2.1 Subordination of Subordinated Debt to Senior Debt.

The Subordinated Creditors irrevocably authorize,

- 5 -

empower and direct any debtor, debtor in possession, receiver, trustee, liquidator, custodian, conservator or other Person having authority, to pay or otherwise deliver all such Distributions to the Trustee. The Subordinated Creditors also irrevocably authorize and empower the Trustee, in the name of the Subordinated Creditors, to demand, xxx for, collect and receive any and all such Distributions.

(d) The Subordinated Creditors hereby irrevocably authorize, empower and appoint the Trustee their agent and attorney-in-fact to (i) execute, verify, deliver and file accurate proofs of claim in respect of the Subordinated Debt upon the failure of any Subordinated Creditor promptly to do so prior to 10 days before the expiration of the time to file any such proof of claim and (ii) vote such claim in any such Proceeding upon the failure of any Subordinated Creditor to do so prior to 5 days before the expiration of the time to vote any such claim; provided the Trustee shall have no obligation to execute, verify, deliver, file and/or vote any such proof of claim.

2.3 Subordinated Debt Payment Restrictions.

(a) Notwithstanding the terms of the Subordinated Debt Documents, each Credit Party hereby agrees that it shall not make, and the Subordinated Creditors hereby agree that they will not accept, any Distribution with respect to the Subordinated Debt until the Senior Debt is paid in full in cash and all amounts due on or in respect of Obligations under the Senior Debt Documents have terminated other than Permitted Subordinated Debt Payments; provided, however, that the Credit Parties and the Subordinated Creditors further agree that no Permitted Subordinated Debt Payment may be made by any Credit Party or accepted by the Subordinated Creditors if, at the time of such payment:

(i) a Senior Payment Default exists and such Senior Payment Default shall not have been cured or waived; or

- 6 -

(ii) subject to paragraphs (b) and (d) of this subsection 2.3, (A) the Company and the Subordinated Creditors shall have received a Payment Blockage Notice from the Trustee or any Noteholder stating that a Senior Covenant Default exists or would be created by the making of such payment and (B) each such Senior Covenant Default shall not have been cured or waived.

(b) The Credit Parties may resume Permitted Subordinated Debt Payments (and may make any Permitted Subordinated Debt Payments missed due to the application of paragraph (a) of this subsection 2.3) in respect of the Subordinated Debt or any judgment with respect thereto:

(i) in the case of a Senior Payment Default referred to in clause (i) of paragraph (a) this subsection 2.3, upon a cure, waiver or cessation thereof; or

(ii) in the case of a Senior Covenant Default referred to in clause (ii) of paragraph (a) of this subsection 2.3, upon the earlier to occur of (A) the cure, waiver or cessation of all such Senior Covenant Defaults or (B) 180 days after the date on which the applicable Payment Blockage Notice is received, unless the maturity of the Notes has been accelerated.

(c) No Senior Default shall be deemed to have been waived for purposes of this subsection 2.3 unless and until the Company shall have received a written waiver from the Trustee or Noteholders holding a majority of the outstanding principal amount of Notes.

(d) Notwithstanding any provision of this subsection 2.3 to the contrary:

(i) the Credit Parties shall not be prohibited from making, and the Subordinated Creditors shall not be prohibited from receiving, Permitted Subordinated Debt Payments under clause (ii) of paragraph (a) of this subsection 2.3 for more than an aggregate of 180 days within any period of 365 consecutive days;

(ii) no Senior Covenant Default existing on the date any Payment Blockage Notice is given pursuant to clause (ii) of paragraph (a) of this subsection 2.3 shall, unless the same shall have ceased to exist for a period of at least 45 consecutive days, be used as a basis for any subsequent such notice; and

(iii) the failure of the Credit Parties to make any Distribution with respect to the Subordinated Debt by reason of the operation of this subsection 2.3 shall not be construed as preventing the occurrence of a Subordinated Debt Default under the applicable Subordinated Debt Documents.

