Morgan Stanley & Co. Incorporated
1585 Broadway
New York, New York 10036

Dear Sirs and Mesdames:

         J. Ray McDermott, S.A., a Panamanian corporation (the "COMPANY"),
proposes to issue and sell to Morgan Stanley & Co. Incorporated (the "INITIAL
PURCHASER") $200,000,000 principal amount of its 11% Senior Secured Notes due
2013 (the "SECURITIES") to be issued pursuant to the provisions of an Indenture
to be dated December 8, 2003 (the "INDENTURE") among the Company, each of the
subsidiaries of the Company named in Schedule A hereto (collectively the
"GUARANTORS") and The Bank of New York, as Trustee (the "TRUSTEE"). The
Securities will be guaranteed (the "INITIAL GUARANTEES") by each Guarantor. The
Company's obligations under the Indenture and the Securities will be secured by
a first priority lien (the "COLLATERAL") on (i) all of the capital stock of
certain Material Subsidiaries (as hereinafter defined) owned directly by the
Company or a Guarantor and (ii) certain marine construction vessels owned by the
Company and its subsidiaries pursuant to a pledge agreement (the "PLEDGE
AGREEMENT"), fleet mortgages and ship mortgages (the "MORTGAGES" and, together
with the Pledge Agreement, the "SECURITY DOCUMENTS").

         The Securities will be offered without being registered under the
Securities Act of 1933, as amended (the "SECURITIES ACT"), to qualified
institutional buyers in compliance with the exemption from registration provided
by Rule 144A under the Securities Act and in offshore transactions in reliance
on Regulation S under the Securities Act ("REGULATION S").

         The Initial Purchaser and its direct and indirect transferees will be
entitled to the benefits of a Registration Rights Agreement to be dated the
Closing Date among the Company, the Guarantors and the Initial Purchaser (the
"REGISTRATION RIGHTS Agreement"), pursuant to which the Company will agree to
file, within the time periods specified therein, (i) a registration statement
under the Securities Act relating to the Company's 11% Senior Secured Notes due
2013 in a like aggregate principal amount as the Company issued under the
Indenture, identical in all material respects to the Securities and registered
under the Securities Act (the "EXCHANGE SECURITIES"), to be offered in exchange
for the Securities (such offer to exchange being referred to as the "EXCHANGE
Offer") and the guarantees thereof by each of the Guarantors (the "EXCHANGE
GUARANTEES" and, together with the Initial Guarantees, the "GUARANTEES") or (ii)
a shelf registration statement pursuant to Rule 415 under the Securities Act
relating to the resale by certain holders of the Offered Securities and to use
its commercially reasonable



efforts to cause such registration statements to be declared and remain
effective and usable for the periods specified in the Registration Rights
Agreement and to consummate the Exchange Offer.

         In connection with the sale of the Securities, the Company has prepared
a preliminary offering memorandum (together with the Offering Memorandum
Supplement dated as of November 21, 2003, the "PRELIMINARY MEMORANDUM") and will
prepare a final offering memorandum (the "FINAL MEMORANDUM" and, with the
Preliminary Memorandum, each a "MEMORANDUM") including a description of the
terms of the Securities, the terms of the offering and a description of the
Company.

         1.       Representations and Warranties. The Company represents and
warrants to, and agrees with, you that:

                  (a)      the Preliminary Memorandum does not contain and the
         Final Memorandum, in the form used by the Initial Purchaser to confirm
         sales and on the Closing Date (as defined in Section 4), will not
         contain any untrue statement of a material fact or omit to state a
         material fact necessary to make the statements therein, in the light of
         the circumstances under which they were made, not misleading, except
         that the representations and warranties set forth in this paragraph do
         not apply to statements or omissions in either Memorandum based upon
         information relating to the Initial Purchaser furnished to the Company
         in writing by the Initial Purchaser expressly for use therein.

                  (b)      The Company has been duly incorporated, is validly
         existing as a corporation in good standing under the laws of the
         Republic of Panama, has the corporate power and authority to own its
         property and to conduct its business as described in each Memorandum
         and is duly qualified to transact business and is in good standing in
         each jurisdiction in which the conduct of its business or its ownership
         or leasing of property requires such qualification, except to the
         extent that the failure to be so qualified or be in good standing would
         not have a material adverse effect on the business, condition
         (financial or otherwise), earnings or results of operations of the
         Company and its subsidiaries, taken as a whole (a "MATERIAL ADVERSE
         EFFECT").

                  (c)      Each Material Subsidiary (as defined below) of the
         Company has been duly incorporated, is validly existing and in good
         standing under the laws of the jurisdiction of its organization, has
         the corporate or other organizational power and authority to own its
         property and to conduct its business as described in each Memorandum
         and is duly qualified to transact business and is in good standing in
         each jurisdiction in which the conduct of its business or its ownership
         or leasing of property requires such qualification, except to the
         extent that the failure to be so qualified or be in good standing would
         not have a Material Adverse

                                       2



         Effect. Except as described in the Final Memorandum, all of the issued
         and outstanding capital stock or ownership interests of each Material
         Subsidiary has been duly authorized and validly issued, is fully paid
         and non-assessable and is owned by the Company, directly or through
         subsidiaries, free and clear of any security interest, lien, option,
         claim or other encumbrance. For purposes of this Agreement, a "MATERIAL
         SUBSIDIARY" is (i) the owner of one or more of the major marine
         construction vessels described in each Memorandum as collateral for the
         obligations under the Securities and the Exchange Securities or (ii) a
         subsidiary of the Company that constitutes a "significant subsidiary"
         of the Company within the meaning of Rule 1-02(w) of Regulation S-X of
         the 1933 Act and the 1934 Act.

                  (d)      This Agreement has been duly authorized, executed and
         delivered by the Company and each Guarantor.

                  (e)      The Securities have been duly authorized and, when
         executed and authenticated in accordance with the provisions of the
         Indenture and delivered to and paid for by the Initial Purchaser in
         accordance with the terms of this Agreement, will be valid and binding
         obligations of the Company, enforceable in accordance with their terms,
         subject to applicable bankruptcy, insolvency, reorganization,
         fraudulent conveyance or transfer, moratorium or similar laws relating
         to or affecting creditors' rights generally and general principles of
         equity (whether considered in a proceeding at law or in equity), and
         will be entitled to the benefits of the Indenture and the Registration
         Rights Agreement pursuant to which such Securities are to be issued.

                  (f)      The Initial Guarantee of each Guarantor has been duly
         authorized by such Guarantor; and on the Closing Date, will have been
         duly executed and delivered by each such Guarantor. When the Offered
         Securities have been issued, executed and authenticated in accordance
         with the provisions of the Indenture and delivered to and paid for by
         the Purchaser in accordance with the terms of this Agreement, the
         Initial Guarantee of each Guarantor will constitute valid and legally
         binding obligations of such Guarantor, enforceable in accordance with
         their terms, subject to bankruptcy, insolvency, reorganization,
         fraudulent conveyance or transfer, moratorium or similar laws relating
         to or affecting creditors' rights generally and general principles of
         equity (whether considered in a proceeding at law or in equity).

                  (g)      On the Closing Date, the Exchange Securities will
         have been duly authorized by the Company. When the Exchange Securities
         are issued, executed and authenticated in accordance with the terms of
         the Exchange Offer and the Indenture, the Exchange Securities will be
         entitled to the benefits of the Indenture and will be the valid and
         binding obligations of the Company, enforceable against the Company in

                                       3



         accordance with their terms, subject to applicable bankruptcy,
         insolvency, reorganization, fraudulent conveyance or transfer,
         moratorium or similar laws relating to or affecting creditors' rights
         generally and general principles of equity (whether considered in a
         proceeding at law or in equity).

