                                PROXY STATEMENT
 
     The accompanying proxy is solicited by the Board of Trustees of the Fund
for use at the second annual meeting of shareholders of the Fund, to be held on
May 9, 2005 at 11:30 a.m., Central time (the "Annual Meeting"), and at any
adjournment thereof. At the Annual Meeting, shareholders will be asked to
consider (1) the election of Peter C. Erichsen and Ronald A. Nyberg to the Board
of Trustees of the Fund and (2) the approval of an amendment to the Fund's
Second Amended and Restated Bylaws (the "Bylaws") relating to the election of
Trustees by the holders of the Fund's outstanding preferred shares. This Proxy
Statement and the form of proxy were first mailed to shareholders on or about
[          ], 2005.
 
     The Board of Trustees has fixed the close of business on March 15, 2005 as
the record date for the determination of shareholders entitled to notice of and
to vote at the Annual Meeting and any adjournment thereof. As of the close of
business on that date, the Fund had issued and outstanding [          ] common
shares of beneficial interest, no par value ("Common Shares"), and 8,200
preferred shares of beneficial interest, no par value ("Preferred Shares" and,
together with the Common Shares, the "Shares"). The Common Shares and Preferred
Shares are the only classes of shares currently authorized by the Fund. As of
the close of business on March 15, 2005, no person owned of record or, to the
knowledge of the Fund, owned beneficially more than five percent (5%) of the
outstanding Shares of either class, except that Cede & Co., as nominee for
participants in The Depository Trust Company, held of record [          ] Common
Shares (representing approximately [          ]% of the outstanding Common
Shares) and all 8,200 outstanding Preferred Shares. Cede & Co.'s address is 55
Water Street, 25th Floor, New York, New York 10041-0001.
 
     Shareholders of the Fund as of the close of business on March 15, 2005 will
be entitled to one vote for each Share held, and a fractional vote with respect
to fractional Shares, with no cumulative voting rights. Holders of the Preferred
Shares ("Preferred Shareholders") and holders of Common Shares ("Common
Shareholders") will vote separately by class at the Annual Meeting on the
election of Peter C. Erichsen. Pursuant to the Investment Company Act of 1940,
as amended (the "1940 Act"), Preferred Shareholders, voting as a single class,
will have the right to elect two Trustees of the Fund. These Trustees are
currently Ronald E. Toupin, Jr. (whose term of office will expire at the 2006
annual meeting) and Ronald A. Nyberg, who will stand for re-election at the
Annual Meeting. The Preferred Shareholders, voting as a
 
                                        1

 
single class, have the right to vote on the election of Mr. Nyberg. Pursuant to
the 1940 Act, the Common Shareholders do not have the right to vote with respect
to the election of Mr. Nyberg. Pursuant to the Bylaws, only the Preferred
Shareholders, voting as a single class, will vote on the proposed amendment to
the Bylaws. Common Shareholders and Preferred Shareholders will vote as a single
class on any other matter properly brought before the Annual Meeting (except as
otherwise required by the Fund's Amended and Restated Agreement and Declaration
of Trust (the "Declaration of Trust") and Bylaws and applicable law). The table
below summarizes the right of the Common Shareholders and Preferred Shareholders
to vote with respect to the matters to come before the Annual Meeting.

- Proposal 1: Election of Peter C. Erichsen                     X                      X
- Proposal 1: Election of Ronald A. Nyberg                                             X
- Proposal 2: Approval of an amendment to the Bylaws                                   X
  relating to the election of Trustees by the
  Preferred Shareholders

 
     Thirty percent (30%) of the Common Shares of the Fund entitled to vote at
the Annual Meeting and thirty percent (30%) of the Preferred Shares of the Fund
entitled to vote at the Annual Meeting must be represented in person or by proxy
to constitute a quorum with respect to the election of Mr. Erichsen. Thirty
percent (30%) of the Preferred Shares of the Fund entitled to vote at the Annual
Meeting must be represented in person or by proxy to constitute a quorum with
respect to the election of Mr. Nyberg and Proposal 2. Each shareholder has the
right to revoke his or her proxy at any time before it is voted. A proxy may be
revoked by filing with the Secretary of the Fund a written revocation or a
properly executed proxy bearing a later date or by voting in person at the
Annual Meeting. Any shareholder may attend the Annual Meeting, whether or not he
or she has previously given a proxy.
 
