                                 PROXY STATEMENT

      The enclosed proxy is solicited on behalf of the Board of Trustees (the
"Trustees") of One Group[RegTM] Mutual Funds (the "Trust") on behalf of One
Group High Yield Bond Fund (the "High Yield Bond Fund") and One Group Income
Bond Fund (the "Income Bond Fund"). The proxy is revocable at any time before it

proxy to the Trust at the above address or by appearing personally and electing
to vote on February 26, 2003 at the Special Meeting of Shareholders of the High
Yield Bond Fund and the Income Bond Fund (collectively, the "Funds") at 10:00
a.m. (Eastern Time) at 1111 Polaris Parkway, Suite 2-J, Columbus, Ohio 43271
(such meeting and any adjournment thereof is referred to herein as the "Special
Meeting"). The cost of preparing and mailing the Notice of Special Meeting, the
proxy card, this proxy statement and any additional proxy material has been or
is to be borne jointly by Banc One Investment Advisors Corporation and Banc One
High Yield Partners, LLC. Proxy solicitations will be made primarily by mail,
but may also be made by telephone, internet, or personal interview conducted by
certain officers or employees of the Trust or One Group Administrative Services,
Inc. (the Trust's administrator pursuant to a Management and Administration
Agreement between One Group Administrative Services, Inc. and the Trust). In the
event that the Shareholder signs and returns the proxy ballot, but does not
indicate a choice as to any of the items on the proxy ballot, the proxy
attorneys will vote those Shares in favor of such proposal(s).

      Only Shareholders of record at the close of business on December 13, 2002
will be entitled to vote at the Special Meeting. On December 13, 2002, the High
Yield Bond Fund had 86,343,163.453 shares outstanding and the Income Bond Fund
had 170,906,405.437 shares outstanding. Each Share of each Fund is entitled to
one vote, with each fractional share being entitled to a proportionate
fractional vote on each matter to be acted upon at the Special Meeting. This
proxy statement and the enclosed proxy card will be sent to Shareholders of
record on or about January 10, 2003.

      One Group Mutual Funds' Declaration of Trust and Code of Regulations do
not provide for annual shareholder meetings, and no such meetings are planned
for 2003. Proposals that shareholders would like to have included in a proxy
statement for any future meeting must be received by One Group Mutual Funds
within a reasonable period of time prior to printing and mailing proxy material
for such meeting.

      For purposes of determining the presence of a quorum and counting votes on
the matters presented, Shares represented by abstentions and "broker non-votes"
will be


counted as present, but not as votes cast, at the Special Meeting. Under the
Investment Company Act of 1940, as amended (the "1940 Act"), the affirmative
vote necessary to approve the matter under consideration may be determined with
reference to a percentage of votes present at the Special Meeting, which would
have the effect of treating abstentions and non-votes as if they were votes
against the proposal.

      COPIES OF THE FUNDS' ANNUAL REPORT DATED JUNE 30, 2002 ARE AVAILABLE UPON

      Each Fund votes separately. Approval of each of the Proposals requires the
affirmative vote of the lesser of: (a) 67% or more of the outstanding Shares of
the applicable Fund present at the Special Meeting, if the holders of more than
50% of the outstanding Shares are present or represented by proxy, or (b) more
than 50% of the outstanding Shares of the applicable Fund.

              BACKGROUND INFORMATION FOR PROPOSAL 1 AND PROPOSAL 2

      Investment Advisory Agreement with Banc One Investment Advisors. Banc One
Investment Advisors Corporation ("Banc One Investment Advisors") serves as
investment advisor to the Funds pursuant to an investment advisory agreement
dated January 11, 1993 (the "Investment Advisory Agreement"). The Investment
Advisory Agreement will continue in effect as to the Funds from year to year, if
such continuance is approved at least annually by the Trust's Board of Trustees
or by vote of a majority of the outstanding shares of the High Yield Bond Fund
and the Income Bond Fund and, in either case, by a majority of the Trustees who
are not interested persons as defined in the 1940 Act, by vote cast in person at
a meeting called for such purpose. The Trust's Board of Trustees renewed the
Investment Advisory Agreement at their quarterly meeting on August 15, 2002. The
Investment Advisory Agreement may be terminated without penalty as to either
Fund at any time on 60 days' written notice by the Trustees, by vote of a
majority of the outstanding shares of that Fund, or by Banc One Investment
Advisors. The Investment Advisory Agreement also terminates automatically in the
event of any assignment, as defined in the 1940 Act.

