 NOW, in consideration of the premises and for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, IT IS HEREBY AGREED AS FOLLOWS: 
  

	 	1.	This Supplemental Agreement No. 5 (the “Agreement”) is supplemental to the CONTRACT and shall be considered an integral part thereof. Unless otherwise defined in this Supplemental Agreement
No. 5, words and expressions defined in the CONTRACT or Supplemental Agreement No. 1, Supplemental Agreement No. 2, Supplemental Agreement No. 3 or Supplemental Agreement No. 4 shall have the same meaning when used in this
Agreement. 








	 	2.	The obligations of the BUILDER and BUYER specified herein are subject to the payment by BUYER’s Affiliate, Alpha Archer Company, of One Hundred and Twenty Five Million United States Dollars (U$ 125,000,000) no
later than 15 December 2016 in respect of the construction of Hull No. 3622 that is the subject of that certain contract between Alpha Archer Company and the BUILDER dated 24 June 2013. 


 

	 	3.	BUILDER and BUYER agree to extend the DELIVERY DATE for the DRILLSHIP by an additional twenty four (24) months from the Fall 2017 Delivery Date (the “Revised Extension Period”) to 30 September
2019 (the “Fall 2019 Delivery Date”). Article VII.2.(a) of the CONTRACT shall be deleted in its entirety and shall be replaced with the following: 


The DRILLSHIP shall be DELIVERED safely afloat by BUILDER to BUYER at a berth in the SHIPYARD on or before 30th September 2019, except that, in the event of delays in the construction of the DRILLSHIP or any performance required under this CONTRACT due to causes which under the terms of this CONTRACT
permit postponement of the date for DELIVERY, the aforementioned date for DELIVERY of the DRILLSHIP shall be postponed accordingly. The aforementioned date, or such later date to which the requirement of DELIVERY is postponed pursuant to such terms,
is herein called the “DELIVERY DATE”. 
  

	 	4.	Notwithstanding the provisions of Article VII.2. of the CONTRACT (as amended by this Supplemental Agreement No. 5), at any time after the Effective Date of this Agreement but prior to 15 August 2019, BUYER may
give BUILDER written notice of its requirement that the DELIVERY DATE for the DRILLSHIP be accelerated to forty five (45) days from the date of such notice (the “Accelerated Delivery Notice – Fall 2019”). In the event an
Accelerated Delivery Notice – Fall 2019 is delivered, upon receipt of the Accelerated Delivery Notice – Fall 2019, BUILDER will promptly restart its construction and other activities and use its best efforts to deliver the DRILLSHIP within
the forty five (45) day period. In the event BUILDER fails to meet the accelerated DELIVERY DATE and deliver the DRILLSHIP within forty five (45) days from receipt of such notice, BUYER shall not be liable for the Extension Fee – Fall
2017 as specified in Supplemental Agreement No. 4, any interest accrued as specified in Section 6 or Section 8 of this Supplemental Agreement No.5, or for the Holding Costs specified in this Agreement for any day following the forty
five day period, in addition to remaining entitled to any other BUYER remedies provided in the CONTRACT. 

  

	 	5.	The BUYER and BUILDER agree to amend and revise the payment schedule for the DRILLSHIP, such that a new INTERIM PAYMENT 5 (“INTERIM PAYMENT 5”) shall be paid by BUYER to BUILDER in the amount of Ten
Million United States Dollars (USD $10,000,000) no later than the earlier of the ACTUAL DELIVERY DATE or 30 September 2017, provided, however, that INTERIM PAYMENT 5 shall not be made unless and until the BUILDER has completed all outstanding
punch list items to the reasonable satisfaction of BUYER, which shall be confirmed in writing between BUILDER and BUYER as soon as reasonably practicable following such completion. Any punch list items that BUILDER proposes to complete but the BUYER
requests to delay until immediately prior to the ACTUAL DELIVERY, with agreement on delay of any such items to be confirmed in writing following the Effective Date of this Agreement, shall no longer be considered outstanding punch list items in
relation to the withholding of payment of INTERIM PAYMENT 5. The Parties agree that the CONTRACT PRICE, which was reduced pursuant to Supplemental Agreement No. 1, Supplemental Agreement No. 2, Supplemental Agreement No. 3, and
Supplemental Agreement No. 4, shall be further reduced by INTERIM PAYMENT 5 such that PAYMENT MILESTONE 2, due at the DELIVERY DATE of the DRILLSHIP, shall be reduced to Eighty Three Million Nine Hundred Thousand US Dollars (USD
$83,900,000.00). Accordingly, Article II.3(b) of the CONTRACT shall be amended such that the phrase “Ninety Three Million Nine Hundred Thousand (USD $93,900,000.00)” shall be deleted in its entirety and replaced with “Eighty Three
Million Nine Hundred Thousand (USD $83,900,000.00)”. 








