It appears that the insiders are lining themselves up to take advantage of successful BETonMACE results. They have gifted over $5 million (at today's closing price) worth of rights to themselves at no cost. If the trial is successful, they can then vest them and receive the shares. If it fails, they hold them into the future at no cost or vest them at wherever the price collapses to. DM's portion is worth $1,345,360 at today's closing price. A show of confidence in BoM would be if they were to vest them between now and TLD announcement. Then they would have a tax liability for the vesting value but RVX would have to come up with the tax money to submit the withheld taxes.
