RISK FACTORS

The following risk factors from the Offering Circular are amended to reflect the new offering price of $8.48 per Share:

The offering price was arbitrarily determined and is not the result of arm's-length negotiation.

The $8.48 per Share price was increased from the $7.77 per Share price set in Supplement No. 1 by our Board in its sole discretion after considering factors such as capital needs, comparable private-market transactions, and desired post-money ownership percentages. The price bears no direct relationship to book value, assets, earnings, or any established trading market. As a result, purchasers in this Offering could pay a price significantly higher than the intrinsic value of the Shares on the date of purchase.

Even if we complete a public offering, our Share price could be extremely volatile and decline significantly.

Newly listed development-stage energy companies often experience wide price swings due to limited float, small analyst coverage, and sensitivity to project milestones. If negative news-such as construction delays, cost overruns, or an offtake-contract termination-emerges shortly after listing, the market price could fall well below the IPO price and below the $8.48 per Share you pay in this Offering. Thin trading volume may exaggerate price moves, making it difficult to exit a position without materially affecting the market.

All other risk factors in the Offering Circular remain applicable. Investors should review "Risk Factors" beginning on page 9 of the Offering Circular.

PLAN OF DISTRIBUTION

The Company is currently offering up to 2,187,456 remaining Shares at $8.48 per Share, for up to a remaining $18,549,626.88 in proceeds from the sale of Shares and up to $556,488.81 in Investor Processing Fees. The minimum investment is $1,000.64 (118 Shares), or approximately $1,030.66 including the Investor Processing Fee.

Each investor will pay an Investor Processing Fee of 3% of the subscription amount (max $80 per transaction) to offset payment processing costs. The Broker receives 4.5% commission on this fee. The Company may waive this fee on a case-by-case basis.

Funds will be held in escrow until the Target Offering Amount is met. If not met by the Offering Deadline, all funds will be returned without interest. Closings occur promptly after receipt of funds, but no less than every 30 days.

Compensation, Fees and Expenses

The aggregate compensation payable to the Broker and its affiliates are updated sections of the "Plan of Distribution" on page 26 of the Offering Circular, as described below.

a.) Administrative and Compliance Related Functions

The Broker will provide administrative and compliance related functions in connection with this offering and for these services, we have agreed to pay Broker a cash commission equal to four and one-half percent (4.5%) of the amount raised for Share sales at the new price of $8.48, not to exceed $859,775.21, if remaining Shares are fully subscribed (including the maximum Investor Processing Fee total). This is in addition to the approximately $413,128 of commissions earned for 1,200,077 Share sales at prior prices.

c.) Marketing and Advisory Services

The Company has also engaged Reach, an affiliate of the Broker, for certain marketing advisory and consulting services, including some supplemental services on a case-by-case basis. For these ongoing services, we have agreed to pay Reach a one-time payment of $25,000, plus $8,000 per month up to $24,000, in advance of the Offering commencing for accountable expenses expected to be incurred. We have agreed to pay compensation of $8,000 monthly, up to $72,000, after the Offering commences. For supplemental marketing services we have agreed to compensation budget of up to $1,150,000 to be used on a case-by-case basis at the Company's discretion. For these services, we have agreed to pay Reach maximum compensation of $1,246,000.

The maximum compensation to be paid to Broker and affiliates is approximately $2,129,775.21 of the Offering proceeds, if fully subscribed at a price of $8.48 for the remaining Shares.

The offering terminates on the earliest of: (i) maximum offering amount sold; (ii) three years from initial qualification; or (iii) earlier termination by the Company.
