Restricted Stock Unit financial

"Each Restricted Stock Unit represents a contingent right to receive one share"

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

Change in Control financial

"shall vest in full subject to Participant's continued Service through to the date of a Change in Control"

A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.

2nd Amended and Restated 2008 RSU Plan financial

"delivered to the reporting person pursuant to the terms of the 2nd Amended and Restated 2008 RSU Plan"
