*  Effective February 12, 2004, Mr. Parry replaced Mr. Hug as a Trustee.

   The Trust has no retirement or pension plan for its Trustees. None of the
Trustees who is not an "interested person" of the Trust, and none of their
respective immediate family members (spouse, child residing in household, and
dependents), owns any security of AFC or any of its affiliates. The Trust does
not have a compensation committee; such matters are considered by the Trust's
Governance Committee.

   The Trust's Fund Operations Committee is composed entirely of Trustees who
are not interested persons of the Trust, AFC or its affiliates. Currently, Dr.
Ott (Chairman), Mr. Condron, Ms. Davis, Ms. Hargadon, Mr. Harris, 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, 2003, 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 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, 2003, the Committee had four
meetings.

   The Trust's Investment Operations Committee is composed of three Trustees
who are not interested persons of the Trust, AFC or its affiliates and two
Trustees who are interested persons. Currently, Mr. Kavanaugh (Chairman), Ms.
Hargadon, Mr. Harris, 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, 2003, the Committee had four meetings
relating to the Trust.

   The Trust's Governance Committee is composed entirely of Trustees who are
not interested persons of the Trust, AFC or its affiliates and are independent.
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

                                      5



reviewing major personnel changes of the Trust. During the fiscal year ended
December 31, 2003, the Committee had three meetings. As required by regulations
promulgated by the SEC, a copy of the Governance Committee Charter is attached
as Appendix I. 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
A to the Governance Committee Charter, which is attached as Appendix I. Among
other requirements, these procedures provide that the 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. 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, 2003.

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.

                                      6



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 2005 must be received at the principal executive offices of the Trust, 440
Lincoln Street, Worcester, MA 01653, on or before November 1, 2004, 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, withholding authority to
vote, abstentions and broker nonvotes will have no effect on the outcome of the
voting on the matter.

appendix to the Trust's Proxy Statement at least once every three years or in
the next annual shareholders' meeting Proxy Statement after any significant
amendment to the charter. The Board of Trustees of the Trust has adopted an
amended written charter for the Audit Committee, which is attached as Appendix
III to this Proxy Statement.

Policy on Communication

   The Board of Trustees of the Trust has adopted procedures by which Trust
Shareholders may send communications to the Board. Shareholders may mail
written communications to the Board to the attention of the Board of Trustees,
Allmerica Securities Trust, c/o Secretary, 440 Lincoln Street, Mail Stop N440,
Worcester, MA 01653. Shareholder communications must (i) be in writing and be
signed by the Shareholder and (ii) identify the class and number of shares held
by the Shareholder. The Secretary of the Trust is responsible for reviewing
properly submitted shareholder communications. 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). The 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, or any communication made in connection with such a
proposal. The Trust's process for Shareholders to send communications to the
Board of Trustees is more fully described in its Policy Regarding the Ability
of Shareholders to Communicate with the Board of Trustees, which is attached
Appendix IV. The Trust's Trustees are not required to attend the Trust's annual
shareholder meetings or to otherwise make themselves available to Shareholders
for communications, other than by the aforementioned procedures. One Trustee
attended the 2003 annual meeting.

                     SHAREHOLDERS ARE URGED TO VOTE, SIGN
                      AND MAIL THEIR PROXIES IMMEDIATELY.

                          ALLMERICA SECURITIES TRUST

                         GOVERNANCE COMMITTEE CHARTER

Purpose of the Governance Committee

   The primary purpose of the Governance Committee (the "Committee") is to
nominate candidates for selection as Independent Trustees* of Allmerica
Investment Trust and Allmerica Securities Trust (the "Trusts") and their
committees and to establish policies and procedures relating to all Board of
Trustee service matters (including compensation), as well as other matters
concerning Trust governance.

Composition of the Governance Committee

   The Committee shall be composed of such number of the Independent Trustees
of the Trusts as may from time-to-time be designated by the Board of Trustees,
currently Cynthia A. Hargadon, T. Britton Harris IV, and Ranne P. Warner. The
Board of Trustees of the Trusts shall appoint one of the members of the
Committee to serve as the Committee Chairperson (the "Chair"), currently Ranne
P. Warner.

Procedures for Nominating New Independent Trustees

   At the direction of the Boards of Trustees of the Trusts, the Committee will
nominate candidates for election as Independent Trustees of the Fund using the
following procedures:

    1. The Chair shall obtain suggestions for prospective Independent Trustees
       from current Independent Trustees of the Trusts, from the Trusts'
       management, Trust shareholders** and from other appropriate sources,
       including, if necessary, outside consultants, and will, to the extent
       feasible and appropriate, maintain all names received in confidence.