	 	6.	The BUYER and BUILDER agree to modify the payment schedule for the DRILLSHIP, such that, notwithstanding the terms in Article II(4)(b) of the CONTRACT, PAYMENT MILESTONE 2 (which, for clarity, as used herein shall
include any references to “MILESTONE PAYMENT 2” in Supplemental Agreement No. 1, Supplemental Agreement No. 2, Supplemental Agreement No. 3, and Supplemental Agreement No. 4) shall not be due on the DELIVERY DATE of the
DRILLSHIP. Instead, the balance of PAYMENT MILESTONE 2 shall be due and paid, along with certain other fees and interest, as follows: 

  

	 	a.	Commencing on 1 December 2016, and accruing for every day thereafter until the date of payment of INTERIM PAYMENT 5, an amount of interest equal to four and one half percent (4.5%) per annum on the outstanding
balance of PAYMENT MILESTONE 2 (“Milestone 2 Interest Amount – A”) shall accrue. 

  

	 	b.	Commencing on the date of payment of INTERIM PAYMENT 5, and accruing for every day thereafter until the ACTUAL DELIVERY DATE, an amount of interest equal to four and one half percent (4.5%) per annum on the
outstanding balance of PAYMENT MILESTONE 2 (“Milestone 2 Interest Amount – B”) shall accrue. 

  

	 	7.	Notwithstanding Article VII(3) of the CONTRACT, DELIVERY of the DRILLSHIP shall occur without full payment of the CONTRACT PRICE on the ACTUAL DELIVERY DATE with BUILDER fulfilling all obligations specified in the
CONTRACT related to the DRILLSHIP, including but not limited to Article VII, in exchange for: 

  

	 	a.	BUYER and BUILDER executing a promissory note (“Promissory Note”) in substantively identical form to the Promissory Note attached as Exhibit A to this Supplemental Agreement No. 5 effective as of
the ACTUAL DELIVERY DATE for the outstanding balance of PAYMENT MILESTONE 2 and Milestone 2 Interest Amount – A, and Milestone 2 Interest Amount – B as specified in Article 6(a)and 6(b) above. Such Promissory Note shall bear interest at
five percent (5%) per annum, and shall be due and payable on 30 December 2022, provided, however, that BUYER may pre-pay such Promissory Note in full or in part at any time prior to 31 December 2022 without premium or penalty;


  

	 	b.	BUYER shall grant to BUILDER a first preferred mortgage over the DRILLSHIP (“Security Interest”) in substantively identical form as the First Preferred Ship Mortgage attached as Exhibit B to this
Supplemental Agreement No. 5 effective as of the ACTUAL DELIVERY DATE. Such Security Interest shall be recorded as soon as reasonably practicable with the applicable registry of the Republic of the Marshall Islands, but in any event no longer
than fourteen (14) days from the ACTUAL DELIVERY DATE (or such later date to which the BUILDER consents), provided that the DRILLSHIP cannot depart the SHIPYARD until the recordation of such Security Interest is complete unless BUILDER
otherwise consents; and 

  

	 	c.	BUYER shall provide BUILDER with an assignment of insurance relating to the DRILLSHIP in substantively identical form as the Assignment of Insurances attached as Exhibit C to this Supplemental Agreement No. 5
effective as of the ACTUAL DELIVERY DATE. 

  

	 	8.	 Commencing 1 December 2016, BUYER shall cease to pay to BUILDER the costs and fees set forth in Article 5 of
Supplemental Agreement No. 4, and any such accrued and unpaid costs and fees up to and inclusive of 30 November 2016 shall be paid in full by BUYER to BUILDER per the terms of the CONTRACT. Commencing 1 December 2016, BUYER shall owe
to BUILDER certain accrued and deferred costs (“Holding Costs”) associated with the holding of the DRILLSHIP at BUILDER’s location as specified in the CONTRACT, including but not limited to Supplemental Agreement No. 4,
until the ACTUAL DELIVERY DATE. Notwithstanding Article 5 of Supplemental Agreement No. 4, the Holding Costs shall be accrued from 1 December 2016 until the ACTUAL DELIVERY DATE, and the Holding Costs shall accrue interest at










	 	
the rate of four and one half percent (4.5%) per annum. The total amount of the accrued Holding Costs plus the accrued interest on such Holding Costs shall be paid in full from BUYER to
BUILDER on the ACTUAL DELIVERY DATE of the DRILLSHIP. The Holding Costs shall be comprised of the items set forth in Article 5 of Supplemental Agreement No. 4, with the changes noted below to the following items: 


 

	 	a.	the Vessel Storage at Quay Fee as specified in item no.4 of Appendix 1 to Supplemental Agreement No. 4 shall be amended to Ten Thousand United States Dollars per day (USD $10,000/day), and the corresponding Remark

	 	d.	the Supplemental Dock Fee shall be deleted in its entirety, and shall no longer accrue effective 1 December 2016; and 

  

	 	e.	the Extension Fee – Fall 2017 shall be deleted in its entirety, and shall cease to be payable monthly effective 1 December 2016. 


