SECTION 3. Additional Covenants. Each of the Company and the Guarantors further covenants and agrees with each Initial Purchaser as follows:

(a) Preparation of Offering Circular; Initial Purchasers’ Review of Proposed Amendments and Supplements and Company Additional Written Communications. As promptly as practicable following the Time of Sale and in any event not later than the second business day following the date hereof, the Company will prepare and deliver to the Initial Purchasers the Offering Circular. The Company will not amend or supplement the Preliminary Offering Circular (except via the Pricing Supplement) or the Pricing Supplement. The Company will not amend or supplement the Offering Circular prior to the Closing Date unless the Representative shall previously have been furnished a copy of the proposed amendment or supplement at least one business day prior to the proposed use or filing, and shall not have objected to such amendment or supplement. Before making, preparing, using, authorizing, approving or distributing any Company Additional Written Communication, the Company will furnish to the Representative a copy of such written communication for review and will not make, prepare, use, authorize, approve or distribute any such written communication to which the Representative reasonably objects.

(b) Amendments and Supplements to the Offering Circular and Other Securities Act Matters. If at any time prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which any of the Pricing Disclosure Package as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (ii) it is necessary to amend or supplement any of the Pricing Disclosure Package to comply with law, the Company and the Guarantors will immediately notify the Initial Purchasers thereof and forthwith prepare and (subject to Section 3(a) hereof) furnish to the Initial Purchasers such amendments or supplements to any of the Pricing Disclosure Package as may be necessary so that the statements in any of the Pricing Disclosure Package as so amended or supplemented will not, in the light of the circumstances under which they were made, be misleading or so that any of the Pricing Disclosure Package will comply with all applicable law. If, prior to the completion of the placement of the Securities by the Initial Purchasers with the Subsequent Purchasers, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Offering Circular, as then amended or supplemented, in order to make the statements therein, in the light of the circumstances existing when the Offering Circular is delivered to a Subsequent Purchaser, not misleading, or if in the judgment of the Initial Purchasers or counsel for the Initial Purchasers it is otherwise necessary to amend or supplement the Offering Circular to comply with applicable law, the Company and the Guarantors agree to promptly prepare (subject to Section 3 hereof), and furnish at their own expense to the Initial Purchasers, amendments or supplements to the Offering Circular so that the statements in the Offering Circular as so amended or supplemented will not, in the light of the circumstances at the Closing Date and at the time of sale of the Securities, be misleading or so that the Offering Circular, as amended or supplemented, will comply with all applicable law.

The Company hereby expressly acknowledges that the indemnification and contribution provisions of Sections 8 and 9 hereof are specifically applicable and relate to each offering memorandum, amendment or supplement referred to in this Section 3.

(c) Copies of the Pricing Disclosure Package and the Offering Circular. The Company agrees to furnish the Initial Purchasers, without charge, as many copies of the Pricing Disclosure Package and the Offering Circular and any amendments and supplements thereto as they shall reasonably request.

None of the Company or any of the Guarantors shall be required to qualify as a foreign corporation or other entity or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation. The Company will advise the Representative promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, each of the Company and the Guarantors shall use its commercially reasonable efforts to obtain the withdrawal thereof at the earliest possible moment.

(e) Use of Proceeds. The Company shall apply the net proceeds from the sale of the Securities sold by it in the manner described under the caption “Use of Proceeds” in the Pricing Disclosure Package.

Additionally, at any time prior to the completion of the placement of the Securities by the Initial Purchasers with the Subsequent Purchasers when the Company is not subject to Section 13 or 15 of the Exchange Act and the Securities are “restricted securities” within the meaning of Rule 144 under the Securities Act, for the benefit of holders and beneficial owners from time to time of the Securities, the Company shall furnish, at its expense, upon request, to holders and beneficial owners of Securities and prospective purchasers of Securities information (“Additional Issuer Information”) satisfying the requirements of Rule 144A(d).

(h) Agreement Not To Offer or Sell Additional Securities. During the period of 90 days following the date hereof, the Company will not, without the prior written consent of the Representative (which consent may be withheld at the sole discretion of the Representative), directly or indirectly, sell, offer, contract or grant any option to sell, pledge, transfer or establish an open “put equivalent position” within the meaning of Rule 16a-1 under the Exchange Act, or otherwise dispose of or transfer, or announce the offering of, any debt securities of the Company or securities exchangeable for or convertible into debt securities of the Company (other than as contemplated by this Agreement); provided, that the Company may file with the Commission one or more universal shelf registration statements under the Securities Act.

