TERM; TERMINATION The initial term of this Agreement shall be for 3 years (the "Initial Term") commencing on the date first set forth above (the "Commencement Date") and ending on the 3rd anniversary of the Commencement Date. This Agreement will automatically renew for successive one year terms (each a "Renewal Term", and together with the Initial Term, the "Term"), unless either Charterer or Owner elects not to renew this Agreement by providing the other party with written notice of such election 30 days prior to the expiration of the Initial Term or Renewal Term, as applicable, at which point this Agreement will automatically terminate. Within 30 days of the end of the Initial Term, and within 30 days of the end of each Renewal Term, both parties hereto shall have the right renegotiate the fee specified below for the use of the vessels. If no such agreement on such fee is reached by such parties by the commencement of a Renewal Term, this Agreement shall automatically terminate. Either party hereto shall have the right to terminate this Agreement in the event of a breach by the other party of its obligations hereunder, subject to 10 days prior written notice of such breach given by the non-breaching party to the breaching party and the opportunity for such breaching party to cure such breach during such 10 day period. Upon any such termination, this Agreement shall thereafter have no further force or effect except as to already accrued rights and obligations, which shall continue until satisfied. 2. GENERAL TERMS During the Term, Charterer agrees that Owner will be the sole and exclusive provider of marine transportation services for #2 fuel oil and high sulfur diesel owned by Charterer or owned by others and in transit for sale to Charterer so long as Owner has the required equipment available. Owner shall at all times provide sufficient and proper equipment for Charterer's performance of such transportation. Said equipment shall be manned, equipped, supplied and operated by Owner. The master and crew of said vessels shall be fully qualified, experience and, where necessary, certified and licensed. Owner agrees that said equipment shall be maintained in a seaworthy, staunch, tight and suitable condition and, to the best of Owner's knowledge, in compliance with all applicable laws and regulations. In connection with its use of any vessel, Charterer will follow Owner's normal scheduling, loading and offloading protocols established from time to time, subject to Owner's obligations set forth in this Agreement. 1 3.
