Upon a reasonable request by the Acquired Fund, each Acquiring Fund will provide summary information regarding the anticipated timeline of its investment in the Acquired Fund and the scale of its contemplated investments in the Acquired Fund. The Acquired Fund acknowledges and agrees that any information provided pursuant to the foregoing is not a commitment to purchase and constitutes an estimate that may differ materially from the amount, timing and manner in which a purchase order is submitted, if any.

Such fee and expense information shall be limited to that which is made publicly available by the Acquired Fund.
