Exhibit 10.4

Execution Version

LIMITED GUARANTEE

This Limited Guarantee is made by EQT Infrastructure II Limited Partnership, acting by its general partner EQT Infrastructure II GP B.V. (the General Partner), a limited partnership registered in England and Wales (Guarantor), in favor of Westway Group, Inc., a Delaware corporation (Guaranteed Party), as of December 20, 2012 (this Guarantee). Reference is hereby made to that certain Agreement and Plan of Merger, dated as of the date hereof (as amended, restated, supplemented or otherwise modified from time to time, the Merger Agreement), by and among the Bishop Infrastructure II Acquisition Company, Inc., a Delaware corporation (Parent), Bishop Infrastructure III Acquisition Company, Inc., a Delaware corporation and wholly-owned subsidiary of Parent (Merger Sub), and the Guaranteed Party, pursuant to which Merger Sub has agreed to (i) commence a tender offer for all of the outstanding Shares and all of the outstanding In-the-Money Warrants (the Offer), and (ii) if the Offer is completed on the terms and subject to the conditions set forth in the Merger Agreement, merge with and into the Guaranteed Party (the Merger), with the Guaranteed Party surviving the Merger as a wholly-owned subsidiary of Parent. Capitalized terms used herein and not otherwise defined herein shall have the meanings given to such terms in the Merger Agreement.

1. Guarantee; Related Covenant. This Guarantee is made to induce Guaranteed Party to enter into the Merger Agreement. Guarantor hereby absolutely, unconditionally and irrevocably guarantees, but only up to the Cap (as defined below), as primary obligor and not merely as surety, the due and punctual payment, performance and discharge of the obligations of Parent to pay or perform, or to provide adequate funds for the payment to cause Merger Sub to pay, perform and discharge Parent’s and Merger Sub’s payment obligations under the Merger Agreement (the Obligations); provided that in no event shall Guarantor’s aggregate liability under this Guarantee exceed $419,300,000 (the Cap). In furtherance of the foregoing, Guarantor acknowledges that its liability under this Guarantee shall extend to the full amount of the Obligations, subject to the Cap, and that Guaranteed Party may, in its sole discretion, bring and prosecute a separate action or actions against Guarantor for the full amount of the Obligations up to the Cap, regardless of whether action is brought against the Parent or Merger Sub or whether the Parent or Merger Sub are joined in any such action. Notwithstanding anything in this Guarantee to the contrary, in no event shall the Guarantor’s aggregate liability under this Guarantee exceed the Cap, and Guaranteed Party agrees that it shall not assert any claim, directly or indirectly, that Guarantor is liable under this Guarantee for any amount in excess of the Cap. In order to provide Parent and Merger Sub with the amounts necessary to pay (i) the amount that Merger Sub is obligated to pay in respect of Shares and In-the-Money Warrants tendered pursuant to the Offer, pursuant to the terms, and subject to the conditions, of the Merger Agreement, (ii) the Merger Consideration, pursuant to the terms, and subject to the conditions, of the Merger Agreement, and (iii) Parent’s and Merger Sub’s fees and expenses associated with the transactions under by the Merger Agreement, Guarantor hereby commits to, at the Offer Closing and on the Effective Date (as applicable), purchase (or cause to be purchased) equity securities from Parent in an aggregate amount not to exceed the Cap.

2. Nature of Guarantee. Guarantor hereby agrees that the Obligations shall not be deemed to have been released, dismissed, impaired, reduced, discharged, paid, observed or performed or affected as the result of the bankruptcy, insolvency, disability, dissolution, receivership, reorganization or lack of corporate or other power of Parent or Merger Sub, and Guarantor’s liability in respect thereof shall continue and not be discharged, including, without limitation, the case in which any payment or performance thereof by Parent or Merger Sub is recovered from or paid over by or on behalf of the Guaranteed Party by reason of a fraudulent transfer by Parent or Merger Sub or as a preference in any bankruptcy of Parent or Merger Sub. Without limiting the foregoing, Guaranteed Party shall not be obligated to file any claim relating to the Obligations in the event that the Parent or Merger Sub becomes subject to a bankruptcy, reorganization or similar proceeding, and the failure of Guaranteed Party to so file shall not affect Guarantor’s obligations under this Guarantee. In the event that any payment to Guaranteed Party in respect of the Obligations is rescinded or must otherwise be returned in connection with the insolvency or bankruptcy of any of Parent or Merger Sub (including, without limitation, the rejection of the Merger Agreement in an insolvency or bankruptcy of any of Parent or Merger Sub, as the case may be), Guarantor shall remain liable under this Guarantee with respect to the Obligation as if such payment had not been made. This is an unconditional guarantee of payment and not of collectability. Notwithstanding any other provision of this Guarantee, Guaranteed Party hereby agrees that Guarantor may assert, as a defense to such payment or performance by Guarantor under this Guarantee, any rights, remedies, set-offs and defenses to such payment or performance that the Parent or Merger Sub could assert against Guaranteed Party under the terms of the Merger Agreement (other than any such rights, remedies, set-offs and defenses arising out of, due to, or as a result of, the insolvency or bankruptcy of any of Parent or Merger Sub (including, without limitation, the rejection of the Merger Agreement in an insolvency or bankruptcy of any of Parent or Merger Sub, as the case may be)).