    2. The Chair will provide each Committee Member with the name and
       background information of each candidate at least one week prior to the
       first meeting of the Committee at which the candidate is to be
       discussed, if possible.

    3. At a meeting of the Committee at a time to be selected by the Chair, the
       Committee will discuss all candidates whose names have been submitted to
       the Chair. The Committee by majority vote may remove individuals from
       further consideration and may prepare a schedule establishing priorities
       for considering candidates in addition to the criteria set forth below.
       For example, the Committee may determine in certain circumstances that a
       candidate ideally should possess a particular type of business
       experience or professional expertise (e.g., in order to replace
       expertise possessed by retiring trustee, etc.).

    4. The Chair will arrange for information about candidates selected for
       further consideration to be reviewed by the Trustee's Independent
       Counsel, who will determine based upon this information whether a
       candidate has any legal impediments to serving as an Independent Trustee
       of the Trusts. Counsel will inform the Chair of the results of this
       review.

    5. The Committee will review further the candidates as it deems necessary
       before proposing candidates to the Independent Trustees for nomination.
       Such review may involve establishing subcommittees of the Governance
       Committee to interview candidates, obtaining further information about a
       candidate, and inviting other Independent Trustees to participate, as
       desired.

    6. The Committee will not differentiate among candidates based upon any
       characteristic prohibited under applicable laws and regulations.
- --------
*  The Independent Trustees are those Trustees of the Trusts who are not
   "interested persons" (as defined in the Investment Company Act of 1940) of
   the Trusts, Allmerica or any sub-adviser to the Trusts.
** For purposes of this Charter, shareholders of Allmerica Investment Trust
   mean contractholders and policyholders of variable insurance products that
   use the Funds of the Trust as investment vehicles.



Recommendations by Shareholders for New Independent Trustees

   The Committee will consider and evaluate nominee candidates properly
submitted by shareholders of the Trusts. Appendix A to this Charter, as it may
be amended from time to time by the full Board of Trustees, sets forth
procedures that must be followed by shareholders to properly submit a nominee
candidate to the Committee (recommendations not properly submitted in
accordance with Appendix A will not be considered by the Committee).

   There are no material differences in the manner in which the Committee
evaluates Trustee candidates based on whether the candidate is recommended by a
shareholder.

Qualification of Independent Trustees

   In their consideration of candidates to be proposed as nominees for
positions as Independent Trustees of the Trusts, the Trusts' Trustees should
ensure that to the extent practicable, a candidate have all of or substantially
all of the following qualifications:

    1. A stringent dedication to the legal, ethical, and fiduciary constraints
       imposed on the Independent Trustees of a mutual fund.

    2. A reputation for ethical and honest dealings and behavior, and a high
       standing in his or her business and/or professional dealings and in the
       community.

    3. Freedom from real or perceived conflicts of interest, beyond those
       formally proscribed by the Investment Company Act of 1940.

    4. An ability to devote the considerable amount of time necessary to
       perform the duties of a Trustee, including a commitment in the ordinary
       course to attend all Trust Board and Committee Meetings.

    5. An independent approach to issues, with confidence in his or her
       judgment that permits taking positions which may not be favored by
       management or others, in combination with a personality compatible with
       other Trustees, an ability to work well in a group setting and a
       recognition of the desirability and importance of Trustee consensus.

    6. An ability, through past experience or wisdom, to recognize the
       differences between exercising a "macro" and "micro" managerial role and
       to be comfortable with the proper role of an Independent Trustee, which
       is one of broad oversight of the Trusts as opposed to micro management
       of Trust processes and operations.

    7. Sufficient business and life experience to have developed a requisite
       level of "judgment."

    8. Commitment to serve a substantial period of time on the Boards.

    9. Preferably, a background including one or more of the following:

       a. Some form of investment or financial experience.

       b. Management experience (ideally CEO, COO, or CFO or other executive
          level experience) in a company.

       c. Experience practicing as an attorney or accountant, either in private
          practice or as a corporate employee, ideally with an emphasis on
          financial and business matters.

       d. Leadership experience in the public sector, or other significant
          organizations.

       e. Academic experience, on a university-level, preferably involving
          administration as well at teaching (dean of a college of business)
          and ideally a financial or business related discipline.

    10.A background which is compatible with, but also sufficiently different
       from, other Trustees, to add an expertise not otherwise represented on
       the Boards of the Trusts.

                                      2

       special meetings as circumstances require.

    2. The Committee shall review this Charter periodically and recommend any
       changes to the full Board of Trustees.

Originally Adopted: May 12, 1998
Revised: February 12, 2004



                                                                    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 Sarbanes-Oxley Act
       of 2002 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.



