Item 4. Purpose of Transaction

The information previously provided in response to Item 4 is hereby amended and supplemented by adding the following at the end thereof:

On March 5, 2013, TWC and the Issuer entered into a Common Unit Purchase Agreement (the “Common Unit Purchase Agreement”) providing for the issuance and sale to TWC (the “Private Placement”) of 3,000,000 Common Units in a private placement transaction in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended. The Private Placement closed on March 8, 2013. The Common Units issued in the Private Placement were sold to TWC at a price per Common Unit of $47.66, which is equal to the public offering price in the Issuer’s concurrent underwritten public offering of 11,250,000 Common Units, less the underwriting discount and commissions in such offering. The aggregate purchase price in the Private Placement was approximately $143.0 million, paid for with TWC’s cash on hand.