 

	 	9.	The BUYER hereby covenants that from date of this Agreement until the ACTUAL DELIVERY DATE, it shall make reasonable efforts to not exercise its right to terminate the Contract (as amended, supplemented and varied from
time to time) in accordance with the provisions of Article X of the Contract (as amended, supplemented and varied from time to time). In addition, the BUYER and BUILDER agree that from the date and time of the commencement of the WARRANTY PERIOD,
the BUYER, notwithstanding the provisions of Article X Section 1 of the CONTRACT, shall not exercise its rights to terminate the CONTRACT unless one of the following events occurs: i) the DRILLSHIP is declared an actual, constructive, arranged,
or compromised total loss prior to ACTUAL DELIVERY DATE, ii) the BUILDER breaches a material obligation of the CONTRACT which materially affects the condition of the DRILLSHIP or the ability for BUILDER to deliver the DRILLSHIP with clear title per
Article VII Section 4(e) and such breach cannot be cured prior to, or otherwise results in more than a further thirty (30) day delay to any scheduled DELIVERY DATE, including but not limited to the DELIVERY DATE that has moved due to an
Accelerated Delivery Notice – Fall 2019 delivered by BUYER, (iii) the BUILDER voluntarily or involuntarily is made a party to any receivership, liquidation, or bankruptcy proceeding which cannot be cured prior to, or otherwise results in
more than a further 30 day delay to any scheduled DELIVERY DATE, including but not limited to the DELIVERY DATE that has moved due to an Accelerated Delivery Notice – Fall 2019, or such proceeding prevents BUILDER from executing the Security
Interest or otherwise prevents BUILDER from performing its obligations related to providing to the BUYER deferred financing of the outstanding amounts due under the CONTRACT, as amended and supplemented from time to time, or any third party holding
an interest in the BUILDER or DRILLSHIP acts to otherwise prevent the delivery of the DRILLSHIP. 

  

	 	10.	All the terms and conditions of the CONTRACT, Supplemental Agreement No. 1, Supplemental Agreement No. 2, Supplemental Agreement No. 3 and Supplemental Agreement No. 4 shall remain unchanged and be
in full force and effect unless otherwise provided hereunder. 








	 	11.	The existence and content of this Supplemental Agreement No. 5 shall remain strictly private and confidential to the Parties and their advisors and shall not be disclosed by either Party to any third party (except

	 	12.	Each Party hereto confirms that its respective obligations under, arising out of or in connection with, the CONTRACT shall continue in full force and effect as amended by this Supplemental Agreement No. 5.


  

	 	13.	This Supplemental Agreement No. 5 shall be governed by and construed in accordance with the laws of England and any dispute arising under this Supplemental Agreement No. 5 shall be submitted to arbitration in

the same instrument. Delivery of an executed signature page of this Supplemental Agreement No. 5 in Portable Document Format (PDF) or by facsimile transmission shall be effective as delivery of an executed original counterpart of this

 Exhibit A 

Form of Guaranty 






 GUARANTY 

GUARANTY, dated as of
                    , 20         (this “Guaranty”), by Atwood Oceanics Pacific
Limited, a company organized and existing under the laws of the Cayman Islands (“Guarantor”), in favor of Daewoo Shipbuilding & Marine Engineering Co., Ltd. (“Builder”). 

 

	1.	Guaranty. In connection with the entry into Supplemental Agreement No. 5 dated December [•], 2016 to the Drillship Contract dated September 27, 2012 (the “Supplement”), with Alpha
Admiral Company (“Buyer”), and to induce the Builder to extend credit pursuant to that certain Promissory Note, dated as of the date hereof (the “Promissory Note”), from Buyer to Builder, Guarantor hereby
absolutely, unconditionally and irrevocably guarantees to Builder and its successors and permitted assigns, the prompt payment and performance when due of all present and future obligations of Buyer to Builder arising out of the Promissory Note
(collectively, the “Obligations”). 

  

	2.	Nature of Guaranty. This is a guarantee of payment and performance and not collection. Guarantor agrees that Builder may look to Guarantor for payment and performance of any of the Obligations, whether or not
Builder shall have proceeded against Buyer with respect to any of the Obligations. Builder shall not be obligated to file any claim relating to the Obligations in the event that Buyer becomes subject to any bankruptcy, insolvency or similar
proceeding, and the failure of Builder to so file shall not affect Guarantor’s obligations hereunder. 

