~~As previously disclosed, in June 2008 Prime Group Realty Trust~~ (~~the “Company”~~b) instituted a retention and severance program for its corporate employees (the “Existing Retention Plan”), including four of the Company’s officers who were named executive officers in the Company’s Summary Compensation Table contained in the Company’s Form 10-K for calendar year 2006. The Existing Retention Plan was effective for a two-year period and accordingly was scheduled to expire in June ~~2010.~~Exhibits:


Exhibit
No.		Description

99.1		Prime Group Realty Trust First Quarter Ended March 31, 2010 Earnings Press Release dated May 13, 2010.

~~On April 30, 2010, the Company~~SIGNATURE instituted an updated retention plan (the “Retention Program”) that replaced and extended the Existing Retention Plan. The participants in the Retention Program include four officers who are named executive officers in the Company’s Summary Compensation Table contained in the Company’s Form 10-K for calendar year 2009, consisting of our President and Chief Executive Officer, Mr. Patterson (our “CEO”), our Senior Executive Vice President, General Counsel and Secretary, Mr. Hoffman (our “General Counsel”), our Executive Vice President – Capital Markets, Mr. Del Vecchio (our “EVP”) and our Senior Vice President – Leasing, Mr. Baron (our “SVP”). The Retention Program was developed in consultation with FPL Associates, L.P. (“FPL”), a leading compensation consulting firm, who the Company engaged as its independent compensation consultant. The Retention Program provides for the payment of a retention payment in the event a participant is terminated without cause by the Company, the participant terminates his or her employment with the Company for “good reason” or upon the occurrence of a “qualifying event” as defined below (a “Triggering Event”). A participant will not be entitled to a retention payment if the participant voluntarily resigns or if the Company terminates the participant’s employment for cause. A participant will be entitled to terminate his or her employment with the Company for “good reason” upon the occurrence of any of the following events: material breach by the Company of the terms of the Retention Program or certain other wrongful action by the Company relating to the participant’s employment, the death or disability of the participant, a relocation of the participant’s office location to a place more than twenty-five miles from the current location or a material diminution in the duties, responsibilities or compensation of the participant. A “qualifying event” means the purchase, sale, redemption, recapitalization or other transaction (whether by merger or otherwise) resulting in the Company’s Series B Preferred Shares no longer being outstanding or the terms thereof being substantially changed.

~~For~~Pursuant ~~our~~to ~~CEO, General Counsel and EVP,~~ the ~~amount~~requirements of the ~~payment~~Securities ~~upon~~Exchange ~~the~~Act ~~occurrence~~ of ~~a Triggering Event (the “Retention Payment”) was calculated based on a formula of two months of base salary for each year of service with the Company~~1934, ~~capped at a payment equal to 36 months of base salary. Upon~~ the ~~occurrence~~Registrant ofhas aduly ~~Triggering~~caused ~~Event,~~ this ~~will~~report ~~result in fixed payments~~ to ~~our~~be ~~CEO,~~signed ~~General Counsel~~on ~~and~~its ~~EVP~~behalf ofby ~~35 months, 32 months and 24 months of their base salary, respectively. For our SVP,~~ the ~~Retention~~undersigned ~~Payment~~hereunto isduly ~~fixed at 9 months of his base salary~~authorized.

The Company did not pay annual bonuses to its employees for calendar year 2009 and only paid partial bonuses to its employees for calendar year 2008. In an effort to retain key personnel in light of the foregoing and in light of other factors affecting the Company, the Retention Program provides that a percentage of the Retention Payment (the “Interim Payments”) will be paid if the participant is employed full-time at the time of the payment as follows: (i) for the CEO, 18%, for the General Counsel and EVP, 15%, and for the SVP 16%, in June, 2010; and (ii) for the CEO, 27%, and for the General Counsel, EVP and SVP, 28%, in December 2010. These Interim Payments are deducted from the Retention Payment for each individual and the remaining amount of the Retention Payment is payable only upon the occurrence of a Triggering Event.
