The BUILDER shall be exempted from the approval of the BUYER for the plans and drawings in accordance with the Specifications. All plans and drawings, which are modified by the BUILDER shall, however, be subject to approval by the BUYER in accordance with Article V.

2.	Appointment of BUYER’s Supervisor:

The BUYER may send to and maintain at the Shipyard, at the BUYER’s own cost and expense, one supervisor (herein called the “Supervisor”) who shall be duly authorized in writing by the BUYER, which authorization shall be described in a separate letter to be sent to the BUILDER prior to the Supervisor’s arrival, to act on behalf of the BUYER in connection with the modifications of the Specifications, adjustments of the Contract Price and Delivery Date in writing, approval of the plans and drawings, attendance to the tests and inspections relating to the DRILLSHIP, its machinery, equipment and outfittings, and any other matters for which he is specifically authorized by the BUYER. The Supervisor may appoint assistant(s) to attend at the Shipyard for the purposes as aforesaid.

3.	Inspection by the Supervisor:

The necessary inspections of the DRILLSHIP, its machinery, equipment and outfittings shall be carried out by the Classification Society, other regulatory bodies and/or the Supervisor throughout the entire period of construction in order to ensure that the design, construction, building, launching, equipping, testing and completion of the DRILLSHIP is duly performed in accordance with the Contract and the Specifications.

The BUILDER shall give a written notice to the Supervisors reasonably in advance of the date and place of tests and inspections for the convenience of their attendance. Failure of the Supervisors to be present at such tests and inspections after due notice to them as above provided, shall be deemed to be a waiver of their right to be present. In such cases, the BUYER shall be obliged to accept the results of such tests and inspections on the basis of the BUILDER’s certificate subject to acceptance by the Classification Society.

Whether or not the Supervisors have been present, the BUILDER shall promptly deliver to the BUYER or the Supervisors a copy of the results of all tests and inspections.

For tests or inspections outside the Shipyard sufficient advance notice to allow for the Supervisor to arrange transportation shall be given. This advance notice should not be less than three (3) days for tests or inspection that require air travel for attendance.

The inspection schedule must be reasonable at all times in order to allow the Supervisor to carry out their duties properly and inspections must be spread over reasonable time, but in follow building schedule at the same rate.

BUILDER may request BUYER’s Supervisor to attend the inspection and tests during public holidays and weekends and/or Company holidays in order to keep BUILDER’s construction schedule. BUYER’s Supervisor shall fully cooperate with BUILDER and promptly attend such inspection/tests including those for surface preparation and painting work, which are especially vulnerable to weather condition and time interval. However, BUILDER shall keep such inspection and tests to a minimum and only when the inspection and tests affect BUILDER’s construction schedule. The BUILDER’s prior notice of such inspection/test schedule shall be informed to the BUYER’s Supervisor one (1) day in advance as a minimum.

18

If any of the BUYER’s Supervisors discover any construction, material or workmanship which is not deemed to conform to the requirements of this Contract and/or the Specifications, the BUYER’s Supervisors shall promptly give the BUILDER a notice in writing that such alleged non-conformity exists. Upon receipt of such notice from the BUYER’s Supervisor, the BUILDER shall correct such non-conformity, if the BUILDER agrees to his view. Any disagreement shall be resolved in accordance with Paragraph 1 of Article XII and shall to the extent possible not prevent the progress of the construction and the timely delivery of the DRILLSHIP.

If, following such disagreement, the Classification Society or the arbitrator enters a determination in favor of the BUYER, then in such case the BUILDER shall immediately correct such non-conformity subject to Article VI 4. (b). If the Classification Society or the arbitrator enters a determination in favor of the BUILDER, then the time for delivery of the DRILLSHIP shall be extended for the period of any actual delay in construction, if any, occasioned by such proceedings (but not by any time by which the period is extended owing to the BUILDER’s own default), and the BUYER shall pay the BUILDER interest at the rate of five percent (5%) per annum on the outstanding Instalments of the Contract Price for the said period of delay.

In working hours during construction of the DRILLSHIP until delivery thereof, the BUYER’s Supervisors shall, subject to the reasonable requirements of the Shipyard’s work program and safety control, be permitted free and ready access to the DRILLSHIP, her machinery and equipment, and to any other place where work on the DRILLSHIP is being done, or materials are being processed or stored in connection with the construction of the DRILLSHIP, including the yards, workshops, stores and offices of the BUILDER, and the premises of subcontractors of the BUILDER, who are doing work or storing materials in connection with the DRILLSHIP’s construction.

19

5.	Liability of BUILDER:

The BUILDER agrees to fully protect, defend, indemnify and hold BUYER harmless from and against all liabilities, obligations, claims or actions for personal injury or death arising out of performance by BUILDER or BUYER of their obligations hereunder prior to the acceptance by BUYER of the DRILLSHIP, and asserted by or on behalf of,

(ii)

any employee of any agent, contractor, or subcontractor of BUYER, regardless of the basis of such claims and even if such claims should arise out of the sole or concurrent fault or negligence of BUILDER, or any employee, agent or subcontractor of BUILDER.

6.	Responsibility of BUYER:

The BUYER shall undertake and assure that the Supervisor shall carry out his duties hereunder in accordance with the normal shipbuilding practice of the BUILDER, which BUILDER represents and confirms is in all material respects in accordance with normal shipbuilding practice and in such a way so as to avoid any unnecessary increase in building cost, delay in the construction of the DRILLSHIP, and/or any disturbance in the construction schedule of the BUILDER.

