                              SUBADVISORY AGREEMENT

     THIS AGREEMENT is made and entered into as of the 1st day of October, 2007,
by and among NATIONWIDE MUTUAL FUNDS (the "Trust),  a Delaware  statutory trust,
NATIONWIDE FUND ADVISORS (the "Adviser"),  a Delaware statutory trust registered
under the Investment  Advisers Act of 1940, as amended (the "Advisers Act"), and
ABERDEEN  ASSET  MANAGEMENT  INC.,  a  corporation  organized  under the laws of
Delaware (the "Subadviser"), and also registered under the Advisers Act.

                                   WITNESSETH:

     WHEREAS,  the Trust is  registered  with the U.S.  Securities  and Exchange
Commission (the "SEC") as an open-end  management  investment  company under the
Investment Company Act of 1940, as amended (the "1940 Act");

     WHEREAS, the Adviser has, pursuant to an Investment Advisory Agreement with
the Trust dated as of the 1st day of May, 2007 (the "Advisory Agreement"),  been
retained  to act as  investment  adviser  for certain of the series of the Trust
that are listed on Exhibit A to this Agreement (each, a "Fund");

     WHEREAS,  the Adviser  represents  that it is willing and  possesses  legal
authority to render such services  subject to the terms and conditions set forth
in this Agreement;

     WHEREAS,  the  Trust  and the  Adviser  each  represent  that the  Advisory
Agreement  permits  the  Adviser to  delegate  certain  of its duties  under the
Advisory Agreement to other investment advisers,  subject to the requirements of
the 1940 Act; and

     WHEREAS,  the Adviser  desires to retain the Subadviser to assist it in the
provision  of a  continuous  investment  program for that  portion of the Funds'
assets that the Adviser will assign to the  Subadviser,  and the  Subadviser  is
willing to render such services subject to the terms and conditions set forth in
this Agreement,

     NOW,  THEREFORE,  the parties do mutually agree and promise as follows with
respect to each Fund:

     1. Appointment as Subadviser. The Adviser hereby appoints the Subadviser to
act as investment adviser for and to manage that portion or all of the assets of
the  Funds  that the  Adviser  from time to time upon  reasonable  prior  notice
allocates  to, and puts under the control of, the  Subadviser  (the  "Subadviser
Assets")  subject to the supervision of the Adviser and the Board of Trustees of
the Trust and subject to the terms of this Agreement;  and the Subadviser hereby
accepts such appointment.  In such capacity, the Subadviser shall be responsible
for the investment  management of the Subadviser  Assets.  It is recognized that
the Subadviser and certain of its affiliates now act, and that from time to time
hereafter  may  act,  as  investment  adviser  to one or more  other  investment
companies  and to fiduciary or other  managed  accounts and that the Adviser and
the Trust cannot object to such activities.

     2. Duties of Subadviser.

          a.  Investments.  The Subadviser is hereby authorized and directed and
     hereby agrees,  subject to the stated investment  policies and restrictions
     of a Fund as set forth in a Fund's  prospectus  and statement of additional
     information  as  currently  in effect and, as soon as  practical  after the
     Trust,  a  Fund  or  the  Adviser  notifies  the  Subadviser   thereof,  as
     supplemented  or  amended  from  time to  time  (collectively  referred  to
     hereinafter  as the  "Prospectus")  and  subject to the  directions  of the
     Adviser and the Trust's Board of Trustees, to monitor on a continuous basis
     the  performance  of the  Subadviser  Assets  and to  conduct a  continuous
     program  of  investment,   evaluation   and,  if   appropriate,   sale  and
     reinvestment  of the Subadviser  Assets.  The Adviser agrees to provide the
     Subadviser  with such  assistance  as may be  reasonably  requested  by the
     Subadviser  in  connection  with the  Subadviser's  activities  under  this
     Agreement, including, without limitation,  providing information concerning
     a Fund, its funds  available,  or to become  available,  for investment and
     generally as to the conditions of such Fund's or the Trust's affairs.