- 7 -

2.4 Subordinated Debt Standstill Provisions.

(a) Until the Senior Debt is paid in full in cash and all amounts due on or in respect of Obligations under the Senior Debt Documents shall be terminated, no Subordinated Creditor shall, without the prior written consent of the Trustee, take any Enforcement Action with respect to the Subordinated Debt, until the earliest to occur of the following:

(i) acceleration of the Senior Debt; or

(ii) the passage of 180 days from the delivery of a Subordinated Debt Default Notice to the Trustee if any Subordinated Debt Default described therein shall not have been cured or waived within such period; provided, that the Subordinated Creditors have provided at least 10 days notice to Trustee of their intention to take any such Enforcement Action (such notice may be provided prior to the expiration of the 180 day period referred to above).

Notwithstanding the foregoing, the Subordinated Creditors may file proofs of claim against any Credit Party in any Proceeding involving any Credit Party. Any Distributions or other proceeds of any Enforcement Action obtained by the Subordinated Creditors shall in any event be held in trust by them for the benefit of the Trustee and the Noteholders and promptly paid or delivered to the Trustee for the benefit of the Noteholders in the form received until all Senior Debt is paid in full in cash.

(b) Notwithstanding anything contained herein to the contrary, if following the acceleration of the Senior Debt by the Trustee or the Noteholders such acceleration is rescinded (whether or not any existing Senior Default has been cured or waived), then all Enforcement Actions taken by the Subordinated Creditors shall likewise be rescinded if such Enforcement Action is based solely on clause (i) of paragraph (a) of this subsection 2.4.

2.5 Incorrect Payments. If any Distribution on account of the Subordinated Debt not permitted to be made by the Credit Parties or accepted by the Subordinated Creditors under this Agreement is made and received by the Subordinated Creditors or if the Subordinated Creditors receive proceeds of any Collateral other than as expressly permitted hereunder, such Distribution or proceeds shall not be commingled with any of the assets of the Subordinated Creditors, shall be held in trust by the Subordinated Creditors for the benefit of the Trustee and the Note holders and shall be promptly paid over to the Trustee for application (in accordance with the Senior Debt Documents ) to the payment of the Senior Debt then remaining unpaid, until all of the Senior Debt is paid in full.

2.6 Subordination of Liens and Security Interests; Agreement Not to Contest; Agreement to Release Liens. Until the Senior Debt has been paid in full in cash and all amounts due on or in respect of Obligations under the Senior Debt Documents have terminated, any liens and security interests of the Subordinated Creditors in the Collateral (including any which may exist in breach of the Subordinated Creditors’ agreement pursuant to subsection 3.2(f) or Section 4 of this Agreement) shall be and hereby are subordinated for all purposes and in all respects to the liens and security interests of the Trustee and the Noteholders in the Collateral, regardless of the time, manner or order of perfection of any such liens and security interests and regardless of how acquired, whether by judgment, grant, possession, statute, operation of law or otherwise. The Subordinated Creditors agree that they will not at any time contest the validity, perfection, priority or enforceability of the Senior Debt, the Senior Debt Documents, or the liens and security interests of the Trustee and the Noteholders in the Collateral securing the Senior Debt.

