ARTICLE V     
ADDITIONAL AGREEMENTS, COVENANTS, RIGHTS AND OBLIGATIONS

(a)     Except as expressly provided by this Agreement, or as consented to in writing by the other parties to this Agreement, during the period from the date of this Agreement through the Closing Date, as to their respective interests in the Assets, each of the Sellers shall, or shall cause its representative(s) to:

(b)     Except (i) as expressly provided by this Agreement, (ii) as set forth on Section 5.1 of the Disclosure Letter or (iii) as consented to in writing by the other parties to this Agreement, during the period from the date of this Agreement through the Closing Date, as to their respective interests in the Assets, none of the Sellers shall, and shall cause their representative(s) not to:

After Closing, Shell Chemical covenants and agrees that, if Shell Chemical becomes aware that the catalytic converter unit(s) will be permanently taken out of service or otherwise permanently shut down, then Shell Chemical will promptly provide written notice to Sand Dollar of Shell Chemical’s election to convert or not all or part of the Convent RG Pipeline and/or the NBR Line from refinery gas service to either butane or propylene service or both, pursuant to the terms of the Transportation Service Agreement related to the Convent RG Pipeline. Shell Chemical covenants and agrees that it will pay the capital costs and project costs incurred for such conversion(s). Such conversion(s) will result in additional connections being made to the Convent RG Pipeline and/or to the NBR Line (“ RGP Connections ”). Shell Chemical agrees, upon completion of the RGP Connections and at or immediately prior to the commencement of commercial operations on such converted pipelines, to convey such RGP Connections to Sand Dollar for nominal consideration (not exceeding $10.00) by a bill of sale, in a form to be mutually agreed between Shell Chemical and Sand Dollar. Shell Chemical and Sand Dollar also agree to execute connection agreements, as applicable, for each additional connection, in substantially the same form as a Connection Agreement executed by Shell Chemical and Sand Dollar at Closing. For purposes of this Section 5.2 , “permanently shut down” or “permanently out of service” means a shut down that will last at least two (2) years.

(a)     Notwithstanding anything to the contrary contained in this Agreement, if the parties consummate the Closing prior to the applicable Seller thereof obtaining a required third party consent or approval in connection with the assignment or transfer of any right-of-way, easement, servitude, permit, license, contract, or similar interest related to the transfer of any of the Assets, including any right-of-way, easements, or servitude held in the name of an Affiliate of a Seller (a “ Non-Assigned Asset ”), then such Non-Assigned Asset shall not be assigned by such Seller or its Affiliate to the applicable Purchaser at the Closing and shall be retained by the applicable Seller or its Affiliate until such time as the consent or approval is received or alternative resolution mutually satisfactory to such Seller and the Purchasers is reached, such Non-Assigned Asset shall be deemed to be held by such Seller or its Affiliate for the benefit of the applicable Purchaser until such time as the consent or approval is received or such a mutually satisfactory alternative resolution is reached, and the Consideration shall not be reduced. Until such time as the consent or approval to the assignment or transfer of any Non-Assigned Asset is received or mutually satisfactory alternative resolution is reached, (i) such Seller shall provide, or shall cause each of its Affiliates to provide, the applicable Purchaser with the economic benefits of the Non-Assigned Asset held in its name, or name of its Affiliate if applicable, and (ii) such Seller and the applicable Purchaser shall use their respective reasonable efforts, at such Seller’s cost and expense, to obtain the third party consent(s) or approvals or reach a mutually satisfactory alternative resolution. The Sellers agree to pay any costs or fees that are required to be paid to any Governmental Authority or to any landowner or other party that is not an Affiliate of a Seller to obtain such consent and/or approval. For purposes of this Agreement, if the Non-Assigned Asset is a right-of-way, easement, servitude, or similar right, then the associated pipeline or other Asset located thereon will be transferred at Closing by the applicable bill of sale and assignment, but the applicable right-of-way, easement, servitude, or similar right constituting the Non-Assigned Asset(s) will be held by such Seller or Seller’s Affiliate until such consent or approval is received or until a mutually satisfactory alternative resolution is reached. Upon receipt of the third party consent or approval or achieving a mutual agreement to an alternative resolution related to a Non-Assigned Asset, the assignment of such Non-Assigned Asset shall automatically become effective without the need for any further action on the part of the parties or any other person and without the payment of any additional consideration. However, if a Seller or Purchaser requires that an assignment of a Non-Assigned Asset be recorded in the real property records in order to put third parties on notice of such assignment or otherwise reasonably requires that such assignment be documented, then at the Seller’s cost the applicable parties will execute an additional assignment of rights-of-way as to such Non-Assigned Asset after the required consent or approval is received or an alternative resolution is reached, and at the Purchasers’ expense the additional assignment of rights-of-way will be recorded in the real property records of the county or parish in which the underlying real property is located. Notwithstanding the foregoing, if a consent or approval is not received or mutually acceptable alternative solution is not reached within two (2) years after the Closing Date, then such Non-Assigned Asset shall be deemed assigned and SHLX and the applicable Purchaser shall assume all obligations and liabilities related to such Non-Assigned Asset as of such date.