          b. Compliance with  Applicable  Laws and Governing  Documents.  In the
     performance of its services under this Agreement,  the Subadviser shall act
     in conformity with the Prospectus and the Trust's Agreement and Declaration
     of Trust and By-Laws as currently in effect and, as soon as practical after
     the Trust,  a Fund or the  Adviser  notifies  the  Subadviser  thereof,  as
     supplemented,  amended  and/or  restated  from  time to time  (referred  to
     hereinafter as the "Declaration of Trust" and "By-Laws,"  respectively) and
     with the instructions  and directions  received in writing from the Adviser
     or the  Trustees  of the Trust and will  conform to, and comply  with,  the
     requirements of the 1940 Act, the Internal Revenue Code of 1986, as amended
     (the  "Code"),  and  all  other  applicable  federal  and  state  laws  and
     regulations.  Without limiting the preceding sentence, the Adviser promptly
     shall  notify the  Subadviser  as to any act or omission of the  Subadviser
     hereunder  that the Adviser  reasonably  deems to  constitute  or to be the
     basis  of any  noncompliance  or  nonconformance  with  any of the  Trust's
     Declaration of Trust and By-Laws and the Prospectus,  the  instructions and
     directions  received  in writing  from the  Adviser or the  Trustees of the
     Trust or the 1940 Act, the Code, and all other applicable federal and state
     laws and  regulations.  Notwithstanding  the  foregoing,  the Adviser shall
     remain responsible for ensuring a Fund's and the Trust's overall compliance
     with the 1940 Act, the Code and all other applicable federal and state laws
     and  regulations  and the  Subadviser is only obligated to comply with this
     subsection  (b) with respect to the Subadviser  Assets.  The Adviser timely
     will provide the  Subadviser  with a copy of the minutes of the meetings of
     the Board of  Trustees of the Trust to the extent they may affect a Fund or
     the  services of the  Subadviser,  copies of any  financial  statements  or
     reports made by a Fund to its  shareholders,  and any further  materials or
     information  which the Subadviser  may  reasonably  request to enable it to
     perform its functions under this Agreement.

          The Adviser shall perform quarterly and annual tax compliance tests to
     ensure that a Fund is in compliance with Subchapter M and Section 817(h) of
     the Code.  In  connection  with such  compliance  tests,  the Adviser shall
     inform the  Subadviser  at least ten (10) business days prior to a calendar
     quarter  end if the  Subadviser  Assets  are  out of  compliance  with  the
     diversification  requirements  under either Subchapter M or Section 817(h).
     If the Adviser  notifies the Subadviser that the Subadviser  Assets are not
     in compliance with such requirements  noted above, the Subadviser will take
     prompt action to bring the Subadviser  Assets back into  compliance  within
     the time permitted under the Code thereunder.

          The Adviser will provide the Subadviser with reasonable advance notice
     of any change in a Fund's investment objectives,  policies and restrictions
     as stated in the Prospectus,  and the Subadviser  shall, in the performance
     of its duties and obligations  under this Agreement,  manage the Subadviser
     Assets  consistent  with such  changes,  provided that the  Subadviser  has
     received prompt notice of the  effectiveness of such changes from the Trust
     or the Adviser.  In addition to such notice,  the Adviser  shall provide to
     the Subadviser a copy of a modified Prospectus reflecting such changes. The
     Adviser  acknowledges and will ensure that the Prospectus will at all times
     be in compliance  with all  disclosure  requirements  under all  applicable
     federal  and state laws and  regulations  relating  to the Trust or a Fund,
     including,  without limitation, the 1940 Act, and the rules and regulations
     thereunder,  and that the Subadviser  shall have no liability in connection
     therewith,  except as to the accuracy of material information  furnished in
     writing by the Subadviser to the Trust or to the Adviser  specifically  for
     inclusion in the Prospectus. The Subadviser hereby agrees to provide to the
     Adviser in a timely manner such information  relating to the Subadviser and
     its  relationship  to, and actions  for, the Trust as may be required to be
     contained in the  Prospectus  or in the Trust's  Registration  Statement on
     Form N-1A.

          c. Voting of Proxies.  The Adviser hereby  delegates to the Subadviser
     the  Adviser's  discretionary  authority  to  exercise  voting  rights with
     respect to the  securities and other  investments in the Subadviser  Assets
     and  authorizes  the  Subadviser  to delegate  further  such  discretionary
     authority to a designee  identified  in a notice given to the Trust and the
     Adviser. The Subadviser,  including without limitation its designee,  shall
     have the power to vote,  either in person or by proxy,  all  securities  in
     which the  Subadviser  Assets may be invested from time to time,  and shall
     not be required to seek or take instructions from, the Adviser, the Fund or
     the Trust or take any action with respect  thereto.  If both the Subadviser
     and another  entity  managing  assets of a Fund have  invested  such Fund's
     assets in the same security, the Subadviser and such other entity will each
     have the power to vote its pro rata share of such Fund's security.

