ABOUT THE PROPOSALS

The purpose of this proxy is to seek shareholder approval of the following
proposals:

- -  TO ELECT TRUSTEES - Shareholders of all the Funds are being asked to elect
   three new Trustees.

- -  TO CONSIDER CHANGES TO THE CURRENT ADVISORY ARRANGEMENTS FOR EACH FUND -
   Shareholders of each Fund other than the AXA Rosenberg Enhanced 500 Fund
   (the "AXA 500 Fund") are being asked to approve a Management Agreement with
   Charles Schwab Investment Management, Inc. ("CSIM"), pursuant to which CSIM
   would provide overall investment management for such Fund. Shareholders of
   each of those Funds are also being asked to approve a Subadviser Agreement
   among the Trust, CSIM and AXA Rosenberg Investment Management LLC ("AXA
   Rosenberg"), which currently serves as investment adviser to each Fund. As
   subadviser, AXA Rosenberg would continue to provide day-to-day portfolio
   management services to the Funds. Shareholders of the AXA 500 Fund are
   [contemporaneously] receiving an Information Statement describing revisions
   to that Fund's objective, investment strategy and investment advisory
   arrangements generally. For the Funds being asked to vote on Proposals 2 and
   3 (the "Voting Funds"), the amount that shareholders pay for investment
   advisory services will not increase, and may be reduced.

The Trustees believe that the proposals are in the best interests of
shareholders, but shareholder approval is required to make them happen. This
document tells you more about the proposals and explains the main reasons that
the Trustees believe the proposals are in the best interests of shareholders.

Please take a moment to understand the proposed changes and vote your shares.

INTRODUCTION

PURPOSE OF THIS DOCUMENT

This proxy statement is being furnished to shareholders of each Fund in
connection with the solicitation of proxies by and on behalf of the Board of
Trustees of the Trust (the "Board of Trustees") for use at the Trust's Special
Meeting of shareholders to be held at the offices of Charles Schwab & Co., 101
Montgomery Street, San Francisco, California on [January 28, 2004], at [INSERT
TIME OF MEETING], and at any adjournment thereof (the "Meeting"). This proxy
statement is first being mailed to shareholders on or about [INSERT MAILING
DATE].

WHO MAY VOTE

The Board of Trustees has fixed the Record Date as the close of business on
[November 24, 2003]. Only holders of shares of the Funds at the close of
business on the Record Date are entitled to notice of, and to vote at, the
Meeting. The chart on page 9 shows the number of issued and outstanding shares
of each Fund entitled to vote.

The holder of each full share of a Fund outstanding as of the close of business
on the Record Date is entitled to one vote upon each matter properly submitted
to the Meeting that relates to that Fund, and a proportionate fractional vote
for any fractional shares held.

HOW TO VOTE

Shareholders may vote by Internet, phone or by returning the enclosed proxy
card. Depending on the number of Funds of which you are a shareholder and the
number of accounts you have, you may receive more than one proxy card.

If you vote by mail, complete, date, sign and promptly return the enclosed proxy
card(s) in the accompanying envelope. If you properly execute and return your
proxy card(s) prior to the meeting, your shares will be voted in accordance with
the instructions marked on the proxy card(s). If no instructions are marked on
the proxy card(s), then your shares will be voted FOR the proposals described in
this proxy statement and in the discretion of the persons named as proxies in
connection with any other matter that may properly come before the Meeting.

You may revoke your proxy at any time prior to its exercise by voting in person
at the meeting or by submitting, before the Meeting, written notice of
revocation or a later-dated proxy.

QUORUM AND VOTING REQUIREMENTS

In order to take action on any proposal, a "quorum" of forty percent (40%) of
shares entitled to vote on that proposal, must be present in person or by proxy.

                                        6
<Page>

To be elected as a Trustee, each individual nominated for election to the
Board of Trustees (each a "Nominee") must receive the affirmative vote of the
holders of a plurality of the outstanding shares of all of the Funds voting
together as a single class. This means that the three Nominees for election
receiving the highest number of affirmative votes cast at a meeting will be
elected, as long as the votes FOR such Nominee exceed the votes AGAINST such
Nominee. As required by the Investment Company Act of 1940, as amended (the
"1940 Act"), approval of Proposals 2 and 3 requires the affirmative vote of a
majority of the outstanding voting securities of the Fund entitled to vote on
such Proposal. As defined by the 1940 Act, a "majority of the outstanding
voting securities" means the vote of (i) 67% or more of the Fund's
outstanding shares present at a meeting, if the holders of more than 50% of
the outstanding shares of the Fund are present or represented by proxy, or
(ii) more than 50% of the Fund's outstanding shares, whichever is less.

OTHER VOTING-RELATED MATTERS

If a quorum is not present at the meeting, or if sufficient votes to approve
a proposal are not received, the persons named as proxies may propose one or
more adjournments of the Meeting to permit further solicitation of proxies.
Any adjournment(s) of the Meeting will require the affirmative vote of a
majority of those shares of the relevant Funds present at the meeting in
person or by proxy and entitled to vote on the proposal. If the Meeting is
adjourned with respect to a proposal, any other proposal may still be acted
on by shareholders so long as there is a quorum.

The Board of Trustees does not presently know of any matter to be considered at
the meeting other than the matters described in the Notice of Special Meeting
accompanying this proxy statement. If any other matter should arise, however,
the persons named in properly authorized proxies have discretionary authority to
vote such proxies as they decide.

Abstentions and broker "non-votes" (i.e., proxies received from brokers or
nominees indicating that they have not received instructions from the beneficial
owner or other person entitled to vote shares) will be counted as shares that
are present for purposes of determining the presence of a quorum, but will not
be counted as votes FOR a proposal. Accordingly, abstentions and broker
non-votes will have the effect of a vote AGAINST Proposals 2 and 3.

SOLICITATION OF PROXIES

The Trust has retained King Mutual Fund Services, a proxy solicitation firm at
an estimated cost of [$XXXX]. CSIM and AXA Rosenberg will bear the expenses
incurred in connection with preparing this proxy statement, including certain
legal costs. CSIM will bear the cost of retaining the proxy solicitation firm
and all other costs associated with the solicitation of proxies, including the
reimbursement of certain parties for their expenses in forwarding proxy
materials to beneficial owners of Fund shares.

                                        7

In addition to the solicitation of proxies by mail, officers of the Trust and
officers and employees of CSIM and AXA Rosenberg also may solicit proxies
electronically, by telephone, fax, in person or by other means.

Proposals 2 and 3 are contingent on each other with respect to each Fund, so
if shareholders of a Fund do not approve both proposals, the Board of
Trustees of the Trust (the "Board or "Board of Trustees") does not intend to
implement either proposal with respect to that Fund. Proposal 1 regarding the
election of new Trustees will not be implemented unless Proposals 2 and 3 are
approved and implemented by at least one of the Voting Funds. If shareholders
approve Proposals 2 and 3 with respect to some, but not all, Voting Funds,
the current Trustees may determine to maintain the STATUS QUO by not
implementing any of the proposals with respect to any of the Funds.

ABOUT THE PROPOSALS

The Board of Trustees has proposed changes to the management structure of the
Voting Funds. These changes are intended to enhance the management and
distribution services provided to these Funds.

ELECTION OF TRUSTEES - The Board of Trustees is responsible for overseeing
the activities of the Funds and their service providers. Currently, the Board
consists of four trustees, one of whom is an interested person (as defined in
Section 2(a)(19) of the 1940 Act) of the Trust (an "Interested Trustee") and
three of whom are not interested persons of the Trust (each an "Independent
Trustee"). It is proposed that shareholders elect three new trustees to the
Board. Two of the Nominees would be Independent Trustees (even after
implementation of the proposals) and the other is an officer of Charles
Schwab & Co., Inc. ("Schwab"), an affiliate of CSIM. The new Nominees for
Independent Trustee have had wide ranges of experience, including serving as
trustees of other mutual funds advised by CSIM, and will apply this
experience in overseeing the Funds. It is anticipated that if shareholders
approve the proposed changes to the investment advisory arrangements for the
Funds, the current Interested Trustee and two of the three current
Independent Trustees will resign from the Board of Trustees, leaving the
Board with three new Trustees, but maintaining the current composition of
three Independent Trustees and one Interested Trustee.

