Exhibit 99-B.8.83 RULE 22C-2 AGREEMENT
This AGREEMENT, dated April 4, 2007, is effective as of the 16th day of October, 2007,
between American Century Investment Services, Inc. (the “Fund”) as principal underwriter for the
American Century family of mutual funds (the “Funds”) and ING Life Insurance and Annuity
Company, ING National Trust, ING USA Annuity and Life Insurance Company, ReliaStar Life
Insurance Company, ReliaStar Life Insurance Company of New York, Security Life of Denver
Insurance Company and Systematized Benefits Administrators Inc. (individually an “Intermediary”
and collectively the “Intermediaries”).
WHEREAS, the Intermediaries have adopted policies and procedures to monitor and deter
excessive trading activity within the mutual funds, including the Funds, available through the
variable annuity, variable life insurance and variable retirement plan products which they offer (the
“Variable Products”); and
WHEREAS, the Intermediaries' policies and procedures to monitor and deter excessive trading
activity within the mutual funds available through their Variable Products are attached hereto and
made part of this Agreement as Schedule A (the “Excessive Trading Policy”);
WHEREAS, the Fund desires for the Intermediaries to monitor and deter excessive trading
activity in the Funds in accordance with the Intermediaries' Excessive Trading Policy; and
WHEREAS, the parties desire to otherwise comply with the requirements under Rule 22c-2 of the
Investment Company Act of 1940, as amended (“Rule 22c-2”).
NOW, THEREFORE, in consideration of the mutual covenants herein contained, which
consideration is full and complete, the Fund and the Intermediaries hereby agree as follows:
A.	Agreement to Monitor and Deter Excessive Trading Activity,
	1.	The Intermediaries agree to monitor and deter excessive trading activity in the Funds
which are available through their Variable Products in accordance with the Intermediaries'
Excessive Trading Policy. Said Excessive Trading Policy may be amended from time to time with
the consent of the parties, which consent will not be unreasonably withheld.
	2.	The Intermediaries agree to provide the Fund the taxpayer identification number
(“TIN”), if requested, or any other identifying factor that would provide acceptable assurances of
the identity of all shareholders that are restricted to regular U.S. mail trading under the
Intermediaries^'Excessive Trading Policy.
B.	Agreement to Provide Shareholder Information.
	1.	Each Intermediary agrees to provide the Fund, upon written request, the following
shareholder information with respect to Covered Transactions involving the Funds:
		a.	The taxpayer identification number (“TIN”) or any other government issued
			identifier, if known, that would provide acceptable assurances of the identity
			of each shareholder that has purchased, redeemed, transferred or exchanged

			shares of a Fund through an account directly maintained by the
			Intermediaries during the period covered by the request;
		b.	The amount and dates of, and the Variable Product(s) associated with, such
			shareholder purchases, redemptions, transfers and exchanges; and
		c.	Any other data mutually agreed upon in writing.
	2.	Under this Agreement the term “Covered Transactions” are those transactions which
the Intermediaries consider when determining whether trading activity is excessive as described in
their Excessive Trading Policy.
	3.	Requests to provide shareholder information shall set forth the specific period for
which transaction information is sought. However, unless otherwise agreed to by the Intermediaries,
any such request will not cover a period of more than 90 consecutive calendar days from the date of
the request. The Fund may request transaction information older than 90 days from the date of the
request as it deems necessary to investigate compliance with policies established by the Fund for the
purpose of eliminating or reducing any dilution of the value of the outstanding shares issued by the
Fund, but shall not make a request for any information older than 12 months from the date of the
request.
	4.	Each Intermediary agrees to provide the requested shareholder information promptly
upon receipt of the request, but in no event later than 15 business days after receipt of such request,
provided that such information resides in its books and records. If shareholder information is not on
the Intermediary's books and records, the Intermediary agrees to use reasonable efforts to obtain and
transmit or have transmitted the requested information from the holder of the account.
C.	Agreement to Restrict Trading.
	1.	Each Intermediary agrees to execute written instructions from the Fund to restrict or
prohibit further Covered Transactions involving Fund shares by a shareholder who has been
identified by the Fund as having engaged in transactions in shares of a Fund (through an account
directly maintained by the Intermediary) that violate the policies and procedures established by the
Funds for the purposes of eliminating or reducing frequent trading of Fund shares.
	2.	Each Intermediary agrees to use reasonable efforts to execute or have executed (for
those shareholders whose information is not on the Intermediary's books and records) the written
instructions within 10 Business Days after actual receipt. The Intermediary will provide written
confirmation to the Fund as soon as reasonably practicable that such instructions have or have not
been executed. If the written instructions have not been executed, then the written confirmation will
also provide an explanation.
	3.	Instructions to restrict or prohibit further Covered Transactions involving Fund
shares must include:
		a.	The reason for requesting the restriction(s) and/or prohibition(s), supporting
			details regarding the transaction activity which resulted in the restriction(s)

