 The Borrower wishes to provide additionally adjusting in some
conditions and confirmations of the Loan agreements. The Borrower and Bank therefore execute this Memorandum as follows: 
 1. This is to cancel
all of the contents in Clause 5 in regard to Memorandum of the Loan agreement dated 4 March 2004 and then proceed with this content instead. 
 “5. Fabrinet shall maintain the overall financial ratios at the end of December and June of each year throughout the period of extending credit by the Bank as follows: 
 5.1 Fabrinet shall maintain the debt service coverage ratio (DSCR) at not lower than 2.50. The DSCR is calculated as follows: 
 Earnings before interest and depreciation and amortization + Cash on Hand – Short-term Debt 
  
 Current portion of Long-term Debt +
Interest Expenses 
 5.2 Fabrinet shall maintain its Debt to Equity Ratio (D/E Ratio) at no more than 2.00. The D/E ratio is
calculated as follows: 
 Total Liabilities including contingent liabilities 
  
 Shareholder’s and equity -
Intangible asset - Related party receivable - Investment 
 2. This is to cancel all of the contents in Clause 13 in regard to Memorandum of the
Loan agreement dated 4 March 2004 and then proceed with this content instead. 
 “13. Fabrinet shall maintain its Debt
Service Coverage Ratio (DSCR) after payment of dividend at not lower than 2.50, using the calculation basis under Clause 5.1”

 4. If the Borrower is in default or fails to comply with the Loan agreement and/or this memorandum, the
Borrower shall be deemed to be in default of this memorandum and Loan agreement. The Bank can charge interest at the default rate per the Loan agreement. Additionally, the Bank still maintains its right to enforce the Borrower the Loan agreement.

 5. The Borrower and the Bank apparently agree that concluding this memorandum does not mean to be converting the loan and is to be treated
this memorandum as part of the Loan agreement. Words or contents in this memorandum have to be the same meaning as meaning in Loan agreement except for that this memorandum defines in other meanings. 
 If terms and conditions are not mentioned clearly in this memorandum, the loan agreement will be applied. 
 In Witness Whereof, the Borrower has thoroughly read and understood the contents above, and has therefore signed (with seal affixed) in the presence of
