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.

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.

In this connection, the Purchaser represents that it is knowledgeable with respect to Rule 144 of the Commission promulgated under the Securities Act.

The Purchaser understands that the certificates evidencing the Consideration Units will bear 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. The Purchaser 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.

(a) The General Partner hereby designates and creates a series of Limited Partner Units to be designated as “Class B Units” and consisting of a total of [__________] Class B Units, having the terms and conditions set forth herein.

(b) The holders of the Class B Units shall have rights upon dissolution and liquidation of the Partnership, including the right to share in any liquidating distributions pursuant to Section 14.3, in accordance with Article XIV of the Partnership Agreement.

(i) Immediately before the close of business on the Conversion Date, the Class B Units shall automatically convert into LP Units on a one-for-one basis.

(ii) Upon conversion, the rights of a holder of converted Class B Units as holder of Class B Units shall cease with respect to such converted Class B Units, including any rights under this Agreement with respect to holders of Class B Units, and such Person shall continue to be a Limited Partner and have the rights of a holder of LP Units under this Agreement. All Class B Units shall, upon the Conversion Date, be deemed to be transferred to, and cancelled by, the Partnership in exchange for the LP Units into which the Class B Units converted.

(iii) The Partnership shall pay any documentary, stamp or similar issue or transfer taxes or duties relating to the issuance or delivery of LP Units upon conversion of the Class B Units. However, the holder shall pay any tax or duty which may be payable relating to any transfer involving the issuance or delivery of LP Units in a name other than the holder’s name. The Transfer Agent may refuse to deliver the Certificate representing LP Units being issued in a name other than the holder’s name until the Transfer Agent receives a sum sufficient to pay any tax or duties which will be due because the shares are to be issued in a name other than the holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation.

(iv) (A) The Partnership shall keep free from preemptive rights a sufficient number of LP Units to permit the conversion of all outstanding Class B Units into LP Units to the extent provided in, and in accordance with, this Section 4.8(c).

(B) All LP Units delivered upon conversion of the Class B Units shall be newly issued, shall be duly authorized and validly issued, and shall be free from preemptive rights and free of any lien or adverse claim.

Exhibit A to Unit Purchase Agreement

(C) The Partnership shall comply with all applicable securities laws regulating the offer and delivery of any LP Units upon conversion of Class B Units and, if the LP Units are then listed or quoted on the New York Stock Exchange, or any other National Securities Exchange or other market, shall list or cause to have quoted and keep listed and quoted the LP Units issuable upon conversion of the Class B Units to the extent permitted or required by the rules of such exchange or market.

(D) Notwithstanding anything herein to the contrary, nothing herein shall give to any holder of Class B Units any rights as a creditor in respect of its right to conversion.

(d) Distributions.

(i) Each Class B Unit shall have the right to share in distributions pursuant to Section 5.2(a) on a pro rata basis with the other Units. All or any portion of each distribution payable in respect of the Class B Units (the “Class B Unit Distribution”) may, at the election of the Partnership, be paid in Class B Units (any amount of such Class B Unit Distribution so paid in PIK Units, the “PIK Distribution Amount”). The number of PIK Units to be issued in connection with a PIK Distribution Amount shall be the quotient of (A) the PIK Distribution Amount divided by (B) the volume-weighted average price of the Partnership’s LP Units for the ten (10) trading days immediately preceding the date the Class B Unit Distribution is declared less a discount of 15%; provided that instead of issuing any fractional PIK Units, the Partnership shall round the number of PIK Units issued down to the next lower whole PIK Unit and pay cash in lieu of such fractional units, or at the Partnership’s option, the Partnership may round the number of PIK Units issued up to the next higher whole PIK Unit.

(ii) Notwithstanding anything in this Section 4.8(d) to the contrary, with respect to Class B Units that are converted into LP Units, the holder thereof shall not be entitled to a Class B Unit Distribution and an LP Unit distribution with respect to the same period, but shall be entitled only to the distribution to be paid based upon the class of Units held as of the close of business on the applicable Record Date.

