At the Effective Time, the unit transfer books of OILT shall be closed immediately and there shall be no further registration of transfers on the unit transfer books of OILT with respect to OILT Common Units.

Section 3.3 Exchange of Certificates.

(a) Exchange Agent. Promptly after the Effective Time, Partners shall deposit or shall cause to be deposited with the Exchange Agent for the benefit of the holders of OILT Public Common Units, for exchange in accordance with this Article III, through the Exchange Agent, New Common Units and cash as required by this Article III. Partners agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any distributions pursuant to Section 3.2 and Section 3.3(c) and to make payments in lieu of any fractional New Common Units pursuant to Section 3.3(e), in each case without interest. Any cash and New Common Units deposited with the Exchange Agent (including as payment for any fractional New Common Units in accordance with Section 3.3(e) and any distributions with respect to such fractional New Common Units in accordance with Section 3.3(c)) shall hereinafter be referred to as the “Exchange Fund.” The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be paid for OILT Common Units pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Sections 3.2, 3.3(c) and 3.3(e), the Exchange Fund shall not be used for any other purpose.

(b) Exchange Procedures. Promptly after the Effective Time, Partners shall instruct the Exchange Agent to mail to each record holder of OILT Public Common Units as of the Effective Time (i) a letter of transmittal (which shall specify that in respect of certificated OILT Common Units, delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent, and which shall be in customary form and agreed to by Partners and OILT prior to the Effective Time) and (ii) instructions for use in effecting the surrender of the Certificates or Book-Entry Units in exchange for the Merger Consideration payable in respect of OILT Common Units represented by such Certificates or Book-Entry Units, as applicable. Promptly after the Effective Time, upon surrender of Certificates, if any, for cancellation to the Exchange Agent together with such letters of transmittal, properly completed and duly executed, and such other documents (including in respect of Book-Entry Units) as may be required pursuant to such instructions, each holder who held OILT Public Common Units immediately prior to the Effective Time shall be entitled to receive upon surrender of the Certificates or Book-Entry Units therefor (a) New Common Units representing, in the aggregate, the whole number of New Common Units that such holder has the right to receive pursuant to this Article III (after taking into account all OILT Public Common Units then held by such holder) and (b) a check in an amount equal to the aggregate amount of cash that such holder has the right to receive pursuant to this Article III, including cash payable in lieu of any fractional New Common Units pursuant to Section 3.3(e) and distributions pursuant to Section 3.3(c). No interest shall be paid or accrued on any Merger Consideration, any cash payment in lieu of fractional New Common Units, or on any unpaid distributions payable to holders of Certificates or Book-Entry Units. In the event of a transfer of ownership of OILT Public Common Units that is not registered in the transfer records of OILT, the Merger Consideration payable in respect of such OILT Public Common Units may be paid to a transferee, if the Certificate representing such OILT Public Common Units or evidence of ownership of the Book-Entry Units is presented to the Exchange Agent, and in the case of both certificated and book-entry OILT Public Common Units, accompanied by all documents required to evidence and effect such transfer and the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other Taxes required by reason of the delivery of the Merger Consideration in any name other than that of the record holder of such OILT Public Common Units, or shall establish to the satisfaction of the Exchange Agent that such Taxes have been paid or are not payable. Until the required documentation has been delivered and Certificates, if any, have been surrendered, as contemplated by this Section 3.3, each Certificate or Book-Entry Unit shall be deemed at any time after the Effective Time to represent only the right to receive upon such delivery and surrender the Merger Consideration payable in respect of OILT Public Common Units and any cash or distributions to which such holder is entitled pursuant to Section 3.2 and Section 3.3.

(c) Distributions with Respect to Unexchanged OILT Common Units. No distributions declared or made with respect to Partners Common Units with a record date after the Effective Time shall be paid to the holder of any OILT Common Units with respect to New Common Units that such holder would be entitled to receive in accordance herewith and no cash payment in lieu of fractional New Common Units shall be paid to any such holder, in each case until such holder shall have delivered the required documentation and surrendered any Certificates or Book-Entry Units as contemplated by this Section 3.3. Subject to applicable Law, following compliance with the requirements of Section 3.3(b), there shall be paid to such holder of New Common Units issuable in exchange therefor, without interest, (i) promptly after the time

of such compliance, the amount of any cash payable in lieu of fractional New Common Units to which such holder is entitled pursuant to Section 3.3(e) and an amount in cash equal to any Partners distributions with a record date after the Effective Time and a payment date prior to such compliance with Section 3.3(b) payable with respect to such New Common Units, and (ii) on the appropriate payment date with respect thereto, the amount of distributions with a record date after the Effective Time but prior to such delivery and surrender and with a payment date subsequent to such compliance payable with respect to such New Common Units.

