We will amortize the $&lt;font class="_mt"&gt;14.2&lt;/font&gt;&amp;nbsp;million we incurred in underwriting discounts and offering expenses into interest expense over the ten-year term of the notes. The notes are senior unsecured obligations of NII Capital Corp., a domestic subsidiary that we wholly own, and are guaranteed by us and by certain of our other domestic wholly-owned subsidiaries. These guarantees are full and unconditional, as well as joint and several. Subject to certain exceptions, the notes are equal in right of payment with any future unsecured, unsubordinated indebtedness of NII Capital Corp. and of the guarantors of the notes, including, but not limited to, with respect to NII Holdings' guarantee, NII Capital Corp.'s &lt;font class="_mt"&gt;10.0&lt;/font&gt;% senior notes due &lt;font class="_mt"&gt;2016&lt;/font&gt;, NII Capital Corp.'s &lt;font class="_mt"&gt;8.875&lt;/font&gt;% senior notes due&amp;nbsp;&lt;font class="_mt"&gt;2019&lt;/font&gt; and NII Holdings' &lt;font class="_mt"&gt;3.125&lt;/font&gt;% convertible notes due &lt;font class="_mt"&gt;2012&lt;/font&gt;. The notes are effectively subordinated to all NII Capital Corp.'s existing and future secured indebtedness, as well as to all existing and future indebtedness of our subsidiaries that are not guarantors of the notes, including the foreign subsidiaries that operate in each of our markets. The notes bear interest at a rate of &lt;font class="_mt"&gt;7.625&lt;/font&gt;% per year, which is payable semi-annually in arrears on April 1 and October&amp;nbsp;1, beginning on October&amp;nbsp;1, 2011 and will mature on &lt;font class="_mt"&gt;April&amp;nbsp;1, 2021&lt;/font&gt;. &lt;/div&gt;

&lt;div style="margin-top: 6pt; font-size: 10pt;" align="left"&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;The notes are not entitled to any mandatory redemption or sinking fund. Prior to April&amp;nbsp;1, 2014, up to &lt;font class="_mt"&gt;35&lt;/font&gt;% of the aggregate principal amount of the notes may be redeemed with the net cash proceeds from specified equity offerings at a redemption price of &lt;font class="_mt"&gt;107.625&lt;/font&gt;% of their principal amount, plus accrued and unpaid interest. Such redemption may only be made if, after the redemption, at least &lt;font class="_mt"&gt;65&lt;/font&gt;% of the aggregate principal amount of the notes issued remains outstanding. In addition, prior to April&amp;nbsp;1, 2016, NII Capital Corp. may redeem the notes, in whole or in part, at a redemption price equal to &lt;font class="_mt"&gt;100&lt;/font&gt;% of the principal amount thereof plus a "make-whole" premium and accrued and unpaid interest. At any time on or after April&amp;nbsp;1, 2016 and prior to maturity, the notes will be redeemable, in whole or in part, at the redemption prices presented below (expressed as percentages of principal amount), plus accrued and unpaid interest to the redemption date if redeemed during the 12-month period beginning on April 1 of the applicable year: &lt;/div&gt;
