Post and Williams each have received last-minute support from name groups. Green Street Advisors, a New York-based real estate investment sales research firm, joins Institutional Shareholders Services Inc. of Rockville, MD in urging stockholders to vote for Post's existing slate of directors and management.

In Williams' corner, Sam Shapiro, president, Shapiro Capital Management of suburban Buckhead, GA, has come out strongly for Williams' corporate candidates, according to a published report.

Shapiro couldn't be reached at GlobeSt.com's publication deadline. But according to the report, the financier is going with Williams after learning Post directors didn't notify shareholders of a March company buyout offer of $26 per share from General Investment & Development Co. Inc. of Boston. Shapiro considers that a flagrant abuse of corporate governance, according to the report.