(b)     If an Affiliate of GOM and SPLC holds a right-of-way, easement, servitude, or similar right related to the Na Kika Assets in its name for the benefit of GOM and/or SPLC as the operator prior to the Effective Time, and such Affiliate will continue to hold such right in its name after Closing, then from and after the Effective Time, GOM and SPLC will cause its Affiliate to continue to hold such right in its own name but for the benefit of Pecten pursuant to and in accordance with the terms of the amendment to the Pecten Operating Agreement.

(c)     As soon as practicable, Sellers will complete any necessary survey work for and grant (or cause a Seller’s Affiliate to grant) fully paid, permanent easements, in a form to be mutually agreed upon between the applicable Seller and Purchaser, to the applicable Purchaser, such easements to be reasonably sufficient for the operation or ownership of any of the Assets that are located on fee or leasehold interests of a Seller or a Seller’s Affiliate, which real property interests will not be conveyed as part of the Transaction. Such real property interests over which an easement would be granted are more fully described in Section 5.3(c) of the Disclosure Letter . The Sellers shall pay for all reasonable costs related to such survey work. If any such easements require the prior consent or approval of a third party or Governmental Authority, then the applicable Seller and the applicable Purchaser shall use their respective reasonable efforts, at such Seller’s cost and expense, to obtain such consent or approval or reach an alternative resolution that is mutually satisfactory to such Seller and such Purchaser. Unless otherwise agreed by the parties hereto and subject to this Section 5.3 , SHLX or its designee shall record any easements granted pursuant to this Section 5.3(c) in the real property records of the county or parish in which the underlying real property interest is located, at SHLX’s expense. If such survey work is not completed such that an easement(s) cannot be granted at the Closing Date, the parties agree to use their respective reasonable efforts to complete such survey work and execute such easement post-Closing.

At Closing, SPLC and Shell Chemical will cause to be executed a termination of the NBR Line Lease, with such termination to be effective at the Effective Time, and all costs incurred in connection therewith shall be borne by SPLC and Shell Chemical.

If the Closing occurs, then Pecten and SPLC shall enter into and file a joint tariff agreement (in a form to be mutually agreed upon between Pecten and SPLC) with the LPSC, subject to Applicable Law and any approvals or notice required by a Governmental Authority (including the LPSC), with respect to crude oil that is: nominated for transportation (i) through the 20” pipeline that is part of the Delta Assets to the connection to the 12” Aflak pipeline that is owned by SPLC, and (ii) through the 12” Aflak pipeline for delivery to Houma, Louisiana, on and after the Effective Time (the “ Applicable Production ”).  Pursuant to the joint tariff agreement, SPLC (or its successor, assign, or designee) shall collect any transportation revenue attributable to the Applicable Production, and SPLC shall remit or pay to Pecten (or its successor, assign, or designee) a portion of such transportation revenue from SPLC, initially based on the allocation of the transportation revenue for the movements described in (i) and (ii) above in effect immediately prior to the Effective Time. 

