Explanatory Note

 

The Reporting Persons (as defined below) previously filed statements of beneficial ownership on Schedule 13G pursuant to Rule 13d-1(d) (see Schedule 13G filed with the Securities and Exchange Commission on February 14, 2006, as last amended by filing a Schedule 13G/A with the Securities and Exchange Commission on February 15, 2008). On December 31, 2009, as described below, certain affiliates of Sanderling Venture Partners acquired 1,012,130 shares of common stock of the Issuer (as defined below) which, when combined with all other purchases by affiliates of Sanderling Venture Partners within the previous 12 months, exceeded 2% of the outstanding common stock of the Issuer (see Item 5). As a result, the Reporting Persons are filing this Schedule 13D. Additionally, on February 24, 2009, certain affiliates of Sanderling Venture Partners acquired warrants to purchase 791,140 shares of common stock of the Issuer. The Reporting Persons expressly disclaim status as a “group” for purposes of this Schedule 13D.

Item 3.

Source and Amount of Funds or Other Consideration.

 

Pursuant to the terms of that certain Securities Purchase Agreement, dated December 29, 2008, by and between VI Co-Investment, VI LP, VI GmbH, VI Management (collectively, the “Sanderling Purchasers”), Alafi Capital Company, LLC (“Alafi Capital”) and the Issuer (the “Securities Purchase Agreement”), the Sanderling Purchasers purchased an aggregate of 1,012,130 Shares and warrants to purchase 2,429,752 Shares on December 31, 2008, at a price of $4.94 per unit (representing the closing bid price of the Shares on the trading day preceding the execution of the Securities Purchase Agreement, plus an additional $0.125 per Share underlying the Warrants). The units were purchased by the Sanderling Purchasers with working capital. The Warrants are exercisable at $4.64 per Share, are exercisable on or after the date immediately following the six month anniversary of their issuance and have a five year term from that initial exercisability date. In addition, the Warrants will be exercisable on a cashless basis (by surrender of the number of Shares underlying the Warrants having a fair market value equal to the aggregate exercise price of the Shares being acquired) until and including the expiration date. The applicable per Share purchase price and the number of Shares issuable upon exercise of the Warrants are subject to adjustment for the occurrence of certain events, including stock dividends and split-ups, combinations, reorganizations and reclassifications. The sale of the Shares and Warrants described above was part of a registered direct offering by the Issuer to the Sanderling Purchasers and Alafi Capital. The closing of the transaction occurred on December 31, 2008.

Pursuant to the terms of that certain First Amendment to Note and Warrant Purchase Agreement, effective as of December 28, 2008 (the “First Amendment”) which amended that certain Note and Warrant Purchase Agreement effective February 21, 2008, by and between the Issuer, VI Co-Investment, VI GmbH, VI LP (collectively, the “Sanderling Parties”) and Alafi Capital, the Sanderling Partners received warrants to purchase an aggregate of 791,140 Shares in consideration for their agreement to extend the Issuer up to an aggregate of $5 million on an unsecured basis through the earlier of March 31, 2010 or the date the Issuer receives at least $20 million of third party, non-bank financing. The warrants are exercisable at $3.16 per Share (representing the average closing price for the Shares on The NASDAQ Global Market for the five business days preceding February 24, 2009), are exercisable immediately upon issuance and have a five year term from the issuance date. In addition, the warrants are exercisable on a cashless basis (by surrender of the number of Shares underlying the warrants having a fair market value equal to the aggregate exercise price of the Shares being acquired) until and including the expiration date. The applicable per Share purchase price and the number of Shares issuable upon exercise of the warrants are subject to adjustment for the occurrence of certain events, including stock dividends and split-ups, combinations, reorganizations and reclassifications.

The Funds used by the Reporting Persons and General Partners that are entities to acquire the securities described herein were obtained from capital contributions by their partners and from direct capital commitments by such Reporting Persons and General Partners.

