                  WHEREAS, RSI Retirement Trust ("Trust"), a trust organized and
existing pursuant to an Agreement and Declaration of Trust, made as of October
22, 1940, as amended from time to time ("Agreement and Declaration of Trust")

("Unitholders") in the Trust;

                  WHEREAS, the Trust is an investment company registered under
the Investment Company Act of 1940, as amended (the "Act"); and

                  WHEREAS, the Trustees of the Trust ("Trustees") are vested
with authority for the management and control of the assets of the Trust in
accordance with the provisions of the Agreement and Declaration of Trust and in
furtherance of such authority are vested with the power to designate an
investment manager or managers (as defined in the Employee Retirement Income
Security Act of 1974, as amended ("ERISA")) to manage (including the power to
acquire and dispose of) the assets of any of the Investment Funds (as defined in
the Agreement and Declaration of Trust) of the Trust; and

                  WHEREAS, the Trust and the Manager have entered into an
Investment Management Agreement dated June 7, 2004, pursuant to which the
Manager may designate Sub-Advisers to perform certain investment advisory
functions under the supervision of the Manager and the Trustees; and

<PAGE>

the Sub-Adviser is willing to act in such capacity in accordance with the
provisions of this Agreement;

                  NOW, THEREFORE, the Manager hereby agrees with the Sub-Adviser
as follows:
                  1. Appointment of the Sub-Adviser

                  A. The Manager hereby designates, appoints, engages and
retains the Sub-Adviser as investment manager of the assets comprising the
Investment Fund of the Trust referred to on Schedule A hereto ("Investment
Fund") or such portion thereof as shall be designated by the Manager (the
"Account").

                  B. The Sub-Adviser hereby accepts appointment to manage the
assets of the Account.

                  C. The term of this Agreement shall commence on the effective
date stated above for a period of two years and shall continue in effect
thereafter from year to year provided that such continuance is specifically
approved annually in the manner required by the Act.

                  D. The Manager represents and warrants that (i) it is duly
authorized to enter into this Agreement with Sub-Adviser, (ii) that
authorizations granted by the Manager to Sub-Adviser do not violate any
documents governing the Manager, and (iii) that any notification to Sub-Adviser
of any and all changes to the investment objectives or policies, will comply
with any laws and regulations applicable to the Manager.

                  E. The Sub-Adviser and Manager understand that the Investment
Fund is being managed in a "manager-of-managers" style, and understand and agree
that, pursuant to that management style, the Manager will, among other things:
(1) continually evaluate the performance of the Sub-Adviser and any other
subadvisers to the Investment Fund through quantitative and qualitative analysis
and consultations with the Sub-Adviser and other subadvisers, if any, (2)
periodically make recommendations to the Trustees as to whether the contract
with one or more subadvisers should be renewed, modified, or terminated, and (3)
periodically report to the Trustees regarding the results of its evaluation and
monitoring functions. The Sub-Adviser acknowledges that its services may be
modified or terminated pursuant to this process.

                  2. Assets of the Account

                  The Manager shall certify or cause to be certified to the
Sub-Adviser the assets comprising the Account as of the commencement of the term
of this Agreement. The Manager may add to the Account assets acceptable to the
Sub-Adviser or withdraw assets from the Account at any time or from time to time
by notification to the Sub-Adviser. The Account shall consist of the assets
certified to the Sub-Adviser as aforesaid, or any assets into which the same may
be converted from time to time, together with any income therefrom or any other
increment thereon and assets added as aforesaid, less assets withdrawn as
aforesaid.

                                       2
<PAGE>

                  3. Investment Powers

                  A. Subject to the provisions of paragraph B of this Section 3,
the Sub-Adviser shall have exclusive authority and discretion, subject to and
consistent with the investment objectives and policies of the Investment Fund as
set forth in the current Prospectus of the Trust delivered to the Sub-Adviser
("Prospectus") and as specified in writing from time to time by the Trustees or
the Manager and delivered to the Sub-Adviser, to manage (including the power to
acquire and dispose of) the assets of the Account.

                  B. Notwithstanding the provisions of paragraph A of this
Section 3, it is understood and agreed that a portfolio lending agent, other
than the Sub-Adviser, may lend securities from the Account and may invest assets
of the Account on a temporary basis pending permanent investment or
distribution, and the Sub-Adviser shall have no liability or responsibility with
respect to the exercise of such authority by such other portfolio lending agent.

