the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream will be applicable to transfers of beneficial interests in the Regulation S Global Note that are held by Participants through
Euroclear or Clearstream. 
 Section 2.02 Execution and Authentication. 

At least one Authorized Officer must sign the Notes for the Issuer by manual or facsimile signature. 

If an Authorized Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will
nevertheless be valid. 
 A Note will not be valid until authenticated by the manual signature of the Trustee. The signature
will be conclusive evidence that the Note has been authenticated under this Indenture. 
 The Trustee will, upon receipt of a
written order of the Issuer signed by an Authorized Officer (an “Authentication Order”), authenticate Notes for original issue that may be validly issued under this Indenture, up to the aggregate principal amount of
$700,000,000. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Issuer pursuant to one or more Authentication Orders, except as provided in
Section 2.07 hereof. 
 The Trustee may appoint an authenticating agent acceptable to the Issuer to authenticate Notes. An
authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with
Holders or an Affiliate of the Issuer. 
 Section 2.03 Registrar and Paying Agent. 

The Issuer will maintain an office or agency where Notes may be presented for registration of transfer or for exchange
(“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuer may
appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent, including the Luxembourg Paying Agent.
The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuer fails to appoint or maintain another
entity as Registrar or 

  
 26 









 
Paying Agent, the Trustee shall act as such. The Issuer may act as Paying Agent or Registrar. So long as the Notes are listed on the Official List of the Luxembourg Stock Exchange and the rules
of the Official List of the Luxembourg Stock Exchange so require, the Issuer shall appoint and maintain an office or agency in Luxembourg where the Notes may be presented or surrendered for payment or redemption, in the event that the Global Notes
are exchanged for Definitive Notes (the “Luxembourg Paying Agent”). 
 The Issuer initially
appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes. 
 The
Issuer initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes. The Issuer initially appoints Deutsche Bank Luxembourg S.A. to act as the Luxembourg Paying Agent. 

Section 2.04 Paying Agent to Hold Money in Trust. 
 The Issuer will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent
for the payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee of any default by the Issuer in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer) will have no further liability for the money. If
the Issuer acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Issuer, the Trustee will
serve as Paying Agent for the Notes. 
 Section 2.05 Holder Lists. 

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and
addresses of all Holders and shall otherwise comply with TIA §312(a). If the Trustee is not the Registrar, the Issuer will furnish to the Trustee at least seven Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes. 
 Section 2.06 Transfer and Exchange. 
 (a) Transfer and
Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or
any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Issuer for Definitive Notes if: 
 (i) the Issuer delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange
Act and, in either case, a successor Depositary is not appointed by the Issuer within 120 days after the date of such notice from the Depositary; 
 (ii) the Issuer in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee;
provided that in no event shall the Regulation S Global Note be exchanged by the Issuer for Definitive Notes prior to the expiration of the Restricted Period; or 

  
 27 









 (iii) there has occurred and is continuing a Default with respect to the
Notes and any Holder of the Notes requests that Definitive Notes be issued. 
 Upon the occurrence of any of the preceding
events in clauses (i), (ii) or (iii) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and
2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Sections 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and
shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b),
(c) or (d) hereof. 
 (b) Transfer and Exchange of Beneficial Interests in the Global Notes. The

Registrar to effect the transfers described in this Section 2.06(b)(i).

(i) To permit registrations of transfers and exchanges, the Issuer will execute and the Trustee will authenticate Global
Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 
 (ii) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note for any registration of transfer or exchange, but the Issuer may require
payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10,
3.06, 4.10(c), 4.15, 4.19 and 9.04 hereof). 
 (iii) The Registrar will not be required to register the transfer
of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 (iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Issuer, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange. 
 (v) Neither the Registrar nor the Issuer will be required: 
 (A)
to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on
the day of selection; 

  
 37 









 (B) to register the transfer of or to exchange any Note selected for
redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or 
 (C) to
register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date. 
 (vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner
of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and none of the Trustee, any Agent or the Issuer shall be affected by notice to the contrary. 

(vii) The Trustee will authenticate Global Notes and Definitive Notes in accordance with the provisions of
Section 2.02 hereof. 
 (viii) All certifications, certificates and Opinions of Counsel required to be
submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile. 

Section 2.07 Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuer will issue and the
Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the
judgment of (i) the Trustee to protect the Trustee and (ii) the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent, from any loss that any of them may suffer if a Note is replaced. The Issuer may charge for
its expenses in replacing a Note. 
 Every replacement Note is an additional obligation of the Issuer and will be entitled to
all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder. 
 Section 2.08 Outstanding
Notes. 
 The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled by it,
those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in
Section 2.09 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Issuer or an Affiliate of the Issuer shall not be deemed to be outstanding for purposes of
Section 3.07(a) hereof. 
 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless
the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 

  
 38 









 If the principal amount of any Note is considered paid under Section 4.01 hereof, it
ceases to be outstanding and interest on it ceases to accrue. 
 If the Paying Agent (other than the Issuer or an Affiliate of
any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest. 

Section 2.09 Treasury Notes. 
 In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or a Guarantor, or by any of their respective
Affiliates, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee
knows are so owned will be so disregarded. 
 Section 2.10 Temporary Notes. 

Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication
Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee.
Without unreasonable delay, the Issuer will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes. 
 Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 

Section 2.11 Cancellation. 

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy cancelled Notes
(subject to the record retention requirement of the Exchange Act or the Trustee). Certification of the destruction or cancellation of all cancelled Notes will be delivered to the Issuer upon written request. The Issuer may not issue new Notes to
replace Notes that it has paid or that have been delivered to the Trustee for cancellation. 
 Section 2.12 Defaulted Interest. 

If the Issuer defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuer will notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer will fix or cause to be fixed each such special record date and payment date; provided that no such special record date may be
less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) will
mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

 ARTICLE 3 
 REDEMPTION AND PREPAYMENT 
 Section 3.01 Notices to Trustee. 

If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, it must furnish to the
Trustee, at least 30 days but not more than 60 days before a redemption date, an Officers’ Certificate setting forth: 
 (i) the clause of this Indenture pursuant to which the redemption shall occur; 
 (ii) the redemption date; 
 (iii) the principal amount of Notes to
be redeemed; and 
 (iv) the redemption price. 
 Section 3.02 Selection of Notes to Be Redeemed or Purchased. 
 If less than
all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee will select Notes for redemption or purchase on a pro rata basis (or, in the case of Global Notes, based on a method that most nearly
approximates a pro rata selection in accordance with the procedures of the Depositary), unless otherwise required by applicable Law or applicable stock exchange requirements. 

In the event of partial redemption, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein,
not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase. 
 The Trustee will promptly notify the Issuer in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount
thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $200,000 and whole multiples of $1,000 in excess thereof; provided that if all of the Notes of a Holder are to be redeemed or purchased, the
entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. No Notes will be redeemed in part if such partial redemption results in Notes with less than $200,000. Except as provided in
the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase. 
 Section 3.03 Notice of Redemption or Offer to Purchase. 
 At least 30 days
but not more than 60 days before a redemption date, the Issuer will mail or cause to be mailed, by first class mail, postage prepaid, a notice of redemption to the Trustee on behalf of each Holder whose Notes are to be redeemed at its registered
address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12
hereof. 
 The notice will identify the Notes to be redeemed and will state: 

(i) the redemption date; 

  
 40 









 (ii) the redemption price; 

(iii) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that,
after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note; 

(iv) the name and address of the Paying Agent; 

(v) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

(vi) that, unless the Issuer defaults in making such redemption payment, interest on Notes called for redemption ceases to
accrue on and after the redemption date; 
 (vii) the paragraph of the Notes and/or Section of this Indenture
pursuant to which the Notes called for redemption are being redeemed; and 
 (viii) that no representation is
made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes. 
 At the
Issuer’s request, the Trustee will give the notice of redemption in the Issuer’s name and at its expense; provided, however, that the Issuer has delivered to the Trustee, at least 10 days prior to the date the notice needs to be
sent, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. 

At least 30 days but not more than 60 days before an Offer Expiration Date, the Issuer will mail or cause to be mailed, by first class
mail, postage prepaid, a notice of any Offer to Purchase to the Trustee on behalf of each Holder at its registered address, which notice shall specify (i) the principal amount of Notes subject to the Offer to Purchase, (ii) the purchase
price of the offer, (iii) an expiration date (the “Offer Expiration Date”) not less than 30 days nor more than 60 days after the date of the Offer to Purchase and (iv) a settlement date for purchase (the “Offer
Purchase Date”) not more than five Business Days after the Offer Expiration Date. Such written notice shall additionally include (i) information concerning the business of the Issuer and the Guarantors which the Issuer and the
Guarantors in good faith believe will enable the Holders to make an informed decision with respect to the Offer to Purchase and (ii) instructions and materials necessary to enable Holders to tender their respective Notes pursuant to the Offer
to Purchase. 
 Section 3.04 Effect of Notice of Redemption. 
 Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of
redemption may not be conditional. 
 Section 3.05 Deposit of Redemption or Purchase Price. 

One Business Day prior to the redemption or purchase date, the Issuer will deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption or purchase price of all Notes to be redeemed or purchased on that date together with accrued and unpaid interest and Additional Amounts, 

  
 41 









 
if any, thereon, to, but excluding, the applicable redemption or purchase date. The Trustee or the Paying Agent will promptly return to the Issuer any money deposited with the Trustee or the
Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption or purchase price of all Notes to be redeemed or purchased on that date together with accrued and unpaid interest and Additional Amounts, if any, thereon, to, but
excluding, the applicable redemption or purchase date. 
 In connection with any redemption or Offer to Purchase, the applicable
Guarantor shall make a prepayment on its Intercompany Note to the extent necessary to allow the Issuer to consummate such redemption or Offer to Purchase, as the case may be, and the Issuer shall thereupon consummate such redemption or Offer to
Purchase, as the case may be, in accordance with the terms of this Indenture. 
 If the Issuer complies with the provisions of
the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after an interest record date but
on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is
not so paid upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and
to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 
 Section 3.06 Notes Redeemed or Purchased in Part. 
 Upon surrender of a Note
that is redeemed or purchased in part, the Issuer will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed or
unpurchased portion of the Note surrendered. 
 Section 3.07 Optional Redemption. 

(a) At any time prior to November 30, 2016, the Issuer may on any one or more occasions redeem the Notes, at its
option, in whole or in part, at a “make-whole” redemption price equal to the greater of (i) 101% of the principal amount of the Notes being redeemed and (ii) the present value at such redemption date of all required interest and
principal payments on such Notes through the final maturity date (excluding accrued but unpaid interest to the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at
the Treasury Rate plus 50 basis points; plus in each case any accrued and unpaid interest and Additional Amounts, if any, on such Notes to, but excluding, the redemption date, as calculated by the Independent Investment Banker. 

Any redemption of Notes by the Issuer pursuant to this paragraph will be subject to either (i) there being at least U.S.$150.0
million in aggregate principal amount of Notes outstanding after such redemption or (ii) the Issuer redeeming all of the then-outstanding principal amount of the Notes. 

(b) On any Semi-Annual Payment Date occurring in November 2016 or at any time thereafter until (but not including) the
Semi-Annual Payment Date occurring in November 2017, the Issuer may redeem all, but not less than all, of the Notes, at a redemption price equal to 101% of the then outstanding principal amount of the Notes, plus accrued and unpaid interest and
Additional Amounts, if any, to, but excluding, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date). 

  
 42 









 (c) On any Semi-Annual Payment Date occurring in November 2017 or at any
time thereafter, the Issuer may redeem all, but not less than all, of the Notes, at 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the redemption date
(subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).\ 
 (d) If as a result of any change in or amendment to the applicable Laws of a Relevant Jurisdiction, or any amendment to or change in an official interpretation, administration or application of such Laws
(including a holding, judgment or order by a court of competent jurisdiction), which change or amendment or change in official position becomes effective on or after the Issue Date or on or, with respect to a successor, after the date a successor
assumes the obligations under the Notes, the Issuer, the Guarantors or any successor have or will become obligated to pay Additional Amounts, the Issuer may, at its option, redeem all, but not less than all, of the Notes, at a redemption price equal
to 100% of the principal amount of the Notes to be redeemed, together with accrued and unpaid interest, if any, to, but excluding, the applicable redemption date, upon publication of irrevocable notice not less than 30 days nor more than 60 days
prior to the applicable redemption date; provided that no notice of such redemption may be given earlier than 60 days prior to the earliest date on which the Issuer, the Guarantors or any successor would, but for such redemption, be obligated
to pay the Additional Amounts. Notwithstanding the foregoing, the Issuer shall not have the right to so redeem the Notes unless: (i) it has used commercially reasonable efforts to avoid the obligation to pay Additional Amounts; and (ii) it
has complied with all applicable Laws to legally effect such redemption; provided, however, that for this purpose commercially reasonable efforts shall not include, without limitation, any change in the Issuer’s or any successor’s,
corporate form, jurisdiction of incorporation or organization or location of its principal executive or registered office. In the event that the Issuer elects to so redeem the Notes, it will deliver to the Trustee: (1) a certificate of an
Authorized Officer of the Issuer stating that the Issuer is entitled to redeem the Notes pursuant to the indenture and setting forth a statement of facts showing that the condition or conditions precedent to the right of the Issuer to so redeem have
occurred or been satisfied; and (2) an opinion of counsel to the effect that the Issuer has or will become obligated to pay Additional Amounts and that all governmental approvals necessary for the Issuer to effect the redemption have been
obtained and are in full force and effect. 
 (e) Any redemption pursuant to this Section 3.07 shall be made
in accordance with the provisions of Sections 3.01 through 3.06 hereof. 
 Section 3.08 Mandatory Redemption. 

If, as of the Note Proceeds Account Release Date, (i) the Existing Project Finance Obligations are not repaid or purchased by the Issuer in full or
(ii) all funds on deposit in the Note Proceeds Account are not released, then the Issuer shall instruct the Collateral Agent to disburse all funds then held on deposit in the Note Proceeds Account to the Trustee and redeem the maximum principal
amount of Notes, together with accrued and unpaid interest, if any, thereon to, but excluding, the applicable redemption date (subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment
date) that may be redeemed with the funds then held on deposit in the Note Proceeds Account, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, together with accrued and unpaid interest, if any, thereon to, but
excluding, the applicable redemption date. 
 Section 3.09 Offers to Purchase. 

