Sales of the Units, if any, will be made by means of ordinary brokers’ transactions on the NASDAQ Global Select Market at market prices or in block transactions.

Under the terms of the Agreements, the Partnership may also sell Units from time to time to either of UBS or Knight as principal for its own account at a price and upon terms to be agreed upon at the time of any such sale. Any sale of Units to UBS or Knight as principal would be pursuant to the terms of a separate terms agreement between the Partnership and UBS or Knight.

The Units will be issued pursuant to the Partnership’s existing effective shelf registration statement on Form S-3 (Registration No. 333-163554).
