of Indenture (this “Satisfaction of Indenture”), dated as of March 28, 2013, is entered into by and between Offshore Group Investment Limited, a Cayman Islands exempted company (the “Company”),
and Wells Fargo Bank, National Association (the “Trustee”). 
 Reference is made to the Indenture dated

and the Trustee, as trustee, noteholder collateral agent, paying agent and registrar. Capitalized terms not defined herein have the meanings given to them in the Indenture. 
 RECITALS 
 WHEREAS, the Indenture provided for the
issuance by the Company of
11 1/2 % Senior Secured First Lien Notes due 2015 (the “Notes”); 
 WHEREAS, pursuant to Section 3.07(c) of the Indenture, the Company elected to redeem the Notes in full on April 29, 2013 (“Redemption Date”) at the redemption price (expressed
as a percentage of principal amount) of 108.625% (the “Redemption Price”), plus accrued and unpaid interest on the Notes redeemed to, but not including, the Redemption Date (the “Redemption”); 

WHEREAS, in connection with the Redemption, the Company (i) authorized and directed the Trustee to send a notice of redemption to
the holders of all outstanding Notes under the Indenture; (ii) irrevocably deposited with the Trustee, in trust, solely for the benefit of the holders of such outstanding Notes, cash in U.S. dollars in an amount as is sufficient to pay and
discharge the entire outstanding Indebtedness on the Notes to the Redemption Date; and (iii) delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes on the Redemption Date; 

WHEREAS, in compliance with Section 10.01 of the Indenture, the Company delivered to the Trustee an Officers’ Certificate and
an Opinion of Counsel to the Trustee stating that all conditions precedent to the satisfaction and discharge of the Indenture and the release of the assets included in the Collateral securing the obligations under the Indenture have been satisfied;

 WHEREAS, the Company requested that the Trustee execute proper instruments acknowledging satisfaction of and discharge of the
Indenture, including, without limitation, this Satisfaction of Indenture. 
 NOW THEREFORE, THIS SATISFACTION AND DISCHARGE
WITNESSETH: 
  

	 	1.	The Indenture is discharged and ceases to be of further effect; provided, however, that notwithstanding the satisfaction and discharge of the Indenture, (a) the
provisions of Sections 10.02 (“Application of Trust Money”) and 8.06 (“Repayment to Company”) of the Indenture shall survive and (b) unless otherwise set forth herein, this Satisfaction of Indenture shall not be deemed to
discharge those provisions of Section 7.07 (“Compensation and Indemnity”) of the Indenture that, by their terms, survive the satisfaction and discharge of the Indenture. 

	 	2.	All Liens and Mortgages on the Collateral and all other property of the Company or any Guarantor, and all related rights in respect thereof, securing Obligations under
the Indenture, the Notes or the Note Guarantees (whether created by the Indenture, any Collateral Agreement, the Intercreditor Agreement or any other Indenture Document), including the Liens granted pursuant to Section 7.07(d) of the Indenture,
are hereby released, discharged and terminated. 

  

	 	3.	All obligations of the Company and the Guarantors under the Indenture and the Note Guarantees are deemed fully satisfied, discharged, terminated, released and null and
void. 

  

	 	4.	The Trustee agrees to take all actions and to execute all documents which the Company reasonably deems necessary or appropriate to give effect to the foregoing.

 This Satisfaction of Indenture shall be governed by, and construed in accordance with, the laws of the State of New York.
