FUNDING AGREEMENT No. 7-9749

     This Agreement is issued in connection with the issuance by the Trust (specified in the Annex) of secured medium-term notes (the “Notes”) which comprise a Series of Notes which are identified in the annex hereto (the “Annex”) and which are being issued by the Trust pursuant to the Prospectus dated November 21, 2007, the Prospectus Supplement dated November 21, 2007, as from time to time amended or supplemented, and the Pricing Supplement applicable to such Notes (the “Pricing Supplement”). Capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Notes. Where used in this Agreement, the term “Notes” and “Series of Notes” shall mean the Notes and the Series of Notes secured by this Agreement as the same exist on the Effective Date, without giving effect to any amendments or modifications to said Notes or Series of Notes effected or made after any such Effective Date unless such amendments or modifications to said Notes or Series of Notes have been consented to in writing by Principal Life.

1.		Deposit
		Principal Life agrees to accept, and the Agreement Holder agrees to pay or cause to be paid to Principal Life, for value on the Effective Date, the Net Deposit (as specified in the Annex). All funds received by Principal Life under this Agreement shall become the exclusive property of Principal Life and remain a part of Principal Life’s general account without any duty or requirement of segregation or separate investment.
		This Agreement shall become effective only upon the receipt by Principal Life or its designee of the Net Deposit.
2.		Fund
		Upon receipt of the Net Deposit, Principal Life will establish, under this Agreement, a bookkeeping account in the name of the Agreement Holder, which will evidence Principal Life’s obligations under this Agreement.
		The Deposit deemed received (as specified in the Annex), (i) less any withdrawals to make payments hereunder (other than Additional Amounts (as defined in the Annex), if applicable) and (ii) plus any interest accrued and premium, if any, pursuant to Section 7, will be referred to as the “Fund”.
		Principal Life is neither a trustee nor a fiduciary with respect to the Fund.
3.		Purchase of Notes By Principal Life
		Principal Life may purchase some or all of the Notes in the open market or otherwise at any time, and from time to time. Simultaneously, upon such purchase, (1) the purchased Notes shall, by their terms become mandatorily redeemable by the Trust as specified in the related Pricing Supplement, Prospectus Supplement and/or Prospectus and (2) the Fund under this Agreement shall be permanently reduced by the same percentage as the principal amount of the Notes so redeemed bears to the sum of (i) the aggregate principal amount of all Notes issued and outstanding immediately prior to such redemption and

		the principal amount of the Trust Beneficial Interest related to such series of Notes. If Principal Life, in its sole discretion, engages in such open market or other purchases, then the Trust, the Indenture Trustee in respect of such Notes, and Principal Life shall take such actions (including, in the case of Principal Life, making the payment(s) necessary to effect the Trust’s redemption of such Notes) as may be necessary or desirable to effect the cancellation of such Notes by the Trust.
4.		Entire Agreement
		This Agreement and the Annex attached hereto constitute the entire Agreement.

	(ii)		this Agreement has been duly authorized, executed and delivered, this Agreement constitutes a legal, valid and binding obligation of each party hereto, and this Agreement is enforceable in accordance with the terms hereof, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights, and subject as to enforceability to general principles of equity, regardless of whether enforcement is sought in a proceeding in equity or at law; and

(b) The Trust further represents and warrants to Principal Life that:

6.		Assignment of Agreement
		The following conditions must be satisfied in order to effectuate any assignment of this Agreement:

	(i)		This Agreement may only be transferred through a book entry system maintained by Principal Life, or an agent designated by it, within the meaning of Temporary Treasury Regulations Section 5f.103-1(c) and Treasury Regulations Section 1.871-14(c)(1)(i).

Once the foregoing conditions have been satisfied with respect to an assignment, the assignee or its successor shall be deemed to be the sole Agreement Holder for all purposes of this Agreement and Principal Life shall promptly amend its records to reflect the assignee’s status as Agreement Holder.
7.		Payments to the Agreement Holder
		Principal Life shall pay to, or at the direction of, the Agreement Holder by the date (the “Due Date”) on which any payment becomes due in respect of the Notes secured by this Agreement (and in any event such period of time prior to the Due Date as shall be necessary to ensure that the Trust can fulfill its obligation to make payment in full of all amounts due and payable under such Notes on the Due Date), an amount in the currency or currencies in which the Notes are denominated as specified in the Notes equal to the sum of (i) the amount of principal and/or (as the case may be) interest and/or (as the case may be) premium falling due in respect of such Notes on such Due Date (the “Notes

