<PAGE>

            Section 3. The following definition shall be added to Section 1.01
of the Original Indenture:

            "Carnival plc" means Carnival plc, a public limited company existing
under the laws of England and Wales, and any successor thereto.

            Section 4. The Original Indenture is hereby amended by adding a new
Section 2.19 to read in its entirety as follows:

            "Section 2.19. Carnival plc Guarantee.

            (a) Carnival plc, for value received, hereby unconditionally
      guarantees (the "Carnival plc Guarantee") to the Holders of the Securities
      and to the Trustee on behalf of each such Holder the due and punctual
      payment of the principal of, premium, if any, and interest on such
      Securities, when and as the same shall become due and payable (subject to
      any period of grace provided with respect thereto), whether at the Stated
      Maturity, by declaration of acceleration, call for redemption or
      otherwise, according to the terms thereof and of the Indenture referred to
      therein. In the case of the failure of the Company punctually to make any
      such payment of principal, premium, if any, or interest, Carnival plc
      hereby agrees to cause any such payment to be made punctually when and as
      the same shall become due and payable, whether at the Stated Maturity or
      by declaration of acceleration, call for redemption or otherwise, and as
      if such payment were made by the Company.

            (b) All payments by Carnival plc in respect of the Carnival plc
      Guarantee and the Securities shall be made free and clear of and without
      withholding or deduction for or on account of any present or future taxes,
      duties, assessments or governmental charges of whatever nature imposed or
      levied by or on behalf of the United Kingdom or any political subdivision
      or authority thereof or therein having power to tax ("UK Taxes"), unless
      the withholding or deduction is then required by law. If any deduction or
      withholding for any present or future taxes, duties, assessments or other
      governmental charges of the United Kingdom (or any political subdivision
      or taxing authority within the United Kingdom) will at any time be
      required by the United Kingdom (or any political subdivision or taxing
      authority within the United Kingdom) in respect of the payment of any
      amounts by Carnival plc on the Securities, Carnival plc will pay to a
      Holder of a Security who is not a resident in the United Kingdom for U.K.
      tax purposes such additional amounts ("Carnival plc Additional Amounts")
      as may be necessary in order that the net amounts paid to such Holder,
      after such deduction or withholding, will be not less than the amounts
      specified in new security affected to which its holder is entitled;
      provided that the foregoing obligation to pay Carnival plc Additional
      Amounts does not apply to (i) any tax, duty, assessment or other
      governmental charge which would not have been imposed, withheld or
      deducted but for (1) the existence of any present or former connection
      between the Holder or beneficial owner of a Security (or between a
      fiduciary, settler, beneficiary, member or shareholder or possessor of a
      power over, such holder or

<PAGE>

      beneficial owner, if such Holder or beneficial owner is an estate, trust,
      partnership or corporation) and the United Kingdom (or any political
      subdivision or territory or possession within the United Kingdom or area
      subject to its jurisdiction), including, without limitation, the holder or
      beneficial owner (or the fiduciary, settler, beneficiary, member,
      shareholder or possessor) being or having been domiciliary, national or
      resident thereof or being or having been present or engaged in trade or
      business therein or having or having had a permanent establishment,
      office, branch or fixed base therein or otherwise having or having had
      some connection with the United Kingdom (or such political subdivision,
      territory or possession of the United Kingdom or area subject to its
      jurisdiction) other than the holding or ownership of a Security or the
      collection of principal of and interest, if any, on, or the enforcement
      of, a Security or (2) the presentation of a Security (where presentation
      is required) for payment (x) in the United Kingdom or (y) on a date more
      than 30 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, except to the extent that the Holder would have been
      entitled to the Additional Amounts if it had presented its Security for
      payment on any day within the 30 day period; (ii) any estate, inheritance,
      gift, sale, transfer, personal property or similar tax, assessment or
      other governmental charge; (iii) any tax, duty, assessment or other
      governmental charge which is payable otherwise than by withholding or
      deduction from payment of (or in respect of) principal of, or any interest
      on, the Securities; (iv) any tax, duty, assessment or other governmental
      charge that is imposed, deducted or withheld by reason of the failure to
      comply by the Holder or the beneficial owner of a Security or the
      beneficial owner of any payment on the Security with a request of Carnival
      plc addressed to the Holder to provide information concerning the
      nationality, residence, identity or connection with the United Kingdom or
      any political subdivision or taxing authority thereof of the Holder or
      such beneficial owner or to make any declaration or other similar claim to
      satisfy any information or reporting requirement, which in either case, is
      required or imposed by a statute, treaty, regulation, ruling or
      administrative practice of the taxing jurisdiction as a precondition to
      exemption from withholding or deduction of all or part of such tax, duty,
      assessment or other governmental charge; (v) any tax, duty, assessment or
      other governmental charge which is payable in respect of any payments on a
      certificated Security issued at the request of the Holder on or after the
      occurrence of an Event of Default; or (vi) any combination of the above
      items; nor will Carnival plc Additional Amounts be paid with respect to
      any payment of the principal of, or any interest on, any Security to any
      Holder who is a fiduciary or partnership or other than the sole beneficial
      owner of such payment to the extent the payment would be required by the
      laws of the United Kingdom (or any political subdivision or taxing
      authority within the United Kingdom) to be included in the income for tax
      purposes of a beneficiary or settler with respect to such fiduciary or a
      member of such partnership or to a beneficial owner who would not have
      been entitled to such Carnival plc Additional Amounts had it been the
      Holder of the Security.

