entirety and in its place shall be substituted the following:

                  (a) Revolving Credit Loans. Subject to the terms and
         conditions hereof, during the Term of this Agreement, Bank hereby
         agrees to make such loans (individually, a "Loan" and collectively, the
         "Loans") to Borrowers, jointly and severally, as any of the Borrowers
         may from time to time request pursuant to Section 3.2 and in Bank's
         discretion, to issue Letters of Credit for the account of the
         Borrowers, or any of them, upon any Borrower's execution of a Letter of
         Credit Application therefor pursuant to Section 3.3 (subject to Bank's

         the Loans available under this Section 3.1, the "Borrowing Base" shall
         mean the sum of:

                           (i) Seventy-Five Percent (75%) of the face amount of
         Eligible  Accounts  of each of the Borrowers, plus

                           (ii) Fifty Percent (50%) of the Eligible Inventory of
         each of the Borrowers; plus

                           (iii) an amount determined by Lender as the loan
         value of Borrowers' fixed assets, which amount shall be deemed to be

         title commitment for Virbac's Tarrant County, Texas real property, (B)
         Bank shall have determined in Bank's sole discretion that such title
         commitment is in form and substance acceptable to Bank and contains no
         liens or other exceptions other than those which are acceptable to
         Bank, and (C) Bank shall have sent notice to Borrowers that Bank shall
         add such Tarrant County, Texas real property's value to the Borrowing
         Base, at which time the amount under this clause (iii) shall be

         10.      Section 3.1(d) of the Loan Agreement shall be deleted in its
entirety and in its place shall be substituted the following:

                  (d) Borrowing Base Certificate. Borrowers shall deliver to
         Bank on the twenty-eighth (28th) day of each month, commencing in the
         month of September, 2003, a borrowing base certificate in the form of
         Exhibit A attached to the Sixth Amendment to Credit Agreement dated as
         of September ___, 2003 made by and among Borrowers and Banks (the
         "Sixth Amendment") and incorporated herein by reference (a "Borrowing
         Base Certificate") setting forth:

                           (i) the Borrowing Base and its components as of the
end of the immediately preceding month;

                           (ii) the aggregate principal amount of all
         outstanding Loans and the aggregate face amount of all issued and
         outstanding Letters of Credit; and

                           (iii) the difference, if any, between the Borrowing
         Base and the aggregate principal amount of all outstanding Loans plus
         the aggregate face amount of all issued and outstanding Letters of
         Credit.

         The Borrowing Base shown in such Borrowing Base Certificate shall be
         and remain the Borrowing Base hereunder until the next Borrowing Base
         Certificate is delivered to Bank, at which time the Borrowing Base
         shall be the amount shown in such subsequent Borrowing Base
         Certificate. Each Borrowing Base Certificate shall be certified
         (subject to normal year-end adjustments) as to truth and accuracy by
         the President, principal financial officer or controller of each of the
         Borrowers.

All references in the Loan Agreement and the other Transaction Documents to the
"Borrowing Base Certificate" and other references of similar import shall
hereafter be amended and deemed to refer to a Borrowing Base Certificate in the
form of the Borrowing Base Certificate, as amended and restated in the form
attached hereto as Exhibit A.

         11. Notwithstanding anything contained herein or in the Loan Agreement,
the Note or any of the other Transaction Documents to the contrary, the
Borrowers' right to request LIBOR Loans under the revolving credit facility and
to convert or continue outstanding Loans as LIBOR Loans is hereby terminated.
The definitions of "Interest Period," "LIBOR Base Rate," "LIBOR Loan," "LIBOR
Margin," "LIBOR Rate," and "LIBOR Reserve Percentage" in Section 2 of the Loan
Agreement shall be of no further effect. All references in the Loan Agreement
and the other Transaction Documents to a LIBOR Loan shall be deleted or shall
hereafter mean a Prime Loan, as the case may require in Bank's determination.
Section 3.2 of the Loan Agreement is hereby deleted in its entirety and in its
place shall be substituted the following:

                           3.2 Procedure for Borrowing. Subject to the terms and
         conditions hereof, Bank shall cause the Loans to be made to Borrowers
         at any time and from time to time during the Term of this Agreement
         upon timely prior oral or written notice ("Borrowing Notice") from any
         of the Borrowers to Bank specifying:

                           (i) the desired amount of the Loan requested;

                           (ii) the date on which the proceeds of any new Loan
         are to be made available to any of the Borrowers, which shall be a
         Business Day;

                           (iii) that on the date of, and after giving effect
         to, such Loan, no Default or Event of Default under this Agreement has
         occurred and is continuing; and

                           (iv) that on the date of, and after giving effect to,
         such Loan, all of the representations and warranties of Borrowers
         contained in this Agreement are true and correct in all material
         respects as if made on the date of such Loan.

