Algonquin Oil & Gas Completes Business Combination With Mondak Petroleum

CHATHAM, ONTARIO--(Marketwire - March 12, 2012) -

NOT FOR DISTRIBUTION TO UNITED STATES NEWS WIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.

Algonquin Oil & Gas Limited (TSX VENTURE:AQX) ("Algonquin") is pleased to announce that it has completed its previously announced arm's length business combination with Mondak Petroleum Inc. ("Mondak"), a private oil and gas company.

Financing

Immediately prior to the completion of the business combination, Mondak completed its previously announced brokered private placement (the "Private Placement") of units ("Units"). Mondak issued an aggregate of 193,500,000 Units at a price of $0.15 per Unit for gross proceeds of $29,025,000. Each Unit was comprised of one Class A common voting share in the capital of Mondak (each, a "Mondak Voting Share") and one-half of one common voting share purchase warrant (each, "Mondak Class A Warrant"). Each whole Mondak Class A Warrant entitles the holder to acquire one Mondak Voting Share at a price of $0.25 per share for a period of 18 months from the date of issuance of such warrants. The Private Placement was completed through a syndicate of agents led by Macquarie Capital Markets Canada Ltd. and including Canaccord Genuity Corp., GMP Securities L.P., AltaCorp Capital Inc. and Raymond James Ltd. (collectively, the "Agents"). In consideration for their services under the Private Placement, the Agents received an aggregate fee equal to 6% of the gross proceeds raised under the Private Placement.

M. Bruce Chernoff and/or associates, affiliates or entities in close association with Mr. Chernoff ("Chernoff") acquired 110,666,667 Units under the Private Placement. After giving effect to the Private Placement and the Arrangement (described below), it was expected that Chernoff would own or exert control or direction over approximately 49.9% of the then outstanding Algonquin common voting shares ("Algonquin Voting Shares") and would be considered a new control person of Algonquin. As a result, prior to completing the Private Placement, Algonquin obtained the written approval of disinterested shareholders holding approximately 66% of the current issued and outstanding Algonquin Voting Shares to the creation of Chernoff as a new control person upon completion of the Arrangement.

Option Agreement

Mondak and its wholly-owned United States subsidiary, Mondak Petroleum (US), Inc. ("Mondak Sub"), used the net proceeds of the Private Placement, in part, to fund the exercise of Mondak Sub's option to acquire a 10% non-operated working interest in certain leases held by Alameda Energy, Inc. ("Alameda"), an affiliate of Slawson Exploration Company, Inc. ("Slawson"), on approximately 37,300 acres located in Richland County, Montana and McKenzie County, North Dakota (the "Mondak Leases"). The purchase price paid by Mondak Sub for its working interest in the Mondak Leases was US$14,919,651. Mondak Sub also intends to use the net proceeds of the Private Placement to commence a drilling program on the Mondak Leases and for general corporate purposes.

As a result of exercising its option on the Mondak Leases, Mondak Sub now has an option (the "False Bakken Option") for a period of nine months to acquire a 10% non-operated working interest in approximately 80,000 acres located in the Dawson, Wibaux and Richland Counties of Montana (the "False Bakken Leases"). The purchase price to be paid by Mondak to exercise the False Bakken Option shall be US$2,000 per net mineral acre (or an aggregate of approximately US$15,000,000).

Alameda has retained the majority of the working interests in the Mondak Leases and is expected to retain the majority of the working interests in the False Bakken Leases if the False Bakken Option is exercised and Slawson will be the operator of these interests. Slawson is a privately held oil and gas exploration company which has drilled over 3,500 wells in various locations throughout the United States, including the Williston Basin, the Anadarko Basin, the Gulf Coast, the Kansas Basin and the Sacramento Basin. It is currently the 7th largest private oil producer in the United States and is the leading private oil producer in the Williston Bakken. Slawson has over 35 years of experience in the Williston Basin and has grown oil production, primarily through the drill bit, from less than 1,000 barrels per day to current operated production of over 25,000 barrels per day.

The Business Combination

After completing the Private Placement and exercising the option on the Mondak Leases, the business combination of Algonquin and Mondak was completed by way of a plan of arrangement (the "Arrangement") as set forth in an arrangement agreement dated November 12, 2011, as amended on December 13, 2011 and February 24, 2012 (collectively, the "Arrangement Agreement"). The Arrangement Agreement and the amendments thereto are available for review under Algonquin's profile on SEDAR (www.sedar.com) and the material terms of the Arrangement Agreement were summarized in Algonquin's Information Circular dated December 22, 2011 (also available for review under Algonquin's profile on SEDAR). The Arrangement Agreement provided for the following:

• a wholly-owned subsidiary of Algonquin ("Algonquin Sub") amalgamated (the "Amalgamation") with Mondak to form a new amalgamated entity ("Amalco") that continues under the name "Mondak Petroleum Inc.";
• Algonquin received shares of Amalco on the basis of one common share in the capital of Amalco for every common share of Algonquin Sub held immediately prior to the Amalgamation, resulting in Amalco becoming a wholly-owned subsidiary of Algonquin;
• the holders of the issued and outstanding Mondak Voting Shares received Algonquin Voting Shares on a one-for-one basis;
• the holders of the issued and outstanding Class B common non-voting shares in the capital of Mondak received common non-voting shares of Algonquin (each, an "Algonquin Non-Voting Share") on a one-for-one basis;
• the holders of Mondak Class A Warrants received common voting share purchase warrants of Algonquin on a one-for-one basis entitling such holders to acquire Algonquin Voting Shares on the same terms and conditions provided for by the Mondak Class A Warrants; and
• the holders of common non-voting share purchase warrants of Mondak (each, a "Mondak Class B Warrant") received common non-voting share purchase warrants of Algonquin on a one-for-one basis entitling such holders to acquire Algonquin Non-Voting Shares on the same terms and conditions provided for by the Mondak Class B Warrants.

PetroShale Inc.

In addition to the above, concurrent with the completion of the Arrangement, Algonquin changed its name to "PetroShale Inc." and immediately consolidated all of its issued and outstanding securities on a "1 new for 10 old" basis (the "Consolidation"). After giving effect to the Arrangement and the Consolidation, the issued and outstanding capital structure of PetroShale now consists of the following:

• 22,173,574 common voting shares of PetroShale ("PetroShale Voting Shares");
• 9,674,996 common voting purchase warrants, each such warrant entitling the holder to acquire a PetroShale Voting Share at a price of $2.50 per share until September 8, 2013;
• 6,700,000 common non-voting shares of PetroShale ("PetroShale Non-Voting Shares"); and
• 6,000,000 common non-voting purchase warrants, each such warrant entitling the holder to acquire a PetroShale Non-Voting Share at a price of $2.50 per share until September 8, 2013.
