      AGREEMENT,  dated as of July 17, 2003,  by and between  OPTIMUM FUND TRUST
(the "Trust") and DELAWARE  MANAGEMENT  COMPANY, a series of Delaware Management
Business Trust (the "Investment Manager").
      WHEREAS,   the  Trust  is  an  investment  company  registered  under  the
Investment Company Act of 1940, as amended (the "1940 Act"), and is organized as
a statutory trust under the laws of the State of Delaware; and
      WHEREAS,  the Trust is and will continue to be a series fund having one or
more investment portfolios, each with its own investment objective, policies and
restrictions; and
      WHEREAS,  the Investment Manager is a registered  investment adviser under
the Investment Advisers Act of 1940, as amended (the "Advisers Act") and engages
in the business of providing investment advisory services; and
      WHEREAS,  the 1940 Act  prohibits  any person from acting as an investment
adviser  to a  registered  investment  company  except  pursuant  to  a  written
contract; and
      WHEREAS,  the Board of Trustees  (the  "Board" or the  "Trustees")  of the
Trust desires to retain the Investment  Manager as the investment manager of the
Trust;
      NOW,  THEREFORE,  the Trust and the  Investment  Manager  hereby  agree as
follows:
                    1. APPOINTMENT OF THE INVESTMENT MANAGER
      The Trust hereby appoints the Investment Manager as the investment manager
for each of the series of the Trust  specified in Appendix A to this  Agreement,
as such Appendix A may be amended by the  Investment  Manager and the Trust from
time to time (the  "Funds"),  subject to the  supervision of the Trustees of the
Trust and in the  manner  and under the terms and  conditions  set forth in this
Agreement.  The Investment Manager accepts such appointment and agrees to render
the  services  and to  assume  the  obligations  set  forth  in  this  Agreement
commencing on its effective date. The Investment  Manager will be an independent
contractor  and will have no authority to act for or represent  the Trust in any
way or  otherwise  be  deemed  an  agent  unless  expressly  authorized  in this
Agreement or another writing by the Trust and the Investment Manager.
                       2. DUTIES OF THE INVESTMENT MANAGER
      A. Subject to the general  supervision  and control of the Trustees of the
Trust and under the terms and conditions set forth in this Agreement,  the Trust
acknowledges  and agrees that it is  contemplated  that the  Investment  Manager
will,  at its own  expense,  select  and  contract  with one or more  investment
advisers ("Sub-Advisers") to manage the investment operations and composition of
each and every  Fund of the Trust and  render  investment  advice for each Fund,
including  the  purchase,   retention,   and  disposition  of  the  investments,
securities  and cash  contained  in each Fund,  in  accordance  with each Fund's
investment  objective,  policies  and  restrictions  as  stated  in the  Trust's
Agreement  and  Declaration  of Trust and By-Laws,  such Fund's  Prospectus  and
Statement of Additional  Information  ("SAI"), and any other written guidelines,
policies and  procedures  adopted by the Trust and  applicable  to such Fund, as
from time to time in effect;  provided,  that any contract with a Sub-Adviser (a
"Sub-Advisory  Agreement")  shall be in compliance with and approved as required
by the 1940 Act or in accordance with exemptive relief granted by the Securities
and Exchange Commission ("SEC") under the 1940 Act.
      B. Subject  always to the  supervision  and control of the Trustees of the
Trust, the Investment Manager will have (i) overall  supervisory  responsibility
for the general  management  and  investment  of each Fund's  assets;  (ii) full
discretion to select new or additional  Sub-Advisers  for each Fund;  (iii) full
discretion to enter into and materially modify existing Sub-Advisory  Agreements
with   Sub-Advisers;   (iv)  full   discretion  to  terminate  and  replace  any
Sub-Adviser;  and (v) full investment discretion to make all determinations with
respect to the  investment of a Fund's assets not then managed by a Sub-Adviser.
In  connection  with  the  Investment  Manager's  responsibilities  herein,  the
Investment  Manager  will assess each Fund's  investment  focus and will seek to
implement  decisions  with respect to the allocation  and  reallocation  of each
Fund's assets among one or more current or additional  Sub-Advisers from time to
time,  as the  Investment  Manager  deems  appropriate,  to enable  each Fund to
achieve its investment goals. In addition,  the Investment  Manager will monitor
the compliance of each Sub-Adviser with the investment objectives,  policies and
restrictions of any Fund or Funds (or portions of any Fund) under the management
of  such  Sub-Adviser,  and  the  compliance  of  each  Sub-Adviser  with  legal
regulatory   requirements  and  any  other  written  guidelines,   policies  and
procedures  adopted  by the Trust  and  applicable  to such  Fund or Funds.  The
Investment  Manager  will review and report to the Trustees of the Trust on such
compliance  of  each  Fund  and on the  performance  of  each  Sub-Adviser.  The
Investment  Manager will furnish,  or cause the  appropriate  Sub-Adviser(s)  to
furnish,  to  the  Trust  such  statistical  information,  with  respect  to the
investments  that a Fund (or  portions  of any  Fund)  may  hold or  contemplate
purchasing,  as the Trust may reasonably request and is reasonably available. On
the Investment Manager's own initiative, the Investment Manager will apprise, or
cause  the  appropriate  Sub-Adviser(s)  to  apprise,  the  Trust  of  important
developments  materially affecting each Fund (or any portion of a Fund that they
advise) and will furnish the Trust,  from time to time, with such information as
may be appropriate for this purpose.  Further,  the Investment Manager agrees to
