ARTICLE VI TITLE MATTERS

50

6.1 General Disclaimer of Title Representations and Warranties. Except for the warranty of title set forth in Section 6.2, Sellers make no warranty or representation, express, implied, statutory or otherwise, with respect to the Company’s or the Entities’ title to any of the Company Real Property and Buyer hereby acknowledges and agrees that, except for cases of fraud or intentional misrepresentation, Buyer’s sole remedy for any Title Defect, with respect to any of the Company Real Property, shall be pursuant to the warranty of title set forth in Section 6.2.

6.2 Warranty of Title. Sellers warrant title to property set forth on Schedule 6.2 unto Buyer against every Person whomsoever lawfully claiming or to claim the same or any part thereof, subject, however, to the Permitted Encumbrances; provided, however, that, except with respect to any liability of Sellers with respect to a breach of such warranty (each a “Warranty Breach”) as the result of a Claim asserted in writing by Buyer to Sellers in accordance with Section 6.3 on or before the expiration of the Survival Period, such warranty shall cease and terminate at the end of such Survival Period. Said warranty of title shall be subject to the further limitations and provisions of this ARTICLE VI.

6.3 Recovery on Warranty. During the period commencing as of the Execution Date and ending on the first anniversary thereof (the “Survival Period”), Buyer shall furnish to Sellers a Warranty Breach Notice setting forth any matters which Buyer intends to assert as Warranty Breaches. Sellers shall have a reasonable opportunity, but not the obligation, to cure any Warranty Breach asserted by Buyer pursuant to this Section 6.3. Sellers shall notify Buyer of any intention to cure any Warranty Breach within ten (10) days of receipt of a Warranty Breach Notice or Sellers shall be deemed to have waived the right to cure such Warranty Breach. Buyer agrees to reasonably cooperate and, from and after the Execution Date, to cause the Company and the Entities to reasonably cooperate, with any attempt by Sellers to cure any such Warranty Breach.

6.4 Waiver of Title Defects. For all purposes of this Agreement and notwithstanding anything herein to the contrary (a) the term Warranty Breach shall include without limitation any title-related matter that materially prejudices Buyer’s ability to use and operate the property set forth on Schedule 6.2 as currently used or as currently contemplated to be used and (b) Buyer shall be deemed to have waived, and Sellers shall have no further liability for, any Warranty Breach that Buyer fails to assert by a Warranty Breach Notice given to Sellers on or before the expiration of the Survival Period. Nothing herein shall be construed as a waiver of any claim arising from an intentional non-disclosure of any defect in title, including a Title Defect.

6.5 Title Dispute Resolution.

(h) Sellers and Buyer shall attempt to agree on all (i) Claims of Warranty Breaches and (ii) the related Warranty Breach Amounts, in each case, prior to the expiration of the Survival Period. If Sellers and Buyer are unable to agree prior to the expiration of the Survival Period, the Warranty Breaches and Warranty Breach Amounts in dispute shall be exclusively and finally resolved pursuant to this Section 6.5(a) (each, a “Title Dispute”).

(i) There shall be a single arbitrator, who shall be a title attorney with at least fifteen (15) years’ experience in pipeline and gathering system title matters involving properties in the regional area in which the Warranty Breach Property is located, as selected by mutual agreement

51

of Buyer and Sellers within twenty (20) Days after the end of the Survival Period, and absent such agreement, by the Houston office of the AAA (the “Title Arbitrator”).

(j) The arbitration proceeding shall be held in Houston, Texas, and shall be conducted in accordance with the Commercial Arbitration Rules of the AAA, to the extent such rules do not conflict with the terms of this Agreement. The Title Arbitrator’s determination of the Title Dispute shall be made within twenty (20) days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his or her determination, the Title Arbitrator shall be bound by the rules set forth in this ARTICLE VI, and, subject to the foregoing, may consider such other matters as, in the opinion of the Title Arbitrator, are necessary to make a proper determination. The Title Arbitrator, however, may not attribute to any Warranty Breach a greater Warranty Breach Amount than the Warranty Breach Amount claimed by Buyer in the applicable Warranty Breach Notice nor a lesser Warranty Breach Amount than the Warranty Breach Amount admitted to by Sellers.