(a) A Holder may tender all or any portion of its Notes pursuant to an Offer to Purchase; provided that, to the
extent any Holder tenders less than all of its Notes, any Note that is not tendered must be for a minimum denomination of $200,000; provided, further, that any portion of a Note tendered pursuant to an Offer to Purchase must be in a
multiple of $1,000 principal amount. 

  
 43 









 (b) On the Offer Purchase Date, the purchase price specified in the written
offer will become due and payable on each Note accepted for purchase pursuant to the Offer to Purchase, and interest on Notes purchased pursuant to such Offer to Purchase will cease to accrue on and after the Offer Purchase Date. 

(c) If (i) the Issuer makes an Offer to Purchase for less than all of the outstanding Notes and (ii) Notes in an
aggregate principal amount in excess of the purchase amount specified in the written offer are tendered and not withdrawn pursuant to the Offer to Purchase, then the Issuer will purchase Notes having an aggregate principal amount equal to the
purchase amount specified on the written offer on a pro rata basis; provided that adjustments shall be made so that only Notes in multiples of $1,000 principal amount will be purchased. 

(d) Any Offer to Purchase shall be made by the Issuer in compliance with Rule 14e-1 under the Exchange Act (to the extent
applicable) and all other applicable Laws, and the procedures set forth in this Indenture shall be deemed to be modified as necessary to permit such compliance. The Issuer and Guarantors shall additionally obtain all necessary consents and approvals
from any Governmental Authority for any required remittance of funds outside of any jurisdiction in connection with any Offer to Purchase. 
 (e) Notwithstanding anything herein to the contrary, the Issuer shall not be required to make an Offer to Purchase pursuant to the terms of this Indenture if (i) a third party makes an offer to
purchase Notes in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to an Offer to Purchase made by the Issuer and such third party purchases all Notes properly tendered and not
withdrawn by the Holders thereof under such offer to purchase or (ii) if notice of redemption for all outstanding Notes has been given pursuant to Section 3.07 or 3.08 hereof, unless and until there is a default in payment of the
applicable redemption price. 
 ARTICLE 4

 Each of the Issuer and the Guarantors shall duly pay and discharge before they become overdue all material taxes, assessments and other governmental charges or levies imposed by a Governmental Authority
upon it or its Property, income or profits; provided that any of the Issuer or the Guarantors may contest in good faith any such tax, assessment, charge, levy, claim or obligation and, in such event, may permit the tax, assessment, charge,
levy, claim or obligation to remain unpaid during any period, including appeals, when the Issuer or such Guarantor is in good faith contesting the same by proper proceedings, so long as (i) adequate reserves shall have been established with
respect to any such tax, assessment, charge, levy, claim or obligation, accrued interest thereon and potential penalties or other costs relating thereto, or other adequate provision for payment thereof shall have been made, and (ii) such
contest would not reasonably be expected to result in a Material Adverse Effect.

compliance with, all requirements of applicable Law, including all Necessary Governmental Approvals, Environmental Laws, the International Safety Management (ISM) Code and the International Ship and Port Facility Security (ISPS) Code, except where
any failure to comply would not individually or in the aggregate reasonably be expected to result in a Material Adverse Effect; provided that any of the Issuer or the Guarantors may, at its expense, contest by appropriate proceedings
conducted in good faith the validity or application of any such requirement of applicable 

  
 46 









 
Law, so long as (a) none of the Secured Parties would be subject to any liability for failure to comply therewith and (b) the institution of such proceedings would not reasonably be
expected to result in a Material Adverse Effect. 
 Section 4.06 Stay, Extension and Usury Laws. 

Each of the Issuer and the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon,
plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and each of
the Issuer and the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted. 

Section 4.07 Restricted Payments. 
 Neither the Issuer nor either Guarantor will, directly or indirectly: 
 (i) declare or pay any dividend or make any other payment or distribution on account of the Issuer or such Guarantor’s Equity Interests (including, without limitation, any payment in connection with
any merger or consolidation involving the Issuer or such Guarantor) or to the direct or indirect holders of the Issuer’s or such Guarantor’s Equity Interests in their capacity as such, other than, in each case, (i) dividends or

 Section 4.08 Additional Amounts.

 (a) All payments made by the Issuer with respect to the Notes or by the Guarantors with respect to the Note
Guarantees will be made free and clear of and without withholding or deduction for or on account of any present or future taxes, duties, assessments, or other governmental charges of whatever nature (collectively, “Taxes”) imposed
or levied by or on behalf of the Cayman Islands, Brazil, the British Virgin Islands or any other jurisdiction in which the Issuer or either Guarantor is resident for tax purposes, or any other jurisdiction through which any such payments under the
Notes or the Note Guarantees are made, or any political subdivision of any such jurisdiction having power to tax (each, a “Relevant Jurisdiction”) unless the Issuer or the Guarantors are compelled by applicable Law to deduct or
withhold such taxes, duties, assessments, or governmental charges. 

  
 48 









 (b) If the Issuer or the Guarantors are so required to deduct or withhold or
deduct any amounts for or on account of Taxes from any payment made under or with respect to the Notes or the Note Guarantees, as applicable, the Issuer or the Guarantors, as applicable, will make such deduction or withholding, make payment of the
amount so withheld to the appropriate Governmental Authority and pay such additional amounts (“Additional Amounts”) as may be necessary such that the net amounts received in respect of such payment by such Holder (including
Additional Amounts) after such withholding or deduction shall equal the respective amounts of principal, interest or other amounts which such Holder would have received in respect of the Notes or under the Note Guarantees if such Taxes had not been
required to be so withheld or deducted; provided that no Additional Amounts will be payable with respect to a payment made to a Holder: 
 (i) to, or to a third party on behalf of, a Holder who is liable for such taxes, duties, assessments or governmental charges in respect of such Note or Note Guarantee by reason of the existence of any
present or former connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of such Holder, if such Holder is an estate, a trust, a partnership, a limited liability company or a corporation) and the Relevant
Jurisdiction, including, without limitation, such Holder (or such fiduciary, settlor, beneficiary, member or shareholder) being or having been a citizen or resident thereof or being or having been engaged in a trade or business or present therein or
having, or having had, a permanent establishment therein, other than the mere holding of the Note or the benefit of the Note Guarantees or enforcement of rights and the receipt of payments with respect to the Note or the Note Guarantees; 

(ii) in respect of any Note presented for payment more than 30 days after the Relevant Date, except to the extent that the
Holder of such Note would have been entitled to such Additional Amounts on surrender of such Note for payment on or prior to the last day of such period of 30 days; 

(iii) where such Additional Amount is imposed on a payment to an individual and is required to be made pursuant to any
applicable Law implementing or complying with, or introduced in order to conform to, European Council Directive 2003/48/EC or any other directive implementing the conclusions of the ECOFIN Council Meeting of 26-27 November 2000; 

(iv) to, or to a third party on behalf of, a Holder who is liable for such taxes, duties, assessments or other
governmental charges by reason of such Holder’s failure to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with the Relevant Jurisdiction, if
(1) compliance is required by the Relevant Jurisdiction, as a precondition to, exemption from, or reduction in the rate of, the tax, assessment or other governmental charge and (2) the Issuer has given the Holders at least 30 days’
notice that Holders will be required to provide such certification, identification or other requirement; 
 (v)
in respect of any estate, inheritance, gift, sales, transfer, capital gains, excise or personal property or similar tax, assessment or governmental charge; 
 (vi) in respect of any tax, assessment or other governmental charge which is payable other than by deduction or withholding from payments of principal of or interest on the Note or payments by the
Guarantors under the Note Guarantees or is otherwise payable by direct payment by the Issuer or the Guarantors in respect of claims made against the Issuer or the Guarantors under the Financing Documents; 

  
 49 









 (vii) any tax, assessment or other governmental charge required to be
withheld by any paying agent from any payment of principal, premium (if any) or interest on the Notes or any payment by the Guarantors if such tax, assessment or other governmental charge results from the presentation of such Note for payment (in
cases in which presentation is required) and the payment can be made without such withholding or deduction by the presentation of such Note for payment to another available paying agent of the Issuer; or 

(viii) in respect of any combination of the above. 

(c) Notwithstanding anything herein to the contrary, no Additional Amounts shall be paid with respect to any payment on a
Note to a Holder who is a fiduciary, a partnership, a limited liability company or other than the sole beneficial owner of that payment to the extent that payment would be required by the applicable Laws of the Relevant Jurisdiction to be included
in the income, for tax purposes, of a beneficiary or settlor with respect to the fiduciary, a member of that partnership, an interest holder in a limited liability company or a beneficial owner who would not have been entitled to the Additional
Amounts had that beneficiary, settlor, member or beneficial owner been the Holder of such Note. 
 (d) In the
event that Additional Amounts actually paid with respect to the Notes or under the Note Guarantees described above are based on rates of deduction or withholding of withholding taxes in excess of the appropriate rate applicable to the Holder of such
Notes or the benefit of the Note Guarantees, and, as a result thereof such Holder is entitled to make claim for a refund or credit of such excess from the Governmental Authority imposing such withholding tax, then such Holder shall, by accepting
such Notes and the benefit of such Note Guarantees, be deemed to have assigned and transferred all right, title, and interest to any such claim for a refund or credit of such excess to the Issuer or the Guarantors, as applicable. 

(e) Whenever in this Indenture or the Notes there is mentioned, in any context, the payment of principal (and premium, if
any), interest or any other amount payable under or with respect to any Note, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in this Section 4.08 to the extent that, in such context, Additional
Amounts are, were or would be payable in respect thereof. 
 (f) The obligations to make payments of Additional
Amounts with respect to principal, interest or other amounts payable on the Notes or the Note Guarantees will survive any termination or discharge of this Indenture, payment of the Notes, discharge of the Note Guarantees and/or the resignation or
removal of the Trustee, the Collateral Agent or any Agent hereunder.

reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of Disqualified Stock will not be deemed to be an
incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of this Section 4.09. 
 Section 4.10 Dispositions.

 (a) Neither Guarantor shall consummate a Disposition unless (1) such Disposition is for Fair Market Value
and otherwise permitted under this Indenture, and (2) at least 90% of the consideration therefor received by the applicable Guarantor is in the form of cash, Cash Equivalents or Replacement Assets or any combination thereof. For the purposes of
this Section 4.10(a), the assumption by the purchaser of Indebtedness or other obligations (other than Permitted Subordinated Indebtedness) of the applicable Guarantor pursuant to customary arrangements, and instruments or securities received
from the purchaser that are promptly, but in any event within 30 days of the closing, converted by the applicable Guarantor to cash, to the extent of the cash actually so received, shall be considered cash received at closing. 

(b) Within 360 days after the receipt by a Guarantor of any Net Disposition Proceeds, such Guarantor may apply up to an amount in
aggregate equal to such Net Disposition Proceeds to make any capital expenditure or to purchase Replacement Assets (or enter into a binding agreement to make such capital expenditure or to purchase any such Replacement Assets); provided that
such capital expenditure or purchase is consummated within the later of (x) 360 days after the receipt of the relevant Net Disposition Proceeds and (y) 180 days after the date of such binding agreement. 

(c) Subject to Section 3.09(e), when accumulated Excess Disposition Proceeds equal or exceed $25.0 million, the Issuer shall, within
30 days, make an Offer to Purchase the maximum principal amount of Notes, together with accrued and unpaid interest, if any, thereon to, but excluding, the applicable purchase date (subject to the rights Holders on the relevant record date to
receive interest due on the relevant interest payment date) that may be purchased with the Excess Disposition Proceeds (any such offer, an “Excess Disposition Offer”), at a purchase price equal to 100% of the principal amount of the
Notes to be purchased, together with accrued and unpaid interest, if any, thereon to, but excluding, the applicable purchase date. For the avoidance of doubt, upon the completion of any Excess Disposition Offer, Excess Disposition Proceeds will be
reset at zero, and any Excess Disposition Proceeds remaining after giving effect to the consummation of such Excess Disposition Offer may be used for any purpose not otherwise prohibited in this Indenture.

 (i) the Affiliate Transaction is on terms that are no less favorable to such
Guarantor than those that would have been obtained in a comparable arm’s-length transaction with a Person that is not an Affiliate of such Guarantor; and 

  
 51 









 (ii) prior to an Affiliate Transaction for any transaction amount in excess
of $15.0 million, the applicable Guarantor delivers to the Trustee a certificate of an Authorized Officer of such Guarantor stating that such Affiliate Transaction complies with the Indenture; 

provided, that the restrictions and conditions set forth in this Section 4.11 shall not apply to any Affiliate Transaction (i) under any
Project Document that is effective as of the Issue Date, (ii) under any Financing Document, (iii) entered into in order to consummate the Hopelake Acquisition, (iv) entered into in order to consummate the Issuer Reorganization,
(v) entered into in order to consummate the Asset reorganization; (vi) between the Issuer and the Guarantors, (vii) between the Guarantors (including, for the avoidance of doubt, the Bareboat Charter Agreement), (viii) consisting
of Constellation Intercompany Debt (or the repayment thereof), or (ix) consisting of Second Note Proceeds Intercompany Debt. 

Section 4.12 Liens. 

Neither Guarantor will directly or indirectly, create, incur, assume or suffer to exist any Lien of any kind on any Property now owned or
hereafter acquired, except Permitted Liens. 
 Section 4.13 Limitation on Leases and Sale and Leaseback Transactions. 

Neither Guarantor shall enter into any agreement, or be or become liable as lessee under any agreement, for the lease, hire or use of any
Property, except for operating leases of Property (which do not constitute Capital Lease Obligations); provided that such Guarantor’s aggregate payment obligations under all such operating leases shall not exceed $5.0 million in any
calendar year. Neither Guarantor shall enter into any Sale and Leaseback Transaction.

