the Parties are unable to resolve such dispute within 30 days, the Parties shall retain a mutually agreeable, nationally recognized accounting firm (that does not have a material relationship with any of the Parties, or any of their respective Affiliates) (the “Tax Allocation Referee”) to resolve the disputed items.  Notwithstanding anything to the contrary herein, the Parties (and the Tax Allocation Referee, if applicable) shall resolve all disputed items no later than 30 days after retaining the Tax Allocation Referee.  Upon resolution of the disputed items, the allocation reflected on the Allocation Statement shall be adjusted to reflect such resolution.  The fees and expenses payable to the Tax Allocation Referee shall be split equally between Buyer and the SN Parties.  The Parties agree to (i) be bound by the Allocation Statement and (ii) act in accordance with the Allocation Statement in the preparation, filing and audit of any Tax Return (including filing Form 8594 with a federal income Tax Return for the taxable year that includes the date of the Closing).  Neither Buyer nor the SN Parties shall agree to any proposed adjustment to the Allocation Statement by any Tax Authority without first giving the other Party prior written notice; provided, however, that nothing contained herein shall prevent Buyer or the SN Parties from settling any proposed deficiency or adjustment by any Tax Authority based upon or arising out of the Allocation Statement, and neither Buyer nor the SN Parties shall be required to litigate before any court any proposed deficiency or adjustment by any Tax Authority challenging such Allocation Statement.

Section 7.1            Further Assurances.  After the Closing, each Party shall use its commercially reasonable efforts to take such further actions, including obtaining or transferring to the other Party all necessary Permits, Consents, orders and Contracts and executing and causing its Affiliates to execute such further documents, as may be necessary or reasonably requested by another Party in order to effectuate the intent of this Agreement and to provide such other Party with the intended benefits of this Agreement, including, without limitation, (i) Seller executing or causing its Affiliates to execute any further documents, as may be necessary to transfer, upon completion, all legal right, title and interest in and to the Assets Under Construction to Buyer, in each case without the payment of any consideration in addition to the amount contemplated in Section 2.3 hereof and (ii) transferring or amending, as applicable, appropriate T-4, R-3 and R-5 permits, filings and reports with the Texas Railroad Commission and air permits with the Texas Commission on Environmental Quality from SN Operating, LLC to the Company or Buyer’s designee.  Without limiting the generality of the foregoing, the Parties acknowledge that the Parties have used their good faith efforts to identify all of the assets and operations to be purchased by Buyer in connection with this Agreement.  However, due to the age of some of the assets or operations and the difficulties in locating appropriate data with respect to some of the assets included in these operations, it is possible that some of the assets intended to be purchased ultimately by Buyer were not identified and therefore are not transferred (directly or indirectly) to Buyer as of the Closing Date.  To the extent that any assets owned by an SN Party or one of its Affiliates (other than the Company) as of the Effective Date were not identified but form an integral part of the assets and operations of the Company or the Midstream Assets are subsequently identified, then the intent of the Parties is that all such unidentified assets are intended to be conveyed to Buyer pursuant to this Agreement. To the extent any such assets are identified at a later date, the Parties shall take all appropriate action required in order to convey such assets to the Company without the payment of any consideration in addition to the amount contemplated in Section 2.3 hereof.  Likewise, to the extent that any assets or operations that are indirectly conveyed to Buyer hereunder are later identified by the Parties as assets and operations that the Parties did not intend to convey to

23

Buyer, the Parties shall take all appropriate action required to convey such assets and operations to Seller or its Affiliates (as directed by Seller).

Section 7.2            Tax Matters.

(a)             Taxes.  The Parties agree that the income related to the Company Assets for the period up to and including the Closing Date will be reflected on the federal income Tax Return of Seller and that Seller shall bear the liability for any Taxes associated with such income.  The Parties further agree that the income related to the Company Assets for the period after the Closing Date will be reflected on the federal income Tax Return of Buyer and that the partners of Buyer shall bear the liability for any Taxes associated with such income.

