REPRESENTATIONS AND WARRANTIES OF THE PURCHASER

     The Purchaser represents and warrants to Buckeye that:

          Section 4.1 Existence. The Purchaser is duly organized and validly existing and in good standing under the Laws of its jurisdiction of organization, with all requisite power and authority to own, lease, use and operate its Properties and to conduct its business as currently conducted.

          Section 4.2 Authorization, Enforceability. The Purchaser has all necessary corporate power and authority to execute, deliver and perform its obligations under this Agreement and the Registration Rights Agreement and to consummate the transactions contemplated thereby, and the execution, delivery and performance by the Purchaser of this Agreement and the Registration Rights Agreement has been duly authorized by all necessary action on the part of the Purchaser; and this Agreement and the Registration Rights Agreement constitute the legal, valid and binding obligations of the Purchaser, enforceable in accordance with their terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent transfer and similar laws affecting creditors’ rights generally or by general principles of equity, including principles of commercial reasonableness, fair dealing and good faith.

          Section 4.3 No Breach. The execution, delivery and performance of this Agreement and the Registration Rights Agreement by the Purchaser and the consummation by the Purchaser of the transactions contemplated hereby and thereby will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material agreement to which the Purchaser is a party or by which the Purchaser is bound or to which any of the property or assets of the Purchaser is subject, (b) conflict with or result in any violation of the provisions of the organizational documents of the Purchaser, or (c) violate any statute, order, rule or regulation of any court or governmental agency or body having jurisdiction over the Purchaser or the property or assets of the Purchaser, except in the cases of clauses (a) and (c), for such conflicts, breaches, violations or defaults as would not prevent the consummation of the transactions contemplated by this Agreement and the Registration Rights Agreement.

          Section 4.4 Certain Fees. No fees or commissions are or will be payable by the Purchaser to brokers, finders, or investment bankers with respect to the purchase of any of the Consideration Units or the consummation of the transaction contemplated by this Agreement. The Purchaser agrees that it will indemnify and hold harmless Buckeye from and against any and all claims, demands, or liabilities for broker’s, finder’s, placement, or other similar fees or commissions incurred by the Purchaser in connection with the purchase of the Consideration Units or the consummation of the transactions contemplated by this Agreement.

          Section 4.5 Investment. The Consideration Units are being acquired for the Purchaser’s own account and with no intention of distributing the Consideration Units or any part thereof, and the Purchaser has no present intention of selling or granting any participation in or otherwise distributing the same in any transaction in violation of the securities laws of the United States or any state, without prejudice, however, to the Purchaser’s right at all times to sell or otherwise dispose of all or any part of the Consideration Units under a registration statement under the Securities Act and applicable state securities laws or under an exemption from such registration available thereunder (including, without limitation, if available, Rule 144 promulgated thereunder). If the Purchaser should in the future decide to dispose of any of the Consideration Units, the Purchaser understands and agrees (a) that it may do so only in compliance with the Securities Act and applicable state securities law, as then in effect, including a sale contemplated by any registration statement pursuant to which such securities are being offered, or pursuant to an exemption from the Securities Act, and (b) that stop-transfer instructions to that effect will be in effect with respect to such securities.

          Section 4.6 Nature of Purchaser. The Purchaser represents and warrants to, and covenants and agrees with, Buckeye that, (a) it is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated by the Commission pursuant to the Securities Act and (b) by reason of its business and financial experience it has such knowledge, sophistication and experience in making similar investments and in business and financial matters generally so as to be capable of evaluating the merits and risks of the prospective investment in the Consideration Units, is able to bear the economic risk of such investment and, at the present time, would be able to afford a complete loss of such investment.

          Section 4.7 Restricted Securities. The Purchaser understands that the Consideration Units are characterized as “restricted securities” under the federal securities Laws inasmuch as they are being acquired from Buckeye in a transaction not involving a public offering and that under such Laws and applicable regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, the Purchaser represents that it is knowledgeable with respect to Rule 144 of the Commission promulgated under the Securities Act.

          Section 4.8 Legend. The Purchaser understands that the books and records of the transfer agents for the Consideration Units will include, as a restrictive notation, the legend required by the Partnership Agreement as well as the following legend: “These securities have not been registered under the Securities Act of 1933, as amended (the “Securities Act”). These securities may not be sold or offered for sale except pursuant to an effective registration statement under the Securities Act or pursuant to an exemption from registration thereunder, in each case in accordance with all applicable securities laws of the states or other jurisdictions, and in the case of a transaction exempt from registration, such securities may only be transferred if the transfer agent for such securities has received documentation satisfactory to it that such transaction does not require registration under the Securities Act.”

INDEMNIFICATION

          Section 6.1 Indemnification by Buckeye. Buckeye agrees to indemnify the Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of Buckeye contained herein, provided that such claim for indemnification relating to a breach of the representations or warranties is made prior to the expiration of such representations or warranties; and provided further, that no Purchaser Related Party shall be entitled to recover special, consequential (including lost profits or diminution in value) or punitive damages. Notwithstanding anything to the contrary, consequential damages shall not be deemed to include diminution in value of the Consideration Units, which is specifically included in damages covered by Purchaser Related Parties’ indemnification.

          Section 6.2 Indemnification by the Purchaser. Vopak Parent agrees to indemnify Buckeye, the General Partner and their respective Representatives (collectively, “Buckeye Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of the Purchaser contained herein, provided that such claim for indemnification relating to a breach of the representations and warranties is made prior to the expiration of such representations and warranties; and provided further, that no Buckeye Related Party shall be entitled to recover special, consequential (including lost profits or diminution in value) or punitive damages.

