Explanation of Responses:

1. Morgan Stanley GWM Feeder Strategies LLC is the managing owner of the reporting person, and is a wholly-owned subsidiary of Morgan Stanley Smith Barney Holdings LLC. Morgan Stanley Smith Barney Holdings LLC is indirectly majority-owned by Morgan Stanley.

2. The Issuer delivered a drawdown notice on December 16, 2011, and upon receiving the drawdown notice, the reporting person became obligated to make a capital contribution of $2,379,214 to purchase 2,425 shares of Common Stock at a price of $981.12 per share.

3. Although MSSB TPG Specialty Lending Onshore Feeder Fund (the "Trust") beneficially owns 33,481 shares of the common stock of the Issuer and would otherwise be entitled to vote such shares, the Trust has contractually agreed to pass such voting rights through to the Trust's underlying investors (each a "Unitholder" and collectively, the "Unitholders") pro rata in accordance with each Unitholder's relative ownership of units of the Trust. Each Unitholder will make its own determination as to how to vote with respect to its portion of the Trust's shares of the Issuer, as well as whether or not to vote with respect to such shares. If Unitholders representing a certain percentage vote their interests, the Trust will vote all shares in accordance with the votes received. If, however, less than the agreed upon representative vote is received, the Trust will not vote any of the shares.
