Upon request, the undersigned will execute and deliver any additional documents necessary to complete the sale in accordance with the terms of the Offer.

The undersigned recognizes that under certain circumstances set forth in the Offer, the Fund may not be required to purchase any of the Shares of the Fund or portion thereof tendered hereby.
