ARTICLE VII
TAX MATTERS

     Section 7.1 Tax Returns.

          (a) Through the Closing, each of SE Transmission and MLP GP shall cause Saltville LLC to continue either to be treated as a partnership or disregarded as an entity separate from its owner for federal income tax purposes pursuant to Treasury Regulation Section  ###-###-####-3(b)(1), and the operations of each of the Saltville Companies through the Effective Time shall be reflected on the consolidated federal income Tax Return of Spectra Energy Corp. The income of the Saltville Companies will be apportioned to the period up to and including the Effective Time, and the period after the Effective Time, by closing the books of the Saltville Companies as of the Effective Time.

          (b) Except as provided in Section 7.1(d) for ad valorem Taxes, with respect to any Tax Return of any Saltville Company covering a taxable period ending on or before the Effective Time that is required to be filed after the Effective Time, SE Transmission shall cause such Tax Return to be prepared and shall cause to be included in such Tax Return all Tax items required to be included therein. Not later than 15 days prior to the due date of each such Tax Return, SE Transmission shall deliver a copy of such Tax Return to Spectra MLP together with a statement of the difference, if any, of the amount of Tax shown due on such Tax Return over the amount set up as a liability for such Tax (for the period through the Effective Time) in the Final Net Working Capital. If the Tax shown on the Tax Return exceeds the amount set up as a liability for the Tax (for the period through the Effective Time) in the Final Net Working Capital, not later than the due date of such Tax Return, each of SE Transmission and MLP GP shall pay to Spectra MLP its share of such amount of such excess. If the amount set up as a liability for

the Tax (for the period through the Effective Time) in the Final Net Working Capital exceeds the Tax shown on the Tax Return, not later than the due date of such Tax Return, Spectra MLP shall pay to SE Transmission and MLP GP in proportion to such Party’s ownership of the Saltville Companies prior to this Agreement the amount of such excess. Spectra MLP shall cause such Saltville Company to file the Tax Return and timely pay the Taxes shown due on such Tax Return.

          (c) With respect to any Tax Return of a Saltville Company covering a taxable period beginning on or before the Effective Time and ending after the Effective Time that is required to be filed after the Effective Time, Spectra MLP shall cause such Tax Return to be prepared and shall cause to be included in such Tax Return all Tax items required to be included therein. Spectra MLP shall determine (by an interim closing of the books as of the Effective Time except for franchise Taxes based solely on capital and ad valorem Taxes which shall be prorated on a daily basis) the Tax which would have been due with respect to the period covered by such Tax Return if such taxable period ended on the Effective Time (the “Pre-Closing Tax”). For this purpose, any franchise Tax paid or payable with respect to any Saltville Company shall be allocated to the taxable period for which payment of the Tax provides the right to engage in business, regardless of the taxable period during which the income, operations, assets or capital comprising the base of such Tax is measured. Not later than 15 days prior to the due date of each such Tax Return, Spectra MLP shall deliver a copy of such Tax Return to each SE Transmission and MLP GP for their review. Spectra MLP shall make all reasonable changes to such Tax Return as requested by each of SE Transmission and MLP GP not later than ten days prior to the due date of such Tax Return. Not later than the due date of the Tax Return, either (i) each of SE Transmission and MLP GP shall pay to Spectra MLP their share of the excess, if any, of the Pre-Closing Tax over the amount set up as a liability for the Pre-Closing Tax in the Final Net Working Capital, or (ii) Spectra MLP shall pay to SE Transmission or MLP GP in proportion to such Party’s ownership of Saltville LLC prior to this Agreement the excess, if any, of the amount set up as a liability for the Pre-Closing Tax in the Final Net Working Capital over the Pre-Closing Tax. Spectra MLP shall cause such Saltville Company to file the Tax Return and timely pay the Taxes shown due on such Tax Return.