	 	(ii)	comply, in all material respects, with its Organizational Documents; 

  

	 	(iii)	in the case of the Guarantors, engage solely in the business of owning, operating and maintaining the Facilities and activities ancillary thereto and any other activity

	 	(iv)	 refrain from making any amendments to its Organizational Documents other than those that would not reasonably be expected to (i) result in a
Material Adverse Effect or (ii) increase the risk of the Issuer or such Guarantor of being 



  
 52 










	 	
consolidated with another Person in the event of a bankruptcy of the Issuer or such Guarantor, including, for the avoidance of doubt, amendments necessary in connection with a merger or
consolidation of any of the Issuer or the Guarantors permitted under Article 5 hereof. 

 Section 4.15 Offer to Repurchase
Upon Change of Control. 
 Subject to Section 3.09(e), not later than 30 days following a Change of Control that results in
a Rating Decline, the Issuer shall make an Offer to Purchase all, but not less than all, of the Notes at a purchase price equal to 101% of the outstanding principal amount of the Notes to be purchased, together with accrued and unpaid interest, if
any, thereon to, but excluding, the applicable purchase date (subject to the rights of the Holders on the relevant record date to receive interest due on the relevant interest payment date) (any such offer, a “Change of Control
Offer”). Such Change of Control Offer may be made in advance of a Change of Control and conditioned upon the consummation of such Change of Control; provided that a definitive agreement is in place for such Change of Control at the
time such Offer to Purchase is made. The Issuer shall mail or cause to be mailed notice of a Change of Control Offer in accordance with Section 3.03 hereof.

inspect its Properties, and to discuss its business and affairs with its (and the Operating Company’s) officers and engineers, all to the extent reasonably requested by the Trustee, the Insurance Advisor or the Independent Engineer, provided,
however, that such visits and inspections shall be subject to availability of transportation and, if required, approval by Petrobras. Each Guarantor will assist the officers and designated representatives of the Trustee, the Insurance Advisor and
the Independent Engineer in its communications with such Guarantor’s independent auditors (whose fees and expenses shall be for the account of such Guarantor) regarding such Guarantor’s accounts and operations; provided, however, that upon
the occurrence of a Default or an Event of Default and its continuance, the officers and designated representatives of the Trustee, the Insurance Advisor and the Independent Engineer shall be entitled to communicate directly with each
Guarantor’s independent auditors (whose fees and expenses shall be for the account of such Guarantor), it being understood that representatives of the applicable Guarantor will participate in any such direct communication, at any reasonable
time and upon prior written notice to the Guarantor, regarding such Guarantor’s accounts and operations. 

(b) Each Guarantor shall permit, and cause the Operating Company to permit, the Trustee, the Independent Engineer and the
Insurance Advisor to review (i) any quality control data and (ii) any other data relating to the Project as may be reasonably requested by the Trustee, the Independent Engineer or the Insurance Advisor, as the case may be. 

(c) For the avoidance of doubt, so long as no Event of Default shall have occurred and be continuing, (i) inspections

 53

contested by appropriate proceedings in accordance with this Indenture, and (b) the failure to obtain or maintain such Necessary Governmental Approval or any such proceedings would not reasonably be expected to result in a Material Adverse
Effect. 
 Section 4.18 Insurance. 
 To the extent available to each Guarantor on commercially reasonable terms, and to the extent permitted by applicable Law, such Guarantor shall maintain or cause to be maintained in full force and effect,
with financially sound insurers of international standing, insurance coverage for the Project in relation to its operations and Property in accordance with Good Practices, including: 

(a) hull and machinery insurance and increased value insurance, with a combined policy limit equal to 100% of the
aggregate outstanding principal under the Notes; 
 (b) war risks insurance, with a combined policy limit equal
to the aggregate outstanding principal under the Notes; and 
 (c) protection and indemnity insurance, with a
policy limit equal to $150.0 million in respect of each Drilling Rig. 
 Such insurance shall (i) name such Guarantor as
named insured and loss payee, and (ii) note the interest of the Collateral Agent thereon as a mortgagee and loss payee (other than under third-party liability insurance policies) for its rights and interests. The Guarantors shall cause all
Insurance Proceeds to be applied in accordance with the terms of this Indenture.

Events of Loss. 
 (a) If an Event of Loss shall occur, each Guarantor may apply any Net Available Amount
received by it as a result of such Event of Loss to Restore (or reimburse the Sponsor for the costs of Restoration of) the Affected Property without any obligation of the Issuer to make a purchase of Notes pursuant to this Indenture; provided
that if in respect of such Event of Loss (x) the Affected Property constitutes the entirety or any portion of either Drilling Rig (“Affected Drilling Rig Property”) and (y) the Net Available Amount in respect of such
Event of Loss is equal to or greater than $35.0 million, then the applicable Guarantor may not apply such Net Available Amount to Restore (or reimburse the Sponsor for the costs of Restoration of) the Affected Drilling Rig Property unless, for any
such Event of Loss, the applicable Guarantor delivers to the Collateral Agent and Trustee within 120 days of the occurrence of such Event of Loss a certificate of an Authorized Officer of the applicable Guarantor and a written verification from the
Independent Engineer, each stating that the aggregate of all Net Available Amounts, funds on deposit in the Guarantor Collateral Accounts, binding equity commitments with respect to funds, anticipated Insurance Proceeds and any available proceeds
from Permitted Subordinated Indebtedness or a Permitted Equity Issuance are sufficient to (x) Restore the Affected Drilling Rig Property or reimburse the Sponsor for the costs of Restoration thereof, as the case may be, and (y) pay
scheduled principal and interest on the Notes during the period of such Restoration. 

  
 54 









 (b) Subject to Section 3.09(e), when accumulated Excess Loss Proceeds
equal or exceed $35.0 million, the Issuer shall, within 30 days, make an Offer to Purchase the maximum principal amount of Notes, together with accrued and unpaid interest, if any, thereon to, but excluding, the applicable purchase date (subject to
the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date) that may be purchased with the Excess Loss Proceeds (any such Offer to Purchase, an “Excess Loss Offer”), at a purchase
price equal to 100% of the principal amount of the Notes to be purchased, together with accrued and unpaid interest, if any, thereon to, but excluding, the applicable purchase date. For the avoidance of doubt, upon completion of any Excess Loss

its Drilling Rig will have the capacity and functional ability to perform, on a continuing basis (ordinary wear and tear excepted), in normal commercial operation, in each case, pursuant to the Charter Agreement and the Services Agreement to which
such Guarantor is a party, unless such failure to so maintain and preserve such Drilling Rig and other Properties would not reasonably be expected to result in a Material Adverse Effect.

material part of its Drilling Rig, except if any such alteration, remodeling, addition, removal, reconstruction, improvement or demolition (i) would not reasonably be expected to result in a Material Adverse Effect and (ii) such Guarantor
obtains written verification by the Independent Engineer that such alteration, remodeling, addition, removal, reconstruction, improvement or demolition would not reasonably be expected to result in a material adverse effect on the performance of
such Guarantor’s or the Operating Company’s obligations under any Charter Agreement and the Services Agreement to which such Guarantor is a party, provided that such verification need not be obtained if such alteration, remodeling,
addition, removal, reconstruction, improvement or demolition arises solely in connection with an Event of Loss or Disposition permitted under this Indenture or as a result of a request from Petrobras in accordance with the terms of the relevant
Charter Agreement. 
 (d) Neither Guarantor shall, directly or indirectly, make or commit to make any expenditure
in respect of the purchase or other acquisition of fixed or capital Property, other than (i) expenditures reasonably required in connection with the Project, (ii) expenditures of any Net Available

terms), unless (i) such Guarantor obtains a Ratings Affirmation in connection with such failure to perform and observe or such termination or (ii) such Guarantor shall deliver to the Trustee (A) a certificate of an Authorized Officer
of such Guarantor describing in reasonable detail such failure to perform and observe or such termination and stating that such failure to perform and observe or such termination would not reasonably be expected to result in a Material Adverse

the relevant Project Document, written verification by the Independent Engineer that such failure to perform and observe would not reasonably be expected to result in a material adverse effect on the viability of the Project.

rescinded or annulled within five Business Days; 
 (iv) failure by the Issuer or the Guarantors to comply with

of the Sponsor or (2) 90 days in respect of a Operating Company that is not an Affiliate of the Sponsor, of the occurrence of such event;

and the same shall not be discharged (or provision shall not be made for 

  
 63 









 
such discharge), or a stay of execution thereof shall not be procured, within 60 days from the date of entry thereof and the Issuer or either Guarantor, as the case may be, shall not, within such
60-day period, or such longer period during which execution of the same shall have been stayed, appeal therefrom and cause the execution thereof to be stayed during such appeal 

(viii) any of the Secured Parties shall cease to have a first priority, perfected Lien on any Collateral to the extent

 (x) either Guarantor shall have

 (xi) an Expropriation Event shall have occurred; provided that, with

Expropriation Event (or lesser period if such Guarantor shall not at all times during such period of 60 days be acting diligently to contest, discharge, settle or secure the same); provided that such 60-day period shall be extended for an

 (xii) the Note Guarantee of either Guarantor ceases to be in full force and effect, other than in accordance with the terms of this Indenture, or either Guarantor denies or disaffirms in writing its
obligations under its Note Guarantee. 
 For the avoidance of doubt, a failure to make a funding of Guarantor Collateral
Accounts in accordance with the Guarantor Accounts Agreement (other than the failure to timely make such initial funding of the Offshore O&M Service Reserve Account and the Offshore Debt Service Reserve Account) shall not by itself be an Event
of Default hereunder if it is the result of insufficient funds being available for such funding in such Guarantor Collateral Accounts. 

Section 6.02 Acceleration. 

If an Event of Default, other than an Event of Default specified in clause (v) or (vi) of Section 6.01 hereof, occurs and
is continuing under this Indenture, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, by written notice to the Issuer (and to the Trustee if the notice is given by the Holders of the Notes) may,
and the Trustee at the written request of such Holders shall, declare all the Notes to be due and payable immediately, including all unpaid principal and accrued and unpaid interest, if any, thereon. 

  
 64 









 Upon any such declaration, the Notes shall become automatically due and payable
immediately. Upon an Event of Default specified in clause (v) or (vi) of Section 6.01 hereof, all Notes then outstanding will become due and payable immediately, including all unpaid principal and accrued and unpaid interest, if any,
thereon, without further action or notice on the part of the Trustee or any Holder. 
 The Majority Holders by written notice to
the Issuer and to the Trustee may, on behalf of all of the Holders, rescind and annul a declaration of acceleration and its consequences if: 
 (i) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by the declaration of acceleration, have been
cured or waived; and 
 (ii) the rescission would not conflict with any judgment or decree of a court of
competent jurisdiction. 
 No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

Section 6.03 Notice of Event of Default; Other Remedies. 
 If any Event of Default occurs and is continuing and is known to a responsible officer of the Trustee, the Trustee will send notice of the Event of Default to each Holder within 90 days after it occurs,
unless the Event of Default has been cured; provided that, except in the case of a default in the payment of the principal of or interest on any Note, the Trustee may withhold the notice if and so long as the board of directors, the executive
committee or a trust committee of directors of the Trustee in good faith determine that withholding the notice is in the interest of the Holders. 
 If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium, if any, and interest on the Notes or to enforce the performance
of any provision of the Notes or this Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the
Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by Law. 
 Section 6.04 Waiver of Past Defaults.

 Except as otherwise provided in this Indenture, the Majority Holders by written notice to the Trustee may on behalf of the
Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for
every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 

Section 6.05 Control by Majority. 
 The Majority Holders may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.
However, the Trustee may refuse to follow any direction that conflicts with applicable Law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of
other Holders not joining in the giving of such direction, and may take any other action it deems proper that is not inconsistent with any such direction received from Holders. 

  
 65 









 Section 6.06 Limitation on Suits. 

A Holder may not institute any proceeding, judicial or otherwise, with respect to this Indenture or the Notes, or for the appointment of
a receiver or Trustee, or for any other remedy under this Indenture or the Notes, unless: 
 (i) such Holder has
previously given to the Trustee written notice of a continuing Event of Default; 
 (ii) Holders of at least 25%
in aggregate principal amount of the Notes then outstanding voting as a single class have made written request to the Trustee to institute proceedings in respect of the Event of Default in its own name as Trustee under this Indenture; 

(iii) such Holder or Holders offer and, if requested, provide to the Trustee indemnity or security reasonably satisfactory
to the Trustee against any costs, liabilities or expenses to be incurred in compliance with such request; 
 (iv)
the Trustee within 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 
 (v) during such 60-day period, the Majority Holders have not given the Trustee a direction that is inconsistent with such written request. 

Notwithstanding anything to the contrary herein, the right of a Holder to receive payment of principal of or interest on its Note on or
after the Stated Maturities thereof, or to bring suit for the enforcement of any such payment on or after such dates, may not be impaired or affected without the consent of that Holder. 
 Section 6.07 Rights of Holders to Receive Payment. 
 Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of principal, premium, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or
to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder; provided that a Holder shall not have the right to institute any such suit for the
enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable Law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any Property
subject to such Lien. 
 Section 6.08 Collection Suit by Trustee. 
 If an Event of Default specified in Section 6.01(i) or (ii) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust
against the Issuer for the whole amount of principal of, premium, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

  
 66 









 Section 6.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have
the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuer (or
any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof and the Collateral Agent under
Section 10.11 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, the Collateral Agent and their respective agents and counsel, and any other amounts due the Trustee under
Section 7.06 hereof and the Collateral Agent under Section 10.11 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10 Priorities. 

If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order:

 First: to the Trustee, the Collateral Agent and the Offshore Accounts Bank and their respective agents

ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium, if any and interest, respectively; and 

Third: to the Issuer or to such party as a court of competent jurisdiction shall direct. 

The Trustee may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.10. 

Section 6.11 Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the
filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its 

  
 67 









 
discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal amount of the then outstanding Notes.

opinions to determine whether or not they conform to the form requirements of this Indenture and may rely on the advice of counsel to determine such conformance.

willful misconduct, except that: 
 (i) this paragraph does not limit the effect of paragraph (b) of this
Section 7.01;

Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel and the
advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. 

(c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of
any agent appointed with due care. 
 (d) The Trustee will not be liable for any action it takes or omits to take
in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture. 
 (e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Issuer will be sufficient if signed by an Authorized Officer of the Issuer. 

