The Boards believe that each Trustee's experience, qualifications, attributes and skills on an individual basis and in combination with those of other Trustees lead to the conclusion that each Trustee should serve in such capacity. Among the attributes or skills common to all Trustees are their ability to review critically and to evaluate, question and discuss information provided to them, to interact effectively with the other Trustees, the Fund's investment adviser, the administrator and other service providers, counsel and independent registered public accounting firm, and to exercise effective and independent business judgment in the performance of their duties as Trustees. Each Trustee's ability to perform the duties of a trustee effectively has been attained and enhanced through the Trustee's education, professional training and other life experiences, such as business, consulting or public service positions and through experience from service as a member of HQH, HQL and THQ's Boards, public companies, or non-profit entities or other organizations.

The following table sets forth, for each Trustee, the aggregate dollar range of equity securities owned by such Trustee in HQH, HQL and THQ and in the aggregate in HQH, HQL and THQ as of March 31, 2015. The information as to beneficial ownership is based upon statements furnished by each Trustee.

Although Trustees are encouraged to attend the annual meetings of shareholders to the extent they are able, none of the Funds has a formal policy with regard to Board members' attendance at annual meetings of shareholders. Last year, four Trustees then in office attended the annual meeting of shareholders of HQH and HQL.

Shareholders wishing to send communications to the Board of any Fund may communicate with members of the Board by submitting a written communication directed to the Board in care of the Fund's President, Daniel R. Omstead, Ph.D., at 100 Federal Street, 19th Floor, Boston, MA 02110.

Trustees – Leadership Structure and Oversight Responsibilities

Overall responsibility for general oversight of each Fund rests with the Board. The Board of each Fund is comprised of seven individuals, six of whom are not "interested persons" of the Fund as defined in the 1940 Act ("Independent Trustees"). The Chairman of the Board is an Independent Trustee. The Chairman presides at meetings of the Trustees, participates in the preparation of the agenda for meetings of the Board, and acts as a liaison between the Independent Trustees and the Fund's management between Board meetings. Except for any duties specified herein, the designation as Chairman does not impose any obligations or standards greater than or different from other Trustees.

The Board of each Fund holds regular quarterly meetings each year to consider and address matters involving the Fund. The Board also may hold special meetings to address matters arising between regular meetings. The Independent Trustees also meet outside the presence of management in executive session at least quarterly and have engaged independent legal counsel to assist them in performing their oversight responsibilities.

The Board of each Fund has established Audit, Governance and Nominating, Valuation and Qualified Legal Compliance Committees to assist the Board in the oversight of the management and affairs of the Fund. All of the members of these Committees are Independent Trustees, except for Dr. Omstead, who serves on the Valuation Committee. From time to time the Board may establish additional committees or informal working groups to deal with specific matters.

Each Fund is subject to a number of risks including investment, compliance, operational and valuation risks. Although the Adviser and the officers of each Fund are responsible for managing these risks on a day-to-day basis, the Board of each Fund has adopted, and periodically reviews, policies and procedures designed to address these risks. As part of its regular oversight, the Board of each Fund, directly or through a Committee, interacts with the Fund's Chief Compliance Officer, the Fund's independent public accounting firm, and the Fund's legal counsel. These interactions include discussing the Fund's risk management and controls with the independent registered public accounting firm engaged by the Fund, reviewing valuation policies and procedures and the valuations of specific restricted securities, and receiving periodic reports from the Fund's Chief Compliance Officer regarding compliance matters relating to the Fund and its major service providers, including results of the implementation and testing of the Fund's and such providers' compliance programs. The Board's oversight function is facilitated by management reporting processes designed to provide information to the Board regarding the identification, assessment, and management of critical risks and the controls and policies and procedures used to mitigate those risks. The Board reviews its role in supervising the Fund's risk management from time to time and may change the manner in which it fulfills its oversight responsibilities at its discretion at any time.

The Board of each Fund has determined that its leadership structure is appropriate for the Fund because it enables the Board to exercise informed and independent judgment over matters under its purview, allocates responsibility among committees in a manner that fosters effective oversight and allows the Board to devote appropriate resources to specific issues in a flexible manner as they arise. The Board periodically reviews its leadership structure as well as its overall structure, composition, and functioning and may make changes at its discretion at any time.

