                           SELLING AND SERVICES AGREEMENT

THIS AGREEMENT, made and entered into as of this first day of July, 2000 by and
among Aetna Investment Services, Inc. (“AISI”), Aetna Life Insurance and Annuity Company
(“ALIAC”) (collectively, “Aetna”), American Century Services Corporation ("Fund Agent"), and
American Century Investment Services, Inc. (“Distributor”), acting as agent for the registered
open-end management investment companies whose shares are or may be underwritten by
Distributor (each a “Fund” or collectively the “Funds”).

WHEREAS, Distributor acts as principal underwriter for the Funds;

     WHEREAS, AISI distributes shares of investment companies to certain plans under
Sections 401 or 457 of the Internal Revenue Code of 1986, as amended ("Code"), custodial
accounts under Section 403(b)(7) or 408 of the Code, and certain nonqualified deferred
compensation arrangements (collectively, "Plans"); and

     WHEREAS, AISI wishes to make available as investment options under the Plans, one or
more of the Funds made available by Distributor from time to time, each of which is a series of
mutual fund shares registered under the Investment Company Act of 1940, as amended, and
issued by a registered investment company (collectively, the “Issuers”); and

     WHEREAS, ALIAC is an insurance company that provides various recordkeeping and
other administrative services to Plans; and

     WHEREAS, pursuant to the terms and conditions hereinafter set forth, Distributor desires
to make shares of the Funds available as investment options under the Plans and to retain ALIAC
to provide various administrative and shareholder services in connection with the investment by
the Plans in the Funds on behalf of the Distributor, and ALIAC is willing to furnish such
services.

NOW, THEREFORE, it is agreed as follows:

1. Transactions in the Funds.

Subject to the terms and conditions of this Agreement, Distributor will cause the Issuers
to make shares of the Funds available to be purchased, exchanged, or redeemed, by or on behalf
of the Plans through a single account per Fund (the “Accounts”) at the net asset value applicable
to each order. The Funds’ shares shall be purchased and redeemed on a net basis in such quantity
and at such time as determined by AISI to correspond with investment instructions received by
AISI from the Plans or Plan participants. Dividends and capital gains distributions will be
automatically reinvested in full and fractional shares of the Funds.

2. Investment of Plan Assets.

AISI represents that it is authorized under the Plans to implement the investment of Plan
assets in the name of an appropriately designated nominee of each Plan (“Nominee”) in shares of
investment companies or other investment vehicles specified by a sponsor, an investment
adviser, an administrative committee, or other fiduciary as designated by a Plan (“Plan
Representative”) upon the direction of a Plan participant or beneficiary (“Participant”). The
parties acknowledge and agree that selections of particular investment companies or other
investment vehicles are made by Plan representatives or Participants, who may change their
respective selections from time to time in accordance with the terms of the Plan.

3. Omnibus Account.

The parties agree that a single omnibus account held in the name of the Nominee shall be
maintained for those Plan assets directed for investment in the Funds (“Account”).

4.      Pricing Information, Orders, Settlement.

            (a) Distributor will make shares available to be purchased by the Nominee on behalf of
the Account at the net asset value applicable to each order; provided, however, that the Plans
meet the criteria for purchasing shares of the Funds at net asset value as described in the Funds’
prospectuses. Fund shares shall be purchased and redeemed on a net basis for such Plans in such
quantity and at such time determined by AISI or the Nominee to correspond with investment
instructions received by AISI from Plan Representatives or Participants.

            (b) Distributor agrees to furnish or cause to be furnished to AISI for each Fund: (i)
confirmed net asset value information as of the close of trading (currently 4:00 p.m., East Coast
time) on the New York Stock Exchange (“Close of Trading”) on each business day that the New
York Stock Exchange is open for business (“Business Day”) or at such other time as the net asset
value of a Fund is calculated as disclosed in the relevant then current prospectus(es) in a format
that includes the Fund’s name and the change from the last calculated net asset value, (ii)
dividend and capital gains information as it arises, and (iii) in the case of a fixed income fund,
the daily accrual or the distribution rate factor. Distributor shall provide or cause to be provided
to AISI such information by 6:30 p.m., East Coast time.

