("CAM"), a publicly traded corporation that is controlled by John P. Calamos and the Calamos family. As of February 1, 2006, Calamos Advisors managed approximately $47 billion in assets of individuals and institutions. The Funds and Calamos Advisors may be contacted at the same address, noted above. ELECTION OF TRUSTEES Three trustees are to be elected to the board of each Fund. The nominees are Joe F. Hanauer and John E. Neal, who are currently trustees, and David D. Tripple, who was appointed to each Fund's board effective January 1, 2006. The persons named on the accompanying proxy card(s) intend to vote at the meeting (unless otherwise directed) FOR the election of those three nominees as trustees of each Fund. Currently there are eight trustees. In accordance with each Fund's Agreement and Declaration of Trust, its board of trustees is divided into three classes of approximately equal size. The terms of the trustees of the different classes are staggered. The current terms of Joe F. Hanauer and John E. Neal will expire at the annual meeting of shareholders in 2006. The terms of Nick P. Calamos and Stephen B. Timbers will expire at the annual meeting of shareholders in 2007 and the terms of John P. Calamos, Sr., Weston W. Marsh and William R. Rybak will expire at the annual meeting of shareholders in 2008. The holders of preferred shares of each Fund will have equal voting rights with the holders of common shares (i.e., one vote per share). Joe F. Hanauer, John E. Neal and David D. Tripple have been nominated for election as trustees to represent all shareholders. The vote of a plurality of the preferred shares and the common shares of each Fund, voting together as a single class, is required to elect the representatives of all shareholders. Since three trustees of each Fund are to be elected, the three persons who receive the highest number of votes at the meeting will be elected. In an uncontested election for trustees, the plurality requirement will be satisfied. The nominees for election at the 2006 annual meeting currently serve as trustees and were unanimously nominated by each board of trustees. Each trustee elected at the meeting will hold office until the 2009 annual meeting or until his successor is duly elected and qualified or 2 until his earlier resignation, retirement or removal from office. If a nominee is unable to serve because of an event not now anticipated, the persons named as proxies may vote for another person designated by the board of trustees. The following table sets forth each trustee's position(s) with each Fund, age, principal occupation during the past five years, other directorships, and the date on which he first became a trustee of the Funds. 3 NOMINEE FOR ELECTION AT THE MEETING WHO IS NOT AN INTERESTED PERSON OF ANY FUND: NUMBER OF POSITION(S) HELD WITH PORTFOLIOS IN THE FUND AND DATE FUND COMPLEX PRINCIPAL OCCUPATION(S) NAME AND AGE AT FIRST ELECTED OR OVERSEEN BY DURING PAST 5 YEARS AND FEBRUARY 1, 2006 APPOINTED TO OFFICE TRUSTEE OTHER DIRECTORSHIPS HELD Joe F.

Each Fund's board of trustees currently has four standing committees: - Executive Committee. Messrs. John Calamos, Nick Calamos and Stephen Timbers are members of each Fund's executive committee, which has authority during intervals between meetings of the board of trustees to exercise the powers of the board, with certain exceptions. - Dividend Committee. Messrs. John Calamos and Nick Calamos serve on each Fund's dividend committee. Each dividend committee is authorized to declare distributions on the respective Fund's shares in accordance with such Fund's distribution policies, including, but not limited to, regular dividends, special dividends and short- and long-term capital gains distributions. - Audit Committee. Messrs. Hanauer, Marsh, Neal, Rybak, Timbers and Tripple serve on each Fund's audit committee. The audit committees operate under a written charter, which is attached hereto as Appendix A, adopted and approved by each board. Each audit committee selects independent auditors, approves services to be rendered by the auditors, monitors the auditors' performance, reviews the results of each Fund's audit, determines whether to recommend to the board that the Fund's audited financial statements be included in the Fund's annual report and responds to other matters deemed appropriate by the boards. Each committee member is "independent" as defined by the New York Stock Exchange. Each Fund's board has determined Messrs. Neal, Rybak and Timbers to be audit committee financial experts. - Governance Committee. Messrs. Hanauer, Marsh, Neal, Rybak, Timbers and Tripple serve on each Fund's governance committee. Each committee member is "independent" as defined by the New York Stock Exchange. The governance committees operate under a written charter, which is attached hereto as Appendix B, adopted and approved by each board. Each governance committee oversees the independence and effective functioning of the board of trustees and endeavors to be informed about good practices for mutual fund boards. The governance committees also function as nominating committees by making recommendations to the boards of trustees regarding candidates for election as non-interested trustees. The governance 8 committees look to many sources for recommendations of qualified trustees, including current trustees, employees of Calamos Advisors, current shareholders of the Funds, search firms that are compensated for their services and other third party sources. Search firms that are retained by the governance committees to identify potential candidates evaluate potential