37

jeopardize the attorney-client privilege, contravene any Applicable Law or binding agreement and (b) in the event of litigation, including arbitration, between them, the parties will abide by and be subject to the discovery, evidentiary, and procedural rules of the governing jurisdiction.

Section 5.04. Director and Officer Indemnification. Enterprise will cause the General Partner and each Oiltanking MLP Entity to do the following:

(a) From and after the Closing Date, Enterprise shall cause to be maintained in effect provisions in the organizational documents of the General Partner and the Oiltanking MLP Entities regarding elimination of liability of directors, indemnification of officers, directors and employees and advancement of expenses that are no less advantageous to the intended beneficiaries than the corresponding provisions in such documents in existence as of the Closing Date.

These rights shall survive the Closing and are intended to benefit, and shall be enforceable by, each Indemnified Person.

(b) If any Proceeding by the Federal Trade Commission, the Antitrust Division of the Department of Justice or an Attorney General of any U.S. State (if such Attorney General is conducting an antitrust review) (collectively, an “Antitrust Authority”) is commenced that questions either the validity or legality of the transactions contemplated hereby or the ownership, control or use of the assets by Enterprise or any Affiliate of the Oiltanking MLP Entities following the Closing under the Competition Laws, the Contributing Parties shall use commercially reasonable efforts to cooperate with Enterprise to (i) defend against such Proceeding, and (ii) in the event an Order is issued in any such Proceeding, to have such Order lifted. In furtherance of the foregoing, unless otherwise prohibited by Applicable Laws or by an Antitrust Authority, the Contributing Parties shall provide notice, as soon as reasonably practicable, to Enterprise or its outside antitrust counsel (including on an outside counsel only basis) of any request for information by an Antitrust Authority and provide advance notice of each response to any such request.

Section 5.06. Public Announcements. The parties agree to consult with each other before issuing any press release or making any public statement with respect to this Agreement or the transactions contemplated hereby and, except for any press releases and public announcements, the making of which may be required by Applicable Law or any listing agreement with any national securities exchange, will not issue any such press release or make any such public statement prior to such consultation.

Section 5.07. M&B Marks.

(a) Enterprise agrees that after the Closing neither Enterprise nor its Affiliates (including the Oiltanking Entities) shall have any rights in and to the names “Oiltanking,” “Marquard & Bahls,” “M&B” or any trademarks, trade names, service marks, trade dress, logos, corporate names, domain names and other source identifiers, emblems, signs or insignia containing or comprising the foregoing, including any mark confusingly similar thereto or derivative thereof (collectively, the “M&B Marks”), and shall not at any time after the Closing market, promote, advertise or offer for sale any products, goods or services utilizing any of the M&B Marks or otherwise hold itself out as having any affiliation with M&B or any of its Affiliates.

Notwithstanding the foregoing, for a period commencing on the date of this Agreement and ending on the earlier of (i) the nine-month anniversary of the Closing Date and (ii) 90 days after the consummation of any merger or any other transaction in which Oiltanking MLP becomes a direct or indirect wholly owned subsidiary of Enterprise (such applicable date, the “M&B Marks Termination Date”), Enterprise and its Affiliates (including the Oiltanking Entities) may use any remaining inventory of materials, including business cards, stationery, packaging materials, displays, signs, promotional materials and other similar materials that include one or more of the M&B Marks to the extent such materials were included in the assets as of the Closing. Enterprise shall indemnify and hold harmless the Contributing Parties and their Affiliates against all Damages incurred as a consequence of the use of the M&B Marks by Enterprise and its Affiliates (including the Oiltanking Entities), and cause the Oiltanking Entities to indemnify and hold harmless the Contributing Parties and their Affiliates against all Damages incurred with respect to their use).

(b) Prior to the M&B Marks Termination Date, Enterprise shall cause the Oiltanking Entities to make the initial filing required to be made with the applicable Governmental Authority to cause each of the Oiltanking Entities whose name includes the name “Oiltanking” to change its name such that its name does not include the name “Oiltanking” and use its commercially reasonable efforts to change any such name as promptly as practicable thereafter.

(c) As promptly as practicable following the M&B Marks Termination Date, Enterprise shall cause the Oiltanking Entities to assign or transfer to Affiliates of M&B designated by the Contributing Parties all right, title or interest in any Oiltanking Intellectual Property Rights containing or comprising M&B Marks.