(i) No Integration. The Company agrees that it will not and will cause its Affiliates not to make any offer or sale of securities of the Company of any class if, as a result of the doctrine of “integration” referred to in Rule 502 under the Securities Act, such offer or sale would render invalid (for the purpose of (i) the sale of the Securities by the Company to the Initial Purchasers, (ii) the resale of the Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the Securities by such Subsequent Purchasers to others) the exemption from the registration requirements of the Securities Act provided by Section 4(2) thereof or by Rule 144A or by Regulation S.

(j) No General Solicitation or Directed Selling Efforts.

(k) No Restricted Resales. During the period of six months after the Closing Date, the Company will not, and will use commercially reasonable efforts not to permit any of its affiliates (as defined in Rule 144 under the Securities Act) to resell any of the Notes that have been reacquired by any of them.

(l) Legended Securities. Each certificate for a Security will bear the legend contained in “Transfer Restrictions” in the Preliminary Offering Circular for the time period and upon the other terms stated in the Preliminary Offering Circular.

(m) No Stabilization. The Company, the Guarantors and their respective Affiliates will not take, directly or indirectly, any action designed to or that reasonably would be expected to cause or result in the stabilization or manipulation of the price of the Securities.

The Representative, on behalf of the several Initial Purchasers may, in its sole discretion, waive in writing the performance by the Company or any Guarantor of any one or more of the foregoing covenants or extend the time for their performance.

The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company may otherwise have.

(b) Indemnification of the Company and the Guarantors. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each Guarantor, each of their respective directors, officers and employees and each person, if any, who controls the Company or any Guarantor within the meaning of the Securities Act or the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Company, any Guarantor or any such director, officer, employee or controlling person may become subject, under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Circular, the Pricing Supplement, any Company Additional Written Communication or the Offering Circular (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or

alleged untrue statement or omission or alleged omission was made in the Preliminary Offering Circular, the Pricing Supplement, any Company Additional Written Communication or the Offering Circular (or any amendment or supplement thereto), in reliance upon and in conformity with written information furnished to the Company by such Initial Purchaser through the Representative expressly for use therein; and to reimburse the Company, any Guarantor and each such director or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Company, any Guarantor or such director or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the Company and the Guarantors hereby acknowledges that the only information that the Initial Purchasers through the Representative have furnished to the Company expressly for use in the Preliminary Offering Circular, the Pricing Supplement, any Company Additional Written Communication or the Offering Circular (or any amendment or supplement thereto) are the statements set forth in the third sentence of the second full paragraph, the second sentence of the seventh full paragraph, the eighth full paragraph and the fourth sentence of the tenth paragraph under the caption “Plan of Distribution” in the Preliminary Offering Circular and the Offering Circular. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; provided that the failure to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 8 except to the extent that it has been materially prejudiced by such failure (through the forfeiture of any substantive rights or defenses) and the operation of this provision shall not relieve the indemnifying party from any liability that the indemnifying party may have to an indemnified party other than under this Section 8. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to

the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any special, local and conflicts counsel in each relevant jurisdiction), which shall be selected by the Representative (in the case of counsel representing the Initial Purchasers or their related persons), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the reasonable fees and expenses of outside counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which will not be unreasonably withheld, but if settled with such consent or if there be a final judgment (other than a final judgment entered into pursuant to a settlement as to which the indemnifying party did not consent) for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel as contemplated by this Section 8, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

SECTION 9. Contribution. If the indemnification provided for in Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantors, on the one hand, and the

Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities. The relative fault of the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantors, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or inaccuracy.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8 hereof, any out-of-pocket legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8 hereof for purposes of indemnification.

The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the discount received by such Initial Purchaser in connection with the Securities distributed by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each director, officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director of the Company or any Guarantor, and each person, if any, who controls the Company or any Guarantor with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Company and the Guarantors.

SECTION 10. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representative by notice given to the Company if at any time: (i) trading in any of the Company’s securities shall have been suspended or materially limited by the Commission or by the New York Stock Exchange (the “NYSE”), or trading in securities generally on the NYSE shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on such stock exchange by the

Commission or FINRA; (ii) a general banking moratorium shall have been declared by any of federal or New York authorities; (iii) there shall have occurred any outbreak or material escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representative is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities in the manner and on the terms described in the Pricing Disclosure Package or to enforce contracts for the sale of securities; or (iv) in the judgment of the Representative there shall have occurred any Material Adverse Effect, the effect of which, in the judgment of the Representative, makes it impracticable or inadvisable to proceed with the offering sale or delivery of the Securities in the manner and on the terms described in the Pricing Disclosure Package. Any termination pursuant to this Section 10 shall be without liability on the part of (i) the Company or any Guarantor to any Initial Purchaser, except that the Company and the Guarantors shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof, (ii) any Initial Purchaser to the Company, or (iii) any party hereto to any other party except that the provisions of Sections 8 and 9 hereof shall at all times be effective and shall survive such termination.

