**Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.**

Purchase Agreement. Under Section 8.9 and Section 8.10 of the Purchase Agreement, Westerman LP agreed that, without the prior written consent of the Issuer (as applicable), it will not transfer any equity consideration Common Units during the "Restricted Period," subject to enumerated "Permitted Transfers." The Restricted Period runs (i) for 50% of the equity consideration Common Units until six months after Closing and (ii) for the remaining 50% until twelve months after Closing. In addition, (A) Adjustment Common Units (as defined in the Purchase Agreement and with a value of $20,000,000) cease to be restricted following the final post closing purchase price adjustment and legend removal, and (B) Indemnification Reserve Common Units (as defined in the Purchase Agreement and with a value of $60,000,000)  are released from restrictions in tranches at twelve months and fifteen months after Closing, with any remaining reserve Common Units released upon final resolution of claims, in each case together with related legend removal mechanics. These restrictions are in addition to transfer restrictions under securities laws and any legends required by the Issuer's partnership agreement or the Purchase Agreement.

Registration Rights Agreement. Pursuant to the Registration Rights Agreement entered into on January 12, 2026, the Issuer has granted Westerman LP certain rights to require the Issuer to file and maintain the effectiveness of a registration statement with respect to the resale of the Common Units issued as the Unit Consideration (as defined in the Purchase Agreement), and under certain circumstances, to require the Issuer to initiate underwritten offerings for the Common Units to be issued as the Unit Consideration.

Board Observer Rights Agreement. Pursuant to the Board Observer Rights Agreement entered into on January 12, 2026, from the date of the Closing until the first anniversary thereof, Westerman LP is entitled to appoint one non-voting observer to the board of directors of the general partner of the Issuer (the "Board Observer"). In no event shall the Board Observer (i) be deemed to be a member of the board of directors of the Issuer, (ii) have or be deemed to have, or otherwise be subject to, any duties (fiduciary or otherwise) to the Issuer or its common unitholders, or (iii) have the right to vote on, or consent to, any matters presented to the board of directors of the Issuer or propose or offer any motions or resolutions to the board of directors of the Issuer. Westerman LP has designated Avril Westerman as its Board Observer.

The foregoing descriptions of the Purchase Agreement, the Registration Rights Agreement and the Board Observer Rights Agreement do not purport to be complete and are qualified in their entirety by reference to such agreements which are attached hereto as Exhibits 2, 3 and 4, respectively, and are incorporated herein by reference.

To the best knowledge of the Reporting Persons except as otherwise described in this Schedule 13D, there are no contracts, arrangements, understandings or relationships (legal or otherwise) between the Reporting Persons and any Governing Person or between the Reporting Persons, any Governing Person and any other person with respect to any securities of the Issuer, including any class of the Issuer's securities used as a reference security, in connection with any of the following: call options, put options, security-based swaps or any other derivative securities, transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