          (d) Ad valorem Taxes relating to the Saltville Companies for any tax year that includes periods prior to the Closing Date shall be prorated on a daily basis between Spectra MLP on the one hand and SE Transmission on the other hand, with SE Transmission responsible for the prorated portion of such Taxes for the period up to and including the Closing Date and Spectra MLP responsible for the prorated portion of such Taxes after the Closing Date. The Party that receives the ad valorem Tax billing (the “Billed Party”) shall provide a copy of such billing to the other Party together with a calculation of the prorated ad valorem Taxes owed by each Party. The Party that did not receive the ad valorem Tax billing shall pay its prorated portion of the ad valorem Taxes to the Billed Party prior to the due date of such Taxes and the Billed Party shall be responsible for the timely payment of the ad valorem Taxes to the taxing authorities.

          (e) Any Tax Return prepared pursuant to the provisions of this Section 7.1 shall be prepared in a manner consistent with practices followed in prior years with respect to similar Tax Returns, except as otherwise required by Law or fact. Any dispute arising pursuant

to the provisions of Section 7.1(b) or Section 7.1(c) shall be resolved pursuant to procedures comparable to the procedures applicable under Sections 2.4.

          (f) Spectra MLP, MLP GP and SE Transmission shall cooperate fully, and Spectra MLP shall cause each of the Saltville Companies to cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the preparation and filing of Tax Returns pursuant to this Section 7.1 (and Section 7.5), 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 without limitation, 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 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. SE Transmission will, MLP GP will and Spectra MLP will and will cause the Saltville Companies to, (i) retain all books and records with respect to Tax matters pertinent to the Saltville Companies relating to any taxable period beginning before the Effective Time until the later of six years after the Effective Time or the expiration of the applicable statute of limitations of the respective taxable periods (including any extensions thereof), and to abide by all record retention agreements entered into with any Tax Authority, and (ii) give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, Spectra MLP, MLP GP or SE Transmission, as the case may be, shall allow the other parties to take possession of such books and records. Spectra MLP, MLP GP and SE Transmission each agree, upon request, to use Reasonable Efforts to obtain any certificate or other document from any Tax 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.

     Section 7.2 Transfer Taxes. Responsibility for the payment of all state and local transfer, sales, use, stamp, registration or other similar Taxes resulting from the transactions contemplated by this Agreement shall be borne 50% by Spectra MLP and 50% by SE Transmission and MLP GP in proportion to their ownership of the Saltville Companies prior to this Agreement.

Spectra MLP shall be solely liable for, shall pay and shall protect, defend, indemnify and hold harmless each of SE Transmission and

MLP GP from any and all Taxes which relate to or result from the income, Business, property or operations of the Saltville Companies after the Effective Time.

          (b) If any claim (an “Indemnified Tax Claim”) is made by any Tax 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 7.3, the Tax Indemnified Party shall promptly, but in no event later than the earlier of (i) 45 days after receipt of notice from the Tax 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.

          (c) 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 Section 7.3(b) 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 Section 7.3(b) 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.

     Section 7.4 Scope. Notwithstanding anything to the contrary herein, this Article VII shall be the exclusive remedy for any claims relating to Taxes (including any claims relating to representations respecting Tax matters including Section 4.10). The rights under this Article VII shall survive the Closing until 30 days after the expiration of the statute of limitations (including extensions) applicable to such Tax matter. 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.

     Section 7.5 Tax Refunds. In the event that Spectra MLP receives any refund of Taxes from a taxing jurisdiction or a reimbursement of Taxes from a third party with respect to any Pre-Closing Taxable Period (which refund is not reflected in “Accrued Taxes” on the balance sheet of Saltville LLC dated as of the Closing Date prepared in connection with the determination of Final Net Working Capital), such amounts shall belong to SE Transmission and MLP GP and shall be forwarded by Spectra MLP to SE Transmission and MLP GP in proportion to such Party’s ownership of Saltville LLC prior to this Agreement within 10 days of receipt.

ARTICLE IX
INDEMNIFICATION

     Section 9.1 Survival.