3. Changes in Obligations.

(a) Subject to Section 8, Guarantor agrees that Guaranteed Party may, with Parent’s consent if such consent is required under the Merger Agreement, at any time and from time to time, without notice to or further consent of Guarantor, extend the time of payment of any Obligations, and may also make any agreement with Parent or Merger Sub for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any agreement between Guaranteed Party and Parent or Merger Sub without in any way impairing or affecting the Guarantor’s obligations under this Guarantee or affecting the validity or enforceability of this Guarantee. Guarantor agrees that the obligations of Guarantor under this Guarantee shall not be released or discharged, in whole or in part, or otherwise affected by (i) the failure or delay of Guaranteed Party to assert any claim or demand or to enforce any right or remedy against Guarantor, Parent or Merger Sub (or

Page 2

any of their respective permitted assignees) or any other Person; (ii) any change in time, place or manner of payment of any Obligation or any rescission, waiver, compromise, consolidation or other amendment to or modification of any of the terms or provisions of the Merger Agreement made in accordance with the terms thereof or any other agreement evidencing, securing or otherwise executed in connection with any of the Obligations; (iii) the addition, substitution or release of either of Parent of Merger Sub or either of their permitted assignees or any other Person; (iv) any change in the corporate existence, structure or ownership of either of Parent or Merger Sub (or any of their permitted assignees) or any other Person; (v) any insolvency, bankruptcy, reorganization or other similar proceeding affecting either of Parent or Merger Sub (or any of their respective permitted assignees) or any other Person; (vi) the existence of any claim, set-off or other right which Guarantor may have at any time against either of Parent or Merger Sub or Guaranteed Party or any of their Affiliates, whether in connection with the Obligation or otherwise (other than those described in the last sentence of Section 2 above); (vii) the adequacy of any other means Guaranteed Party may have of obtaining payment of any Obligation other than from Parent or Merger Sub; (viii) the value, genuineness, validity, illegality or enforceability of the payment of the Merger Consideration or the amount that Merger Sub is obligated to pay in respect of the Shares and In-the-Money Warrants tendered pursuant to the Offer; or (ix) any discharge of Guarantor as a matter of applicable law (other than as a result of, and to the extent of, payment of the Obligations in accordance with their terms or otherwise pursuant to the terms of this Guarantee). Notwithstanding anything to the contrary contained in this Guarantee, Guaranteed Party hereby agrees that to the extent that either Parent or Merger Sub is relieved of its obligations and liabilities under the Merger Agreement (other than due to, in connection with, or as a result of, the insolvency or bankruptcy of either of Parent or Merger Sub (including, without limitation, the rejection of the Merger Agreement in an insolvency or bankruptcy of either of Parent or Merger Sub)), Guarantor shall be similarly relieved of any of the obligations under this Guarantee. Guaranteed Party agrees that any payment made by any of Parent or Merger Sub with respect to the Obligations in accordance with the Merger Agreement shall reduce Guarantor’s obligation under this Guarantee by the full amount of such payment.

(b) To the fullest extent permitted by Law, Guarantor hereby expressly waives any and all rights or defenses arising by reason of any Law which would otherwise require any election of remedies by Guaranteed Party. Without limiting the express terms of this Guarantee, Guarantor waives promptness, diligence, notice of the acceptance of this Guarantee and of any Obligation, presentment, demand for payment, notice of non-performance, default, dishonor and protest, notice of the incurrence of any Obligation and all other notices of any kind, all defenses which may be available by virtue of any valuation, stay, moratorium Law or other similar Law now or hereafter in effect, any right to require the marshalling of assets of Parent, Merger Sub or any other Person liable with respect to any Obligation, and all suretyship defenses generally. Guarantor hereby expressly waives any right to require Guaranteed Party to proceed against Parent or Merger Sub or pursue any other remedy in the Guaranteed Party’s power whatsoever. Guarantor acknowledges that it will receive substantial direct and

