The K2HV Loan Agreement provides for up to $45.0 million of delayed draw term loans, consisting of (i) the first tranche of $20.0 million available at closing, (ii) the second and third tranches in the aggregate amount of $10.0 million subject to the Company’s achievement of certain clinical milestones related to farudodstat eblasakimab The term loans bear interest at a floating rate equal to the greater of (i) the prime rate published by Wall Street Journal plus 5.00 one-time On July 12, 2021, the full first tranche of $20.0 million available at closing was drawn down. Due to the K2 Warrant described below, the fair value of the first tranche loan on July 12, 2021, wa s $19,311,676. Subsequent to the interest-only period from July 1, 2021, to July 31, 2023, the term loans will be payable in equal monthly instalments of principal plus accrued and unpaid interest, through the maturity date which is July 1, 2025. However, the interest-only period can be extended up to 36 months from the loan closing upon announcement of the achievement of positive data for the Company’s Phase 2b clinical study of eblasakimab Borrowings under the K2HV Facility are secured with a pledge of the borrowers’ equity interests in subsidiaries and collateral over all of the Company’s cash, goods, and other personal property, with the exception of (i) the Company’s registered intellectual property assets, (ii) personal property to the extent that granting of security over any such personal property would constitute a breach of or result in the termination of, or require any consent not obtained under, any license, agreement, instrument or other document evidencing or giving rise to such property, or is otherwise prohibited by any requirement of law, and (iii) the Company’s equity interests in JAGUAHR. Such pledge and collateral may be enforced only if there has been an event of default as stipulated in the loan agreement. As of June 30, 2022, the Company is in full compliance with the loan agreement and there have been no events of default. In connection with the closing of the loan facility, the Company issued a warrant to purchase ordinary shares (the “K2 Warrant”) to K2HV. The number of ordinary shares exercisable under the K2 Warrant equals (i) 2.95% of the aggregate term loan advances made to the Company from time to time divided by (ii) the warrant price of $0.5257 per ordinary share (equivalent to $2.6285 per ADS). The K2 Warrant also includes a cashless exercise feature allowing the holder to receive shares underlying the warrant in an amount reduced by the aggregate exercise price that would have been payable upon exercise of the warrant for such shares. The K2 Warrant is exercisable until its expiration on July 12, 2031. The total proceeds attributed to the K2 Warrant was approximately $688,324 based on the relative fair value as of the date of the drawdown. As the number of ADS to be issued under the cashless method will continue to vary dependent to the share price of the Company, the K2 Warrants do not meet the equity classification and are classified as liability and fair valued though profit and loss. As of December 31, 2021 and June 30 2022, the fair value of the K2 Warrant was revalued t o $223,352 and $119,351 respectively, with the difference of $104,001 being recorded as profit in other gains. See Note 20 for more detail on assumptions used in the valuation of the K2 warrant. On January 5, 2022, the Company drew down the second tranche $5 million in full of the loan facility provided by K2HV pursuant to the Loan Agreement. The second tranche milestone was completed, and the full funds were received on February 4, 2022. As a result of the drawdown of the second tranche of the loan facility, the number of ordinary shares exercisable under the K2 Warrant increased to 1,402,891 (representing 280,578 ADS), based on the 2.95% coverage of the total drawdown facility $25 million, being the aggregate term loan advances at that date, divided by the warrant price of $0.5257 per ordinary share (equivalent to $2.6285 per ADS). As of June 30, 2022, K2HV did not exercise any warrants.

Share-Based Payment Arrangements	17. SHARE-BASED PAYMENT ARRANGEMENTS Employee Share Option Plan Under the Company’s 2014 employee share option plan (the “2014 Plan”), qualified employees of the Company and its subsidiaries were granted 6,850,356 options (representing 13,700,712 ordinary shares post share split) from July 2010 to July 2016, among which 2,199,500 options (representing 4,399,000 ordinary shares post share split) were expired or exercised as of June 30, 2022. The board of directors of the Company, as of July 26, 2016, resolved to double the number of shares underlying each outstanding award granted previously to reflect the subdivision ratio of the share split made in connection with the corporate restructuring of May 27, 2016. The exercise price for each award previously granted was correspondingly adjusted by a decrease o f 50%. The modification did not cause any incremental adjustments to the fair value of the granted awards. Under the Company’s 2017 employee share option plan (the “2017 Plan”), qualified employees of the Company and its subsidiaries were granted 825,833 options in September 2017. Each option entitles the holder to subscribe for one ordinary share of the Company. Options granted pursuant to the 2014 Plan and the 2017 Plan are all vested in full or expired as of June 30, 2022. On December 10, 2020, the Board of Directors (the “Board”) of the Company approved the Company’s 2020 Equity Incentive Plan (the “2020 EIP”). The 2020 EIP, among other things, provides for the grant of restricted stock awards, stock options and other equity-based awards to employees, officers, directors, and consultants. The maximum number of ordinary shares that may be issued under the 2020 EIP was originally ordinary shares (an equivalent of ADS of the Company, each ADS representing five ordinary shares). On December 15, 2020 , and options were granted under the Company’s 2020 EIP, respectively. Each option entitles the holder to subscribe for one ADS of the Company. The options granted are valid for years. No performance conditions were attached to the plan. No more than ordinary shares (an equivalent of ADS) may be issued under the 2020 EIP upon the exercise of incentive stock options. In addition, the number of ordinary shares reserved for issuance under the 2020 EIP will automatically increase on January 1 of each year, commencing on January 1, 2022 , In connection with the approval of the 2020 EIP, the Board determined that there would be no increase for January 1, 2021, but there would be an increase of 13,948,935 ordinary shares (an equivalent o f 2,789,787 ADS) represent ing 4% of the total outstanding ordinary shares as of December 31, 2021. 8,875,745 ordinary shares (an equivalent of 1,775,149 ADS) were granted on January 1, 2022. If an award under the 2020 EIP expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, cancelled without having been fully exercised, forfeited or is withheld to satisfy a tax withholding obligation in connection with an award or to satisfy a purchase or exercise price of an award, any unused shares subject to the award will, as applicable, become or again be available for new grants under the 2020 EIP. Awards granted under the 2020 EIP in substitution for any options or other equity or equity-based awards granted by an entity before the entity’s merger or consolidation with the Company or the Company’s acquisition of the entity’s property or stock will not reduce the number of ordinary shares available for grant under the 2020 EIP but will count against the maximum number of ordinary shares that may be issued upon the exercise of incentive stock options. Information on employee share options granted under the 2014 Plan is as follows. Each option entitles the holder to subscribe for two ordinary shares of the Company due to the 2016 share split (1 ADS represents 5 ordinary shares).

