The synergy of this proposed transaction is underscored by the shared nature of the core assets of the two companies. The Arrangement consolidates a 100% interest in the Roughrider uranium deposit and an approximate 98% interest in the large and prospective Russell Lake exploration project, located at either end, respectively, of the prolific eastern corridor of the Athabasca Basin.

Both companies believe this consolidation of property ownership will create value to a degree not possible for either company to achieve on its own; the sum is greater than the parts. Hathor shareholders are expected to realize full value for the mineral resource potential of the Roughrider deposit as it grows. Terra shareholders are expected to benefit more from full participation in Roughrider and in all of Hathor's other properties, including Russell Lake.

Hathor and Terra believe the combination of the two companies is a natural progression in the ongoing advancement of the Roughrider uranium deposit. This consolidation compliments and builds on the recent expansion and strengthening of Hathor's expert uranium exploration and management teams, the conversion of the Roughrider mineral claim to mineral lease, and the graduation of Hathor from the TSX Venture Exchange to a full listing on the Toronto Stock Exchange.

Each company is committed to a time is of the essence mandate in the execution of their business plans. Consolidating the fragmented ownership of Roughrider and Russell presents significant potential post-transaction value for both groups of shareholders.

Details of the Arrangement

The proposed transaction will be carried out by way of a plan of arrangement under the Business Corporation Act (British Columbia).

Under the Arrangement, Terra shareholders will receive 0.20 of a Hathor common share for each Terra common share held, resulting in Hathor issuing approximately 12.4 million of its common shares to Terra shareholders representing approximately 10% of Hathor's total post-Arrangement issued and outstanding share capital. All outstanding Terra options and warrants will be replaced or assumed by Hathor and exercisable to acquire Hathor shares with the number of Hathor shares and exercise price adjusted, as appropriate, to reflect the consideration to be received by the Terra shareholders pursuant to the Arrangement.

Based on Hathor's closing share price on April 15, 2011 (the last full trading day prior to the announcement of the Arrangement), the proposed exchange ratio represents a 16% premium to Terra's closing share price on April 15, 2011 and a 13% premium based on the 20-day volume weighted average share prices for the two companies' shares up to that date. The proposed Arrangement values Terra at approximately $24 million.

The implementation of the Arrangement will be subject to a number of conditions, including approval by at least 66 2/3% of the votes cast at a special meeting of Terra shareholders that is expected to be held in June, 2011, approval of the Supreme Court of British Columbia, approval of the Toronto Stock Exchange and the TSX Venture Exchange, completion of satisfactory due diligence on or before May 2, 2011, completion of definitive documentation and such other conditions as are customary for a transaction of this nature.

The Agreement also provides for, among other things, customary board support and non-solicitation covenants from Terra (subject to customary "fiduciary out" provisions that entitle Terra to consider and accept a superior proposal and a right in favour of Hathor to match any superior proposal). The Agreement also provides for the payment of a termination fee to Hathor of $625,000 should Terra accept an unsolicited superior proposal and terminate the Agreement.

The current management team of Hathor will manage the affairs of Terra upon completion of the Arrangement. The Board of Hathor has unanimously approved the Arrangement.

The Board of Directors of Terra has received an opinion from Cormark Securities Inc., its financial advisor, that as of the date of the Agreement, the consideration received pursuant to the Arrangement is fair, from a financial point of view, to Terra shareholders. The Board of Directors of Terra, with one dissenting member, is recommending that Terra shareholders vote in favour of the Arrangement.

Hathor is a publicly-traded mineral exploration company listed on the Toronto Stock Exchange trading under the symbol HAT. Hathor is focused on uranium exploration in the Athabasca Basin region of Saskatchewan and Alberta. The Athabasca Basin is the preeminent exploration district in the world for high grade uranium, and for the past 30 years has been responsible for between 20 and 30% of global annual uranium mine production. Hathor's Roughrider uranium deposit is within the northern part of the main uranium-producing eastern corridor of the Athabasca Basin. The property has been converted from mineral claim to mineral lease, and following the discovery in 2008, Hathor continues to drill, update and optimize the overall resource potential of three different mineral zones identified to date. Terra owns a 10% interest in the largest claim on the property containing the entire deposit known to date, carried to the completion of a positive feasibility study and announcement of intent for commercial production. Hathor's exploration pipeline behind Roughrider is highlighted by the 74,000 ha Russell Lake property located in the southern portion of the eastern corridor of the Basin. The property has numerous early stage targets in various stages of development and testing.
