Limitation on Preferred
                           Stock of Subsidiaries. 
                           -----------------------

            The Company shall not permit any of its Restricted 
Subsidiaries to issue any Preferred Stock (other than to the
Company or to a Wholly Owned Restricted Subsidiary of the
Company) or permit any Person (other than the Company or a
Wholly Owned Restricted Subsidiary of the Company) to own any
Preferred Stock of any Restricted Subsidiary of the Company,
other than Permitted Foreign Subsidiary Preferred Stock and
Permitted Domestic Subsidiary Preferred Stock.

 
                                      -69-

            SECTION 4.18.  Limitation on Liens.
                           -------------------
            The Company shall not, and shall not permit any 
of its Restricted Subsidiaries to, create, incur, assume or
suffer to exist any Liens of any kind against or upon any of its
property or assets, or any proceeds therefrom, unless (i) in the
case of Liens securing Indebtedness that is expressly
subordinate or junior in right of payment to the Notes, the
Notes are secured by a Lien on such property, assets or proceeds
that is senior in priority to such Liens and (ii) in all other
cases, the Notes are equally and ratably secured, except for (A)
Liens existing as of the Issue Date and any extensions, renewals
or replacements thereof; (B) Liens securing Senior Debt; (C)
Liens securing the Notes; (D) Liens of the Company or a Wholly
Owned Restricted Subsidiary on assets of any Subsidiary of the
Company; (E) Liens securing Indebtedness which is incurred to
refinance Indebtedness which has been secured by a Lien
permitted under this Indenture and which has been incurred in
accordance with the provisions of this Indenture; provided,
                                                  --------
however, that such Liens do not extend to or cover any property
- -------
or assets of the Company or any of its Restricted Subsidiaries
not securing the Indebtedness so refinanced; and (F) Permitted
Liens.

            SECTION 4.19.  Limitation of Guarantees
                           by Subsidiaries.        
                           ------------------------

            The Company shall not permit any Restricted Subsidiary, 
directly or indirectly, by way of the pledge of any intercompany
note or otherwise, to assume, guarantee or in any other manner
become liable with respect to any Indebtedness of the Company or
any other Subsidiary (other than (A) Indebtedness and other

Indebtedness of a Restricted Subsidiary, (C) Indebtedness under
Currency Agreements in reliance on clause (vi) of the definition
of Permitted Indebtedness or (D) Interest Swap Obligations

Restricted Subsidiary executes and delivers a supplemental
indenture to the Indenture, providing a guarantee of payment of
the Notes by such Restricted Subsidiary (the "Guarantee") and
(b) (x) if any such assumption, guarantee or other liability of
such Restricted Subsidiary is provided in respect of Senior
Debt, the guarantee or other instrument provided by such
Restricted Subsidiary in respect of such Senior Debt may be
superior to the Guarantee pursuant to subordination provisions
no less favorable to the

 
                                      -70-

Holders of the Notes than those contained in the Indenture and
(y) if such assumption, guarantee or other liability of such
Restricted Subsidiary is provided in respect of Indebtedness
that is expressly subordinated to the Notes, the guarantee or
other instrument provided by such Restricted Subsidiary in
respect of such subordinated Indebtedness shall be subordinated
to the Guarantee pursuant to subordination provisions no less
favorable to the Holders of the Notes than those contained in
the Indenture.

            Notwithstanding the foregoing, any such Guarantee 
by a Restricted Subsidiary of the Notes shall provide by its
terms that it shall be automatically and unconditionally
released and discharged, without any further action required on
the part of the Trustee or any Holder, upon: (i) the
unconditional release of such Restricted Subsidiary from its
liability in respect of the Indebtedness in connection with
which such Guarantee was executed and delivered pursuant to the
preceding paragraph; or (ii) any sale or other disposition (by
merger or otherwise) to any Person which is not a Restricted
Subsidiary of the Company, of all of the Company's Capital Stock
in, or all or substantially all of the assets of, such
Restricted Subsidiary; provided that (a) such sale or

disposition of such Capital Stock or assets is otherwise in
compliance with the terms of the Indenture and (b) such
assumption, guarantee or other liability of such Restricted

Subsidiaries are engaged on the Issue Date.

            SECTION 5.01.  Merger, Consolidation
                           and Sale of Assets.  
                           ---------------------

            (a)   The Company shall not, in a single transaction 
or a series of related transactions, consolidate with or merge
with or into, or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its assets to,
another Person or Persons or adopt a Plan of Liquidation unless:

            (1)   either (A) the Company shall be the survivor 
of such merger or consolidation or (B) the surviving Person is a
corporation, partnership or trust organized and existing under
the laws of the United States, any state thereof or the District
of Columbia and such surviving Person shall expressly assume all
the obligations of the Company under the Notes and this
Indenture;

            (2)   immediately after giving effect to such 
transaction (on a pro forma basis, including any Indebtedness
incurred or anticipated to be incurred in connection with such
transaction), the Company or the surviving Person is able to
incur at least $1.00 of additional Indebtedness (other than
Permitted Indebtedness) in compliance with Section 4.12; and

            (b)   For purposes of the foregoing, the transfer 
(by lease, assignment, sale or otherwise, in a single
transaction or series of transactions) of all or substantially
all of the properties and assets of one or more Subsidiaries of
the Company, the Capital Stock of which constitutes all or
substantially all of the properties and assets of the Company,
shall be deemed to be the transfer of all or substantially all
of the properties and assets of the Company. Notwithstanding the
foregoing clauses (2) and (3), (a) any Restricted Subsidiary of
the Company may consolidate with, merge into or transfer all or

 
                                      -72-

part of its properties and assets to the Company and (b) the
Company may merge with an Affiliate incorporated solely for the
purpose of reincorporating the Company in another jurisdiction.

            SECTION 5.02.  Successor Corporation Substituted.
                           ---------------------------------

            Upon any consolidation, combination or merger or 
any transfer of all or substantially all of the assets of the
Company in accordance with the foregoing, the surviving entity
shall succeed to, and be substituted for, and may exercise every
right and power of, the Company under this Indenture and the
Notes with the same effect as if such surviving entity had been
named as such; provided that solely for purposes of computing
               --------
amounts described in clause (iii) of the first paragraph of
Section 4.10, any such surviving entity to the Company shall
only be deemed to have succeeded to and be substituted for the
Company with respect to periods subsequent to the effective time
of such merger, consolidation, combination or transfer of
assets.

                             DEFAULT AND REMEDIES


            SECTION 6.01.  Events of Default.
                           -----------------
            An "Event of Default" occurs if:

            (1)   the Company fails to pay interest on any 
Notes when the same becomes due and payable and the Default
continues for a period of 30 days (whether or not such payment
shall be prohibited by Article Ten of this Indenture); or

            (2)   the Company fails to pay the principal on any 
Notes when such principal becomes due and payable, at maturity,
upon redemption or otherwise (including the failure to make a
payment to purchase Notes tendered pursuant to a Change of
Control Offer or a Net Proceeds Offer) (whether or not such
payment shall be prohibited by Article Ten); or

            (3)   the Company defaults in the observance or 
performance of any other covenant or agreement contained in this
Indenture and which default continues for a period of

 
                                      -73-

default (and demanding that such default be remedied) from the
Trustee or the Holders of at least 25% of the outstanding
principal amount of the Notes; or

            (4) the Company fails to pay at final stated 
maturity (giving effect to any extensions thereof) the principal
amount of any Indebtedness of the Company or any Restricted
Subsidiary (other than a Securitization Entity) of the Company,
and such failure continues for a period of 20 days or more, or
the acceleration of the final stated maturity of any such
Indebtedness (which acceleration is not rescinded, annulled or
otherwise cured within 20 days of receipt by the Company or such
Restricted Subsidiary of notice of any such acceleration) if the
aggregate principal amount of such Indebtedness, together with
the principal amount of any other such Indebtedness in default
for failure to pay principal at final stated maturity or which
has been accelerated, in each case with respect to which the 20-
day period described above has passed, aggregates $20.0 million
or more at any time; or

            (5) one or more judgments in an aggregate amount in 
excess of $20.0 million shall have been rendered against the
Company or any of its Significant Subsidiaries and such
judgments remain undischarged, unpaid or unstayed for a period
of 60 days after such judgment or judgments become final and non-
appealable; or

            (6)   the Company or any Significant Subsidiary 
(A) commences a voluntary case or proceeding under any
Bankruptcy Law with respect to itself, (B) consents to the entry
of a judgment, decree or order for relief against it in an

in the institution of a bankruptcy or an insolvency proceeding
against it, (E) makes a general assignment for the benefit of

or any Significant Subsidiary in an involuntary case or
proceeding under any Bankruptcy Law, which shall (A) approve as
properly filed a petition seeking

 
                                      -74-

reorganization, arrangement, adjustment or composition in
respect of the Company or any Significant Subsidiary, (B)
appoint a Custodian of the Company or any Significant Subsidiary
or for substantially all of its property or (C) order the
winding-up or liquidation of its affairs; and such judgment,
decree or order shall remain unstayed and in effect for a period
of 60 consecutive days.

Any Event of Default shall not be deemed to have occurred under
clause (4) or (5) until the Trustee shall have received written
notice from the Company or any of the Holders or unless a Trust
Officer shall have actual knowledge of such Event of Default.

            SECTION 6.02.  Acceleration.
                           ------------

            (a)   If an Event of Default (other than an Event 
of Default specified in Section 6.01(6) or (7) with respect to
the Company) occurs and is continuing and has not been waived
pursuant to Section 6.04, then the Trustee or the Holders of at
least 25% in principal amount of outstanding Notes may declare
the principal of and accrued interest on all the Notes to be due
and payable by notice in writing to the Company and the Trustee
specifying the respective Event of Default and that it is a
"notice of acceleration" (the "Acceleration Notice"), and the
same (i) shall become immediately due and payable or (ii) if
there are any amounts outstanding under the Bank Credit
Agreement, shall become due and payable upon the first to occur
of an acceleration under the Bank Credit Agreement or 5 business
days after receipt by the Company and the Representative under
the Bank Credit Agreement of such Acceleration Notice but only
if such Event of Default is then continuing. Upon any such
declaration, but subject to the immediately preceding sentence,
such amount shall be immediately due and payable.

            (b)   If an Event of Default specified in 
Section 6.01(6) or (7) occurs with respect to the Company, all
unpaid principal and accrued interest on the Notes then
outstanding shall ipso facto become and be immediately due and
                  ---- -----
payable without any declaration or other act on the part of the
Trustee or any Noteholder.

            (c)   At any time after a declaration of acceleration 
with respect to the Notes in accordance with Section 6.02(a),
the Holders of a majority in principal amount of the Notes may
rescind and cancel such declaration and its consequences (i) if
the rescission would not conflict with any judgment or decree,
(ii) if all existing Events of Default have been cured or

 
                                      -75-

waived except nonpayment of principal or interest that has
become due solely because of the acceleration, (iii) to the
extent the payment of such interest is lawful, interest on
overdue installments of interest and overdue principal, which
has become due otherwise than by such declaration of
acceleration, has been paid, (iv) if the Company has paid the
Trustee its reasonable compensation and reimbursed the Trustee
for its expenses, disbursements and advances and (v) in the
event of the cure or waiver of an Event of Default of the type
described in Section 6.01(6) or (7), the Trustee shall have
received an Officers' Certificate and an Opinion of Counsel that
such Event of Default has been cured or waived. The holders of a
majority in principal amount of the Notes may waive any existing
Default or Event of Default under this Indenture, and its
consequences, except a default in the payment of the principal
of or interest on any Notes.