Financial risk management objectives and policies The Company’s financial risk management objective is to monitor and manage the financial risks relating to the operations of the Company. These risks include market risk (including foreign currency risk and interest rate risk), credit risk and liquidity risk. To minimize the effect of financial risks, the Company devoted time and resources to identify and evaluate the uncertainty of the market to mitigate risk exposures. 1) Market risk The Company’s activities exposed it primarily to the financial risks of changes in foreign currency exchange rates (see (a) below) and interest rates (see (b) below). a) Foreign currency risk The Company had foreign currency transactions, which exposed the Company to foreign currency risk. The Company’s significant financial assets and liabilities denominated in foreign currencies were as follows: December 31, 2021 Foreign Exchange Rate Carrying Financial assets Monetary items SGD S$ 837,336 0.7411 $ 620,563 Financial liabilities Monetary items SGD S$ 15,649,526 0.7411 $ 11,598,118 June 30, 2022 Foreign Exchange Rate Carrying Financial assets Monetary items SGD S$ 1,954,107 0.7189 $ 1,404,751 Financial liabilities Monetary items SGD S$ 15,858,480 0.7189 $ 11,400,203 Sensitivity analysis The Company is mainly exposed to the Singapore Dollar. The following table details the Company’s sensitivity to a 5% increase and decrease in the U.S. dollar against the relevant foreign currency. The rate of 5% is the sensitivity rate used when reporting foreign currency risk internally to key management personnel and represents management’s assessment of the reasonably possible change in foreign exchange rates. The sensitivity analysis includes only outstanding foreign currency denominated monetary items. A positive number below indicates a decrease in pre-tax pre-tax For the six months ended June 30 2021 2022 Profit or loss* SGD $ (487,150 ) $ (499,773 ) * This is mainly attributable to the exposure to outstanding deposits in banks and loans in foreign currency at the end of the reporting period. b) Interest rate risk The Company is exposed to interest rate risk because entities in the Company borrowed funds at fixed baseline interest plus floating interest rates. The sensitivity analysis below is determined based on the Company’s exposure to interest rates for fixed rate borrowings at the end of the reporting period and is prepared assuming that the amounts of liabilities outstanding at the end of the reporting period are outstanding for the whole year. A 100 If interest rates had been 10 pre-tax , 2) Credit risk Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in a financial loss to the Company. The Company adopted a policy of only dealing with creditworthy counterparties and financial institutions, where appropriate, as a means of mitigating the risk of financial loss from defaults. 3) Liquidity risk The Company manages liquidity risk by monitoring and maintaining a level of cash and cash equivalents that are deemed adequate to finance the Company’s operations and mitigate the effects of fluctuations in cash flows. In addition, management monitors the utilization of long-term borrowings and ensures compliance with repayment conditions. As the Company is in the research and development phase, the Company will be seeking future funding based on the requirements of its business operations. The Company is able to exercise discretion and flexibility to deploy its capital resources in the process of the research and development activities according to the schedule of fund raising. The Company intends to explore various means of fundraising to meet its funding requirements to carry out the business operations, such as the issuance of its ordinary shares sponsoring ADS. The Company may also use other means of financing such as out licensing to generate revenue and cash. Management believes that it currently has plans and opportunities in place which will allow to fund and meet its operating expenses and capital expenditure requirements and meet its obligations for at least the next twelve months from June 30, 2022. On February 25, 2021, and March 4, 2021, the Company had completed a private placement raising for gross proceeds of $18.0 million and closed a public offering with gross proceeds $69.0 million. Further, the Company has an ATM Sales Agreement with Jefferies LLC, pursuant to which it raised net proceeds of $14.1 million during the year ended December 31, 2021.