Standing Committees

Audit Committee. Each Fund has an Audit Committee comprised solely of Independent Trustees who are "independent" as defined in the New York Stock Exchange ("NYSE") Listing Standards. The Board of each Fund has adopted a written charter for the Audit Committee. The Audit Committee charter is available at http://www.teklacap.com/hqh-reports.html. The principal purpose of each Fund's Audit Committee is to assist the Board in fulfilling its responsibility to oversee management's conduct of the Fund's financial reporting process, including reviewing the financial reports and other financial information provided by the Fund, the Fund's systems of internal accounting and financial controls and the annual independent audit process.

Each Audit Committee's role is one of oversight, and it is recognized that each Fund's management is responsible for preparing each Fund's financial statements and that each Fund's independent registered public accountant is responsible for auditing those financial statements. Although each Audit Committee member must be financially literate and one member must have accounting or financial management expertise (as determined by the Board in its business judgment), Audit Committee members are not professionally engaged in the practice of accounting or auditing and are not experts in the fields of accounting or auditing, including with respect to auditor independence. Audit Committee members rely, without independent verification, on the information provided to them and on the representations made by management and each Fund's independent registered public accountants.

The members of each Fund's Audit Committee are Mr. Pohotsky, Mr. Reardon, Dr. Reinhardt and Ms. Stebbins. Ms. Stebbins is the Chairman of each Fund's Audit Committee. The Audit Committee of each of HQH and HQL held four meetings during the fiscal year ended September 30, 2014. The Audit Committee of THQ held two meetings during the fiscal year ended September 30, 2014.

Governance and Nominating Committee. Each Fund has a Governance and Nominating Committee comprised solely of Independent Trustees who are "independent" as defined in the NYSE Listing Standards. The Committee charter is not available on the Fund's website but the written charter is included as Exhibit A to this Proxy Statement dated April 27, 2015.

The principal missions of the Governance and Nominating Committee of each Fund are to (i) review, evaluate, and enhance the effectiveness of the Board in its role in governing the Fund and overseeing the management of the Fund and (ii) to promote the effective participation of qualified individuals on the Board, on committees of the Board, and as executive officers of the Fund. The Committee shall consider the Corporate Governance Guidelines that have been approved by the Board in fulfilling its missions.

The Committee of each Fund reviews, discusses and makes recommendations to the Board relating to those issues that pertain to the effectiveness of the Board in carrying out its responsibilities in governing the Fund and overseeing the Fund's management. The Committee makes nominations for trustees and officers of the Fund and for membership on all committees of the Board and submits such nominations to the full Board for consideration.

Each Fund's By-Laws require that each prospective trustee candidate have a college degree or equivalent business experience and provide a list of minimum qualifications for trustees, which include expertise, experience or relationships relevant to the business of the Fund. Each Fund's By-Laws also require that a candidate not be serving in any of various positions with another investment company (as defined in the 1940 Act) that focuses its investments in the healthcare and/or life sciences industries, unless such investment company is managed by the Fund's investment adviser or an affiliate, or in various positions with the investment adviser, sponsor or equivalent of such an investment company. Each Committee may also take into account other factors when considering and evaluating potential trustee candidates, including but not limited to: (i) availability and commitment to attend meetings and perform responsibilities of the Board; (ii) relevant industry and related experience; (iii) educational background; (iv) financial expertise; (v) the candidate's ability, judgment and expertise; and (vi) the overall diversity of the Board's composition.

The Committee of each Fund may identify prospective trustees from any reasonable source, including, but not limited to, the consultation of third-party trustee search services. The Committee will consider potential trustee candidates recommended by shareholders, provided that the proposed candidates (i) satisfy any minimum qualifications of the Fund for its trustees; (ii) are not "interested persons" (as that term is defined in Section 2(a)(19) of the 1940 Act) of the Fund or the Adviser; and (iii) are "independent" as defined in the NYSE Listing Standards. In order to be evaluated by the Committee, trustee candidates recommended by shareholders must also meet certain eligibility requirements as set out in the Committees' charter. Other than those eligibility requirements, the Committee shall not evaluate shareholder trustee nominees in a different manner than other nominees. The standard of the Committee is to treat all equally qualified nominees in the same manner.