            SECTION 6.03.  Other Remedies.
                           --------------

            If an Event of Default occurs and is continuing, 
the Trustee may pursue any available remedy by proceeding at law
or in equity to collect the payment of principal of or interest
on the Notes or to enforce the performance of any provision of
the Notes or this Indenture.

            The Trustee may maintain a proceeding even if it 
does not possess any of the Notes or does not produce any of
them in the proceeding. A delay or omission by the Trustee or
any Noteholder in exercising any right or remedy accruing upon
an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.
No remedy is exclusive of any other remedy. All available
remedies are cumulative to the extent permitted by law.

            SECTION 6.04.  Waiver of Past Defaults.
                           -----------------------

            Subject to Sections 2.09, 6.07 and 9.02, the Holders
of a majority in principal amount of the outstanding Notes by
notice to the Trustee may waive an existing Default or Event of
Default and its consequences, except a Default in the payment
of principal of or interest on any Note as specified in clauses
(1) and (2) of Section 6.01.  When a Default or Event of
Default is waived, it is cured and ceases.

 
                                      -76-

            SECTION 6.05.  Control by Majority.
                           -------------------

            Subject to Section 2.09, the Holders of a majority in
principal amount of the outstanding Notes may direct the time,
method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power
conferred on it, including, without limitation, any remedies
provided for in Section 6.03.  Subject to Section 7.01,
however, the Trustee may refuse to follow any direction that
the Trustee reasonably believes conflicts with any law or this
Indenture, that the Trustee determines may be unduly
prejudicial to the rights of another Noteholder, or that may
involve the Trustee in personal liability; provided that the
                                           --------
Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction; and provided
                                                   --------
further that this provision shall not affect the rights of the
- -------
Trustee set forth in Section 7.01(d).

            SECTION 6.06.  Limitation on Suits.
                           -------------------

            A Noteholder may not pursue any remedy with respect
to this Indenture or the Notes unless:

            (1)   the Holder gives to the Trustee written notice
      of a continuing Event of Default;

            (2)   Holders of at least 25% in principal amount of
      the outstanding Notes make a written request to the
      Trustee to pursue the remedy;

            (3)   such Holders offer to the Trustee indemnity
      reasonably satisfactory to the Trustee against any loss,
      liability or expense to be incurred in compliance with
      such request;

            (4)   the Trustee does not comply with the request
      within 45 days after receipt of the request and the offer
      of satisfactory indemnity; and

            (5)   during such 45-day period the Holders of a
      majority in principal amount of the outstanding Notes do
      not give the Trustee a direction which, in the opinion of
      the Trustee, is inconsistent with the request.

            A Noteholder may not use this Indenture to prejudice
the rights of another Noteholder or to obtain a preference or
priority over such other Noteholder.

            SECTION 6.07.  Rights of Holders To Receive Payment.
                           ------------------------------------

            Notwithstanding any other provision of this
Indenture, the right of any Holder to receive payment of
principal of and interest on a Note, on or after the respective
due dates expressed in such Note, or to bring suit for the
enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of
such Holder.

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

            If an Event of Default in payment of principal or
interest specified in clause (1) or (2) of Section 6.01 occurs
and is continuing, the Trustee may recover judgment in its own
name and as trustee of an express trust against the Company or
any other obligor on the Notes for the whole amount of
principal and accrued interest remaining unpaid, together with
interest on overdue principal and, to the extent that payment
of such interest is lawful, interest on overdue installments of
interest at the rate set forth in Section 4.01 and such further

of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and
counsel.

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

            The Trustee may file such proofs of claim and other
papers or documents as may be necessary or advisable in order
to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, taxes, disbursements and
advances of the Trustee, its agents and counsel) and the
Noteholders allowed in any judicial proceedings relating to the
Company or any other obligor upon the Notes, any of their
respective creditors or any of their respective property and
shall be entitled and empowered to collect and receive any
monies or other property payable or deliverable on any such
claims and to distribute the same, and any Custodian in any
such judicial proceedings is hereby authorized by each
Noteholder to make such payments to the Trustee and, in the
event that the Trustee shall consent to the making of such
payments directly to the Noteholders, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses,
taxes, disbursements and advances of the Trustee, its agent and
counsel, and any other amounts due the Trustee under
Section 7.07.  The Company's payment obligations under this
Section 6.09 shall be secured in accordance with the provisions
of Section 7.07 

 
                                      -78-

hereunder. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on
behalf of any Noteholder any plan of reorganization,
arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Noteholder in any such
proceeding.

            SECTION 6.10.  Priorities.
                           ----------

            If the Trustee collects any money or property
pursuant to this Article Six, it shall pay out the money in the
following order:

            First:  to the Trustee for amounts due under
      Section 7.07;

      the Company directly without the Trustee, to Holders for
      their collection costs;

            Third:  to Holders for amounts due and unpaid on the
      Notes for principal and interest, ratably, without
      preference or priority of any kind, according to the
      amounts due and payable on the Notes for principal and
      interest, respectively; and

            Fourth:  to the Company or any other obligor on the
      Notes, as their interests may appear, or as a court of
      competent jurisdiction may direct.

            The Trustee, upon prior notice to the Company, may
fix a record date and payment date for any payment to
Noteholders pursuant to this Section 6.10.

            SECTION 6.11.  Undertaking for Costs.
                           ---------------------

            In any suit for the enforcement of any right or
remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in
its discretion may require the filing by any party litigant in
the suit of an undertaking to pay the costs of the suit, and
the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees, against any party
litigant in the suit, having due regard to the merits and good
faith of the claims or defenses made by the party litigant.
This Section 6.11 does not apply to a suit by the Trustee, a

                                  TRUSTEE


            SECTION 7.01.  Duties of Trustee.
                           -----------------

            (a)   If a Default or an Event of Default has occurred
and is continuing, the Trustee shall exercise such of the
rights and powers vested in it by this Indenture and use the
same degree of care and skill in its exercise thereof as a
prudent person would exercise or use under the circumstances in
the conduct of his own affairs.

            (b)   Except during the continuance of a Default or an
Event of Default:

            (1)   The Trustee need perform only those duties as
      are specifically set forth in this Indenture and no
      covenants or obligations shall be implied in this
      Indenture against the Trustee.

            (2)   In the absence of bad faith on its part, the
      Trustee may conclusively rely, as to the truth of the
      statements and the correctness of the opinions expressed
      therein, upon certificates or opinions furnished to the
      Trustee and conforming to the requirements of this
      Indenture.  However, the Trustee shall examine the
      certificates and opinions to determine whether or not they
      conform to the requirements of this Indenture.

            (c)   Notwithstanding anything to the contrary herein
contained, the Trustee may not be relieved from liability for
its own negligent action, its own negligent failure to act, or
its own willful misconduct, except that:

            (1)   This paragraph does not limit the effect of
      paragraph (b) of this Section 7.01.

            (2)   The Trustee shall not be liable for any error of
      judgment made in good faith by a Trust Officer, unless it

 
                                      -80-

      is proved that the Trustee was negligent in ascertaining
      the pertinent facts.

            (3)   The Trustee shall not be liable with respect to
      any action it takes or omits to take in good faith in
      accordance with a direction received by it pursuant to
      Section 6.02, 6.04 or 6.05.

            (d)   No provision of this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties
hereunder or in the exercise of any of its rights or powers if
it shall have reasonable grounds for believing that repayment
of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it.

            (e)   Whether or not herein expressly provided, every
provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (a), (b), (c) and (d) of this
Section 7.01.

            (f)   The Trustee shall not be liable for interest on
any money or assets received by it except as the Trustee may
agree in writing with the Company.  Assets held in trust by the
Trustee need not be segregated from other assets except to the
extent required by law.

            SECTION 7.02.  Rights of Trustee.
                           -----------------

            Subject to Section 7.01:

            (a)   The Trustee may rely and shall be fully
      protected in acting or refraining from acting upon any
      resolution, certificate, statement, instrument, opinion,
      report, notice, request, direction, consent, order, bond,
      note or other paper or document believed by it to be
      genuine and to have been signed or presented by the proper
      Person.  The Trustee need not investigate any fact or
      matter stated in the document.

            (b)   Before the Trustee acts or refrains from acting,
      it may consult with counsel and may require an Officers'
      Certificate, an Opinion of Counsel or both, which shall
      conform to Sections 11.04 and 11.05.  The Trustee shall
      not be liable for any action it takes or omits to take in
      good faith in reliance on such Officers' Certificate or
      Opinion of Counsel.

 
                                      -81-

            (c)   The Trustee may execute any of the trusts or
      powers hereunder or perform any duties hereunder either
      directly or indirectly or by or through agents or
      attorneys and the Trustee shall not be responsible for the
      misconduct or negligence of any agent or attorney
      appointed with due care.

            (d)   The Trustee shall not be liable for any action
      that it takes or omits to take in good faith which it
      reasonably believes to be authorized or within its rights
      or powers.

            (e)   The Trustee shall not be bound to make any
      investigation into the facts or matters stated in any
      resolution, certificate, statement, instrument, opinion,
      notice, request, direction, consent, order, bond,
      debenture, or other paper or document, but the Trustee, in
      its discretion, may make such further inquiry or
      investigation into such facts or matters as it may see
      fit, and, if the Trustee shall determine to make such
      further inquiry or investigation, it shall be entitled,
      upon reasonable notice to the Company, to examine the
      books, records, and premises of the Company, personally or
      by agent or attorney and to consult with the officers and
      representatives of the Company, including the Company's
      accountants and attorneys.

            (f)   The Trustee shall be under no obligation to
      exercise any of the rights or powers vested in it by this
      Indenture at the request, order or direction of any of the
      Holders pursuant to the provisions of this Indenture,
      unless such Holders shall have offered to the Trustee
      security or indemnity reasonably satisfactory to the
      Trustee against the costs, expenses and liabilities which
      may be incurred by it in compliance with such request,
      order or direction.

            (g)   The Trustee shall not be required to give any
      bond or surety in respect of the performance of its powers
      and duties hereunder.

            SECTION 7.03.  Individual Rights of Trustee.
                           ----------------------------

            The Trustee in its individual or any other capacity
may become the owner or pledgee of Notes and may otherwise deal
with the Company, any Subsidiary of the Company, or their
respective Affiliates with the same rights it would have if it

 
                                      -82-

were not Trustee.  Any Agent may do the same with like rights.
However, the Trustee must comply with Sections 7.10 and 7.11.

            SECTION 7.04.  Trustee's Disclaimer.
                           --------------------

            The recitals contained herein and in the Notes shall
be taken as statements of the Company and the Trustee assumes
no responsibility for their correctness.  The Trustee makes no
representation as to the validity or adequacy of this Indenture
or the Notes, and it shall not be accountable for the Company's
use of the proceeds from the Notes, and it shall not be
responsible for any statement of the Company in this Indenture
or the Notes other than the Trustee's certificate of
authentication.

            SECTION 7.05.  Notice of Default.
                           -----------------

            If a Default or an Event of Default occurs and is
continuing and if it is known to the Trustee, the Trustee shall
mail to each Noteholder notice of the uncured Default or Event
of Default within 90 days after such Default or Event of
Default occurs.  Except in the case of a Default or an Event of
Default in payment of principal of, or interest on, any Note,
including an accelerated payment and the failure to make
payment on the Change of Control Payment Date pursuant to a
Change of Control Offer or on the Proceeds Purchase Date
pursuant to a Net Proceeds Offer and, except in the case of a
failure to comply with Article V hereof, the Trustee may
withhold the notice if and so long as its Board of Directors,
the executive committee of its Board of Directors or a
committee of its directors and/or Trust Officers in good faith
determines that withholding the notice is in the interest of
the Noteholders.

