Equity Offerings

The Partnership has an At the Market offering program (the “ATM”) in place with a financial institution (the “Manager”) which allows the Partnership from time to time, through the Manager as its sales agent, to offer and sell common units representing limited partner interests in the Partnership. Sales of such common units are made by means of ordinary brokers’ transactions on the NYSE at market prices, in block transactions or as otherwise agreed upon by the Manager and the Partnership. The Partnership may also sell common units to the Manager as principal for its own account at a price to be agreed upon at the time of the sale. For any such sales, the Partnership will enter into a separate agreement with the Manager. During the six months ended June 30, 2013, the Partnership sold an aggregate of 5.7 million common units under the ATM, receiving net proceeds of approximately $348.4 million after deducting approximately $5.2 million in manager fees and other third-party expenses. The proceeds from sales were used to fund capital expenditures and for general partnership purposes.