(k) Sellers and Buyer shall each bear their own legal fees and other costs of presenting its case. Sellers bear fifty percent (50%) and Buyer shall bear fifty percent (50%) of the costs and expenses of the Title Arbitrator.

(l) Within ten (10) days after (i) the Title Arbitrator delivers written notice to Buyer and Sellers of his or her decision with respect to a Title Dispute, if such decision determines that the Warranty Breach claimed by Buyer in the applicable Warranty Breach Notice did occur or (ii) the Parties agree that any amount is payable to Buyer pursuant to this ARTICLE VI, Buyer shall provide the Escrow Agent notice of such determination and Escrow Agent shall deliver to Buyer (A) an amount equal to the amount awarded by the Title Arbitrator or otherwise agreed by the Parties, by wire transfer of immediately available funds to a bank account designated by Buyer, which amount will be paid with cash from dividends, earnings or other distributions on Common Units in the Escrow Fund and (B) to the extent there is not sufficient cash from dividends, earnings or other distributions on Common Units in the Escrow Fund to pay the required amount, by delivery of the number of Consideration Units held in the Escrow Fund equal to (x) the difference between (1) the amount awarded to Buyer by the Title Arbitrator and (2) the amount distributed pursuant to clause (A) of this sentence, divided by (y) the Market Price.

(m) Notwithstanding anything to the contrary, in no event shall the aggregate liability of Sellers pursuant to this ARTICLE VI, aggregated with all liability of Sellers pursuant to ARTICLE VIII, exceed Forty Million Dollars ($40,000,000); provided, however, that no Claims of Warranty Breaches arising out of fraud or intentional misrepresentation shall be limited by this Section 6.5(f).

57

Indemnified Party pursuant to this Agreement (the “Non-Settlement Indemnification Amount”), in which case the liability of the Indemnifying Party in connection with such Third Person Claim will be limited to the Non-Settlement Indemnification Amount. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by an Indemnified Party, and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

(g) If the Indemnifying Party is obligated to defend and indemnify the Indemnified Party, and (i) the Parties have a conflict of interest with respect to any such Third Person Claim, (ii) there are legal defenses available to an Indemnified Party that are different or in addition to those available to the Indemnifying Party or (iii) the Indemnifying Party fails to diligently defend such Third Person Claim, then the Indemnified Party may, in its sole discretion, separately and independently contest and defend such Third Person Claim, and the Indemnifying Party shall be bound by the result obtained with respect thereto by the Indemnified Party and shall be responsible for all out of pocket costs incurred in connection therewith (including legal fees and expenses).

(h) If the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against a Third Person Claim, the Indemnifying Party shall have the right to defend all appropriate Proceedings, with counsel of its own choosing and reasonably acceptable to the Indemnified Party, and such Proceedings shall be promptly settled or prosecuted by the Indemnifying Party to a final conclusion. If the Indemnified Party desires to participate in any such defense or settlement it may do so at its sole cost and expense (subject to Section 8.4(e)). If the Indemnified Party joins in any such Third Person Claim, the Indemnifying Party shall nevertheless have full authority to determine all action to be taken with respect thereto, subject to the last sentence of Section 8.4(g) and all of Section 8.4(h); provided, however, that the Indemnified Party shall have full authority and the right to direct the defense of any Third Person Claim that seeks an injunction or other equitable relief against the Indemnified Party, at the cost and expense of the Indemnifying Party.

(i) Each Party agrees to cooperate with the other Party and its counsel in contesting any Third Person Claim and in making any counterclaim against the Third Person asserting the Third Person Claim, or any cross-complaint against any Person. No Third Person Claim may be settled or otherwise compromised without the prior written consent of the Indemnified Party unless such settlement (i) includes a provision whereby the plaintiff or claimant in the matter releases the Indemnified Party from all liability with respect to such Third Person Claim, or (ii) would not restrict the Indemnified Party’s ability to conduct its business in the ordinary course.