            SECTION 7.06.  Reports by Trustee to Holders.
                           -----------------------------

            Within 60 days after each May 15, the Trustee shall,
to the extent that any of the events described in TIA (S) 313(a)
occurred within the previous twelve months, but not otherwise,
mail to each Noteholder a brief report dated as of such date
that complies with TIA (S) 313(a).  The Trustee also shall comply
with TIA (S)(S) 313(b), (c) and (d).

            A copy of each report at the time of its mailing to
Noteholders shall be mailed to the Company and filed with the
SEC and each stock exchange, if any, on which the Notes are
listed.

 
                                      -83-

            The Company shall promptly notify the Trustee if the
Notes become listed on any stock exchange and the Trustee shall
comply with TIA (S) 313(d).

            SECTION 7.07.  Compensation and Indemnity.
                           --------------------------

            The Company shall pay to the Trustee from time to
time reasonable compensation for its services.  The Trustee's
compensation shall not be limited by any law on compensation of
a trustee of an express trust.  The Company shall reimburse the
Trustee upon request for all reasonable fees and expenses,
including out-of-pocket expenses incurred or made by it in
connection with the performance of its duties under this
Indenture.  Such expenses shall include the reasonable fees and
expenses of the Trustee's agents and counsel.

            The Company shall indemnify the Trustee and its
agents, employees, stockholders and directors and officers for,
and hold them harmless against, any loss, liability or expense
incurred by them except for such actions to the extent caused
by any negligence, bad faith or willful misconduct on their
part, arising out of or in connection with the administration
of this trust including the reasonable costs and expenses of
defending themselves against any claim or liability in
connection with the exercise or performance of any of their
rights, powers or duties hereunder.  The Trustee shall notify
the Company promptly of any claim asserted against the Trustee
for which it may seek indemnity.  At the Trustee's sole
discretion, the Company shall defend the claim and the Trustee
shall cooperate and may participate in the defense; provided
                                                    --------
that any settlement of a claim shall be approved in writing by
the Trustee.  Alternatively, the Trustee may at its option have
separate counsel of its own choosing and the Company shall pay
the reasonable fees and expenses of such counsel; provided that
                                                  --------
the Company will not be required to pay such fees and expenses
if it assumes the Trustee's defense and there is no conflict of
interest between the Company and the Trustee in connection with
such defense as reasonably determined by the Trustee.  The
Company need not pay for any settlement made without its
written consent.  The Company need not reimburse any expense or
indemnify against any loss or liability to the extent incurred
by the Trustee through its negligence, bad faith or willful
misconduct.

            To secure the Company's payment obligations in this
Section 7.07, the Trustee shall have a lien prior to the Notes
on all assets or money held or collected by the Trustee, in its

 
                                      -84-

capacity as Trustee, except assets or money held in trust to
pay principal of or interest on particular Notes.  The
Trustee's right to receive payment of any amounts due under
this Section 7.07 shall not be subordinate to any other
liability or indebtedness of the Company (even though the Notes
may be subordinate to such other liability or indebtedness).

            When the Trustee incurs expenses or renders services
after an Event of Default specified in Section 6.01(6) or (7)
occurs, such expenses and the compensation for such services
are intended to constitute expenses of administration under any
Bankruptcy Law; provided, however, that this shall not affect
                --------  -------
the Trustee's rights as set forth in the preceding paragraph or
Section 6.10.

            SECTION 7.08.  Replacement of Trustee.
                           ----------------------

            The Trustee may resign by so notifying the Company.
The Holders of a majority in principal amount of the outstand-
ing Notes may remove the Trustee by so notifying the Company
and the Trustee and may appoint a successor Trustee.  The
Company may remove the Trustee if:

            (1)   the Trustee fails to comply with Section 7.10;

            (2)   the Trustee is adjudged bankrupt or insolvent;

            (3)   a receiver or other public officer takes charge
      of the Trustee or its property; or

            (4)   the Trustee becomes incapable of acting.

            If the Trustee resigns or is removed or if a vacancy
exists in the office of Trustee for any reason, the Company
shall notify each Holder of such event and shall promptly
appoint a successor Trustee.  Within one year after the
successor Trustee takes office, the Holders of a majority in
principal amount of the Notes may appoint a successor Trustee
to replace the successor Trustee appointed by the Company.

            A successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to
the Company.  Immediately after that, the retiring Trustee
shall transfer all property held by it as Trustee to the
successor Trustee, subject to the lien provided in
Section 7.07, the resignation or removal of the retiring
Trustee shall become effective, and the successor Trustee shall
have all the rights, 

 
                                      -85-

powers and duties of the Trustee under this Indenture. A
successor Trustee shall mail notice of its succession to each
Noteholder.

            If a successor Trustee does not take office within 60
days after the retiring Trustee resigns or is removed, the
retiring Trustee, the Company or the Holders of at least 10% in
principal amount of the outstanding Notes may petition any
court of competent jurisdiction for the appointment of a
successor Trustee.

            If the Trustee fails to comply with Section 7.10, any
Noteholder may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor
Trustee.

            Notwithstanding replacement of the Trustee pursuant
to this Section 7.08, the Company's obligations under Section
7.07 shall continue for the benefit of the retiring Trustee.

            SECTION 7.09.  Successor Trustee by Merger, Etc.
                           --------------------------------

            If the Trustee consolidates with, merges or converts
into, or transfers all or substantially all of its corporate
trust business to, another corporation, the resulting,
surviving or transferee corporation without any further act
shall, if such resulting, surviving or transferee corporation
is otherwise eligible hereunder, be the successor Trustee;
provided that such corporation shall be otherwise qualified and
- --------
eligible under this Article Seven.

            SECTION 7.10.  Eligibility; Disqualification.
                           -----------------------------

            This Indenture shall always have a Trustee who
satisfies the requirement of TIA (S)(S) 310(a)(1), (2) and (5).
The Trustee (or, in the case of a corporation included in a
bank holding company system, the related bank holding company)
shall have a combined capital and surplus of at least $50
million as set forth in its most recent published annual report
of condition.  In addition, if the Trustee is a corporation
included in a bank holding company system, the Trustee,
independently of such bank holding company, shall meet the
capital requirements of TIA (S) 310(a)(2).  The Trustee shall
comply with TIA (S) 310(b); provided, however, that there shall
                            --------  -------
be excluded from the operation of TIA (S) 310(b)(1) any indenture
or indentures under which other securities, or certificates of
interest or participation in other securities, of the Company
are 

 
                                      -86-

outstanding, if the requirements for such exclusion set
forth in TIA (S) 310(b)(1) are met.  The provisions of TIA (S) 310
shall apply to the Company, as obligor of the Notes.

            SECTION 7.11.  Preferential Collection of
                           Claims Against Company.
                           --------------------------

            The Trustee shall comply with TIA (S) 311(a), excluding
any creditor relationship listed in TIA (S) 311(b).  A Trustee
who has resigned or been removed shall be subject to TIA
(S) 311(a) to the extent indicated therein.  The provisions of
TIA (S) 311 shall apply to the Company, as obligor on the Notes.

                    DISCHARGE OF INDENTURE; DEFEASANCE


            SECTION 8.01.  Termination of the 
                           Company's Obligations.
                           ---------------------

            The Company may terminate its obligations under the
Notes and this Indenture, except those obligations referred to
in the penultimate paragraph of this Section 8.01, if all Notes
previously authenticated and delivered (other than destroyed,
lost or stolen Notes which have been replaced or paid or Notes
for whose payment U.S. Legal Tender has theretofore been
deposited with the Trustee or the Paying Agent in trust or
segregated and held in trust by the Company and thereafter
repaid to the Company, as provided in Section 8.05) have been
delivered to the Trustee for cancellation and the Company has
paid all sums payable by it hereunder, or if:

            (a)   either (i) pursuant to Article Three, the
      Company shall have given notice to the Trustee and mailed
      a notice of redemption to each Holder of the redemption of
      all of the Notes under arrangements satisfactory to the
      Trustee for the giving of such notice or (ii) all Notes
      have otherwise become due and payable hereunder;

            (b)   the Company shall have irrevocably deposited or
      caused to be deposited with the Trustee or a trustee
      satisfactory to the Trustee, under the terms of an
      irrevocable trust agreement in form and substance
      satisfactory to the Trustee, as trust funds in trust
      solely for the benefit of the Holders for that purpose,
      U.S. Legal Tender 

 
                                      -87-

      in such amount as is sufficient without consideration of
      reinvestment of such interest, to pay principal of, premium, if
      any, and interest on the outstanding Notes to maturity or
      redemption; provided that the Trustee shall have been irrevocably

      instructed to apply such U.S. Legal Tender to the payment of said
      principal, premium, if any, and interest with respect to the Notes
      and, provided, further, that from and after the time of deposit,
           --------  -------
      the money deposited shall not be subject to the rights of holders
      of Senior Debt pursuant to the provisions of Article Ten;

            (c)   no Default or Event of Default with respect to
      this Indenture or the Notes shall have occurred and be
      continuing on the date of such deposit or shall occur as a
      result of such deposit and such deposit will not result in
      a breach or violation of, or constitute a default under,
      any other instrument to which the Company is a party or by
      which it is bound;

            (d)   the Company shall have paid all other sums
      payable by it hereunder; and

            (e)   the Company shall have delivered to the Trustee
      an Officers' Certificate and an Opinion of Counsel, each
      stating that all conditions precedent providing for the
      termination of the Company's obligations under the Notes
      and this Indenture have been complied with.  Such Opinion
      of Counsel shall also state that such satisfaction and
      discharge does not result in a default under the Bank
      Credit Agreement (if then in effect) or any other
      agreement or instrument then known to such counsel that
      binds or affects the Company.

            Notwithstanding the foregoing paragraph, the

            After such delivery or irrevocable deposit, the
Trustee upon request shall acknowledge in writing the discharge
of the Company's obligations under the Notes and this Indenture
except for those surviving obligations specified above.

            SECTION 8.02.     Legal Defeasance and
                              Covenant Defeasance.
                              -------------------

            (a)   The Company may, at its option by Board
Resolution of the Board of Directors of the Company, at any
time, elect to have either paragraph (b) or (c) below be
applied to all outstanding Notes upon compliance with the
conditions set forth in Section 8.03.

            (b)   Upon the Company's exercise under paragraph (a)
hereof of the option applicable to this paragraph (b), the
Company shall, subject to the satisfaction of the conditions
set forth in Section 8.03, be deemed to have been discharged
from its obligations with respect to all outstanding Notes on
the date the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance").  For this purpose, Legal
Defeasance means that the Company shall be deemed to have paid
and discharged the entire Indebtedness represented by the
outstanding Notes, which shall thereafter be deemed to be
"outstanding" only for the purposes of Section 8.04 hereof and
the other Sections of this Indenture referred to in (i) and
(ii) below, and to have satisfied all its other obligations
under such Notes and this Indenture (and the Trustee, on demand
of and at the expense of the Company, shall execute proper
instruments acknowledging the same), and Holders of the Notes
and any amounts deposited under Section 8.03 hereof shall cease
to be subject to any obligations to, or the rights of, any
holder of Senior Debt under Article Ten or otherwise, except
for the following provisions, which shall survive until
otherwise terminated or discharged hereunder:  (i) the rights
of Holders of outstanding Notes to receive solely from the
trust fund described in Section 8.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal
of and interest on such Notes when such payments are due, (ii)
the Company's obligations with respect to such Notes under
Article Two and Section 4.02 hereof, (iii) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and the
Company's obligations in connection therewith and (iv) this
Article Eight.  Subject to compliance with this Article Eight,
the Company may exercise its option under this paragraph (b)
notwithstanding the prior exercise of its option under
paragraph (c) hereof.