All recommendations by shareholders must be received by a Fund by the deadline for submission of any shareholder proposals which would be included in the Fund's proxy statement for the next annual meeting of the Fund. Each shareholder or shareholder group must meet the requirements stated in the Committee's charter in order to recommend a candidate. A shareholder or shareholder group may not submit more than one candidate per year. When recommending a trustee candidate, shareholders must include in their notice to the Fund's Secretary: (i) the shareholder's contact information; (ii) the trustee candidate's contact information and the number of Fund shares owned by the proposed candidate; (iii) all information regarding the candidate that would be required to be disclosed in solicitations of proxies for elections of trustees required by Regulation 14A of the Securities Act of 1934, as amended

(the "Exchange Act"); and (iv) a notarized letter executed by the trustee candidate, stating his or her intention to be a nominee and be named in the Fund's proxy statement, if nominated by the Board, and to serve as a trustee, if so elected. Once a recommendation has been timely received in proper form, the candidate will be asked to complete an eligibility questionnaire to assist the Fund in assessing the candidate's qualifications as a potential Independent Trustee and as someone who is "independent" under the NYSE Listing Standards. The Committee will make such determinations in its sole discretion and such determinations shall be final.

The members of each Fund's Committee are Mr. Bonney, Dr. Jain and Ms. Stebbins. Mr. Bonney is the Chairman of the Committee. During the fiscal year ended September 30, 2014, each Fund's Governance and Nominating Committee met two times.

Valuation Committee. Each Fund's Board has delegated to the Fund's Valuation Committee general responsibility for determining, in accordance with the Fund's valuation procedures, the value of assets held by the Fund on any day on which the net asset value per share is determined. The Valuation Committee may appoint, and has appointed, a Sub-Committee made up of employees and officers of the Adviser to deal with day to day valuation decisions, subject to oversight by the Valuation Committee. The Valuation Committee shall meet as often as necessary to ensure that each action taken by the Sub-Committee is reviewed within a calendar quarter of the occurrence. In connection with its review, the Valuation Committee shall ratify or revise the pricing methodologies authorized by the Sub-Committee since the last meeting of the Valuation Committee. The Valuation Committee is charged with the responsibility of determining the fair value of the Fund's securities or other assets in situations set forth in the Fund's valuation procedures.

The members of each Fund's Valuation Committee are Mr. Bonney, Dr. Omstead, Mr. Pohotsky and Mr. Reardon. Mr. Pohotsky is the Chairman of each Fund's Valuation Committee. During the fiscal year ended September 30, 2014, HQH's and HQL's Valuation Committees each met five times and THQ's Valuation Committee met two times.

Qualified Legal Compliance Committee. Each Fund has a Qualified Legal Compliance Committee ("QLCC") comprised solely of Independent Trustees. The Board of each Fund has adopted a written charter for the QLCC. The principal purpose of the Fund's QLCC is to review and respond to reports of Evidence of a Material Violation (as defined in the QLCC charter). Reporting Evidence of a Material Violation is required under the Standards of Professional Conduct for Attorneys adopted by the U.S. Securities and Exchange Commission (the "SEC") under the Sarbanes-Oxley Act of 2002 (the "Standards"). Under the Standards, if an attorney appearing and practicing before the SEC in the representation of an issuer, such as the Fund, becomes aware of Evidence of a Material Violation by the issuer or by any officer, trustee, employee or agent of the issuer, the Standards provide for the attorney to report such evidence to the issuer's QLCC forthwith. In discharging its role, the QLCC is granted the power to investigate any Evidence of a Material Violation brought to its attention with full access to all books, records, facilities and personnel of the Fund and the power to retain outside counsel, auditors or other experts for this purpose.

The members of each Fund's QLCC are Dr. Jain, Mr. Pohotsky and Mr. Reardon. Mr. Reardon is the Chairman of each Fund's QLCC. Each Fund's QLCC had no cause to meet during the fiscal year ended September 30, 2014.

