pursuant to the notice provisions hereof. If (a) SE Transmission or MLP GP so furnishes
supplemental information, (b) the absence of such information would have resulted in a breach of
any representation or warranty under this Agreement and (c) the Closing occurs, then such
information shall be deemed to amend this Agreement and the Disclosure Schedule for all purposes
hereunder; provided, however, that if such supplemental disclosure would or would reasonably be
expected to result in Losses to the Saltville Companies in excess of $2,500,000 in the aggregate,
then Spectra MLP may elect, by written notice delivered to SE Transmission and MLP GP to terminate
this Agreement no later than two Business Days before Closing.

     Section 6.8 Books and Records. From and after the Closing, Spectra MLP shall preserve and
keep a copy of all books and records (other than Tax records which are addressed in Article VII)
relating to the Business or operations of the Saltville Companies on or before the Closing Date in
Spectra MLP’s possession for a period of at least seven years after the Closing Date. After such
seven year period, before Spectra MLP shall dispose of any such books and records, Spectra MLP
shall give each of SE Transmission and MLP GP at least 90 days prior notice to such effect, and
each of SE Transmission and MLP GP shall be given an opportunity, at their cost and expense, to
remove and retain all or any part of such books and records as each of SE Transmission and MLP GP
may select. Spectra MLP shall provide to each of SE Transmission and MLP GP, at no cost or expense
to such Party, reasonable access during business hours to such books and records as remain in
Spectra MLP’s possession and reasonable access during business hours to the properties and
employees of Spectra MLP and any of the Saltville Companies in connection with matters relating to
the Business or operations of the Saltville Companies on or before the Closing Date and any
disputes relating to this Agreement.

     Section 6.9 Permits. SE Transmission, MLP GP and Spectra MLP shall cooperate to provide all
notices and otherwise take all reasonable actions required to transfer or reissue any Permits,
including those required under Environmental Laws, as a result of or in furtherance of the
transactions contemplated by this Agreement.

     Section 6.10 Excluded Assets.

          (a) Spectra MLP acknowledges that the Saltville Companies will, prior to the Closing, convey,
assign and transfer to SE Transmission or one of its Affiliates (other than the Saltville
Companies), all right, title and interest in and to the consideration received pursuant to the
Asset Purchase Agreement and the other assets, properties and rights (and associated liabilities
and obligations) and the liabilities and obligations (and associated assets, properties and rights)
described or referenced in Schedule 6.10 and neither Spectra MLP nor the Saltville
Companies shall have any claims or rights with respect to such consideration, assets, properties,
rights, liabilities and obligations (such assets, properties, rights, liabilities and obligations,
the “Excluded Assets”) under this Agreement.

27

 

          (b) Notwithstanding anything herein to the contrary, (i) all references herein to any
revenues, expenses, assets, or liabilities of the Saltville Companies shall expressly exclude the
Excluded Assets, (ii) all references herein to the Business, whether with respect to financial,
accounting, legal, Tax or other position or operation, shall expressly exclude the businesses or
the position or operation of the businesses included in the Excluded Assets and (iii) none of SE
Transmission and MLP GP and their respective Affiliates makes any representations, warranties or
covenants with respect to the Excluded Assets.

     Section 6.11 Noncompetition Agreement. From and after the Closing Date, Spectra MLP shall
cause Saltville LLC to comply with the terms of the Noncompetition Agreement, dated as of
October 11, 2001, by and between Virginia Gas Company and Heritage Holdings, Inc.

     Section 6.12 Asset Purchase Agreement. Spectra MLP shall (i) cause East Tennessee Natural
Gas, LLC and, from and after the Closing, Saltville LLC (as successor-in-interest by merger to SE
Virginia Pipeline under the Asset Purchase Agreement) to refrain from amending, supplementing, or
otherwise modifying the Asset Purchase Agreement without the prior written consent of SE
Transmission (which consent SE Transmission may withhold in its sole discretion) and (ii) promptly
forward to SE Transmission any notices given by East Tennessee Natural Gas, LLC to Saltville LLC in
connection with the Asset Purchase Agreement.

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 301.7701-3(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

28

 

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

29

 

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.

     Section 7.3 Tax Indemnity.

          (a) SE Transmission and MLP GP shall be jointly and severally liable for, shall pay and shall
protect, defend, indemnify and hold harmless Spectra MLP and the Saltville Companies from (i) any
breach of the representations and warranties contained in Section 4.10, (ii) any and all Taxes in
excess of any liability for Taxes (for the period through the Effective Time) reflected in the
Final Net Working Capital which relate to or result from the income, Business, property or
operations of the Saltville Companies prior to the Effective Time, (iii) any Taxes arising as a
result of the Saltville Restructuring and (iv) with respect to any tax liabilities of the Saltville
Companies as a result of the provisions of Treasury Regulation Section 1.1502-6 or any similar
provision of foreign, state or local law. Spectra MLP shall be solely liable for, shall pay and
shall protect, defend, indemnify and hold harmless each of SE Transmission and

30

 

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.

     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

33

 

(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.

34

 

          (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

35

 

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;

36

 

          (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

hereby.

     Section 11.7 Disclosure Schedule. Unless the context otherwise requires, all capitalized
terms used in the Disclosure Schedule shall have the respective meanings assigned in this
Agreement. No reference to or disclosure of any item or other matter in the Disclosure Schedule
shall be construed as an admission or indication that such item or other matter is material or that

this Agreement, then they shall take any actions necessary to render the remaining provisions of
this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent
necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein
that is held invalid or unenforceable with a valid and enforceable provision giving effect to the

determination or finding is mandated due to the Law being that of a different jurisdiction, the
Parties agree that all judicial determinations or findings by a state or federal court in Houston,
Texas with respect to any matter under this Agreement shall be binding.

jurisdiction of any court or from any legal process (whether through service or notice, attachment
prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself
or its property, each such party hereby irrevocably (i) waives such immunity in respect of its
obligations with respect to this Agreement and (ii) submits to the personal jurisdiction of any
court described in Section 11.11(b).

