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:

6.3.3 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

7.4 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.
