   The Trust's Fund Operations Committee is composed entirely of Trustees who
are not interested persons of the Trust. Currently, Dr. Ott (Chairman), Mr.
Condron, Ms. Davis, Ms. Hargadon, Mr. Holmes and Ms. Warner comprise the
Committee. The Committee separately reviews and makes recommendations to the
Trustees on a variety of matters, including the various contractual
arrangements between the Trust and its investment adviser and transfer and
shareholder servicing agent, proposals to continue or modify the terms of such
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
the fiscal year ended December 31, 2004, the Committee had two meetings
relating to the Trust.

   The Trust's Audit Committee is composed entirely of Trustees who are not
interested persons of the Trust. Currently, Mr. Holmes (Chairman), Mr. Condron,
Ms. Davis, Ms. Hargadon, Dr. Ott and Ms. Warner comprise the Committee. This
Committee reviews and evaluates the audit function, including selecting the
independent accountants 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, 2004, the Committee had five
meetings.

   The Trust's Investment Operations Committee is composed of six Trustees who
are not interested persons of the Trust and two Trustees who are interested
persons of the Trust. Currently, Mr. Kavanaugh (Chairman), Mr. Condron, Ms.
Davis, Ms. Hargadon, Mr. Holmes, Dr. Ott, Mr. Parry and Ms. Warner serve on the
Committee. The Committee monitors investment adviser performance and analyzes
Fund data. During the fiscal year ended December 31, 2004, the Committee had
five meetings relating to the Trust.

   The Trust's Governance Committee is composed entirely of Trustees who are
not interested persons of the Trust. Currently Ms. Warner (Chairman), Mr.
Condron, Ms. Davis, Ms. Hargadon, Mr. Holmes, and Dr. Ott 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, 2004, the
Committee had four meetings. As required by regulations promulgated by the SEC,
a copy of the Governance Committee Charter was included as an appendix to the
Trust's proxy statement for the annual meeting of shareholders held on April
21, 2004. The Trust currently does not make the Governance Committee Charter
available to shareholders on its website.

   When evaluating Trustee candidates, the Trust's Governance Committee takes
into account a wide variety of factors including, but not limited to: (i)
availability and commitment of a candidate to attend meetings and perform his
or her responsibilities on the Board, (ii) relevant industry and related
experience, (iii) educational background, (iv) financial expertise, (v) an
assessment of the candidate's ability, judgment and expertise and (vi)
reputation for ethical and honest dealings and behavior. The process of
identifying nominees involves the consideration of candidates recommended by
one or more of the following sources: (i) the Trust's current Trustees, (ii)
the Trust's investment adviser, (iii) the Trust's shareholders and (iv) any
other source the Committee deems to be appropriate. The Governance Committee
may, but is not required to, retain an outside consulting firm at the Trust's
expense to identify potential candidates.

   The Governance Committee will review and consider nominees recommended by
shareholders to serve as Trustee, provided that the recommending shareholder
follows the procedures for submitting recommendations as set forth in Appendix
I attached hereto. Among other requirements, these procedures provide that the

                                      6



recommending shareholder must submit any recommendation in writing to the
Trust, to the attention of the Trust's Secretary, at the address of the
principal executive offices of the Trust and that such submission must be
received at such offices not less than 45 days nor more than 75 days prior to
the date of the Board or shareholder meeting at which the nominee would be
elected. Any recommendation must include certain biographical and other
information regarding the candidate and the recommending shareholder, and must
include a written and signed consent of the candidate to be named as a nominee
and to serve as a Trustee, if elected. The foregoing description of the
requirements is only a summary. Please refer to Appendix I for details.

   The Governance Committee has full discretion to reject nominees recommended
by Shareholders, and there is no assurance that any such person properly
recommended and considered by the Committee will be nominated for election to
the Board 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 ("NYSE"). 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, 2004.

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).

                                      7



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 2006 must be received at the principal executive offices of the Trust, 440
Lincoln Street, Worcester, MA 01653, on or before November 1, 2005, for
inclusion in the proxy statement and proxy related to such meeting.

   The individuals named above have been employees of AFC or its affiliates for
the last five years.

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.

Independent Public Accountants

   The following information describes the Trust's relationship with its
independent public accountants, PricewaterhouseCoopers LLP ("PWC"), and certain
fiscal year fees. The Audit Committee's Policy for Pre-Approval of Services
Provided by Independent Auditors (the "Pre-Approval Policy") is attached as

   All fees disclosed above under the captions "Audit-Related Fees," "Tax

required to be pre-approved, and which were so pre-approved, by the
registrant's Audit Committee in accordance with the Audit Committee's Policy
for Pre-Approval of Services Provided by Independent Auditors.