Attendance.

Each of the Trustees attended at least 80% of the aggregate number of meetings of the Board and the Committees of the Board of each Fund on which such Trustee served during the fiscal year-ended September 30, 2014.

REPORT OF THE AUDIT COMMITTEE OF EACH FUND

Each Fund's Audit Committee reviewed and discussed the Fund's audited financial statements with management for the Fund's fiscal year ended September 30, 2014, and discussed with the Fund's independent registered public accountants, Deloitte & Touche LLP, the matters required to be discussed by the Public Company Accounting Oversight Board ("PCAOB") Standard No. 16, as modified or supplemented. Each Fund's Audit Committee received written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the PCAOB Ethics and Independence Rule 3526 regarding Deloitte & Touche's communications with the Audit Committee concerning independence and discussed with Deloitte & Touche LLP its independence. Based on its review and discussions with management and Deloitte & Touche LLP, the Fund's Audit Committee recommended to the Board that the Fund's audited financial statements for the Fund's fiscal year ended September 30, 2014, be included in the Fund's Annual Report filed with the SEC.

Proposal 2
RATIFICATION OR REJECTION OF SELECTION OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTANTS

Each Fund's Audit Committee has approved the appointment of Deloitte & Touche LLP as the independent registered public accountants for the fiscal year ending September 30, 2015, and a majority of the Board of each Fund, including a majority of the Independent Trustees, subsequently ratified the appointment.

Accounting services to be performed by Deloitte & Touche LLP for each Fund will consist of the examination of the annual financial statements of the Fund, consultation on financial, accounting and reporting matters, review and consultation regarding various filings with the SEC and attendance at some meetings of the Board. Deloitte & Touche LLP also will perform non-audit services consisting of review of income tax returns of each Fund.

A representative of Deloitte & Touche LLP is expected to participate in the Joint Annual Meeting and to be available for questioning and have an opportunity to make a statement.

The following tables set forth the aggregate fees billed for professional services rendered by Deloitte & Touche LLP to each Fund during each Fund's two most recent fiscal years:

All of the services described in the table above were approved by each Audit Committee pursuant to its pre-approval policies and procedures (the "Pre-Approval Policies and Procedures") which are summarized below to the extent that such services were required to be pre-approved by each Audit Committee.

The aggregate non-audit fees billed by Deloitte & Touche LLP for services rendered to each Fund and to the Adviser, or an affiliate thereof that provides ongoing services to the Fund, amounted to $4,650 for the fiscal year ended September 30, 2014 and $4,650 for HQH and HQL for the fiscal year ended September 30, 2013.

Each Fund's Audit Committee has adopted Pre-Approval Policies and Procedures pursuant to which the Committee pre-approves all audit and non-audit services provided by the Fund's independent auditor (the "Auditor") and any non-audit services provided by the Auditor to the Fund's investment adviser and service affiliates ("Service Affiliates") during the period of the Auditor's engagement to provide audit services to the Fund, if those services directly impact the Fund's operations and financial reporting. Audit services include those typically associated with the annual audit such as evaluation of internal controls. Non-Audit services include certain services that are audit-related, such as consultations regarding financial accounting and reporting standards and tax services. Certain services may not be provided by the Auditor to the Fund's or the Fund's Service Affiliates without jeopardizing the Auditor's independence. These services are deemed prohibited services and include certain management functions; human resources services; broker-dealer, investment adviser or investment banking services; legal services; and expert services unrelated to the audit. Other services are conditionally

prohibited and may be provided, if the Audit Committee reasonably concludes that the results of the services will not be subject to audit procedures during an audit of the Fund's financial statements. These types of services include bookkeeping; financial information systems design and implementation; appraisal or valuation services; actuarial services; and internal audit outsourcing services.

