LONDON, UK and CALGARY, AB / ACCESSWIRE / April 19, 2022 / Canadian Overseas Petroleum Limited ("COPL" or the "Company") (CSE:XOP)(LSE:COPL), an international oil and gas exploration, production and development company with production and development operations focused in Converse and Natrona Counties, Wyoming, USA, is pleased to announce that it successfully completed an oversubscribed accelerated bookbuild process.

The oversubscribed accelerated bookbuild process announced on April 19, 2022 has raised gross proceeds of USD13 million. A total of 49,930,000 units of the Company (the "Placing Units") were placed by H&P Advisory Limited ("Hannam & Partners") and Tennyson Securities (a trading name of Shard Capital Partners LLP) ("Tennyson Securities") (the "Bookrunners") with institutional investors at a price of 20 pence per Placing Unit. Each Placing Unit comprises one common share in the Company (each a "Common Share") and one half of one common share purchase warrant (each whole warrant, a "Warrant"). Each Warrant shall entitle the holder thereof to purchase one additional Common Share, exercisable at 24 pence per Common Share for the period of 6 months from the Settlement Date (as defined below) of the Placing Shares.

The 49,930,000 Common Shares comprised in the Units to be issued pursuant to the Placing (the "Placing Shares") will, when issued, be credited as fully paid and will rank pari passu in all respects with the existing issued Common Shares. Settlement of transactions in the Placing Shares is expected to take place, through depositary interests ("DIs") within the CREST system, on or around 22 April 2022 (the "Settlement Date").

The net proceeds of the Placing, in conjunction with COPL's other financial resources, are intended to be used for facility upgrades and drilling activities, and for general working capital.

Applications will be made to the FCA for the Placing Shares to be admitted to the Official List and to the London Stock Exchange for the Placing Shares to be admitted to trading on the London Stock Exchange's main market for listed securities within the next twelve months, in accordance with Listing Rule 14.3.4. Following the Placing, , the Company will have a total of 244,449,464 Common Shares issued and outstanding. There are no Common Shares held in treasury and therefore the total number of voting rights in the Company is 244,449,464. This figure may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the Financial Conduct Authority's Disclosure Guidance and Transparency Rules.

Arthur Millholland, President & CEO, commented:

"We remain fortunate to have a strong and supportive equity ownership base. We are taking this opportunity to ensure they can participate in our future expected success and fund the proposed expansionary capex that will be associated with our new and increased ownership in our flagship assets."

COPL is an international oil and gas exploration, development and production company actively pursuing opportunities in the United States with operations in Converse County Wyoming, and in sub-Saharan Africa through its ShoreCan joint venture company in Nigeria, and independently in other countries.
