PROXY STATEMENT

A proxy is enclosed with the foregoing Notice of the Annual Meeting of
Shareholders of Eaton Vance Senior Income Trust (the "Fund"), to be held October
15, 2004 for the benefit of shareholders who do not expect to be present at the
meeting. This proxy is solicited on behalf of the Board of Trustees of the Fund,
and is revocable by the person giving it prior to exercise by a signed writing
filed with the Fund's Secretary, or by executing and delivering a later dated
proxy, or by attending the meeting and voting the shares in person. Each proxy
will be voted in accordance with its instructions; if no instruction is given,
an executed proxy will authorize the persons named as attorneys, or any of them,
to vote in favor of the election of each Trustee. This proxy material is being
mailed to shareholders on or about August 27, 2004.

The Board of Trustees of the Fund has fixed the close of business August
20, 2004, as the record date for the determination of the shareholders entitled
to notice of and to vote at the meeting and any adjournments thereof.
Shareholders at the close of business on the record date will be entitled to one
vote for each share held. As of August 20, 2004, there were 36,361,355 Common
Shares of beneficial interest, $.01 par value per share ("Common Shares") and
4,400 Auction Preferred Shares, $.01 per value per share, liquidation preference
$25,000 per share ("APS"), of the Fund outstanding. As of such date, to the
Fund's knowledge, (i) no shareholder beneficially owned more than 5% of the
outstanding shares; and (ii) the Trustees and executive officers of the Fund,
individually and as a group, owned beneficially less than 1% of the outstanding
shares of the Fund.

The Board of Trustees of the Fund knows of no business other than that
mentioned in Item 1 of the Notice of Meeting which will be presented for
consideration. If any other matters are properly presented, it is the intention
of the persons named as attorneys in the enclosed proxy to vote the proxies in
accordance with their judgment on such matters.

PROPOSAL 1. ELECTION OF TRUSTEES

The Fund's Declaration of Trust provides that a majority of the Trustees
shall fix the number of the entire Board and that such number shall be at least
two and no greater than fifteen. The Board has currently fixed the number of
Trustees at six. The Fund's Declaration of Trust further provides that the Board
of Trustees shall be divided into three classes. The term of office of the Class
III Trustees expires on the date of the 2004 Annual Meeting, and the term of
office of the Class I and Class II Trustees will expire one and two years
thereafter, respectively. Accordingly, only nominees for Class III Trustee are
currently proposed for election. Trustees chosen to succeed the Trustees whose
terms are expiring will be elected for a three-year term. An effect of staggered
terms is to limit the ability of entities or persons to acquire control of the
Fund.

Proxies will be voted for the election of the following Class III Trustee
nominees: William H. Park and Lynn A. Stout. Each nominee is currently serving
as a Trustee and has consented to continue to so serve. In the event that a
nominee is unable to serve for any reason (which is not now expected) when the
election occurs, the accompanying Proxy will be voted for such other person or
persons as the Board of Trustees may recommend.

The Class I Trustees serving until the 2005 Annual Meeting are James B.
Hawkes and Ronald A. Pearlman. The Class II Trustees serving until the 2006
Annual Meeting are Samuel L. Hayes, III and Norton H. Reamer.

The nominees for Class III Trustee and the Fund's current Class I and Class
II Trustees and their principal occupations for at least the last five years are
as described below.

INTERESTED TRUSTEES

James B. Hawkes is an "interested person" (as defined in the Investment
Company Act of 1940 (the "1940 Act")) by reason of his affiliations with Eaton
Vance Management ("EVM" or "Eaton Vance"), the Fund's investment adviser, and
Eaton Vance Corp. ("EVC"), a publicly traded holding company which indirectly
owns all the outstanding shares of EVM, and of EVM's trustee, Eaton Vance, Inc.
("EV"), which is a wholly-owned subsidiary of EVC. (EVM, EVC, and their
affiliates are sometimes referred to collectively as the "Eaton Vance
Organization".)

ELECTION OF TRUSTEES BY APS AND COMMON SHARES

Under the terms of the Fund's By-Laws, as amended (the "By-Laws"), the
holders of the APS are entitled as a class, to the exclusion of the holders of
the Common Shares, to elect two Trustees of the Fund (identified by an "(A)"
after their names in the table above). Simply stated, the APS Trustees are only
elected by the holders of the Fund's Auction Preferred Shares. Holders of Common
Shares do not vote on the election of APS Trustees. No APS Trustees are to be
elected at this meeting. The By-Laws further provide for the election of the
nominees named above by the holders of the Common Shares and the APS, voting as
a single class. Election of Trustees is non-cumulative. The Trustees of the Fund
shall be elected by a plurality of the shares of the Fund entitled to vote.

