                            COMBINED PROXY STATEMENT

                      JOINT ANNUAL MEETING OF SHAREHOLDERS
                    TO BE HELD ON THURSDAY, AUGUST 14, 2003

   Meeting Information.  The Board of Directors or Trustees (each Board is
hereafter referred to as a "Board of Directors" and Board members are referred
to as "Directors") of each Fund listed on the accompanying Notice is soliciting
your proxy to be voted at the Joint Annual Meeting of Shareholders to be held on
Thursday, August 14, 2003 at 11:00 a.m. at Two Commerce Square, 2001 Market
Street, 2nd Floor, Philadelphia, Pennsylvania and/or at any adjournments of the
meeting (hereafter, the "Meeting").

   Purpose of Meeting.  The purpose of the Meeting is to consider the Proposal
listed in the accompanying Notice. The Board of Directors of each Fund urges you
to complete, sign and return the Proxy Card (or Cards) included with this
Combined Proxy Statement, whether or not you intend to be present at the
Meeting. It is important that you provide voting instructions promptly to help
assure a quorum for the Meeting.

   General Voting Information.  You may provide proxy instructions by returning
the Proxy Card(s) by mail in the enclosed envelope. The persons designated on
the Proxy Card(s) as proxies will vote your shares as you instruct on each Proxy
Card. If you return a signed Proxy Card without any voting instructions, your
shares will be voted "FOR" each of the nominees for election as Director. The
persons designated on the Proxy Card as proxies will also be authorized to vote
(or to withhold their vote) in their discretion on any other matters which
properly come before the Meeting. They may also vote in their discretion to
adjourn the Meeting. If you sign and return a Proxy Card, you may still attend
the Meeting to vote your shares in person. If your shares are held of record by
a broker and you wish to vote in person at the Meeting, you should obtain a
Legal Proxy from your broker of record and present it at the Meeting. You may
also revoke your proxy at any time before the Meeting: (i) by notifying Delaware
Investments in writing at 2005 Market Street, Philadelphia, PA 19103; (ii) by
submitting a later signed Proxy Card; or (iii) by voting your shares in person
at the Meeting. If your shares are held in the name of your broker, you will
have to make arrangements with your broker to revoke any previously executed
proxy.

   Each shareholder may cast one vote for each full share and a partial vote for
each partial share of a Fund that they owned of record on June 17, 2003. Exhibit
A shows the number of shares of each Fund that were outstanding on the record
date and Exhibit B lists the shareholders who owned 5% or more of each Fund on
that date. It is expected that this Combined Proxy Statement and the
accompanying Proxy Card(s) will be mailed to shareholders of record on or about
July 2, 2003.

   This proxy solicitation is being made largely by mail, but may also be made
by officers or employees of the Funds or their investment manager or affiliates,
through telephone, facsimile, or other communications. The Funds may also employ
a professional proxy solicitation firm, although they do not presently intend to
do so. The cost of the solicitation is being borne by the Funds. The Funds may
reimburse banks, brokers or dealers for their reasonable expenses in forwarding
soliciting materials to beneficial owners of the Funds' shares.




   Required Votes. All shareholders of a Fund vote together to elect Directors,
regardless of whether the Fund has both common and preferred shareholders, with
one exception. The holders of preferred shares of each of the Funds that have
issued one or more classes of preferred shares ("Preferred Share Funds") have
the exclusive right to separately elect two Directors, in addition to the right
to vote for the remaining Directors together with the holders of the common
shares. Each of the Funds except Delaware Investments Dividend and Income Fund,
Inc. ("DDF") and Delaware Investments Global Dividend and Income Fund, Inc.
("DGF") have issued preferred shares.

   The amount of votes of each Fund that are needed to approve proposals varies.
The voting requirements with respect to the election of Directors are described
within Proposal One. Abstentions will be included for purposes of determining
whether a quorum is present for each Fund at the Meeting. They will be treated
as votes present at the Meeting, but will not be treated as votes cast. They
therefore would have no effect on a proposal which requires a plurality or
majority of votes cast for approval, but would have the same effect as a vote
"AGAINST" a proposal requiring a majority of votes present. Because the Proposal
presented is considered to be a "routine" voting item, the Funds do not expect
to recognize broker non-votes.