candidates, conduct screening interviews and provide information to the governance committees with respect to the individual candidates and the market for available candidates. In making trustee recommendations, the governance committees consider a number of factors, including a candidate's background, integrity, knowledge and relevant experience. These factors are set forth in an appendix to the committees' charter. Any prospective candidate is interviewed by the Funds' trustees and officers, and references are checked. The governance committees will consider shareholder recommendations regarding potential trustee candidates that are properly submitted to the governance committees for their consideration. A shareholder of a Fund who wishes to propose a trustee candidate must submit any such recommendation in writing via regular mail to the attention of the Fund's Secretary, at the address of the Fund's principal executive offices. The shareholder recommendation must include: - the number and class of all Fund shares owned beneficially or of record by the nominating shareholder at the time the recommendation is submitted and the dates on which such shares were acquired, specifying the number of shares owned beneficially; - a full listing of the proposed candidate's education, experience (including knowledge of the investment company industry, experience as a director or senior officer of public or private companies, and directorships on other boards of other registered investment companies), current employment, date of birth, business and residence address, and the names and addresses of at least three professional references; - information as to whether the candidate is, has been or may be an "interested person" (as such term is defined in the 1940 Act) of the Funds, Calamos Advisors or any of its affiliates, and, if believed not to be or have been an "interested person," information regarding the candidate that will be sufficient for the committee to make such determination; 9 - the written and signed consent of the candidate to be named as a nominee and to serve as a trustee of the Funds, if elected; - a description of all arrangements or understandings between the nominating shareholder, the candidate and/or any other person or persons (including their names) pursuant to which the shareholder recommendation is being made, and if none, so specify; - the class or series and number of all shares of the Funds owned of record or beneficially by the candidate, as reported by the candidate; and - such other information that would be helpful to the governance committees in evaluating the candidate. The governance committees may require the nominating shareholder to furnish other information they may reasonably require or deem necessary to verify any information furnished pursuant to the procedures delineated above or to determine the qualifications and eligibility of the candidate proposed by the nominating shareholder to serve as a trustee. If the nominating shareholder fails to provide such additional information in writing within seven days of receipt of written request from the governance committees, the recommendation of such candidate will be deemed not properly submitted for consideration, and the governance committees are not required to consider such candidate. Unless otherwise specified by the governance committees' chairman or by legal counsel to the non-interested trustees, the Funds' Secretary will promptly forward all shareholder recommendations to the governance committees' chairman and the legal counsel to the non-interested trustees, indicating whether the shareholder recommendation has been properly submitted pursuant to the procedures adopted by the governance committees for the consideration of trustee candidates nominated by shareholders. Recommendations for candidates as trustees will be evaluated, among other things, in light of whether the number of trustees is expected to change and whether the trustees expect any vacancies. During periods when the governance committees are not actively recruiting new trustees, shareholder recommendations will be kept on file until active recruitment is under way. After consideration of a shareholder recommendation the governance committees may dispose of the shareholder recommendation. 10 In addition to the above committees, each Fund's board of trustees has appointed and oversees a pricing committee comprised of officers of the Fund and employees of Calamos Advisors. The following table shows the number of meetings held for each Fund during the fiscal year ended October 31, 2005: CHI CHY CSQ CGO Board of Trustees 5 5 5 5 Executive Committee* 0 0 0 0 Audit Committee 4 4 4 4 Governance Committee 3 3 3 3 Dividend Committee** 0 0 0 0 * Although the executive committees of CHI, CHY, CSQ and CGO held no meetings, they acted by written consent on 9, 7, 5 and 1 occasions, respectively. ** Although the dividend committees of CHI, CHY, CSQ and CGO held no meetings, they acted by written consent on 6, 6, 6 and 0 occasions, respectively. Each of the trustees and committee members then serving attended at least 75% of the meetings of the board of trustees and applicable committees held during the fiscal year, except for Nick Calamos, who attended 60% of the meetings held by the board of trustees. TRUSTEE COMPENSATION. The Funds do not compensate any of the trustees who are affiliated persons of Calamos Advisors. The following table sets forth certain information with respect to the compensation paid by the Funds and the Fund Complex during the fiscal year ended October 31, 2005 to each of the current trustees.