         A Borrowing Notice shall not be required in connection with a Prime
         Loan made to cover any overdraft in Virbac's operating account on a
         day-to-day basis as set forth herein. A Borrowing Notice, if in
         writing, shall be in the form of the notice attached as Exhibit B
         hereto. Each Borrowing Notice must be received by Bank not later than
         10:00 a.m. (St. Louis time) on the Business Day on which a Prime Loan
         is to be established. A Borrowing Notice shall not be revocable by
         Borrowers. Subject to the terms and conditions hereof, provided that
         Bank has received the Borrowing Notice, Bank shall (unless Bank
         determines that any applicable condition specified in Section 4 has not
         been satisfied) pay to Borrowers, or any of them, the Loan proceeds of
         any new Loan in immediately available funds not later than 2:00 p.m.
         (St. Louis time) on the Business Day specified in said Borrowing
         Notice. Each of the Borrowers hereby authorizes Bank to reasonably rely
         on telephonic, telegraphic, telecopy, telex or written instructions of
         any person identifying himself as a person authorized to request a Loan
         or make a repayment hereunder, and on any signature which Bank believes
         to be genuine, and Borrowers shall be bound thereby in the same manner
         as if such person were actually authorized or such signature were
         genuine. Borrowers further request and authorize Bank, in Bank's sole
         and absolute discretion, to make a Prime Loan to Borrowers hereunder at
         the end of each day in which Borrowers shall have an overdraft
         (negative ledger balance) in Virbac's operating account (Account No.
         9800801785) with Bank after crediting all deposits received in
         immediately available funds and debiting all withdrawals made and
         checks presented against such account and honored by Bank as of such
         date and after funding any advances to or receiving any collected
         balances on such day from the "zero balance" operating accounts of PM
         Resources (Account No. 9800802535), St. JON (Account No. 9800805419),
         Virbac AH (Account No. 9821908926), and Francodex (Account No.
         9821909433) with Bank to cover withdrawals made and checks presented on
         such date and after crediting all deposits received in immediately
         available funds on such date, which Prime Loan shall be in the amount
         of such overdraft without any other request or authorization therefor
         from Borrowers and without notice to Borrowers. Similarly, Borrowers
         request that Bank apply any collected balances (after funding advances
         to or receiving collections from the "zero balance" accounts of PM
         Resources, St. JON, Virbac AH, and Francodex) in excess of a mutually
         predetermined amount remaining at the end of any day in Virbac's
         operating account to the repayment of the principal balance of
         Borrowers' Obligations outstanding as Prime Loans under the Note.
         Borrowers also hereby agree jointly and severally to indemnify Bank and
         hold Bank harmless from and against any and all claims, demands,
         damages, liabilities, losses, costs and expenses (including, without
         limitation, Attorneys' Fees) relating to or arising out of or in
         connection with the acceptance of instructions for making Loans or
         repayments hereunder. Contemporaneously with the execution of the Sixth
         Amendment (amending this Agreement), Borrowers shall execute and
         deliver to Bank a Note of Borrowers dated as of September ___, 2003 and
         payable jointly and severally to the order of Bank in the original
         principal amount of Thirty Million Dollars ($30,000,000.00) in the form
         attached as Exhibit C to such Sixth Amendment and incorporated herein
         by reference (as the same may from time to time be amended, modified,
         extended or renewed, the "Note").

All references in the Loan Agreement and the other Transaction Documents to a
"Borrowing Notice" and other references of similar import shall hereafter be
amended and deemed to refer to a Borrowing Notice in the form of the Borrowing
Notice, as amended and restated in the form attached hereto as Exhibit B.

         12.      Section 3.3(a)(iv) of the Loan Agreement shall be deleted in
its entirety and in its place shall be substituted the following:

                           (iv) the aggregate undrawn face amount of all
         outstanding Letters of Credit issued hereunder shall not at any one
         time exceed Two Million Dollars ($2,000,000.00); and

         13.      Section 3.4 of the Loan Agreement shall be deleted in its

                  3.4      Interest Rates.

                  (a) Each Loan shall bear interest prior to maturity at a rate
          per annum equal to the Prime Rate plus Floating Rate Margin, each in
          effect from time to time during the period when such Loan is
          outstanding, with changes in the interest rate taking effect on the
          date a change in the Prime Rate is made effective generally by Bank.

                  (b) Blank Intentionally.

                  (c) From and after the maturity of the Note, whether by reason
          of acceleration or otherwise, the entire unpaid principal balance of
          each Loan shall bear interest, payable upon demand, until paid at a
          rate per annum equal to Three and Three-Fourths Percent (3.75%) over
          and above the Prime Rate, fluctuating as aforesaid.

                  (d) Interest shall be computed with respect to all Loans on an
          actual day, 360-day year.

         14.      Section 3.7 of the Loan Agreement shall be deleted in its
entirety and in its place shall be substituted the following:

                           3.7 Place and Manner of Payment. Both principal and
         interest on the Loans are payable to Bank in lawful currency of the
         United States in Federal or other immediately available funds at Bank's
         banking office at 1281 Graham Road, Florissant, Missouri 63031, or at
         such other place as Bank shall designate in writing to Borrowers.
         Borrowers shall make each payment of principal of, and interest on, the
         Loans and of fees and all other amounts payable by Borrowers under this
         Agreement, not later than 2:00 p.m. (St. Louis time) on the date when
         due and payable, in Federal or other funds immediately available in St.
         Louis, Missouri, to the Bank at its address set forth above. All
         payments received by the Bank after 2:00 p.m. (St. Louis time) shall be
         deemed to have been received by the Bank on the next succeeding
         Business Day. Whenever any payment of principal of, or interest on, the
         Loans or of fees shall be due on a day which is not a Business Day, the
         date for payment thereof shall be extended to the next succeeding
         Business Day. If the date for any payment of principal is extended by
         operation of law or otherwise, interest thereon, at the then applicable
         rate, shall be payable for such extended time.