                  (h)      The Exchange Guarantee by each Guarantor has been
         duly authorized by such Guarantor; and, when issued, will have been
         duly executed and delivered by such Guarantor. When the Exchange
         Securities have been issued, executed and authenticated in accordance
         with the terms of the Exchange Offer and the Indenture, and when the
         Exchange Guarantees have been issued in accordance with the terms of
         the Exchange Offer and Indenture, the Exchange Guarantee of each
         Guarantor will constitute valid and legally binding obligations of such
         Guarantor, enforceable in accordance with its terms, subject to
         applicable bankruptcy, insolvency, reorganization, fraudulent
         conveyance or transfer, moratorium or similar laws relating to or
         affecting creditors' rights generally and general principles of equity
         (whether considered in a proceeding at law or in equity).

                  (i)      Each of the Indenture and the Registration Rights
         Agreement has been duly authorized, executed and delivered by, and is a
         valid and binding agreement of, the Company and each Guarantor,
         enforceable in accordance with its terms, subject to applicable
         bankruptcy, insolvency, reorganization, fraudulent conveyance or
         transfer, moratorium or similar laws relating to or affecting
         creditors' rights generally and general principles of equity (whether
         considered in a proceeding at law or in equity) and except as rights to
         indemnification and contribution under the Registration Rights
         Agreement may be limited under applicable law;

                  (j)      Each of the Security Documents has been duly
         authorized by the Company and each Guarantor, and when executed and
         delivered by the Company and each Guarantor will be a valid and binding
         agreement of the Company and each Guarantor party thereto, as
         applicable, enforceable in accordance with its terms, subject to
         applicable bankruptcy, insolvency, reorganization, fraudulent
         conveyance or transfer, moratorium or similar laws relating to or
         affecting creditors' rights generally and general principles of equity
         (whether considered in a proceeding at law or in equity); the Security
         Documents, when duly executed and delivered, will create valid and
         (when all required filings and recordings with respect to, and
         deliveries of, Collateral have been made as described in the Security
         Documents) perfected security interests or mortgage liens in the
         Collateral; each of the representations and warranties made by the
         Company and each Guarantor in each Security Document to which it is a
         party is true and correct in all material respects as of the Closing
         Date, except to the extent that such representations and warranties
         expressly

                                       4



         relate to an earlier date (in which case such representations and
         warranties shall be true and correct in all material respects as of
         such earlier date).

                  (k)      None of the Company or any of the Material
         Subsidiaries is (i) in violation of its organizational documents, (ii)
         in default in the performance or observance of any obligation,
         agreement, covenant or condition contained in any contract, indenture,
         mortgage, loan agreement, note, lease or other instrument to which the
         Company or any of the Material Subsidiaries is a party or by which it
         or any of them may be bound, or to which any of their property or
         assets is subject, except in the case of clause (ii) above for any such
         defaults as are disclosed in the Final Memorandum and any such defaults
         that would not, in the aggregate, have a Material Adverse Effect, or
         (iii) in violation of any applicable law, rule or regulation, or any
         judgment, order or decree of any court with jurisdiction over the
         Company or any subsidiary of the Company, or other governmental or
         regulatory authority with jurisdiction over the Company, any of its
         subsidiaries, except for any such violations as are disclosed in the
         Final Memorandum and any such violations that would not, in the
         aggregate, have a Material Adverse Effect.

                  (l)      No labor dispute with the employees of the Company or
         any of the Material Subsidiaries exists or, to the knowledge of the
         Company, is imminent, except for any such disputes that would not, in
         the aggregate, have a Material Adverse Effect; and the Company is not
         aware of any existing or imminent labor disturbance by the employees of
         any of its principal suppliers, manufacturers or contractors which
         would be expected to result in a Material Adverse Effect;

                  (m)      The Company and the Material Subsidiaries own or
         possess, or can acquire on reasonable terms, the material patents,
         patent rights, licenses, inventions, copyrights, know-how (including
         trade secrets and other unpatented and/or unpatentable proprietary or
         confidential information, systems or procedures), trademarks, service
         marks and trade names (collectively, "patent and proprietary rights")
         presently employed by them in connection with the respective businesses
         now operated by them, and none of the Company or any of the Material
         Subsidiaries has received any notice or is otherwise aware of any
         infringement of or conflict with asserted rights of others with respect
         to any patent or proprietary rights, or of any facts which would render
         any patent and proprietary rights invalid or inadequate to protect the
         interest of the Company or any of the Material Subsidiaries and which
         infringement or conflict (if the subject of any unfavorable decision,
         ruling or finding) or invalidity or inadequacy would result in a
         Material Adverse Effect).

                  (n)      The Company and the Material Subsidiaries possess
         such certificates, authorizations or permits issued by the appropriate
         state, federal or foreign regulatory agencies or bodies necessary to

                                       5



         respective businesses now operated by them, except for such
         certificates, authorizations or permits of which the failure by the
         Company to possess would not have a Material Adverse Effect, and none
         of the Company or any of the Material Subsidiaries has received any
         notice of proceedings relating to the revocation or modification of any
         such certificate, authority or permit which, if the subject of an
         unfavorable decision, ruling or finding, would have a Material Adverse
         Effect.

                  (o)      The execution and delivery by the Company and each
         Guarantor of, and the performance by the Company of its obligations
         under, this Agreement, the Indenture, the Registration Rights
         Agreement, the Security Documents, the Securities and the Exchange
         Securities will not contravene any provision of applicable law or the
         articles of incorporation or by-laws of the Company or any indenture,
         mortgage, loan agreement, note, lease or other instrument binding upon
         the Company or any of its subsidiaries that is material to the Company
         and its subsidiaries, taken as a whole, or any judgment, order or
         decree of any governmental body, agency or court having jurisdiction
         over the Company or any subsidiary, and no consent, approval,

         Rights Agreement, required by the securities or Blue Sky laws of the
         various states in connection with the offer and sale of the Securities,
         or required by Federal and state securities laws with respect to the
         Company's obligations under the Registration Rights Agreement.

                  (p)      There has not occurred any material adverse change,
         or any development involving a prospective material adverse change, in
         the condition, financial or otherwise, or in the earnings, business or
         operations of the Company and its subsidiaries, taken as a whole, from
         that set forth in the Final Memorandum.

                  (q)      Except as set forth in the Final Memorandum, there
         are no legal or governmental proceedings pending or threatened to which
         the Company or any of its subsidiaries is a party or to which any of
         the properties of the Company or any of its subsidiaries is subject
         other than proceedings accurately described in all material respects in
         each Memorandum and proceedings that would not have a Material Adverse
         Effect or have a material adverse effect on the power or ability of the
         Company to perform its obligations under this Agreement, the Indenture,
         the Registration Rights Agreement, the Security Documents or the
         Securities or to consummate the transactions contemplated by the Final
         Memorandum.

                                       6



                  (r)      Except as described in the Final Memorandum, the
         Company and its subsidiaries (i) are in compliance with all applicable
         foreign, federal, state and local laws and regulations relating to the
         protection of human health and safety, the environment or hazardous or
         toxic substances or wastes, pollutants or contaminants ("ENVIRONMENTAL
         LAWS"), (ii) have received all permits, licenses or other approvals
         required of them under applicable Environmental Laws to conduct their
         respective businesses and (iii) are in compliance with all terms and
         conditions of any such permit, license or approval, except where such
         noncompliance with Environmental Laws, failure to receive required
         permits, licenses or other approvals or failure to comply with the
         terms and conditions of such permits, licenses or approvals would not,
         singly or in the aggregate, have a Material Adverse Effect on the
         Company and its subsidiaries, taken as a whole.