<PAGE>

                  Carnival plc shall use commercially reasonable efforts to
      facilitate administrative actions necessary to assist Holders to obtain
      any refund of or credit against UK Taxes for which Carnival plc Additional
      Amounts are not paid as a result of the conditions in the second preceding
      sentence.

            (c) Carnival plc agrees that its obligations under the Carnival plc
      Guarantee shall be absolute and unconditional, irrespective of, and shall
      be unaffected by, any invalidity, irregularity or unenforceability of any
      Security or this Indenture, any failure to enforce the provisions of any
      Security or this Indenture, or any waiver, modification or indulgence
      granted to the Company with respect thereto, by the Holder of any Security
      or the Trustee or any other circumstance which may otherwise constitute a
      legal or equitable discharge of a surety or guarantor; provided, however,
      that, notwithstanding the foregoing, no such waiver, modification or
      indulgence shall, without the consent of Carnival plc, increase the
      principal amount of any Security, or increase the interest rate thereon,
      or increase any premium payable upon redemption thereof, or alter the
      Stated Maturity thereof. Carnival plc hereby waives diligence,
      presentment, demand of payment, filing of claims with a court in the event
      of a merger or bankruptcy of the Company, any right to require a
      proceeding first against the Company, protect or notice with respect to
      any Security or the indebtedness evidenced thereby and all demands
      whatsoever, and covenants that the Carnival plc Guarantee will not be
      discharged except by payment in full of the principal of, premium, if any,
      and interest on such Security.

            (d) The Carnival plc Guarantee is limited to the maximum amount that
      will result in the obligations of Carnival plc not constituting a
      fraudulent conveyance or fraudulent transfer under applicable law.

            (e) Carnival plc shall not consolidate or merge with or into
      (whether or not the Carnival plc is the surviving corporation), or sell,
      convey or transfer or otherwise dispose of all or substantially all of its
      assets in one or more related transactions to another Person, and shall
      not permit any of its Restricted Subsidiaries to enter into any such
      transaction or transactions if such transaction or transactions, in the
      aggregate, would result in a sale, assignment, transfer, lease or disposal
      of all or substantially all of the assets of Carnival plc, as the case may
      be, and its respective Subsidiaries to another Person, unless the
      purchasing or transferee corporation or the successor, continuing or
      resulting corporation in the case of a merger or consolidation (if the
      Carnival plc is not the surviving corporation), as the case may be: (i) is
      an entity in an EU member state, an Organization for Economic Co-operation
      and Development member nation, or a European Free Trade Association member
      nation, in each case other than Greece, Liechtenstein, Mexico or Turkey;
      and (ii) expressly assumes, by an amendment to this Indenture and the
      Securities, pursuant to this Indenture, the obligations of Carnival plc
      under the Carnival plc Guarantee It will be a condition to any
      consolidation, merger, sale of assets or assumption under this section
      that immediately after giving effect to such consolidation, merger, sale
      of assets or assumption no Event of Default (and no event which, after
      notice or lapse of time

<PAGE>

      or both, would become an Event of Default) will have occurred and be
      continuing. Notwithstanding the foregoing, in the case of (1) any merger
      or consolidation by (x) Carnival plc or any of its Restricted Subsidiaries
      with (y) Carnival Corporation or any of its Subsidiaries, (2) any sale,
      conveyance, transfer or other disposition of assets by (x) Carnival plc or
      any of its Restricted Subsidiaries to (y) Carnival Corporation or any of
      its Subsidiaries, clause (i) of the first sentence of this Section 2.19(e)
      shall be deemed to have been satisfied.