(b)             Proration of 2015 Ad Valorem Taxes.  Ad valorem taxes relating to the Company Assets for the year ending December 31, 2015 shall be prorated on a daily basis between Buyer, on the one hand, and Seller, on the other hand, with Buyer responsible for the prorated portion of such taxes for such period (for purposes of this Section 7.2(b), “period” means the period beginning on the assessment date for ad valorem taxes through the day before the next assessment date for such taxes) up to and including the Closing Date and Seller responsible for the prorated portion of such taxes after the Closing Date.  The Party that receives the ad valorem tax billing 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 applicable Tax Authorities

(c)             Transaction Taxes.  All sales, use, transfer, filing, recordation, registration and similar Taxes arising from or associated with the transactions contemplated by this Agreement (not including, for the sake of clarity, the Gathering Agreement) other than Taxes based on income (“Transaction Taxes”), shall be borne 50% by Seller and 50% by Buyer.  To the extent under Applicable Law the transferee is responsible for filing Tax Returns in respect of Transaction Taxes, Buyer shall prepare and file all such Tax Returns.  The Parties shall provide such certificates and other information and otherwise cooperate to the extent reasonably required to minimize Transaction Taxes.  The Party that is not responsible under Applicable Law for paying the Transaction Taxes shall pay its share of the Transaction Taxes to the responsible Party prior to the due date of such Taxes.

(d)             Cooperation on Tax Matters.  Following the Closing Date, the Parties shall cooperate fully with each other and shall make available to the other, as reasonably requested and at the expense of the requesting Party, and to any Governmental Authority responsible for the administration of any Tax, all information, records or documents relating to Tax liabilities or potential Tax liabilities of the Company for all periods at or prior to the Effective Date and any information which may be relevant to determining the amount payable hereunder, and shall preserve all such information, records and documents at least until the expiration of any applicable statute of limitations or extensions thereof.

Section 7.3            Cooperation for Litigation and Other Actions.  Each Party shall cooperate reasonably with each other Party, at the requesting Party’s expense (but including only out-of-

24

pocket expenses to unaffiliated third parties, photocopying and delivery costs and not the costs incurred by any Party for the wages or other benefits paid to its officers, directors or employees), in furnishing reasonably available information, testimony and other assistance in connection with any Claims or other disputes involving any of the Parties hereto (other than in connection with disputes between the Parties).

Section 7.4            Retention of and Access to Books and Records.

(a)             On or before the Closing Date, the SN Parties will deliver or cause to be delivered to Buyer, the Books and Records that are in the possession or control of the SN Parties or their Affiliates.

(b)             Buyer agrees to afford the SN Parties and their Affiliates and their respective accountants, counsel and other designated individuals, during normal business hours, upon reasonable request, at a mutually agreeable time, full access to and the right to make copies of the Books and Records at no cost to the SN Parties or their Affiliates (other than for reasonable out-of-pocket expenses); provided that such access will not be construed to require the disclosure of Books and Records that would cause the waiver of any attorney-client, work product or like privilege; provided, further, that in the event of any litigation, nothing herein shall limit any Party’s rights of discovery under Applicable Law. Without limiting the generality of the preceding sentences, Buyer agrees to provide SN Parties and their Affiliates reasonable access to and the right to make copies of the Books and Records after the Closing for the purposes of assisting SN Parties and their Affiliates (i) in complying with the SN Parties’ obligations under this Agreement; (ii) in adjusting, prorating and settling the charges and credits provided for under this Agreement; (iii) in preparing Tax Returns; (iv) in responding to or disputing any tax audit; (v) in asserting, defending or otherwise dealing with any Claim or dispute, known or unknown, under this Agreement; and (vi) in asserting, defending or otherwise dealing with any third-party Claim or dispute by or against SN Parties and their Affiliates relating to the Company.

(c)             Notwithstanding the foregoing provisions of this Section or anything else to the contrary in this Agreement, with respect to any Books and Records the transfer or other disclosure of which to Buyer would waive (or would reasonably risk the waiver of) any attorney/client, work product, tax practitioner, audit or other privilege relating to the Retained Obligations, the SN Parties shall not be required to transfer such Books and Records (or any copies thereof) to Buyer until the appropriate Parties enter into a mutually-agreed joint defense agreement to allow for the sharing of common defense privileged materials.