(iii) When any PIK Units are payable to a holder of Class B Units pursuant to this Section 4.8, the Partnership shall issue the PIK Units to such holder no later than the date the corresponding distributions are made pursuant to Section 5.2(a) (the date of issuance of such PIK Units, the “PIK Payment Date”). On the PIK Payment Date, the Partnership shall issue to such holder of Class B Units a certificate or certificates for the number of PIK Units to which such holder of Class B Units shall be entitled.

(iv) For purposes of maintaining Capital Accounts, if the Partnership distributes one or more PIK Units to a holder of Class B Units, (i) the

Exhibit A to Unit Purchase Agreement

Partnership shall be treated as distributing cash to such holder of Class B Units equal to the PIK Distribution Amount, and (ii) the holder of Class B Units shall be deemed to have recontributed to the Partnership in exchange for such newly issued PIK Units an amount of cash equal to the PIK Distribution Amount less the amount of any cash distributed by the Partnership in lieu of fractional PIK Units.

(e) The Class B Units will have such voting rights pursuant to the Agreement as such Class B Units would have if they were LP Units that were then outstanding and shall vote together with the LP Units as a single class, except that the Class B Units shall be entitled to vote as a separate class on any matter on which Unitholders are entitled to vote that adversely affects the rights or preferences of the Class B Units in relation to other classes of Partnership Interests in any material respect or as required by law. The approval of a majority of the Class B Units shall be required to approve any matter for which the holders of the Class B Units are entitled to vote as a separate class.

(f) The Class B Units will be evidenced by Certificates in such form as the General Partner may approve (containing appropriate legends concerning transfer restrictions, securities laws and any other requirements).

3. Article IV is hereby amended to add a new Section 4.9 implementing certain transfer restrictions on Units:

Section 4.9 Transfers of Privately Placed Units. The transfers of a Privately Placed Unit shall be subject to Section 5.1(c)(iii) and 5.1(d)(iii).

4. Section 5.1(a) is hereby amended and restated as follows:

(a) The Partnership shall maintain for each Partner a separate Capital Account with respect to its Partnership Interests in accordance with the regulations issued pursuant to Section 704 of the Code. The Capital Account of any Partner shall be increased by (i) the Net Agreed Value of all Capital Contributions made by such Partner in exchange for its Partnership Interest and (ii) all items of income and gain computed in accordance with Section 5.1(b) and allocated to such Partner pursuant to Section 5.1(c) and reduced by (iii) the Net Agreed Value of all distributions of cash or property (other than PIK Units) made to such Partner with respect to its Partnership Interest and (iv) all items of deduction and loss computed in accordance with Section 5.1(b) and allocated to such Partner pursuant to Section 5.1(c). The initial Capital Account balance in respect of each Class B Unit, PIK Unit and PIPE Unit shall be determined by reference to the fair market value of an LP Unit on the date such Unit is issued. Immediately following the initial creation of a Capital Account balance in respect of each PIK Unit and each Unit issued pursuant to the PIPE Unit Purchase Agreements or the Registration Rights Agreements, each Unitholder acquiring such a Unit at original issuance shall be deemed to have received a cash distribution or to have made a cash contribution, as the case may be, in respect of such Unit equal to the amount by which (A) the fair market value of an LP Unit on the date of issuance exceeds or is less than, as the case may be, (B) the Issue Price for such Unit.

Exhibit A to Unit Purchase Agreement

5. Section 5.1(c)(iii) is hereby amended and restated as follows:

(iii) (A) To preserve uniformity of Units, the General Partner may make special allocations of income or deduction pursuant to Section 6.1(c) that do not have a material adverse effect on the Limited Partners and are consistent with the principles of Section 704 of the Code.