   For the last two fiscal years of the registrant, the independent accountants
billed aggregate non-audit fees in the following amounts to the registrant and
Opus Investment Management, Inc. ("Opus"), the Trust's investment adviser:


  
2004 $3,500
2003 $3,300


   The Trust's Audit Committee has determined that the provision by PWC of
non-audit services that were rendered to OIM and that were not pre-approved by
the Audit Committee were compatible with maintaining the independence of PWC.

accountants for services required to be approved pursuant to paragraph

       matters regarding SAS 61 (Codification of Statements on Auditing
       Standards, AU 380) relating to the quality and consistency of accounting
       principles. This communication between the Audit Committee and the
       independent accountants will assist the Audit Committee in performing
       its oversight role in reviewing auditing procedures and evaluating the
       audit function as a whole.

    3. The Audit Committee has received the written disclosures and the letter
       from the independent accountants required by the Independence Standards

       the independent accountants' independence.

    4. The Audit Committee has recommended to the Board of Trustees of the
       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 of
Gordon Holmes (Chairman), P. Kevin Condron, Jocelyn S. Davis, Cynthia A.

                                  APPENDIX II

     Policy for Pre-Approval of Services Provided by Independent Auditors

1. At the beginning of each audit cycle (typically at the August Audit
   Committee meeting), certain types of recurring audit, audit related and
   other services are to be pre-approved including:

    (a)the list of required audits and projects presented by the audit firm at
       the August meeting;

    (b)any required audits that emerge during the year, attestation services,
       and other audit scope increases that were not known at the August
       report, where it is most appropriate, for either efficiency or
       effectiveness, that the service be performed by the independent auditors;

    (c)consultation and advisory services related to accounting/reporting and
       risk management/control matters provided in the normal course of
       business, where it is most appropriate, for either efficiency or
       effectiveness, that the service be performed by the independent
       auditors; and

    (d)assistance with SEC and other regulatory filings and tax services
       incurred in the normal course of business, including consulting on
       federal, state and foreign tax matters, including income taxes,
       franchise and similar taxes.

   This pre-approval will occur concurrently with the approval of the annual
   audit fees and will apply to all individual projects meeting the above
   criteria and which are expected to result in total fees less than $400,000.
   For individual projects outside the scope of the fiscal year audits and tax
   return filings expected to be $25,000 or greater, specific pre-approval will
   be necessary.

2. Pre-approvals for all other services will occur if and when the need for any
   such services arises. This pre-approval will be initiated by management and
   will be requested from the Chairman or, in the event the Chairman is
   unavailable, any other member of the Audit Committee.

   Any services approved by the Chairman, or other Audit Committee member, at
   any time other than during an Audit Committee meeting will be reported to
   the full Audit Committee at the next regularly scheduled meeting.

3. De minimis expenses allowed under Section 202 of the Act will not require
   pre-approval.

At each regularly scheduled meeting of the Audit Committee, the Trusts'
Treasurer will report on any such projects begun during the period since the
last such report, and on any fees incurred on existing projects during this
same intervening period.

                   to Communicate with the Board of Trustees

Purpose of the Policy

   The primary purpose of this policy is to explain the process for
shareholders* to send communications to the Board of Trustees of Allmerica
Investment Trust and Allmerica Securities Trust (the "Trusts").

Procedure for Sending Communications

    1. Shareholders should mail communications to the Board of Trustees to:

    2. A shareholder communication must (i) be in writing and be signed by the
       shareholder, (ii) identify the Trust or series thereof to which it
       relates and (iii) identify the class and number of shares held by the
       shareholder.

    3. These Procedures shall not apply to (i) any communication from an
       officer or Trustee of the Trust, (ii) any communication from an employee
       or agent of the Trust, unless such communication is made solely in such
       employee's or agent's capacity as a shareholder, or (iii) any
       shareholder proposal submitted pursuant to Rule 14a-8 under the
       Securities Exchange Act of 1934, as amended, or any communication made
       in connection with such a proposal.

    4. The Trustees are not required to attend the Trust's annual shareholder
       meetings (with respect to Allmerica Securities Trust) or to otherwise
       make themselves available to shareholders for communications, other than
       pursuant to these Procedures.

    5. The Secretary of the Trust may, in good faith, determine that a
       shareholder communication should not be provided to the Board because it
       does not reasonably relate to the Trust or its operations, management,
       activities, policies, service providers, Board, officers, shareholders
       or other matters relating to an investment in the Trust or is otherwise
       ministerial in nature (such as a request for Trust literature, share
       data or financial information).