Section 7.5            SEC Matters.  The SN Parties acknowledge that Buyer may be required to include financial statements relating to the Company (“SEC Financial Statements”) in documents filed with the SEC by Buyer pursuant to the Securities Act or the Exchange Act, and that such SEC Financial Statements may be required to be audited.  In that regard, the SN Parties shall reasonably cooperate with Buyer, and provide Buyer reasonable access to such records (to the extent such information is available) and personnel of the SN Parties and the Company as Buyer may reasonably request to enable Buyer, and its representatives and accountants, at Buyer’s sole cost and expense, to create and audit any SEC Financial Statements that Buyer deems necessary.  The SN Parties hereby consent to the inclusion or incorporation by reference

25

of the SEC Financial Statements in any registration statement, report or other document of Buyer or any of its Affiliates to be filed with the SEC in which Buyer or its Affiliate reasonably determines that the SEC Financial Statements are required to be included or incorporated by reference to satisfy any rule or regulation of the SEC or to satisfy relevant disclosure obligations under the Securities Act or the Exchange Act.  Upon request of Buyer, the SN Parties shall use commercially reasonable efforts to cause the external audit firm that audits the SEC Financial Statements to consent to the inclusion or incorporation by reference of its audit opinion with respect to any applicable audited financial statements of Buyer in any such registration statement, report or other document and to provide customary comfort letters as required by Buyer’s underwriters.  The SN Parties shall provide Buyer and its independent accountants with access to (i) any audit work papers of the SN Parties’ independent accountants and (ii) any management representation letters provided by the SN Parties to the SN Parties’ independent accountants.  Notwithstanding the foregoing, nothing herein shall expand the SN Parties’ representations, warranties, covenants or agreements set forth in this Agreement or give Buyer, its Affiliates or any third party any rights to which it is not entitled hereunder.  Buyer hereby releases the Seller Indemnified Parties from, and shall fully protect, defend, indemnify and hold the Seller Indemnified Parties harmless from and against, in each case, any and all Losses (including costs of investigation and attorneys’ and experts’ fees and expenses) relating to, arising out of or connected with, directly or indirectly, any actions, representations or certifications of the SN Parties and their Affiliates personnel or auditors with respect to the access, records and cooperation provided pursuant to this Section 7.5, or Buyer’s use of information contained in such records or the inclusion of such financial records in any debt or equity offering documents or related materials.  THESE INDEMNITY AND DEFENSE OBLIGATIONS APPLY REGARDLESS WHETHER SUCH LOSSES ARE ATTRIBUTABLE TO OR ARISE OUT OF, SOLELY OR IN PART, THE SOLE, ACTIVE, GROSS, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY ANY OF THE SELLER INDEMNIFIED PARTIES; PROVIDED HOWEVER THE FOREGOING INDEMNITY AND DEFENSE OBLIGATIONS SHALL NOT APPLY WITH RESPECT TO THE WILLFUL MISCONDUCT OF ANY SELLER INDEMNIFIED PARTY.

Any failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it, he, or she may have to such Indemnified Party under this Article XI unless the failure to give such notice materially and adversely prejudices the Indemnifying Party. The Indemnifying Party shall have the right to assume control of the defense of, settle, or otherwise dispose of such third-party action on such terms as it deems appropriate; provided, however, that:

(a)             The Indemnified Party shall be entitled, at its own expense, to participate in the defense of such third-party action (provided, however, that the Indemnifying Party shall pay the attorneys’ fees of the Indemnified Party if (i) the employment of separate counsel shall have been authorized in writing by the Indemnifying Party in connection with the defense of such third-party action; (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to the Indemnified Party to have charge of such third-party action; (iii) the Indemnified Party shall have reasonably concluded that there may be defenses available to such Indemnified Party that are different from or additional to those available to the Indemnifying Party; or (iv) the Indemnified Party’s counsel shall have advised the Indemnified Party in writing, with a copy delivered to the Indemnifying Party, that there is a material conflict of

