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 12, 2007, 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, 2007. The Board of Trustees of the Fund has fixed the close of business on August 16, 2007 as the record date for the determination of the shareholders entitled to notice of and to vote at the meeting and any adjournments or postponements thereof. Shareholders at the close of business on the record date will be entitled to one vote for each share held. As of August 16, 2007, there were [36,466,497] Common Shares of beneficial interest, $.01 par value per share (“Common Shares”), and 4,400 Auction Preferred Shares, $.01 par 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 of the Fund; and (ii) the Trustees and executive officers of the Fund, individually and as a group, beneficially owned 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 Agreement and 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 will fix the appropriate number of Trustees from time to time. The Fund’s Agreement and 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 2007 Annual Meeting, and the term of office of the Class I and Class II Trustees will expire one and two years thereafter, respectively. Accordingly, nominees for three Class III Trustees are currently proposed for election. In addition, the Board has nominated Thomas E. Faust Jr., who was appointed by the Board as a Class I Trustee effective April 23, 2007, for election as a Class I Trustee and Allen R. Freedman, who was appointed by the Board as a Class II Trustee effective April 23, 2007, for election as a Class II Trustee. Trustees chosen to succeed the Trustees whose terms are expiring will be elected for a three-year term except for Messrs. Faust and Freedman who will be elected to serve until 2008 and 2009, respectively, to coincide with the term of office of their respective Class. 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: Heidi L. Steiger, Lynn A. Stout and William H. Park; for the following Class I Trustee nominee: Thomas E. Faust Jr.; and for the following Class II nominee: Allen R. Freedman. Mr. Faust, Mr. Freedman and Ms. Steiger were appointed Trustees of the Fund by the Board of Trustees effective April 23, 2007. 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. No nominee is a party adverse to the Fund or any of its affiliates in any material pending legal proceeding, nor does any nominee have an interest materially adverse to the Fund.

The Class I Trustees serving until the 2008 Annual Meeting are Benjamin C. Esty, Thomas E. Faust Jr., James B. Hawkes and Ronald A. Pearlman. The Class II Trustees serving until the 2009 Annual meeting are Allan R. Freedman, Norton H. Reamer and Ralph F. Verni.

The three Class III Trustee nominees, one Class I Trustee nominee and one Class II Trustee nominee and the Fund’s current remaining Class I and Class II Trustees and their principal occupations for at least the last five years are as described below.

Interested Trustees

Thomas E. Faust Jr. and James B. Hawkes are “interested persons” (as defined in the Investment Company Act of 1940 (the “1940 Act”)) by reason of their affiliations with EVM, the Fund’s investment adviser, and EVC, a publicly-held holding company, which owns all the outstanding shares of EVM and of EVM’s trustee, EV. (EVM, EVC, and their affiliates are sometimes referred to collectively as the “Eaton Vance Organization”.) Messrs. Faust and Hawkes hold positions with other Eaton Vance affiliates that are comparable to their position with Eaton Vance listed above.

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 APS. 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. Shareholders do not have appraisal rights in connection with the proposal in this proxy statement. The Trustees of the Fund shall be elected by the affirmative vote of 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, 2007, 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 five times, the Special Committee met eleven times and the Governance Committee met eight times during such period. Each Trustee attended at least 75% of the Board and Committee meetings on which he or she serves. None of the Trustees attended the Fund’s 2006 Annual Meeting of Shareholders.

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), Park and Verni, and Mmes. Steiger and Stout serve on the Audit Committee of the Board of Trustees of the Fund, such Audit Committee being established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934. Each Audit Committee member is independent under applicable 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 processes, its internal control over financial reporting, and, as appropriate, the internal control over financial reporting of certain service providers; (ii) oversee or, as appropriate, assist Board oversight of the quality and integrity of the Fund’s financial statements and the independent audit thereof; (iii) oversee, or, as appropriate, assist Board oversight of, the Fund’s compliance with legal and regulatory requirements that relate to the Fund’s accounting and financial reporting, internal control over financial reporting and independent audits; (iv) 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 the Fund; (v) evaluate the qualifications, independence and performance of the independent auditors and the audit partner in charge of leading the audit; and (vi) 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 the Fund. The Fund’s Board of Trustees has adopted a written charter for its Audit Committee, a copy of which, without appendices, 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 and Reamer as the Fund’s Audit Committee financial experts.

