The Associated Company or Immediate Relation (as the case may be) shall re-transfer its Shares to the Transferring Shareholder or (if so directed by the Transferring Shareholder) to another Associated Company or Immediate Relation of that Transferring Shareholder immediately if it ceases to be an Associated Company or an Immediate Relation of that Transferring Shareholder. 13.2 Put and Call Options 13.2.1 In this clause 13.2: (a) "Relevant Shares" means, (i) in relation to a Call Option: in respect of an Existing Shareholder, such number of Ordinary Shares as is equal to the lower of the total number of shares then held by Existing Shareholder, and: (A) 25% of such Existing Shareholder's Shares as at Completion; plus (B) any Unexercised Call Options; plus (C) in the event that following Completion there has been a new issue of Ordinary Shares (including by way of dividend) to the relevant Existing Shareholder other than pursuant to the MIP (such new Ordinary Shares issued to such Existing Shareholder being "Additional

Shares") prior to a relevant Option Exercise Date, such number of Additional Shares; and (ii) in relation to a Put Option: in respect of an Existing Shareholder, such number of Ordinary Shares as is equal to the lower of the total number of Ordinary Shares then held by Existing Shareholder and: (A) 25% of such Existing Shareholder's Shares as at Completion; plus (B) any Additional Shares issued prior to a relevant Option Exercise Date (excluding any Shares issued pursuant to the MIP), in each case, provided that if Additional Shares are issued they are subject to the Call Option and/or Put Option on the same basis as any Shares the Existing Shareholders have as at Completion. For example, (i) if such Additional Shares are issued the day immediately following Completion, then 25% of such Additional Shares are Relevant Shares at each relevant Option Exercise Date and (ii) if such Additional Shares are issued during 2026, then one-third of such Additional Shares are Relevant Shares at each Option Exercise Date from 2027 and provided further than no sweet equity shares issued pursuant to the MIP shall be subject to the Call Option and/or Put Option. (b) "Option Exercise Date" means (i) in respect of the Call Option, 31 March of every year from 2026, so long as there are Unexercised Call Options and (ii) subject to clauses 13.2.10 and 13.2.11, in respect of the Put Option, 31 March 2026, 31 March 2027, 31 March 2028, 31 March 2029 and, to the extent that there remain Unexercised Put Options, 31 March in each subsequent calendar year; (c) "Option Exercise Notice" means, in respect of a Call Option or a Put Option a notice submitted in writing to (i) the relevant Existing Shareholder (in respect of the Call Option) or (ii) Cirrata (in respect of the Put Option); and (d) "Option Exercise Period" means, in respect of a Call Option or a Put Option as at the relevant Option Exercise Date, a 30- day period beginning on the fifth Business Day following agreement or determination of Adjusted EBITDA for the full- year immediately preceding the relevant Option Exercise Date (the Adjusted EBITDA to be calculated in accordance with Schedule 5;

(e) "Unexercised Call Options" means, as at a relevant Option Exercise Date, such number of Shares held by an Existing Shareholder that could have been purchased pursuant to the exercise of a Call Option at a previous Option Exercise Date but had not been so purchased as a result of such Call Option not being exercised; and (f) "Unexercised Put Options" means, as at a relevant Option Exercise Date, such number of Shares held by an Existing Shareholder that could have been purchased pursuant to the exercise of a Put Option at a previous Option Exercise Date but had not been so purchased as a result of such Put Option not being exercised. 13.2.2 Subject to clause 13.3.2, each Existing Shareholder shall grant to Cirrata the option (the "Call Option”) to purchase from such Existing Shareholder, and Cirrata hereby grants to such Existing Shareholder the option (the “Put Option”) to require Cirrata to purchase from such Existing Shareholder, the Relevant Shares as at the relevant Option Exercise Date. Should any transfer of shares by Cirrata to any other member of the Ambac Group take place, then the Call Option and the Put Option may be transferred to such other member of the Ambac Group provided Cirrata and the Management Shareholders' Representative, each acting reasonably, agree terms such that the position of Cirrata and that of the Management Shareholders is not adversely affected, failing which Cirrata shall still remain liable for payments under the Call Option and the Put Option. 13.2.3 On or before the 31 January prior to the relevant Option Exercise Date, any of the Existing Shareholders and Cirrata shall notify the Board in writing if they wish the Board to prepare the Draft Documents in accordance with Schedule 5 in order to have an informed decision as to whether or not to exercise their Put Option or Call Option (as the case may be). If no such notice is given, then the Board shall not be required to prepare the Draft Documents, and no Put Option or Call Option may be exercised at the relevant Option Exercise Date. 13.2.4 Each Call Option in respect of an Existing Shareholder and an Option Exercise Date shall be exercisable in respect of some or all of the Relevant Shares (provided that the maximum number of Shares to be purchased pursuant to a Put Option and/or Call Option in respect of an Existing Shareholder and any Option Exercise Date shall not exceed the total number of Relevant Shares) by service of an Option Exercise Notice by Cirrata on the relevant Existing Shareholder during the Option Exercise Period. Once served, the Option Exercise Notice shall be irrevocable.