- 8 -

Holders of Senior Debt agree that they will not at any time contest the validity, perfection, priority or enforceability of the Subordinated Debt, the Subordinated Debt Documents, or the liens and security interests of the Subordinated Trustee and the Subordinated Creditors. In the event that the Trustee and the Noteholders release any liens or security interests in the Collateral, then the liens, if any, of the Subordinated Creditors on such Collateral shall be automatically and unconditionally released and the Subordinated Creditors shall (or shall cause their agent to) promptly execute and deliver to the Trustee such termination statements and releases as the Trustee shall request to effect the release of the liens and security interests of the Subordinated Creditors in such Collateral. In furtherance of the foregoing, the Subordinated Creditors hereby irrevocably appoint the Trustee their attorney-in-fact, with full authority in the place and stead of the Subordinated Creditors and in the name of the Subordinated Creditors or otherwise, to execute and deliver any document or instrument which the Subordinated Creditors may be required to deliver pursuant to this subsection 2.6 and which the Subordinated Creditors do not deliver to the Trustee within a reasonable period of time following written request therefor. The Trustee and the Noteholders shall have the exclusive right to enforce rights, exercise remedies and make determinations regarding the release, disposition, or restrictions with respect to the Collateral without any consultation with or the consent of any Subordinated Creditor or agent thereof. In exercising rights and remedies with respect to the Collateral, the Trustee and the Noteholders may enforce the provisions of the Senior Debt Documents and exercise remedies thereunder, all in such order and in such manner as they may determine in the exercise of their sole discretion. Such exercise and enforcement shall include the rights of an agent appointed by them to sell or otherwise dispose of Collateral upon foreclosure, to incur reasonable expenses in connection with such sale or disposition, and to exercise all the rights and remedies of a secured creditor under the Uniform Commercial Code of any applicable jurisdiction and of a secured creditor under Bankruptcy Laws of any applicable jurisdiction. Each Subordinated Creditor agrees that, it will not take or receive any Collateral or any proceeds of Collateral in connection with the exercise of any right or remedy with respect to any Collateral prior to the payment in full in cash of all Senior Debt. The Trustee, the Noteholders and the Subordinated Creditors agree not to take any action or vote in a manner inconsistent with this Agreement.

2.7 Sale, Transfer or other Disposition of Subordinated Debt.

(a) The Subordinated Creditors shall not sell, assign, pledge, dispose of or otherwise transfer all or any portion of the Subordinated Debt or any Subordinated Debt Document: (i) without giving written notice of such action to the Trustee, (ii) unless, prior to the consummation of any such action, the transferee thereof shall execute and deliver to the Trustee an agreement substantially identical to this Agreement, providing for the continued subordination of the Subordinated Debt to the Senior Debt as provided herein and for the continued effectiveness of all of the rights of the Trustee and Noteholders arising under this Agreement and (iii) unless, following the consummation of any such action, there shall be either (A) no more than five unaffiliated holders of the Subordinated Debt or (B) one Person acting as agent for all holders of the Subordinated Debt pursuant to documentation reasonably satisfactory to the Trustee such that any Payment Blockage Notices and other notices and communications to be delivered to the Subordinated Creditors hereunder and any consents required of the Subordinated Creditors shall be made to or obtained from such agent and shall be binding on the Subordinated Creditors as if directly obtained from the Subordinated Creditors.

- 9 -

(b) Notwithstanding the failure of any transferee to execute or deliver an agreement substantially identical to this Agreement, the subordination effected hereby shall survive any sale, assignment, pledge, disposition or other transfer of all or any portion of the Subordinated Debt, and the terms of this Agreement shall be binding upon the successors and assigns of the Subordinated Creditors, as provided in Section 9 hereof.

2.8 Legends. Until the termination of this Agreement in accordance with Section 15 hereof, the Subordinated Creditors will cause to be clearly, conspicuously and prominently inserted on the face of any notes issued pursuant to the Sponsor Facility and any other Subordinated Debt Document executed or delivered on or after the date hereof, as well as any renewals or replacements thereof, the following legend:

“This instrument and the rights and obligations evidenced hereby are subordinate in the manner and to the extent set forth in that certain Subordination and Intercreditor Agreement dated as of May 17, 2010 among the lenders party thereto, The Bank of New York Mellon Trust Company, N.A., American Petroleum Tankers Parent LLC (the “Company”), AP Tankers Co.

2.9 Insurance Proceeds. Prior to the payment in full in cash of all Senior Debt and subject to the rights of the Credit Parties under the Senior Debt Documents (i) the Trustee and the Noteholders shall have the sole and exclusive right to adjust settlement for any insurance policy covering the Collateral in the event of any loss thereunder and to approve any award granted in any condemnation or similar proceeding (or any deed in lieu of condemnation) affecting the Collateral and (ii) all proceeds of any such policy and any such award (or any payments with respect to a deed in lieu of condemnation) if in respect to the Collateral shall be paid over to the Trustee for application (in accordance with the Senior Debt Documents ) to the payment of the Senior Debt then remaining unpaid, until all of the Senior Debt is paid in full.

