Net Present Value of Future Net Revenue of Gas Reserves

Notes:

1. During the third quarter of 2015, The Petroleum Act, 2015 (the "Act") was passed into law by Presidential decree. The Act repeals earlier legislation, provides a regulatory framework over upstream, mid-stream and downstream gas activity, and as well consolidates and puts in place a single, effective and comprehensive legal framework for regulating the oil and gas industry in Tanzania. The Act also provides for the creation of an upstream regulator, the Petroleum Upstream Regulatory Authority. The mid and downstream petroleum as well as gas activities are proposed to be regulated by the current authority, the Energy and Water Utilities Regulatory Authority ("EWURA"). The Act also confers upon on the TPDC the status of the National Oil Company, mandated with the task of managing the country’s commercial interest in the petroleum operations as well as mid and downstream natural gas activities. The Act vests TPDC with exclusive rights in the entire petroleum upstream value chain and the natural gas mid and downstream value chain. However, the exclusive rights of TPDC do not extend to mid and downstream petroleum supply operations. The Act does provide grandfathering provisions upholding the rights of the Company under the Songo Songo PSA as it was signed prior to the passing of the Act.

2. On October 7, 2016, the Government of Tanzania issued the Petroleum (Natural Gas Pricing) Regulation made under Sections 165 and 258 (1) of the Act (the "Natural Gas Pricing Policy"). Article 260(3) of the Act preserves the Company's pre-existing right with TPDC to market and sell natural gas together or independently on terms and conditions (including prices) negotiated with third party natural gas customers. To date, the Natural Gas Pricing Policy has not impacted the Company's ability to market and sell natural gas at prices freely negotiated with natural gas customers. The future impact of the Natural Gas Pricing Policy, if any, cannot be determined at this time.

3. On January 16, 2018, Orca sold (the "First Swala Transaction") 7.933 percent of the Class A common shares (7,933 Class A common shares) of its wholly owned subsidiary PAE PanAfrican Energy Corporation ("PAEM"), a Mauritius registered Company and sole shareholder of PAET, a Jersey registered Company, to a wholly owned subsidiary of Swala. The Songo Songo PSA is held by PAET. While Swala had no management or control of PAEM and no shareholding in, or management or control of PAET, the McDaniel Report was previously prepared based on Orca’s ownership of 92.07 percent of PAET's gross reserves. On July 21, 2023, the Company repurchased (the “Second Swala Transaction”) the 7.933% shares in PAEM eliminating Swala’s interest in the reserves. Accordingly, the 2024 McDaniel Report is prepared based on Orca’s ownership of 100% of PAET’s gross reserves.

4. "Company Gross Reserves" are the total of the Company’s working interest share in reserves before deduction of royalties owned by others and without including any royalty interests of the Company.

5. "Company Net Reserves" are the total of the Company’s working interest share in reserves after deducting the amounts attributable to royalties and Profit Gas owned by others (as defined in the PSA), plus the Company's royalty interests in such reserves.

6. Company Gross and Net Reserves are based on the Company’s 100 percent ownership interest in the reserves following the Second Swala Transaction.

7. Under the terms of the Songo Songo Production Sharing Agreement with TPDC and the Government of Tanzania ("PSA"), the Company is required to pay Tanzanian income tax, but this is recovered by the Company through the profit sharing arrangements with TPDC. Where income tax is accrued, the Company's revenue will be grossed up by the tax due and the tax will be shown as a tax in the Company's accounts. However, the income tax has no material impact on the cash flows emanating from the PSA and accordingly it has not been identified as a separate cash flow stream in the analysis of the net present values.

McDaniel employed the following gas sales, pricing and inflation rate assumptions as of December 31, 2024 in estimating the Company's reserves data using forecast prices and costs. The Company received an average gas price of $4.67/Mcf in 2024 and $4.22/Mcf net of the transportation tariff imposed by Songas Limited as determined by the energy regulator, EWURA.

Note:   Brent price forecast based on the McDaniel January 1, 2025 price forecast.

The price of gas for the Industrial sector is based on a formula related to discounts to heavy fuel oil prices and includes caps and floors. This has been reflected in the above pricing.