         15.      Section  3.15 of the Loan Agreement shall be deleted in its

         "Commitment Fee") in an amount equal to Three-Eighths of One Percent
         (0.375%) per annum calculated on the basis of the unused Bank's
         Commitment during the preceding fiscal quarter of Borrowers ending as
         of the last day of each January, April, July and October, which unused
         Bank's Commitment shall be arrived at by dividing the aggregate of the
         daily unused Bank's Commitment for each day of that quarter as of the
         close of each day by ninety (90) (or by the actual number of days for
         any partial quarter). Payment of the Commitment Fee is a condition
         precedent to Bank's obligations to make any new Loans hereunder.

         16.      Section 3.16 of the Loan Agreement shall be deleted in its
entirety  and in its place  shall be  substituted  the following:

         Virbac's fiscal year ended at the end of such month, all with
         consolidating disclosures and setting forth in each case in comparative
         form, the figures for the corresponding fiscal month from the previous
         fiscal year and the corresponding portion of Virbac's previous fiscal

         fairness of presentation, Generally Accepted Accounting Principles and

                                        event that the Issuer exercises the
                                        Morgan Stanley Call Right, no Interest

                                        Payment Date; and provided, further,
                                        that accrued but unpaid interest
                                        payable on the Call Date, if any, shall
                                        be payable to the person to whom the
                                        Call Price is payable. The "ex-
                                        interest" date for any interest payment
                                        is the date on which purchase
                                        transactions in the SPARQS no longer
                                        carry the right to receive such
                                        interest payment.

                                        In the event that the Issuer exercises
                                        the Morgan Stanley Call Right and the
                                        Morgan Stanley Notice Date falls before
                                        the "ex-interest" date for an interest
                                        payment, so that as a result a
                                        scheduled Interest Payment Date will
                                        not occur, the Issuer shall cause the
                                        Calculation Agent to give notice to the
                                        Trustee and to the Depositary, in each
                                        case in the manner and at the time
                                        described in the second and third
                                        paragraphs under "Morgan Stanley Call
                                        Right" below, that no Interest Payment
                                        Date will occur after such Morgan
                                        Stanley Notice Date.

                                        shall, in the absence of manifest
                                        error, be conclusive for all purposes

Antidilution Adjustments..............  The Exchange Ratio shall be adjusted as
                                        follows:

                                           1. If NVIDIA Stock is subject to a
                                        stock split or reverse stock split,
                                        then once such split has become
                                        effective, the Exchange Ratio shall be
                                        adjusted to equal the product of the
                                        prior Exchange Ratio and the number

                                      A-10

                                        of shares issued in such stock split or
                                        reverse stock split with respect to one
                                        share of NVIDIA Stock.

                                           2. If NVIDIA Stock is subject (i) to
                                        a stock dividend (issuance of
                                        additional shares of NVIDIA Stock) that
                                        is given ratably to all holders of
                                        shares of NVIDIA Stock or (ii) to a
                                        distribution of NVIDIA Stock as a
                                        result of the triggering of any
                                        provision of the corporate charter of
                                        NVIDIA, then once the dividend has
                                        become effective and NVIDIA Stock is
                                        trading ex-dividend, the Exchange Ratio
                                        shall be adjusted so that the new
                                        Exchange Ratio shall equal the prior
                                        Exchange Ratio plus the product of (i)
                                        the number of shares issued with
                                        respect to one share of NVIDIA Stock
                                        and (ii) the prior Exchange Ratio.

                                           3. If NVIDIA issues rights or
                                        warrants to all holders of NVIDIA Stock
                                        to subscribe for or purchase NVIDIA
                                        Stock at an exercise price per share
                                        less than the Market Price of NVIDIA
                                        Stock on both (i) the date the exercise
                                        price of such rights or warrants is
                                        determined and (ii) the expiration date
                                        of such rights or warrants, and if the
                                        expiration date of such rights or
                                        warrants precedes the maturity of this
                                        SPARQS, then the Exchange Ratio shall
                                        be adjusted to equal the product of the
                                        prior Exchange Ratio and a fraction,
                                        the numerator of which shall be the
                                        number of shares of NVIDIA Stock
                                        outstanding immediately prior to the
                                        issuance of such rights or warrants
                                        plus the number of additional shares of
                                        NVIDIA Stock offered for subscription
                                        or purchase pursuant to such rights or
                                        warrants and the denominator of which
                                        shall be the number of shares of NVIDIA
                                        Stock outstanding immediately prior to
                                        the issuance of such rights or warrants
                                        plus the number of additional shares of
                                        NVIDIA Stock which the aggregate
                                        offering price of the total number of
                                        shares of NVIDIA Stock so offered for
                                        subscription or purchase pursuant to
                                        such rights or warrants would purchase
                                        at the Market Price on the expiration
                                        date of such rights or warrants, which
                                        shall be determined by multiplying such
                                        total number of shares offered by the
                                        exercise price of such rights or
                                        warrants and dividing the product so
                                        obtained by such Market Price.