(B) At the election of the General Partner with respect to any taxable period ending upon, or after, the conversion of the Class B Units into LP Units, all or a portion of the remaining items of Partnership gross income or gain for such taxable period shall be allocated to each Partner holding converted Class B Units in the proportion of the number of converted Class B Units held by such Partner to the total number of Converted Class B Units then outstanding, until each such Partner has been allocated an amount of gross income or gain that increases the Capital Account maintained with respect to such converted Class B Units to an amount that after taking into account the other allocations of income, gain, loss and deduction to be made with respect to such taxable period will equal the product of (I) the number of converted Class B Units held by such Partner and (II) the Per Unit Capital Amount for an LP Unit evidenced by an LP Unit Certificate that is not a Privately Placed Unit. The purpose of this allocation is to establish uniformity between the Capital Accounts underlying converted Class B Units and the Capital Accounts underlying LP Units that are not Privately Placed Units prior to the certification of such converted Class B Units as LP Units.

(C) With respect to an event triggering an adjustment to the Carrying Value of Partnership property pursuant to Section 5.1(e) during any taxable period of the Partnership ending upon, or after, the issuance of Privately Placed Units, any Unrealized Gains and Unrealized Losses shall be allocated among the Partners in a manner that to the nearest extent possible results in the Capital Accounts maintained with respect to the Privately Placed Units on a per unit basis equaling the Per Unit Capital Amount for an LP Unit that is not a Privately Placed Unit.

(D) With respect to any taxable period of the Partnership ending upon, or after, the transfer of a PIPE Unit or PIK Unit or converted Class B Unit to a Person that is not an Affiliate of the holder, Partnership items of income or gain for such taxable period shall be allocated 100% to the Partner transferring such PIPE Unit or PIK Unit or converted Class B Unit in a manner that to the nearest extent possible results in the Capital Account maintained with respect to such PIPE Unit or PIK Unit or converted Class B Unit on a per unit basis equaling the Per Unit Capital Amount for an LP Unit that is not a Privately Placed Unit.

6. Section 5.1(d) is amended to add a new Section 5.1(d)(iii) as follows:

(iii) Immediately prior to the transfer of a Privately Placed Unit by a holder thereof (other than a transfer to an Affiliate unless the General Partner elects to have this subparagraph 5.1(d)(iii) apply), the aggregate Capital Account maintained for such Person with respect to its Privately Placed Units will (A) first, be allocated to the Privately Placed Units to be transferred in an amount equal to the product of (x) the

Exhibit A to Unit Purchase Agreement

number of such Privately Placed Units to be transferred and (y) the Per Unit Capital Amount for an LP Unit that is not a Privately Placed Unit, and (B) second, any remaining positive balance in such Capital Account will be retained by the transferor, regardless of whether it has retained any Privately Placed Units and if the remaining balance would be negative, items of Partnership income and gain shall be specially allocated to such transferor Partner in an amount and manner sufficient to eliminate the deficit in its Capital Account as quickly as possible. Following any such allocation, the transferor’s Capital Account, if any, maintained with respect to the retained Privately Placed Units, if any, will have a balance equal to the amount allocated under clause (B) hereinabove, and the transferee’s Capital Account established with respect to the transferred Privately Placed Units will have a balance equal to the amount allocated under clause (A) hereinabove.

7. Section 5.1(e) is hereby amended and restated as follows:

(e) If any additional Units (or other Partnership Interests) are to be issued pursuant to Section 4.3 for cash or Contributed Property, as the consideration for the provision of services, or if any Partnership property is to be distributed (other than a distribution of cash that is not a redemption or retirement of a Partnership Interest), the Capital Accounts of the Partners (and the Carrying Values of all Partnership properties) shall, immediately prior to such issuance or distribution, be adjusted (consistent with the provisions hereof and of Section 704(b) of the Code) upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to all Partnership properties (as if such Unrealized Gain or Unrealized Loss had been recognized upon an actual sale of such properties immediately prior to such issuance or on the date of such conversion). In determining such Unrealized Gain or Unrealized Loss, the fair market value of Partnership properties, as of any date of determination, shall be determined by the General Partner using such method of valuation as it may adopt. In making its determination of the fair market values of individual properties, the General Partner may determine that it is appropriate to first determine an aggregate value for the Partnership, based on the current trading price of the LP Units or any Issue Price (without reduction for any underwriting discount or similar fees) of concurrent Units and taking fully into account the fair market value of the Partnership Interests of all Partners at such time, and then allocate such aggregate value among the individual properties of the Partnership (in such manner as it determines appropriate).