Messrs. Verni (Chair), Esty, Freedman, 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.

Mmes. Stout (Chair) and Steiger, and Messrs. Esty, Freedman, Park, Pearlman, Reamer and Verni serve on the Governance Committee of the Board of Trustees of the Fund. Each Governance Committee member is independent under applicable listing standards of the New York Stock Exchange. 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 a Chairperson of the Board 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 but is not available on Eaton Vance’s website. The Governance Committee identifies candidates by obtaining referrals from such sources as it deems appropriate, which may include current Trustees, management of the Fund, counsel and other advisors to the Trustees, and shareholders of the Fund who submit recommendations in accordance with the procedures described in the Committee’s charter. In no event shall the Governance Committee consider as a candidate to fill any vacancy an individual recommended by management of the Fund, unless the Governance Committee has invited management to make such a recommendation. The Governance Committee will, when a vacancy exists or is anticipated, consider any nominee for Independent Trustee recommended by a shareholder if such recommendation is submitted in writing to the Governance Committee, contains sufficient background information concerning the candidate, including evidence the candidate is willing to serve as an Independent Trustee if selected for the position, and is received in a sufficiently timely manner. 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 and the qualifications the Governance Committee will consider, 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 Board, the Chairperson of any 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, 2007, the noninterested Trustees of the Fund earned the compensation set forth below in their capacities as Trustees of the Fund. For the calendar year ended December 31, 2006, the Trustees earned the compensation set forth below in their capacities as Trustees of the funds in the Eaton Vance fund complex⁽¹⁾:

		Total Compensation From Fund and Fund Complex
	Aggregate Compensation from Fund

Name of Trustee

Benjamin C. Esty	$2,306	$185,000

(1)		As of August 16, 2007, the Eaton Vance Fund Complex consisted of 177 registered investment companies or series thereof.
(2)		Mr. Freedman and Ms. Steiger were appointed as Trustees of the Fund effective April 23, 2007 and thus did not receive
		compensation from the Eaton Vance Fund Complex during the calendar year ended December 31, 2006.
(3)		Includes $1,408 of deferred compensation.
(4)		Includes $133,680 of deferred compensation.
(5)		Includes $649 of deferred compensation.
(6)		Includes $45,000 of deferred compensation.
(7)		Includes $1,495 of deferred compensation.
(8)		Includes $92,500 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 or her 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 three Class III Trustee nominees, one Class I Trustee nominee and one Class II Trustee nominee.

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., P.O. Box 43027, Providence, RI 02940-3027.

ADDITIONAL INFORMATION

Audit Committee Report

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 independent registered public accounting firm.

The following table presents (i) the aggregate non-audit fees (i.e., fees for audit-related, tax, and other services) billed for services rendered to the Fund by the Fund’s independent registered public accounting firm for the Fund’s two fiscal years ended June 30, 2006 and 2007; 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 independent registered public accounting firm for the two fiscal years ended June 30, 2006 and June 30, 2007.

Fiscal Year Ended	6/30/06	6/30/07

Fund	$29,100	$18,534
Eaton Vance⁽¹⁾	$35,600	$78,500

⁽¹⁾		The Fund’s investment adviser and any of its affiliates that provide ongoing services to the Fund are subsidiaries of Eaton Vance Corp.

The Fund’s Audit Committee has considered whether the provision by the Fund’s independent registered public accounting firm 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 independent registered public accounting firm’s independence.

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 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 $53,000.

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, which will be treated as shares that are present at the meeting but which have not been voted, will assist the Fund in obtaining a quorum, but will have no effect on the outcome of Proposal 1.

