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, which 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.

In September 2011, the Company incurred a commitment fee of $40,000 and loan fees of $50,000, which were recorded as a discount to its Growth Capital Loan and were being amortized as a component of interest expense using the effective interest method over the term of the Growth Capital Loan (discount was based on an implied interest rate of 7.07%). The Company was also required to make a final payment fee of 1% of the amounts drawn under the Growth Capital Loan due on its prepayment of the Growth Capital Loan. The final payment fee was accreted to interest expense using the effective interest method over the life of the Growth Capital Loan upon draw. The remaining unaccreted balance of the final payment fee and unamortized discount will be taken as an interest charge in April 2013 in connection with the repayment of that 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, 2013, and December 31, 2012, the Company had $2.8 million and $3.2 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, 2013, and December 31, 2012, the floating rate of the RLOC was at 4.75%. In September 2011, the Company incurred a commitment fee of $20,000. Upon amendment of the loan and security agreement in June 2012, the Company incurred another annual commitment fee of $20,000 and received a credit for the unused portion of the initial fee. The Company will incur a $20,000 commitment fee at each annual anniversary beginning June 30, 2013.

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, 2013, the Company was in compliance with the financial covenants as set forth in the Amended Credit Agreement.