          (a) The representations and warranties of the Parties contained in this Agreement and all covenants contained in this Agreement that are to be performed prior to the Closing will survive the closing for 18 months following the Closing; provided, however, that

(i) the Fundamental Representations and Warranties shall survive for the applicable statute of limitations, (ii) the representations and warranties set forth in Section 4.10 shall survive as set forth in Article VII and (iii) the representations and warranties in Section 4.11 shall survive for three years following the Closing. The P-25 Indemnity Obligations (as defined below) shall survive as set forth in the Asset Purchase Agreement. No Party shall have any liability for indemnification claims made under this Article IX with respect to any such representation, warranty or pre-closing covenant unless a Claim Notice is provided by the non-breaching Party to the other Party prior to the expiration of the applicable survival period for such representation, warranty or pre-closing covenant. If a Claim Notice has been timely given in accordance with this Agreement prior to the expiration of the applicable survival period for such representation, warranty or pre-closing covenant or claim, then the applicable representation, warranty or pre-closing covenant shall survive as to such claim, until such claim has been finally resolved.

          (b) All covenants and agreements of the Parties contained in this Agreement to be performed after the Closing will survive the Closing in accordance with their terms.

     Section 9.2 Indemnification.

          (a) Subject to Article VII relating to Taxes, the provisions of this Article IX and, as to the P-25 Indemnity Obligations, all rights, counterclaims, defenses and limitations available under the Asset Purchase Agreement to SE Virginia Pipeline (except for defenses arising from the involuntary bankruptcy, insolvency, dissolution or liquidation of SE Virginia Pipeline), from and after the Closing, each of SE Transmission and MLP GP shall indemnify and hold harmless Spectra MLP, Spectra MLP’s Affiliates (other than SE Transmission and MLP GP) and their respective Representatives (the “Spectra MLP Indemnified Parties”) from and against all Losses that Spectra MLP Indemnified Parties incur arising from (i) any breach of any representation, warranty or covenant of SE Transmission or MLP GP, as applicable, in this Agreement or in the certificates to be delivered at Closing or (ii) any breach of any representation, warranty or covenant of SE Virginia Pipeline at or prior to closing under the Asset Purchase Agreement or in the certificates delivered at the closing thereunder or any indemnity obligation thereunder relating to periods on or prior to the closing thereunder (collectively, the “P-25 Indemnity Obligations”).

          (b) Subject to Article VII relating to Taxes and the provisions of this Article IX, from and after the Closing, Spectra MLP shall indemnify and hold harmless SE Transmission and its Affiliates and their respective Representatives (the “SE Transmission Indemnified Parties”) and MLP GP and its Affiliates and their respective Representatives (the “MLP GP Indemnified Parties”) from and against all Losses that each of the SE Transmission Indemnified Parties and MLP GP Indemnified Parties incur arising from or out of (i) any breach of any representation, warranty or covenant of Spectra MLP in this Agreement or in the certificate to be delivered at Closing or (ii) relating to any Company Guarantees.

          (c) Notwithstanding anything to the contrary herein, the Parties shall have a duty to use Reasonable Efforts to mitigate any Loss arising out of or relating to this Agreement or the transactions contemplated hereby.

          (d) Notwithstanding anything to the contrary herein, to the extent that any Spectra MLP Indemnified Party incurs Losses arising from any breach of any representation, warranty or covenant of SE Transmission or MLP GP, as applicable, in this Agreement, and recourse is available to it for all or a portion of such Losses under the AGL Agreement, then such Spectra MLP Indemnified Party shall give SE Transmission and MLP GP a Claim Notice therefor and first use its Reasonable Efforts for a period of one year to seek indemnification under the AGL Agreement and shall have recourse hereunder for such Losses only to the extent not recovered pursuant to the AGL Agreement. The delivery of a Claim Notice in respect of such Losses shall toll the applicable survival period under Section 9.1 for the duration of such year. Notwithstanding the foregoing, Spectra MLP agrees not to initiate litigation pursuant to the AGL Agreement and, at such time as it determines efforts at recovery pursuant to the AGL Agreement short of litigation are unlikely to be successful, Spectra MLP shall notify SE Transmission thereof and SE Transmission may then freely pursue such litigation. If SE Transmission decides to initiate such litigation prior to the end of the above-referenced one year period, or otherwise as of the expiration of such one year period, Spectra MLP shall no longer be obligated to seek recourse under the AGL Agreement with respect to the applicable matters.