		and/or prohibition(s)s and the applicable sections of the Fund's frequent
		trading policy and procedures that have been violated;
	b.	The specific restriction(s) and/or prohibition(s) to be executed, including the
		length of time such restriction(s) and/or prohibition(s) shall remain in place;
	c.	The TIN or any other government issued identifier, if known by the Fund, that
		would help the Intermediaries determine the identity of affected
		shareholder's); and
	d.	Whether such restriction(s) and/or prohibition(s) are to be executed in
		relation to all of the affected shareholder's Variable Products, only the type
		of Variable Product(s) through which the affected shareholder engaged in
		transaction activity which triggered the restriction(s) and/or prohibition(s) or
		in some other respect. In absence of direction from the Fund in this regard,
		restriction(s) and/or prohibition(s) shall be executed as they relate to the
		Intermediary's Variable Product(s) through which the affected shareholder
		engaged in the transaction activity which triggered the restriction(s) and/or
		prohibition(s).
D.	Limitation on Use of Information.
The Fund agrees neither to use the information received from the Intermediary for any purpose
other than to comply with SEC Rule 22c-2 and other applicable laws, rules and regulations, nor to
share the information with anyone other than its employees who legitimately need access to it.
Neither the Fund nor any of its affiliates or subsidiaries may use any information provided pursuant
to this Agreement for marketing or solicitation purposes. The Fund will take such steps as are
reasonably necessary to ensure compliance with this obligation.
The Fund shall indemnify and hold the Intermediaries, individually and collectively, (and any of
their respective directors, officers, employees, or agents) harmless from any damages, loss, cost, or
liability (including reasonable legal fees and the cost of enforcing this indemnity) arising out of or
resulting from any unauthorized use of or disclosure by the Fund of the information received from
the Intermediaries pursuant to this Agreement. In addition, because an award of money damages
(whether pursuant to the foregoing sentence or otherwise) may be inadequate for any breach of this
provision and any such breach may cause the Intermediaries irreparable harm, the Fund also agrees
that, in the event of any breach or threatened breach of this provision, the Intermediaries will also be
entitled, without the requirement of posting a bond or other security, to seek equitable relief,
including injunctive relief and specific performance. Such remedies will not be the exclusive
remedies for any breach of this provision but will be in addition to all other remedies available at
law or in equity to the Intermediaries.
In the event that the Fund is required by legal process, law, or regulation to disclose any information
received from the Intermediaries pursuant to this Agreement, the Fund shall provide Intermediaries
with prompt written notice of such requirement as far in advance of the proposed disclosure as
possible so that the Intermediaries (at their expense) may either seek a protective order or other

appropriate remedy which is necessary to protect their interests or waive compliance with this
provision to the extent necessary.
E.	Prior Agreements.
The parties acknowledge that prior to the effective date of this Agreement efforts to monitor and deter
excessive trading activity within the Variable Products were governed by whatever practices the
Fund and the Intermediaries agreed to follow in the absence of any formal agreement. The parties
also acknowledge having previously entered into fund participation and/or selling and service
agreements concerning the purchase and redemption of shares of Funds through the Variable
Products. The terms of this Agreement supplement the fund participation and/or selling and service
agreements and to the extent the terms of this Agreement conflict with the terms of the fund
participation and/or selling and service agreements, the terms of this Agreement will control. This
Agreement will terminate upon termination of the fund participation and/or selling and service
agreements.
F.	Notices.
	1.	Except as otherwise provided, all notices and other communications hereunder shall
be in writing and shall be sufficient if delivered by hand or if sent by confirmed facsimile or e-mail, or