APPROVAL OF MANAGEMENT AGREEMENT AND SUBADVISER AGREEMENT - AXA Rosenberg
currently serves as investment adviser to each Fund. As investment adviser,
AXA Rosenberg directs the investments of the Funds and is responsible for
overseeing regulatory compliance, overseeing the Trust's other service
providers and generally monitoring the affairs of and providing an investment
program for the Funds, subject to the supervision of the Trustees. If
shareholders of the Voting Funds approve the proposed changes to the advisory
arrangements, AXA Rosenberg, subject to the supervision of CSIM, would
continue to provide day-to-day portfolio management services to the Funds as
investment sub-adviser. However, CSIM would be the investment adviser to the
Funds. As investment adviser, CSIM would take over AXA Rosenberg's
non-portfolio management related functions, such as monitoring Fund
compliance and supervising services provided to the Funds and shareholders.
If CSIM is approved as investment adviser, it is anticipated that the Board may
in the future appoint CSIM's affiliate, Charles Schwab & Co., Inc. ("Schwab"),
as principal underwriter or distributor of the Funds. It is also expected that,
upon approval of the new advisory arrangements described above, the business of
the Funds would be conducted under the name "Laudus Rosenberg Funds."

The Trustees believe that engaging CSIM to serve as investment adviser and
Schwab as distributor will allow AXA Rosenberg to focus exclusively on the
area of its greatest expertise - making investment decisions for the Funds.
It will also allow the Funds to benefit from CSIM's experience providing
mutual fund management. CSIM currently oversees the investment programs for
49 mutual funds with more than $140.8 billion in assets. In managing these
funds, CSIM has developed significant regulatory compliance resources and
systems for providing services to fund shareholders. CSIM also manages other
funds for which investment sub-advisers provide day-to-day portfolio
management.

                                       10
<Page>

Moreover, it is expected that approving this proposal may result in
operational efficiencies and a larger, long-term shareholder base. This may
result in expenses being spread over a larger pool of assets and potentially
lower operating expenses and/or transaction costs to the Funds (as a
percentage of assets).

In connection with the proposals, AXA Rosenberg and CSIM have entered into an
agreement regarding AXA Rosenberg's and CSIM's cooperation in realigning
responsibilities for the Funds' assets. The Agreement commits CSIM to using
commercially reasonable efforts (including, in some instances, reduction of
CSIM's management fee) to maintain the proposed sub-advisory fees for AXA
Rosenberg and, subject to certain conditions, provides that CSIM will pay
compensation to AXA Rosenberg in the event that AXA Rosenberg is terminated
as investment sub-adviser for a Fund. Consequently, CSIM will have a material
economic interest in avoiding the termination of AXA Rosenberg or reducing
AXA Rosenberg's sub-advisory fee. The amount of compensation owed to AXA
Rosenberg upon its termination, if any, is based on a formula that takes into
account when AXA Rosenberg is terminated, the circumstances surrounding the
termination, the performance of the Fund(s) at the time of termination, the
assets under management at the time of termination and the amount of
compensation under the Sub-Advisory Agreement that AXA Rosenberg received in
the 12-month period prior to the termination. The agreement also contains a
limited non-compete provision that provides that, for an eight year period
(or a shorter period in certain events), AXA Rosenberg cannot advise other
mutual funds, subject to certain exceptions, and that CSIM, subject to
certain exceptions, cannot offer other "quantitatively managed" mutual funds
except under its existing Schwab MarketMasters, Schwab and Excelsior brands.
Consummation of the agreement is conditioned upon, among other things,
approval of the proposals by shareholders of each Fund. Each of Dr. Kenneth
Reid, a current trustee of the Trust, and Jeffrey Lyons, a Nominee, may be
deemed to have a material interest in all of the Proposals because of the
agreement described in this paragraph by virtue of his employment with and
direct or indirect ownership interest in AXA Rosenberg and CSIM's corporate
parent, respectively.

If the shareholders do not approve the proposals, the Trustees will consider
other possible courses of action which may be in the best interest of
shareholders.

PROPOSAL 1

TO ELECT TRUSTEES.

ELECTION OF TRUSTEES

It is proposed that shareholders of the Trust elect three Nominees to serve as
Trustees, each to hold office until a successor is elected and qualified. The
three Nominees (who have not previously served on the Board of Trustees) include
two Independent Nominees and one officer of Schwab, all of whom serve on the
boards of trustees of other mutual funds advised by CSIM.

The persons named in the accompanying proxies intend to vote for the election of
the persons listed below unless shareholders indicate on their proxy cards their
desire to withhold authority to vote for election to office.

Each Nominee has consented to being named in this proxy statement and has agreed
to serve as a Trustee if elected, provided that the other proposals are also
approved and implemented (or the current Trustees proceed to effect the new
advisory arrangement with respect to some but not all of the Funds). If the new
Trustees are elected and the other proposals are implemented, it is anticipated
that Dr. Reid, the current Interested Trustee, and two of the three current
Independent Trustees (William F. Sharpe and Dwight M. Jaffee) will resign
from the Board.

The two Nominees to serve as Independent Trustees have been nominated by Messrs.
Sharpe and Jaffee and Nils H. Hakansson, the current Independent Trustees.
Messrs. Sharpe, Jaffee and Hakansson are familiar with the background and
relevant experience of those two Nominees and have met with them in person to
discuss the nomination and their service as Independent Trustees.

The Board of Trustees does not know of any reason why any Nominee would be
unable or unwilling to serve as a trustee, but if any Nominee should become
unable to serve prior to the meeting, the proxy holders reserve the right to
vote for another person of their choice as Nominee or Nominees.

TRUSTEE ACTIVITIES AND COMPENSATION

MEETINGS AND COMMITTEES - During the Trust's most recent fiscal year, the Board
of Trustees met four times. Each Trustee attended all of those meetings.

The Trust has a standing Audit Committee, which is composed of all of the
current Independent Trustees. The Audit Committee assists the Trustees in their
oversight of the Trust's financial reporting process and met once during the
Trust's most recently completed fiscal year. Each member of the Audit Committee
attended that meeting.

The Trust does not have a standing nominating committee or a standing
compensation committee or any committee performing similar functions. Consistent
with the requirements of certain other exemptive rules under the 1940 Act, the
selection and nomination of Independent Trustees is committed to the other
Independent Trustees.

PROPOSAL 2

TO APPROVE CSIM AS INVESTMENT ADVISER FOR EACH VOTING FUND BY APPROVING A
MANAGEMENT AGREEMENT BETWEEN CSIM AND THE TRUST ON BEHALF OF EACH VOTING FUND.

BACKGROUND

AXA Rosenberg currently serves as investment adviser to each Fund pursuant to
a separate advisory agreement with the Trust on behalf of each Fund. At a
meeting of the Board of Trustees held on November 3, 2003, the Board, and the
Independent Trustees voting separately, unanimously approved the appointment
of CSIM as investment adviser to each Fund and approved a Management
Agreement (each a "Proposed Management Agreement") between the Trust, on
behalf of each Fund, and CSIM. The Board also recommended that each Proposed
Management Agreement be submitted to shareholders of each respective Fund for
approval.

There is no intention to change the investment mandate of any of the Voting
Funds upon approval of CSIM as investment manager.

As described more fully under "Proposal 3," below, the Board is also proposing
that AXA Rosenberg, subject to CSIM's supervision, continue to provide
day-to-day portfolio management of each Fund.

SUMMARY OF THE PROPOSED ADVISORY AGREEMENT

A summary of the Proposed Management Agreements and information about CSIM
are provided below. A form of the Proposed Management Agreement is attached
as Exhibit A to this proxy statement, and the following description of the
Proposed Management Agreement is qualified in its entirety by reference to
such Exhibit.

The Proposed Management Agreements contain certain provisions that are
different from the provisions of the current advisory agreements with AXA
Rosenberg. A number of the provisions, however, including provisions relating
to the standards of care and limitation of liability, the selection of
portfolio securities and duration and termination, will not be materially
different under the Proposed Management Agreement.

DUTIES UNDER THE PROPOSED MANAGEMENT AGREEMENT - Under each Proposed
Management Agreement, CSIM will, subject to the direction and control of the
Board of Trustees and at its expense, have responsibility (either directly or
in a supervisory capacity) for (i) furnishing continuously an investment
program for the particular Fund, making investment decisions on behalf of
such Fund and placing all orders for the purchase and sale of its portfolio
securities, and (ii) furnishing all necessary office space and equipment,
providing bookkeeping and clerical services required to perform its duties
thereunder and paying all salaries, fees and expenses of the Trustees and
officers of the Trust who are affiliated persons of CSIM. The Agreement also
provides that CSIM may, subject to the provisions of the Trust's Second

                                       17
<Page>

Amended and Restated Agreement and Declaration of Trust, as amended, and the
1940 Act, delegate its responsibility for day-to-day portfolio management and
trade execution to an investment sub-adviser. Each Proposed Management
Agreement provides that CSIM is responsible for payment of all compensation
to any such investment sub-adviser. The provisions regarding duties of the
adviser under the Proposed Management Agreement are similar to those of the
the current investment advisory agreements except that the current investment
advisory agreements do not provide for the delegation of responsibilities to
an investment sub-adviser.

