then the Contract Price shall be reduced by Four thousand United States Dollars (US$ 4,000) per each metric ton of the shortfall below 19,500 metric tons. 

  

	 	(b)	In the event that the actual Variable Load Capacity of the DRILLSHIP is more than 1,500 metric tons below the Guaranteed Variable Load Capacity of the DRILLSHIP, then
the BUYER may at its option reject the DRILLSHIP and rescind the Contract in accordance with the provisions of Paragraphs 2, 3 and 4 of Article X - RESCISSION BY BUYER hereof or accept the DRILLSHIP at a reduction in the Contract Price of Four

 ARTICLE IV - APPROVAL OF PLANS AND DRAWINGS AND INSPECTION DURING CONSTRUCTION 
  

	1.	Approval of Plans and Drawings: 

 Approved plans and drawings of the BUILDER’s HN. 1674 (including all amendments, additions, deletions and variations incorporated into the Specification up to the date of this Contract signing) shall be deemed to be approved by the
BUYER and shall be applied to the Drillship. 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. In the event that assignment, novation or resale occurs under the Article XIII and as a result, BUYER’s Supervisor is changed during the construction of the
DRILLSHIP, any and all matters determined by mutual agreement between the BUYER’s Supervisor and the BUILDER prior to the dispatch of a new Supervisor shall be accepted and complied by the new Supervisor. In case two or more Supervisors are
dispatched to the Shipyard and authorized to perform the supervision, each of them will form uniform opinions between them to keep the design and specifications so as not to adversely affect the Contract Price and Delivery of the DRILLSHIP. In the
event of any additional costs attributable to dispatch of two or more Supervisors due to resale, novation, charter or any other occurrence otherwise resulting from the BUYER side, such costs shall be solely borne by the BUYER and the BUYER shall
reimburse and hold harmless the BUILDER from any such costs and expenses. 
  

 17 









	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. 
  

	4.	Facilities: 

 The BUILDER shall
furnish the Supervisor and his assistant(s) with adequate office space and such other reasonable facilities according to the BUILDER’s practice at or in the immediate vicinity of the Shipyard as may be necessary to enable them to effectively
carry out their duties. The BUYER shall pay for all such facilities other than office space at the BUILDER’s normal rate of charge. 
  

 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, 
 (i) any employee, agent, contractor, or
subcontractor of BUILDER, or 
 (ii) any employee of any agent, contractor, or subcontractor of BUILDER, regardless of the basis
of such claims and even if such claims should arise out of the sole or concurrent fault or negligence of BUYER, or any employee, agent, contractor or subcontractor of BUYER. 
 Similarly, the BUYER agrees to fully protect, defend, indemnify and hold BUILDER 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, 
 (i) any employee, agent, contractor, or subcontractor of BUYER, or 
 (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 has the right to request the BUYER to replace the Supervisor who is deemed unsuitable and unsatisfactory for the proper progress
of the DRILLSHIP’s design, construction, building, launching, equipping, and completion. The BUYER shall investigate the situation by sending its representative(s) to the Shipyard if necessary, and if the BUYER considers that such
BUILDER’s request is justified, the BUYER shall effect such replacement as soon as conveniently possible. 
  

 20 









	7.	Delivery and Construction Schedule: 

 Attached hereto as Exhibit “3” is a tentative Delivery and Construction Schedule, and within one hundred and eighty (180) days after the date of this Contract, BUILDER shall deliver or cause to be delivered to BUYER a final
Delivery and Construction Schedule (herein, as from time to time amended with notice to the BUYER, referred to as the “Schedule”), prepared in reasonable detailed schedule and setting forth the estimated time table for the design,
construction, building, launching, equipping, testing and completion of the DRILLSHIP, it being understood that the Schedule may be used by BUYER for purposes of verifying and measuring the progress being made under the terms of this Contract. In
the event the actual progress of the construction of the DRILLSHIP is lagging behind the Schedule, the BUILDER shall issue a recovery plan to overcome such lagging so that the planned Delivery Date shall not be affected. 
 During the course of performance of this Contract the BUILDER shall submit to the BUYER on a monthly basis; 
  

	a)	a status report on the DRILLSHIP’s construction as compared with the Schedule; 

  

	b)	a report setting out the actual progress in performance of this Contract during the previous month as compared with the Schedule, including monthly progress photographs
illustrating the progress of the construction; 

  

	c)	a list of modifications or changes (if any) agreed during the previous month; 


	d)	a document register showing the status of document preparation and planned and actual completion of documents.