                                           4. There shall be no adjustments to
                                        the Exchange Ratio to reflect cash
                                        dividends or other distributions paid
                                        with respect to NVIDIA Stock other than

                                        an Extraordinary Dividend, the Exchange
                                        Ratio with respect to NVIDIA Stock
                                        shall be adjusted on the ex-dividend
                                        date so that the new Exchange Ratio
                                        shall equal the product of (i) the
                                        prior Exchange Ratio and (ii) a

                                        of the Base Market Price, then, instead
                                        of adjusting the Exchange Ratio, the

transfer instructions have been received by the Paying Agent in writing, with
respect to payments of interest, on or prior to the fifth Business Day after
the applicable Record Date and, with respect to payments of principal or any
premium, at least ten Business Days prior to the Maturity Date or any
redemption or repayment date, as the case may be; provided that, if payment of
interest, principal or any premium with regard to this Note is payable in euro,
the account must be a euro account in a country for which the euro is the
lawful currency, provided, further, that if such wire transfer instructions are
not received, such payments will be made by check payable in such Specified
Currency mailed to the address of the person entitled thereto as such address
shall appear in the Note register; and provided, further, that payment of the
principal of this Note, any premium and the interest due at maturity (or on any
redemption or repayment date) will be made upon surrender of this Note at the
office or agency referred to in the preceding paragraph.

     If so indicated on the face hereof, the holder of this Note, if
denominated in a Specified Currency other than U.S. dollars, may elect to
receive all or a portion of payments on this Note in U.S. dollars by
transmitting a written request to the Paying Agent, on or prior to the fifth
Business Day after such Record Date or at least ten Business Days prior to the
Maturity Date or any redemption or repayment date, as the case may be. Such
election shall remain in effect unless such request is revoked by written
notice to the Paying Agent as to all or a portion of payments on this Note at
least five Business Days prior to such Record Date, for payments of interest,
or at least ten days prior to the Maturity Date or any redemption or repayment
date, for payments of principal, as the case may be.

     If the holder elects to receive all or a portion of payments of principal
of and any premium and interest on this Note, if denominated in a Specified
Currency other than U.S. dollars, in U.S. dollars, the Exchange Rate Agent (as
defined on the reverse hereof) will convert such payments into U.S. dollars. In
the event of such an election, payment in respect of this Note will be based
upon the exchange rate as determined by the Exchange Rate Agent based on the
highest bid quotation in The City of New York received by such Exchange Rate
Agent at approximately 11:00 a.m., New York City time, on the second Business
Day preceding the applicable payment date from three recognized foreign
exchange dealers (one of which may be the Exchange Rate Agent unless such
Exchange Rate Agent is an affiliate of the Issuer) for the purchase by the
quoting dealer of U.S. dollars for the Specified Currency for settlement on
such payment date in the amount of the Specified Currency payable in the
absence of such an election to such holder and at which the applicable dealer
commits to execute a contract. If such bid quotations are not available, such
payment will be made in the Specified Currency. All currency exchange costs
will be borne by the holder of this Note by deductions from such payments.

                              REVERSE OF SECURITY

     This Note is one of a duly authorized issue of Senior Global Medium-Term
Notes, Series C, having maturities more than nine months from the date of issue
(the "Notes") of the Issuer. The Notes are issuable under an Amended and
Restated Senior Indenture, dated as of May 1, 1999, between the Issuer and
JPMorgan Chase Bank (formerly known as The Chase Manhattan Bank), as Trustee
(the "Trustee," which term includes any successor trustee under the Senior
Indenture) (as may be amended or supplemented from time to time, the "Senior
Indenture"), to which Senior Indenture and all indentures supplemental thereto
reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities of the Issuer, the Trustee and holders of the
Notes and the terms upon which the Notes are, and are to be, authenticated and
delivered. The Issuer has appointed JPMorgan Chase Bank at its corporate trust
office in The City of New York as the paying agent (the "Paying Agent," which
term includes any additional or successor Paying Agent appointed by the Issuer)
with respect to the Notes. The terms of individual Notes may vary with respect
to interest rates, interest rate formulas, issue dates, maturity dates, or
otherwise, all as provided in the Senior Indenture. To the extent not
inconsistent herewith, the terms of the Senior Indenture are hereby
incorporated by reference herein.

     Unless otherwise indicated on the face hereof, this Note will not be
subject to any sinking fund and, unless otherwise provided on the face hereof
in accordance with the provisions of the following two paragraphs, will not be
redeemable or subject to repayment at the option of the holder prior to
maturity.