  

	3.	Changes in Obligations and Agreements Relating Thereto; Merger of Buyer; Waiver of Certain Notices and Rights. Guarantor agrees that Builder may at any time and from time to time, either before or after the
maturity thereof, without notice to or further consent of Guarantor, extend the time of payment or performance of, or renew any of the Obligations, and may also make any agreement with Buyer for the extension, renewal, payment, compromise, discharge
or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement between Builder and Buyer without in any way impairing or affecting this Guaranty. If Buyer merges or consolidates with or into another entity,
loses its separate legal identity or ceases to exist, Guarantor shall nonetheless continue to be liable for the Obligations. Guarantor waives (i) notice of the acceptance of this Guaranty and of the Obligations, (ii) all requirements as to
promptness, diligence, presentment, demand for payment, performance or otherwise, filing of claims, protest, notice of dishonor and notice of any kind with respect to this Guaranty, and (iii) any requirement that Builder exhausts any right or
take any action against Buyer, any collateral security or any other person or entity, or perfect its security interest in any collateral security. 

  

	4.	No Waiver; Cumulative Rights. No failure on the part of Builder to exercise, and no delay in exercising, any right, remedy or power hereunder shall operate as a waiver thereof, nor shall any single or partial
exercise by Builder of any right, remedy or power hereunder preclude any other or future exercise of any right, remedy or power. Each and every right, remedy and power hereby granted to Builder or allowed it by law or other agreement shall be
cumulative and not exclusive of any other, and may be exercised by Builder at any time or from time to time. 

  

	5.	Assignment. Neither this Guaranty nor any rights, interests or obligations hereunder may be assigned (except by operation of law), (i) in the case of the Guarantor, without the prior written consent of
Builder and (ii) in the case of the Builder, other than to an Affiliate (as defined in the Promissory Note) of the Builder.

 (b) The Shipowner shall promptly notify the Mortgagee of and furnish the
Mortgagee with full information, including copies of reports and surveys, regarding any material accident or accident involving repairs where the aggregate cost is likely to exceed Fifty Million United States Dollars (USD 50,000,000) (or its

 Section 1. Events of Default. Should an Event of Default occur pursuant to the terms thereof, such
event shall also, at the option of the Mortgagee, constitute an “Event of Default” hereunder. 
 Section 2. Consequences

irrespective of whether or not the Mortgagee has exercised the right of acceleration under the Note or any rights under the Guaranty and the Mortgagee shall have the right, to: 

(a) By notice in writing to the Shipowner, declare all the then unpaid Obligations to be due and payable immediately, and upon
such declaration, the same shall become and be immediately due and payable; provided, however, that no 

  
 6 







 
declaration shall be required if an event of default shall have occurred by reason of a default under Section 7(e) of the Note, then and in such case, the Obligations shall become
immediately due and payable on the occurrence of such event of default without any notice or demand; 
 (b) Exercise all of
the rights and remedies in foreclosure and otherwise given to mortgagees by the provisions of the laws of the Republic of the Marshall Islands or of any other jurisdiction where the Vessel may be found;

Shipowner shall surrender to the Mortgagee possession of the Vessel; 
 (e) The Mortgagee may hold, lay up, lease, charter,
operate or otherwise use the Vessel for such time and upon such terms as it may deem to be for its best advantage, and demand, collect and retain all day rates, hire, freights, earnings, issues, revenues, income, profits, return premiums, salvage
awards or recoveries, recoveries in general average, and all other sums due or to become due in respect of the Vessel or in respect of any insurance thereon from any person whomsoever, accounting only for the net profits, if any, arising from such
use of the Vessel and charging upon all receipts from the use of the Vessel or from the sale thereof by court proceedings or, pursuant to subsection (f) below, all reasonable and documents out-of-pocket costs, expenses, charges, damages or
losses by reason of such use; and if at any time the Mortgagee shall avail itself of the right herein given it to take the Vessel, the Mortgagee shall have the right to dock the Vessel, for a reasonable time at any dock, pier or other premises of
the Shipowner without charge, or to dock it at any other place at the cost and expense of the Shipowner; 
 (f) Take and
enter into possession of the Vessel, at any time, wherever the same may be, without legal process, and if it seems desirable to the Mortgagee and without being responsible for loss or damage, sell the Vessel, at any place and at such time as the
Mortgagee may specify and in such manner as the Mortgagee may deem advisable, free from any claim by the Shipowner in admiralty, in equity, at law or by statute, at public or private sale, by sealed bids or otherwise, by mailing, by air or
otherwise, notice of such sale, whether public or private, addressed to the Shipowner at its last known address, fourteen (14) days prior to the date fixed for entering into the contract of sale and by first publishing notice of any such public

 7 







 
may make any such sale at the time and place to which the same shall be so adjourned; and any sale may be conducted without bringing the Vessel to the place designated for such sale and in such

Section 3. Any sale of the Vessel made in pursuance of this Mortgage, whether under the power of sale hereby granted or any judicial
proceedings, shall operate to divest all right, title and interest of any nature whatsoever of the Shipowner therein and thereto, and shall bar the Shipowner, its successors and assigns, and all persons claiming by, through or under it. No purchaser
shall be bound to inquire whether notice has been given, or whether any default has occurred, or as to the propriety of the sale, or as to the application of the proceeds thereof. In case of any such sale, the Mortgagee, if it is the purchaser,
shall be entitled for the purpose of making settlement or payment for the property purchased to use and apply the Obligations in order that there may be credited against the amount remaining due and unpaid thereon the sums payable out of the net
proceeds of such sale to the Mortgagee after allowing for the costs and expense of sale and other charges; and thereupon such purchaser shall be credited, on account of such purchase price, with the net proceeds that shall have been so credited upon
the Obligations. At any such sale, the Mortgagee may bid for and purchase such property and upon compliance with the terms of sale may hold, retain and dispose of such property without further accountability therefor. 

