         (4)  The Company's  Registration  Statement  under the 1940 Act and the

              its  shareholders  or  to  any  governmental  body  or  securities
              exchange.
         The Adviser shall furnish the Sub-Adviser  with any further  documents,

         and the Adviser  shall not use any such  materials  if the  Sub-Adviser
         reasonably objects in writing five business days (or such other time as
         may be mutually agreed) after receipt thereof. The Adviser shall ensure
         that  materials  prepared by  employees or agents of the Adviser or its
         affiliates  that refer to the Sub-Adviser or its clients in any way are
         consistent with those materials  previously approved by the Sub-Adviser
         as referenced in the preceding sentence.
5.   BROKERAGE.
     A.  The Sub-Adviser agrees that, in placing orders with  broker-dealers for
         the  purchase  or sale of  portfolio  securities,  it shall  attempt to
         obtain best execution at favorable  security prices;  provided that, on
         behalf of the Fund, the Sub-Adviser  may, in its  discretion,  agree to
         pay a broker-dealer  that furnishes  brokerage or research  services as
         such  services  are  defined  under  Section  28(e)  of the  Securities
         Exchange Act of 1934, as amended ("1934 Act"), a higher commission than
         that  which  might  have been  charged  by  another  broker-dealer  for
         effecting the same transactions,  if the Sub-Adviser determines in good
         faith that such  commission  is reasonable in relation to the brokerage
         and research services provided by the broker-dealer, viewed in terms of
         either that particular  transaction or the overall  responsibilities of
         the  Sub-Adviser  with respect to the accounts as to which it exercises
         investment  discretion (as such term is defined under Section  3(a)(35)
         of the 1934 Act). In no instance will portfolio securities be purchased
         from or sold  to the  Sub-Adviser,  or any  affiliated  person  thereof
         ("PRINCIPAL  TRANSACTIONS"),  except  in  accordance  with the  federal
         securities laws and the rules and regulations thereunder. Regardless of
         the  provisions  of the federal  securities  laws relating to Principal
         Transactions,  as  currently  in  effect  or as may be  amended  in the
         future,  no such transactions will be effected for the Fund without the
         express written authorization of the Adviser.
     B.  On  occasions  when the  Sub-Adviser  deems the  purchase  or sale of a
         security  to be in the  best  interest  of the  Fund as  well as  other
         clients of the Sub-Adviser, the Sub-Adviser, to the extent permitted by
         applicable laws and regulations,  may, but shall be under no obligation
         to,  aggregate  the  securities  to be  purchased or sold to attempt to
         obtain  a more  favorable  price  or lower  brokerage  commissions  and
         efficient  execution.  In such event,  allocation of the  securities so
         purchased or sold, as well as the expenses incurred in the transaction,
         will be made by the Sub-Adviser in the manner the Sub-Adviser considers
         to be the most equitable and consistent with its fiduciary  obligations
         to the Fund and to its other clients.
6.   OWNERSHIP OF RECORDS.  The Sub-Adviser shall maintain all books and records
     required to be maintained by the  Sub-Adviser  pursuant to the 1940 Act and
     the  rules  and   regulations   promulgated   thereunder  with  respect  to
     transactions on behalf of the Fund. In compliance with the  requirements of
     Rule 31a-3 under the 1940 Act, the  Sub-Adviser  hereby agrees (i) that all
     records  that it  maintains  for the Fund are the  property of the Company,
     (ii) to preserve  for the periods  prescribed  by Rule 31a-2 under the 1940
     Act any records that it maintains  for the Company and that are required to
     be  maintained  by Rule  31a-1  under  the 1940 Act,  and  (iii)  agrees to
     surrender  promptly to the Company any records  that it  maintains  for the
     Company upon request by the Company; provided, however, the Sub-Adviser may
     retain copies of such records.
7.   REPORTS.  The  Sub-Adviser  shall  furnish to the Board or the Adviser,  or
     both, as appropriate, such information,  reports, evaluation,  analyses and
     opinions as the Sub-Adviser  and the Board or the Adviser,  as appropriate,
     may mutually agree upon from time to time.
8.   SERVICES TO OTHERS CLIENTS. Nothing contained in this Agreement shall limit
     or restrict (i) the freedom of the  Sub-Adviser,  or any affiliated  person
     thereof,  to render  investment  management  and  corporate  administrative
     services to other  investment  companies,  to act as investment  manager or
     investment counselor to other persons, firms, or corporations, or to engage
     in any  other  business  activities,  or (ii) the  right  of any  director,
     officer,  or  employee  of the  Sub-Adviser,  who may  also be a  director,
     officer,  or employee of the Company, to engage in any other business or to
     devote his or her time and  attention  in part to the  management  or other
     aspects of any other business,  whether of a similar nature or a dissimilar
     nature, so long as the  Sub-Adviser's  services under this Agreement is not
     impaired thereby.
9.   SUB-ADVISER'S  USE OF THE SERVICES OF OTHERS.  The  Sub-Adviser may (at its
     cost  except as  contemplated  by  Paragraph  5 of the  Agreement)  employ,
     retain,  or otherwise  avail itself of the services or  facilities of other
     persons or  organizations  for the purpose of providing the  Sub-Adviser or
     the  Company  or Fund,  as  appropriate,  with such  statistical  and other
     factual  information,  such advice  regarding  economic factors and trends,
     such advice as to occasional  transactions in specific securities,  or such
     other  information,  advice,  or  assistance  as the  Sub-Adviser  may deem
     necessary,  appropriate, or convenient for the discharge of its obligations
     hereunder or otherwise  helpful to the Company or the Fund, as appropriate,
     or in the discharge of Sub-Adviser's overall  responsibilities with respect
     to the other  accounts that it serves as  investment  manager or counselor.
     However,  the  Sub-Adviser  shall not assign or delegate  any of its duties
     under this Agreement without the approval of the Advisor and the Board.

     of its  officers,  directors,  or  employees,  nor  any  person  performing
     executive, administrative, trading, or other functions for the Company, the
     Fund (at the direction or request of the Sub-Adviser) or the Sub-Adviser in
     connection with the Sub-Adviser's  discharge of its obligations  undertaken

     mistake or loss resulting  from willful  misfeasance,  bad faith,  or gross
     negligence in the performance of its or his duties on behalf of the Company
     or Fund or from reckless disregard by the Sub-Adviser or any such person of

SCHEDULE 1
                                  FEE SCHEDULE
For the services  provided and the expenses assumed by the Sub-Adviser under the
terms of the  Agreement,  the  Sub-Adviser  shall  receive a monthly  investment
management fee as set forth below:
Average Daily Net Assets of the Fund                 Compensation
The first $50 million                                   .50% plus
$50 million or more                                     .40%
The schedule above is subject,  however, to a minimum investment  management fee
of $100,000 over the first twelve months from the date of inception of the Fund.
Therefore,  if at the end of the twelfth month after inception of the investment
management  fee paid totals less than  $100,000,  then the Adviser  will pay any
such difference in a lump-sum to the  Sub-Adviser.  For purposes of Section 3 of
the Agreement,  the value of the net assets of the Fund shall be computed in the
same  manner at the end of the  business  day as the value of such net assets is
computed  in  connection  with the  determination  of the net asset value of the
Fund's shares as described in the Fund's  prospectus and statement of additional
information.
