The shares of common stock were acquired pursuant to a cashless exercise mechanism in Warrant No. 2008-3 and Warrant No. 2008-18 held by Focus Fund, and pursuant to a cashless exercise mechanism in Warrant No. 0007 held by Hughes Capital.

In connection with Focus Fund’s election of a cashless exercise of Warrant No. 2008-3 on September 12, 2012 for the purchase of 1,400,004 shares of common stock at a exercise price of $0.18 and a conversion price of $0.0865 per share, 945,594 warrant shares were tendered to the Issuer as consideration for the warrant exercise, resulting in a net issuance of 454,410 shares of common stock after the cashless exercise of such warrant.

In connection with Hughes Capital’s election of a cashless exercise of Warrant No. 0007 on September 12, 2012 for the purchase of 240,000 shares of common stock at a exercise price of $0.25 and a conversion price of $0.0164 per share, 225,225 warrant shares were tendered to the Issuer as consideration for the warrant exercise, resulting in a net issuance of 14,775 shares of common stock after the cashless exercise of such warrant.

The Reporting Persons acquired the shares of common stock for general investment purposes.

Item 4. Purpose of Transaction.

The securities referred to in this Schedule have been acquired for investment purposes and not with the purpose or effect of changing or influencing control of the Issuer. Focus Fund and Hughes Capital acquired the securities in the ordinary course of business and each is holding the securities for the benefit of its investors. The Reporting Persons evaluate their respective investments in the shares on a continual basis. Focus Fund’s exercises of the warrants were made prior to the warrants’ January 3, 2013 expiration, and Hughes Capital’s exercise of the warrant was made prior to the warrant’s May 10, 2016 expiration.

In addition to the actions described above, the Reporting Person may also pursue other alternatives available in order to maximize the value of its investments in the Issuer. Such alternatives could include, without limitation: (a) the purchase of additional common stock in the open market, in privately negotiated transactions or otherwise, and (b) the sale of all or a portion of the common stock now owned or hereafter acquired by the Reporting Persons.

Except as otherwise set forth in this Schedule, including but not limited to the information set forth in Item 6 regarding the Tender and Voting Agreement, the Reporting Persons have no present plans or proposals which relate to or would result in: (a) the acquisition of additional securities of the Issuer or the disposition of securities of the Issuer; (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer; (c) a sale or transfer of a material amount of assets of the Issuer; (d) a change in the present Board of Directors or management of the Issuer; (e) any material change in the present capitalization or dividend policy of the Issuer; (f) any other material change in the Issuer’s business or corporate structure; (g) changes in the Issuer’s charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) causing a class of equity securities of the Issuer to become eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or (j) any action similar to any of those enumerated above.

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

Tender and Voting Agreement

On August 13, 2012, the Issuer entered into an agreement and plan of merger (the “Merger Agreement”) with CONMED Corporation, a New York corporation (“Parent”), and Arrow Merger Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent (“Purchaser”) pursuant to which Purchaser will commence a tender offer (the “Offer”) to purchase all of the outstanding shares of the Issuer’s common stock, par value $0.001 per share at a price of $0.27 per share of common stock in cash, net to the seller but subject to any required withholding taxes applicable to the seller (the “Offer Price”) upon the terms and subject to the conditions set forth in the Offer and the Merger Agreement. After the closing of the Offer, and subject to the satisfaction or waiver of certain conditions, Purchaser will merge with and into the Issuer, with the Issuer surviving the Merger as a wholly-owned subsidiary of Parent.

On August 13, 2012, as a condition and inducement to Parent’s and Purchaser’s willingness to enter into the Merger Agreement, certain holders of shares of the Issuer, including Hughes Capital as the general partner of Focus Fund, entered into tender and voting agreements with Parent and Purchaser (the “Tender and Voting Agreement”), whereby each such holder, including Hughes Capital as the general partner of Focus Fund, agreed to tender into the Offer all of the shares of common stock of the Issuer that it beneficially owns and, if necessary, vote such shares of common stock in favor of the Merger Agreement at any stockholders’ meeting called for that purpose.

Pursuant to the Tender and Voting Agreement, Hughes Capital as the general partner of Focus Fund has irrevocably appointed Parent as proxy and attorney-in-fact (with full power of substitution) to vote the respective shares as to which Hughes Capital as the general partner of Focus Fund has voting power and in its name, place and stead, at any meeting of the stockholders of the Issuer, however called, and in any action by written consent of stockholders of the Issuer in a manner consistent with the Tender and Voting Agreement. Additionally, Hughes Capital as the general partner of Focus Fund has agreed to promptly (and, in any event, no later than the tenth business day following the commencement of the Offer) validly tender or cause to be validly tendered in the Offer, pursuant to and in accordance with the terms of the Offer and Rule 14d-2 under the Act, all of the shares owned by Hughes Capital as the general partner of Focus Fund on or prior to the tenth business day following the commencement of the Offer.

Shared dispositive power with respect to the 4,965,269 shares of common stock controlled as of record by Hughes Capital as the general partner of Focus Fund may be deemed to have been acquired through execution of the Tender and Voting Agreement.

A copy of the Merger Agreement is attached as Exhibit 1 to this Schedule. A copy of the Tender and Voting Agreement is attached as Exhibit 2 to this Schedule. References to, and descriptions of, the Merger Agreement and the Tender and Voting Agreement as set forth above in this Item 6 are qualified in their entirety by reference to the copy of the Merger Agreement and the copy of Tender and Voting Agreement included as Exhibit 1 and Exhibit 2, respectively, to this Schedule and which are incorporated herein in their entirety by this reference.