The Pre-Approval Policies and Procedures of each Fund's Audit Committee require Audit Committee approval of the engagement of the Auditor for each fiscal year and approval of the engagement by at least a majority of the Fund's Independent Trustees. In determining whether to engage the Auditor for its audit services, each Fund's Audit Committee will consider the Auditor's proposed fees for the engagement, in light of the scope and nature of the audit services that the Fund will receive. The Pre-Approval Policies and Procedures also permit each Fund's Audit Committee to pre-approve the provisions of types or categories of permissible non-audit services for the Fund and its Service Affiliates on an annual basis at the time of the Auditor's engagement and on a project-by-project basis. At the time of the annual engagement of each Fund's Auditor, each Audit Committee is to receive a list of the categories of expected non-audit services with a description and an estimated budget of fees. In their pre-approval, each Audit Committee should determine that the provision of the service is consistent with, and will not impair, the ongoing independence of the Auditor and set any limits on fees or other conditions they find appropriate. Non-audit services may also be approved on a project-by-project basis by each Audit Committee consistent with the same standards for determination and information.

Each Audit Committee may also appoint a member of each Committee to pre-approve non-audit services that have not been pre-approved or material changes in the nature or cost of any non-audit services previously pre-approved. The member may not pre-approve any project the estimated budget (or budgeted range) of fees of which exceed or may exceed $15,000. Any actions by the member are to be ratified by the Audit Committee by the time of its next scheduled meeting. Each Fund's Pre-Approval Policies and Procedures are reviewed annually by the Fund's Audit Committee, and the Fund maintains a record of the decisions made by the Committee pursuant to these procedures.

Required Vote

The selection of Deloitte & Touche LLP as each Fund's independent public accountants for the fiscal year ending September 30, 2015 is submitted to shareholders for ratification and requires approval by a majority of each Fund's shares voting at the Joint Annual Meeting. The Trustees recommend a vote FOR the selection of Deloitte & Touche LLP as the independent registered public accountants of each Fund.

INFORMATION PERTAINING TO THE CUSTODIAN AND ADMINISTRATOR AND
TRANSFER AGENT, DIVIDEND DISBURSING AGENT AND REGISTRAR

Each Fund's securities and cash are held under a custodian contract by State Street Bank and Trust Company ("State Street"), whose principal business address is One Lincoln Street, Boston, MA 02111. State Street is also the Administrator of each Fund and also performs certain accounting related functions for each Fund, including calculation of net asset value and net income.

Computershare Inc. serves as Dividend Disbursing Agent. Computershare Trust Company, N.A., a fully owned subsidiary of Computershare Inc., serves as (1) the Plan Agent for each Fund's Dividend Reinvestment Plan and (2) the Transfer Agent and Registrar for Shares of each Fund. Computershare Trust Company, N.A. and Computershare Inc. have their principal business at 250 Royall Street, Canton, MA 02021.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act and Section 30(j) of the 1940 Act, as applied to each Fund, require the Fund's officers and trustees, investment manager, affiliates of the investment manager, and persons who beneficially own more than ten percent of a registered class of the Fund's outstanding securities ("Reporting Persons") to file reports of ownership of the Fund's securities and changes in such ownership with the SEC and the NYSE. Such persons are required by SEC regulations to furnish the Fund with copies of all such filings.

Based solely upon its review of the copies of such forms received by it, and written representations from certain Reporting Persons that no year-end reports were required for those persons, each Fund believes that during the fiscal year ended September 30, 2014, its Reporting Persons complied with all applicable filing requirements.

OTHER BUSINESS

As of the date of this Joint Proxy Statement, the Board of each Fund is not aware that any matters are to be presented for action at the Joint Annual Meeting other than those described above. Should other business properly be brought before the Annual Meeting, it is intended that the accompanying Proxy will be voted thereon in accordance with the judgment of the persons named as proxies.

PROXIES AND VOTING AT THE ANNUAL MEETING

Shareholders who execute proxies may revoke them at any time before they are voted by written notice to the Secretary of the Fund at 100 Federal Street, 19th Floor, Boston, MA 02110, or by casting a vote at the Joint Annual Meeting. Instructions on how to attend the meeting and vote in person can be obtained by calling (617) 772-8500. All valid proxies received prior to the Joint Annual Meeting, or any adjournment(s) or postponements(s) thereof, will be voted at the Joint Annual Meeting and any adjournments or postponements thereof.

