[1] The Company has collateralized all borrowings under the 5.95% fixed rate bonds by providing a first debenture over fixed and floating assets, a first legal charge over all land and buildings, a security interest in all insurance policies and claims, a reimbursement agreement for standby letters of credit, a pledge of capital stock of each subsidiary and guarantees and negative pledges from each subsidiary. The trust deed for these bonds restricts the Company's ability to enter into new borrowing agreements or any new guarantees without prior approval of the trustee and limits our capital expenditures, with the exception of capital expenditures to be incurred on certain defined projects, to $2.0 million annually without prior approval by the trustee. The trust deed also contains financial covenants that require the Company to maintain a debt service coverage ratio, a ratio of long term debt to EBITDA (i.e. earnings before interest, taxes, depreciation and amortization) for the 12 months preceding the ratio calculation date and a ratio of long term debt to equity. As of December 31, 2012, the Company was in compliance with the covenants under the trust deed.

[2] In July 2005, CW-Bahamas sold B$10.0 million Series A bonds to Bahamian citizens and permanent resident investors in The Bahamas to finance a portion of the construction cost of its Blue Hills plant. These bonds had a maturity date of June 30, 2015 and accrued interest at the annual fixed rate of 7.5%. CW-Bahamas had the option to redeem the bonds in whole or in part without penalty commencing after June 30, 2008. The Company guaranteed CW-Bahamas' repayment obligations upon an "event of default" as defined in the guarantee agreement. The Company redeemed $1.5 million of these bonds in September 2010 and redeemed the remaining balance of these bonds on March 31, 2012.

[3] In October 2011, the Company entered into a $10.0 million Credit Agreement which included a non-revolving credit facility. The credit facility had an expiration date of one year from the date of the initial advance. The initial advance of $7.5 million was drawn on December 30, 2011. Interest on this loan was based on the bank's term deposit rate plus 1% per annum. The Company was required to maintain an interest bearing cash deposit account as collateral for the borrowings in an amount equal to the amount of the borrowings. The Company repaid this loan in April 2012.
