Credit Facilities

In October 2009, the Company entered into a revolving credit facility with Wells Fargo Bank (“Wells”), which was last amended on February 20, 2012, whereby the Company may borrow up to $20.0 million, subject to the calculation and limitation of a borrowing base (“Wells Credit Facility”). All amounts owing under the Wells Credit Facility will become due and payable upon its expiration on March 31, 2013. As of June 30, 2012, the Company did not have any outstanding borrowings under the Wells Credit Facility. Any outstanding amounts under the Wells Credit Facility bear interest at a variable rate equal to the Wells prime rate, plus 1.00%, which is payable on a monthly basis. The Wells Credit Facility is collateralized by all of the Company's assets, except its intellectual property.

The Wells Credit Facility contains financial covenants requiring the Company to (i) maintain a minimum current ratio of 1.5, equal to the quotient of modified current assets to current liabilities, as defined in the Wells Credit Facility, and (ii) not exceed quarterly operating loss amounts (excluding non-cash contingent consideration associated with the acquisition of Nellix) of $6.5 million for the quarter ended March 31, 2012; $11.0 million for the six months ended June 30, 2012; $13.0 million for the nine months ended September 30, 2012; and $13.0 million for the year ended December 31, 2012.

The Wells Credit Facility also contains a “material adverse change” clause (“MAC”). If the Company encounters difficulties that would qualify as a MAC in its (i) operations, (ii) condition (financial or otherwise), or (iii) ability to repay amounts outstanding under the Wells Credit Facility, it could be canceled at Wells' sole discretion. Wells could then elect to declare the indebtedness, together with accrued interest and other fees, to be immediately due and payable and proceed against any collateral securing such indebtedness.