     The solicitation of proxies for the Annual Meeting will be made primarily
by mail. However, if necessary to ensure satisfactory representation at the
Annual Meeting, additional solicitation may take place in writing or by
telephone or personal interview by officers of the Fund, who will not receive
compensation from the Fund for such services. As the date of the meeting
approaches, if we have not received your proxies, you may receive a telephone
call from our proxy solicitor, Computershare Fund Services (formerly, Georgeson
Shareholder Communications, Inc.) ("CFS"), which has been retained to assist
shareholders in the voting process. For these services, the Fund will pay CFS a
fee that is not expected to exceed $2,000. The Fund will reimburse brokers and
other nominees, in accordance with New York Stock Exchange approved
reimbursement rates, for their expenses in forwarding solicitation material to
the beneficial owners of shares of the Fund. All expenses incurred in connection
with the solicitation of proxies, including the services of CFS, will be borne
by the Fund.
 
                                        2

 
     Abstentions and "broker non-votes" (i.e., shares held by brokers or
nominees as to which (i) instructions have not been received from the beneficial
owners or the persons entitled to vote and (ii) the broker or nominee does not
have discretionary voting power on a particular matter) will be counted as
shares present for purposes of determining whether a quorum is present, but will
not be counted as having been voted on the matter in question. Assuming that a
quorum would otherwise be present, abstentions and broker non-votes will
accordingly have no effect for the purpose of determining whether a Trustee has
been elected, but will have the effect of a negative vote on Proposal 2.
 
     Randolph L. Kohn, Gregory B. McShea, Heidemarie Gregoriev and Richard C.
Sarhaddi, the persons named as proxies on the proxy card accompanying this Proxy
Statement, were selected by the Board of Trustees to serve in such capacity.
Messrs. Kohn, McShea and Sarhaddi and Ms. Gregoriev are each officers of the
Fund, and Mr. Kohn is also a Trustee of the Fund. Each executed and returned
proxy will be voted in accordance with the directions indicated thereon or, if
no direction is indicated, such proxy will be voted for the election as Trustees
of the Board of Trustees' nominees listed in this Proxy Statement and, if
applicable, for approval of an amendment to the Fund's Bylaws relating to the
election of Trustees by the holders of the Fund's outstanding preferred shares.
Discretionary authority is provided in the proxy as to any matters not
specifically referred to therein. The Board of Trustees is not aware of any
other matters which are likely to be brought before the Annual Meeting. However,
if any such matters properly come before the Annual Meeting, the persons named
in the proxy are fully authorized to vote thereon in accordance with their
judgment and discretion. In matters other than the election of Trustees and
approval of an amendment to the Fund's Bylaws, except where a different vote is
required by any provision of law or the Fund's Declaration of Trust or Bylaws, a
plurality of a quorum of the Shares necessary for the transaction of business at
a shareholders' meeting shall decide any question.
 
                                   PROPOSAL 1
 
                              ELECTION OF TRUSTEES
 
     The Annual Meeting will constitute the second annual meeting of
shareholders of the Fund. In accordance with the Declaration of Trust, the
Trustees were divided into the following three classes (each a "Class") prior to
the initial public offering of the Common Shares: Class I, whose term will
expire at the Fund's 2007 annual meeting of shareholders; Class II, whose
initial term will expire at the Annual Meeting; and Class III, whose initial
term will expire at the Fund's 2006 annual meeting of shareholders. At each
annual meeting beginning with the Annual Meeting, successors to the Class of
Trustees whose term expires at that annual meeting shall be elected for a
three-year term.
 
