Postal Instant Press said it agreed to an amended proposal to take the company private under which shareholders would receive $15.50 a share instead of the previously reported $17.41-a-share offer from a company formed by senior PIP managers and the Chicago leveraged buyout concern Golder, Thoma & Cressey. The buyout group was unable to secure suitable financing for the higher offer, PIP said.