      Under the Investment Advisory Agreement, Banc One Investment Advisors
makes the day-to-day investment decisions for the Funds and continuously
reviews, supervises and administers the Funds' investment programs. As
consideration for its


                                       3


services, Banc One Investment Advisors is entitled to a fee at the annual rate
of seventy-five one-hundredths of one percent (.75%) of the High Yield Bond
Fund's daily net assets and sixty one-hundredths of one percent (.60%) of the
Income Bond Fund's daily net assets. For the period beginning November 1, 2002
and ending October 31, 2003, Banc One Investment Advisors and the Fund's
administrator, One Group Administrative Services, Inc. have contractually agreed
to waive fees and/or reimburse expenses to limit total annual fund operating
expenses to 1.15% for Class A shares, 1.80% for Class B shares, 1.80% for Class
C shares, and .90% for Class I shares of the High Yield Bond Fund and to .92%
for Class A shares, 1.57% for Class B shares, 1.57% for Class C shares, and .67%
for Class I shares of the Income Bond Fund. For the fiscal year ended June 30,
2002, the High Yield Bond Fund and the Income Bond Fund paid investment advisory
fees to Banc One Investment Advisors equal to $2,818,000 and $5,975,000,
respectively after taking into account fee waivers/reimbursements.

      Banc One Investment Advisors has full responsibility for providing
investment advisory services to the High Yield Bond Fund and the Income Bond
Fund. However, Banc One Investment Advisors has discharged this responsibility
in part through retention of Banc One High Yield Partners, LLC ("Banc One High
Yield Partners") as sub-advisor under Investment Sub-Advisory Agreements between
Banc One Investment Advisors and Banc One High Yield Partners (collectively, the
"Current Sub-Investment Advisory Agreements"). The Current Sub-Investment
Advisory Agreements were renewed through August 31, 2003 at the Board's regular
quarterly meeting on August 15, 2002. Banc One Investment Advisors is solely
responsible for paying sub-advisory fees to Banc One High Yield Partners at its
own expense. As described below in detail, the Current Sub-Investment Advisory
Agreements may be deemed to terminate due to a change in control of one of the
owners of Banc One High Yield Partners. Approval of the Proposal 1 and Proposal
2 will allow the continuation of Banc One High Yield Partners' appointment as
sub-advisor for the High Yield Bond Fund and the Income Bond Fund.

      Termination of Current Sub-Investment Advisory Agreements. As required by
the 1940 Act, each of the Current Sub-Investment Advisory Agreements contain a
provision providing for their automatic termination in the event of an
"assignment." Under the 1940 Act, a change in control of an investment advisor
(including a sub-advisor) results in an assignment and termination of the
investment advisor's investment advisory agreements. As described below, one of
the members of Banc One High Yield Partners will undergo a change in control
upon consummation of a proposed transaction. Such a change in control could be
deemed to result in the assignment of, and therefore the termination of, the
Current Sub-Investment Advisory Agreements. To avoid any uncertainty about the
status of the Current Sub-Investment Advisory Agreements, the Board of Trustees
of One Group Mutual Funds believes that it is in the best interests of the High
Yield Bond Fund and the Income Bond Fund to obtain shareholder approval of new
Sub-Investment Advisory Agreements (the "New


                                       4


Sub-Investment Advisory Agreements"). AS DISCUSSED BELOW, NEITHER BANC ONE HIGH
YIELD PARTNERS NOR THE PERSONNEL RESPONSIBLE FOR PROVIDING SUB-ADVISORY SERVICES
TO THE FUNDS, NOR THE SERVICES PROVIDED TO THE FUNDS, WILL CHANGE DUE TO THE
PROPOSED TRANSACTION. EACH OF THE PROPOSED NEW SUB-INVESTMENT ADVISORY
AGREEMENTS CONTAIN TERMS SUBSTANTIALLY THE SAME TO THOSE IN THE CURRENT
SUB-INVESTMENT ADVISORY AGREEMENTS.

      Summary of the Proposed Transaction. Banc One Investment Advisors, an
indirect wholly-owned subsidiary of Bank One Corporation, owns 51% of the equity
interest in Banc One High Yield Partners, and Pacholder Associates, Inc.,
located at 8044 Montgomery Road, Suite 480, Cincinnati, Ohio, owns the remaining
49%. Currently, Asher O. and Sylvia A. Pacholder (the "Pacholders") own
approximately 60% of the shares of Pacholder Associates, Inc. The remainder of
Pacholder Associates, Inc. is owned by William J. Morgan, President of Pacholder
Associates, Inc, and other employees of Pacholder Associates, Inc. The
Pacholders propose to withdraw as shareholders of Pacholder Associates, Inc. in
a transaction that will result in the redemption of their shares, the issuance
of new shares to William J. Morgan and other employees of Pacholder Associates,
Inc., and the issuance of a convertible note to Bank One Corporation (the
"Proposed Transaction"). The note would be immediately convertible by Bank One
Corporation into up to approximately 40% of the total outstanding common shares
of Pacholder Associates, Inc. on a fully diluted basis. Bank One Corporation
also would receive an option to acquire all of the outstanding shares of
Pacholder Associates, Inc. that is exercisable after five years. In connection
with the Proposed Transaction, the Pacholders would resign all positions held
with Pacholder Associates, Inc., including their positions as members of the
company's board of directors.