4

		Component”) and (ii) the amount of any payments owed by the Trust in respect of the Trust Beneficial Interest (issued in connection with the Series of Notes secured by this Agreement) falling due on such date (the “Beneficial Component”). In the event that Principal Life fails to make payment of any such amount on or prior to the Due Date, Principal Life shall pay to or at the direction of the Agreement Holder, on demand by the Agreement Holder, (i) if the failure relates to the Notes Component, an amount in the currency specified in the Notes equal to the amount of default interest (or other amount) which becomes due and payable by the Trust in accordance with the Notes as a consequence of any delay in the Trust making the relevant payment of principal, interest or premium (as the case may be) to the holders of such Notes and (ii) if the failure relates to the Beneficial Component, such amount of default interest, if any, determined in the same manner as default interest on the Notes Component.
		Interest shall accrue on the Fund in the same amount and pursuant to the same terms as interest accrues on the Notes secured by this Agreement and on the Trust Beneficial Interest related to the Notes.
		If any amount is withdrawn from the Fund in order to make a payment under this Section 7, interest will cease to be credited with regard to such amount as of the end of the day immediately preceding the date on which such withdrawal is made.
		All payments made by Principal Life to the Agreement Holder hereunder shall be paid in same-day, freely transferable funds to such account as has been specified for such purpose by the Agreement Holder.
		Notwithstanding anything to the contrary in this Section 7, if Principal Life shall, with respect to any scheduled amount due and payable under any of the Notes, comply in all respects with the requirements of this Section 7, but an event of default has occurred with respect to the Notes and as a result payments with respect to the Notes have been accelerated, otherwise than by reason of any default under this Agreement by Principal Life, no Event of Default (as defined below) under this Funding Agreement shall be deemed to have occurred, no payments with respect to this Agreement shall be accelerated and Principal Life will remain obligated to make payments under this Agreement as if no event of default had occurred with respect to the Notes.
8.		Termination of Agreement
		Subject to the provisions of the following paragraph and the Annex, this Agreement shall terminate and cease to be of any further force or effect on the day and at the time upon which all amounts have been withdrawn from the Fund pursuant to this Agreement.
		Upon the occurrence of any of the following events (each, an “Event of Default”) and following a written demand by the Agreement Holder, Principal Life shall pay to, or at the direction of, the Agreement Holder all amounts that the Trust is required to pay in such event under the Notes and the Trust Beneficial Interest:

(i) Principal Life’s failure to make any payment of interest, premium (if applicable), installment payments (if applicable) or Additional Amounts (if and as specified in

5

			the Annex) in accordance with this Agreement, if such failure to pay is not corrected within seven (7) Business Days after such payment becomes due and payable; or
	(ii)		Principal Life’s failure to make any payment of principal (other than any installment payment) in accordance with this Agreement, if such failure to pay is not corrected within one (1) Business Day after such payment becomes due and payable; or
	(iii)		if Principal Life (a) is dissolved (other than pursuant to a consolidation, amalgamation or merger in which the resulting entity assumes its obligations); (b) becomes insolvent or is unable to pay its debts or fails or admits in writing its inability generally to pay its debts as they become due; (c) makes a general assignment, arrangement or composition with or for the benefit of its creditors; (d) institutes or has instituted against it an administrative or legal proceeding seeking a judgment of insolvency or bankruptcy or any other relief under any supervision, rehabilitation, liquidation, bankruptcy or insolvency law or other similar law affecting creditors’ rights, or a petition is presented for its winding-up or liquidation, and, in the case of any such proceeding or petition instituted or presented against it, such proceeding or petition (1) results in a judgment of insolvency or bankruptcy or the entry of an order for relief or the making of an order for its rehabilitation, winding-up or liquidation or (2) is not dismissed, discharged, stayed or restrained in each case within 60 days of the institution or presentation thereof; (e) has a resolution passed for its rehabilitation, winding-up, official management or liquidation (other than pursuant to a consolidation, amalgamation or merger in which the resulting entity assumes the obligations of Principal Life); (f) seeks or becomes subject to the appointment of an administrator, supervisor, rehabilitator, provisional liquidator, conservator, receiver, trustee, custodian or other similar official for it or for all or substantially all its assets; (g) has a secured party take possession of all or substantially all its assets or has a distress, execution, attachment, sequestration or other legal process levied, enforced or sued on or against all or substantially all its assets and such secured party maintains possession, or any such process is not dismissed, discharged, stayed or restrained, in each case within 60 days thereafter; (h) causes or is subject to any event with respect to it which, under the applicable laws of any jurisdiction, has an analogous effect to any of the events specified in clauses (a) to (g) (inclusive); or (i) takes any action in furtherance of, or indicating its consent to, approval of, or acquiescence in, any of the foregoing acts.

Notwithstanding anything to the contrary in this Section 8, if an event described in clause (iii) above occurs, this Agreement will automatically terminate and the amount of the Fund will be immediately due and payable by Principal Life to the Agreement Holder, or the account specified by the Agreement Holder.

Principal Life will promptly notify the Agreement Holder and the Rating Agencies in writing of the occurrence of any of (i) through (iii) above.

9.		Withholding; Additional Amounts
		All amounts due in respect of this Agreement will be made without 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 by or on behalf of any governmental authority in the United States unless the withholding or deduction is required by law. Unless otherwise specified in the Annex, Principal Life will not pay any additional amounts to the Agreement Holder in the event that any withholding or deduction is so required by law, regulation or official interpretation thereof, and the imposition of a requirement to make any such withholding or deduction will not give rise to an Event of Default or any independent right or obligation to redeem this Agreement.
10.		Currency
		Except as may be specifically noted in the Annex, the Net Deposit and all payments under Section 7 of this Agreement shall be made using the currency or currencies as specified in the Notes.
11.		Tax Treatment
		Principal Life and the Agreement Holder agree that this Agreement shall be disregarded for U.S. Federal income tax purposes. Principal Life and the Agreement Holder further agree that if this Agreement is not so disregarded, it will and is intended to be treated as a debt obligation of Principal Life issued in registered form within the meaning of Treasury Regulations Section 1.871-14(c)(1)(i), except to the extent provided in Treasury Regulations Section 1.163-5T (or any subsequent similar regulation).
12.		Amendment and Modification
		This Agreement may be amended or modified in whole or in part, at any time and from time to time, for any period or periods (a) by mutual written agreement by such officers of Principal Life, the Agreement Holder and, where such Agreement Holder is the Indenture Trustee upon an assignment by way of security of this Agreement by the Trust, the Trust and (b) without the consent of any other person affected thereby.
