Cardinal Energy Group Inc. (OTC: CEGX) sold $3.5 million of 12% senior secured convertible notes to investors, the company said April 22.

The notes will mature Dec. 31, 2015, the company said, noting that an additional $1.5 million of notes was placed with investors, making the total amount $5 million.

The additional notes were issued under the same terms, Cardinal Energy said, noting that all proceeds will go toward reworking and recompleting Cardinal Energy’s 78 Texas wells. Proceeds will also fund strategic acquisitions and working capital, and they will be paid in cash, the company added.

The notes’ conversion price is $1 per share, the company said.

CEO Timothy Crawford said, "We are encouraged with the strong investor interest we received for our convertible preferred offering. With rising production and a number of new wells expected to come online throughout 2014, we expect to generate attractive returns with this additional capital."

Syndicated Capital was the sole placement agent for the sale, the company said.

Dublin, Ohio-based Cardinal Energy Group Inc. produces dry gas in California and oil in Texas.