            (c)   Upon the Company's exercise under paragraph (a)
hereof of the option applicable to this paragraph (c), the
Company shall, subject to the satisfaction of the conditions
set forth in Section 8.03 hereof, be released from its
obligations under the covenants contained in Sections 4.10
through 4.20 and 

 
                                      -89-

Article Five hereof with respect to the outstanding Notes on and
after the date the conditions set forth below are satisfied
(hereinafter, "Covenant Defeasance"), and the Notes shall
thereafter be deemed not "outstanding" for the purposes of any
direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such
covenants, but shall continue to be deemed "outstanding" for all
other purposes hereunder (it being understood that such Notes
shall not be deemed outstanding for accounting purposes) and
Holders of the Notes and any amounts deposited under Section
8.03 hereof shall cease to be subject to any obligations to, or
the rights of, any holder of Senior Debt under Article Ten or
otherwise. For this purpose, such Covenant Defeasance means
that, with respect to the outstanding Notes, the Company may
omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein
or in any other document and such omission to comply shall not
constitute a Default or an Event or Default under Section
6.01(3) hereof, but, except as specified above, the remainder of
this Indenture and such Notes shall be unaffected thereby. In
addition, upon the Company's exercise under paragraph (a) hereof
of the option applicable to this paragraph (c), subject to the
satisfaction of the conditions set forth in Section 8.03 hereof,
Sections 6.01(3), 6.01(4) and 6.01(5) shall not constitute
Events of Default.

            SECTION 8.03.     Conditions to Legal Defeasance               
                              or Covenant Defeasance.
                              ------------------------------

            The following shall be the conditions to the
application of either Section 8.02(b) or 8.02(c) hereof to the
outstanding Notes:

      In order to exercise either Legal Defeasance or Covenant
      Defeasance:

            (a) the Company must irrevocably deposit with the
      Trustee, in trust, for the benefit of the Holders, U.S.
      Legal Tender or U.S. Government Obligations, or a
      combination thereof, in such amounts as will be
      sufficient, in the opinion of a nationally recognized firm
      of independent public accountants, to pay the principal of
      and interest on the Notes on the stated date for payment
      thereof or on the applicable redemption date, as the case
      may be, of 

 
                                      -90-

      such principal or installment of principal of or 
      interest on the Notes; provided that the Trustee shall
                             --------
      have received an irrevocable written order from the
      Company instructing the Trustee to apply such U.S. Legal
      Tender or the proceeds of such U.S. Government Obligations
      to said payments with respect to the Notes;

            (b) in the case of an election under Section 8.02(b)
      hereof, the Company shall have delivered to the Trustee an
      Opinion of Counsel in the United States reasonably
      acceptable to the Trustee confirming that (A) the Company
      has received from, or there has been published by, the
      Internal Revenue Service a ruling or (B) since the date of
      this Indenture, there has been a change in the applicable
      federal income tax law, in either case to the effect that,
      and based thereon such Opinion of Counsel shall confirm
      that, the Holders of the Notes will not recognize income,
      gain or loss for federal income tax purposes as a result
      of such Legal Defeasance and will be subject to federal
      income tax on the same amounts, in the same manner and at
      the same times as would have been the case if such Legal
      Defeasance had not occurred;

            (c) in the case of an election under Section 8.02(c)
      hereof, the Company shall have delivered to the Trustee an
      Opinion of Counsel in the United States reasonably
      acceptable to the Trustee confirming that the Holders of
      the Notes will not recognize income, gain or loss for
      federal income tax purposes as a result of such Covenant
      Defeasance and will be subject to federal income tax on
      the same amounts, in the same manner and at the same times
      as would have been the case if such Covenant Defeasance
      had not occurred;

            (d) no Default or Event of Default or event which
      with notice or lapse of time or both would become a
      Default or an Event of Default with respect to the Notes
      shall have occurred and be continuing on the date of such
      deposit (other than a Default or Event of Default
      resulting from the incurrence of Indebtedness all or a
      portion of the proceeds of which will be used to defease
      the Notes pursuant to this Article Eight concurrently with
      such incurrence) or insofar as Sections 6.01(6) and
      6.01(7) hereof are concerned, at any time in the period
      ending on the 91st day after the date of such deposit;

 
                                      -91-

            (e) such Legal Defeasance or Covenant Defeasance
      shall not result in a breach or violation of or constitute
      a default under this Indenture or any other material
      agreement or instrument to which the Company or any of its
      Subsidiaries is a party or by which the Company or any of
      its Subsidiaries is bound;

            (f) the Company shall have delivered to the Trustee
      an Officers' Certificate stating that the deposit was not
      made by the Company with the intent of preferring the
      Holders over any other creditors of the Company or with
      the intent of defeating, hindering, delaying or defrauding
      any other creditors of the Company;

            (g) the Company shall have delivered to the Trustee
      an Officers' Certificate and an Opinion of Counsel, each
      stating that all conditions precedent provided for or
      relating to the Legal Defeasance or the Covenant
      Defeasance have been complied with; and 

            (h) the Company shall have delivered to the Trustee
      an Opinion of Counsel to the effect that (i) the trust
      funds will not be subject to any rights of any holders of
      Indebtedness of the Company other than the Notes, and
      (ii) assuming no intervening bankruptcy or insolvency of
      the Company between the date of deposit and the 91st day
      following the deposit and that no Holder is an insider of
      the Company, after the 91st day following the deposit, the
      trust funds will not be subject to the effect of any
      applicable Bankruptcy Law.

            SECTION 8.04.   Application of Trust Money.
                            --------------------------

            The Trustee or Paying Agent shall hold in trust U.S.
Legal Tender or U.S. Government Obligations deposited with it
pursuant to Article Eight, and shall apply the deposited U.S.
Legal Tender and the money from U.S. Government Obligations in
accordance with this Indenture to the payment of principal of
and interest on the Notes.  The Trustee shall be under no
obligation to invest said U.S. Legal Tender or U.S. Government
Obligations except as it may agree with the Company.

            The Company shall pay and indemnify the Trustee
against any tax, fee or other charge imposed on or assessed
against the U.S. Legal Tender or U.S. Government Obligations
deposited pursuant to Section 8.03 hereof or the principal and
interest received in respect thereof other than any such tax,

 
                                      -92-

fee or other charge which by law is for the account of the
Holders of the outstanding Notes.

            Anything in this Article Eight to the contrary
notwithstanding, the Trustee shall deliver or pay to the
Company from time to time upon the Company's request any
U.S. Legal Tender or U. S. Government Obligations held by it as
provided in Section 8.03 hereof which, in the opinion of a
nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the
Trustee, are in excess of the amount thereof that would then be
required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

            SECTION 8.05.   Repayment to the Company.
                            ------------------------

            Subject to Article Eight, the Trustee and the Paying
Agent shall promptly pay to the Company upon request any excess
U.S. Legal Tender or U.S. Government Obligations held by them
at any time and thereupon shall be relieved from all liability
with respect to such money.  The Trustee and the Paying Agent
shall pay to the Company upon request any money held by them
for the payment of principal or interest that remains unclaimed
for two years; provided that the Trustee or such Paying Agent,
               --------
before being required to make any payment, may at the expense
of the Company cause to be published once in a newspaper of
general circulation in the City of New York or mail to each
Holder entitled to such money notice that such money remains
unclaimed and that after a date specified therein which shall
be at least 30 days from the date of such publication or
mailing any unclaimed balance of such money then remaining will
be repaid to the Company.  After payment to the Company,
Noteholders entitled to such money must look to the Company for
payment as general creditors unless an applicable law
designates another Person.

            SECTION 8.06.  Reinstatement.
                           -------------

            If the Trustee or Paying Agent is unable to apply any
U.S. Legal Tender or U.S. Government Obligations in accordance
with Article Eight by reason of any legal proceeding or by
reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and
the Notes shall be revived and reinstated as though no deposit
had occurred pursuant to Article Eight until such time as the
Trustee or Paying Agent is permitted to apply all such U.S.

 
                                      -93-

Legal Tender or U.S. Government Obligations in accordance with
Article Eight; provided that if the Company has made any
               --------
payment of interest on or principal of any Notes because of the
reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to
receive such payment from the U.S. Legal Tender or U.S.
Government Obligations held by the Trustee or Paying Agent.

            SECTION 9.01.  Without Consent of Holders.
                           --------------------------

            The Company, when authorized by a Board Resolution,
and the Trustee, together, may amend or supplement this
Indenture or the Notes without notice to or consent of any
Noteholder:

            (1)   to cure any ambiguity, defect or inconsistency;
      provided that such amendment or supplement does not, in
      --------
      the opinion of the Trustee, adversely affect the rights of
      any Holder in any material respect;

            (2)   to comply with Article Five;

            (3)   to provide for uncertificated Notes in addition
      to or in place of certificated Notes;

            (4)   to comply with any requirements of the SEC in
      order to effect or maintain the qualification of this
      Indenture under the TIA; 

            (5)   to make any change that would provide any
      additional benefit or rights to the Noteholders or that
      does not adversely affect the rights of any Noteholder;

            (6)   to provide for issuance of the Exchange Notes,
      which will have terms substantially identical in all
      material respects to the Initial Notes (except that the
      transfer restrictions contained in the Initial Notes will
      be modified or eliminated, as appropriate), and which will
      be treated together with any outstanding Initial Notes, as
      a single issue of securities; or

 
                                      -94-

            (7)   to make any other change that does not, in the
      opinion of the Trustee, adversely affect in any material
      respect the rights of any Noteholders hereunder;

provided that the Company has delivered to the Trustee an
- --------
Opinion of Counsel stating that such amendment or supplement
complies with the provisions of this Section 9.01.

            SECTION 9.02.  With Consent of Holders.
                           -----------------------

            Subject to Section 6.07, the Company, when authorized
by a Board Resolution, and the Trustee, together, with the
written consent of the Holder or Holders of at least a majority
in aggregate principal amount of the outstanding Notes, may
amend or supplement this Indenture or the Notes, without notice
to any other Noteholders.  Subject to Section 6.07, the Holder
or Holders of a majority in aggregate principal amount of the
outstanding Notes may waive compliance by the Company with any
provision of this Indenture or the Notes without notice to any
other Noteholder.  No amendment, supplement or waiver,
including a waiver pursuant to Section 6.04, shall, without the
consent of each Holder of each Note affected thereby:

            (1)   reduce the amount of Notes whose Holders must
      consent to an amendment;

            (2)   reduce the rate of or change or have the effect
      of changing the time for payment of interest, including
      defaulted interest, on any Notes;

            (3)   reduce the principal of or change or have the
      effect of changing the fixed maturity of any Notes, or
      change the date on which any Notes may be subject to
      redemption or repurchase, or reduce the redemption or
      repurchase price therefor;

            (4)   make any Notes payable in money other than that
      stated in the Notes;

            (5)   make any change in provisions of this Indenture
      protecting the right of each Holder to receive payment of
      principal of and interest on such Note on or after the due
      date thereof or to bring suit to enforce such payment,
      permitting holders of a majority in principal amount of
      Notes to waive Defaults or Events of Default, other than
      ones with respect to the payment of principal of or

 
                                      -95-

      interest on the Notes, or relating to certain amendments
      of this Indenture;

            (6)   amend, modify or change in any material respect
      the obligation of the Company to make or consummate a
      Change of Control Offer in the event of a Change of
      Control or make and consummate a Net Proceeds Offer in
      respect of any Asset Sale that has been consummated or
      modify any of the provisions or definitions with respect
      thereto after a Change of Control has occurred or the
      subject Asset Sale has been consummated; or

            (7)   modify Article Ten or the definitions used in
      Article Ten to adversely affect the Holders of the Notes
      in any material respect.