                  C. The Sub-Adviser shall consult with the Manager or the
Trustees at such times as the Manager or the Trustees shall reasonably request
with respect to the overall investment policy of the Account, and with the
instructions and directions of the Manager and of the Trustees, co-operate with
the Manager's (or its designee's) personnel responsible for monitoring the
Investment Fund's compliance with and will conform to and comply with, the
requirements of the Act, the Internal Revenue Code of 1986, as amended, and all
other applicable federal and state laws and regulations including, among other
things, the preparation and filing of such reports as are, or may in the future
be, required by the Securities and Exchange Commission (the "Commission").

                  D. In providing its services, Sub-Adviser may rely on the
financial information, governing documents and amendments thereto provided by
the Manager to Sub-Adviser without Sub-Adviser having any duty or obligation to
investigate the accuracy or completeness of the information, documents or
amendments. Sub-Adviser does not guarantee the investment performance of any
investment in the Account.

                  E. The Sub-Adviser acknowledges that it may not consult with
any other subadviser to the Investment Fund, including any other subadviser that
is a principal underwriter or an affiliated person of a principal underwriter,
concerning transactions of the Investment Fund in securities or other assets.

                  4. Standard of Care

                  A. The Sub-Adviser shall invest the assets of the Account in
the manner provided herein and shall have no duty or responsibility with respect
to the diversification of the assets of the Trust, except with respect to the
diversification of the assets of the Account as contemplated by the Prospectus.

                                       3
<PAGE>

                  B. The Sub-Adviser will be under no liability or obligation to
anyone with respect to any failure on the part of the Manager or any other
investment manager to perform any of their obligations under any agreement
affecting the Account or under the terms of this Agreement or for any error or
omission whatsoever on the part of the Manager or any other investment manager.

                  C. The Sub-Adviser shall not be liable for the making,
retention or sale of any investment or reinvestment made by it as herein
provided, nor for any loss to or diminution of the value of the property of the
Account; provided, however, that the Sub-Adviser has acted in the premises with
the care, skill, prudence, and diligence under the circumstances then prevailing
that a prudent man acting in like capacity and familiar with such matters would
use in the conduct of any enterprise of a like character and with like aims;
provided, further, however, that nothing in this Agreement shall protect the
Sub-Adviser against any liability to the Manager, the Trust or Unitholders to
which the Sub-Adviser would otherwise be subject by reason of willful
misfeasance, bad faith or gross negligence in the performance of its duties
hereunder or by reason of its reckless disregard of its obligations and duties
hereunder. Furthermore, nothing in this Agreement shall be deemed to waive any
rights the Manager or the Investment Fund may have against the Sub-Adviser under
federal or state securities laws. The Sub-Adviser and the Manager shall
indemnify each other, and any affiliated persons, officers, directors and
employees, for any liabilities and expenses, including attorneys' fees, which
may be sustained as a result of the other party's willful misfeasance, bad
faith, gross negligence, or reckless disregard of its duties hereunder or
violation of applicable law, including, without limitation, the Act and federal
and state securities laws.

                  5. General Provisions

                  A. Compensation for the services of the Sub-Adviser will be as
set forth in Schedule A hereto.

                  B. The Manager understands that: (i) Sub-Adviser acts as
adviser to other clients and may publish or give advice and take action with
respect to any other client, which may differ from the timing or nature of any
action taken by Sub-Adviser with respect to the Account; (ii) Sub-Adviser will
not have any obligation to purchase or sell, or to recommend for purchase or
sale, by the Account any securities that Sub-Adviser, its principals, affiliates
or employs may purchase or sell for any other client or themselves if, in their
reasonable opinion, such transaction appears inadvisable for the Account; and
(iii) transactions in a specific security may not be accomplished for all
clients at the same time at the same price.

                  C. With respect to securities in the Account, the Sub-Adviser
shall purchase such securities from or through and sell such securities to or
through such persons, brokers or dealers as the Sub-Adviser shall deem
appropriate to carry out the policy with respect to brokerage as set forth in
the Prospectus or as the Manager or the Trustees of the Trust may direct from
time to time. In providing the Account with investment supervision, it is
recognized that

