The current term of the Management Agreement expires on September 29, 2014 and shall be automatically renewed for successive one-year terms on each anniversary thereafter. The Management Agreement may be terminated upon expiration of the one-year extension term only upon the affirmative vote of at least two-thirds of the Company’s independent directors, based upon (1) unsatisfactory performance by the Manager that is materially detrimental to the Company or (2) a determination that the management fee payable to the Manager is not fair, subject to the Manager’s right to prevent such a termination based on unfair fees by accepting a mutually acceptable reduction of management fees agreed to by at least two-thirds of the Company’s independent directors. The Manager must be provided with written notice of any such termination at least 180 days prior to the expiration of the then existing term and will be paid a termination fee equal to three times the sum of the average annual base management fee during the 24-month period immediately preceding the date of termination, calculated as of the end of the most recently completed fiscal quarter prior to the date of termination. Following a meeting by the Company’s independent directors on March 12, 2013 with respect to the Management Agreement, which included a discussion of the Manager’s performance and the level of the management fees thereunder, the Company determined not to seek termination of the Management Agreement.

KBCD also is active in real estate financing, acquisition finance, institutional cash, interest and currency management and private wealth management for German high net worth individuals.

Upon closing of the KBCD acquisition it is expected that the KBCD Partnership will incur a structuring fee payable to an indirect subsidiary of Apollo equal to approximately 1.62% of the equity commitments to the KBCD Partnership. In addition, a subsidiary of the KBCD Partnership will be entitled to acquire additional shares in KBCD representing up to 10% of KBCD in connection with certain exit events, based on the achievement of certain rates of return on the investments by the KBCD Partnership and the other direct and indirect acquirers of KBCD; the Company’s indirect interest in KBCD will be diluted in connection with any such acquisition.