13.2.5 Each Put Option in respect of an Existing Shareholder and an Option Exercise Date shall be exercisable in respect of some or all of the Relevant Shares (provided that the maximum number of Shares to be purchased pursuant to a Put Option and/or Call Option in respect of an Existing Shareholder and any Option Exercise Date shall not exceed the total number of Relevant Shares) by service of an Option Exercise Notice by such Existing Shareholder on Cirrata during the Option Exercise Period. Once served, the Option Exercise Notice shall be irrevocable. 13.2.6 To the extent a Call Option in respect of an Existing Shareholder has been exercised in accordance with clause 13.2.4, BCC and the Management Shareholders will not be entitled to exercise the Put Option with respect to the amount of Relevant Shares subject to the Option Exercise Notice with regard to the relevant Option Exercise Date. 13.2.7 To the extent a Put Option has been exercised by an Existing Shareholder in accordance with clause 13.2.5, Cirrata will not be entitled to exercise the Call Option with respect to the amount of Relevant Shares subject to the Option Exercise Notice with regard to the relevant Option Exercise Date. 13.2.8 The purchase price of a share that is the subject of an exercised Put Option or Call Option as at a relevant Option Exercise Date shall be as follows: (a) in respect of BCC, any Management Shareholder who is not a Leaver and any Management Shareholder who is a Good Leaver other than within limbs (e) or (f) of the definition of Good Leaver, the purchase price per share shall be calculated in sterling on a fully diluted basis based on an aggregate equity value for 100% of the Shares (including any Shares that may be issued pursuant to the MIP, or, as appropriate for accounting for any MIP-related dilution) equal to (i) 16.0 x Adjusted EBITDA (as at the immediately preceding Accounting Reference Date) less (ii) Net Debt (as at the immediately preceding Accounting Reference Date) (it being noted that Net Debt is to be determined by reference to the consolidated Group excluding shareholdings in Subsidiaries' interest and, if it is negative, it shall be added to the calculation) plus (iii) the Working Capital Adjustment (as at the immediately preceding Accounting Reference Date) (it being noted that the Working Capital Adjustment is to be determined by reference to the consolidated Group excluding shareholdings in Subsidiaries' interest and, if it is negative, it shall deducted from the calculation), and any Leakage (as defined in the Share

Purchase Agreement) in respect of the relevant Shareholder (from the immediately preceding Accounting Reference Date to (and including) the Closing Date of the relevant Call Option or Put Options) shall be deducted from the aggregate Purchase Price payable to that Shareholder; (b) in respect of any Management Shareholder who is a Good Leaver within limbs (e) or (f) of the definition of Good Leaver, the purchase price shall be the lower of: (i) the purchase price calculated in accordance with clause 13.2.8(a); and (ii) the purchase price that would be calculated in accordance with clause 13.2.8(a) if Adjusted EBITDA were for the most recently completed financial year of the Company ending 31 December prior to the date the relevant Good Leaver’s employment terminated; and (c) in respect of any Management Shareholder who is a Bad Leaver, the purchase price shall be the amount that would have been calculated in accordance with clause 13.2.8(b) if the figure "16.0" were replaced by "10.0". 13.2.9 Completion of the sale and purchase of Relevant Shares pursuant to the exercise of a Put Option or a Call Option shall take place on the fifth Business Day following the relevant Option Exercise Date, subject to any Regulatory Extension (the "Closing Date"). At such completion: (a) Cirrata will pay to the relevant Existing Shareholder the aggregate purchase price as calculated in accordance with 13.2.8, such payment to be satisfied by: (i) (at Cirrata's election) procuring the issue of such shares of Ambac Stock to the relevant Existing Shareholder as is calculated as follows: Shares of Ambac Stock = C VWAP where: C = such part of the purchase price to be payable to the relevant Existing Shareholder in shares of Ambac Stock, up to a maximum amount equal to such Existing Shareholder's pro rata (by number of Ordinary Shares to be sold by such Existing Shareholder to the total number of Ordinary Shares to be sold by Existing Shareholders at such time) share of the lower of (A) 35% of the aggregate purchase price payable to all