          The Subadviser will establish a written  procedure for proxy voting in
     compliance with current applicable rules and regulations, including but not
     limited to Rule 30b1-4 under the 1940 Act. The Subadviser  will provide the
     Adviser or its designee,  a copy of such  procedure and establish a process
     for the timely  distribution of the Subadviser's voting record with respect
     to a Fund's  securities  and other  information  necessary for such Fund to
     complete  information  required  by Form  N-1A  under  the 1940 Act and the
     Securities Act of 1933, as amended (the "Securities  Act"), Form N-PX under
     the 1940 Act,  and Form  N-CSR  under the  Sarbanes-Oxley  Act of 2002,  as
     amended, respectively.

          d. Agent.  Subject to any other written instructions of the Adviser or
     the Trust, the Subadviser is hereby appointed the Adviser's and the Trust's
     agent and  attorney-in-fact  for the limited purposes of executing  account
     documentation,  agreements, contracts and other documents as the Subadviser
     shall be requested by brokers, dealers, counterparties and other persons in
     connection  with its  management of the Subadviser  Assets.  The Subadviser
     agrees  to  provide  the  Adviser  and the  Trust  with  copies of any such
     agreements executed on behalf of the Adviser or the Trust.

          e. Brokerage. The Subadviser is authorized, subject to the supervision
     of the Adviser and the plenary  authority of the Trust's Board of Trustees,
     to  establish  and  maintain  accounts on behalf of a Fund with,  and place
     orders for the investment and reinvestment,  including  without  limitation
     purchase and sale, of the Subadviser Assets with or through,  such persons,
     brokers  (including,  to the extent permitted by applicable law, any broker
     affiliated  with the  Subadviser)  or dealers  (collectively  "Brokers") as
     Subadviser  may  elect  and  negotiate  commissions  to  be  paid  on  such
     transactions.  The  Subadviser,  however,  is not  required  to obtain  the
     consent  of  the  Adviser  or  the  Trust's  Board  of  Trustees  prior  to
     establishing  any such brokerage  account.  The Subadviser  shall place all
     orders for the  purchase  and sale of  portfolio  investments  for a Fund's
     account with Brokers  selected by the Subadviser.  In the selection of such
     Brokers and the placing of such orders, the Subadviser shall seek to obtain
     best  execution  for a Fund.  The  Subadviser  is  permitted  to pay higher
     brokerage  commissions  for  brokerage and research  services,  as provided
     below. In using its reasonable efforts to obtain best execution for a Fund,
     the  Subadviser,  bearing  in mind the best  interests  of each Fund at all
     times,  shall consider all factors it deems relevant,  including price, the
     size of the  transaction,  the  breadth  and  nature of the  market for the
     security, the difficulty of the execution, the amount of the commission, if
     any,  the  timing  of  the  transaction,  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.
     Notwithstanding  the  foregoing,  neither the Trust, a Fund nor the Adviser
     shall instruct the Subadviser to place orders with any particular Broker(s)
     with  respect to the  Subadviser  Assets.  Subject to such  policies as the
     Trustees may determine,  or as may be mutually agreed to by the Adviser and
     the  Subadviser,  the  Subadviser is authorized but not obligated to cause,
     and 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  (within the meaning of Section 28(e) of the  Securities  Exchange
     Act of 1934) to the  Subadviser  an amount of  commission  for  effecting a
     Subadviser Assets'  investment  transaction that is in excess of the amount
     of commission  that another  Broker would have charged for  effecting  that
     transaction  if, but only if, the Subadviser  determines in good faith that
     such  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 overall responsibility of the Subadviser
     with  respect  to  the  accounts  as  to  which  it  exercises   investment
     discretion.

          It is  recognized  that the  services  provided by such Brokers may be
     useful to the Subadviser in connection  with the  Subadviser's  services to
     other clients.  On occasions when the Subadviser deems the purchase or sale
     of a security  to be in the best  interests  of a Fund with  respect to the
     Subadviser  Assets  as  well  as  other  clients  of  the  Subadviser,  the
     Subadviser,  to the extent  permitted by applicable  laws and  regulations,
     may, but shall be under no obligation  to,  aggregate the  securities to be
     sold or  purchased  in order to obtain  the most  favorable  price or lower
     brokerage commissions and efficient execution. In such event, allocation of
     securities  so sold or purchased,  as well as the expenses  incurred in the
     transaction,  will be made by the  Subadviser in the manner the  Subadviser
     considers  to be the most  equitable  and  consistent  with  its  fiduciary
     obligations to each Fund and to such other clients.  It is recognized  that
     in some  cases,  this  procedure  may  adversely  affect  the price paid or
     received by a Fund or the size of the position  obtainable for, or disposed
     of by, such Fund with respect to the Subadviser Assets.