STANDARD OF CARE - Each Proposed Management Agreement provides that in the
absence of willful malfeasance, bad faith or gross negligence on the part of
CSIM, or reckless disregard of its obligations and duties thereunder, CSIM
shall not be subject to any liability to the Trust, to any Fund or to any
shareholder, officer, director or Trustee thereof, for any act or omission in
the course of, or connected with, rendering services under each Proposed
Management Agreement. The limitation of liability provisions of each Proposed
Management Agreement are substantially similar to those of the current
investment advisory agreements.

     PORTFOLIO TRANSACTIONS - For so long as it is sub-adviser, AXA Rosenberg
will have exclusive responsibility for effecting portfolio transactions,
including the selection of brokers in connection therewith, subject only to
general oversight by CSIM. However, the provisions relating to execution of
portfolio transactions in each Proposed Management Agreement authorize CSIM
to select brokers and dealers to execute portfolio transactions, subject to
its overall obligation to seek the most favorable price and execution
available for the Funds. In selecting a broker or dealer, CSIM shall consider
all factors it deems relevant, including, by way of illustration, the price,
the size of the transaction, the nature of the market for the security, the
amount of the commission, the timing of the transaction taking into account
market prices and trends, the reputation, experience and financial stability
of the broker involved, and the quality of service rendered by the broker in
other transactions. Subject to such policies as the Trustees may determine,
CSIM shall not be deemed to have acted unlawfully or to have breached any
duty created by each Proposed Management Agreement or otherwise solely by
reason of its having caused the Trust to pay, on behalf of a particular Fund,
a broker that provides brokerage and research services to CSIM or any
affiliated person of CSIM an amount of commission for effecting a portfolio
investment transaction in excess of the amount of commission another broker
would have charged for effecting that transaction, if CSIM determines in good
faith that such amount of commission was reasonable in relation to the value
of the brokerage and research services provided by such broker, viewed in
terms of either that particular transaction or CSIM's overall
responsibilities with respect to such Fund and to other clients of CSIM and
any affiliated person of CSIM as to which CSIM or any affiliated person of
CSIM exercises investment discretion. The portfolio transactions provisions
of each Proposed Management Agreement are substantially similar to those of
the current investment advisory agreements. It is expected that AXA
Rosenberg's policy with respect to the selection of brokers and the use of
"soft dollars" will continue under the Proposed Management and Sub-Adviser
Agreements.

                                       18

     DURATION AND TERMINATION - Each Proposed Management Agreement shall be
in effect until two years from its execution date and thereafter shall be
continued for successive annual periods, provided that such continuance is
specifically approved at least annually (a) by the affirmative vote of a
majority of the outstanding shares of a particular Fund or by the Board of
Trustees, and (b) by the vote of a majority of the Trustees who are not
parties to such Proposed Management Agreement or "interested persons" (as
defined in the 1940 Act) of any such party, cast in person at a meeting
called for the purpose of voting on such approval. If the continuance of a
Proposed Management Agreement is submitted to the shareholders of a
particular Fund for their approval and such shareholders fail to approve such
continuance of such Proposed Management Agreement as provided therein, CSIM
may continue to serve thereunder in a manner consistent with the 1940 Act and
the rules and regulations thereunder. Each Proposed Management Agreement may
be terminated at any time by the vote of a majority of the Fund's outstanding
voting securities or by a vote of the entire Board of Trustees on sixty days'
written notice to CSIM or by CSIM on sixty days' written notice to the Trust.
Each Proposed Management Agreement shall terminate automatically in the event
of its "assignment" (as defined in Section 2(a)(4) of the 1940 Act). Each
Proposed Management Agreement may not be materially amended unless such
amendment is approved by the affirmative vote of a majority of the
outstanding shares of the particular Fund, and by the vote of a majority of
the Trustees who are not interested persons (as defined in the 1940 Act) of
the Trust or of CSIM, cast in person at a meeting called for the purpose of
voting on such amendment. The duration and termination provisions of each
Proposed Management Agreement are substantially similar to those of the
current investment advisory agreements.

COMPENSATION - Each Voting Fund's advisory fee under its Proposed Management
Agreement will be the same or lower than the advisory fees paid by such Fund
under its current advisory agreement.

The following table compares the fees payable to AXA Rosenberg under the
current advisory agreements with the fees payable to CSIM under the Proposed
Management Agreements. It also shows how much was AXA Rosenberg earned under
each advisory agreement, and how much would have been payable to CSIM under
the corresponding Proposed Management Agreement if it had been in effect, for
the fiscal year ended March 31, 2003.

EXPENSE LIMITATIONS

The fees in the table above reflect the fees payable by each Fund to AXA
Rosenberg and CSIM under the current advisory agreement and the Proposed
Management Agreement, respectively. Currently, AXA Rosenberg waives fees
and/or reimburses the Funds as necessary to keep ordinary operating expenses
incurred by a Fund in any fiscal year, including but not limited to
investment advisory fees (but subject to certain exclusions as described
below), from exceeding the limits set forth in the table below through March
31, 2004. CSIM has agreed to extend the limitations through March 31, 2007.
Both the current and proposed expense limitation agreements exclude
non-recurring account fees, extraordinary expenses, dividends on securities
sold short, service fees, subtransfer agency and subaccounting

                                       20

fees and distribution and shareholder service fees, so total Fund operating
expenses will be higher than the amounts shown below. The table below also
reflects the total annual operating expenses of each Fund net of expense
limitations under the current AXA Rosenberg expense limit and the proposed CSIM
expense limit, based on asset levels and other expenses for the Funds' last
fiscal year.

  under Form N-1A of the 1940 Act), total expenses are based on estimated
  amounts.

A note on redemption fees: In addition to on-going operating expenses as set
forth above, the Trust expects to continue its policy of imposing redemption
fees on share exchanges or redemptions that occur within one month of
purchase. The Trustees believe that redemption fees have the equitable result
of requiring redeeming shareholders to bear brokerage and other transaction
costs associated with their redemptions, rather than having those costs borne
by non-redeeming shareholders. In particular, this policy has the beneficial
effect of discouraging market timers and other short-term investors whose
activities might otherwise adversely affect the Funds and their other
shareholders.

TRUSTEES' CONSIDERATIONS

The Trustees, including the Independent Trustees, approved each Proposed
Management Agreement at a meeting held on November 3, 2003. The Trustees also
held meetings on September 10 and October 15, 2003, to consider each Proposed
Management Agreement and ask questions of representatives of CSIM. The
Independent Trustees also held separate meetings in person or by telephone on
August 6, August 29, September 10, September 16, September 24 and October 15,
2003 to discuss each Proposed Management Agreement and other information
provided by AXA Rosenberg or CSIM pursuant to their requests. The Trustees
received written and oral information from CSIM regarding CSIM's key
personnel and its experience in managing mutual funds. The Trustees reviewed
CSIM's qualifications to act as investment adviser to the Funds. In
recommending that shareholders approve each Proposed Management Agreement,
the Trustees carefully evaluated the experience of CSIM's key personnel in
institutional investing and the quality of services CSIM is expected to
provide to each Fund, including, but not limited to: (1) the fee and expense
ratios of comparable mutual funds; (2) the nature and quality of services
expected to be rendered to each Fund by CSIM; (3) the benefits that might
accrue to the Funds, including increased efficiencies and economies of scale,
as a result of the size and depth of CSIM's and its affiliates' mutual fund
organizations; (4) the distinct investment objectives and policies of each
Fund; (5) the history, reputation, qualification and background of CSIM, as
well as the qualifications of its personnel and its financial condition; (6)
its performance record;

                                       22
<Page>

(7) CSIM's compliance infrastructure, including systems and procedures designed
to comply with recent federal regulations affecting mutual funds; (8) CSIM and
it's affiliates' ability to support the growth of assets invested in the Funds;
(9) CSIM's experience overseeing, monitoring and supervising the services of
sub-advisers to certain funds for which it currently serves as investment
adviser; and (10) other factors deemed relevant. The Trustees also reviewed the
fees to be paid to CSIM by each Fund under each Proposed Management Agreement in
comparison to those being charged in the relevant segment of the mutual fund
business.