                                       4
<PAGE>

the Sub-Adviser will give primary consideration to securing the most favorable
price and efficient execution. The Sub-Adviser shall have discretion to effect
investment transactions for the Investment Fund through broker-dealers
(including, to the extent legally permissible, broker-dealers affiliated with
the Sub-Adviser) qualified to obtain best execution of such transactions who
provide brokerage and/or research services, as such services are defined in
Section 28(e) of the Exchange Act of 1934, as amended (the "Exchange Act"). It
is understood that it is desirable for the Trust that the Sub-Adviser have
access to supplemental research and security and economic analysis and
statistical services and information with respect to the availability of
securities or purchasers or sellers of securities provided by brokers and of use
to the Trust although such access may require the allocation of brokerage
business to brokers who execute transactions at a higher cost to the Trust than
other brokers who provide only execution of portfolio transactions, provided
that the research, analysis, services and information provided by such brokers,
viewed in light of either that particular investment transaction or the overall
responsibilities of the Sub-Adviser with respect to the Investment Fund and
other accounts as to which it may exercise investment discretion (as such term
is defined in Section 3(a)(35) of the Exchange Act), are reasonable in relation
to the higher cost. Therefore, the Sub-Adviser is authorized to place orders for
the purchase and sale of securities with such brokers, subject to review by the
Manager from time to time with respect to the extent and continuation of this
practice. It is understood that the services provided by such brokers may be
useful to the Sub-Adviser in connection with its services to other clients.

                     On occasions when the Sub-Adviser deems the purchase or
sale of a security or futures contract to be in the best interest of the
Investment Fund as well as other clients of the Sub-Adviser, the Sub-Adviser, to
the extent permitted by applicable laws and regulations, may, but shall be under
no obligation to, aggregate the securities or futures contracts to be sold or
purchased in order to obtain the most favorable price or lower brokerage
commissions and efficient execution. In such event, allocation of the securities
or futures contracts so purchased or sold, as well as the expenses incurred in
the transaction, will be made by the Sub-Adviser in the manner the Sub-Adviser
considers to be the most equitable and consistent with its fiduciary obligations
to the Investment Fund and to such other clients.

                  D. This Agreement shall automatically terminate in the event
of its "assignment" (as that term is defined in the Act) or upon termination of
the Investment Management Agreement between the Trust and the Manager. The
Sub-Adviser agrees that it will promptly notify the Trust and the Manager of the
occurrence or anticipated occurrence of any event that would result in the
assignment of this Agreement, including, but not limited to, a change or
anticipated change in control (as defined in the Act) of the Sub-Adviser;
provided that the Sub-Adviser need not provide notice of such an anticipated
event before the anticipated event is a matter of public record.

                  E. This Agreement may be terminated, without the payment of
any penalty, by either party hereto or by the Trust on not more than sixty (60)
days' nor less than thirty (30) days' written notice delivered or mailed by
registered mail, postage prepaid, to the other party; any such termination on
behalf of the Trust to be pursuant to a vote of the Trustees or by a vote of a
majority of the outstanding voting securities (as defined in the Act) of the
Investment Fund.

                                       5
<PAGE>

                  F. The Sub-Adviser shall maintain all books and records with
respect to the Investment Fund's portfolio transactions effected by it as
required by subparagraphs (b)(5), (6), (7), (9), (10) and (11) and paragraph (f)
of Rule 31a-1 under the Act, and shall furnish to the Investment Fund's Board of
Trustees such periodic and special reports as the Trustees may reasonably
request. The Sub-Adviser shall make reasonably available its employees and
officers for consultation with the Trustees or officers or employees of the
Manager with respect to any matter discussed herein, including, without
limitation, the valuation of the Investment Fund's securities.

                  G. The Sub-Adviser or an affiliate shall provide the
Investment Fund's custodian on each business day with information relating to
all transactions concerning the portion of the Investment Fund's assets it
manages, and shall provide the Manager with such information upon request of the
Manager.

                  H. The Sub-Adviser shall keep the Investment Fund's books and
records required to be maintained by the Sub-Adviser pursuant to this Agreement
and shall timely furnish to the Manager all information relating to the
Sub-Adviser's services hereunder needed by the Manager to keep the other books
and records of the Investment Fund required by Rule 31a-1 under the Act or any
successor regulation. The Sub-Adviser agrees that all records which it maintains
for the Investment Fund are the property of the Investment Fund, and the
Sub-Adviser will surrender promptly to the Investment Fund any of such records
upon the Investment Fund's request; provided, however, that the Sub-Adviser may
retain a copy of such records. The Sub-Adviser further agrees to preserve for
the periods prescribed by Rule 31a-2 of the Commission under the Act or any
successor regulation any such records as are required to be maintained by it
pursuant to this Agreement.