The following table shows the dollar range of shares beneficially owned in
the Fund and in all Eaton Vance funds by each Trustee:

BOARD MEETINGS AND COMMITTEES

During the fiscal year ended June 30, 2004, the Trustees of the Fund met
ten times. The Board of Trustees has three formal standing committees, an Audit
Committee, a Special Committee and a Governance Committee. The Audit Committee
met four times, the Special Committee met four times and the Governance
Committee met five times. Each Trustee attended at least 75% of the Board and
committee meetings on which he or she serves.

The Audit, Special and Governance Committees of the Board of Trustees of
the Fund are each comprised of Trustees who are not "interested persons" as that
term is defined under the 1940 Act ("Independent Trustees"). The respective
duties and responsibilities of these Committees remain under the continuing
review of the Governance Committee and the Board.

Messrs. Reamer (Chair), Hayes, Park and Ms. Stout serve on the Audit
Committee of the Board of Trustees of the Fund. Each Audit Committee member is
independent under the listing standards of the New York Stock Exchange. The
purposes of the Audit Committee are to (i) oversee the Fund's accounting and
financial reporting policies and practices, its internal audit controls and
procedures, the internal controls of certain service providers, as appropriate,
and the quality and integrity of the Fund's financial statements and independent
audit thereof; (ii) approve the selection, evaluation, and, when appropriate,
replacement of the Fund's independent registered public accounting firm; and
(iii) evaluate the qualifications, independence, and performance of the Fund's
independent registered public accounting firm. The Fund's Board of Trustees has
adopted a written charter for its Audit Committee, a copy of which is attached
as Exhibit A. The Audit Committee's Report is set forth below under "Additional
Information". The Board of Trustees of the Fund have designated Messrs. Park,
Hayes and Reamer as the Fund's Audit Committee financial experts.

Messrs. Hayes (Chair), Park, Pearlman and Reamer serve on the Special
Committee of the Board of Trustees of the Fund. The purposes of the Special
Committee are to consider, evaluate and make recommendations to the Board of
Trustees concerning the following matters: (i) contractual arrangements with
each service provider to the Fund, including advisory, sub-advisory, transfer
agency, custodial and fund accounting, distribution services (if any) and
administrative services; (ii) any and all other matters in which any of the
Fund's service providers (including Eaton Vance or any affiliated entity
thereof) has an actual or potential conflict of interest with the interests of
the Fund or its shareholders; and (iii) any other matter appropriate for review
by the Independent Trustees, unless the matter is within the responsibilities of
the Audit Committee or the Governance Committee of the Fund.

In February 2004, the Special Committee established a Contract Review
Subcommittee to act on matters delegated to it by the Special Committee,
including matters relating to the Fund's investment advisory agreement and other
service contracts, expense allocation, the Fund's directors' and officers'
errors and omissions insurance coverage, and actual or potential conflicts of

interest between Eaton Vance and its affiliated companies, on the one hand, and
the Fund on the other hand. The Contract Review Subcommittee is comprised of
Messrs. Hayes (Chair), Park, Pearlman and Reamer and has met six times during
the fiscal year ended June 30, 2004. On August 16, 2004, the Special Committee
approved a revised Special Committee Charter which eliminated the Contract
Review Subcommittee, because it was determined that its function could be
carried out by the full Special Committee.

Ms. Stout (Chair) and Messrs. Hayes, Park, Pearlman and Reamer serve on the
Governance Committee of the Board of Trustees of the Fund. The purpose of the
Governance Committee is to consider, evaluate and make recommendations to the
Board of Trustees with respect to the structure, membership and operation of the
Board of Trustees and the Committees thereof, including the nomination and
selection of Independent Trustees and the compensation of Independent Trustees.
The Fund's Board of Trustees has adopted a written charter for its Governance
Committee, a copy of which is attached as Exhibit B. The Governance Committee's
procedures for identifying and evaluating candidates for the position of
Independent Trustee, including the procedures to be followed by shareholders of
the Fund wishing to recommend such candidates for consideration by the
Governance Committee, are set forth in Appendix A to the Committee's charter.

COMMUNICATIONS WITH THE BOARD

Shareholders wishing to communicate with the Board may do so by sending a
written communication to any Chairperson of the Audit Committee, Special
Committee or Governance Committee or to the Independent Trustees as a group, at
the following address: The Eaton Vance Building, 255 State Street, Boston,
Massachusetts 02109, c/o the Secretary of the Fund.