Section 4. The Mortgagee is hereby irrevocably appointed attorney-in-fact of the Shipowner, during the continuation of any Event of
Default, to execute and deliver to any purchaser aforesaid, and is hereby vested with full power and authority to make, in the name and in behalf of the Shipowner, a good conveyance of the title to the Vessel so sold. In the event of any sale of the
Vessel, under any power herein contained, the Shipowner will, if and when required by the Mortgagee, execute such form of conveyance of the Vessel as the Mortgagee may direct or approve. 

Section 5. Whenever any right to enter and take possession of the Vessel accrues to the Mortgagee, it may require the Shipowner to
deliver, and the Shipowner shall on demand deliver to the Mortgagee the Vessel to a location designated by the Mortgagee as demanded. If the Mortgagee shall be entitled to take any legal proceedings to enforce any right under this Mortgage, the
Mortgagee shall be entitled as a matter of right to the appointment of a receiver of the Vessel and of the day rates, freights, hire, earnings, issues, revenues, income and profits due or to become due and arising from the operation thereof. 

  
 8 







 Section 6. During the continuation of any Event of Default, the Shipowner authorizes and
empowers the Mortgagee or its appointees or any of them to appear in the name of the Shipowner, its successors and assigns, in any court of any country or nation of the world where a suit is pending against the Vessel because of or on account of any
alleged lien against the Vessel from which the Vessel has not been released, and to take such proceedings as to them or any of them may seem proper towards the defense of such suit and the purchase or discharge of such lien, and all expenditures
made or incurred by them or any of them for the purpose of such defense or purchase or discharge shall be a debt due from the Shipowner, its successors and assigns, to the Mortgagee, and shall be secured by the lien of this Mortgage in like manner
and extent as if the amount and description thereof were written herein. 
 Section 7. The Shipowner covenants that upon the happening
of any Event of Default, then, upon written demand of the Mortgagee, the Shipowner will pay to the Mortgagee the whole amount due and payable in respect of the Obligations; and in case the Shipowner shall fail to pay the same forthwith upon such
demand, the Mortgagee shall be entitled to recover judgment for the whole amount so due and unpaid, together with such further amounts as shall be sufficient to cover the reasonable compensation to the Mortgagee’s agents, attorneys and counsel
and any necessary advances, expenses and liabilities made or incurred by it or the Mortgagee hereunder, in each case, as required by Section 9 of the Note. All moneys collected by the Mortgagee under this Article II, Section 7 shall be
applied by the Mortgagee in accordance with Article II, Section 11. 
 Section 8. Each and every power and remedy herein given to
the Mortgagee shall be cumulative and shall be in addition to every other power and remedy herein given or now or hereafter existing at law, in equity, in admiralty or by statute, and each and every power and remedy whether herein given or otherwise
existing may be exercised from time to time and as often and in such order as may be deemed expedient by the Mortgagee, and the exercise or the beginning of the exercise of any power or remedy shall not be construed to be a waiver of the right to
exercise at the same time or thereafter any other power or remedy. The Mortgagee shall not be required or bound to enforce any of its rights under the Note prior to enforcing its rights under this Mortgage. No delay or omission by the Mortgagee in
the exercise of any right or power or in the pursuance of any remedy accruing upon any Event of Default shall impair any such right, power or remedy or be construed to be a waiver of any such Event of Default or to be an acquiescence therein; nor
shall the acceptance by the Mortgagee of any security or of any payment of or on account of the Obligations maturing after any Event of Default or of any payment on account of any past Event of Default be construed to be a waiver of any right to
exercise its remedies due to any future Event of Default or of any past Event of Default not completely cured thereby. No consent, waiver or approval of the Mortgagee shall be deemed to be effective unless in writing and duly signed by authorized
signatories of the Mortgagee; any waiver by the Mortgagee of any of the terms of this Mortgage or any consent given under this Mortgage shall only be effective for the purpose and on the terms which it is given and shall be without prejudice to the
right to give or withhold consent in relation to future matters (which are either the same or different). 