SECTION 11. Representations and Indemnities to Survive Delivery. The respective indemnities, representations and warranties of the Company, the Guarantors, their respective officers and the several Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect (in each case, until the expiration of the applicable statutes of limitation), regardless of any investigation made by or on behalf of any Initial Purchaser, the Company, any Guarantor or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and, except as otherwise provided herein, any termination of this Agreement.

SECTION 12. Notices. All communications hereunder shall be in writing and shall be mailed, hand delivered, couriered or facsimiled and confirmed to the parties hereto as follows:

Any party hereto may change the address or facsimile number for receipt of communications by giving written notice to the others.

SECTION 13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto, and to the benefit of the indemnified parties referred to in Sections 8 and 9 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder. The term “successors” shall not include any Subsequent Purchaser or other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase.

SECTION 14. Authority of the Representative. Any action by the Initial Purchasers hereunder may be taken by the Representative on behalf of the Initial Purchasers, and any such action taken by the Representative shall be binding upon the Initial Purchasers.

SECTION 15. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

SECTION 16. Governing Law Provisions. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE WITHOUT REGARD TO ANY CONFLICTS OF LAW PRINCIPLES THEREOF THAT WOULD RESULT IN THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION.

(a) Agent for Service of Process. By the execution and delivery of this Agreement, each of the Company and the Guarantors (i) acknowledges that it hereby irrevocably designates and appoints McDermott, Inc. (together with any successor, the “Agent for Service”) as its authorized agent upon which process may be served in legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) that may be instituted in any Specified Court (as defined below), and acknowledges that the Agent for Service has accepted such designation and appointment.

(b) Consent to Jurisdiction. Any Related Proceedings may be instituted in the Specified Courts, federal courts of the United States of America located in the City and County of New York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for suits, actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding a “Related Judgment”, as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any Specified Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum.

(c) Waiver of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

(d) Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than U.S. dollars, the parties hereto agree, to the fullest extent that they may effectively do so, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Initial Purchasers could purchase U.S. dollars with such other currency in The City of New York on the business

day preceding that on which final judgment is given. The obligations of the Company and each Guarantor in respect of any sum due from them to the Initial Purchasers shall, notwithstanding any judgment in any currency other than U.S. dollars, not be discharged until the first business day, following receipt by the Initial Purchasers of any sum adjudged to be so due in such other currency, on which (and only to the extent that) the Initial Purchasers may in accordance with normal banking procedures purchase U.S. dollars with such other currency; if the U.S. dollars so purchased are less than the sum originally due to the Initial Purchasers hereunder, the Company and each Guarantor agrees, as a separate obligation and notwithstanding any such judgment, to indemnify each Initial Purchaser against such loss. If the U.S. dollars so purchased are greater than the sum originally due to the Initial Purchasers hereunder, each Initial Purchaser agrees to pay to the Company and the Guarantors (but without duplication) an amount equal to the excess of the U.S. dollars so purchased over the sum originally due to such Initial Purchaser hereunder.

SECTION 17. Default of One or More of the Several Initial Purchasers. If any one or more of the several Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the number of Securities set forth opposite their respective names on Schedule A bears to the aggregate number of Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Purchasers agreed but failed or refused to purchase on the Closing Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the aggregate number of Securities with respect to which such default occurs exceeds 10% of the aggregate number of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Company for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination; but nothing herein shall relieve a defaulting Initial Purchaser from liability for its default and a defaulting Initial Purchaser shall not be entitled to reimbursement of expenses pursuant to Section 6 hereof. In any such case either the Initial Purchasers or the Company shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Offering Circular or any other documents or arrangements may be effected.

As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 17. Any action taken under this Section 17 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

SECTION 18. No Advisory or Fiduciary Responsibility. Each of the Company and the Guarantors acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Guarantors, on the one hand, and the several Initial Purchasers, on the other

hand, and the Company and the Guarantors are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Company and the Guarantors or their respective affiliates, stockholders, creditors or employees; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Company and the Guarantors with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Company and the Guarantors on other matters) or any other obligation to the Company and the Guarantors except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Guarantors and that the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the several Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Company and the Guarantors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate. The Company and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that the Company and the Guarantors may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Guarantors and the several Initial Purchasers, or any of them, with respect to the subject matter hereof.

SECTION 19. General Provisions. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by telecopier, facsimile or other electronic transmission (i.e., a “pdf” or “tif”) shall be effective as delivery of a manually executed counterpart thereof. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to the Company the enclosed copies hereof, whereupon this instrument, along with all counterparts hereof, shall become a binding agreement in accordance with its terms.

	Title:	Attorney-in-fact

The foregoing Purchase Agreement is hereby confirmed and accepted by the several Initial Purchasers as of the date first above written.

