                                         that vessel already paid by that Owner under this Agreement.

                                         or removed from Annex A in accordance with the terms of this clause 4 or otherwise, the

		6.	Charter
                                         allocation



 


		6.1	The Vessel Manager acknowledges that
                                         from time to time during this Agreement Blue Net may act as charter broker to vessels
                                         other than the Costamare Vessels.



 


		6.2	Blue Net hereby agrees and undertakes
                                         to the Vessel Manager (as agent for the Owners) that when a Costamare Vessel is, or is
                                         to be, released from any Charter, Blue Net will act equitably when deciding whether to
                                         allocate to that Costamare Vessel any charter available at the time for a vessel like
                                         that Costamare Vessel.



 


		6.3	In acting equitably pursuant to clause
                                         6.2 in allocating a charter to the most appropriate vessel it acts as charter broker
                                         for, Blue Net shall take into account which of the vessels it acts as charter broker
                                         for is, among others:



 


		6.3.1	without employment the longest;



 


		6.3.2	meeting the required specification best;
                                         and/or



 


		6.3.3	geographically closest to the delivery
                                         place.



 


		6.4	Notwithstanding clauses 6.2 and 6.3,
                                         Blue Net hereby undertakes to the Vessel Manager (as agent for the Owners) that if on
                                         expiry of a Charter for a Costamare Vessel the relevant charterer goes into the market
                                         for a similar vessel, Blue Net should reoffer to that charterer the same Costamare Vessel
                                         and no other vessel for which it may be acting as a charter broker at the time.



 


		7.	Final
                                         Provisions



 


		7.1	No collateral agreements have been concluded.
                                         Alterations and supplements to this Agreement must be made in writing. This Agreement
                                         can be signed in counterparts which together will constitute one instrument.



 


		7.2	This Agreement cannot be assigned or
                                         transferred by either Party without the other Party’s prior written consent. Blue
                                         Net cannot subcontract any of the services to be performed by it under this Agreement,
                                         without the prior written consent of the Vessel Manager.



 


		7.3	Venue for all disputes arising from
                                         and with connection to this Agreement is Hamburg, Germany, unless otherwise compulsory
                                         stipulated.

		7.4	This Agreement is governed by German
                                         law to the exclusion of conflict rules (Kollisionsnormen). This Agreement is made
                                         in the English language. Terms to which a German term has been added shall be interpreted
                                         throughout this Agreement in the meaning assigned to them by the German translation.



 


		7.5	Should a provision of this Agreement
                                         or a provision later on included in this Agreement be or become null and void as a whole
                                         or in part, or should a gap in this Agreement become evident, this does not affect the
                                         validity of the remaining provisions. Instead of the null and void provision, or in order
                                         to fill the gap, such valid and practicable regulation is deemed to be agreed with effect
                                         ex tunc which in legal and economic terms comes closest to what the Parties intended
                                         or would have intended in accordance with the purpose of this Agreement if they had considered
                                         the point at the time of conclusion of this Agreement. If the nullity of a provision
                                         is due to a measure of performance or time (period or deadline) laid down in this provision,
                                         then the provision is deemed to be agreed with a legally permissible measure which comes
                                         closest to the original measure.