          (e) Notwithstanding anything in this Article IX to the contrary, all Losses relating to Taxes which are the subject of Article VII shall only be subject to indemnification under Section 7.3.

     Section 9.3 Indemnification Procedures. Claims for indemnification under this Agreement (other than claims involving a Tax Proceeding, the procedures for which are set forth in Article VII) shall be asserted and resolved as follows:

          (a) Any Spectra MLP Indemnified Party, MLP GP Indemnified Party or SE Transmission Indemnified Party claiming indemnification under this Agreement (an “Indemnified Party”) with respect to any claim asserted against the Indemnified Party by a third party (“Third Party Claim”) in respect of any matter that is subject to indemnification under Section 9.2 shall promptly (i) notify the appropriate Party (the “Indemnifying Party”) of the Third Party Claim and (ii) transmit to the Indemnifying Party a written notice (“Claim Notice”) describing in reasonable detail the nature of the Third Party Claim, a copy of all papers served with respect to such claim (if any), the Indemnified Party’s best estimate of the amount of Losses attributable to the Third Party Claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. Failure to timely provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is prejudiced by such delay or omission.

          (b) The Indemnifying Party shall have the right to defend the Indemnified Party against such Third Party Claim. If the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party elects to assume the defense of the Third Party Claim, then the Indemnifying Party shall have the right to defend such Third Party Claim with counsel selected by the Indemnifying Party (who shall be reasonably satisfactory to the Indemnified Party), by all appropriate proceedings, to a final conclusion or settlement at the discretion of the Indemnifying Party in accordance with this Section 9.3(b). The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided, however, that the Indemnifying Party shall not enter into any settlement agreement without the

written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed); provided, further, that such consent shall not be required if (i) the settlement agreement contains a complete and unconditional general release by the third party asserting the claim to all Indemnified Parties affected by the claim and (ii) the settlement agreement does not contain any sanction or restriction upon the conduct of any business by the Indemnified Party or its Affiliates. If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest, including the making of any related counterclaim against the Person asserting the Third Party Claim or any cross complaint against any Person. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 9.3(b), and the Indemnified Party shall bear its own costs and expenses with respect to such participation.

          (c) If the Indemnifying Party does not notify the Indemnified Party that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 9.3(b), then the Indemnified Party shall have the right to defend, and be reimbursed for its reasonable cost and expense (but only if the Indemnified Party is actually entitled to indemnification hereunder) in regard to the Third Party Claim with counsel selected by the Indemnified Party (who shall be reasonably satisfactory to the Indemnifying Party), by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnified Party. In such circumstances, the Indemnified Party shall defend any such Third Party Claim in good faith and have full control of such defense and proceedings; provided, however, that the Indemnified Party may not enter into any compromise or settlement of such Third Party Claim if indemnification is to be sought hereunder, without the Indemnifying Party’s consent (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 9.3(c), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

          (d) Subject to the other provisions of this Article IX, a claim for indemnification for any matter not involving a Third Party Claim may be asserted by notice to the Party from whom indemnification is sought.

          (e) Notwithstanding anything to the contrary in this Section 9.3, the indemnification procedures set forth in Article VII shall control any indemnities relating to Taxes.

     Section 9.4 Additional Agreements Regarding Indemnification. Notwithstanding anything to the contrary herein:

          (a) a breach of any representation or warranty (other than with respect to a breach of the Fundamental Representations and Warranties) of SE Transmission or MLP GP in this Agreement in connection with any single item or group of related items that results in Losses of less than $10,000 shall be deemed, for all purposes of this Article IX not to be a breach of such representation, warranty or pre-closing covenant;

          (b) neither SE Transmission nor MLP GP shall have any liability arising out of or relating to Section 9.2(a) for breaches of representations or warranties (other than with respect to a breach of the Fundamental Representations and Warranties) or the P-25 Indemnity Obligations except if the aggregate Losses actually incurred by Spectra MLP Indemnified Parties thereunder exceed $1,070,000 (and then, subject to Section 9.4(c), only to the extent such aggregate Losses exceed such amount);

