Since the filing of Amendment No. 3 to Schedule 13D on June 9, 2006, there
have been changes to the executive officers of the managing member of
Saddlepoint GP.  Blum LP is the managing member of Saddlepoint GP and its
executive officers are listed above.

To the best knowledge of the Reporting Persons, none of the entities or
persons identified in this Item 2 has, during the past five years, been
convicted of any criminal proceeding (excluding traffic violations or
similar misdemeanors), nor been a party to a civil proceeding of a judicial
or administrative body of competent jurisdiction and as a result of such
proceeding was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to,
federal or state securities laws or finding any violation with respect to
such laws.


Item 5.  Interest in Securities of the Issuer
---------------------------------------------

(a), (b) According to the Issuer's Form 10-Q with the Commission on November
9, 2006, there were 67,986,803 shares of Common Stock issued and outstanding
as of October 31, 2006.  Based on such information, after taking into account
the transactions described in Item 5(c) below, the Reporting Persons report
beneficial ownership of the following shares of Common Stock: (i) 1,454,010
shares of Common Stock held by Blum LP and RCBA Inc. on behalf of the limited
partnerships for which Blum LP serves as the general partner, which represents
2.1% of the outstanding shares of the Common Stock; (ii) 4,897,600 shares of
the Common Stock held by Blum GP III which serves as general partner of Blum
GP III LP which, in turn, serves as the general partner of Blum Strategic III,
which represents 7.2% of the outstanding shares of the Common Stock;
(iii) 238,500 shares of the Common Stock held by Saddlepoint GP on behalf of
a partnership for which it serves as the general partner, which represents
0.4% of the outstanding shares of the Common Stock; and (iv) 86,300 shares
of the Common Stock that are legally owned by The Nuclear Decommissioning
Trust of Dominion Nuclear Connecticut, Inc. ("Dominion Connecticut"), which
represents 0.1% of the outstanding shares of the Common Stock and 86,300
shares of the Common Stock that are legally owned by Virginia Electric and
Power Company Qualified Nuclear Decommissioning Trust ("Virginia Electric"),
which represents 0.1% of the outstanding shares of the Common Stock
(collectively, the "Investment Advisory Clients"), with respect to which
Blum LP has voting and investment power.  Each Investment Advisory Client
has entered into an investment management agreement with Blum LP, but
neither Investment Advisory Client has any contract, arrangement or
understanding with the other Investment Advisory Client, or any other
Reporting Person, with respect to the acquisition, ownership, disposition
or voting of any shares of the Common Stock.  Each Investment Advisory
Client disclaims membership in a group with any Reporting Person or with
the other Investment Advisory Client, and each disclaims beneficial ownership


CUSIP NO. 67018T105            SCHEDULE 13D                     Page 11 of 12


of any shares beneficially owned by the Reporting Persons other than for their
own account.

Voting and investment power concerning the above shares are held solely by
Blum LP, Blum GP III and Saddlepoint GP.  The Reporting Persons therefore may
be deemed to be members in a group, in which case the group would be deemed
to have beneficial ownership of an aggregate of 6,762,710 shares of the Common
Stock, which is 9.9% of the outstanding Common Stock.  As the sole general
partner of Blum LP, RCBA Inc. is deemed the beneficial owner of the securities
over which Blum LP has voting and investment power.  The filing of this
Schedule shall not be construed as an admission that any of the shareholders,
directors or executive officers of RCBA Inc. or the managing members and
members of Blum GP III, Blum GP III LP and Saddlepoint GP, is, for any purpose,
the beneficial owner of any of the securities that are beneficially owned by
RCBA Inc., Blum GP III LP, Blum GP III or Saddlepoint GP.

c) During the last 60 days, the Reporting Persons sold the following shares of
Common Stock to a broker in a block sale:


Entity                            Trade Date   Shares     Price/Share
------                            ----------   --------   ------------
Investment partnerships for        12-05-06   1,300,000    18.2100
which Blum LP serves as the
general partner and on behalf
of an entity for which Blum LP
serves as investment advisor.



(d) and (e)  Not applicable.