      The 1940 Act provides a rebuttable presumption that the direct or indirect
owner of more than 25% of the outstanding shares of an entity controls that
entity. Because Pacholder Associates, Inc. may be deemed to control Banc One
High Yield Partners, the change in control of Pacholder Associates, Inc. may be
deemed to result in a change in control of Banc One High Yield Partners. Based
largely on this presumption, Banc One Investment Advisors has advised the Funds'
Board of Trustees that it believes that consummation of the Proposed Transaction
may cause an assignment of the Current Sub-Investment Advisory Agreements. To
avoid any uncertainty about the status of the Current Sub-Investment Advisory
Agreements, the Funds' Board of Trustees believes that it is prudent and in the
best interest of the Funds to obtain shareholder approval of New Sub-Investment
Advisory Agreements. Approval of New Sub-Investment Advisory Agreements is a
condition precedent to the closing of the Proposed Transaction. As a result, the
Proposed Transaction will not be consummated unless this condition is waived or
deferred by Bank One Corporation.

      THE PROPOSED TRANSACTION WOULD NOT RESULT IN ANY CHANGE TO BANC ONE HIGH
YIELD PARTNERS' PERSONNEL, DAY-TO-DAY MANAGEMENT OF THE FUNDS OR FINANCIAL


                                       5


CONDITION. BANC ONE HIGH YIELD PARTNERS' BOARD OF MANAGERS WOULD RETAIN ITS
EXISTING COMPOSITION, AS SET FORTH IN INFORMATION ABOUT BANC ONE HIGH YIELD
PARTNERS, LLC.

      Basis for Approval of the New Sub-Investment Advisory Agreements. In
reviewing Banc One High Yield Partners and the New Sub-Investment Advisory
Agreements, the Funds' Board of Trustees, including the independent Trustees,
considered the best interests of Shareholders of the Funds and took into account
all factors they deemed relevant. The Trustees considered the experience,
research methodology and portfolio management staffing provided by Banc One High
Yield Partners in managing high yield assets. The Trustees also considered
performance in the context of other high yield bond funds. Finally, the Trustees
considered whether the Proposed Transaction would have a material impact on Banc
One High Yield Partners' services to the Funds and concluded that it would not,
given that there will be no change in Banc One High Yield Partner's portfolio
management staff. Based on these factors, the Trustees unanimously approved the
proposed New Sub-Investment Advisory Agreements.

           PROPOSAL (1) -- APPROVAL OF A NEW SUB-INVESTMENT ADVISORY
             AGREEMENT FOR THE HIGH YIELD BOND FUND BETWEEN BANC ONE
              INVESTMENT ADVISORS AND BANC ONE HIGH YIELD PARTNERS

      Banc One High Yield Partners currently provides sub-advisory services to
the High Yield Bond Fund pursuant to a Current Sub-Investment Advisory
Agreement, dated as of August 20, 1998 between Banc One Investment Advisors and
Banc One High Yield Partners. On May 16, 2002, the Trustees of the Trust,
including a majority of the Trustees who are not interested persons of the Trust
or Banc One High Yield Partners, as defined in the 1940 Act, unanimously
approved on behalf of the High Yield Bond Fund the form of a New Sub-Investment
Advisory Agreement between Banc One Investment Advisors and Banc One High Yield
Partners. (A copy of this form of the proposed New Sub-Investment Advisory
Agreement between Banc One Investment Advisors and Banc One High Yield Partners
is included as Exhibit A to this proxy statement). Under the New Sub-Investment
Advisory Agreement, Banc One High Yield Partners would continue to serve as
Sub-Advisor to the High Yield Bond Fund.

