There's NO "vote" necessary. That is merely a STALL tactic and a means to direct the exchange toward insider's desired result. The terms state that each shareholder may choose between 20 cents CASH or 20 cents worth of shares at the market price at redemption.
Series C shareholders would be foolish to take the shares, which would be restricted and immediately lose value through the massive dilution.
Series C shareholders only have until February to redeem their certs. After that, they're worthless. Hence the delaying tactics.
If I held a significant amount, I'd contact a lawyer immediately and have him request an immediate exchange for cash. These TURDS knew about the Series C shares when they took over the company, it's no surprise to them.
