On May 8, 2012, West announced that it intends to commence an offering of senior debt securities in a private placement (the “Private Placement”) exempt from registration under the Securities Act.  West expects to use the net proceeds of the Private Placement to refinance amounts that it anticipates it will borrow under its revolving credit facility to pay the purchase price for the Debentures that it accepts for purchase in the Offer.  A copy of the press release is filed as Exhibit 99.2 to this report and incorporated herein by reference.

West does not intend to register the senior debt securities under the Securities Act, and the senior debt securities may not be offered or sold in the United States absent registration under, or an applicable exemption from, the registration requirements of the Securities Act.