(a) All Transfer Taxes incurred in connection with the transactions contemplated by this Agreement (including any real property transfer Tax and any similar Tax) shall be borne 50% by Enterprise and 50% by the Contributing Parties. Any Tax Returns that must be filed in connection with Transfer Taxes shall be prepared and filed when due by the party primarily or customarily responsible under the applicable local law for filing such Tax Returns, and such party will use reasonable best efforts to provide such Tax Returns to the other party at least ten days prior to the due date, including extensions, for such Tax Returns. Upon the filing of Tax Returns in connection with Transfer Taxes, the filing party shall provide the other party with evidence satisfactory to the other party that such Transfer Taxes have been filed and paid.

(b) The Parties agree that the portion of Oiltanking MLP’s income allocable to the Subject Interests will be reflected on the federal income Tax Return for OTA and OTB Holdco for the period up to and including the Closing Date, and shall be reflected on the federal income Tax Return of Enterprise for the period after the Closing Date, by closing the books of Oiltanking MLP as of the end of the Closing Date.

(c) The Parties shall cooperate fully, and cause their Affiliates to cooperate fully, as and to the extent reasonably requested by the other Party, to accomplish the apportionment of income described pursuant to this Section 5.09 and to promptly respond to requests for the provision of any information or documentation within the knowledge or possession of the other Party as reasonably necessary to facilitate compliance with financial reporting obligations arising under FASB Statement No. 109 (including compliance with Financial Accounting Standards Board Interpretation No. 48), and any audit, litigation or other proceeding (each, a “Tax Proceeding”) with respect to Taxes. Such cooperation shall include access to, the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any Tax Return or Tax Proceeding, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Parties each agree, upon request, to use reasonable efforts to obtain any certificate or other document from any Taxing Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed with respect to the transactions contemplated by this Agreement.

41

(d) The Contributing Parties shall be liable for, shall pay and shall protect, defend, indemnify and hold harmless Enterprise and its Subsidiaries from and against all Damages such parties incur arising from (i) any breach of the representations and warranties contained in Section 3.21 as they relate to Taxes of the General Partner (as if made as of the Closing Date and determined without regard to any Oiltanking Material Adverse Effect, materiality or similar qualifier), (ii) any Taxes of or with respect to the Subject Interests attributable to any taxable period or portion thereof ending on or prior to the Closing Date, (iii) any liability of the General Partner for the Tax of another Person as a result of being (A) a member of an affiliated, consolidated, combined or unitary group prior to the Closing Date or (B) a party to any Tax Sharing Agreement or another contract entered into prior to the Closing Date providing for an obligation to indemnify any other Person for Tax (other than any customary indemnity under credit agreements or other agreements entered into in the ordinary course of business that do not relate primarily to Taxes), and (iv) any Transfer Taxes that the Contributing Parties are obligated to pay as set forth in Section 5.09(a). Enterprise shall be liable for, shall pay and shall protect, defend, indemnify and hold harmless the Contributing Parties from and against all Damages such parties incur arising from (i) any Taxes of or with respect to the Subject Interests attributable to any taxable period or portion thereof beginning after the Closing Date and (ii) any Transfer Taxes that Enterprise is obligated to pay as set forth in Section 5.09(a).

(e) If any claim (an “Indemnified Tax Claim”) is made by any Taxing Authority that, if successful, would result in indemnification of any Party (the “Tax Indemnified Party”) by another Party (the “Tax Indemnifying Party”) under this Section 5.09(e), the Tax Indemnified Party shall promptly, but in no event later than the earlier of (i) 45 days after receipt of notice from the Taxing Authority of such claim or (ii) 15 days prior to the date required for the filing of any protest of such claim, notify the Tax Indemnifying Party in writing of such fact. The Tax Indemnifying Party shall control all decisions with respect to any Tax Proceeding involving an Indemnified Tax Claim and the Tax Indemnified Party shall take such action (including settlement with respect to such Tax Proceeding or the prosecution of such Tax Proceeding to a determination in a court or other tribunal of initial or appellate jurisdiction) in connection with a Tax Proceeding involving an Indemnified Tax Claim as the Tax Indemnifying Party shall reasonably request in writing from time to time, including the selection of counsel and experts and the execution of powers of attorney; provided, however, that (i) within 30 days after the notice required by this Section 5.09(g) has been delivered (or such earlier date that any payment of Taxes with respect to such claim is due but in no event sooner than five days after the Tax Indemnifying Party’s receipt of such notice), the Tax Indemnifying Party requests that such claim be contested, and (ii) if the Tax Indemnified Party is requested by the Tax Indemnifying Party to pay the Tax claimed and sue for a refund, the Tax Indemnifying Party shall have advanced to the Tax Indemnified Party, on an interest-free basis, the amount of such claim. The Tax Indemnified Party shall not make any payment of an Indemnified Tax Claim for at least 30 days (or such shorter period as may be required by Law) after the giving of the notice required by this Section 5.09(g) with respect to such claim, shall give to the Tax Indemnifying Party any information requested related to such claim, and otherwise shall cooperate with the Tax Indemnifying Party in order to contest effectively any such claim.

