PROSTAR ANNOUNCES OHIO CUMBERLAND GAS COMPANY ADOPTS POINTMAN TO ENHANCE THEIR GAS LINE OPERATIONS

Ohio Cumberland Gas Company has adopted Prostar Holdings Inc.'s precision mapping technology, PointMan, to enhance the management of its gas service and distribution lines.

"Knowing the location of our assets is critical to the success of our operations and servicing our customers," stated Austin Stritmatter, vice-president of Ohio Cumberland Gas Co. "We believe PointMan will be an ideal solution to help transition us from paper maps, which have serious limitations, to precise digital mapping records of our entire utility infrastructure."

Established in 1906, Ohio Cumberland is a privately owned natural gas public utility. Ohio Cumberland currently has over 300 miles of gathering and distribution lines servicing parts of Knox, Ashland, Coshocton, Holmes, Licking, Morrow and Richland counties. They serve about 2,400 residential, commercial and industrial customers. As a public utility, Ohio Cumberland is subject to the supervision and jurisdiction of the Public Utilities Commission of Ohio and the United States Department of Transportation.

"PointMan is specifically designed to help transition companies like Ohio Cumberland Gas away from paper maps to a cloud and mobile digital mapping solution, which aims to improve operations and address safety and environmental concerns," stated Page Tucker, chief executive officer of Prostar.

The company is also pleased to announce that it has engaged Independent Trading Group (ITG) Inc., an arm's-length party to the company, to provide market making services with the objective of maintaining a reasonable market and improving the liquidity of the company's securities.

Under the agreement dated April 1, 2023, ITG will trade the common shares of Prostar on the TSX Venture Exchange. The engagement has an initial term of three months and will renew for subsequent one-month terms, unless either party provides 30 days written notice prior to the end of a term. The company will pay ITG a $5,000 fee plus applicable taxes on the first business day of each month, for as long as the agreement is in force. At the time the parties entered into the agreement ITG did not own any securities of the company; however, ITG has since acquired a direct interest in the securities of the company. There are no performance factors contained in the agreement between ITG and the company and ITG will not receive any shares or options from the company as compensation for services it will render. The capital used for market making will be provided by ITG and will be done in accordance with TSX Venture Exchange policies and securities laws. The agreement is subject to acceptance for filing by the TSX Venture Exchange.

Finally, the company announces it has agreed to issue an aggregate of 241,006 common shares of the company at a price of 34 cents per share in settlement of payment owed pursuant to a production and broadcasting agreement with New to the Street Group LLC, totalling $60,000 (U.S.) ($81,942).

The debt settlement is subject to TSX-V approval. The settlement shares will be subject to a statutory hold period of four months from the date of issuance, in accordance with applicable securities legislation.