Existing Shareholders and (B) the absolute cumulative value of four days of Ambac Stock traded, based on the average volume and VWAP traded during the 25 consecutive trading days prior to (but not including) the date of the Option Exercise Date (such determined price, the “Ambac Stock Price”); VWAP = the volume weighted average price in USD for a share of common stock in Ambac (as calculated by Bloomberg Financial LP using the function “AMBC US <Equity> VWAP”) for the period comprising the 25 consecutive trading days prior to (but not including) the date of the Option Exercise Date (such period the "Trading Period"); and (ii) the balance of such aggregate purchase price by payment in cash to such bank account of the Existing Shareholder as has been nominated to Cirrata in writing (it being understood that the sterling cash balance for a relevant Existing Shareholder is the excess of the aggregate purchase price (which is denominated in sterling) to be paid to the relevant Existing Shareholder over the sterling value of the aggregate Ambac Stock to be delivered to the relevant Existing Shareholder); (b) upon receipt of the aggregate purchase price, the relevant Existing Shareholder shall (i) deliver to Cirrata a stock transfer form and the original share certificate (or an indemnity for a lost share certificate in favour of the Company in such form as is reasonably acceptable to the Board) in respect of the transferring Relevant Shares and (ii) warrant to Cirrata that such Existing Shareholder (A) is the sole legal and beneficial owner of the transferring Relevant Shares free from any Encumbrances, (B) has the right to exercise all voting, economic and other rights over such transferring Relevant Shares and (C) has the right to transfer such Relevant Shares with full title guarantee and free from any Encumbrances. Cirrata undertakes to the Existing Shareholders that it will pay to each Existing Shareholder in respect of whom a Put Option or a Call Option has been exercised as of a relevant Option Exercise Date the same proportions of Ambac Stock and cash. Notwithstanding the foregoing, if the resulting number of shares of Ambac Stock to be issued to any Existing Shareholder pursuant to this clause 13.2.9 would reasonably be expected to result in that Existing Shareholder beneficially owning (as

determined in accordance with Rule 13d-3 under the Exchange Act) more than 4.9% in aggregate of the Outstanding Shares as of the close of market on the final date of the Trading Period, then the number of shares of Ambac Stock to be issued to each Existing Shareholder shall be decreased pro rata to the extent necessary to ensure that the Existing Shareholders beneficially own in aggregate no more than 4.9% of the Outstanding Shares as of the close of market on the final date of the Trading Period. If, as a result of such reduction in the number of Ambac Stock issued, the Existing Shareholders would receive Ambac Stock with an aggregate value (expressed as a USD cash amount) lower than the amount they would have received without such reduction, then Cirrata shall pay in cash (in GBP) to each Existing Shareholder on the Closing Date an amount equal to such Existing Shareholder’s pro rata amount of such difference. Notwithstanding anything to the contrary in this Deed, if between the final date of the Trading Period and the Closing Date, with respect to the Outstanding Shares, there shall have been any dividend (whether in cash, stock or otherwise) subdivision, reclassification, recapitalisation, split, combination, exchange or readjustment of shares, or any similar event in each case with a record date during such period, then the number of shares of Ambac Stock to be issued will be appropriately adjusted to reflect such dividend, subdivision, reclassification, recapitalisation, split, combination, exchange or readjustment of shares, or any similar event. Subject to the forgoing, the resulting number of shares of Ambac Stock shall be allocated between the Existing Shareholders pro rata, save that the number of shares of Ambac Stock received by any Existing Shareholders may be rounded down by Ambac to the nearest whole number so as not to issue a fraction of a unit of common stock; (c) the Company shall issue to the Existing Shareholder a balancing share certificate for the remaining Shares held by such Existing Shareholder; and (d) notwithstanding the foregoing, the number of shares of Ambac Stock issued pursuant to each Put Option and Call Option, when considered collectively with the number of shares of Ambac Stock issued as Consideration Stock (as defined in the Share Purchase Agreement), shall not exceed 19.9% of the number of outstanding shares of Ambac Stock at the date of the Share Purchase Agreement unless approved by Ambac’s