We have acted as Panamanian counsel to McDermott International, Inc., a Panamanian corporation (the “Company”), and the Panamanian Guarantors listed in Schedule A hereto, in connection with the issue and sale to the several initial purchasers named on Schedule A to the Purchase Agreement (the “Initial Purchasers”) acting severally and not jointly, of US$[500,000,000.00] aggregate principal amount of the Company’s [ ]% Senior Secured Notes due 2021 (the “Notes”). Goldman, Sachs & Co. (“GS”) has agreed to act as the representative of the several Initial Purchasers (the “Representative”) in connection with the offering and sale of the Notes.

The Securities (as defined below) will be issued pursuant to an indenture, to be dated as of April [ ], 2014 (the “Indenture”), among the Company, the Guarantors (as defined below) and Wells Fargo Bank, National Association, as trustee (the “Trustee”). Securities will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”) pursuant to a letter of representations, to be dated on or before the Closing Date (as defined in Section 2 hereof) (the “DTC Agreement”), between the Company and the Depositary.

The payment of principal, of premium, if any, and interest on the Notes will be fully and unconditionally guaranteed on a senior secured basis, jointly and severally by the entities listed on the signature pages of the Purchase Agreement (collectively, the “Guarantors”), pursuant to their guarantees (the “Guarantees”). The Notes and the Guarantees attached to the Purchase Agreement are herein collectively referred to as the “Securities.”

In addition, the Notes will be secured, subject to permitted liens as described under the caption “Description of the Notes” in the Pricing Disclosure Package and the Offering Circular, by liens on the assets of the Company and the Guarantors, as more particularly described in the Pricing Disclosure Package and documented, among others, by the “Panamanian Mortgages” described in Schedule B attached hereto.

In their capacity as owners of the Panamanian vessels described in Schedule C attached hereto, Hydro Marine Services, Inc., a Panamanian corporation (“Hydro Marine”) and J. Ray McDermott International Vessels, Ltd., a Cayman Islands company (“JRMIVL”), will be referred to collectively as the “Panamanian Vessel Owners”.

This opinion is being delivered to you pursuant to Section 5(c) of the Purchase Agreement. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to them in the Purchase Agreement (as defined below).

In addition to the foregoing, we have examined originals or copies, certified or otherwise identified to our satisfaction, of such instruments, corporate records, certificates of public officials, certificates from the transfer agent, certificates of officers of the Company and the Panamanian Guarantors, and other documents, and have made such investigations of law, as we have deemed necessary or advisable as a basis for the opinions set forth herein.

We have also reviewed the records of the Vessel at the Merchant Marine Administration of the Panama Maritime Authority and at the Public Registry of Titles and Encumbrances of Vessels (the “Public Registry of Vessels”). We have further examined such provisions of Panamanian laws and regulations as we have deemed relevant for purposes of this opinion.

For purposes of this opinion, the Purchase Agreement, the Indenture, the Intercreditor Agreement, the Securities and the Security Agreement will be referred to herein together as the “Transaction Documents”.

In our examination, we have assumed, with your permission: (i) the genuineness of all signatures, (ii) the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies, (iii) the due organization, existence and good standing of all parties to the Transaction Documents and the Panamanian Mortgages, other than the Company and the Panamanian Guarantors, (iv) the capacity, power and authority of all parties to execute all documents and agreements submitted to us, other than the Company and the Panamanian Guarantors, (v) the due authorization, execution and delivery of all documents and agreements submitted to us by all parties thereto, other than the Company and the Panamanian Guarantors, (vi) that the Transaction Documents (other than the Panamanian Mortgages) are a legal, valid and binding obligation, enforceable against the parties thereto (other than the Company and the Panamanian Guarantors) in accordance with their respective terms under, and comply in all material respects with, the laws governing the Transaction Documents (other than the Panamanian Mortgages), (vii) that the proceeds of the Securities will not be used by the Company in Panama, (viii) that neither the Company nor the Panamanian Guarantors carry on any business activities that generate taxable income in Panama; and (ix) that the records at the Public Registry of Vessels of the Panama Maritime Authority and the Directorate General of the Merchant Marine of the Republic of Panama with respect to the Vessels are accurate, complete and up to date.

As to all questions of fact material to this opinion, we have relied, without independent investigation, upon certificates or comparable documents of officers and representatives of the Company and upon the representations and warranties contained in the Purchase Agreement.

