NOW, THEREFORE, the parties agree as follows: ARTICLE 1 Sale and Purchase of Shares Section 1.1 Sale and Purchase of Shares. Subject to the terms and conditions hereof, at the Closing, Seller shall sell the Shares to Buyer, and Buyer shall purchase the Shares from Seller, for the Purchase Price. Section 1.2 Purchase Price. (a) The purchase price payable by Buyer to Seller for the Shares shall be an aggregate amount equal to the sum of (a) $420,000,000, plus (b) the Adjustment Amount (the “Purchase Price”). (b) At least five (5) Business Days prior to the Closing Date, Seller shall prepare in good faith and deliver to Buyer (1) a statement (the “Closing Statement”), certified by the Chief Financial Officer of Seller, setting forth the amount of (i) the First Adjustment, (ii) the Second Adjustment, (iii) the aggregate amount of Company Payments, if any, (iv) the Adjustment Amount and (v) the Purchase Price resulting

therefrom, in each case, together with reasonably detailed supporting documentation and calculations related thereto and (2) a statement setting forth the accrued liabilities as described in Section 4.6(i) and Section 4.6(j), in each case as of the most recent calendar quarter end (the “Preliminary Benefits Accounts”), which shall be settled in accordance with Section 4.6. The Purchase Price as set forth in the Closing Statement shall be payable at Closing as set forth in Section 1.3. The Purchase Price shall be subject to adjustment after the Closing as set forth in (c). (c) Purchase Price True-Up (i) Buyer shall have sixty (60) days after the Closing Date to review the Closing Statement (such period of time, the “Review Period”). The Closing Statement shall become final and binding at 11:59 p.m. New York City time on the 30th day of the Review Period, unless Buyer gives written notice of its disagreement with the Closing Statement (such written notice, a “Notice of Disagreement”) to Seller on or prior to such date. During the Review Period, Seller shall make available to Buyer and its Representatives access to any information and personnel as reasonably required by Buyer in connection with its review of the Closing Statement. Any Notice of Disagreement shall specify in reasonable detail the nature of any disagreement so asserted. If a Notice of Disagreement is delivered to Seller in a timely manner, then the Closing Statement (as revised in accordance with this sentence) shall become final and binding upon Seller and Buyer on the earlier of (A) the date Seller and Buyer resolve in writing any differences they have with respect to the matters specified in the Notice of Disagreement or (B) the date any disputed matters are finally resolved in writing by the Independent Accounting Firm. (ii) During the fifteen (15) day period following the delivery of a Notice of Disagreement (such period of time, the “Resolution Period”), Seller and Buyer shall seek in good faith to resolve in writing any differences that they may have with respect to the matters specified in the Notice of Disagreement. During the Resolution Period, each party and its auditors shall have access to the working papers of the other party and other supporting documentation used in preparation of the Closing Statement or the Notice of Disagreement. In the event that Seller and Buyer do not agree on any item or items shown or reflected in the Closing Statement within the Resolution Period, each of Seller and Buyer shall prepare separate written reports of such unresolved item or items and deliver such reports to the Independent Accounting Firm within 15 days after the expiration of the Resolution Period. The parties shall use their respective commercially reasonable efforts to cause the Independent Accounting Firm to, as soon as practicable and in any event within 15 days after receiving such written reports, determine the manner in which such item or items shall be treated in the Closing Statement; provided, however, that the dollar amount of each item in dispute shall be

determined within the range of dollar amounts proposed by Seller, on the one hand, and Buyer, on the other hand. The parties acknowledge and agree that (i) the review by and determinations of the Independent Accounting Firm shall be limited to, and only to, the unresolved item or items contained in the reports prepared and submitted to the Independent Accounting Firm by Seller and Buyer and (ii) the determinations by the Independent Accounting Firm shall be based solely on such reports submitted by Seller and Buyer and the basis for Seller’s and Buyer’s respective positions. Seller and Buyer agree to enter into an engagement letter with the Independent Accounting Firm containing customary terms and conditions for this type of engagement. The parties shall use their commercially reasonable efforts to cooperate with and provide information and documentation, including work papers, to assist the Independent Accounting Firm. Any such information or documentation provided by either party to the Independent Accounting Firm shall be concurrently delivered to the other party, subject, in the case of the Independent Accounting Firm’s work papers, to such other party entering into a customary release agreement with respect thereto. Neither party shall disclose to the Independent Accounting Firm, and the Independent Accounting Firm shall not consider for any purposes, any settlement discussions or settlement offers made by either party with respect to any objection under this Section 1.2. The determinations by the Independent Accounting Firm as to the item or items in dispute shall be in writing and shall be final, binding and conclusive for all purposes of determining the Purchase Price and shall have the same effect for all purposes as if such determinations had been embodied in a final judgment, entered by a court of competent jurisdiction, and either party may petition a court of competent jurisdiction in accordance with Section 9.5 to reduce such decision to judgment. The fees, costs and expenses of retaining the Independent Accounting Firm shall be borne 50% by Seller and 50% by Buyer. Following the resolution of all disputed items (or, if there is no dispute, promptly after the parties reach agreement on the Closing Statement), Buyer shall revise the Closing Statement to reflect the resolution of any disputed items (as so revised, the “Final Closing Statement”) and shall deliver a copy thereof to Seller. Seller will indemnify and hold Buyer and its Affiliates harmless from and against any Company Payments to the extent they were not reflected on (or not taken into account and resolved pursuant to the dispute resolution process set forth above with respect to) the Final Closing Statement. Buyer and its Affiliates may not make any claim for indemnification pursuant to the immediately preceding sentence after April 30, 2026. (iii) With respect to the adjustment to the Purchase Price, if any, contained in the Final Closing Statement, the applicable party shall pay to the other party by wire transfer of immediately available funds, within ten (10) Business Days following the delivery of the Final Closing Statement, to an account or accounts designated by the receiving party in writing.

(d) Closing Benefits Accounts (i) Within forty-five (45) days after the Closing Date, Seller shall provide to Buyer the accrued liabilities as described in Section 4.6(i) and Section 4.6(j), in each case as of the Closing Date (the “Closing Benefits Accounts”). (ii) Buyer shall have thirty (30) days after the date Buyer receives the information set forth in the foregoing clause d(i) to review the Closing Benefits Accounts (such period of time, the “Benefits Accounts Review Period”). The Closing Benefits Accounts shall become final and binding at 11:59 p.m. New York City time on the 30th day of the Benefits Accounts Review Period, unless Buyer gives written notice of its disagreement with the Closing Benefits Accounts (such written notice, a “Benefits Accounts Notice of Disagreement”) to Seller on or prior to such date. During the Benefits Accounts Review Period, Seller shall make available to Buyer and its Representatives access to any information and personnel as reasonably required by Buyer in connection with its review of the Closing Benefits Accounts. Any Benefits Accounts Notice of Disagreement shall specify in reasonable detail the nature of any disagreement so asserted. If a Benefits Accounts Notice of Disagreement is delivered to Seller in a timely manner, then the Closing Benefits Accounts (as revised in accordance with this sentence) shall become final and binding upon Seller and Buyer on the earlier of (A) the date Seller and Buyer resolve in writing any differences they have with respect to the matters specified in the Benefits Account Notice of Disagreement or (B) the date any disputed matters are finally resolved in writing by the Independent Accounting Firm. (iii) During the fifteen (15) day period following the delivery of a Benefits Accounts Notice of Disagreement (such period of time, the “Benefits Accounts Resolution Period”), Seller and Buyer shall seek in good faith to resolve in writing any differences that they may have with respect to the matters specified in the Benefits Accounts Notice of Disagreement. During the Benefits Accounts Resolution Period, each party and its auditors shall have access to the working papers of the other party and other supporting documentation used in preparation of the Closing Benefits Accounts or the Benefits Accounts Notice of Disagreement. In the event that Seller and Buyer do not agree on any item or items shown or reflected in the Closing Benefits Accounts within the Benefits Accounts Resolution Period, each of Seller and Buyer shall prepare separate written reports of such unresolved item or items and deliver such reports to the Independent Accounting Firm within 15 days after the expiration of the Benefits Accounts Resolution Period. The parties shall use their respective commercially reasonable efforts to cause the Independent Accounting Firm to, as soon as practicable and in any event within 15 days after receiving such written reports, determine the manner in which such item or items shall be treated in the Closing