            (c) AISI, as agent for the Funds for the sole purposes expressed herein shall receive from
Plan Representatives or Participants for acceptance as of the Close of Trading on each Business
Day: (i) orders for the purchase of shares of the Funds, exchange orders, and redemption requests
and redemption directions with respect to shares of the Funds held by the Nominee
(“Instructions”), (ii) transmit to Distributor such Instructions no later than 9:00 a.m., East Coast
time on the next following Business Day, and (iii) upon acceptance of any such Instructions,
communicate such acceptance to the Plan Representatives or Plan Participants, as appropriate
(“Confirmation”). The Business Day on which such Instructions are received in proper form by
AISI and time stamped by the Close of Trading will be the date as of which Fund shares shall be
deemed purchased, exchanged, or redeemed as a result of such Instructions. Instructions

received in proper form by AISI and time stamped after the Close of Trading on any given
Business Day shall be treated as if received on the next following Business Day. AISI agrees that
all Instructions received by AISI, which will be transmitted to Distributor for processing as of a
particular Business Day, will have been received and time stamped prior to the Close of Trading
on that previous Business Day. The day as of which an order is executed by the Fund’s transfer
agent pursuant to the provisions set forth above is referred to herein as the “Trade Date.” All
orders are subject to acceptance or rejection by Distributor or the Funds or any one of them.

            (d) AISI will wire payment, or arrange for payment to be wired, for such purchase orders,
in immediately available funds, to a Fund custodial account or accounts designated by
Distributor, as soon as possible, but in any event no later than 4:00 p.m., East Coast time on the
Business Day following the Business Day as of which such purchase orders are made in
conformance with Section 4(c).

            (e) Distributor or its designees will wire payment, or arrange for payment to be wired, for
redemption orders, in immediately available funds, to an account or accounts designated by AISI,
as soon as possible, but in any event under normal conditions no later than 4:00 p.m. East Coast
time on the same Business Day as of which such redemption orders are received by the
Distributor in conformance with Section 4(c); provided, however, the Issuers reserve the right to
settle redemption transactions within the time period set forth in the applicable Funds’ then-
current prospectus. On any Business Day when the Federal Reserve Wire Transfer System is
closed, all communication and processing rules will be suspended for the settlement of orders.
Orders will be settled on the next Business Day on which the Federal Reserve Wire Transfer
System is open and the original Trade Date will apply.

            (f) In lieu of applicable provisions set forth in paragraphs 4(a) through 4(e) above, the
parties may agree to provide pricing information, execute orders and wire payments for purchases
and redemptions through National Securities Clearing Corporation’s Fund/SERV System, in
which case such activities will be governed by the provisions set forth in Exhibit A to this
Agreement.

            (g) Upon Distributor’s request, AISI shall provide copies of historical records relating to
transactions between the Funds and the Plan Representatives or Participants investing in such
Funds, written communications regarding the Funds to or from such persons, and other materials,
in each case, as may reasonably be requested to enable Distributor or any other designated entity,
including without limitation, auditors, investment advisers, or transfer agents of the Funds to
monitor and review the services being provided under this Agreement, or to comply with any
request of a governmental body or self-regulatory organization or a shareholder. AISI also agrees
that AISI will permit Distributor or the Funds, or any duly designated representative to have
reasonable access to AISI’s personnel and records in order to facilitate the monitoring of the
quality of the services being provided under this Agreement.

            (h) AISI shall assume responsibility as herein described for any loss to Distributor or to a
Fund caused by a cancellation or correction made to an Instruction by a Plan Representative or
Participant subsequent to the date as of which such Instruction has been received by AISI and

originally relayed to Distributor, and AISI will immediately pay such loss to Distributor or such
Fund upon AISI’s receipt of written notification, with supporting data.

