ARTICLE II.Representations, Warranties and Covenants of the Collateral Vessel Owner

{N3767794.5}    3    

The Collateral Vessel Owner represents, warrants, covenants and agrees with the Mortgagee as follows:

Section 1.The Collateral Vessel Owner is a limited liability company formed and existing under the laws of Delaware. The Collateral Vessel Owner has full power and authority to own and mortgage the Collateral Vessels; has full right and entitlement to register the Collateral Vessels in the Collateral Vessel Owner’s name under the flag of the United States of America and all corporate (or equivalent) action necessary and required by law for the execution and delivery of this Mortgage has been duly and effectively taken. This Mortgage is and will be the legal, valid and binding obligation of the Collateral Vessel Owner enforceable in accordance with its terms, subject as to enforcement only to bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and equitable principles.

Section 2.In the event of any conflict or inconsistency between this Mortgage and the Credit Agreement, the Guaranty and Collateral Agreement or any other Credit Document, the provisions of this Mortgage shall prevail, but only to the extent required by United States law.

The Obligations hereby secured are in United States Dollars and the symbol “$” when used herein shall mean such United States Dollars. Notwithstanding fluctuations in the value or rate of United States Dollars in terms of gold or any other currency, all payments hereunder or otherwise in respect of the Obligations hereby secured shall be payable in terms of United States Dollars when due and in United States Dollars when paid, whether such payment is made before or after the due date.

Section 4.Neither the Collateral Vessel Owner, any charterer, the master of the Collateral Vessels nor any other person has or shall have any right, power or authority to create, incur or permit to be placed or imposed or continued upon any Collateral Vessel any lien whatsoever other than Permitted Liens.

Section 5.The Collateral Vessel Owner will carry, and shall retain, a properly certified copy of this Mortgage with each Collateral Vessel’s marine papers and will cause such certified copy to be placed on board each Collateral Vessel to the extent there is a suitable place on board the Collateral Vessel to carry such certified copy, and such certified copy shall be exhibited to any and all persons having business therewith which might give rise to any lien on such Collateral Vessel other than Permitted Liens, and to any representative of the Mortgagee;

{N3767794.5}    4    

and to the extent there is a suitable place on board the Collateral Vessel to do so, the Collateral Vessel Owner will place and keep prominently displayed on each Collateral Vessel a framed printed notice in plain type reading as follows:

“NOTICE OF MORTGAGE”

“This Vessel is covered by a Fleet Mortgage (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Mortgage”) in favor of JPMorgan Chase Bank, N.A., as Security Trustee, under authority of 46 U.S.C. §31301 et seq. Under the terms of said Mortgage, neither the owner, any charterer, the master of this Vessel nor any other person has any right, power or authority to create, incur or permit to be imposed upon this Vessel any other lien whatsoever except Permitted Liens (as defined in the Mortgage), copies of which are available on board for inspection upon the request of any party having business with this Vessel.”

Section 6.(a) The Collateral Vessel Owner lawfully owns and is lawfully possessed of the Collateral Vessels free and clear of all liens, mortgages, taxes and encumbrances except Permitted Liens and the Collateral Vessel Owner does hereby warrant and will defend the title and possession thereof and to every part thereof for the benefit of the Mortgagee against the claims and demands of all Persons whomsoever (taking into account Permitted Liens).

Section 7.(a) To the extent provided for in any Credit Document and subject to Article IV, Section 6, this Mortgage shall extend to and constitute a lien upon, and the Collateral Vessel Owner hereby grants the Mortgagee a security interest in, proceeds resulting from or relating to any Disposition in respect of any Collateral Vessel as security for the Obligations hereby secured.

ARTICLE III.Events of Default and Remedies.

Section 1.The occurrence and continuation of an “event of default” under the Credit Agreement shall constitute an “Event of Default” under this Mortgage.