Benefits Accounts; provided, however, that the dollar amount of each item in dispute shall be determined within the range of dollar amounts proposed by Seller, on the one hand, and Buyer, on the other hand. The parties acknowledge and agree that (i) the review by and determinations of the Independent Accounting Firm shall be limited to, and only to, the unresolved item or items contained in the reports prepared and submitted to the Independent Accounting Firm by Seller and Buyer and (ii) the determinations by the Independent Accounting Firm shall be based solely on such reports submitted by Seller and Buyer and the basis for Seller’s and Buyer’s respective positions. Seller and Buyer agree to enter into an engagement letter with the Independent Accounting Firm containing customary terms and conditions for this type of engagement. The parties shall use their commercially reasonable efforts to cooperate with and provide information and documentation, including work papers, to assist the Independent Accounting Firm. Any such information or documentation provided by either party to the Independent Accounting Firm shall be concurrently delivered to the other party, subject, in the case of the Independent Accounting Firm’s work papers, to such other party entering into a customary release agreement with respect thereto. Neither party shall disclose to the Independent Accounting Firm, and the Independent Accounting Firm shall not consider for any purposes, any settlement discussions or settlement offers made by either party with respect to any objection under this Section 1.2. The determinations by the Independent Accounting Firm as to the item or items in dispute shall be in writing and shall be final, binding and conclusive for all purposes of determining the Closing Benefits Accounts and shall have the same effect for all purposes as if such determinations had been embodied in a final judgment, entered by a court of competent jurisdiction, and either party may petition a court of competent jurisdiction in accordance with Section 9.5 to reduce such decision to judgment. The fees, costs and expenses of retaining the Independent Accounting Firm shall be borne 50% by Seller and 50% by Buyer. Following the resolution of all disputed items (or, if there is no dispute, promptly after the parties reach agreement on the Closing Benefits Accounts), Seller shall revise the Closing Benefits Accounts to reflect the resolution of any disputed items (as so revised, the “Final Closing Benefits Accounts”) and shall deliver a copy thereof to Buyer. (e) With respect to the adjustment to the Preliminary Benefits Accounts, if any, contained in the Final Closing Benefits Accounts, such adjustment shall be settled in accordance with Section 4.6. Section 1.3 Closing. The closing of the purchase and sale of the Shares contemplated by this Agreement (the “Closing”) shall take place at 10:00 a.m., New York City time, at the offices of Debevoise & Plimpton LLP, 66 Hudson Boulevard, New York, New York 10001 (or such other place as Seller and Buyer may agree in writing) (a) on the date that is the last Business Day of the calendar month during which the last of

the conditions set forth in Article 6 to be so satisfied or waived has been so satisfied or waived in accordance with this Agreement (other than those conditions that by their terms are to be satisfied by actions taken at the Closing, but subject to the satisfaction or waiver of such conditions at the Closing) (the “Condition Satisfaction”); provided that, if the Condition Satisfaction occurs fewer than ten (10) Business Days prior to the last Business Day of the calendar month during which the Condition Satisfaction occurs, then the Closing shall take place on the date that is the last Business Day of the calendar month immediately following the calendar month in which the Condition Satisfaction occurs, or (b) at another date, time or place that is mutually agreed to in writing by Seller and Buyer. The date on which the Closing takes place shall be the “Closing Date.” At the Closing: (a) Seller shall deliver to Buyer: (i) free and clear of any Liens, (A) for Shares that are in certificated form, if any, share certificates (or, in relation to certificates that are missing or lost, an affidavit of lost share certificate, in a form and substance reasonably acceptable to Buyer), evidencing the Shares owned by Seller to the extent that such Shares are in certificated form, duly endorsed in blank or accompanied by a stock power duly executed in blank in proper form to transfer, by Seller, and (B) for Shares that are in uncertificated form (or are in certificated form but not bearing), if any, an instrument of transfer in respect of the Shares held by Seller, in form and substance reasonably acceptable to Buyer, executed by Seller; (ii) the certificate referred to in Section 6.2(c); (iii) written resignations of each of the directors, managers and officers, as applicable, of the Company, effective as of the Closing; (iv) an executed IRS Form W-9; and (v) each Ancillary Agreement to which it is a party. (b) Buyer shall deliver to Seller: (i) payment, by wire transfer to a bank account designated in writing by Seller (such designation to be made at least three (3) Business Days before the Closing Date), of immediately available funds in an aggregate amount equal to the Purchase Price; and (ii) the certificate referred to in Section 6.3(c); and (iii) each Ancillary Agreement to which it is a party.

Section 1.4 Withholding. Each of Buyer and the Company (and any agent thereof) shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement to Seller such amounts as Buyer or the Company (and any agent thereof), as applicable, is required to withhold or deduct under the Code or any provision of applicable state, local or foreign Law with respect to the making of such payment; provided, however, that prior to making any such deduction or withholding on any amount (other than withholding as a result of any Person’s failure to deliver the documents described in Section 1.3(a)(iv)), Buyer shall use its commercially reasonable efforts to provide Seller with notice of intent to make such deduction or withholding and shall work in good faith to avoid or minimize the need to make such deduction or withholding to the extent permitted by applicable Law. To the extent that amounts are so withheld by Seller or the Company (or any agent thereof) and remitted to the appropriate Governmental Authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the applicable payee in respect of whom such deduction and withholding were made by Buyer or the Company (or any agent thereof), as applicable. ARTICLE 2 Representations and Warranties of Seller Except as set forth in the Seller Disclosure Letter, Seller represents and warrants to Buyer as of the date hereof and as of the Closing Date as follows: Section 2.1 Corporate Status. The Company is a corporation duly organized, validly existing and in good standing under the Laws of its jurisdiction of incorporation and has all requisite corporate power and authority to own, lease and operate its property and assets and to carry on its business as now conducted. Seller is a corporation duly incorporated, validly existing and in good standing under the Laws of its jurisdiction of incorporation. Except as set forth in Section 2.1 of the Seller Disclosure Letter, the Company is duly qualified to do business as a foreign corporation and is in good standing (where such concept is recognized) in all jurisdictions in which the property or assets owned, leased or operated by it, or the nature of the business conducted by it, is required to be so qualified or in good standing, except where the failure to be so qualified or in good standing would not reasonably be expected, individually or in the aggregate, to be material to the Company and its Subsidiaries, taken as a whole. Section 2.2 Corporate and Governmental Authorization. (a) Seller has all requisite corporate power and authority to execute and deliver this Agreement and the Ancillary Agreements and, subject to obtaining the Required Shareholder Approval, to perform its obligations hereunder and thereunder and to consummate the transactions contemplated hereby and thereby. The execution and delivery of this Agreement and the Ancillary Agreements by Seller, the performance of

Seller’s obligations hereunder and thereunder and the consummation of the transactions contemplated hereby and thereby have been duly authorized by all requisite corporate action of Seller, except for obtaining the Required Shareholder Approval. At a meeting duly called and held, prior to the execution of this Agreement, at which all directors of Seller were present and voting in favor, the Seller Board duly adopted resolutions (which, as of the date of this Agreement, have not been rescinded, modified or withdrawn in any way) (i) declaring that this Agreement and the Ancillary Agreements and the consummation of the transactions contemplated hereby and thereby are expedient and in the best interests of Seller and its stockholders, and declared it advisable and in Seller’s best interests to enter into this Agreement and to perform its obligations hereunder and thereunder, (ii) approving (A) the execution and delivery of this Agreement by Seller and the consummation of the transactions contemplated hereby, and (B) the performance by Seller of its covenants and other obligations hereunder on the terms and subject to the conditions set forth herein, subject to the Required Shareholder Approval and (iii) recommending that the transactions contemplated by this Agreement be approved by Seller’s stockholders in accordance with the DGCL. The Seller Board has directed that such resolutions be submitted to Seller’s stockholders for their approval at the Seller Shareholders Meeting. Seller has duly executed and delivered this Agreement on the date hereof and will have duly executed and delivered the Ancillary Agreements that are required to be executed and delivered by Seller on the Closing Date by this Agreement. This Agreement constitutes, and each such Ancillary Agreement to which Seller is a party when so executed and delivered constitutes or will constitute, as applicable, the legal, valid and binding obligation of Seller enforceable against Seller in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, reorganization, insolvency, fraudulent conveyance, moratorium, receivership or similar Laws relating to or affecting creditors’ rights generally and by general principles of equity (whether considered at law or in equity) (collectively, the “Enforceability Exceptions”). (b) Except as set forth in Section 2.2(b) of the Seller Disclosure Letter, or as may result from any facts or circumstances solely relating to Buyer or its Affiliates (as opposed to any other third party), the execution and delivery of this Agreement and the Ancillary Agreements by Seller and the performance of its obligations hereunder and thereunder and the consummation of the transactions contemplated hereby and thereby require no action by or in respect of, or filing with, any Governmental Authority other than any actions or filings under Laws the absence of which would not reasonably be expected, individually or in the aggregate, to materially impair the ability of Seller to consummate the transactions contemplated hereby or thereby. (c) The affirmative vote (in person or by proxy) of the holders of a majority of the voting power of Seller Common Stock then outstanding at the Seller Shareholders Meeting (the “Required Shareholder Approval”) in favor of the approval of the transactions contemplated by this Agreement and the Ancillary Agreements is the only

