(f)     The Seller shall, in each Contract Year, whether or not it has delivered the Minimum Volume, other than as a result of the breach by the Buyer of this Agreement or a Force Majeure Event, pay for an annual tonnage of the Product equal to the product of (i) the difference between (x) the Minimum Volume and (y) the number of tons of Product that the Seller has actually delivered that Contract Year multiplied by (ii) US$[***].

(e)     The Parties agree that the sums payable under this ‎Section 2.01 shall constitute liquidated damages and not penalties and are in addition to all other rights of the Parties under this Agreement.

The Buyer shall have the option to request an independent surveyor, in which case the Buyer shall bear the costs for such independent surveyor. Upon request from the Buyer, the Seller shall send to the Buyer the surveyor’s standard operating sampling procedures.

(b)     Such composite sample shall be split into three (3) sub samples of five (5) kilograms each, which shall be placed into suitable airtight and waterproof containers, sealed and signed by the surveyor.

(g)     In the event of a significant quality discrepancy, then the sample retained by the surveyor shall be sent to Construction Technology Lab Group for comparative testing and all costs related thereto shall be borne by the Party at fault of such discrepancy.

In the event that the Parties are unable to negotiate such price adjustment or find any other settlement during a negotiation period of thirty (30) days beginning on the day of receipt

In the event a conventional/open hatch vessel arrives to the Cartagena load port out of the previously agreed laycan between the Seller and the Buyer, the Seller shall confirm to the Buyer in writing the new date on which it may load the vessel, provided that it shall be the next possible and closest date to load, without causing the Seller to incur in extra costs due to this event. This paragraph shall not apply to the pneumatic vessels because their shipping schedules are based on the vessel’s consecutive voyage rotation.

In any case, either with a conventional/open hatch vessel or with a pneumatic vessel, the Seller commits with the Buyer to attend the vessel as early as possible and to give priority to such loadings.

Laytime shall cease to count when: (a) the loading of the cargo has been completely performed and the flow of Product has ceased, (b) after the loading equipment and labors have been removed from the vessel or (c) after the final draft survey has been performed, whichever occurs last.

The Seller and the Buyer will maintain confidential, and will cause their respective directors, officers, employees and affiliates to maintain confidential, all terms and conditions of this Agreement as well as any other confidential information exchanged between the Parties hereunder. In the case that any such confidential information is required to be delivered to a competent authority according to applicable laws and regulations, the Party who has been required to deliver such information to a competent authority shall promptly inform the other Party, in order for the other Party to cooperate in connection therewith and so that such other Party shall have an opportunity to seek an appropriate protective order or other appropriate remedy.

Section 8.15     Waivers and Consents. The failure of any Party to require strict performance by the other Party of any provision in this Agreement will not waive or diminish that Party’s right to demand strict performance thereafter of that or any other provision hereof. Any consent required or permitted to be given by any Party to the other Party under this Agreement shall be in writing and signed by the Party giving such consent.

Section 8.16     Third-Party Beneficiaries.

Article IX
DISPUTE RESOLUTION

Section 9.01     Negotiation. In the event of a controversy, dispute or claim arising out of, in connection with, or in relation to the interpretation, performance, nonperformance, validity or breach of this Agreement or otherwise arising out of, or in any way related to this Agreement or the transactions contemplated hereby, including any claim based on contract, tort, statute or constitution (individually and collectively, a “Dispute”), the Parties will utilize the dispute resolution processes set forth below to resolve any dispute, claim or controversy which the Parties have not been able to resolve to their mutual satisfaction in the ordinary course of business.

In the event the Parties are unable to resolve a Dispute in the ordinary course of business, either Party (the “Complaining Party”) may initiate the dispute resolution process by delivering written notice to the Coordination Committee members of the other Party (the “Receiving Party”). Within ten (10) business days after delivery of notice, the Receiving Party will submit to the Complaining Party a written response. Within five (5) business days after delivery of a response, the designated Coordination Committee members will meet and confer at a mutually acceptable time, and thereafter as often as they deem reasonably necessary, in an effort to resolve the Dispute through good faith negotiation.

Section 9.02     Jurisdiction and Service of Process.

(a)     If a Dispute has not been resolved to the mutual satisfaction of both Parties within twenty (20) business days following the Complaining Party’s delivery of the original notice, or if the Parties’ respective Coordination Committee members fail to meet and confer about the Dispute within fifteen (15) calendar days after delivery of the response (or such later date as the Parties may agree in writing), such Dispute will be subject to exclusive jurisdiction in the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or, if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any other state or federal court within the State of Delaware).

(b)     Process in any such action may be served on either Party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing,

each Party agrees that service of process on such Party as provided in Section 8.04 shall be deemed effective service of process on such Party.