The Current and New Sub-Investment Advisory Contracts

      EXCEPT FOR RENEWAL AND EFFECTIVE DATES AND A PROVISION REQUIRING BANC ONE
HIGH YIELD PARTNERS TO CONTRACTUALLY WAIVE FEES, THE CURRENT AND NEW
SUB-INVESTMENT ADVISORY AGREEMENTS ARE THE SAME IN ALL MATERIAL RESPECTS. In
connection with both agreements, Banc One Investment Advisors retains full
responsibility for providing investment advisory services to the High Yield Bond
Fund. Under both agreements, Banc One Investment Advisors discharges this
responsibility in part through retention of Banc One High Yield Partners, at
Banc One Investment Advisors' sole expense. Subject always to the instructions
and supervision


                                       6


of Banc One Investment Advisors, Banc One High Yield Partners provides a
continuous investment program for the High Yield Bond Fund, including investment
research and management with respect to all of the Fund's assets. Banc One High
Yield Partners places all orders for purchases and sales of the High Yield Bond
Fund's securities. Banc One High Yield Partners bears the same expenses
expressly stated to be payable by it under both agreements.

      As full compensation for the services provided and expenses assumed under
both the current and new agreement, Banc One Investment Advisors is obligated to
pay Banc One High Yield Partners a fee, computed daily and paid monthly, at an
annual rate of seventy one-hundredths of one percent (.70%) of the High Yield
Bond Fund's average daily net assets. Under the New Sub-Investment Advisory
Agreement, Banc One High Yield Partners agrees to waive a portion of the
sub-advisory fee equal to the percentage of the investment advisory fee waived
by Banc One Investment Advisors under the Investment Advisory Agreement. Banc
One Investment Advisors bears the sole responsibility for the payment of Banc
One High Yield Partners' fee under both the Current and New Sub-Investment
Advisory Agreements. For the fiscal year ended June 30, 2002, Banc One
Investment Advisors paid Banc One High Yield Partners $1,972,790 for its
services under the Current Sub-Investment Advisory Agreement for the High Yield
Bond Fund, after taking into account fee waivers/ reimbursements.

      Both the Current and the New Sub-Investment Advisory Agreements continue
for successive one-year terms, provided that such continuation is specifically
approved at least annually by a vote of a majority of the Trustees, or by the
vote of a majority of the outstanding Shares of the Fund, and, in either case,
by a majority of the Trustees who are not interested persons as defined in the
1940 Act, by vote cast in person at a meeting called for such purpose. Both
agreements also terminate automatically in the event of their assignment, as
defined in the 1940 Act or upon termination of the Investment Advisory
Agreement.

      If the New Sub-Investment Advisory Agreement is approved by the
shareholders of the High Yield Bond Fund, it will become effective upon
termination of the Current Sub-Investment Advisory Agreement in accordance with
its terms, which would occur upon consummation of the Proposed Transaction. If
the Proposed Transaction is not consummated, the Current Sub-Investment Advisory
Agreement will remain in effect until otherwise terminated.

      The Trustees recommend that the Shareholders of the High Yield Bond Fund
vote to approve the proposed New Sub-Investment Advisory Agreement, thereby
continuing the appointment of Banc One High Yield Partners as the Sub-Advisor to
the High Yield Bond Fund. Approval by Shareholders of the New Sub-Investment
Advisory Agreement will not result in an increase in the contractual rate of any
advisory or sub-investment advisory fees payable by the Fund, but will result in
the continued payment of the sub-investment advisory fees by Banc One Investment


                                       7


Advisors to Banc One High Yield Partners. Such sub-investment advisory fees are
borne solely by Banc One Investment Advisors and not by the Fund.

      In the event that holders of a majority of the outstanding Shares of the
Fund vote in the negative with respect to the proposed New Sub-Investment
Advisory Agreement, the Current Sub-Investment Advisory Agreement will remain in
effect until terminated in accordance with its terms and the Trustees will
consider such further action as they may determine to be in the best interests
of the Fund's Shareholders.

        THE TRUSTEES UNANIMOUSLY RECOMMEND THAT SHAREHOLDERS OF THE FUND
       VOTE TO APPROVE THE PROPOSED NEW SUB-INVESTMENT ADVISORY AGREEMENT.

           PROPOSAL (2) -- APPROVAL OF A NEW SUB-INVESTMENT ADVISORY
               AGREEMENT FOR THE INCOME BOND FUND BETWEEN BANC ONE
              INVESTMENT ADVISORS AND BANC ONE HIGH YIELD PARTNERS

      Banc One High Yield Partners currently provides sub-advisory services to
the Income Bond Fund pursuant to a Current Sub-Investment Advisory Agreement,
dated as of November 19, 1999 between Banc One Investment Advisors and Banc One
High Yield Partners. The Current Sub-Investment Advisory Agreement was approved
by the Income Bond Fund's shareholders on November 19, 2000. On May 16, 2002,
the Trustees of the Trust, including a majority of the Trustees who are not
interested persons of the Trust or Banc One High Yield Partners, as defined in
the 1940 Act, unanimously approved on behalf of the Income Bond Fund the form of
a new Sub-Investment Advisory Agreement (the "New Sub-Investment Advisory
Agreement") between Banc One Investment Advisors and Banc One High Yield
Partners. (A copy of this form of this proposed New Sub-Investment Advisory
Agreement between Banc One Investment Advisors and Banc One High Yield Partners
is included as Exhibit B to this proxy statement). Under the New Sub-Investment
Advisory Agreement, Banc One High Yield Partners would continue to serve as
Sub-Advisor to the Income Bond Fund.

