"We believe that PGRT is attempting to renegotiate a substantiveprovision regarding the structure of the merger to which it hadpreviously agreed," Mansur argues. "Negotiations are ongoingbetween our organization and Prime Group attempting to overcome ourdifferences and complete the planned merger."

Prime Group Realty Trust president and chief executive officerJeffrey A. Patterson declined further comment on the Prime/Mansurbid during last week's earnings conference call.

"We are optimistic that our discussions with management willlead to a resolution of our dispute and a closing of the Primeacquisition in the near future," Mansur adds. "However, if thesenegotiations are not successful, we will pursue all legal remediesavailable to us, including the enforcement of the merger agreement,which we deem to be valid and in full force and effect."