42

(f) Notwithstanding anything to the contrary herein, to the extent any other provision of this Agreement conflicts with this Section 5.09 with respect to any claims relating to Taxes (including any claims relating to representations respecting Tax matters including Section 3.23 and Section 4.16), this Section 5.09 shall govern. No claim may be made or brought by any Party hereto after the expiration of the applicable survival period unless such claim has been asserted by written notice specifying the details supporting the claim on or prior to the expiration of the applicable survival period. The rights under this Section 5.09 shall survive the Closing until 30 days after the expiration of the statute of limitations (including extensions) applicable to such Tax matter; provided, however, that any claim for indemnification pursuant to Section 5.09(g) shall survive the time at which it would otherwise terminate pursuant to the preceding sentences, if proper notice of such right of indemnity shall have been given to the party against whom such indemnity may be sought prior to such time.

(g) The Parties intend, for U.S. federal income tax purposes, that the contribution of the Subject Interests in exchange for the Consideration shall be treated by the Contributing Parties and Enterprise as (i) a contribution by OTA and OTB Holdco of a portion of the Subject Interests in exchange for the Unit Consideration and, to the maximum extent possible, a reimbursement of certain capital expenditures made by OTA with respect to the Subject Interests satisfying the requirements of Treas. Reg. Section 1.707-4(d) (any such expenditures, “Preformation Capital Expenditures”), in a transaction consistent with the requirements of Section 721 of the Code and (ii) a sale of a portion of the Subject Interests in exchange for the Cash Consideration (other than Cash Consideration equal to the amount of any Preformation Capital Expenditures). The Parties shall not take any position for income Tax purposes that is inconsistent with such treatment, except to the extent that such Party is bound by a final determination that is consistent with such position.

Section 5.10. Employee Matters.

(a) All matters related to the terms of employment to be offered to Business Employees by Enterprise or an Affiliate of Enterprise shall be governed solely by the terms of the Employee Matters Agreement.

(b) Except as expressly set forth in the Employee Matters Agreement, none of Enterprise, any Affiliate of Enterprise, the General Partner or any Oiltanking MLP Entity shall have or assume (i) any OTA Employee Liability, (ii) any liability or obligation to any Business Employee or (iii) any liability or obligation with respect to any OTA Benefit Plan.

(c) Notwithstanding anything to the contrary contained in this Agreement, except as set forth in Section 5.04, (i) no Business Employee shall have any contractual rights (as a third party or otherwise) under the Employee Matters Agreement or any provision of this Agreement, and (ii) nothing in the Employee Matters Agreement or any provision of this Agreement shall be treated as an amendment of, or undertaking or obligation to amend, establish or adopt, any Benefit Plan of Enterprise or any Affiliate of Enterprise with respect to any Business Employee who becomes an employee of Enterprise or an Affiliate of Enterprise as provided in the Employee Matters Agreement.

43

Section 5.11. Board Representation.

(a) Effective as of Closing, the Enterprise General Partner shall appoint Dr. Christian Flach (the “M&B Designee”) as member to the Enterprise Board. M&B shall be entitled to maintain the M&B Designee as a member of the Enterprise Board as long as M&B and its Affiliates beneficially own at least 27,403,676 Enterprise Common Units issued by Enterprise to M&B and its Affiliates pursuant to this Agreement or the Liquidity Option Agreement. In the event that the M&B Designee becomes unable or unwilling to, or for another reason ceases to, serve as a member of the Enterprise Board while M&B is entitled to maintain the M&B Designee, M&B may designate another person reasonably acceptable to the Enterprise Board as replacement of the M&B Designee, and Enterprise General Partner shall appoint, or cause its members to appoint, such person as a member to the Enterprise Board. The M&B Designee shall not be entitled to compensation as a director of the Enterprise General Partner, but the M&B Designee shall be entitled to reimbursement of reasonable travel expenses in connection with attending meetings of the Enterprise Board.