                  I. The Sub-Adviser may rely on the authenticity, truth and
accuracy of, and will be fully protected in acting upon:

                  (a) Any notice, direction, certification, approval or
                      other writing of the Manager, if evidenced by an
                      instrument signed by the President, a Vice President,
                      the Treasurer or the Assistant Treasurer of the
                      Manager;

                  (b) Any copy of a resolution of the Trustees, if
                      certified by the Secretary of the Trust;

                  (c) Any notification or information provided by the
                      custodian of the assets in the Account, if evidenced
                      by an instrument signed by an officer of the
                      custodian;

                  (d) Any instruction reasonably believed to be genuine and
                      to be given by the Manager or the Trustees or its or
                      their authorized delegate or by the custodian or any
                      other investment manager.

                  J. The Sub-Adviser may rely on, and will be fully protected
with respect to any action taken or omitted in reliance on, any information,
statement or certificate delivered to the Sub-Adviser by the Manager or the
Trustees with respect to any matter concerning the Trust

                                       6
<PAGE>

and the operation and administration of the Account. The Sub-Adviser is
expressly authorized to consult with the Manager with respect to any matters
arising in the administration of the Account and to act on the advice of the
Manager, provided nothing herein shall limit the full responsibility of the
Sub-Adviser for the management of the assets of the Account as provided herein.

                  K. Communications from the Sub-Adviser to the Manager shall be
addressed to:

                            Retirement System Investors Inc.
                            317 Madison Avenue
                            New York, New York 10017
                            Attn.:  Stephen P. Pollak
                            Executive Vice President, Counsel and Secretary

Communications to the Sub-Adviser from the Manager or the Trustees shall be
addressed to the address set forth in Schedule A hereto. In the event of a
change of address, communications shall be addressed to such new address as
designated in a written notice from the Manager, the Trustees or the
Sub-Adviser, as the case may be. All communications addressed in the above
manner and by certified mail or delivered by hand shall be sufficient under this
Agreement.

                  L. Unless the Manager or the Trustees instructs the
Sub-Adviser otherwise in writing, the Sub-Adviser will vote proxies for
securities and investments held in the Account in accordance with the
Sub-Adviser's written policies for proxy voting. Manager recognizes that
Sub-Adviser out-sources its proxy voting to Institutional Shareholder Services
(ISS) and has adopted and will generally vote in accordance with their policies
and procedures. However, Sub-Adviser will not vote in "blocking nations" since
Sub-Adviser does not believe it is in the best interest of its clients to
participate in proxies where voting restricts Manager's ability to sell or
otherwise dispose of their equity interest. Sub-Adviser will report on all
proxies voted but will not report on instances in which voting does not occur
(this applies to "blocking nations" as discussed in the preceding sentence). The
Manager agrees to forward, or to instruct the custodian to forward, to the
Sub-Adviser copies of all proxies and shareholder communications relating to
securities and investments held in the Account. The Manager agrees that the
Sub-Adviser will not be liable for failing to vote any proxies where it has not
received such proxies or related shareholder communications on a timely basis.
The Sub-Adviser will not be responsible for taking any action or rendering any
advice with respect to any legal proceedings or bankruptcies involving the
issuers of securities and investments held in the Account.

                  M. The Manager shall consider all reports, opinions,
analytical surveys, financial statements, or other documents ("Reports")
provided by Sub-Adviser in connection with its investment advisory and portfolio
services and this Agreement as confidential. All Reports are intended only for
the Manager's information and for the sole use of the Manager. The Manager
expressly agrees that it will not share such reports with any third parties. The
above representations shall not, however, restrict in any way the Manager's
ability to exhibit such Reports to the Manager's Board of Directors, the Trust's
Board of Trustees and to

                                       7
<PAGE>

regulators. Sub-Adviser shall keep confidential information provided by Manager
that is marked confidential or by the type of information or method of delivery
a reasonable person would consider the information confidential. Sub-Advisor is
authorized to mention Manager in its list of clients.

                  N. In connection with its duties under this Agreement, the
Sub-Adviser agrees to maintain adequate compliance procedures to ensure its
compliance with the Act, the Investment Advisers Act of 1940, and other
applicable federal and state laws and regulations.

                  O. All agreements hereunder will be governed by the laws of
the State of New York, without reference to such State's conflict of law rules.
Any question of interpretation of any term or provision of this Agreement having
a counterpart in or otherwise derived from a term or provision of the Act, shall
be resolved by reference to such term or provision of the Act and to
interpretations thereof, if any, by the United States courts or, in the absence
of any controlling decision of any such court, by rules, regulations or orders
of the Commission issued pursuant to the Act. In addition, where the effect of a
requirement of the Act, reflected in any provision of this Agreement, is
implemented, clarified or interpreted by rules, regulation or order of the
Commission, such provision shall be deemed to incorporate the effect of such
rule, regulation or order.

