Explanation of Responses:

( 1 )Each unit represents a contingent right to receive one common share or an equivalent amount of cash, or a combination of the two, at the discretion of BlackBerry Limited ("BlackBerry"). ( 2 )Sales to cover withholding taxes upon vesting of Restricted Share Units ("RSUs")". ( 3 )The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $10.90 to $11.73, exclusive of any fees, commissions or other expenses. The Reporting Person undertakes to provide BlackBerry, any shareholder of BlackBerry, or the Staff of the SEC, upon request, full information regarding the number of shares sold at each separate price within the range set forth in this footnote. ( 4 )This award was granted on April 10, 2018 and, assuming continued employment through the applicable vesting date, vests in five equal annual instalments ending November 3, 2023. ( 5 )This award was granted on April 10, 2018. Performance-Based RSUs may be earned in increments of one million common shares of BlackBerry when the 10-day trading average price of BlackBerry's common shares on the New York Stock Exchange reaches $16, $17, $18, $19 and $20, respectively. If earned, the increment will vest on the first anniversary of November 3, 2018, 2019, 2020, 2021 or 2022, respectively, that follows the date on which they are earned. Any Performance-Based RSUs that have not been earned before November 3, 2023 will terminate on such date.

Remarks: This amendment is being filed to address an error in the footnote describing the terms of vesting of the Performance-Based RSUs.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
