Dear Brion:

         The following is in response to our telephone conversation on December
30, 2004 regarding your additional comments on the filings and correspondence
referenced above.

Comment #1: Prospectus p.20 - "Right to reject or restrict purchase or exchange
- ----------
orders"

You asked that we provide a description of how the Funds propose to implement
the right to cancel purchases as related to the prospectus disclosure.

Response: Comment Accepted.
- --------

A description of how trades would be cancelled is as follows:

Trades received each day are processed nightly on the DST mainframe. During the
processing, DST applies systems edits to identify any trades that are not in
good order. Each morning, our market timing monitoring staff reviews trades
entered onto our systems the preceding night. Any trades that raise concerns
(e.g., unknown broker id number or broker number of a known market timer) are
raised, and, if necessary, researched prior to 11 a.m. If trades are identified
that are in violation of a Fund's market timing policy, they are "cancelled"
prior to 11 a.m., when all non-rejected trade data is then submitted to the
applicable custodian bank.

If you would like to discuss further, I can arrange for you to speak with an
individual who is familiar with the process.




Comment #2: SAI - Portfolio Dissemination Disclosure - Affiliated Persons
- ----------

With respect to the disclosure to Affiliated Persons, you asked that we be more
specific about the frequency of disclosure for two categories of Affiliated
Persons: (1) fund auditors and (2) Manulife and its affiliates.

Response: Comment Accepted.
- --------

We will revise the disclosure in question as follows:

     o    The fund's  certified  public  accounting  firm, as  identified  under
          "Independent  Registered  Public Accounting Firm" in this Statement of
          Additional  Information,  and its employees who provide audit or other
          services to the fund - provision of  information  on an annual  basis,
          such  information  being  provided  immediately  after  the end of the
          fund's fiscal year, in connection with the accounting  firm's audit of
          financial statements.
     o    Manulife,  its  affiliates and any of their  employees,  to the extent
          such   entities  or  persons  are  acting  in  a  legal,   accounting,
          compliance,  internal control or supervisory  capacity but only to the
          extent  that such  access is required  to enable  those  employees  to
          perform their assigned duties which do not conflict with the interests
          of the fund - provision of  information  is not on a scheduled  basis,
          but rather on an as-needed  basis to perform the functions  referenced
          above.

Please note that at this time it is hard for me to provide the typical frequency
of disclosure to Manulife or its affiliates. I will look into this further and
will attempt to make the language more specific in future filings.

If you have any additional questions or comments, please do not hesitate to
contact me at (617) 375-1722.

Sincerely,