                  P. No term or provision of this Agreement may be amended,
modified or waived without the affirmative vote or action by written consent of
the Trustees and the written agreement of the Manager and the Sub-Adviser and in
accordance with the requirements of the Act.

                  Q  This Agreement constitutes the entire understanding and
agreement of the parties hereto.

                  R. Each provision and agreement herein defined shall be
treated as separate and independent from any other provision or agreement
herein, and shall be enforceable notwithstanding the unenforceability of any
such other provision or agreement.

6.  Electronic Delivery

    The Manager hereby consents to receiving the following (hereinafter the
"Documents") via electronic mail ("e-mail") during the term of this Agreement
with Sub-Adviser:

                              RSI RETIREMENT TRUST
                        INVESTMENT SUB-ADVISORY AGREEMENT

Name of Sub-Adviser:    Julius Baer Investment Management LLC

Address:                330 Madison Avenue
                        New York, NY 10017
Attention:              Hendricus Bocxe/Barney Walker

Investment Fund:        International Equity Fund

Compensation Terms:

Terms used herein shall have the meaning used in the Investment Sub-Advisory
Agreement between the Manager and the Sub-Adviser ("Agreement"). The Manager
agrees to pay to the Sub-Adviser, as full compensation and reimbursement for the
services to be rendered pursuant to the Agreement and any expenses incurred in
connection therewith, a fee at the end of each fiscal quarter of the Trust,
computed by applying the following rate to that portion of the assets of the RSI
Retirement Trust's portfolio managed by the Sub-Adviser:

                  Effective July 26, 2004, 0.80% on the first $20
                  million of assets, 0.60% on the next $20 million of
                  assets, 0.50% on the next $60 million of assets, and
                  0.40% on assets in excess of $100 million.

Billing is done for each quarter on the basis of services performed during that
particular quarter. The quarterly fee is calculated on the basis of the average
of the asset value as of the last day of each month of each calendar quarter,
equal to one-fourth of the annual rate.

If the Agreement commences on a date other than on the beginning of any such
quarterly period or terminates on a date other than the end of any such
quarterly period, the fee payable hereunder shall be proportionately reduced
according to the number of days during such period services were not rendered by
the Sub-Adviser.

                                  11

IN WITNESS WHEREOF, the parties to the Agreement have executed this Schedule A,
effective as of July 26 , 2004.

                  THIS AGREEMENT effective as of October 1, 2004 is entered into

                              W I T N E S S E T H:
                              - - - - - - - - - -

                  WHEREAS, RSI Retirement Trust (the "Trust"), a trust organized
and existing pursuant an Agreement and Declaration of Trust, made as of October
22, 1940, as amended from time to time ("Agreement and Declaration of Trust"),
which provides benefits for the employees (and their beneficiaries) of savings
institutions, related organizations, other corporate entities which have
established plans of participation and individual retirement accounts
("Unitholders") in the Trust; and

                  WHEREAS, the Trust is an investment company registered under
the Investment Company Act of 1940, as amended (the "Act"); and

                  WHEREAS, the Trustees of the Trust ("Trustees") are vested
with authority for the management and control of the assets of the Trust in
accordance with the provisions of the Agreement and Declaration of Trust and in
furtherance of such authority are vested with the power to designate an
investment manager or managers (as defined in the Employee Retirement Income
Security Act of 1974, as amended ("ERISA")) to manage (including the power to
acquire and dispose of) the assets of any of the Investment Funds (as defined in
the Agreement and Declaration of Trust) of the Trust; and

                  WHEREAS, the Trust and the Adviser have entered into an
Investment Management Agreement dated June 4, 2004, pursuant to which the
Adviser may designate Sub-Advisers to perform certain investment advisory

<PAGE>

                  WHEREAS, the Trust and the Manager have previously entered
into an Investment management Agreement dated as of September 15, 2003, under
which the Manager manages a portion of the assets of the Trust, serving as a
sub-adviser to the Adviser; and

                  WHEREAS, the Adviser wishes to appoint the Manager to continue
to manage a portion of the assets of the Trust, to act in such a capacity in the
manner set forth in this Agreement, and the Manager is willing to act in such
capacity in accordance with the provisions of this Agreement;

                  NOW, THEREFORE, the Trust hereby agrees with the Manager as
follows

1.       Appointment of the Manager

                  A. The Adviser hereby designates, appoints, engages and
retains the Manager as investment manager of the assets comprising the
Investment Fund of the Trust referred to on Schedule A hereto ("Investment
Fund"). The portion thereof to be managed by the Manager ("Account") shall be
designated by the Adviser.