30

interest that could violate applicable standards of professional conduct to have common counsel);

(b)                                       The Indemnifying Party shall obtain the prior written approval of the Indemnified Party before entering into or making any settlement, compromise, admission or acknowledgment of the validity of such third-party action or any liability in respect thereof if, pursuant to or as a result of such settlement, compromise, admission, or acknowledgment, injunctive or other equitable relief would be imposed against the Indemnified Party or if, in the opinion of the Indemnified Party, such settlement, compromise, admission or acknowledgment could have a material adverse effect with respect to the Indemnified Party;

(c)                                        The Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement without the consent of the Indemnified Party that does not include as an unconditional term thereof the giving by each claimant or plaintiff to the Indemnified Party of a release from all liability in respect of such third-party action; and

(d)                                       The Indemnifying Party shall not be entitled to control (but shall be entitled to participate at its own expense in the defense of), and the Indemnified Party shall be entitled to have sole control over, the defense or settlement, compromise, admission, or acknowledgment of any third-party action (i) as to which the Indemnifying Party fails to assume the defense within a reasonable length of time or (ii) to the extent the third-party action seeks an order, injunction, or other equitable relief against the Indemnified Party which, if successful, would materially adversely affect the business, operations, assets, or financial condition of the Indemnified Party; provided, however, that the Indemnified Party shall make no settlement, compromise, admission, or acknowledgment that would give rise to liability on the part of any Indemnifying Party without the prior written consent of such Indemnifying Party.

The Parties shall extend reasonable cooperation in connection with the defense of any third-party action pursuant to this Article XI and, in connection therewith, shall furnish such records, information, and testimony and attend such conferences, discovery proceedings, hearings, trials, and appeals as may be reasonably requested.

Section 11.3                             Direct Claims.  In any case in which an Indemnified Party seeks indemnification hereunder which is not subject to Section 11.2 because no third-party action is involved, the Indemnified Party shall notify the Indemnifying Party in writing of any Indemnified Costs which such Indemnified Party claims are subject to indemnification under the terms hereof.  Subject to the limitations set forth in Section 11.4(a), the failure of the Indemnified Party to exercise promptness in such notification shall not amount to a waiver of such claim unless the resulting delay materially prejudices the position of the Indemnifying Party with respect to such claim.

Section 11.4                             Limitations.  The following provisions of this Section 11.4 shall limit the indemnification obligations hereunder:

(a)                                       The Indemnifying Party shall not be liable for any Indemnified Costs pursuant to this Article XI unless a written claim for indemnification in accordance with Section 11.2 or Section 11.3 is given by the Indemnified Party to the Indemnifying Party with respect

31

(b)                                       Except as set forth in this Agreement, an Indemnified Party will not be entitled to any Indemnified Costs with respect to any individual Claim that does not equal or exceed $150,000 (the “Individual Indemnity Threshold”) and all such Claims that equal or exceed the Individual Indemnity Threshold must collectively also exceed the Indemnity Deductible, and thereafter, the Indemnified Party shall only be entitled to indemnity for the amount in excess of the Indemnity Deductible, subject to the limitations set forth in this Agreement.  Except as set forth below, the maximum aggregate liability of the SN Parties under Section 11.1 of this Agreement shall not exceed the Indemnity Cap.  Except as set forth below, the maximum aggregate liability of Buyer under Section 11.1 of this Agreement shall not exceed the Indemnity Cap.

(c)                                        The limitations set forth above in this Section 11.4 shall not apply to any claim for indemnification under Section 11.1 with respect to any breach of (i) the Fundamental Representations or (ii) the indemnification obligations set forth in this Article XI of this Agreement.

(d)                                       Each Party acknowledges and agrees that, after the Closing Date, except as otherwise set forth in Article XII of this Agreement, Buyer’s and the other Buyer Indemnified Parties’ and the SN Parties’ and the other Seller Indemnified Parties’ sole and exclusive remedy with respect to the Indemnified Costs shall be in accordance with, and limited by, the provisions set forth in this Article XI.