          f. Securities  Transactions.  The Subadviser and any affiliated person
     of the Subadviser will not purchase securities or other instruments from or
     sell  securities or other  instruments to a Fund;  provided,  however,  the
     Subadviser  or  any  affiliated  person  of  the  Subadviser  may  purchase
     securities  or  other   instruments   from  or  sell  securities  or  other
     instruments to a Fund if such  transaction is permissible  under applicable
     laws and regulations,  including,  without limitation, the 1940 Act and the
     Advisers Act and the rules and regulations promulgated thereunder.


          The  Subadviser,  on its own  behalf  and with  respect  to its Access
     Persons  (as defined in  subsection  (e) of Rule 17j-1 under the 1940 Act),
     agrees to observe and comply with Rule 17j-1 and its Code of Ethics  (which
     shall comply in all material  respects with Rule 17j-1), as the same may be
     amended from time to time. On at least an annual basis, the Subadviser will
     comply with the  reporting  requirements  of Rule 17j-1,  which may include
     either (i)  certifying  to the Adviser that the  Subadviser  and its Access
     Persons have complied with the Subadviser's  Code of Ethics with respect to
     the  Subadviser  Assets  or (ii)  identifying  any  violations  which  have
     occurred with respect to the Subadviser  Assets.  The Subadviser  will have
     also submitted its Code of Ethics for its initial  approval by the Board of
     Trustees  no  later  than  the  date of  execution  of this  agreement  and
     subsequently within six months of any material change thereto.

          g. Books and Records.  The Subadviser shall maintain separate detailed
     records as are required by applicable  laws and  regulations of all matters
     hereunder  pertaining  to the  Subadviser  Assets (the  "Fund's  Records"),
     including,   without  limitation,   brokerage  and  other  records  of  all
     securities transactions.  The Subadviser acknowledges that a Fund's Records
     are  property  of the Trust;  except to the extent that the  Subadviser  is
     required  to  maintain a Fund's  Records  under the  Advisers  Act or other
     applicable  law and except  that the  Subadviser,  at its own  expense,  is
     entitled  to make  and  keep a copy of a Fund's  Records  for its  internal
     files.  A Fund's  Records shall be available to the Adviser or the Trust at
     any time upon reasonable  request during normal business hours and shall be
     available for telecopying  promptly to the Adviser during any day that such
     Fund is open for business as set forth in the Prospectus.

          h. Information Concerning Subadviser Assets and Subadviser.  From time
     to time as the Adviser or the Trust  reasonably  may request in good faith,
     the  Subadviser  will  furnish the  requesting  party  reports on portfolio
     transactions and reports on the Subadviser  Assets,  all in such reasonable
     detail as the parties may  reasonably  agree in good faith.  The Subadviser
     will also  inform the  Adviser in a timely  manner of  material  changes in
     portfolio  managers  responsible for Subadviser  Assets, any changes in the
     ownership or management of the  Subadviser,  or of material  changes in the
     control of the  Subadviser.  Upon the Trust's or the  Adviser's  reasonable
     request,  the Subadviser  will make available its officers and employees to
     meet with the Trust's Board of Trustees to review the Subadviser Assets via
     telephone on a quarterly  basis and on a less frequent basis as agreed upon
     by the parties in person.

          Subject to the other provisions of this Agreement, the Subadviser will
     also provide such  information or perform such additional acts with respect
     to the Subadviser  Assets as are  reasonably  required for the Trust or the
     Adviser to comply with their respective  obligations under applicable laws,
     including without limitation, the Code, the 1940 Act, the Advisers Act, and
     the  Securities  Act,  and any rule or  regulation  thereunder.

          i.  Custody  Arrangements.  The Trust or the Adviser  shall notify the
     Subadviser  of the  identities  of its  custodian  banks  and  the  custody
     arrangements therewith with respect to the Subadviser Assets and shall give
     the Subadviser  written  notice of any changes in such  custodian  banks or
     custody arrangements. The Subadviser shall on each business day provide the
     Adviser and the Trust's  custodian such  information as the Adviser and the
     Trust's  custodian  may  reasonably  request in good faith  relating to all
     transactions concerning the Subadviser Assets. The Trust shall instruct its
     custodian  banks to (A) carry  out all  investment  instructions  as may be
     directed by the  Subadviser  with respect to the  Subadviser  Assets (which
     instructions may be orally given if confirmed in writing);  and (B) provide
     the  Subadviser  with  all  operational   information   necessary  for  the
     Subadviser  to  trade  the  Subadviser  Assets  on  behalf  of a Fund.  The
     Subadviser  shall  have no  liability  for the  acts  or  omissions  of the
     authorized  custodian(s),  unless  such act or  omission is required by and
     taken in reliance upon instructions given to the authorized custodian(s) by
     a representative of the Subadviser properly authorized (pursuant to written
     instruction by the Adviser) to give such instructions.