The Current and New Sub-Investment Advisory Contracts

      EXCEPT FOR RENEWAL AND EFFECTIVE DATES, THE CURRENT AND NEW SUB-INVESTMENT
ADVISORY AGREEMENTS ARE THE SAME IN ALL MATERIAL RESPECTS. In connection with
both agreements, Banc One Investment Advisors retains full responsibility for
providing investment advisory services to the Income Bond Fund. Under both
agreements, Banc One Investment Advisors discharges this responsibility in part
through retention of Banc One High Yield Partners, at Banc One Investment
Advisors' sole expense to manage those assets of the Fund that are designated
from time to time by Banc One Investment Advisors for investment in corporate
fixed-income securities and instruments rated below investment grade or unrated
corporate fixed-income securities and instruments of similar quality
(collectively, "High Yield Assets"). (Currently, up to 30% of the Fund's total
assets may be invested in High Yield Assets). Banc One


                                       8


Investment Advisors is required to oversee the activities of Banc One High
Yield Partners as well as designating the assets of the Income Bond Fund to be
managed by Banc One High Yield Partners.

      Under both agreements, Banc One High Yield Partners, in accordance with
the Fund's objective, policies and restrictions, and subject to the general
supervision of the Trustees and Banc One Investment Advisors, is required to
manage the day-to-day investment activities for those assets designated as
eligible for investment in High Yield Assets by Banc One Investment Advisors
(the "High Yield Portfolio"). Both agreements require Banc One High Yield
Partners to make investment decisions concerning, and place all orders for,
purchases and sales of the High Yield Portfolio's securities and maintain the
High Yield Portfolio's records relating to such purchases and sales. Banc One
High Yield Partners bears the same expenses expressly stated to be payable by it
under both agreements.

      As full compensation for the services provided and expenses assumed under
both the current and new agreements, Banc One Investment Advisors is obligated
to pay Banc One High Yield Partners a fee, computed daily and paid monthly, at
an annual rate of sixty one-hundredths of one percent (.60%) of the High Yield
Portfolio's average daily net assets. Under both agreements, Banc One High Yield
Partners agrees to waive a portion of the sub-advisory fee in an amount equal to
the percentage of the advisory fee waived by Banc One Investment Advisors under
the Investment Advisory Agreement. Banc One Investment Advisors bears the sole
responsibility for the payment of this fee to Banc One High Yield Partners. For
the fiscal year ended June 30, 2002. Banc One Investment Advisors paid Banc One
High Yield Partners $184,228 for its services under the Current Sub-Investment
Advisory Agreement for the Income Bond Fund, after taking into account fee
waivers/reimbursements.

      Both the Current and the New Sub-Investment Advisory Agreements continue
for successive one-year terms, provided that such continuation is specifically
approved at least annually by a vote of a majority of the Trustees, or by the
vote of a majority of the outstanding Shares of the Fund, and, in either case,
by a majority of the Trustees who are not interested persons as defined in the
1940 Act, by vote cast in person at a meeting called for such purpose. Both
agreements also terminate automatically in the event of their assignment, as
defined in the 1940 Act or upon termination of the Investment Advisory
Agreement.

      If the New Sub-Investment Advisory Agreement is approved by the
shareholders of the Income Bond Fund, it will become effective upon termination
of the Current Sub-Investment Advisory Agreement in accordance with its terms,
which would occur upon consummation of the Proposed Transaction. If the Proposed
Transaction is not consummated, the Current Sub-Investment Advisory Agreement
will remain in effect until otherwise terminated.


                                       9


      The Trustees recommend that the Shareholders of the Income Bond Fund vote
to approve the proposed New Sub-Investment Advisory Agreement, thereby
continuing the appointment of Banc One High Yield Partners as the Sub-Advisor to
the Income Bond Fund. Approval by Shareholders of the New Sub-Investment
Advisory Agreement will not result in an increase in the contractual rate of any
advisory or sub-investment advisory fees payable by the Fund, but will result in
the payment of the sub-investment advisory fees by Banc One Investment Advisors
to Banc One High Yield Partners. Such sub-investment advisory fees are borne
solely by Banc One Investment Advisors and not by the Fund.

