Item 3. Source and Amount of Funds or Other Consideration

The Class A Securities were acquired with $159,708,059.17 of working capital set aside for the general purpose of investing.

Item 4. Purpose of Transaction.

The Reporting Persons acquired the Class A Securities for investment purposes.

OSG entered into an Equity Commitment Agreement, dated as of May 2, 2014, as amended by Amendment Number 1 thereto, dated as of May 20, 2014, and as further amended by Amendment Number 2 thereto, dated as of May 23, 2014 (as so amended, the “ECA”), with certain of the Reporting Persons and certain other parties (each referred to therein as a “Commitment Party” and collectively as the “Commitment Parties”). The ECA was terminated on August 5, 2014 in connection with the consummation of the Plan (as defined below).

Pursuant to the ECA, OSG agreed, in connection with the consummation of a chapter 11 plan of reorganization (the “Plan”), to issue and distribute its common stock and/or warrants to any person who held shares of OSG’s common stock on the date of the ECA and who elected to exercise subscription rights in accordance with procedures approved by the Bankruptcy Court (the “Rights Offering Procedures”). Pursuant to the ECA, each Commitment Party, severally and not jointly, agreed with OSG to back-stop, or cause its designees under the ECA to back-stop, certain securities underlying the subscription rights that were not exercised in accordance with the Rights Offering Procedures. In addition, each Commitment Party agreed to purchase a portion of a further additional number of Class A Securities offered by OSG to such Commitment Party. As consideration for the foregoing back-stop commitment, OSG was required to pay a certain premium in the form of Class A Securities to each Commitment Party. Whether issued, upon the valid exercise of the subscription rights or otherwise in accordance with the terms of the ECA, Class A Securities were offered, sold, issued and distributed without registration under the Securities Act of 1933 on August 5, 2014. The total number of securities in the form of Class A Common Stock and/or Warrants was determined as set forth in the Rights Offering Procedures.

Pursuant to the ECA, on August 5, 2014, Nautical purchased and received 56,775,644 shares of Class A Common Stock for an aggregate purchase price of $157,749,902.17, and AAI purchased and received 175,054 shares of Class A Common Stock and 524,294 Warrants for an aggregate purchase price of $1,958,157.

On May 2, 2014, OSG entered into a Registration Rights Agreement, as amended by Amendment Number 1 thereto, dated as of May 23, 2014 (as so amended, the “Registration Rights Agreement”), with each Commitment Party setting forth, among other things, registration rights of each Commitment Party and, potentially, certain other holders of Class A Securities. Pursuant to the Registration Rights Agreement, OSG is required to register, on a registration statement to be filed with the Securities and Exchange Commission, the resale of certain Class A Securities for the benefit of the Reporting Persons, the other Commitment Parties and potentially certain other shareholders.

The Reporting Persons acquired the Class A Securities over which they exercise beneficial ownership in the belief that the Class A Securities represent an attractive investment opportunity. Subject to the terms of the Registration Rights Agreement, the Reporting Persons from time to time may enter into discussions with directors and officers of the Issuer, other shareholders or third parties in connection with the Reporting Persons’ investment in the Issuer. Such discussions may include one or more members of management, the board, other stockholders of the Issuer and other persons to discuss the Issuer’s business, strategies and other matters related to the Issuer. These discussions may include reviewing various options available to the Issuer and/or making proposals for enhancing or maximizing shareholder value through various strategic alternatives, including changes to the capitalization, ownership structure, operations, or Certificate of Incorporation or Bylaws of the Issuer, or any strategic transaction or similar opportunities. Alternatively, the Reporting Persons may elect not to engage with directors or officers of the Issuer and maintain a passive investment in the Class A Securities. The Reporting Persons may also explore increasing their ownership position in the Issuer, through open market purchases, an acquisition of securities from other significant stockholders, or otherwise based on market conditions and other developments at the time.

CUSIP No. 69036R 103

The Reporting Persons intend to review their respective investment in the Issuer on a continuing basis and may from time to time and at any time in the future depending on various factors, including, without limitation, the outcome of any discussions referenced above, the Issuer’s financial position and strategic direction, actions taken by the board and/or management, price levels of the Issuer’s (or that of any of its affiliates) common stock and/or other instruments, other investment opportunities available to the Reporting Persons, conditions in the securities market and general economic and industry conditions, take such actions with respect to the investment in the Issuer as they deem appropriate, including: (i) acquiring additional common stock and/or other equity, debt, notes, other securities, or derivatives or other instruments that are based upon or relate to the value of the common stock of the Issuer and/or any of its affiliates (collectively, the “Securities”) in the open market or otherwise; (ii) disposing of any or all of their Securities in the open market or otherwise; (iii) engaging in any hedging or similar transactions with respect to the Securities; or (iv) proposing or considering one or more of the actions described in Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer.
