MEMORANDUM OPINION

I. INTRODUCTION

This appeal centers around certain oil and gas properties and leases in Louisiana (the Louisiana Assets). Over the last few decades, the Louisiana Assets have changed hands many times, with the most recent purchaser being Appellants Urban Fund III, LP and Urban Oil and Gas Partners C-1, LP (collectively, Urban). Urban acquired the Louisiana Assets from Appellees Blackbeard Operating East, LLC and Blackbeard Resources, LLC (collectively, Blackbeard). Blackbeard’s predecessors to the Louisiana Assets—a group we will collectively refer to as the Up-Chain Defendants—consist of Appellees Legacy Reserves Operating LP; Legacy Reserves, LP; Revenir Energy Inc. f/k/a Legacy Reserves Inc.;1 Marathon Oil Company; Marathon Oil (East Texas) LP;2 Oxy USA, Inc.; and Kerr-McGee Oil & Gas Onshore LP, in its own capacity and as successor to Sun Exploration and Production Company.

Beginning in 2018, certain landowners in Louisiana filed several environmental lawsuits (the Louisiana Lawsuits) against Urban, Blackbeard, and the Up-Chain Defendants alleging damages sustained from the exploration and production of oil and gas on the Louisiana Assets. The Up-Chain Defendants then tendered demands

1 We will collectively refer to Legacy Reserves Operating LP, Legacy Reserves, LP, and Revenir Energy Inc. f/k/a Legacy Reserves Inc. as Legacy.

2 We will collectively refer to Marathon Oil Company and Marathon Oil (East Texas) LP as Marathon.

for defense and indemnity down the chain. Those tenders were accepted all the way down the chain to Blackbeard, who then tendered its demand for defense and indemnity to Urban. While Urban accepted defense and indemnity for Blackbeard’s direct liability in the Louisiana Lawsuits, it refused to defend and indemnify Blackbeard for the amounts it had paid to defend and indemnify the Up-Chain Defendants.

Urban later filed the underlying declaratory-judgment action seeking certain declarations regarding the various rights and obligations of the parties under the 2018 purchase-and-sale agreement governing Blackbeard’s sale of the Louisiana Assets to Urban (the Blackbeard–Urban PSA). Blackbeard and the Up-Chain Defendants answered and filed their own declaratory-judgment actions regarding Urban’s defense and indemnity obligations. All parties moved for summary judgment, and the trial court denied Urban’s motion; granted Blackbeard’s and the Up-Chain Defendants’ respective motions; awarded Blackbeard damages and attorney’s fees; and awarded the Up-Chain Defendants’ attorney’s fees.

In three issues on appeal, Urban argues that (1) the Blackbeard–Urban PSA does not require it to provide defense and indemnity to the Up-Chain Defendants; (2) because Marathon’s indemnity claims against Legacy were discharged in Legacy’s 2019 bankruptcy case, any defense and indemnity obligations that Urban may owe to Marathon or its predecessors-in-interest have been extinguished; and (3) an anti- assignment clause in an amendment to the Marathon–Legacy PSA renders Legacy’s

purported attempt to transfer defense and indemnity obligations to Blackbeard—and Blackbeard’s purported attempt to transfer such obligations to Urban—void. Because we conclude (1) that the Blackbeard–Urban PSA requires Urban to defend and indemnify Blackbeard for all of its liabilities related to or associated with the conveyed oil-and-gas properties—including Blackbeard’s own defense and liability obligations to the Up-Chain Defendants; (2) that Marathon’s defense and indemnity claims were not discharged in Legacy’s bankruptcy case and that even if they had been discharged, Urban’s own obligations would be unaffected; and (3) that the anti-assignment provision in the amendment to the Marathon–Legacy PSA does not eliminate Urban’s obligations to defend and indemnify Blackbeard for its own obligations to defend and indemnify the Up-Chain Defendants, we affirm the trial court’s judgment.

II. BACKGROUND

A. Sun’s 1985 Sale to Marathon In 1985, Sun sold certain properties that were included within the Louisiana Assets to Marathon pursuant to a partial assignment and bill of sale (the Sun– Marathon PABOS). The Sun–Marathon PABOS contained an indemnification provision providing, in pertinent part, that

[Marathon] hereby agrees to assume all responsibility for said wells . . . , and [Marathon] agrees to protect, defend, indemnify[,] and hold [Sun]

and its employees free and harmless from and against any and all costs, expenses, claims, demands[,] and causes of action of every kind and character arising out of, incident to, or in connection with the abovedescribed leases.

B. Oxy’s 1994 Sale to Marathon In 1994, Oxy sold other properties that were included within the Louisiana Assets to Marathon pursuant to a purchase-and-sale agreement (the Oxy–Marathon PSA). The Oxy–Marathon PSA contained the following indemnification provision:

[Marathon] shall defend, indemnify[,] and hold harmless [Oxy] . . . from any and all losses, claims, demands, suits, damages, expenses, costs, causes of action[,] or judgments of any kind or character with respect to all liabilities and obligations or alleged or threatened liabilities and obligations, including claims for personal injury, illness, disease, wrongful death, damage to property, liability based on strict liability or condition of the Properties being assigned herein . . . , and claims . . . resulting from environmental damage or pollution which arise from, or are attributable to, the obligations assumed by [Marathon] herein, [Marathon’s] acts or omissions, [Oxy’s] acts or omissions with respect to the Properties, the ownership or operation of the Properties by [Oxy] or [Marathon] on or after the effective date, or which arise or are asserted with respect to the Properties on or after the effective date, or which are attributable to the ownership or operation of the Properties on or after the said effective date by [Oxy] or [Marathon] . . . .

C. Marathon’s July 2015 Sale to Legacy In July 2015, Marathon sold the Louisiana Assets to Legacy pursuant to a purchase-and-sale agreement (the Marathon–Legacy PSA). The Marathon–Legacy PSA contained the following provision regarding Legacy’s assumption of Marathon’s liabilities:

[Legacy] assumes and hereby agrees to fulfill, perform, pay, and discharge . . . all obligations and liabilities, known or unknown, with respect to the Assets, regardless of whether such obligations or liabilities arose prior to, on, or after the Effective Date, including obligations and liabilities relating in any manner to the Material Contracts or the condition, use, ownership, or operation of the Assets.