(e)                                        For purposes of determining any Losses resulting from a breach of any of the SN Parties’ representations and warranties contained in Article III or Article IV of this Agreement for which Buyer Indemnified Parties would be entitled to indemnification, any dollar or materiality qualifications in the SN Parties’ representations and warranties shall be disregarded.

Section 11.5                             Tax Treatment of Payment of Indemnity Costs.  The SN Parties and Buyer agree that any payment of Indemnified Costs made hereunder will be treated by the Parties on their Tax Returns as an adjustment to the Purchase Price.

Section 11.6                             Express Negligence Rule.  THE FOREGOING INDEMNITIES ARE INTENDED TO BE ENFORCEABLE AGAINST THE PARTIES IN ACCORDANCE WITH THE EXPRESS TERMS AND SCOPE THEREOF NOTWITHSTANDING ANY EXPRESS NEGLIGENCE RULE OR ANY SIMILAR DIRECTIVE THAT WOULD PROHIBIT OR OTHERWISE LIMIT INDEMNITIES BECAUSE OF THE SOLE, CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE, STRICT LIABILITY OR FAULT OF ANY OF THE INDEMNIFIED PARTIES.

Section 12.5                             Governing Law; Consent to Jurisdiction; Enforcement.

(a)                                       This Agreement shall be subject to and governed by the laws of the State of Texas, excluding any conflicts-of-law rule or principle that might refer the construction or interpretation of this Agreement to the laws of another state.

(b)                                       The Parties hereby irrevocably submit to the exclusive jurisdiction of the state and federal courts located in the State of Texas over any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby, and each Party irrevocably agrees that all claims in respect of such dispute or proceeding shall be brought, heard and determined only in such courts. The Parties hereby irrevocably waive, to the fullest extent permitted by Applicable Law, any objection which they may now or hereafter have to the venue of any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each Party agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Applicable Law.

(c)                                        The Parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each of the Parties shall be entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any state or federal court located in the State of Texas, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the Parties hereto further hereby waives (i) any defense in any action for specific performance that a remedy at law would be adequate and (ii) any requirement under any law to post security as a prerequisite to obtaining equitable relief.

Section 12.6                             Confidentiality.

(a)                                       Obligations. Each Party shall use commercially reasonable efforts to retain the other Party’s Confidential Information in confidence and not disclose the same to any third party nor use the same, except as authorized by the disclosing Party in writing or as expressly permitted in this Section 12.6.  Each Party further agrees to take the same care with

35

the other Party’s Confidential Information as it does with its own, but in no event less than a reasonable degree of care.

(b)                                       Required Disclosure. Notwithstanding Section 12.6(a) above, if the receiving Party becomes legally compelled to disclose the Confidential Information by a court, Governmental Authority or Applicable Law, including the rules and regulations of the Securities and Exchange Commission, or is required to disclose pursuant to the rules and regulations of any national securities exchange upon which the receiving Party or its parent entity is listed, any of the disclosing Party’s Confidential Information, the receiving Party shall promptly advise the disclosing Party of such requirement to disclose Confidential Information as soon as the receiving Party becomes aware that such a requirement to disclose might become effective, in order that, where possible, the disclosing Party may seek a protective order or such other remedy as the disclosing Party may consider appropriate in the circumstances.  The receiving Party shall disclose only that portion of the disclosing Party’s Confidential Information that it is required to disclose and shall cooperate with the disclosing Party in allowing the disclosing Party to obtain such protective order or other relief.

(c)                                        Return of Information. Upon written request by the disclosing Party, all of the disclosing Party’s Confidential Information in whatever form shall be returned to the disclosing Party upon termination of this Agreement or destroyed with destruction certified by the receiving Party, without the receiving Party retaining copies thereof except that one copy of all such Confidential Information may be retained by a Party’s legal department for purposes of resolving any dispute that may arise hereunder or for complying with Applicable Law or the rules of any securities exchange applicable to the Party, and the receiving Party shall be entitled to retain any Confidential Information in electronic form stored on automatic computer back-up archiving systems during the period such backup or archived materials are retained under such Party’s customary procedures and policies; provided, however, that any Confidential Information retained by the receiving Party shall be maintained subject to confidentiality pursuant to the terms of this Section 12.6, and such archived or back-up Confidential Information shall not be accessed except as required by Applicable Law.