Tripple** na na na na na + Includes fees deferred during the year pursuant to the deferred compensation plan described below. As of October 31, 2005, the values of Messrs. Neal's and Marsh's deferred compensation accounts were $226,108 and $89,063, respectively. * The Fund Complex includes Calamos Investment Trust, Calamos Advisors Trust and the Funds. ** Appointed trustee effective January 1, 2006. 11 The Funds have adopted a deferred compensation plan (the "Plan"). Under the Plan, a trustee who is not an "interested person" of Calamos Advisors who has elected to participate in the Plan ("participating trustees") may defer receipt of all or a portion of his compensation from the Funds. The deferred compensation payable to the participating trustee is credited to the participating trustee's deferral account as of the business day such compensation would have been paid to the participating trustee. The value of a participating trustee's deferred compensation account at any time is equal to what would be the value if the amounts credited to the account had instead been invested in shares of one or more of the funds of Calamos Investment Trust as designated by the participating trustee. Thus, the value of the account increases with contributions to the account or with increases in the value of the measuring shares, and the value of the account decreases with withdrawals from the account or with declines in the value of the measuring shares. If a participating trustee retires, the participating trustee may elect to receive payments under the plan in a lump sum or in equal annual installments over a period of five years. If a participating trustee dies, any amount payable under the Plan will be paid to the participating trustee's beneficiaries. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS. The Funds have entered into Investment Management Agreements and a Financial Accounting Services Agreement with Calamos Advisors. Calamos Advisors is indirectly owned by Messrs. John Calamos and Nick Calamos, who serve as trustees of the Funds. According to the terms of the Investment Management Agreements, Calamos Advisors provides portfolio management services to the Funds in consideration for fees based on the Funds' average weekly managed assets. According to the terms of the Financial Accounting Services Agreement, Calamos Advisors provides certain accounting services to the Funds in consideration for fees based on the Funds' daily average net assets. REQUIRED VOTE. The trustees of a Fund will be elected by the vote of a plurality of all shares of the Fund present at the meeting, in person or by proxy. Each share is entitled to one vote, and one-third of the shares of each Fund entitled to vote is a quorum for that Fund. BOARD RECOMMENDATION EACH FUND'S BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT EACH FUND'S SHAREHOLDERS VOTE "FOR" THE NOMINEES. 12 OTHER MATTERS Each Fund's board of trustees knows of no other matters that are intended to be brought before the meeting. If other matters are presented for action, the proxies named in the enclosed form of proxy will vote on those matters in their sole discretion. MORE INFORMATION ABOUT THE MEETING SHAREHOLDERS.

