Whereas by a Shipbuilding Contract originally
dated 14 June 2013 in relation to Hull No. [*] – as amended – to which, by novation made on 8 July 2014, the
Builder, the Buyer and NCLC are parties – (the "Contract"), the Builder has agreed to design, build, complete and

with the terms and conditions of the Contract.


 


Whereas, the parties have agreed upon the
modification of Hull No. [*] basically like agreed before for Hull No. [*] but also with other modifications as further
stipulated in this Addendum No. 3.


 


Now, therefore, in consideration of the
premises, and for other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties
agree as follows:


 


		1.	The General Arrangement Plan and the Specification which are currently agreed by the parties within
the Contract and hence do currently form a part of the Contract shall be replaced as follows:

of doubt, this replacement shall in each case include any and all of the respective Appendices.

		7.	Speed



 


The trial speed of the Ship
at a mean moulded draft of 8.40 metres shall be at least 23.0 knots under the conditions specified in Section G.2.5 of the Specification.


 


		3.	Article 6, Clause 2.2 shall be amended as follows:



 


The guaranteed trial speed ("GTS")
of the Ship at a mean moulded draft of 8.40 metres (eight metres and fourty centimetres) shall be 23.0 knots and shall be demonstrated
by the Builder during the sea trials tests under the conditions described in section G.2.5 of the Specification. If at any time
the Builder anticipates that, or if the sea trials tests demonstrate that, there will be a deficiency in the GTS the Builder shall
promptly develop and provide the Buyer with a proposal to remedy the deficiency at the Builder's cost.


 


		4.	Article 6, Clause 2.6 shall be amended as follows:



 


The guaranteed deadweight capacity
of the Ship shall be eleven thousand seven hundred (11,700) metric tons under the conditions defined in sections G.2.3 and G.2.4
of the Specification and shall be demonstrated by the Builder in the specified deadweight capacity test.


 


		5.	The agreed price payable to the Builder for the modifications contemplated in this Addendum No.
3, including without limitation the new Specification and the new Plans, amounts to € [*] and shall – if not
agreed otherwise herein – be handled as an agreement on modification under and in accordance with Article 3 of the Contract
(the “[*] AOM”). The Buyer or NCLC shall pay the [*] AOM price to the Builder distributed on and in addition
to all outstanding next installments due and payable under and in accordance with the Contract in such a manner as described below:



 


		1.	[*] shall be paid with the second installment due and payable under and in accordance with
the Contract;



		2.	[*] shall be paid with the third installment due and payable under and in accordance with
the Contract;



		3.	[*] shall be paid with the fourth installment due and payable under and in accordance with
the Contract and



		4.	[*] shall be paid with the delivery installment (i.e. balance of the contract price) due
and payable under and in accordance with the Contract.



 


		6.	Currently the Builder’s Hull No. [*] is a) the First Ship as defined in Article 14,
Cl. 15.1 of the Contract and b) the reference ship as defined in Schedule 1 of the Contract. Upon execution of this Addendum No.
3 the Builder’s Hull Number [*] shall without any further notice be replaced with Builder’s Hull No. [*]
so that Builder’s Hull No. [*] shall from the date of execution of this Addendum No. 3 be the First Ship and the reference
ship under and in accordance with the Contract. In each case – prior to and after execution of this Addendum No. 3 –
the plans, drawings and other documents (including calculations,



 




    	 	 	Page 4 of 6



     


    

 


			investigations and tests) which have been agreed for the First Ship shall be deemed accepted for
the Ship, save and except where such plans, drawings and other documents (including calculations, investigations and tests) need
to be modified / redrawn to take account of differences between the First Ship and the Ship arising by virtue of AOMs in accordance
with Article 3 of the Contract.



 


		7.	For the avoidance of doubt, the Buyer and NCLC herewith agree that the CR&Es which are defined
as not included in this Addendum No. 3 according to Appendix No. 13 to the Specification are not part of the Contract – neither
in technical respects nor in commercial respects. Hence Article 3 of the Contract finds nevertheless application for these items
so that for these items the total sum shall be paid with the delivery installment (i.e. balance of Contract Price) due and payable
under and in accordance with the Contract. Furthermore the Buyer and NCLC herewith agree that all credits resulting e.g. (without
limitation) from any CR&Es and from any AOMs which have been agreed prior to the execution of this Addendum No. 3 are already
included in the [*] AOM price. Hence, the Buyer and NCLC cannot claim any such credits as being payable since the credits
have already been considered by the Builder for the benefit of the Buyer. For the avoidance of doubt, any and all CR&Es and
any and all AOMs which will be concluded after execution of this Addendum No. 3 shall be dealt with under and in accordance with
Article 3 of the Contract so that the contractually defined approach shall apply insofar.



 


		8.	This Addendum No. 3 will be treated as having been signed by the parties hereto at the time and
on the date when each party has signed and initialled a complete, legible and identical counterpart of this Addendum No. 3 and
exchanged the same by e-mail or fax with the other parties. Thereafter for record purposes only three identical original counterparts
of this Addendum No. 3 shall be signed and initialled by each of the parties after which one original counterpart will be retained
by the Builder, one will be retained by the Buyer and the other will be retained by NCLC.



 


		9.	Words and expressions defined in the Contract shall have the same meanings when used herein.



 


		10.	Except as set forth in this Addendum No. 3, the Contract shall remain unchanged and this Addendum
No. 3 shall be treated as an integral part of the Contract.