shareholders pursuant to the rules of the New York Stock Exchange. If such approval is not received prior to the date on which the Ambac Stock would have been issued but for this sub-clause 13.2.9(d), then the number of shares of Ambac Stock to be issued to each Existing Shareholder shall be decreased pro rata to the extent necessary to ensure that when taken together with the shares of Ambac Stock issued as Consideration Stock (as defined in the Share Purchase Agreement) shall not exceed 19.9% of the number of outstanding shares of Ambac Stock at the date of the Share Purchase Agreement. If, as a result of such reduction in the number of Ambac Stock issued, the Existing Shareholders would receive Ambac Stock with an aggregate value (expressed as a USD cash amount) lower than the amount they would have received without such reduction, then Cirrata shall pay in cash (in GBP) to each Existing Shareholder on the Closing Date an amount equal to such Existing Shareholder’s pro rata amount of such difference. 13.2.10 To the extent an Existing Shareholder continues to hold Unexercised Put Options, then such put options shall roll forward such that an additional put option shall become exercisable in respect of Relevant Shares on 1 March 2030 and on 1 March in each subsequent calendar year, and the provisions of this clause 13.2 shall apply as if: (a) such additional put option were a Put Option; and (b) 31 March 2030 and 31 March in each subsequent calendar year were each an Option Exercise Date. 13.2.11 The provisions of clause 13.2.10 shall continue as at 1 March for each subsequent calendar years with references to each year set out in such clause being construed as being the year in such subsequent period until, in respect of an Existing Shareholder, there are no further Unexercised Put Options, at which point such Existing Shareholder's Put Options shall expire, provided that in no event shall any Put Option accumulate such that more than the Relevant Shares can be subject to a Put Option in any calendar year. 13.2.12 The Call Option shall not expire until there are no Unexercised Call Options remaining and the Call Option shall continue to operate in accordance with this clause 13.2 until such expiration. 13.2.13 In the event that Cirrata does not pay (or procure the payment of) any aspect of any amount payable to an Existing Shareholder in respect of the sale and purchase of Relevant Shares by the applicable Closing Date, then:

(a) interest will accrue on such amount unpaid at the US prime rate (as published by the Wall Street Journal) plus 7% per annum from the date such amount should have been paid until the date it is actually paid; and (b) such Existing Shareholder may, at any time prior to such amount and applicable interest being paid, notify Cirrata in writing, such notice to take effect 30 days from the date of such notice, that the sale and purchase pursuant to the applicable Put Option or Call Option shall terminate and the Existing Shareholder shall not be required to sell the applicable Relevant Shares to Cirrata, provided that such termination will not be effective if Cirrata pays such amount and any applicable interest to the Existing Shareholder within the five Business Day period. 13.2.14 Resale Registration Statement (a) If any Put Option or Call Option over an Existing Shareholder's Shares is exercised and Ambac has elected to pay a portion or all of the purchase price in Ambac Stock then, no later than 5:30 pm New York Time on the 5h Business Day (the “Filing Date”) following the Closing Date, Ambac will have filed a registration statement on Form S-3, or if such form is not then available, on Form S-1 (or in each case any successor form) (each, a “Resale Registration Statement”) with the SEC registering the resale of the shares of Ambac Stock delivered to the Existing Shareholder pursuant to this Deed (and any other shares of Ambac Stock issued in respect of the applicable Shares upon any stock split, stock dividend, recapitalization, reclassification, merger, consolidation or similar event) (collectively, such securities until such time that such securities (i) have been disposed of pursuant to an effective Resale Registration Statement, (ii) are able to be sold without restriction as to volume or manner of sale pursuant to Rule 144 or (iii) have been disposed of to a transferee which does not have any rights under this Deed, the “Registrable Securities”) in accordance with any reasonable method of distribution elected by the Existing Shareholders (in such context, each, a “Seller”). Ambac will use reasonable best efforts to cause the Resale Registration Statement to be declared effective by the SEC as soon as practicable thereafter, but in no event later than the earlier of (i) 60 days from the Filing Date and (ii) the 5th Business Day after the date Ambac is notified (orally or in writing, whichever is earlier) by the SEC that the Resale Registration Statement will not be “reviewed” or will not be subject to further review (such date on

which the Resale Registration Statement is declared effective, the “Effective Date”). (b) Ambac will advise each Seller promptly and in any event within one (1) Business Day (at Ambac’s expense): (i) when the Resale Registration Statement or any post-effective amendment thereto has been filed and when it becomes effective; (ii) of any request by the SEC for amendments or supplements to the Resale Registration Statement or the prospectus included therein or for additional information; (iii) of the issuance by the SEC of any stop order suspending the effectiveness of the Resale Registration Statement or the initiation of any proceedings for such purpose; (iv) of the receipt by Ambac of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (v) of the occurrence of any event that requires the making of any changes in the Resale Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading (provided that any such notice will solely provide that the use of the Resale Registration Statement or prospectus has been suspended without setting forth the reason for such suspension). Notwithstanding anything to the contrary set forth herein, Ambac will not, when so advising any Seller of such events, provide such Seller with any material, non-public information regarding Ambac. Ambac will use its best efforts to obtain the withdrawal of any order suspending the effectiveness of the Resale Registration Statement promptly. Upon the occurrence of any event contemplated in clauses (ii) through (v) above, Ambac will use its reasonable best efforts to, as soon as practicable, prepare a post-effective amendment to such Resale Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to the holder of Registrable Securities included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. (c) Once declared effective, Ambac will cause the Resale Registration Statement to be continuously effective and usable until such time as there are no longer any Registrable

