WHEREAS, the parties entered into a Participation Agreement dated January 5, 2007, as amended (the "Agreement");

WHEREAS, the parties desire to add PRINCIPAL MANAGEMENT CORPORATION ("PMC") as a party to this Agreement;

NOW THEREFORE, PVC, PFDI, PMC and the Company hereby agree to amend the

Agreement as follows:

1.     Schedule A to the Agreement is hereby restated, in its entirety, and replaced with

Schedule A attached hereto.

2.     Schedule B to the Agreement is hereby restated, in its entirety, and replaced with Schedule B attached hereto. The payment to be made in February 2010 will be the first payment under this new schedule.

3.     Section 2.3 is replaced and superseded by the following:

The Company shall bear the costs of printing PVC's prospectus, profile (if any), statement of additional information, shareholder reports and other shareholder communications (including sales literature) which are to be distributed to, and the costs of distributing such materials to, owners of and applicants for Contracts for which PVC is serving or is to serve as an underlying investment vehicle. The Company shall bear the costs of distributing proxy materials (or similar materials such as voting solicitation instructions) to Contract owners.

PMC agrees to pay the Company an administrative fee based on the terms of this Agreement, including the attached Schedule B, for reimbursement for the costs associated with the printing and distribution of materials and with the administrative processing of PVC Fund shares.

In the event of a change in law or regulation pertaining to payments under Rule 12b- l plans, or termination or amendment of the 12b-1 plan by the fund Board, any obligation of PFDI to pay 12b- 1 fees may either be terminated or be modified, as appropriate, by revising the Rule 12b-1 Plans to comply with such change.

5. The following is added to the Agreement as a new Section 6.5:

Notwithstanding the termination of this Agreement, for Contracts in effect as of the date of termination PMC shall continue to pay the administrative fees payable pursuant to the terms of this Agreement while such Contracts remain in effect, provided the Company continues to perform its obligations under this Agreement. The administrative fees disclosed on Schedule B may be revised upon agreement of PMC and PLIC.

6. Terms used, but not defined herein, shall have the same meaning assigned to them in the Agreement. Except as expressly amended by this Addendum, the terms and conditions of the Agreement remain in full force and effect.

The monthly administrative fee payable on the Money Market Account is subject to change each quarter. The actual administrative fee payable month l y on the Money Market Account during a quarter will be calculated based on the gross yield on the PVC Money Market Account as of the last day of the preceding quarter. The 0.095% administrative fee in the table above is an estimate based on an assumption that the gross yield on the PVC Money Market Account will be 30 basis points as of December 31, 2009. The actual administrative fee will range from an annual rate of a maximum of 0.145% to a minimum of 0.0%. The administrative fee for any quarter will be determined based on the gross yield on the PVC Money Market Account as of the last day of the preceding quarter, and for each 2 basis point increase in the gross yield above 30 basis points, the administrative fee will increase by 1 basis point, to a maximum annual rate of 0. 145%. For each 2 basis point reduction in the gross yield below 30 basis points, the administrative fee will decrease by l basis point to a minimum of 0.0% if the gross yield falls to 11 basis points or below.
