PROXY STATEMENT

JOINT ANNUAL MEETING OF SHAREHOLDERS
TO BE HELD ON THURSDAY, SEPTEMBER 12, 2002

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, September 12, 2002 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 the 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 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 July 18,
2002. 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 Proxy Statement and the
accompanying Proxy Card(s) will be mailed to shareholders of record on or about
July 30, 2002.

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 vote to elect each of the current members of the
Board of Directors for your Fund. The nominees are: Charles E. Haldeman, Jr.,
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.

Board and Committee Meetings. During the last full fiscal year, each Fund
held four Board meetings, three of which were two day meetings. All of the
Directors attended at least 75% of those meetings.

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 Jan L. Yeomans.
Members of the Audit Committee serve for three years or until their successors
have been appointed and qualified. The Audit Committee for each Fund held five
meetings during the fiscal year ended November 30, 2001 for DDF and DGF and
March 31, 2002 for the Preferred Share Funds. 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 four Directors appointed by the Board:
Anthony D. Knerr, Chairperson; John H. Durham; and John A. Fry, all of whom are
independent; and David K. Downes. 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 did not meet during the fiscal year ended November 30, 2001 for DDF and DGF
and March 31, 2002 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 manager 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 33
investment companies within the Fund Complex, plus $3,145 per day for each day
the Board meets (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 totalling $10,000 with respect to all 33 investment
companies within the Fund Complex. Members of the Audit Committee currently
receive additional annual compensation totalling $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 June 30, 2002, 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
June 30, 2002.

(1) Prior to May 1, 2000, Mr. Durham was not a member of the Board of Directors
of any Preferred Share Fund.
(2) Mr. Fry was appointed to the Board of Directors on January 1, 2001.

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:
Charles E. Haldeman, Jr., David K. Downes, William E. Dodge, Jude T. Driscoll,
Richard J. Flannery, Richelle S. Maestro and Michael P. Bishof. Exhibit D
includes biographical information and the past business experience of such
officers, except for Mr. Haldeman and Mr. Downes, whose information is set forth
above along with the other Directors. The Exhibit also identifies which officers
are also officers of Delaware Management Company ("DMC"), the investment manager
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 Lincoln National Corporation ("LNC"), the ultimate parent of DMC
and DIAL. They are considered to be "interested persons" of the Funds under 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 manager or sub-adviser. The Funds
believe that these requirements were met, except that management failed to
timely file a Form 3 on behalf of Mitchell L. Conery.

Required Vote. Provided that a quorum is present at the Meeting, either in
person or by proxy, the following votes are required to elect each Fund's Board
of Directors. The holders of the preferred shares of the Preferred Share Funds
have the exclusive right to vote to elect Mr. Madison and Ms. Yeomans to the
Board of Directors of those Funds.

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 the 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 the 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
Directors 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 proxy statement.

Audit Fees. The aggregate fees paid to Ernst & Young LLP in connection

AUDIT COMMITTEE CHARTER

1. Committee Composition. The Audit Committee shall be composed of not
less than three qualified and Independent (as defined and described in
Attachment A hereto) Directors/Trustees selected by the Board, one of whom shall
be designated 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. 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; and

(d) to monitor the Fund's safeguards with respect to both inflow and
outflow of funds, Y2K compliance and the integrity of computer
systems.

The outside auditor for the Fund is ultimately accountable to the Board
of Directors/Trustees and Audit Committee of the Fund. The Audit Committee and
Board of Directors/Trustees have the ultimate authority and responsibility to
select, evaluate and, where appropriate, replace the outside auditor (or to
nominate the outside auditor to be proposed for shareholder approval in any
proxy statement).

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.

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

(a) to recommend the selection, retention or termination of 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
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 review the arrangements for and scope
of the annual audit and any special audits; (ii) 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); (iii) to consider the
auditors' comments with respect to the Fund's financial policies,
procedures and internal accounting controls and management's
responses thereto;

and (iv) to review the form of opinion the auditors propose to
render to the Board and 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 the fees charged by the auditors for audit and non-audit
services; and

(e) 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.

4. 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.

5. 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
appropriate Fund(s).

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

ATTACHMENT A
to
AUDIT COMMITTEE CHARTER
of
DELAWARE INVESTMENTS
FAMILY OF FUNDS

1. Independent Defined. To qualify as "Independent" for these purposes,
Directors/Trustees may have no relationship to the Fund, the Investment Manager
or their affiliates that may interfere with the exercise of their independence
from management and the Funds, must be "Independent Directors" within the
meaning of Section 121A of the listing standards of the American Stock Exchange
and may not be "interested persons" as defined in the Investment Company Act of
1940.