                                                                   APPENDIX III

                          ALLMERICA INVESTMENT TRUST
                          ALLMERICA SECURITIES TRUST

                            AUDIT COMMITTEE CHARTER

    1. Composition: The Audit Committee shall be composed of not less than
       three Trustees who are elected by a majority of the full Board of
       Trustees. Each Trustee who is a member of the Committee shall be an
       unaffiliated, non-interested person, as defined under the Investment
       Company Act of 1940 (the "1940 Act") and, with respect to Allmerica
       Securities Trust, an independent Trustee in accordance with New York
       Stock Exchange (NYSE) rules. All members of the Audit Committee must be
       "financially literate," i.e., familiar with basic finance and accounting
       practices, and at least one member of the Committee must have accounting
       or related financial management expertise. Financial literacy shall be
       determined in accordance with NYSE rules. The Committee shall appoint a
       Chairperson to preside at all meetings of the Committee.

    2. Purpose: The purpose of the Audit Committee is to assist Board oversight
       of: (a) the integrity of the Trusts' financial statements; (b) the
       Trusts' compliance with legal and regulatory requirements; (c) the
       qualifications and independence of the Trusts' independent auditors; and
       (d) the operation of the Trusts' internal control systems and the
       performance of the Trusts' independent auditors. The Committee assists
       the Trustees in determining that the assets of the Trust are properly
       safeguarded and valued and that the Trusts' policies are being carried
       out, and in monitoring the Trusts' financial reporting to their
       shareholders, the general public and applicable regulatory agencies.
       With respect to Allmerica Securities Trust, the Committee's purpose is
       also to prepare reports required by the U.S. Securities and Exchange
       Commission rules to be included in the Trust's annual proxy statements,
       if any.

    3. General responsibilities of the Audit Committee are:

      (a) to oversee the Trusts' accounting and financial reporting process and
   their internal control over financial reporting, and, as the Committee deems
   appropriate, to inquire into the internal control over financial reporting
   of certain third-party service providers of the Trusts;

      (b) to oversee the quality and objectivity of the Trusts' financial
   statements and the audit thereof by the Trusts' independent auditors; and

      (c) to act as a liaison between the Trusts' independent auditors and the
   full Board of Trustees.

       The Committee is directly responsible for the appointment, compensation,
       retention, and oversight of the work of the independent auditors engaged
       (including resolution of disagreements between management and the
       independent auditors regarding financial reporting) for the purpose of
       preparing or issuing an audit report or performing other audit and
       review services for the Trusts. The Trusts' independent auditors shall
       report directly to the Committee.

       While the Committee has the responsibility and powers set forth in this
       Charter, it is not the duty of the Committee (i) to plan or conduct
       audits, which is the responsibility of the independent auditors, (ii) to
       maintain or arrange for the maintenance of appropriate systems for
       accounting and internal controls, or (iii) to determine that the Trusts'
       financial statements are complete and accurate and are in accordance
       with generally accepted accounting principles, which are the
       responsibilities of the Trusts' management.

    4. To carry out the responsibilities listed in item 3, the Audit Committee
       shall have the following duties and powers:

      (a) at least annually, to obtain and review a report by the independent
   auditors describing: (i) the firm's internal quality-control procedures;
   (ii) any material issues raised by the most recent internal quality-control
   review, or peer review, of the firm, or by any inquiry or investigation by
   governmental or professional



   authorities, within the preceding five years, respecting one or more
   independent audits carried out by the firm, and any steps take to deal with
   any such issues; and (iii) in order to assess the auditors' independence,
   all relationships between the independent auditors, the Trusts, the
   investment adviser or sub-adviser(s) of the Trusts or their affiliates.

      (b) to meet with the Trusts' independent auditors, including private
   meetings, as necessary (i) to review the arrangements for and scope of the
   annual audit and any special audits; (ii) to discuss any matters of concern
   relating to the Trusts' financial statements, including any adjustments to
   such statements recommended by the auditors, or other results of said
   audit(s) and management's responses thereto; (iii) to consider the auditors'
   comments with respect to the Trusts' financial policies, procedures and
   internal control over financial reporting and, as appropriate, the controls
   of the Trusts' custodian, transfer agent and other service providers, and
   management's responses thereto; (iv) to review the form of opinion the
   auditors propose to render to the Board and shareholders; and (v) to review
   with a representative of the Trusts' management and the independent auditors
   the financial information and other disclosure contained in the Trusts'
   annual report to shareholders under Section 30(e) of the 1940 Act and Rule
   30d-1 thereunder prior to its filing; and, with respect to Allmerica
   Securities Trust, the Charter will be included as an appendix to any annual
   shareholders' meeting proxy statement at least once every three years, or in
   the next annual shareholders' meeting proxy statement after any significant
   amendment to the Charter;