                                        3

 
     The following table sets forth the nominees who will stand for election at
the Annual Meeting, the Class of Trustees to which they have been designated and
the expiration of their terms if elected:
 


NOMINEE                                            CLASS     EXPIRATION OF TERM IF ELECTED*
-------                                           --------   ------------------------------
                                                       
Peter C. Erichsen...............................  Class II        2008 Annual Meeting
Ronald A. Nyberg................................  Class II        2008 Annual Meeting

 
---------------
 
* A Trustee shall hold office until the annual meeting for the year in which his
  or her term expires and until his or her successor shall be elected and shall
  qualify, subject, however, to prior death, resignation, retirement,
  disqualification or removal from office.
 
     Under the Fund's classified Board structure, ordinarily only those Trustees
in a single Class may be replaced in any one year, and it would require a
minimum of two years to change a majority of the Board of the Fund under normal
circumstances. This structure, which may be regarded as an "anti-takeover"
measure, may make it more difficult for the Fund's shareholders to change the
majority of Trustees of the Fund and, thus, promotes the continuity of
management.
 
     It is the intention of the persons designated as proxies in the proxy card,
unless otherwise directed therein, to vote at the Annual Meeting for the
election of Messrs. Erichsen and Nyberg. Each of the nominees has agreed to
serve if elected at the Annual Meeting. If either nominee is unable or
unavailable to serve, the persons named in the proxies will vote the proxies for
such other person as the Board of Trustees may recommend.
 
     Information Regarding the Trustees.  Information about the Trustees and
nominees is set forth below. The address of each Trustee and nominee is c/o the
Fund at its principal business address (385 East
 
                                        4

 
Colorado Boulevard, Pasadena, California 91101). Of the individuals listed
below, only Messrs. Erichsen and Nyberg are nominees for election at the Annual
Meeting.

     Audit Committee.  The Board of Trustees has established an Audit Committee
composed solely of Trustees who are not "interested persons" (as defined in the
1940 Act) of the Fund or the Investment Adviser, consisting of Messrs. Erichsen,
Larson, Nyberg and Toupin. Each member of the Audit Committee is "independent,"
as independence for audit committee members is defined in the currently
applicable listing standards of the New York Stock Exchange, on which the Common
Shares of the Fund are listed and traded. The Audit Committee provides oversight
with respect to the accounting and financial reporting policies and procedures
of the Fund and, among other things, considers the selection of independent
public accountants for the Fund and the scope of the audit and approves services
proposed to be performed by those accountants on behalf of the Fund and, under
certain circumstances, the Investment Adviser and certain affiliates. The
Trustees have adopted a written charter for the Audit Committee, a copy of which
was attached as Appendix A to the Fund's proxy statement dated March 31, 2004.
 
     The Audit Committee of the Fund has submitted the following report:
 
     The Audit Committee has reviewed and discussed with management of the Fund
the audited financial statements for the last fiscal year. The Audit Committee
has discussed with the Fund's independent accountants the matters required to be
discussed by Statements on Auditing Standards No. 61 (SAS 61). SAS 61 requires
independent accountants to communicate to the Audit Committee matters including,
if applicable: (1) methods used to account for significant unusual transactions;
(2) the effect of significant accounting policies in controversial or emerging
areas for which there is a lack of authoritative guidance or consensus; (3) the
process used by management in formulating particularly sensitive accounting
estimates and the basis for the accountant's conclusions regarding the
reasonableness of those estimates; and (4) disagreements with management over
the application of accounting principles and certain other matters. The Audit
Committee has received the written disclosures and the letter from the Fund's
independent accountants required by Independence Standards Board Standard No. 1
(requiring accountants to make written disclosures to and discuss with the Audit
Committee various matters relating to the accountants' independence), and has
discussed with such accountants the independence of such accountants. Based on
the foregoing review and discussions, the Audit Committee recommended to the
Trustees
 
                                        13

 
the inclusion of the audited financial statements for the last fiscal year in
the Fund's annual report to shareholders.
 