            It shall not be necessary for the consent of the
Holders under this Section to approve the particular form of
any proposed amendment, supplement or waiver, but it shall be
sufficient if such consent approves the substance thereof.

            After an amendment, supplement or waiver under this
Section 9.02 becomes effective, the Company shall mail to the
Holders affected thereby a notice briefly describing the
amendment, supplement or waiver.  Any failure of the Company to
mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental
indenture.

            SECTION 9.03.  Effect on Senior Debt.
                           ---------------------

            No amendment of this Indenture shall adversely affect
the rights of any holder of Senior Debt under Article Ten of
this Indenture, without the consent of such holder.

            SECTION 9.04.  Compliance with TIA.
                           -------------------

            Every amendment, waiver or supplement of this
Indenture or the Notes shall comply with the TIA as then in
effect.

            SECTION 9.05.  Revocation and Effect of Consents.
                           ---------------------------------

            Until an amendment, waiver or supplement becomes
effective, a consent to it by a Holder is a continuing consent
by the Holder and every subsequent Holder of a Note or portion
of a Note that evidences the same debt as the consenting
Holder's Note, even if notation of the consent is not made on
any 

 
                                      -96-

Note.  Subject to the following paragraph, any such Holder
or subsequent Holder may revoke the consent as to such Holder's
Note or portion of such Note by notice to the Trustee or the
Company received before the date on which the Trustee receives
an Officers' Certificate certifying that the Holders of the
requisite principal amount of Notes have consented (and not
theretofore revoked such consent) to the amendment, supplement
or waiver.

            The Company may, but shall not be obligated to, fix a
record date for the purpose of determining the Holders entitled
to consent to any amendment, supplement or waiver, which record
date shall be at least 30 days prior to the first solicitation
of such consent.  If a record date is fixed, then
notwithstanding the last sentence of the immediately preceding
paragraph, those Persons who were Holders at such record date
(or their duly designated proxies), and only those Persons,
shall be entitled to revoke any consent previously given,
whether or not such Persons continue to be Holders after such
record date.  No such consent shall be valid or effective for
more than 90 days after such record date. 

            After an amendment, supplement or waiver becomes
effective, it shall bind every Noteholder, unless it makes a
change described in any of clauses (1) through (7) of Section
9.02, in which case, the amendment, supplement or waiver shall
bind only each Holder of a Note who has consented to it and
every subsequent Holder of a Note or portion of a Note that
evidences the same debt as the consenting Holder's Note;
provided that any such waiver shall not impair or affect the
- --------
right of any Holder to receive payment of principal of and
interest on a Note, on or after the respective due dates
expressed in such Note, or to bring suit for the enforcement of
any such payment on or after such respective dates without the
consent of such Holder.

            SECTION 9.06.  Notation on or Exchange of Notes.
                           --------------------------------

            If an amendment, supplement or waiver changes the
terms of a Note, the Trustee may require the Holder of the Note
to deliver it to the Trustee.  The Trustee may place an
appropriate notation on the Note about the changed terms and
return it to the Holder.  Alternatively, if the Company or the
Trustee so determines, the Company in exchange for the Note
shall issue and the Trustee shall authenticate a new Note that
reflects the changed terms.  Any such notation or exchange
shall be made at the sole cost and expense of the Company.

 
                                      -97-

            SECTION 9.07.  Trustee To Sign Amendments, Etc.
                           -------------------------------

            The Trustee shall execute any amendment, supplement
or waiver authorized pursuant to this Article Nine; provided
                                                    --------
that the Trustee may, but shall not be obligated to, execute
any such amendment, supplement or waiver which affects the
Trustee's own rights, duties or immunities under this
Indenture.  The Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Opinion of Counsel and
an Officers' Certificate each stating that the execution of any
amendment, supplement or waiver authorized pursuant to this
Article Nine is authorized or permitted by this Indenture.
Such Opinion of Counsel shall not be an expense of the Trustee.

            The Company covenants and agrees, and the Trustee and
each Holder of the Notes, by its acceptance thereof, likewise
covenants and agrees, that all Notes shall be issued subject to
the provisions of this Article Ten; and the Trustee and each
Person holding any Note, whether upon original issue or upon
transfer, assignment or exchange thereof, accepts and agrees
that the payment of all Obligations on the Notes by the Company
shall, to the extent and in the manner herein set forth, be
subordinated and junior in right of payment to the prior
payment in full in cash or Cash Equivalents of all Obligations
on the Senior Debt; that the subordination is for the benefit
of, and shall be enforceable directly by, the holders of Senior
Debt, and that each holder of Senior Debt whether now
outstanding or hereafter created, incurred, assumed or
guaranteed shall be deemed to have acquired Senior Debt in
reliance upon the covenants and provisions contained in this
Indenture and the Notes.

            SECTION 10.02.  No Payment on Notes in
                            Certain Circumstances.
                            ----------------------

            (a)   If any default occurs and is continuing in the
payment when due, whether at maturity, upon redemption, by
declaration or otherwise, of any principal of, interest on,
unpaid drawings for letters of credit issued in respect of, or

 
                                      -98-

regularly accruing fees with respect to, any Senior Debt, no
payment of any kind or character shall be made by, or on behalf
of, the Company or any other Person on its or their behalf with
respect to any Obligations on the Notes, or to acquire any of
the Notes for cash or property or otherwise.  In addition, if
any other event of default occurs and is continuing with
respect to any Designated Senior Debt, as such event of default
is defined in the instrument creating or evidencing such
Designated Senior Debt, permitting the holders of such
Designated Senior Debt then outstanding to accelerate the
maturity thereof and if the Representative for the respective
issue of Designated Senior Debt gives notice of the event of
default to the Trustee (a "Default Notice"), then, unless and
until all events of default have been cured or waived or have
ceased to exist or the Trustee receives notice thereof from the
Representative for the respective issue of Designated Senior
Debt terminating the Blockage Period (as defined below), during
the 180 days after the delivery of such Default Notice (the
"Blockage Period"), neither the Company nor any other Person on
its behalf shall (x) make any payment of any kind or character
with respect to any Obligations on the Notes or (y) acquire any
of the Notes for cash or property or otherwise.
Notwithstanding anything herein to the contrary, in no event
will a Blockage Period extend beyond 180 days from the date the
payment on the Notes was due and only one such Blockage Period
may be commenced within any 360 consecutive days.  No event of
default which existed or was continuing on the date of the
commencement of any Blockage Period with respect to the
Designated Senior Debt shall be, or be made, the basis for the
commencement of a second Blockage Period by the Representative
of such Designated Senior Debt whether or not within a period
of 360 consecutive days, unless such event of default shall
have been cured or waived for a period of not less than 90
consecutive days (it being acknowledged that any subsequent
action, or any breach of any financial covenants for a period
commencing after the date of commencement of such Blockage
Period that, in either case, would give rise to an event of
default pursuant to any provisions under which an event of
default previously existed or was continuing shall constitute a
new event of default for this purpose).

            (b)   In the event that, notwithstanding the
foregoing, any payment shall be received by the Trustee or any
Holder when such payment is prohibited by Section 10.02(a),
such payment shall be held in trust for the benefit of, and
shall be paid over or delivered to, the holders of Senior Debt
(pro rata to such holders on the basis of the respective amount

 
                                      -99-

of Senior Debt held by such holders) or their respective
Representatives, as their respective interests may appear.  The
Trustee shall be entitled to rely on information regarding
amounts then due and owing on the Senior Debt, if any, received
from the holders of Senior Debt (or their Representatives) or,
if such information is not received from such holders or their
Representatives, from the Company and only amounts included in
the information provided to the Trustee shall be paid to the
holders of Senior Debt.

            Nothing contained in this Article Ten shall limit the
right of the Trustee or the Holders of Notes to take any action
to accelerate the maturity of the Notes pursuant to
Section 6.02 or to pursue any rights or remedies hereunder;
provided that all Senior Debt thereafter due or declared to be
- --------
due shall first be paid in full in cash or Cash Equivalents
before the Holders are entitled to receive any payment of any
kind or character with respect to Obligations on the Notes.

            SECTION 10.03.  Payment Over of Proceeds
                            upon Dissolution, Etc.  
                            ------------------------

            (a)   Upon any payment or distribution of assets of
the Company of any kind or character, whether in cash, property
or securities, to creditors upon any total or partial
liquidation, dissolution, winding-up, reorganization,
assignment for the benefit of creditors or marshaling of assets
of the Company or in a bankruptcy, reorganization, insolvency,
receivership or other similar proceeding relating to the
Company or its property, whether voluntary or involuntary, all
Obligations due or to become due upon all Senior Debt shall
first be paid in full in cash or Cash Equivalents, or such
payment duly provided for to the satisfaction of the holders of
Senior Debt, before any payment or distribution of any kind or
character is made on account of any Obligations on the Notes,
or for the acquisition of any of the Notes for cash or property
or otherwise.  Upon any such dissolution, winding-up,
liquidation, reorganization, receivership or similar
proceeding, any payment or distribution of assets of the
Company of any kind or character, whether in cash, property or
securities, to which the Holders of the Notes or the Trustee
under this Indenture would be entitled, except for the
provisions hereof, shall be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or
other Person making such payment or distribution, or by the
Holders or by the Trustee under this Indenture if received by
them, directly to the holders of Senior Debt (pro rata to such
holders on the basis of the respective amounts of Senior Debt

 
                                     -100-

held by such holders) or their respective Representatives, or
to the trustee or trustees under any indenture pursuant to
which any of such Senior Debt may have been issued, as their
respective interests may appear, for application to the payment
of Senior Debt remaining unpaid until all such Senior Debt has
been paid in full in cash or Cash Equivalents after giving
effect to any concurrent payment, distribution or provision
therefor to or for the holders of Senior Debt.

            (b)   To the extent any payment of Senior Debt
(whether by or on behalf of the Company, as proceeds of
security or enforcement of any right of setoff or otherwise) is
declared to be fraudulent or preferential, set aside or
required to be paid to any receiver, trustee in bankruptcy,
liquidating trustee, agent or other similar Person under any
bankruptcy, insolvency, receivership, fraudulent conveyance or
similar law, then, if such payment is recovered by, or paid
over to, such receiver, trustee in bankruptcy, liquidating
trustee, agent or other similar Person, the Senior Debt or part
thereof originally intended to be satisfied shall be deemed to
be reinstated and outstanding as if such payment had not
occurred.

            (c)   In the event that, notwithstanding the
foregoing, any payment or distribution of assets of the Company
of any kind or character, whether in cash, property or
securities, shall be received by any Holder when such payment
or distribution is prohibited by Section 10.03(a), such payment
or distribution shall be held in trust for the benefit of, and
shall be paid over or delivered to, the holders of Senior Debt
(pro rata to such holders on the basis of the respective amount
of Senior Debt held by such holders) or their respective
Representatives, or to the trustee or trustees under any
indenture pursuant to which any of such Senior Debt may have
been issued, as their respective interests may appear, for
application to the payment of Senior Debt remaining unpaid
until all such Senior Debt has been paid in full in cash or
Cash Equivalents, after giving effect to any concurrent
payment, distribution or provision therefor to or for the
holders of such Senior Debt.

