Calculation of Filing Fee

Transaction value*	Amount of filing fee**
$9,244,293.00	$1,008.55

* Estimated for purposes of calculating the amount of the filing fee only. The amount assumes the purchase of all outstanding common units representing limited partner interests (the “Common Units”) of Sanchez Midstream Partners LP (“SNMP”) not owned by Stonepeak Catarina Holdings, LLC (“Stonepeak”) and its affiliates at a purchase price of $0.62 per Common Unit, net to the seller in cash, which is equal to the price which would be paid if Stonepeak caused the exercise of the limited call right described in this Transaction Statement on Schedule 13E-3, including the exhibits attached hereto. On December 8, 2020, 19,953,880 Common Units were outstanding of which 5,043,730 are owned by Stonepeak and its affiliates. Accordingly, this calculation assumes the purchase of 14,910,150 Common Units, the maximum number of Common Units that may be acquired in the transactions.

** The amount of the filing fee is calculated in accordance with Rule 0-11 of the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory #1 for Fiscal Year 2021 issued by the Securities and Exchange Commission, equals $109.10 per million dollars of the transaction value.

¨ Check the box if any part of the fee is offset as provided by Rule 0-11(a)(2) and identify the filing with which the offsetting fee was previously paid. Identify the previous filing by registration statement number, or the Form or Schedule and the date of its filing.

Introduction

This Transaction Statement on Schedule 13E-3 (as amended from time to time, this “Transaction Statement”), together with the exhibits hereto, is being jointly filed with the United States Securities and Exchange Commission (the “SEC”) pursuant to Section 13(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by (i) Stonepeak Catarina Holdings, LLC, a Delaware limited liability company (“Stonepeak Catarina” and, together with its subsidiaries, other than SNMP (as defined herein) “Stonepeak”), SP Common Equity Subsidiary LLC, a Delaware limited liability company, Stonepeak Texas Midstream Holdco LLC, a Delaware limited liability company, Stonepeak Catarina Upper Holdings LLC, a Delaware limited liability company, Stonepeak Infrastructure Fund (Orion AIV) LP, a Delaware limited partnership, Stonepeak Associates LLC, a Delaware limited liability company, Stonepeak GP Holdings LP, a Delaware limited partnership, Stonepeak GP Investors LLC, a Delaware limited liability company, Stonepeak GP Investors Manager LLC, a Delaware limited liability company, Michael Dorrell, a citizen of the United States of America, and Trent Vichie, a citizen of the United States of America, (ii) Sanchez Midstream Partners GP LLC, a Delaware limited liability company and the general partner of SNMP (the “General Partner”), and (iii) Sanchez Midstream Partners LP, a Delaware limited partnership (“SNMP”).

This Transaction Statement relates to the execution of a letter agreement, dated November 16, 2020 (the “Common Unit PIK Distribution Agreement”), pursuant to which Stonepeak Catarina, SNMP and the General Partner agreed that future quarterly distributions on the Class C Preferred Units representing limited partner interests in SNMP (“Class C Preferred Units”) are payable, at Stonepeak Catarina’s election, in common units representing limited partner interests in SNMP (“Common Units”) (any such quarterly distribution that is paid in Common Units, a “Common Unit PIK Distribution”) in lieu of a quarterly distribution paid in kind with additional Class C Preferred Units (such additional units, “Class C Preferred PIK Units”). Stonepeak Catarina agreed to receive the quarterly distribution on its Class C Preferred Units with respect to the third quarter of 2020 (the “Third Quarter Common Unit PIK Distribution”) in Common Units, subject to certain conditions.

As of December 8, 2020, there were 19,953,880 outstanding Common Units, and Stonepeak owned (i) 5,043,730 Common Units, representing approximately 25.3% of the outstanding Common Units, (ii) all of the issued and outstanding Class C Preferred Units, (iii) a warrant (the “Warrant”) that entitles Stonepeak Catarina to receive junior securities of SNMP (including Common Units) representing 10% of all junior securities deemed outstanding when exercised, (iv) the non-economic general partner interest in SNMP and (v) all of SNMP’s incentive distribution rights. Following (x) the Third Quarter Common Unit PIK Distribution, Stonepeak will own 27,318,599 Common Units (32,118,948 Common Units assuming the full exercise of the Warrant following the Third Quarter Common Unit PIK Distribution), representing approximately 64.7% (68.3% assuming the full exercise of the Warrant following the Third Quarter Common Unit PIK Distribution) of the outstanding Common Units.

At any time Stonepeak holds more than 80% of the outstanding Common Units, whether as a result of Common Unit PIK Distributions, the exercise of the Warrant or other acquisition of Common Units, which could occur as early as the first quarter of 2021 (based on the price per Common Unit as of the date of this Transaction Statement), and completes the Stonepeak LCR Transfer (as defined herein), Stonepeak will be able to cause the General Partner or a controlled affiliate of the General Partner to exercise the limited call right (the “limited call right”) provided for in Section 15.1 of the Third Amended and Restated Agreement of Limited Partnership of SNMP (the “Partnership Agreement”) to purchase all outstanding Common Units (other than Common Units held by the General Partner or its controlled affiliates), at a price per Common Unit determined pursuant to Section 15.1 of the Partnership Agreement. As of the date of this Transaction Statement, the General Partner and its controlled affiliates do not own any Common Units.

The Common Unit PIK Distributions, the potential exercise of the Warrant and, if exercised, the exercise of the limited call right are referred to in this Transaction Statement as the “Transactions.”

As of the date of this Transaction Statement, Stonepeak has not acquired any Common Units pursuant to the Common Unit PIK Distribution Agreement, has not exercised the Warrant and has not caused the exercise of the limited call right. However, the execution of the Common Unit PIK Distribution Agreement may be deemed to constitute a step towards one or more transactions that may constitute a “Rule 13e-3 transaction” under the rules and regulations of the SEC pursuant to the Exchange Act. Accordingly, no Common Unit PIK Distribution will occur until at least 30 days after the initial filing with the SEC of this Transaction Statement. This Transaction Statement is being provided to holders of Common Units (“Common Unitholders”) in order to satisfy the requirements of Rule 13e-3 in connection with the Common Unit PIK Distribution Agreement.

Attached hereto as Exhibit (a)(3) is a Disclosure Statement (the “Disclosure Statement”) that provides disclosure concerning the Transactions.