The representation in person or by proxy of a majority of the outstanding shares of each Fund is necessary to constitute a quorum for transacting business at the Joint Annual Meeting. For purposes of determining the presence of a quorum, abstentions and broker "non-votes" will be treated as shares that are present. Broker non-votes are proxies received by each Fund from brokers or nominees when the broker or nominee has neither received instructions from the beneficial owner or other persons entitled to vote nor has discretionary power to vote on a particular matter. Proposals 1 and 2 to be voted upon by the shareholders involve matters that the NYSE considers to be routine and within the discretion of brokers to vote if no customer instructions are received.

Proposal 1 requires the approval of a plurality of shares voting at the Joint Annual Meeting (i.e., the nominees for election receiving the greatest number of votes will be elected).

Proposal 2 requires the approval of a majority of all votes validly cast at the Joint Annual Meeting.

Abstentions and broker non-votes will not be counted in favor of, but will have no other effect on, the votes for Proposal 1 and 2.

Matters on which a choice has been provided will be voted as indicated on the proxy card and, if no instruction is given, the persons named as proxies will vote the shares represented thereby FOR all nominees for election as Trustee and FOR Proposal 2, and will use their best judgment in connection

with the transaction of such other business as may properly come before the Joint Annual Meeting or any adjournment(s) or postponement(s) thereof.

In the event that sufficient votes in accordance with the Trustees' recommendations on any Proposal are not received by June 4, 2015 or the necessary quorum has not been obtained, or if other matters arise requiring shareholder attention, the persons named as proxies on the enclosed proxy card may propose one or more adjournments of the Joint Annual Meeting to permit further solicitation. Any such adjournment will require approval by a majority of the votes validly cast on the matter at the session of the Joint Annual Meeting to be adjourned. When voting on a proposed adjournment, the persons named as proxies will vote FOR the proposed adjournment all shares that they are entitled to vote with respect to each item, unless directed to vote AGAINST an item, in which case such shares will be voted AGAINST the proposed adjournment with respect to that item. A shareholder vote may be taken on one or more items prior to such adjournment, if sufficient votes have been received and it is otherwise appropriate. Abstentions and broker non-votes will be disregarded for purposes of voting on adjournment.

As of April 24, 2015, there were 36,489,523 shares of beneficial interest of HQH issued and outstanding, 19,321,063 shares of beneficial interest of HQL issued and outstanding and 43,878,221 shares of beneficial interest of THQ issued and outstanding. Shareholders of each Fund will be entitled to one vote for each share held. Only shareholders of record at the close of business on April 24, 2015, the record date, will be entitled to vote at the Joint Annual Meeting. As of March 31, 2015, the Trustees and officers of each Fund individually and as a group beneficially owned less than 1% of the outstanding voting securities of the Fund. To the best of each Fund's knowledge, based upon filings made with the SEC, as of April 14, 2015, the below persons or groups beneficially owned more than 5% of the voting securities of the Fund:

  *  Morgan Stanley and/or certain of its operating units (including Morgan Stanley Smith Barney LLC) have shared dispositive power with respect to 3,199,966 shares, sole voting power with respect to 3,064,537 of such shares, and shared voting power with respect to 1,063,934 of such shares.

  **  First Trust Portfolios L.P., First Trust Advisors L.P., and The Charger Corporation have shared dispositive power with respect to 1,361,150, 1,425,000, and 1,425,000 shares, respectively, and shared voting power with respect to 0, 63,850, and 63,850 of such shares, respectively.

PROPOSALS FOR 2016 ANNUAL MEETING

Shareholder proposals for each Fund's 2016 Joint Annual Meeting must be received at the Fund's executive offices at 100 Federal Street, 19th Floor, Boston, Massachusetts 02110 no later than January 1, 2016 for inclusion in the Fund's 2016 proxy statement and form of proxy, unless the meeting date is more than 30 days before or after June 4, 2016, in which case the proposal must be submitted a reasonable time before the time the Fund begins to print and send its proxy materials for the 2016 annual meeting. Submission of such proposals does not insure that they will be included in the Fund's 2016 proxy statement or submitted for a vote at the Fund's 2016 annual meeting.