            (d)   The consolidation of the Company with, or the
merger of the Company with or into, another corporation or the
liquidation or dissolution of the Company following the
conveyance or transfer of all or substantially all of its
assets, to another corporation upon the terms and conditions
provided in Article Five hereof and as long as permitted under
the terms of the Senior Debt shall not be deemed a dissolution,
winding-up, 

 
                                     -101-

liquidation or reorganization for the purposes of
this Section if such other corporation shall, as a part of such
consolidation, merger, conveyance or transfer, assume the
Company's obligations hereunder in accordance with Article Five
hereof.

            SECTION 10.04.  Payments May Be Paid Prior
                            to Dissolution.
                            --------------------------

            Nothing contained in this Article Ten or elsewhere in
this Indenture shall prevent (i) the Company, except under the 
conditions described in Sections 10.02 and 10.03, from making
payments at any time for the purpose of making payments of
principal of and interest on the Notes, or from depositing with
the Trustee any moneys for such payments, or (ii) in the
absence of actual knowledge by the Trustee that a given payment
would be prohibited by Section 10.02 or 10.03, the application
by the Trustee of any moneys deposited with it for the purpose
of making such payments of principal of, and interest on, the
Notes to the Holders entitled thereto unless at least two
Business Days prior to the date upon which such payment would
otherwise become due and payable a Trust Officer shall have
actually received the written notice provided for in the second
sentence of Section 10.02(a) or in Section 10.07 (provided
                                                  --------
that, notwithstanding the foregoing, such application shall
otherwise be subject to the provisions of the first sentence of
Section 10.02(a) and Section 10.03).  The Company shall give
prompt written notice to the Trustee of any dissolution,
winding-up, liquidation or reorganization of the Company.

            SECTION 10.05.  Subrogation.
                            -----------

            Subject to the payment in full in cash or Cash
Equivalents of all Senior Debt, the Holders of the Notes shall
be subrogated to the rights of the holders of Senior Debt to
receive payments or distributions of cash, property or
securities of the Company applicable to the Senior Debt until
the Notes shall be paid in full; and, for the purposes of such
subrogation, no such payments or distributions to the holders
of the Senior Debt by or on behalf of the Company or by or on
behalf of the Holders by virtue of this Article Ten which
otherwise would have been made to the Holders shall, as between
the Company and the Holders of the Notes, be deemed to be a
payment by the Company to or on account of the Senior Debt, it
being understood that the provisions of this Article Ten are
and are intended solely for the purpose of defining the
relative rights of the Holders of the Notes, on the one hand,
and the holders of the Senior Debt, on the other hand.

            SECTION 10.06.  Obligations of the Company
                            Unconditional.
                            --------------------------

            Nothing contained in this Article Ten or elsewhere in
this Indenture or in the Notes is intended to or shall impair,
as among the Company, its creditors other than the holders of
Senior Debt, and the Holders, the obligation of the Company,
which is absolute and unconditional, to pay to the Holders the
principal of and any interest on the Notes as and when the same
shall become due and payable in accordance with their terms, or
is intended to or shall affect the relative rights of the
Holders and creditors of the Company other than the holders of
the Senior Debt, nor shall anything herein or therein prevent
the Holder of any Note or the Trustee on its behalf from
exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if
any, in respect of cash, property or securities of the Company
received upon the exercise of any such remedy.

            SECTION 10.07.  Notice to Trustee.
                            -----------------

            The Company shall give prompt written notice to the
Trustee of any fact known to the Company which would prohibit
the making of any payment to or by the Trustee in respect of
the Notes pursuant to the provisions of this Article Ten.
Regardless of anything to the contrary contained in this
Article Ten or elsewhere in this Indenture, the Trustee shall
not be charged with knowledge of the existence of any default
or event of default with respect to any Senior Debt or of any
other facts which would prohibit the making of any payment to
or by the Trustee unless and until the Trustee shall have
received notice in writing from the Company, or from a holder
of Senior Debt or a Representative therefor, together with
proof satisfactory to the Trustee of such holding of Senior
Debt or of the authority of such Representative, and, prior to
the receipt of any such written notice, the Trustee shall be
entitled to assume (in the absence of actual knowledge to the
contrary) that no such facts exist.

            In the event that the Trustee determines in good
faith that any evidence is required with respect to the right
of any Person as a holder of Senior Debt to participate in any
payment or distribution pursuant to this Article Ten, the
Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amounts of
Senior Debt held by such Person, the extent to which such
Person is entitled to participate in such payment or distribu-
tion and any 

 
                                     -103-

other facts pertinent to the rights of such Person
under this Article Ten, and if such evidence is not furnished
the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to
receive such payment.

            SECTION 10.08.  Reliance on Judicial Order or
                            Certificate of Liquidating Agent.
                            --------------------------------

            Upon any payment or distribution of assets of the
Company referred to in this Article Ten, the Trustee, subject
to the provisions of Article Seven hereof, and the Holders of
the Notes shall be entitled to rely upon any order or decree
made by any court of competent jurisdiction in which any
insolvency, bankruptcy, receivership, dissolution, winding-up,
liquidation, reorganization or similar case or proceeding is
pending, or upon a certificate of the receiver, trustee in
bankruptcy, liquidating trustee, receiver, assignee for the
benefit of creditors, agent or other person making such payment
or distribution, delivered to the Trustee or the Holders of the
Notes, for the purpose of ascertaining the persons entitled to
participate in such payment or distribution, the holders of the
Senior Debt and other Indebtedness of the Company, the amount
thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to
this Article Ten.

            SECTION 10.09.  Trustee's Relation to Senior Debt.
                            ---------------------------------

            The Trustee and any agent of the Company or the
Trustee shall be entitled to all the rights set forth in this
Article Ten with respect to any Senior Debt which may at any
time be held by it in its individual or any other capacity to
the same extent as any other holder of Senior Debt and nothing
in this Indenture shall deprive the Trustee or any such agent
of any of its rights as such holder.

            With respect to the holders of Senior Debt, the
Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this
Article Ten, and no implied covenants or obligations with
respect to the holders of Senior Debt shall be read into this
Indenture against the Trustee.  The Trustee shall not be deemed
to owe any fiduciary duty to the holders of Senior Debt.

            Whenever a distribution is to be made or a notice
given to holders or owners of Senior Debt, the distribution may

 
                                     -104-

be made and the notice may be given to their Representative, if
any.

            SECTION 10.10.  Subordination Rights Not Impaired
                            by Acts or Omissions of the Company
                            or Holders of Senior Debt.         
                            -----------------------------------

            No right of any present or future holders of any
Senior Debt to enforce subordination as provided herein shall
at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or
failure to act, in good faith, by any such holder, or by any
noncompliance by the Company with the terms of this Indenture,
regardless of any knowledge thereof which any such holder may
have or otherwise be charged with.

            Without in any way limiting the generality of the
foregoing paragraph, the holders of Senior Debt may, at any
time and from time to time, without the consent of or notice to
the Trustee, without incurring responsibility to the Trustee or
the Holders of the Notes and without impairing or releasing the
subordination provided in this Article Ten or the obligations
hereunder of the Holders of the Notes to the holders of the
Senior Debt, do any one or more of the following:  (i) change
the manner, place or terms of payment or extend the time of
payment of, or renew or alter, Senior Debt, or otherwise amend
or supplement in any manner Senior Debt, or any instrument
evidencing the same or any agreement under which Senior Debt is
outstanding; (ii) sell, exchange, release or otherwise deal
with any property pledged, mortgaged or otherwise securing
Senior Debt; (iii) release any Person liable in any manner for
the payment or collection of Senior Debt; and (iv) exercise or
refrain from exercising any rights against the Company and any
other Person.

            SECTION 10.11.  Noteholders Authorize Trustee To
                            Effectuate Subordination of Notes.
                            ---------------------------------

            Each Holder of Notes by its acceptance of them
authorizes and expressly directs the Trustee on its behalf to
take such action as may be necessary or appropriate to
effectuate, as between the holders of Senior Debt and the
Holders of Notes, the subordination provided in this Article
Ten, and appoints the Trustee its attorney-in-fact for such
purposes, including, in the event of any dissolution,
winding-up, liquidation or reorganization of the Company
(whether in bankruptcy, insolvency, receivership,
reorganization or similar proceedings or 

 
                                     -105-

upon an assignment for the benefit of creditors or otherwise)
tending towards liquidation of the business and assets of the
Company, the filing of a claim for the unpaid balance of its
Notes and accrued interest in the form required in those
proceedings.

            If the Trustee does not file a proper claim or proof
of debt in the form required in such proceeding prior to 30
days before the expiration of the time to file such claim or
claims, then the holders of the Senior Debt or their
Representative are or is hereby authorized to have the right to
file and are or is hereby authorized to file an appropriate
claim for and on behalf of the Holders of said Notes.  Nothing
herein contained shall be deemed to authorize the Trustee or
the holders of Senior Debt or their Representative to authorize
or consent to or accept or adopt on behalf of any Holder any
plan of reorganization, arrangement, adjustment or composition
affecting the Notes or the rights of any Holder thereof, or to
authorize the Trustee or the holders of Senior Debt or their
Representative to vote in respect of the claim of any Holder in
any such proceeding.

            SECTION 10.12.  This Article Ten Not To
                            Prevent Events of Default.
                            -------------------------
 
            The failure to make a payment on account of principal
of or interest on the Notes by reason of any provision of this
Article Ten will not be construed as preventing the occurrence
of an Event of Default.

            SECTION 10.13.  Trustee's Compensation
                            Not Prejudiced.       
                            ----------------------

            Nothing in this Article Ten will apply to amounts due
to the Trustee pursuant to other sections in this Indenture.

                 11 1/8% SENIOR SUBORDINATED NOTE DUE 2006

            1.    Interest.  DADE INTERNATIONAL INC., a Delaware
                  --------
corporation (the "Company"), promises to pay interest on the
principal amount of this Note at the rate per annum shown
above.  Interest on the Notes will accrue from the most recent
date on which interest has been paid or, if no interest has
been paid, from May 7, 1996.  The Company will pay interest
semi-annually in arrears on each Interest Payment Date,
commencing November 1, 1996.  Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

            The Company shall pay interest on overdue principal
and on overdue installments of interest from time to time on
demand at the rate borne by the Notes plus 2% per annum and on
overdue installments of interest (without regard to any
applicable grace periods) to the extent lawful.  

            2.    Method of Payment.  The Company shall pay
                  -----------------
interest on the Notes (except defaulted interest) to the
Persons who are the registered Holders at the close of business
on the Record Date immediately preceding the Interest Payment
Date even if the Notes are cancelled on registration of
transfer or registration of exchange after such Record Date.
Holders must surrender Notes to a Paying Agent to collect
principal payments.  The Company shall pay principal and
interest in money of the United States that at the time of
payment is legal tender for payment of public and private debts
("U.S. Legal Tender").  However, the Company may pay principal
and interest by its check payable in such U.S. Legal Tender.
The Company may deliver any such interest payment to the Paying
Agent or to a Holder at the Holder's registered address.

            3.    Paying Agent and Registrar.  Initially, IBJ
                  --------------------------
Schroder Bank & Trust Company, a New York banking corporation
(the "Trustee"), will act as Paying Agent and Registrar.  The
Company may change any Paying Agent, Registrar or co-Registrar
without notice to the Holders.