     If so indicated on the face hereof, this Note may be redeemed in whole or
in part at the option of the Issuer on or after the Initial Redemption Date
specified on the face hereof on the terms set forth on the face hereof,
together with interest accrued and unpaid hereon to the date of redemption. If
this Note is subject to "Annual Redemption Percentage Reduction," the Initial
Redemption Percentage indicated on the face hereof will be reduced on each
anniversary of the Initial Redemption Date by the Annual Redemption Percentage
Reduction specified on the face hereof until the redemption price of this Note
is 100% of the principal amount hereof, together with interest accrued and
unpaid hereon to the date of redemption. Notice of redemption shall be mailed
to the registered holders of the Notes designated for redemption at their
addresses as the same shall appear on the Note register not less than 30 nor
more than 60 calendar days prior to the date fixed for redemption or within the
Redemption Notice Period specified on the face hereof, subject to all the
conditions and provisions of the Senior Indenture. In the event of redemption
of this Note in part only, a new Note or Notes for the amount of the unredeemed
portion hereof shall be issued in the name of the holder hereof upon the
cancellation hereof.

     If so indicated on the face of this Note, this Note will be subject to
repayment at the option of the holder on the Optional Repayment Date or Dates
specified on the face hereof on the terms set forth herein. On any Optional
Repayment Date, this Note will be repayable in whole or in part in increments
of $1,000 or, if this Note is denominated in a Specified Currency other than
U.S. dollars, in increments of 1,000 units of such Specified Currency (provided
that any remaining principal amount hereof shall not be less than the minimum
authorized denomination hereof) at the option of the holder hereof at a price
equal to 100% of the principal amount to be repaid, together with interest
accrued and unpaid hereon to the date of repayment. For this Note to be repaid
at the option of the holder hereof, the Paying Agent must receive at its
corporate trust office in the Borough of

                                      A-25
<PAGE>

Manhattan, The City of New York, at least 15 but not more than 30 calendar days
prior to the date of repayment, (i) this Note with the form entitled "Option to
Elect Repayment" below duly completed or (ii) a telegram, telex, facsimile
transmission or a letter from a member of a national securities exchange or the
National Association of Securities Dealers, Inc. or a commercial bank or a
trust company in the United States setting forth the name of the holder of this
Note, the principal amount hereof, the certificate number of this Note or a
description of this Note's tenor and terms, the principal amount hereof to be
repaid, a statement that the option to elect repayment is being exercised
thereby and a guarantee that this Note, together with the form entitled "Option
to Elect Repayment" duly completed, will be received by the Paying Agent not
later than the fifth Business Day after the date of such telegram, telex,
facsimile transmission or letter; provided, that such telegram, telex,
facsimile transmission or letter shall only be effective if this Note and form
duly completed are received by the Paying Agent by such fifth Business Day.
Exercise of such repayment option by the holder hereof shall be irrevocable. In
the event of repayment of this Note in part only, a new Note or Notes for the
amount of the unpaid portion hereof shall be issued in the name of the holder
hereof upon the cancellation hereof.

     Interest payments on this Note will include interest accrued to but
excluding the Interest Payment Dates or the Maturity Date (or any earlier
redemption or repayment date), as the case may be. Unless otherwise provided on
the face hereof, interest payments for this Note will be computed and paid on
the basis of a 360-day year of twelve 30-day months.

     In the case where the Interest Payment Date or the Maturity Date (or any
redemption or repayment date) does not fall on a Business Day, payment of
interest, premium, if any, or principal otherwise payable on such date need not
be made on such date, but may be made on the next succeeding Business Day with
the same force and effect as if made on the Interest Payment Date or on the
Maturity Date (or any redemption or repayment date), and no interest on such
payment shall accrue for the period from and after the Interest Payment Date or
the Maturity Date (or any redemption or repayment date) to such next succeeding
Business Day.

     This Note and all the obligations of the Issuer hereunder are direct,
unsecured obligations of the Issuer and rank without preference or priority
among themselves and pari passu with all other existing and future unsecured
and unsubordinated indebtedness of the Issuer, subject to certain statutory
exceptions in the event of liquidation upon insolvency.

     This Note, and any Note or Notes issued upon transfer or exchange hereof,
is issuable only in fully registered form, without coupons, and, if denominated
in U.S. dollars, unless otherwise stated above, is issuable only in
denominations of U.S. $1,000 and any integral multiple of U.S. $1,000 in excess
thereof. If this Note is denominated in a Specified Currency other than U.S.
dollars, then, unless a higher minimum denomination is required by applicable
law, it is issuable only in denominations of the equivalent of U.S. $1,000
(rounded to an integral multiple of 1,000 units of such Specified Currency), or
any amount in excess thereof which is an integral multiple of 1,000 units of
such Specified Currency, as determined by reference to the noon dollar buying
rate in The City of New York for cable transfers of such Specified Currency
published by the Federal Reserve Bank of New York (the "Market Exchange Rate")
on the Business Day immediately preceding the date of issuance.

