Such interest shall be calculated daily on the basis of a 365 day year and the actual number of days elapsed.”

“Singapore Prefund Amount” means $9,340,618.”

“Specified Transfer Funds” means $4,911,312 (which is net of a 10% Malaysian withholding tax suffered at the Group Companies from $5,457,132) that Swire Pacific Offshore (Pte.) Ltd conveyed and transferred immediately prior to Closing from its United States Dollar bank account to Seller Parent to repay an outstanding intercompany loan in such amount.”

“Retained Identified Liabilities” means any Retained Liabilities described in clauses (a), (c), (d), (e), (i) and (j) of the definition of Retained Liabilities; provided that, unless Buyer has repaid the Malaysian Prefund Amount and Prefund Interest to Seller in accordance with Section 2.4(h), any payment by a Group Company pursuant to an IRB Notice of Assessment shall only be a Retained Identified Liability to the extent such payment exceeds the Malaysian Prefund Amount and the amount of the Prefund Interest accrued through the date of such payment (in each case less amounts credited to the Final Cash Consideration pursuant to Section 2.4(a)(v)) .”

SECTION 3. Amendments to Section 2.2 of the Purchase Agreement. Section 2.2 of the Purchase Agreement shall be amended to add the following sentence at the end of such section:

“The Parties agree that the Singapore Prefund Amount shall be included in Estimated Closing Indebtedness; provided, Buyer and, after the Closing, the Group Companies shall apply such amount to pay for and satisfy Tax and other Liabilities resulting from or in connection with the matters set forth in paragraphs 5, 14 and 15 of Section 5.12(b) of the Seller Disclosure Schedules and the related notice of assessment of the Inland Revenue Authority of Singapore to the extent such Tax and other Liabilities are reflected in the Year of Assessment 2022 Notice of Assessment (Original Estimated) dated April 7, 2022, issued by the Inland Revenue Authority of Singapore to the Group Companies.”