(d)                                       Receiving Party Personnel. The receiving Party will limit access to the Confidential Information of the disclosing Party to those of its employees, attorneys, representatives and contractors that have a need to know such information in order for the receiving Party to exercise or perform its rights and obligations under this Agreement (the “Receiving Party Personnel”).  The Receiving Party Personnel who have access to any Confidential Information of the disclosing Party will be made aware of the confidentiality provision of this Agreement, and will be required to abide by the terms thereof.

(e)                                        Survival. The obligation of confidentiality under this Section 12.6 shall survive until the second anniversary the Closing Date.

Section 12.7                             Parties in Interest.  This Agreement shall be binding upon and inure solely to the benefit of each Party hereto and their successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to confer upon any other Person (other than the Indemnified Parties with respect to Article XI and the Parties’ respective Affiliates with respect

36

to Section 12.1) any rights or remedies of any nature whatsoever under or by reason of this Agreement.

Section 12.8                             Assignment of Agreement.  Neither this Agreement nor any of the rights, interests, or obligations hereunder may be assigned by any Party without the prior written consent of the other Party hereto.

Section 12.9                             Captions.  The captions in this Agreement are for purposes of reference only and shall not limit or otherwise affect the interpretation hereof.

Section 12.10                      Counterparts.  This Agreement may be executed in one or more counterparts (including by facsimile or portable document format (pdf)) for the convenience of the Parties hereto, each of which counterparts will be deemed an original, but all of which counterparts together will constitute one and the same agreement.

Section 12.11                      Integration.  This Agreement supersedes any previous understandings or agreements among the Parties, whether oral or written, with respect to their subject matter. This Agreement contains the entire understanding of the Parties with respect to the subject matter hereof and thereof. No understanding, representation, promise or agreement, whether oral or written, is intended to be or shall be included in or form part of this Agreement unless it is contained in a written amendment hereto or thereto and executed by the Parties hereto or thereto after the date of this Agreement. For the sake of clarity, the representations, warranties and covenants set forth in this Agreement shall not be limited by the ▇▇▇▇ of Sale.

Section 12.12                      Amendment; Waiver.  This Agreement may be amended only in a writing signed by all Parties. Any waiver of rights hereunder must be set forth in writing. A waiver of any breach or failure to enforce any of the terms or conditions of this Agreement shall not in any way affect, limit or waive any Party’s rights at any time to enforce strict compliance thereafter with every term or condition of this Agreement. Any amendment or waiver executed by any of the Parties or their respective subsidiaries shall not be effective unless and until the execution of such amendment or waiver has been approved by, with respect to Buyer, the conflicts committee of the board of directors of the General Partner, and with respect to the SN Parties, the audit committee of the board of directors of SN.

Section 12.13                      Buyer Right of First Offer.

(a)                                       As provided in and subject to the other provisions of this Section 12.13, SN hereby grants to Buyer, for a period of 15 years after the Closing Date, a right of first offer on the ROFO Assets to the extent that SN or any SN Subsidiary (a “Transferring Entity”) proposes to Transfer all or any part of such ROFO Assets to any Person that is not an Affiliate of SN.

(b)                                       If any Transferring Entity proposes to Transfer all or any portion of any ROFO Asset (other than to SN or an Affiliate thereof), SN shall, or shall to the extent it has the legal right, cause the applicable Transferring Entity to, prior to entering into any such transaction, first give written notice to Buyer (the “ROFO Notice”) of its intention to enter into such transaction. The ROFO Notice shall include a description of the ROFO Assets which the

37

Transferring Entity proposes to Transfer as would be reasonably necessary for Buyer to make an offer to purchase the ROFO Assets from the applicable Transferring Entity.