REMUNERATION OF TRUSTEES

The fees and expenses of those Trustees of the Fund who are not members of
the Eaton Vance Organization will be paid by the Fund. For the fiscal year ended
June 30, 2004, the Trustees of the Fund earned the following compensation in
their capacities as Trustees of the Fund, and for the year ended December 31,
2003 earned the following compensation in their capacities as Trustees of the
funds in the Eaton Vance fund complex(1):

TOTAL
AGGREGATE COMPENSATION
COMPENSATION FROM FUND
NAME OF TRUSTEE FROM FUND AND FUND COMPLEX
--------------- --------- ----------------
Samuel L. Hayes, III $ 3,076 $ 183,750
William H. Park 2,763 98,333(2)
Ronald A. Pearlman 2,770 85,000
Norton H. Reamer 2,904 170,833
Lynn A. Stout 2,892 167,500(3)

(1) As of August 1, 2004, the Eaton Vance fund complex consisted of 197
registered investment companies or series thereof.
(2) Includes $60,920 of deferred compensation.
(3) Includes $23,250 of deferred compensation.

Trustees of the Fund who are not affiliated with Eaton Vance may elect to
defer receipt of all or a percentage of their annual fees in accordance with the
terms of a Trustees Deferred Compensation Plan (the "Trustees' Plan"). Under the
Trustees' Plan, an eligible Trustee may elect to have his deferred fees invested
by the Fund in the shares of one or more funds in the Eaton Vance fund complex,
and the amount paid to the Trustees under the Trustees' Plan will be determined
based upon the performance of such investments. Deferral of Trustees' fees in
accordance with the Trustees' Plan will have a negligible effect on the Fund's
assets, liabilities, and net income per share, and will not obligate the Fund to
retain the services of any trustee or obligate the Fund to pay any particular
level of compensation to the Trustee. The Fund does not have a retirement plan
for its Trustees.

THE BOARD OF TRUSTEES RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE ELECTION OF
THE TWO CLASS III NOMINEES.

NOTICE TO BANKS AND BROKER/DEALERS

The Fund has previously solicited all Nominee and Broker/Dealer accounts as
to the number of additional proxy statements required to supply owners of
shares. Should additional proxy material be required for beneficial owners,
please forward such requests to PFPC Inc., Attention: Ms. Maura Stanley, P.O.
Box 43027, Providence, RI 02940-3027.

ADDITIONAL INFORMATION

AUDIT COMMITTEE REPORT

The Audit Committee reviewed and discussed the audited financial statements
with Fund management. The Audit Committee also discussed with the independent
registered public accounting firm the matters required to be discussed by SAS 61
(Codification of Statements on Auditing Standards). The Audit Committee received
the written disclosures and the letter from the independent registered public
accounting firm required by Independence Standards Board Standard No. 1
(Independence Standards Board Standard No. 1, Independence Discussions with
Audit Committees), and discussed with the independent registered public
accounting firm their independence.

Based on the review and discussions referred to above, the Audit Committee
recommended to the Board of Trustees that the audited financial statements be
included in the Fund's annual report to shareholders for the fiscal year ended
June 30, 2004 for filing with the Securities and Exchange Commission.

AUDITORS, AUDIT FEES AND ALL OTHER FEES. Deloitte & Touche LLP ("Deloitte"), 200
Berkeley Street, Boston, Massachusetts 02116, serves as independent registered
public accounting firm of the Fund. Deloitte is expected to be present at the
Annual Meeting, but if not, a representative will be available by telephone
should the need for consultation arise. Representatives of Deloitte will have
the opportunity to make a statement if they desire to do so and will be
available to respond to appropriate questions.

The following table presents the aggregate fees billed to the Fund for each
of the two fiscal years ended June 30, 2004 by the Fund's principal accountant
for professional services rendered for the audit of the Fund's annual financial
statements and fees billed for other services rendered by the principal
accountant during these periods.

FISCAL YEAR ENDED 6/30/03 6/30/04
------------------------------------------------------------

Audit Fees $ 84,666 $ 87,179
Audit-Related Fees(1) 31,930 21,218
Tax Fees(2) 6,000 6,100
All Other Fees(3) - -
-----------------------
Total $122,596 $114,497
=======================

(1) Audit-related fees consist of the aggregate fees billed for assurance and
related services that are reasonably related to the performance of the
audit of the Fund's financial statements and are not reported under the
category of audit fees and specifically include fees for the performance of
certain agreed-upon procedures relating to the Fund's APS.

