“(e) (i) the liabilities of Sirius Belgium (other than liabilities incurred by Sirius Belgium after the Closing Date as a result of actions taken after the Closing Date

ABB and Purchaser agree that ABB shall (i) prepare and file all amended Tax Returns with respect to the Belgian Tax Reassessments and shall control any Tax Claim arising therefrom and (ii) be solely responsible for taking any and all actions necessary or appropriate to recover any amounts payable to any Acquired Company as a result of a Belgian Tax Reassessment Claim. Purchaser shall cooperate, so long as such cooperation in Purchaser’s good faith and reasonable judgment can be made without undue burden or expense or disruption to the operations of the Business, with ABB’s reasonable requests for information held by an Acquired Company, or assistance from an Acquired Company, in order to enable ABB to take any of the actions described in the immediately preceding sentence. Purchaser shall be under no obligation to utilize any refunds, credits or offsets of Taxes attributable to or resulting from the liquidation of Sirius Belgium. If Purchaser, in its sole discretion, determines that, after first taking into account all other items of income, gain, loss, deduction, credit or reserve (including safety reserve) that are available for the relevant taxable period or periods, Sirius International or any affiliate or successor thereto actually utilized any credits or offsets resulting from the liquidation of Sirius Belgium and either (i) such utilization actually reduces the amount of Taxes that Sirius International or any affiliate or successor thereto otherwise would have been required to pay to a taxing authority had it not utilized such credits or offsets or (ii) Sirius International or any affiliate or successor thereto receives a refund or credit against its Taxes from a taxing authority that it would not otherwise have received had it not utilized such credits or offsets, then the amount of such reduction of Taxes paid or the amount of such refund or credit shall be 80 percent

for the account of ABB and 20 percent for the account of Purchaser, provided, however, that ABB agrees to repay to Purchaser its 80 percent portion of the amount of such reduction or the amount of such refund or credit (plus any penalties, interest or other charges imposed by a taxing authority) in the event that (x) it is determined by a taxing authority that Sirius International was not entitled to such reduction of Taxes paid or (y) Sirius International or any affiliate or successor thereto is required to repay such refund to a taxing authority. ABB and Purchaser agree that (i) ABB will provide reasonable instructions in the preparation and filing of all Tax Returns that relate to the liquidation of Sirius Belgium and (ii) all expenses relating to (a) the liquidation of Sirius Belgium, (b) the preparation of such Tax Returns and (c) the recovery of any amounts payable to any Acquired Company as a result of a Belgian Tax Reassessment Claim shall be borne solely by ABB. For the avoidance of doubt. the amount or economic benefit of any refunds, credits or offsets of Taxes attributable to or resulting from the Belgian Tax Reassessments, the liquidation of Sirius Belgium and each Belgian Tax Reassessments Claim shall not in any way increase Net Equity.

(c) Each party shall forward, and shall cause its Affiliates to forward, to the party entitled pursuant to this Section 9.6.4 to receive the amount or economic benefit of (i) a refund, credit or offset to Tax the amount of such refund, or the economic benefit of such credit or offset to Tax, within 10 days after such refund is received or after such credit or offset is allowed or applied against another Tax liability, as the case may be, and (ii) a Belgian Tax Reassessments Claim the amount of such Belgian Tax Reassessments Claim, within 10 days after such amount is received.”

6. Prior to the Closing, ABB shall deliver to Purchaser the report attached as Exhibit A hereto executed by the Business Auditors.

ABB and Purchaser hereby agree and acknowledge that (i) Purchaser has not granted any written consents under Section 7.2.4 or 7.2.6 of the Agreement, (ii) Purchaser has not waived any of its rights under the Agreement, including, without limitation, any of its rights under Article 9 of the Agreement, with respect to breaches, if any, by ABB of any of its representations, warranties, covenants and agreements contained in the Agreement, whether asserted or unasserted or known or unknown by Purchaser as of the date of this Amendment and in each case relating to or arising out of the preparation, content or delivery of the Audited Closing Financial Statements and the Audited Closing Net Equity Statement and (iii) Purchaser shall not be deemed to have granted any such consent or made any such waiver described in clauses (i) and (ii) by virtue of any act or failure to act by Purchaser, including, without limitation, proceeding with the Closing, other than, and only to the extent, as specifically set forth in a written instrument delivered by Purchaser to ABB after the date of this Amendment; provided, however, that this Section 7 of this Amendment shall not constitute an amendment to the Agreement nor shall it in any way affect the rights of Purchaser or any of its Affiliates (including any Acquired Company) arising out of or relating to the Agreement.

IN WITNESS WHEREOF, the parties hereto have executed this Amendment effective as of the day and year first written above.