(b) For the avoidance of doubt, (i) the exercise of the “Liquidity Option” under the Liquidity Option Agreement shall not affect M&B’s rights under this Section 5.11 if M&B and its Affiliates continue to beneficially own at least 27,403,676 Enterprise Common Units issued by Enterprise to M&B and its Affiliates pursuant to this Agreement or the Liquidity Option Agreement following such exercise; and (ii) OTA’s Enterprise Common Units shall not cease to be “Registrable Securities” under the Registration Rights Agreement in the event M&B designates another person to replace the M&B Designee.

(c) M&B shall be a third-party beneficiary of this Section 5.11 and shall have the right to enforce its rights hereunder.

Section 5.12. Ancillary Assets.

(a) In connection with the continuation of services to be provided pursuant to the Employee Matters Agreement, each of the Contributing Parties agrees that it will assign and transfer, or cause OTNA or its other affiliates to assign and transfer, to Oiltanking or another entity specified by Enterprise, any and all company vehicles, laptops, desktops, printers, mobile devices and other office assets (the “Devices”) (to the extent owned by the Contributing Parties, OTNA or other affiliates controlled by the Contributing Parties) that are used primarily by any Eligible Employee in rendering the continuation services who becomes an employee of EPCO in accordance with the Employee Matters Agreement; provided, however, that Devices shall not include material office infrastructure such as networking devices and other equipment that are used by Eligible Employees or other employees of OTNA and its affiliates for shared services.

(b) In addition, each of the Contributing Parties agree that it will assign and transfer to Oiltanking or another entity specified by Enterprise any other assets owned by the Contributing Parties that (i) are located on the principal terminal properties of the Oiltanking Entities and used in the business of the Oiltanking Entities or (ii) are primarily used in, or necessary for, the conduct of the business of the Oiltanking Entities; provided, however, that

All covenants and other agreements of the parties contained in this Agreement that, by their terms, are to be performed after the Closing, shall survive the Closing indefinitely or for such shorter period as explicitly specified therein. Notwithstanding the preceding sentences, any breach of representation, warranty, covenant or other agreement in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to this Section 6.01, if notice of the inaccuracy or breach thereof giving rise to such right of indemnity shall have been duly given, in accordance with the procedures and requirements set forth in this ARTICLE 6, to the party against whom such indemnity may be sought prior to such time.

Section 6.02. Indemnification. (a) Effective at and after the Closing, subject to the terms and conditions of this ARTICLE 6, each Contributing Party hereby indemnifies Enterprise and its Affiliates against and agrees to hold each of them harmless from any and all damage, loss, fine, settlement payments, awards, judgments, penalties and expense (including

45

reasonable expenses of investigation and reasonable attorneys’ fees and expenses in connection with any Proceeding whether involving a third party claim or a claim solely between the parties hereto) (“Damages”) actually incurred or suffered by Enterprise or any of its Affiliates arising out of (i) any misrepresentation, breach or inaccuracy of any of the Oiltanking Fundamental Representations or Oiltanking Special Representations or (ii) any breach of covenant or other agreement made or to be performed by each Contributing Party pursuant to this Agreement.

(b) Effective at and after the Closing, subject to the terms and conditions of this ARTICLE 6, Enterprise hereby indemnifies each Contributing Party and its Affiliates against and agrees to hold each of them harmless from any and all Damages actually incurred or suffered by any Contributing Party or any of its Affiliates arising out of (i) any misrepresentation, breach or inaccuracy of any of the Enterprise Fundamental Representations or Enterprise Special Representations, or (ii) any breach of covenant or other agreement made or to be performed by Enterprise pursuant to this Agreement.