In the event that a quorum is not present at the meeting, or if a quorum is present at the meeting but sufficient votes by the shareholders of the Fund in favor of the Proposal set forth in the Notice of this meeting are not received by October 12, 2007, the persons named as attorneys in the enclosed proxy may propose one or more adjournments of the meeting to permit further solicitation of proxies. Any such adjournment will require the affirmative vote of the holders of a majority of the shares present in person or by proxy at the session of the meeting to be adjourned. The persons named as attorneys in the enclosed proxy will vote in favor of such adjournment those proxies which they are entitled to vote in favor of the Proposal for which further solicitation of proxies is to be made. They will vote against any such adjournment those proxies required to be voted against such Proposal. The costs of any such additional solicitation and of any adjourned session will be borne by the Fund. If any of the nominees are not elected by shareholders, the current Trustees may consider other courses of action.

Section 16(a) Beneficial Ownership Reporting Compliance

Based solely upon a review of the copies of the forms received by the Fund, all of the Trustees and officers of the Fund, EVM and its affiliates, and any person who owns more than ten percent of the Fund’s outstanding securities have made all filings required under Section 16(a) of the Securities Exchange Act of 1934 regarding ownership of shares of the Fund for the Fund’s fiscal year ended June 30, 2007.

The Fund will furnish without charge a copy of its most recent Annual and Semiannual Reports to any shareholder upon request. Shareholders desiring to obtain a copy of such reports should write to the Fund c/o PFPC Inc., P.O. Box 43027, Providence, RI 02940-3027, or call 1-800-331-1710.

SHAREHOLDER PROPOSALS

To be considered for presentation at the Fund’s 2008 Annual Meeting of Shareholders, a shareholder proposal submitted pursuant to Rule 14a-8 under the Securities Exchange Act of 1934 must be received at the Fund’s principal office c/o the Secretary of the Fund no later than the close of business April 30, 2008. Written notice of a shareholder proposal submitted outside of the processes of Rule 14a-8 must be delivered to the Fund’s principal office c/o the Secretary of the Fund no later than the close of business July 15, 2008 and no earlier than June 13, 2008. In order to be included in the Fund’s proxy statement and form of proxy, a shareholder proposal must comply with all applicable legal requirements. Timely submission of a proposal does not guarantee that such proposal will be included.

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 of the Board. All members of the Audit Committee shall be Trustees who are not “interested persons” (as defined under the Investment Company Act of 1940, as amended ) of any Fund or of the investment adviser or sub-adviser of any Fund (each, an “Independent Trustee” and collectively, the “Independent Trustees”). The members of the Audit Committee shall consist of the Chairperson of the Board of Trustees and such other Independent Trustees as may be appointed by the Board, which shall also determine the number and term of such members.

	Each member of the Audit Committee 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 shall receive any compensation from a Fund except compensation for service as a member or Chairperson of the Board of Trustees or of 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 registered public accountants (“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

A-1

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.

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 Chairperson of 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 meet to review and discuss with management and the independent auditors the audited financial statements and other periodic financial statements of the Fund (including the Fund’s specific 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.

A-2

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.

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

A-3

	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 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.

A-4

	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.

	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 requirements of the Sarbanes-Oxley Act and related rules; and (b) any 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.

PROCEDURES WITH RESPECT TO NOMINEES TO THE BOARD



I.	Identification of Candidates. When a vacancy on the Board of a Fund exists or is anticipated, and such vacancy is to be filled by an Independent Trustee, the Governance Committee shall identify candidates by obtaining referrals from such sources as it may deem appropriate, which may include current Trustees, management of the Funds, counsel and other advisors to the Trustees, and shareholders of a Fund who submit recommendations in accordance with these procedures. In no event shall the Governance Committee consider as a candidate to fill any such vacancy an individual recommended by management of the Funds, unless the Governance Committee has invited management to make such a recommendation.

II.	Shareholder Candidates. The Governance Committee shall, when identifying candidates for the position of Independent Trustee, consider any such candidate recommended by a shareholder of a Fund if such recommendation contains (i) sufficient background information concerning the candidate, including evidence the candidate is willing to serve as an Independent Trustee if selected for the position; and (ii) is received in a sufficiently timely manner (and in any event no later than the date specified for receipt of shareholder proposals in any applicable proxy statement with respect to a Fund).
