The following constitutes Amendment No. 6 (“Amendment No. 6”) to the Schedule 13D filed by the undersigned. This Amendment No. 6 amends the Schedule 13D as specifically set forth.

Item 3.

Source and Amount of Funds or Other Consideration

Item 3 is hereby amended and restated as follows:

As of the filing date of this Amendment No. 6, NP had invested $7,374,068 (inclusive of brokerage commissions) in shares of Common Stock of the Issuer. The source of these funds was the working capital of NP. Neither NCG nor NCM directly owns any shares of Common Stock.

As of the filing date of this Amendment No. 6, Mr. Schwarz directly owned 4,802 shares of Common Stock of the Issuer, currently exercisable options to acquire 7,700 shares of Common Stock of the Issuer and vested units of restricted stock exercisable into 6,071 shares of Common Stock of the Issuer, which shares, options and units were granted to him as consideration for his services as a director of the Issuer.

Item 4.

Purpose of Transaction

Item 4 is hereby amended and restated as follows:

The Reporting Persons purchased the shares of Common Stock based on the belief that the Common Stock, when purchased, was undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities, the availability of shares of Common Stock at desirable prices and other considerations, the Reporting Persons may endeavor to increase their position in the Company through, among other things, the purchase of shares of Common Stock in open market or private transactions, on such terms and at such times as the Reporting Persons deem advisable. The Reporting Persons may also determine to distribute shares of Common Stock of the Issuer to individuals or entities holding, directly or indirectly, partnership interests in NP.

Depending on various factors, the Reporting Persons may take such actions as they deem appropriate including, without limitation, engaging in discussions with management and the Board of Directors of the Company, including with respect to the existing operations and future plans of the Company, communicating with other shareholders, seeking additional board representation, making proposals to the Company concerning the capitalization and operations of the Company, purchasing additional shares of Common Stock, selling some or all of their shares of Common Stock, engaging in short selling of or hedging or similar transactions with respect to their shares of Common Stock or changing their intention with respect to any and all matters referred to in this Item 4.

Except as set forth herein or such as would occur upon completion of any of the actions discussed above, no Reporting Person has any present plan or proposal which 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

Item 5(a) is hereby amended and restated as follows:

(a) The aggregate percentage of shares of Common Stock reported to be owned by the Reporting Persons is based upon 5,743,186 shares, which is the total number of shares of Common Stock outstanding as of October 30, 2008, as reported in the Issuer’s Report on Form 10-Q filed with the Securities and Exchange Commission on November 6, 2008.

CUSIP NO. 631226107

As of the filing date of this Amendment No. 6, NP beneficially owned 993,905 shares of Common Stock, representing approximately 17.3% of the issued and outstanding Common Stock of the Issuer.

NCM, as the general partner of NP, may also be deemed to beneficially own the 993,905 shares of Common Stock beneficially owned by NP.

NCG, as the general partner of NCM, which in turn is the general partner of NP, may also be deemed to beneficially own the 993,905 shares of Common Stock beneficially owned by NP.

Mark E. Schwarz, as the managing member of NCG, the general partner of NCM, which in turn is the general partner of NP, may also be deemed to beneficially own the 993,905 shares of Common Stock beneficially owned by NP. In addition, as of the filing date of this Amendment No. 6, Mr. Schwarz directly owns 4,802 shares of Common Stock of the Issuer, currently exercisable options to acquire 7,700 shares of Common Stock of the Issuer and vested units of restricted stock exercisable into 6,071 shares of Common Stock of the Issuer, which, together with the Common Stock owned by NP, represents approximately 17.6% of the issued and outstanding Common Stock.
