Capitalized terms used herein shall have the meanings set forth in Section 5 of this Agreement.

WHEREAS, on May 13, 2024, the Company launched an initial public offering of its shares of common stock (“Company Common Stock”) pursuant to a registered underwritten public offering (the “Company IPO”);

WHEREAS, as of the consummation of the Company IPO, the Investor will own (a) 26.1% of the outstanding Class A Interests (as defined in the Amended & Restated LPA) of BIHL, which entitles the Investor, upon completion of the Reorganization Transaction, to a number of shares of Company Common Stock and (ii) a warrant to purchase 1,576,667 shares of Company Common Stock (or up to 1,626,667 shares of Company Common Stock if the underwriters’ over-allotment option in connection with the Company IPO is exercised in full) (the “Warrant”); and

1.    Maintenance of Ownership. During the period beginning on the date of this Agreement and ending on the third (3rd) anniversary thereof (the “Maintenance Period”), the Investor (i) shall maintain (A) at all times prior to the completion of the Reorganization Transaction, ownership of Class A Interests of BIHL that would entitle the Investor upon completion of the Reorganization Transaction to a number of shares of Company Common Stock equal to at least ten percent (10%) of the issued and outstanding shares of Company Common Stock (which shares owned by the Investor shall include shares subject to the Warrant, to the extent vested (assuming there is no cashless exercise)) and (B) at all times following the completion of the Reorganization Transaction, ownership of shares of Company Common Stock equal to at least ten percent (10%) of the issued and outstanding shares of Company Common Stock (which shares owned by the Investor shall include shares subject to the Warrant, to the extent vested (assuming there is no cashless exercise)) (each of the amounts set forth in clause (A) and (B), the “Minimum Ownership Amount”), (ii) shall report the Company and each of the Company’s wholly owned subsidiaries as an Affiliate for all insurance statutory accounting and regulatory purposes, (iii) for purposes of the Reinsurance Agreement, shall treat BIC as an Affiliate, and (iv) shall not make any filing with, or make any communication (written or oral) to, any Governmental Authority, or take any other action, that would reasonably be likely to result in the Investor no longer being deemed an Affiliate of the Company; provided, however, that in no event shall the Investor be required to acquire additional Class A Interests or shares of Company Common Stock in the event additional interests in BIHL are issued or the Company issues additional shares. Subject to the foregoing proviso, during the Maintenance Period, the Investor agrees that BIC shall be entitled to treat the Investor as an Affiliate for all insurance statutory accounting and regulatory purposes. For purposes of this Section 1, “Affiliate” of the Company or of BIC shall have the meaning ascribed to it under SSAP No. 88, Investments in Subsidiary, Controlled, and Affiliated Entities.

2.    Board Representatives.

Agreement (as set forth therein, including as a result of the termination of such agreements) (the later of (i) and (ii), the “Representation Expiration Date”), at every applicable annual meeting of the stockholders of the Company in which directors are generally elected (or special meeting in lieu of an annual meeting at which directors are to be elected and adjusted as appropriate to take into account the Company’s classified Board structure), the Investor shall have the right to recommend to the Company (A) one (1) individual to serve as a Class I director and (B) one (1) individual to serve as a Class II director (such individuals, the “Board Nominees” and each a “Board Nominee”) on the Board of Directors of the Company (the “Board”); provided, however, that any such director nominee shall be reasonably satisfactory to the applicable committee of the Board with authority over nominations of individuals to serve as directors of the Company. Each of Troy Van Beek and David Holman shall be a Board Nominee for purposes of this Agreement, including Section 2(h), such persons having been deemed to be reasonably satisfactory to the applicable committee of the Board with authority over nominations of individuals to serve as directors of the Company.

(b)    If the Investor is no longer entitled to two (2) Board Nominees in accordance with the foregoing Section 2(a), then so long as the Investor continues to own the Minimum Ownership Amount, at every applicable annual meeting of the stockholders of the Company in which directors are generally elected (or special meeting in lieu of an annual meeting at which directors are to be elected and adjusted as appropriate to take into account the Company’s classified Board structure), the Investor shall have the right to recommend to the Company one individual to serve as a Class I director of the Company as a Board Nominee; provided, however, that any such director nominee shall be reasonably satisfactory to the applicable committee of the Board with authority over nominations of individuals to serve as directors of the Company.