                                          Ronald E. Toupin (Chairman)
                                          Peter C. Erichsen
                                          Michael Larson
                                          Ronald A. Nyberg
 
     Governance and Nominating Committee.  The Board of Trustees has established
a Governance and Nominating Committee composed solely of Trustees who are not
"interested persons" (as defined in the 1940 Act) of the Fund or the Investment
Adviser, consisting of Messrs. Erichsen, Larson, Nyberg (Chairman) and Toupin.
The Governance and Nominating Committee meets to select nominees for election as
Trustees of the Fund and consider other matters of Board policy. The Trustees
have adopted a written charter for the Governance and Nominating Committee, a
copy of which was included as Appendix B to the Fund's proxy statement dated
March 31, 2004. The Fund does not currently maintain a website on which the
charter is made available.
 
     The Governance and Nominating Committee requires that Trustee candidates
have a college degree or equivalent business experience, but has not otherwise
established specific, minimum qualifications that must be met by an individual
to be considered by the Committee for nomination as a Trustee. The Governance
and Nominating Committee may take into account a wide variety of factors in
considering Trustee candidates, including, but not limited to: (i) availability
and commitment of a candidate to attend meetings and perform his or her
responsibilities to the Board of Trustees, (ii) relevant industry and related
experience, (iii) educational background, (iv) financial expertise, (v) an
assessment of the candidate's ability, judgment and expertise and (vi) overall
diversity of the Board's composition. The Governance and Nominating Committee
may consider candidates for Trustee recommended by the Fund's current Trustees,
officers, Investment Adviser, shareholders or any other source deemed to be
appropriate by the Governance and Nominating Committee. Candidates properly
submitted by shareholders (as described below) will be considered and evaluated
on the same basis as candidates recommended by other sources.
 
     The policy of the Governance and Nominating Committee is to consider
nominees recommended by shareholders to serve as Trustee, provided that any such
recommendation is submitted in writing to the Fund, to the attention of the
Secretary, at the address of the principal executive offices of the Fund, not
less than one hundred and twenty calendar days nor more than one hundred and
thirty-five calendar days prior to the date of the meeting at which the nominee
would be elected and that such shareholder recommendation contains the
information about such nominee required by the Fund's procedures for
shareholders to submit nominee candidates, which are a part of the Governance
and Nominating Committee's Charter.
 
                                        14

 
The Governance and Nominating Committee has full discretion to reject nominees
recommended by shareholders, and there is no assurance that any such person so
recommended and considered by the Governance and Nominating Committee will be
nominated for election to the Fund's Board of Trustees.
 
     Meetings.  During 2004, the Board of Trustees held six meetings, the Audit
Committee held five meetings and the Governance and Nominating Committee held
three meetings. Each Trustee attended each of the meetings of the Board of
Trustees and the Committees of the Board of Trustees on which he served. The
Fund's policies require the Trustees to attend the Fund's annual shareholder
meetings, and annual meetings are generally expected to be held in connection
with regularly scheduled meetings of the Board of Trustees in order to
facilitate attendance. Each Trustee attended the Fund's annual shareholder
meeting in May 2004.
 
     Shareholder Communications.  The Board of Trustees provides a process for
shareholders to send communications to the Board of Trustees. Shareholders may
mail written communications to the attention of the Board of Trustees, care of
the Fund's Secretary, at the Fund's shareholder servicing agent, Claymore
Securities, Inc., 2455 Corporate West Drive, Lisle, Illinois 60532. The written
communication must include the shareholder's name, be signed by the shareholder,
refer to the Fund, and include the class and number of shares held by the
shareholder as of a recent date.
 
     Trustee Compensation.  Trustees of the Fund who are affiliated persons of
the Fund, the Investment Adviser, or Claymore Securities, Inc. receive no salary
or fees from the Fund. Effective February 2005, each other Trustee of the Fund
receives a fee of $15,000 annually for serving as a Trustee of the Fund, and a
fee of $1,000 and related expenses for each meeting of the Board of Trustees
attended. The Chairman of the Board of Trustees receives an additional $2,000
per year for serving in that capacity. Audit Committee members receive $500 for
each meeting, and the Audit Committee Chairman receives an additional $1,500
annually. Other committee members receive $500 per meeting.
 
                                        15

election of Mr. Nyberg and present in person or represented by proxy at the

elect Messrs. Erichsen and Nyberg to the Board of Trustees.

