     and for performing the administrative functions herein set forth; (b)
     arranging, if desired by the Trust, for Directors, officers and employees
     of the Administrator to serve as Trustees, officers or agents of the Fund
     if duly elected or appointed to such positions and subject to their
     individual consent and to any limitations imposed by law; (c) preparing
     and, if applicable, filing all documents required for compliance by the
     Fund with applicable laws and regulations, including registration
     statements, registration fee filings, semi-annual and annual reports to

     Administrator shall not be deemed to have assumed or have any
     responsibility with respect to functions specifically assumed by any
     transfer agent or custodian of the Fund.

2.   The Administrator shall be free to render similar services to others so
     long as its services hereunder are not impaired thereby.

4.   This Agreement shall become effective as of the date of its execution, and

     by the Administrator, in each case on sixty days' written notice to the
     other party.

5.   This Agreement may be amended only by a writing signed by both parties.



6.   In the absence of willful misfeasance, bad faith or gross negligence on the
     part of the Administrator, or reckless disregard of its obligations and
     duties hereunder, the Administrator shall not be subject to any liability
     to the Trust or Fund, to any shareholder of the Trust or the Fund or to any
     other person, firm or organization, for any act or omission in the course
     of, or connected with, rendering services hereunder.
