Premier Gold has previously provided a bridge loan facility to Premier Royalty in connection with the acquisition by Premier Royalty of certain royalties. In addition to stipulated cash payback provisions, Premier Gold will be granted a one-time right in its sole discretion to convert all or a portion of the bridge loan into units of Bridgeport, each such unit consisting of one common share of Bridgeport and 0.375 of a Bridgeport Warrant. In addition, convertible securities of Premier Royalty granted to certain vendors of royalty interests will convert into common shares or warrants of Bridgeport in connection with the Transaction.

Premier Gold shall have the right to rename Bridgeport and set its new management team upon completion of the Transaction. Bridgeport shall be entitled to two seats on the resulting Board of Directors.

Premier Royalty is arranging a non-brokered financing (the “Financing”) of between $7 million and $10 million of convertible debentures which will accrue interest at a rate of 8% per annum. If the Transaction is completed, the convertible debentures will convert into Bridgeport units. Each unit will consist of one common share of Bridgeport and 0.375 of a Bridgeport warrant, which warrants will have the same terms as the Bridgeport Warrants discussed above. The proceeds will be used for royalty acquisitions and working capital. It is anticipated that the Financing will be completed prior to the signing of the Definitive Agreement.

Bridgeport President and CEO, Shastri Ramnath said, “The acquisition of Premier Royalty by Bridgeport will expose Bridgeport shareholders to a well-managed corporation with a diversified portfolio of gold royalty assets, many of which are in production and operated by senior gold producers and will form the core of a business with excellent growth potential, particularly in the current economic climate.”

Abraham Drost, Chairman of Premier Royalty Corporation stated: “Premier Royalty’s planned merger with Bridgeport forms our awaited go-public event as a TSX company. The move will provide additional cash resources for new royalty acquisitions and a strong shareholder base which will help advance the company’s growth plans significantly.”

The Transaction is subject to, among other things, the negotiation and execution of a definitive binding agreement (the “Definitive Agreement”), approval of the board of directors of each of Premier Gold and Bridgeport, approval of Bridgeport’s shareholders, regulatory approvals, completion of due diligence and the entering into of support and lock-up agreements by Bridgeport’s directors and officers. Premier Gold and Bridgeport have agreed to deal exclusively with each other until July 31, 2012. It is anticipated that the Definitive Agreement will be executed on or about July 11, 2012. Further details will be announced upon the entering into of the Definitive Agreement. CIBC World Markets Inc. is acting as financial advisor to Premier Gold and Premier Royalty in connection with the Transaction and PowerOne Capital Markets Limited is acting as financial advisor to Bridgeport in connection with the Transaction.