   In the event that a quorum is not present or if sufficient votes are not
received consistent with management's recommendation on the adoption of the
Proposal, management may propose an adjournment or adjournments of the Meeting
for a Fund. Any adjournment would require a vote in favor of the adjournment by
the holders of a majority of the shares present at the Meeting in person or by
proxy. The persons named as proxies may vote (or withhold their vote) in their
discretion on any proposed adjournment.

PROPOSAL ONE: TO ELECT A BOARD OF DIRECTORS FOR EACH FUND

   You are being asked to elect each of the current members of the Board of
Directors for your Fund. The nominees are: Jude T. Driscoll, David K. Downes,
Walter P. Babich, John H. Durham, John A. Fry, Anthony D. Knerr, Ann R. Leven,
Thomas F. Madison and Janet L. Yeomans.

If elected, these persons will serve as Directors until the next annual meeting
of shareholders called for the purpose of electing Directors, and/or until their
successors have been elected and qualify for office. It is not expected that any
nominee will withdraw or become unavailable for election, but in such a case,
the power given by you in the Proxy Card may be used by the persons named as
proxies to vote for a substitute nominee or nominees as recommended by the
existing Board of Directors.

   The Preferred Share Funds each issue shares of common stock and shares of
preferred stock. The governing documents of each Preferred Share Fund provide
that the holders of preferred shares of the Fund are entitled to elect two of
the Fund's Directors, and the remaining Directors are to be elected by the
holders of the preferred shares and common shares voting together. The nominees
for Directors to be voted on separately by the preferred shareholders of such
Funds are Thomas F. Madison and Janet L. Yeomans.

   Each Fund has an Audit Committee for the purpose of meeting, at least
annually, with the Fund's officers and independent auditors to oversee the
quality of financial reporting and the internal controls of each Fund, and for
such other purposes as the Board of Directors may from time to time direct. The
Audit Committee of each Fund consists of the following three Directors appointed
by the Board: Ann R. Leven, Chairperson; Thomas F. Madison; and Janet L.
Yeomans. Members of the Audit Committee serve for three years or until their
successors have been appointed and qualified. The Audit Committee held five
meetings for DDF and DGF for the fiscal year ended November 30, 2002 and four
meetings for the Preferred Share Funds for the fiscal year ended March 31, 2003.
The Board of Directors of each Fund has adopted a written charter for each
Fund's Audit Committee, attached as Exhibit C.

   Each Board of Directors also has a Nominating Committee, which meets for the
purpose of proposing nominees to serve as Directors. Nominees are considered by
the full Board of Directors for each Fund and, when appropriate, by shareholders
at annual or special shareholder meetings. The Nominating Committee of each Fund
currently consists of the following three Directors appointed by the Board:
Anthony D. Knerr, Chairperson; John H. Durham; and John A. Fry, all of whom are
independent. The selection and nomination of the independent Director nominees
is committed to the discretion of the present independent Directors. The
Nominating Committee will consider suggestions for Board of Directors
nominations from shareholders. Shareholders who wish to suggest candidates for
nomination to the Boards of Directors at any future annual meeting should
identify the candidate and furnish a written statement of the person's
qualifications to the Nominating Committee at the principal executive offices of
the Funds. Nominations should be received by the date set forth under
"Shareholder Proposals" on page 9. The Nominating Committee for each Fund held
two meetings during the fiscal year ended November 30, 2003 for DDF and DGF and
March 31, 2003 for the Preferred Share Funds.

   Board Compensation. Each independent Director receives compensation from each
Fund of which he/she is a member of the Board of Directors. The interested
Directors are compensated by the investment adviser and do not receive
compensation from the Funds. Each independent Director currently receives a
total annual retainer fee of $55,000 for serving as a Director of all 32
investment companies within the Fund Complex, plus $3,145 per day for each day
the Board meets (normally four regular meetings, all of which are two day
meetings). Walter P. Babich is the current Coordinating Director for the Funds
and receives an additional retainer totaling $10,000 with respect to all 32
investment companies within the Fund Complex. Members of the Audit Committee
currently receive additional annual compensation totaling $5,000 from all of the
investment companies within the Fund Complex, plus $1,000 for each meeting in
excess of five in any calendar year. The chairperson of the Audit Committee
receives an annual retainer of $8,000, plus $1,000 for each meeting in excess of
five in any calendar year. Independent Directors who are members of the
Nominating Committee receive $1,000 for each committee meeting. In addition, the
chairperson of the Nominating Committee receives an annual retainer of $500.