The BUILDER shall remain obliged to correct and/or remedy such minor or insubstantial non-conformities as soon as reasonably possible following delivery of the DRILLSHIP.

5.	Effect of Acceptance:

Acceptance of the DRILLSHIP as above provided shall be final and binding so far as conformity of the DRILLSHIP to this Contract and the Specifications is concerned and

27

shall preclude the BUYER from refusing formal delivery of the DRILLSHIP as hereinafter provided, if the BUILDER complies with all other procedural requirements for delivery as provided in Article VII hereof.

The BUILDER’s entitlement to extension of the Delivery Date due to any of the aforesaid events shall, however, always be subject to the delay, or any part of the delay, not being caused by the BUILDER’s error, neglect, act or omission or that of its agents, employees or Subcontactors, and that the BUILDER having taken all reasonable steps to mitigate the effect of the event upon the Delivery Date.

Delays on account of such causes as specified in Paragraph 1 of this Article and any other delay of a nature which under the terms of this Contract permits postponement of the Delivery Date shall be understood to be permissible delays and are to be distinguished from unauthorized delays on account of which the Contract Price is subject to adjustment as provided for in Article III hereof.

We hereby open our irrevocable letter of guarantee No. in favor of Drillship Paros Owners Inc.

(hereinafter called the “BUILDER”) for the construction of one (1) Drillship composed of hull part and topside part, having BUILDER’S Hull No.1838 (hereinafter called the “DRILLSHIP”).

If in connection with the terms of the Contract the BUYER shall become entitled to a refund of the advance payment(s) made to the BUILDER prior to the delivery of the DRILLSHIP, we hereby irrevocably guarantee as primary obligor and not merely as surety the repayment of the same to the BUYER immediately on demand USD 91,105,500 (Say United States Dollars Ninety One Million One Hundred Five Thousand Five Hundred only) together with interest thereon at the rate of six percent (6%) per annum from the date following the date of receipt by the BUILDER to the date of remittance by telegraphic transfer of such refund.

The amount of this guarantee will be automatically increased, not more than three (3) times, upon BUILDER’S receipt of the respective installment: each time by the amount of instalment of USD 91,105,500, USD 91,105,500 and USD 91,105,500 respectively, plus interest thereon as provided in the Contract, but in any eventuality the amount of this guarantee shall not exceed the total sum of USD 364,422,000 (Say United States Dollars Three Hundred Sixty Four Million Four Hundred Twenty Two Thousand only) plus interest thereon at the rate of six per cent (6%) per annum from the date following the date of BUILDER’S receipt of each installment to the date of remittance by telegraphic transfer of the refund.

In case any refund is made to you by the BUILDER or by us under this guarantee, our liability hereunder shall be automatically reduced by the amount of such refund.

In the event of cancellation of the Contract being based on delays due to force majeure or other causes beyond the control of the BUILDER, as required by Article X of the Contract, interest shall be paid at the rate of Four and a half percent (4.5%) per annum from the date of following the date of Builder’s receipt of each installment to the date of remittance by telegraphic transfer of the refund.

This letter of guarantee is available against BUYER’S simple receipt and signed statement certifying that BUYER’S demand for refund has been made in conformity with Article X of the Contract and the BUILDER has failed to make the refund within Thirty (30) days after your demand to the BUILDER. Refund shall be made to you by telegraphic transfer in United States Dollars in freely transferable funds and free and clear of and without deduction for and on account of any set off, counterclaim or present or future tax, levy, impost, duty, charge, fee or other withholding of any nature whatsoever imposed and by whomsoever on yourselves. In the event we are required by law to make any deduction or withholding from any payment to be made by it pursuant to this letter of guarantee, we will pay to you whatever additional amount (after taking into account any additional taxes on, or deductions or withholdings from, or restrictions or conditions on, that additional amount) is necessary to ensure that, after making the deduction or withholding, you receive a net sum equal to the sum which you would have received had no deduction or withholding been made.

This letter of guarantee shall expire and become null and void upon receipt by the BUYER of the sum guaranteed hereby or upon acceptance by the BUYER of delivery of the DRILLSHIP in accordance with the terms of the Contract and, in either case, this letter of guarantee shall be returned to us. This guarantee is valid from the date of this letter of guarantee until delivery or in the event of delayed delivery until such time as the DRILLSHIP is delivered by the BUILDER to the BUYER in accordance with the terms of the Contract.

Notwithstanding the provisions hereinabove, in case we receive notification from you or the BUILDER confirmed by the Arbitration Board stating that your claim to cancel the Contract or your claim for refundment thereunder has been disputed and referred to Arbitration in accordance with the provisions of the Contract, the period of validity of this guarantee shall be extended until Sixty (60) days after the final award shall be rendered in the Arbitration and a copy thereof acknowledged by the Arbitration Board. In such case, this guarantee shall not be available unless and until such acknowledged copy of the final award in the Arbitration justifying your claim is presented to us.

This guarantee shall not be affected by any extension of time or concession granted by the BUYER to the BUILDER or any delay or failure of the BUYER in enforcing its rights under the Contract.

The BUYER shall have the right to assign this guarantee and all of its benefits to any assignee to whom the Contract is assigned.