Based upon the foregoing and subject to the qualifications set forth herein below, we are of opinion that:

a) With regard to the opinion set forth in paragraphs 3 and 13 above, the term enforceable means that the obligations assumed by the party against whom enforcement is sought are of a type which the courts of Panama will enforce. It does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In

particular, enforcement may be limited by applicable bankruptcy, insolvency, fraudulent transfer, banking intervention, reorganization, forceful liquidation, moratorium and other similar laws affecting creditors` rights generally, or by concepts of materiality, reasonableness, good faith and fair dealings, and claims may become barred under applicable statutes of limitation or may be or become subject to defenses of set-off, counterclaim or other similar defenses.

b) With regard to the opinion set forth in paragraph 5 above, the courts of Panama will not apply or give effect to any provision of foreign law that violates the public policy of Panama.

c) With regard to the opinions set forth in paragraphs 6, 11 and 17 above, before any Transaction Document is used before any court or governmental authority in Panama (i) the signatures of the parties who executed such Transaction Document outside of Panama must be authenticated by a diplomatic or consular officer of Panama or by an Apostille pursuant to the 1961 Hague Convention Abolishing the Requirement of Legalization of Foreign Public Documents, (ii) such Transaction Document must be translated into Spanish by a licensed translator in Panama and (iii) stamp taxes at the rate of $0.10 per each $100 of face value or fraction thereof will become due and payable. In the case of the Panamanian Mortgages, the amounts paid in Notarial Paper for their protocolization and in registration duties would be deducted from the applicable stamp tax.

d) With regard to the opinion set forth in paragraph 19 above, we have limited our search to a review, as diligent as circumstances have permitted, of the dockets or records of the civil courts of the First Judicial Circuit of Panama in respect of actions filed against the Company within the past twelve months seeking an award for monetary damages in excess of US$1,000,000. A search of said dockets and court records cannot guarantee, however, that an action against the Company does not exist in said courts or before any other governmental authority in Panama.

We are licensed to practice law in Panama and we do not purport to be experts on, or to express any opinion herein concerning, any laws other than the laws of Panama as in effect on the date hereof.

This opinion is addressed to you and is solely for your benefit and the benefit of your successors, permitted assigns and legal counsel and only in connection with the transactions contemplated by the Transaction Documents. Except as may be required or requested pursuant to law or regulation, this opinion may not be relied upon by you for any other purpose or furnished to, circulated, quoted, filed with or relied upon by any other person, firm, corporation or other entity for any purpose without our prior written consent.

This opinion is being furnished to you pursuant to Section 5(d) of the Purchase Agreement dated April 10, 2014 (the “Purchase Agreement”) among McDermott International, Inc., a Panamanian corporation (the “Company”), the guarantors listed in Schedule A thereto (the “Guarantors”), and you, as representative of the several initial purchasers listed therein (the “Initial Purchasers”), relating to the issuance and sale by the Company to the Initial Purchasers, severally, of $500 million aggregate principal amount of the Company’s 8.000% Senior Secured Notes due 2021 (the “Notes”). The Notes are to be issued under an Indenture, dated as of April 16, 2014 (the “Indenture”), among the Company, the Guarantors and Wells Fargo Bank, National Association, as trustee and collateral agent (the “Trustee”), and guaranteed by the Guarantors to the extent set forth in the Indenture (the “Guarantees” and, together with the Notes, the “Securities”). Capitalized terms used but not defined herein shall have the respective meanings ascribed to such terms in the Purchase Agreement.

In connection with the sale of the Securities, the Company has prepared a Preliminary Offering Circular, dated April 4, 2014 (the “Preliminary Offering Circular”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated April 10, 2014 (the “Pricing Supplement”), describing the terms of the Securities, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase the Securities. The Preliminary Offering Circular and the Pricing Supplement are collectively referred to as the “Pricing Disclosure Package.” For purposes of this letter, “Time of Sale” means [ ] p.m. (Eastern time) on April 10, 2014.

The documents described in clauses 1, 2, 5, 6, 7, 8 and 9 above are hereinafter referred to as “Opinion Documents”.

In giving the opinions set forth below, we have relied, without independent investigation or verification, to the extent we deemed appropriate, on the certificates, statements or other representations of officers or other representatives of the Company and the Guarantors and of governmental and public officials, with respect to the accuracy of the factual matters contained in or covered by such certificates, statements or representations. In making our examination, we have assumed the legal capacity of all natural persons, that all signatures on documents examined by us are genuine, all documents submitted to us as originals are authentic and complete and all documents submitted to us as copies are true and correct copies of the originals of such documents.

In rendering the opinions expressed below, we have also assumed with your permission and without independent verification or inquiry:

On the basis of and subject to the limitations, exceptions, qualifications and assumptions set forth herein, we are of the opinion that:

(b) Each Texas Financing Statement is in appropriate form for filing in the Texas Filing Office. Upon the filing of the Texas Financing Statements in the Texas Filing Office, the Trustee will have a perfected security interest in that portion of the Subject Collateral in which a security interest can be perfected by the filing of a financing statement under the Uniform Commercial Code as in effect on the date hereof in the State of Texas (the “Texas UCC”).