(f) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the
request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity or security satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such request or
direction. In no event shall the Trustee be obligated to expend or risk its own funds or incur any liabilities in the performance of its duties hereunder. 
 (g) In no event shall the Trustee be responsible or liable for any special indirect or consequential loss or damage of any kind whatsoever (including but not limited to, loss of profit), irrespective of
whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action. 
 Section 7.03
Individual Rights of Trustee. 
 Each of the Trustee and the Collateral Agent in its individual or any other capacity may become
the owner or pledgee of Notes and may otherwise deal with the Issuer, the Guarantors or any Affiliate of the Issuer with the same rights it would have if it were not Trustee or the Collateral Agent, as the case may be. However, in the event that the
Trustee or the Collateral Agent acquires any conflicting interest it must eliminate such conflict within 90 days or resign. Any Agent may do the same with like rights and duties. Each of the Trustee and the Collateral Agent is also subject to
Sections 7.09 and 7.10 hereof. 

  
 69 









 Section 7.04 Trustee’s Disclaimer. 

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it
shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any provision of this Indenture, it will not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture
other than its certificate of authentication. 
 Section 7.05 Notice of Defaults. 

If a Default or Event of Default occurs and is continuing and if it is actually known to the Trustee, the Trustee will mail to Holders of
Notes a notice of the Default or Event of Default within 90 days after it occurs (or promptly after its discovery if such discovery occurs 90 days after the Default or Event of Default). Except in the case of a Default or Event of Default in payment
of principal of, premium, if any or interest on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the
Notes. 
 Section 7.06 Compensation and Indemnity. 
 (a) The Issuer will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder; provided that the compensation set forth in any fee
letter shall be deemed reasonable. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Issuer will reimburse the Trustee promptly upon request for all disbursements, advances and
expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 

(b) The Issuer and the Guarantors will indemnify the Trustee, its Affiliates, and their respective officers, directors,
agents, employees and servants, against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of
enforcing this Indenture against the Issuer and the Guarantors (including this Section 7.06) and defending itself against any claim (whether asserted by the Issuer, the Guarantors, any Holder or any other Person) or liability in connection with
the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable to its gross negligence or willful misconduct. The obligation in the preceding sentence to indemnify
the Trustee shall not apply in connection with taxes incurred or owed as a result of the receipt by the Trustee of compensation for its services. The Trustee will notify the Issuer promptly of any claim for which it may seek indemnity. Failure by
the Trustee to so notify the Issuer will not relieve the Issuer or the Guarantors of their obligations hereunder. The Issuer or the Guarantors will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate
counsel, and the Issuer will pay the reasonable fees and expenses of such counsel. Neither the Issuer nor the Guarantors need pay for any settlement made without its consent, which consent will not be unreasonably withheld, delayed or conditioned.

 (c) The obligations of the Issuer and the Guarantors under this Section 7.06 will survive the
satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. 

  
 70 









 (d) To secure the Issuer’s and the Guarantors’ payment obligations
in this Section 7.06, the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien will survive the
satisfaction and discharge of this Indenture. 
 (e) When the Trustee incurs expenses or renders services after
an Event of Default specified in Section 6.01(v) or (vi) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration
under any Bankruptcy Law. 
 (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the
extent applicable. 
 Section 7.07 Replacement of Trustee. 

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the
successor Trustee’s acceptance of appointment as provided in this Section 7.07. The Issuer shall promptly appoint a successor Trustee provided, however, that in case of a bankruptcy, the resigning Trustee will have the right to appoint a
successor Trustee within 10 Business Days after giving such notice of resignation if the Issuer has not already appointed a successor Trustee. 
 (b) The Trustee may resign in writing at any time and be discharged by so notifying the Issuer. The Majority Holders may remove the Trustee by so notifying the Trustee and the Issuer in writing. The
Issuer may remove the Trustee if: 
 (i) the Trustee fails to comply with Section 7.09 hereof; 

(ii) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee
under any Bankruptcy Law; 
 (iii) a custodian or public officer takes charge of the Trustee or its property; or

 (iv) the Trustee becomes incapable of acting. 

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer will
promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee
appointed by the Issuer. 
 (d) If a successor Trustee does not take office within 60 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Issuer, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

 (e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails
to comply with Section 7.09 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer.
Thereupon, the resignation or removal of the retiring Trustee will become 

  
 71 









 
effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders. The
retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.06 hereof.
Notwithstanding replacement of the Trustee pursuant to this Section 7.07, the Issuer’s obligations under Section 7.06 hereof will continue for the benefit of the retiring Trustee. 

Section 7.08 Successor Trustee by Merger, etc. 
 If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will
be the successor Trustee. 
 Section 7.09 Eligibility; Disqualification. 

There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0
million as set forth in its most recent published annual report of condition. 
 This Indenture will always have a Trustee who
satisfies the requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). 
 Section 7.10
Preferential Collection of Claims Against Issuer. 
 The Trustee is subject to TIA § 311(a), excluding any creditor
relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 
 Section 7.11 Other Agents. 
 The rights, privileges, protections, immunities
and benefits given to the Trustee including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by each Agent and its respective officers, employees, agents, custodians and other Persons employed to act
hereunder. 
 ARTICLE 8 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01 Option to Effect Legal Defeasance or
Covenant Defeasance. 
 The Issuer may at any time, at the option of its Board of Directors evidenced by a resolution set forth
in an Officers’ Certificate, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. 

Section 8.02 Legal Defeasance and Discharge. 
 Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Project Parties will, subject to the satisfaction of the conditions set forth in
Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to the Financing Documents to which they are a party on the date the conditions set forth below are satisfied (hereinafter, “Legal
Defeasance”). 

  
 72 









 
For this purpose, Legal Defeasance means that the Issuer and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the
Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (i) and (ii) below, and each Project Party
will have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the
following provisions which will survive until otherwise terminated or discharged hereunder: 
 (i) the rights of
Holders of outstanding Notes to receive payments in respect of the principal of, or interest or premium, if any, on, such Notes when such payments are due from the trust referred to in Section 8.04 hereof; 

(ii) the Issuer’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof; 

(iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuer’s, Guarantors’
and such other Project Parties’ obligations in connection therewith; and 
 (iv) this Article 8. 

Subject to compliance with this Article 8, the Issuer may exercise its option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03 hereof. The exercise by the Issuer of Legal Defeasance pursuant to this Section 8.02 shall in each case be effective when 123 days have passed since the date of the deposit in trust in accordance
with the conditions set forth in Section 8.04 hereof. 
 Section 8.03 Covenant Defeasance. 

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, each of the Project
Parties will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations under the covenants contained in Sections 4.07 and 4.09 through 4.30 hereof (other than clause (i) of
Section 4.14 to the extent such clause relates to the Issuer) with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”),
and the Notes will thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be
deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and
the Note Guarantees, each Project Party may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except
as specified above, the remainder of this Indenture and such Notes and the Note Guarantees will be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(iii) through 6.01(xii) hereof will not constitute Events of Default. 

  
 73 









 Section 8.04 Conditions to Legal or Covenant Defeasance. 

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 

(i) the Issuer must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars,
non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants, to pay the principal of,
premium, if any, and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Issuer must specify whether the Notes are being defeased to such stated date for payment
or to a particular redemption date; 
 (ii) in the case of an election under Section 8.02 hereof, the Issuer
must deliver to the Trustee either a ruling received from the Internal Revenue Service or an Opinion of Counsel confirming that Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of the defeasance and
will be subject to federal income tax on the same amount and in the same manner and at the same times as would otherwise have been the case, which Opinion of Counsel could not be given absent a change of applicable U.S. federal income tax law after
the date of this Indenture; and 
 (iii) in the case of an election under Section 8.03 hereof, the Issuer
must deliver to the Trustee either a ruling received from the Internal Revenue Service or an Opinion of Counsel confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a
result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 

(iv) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a
Default or Event of Default resulting from the borrowing of funds to be applied to such deposit or the granting of any Lien to secure such borrowings) and the deposit will not result in a breach or violation of, or constitute a default under, any
other instrument to which the Issuer, the Guarantor or any other Project Party is a party or by which the Issuer, the Guarantor or any other Project Party is bound; 

(v) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default
under, any material agreement or instrument (other than this Indenture) to which the Issuer, the Guarantor or any other Project Party is a party or by which the Issuer, the Guarantor or any other Project Party is bound; 

(vi) the Issuer must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 8.05 Deposited Money
and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 8.06 hereof, all money
and non-callable government securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04
hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this 

  
 74 









 
Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and
to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 
 The Issuer will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable government securities deposited pursuant to Section 8.04
hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 

Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to the Issuer from time to time upon the
request of the Issuer any money or non-callable government securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(i) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

 Section 8.06 Repayment to Issuer. 
 Subject to applicable Law, any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest on, any Note and
remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) will be discharged from such trust; and the Holder of such
Note will thereafter be permitted to look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, will thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition),
notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the
Issuer. 
 Section 8.07 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable government securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or
judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then each Project Party’s obligations under this Indenture, the Notes and the Note Guarantees will be revived and reinstated as
though no deposit had occurred pursuant to Section 8.04 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.04 hereof, provided, however, that, if the Issuer makes
any payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations, the Issuer will be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent. 

  
 75

Collateral Agent may amend or supplement this Indenture, the Notes and the Note Guarantees without the consent of any Holder of Note:

Notes” section of the Offering Circular. 
 Upon the request of the Issuer accompanied by an Officers’ Certificate
certifying to the due authorization of the execution of any such amended or supplemental indenture or amendment or supplement to the Notes or the Note Guarantees, and upon receipt by the Trustee and the Collateral Agent, as applicable, of the
documents described in Section 7.02 hereof, the Trustee and, if applicable, the Collateral Agent will join with the Issuer and the Guarantors in the execution of any such document authorized or permitted by the terms of this Indenture and to
make any further appropriate agreements and stipulations that may be therein contained, but the Trustee or the Collateral Agent, as the case may be, will not be obligated to enter into such document that affects its own rights, duties or immunities
under this Indenture or otherwise. 
 Section 9.02 With Consent of Holders of Notes. 

(a) Except as provided below in this Section 9.02 and as otherwise provided in Article 6 hereof, the Issuer, the
Guarantor, the Trustee and the Collateral Agent may amend or supplement this Indenture, the Notes and the Note Guarantees with the written consent of the Majority Holders (in the case of the Collateral Agent, at the direction of the Trustee acting
on such Majority Holders’ consent) voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Section 6.07 hereof, any
existing Default or Event of Default or future compliance with any provision of this Indenture or the Notes may be waived with the written consent of the Majority Holders voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes are considered to be “outstanding” for purposes of this Section 9.02. 

  
 76

this Section 9.02, the Majority Holders voting as a single class may waive compliance in a particular instance by the Issuer, the Guarantor or any other Project Party with any provision of this Indenture, the Notes or the Note Guarantees.

 (c) Without the consent of each Holder affected, an amendment, supplement or waiver under this
Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

principal amount of or change the Stated Maturity of any installment of principal of any Note; 
 (ii) reduce the
rate of or change the Stated Maturity of any interest payment on any Note;

(ix) make any change in a Note Guarantee that would adversely affect the Holders. 

In addition, any amendment to, or waiver of, the provisions of this Indenture or any Security Document that has the effect of releasing
all or substantially all of the Collateral from the Liens securing the Notes will require the consent of the Holders of at least 75% in aggregate principal amount of the Notes then outstanding; provided, however, that (i) all
Collateral shall be released from the Liens securing the Notes pursuant to Articles 10 and 12 and (ii) all of the Alaskan Star Collateral shall be released from the Liens securing the Notes pursuant to Section 12.03. 

(d) Upon the request of the Issuer accompanied by an Officers’ Certificate certifying to the due authorization of the
execution of any such amended or supplemental indenture or amendment or supplement to the Notes or Note Guarantees, and upon the filing with the Trustee and the Collateral Agent, as applicable, of evidence satisfactory to the Trustee and the
Collateral Agent, as applicable, of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee and the Collateral Agent, as applicable, of the documents described in Section 7.02 hereof, the Trustee and, if applicable,


  
 77 









 
the Collateral Agent (acting at the direction of the Trustee), will join with the Issuer and the Guarantors in the execution of such amended or supplemental indenture or amendment or supplement
to the Notes or Note Guarantees unless such document directly affects the rights, duties or immunities of the Trustee or the Collateral Agent, as the case may be, under this Indenture or otherwise, in which case the Trustee or the Collateral Agent,
as the case may be, may in its discretion, but will not be obligated to, enter into such document. 
 (e) After
an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer will mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such
notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. 
 (f) It is not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent
approves the substance thereof. 
 Section 9.03 Revocation and Effect of Consents. 

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives
written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 

Section 9.04 Notation on or Exchange of Notes. 
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall, upon
receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make
the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 

Section 9.05 Trustee to Sign Amendments, etc. 
 The Trustee and the Collateral Agent, as applicable, will sign any amendment or supplement authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights,
duties, liabilities or immunities of the Trustee and the Collateral Agent, as applicable. In executing any amendment or supplement, the Trustee and the Collateral Agent, as applicable, will be entitled to receive and (subject to Section 7.01
hereof) will be fully protected in relying upon, in addition to the documents required by Section 13.03 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplement is authorized or
permitted by this Indenture and the Notes or Note Guarantees, if applicable. 
 Section 9.06 Payment. 

None of the Issuer or the Guarantors nor any of its Subsidiaries or Affiliates may, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any 

  
 78 









 
Holder for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or agreed to be
paid to all Holders that consent, waive or agree to amend such term or provision within the time period set forth in the solicitation documents relating to the consent, waiver or amendment.

applicable, in each case intended to be covered by any Security Document to which it is a party) is subject to a valid and enforceable first-priority Lien in favor of the Collateral Agent for the benefit of the Secured Parties (except as otherwise
permitted under the Financing Documents). In furtherance of the foregoing, (A) each of the Issuer and the Guarantors shall ensure that all of its after-acquired Property other than such Property not intended to be covered by such Security
Documents shall become subject to the Lien of the Security Documents having the priority contemplated thereby promptly upon the acquisition thereof and (B) each of the Issuer and the Guarantors shall not open or maintain any bank account (other
than each Guarantor’s Offshore Distribution Account) without first taking all such actions as may be necessary or otherwise requested by the Collateral Agent (acting at the instruction of the Trustee, who shall act as directed by the Majority
Holders) to ensure that such bank account is subject to a valid and enforceable first priority Lien in favor of the Collateral Agent for the benefit of the Secured Parties. 

