Right. Instead of the IPO date, or the end of the lockup date, they chose 3/15 as the date to settle the vested RSU. And require us to estimate our tax, based on the fair market value of that future date, with this formula, and pay cash, otherwise the vested RSU will be canceled:

Number of vested RSUs * the estimated fair market value of the stock at the settlement date * the appliable highest marginal federal, state, local income tax rate and employment tax rate.

In theory if someone pump up the stock price for that date, we are screwed. Even if no one pump up the stock price, the amount of cash needed in such a short notice, is unbearable, which will make most ex-employees to give up their shares.