                  B. The Adviser represents and warrants that it has the
authority to enter into this Investment Management Agreement with the Manager
pursuant to a vote of Trust unitholders, cast at a meeting called for the
purpose of voting on such approval, of a majority of the Trustees of the Trust
who are not parties to this Agreement or interested persons of any such party
and the provisions of Rule 15a-4 under the Act.

                  C. The Manager hereby accepts appointment to manage the assets
of the Account. The Manager hereby represents and warrants that it is a
qualified investment manager, as defined in Section 3(38) of ERISA, without
regard to subpart (c) of said Section. The Manager agrees that although it may
not be subject to the provisions of Title I of ERISA in carrying out its duties
and responsibilities under this Agreement, it shall act in accordance with the
requirements of Part 4 of ERISA as applicable to fiduciaries as defined under
ERISA. Notwithstanding anything contained herein to the contrary, references to
ERISA in this Agreement shall be deemed to contemplate all judicial or
administrative interpretations and all statutory and administrative exemptions
which would be applicable in the circumstances and to the parties in question
were this Agreement subject to ERISA.

                  D. The term of this Agreement shall commence on the effective
date hereof and shall continue thereafter for a period of one year from the date
hereof and thereafter from year to year provided that such continuance is
approved annually in the manner required by the Act.

                  E. The Manager and Adviser understand that the Investment Fund
is being managed in a "manager-of-managers" style, and understand and agree
that, pursuant to that management style, the Adviser will, among other things:
(1) continually evaluate the performance of the Manager and any other
subadvisers to the Investment Fund through quantitative and qualitative analysis
and consultations with the Manager and other subadvisers, if any, (2)
periodically make recommendations to the Trustees as to whether the contract
with one or more subadvisers should be renewed, modified, or terminated, and (3)
periodically report to the Trustees

                                       2
<PAGE>

regarding the results of its evaluation and monitoring functions. The Manager
acknowledges that its services may be modified or terminated pursuant to this
process.

                  2. Assets of the Account

                  The Adviser shall certify or cause to be certified to the
Manager the assets comprising the Account as of the commencement of the term of
this Agreement. The Adviser may add to the Account assets acceptable to the
Manager or withdraw assets from the Account at any time or from time to time by
notification to the Manager. The Account shall consist of the assets certified
to the Manager as aforesaid, or any assets into which the same may be converted
from time to time, together with any income therefrom or any other increment
thereon and assets added as aforesaid, less assets withdrawn as aforesaid.
Nothing contained in this Agreement shall be deemed to authorize the Manager to
act as the Account's custodian, or take or receive physical possession of any
assets comprising the Account.

                  3. Investment Powers

                  A. Subject to the provisions of paragraph B. of this Section
3, the Manager shall have exclusive authority and discretion, subject to and
consistent with the investment objectives and policies of the Investment Fund as
set forth in the current Prospectus of the Trust delivered to the Manager
("Prospectus") and as specified in writing from time to time by the Trustees or
the Adviser and accepted by the Manager, to manage (including the power to
acquire and dispose of) the assets of the Account, and, without limiting the
generality of the foregoing, to direct the Trustees in the exercise of the
powers relating to the Account which are specified in the Agreement and
Declaration of Trust as subject to such direction.

                  B. Notwithstanding the provisions of paragraph A. of this
Section 3, it is understood and agreed that an investment manager other than the
Manager may lend securities from the Account and may invest assets of the
Account on a temporary basis pending permanent investment or distribution, and,
to the extent not inconsistent with ERISA, the Manager shall have no liability
or responsibility with respect to the exercise of such authority by such other
investment manager; provided, however, that the Manager shall coordinate the
exercise of its authority hereunder which may be affected by the exercise of
such authority by the other investment manager in such manner appropriate to the
exercise of its authority as shall be agreed upon by the Manager and such other
investment manager. The Adviser will advise the Manager of any arrangement with
respect to any proposed lending of securities from the Account.

                  C. The Manager shall consult with the Adviser or Trustees at
such times as the Adviser or Trustees shall reasonably request with respect to
the overall investment policy of the Account, and with the instructions and
directions of the Adviser and of the Trustees, co-operate with the Adviser's (or
its designee's) personnel responsible for monitoring the Investment Fund's
compliance with and will conform to and comply with, the requirements of the
Act, the Internal Revenue Code of 1986, as amended, and all other applicable
federal and state laws and regulations including, among other things, the
preparation and filing of such reports as are, or may in the future be, required
by the Securities and Exchange Commission (the "Commission").