vote of, or approval by, the holders of any class or series of share capital of Seller or any of its Affiliates that is necessary to approve the transactions contemplated by this Agreement and the Ancillary Agreements. Section 2.3 Non-Contravention. Provided that all consents, approvals, authorizations and other actions described or referenced in Section 2.2 have been obtained or taken, except as may result from any facts or circumstances solely relating to Buyer or its Affiliates (as opposed to any other third party), the execution and delivery of this Agreement and the Ancillary Agreements by Seller and the performance of its obligations hereunder and thereunder and the consummation of the transactions contemplated hereby and thereby do not (a) conflict with or breach any provision of the Organizational Documents of Seller, the Company or any of its Subsidiaries, (b) assuming compliance with the matters referred to in Sections 2.2(b) and Section 2.2(c), conflict with, constitute (with or without due notice or lapse of time or both) a default under or breach any provision of any Law or Governmental Order, in each case applicable to any of Seller or its Subsidiaries or to which any of their respective properties or assets are subject, (c) except as set forth in Section 2.3 of the Seller Disclosure Letter, require any consent of or other action by any Person under, constitute a default or an event that, with or without notice or lapse of time or both, would constitute (with or without the lapse of time or both) a default under, or give rise to any Person’s right of termination, cancellation, acceleration, modification or other change of any right or obligation of such Person, or to a loss of any benefit to which any of Seller or its Subsidiaries is entitled under, or require any notice under, any provision of any Contract or Permit affecting the Company or its Affiliates or (d) result in the creation or imposition of any Lien (other than Permitted Liens) on any equity interests, assets or properties of the Company and its Subsidiaries, except in each case of clauses (b), (c) and (d), as would not reasonably be expected, individually or in the aggregate, to be material to the Company and its Subsidiaries, taken as a whole. Section 2.4 Capitalization; Title to Shares. (a) The authorized capital stock of the Company consists of 40,000,000 shares of common stock, par value $2.50 per share, of which only the Shares are issued and outstanding, and, as of the date hereof, 285,000 Auction Market Preferred Shares (the “AMPS”), of which 4,596 are issued and outstanding (the “Outstanding AMPS”). The Shares and the Outstanding AMPS have been duly authorized and validly issued, are fully paid and nonassessable and were not issued in violation of any applicable securities Laws or any option, right of first refusal, preemptive right, subscription right or any similar right under any provision of applicable Law, the Organizational Documents of any of the Company or its Subsidiaries or any other agreement to which any of the Company or its Subsidiaries is a party or otherwise bound. Seller owns the Shares, beneficially and of record, free and clear of any Liens other than Permitted Liens.

(g) Except as set forth in Section 2.15(g) of the Seller Disclosure Letter or as required by Section 4.6, the execution and delivery of this Agreement by Seller and the consummation of the transactions contemplated by this Agreement will not (alone or in combination with any other event) (i) result in any new compensation or benefit or an increase in the amount of compensation or benefits, or the acceleration of the vesting, funding or timing of payment of any compensation or benefits payable to or in respect of any Business Employee or other current or former employee or other service provider of the Company or any of its Subsidiaries, (ii) result in any liability of the Company and its Subsidiaries that is not assumed, incurred or paid for by Seller or another of its Subsidiaries for any compensation or benefits to any current or former Business Employee or other current or former employee or other service provider of the Company or any of its Subsidiaries or (iii) restrict the ability of the Company to merge, amend or terminate any Company Benefit Plan, (iv) require a contribution by the Company or any of its Subsidiaries to any Company Benefit Plan, (v) result in the forgiveness of any employee or service provider loan or (vi) result in any “excess parachute payment” (as defined in Section 280G(b)(1) of the Code).

(h) Each Seller Benefit Plan and Company Benefit Plan that constitutes in any part a “nonqualified deferred compensation plan” (as defined under Section 409A(d)(1) of the Code) subject to Section 409A of the Code and in which a Business Employee or, except as would not result in any liability to the Company or any of its Subsidiaries, other current or former employee or other service provider of the Company or any of its Subsidiaries participates has, in respect of such Business Employees, or other service providers, been operated and administered in all material respects in operational compliance with, and is in all material respects in documentary compliance with, Section 409A of the Code and all IRS guidance promulgated thereunder, and no amount under any such plan, agreement or arrangement is, has been or would reasonably be expected to be subject to any additional Tax, interest or penalties under Section 409A of the Code.

As of the date hereof, none of the Company or its Subsidiaries has received written notice that the obligor under any of the Investment Assets is in default (or written notice of any events which, with notice or lapse of time or both, would constitute a default) of any payment on any of the bonds, notes, mortgages, debentures and other evidence of indebtedness with respect to the Investment Assets, or any payment of principal, distributions, interest, dividends or other material payment or performance obligation thereunder, in each case, in any material respect. As of the Closing, none of the Company, its Subsidiaries or any other Person on behalf of the Company or its Subsidiaries will have taken, or will have omitted to take, any action which would cause any of the Investment Assets owned by the Company and its Subsidiaries as of the Closing to be subject to any valid offset, defense or counterclaims against the right of such entity to enforce the terms of such assets, in each case, in any material respect.

The execution and delivery of the Equity Commitment Letter and the consummation of the transactions contemplated thereby have been duly and validly authorized by all necessary action on the part of Buyer and, to the Knowledge of Buyer, each other party thereto.

(b) Without limiting the foregoing, each of Seller and Buyer shall use, and shall cause their respective Affiliates and Control Persons, as applicable, to use, reasonable best efforts to avoid any impediments under any applicable Law that may be asserted by, or Governmental Order that may be entered by, any Governmental Authority with respect to this Agreement or the transactions contemplated hereby or by the Ancillary Agreements so as to enable the Closing to occur as promptly as practicable, including taking or refraining from taking or agreeing to take, or causing its Affiliates and Control Persons to take or refrain from taking any actions (i) as reasonably required or requested by any Governmental Authority or (ii) necessary to avoid or eliminate any restriction or limitation, or to satisfy any condition or requirement reasonably imposed by any Governmental Authority, in each case to (A) obtain all Governmental Approvals necessary, proper or advisable to consummate the transactions contemplated by this Agreement and the Ancillary Agreements and secure the expiration or termination of any applicable waiting period under the HSR Act, (B) resolve any objections that may be asserted by any Governmental Authority with respect to the Closing or any other transaction contemplated hereby or by any Ancillary Agreement and (C) prevent the entry of, and have vacated, lifted, reversed or overturned, any Governmental Order that would prevent, prohibit, restrict or delay the consummation of the Closing or any other transaction contemplated hereby; provided that, notwithstanding anything to the contrary contained in Section 4.3 or elsewhere in this Agreement, none of Buyer or any of its Affiliates or Control Persons shall be required to (x) take any action or commit to taking any action that would constitute, or otherwise agree to, a Burdensome Condition or (y) commence any Litigation against any Governmental Authority. (c) In furtherance of and without limiting the generality of the foregoing, (i) Buyer and its Control Persons shall file, or cause to be filed, a Form A Statement

Regarding the Acquisition of Control of a Domestic Insurer with respect to the Company or a disclaimer of “affiliation” with respect to the Company, if appropriate, together with all required applicants, together with all exhibits, affidavits and certificates with the Wisconsin Office of the Commissioner of Insurance within fifteen (15) Business Days of the date hereof, (ii) Seller and Buyer shall file a notification and report form pursuant to the HSR Act with the Federal Trade Commission and the Antitrust Division of the United States Department of Justice with respect to the Closing and the other transactions contemplated hereby and requesting early termination of the waiting period under the HSR Act, within fifteen (15) Business Days of the date hereof, (iii) Buyer shall file, or cause to be filed, any pre-acquisition notifications on “Form E” or similar market share notifications to be filed in each jurisdiction where required by applicable Laws with all required applicants, within fifteen (15) Business Days of the date hereof and (iv) Buyer shall file a notification under s178 of the FSMA with the PRA within fifteen (15) Business Days of the date hereof. Each party shall be responsible for the costs that such party incurs in connection with such registrations filings and notices and obtaining any such permits, orders, or other consents, approvals or authorizations of Governmental Authorities (it being understood that Buyer shall be responsible for filing fees in connection with the filing and notification required under the HSR Act). All filing fees payable in connection with the foregoing shall be borne by Buyer. (d) Seller, on the one hand, and Buyer, on the other hand, agree that they shall consult with one another with respect to the obtaining of all Governmental Approvals necessary, proper or advisable to consummate the transactions contemplated by this Agreement and the Ancillary Agreements and each of them shall keep the other apprised on a prompt basis of the status of matters relating to such Governmental Approvals. Seller and Buyer shall have the right to review in advance, subject to redaction of personally identifiable, commercially sensitive or legally privileged information, and, to the extent practicable, and subject to any restrictions under applicable Law each shall consult the other on, any filing made with, or written materials submitted to, any Governmental Authority or any third party in connection with the transactions contemplated by this Agreement and the Ancillary Agreements, and each party agrees to in good faith consider and reasonably accept comments of the other party thereon. Seller and Buyer shall promptly furnish to each other copies of all such filings and written materials after their filing or submission, in each case subject to applicable Laws and subject to redaction of personally identifiable or legally privileged information. (e) Subject to restrictions under applicable Law, Seller and Buyer shall promptly (and in no event later than two (2) Business Days after receipt) advise each other upon receiving any non-ministerial communication from any Governmental Authority whose Governmental Approval is required for consummation of the transactions contemplated by this Agreement and the Ancillary Agreements, including, subject to redaction of personally identifiable or legally privileged information, promptly furnishing each other copies of any written or electronic communications, and shall