     The Trustee has been appointed registrar for the Notes, and the Trustee
will maintain at its office in The City of New York a register for the
registration and transfer of Notes. This Note may be transferred at the
aforesaid office of the Trustee by surrendering this Note for cancellation,
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and duly executed by the registered holder hereof in person or by the
holder's attorney duly authorized in writing, and thereupon the Trustee shall
issue in the name of the transferee or transferees, in exchange herefor, a new
Note or Notes having identical terms and provisions and having a like aggregate
principal amount in authorized denominations, subject to the terms and
conditions set forth herein; provided, however, that the Trustee will not be
required (i) to register the transfer of or exchange any Note that has been
called for redemption in whole or in part, except the unredeemed portion of
Notes being redeemed in part, (ii) to register the transfer of or exchange any
Note if the holder thereof has exercised his right, if any, to require the
Issuer to repurchase such Note in whole or in part, except the portion of such
Note not required to be repurchased, or (iii) to register the transfer of or
exchange Notes to the extent and during the period so provided in the Senior
Indenture with respect to the redemption of Notes. Notes are exchangeable at
said office for other Notes of other authorized denominations of equal
aggregate principal amount having identical terms and provisions. All such
exchanges and transfers of Notes will be free of charge, but the Issuer may
require payment of a sum sufficient to cover any tax or other governmental
charge in connection therewith. All Notes surrendered for exchange shall be
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and executed by the registered holder in person or by the holder's
attorney duly authorized in writing. The date of registration of any Note
delivered upon any exchange or transfer of Notes shall be such that no gain or
loss of interest results from such exchange or transfer.

     In case this Note shall at any time become mutilated, defaced or be
destroyed, lost or stolen and this Note or evidence of the loss, theft or
destruction thereof (together with the indemnity hereinafter referred to and
such other documents or proof as may be required in the premises) shall be
delivered to the Trustee, the Issuer in its discretion may execute a new Note
of like tenor in exchange for this Note, but, if this Note is destroyed, lost
or stolen, only upon receipt of evidence satisfactory to the Trustee and the
Issuer that this Note was destroyed or lost or stolen and, if required, upon
receipt also of indemnity satisfactory to each of them. All expenses and
reasonable charges associated with procuring such indemnity and with the
preparation, authentication and delivery of a new Note shall be borne by the
owner of the Note mutilated, defaced, destroyed, lost or stolen.

     The Senior Indenture provides that (a) if an Event of Default (as defined
in the Senior Indenture) due to the default in payment of principal of,
premium, if any, or interest on, any series of debt securities issued under the
Senior Indenture, including the series of Senior Medium-Term Notes of which
this Note forms a part, or due to the default in the performance or breach of
any other covenant or warranty of the Issuer applicable to the debt securities
of such series but not applicable to all outstanding debt securities issued
under the Senior Indenture shall have occurred and be continuing, either the
Trustee or the holders of not less than 25% in principal amount of the debt
securities of each affected series (voting as a single class) may then declare
the principal of all debt securities of all such series and interest accrued
thereon to be due and payable immediately and (b) if an Event of Default due to
a default in the performance of any other of the covenants or agreements in the
Senior Indenture applicable to all outstanding debt securities issued
thereunder, including this Note, or due to certain events of bankruptcy or
insolvency of the Issuer, shall have

                                      A-27
<PAGE>

occurred and be continuing, either the Trustee or the holders of not less than
25% in principal amount of all debt securities issued under the Senior
Indenture then outstanding (treated as one class) may declare the principal of
all such debt securities and interest accrued thereon to be due and payable
immediately, but upon certain conditions such declarations may be annulled and
past defaults may be waived (except a continuing default in payment of
principal (or premium, if any) or interest on such debt securities) by the
holders of a majority in principal amount of the debt securities of all
affected series then outstanding.

     If the face hereof indicates that this Note is subject to "Modified
Payment upon Acceleration," then (i) if the principal hereof is declared to be
due and payable as described in the preceding paragraph, the amount of
principal due and payable with respect to this Note shall be limited to the
aggregate principal amount hereof multiplied by the sum of the Issue Price
specified on the face hereof (expressed as a percentage of the aggregate
principal amount) plus the original issue discount amortized from the Interest
Accrual Date to the date of declaration, which amortization shall be calculated
using the "interest method" (computed in accordance with generally accepted
accounting principles in effect on the date of declaration), (ii) for the
purpose of any vote of securityholders taken pursuant to the Senior Indenture
prior to the acceleration of payment of this Note, the principal amount hereof
shall equal the amount that would be due and payable hereon, calculated as set
forth in clause (i) above, if this Note were declared to be due and payable on
the date of any such vote and (iii) for the purpose of any vote of
securityholders taken pursuant to the Senior Indenture following the
acceleration of payment of this Note, the principal amount hereof shall equal
the amount of principal due and payable with respect to this Note, calculated
as set forth in clause (i) above.

