(1) The reporting person may be deemed to have an indirect pecuniary interest as the General Partner of TA IX L.P. The reporting person disclaims benefical ownership of such shares because the reporting person's indirect pecuniary interest is subject to indeterminable future events.
(2) The shares of Series D Convertible Preferred Stock (the "Series D Preferred Stock") converted, along with any accrued but unpaid dividends thereon, into common stock of MetroPCS Communications, Inc. (the "Company"). Each share of Series D Preferred Stock represented an original investment of $100 which, with the accrued but unpaid dividends thereon, was converted to the Company's common stock at the rate of approximately $3.13 per share of common stock.
(3) The shares of Series E Convertible Preferred Stock (the "Series E Preferred Stock") converted, along with any accrued but unpaid dividends thereon, into common stock of MetroPCS Communications, Inc. (the "Company"). Each share of Series E Preferred Stock represented an original investment of $100 which, with the accrued but unpaid dividends thereon, was converted to the Company's common stock at the rate of $9.00 per share of common stock.
(4) The Series D Preferred Stock had been automatically convertible upon (i) completion of a Qualified Public Offering (as defined in the Securities Purchase Agreement, as amended); (ii) the Common Stock trading on a national securities exchange for a period of 30 consecutive trading dates above a price that implies a market valuation of the Series D Preferred Stock in excess of twice the initial purchase price of the Series D Preferred Stock; or (iii) the date specified by the holders of two-thirds of the initial purchase price of the Series D Preferred Stock. If not previously converted, the Company was required to redeem all outstanding shares of Series D Preferred Stock on July 17, 2015, at the liquidation value plus accrued but unpaid dividends.
(5) The Series E Preferred Stock had been automatically convertible upon (i) completion of a Qualified Public Offering (as defined in the Securities Purchase Agreement, as amended); (ii) the Common Stock trading on a national securities exchange for a period of 30 consecutive trading dates above a price that implies a market valuation of the Series E Preferred Stock in excess of twice the initial purchase price of the Series E Preferred Stock; or (iii) the date specified by the holders of two-thirds of the initial purchase price of the Series E Preferred Stock. If not previously converted, the Company was required to redeem all outstanding shares of Series E Preferred Stock on July 17, 2015, at the liquidation value plus accrued but unpaid dividends.
