                                 Date: 3/30/06

Consistent with the services  provided by the Transfer Agent and with respect to
the ownership of shares in the Fund for which the Transfer  Agent  maintains the
applicable shareholder information, the Transfer Agent shall:

1.    Submit all new account and registration  maintenance  transactions through
      the Office of Foreign  Assets  Control  ("OFAC")  database  and such other
      lists or databases of trade  restricted  individuals or entities as may be
      required from time to time by applicable regulatory authorities.

2.    Submit special payee checks through the OFAC database.

3.    Review  redemption  transactions  that occur  within  thirty  (30) days of
      account establishment or maintenance.

4.    Review  wires sent  pursuant to banking  instructions  other than those on
      file with the Transfer Agent.

5.    Review accounts with small balances followed by large purchases.

6.    Review  accounts  with  frequent  activity  within a specified  date range
      followed by a large redemption.

7.    On a  daily  basis,  review  purchase  and  redemption  activity  per  tax
      identification  number  ("TIN")  within the Funds to determine if activity
      for that TIN exceeded the $100,000 threshold on any given day.

8.    Compare all new accounts and  registration  maintenance  through the Known
      Offenders database and notify the Fund of any match.

9.    Monitor  and  track  cash   equivalents   under   $10,000  for  a  rolling
      twelve-month  period  and file IRS Form  8300 and  issue  the  shareholder
      notices required by the IRS.

10.   Determine  when a suspicious  activity  report  ("SAR") should be filed as
      required by regulations  applicable to mutual funds;  prepare and file the
      SAR.  Provide  the Fund with a copy of the SAR  within a  reasonable  time
      after  filing;  notify the Fund if any further  communication  is received
      from U.S.  Department  of the Treasury or other law  enforcement  agencies
      regarding the SAR.

11.   Compare account information to any FinCEN request received by the Fund and
      provided to the  Transfer  Agent  pursuant  to Uniting  and  Strengthening
      America by Providing  Appropriate Tools Required to Intercept and Obstruct
      Terrorism Act of 2001 ("USA PATRIOT  Act") Sec.  314(a).  Provide the Fund
      with  documents/information  necessary  to respond to  requests  under USA
      PATRIOT Act Sec. 314(a) within required time frames.

                                  (continued)

12.   In  accordance  with  agreed  upon  procedures  between  the  Fund and the
      Transfer Agent,  utilize information provided to the Transfer Agent by the
      Fund to assist the Fund in performing its Customer  Identification Process
      by employing  additional  data bases in efforts to provide  missing and/or
      incorrect  information.  The Fund is responsible for reviewing information
      provided by the Transfer Agent and updating the accounts.

In the  event  that the  Transfer  Agent  detects  activity  as a result  of the
foregoing  procedures,  which necessitates the filing by the Transfer Agent of a
SAR, a Form 8300 or other similar  report or notice to OFAC or other  regulatory
agency,  then the Transfer Agent shall also  immediately  notify the Fund unless
prohibited by applicable Law.
