Exhibit 99.2

FPO Employee Letter

June 28, 2017

Dear First Potomac Team:

Earlier today we announced that, following a thorough review of strategic alternatives, our Board of Trustees has unanimously approved a definitive merger agreement under which Government Properties Income Trust (GOV) will acquire First Potomac for $11.15 per share. A copy of the press release is attached to this email.

As many of you know, GOV is a real estate investment trust that primarily owns properties leased to government tenants. Given our operations in the Washington D.C. region and the complementary nature of our businesses, we are confident that GOV is the ideal strategic partner for First Potomac. GOV is a proven operator with a solid financial foundation.

Over the last 18 months we have worked diligently to strengthen and improve First Potomac, and this attractive outcome for shareholders is clear evidence of our success. On behalf of the Board, I thank you for helping us achieve this result for our shareholders.

Today’s announcement is only the first step. The transaction, which is expected to close prior to year end 2017, remains subject to customary closing conditions, including approval by First Potomac shareholders. Until the transaction closes, First Potomac and GOV will continue to operate as two separate companies and it will generally remain business as usual. During this time of transition, we ask that you remain as focused as always on your responsibilities.

We understand that you may have questions about what today’s announcement means for you. We will do our best to keep you informed as updates are available. We will be holding meetings over the coming days to discuss this announcement and what it means for First Potomac employees. In the meantime, please direct any immediate questions to Fadwa Hasan in Human Resources at fhasan@first-potomac.com or (240) 223-0732.

Please also remember that it’s important for us to speak with one voice. If you receive any inquiries from the media, please forward them to Briean Cargill at bcargill@first-potomac.com or (240) 235-5523. If you receive any inquiries from analysts or investors, please forward them to Randy Haugh at rhaugh@first-potomac.com or (240) 235-5573.

I am very proud of all that we have accomplished together and thank each of you for your continued dedication.

Sincerely,

Bob Milkovich

Chief Executive Officer