(d) Further Rights in OILT Common Units. The Merger Consideration issued upon conversion of an OILT Common Unit in accordance with the terms hereof (including any cash paid pursuant to Section 3.3(c) or Section 3.3(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such OILT Common Unit.

(e) Fractional New Common Units. No certificates or scrip of New Common Units representing fractional New Common Units or book entry credit of the same shall be issued upon the surrender of OILT Common Units outstanding immediately prior to the Effective Time in accordance with Section 3.3(b), and such fractional interests will not entitle the owner thereof to vote or to have any rights as a holder of any New Common Units. Notwithstanding any other provision of this Agreement, each holder of OILT Common Units converted in the Merger who would otherwise have been entitled to receive a fraction of a New Common Unit (after taking into account all OILT Common Units exchanged by such holder) shall receive, in lieu thereof, cash (without interest rounded up to the nearest whole cent) in an amount equal to the product of (i) the Average Closing Price as of the Closing Date and (ii) the fraction of a New Common Unit that such holder would otherwise be entitled to receive pursuant to this Article III. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, if any, the Exchange Agent shall so notify Partners, and Partners shall, or shall cause the Surviving Entity to, deposit such amount with the Exchange Agent and shall cause the Exchange Agent to forward payments to such holders of fractional interests, if any, subject to and in accordance with the terms hereof. To the extent applicable, each holder of OILT Common Units shall be deemed to have consented for U.S. federal income tax purposes (and to the extent applicable, state or local income tax purposes) to report the cash received for fractional New Common Units in the Merger as a sale of a portion of the holder’s OILT Common Units to Partners consistent with Treasury Regulation Section 1.708-1(c)(4).

(f) Termination of Exchange Fund. Any portion of the Exchange Fund constituting New Common Units or cash that remains undistributed to the holders of OILT Common Units after 180 days following the Effective Time shall be delivered to Partners upon demand by Partners and, from and after such delivery, any former holders of OILT Common Units who have not theretofore complied with this Article III shall thereafter look only to Partners for the Merger Consideration payable in respect of such OILT Common Units, any distributions with respect to OILT Common Units to which they are entitled pursuant to Section 3.2, any cash in lieu of fractional New Common Units to which they are entitled pursuant to Section 3.3(e) and any distributions with respect to New Common Units to which they are entitled pursuant to Section 3.3(c), in each case, without any interest thereon. Any amounts remaining unclaimed by holders of OILT Common Units immediately prior to such time as such amounts would otherwise escheat to or become the property of any governmental entity shall, to the extent permitted by applicable Law, become the property of Partners, free and clear of any Liens, claims or interest of any Person previously entitled thereto.

(g) No Liability. To the fullest extent permitted by Law, none of OTLP GP, Partners, OILT, or the Surviving Entity shall be liable to any holder of OILT Common Units for any Partners Common Units (or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(h) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Partners, the posting by such Person of a bond, in such reasonable amount as Partners may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect of OILT Common Units represented by such Certificate and any distributions to which the holders thereof are entitled pursuant to Section 3.2 and Section 3.3.

(i) Withholding. Each of Partners, the Surviving Entity and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of OILT Common Units such amounts as Partners, the Surviving Entity or the Exchange Agent reasonably deems to be required to deduct and withhold under the Code or any provision of state, local, or foreign Tax Law, with respect to the making of such payment. To the extent that amounts are so deducted and withheld by Partners, the Surviving Entity or the Exchange Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of OILT Common Units in respect of whom such deduction and withholding was made by Partners, the Surviving Entity or the Exchange Agent, as the case may be.

