The Board has approved the general terms of a Multi-Year Outperformance Agreement (the “OPP”) to be entered into with the Company, the American Realty Capital Global Operating Partnership, L.P. (the “Operating Partnership”), and the Advisor, in connection with the Listing.

Under the OPP, Advisor will be issued LTIP units in the Operating Partnership with a maximum award value equal to 5% of the Company’s market capitalization (the “OPP Cap”) on the date of Listing (the “Effective Date”). The LTIP units will be structured as profits interests in the Operating Partnership. The Advisor will be eligible to earn a number of LTIP units with a value equal to a portion of the OPP Cap based on the Company’s achieving certain levels of total return to its stockholders (“Total Return”) on both an absolute basis and a relative basis measured against a peer group of companies, as set forth below, for a three-year period commencing on the Effective Date (the “Performance Period”). In addition, Advisor may “lock-in” a portion of the OPP Cap based on the attainment of pro-rata performance hurdles, as set forth below, during each 12-month period in the Performance Period (each such period, an “One Year Period” and during the initial 24-month period of the Performance Period (the “Two-Year Period”). Each of the relevant performance periods will be evaluated separately based on performance through the end of the relevant performance period.

*The “Peer Group” is comprised of Chambers Street Properties, Gramercy Property Trust Inc., Lexington Realty Trust, Select Income REIT, and W.P. Carey Inc.

The maximum “lock-in” amount for any given One-Year Period is 25% of the OPP Cap. The maximum “lock-in” amount for the Two-Year Period is 60% of the OPP Cap. Accordingly, any “lock-in” amount for the Two-Year Period may supersede and negate any awards for the first two One-Year Periods. Any LTIP Units that are unearned at the end of the Performance Period will be forfeited.

Subject to Advisor’s continued service through each vesting date, one third of any earned LTIP units will vest on each of the third, fourth and fifth anniversaries of the Effective Date. Any earned and vested LTIP Units may be converted into OP Units of the Operating Partnership in accordance with the terms and conditions of the partnership agreement of the Operating Partnership.

The OPP provides for early calculation of LTIP Units earned and for the accelerated vesting of any earned LTIP Units in the event Advisor is terminated by the Company or in the event the Company incurs a change in control, in either case prior to the end of the Performance Period. The OPP also provides for accelerated vesting of earned LTIP Units in the event Advisor is terminated or in the event of a change in control of the Company on or following the end of the Performance Period.

The description of the OPP in this Current Report on Form 8-K is a summary and is qualified in its entirety by the terms of the executed OPP, a copy of which will be filed as an exhibit to the Company’s Current Report on Form 8-K filed in connection with its execution.