Page 3

indirect benefits from the transactions contemplated by the Merger Agreement and that the waivers, agreements and other terms set forth in this Guarantee are knowingly made in contemplation of such benefits and that if any of such waivers, agreements and other terms are determined contrary to any applicable Law or public policy, such waivers, agreements and other terms shall be effective only to the maximum extent permitted by applicable Law. Notwithstanding the foregoing, neither this Section 3(b) nor Section 3(a) shall be construed as a waiver of any defense by Parent or Merger Sub (or in the case of Section 3(a), an agreement not to release or discharge obligations) in the event of (i) actual fraud by Guaranteed Party or any of its Affiliates, (ii) defenses to the payment of the Obligations that are available to Parent or Merger Sub under the Merger Agreement or (iii) breach by Guaranteed Party of this Guarantee or the Merger Agreement, each of which are retained by Guarantor.

(c) At any time prior to payment in full of the Obligations, Guarantor hereby unconditionally and irrevocably waives, and agrees not to exercise, any rights that it may now have or hereafter acquire against Parent, Merger Sub or any other Person liable with respect to any Obligations that arise from the existence, payment, performance, or enforcement of Guarantor’s obligations under or in respect of this Guarantee or any other agreement in connection therewith, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Guaranteed Party against Parent, Merger Sub or such other Person, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from Parent, Merger Sub or such other Person, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, in each case unless all amounts payable under this Guarantee shall have been paid in full in cash. If any amount shall be paid to Guarantor in violation of the immediately preceding sentence at any time prior to the payment in full in cash of all amounts payable under this Guarantee, such amount shall be received and held in trust for the benefit of Guaranteed Party, shall be segregated from other property and funds of Guarantor and shall forthwith be paid or delivered to Guaranteed Party in the same form as so received (with any necessary endorsement or assignment) to be credited and applied to the amounts payable under this Guarantee, in accordance with the terms of the Merger Agreement, whether matured or unmatured, or to be held as collateral for the amounts payable under this Guarantee thereafter arising.

(d) Guarantor hereby covenants and agrees that it shall not institute, directly or indirectly, and shall cause its Affiliates not to institute, directly or indirectly, any litigation or other proceeding asserting that this Guarantee is illegal, invalid or unenforceable in accordance with its terms.

(e) Notwithstanding anything to the contrary contained in this Guarantee, Guarantor shall have the right to cause any other Person to satisfy its payment obligations to Guaranteed Party under this Guarantee.

(f) Guaranteed Party hereby covenants and agrees that it shall not assert, and shall cause its Affiliates not to assert, in any litigation or other proceeding: (i) that Section 1 of this Guarantee limiting Guarantor’s aggregate liability to the Cap is illegal, invalid or unenforceable in whole or in part, (ii) the Guarantor is liable in excess of the Cap, or (iii) any theory of liability whatsoever against (A) Guarantor, Parent or Merger Sub; (B) any former, current or future direct or indirect director, officer, employee, agent (including of the General Partner) or Affiliate of Guarantor (other than Parent or Merger Sub), Parent or Merger Sub, (C) any former, current or future direct or indirect holder of any equity interests or securities of Guarantor, Parent or Merger Sub (whether such holder is a limited or general partner, member, stockholder or otherwise), (D) any former, current or future assignee of Guarantor, Parent or Merger Sub or (E) any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder, affiliate, controlling person, representative or assignee of any of the foregoing (each such person or entity in clauses (B) through (E), a Related Person) under or in connection with this Guarantee or the Merger Agreement and any transactions contemplated thereby or instrument delivered therewith other than a claim (x) against Guarantor for payment under this Guarantee (as limited by its terms, including the provisions of Section 1 of this Guarantee) or (y) against Parent or Merger Sub pursuant to the Merger Agreement.

4. No Waiver; Cumulative Rights. No failure on the part of Guaranteed Party to exercise, and no delay in exercising, any right, remedy or power under this Guarantee shall operate as a waiver thereof, nor shall any single or partial exercise by Guaranteed Party of any right, remedy or power under this Guarantee, under the Merger Agreement or otherwise, preclude any other or future exercise of any right, remedy or power under this Guarantee. Each and every right, remedy and power hereby granted to Guaranteed Party or allowed Guaranteed Party by law, in equity or by other agreement shall be cumulative and not exclusive of any other, and may be exercised by Guaranteed Party at any time or from time to time.

5. Representations and Warranties.