          Section 6.3 Indemnification Procedure. Promptly after any Buckeye Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall

state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party.

Exhibit A — Form of Opinion of Vinson & Elkins L.L.P.

Capitalized terms used but not defined herein have the meanings assigned to such terms in the Unit Purchase Agreement (the “Purchase Agreement”). Buckeye shall furnish to the Purchaser at the Closing an opinion of Vinson & Elkins L.L.P., counsel for Buckeye, addressed to the Purchaser and dated the Closing Date in form satisfactory to the Purchaser, stating that:

     1. Each of Buckeye and the General Partner is a validly existing limited partnership or limited liability company, respectively, in good standing under the laws of the State of Delaware. Buckeye has all requisite limited partnership power and authority under the laws of the State of Delaware necessary (a) to own its properties and carry on its business as its business is now being conducted as described in the Buckeye SEC Documents, (b) to enter into and perform its obligations under the Operative Documents and (c) to offer, issue and sell the Consideration Units as provided in the Purchase Agreement.

     2. To our knowledge, except as described in the Buckeye SEC Documents filed prior to the date of the Purchase Agreement, no options, warrants or other rights to purchase, agreements or other obligations to issue, or rights to convert any obligations into or exchange any securities for, partnership securities or ownership interests in Buckeye are outstanding.

     3. The Consideration Units to be issued and sold to the Purchaser by Buckeye pursuant to the Purchase Agreement and the limited partner interests represented thereby have been duly authorized in accordance with the Partnership Agreement and, when issued and delivered to the Purchaser against payment therefor in accordance with the terms of the Purchase Agreement, will be validly issued in accordance with the terms of the Partnership Agreement, fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act (the “Delaware LP Act”)).

     4. The LP Units issuable upon conversion of the Consideration Units that are Class B Units, the issuance of Class B Units as a distribution in kind in lieu of cash distributions on the Class B Units and the issuance of any LP Units in lieu of cash as liquidated damages under the Registration Rights Agreement and, in each case, the limited partner interests represented thereby, upon issuance in accordance with the terms of the Class B Units as reflected in the Partnership Agreement Amendment or the Registration Rights Agreement, as applicable, have been duly authorized in accordance with the Partnership Agreement and will be validly issued, fully paid (to the extent required by applicable law and the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the Delaware LP Act).

     5. No authorization, consent, approval, waiver, license, qualification, filing, declaration or registration with any Governmental Authority is required for the issuance and sale by Buckeye of the Consideration Units, the execution, delivery and performance by Buckeye of the Operative Documents or the consummation of the transactions contemplated thereby (including issuance of LP Units upon conversion of the Consideration Units that are Class B Units, the issuance of any Class B Units as a distribution in kind in lieu of cash distributions on

Exhibit A to Unit Purchase Agreement
(Vopak)

the Class B Units and the issuance of any LP Units in lieu of cash as liquidated damages under the Registration Rights Agreement), except for (A) those that have been obtained or as may be required under state securities or “Blue Sky” laws, as to which we do not express any opinion and (B) the approvals required by the Commission in connection with Buckeye’s obligations under the Registration Rights Agreement.

     6. Assuming the accuracy of the representations and warranties of the Purchaser and Buckeye contained in the Purchase Agreement, the offer, issuance and sale of the Consideration Units by Buckeye to the Purchaser solely in the manner contemplated by the Purchase Agreement are exempt from the registration requirements of the Securities Act of 1933, as amended; provided that we express no opinion as to any subsequent sale.

     7. The holders of outstanding LP Units are not entitled to statutory, preemptive or, to our knowledge, other similar contractual rights to subscribe for the Consideration Units.

     8. Buckeye is not, and after giving effect to the use of proceeds from the sale of the Consideration Units pursuant to the Purchase Agreement will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

     9. None of the offering, issuance and sale by Buckeye of the Consideration Units, the execution, delivery and performance of the Operative Documents by Buckeye or the consummation of the transactions contemplated thereby (including issuance of LP Units upon conversion of the Consideration Units that are Class B Units, the issuance of any Class B Units as a distribution in kind in lieu of cash distributions on the Class B Units and the issuance of any LP Units in lieu of cash as liquidated damages under the Registration Rights Agreement) conflicts or will conflict with, or results or will result in a breach or violation of (A) the Partnership Agreement, (B) any agreement filed or incorporated by reference as an exhibit to Buckeye’s Annual Report on Form 10-K for the period ended December 31, 2009 or Buckeye’s Quarterly Reports on Forms 10-Q for the quarters ended March 31, 2010, June 30, 2010 and September 30, 2010 or (C) the Delaware LP Act, the Delaware Limited Liability Company Act (the “Delaware LLC Act”) or U.S. federal law, which in the case of clause (B) or (C) would be reasonably expected to have a Material Adverse Effect; provided, however, that we express no opinion pursuant to this paragraph 9 with respect to federal or state securities or anti-fraud statutes, rules or regulations.

     10. Each of Operative Documents has been duly authorized and validly executed and delivered by Buckeye and the General Partner, as the case may be, and constitutes a valid and binding obligation of Buckeye and the General Partner, as the case may be, enforceable against Buckeye and the General Partner, as the case may be, in accordance with its terms, except as the enforceability thereof may be limited by (A) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws from time to time in effect affecting creditors’ rights and remedies generally and by general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law) and (B) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.