Based on this evaluation, the Trustees considered whether each Proposed
Management Agreement was in the best interests of each Fund and the Fund's
shareholders. One of the issues influencing the Trustees' decision was the
fact that despite the change in investment advisor, the investment objective
of each Voting Fund will remain the same, and the investment strategies,
policies, restrictions, and current policy with respect to redemption fees of
each Voting Fund will remain substantially the same. The Trustees considered
that it is expected that the Voting Funds' shares will be subject to the same
or a lower operating expense ratio as a result of the change in advisory
arrangements. They also considered the potential for a larger long-term
shareholder base as a result of CSIM's involvement, which would result in
certain expenses being spread over a larger pool of assets and potentially
lower transaction costs to the Funds. They discussed the various challenges
to the Funds' maintaining or increasing their assets over the long term and
how the proposed relationship with CSIM could address those challenges.
Furthermore, after adoption of each Proposed Management Agreement, AXA
Rosenberg will continue to manage the assets of each Fund as sub-adviser to
the Funds. Accordingly, for the reasons noted above, together with other
factors and information considered relevant, and recognizing that there can
be no assurance that any of the potential benefits described above will be
realized, the Trustees concluded that each Proposed Management Agreement
would be in the best interest of each Fund and the Fund's shareholders.

PROPOSAL 3

TO APPROVE AXA ROSENBERG AS AN INVESTMENT SUB-ADVISER FOR EACH FUND BY APPROVING
A SUBADVISER AGREEMENT AMONG CSIM, AXA ROSENBERG AND THE TRUST ON BEHALF OF
EACH FUND.

BACKGROUND

At a meeting of the Board of Trustees held on November 3, 2003, the Board,
including the Independent Trustees voting separately, unanimously approved
the proposed Subadviser Agreement among CSIM, AXA Rosenberg and the Trust on
behalf of each Fund (each a "Proposed Subadviser Agreement"). The Board also
recommended that each Proposed Subadviser Agreement be submitted to
shareholders of each Fund for approval.

SUMMARY OF THE PROPOSED SUBADVISER AGREEMENT

A summary of the Proposed Subadviser Agreements and information about AXA
Rosenberg are provided below. A form of the Proposed Subadviser Agreement is
attached as Exhibit B to this proxy statement, and the following description of
the Proposed Subadviser Agreement is qualified in its entirety by reference to
such Exhibit.

DUTIES UNDER THE PROPOSED SUBADVISER AGREEMENT - Under each Proposed Subadviser
Agreement, AXA Rosenberg, at its expense, will furnish continuously an
investment program for the particular Fund and will make investment decisions on
behalf of such Fund and place all orders for the purchase and sale of portfolio
securities and all other investments, subject to the supervision of CSIM and the
Trustees. Under each Proposed Subadviser Agreement, CSIM and the Trust have
agreed that CSIM shall have no authority for the selection of brokers and/or the
day-to-day placing of orders in connection with the particular Fund, subject
only to CSIM's general supervisory obligations.

STANDARD OF CARE - Each Proposed Subadviser Agreement provides that, in the
absence of willful misfeasance, bad faith or gross negligence on the part of AXA
Rosenberg, or reckless disregard of its obligations and duties thereunder, AXA
Rosenberg shall not be subject to any liability to CSIM, to the Trust, to any
Fund, or to any shareholder, officer, director or Trustee thereof, for any act
or omission in the course of, or connected with, rendering services under each
Proposed Subadviser Agreement. This standard of care is substantially similar to
the standard of care to which AXA Rosenberg is currently held under the existing
management contracts.

PORTFOLIO TRANSACTIONS - Each Proposed Subadviser Agreement authorizes AXA
Rosenberg to select brokers and dealers to execute portfolio transactions,
subject to the brokerage policies established by the Trustees and AXA
Rosenberg's overall obligation to seek the most favorable price and execution
for the particular Fund. In selecting a broker or dealer, AXA Rosenberg shall
consider all factors it deems relevant, including, by way of illustration,
price, the size of the transaction, the nature of the market security, the
amount of the commission, the timing of the transaction taking into account

and trends, the reputation, experience and financial ability of the broker
involved, and the quality of service rendered by the broker in other
transactions. Subject to such policies as the Trustees may determine and
communicate to AXA Rosenberg in writing, AXA Rosenberg shall not be deemed to
have acted unlawfully or to have breached any duty created by any Proposed
Subadviser Agreement or otherwise solely by reason of its having caused a
Fund to pay a broker that provides brokerage and research services to AXA
Rosenberg or any affiliated person of AXA Rosenberg an amount of commission
for effecting a portfolio investment transaction in excess of the amount of
commission another broker would have charged for effecting that transaction,
if AXA Rosenberg determines in good faith that such amount of commission was
reasonable in relation to the value of the brokerage and research services
provided by such broker, viewed in terms of either that particular
transaction or AXA Rosenberg's overall responsibilities with respect to the
particular Fund and to other clients of AXA Rosenberg and any affiliated
person of AXA Rosenberg as to which AXA Rosenberg or any affiliated person of
AXA Rosenberg exercises investment discretion. The portfolio transaction
provisions of each Proposed Subadviser Agreement are substantially similar to
those of the current investment advisory agreements. It is expected that AXA
Rosenberg's policy with respect to the selection of brokers and the use of
"soft dollars" will continue under the Proposed Management and Subadviser
Agreements.

DURATION AND TERMINATION - Each Proposed Subadviser Agreement shall be in
effect until two years from its execution date and thereafter shall be
continued for successive annual periods, provided that such continuance is
specifically approved at least annually (a) by the affirmative vote of a
majority of the outstanding shares of the particular Fund or by the Board of
Trustees, and (b) by the vote of a majority of the Trustees who are not
parties to such Proposed Subadviser Agreement or "interested persons" (as
defined in the 1940 Act) of any such party, cast in person at a meeting
called for the purpose of voting on such approval. Each Proposed Subadviser
Agreement may be terminated at any time by the vote of a majority of the
particular Fund's outstanding voting securities or by a vote of the entire
Board of Trustees on 60 days' written notice to AXA Rosenberg or by AXA
Rosenberg on 60 days' written notice to the Trust. Each Proposed Subadviser
Agreement shall terminate automatically in the event of its "assignment" (as
defined in Section 2(a)(4) of the 1940 Act). Each Proposed Subadviser
Agreement shall not be amended except by a writing executed by each of the
parties thereto. In certain circumstances, AXA Rosenberg shall be entitled to
payment by CSIM (not the Fund) in the event of AXA Rosenberg's termination
with respect to a particular Fund.

COMPENSATION - Under the Proposed Subadviser Agreement, CSIM (not the Funds)
will pay AXA Rosenberg for its services in respect of each Fund out of the fee
it receives from such Fund. The total compensation payable to AXA Rosenberg by
CSIM will be based on the Fund's average daily net assets and will be equal to
(1) a base sub-advisory fee, plus or minus (2) a performance adjustment (if
any), plus (in the case of all Funds except the AXA Rosenberg U..S. Small
Capitalization Fund) (3) an adjustment (if any) for assets under management, all
as summarized below. Such compensation is described in detail on Schedule A to
the Proposed Subadviser Agreement, which is attached as Exhibit [B] to this
Proxy Statement, and the following summary is qualified in its entirety by the
Proposed Subadviser Agreement and Schedule A thereto.

BASE SUB-ADVISORY FEE.

FUNDS OTHER THAN THE AXA ROSENBERG U.S. SMALL CAPITALIZATION FUND. The table
below reflects the base annual sub-advisory fee payable to AXA Rosenberg by CSIM
with respect to each Fund other than the AXA Rosenberg U.S. Small Capitalization
Fund. As shown in the table, the base sub-advisory fees are subject to "break
points" so that for each such Fund, AXA Rosenberg receives, quarterly in
arrears, a percentage (as shown in the table on an annualized basis) of such
Fund's First Tier Assets, a lower percentage (as shown in the table on an
annualized basis) of such Fund's Second Tier Assets, if any, and a still lower
percentage (as shown in the table on an annualized basis) of such Fund's Third
Tier Assets, if any. For purposes of the preceding sentence, "First Tier Assets"
are comprised of a Fund's average daily net assets over the relevant quarter up
to such Fund's total assets as of the date on which AXA Rosenberg becomes
Subadviser to the Fund; "Second Tier Assets" are comprised of a Fund's portion
of the aggregate average daily net assets of all Funds (except the AXA Rosenberg
U.S. Small Capitalization Fund) over such quarter between (a) 2.5 billion, and
(b) the aggregate First Tier Assets of all Funds (except the AXA Rosenberg U.S.
Small Capitalization Fund); and "Third Tier Assets" are comprised of a Fund's
portion of the aggregate average daily net assets of all Funds (except the AXA
Rosenberg U.S. Small Capitalization Fund) in excess of $2.5 billion.

- ----------------------
* The rates for any Fund set forth in the table may be adjusted if the gross
advisory fee rates payable to CSIM by such Fund are adjusted by the Trustees or
the shareholders of such Fund.