(i) Distributor shall indemnify and hold Aetna harmless, from the effective date of this
Agreement, against any amount Aetna is required to pay to Plans, Plan Representatives, or
Participants due to: an incorrect calculation or reporting by Distributor of a Fund’s daily net asset
value, dividend rate, or capital gains distribution rate that is deemed to be material under the
pricing policy of the Fund’s Board of Directors or which Distributor otherwise deems necessary
to correct at the shareholder level... In addition, the Fund or the Distributor shall be liable to
Aetna for out of pocket costs incurred by Aetna in making a Plan’s or a Participant's account
whole, if such costs or expenses are a result of the Fund's failure to provide timely or correct net
asset values, dividend and capital gains or financial information and if such information is not
corrected by 4:00 p.m. East Coast time of the next business day after releasing such incorrect
information provided the incorrect NAV as well as the correct NAV for each day that the error
occurred is provided. If a mistake is caused in supplying such information or confirmations,
which results in a reconciliation with incorrect information, the amount required to make a Plan’s
or a Participant's account whole shall be borne by the party providing the incorrect information,
regardless of when the error is corrected.

(j) Each party shall notify the other of any errors or omissions in any information,
including a net asset value and distribution information set forth above, and interruptions in or
delay or unavailability of, the means of transmittal of any such information as promptly as
possible. AISI and Distributor agree to maintain reasonable errors and omissions insurance
coverage commensurate with each party’s respective responsibilities under this Agreement.

5. Servicing Fees.

The provision of shareholder and administrative services to the Plans, including, but not
limited to those specified in Exhibit D shall be the responsibility of AISI, ALIAC 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 to ALIAC servicing fees at
the annual rates set forth in Exhibit A. Distributor will make such payments to ALIAC within
thirty (30) days after the end of each calendar quarter. Payments shall be wired to: Wachovia
Bank Account Number 8732071464, ABA # 000000000, Reference: American Century Service /
12b-1 Fees, or as otherwise directed by Aetna in writing. Supporting documentation for payment
and such other data as may be reasonably requested by ALIAC shall be mailed to: Aetna
Financial Services, Inc., Attn: Central Valuation Xxxx, Xxxxxxxx XX00, 000 Xxxxxxxxxx Xxx.,
Xxxxxxxx, XX 00000. If required by a Plan or by applicable law, ALIAC shall have the right to
allocate to a Plan or to Participant accounts in a Plan all or a portion of such servicing fees, or to
use servicing fees it collects from Distributor to offset other fees payable by the Plan to Aetna.
The reimbursement set forth in Exhibit B is conditional upon the addition of Ultra (Advisor
Class) and Income and Growth (Advisor Class) to several Plans and/or products offered by Aetna

in October, 2000 (either to certain Plans pursuant to the terms of this Agreement or under
Variable Annuity Contracts pursuant to the terms of the Fund Participation Agreement between
Distributor and ALIAC dated as of July 1, 2000).

6. 12b-1 Fees.

To compensate AISI for its distribution services of Fund Shares including, but not limited
to those specified on Exhibit E, Distributor shall make quarterly payments to AISI as set forth in
Exhibit B or C. Distributor will make such payments to AISI within thirty (30) days after the end
of each calendar quarter. Payments shall be wired to: Wachovia Bank Account Number
8732071464, ABA # 000000000, Reference: American Century Service / 12b-1 Fees, or as
otherwise directed by Aetna in writing. Supporting documentation for payment and such other
data as may be reasonably requested by ALIAC shall be mailed to: Aetna Financial Services,
Inc., Attn: Central Valuation Xxxx, Xxxxxxxx XX00, 000 Xxxxxxxxxx Xxx., Xxxxxxxx, XX 00000.
If required by a Plan or by applicable law, AISI shall have the right to allocate to a Plan or to
Participant accounts in a Plan all or a portion of such 12b-1 fees, or to use 12b-1 fees it collects
from Distributor to offset other fees payable by the Plan to Aetna.