                  (s)      Except to the extent described in the Final
         Memorandum, there are no costs or liabilities associated with
         Environmental Laws (including, without limitation, any capital or
         operating expenditures required for clean-up, closure of properties or
         compliance with Environmental Laws or any permit, license or approval,
         any related constraints on operating activities and any potential
         liabilities to third parties) which would, singly or in the aggregate,
         have a Material Adverse Effect.

                  (t)      The Company and each of its subsidiaries has filed
         all foreign, federal or state income and franchise tax returns required
         to be filed after giving effect to any applicable extension in the time
         for filing (except insofar as the failure to file such returns would
         not, in the aggregate have a material adverse effect) and have paid all
         material taxes shown thereon as due; and all material tax liabilities
         of the Company and the Material Subsidiaries are adequately provided
         for on the books of the Company and the Material Subsidiaries.

                  (u)      Except as disclosed in each Memorandum, the Company
         and its subsidiaries are insured by recognized, and, to the Company's
         knowledge, financially sound institutions with policies in such amounts
         and with such deductibles and covering such risks as the Company
         generally deems adequate and customary for their businesses. The
         Company, in its reasonable judgment, has no reason to believe that it
         or any of its subsidiaries will not be able (i) to renew its existing
         insurance coverage as and when such policies expire or (ii) to obtain
         comparable coverage from similar institutions as may be necessary or
         appropriate to conduct its business as now conducted and at a cost that
         would not result in a Material Adverse Affect. Except as described in
         the Final Memorandum and except for such denials as would not result in
         a Material Adverse Effect, neither the Company nor any subsidiary has
         been denied any insurance coverage which it has sought or for which it
         has applied.

                                       7



                  (v)      The Company is not, and after giving effect to the
         offering and sale of the Securities and the application of the proceeds
         thereof as described in the Final Memorandum will not be, required to
         register as an "investment company" as such term is defined in the
         Investment Company Act of 1940, as amended.

                  (w)      Neither the Company nor any affiliate (as defined in
         Rule 501(b) of Regulation D under the Securities Act, an "AFFILIATE")
         of the Company has directly, or through any agent, (i) sold, offered
         for sale, solicited offers to buy or otherwise negotiated in respect
         of, any security (as defined in the Securities Act) which is or will be
         integrated with the sale of the Securities in a manner that would
         require the registration under the Securities Act of the Securities or
         (ii) offered, solicited offers to buy or sold the Securities by any
         form of general solicitation or general advertising (as those terms are
         used in Regulation D under the Securities Act) or in any manner
         involving a public offering within the meaning of Section 4(2) of the
         Securities Act.

                  (x)      None of the Company, its Affiliates or any person
         acting on its or their behalf has engaged or will engage in any
         directed selling efforts (within the meaning of Regulation S) with
         respect to the Securities and the Company and its Affiliates and any
         person acting on its or their behalf have complied and will comply with
         the offering restrictions requirement of Regulation S, except no
         representation, warranty or agreement is made by the Company in this
         paragraph with respect to the Initial Purchaser.

                  (y)      It is not necessary in connection with the offer,
         sale and delivery of the Securities to the Initial Purchaser in the
         manner contemplated by this Agreement to register the Securities under
         the Securities Act or to qualify the Indenture under the Trust
         Indenture Act of 1939, as amended.

                  (z)      The Securities satisfy the requirements set forth in
         Rule 144A(d)(3) under the Securities Act.

                  (aa)     The Company and its subsidiaries and to the knowledge

the period beginning on the date hereof and continuing to and including the date

Company that the Initial Purchaser will make an offering of the Securities

Final Memorandum, as soon as practicable after this Agreement is entered into as
in your judgment is advisable.

         4.       Payment and Delivery. Payment for the Securities shall be made
to the Company in Federal or other funds immediately available in New York City

designated in writing by you. The time and date of such payment are hereinafter
referred to as the "CLOSING DATE."

         The Securities shall be in definitive form or global form, as specified
by you, and registered in such names and in such denominations as you shall
request in writing not later than one full business day prior to the Closing
Date. The Securities shall be delivered to you on the Closing Date, with any

         5.       Conditions to the Initial Purchaser's Obligations. The
obligation of the Initial Purchaser to purchase and pay for the Securities on
the Closing Date is subject to the following conditions:

                  (a)      Subsequent to the execution and delivery of this
         Agreement and prior to the Closing Date:

                           (i)      there shall not have occurred any
                  downgrading, nor shall any notice have been given of any
                  intended or potential downgrading or of any review for a
                  possible change that does not indicate the direction of the
                  possible change, in the rating accorded the Company or any of
                  the Company's securities or in the rating outlook for the
                  Company by any "nationally recognized statistical rating
                  organization," as such term is defined for purposes of Rule
                  436(g)(2) under the Securities Act; and

                           (ii)     there shall not have occurred any change, or
                  any development involving a prospective change, in the
                  condition,

                                       9

                  amendments or supplements thereto subsequent to the date of
                  this Agreement) that, in your reasonable judgment, is material

                  impracticable to market the Securities on the terms and in the
                  manner contemplated in the Final Memorandum.

         with all of the agreements on its part to be performed hereunder on or
         before the Closing Date.

                  United States or to, or for the account or benefit of, U.S.
                  persons (i) as part of their distribution at any time or (ii)
                  otherwise until 40 days after the later of the commencement of
                  the offering and the closing date, except in either case in
                  accordance with Regulation S (or Rule 144A if available) under
                  the Securities Act. Terms used above have the meaning given to
                  them by Regulation S."

Terms used in this Section 7(b) have the meanings given to them by Regulation S.

         8.       Indemnity and Contribution. (a) The Company agrees to
indemnify and hold harmless the Initial Purchaser, each person, if any, who
controls the Initial Purchaser within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act, and each affiliate of the
Initial Purchaser within the meaning of Rule 405 under the Securities Act from
and against any and all losses, claims, damages and liabilities (including,
without limitation, any legal or other expenses reasonably incurred in
connection with defending or investigating any such action or claim) caused by
any untrue statement or alleged untrue statement of a material fact contained in
either Memorandum (as amended or supplemented if the Company shall have
furnished any amendments or supplements thereto), or caused by any omission or
alleged omission to state therein a material fact necessary to make the
statements therein in the light of the circumstances under which they were made
not misleading, except insofar as such losses, claims, damages or liabilities
are caused by any such untrue statement or omission or alleged untrue statement
or omission based upon information relating to the Initial Purchaser furnished
to the Company in writing by the Initial Purchaser through you expressly for use
therein; provided, however, that the foregoing indemnity agreement with respect
to any Preliminary Memorandum shall not inure to the benefit of the Initial
Purchaser from whom the person asserting any such losses, claims, damages or
liabilities purchased Securities, or

                                       16



any person controlling such Initial Purchaser, if a copy of the Memorandum (as
then amended or supplemented if the Company shall have furnished any amendments
or supplements thereto) was not sent or given by or on behalf of such Initial
Purchaser to such person at or prior to the written confirmation of the sale of
the Securities to such person, and if the Memorandum (as so amended or
supplemented) would have cured the defect giving rise to such losses, claims,
damages or liabilities, unless such failure is the result of noncompliance by
the Company with Section 6(a) hereof.

         (b)      The Initial Purchaser agrees to indemnify and hold harmless
the Company, its directors, its officers and each person, if any, who controls
the Company within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the foregoing indemnity
from the Company to the Initial Purchaser, but only with reference to
information relating to the Initial Purchaser furnished to the Company in
writing by the Initial Purchaser expressly for use in either Memorandum or any
amendments or supplements thereto.