   Under the terms of each Fund's retirement plan for Directors, each
independent Director who, at the time of his or her retirement from the Board of
Directors, has attained the age of 70 and has served on the Board of Directors
for at least five continuous years, is entitled to receive payments from the
Fund Complex for a period of time equal to the lesser of the number of years
that the person served as a Director or the remainder of the person's life. The
annual amount of such payments will be equal to the amount of the annual
retainer that is paid to Directors of the investment companies at the time of
the person's retirement. If an eligible Director of each investment company
within the Fund Complex had retired as of May 31, 2003, he or she would have
been entitled to annual payments in the amount of $55,000. The following table
identifies the amount each Director received from each Fund during its last
fiscal year and from the Fund Complex as a whole during the twelve months ended
May 31, 2003.

   Officers. Each Board of Directors and the senior management of the Funds
appoint officers each year, and from time to time as necessary. The following
individuals are executive officers of one or more of the Funds: Jude T.
Driscoll, David K. Downes, Richelle S. Maestro and Michael P. Bishof. Exhibit D
includes biographical information and the past business experience of such
officers, except for Mr. Driscoll and Mr. Downes, whose information is set forth
herein along with the other Directors. The Exhibit also identifies which of
these executive officers are also officers of Delaware Management Company
("DMC"), the investment adviser of each Fund, or Delaware International Advisers
Ltd. ("DIAL"), the sub-adviser to Delaware Investments Global Dividend and
Income Fund, Inc. The above officers of the Funds own shares of common stock
and/or options to purchase shares of common stock of LNC, the ultimate parent of
DMC and DIAL. They are considered to be "interested persons" of the Funds under
the Investment Company Act of 1940, as amended (the "1940 Act").

   Section 16(a) Beneficial Ownership Reporting Compliance. Section 16 of the
Securities Exchange Act of 1934, as amended, requires that Forms 3, 4, and 5 be
filed with the SEC, the relevant securities exchange and the relevant Fund, by
or on behalf of certain persons, including directors, certain officers, and
certain affiliated persons of the investment adviser or sub-adviser. The Funds
believe that these requirements were met, except that management failed to
timely file a Form 3 on behalf of Richelle S. Maestro.

AUDIT COMMITTEE REPORT

   As required by its charter, each Fund's Audit Committee has reviewed and
discussed with Fund management and representatives from Ernst & Young LLP, the
Funds' independent auditors, the audited financial statements for each Fund's
last fiscal year. The Audit Committee has discussed with the independent
auditors the matters required to be discussed by Statement of Auditing Standards
61. The Audit Committee also received the written disclosures and the letter
from its independent auditors required by Independence Standards Board No. 1,
and discussed with a representative of Ernst & Young LLP the independent
auditor's independence. Each Fund's Board of Directors considered the financial
information systems design and implementation fees and other fees received by
Ernst & Young LLP from DMC and its affiliates during the last fiscal year in
connection with its consideration of the auditors' independence. Based on the
foregoing discussions with management and the independent auditors, each Fund's
Audit Committee unanimously recommended to the Fund's Board of Directors that
the aforementioned audited financial statements be included in each Fund's
annual report to shareholders for the last fiscal year.

   As noted above, the members of each Fund's Audit Committee are: Ann R. Leven,
Thomas F. Madison and Janet L. Yeomans. All members of each Fund's Audit
Committee meet the standard of independence set forth in the listing standards
of the New York and American Stock Exchanges, as applicable, and are not
considered to be "interested persons" under the 1940 Act. The Fund's Board of
Directrors has adopted a formal charter for the Audit Committee setting forth
its responsibilities. A copy of the Audit Committee's charter is included in
Exhibit C to this Combined Proxy Statement.

                            AUDIT COMMITTEE CHARTER

1. Committee Composition.

(a)  The Audit Committee shall be composed of not less than three
     Directors/Trustees selected by the Board, each of whom shall be independent
     as defined in Rule 10A-3(b) under the Securities Exchange Act of 1934 and
     the listing standards of any national securities exchange on which the Fund
     is listed.

(b)  Each member of the Audit Committee shall be financially literate, as such
     qualification is interpreted by the Fund's Board in its business judgment,
     or must become financially literate within a reasonable period of time
     after his or her appointment to the Audit Committee. At least one member of
     the Audit Committee must be an "audit committee financial expert," as such
     term is defined in the rules and regulations under the Investment Company
     Act of 1940.