promptly advise each other when any such communication causes such party to believe that there is a reasonable likelihood that any such consent or Governmental Approval will not be obtained or that the receipt of any such Governmental Approval will be materially delayed or conditioned. (f) Neither Seller nor Buyer shall, and they shall cause their respective Affiliates not to, permit any of their respective Control Persons, partners, members, stockholders or any other Representatives to participate in any live or telephonic meeting (other than non-substantive scheduling or administrative calls or meetings initiated by the relevant Governmental Authority and not scheduled in advance; provided that, the party participating in such meeting shall promptly (and in no event later than one (1) Business Day) apprise the other party to the fact of such meeting and any substantive discussions that occurred during such meeting) with any Governmental Authority in respect of any filings, investigation or other inquiry relating to the transactions contemplated by this Agreement or the Ancillary Agreements unless it consults with the other in advance and, to the extent permitted by applicable Law and by such Governmental Authority, gives the other party the opportunity to attend and participate in such meeting. (g) Each of Seller and Buyer shall use reasonable best efforts promptly to: (i) provide (where in its possession or control) or procure the provision by its Affiliates of (where in the possession or control of its Affiliate or Affiliates) such information and such assistance to the other party to the extent reasonably required or requested in connection with ensuring that all Governmental Approvals necessary, proper or advisable to consummate the transactions contemplated by this Agreement are obtained; (ii) provide (where in its possession or control) or procure the provision by its Affiliates of (where in the possession or control of its Affiliate or Affiliates) responses or assistance to reasonable requests for further information or assistance by a relevant Governmental Authority and (iii) take such steps or refrain from taking such steps (where in its possession or control) or procure that its Affiliates take such steps or refrain from taking such steps (where in the possession or control of its Affiliate or Affiliates) as are necessary in order to satisfy any condition, requirement, request or restriction of a Governmental Authority that requires action on the part of such party in order to satisfy it. No person shall be required to provide any information the disclosure of which is not permitted under applicable Law, and the foregoing obligations shall be subject to the limitation on Burdensome Condition as set forth above. (h) Notwithstanding anything in this Agreement to the contrary, no party shall be obliged under this Section 4.3 to disclose to any other party, or any of their advisers, materials or information containing or comprising any personally identifiable or personal financial or legally privileged information, unless it is necessary to do so in order to ensure that all Governmental Approvals necessary, proper or advisable to consummate the transactions contemplated by this Agreement are obtained, in which case such

information shall be redacted as necessary or disclosed on a confidential outside counsel only basis (at the sharing party’s reasonable discretion). Section 4.4 Third-Party Consents; Shared Contracts. (a) Prior to the Closing, except as otherwise agreed by the parties, each party shall cooperate with the other and use commercially reasonable efforts to make or obtain the Third-Party Consents required to have been identified in Section 2.3 of the Seller Disclosure Letter (disregarding the materiality qualifier set forth in Section 2.3 of this Agreement); provided, that neither party shall be required to compromise any right or benefit, or commence or participate in any Litigation, in order to obtain any such Third- Party Consent, and the costs and expenses associated with obtaining such Third-Party Consents shall be borne 50% by Buyer and 50% by Seller, provided that Buyer shall not be responsible for any such costs in excess of $1,000,000 in the aggregate. (b) With respect to each Shared Contract, except for those identified and mutually agreed by the parties, each acting reasonably and in good faith, from and after the date of this Agreement through the earlier of (i) the date that is twelve (12) months following the Closing Date, and (ii) the termination or expiration of such Shared Contract, Seller shall, and shall cause its Affiliates to, use commercially reasonable efforts and cooperate with Buyer to the extent reasonably requested by Buyer to cause the counterparty to any Shared Contract to enter into a new agreement or to effect a partial assignment of the Shared Contract, on substantially the same terms and conditions as those set forth in the Shared Contract, with Buyer or the Company or any of its Subsidiaries with respect to the matters addressed by such Shared Contract that are related to the business of the Company and its Subsidiaries; provided, that the costs to Buyer, the Company and its Subsidiaries with respect to any new agreement or partially- assigned agreement for the contracted goods, services, assets, or other benefits shall not exceed the costs reasonably allocable to the actual volume or consumption of the contracted goods, services, assets, or other benefits by the Company and its Subsidiaries on a go-forward basis (irrespective of historical allocations or proportional usage between Seller and its Affiliates (excluding the Company and its Subsidiaries), on the one hand, and the Company and its Subsidiaries, on the other hand). Section 4.5 Further Assurances. (a) Seller and Buyer (i) shall execute and deliver, or shall cause to be executed and delivered, such documents and other papers and shall take, or shall cause to be taken, such further actions as may be reasonably required to carry out the provisions of this Agreement and the Ancillary Agreements and give effect to the transactions contemplated by this Agreement and the Ancillary Agreements, (ii) subject to Section 4.3, shall refrain from taking any actions that could reasonably be expected to impair, delay or impede the Closing, (iii) without limiting the foregoing, shall use their respective reasonable best efforts to cause all the conditions to the obligations of the other parties to

(b) Seller and Buyer shall keep each other reasonably apprised of the status of the matters relating to the completion of the transactions contemplated hereby, including with respect to the satisfaction of the conditions set forth in Article 6. From time to time following the Closing, Seller and Buyer shall, and shall cause their respective Affiliates to, execute, acknowledge and deliver all reasonable further conveyances, notices, assumptions, releases and acquittances and such instruments, and shall take such reasonable actions as may be necessary or appropriate to make effective the transactions contemplated hereby and by the Ancillary Agreements as may be reasonably requested by the other party. Section 4.6 Employees and Employee Benefits. (a) Prior to the Closing, Seller shall, to the extent permitted by applicable Law, (i) transfer the personnel records, work visas, Accrued Vacation Days (along with all related accruals and subject to applicable Laws and any Seller obtaining any required employee consents) and all employment-related Contracts of the Business Employees who are not employed by the Company and its Subsidiaries to the Company and its Subsidiaries and (ii) transfer the employment, employment-related Contracts, and related liabilities, of all other employees of the Company and its Subsidiaries who are not Business Employees, to Seller or another of its Subsidiaries (other than the Company and its Subsidiaries), at Seller’s sole expense, such that, as of the Closing, the exclusive employees of the Company and its Subsidiaries shall be the Business Employees. (b) Except as otherwise expressly provided in this Section 4.6, (A) Seller and its Affiliates (other than the Company and its Subsidiaries) shall be solely responsible for and retain or assume all liabilities in respect of (1) any employees of the Company and its Subsidiaries who are not Business Employees, whenever incurred, and (2) any medical, dental, health, accident or disability claim under any Seller Benefit Plan, including to the extent that such liability or obligation relates to claims incurred pursuant to a Seller Benefit Plan (whether or not reported or paid) on or prior to the Closing Date and to the extent not insured under a Company Benefit Plan and (B) Buyer’s applicable Affiliates (including the Company or its applicable Subsidiaries) and, as applicable, any Professional Employer Organization’s benefit plans in which Business Employees participate as of the Closing, at Buyer’s expense (a “PEO Plan”) shall be solely responsible for all liabilities in respect of Business Employees’ employment (and their dependents and beneficiaries) with Buyer and its Affiliates (including the Company and its Subsidiaries) following the Closing. For purposes of the foregoing, (i) a medical/dental claim shall be considered incurred when the services are rendered, the supplies are provided or medications are prescribed, and not when the condition arose and (ii) a disability claim shall be considered incurred on the date that the injury or illness

resulting in such claim occurs (and the recurrence of an illness or injury shall be treated as the initial incurrence of such illness or injury). (c) Effective as of the Closing Date, Seller shall, or shall cause its Affiliates to, take all actions necessary so that the Continuing Business Employees (as defined below) shall cease to be active participants in each Seller Benefit Plan that is not a Company Benefit Plan, and remove the Company and its Subsidiaries as participating employers in any such Seller Benefit Plan. Except as otherwise expressly provided for in this Section 4.6 Seller and its Affiliates (other than the Company and its Subsidiaries) shall retain the sponsorship of and shall be solely responsible for any and all liabilities with respect to all Seller Benefit Plans that are not Company Benefit Plans, including the responsibility for complying with the requirements of Section 4980B of the Code with respect to any “M&A qualified beneficiary” as that term is defined in Treasury Section 54.4980B-9. Seller shall bear and hold Buyer and the Company and its Subsidiaries harmless against one-third, and Buyer shall cause the Company to bear and hold Seller harmless against two-thirds, of all Losses arising out of or resulting from the establishment, documentation, administration, modification or termination of retiree or post-termination health or welfare benefit plans prior to the Closing Date, including any Litigation or other disputes arising with respect thereto (with any such Litigation or other dispute being controlled by the Company). (d) Seller and Buyer hereby agree that any Business Employee who (i) as of the Closing Date is receiving or is entitled to receive short-term disability benefits and who subsequently becomes eligible to receive long-term disability benefits under a Seller Benefit Plan that is not a Company Benefit Plan, or (ii) as of the Closing Date is receiving or is entitled to receive long-term disability benefits under a Seller Benefit Plan that is not a Company Benefit Plan, shall become eligible or continue to be eligible, as applicable, to receive long-term disability benefits under such Seller Benefit Plan unless and until such employee is no longer disabled. (e) For a period beginning on the Closing Date and continuing thereafter for twelve (12) months or such shorter period a Continuing Business Employee is employed by the Buyer or one of its Affiliates (including the Company and its Subsidiaries) (the “Continuation Period”), Buyer shall cause its applicable Affiliates (including, if applicable, the Company and its Subsidiaries) to provide Business Employees as of the Closing who continue employment with Buyer or one of its Affiliates (including the Company and its Subsidiaries) immediately following the Closing (the “Continuing Business Employees”) with (i) annual base salary or hourly wage rate (as applicable) that is at least equal to that provided to each such Continuing Business Employee immediately prior to the Closing, (ii) annual cash bonus opportunity that is at least equal to that provided to each such Continuing Business Employee immediately prior to the Closing and (iii) other employee benefits (excluding any nonqualified deferred compensation, change in control, transaction or retention bonuses, defined benefit