 ARTICLE V - MODIFICATIONS, CHANGES AND EXTRAS 
 1. How Effected: 
 The Specifications may be modified and/or changed by written
agreement of the parties, however, that any modifications and/or changes requested by the BUYER or an accumulation of such modifications and/or changes will not adversely affect the BUILDER’s planning or program in relation to the
BUILDER’s other commitments and if the BUYER shall assent to adjustment of the Contract Price, time for delivery of the DRILLSHIP, other terms and conditions of this Contract and the Specifications occasioned by or resulting from such
modifications and/or changes. The BUILDER hereby agrees to exert its best efforts to accommodate such reasonable request by the BUYER so that the said changes and/or modifications may be made at a reasonable cost and within the shortest period of
time that is reasonably possible. 
 Any such agreement for modifications and/or changes shall include an agreement as to the
increase or decrease, if any, in the Contract Price of the DRILLSHIP together with an agreement as to any extension or reduction in the time of delivery, or any other alterations in this Contract or the Specifications occasioned by such
modifications and/or changes. 
 The aforementioned agreement to modify and/or change the Specifications may be effected by an
exchange of letters signed by the authorized representatives of the parties hereto, or telefax confirmed in writing, manifesting such agreement. Such letters and confirmed message exchanged by the parties hereto pursuant to the foregoing shall
constitute an amendment of the Specifications, and such letters and message shall be incorporated into this Contract and made a part hereof. 
 The failure of the parties to agree on the increase or decrease in the Contract Price, or extension or reduction in the time of delivery, if any, for any modifications or changes requested by the BUYER
shall not prevent the BUILDER from performing any agreed work so as not to prevent the proper progress of the DRILLSHIP’s design, construction, building, launching, equipping, testing and completion, but shall be dealt with in accordance with
Article XII. 
  

 22 








 The BUILDER may make minor changes to the Specifications, if found necessary for
introduction of improved production methods or otherwise, provided that the BUILDER shall first obtain the BUYER’S approval that shall not be unreasonably withheld. 
  

	2.	Changes in Rules of Classification Society, Regulations, etc.: 

 If, after the Effective Date of this Contract, any requirements as to Classification Society, or as to the rules and regulations to which the construction of the DRILLSHIP is required to conform, are
altered or changed by the Classification Society or regulatory bodies authorized to make such alterations or changes, either of the parties hereto, upon receipt of information thereof, shall transmit such information in full to the other party in
writing within fourteen (14) days after receipt of the said information and thereafter the BUYER shall instruct the BUILDER in writing if such alterations or changes shall be made in the DRILLSHIP or not, in the BUYER’S sole discretion.

  

	 	(a)	However, if such alterations or changes are compulsory for the construction of DRILLSHIP, the BUILDER shall incorporate such alterations or changes into the
construction of the DRILLSHIP, provided that the parties shall agree on any increase or decrease in the Contract Price, extension or reduction in time of delivery of the DRILLSHIP and other terms and conditions of this Contract and the
Specifications occasioned by or resulting from such alterations or changes. 

  

	 	(b)	If such alterations or changes are not compulsory for the construction of the DRILLSHIP, but the BUYER desires to incorporate such alterations or changes into the
construction of the DRILLSHIP, then the BUYER shall notify the BUILDER in writing of such intention within fourteen (14) days after receipt of the said information. The BUILDER shall accept such alterations or changes, provided that the parties
shall agree on any increase or decrease in the Contract Price, extension or reduction in time of delivery of the DRILLSHIP and other terms and conditions of this Contract and the Specifications occasioned by or resulting from such alterations or
changes. 