(b) Each of the Issuer and the Guarantors shall take, or cause to be taken, all actions necessary to cause each Additional
Project Document intended to be covered by a Security Document 

  
 79 









 
to which it is a party to be or become subject to the Liens of the Security Documents (whether by amendment to any Security Document, execution of a new Security Document or otherwise) in favor
of the Collateral Agent, and shall deliver or cause to be delivered to the Collateral Agent such certificates or other documents with respect to each Additional Project Document as are necessary or as the Collateral Agent (acting at the instruction
of the Trustee, who shall act as directed by the Majority Holders) may reasonably request, in each case to the extent required by the Security Documents. 
 (c) Each of the Issuer and the Guarantors shall grant (and shall take all actions necessary to cause) a first priority Lien in favor of the Collateral Agent for the benefit of the Secured Parties on any
future Property, including Replacement Assets, of the Issuer or such Guarantor that is funded by any Net Available Amount or Net Disposition Proceeds, in each case to the extent required by the Security Documents. 

(d) On the Issue Date or at such other times as the Trustee may reasonably request in writing, each of the Issuer and the
Guarantors shall furnish, or cause to be furnished, to the Trustee and the Collateral Agent, an opinion or opinions of legal counsel either stating that, in the opinion of such counsel, such action has been taken with respect to (i) amending or
supplementing the Security Documents (or providing additional Security Documents, notifications or acknowledgments) as is necessary to subject all the Collateral (including any after-acquired Property of the Issuer or either Guarantors, as
applicable, in each case intended to be covered by a Security Document) to the Lien of the Security Documents and (ii)(A) the recordation of the Security Documents (including, without limitation, any amendment or supplement thereto) and any other
requisite documents and (B) the execution and filing of any financing statements and continuation statements as are necessary to maintain the Liens purported to be created by the Security Documents and reciting the details of such action taken
or to be taken or stating that, in the opinion of such counsel, no such action is necessary to maintain such Liens. Such opinion or opinions of counsel shall also describe the recordation of the Security Documents and any other requisite documents
and the execution and filing of any financing statements and continuation statements, or the taking of any other action that will, in the opinion of such counsel, be required to maintain the Liens purported to be created by the Security Documents
after the date of such opinion.

(a) The Collateral Agent shall not at any time release the Collateral from the Liens created by the Security Documents
unless such release is in accordance with the provisions of this Indenture and the applicable Security Documents. 
 (b) The release of any Collateral from the Liens created by the Security Documents shall not be deemed to impair the security under this Indenture in contravention of the provisions hereof if and to the
extent the Collateral is released pursuant to this Indenture and the Security Documents. 
 Section 10.04 Specified Releases of Collateral.

 (a) Collateral may be released from the Liens created by the Security Documents at any time or from time to time in

the consent of any Holder or the Trustee and at the expense of the Issuer or such other Project Party, shall execute, deliver or acknowledge such instruments or releases to evidence the release from the Liens created by the Security Documents of any
Collateral permitted to be released pursuant to this Indenture or the Security Documents. 
 Section 10.05 Release upon Satisfaction or
Defeasance of all Outstanding Obligations. 
 (a) The Liens on all Collateral that secure the Notes and the Note
Guarantees will be automatically terminated and released without the need for further action by any Person: 

(i) if the Issuer exercises Legal Defeasance or Covenant Defeasance as described under Section 8.01; 

(ii) upon satisfaction and discharge of this Indenture as described under Article 12; or 

(iii) upon payment in full in immediately available funds of the principal of, premium, if any, and accrued and unpaid

conditions precedent hereunder and under the Security Documents have been met, any necessary or proper instruments of termination, satisfaction or release prepared by the applicable Project Party, the Collateral Agent, without the consent of any
Holder or the Trustee and at the expense of the Issuer or such other Project Party, shall execute, deliver or acknowledge such instruments or releases to evidence the release from the Liens created by the Security Documents of any Collateral
permitted to be released pursuant to this Indenture or the Security Documents. 
 Section 10.06 Form and Sufficiency of Release.

 In the event that the Issuer, the Guarantors or any other Project Party has sold, exchanged, or otherwise disposed of or
proposes to sell, exchange or otherwise dispose of any portion of the Collateral that may be sold, exchanged or otherwise disposed of by the Issuer, the Guarantors or such other Project Party to any Person other than the Issuer or the Guarantors,

after satisfaction of the conditions set forth herein for delivery of any such release. Notwithstanding the preceding sentence, all purchasers and grantees of any property or rights purporting to be released herefrom shall be entitled to rely upon
any release executed by the Trustee or the Collateral Agent, as applicable, as sufficient for the purpose of this Indenture and as constituting a good and valid release of the property therein described from the Lien of this Indenture or of the
Security Documents. 

  
 81 









 Section 10.07 Purchaser Protected. 

No purchaser or grantee of any property or rights purported to have been released from the Lien of this Indenture or of the Security
Documents shall be bound to ascertain the authority of the Trustee or the Collateral Agent, as applicable, to execute the release or to inquire as to the existence of any conditions herein prescribed for the exercise of such authority; nor shall any
purchaser or grantee of any property or rights permitted by this Indenture to be sold or otherwise disposed of by the Issuer, the Guarantors or any other Project Party be under any obligation to ascertain or inquire into the authority of the Issuer
to make such sale or other disposition. 
 Section 10.08 Authorization of Actions to be Taken by the Collateral Agent Under the Security
Documents. 
 (a) Subject to the provisions of the applicable Security Documents, each Holder, by acceptance of
the Notes, and the Trustee hereby (i) appoints, designates and authorizes the Collateral Agent to take such action on its behalf under the provisions of this Indenture and each other Financing Document to which it is a party and to exercise
such powers and perform such duties as are expressly delegated to it by the terms of this Indenture or any such other Financing Document, together with such powers as are reasonably incidental thereto, (ii) to the extent required by the laws of
any jurisdiction for the purposes of the enforcement of any Collateral, shall assign to the Collateral Agent all its rights and interests to and under, the Financing Documents, on a free payment basis, for the exclusive purpose of allowing the
Collateral Agent to perform its powers and discretions under the Security Documents to which it is a party and (iii) authorizes the Collateral Agent to execute, deliver and perform each of the Financing Documents to which the Collateral Agent
is or is intended to be a party on its own behalf or on behalf of the Holders and the Trustee and each Holder agrees to be bound by all of the agreements of the Collateral Agent contained in such Financing Documents. 

(b) Notwithstanding any provision to the contrary contained elsewhere in this Indenture or in any other Financing
Document, the Collateral Agent shall not have any duties or responsibilities except those expressly set forth herein and in the other Financing Documents, nor shall Collateral Agent have or be deemed to have any fiduciary relationship with any
Holder or the Trustee, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture or any other Financing Document or otherwise exist against the Collateral Agent. Without limiting the
generality of the foregoing sentence, the use of the term “Collateral Agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency
doctrine of any applicable Law. Instead, such term is used merely as a matter of market custom, and are intended to create or reflect only a relationship between independent contracting parties. 

(c) So long as no Event of Default shall have occurred and be continuing, and subject to certain terms and conditions in
this Indenture and the Security Documents, the Project Parties will be entitled to exercise any voting, consensual rights and other rights pertaining to such Collateral pledged by it. Upon the occurrence and during the continuance of an Event of
Default, upon prior written notice and demand from the Collateral Agent, (a) all rights of the Project Parties to exercise such voting, consensual rights, or other rights shall cease and all such rights shall become vested in the Collateral
Agent, which, to the extent permitted by applicable Law, shall have the sole right to exercise such voting, consensual rights or other rights, (b) all rights of the Project Parties to receive cash dividends, interest and other payments made
upon or with respect to the Collateral shall cease, and such cash 

  
 82 









 
dividends, interest and other payments shall be paid to the Collateral Agent, for the benefit of the Secured Parties and (c) the Collateral Agent may sell the Collateral or any part thereof
in accordance with, and subject to the terms of, the Security Documents. All funds distributed in respect of the Collateral under the Security Documents and received by the Collateral Agent for the ratable benefit of the Secured Parties shall be
turned over to the Trustee to be distributed by it in accordance with the provisions of this Indenture. 
 (d)
Upon the occurrence and during the continuance of an Event of Default, the Collateral Agent (acting on the instructions of the Trustee, who shall act as directed by the Majority Holders) shall have the right to replace the Operating Company as
operator in accordance with the Services Agreements. 
 Section 10.09 Authorization of Receipt of Funds by the Trustee Under the Security
Documents. 
 The Collateral Agent is authorized to receive any funds for the benefit of itself, the Trustee and the Holders
distributed under the Security Documents and, to the extent not prohibited under the Security Documents or the applicable Accounts Agreement, to make further distributions of such funds to itself and the Trustee. The Trustee will make all
distributions to the Holders in accordance with the provisions of Section 6.10 and the other provisions of this Indenture. 

Section 10.10 Action by the Collateral Agent. 
 In each case that the Collateral Agent may or is required hereunder or under any Security Document to take any action (an “Action”), including without limitation to make any
determination, to give consents, to exercise rights, powers or remedies, to release or sell Collateral or otherwise to act hereunder or under any Security Document, the Collateral Agent may seek direction from the Majority Holders or from the
Trustee, who may seek direction from such Holders. The Collateral Agent shall not be liable with respect to any Action taken or omitted to be taken by it in accordance with the direction from the Majority Holders or the Trustee, as applicable. If
the Collateral Agent shall request direction from the Trustee, the Collateral Agent shall be entitled to refrain from such Action unless and until the Majority Holders have provided to the Collateral Agent an indemnification satisfactory to the
Collateral Agent, and the Collateral Agent shall not incur liability to any Person by reason of so refraining. 

Notwithstanding anything to the contrary in this Indenture or any Security Document, in no event shall the Collateral Agent or the
Trustee be responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or Liens intended to be created by this Indenture or the Security
Documents (including the filing or continuation of any Uniform Commercial Code financing or continuation statements or similar documents or instruments), nor shall the Collateral Agent or the Trustee be responsible for, and the Collateral Agent and
the Trustee make no representations regarding, the validity, effectiveness or priority of any of the Security Documents or the security interests or Liens intended to be created thereby. 

In the event that the Collateral Agent is required to acquire title to an asset, or take any managerial action of any kind in regard
thereto, in order to perform any obligation under this Agreement or any other Financing Document, which in the Collateral Agent’s sole discretion may cause the Collateral Agent to incur potential liability under any Environmental Law, the
Collateral Agent reserves the right, instead of taking such action, to either resign as the Collateral Agent or arrange for the transfer of the title or control of the asset to a court-appointed receiver. 

  
 83 









 Section 10.11 Compensation and Indemnity. 

(a) The Issuer will pay to the Collateral Agent, its Affiliates, and their respective officers, directors, agents,
employees and servants, from time to time reasonable compensation as shall be agreed to in writing by the Issuer and the Collateral Agent for its acceptance of this Indenture, the Security Documents and services hereunder. The Issuer will reimburse
the Collateral Agent promptly upon request for all reasonable and documented disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation,
disbursements and expenses of the Collateral Agent’s agents and counsel. 
 (b) The Issuer and the
Guarantors will, jointly and severally, indemnify the Collateral Agent against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture and
the Security Documents, including (i) any claim relating to the grant to the Collateral Agent of any Lien in any property or assets of the Issuer, either Guarantor or any other Project Party and (ii) the costs and expenses of enforcing
this Indenture and the Security Documents against the Issuer, the Guarantors and the Project Parties (including this Section 10.11) and defending itself against any claim (whether asserted by the Issuer, the Guarantors, any other Project Party,
any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder or thereunder, except to the extent any such loss, liability or expense may be attributable to its gross negligence
or willful misconduct as determined by a court of competent jurisdiction in a non-appealable order or judgment. The Collateral Agent will notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Collateral Agent to so
notify the Issuer will not relieve the Issuer, either Guarantor or each other Project Party party hereto of their obligations hereunder. The Issuer, the Guarantors or such Project Party will defend such claim and the Collateral Agent will cooperate
in the defense. The Collateral Agent may have separate counsel and the Issuer will pay the reasonable fees and expenses of such counsel. None of the Issuer, the Guarantors or any Project Party need pay for any settlement made without its consent,
which consent will not be unreasonably withheld, delayed or conditioned. 
 (c) Without in any way limiting the
generality of the other provisions contained in this Section 10.11, the Guarantors each agree to defend, protect, indemnify, save and hold harmless the Collateral Agent, its Affiliates, and their respective officers, directors, agents,
employees and servants, whether as beneficiary of any of the Security Documents, as a mortgagee in possession, or as successor-in-interest to the Guarantors by foreclosure deed or deed in lieu of foreclosure, or otherwise, from and against any and
all losses, liabilities or expenses incurred by it arising out of (A) the actual or alleged presence of Hazardous Materials on, in, under or affecting all or any portion of the Project whether or not the same originates or emanates from the
Project or from properties at which any Hazardous Materials generated, stored or handled by any Project Party were Released or disposed of, (B) any Environmental Claim relating to the Project or (C) the exercise of any Secured Party’s
rights under any of the provisions of the Security Documents (the “Indemnified Matters”), whether any of the Indemnified Matters arise before or after foreclosure of any of the Security Interests or other taking of title to all or
any portion of the Collateral by any Secured Party, including, without limitation, (x) the costs of removal of any and all Hazardous Materials from all or any portion of the Project, (y) additional costs required to take reasonable
precautions to protect against the Release of Hazardous Materials on, in, under or affecting the Project into the air, any body of water, any other public domain or any surrounding areas, and (z) costs incurred to comply, in connection with all
or any portion of the Project, with all applicable Environmental Laws with respect to Hazardous Materials, except to the extent that any such Indemnified Matter arises from the gross negligence or willful misconduct of such Indemnified Person, as
determined by a court of competent jurisdiction in a final non-appealable judgment. 