(2) Tax fees consist of the aggregate fees billed for professional services
rendered by the principal accountant relating to tax compliance, tax
advice, and tax planning and specifically include fees for tax return
preparation.

(3) All other fees consist of the aggregate fees billed for products and
services provided by the Fund's principal accountant other than audit,
audit-related, and tax services.

No services described in the table above were approved by the Fund's Audit
Committee pursuant to the "de minimis exception" set forth in Rule
2-01(c)(7)(i)(C) of Regulation S-X.

The Fund's Audit Committee has adopted policies and procedures relating to
the pre-approval of services provided by the Fund's principal accountant (the
"Pre-Approval Policies"). The Pre-Approval Policies establish a framework
intended to assist the Audit Committee in the proper discharge of its
pre-approval responsibilities. As a general matter, the Pre-Approval Policies
(i) specify certain types of audit, audit-related, tax, and other services
determined to be pre-approved by the Audit Committee; and (ii) delineate
specific procedures governing the mechanics of the pre-approval process,
including the approval and monitoring of audit and non-audit service fees.
Unless a service is specifically pre-approved under the Pre-Approval Policies,
it must be separately pre-approved by the Audit Committee. The Pre-Approval
Policies and the types of audit and non-audit services pre-approved therein must
be reviewed and ratified by the Fund's Audit Committee at least annually. The
Fund's Audit Committee maintains full responsibility for the appointment,
compensation, and oversight of the work of the Fund's principal accountant.

The following table presents (i) the aggregate non-audit fees (i.e., fees
for audit-related, tax, and other services) billed to the Fund by the Fund's
principal accountant for the Fund's two fiscal years ended June 30, 2004; and
(ii) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other
services) billed to the Eaton Vance Organization by the Fund's principal
accountant for the two fiscal years ended June 30, 2004.

FISCAL YEAR ENDED 6/30/03 6/30/04
-------------------------------------------------
Fund $ 37,930 $ 27,318
Eaton Vance(1) $402,045 $299,384

(1) The Fund's investment adviser, as well as any of its affiliates that
provide ongoing services to the Fund, are subsidiaries of Eaton Vance Corp.
None of the non-audit fees listed above as billed to Eaton Vance Corp. were
for services requiring pre-approval pursuant to Rule 2-01(c)(7)(ii) of
Regulation S-X.

The Fund's Audit Committee has considered whether the provision by the
Fund's principal accountant of non-audit services to the Fund's investment
adviser, as well as any of its affiliates that provide ongoing services to the
Fund, that were not pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation
S-X is compatible with maintaining the principal accountant's independence.

OFFICERS OF THE FUND

The officers of the Fund and their length of service are set forth below.
The officers of the Fund hold indefinite terms of office. Because of their
positions with Eaton Vance and their ownership of Eaton Vance Corp. stock, the
officers of the Fund will benefit from the advisory and administration fees paid
by the Fund to Eaton Vance. As of the record date, the officers of the Fund
owned 21,019 shares of the Fund.

PROXY SOLICITATION AND TABULATION

The expense of preparing, printing and mailing this Proxy Statement and
enclosures and the costs of soliciting proxies on behalf of the Board of
Trustees of the Fund will be borne by the Fund. Proxies will be solicited by
mail and may be solicited in person or by telephone or facsimile by officers of
the Fund, by personnel of its administrator, Eaton Vance, by the transfer agent,
PFPC Inc., or by broker-dealer firms. The expenses connected with the
solicitation of these proxies and with any further proxies which may be
solicited by the Fund's officers, by Eaton Vance personnel, by the transfer
agent, PFPC Inc., or by broker-dealer firms, in person, or by telephone or by
facsimile will be borne by the Fund. A written proxy may be delivered to the
Fund or its transfer agent prior to the meeting by facsimile machine, graphic
communication equipment or similar electronic transmission. The Fund will
reimburse banks, broker-dealer firms, and other persons holding shares
registered in their names or in the names of their nominees, for their expenses
incurred in sending proxy material to and obtaining proxies from the beneficial
owners of such shares. Total estimated proxy solicitation costs are
approximately $63,000.

All proxy cards solicited by the Board of Trustees that are properly
executed and received by the Secretary prior to the meeting, and which are not
revoked, will be voted at the meeting. Shares represented by such proxies will
be voted in accordance with the instructions thereon. If no specification is
made on the proxy card with respect to Proposal 1, it will be voted for the
matters specified on the proxy card. All shares that are voted and votes to
ABSTAIN will be counted towards establishing a quorum, as will broker non-votes.
(Broker non-votes are shares for which (i) the beneficial owner has not voted
and (ii) the broker holding the shares does not have discretionary authority to
vote on the particular matter.) Accordingly, abstentions and broker non-votes
will assist the Fund in obtaining a quorum but will have no effect on the
outcome of Proposal 1.

