In addition, CIL or MLI may, upon notice to the other by telephone (confirmed promptly by telecopy or email, which confirmation will be promptly acknowledged), suspend the offering of the Shares for any reason and at any time; provided , however , that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Shares sold hereunder prior to the giving of such notice.

(b) MLI will indemnify and hold harmless CIL, the Company and Carnival Corp against any losses, claims, damages or liabilities to which CIL, the Company or Carnival Corp may become subject, under the Act or otherwise, insofar as such losses,

20

claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus Supplement or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Prospectus Supplement or the Prospectus, or any such amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by MLI expressly for use therein; and will reimburse CIL, the Company or Carnival Corp, as applicable, for any legal or other expenses reasonably incurred by CIL, the Company or Carnival Corp in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection except and then only to the extent such indemnifying party is materially prejudiced thereby. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory in the reasonable judgment of such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 7 for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party. No indemnifying party shall be liable for any settlement or compromise of or consent to the entry of judgment with respect to any such action or claim effected without its consent (which consent shall not be unreasonably withheld).

(d) If the indemnification provided for in this Section 7 is unavailable to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received

21

by CIL, the Company and Carnival Corp on the one hand and MLI on the other from the offering of the Shares to which such loss, claim, damage or liability (or action in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by CIL, such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of CIL, the Company and Carnival Corp on the one hand and MLI on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by CIL, the Company and Carnival Corp on the one hand and MLI on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by CIL bear to the total commissions received by MLI. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by CIL, the Company or Carnival Corp on the one hand or MLI on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. CIL, the Company, Carnival Corp and MLI each agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), MLI shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares sold by it to the public were offered to the public exceeds the amount of any damages which MLI has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The obligations of CIL, the Company and Carnival Corp under this Section 7 shall be in addition to any liability which CIL, the Company and Carnival Corp may otherwise have and shall extend, upon the same terms and conditions, to the directors and officers of MLI and to each person, if any, who controls MLI within the meaning of the Act and each broker dealer affiliate of MLI; and the obligations of MLI under this Section 7 shall be in addition to any liability which MLI may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of CIL, the Company and Carnival Corp and to each person, if any, who controls CIL, the Company or Carnival Corp within the meaning of the Act.

The respective indemnities, agreements, representations, warranties and other statements of each of CIL, the Company, Carnival Corp and MLI, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of MLI or any controlling person of MLI, or CIL, the Company or Carnival Corp or any officer or director or controlling person of CIL, the Company or Carnival Corp, and shall survive delivery of and payment for the Shares.