  
 84 









 (d) The obligations of the Issuer and the Guarantors under this
Section 10.11 will survive the satisfaction and discharge of this Indenture and the resignation, removal or replacement of the Collateral Agent. 
 (e) The Collateral Agent shall not incur any liability for not performing any act or fulfilling any duty, obligation or responsibility hereunder by reason of any occurrence beyond the control of the
Collateral Agent (including but not limited to any act or provision of any present or future law or regulation or governmental authority, any act of God or war, civil unrest, local or national disturbance or disaster, any act of terrorism, or the
unavailability of the Federal Reserve Bank wire or facsimile or other wire or communication facility). 
 Section 10.12 Delegation of
Duties of the Collateral Agent. 
 The Collateral Agent may execute any of its duties under this Indenture or any other
Financing Document by or through agents, employees or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Collateral Agent shall not be responsible for the negligence or misconduct of
any agent or attorney-in-fact that it selects with reasonable care. 
 Section 10.13 Liability of the Collateral Agent. 

The Collateral Agent shall not (a) be liable for any action taken or omitted to be taken by it under or in connection with this
Indenture or any other Transaction Document or the transactions contemplated hereby (except for its own gross negligence or willful misconduct), or (b) be responsible in any manner to any of the Holders or the Trustee or any other Person for
any recital, statement, representation or warranty made by the Issuer or any Affiliate of the Issuer, or any officer thereof, contained in this Indenture or in any other Transaction Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Indenture or any other Transaction Document, or for the value of or title to any Collateral, or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Transaction Document, or for any failure of the Issuer or any other party to any Transaction Document to perform its obligations hereunder or thereunder. The Collateral Agent shall not be
under any obligation to any Holder or the Trustee to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Indenture or any other Transaction Document, or to inspect the properties,
books or records of the Issuer or any Affiliate of the Issuer. 
 Section 10.14 Reliance by the Collateral Agent. 

The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, statement or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal
counsel (including counsel to the Issuer), independent accountants and other experts selected by the Collateral Agent. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Indenture or any
other Transaction Document in accordance with a request or consent of the Trustee and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the Holders and the Trustee. 

Section 10.15 Successor Collateral Agent. 
 (a) Subject to the appointment and acceptance of a successor as provided below, the Collateral Agent may resign at any time by giving notice thereof to the Trustee and the Issuer, and the


  
 85 









 
Collateral Agent may be removed on 30 days’ advance written notice with or without cause by the Majority Holders. Upon any such resignation or removal, the Majority Holders shall have the
right to appoint a successor to the Collateral Agent. If no successor Collateral Agent shall have been appointed, and shall have accepted such appointment within 30 days after the resigning Collateral Agent’s giving of notice of resignation or
the giving of any notice of removal thereof, then the resigning Collateral Agent or Collateral Agent being removed, as the case may be, may apply to a court of competent jurisdiction to appoint a successor thereto. If the Collateral Agent shall
resign or be removed pursuant to the foregoing provisions, upon the acceptance of appointment by a successor Collateral Agent hereunder, the former Collateral Agent shall deliver all Collateral then in its possession to the successor Collateral
Agent. Upon the acceptance of its appointment as a successor Collateral Agent hereunder, such successor Collateral Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of such resigning or removed
Collateral Agent, and such resigning Collateral Agent or removed Collateral Agent shall be discharged from its duties and obligations hereunder. Notwithstanding anything to the contrary hereunder or under any other Financing Document, a successor of
the Collateral Agent shall, to the extent required by applicable law, be a holder of all or part of the Obligations. 
 (b) After a Collateral Agent’s resignation or removal, the provisions of Section 10.11 and this Section 10.15 shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was the Collateral Agent. 
 ARTICLE 11 
 NOTE GUARANTEE 
 Section 11.01 Note Guarantee. 

(a) Subject to this Article 11, the Guarantors hereby jointly, severally, unconditionally and irrevocably guarantee to
each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, and to the Trustee, Collateral Agent and their respective successors and assigns, irrespective of the validity and enforceability of
this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that: 
 (i) the principal
of, premium, if any, and interest on, the Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, any
Additional Amounts required to be paid in connection with certain taxes, and all other Obligations of the Issuer to the Holders, the Trustee or the Collateral Agent under the Notes or the Indenture will be promptly paid in full or performed, all in
accordance with the terms hereof and thereof; and 
 (ii) in case of any extension of time of payment or renewal
of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. 

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will each be
obligated to pay the same immediately. The Guarantors agree that this is a guarantee of payment and not a guarantee of collection. 
 (b) The Guarantors hereby agree that its obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder of the Notes with respect to any 

  
 86 









 
provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable
discharge or defense of a guarantor. The Guarantors hereby waive diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the
Issuer, protest, notice and all demands whatsoever and covenant that this Note Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. 

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors or any
custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be
reinstated in full force and effect. 
 (d) Each of the Guarantors agrees that it will not be entitled to any
right of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby until payment in full of all Obligations guaranteed hereby. Each of the Guarantors further agrees that, as between either of the Guarantors, on the one
hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such Obligations (whether or not due
and payable) will forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. 

(e) The Note Guarantees will be senior secured obligations of the Guarantors, will rank equally with all other existing
unsubordinated obligations of the Guarantors, and will benefit from a first priority Lien on the Collateral as provided for herein; provided that, prior to the release of the Liens on the Existing Project Finance Collateral on or prior to the
Note Proceeds Account Release Date pursuant to the terms of this Indenture, the Existing Project Finance Secured Parties will have a prior claim on assets covered by the Liens on the Existing Project Finance Collateral. 

Section 11.02 Limitation on Guarantor Liability. 
 The Guarantors, and by its acceptance of Notes, each Holder, hereby confirm that it is the intention of all such parties that the Note Guarantees of the Guarantors not constitute a fraudulent transfer or
conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, state or foreign law to the extent applicable to any Note Guarantee. To effectuate the foregoing
intention, the Trustee, the Collateral Agent, the Holders and the Guarantors hereby irrevocably agree that the Obligations of the Guarantors will be limited to the maximum amount that will, after giving effect to such maximum amount and all other
contingent and fixed liabilities of the Guarantors that are relevant under such laws, result in the obligations of the Guarantors under their respective Note Guarantee not constituting a fraudulent transfer or conveyance. 

Section 11.03 Execution and Delivery of Note Guarantee. 
 To evidence its Note Guarantee set forth in Section 11.01 hereof, each of the Guarantors hereby agrees that a notation of such Note Guarantee substantially in the form attached as Exhibit E hereto
will be endorsed by an Authorized Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Authorized Officers. 

  
 87 









 Each of the Guarantors hereby agrees that its Note Guarantee set forth in
Section 11.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of the Note Guarantee. 
 If an Authorized Officer whose signature is on this Indenture or on the Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Note Guarantee is endorsed, the
Note Guarantee will be valid nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof
hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the Guarantors. 
 Section 11.04
Releases. 
 Upon Legal Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in
accordance with Article 12 hereof, Star International and/or Alaskan Star, as the case may be, will be released and relieved of any obligations under the Note Guarantee. 
 ARTICLE 12 
 SATISFACTION AND DISCHARGE 

Section 12.01 Satisfaction and Discharge. 
 This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when: 
 (i) either: 
 (a) all Notes that have been authenticated, except
lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Issuer, have been delivered to the Trustee for cancellation; or 

(b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the
mailing of a notice of redemption or otherwise or will become due and payable within one year and the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in
U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the
Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; 
 (ii) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such
deposit) and the deposit will not result in a breach or violation of, or constitute a default under, any other material instrument to which the Issuer, the Guarantors or any other Project Party is a party or by which the Issuer, the Guarantors or
any other Project Party is bound; 
 (iii) the Issuer, the Guarantors or any other Project Party has paid or
caused to be paid all sums payable by it under this Indenture; and 

  
 88 









 (iv) the Issuer has delivered irrevocable instructions to the Trustee under
this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be. 
 In
addition, the Issuer must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee and the Collateral Agent stating that all conditions precedent to satisfaction and discharge have been satisfied. 

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to
Section 12.01(i)(b), the provisions of Sections 12.02 and 8.06 hereof will survive. In addition, nothing in this Section 12.01 will be deemed to discharge those provisions of Section 7.06 hereof, that, by their terms, survive the
satisfaction and discharge of this Indenture. 
 Upon discharge of the Indenture in accordance with this Section 12.01, all
Note Guarantees shall automatically terminate and cease to be of effect. 
 Section 12.02 Application of Trust Money. 

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof shall
be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting as its own Paying Agent) as the Trustee may determine, to
the Persons entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law.

 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 12.01
hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Issuer and the Guarantors under this
Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01 hereof; provided that if the Issuer has made any payment of principal of, premium, if any, or interest on, any Notes
because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent. 

Section 12.03 Release of Liens on the Alaskan Star Collateral and the Note Guarantee by Alaskan Star. 

Notwithstanding any other provision contained in this Indenture, upon payment in full of all principal and accrued interest on the Notes
and any other amounts then due, in each case, payable by the Issuer under this Indenture on or before the Semi-Annual Payment Date occurring in November 2016 (including, without limitation, the installment of principal on the Notes due on such date
pursuant to the amortization schedule set forth on the Notes), Alaskan Star will be released and discharged from all its obligations in respect of its Note Guarantee and its obligation to indemnify the Trustee under this Indenture (the date such
releases and discharge occur, the “Alaskan Star Release Date”) by delivering a notice to the Trustee; provided, that: 
 (i) before and immediately after the release of the Liens on the Alaskan Star Collateral and Alaskan Star from its obligations pursuant to this Section 12.03, no Default or Event of Default shall
exist and any amounts due on the Notes and deferred as a result of a Deferral Event shall have been fully paid; 
 (ii) on the
Semi-Annual Payment Date occurring in November 2016 (after giving effect to the payment of any Obligations due on such date and the application of proceeds on deposit in the 

  
 89 









 
Offshore Proceeds Accounts), the amounts on deposit in the Offshore Debt Service Reserve Account shall be not less than the Offshore Debt Service Reserve Account Required Balance on such
Semi-Annual Payment Date; 
 (iii) on the Semi-Annual Payment Date occurring in November 2016 (after giving effect to the
payment of any Obligations and Operation and Maintenance Expenses due on such date and the application of proceeds on deposit in the Offshore Proceeds Accounts), the amounts on deposit in the Offshore O&M Service Reserve Account shall be not
less than the Offshore O&M Service Reserve Account Required Balance on such Semi-Annual Payment Date; 
 (iv) if, in order
to comply with the conditions set forth in clauses (ii) or (iii) above any of the Issuer or the Guarantors increases, at any time during the period from (and including) the Semi-Annual Payment Date occurring in May 2016 to (and including)
the Semi-Annual Payment Date occurring in November 2016 (or, in the case described in the proviso below clause (v), the period from (and including) the immediately preceding Semi-Annual Payment Date to (and including) the subsequent Semi-Annual
Payment Date referred to in such proviso), the amounts on deposit in either of the Offshore Debt Service Reserve Account or the Offshore O&M Service Reserve Account (a) with the proceeds of Permitted Equity Issuances or Permitted
Subordinated Indebtedness or (b) by crediting one or more Reserve Account Letters of Credit to either of such Guarantor Collateral Accounts, the Consolidated Historical Debt Service Coverage Ratio calculated on the Semester Date occurring in
November 2016, for the 12-month period ending on such Semester Date, shall be not less than 1.05:1.00; and 
 (v) immediately
after the release of the Liens on the Alaskan Star Collateral and Alaskan Star’s obligations pursuant to this Section 12.03, all Collateral (other than the Alaskan Star Collateral) shall remain subject to first priority Liens in favor of
the Collateral Agent for the benefit of the Secured Parties (to the extent necessary, by amendment of the Security Documents, by entering into new security documents or otherwise); 
 provided, that if the Alaskan Star Release Date does not occur due to the failure of the Issuer or the Guarantors to comply with the condition set forth in clause (iv) above, the Liens on the
Alaskan Star Collateral will be released and Alaskan Star will be released and discharged from all of its obligations in respect of its Note Guarantee and its obligation to indemnify the Trustee under this Indenture on any subsequent Semi-Annual
Payment Date; so long as on any such subsequent Semi-Annual Payment Date (a) all principal and accrued interest on the Notes and any other amounts then due, in each case, payable by the Issuer under this Indenture on or before such Semi-Annual
Payment Date (including, without limitation, the installment of principal on the Notes due on such date pursuant to the amortization schedule set forth in the Notes) shall have been paid in full and (b) each condition described in clauses
(i) to (v) above shall have been fulfilled as of such Semi-Annual Payment Date. 
 In connection with the release of
Alaskan Star from its obligations under the Note Guarantee to which it is a party, Alaskan Star shall have delivered to the Trustee a certificate of an Authorized Officer stating that all conditions precedent relating to the release of Alaskan
Star’s Note Guarantee have been complied with. Upon the release of Alaskan Star’s Note Guarantee, Alaskan Star will no longer be subject to any covenant or other provision of this Indenture or the Note Guarantee to which it is a party.

 Upon the request of the Alaskan Star pursuant to an Officers’ Certificate and Opinion of Counsel confirming that all
conditions precedent related to the release of the Alaskan Star Collateral have been met, the Collateral Agent, without the consent of any Holder or the Trustee and at the expense of the Issuer or any of the Guarantors, shall execute, deliver or
acknowledge such instruments or releases prepared by the Issuer or any Guarantor to evidence the release from the Liens created by the Security Documents of the Alaskan Star Collateral permitted to be released pursuant to this Section 12.03.

 The Issuer, the Guarantors, the Trustee or the Collateral Agent, by notice to the others, may designate additional or
different addresses for subsequent notices or communications. 
 All notices and communications (other than those sent to
Holders) will be deemed to have been duly given: at the time delivered by hand, if personally delivered; when mailed, postage prepaid, if mailed; when receipt acknowledged, if transmitted by facsimile; and the next Business Day after timely delivery
to the courier, if sent by overnight air courier guaranteeing next day delivery. 
 Any notice or communication to a Holder will
be mailed by first class mail, to its address shown on the register kept by the Registrar. Failure to mail a notice or communication to a Holder or any defect in it will not affect its sufficiency with respect to other Holders. Any notice to a
Holder of a Global Note shall be made in accordance with the rules of the Depositary. 
 If a notice or communication is mailed
in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it. 
 If the
Issuer mails a notice or communication to Holders, it will mail a copy to the Trustee and each Agent at the same time. 