            4.    Indenture.  The Company issued the Notes under
                  ---------
an Indenture, dated as of May 7, 1996 (the "Indenture"),
between the Company and the Trustee.  This Note is one of a
duly authorized issue of Initial Notes of the Company
designated as its 11 1/8% Senior Subordinated Notes due 2006
(the "Initial Notes").  The Notes are limited in aggregate
principal amount to $350,000,000.  The Notes include the
Initial Notes and the Exchange Notes, as defined below, issued
in exchange 

                                    A-2
 

 
for the Initial Notes pursuant to the Indenture. The Initial
Notes and the Exchange Notes are treated as a single class of
securities under the Indenture. Capitalized terms herein are
used as defined in the Indenture unless otherwise defined
herein. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939 (15 U.S. Code {{ 77aaa-77bbbb)
(the "TIA"), as in effect on the date of the Indenture.
Notwithstanding anything to the contrary herein, the Notes are
subject to all such terms, and Holders of Notes are referred to
the Indenture and said Act for a statement of them. The Notes
are general unsecured obligations of the Company.

            5.    Subordination.  The Notes are subordinated in
                  -------------
right of payment, in the manner and to the extent set forth in
the Indenture, to the prior payment in full in cash or Cash
Equivalents of all Senior Debt of the Company, whether
outstanding on the date of the Indenture or thereafter created,
incurred, assumed or guaranteed.  Each Holder by his acceptance
hereof agrees to be bound by such provisions and authorizes and
expressly directs the Trustee, on his behalf, to take such
action as may be necessary or appropriate to effectuate the
subordination provided for in the Indenture and appoints the
Trustee his attorney-in-fact for such purposes.

            6.    Redemption.
                  ----------

            (a)   Optional Redemption. The Notes will be
                  -------------------

part from time to time, on and after May 1, 2001, upon not less

redemption prices (expressed as percentages of the principal
amount thereof) if redeemed during the twelve-month period
commencing on May 1 of the year set forth below, plus, in each
case, accrued interest to the date of redemption:

            (b)   Optional Redemption Upon Equity Offerings. At
                  -----------------------------------------
any time, or from time to time, on or prior to May 1, 1999, the
Company may, at its option, use the net cash proceeds of one or
more Equity Offerings (as defined in the Indenture) to redeem
up to 40% (provided that such percentage shall decrease to 35%
if an Initial Public Offering (as defined in the Indenture) has
not been consummated on or prior to March 31, 1997 and any


                                    A-3
 

 
other Notes previously redeemed pursuant to this provision
shall be included in determining such percentage) of the
aggregate principal amount of Notes originally issued at a
redemption price equal to 110% (111.125% in the case of any
Equity Offering after March 31, 1997) of the principal amount
thereof plus, in each case, accrued interest to the date of
redemption; provided that at least $175.0 million aggregate
            --------
principal amount of Notes remains outstanding immediately after
any such redemption.

            In order to effect the foregoing redemption with the
proceeds of any Equity Offering, the Company shall make such
redemption not more than 120 days after the consummation of any
such Equity Offering.

            7.    Notice of Redemption.  Notice of redemption will
                  --------------------
be mailed at least 30 days but not more than 60 days before the
Redemption Date to each Holder of Notes to be redeemed at such
Holder's registered address.  Notes in denominations larger
than $1,000 may be redeemed in part.

            Except as set forth in the Indenture, if monies for
the redemption of the Notes called for redemption shall have
been deposited with the Paying Agent for redemption on such
Redemption Date, then, unless the Company defaults in the
payment of such Redemption Price plus accrued interest, if any,
the Notes called for redemption will cease to bear interest
from and after such Redemption Date and the only right of the
Holders of such Notes will be to receive payment of the
Redemption Price plus accrued interest, if any.

            8.    Offers to Purchase.  Sections 4.15 and 4.16 of
                  ------------------
the Indenture provide that, after certain Asset Sales (as
defined in the Indenture) and upon the occurrence of a Change
of Control (as defined in the Indenture), and subject to
further limitations contained therein, the Company will make an
offer to purchase certain amounts of the Notes in accordance
with the procedures set forth in the Indenture.

            9.    Registration Rights.  Pursuant to the
                  -------------------
Registration Rights Agreement among the Company and the Holders
of the Initial Notes, the Company will be obligated to
consummate an exchange offer pursuant to which the Holder of
this Note shall have the right to exchange this Note for the
Company's Series B 11 1/8% Senior Subordinated Notes due 2006
(the "Exchange Notes"), which have been registered under the
Securities Act, in like principal amount and having terms
identical in all material respects to the Initial Notes.  The
Holders of the Initial Notes shall be entitled to receive
certain additional interest payments in the event such exchange
offer is not 


                                    A-4
 

 
consummated and upon certain other conditions, all pursuant to
and in accordance with the terms of the Registration Rights
Agreement.

            10.   Denominations; Transfer; Exchange.  The Notes
                  ---------------------------------
are in registered form, without coupons, in denominations of
$1,000 and integral multiples of $1,000.  A Holder shall
register the transfer of or exchange Notes in accordance with
the Indenture.  The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer
documents and to pay certain transfer taxes or similar
governmental charges payable in connection therewith as
permitted by the Indenture.  The Registrar need not register
the transfer of or exchange of any Notes or portions thereof
selected for redemption.

            11.   Persons Deemed Owners.  The registered Holder of
                  ---------------------
a Note shall be treated as the owner of it for all purposes.

            12.   Unclaimed Money.  If money for the payment of
                  ---------------
principal or interest remains unclaimed for two years, the
Trustee and the Paying Agent will pay the money back to the
Company.  After that, all liability of the Trustee and such
Paying Agent with respect to such money shall cease.

            13.   Discharge Prior to Redemption or Maturity.  If
                  -----------------------------------------
the Company at any time deposits with the Trustee U.S. Legal
Tender or U.S. Government Obligations sufficient to pay the
principal of and interest on the Notes to redemption or
maturity and complies with the other provisions of the
Indenture relating thereto, the Company will be discharged from
certain provisions of the Indenture and the Notes (including
certain covenants, but excluding its obligation to pay the
principal of and interest on the Notes).

            14.   Amendment; Supplement; Waiver.  Subject to
                  -----------------------------
certain exceptions, the Indenture or the Notes may be amended
or supplemented with the written consent of the Holders of at
least a majority in aggregate principal amount of the Notes
then outstanding, and any existing Default or Event of Default
or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in aggregate
principal amount of the Notes then outstanding.  Without notice
to or consent of any Holder, the parties thereto may amend or
supplement the Indenture or the Notes to, among other things,
cure any ambiguity, defect or inconsistency, provide for
uncertificated Notes in addition to or in place of certificated
Notes, or comply with Article Five of the Indenture or make any
other change that does not adversely affect in any material
respect the rights of any Holder of a Note.


                                    A-5
 

 
            15.   Restrictive Covenants.  The Indenture imposes
                  ---------------------
certain limitations on the ability of the Company and its
Restricted Subsidiaries to, among other things, incur
additional Indebtedness, make payments in respect of its
Capital Stock or certain Indebtedness, enter into transactions
with Affiliates, create dividend or other payment restrictions
affecting Subsidiaries, merge or consolidate with any other
Person, sell, assign, transfer, lease, convey or otherwise
dispose of all or substantially all of its assets or adopt a
plan of liquidation.  Such limitations are subject to a number
of important qualifications and exceptions.  The Company must
annually report to the Trustee on compliance with such
limitations.

            16.   Successors.  When a successor assumes, in
                  ----------
accordance with the Indenture, all the obligations of its
predecessor under the Notes and the Indenture, the predecessor
will be released from those obligations.

            17.   Defaults and Remedies.  If an Event of Default
                  ---------------------
occurs and is continuing, the Trustee or the Holders of at
least 25% in aggregate principal amount of Notes then
outstanding may declare all the Notes to be due and payable in
the manner, at the time and with the effect provided in the
Indenture.  Holders of Notes may not enforce the Indenture or
the Notes except as provided in the Indenture.  The Trustee is
not obligated to enforce the Indenture or the Notes unless it
has received indemnity reasonably satisfactory to it.  The
Indenture permits, subject to certain limitations therein
provided, Holders of a majority in aggregate principal amount
of the Notes then outstanding to direct the Trustee in its
exercise of any trust or power.  The Trustee may withhold from
Holders of Notes notice of any continuing Default or Event of
Default (except a Default in payment of principal or interest)
if it determines that withholding notice is in their interest.

            18.   Trustee Dealings with Company.  The Trustee
                  -----------------------------
under the Indenture, in its individual or any other capacity,
may become the owner or pledgee of Notes and may otherwise deal
with the Company, its Subsidiaries or their respective
Affiliates as if it were not the Trustee.

            19.   No Recourse Against Others.  No stockholder,
                  --------------------------
director, officer, employee or incorporator, as such, of the
Company shall have any liability for any obligation of the
Company under the Notes or the Indenture or for any claim based
on, in respect of or by reason of, such obligations or their
creation.  Each Holder of a Note by accepting a Note waives and
releases all such liability.  The waiver and release are part
of the consideration for the issuance of the Notes.



                                    A-6
 

 
            20.   Authentication.  This Note shall not be valid
                  --------------
until the Trustee or Authenticating Agent manually signs the
certificate of authentication on this Note.

            21.   Governing Law.  The Laws of the State of New
                  -------------
York shall govern this Note and the Indenture, without regard
to principles of conflict of laws.

            22.   Abbreviations and Defined Terms.  Customary

            SERIES B 11 1/8% SENIOR SUBORDINATED NOTE DUE 2006

            1.    Interest.  DADE INTERNATIONAL INC., a Delaware
                  --------
corporation (the "Company"), promises to pay interest on the
principal amount of this Note at the rate per annum shown
above.  Interest on the Notes will accrue from the most recent
date on which interest has been paid or, if no interest has
been paid, from May 7, 1996.  The Company will pay interest
semi-annually in arrears on each Interest Payment Date,
commencing November 1, 1996.  Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

            The Company shall pay interest on overdue principal
and on overdue installments of interest from time to time on
demand at the rate borne by the Notes plus 2% per annum and on
overdue installments of interest (without regard to any
applicable grace periods) to the extent lawful.  

            2.    Method of Payment.  The Company shall pay
                  -----------------
interest on the Notes (except defaulted interest) to the
Persons who are the registered Holders at the close of business
on the Record Date immediately preceding the Interest Payment
Date even if the Notes are cancelled on registration of
transfer or registration of exchange after such Record Date.
Holders must surrender Notes to a Paying Agent to collect
principal payments.  The Company shall pay principal and
interest in money of the United States that at the time of
payment is legal tender for payment of public and private debts
("U.S. Legal Tender").  However, the Company may pay principal
and interest by its check payable in such U.S. Legal Tender.
The Company may deliver any such interest payment to the Paying
Agent or to a Holder at the Holder's registered address.

            3.    Paying Agent and Registrar.  Initially, IBJ
                  --------------------------
Schroder Bank & Trust Company, a New York banking corporation
(the "Trustee"), will act as Paying Agent and Registrar.  The
Company may change any Paying Agent, Registrar or co-Registrar
without notice to the Holders.

