More Top Execs Bolt from BlackBerry

More Top Execs Bolt from BlackBerryTwo more longtime BlackBerry executives have left the embattled Canadian smartphone-maker.

We learned late Monday that the latest resignations represent the fifth and sixth top executive departures in as many weeks.

Rick Costanzo, executive vice president for global sales, and Chris Wormald, vice president for Strategic Alliances, are both out at BlackBerry, having voluntarily stepped down to pursue other endeavors.

In September, the company announced that close to 40% of its workforce would be laid off.

By November, BlackBerry CEO Thorsen Heins was out in the wake of news that BlackBerry had entered into an agreement pursuant to which Fairfax Financial Holdings Limited and other institutional investors will invest in BlackBerry to the tune of $1 billion.