pension and post-employment or retiree health or welfare benefits, and further excluding any severance and long-term incentive or retention compensation (which are expressly covered elsewhere in this Section 4.6) (collectively, the “Excluded Benefits”)) either (x) under PEO Plans (as described in the following sentence) or (y) that are substantially comparable in the aggregate to those employee benefits provided to each such Continuing Business Employee immediately prior to the Closing under the Seller Benefit Plans listed on Section 2.15(a) of the Seller Disclosure Letter, in each case, subject to the same exclusions. Prior to the Closing Date, Seller shall arrange (in cooperation with Buyer) for a professional employer organization (“PEO”) to provide co-employment and employee- benefits related services to Continuing Business Employees on behalf of the Company during the Continuation Period, which shall include making certain PEO Plans (as selected by Seller, in consultation with Buyer) available to Continuing Business Employees effective as of the Closing Date. (f) Without limiting Section 4.6(b), with respect to any Continuing Business Employee whose employment is terminated by Buyer, the Company or any of their respective Affiliates during the Continuation Period immediately following the Closing Date, Buyer shall provide, or shall cause its Affiliates (including the Company) to provide, severance cash payments and subsidized COBRA or similar benefits to such Continuing Business Employee, which shall be determined and payable in accordance with either (i) the severance benefit plan or agreement maintained by Seller or any of its Affiliates (including the Company and its Subsidiaries) for the benefit of such Continuing Business Employee immediately prior to the Closing Date and included under the Seller Benefit Plans listed on Section 2.15(a) of the Seller Disclosure Letter or (ii) the severance benefit plan maintained for similarly-situated employees of Buyer and its Affiliates at the time of such Continuing Business Employee’s termination of employment, whichever is more favorable to the Continuing Business Employee, in each case taking into account all service with the Company, Seller, Buyer and their respective Affiliates in determining the amount of severance benefits payable and subject to applicable Laws (to the extent such service would have been taken into account under the corresponding Seller Benefit Plan). (g) For purposes of eligibility to participate, vesting and future vacation accrual under the employee benefit plans, programs and arrangements established or maintained by Buyer, the Company and their respective Subsidiaries, including PEO Plans, in which Continuing Business Employees may be eligible to participate after the Closing other than those providing Excluded Benefits (the “New Benefit Plans”), each Continuing Business Employee shall be credited with the same amount of service as such Continuing Business Employee was credited for the same purpose immediately prior to the Closing under the comparable Seller Benefit Plans in which such Continuing Business Employee participated immediately prior to the Closing Date; provided that such crediting of service shall not apply for any purposes under any Excluded Benefits or to the extent it would result in a duplication of benefits, compensation or coverage for the same period of service. In addition, and without limiting the generality of the foregoing,

for the plan year that includes the Closing Date, Buyer shall use commercially reasonable efforts to cause (i) with respect to any New Benefit Plans in which the Continuing Business Employees are eligible to participate following the Closing, each Continuing Business Employee to be immediately eligible to participate in such New Benefit Plans as of the Closing Date, without any waiting time, to the extent coverage under such New Benefit Plans replaces coverage under a similar or comparable Seller Benefit Plan in which such Continuing Business Employee participated immediately prior to the Closing Date (such plans, collectively, the “Old Benefit Plans”) and (ii) for purposes of each New Benefit Plan providing medical, dental, pharmaceutical and/or vision benefits to any Continuing Business Employee, all pre-existing condition exclusions and actively-at- work requirements of such New Benefit Plan to be waived for such Continuing Business Employee and his or her covered dependents, to the extent any such exclusions or requirements were waived, satisfied or were inapplicable under any similar or comparable Seller Benefit Plan, and (iii) any eligible expenses paid by and credited to such Continuing Business Employee and his or her covered dependents in the plan year that includes the Closing Date under the Old Benefit Plans that are group health plans to be taken into account under the corresponding New Benefit Plan that is a group health plan for purposes of satisfying the corresponding deductible, coinsurance and maximum out-of-pocket requirements applicable to such Continuing Business Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Benefit Plan. (h) Prior to the Closing, in connection with their transfer of employment, Seller shall transfer any vacation days, sick days and paid time off days accrued but not yet taken by the Business Employees and the related accruals, to the Company and its Subsidiaries (the “Accrued Vacation Days”) for which payout is not required by applicable Law. In the event that any Business Employee is entitled under applicable Law to be paid for any Accrued Vacation Days, Seller or the applicable Subsidiary shall timely pay any required amounts to such Business Employee. (i) In accordance with Section 4.9, the Company and its Subsidiaries shall pay to Seller, no later than date of payment of the purchase price true-up under Section 1.2(c)(iii), the proportion of all salary, benefits and other compensation and costs and expenses (including associated employer share of payroll Taxes) of employees and independent contractors who are natural persons of the Company and its Subsidiaries accrued by Seller in the ordinary course of business consistent with past practices (and, except for any acceleration of Seller RSU Awards, Seller PSU Awards or awards outstanding under the Ambac UK Long Term Incentive Plan 2020 (the “AUK LTIP Awards”) as a result of the Closing, without any changes to account for the transactions contemplated by this Agreement) from the date hereof through the Closing Date (but excluding any such accruals in respect of (i) payments or benefits under any Company Benefit Plan that are not paid or provided prior to the Closing, (ii) if applicable, Seller RSU Awards and Seller PSU Awards that are assumed, continued or substituted pursuant

to Section 4.6(j), and (iii) amounts that constitute Company Payments, which shall be paid entirely by the Company and its Subsidiaries) in the proportion allocated to the Company under the Amended and Restated Expense Sharing and Cost Allocation Agreement, dated May 1, 2021 (the “Intercompany Allocation Agreement”). If Seller, the Company or any of their respective Subsidiaries is reimbursed or otherwise made whole for any such accrued costs or expenses, including through a reimbursement from any Affiliate or business or operating unit of Seller that is not the Company or any of its Subsidiaries, then such reimbursement or make-whole payment shall offset the corresponding accrued costs or expenses for purposes of this Section 4.6(i). Notwithstanding anything to the contrary in this Section 4.6(i), any accrued costs or expenses relating to any incentive arrangements (including any incentive bonuses and performance-vesting equity or equity-based awards, including any Seller RSU Awards and Seller PSU Awards that are not assumed pursuant to Section 4.6(j)) will be disregarded unless the terms and conditions of such arrangements are consistent in all material respects with corresponding arrangements for prior performance periods, and the determination of the achievement of applicable performance goals is done in the ordinary course of business consistent with past practices and without any discretionary adjustments that would increase the amount of the corresponding accrued costs or expenses, except that achievement of any applicable performance conditions will not take into account any performance as a result of any mergers or other acquisitions of the Seller or any of its Subsidiaries following the date hereof that increase applicable costs and expenses corresponding to the applicable arrangement by more than 20%. (j) Except as set forth on Section 4.6(j) of the Seller Disclosure Letter, at the Closing, the Buyer or the Company or their Affiliate immediately after the Closing (but not Seller) shall assume, continue or substitute for the Seller RSU Awards and Seller PSU Awards of Business Employees that have not vested as of the Closing Date in compliance with the requirements of Section 13 of the Seller Equity Plan. (k) Prior to the Closing, but effective on or as soon as administratively practicable following the Closing Date, Seller shall cause a PEO Plan that is a defined contribution plan with a 401(k) feature (the “PEO 401(k) Plan”) to be made available for the benefit of the Continuing Business Employees in the U.S. As a result of the Closing, Business Employees shall be eligible to elect a distribution of their account balances from the Seller Benefit Plan that contains a 401(k) feature (“Seller 401(k) Plan”), and Seller shall cause the PEO 401(k) Plan to accept eligible rollover distributions of Continuing Business Employees’ account balances (including any loans) from the Seller 401(k) Plan. Effective as soon as administratively practicable following the Closing Date, Buyer shall cause on of its subsidiaries to establish a defined contribution plan for Continuing Business Employees in the UK that is tax-qualified under applicable Law in the UK. Prior to the Closing, Seller shall take all actions necessary to cause each Continuing Business Employee to become fully vested in his or her account balances or accrued

