              Moody's Upgrades Mitel's Corporate Rating to "B2"

             Standard & Poor's Maintains Corporate Rating at "B"

OTTAWA, Jan. 10, 2014 (GLOBE NEWSWIRE) -- Mitel® (Nasdaq:MITL) (TSX:MNW), a
leading provider of cloud and software-based unified communications and
collaboration (UCC) solutions, today announced that Moody's and Standard &
Poor's have published their respective ratings of the company's proposed
US$355 million term loan. The debt is being issued in conjunction with the
company's previously announced acquisition of Aastra Technologies and to
refinance existing debt issued by Mitel.

Moody's assigned a "Ba3" rating to the new term debt and upgraded Mitel's
corporate family rating, or CFR, to "B2" from "B3" with a "stable" outlook.

Standard & Poor's issued a "B+" rating to the new credit, assigning it a
Recovery Rating of "2". The agency corporate rating of "B" on Mitel with a
"positive" ratings outlook is unchanged.

Steve Spooner, Chief Financial Officer of Mitel, commented, "We view the
ratings issued for our proposed new credit facility as a strong endorsement of
the decision to combine Mitel and Aastra to become one of our industry's
leading companies. Our ability to integrate quickly and generate the $50
million in synergies we have outlined will enable us to further strengthen the
balance sheet of the billion dollar company this merger creates."