(j) Book Entry and Admission of Holders of New Common Units as Additional Limited Partners of Partners. All New Common Units to be issued in the Merger shall be issued in book-entry form, without physical certificates. Upon the issuance of New Common Units to the holders of OILT Common Units in accordance with this Section 3.3 and the compliance by such holders with the requirements of Section 10.4 of the Partners Partnership Agreement, which requirements may be satisfied by each holder of OILT Common Units by the execution and delivery by such holder of a completed and executed letter of transmittal, (i) such holder shall be deemed to have made a capital contribution to Partners in accordance with the Partners Partnership Agreement and (ii) Partners GP shall be deemed to have automatically consented to the admission of such holder as a limited partner of Partners in respect of its New Common Units and shall reflect such admission on the books and records of Partners.

(k) Investment of the Exchange Fund. Partners shall cause the Exchange Agent to invest any cash included in the Exchange Fund as directed by Partners on a daily basis; provided that any investment of such Exchange Fund shall be limited to direct short-term obligations of, or short-term obligations fully guaranteed as to principal and interest by, the U.S. government and that no such investment or loss thereon shall affect the amounts payable or the timing of the amounts payable to OILT Unitholders pursuant to the other provisions of this Section 3.3. Any interest and other income resulting from such investments shall be paid promptly to Partners.

Section 3.4 Anti-Dilution Provisions. In the event of any subdivisions, reclassifications, recapitalizations, splits, unit distributions, combinations or exchange of units with respect to, or Rights in respect of, OILT Common Units or Partners Common Units (in each case, as permitted pursuant to Section 4.3), the number of New Common Units to be issued in the Merger and the Average Closing Price of Partners Common Units will be correspondingly adjusted to provide to the holders of OILT Common Units the same economic effect as contemplated by this Agreement prior to such event.

Section 3.5 Treatment of OILT Equity-Based Awards. As of the date of this Agreement, there are no outstanding unvested restricted OILT Common Units, and there are no outstanding unit appreciation rights or options or other awards issued under the OILT Partners, L.P. Long-Term Incentive Plan, as it may be further amended from time to time.

Section 3.6 No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated by this Agreement.

Section 3.7 Tax Characterization of Merger. OILT and Partners each acknowledges and agrees that for federal income Tax purposes the exchange of OILT Public Common Units for New Common Units pursuant to the Merger shall qualify as an exchange to which Section 721(a) of the Code applies. Each of OILT and Partners agrees to prepare and file all U.S. federal income Tax Returns in accordance with the foregoing qualification and treatment and shall not take any position inconsistent therewith on any such Tax Return, or in the course of any audit, litigation or other proceeding with respect to U.S. federal income Taxes, except as otherwise required by applicable Laws following a final determination by a court of competent jurisdiction or other final administrative decision by an applicable Governmental Authority.

ARTICLE VI

COVENANTS

Each of the OILT Parties hereby covenants to and agrees with the Partners Parties, and each of the Partners Parties hereby covenants to and agrees with the OILT Parties, that:

Section 6.1 Best Efforts. Subject to the terms and conditions of this Agreement, it shall use its commercially reasonable best efforts in good faith to take, or cause to be taken, all actions, and to do, or cause to be done, all things necessary, proper, desirable or advisable under applicable Laws, so as to permit consummation of the Merger promptly and otherwise to enable consummation of the transactions contemplated hereby, including obtaining (and cooperating with the Other Parties to obtain) any third-party approval that is required to be obtained by Partners or OILT or any of their respective Subsidiaries in connection with the Merger and the other transactions contemplated by this Agreement, using commercially reasonable best efforts to lift or rescind any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby, and using commercially reasonable best efforts to defend any litigation seeking to enjoin, prevent or delay the consummation of the transactions contemplated hereby or seeking material damages, and each shall cooperate fully with the Other Parties hereto to that end, and shall furnish to the Other Parties copies of all correspondence, filings and communications between it and its Affiliates and any Governmental Authority with respect to the transactions contemplated hereby.

Section 6.2 OILT Unitholder Meeting.