          (c) in no event shall the aggregate liability of SE Transmission or MLP GP arising out of or relating to Section 9.2(a) for breaches of representations or warranties (other than with respect to a breach of the Fundamental Representations and Warranties) or the P-25 Indemnity Obligations exceed $21,400,000;

          (d) the amount of any Loss for which a Spectra MLP Indemnified Party claims indemnification under this Agreement shall be reduced by: (i) any insurance proceeds actually recovered with respect to such Loss; (ii) any Tax Benefits with respect to such Loss and (iii) indemnification or reimbursement payments actually recovered from third parties with respect to such Loss;

          (e) for purposes of determining whether there has been a breach or inaccuracy of a representation or warranty by a party in connection with the assertion of a claim for indemnification under Article IX, or determining the amount of a Loss, with respect to any asserted breach or inaccuracy, such determination shall be made without regard to any qualifier as to “material,” “materiality” or Material Adverse Effect expressly contained in Article III or IV;

          (f) as contemplated by Section 6.10(b), none of SE Transmission and MLP GP and their respective Affiliates shall have any liability hereunder that arises out of or relating to the Excluded Assets;

          (g) the provisions of Section 8.4(b) and Section 8.4(c) of the Asset Purchase Agreement do not apply as to any claim for a P-25 Indemnity Obligation brought hereunder; and

          (h) for the avoidance of doubt, nothing in this Section 9.4 shall affect the provisions of Article VII.

     Section 9.5 Waiver of Other Representations.

          (a) NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, IT IS THE EXPLICIT INTENT OF EACH PARTY HERETO, AND THE PARTIES HEREBY AGREE, THAT NONE OF SE TRANSMISSION, MLP GP OR ANY OF THEIR RESPECTIVE AFFILIATES OR REPRESENTATIVES HAS MADE OR IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, WRITTEN OR ORAL, INCLUDING ANY IMPLIED REPRESENTATION OR WARRANTY AS TO THE CONDITION, MERCHANTABILITY, USAGE, SUITABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE WITH RESPECT TO THE CONTRIBUTED INTERESTS, THE SALTVILLE COMPANIES, THEIR ASSETS OR ANY PART THEREOF, EXCEPT THOSE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, AND WITHOUT IN ANY WAY LIMITING THE FOREGOING, NEITHER

SE TRANSMISSION NOR MLP GP MAKES ANY REPRESENTATION OR WARRANTY TO SPECTRA MLP WITH RESPECT TO ANY FINANCIAL PROJECTIONS OR FORECASTS RELATING TO THE SALTVILLE COMPANIES.

          (b) The representations and warranties contained in Section 4.11 shall be the exclusive representations and warranties with regard to Environmental Laws and related matters.

     Section 9.6 Total Consideration Adjustment. The Parties agree to treat all payments made pursuant to this Article IX as adjustments to the SET Consideration and MLP GP Consideration, as applicable, for Tax purposes.

     Section 9.7 Exclusive Remedy.

          (a) Notwithstanding anything to the contrary herein except as provided in Sections 7.2, 7.3, 9.2 or 10.2, no Party shall have any liability, and no Party shall make any claim, for any Loss or other matter (and Spectra MLP, MLP GP and SE Transmission hereby waive any right of contribution against the other and their respective Affiliates), under, arising out of or relating to this Agreement, any other document, agreement, certificate or other matter delivered pursuant hereto or the transactions contemplated hereby, whether based on contract, tort, strict liability, other Laws or otherwise.

          (b) NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, NO PARTY SHALL BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES, LOST PROFITS, LOST OPPORTUNITIES OR OTHER SPECULATIVE DAMAGES, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM ANY OTHER PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT; PROVIDED, HOWEVER, THAT THIS SECTION 9.7(b) SHALL NOT LIMIT A PARTY’S RIGHT TO RECOVERY UNDER ARTICLE IX FOR ANY SUCH DAMAGES TO THE EXTENT SUCH PARTY IS REQUIRED TO PAY SUCH DAMAGES TO A THIRD PARTY IN CONNECTION WITH A MATTER FOR WHICH SUCH PARTY IS OTHERWISE ENTITLED TO INDEMNIFICATION UNDER ARTICLE IX.