     If the face hereof indicates that this Note is subject to "Tax Redemption
and Payment of Additional Amounts," this Note may be redeemed, as a whole, at
the option of the Issuer at any time prior to maturity, upon the giving of a
notice of redemption as described below, at a redemption price equal to 100% of
the principal amount hereof, together with accrued interest to the date fixed
for redemption (except that if this Note is subject to "Modified Payment upon
Acceleration or Redemption," such redemption price would be limited to the
aggregate principal amount hereof multiplied by the sum of the Issue Price
specified on the face hereof (expressed as a percentage of the aggregate
principal amount) plus the original issue discount amortized from the Interest
Accrual Date to the date of redemption, which amortization shall be calculated
using the "interest method" (computed in accordance with generally accepted
accounting principles in effect on the date of redemption) (the "Amortized
Amount")), if the Issuer determines that, as a result of any change in or
amendment to the laws (or any regulations or rulings promulgated thereunder) of
the United States or of any political subdivision or taxing authority thereof
or therein affecting taxation, or any change in official position regarding the
application or interpretation of such laws, regulations or rulings, which
change or amendment becomes effective on or after the Initial Offering Date
hereof, the Issuer has or will become obligated to pay Additional Amounts (as
defined below) with respect to this Note as described below. Prior to the
giving of any notice of redemption pursuant to this paragraph, the Issuer shall
deliver to the Trustee (i) a certificate stating that the Issuer is entitled to
effect such redemption and setting forth a statement of facts showing that the
conditions precedent to the right of the Issuer to so redeem have occurred, and
(ii) an opinion of independent counsel satisfactory to the Trustee to such
effect based on such statement of facts; provided that no such notice of
redemption shall be given earlier than 60 calendar days prior to the earliest
date on which

                                      A-28
<PAGE>

the Issuer would be obligated to pay such Additional Amounts if a payment in
respect of this Note were then due.

     Notice of redemption will be given not less than 30 nor more than 60
calendar days prior to the date fixed for redemption or within the Redemption
Notice Period specified on face hereof, which date and the applicable
redemption price will be specified in the notice.

     If the face hereof indicates that this Note is subject to "Tax Redemption
and Payment of Additional Amounts," the Issuer will, subject to certain
exceptions and limitations set forth below, pay such additional amounts (the
"Additional Amounts") to the holder of this Note who is a United States Alien
as may be necessary in order that every net payment of the principal of and
interest on this Note and any other amounts payable on this Note, after
withholding for or on account of any present or future tax, assessment or
governmental charge imposed upon or as a result of such payment by the United
States (or any political subdivision or taxing authority thereof or therein),
will not be less than the amount provided for in this Note to be then due and
payable. The Issuer will not, however, be required to make any payment of
Additional Amounts to any such holder for or on account of:

          (a) any such tax, assessment or other governmental charge that would
     not have been so imposed but for (i) the existence of any present or
     former connection between such holder (or between a fiduciary, settlor,
     beneficiary, member or shareholder of such holder, if such holder is an
     estate, a trust, a partnership or a corporation) and the United States and
     its possessions, including, without limitation, such holder (or such
     fiduciary, settlor, beneficiary, member or shareholder) being or having
     been a citizen or resident thereof or being or having been engaged in a
     trade or business or present therein or having, or having had, a permanent
     establishment therein or (ii) the presentation by the holder of this Note
     for payment on a date more than 15 calendar days after the date on which
     such payment became due and payable or the date on which payment thereof
     is duly provided for, whichever occurs later;

          (b) any estate, inheritance, gift, sales, transfer or personal
     property tax or any similar tax, assessment or governmental charge;

          (c) any tax, assessment or other governmental charge imposed by
     reason of such holder's past or present status as a personal holding
     company or foreign personal holding company or controlled foreign
     corporation or passive foreign investment company with respect to the
     United States or as a corporation which accumulates earnings to avoid
     United States federal income tax or as a private foundation or other
     tax-exempt organization or a bank receiving interest under Section
     881(c)(3)(A) of the Internal Revenue Code of 1986, as amended;

          (d) any tax, assessment or other governmental charge that is payable
     otherwise than by withholding from payments on or in respect of this Note;

          (e) any tax, assessment or other governmental charge required to be
     withheld by any Paying Agent from any payment of principal of, or interest
     on, this Note, if such payment can be made without such withholding by any
     other Paying Agent in a city in Western Europe;

                                      A-29
<PAGE>

          (f) any tax, assessment or other governmental charge that would not
     have been imposed but for the failure to comply with certification,
     information or other reporting requirements concerning the nationality,
     residence or identity of the holder or beneficial owner of this Note, if
     such compliance is required by statute or by regulation of the United
     States or of any political subdivision or taxing authority thereof or
     therein as a precondition to relief or exemption from such tax, assessment
     or other governmental charge;

          (g) any tax, assessment or other governmental charge imposed by
     reason of such holder's past or present status as the actual or
     constructive owner of 10% or more of the total combined voting power of
     all classes of stock entitled to vote of the Issuer or as a direct or
     indirect subsidiary of the Issuer; or

          (h) any combination of items (a), (b), (c), (d), (e), (f) or (g).