Upon the occurrence and during the continuance of any Event of Default, the security constituted by this Mortgage shall become immediately enforceable in accordance with the terms of the Credit Agreement and, without limitation, the enforcement remedies specified can be exercised irrespective of whether or not the Mortgagee has exercised the right of acceleration under the Credit Agreement or any of the other Credit Documents and the Mortgagee shall have the right, for the benefit of the Secured Parties, to:

{N3767794.5}    5    

(a)exercise all of the rights and remedies in foreclosure and otherwise given to mortgagees by the provisions of the laws of the United States or of any other jurisdiction where the applicable Collateral Vessel may be found;

(b)bring suit at law, in equity or in admiralty, as it may be advised, to recover judgment for the Obligations hereby secured;

(c)take and enter into possession of any Collateral Vessel, at any time, wherever the same may be, without legal process and without being responsible for loss or damage, and the Collateral Vessel Owner or other person in possession forthwith upon demand of the Mortgagee shall surrender to the Mortgagee possession of any Collateral Vessel;

(d)without being responsible for loss or damage (except to the extent such loss or damage results from the Mortgagee’s gross negligence, willful misconduct, violation of law or willful breach of its obligations hereunder, as determined by a court of competent jurisdiction in a final non-appealable judgment), the Mortgagee may hold, lay up, lease, charter, operate or otherwise use any and all Collateral Vessels for such time and upon such terms as it may deem to be for its best advantage, and demand, collect and retain all day rates, hire, freights, earnings, issues, revenues, income, profits, return premiums, salvage awards or recoveries, recoveries in general average, and all other sums due or to become due in respect of any Collateral Vessel or in respect of any insurance thereon from any person whomsoever, accounting only for the net profits, if any, arising from such use of any Collateral Vessel and charging upon all receipts from the use of any Collateral Vessel or from the sale thereof by court proceedings or, pursuant to subsection (e) below, all costs, expenses, charges, damages or losses by reason of such use, provided that the Mortgagee shall provide the Collateral Vessel Owner with a final accounting; and if at any time the Mortgagee shall avail itself of the right herein given it to take any Collateral Vessel, the Mortgagee shall have the right to dock any such Collateral Vessel, for a reasonable time at any dock, pier or other premises of the Collateral Vessel Owner without charge, or to dock it at any other place at the cost and expense of the Collateral Vessel Owner;

(e)sell any and all Collateral Vessels, at any place and at such time as the Mortgagee may specify and in such manner as the Mortgagee may deem advisable, free from any claim by the Collateral Vessel Owner in admiralty, in equity, at law or by statute, at public or private sale, by sealed bids or otherwise, by mailing, by air or otherwise, notice of such sale, whether public or private, addressed to the Collateral Vessel Owner at its last known address, fourteen (14) days prior to the date fixed for entering into the contract of sale; the sale may be held at such place and at such time as the Mortgagee by notice may have specified, or may be adjourned by the Mortgagee from time to time by announcement at the time and place appointed for such sale or for such adjourned sale, and without further notice the Mortgagee may make any such sale at the time and place to which the same shall be so adjourned; and any sale may be conducted without bringing such Collateral Vessel to the place designated for such sale and in such manner as the Mortgagee may deem to be for its best advantage, and the Mortgagee may become the purchaser at any sale. The Collateral Vessel Owner agrees that any sale made in accordance with the terms of this paragraph shall be deemed made in a commercially reasonable manner insofar as it is concerned;

{N3767794.5}    6    

(f)require that all policies, contracts, certificates of entry and other records relating to the insurance with respect to any Collateral Vessel, including, but not limited to, those described in Section 6.5 of the Credit Agreement (the “Insurances”) (including details of and correspondence concerning outstanding claims) be forthwith delivered to the Mortgagee; and

(g)collect, recover, compromise and give a good discharge for any and all monies and claims for monies then outstanding or thereafter arising under the Insurances or in respect of the earnings or any requisition compensation and to permit any brokers through whom collection or recovery is effected to charge the usual brokerage therefor.

Section 2.Any sale of any Collateral Vessel made in pursuance of, and in accordance with, this Mortgage, whether under the power of sale hereby granted or any judicial proceedings, shall operate to divest all right, title and interest of any nature whatsoever of the Collateral Vessel Owner therein and thereto, and shall bar any claim from the Collateral Vessel Owner, its successors and assigns, and all persons claiming by, through or under it. No purchaser shall be bound to inquire whether notice has been given, or whether any default has occurred, or as to the propriety of the sale, or as to the application of the proceeds thereof. In case of any such sale, the Mortgagee, if it is the purchaser, shall be entitled for the purpose of making settlement or payment for the property purchased to use and apply the Obligations hereby secured in order that there may be credited against the amount remaining due and unpaid thereon the sums payable out of the net proceeds of such sale to the Mortgagee after allowing for the costs and expense of sale and other charges; and thereupon such purchaser shall be credited, on account of such purchase price, with the net proceeds that shall have been so credited upon the Obligations hereby secured. At any such sale, the Mortgagee may bid for and purchase such property and upon compliance with the terms of sale may hold, retain and dispose of such property without further accountability therefor.