  
 9 







 Section 9. If at any time after an Event of Default and prior to the actual sale of the
Collateral by the Mortgagee or prior to any enforcement or foreclosure proceedings, the Shipowner offers completely to cure all Events of Default and to pay all reasonable expenses, advances and damages to the Mortgagee consequent on such Events of
Default, then the Mortgagee must accept such offer and payment and restore the Shipowner to its former position, but such action, if taken, shall not affect any subsequent event of default or impair any rights consequent thereon. 

Section 10. In case the Mortgagee shall have proceeded to enforce any right, power or remedy under this Mortgage by foreclosure, entry or
otherwise, and such proceedings shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Mortgagee, then and in every such case the Shipowner and the Mortgagee shall be restored to their former
positions and rights hereunder with respect to the property subject or intended to be subject to this Mortgage, and all rights, remedies and powers of the Mortgagee shall continue as if no such proceedings had been taken. 

Section 11. (a) The proceeds of any sale of the Collateral and the net earnings of any charter operation or other use of the Vessel and
any and all other moneys received by the Mortgagee pursuant to or under the terms of this Mortgage or in any proceedings hereunder, the application of which has not elsewhere herein been specifically provided for, shall be applied: 

first, to the payment of all indemnities and expenses payable to the Mortgagee under the Notes and this Mortgage; 

second, to all accrued and unpaid interest on the principal of the Note; 

third, to the outstanding principal amount under the Note; and 

fourth, the balance, if any, to the Shipowner or such other Person as may be legally entitled thereto. 

(b) To the extent the proceeds of the sale of the Collateral are not sufficient to pay the aggregate amount of the Obligations,
the Shipowner shall remain liable for such deficiency. Without limiting the generality of the foregoing, the rights and remedies of the Mortgagee under this Mortgage and the other agreements, documents and instruments securing or guarantying any of
the Obligations shall be cumulative, and the exercise or partial exercise of any such right or remedy shall not preclude the exercise of any right or remedy. 

Section 12. Until one or more Events of Default shall happen and be continuing, the Shipowner (a) shall be suffered and permitted to
retain actual possession and use of the Collateral and (b) shall have the right, from time to time, in its discretion, and without application to this Mortgagee, and without obtaining a release thereof by the Mortgagee, to dispose of, free from
the lien hereof, any boilers, engines, machinery, masts, spars, sails, rigging, boats, anchors, chains, tackle, apparel, furniture, fittings or equipment or any other appurtenances of the Vessel that are no longer useful, necessary, profitable or
advantageous in the operation of the Vessel, promptly replacing the same (except to the extent that, individually or in the aggregate, any removal shall not materially diminish the value of the Vessel) by new boilers, engines, machinery, masts,
spars, sails, rigging, boats, anchors, chains, tackle, apparel, furniture, fittings, equipment, or other appurtenances of substantially equal value to the Shipowner, which shall forthwith become subject to the lien of this Mortgage as a preferred
mortgage thereon. 

  
 10 







 Section 13. (a) If any provision of this Mortgage should be deemed invalid or shall be
deemed to affect adversely the preferred status of this Mortgage under any applicable law, such provision shall cease to be a part of this Mortgage without affecting the remaining provisions, which shall remain in full force and effect. 

(b) In the event that the Note or this Mortgage, or any of the documents or instruments which may from time to time be
delivered hereunder or thereunder or any provision hereof or thereof shall be deemed invalidated by present or future law of any nation or by decision of any court, or if any third party shall fail or refuse to recognize any of the powers granted to
the Mortgagee hereunder when it is sought to exercise them, this shall not affect the validity or enforceability of all or any other parts of the Note or this Mortgage or such documents or instruments and, in any such case, the Shipowner covenants
and agrees that, on demand, it will execute and deliver such other and further agreements, documents and instruments and do such things as the Mortgagee may reasonably deem to be necessary to carry out the true intent of this Mortgage and the Note.

 (c) Anything herein to the contrary notwithstanding, it is intended that nothing herein shall waive the preferred status
of this Mortgage and that, if any provision or portion thereof herein shall be construed to waive the preferred status of this Mortgage, then such provision to such extent shall be void and of no effect. 

(d) In the event that the title, or ownership of the Vessel shall be requisitioned, purchased or taken by any government of any
country or any department, agency or representative thereof, pursuant to any present or future law, proclamation, decree order or otherwise, the lien of this Mortgage shall be deemed to attach to the claim for compensation therefor, and the
compensation, purchase or other taking of such title or ownership is hereby agreed to be payable to the Mortgagee who shall be entitled to receive the same and shall apply it as provided in Section 11(a) of this Article III. In the event of any
such requisition, purchase or taking, and the failure of the Mortgagee to receive proceeds as herein provided, the Shipowner shall promptly execute and deliver to the Mortgagee such documents, if any, as in the opinion of the Mortgagee may be
necessary or useful to facilitate or expedite the collection by the Mortgagee of such part of the compensation, purchase price, reimbursement or award as is payable to it hereunder. 