          (d) THE PARTIES HERETO AGREE THAT THEY HEREBY IRREVOCABLY WAIVE THE RIGHT TO TRIAL BY JURY IN

     Section 11.12 Action by Spectra MLP. With respect to any action (including any case where the

by another Party (the “Tax Indemnifying Party”) under this Section 6.3, the Tax Indemnified
Party shall promptly, but in no event later than the earlier of (i) 45 days after receipt of notice

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

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 6.4 Scope. Notwithstanding anything to the contrary herein, this Article VI shall be the exclusive
remedy for any claims relating to Taxes (including any claims relating to

representations
respecting Tax matters including Section 3.8). The rights under this Article VI 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

ARTICLE VIII

INDEMNIFICATION

     Section 8.1 Survival

22

 

          (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 3.8 shall survive as set forth in Article VI
and (iii) the representations and warranties in Section 3.10 shall survive for three years
following the Closing. No Party shall have any liability for indemnification claims made under
this Article VII 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 8.2 Indemnification.

          (a) Subject to Article VI relating to Taxes and the provisions of this Article VIII, from and
after the Closing, Seller shall indemnify and hold harmless Buyer, Buyer’s Affiliates and their
respective Representatives (the “Buyer Indemnified Parties”) from and against all Losses that Buyer
Indemnified Parties incur arising from any breach of any representation, warranty or covenant of
Seller in this Agreement or in the certificate to be delivered at Closing.

          (b) Subject to Article VI relating to Taxes and the provisions of this Article VIII, from and
after the Closing, Buyer shall indemnify and hold harmless Seller, Seller’s Affiliates and their
respective Representatives (the “Seller Indemnified Parties”) from and against all Losses that the
Seller Indemnified Parties incur arising from or out of (i) any breach of any representation,
warranty or covenant of Buyer in this Agreement or in the certificate to be delivered at Closing,
(ii) the Assumed Liabilities or (iii) the 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 in this Article VIII to the contrary, all Losses relating to
Taxes which are the subject of Article VI shall only be subject to indemnification under Section
6.3.

     Section 8.3 Indemnification Procedures. Claims for indemnification under this Agreement (other than claims involving a Tax
Proceeding, the procedures for which are set forth in Article VI) shall be asserted and resolved as
follows:

          (a) Any Buyer Indemnified Party or Seller Indemnified Party claiming indemnification under
this Agreement (an “Indemnified Party”) with respect to any claim

23

 

asserted against the Indemnified
Party by a third party (“Third Party Claim”) in respect of any matter that is subject to
indemnification under Section 8.2 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 8.3(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
8.3(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 8.3(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,

24

 

any defense or settlement controlled by the
Indemnified Party pursuant to this Section 8.3(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 VIII, 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 8.3, the indemnification
procedures set forth in Article VI shall control any indemnities relating to Taxes.

     Section 8.4 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 Seller 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 VIII not to be a breach of such representation, warranty or
pre-closing covenant;

          (b) Seller shall have no liability arising out of or relating to Section 8.2(a) for breaches
of representations or warranties (other than with respect to a breach of the Fundamental
Representations and Warranties) except if the aggregate Losses actually incurred by Buyer
Indemnified Parties thereunder exceed $253,000 (and then, subject to Section 8.4(c), only to the
extent such aggregate Losses exceed such amount);

          (c) in no event shall the aggregate liability of Seller arising out of or relating to Section
8.2(a) for breaches of representations or warranties (other than with respect to a breach of the
Fundamental Representations and Warranties) exceed $5,060,000;

          (d) the amount of any Loss for which a Buyer 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 VIII, 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;

          (f) as contemplated by Section 5.9, neither Seller nor any of its Affiliates shall have any
liability hereunder that arises out of or relating to the Excluded Assets; and

          (g) for the avoidance of doubt, nothing in this Section 8.4 shall affect the provisions of
Article VI.

25

 

     Section 8.5 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 SELLER OR ANY OF ITS 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 PURCHASED ASSETS OR ANY PART
THEREOF, EXCEPT THOSE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, AND WITHOUT IN
ANY WAY LIMITING THE FOREGOING, SELLER MAKES NO REPRESENTATION OR WARRANTY TO BUYER WITH RESPECT TO
ANY FINANCIAL PROJECTIONS OR FORECASTS RELATING TO THE PURCHASED ASSETS.

          (b) The representations and warranties contained in Section 3.10 shall be the exclusive
representations and warranties with regard to Environmental Laws and related matters.

     Section 8.6 P-25 Total Unit Consideration Adjustment. The Parties agree to treat all payments made pursuant to this Article VIII as adjustments
to the P-25 Total Unit Consideration for Tax purposes.

     Section 8.7 Exclusive Remedy.

          (a) Notwithstanding anything to the contrary herein except as provided in Sections 6.2, 6.3,
8.2 or 9.2, no Party shall have any liability, and no Party shall make any claim, for any Loss or
other matter (and each Party hereby waives any right of contribution against the other Party and
its 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 8.7(b) SHALL NOT
LIMIT A PARTY’S RIGHT TO RECOVERY UNDER ARTICLE VIII 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 VIII.

26