(c)                                        Buyer shall have 20 days following receipt of the ROFO Notice to propose a bona fide offer to purchase the ROFO Assets from the Transferring Entity that provided such ROFO Notice (the “ROFO Response”).  The ROFO Response shall set forth the material terms and conditions (including, without limitation, the purchase price that Buyer proposes to pay for the ROFO Asset and the other material terms of the purchase) pursuant to which Buyer would be willing and able to enter into a binding agreement for the transaction.  If no ROFO Response is delivered by Buyer within such 20-day period or if Buyer otherwise informs the Transferring Entity that it does not intend to provide a ROFO Response, then Buyer shall be deemed to have waived its right of first offer with respect to such ROFO Asset, and the Transferring Entity shall be free to enter into a transaction with any third party on terms and conditions determined in the sole discretion of the Transferring Entity.

(d)                                       If Buyer submits a ROFO Response which the Transferring Entity is willing to accept, SN shall, or shall to the extent it has the legal right, cause the applicable Transferring Entity to, negotiate in good faith with Buyer with respect to such transaction for a period of 30 days from the date of such ROFO Response (the “Negotiation Period”).  If Buyer submits a ROFO Response which the Transferring Entity is not willing to accept, or if Buyer and the Transferring Entity are unable to reach terms with respect to a definitive agreement within the Negotiation Period, SN and/or the Transferring Entity may enter into an agreement with a third party to Transfer the ROFO Assets described in the ROFO Notice but SN agrees that, without the prior written consent of Buyer, it shall not, or shall to the extent it has the legal right, cause the Transferring Entity to not, enter into a definitive transfer agreement with any third party with respect to such ROFO Assets at any time during the 120-day period commencing from the ROFO Response at a price which is lower than that proposed by Buyer in the ROFO Response and which are on terms which are materially more favorable to such third party than those set forth in the ROFO Response.  If the Transferring Entity does not enter into a definitive agreement with a third party with respect to such a transaction within such 120-day period, then SN shall, or shall to the extent it has the legal right, cause such Transferring Entity to, comply with the provisions of this Section 12.13 again prior to entering into any transaction with respect to such ROFO Assets.  For the avoidance of doubt, the foregoing of this Section 12.13 constitutes a right of first offer (and not a right of first refusal) which entitles Buyer the right to make an initial offer with respect to the Transfer of the ROFO Assets but which does not grant to Buyer the right to match an offer from a third party with respect to the ROFO Assets.

Section 12.14                      Mitigation.  Each Party shall take all reasonable steps, and shall reasonably cooperate with the other Parties in good faith, to mitigate damages in respect of any Claim under Article XI for which it or another Buyer Indemnified Party or Seller Indemnified Party, as applicable, is seeking indemnification and shall use reasonable efforts to avoid any costs or expenses associated with such Claim and, if such costs and expenses cannot be avoided, to minimize the amount thereof.  Further, no Party shall take nor fail to take any action, which action or inaction induces, incentivizes or otherwise is reasonably likely to lead a third party to make a Claim against a Buyer Indemnified Party or Seller Indemnified Party, for which it seeks indemnification under Article XI.  Additionally, if any provision of this Agreement or the Gathering Agreement, if complied with or performed, would result (or has resulted) in any

38

breach or other violation (or is being challenged as a breach or other violation) of any Dedicated Instrument, otherwise conflicts (or is being challenged as conflicting) with any Dedicated Instrument, or would otherwise give (or has otherwise given) rise to a Claim under this Agreement or the Gathering Agreement as a result of such a breach or other violation or conflict (or challenge) with respect to any Dedicated Instrument, each Party shall take all reasonable steps, and shall reasonably cooperate with the other Parties in good faith, to mitigate damages with respect to such a breach or other violation or conflict (or challenge) and to amend this Agreement and/or the Gathering Agreement (and/or enter into other mutually acceptable agreements or arrangements) to the extent necessary to effect the original intent of the Parties and maintain the Parties’ relative economic burdens and benefits, as closely as possible.