In addition to the foregoing, Pecten agrees as follows: (i) that, for the pipelines that are part of the Delta Pipeline System for which SPLC or one of SPLC’s Affiliates has tariffs on file with a regulatory agency, SPLC shall or shall cause its Affiliate to cancel such tariffs, such cancellation(s) to be effective prior to or at the Effective Time; and (ii) Pecten will file its own tariff(s) for such pipelines to be effective as of, or as soon as reasonably possible following, the Effective Time, if required by Applicable Law to do so.

ARTICLE VI     
TAX MATTERS

(a)     The Sellers shall be jointly and severally liable for, and shall each indemnify, defend and hold harmless the Purchasers from any liability for (i) Taxes of any of Sellers (and their respective Affiliates other than SHLX and its subsidiaries) and (ii) Taxes imposed on or incurred by or with respect to the Assets attributable to any taxable period ending on or prior to the Closing Date or portion thereof to the extent occurring on or prior to the Closing Date.

(b)     The Purchasers shall be jointly and severally liable for any Taxes imposed on or incurred by or with respect to the Assets attributable to any taxable period beginning after the Closing Date or portion thereof to the extent occurring after the Closing Date.

(c)     Whenever it is necessary for purposes of this Article VI to determine the amount of any Taxes imposed on or incurred by or with respect to the Assets for a taxable period beginning before and ending after the Closing Date which is allocable to the period ending on or prior to the Closing Date and the allocation is not otherwise prescribed by Applicable Law or agreement in effect as of the date hereof, such amount shall be deemed to be the amount of such Tax for the entire Tax period multiplied by a fraction, the numerator of which is the number of days in the Tax period ending on (and including) the Closing Date and the denominator of which is the number of days in the entire Tax period.

(d)     If SHLX or any Purchaser receives a refund of any Taxes that any of the Sellers is responsible for hereunder, or if any Seller receives a refund of any Taxes that SHLX or any Purchaser is responsible for hereunder, the party receiving such refund shall, within ninety (90) days after receipt of such refund, remit it to the party which has responsibility for such Taxes hereunder. The parties shall cooperate in order to take all necessary and reasonable steps to claim any such refund.

(e)     For federal income tax purposes, the parties agree to report any payments with respect to Section 6.1 , ‎ Section 8.1 and ‎Section 8.2 as an adjustment to the Consideration.

(a)     The parties will cooperate fully with each other regarding Tax matters and the preparation and filing of Tax Returns (including the execution of appropriate powers of attorney) and will make available to the other as reasonably requested all information, records and documents relating to Taxes governed by this Agreement until the expiration of the applicable statute of limitations or extension thereof or the conclusion of all audits, appeals or litigation with respect to such Taxes.

Any transfer, documentary, sales, use, stamp, registration and other similar Taxes and/or fees arising out of or in connection with the transactions effected pursuant to this Agreement (each such Tax or fee, a “ Transfer Tax ”) shall be borne by the party on whom such obligation is primarily imposed by Applicable Law; provided, however, that SHLX shall bear any Transfer Tax for which SHLX is jointly and severally liable, and for which no other party is primarily liable, under Applicable Law. The party responsible for a Transfer Tax pursuant to this Section 6.3 shall file all necessary Tax Returns and other documentation with respect to such Transfer Tax. If required by Applicable Law, SPLC and SHLX shall, and shall cause their respective Affiliates to, join in the execution of any such Tax Returns and other documentation. The parties shall cooperate to establish eligibility for any applicable exemption from any Transfer Tax.

The parties will use commercially reasonable efforts to agree upon an allocation of the Consideration for the Assets for U.S. federal income tax purposes in compliance with the principles of Section 1060 of the Code, and the Treasury Regulations thereunder.

In the event of a conflict between the provisions of this Article VI and any other provisions of this Agreement, the provisions of this Article VI shall control.

