        12.

obligations or warranties described in Article 11(a), (b), and (c) herein:

        13.
Force Majeure. In the event that performance by either party of any of its obligations under the terms of this Agreement shall be interrupted by an act
of God, by an act of war, riot, or a civil disturbance, by an act of state, by strikes, fire, flood, hurricane, or by the occurrence of any other event beyond the reasonable control of either party
hereto, and which by the exercise of due diligence could not reasonably be prevented, such party shall be excused from such performance for an equal amount of time as such occurrence shall have
existed. In the further event that, during any period of Force Majeure the Rig, any part of the Rig or related equipment is damaged or destroyed in Seller's yard, the Seller bears all related expenses
pursuant to Article 18 of this Agreement. A party claiming an event of Force Majeure shall notify the other party in writing of such event and the anticipated duration of such event. The above

certifications which are not included or contemplated in this Agreement or (d) there is a delay in Purchaser furnished equipment, if any, not caused in whole or in part by Seller (collectively
"Permissible Delays" including "Rain Delays"). In addition, Seller shall have the time for any performance extended as a result of a Rain Delay, as hereinafter defined, for the same period of time
caused by any such Rain Delay. A Rain Delay is defined for purposes of this Agreement, as a delay caused by weather conditions which render the Work unsafe, impracticable, or unperformable in the
determination of the job superintendent and verified by the Purchaser. The Seller shall maintain a written log of the weather conditions which pertain to this issue and shall promptly provide the
Purchaser with written notice of any Rain Delay. Acceptance of any delays defined as Permissible Delays, including but not limited to Rain Delays, or Force Majeure shall not be unreasonably withheld
by the Purchaser. Notwithstanding anything herein to the contrary, all purchaser furnished equipment must be at Seller's facility no later than August 19, 2002.