(j) Notwithstanding anything to the contrary in this Agreement, the Indemnifying Party will not be permitted to settle, compromise, take any corrective or remedial action or enter into an agreed judgment or consent decree, in each case, that (i) subjects the Indemnified Party to any criminal liability, (ii) requires an admission of guilt or wrongdoing on the part of the Indemnified Party or (iii) requires any payment from the Indemnified Party without the Indemnified Party’s prior written consent, such consent not to be unreasonably withheld, conditioned or delayed.

(k) At any time after the commencement of defense of any Third Person Claim, the Indemnifying Party may request the Indemnified Party to agree in writing to the abandonment

58

of such contest or to the settlement, payment or compromise by the Indemnifying Party of the asserted Third Person Claim, but only if the Indemnifying Party agrees in writing to be solely liable for such Third Person Claim; whereupon such action shall be taken unless the Indemnified Party determines that the contest should be continued and notifies the Indemnifying Party in writing within fifteen (15) days of such request from the Indemnifying Party. In the event that the Indemnified Party determines that the contest should be continued, the amount for which the Indemnifying Party would otherwise be liable hereunder shall not exceed the amount which the Indemnifying Party had agreed to pay to compromise such Third Person Claim; provided that, the other Person to the contested Third Person Claim had agreed in writing to accept such amount in payment or compromise of the Third Person Claim as of the time the Indemnifying Party made its request therefor to the Indemnified Party, and further provided that, under such proposed compromise, the Indemnified Party would be fully and completely released from any further liability or obligation with respect to the matters which are the subject of such contested Third Person Claim.

(l) With respect to any Claim made directly by an Indemnified Party to an Indemnifying Party and not involving a Third Party Claim (a “Direct Claim”), the Indemnified Party shall assert such Claim by delivering a Claim Notice to the Indemnifying Party reasonably promptly after becoming aware of such Direct Claim and the Indemnifying Party shall then have thirty (30) days to respond in writing to the Indemnified Party after its receipt of the Claim Notice. If the Indemnifying Party does not so respond within the initial thirty (30) day period, the Indemnifying Party shall be deemed to have rejected such Claim, in which case the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement. The Indemnified Party shall allow the Indemnifying Party and its Representatives and other professional advisors to investigate the matter or circumstance alleged to give rise to the Third Party Claim, and whether and to what extent any amount is payable in respect of such Third Party Claim, and the Indemnified Party shall assist the Indemnifying Party’s investigation by giving such reasonable information and assistance (including access to the Indemnified Party’s premises and personnel and the right to examine and copy any accounts, documents or records) as the Indemnifying Party or any of its professional advisors may reasonably request. Any failure by the Indemnified Party to give reasonably prompt written notice to the Indemnifying Party of a Direct Claim shall not relieve the Indemnifying Party of its indemnification obligations unless, and then only to the extent that, the Indemnifying Party is prejudiced by reason of such failure.

(m) Once a Loss is agreed to by the Indemnifying Party or finally adjudicated to be payable pursuant to this ARTICLE VIII, the Indemnifying Party shall satisfy its obligations within fifteen (15) days of such agreement or such final, non-appealable adjudication by (i) if Buyer is the Indemnifying Party, wire transfer of immediately available funds and (ii) if Sellers are the Indemnifying Party, by causing the Escrow Agent to deliver to Buyer (A) an amount equal to the agreed-upon or finally adjudicated Loss by wire transfer of immediately available funds, which amount will be paid with cash from dividends, earnings or other distributions on Common Units in the Escrow Fund and (B) to the extent there is not sufficient cash from dividends, earnings or other distributions on Common Units in the Escrow Fund to fulfill the required amount, by delivery of the number of Common Units held in the Escrow Fund equal to (x) the difference between (I) the agreed-upon or finally adjudicated Loss and (II) the amount distributed pursuant to clause (A)

59

of this sentence, if any, divided by (y) the Market Price; provided, however, that Sellers shall pay all Losses adjudicated to be payable pursuant to this ARTICLE VIII arising pursuant to Sections 8.2(a)(iii) and 8.2(a)(iv) by wire transfer to Buyer of immediately available funds. The Parties agree that if the Indemnifying Party does not make full payment of any such obligations, subject to the limitations set forth in Sections 8.3(b)(ii), 8.3(b)(iii), 8.3(b)(iv) and 8.6(a), if applicable, within such fifteen (15) day period, any amount payable shall accrue interest from and including the date of agreement of the Indemnifying Party or final, non-appealable adjudication, at the Interest Rate.