Section 14. In the event of any legal proceedings, the Shipowner accepts for itself and subsequent owners of the Vessel, irrespective of
domicile or residence, the nonexclusive jurisdiction of the Courts of the State of New York or the United States District Court of the Southern District Court of New York as venue with notice provided in the manner set forth in Section 14(b) of
the Note. 

  
 11

ALPHA ADMIRAL COMPANY 

ASSIGNMENT OF INSURANCES

1. ALPHA ADMIRAL COMPANY, a company organized and existing under the laws of the Cayman Islands (the “Assignor”), in
consideration of the Holder referred to therein entering into the transactions described in the Promissory Note (as defined below), and for Ten Dollars (USD 10.00) lawful money of the United States of America, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, as the owner of the whole of the Marshall Islands flag vessel ATWOOD ADMIRAL, Official No. [            ] (the
“Vessel”) has collaterally assigned and by this instrument does hereby collaterally assign and grants a security interest to DAEWOO SHIPBUILDING AND MARINE ENGINEERING CO., LTD., as Holder, and its successors and permitted assigns
(the “Assignee”), in and to, all right, title and interest of the Assignor under, in and to (i) all policies and contracts of insurance from time to time taken out by or on behalf of the Assignor insuring physical damage to the
Vessel, including but not limited to (1) hull and machinery (including hull interest insurance, increased value insurance and freight interest insurances, if any) and (2) war risk, (ii) all claims, returns of premium and other monies
and claims for monies due and to become due under said insurances or in respect of said insurances, (iii) all other rights of the Assignor under or in respect of said insurances and (iv) any proceeds of any of the foregoing (collectively,
the “Insurances”) and (v) any compensation paid or payable by a government entity for the requisition for title, confiscation or compulsory acquisition of the Vessel (“Requisition Compensation”). Terms used
herein and not otherwise defined herein shall be used as defined in the Promissory Note, dated as of the date hereof (as amended, amended and restated, modified or supplemented from time to time, the “Promissory Note”) from Assignor
to Assignee. 
 2. The Assignor has executed and delivered the Promissory Note, and the Assignor has granted the Assignee a First Preferred
Ship Mortgage (the “Mortgage”) on the Vessel to secure its obligations under the Promissory Note. This Assignment of Insurances (this “Assignment”) is given as security for all amounts due and to become due to the
Assignee under the Promissory Note (the “Obligations”). 
 3. It is expressly agreed that anything herein contained to the
contrary notwithstanding, the Assignor shall remain liable under the Insurances to perform all of the respective obligations assumed thereunder and the Assignee shall have no obligation or liability whatsoever under the Insurances by reason of or
arising out of this Assignment nor shall the Assignee be required or obligated in any manner to perform or fulfill any obligations of the Assignor under or pursuant to the Insurances or to make any payment or to make any inquiry as to the nature or
sufficiency of any payment received by it or to present or file any claim, or to take any other action to collect or enforce the payment of any amounts which may have been assigned to it or to which it may be entitled hereunder at any time or times.

 4. The Assignor does hereby constitute the Assignee, its successors and permitted assigns, the Assignor’s true and lawful attorney,
irrevocably, with full power (in the name of the 






 
Assignor or otherwise), upon the occurrence and continuance of an Event of Default or an Event of Loss, to ask, require, demand, receive compound and give acquittance for any and all monies and
claims for monies due and to become due under or arising out of the Insurances, to endorse any checks or other instruments or orders in connection therewith and to file any claims or to take any action or institute any proceedings which the Assignee
may deem to be necessary or advisable in the premises. 
 5. The Assignor hereby covenants and agrees to procure that notice of this
Assignment, substantially in the form of Schedule 1 attached hereto, shall be duly given to all underwriters, and that it shall request that there shall be duly endorsed upon all slips, cover notes, policies, certificates of entry or other
instruments issued or to be issued in connection with the Insurances assigned hereby, clauses as to loss payee as its interests may appear substantially in the form set out in Schedule 2 attached hereto or in the event of a material change from such
form, as the Assignee may consent to or approve in writing. In all cases, unless otherwise agreed to in writing by the Assignee, such slips, cover notes, notices, certificates of entry or other instruments shall show the Assignee as a loss payee as
its interests may appear and shall provide that there will be no recourse against the Assignee for payment of premiums, calls or assessments. 

6. (a) Any monies collected or received by the Assignee hereunder in respect of an Event of Loss shall be applied by the Assignee in the
manner provided in Article III, Section 11 of the Mortgage. 
 (b) Absent an Event of Loss, all moneys collected or received by the
Assignor pursuant to this Assignment (other than Requisition Compensation) shall be applied to the reimbursement for repair and/or replacement of damaged property of the Vessel and for other covered expenses under the Insurances. 