In the event that sufficient votes by the shareholders of the Fund in favor
of any Proposal set forth in the Notice of this meeting are not received by
October 15, 2004, the persons named as attorneys in the enclosed proxy may

EATON VANCE SENIOR INCOME TRUST

August 27, 2004

EXHIBIT A

DATED AS OF JULY 16, 2004

EATON VANCE FUNDS
AUDIT COMMITTEE CHARTER

I. COMPOSITION OF THE AUDIT COMMITTEE. The Audit Committee of each registered
investment company sponsored by Eaton Vance Management (each a "Fund")
shall be comprised of at least three Trustees, each of whom shall have been
determined by the Board of Trustees to have no material relationship that
would interfere with the exercise of his or her independent judgment. No
member of the Audit Committee may be an "interested person" of a Fund as
defined in Section 2(a)(19) of the Investment Company Act of 1940, as
amended (the "1940 Act"), nor shall any member receive any compensation
from a Fund except compensation for service as a member of the Board of
Trustees or a committee of the Board. Each member of the Audit Committee
shall also satisfy the applicable Audit Committee membership requirements
imposed under the rules of the American Stock Exchange and New York Stock
Exchange (and any other national securities exchange on which a Fund's
shares are listed), as in effect from time to time, including with respect
to the member's former affiliations or employment and financial literacy.
At least one member of the Audit Committee must have the accounting or
related financial management expertise and financial sophistication
required under applicable rules of the American Stock Exchange and New York
Stock Exchange. Unless it determines that no member of the Audit Committee
qualifies as an audit committee financial expert as defined in Item 3 of
Form N-CSR, the Board of Trustees will identify one (or in its discretion,
more than one) member of the Audit Committee as an audit committee
financial expert. A Chairperson of the Audit Committee shall be appointed
by the Board of Trustees on the recommendation of the Governance Committee.

II. PURPOSES OF THE AUDIT COMMITTEE. The purposes of the Audit Committee are
to:

1. oversee each Fund's accounting and financial reporting processes, its
internal control over financial reporting, and, as appropriate, the
internal control over financial reporting of certain service
providers;

2. oversee or, as appropriate, assist Board oversight of the quality and
integrity of the Funds' financial statements and the independent audit
thereof;

3. oversee, or, as appropriate, assist Board oversight of, the Funds'
compliance with legal and regulatory requirements that relate to the
Funds' accounting and financial reporting, internal control over
financial reporting and independent audits;

4. approve prior to appointment the engagement and, when appropriate,
replacement of the independent auditors, and, if applicable, nominate
independent auditors to be proposed for shareholder ratification in
any proxy statement of a Fund;

5. evaluate the qualifications, independence and performance of the
independent auditors and the audit partner in charge of leading the
audit; and

6. prepare such audit committee reports consistent with the requirements
of Rule 306 of Regulation S-K for inclusion in the proxy statement for
the annual meeting of shareholders of a Fund.

A-1

The primary function of the Audit Committee is oversight. The Committee is
not responsible for managing the Funds or for performing tasks that are
delegated to the officers of any Fund, any investment adviser to a Fund, the
custodian of a Fund, and other service providers for the Funds, and nothing in
this charter shall be construed to reduce the responsibilities or liabilities of
management or the Funds' service providers, including the independent auditors.
It is management's responsibility to maintain appropriate systems for accounting
and internal control over financial reporting. Specifically, management is
responsible for: (1) the preparation, presentation and integrity of the
financial statements of each Fund; (2) the maintenance of appropriate accounting
and financial reporting principles and policies; and (3) the maintenance of
internal control over financial reporting and other procedures designed to
assure compliance with accounting standards and related laws and regulations.
The independent auditors are responsible for planning and carrying out an audit
consistent with applicable legal and professional standards and the terms of
their engagement letter, and shall report directly to the Audit Committee. In
performing its oversight function, the Committee shall be entitled to rely upon
advice and information that it receives in its discussions and communications
with management, the independent auditors and such experts, advisors and
professionals as may be consulted by the Committee.