benefits under each Seller Benefit Plan (other than a Company Benefit Plan) intended to be qualified under Section 401(a) of the Code, effective as of the Closing Date. (l) [Intentionally omitted.] (m) Buyer agrees to comply in all material respects with the WARN Act as it relates to the Continuing Business Employees, during the ninety (90) days immediately following the Closing Date, and Seller agrees to comply in all material respects with the WARN Act as it relates to the Continuing Business Employees during the ninety (90) days immediately prior to the Closing Date. (n) Seller agrees that, notwithstanding the terms of any noncompetition, customer non-solicit or other restrictive covenant obligation between Seller or its Affiliates and a Business Employee, such Business Employee shall be permitted to provide services to Buyer and its Affiliates following the Closing, and neither Seller nor its Affiliates will seek to enforce the terms of any such restrictive covenant following the Closing with respect to such Business Employee’s services to Buyer and its Affiliates. Seller hereby assigns all such restrictive covenants, and any other restrictive covenants solely to the extent relating to the business of the Company and its Subsidiaries, to Buyer, and Buyer has the right, but not the obligation, to enforce such restrictive covenants. (o) No later than thirty (30) days prior to the Closing, (x) Seller shall use commercially reasonable efforts to make individual independent contractors who are then directly engaged by Seller or its Affiliates in connection with the business of the Company and its Subsidiaries available to Buyer for the purpose of allowing Buyer to interview each such contractor and determine the nature and extent of each such person’s continuation with the Company and its Subsidiaries following Closing, if any, and (y) Seller shall provide to Buyer contact information for third-party service providers then engaged by Seller or its Affiliates to provide contingent personnel with respect to the business of the Company and its Subsidiaries and reasonably cooperate in identifying and transferring such contingent work force to the extent requested by Buyer. (p) Non-Solicitation; No-Hire. In consideration of the payment of the Purchase Price and the other consideration provided by Buyer hereunder and as a condition precedent to Buyer’s consummation of the transactions contemplated by this Agreement and the Ancillary Agreements, during the period of two (2) years commencing on the Closing Date, Seller shall not, and shall cause its Affiliates and Representatives to not, directly or indirectly, solicit, hire or attempt to solicit or hire, any person who is a Business Employee, or otherwise induce or influence any such person to terminate their employment or engagement with the Company or any of its Subsidiaries, or to terminate or breach such Person’s employment agreement with Buyer or any of its Affiliates; provided, that the foregoing shall not be deemed to prohibit (i) general solicitations of employment, or recruitment efforts by recruitment agencies, not specifically directed by Seller or its Affiliates (directly or indirectly) toward employees or

service providers of the Company or its Subsidiaries and hiring any person who responds thereto, (ii) the employment of any person who is no longer employed by the Company or its Subsidiaries, so long as such person was not solicited or encouraged (directly or indirectly) by Seller, its Affiliate or any Person acting on their behalf to leave the employ of the Company or its Subsidiaries or (iii) the employment of any person who contacts Seller or its Affiliates on their own initiative without any direct or indirect solicitation or encouragement by Seller, its Affiliates or any Person acting on Seller’s behalf. (q) This Section 4.6 shall survive the Closing and shall be binding on all successors and assigns of Seller, Buyer (or, if applicable pursuant to this Section 4.6, its Affiliates, including the Company and its Subsidiaries). Seller and Buyer shall reasonably cooperate, and cause their respective Affiliates, including the Company and its Subsidiaries, to cooperate, as appropriate to carry out the provisions of this Section 4.6. Nothing set forth in this Section 4.6 shall confer any rights or remedies upon any employee or former employee of the Company and its Subsidiaries, any Continuing Business Employee, any of their dependents or beneficiaries or upon any other Person other than the parties hereto and their respective successors and assigns. Nothing in this Section 4.6 or this Agreement shall (i) constitute an amendment to, establishment or modification of any Seller Benefit Plan, any Company Benefit Plan or any other benefit or compensation, plan, program, policy, agreement or arrangement, (ii) limit the ability of Buyer or any of its Affiliates (including, following the Closing, the Company and its Subsidiaries) to amend, modify or terminate any Company Benefit Plan or any other benefit or compensation, plan, program, policy, agreement or arrangement or (iii) obligate Buyer or the Company to continue the employment (or any particular term or condition of employment) of any Continuing Business Employee for any specific period after the Closing Date. Section 4.7 Public Announcements. Buyer and Seller will cooperate in the preparation and contents of joint public announcements to be made upon the execution of this Agreement and the Closing. Except as required by applicable Law or the joint public announcements contemplated above, neither Buyer nor Seller shall make, or permit any of their Affiliates or Representatives to make, any public announcement in respect of this Agreement, the Ancillary Agreements or the transactions contemplated hereby and thereby without the prior written consent of the other party; provided, that the parties hereto may, without the prior written consent of the other party hereto, make such public announcement (a) as may be required by applicable Laws, stock exchange rules or Governmental Authority and, if practicable under the circumstances, after reasonable prior consultation with the other party hereto or (b) to enforce its rights under this Agreement. Notwithstanding anything in this Agreement to the contrary, Seller, Buyer and their respective Affiliates shall not be prohibited from disclosing any information concerning this Agreement or the transactions contemplated hereby (i) to auditors or ratings agencies; provided, that such auditors or ratings agencies are made aware of the provisions of this Section 4.7, (ii) to an adviser for the purpose of advising in connection

with the transactions contemplated by this Agreement; provided, further, that such advisor is made aware of the provisions of this Section 4.7 or (iii) to the extent that the information has been made public by, or with the prior consent of, the other party. Section 4.8 Insurance. Buyer acknowledges and agrees that, from and after the Closing Date, the Company, its Subsidiaries and the Assets shall cease to be insured by any insurance policies or any self-insured programs of Seller or Seller’s Affiliates (other than the Company and its Subsidiaries). With respect to events or circumstances relating to the business of the Company and its Subsidiaries that occurred or existed prior to the Closing Date and that are covered by occurrence-based third party liability insurance policies of Seller or its Affiliates, Buyer may request Seller or its Affiliates to make claims under such policies and to remit to Buyer the net proceeds of any recoveries in respect of such claims, provided, that Buyer (a) agrees to reimburse Seller or its Affiliates for any increased costs incurred by Seller or its Affiliates as a result of such claims, including any retroactive or prospective premium adjustments associated with such coverage and (b) shall not have such right to the extent that such claims are covered by insurance policies of Buyer or its Affiliates. As of the second anniversary of this Agreement, Buyer’s right pursuant to the immediately preceding sentence shall automatically expire. Section 4.9 Intercompany Accounts and Agreements; Company Payments. (a) Except as otherwise provided in this Agreement or the Ancillary Agreements: (i) Seller shall, and shall cause its Affiliates to, take such actions and make such payments as may be necessary so that as of immediately prior to the Closing, the Company and its Subsidiaries, on the one hand, and Seller and its Affiliates (other than the Company and its Subsidiaries), on the other hand, settle, discharge, offset, pay, repay, terminate or extinguish in full all Intercompany Accounts; provided that this Section 4.9(i) shall not apply to the Settlement Agreement; and (ii) Except as set forth on Section 4.9 of the Seller Disclosure Letter, all Intercompany Agreements to which the Company or any of its Subsidiaries is a party shall be terminated in respect of the Company or such Subsidiary, and the Company and such Subsidiary, as the case may be, shall be discharged without any further liability or obligation thereunder, effective immediately prior to the Closing. (b) Prior to the Closing, Seller shall promptly after discovery thereof notify Buyer of any payment, transaction, commitment or agreement by the Company or its Subsidiaries that has occurred after the date hereof which is reasonably expected to constitute a Company Payment.

(c) For the avoidance of doubt, the Company and its Subsidiaries will, from March 31, 2024 through the Closing Date, continue to be entitled to amounts from Seller and its Affiliates (other than the Company and its Subsidiaries) for cost reimbursement, expense sharing and other similar amounts determined consistent with historical practices. Section 4.10 D&O Indemnification; Insurance. Prior to the Closing, Seller shall acquire, at Seller’s sole cost and expense, a director and officer liability run-off policy or extended reporting coverage (i.e., “tail coverage”), which shall provide coverage for a period of six (6) years commencing immediately after the Closing for the individuals who were officers or directors of the Company or any of its Subsidiaries prior to the Closing comparable to the coverage provided as of the date hereof under the policy or policies maintained by or for the Company or any of its Subsidiaries for the benefit of such individuals. Section 4.11 Investment Assets. Without limiting Section 4.1, from the date hereof to the Closing Date, Seller shall cause the Insurance Companies to manage the Investment Assets in the ordinary course of business consistent with past practice, the Investment Guidelines and the Interim Asset Allocation Guidelines. From the date hereof until the Closing, Seller shall, within twenty (20) days following the end of each calendar month from the date hereof until the Closing, deliver to Buyer, (i) a list of each Investment Asset held by the Insurance Companies, (ii) a list of each Investment Asset held by the Insurance Companies that was sold or otherwise disposed of during the preceding month, the reason for such sale or disposition (which shall be consistent with the second sentence of this Section 4.11), and a description of the original cost and tax basis of such sold Investment Assets and (iii) a list of the Investment Assets acquired during the preceding month.

