I don't think that they can "negotiate" on a case by case basis as that would not be considered "fair" to all common shareholders; also, as they have not commissioned a formal company "valuation", they are unable to establish a fixed price at which it would be "fair" to buy back shares.
With that said, however, if an individual shareholder chose to offer some (or all) of their shares at a specified price to the company, they could either accept or decline the offer as I understand it. I don't know if they have created some sort of form that could be used as a way to extend an offer.