 Such agreement of the BUYER shall be effected in the same manner as provided in Paragraph 1 of this
Article for modifications and/or changes of the Specifications. The failure of the parties to agree on the increase or decrease in the Contract Price, or extension or reduction in the time of delivery, if any, for any modifications or changes
requested by the BUYER shall not prevent the BUILDER from performing any agreed work so as not to prevent the proper progress of the DRILLSHIP’s design, construction, building, launching, equipping, testing and completion, but shall be dealt
with in accordance with Article XII. 
  

 23 









	3.	Substitution of Materials: 

 In
the event that any of the materials required by the Specifications or otherwise under this Contract for the construction of the DRILLSHIP can not be procured in time to effect timely delivery of the DRILLSHIP, or are in short supply, (other than as
the result of any neglect or omission on the part of the BUILDER) the BUILDER may, provided the BUYER so agrees in writing, supply other materials and equipment of the best available and like quality, capable of meeting the requirements of the
Classification Society and of the rules, regulations, requirements and recommendations with which the construction of the DRILLSHIP must comply. Any agreement as to such substitution of materials shall be effected in the manner as provided in
Paragraph 1 of this Article, and shall, likewise, include decrease or increase in the Contract Price and other terms and conditions of this Contract affected by such substitution. 
 (End of Article)

 ARTICLE VI - TRIALS AND ACCEPTANCE 
  

	1.	Notice: 

 The sea trial shall
start when the DRILLSHIP is reasonably completed in all material respects according to the Specifications, and otherwise any and all tests or trials shall be performed and notified as per the Specifications.

writing or by telefax confirmed in writing of the time and place of the sea trial of the DRILLSHIP, and the BUYER shall promptly acknowledge receipt of such notice. The BUYER shall have its representative and his assistant(s) on board the DRILLSHIP
to witness such sea trial. 
 Failure in attendance of the BUYER’S representative at the sea trial of the DRILLSHIP for any
reason whatsoever after due notice to the BUYER as above provided shall be deemed to be a waiver by the BUYER of its right to have its representative on board the DRILLSHIP at the sea trial, and the BUILDER may conduct the sea trial without
attendance of the BUYER’S representative, and in such case the BUYER shall be obligated to accept the DRILLSHIP on the basis of certificates of the Classification Society and a certificate of the BUILDER stating that the DRILLSHIP, upon sea
trial, is found to conform to this Contract and the Specifications. 
  

	2.	Weather Condition: 

 The sea
trial and any other tests and trials of the DRILLSHIP as per the Specifications shall be carried out under the weather condition that is deemed favorable enough by the judgment of both the BUYER and the BUILDER and as per the Specifications. In the
event of unfavorable weather on the date specified for the sea trial or other tests and trials as per the Specifications, the same shall take place on the first available day thereafter that the weather condition permits. It is agreed that, if
during the sea trial or other tests and trials of the DRILLSHIP as per the Specifications, the weather should suddenly become so unfavorable that orderly conduct of the test or trial can no longer be continued, the test or trial shall be
discontinued and postponed until the first favorable day next following, unless the BUYER shall assent in writing to acceptance of the DRILLSHIP on the basis of the tests and trials already made before such discontinuance has occurred. 

 

 25 








 Any delay of sea trial caused by such unfavorable weather condition shall operate to
postpone the Delivery Date by the period of the delay involved and such delay shall be deemed as permissible delay in the delivery of the DRILLSHIP. 
  

	3.	How Conducted: 

  

	 	(a)	The sea trial and any other tests and trials as per the Specifications shall be conducted in the manner prescribed in the Specifications, and shall prove full
fulfillment of the performance requirements for the trial run as set forth in the Specifications.

tests and trials under the BUILDER’S responsibility and risk and familiarized themselves with the system for the final take over of the Drillship. 

  

	4.	Method of Acceptance or Rejection. 

  

	 	(a)	Upon completion of the sea trial, the BUILDER shall give the BUYER a notice by telefax of completion of the trial run, as and if the BUILDER considers that the results
of trial run indicate conformity of the DRILLSHIP to this Contract and the Specifications. The BUYER shall, within Five (5) days after receipt of such notice from the BUILDER, notify the BUILDER by telefax of its acceptance or rejection of the
DRILLSHIP’s conformity to this Contract and Specifications. 

