EXPLANATORY NOTE

This Amendment No. 17 to Schedule 13D (this “Amendment No. 17”) is being filed with respect to the beneficial ownership of common stock, par value $0.001 per share (the “Common Stock”), of MedPro Safety Products, Inc., a Delaware corporation (the “Company” or the “Issuer”). This Amendment No. 17 supplements Items 2 and 4, and amends and restates in its entirety Item 5, of the Schedule 13D originally filed on August 13, 2010 (as amended to date).

ITEM 2. Identity and Background

Andrew Merkatz, United States Citizen (“Mr. Merkatz”), hereby resigns as a member of the Board of Directors. Mr. Merkatz’s principal occupation is serving as a Managing Director of the Investment Manager. During the last five years, Mr. Merkatz has not been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) 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.

ITEM 4. Purpose of Transaction.

On December 12, 2013 Mr. Merkatz resigned from the Board of Directors.

ITEM 5. Interest in Securities of the Issuer.

(a) As of December 20, 2013 (the date of filing of this Schedule 13D/A), the Master Fund and VCAF, collectively, (i) own 23,630,016 shares of Common Stock, (ii) have the ability to acquire an additional 8,985,243 shares of Common Stock through the exercise or conversion of derivative securities and (iii) thus beneficially own 32,615,259 shares of Common Stock, representing 74.9% of all of the Issuer’s outstanding Common Stock. The Investment Manager and Mr. Benowitz (and the General Partner with respect to the shares of Common Stock owned by VCAF) may each be deemed to beneficially own the shares of Common Stock beneficially owned by the Master Fund and VCAF. Each disclaims beneficial ownership of such shares.

As of December 20, 2013 (the date of filing of this Schedule 13D/A), Mr. Kleidman has the ability to acquire 100,000 shares of Common Stock through the exercise or conversion of derivative securities and thus beneficially owns 100,000 shares of Common Stock, representing 0.3% of all of the Issuer’s outstanding Common Stock.

As of December 20, 2013 (the date of filing of this Schedule 13D/A), Mr. Merkatz does not beneficially own any shares of Common Stock.

The foregoing is based on 34,540,878 shares of Common Stock outstanding as of August 8, 2013, as reported on the Issuer’s Form 10-Q for the fiscal quarter ended June 30, 2013, filed with the SEC on August 9, 2013.

(b) The Reporting Persons (other than Messrs. Kleidman and Merkatz) have shared power (with each other and not with any third party), to vote or direct the vote of and to dispose or direct the disposition of the 32,615,259 shares of Common Stock reported herein.

Mr. Kleidman has sole power to vote or direct the vote of and to dispose or direct the disposition of the 100,000 shares of Common Stock reported herein.

(c) Other than as described in Item 4 (as supplemented by this Amendment No. 16), no transactions in the Common Stock have been effected by the Reporting Persons in the last sixty (60) days.

(d) Not applicable.

(e) Not applicable.

SIGNATURE

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