2. Membership Qualifications. In addition to the definition of
Independent provided in paragraph 1 above, the following restrictions shall
apply to every Audit Committee member:

(a) Financial Literacy. 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 have accounting or related financial management
expertise, as the Board interprets such qualification in its business
judgment.

(b) Employees. A Director/Trustee who is an employee (including
non-employee executive officers) of the Fund, the Investment Manager or
any of their affiliates may not serve on the Audit Committee until
three years following termination of his or her employment. In the
event the employment relationship is with a former parent or
predecessor of the Fund, the Investment Manager or their affiliates,
the Director/Trustee could serve on the Audit Committee after three
years following the termination of the relationship between the Fund
and the former parent or predecessor of the Fund, the Investment
Manager or their affiliates.

(c) Business Relationship. A Director/Trustee (i) who is a partner,
controlling shareholder, or executive officer of an organization that
has a business relationship with the Fund or (ii) who has a direct
business relationship with the Fund (e.g., a consultant) may serve on
the Audit Committee only if the Fund's Board of Directors/Trustees
determines in its business judgment that the relationship does not
interfere with the Director/Trustee's exercise of independent judgment.
In making a determination regarding the independence of a
Director/Trustee pursuant to this paragraph, the Board of
Directors/Trustees should consider, among other things, the materiality
of the relationship to the Fund, the Investment Manager or their
affiliates, to the director and, if applicable, to the organization
with which the Director/Trustee is affiliated.

"Business relationships" can include commercial, industrial, banking,
consulting, legal, accounting and other relationships. A
Director/Trustee can have this relationship directly with the Fund, or
the Director/Trustee can be a partner, officer or employee of an
organization that has such a relationship. The Director/Trustee may
serve on the Audit Committee without the above-referenced Board of
Directors'/Trustees' determination after three years following the
termination of, as applicable, either (1) the relationship between the
organization with which the Director/Trustee is affiliated and the
Fund, (2) the relationship between the Director/Trustee and his or her
partnership status, shareholder interest or executive officer position,
or (3) the direct business relationship between the Director/Trustee
and the Fund.

(d) Cross Compensation Committee Link. A Director/Trustee who is employed
as an executive of a corporation where any of the Fund's executives
serves on that corporation's compensation committee may not serve on
the Audit Committee.

(e) Immediate Family. A Director/Trustee who is an Immediate Family member
of an individual who is an executive officer of the Fund, the
Investment Manager or any of their affiliates cannot serve on the Audit
Committee until three years following the termination of such
employment relationship.

(f) Independence Requirement of Audit Committee Members. Notwithstanding
the requirements of subparagraphs 2(b) and 2(e) hereof, one
Director/Trustee who is no longer an employee or who is an Immediate
Family member of a former executive officer of the Fund, the Investment
Manager or their affiliates, but is not considered independent pursuant
to these provisions due to the three-year restriction period, may be
appointed, under exceptional and limited circumstances, to the Audit
Committee if the Fund's Board of Directors/Trustees determines in its
business judgment that membership on the Committee by the individual is
required by the best interests of the Fund and its shareholders, and
the Fund discloses, in the next annual proxy statement subsequent to
such determination, the nature of the relationship and the reasons for
that determination.

3. Definitions.

"Immediate Family" includes a person's spouse, parents, children,
siblings, mothers-in-law, sons and daughters-in-law, brothers and
sisters-in-law, and anyone (other than employees) who shares such
person's home.

"Affiliate" includes a subsidiary, sibling company, predecessor, parent
company, or former parent company.

"Officer" shall have the meaning specified in Rule 16a-1(f) under the
Securities Exchange Act of 1934, or any successor rule.

4. Written Affirmation. With respect to any subsequent changes to the
composition of the Audit Committee, and otherwise approximately once each year,
the Fund should provide the New York Stock Exchange Written Affirmation in the
form attached hereto regarding:

(a) Any determination that the Company's Board of Directors/Trustees has
made regarding the independence of Director/Trustees pursuant to any of
the subparagraphs above;

(b) The financial literacy of the Audit Committee members;

(c) The determination that at least one of the Audit Committee members has
accounting or related financial expertise; and

(d) The annual review and reassessment of the adequacy of the Audit
Committee Charter.