            4.    Indenture.  The Company issued the Notes under
                  ---------
an Indenture, dated as of May 7, 1996 (the "Indenture"),
between the Company and the Trustee.  This Note is one of a
duly authorized issue of Exchange Notes of the Company
designated as its Series B 11 1/8% Senior Subordinated Notes
due 2006 (the "Exchange Notes").  The Notes are limited in
aggregate principal amount to $350,000,000.  The Notes include
the Initial Notes (the 11 1/8% Senior Subordinated Notes due
2006) 

                                    B-2
 

 
and the Exchange Notes, issued in exchange for the
Initial Notes pursuant to the Indenture.  The Initial Notes and
the Exchange Notes are treated as a single class of securities
under the Indenture.  Capitalized terms herein are used as
defined in the Indenture unless otherwise defined herein.  The
terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S. Code {{ 77aaa-77bbbb) (the
"TIA"), as in effect on the date of the Indenture.
Notwithstanding anything to the contrary herein, the Notes are
subject to all such terms, and Holders of Notes are referred to
the Indenture and said Act for a statement of them.  The Notes
are general unsecured obligations of the Company.

            5.    Subordination.  The Notes are subordinated in
                  -------------
right of payment, in the manner and to the extent set forth in
the Indenture, to the prior payment in full in cash or Cash
Equivalents of all Senior Debt of the Company, whether
outstanding on the date of the Indenture or thereafter created,
incurred, assumed or guaranteed.  Each Holder by his acceptance
hereof agrees to be bound by such provisions and authorizes and
expressly directs the Trustee, on his behalf, to take such
action as may be necessary or appropriate to effectuate the
subordination provided for in the Indenture and appoints the
Trustee his attorney-in-fact for such purposes.

            6.    Redemption.
                  ----------

            (a)   Optional Redemption. The Notes will be
                  -------------------
redeemable, at the Company's option, in whole at any time or in
part from time to time, on and after May 1, 2001, upon not less
than 30 nor more than 60 days' notice, at the following
redemption prices (expressed as percentages of the principal
amount thereof) if redeemed during the twelve-month period
commencing on May 1 of the year set forth below, plus, in each
case, accrued interest to the date of redemption:

Year                                                      Percentage
- ----                                                      ----------

2001.....................................................  105.563%
2002.....................................................  103.708
2003.....................................................  101.854
2004 and thereafter......................................  100.000

            (b)   Optional Redemption Upon Equity Offerings. At
                  -----------------------------------------
any time, or from time to time, on or prior to May 1, 1999, the
Company may, at its option, use the net cash proceeds of one or
more Equity Offerings (as defined in the Indenture) to redeem
up to 40% (provided that such percentage shall decrease to 35%
if an Initial Public Offering (as defined in the Indenture) has


                                    B-3
 

 
not been consummated on or prior to March 31, 1997 and any
other Notes previously redeemed pursuant to this provision
shall be included in determining such percentage) of the
aggregate principal amount of Notes originally issued at a
redemption price equal to 110% (111.125% in the case of any
Equity Offering after March 31, 1997) of the principal amount
thereof plus, in each case, accrued interest to the date of
redemption; provided that at least $175.0 million aggregate
            --------
principal amount of Notes remains outstanding immediately after
any such redemption.

            In order to effect the foregoing redemption with the
proceeds of any Equity Offering, the Company shall make such
redemption not more than 120 days after the consummation of any
such Equity Offering.

            7.    Notice of Redemption.  Notice of redemption will
                  --------------------
be mailed at least 30 days but not more than 60 days before the
Redemption Date to each Holder of Notes to be redeemed at such
Holder's registered address.  Notes in denominations larger
than $1,000 may be redeemed in part.

            Except as set forth in the Indenture, if monies for
the redemption of the Notes called for redemption shall have
been deposited with the Paying Agent for redemption on such
Redemption Date, then, unless the Company defaults in the
payment of such Redemption Price plus accrued interest, if any,
the Notes called for redemption will cease to bear interest
from and after such Redemption Date and the only right of the
Holders of such Notes will be to receive payment of the
Redemption Price plus accrued interest, if any.

            8.    Offers to Purchase.  Sections 4.15 and 4.16 of
                  ------------------
the Indenture provide that, after certain Asset Sales (as
defined in the Indenture) and upon the occurrence of a Change
of Control (as defined in the Indenture), and subject to
further limitations contained therein, the Company will make an
offer to purchase certain amounts of the Notes in accordance
with the procedures set forth in the Indenture.

            9.    Denominations; Transfer; Exchange.  The Notes
                  ---------------------------------
are in registered form, without coupons, in denominations of
$1,000 and integral multiples of $1,000.  A Holder shall
register the transfer of or exchange Notes in accordance with
the Indenture.  The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer
documents and to pay certain transfer taxes or similar
governmental charges payable in connection therewith as
permitted by the Indenture.  The Registrar need not register
the transfer of or 

                                    B-4
 

 
exchange of any Notes or portions thereof
selected for redemption.

            10.   Persons Deemed Owners.  The registered Holder of
                  ---------------------
a Note shall be treated as the owner of it for all purposes.

            11.   Unclaimed Money.  If money for the payment of
                  ---------------
principal or interest remains unclaimed for two years, the
Trustee and the Paying Agent will pay the money back to the
Company.  After that, all liability of the Trustee and such
Paying Agent with respect to such money shall cease.

            12.   Discharge Prior to Redemption or Maturity.  If
                  -----------------------------------------
the Company at any time deposits with the Trustee U.S. Legal
Tender or U.S. Government Obligations sufficient to pay the
principal of and interest on the Notes to redemption or
maturity and complies with the other provisions of the
Indenture relating thereto, the Company will be discharged from
certain provisions of the Indenture and the Notes (including
certain covenants, but excluding its obligation to pay the
principal of and interest on the Notes).

            13.   Amendment; Supplement; Waiver.  Subject to
                  -----------------------------
certain exceptions, the Indenture or the Notes may be amended
or supplemented with the written consent of the Holders of at
least a majority in aggregate principal amount of the Notes
then outstanding, and any existing Default or Event of Default
or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in aggregate
principal amount of the Notes then outstanding.  Without notice
to or consent of any Holder, the parties thereto may amend or
supplement the Indenture or the Notes to, among other things,
cure any ambiguity, defect or inconsistency, provide for
uncertificated Notes in addition to or in place of certificated
Notes, or comply with Article Five of the Indenture or make any
other change that does not adversely affect in any material
respect the rights of any Holder of a Note.

            14.   Restrictive Covenants.  The Indenture imposes
                  ---------------------
certain limitations on the ability of the Company and its
Restricted Subsidiaries to, among other things, incur
additional Indebtedness, make payments in respect of its
Capital Stock or certain Indebtedness, enter into transactions
with Affiliates, create dividend or other payment restrictions
affecting Subsidiaries, merge or consolidate with any other
Person, sell, assign, transfer, lease, convey or otherwise
dispose of all or substantially all of its assets or adopt a
plan of liquidation.  Such limitations are subject to a number
of important qualifications and exceptions.  The Company must


                                    B-5
 

 
annually report to the Trustee on compliance with such
limitations.

            15.   Successors.  When a successor assumes, in
                  ----------
accordance with the Indenture, all the obligations of its
predecessor under the Notes and the Indenture, the predecessor
will be released from those obligations.

            16.   Defaults and Remedies.  If an Event of Default
                  ---------------------
occurs and is continuing, the Trustee or the Holders of at
least 25% in aggregate principal amount of Notes then
outstanding may declare all the Notes to be due and payable in
the manner, at the time and with the effect provided in the
Indenture.  Holders of Notes may not enforce the Indenture or
the Notes except as provided in the Indenture.  The Trustee is
not obligated to enforce the Indenture or the Notes unless it
has received indemnity reasonably satisfactory to it.  The
Indenture permits, subject to certain limitations therein
provided, Holders of a majority in aggregate principal amount
of the Notes then outstanding to direct the Trustee in its
exercise of any trust or power.  The Trustee may withhold from
Holders of Notes notice of any continuing Default or Event of
Default (except a Default in payment of principal or interest)
if it determines that withholding notice is in their interest.

            17.   Trustee Dealings with Company.  The Trustee
                  -----------------------------
under the Indenture, in its individual or any other capacity,
may become the owner or pledgee of Notes and may otherwise deal
with the Company, its Subsidiaries or their respective
Affiliates as if it were not the Trustee.

            18.   No Recourse Against Others.  No stockholder,

                  Subordinated Notes due 2006      
                  ---------------------------------

Ladies and Gentlemen:

            In connection with our proposed purchase of 11 1/8%
Senior Subordinated Notes due 2006 (the "Notes") of Dade
International Inc. (the "Company"), we confirm that:

            1.    We have received a copy of the Offering
Memorandum (the "Offering Memorandum"), dated April 30, 1996
relating to the Notes and such other information as we deem
necessary in order to make our investment decision.  We
acknowledge that we have read and agreed to the matters stated
on pages (i)-(ii) of the Offering Memorandum and in the section
entitled "Transfer Restrictions" of the Offering Memorandum,
including the restrictions on duplication and circulation of
the Offering Memorandum.

            2.    We understand that any subsequent transfer of
the Notes is subject to certain restrictions and conditions set
forth in the Indenture relating to the Notes (as described in
the Offering Memorandum) and the undersigned agrees to be bound
by, and not to resell, pledge or otherwise transfer the Notes
except in compliance with, such restrictions and conditions and
the Securities Act of 1933, as amended (the "Securities Act").

            3.    We understand that the offer and sale of the
Notes have not been registered under the Securities Act, and
that the Notes may not be offered or sold except as permitted
in the following sentence.  We agree, on our own behalf and on
behalf of any accounts for which we are acting as hereinafter
stated, that if we should sell or otherwise transfer any Notes
prior to the date which is three years after the original
issuance of the Notes, we will do so only (i) to the Company or
any of its subsidiaries, (ii) inside the United States in


                                    C-1
 

 
accordance with Rule 144A under the Securities Act to a
"qualified institutional buyer" (as defined in Rule 144A under
the Securities Act), (iii) inside the United States to an
institutional "accredited investor" (as defined below) that,
prior to such transfer, furnishes (or has furnished on its
behalf by a U.S. broker-dealer) to the Trustee (as defined in
the Indenture relating to the Notes), a signed letter
containing certain representations and agreements relating to
the restrictions on transfer of the Notes, (iv) outside the
United States in accordance with Rule 904 of Regulation S under
the Securities Act, (v) pursuant to the exemption from
registration provided by Rule 144 under the Securities Act (if
available), or (vi) pursuant to an effective registration
statement under the Securities Act, and we further agree to
provide to any person purchasing any of the Notes from us a
notice advising such purchaser that resales of the Notes are
restricted as stated herein.

            4.    We are not acquiring the Notes for or on behalf
of, and will not transfer the Notes to, any pension or welfare
plan (as defined in Section 3 of the Employee Retirement Income
Security Act of 1974), except as permitted in the section
entitled "Transfer Restrictions" of the Offering Memorandum.

            5.    We understand that, on any proposed resale of
any Notes, we will be required to furnish to the Trustee and
the Company such certification, legal opinions and other
information as the Trustee and the Company may reasonably
require to confirm that the proposed sale complies with the
foregoing restrictions.  We further understand that the Notes
purchased by us will bear a legend to the foregoing effect.

            6.    We are an institutional "accredited investor"
(as defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D
under the Securities Act) and have such knowledge and
experience in financial and business matters as to be capable
of evaluating the merits and risks of our investment in the
Notes, and we and any accounts for which we are acting are each
able to bear the economic risk of our or their investment, as
the case may be.

            7.    We are acquiring the Notes purchased by us for
our account or for one or more accounts (each of which is an
institutional "accredited investor") as to each of which we
exercise sole investment discretion.