furnish, or cause the appropriate  Sub-Adviser(s) to furnish, to the Trustees of
the Trust such  periodic  and special  reports as the  Trustees of the Trust may
reasonably request.
      C. The  Investment  Manager  will also  furnish to the  Trust,  at its own
expense and without remuneration from or other cost to the Trust, the following:
         (i) OFFICE SPACE.  The Investment  Manager will provide office space in
the  offices  of  the  Investment  Manager  or in  such  other  place  as may be
reasonably  agreed  upon  by the  parties  hereto  from  time to  time,  and all
necessary office facilities and equipment;
         (ii) PERSONNEL. The Investment Manager will provide necessary executive
and other  personnel,  including  personnel for the  performance of clerical and
other office functions,  exclusive of those functions:  (a) related to and to be
performed under the Trust's contract or contracts for administration, custodial,
accounting,  bookkeeping, transfer, and dividend disbursing agency, distribution
or similar  services  by any entity,  including  the  Investment  Manager or its
affiliates,  selected to perform such  services  under such  contracts;  and (b)
related to the  services  to be  provided  by any  Sub-Adviser  pursuant  to any
Sub-Advisory Agreement; and
         (iii)  PREPARATION  OF PROSPECTUS AND OTHER  DOCUMENTS.  The Investment
Manager will cooperate in providing other  information and services,  other than
services  of outside  counsel  or  independent  accountants  or  services  to be
provided  by any  Sub-Adviser  under any  Sub-Advisory  Agreement,  required  in
connection with the preparation of all  registration  statements,  Prospectuses,
Prospectus supplements,  and SAIs, all annual,  semiannual, and periodic reports
to shareholders of the Trust, regulatory authorities, or others, all notices and
proxy  solicitation   materials  furnished  to  shareholders  of  the  Trust  or
regulatory authorities, and all tax returns.
      D. LIMITATIONS ON LIABILITY. The Investment Manager will exercise its best
judgment in rendering  its services to the Trust,  and the Trust  agrees,  as an
inducement  to the  Investment  Manager's  undertaking  to do so,  that,  in the
absence of willful misconduct, bad faith, gross negligence or reckless disregard
of its duties or obligations in rendering its services to the Trust as specified
in this  Agreement,  the Investment  Manager will not be liable for any error of
judgment  or  mistake  of law or for  any  loss  suffered  by the  Trust  or any
shareholder of the Trust in connection with the matters to which  this Agreement
                                       2
relates. Any person, even though an officer, director,  employee or agent of the
Investment Manager, who may be or become an officer,  Trustee, employee or agent
of the Trust,  shall be deemed,  when  rendering  services  to the Trust or when
acting on any business of the Trust,  to be rendering  such services to or to be
acting solely for the Trust and not as an officer, director,  employee or agent,
or one under the control or direction  of the  Investment  Manager,  even though
paid by it.
      E.  SECTION 11 OF THE  SECURITIES  EXCHANGE ACT OF 1934,  AS AMENDED.  The
Trust hereby  agrees that any entity or person  associated  with the  Investment
Manager  that is a member of a national  securities  exchange is  authorized  to
effect any  transaction on such exchange for the account of a Fund to the extent
and as permitted by Section  11(a)(1)(H) of the Securities Exchange Act of 1934,
as amended (the "1934 Act").
      F. SECTION 28(E) OF THE 1934 ACT. Subject to the appropriate  policies and
procedures approved by the Board of Trustees, the Investment Manager may, to the
extent authorized by Section 28(e) of the 1934 Act, cause a Fund to pay a broker
or dealer  that  provides  brokerage  or  research  services  to the  Investment
Manager,  a  Sub-Adviser,  the  Trust or the Fund an amount  of  commission  for
effecting  a Fund  transaction  in excess of the  amount of  commission  another
broker or dealer  would have  charged  for  effecting  that  transaction  if the
Investment Manager determines,  in good faith, that such amount of commission is
reasonable in relationship  to the value of such brokerage or research  services
provided in terms of that  particular  transaction or the  Investment  Manager's
overall  responsibilities  to  accounts  as  to  which  the  Investment  Manager
exercises investment discretion.  To the extent authorized by said Section 28(e)
and this  Agreement,  the  Investment  Manager shall not be deemed to have acted
unlawfully or to have  breached any duty created by this  Agreement or otherwise
solely  by  reason  of such  action.  In  addition,  subject  to  seeking  "best
execution" and in compliance with the Conduct Rules of the National  Association
of Securities  Dealers,  Inc., the Investment Manager may also consider sales of
shares of the Trust as a factor in the selection of brokers and dealers.
      G. DIRECTED BROKERAGE.  Subject to the requirement to seek best execution,
and to the direction by the Board of Trustees,  the Trust  reserves the right to
direct the Investment  Manager to cause  Sub-Advisers to effect  transactions in
Fund  securities  through  broker-dealers  in a manner  that will help  generate
resources to: (i) pay the cost of certain  expenses  which the Trust is required
to pay or for which the Trust is  required to arrange  payment  pursuant to this
Agreement;  or (ii) finance  activities that are primarily intended to result in
the sale of Trust  shares.  At the  discretion  of the Board of  Trustees,  such
resources  may be used to pay or cause the  payment of Trust  expenses or may be
used to finance  activities that are primarily intended to result in the sale of
Trust shares.