      In the event that holders of a majority of the outstanding Shares of the
Fund vote in the negative with respect to the proposed New Sub-Investment
Advisory Agreement, the Current Sub-Investment Advisory Agreement will remain in
effect until terminated in accordance with its terms and the Trustees will
consider such further action as they may determine to be in the best interests
of the Fund's Shareholders.

        THE TRUSTEES UNANIMOUSLY RECOMMEND THAT SHAREHOLDERS OF THE FUND
       VOTE TO APPROVE THE PROPOSED NEW SUB-INVESTMENT ADVISORY AGREEMENT.

      3. Management. Subject always to the instructions and supervision of the
Investment Adviser and the Trust's Board of Trustees, the Sub-Adviser will
provide a continuous investment program for the Fund, including investment

equivalents in the Fund. The Sub-Adviser will determine from time to time what
securities and other investments will be purchased, retained or sold by the

behalf of the Trust with respect to the Fund. The Sub-Adviser will provide the
services under this Agreement in accordance with the Fund's investment
objective, policies and restrictions as stated in the Prospectus and resolutions
of the Trust's Board of Trustees. The Sub-Adviser further agrees that it:

                  (a) will use the same skill and care in providing such
            services as it uses in providing services to fiduciary accounts for
            which it has investment responsibilities;


                                      A-2


                  (b) will comply in all material respects with all applicable
            Rules and Regulations of the Securities and Exchange Commission and
            in addition will conduct its activities under this Agreement in
            accordance with any applicable regulations pertaining to the

            determinations for the Fund either directly with the issuer or with

            the Sub-Adviser will attempt to obtain prompt execution of orders in
            an effective manner at the most favorable price. Consistent with
            this obligation, when the execution and price offered by two or more
            brokers or dealers are comparable, the Sub-Adviser may, in its
            discretion, purchase and sell portfolio securities to and from
            brokers and dealers who provide the Sub-Adviser with research advice
            and other services. In no instance will portfolio securities be
            purchased from or sold to One Group Dealer Services, Inc., the
            Investment Adviser, the Sub-Adviser or any affiliated person of
            either the Trust, One Group Dealer Services, Inc., the Investment
            Adviser, or the Sub-Adviser, except to the extent permitted by the
            1940 Act;

                  (e) will treat confidentially and as proprietary information
            of the Trust all records and other information relative to the Fund
            and prior, present or potential shareholders, and will not use such
            records and information for any purpose other than in the
            performance of its responsibilities and duties hereunder, except
            after prior notification to and approval in writing by the Trust,
            which approval shall not be unreasonably withheld. The foregoing
            shall not apply to any information that is publicly available when
            provided or thereafter becomes publicly available other than through
            a breach of this Agreement, or that is required or requested to be
            disclosed by the Securities and Exchange Commission or any other
            regulatory examiner of the Sub-Adviser, any auditor of the parties
            hereto, by judicial or administrative process or otherwise by
            applicable law or regulation. Nothing herein shall restrict the
            Sub-Adviser's ability to publish information regarding the
            performance of accounts under its management; and

                  (f) will maintain its policy and practice of conducting its
            fiduciary functions independently. In making investment
            recommendations for the Fund, the Sub-Adviser's personnel will not
            inquire or take into consideration whether the issuers of securities
            proposed for purchase or sale for the Fund's account are customers
            of the Investment Adviser, the Sub-Adviser or the parents or
            subsidiaries or affiliates of the Investment Adviser or Sub-Adviser.
            In dealing with such customers, the Sub-Adviser and its parent,
            subsidiaries,


                                      A-3


            and affiliates will not inquire or take into consideration whether
            securities of those customers are held by the Trust.

      4. Services Not Exclusive. The investment advisory services furnished by
the Sub-Adviser hereunder are not to be deemed exclusive. Except to the extent
necessary to perform the Sub-Adviser's obligations under this Agreement, nothing
herein shall be deemed to limit or restrict the right of the Sub-Adviser, or any
subsidiary or affiliate of the Sub-Adviser, or any employee of the Sub-Adviser,
to engage in any other business, whether of a similar or dissimilar nature, or
to render services of any kind to any other person.

      5. Books and Records. In compliance with the requirements of Rule 3la-3
under the 1940 Act, the Sub-Adviser hereby agrees that all records which it
maintains for the Trust are the property of the Trust and further agrees to
surrender promptly to the Trust any of such records upon the Trust's request.
The Sub-Adviser further agrees to preserve for the periods prescribed by Rule
3la-2 under the 1940 Act all records which it maintains for the Fund that are
required to be maintained by Rule 3la-1 under the 1940 Act.

      6. Expenses. During the term of this Agreement, the Sub-Adviser will pay
all expenses incurred by it in connection with its activities under this
Agreement other than the cost of securities (including brokerage commissions, if
any) purchased for the Trust. The Trust and the Investment Adviser will be
responsible for all of their respective expenses and liabilities.

