Equal Energy Says Oklahoma Tornado Will Not Have Material Impact On

Company; Announces Investor and Analyst Field Trip

OKLAHOMA CITY, June 3, 2013 /CNW/—Equal Energy Ltd. (NYSE:EQU) (TSX:EQU.TO) today reported the effect on its operations of a tornado that occurred on Sunday, May 19, 2013. Specifically, Equal announced that its two field office buildings in Carney, Oklahoma were largely destroyed and that production was temporarily reduced. However,none of the company’s employees or their families were injured. The company does not expect a material impact on its financial results.

Separately, Equal said it has posted to its website (www.equalenergy.ca) the presentation from its recent Annual and Special Meeting of shareholders. Equal also announced that despite the tornado damage it intends to host a site visit at its Oklahoma facilities on June 25, 2013, for investors and analysts. Interested parties should notify Equal at info@equalenergy.ca or 405-242-6000 by June 10, 2013.

With regard to the May 19th tornado, Equal said five of its Carney-based employees who live in the community survived by sheltering in a safe room at one of Equal’s two Carney buildings. Those employees also invited 19 family members and neighbors into the safe room, all of whom were uninjured. Equal extends its sympathy and support to those who suffered more severely from this tornado and others that touched down in Oklahoma and nearby states in mid-May.

“I’m very proud of the response by all of our Oklahoma employees, whose top priority was safety,” said Don Klapko, President and Chief Executive Officer. “After the tornado passed they moved quickly to determine each others’ whereabouts and well-being. They then assessed the extent of the damage to the producing assets and took steps to minimize any disruption to production. Within 48 hours of the storm they re-established a temporary field office using portable offices, they salvaged files and other materials from the damaged buildings, and they recovered and repaired field vehicles and other key assets. Thanks to their efforts, we are well positioned to carry on.”

Equal expects that damage from the tornado will largely be covered by insurance. The determination of rebuilding costs remains subject to a number of factors, including an inspection by a structural engineer to determine if one of the two buildings may be partly salvageable and consultation with an architect. Based on preliminary information, Equal expects that it may be able to move back into permanent structures at Carney by the end of 2013 or early in 2014.

Equal estimates that tornado-related disruptions reduced May production by less than 100 barrels of oil equivalent per day (boe/d). Production was back to normal three days after the tornado and Equal remains on track to achieve its 2013 guidance of an average of 6,400 boe/d.