         (c)      In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the
"INDEMNIFIED PARTY") shall promptly notify the person against whom such
indemnity may be sought (the "INDEMNIFYING PARTY") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in respect of the legal expenses of any indemnified party in
connection with any proceeding or related proceedings in the same jurisdiction,
be liable for the fees and expenses of more than one separate firm (in addition
to any local counsel) for all such indemnified parties and that all such fees
and expenses shall be reimbursed as they are incurred. Such firm shall be
designated in writing by Morgan Stanley & Co. Incorporated, in the case of
parties indemnified pursuant to Section 8(a), and by the Company, in the case of
parties indemnified pursuant to Section 8(b). The indemnifying party shall not
be liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party
from and against any loss or liability by reason of such

                                       17



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 fees and expenses of counsel as contemplated by the second
and third sentences of this paragraph, 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 30 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 prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

         (d)      To the extent the indemnification provided for in Section 8(a)
or 8(b) is unavailable to an indemnified party or insufficient in respect of any
losses, claims, damages or liabilities referred to therein, then each
indemnifying party under such paragraph, in lieu of indemnifying such
indemnified party thereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Initial Purchaser on
the other hand from the offering of the Securities or (ii) if the allocation
provided by clause 8(d)(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 8(d)(i) above but also the relative fault of the Company on the one
hand and of the Initial Purchaser on the other hand in connection with the
statements or omissions that resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The
relative benefits received by the Company on the one hand and the Initial
Purchaser on the other hand in connection with the offering of the Securities
shall be deemed to be in the same respective proportions as the net proceeds
from the offering of the Securities (before deducting expenses) received by the
Company and the total discounts and commissions received by the Initial
Purchaser bear to the aggregate offering price of the Securities. The relative
fault of the Company on the one hand and of the Initial Purchaser on the other
hand shall be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or by the Initial Purchaser and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.

         (e)      The Company and the Initial Purchaser agree that it would not
be just or equitable if contribution pursuant to this Section 8(d) were
determined by pro rata allocation or by any other method of allocation that does
not take account

                                       18



of the equitable considerations referred to in Section 8(d). The amount paid or
payable by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in Section 8(d) shall be deemed to include, subject to
the limitations set forth above, any out-of-pocket legal or other out-of-pocket
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 8, the Initial Purchaser shall not be required to
contribute any amount in excess of the amount by which the total price at which
the Securities resold by it in the initial placement of such Securities were
offered to investors exceeds the amount of any damages that the Initial
Purchaser has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The remedies provided for in this Section 8 are
not exclusive and shall not limit any rights or remedies which may otherwise be
available to any indemnified party at law or in equity.

         (f)      The indemnity and contribution provisions contained in this
Section 8 and the representations, warranties and other statements of the
Company contained in this Agreement shall remain operative and in full force and
effect regardless of (i) any termination of this Agreement, (ii) any
investigation made by or on behalf of the Initial Purchaser, any person
controlling the Initial Purchaser or any affiliate of the Initial Purchaser or
by or on behalf of the Company, its officers or directors or any person
controlling the Company and (iii) acceptance of and payment for any of the
Securities.

         9.       Termination. The Initial Purchaser may terminate this
Agreement by notice given by you to the Company, if after the execution and
delivery of this Agreement and prior to the Closing Date (i) trading generally
shall have been suspended or materially limited on, or by, the New York Stock
Exchange, the Nasdaq National Market, (ii) trading of any securities of
McDermott International, Inc. shall have been suspended on any exchange or in
any over-the-counter market, (iii) a material disruption in securities
settlement, payment or clearance services in the United States shall have
occurred, (iv) any moratorium on commercial banking activities shall have been
declared by Federal or New York State authorities or (v) there shall have
occurred any outbreak or escalation of hostilities, or any change in financial
markets, currency exchange rates or controls or any calamity or crisis that, in
your judgment, is material and adverse and which, singly or together with any
other event specified in this clause (v), makes it, in your judgment,
impracticable or inadvisable to proceed with the offer, sale or delivery of the
Securities on the terms and in the manner contemplated in the Final Memorandum.

         10.      Effectiveness. This Agreement shall become effective upon the
execution and delivery hereof by the parties hereto.

                                       19



         If this Agreement shall be terminated by the Initial Purchaser because
of any failure or refusal on the part of the Company to comply with the terms or
to fulfill any of the conditions of this Agreement the Company will reimburse
the Initial Purchaser for all out-of-pocket expenses (including the fees and
disbursements of its counsel) reasonably incurred by the Initial Purchaser in
connection with this Agreement or the offering contemplated hereunder.

         11.      Counterparts. This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         12.      Applicable Law. This Agreement shall be governed by and
construed in accordance with the internal laws of the State of New York.

         13.      Headings. The headings of the sections of this Agreement have
been inserted for convenience of reference only and shall not be deemed a part
of this Agreement.

   * a "Material Subsidiary"



                                                                       EXHIBIT A

                   OPINION OF OUTSIDE COUNSEL FOR THE COMPANY

         The opinion of the counsel for the Company, to be delivered pursuant to
Section 5(c) of the Purchase Agreement shall be to the effect that:

         A.       Each of the Purchase Agreement, the Indenture and the
Registration Rights Agreement has been duly authorized, executed and delivered
by each of J. Ray McDermott Engineering Holdings, Inc., a Delaware corporation
("JRMEHI"), J. Ray McDermott Holdings, Inc., a Delaware corporation ("JRMHI"),
J. Ray McDermott, Inc., a Delaware corporation ("JRMI"), Mentor Subsea
Technology Services, Inc., a Delaware corporation ("MENTOR") and OPI Vessels,
Inc., a Delaware corporation ("OPI" and, together with JRMEHI, JRMHI, JRMI and
Mentor, the "DELAWARE GUARANTORS"). The Indenture is a valid and binding
agreement of the Company and each Guarantor, enforceable in accordance with its
terms, subject to the effects of (a) any applicable bankruptcy, insolvency,
reorganization, fraudulent conveyance, moratorium and other laws relating to or
affecting creditors' rights generally, (b) general principles of equity
(regardless of whether enforcement is considered in a proceeding in equity or at
law) and (c) any implied covenants of good faith and fair dealing.

         B.       When executed and authenticated in accordance with the
provisions of the Indenture and delivered to and paid for by the Initial
Purchaser in accordance with the terms of the Purchase Agreement, the Securities
will be entitled to the benefits of the Indenture and will be valid and binding
obligations of the Company, enforceable in accordance with their terms, subject
to the effects of (a) any applicable bankruptcy, insolvency, reorganization,
fraudulent conveyance, moratorium and other laws relating to or affecting
creditors' rights generally, (b) general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law) and (c)
any implied covenants of good faith and fair dealing.

         C.       The Initial Guarantee of each of the Delaware Guarantors has
been duly authorized, executed and delivered by such Delaware Guarantor. When
the Securities have been duly issued, executed and authenticated in accordance
with the provisions of the Indenture and delivered to and paid for by the
Initial Purchaser in accordance with the terms of this Agreement, the Initial
Guarantee of each Guarantor will constitute a valid and legally binding
obligation of each Guarantor, enforceable in accordance with its terms, subject
to the effects of (a) any applicable bankruptcy, insolvency, reorganization,
fraudulent conveyance, moratorium and other laws relating to or affecting
creditors' rights generally, (b) general principles of equity (regardless of
whether enforcement is considered in a



proceeding in equity or at law) and (c) any implied covenants of good faith and
fair dealing.

         D.       When the Exchange Securities are issued, executed and
authenticated in accordance with the terms of the Exchange Offer and the
Indenture, the Exchange Securities will be entitled to the benefits of the
Indenture and will be the valid and binding obligations of the Company,
enforceable against the Company in accordance with their terms, subject to the
effects of (a) any applicable bankruptcy, insolvency, reorganization, fraudulent
conveyance, moratorium and other laws relating to or affecting creditors' rights
generally, (b) general principles of equity (regardless of whether enforcement
is considered in a proceeding in equity or at law) and (c) any implied covenants
of good faith and fair dealing.