      7. Compensation. For the services provided and the expenses assumed
pursuant to this Agreement, the Investment Adviser will pay the Sub-Adviser and
the Sub-Adviser will accept as full compensation therefor a fee computed daily
and paid monthly in arrears on the first business day of each month at an annual
rate of seventy one-hundredths of one percent (0.70%) of the Fund's average
daily net assets. (The Sub-Adviser agrees to waive a portion of the sub-advisory
fee equal to the percentage of the investment advisory fee waived by the
Investment Adviser under the Investment Advisory Agreement between the Trust and
the Investment Adviser.)

      If the fee payable to the Sub-Adviser pursuant to this Section 7 begins to
accrue before the end of any month or if this Agreement terminates before the
end of any month, the fee for the period from such date to the end of such month
or from the beginning of such month to the date of termination, as the case may
be, shall be prorated according to the proportion which such period bears to the
full month in which such effectiveness or termination occurs. For purposes of
calculating fees, the value of the Trust's net assets shall be computed in the
manner specified in the Prospectus and the Trust's Declaration of Trust for the
computation of the value of the Trust's net assets in connection with the
determination of the net asset value of the Trust's shares. Payment of said
compensation shall be the sole responsibility of the Investment Adviser and
shall in no way be an obligation of the Fund or of the Trust.


                                      A-4


      8. Limitation of Liability. The Sub-Adviser shall not be liable for any
error of judgment or mistake of law or fact or for any loss suffered by the
Trust or the Investment Adviser in connection with the performance of this
Agreement, except a loss resulting from a breach of fiduciary duty with respect
to the receipt of compensation for services or a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Sub-Adviser in the
performance of its duties or from reckless disregard by it of its obligations
and duties under this Agreement.

      9. Duration and Termination. This Agreement will become effective as of
the date first written above, provided that it shall have been approved by vote
of a majority of the outstanding voting securities of the Fund, in accordance
with the requirements under the 1940 Act, and, unless sooner terminated as
provided herein, shall continue in effect until [Date no more than 2 years from
execution].

      Thereafter, if not terminated, this Agreement shall continue in effect for
successive periods of twelve months each ending on       of each year, provided
such continuance is specifically approved at least annually (a) by the vote of a
majority of those members of the Trust's Board of Trustees who are not parties
to this Agreement or interested persons of the Trust, the Sub-Adviser, or the
Investment Adviser, cast in person at a meeting called for the purpose of voting
on such approval, and (b) by the vote of a majority of the Trust's Board of
Trustees or by the vote of a majority of the outstanding voting securities of
the Fund. Notwithstanding the foregoing, this Agreement may be terminated at any
time on sixty days' written notice, without the payment of any penalty, by the
Trust (by vote of the Trust's Board of Trustees or by vote of a majority of the
outstanding voting securities of the Fund), by the Investment Adviser or by the
Sub-Adviser. This Agreement will immediately terminate in the event of its
assignment and upon termination of the Investment Advisory Agreement between the
Trust and the Investment Advisor. (As used in this Agreement, the terms
"majority of the outstanding voting securities," "interested persons" and
"assignment" shall have the same meaning of such terms in the 1940 Act.)

      10. Amendment of this Agreement. No provision of this Agreement may be
changed, waived, discharged or terminated orally, but only by an instrument in
writing signed by the party against which enforcement of the change, waiver,
discharge or termination is sought.

      11. Miscellaneous. The captions in this Agreement are included for
convenience of reference only and in no way define or delimit any of the
provisions hereof or otherwise affect their construction or effect.

      If any provision of this Agreement shall be held or made invalid by a
court decision, statute, rule or otherwise, the remainder of this Agreement
shall not be affected thereby.


                                      A-5


      This Agreement shall be binding upon and shall inure to the benefit of the

            disclosed by the Securities and Exchange Commission or any other
            regulatory examiner of the Sub-Adviser, any auditor of the parties
            hereto, by judicial or administrative process or otherwise by

            Sub-Adviser's ability to publish information regarding the
            performance of accounts under its management; and

            subsidiaries or affiliates of the Investment Adviser or Sub-Adviser.
            In dealing with such customers, the Sub-Adviser and its parent,
            subsidiaries, and affiliates will not inquire or take into
            consideration whether securities of those customers are held by the
            Trust.