AXA ROSENBERG U.S. SMALL CAPITALIZATION FUND. The base annual sub-advisory fee
payable to AXA Rosenberg by CSIM with respect to the AXA Rosenberg U.S. Small
Capitalization Fund shall also be paid quarterly in arrears, may be adjusted if
the gross advisory payable to CSIM by the Fund is adjusted by the Trustees or
the Fund's shareholders, and shall also be subject to "break points," currently
as follows (on an annualized basis): 0.72% of the Fund's average daily net
assets up to its assets as of the date on which AXA Rosenberg becomes Subadviser
to the Fund (the "Existing Assets"); and 0.405% of the Fund's average daily net
assets in excess of the Existing Assets.

         PERFORMANCE ADJUSTMENT. The fee payable to AXA Rosenberg will be
increased or decreased by a performance component (the "Performance Adjustment")
that will vary proportionately with the difference between (a) the investment
performance of the relevant Fund over a rolling three-year period minus the
investment record of the respective index set forth in Exhibit D over the same
period, expressed as a percentage, whether the result is positive or negative,
and (b) (i) 1.0% for Group A Funds (as listed in the table below), (ii) 2.0% for
Groups B Funds (as listed in the table below), or 2.5% for Group C Funds (as
listed in the table below). To the extent that the percentage described in
clause (a) in the preceding sentence falls within a "Null Zone" that will be
equal to a particular percentage above or below zero, there will be no
Performance Adjustment to

                                       28
<Page>

the  sub-advisory  base fee. The Null Zone will be plus or minus 1.0%, plus or
minus 2.0%,  and plus or minus 2.5% for funds falling within Groups A, B, and
C, respectively. Group A, B, and C Funds are as follows:

<Table>
<Caption>
              GROUP A                              GROUP B                             GROUP C
- ------------------------------------- ----------------------------------- -----------------------------------
                                                                    
U.S. Large Capitalization Fund        U.S. Small Capitalization Fund      U.S. Long/Short Equity Fund
International Equity Fund             U.S. Discovery Fund                 U.S. Large/Mid Capitalization
European Fund                         International Small                 Long/Short Equity Fund
                                      Capitalization Fund                 Value Long/Short Equity Fund
                                                                          Global Long/Short Equity Fund

</Table>

The Performance Adjustment (whether positive or negative) for a Fund will never
exceed 5% of the advisory fee payable to CSIM with respect to such Fund (the
"Maximum Performance Adjustment"). The Maximum Performance Adjustment will be
made when the Fund's performance reaches plus or minus 2.0%, 4.0% and 5.0% in
relation to the relevant benchmark for funds falling within Groups A, B, and C,
respectively (the "Maximum Adjustment Performance Point"). The Performance
Adjustment will be zero when performance is in the Null Zone and, starting at
the edge of the Null Zone, it shall increase (or decrease in the case of a
negative Performance Adjustment) based on a constant ratio until the Maximum
Adjustment Performance Point is reached.

     ASSETS UNDER MANAGEMENT ADJUSTMENT (APPLICABLE TO ALL FUNDS EXCEPT THE
U.S. SMALL CAPITALIZATION FUND). The base sub-advisory fee will also be
adjusted in the event that the Funds collectively (excluding the AXA
Rosenberg U.S. Small Capitalization Fund) have not achieved assets under
management of at least $2.025 billion and the S&P 500 Index(R) is above
1,000. In this case, the base sub-advisory fee for the following year will be
increased for a period of one year by an amount equal to 5% of the gross base
investment advisory fee payable to CSIM with respect to each Fund.

In the event that the Funds collectively (excluding the AXA Rosenberg U.S.
Small Capitalization Fund) have not achieved assets under management of at
least $2.775 billion and the S&P 500 Index(R) is above 1,000, then the base
sub-advisory fee for the following year will be increased for a period of one
year by an amount equal to 5% of the gross base investment advisory fee
payable to CSIM with respect to each Fund.

For each year thereafter, in the event that (i) the Funds collectively
(excluding the Laudus Rosenberg U.S. Small Capitalization Fund) have not
achieved 50% of the End of Period Assets Under Management target (which shall
not be lower than the 2007 target) recommended by CSIM and AXA Rosenberg, and
(ii) the S&P 500 Index(R) is above 1,000, then the Sub-Advisory Base Fee will
be adjusted upward by an amount equal to 5% of the gross base investment
sub-advisory fee payable to CSIM with respect to each Fund.

In each case, the Performance Adjustment and the assets under management
adjustment will be made independently of each other.

TRUSTEES' CONSIDERATIONS

The Trustees, including the Independent Trustees, approved the Proposed
Subadviser Agreement for each Fund at a meeting held on November 3, 2003. The
Trustees also held meetings on September 10 and October 15, 2003 to consider
the agreement and ask questions of

                                       29
<Page>

representatives of CSIM and AXA Rosenberg. The Independent Trustees also held
separate meetings in person or by telephone on August 6, August 29, September
10, September 16, September 24 and October 15, 2003 to discuss each Proposed
Subadviser Agreement and other information provided by CSIM and AXA Rosenberg
pursuant to their requests. The Trustees received written and oral
information from AXA Rosenberg regarding AXA Rosenberg's key personnel. The
Trustees reviewed AXA Rosenberg's qualifications to act as sub-adviser and
its track record as investment adviser to the portfolios. In recommending
that shareholders approve each Proposed Subadviser Agreement, the Trustees
carefully evaluated the experience of AXA Rosenberg's key personnel in
institutional investing and the quality of services AXA Rosenberg is expected
to provide, and has in the past provided, to each Fund, including, but not
limited to: (1) the fee and expense ratios of comparable mutual funds,
including those that have sub-advisory relationships; (2) the performance of
the Funds since commencement of operations; (3) the nature and quality of
services expected to be rendered to each Fund by AXA Rosenberg; (4) the
distinct investment objectives and policies of the Funds; (5) the history,
reputation, qualification and background of AXA Rosenberg as well as the
qualifications of its personnel and its financial condition; (6) its
performance record; and (7) other factors deemed relevant. The Trustees also
reviewed the fees to be paid AXA Rosenberg under the agreement in comparison
to those being charged in the relevant segment of the mutual fund business
and considered the appropriateness of the weighting given to the fixed and
variable components of such fees. Also influencing the Board's decision were
considerations of whether the performance fee adjustments are reasonably
structured, and in particular whether they (a) will unduly reward AXA
Rosenberg for random short-term fluctuations in the market, (b) will be
measured against appropriate indices of securities, (c) will give rise to
significant costs in connection with the implementation or adjustment of such
indices, or (d) will give rise to volatility in AXA Rosenberg's fee revenues
that would have a significant impact on its financial health and, in
particular, on its ability to provide quality services to the Funds.

Based on this evaluation, the Trustees considered whether each Proposed
Subadviser Agreement would be in the best interests of each Fund and the
Fund's shareholders. One of the issues influencing the Trustees' decision was
that either AXA Rosenberg or its predecessor has been the investment adviser
to the Funds since their inception, and that it will continue to manage the
assets of each Fund on a day-to-day basis. Accordingly, for the reasons noted
above, together with other factors and information considered relevant, the
Trustees concluded that each Proposed Subadviser Agreement would be in the
best interest of each Fund and the Fund's shareholders.

reasonable time in advance of a proxy solicitation to be included. Submission of
a proposal does not guarantee inclusion in a proxy statement because proposals

                          FORM OF MANAGEMENT AGREEMENT

                           BARR ROSENBERG SERIES TRUST

                               MANAGEMENT CONTRACT

         Management Contract executed as of ________, 2003, between BARR
ROSENBERG SERIES TRUST, a Massachusetts business trust (the "Trust"), on behalf
of the Laudus Rosenberg _______________ Fund (the "Fund"), and CHARLES SCHWAB
INVESTMENT MANAGEMENT, INC., a Delaware corporation (the "Manager").

                                   WITNESSETH:

         That in consideration of the mutual covenants herein contained, it is
agreed as follows:

1.       SERVICES TO BE RENDERED BY MANAGER TO THE TRUST.

         (a)  Subject always to the control of the trustees of the Trust (the
"Trustees") and to such policies as the Trustees may determine, the Manager
will, at its expense, (i) furnish continuously an investment program for the
Fund and will make investment decisions on behalf of the Fund and place all
orders for the purchase and sale of its portfolio securities, and (ii) furnish
all necessary office space and equipment, provide bookkeeping and clerical
services required to perform its duties in clause (i) above and pay all
salaries, fees and expenses of the Trustees and officers of the Trust who are
affiliated persons of the Manager. In the performance of its duties, the Manager
will comply with the provisions of the Second Amended and Restated Agreement and
Declaration of Trust and By-laws of the Trust, each as amended from time to
time, and the Fund's stated investment objectives, policies and restrictions.

