successor corporation to Carnival Corporation) or such political subdivision or
otherwise having or having had some connection with the Republic of Panama (or
the jurisdiction of incorporation of a successor corporation to Carnival
Corporation) or such political subdivision 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, (ii) any present or future Panamanian Taxes
which would not have been so imposed, assessed, levied or collected but for the
fact that, where presentation is required, such Security was presented for
payment on a date more than thirty days after the date such payment became due
and payable or was provided for, whichever is later, except to the extent that
the holder would have been entitled to Carnival Additional Amounts if it had
presented its Security for payment on any day within the 30 day period, (iii)
any present or future Panamanian Taxes which would not have been so imposed,
assessed, levied or collected but for the failure to comply by the holder with a
request of Carnival Corporation addressed to the holder to provide information
concerning the nationality, residence, identity or connection with the Republic
of Panama (or the jurisdiction of incorporation of a successor corporation to
Carnival Corporation) or any political subdivision or taxing authority thereof
of the holder or beneficial owner of such Security or to make any declaration or
other similar claim to satisfy any information or reporting requirement, which
in either case, is required by statute or by rules or regulations of the
Republic of Panama (or the jurisdiction of incorporation of a successor
corporation to Carnival Corporation) or such political subdivision or taxing
authority as a precondition to relief or exemption from withholding or deduction
of any Panamanian Taxes, (iv) any estate, inheritance, gift, sale, transfer,
personal property or similar tax, assessment or other governmental charge; (v)
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; (vi) 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 (vii) any combination of the above items;
nor will Carnival Additional Amounts be paid with respect to any payment of
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 Republic of Panama (or
the jurisdiction of incorporation of a successor corporation to Carnival
Corporation) or any political subdivision or taxing authority thereof or therein
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 Additional Amounts had
it been the Holder of the Security. The provisions described in (i) through
(vii) above are referred to herein as "Excluded Taxes." The Company shall cause
Carnival Corporation to indemnify and hold harmless each holder of a Security
and upon written request reimburse each holder for the amount of (i) any
Panamanian Taxes levied or imposed and paid by such holder of a Security (other
than Excluded Taxes) as a result of payments made with respect to such Security,
(ii) any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto, and (iii) any Panamanian Taxes with respect
to payment of Carnival Additional Amounts or any reimbursement pursuant to this
sentence. The Company shall cause Carnival Corporation to (1) make such
withholding or deduction and (2) remit the full amount deducted or withheld to
the relevant authority in accordance with applicable law.



                                                                              10


                  The Company shall, and shall cause Carnival Corporation to,
use commercially reasonable efforts to facilitate administrative actions
necessary to assist Holders to obtain any refund of or credit against Panamanian
Taxes for which Carnival Additional Amounts are not paid as a result of the
conditions in the preceding paragraph."

                  SECTION 8.        Section 5.01 of the Original Indenture is
hereby amended by adding the following text at the end of the first paragraph
thereof:

                  "Notwithstanding the foregoing, if the Carnival Corporation

conveyance, transfer or other disposition of assets and such transaction is not
prohibited by the DLC Agreements, in the case of (i) any merger or consolidation
by (x) the Company, the Guarantor or any Restricted Subsidiaries with (y)
Carnival Corporation or any of its Subsidiaries, (ii) any sale, conveyance,
transfer or other disposition of assets by (x) the Company, the Guarantor or any
Restricted Subsidiaries to (y) Carnival Corporation or any of its Subsidiaries,

indenture or instrument under which there may be issued or by which there may be
secured or evidenced any indebtedness for money borrowed by the Company,
Carnival Corporation or any Principal Subsidiary, 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;"

                  SECTION 10.       Section 6.01(e) of the Original Indenture is

                                    property,

                           (iv)     makes a general assignment for the benefit
                                    of its creditors, or

hereby amended and restated in its entirety to read as follows:

                  "(f) a court of competent jurisdiction enters an order or
decree under any Bankruptcy Law that:

                           (i)      is for relief against the Company, Carnival

                  and the order or decree remains unstayed and in effect for 90
consecutive days;

                  PROVIDED, HOWEVER, that there will not be an Event of Default
under Section 6.01(d) 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 the Company, Carnival Corporation, the Guarantor or any Principal Subsidiary;
and PROVIDED FURTHER, that it will not be an Event of Default under Clause (e)
and (f) if the event in question relates solely to property of the Company,
Carnival Corporation, the Guarantor or a Principal Subsidiary 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 the Company, Carnival Corporation, the Guarantor or a Principal Subsidiary."

                  SECTION 12.       This First Supplemental Indenture shall
become effective upon its execution and delivery by the parties hereto.

trust created by the Indenture.

                  SECTION 15.       The Indenture, as hereby amended, is in all

                  SECTION 18.       In case any provision in this First
Supplemental Indenture is invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

                  SECTION 19.       If any provision of this First Supplemental
Indenture limits, qualifies or conflicts with any provision of the TIA that is
required under the TIA to be part of and govern the Indenture, such provision of
the TIA shall control. If any provision of this First Supplemental Indenture