We have reviewed the Pricing Disclosure Package and the Offering Circular and have participated in conferences with officers and other representatives of the Company and the Guarantors, with representatives of the Company’s independent registered public accounting firm and with your representatives and your counsel, at which the contents of the Pricing Disclosure Package, the Offering Circular and related matters were discussed. The purpose of

our professional engagement was not to establish or confirm factual matters set forth in the Pricing Disclosure Package or the Offering Circular, and we have not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Pricing Disclosure Package and the Offering Circular involve matters of a non-legal nature. Accordingly, we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in, the Pricing Disclosure Package and the Offering Circular (except to the extent stated in paragraph 11 above). Subject to the foregoing and on the basis of the information we gained in the course of performing the services referred to above, we advise you that nothing came to our attention that caused us to believe that:

(a) the Pricing Disclosure Package, as of the Time of Sale, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

(b) the Offering Circular, as of its date or as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that in each case we have not been asked to, and do not, express any belief with respect to (1) the financial statements and schedules or other financial, accounting or statistical information or data or the report on the effectiveness of internal control over financial reporting contained or included or incorporated by reference therein or omitted therefrom or (2) the representations and warranties and other statements of fact contained in the exhibits to the documents incorporated by reference therein.

(a) Our opinions in paragraphs 1 through 8 are subject to the effect of (i) applicable bankruptcy, insolvency, reorganization, arrangement, fraudulent transfer or conveyance, moratorium, conservatorship and similar laws affecting creditors’ rights and remedies generally, (ii) general principles of equity (whether considered in a proceeding in equity or at law), including, without limitation, the possible unavailability of specific performance, injunctive relief or any other equitable remedy and (iii) principles of materiality and reasonableness and implied covenants of good faith and fair dealing.

(b) Certain of the remedial, waiver, consent and other provisions of the Security Documents may be further limited or rendered unenforceable under existing laws or judicial decisions. However, subject to the other express qualifications contained herein, such laws or judicial decisions do not, in our opinion, substantially interfere with the practical realization of the principal benefits expressed in the Security Documents, except for the economic consequences of any procedural delay that might result from such laws or decisions.

(c) We express no opinion as to the enforceability of any provision in any of the Opinion Documents, to the extent relating to: (i) any failure to comply with requirements concerning notices, relating to delay or omission to enforce rights or remedies or purporting to waive or affect rights, claims, defenses or other benefits to the extent that any of the same cannot be waived or so affected under applicable law; (ii) indemnities or exculpation from liability to the extent prohibited by federal or state laws and the public policies underlying those laws or that might require indemnification for, or exculpation from liability on account of, negligence, willful misconduct, unlawful acts, violations of securities laws, fraud or illegality of an indemnified or exculpated party; (iii) the disregard of any course of dealing between the parties; (iv) an attempt to grant to any party conclusive rights of determination; (v) an attempt to confer subject matter jurisdiction or venue on any federal court of the United States; (vi) methods or procedures for service of process; (vii) the establishment of evidentiary standards; (viii) the severability of unenforceable provisions from the Intercreditor Agreement or the Security Documents to the extent that the enforcement of remaining provisions would frustrate the fundamental intent of the parties; (ix) the preservation of the solvency of any guarantor, pledgor or grantor by purporting to limit (by formula or otherwise) the amount of the liability of, or to provide rights of contribution or subrogation in favor of, such guarantor, pledgor or grantor; (x) any guaranty provided by, or any joint and several liability imposed upon, or the grant of a Lien by, any person or entity that is not an “eligible contract participant” within the meaning of Section 1a(18) of the Commodity Exchange Act, insofar as such guaranty or such joint and several liability covers, or such Lien secures, an agreement, contract or transaction that constitutes a “swap” within the meaning of Section 1a(47) of the Commodity Exchange Act; (xi) the grant of any right of set-off to the extent that such right can be exercised without notice or with respect to any contingent or unmatured obligation or with respect to a trust account or other deposit account, or by or against any Person that is not a party to the Transaction Documents; and (xii) a waiver of any objection based on inappropriate venue or forum non conveniens of any federal court.

(d) We express no opinion as to the effect of any state or federal securities laws, rules or regulations insofar as they are applicable to, or otherwise affect any party to (in its capacity as a party to), the Intercreditor Agreement or the Security Documents, the transactions contemplated by the Intercreditor Agreement or the Security Documents or the exercise of any rights or remedies of any party to the Intercreditor Agreement or the Security Documents, other than the Investment Company Act of 1940, as amended, to the extent specifically covered by our opinion in paragraph 13 above.