  

	 	(b)	However, if the result of the sea trial is unacceptable, or if the DRILLSHIP, or any part or equipment thereof, (except a defect in the BUYER’S supplies not being
the responsibility of the BUILDER) does not conform to the requirements of this Contract and/or the Specifications, or if the BUILDER is in agreement to non conformity as specified in the BUYER’S notice of rejection, then, the BUILDER shall
take necessary steps to correct such non-conformity. 

  

 26 








 Upon completion of correction of such non-conformity, and re-test or trial if necessary, the
BUILDER shall give the BUYER notice thereof by telefax confirmed in writing. 
 The BUYER shall, within Five (5) days after
receipt of such notice from the BUILDER, notify the BUILDER of its acceptance or rejection of the DRILLSHIP. 
  

	 	(c)	In the event that the BUYER rejects the DRILLSHIP, the BUYER shall indicate in detail in its notice of rejection in what respect the DRILLSHIP, or any part or equipment
thereof (except a defect in the BUYER’S supplies not the responsibility of the BUILDER) does not conform to this Contract and/or the Specifications. 

  

	 	(d)	In the event that the BUYER fails to notify the BUILDER by telefax confirmed in writing of the acceptance of or the rejection together with the reason therefore of the
DRILLSHIP within the period as provided in the above Sub-paragraph (a) or (b), the BUYER shall be deemed to have accepted the trial results and/or the DRILLSHIP, as appropriate. 

  

	 	(e)	Any dispute between the BUILDER and the BUYER as to the conformity or non conformity of the DRILLSHIP to the requirements of this Contract and/or the Specifications
shall be submitted for final decision in accordance with Article XII hereof. 

  

	 	(f)	The BUYER shall not be entitled to refuse acceptance of the DRILLSHIP by reason of any minor or insubstantial non-conformity with this Contract and the Specifications.
For the purpose of this Sub-paragraph, a minor or insubstantial non conformity shall mean a non-conformity that does not impair the safe or efficient operation of the DRILLSHIP and shall exclude any non-conformities affecting compliance with the
rules and regulations of the Classification Society and other relevant Regulatory Bodies of the DRILLSHIP as defined in the Specifications. 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. However, the BUYER’S acceptance of the DRILLSHIP shall not affect the BUYER’S rights under Article IX hereof. 
  

	6.	Disposition of Surplus Consumable Stores: 

 Any fuel oil furnished and paid for by the BUILDER for sea trial remaining on board including in systems and pipes of the DRILLSHIP, at the time of acceptance of the DRILLSHIP by the BUYER, shall be
bought by the BUYER from the BUILDER at the BUILDER’S purchase price for such supply in Korea and payment by the BUYER thereof shall be made at the time of delivery of the DRILLSHIP. 
 The BUILDER shall pay the BUYER at the time of delivery of the DRILLSHIP an amount for the consumed quantity during sea trial of any
lubricating oil and greases which were furnished and paid for by the BUYER, if any, at the BUYER’S purchase price thereof.

 ARTICLE VIII - DELAYS AND EXTENSION OF TIME FOR DELIVERY (FORCE MAJEURE) 
  

	1.	Causes of Delay (Force Majeure): 

 If, at any time either the construction or delivery of the DRILLSHIP or any performance required hereunder as a prerequisite to the delivery thereof is delayed by any of the following events; namely war, acts of state or government,
blockade, revolution, insurrections, mobilization, civil commotion, riots, strikes, sabotage, lockouts, Acts of God or the public enemy, plague or other epidemics, quarantines, prolonged failure of electric current, freight embargoes, or defects in
major forgings or castings, if any, or shortage of materials, machinery or equipment in inability to obtain delivery or delays in delivery of materials, machinery or equipment other than resulting from any act, omission or improvidence of the
BUILDER or its agents, employees or Subcontractors, provided that at the time of ordering the same could reasonably be expected by the BUILDER to be delivered in time, or defects in materials, machinery or equipment which could not have been
detected by the BUILDER using reasonable care, or earthquakes, tidal waves, typhoons, hurricanes, prolonged or unusually severe weather conditions or delay in the construction of the BUILDER’S other new-building projects in the same dry-dock
due to any such causes as described in this Article which in turn delay the keel laying and eventual delivery of the DRILLSHIP in view of the Shipyard’s overall building program or the BUILDER’S performance under this Contract, or by
destruction of the premises or works of the BUILDER or its sub-contractors, or of the DRILLSHIP, or any part thereof, by fire, landslides, flood, lightning, explosion, or other causes beyond the control of the BUILDER, or its sub-contractors, as the
case may be, or for any other causes which, under terms of this Contract, authorize and permit extension of the time for delivery of the DRILLSHIP, then, in the event of delays due to the happening of any of the aforementioned contingencies, the
Delivery Date of the DRILLSHIP under this Contract shall be extended for a period of time which shall not exceed the total accumulated time of all such delays. 
 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 Subcontractors, and that the BUILDER having taken all reasonable steps to mitigate the effect of the event upon the Delivery Date. 
  

