Fortis and UNS Energy File Settlement Agreement

ST. JOHN'S, NEWFOUNDLAND AND LABRADOR--(Marketwired - May 16, 2014) - As previously reported on January 10, 2014, Fortis Inc. ("Fortis") (TSX:FTS) and UNS Energy Corporation ("UNS Energy") (NYSE:UNS) filed an application with the Arizona Corporation Commission ("ACC") requesting that the ACC approve a proposed merger ("Merger") in which UNS Energy would become an indirect wholly owned subsidiary of Fortis.

Completion of the Merger is subject to the following remaining processes: the approval of the ACC; the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; the review of the Merger by the Committee on Foreign Investment in the United States; and the satisfaction of other customary closing conditions.

On May 16, 2014, UNS Energy, Fortis, ACC Staff, the Residential Utility Consumer Office and other parties to the Merger proceedings entered into a settlement ("Settlement") in which the parties agree that the Merger is in the public interest, and recommend approval by the ACC, subject to certain conditions. Those conditions include, but are not limited to, the following:

• UNS Energy shall provide benefits totaling US$30 million over five years to the retail customers of its utility subsidiaries Tucson Electric Power Company, UNS Electric, Inc. and UNS Gas, Inc. (collectively, the "Regulated Utilities"); US$10 million in year one, and US$5 million annually in years two through five. The amounts will be credited to customers' bills.

• UNS Energy and the Regulated Utilities will adopt certain ring-fencing and corporate governance provisions.

• Dividends paid from the Regulated Utilities to UNS Energy cannot exceed 60 percent of the Regulated Utilities' respective net income for a period of five years or until such time that their respective equity capitalization reaches 50 percent of total capital (excluding any goodwill recorded) as accounted for in accordance with U.S. Generally Accepted Accounting Principles. The dividend restrictions are contingent upon receiving necessary consents of the lenders in UNS Energy's credit facility.

• Fortis shall make an equity infusion totalling US$220 million through UNS Energy into the Regulated Utilities following closing of the Merger. However, if the Merger closes after September 30, 2014, the equity infusion may be made into UNS Energy to retire debt.

The Settlement is subject to the review and approval of the ACC, which could approve, reject or require modifications to the Settlement as a condition of approval. ACC approval of the Merger must be obtained before the Merger can be completed.