(c)    If any Board Nominee is deemed not reasonably satisfactory in accordance with the foregoing paragraphs, the Investor will be given a reasonable opportunity to select another individual to serve as Board Nominee. If any Board Nominee is not elected by the stockholders at any annual meeting held during the period in which the Investor is entitled to Board Nominees pursuant to the foregoing Section 2(a) or 2(b), then as soon as practicable after the annual meeting, the applicable Board Nominee (or such other person acceptable to the Investor and the Board) shall be appointed as a director by the Board promptly following such annual meeting to the same class as the applicable Board Nominee were originally nominated for. In addition, if a vacancy is created on the Board as a result of the death, disability, retirement, resignation (other than a resignation required by Section 2(h)) or removal of a Board Nominee, then the Investor shall have the right to recommend such person’s replacement to be appointed to the same class as the applicable Board Nominee prior to the next annual meeting of stockholders, which recommendation shall be considered in good faith by the Board. For the avoidance of doubt, each reference in this Section 2(d) to “annual meeting” shall also be deemed a reference to a special meeting held in lieu of an annual meeting during the period in which the Investor is entitled to Board Nominees pursuant to this Agreement.

(d)    For so long as the Investor has the right to nominate any nominee(s) for election as a Class I or Class II director pursuant to this Section 2 (subject to the provisos in Section 2(a) and 2(b) above), the Company shall nominate such nominee(s) for election as a director as part of the applicable slate that is included in the proxy statement (or consent solicitation or similar document) of the Company (or such other person) relating to the election of directors, and shall provide the highest level of support for the election of such nominee(s), as the case may be, as it provides to any other individual standing for election as a director of the Company (or such other person) as part of the Company’s (or such other person’s) slate of directors.

(g)    Notwithstanding anything to the contrary herein, the Investor’s right to recommend the Board Nominee(s) pursuant to Section 2(a) and 2(b) and all related rights of the Investor and obligations of the Company set forth in this Section 2 shall terminate immediately upon the termination of the Reinsurance Agreement and the MGA Agreements (notwithstanding any continuing provisions in Section 4.05 of the Reinsurance Agreement or Section 14.9 of the MGA Agreements) at any time prior to the five (5) year anniversary of the consummation of the Company IPO.

(h)    In the event (i) the Representation Expiration Date shall occur, (ii) the Investor fails to maintain the Minimum Ownership Amount or (iii) this Agreement terminates pursuant to Section 2(g), then each Board Nominee shall promptly offer to resign from the Board and, if requested by the Company, promptly deliver his or her written resignation to the Board (which shall provide for his or her immediate resignation), it being understood that it shall be in the Board’s sole discretion whether to accept or reject such resignation; provided, however, if two Board Nominees are on the Board and the Investor continues to have the right to one Board Nominee pursuant to Section 2(b), then only the current Class II Board Nominee shall promptly offer to resign from the Board and, if requested by the Company, promptly deliver his or her written resignation to the Board (which shall provide for his or her immediate resignation), it being understood that it shall be in the Board’s sole discretion whether to accept or reject such resignation. The Investor agrees to cause the Board Nominees to resign from the Board if the Board Nominees fail to resign if and when contemplated by this Section 2(h).

(i)    On and as of the date on which the Investor owns less than the Minimum Ownership Amount for any reason other than solely dilution resulting from the issuance of additional Common Stock by the Company where the Investor has not sold more than 35% of the shares of Common Stock held by the Investor following the date of this Agreement (or, if earlier terminated pursuant to Section 2(g), on and as of such termination date), all of the nomination rights of the Investor set forth in this Section 2 shall terminate in full and be of no further force or effect, regardless of any increase in the amount of Common Stock that the Investor owns after such date.

3.    MGA Agreements.