III. MEETINGS OF THE AUDIT COMMITTEE. Meetings of the Audit Committee shall be
held at such times (but not less frequently than annually), at such places
and for such purposes (consistent with the purposes set forth in this
charter) as determined from time to time by the Board of Trustees, the
Committee or the Chairperson of the Committee. The Audit Committee shall
set its agenda and the places and times of its meetings. The Audit
Committee may meet alone and outside the presence of management personnel
with any auditor of a Fund, and shall periodically meet separately with
management, with internal auditors (or other personnel responsible for
internal control of financial reporting), with any independent auditors
rendering reports to the Audit Committee or the Board of Trustees and with
legal counsel. A majority of the members of the Audit Committee shall
constitute a quorum for the transaction of business at any meeting, and the
decision of a majority of the members present and voting shall determine
any matter submitted to a vote. The Audit Committee may adopt such
procedures or rules as it deems appropriate to govern its conduct under
this charter.

IV. DUTIES AND POWERS OF THE AUDIT COMMITTEE. To carry out its purposes, the
Audit Committee shall have the following duties and powers with respect to
each Fund:

1. To review and discuss with management and the independent auditors the
audited financial statements and other periodic financial statements
of the Fund (including disclosures under the item "Management's
Discussion of Fund Performance").

2. To consider the results of the examination of the Fund's financial
statements by the independent auditors, the independent auditors'
opinion with respect thereto, and any management letter issued by the
independent auditors.

3. To review and discuss with the independent auditors: (a) the scope of
audits and audit reports and the policies relating to internal
auditing procedures and controls and the accounting principles
employed in the Fund's financial reports and any proposed changes
therein; (b) the personnel, staffing, qualifications and experience of
the independent auditors; and (c) the compensation of the independent
auditors.

4. To review and assess the performance of the independent auditors and
to approve, on behalf of the Board of Trustees, the appointment and
compensation of the independent auditors. Approval by the Audit
Committee shall be in addition to any approval required under
applicable law by a majority of the members of the Board of Trustees
who are not "interested persons" of the Fund as defined in Section
2(a)(19) of the 1940 Act. In performing this function, the Committee
shall: (a) consider whether there should be a regular rotation of the
Fund's independent auditing firm; (b) discuss with the independent
auditors matters bearing upon the qualifications of such auditors as
"independent" under applicable standards of independence established
from time to time by the Securities and Exchange Commission ("SEC"),
the Public Company Accounting Oversight Board and other regulatory
authorities; and (c) shall secure from the independent auditors the
information required by Independence Standards Board Standard No. 1,
Independence Discussions with Audit Committees, as in effect from time
to time. The Audit Committee shall actively engage in a dialogue with
the independent auditors with respect to any disclosed relationships
or services that may impact the objectivity and independence of the
independent auditors.

A-2

5. To pre-approve: (a) audit and non-audit services provided by the
independent auditors to the Fund; and (b) non-audit services provided
by the independent auditors to the adviser or any other entity
controlling, controlled by or under common control with the adviser
that provides on-going services to the Fund ("Adviser Affiliates") if
the engagement of the independent auditors relates directly to the
operations and financial reporting of the Fund, as contemplated by the
Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act") and the rules
issued by the SEC in connection therewith (except, in the case of
non-audit services provided to the Fund or any Adviser Affiliate,
those within applicable DE MINIMIS statutory or regulatory
exceptions), and to consider the possible effect of providing such
services on the independence of the independent auditors.

6. To adopt, to the extent deemed appropriate by the Audit Committee,
policies and procedures for pre-approval of the audit or non-audit
services referred to above, including policies and procedures by which
the Audit Committee may delegate to one or more of its members
authority to grant such pre-approval on behalf of the Audit Committee
(subject to subsequent reporting to the Audit Committee). The Audit
Committee hereby delegates to each of its members the authority to
pre-approve any non-audit services referred to above between meetings
of the Audit Committee, provided that: (i) all reasonable efforts
shall be made to obtain such pre-approval from the Chairperson of the
Committee prior to seeking such pre-approval from any other member of
the Committee; and (ii) all such pre-approvals shall be reported to
the Audit Committee not later than the next meeting thereof.

7. To consider the controls implemented by the independent auditors and
any measures taken by management to ensure that all items requiring
pre-approval by the Audit Committee are identified and referred to the
Audit Committee in a timely fashion.