Schedule A
ING “Excessive Trading” Policy
The ING family of insurance companies (“ING”), as providers of multi-fund variable insurance and
retirement products, has adopted this Excessive Trading Policy to respond to the demands of the
various fund families which make their funds available through our variable insurance and
retirement products to restrict excessive fund trading activity and to ensure compliance with Section
22c-2 of the Investment Company Act of 1940, as amended. ING's current definition of Excessive
Trading and our policy with respect to such trading activity is outlined below.
1.	ING actively monitors fund transfer and reallocation activity within its variable insurance and
	retirement products to identify Excessive Trading.
	ING currently defines Excessive Trading as:
	a.	More than one purchase and sale of the same fund (including money market funds)
		within a 60 calendar day period (hereinafter, a purchase and sale of the same fund is
		referred to as a “round-trip”). This means two or more round-trips involving the same
		fund within a 60 calendar day period would meet ING's definition of Excessive
		Trading; or
	b.	Six round-trips within a twelve month period.
	The following transactions are excluded when determining whether trading activity is excessive:
	a.	Purchases or sales of shares related to non-fund transfers (for example, new purchase
		payments, withdrawals and loans);
	b.	Transfers associated with scheduled dollar cost averaging, scheduled rebalancing or
		scheduled asset allocation programs;
	c.	Purchases and sales of fund shares in the amount of $5,000 or less;
	d.	Purchases and sales of funds that affirmatively permit short-term trading in their fund
		shares, and movement between such funds and a money market fund; and
	e.	Transactions initiated by a member of the ING family of insurance companies.
2.	If ING determines that an individual has made a purchase of a fund within 60 days of a prior
	round-trip involving the same fund, ING will send them a letter warning that another sale of that
	same fund within 60 days of the beginning of the prior round-trip will be deemed to be
	Excessive Trading and result in a six month suspension of their ability to initiate fund transfers
	or reallocations through the Internet, facsimile, Voice Response Unit (VRU), telephone calls to
	the ING Customer Service Center, or other electronic trading medium that ING may make
	available from time to time (“Electronic Trading Privileges”). Likewise, if ING determines that
	an individual has made five round-trips within a twelve month period, ING will send them a letter
	warning that another purchase and sale of that same fund within twelve months of the initial
	purchase in the first round-trip in the prior twelve month period will be deemed to be Excessive
	Trading and result in a six month suspension of their Electronic Trading Privileges. According
	to the needs of the various business units, a copy of the warning letters 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. A copy of the warning
	letters and details of the individual's trading activity may also be sent to the fund whose shares
	were involved in the trading activity.

A-1

3.	If ING determines that an individual has used one or more of its products to engage in
	Excessive Trading, ING will send a second letter to the individual. This letter will state that the
	individual's Electronic Trading Privileges have been suspended for a period of six months.
	Consequently, all fund transfers or reallocations, not just those which involve the fund whose
	shares were involved in the Excessive Trading activity, will then have to be initiated by providing
	written instructions to ING via regular U.S. mail. During the six month suspension period,
	electronic “inquiry only” privileges will be permitted where and when possible. A copy of the
	letter restricting future transfer and reallocation activity to regular U.S. mail and details of the
	individual's trading activity may also be sent to the fund whose shares were involved in the
	Excessive Trading activity.
4.	Following the six month suspension period during which no additional Excessive Trading is
	identified, Electronic Trading Privileges may again be restored. ING will continue to monitor
	the fund transfer and reallocation activity, and any future Excessive Trading will result in an
	indefinite suspension of the Electronic Trading Privileges. Excessive Trading activity during the
	six month suspension period will also result in an indefinite suspension of the Electronic
	Trading Privileges.
5.	ING reserves the right 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 falls within the definition of
	Excessive Trading set forth above. Also, ING's failure to send or an individual's failure to
	receive any warning letter or other notice contemplated under this Policy will not prevent ING
	from suspending that individual's Electronic Trading Privileges or taking any other action
	provided for in this Policy.
6.	Each fund available through ING's variable insurance and retirement products, either by
	prospectus or stated policy, has adopted or may adopt its own excessive/frequent trading policy.
	ING reserves the right, without prior notice, to implement restrictions and/or block future
	purchases of a fund by an individual who the fund has identified as violating its
	excessive/frequent trading policy. All such restrictions and/or blocking of future fund purchases
	will be done in accordance with the directions ING receives from the fund.
