Terns Pharmaceuticals, Inc. Debt Disclosure

2020 Notes

In May 2020, the Company issued convertible promissory notes (2020 Notes) in the aggregate amount of $15.0 million. The 2020 Notes had an interest rate of 10.0% per annum, were unsecured, and were due and payable, including accrued interest, in May 2021. In connection with the Series C Convertible Preferred Stock Financing, the 2020 Notes, totaling unpaid principal and accrued interest of $15.9 million, converted into 1,366,820 shares of Series C convertible preferred stock.

Bridge Loan

In May 2020, the Company entered into a bridge loan with Terns China (Bridge Loan) for aggregate proceeds of $1.8 million, payable in renminbi (RMB) at an established USD/RMB exchange rate, based on an average of the previous five working days before May 8, 2020. The Bridge Loan had an interest rate of 10% per year, which began to accrue on the date of drawdown, and was computed based on the actual number of days elapsed based on a year of 365 days. The Bridge Loan holders have the same conversion rights as the 2020 Notes holders.

In connection with the closing of the Series C convertible preferred stock financing in December 2020, entities that are a part of Lilly Asia Ventures (LAV) agreed to effectively convert the Bridge Loan into shares of Series C preferred stock on the same terms as the 2020 Notes. The conversion was to be based on an outstanding loan balance equal to $1.9 million, consisting of (i) the principal loan amount ($1.8 million) plus (ii) accrued interest through December 29, 2020 ($0.1 million).

To help facilitate the transfer of cash from China to the United States to effectively convert the Bridge Loan, the Company and Terns China agreed to enter into an agreement with LAV to (i) repay the Bridge Loan and (ii) issue shares of Series C convertible preferred stock at the initial closing of the Series C financing to entities that are a part of LAV in exchange for a promissory note issued to the Company by LAV, or the LAV Affiliate Promissory Note.

The Bridge Loan was repaid in full by the Company following the requisite government approvals in China. Proceeds from the repayment of the Bridge Loan by Terns China were used by LAV to repay the LAV Affiliate Promissory Note in full. The fair value of the Bridge Loan was determined to be $2.1 million as of December 31, 2020. The Bridge Loan and the LAV Affiliate Promissory Note were paid in full in March 2021.

LAV Series A and Series B Promissory Notes

In November 2020, the Chinese government provided approval for entities affiliated with LAV to exercise the LAV Option (see Note 5, Convertible Preferred Stock). Terns Hong Kong agreed to repurchase all equity interests held by the LAV PRC Entities with proceeds to be used by LAV to purchase shares of Series A convertible preferred stock and Series B convertible preferred stock of the Company (Repurchase).

In December 2020, the Company issued 767,857 shares of Series A convertible preferred stock and 216,450 shares of Series B convertible preferred stock to an affiliate of LAV (LAV Affiliate) in exchange for a promissory note with a principal amount equal to the original investment by LAV in Terns China (LAV Series A and Series B Promissory Note). The LAV Series A and Series B Promissory Note was repaid through proceeds of the Repurchase which was completed in January 2021.

Prior to their repayment, the carrying value of the LAV Series A and Series B Promissory Notes approximated their respective fair value due to the short-term nature of the liability.

The outstanding LAV Series A and Series B Promissory Note was settled in January 2021 and was paid with the proceeds received from the note receivable of $10.8 million. The outstanding Bridge Loan was settled in March

2021 and was substantially paid with the proceeds received from the LAV Affiliate Promissory Note receivable of $1.9 million.
