REGEN TRADEMARK ACCEPTED IN THE UNITED STATES

In addition to trademarks previously awarded in Canada, the European Union, the United Kingdom, Malaysia, Singapore, Mexico and India, a Certificate of Registration was issued on October 10, 2023 by the USPTO for the 'ReGen' mark. In the United States, a trademark is granted for an initial period of ten years, after which it may be renewed for consecutive ten-year periods.

U.S. DEPARTMENT OF ENERGY LOAN PROGRAMS OFFICE APPLICATION

ReGen III continues to meet and engage with representatives of the U.S. Department of Energy's Loan Programs Office ("LPO") to incorporate feedback regarding the Company's draft application. The Company recently submitted additional revisions and materials as part of the pre-application process, in advance of finalizing its formal application.

CONVERTIBLE DEBENTURE FINANCING

The Company has closed the second and final tranche (the "Second Tranche") of its non-brokered private placement (the "Placement") announced October 30, 2023, issuing 645 Convertible Debenture Units (the "Units") at a price of $1,000 per Unit for aggregate gross proceeds of $645,000. This brings the combined gross proceeds raised from the November 20 tranche and the Second Tranche to $3,000,000.

Each Unit consists of $1,000 in principal amount of unsecured convertible debenture (a "Debenture") and 1,000 common share purchase warrants (a "Warrant"), with each Warrant exercisable to purchase one common share at a price of $0.55 for a period of 24 months after closing.

The Debentures have a term of 24 months and will accrue interest at a rate of 14% per annum, payable in arrears on a semi-annual basis, and on maturity. After 12 months, the Company may, subject to the prior approval of the TSX Venture Exchange (the "Exchange"), elect to pay outstanding interest in common shares ("Interest Shares") at a price per share equal to the greater of (i) the volume weighted average price of the common shares on the Exchange for the 5 trading days prior to the date such interest is due, and (ii) the Discounted Market Price (as defined by the Exchange) at that time.

The Debentures will be convertible at the option of the holder into common shares at a price of $0.55 per common share. After 4 months, the Company may redeem the Debentures in whole or in part by payment of 115% of the principal amount being redeemed, in cash, together with payment of any accrued but unpaid interest on the principal amount being redeemed, in cash or Interest Shares or a combination thereof.

The Debentures and Warrants issued in the Second Tranche and any underlying common shares are subject to a hold period expiring on April 21, 2024. In connection with the Second Tranche, the Company paid finder fees of $30,000 in cash. The Company intends to use the net proceeds from the Placement to advance the Company's re-refinery engineering, including consulting studies, for general working capital, and to evaluate potential mergers and acquisitions.

Including the initial tranche, the Directors and executive officers of the Company acquired ownership or control over an aggregate of 145 Units, representing approximately 4.83% of the total number of Debentures and Warrants issued in the Placement, and which if immediately converted and exercised respectively as of the closing of the Second Tranche would result in the issue of 408,636 common shares representing approximately 0.34% of the then issued and outstanding common shares. The participation by insiders constitutes a "related party transaction" within the meaning of Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The Company has relied upon the exemption from the formal valuation and minority shareholder approval requirements pursuant to sections 5.5(a), (b) and (c), and sections 5.7(1)(a) and (b), respectively, of MI 61-101.