         E.       The Exchange Guarantee of each of the Delaware Guarantors has
been duly authorized by such Delaware Guarantor. When the Exchange Securities
have been duly issued, executed and authenticated in accordance with the terms
of the Exchange Offer and the Indenture, and when the Exchange Guarantees have
been duly executed and delivered in accordance with the terms of the Exchange
Offer and the Indenture, the Exchange Guarantee of each Guarantor will
constitute a valid and legally binding obligation of such Guarantor, enforceable
in accordance with its terms, subject to the effects of (a) any applicable
bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and
other laws relating to or affecting creditors' rights generally, (b) general
principles of equity (regardless of whether enforcement is considered in a
proceeding in equity or at law) and (c) any implied covenants of good faith and
fair dealing.

         F.       Each of the Security Documents to which a Delaware Guarantor
is a party has been duly authorized, executed and delivered by such Delaware
Guarantor. Each of the New York or U.S. maritime law governed Security Documents
to which either the Company or a Guarantor is a party is a valid and binding
agreement of such entity, enforceable in accordance with its terms, subject to
the effects of (a) any applicable bankruptcy, insolvency, reorganization,
fraudulent conveyance, moratorium and other laws relating to or affecting
creditors' rights generally, (b) general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law) and (c)
any implied covenants of good faith and fair dealing. The Pledge Agreement is
effective to create, in favor of the Trustee for the benefit of the Secured
Parties, as security for the Secured Obligations, a valid security interest
under Article 9 of the Uniform Commercial Code as in effect in the State of New
York (the "NEW YORK UCC") in all of the respective rights, titles and interests
of the Company and the Guarantors party thereto in the Pledged Equity Interests
(as such term is defined in the Security Documents) listed on Schedule 1 to the
Pledge Agreement. Assuming that certificates evidencing all the Pledged Equity
Interests, in each

                                       2



case accompanied by instruments of transfer in blank duly executed, have been
delivered on or prior to the date hereof to the Trustee, and have been
continuously held by the Trustee since such delivery, in each case in the State
of New York, (i) the security interest in the Pledged Equity Interests is
perfected by control (within the meaning of Section 8-106 of the New York UCC)
of such Pledged Equity Interests and (ii) assuming the absence of notice of any
adverse claim thereto on the part of any Secured Party, the Trustee will be a
protected purchaser (within the meaning of Section 8-303(a) of the New York UCC)
of such security interest in such Pledged Equity Interests.

         G.       No consent, approval, authorization or order of, or
qualification with, any U.S. or Texas governmental body or agency is required
for the performance by the Company or any Guarantor of its obligations under the
Purchase Agreement, the Indenture, the Registration Rights Agreement, the
Security Documents or the Securities, except such as may be required by the
securities or Blue Sky laws of the various states in connection with the offer
and sale of the Securities and by Federal and state securities laws with respect
to the Company's obligations under the Registration Rights Agreement.

         H.       The Company is not, and after giving effect to the offering
and sale of the Securities and the application of the proceeds thereof as
described in the Final Memorandum will not be, required to register as an
"investment company" as such term is defined in the Investment Company Act of
1940, as amended.

         I.       The statements relating to legal matters, documents or
proceedings included in the Final Memorandum under the caption "Description of
Notes" fairly summarize in all material respects such matters, documents or
proceedings.

         J.       Based upon (A) the accuracy of the representations and
warranties of the Company in Sections 1(w), 1(x) or 1(z) of the Purchase
Agreement, (B) compliance by the Company with 6(f), 6(g) and 6(j) of the
Purchase Agreement, (C) compliance by the Initial Purchaser in Section 7 of the
Purchase Agreement, (D) compliance by the Initial Purchaser with the offering
and transfer procedures described in the Final Memorandum, (E) the accuracy of
the representations and warranties made in accordance with the Final Memorandum
by the investors to whom you initially resell Securities and (F) receipt by the
investors to whom you initially resell Securities of copies of the Final
Memorandum prior to the effectiveness of such resale, it is not required in
connection with the offer, sale and delivery of the Securities to the Initial
Purchaser under the Purchase Agreement or in connection with the initial resale
of such Securities by the Initial Purchaser in accordance with Section 7 of the
Purchase Agreement to register the Securities under the Securities Act of 1933
or to qualify the Indenture under the Trust Indenture Act of 1939, it being
understood that no opinion is expressed as to any subsequent resale of any
Security.

                                       3



         K.       Nothing has come to the attention of such counsel that causes
such counsel to believe that the Final Memorandum (except for the financial
statements, the notes thereto and the auditors' report thereon, and financial
schedules and other accounting, financial and statistical data, as to which such
counsel need not comment) when issued contained, or as of the date such opinion
is delivered contains, any 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.

         Such counsel may state that they have participated in conferences with
officers and other representatives of the Company, representatives of the
independent public accountants for the Company, your representatives and your
counsel at which conferences the contents of the Final Memorandum and related
matters were discussed, and that they did not independently verify the
information in the Final Memorandum and are not passing upon, and do not assume
any responsibility for, the accuracy, completeness or fairness of the statements
contained in the Final Memorandum (except to the extent set forth in paragraph I
above).

         In giving the foregoing opinions, such counsel may rely on certificates
of representatives of the Company and the Guarantors and of public officials, as
well as the representations and warranties contained in this Agreement, with
respect to the accuracy of the factual matters contained therein, and may state
that the opinions assume (i) that each party to, or issuer of, as applicable,
the Purchase Agreement, the Registration Rights Agreement, the Indenture, the
Securities, the Initial Guarantees, the Exchange Securities, the Exchange
Guarantees and the Security Documents (collectively, the "Transaction
Documents"), other than the Delaware Guarantors, has all necessary power and
authority to enter into the Transaction Documents and to perform its obligations
thereunder, (ii) the due authorization, execution and delivery of the
Transaction Documents by each party thereto (other than the Delaware
Guarantors), (iii) that each Transaction Document constitutes the valid and
legally binding obligation of each party thereto (other than the Company and the
Guarantors), and (iv) the genuineness of all signatures, the conformity to
authentic, original documents of all documents submitted to such counsel as
certified or photostatic copies and the authenticity of all documents submitted
to such counsel as originals.

         In giving the foregoing opinions, such counsel may further state that,
except where otherwise expressly stated, the opinions expressed are based on and
are limited to the laws of the State of Texas, the General Corporation Law of
the State of Delaware and the contract law of the State of New York, in each
case as currently in effect.

                         OPINION OF JOHN T. NESSER, III

The opinion of John T. Nesser, III, to be delivered pursuant to Section 5(d) of
the Purchase Agreement shall be to the effect that:

         A.       Each of the Delaware Guarantors has been duly incorporated, is
validly existing as a corporation in good standing under the laws of the
jurisdiction of its incorporation, and has the corporate power or other
organizational power and authority to own its property and to conduct its
business as described in the Final Memorandum; all of the issued shares of
capital stock of each of the Delaware Guarantors have been duly and validly
authorized and issued, are fully paid and nonassessable, and (except as set
forth in the Final Memorandum or contemplated by the Security Documents) are
owned directly or indirectly by the Company, free and clear of all liens,
encumbrances, equities or similar claims.