In addition, the Issuer shall not be required to make any payment of Additional
Amounts (i) to any such holder where such withholding or deduction is imposed
on a payment to an individual and is required to be made pursuant to any
European Union Directive on the taxation of savings implementing the agreement
reached in the ECOFIN Council meeting of 13 December 2001 or any law
implementing or complying with, or introduced in order to conform to, such
Directive; or (ii) by or on behalf of a holder who would have been able to
avoid such withholding or deduction by presenting this Note or the relevant
coupon to another Paying Agent in a member state of the European Union. Nor
shall Additional Amounts be paid with respect to any payment on this Note to a
United States Alien who is a fiduciary or partnership or other than the sole
beneficial owner of such payment to the extent such payment would be required
by the laws of the United States (or any political subdivision thereof) to be
included in the income, for tax purposes, of a beneficiary or settlor with
respect to such fiduciary or a member of such partnership or a beneficial owner
who would not have been entitled to the Additional Amounts had such
beneficiary, settlor, member or beneficial owner been the holder of this Note.

     The Senior Indenture permits the Issuer and the Trustee, with the consent
of the holders of not less than a majority in aggregate principal amount of the
debt securities of all series issued under the Senior Indenture then
outstanding and affected (voting as one class), to execute supplemental
indentures adding any provisions to or changing in any manner the rights of the
holders of each series so affected; provided that the Issuer and the Trustee
may not, without the consent of the holder of each outstanding debt security
affected thereby, (a) extend the final maturity of any such debt security, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any amount payable on redemption or
repayment thereof, or change the currency of payment thereof, or modify or
amend the provisions for conversion of any currency into any other currency, or
modify or amend the provisions for conversion or exchange of the debt security
for securities of the Issuer or other entities (other than as provided in the
antidilution provisions or other similar adjustment provisions of the debt
securities or otherwise in accordance with the terms thereof), or impair or
affect the rights of any holder to institute suit for the payment thereof
without the consent of the holder of each debt security so affected or (b)
reduce the aforesaid percentage in principal amount of debt securities the
consent of the holders of which is required for any such supplemental
indenture.

     Except as set forth below, if the principal of, premium, if any, or
interest on, this Note is payable in a Specified Currency other than U.S.
dollars and such Specified Currency is not available to the Issuer for making
payments hereon due to the imposition of exchange controls or other
circumstances beyond the control of the Issuer or is no longer used by the
government of the country issuing such currency or for the settlement of
transactions by public institutions within the international banking community,
then the Issuer will be entitled to satisfy its obligations to the holder of
this Note by making such payments in U.S. dollars on the basis of the Market
Exchange Rate on the date of such payment or, if the Market Exchange Rate is
not available on such date, as of the most recent practicable date; provided,
however, that if the euro has been substituted for such Specified Currency, the
Issuer may at its option (or shall, if so required by applicable law) without
the consent of the holder of this Note effect the payment of principal of,
premium, if any, or interest on, any Note denominated in such Specified
Currency in euro in lieu of such Specified Currency in conformity with legally
applicable measures taken pursuant to, or by virtue of, the treaty establishing
the European Community, as amended. Any payment made under such circumstances
in U.S. dollars or euro where the required payment is in an unavailable
Specified Currency will not constitute an Event of Default. If such Market
Exchange Rate is not then available to the Issuer or is not published for a
particular Specified Currency, the Market Exchange Rate will be based on the
highest bid quotation in The City of New York received by the Exchange Rate
Agent at approximately 11:00 a.m., New York City time, on the second Business
Day preceding the date of such payment from three recognized foreign exchange
dealers (the "Exchange Dealers") for the purchase by the quoting Exchange
Dealer of the Specified Currency for U.S. dollars for settlement on the payment
date, in the aggregate amount of the Specified Currency payable to those
holders or beneficial owners of Notes and at which the applicable Exchange
Dealer commits to execute a contract. One of the Exchange Dealers providing
quotations may be the Exchange Rate Agent unless the Exchange Rate Agent is an
affiliate of the Issuer. If those bid quotations are not available, the
Exchange Rate Agent shall determine the market exchange rate at its sole
discretion.

     The "Exchange Rate Agent" shall be Morgan Stanley & Co. Incorporated,
unless otherwise indicated on the face hereof.

     All determinations referred to above made by, or on behalf of, the Issuer
or by, or on behalf of, the Exchange Rate Agent shall be at such entity's sole
discretion and shall, in the absence of manifest error, be conclusive for all
purposes and binding on holders of Notes and coupons.

     So long as this Note shall be outstanding, the Issuer will cause to be
maintained an office or agency for the payment of the principal of and premium,
if any, and interest on this Note as herein provided in the Borough of
Manhattan, The City of New York, and an office or agency in said Borough of
Manhattan for the registration, transfer and exchange as aforesaid of the
Notes. The Issuer may designate other agencies for the payment of said
principal, premium and interest at such place or places (subject to applicable
laws and regulations) as the Issuer may decide. So long as there shall be such
an agency, the Issuer shall keep the Trustee advised of the names and locations
of such agencies, if any are so designated. If any European Union Directive on
the taxation of savings implementing the agreement reached in the ECOFIN
Council meeting of 13 December 2001 or any law implementing or complying with,
or introduced in order to conform to, such Directive is introduced and a Paying
Agent has been designated within the European Union, the Issuer will maintain a
Paying Agent in a member state of the European Union that will not be obligated
to withhold or deduct tax pursuant to any such Directive or law.

     With respect to moneys paid by the Issuer and held by the Trustee or any