All proxies solicited by the board of trustees that are properly executed and received prior to the meeting, and that are not revoked, will be voted at the meeting. Shares represented by those proxies will be voted in accordance with the instructions marked on the proxy. If no instructions are specified, shares will not be counted as a vote FOR the proposal. HOW TO VOTE. Complete, sign and date the enclosed proxy card and return it in the enclosed envelope. EXPENSES. The expenses of preparing, printing and mailing the enclosed proxy card, the accompanying notice and this proxy statement 17 and all other costs, in connection with the solicitation of proxies will be borne by the Funds. The Funds may also reimburse banks, brokers and others for their reasonable expenses in forwarding proxy solicitation material to the beneficial owners of shares of the Funds. In order to obtain the necessary quorum at the meeting, additional solicitation may be made by mail, telephone, telegraph, facsimile or personal interview by representatives of the Funds, Calamos Advisors, the Funds' transfer agent, or by brokers or their representatives or by a solicitation firm that may be engaged by the Funds to assist in proxy solicitations. Any costs associated with such additional solicitation are not anticipated to be significant. HOUSEHOLDING. The Funds reduce the number of duplicate shareholder reports and proxy statements your household receives by sending only one copy of those documents to those addresses shared by two or more accounts. Call the Funds at 1-800-582-6959 or write to the Funds at the address on page one of this proxy statement to request individual copies of shareholder reports and proxy statements, or to request a single copy of shareholder reports and proxy statements if your household is receiving duplicate copies. We will begin sending your household single or multiple copies, as you request, as soon as practicable after receiving your request. REVOKING A PROXY. At any time before it has been voted, you may revoke your proxy by: (1) sending a letter saying that you are revoking your proxy to the Secretary of the Funds at the Funds' offices located at 2020 Calamos Court, Naperville, Illinois 60563-2787; (2) properly executing and sending a later-dated proxy; or (3) attending the meeting, requesting return of any previously delivered proxy, and voting in person. QUORUM, VOTING AT THE MEETING, AND ADJOURNMENT. One-third of the shares of each Fund entitled to vote, present in person or represented by proxy, constitutes a quorum for electing trustees of that Fund. For purposes of determining the presence or absence of a quorum and for determining whether sufficient votes have been received for approval of any matter to be acted upon at the meeting, abstentions and broker nonvotes will be treated as shares that are present at the meeting but have not been voted. If a quorum is not present in person or by proxy at the meeting, or if a quorum is present at the meeting but not enough votes to approve a proposal are received, the persons named as proxies may propose one or more adjournments of the meeting to permit further 18 solicitation of proxies. Any proposal for adjournment for a Fund will require the vote of a majority of the shares of the Fund represented at the meeting in person or by proxy. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 30(h) of the 1940 Act and Section 16(a) of the Securities Exchange Act of 1934 require the Funds' trustees and officers, investment adviser, affiliated persons of the investment adviser and persons who own more than 10% of a registered class of the Funds' equity securities to file forms reporting their affiliation with the Fund(s) and reports of ownership and changes in ownership of the Funds' shares with the Securities and Exchange Commission (the "SEC") and the New York Stock Exchange. Those persons and entities are required by SEC regulation to furnish the Funds with copies of all Section 16(a) forms they file. Based on a review of those forms furnished to the Funds, each Fund believes that its trustees and officers, investment adviser and affiliated persons of the investment adviser have complied with all applicable Section 16(a) filing requirements, except that Mark Mickey was late in filing Forms 3 for Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund and Calamos Strategic Total Return Fund and in filing a Form 4 for Calamos Convertible and High Income Fund and Stephen Timbers was late in filing Forms 3 for Calamos Opportunities and Income Fund and Calamos Convertible and High Income Fund. In addition, Calamos Advisors was late in filing its initial report of ownership for Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund and Calamos Strategic Total Return Fund resulting from a reorganization with a predecessor, which predecessor previously reported its ownership of such Funds. To the knowledge of each Fund's management, for purposes of Section 16(a) reporting, no person owns beneficially more than 10% of a class of any Fund's equity securities. AUDIT COMMITTEE REPORT The audit committee of each Fund's board of trustees reviews that Fund's annual financial statements with both management and the independent auditors, and the committee meets periodically with the independent and internal auditors to consider their evaluation of the Fund's financial and internal controls. 19 Each audit committee, in discharging its duties, has met with and held discussions with management and the Fund's independent and internal auditors. The committees have reviewed and discussed the audited financial statements with management. Management has represented to the independent auditors that each Fund's financial statements were prepared in accordance with generally accepted accounting principles. The audit committees have also discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61 (Communications with Audit Committees). The independent auditors provided to the committees the written disclosure required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), and the committees discussed with representatives of the independent auditors their firm's independence. Based on each audit committee's review and discussions with management and the independent auditors, the representations of management and the reports of the independent auditors to the committees, each committee recommended that the respective board include the audited financial statements in the Fund's annual report. The members of the audit committee are: Joe F. Hanauer, Weston W. Marsh, John E. Neal, William R. Rybak, Stephen B. Timbers and David D. Tripple. INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Each Fund's audit committee selected Deloitte & Touche LLP ("D&T") as the independent registered public accounting firm to audit the books and records of that Fund for its fiscal year ending October 31, 2005.