                                       3
<PAGE>

                  4. Standard of Care

                  A. The Manager shall invest the assets of the Account in the
manner provided herein and shall have no duty or responsibility with respect to
the diversification of the assets of the Trust, except with respect to the
diversification of the assets of the Account as contemplated by the Prospectus.

                  B. Except as provided in ERISA, the Manager will be under no
liability or obligation to anyone with respect to any failure on the part of the
Trust or any other investment manager to perform any of their obligations under
any agreement affecting the Account or under the terms of this Agreement or for
any error or omission whatsoever on the part of the Trust, the Adviser, or any
other investment manager.

                  C. The Manager shall not be liable for the making, retention
or sale of any investment or reinvestment made by it as herein provided, nor for
any loss to or diminution of the value of the property of the Account; provided,
however, that the Manager has acted in the premises with the care, skill,
prudence, and diligence under the circumstances then prevailing that a prudent
man acting in like capacity and familiar with such matters would use in the
conduct of any enterprise of a like character and with like aims and in
accordance with such other requirements of ERISA as applicable generally to
fiduciaries under ERISA; provided, further, however, that nothing in this
Agreement shall protect the Manager against any liability to the Adviser, the
Trust or Unitholders to which the Manager would otherwise be subject by reason
of willful misfeasance, bad faith or negligence in the performance of its duties
hereunder or by reason of its reckless disregard of its obligations and duties
hereunder. Nothing herein shall be construed to waive any liability that the
Manager has under federal or state securities laws or any other applicable laws
which cannot be waived.

                  D. The Manager may not consult with any other manager or
sub-adviser of the Investment Fund, including any other manager or sub-adviser
that is a principal underwriter or an affiliated person of a principal
underwriter, concerning transactions of the Investment Fund in securities or
other assets. Notwithstanding the terms of this paragraph 4.D., the Manager may
consult at all times with the Adviser engaged by the Trust.

                  5. General Provisions

                  A. Compensation for the services of the Manager will be as set
forth in Schedule A hereto.

                  B. With respect to securities in the Account, the Manager
shall purchase such securities from or through and sell such securities to or
through such persons, brokers or dealers as the Manager shall deem appropriate
to carry out the policy with respect to brokerage as set forth in the Prospectus
or as the Manager may direct from time to time. In providing the Account with
investment supervision, it is recognized that the Manager will give primary
consideration to securing the most favorable price and efficient execution. The
Manager shall have discretion to effect investment transactions for the
Investment Fund through broker-dealers (including, to the

                                       4
<PAGE>

extent legally permissible, broker-dealers affiliated with the Manager)
qualified to obtain best execution of such transactions who provide brokerage
and/or research services, as such services are defined in Section 28(e) of the
Exchange Act of 1934, as amended (the "Exchange Act"). The Manager shall not be
responsible for any acts or omissions by any such broker or brokers, or any
third party not owned by the Manager, provided that the Manager is not negligent
in the selection of such broker or brokers, or third parties. The Manager is
hereby authorized to combine orders on behalf of the Account with orders on
behalf of other clients of the Manager. It is understood that it is desirable
for the Trust that the Manager have access to supplemental research and security
and economic analysis and statistical services and information with respect to
the availability of securities or purchasers or sellers of securities provided
by brokers and of use to the Trust although such access may require the
allocation of brokerage business to brokers who execute transactions at a higher
cost to the Trust than other brokers who provide only execution of portfolio
transactions. Therefore, the Manager is authorized to place orders for the
purchase and sale of securities with such brokers, subject to review by the
Trust from time to time with respect to the extent and continuation of this
practice. It is understood that the services provided by such brokers may be
useful to the Manager in connection with its services to other clients.

                  C. This Agreement shall automatically terminate in the event
of its "assignment" (as that term is defined in the Act) or upon termination of
the Investment Management Agreement between the Trust and the Adviser. The
Manager agrees that it will promptly notify the Trust and the Adviser of the
occurrence or anticipated occurrence of any event that would result in the
assignment of this Agreement, including, but not limited to, a change or
anticipated change in control (as defined in the Act) of the Manager; provided
that the Manager need not provide notice of such an anticipated event before the
anticipated event is a matter of public record.

                  D. This Agreement may be terminated, without the payment of
any penalty, by either party hereto on not more than sixty (60) days' nor less
than thirty (30) days' written notice delivered or mailed by registered mail,
postage prepaid, to the other party; any such termination on behalf of the Trust
to be pursuant to a vote of the Trustees or by a vote of a majority of the
outstanding voting securities (as defined in the Act) of the Investment Fund.