7. The Assignor does hereby warrant and represent that it has not assigned or pledged, and hereby covenants that, without the prior written
consent thereto of the Assignee, so long as this Assignment shall remain in effect, it will not assign or pledge the whole or any part of the right, title and interest hereby assigned to anyone other than the Assignee, its successors or assigns, and
it will not take or omit to take any action, the taking or omission of which might result in an alteration or impairment of the Insurances, of this Assignment or of any of the rights created by the Insurances or this Assignment; provided, however,
this clause shall not limit or prohibit in any way the Assignor from (i) naming other Persons as additional assureds under policies of Insurance as their interests may appear, but such claims shall at all times be subordinated to the interest
of the Assignee hereunder and consistent with the Loss Payable Clause attached as Schedule 2 hereto and (ii) assigning or pledging the whole or any part of the right, title and interest hereby assigned, to any other Person, so long as the liens
and interests of such other Person are subordinate to this Assignment. 
 8. All notices, requests, consents, demands, and other
communications provided for or permitted hereunder shall be in the manner provided in Section 12 of the Promissory Note and addressed as provided therein. 

  
 2 







 9. Any payments made pursuant to the terms hereof shall be made to the Assignee to such account
or accounts as may, from time to time be designated by the Assignee or as the Assignee may otherwise instruct. 
 10. Except as provided in
Section 11 of this Assignment, none of the terms and conditions of this Assignment may be changed, waived, modified or varied in any manner whatsoever without the prior written consent of the Assignor and the Assignee. 

11. (a) After the Termination Date (as defined below), this Assignment and the security interest created hereby shall automatically terminate,
and the Assignee, at the request and expense of the Assignor, will execute and deliver to the Assignor a proper instrument or instruments acknowledging the satisfaction and termination of this Assignment, and will duly release (without recourse and
without any representation or warranty) the Insurances as have not theretofore been released pursuant to this Assignment, together with any monies at the time held by the Assignee or any of its sub-agents
hereunder. As used in this Assignment, “Termination Date” shall mean (i) the date upon which the Obligations have been paid in full or (ii) the date upon which a permitted assignee of the Assignor enters into a new
Assignment pursuant to Section 13. 
 (b) At any time that the Assignor desires that the Assignee release the Insurances as provided in
Section 11(a) hereof, the Assignor shall deliver to the Assignee a certificate signed by an authorized officer of the Assignor stating that the release of the Insurances is permitted pursuant to such Section 11(a). 

12. (a) THIS ASSIGNMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS
OF THE STATE OF NEW YORK. 
 (b) IN THE EVENT OF ANY LEGAL ACTION OR PROCEEDINGS WITH RESPECT TO THIS ASSIGNMENT, THE PARTIES HERETO HEREBY
ACCEPT, IRRESPECTIVE OF DOMICILE OR RESIDENCE, THE NONEXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK OR THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT COURT OF NEW YORK AS VENUE WITH NOTICE PROVIDED IN THE MANNER SET FORTH
IN SECTION 14(B) OF THE NOTE. 
 13. The Assignor may transfer ownership of the Vessel to an Affiliate of Atwood Oceanics, Inc. provided
that (i) such Affiliate assumes the Obligations and assumes the Assignor’s obligations under this Assignment (or enters into a new Assignment) on terms and conditions acceptable to the Assignee and (ii) the assumption of this
Assignment (or the entry into a new Assignment) is evidenced by all filings required by the Uniform Commercial Code of the State of New York. 

14. This Assignment may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which
counterparts when executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. Delivery of an executed counterpart of this Assignment by facsimile transmission or by electronic mail in .pdf
form shall be as effective as delivery of a manually executed counterpart hereof.

 SCHEDULE 2 TO ASSIGNMENT OF INSURANCES 

LOSS PAYABLE CLAUSE 

Loss, if any, payable to DAEWOO SHIPBUILDING AND MARINE ENGINEERING CO., LTD. (the “Mortgagee”), for distribution by the
Mortgagee to itself and to ALPHA ADMIRAL COMPANY, as owner (the “Owner”), as their respective interests may appear, or order, except that, unless the underwriters have been notified by the Mortgagee that an Event of Default has
occurred, in the case of any loss involving any damage to the Vessel, the underwriters may pay directly for the repair, salvage, liability or other charges involved, or if the Owner or bareboat charterer of the Vessel shall have first fully repaired
the damage and paid the cost thereof, or discharged the liability or paid all of the salvage or other charges, then the underwriters may pay the Owner as reimbursement therefor; provided, however, that if such damage involves a loss in excess of
U.S.$50,000,000 or its equivalent, the underwriters shall not make such payment without first obtaining the written consent thereto of the Mortgagee (not to be unreasonably withheld, conditioned or delayed if no Event of Default exists and such
proceeds are to be used for the repair and/or replacement of damaged property and for other covered expenses). 
 In the event of an actual
or constructive total loss or a compromised or arranged total loss or requisition of title, all insurance payments therefor shall be paid to the Mortgagee, for distribution by it in accordance with the terms of the Marshall Islands First Preferred
Ship Mortgage relating to the Vessel.