Neither the failure to give any notice to a particular Holder, nor any defect in a notice given to a particular Holder, will affect the
sufficiency of any notice given to another Holder. 
 Notwithstanding any other provision of this Indenture or any Note, where
this Indenture or any Note provides for notice of any event (including any notice of redemption) to a Holder of a Global Note (whether by mail or otherwise), such notice shall be sufficiently given if given to the Depositary for such Note (or its
designee) pursuant to the standing instructions from such Depositary. For so long as the Notes are listed on the Euro MTF market of the Luxembourg Stock Exchange and it is required by the rules of the Luxembourg Stock Exchange, publication of such
notices to the Holders of the Notes in English in a leading newspaper having general circulation in Luxembourg (which is expected to be the d’Wort) or, to the extent and in the manner permitted by such rules, posted on the official
website of the Luxembourg Stock Exchange. 
 Section 13.02 Communication by Holders of Notes with Other Holders of Notes. 

Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the Notes.
The Issuer, the Trustee, the Registrar and anyone else shall have the protection of TIA § 312(c). 
 Section 13.03 Certificate and
Opinion as to Conditions Precedent. 
 Upon any request or application by the Issuer to the Trustee or the Collateral Agent to
take any action under this Indenture, the Issuer shall furnish to the Trustee: 
 (i) an Officers’
Certificate in form and substance reasonably satisfactory to the Trustee and, if applicable, the Collateral Agent (which must include the statements set forth in Section 13.04 hereof) stating that, in the opinion of the signers, all conditions
precedent and covenants, if any, provided for in this Indenture relating to the proposed action have been satisfied; and 

  
 92 









 (ii) an Opinion of Counsel in form and substance reasonably satisfactory to
the Trustee and, if applicable, the Collateral Agent (which must include the statements set forth in Section 13.04 hereof) stating that, in the opinion of such counsel, all such conditions precedent and covenants have been satisfied.

 Section 13.04 Statements Required in Certificate or Opinion.

(i) a statement that the Person making such certificate or opinion has read such covenant or condition; 

(ii) a brief statement as to the nature and scope of the examination or investigation upon which the statements or
opinions contained in such certificate or opinion are based; 
 (iii) a statement that, in the opinion of such
Person, he or she has made such examination or investigation as is necessary to enable him or her to express an informed opinion as to whether or not such covenant or condition has been satisfied; and 

(iv) a statement as to whether or not, in the opinion of such Person, such condition or covenant has been satisfied.

 Section 13.05 Rules by Trustee and Agents. 
 The Trustee may make reasonable rules for action by or at a meeting of Holders. The Registrar or Paying Agent may make reasonable rules and set reasonable requirements for its functions. 

Section 13.06 No Personal Liability of Directors, Officers, Employees and Stockholders. 

No past, present or future director, officer, employee, incorporator or stockholder of the Issuer, either Guarantor or any other Project
Party will have any liability for any obligations of the Issuer or the Guarantor under the Notes, this Indenture, the Note Guarantees or any other Financing Document or for any claim based on, in respect of, or by reason of, such obligations or
their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities
laws. 
 Section 13.07 No Immunity; No Liability. 
 (a) To the extent that any of the Issuer or the Guarantors may be entitled, in any jurisdiction in which judicial proceedings may at any time be commenced with respect to this Indenture, the Notes, the
Note Guarantee or any other Financing Document to which the Issuer or such Guarantor is a party, to claim for itself or its revenues, assets or Properties any immunity from suit, the jurisdiction of any court, attachment prior to judgment,
attachment in aid of execution of judgment, set-off, 

  
 93 









 
execution of a judgment or any other legal process, and to the extent that in any such jurisdiction there may be attributed to such Person such an immunity (whether or not claimed), each of the
Issuer and the Guarantors hereby irrevocably agrees not to claim and hereby irrevocably waives such immunity to the fullest extent permitted by the Law of the applicable jurisdiction. 

(b) No director, officer, employee, incorporator, member or stockholder of the Issuer or either Guarantor, as such, will
have any liability for any obligations of the Issuer or such Guarantor, as the case may be, under the Notes, the Note Guarantees or this Indenture or for any claim based on, in respect of, or by reason of, such obligations. Each Holder by accepting
a Note waives and releases all such liability. This waiver and release are part of the consideration for issuance of the Notes. This waiver may not be effective to waive liabilities under United States securities Laws, and it is the view of the U.S.
Securities and Exchange Commission that such a waiver is against public policy. 
 Section 13.08 Judgment Currency. 

Dollars are the sole currency of account and payment for all sums due and payable by the Issuer and the Guarantors under this Indenture,
the Notes and the Note Guarantees. If, for the purpose of obtaining judgment in any court, it is necessary to convert a sum due hereunder in Dollars into another currency, the Issuer and the Guarantors will agree, to the fullest extent that they may
legally and effectively do so, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Trustee determines a Person could purchase Dollars with such other currency in New York, New York, on the business
day immediately preceding the day on which final judgment is given. 
 The obligation of each of the Issuer and the Guarantors
in respect of any sum due to any Holder or the Trustee in Dollars shall, to the extent permitted by applicable Law, notwithstanding any judgment in a currency other than Dollars, be discharged only to the extent that on the business day following
receipt of any sum adjudged to be so due in the judgment currency such Holder or Trustee may in accordance with normal banking procedures purchase Dollars in the amount originally due to such Person with the judgment currency. If the amount of
Dollars so purchased is less than the sum originally due to such Person, each of the Issuer and the Guarantors agrees, jointly and severally, as a separate obligation and notwithstanding any such judgment, to indemnify such Person against the
resulting loss; and if the amount of Dollars so purchased is greater than the sum originally due to such Person, such Person will, by accepting a Note, be deemed to have agreed to repay such excess. 

Section 13.09 Submission to Jurisdiction; Appointment of Process Agent. 
 Each of the Issuer and the Guarantors hereby irrevocably submits to the non-exclusive jurisdiction of the U.S. federal and state courts in the Borough of Manhattan in the City of New York in any suit,
action or proceeding arising out of or relating to the Indenture or any Note or the Note Guarantees. Each of the Issuer and the Guarantors hereby irrevocably waives, to the fullest extent permitted by applicable Law, any objection which it may now
or hereafter have to the laying of venue of any such suit, action or proceeding brought in such courts and any claim that any such suit, action or proceeding brought in such courts, has been brought in an inconvenient forum and any right to which it
may be entitled on account of place of residence or domicile. To the extent the Issuer or either Guarantor has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process with respect to itself or its property,
each of the Issuer and the Guarantors hereby irrevocably waives such immunity in respect of (i) its obligations under this Indenture and (ii) any Note or the Note Guarantees. Each of the Issuer and the Guarantors hereby agrees that final
judgment in any such suit, action or proceeding brought in such a court shall be conclusive and binding on them and may be enforced in any court to the jurisdiction of which each of them is subject by a suit upon such judgment, provided, that
service of process is effected upon the Issuer or the Guarantors in the manner specified in the following paragraph or as otherwise permitted by applicable Law. 

  
 94 









 As long as any of the Notes remain outstanding, the Issuer and the Guarantors will at all
times have an authorized agent in the City of New York (the “Process Agent”), upon whom process may be served in any legal action or proceeding arising out of or relating to this Indenture or any Note or the Note Guarantees. Service
of process upon the Process Agent and written notice of such service mailed or delivered to the Issuer or either Guarantor shall to the extent permitted by applicable Law be deemed in every respect effective service of process upon the Issuer or
such Guarantor, as the case may be, in any such legal action or proceeding. The Issuer and the Guarantors will appoint National Registered Agents, Inc., 875 Avenue of the Americas, Suite 501, New York, New York 10001, United States (or at such other
address or at the office of such other authorized agent as the Issuer or the Guarantors may designate by written notice to the Trustee). 

Section 13.10 Governing Law. 
 THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES, AND THE NOTE GUARANTEES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE
EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 
 Section 13.11 Waiver of Jury Trial.

 EACH OF THE ISSUER, THE GUARANTORS, THE TRUSTEE AND THE COLLATERAL AGENT HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES, THE NOTE GUARANTEES, THE FINANCING DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY.

 Section 13.12 No Adverse Interpretation of Other Agreements. 
 This Indenture may not be used to interpret any other indenture, loan or debt agreement of the Issuer, the Guarantors or of any other Person. Any such indenture, loan or debt agreement may not be used to
interpret this Indenture. 
 Section 13.13 Successors. 
 All agreements of the Issuer and the Guarantors in this Indenture, the Notes, the Note Guarantees and each other Financing Document will bind its successors. All agreements of the Trustee and the
Collateral Agent in this Indenture will bind its successors. 
 Section 13.14 Severability. 

In case any provision in this Indenture, the Notes or the Note Guarantees is invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions will not in any way be affected or impaired thereby. 

  
 95 









 Section 13.15 Security Documents. 

The Trustee, the Collateral Agent and the Holders are bound by the terms of the Security Documents. 

Section 13.16 Counterpart Originals. 
 The parties may sign any number of copies of this Indenture. Each signed copy will be an original, but all of them together represent the same agreement. 

Section 13.17 Table of Contents, Headings, etc. 
 The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this
Indenture and will in no way modify or restrict any of the terms or provisions hereof.

certified English translation thereof. In the case of any Indenture Document originally issued in a language other than English, the English language version of any such Indenture Document shall for purposes of this Indenture, and absent manifest
error, control the meaning of the matters set forth therein. 
 Section 13.19 Patriot Act 

The parties hereto acknowledge that in accordance with the Uniting and Strengthening America by Providing Appropriate Tools Required to
Intercept and Obstruct Terrorism Act of 2001, Public Law 107-56 (the “Patriot Act”), the Trustee and the Collateral Agent, like all financial institutions, are required to obtain, verify, and record information that identifies each person

Guarantor Collateral Accounts on such date pursuant to the terms of the Guarantor Accounts Agreement (including, without limitation, pursuant to Section 6.1.2 of the Guarantor Accounts Agreement) the funds on deposit in the Note Debt Service Account
will not be sufficient to pay the full amount of principal on the Notes due on such Semi-Annual Payment Date (the amount of such shortfall, the “Shortfall Principal Amount”), then the Issuer shall be entitled to a one-time deferral
of the obligation to make the payment of the Shortfall Principal Amount, to be exercised by the Issuer in its sole discretion (such deferral, a “Deferral Event”). 

The Issuer will give the Trustee and the Collateral Agent written notice of the Deferral Event no earlier than 20 Business Days and no

the Guarantors (and, if necessary, the Issuer) shall deliver to the Collateral Agent irrevocable powers-of-attorney and such other documents as may be necessary to effect, upon instructions of the Trustee (acting upon the instructions of the
Majority Holders), the transfer under applicable Law of all right, title and interest in the Facilities for the Atlantic Star Drilling Rig and, unless previously released pursuant to Section 12.03 of the Indenture, the Alaskan Star Drilling Rig
to such transferee or transferees as the Trustee (acting upon the instructions of the 

  
 A-4









 
Majority Holders) may designate. Such powers-of-attorney and documentation shall be duly executed by each Guarantor (and, if necessary, the Issuer), to be held in escrow by the Collateral Agent.
If on the Original Maturity Date the aggregate amounts available on deposit in the Issuer’s Note Debt Service Account and the Guarantor Collateral Accounts (less the amounts necessary to pay all Operation and Maintenance Expenses and all
Obligations scheduled to become due prior to the Original Maturity Date) is less than the outstanding principal of and accrued and unpaid interest on the Notes due on the Original Maturity Date, then (a) the original Stated Maturity of the
Notes shall be automatically extended for a period of six months from the Original Maturity Date (such period being referred to as the “Initial Extension Period”), (b) the Collateral Agent shall be authorized as agent for the
Guarantors (and, if necessary, the Issuer), to the fullest extent permitted by applicable Law, to execute, deliver and file any and all documents, including any documents held in escrow by the Collateral Agent previously delivered to it by the
Guarantors (and, if applicable, the Issuer), to effect in good faith the transfer of title of the applicable Facilities to a transferee designated by the Trustee acting upon the instructions of the Majority Holders; and (C) the Issuer and the
Guarantors shall do and perform any and all acts (and execute any and all documents) as such Persons deem necessary (or as reasonably requested by the Trustee or the Collateral Agent) in order to effect such transfer; provided that, so long as no
Event of Default shall have occurred and be continuing, any such transfer described in this paragraph shall be made in consultation with the Issuer and the Guarantors. 
 On the last day of the Initial Extension Period, the Issuer shall apply all funds on deposit in the Note Debt Service Account pursuant to the Issuer Accounts Agreement to repay the remaining outstanding
principal amount of the Notes, together with interest accrued thereon and any other amounts payable under the Notes. 
 If, on
the last day of the Initial Extension Period, the aggregate amounts available on deposit in the Issuer’s Note Debt Service Account and the Guarantor Collateral Accounts (less the amounts necessary to pay all Operation and Maintenance Expenses
and all Obligations coming due prior to the end of the Initial Extension Period) is less than the outstanding principal of and accrued interest on the Notes due on the last day of the Initial Extension Period, the final maturity date of the Notes
shall be automatically extended for an additional period of six-months following the end of the Initial Extension Period, such additional extension period being referred to as the “Second Extension Period.” 

Upon a transfer of title to the Facilities as a result of an extension of the Original Maturity Date pursuant to this Section (iii), the
Trustee shall apply all of the net proceeds from such transfer to repay all of the then outstanding Obligations. If after the application of all such net proceeds all of the then outstanding Obligations have been repaid in full, then the Trustee
shall promptly transfer any remaining balance of such net proceeds to an account of the Guarantor that was the owner of the applicable Facilities, nominated by such Guarantor in writing to the Trustee and all the Liens on the Collateral other than
the Facilities shall be promptly released pursuant to the terms of the Indenture. 
 iv.
INTEREST. The Issuer promises to pay interest on the principal amount of this Note at 5.25 % per annum commencing on the Issue Date until, but not including, the Original Maturity Date. The Issuer will pay
interest semi-annually in arrears on May 30 and November 30 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue
from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a
record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be November 30,
2011. 

