- F1. Each share of Series A-1 non-voting convertible preferred stock is convertible automatically upon receipt of stockholder approval under applicable Nasdaq rules and regulations in connection with the Issuer's private placement pursuant to which the Pre-Funded Warrants were issued ("Stockholder Approval") into a number of shares of the Issuer's common stock equal to $1,000 divided by $0.14, pursuant to the terms of the Series A-1 Certificate of Designation and subject to applicable beneficial ownership limitations.
- F2. The Pre-Funded Warrant has no expiration date and is exercisable immediately.

To the extent FDA approval of seralutinib does not occur on or prior to the date that is two years following the grant date of the option, 1/24th of the total number of shares subject to the option will vest on the last day of each one-month period following the date that is two years following the grant date of the option, subject to the Reporting Person's continuous service to the Issuer on each such vesting date.

Pre-Funded Warrant financial
"The Pre-Funded Warrant has no expiration date and is exercisable immediately."
A pre-funded warrant is a financial instrument that gives the holder the right to buy shares of a company's stock at a set price, with most of the purchase cost already paid upfront. It functions like a nearly fully paid option, allowing investors to secure shares quickly while minimizing the amount of additional money they need to invest later. This helps investors gain ownership rights efficiently, often used to avoid certain regulatory restrictions or to prepare for future stock purchases.
Series A-1 non-voting convertible preferred stock financial
"Each share of Series A-1 non-voting convertible preferred stock is convertible"
beneficial ownership limitations regulatory
"subject to applicable beneficial ownership limitations."
Beneficial ownership limitations are rules or contractual caps that restrict how much of a company’s stock an individual or entity can be treated as owning or controlling for legal, regulatory or corporate-governance purposes. They matter to investors because such limits affect voting power, reporting obligations, takeover risk and the ability to increase a stake — like an elevator weight limit or a lane divider that prevents any one car from taking over the whole road.
Stockholder Approval regulatory
"convertible automatically upon receipt of stockholder approval under applicable Nasdaq"
Stockholder approval is formal consent given by a company’s shareholders, usually through a vote at a meeting or by proxy, for major actions such as mergers, asset sales, changes to corporate structure, or amendments to governance rules. Investors pay attention because the vote can enable or block steps that materially change a company’s direction, ownership or value—like neighbors voting to allow a major renovation that would alter a building’s use and worth.