7.      Expenses.

            (a) Distributor shall provide Aetna with copies of each Issuer’s proxy materials, periodic
fund reports to shareholders and other materials that are required by law to be sent to the Issuers’
shareholders. In addition, Distributor shall provide Aetna with a sufficient quantity of
prospectuses of the Funds to be used in conjunction with the transactions contemplated by this
Agreement, together with such additional copies of the Issuers’ prospectuses as may be
reasonably requested by Aetna. If a Plan provides for pass-through voting by its Participants, or
if it determines that pass-through voting is required by law, Distributor will provide Aetna with a
sufficient quantity of proxy materials for each Participant under such Plan or Plans.

            (b) The cost of preparing, printing and bulk shipping to Aetna’s warehouse, or making
available through electronic medium, of the prospectuses, periodic fund reports and other
materials of the Issuers to Aetna for Aetna’s use in marketing shares of the Funds to Plans and
Participants shall be paid by Distributor or its agents or affiliates; provided, however, that if at
any time Distributor or its agent reasonably deems the usage by Aetna or a Plan of such items for
marketing purposes to be excessive, it may, prior to the delivery of any quantity of materials in
excess of what it deemed reasonable, request that Aetna or the Plan, as the case may be,
demonstrate the reasonableness of such usage. If Distributor believes the reasonableness of such
usage has not been adequately demonstrated, it may request that the party responsible for such
excess usage pay the cost of printing (including press time) and delivery of any excess copies of
such materials. Unless Aetna or the Plan, as the case may be, agrees to make such payments,
Distributor may refuse to supply such additional materials and Distributor shall be deemed in
compliance with this Section 7 if it delivers to Aetna at least the number of prospectuses and
other materials as may be required by the Issuers under applicable law.

(c) The cost of preparing, printing and distribution of prospectuses, periodic fund reports
and other materials of the Issuers to the Plans or Participants shall be paid by Aetna. The cost of
distribution of proxies to the Plans or Participants shall be paid by the Distributor.

8. Termination.

      This Agreement shall terminate as to the maintenance of the Account:

outstanding securities of the Funds;

the investment requirements of the Plans; provided, however, that prompt advance notice of

            (c) At the option of either AISI or Distributor, upon institution of formal disciplinary or
investigative proceedings against AISI, Distributor or the Funds by the National Association of

            (d) At the option of Distributor, if Distributor shall reasonably determine in good faith
that shares of the Funds are not being offered in conformity with the terms of this Agreement;

            (e) At the option of Aetna, upon termination of the Management Agreement between the
Fund and Adviser; written notice of such termination shall be promptly furnished to Aetna;

consent of all other parties hereto; provided, however, that AISI and ALIAC may assign, without
consent of Distributor, their respective duties and responsibilities under this Agreement to any of
their affiliates, and provided, further, that AISI or ALIAC may enter into subcontracts with other
dealers for the solicitation of sales of shares of the Funds without the consent of Distributor, or

            (g) If the Fund’s shares are not registered, issued or sold in conformance with federal law
or such law precludes the use of Fund shares as an investment vehicle for the Plans; provided,
however, that prompt notice shall be given by any party should such situation occur.

(h) By a vote of a majority of the independent directors of any Fund.

9. Continuation of Agreement.

such material is used with the general public or any Plan, Plan Representative, or Participant.
Distributor shall advise the submitting party in writing within a reasonable time period ofreceipt
of such materials, generally not expected to be more than five (5) Business Days, of its approval
or disapproval of such materials.

            (b) Distributor will provide to Aetna at least one complete copy of all prospectuses,
statements of additional information, annual and semiannual reports and proxy statements, other
related documents, and all amendments or supplements to any of the above documents that relate
to the Funds promptly after the filing of such document with the SEC or other regulatory
authorities.