3. Modifications.

3.1 Modifications to Senior Debt Documents. The Trustee and the Noteholders may at any time and from time to time without the consent of or notice to the Subordinated Creditors, without incurring liability to the Subordinated Creditors and without impairing or releasing the obligations of the Subordinated Creditors under this Agreement, change the manner or place of payment or extend the time of payment of or renew or alter any of the terms of the Senior Debt, or amend in any manner any agreement, note, guarantee or other instrument evidencing or securing or otherwise relating to the Senior Debt in accordance with the Senior Debt Documents.

3.2 Modifications to Subordinated Debt Documents. Until the Senior Debt has been paid in full in cash and any and all amounts due on or in respect of Obligations under the Senior Debt Documents have terminated, and notwithstanding anything to the contrary contained in the Subordinated Debt Documents, the Subordinated Creditors shall not, without the

- 10 -

prior written consent of the Trustee, agree to any amendment, modification or supplement to the Subordinated Debt Documents the effect of which is to (a) shorten the maturity thereof, (b) provide for any cash interest or amortization payments thereon, (c) take any liens or security interests in any assets of any Issuer unless such assets are subject to the Trustee’s security interest and lien and such security interest and lien have the benefit of the priority established in Section 2.6 hereof or (d) otherwise augment or improve the rights, remedies or recourse of the Subordinated Creditors thereunder vis-à-vis any Credit Party or Noteholder.

4. Representations and Warranties of the Subordinated Creditors and the holders of Senior Debt.

The Trustee hereby represents and warrants to the Subordinated Trustee and the Subordinated Creditors that as of the date hereof: (a) the Trustee has the power and authority under the Indenture to enter into, execute, deliver and carry out the terms of this Agreement, all of which have been duly authorized by all proper and necessary action; (b) the execution of this Agreement by the Trustee will not violate or conflict with the organizational documents of the Trustee, any material agreement binding upon the Trustee or any law, regulation or order or require any consent or approval which has not been obtained; (c) this Agreement is the legal, valid and binding obligation of the Trustee, enforceable against the Trustee, in its role as Trustee under the Indenture, in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by equitable principles; (d) the holders of Senior Debt are the sole owners, beneficially and of record, of the Senior Debt Documents and the Senior Debt; and (e) pursuant to Section 13.15 of the Indenture, the holders of Senior Debt are bound hereby.

Subject to the payment in full in cash of all Senior Debt under the Senior Debt Documents, the Subordinated Creditors shall be subrogated to the rights of the Trustee and Noteholders to receive Distributions with respect to the Senior Debt until the Subordinated Debt is paid in full. The Subordinated Creditors agree that in the event that all or any part of a payment made with respect to the Senior Debt is recovered from the holders of the Senior Debt in a Proceeding or otherwise, any Distribution received by the Subordinated

- 11 -

Creditors with respect to the Subordinated Debt at any time after the date of the payment that is so recovered, whether pursuant to the right of subrogation provided for in this Agreement or otherwise, shall be deemed to have been received by the Subordinated Creditors in trust as property of the holders of the Senior Debt and the Subordinated Creditors shall forthwith deliver the same to the Trustee for the benefit of the Noteholders for application to the Senior Debt until the Senior Debt is paid in full. A Distribution made pursuant to this Agreement to the Trustee or Noteholders which otherwise would have been made to the Subordinated Creditors is not, as among the Credit Parties and the Subordinated Creditors, a payment by the Credit Parties to or on account of the Senior Debt.

Any modification or waiver of any provision of this Agreement, or any consent to any departure by any party from the terms hereof, shall not be effective in any event unless the same is in writing and signed by the Trustee, the Subordinated Creditors and each Credit Party and then such modification, waiver or consent shall be effective only in the specific instance and for the specific purpose given.