            (f) Upon any consolidation or merger or any transfer of all or
      substantially all of the assets of Carnival plc in accordance with Section
      2.19(e) hereof, the successor corporation formed by such consolidation or
      into or with which Carnival plc, is merged or to which such transfer is
      made shall succeed to, and be substituted for (so that from and after the
      date of such consolidation merger, or transfer, the provisions of this
      Indenture referring to "Carnival plc" shall refer instead to the successor
      corporation and not to Carnival plc), and may exercise every right and
      power of Carnival plc under this Indenture with the same effect as if such
      successor Person had been named as Carnival plc herein. Notwithstanding
      the foregoing or any provision of Section 2.19(e), upon any consolidation
      or merger or any transfer of all or substantially all of the assets of
      Carnival plc to the primary obligor under this Indenture or the
      Securities, the Carnival plc Guarantee shall terminate automatically, and
      this Section 2.19 shall be of no further force or effect.

            (g) Carnival plc shall be subrogated to all rights of the Holder of
      each Security and the Trustee against the Company in respect of any
      amounts paid to such Holder by Carnival plc pursuant to the provisions of
      the Carnival plc Guarantee, provided, however, that Carnival plc shall not
      be entitled to enforce, or to receive any payments arising out of or based
      upon, such right of subrogation until the principal of, premium, if any,
      and interest on all Securities of the same series issued under such
      Indenture shall have been paid in full."

            Section 5. The Original Indenture is hereby amended by adding a new
Section 4.11 to read in its entirety as follows:

            "Section 4.11 Carnival Corporation & plc Limitation on Liens.

      Corporation is a primary obligor under this Indenture. At any time that
      Carnival Corporation is not a primary obligor under this Indenture, this
      Section 4.11 shall be of no force or effect. All definitions used in this
      Section 4.11 shall be read for purposes of this Section 4.11 as if the
      term, "Carnival plc", were substituted in such definitions for the term,
      "Carnival Corporation".

            (b) The Company shall not, and shall not permit Carnival plc or any
      Subsidiary of which the Company and/or Carnival plc owns, directly or
      indirectly, at least 80% of such Subsidiary's voting shares to, create,

      of any Debt secured thereby; provided that the principal amount of Debt
      secured thereby will not exceed the principal amount of Debt so secured at
      the time of such extension, renewal, or replacement, and that such
      extension, renewal or replacement Mortgage will be limited to all or any
      part of the same property or shares of stock that secured the Mortgage
      extended, renewed or replaced (plus improvements on such property), or
      property received or shares of stock issued in substitution or exchange
      therefor.

            (c) Notwithstanding Clause (b) of this Section 4.11, the Company,
      Carnival plc or any Subsidiary of which the Company and/or Carnival plc
      owns, directly or indirectly, at least 80% of such Subsidiary's voting
      shares may create, incur, guarantee or assume Debt secured by a Mortgage
      or Mortgages which would otherwise be subject to the foregoing
      restrictions in an aggregate amount which, together with all other such
      Debt of Carnival Corporation & plc secured by a Mortgage or Mortgages and
      Carnival Corporation & plc's Attributable Debt in respect of Carnival
      Corporation & plc Sale and Leaseback Transactions (as defined in Section
      4.12) (other than Attributable Debt in respect of Carnival Corporation &
      plc Sale and Leaseback Transactions permitted because the relevant

<PAGE>

      guarantee or assume such Debt secured by a Mortgage on the property to be
      leased without equally and ratably securing the Securities pursuant to the
      preceding paragraph and other than a Carnival Corporation & plc Sale and
      Leaseback Transaction the proceeds of which have been applied within
      twelve months after its consummation to the Net Proceeds to the retirement
      or repayment of Funded Debt (as described in Section 4.12)), does not at
      the time such Debt is incurred exceed 20% of Consolidated Net Tangible
      Assets."

            Section 6. The Original Indenture is hereby amended by adding a new
Section 4.12 to read in its entirety as follows:

            "Section 4.12 Limitation on Sale and Leaseback Transactions for
Carnival Corporation & plc.

            (a) This Section 4.12 shall be effective so long as Carnival
      Corporation is a primary obligor under this Indenture. At any time that
      Carnival Corporation is not a primary obligor under this Indenture, this
      Section 4.12 shall be of no force or effect. All definitions used in this
      Section 4.12 shall be read for purposes of this Section 4.12 as if the
      term, "Carnival plc", were substituted in such definitions for the term,
      "Carnival Corporation".

