                                  ADVISOR CLASS


SECTION 1. DISTRIBUTION FEES

a.   DISTRIBUTION  FEE. For  purposes of paying  costs and expenses  incurred in
     providing  the  services  set forth in  SECTION 2 below,  the series of the
     Issuer  identified  on SCHEDULE A (the  "Funds")  shall pay the  investment
     adviser  engaged  by the Funds  (the  "Advisor"),  as paying  agent for the
     Funds,  a fee equal to 25 basis  points  (0.25%)  per annum of the  average
     daily net assets of the shares of the Funds'  Advisor  Class of shares (the
     "Distribution Fee").

b.   APPLICABILITY  TO NEW FUNDS. If the Issuer desires to add additional  funds
     to the Plan,  whether  currently  existing or created in the future (a "New
     Fund"),  and the Issuer's  Board of Trustees (the "Board") has approved the
     Plan for such New Fund as in the  manner  set  forth in  SECTION  4 of this
     Plan, as well as by the then-sole  shareholder  of the Advisor Class shares
     of such New Fund (if  required by the  Investment  Company Act of 1940 (the
     "1940  Act") or rules  promulgated  under the 1940  Act),  this Plan may be
     amended to provide that such New Fund will become  subject to this Plan and
     will pay the Distribution  Fee set forth in SECTION 1(A) above,  unless the
     Board  specifies  otherwise.  After the  adoption of this Plan by the Board
     with  respect  to the  Advisor  Class of shares  of the New Fund,  the term
     "Funds"  under this Plan  shall  thereafter  be deemed to include  such New
     Fund.

c.   CALCULATION  AND  ASSESSMENT.  Distribution  Fees  under  this Plan will be
     calculated  and accrued daily by each Fund and paid to the Advisor  monthly
     or at such other intervals as the Issuer and the Advisor may agree.

SECTION 2. DISTRIBUTION SERVICES

The Advisor  shall use the  Distribution  Fee set forth in SECTION  1(A) of this
Plan to pay for  services  in  connection  with  any  activities  undertaken  or
expenses incurred by the distributor of the Funds' shares (the "Distributor") or
its affiliates  primarily intended to result in the sale of Advisor Class shares
of the Funds,  which  services  may  include,  but are not  limited  to, (A) the
payment of sales commissions, ongoing commissions and other payments to brokers,
dealers,  financial  institutions or others who sell Advisor Class shares of the
Funds  pursuant  to  Selling   Agreements;   (B)   compensation   to  registered
representatives  or other  employees  of  Distributor  who  engage in or support
distribution  of the Funds'  Advisor  Class  shares;  (C)  compensation  to, and
expenses  (including  overhead and  telephone  expenses)  of,  Distributor;  (D)
printing of prospectuses,  statements of additional  information and reports for
other than existing shareholders; (E) preparation,  printing and distribution of
sales literature and advertising  materials provided to the




Funds'  shareholders and prospective  shareholders;  (F) receiving and answering
correspondence   from   prospective    shareholders,    including   distributing
prospectuses, statements of additional information, and shareholder reports; (G)
provision of facilities to answer  questions from  prospective  investors  about
Fund shares;  (H) complying with federal and state securities laws pertaining to
the sale of Fund shares; (I) assisting investors in completing application forms
and  selecting  dividend  and other  account  options;  (J)  provision  of other
reasonable  assistance in connection with the  distribution of Fund shares;  (K)
organizing  and  conducting  of  sales  seminars  and  payments  in the  form of
transactional   compensation  or  promotional  incentives;  (L)  profit  on  the
foregoing;  and (M) such other distribution and service activities as the Issuer
determines may be paid for by the Issuer  pursuant to the terms of this Plan and
in accordance  with Rule 12b-1 of the 1940 Act;  provided that if the Securities
and Exchange  Commission  determines that any of the foregoing  services are not
permissible   under  Rule  12b-1,   any  payments  for  such   activities   will
automatically cease.

SECTION 3. INDIVIDUAL SHAREHOLDER SERVICES

The Advisor may engage third parties to provide individual  shareholder services
to the  shareholders  of  the  Advisor  Class  shares  ("Individual  Shareholder
Services"). The amount set forth in SECTION 1(A) of this Plan may be paid to the
Advisor  for  expenses  incurred by it as a result of these  arrangements.  Such
Individual  Shareholder  Services and related  expenses relate to activities for
which  service  fees may be paid as  contemplated  by the  Conduct  Rules of the
Financial Industry Regulatory Authority ("FINRA"),  and may include, but are not
limited to, (A)  individualized  and customized  investment  advisory  services,
including the consideration of shareholder  profiles and specific goals; (B) the
creation  of  investment  models  and  asset  allocation  models  for use by the
shareholder  in selecting  appropriate  Funds;  (C)  proprietary  research about
investment  choices  and the market in  general;  (D)  periodic  rebalancing  of
shareholder  accounts to ensure  compliance with the selected asset  allocation;
(E) consolidation of shareholder accounts in one place; and (F) other individual
services; provided that if FINRA determines that any of the foregoing activities
are not permissible, any payment for such activities will automatically cease.

SECTION 4. EFFECTIVENESS

This Plan has been approved by the vote of both (a) the Board and (b) a majority
of those members of the Board who are not "interested persons" as defined in the
1940 Act (the "Independent  Members"),  and initially became effective on August
1, 1997.

SECTION 5. TERM

This Plan will  continue  in full force and effect for a period of one year from
the date  hereof,  and for  successive  periods  of up to one  year  thereafter,
provided that each such  continuance is approved by a majority of (a) the Board,
and (b) the Independent Members.

SECTION 6. REPORTING REQUIREMENTS

The Advisor shall administer this Plan in accordance with Rule 12b-1 of the 1940
Act.  The Advisor  shall  provide to the  Issuer's  Board,  and the  Independent
Members will review and approve in exercise of their fiduciary  duties, at least
quarterly,  a written  report of the  amounts  expended  under  this Plan by the
Advisor  with  respect to the Advisor  Class  shares of each Fund and such other
information as may be required by the 1940 Act and Rule 12b-1 thereunder.


                                       2


SECTION 7. TERMINATION

This Plan may be  terminated  without  penalty  at any time with  respect to the
Advisor Class shares of any Fund by the vote of a majority of the Board,  by the
vote of a majority of the Independent  Members,  or by the vote of a majority of
the  outstanding  shares of the Advisor Class of that Fund.  Termination  of the
Plan with  respect to the Advisor  Class  shares of one Fund will not affect the
continued effectiveness of this Plan with respect to the Advisor Class shares of
any other Fund.

SECTION 8. AMENDMENTS TO THIS PLAN

This Plan may not be amended to increase materially the amount of compensation a
Fund is  authorized  to pay under  SECTION 1 hereof  unless  such  amendment  is
approved in the manner  provided for in SECTION 4 hereof,  and such amendment is
further  approved by a majority of the outstanding  shares of the Fund's Advisor
Class, and no other material  amendment to the Plan will be made unless approved
in the manner provided for approval and annual renewal in SECTION 4 hereof.

SECTION 9. RECORDKEEPING

The Issuer will preserve copies of this Plan (including any amendments  thereto)
and any related agreements and all reports made pursuant to SECTION 5 hereof for
a period of not less than six years  from the date of this  Plan,  the first two
years in an easily accessible place.

IN WITNESS WHEREOF, the Issuer has executed this Plan as of January 1, 2008.
