Item 2.   Identity and Background

shares of Common Stock directly beneficially owned by S.A.C. Capital Associates,
LLC ("SAC Capital Associates");

directly beneficially owned by it; and

     (iv) Steven A. Cohen with respect to shares of Common Stock beneficially
owned by SAC Capital Advisors, SAC Capital Management and SAC Capital Associates
(collectively, together with Mr. Cohen, the "Reporting Persons").

     The Reporting Persons expressly disclaim beneficial ownership of securities
directly beneficially owned by any person or entity other than, to the extent of
any pecuniary interest therein, the various accounts under the Reporting
Persons' management and control.

 (b) The address of the principal business office of (i) SAC Capital Advisors
and Mr. Cohen is 72 Cummings Point Road, Stamford, Connecticut 06902, (ii) SAC
Capital Management is 540 Madison Avenue, New York, New York 10022, and (iii)
SAC Capital Associates is P.O. Box 58, Victoria House, The Valley, Anguilla,
British West Indies.

 (c) The principal business of SAC Capital Associates is to serve as a private
investment limited liability company. The principal business of each of SAC
Capital Advisors and SAC Capital Management is to serve as investment manager to
a variety of private investment funds, including SAC Capital Associates, and to
control the investing and trading in securities by these private investment
funds. The principal business of Mr. Cohen is to serve as a principal of SAC
Capital Advisors, SAC Capital Management and other affiliated entities.




 (d) None of the Reporting Persons has, during the last five years, been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors).

 (e) None of the Reporting Persons has, during the last five years, 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.

 (f) SAC Capital Advisors and SAC Capital Management are Delaware limited
liability companies. SAC Capital Associates is an Anguillan limited liability
company. Mr. Cohen is a United States citizen.

Item 3.   Source and Amount of Funds or Other Consideration.

     SAC Capital Associates expended an aggregate of approximately
$30,339,902.92 of its investment capital to purchase the 1,905,806 shares of
Common Stock. Such shares were effected in open market purchases and acquired in
the ordinary course of business, and are held by SAC Capital Associates in a
commingled margin account maintained at Goldman Sachs & Co., which may extend
margin credit to the Reporting Persons as and when required to open or carry
positions in the margin account, subject to applicable federal margin
regulations, stock exchange rules and credit policies. In such instances, the
positions held in the margin account are pledged as collateral security for the
repayment of debit balances in the account. The margin account may from time to
time have debit balances. Since other securities are held in the margin account,
it is not possible to determine the amounts, if any, of margin used to purchase
the shares of Common Stock reported herein.

Item 4.   Purpose of Transaction.

     SAC Capital Associates originally acquired the Common Stock reported herein
for investment purposes, in the ordinary course of business, and not with the
purpose or with the effect of changing or influencing the control or management
of the Issuer and without any agreement with any third party to act together for
the purpose of acquiring, holding, voting or disposing of equity securities of
the Issuer.

     The Reporting Persons believe that the Issuer's assets, including
intellectual property, tax attributes and ongoing operations, are undervalued
and are not appropriately reflected in the price of the Common Stock of Issuer.
The Reporting Persons believe that the best way for the Issuer to increase
shareholder value would be a public sale of the Issuer.

     As part of the Reporting Persons' continuing evaluation of, and
preservation of the value of their investment in the Common Stock of the Issuer,
the Reporting Persons may from time to time (i) engage in discussions with,
including, without limitation,




management or representatives, the Issuer's Board of Directors, other
shareholders of the Issuer and other relevant parties concerning matters with
respect to the Reporting Persons' investment in the Common Stock, including,
without limitation, the business, operations, governance, management,
composition of the Issuer's Board of Directors, strategy and future plans of the
Issuer, (ii) write letters to, and respond to inquiries from, various parties,
including without limitation, the Issuer's Board of Directors, management or
representatives, other shareholders and other persons or entities regarding the
Issuer's affairs and strategic alternatives.

     Depending on various factors, including, the Issuer's financial position
and strategic direction, the outcome of any discussions referenced above,
actions taken by the Issuer's Board of Directors, price levels of the Common
Stock, other investment opportunities available to the Reporting Persons,
conditions in the securities market and general economic and industry
conditions, the Reporting Persons may in the future take such actions with
respect to their investment in the Issuer as they deem appropriate with respect
to any or all matters referred to in this Item 4 of Schedule 13D. The Reporting
Persons may, from time to time, acquire or cause an affiliate to acquire
additional Common Stock or dispose or cause an affiliate to dispose of some or
all of their Common Stock, engage in short-selling or hedging or similar
transactions with some or all of their Common Stock, or may continue to hold the
Common Stock, depending on business and market conditions, their continuing
evaluation of the business and prospects of the Issuer, general investment and
trading policies of the Reporting Persons, and other factors, including changing
their intention with respect to any or all matters referred to in this Item 4 of
Schedule 13D. Except as set forth herein, or as would occur upon completion of
any of the matters discussed herein, the Reporting Persons have no present plan
or proposal that would relate to or result in any of the matters set forth in
subparagraphs (a)-(j) of Item 4 of Schedule 13D.