Section 6.03. Third Party Claim Procedures. (a) The Person seeking indemnification under Section 6.02 (the “Indemnified Party”) agrees to give prompt notice in writing to the party against whom indemnity is to be sought (the “Indemnifying Party”) of the assertion of any claim or the commencement of any Proceeding by any third party (“Third Party Claim”) in respect of which indemnity may be sought under such Section. Such notice shall set forth in reasonable detail the specifics of such Third Party Claim, the basis for indemnification and the Indemnified Party’s bona fide estimate of the amount of such Third Party Claim (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have actually adversely prejudiced the Indemnifying Party.

(b) The Indemnifying Party shall be entitled to participate in the defense of any Third Party Claim and, subject to the limitations set forth in this Section 6.03, shall be entitled to control and appoint lead counsel for such defense, in each case at its own expense; provided, however, that the Indemnified Party is hereby authorized, prior to the Indemnifying Party’s delivery of a written election to the Indemnified Party of its agreement to defend such Third-Party Claim, to file any motion, answer or other pleading that it shall reasonably deem necessary to protect its interests or those of the Indemnifying Party.

(c) If the Indemnifying Party elects to assume the defense of any such Third Party Claim, it shall within 30 days after receipt of the notice referred to in Section 6.03(a) notify the Indemnified Party in writing of its intent to do so. The Indemnifying Party will have the right to assume control of such defense of the Third Party Claim only for so long as it conducts such defense with reasonable diligence. The Indemnifying Party shall keep the Indemnified Party advised of the status of such Third Party Claim and the defense thereof on a reasonably current basis and shall consider in good faith the recommendations made by the Indemnified Party with respect thereto. If the Indemnifying Party assumes the control of the defense of any Third Party Claim in accordance with the provisions of this Section 6.03, (i) the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement or compromise of such

46

Third Party Claim if the settlement does not release the Indemnified Party and its Affiliates from all liabilities and obligations with respect to such Third Party Claim or the settlement imposes injunctive or other equitable relief against the Indemnified Party or any of its Affiliates; and (ii) the Indemnified Party shall be entitled to participate in the defense of any Third Party Claim and to employ separate counsel of its choice for such purpose. The fees and expenses of such separate counsel shall be paid by the Indemnified Party.

(d) The Indemnified Party shall not settle or compromise any Third Party Claim, or take any corrective or remedial action or enter into an agreed judgment or consent decree with respect thereto, that subjects the Indemnified Party to any criminal liability, requires an admission of guilt or wrongdoing on the part of the Indemnified Party or imposes any continuing obligation on or requires any payment from the Indemnified Party without the prior written consent of the Indemnifying Party (which shall not be unreasonably withheld, conditioned or delayed).

(e) Each party shall reasonably cooperate, and cause their respective controlled Affiliates to reasonably cooperate, in the defense or prosecution of any Third Party Claim and shall furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.

Section 6.04. Direct Claim Procedures. In the event an Indemnified Party has a claim for indemnity under Section 6.02 against an Indemnifying Party that does not involve a Third Party Claim, the Indemnified Party agrees to give prompt notice in writing of such claim to the Indemnifying Party. Such notice shall set forth in reasonable detail the specifics of such claim, the basis for indemnification and the Indemnified Party’s bona fide estimate of the amount of such claim (taking into account the information then available to the Indemnified Party). The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have actually adversely prejudiced the Indemnifying Party. If the Indemnifying Party disputes its indemnity obligation for any Damages with respect to such claim, the parties shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of jurisdiction determined pursuant to Section 7.06.

Section 6.05. Limitation of Damages.

(a) The Indemnifying Party shall not be liable to the Indemnified Party for indemnification under Section 6.02(a)(i) in respect of Oiltanking Special Representations or under Section 6.02(b)(i) in respect of Enterprise Special Representations, as applicable, until the aggregate amount of all Damages in respect of indemnification for Oiltanking Special Representations or Enterprise Special Representations, as applicable, exceeds an amount equal to 1% of the Consideration (the “Deductible”), in which event the Indemnifying Party shall only be required to pay or be liable for Damages in excess of the Deductible. With respect to any indemnification claim under Section 6.02(a)(i) in respect of Oiltanking Special Representations or under Section 6.02(b)(i) in respect of Enterprise Special Representations, as applicable, the Indemnifying Party shall not be liable for any individual or series of related Damages which do not exceed $50,000 (which Damages shall not be counted toward the Deductible).

(b) The aggregate amount of all Damages for which an Indemnifying Party shall be liable pursuant to Section 6.02(a)(i) in respect of Oiltanking Special Representations or under Section 6.02(b)(i) in respect of Enterprise Special Representations, as applicable, shall not exceed an amount equal to 10% of the Consideration.