         (b)  In the selection of brokers, dealers or futures commissions
merchants (collectively, "brokers") and the placing of orders for the purchase
and sale of portfolio investments for the Fund, the Manager shall seek to obtain
the most favorable price and execution available, except to the extent it may be
permitted to pay higher brokerage commissions for brokerage and research
services as described below. In using its best efforts to obtain for the Fund
the most favorable price and execution available, the Manager, bearing in mind
the Fund's best interests at all times, shall consider all factors it deems
relevant, including, by way of illustration, the price, the size of the
transaction, the nature of the market for the security, the amount of the
commission, the timing of the transaction taking into account market prices and
trends, the reputation, experience and financial stability of the broker
involved and the quality of service rendered by the broker in other
transactions. Subject to such policies as the Trustees may determine, the
Manager shall not be deemed to have acted unlawfully or to have breached any
duty created by this Contract or otherwise solely by reason of its having caused
the Trust to pay, on behalf of the Fund, a broker that provides brokerage and
research services to the Manager or any affiliated person of the Manager an
amount of commission for effecting a portfolio investment transaction in excess
of the amount of commission another broker would have charged for effecting that
transaction, if the Manager determines in good faith that such amount of
commission was reasonable in relation to the value of the brokerage and research

                                     36
<Page>

services provided by such broker, viewed in terms of either that particular
transaction or the Manager's overall responsibilities with respect to the Fund
and to other clients of the Manager and any affiliated person of the Manager as
to which the Manager or any affiliated person of the Manager exercises
investment discretion.

         (c)  Notwithstanding Section 1(a) above and subject to the provisions
of the Second Amended and Restated Agreement and Declaration of Trust of the
Trust and the Investment Company Act of 1940, as amended (the "1940 Act"), the
Manager, at its expense, may select and contract with an investment sub-adviser
(the "Subadviser") for the Fund to perform, subject to the supervision of the
Manager, some or all of the services for which it is responsible pursuant to
paragraphs (a) and (b) of this Section 1 (including, but not limited to, the
selection of brokers). The Manager will compensate the Subadviser for its
services to the Fund.

         (d)  The Manager shall not be obligated to pay any expenses of or for
the Trust or of or for the Fund not expressly assumed by the Manager pursuant to
this Section 1 other than as provided in Section 3.

2.       OTHER AGREEMENTS, ETC.

         It is understood that any of the shareholders, Trustees, officers and
employees of the Trust may be a shareholder, partner, director, officer or
employee of, or be otherwise interested in, the Manager, and in any person
controlling, controlled by or under common control with the Manager, and that
the Manager and any person controlling, controlled by or under common control
with the Manager may have an interest in the Trust. It is also understood that
the Manager and persons controlling, controlled by or under common control with
the manager have and may have advisory, management service, distribution or
other contracts with other organizations and persons, and may have other
interests and businesses.

3.       COMPENSATION TO BE PAID BY THE TRUST TO THE MANAGER.

         The Fund will pay to the Manager as compensation for the Manager's
services rendered, for the facilities furnished and for the expenses borne by
the Manager pursuant to Section 1, a fee, computed and paid monthly at the
annual rate (based on the number of days elapsed through the end of the month)
of [__]% of the Fund's net asset value as of the last business day of the month.
Such fee shall be payable for each month within five (5) business days after the
end of such month.

         In the event that the expenses of the Fund exceed any expense
limitation which the Manager may, by written notice to the Trust, voluntarily
declare to be effective with respect to the Fund, subject to such terms and
conditions as the Manager may prescribe in such notice, the compensation due the
Manager shall be reduced, and, if necessary, the Manager shall bear the Fund's
expenses to the extent required by such expense limitation.

         If the Manager shall serve for less than the whole of a month, the
foregoing compensation shall be prorated.

                                        37

4.       ASSIGNMENT TERMINATES THIS CONTRACT; AMENDMENTS OF THIS CONTRACT.

         This Contract shall automatically terminate, without the payment of any
penalty, in the event of its assignment (as defined in the 1940 Act); and this
Contract shall not be materially amended unless such amendment is approved by
the affirmative vote of a majority of the outstanding shares of the Fund, and by
the vote, cast in person at a meeting called for the purpose of voting on such
approval, of a majority of the Trustees who are not interested persons of the
Trust or of the Manager.

parties to this agreement or "interested persons" (as defined in the 1940 Act)
of any such party, cast in person at a meeting called for the purpose of voting
on such approval, or (c) as otherwise permitted by the 1940 Act or the rules and
regulations thereunder. This Contract may be terminated at any time by a vote of
a majority of the Fund's outstanding voting securities or by a vote of a
majority of the Trust's entire Board of Trustees on 60 days' written notice to
the Manager or by the Manager on 60 days' written notice to the Trust. Unless
terminated automatically as set forth in Section 4, this Agreement may only be
terminated in accordance with the provisions of this Section 5.

         If the continuance of this Contract is submitted to the shareholders of
the Fund for their approval and such shareholders fail to approve such
continuance of this Contract as provided herein, the Manager may continue to
serve hereunder in a manner consistent with the 1940 Act and the rules and
regulations thereunder.

6.       CERTAIN DEFINITIONS

         For the purposes of this Contract, the "affirmative vote of a majority
of the outstanding shares" of the Fund means the affirmative vote, at a duly
called and held meeting of shareholders, (a) of the holders of 67% or more of
the shares of the Fund present (in person or by proxy) and entitled to vote at
such meeting, if the holders of more than 50% of the outstanding shares of the
Fund entitled to vote at such meeting are present in person or by proxy, or (b)
of the holders of more than 50% of the outstanding shares of the Fund entitled
to vote at such meeting, whichever is less.

approve at least annually" shall be construed in a manner consistent with the
1940 Act and the rules and regulations thereunder; and the term "brokerage and
research services" shall have the meaning given in the 1934 Act and the rules
and regulations thereunder.

7.       NONLIABILITY OF MANAGER.

         In the absence of willful misfeasance, bad faith or gross negligence on
the part of the Manager, or reckless disregard of its obligations and duties
hereunder, the Manager shall not be subject to any liability to the Trust, to
the Fund or to any shareholder, officer, director or Trustee thereof, for any
act or omission in the course of, or connected with, rendering services
hereunder.

8.       LIMITATION OF LIABILITY OF THE TRUSTEES AND SHAREHOLDERS.

         A copy of the Second Amended and Restated Agreement and Declaration of
Trust of the Trust is on file with the Secretary of State of The Commonwealth of

                     LAUDUS ROSENBERG _______________ FUND

                              SUBADVISER AGREEMENT

     Subadviser Agreement executed as of _________, 2003 among CHARLES SCHWAB
INVESTMENT MANAGEMENT, INC., a Delaware corporation (the "Manager"), AXA
ROSENBERG INVESTMENT MANAGEMENT LLC, a Delaware limited liability company (the
"Subadviser") and BARR ROSENBERG SERIES TRUST, a Massachusetts business trust
(the "Trust").

                                   WITNESSETH:

     That in consideration of the mutual covenants herein contained, it is
agreed as follows:

1.   SERVICES TO BE RENDERED BY SUBADVISER TO THE TRUST.

     (a)  Subject always to the control of the trustees of the Trust (the
"Trustees") and the supervision of the Manager, the Subadviser, at its expense,
will furnish continuously an investment program for the Laudus Rosenberg
_____________ Fund series of the Trust (the "Fund") and will make investment
decisions on behalf of the Fund and place all orders for the purchase and sale
of portfolio securities and all other investments, including exercising
discretion to select brokers and dealers to execute such transactions. For
avoidance of doubt, the Manager and the Trust hereby agree that the Manager
shall have no authority for the selection of brokers and/or the day-to-day
placing of orders in connection with the Fund, subject only to the Manager's
general supervisory obligations. In the performance of its duties, the
Subadviser (i) will comply with the provisions of the Trust's then-current
Declaration of Trust and By-laws, including any amendments thereto (upon receipt
of such amendments by the Subadviser), and the investment objectives, policies
and restrictions of the Fund as set forth in its then-current Prospectus and
Statement of Additional Information (copies of which will be supplied to the
Subadviser upon filing with the Securities and Exchange Commission) and (ii)
will comply with such investment guidelines as may be agreed upon from time to
time between the Trustees and the Subadviser. The Subadviser and the Manager
shall each make its officers and employees available to the other from time to
time at reasonable times to review investment policies of the Fund and to
consult with each other regarding the investment affairs of the Fund.