(c)  One member of the Committee shall be designated by the Board as
     Chairperson. Each member of the Committee shall serve for three years or
     until his or her successor has been appointed and qualified. The
     Chairperson and members of the Committee shall receive such compensation
     for their service on the Committee as the Board may determine from time to
     time.

2. Role of the Committee. The function of the Audit Committee is oversight in
the sense that it is to watch closely, to maintain surveillance, carefully
review relevant matters and make appropriate suggestions; it is management's
responsibility to direct, manage and maintain appropriate systems for accounting
and internal control, and the auditor's responsibility to plan and carry out a
proper audit. The outside auditor for the Fund is ultimately accountable to the
Audit Committee of the Fund. The Audit Committee shall select, evaluate and,
where appropriate, replace the outside auditor.

3. Purposes. The purposes of the Audit Committee are:

(a)  to monitor the Fund's accounting and financial reporting policies and
     practices, its internal controls and, as appropriate, the internal controls
     of certain service providers;

(b)  to monitor the quality and objectivity of the Fund's financial statements
     and the independent audit thereof;

(c)  to act as a liaison between the Fund's independent auditors and the full
     Board of Directors/Trustees;

(d)  to monitor the Fund's safeguards with respect to both inflow and outflow of
     funds and the integrity of computer systems; and

(e)  to discharge its fiduciary responsibility with respect to evidence of any
     material violation of federal or state law or breach of fiduciary duty
     impacting the Fund that is brought to the attention of the Audit Committee
     pursuant to applicable regulations.

                                       14



4. Duties and Powers. To carry out its purposes, the Audit Committee shall have
the following duties and powers:

(a)  to select, retain or terminate the external auditors and, in connection
     therewith, annually to receive, evaluate and discuss with the external
     auditors a formal written report from them setting forth all consulting or
     other non-audit engagements and other relationships with the Fund, the
     Investment Manager or their affiliates, which shall include specific
     representations as to their objectivity and independence;

(b)  to meet with the Fund's external auditors, including private meetings as
     necessary (i) to consider and pre-approve all audit and non-audit services
     to be provided to the Fund, and all non-audit services to be provided to
     the Fund's Investment Manager and any entity controlling, controlled by, or
     under common control with the Investment Manager that provides ongoing
     services to the Fund where the nature of such services has a direct impact
     on the operations or financial reporting of the Fund; (ii) to establish, if
     deemed necessary or appropriate as an alternative to Audit Committee
     pre-approval of services to be provided by the external auditor as required
     by subparagraph (i) above, policies and procedures to permit such services
     to be pre-approved by other means, such as by action of a designated member
     or members of the Audit Committee, subject to subsequent Audit Committee
     review or oversight; (iii) to review the arrangements for and scope of the
     annual audit and any special audits; (iv) to discuss any matters of concern
     relating to the Fund's financial statements, including any adjustments to
     such statements recommended by the auditors, or other results of said
     audit(s); (v) to consider the auditors' comments with respect to the Fund's
     financial policies, procedures and internal accounting controls and
     management's responses thereto; (vi) to review the form of opinion the
     auditors propose to render to the Board and shareholders; and (vii) in
     addition to the other responsibilities set forth in this Charter, in the
     case of an exchange-listed Fund only, to review the Fund's audited
     financial statements with the auditors and management and make a
     recommendation on including such financial statements in the Fund's annual
     report to shareholders;

(c)  to consider the effect upon the Fund of any changes in accounting
     principles or practices proposed by management or the auditors;

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

(e)  to establish procedures for: (i) the receipt, retention and treatment of
     complaints received by the Fund regarding accounting, internal accounting
     controls or auditing matters; and (ii) the confidential, anonymous
     submission by employees of the Fund's service providers of concerns
     regarding questionable accounting or auditing matters;

(f)  to conduct an annual performance evaluation of the Audit Committee; and

(g)  to report its activities to the full Board on a regular basis and to make
     such recommendations with respect to the above and other matters as the
     Committee may deem necessary or appropriate.

                                       15



5. Meetings. The Committee shall meet on a regular basis and is empowered to
hold special meetings as circumstances require. The Committee shall regularly
meet with the Chief Financial Officer and Treasurer of the Fund and with
internal auditors for the Investment Manager.


6. Resources. The Committee shall have the resources and authority appropriate
to discharge its responsibilities, including the authority to retain special
counsel and other experts or consultants at the expense of the Fund.

7. Annual Charter Review. The Committee shall review this Charter at least
annually and recommend any changes to the full Board of Directors/Trustees.