(e) We express no opinion as to the effect on the opinions expressed herein of (i) the compliance or non-compliance of the Trustee or any of the holders of the Notes with any state, federal or other laws, rules or regulations applicable to it, (ii) the legal or regulatory status or the nature of the business of any of the Trustee or any of the holders of the Notes, (iii) other facts specifically pertaining to the Trustee or any of the holders of the Notes or (iv) any state, federal or other laws, rules or regulations or orders that may be applicable as a result of the involvement of the Trustee or any of the holders of the Notes in the transactions contemplated by the Intercreditor Agreement or any of the Security Documents or because of the legal or regulatory status or the nature of the business of the Trustee or any of the holders of the Notes.

(f) We call to your attention that Section 552 of the Bankruptcy Code (11 U.S.C. § 101 et seq.) limits the extent to which proceeds realized and property acquired by a debtor after the commencement of a case under such Bankruptcy Code may be subject to a security interest arising from a security agreement entered into by the debtor before the commencement of that case.

(g) Our opinions in paragraphs 5 and 6 hereof are subject to the following assumptions, qualifications and limitations:

(i) We express no opinion as to any property or transaction that is excluded from the scope of Article 9 of the New York UCC or the Delaware UCC by Section 9-109 thereof or from the scope of Chapter 9 of the Texas UCC by Section 9.109 thereof or as to the perfection of any security interest by a means other than those described in paragraph 6 hereof.

(ii) We express no opinion as to the creation of a security interest in any collateral to the extent that the description of such collateral does not reasonably identify the property purported to be described thereby in accordance with Section 9-108 of the New York UCC.

(iii) In the case of proceeds (within the meaning of Section 9-102 of the New York UCC, Section 9-102 of the Delaware UCC and Section 9.102 of the Texas UCC), including that portion of the collateral under the Security Documents that constitutes proceeds, continuation of perfection is limited to the extent set forth in Section 9-315 of the New York UCC, Section 9-315 of the Delaware UCC and Section 9.315 of the Texas UCC.

(iv) We express no opinion with respect to any actions that may be required to be taken periodically under the New York UCC, the Delaware UCC or the Texas UCC in order for the effectiveness of the Financing Statements or perfection of any security interest to be maintained.

(h) We express no opinion as to (i) the creation of any lien or security interest under the Security Documents, except as expressly set forth in paragraph 5 or 8 above, (ii) the priority of the liens and security interests created by the Security Documents with respect to any collateral thereunder, (iii) the filing or recording of the Security Documents, the Financing Statements or any other instruments relating thereto, except as set forth in paragraphs 6, 7 and 8 above, (iv) the accuracy of the descriptions of any collateral contained in the Security Documents or the Financing Statements, or (v) the creation or perfection of a security interest in any collateral consisting of commercial tort claims, consumer goods, cooperative interests, farm products, fixtures, timber to be cut, and minerals and the like (including as-extracted collateral). We have assumed, with your approval and without independent verification, that the Financing Statements set forth the correct name and address of the Trustee. We undertake no obligation to file the Financing Statements or the U.S. Vessel Mortgages.

(i) We call to your attention that the perfection, effect of perfection and non-perfection, and the priority, of the security interests created under the Security Documents may be governed by laws other than the laws of the State of New York, the State of Delaware or the State of Texas. In this regard, among other things, we call to your attention Section 9-311 of the New York UCC, Section 9-311 of the Delaware UCC and Section 9.311 of the Texas UCC relating to the perfection of security interests in property subject to certain statutes, regulations and treaties.

(j) We call to your attention that the exercise of any remedies against the Intermac 600 and DB 16 will be subject to the requirements and limitations of the Ship Mortgage Act.

(k) We express no opinion as to the specific remedy a court may grant or impose with respect to the provisions in the U.S. Vessel Mortgages requiring the mortgagor to perform specific affirmative acts, or the process, jurisdiction or venue of any particular court in respect to any action by any party under the U.S. Vessel Mortgages.

(l) We express no opinion as to whether the Intermac 600 or the DB 16 is free of any claims which might affect the priority of any U.S. Vessel Mortgage or, except as set forth in paragraphs 7 and 8 above, to the documentation, title, papers, registry, books and accounts, or operations, of the Intermac 600 or the DB 16.

(m) The opinions contained in paragraphs 7 and 8 above are based solely on a review of copies of an abstract of title, a Certificate of Documentation and a Certificate of Ownership issued by the United States Coast Guard and are subject to the additional assumptions that there are no material inaccuracies in such certificates that would cause a rescission of the documentation of the Intermac 600 or the DB 16.

(n) In the event of a foreclosure of any U.S. Vessel Mortgage, in order to operate the Intermac 600 or the DB 16 in its present capacity, the buyer of the Intermac 600 or the DB 16, as applicable, must be a citizen of the United States within the meaning of Title 46, Section 802, of the United States Code, entitled to own and document the Intermac 600 or the DB 16, as applicable, under the laws of the United States of America and to operate the Intermac 600 or the DB 16, as applicable, in the then applicable trade.