Section 3.Until the Termination Date (as defined below), the Mortgagee is hereby irrevocably appointed attorney-in-fact of the Collateral Vessel Owner, upon the happening and during the continuance of any Event of Default, to execute and deliver to any purchaser aforesaid, and is hereby vested with full power and authority to make, in the name and in behalf of the Collateral Vessel Owner, a good conveyance of the title to the Collateral Vessels so sold. In the event of any sale of any Collateral Vessel, under any power herein contained, the Collateral Vessel Owner will, if and when required by the Mortgagee, execute such form of conveyance of such Collateral Vessel as the Mortgagee may direct or approve.

Section 4.The Mortgagee is hereby appointed attorney-in-fact of the Collateral Vessel Owner upon the happening and during the continuance of any Event of Default, in the name of the Collateral Vessel Owner to demand, collect, receive, compromise and sue for, so far as may be permitted by law, all day rates, freight, hire, earnings, issues, revenues, income and profits of any Collateral Vessel and all amounts due from underwriters under any insurance thereon as payment of losses or as return premiums or otherwise, salvage awards and recoveries,

{N3767794.5}    7    

recoveries in general average or otherwise, and all other sums due or to become due at the time of the happening and during the continuance of any Event of Default in respect of any Collateral Vessel, or in respect of any insurance thereon, from any person whomsoever, and to make, give and execute in the name of the Collateral Vessel Owner acquittances, receipts, releases or other discharges for the same, whether under seal or otherwise, and to endorse and accept in the name of the Collateral Vessel Owner all checks, notes, drafts, warrants, agreements and other instruments in writing with respect to the foregoing.

Section 5.Whenever any right to enter and take possession of any Collateral Vessel accrues to the Mortgagee as a result of the occurrence and continuance of an Event of Default, it may require the Collateral Vessel Owner to deliver, and the Collateral Vessel Owner shall on demand, at its own cost and expense, deliver to the Mortgagee such Collateral Vessel to a location designated by the Mortgagee as demanded. If the Mortgagee shall be entitled to take any legal proceedings to enforce any right under this Article III, the Mortgagee shall be entitled as a matter of right to the appointment of a receiver of such Collateral Vessel and of the day rates, freights, hire, earnings, issues, revenues, income and profits due or to become due and arising from the operation thereof.

Section 6.To the extent that the Collateral Vessel Owner does not so appear, the Collateral Vessel Owner authorizes and empowers the Mortgagee or its appointees or any of them to appear in the name of the Collateral Vessel Owner, its successors and assigns, in any court of any country or nation of the world where any Collateral Vessel is libeled, attached, detained, seized or levied upon or taken into custody under process or under color of any authority because of or on account of any alleged lien (except for Permitted Liens) against such Collateral Vessel from which such Collateral Vessel has not been released within fifteen (15) days of such libel, attachment, detention, seizure, levy or taking into custody, and to take such proceedings as to them or any of them may seem proper towards the defense of such suit and the purchase or discharge of such Lien, and all expenditures made or incurred by them or any of them for the purpose of such defense or purchase or discharge shall be a debt due from the Collateral Vessel Owner, its successors and assigns, to the Mortgagee, and shall be secured by the lien of this Mortgage in like manner and extent as if the amount and description thereof were written herein.

Section 7.In the event the Mortgagee shall be entitled to exercise any of its remedies under this Article III, the Mortgagee shall have the right to commence proceedings in the courts of any country having competent jurisdiction and, in particular, the Mortgagee shall have the right to arrest and take against any Collateral Vessel and any appurtenant property thereto at whatever place any Collateral Vessel shall be found lying. For purposes of the foregoing, any writ, notice, judgment or other legal process or documents may (without prejudice to any other method of service under applicable law) be served upon the master of any Collateral Vessel (or upon anyone acting as the master) and such service shall be deemed good service on the Collateral Vessel Owner for all purposes.