ARTICLE VIII     
INDEMNIFICATION

Subject to the limitations set forth in this Agreement, the Sellers, jointly and severally, shall indemnify, defend and hold SHLX, its subsidiaries (including Operating, Pecten, and Sand Dollar) and their respective security holders, directors, officers, and employees, and the officers, directors and employees of the General Partner, but otherwise excluding the Sellers, and their respective Affiliates (the “ SHLX Indemnified Parties ”), harmless from and against any and all Damages suffered or incurred by any SHLX Indemnified Party as a result of or arising out of (a) any breach or inaccuracy of a representation or warranty of a Seller in this Agreement, (b) any breach of any agreement or covenant on the part of a Seller made under this Agreement or in connection with the transactions contemplated hereby or thereby, and (c) any costs or damages arising out of the NBR Line Lease (including termination of same in accordance with Section 5.4 ). 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, subject to the other limitations set forth in this Agreement, including this Article VIII , seek indemnification from any one or more of the Sellers.

Subject to the limitations set forth in this Agreement, the Purchasers, jointly and severally, shall indemnify, defend and hold the Sellers and their respective Affiliates (other than any of SHLX Indemnified Parties) and their respective securityholders, directors, officers, agents, representatives and employees (the “ Seller Indemnified Parties ”) harmless from and against any and all Damages suffered or incurred by the Seller Indemnified Parties as a result of or arising out of (a) any breach or inaccuracy of a representation or warranty of a Purchaser in this Agreement or (b) any breach of any agreement or covenant on the part of a Purchaser made under this Agreement or in connection with the transactions contemplated hereby or thereby. Any indemnification provided pursuant to this Agreement shall not be duplicative of any indemnification provided pursuant to the Omnibus Agreement.

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 the Sellers set forth in Section 3.7 (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 the Sellers set forth in ‎ Section 3.8 (Environmental Matters) shall terminate and expire on the third (3rd) anniversary of the Closing Date, (c) the representations and warranties of the Sellers set forth in ‎ Section 3.1 (Organization), ‎ Section 3.2 (Authority and Approval), ‎and ‎ Section 3.12 (Brokerage Arrangements) shall terminate and expire on the second (2 ^nd ) anniversary of the Closing Date, and (d) the representations and warranties of the Purchasers set forth in Section 4.1 (Organization and Existence), Section 4.2 (Authority and Approval) and

Section 4.4 (Brokerage Arrangements) shall terminate and expire on the second (2 ^nd ) anniversary of the Closing Date. After a representation and warranty has terminated and expired, no indemnification shall or may be sought pursuant to this Article VIII on the basis of that representation and warranty by any Person who would have been entitled pursuant to this Article VIII to indemnification on the basis of that representation and warranty prior to its termination and expiration, provided that in the case of each representation and warranty that shall terminate and expire as provided in this Section 8.3 , no claim presented in writing for indemnification pursuant to this Article VIII on the basis of that representation and warranty prior to its termination and expiration shall be affected in any way by that termination and expiration. 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.

(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 following receipt of notice from the indemnified party of a proceeding for which such person may be entitled to indemnification hereunder to assume control of 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 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. Until the indemnifying party so assumes control of the defense of any such claims, the indemnified party or indemnified parties may control all aspects of the defense of any such claims.

(c)     If the indemnifying party assumes the defense of any claim in respect of which an indemnified party intends to or has asserted a claim for indemnification under this Agreement, then such 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.

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.

(a)     To the extent that SHLX Indemnified Parties would otherwise be entitled to indemnification for Damages pursuant to Section 8.1(a) , the Sellers, jointly and severally, shall be liable for Damages pursuant to Section 8.1(a) only if (i) the Damages with respect to any individual claim pursuant to Section 8.1(a) exceed One Hundred Thousand Dollars ($100,000) (the “ Minimum Claim Amount ”) and (ii) the Damages for all claims pursuant to Section 8.1(a) exceed, in the aggregate, One Million Dollars ($1,000,000) (the “ Deductible Amount ”), and then the Sellers, jointly and severally, shall be liable only for Damages pursuant to Section 8.1(a) to the extent of any excess over the Deductible Amount. In no event shall the Sellers’ aggregate liability to SHLX Indemnified Parties under Section 8.1 exceed Sixty-Three Million Dollars ($63,000,000) (the “ Ceiling Amount ”).