There were no fees billed in either of the last two fiscal years for products and services provided by D&T to Calamos Advisors or any entity controlling, controlled by or under common control with Calamos Advisors that were required to be pre-approved by any of the Funds' audit committees. 21 AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES. Each Fund's audit committee meets with D&T and Calamos Advisors to review and pre-approve all audit services to be provided by D&T. Each audit committee shall pre-approve all non-audit services to be provided by D&T to the respective Fund, including the fees and other compensation to be paid to D&T; provided that the pre-approval of non-audit services is waived if (i) the services were not recognized by management at the time of the engagement as non-audit services, (ii) the aggregate fees for all non-audit services provided to the relevant Fund are less than 5% of the total fees paid by such Fund to D&T during the fiscal year in which the non-audit services are provided, and (iii) such services are promptly brought to the attention of the audit committee by Calamos Advisors and such audit committee approves them prior to the completion of the audit. Each audit committee shall pre-approve all non-audit services to be provided by D&T to Calamos Advisors or any entity controlling, controlled by or under common control with Calamos Advisors that provides ongoing services to the respective Fund if the engagement relates directly to the operations or financial reporting of the Fund, including the fees and other compensation to be paid to D&T; provided that pre-approval of non-audit services to Calamos Advisors or any of its affiliates is not required if (i) the services were not recognized by Calamos Advisors at the time of the engagement as non-audit services, (ii) the aggregate fees for all non-audit services provided to Calamos Advisors and all entities controlling, controlled by or under common control with Calamos Advisors are less than 5% of the total fees for non-audit services requiring pre-approval paid by the Fund, Calamos Advisors or its affiliates to D&T during the fiscal year in which the non-audit services are provided, and (iii) such services are promptly brought to the attention of the relevant audit committee by Calamos Advisors and the audit committee approves them prior to the completion of the audit. One hundred percent of the services provided to each Fund described under the paragraphs entitled Audit-Related Fees, Tax Fees and All Other Fees were pre-approved by the relevant Fund's audit committees. There were no services provided to Calamos Advisors or any entity controlling, controlled by or under common control with Calamos Advisors described in the paragraphs entitled Audit-Related Fees, Tax Fees and All Other Fees that were required pre-approved by the audit committees. 22 AGGREGATE NON-AUDIT FEES. D&T billed CHI, CHY, CSQ and CGO aggregate fees in the amounts of $40,392, $47,008, $106,698 and $2,000, respectively, for the fiscal year ended October 31, 2005 and $13,579, $13,579, $7,167 and $0, respectively, for the fiscal year ended October 31, 2004 for non-audit services.

The Funds' audit committees approved such non-audit services. Each Fund's audit committee has considered whether D&T's provision of services (other than audit services to each Fund) to the Fund, Calamos Advisors and affiliates of Calamos Advisors that provide services to the Fund is compatible with maintaining D&T's independence in performing audit services. ADMINISTRATOR Each Fund has entered into an administration agreement with State Street Bank and Trust Company whose principal business address is 225 Franklin Street, Boston, Massachusetts 02110. SHAREHOLDER COMMUNICATIONS Shareholders are able to send communications to the Funds' governance committees. Communications should be addressed to the Secretary of the Funds at their principal offices at 2020 Calamos Court, Naperville, Illinois 60563-2787. The Secretary will forward any communications received directly to the governance committees. The Funds do not have a policy with regard to trustee attendance at annual meetings. All of the trustees of the Funds attended the 2005 annual meeting. SHAREHOLDER PROPOSALS A shareholder proposal for consideration at the 2007 annual meeting of a Fund should be submitted in writing pursuant to Rule 14a-8 of the Securities Exchange Act of 1934 to the Secretary of the Fund at 2020 Calamos Court, Naperville, Illinois 60563-2787, not later than November 9, 2006.