 

References to and descriptions of the transaction as set forth in this Item 3 are qualified in their entirety by reference to (a) the form of Securities Purchase Agreement and the form of warrant issued in connection therewith attached as Exhibits to the Issuer’s Current Report on Form 8-K, filed with the Securities and Exchange Commission on December 29, 2008, and (b) the form of warrant issued in connection with the First Amendment, filed herewith, which documents are incorporated by reference in their entirety in this Item 3.

In addition, depending upon the factors referred to above, the Reporting Persons or General Partners may dispose of all or a portion of their securities of the Issuer at any time. Each of the Reporting Persons and General Partners reserves the right to increase or decrease its holdings on such terms and at such times as each may decide.

 

The warrants issued pursuant to the Securities Purchase Agreement become exercisable in June 2009 and certain stock options held by Mr. Middleton vest in May 2009. Other than as described above in this Item 4, none of the Reporting Persons or General Partners have any plan or proposal relating to or that would result in: (a) the acquisition by any person 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 or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) any change in the Board of Directors or management of the Issuer, including any plans or proposals to change the number or terms of directors or to fill any existing vacancies on the Board of Directors 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

The aggregate percentage of Shares reported owned by each person named herein is based upon 41,802,297 Shares outstanding, which is the total number of Shares outstanding as reported in the Issuer’s Prospectus Supplement, filed with the Securities and Exchange Commission on December 30, 2008, giving effect to both of the Issuer’s offerings of Shares that closed on December 31, 2008, as described therein.

Item 6.

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

 

On February 21, 2008, VI Co-Investment, VI GmbH, VI LP and Alafi Capital Company, LLC (the “Lenders”), executed a $20 million unsecured loan commitment to the Issuer pursuant to a Note and Warrant Purchase Agreement (the “Note and Warrant Purchase Agreement”), which may take the form, at the Issuer’s option, of guarantees in favor of Silicon Valley Bank, the Issuer’s primary lender bank (the “Bank”), severally but not jointly and severally, of amounts borrowed by the Issuer from the Bank. On November 4, 2008, the Issuer and the Lenders executed a term sheet under which the Lenders committed to extend this agreement. As amended, the commitment will expire on the earlier of March 31, 2010 or the date the Issuer receives at least $20 million of third party, non-bank financing (a “Qualified Financing”). This facility may also be used by the Issuer to guarantee its loan commitments with the Bank through the same extended term. Under the agreement, the Issuer agreed to issue additional warrants to purchase common stock to the Lenders in exchange for the extension of the commitment. The number of warrants and exercise price were to be agreed upon at a later time. The Issuer agreed to use its best efforts to register the shares of common stock underlying the warrants.

The First Amendment, effective as of December 29, 2008, amended the Note and Warrant Purchase Agreement. Pursuant to the First Amendment, the Issuer had the option to extend the term the Note and Warrant Purchase Agreement originally executed through the earlier of March 31, 2010 or the date of a Qualified Financing. On February 24, 2009, the Issuer exercised the term extension. As a result, the Lenders received additional warrants to purchase Shares in consideration of such extension.

In December 2008, the Lenders and the Issuer agreed that, effective at closing of the Securities Purchase Agreement, the loan obligation would decrease from an aggregate of $20 million to $10 million. If exercised, the loan extension would only be for an aggregate of $10 million. The Lenders would receive additional warrant coverage equal to 50% of the $10 million extension amount upon the Issuer’s exercise of the extension of the facility. Such warrants would have a term of five years from the date of issuance and would be issued at the time the Issuer exercises the extension, with an exercise price equal to the average of the five-day closing sale price ending on the date prior to the exercise of the extension and issuance of the warrants, provided that the exercise price will not be lower than the closing bid price immediately preceding the time the Issuer exercises the extension right. The “Qualified Financing” definition was amended to exclude the proceeds from the offering pursuant to the securities purchase agreement entered into by the Issuer with certain investors at the same time as the Securities Purchase Agreement.