     3. Independent  Contractor.  In the performance of its services  hereunder,
the  Subadviser is and shall be an independent  contractor and unless  otherwise
expressly  provided  herein or otherwise  authorized  in writing,  shall have no
authority to act for or represent the Fund,  the Trust or the Adviser in any way
or otherwise be deemed an agent of a Fund, the Trust or the Adviser.

     4. Expenses. During the term of this Agreement, the Subadviser will pay all
expenses  incurred by it in connection with its activities under this Agreement.
The Subadviser shall, at its sole expense,  employ or associate itself with such
persons as it believes to be  particularly  fitted to assist it in the execution
of its duties under this Agreement.  The Subadviser shall not be responsible for
the Trust's,  a Fund's or Adviser's  expenses,  which shall include,  but not be
limited to, the cost of securities, commodities and other investments (including
brokerage  commissions and other  transaction  charges,  if any) purchased for a
Fund and any losses  incurred in  connection  therewith,  expenses of holding or
carrying Subadviser Assets, including, without limitation, expenses of dividends
on stock  borrowed  to cover a short sale and  interest,  fees or other  charges
incurred in connection with leverage and related  borrowings with respect to the
Subadviser Assets,  organizational and offering expenses (which include, but are
not limited to,  out-of-pocket  expenses,  but not overhead or employee costs of
the Subadviser); expenses for legal, accounting and auditing services; taxes and
governmental  fees; dues and expenses  incurred in connection with membership in
investment company organizations; costs of printing and distributing shareholder
reports, proxy materials,  prospectuses,  stock certificates and distribution of
dividends; charges of a Fund's custodians and sub-custodians, administrators and
sub-administrators,  registrars, transfer agents, dividend disbursing agents and
dividend  reinvestment plan agents;  payment for portfolio pricing services to a
pricing  agent,  if any;  registration  and filing fees of the SEC;  expenses of
registering or qualifying  securities of a Fund for sale in the various  states;
freight and other charges in connection with the shipment of a Fund's  portfolio
securities;   fees  and  expenses  of  non-interested   Trustees;   salaries  of
shareholder  relations  personnel;  costs of shareholders  meetings;  insurance;
interest;   brokerage   costs;   and  litigation  and  other   extraordinary  or
non-recurring  expenses.  The Trust or the  Adviser,  as the case may be,  shall
reimburse  the  Subadviser  for any  expenses of a Fund or the Adviser as may be
reasonably  incurred by such  Subadviser  on behalf of such Fund or the Adviser.
The  Subadviser  shall keep and supply to the Trust and the  Adviser  reasonable
records of all such expenses.

     5. Compensation.  For the services provided pursuant to this Agreement, the
Subadviser is entitled to the fee listed for the Funds on Exhibit A hereto. Such
fees will be computed  daily and paid no later than the seventh  (7th)  business
day following the end of each month,  from the Adviser,  calculated at an annual
rate based on the Subadviser Assets' average daily net assets.

The  method of  determining  the net asset  value of the  Subadviser  Assets for
purposes  hereof shall be the same as the method of determining  net asset value
for purposes of establishing  the offering and redemption price of the shares of
the Trust as  described in the Fund's  Prospectus.  If this  Agreement  shall be
effective  for only a portion of a month with respect to a Fund,  the  aforesaid
fee shall be prorated for the portion of such month during which this  Agreement
is in effect for such Fund.

     of the  Adviser  or any  other  subadviser  to a Fund with  respect  to the
     portion of the assets of that Fund not managed by Subadviser,  or (ii) acts
     of the Subadviser which result from acts of the Adviser, including, but not
     limited  to, a failure  of the  Adviser  to provide  accurate  and  current
     information  with respect to any records  maintained  by the Adviser or any
     other  subadviser to a Fund,  which  records are not also  maintained by or
     otherwise available to the Subadviser upon reasonable request.  The Adviser