(a) Subject to the terms and conditions of this Agreement, and except as permitted by Section 6.2(b), OILT shall take, in accordance with applicable Law, applicable stock exchange rules and the OILT Existing Partnership Agreement, all action necessary to call, hold and convene the OILT Meeting to consider and vote upon the approval of this Agreement and the Merger, and any other matters required to be approved by OILT Unitholders for consummation of the OILT Merger Transactions, promptly after the date hereof. Subject to Section 6.2(b) and Section 6.6, the OTLP GP Conflicts Committee and the OTLP GP Board shall recommend approval of this Agreement and the Merger to the holders of OILT Common Units (the “OILT Recommendation”), and, subject to Section 6.6, OILT shall take all reasonable lawful action to solicit such approval by the holders of OILT Common Units.

(b) Notwithstanding anything to the contrary in this Agreement, if there occurs an OILT Change in Recommendation in accordance with this Agreement, OILT shall not be required to call, hold or convene the OILT Meeting.

(c) OILT shall not, without the prior written consent of Partners (which consent shall not be unreasonably withheld, delayed or conditioned), adjourn or postpone the OILT Meeting; provided that OILT may, without the prior written consent of Partners but after consultation with Partners, adjourn or postpone the OILT Meeting (i) if, as of the time for which the meeting is originally scheduled (as set forth in the Proxy Statement/Prospectus), there are an insufficient number of OILT Common Units represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the OILT Meeting, (ii) if the failure to adjourn or postpone the meeting is determined by the OTLP GP Conflicts Committee to be reasonably likely to result in a violation of Law for the distribution of any required supplement or amendment to the Proxy Statement/Prospectus, or (iii) for a single period not to exceed ten (10) Business Days, to solicit additional proxies if necessary to obtain OILT Unitholder Approval. Once OILT has established a record date for the OILT Meeting, OILT shall not change such record date or establish a different record date for the meeting without the prior written consent of Partners (which consent shall not be unreasonably withheld, delayed or conditioned). Without the prior written consent of Partners, the adoption of this Agreement shall be the only matter (other than matters of procedure and matters required by Law to be voted on by OILT Unitholders in connection with the approval of this Agreement and the transactions contemplated hereby) that OILT shall propose to be acted on by the OILT Unitholders at the OILT Meeting.

Section 6.3 Registration Statement.

(a) Each of Partners and OILT agrees to cooperate in the preparation of the Registration Statement (including the Proxy Statement/ Prospectus constituting a part thereof and all related documents) to be filed by Partners with the SEC in connection with the issuance of the New Common Units in the Merger as contemplated by this Agreement. Provided OILT has cooperated as required above, Partners agrees to file the Registration Statement with the SEC as promptly as practicable. Each of OILT and Partners agrees to use all commercially reasonable best efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as practicable after filing thereof. Partners also agrees to use commercially reasonable best efforts to obtain all necessary state securities law or “Blue Sky” permits and

approvals required to carry out the transactions contemplated by this Agreement. Each of Partners and OILT agrees to furnish to the other party all information concerning Partners, Partners GP and their respective Subsidiaries or OILT, OTLP GP and their respective Subsidiaries, as applicable, and the officers, directors and unitholders of Partners and OILT and any applicable Affiliates, as applicable, and to take such other action as may be reasonably requested in connection with the foregoing. No filing of the Registration Statement will be made by Partners, and no filing of the Proxy Statement/Prospectus will made by Partners or OILT, in each case without providing the other party a reasonable opportunity to review and comment thereon.

(b) Each of OILT and Partners agrees, as to itself and its Subsidiaries, that (i) none of the information supplied or to be supplied by it for inclusion or incorporation by reference in the Registration Statement will, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (ii) the Proxy Statement/Prospectus and any amendment or supplement thereto will, at the date of mailing to the holders of OILT Common Units and at the time of the OILT Meeting, not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of OILT and Partners further agrees that if it shall become aware prior to the Closing Date of any information that would cause any of the statements in the Registration Statement to be false or misleading with respect to any material fact, or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not false or misleading, it will promptly inform the other party thereof and take the necessary steps to correct such information in an amendment or supplement to the Registration Statement.

(c) Partners will advise OILT, promptly after Partners receives notice thereof, of (i) the time when the Registration Statement has become effective or any supplement or amendment has been filed, (ii) the issuance of any stop order or the suspension of the qualification of the New Common Units for offering or sale in any jurisdiction, (iii) the initiation or threat of any proceeding for any such purpose, or (iv) any request by the SEC for the amendment or supplement of the Registration Statement or for additional information.

