agreements, and certain matters where there may be a possible conflict of
interest between the interests of the Trust and AFC or its affiliates. During

relating to the Trust.

The Trust's Audit Committee is composed entirely of Trustees who are not

the Board the independent accountants to be selected for the Trust, reviewing
all auditing procedures and arrangements and reviewing qualifications of key

2000, 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. Langton, Mr. Reilly and

The Trust's Governance Committee (formerly the Nominating Committee) is
composed entirely of Trustees who are not interested persons of the Trust, AFC
or its affiliates. Currently Ms. Warner (Chairman), Ms. Hargadon and Mr.
Langton 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, 2000, the Committee had three 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, 2000, except that reports of initial ownership
were filed late for J. Kendall Huber, a Director of AAM, and Richard J.
Litchfield, a Vice President of AAM and of the Trust.

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 2002 must be received at the principal executive offices of the Trust, 440
Lincoln Street, Worcester, MA 01653, on or before November 1, 2001, for
inclusion in the proxy statement and proxy related to such meeting.

Messrs. O'Brien, Reilly, Kavanaugh and Litchfield, Ms. Tripp and Ms. Bushard
have been employees of AFC or its affiliates for the last five years. Mr. Kane
was Vice President/Treasurer of Tax & Financial Services, BISYS

Fund Services, 1997-1999, and Director of Shareholder Reporting, Fidelity
Investments, 1992-1997; Mr. Boyd was Director, Mutual Fund Administration--
Legal and Regulatory, Investors Bank & Trust Company, 1995-1996, and Vice

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.

Audit Fees, Financial Information Systems Design and Implementation Fees and
All Other Fees

Set forth below is a table listing the fees that were billed to the Trust
for audit and any non-audit services rendered by PricewaterhouseCoopers LLP,
the Trust's independent accountants, for the most recent fiscal year:

Financial
Information
Systems Design
and
Audit Implementation All Other
Fees Fees Fees
----- -------------- ---------

$24,800 None $7,350

The fees referenced above under "Financial Information Systems Design and
Implementation Fees" and "All Other Fees" not only include the services
rendered to the Trust, but also to the Trust's investment adviser or any
entity under common control with the adviser that provides services to the
Trust. This does not include any sub-adviser(s) whose principal role is
portfolio management and is sub-contracted or overseen by another investment
adviser. The fees listed above as "All Other Fees" relate to services for
auditing AAM.

The Trust's Audit Committee has determined that the provision of the non-
audit services referenced above is compatible with maintaining the independent
accountants' independence.

reporting process:

matters regarding SAS 61 (Codification of Statements on Auditing Standards,

accounting principles. This communication between the Audit Committee and

its oversight role in reviewing auditing procedures and evaluating the
audit function as a whole.

3. The Audit Committee has received and reviewed the written disclosures
and the letter from the independent accountants required by the
Independence Standards Board Standard No. 1, and has discussed with the
independent accountants the independent accountants' independence.

Trust that the audited financial statements be included in the Trust's
Annual Report to Shareholders for the last fiscal year.

The Audit Committee Report is submitted by the Audit Committee comprised

Committee are independent, as defined under applicable New York Stock