Investment  Manager of any expense of the Trust that the  Investment  Manager is
not  required  by  this  Agreement  to pay or  assume  shall  not  obligate  the
Investment Manager to pay or assume the same or any similar expense of the Trust

with respect to a particular  Fund, the fee for such Fund shall be pro-rated for
the portion of any month in which this  Agreement  is in effect with  respect to

                              5. NON-EXCLUSIVITY

rendering   services  to  any  other  person,   or  from  serving  as  officers,

regulations.
                           8. DURATION OF AGREEMENT
      This Agreement  shall become  effective upon the date first above written;
provided, however, that this Agreement shall not take effect unless it has first

outstanding  voting  securities of the Trust.  This Agreement  shall continue in
effect  for a period  more  than two (2) years  from the date of its  execution;

the outstanding voting securities of the Trust or, as appropriate, a majority of

voting securities" (as defined in Section 2(a)(42) of the ▇▇▇▇ ▇▇▇) of that Fund

Agreement  or its  continuance  may not have been  approved by a majority of the
outstanding voting securities of (a) any other Fund affected by the Agreement or
(b) all of the other Funds of the Trust.
      If the  shareholders  of any Fund fail to  approve  the  Agreement  or any

days pending the required  approval of the Agreement or its  continuance or of a
new contract with the Investment  Manager or a different  investment  manager or
other  definitive  action;  provided,  that  the  compensation  received  by the

than its actual costs incurred in furnishing  investment advisory and management
services to such Fund or the amount it would have  received  under the Agreement
in respect of such Fund, whichever is less.

other  organizational  document and agrees that the  obligations  assumed by the
Trust on behalf of a Fund  pursuant  to this  Agreement  shall be limited in all

accordance with the laws of the State of Delaware  (without giving effect to its

Act.  To the  extent  that the  laws of the  State  of  Delaware,  or any of the
provisions in this Agreement,  conflict with  applicable  provisions of the 1940
Act, the latter shall  control.  Any question of  interpretation  of any term or
provision of this Agreement having a counterpart in or otherwise  derived from a
term or provision of the 1940 Act shall be resolved by reference to such term or
provision of the 1940 Act and to interpretations  thereof, if any, by the United
