SCHEDULE 13D -------------------------- ------------------------- CUSIP NO. 018581108 Page 10 of 14 ----------------------------------------------------------------------------- Item 5. Interest in Securities of the Issuer (a) and (b). Set forth below is the beneficial ownership of shares of Common Stock of the Issuer for each person named in Item 2. Shares reported as beneficially owned by ValueAct Master Fund are also reported as beneficially owned by (i) ValueAct Management L.P. as the manager of each such investment partnership, (ii) ValueAct Management LLC, as General Partner of ValueAct Management L.P., (iii) ValueAct Holdings, as the majority owner of the membership interests of VA Partners I, (iv) ValueAct Holdings II, as the sole owner of the limited partnership interests of ValueAct Management L.P. and the membership interests of ValueAct Management LLC, and (v) ValueAct Holdings GP, as General Partner of ValueAct Holdings and ValueAct Holdings II.

As of the date hereof, the Reporting Persons may be deemed to be the beneficial owner of an aggregate of, 5,207,646 shares of Common Stock, representing approximately 9.9% of the Issuer's outstanding Common Stock. Such shares of Common Stock includes 150,000 shares of Series A Non-Voting Convertible Preferred Stock, par value $0.01 per share, of the Issuer ("Series A Non-Voting Convertible Preferred Stock"), each share of which is convertible into ten (10) shares of Common Stock upon the election of the holder thereof.

Item 6.

Under the terms of the Certificate of Designations of the Series A Non-Voting Convertible Preferred Stock (the "Certificate of Designations"), the Series A Non-Voting Convertible Preferred Stock will not entitle the holder thereof to any voting rights, unless required by the General Corporation Law of the State of Delaware. Each share of Series A Non-Voting Convertible Preferred Stock may be converted into ten (10) shares of Common Stock upon the election of the holder thereof (subject SCHEDULE 13D -------------------------- ------------------------- CUSIP NO. 018581108 Page 11 of 14 ----------------------------------------------------------------------------- to certain adjustments as set forth in the Certificate of Designations); provided that upon such conversion, the holder, together with its affiliates, will not own or control in the aggregate more than 9.9% of the outstanding Common Stock. Furthermore, each share of Series A Non-Voting Convertible Preferred Stock will automatically convert into ten (10) shares of Common Stock upon the transfer of such shares by a fund advised by ValueAct Holdings to an unaffiliated third party, subject to certain exceptions.
