With minutes to spare before the filing deadline Tuesday evening, Clearwire (NASDAQ: CLWR) filed a rash of Statement of Changes in Beneficial Ownership documents with the Securities and Exchange Commission.

All told, 18 Form 4s were filed, each indicating a Clearwire award of restricted stock units, or RSUs, to 12 of the 13 members of the company's board of directors, and to seven of its executives, including its CEO, Erik Prusch (also a board member), and its CFO, Hope Cochran.

The RSUs were granted on March 1. For the executives, they will begin vesting on March 1, 2014 over a period of four years. For the directors, except for CEO Prusch, the RSUs will become vested on March 1, 2014.

Of particular interest in the filings for the executives is footnote No. 2, which states: "In the event that the Company's pending merger with Sprint closes, at the effective time of the merger, these RSUs will be converted into a right to receive a cash payment upon vesting equal to the product of the merger consideration."

That footnote refers to the proposed merger with Sprint Nextel (S) and the $2.97 a share that Clearwire's board voted to accept for giving full control of the company to Sprint.

Given the number of RSUs awarded, for which the recipients paid $0.00, the paydays could range from "quite a bit" for the executives, to "not too bad" for the directors.

Here's the breakdown:

Whether or not the Sprint deal does close, the above-named will still get their RSUs. They just won't be able to convert them to a lump sum cash payout for the directors, or have them converted into what Clearwire calls a "Restricted Cash Account" for the executives.

However, there is always the possibility of the merger not consummating. DISH Network (DISH) put up one hurdle in the form of a counteroffer to Sprint's, one that would pay $3.30 a share for the company.

Another obstacle is dissatisfaction with the merger deal from some major Clearwire stockholders. Mount Kellett Capital Management, holder of a 7.3% share of Clearwire shares, and Crest Financial, with 8.3%, have already complained to the Federal Communications Commission about the proposal.

Crest also filed a lawsuit (link opens PDF) against Clearwire, Clearwire's board of directors, and Sprint, to stop the deal. It accused Sprint, which already had a controlling interest in Clearwire, of not allowing Clearwire to engage in a fair process of selling "either Clearwire or its assets for the benefit of all Clearwire stockholders."  Instead, Sprint "launched a scheme to deliver unilateral control of Clearwire and its spectrum assets" to Sprint's buyer SoftBank "on the cheap, while extracting maximum benefit for itself."

But whether or not Clearwire's stockholders manage to thwart the takeover, even DISH's notoriously tenacious chairman, Charlie Ergen, admitted that his company taking control of Clearwire was not likely to happen. "The deck is stacked against us," he told a group gathered at an AllThingsD conference last month.

That could mean some big payouts are coming up for Clearwire's executives and directors, something they could not have envisioned a year ago when the company threatened to default on a $237 million interest payment on its $4 billion in debt.

But that was another Clearwire era.
