     This Amendment No. 4 to the Tender Offer Statement on Schedule TO (this “Amendment”), filed with the Securities and Exchange Commission (the “SEC”) on May 29, 2007, amends and supplements the Tender Offer Statement on Schedule TO filed on April 27, 2007 (as previously amended, the “Schedule TO”) by (i) Omaha, Inc., a corporation organized under the laws of the Republic of The Marshall Islands (the “Purchaser”) and a jointly owned subsidiary of Teekay Shipping Corporation (“Teekay”), through its wholly owned subsidiary Teekay Acquisition Holdings LLC (“Teekay Acquisition Holdings”), and A/S Dampskibsselskabet TORM (“TORM”), (ii) Teekay, (iii) Teekay Acquisition Holdings, and (iv) TORM. The Schedule TO relates to the offer by the Purchaser to purchase all outstanding shares of common stock, par value $0.50 per share (the “Common Stock”), including the associated preferred stock purchase rights issued pursuant to the Rights Agreement dated November 19, 1998, as amended, between the Company and American Stock Transfer and Trust Company, as Rights Agent thereunder (the “Rights” and, together with the shares of Common Stock, the “Shares”), of OMI Corporation, a corporation organized under the laws of the Republic of The Marshall Islands (the “Company”), at a purchase price of $29.25 per Share, net to the seller in cash, without interest thereon, less any required withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase dated April 27, 2007 (the “Offer to Purchase”) and the related Letter of Transmittal, copies of which are attached to the Schedule TO as Exhibits (a)(1)(i) and (a)(1)(ii), respectively (which, together with any amendments or supplements thereto, collectively constitute the “Offer”). Capitalized terms used and not defined herein shall have the meanings assigned such terms in the Offer to Purchase.

     The information in the Offer to Purchase and the related Letter of Transmittal is incorporated into this Amendment by reference to all of the applicable items in the Schedule TO, except that such information is hereby amended and supplemented to the extent specifically provided herein.

Items 8 and 11.     Interest in Securities of Subject Company; Additional Information

     Items 8 and 11 of the Schedule TO are hereby amended and supplemented by adding the following text thereto:

     “The initial period of the Offer expired at 5:00 p.m., New York City time, on Friday, May 25, 2007. Pursuant to the Offer, based on a preliminary report from Citibank, N.A., the depositary for the Offer, as of 5:00 p.m., New York City time, on Friday, May 25, 2007, a total of 49,762,507 Shares were validly tendered and not withdrawn (including 2,272,284 Shares tendered pursuant to the guaranteed delivery procedures set forth in the Offer to Purchase). Parents and Purchaser have been informed by the Company’s transfer agent that the number of issued and outstanding Shares as of May 25, 2007, the date of the expiration of the Offer, was 61,984,900. All such validly tendered Shares were accepted for payment, which shall be made promptly in accordance with the terms of the Offer. On the date Purchaser pays for the validly tendered Shares, 2,415,610 restricted Shares will be cancelled in accordance with the terms of the Transaction Agreement, which, after accounting for the tendered Shares, will result in Purchaser owning 83.5% of the outstanding Shares. The percentage of Shares that were validly tendered and not withdrawn pursuant to the Offer (including the Shares tendered pursuant to the guaranteed delivery procedures) is approximately 80.3% of all outstanding Shares as of the date of the expiration of the Offer.

     On May 26, 2007, Teekay and TORM announced the results of the Offer and commencement of a subsequent offering period for all remaining untendered Shares expiring at 5:00 p.m., New York City time, on Tuesday, June 5, 2007, unless further extended. During the subsequent offering period, holders of Shares who did not previously tender their Shares into the Offer may do so. All Shares validly tendered during the subsequent offering period will be immediately accepted. Holders of Shares who so tender will promptly receive the same purchase price to be paid pursuant to the Offer of $29.25 per Share in cash, without interest thereon, less any required withholding taxes, in accordance with the terms of the Offer. The procedures for accepting the Offer and tendering Shares during the subsequent offering period are the same as those described for the Offer in the Offer to Purchase except that (i) the guaranteed delivery procedures may not be used during the subsequent offering period and (ii) Shares tendered during the subsequent offering period may not be withdrawn.

     The full text of the press release issued by Teekay and TORM and announcing the results of the tender offer and commencement of the subsequent offering period is attached hereto as Exhibit (a)(5)(v) and is incorporated herein by reference.”