      4. Services Not Exclusive. The investment advisory services furnished by
the Sub-Adviser hereunder are not to be deemed exclusive. Except to the extent
necessary to perform the Sub-Adviser's obligations under this Agreement, nothing
herein shall be deemed to limit or restrict the right of the Sub-Adviser, or any
subsidiary or affiliate of the Sub-Adviser, or any employee of the Sub-Adviser,
to engage in any other business, whether of a similar or dissimilar nature, or
to render services of any kind to any other person.

      5. Books and Records. In compliance with the requirements of Rule 3la-3
under the 1940 Act, the Sub-Adviser hereby agrees that all records which it
maintains for the Trust are the property of the Trust and further agrees to
surrender promptly to the Trust any of such records upon the Trust's request;
provided, however, that the Sub-Adviser may retain copies of any or all such
records. The Sub-Adviser further agrees to preserve for the periods prescribed
by Rule 3la-2 under the 1940 Act all records which it maintains for the Fund
that are required to be maintained by Rule 3la-2 under the 1940 Act.

      6. Expenses. During the term of this Agreement, the Sub-Adviser will pay
all expenses incurred by it in connection with its activities under this
Agreement other than the cost of securities (including brokerage commissions, if
any) purchased for the Trust. The Trust and the Investment Adviser will be
responsible for all of their respective expenses and liabilities.

      7. Compensation. For the services provided and the expenses assumed
pursuant to this Agreement, the Investment Adviser will pay the Sub-Adviser and
the Sub-Adviser will accept as full compensation therefor a fee computed daily
and paid monthly in arrears on the first business day of each month at an annual
rate of sixty one-hundredths of one percent (.60%) of the Portfolio's average
daily net assets. The Sub-Adviser agrees to waive a portion of the sub-advisory
fee equal to the percentage of the investment advisory fee waived by the
Investment Adviser under the Investment Advisory Agreement between the Trust and
the Investment Adviser.

      If the fee payable to the Sub-Adviser pursuant to this Section 7 begins to
accrue before the end of any month or if this Agreement terminates before the
end of any month, the fee for the period from such date to the end of such month
or from the


                                      B-4


beginning of such month to the date of termination, as the case may be, shall be
prorated according to the proportion which such period bears to the full month
in which such effectiveness or termination occurs. For purposes of calculating
fees, the value of the Portfolio's assets shall be computed in the manner
specified in the Prospectus and the Trust's Declaration of Trust for the
computation of the value of the Trust's net assets in connection with the
determination of the net asset value of the Trust's shares. Payment of said
compensation shall be the sole responsibility of the Investment Adviser and
shall in no way be an obligation of the Fund or of the Trust.

      8. Limitation of Liability. The Sub-Adviser shall not be liable for any
error of judgment or mistake of law or fact or for any loss suffered by the
Trust or the Investment Adviser in connection with the performance of this
Agreement, except a loss resulting from a breach of fiduciary duty with respect
to the receipt of compensation for services or a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Sub-Adviser in the
performance of its duties or from reckless disregard by it of its obligations
and duties under this Agreement.

      9. Duration and Termination. This Agreement will become effective as of
the date first written above, provided that it shall have been approved by vote
of a majority of the outstanding voting securities of the Fund, in accordance
with the requirements under the 1940 Act, and, unless sooner terminated as
provided herein, shall continue in effect until [Date no more than 2 years from
execution]. Thereafter, if not terminated, this Agreement shall continue in
effect for successive periods of twelve months each ending on of each year,
provided such continuance is specifically approved at least annually (a) by the
vote of a majority of those members of the Trust's Board of Trustees who are not
parties to this Agreement or interested persons of the Trust, the Sub-Adviser,
or the Investment Adviser, cast in person at a meeting called for the purpose of
voting on such approval, and (b) by the vote of a majority of the Trust's Board
of Trustees or by the vote of a majority of the outstanding voting securities of
the Fund. Notwithstanding the foregoing, this Agreement may be terminated at any
time on sixty days' written notice, without the payment of any penalty, by the
Trust (by vote of the Trust's Board of Trustees or by vote of a majority of the
outstanding voting securities of the Fund), by the Investment Adviser or by the
Sub-Adviser. This Agreement will immediately terminate in the event of its
assignment and upon termination of the Investment Advisory Agreement between the
Trust and the Investment Adviser. (As used in this Agreement, the terms
"majority of the outstanding voting securities," "interested persons" and
"assignment" shall have the same meaning of such terms in the 1940 Act.)

      10. Amendment of this Agreement. No provision of this Agreement may be
changed, waived, discharged or terminated orally, but only by an instrument in
writing signed by the party against which enforcement of the change, waiver,
discharge or termination is sought.

shall not be affected thereby.

parties hereto and their respective successors and shall be governed by the laws
of the Commonwealth of Massachusetts.

to the assets of the Trust belonging to such series for the enforcement of any
claims against the Trust.