Item 5.   Interest in Securities of the Issuer.

 (a) As of the close of business on October 2, 2007, the Reporting Persons
beneficially own an aggregate of 1,905,806 shares of Common Stock, representing
approximately 8.9% of the shares of Common Stock outstanding. The percentages
used herein are based upon the 21,308,220 shares of Common Stock reported to be
outstanding as of August 1, 2007 by the Issuer in its Quarterly Report on Form
10-Q filed with the Securities and Exchange Commission on August 9, 2007.

     SAC Capital Advisors, SAC Capital Management and Mr. Cohen own directly no
shares of Common Stock. Pursuant to investment management agreements, each of
SAC Capital Advisors and SAC Capital Management share all investment and voting
power with respect to securities held by SAC Capital Associates. Mr. Cohen,
through one or more intermediary holding companies, controls each of SAC Capital
Advisors and SAC Capital Management. By reason of the provisions of Rule 13d-3
of the Act, as amended, each of SAC Capital Advisors, SAC Capital Management and
Mr. Cohen may be deemed to own beneficially 1,905,806 shares of Common Stock
(constituting approximately 8.9% of the shares of Common Stock outstanding).




 (b) None of the Reporting Persons has sole power to vote or direct the vote
or sole power to dispose or direct the disposition of shares of Common Stock.

     (i) SAC Capital Advisors has shared power to vote or direct the vote and
shared power to dispose or direct the disposition of 1,905,806 shares of Common
Stock, constituting approximately 8.9% of such class of securities;

     (ii) SAC Capital Management has shared power to vote or direct the vote and
shared power to dispose or direct the disposition of 1,905,806 shares of Common
Stock, constituting approximately 8.9% of such class of securities;

     (iii) SAC Capital Associates has shared power to vote or direct the vote
and shared power to dispose or direct the disposition of 1,905,806 shares of
Common Stock, constituting approximately 8.9% of such class of securities; and

     (iv) Steven A. Cohen has shared power to vote or direct the vote and shared
power to dispose or direct the disposition of 1,905,806 shares of Common Stock,
constituting approximately 8.9% of such class of securities.

 (c) Information concerning transactions in the shares of Common Stock
effected by the Reporting Persons during the past 60 days is set forth in
Schedule A hereto and is incorporated herein by reference. All of such
transactions were effected in open market purchases through various brokerage
entities on the NASDAQ.

 (d) No person other than SAC Capital Associates, SAC Capital Advisors, SAC
Capital Management and Steven A. Cohen is known to have the right to receive or
the power to direct the receipt of dividends from, or the proceeds from the sale
of, the shares of Common Stock directly beneficially owned by SAC Capital

 (e) Not applicable.

Item 6.   Contracts, Arrangements, Understandings or Relationships with Respect
          to Securities of the Issuer.

     On August 17, 2007, a call option held by SAC Capital Associates with
respect to 100,000 shares of Common Stock, with an exercise price of $17.50,
expired.

     Other than as described herein, there are no contracts, arrangements,
understandings or relationships (legal or otherwise) between the Reporting
Persons and any other person with respect to the securities of the Issuer.

     The Reporting Persons may, from time to time, enter into and dispose of
cash-settled equity swaps or other similar derivative transactions with one or
more counterparties that are based upon the value of shares of Common Stock,
which transactions may be significant in amount. The profit, loss and/or return
on such




contracts may be wholly or partially dependent on the market value of the shares
of Common Stock, the relative value of shares of Common Stock in comparison to
one or more other financial instruments, indexes or securities, a basket or
group of securities in which shares of Common Stock may be included, or a
combination of any of the foregoing. These contracts do not give the Reporting
Persons direct or indirect voting, investment or dispositive control over any
securities of the Issuer and do not require the counterparties thereto to
acquire, hold, vote or dispose of any securities of the Issuer. As of the date
hereof, an affiliate of the Reporting Persons, S.A.C. MultiQuant Fund, LLC,
currently has short economic exposure to 1,000 shares of Common Stock and 29,548
shares of Common Stock on loan from a third party to cover an open short
position in the same number of shares. Accordingly, the Reporting Persons
disclaim any beneficial ownership in any securities that may be referenced in
such contracts or that may be held from time to time by any counterparties to
such contracts.
