On October 3, 2016 (the “Closing Date”), Cidara Therapeutics, Inc. (the “Company”), entered into a Loan and Security Agreement (the “Loan Agreement”) with Pacific Western Bank (“Lender”), under which the Company borrowed 10.0 million dollars on the Closing Date. Subject to the terms and conditions of the Loan Agreement, including the Company’s achievement of specified milestones in the Loan Agreement (the “Milestones”), the Company may borrow an additional 10.0 million dollars through April 3, 2018 (the “Tranche B Draw Period”). The Tranche B Draw Period shall be extended to October 3, 2018, if the Company achieves the Milestones. The Company intends to use the proceeds received under the Loan Agreement for its research and development activities, including its preclinical and clinical development programs, and for general corporate purposes.

The interest rate will be calculated at a floating annual rate equal to the greater of either (i) 1.00% plus the prime rate used by Lender, and (ii) 4.50%. Payments under the Loan Agreement are interest-only for 18 months from the Closing Date, which would be extended to 24 months upon the Company achieving the Milestones. The interest-only period will be followed by equal monthly payments of principal, plus accrued interest, amortized over a 30 month schedule through the maturity date of October 3, 2020 (the “Loan Maturity Date”); provided that if the Milestones are achieved, the Company will make equal monthly payments of principal, plus accrued interest, amortized over a 24 month schedule through the Loan Maturity Date. The remaining principal balance and any accrued and unpaid interest will be due and payable on the Loan Maturity Date. The Company’s obligations under the Loan Agreement are secured by a security interest in substantially all of its assets, other than its intellectual property, which is subject to a double negative pledge.

If the Company prepays any term loan, during the first 12 months following the advance date of such term loan, it will pay Lender a prepayment fee equal to 2.00% of the principal amount prepaid; if the prepayment occurs during months 13 through 24 from the advance date of any term loan, it will pay Lender a prepayment fee equal to 1.00% of the principal amount prepaid. If the prepayment occurs 24 months after the advance date of a term loan, there is no prepayment fee. Pursuant to the Loan Agreement, on the Closing Date, the Company issued to the Lender, a warrant (the “Warrant”) to purchase an aggregate of up to 17,331 shares of the Company’s common stock at an exercise price of $11.54 per share. If the Company borrows additional amounts under the Loan Agreement, it will, in connection with any such borrowing, issue Lender an additional Warrant to purchase that number of shares of the Company’s common stock as is equal to 2.00% of the additional principal amount borrowed divided by the exercise price. The exercise price shall be equal to the 30-day average closing price of the Company’s common stock, calculated as of the date immediately prior to the date of such additional borrowing. The Warrants will expire ten years from the date of the grant.

The Loan Agreement includes customary affirmative and restrictive covenants and also includes standard events of default, including payment defaults. Upon the occurrence of an event of default, Lender may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Loan Agreement. The Loan Agreement also includes an operating covenant, which requires the Company to achieve the Milestones on or before December 31, 2017, which date may be extended to March 31, 2018 if the Company raises at least 20.0 million dollars in equity after the Closing Date and prior to December 31, 2017.