            (c) Distributor will provide to Aetna, in electronic format, performance updates and
portfolio updates for the Funds as soon as reasonably practicable, assumed to be within 10

(a) Aetna agrees to indemnify and hold harmless the Funds, Distributor and each of their
directors, officers, employees, agents and each person, if any, who controls the Funds or their
investment adviser within the meaning of the Securities Act of 1933 (“1933 Act”) against any
losses, claims, damages or liabilities to which the Funds, Distributor or any such director, officer,
employee, agent, or controlling person may become subject, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) (i) arise out of, or are based upon, the
provision of administrative services by ALIAC under this Agreement, or (ii) result from a breach
of a material provision of this Agreement. Aetna will reimburse any legal or other expenses
reasonably incurred by Distributor or any such director, officer, employee, agent, or controlling
person in connection with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that Aetna will not be liable for indemnification hereunder to the
extent that any such loss, claim, damage, liability or action arises out of or is based upon the
gross negligence or willful misconduct of Distributor or any such director, officer, employee,
agent or any controlling person herein defined in performing their obligations under this
Agreement.

            (b) Distributor agrees to indemnify and hold harmless each of AISI and ALIAC, the
Nominee and each of their directors, officers, employees, agents and each person, if any, who
controls AISI and ALIAC and the Nominee within the meaning of the 1933 Act against any
losses, claims, damages or liabilities to which AISI or ALIAC, the Nominee, or any such
director, officer, employee, agent or controlling person may become subject, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) (i) arise out of or are based
upon any untrue statement of any material fact contained in the registration statement, prospectus

fact that is necessary to make the statements therein not misleading or (ii) result from a breach of
a material provision of this Agreement. Distributor will reimburse any legal or other expenses
reasonably incurred by AISI or ALIAC, the Nominee, or any such director, officer, employee,

hereunder to the extent that any such loss, claim, damage or liability arises out of, or is based
upon, the gross negligence or willful misconduct of AISI or ALIAC, the Nominee or their
respective directors, officers, employees, agents, or any controlling person herein defined in the
performance of their obligations under this Agreement.

commencement of action, such indemnified party will, if a claim in respect thereof is to be made
against the indemnifying party hereunder, notify the indemnifying party of the commencement
thereof, but the omission so to notify the indemnifying party will not relieve it from any liability
that it may have to any indemnified party otherwise than under this Section 12. In case any such
action is brought against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate therein and, to the
extent that it may wish to, assume the defense thereof, with counsel satisfactory to such
indemnified party, and after notice from the indemnifying party to such indemnified party of its
election to assume the defense thereof, the indemnifying party will not be liable to such
indemnified party under this Section 12 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof other than reasonable costs of
investigation.

            (d) If the indemnifying party assumes the defense of any such action, the indemnifying
party shall not, without the prior written consent of the indemnified parties in such action, settle
or compromise the liability of the indemnified parties in such action, or permit a default or
consent to the entry of any judgment in respect thereof, unless in connection with such
settlement, compromise or consent, each indemnified party receives from such claimant an
unconditional release from all liability in respect of such claim.

Procedures for Pricing and Order/Settlement Through National Securities Clearing
Corporation’s Mutual Fund Profile System and Mutual Fund Settlement, Entry and
Registration Verification System

1. As provided in Section 3(f) of the Selling and Services Agreement, the parties hereby agree to
provide pricing information, execute orders and wire payments for purchases and redemptions of
Fund shares through National Securities Clearing Corporation (“NSCC”) and its subsidiary systems
as follows:

(a) American Century Services Corporation (“Fund Agent”) will furnish to AISI or its affiliate
      through NSCC’s Mutual Fund Profile System (“MFPS”) (1) the most current net asset value
      information for each Fund, (2) a schedule of anticipated dividend and distribution payment
      dates for each Fund, which is subject to change without prior notice, ordinary income and
      capital gain dividend rates on the Fund’s ex-date, and (4) in the case of fixed income funds that
      declare daily dividends, the daily accrual or the interest rate factor. All such information shall
      be furnished to AISI or its affiliate by 6:30 p.m. Eastern Time on each business day that the
      Fund is open for business (each a "Business Day") or at such other time as that information
      becomes available. Changes in pricing information will be communicated to both NSCC and
      AISI or its affiliate.