      (c) to review (i) major issues regarding accounting principles and
   financial statement presentations, including any significant changes to the
   Trusts' selection or application of accounting principles, and major issues
   as to the adequacy of the Trusts' internal control over financial reporting
   and any special audit steps adopted in light of material control
   differences, and (ii) the effect of regulatory and accounting initiatives on
   the financial statements of the Trusts;

      (d) to review the fees charged by the auditors for audit and non-audit
   services;

      (e) to investigate improprieties or suspected improprieties in the
   Trusts' accounting or financial reporting, and to review with counsel to the
   Trusts legal matters that may have a material impact on the financial
   statements, the Trusts' compliance policies and any material reports or
   inquiries received from regulatory or governmental agencies relating to
   financial matters;

      (f) if applicable, review any analyses prepared by the Trusts' management
   and/or independent auditors of significant financial reporting issues and
   judgments (including issues relating to the valuation of the Trusts'
   portfolio securities) made in connection with the preparation of the Trusts'
   financial statements, including any analyses of the effects of alternative
   approaches under generally accepted accounting principles on the Trusts'
   financial statements;

      (g) to meet periodically with the Trusts' management and independent
   auditors to review the Trusts' policies with respect to risk assessment and
   risk management, the Trusts' major financial risk exposures, and the steps
   taken to monitor and control such exposures;

      (h) to review the experience and qualifications of the senior members of
   the Trusts' audit team and the Trusts' Treasurer and the quality control
   procedures of the independent auditor;

      (i) to review matters brought to the attention of the Board of Trustees
   by the Trusts' investment adviser or sub-adviser(s) or independent auditors
   involving the valuation of Trust assets, including fair valuation and
   single-source pricing;

      (j) to the extent required by applicable regulations, to approve all
   audit and non-audit services rendered to the Trusts by the auditors and all
   non-audit services to the Trusts' investment adviser and certain of its
   affiliates, and to review the fees charged by the auditors for audit and
   non-audit services, provided, however, that the Audit Committee may
   implement policies and procedures pursuant to which services are
   pre-approved other than by the full Audit Committee, subject to the
   requirement that the full Audit Committee be notified in a timely manner of
   each such service;

      (k) to review such other matters or information that the Committee
   believes may be relevant to the auditors, the audit engagement or the
   Trusts' financial policies and procedures or internal control over

                                      2



   financial reporting, and to report on the independent auditors' report and
   the Committees' activities to the full Board on a regular and timely basis
   and to make such recommendations with respect to the above and other matters
   as the Committee may deem necessary or appropriate;

      (l) to establish procedures for (i) the receipt, retention, and treatment
   of complaints received by the Trusts regarding accounting, internal
   accounting controls, or auditing matters; and (ii) the confidential,
   anonymous submission by employees of the Trusts, the investment advisers and
   sub-advisers of the Trusts, administrator, principal underwriter (if any),
   or any other provider of accounting-related services for the investment
   advisers and sub-advisers of concerns regarding accounting or auditing
   matters;

      (m) to discuss with management any press releases discussing the
   investment performance of the Trusts and other financial information about
   the Trusts, as well as any financial information provided by management to
   analysts or rating agencies. The Committee may discharge this responsibility
   by discussing the general types of information to be disclosed by the Trusts
   and the form of presentation (i.e., a case-by-case review is not required)
   and need not discuss in advance each such release of information;

      (n) if and to the extent that the Trusts intend to have employees, to set
   clear policies for the hiring by the Trusts of employees or former employees
   of the independent auditors; and

      (o) to perform other oversight functions, adopt such policies and
   procedures and conduct other reviews not referenced in this Charter as
   requested from time to time by the Board or required by applicable law.

    5. The Audit Committee shall meet on a regular basis as determined
       necessary or appropriate by the Board of Trustees, but in no event less
       than twice per year, and is empowered to hold special meetings as
       circumstances require.

    6. The Audit Committee shall maintain minutes of its meetings to be kept
       with the records of the Trusts.

    7. The Audit Committee shall meet separately and on a periodic basis with
       the independent auditors, the Treasurer of the Trust and other members
       of management, or at such other times as the Committee deems necessary
       or appropriate.

    8. The Audit Committee shall have the resources and authority appropriate
       to discharge its responsibilities, including the authority to retain
       special counsel, accounting and other experts or consultants at the
       expense of the Trusts. The Committee may request any officer or employee
       of the Trusts or of any of the Trusts' service providers or the Trusts'
       outside counsel or independent auditors to attend a meeting of the
       Committee or to meet with any member of, or consultants to, the

                 POLICY REGARDING THE ABILITY OF SHAREHOLDERS
                   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:
       Board of Trustees, [insert name of Trust], c/o Secretary, 440 Lincoln
       Street, Mail Stop N440, Worcester, MA 01653.

    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).