8. Article V is hereby amended to add a new Section 5.2(c) as follows:

(c) For the avoidance of doubt, upon any pro rata distribution of Partnership Securities to all Record Holders of LP Units or any subdivision or combination (or reclassified into a greater or smaller number) of LP Units, the Partnership will proportionately adjust the number of Class B Units as follows: (a) if the Partnership issues Partnership Securities as a distribution on its LP Units or subdivides the LP Units (or reclassifies them into a greater number of LP Units) then the Class B Units shall be subdivided into a number of Class B Units equal to the result of multiplying the number of Class B Units by a fraction, (A) the numerator of which shall be the sum of the number of LP Units outstanding immediately prior to such distribution or subdivision plus the total number of Partnership Securities constituting such distribution or newly created by such subdivision; and (B) the denominator of which shall be the number of LP Units outstanding immediately prior to such distribution or subdivision; and (b) if the Partnership

Exhibit A to Unit Purchase Agreement

combines the LP Units (or reclassifies them into a smaller number of LP Units) then the Class B Units shall be combined into a number of Class B Units equal to the result of multiplying the number of Class B Units by a fraction, (A) the numerator of which shall be the sum of the number of LP Units outstanding immediately following such combination; and (B) the denominator of which shall be the number of LP Units outstanding immediately prior to such combination.

B. Agreement in Effect. Except as hereby amended, the Partnership Agreement shall remain in full force and effect.

C. Applicable Law. This Amendment shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to principles of conflicts of laws.

D. SEVERABILITY. EACH PROVISION OF THIS AMENDMENT SHALL BE CONSIDERED SEVERABLE AND IF FOR ANY REASON ANY PROVISION OR PROVISIONS HEREIN ARE DETERMINED TO BE INVALID, UNENFORCEABLE OR ILLEGAL UNDER ANY EXISTING OR FUTURE LAW, SUCH INVALIDITY, UNENFORCEABILITY OR ILLEGALITY SHALL NOT IMPAIR THE OPERATION OF OR AFFECT THOSE PORTIONS OF THIS AMENDMENT THAT ARE VALID, ENFORCEABLE AND LEGAL.

Exhibit A to Unit Purchase Agreement

Exhibit B — Form of Opinion of ▇▇▇▇▇▇ & ▇▇▇▇▇▇ 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 ▇▇▇▇▇▇ & ▇▇▇▇▇▇ L.L.P., counsel for Buckeye, addressed to the Purchaser and dated the Closing Date in form satisfactory to the Purchaser, stating that:

(i) 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.

(ii) To such counsel’s knowledge, except as described in the Buckeye SEC Documents filed prior to the date of the Purchase Agreement and pursuant to the Unit Purchase Agreements, 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.

(iii) 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 LP Act).

(iv) The LP Units issuable upon conversion of those 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 and, in each case, the limited partner interests represented thereby, upon issuance in accordance with the terms of Class B Units as reflected in the Class B Amendment, 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).

(v) Except for the approvals required by the Commission in connection with Buckeye’s obligations under the Registration Rights Agreement, no authorization, consent, approval, waiver, license, qualification, filing, declaration, qualification 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 by the Operative Documents, except those that

Exhibit B to Unit Purchase Agreement
(First Reserve)

have been obtained or as may be required under state securities or “Blue Sky” laws, as to which we do not express any opinion.

(vi) Buckeye is not, and after giving effect to the Acquisition will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(vii) 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; provided that such counsel will express no opinion as to any subsequent sale.

(viii) The holders of outstanding LP Units are not entitled to statutory, preemptive or, to such counsel’s knowledge, other similar contractual rights to subscribe for the Consideration Units.

(ix) 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 hereby or thereby (including issuance of LP Units upon conversion of those 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, Delaware LLC Act or U.S. federal law, which in the case of clauses (B) or (C) would be reasonably expected to have a Material Adverse Effect; provided, however, that no opinion is expressed pursuant to this paragraph (ix) with respect to federal or state securities or anti-fraud statutes, rules or regulations.

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.