Securities (the “Effectiveness Period”). If the Resale Registration Statement ceases to be effective under the Securities Act for any reason at any time during the Effectiveness Period, Ambac will promptly cause the Resale Registration Statement to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Resale Registration Statement) or amend the Resale Registration Statement in a manner reasonably expected to obtain the withdrawal of any order suspending the effectiveness of the Resale Registration Statement. (d) Ambac will supplement and amend the Resale Registration Statement if required by the rules, regulations or instructions applicable to the registration form used by Ambac for such Resale Registration Statement if required by the Securities Act or as reasonably requested by Seller. (e) Ambac will provide a draft of the Resale Registration Statement to each Seller for review at least five (5) Business Days in advance of filing the Resale Registration Statement. In no event will any Seller be identified as a statutory underwriter in the Resale Registration Statement, unless required by the SEC. (f) Upon the effectiveness of any Resale Registration Statement covering any Registrable Securities and in connection with the transfer of any Registrable Securities, Ambac will promptly instruct (or direct its counsel to so instruct and deliver a customary legal opinion) and use reasonable best efforts to cause the Transfer Agent for the shares to (i) remove any restrictive legends related to the book entry account holding such shares and (ii) make a new, unlegended entry for such book entry shares sold or disposed of without restrictive legends. (g) Indemnification. (i) Ambac agrees to indemnify and hold harmless, to the extent permitted by law, any Seller, any Seller’s directors, officers, employees, advisors and agents, to the extent applicable, and any person who controls any Seller (within the meaning of the Securities Act or the Exchange Act) and each affiliate of any Seller (within the meaning of Rule 405 under the Securities Act) (collectively “Covered Persons”) from and against any and all losses, including any liabilities, claims, costs, fees, expenses, taxes, losses, judgments, damages,

fines, awards, settlements and penalties, or injuries, whether or not involving the claim of another person (collectively, “Losses”) caused by any untrue or alleged untrue statement of material fact contained in any Resale Registration Statement, prospectus included in any Resale Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or caused by or related to any violation or alleged violation of the Securities Act or Exchange Act; provided, however, that Ambac will not be liable to any Covered Person in any such case to the extent that any such Loss arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such Resale Registration Statement or prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to Ambac, in writing, by or on behalf of such Covered Person specifically for use in the preparation thereof. (ii) Each Seller agrees to indemnify and hold harmless Ambac against any losses resulting from any untrue statement of material fact contained in the Resale Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by or on behalf of the Seller expressly for use therein. In no event will the aggregate liability of any Seller under this clause (ii) be greater in amount than the dollar amount of the net proceeds received by the Seller upon the sale of the Registrable Securities received by the Seller in connection with the sale of the Registrable Securities pursuant to any Resale Registration Statement. (iii) Any person entitled to indemnification pursuant to this clause (iii) will (A) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice will not impair any person’s right to indemnification hereunder to the extent such failure

has not prejudiced the indemnifying party) and (B) permit such indemnifying party to assume the defence of such claim with counsel reasonably satisfactory to the indemnified party. If such defence is assumed, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent, which consent will not be unreasonably withheld or delayed. An indemnifying party who elects not to assume the defence of a claim will not be obligated to pay the fees and expenses of more than one counsel (and any local counsel as may reasonably be needed) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party will, without the consent of the indemnified party (which consent will not be unreasonably withheld or delayed), consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 13.2.15 For so long as there are any Put Options or Call Options still capable of being exercised (whether at such time or at a future time): (a) the strategic direction of the Group shall be determined by the Board; (b) Cirrata recognises that there is significant value in the Put Options and the Call Options and that neither Cirrata nor any company in the Ambac Group outside the Group shall take any action to intentionally distort the financial performance of the Group in bad faith in a way that adversely affects the calculation of the purchase price of Shares that are the subject of a Put Option or Call Option in accordance with clause 13.2.8 in a way that is not immaterial: (c) Cirrata shall not cause or permit a change to the accounting reference date of any Group Company; or