8.5 Effect of Investigation. The representations, warranties and covenants of the Indemnifying Party, and the Indemnified Party’s right to indemnification with respect thereto, shall not be affected or deemed waived by reason of any investigation made by or on behalf of the Indemnified Party (including by any of its Representatives) or by reason of the fact that the Indemnified Party or any of its Representatives knew or should have known that any such representation or warranty is, was or might be inaccurate.

8.6 Escrow Fund.

(c) As a source of payment for the indemnities provided by Sellers pursuant to this Agreement, the Escrow Unit Amount shall be deposited by Buyer with the Escrow Agent, such deposit to be governed by the terms set forth herein and in the Escrow Agreement. Notwithstanding anything to the contrary contained in this Agreement, Buyer acknowledges and agrees that, the Escrow Fund shall be the sole and exclusive source of funds for satisfaction of all claims by Buyer or Buyer Indemnitees for Losses pursuant to ARTICLE VI and ARTICLE VIII other than Losses arising out of (i) a violation of a Fundamental Representation, (ii) the breach of any covenant, (iii) fraud or intentional misrepresentation, (iv) Sections 8.2(a)(iii) and 8.2(a)(iv).

(d) Subject to the following requirements, the Escrow Fund shall be in existence on the Execution Date and shall terminate on the later of: (i) the Second Release Date, or (ii) the Commercial Completion Date (the period of time from the Execution Date through and including such termination date is referred to herein as the “Escrow Period”); provided, however, that the Escrow Cash Amount shall be released prior to the termination of the Escrow Period pursuant to Section 2.5(d); provided, further, that: (i) the First Release Units shall be released on the First Release Date, and (ii) the Second Release Units shall be released on the Second Release Date. Notwithstanding the previous sentence, (i) to the extent that one or more Claim Notices has been delivered to Sellers but not resolved as of the First Release Date or the Second Release Date (as applicable, the “Relevant Release Date”), a number of First Release Units or Second Release Units (as applicable, the “Relevant Release Units”) equal to (x) the amount of Losses that are the subject of the Claim Notice and which exceed the Escrow Unit Earnings on the Relevant Release Units divided by (y) the Market Price shall remain in the Escrow Fund beyond the Relevant Release Date and shall be released upon the resolution of such claim (such calculation method, the “Interim Holdback Calculation Method”), and (ii) to the extent that one or more Claim Notices (an “Ongoing Claim Notice”) has been delivered to Sellers but not resolved as of the last day of the Escrow Period, (x) Escrow Unit Earnings equal to the amount of Losses that are the subject of the Ongoing Claim Notice and, (y) to the extent the Escrow Unit Earnings in the Escrow Fund as of the last day of the Escrow Period are less than the amount of Losses that are the subject of the Ongoing Claim Notice,

60

a number of Common Units equal to (1) the amount of Losses that are the subject of the Ongoing Claim Notice and which exceed the Escrow Unit Earnings in the Escrow Fund as of the last day of the Escrow Period divided by (2) the Market Price (such calculation method, the “Final Holdback Calculation Method”), shall remain in the Escrow Fund beyond the last day of the Escrow Period and shall be released upon the resolution of such claim. Should the Second Release Date be the same date as the last day of the Escrow Period, the Final Holdback Calculation Method and not the Interim Calculation Method, will be used to calculate the amount of Consideration Units to remain in the Escrow Fund following the Second Release Date.