After the date hereof and prior to Closing, at either party’s request, the parties shall discuss and consider in good faith entering into one or more investment advisory agreements with American Acorn Services, LLC or a similar Affiliate of Buyer pursuant to which such entity will provide

investment advisory services to the Company; provided that nothing in this sentence shall relieve Buyer of its obligations under Section 4.3. Section 4.12 No Solicitation. (a) From and after the date of this Agreement until the earlier of the Closing or the valid termination of this Agreement in accordance with Article 7, and except as otherwise specifically provided for in this Agreement, Seller shall not, and shall cause its Subsidiaries not to, and shall cause its and its Subsidiaries’ officers, directors, employees, agents, consultants or professional advisors (“Representatives”) or other Affiliates not to, directly or indirectly, (i) solicit, initiate or knowingly encourage or facilitate the making of any Company Acquisition Proposal or any inquiry, proposal, request or offer which constitutes, or would reasonably be expected to lead to, or result in, a Company Acquisition Proposal, (ii) participate in any negotiations regarding, or furnish to any Person (other than Buyer, its Affiliates and their respective Representatives) any nonpublic information relating to the Company and any of its Subsidiaries, in connection with or related to any Company Acquisition Proposal or potential Company Acquisition Proposal, (iii) enter into any letter of intent, stock purchase agreement, merger agreement, asset purchase agreement or other agreement providing for a Company Acquisition Proposal (other than an Acceptable Confidentiality Agreement) (each an “Alternative Acquisition Agreement”), (iv) approve or authorize, or cause or permit the Company or any of its Subsidiaries to enter into, any agreement to reimburse any third party for costs, expenses or other liabilities incurred in connection with making (or evaluating for the purpose of making) a potential Company Acquisition Proposal, (v) grant any waiver, amendment or release under any “standstill” or confidentiality agreement or fail to enforce the terms of any such “standstill” or similar provision of any confidentiality (unless with respect to this clause (v) the Seller Board determines in good faith, after consultation with Seller’s outside financial advisors and outside legal counsel, that failure to take such action would be inconsistent with its fiduciary duties under applicable Laws, and if such action is so taken, shall provide the same release, amendment or waiver under the standstill in the Confidentiality Agreement) or (vi) resolve, commit or agree to do any of the foregoing. Promptly after execution of this Agreement, Seller shall, and shall cause each of its Subsidiaries to, and shall direct its and its Subsidiaries’ Representatives to, immediately cease any existing discussions or negotiations with any Person with respect to a Company Acquisition Proposal. (b) Notwithstanding the limitations set forth in Section 4.12(a) but subject to compliance with the other provisions of this Section 4.12, if, at any time prior to, but not after, the receipt of the Required Shareholder Approval (the “Alternative Acquisition Period”), Seller receives a Company Acquisition Proposal that the Seller Board determines in good faith, after consultation with Seller’s outside financial advisors and outside legal counsel, and based on information then available, is or would reasonably be expected to lead to a Superior Proposal, then Seller may, in response to such Company

Acquisition Proposal, furnish nonpublic information relating to the Company or any of its Subsidiaries to the Person or group (as defined pursuant to Section 13(d) of the Exchange Act) of Persons (or any of their Representatives) making such Company Acquisition Proposal and engage in discussions or negotiations with such Person or group (as defined pursuant to Section 13(d) of the Exchange Act) of Persons and their Representatives regarding such Company Acquisition Proposal; provided that (i) prior to furnishing any nonpublic information relating to the Company or any of its Subsidiaries to such Person or group (as defined pursuant to Section 13(d) of the Exchange Act) of Persons or their respective Representatives, the Company enters into an Acceptable Confidentiality Agreement with the Person or group (as defined pursuant to Section 13(d) of the Exchange Act) of Persons making such Company Acquisition Proposal and (ii) promptly (but not more than one (1) Business Day) after furnishing any such nonpublic information to such Person, Seller furnishes such nonpublic information to Buyer (to the extent such nonpublic information has not been previously so furnished to Buyer or its Representatives). Notwithstanding anything to the contrary contained in this Agreement, Seller and its Representatives may in any event (A) seek to clarify the terms and conditions of any Company Acquisition Proposal solely to determine whether such Company Acquisition Proposal constitutes or would reasonably be expected to lead to a Superior Proposal in accordance with this Section 4.12 and (B) inform a Person or group (as defined pursuant to Section 13(d) of the Exchange Act) of Persons that has made or, to the Knowledge of Seller, is considering making, a Company Acquisition Proposal of the terms of this Section 4.12. (c) Seller shall promptly (and in any event within one (1) Business Day) notify Buyer after receipt of any Company Acquisition Proposal, any inquiry or proposal that would reasonably be expected to lead to a Company Acquisition Proposal or any inquiry or request for nonpublic information relating to the Company and its Subsidiaries by any Person who has made or would reasonably be expected to make a Company Acquisition Proposal. Such notice shall indicate the identity of the Person making such Company Acquisition Proposal and the material terms and conditions of any such proposal or offer or the nature of the information requested pursuant to such inquiry or request. Thereafter, Seller shall keep Buyer reasonably informed, on a prompt basis (and in any event within one (1) Business Day), regarding any material changes to the status and material terms of any such proposal or offer (including any material amendments thereto or any material change to the scope or material terms or conditions thereof) and provide to Buyer as soon as practicable (and in any event within one (1) Business Day) after receipt thereof of any written indication of interest (or amendment thereto) (or if oral, written summaries of such indication of interests). (d) At no time after the date hereof may the Seller Board nor any committee thereof except in compliance with Section 4.12(e), (i) withhold, withdraw, amend, qualify or modify, or publicly propose to withhold, withdraw, amend, qualify or modify, the Seller Board Recommendation, in each case, in a manner adverse to Buyer (it being

understood that it shall be considered a modification adverse to Buyer if any Company Acquisition Proposal is publicly announced and the Seller Board fails to issue a public press release within ten (10) Business Days of such public announcement providing that the Seller Board reaffirms the Seller Board Recommendation) (or, if earlier, by the second (2nd) Business Day prior to the then-scheduled Seller Shareholders Meeting, if a Company Acquisition Proposal has been publicly disclosed at least three (3) Business Days prior to the then-scheduled Seller Shareholders Meeting); (ii) adopt, authorize, approve, agree to, accept, endorse or recommend, submit to vote of the stockholders of Seller or otherwise declare advisable (or propose to adopt, authorize, approve, agree to, accept, endorse or recommend, submit to vote of the stockholders of Seller or otherwise declare advisable) a Company Acquisition Proposal; (iii) fail to publicly reaffirm the Seller Board Recommendation within three (3) Business Days after Buyer so requests in writing; provided that Buyer may make any such request only once for each Company Acquisition Proposal and an additional time for each material amendment to any Company Acquisition Proposal; (iv) fail to include the Seller Board Recommendation in the Proxy Statement; or (v) formally resolve to effect, publicly announce an intention or resolution to, or agree to take any of the foregoing actions (any action described in clauses (i) through (v), a “Seller Board Recommendation Change”). (e) Notwithstanding anything to the contrary set forth in this Agreement, if Seller has received a bona fide written Company Acquisition Proposal prior to obtaining the Required Shareholder Approval that has not been withdrawn, and that the Seller Board has concluded in good faith (after consultation with its financial advisor and outside legal counsel) is a Superior Proposal that did not result from a breach of this Section 4.12, then the Seller Board may effect a Seller Board Recommendation Change with respect to such Superior Proposal; provided, however, that the Seller Board (or a committee thereof) shall not take such action unless (i) the Seller Board determines in good faith (after consultation with its outside legal counsel and outside financial advisors) that the failure to do so would be inconsistent with its fiduciary duties under applicable Law; (ii) Seller and its Subsidiaries, Affiliates and Representatives comply in all respects with the requirements of and their obligations under, and not have violated the provisions of, this Section 4.12; (iii) Seller shall provide Buyer at least five (5) Business Days’ (the “Superior Proposal Notice Period”) prior written notice of its intention to take such action, which notice shall, in reasonable detail, set forth the reasons therefor and the material terms and conditions of such Company Acquisition Proposal and include a copy of the most recent proposed definitive agreement related to such Company Acquisition Proposal, (iv) during such five (5) Business Day period, Seller and its Representatives shall negotiate in good faith with Buyer (to the extent Buyer desires to negotiate) regarding any revisions to the terms of the transactions contemplated hereby proposed by Buyer in response to such Superior Proposal and (v) at the end of the five (5) Business Day period described in the foregoing clause (iv) (or, in the event that the Company Acquisition Proposal has been materially revised or modified, at the end of the two Business Day period following the date of receipt of each such material revision or

modification, if later), the Seller Board determines in good faith (after consultation with its financial advisor and outside legal counsel) that such Company Acquisition Proposal continues to constitute a Superior Proposal (after taking into account in good faith any adjustments made by Buyer during the Superior Proposal Notice Period to the terms and conditions of this Agreement), and that the failure to take such action would be inconsistent with its fiduciary duties under applicable Laws. With respect to this Section 4.12(e), if there is any amendment, revision or change to the terms of any such Superior Proposal (including any revision to the amount of consideration Seller would receive as a result of the Superior Proposal), in each case, individually or in the aggregate, in a material respect and to the extent such proposal would no longer constitute a Superior Proposal in relation to Buyer’s proposal (after taking into account in good faith any adjustments made by Buyer during the Superior Proposal Notice Period to the terms and conditions of this Agreement), then for such amendment, revision or change Seller shall notify Buyer thereof in compliance with this Section 4.12(e) (including to provide any updated documentation or notices) by providing a new notice to Buyer, and the applicable Superior Proposal Notice Period shall be extended until at least three (3) Business Days after the time that Buyer receives such new notice from Seller of such amendment, revision or change, and Seller shall be required to comply again with the requirements of this Section 4.12(e) and the Seller Board shall not take any such action permitted under Section 4.12(e) prior to the end of such Superior Proposal Notice Period as so extended in accordance with the terms of this Section 4.12(e). (f) Seller agrees that any breach of this Section 4.12 by any Representative of Seller, including any financial advisor acting on behalf of Seller or its Affiliates, will be deemed to be a breach of this Section 4.12 by Seller. Seller will not authorize, direct or permit any of its Representatives, including any financial advisor, to breach this Section 4.12. (g) Nothing contained in this Agreement shall prohibit Seller or the Seller Board or any committee thereof from (i) taking and disclosing to shareholders of Seller a position or communication contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act (it being understood that any such communication to the shareholders of Seller shall not be deemed to be a Seller Board Recommendation Change) or (ii) making any disclosure or communication to shareholders of Seller that the Seller Board determines in good faith, based on the advice of its outside legal counsel, is required by the directors’ fiduciary duties or applicable Law. Section 4.13 Preparation of the Proxy Statement; Shareholders Meeting. (a) As promptly as reasonably practicable after the execution of this Agreement and, in any event prior to the date which is twenty (20) Business Days after the date of this Agreement (or such later date as Seller and Buyer may agree, in each case acting reasonably), Seller (with the assistance and cooperation of Buyer) shall prepare the