         B.       (i) None of the Delaware Guarantors is in violation of its
certificate of incorporation or bylaws, in each case as amended to date, (ii) to
the knowledge of such counsel, neither the Company nor any Material Subsidiary
is in default in the performance or observance of any obligation, agreement,
covenant or condition contained in any indenture, mortgage, loan agreement,
note, lease or other agreement or instrument to which the Company or any of the
Material Subsidiaries is a party or by which it or any of them may be bound, or
to which any of their property or assets is subject, except in the case of
clause (ii) above for any such defaults, as are disclosed in the Final
Memorandum and any such defaults that would not have a Material Adverse Effect
and (iii) to the knowledge of such counsel neither the Company nor any Material
Subsidiary is in violation of any applicable law, rule or regulation, or any
judgment, order or decree of any court with jurisdiction over the Company or any
subsidiary of the Company, or other governmental or regulatory authority with
jurisdiction over the Company or any of its subsidiaries, except for any such
defaults that would not have a Material Adverse Effect.

         C.       The Company and the Material Subsidiaries possess such
certificates, authorizations or permits issued by the appropriate state or
federal regulatory agencies or bodies necessary to conduct the respective
businesses now operated by them, except for such certificates, authorizations or
permits of which the failure by the Company to possess would not have a Material
Adverse Effect, and, to the knowledge of such counsel, except as disclosed in
the Final Memorandum, none of the Company or any of the Material Subsidiaries
has received any notice of proceedings relating to the revocation or
modification of any such certificate, authority or permit which, if the subject
of an unfavorable decision, ruling or finding, would have a Material Adverse
Effect.



         D.       Except as disclosed in the Final Memorandum, there are no
legal or governmental proceedings pending or, to the knowledge of such counsel,
threatened to which the Company or any of its subsidiaries is a party or to
which any of the properties of the Company or any of its subsidiaries is subject
other than proceedings described in the Final Memorandum and proceedings that
would not have a Material Adverse Effect, or have a material adverse effect on
the power or ability of the Company to perform its obligations under this
Agreement, the Indenture, the Registration Rights Agreement, the Security
Documents or the Securities or to consummate the transactions contemplated by
the Final Memorandum.

         E.       The statements in the Final Memorandum under the captions
"Business--Legal Proceedings," "Business--Governmental Regulation" and
"Transactions with Affiliates" are accurate and fairly summarize in all material
respects the matters referred to therein.

         F.       The execution and delivery by the Company and each Delaware
Guarantor of, and the performance by the Company of its obligations under, the
Purchase Agreement, the Registration Rights Agreement, the Indenture, the
Securities and the Security Documents will not contravene any provision of
applicable law or, to the knowledge of such counsel, any indenture, mortgage,
loan agreement, note, lease or other instrument binding upon the Company or any
of its subsidiaries that is material to the Company and its subsidiaries, taken
as a whole, or, to the knowledge of such counsel, any judgment, order or decree
of any governmental body, agency or court having jurisdiction over the Company
or any subsidiary, except for any such contravention as would not have a
Material Adverse Effect.

         G.       Nothing has come to the attention of such counsel that causes
such counsel to believe that the Final Memorandum (except for the financial
statements, the notes thereto and the auditors' report thereon, and financial
schedules and other accounting, financial and statistical data included therein,
as to which such counsel need not comment) when issued contained, or as of the
date such opinion is delivered contains, any 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.

         In giving the foregoing opinions, such counsel may state that, except
where otherwise expressly stated, the opinions expressed are based on and are
limited to the laws of the State of Louisiana and the General Corporation Law of
the State of Delaware, in each case as currently in effect.

                                       2



         Such counsel may also state that phrases such as "to my knowledge,"
"known to me" and those with equivalent words refer to the conscious awareness
of information by such counsel, without any independent investigation.

                                                                     EXHIBIT C-1

                          OPINION OF DURLING & DURLING

The opinion of the counsel for the Company, to be delivered pursuant to Section
5(e) of the Purchase Agreement shall be to the effect that:

MORGAN STANLEY etc.

Gentlemen:

         This opinion is furnished to you pursuant to Section 5(e) of the
Purchase Agreement dated as of November 21, 2003 (the "PURCHASE AGREEMENT",
between J. Ray McDermott, S. A., a Panamanian corporation (the "COMPANY") and
Morgan Stanley & Co. Incorporated (the "Initial Purchaser") of US$ 200,000,000
principal amount of ____% Senior Secured Notes due 2013 (the "SECURITIES") to be
issued pursuant to the provisions of an Indenture to be dated December 8, 2003
(the "INDENTURE") among the Company, each of the subsidiaries of the Company
namely, J. Ray McDermott International, Inc. ("JRMII"), J. Ray McDermott
Contractors, Inc. ("JRMCI"), J. Ray McDermott Middle East, Inc. ("JRMMEI") and
Hydro Marine Services, Inc. ("HYDRO MARINE") (collectively, the "PANAMANIAN
GUARANTORS") and The Bank of New York, as Trustee (the "TRUSTEE").

         We have acted as Panamanian counsel to the Company and the Panamanian
Guarantors in connection with the execution and delivery by the Company and the
Panamanian Guarantors of the Purchase Agreement, the Indenture, the Registration
Rights Agreement, the Security Documents, the Exchange Securities, and the
Securities. In that regard, we have examined originals or copies, certified or
otherwise identified to our satisfaction of such documents, corporate records,
certificates of public officials and other instruments and have conducted such
other investigations of fact and law as we have deemed necessary for the purpose
of this opinion.

         In rendering this opinion we have relied on certificates of
representatives of the Company and the Guarantor and of public officials, as
well as the representations and warranties contained in the Purchase Agreement,
with respect to the accuracy of the factual matters contained therein, and have
assumed (i) that each party to, or issuer of, as applicable, the Purchase
Agreement, the Registration Rights Agreement, the Indenture, the Securities, the
Initial Guarantees, the Exchange Securities, the Exchange Guarantees and the
Security Documents (collectively the "Transaction Documents"), other than the
Company and the Panamanian Guarantors, has all necessary power and authority to
enter into the Transaction Documents and to perform its obligations thereunder,
(ii) the due



authorization, execution and delivery of the Transaction Documents by each party
thereto (other than the Company and the Panamanian Guarantors) and (iii) the
genuineness of all signatures, the conformity to authentic, original of all
documents submitted to us as certified or photostatic copies and the
authenticity of all documents submitted to us as originals. Further, we have
conducted no independent, factual investigation of our own, but rather have
relied solely upon the foregoing documents, the statements and information set
forth therein and the additional matters recited or assumed therein, all of
which we assume to be true, complete and accurate in all material respects.

         Based on the foregoing, we are of the opinion that:

         (a)      The Company has been duly incorporated, is validly existing as
a corporation in good standing under the laws of the Republic of Panama, and has
the corporate power and authority to own its property and to conduct its
business as described in the Final Memorandum.

         (b)      Each of JRMII, JRMCI, JRMMEI and Hydro Marine has been duly
incorporated, is validly existing as a corporation in good standing under the
laws of the Republic of Panama, and has the corporate or other organizational
power and authority to own its property and to conduct its business as described
in the Final Memorandum. Except as described in the Final Memorandum, all of the
issued and outstanding stock or ownership interests of each Panamanian Guarantor
has been duly authorized and validly issued, is fully paid and nonassessable,
and (except as set forth in the Final Memorandum or contemplated by the Security
Documents) is owned directly or indirectly by the Company, free and clear of all
liens, encumbrances, equities or similar claims.

         (c)      The execution and delivery of each of the Purchase Agreement,
the Registration Rights Agreement and the Indenture has been duly authorized by
the Company and the Panamanian Guarantors

         (d)      The Securities and the Exchange Securities have been duly
authorized by the Company.

         (e)      The execution and delivery of the Initial Guarantee of each of
the Panamanian Guarantors has been duly authorized by such Panamanian Guarantor.