Section 8.Each and every power and remedy herein given to the Mortgagee shall be cumulative and shall be in addition to every other power and remedy herein given or now or

{N3767794.5}    8    

hereafter existing at law, in equity, in admiralty or by statute, and each and every power and remedy whether herein given or otherwise existing may be exercised from time to time and as often and in such order as may be deemed expedient by the Mortgagee, and the exercise or the beginning of the exercise of any power or remedy shall not be construed to be a waiver of the right to exercise at the same time or thereafter any other power or remedy. The Mortgagee shall not be required or bound to enforce any of its rights under any of the other Credit Documents prior to enforcing its rights under this Mortgage. No delay or omission by the Mortgagee in the exercise of any right or power or in the pursuance of any remedy accruing upon any default as above defined shall impair any such right, power or remedy or be construed to be a waiver of any such Event of Default or to be an acquiescence therein; nor shall the acceptance by the Mortgagee of any security or of any payment of or on account of the Obligations hereby secured maturing after any Event of Default or of any payment on account of any past default be construed to be a waiver of any right to exercise its remedies due to any future Event of Default or of any past Event of Default not completely cured thereby. No consent, waiver or approval of the Mortgagee shall be deemed to be effective unless in writing and duly signed by authorized signatories of the Mortgagee; any waiver by the Mortgagee of any of the terms of this Mortgage or any consent given under this Mortgage shall only be effective for the purpose and on the terms which it is given and shall be without prejudice to the right to give or withhold consent in relation to future matters (which are either the same or different).

Section 9.If at any time after an Event of Default and prior to the actual sale of any Collateral Vessel by the Mortgagee or prior to any enforcement or foreclosure proceedings the Collateral Vessel Owner offers completely to cure all Events of Default and to pay all expenses, advances and damages to the Mortgagee consequent on such Events of Default, with interest with respect to the Collateral Vessel Owner’s obligations as provided herein or in the Credit Agreement as set forth therein, then the Mortgagee may accept such offer and payment and restore the Collateral Vessel Owner to its former position, but such action, if taken, shall not affect any subsequent Event of Default or impair any rights consequent thereon.

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

Section 11.(a) The proceeds of any sale or other disposition of any Collateral Vessel and the net earnings of any charter operation or other use of any Collateral Vessel and any and all other moneys received by the Mortgagee pursuant to or under the terms of this Mortgage or in any proceedings hereunder, the application of which has not elsewhere herein been specifically provided for, shall be applied in the manner provided in Section 8.7 of the Credit Agreement.

(a)To the extent the proceeds of the sale of any Collateral Vessel are not sufficient to pay the aggregate amount of the Obligations hereby secured, any Person liable for the

{N3767794.5}    9    

Obligations hereby secured (including without limitation, the Collateral Vessel Owner and the Guarantors to the extent such Persons are liable) shall remain jointly and severally liable for such deficiency. Without limiting the generality of the foregoing, the rights and remedies of the Mortgagee under this Mortgage and the other agreements, documents and instruments securing or guarantying any of the Obligations hereby secured shall be cumulative, and the exercise or partial exercise of any such right or remedy shall not preclude the exercise of any right or remedy.

Section 12.Until one or more Events of Default shall have happened and be continuing, the Collateral Vessel Owner, subject to the terms and conditions of the Credit Agreement, shall be (a) suffered and permitted to retain actual possession and use of all Collateral Vessels and (b) shall have the right, from time to time in its discretion, and without application to the Mortgagee, and without obtaining a release thereof by the Mortgagee, to dispose of, free from the lien hereof, any boilers, engines, machinery, masts, spars, boats, anchors, cables, chains, rigging, tackle, capstans, outfit, tools, pumps, pumping equipment, apparel, furniture, fittings, equipment , spare parts or any other appurtenances of any Collateral Vessel that are no longer useful, necessary, profitable or advantageous in the operation of such Collateral Vessel, first or simultaneously replacing the same by new boilers, engines, machinery, masts, spars, boats, anchors, cables, chains, rigging, tackle, capstans, outfit, tools, pumps, pumping equipment, apparel, furniture, fittings, equipment, spare parts or any appurtenances of comparable suitability to the Collateral Vessel Owner, which shall forthwith become subject to the lien of this Mortgage.

Notwithstanding the foregoing, in no event shall the Mortgagee exercise any of its remedies under this Article III or any other provision of this Mortgage in a manner which would impair, in any way, the current United States Coast Guard endorsement of any Collateral Vessel.

ARTICLE IV.
Sundry Provisions

Section 1.All of the covenants, promises, stipulations and agreements of the Collateral Vessel Owner contained in this Mortgage shall bind the Collateral Vessel Owner and its successors and assigns and shall inure to the benefit of the Mortgagee and its successors and assigns.