8.7 Exclusive Remedy. EXCEPT FOR CASES OF FRAUD AND INTENTIONAL MISREPRESENTATION, AS BETWEEN THE BUYER INDEMNITEES AND THE SELLER INDEMNITEES, AFTER CLOSING (A) THE EXPRESS INDEMNIFICATION PROVISIONS SET FORTH IN THIS AGREEMENT WILL BE THE SOLE AND EXCLUSIVE RIGHTS, OBLIGATIONS AND REMEDIES OF THE PARTIES (OTHER THAN THE FINAL SETTLEMENT PURSUANT TO SECTIONS 2.3 THROUGH 2.5 AND 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 THE CLOSING) AND (B) NEITHER PARTY NOR ANY OF ITS RESPECTIVE SUCCESSORS OR ASSIGNS SHALL HAVE ANY RIGHTS AGAINST THE OTHER PARTY OR ITS AFFILIATES AS TO THE SUBJECT MATTER CONTAINED IN THIS AGREEMENT OTHER THAN AS IS EXPRESSLY PROVIDED IN THIS AGREEMENT.

8.8 Negligence and Strict Liability Waiver. WITHOUT LIMITING OR ENLARGING THE SCOPE OF THE INDEMNIFICATION OBLIGATIONS SET FORTH IN THIS AGREEMENT AND THE TRANSACTION DOCUMENTS, AN INDEMNIFIED PARTY SHALL BE ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT IN ACCORDANCE WITH THE TERMS HEREOF, REGARDLESS OF WHETHER THE LOSS OR CLAIM GIVING RISE TO SUCH INDEMNIFICATION OBLIGATION IS THE RESULT OF THE SOLE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY, OR VIOLATION OF ANY LAW OF OR BY SUCH INDEMNIFIED PARTY.

8.9 Limitation on Damages. IN NO EVENT SHALL EITHER SELLERS OR BUYER BE LIABLE TO THE OTHER, OR TO THE OTHER’S INDEMNITEES, UNDER THIS AGREEMENT OR ANY OF THE TRANSACTION DOCUMENTS FOR ANY EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, ANY DAMAGES FOR LOST PROFITS, ANY DAMAGES FOR DIMINUTION OF VALUE OR DAMAGES BASED ON ANY TYPE OF MULTIPLE; PROVIDED, HOWEVER, THAT IF ANY OF THE SELLER INDEMNITEES OR BUYER INDEMNITEES IS HELD LIABLE TO A THIRD PERSON FOR ANY SUCH DAMAGES AND THE INDEMNITOR IS OBLIGATED TO INDEMNIFY SUCH SELLER INDEMNITEES OR BUYER INDEMNITEES FOR THE MATTER THAT GAVE RISE TO SUCH DAMAGES, THE INDEMNITOR SHALL BE LIABLE FOR, AND OBLIGATED TO REIMBURSE SUCH INDEMNITEES FOR SUCH DAMAGES.

61

8.10 Bold and/or Capitalized Letters. THE PARTIES AGREE THAT THE BOLD AND/OR CAPITALIZED LETTERS IN THIS AGREEMENT CONSTITUTE CONSPICUOUS LEGENDS.

8.11 Capital Expenditure Indemnification Procedures. On or before thirty (30) days prior to the Commercial Completion Date, Buyer shall submit to Sellers a written calculation (the “CapEx Calculation”) of the total amount of capital expenditures required to be made as of such date in order to complete the construction of, and place into service, facilities which are sufficient on a commercially reasonable basis to provide the services specifically contemplated by the line item descriptions set forth on Schedule 1.1(b). Any disagreements the Parties may have with regard to the amount of such capital expenditures shall be resolved utilizing the procedures set forth in Section 8.4(j).

ARTICLE IX MISCELLANEOUS PROVISIONS

9.1 Expenses. Each of Sellers and Buyer will bear its own costs and expenses (including legal fees and expenses) incurred in connection with the negotiation of this Agreement and the transactions contemplated hereby.

9.2 Further Assurances. From time to time, and without further consideration, each Party will, and will cause its Affiliates to, execute and deliver to the other Party such documents, instruments and conveyances and take such actions and provide such further assurances as the other Party may reasonably request in order to more effectively implement the provisions hereof and effect the transactions contemplated by this Agreement and the other Transaction Documents.