         (f)      The Exchange Guarantee of each of the Panamanian Guarantors
has been duly authorized by such Panamanian Guarantor.

         (g)      The execution and delivery of each of the Security Documents
to which either the Company or a Panamanian Guarantor is a party has been duly
authorized by such entity.

                                       2



         (h)      Except for the proper notation in the Stock Register of the
Company and of each of the Panamanian Guarantors it is not necessary or
advisable under the law of Panama that any document be filed, registered or
recorded in any public office of Panama, or any other actions be taken in Panama
in order to ensure the validity, effectiveness, priority, perfection,
admissibility into evidence or enforceability against third parties of the
Pledge Agreement under the laws of Panama.

         (i)      The execution and delivery by the Company and the Panamanian
Guarantors of, and the performance by the Company and the Panamanian Guarantors
of its obligations under, the Purchase Agreement, the Indenture, the
Registration Rights Agreement, the Security Documents, the Exchange Securities
and the Securities will not contravene any provision of applicable law or the
articles of incorporation or by-laws of the Company or, to the best of our
knowledge, any indenture, mortgage, loan, note, lease, agreement or other
instrument binding upon the Company or any of its subsidiaries that is material
to the Company and its subsidiaries, taken as a whole, or, to the best of our
knowledge, any judgment, order or decree of any governmental body, agency or
court having jurisdiction over the Company or any subsidiary, and no consent,
approval, authorization or order of, or qualification with, any governmental
body or agency of the Republic of Panama is required for the issue and sale of
the Securities or the consummation by the Company of the transactions
contemplated by the Purchase Agreement.

         (j)      None of the Company or any of the Panamanian Guarantors is in
violation of its organizational documents, in each case as amended to date.

         (k)      The statements in the Final Memorandum under the caption
"Certain Tax Considerations," insofar as such statements constitute a summary of
the Panamanian tax laws referred to therein, are accurate and fairly summarize
in all material respects the Panamanian tax laws referred to therein.

         (l)      The choice of New York law as the governing law of the Pledge
Agreement and the U.S. Mortgages is a valid choice of law and will be recognized
and given effect to by the courts of Panama.

         (m)      The irrevocable submission by the Company and the Panamanian
Guarantors to the non-exclusive jurisdiction of the Supreme Court of the State
of New York sitting in New York County and of the United States District Court
of the Southern District of New York is a valid submission to the jurisdiction
of such courts.

         (n)      A final and conclusive judgment obtained in the Supreme Court
of the State of New York sitting in New York County, the United States District
Court of the Southern District of New York and any appellate court or body

                                       3



thereto against the Company or the Panamanian Guarantors, arising out of or in
relation to the Security Documents would be enforceable against the Company and
the Panamanian Guarantors in the courts of Panama without further review of the
merits, provided t hat the judgment of Panamanian courts would be reciprocally
recognized, conclusive and enforceable in said court sitting in the State of New
York or outside Panama. The Supreme Court of Panama is authorized to issue a
writ of exequatur in respect of final judgment rendered in a foreign
jurisdiction only if (a) such judgment arises out of an in personam action, (b)
the Party against whom the judgment was rendered, or its agent, was personally
served in such action within such foreign jurisdiction, (c) the obligation in
respect of which the judgment was obtained is lawful in Panama and (d) such
judgment has been properly authenticated by diplomatic or consular officers of
Panama.

         (o)      There is no tax, deduction or withholding imposed by the
government of Panama or any political subdivision thereof or therein either (i)
on or by virtue of the execution or delivery of the Security Documents or (ii)
on any payment to be made by the Company or the Panamanian Guarantors under the
Security Documents.

         We are members of the bar of Panama and the opinions expressed above
are limited to matters governed by Panamanian law. This opinion is to be
governed by and construed in accordance with the laws of Panama and is limited
to and is given on the basis of the current law and practice in Panama.

                                       Very truly yours,

                                       4



                                                                     EXHIBIT C-2

                          OPINION OF DURLING & DURLING

The opinion of the counsel for the Company, to be delivered pursuant to Section
5(e) of the Purchase Agreement shall be to the effect that:

To Morgan Stanley etc.

Ladies and Gentlemen:

         This opinion is furnished to you pursuant to Section 5(e) of the
Purchase Agreement dated as of November 21, 2003 (the "Purchase Agreement",
between J. Ray McDermott, S. A., a Panamanian corporation (the "Company") and
Morgan Stanley & Co. Incorporated (the "Initial Purchaser") of US$ 200,000,000
principal amount of ____% Senior Secured Notes due 2013 (the "Securities") to be
issued pursuant to the provisions of an Indenture to be dated December 8, 2003
(the "Indenture") among the Company, each of the subsidiaries of the Company
namely, J. Ray McDermott International, Inc. ("JRMII"), J. Ray McDermott
Contractors, Inc. ("JRMCI"), J. Ray McDermott Middle East, Inc. ("JRMMEI") and
Hydro Marine Services, Inc. ("Hydro Marine") (collectively, the "Panamanian
Guarantors") and The Bank of New York, as Trustee (the "Trustee").

         We have acted as Panamanian counsel to the Panamanian Guarantors in
connection with the execution and delivery of the First Naval Fleet Mortgages
described in Schedule attached hereto (collectively, the "Panamanian Fleet
Mortgages"). In that regard, we have examined originals or copies, certified or
otherwise identified to our satisfaction, of such documents, corporate records,
certificates of public officials and other instruments for the purpose of this
opinion.

         In rendering this opinion we have assumed (i) that each party to the
Panamanian Fleet Mortgages has all necessary power, authority and legal right to
enter into the Panamanian Fleet Mortgages to which is a party and to perform its
obligation thereunder, (ii) the due authorization, execution and delivery of the
Panamanian Fleet Mortgages by each party hereto, (iii) that each Panamanian
Fleet Mortgages constitutes the legal, valid, binding and enforceable obligation
of each party thereto, and (iv) the genuineness of all signatures, the
conformity to authentic, original documents of all documents submitted to us as
certified or photostatic copies and the authenticity of all documents submitted
to us as originals. As to certain factual matters, we are relying on
certificates of officers of the Panamanian Guarantors. Further, we have
conducted no



independent, factual investigation of our own, but rather have relied solely
upon the foregoing documents, the statements and information set forth therein
and the additional matters recited or assumed therein, all of which we assume to
be true, complete and accurate in all material respects.

         Based on the foregoing, we are of the opinion that:

         1.       Each of the Panamanian Guarantors is a corporation validly
existing and in good standing under the laws of Panama and has the corporate
power and authority (a) to own its property and assets and to carry on its
business as now conducted and as proposed to be conducted and (b) to execute,
deliver and perform its obligations under each of the Panamanian Fleet Mortgages
to which it is a party.

         2.       The execution, delivery and performance by the Panamanian
Guarantors of each of the Panamanian Fleet Mortgages to which it is a party and
the transactions contemplated thereby, (a) have been duly authorized by all
requisite corporate and, if required, stockholder action and (b) will not
violate any provision of Panamanian law, statute, rule or regulation or the
certificate of incorporation, by-laws or other constitutive documents of each of
the Panamanian Guarantors.

         3.       Each Panamanian Fleet Mortgage constitutes a legal, valid and
binding obligation of the Panamanian Guarantors party thereto, enforceable
against such Panamanian Guarantors in accordance with its terms, subject to
applicable bankruptcy, insolvency, reorganization and other similar laws
affecting creditors' rights generally and to the applicability of general
principles of equity.

         4.       Each Panamanian Guarantors has record title to 100% of each of
the vessels that is identified as owned by it on Schedule attached hereto and
each vessel is permanently registered in the name of such Panamanian Guarantors
under the Panamanian flag.

