Any indemnification provided pursuant to this Agreement shall not be duplicative of any indemnification provided pursuant to the Omnibus Agreement. Further, if entitled to indemnification under this Section 8.1 , the SHLX Indemnified Parties may seek indemnification from either SPLC or SOPUS, as applicable, but may recover an aggregate amount not to exceed the above specified percentage of the Damages and subject to all other limitations set forth in this Agreement, including Article VIII hereof.

33

Section 8.3 Survival .

All the provisions of this Agreement shall survive the Closing, notwithstanding any investigation at any time made by or on behalf of any party hereto, provided that the representations and warranties set forth in Article III and Article IV shall terminate and expire on the date that is eighteen (18) months following the Closing Date, except (a) the representations and warranties of SPLC and SOPUS set forth in Section 3.9 (Taxes) shall survive until the date that is sixty (60) days after the expiration of the applicable statutes of limitations (including all periods of extension and tolling), (b) the representations and warranties of SPLC and SOPUS set forth in Section 3.10 (Environmental Matters) shall terminate and expire on the third (3rd) anniversary of the Closing Date, (c) the representations and warranties of SPLC and SOPUS set forth in Section 3.1 (Organization), Section 3.2 (Authority and Approval), Section 3.4(a) (Capitalization; Title to Subject Interests) and Section 3.17 (Brokerage Arrangements) shall survive until the expiration of the applicable statute of limitations, and (d) the representations and warranties of SHLX set forth in Section 4.1 (Organization and Existence), Section 4.2 (Authority and Approval) and Section 4.5 (Brokerage Arrangements) shall survive until the expiration of the applicable statute of limitations.

The indemnification obligations under this Article VIII or elsewhere in this Agreement shall apply regardless of whether any suit or action results solely or in part from the active, passive or concurrent negligence or strict liability of the indemnified party. The covenants and agreements entered into pursuant to this Agreement to be performed after the Closing shall survive the Closing.

Section 8.4 Indemnification Procedures .

(a) The indemnified party hereunder agrees that within a reasonable period of time after it becomes aware of facts giving rise to a claim for indemnification under this Article VIII , it will provide notice thereof in writing to the indemnifying party, specifying the nature of and specific basis for such claim.

(b) The indemnifying party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the indemnified party that are covered by the indemnification under this Article VIII , including the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such claim or any matter or any issues relating thereto; provided, however, that no such settlement for only the payment of money shall be entered into without the consent of the indemnified party, which consent shall not be unreasonably withheld, conditioned or delayed, unless it includes a full

34

release of the indemnified party from such claim; provided further, that no such settlement containing any form of injunctive or similar relief shall be entered into without the prior written consent of the indemnified party, which consent shall not be unreasonably delayed or withheld.

(c) The indemnified party agrees to cooperate in good faith and in a commercially reasonably manner with the indemnifying party, with respect to all aspects of the defense of and pursuit of any counterclaims with respect to any claims covered by the indemnification under this Article VIII , including the prompt furnishing to the indemnifying party of any correspondence or other notice relating thereto that the indemnified party may receive, permitting the name of the indemnified party to be utilized in connection with such defense and counterclaims, the making available to the indemnifying party of any files, records or other information of the indemnified party that the indemnifying party considers relevant to such defense and counterclaims, the making available to the indemnifying party of any employees of the indemnified person and the granting to the indemnifying party of reasonable access rights to the properties and facilities of the indemnified party; provided, however, that in connection therewith the indemnifying party agrees to use reasonable efforts to minimize the impact thereof on the operations of the indemnified party and further agrees to maintain the confidentiality of all files, records, and other information furnished by the indemnified party pursuant to this Section. The obligation of the indemnified party to cooperate with the indemnifying party as set forth in the immediately preceding sentence shall not be construed as imposing upon the indemnified party an obligation to hire and pay for counsel in connection with the defense of and pursuit of any counterclaims with respect to any claims covered by the indemnification set forth in this Article VIII , provided, however, that the indemnified party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense and counterclaims. The indemnifying party agrees to keep any such counsel hired by the indemnified party informed as to the status of any such defense or counterclaim, but the indemnifying party shall have the right to retain sole control over such defense and counterclaims so long as the indemnified party is still seeking indemnification hereunder.

