Ott (Chairman), Mr. Condron, Ms. Davis, Ms. Hargadon, Mr. Holmes and Ms. Warner
comprise the Committee. The Committee separately reviews and makes

affiliates. During the fiscal year ended December 31, 2001, the Committee had
one meeting relating to the Trust.

The Trust's Audit Committee is composed entirely of Trustees who are not
interested persons of the Trust, AFC or its affiliates. Currently, Mr. Holmes
(Chairman), Mr. Condron, Ms. Davis and Dr. Ott comprise the Committee. This
Committee reviews and evaluates the audit function, including recommending to
the Board the independent accountants to be selected for the Trust, reviewing
all auditing procedures and arrangements and reviewing qualifications of key
personnel performing audit work. During the fiscal year ended December 31,
2001, the Committee had two meetings.

The Trust's Investment Operations Committee is composed of three Trustees
who are not interested persons of the Trust, AFC or its affiliates; two
Trustees who are interested persons and one non-Trustee participant. Currently,
Mr. Kavanaugh (Chairman), Ms. Hargadon, Mr. Harris, Mr. Reilly and Ms. Warner
are the Trustees who serve on the Committee. The non-Trustee participant is

not interested persons of the Trust, AFC or its affiliates. Currently Ms.
Warner (Chairman), Ms. Hargadon and Mr. Harris comprise the Committee. The
Committee is charged with the duties of reviewing the composition and
compensation of the Trustees, proposing additional non-interested Trustees for
election to the Board and reviewing major personnel changes of the Trust.
During the fiscal year ended December 31, 2001, the Committee had four
meetings. The Governance Committee will consider nominees recommended by
Shareholders. Recommendations should be submitted to the Committee in care of
the Secretary of the Trust.

If any of the nominees for election as Trustees shall by reason of death or
for any other reason become unavailable as a candidate at the Meeting, votes
pursuant to the enclosed proxy will be cast for a substitute candidate in the
discretion of the persons named as proxies therein, or their substitutes,
present and acting at the Meeting, or the Trustees may reduce the size of the
Board.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 and Section 30(h) of
the 1940 Act require the Trust's Trustees and officers, its investment adviser
and certain affiliated persons of the investment adviser and persons who own
more than ten percent of the Trust's shares to file reports of initial
ownership and changes in ownership with the Securities and Exchange Commission
("SEC") and the New York Stock Exchange. These individuals are required by SEC
regulations to furnish the Trust with copies of all Section 16(a) forms they
file.

To the Trust's knowledge, based solely on review of the copies of such
reports furnished to the Trust and written representations that no other
reports were required, all Section 16(a) filing requirements applicable to its
officers, Trustees, greater than ten percent beneficial owners and other
persons subject to Section 16(a) reporting were complied with during the fiscal
year ended December 31, 2001.

Recommended Shareholder Action and Required Vote

The Trustees recommend that the Shareholders vote for each nominee. A
plurality of the votes properly cast in person or by proxy at the Meeting is
required for the election of the Trustees.

2. OTHER MATTERS AND DISCRETION OF PERSONS NAMED AS PROXIES

While the Meeting is called to act upon any business that may properly come
before it, at the date of this Proxy Statement the only business which
management intends to present or knows that others will present is the business
mentioned in the Notice of the Meeting. If any other matters lawfully come
before the Meeting, and on all procedural matters at said Meeting, it is
intended that the enclosed proxy shall be voted in accordance with the best
judgment of the persons named as proxies therein, or their substitutes, present
and acting at the Meeting. A proxy may confer discretionary authority to vote
on matters brought before an annual meeting of shareholders if the Trust did
not have notice of the matter at least 45 days before the date on which the
Trust first mailed its proxy materials for the prior year's annual meeting of
shareholders (or date specified by an advance notice provision).

Date for Receipt of Shareholder Proposals

No proposals were submitted by Shareholders for presentation at the Meeting.
Shareholder proposals which are intended to be presented at the Annual Meeting
in 2003 must be received at the principal executive offices of the Trust, 440
Lincoln Street, Worcester, MA 01653, on or before November 1, 2002, for
inclusion in the proxy statement and proxy related to such meeting.

The following table lists the executive officers of the Trust, each of whom
is an employee of AFC or its affiliates:

Paul T. Kane (45)......... Assistant Vice President and Treasurer 1999

Mr. Kane was Vice President/Treasurer of Tax & Financial Services, BISYS Fund

Quorum and Method of Tabulation

Thirty percent (30%) of the shares entitled to vote, present in person or
represented by proxy, constitute a quorum for the transaction of business at
the Meeting. Votes cast by proxy or in person at the Meeting will be counted by
persons appointed by the Trust to act as tellers for the Meeting.

The tellers will count the total number of votes cast "for" approval of the
proposals for purposes of determining whether sufficient affirmative votes have
been cast. The tellers will count shares represented by proxies that withhold
authority to vote for a nominee for election as a Trustee or that reflect
abstentions or "broker nonvotes" (i.e., shares held by brokers or nominees as
to which (i) instructions have not been received from the beneficial owners or
persons entitled to vote and (ii) the broker or nominee does not have the
discretionary voting power on a particular matter) as shares that are present
and entitled to vote on the matter for purposes of determining the presence of
a quorum. With respect to the election of Trustees, neither withholding
authority to vote nor abstentions nor broker nonvotes have any effect on the
outcome of the voting on the matter.