     (b)  The Subadviser, at its expense, will furnish (i) all necessary
investment and management facilities, including salaries of personnel, required
for it to execute its duties hereunder faithfully and (ii) administrative
facilities, including bookkeeping, clerical personnel and equipment necessary
for the efficient conduct of the investment affairs of the Fund, including
oversight of the pricing of the Fund's portfolio and reasonable assistance in
obtaining prices for portfolio securities (but excluding determination of net
asset value, shareholder accounting services and fund accounting services).

     (c)  In the selection of brokers, dealers or futures commissions merchants
(collectively, "brokers") and the placing of orders for the purchase and sale of
portfolio

                                       41
<Page>

investments for the Fund, the Subadviser shall comply with such policies
established by the Trustees and communicated to the Subadviser in writing and
shall seek to obtain for the Fund the most favorable price and execution
available, except to the extent it may be permitted to pay higher brokerage
commissions for brokerage and research services as described below. In using its
best efforts to obtain for the Fund the most favorable price and execution
available, the Subadviser, bearing in mind the Fund's best interests at all
times, shall consider all factors it deems relevant, including, by way of
illustration, price, the size of the transaction, the nature of the market for
the security, the amount of the commission, the timing of the transaction taking
into account market prices and trends, the reputation, experience and financial
stability of the broker involved and the quality of service rendered by the
broker in other transactions. Subject to such policies as the Trustees may
determine and communicate to the Subadviser in writing, the Subadviser shall not
be deemed to have acted unlawfully or to have breached any duty created by this
Agreement or otherwise solely by reason of its having caused the Fund to pay a
broker that provides brokerage and research services to the Subadviser or any
affiliated person of the Subadviser an amount of commission for effecting a
portfolio investment transaction in excess of the amount of commission another
broker would have charged for effecting that transaction, if the Subadviser
determines in good faith that such amount of commission was reasonable in
relation to the value of the brokerage and research services provided by such
broker, viewed in terms of either that particular transaction or the
Subadviser's overall responsibilities with respect to the Fund and to other
clients of the Subadviser and any affiliated person of the Subadviser as to
which the Subadviser or any affiliated person of the Subadviser exercises
investment discretion.

     (d)  The Subadviser shall not be obligated to pay any expenses of or for
the Trust or of or for the Fund not expressly assumed by the Subadviser pursuant
to this Section 1.

     (e)  The Subadviser will keep and maintain all books and records with
respect to the Fund's assets and transactions required by paragraph (f) of Rule
31a-1 under the Investment Company Act of 1940, as amended (the "1940 Act").
Subadviser will use commercially reasonable efforts to furnish to the Manager
any such information relating to Subadviser's services under this Agreement
needed by Manager and the Fund to keep and maintain the other books and records
of the Fund required by Rule 31a-1 under the 1940 Act. Subadviser will use
commercially reasonable efforts to furnish to Manager any other information
relating to the Fund's assets that must be filed by the Fund with the SEC or
sent to shareholders under the 1940 Act, and any exemptive or other relief
granted by the SEC. Subadviser agrees that all records that it maintains on
behalf of the Fund are property of the Fund, and Subadviser will surrender
promptly to Fund any of such records upon the Fund's request and at the Fund's
expense; provided, however, Subadviser may retain copies of such records. In
addition, Subadviser will preserve for the periods prescribed by Rule 31a-2
under the 1940 Act any such records as are required to be maintained by it
pursuant to this Agreement, and will transfer said records to any successor
subadviser upon its termination as subadviser (or, if there is no successor
subadviser, to the Manager.)

<Page>

     For the purposes of this Agreement, the terms "affiliated person",

7.   USE OF NAMES.

The Subadviser owns the right to use the names "Rosenberg" and "AXA Rosenberg"
in connection with investment-related services or products, and such names may

Subadviser. The Subadviser consents to the use by the Trust and the Manager of
the names "Rosenberg" in the name of the Fund and "AXA Rosenberg" in any
materials prepared in connection with the Fund, but only for so long as (i) this
agreement shall remain in full force (except that the Manager and the Fund shall
be permitted to use such names in reference to the Fund's former name and the
Subadviser's former role as subadvisor for a reasonable transition period of not
less than six months nor more than twelve months after the termination of this
Agreement and for periods thereafter as may be required for disclosure in a
regulatory filing, subject in each case to the Subadviser's prior approval,
which shall not be unreasonably withheld), and (ii) each of the Trust and
Manager shall fully perform, fulfill and comply with all provisions of this
agreement expressed herein to be performed, fulfilled or complied with by it. No
such name shall be used by the Trust or the Manager at any time or in any place
or for any purposes or under any conditions except as provided in this section.
The foregoing limited authorization by the Subadviser to the Trust and Manager
to use the names "Rosenberg" and/or "AXA Rosenberg" is not exclusive of the
right of the Subadviser itself to use, or to authorize others to use, said
names; the Trust and Manager acknowledge and agree that as among the Subadviser,
the Trust and the Manager, the Subadviser has the exclusive right to use, or to
authorize others to use, said names; and the Trust and Manager agree, on behalf
of the Fund, to take such action as may reasonably be requested by the
Subadviser to give full effect to the provisions of this section (including,
without limitation, consenting to such use of said names). Without limiting the
generality of the foregoing, the Trust and Manager agree that, upon any
termination of this agreement or upon the violation of any of its provisions by
the Trust or Manager, each of the Trust and Manager will use its best efforts to
change the name of the Trust and Fund so as to eliminate all reference, if any,
to the names "Rosenberg" and "AXA Rosenberg" and will not thereafter transact
any business in a name containing the name "Rosenberg" or "AXA Rosenberg" in any
form or combination whatsoever, or designate itself as the same entity as or
successor to an entity of such name, or otherwise use the name "Rosenberg" or
"AXA Rosenberg" or any other reference to the Subadviser, except as provided in
this section. Such covenants on the part of the Trust and Manager shall be
binding upon them, their trustees, directors, officers, stockholders, creditors
and all other persons claiming under or through it and shall survive the
termination of this Agreement.

     In the absence of willful misfeasance, bad faith or gross negligence on the
part of the Subadviser, or reckless disregard of its obligations and duties
hereunder, the Subadviser shall not be subject to any liability to the Manager,
to the Trust, to the Fund, or to any shareholder, officer, director or Trustee
thereof, for any act or omission in the course of, or connected with, rendering
services hereunder.

9.   EXERCISE OF VOTING RIGHTS.

     Except with the agreement or on the specific instructions of the Trustees
or the Manager, the Subadviser shall exercise or procure the exercise of any

personally delivered or mailed by registered mail, postage prepaid, to the other
party at such address as may be furnished in writing by such party.

11.  LIMITATION OF LIABILITY OF THE TRUSTEES AND SHAREHOLDERS.

     A copy of the Second Amended and Restated Agreement and Declaration of
Trust of the Trust is on file with the Secretary of State of The Commonwealth of
Massachusetts, and notice is hereby given that this instrument is executed on

                                SCHEDULE A - FEES

     (ALL FUNDS OTHER THAN THE AXA ROSENBERG U.S. SMALL CAPITALIZATION FUND)

     [The Manager will pay to the Subadviser as compensation for the services
rendered, the facilities furnished and the expenses borne by the Subadviser
pursuant to Section 1, in arrears for each calendar quarter, a fee, equal to
(1) the Sub-Advisory Base Fee (as defined below), plus or minus (2) the
Performance Adjustment (as defined below), if any.

1. The Sub-Advisory Base Fee shall be computed in arrears, with respect to any
calendar quarter, by multiplying each Quarterly Sub-Advisory Base Rate (as
defined below) for such quarter by the applicable tranche (as described below)
of the average daily net assets of the Fund over such quarter, and adding the
products thereof. Each Quarterly Sub-Advisory Base Rate for a particular quarter
shall equal the respective Annual Sub-Advisory Base Rate for such quarter
divided by four. The Annual Sub-Advisory Base Rates for any particular calendar
quarter shall equal (i) with respect to the Initial Tranche (as defined in
paragraph 2) of average daily net assets of the Fund, [45% of the gross annual
investment advisory rate payable to the Manager by the Fund (the "Investment
Advisory Contractual Rate") under the Management Agreement between the Manager
and the Fund]; (ii) with respect to the Second Tranche (as defined in paragraph
2) of average daily net assets of the Fund, [40% of the Investment Advisory
Contractual Rate]; and (iii) with respect to the Third Tranche (as defined in
paragraph 2) of average daily net assets of the Fund, [30% of the Investment
Advisory Contractual Rate]. The Sub-Advisory Base Fee for a partial quarter (if
this Agreement becomes effective or is terminated on other than the first or the
last day of a calendar quarter, respectively) shall be based on the average
daily net assets of the Fund over, and shall be prorated based on the number of
days in, such partial quarter.

