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

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

(a), (b) According to the Issuer's Form 10-Q filed with the Securities and
Exchange Commission on November 9, 2005, there were 70,295,248 shares of
Common Stock issued and outstanding as of October 31, 2005.  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) 1,555,200 shares of Common Stock held
by Blum L.P. and RCBA Inc. on behalf of the limited partnerships for which
Blum L.P. serves as the general partner, or on behalf of an entity for which
Blum L.P. serves as investment advisor, which represents 2.2% of the
outstanding shares of the Common Stock; (ii) 3,441,000 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 4.9% of the outstanding shares of the Common Stock; (iii) 151,700
shares of the Common Stock held by Saddlepoint GP on behalf of a partnership
for which it serves as the general partner, which represents 0.2% of the
outstanding shares of the Common Stock; and (iv) 45,500 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 45,500 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
 


CUSIP NO. 67018T105            SCHEDULE 13D                     Page 9 of 11

the outstanding shares of the Common Stock (collectively, the "Investment
Advisory Clients"), with respect to which Blum L.P. has voting and investment
power.  Each Investment Advisory Client has entered into an investment
management agreement with Blum L.P., 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 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 L.P., 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 5,238,900 shares of
the Common Stock, which is 7.5% of the outstanding Common Stock.  As the
sole general partner of Blum L.P., RCBA Inc. is deemed the beneficial owner
of the securities over which Blum L.P. 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) Since the most recent filing of Schedule 13D, the Reporting Persons
purchased the following shares of Common Stock in the open market:
