Item 6. | Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer |
On April 15, 2025, RTW Investments and certain of the RTW Funds entered into the Second Amendment to the Note Purchase Agreement, which amends the Amended Note Purchase Agreement described in Item 4 to Amendment No. 1 to this Schedule 13D. The Second Amendment granted the RTW Funds additional conversion rights as follows, with such additional conversion rights being exempt from the beneficial ownership limitation contained in the Amended Note Purchase Agreement:(i) In the event that the Market Capitalization Condition (as defined in the Second Amendment) has been triggered, the RTW Funds agreed to provide the Company with, and the Company agreed to accept, a conversion notice to convert $5.0 million aggregate principal amount of the Notes at a conversion rate equal to 298.5075 Shares per $1,000 principal amount of Notes, reflecting a floor conversion price of $3.35 per share (the "Floor Conversion Rate") for an aggregate of 1,492,539 Shares.(ii) In the event that the Market Capitalization Condition is triggered, the RTW Funds may provide a conversion notice to the Company to convert up to $5.0 million aggregate principal amount of the Notes into Shares at a conversion rate mutually agreed upon by the RTW Funds and the Company, with such conversion rate not being less than the Floor Conversion Rate. The Company may accept or reject such notice in its sole discretion.(iii) At any time, the RTW Funds may provide to the Company a notice to convert up to $5 million aggregate principal amount of the Notes into Shares at a rate equal to the lesser of (i) the quotient of $1,000 divided by the Daily VWAP (as defined in the Amended Note Purchase Agreement) for the period specified in such notice discounted by 5%, calculated based on the five consecutive trading days ending on the trading day immediately preceding the date of the notice, and (ii) the Floor Conversion Rate (the "5-Day VWAP Conversion Rate"). The Company may accept or reject such notice in its sole discretion.(iv) A maximum of once per month until April 15, 2026, the RTW Funds may provide to the Company a notice to convert up to an additional $1 million aggregate principal amount of the Notes in any 30-day period into Shares at the 5-Day VWAP Conversion Rate. The Company may accept or reject such notice in its sole discretion. If the RTW Funds do not exercise their right to provide such monthly conversion notice for all or a portion of such monthly amount, or if the Company does not a
ccept such notice, the RTW Funds are permitted to include any such unused amount in any subsequent monthly conversion notice.In addition, the parties to the Second Amendment confirmed that the conversion rate applicable to conversions of the Notes pursuant to Section 4.1 of the Amended Note Purchase Agreement will continue to be equal to 24.6920 Shares per $1,000 principal amount.The RTW Funds also agreed that, until the earlier of (i) the effective date of any Fundamental Change or Make-Whole Fundamental Change (each as defined in the Amended Note Purchase Agreement) and (ii) the date on which the RTW Funds and their affiliates collectively hold less than 9.99% of the voting power of the outstanding Shares of the Company, the RTW Funds will, at any meeting of the Company' stockholders, abstain from voting Shares acquired pursuant to the additional conversion rights provided by the Second Amendment (the "Relevant Shares"), or vote the Relevant Shares in proportion to the votes cast on the applicable matter with respect to the Shares beneficially owned by persons other than the RTW Funds or any of their affiliates.On April 16, 2025, the RTW Funds provided the Company with, and the Company accepted, a conversion notice (the "Conversion Notice"), pursuant to which $5.0 million aggregate principal amount of the Notes was converted into 1,492,539 shares.The foregoing description of the Second Amendment to the Note Purchase Agreement is not complete and is qualified in its entirety by reference to the complete text of the Second Amendment to the Note Purchase Agreement, which is filed as Exhibit 99.21 to this Amendment No. 8 to the Schedule 13D and incorporated by reference to this Item 6. | |
