Terms defined in the Schedule 13D are used herein as so defined.

The following Items of the Schedule 13D are hereby amended as follows:

Item 4. Purpose of Transaction.

The information in Item 4 is hereby amended and supplemented as follows:

On July 15, 2011, the transactions contemplated by the Merger Agreement described in Amendment No. 12 to the Schedule 13D were consummated. Each outstanding share of the Issuer’s Common Stock was converted into the right to receive (a) $30.00 in cash and (b) 0.2479 of a share of CenturyLink common stock (which fraction was calculated using the formula set forth in the Merger Agreement, by dividing $10.00 by the volume-weighted average trading price of CenturyLink common stock over the thirty-day trading period ending on July 12, 2011), with cash paid in lieu of fractional shares. Merger Sub merged with and into the Issuer, with the Issuer continuing as the surviving corporation and a wholly-owned subsidiary of CenturyLink. Following the completion of the Merger, on July 15, 2011, the NASDAQ Global Select Market (“NASDAQ”) filed with the Commission a Form 25 removing the Common Stock from listing on NASDAQ and registration under Section 12(b) of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”). Additionally, the Issuer intends to file with the Commission, ten days after the filing of the Form 25, a Form 15 terminating the registration of the Common Stock under Section 12(g) of the Exchange Act.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.
