Re: Loan No. 9000083212 Tetra4 Helium Project – Request for Consent to Mahlako Subscription, Restricted Payment and Waiver of Restricted Payment Conditions

Ladies and Gentlemen,

Introduction

1.1

We refer to the Finance Agreement dated August 20, 2019 between Tetra4 Proprietary Limited (the “Borrower”) and the United States International Development Finance Corporation, an agency of the United States of America (“DFC”) (the “Finance Agreement).

1.2

Unless otherwise expressly defined in this letter, capitalized terms in this letter shall have the meanings given to them in the Finance Agreement.

Background

2.1

Renergen Limited (“Renergen,” and together with the Borrower, collectively the “Borrower Parties”) entered into a Bridge Loan Facility Agreement (the “Bridge Loan Agreement”) with Standard Bank of South Africa (acting through its Corporate and Investment Banking Division) (“SBSA”) on or about June 29, 2023, pursuant to which SBSA made a ZAR 303 million bridge loan (the “Bridge Loan”) to Renergen for the purpose of providing short-term bridge funding for the Borrower’s operations in anticipation of the Borrower raising equity capital by way of a new share issue.

2.2

The Borrower is in the process of negotiating the subscription by Mahlako Gas Energy Proprietary Limited (“Mahlako”) for new ordinary shares representing up to 10% of the Borrower’s share capital (the “Mahlako Subscription”). Upon successful completion of the Mahlako Subscription, the Borrower intends to distribute to Renergen a portion of the Mahlako Subscription proceeds in an amount not to exceed the amount sufficient to enable Renergen to prepay the Bridge Loan in full (the “Bridge Loan Distribution”);

2.3

Renergen will apply the proceeds of the Bridge Loan Distribution solely to prepay the Bridge Loan in full.

2.4

Each Borrower Party agrees and acknowledges that each of the (i) Mahlako Subscription and (ii) the Bridge Loan Distribution require DFC’s consent under the Finance Agreement.

2.5

The Borrower undertakes to achieve Project Completion no later than February 15, 2024 (the “Project Completion Longstop Date”) and requests that the Lender consent to such date (the “Project Completion Date Extension”).

4.3

The Borrower undertakes to maintain compliance with the financial ratios included in paragraphs (a) and (b) of Section 6.10 (Financial Ratios; DSR Requirement) of the Finance Agreement at all times immediately following August 15, 2025.
