FOURTH AMENDMENT TO SELLING AND SERVICES AGREEMENT

Exhibit 24(b)(8.15)

FOURTH AMENDMENT

This Fourth Amendment dated as of April 6, 2009 by and between ING Life Insurance and Annuity Company (formerly Aetna Life Insurance and Annuity Company) (“ING Life”), ING Institutional Plan Services, LLP (“ING Institutional”), ING Financial Advisers, LLC (formerly Aetna Investment Services, Inc.)(“ING Financial”)(collectively “ING”), American Century Investment Services, Inc. (“Distributor”), and American Century Services, LLC (formerly known as American Century Services Corporation)(“Fund Agent”) is made to the Selling and Services Agreement dated as of July 1, 2000 (the “Agreement”) as amended on April 1, 2007, October 1, 2004, and November 7, 2003. Terms defined in the Agreement are used herein as therein defined.

WHEREAS, ING Institutional is a limited liability company that provides various recordkeeping and other administrative services to certain Plans; and

WHEREAS, the parties wish to add ING Institutional to the Agreement; and

WHEREAS, the parties wish to amend certain other provisions of the Agreement, as provided below.

NOW, THEREFORE, in consideration of the promises and mutual covenants hereinafter contained, the parties agree as follows:

1. ING Institutional is hereby added to the Agreement as an additional recordkeeper, and all provisions relating to ING Life in the Agreement are hereby amended to refer to both ING Life and ING Institutional. The defined term “ING” in the Agreement is hereby amended to include ING Life, ING Institutional, and ING Financial.

2. Paragraph 3 of the Agreement is hereby deleted in its entirety and replaced with the following:

3. Omnibus Account.

The parties agree that up to two omnibus accounts, each held in the name of the Nominee, may be maintained for those Plan assets directed for investment in the Funds (“Account” or “Accounts"). One such omnibus account may be maintained in connection with Plans for which ING Life is providing various recordkeeping and other administrative services, and the other such omnibus account may be maintained in connection with Plans for which ING Institutional is providing various recordkeeping and other administrative services. Alternatively, one Account may be maintained in connection with Plans for which both ING Life and ING Institutional shall provide such recordkeeping and administrative services. ING Life or ING Institutional, as service

agents for the Plans, shall facilitate purchase and sale transactions with respect to the Account in accordance with the Agreement.

3. Paragraphs 5 and 6 of the Agreement are hereby deleted in their entirety and replaced with the following:

5. Servicing Fees: The provision of shareholder and administrative services to the Plans shall be the responsibility of ING Financial, ING Life, ING Institutional, or the Nominee and shall not be the responsibility of Distributor. The Nominee will be recognized as the sole shareholder of Fund shares purchased under this Agreement. It is further recognized that there will be a substantial savings in administrative expense and recordkeeping expenses by virtue of having one shareholder rather than multiple shareholders. In consideration of the administrative savings resulting from such arrangement, Distributor agrees to pay or cause to be paid an annual fee as specified in Schedule B (attached), based on the average net assets invested in the Funds through ING Life’s or ING Institutional’s arrangements with Plans in each calendar quarter. Within thirty (30) days after the end of each calendar quarter Distributor shall provide ING Life or ING Institutional with a statement showing the aggregate value of ING Life’s or ING Institutional’s accounts for the preceding quarter and include therewith a payment to ING Life or ING Institutional for the compensation due ING Life in accordance with this paragraph.

6. 12b-1 Fees. To compensate ING Financial for its distribution of Fund Shares, Distributor shall make quarterly payments to ING Financial, as specified in Schedule B (attached), based on the average net assets invested in Fund shares through ING Life’s arrangements with Plans in each calendar quarter. Distributor will make such payments to ING Financial within thirty (30) days after the end of each calendar quarter. Each payment will be accompanied by a statement showing the calculation of the fee payable to ING Financial for the quarter and such other supporting data as may be reasonably requested by ING Financial.

4. The following is added as Section 13(d) to the Agreement:

(d) Representations of ING Institutional. ING Institutional represents and warrants:

(i) that it (1) is a limited liability company organized under the laws of the State of Delaware, (2) is in good standing in that jurisdiction, (3) is in material compliance with all applicable federal and state laws, (4) is duly licensed and authorized to conduct business in every jurisdiction where such license or authorization is required, and will maintain such license or authorization in effect at all times during the term of this Agreement, and (5) has full authority to enter into this Agreement and carry out its obligations pursuant to it terms; and

(ii) that it is authorized under the Plans to (1) provide administrative services to the Plans and (2) facilitate transactions in the Fund through the Account.

5. The following replaces Section 15(b) of the Agreement:

(b) Notices. All notices and other communications hereunder shall be given or made in writing and shall be delivered personally, or sent by telex, facsimile, express delivery or registered or certified mail, postage prepaid, return receipt requested, to the party or parties to whom they are directed at the following address, or at such other addresses as may be designated by notice from such party to all other parties.
