Fortis Inc. ("Fortis" or the "Corporation") (TSX:FTS) announced today that it has entered into an agreement with a syndicate of underwriters led by Scotia Capital Inc. and RBC Dominion Securities Inc. pursuant to which they have agreed to purchase from Fortis and sell to the public 9,100,000 Common Shares of the Corporation. The underwriters will also have the option to purchase up to an additional 1,365,000 Common Shares to cover over-allotments, if any, and for market stabilization purposes, during the 30 days following the closing of the offering (the "Over-Allotment Option").

The purchase price of $33.00 per Common Share will result in gross proceeds to Fortis of $300,300,000 ($345,345,000, if the Over-Allotment Option is exercised in full). The net proceeds of the offering will be used (i) to repay indebtedness outstanding under the Corporation's committed credit facility, (ii) to finance additional equity injections into the Corporation's western Canadian regulated utilities and the non-regulated Waneta Expansion Limited Partnership in support of infrastructure investment, and (iii) for general corporate purposes.

The offering is subject to the receipt of all necessary regulatory and stock exchange approvals. Closing is expected to occur on or about June 15, 2011.
