Page 5 of 7 Pages

The following constitutes Amendment No. 3 to the Schedule 13D filed by the undersigned ("Amendment No. 3"). This Amendment No. 3 amends the Schedule 13D as specifically set forth herein.

Item 4.

PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is hereby amended and supplemented by the addition of the following:

On February 11, 2019, pursuant to the terms of the Merger Agreement, Merger Sub merged with and into the Issuer, with the Issuer surviving the Merger as a wholly-owned subsidiary of Parent.

At the Effective Time, each share of Common Stock issued and outstanding as of immediately prior to the Effective Time (other than Excluded Shares) was converted into the right to receive the Merger Consideration and all such shares of Common Stock were cancelled and cease to exist. Prior to the Effective Time, the Elliott Funds contributed their shares of Common Stock to Parent for cancellation at the Effective Time without payment of any consideration therefor.

At the Effective Time, the Issuer's certificate of incorporation, as in effect immediately prior to the Merger, was amended and restated in its entirety to read identically to the certificate of incorporation of Merger Sub, and Merger Sub's bylaws, as in effect immediately prior to the Merger, became the bylaws of the Issuer.

Following the closing of the Merger, the shares of Common Stock that previously traded under the ticker symbol "ATHN", ceased trading on, and were delisted from, the NASDAQ Global Select Market, in each case as of the close of business on February 11, 2019. In addition, the shares will be deregistered under the Securities Exchange Act of 1934, as amended.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Merger Agreement, which was incorporated as Exhibit 99.2 to Amendment No. 2 to the Schedule 13D by reference to Exhibit 2.1 to the Issuer's Current Report on Form 8-K filed on November 13, 2018.