8. To receive at least annually and prior to the filing with the SEC of
the independent auditors' report on the Fund's financial statements, a
report from such independent auditors of: (i) all critical accounting
policies and practices used by the Fund (or, in connection with any
update, any changes in such accounting policies and practices), (ii)
all material alternative accounting treatments within GAAP that have
been discussed with management since the last annual report or update,
including the ramifications of the use of the alternative treatments
and the treatment preferred by the accounting firm, (iii) other
material written communications between the independent auditors and
the management of the Fund since the last annual report or update,
(iv) a description of all non-audit services provided, including fees
associated with the services, to any fund complex of which the Fund is
a part since the last annual report or update that was not subject to

A-3

the pre-approval requirements as discussed above; and (v) any other
matters of concern relating to the Fund's financial statements,
including any uncorrected misstatements (or audit differences) whose
effects management believes are immaterial, both individually and in
aggregate, to the financial statements taken as a whole. If this
information is not communicated to the Committee within 90 days prior
to the audit report's filing with the SEC, the independent auditors
will be required to provide an update, in the 90 day period prior to
the filing, of any changes to the previously reported information.

9. To review and discuss with the independent auditors the matters
required to be communicated with respect to the Fund pursuant to
Statement on Auditing Standards (SAS) No. 61 "Communication With Audit
Committees," as in effect from time to time, and to receive such other
communications or reports from the independent auditors (and
management's responses to such reports or communications) as may be
required under applicable listing standards of the national securities
exchanges on which the Fund's shares are listed, including a report
describing: (1) the internal quality-control procedures of the
independent auditors, any material issues raised by the most recent
internal quality-control review, or peer review, of the independent
auditors, or by any inquiry or investigation by governmental or
professional regulatory authorities, within the preceding five years,
respecting one or more independent audits carried out by the
independent auditors, and any steps taken to deal with any such
issues; and (2) all relationships between the independent auditors and
the Fund and any other relationships or services that may impact the
objectivity and independence of the independent auditors. To the
extent unresolved disagreements exist between management and the
independent auditors regarding the financial reporting of the Fund, it
shall be the responsibility of the Audit Committee to resolve such
disagreements.

10. To consider and review with the independent auditors any reports of
audit problems or difficulties that may have arisen in the course of
the audit, including any limitations on the scope of the audit, and
management's response thereto.

11. To establish hiring policies for employees or former employees of the
independent auditors who will serve as officers or employees of the
Fund.

12. With respect to each Fund the securities of which are listed on a
national securities exchange, to: (a) provide a recommendation to the
Board of Trustees regarding whether the audited financial statements
of the Fund should be included in the annual report to shareholders of
the Fund; and (b) to prepare an audit committee report consistent with
the requirements of Rule 306 of Regulation S-K for inclusion in the
proxy statement for the Fund's annual meeting of shareholders.

13. To discuss generally the Fund's earnings releases, as well as
financial information and guidance provided to analysts and rating
agencies, in the event a Fund issues any such releases or provides
such information or guidance. Such discussions may include the types
of information to be disclosed and the type of presentation to be
made. The Audit Committee need not discuss in advance each earnings
release or each instance in which earnings guidance may be provided.

14. To consider the Fund's major financial risk exposures and the steps
management has taken to monitor and control such exposures, including
guidelines and policies to govern the process by which risk assessment
and management is undertaken.

A-4

15. To review and report to the Board of Trustees with respect to any
material accounting, tax, valuation, or record-keeping issues which
may affect the Fund, its respective financial statements or the amount
of their dividend or distribution rates.

16. To establish procedures for: (a) the receipt, retention, and treatment
of complaints received by the Fund regarding accounting, internal
accounting controls, or auditing matters; and (b) the confidential,
anonymous submission by employees of the Fund or its service providers
(including its investment advisers, administrators, principal
underwriters and any other provider of accounting related services to
the Fund) of concerns regarding questionable accounting or auditing
matters. The Audit Committee hereby establishes the procedures set
forth in APPENDIX A hereto with respect to such matters.

17. To direct and supervise investigations with respect to the following:
(a) evidence of fraud or significant deficiencies in the design or
implementation of internal controls reported to the Committee by the
principal executive or financial officers of the Fund pursuant to the

other matters within the scope of this charter, including the
integrity of reported facts and figures, ethical conduct, and
appropriate disclosure concerning the financial statements of the
Funds.

18. To review and recommend to the Board of Trustees policies and
procedures for valuing portfolio securities of the Fund and to make

Committee by the Board of Trustees from time to time.

Committee's performance of its duties and responsibilities hereunder

Trustees for any appropriate changes or other action.

21. To report its activities to the Board of Trustees on a regular basis
and make such recommendations with respect to the above and other
matters as the Audit Committee may deem necessary or appropriate.