 32 









	2.	Notice of Delay: 

 Within Ten
(10) days after the date of occurrence of any cause of delay, on account of which the BUILDER claims that it is entitled under this Contract to a postponement of the Delivery Date, the BUILDER shall notify the BUYER in writing or by telefax
confirmed in writing of the date when such cause of delay occurred. Likewise, within Ten (10) days after the date of ending of such cause of delay, the BUILDER shall notify the BUYER in writing or by telefax confirmed in writing of the date
when such cause of delay ended. 
 The BUILDER shall also notify promptly the BUYER of the period, by which in their opinion the
Delivery Date is postponed by reason of such cause of delay. If the BUILDER does not give the timely advice as above, the BUILDER shall lose the right to claim such delays as permissible delay. 
 Failure of the BUYER to acknowledge to the BUILDER’S claim for postponement of the Delivery Date within Ten (10) days after receipt
by the BUYER of such notice of claim shall be deemed to be a waiver by the BUYER of its right to object to such postponement of the Delivery Date. 
  

	3.	Definition of Permissible Delay: 

 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

 ARTICLE IX - WARRANTY OF QUALITY 
  

	1.	Guarantee: 

 The BUILDER, for the
period of Twelve (12) months after delivery of the DRILLSHIP (hereinafter called “Guarantee Period”), guarantees the DRILLSHIP and her engines, including all parts and equipment manufactured, furnished or installed by the BUILDER or
its subcontractors under this Contract, and including the machinery, equipment and appurtenances thereof (including the installation work performed or required to be performed by BUILDER under this Contract for the BUYER supplied or furnished
equipment), under the Contract but excluding any item which is supplied or designated by the BUYER or by any other bodies on behalf of the BUYER, against all defects discovered within the Guarantee Period which are due to defective material, design
and/or poor workmanship or negligent or other improper acts or omissions on the part of the BUILDER or its subcontractors (hereinafter called the “Defect” or “Defects”) and are not a result of accident, ordinary wear and tear,
misuse, mismanagement, negligent or other improper acts or omissions or neglect on the part of the BUYER, its employee or agents. 
  

	2.	Notice of Defects: 

 The BUYER
shall notify the BUILDER in writing, or by telefax confirmed in writing, of any Defect for which claim is made under this guarantee, as promptly as possible after discovery thereof. The BUYER’S written notice shall describe the nature, cause
and extent of the Defects. 
 The BUILDER shall have no obligation for any Defect discovered prior to the expiry date of the
Guarantee Period, unless notice of such Defect is received by the BUILDER not later than Fourteen (14) working days after the expiry of the Guarantee Period. 
  

	3.	Remedy of Defects: 

  

	 	(a)	The BUILDER shall remedy, at its expense, any Defect against which the DRILLSHIP is guaranteed under this Article, by making all necessary repairs or replacements at
the Shipyard. 

