         Item 3 is hereby amended by adding thereto the following:

         The Aryeh Entities expended an aggregate of approximately $6,346,859.25
of its own investment capital to acquire the 1,232,650 shares of Common Stock
held by it. All Shares were acquired in open market purchases on the Nasdaq
National Market.

ITEM 4. PURPOSE OF TRANSACTION.

         Item 4 of the Schedule 13D is hereby amended by adding thereto the
following:

         As previously announced, the Third Point Reporting Persons plan to
conduct shortly a consent solicitation to remove Thomas H. McLain ("Mr. McLain")
and other directors from the Board of Directors (the "Board"). In the
solicitation, the Reporting Persons will seek stockholder support to replace a
majority of the directors of the Company with persons nominated by the Third
Point Reporting Persons in order to provide new leadership for the Company with
the goal of maximizing stockholder value under the leadership of a new chief
executive officer. In conjunction with this solicitation, the Third Point
Reporting Persons intend to file a consent statement with the Securities and
Exchange Commission (the "SEC"), in which the Third Point Reporting Persons will
nominate Mr. Aryeh, Todd Davis, Stephen Kasnet, Timothy Lynch and Stuart Oran to
be appointed by the remaining members of the Board to fill any vacancies created
by the removal of directors.

         Pursuant to the Company's Bylaws, any stockholder of record seeking to
have the stockholders authorize or take a corporate action by written consent
must request, by written notice, that the Board fix a record date to establish
those stockholders that are entitled to give their consent. The Company's Board
must promptly, but in all events within 10 days after the date the request is
received, adopt a resolution fixing the record date for the solicitation, which
record date must be no more than 10 days after the date of the resolution. The
Third Point Reporting Persons intend in the future to deliver to the Company
such a written notice in order to seek corporate action by written consent.
However, neither this filing nor the filing of a consent statement, whether in
preliminary or definitive form, with the SEC shall be deemed a request by the
Reporting Persons or any other Company stockholder for the Board to set a record
date for the consent solicitation.




         On October 26, 2006, Mr. Aryeh contacted Mr. McLain to clarify
fundamental issues regarding NABI-HB raised on the Company's earnings conference
call held the prior day. Mr. Aryeh also advised Mr. McLain that he had agreed to
be a nominee of the Third Point Reporting Persons, and that he regretted that
the Company's dispute with many of its largest stockholders had come to such an
impasse. Later that day, Mr. McLain reached out to Mr. Aryeh and proposed that
Mr. Aryeh act as an intermediary to attempt to reach a settlement with the Third
Point Reporting Persons. With the consent of the Third Point Reporting Persons,
Mr. Aryeh again proposed a settlement offer substantially on the terms
previously proposed on September 29, 2006. Discussions continued on October 27,
2006 and ended without an agreement because the parties could not agree on the
composition of the strategic action committee (the "SAC"). The Company insisted
that the SAC be a committee of five members, consisting of three current Board
members and two of the Third Point Reporting Persons' nominees, and the
Reporting Persons agreed that the SAC could be a committee of five members if
there were a mutual agreement on the fifth member. The Reporting Persons
proposed that the SAC be established with four members - two designated by the
Board and two of the Management Company's nominees - and that the four members,
by majority vote, would choose a fifth member from among the current Board
members and, failing agreement in good faith, that the four members would seek
to agree in good faith on an independent person not currently on the Board to be
added to the Board and the SAC. The discussions ended because the Company
required that the fifth member of the SAC be another current member of the
Board. Subsequently, on October 30, 2006, the Reporting Persons and the Company
renewed discussions, but no settlement has been reached and significant
differences between their respective positions remain.

                                     * * * *

         In connection with the consent solicitation, Third Point LLC and
certain of its affiliates intend to file a consent statement with the SEC to
solicit stockholders of the Company with respect to the removal of a majority of
the Board of Directors. THIRD POINT LLC STRONGLY ADVISES ALL STOCKHOLDERS OF THE
COMPANY TO READ THE CONSENT STATEMENT WHEN IT BECOMES AVAILABLE BECAUSE IT WILL
CONTAIN IMPORTANT INFORMATION, INCLUDING INFORMATION RELATING TO THE
PARTICIPANTS IN ANY SUCH CONSENT SOLICITATION. SUCH CONSENT STATEMENT, WHEN
FILED, AND ANY OTHER RELEVANT DOCUMENTS WILL BE AVAILABLE AT NO CHARGE ON THE
SEC'S WEBSITE AT HTTP://WWW.SEC.GOV.