(d) Cirrata shall procure that the Company does not pay any dividends or other distributions which would have the result that the Group Companies do not have sufficient working capital to carry on their business in accordance with the Business Plan; (e) Cirrata shall not (and shall procure that none of the companies in the Ambac Group outside the Group shall): (i) disclose to companies in the Ambac Group outside the Group any Competitive Information in a way which causes material detriment to the commercial interests of the Group; (ii) use Competitive Information for the benefit of another company in the Ambac Group outside the Group which causes material detriment to the commercial interests of the Group; (iii) systematically target the business, customers, clients or suppliers of any Group Company with the intention of diverting business away from the Group; and; (f) where it or any company in the Ambac Group outside the Group has established, acquired or developed any business that competes with the business of the Group, it shall in good faith work with the Company and the Existing Shareholders with a view to mitigating any negative impact on the business of the Group and reasonably seeking opportunities to achieve synergies and realise opportunities between the businesses. (g) If BCC or any Management Shareholder believes that there is or may be a breach of any of the provisions of this clause 13.2.15(b) through (g), they shall notify the Board as soon as reasonably practicable and in any event within 60 days. Cirrata shall have 30 days to cure such breach. Cirrata shall not be liable for a breach of this clause 13.2.15 to the extent that such liability arose or was increased as a result of a failure by BCC or any Management Shareholder to provide notification to Cirrata within this 60-day period. 13.2.16 BCC payment to Management Shareholders (a) Upon the completion in accordance with clause 13.2.9 of a Transfer of Shares (excluding Additional Shares) held by BCC following the exercise of a Put Option or a Call Option, BCC shall pay an amount equal to 11.97192% of the aggregate exercise price payable to BCC to the Management Shareholders, such amount to be inclusive of the employer costs of Employer National Insurance and apprenticeship levy and be split pro rata to their holdings of the Shares held by the

Management Shareholders as at the date of this Deed. Any such payments shall be made to such bank accounts of such Management Shareholders as they may inform BCC in writing at least two Business Days prior to payment. (b) The Management Shareholders shall be required to pay to their respective employing Group Company all employment-related Tax liabilities owed by any such Management Shareholder under applicable law (including any UK employee income tax and employee and employer National Insurance contributions and their equivalents as applicable under the requirements of the US Internal Revenue Service) in respect of any payment under clause 13.2.16(a), and it is agreed and acknowledged by the parties that such obligation on the part of the Management Shareholders shall be satisfied by: (a) Cirrata deducting an amount equal to such Tax liabilities from the exercise price payable to BCC, and such amount shall be paid to the relevant Group Companies; and (b) BCC shall make the relevant payments under clause 13.2.16(a) to the Management Shareholders net of any Tax so deducted. (c) BCC and the Management Shareholders acknowledge and agree: (a) that the payments referred to in clause 13.2.16(a) recognise the restrictive covenants that apply to the Management Shareholders under clause 11 and the leaver provisions that apply to the Management Shareholders under clause 15; and (b) [***] (d) If as a result of or in consequence of the payments and adjustment pursuant to clause 13.2.16(a), the Company or any other Group Company obtains (by way of deduction, credit or otherwise) the benefit of any deductible expense for corporation tax (a "Tax Benefit"), Cirrata and each Management Shareholder shall procure that the Company or other Group Company (as applicable) shall pay the relevant Management Shareholder(s) (without deduction and pro rata to the payments to be made to them pursuant to clause 13.2.16(a)) an amount equal to the aggregate of: (i) the value of the Tax Benefit obtained by the Company or other Group Company (as applicable); (ii) the value of any further Tax Benefit obtained by the Company or other Group Company (as applicable) as a result of the making of any payment pursuant to clause 13.2.16,

in either case as soon as soon as reasonably practicable upon the Company or other Group Company (as applicable) obtaining such Tax Benefit. 13.3 Sale of Company 13.3.1 If, prior to [●] 2026, there has been: (a) a Change of Control; or (b) an agreement entered into prior to such date pursuant to which, upon completion of such agreement, there would be a Change of Control, then each Existing Shareholder may either: (i) require Cirrata to purchase all of its Shares (other than Shares issued pursuant to the MIP) at the purchase price calculated in accordance with clause 13.2.8 as if all of the Shares held by the Existing Shareholder were Relevant Shares and the date five days prior to the Change of Control were a Option Exercise Date, with completion of such sale and purchase to take place in accordance with clause 13.2.9 as if the giving of such notice were the exercise of a Put Option, with completion of such sale and purchase to take place immediately prior to the Change of Control; or (ii) exercise their tag along rights pursuant to clause 13.5 at the 100% equity value that is the greater of (a) the 100% equity value pursuant to the terms of the Change of Control; and (b) the 100% equity value pursuant to the Share Purchase Agreement less the sum of the total payments made for Shares at Completion and the total payments made in subsequent purchase of Shares from Existing Shareholders pursuant to the exercise of any Call Option or Put Option. For the avoidance of doubt, nothing in this clause 13.3.1 prevents Cirrata from exercising the Drag Along Option in respect of such transaction. In the event that an Existing Shareholder does not elect to use its rights under clause 13.3.1(i) and Cirrata exercises the Drag Along Option, then such Drag Along Option shall be at the 100% equity value that is the greater of (a) the 100% equity value pursuant to the terms of the Change of Control; and (b) the 100% equity value pursuant to the Share Purchase Agreement less the sum of the total payments made for Shares at Completion and the total payments made in subsequent purchase of Shares from