  

 35 









	 	(b)	However, if it is impracticable to bring the DRILLSHIP to the Shipyard, the BUYER may cause the necessary repairs or replacements to be made elsewhere which is deemed
suitable for the purpose, provided that, in such event, the BUILDER may forward or supply replacement parts or materials to the nearest airport or port from the DRILLSHIP, unless forwarding or supplying thereof would impair or delay the operation or
working schedule of the DRILLSHIP. In the event that the BUYER proposes to cause the necessary repairs or replacements for the DRILLSHIP to be made at any other shipyard or works than the Shipyard, the BUYER shall first, but in all events as soon as
possible, give the BUILDER notice in writing or by telefax confirmed in writing of the time and place when and where such repairs will be made, and if the DRILLSHIP is not thereby delayed, or her operation or working schedule is not thereby
impaired, the BUILDER shall have the right to verify by its own representative(s) the nature, cause and extent of the Defects complained of. The BUILDER shall, in such case, promptly advise the BUYER by telefax or telex after such examination has
been completed, of its acceptance or rejection of the Defects as ones that are covered by the guarantee herein provided. Upon the BUILDER’S acceptance of the Defects as justifying remedy under this Article, or upon award of the arbitration so
determining, the BUILDER shall compensate the BUYER for such repairs or replacements a sum equal to the necessary and reasonable cost of making the same repairs or replacements in a competent shipyard at a reasonable location, at the prices
prevailing at the time of such repairs or replacements are made. The reimbursement of the cost incurred in relation to guarantee works shall be paid after the repairs or replacements are made but if not made or the costs incurred for each such
repair or replacement is below US$ 100,000, such costs shall be paid at the expiration of the guarantee period. 

  

	 	(c)	The BUILDER guarantees repairs or replacements to the DRILLSHIP made under the guarantee in paragraph 1 of this Article for a further period of Twelve (12) months from
the date of completion of such repair or replacement. In any case, the maximum guarantee period shall not exceed Eighteen (18) months. 

  

	 	(d)	In any case, the DRILLSHIP shall be taken, at the BUYER’S cost and responsibility, to the place elected, ready in all respects for such repairs or replacement.


  

	 	(e)	Any dispute under this Article shall be referred to arbitration in accordance with the provisions of Article XII hereof. 

  

 36 









	4.	Extent of BUILDER’S Responsibility 

  

	 	(a)	The BUILDER shall have no responsibility or liability for any other defect whatsoever in the DRILLSHIP than the Defects specified in Paragraph 1 of this Article. Nor
the BUILDER shall in any circumstance be responsible or liable for any consequential or special loss, damage or expense including but not limited to loss of time, loss of profit of earning or demurrage directly or indirectly occasioned to the BUYER
by reason of the Defects specified in Paragraph 1 of this Article or due to repairs or other works done to the DRILLSHIP to remedy such Defects. 

  

	 	(b)	The BUILDER shall not be responsible for any defect in any part of the DRILLSHIP which may, subsequently to delivery of the DRILLSHIP, have been replaced or repaired in
any way by any other contractor, or for any defect which have been caused or aggravated by omission or improper use and maintenance of the DRILLSHIP on the part of the BUYER, its servants or agents or by ordinary wear and tear or by any other reason
beyond control of the BUILDER. 

  

	 	(c)	The guarantee contained as hereinabove in this Article replaces and excludes any other liability, guarantee, warranty and/or condition imposed or implied by the law,
customary, statutory or otherwise, by reason of the construction and sale of the DRILLSHIP by the BUILDER for and to the BUYER. 

 (End of Article) 
  

 37 








 ARTICLE X - RESCISSION BY BUYER 
  

	1.	Notice: 

 The payments made by
the BUYER prior to delivery of the DRILLSHIP shall be in the nature of advances to the BUILDER, and in the event that the DRILLSHIP is rejected by the BUYER or the Contract is rescinded by the BUYER in accordance with the terms of this Contract
under and pursuant to any of the provisions of this Contract specifically permitting the BUYER to do so, then the BUYER shall notify the BUILDER in writing or by telefax confirmed in writing, and such rescission shall be effective as of the date
when notice thereof is received by the BUILDER. 
  

