CarrAmerica

    WASHINGTON, June 1 /PRNewswire/ -- CarrAmerica Realty Corporation (NYSE:
CRE) today announced its closing on a transaction that merges its executive
office suites affiliate, HQ Global Workplaces, Inc., with Vantas Incorporated,
the executive office suites subsidiary of FrontLine Capital Group (Nasdaq:
FLCG). CarrAmerica and certain other shareholders in HQ Global Workplaces
received cash in the transaction. FrontLine Capital Group and other equity
investors now own an approximate 74% common equity interest in the merged
company with CarrAmerica retaining an approximately 26% common equity interest
(approximately 16% after the conversion of preferred stock to common stock and
exercise of warrants) valued in the transaction at $120 million. Other new

    In addition to retaining an interest in HQ Global Workplaces, CarrAmerica
Chairman and Chief Executive Officer, Thomas A. Carr, will join the HQ Global
Workplaces' Board of Directors.
    Mr. Carr commented on the transaction, saying, "We are excited about HQ
Global's future as they firmly position themselves as the global leader in
flexible workspace solutions." Mr. Carr continued, "CarrAmerica will continue to
explore new avenues for growth that build value for our customers and
shareholders, just as we have done with HQ Global and our early investments in
the executive office suites business."

accounted for as an investment under cost accounting methods.

FrontLine Capital Group. CarrAmerica received approximately $210 million in cash
proceeds which will be used primarily to repay debt, to fund CarrAmerica's stock
repurchase program and for other general corporate purposes. HQ Global
Workplaces also repaid $141 million of debt, which was guaranteed by
CarrAmerica.
    Goldman Sachs acted as exclusive financial advisor to CarrAmerica in this
transaction.