9.3 Apportionment of Taxes; Transfer Taxes; and Recording Fees; Tax Treatment.

(n) In the case of Taxes that are payable with respect to any Straddle Period, for the Company or the Entities the amount of any such Tax that is attributable to the portion of the period ending on the Execution Date shall be a Seller Tax and shall be:

(vi) in the case of Taxes that are either (A) based upon or related to income or receipts, (B) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible) or (C) franchise or doing business Taxes, deemed equal to the amount that would be payable if the Tax period ended with (and included) the Execution Date; provided that exemptions, allowances or deductions that are calculated on an annual basis (including depreciation and amortization deductions) shall be allocated between the period ending on and including the Execution Date and the period beginning after the Execution Date in proportion to the number of days in each period; and

(vii) in the case of all Taxes not described in 9.3(a)(i), deemed to be the amount of such Taxes for the entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period), multiplied by a fraction the numerator of which is the number of calendar days in the portion

62

of the period ending on and including the Execution Date and the denominator of which is the number of calendar days in the entire period.

(o) To the extent that Seller Taxes are known as of the Execution Date, such Seller Taxes shall reduce the Closing Cash Consideration Amount. In all other cases, Buyer shall prepare the Tax Returns for the Company and the Entities in a manner consistent with the prior practices of the respective entities and, except as otherwise required by Law, shall deliver such Tax Returns, within a reasonable period of time prior to the date such returns are required to be filed, to the Sellers for their review and comment prior to the filing thereof. Sellers shall pay to Buyer, within fifteen (15) days of written demand from Buyer, the amount of any Seller Tax to the extent not taken into account as a reduction in the amount payable to Sellers under the first sentence of this Section 9.3(b) and Sections 2.3 through 2.5.

(p) Subject to the apportionment of provisions of Sections 9.3(a)(ii) and 9.3(b), Buyer agrees to assume liability for the payment of all property Taxes for the year of Closing and subsequent years and Sellers hereby agree to retain liability for the payment of all property Taxes for years prior to the year of Closing. If Buyer receives a statement or invoice concerning Taxes and such statement relates to properties in addition to the Assets, the Parties will cooperate in good faith to apportion and timely pay such property Taxes.

(q) Sellers and Buyer believe that this purchase and sale of the Assets is exempt from or is otherwise not subject to any and all sales, use, transfer, or similar Taxes. If any such sales, transfer, use or similar Taxes are due or should hereafter become due (including penalty and interest thereon) by reason of this transaction, Buyer and Sellers shall each be responsible for one-half of such Taxes.

(r) Buyer and Sellers shall cooperate fully as and to the extent reasonably requested by the other Party in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes (each, a “Tax Proceeding”) imposed on or with respect to the Assets or the operations or activities of the Company or the Entities. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such 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.

(s) For U.S. federal income tax and any applicable state and local Tax purposes, the sale and purchase of the Interests hereunder shall be treated (i) in part as a sale by the Sellers of Interests (interests in a federal tax partnership) in a transaction subject to Section 707(a)(2)(B) of the Code and the applicable Treasury Regulations promulgated thereunder and (ii) in part as a contribution of Interests to the capital of Buyer Parent in exchange for an interest therein under Section 721 of the Code. A portion of the Base Purchase Price may be treated as a reimbursement of preformation expenditures as set forth in Treasury Regulations § 1.707-4(d), and the Parties shall not take any steps that would impair the ability of Sellers to report the full amount of reimbursement of preformation expenditures that they may be entitled to as set forth in the Treasury Regulations.

63

(t) If requested by Buyer, Sellers shall cause Costar Mesquite and Transtar to each make an election under Section 754 of the Code for its Tax year ending on, or that includes, the Execution Date. The Parties shall take all actions necessary to cause each of Costar Mesquite and Transtar to make such election.

9.4 Assignment. The provisions of this Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective successors and assigns, provided that neither Party may assign this Agreement or any of its rights or obligations arising hereunder without the prior written consent of the other Party.