(d) In determining the amount of any Damages for which the indemnified party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the indemnified person in respect of such Damages from third party insurers, and such correlative insurance benefit shall be net of any expenses related to the receipt of such proceeds, including any premium adjustments that become due and payable by the indemnified party as a result of such claim, and (ii) all amounts recovered by the indemnified party in respect of such Damages under contractual indemnities from third persons.

Section 8.5 Direct Claim .

Any claim by an indemnified party with respect to any Damages which do not result from a claim for indemnity involving a third party (a “ Direct Claim ”) will be asserted by giving the indemnifying party reasonably prompt written notice thereof, stating the nature of such claim in reasonable detail and indicating the estimated amount, if practicable. The indemnifying party will have a period of ninety (90) days from receipt of such Direct Claim within which to respond to such Direct Claim. If the indemnifying party does not respond within such ninety (90) day period, the indemnifying party will be deemed to have accepted such Direct Claim. If the indemnifying party rejects such Direct Claim, the indemnified party will be free to seek enforcement of its rights to indemnification under this Agreement.

35

Section 8.6 Limitations on Indemnification .

(a) To the extent that SHLX Indemnified Parties would otherwise be entitled to indemnification for Damages pursuant to Section 8.1(a) , SPLC and SOPUS, jointly and severally, shall be liable only if (i) the Damages with respect to any individual claim exceed One Hundred Thousand Dollars ($100,000) (the “ Minimum Claim Amount ”) and (ii) the Damages for all claims that exceed the Minimum Claim Amount exceed, in the aggregate, One Million Dollars ($1,000,000) (the “ Deductible Amount ”), and then SPLC and SOPUS, jointly and severally, shall be liable only for Damages to the extent of any excess over the Deductible Amount. In no event shall SPLC’s and SOPUS’s aggregate liability to SHLX Indemnified Parties under Section 8.1 exceed Thirty-Five Million Dollars ($35,000,000) (the “ Ceiling Amount ”). Notwithstanding the foregoing, (i) SPLC’s and SOPUS’s aggregate liability to SHLX Indemnified Parties under Section 8.1 for breaches or inaccuracies of representations and warranties contained in Section 3.20 (Management Projections and Budget) shall not be subject to the Ceiling Amount but shall not exceed One Hundred Seventy Five Million Dollars ($175,000,000) and (ii) the Deductible Amount and the Ceiling Amount shall not apply to breaches or inaccuracies of representations and warranties contained in Section 3.1 (Organization), Section 3.2 (Authority and Approval), Section 3.4 (Capitalization; Title to Subject Interests), Section 3.9 (Taxes), Section 3.17 (Brokerage Arrangements) and Section 3.18 (Books and Records), provided, that SPLC’s and SOPUS’s aggregate liability for all claims under this Agreement, including for breaches or inaccuracies of representations and warranties contained in such sections described in clauses (i) and (ii) and for breaches of covenants, shall not exceed the Consideration.

(b) For purposes of determining the amount of Damages, with respect to any asserted claim for indemnification by a SHLX Indemnified Party, such determination shall be made without regard to any qualifier as to “material,” “materiality” or SPLC Material Adverse Effect expressly contained in Article III (except in the case of the term “ Material Contract ”); provided that this Section 8.6(b) shall not so modify the representations and warranties for purposes of first determining whether a breach of any representation or warranty has occurred.

(c) Additionally, neither SPLC nor SOPUS, on the one hand, nor SHLX and Operating, on the other hand, will be liable as an indemnitor under this Agreement for any consequential, incidental, special, indirect or exemplary damages suffered or incurred by the indemnified party or parties except to the extent resulting pursuant to third party indemnity claims.