	2.	Refundment by BUILDER: 

 In case
the BUILDER receives the notice stipulated in Paragraph 1 of this Article, the BUILDER shall promptly refund to the BUYER the full amount of all sums paid by the BUYER to the BUILDER on account of the DRILLSHIP, together with the interest thereon,
unless the BUILDER proceeds to the arbitration under the provisions of Article XII hereof. The BUILDER shall also return any BUYER’S Supplies, or if such cannot be returned, the BUILDER shall pay to the BUYER an amount equal to the BUYER’S
costs for such equipment. 
 In the event of such rescission by the BUYER, the BUILDER shall pay the BUYER interest at the rate
of six percent (6%) per annum on the amount required herein to be refunded to the BUYER, computed from the respective dates on which such sums were paid by the BUYER to the BUILDER to the date of remittance by transfer of such refund to the
BUYER by the BUILDER, provided, however, that if the said rescission by the BUYER is made under the provisions of Paragraph 4 of Article VIII hereof, then in such event the BUILDER shall pay the BUYER interest at the rate of four and a half percent
(4.5%) per annum on the sums refundable. 
 As security for refund of installments prior to delivery of the DRILLSHIP, the
BUILDER shall furnish to BUYER, prior to the due date of the first installment, with an irrevocable letter of guarantee covering the amount of such pre-delivery installments and issued by KEXIM, KDB, or a bank acceptable to the BUYER in favour of
the BUYER. Such letter of guarantee shall have substantially the same form and substance as Exhibit “4” annexed hereto. 
  

 38 









	3.	Discharge of Obligations: 

 Upon
such refund by the BUILDER to the BUYER, all obligations, duties and liabilities of each of the parties hereto to the other under this Contract shall be forthwith completely discharged, without prejudice, however, to any claims either party may have
resulting from the other party’s breach of any of its obligations under this Contract.

Refundment Guarantee or if any of the second, third or fourth installment is not paid in full by the BUYER to the BUILDER within Three (3) banking days in New York after such installment becomes due and payable as provided in Article II hereof;
or 

  

	 	(b)	If a performance guarantee by Cardiff Marine Inc. is not presented to the BUILDER within 5 banking days from the Effective Date of this Contract.


  

	 	(c)	If the fifth installment, after adjustment pursuant to the relevant provisions of this Contract, is not paid in full by the BUYER to the BUILDER concurrently with the
delivery of the DRILLSHIP as provided in Article II hereof; or 

  

	 	(d)	If the BUYER, when the DRILLSHIP is duly tendered for delivery by the BUILDER in accordance with the provisions of this Contract, fails to accept the DRILLSHIP within
Five (5) days from the tendered date without any specific and valid ground thereof under this Contract. 

  

	2.	Effect of Default on or before Delivery of DRILLSHIP: 

  

	 	(a)	Should the BUYER make default in payment of any installment of the Contract Price on or before delivery of the DRILLSHIP, the BUYER shall pay the installment(s) in
default plus accrued interest thereon at the rate of six percent (6%) per annum computed from the due date of such installment provided in Paragraph 4 of Article II hereof up to the date when the BUILDER receives the payment, and, for the
purpose of Paragraph 1 of Article VII hereof, the Delivery Date of the DRILLSHIP shall be automatically extended by a period of continuance of such default by the BUYER. 

 In any event of default by the BUYER, the BUYER shall also pay all charges and expenses incurred to the BUILDER in direct consequence of such
default. 
  

 40 









	 	(b)	If any default by the BUYER continues for a period of Fifteen (15) days, the BUILDER may, at its option, rescind this Contract by giving notice of such effect to
the BUYER by telefax confirmed in writing. 

 Upon dispatch by the BUILDER of such notice of rescission, this
Contract shall be forthwith rescinded and terminated. In the event of such rescission of this Contract, the BUILDER shall be entitled to retain any installment or installments already paid by the BUYER to the BUILDER on account of this Contract and
the BUYER’s Supplies already delivered to the Shipyard, if any. 
  

	3.	Disposal of DRILLSHIP: 

  

	 	(a)	In the event that this Contract is rescinded by the BUILDER under the provisions of Paragraph 2(b) of this Article, the BUILDER may, at its sole discretion, either

sole discretion and on such terms and conditions as the BUILDER shall deem fit. 

  

	 	(b)	In the event of such sale of the DRILLSHIP, the amount of the sale received by the BUILDER shall be applied firstly to all expenses attending such sale or otherwise