9.5 Entire Agreement, Amendments and Waiver. This Agreement, together with the Transaction Documents and all certificates, documents, instruments and writings that are delivered pursuant hereto and thereto contain the entire understanding of the Parties with respect to the transactions contemplated hereby and supersede all prior agreements, arrangements and understandings relating to the subject matter hereof; provided that the Confidentiality Agreement (which is hereby ratified) shall terminate upon Closing. This Agreement may be amended, superseded or canceled only by a written instrument duly executed by the Parties. Any of the terms of this Agreement and any condition to a Party’s obligations hereunder may be waived only in a signed writing by that Party specifically stating that it waives a term or condition hereof. No waiver by either Party of any one or more conditions or defaults by the other in performance of any of the provisions of this Agreement shall operate or be construed as a waiver of any future conditions or defaults, whether of a like or different character, nor shall the waiver constitute a continuing waiver unless otherwise expressly provided.

9.6 Severability. Each portion of this Agreement is intended to be severable. If any term or provision hereof is illegal or invalid for any reason whatsoever, such illegality or invalidity shall not affect the validity of the remainder of this Agreement.

9.7 Counterparts; Electronic Delivery. This Agreement may be executed simultaneously in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Any counterpart signature page that is delivered via facsimile, electronic mail or other electronic means shall have the same force and effect as an original counterpart signature page.

9.8 Governing Law and Dispute Resolution.

(d) Governing Law. This Agreement shall be governed by, enforced in accordance with, and interpreted under, the Laws of the State of Delaware, without reference to conflicts of Laws principles.

(e) Negotiation. In the event of any dispute, the Parties shall promptly seek to resolve any such dispute by negotiations between senior executives of the Parties who have authority to settle the dispute. When a Party believes there is a dispute under this Agreement that Party will promptly give the other Party written notice of the dispute. Within thirty (30) days after receipt of such notice, the receiving Party shall submit to the other a written response. Both the notice and response shall include (i) a statement of each Party’s position and a summary of the evidence and

64

arguments supporting such position, and (ii) the name, title, fax number, and telephone number of the executive or executives who will represent that Party. If the dispute involves a Claim arising out of the actions of any Person not a signatory to this Agreement, the receiving Party shall have such additional time as necessary, not to exceed an additional thirty (30) days, to investigate the dispute before submitting a written response. The executives shall meet at a mutually acceptable time and place within fifteen (15) days after the date of the response and thereafter as often as they reasonably deem necessary to exchange relevant information and to attempt to resolve the dispute.

(f) Failure to Resolve. If the dispute has not been resolved within sixty (60) days after the date of the response given pursuant to Section 9.8(b) above, or such additional time, if any, that the Parties mutually agree to in writing, or if the Party receiving such notice denies the applicability of the provisions of Section 9.8(b) or otherwise refuses to participate under the provisions of Section 9.8(b), either Party may initiate legal proceedings to enforce its rights under this Agreement.

(g) The provisions of Sections 9.8(b) and 9.8(c) shall not apply to disputes governed by Sections 2.3 through 2.5 or ARTICLE VI.

(h) Jurisdiction. ANY LEGAL SUIT, ACTION OR PROCEEDING ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY MAY BE INSTITUTED IN THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA OR THE COURTS OF THE STATE OF TEXAS IN EACH CASE LOCATED IN THE CITY OF HOUSTON AND COUNTY OF XXXXXX, AND EACH PARTY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF SUCH COURTS IN ANY SUCH SUIT, ACTION OR PROCEEDING. SERVICE OF PROCESS, SUMMONS, NOTICE OR OTHER DOCUMENT BY MAIL TO SUCH PARTY’S ADDRESS SET FORTH HEREIN SHALL BE EFFECTIVE SERVICE OF PROCESS FOR ANY SUIT, ACTION OR OTHER PROCEEDING BROUGHT IN ANY SUCH COURT. THE PARTIES IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY OBJECTION TO THE LAYING OF VENUE OF ANY SUIT, ACTION OR ANY PROCEEDING IN SUCH COURTS AND IRREVOCABLY WAIVE AND AGREE NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

(i) Waiver of Jury Trial. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT OR THE OTHER TRANSACTION DOCUMENTS IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL

65

ACTION, (ii) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (iv) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.8(f).