                                   PROPOSAL 2
 
                      PROPOSAL TO AMEND THE FUND'S BYLAWS
 
     The Trustees of the Fund are proposing to amend a provision of the Fund's
Bylaws regarding the election of Trustees by Preferred Shareholders. The 1940
Act requires that at least two Trustees of the Fund be elected by Preferred
Shareholders (the "Preferred Share Trustees"). The remainder of the Trustees
must be elected by the Common Shareholders and Preferred Shareholders voting
together as a class. The Bylaws currently provide that the Preferred
Shareholders shall be entitled, as a class, and to the exclusion of the Common
Shareholders, to elect two Trustees of the Fund at any meeting of shareholders
of the Fund held for the election of Trustees. This provision of the Bylaws was
intended to comply with the 1940 Act's requirements regarding the election of
Preferred Share Trustees. However, because of the Fund's classified board
structure, not all Trustees of the Fund stand for re-election at each annual
meeting. Accordingly, there is a potential ambiguity in the Bylaws as to whether
(i) Preferred Shareholders, as a class and to the exclusion of the Common
Shareholders, elect only the Preferred Share Trustees or (ii) the Preferred
Shareholders elect two Trustees standing for election at each meeting, as a
class and to the exclusion of the Common Shareholders, regardless of whether or
not such Trustees have been designated as Preferred Share Trustees. The proposed
amendment to the Bylaws would clarify that the Preferred Shareholders are
entitled, as a class and to the exclusion of the Common Shareholders, to elect
only the two Preferred Share Trustees. A Trustee not designated as a Preferred
Share Trustee would be elected by the Common Shareholders and Preferred
Shareholders voting together as a class, which is consistent with applicable law
and the intent of the Bylaws.
 
     A copy of the proposed amendment to the Bylaws is attached to this Proxy
Statement as Appendix A. For a more complete understanding of Proposal 2,
Preferred Shareholders should review Appendix A.
 
     Required Vote.  Approval of Proposal 2 will require the affirmative vote of
a majority of the Fund's Preferred Shares, which means the affirmative vote of
the lesser of (1) 67% of the Preferred Shares that are present at the Annual
Meeting, if the holders of more than 50% of the Preferred Shares outstanding as
of the Record Date are present or represented by proxy at the Annual Meeting, or
(2) more than 50% of the Preferred Shares outstanding on the Record Date. If the
vote required to approve Proposal 2 is not obtained, the Fund's Bylaws will not
be changed and Trustees will consider what other actions to take in the best
interests of the Fund. The Trustees unanimously recommend that shareholders vote
for Proposal 2.

                 SHAREHOLDER PROPOSALS FOR 2006 ANNUAL MEETING
 
     Proposals that shareholders wish to present to the 2006 Annual Meeting and
to have included in the Fund's proxy materials relating to such meeting must be
delivered to the Secretary of the Fund not less than 120 days prior to
[          ], 2006.
 
     Shareholders who wish to make a proposal at the 2006 Annual
Meeting -- other than one that will be included in the Fund's proxy
materials -- should notify the Fund not less than 45 days prior to [          ],
2006.
 
     Shareholders who wish to propose one or more nominees for election as
Trustees, or to make another proposal, at the 2006 annual meeting must provide
written notice to the Fund (including all required information) so that such
notice is received in good order by the Fund no earlier than 45 days prior to
[          ], 2006 and no later than 60 days prior to [          ], 2006.
 
     The proper submission of a shareholder proposal does not guarantee that it
will be included in the Fund's proxy materials or presented at a shareholder
meeting. Shareholder proposals are subject to the requirements of applicable law
and the Fund's Declaration of Trust and Bylaws.
 
            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, as amended (the "Exchange Act"), require the Fund's officers and
Trustees, the Investment Adviser, certain affiliates of the Investment Adviser,
and persons who beneficially own more than ten percent of a registered class of
the Fund's equity securities, among others, to file reports of ownership and
changes in ownership with the Securities and Exchange Commission ("SEC") and the
New York Stock Exchange. These persons are required by SEC regulation to furnish
the Fund with copies of all Section 16(a) forms they file.
 