V. RESOURCES AND AUTHORITY OF THE AUDIT COMMITTEE. The Audit Committee shall
have the resources and authority appropriate to discharge its
responsibilities, including the authority to engage independent auditors
for special audits, reviews and other procedures and to retain special
counsel and other experts or consultants at the expense of the Funds. The

Committee necessary or appropriate in carrying out its duties under this
charter. In fulfilling its duties under this charter, the Audit Committee
shall have direct access to such officers and employees of the Funds, Eaton
Vance Management and any of its affiliated companies and the Funds' other

APPENDIX A

EATON VANCE FUNDS

AUDIT COMMITTEE COMPLAINT PROCEDURES

This policy outlines the procedures that the Audit Committee of each of the
registered investment companies sponsored by Eaton Vance Management (each, a
"Fund") shall employ with respect to complaints regarding accounting, internal
accounting controls or auditing matters concerning each of the Funds
("Complaints"). Each Employee (as defined below) shall be provided with a copy
of these procedures upon assuming his or her duties as an Employee, and annually
thereafter.

I. PROCEDURES FOR RECEIVING COMPLAINTS

All officers and employees of a Fund and, to the extent their duties relate to
accounting, internal accounting controls or auditing matters for the Fund, the
officers and employees of the Fund's investment advisers, administrators,
principal underwriters and any other provider of accounting related services to
the Fund (collectively referred to herein as "Employees"), may make complaints
anonymously and in a confidential manner as follows:

1. The complaining Employee may place a telephone call to the Chairperson
of the Audit Committee. During this phone call, the Employee should
identify the source of his or her Complaint and the practices that are
alleged to constitute an impropriety with respect to accounting,
internal auditing controls or auditing matters relating to a Fund,
providing as much detail as possible.

2. Alternatively, the Employee may submit to the Chairperson of the Audit
Committee (by hand, mail, e-mail or fax) a confidential memorandum
which details the Employee's Complaint and the practices that are
alleged to constitute an improper accounting, internal auditing
control or auditing matter, providing as much detail as possible.

3. The name and contact information for the current Chairperson of the
Audit Committee will be provided to Employees when they are provided
with a copy of these procedures.

II. PROCEDURES FOR TREATING COMPLAINTS

The Chairperson of the Audit Committee or another member of the Audit Committee
will conduct an initial evaluation of each Complaint received by the Audit
Committee as soon as reasonably practicable following receipt. In connection
with the initial evaluation the Chairperson of the Audit Committee (or such
other member of the Audit Committee) will determine whether the Complaint
actually relates to the accounting, internal accounting controls or auditing
matters of a Fund and, if not, whether it should be reviewed by a party other
than the Audit Committee. The Chairperson of the Audit Committee shall also
determine whether the Complaint requires investigation by the Audit Committee.

After the initial evaluation is complete, all Complaints requiring investigation
by the Audit Committee will be discussed at the next regularly-scheduled meeting
of the Audit Committee, or a specially-scheduled meeting in advance thereof. The
Audit Committee shall investigate the Complaints as follows:

1. the Audit Committee may choose to investigate the Complaint through
its own members and/or with the assistance of counsel;

A-6

2. the Audit Committee may select a designee within the Fund or its
service providers to investigate the Complaint, provided that the
identity of the complaining Employee shall not be disclosed to such
designee. Under no circumstances will a party who has direct
supervisory control or who may be responsible for the action giving
rise to the Complaint be charged with its investigation;

3. the Audit Committee may retain an outside party (other than the Fund's
independent auditors) to investigate the Complaint; or

4. the Audit Committee may investigate the Complaint in such other manner
determined by the Audit Committee.

Any party designated to investigate a Complaint shall be provided reasonable
access to the Fund's (and to the extent deemed necessary by the Audit Committee,
the Fund's service providers') employees, documents, and computer systems for
purposes of conducting the investigation. At the conclusion of its
investigation, which shall be completed promptly after referral of the
Complaint, the investigating party will be responsible for making a full report
to the Audit Committee with respect to the Complaint and to make recommendations
for corrective actions, if any, to be taken by the Fund. The Audit Committee
will then report to the Board of Trustees at its next regularly-scheduled
meeting with respect to the Complaint and any corrective actions recommended by
the Audit Committee. If the Complaint involves improprieties of any member of
the Board of Trustees, the Audit Committee may make its report in an executive
session of the Board of Trustees.

III. PROCEDURES FOR RETAINING COMPLAINTS

The Chairperson of the Audit Committee will be responsible for ensuring that all
Complaints received by the Audit Committee, together with any documents
pertaining to the Audit Committee (or its designee's) investigation and
treatment of the Complaint, are retained for six years, or for such longer
period as may be required by applicable law, in a manner consistent with
preserving the anonymity of Employees who have submitted Complaints.