In addition, shareholder proposals for each Fund's 2016 annual meeting of shareholders (other than proposals submitted for inclusion in the Fund's 2016 proxy statement) must be submitted to the Fund's Secretary between February 9, 2016 and March 11, 2016, unless the meeting date is more than 30 days before or after June 4, 2016, in which case the proposal must be submitted by the later of the close of business on (1) the date 90 days prior to the 2016 annual meeting date or (2) the tenth business day following the date on which the 2016 annual meeting date is first publicly announced or disclosed.

GENERAL

Each Fund will pay the cost of preparing, printing and mailing the enclosed proxy card(s) and Joint Proxy Statement and all other costs incurred in connection with the solicitation of proxies, including any additional solicitation made by letter, Internet, telephone or telegraph. The solicitation of proxies will be largely by mail. In addition, certain officers of the Fund and certain employees of the Adviser, who will receive no compensation for their services other than their regular salaries, may solicit the return of proxies personally or by telephone or facsimile. Banks, brokerage houses, nominees and other fiduciaries will be requested to forward the proxy soliciting materials to the beneficial owners of the shares of each Fund. Each Fund may reimburse brokerage houses, nominees and other fiduciaries for postage and reasonable expenses incurred by them in forwarding of proxy material to beneficial owners.

A number of banks, brokers and financial institutions have instituted "householding". Under this practice, only one Joint Proxy Statement may be delivered to multiple shareholders who share the same address and satisfy other conditions. Each Fund will deliver promptly a separate copy of this Joint Proxy Statement to a shareholder at a shared address upon request. To request a separate copy of this Joint Proxy Statement, write or call the Fund at the address and phone number set forth above.

EXHIBIT A

Governance and Nominating Committee Charter

For convenience, this Charter refers to the Funds and their respective Boards of Trustees (each the "Board"), and their respective Governance and Nominating Committees (each the "Committee" or the "Governance and Nominating Committee") in the singular. However, this Charter applies to each Fund, its Board and its Committee independently.

Committee Membership

The Committee shall consist entirely of trustees of the Fund who (1) are not "interested persons," as that term is defined in the Investment Company Act of 1940, as amended (the "1940 Act"), of the Fund or the Fund's investment adviser and (2) are "independent" as defined in the New York Stock Exchange ("NYSE") Listing Standards ("Independent Trustees"). The President of the Fund, although not a member of the Committee, will cooperate with the Committee by assisting the Committee to discharge its responsibilities, including by recommending candidates and recruiting them for the Board or to serve as executive officers of the Fund.

Missions

The principal missions of the Committee are (i) to review, evaluate, and enhance the effectiveness of the Board in its role in governing the Fund and overseeing the management of the Fund and (ii) to promote the effective participation of qualified individuals on the Board, on committees of the Board, and as executive officers of the Fund. The Committee shall consider the Corporate Governance Guidelines attached to this Charter as Appendix A in fulfilling its missions.

Governance Function

The Committee shall review, discuss, and make recommendations to the Board relating to those issues that pertain to the effectiveness of the Board in carrying out its responsibilities in governing the Fund and overseeing the management of the Fund. These may include, but are not limited to, issues relating to:

1.  the selection of the Fund's investment adviser (the "Adviser") and approval of the Fund's investment advisory contract;

2.  the selection and approval of the Fund's outside counsel ("Fund Counsel");

3.  the composition of the Board, including:

(a)  the size of the Board and the qualifications and representative areas of expertise of the members of the Board; and

(b)  retirement and succession policies relating to members of the Board;

4.  the members of the Board, including:

(a)  guidelines relating to ownership of shares of the Fund by members of the Board;

(b)  whether members of the Board may not serve in a similar capacity on the board of a registered investment company (i) which is not sponsored or advised by the Adviser or its affiliates and (ii) which the Committee in its discretion has determined to be competitive with the Fund taking into account such registered investment company's investment mandate;

(c)  continuing education of members of the Board; and

(d)  identification of best practices for members of the Board;

5.  the meetings of the Board, including:

(a)  coordination with the Chairman of the Board in developing the agenda for the meetings of the Board, with the assistance of the Adviser and Fund Counsel;