(d) OILT will use its commercially reasonable best efforts to cause the Proxy Statement/Prospectus to be mailed to the OILT Unitholders as soon as practicable after the effective date of the Registration Statement.

Section 6.4 Press Releases. Prior to an OILT Change in Recommendation, if any, each of OILT and Partners will not, without the prior approval of the OTLP GP Conflicts Committee in the case of Partners and the Partners GP Board in the case of OILT, issue any press release or written statement for general circulation relating to the transactions contemplated hereby, except as otherwise required by applicable Law or the rules of the NYSE, in which case it will consult with the other party before issuing any such press release or written statement.

Section 6.5 Access; Information.

(a) Upon reasonable notice and subject to applicable Laws relating to the exchange of information, each party shall, and shall cause its Subsidiaries to, afford the Other Parties and their Representatives, access, during normal business hours throughout the period prior to the Effective Time, to all of its properties, books, contracts, commitments and records, and to its Representatives, and, during such period, it shall, and shall cause its Subsidiaries to, furnish promptly to such Person and its Representatives (i) a copy of each material report, schedule and other document filed by it pursuant to the requirements of federal or state securities law (other than reports or documents that Partners or OILT or their respective Subsidiaries, as the case may be, are not permitted to disclose under applicable Law) and (ii) all other information concerning its business, properties and personnel as the Other Parties may reasonably request. Neither OILT nor Partners nor any of their respective Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would jeopardize the attorney-client privilege (or other applicable privilege or immunity) of the institution in possession or control of such information or contravene any Law, fiduciary duty or binding agreement entered into prior to the date of this Agreement. The parties hereto will make appropriate substitute disclosure arrangements under the circumstances in which the restrictions of the immediately preceding sentence apply.

(b) Partners and OILT, respectively, will not use any information obtained pursuant to this Section 6.5 (to which it was not entitled under Law or any agreement other than this Agreement) for any purpose unrelated to (i) the consummation of the transactions contemplated by this Agreement or (ii) the matters contemplated by Section 6.6 in accordance with the terms thereof, and will hold all information and documents obtained pursuant to this Section 6.5 in confidence. No investigation by either party of the business and affairs of the other shall affect or be deemed to modify or waive any representation, warranty, covenant or agreement in this Agreement, or the conditions to either party’s obligation to consummate the transactions contemplated by this Agreement.

Section 6.6 No Solicitation; Acquisition Proposals; Change in Recommendation.

(a) Neither OTLP GP nor OILT shall, and they shall use their commercially reasonable best efforts to cause their Representatives not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or the making or submission of any proposal that constitutes, or may reasonably be expected to lead to, an Acquisition Proposal, or (ii) participate in any discussions or negotiations regarding, or furnish to any person any non-public information with respect to, any Acquisition Proposal. Notwithstanding the foregoing, but subject to the limitations in Sections 6.6(b) and (c), nothing contained in this Agreement shall prohibit OILT or any of its Representatives from furnishing or making available any information or data pertaining to OILT, or entering into or participating in discussions or negotiations with, any person that makes an unsolicited written Acquisition Proposal that did not result from a material, knowing and intentional breach of this Section 6.6 (a “Receiving Party”), if (i) the OTLP GP Conflicts Committee after consultation with its outside legal counsel and financial advisors, determines in its good faith judgment (A) that such Acquisition Proposal constitutes or is likely to result in a Superior Proposal, and (B) that failure to take such action would be inconsistent with its duties under the OILT Existing Partnership Agreement and applicable Law and (ii) prior to furnishing or making available any such non-public information to such Receiving Party (including any information pertaining to OILT Subsidiaries in which Partners has an equity interest or transactions to which Partners is a party), OILT receives from such Receiving Party an executed Confidentiality Agreement.

