Explanation of Responses:

1. On November 30, 2018 (the "Closing Date"), MLN AcquisitionCo ULC (the "Purchaser") acquired all of the outstanding common shares of Mitel Networks Corporation (the "Issuer") under a plan of arrangement under the Canada Business Corporations Act (the "Plan of Arrangement"), and Issuer became a wholly owned subsidiary of the Purchaser, an entity currently owned and controlled by funds affiliated with Searchlight Capital Partners, L.P., a private equity investment group.

2. Pursuant to the Plan of Arrangement, each common share was transferred to the Purchaser in exchange for the right to receive US$11.15 in cash, without interest and less any applicable withholding taxes.

3. 5,100 common shares were held by the Spooner Children Trust, of which Mr. Spooner is one of three trustees, for the benefit of the children of Mr. Spooner. Mr. Spooner disclaimed beneficial ownership of the Common Shares held for the benefit of his children and this report shall not be deemed an admission that Mr. Spooner was a beneficial owner of such shares for purposes of Section 16 of the Securities Exchange Act of 1934, as amended, or for any other purpose.

4. Represents 99,000 options to purchase common shares (the "Options"), of which 86,625 were fully exercisable as of the Closing Date and the remaining 12,375 Options would have vested in equal installments every three months thereafter until March 4, 2020.