Timely submission of a proposal does not mean the proposal will be included in the proxy material sent to shareholders. By Order of the Board of Trustees of each Fund, James S. Hamman, Jr. Secretary February 24, 2006 24 Appendix A CALAMOS INVESTMENT TRUST CALAMOS ADVISORS TRUST CALAMOS CONVERTIBLE OPPORTUNITIES AND INCOME FUND CALAMOS CONVERTIBLE AND HIGH INCOME FUND CALAMOS STRATEGIC TOTAL RETURN FUND CALAMOS GLOBAL TOTAL RETURN FUND AUDIT COMMITTEE CHARTER (adopted by the Boards of Trustees on October 7, 2005) I. PURPOSES The Audit Committee (the "Committee") is a committee of the Board of Trustees (the "Board") of each of the trusts and funds named above (each referred to as a "Trust"). Its purposes are to: A. Oversee the Trust's accounting and financial reporting policies and practices, its internal controls over financial reporting and, as appropriate in its judgment, the internal controls of certain service providers; B. Assist Board oversight of (i) the integrity of the Trust's financial statements, (ii) the Trust's compliance with legal and regulatory requirements, (iii) the independent auditors' qualifications and independence, and (iv) the performance of the independent auditors; C. Pre-approve the audit and non-audit services that the Trust's independent auditors provide to the Trust and certain non-audit services that the Trust's independent auditors may provide to the Trust's investment adviser (the "Adviser") and its affiliates; D. Prepare a Committee report as required by the SEC to be included in the annual proxy statement of any closed-end Trust; and E. Act as a liaison between the Trust's independent auditors and the Board. 25 The function of the Committee is oversight. It is the responsibility of management and the Trust's service providers to maintain appropriate systems for accounting and internal control, and the independent auditors' responsibility to plan and carry out proper audits. In fulfilling their responsibilities as members of the Committee, it is recognized that members of the Committee are not full-time employees of the Trust or the Adviser and are not, and do not represent themselves to be, performing the functions of auditors or accountants. As such, it is not the duty or responsibility of the Committee or its members to conduct field work or other types of auditing or accounting reviews or procedures or to set auditor independence standards, and each member of the Committee shall be entitled to rely on (i) the integrity of those persons and organizations within and outside the Trust or the Adviser from which it receives information, (ii) the accuracy of financial and other information provided to the Committee by such persons or organizations absent actual knowledge to the contrary (which shall be promptly reported to the Board) and (iii) representations made by management and the Trust's service providers as to any information technology, internal audit or other non-audit services provided by the Trust's auditors, the Adviser, the distributor, the custodian, any other Trust service provider or any entity in a control relationship with the Trust or the Adviser. II. ORGANIZATION AND COMPOSITION This charter has been adopted by the Board of each Trust. The members of the Committee of each Board shall be appointed annually by such Board, which shall also designate a chair of the Committee. Members of the Committee shall serve at the pleasure of the Board. The Committee shall be comprised of three or more Board members, each of whom the Board has determined to be: (a) not an "interested person" of the Trust, as defined in the Investment Company Act of 1940, as amended (the "Investment Company Act"), (b) free of any relationship with the management of the Trust or the Adviser, distributor or custodian, that, in the opinion of the Board, would interfere with the member's exercise of independent judgment as a Committee member, (c) in compliance with the independence requirements of the Sarbanes-Oxley Act of 2002 and the rules of the Securities and Exchange Commission (the "SEC") adopted thereunder, and (d) for closed-end Trusts only, meet the independence requirements set forth in New York Stock Exchange listing standards. 26 If a Committee member serves on the audit committees of more than three public companies, the Board must determine that such simultaneous service would not impair the ability of such member to effectively serve on the Committee. The Board, in its business judgment, shall determine that each member of the Committee is financially literate (or, in the case of a member who was not financially literate at the time of appointment to the Committee, is expected to become financially literate within a reasonable time thereafter) and whether any member is an "audit committee financial expert," as defined by the SEC. At least one member shall have accounting or related financial management expertise, as the Board interprets such qualification in its business judgment. Committee members may enhance their familiarity with finance and accounting by participating in educational programs from time to time, at the expense of the Trust. III. MEETINGS The Committee shall meet four times annually, or more frequently if required. The presence in person or by telephone of a majority of the Committee members shall constitute a quorum at any meeting. IV. RESPONSIBILITIES The Committee shall: A. WITH RESPECT TO THE INDEPENDENT AUDITORS. 1. Consistent with the requirements of the Investment Company Act and relevant state law, have the ultimate authority and responsibility to select (or to nominate the independent auditors to be proposed for shareholder approval in any proxy statement), evaluate and, where appropriate, replace the independent auditors; review the auditors' fees to determine whether such fees appear to be appropriate for the services rendered; and, review and evaluate the lead audit partner of the independent auditor and confirm the required rotation of all "audit partners" (as such term is defined by the SEC). 2.
