CEO, chairman resign at Blue Bell's UniTek

Urban Outfitters isn't the only local company to change CEOs this week.

Blue Bell-based UniTek Global Services, which does the construction and other grunt work for cable TV and telecommunications providers, said C. Scott Hisey resigned as president and CEO as did Peter Giacalone as chairman of the board.

The moves are effective immediately, the company said in a statement. Hisey will remain a board member, but not Giacalone.

The board created an "interim Office of CEO" that will be managed by Dan Yannantuono, who is the CEO of DirectSat (a UniTek division), and Ronald J. Lejman, UniTek's chief financial officer.

Michael F. O'Donnell was named the new chairman of of UniTek, which has a workforce of about 6,500 people and expects to report 2011 revenues of $440 million. Here's a link to UniTek's announcement.

Also, Philadelphia-based Hemispherx Biopharma said that the U.S. Food and Drug Administration granted the company's request for an extension on modifying its New Drug Application for its long-in-development experimental treatment for chronic fatigue syndrome. How long? The company did not provide a timetable.