            (b) The Company shall not, and shall not permit Carnival plc or any
      Subsidiary of which the Company and/or Carnival plc owns, directly or
      indirectly, at least 80% of such Subsidiary's voting shares to, enter into
      any arrangement with a third party (not including any Carnival Corporation
      & plc Company) providing for the leasing by such Carnival Corporation &
      plc Company for a period, including renewals, in excess of three years, of
      any Principal Property which has been owned by such Carnival Corporation &
      plc Company for more than 270 days and which has been or is to be sold or
      transferred by such Carnival Corporation & plc Company to the third party
      (a "Carnival Corporation & plc Sale and Leaseback Transaction") unless,
      after giving effect thereto, the aggregate amount of all Attributable Debt
      with respect to all of these Carnival Corporation & plc Sale and Leaseback
      Transactions plus all the Debt of Carnival Corporation & plc incurred,
      issued, assumed or guaranteed and secured by a Mortgage or Mortgages (with
      the exception of debt secured by a Mortgage or Mortgages on property that
      any Carnival Corporation & plc Company would be entitled to create, incur,
      issue, guarantee or assume without equally and ratably securing the
      Securities pursuant to the provisions of the Securities pursuant to
      Section 4.11) does not exceed 20% of Consolidated Net Tangible Assets.
      This restriction will not apply to any Carnival Corporation & plc Sale and
      Leaseback Transaction if (i) such Carnival Corporation & plc Company would
      be entitled to create, incur, issue, guarantee or assume Debt secured by a
      Mortgage or Mortgages on the Principal Property to be leased without
      equally and ratably securing the Securities pursuant to the provisions of
      the Securities pursuant to Section 4.11, (ii) within a period commencing
      twelve months prior to the consummation of the Carnival Corporation & plc
      Sale and Leaseback Transaction and ending twelve months after the
      consummation of such Carnival Corporation & plc Sale and Leaseback

<PAGE>

      Transaction, such Carnival Corporation & plc Company has expended or will
      expend for any Principal Property (including capital improvements thereon)
      an amount equal to (x) the Net Proceeds or (y) the part of the Net
      Proceeds which such Carnival Corporation & plc Company has elected not to
      apply in the manner described in the following clause (iii); or (iii) such
      Carnival Corporation & plc Company, within twelve months after the
      consummation of any Carnival Corporation & plc Sale and Leaseback
      Transaction, applies an amount equal to the Net Proceeds (less any amount
      expended for Principal Property under the preceding clause (ii)(y)) to the
      retirement or repayment of Funded Debt of a Carnival Corporation & plc
      Company ranking equally in right of payment with the Securities or Funded
      Debt of a Subsidiary of the Company or Carnival plc. No retirement
      referred to in the preceding clause (iii) may be effected by payment at
      maturity or pursuant to any mandatory sinking fund or prepayment provision
      (unless such repayment is required due to the receipt of the Net
      Proceeds)."

            Section 7. Section 6.01 of the Original Indenture is hereby amended
by deleting the "and" after subclause (v) of Clause (e) thereof, adding the word
"and" after the final semicolon in Clause (f) thereof and adding a new Clause
(g) following such Clause (f), but prior to the proviso to such Section 6.01, to
read in its entirety as follows:

            "(g) if Carnival Corporation is a primary obligor under this
Indenture, the occurrence of any of the following events (all defined terms used
in this Clause (g) being read as if the term, "Carnival plc", were substituted
in such definitions for the term, "Carnival Corporation"):

                  (i) default under any bond, debenture, note or other evidence
            of indebtedness for money borrowed by Carnival plc or any Principal
            Subsidiary of it having an aggregate principal amount outstanding of
            the greater of (pound)25,000,000 or 0.5% of Consolidated Net
            Tangible Assets (or their respective equivalents in any other
            currency) or under any mortgage, indenture or instrument under which
            there may be issued or by which there may be secured or evidenced
            any indebtedness for money borrowed by Carnival plc or any Principal
            Subsidiary of it, whether such indebtedness now exists or will
            hereafter be created which default will have resulted in such
            indebtedness of the greater of (pound)25,000,000 or 0.5% (or their
            respective equivalents in any other currency) of Consolidated Net
            Tangible Assets becoming or being declared due and payable prior to
            the date on which it would otherwise have become due and payable,
            without such indebtedness having been discharged, or such
            acceleration having been rescinded or annulled, within a period of
            30 days after written notice is provided to the Company;

