Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

As previously disclosed, Westway Group, Inc., a Delaware corporation (the “Company”), Bishop Infrastructure III Acquisition Company, Inc., a Delaware corporation (the “Purchaser”), and Bishop Infrastructure II Acquisition Company, Inc., a Delaware corporation (the “Parent”) entered into an Agreement and Plan of Merger, dated as of December 20, 2012 (the “Merger Agreement”). Pursuant to the Merger Agreement, and upon the terms and conditions thereof, the Purchaser agreed to accept for payment in cash:

other than any Shares held by the Company as treasury stock or otherwise, in each case, net to the seller thereof in cash, without interest thereon and less any applicable withholding taxes, upon the terms and subject to the conditions set forth in the offer to purchase attached as an exhibit to the Tender Offer Statement on Schedule TO filed by the Purchaser, the Parent and EQT Infrastructure II Limited Partnership, a limited partnership registered in England and Wales (the “Guarantor”), with the Securities and Exchange Commission (the “SEC”) on December 31, 2012 (together with all amendments thereto, the “Offer to Purchase”) and the related letter of transmittal (the “Letter of Transmittal,” and together with the Offer to Purchase, the “Offer”).

Pursuant to a certificate of ownership and merger filed with the Delaware Secretary of State on January 31, 2013 with effectiveness on February 1, 2013, the Purchaser was merged with and into the Company (the “Merger”) in accordance with the “short-form” merger procedures available under section 253 of the General Corporation Law of the State of Delaware (“DGCL”). As a result of the Offer and the Merger, the Company no longer fulfills the numerical listing requirements of The NASDAQ Stock Market LLC (“NASDAQ”). Accordingly, on February 1, 2013, the Company notified NASDAQ of its intent to remove the shares of Class A Common Stock from listing on NASDAQ and requested that NASDAQ file a delisting application with the SEC under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) on Form 25 to delist and deregister such shares. The Company will file with the SEC a certification on Form 15 under the Exchange Act to request the deregistration of the Class A Common Stock and the suspension of the Company’s reporting obligations under Sections 13 and 15(d) of the Exchange Act with respect to the Class A Common Stock.

Item 3.03 Material Modification to Rights of Security Holders

At the effective time of the Merger (the “Effective Time”), each remaining issued and outstanding Security not tendered in the Offer (other than Securities held by the Parent, the Purchaser or the Company (as treasury stock or otherwise) or any of their respective direct or indirect wholly-owned subsidiaries, and Securities for which appraisal rights were properly demanded and perfected in accordance with the DGCL was, by virtue of the Merger and without any action on the part of the holders thereof, converted into the right to receive the applicable Offer Price in cash, without interest thereon and less any required withholding taxes, subject to any appraisal rights available to the holders of such Securities under section 263 of the DGCL.

Item 5.01 Changes in Control of Registrant

The Offer and related withdrawal rights expired at 12:00 midnight (New York City time) on Wednesday, January 30, 2013 (the “Expiration Time”). According to Continental Stock Transfer and Trust Company, as depositary for the Offer, as at the Expiration Time: (i) 12,543,420 shares of Class A Common Stock, (ii) 13,652,763 shares of Class B Common Stock, (iii) 33,321,892 shares of Preferred Stock and (iv) 3,476,189 Warrant Shares had been validly tendered pursuant to the Offer and not properly withdrawn. In accordance with the terms of the Offer, the Purchaser accepted for payment all Securities validly tendered pursuant to the Offer and payment for such Securities will be made promptly in accordance with the terms of the Offer. Immediately after consummation of the Offer, the Purchaser held approximately 93% of the Company’s outstanding shares of Common Stock, 100% of the Company’s Preferred Stock and 100% of the Warrants.

Prior to the consummation of the Offer: (i) Agman Louisiana, Inc. (“Agman”), a subsidiary of ED&F Man Holdings Limited, held approximately 72% of the Company’s outstanding shares of Common Stock, (ii) Mr. Francis P. Jenkins, Jr., a director of the Company, held approximately 6% of the Company’s outstanding shares of Common

Stock, and (iii) Mr. John E. Toffolon, Jr., director of the Company, held approximately 1% of the Company’s outstanding shares of Common Stock. All of the Securities held by each of Agman, Mr. Jenkins and Mr. Toffolon were validly tendered and accepted for payment pursuant to the Offer.

As a result of the purchase of Shares pursuant to the Offer, the Parent and the Purchaser had sufficient voting power in the Company to effect a “short-form” merger under section 253 of the DGCL. The Purchaser was merged with and into the Company in accordance with section 253 of the DGCL, with the Company surviving as a wholly-owned subsidiary of the Parent. At the Effective Time, each remaining issued and outstanding Security not tendered in the Offer (other than Securities held by the Parent, the Purchaser or the Company (as treasury stock or otherwise) or any of their respective direct or indirect wholly-owned subsidiaries, and Securities for which appraisal rights are properly demanded and perfected in accordance with the DGCL) was, by virtue of the Merger and without any action on the part of the holders thereof, converted into the right to receive the applicable Offer Price in cash, without interest thereon and less any required withholding taxes.

Total consideration paid by the Purchaser for the Securities tendered in the Offer and for the Securities acquired pursuant to the Merger was approximately $421,000,000. The Parent, as the Purchaser’s direct parent company, provided the Purchaser with sufficient funding to purchase all Securities accepted for payment in the Offer and to acquire the remaining Securities in the Merger. The Parent obtained such funds from equity contributions from the Guarantor, and from existing cash reserves of the Company.

To the knowledge of the Company, there are no arrangements, including any pledge by any person of securities of the Company or the Parent, the operation of which may at a subsequent date result in a further change in control of the Company.
