After a few months of pointed exchanges, Aladdin Knowledge Systems and its would-be buyer, Vector Capital, have agreed to a standstill in an attempt to negotiation a deal. Vector, the encryption vendor’s largest shareholder, had been pushing for a shareholder vote on Oct. 23 on its plan to replace three of Aladdin’s five board members. The buyout firm has set aside that demand, as well as agreeing not to unload any of its 14% holding. For its part, Aladdin agreed to sign a confidentiality agreement with Vector, and will not to seek another buyer for part or all of its business. Last month, Vector offered $13 for each share of Aladdin; the stock currently trades above that. The standstill gives the two sides at least a month to work out a deal, as Vector can’t call for another shareholder meeting until Oct. 30 at the earliest.