Proxy Statement and file it in preliminary form with the SEC. Subject to Section 4.12, the Seller Board shall submit the Seller Board Recommendation to Seller’s shareholders and shall include such recommendation in the Proxy Statement. Buyer shall provide to Seller all information concerning Buyer as may be reasonably requested by Seller in connection with the Proxy Statement and shall otherwise assist and cooperate with Seller in the preparation of the Proxy Statement and the resolution of any comments thereto received from the SEC. Each of Seller and Buyer shall promptly correct any information provided by it for use in the Proxy Statement if and to the extent such information shall have become false or misleading in any material respect. Each of Seller and Buyer shall notify the other promptly upon the receipt of any comments from the SEC and of any request by the SEC for amendments or supplements to the Proxy Statement or for additional information and shall supply the other with copies of all written correspondence between such party or any of its Representatives, on the one hand, and the SEC, on the other hand, with respect to the Proxy Statement. Each of Seller and Buyer shall use their respective reasonable best efforts to respond as promptly as reasonably practicable to any comments received from the SEC concerning the Proxy Statement and to resolve such comments with the SEC, and Seller shall use its reasonable best efforts to cause the Proxy Statement to be disseminated to its shareholders as promptly as reasonably practicable after the resolution of any such comments. Prior to the filing of the Proxy Statement (or any amendment or supplement thereto) or any dissemination thereof to Seller’s stockholders or responding to any comments from the SEC with respect thereto, Seller must provide Buyer with a reasonable opportunity to review and propose comments on such document or response, which Seller shall consider in good faith. (b) Subject to Section 4.13(a), Seller shall take all necessary actions in accordance with applicable Law, the Organizational Documents of Seller and the rules of New York Stock Exchange to duly call, give notice of, convene and hold a meeting of its shareholders (including any adjournment, recess, reconvening or postponement thereof, the “Seller Shareholders Meeting”) for the purpose of obtaining the Required Shareholder Approval, as soon as reasonably practicable after the SEC confirms that it has no further comments on the Proxy Statement. For the avoidance of doubt, unless this Agreement is validly terminated in accordance with Section 7.1, Seller shall submit this Agreement to the stockholders of Seller at the Seller Shareholders Meeting for the purpose of obtaining the Required Shareholder Approval even if the Seller Board has effected a Seller Board Recommendation Change. Subject to Section 4.12, Seller shall use its reasonable best efforts to obtain the Required Shareholder Approval. Notwithstanding anything to the contrary in this Agreement, Seller may, with the written consent of Buyer (such consent not to be unreasonably withheld, conditioned or delayed), adjourn, recess, reconvene or postpone the Seller Shareholders Meeting if Seller reasonably believes that (i) such adjournment, recess, reconvening or postponement is necessary to ensure that any required supplement or amendment to the Proxy Statement is provided to Seller’s shareholders within a reasonable amount of time in advance of the Seller Shareholders

Meeting, (ii) after consultation with Buyer, as of the time for which the Seller Shareholders Meeting is originally scheduled (as set forth in the Proxy Statement), (A) there will be an insufficient number of Seller Common Stock present (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Seller Shareholders Meeting or (B) there will be an insufficient number of proxies to obtain the Required Shareholder Approval or (iii) such adjournment, recess, reconvening or postponement is required by Law or a court or other Governmental Authority of competent jurisdiction in connection with any action, suit or proceeding in connection with this Agreement or the transaction contemplated by this Agreement or has been requested by the SEC or its staff.

The parties hereby waive, in any action for specific performance, the defense of adequacy of a remedy at law and the posting of any bond or other security in connection therewith. Notwithstanding the foregoing or any other provisions of this Agreement to the contrary, it is explicitly agreed that Seller shall be entitled to seek an injunction or injunctions or specific performance to enforce Buyer’s obligations to cause the Equity Financing to occur and to complete the Closing on the terms and conditions set forth in this Agreement if and only if (a) all of the conditions set forth in Sections 6.1 and 6.2 have been and remain satisfied or waived (other than those conditions which by their nature can only be satisfied at the Closing, but which conditions would be satisfied if the Closing were to occur), (b) Seller has delivered to Buyer a writing irrevocably confirming that as of the date on which the Closing should have occurred pursuant to Section 1.3, (i) all conditions set forth in Section 9.3 were satisfied, and all such conditions remain satisfied as of the date of the certification, or that Seller is irrevocably waiving any unsatisfied conditions in Section 6.3, (ii) Seller was ready, willing and able to consummate the Closing on the terms set forth in this Agreement on such date, and (iii) Seller will consummate the Closing if specific performance is granted and the Equity Financing is funded, and (c) Seller remains ready, willing and able to cause the Closing to occur. Section 9.12 Disclosure Letters. Any disclosure set forth in the Seller Disclosure Letter or Buyer Disclosure Letter with respect to any Section of this Agreement shall be deemed to be disclosed for purposes of other Sections of this

Agreement only to the extent that the applicability of the information disclosed to any such other Section of this Agreement is reasonably apparent on its face. Matters reflected in any Section of the Seller Disclosure Letter or the Buyer Disclosure Letter are not necessarily limited to matters required by this Agreement to be so reflected. Such additional matters are set forth for informational purposes and do not necessarily include other matters of a similar nature. No reference to or disclosure of any item or other matter in the Seller Disclosure Letter or the Buyer Disclosure Letter shall be construed as an admission or indication that such item or other matter is material or that such item or other matter is required to be referred to or disclosed in this Agreement. Without limiting the foregoing, no such reference to or disclosure of a possible breach or violation of any contract, Laws or Governmental Order shall be construed as an admission or indication that a breach or violation exists or has actually occurred. Section 9.13 Waiver of Conflicts; Attorney-Client Privilege. (a) Buyer (on behalf of itself and its controlled Affiliates) waives and will not assert, and agrees to cause the Company and its Subsidiaries to waive and not to assert, any conflict of interest arising out of or relating to the representation, after the Closing, of Seller or any of its Affiliates or any of their respective stockholders, officers, employees or directors (any such Person, a “Designated Person”) in any matter involving this Agreement or any other agreements or transactions contemplated thereby, by any legal counsel (including internal counsel and Debevoise & Plimpton LLP, “Seller Legal Counsel”) representing Seller, the Company, or any of its Subsidiaries in connection with this Agreement or any other agreements or transactions contemplated thereby (the “Current Representation”), including in any litigation or other dispute or proceeding between or among Buyer or its controlled Affiliates, the Company or any of its Subsidiaries, and any Designated Person, even though the interests of such Designated Person may be directly adverse to Buyer or its Affiliates or the Company and its Subsidiaries. (b) Buyer (on behalf of itself and its controlled Affiliates) acknowledges that all rights applicable to any attorney-client privileged communications between Seller Legal Counsel in connection with the Current Representation (the “Privileged Communications”) shall be retained solely by Seller (and not the Company and its Subsidiaries) and agrees that it will not, and will cause the Company and its Subsidiaries not to, assert any attorney-client privilege with respect to the Privileged Communications. Furthermore, Buyer will not, and will cause each of its controlled Affiliates (including, after Closing, the Company and its Subsidiaries) not to, use any Privileged Communications (or portion thereof) in a manner adverse to Seller or any of its Affiliates. (c) Accordingly, from and after the Closing, the Company and its Subsidiaries shall not have access to any Privileged Communications, or to the files of any Seller Legal Counsel in connection with the Current Representation to the extent related to the

Privileged Communications. Without limiting the generality of the foregoing, from and after the Closing, (i) Seller and its Affiliates shall be the sole holders of the attorney- client privilege with respect to the Current Representation, and the Company and its Subsidiaries shall not be holders thereof, and (ii) to the extent that files of Debevoise & Plimpton LLP or any other legal counsel currently representing any of the Company and its Subsidiaries in connection with the Current Representation (whether or not such legal counsel also represented Seller) constitute property of a client, only Seller and its Affiliates shall hold such property rights. Buyer (on behalf of itself and its controlled Affiliates) agrees that it would be impractical to remove all attorney-client communications from the records (including e-mails and other electronic files) of the Company and its Subsidiaries, and the failure to so remove such communications shall not be deemed to be a waiver of the attorney-client privilege with respect to such communications.
