(the "Company"). The principal executive offices of the Company are located at 420 Lexington Avenue, Suite 450, New York, NY 10170.

On July 9, 2007, the Board of Directors approved a one-for-ten reverse stock split to be effective upon the initial closing of a public offering of the Company's securities in order to satisfy the listing requirements of the American Stock Exchange. On August 9, 2007 the reverse split was effective and the Company's Common Stock commenced trading on The American Stock Exchange under the symbol "NBS." Item 2.

On December 5, 2006, the Compensation Committee of the Company's Board of Directors approved a grant to Mr. Weinreb of options to purchase up to 10,000 shares of Common Stock at an exercise price of $6.00 per share, pursuant to the Company's 2003 Equity Participation Plan (the "Plan"), to vest upon the achievement of certain business milestones. In connection with Mr. Weinreb's entering into a supplement to his employment agreement effective January 26, 2007, the vesting of such options was accelerated and they became vested in their entirety on such date. On September 27, 2007 (as later amended on November 12, 2007), the Compensation Committee of the Company's Board of Directors approved the following grants to Mr. Weinreb: (i) 30,000 shares of restricted stock pursuant to the Plan, in his capacity as a member of the Board of Directors, 15,000 of which are scheduled to vest on April 1, 2008 and 15,000 of which are scheduled to vest on September 27, 2008 subject to Mr. Weinreb's continued service; (ii) 10,000 shares of restricted stock pursuant to the Plan, 5,000 of which are scheduled to vest on April 1, 2008 and 5,000 of which are scheduled to vest on September 27, 2008, subject to Mr. Weinreb's continued employment; (iii) options to purchase 10,000 shares of Common Stock pursuant to the Plan, which vested immediately; and (iv) options to purchase 40,000 shares of Common Stock pursuant to the Plan, that vest upon the achievement of certain business milestones. On October 2, 2007 and October 12, 2007, respectively, two of these business milestones were achieved and options to purchase 15,000 and 15,000 shares of Common Stock, respectively, vested on such dates. Item 4. Purpose of Transaction The securities described in Item 3 were granted to Mr. Weinreb as compensation for services. Mr. Weinreb does not have any present plans or proposals which relate to or would result in the types of events described in clauses (a) through (j) under Item 4 of Schedule 13D. Item 5. Interest in Securities of the Issuer Item 5 of this Schedule 13D is amended by deleting the entirety of the text and replacing it with the following: As of September 27, 2007, there were 4,300,668 shares of Common Stock outstanding. As of such date, Mr. Weinreb was the beneficial owner of an aggregate of 213,423 shares of Common Stock, or 4.8% of the outstanding shares of Common Stock. This number includes options to purchase up to 120,500 shares of Common Stock (inclusive of options to purchase an aggregate of 30,000 shares of Common Stock which vested pursuant to the achievement of certain business milestones in October 2007, as noted in Item 3 hereof), which are exercisable within sixty days of this Schedule 13D. Mr. Weinreb has the sole power to vote or to direct the vote and the sole power to dispose or to direct the disposition of all of such shares. Although the issuances of securities described in Item 3 caused Mr. Weinreb's beneficial ownership of the Common Stock to increase by more than 1% as of September 27, 2007, Mr. Weinreb ceased to be the beneficial owner of more than five percent of the Common Stock of the Company due to the increase in the number of shares of Common Stock outstanding as a result of the initial closing of the Company's public offering of securities on August 8, 2007. Except as described in Item 3 of this Amendment, during the past sixty days, there were no purchases of shares of Common Stock, or securities convertible into or exchangeable for shares of Common Stock, by Mr. Weinreb or any person or entity controlled by Mr. Weinreb or any person or entity for which Mr. Weinreb possesses voting control over the securities thereof. During such sixty day period, there were no sales of the shares of Common Stock, or securities convertible into or exchangeable for shares of Common Stock, by Mr. Weinreb or any person or entity controlled by Mr. Weinreb or any person or entity for which Mr. Weinreb possesses voting control over the securities thereof. -4-