(b) Upon receipt of Fund purchase, exchange and redemption instructions for acceptance as of the
      time at which a Fund's net asset value is calculated as specified in such Fund's prospectus
      ("Close of Trading") on each Business Day ("Instructions"), and upon its determination that
      there are good funds with respect to Instructions involving the purchase of Shares, AISI or its
      affiliate will calculate the net purchase or redemption order for each Fund. Orders for net
      purchases or net redemptions derived from Instructions received by AISI or its affiliate prior to
      the Close of Trading on any given Business Day will be sent to the Defined Contribution
      Interface of NSCC’s Mutual Fund Settlement, Entry and Registration Verification System
      (“Fund/SERV”) by 5:00 a.m. Eastern Time on the next Business Day. Subject to AISI’s or its
      affiliate’s compliance with the foregoing, AISI or its affiliate will be considered the agent of
      theFund Agent, and the Business Day on which Instructions are received by AISI or its affiliate
      in proper form prior to the Close of Trading will be the date as of which shares of the Funds are
      deemed purchased, exchanged or redeemed pursuant to such Instructions. Instructions received
      in proper form by AISI or its affiliate after the Close of Trading on any given Business Day will
      be treated as if received on the next following Business Day. Dividends and capital gains
      distributions will be automatically reinvested at net asset value in accordance with the Fund's
      then current prospectuses.

(c) AISI or its affiliate will wire payment for net purchase orders by the Fund Agent’s NSCC Firm
      Number, in immediately available funds, to an NSCC settling bank account designated by AISI
      or its affiliate no later than 5:00 p.m. Eastern time on the same Business Day such purchase
      orders are communicated to NSCC. For purchases of shares of daily dividend accrual funds,

      those shares will not begin to accrue dividends until the day the payment for those shares is
      received.

(d) NSCC will wire payment for net redemption orders by Fund, in immediately available funds, to
      an NSCC settling bank account designated by AISI or its affiliate, by 5:00 p.m. Eastern Time on
      the Business Day such redemption orders are communicated to NSCC, except as provided in a
      Fund's prospectus and statement of additional information.

(e) With respect to (c) or (d) above, if Fund Agent does not send a confirmation of AISI’s or its
      affiliate’s purchase or redemption order to NSCC by the applicable deadline to be included in
      that Business Day’s payment cycle, payment for such purchases or redemptions will be made
      the following Business Day.

(f)  If on any day AISI or its affiliate or Fund Agent is unable to meet the NSCC deadline for the
      transmission of purchase or redemption orders, it may at its option transmit such orders and
      make such payments for purchases and redemptions directly to Fund Agent or to AISI or its
      affiliate, as applicable, as is otherwise provided in the Agreement.

(g) These procedures are subject to any additional terms in each Fund's prospectus and the
      requirements of applicable law. The Funds reserve the right, at their discretion and without
      notice, to suspend the sale of shares or withdraw the sale of shares of any Fund.

2. AISI or its affiliate, Fund Agent and clearing agents (if applicable) are each required to have
entered into membership agreements with NSCC and met all requirements to participate in the
MFPS and Fund/SERV systems before these procedures may be utilized. Each party will be bound
by the terms of their membership agreement with NSCC and will perform any and all duties,
functions, procedures and responsibilities assigned to it and as otherwise established by NSCC
applicable to the MFPS and Fund/SERV system and the Networking Matrix Level utilized, except
that (i) we agree to conduct business on Networking Xxxxx 0 only; (ii) Section 12 of Article IV
relating to governing law is hereby amended by deleting the second sentence of such section; and
(iii)Section 13 of Article IV relating to arbitration of disputes is hereby deleted and shall be of no
force and effect.

3. Except as modified hereby, all other terms and conditions of the Agreement shall remain in full
force and effect. Unless otherwise indicated herein, the terms defined in the Agreement shall have
the same meaning as in this Exhibit.