(b) Except as otherwise provided in this Section 6.6(b), neither the OTLP GP Conflicts Committee nor the OTLP GP Board shall: (i) (A) withdraw, modify or qualify in any manner adverse to Partners the OILT Recommendation or (B) publicly approve or recommend, or publicly propose to approve or recommend, any Acquisition Proposal (any action described in this clause (i) being referred to as an “OILT Change in Recommendation”); or (ii) approve, adopt or recommend, or publicly propose to approve, adopt or recommend, or allow OILT or any of its Subsidiaries to execute or enter into, any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition agreement, option agreement, joint venture agreement, partnership agreement, or other similar contract or any tender or exchange offer providing for, with respect to, or in connection with, any Acquisition Proposal. Notwithstanding the foregoing, at any time prior to obtaining the OILT Unitholder Approval, the OTLP GP Conflicts Committee may make an OILT Change in Recommendation if it has concluded in its good faith judgment, after consultation with its outside legal counsel and financial advisors, that failure to make an OILT Change in Recommendation would be inconsistent with its duties under the OILT Existing Partnership Agreement and applicable Law; provided, however, that (1) the OTLP GP Conflicts Committee shall not be entitled to exercise its right to make an OILT Change in Recommendation pursuant to this sentence unless OILT and OTLP GP have: (v) complied in all material respects with this Section 6.6, (w) provided to Partners and the Partners Audit Committee three (3) Business Days prior written notice (such notice, a “Notice of Proposed Recommendation Change”) advising Partners that the OTLP GP Conflicts Committee intends to take such action and specifying the reasons therefor in reasonable detail, including, if applicable, the material terms and conditions of any Superior Proposal that is the basis of the proposed action and the identity of the Person making the proposal (it being understood and agreed that any material amendment to the terms of any such Superior Proposal shall require a new Notice of Proposed Recommendation Change and an additional three (3) Business Day period), (x) if applicable, provided to Partners all materials and information delivered or made available to the Person or group of persons making any Superior Proposal in connection with such Superior Proposal (to the extent not previously provided), (y) OILT has negotiated, and has caused its Representatives to negotiate, in good faith with Partners during such notice period, to the extent Partners wishes to negotiate, to enable Partners to propose revisions to the terms of this Agreement such that it would permit the OTLP GP Conflicts Committee not to make an OILT Change in Recommendation pursuant to this Section 6.6(b) and (z) upon the end of such notice period, the OTLP GP Conflicts Committee shall have considered in good faith any revisions to the terms of this Agreement proposed by Partners, and shall have determined, after consultation with its financial advisor and outside legal counsel, that the OTLP GP Conflicts Committee’s duties under the OILT Existing Partnership Agreement and applicable Law continue to require an OILT Change in Recommendation and (2) the OTLP GP Conflicts Committee shall not be entitled to make an OILT Change in Recommendation in response to an Acquisition Proposal unless such Acquisition Proposal constitutes a Superior Proposal. Notwithstanding any provision in this Agreement to the contrary, Partners and Partners GP shall maintain, and cause their Representatives to maintain, the confidentiality of all information received from OILT pursuant to this Section 6.6, subject to the exceptions contained in the Confidentiality Agreement. OILT agrees that it and its Affiliates will not enter into any agreement with any Person subsequent to the date of this Agreement which prohibits OILT from

providing any information to Partners in accordance with this Section 6.6. In the event that OILT is otherwise entitled to provide information to a Receiving Party under Section 6.6(a), OILT shall promptly provide or make available to Partners any non-public information concerning OILT or any of its Subsidiaries that is provided or made available to any Receiving Party pursuant to this Section 6.6 that was not previously provided or made available to Partners. Notwithstanding anything in this Agreement to the contrary, for the purposes of this Section 6.6(b), without the prior written consent of Partners, no Acquisition Proposal shall constitute a Superior Proposal if such Acquisition Proposal is conditioned on completion of a Partners Acquisition Proposal.

(c) In addition to the obligations of OILT set forth in this Section 6.6, OILT shall as promptly as practicable (and in any event within the periods set forth later in this sentence) advise Partners orally, within 24 hours after receipt, and in writing, within 48 hours after receipt, of any Acquisition Proposal or any matter giving rise to a OILT Change in Recommendation and the material terms and conditions of any such Acquisition Proposal or any matter giving rise to a OILT Change in Recommendation (including any changes thereto) and the identity of the Person making any such Acquisition Proposal.

