高手帮我翻译一下下面这段英文？

US$ 500,000 of debentures will be issued with maturity dates ranging from three to five years and will be secured by a second floating charge on the undertaking (i.e. ranking under the fixed charge from the main international agency lender). As envisaged in this proposal the debentures will carry a coupon of 13% a year paid quarterly in arrears. Alternatively, as the source of funds for these borrowing will be private monies from within and outside Zimbabwe, they may be issued interest free but with a higher redemption value on maturity to avoid withholding tax on interest.