  
 A-5









 The Issuer will pay interest on the principal amount of this Note during the Initial
Extension Period (if any) at a rate per annum equal to the rate set forth on the face of this Note multiplied by 1.5 and during the Second Extension Period (if any) at a rate per annum equal to the rate set forth on the face of this Note multiplied
by 1.75. 
 The Issuer will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on
overdue principal and premium, if any, at the rate equal to 2.0% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful; it being understood, for the avoidance of doubt, that no such additional interest shall accrue with respect to
any Shortfall Principal Amount deferred as described in Section ii. 
 If the Issuer elects to defer any Shortfall Principal
Amount due on any Semi-Annual Payment Date, such Shortfall Principal Amount will (i) accrue interest at the per annum rate then applicable to the Notes and (ii) be due and payable on the next succeeding Semi-Annual Payment Date, together
with any interest accrued pursuant to clause (i). 
 Interest shall be computed on the basis of a 360-day year comprised of
twelve 30-day months. 
 v. METHOD OF PAYMENT. The Issuer will pay interest
on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the May 30 or November 30 next preceding the Interest Payment Date, even if such Notes are canceled after such record
date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the
Issuer maintained for such purpose or, at the option of the Paying Agent, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of
immediately available funds will be required with respect to principal of and interest, premium on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuer or the Paying Agent. Such
payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 
 vi. PAYING AGENT AND REGISTRAR. Initially, Deutsche Bank Trust Company Americas, the Trustee under the Indenture, will act as Paying
Agent and Registrar and Deutsche Bank Luxemburg S.A. will act as Luxembourg Paying Agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer may act in any such capacity. 

vii. INDENTURE. The Issuer issued the Notes under an Indenture dated as of July 27, 2011 (the
“Indenture”) among the Issuer, the Guarantors, the Collateral Agent, the Trustee and the Luxembourg Paying Agent. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the
TIA. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling. The Notes are secured obligations of the Issuer limited to $700.0 million in aggregate principal amount. 
 viii. OPTIONAL REDEMPTION. 

(a) At any time prior to November 30, 2016, the Issuer may on any one or more occasions redeem the Notes, at its
option, in whole or in part, at a “make-whole” redemption price 

  
 A-6









 
equal to the greater of (i) 101% of the principal amount of the Notes being redeemed and (ii) the present value at such redemption date of all required interest and principal payments
on such Notes through the final maturity date (excluding accrued but unpaid interest to the redemption date), discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate
plus 50 basis points; plus in each case any accrued and unpaid interest and Additional Amounts, if any, on such Notes to, but excluding, the redemption date, as calculated by the Independent Investment Banker. 

Any redemption of Notes by the Issuer pursuant to this Section (viii)(a) will be subject to either (A) there being at least
U.S.$150.0 million in aggregate principal amount of Notes outstanding after such redemption or (B) the Issuer redeeming all of the then-outstanding principal amount of the Notes. 
 “Comparable Treasury Issue” shall mean the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity
comparable to the remaining period until the final maturity date of the Notes that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable
maturity to the remaining period until the final maturity date of the Notes. 
 “Independent Investment Banker” shall mean one
of the Reference Treasury Dealers appointed by the Issuer. 
 “Comparable Treasury Price” shall mean, with respect to any
redemption date (i) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotation or (ii) if the Independent Investment Banker obtains
fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Reference Treasury Dealer”
shall mean Santander Investment Securities, Inc., HSBC Securities (USA) Inc., Citigroup Global Markets Inc. or their respective affiliates which are primary United States government securities dealers and not less than two other leading primary
United States government securities dealers in New York City reasonably designated by the Issuer; provided that if any of the foregoing cease to be a primary United States government securities dealer in New York City (a “Primary Treasury
Dealer”), the Issuer will substitute therefor another Primary Treasury Dealer. 
 “Reference Treasury Dealer Quotation”
shall mean, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked price for the Comparable Treasury Issue (expressed in each case as a percentage
of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 3:30 pm New York time on the third Business Day preceding such redemption date. 

“Treasury Rate” shall mean, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to
maturity or interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such
redemption date. 
 (b) On any Semi-Annual Payment Date occurring in November 2016 or at any time thereafter
until (but not including) the Semi-Annual Payment Date occurring in November 2017, the Issuer may redeem all, but not less than all, of the Notes, at a redemption price equal to 101% of the then outstanding principal amount of the Notes, plus
accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date). 

  
 A-7









 (c) On any Semi-Annual Payment Date occurring in November 2017 or at any
time thereafter, the Issuer may redeem all, but not less than all, of the Notes, at 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest and Additional Amounts, if any, to, but excluding, the redemption date
(subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date). 
 (d) If as a result of any change in or amendment to the applicable Laws of a Relevant Jurisdiction, or any amendment to or change in an official interpretation, administration or application of such Laws
(including a holding, judgment or order by a court of competent jurisdiction), which change or amendment or change in official position becomes effective on or after the Issue Date or on or, with respect to a successor, after the date a successor
assumes the obligations under the Notes, the Issuer, the Guarantors or any successor have or will become obligated to pay Additional Amounts, the Issuer may, at its option, redeem all, but not less than all, of the Notes, at a redemption price equal
to 100% of the principal amount of the Notes to be redeemed, together with accrued and unpaid interest, if any, to, but excluding, the applicable redemption date, upon publication of irrevocable notice not less than 30 days nor more than 60 days
prior to the applicable redemption date; provided that no notice of such redemption may be given earlier than 60 days prior to the earliest date on which the Issuer, the Guarantors or any successor would, but for such redemption, be obligated
to pay the Additional Amounts. Notwithstanding the foregoing, the Issuer shall not have the right to so redeem the Notes unless: (i) it has used commercially reasonable efforts to avoid the obligation to pay Additional Amounts; and (ii) it
has complied with all applicable Laws to legally effect such redemption; provided, however, that for this purpose commercially reasonable efforts shall not include, without limitation, any change in the Issuer’s or any successor’s,
corporate form, jurisdiction of incorporation or organization or location of its principal executive or registered office. In the event that the Issuer elects to so redeem the Notes, it will deliver to the Trustee: (1) a certificate of an
Authorized Officer of the Issuer stating that the Issuer is entitled to redeem the Notes pursuant to the indenture and setting forth a statement of facts showing that the condition or conditions precedent to the right of the Issuer to so redeem have
occurred or been satisfied; and (2) an opinion of counsel to the effect that the Issuer has or will become obligated to pay Additional Amounts and that all governmental approvals necessary for the Issuer to effect the redemption have been
obtained and are in full force and effect. 
 ix. MANDATORY REDEMPTION. If, as of the Note
Proceeds Account Release Date, (i) the Existing Project Finance Obligations are not repaid or purchased by the Issuer in full or (ii) all funds on deposit in the Note Proceeds Account are not released, then the Issuer shall instruct the
Collateral Agent to disburse all funds then held on deposit in the Note Proceeds Account to the Trustee and redeem the maximum principal amount of Notes, together with accrued and unpaid interest, if any, thereon to, but excluding, the applicable
redemption date (subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date) that may be redeemed with the funds then held on deposit in the Note Proceeds Account, at a redemption price
equal to 100% of the principal amount of the Notes to be redeemed, together with accrued and unpaid interest, if any, thereon to, but excluding, the applicable redemption date. 

x. OFFERS TO PURCHASE. 

(a) A Holder may tender all or any portion of its Notes pursuant to an Offer to Purchase; provided that, to the extent any Holder
tenders less than all of its Notes, any Note that is not tendered must be for a minimum denomination of $200,000; provided, further, that any portion of a Note tendered pursuant to an Offer to Purchase must be in a multiple of $1,000
principal amount. 
 (b) On the Offer Purchase Date, the purchase price specified in the written offer will become due and
payable on each Note accepted for purchase pursuant to the Offer to Purchase, and interest on Notes purchased pursuant to such Offer to Purchase will cease to accrue on and after the Offer Purchase Date. 

  
 A-8









 (c) If (i) the Issuer makes an Offer to Purchase for less than all of the outstanding
Notes and (ii) Notes in an aggregate principal amount in excess of the purchase amount specified in the written offer are tendered and not withdrawn pursuant to the Offer to Purchase, then the Issuer will purchase Notes having an aggregate
principal amount equal to the purchase amount specified on the written offer on a pro rata basis; provided that adjustments shall be made so that only Notes in multiples of $1,000 principal amount will be purchased. 

(d) Any Offer to Purchase shall be made by the Issuer in compliance with Rule 14e-1 under the Exchange Act (to the extent applicable)
and all other applicable Laws, and the procedures set forth in the Indenture shall be deemed to be modified as necessary to permit such compliance. The Issuer and Guarantors shall additionally obtain all necessary consents and approvals from any
Governmental Authority for any required remittance of funds outside of any jurisdiction in connection with any Offer to Purchase pursuant to the Indenture. 
 (e) Notwithstanding anything herein to the contrary, the Issuer shall not be required to make an Offer to Purchase pursuant to the terms of Section 3.09, 4.10(c), 4.15 or 4.19(b) of the Indenture if
(i) a third party makes an offer to purchase Notes in the manner, at the times and otherwise in compliance with the requirements set forth in Section 3.09 of the Indenture applicable to an Offer to Purchase made by the Issuer and such
third party purchases all Notes properly tendered and not withdrawn by the Holders thereof under such offer to purchase or (ii) if notice of redemption for all outstanding Notes has been given pursuant to Section 3.07 or 3.08 of the
Indenture, unless and until there is a default in payment of the applicable redemption price. 
 xi. NOTICE
OF REDEMPTION. At least 30 days but not more than 60 days before a redemption date, the Issuer will mail or cause to be mailed, by first class mail, postage prepaid, a notice of redemption to the
Trustee and to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a
satisfaction and discharge of the Indenture pursuant to Articles 8 or 12 thereof. Notes in denominations larger than $2,000 may be redeemed in part but only in amounts of $200,000 or whole multiples of $1,000, unless all of the Notes held by a
Holder are to be redeemed. 
 xii. DENOMINATIONS, TRANSFER,
EXCHANGE. The Notes are in registered form without coupons in denominations of $200,000 and integral multiples of $1,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the
Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. Neither the Issuer nor the Registrar will be required (i) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for
redemption under Section 3.02 of the Indenture and ending at the close of business on the day of selection; (ii) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion
of any Note being redeemed in part; or (iii) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date. 
 xiii. PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes. 

  
 A-9









 xiv. AMENDMENT, SUPPLEMENT AND
WAIVER. Subject to certain exceptions, the Indenture, the Notes, the Note Guarantees and the other Financing Documents may be amended or supplemented with the consent of the Holders (or in the case of the Collateral Agent, if
applicable, at the direction of the Trustee acting on such Holders’ consent) of at least a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 of the Indenture, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the
principal of, premium, if any, or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders
of a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Without the
consent of any Holder of a Note, the Indenture, the Notes, the Note Guarantees and the other Financing Documents may be amended or supplemented to cure any ambiguity, defect or inconsistency in a manner that does not materially and adversely affect
the rights of any Holder, to evidence and provide for the acceptance of an appointment of a successor Trustee, to provide for uncertificated Notes in addition to or in place of certificated Notes, to provide for any Note Guarantee, to secure the
Notes or to confirm and evidence the release, termination or discharge of any Note Guarantee of or Lien on Collateral Securing the Notes when such release, termination or discharge is permitted by the Indenture, to given effect to any Permitted
Reorganization or Existing Project Finance Loan Purchase to the extent permitted by the Indenture, or to make any other change that does not materially and adversely affect the rights under the Indenture of any Holder or to conform the text of the
Indenture to any provision of the “Description of Notes” section of the Offering Circular. 
 xv.
DEFAULTS AND REMEDIES. Events of Default are set forth in Section 6.01 of the Indenture. In the case of an Event of Default specified in clause (v) or (vi) of Section 6.01 of the
Indenture, with respect to the Issuer or the Guarantor, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least
25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Holders of a majority in aggregate
principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. 
 If any Event of
Default occurs and is continuing and is known to a responsible officer of the Trustee, the Trustee will send notice of the Event of Default to each Holder within 90 days after it occurs, unless the Event of Default has been cured; provided
that, except in the case of a default in the payment of the principal of or interest on any Note, the Trustee may withhold the notice if and so long as the board of directors, the executive committee or a trust committee of directors of the Trustee
in good faith determine that withholding the notice is in the interest of the Holders. 
 Except as otherwise provided in this
Indenture, the Majority Holders by written notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the
payment of the principal of, premium, if any, or interest on, the Notes (including in connection with an Offer to Purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may
rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. The Majority Holders by written notice to the Issuer and to the Trustee may, on behalf of all of the Holders, rescind and annul
a declaration of acceleration and its consequences if (i) all existing Events of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by the declaration of acceleration,
have been cured or waived; and (ii) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. No such rescission shall affect any subsequent Default or impair any right consequent thereto. 

  
 A-10









 The Issuer is required to deliver to the Trustee within 120 days after the end of each
fiscal year commencing with the fiscal year ending December 31, 2011, an Officers’ Certificate regarding compliance with the Indenture, and the Issuer is required, upon becoming aware of any Default or Event of Default, to deliver to the
Trustee an Officers’ Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto. 
 xvi. TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Issuer or its Affiliates, and may otherwise deal with the Issuer or its Affiliates, as if it were not the Trustee. However, in the event that the Trustee or the Collateral Agent acquires any conflicting interest it must
eliminate such conflict within 90 days or resign. 
 xvii. NO RECOURSE AGAINST
OTHERS. A director, officer, employee, incorporator or stockholder of the Issuer or either the Guarantor, as such, will not have any liability for any obligations of the Issuer or either Guarantor under the Notes, the Indenture or
the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the
issuance of the Notes. The waiver may not be effective to waive liabilities under the federal securities laws, and it is the view of the U.S. Securities and Exchange Commission that such a waiver is against public policy. 

xviii. AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or
an authenticating agent. 
 xix. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act).

 xx. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security
Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers
either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon. 
 xxi. GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THE INDENTURE, THIS NOTE, AND THE NOTE GUARANTEE WITHOUT GIVING
EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.
