RECITALS

** **

WHEREAS, Abstract is the holder of shares of RITE Series NMC $25 Convertible Preferred Stock (“Series NMC Preferred”);

** **

**WHEREAS, **RITE desires to repurchase 3,919,388 shares of Series NMC Preferred from Abstract at approximately $27.23 per share, for an aggregate repurchase price of $106,724,942.00, which RITE will satisfy by issuance of a promissory note to Abstract, and Abstract desires to sell such shares to RITE on the terms stated herein;

** **

**WHEREAS, **as part of the same integrated transaction, Abstract intends to apply all of that Note to reacquire the royalty asset held by RITE that was originally transferred by Abstract, to fund on behalf of Commodity Capital Advisors LLC the reacquisition by Commodity Capital Advisors LLC of its royalty asset, to exercise all Series D and Series NMC warrants held by Abstract, and to fund and effect the exercise, on behalf of Commodity Capital Advisors LLC, of the Series D warrants held by Commodity Capital Advisors LLC; and

** **

WHEREAS, the Parties also desire to establish a permanent cap on the total amount payable under the sinking-fund applicable to all Series NMC Preferred now or hereafter held by Abstract, including Series NMC Preferred issued to Abstract upon exercise of Series NMC warrants.

** **

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Parties agree as follows:

** **

1. REPURCHASE OF SERIES NMC PREFERRED

1.1 Repurchase. Abstract hereby sells, assigns, transfers and surrenders to RITE, and RITE hereby repurchases from Abstract, 3,919,388 shares of Series NMC Preferred (the “Repurchased Shares”) at approximately $27.23 per share, for an aggregate repurchase price of $106,724,942.00 (the “Repurchase Price”).

1.2 Status of Repurchased Shares. Effective upon Closing, the Repurchased Shares shall cease to be outstanding and shall have no further voting, conversion, sinking-fund, distribution or other rights. RITE shall cause the Repurchased Shares to be reflected on its books and transfer-agent records in accordance with RITE’s governing documents and applicable law.

1.3 Title. Abstract represents that it owns the Repurchased Shares, has authority to transfer them, and has not created any lien, pledge or security interest upon them.

** **

2. PAYMENT BY PROMISSORY NOTE

** **

At Closing, RITE shall issue to Abstract a non-interest-bearing promissory note in the original principal amount of $106,724,942.00 (the “Note”), substantially in the form executed contemporaneously herewith. The Note may be paid and satisfied by contractual setoff and application against amounts payable by Abstract to RITE, including royalty repurchase prices and warrant exercise prices.

** **

3. SINKING-FUND AMOUNT AND PERMANENT CAP

3.1 Calculation. As between RITE and Abstract, the Parties agree that the five percent (5%) per annum growth of the Series NMC sinking-fund repurchase price has been calculated on a compounding basis, such that the repurchase price at the start of each annual period is increased by five percent (5%) for that period, beginning from the original $25.00 per-share base, subject to the existing $25.40 floor, with proportionate accrual for partial years. The Parties confirm that, as of September 30, 2026, the Series NMC sinking-fund repurchase price is approximately $27.23 per share.

3.2 Covered Shares. This Section applies to every share of Series NMC Preferred now or hereafter owned by Abstract, including the Series NMC Preferred remaining after the Repurchase and all Series NMC Preferred issued to Abstract upon exercise of Series NMC warrants (collectively, the “Covered NMC Shares”).

3.3 Permanent Cap. Notwithstanding anything to the contrary in any prior agreement, instrument, designation, sinking-fund provision or other arrangement applicable to the Covered NMC Shares, the aggregate amount payable by RITE under the sinking fund with respect to all Covered NMC Shares shall in no event exceed $269,049,058.76 (the “Aggregate Cap”). Upon the aggregate sinking-fund value of the Covered NMC Shares reaching the Aggregate Cap, all further accretion with respect to the Covered NMC Shares shall permanently cease.

3.4 Application of Sinking Fund Cap. Following completion of the transactions contemplated by this Agreement and the contemporaneous exercise of the Series NMC warrants, the Parties expect Abstract to hold an aggregate of 9,880,612 shares of Series NMC Preferred Stock. Such amount reflects (i) Abstract’s existing 6,900,000 Series NMC Preferred shares, less the 3,919,388 Series NMC Preferred shares being repurchased by RITE pursuant to this Agreement, leaving 2,980,612 Series NMC Preferred shares, plus (ii) 6,900,000 additional Series NMC Preferred shares to be issued to Abstract upon the contemporaneous exercise of all 6,900,000 Series NMC warrants.

Based upon 9,880,612 Covered NMC Shares, the $269,049,058.76 Aggregate Cap is equivalent to approximately $27.2300 per share. This per-share amount is provided solely for illustrative purposes and shall not constitute a separate or independent cap, floor, guaranteed repurchase price or other limitation. The $269,049,058.76 Aggregate Cap shall control in all cases, regardless of the number of Covered NMC Shares outstanding or held by Abstract or any permitted transferee.

Upon the aggregate sinking-fund value of the Covered NMC Shares reaching $269,049,058.76, the sinking-fund value shall cease to increase, no further accretion shall accrue or be added thereafter, and RITE’s aggregate sinking-fund obligation with respect to all Covered NMC Shares shall not exceed $269,049,058.76.

3.5 Transfers of Covered NMC Shares. Abstract may transfer any of the Covered NMC Shares, provided that any transferee agrees in writing to be bound by the sinking-fund terms and limitations set forth in this Section 3 with respect to the shares transferred. The purpose of this provision is to ensure that a transfer of Covered NMC Shares does not increase, avoid, or otherwise alter the sinking-fund limitations agreed to by RITE and Abstract under this Agreement. Any Covered NMC Shares transferred by Abstract shall therefore remain subject to the same sinking-fund terms and limitations that applied to those shares immediately prior to the transfer.

** **

4. CLOSING; INTEGRATED TRANSACTION

** **

The Repurchase, issuance of the Note, royalty repurchases, warrant exercises, application and satisfaction of the Note, and related issuances are intended to occur as components of one integrated and substantially simultaneous Closing. Each Party shall execute such stock powers, exercise notices, transfer-agent instructions and other ministerial documents reasonably necessary to carry out the transaction.
