Item 4 is hereby amended and supplemented as follows: Mr. Urvan, through his designee GDI Air III, will receive Warrant No. 1 in connection with the 2025 Settlement as of the 2025 Settlement Effective Date. As previously disclosed in amendments to Schedule 13D filed by Mr. Urvan on November 7, 2022 and November 22, 2022 (such Schedule 13D, as amended to date, the "Schedule 13D"), the Issuer, Mr. Urvan, and Susan T. Lokey (Mr. Urvan, Susan T. Lokey, and their respective affiliates, collectively, the "Urvan Group") are parties to a settlement agreement originally entered into as of November 2, 2022 and amended on November 21, 2022 (as amended to date, the "2022 Settlement Agreement"). In connection with the 2025 Settlement, the 2022 Settlement Agreement was further amended on May 20, 2025 (the "May 2025 Amendment"). The May 2025 Amendment amends the 2022 Settlement Agreement to provide, among other things, that, until three years following the 2025 Settlement Effective Date: (a) the Urvan Group will vote all shares of Common Stock beneficially owned by it and over which it has direct or indirect voting power, up to a maximum of 17,312,857 shares, in accordance with the recommendations of the Issuer's board of directors (the "Board") with respect to (i) the election, removal, and/or replacement of directors; and (ii) any other proposal submitted to stockholders, except in certain specified, limited circumstances regarding extraordinary transactions that would result in a change in control of the Issuer or the sale of substantially all of its assets; (b) the Urvan Group will not, without the approval of the Board, (i) sell any of its shares of Common Stock, other than in open market transactions where the identity of the purchaser is not known and in underwritten widely dispersed public offerings, to any third party that, to the Urvan Group's knowledge would result in such third party having any beneficial or other ownership interest of more than 4.9% in the aggregate of the shares of Common Stock outstanding at the time of such sale; (ii) other than as otherwise provided in the 2022 Settlement Agreement as amended by the May 2025 Amendment, (A) nominate, recommend for nomination, or give notice of an intent to nominate or recommend for nomination a person for election at any meeting of the Issuer's stockholders at which directors are to be elected; (B) knowingly initiate, encourage, or participate in any solicitation of proxies in respect of any election contest or removal contest with respect to the Issuer's directors; (C) submit, initiate, make, or be a proponent of any stockholder proposal for consideration at, or bring any other business before, any meeting of the Issuer's stockholders; (D) knowingly initiate, encourage, or participate in any solicitation of proxies in respect of any stockholder proposal for consideration at, or other business brought before, at any meeting of the Issuer's stockholders; or (E) knowingly initiate, encourage or participate in any "withhold" or similar campaign with respect to any meeting of the Issuer's stockholders; in each case other than in a manner consistent with the Board's recommendation in connection with such matter; (iii) form, join or in any way participate in any group or agreement of any kind with respect to any voting securities of the Issuer, other than a group that is solely among the members of the Urvan Group; (iv) knowingly initiate, make or in any way participate, in any extraordinary transaction that would result in a change in control of the Issuer or the sale of substantially all of its assets or make any proposal to the Issuer or the Board that would reasonably be expected to require a public announcement or disclosure regarding any such matter; (v) effect or seek to effect, offer, or propose to effect, cause or participate in, or in any way knowingly assist or facilitate any other person to effect or seek, offer, or propose to effect or participate in any (A) material acquisition of any assets or businesses of the Issuer or any of its subsidiaries; (B) tender offer or exchange offer, merger, acquisition, share exchange, or other business combination involving any of the voting securities or any of the material assets or businesses of the Issuer or any of its subsidiaries; or (iii) recapitalization, restructuring, liquidation, dissolution, or other material transaction with respect to the Issuer or any of its subsidiaries or any material portion of its or their businesses; or (vi) enter into any negotiations, agreements, or understandings with any third party with respect to the foregoing, or knowingly advise, assist, encourage, or seek to persuade any third party to take any action with respect to any of the foregoing, or otherwise take or cause any action inconsistent with any of the foregoing.