                  E. The Manager shall maintain all books and records with
respect to the Investment Fund's portfolio transactions effected by it as
required by subparagraphs (b)(5), (6), (7), (9), (10) and (11) and paragraph (f)
of Rule 31a-1 under the Act, and shall furnish to the Investment Fund's Board of
Trustees such periodic and special reports as the Trustees may reasonably
request. The Manager shall make reasonably available its employees and officers
for consultation with the Trustees or officers or employees of the Adviser with
respect to any matter discussed herein, including, without limitation, the
valuation of the Investment Fund's securities.

                  F. The Manager or an affiliate shall provide the Investment
Fund's custodian on each business day with information relating to all
transactions concerning the portion of the Investment Fund's assets it manages,
and shall provide the Adviser with such information upon request of the Adviser.

                  G. The Manager shall keep the Investment Fund's books and
records required to be maintained by the Manager pursuant to this Agreement and
shall timely furnish to the Adviser all information relating to the Manager's
services hereunder needed by the Adviser to

                                       5
<PAGE>

keep the other books and records of the Investment Fund required by Rule 31a-1
under the Act or any successor regulation. The Manager agrees that all records
which it maintains for the Investment Fund are the property of the Investment
Fund, and the Manager will surrender promptly to the Investment Fund any of such
records upon the Investment Fund's request; provided, however, that the Manager
may retain a copy of such records. The Manager further agrees to preserve for
the periods prescribed by Rule 31a-2 of the Commission under the Act or any
successor regulation any such records as are required to be maintained by it
pursuant to this Agreement.

                  H. The Manager may rely on the authenticity, truth and
accuracy of, and will be fully protected in acting upon:

                  (a)   Any notice, direction, certification, approval or
                        other writing of the Adviser, if evidenced by an
                        instrument signed by the President, a Vice President,
                        the Treasurer or the Assistant Treasurer of the
                        Adviser;

                  (b)   Any copy of a resolution of the Trustees, if
                        certified by the Secretary of the Trust;

                  (c)   Any notification or information provided by the
                        custodian of the assets in the Account, if evidenced
                        by an instrument signed by an officer of the
                        custodian; or

                  (d)   Any oral notice or instruction reasonably believed to
                        be genuine and to be given by the Adviser or the
                        Trustees or its authorized delegate or by the
                        custodian or any other investment manager.

                  I. The Manager may rely on, and will be fully protected with
respect to any action taken or omitted in reliance on, any information,
statement or certificate delivered to the Manager by the Adviser or Trustees
with respect to any matter concerning the Trust and the operation and
administration of the Account. The Manager is expressly authorized to consult
with the Adviser with respect to any matters arising in the administration of
the Account and to act on the advice of the Adviser, provided nothing herein
shall limit the full responsibility of the Manager for the management of the
assets of the Account as provided herein.

                  J. Communications from the Manager to the Trust shall be

                  K. Unless the Adviser instructs the Manager otherwise in

                        RETIREMENT SYSTEM INVESTORS INC.
                        INVESTMENT SUB-ADVISORY AGREEMENT

Name of Manager:     RCM CAPITAL MANAGEMENT LLC

Address:             Four Embarcadero Center, Suite 3000
                     San Francisco, CA  94111-4189

Attention:           Mr. Steven Wong

Investment Fund:     Core Equity Fund

Compensation Terms:

Terms used herein shall have the meaning used in the Investment Management
Agreement between the Adviser and the Manager ("Agreement"). The Adviser agrees
to pay to the Manager, as full compensation and reimbursement for the services
to be rendered pursuant to the Agreement and any expenses incurred in connection
therewith, a fee at the end of each fiscal quarter of the Trust, computed by
applying the following rate to the Account:

               Effective October 1, 2004, 0.40% of the first $100
               million of assets, 0.25% of the next $300 million of
               assets, 0.20% of the next $600 million of assets and
               0.15% of assets over $1 billion.

Billing is done for each quarter on the basis of services performed during that
particular quarter. The quarterly fee is calculated on the basis of the average
of the asset value as of the last day of each month of each calendar quarter,
equal to one-fourth of the annual rate.

If the Agreement commences on a date other than on the beginning of any such
quarterly period, or terminates on a date other than the end of any such
quarterly period, the fee payable hereunder shall be proportionately reduced
according to the number of days during such period services were rendered by the
Manager.
