The Issuer filed the registration statement required by the 2008 RRA on April 11, 2008 and it was declared effective by the Commission on November 10, 2008.

March 2015 Warrant Exercises

On March 20, 2015, LVP and LCA fully exercised the Secondary Warrants. Such exercises were effected on a “cashless” basis, pursuant to which certain of the shares of Common Stock issuable upon exercise of the Secondary Warrants were withheld by the Issuer as payment of the exercise price, based on the closing price per share of the Common Stock on March 19, 2015, which was $5.85 per share. As a result, (i) upon LVP’s full exercise of its Secondary Warrants to purchase 486,443 shares of Common Stock, the Issuer withheld 230,333 of such shares to pay the exercise price, issued to LVP the remaining 256,110 shares, paid to LVP $0.94 in cash in lieu of a fractional share and cancelled the Secondary Warrants in full, and (ii) upon LCA’s full exercise of its Secondary Warrants to purchase 9,750 shares of Common Stock, the Issuer withheld 4,617 of such shares to pay the exercise price, issued to LCA the remaining 5,133 shares, paid to LCA $1.95 in cash in lieu of a fractional share and cancelled the Secondary Warrants in full. No funds or other consideration were used by LVP or LCA in connection with such exercises of the Secondary Warrants.

On March 20, 2015 and March 24, 2015, LVP fully exercised the Original Warrants. Such exercises were effected on a “cashless” basis, pursuant to which certain of the shares of Common Stock issuable upon exercise of the Original Warrants were withheld by the Issuer as payment of the exercise price, based on the closing price per share of the Common Stock on March 19, 2015, which was $5.85 per share, and on March 23, 2015, which was $5.65 per share. As a result, (i) upon LVP’s exercise of the Original Warrants to purchase 634,516 shares of Common Stock on March 20, 2015, the Issuer withheld 300,447 of such shares to pay the exercise price, issued to LVP the remaining 334,069 shares and paid to LVP $5.63 in cash in lieu of a fractional share, and (ii) upon LVP’s exercise of all of the remaining 1,130,709 shares of Common Stock subject to the Original Warrants on March 24, 2015, the Issuer withheld 554,348 of such shares to pay the exercise price, issued to LVP the remaining 576,361 shares, paid to LVP $2.27 in cash in lieu of a fractional share and cancelled the Original Warrants in full.

As a result, on March 30, 2015 (i) LVP used $3,401,235 of investment funds provided to LVP by its investors to purchase 839,811 shares of Common Stock and its 2012 Warrants were cancelled in full, and (ii) LCA used $68,174 of investment funds provided to LCA by its investors to purchase 16,833 shares of Common Stock and its 2012 Warrants were cancelled in full.

These stock options were granted at various dates and have various exercise prices and vesting schedules. All of the shares underlying these stock options are currently exercisable or exercisable within 60 days after March 20, 2015.

Item 4.

Purpose of Transaction.

Item 4 of the Schedule is amended and restated in its entirety to read as follows:

The purpose of the acquisition of all of the shares of Common Stock and the Warrants by the Reporting Persons is general investment purposes. In addition, the Reporting Persons may, from time to time, depending on prevailing market, economic and other conditions, acquire additional shares of Common Stock or other securities of the Issuer or engage in discussions with the Issuer concerning further acquisitions of shares of Common Stock or other securities of the Issuer or further investments in the Issuer. The Reporting Persons intend to review their investment in the Issuer on a continuing basis and, depending upon the price and availability of shares of Common Stock, subsequent developments affecting the Issuer, the Issuer’s business and prospects, other investment and business opportunities available to the Reporting Person, general stock market and economic conditions, tax considerations and other factors considered relevant, may decide at any time to increase or to decrease the size of their investment in the Issuer.

On each of December 10, 2012 and November 21, 2013, LVP adopted a Rule 10b5-1 trading plan (collectively, the “Trading Plans”). The Trading Plans were established as part of LVP’s investment strategy for asset diversification and liquidity over time. Each Trading Plan was adopted during an “open window” in accordance with guidelines specified by Rule 10b5-1 under the Act and as permitted by the Issuer’s insider trading policy. Each Trading Plan established predetermined trading parameters that, among other things, did not permit the party that adopted the Trading Plans to exercise subsequent influence over how, when or whether to effect sales thereunder.

Page 11 of 14 Pages

Up to 3,000,000 shares of Common Stock could be sold under each of the Trading Plans.

(a) According to the Annual Report on Form 10-K filed by the Issuer with the Commission on March 13, 2015, as of March 2, 2015, there were 101,405,250 shares of Common Stock outstanding. LVP is the record holder of 14,516,932 shares of Common Stock, representing approximately 14.3% of the issued and outstanding shares of Common Stock. LCA is the record holder of 194,958 shares of Common Stock, representing approximately 0.2% of the issued and outstanding shares of Common Stock. LVP and LCA may reallocate their holdings of securities among themselves and may be deemed to beneficially own securities on an aggregated basis. LCP, as general partner of each of LVP and LCA, has the power to vote and dispose of securities held by each of them. Mr. Enright and Ms. Bakker are the managing members of LCP and share the decision-making power of LCP with respect to the Issuer’s securities. Mr. Enright also holds stock options to purchase up to 250,000 shares of Common Stock, all of which are currently exercisable or exercisable within 60 days after March 20, 2015. Mr. Enright shares pecuniary interest in the shares underlying such stock options with the other Reporting Persons pursuant to a contractual relationship, and Mr. Enright may, at his election, confer with the other Reporting Persons prior to making any decisions relating to the voting or disposition of such stock options or the shares issuable upon exercise of such stock options.

(b) LVP, LCA and LCP have shared power to vote and dispose of 14,711,890 shares of Common Stock. Mr. Enright and Ms. Bakker, managing directors of LCP, may be deemed to have shared voting and dispositive power with respect to all such shares. Mr. Enright holds sole dispositive and voting power with respect to 250,000 shares of Common Stock underlying stock options that are currently exercisable or exercisable within 60 days after March 20, 2015, which were issued to Mr. Enright as consideration for his service as a director on the Board.

(c) Except as reported herein, no Reporting Person has effected any transactions in the Issuer’s securities within the past 60 days.

(d) Not applicable.

(e) Not applicable.

Item 6.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Item 6 of the Schedule is amended and restated in its entirety to read as follows:

In accordance with the terms of the 2008 Purchase Agreement, the Issuer has agreed to take all necessary acts to have one designee of LVP nominated for election to the Board, subject to compliance with relevant NASDAQ rules and regulations and subject to the approval of such nominee by the Nominating and Corporate Governance Committee of the Board. This obligation shall terminate if at any time LVP beneficially owns less than 5% of the Issuer’s issued and outstanding Common Stock (including shares of Common Stock issuable upon exercise of warrants), and in such case, the Board member nominated by LVP shall resign from the Board. In accordance with this obligation, the Issuer appointed Mr. Enright to the Board as of the closing of the offering contemplated by the 2008 Purchase Agreement. The Issuer also agreed to maintain directors’ and officers’ liability insurance in an amount reasonably acceptable to LVP to the extent such coverage is available on terms that are commercially acceptable to the Board and consistent with industry practice.

The Issuer has registered the shares of Common Stock acquired by LVP and LCA pursuant to the 2008 Purchase Agreement, the 2009 Purchase Agreement, the 2010 WPA and the 2012 WPA (including the shares subject to the Warrants) for resale under the Securities Act of 1933, as amended.
