Additional Amounts to be Paid for Withholding Tax.
 
The Trust shall pay to a holder of a Note who is not a “United States person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code of 1986 (the “Code”) additional amounts to compensate for any withholding or deduction for or on account of any present or future taxes, duties, levies, assessments or other governmental charges of whatever nature imposed or levied on payments in respect of such Note, by or on behalf of any governmental authority in the United States having the power to tax, so that the net amount received by the holder under that Note, after giving effect to such withholding or deduction, will equal the amount that would have been received under such Note were no such deduction or withholding required; provided that the Trust shall not be required to make any payment of any additional amount for or on account of: (i) any tax, duty, levy, assessment or other governmental charge imposed which would have not been imposed but for (A) the existence of any present or former connection between the holder or beneficial owner (as determined for United States federal income tax purposes) of the Note or the Funding Agreement (any such holder or beneficial owner, the “Owner”) and such governmental authority, including without limitation, being or having been a citizen or resident thereof, or being or having been present therein, incorporated therein, engaged in a trade or business therein or having (or having had) a permanent establishment or principal office therein, (B) such Owner being or having been a controlled foreign corporation within the meaning of Section 957(a) of the Code, related within the meaning of Section 864(d)(4) of the Code to Principal Life or a private foundation or other tax-exempt organization, (C) such Owner being or having been an actual or constructive owner of ten percent (10%) or more of the total combined voting power of all the outstanding stock of Principal Life, (D) such Owner being a bank for United States federal income tax purposes whose receipt of interest on the Note or Funding Agreement is described in Section 881(c)(3)(A) of the Code or (E) such Owner being subject to backup withholding as of the date of becoming an Owner; (ii) any tax, duty, levy, assessment or other governmental charge which would not have been imposed but for the presentation of the Note or other evidence of beneficial ownership thereof (where presentation is required) for payment on a date more than thirty (30) days after the date on which such payment becomes due and payable or the date on which payment is duly provided for whichever occurs later; except to the extent that the Owner would have been entitled to additional amounts had the Note been presented on the last day of such thirty (30) day period; (iii) any tax, duty, levy, assessment or other governmental charge which is imposed or withheld by reason of the failure of an Owner to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the United States of an Owner (including, without limitation, failure to provide IRS Forms W-8BEN or W-8ECI), if compliance is required by statute, by regulation of the United States Treasury Department, judicial or administrative interpretation, other law or by an applicable income tax treaty to which the United States is a party as a condition to exemption from such tax, duty, levy, assessment or other governmental charge; (iv) any inheritance, gift, estate, personal property, sales, transfer or similar tax, duty, levy, assessment or similar governmental charge; (v) any tax, duty, levy, assessment or other governmental charge that is payable otherwise than by withholding from payments in respect of the Note; (vi) any tax, duty, levy, assessment or other governmental charge that would not have been imposed or withheld but for the treatment of payments in respect of the Note or the Funding Agreement as contingent interest described in Section 871(h)(4) of the Code; (vii) any tax, duty, levy, assessment or other governmental charge that would not have been imposed or withheld but for an election by the Owner the effect of which is to make payment in respect of the Note subject to United States federal income tax; (viii) any tax, duty, levy, assessment or other governmental charge resulting from a European Union Directive; or (ix) any combination of items (i), (ii), (iii), (iv), (v), (vi), (vii) or (viii).
 
Principal Life shall pay to the Trust additional amounts to reimburse the Trust for additional amounts paid by the Trust to the holder of a Note in accordance with the terms specified in this Pricing Supplement and the Note. If Principal Life is required, or based on an opinion of independent legal counsel selected by Principal Life a material probability exists that Principal Life will be required, to pay additional amounts in respect of such withholding or deduction, pursuant to (a) any amendment to, or change (including any announced prospective change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein or (b) any amendment to, or change in, an interpretation or application of any such laws or regulations by any governmental authority in the United States, which amendment or change is enacted, promulgated, issued or announced on or after the effective date of the Funding Agreement, Principal Life will have the right to redeem the Funding Agreement by giving not less than 30 and no more than 60 days prior written notice to the Trust and by paying the Trust the outstanding principal of, and accrued but unpaid interest on, the Funding Agreement. If Principal Life redeems the Funding Agreement issued to the Trust, the Trust will redeem all of the Notes at the outstanding principal balance of, and accrued but unpaid interest on, the Notes, plus additional amounts, if any.
 
                   
Special Tax Considerations:
Interest payable on the Notes will be treated as “qualified stated interest” for United States federal income tax purposes, as it meets the specified criteria referenced in the prospectus supplement under the heading “Material United States Federal Income Tax Considerations-U.S. Holders-Interest and Original Issue Discount”.