47

Section 6.06. Calculation of Damages. (a) The amount of any Damages payable under Section 6.02 by the Indemnifying Party shall be net of any amounts actually recovered by the Indemnified Party under applicable insurance policies or from any other Person alleged to be responsible therefor. If the Indemnified Party receives any amounts under applicable insurance policies, or from any other Person alleged to be responsible for any Damages, subsequent to an indemnification payment by the Indemnifying Party, then such Indemnified Party shall promptly reimburse the Indemnifying Party for any payment made or expense incurred by such Indemnifying Party in connection with providing such indemnification payment up to the amount received by the Indemnified Party, net of any reasonable expenses incurred by such Indemnified Party in collecting such amount.

(b) The Indemnifying Party shall not be liable under Section 6.02 for any punitive, special, indirect, consequential, remote or speculative Damages of any kind or nature or (ii) Damages for lost profits, except with respect to Damages for lost profits, to the extent a court of competent jurisdiction determined that lost profits is the appropriate measure of direct damages with respect to the matters giving rise to the claim for Damages; provided, that nothing herein shall prevent an Indemnified Party from recovering all components of awards against them in Third Party Claims for which recovery is provided in this ARTICLE 6.

(c) Each Indemnified Party must take commercially reasonable efforts to mitigate in accordance with Applicable Law any Damages for which such Indemnified Party seeks indemnification under this Agreement. If such Indemnified Party mitigates its Damages after the Indemnifying Party has paid the Indemnified Party under any indemnification provision of this Agreement in respect of that Damage, the Indemnified Party must notify the Indemnifying Party and pay to the Indemnifying Party the extent of the value of the benefit to the Indemnified Party of that mitigation (less the Indemnified Party’s reasonable costs of mitigation) promptly after the benefit is received.

(d) Each Indemnified Party shall use commercially reasonable efforts to seek recovery and collect any amounts available under insurance coverage, or from any other Person alleged to be responsible, for any Damages payable under Section 6.02. To the extent recovery and collection is obtained, the amount of any Damages with respect to such indemnification claim will be reduced accordingly.

Section 6.07. Assignment of Claims. If the Indemnified Party receives any payment from an Indemnifying Party in respect of any Damages pursuant to Section 6.02 and it is reasonably likely that the Indemnified Party could have recovered all or a part of such Damages from a Third Party (a “Potential Contributor”) based on the underlying claim

48

asserted against the Indemnifying Party, to the extent permitted under Applicable Law, the Indemnified Party shall assign its rights to proceeds and other rights against the Potential Contributor as are necessary to permit the Indemnifying Party to recover from the Potential Contributor the amount of such payment.

Section 6.08. Exclusivity. After the Closing, except for any claim arising in respect of fraud, Section 5.09 and Section 6.02 will provide the exclusive remedies for any misrepresentation or breach of warranty, or of covenant or other agreement or other claim arising out of this Agreement or the transactions contemplated hereby (other than equitable remedies as they relate to breaches of covenants or other agreements contained herein to the extent such covenants or agreements are to be performed after Closing).

Section 6.09. Purchase Price Adjustment. Any amount paid by any Contributing Party or Enterprise under this ARTICLE 6 will be treated as an adjustment to the Cash Consideration.

Process in any such Proceeding may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court. Without limiting the foregoing, each party agrees that service of process on such party as provided in Section 7.01 shall be deemed effective service of process on such party.

Section 7.07. Waiver of Jury Trial.

Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 7.11. Disclosure Schedules. The Contributing Parties have set forth information on the Disclosure Schedules in a Section thereof that corresponds to the Section of this Agreement to which it relates. A matter set forth in one Section of a Schedule need not be set forth in any other Section so long as its relevance to such other Section of the Schedule or Section of the Agreement is reasonably apparent on the face of the information disclosed therein to the Person to which such disclosure is being made. The parties acknowledge and agree that (a) the Disclosure Schedules may include certain items and information solely for informational purposes for the convenience of Enterprise and (b) the disclosure by the Contributing Parties of any matter in the Disclosure Schedules shall not be deemed to constitute an acknowledgment by the Contributing Parties that the matter is required to be disclosed by the terms of this Agreement or that the matter is material.