2. The Initial Tranche of average daily net assets shall consist of all assets
up to [Fund assets as of closing date(1)], and notwithstanding any other
provision of this Schedule A, if, for any given quarter, the Fund's assets do
not exceed [Fund assets as of closing date], all of its average daily net
assets shall be in the Initial Tranche. If, and only if, the Fund's average
daily net assets over a quarter exceed [Fund assets as of closing date], the
Second Tranche of average daily net assets shall equal the Fund's PRO RATA
portion of the aggregate average daily net assets of all Funds sub-advised by
the Subadviser as of the closing date other than the AXA Rosenberg U.S. Small
Capitalization Fund (the "Existing Funds") that exceed [aggregate assets of
Existing Funds as of closing date] but do not exceed $2.5 billion (such
proration to be proportional to the relative excesses, if any for any
particular Fund, of the Existing Funds' average daily net assets for such
quarter over their respective assets as of the closing date (as set forth on
Schedule B to this Agreement)); provided, however, that if the assets as of
the closing date of any Existing Fund (as set forth on Schedule B) exceed
such Fund's average daily net assets over the relevant quarter, the amount of
such excess (the "Second Tranche Excess") shall be allocated PRO RATA

- --------
(1) References in this Schedule A to the assets of any one or more Funds as of
the closing date shall not include any assets over which the Sub-Adviser or its
affiliates have investment discretion (other than by virtue of Sub-Adviser's
position as investment adviser or sub-investment advisor to the relevant Fund)
that are redeemed out of the applicable Fund(s) within 90 days of the closing
date.

                                        47
<Page>

first among all other Existing Funds, including the Fund if applicable, that
have assets in excess of their respective assets as of the closing date (as set
forth on Schedule B)[, and, if such excess assets of the Existing Funds are
insufficient to permit full allocation of the Second Tranche Excess, the
remaining Second Tranche Excess shall be allocated PRO RATA among all Funds, if
any, sub-advised by the Subadviser that are not Existing Funds]; and provided
further that neither the Fund nor any other Existing Fund shall receive any
allocation of the Second Tranche Excess if its average daily net assets over the
quarter do not exceed [Fund assets as of closing date] (for the Fund) or such
Existing Fund's respective assets as of the closing date (as set forth on
Schedule B). Any portion of Second Tranche Excess allocated to the Fund for a
particular quarter shall be considered part of the Initial Tranche, as described
above, for purposes of calculating the Sub-Advisory Base Fee for such quarter.
If, and only if, the Fund's average daily net assets over a quarter exceed [Fund
assets as of closing date], the Third Tranche of average daily net assets shall
equal the Fund's PRO RATA portion of the aggregate average daily net assets of
the Existing Funds in excess of $2.5 billion (such proration to be proportional
to the average daily net assets for such quarter of those Existing Funds whose
average daily net assets exceed their respective assets as of the closing date
(as set forth on Schedule B)).

Example of Second Tranche Excess Allocation:
- -------------------------------------------

Assume three Funds with assets under management as of the closing date as
follows:

<Table>
<Caption>
                                                       
     Fund A              Fund B                Fund C              Total
     ------              ------                ------              -----
  $200 million        $300 million          $500 million        $1 billion
</Table>


Assume further average daily net assets over a quarter as follows:

<Table>
<Caption>
                                                       
      Fund A              Fund B                Fund C              Total
      ------              ------                ------              -----
   $300 million        $100 million          $900 million       $1.3 billion
</Table>

In this example, all of Fund B's average daily net assets over the quarter would
be in its Initial Tranche because they fall short of its assets under management
as of the closing date. The difference between Fund B's assets as of the closing
and its average daily net assets over the quarter ($200 million) constitutes
Second Tranche Excess, which would be allocated between Fund A and Fund C (each
of which has average daily net assets over the quarter that exceed its
respective assets under management as of the closing date) PRO RATA according to
the amount of such excesses. The excesses equal, for Fund A, $300 - $200 million
= $100 million, and for Fund C, $900 million - $500 million = $400 million, so
the $200 million shortfall from Fund B would be allocated according to a 1:4
ratio between Fund A and Fund C, respectively, or $40 million to Fund A and $160
million to Fund C. Accordingly, $240 million of Fund A and $660 million of Fund
C, together with Fund B's $100 million, or a total of $1 billion, would be
Initial

                                        48
<Page>

Tranche assets.  The remaining $60 million of Fund A and $240 million of Fund C,
or a total of $300 million, would be in the Second Tranche of those Funds.

3. The Sub-Advisory Base Fee shall be subject to upward adjustment for each
quarter in calendar year 2008 if, (a) as of 4:00 p.m. Eastern time on the last
business day of 2007, the aggregate assets under management for all Paragon
Funds sub-advised by the Subadviser (excluding assets of the AXA Rosenberg U.S.
Small Capitalization Fund ("Small Cap Fund Assets")) do not exceed
$2,025,000,000, and (b) the S&P 500 Index is above 1000. Such upward adjustment
shall equal the product of (a) [5% of the Investment Advisory Contractual Rate],
and (b) the average daily net assets of the Fund over such quarter. The
Sub-Advisory Base Fee shall also be subject to upward adjustment for each
quarter in calendar year 2009 if, (a) as of 4:00 p.m. Eastern time on the last
business day of 2008, the aggregate assets under management for all Paragon
Funds sub-advised by the Subadviser (excluding the Small Cap Fund Assets) do not
exceed $2,777,777,777.50, and (b) the S&P 500 Index is above 1000. Such upward
adjustment shall equal the product of (a) [5% of the Investment Advisory
Contractual Rate], and (b) the average daily net assets of the Fund over such
quarter. The Sub-Advisory Base Fee shall also be subject to upward adjustment
for each quarter of each calendar year beginning with 2010 if, (a) as of 4:00
p.m. Eastern time on the last business day of the previous calendar year, the
aggregate assets under management for all Paragon Funds sub-advised by the
Subadviser (excluding the Small Cap Fund Assets) do not exceed 50% of the
aggregate assets under management target for such year for such Funds
established from time to time in the manner as may be agreed upon by Manager and
Subadviser (provided always that such aggregate target amount shall not be less
than $4,050,000,000), and (b) the S&P 500 Index is above 1000. Such upward
adjustment shall equal the product of (a) [5% of the Investment Advisory
Contractual Rate], and (b) the average daily net assets of the Fund over such
quarter.

4. The Performance Adjustment, if any, for any particular calendar quarter shall
also be calculated in arrears and shall be equal to the product of (a) the
Adjustment Rate (as defined below), (b) [the Investment Advisory Contractual
Rate divided by four], and (c) the average daily net assets of the Fund over
such quarter. The Adjustment Rate shall equal the product of (x) the Adjustment
Factor (as defined below), and (y) (i) the Performance Difference for such
quarter, (ii) (A) minus [100 bps for Group A Funds, 200 bps for Group B Funds,
250 bps for Group C Funds-- i.e., the top of the null zone], if such Performance
Difference is positive, or (B) plus [100 bps for Group A Funds, 200 bps for
Group B Funds, 250 bps for Group C Funds], if such Performance Difference is
negative; provided, however, that the Adjustment Rate shall equal zero (and
accordingly there shall be no Performance Adjustment) in the event that the
Performance Difference is neither greater than [1%, 2%, 2.5% ] nor less than
negative [1%, 2%, 2.5%]; and provided further that the Adjustment Rate shall be
neither greater than positive 5% nor less than negative 5%. For purposes of the
foregoing, the Adjustment Factor shall be equal to [5 for Group A Funds, 2.5 for
Group B Funds, 2 for Group C Funds]; the term "Performance Difference" for any
particular quarter shall mean the difference between the Fund's Investment
Performance (as defined below) for the Rolling Period (as defined below) ending
on the last day of the quarter, and the Record (as defined below) of [the
relevant benchmark] for the same rolling period; the term "Investment
Performance" shall mean the daily-compounded rate of return, reflecting all
income, dividends and capital actions as of the date occurring or earned by the
Fund, net of all expenses of the Fund, expressed as a percentage; the term
"Record" shall

                                        49
<Page>

mean the total return of [the relevant index], expressed as a percentage; and
the term "Rolling Period" shall mean a period consisting of twelve calendar
quarters, [or such shorter period as has elapsed since [closing date],] with
the most recent quarter substituted for the earliest such quarter as time
passes[, but in no event shall the "rolling period" be less than four calendar
quarters].]