(b)  frequency of meetings of the Board; and

(c)  Board meeting attendance policies;

6.  the role of the Independent Trustees, including:

(a)  limitations on the ability of Independent Trustees to act and function independently of the Board and the Adviser; and

(b)  the quality of information received by the Independent Trustees;

7.  compensation for Independent Trustees;

8.  the role of the committees of the Board, including:

(a)  number and type of committees; and

(b)  periodic approval of the charter and scope of the responsibilities of each committee;

9.  the relationship between the Board and management, including:

(a)  oversight of and communication with management;

(b)  coordination with management to ensure that management has developed an appropriate plan to deal with succession and potential crisis management situations; and

10.  Board self-evaluation.

Nominating Function – Board

1.  The Committee shall make nominations for trustees and officers of the Fund and submit such nominations to the full Board. The Committee shall evaluate candidates' qualifications for such positions and, in the case of candidates for election to the Board, whether they would qualify as Independent Trustees. The Committee shall also consider the effect of any relationships beyond those delineated in the 1940 Act that might impair independence (e.g. business, financial or family relationships with the Adviser). In determining candidates' qualifications for Board membership, the Committee shall consider factors which may be delineated in this Charter or the Fund's By-Laws and may consider such other factors as it may determine to be relevant to fulfilling the role of being a member of the Board.

2.  The Committee may consider potential trustee candidates recommended by shareholders, provided that the proposed candidates: (i) satisfy any minimum qualifications of the Fund for its trustees; and (ii) qualify as Independent Trustees. In order for the Committee to evaluate any nominee recommended by a shareholder or shareholder group, potential trustee candidates and nominating shareholders or shareholder groups must satisfy the requirements provided in Appendix B to this Charter. The Committee shall not otherwise evaluate shareholder trustee nominees in a different manner than other nominees, and the standard of the Committee is to treat all equally qualified

nominees in the same manner. Once a nomination has been timely received in proper form, the nominee will be asked to complete an eligibility questionnaire to assist the Committee in assessing the nominee's qualifications as a potential Independent Trustee. The Committee will make such determinations in its sole discretion and such determinations shall be final.

3.  The Committee may identify prospective trustees from any reasonable source, including, but not limited to, the consultation of third-party trustee search services.

4.  The Committee requires that each prospective trustee have a college degree or equivalent business experience. In addition to the requirements delineated in the Fund's By-Laws, the Committee may take into account a wide variety of factors in considering prospective trustees, including (but not limited to): (i) availability and commitment of a candidate to attend meetings and perform his or her responsibilities on the Board; (ii) relevant industry and related experience; (iii) educational background; (iv) financial expertise; (v) the candidate's ability, judgment and expertise; and (vi) overall diversity of the Board's composition.

6.  The Committee shall evaluate the participation and contribution of each trustee coming to the end of his or her term before deciding whether to recommend reelection. The Committee may seek the views of other trustees to assist them in this evaluation.

Nominating Function – Committees

The Committee shall make nominations for membership on all committees of the Board and submit such nominations to the full Board and shall review committee assignments as necessary.

Other Powers and Responsibilities

1.  The Committee shall meet at least annually so it can carry out its review of the investment advisory agreement, recommend the selection of an Adviser, and consider Board and Committee nominations. The Committee shall meet at such other time or times as the Committee or the Board may determine appropriate or necessary and is empowered to hold special meetings as circumstances require.

2.  The Committee shall have the resources and authority appropriate to discharge its responsibilities, including authority to utilize Fund Counsel and to retain experts or other persons with specific competence at the expense of the Fund.

3.  The Committee shall review this Charter periodically and recommend any changes to the Board.

In the case of a candidate to serve as an Independent Trustee, independence will be required in terms of both the letter and spirit of applicable law.

In the event of any conflict of interests, a trustee shall promptly disclose such conflict to the Chairman of the Board and Fund Counsel and recuse him or herself from any discussions or votes involving the conflict.

(f)  The proceedings of the Board and its committees are confidential. Each trustee shall maintain the confidentiality of information received as part of his or her duty as a trustee.
