Here's some context in case it's relevant. I worked at a startup which issued shares (not options) to employees. A good chunk of my shares have vested over the 4-year vesting period. I have voluntarily quit without being fully vested. The company would like to purchase all my shares back. I understand that I don't get to keep my unvested shares, but I'm under the impression that the vested shares are mine to keep. I have already bought them and paid the taxes. I filled out IRS form 83b.
This is the relevant part of my shareholder agreement
if such person’s employment is terminated without Cause, such person shall only be required to sell his or her Unvested Shares hereunder and shall not be required to transfer his or her Vested Shares.
I was not terminated. I voluntarily quit and left in good standing. The shareholder's agreement doesn't seem to address what happens to employee shares if they quit.
What's the default here? That is, if there was no mention of share buyback, is the company allowed to purchase my shares without my agreement?
What recourse do I have if they insist on buying it back?
What happens if I simply refuse to sign any offer deal?
Thank you in advance for you time