Indemnified Parties, any Indemnification Expenses incurred in defending, serving as a witness with respect to or otherwise participating with respect to any Claim or Action in advance of the final disposition of such Claim or Action, including payment on behalf of or advancement to the Indemnified Party of any Indemnification Expenses incurred by such Indemnified Party in connection with enforcing any rights with respect to such indemnification and/or advancement, in each case without the requirement of any bond or other security. The indemnification and advancement obligations of Partners GP, Partners, OTLP GP and the Surviving Entity pursuant to this Section 6.11(a) shall extend to acts or omissions occurring at or before the Effective Time and any Claim or Action relating thereto (including with respect to any acts or omissions occurring in connection with the approval of this Agreement and the consummation of the Merger and the transactions contemplated by this Agreement, including the consideration and approval thereof and the process undertaken in connection therewith and any Claim or Action relating thereto), and all rights to indemnification and advancement conferred hereunder shall continue as to any Indemnified Party who has ceased to be a director or officer of OTLP GP after the date hereof and shall inure to the benefit of such person’s heirs, executors and personal and legal representatives. As used in this Section 6.11(a): (x) the term “Claim” means any threatened, asserted, pending or completed action or proceeding, whether instituted by any party hereto, any Governmental Authority or any other person, that any Indemnified Party in good faith believes might lead to the institution of any action or proceeding, whether civil, criminal, administrative, investigative or other, including any arbitration or other alternative dispute resolution mechanism (“Action”), arising out of or pertaining to matters that relate to such Indemnified Party’s duties or service as a director or officer of OTLP GP or of any of its Subsidiaries or as a trustee of (or in a similar capacity with) any Compensation and Benefit Plan of any thereof; (y) the term “Indemnification Expenses” means reasonable attorneys’ fees and all other reasonable costs, expenses and obligations (including experts’ fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Claim or Action for which indemnification is authorized pursuant to this Section 6.11(a), including any Action relating to a claim for indemnification or advancement brought by an Indemnified Party and (z) the phrase “to the fullest extent authorized or permitted by applicable Law” shall include, but not be limited to, (1) to the fullest extent permitted by any provision of Delaware Law that authorizes or permits additional indemnification by agreement or otherwise, or the corresponding provision of any amendment to or replacement of Delaware Law and (2) to the fullest extent authorized or permitted by any amendments to or replacements of Delaware Law adopted after the date of this Agreement that increase the extent to which an entity may indemnify its directors, officers, trustees, employees, agents, or fiduciaries or persons serving in any capacity in which any Indemnified Party serves. Any amendment, alteration or repeal of Delaware Law that adversely affects any right of any Indemnified Party shall be prospective only and shall not limit or eliminate any such right with respect to any Claim or Action involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment or repeal. Neither Partners, Partners GP, OTLP GP nor the Surviving Entity shall settle, compromise or consent to the entry of any judgment in any actual or threatened Claim or Action in respect of which indemnification has been or could be sought by such Indemnified Party hereunder unless such settlement, compromise or judgment includes an unconditional release of such Indemnified Party from all liability arising out of such Claim or Action without admission or finding of wrongdoing, or such Indemnified Party otherwise consents thereto.

(b) Without limiting the foregoing, the Partners Parties agree that all rights to indemnification, advancement of expenses and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time now existing in favor of the Indemnitees as provided in the OILT Existing Partnership Agreement or the OTLP GP Existing LLC Agreement (or, as applicable, the charter, bylaws, partnership agreement, limited liability company agreement, or other organizational documents of any of OILT’s Subsidiaries) and indemnification agreements of OILT or OTLP GP or any of their respective Subsidiaries shall be assumed by the Surviving Entity, OTLP GP and Partners in the Merger, without further action, at the Effective Time and shall survive the Merger and shall continue in full force and effect in accordance with their terms.

(c) For a period of six years from the Effective Time, the OILT Existing Partnership Agreement, as it may be amended, restated or supplemented from time to time, shall contain provisions no less favorable with respect to indemnification, advancement of expenses and limitations on liability of directors and officers than are set forth in the OILT Existing Partnership Agreement, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Effective Time, were Indemnified Parties, unless such modification shall be required by Law and then only to the minimum extent required by Law.

