Pursuant to the terms of the PSU Grants, 50% of the total shares remaining under the PSUs accelerated immediately upon the closing of the Mergers (as defined in Footnote 4 to this Form 4) and, as directed by the Compensation Committee of the Issuer's Board of Directors on May 22, 2017, vested at target. The original aggregate number of PSUs granted to the Reporting Person under the PSU Grants were reported in Table II of the applicable Form 4s filed by the Reporting Person in connection with each such grant. ( 2 )In addition, of the 47,917 total shares of Common Stock that vested under the PSU Grants following the closing of the Mergers, the Reporting Person delivered 23,453 shares to the Issuer for payment of tax liability incident to the vesting of a security, as detailed in Footnote 3 to this Form 4.

In the Mergers, each share of Issuer Common Stock was exchanged for one share of common stock, par value $0.0001 per share, of Sonus Networks ("New Common Stock"). ( 5 )The closing price of a share of Issuer Common Stock on October 27, 2017 (the last trading day prior to the effectiveness of the Mergers) was $8.14, and the closing price of a share of New Common Stock on October 30, 2017 (the first trading day following the effectiveness of the Mergers) was $8.39. ( 6 )The 2015 PSU Grant was assumed by Sonus Networks in connection with the Mergers. Between zero percent (0%) and 120% of the remaining shares subject to the 2015 PSU Grant will vest into New Common Stock, if at all, on March 16, 2018. ( 7 )The 2016 PSU Grant was assumed by Sonus Networks in connection with the Mergers. Between zero percent (0%) and 200% of one-half of the remaining shares subject to the 2016 PSU Grant will vest into New Common Stock, if at all, on each of April 1, 2018 and April 1, 2019. ( 8 )The 2017 PSU Grant was assumed by Sonus Networks in connection with the Mergers. Between zero percent (0%) and 200% of one-third of the remaining shares subject to the 2017 PSU Grant will vest into New Common Stock, if at all, on each of March 31, 2018, March 31, 2019 and March 31, 2020.