         5.       On account of their preliminary registration in the Public
Registry Office of the Republic of Panama, the Panamanian Fleet Mortgages
constitute legal and valid mortgages over the vessels described therein and will
so constitute as long as the Panamanian Fleet Mortgages are filed for final
registration at the Panama Public Registry Office within six months from the
date of its preliminary registration and the definite registration is completed.
Upon such permanent registration, the Panamanian Fleet Mortgages will rank from
the date of preliminary registration as first mortgages over the vessels
described therein.

         6.       Other than the permanent registration of the Panamanian Fleet
Mortgages in the Public Registry Office of Panama, no action, consent or
approval of, registration or filing with or any other action by any Panamanian
governmental authority or regulatory body is or will be required in connection

                                       2



with the Panamanian Fleet Mortgages or the exercise by the Mortgagee of its
rights thereunder.

         7.       Save for customary mortgage registration fees, and a stamp tax
at the rate of US$0.10 for each US$100 of the face value of the obligations
evidenced in the Panamanian Fleet Mortgages which may be levied in the event
that any of the Panamanian Fleet Mortgages is submitted before any
administrative or judicial authority in Panama, no stamp, registration or
similar tax or charge is required to be paid in the Republic of Panama on or in
relation to any of the Panamanian Fleet Mortgages. Payment of the above stamp
tax is not applicable upon registration of the Panamanian Fleet Mortgages.

         8.       No taxes of the Republic of Panama are imposed by withholding
or otherwise on any payment to be made by any Panamanian Guarantors under any of
the Panamanian Fleet Mortgages or are imposed on or by virtue of the execution
or delivery of the Panamanian Fleet Mortgages by any Panamanian Guarantors.

         We are members of the bar of Panama, and the opinions expressed above
are limited to matters governed by Panamanian law. This opinion is to be
governed by and construed in accordance with the laws of Panama and is limited
to and is given on the basis of the current law and practice in Panama.

                                       Very truly yours,

                                       3



                                                                     EXHIBIT C-3

                               OPINION OF WALKERS

The opinion of Walkers, to be delivered pursuant to Section 5(e) of the Purchase
Agreement shall be to the effect that:

1)       J. Ray McDermott International Vessels Limited ("JRMIVL") has been duly
         incorporated, is validly existing as an exempted company in good
         standing under the laws of the Cayman Islands, and has the corporate or
         other organizational power and authority to own its property and to
         conduct its business. Based solely on our review of the Register of
         Members and except as described in the Final Memorandum, all of the
         issued and outstanding ownership interests of JRMIVL has been duly
         authorized and validly issued, is fully paid and nonassessable, and
         (except as set forth in the Final Memorandum or contemplated by the
         Security Documents) is owned free and clear of all liens, encumbrances,
         equities or similar claims.

2)       Each of the Purchase Agreement, the Registration Rights Agreement and
         the Indenture has been duly authorized and executed by JRMIVL.

         by JRMIVL.

5)       Each of the Security Documents to which JRMIVL is a party has been duly
         authorized and executed by JRMIVL.

         Indenture, the Registration Rights Agreement and the Security
         Documents, the consummation of the transactions contemplated thereby
         and the compliance by JRMIVL with the terms and provisions thereof do
         not:

         (a)      contravene any law, public rule or regulation applicable to
         JRMIVL which is currently in force; or

         (b)      contravene the memorandum and articles of association of
         JRMIVL.

7)       Neither the execution, delivery or performance of any of the Purchase
         Agreement, the Indenture, the Registration Rights Agreement and the

         performance of any of the transactions contemplated thereby by JRMIVL,



         requires the consent or approval of, the giving of notice to, or the
         registration with, or the taking of any other action in respect of any

         could in the future become imposed, in connection with the enforcement
         or admissibility in evidence of the Security Documents or on any
         payment to be made by JRMIVL or any other person pursuant to the
         Documents. The Cayman Islands currently have no form of income,
         corporate or capital gains tax and no estate duty, inheritance tax or
         gift tax.

9)       A judgment obtained in a foreign court will be recognized and enforced
         in the courts of the Cayman Islands without any re-examination of the
         merits at common law, by an action commenced on the foreign judgment
         debt in the Grand Court of the Cayman Islands, where the judgment is
         final and in respect of which the foreign court had jurisdiction over
         the defendant according to Cayman Islands conflict of law rules and
         which is conclusive, for a liquidated sum not in respect of penalties
         or taxes or a fine or similar fiscal or revenue obligations, and which

         is contrary to natural justice or the public policy of the Cayman
         Islands.

10)      Other than to enter particulars of the security interest created by

         Companies Law (2003 Revision) of the Cayman Islands, it is not
         necessary or advisable under the laws of the Cayman Islands that any of
         the Documents or any document relating thereto be registered or
         recorded in any public office or elsewhere in the Cayman Islands in
         order to ensure the validity, effectiveness or enforceability of any of
         the Documents.

11)      It is not necessary under the law of the Cayman Islands (i) in order to
         enable any party to the agreement to enforce their rights under the
         Security Documents or (ii) solely by reason of the execution, delivery
         and performance of the Security Documents that the parties to the
         Security Documents should be licensed, qualified or otherwise entitled
         to carry on business in the Cayman Islands or any other political
         subdivision thereof. Except as hereinafter indicated, it is not
         necessary or advisable in order to ensure the legality, validity,
         enforceability or admissibility in evidence of the Security Documents
         in the Cayman Islands that the same be filed, notarized, recoded or
         enrolled with any government authority.

                                       2



12)      JRMIVL has executed an effective submission to the jurisdiction of the
         courts of the jurisdictions specified in the Security Documents.

13)      JRMIVL is subject to civil and commercial law with respect to its
         obligations under the Security Documents and neither JRMIVL nor any of
         its assets is entitled to immunity from suit or enforcement of a
         judgment on the grounds of sovereignty or otherwise in the courts of
         the Cayman Islands in proceedings against JRMIVL in respect of any
         obligations under the Purchase Agreement, the Indenture, the
         Registration Rights Agreement and the Security Documents, which
         obligations constitute private and commercial acts rather than
         governmental or public acts.

                                                                     EXHIBIT D-1

                        OPINION OF DAVIS POLK & WARDWELL

         The opinion of Davis Polk & Wardwell to be delivered pursuant to
Section 5(f) of the Purchase Agreement shall be to the effect that:

         A.       The statements relating to legal matters, documents or
proceedings included in the Final Memorandum under the captions "Description of
Notes," "Private Placement" and "Transfer Restrictions," fairly summarize in all
material respects such matters, documents or proceedings.

         B.       Nothing has come to the attention of such counsel to cause
such counsel to believe that (except for the financial statements and financial
schedules and other accounting, financial and statistical data, as to which such
counsel need not express any belief) the Final Memorandum when issued contained,
or as of the date such opinion is delivered contains, any 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.

         With respect to the matters referred to in the paragraph above, Davis
Polk & Wardwell may state that their beliefs are based upon their participation
in the preparation of the Final Memorandum (and any amendments or supplements
thereto) and review and discussion of the contents thereof, but are without
independent check or verification except as specified.

         C.       Based upon the representations, warranties and agreements of
the Company in Sections 1(w), 1(x), 1(z), 6(f), 6(g) and 6(j) of the Purchase
Agreement and of the Initial Purchaser in Section 7 of the Purchase Agreement,
it is not necessary in connection with the offer, sale and delivery of the
Securities to the Initial Purchaser under the Purchase Agreement or in
connection with the initial resale of such Securities by the Initial Purchaser
in accordance with Section 7 of the Purchase Agreement to register the
Securities under the Securities Act of 1933, it being understood that no opinion
is expressed as to any subsequent resale of any Security.