(d) For a period of six years from the Effective Time, Partners shall, or shall cause EPCO to, maintain in effect the current directors’ and officers’ liability insurance policies with aggregate coverage limits no less than under the policies in existence on the date hereof and covering the Indemnified Parties maintained by EPCO (but may substitute therefor other policies of at least the same coverage and amounts containing terms and conditions that are no less advantageous to the Indemnified Parties so long as that substitution does not result in gaps or lapses in coverage) with respect to matters occurring on or before the Effective Time, but neither Partners nor EPCO will be required to pay annual premiums in excess of 300% of the last annual premiums paid therefor prior to the date hereof and shall purchase as much coverage as is reasonably practicable for that amount if the coverage described in this Section 6.11(d) would cost in excess of that amount.

(e) If Partners GP, Partners, OTLP GP, the Surviving Entity or any of their respective successors or assigns (i) consolidates with or merges with or into any other person and shall not be the continuing or surviving corporation, partnership or other entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of Partners GP, Partners, OTLP GP or the Surviving Entity assume the obligations set forth in this Section 6.11.

(f) Partners GP, Partners and OTLP GP shall cause the Surviving Entity to perform all of the obligations of the Surviving Entity under this Section 6.11.

(g) This Section 6.11 shall survive the consummation of the Merger and is intended to be for the benefit of, and shall be enforceable by, the Indemnified Parties and the Indemnitees and their respective heirs and personal representatives, and shall be binding on Partners GP, Partners, OTLP GP, the Surviving Entity and their respective successors and assigns.

Section 6.12 Notification of Certain Matters. Each of OILT and Partners shall give prompt notice to the other of (a) any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein, and (b) (i) any change in its condition (financial or otherwise) or business or (ii) any litigation or governmental complaints, investigations or hearings, in each case to the extent such change, litigation, complaints, investigations, or hearings results in, or would reasonably be expected to result in, a Material Adverse Effect.

Section 6.13 Rule 16b-3. Prior to the Effective Time, (i) OILT shall take such steps as may be reasonably requested by any party hereto to cause dispositions of OILT equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual who is a director or officer of OILT to be exempt under Rule 16b-3 promulgated under the Exchange Act in accordance with that certain No-Action Letter dated January 12, 1999 issued by the SEC regarding such matters and (ii) Partners shall take such steps as may be reasonably requested by any party hereto to cause dispositions of Partners equity securities (including derivative securities) pursuant to the transactions contemplated by this Agreement by each individual who is a director or officer of Partners to be exempt under Rule 16b-3 promulgated under the Exchange Act in accordance with that certain No-Action Letter dated January 12, 1999 issued by the SEC regarding such matters.

The members of the OTLP GP Board immediately prior to the Effective Time shall continue to serve as members of the OTLP GP Board following the Effective Time unless otherwise determined or removed effective at or after such time by the sole member of OTLP GP in accordance with the OTLP GP Existing LLC Agreement.

Section 6.15 Distributions. Each of OTLP GP and Partners GP shall consult with the Other Party regarding the declaration and payment of distributions in respect of the OILT Common Units and the Partners Common Units and the record and payment dates relating thereto, so that no OILT Unitholder shall receive two distributions, or fail to receive one distribution, for any single calendar quarter with respect to its applicable OILT Common Units or any Partners Common Units any such OILT Unitholder receives in exchange therefor pursuant to the Merger.

(ii) any Governmental Authority has issued a statute, rule, order, decree or regulation or taken any other action, in each case permanently restraining, enjoining or otherwise prohibiting the consummation of the Merger or making the Merger illegal and such statute, rule, order, decree, regulation or other action shall have become final and nonappealable (provided that the terminating party is not then in material breach of Section 6.1);

(iii) OILT (A) determines not to, or otherwise fails to, hold the OILT Meeting in accordance with Section 6.2 or (B) does not obtain the OILT Unitholder Approval at the OILT Meeting; provided, however, that the right to terminate this Agreement under this Section 8.1(b)(iii) shall not be available to a terminating party where the failure to obtain the OILT Unitholder Approval shall have been caused by the action or failure to act of such party and such action or failure to act constitutes a breach by such party of this Agreement;

For purposes of this Agreement, “willful and material breach” means a deliberate act or failure to act, which act or failure to act constitutes in and of itself a material breach of this Agreement that the breaching party had Knowledge would or would reasonably be expected to breach its obligations under this Agreement.