Existing Shareholders pursuant to the exercise of any Call Option or Put Option. 13.3.2 If, after [●] 2026, there has been: (a) a Change of Control other than a Change of Control that was the subject of an agreement falling within clause 13.3.1 (b); or (b) an agreement entered into after such date pursuant to which, upon completion of such agreement, there would be a Change of Control (and such Change of Control takes place in accordance with the terms of such agreement), then any unexercised Put Options and Unexercised Call Options set out in clause 13.2 shall lapse (without prejudice to the provisions of clauses 13.4 and 13.5). 13.3.3 For as long as an Existing Shareholder holds Shares in the Company, Cirrata and Ambac shall consult in good faith with BCC and/or a representative of the Management Shareholders (as applicable) on, and during, the process of any sale of the Company and the operation of a process with the intention of achieving a valuation at fair market value for the Company. 13.3.4 Cirrata shall keep the Existing Shareholders reasonably informed of any discussions or negotiations with any person in respect of a transaction that would, on completion, result in a Change of Control, and of any actual Change of Control. 13.4 Drag Along Rights 13.4.1 Drag Along Sale (a) If there is proposed a sale of Shares by Cirrata to a Proposed Buyer which would result in either a Loss of Control or a Change of Control, Cirrata shall have the right to require all the other Shareholders (but not some only) ("Called Shareholders") to Transfer all their Callable Shares to the Proposed Buyer (or as the Proposed Buyer directs) in accordance with the provisions of this clause 13.4 ("Drag Along Option").

The opinion of the Kings Counsel or barrister shall be made available to both the Company and the Leaver; and (b) the Board must inform the Leaver of its intention to assess whether the Leaver has breached his obligations within 6 months of the Board becoming aware of the circumstances giving rise to the Board's belief that the relevant Leaver has or may have breached his obligations under clause 11 and shall discuss with the Leaver for a further 90 days to attempt to reach agreement between the parties. If agreement is not reached and the Board determines that it wishes to assess whether the Leaver has breached his obligations under clause 11, the Board shall inform the Leaver of the identity of the independent King's Counsel or senior barrister they have nominated to provide the written opinion or formal advice referred to in paragraph (a) above within 12 months of the Board becoming aware of the circumstances giving rise to the Board's belief that the relevant Leaver has or may have breached their obligations under

Guarantee 20.1 Ambac guarantees to the Existing Shareholders and the Company the due and punctual performance, observance and discharge by Cirrata of all the Guaranteed Obligations if and when they become performable or due under this Deed (or (as the case may be) any agreement entered into pursuant to or in connection with it). 20.2 If Cirrata defaults in the payment when due of any amount that is a Guaranteed Obligation, Ambac shall, on five Business Days written notice on demand by an Existing Shareholder, unconditionally pay that amount to the Existing Shareholders in the manner prescribed by this Deed (or (as the case may be) any agreement entered into pursuant to or in connection with it) as if it were Cirrata. 20.3 Ambac as principal obligor and as a separate and independent obligation and liability from its obligations and liabilities under clause 20.1 and clause 20.2, agrees to indemnify and keep indemnified the Existing Shareholders on demand from and against all and any losses, costs, claims, liabilities, damages, demands and expenses suffered or incurred by the Existing Shareholders arising out of, or in connection with, the Guaranteed Obligations not being recoverable for any reason or any failure of Cirrata to perform or discharge any of its obligations or liabilities in respect of the Guaranteed Obligations. 20.4 The guarantee in this clause 20 is and shall at all times be a continuing security and shall cover the ultimate balance of all monies payable by Cirrata to the Existing Shareholders in respect of the Guaranteed Obligations, after