The opinions set forth above are limited in all respects to matters of applicable U.S. federal law, the laws of the State of Texas, the contract laws of the State of New York, the Delaware U.C.C. and the Delaware General Corporation Law, as in effect on the date hereof, and we have assumed that no laws, rules or regulations, and no judicial, administrative or other action of any other jurisdiction would adversely affect the opinions set forth herein.

This opinion letter is being furnished to you solely for your use in your capacity as Initial Purchasers in connection with the issuance and sale of the Securities, and no other use or distribution of this opinion letter may be made without our prior written consent. This opinion letter speaks as of the date hereof, and we disclaim any obligation to update this opinion letter.

I am the Senior Vice President, General Counsel and Corporate Secretary of McDermott International, Inc., a Panamanian corporation (the “Company”). This opinion is being furnished to you pursuant to Section 5(e) of the Purchase Agreement dated April 10, 2014 (the “Purchase Agreement”) among McDermott International, Inc., a Panamanian corporation (the “Company”), the guarantors listed in Schedule A thereto (the “Guarantors”) and you, as representative of the several initial purchasers listed therein (the “Initial Purchasers”), relating to the issuance and sale by the Company to the Initial Purchasers, severally, of $500 million aggregate principal amount of the Company’s 8.000% Senior Secured Notes due 2021 (the “Notes”). Payment of principal of, premium, if any, and interest on the Notes will be guaranteed by the Guarantors to the extent set forth in the Indenture (as defined below) (the “Guarantees” and, together with the Notes, the “Securities”). The Securities will be issued pursuant to an indenture, dated as of the date hereof (the “Indenture”), among the Company, the Guarantors and Wells Fargo Bank, National Association, as trustee (the “Trustee”). Capitalized terms used but not defined herein that are defined in the Purchase Agreement shall have the respective meanings assigned to them in the Purchase Agreement.

In connection with the sale of the Securities, the Company has prepared a Preliminary Offering Circular, dated April 4, 2014 (the “Preliminary Offering Circular”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement, dated April 10, 2014 (the “Pricing Supplement”), describing the terms of the Securities, each for use by such Initial Purchaser in connection with its solicitation of offers to purchase the Securities.

In making my examination, I have assumed the legal capacity of all natural persons, that all signatures on documents examined by me are genuine, all documents submitted to me as originals are authentic and complete and all documents submitted to me as copies are true and correct copies of the originals of such documents.

On the basis of and subject to the limitations, exceptions, qualifications and assumptions set forth herein, I am of the opinion that:

I have reviewed the Pricing Disclosure Package and the Offering Circular and have participated in conferences with officers and other representatives of the Company, your representatives, your counsel and representatives of the independent registered public accounting firm of the Company at which the contents of the Pricing Disclosure Package, the Offering Circular and related matters were discussed. Many of the determinations required to be made in the preparation of the Pricing Disclosure Package and the Offering Circular involve matters of a non-legal nature. Accordingly, I did not independently verify such information and am not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Pricing Disclosure Package and the Offering Circular (except to the extent set forth in paragraph 4 above). Subject to the foregoing, I advise you that no facts have come to my attention which lead me to believe that:

it being understood that in each case I do not express any belief with respect to (1) the financial statements and schedules or other financial, accounting or statistical information or data or the report on the effectiveness of internal control over financial reporting contained or included or incorporated by reference therein or omitted therefrom or (2) the representations and warranties and other statements of fact contained in the exhibits to the documents incorporated by reference therein.

In rendering the opinion expressed in the first sentence of paragraph 1 above, I have relied solely upon certificates from the Secretary of State of the State of Delaware.

I express no opinion as to the effect of any state or federal securities laws, rules or regulations in paragraph 6 above.

I am a member of the bar of the State of Louisiana and, except as otherwise expressly stated herein, the opinions expressed herein are limited to matters governed by the laws of the State of Louisiana and the General Corporation Law of the State of Delaware, in each case, as in effect on the date hereof, and I have assumed that no laws, rules or regulations, and no judicial, administrative or other action of any other jurisdiction would adversely affect the opinions set forth herein.

Phrases such as “to my knowledge,” “known to me” and those with equivalent words refer to my conscious awareness of information, without any independent investigation.

This opinion is given as of the date hereof and I assume no obligation to update or supplement this opinion to reflect any facts or circumstances which may hereafter come to my attention or any changes in laws which may hereafter occur. This opinion is rendered solely to you in connection with the above matter. This opinion may not be relied upon by you for any other purpose or relied upon by or furnished to any other person without my prior written consent.
