		NOW, THEREFORE, in consideration of the promises and mutual covenants hereinafter

replaced with the following paragraph:

		In consideration of the Sub-Administrator's acting as the servicing agent to the
		Funds on behalf of NBMI and for the performance of Administrative Services and other
		services to the Funds by the Sub-Administrator pursuant to this Agreement, NBMI shall
		pay the Sub-Administrator (i) a fee with respect to the Trust Class shares of each Fund
		(other than Xxxxxxxxx Xxxxxx Genesis Fund), calculated daily and paid monthly in
		arrears, equal to 0.35% (35 bps) per annum of the daily net asset value of the total
		number of such shares held in the Account; (ii) a fee with respect to the Trust Class

the Funds to restrict or prohibit further purchases or exchanges of Fund shares by an individual
Participant or contract owner who has been identified by the Funds as having engaged in transactions in
Fund shares that violate market timing policies established by the Funds. The parties shall use their best
efforts, and shall reasonably cooperate with each other to prevent future market timing and frequent
trading. In addition, the parties entered into a separate shareholder information agreement on April 16,

EXHIBIT I
ING Excessive Trading Policy as of January 1, 2007

Various business units of ING offer variable annuity, variable life insurance and retirement plan
products through which customers may invest directly or indirectly in one or more mutual funds.
Frequent purchases and redemptions of a fund's shares, such as those associated with "market
timing," can adversely affect the fund and the returns achieved by the fund's share-holders. As a
result, many of the funds that are available through ING's products are taking measures to protect the
fund and its shareholders from potentially harmful trading activity. These measures include
reserving the right to reject purchase requests from shareholders who are making frequent purchases
and redemptions of a fund's shares.

ING, as the provider of multi-fund products, has adopted a definition of "Excessive Trading" that is
intended to respond to a majority of the restrictions on such trading activity that have been adopted
by the various fund families. ING's current definition of Excessive Trading and our policy with
respect to such trading activity is outlined below.

1.	ING currently defines Excessive Trading as more than one purchase and sale of the same fund (including money market funds) within a thirty (30) day period. Each fund offered through ING's products, either by prospectus or stated policy, has adopted or may adopt its own definition of Excessive Trading. Therefore ING reserves the right, without prior notice, to modify its general definition or to develop another definition that may apply to a particular fund, product or individual, depending on the needs of a particular fund and/or state or federal regulatory requirements.

	A	purchase followed by one or more sales and then another purchase of the same fund, or a sale

	followed by one or more purchases and then another sale of the same fund would meet ING's definition of Excessive Trading. The following transactions are excluded when determining whether trading activity is excessive:

	• Purchases or sales of shares related to non-fund transfers (for example, new purchase

		payments, withdrawals and (loans);

	• Transfers associated with scheduled dollar cost averaging and scheduled rebalancing

		programs;

	• Purchases and sales of fund shares in the amount of $250 or less; and

	• Purchases and sales of funds that affirmatively permit short-term trading in their fund

		shares, and movement between such funds and the money market fund.

2.	ING actively monitors fund transfer and reallocation activity within its products to identify Excessive Trading.

3.	If ING determines that an individual has used one or more of its products to engage in Excessive Trading, ING will send that individual a one-time warning letter and place that individual on a watch list. According to the needs of the various business units, a copy of the warning letter may also be sent, as applicable, to the person(s) or entity authorized to initiate fund transfers or reallocations, the agent/registered representative or investment adviser for that individual.

4.	If ING determines that an individual has used one or more of its products to engage in Excessive Trading after having received a warning letter as described above, ING will send a second letter to the individual. This letter will state that the individual's ability to initiate fund transfers or reallocations through the Internet, facsimile, telephone calls to the company's service center, or other electronic trading medium that ING may make available from time to time ("Electronic Trading Privileges") has been suspended for a period of 6 months. All fund transfers or reallocations will then have to be initiated by providing written instructions to ING via regular U.S. mail. During the Suspension Period, "inquiry only" privileges will be permitted where and when possible.

5.	Following the 6 month suspension period, the Electronic Trading Privileges may again be restored, but ING will continue to monitor the fund transfer and reallocation activity. Any future Excessive Trading will result in an indefinite suspension of the Electronic Trading Privileges.

6.	ING may elect to limit fund trading or reallocation privileges with respect to any individual, with or without prior notice, if ING determines that the individual's trading activity is disruptive, regardless of whether the individual's trading activity fall within the definition of Excessive Trading set forth above.