adjustment for any intermediate payment or discharge in full or in part of the Guaranteed Obligations. 20.5 The liability of Ambac under the guarantee in this clause 20 shall not be reduced, discharged or otherwise adversely affected by: 20.5.1 any act, omission, matter or thing which would have discharged or affected the liability of Ambac had it been a principal debtor instead of a guarantor or indemnifier; or 20.5.2 anything done or omitted by any person which, but for this provision, might operate or exonerate or discharge Ambac or otherwise reduce or extinguish its liability under the guarantee in this clause 20. 20.6 Ambac waives any right it may have to require the Existing Shareholders (or any trustee or agent on their behalf) to proceed against or enforce any other right or claim for payment against any person before claiming from Ambac under this clause 20. 20.7 Ambac shall, on a full indemnity basis, pay to the Existing Shareholders on demand the amount of all costs and expenses (including legal and out-of- pocket expenses and any value added tax on them) incurred by the Existing Shareholders in connection with: 20.7.1 the preservation, or exercise and enforcement, of any rights under or in connection with the guarantee in this clause 20 or any attempt so to do; and 20.7.2 any discharge or release of this guarantee. 20.8 Until all amounts which may be or become payable by Cirrata under or in connection with this Deed have been irrevocably paid in full, and unless the Existing Shareholders otherwise direct in writing, Ambac shall not exercise any security or other rights it may have by reason of performing its obligations under this clause 20, whether such rights arise by way of set-off, counterclaim, subrogation, indemnity or otherwise. 20.9 The guarantee in this clause 20 shall be in addition to and independent of all other security which the Existing Shareholders may hold from time to time in respect of the discharge and performance of the Guaranteed Obligations. 20.10 This clause 20 shall automatically terminate on the earlier of: 20.10.1 the Guaranteed Obligations having been satisfied in accordance with the terms of this Deed; or 20.10.2 subject to clause 20.11 and clause 20.12, a Change of Control of the Company; or 20.10.3 subject to clause 20.11 and clause 20.12, Cirrata (or, following any transfer of Shares to another member of the Ambac Group as

23. Damages not an adequate remedy Without prejudice to any other rights or remedies which a party may have under this Deed, the parties acknowledge and agree that damages may not be an adequate remedy for a breach of clauses 10 and 18 and the remedies of specific performance and other equitable relief may be available for any threatened or actual breach of any such provisions and no proof of special damages shall be necessary for the enforcement of the rights under this clause 23. 24. Conflict with the Articles Subject to the provisions of this Deed, if, during the continuance of this Deed, there shall be any conflict between the provisions of this Deed and the provisions of the Articles then, during such period, the provisions of this Deed shall prevail as between the Shareholders. The Shareholders shall exercise all voting and other rights and powers available to them to give effect to the provisions of this Deed and (if necessary and to the extent legally permissible) ensure that any required amendment is made to the Articles.

Waiver No failure or delay by a party to exercise any right or remedy provided under this Deed or by law shall constitute a waiver of that or any other right or remedy, nor shall it prevent or restrict the further exercise of that or any other right or remedy. No single or partial exercise of such right or remedy shall prevent or restrict the further exercise of that or any other right or remedy. 28. Further Assurance Each of the parties shall, and shall use reasonable endeavours to procure that any necessary third party shall, from time to time execute such documents and perform such acts and things as any party may reasonably require to give effect to the terms of this Deed and give any party the full benefit of this Deed. 29.

Assignment 34.1 Subject to clause 34.2 and except as otherwise expressly provided in this Deed, a party may not (whether at law or in equity) without the prior written consent of the other parties (such consent not to be unreasonably withheld or delayed) assign, transfer, grant any security interest, hold on trust or deal in any other manner with the benefit of the whole or any part of this Deed, nor purport to do any of the same. 34.2 Each Shareholder may assign the whole or any part of its accrued rights under this Deed to any person to whom Shares are Transferred in accordance with this Deed and the Articles and who has executed and delivered a Deed of Adherence (or is otherwise a party to this Deed as a Shareholder).

Process Agent 38.1 Subject to clause 38.4, any party that is not incorporated or resident within the United Kingdom (each a "Relevant Party") shall appoint and thereafter maintain (for so long as any claim may be brought under or in connection with this Deed) the appointment of an agent within England for service of proceedings in relation to any matter arising under or in connection with this Deed (the "Process Agent") as soon as practicable and, in any event, within 28 days of the date of this Deed and service on the Process Agent in accordance with clause 23.2 shall be deemed to be effective service on the Relevant Party. Upon the service of proceedings on a Process Agent appointed by or on behalf of the Relevant Party in relation to any matter arising under or in connection with this Deed, a copy of such proceedings shall also be delivered

to that Relevant Party in accordance with clause 22, it being acknowledged and agreed that delivery of or failure to deliver a copy of the proceedings to such Relevant Party shall not prejudice the service of proceedings on its Process Agent. 38.2 A Relevant Party shall notify the other parties in writing of any change in the address of the Process Agent within 28 days of such change. 38.3 Failure by any Process Agent appointed under this clause 38 to notify the Relevant Party of the service of process will not invalidate the proceedings concerned. 38.4 A Relevant Party shall not be required to appoint a Process Agent for so long as any party to this Deed is able to serve proceedings on the Relevant Party without having to take any further action or obtain any further consent than would be required if the Relevant Party had appointed a Process Agent in England. 38.5 If the Process Agent described in clause 38.1 ceases to be able to act as such or to have an address in England, the Relevant Party shall appoint a new Process Agent in England and shall deliver to the parties within 14 calendar days a copy of a written acceptance of appointment by the Process Agent. 38.6 Nothing in this Deed shall affect the right of service of process in any other manner permitted by law.
