                 SECTION 2. AMENDMENTS TO SUBADVISER AGREEMENT
     2.1. Amendment to Section 1(a). Section 1(a) of the Subadviser Agreement is
hereby amended to read in its entirety as follows:
     (a)  Subject always to the control of the Manager (to the extent
          contemplated by this Agreement and the Management Contract described
          in Section 4 hereof) and the trustees of The Preferred Group of Mutual
          Funds (the "Trustees"), a Massachusetts business trust (the "Trust"),
          including the Manager's authority to determine what securities or
          other property shall be purchased or sold by or for the Preferred
          Large Cap Value Fund series of the Trust (the "Fund"), the Subadviser,
          at its expense, will furnish continuously an investment program for
          the Fund and will make investment decisions on behalf of the Fund and
          place all orders for the purchase and sale of portfolio securities and
          all other investments. In the performance of its duties, the
          Subadviser (i) will comply with the provisions of the Trust's
          Agreement and Declaration of Trust and By-laws, including any
          amendments thereto (upon receipt of such amendments by the
          Subadviser), and the investment objectives, policies and restrictions
          of the Fund as set forth in its current Prospectus and Statement of
          Additional Information (copies of which will be supplied to
          the Subadviser upon filing with the Securities and Exchange
          Commission), (ii) will use its best efforts to safeguard and promote
          the welfare of the Fund, (iii) will comply with other policies which
          the Trustees or the Manager, as the case may be, may from time to time
          determine as promptly as practicable after such policies have been
          communicated to the Subadviser in writing, and (iv) shall exercise the
          same care and diligence expected of the Trustees. The Subadviser and
          the Manager shall each make its officers and employees available to
          the other from time to time at reasonable times to review investment
          policies of the Fund and to consult with each other regarding the
          investment affairs of the Fund.
     2.2. Amendment to Section 1(c). Section 1(c) of the Subadviser Agreement is
hereby amended to read in its entirety as follows:
     (c)  In the selection of brokers, dealers or futures commissions merchants
          (collectively, "brokers") and the placing of orders for the purchase
          and sale of portfolio investments for the Fund, the Subadviser shall
          comply with such policies established by the Trustees or the Manager
          and communicated to the Subadviser in writing and shall seek to obtain
          for the Fund the most favorable price and execution available, except
          to the extent it may be permitted to pay higher brokerage commissions
          for brokerage and research services as described below. In using its
          best efforts to obtain for the Fund the most favorable price and
          execution available, the Subadviser, bearing in mind the Fund's best
          interests at all times, shall consider all factors it deems relevant,
          including, by way of illustration, price, the size of the transaction,
          the nature of the market for the security, the amount of the
          commission, the timing of the transaction taking into account 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. Subject to such policies as the Trustees
          or the Manager may determine and communicate to the Subadviser in
          writing, the Subadviser 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 to the Subadviser or any
          affiliated person of the Subadviser an amount of commission for
          effecting a portfolio investment transaction in excess of the amount
          of commission another broker would have charged for effecting that
          transaction, if the Subadviser determines in good faith that such
          amount of 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 Subadviser's
          overall responsibilities with respect to the Fund and to other clients
          of the Subadviser and any affiliated person of the Subadviser as to
          which the Subadviser or any affiliated person of the Subadviser
          exercises investment discretion. The Trust agrees that any entity or
          person associated with the Subadviser or any affiliated person of the
          Subadviser which is a member of a national securities exchange is
          authorized to effect any transaction on such exchange for the account
          of the Fund which is permitted by Section 11(a) of the Securities
          Exchange Act of 1934, as amended (the "1934 Act"), and Rule 11a2-2(T)
          thereunder, and the Trust hereby consents to the retention of
          compensation for such transactions in accordance with Rule
          11a2-2(T)(2)(iv).
                                      -2-
                           SECTION 3. MISCELLANEOUS.
     3.1. Continuing Effect. Except as expressly amended hereby, all of the
terms and provisions of the Subadviser Agreement are and shall remain in full
force and effect.
     3.2. Counterparts. This Amendment may be executed in any number of
counterparts by the parties hereto (including by facsimile transmission), each
of which counterparts when so executed shall be an original, but all the
counterparts shall together constitute one and the same instrument.
     3.3. Governing Law. This Amendment shall be governed by, and construed and
interpreted in accordance with, the laws governing the Subadviser Agreement.
            [The remainder of this page is intentionally left blank.]
     IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
executed and delivered by their respective duly authorized officers as of the
date first above written.
