2011 Growth Capital Facility

The Company entered into a loan and security agreement on September 30, 2011, as amended effective on December 13, 2011, and June 30, 2012, with Comerica Bank (“Comerica”) (collectively, the “Amended Credit Agreement”). The Amended Credit Agreement provides for an aggregate borrowing of up to $12.0 million, comprised of a growth capital loan of $5.0 million (“Growth Capital Loan”) and a formula based revolving line of credit (“RLOC”) of up to $7.0 million. The Company pledged all current and future assets, excluding its intellectual property and 35% of the Company’s investment in its subsidiary, Cerus Europe B.V., as security for borrowings under the Amended Credit Agreement.

Growth Capital Loan

Concurrent with the execution of the original loan and security agreement in September 2011, the Company borrowed $5.0 million under the Growth Capital Loan, substantially all of which was used to repay the Company’s prior debt with Oxford Finance Corporation (“Oxford”), with the remainder used for general corporate purposes. The Growth Capital Loan was scheduled to mature on September 30, 2015 and bore a fixed interest rate of 6.37%, with interest–only payments due for the first twelve months, followed by equal principal and interest payments for the remaining 36 months. In April 2013, the Company repaid in full the Growth Capital Loan balance and all accrued interest as well as a scheduled final payment fee of $0.05 million, in an aggregate amount of $4.2 million. The Company has no further obligations under the Growth Capital Loan.

Revolving Line of Credit

The Amended Credit Agreement also provides for a RLOC of up to $7.0 million (the “RLOC Loan Amount”). The amount available under the RLOC is limited to the lesser of (i) 80% of eligible trade receivables or (ii) the RLOC Loan Amount. At March 31, 2014, and December 31, 2013, the Company had $3.3 million and $3.4 million, respectively, outstanding under the RLOC. The Company is required to repay the principal drawn from the RLOC at the end of the RLOC term on June 30, 2014, or earlier if a portion or all of the outstanding RLOC exceeds the amount available under the RLOC. The RLOC bears a floating rate based on the lender’s prime rate plus 1.50%, with interest–only payments due each month. At both March 31, 2014, and December 31, 2013, the floating rate of the RLOC was 4.75%.

Compliance with Covenants

The Company is required to maintain compliance with certain customary and routine financial covenants under the Amended Credit Agreement, including maintaining a minimum cash balance of $2.5 million at Comerica and achieving minimum revenue levels, which are measured monthly based on a six-month trailing basis and must be at least 75% of the pre-established future projected revenues for the trailing six-month period. Non-compliance with the covenants could result in the principal of the note becoming due and payable. As of March 31, 2014, the Company was in compliance with the financial covenants as set forth in the Amended Credit Agreement.