                  (ii) Carnival plc or any Principal Subsidiary of it pursuant
            to or within the meaning of Bankruptcy Law: (1) commences a
            voluntary case, (2) consents to the entry of an order for relief
            against it in an involuntary case, (3) consents to the appointment
            of a Custodian of it or for all or substantially all of its
            property, (4) makes a general assignment for the

            as they become due;

                  (iii) a court of competent jurisdiction enters an order or
            decree under any Bankruptcy Law that: (1) is for relief against
            Carnival plc in an involuntary case, (2) appoints a Custodian of
            Carnival plc or any Principal Subsidiary of it or for all or
            substantially all of the property of Carnival plc or any Principal
            Subsidiary of it; or (3) orders the liquidation of Carnival plc or
            any Principal Subsidiary of it; and, in any such case, the order or
            decree remains unstayed and in effect for 90 consecutive days;"

            Section 8. Section 6.01 of the Original Indenture is hereby amended
by adding the following prior to the final period in such Section:

            "; provided, further, that there will not be an Event of Default
under Clause (g)(i) if the bond, debenture, note or other evidence of
indebtedness in question is the subject of non-recourse financing arrangement
under which the lender's right of recourse is limited to a specific asset and
there is no further recourse by the relevant creditor against the general assets
of Carnival plc or any Principal Subsidiary of it; and provided further, that it
will not be an Event of Default under Clause (g)(ii) or (g)(iii) if the event in
question relates solely to property of Carnival plc or a Principal Subsidiary of
it that is the subject of a non-recourse financing arrangement described in the
previous proviso, and if such event does not, directly or indirectly, give
further recourse by the relevant creditor to the general assets (or any other
property) of Carnival plc or a Principal Subsidiary of it."

            Section 9. Section 6.02 of the Original Indenture is hereby amended
by adding the following after the final sentence thereof: "If Carnival
Corporation is a primary obligor under this Indenture and if an Event of Default
specified in subclauses (ii) or (iii) of Clause (g) of Section 6.01 hereof
occurs with respect to Carnival plc, the Securities then outstanding shall ipso
facto become and be immediately due and payable at 100% of the outstanding
principal amount thereof plus premium and accrued and unpaid interest, to the
date of such Event of Default, without any declaration or other act on the part
of the Trustee or any Holder."

            Section 10. Notices to the Company under the Indenture shall be sent
to: Carnival Corporation, 3655 N.W. 87th Avenue, Miami, Florida, 33178,

            Section 11. Carnival Corporation, Carnival plc and POPCIL

            Section 12. Each of Carnival Corporation and Carnival plc (i)
acknowledges that it has, by separate written instrument, designated and
appointed National Registered Agents as its authorized agent upon which process
may be served in any suit or proceeding arising out of or relating to the
Indenture, the Securities or the Carnival plc Guarantee that may be instituted
in any federal or state court in the Borough of Manhattan, The City of New York
or brought under federal or state securities laws or brought by the Trustee in
its capacity as a trustee under the Indenture, and acknowledges that National
Registered Agents has accepted such designation, (ii) submits to the
jurisdiction of any such court in any such suit or proceeding and waives any
objection which it may now or hereafter have to the laying of venue of any such
proceeding or any claim of inconvenient forum, and (iii) agrees that service of
process upon National Registered Agents and written notice of said service to it
(mailed or delivered to its secretary at its registered office at 875 Avenue of
the Americas, Suite 501, New York, New York, 10001 or at any other address
previously furnished in writing to the Trustee) shall be deemed in every respect
effective service of process upon it in any such suit or proceeding. Each of
Carnival Corporation and Carnival plc further agrees to take any and all action,
including the execution and filing of any and all such documents and
instruments, as may be necessary to continue such designation and appointment of
National Registered Agents with respect to it in full force and effect so long
as the Indenture shall be in full force and effect and so long as any of the
Securities shall be outstanding, subject to the appointment of a successor
pursuant to the following sentence. Carnival Corporation or Carnival plc may
appoint a successor to National Registered Agents, provided that such successor
shall be located in the Borough of Manhattan, The City of New York and

action as may be necessary to continue such designation and appointment of such
successor in full force and effect so long as the Indenture is in full force and
effect. To the extent that Carnival Corporation or Carnival plc has or hereafter
may acquire any immunity from jurisdiction of any court or from any legal
process (whether through service of notice, attachment prior to judgment,
attachment in aid of execution or otherwise) with respect to itself or its
property, it hereby irrevocably waives such immunity in respect of its
respective obligations under the Indenture and the Securities to the fullest
extent permitted by law.