     Based solely on its review of the copies of such forms received by it, or
written representations from certain reporting persons, the Fund believes that,
during 2004, all such filing requirements were met, with the exception that, due
to an administrative oversight, Mr. Erichsen made one late filing on Form 4 with
respect to a previously unreported purchase of Common Shares.
 
                         ANNUAL REPORT TO SHAREHOLDERS
 
     The Fund's Annual Report to Shareholders for the fiscal year ended December
31, 2004 contains financial and other information pertaining to the Fund. The
Fund will furnish without charge to each person whose proxy is being solicited,
upon request of such person, a copy of the Annual Report to Shareholders.

                            INDEPENDENT ACCOUNTANTS
 
     The Audit Committee of the Board of Trustees has selected
PricewaterhouseCoopers LLP as the independent public accountants of the Fund for
the fiscal year ending December 31, 2005, and the Board of Trustees, including a
majority of the Trustees who are not "interested persons" (as defined in the
1940 Act) of the Fund, has unanimously ratified such selection.
PricewaterhouseCoopers LLP's service is subject to termination by a majority of
the outstanding Shares of the Fund. Representatives of PricewaterhouseCoopers
LLP are currently expected to attend the meeting, and may, as they see fit, make
a statement and/or respond to appropriate questions.
 
     The following table presents fees billed in each of the Fund's last two
fiscal years for services rendered to the Fund by PricewaterhouseCoopers LLP:
 


FISCAL YEAR ENDED    AUDIT FEES   AUDIT-RELATED FEES   TAX FEES   ALL OTHER FEES
-----------------    ----------   ------------------   --------   --------------
                                                      
December 31, 2003*    $59,000          $14,000          $4,200          $0
December 31, 2004     $25,100          $ 6,400          $  900          $0

 
---------------
 
* The Fund's initial fiscal year was from September 30, 2003 through December
  31, 2003.
 
     "Audit Fees" represents fees billed for each of the last two fiscal years
for professional services rendered for the audit of the Fund's financial
statements for those fiscal years (the Fund's seed financial statements during
the initial fiscal year) or services that are normally provided by the
accountant in connection with statutory or regulatory filings or engagements for
that fiscal year.
 
     "Audit Related Fees" represents fees billed for each of the last two fiscal
years for assurance and related services reasonably related to the performance
of the audit of the Fund's annual financial statements for that year, including
a review of rating agency compliance testing for the Fund's Preferred Shares.
 
     "Tax Fees" represents fees billed for the each of the last two fiscal years
for professional services related to tax compliance, tax advice and tax
planning, including preparation of federal and state income tax returns and
preparation of excise tax returns.
 
     "All Other Fees" represents fees, if any, billed for other products and
services rendered by PricewaterhouseCoopers LLP to the Fund for the last two
fiscal years.
 
     For the Fund's fiscal years ended December 31, 2003 and December 31, 2004,
PricewaterhouseCoopers LLP billed aggregate non-audit fees in the amounts of
$883,350 and $372,631, respectively, to the
 
                                        26

 
Fund, the Investment Adviser and any entity controlling, controlled by or under
common control with the Investment Adviser that provides ongoing services to the
Fund.
 
     Pre-Approval Policies of the Audit Committee.  The Audit Committee has
determined that all work performed for the Fund by PricewaterhouseCoopers LLP
will be pre-approved by the full Audit Committee and, therefore, has not adopted
pre-approval procedures. Since the Fund's inception in August 2003, all audit
and non-audit services performed by PricewaterhouseCoopers LLP for the Fund, and
all non-audit services performed by PricewaterhouseCoopers LLP for the
Investment Adviser and any entity controlling, controlled by or under common
control with the Investment Adviser that provides ongoing services to the Fund
(a "Service Affiliate"), to the extent that such services related directly to
the operations and financial reporting of the Fund, have been pre-approved by
the Audit Committee. No "Audit-Related Fees," "Tax-Fees" and "Other Fees" set
forth in the table above were waived pursuant to 17 CFR 210.2-01(c)(7)(i)(c).
 
     PricewaterhouseCoopers LLP did not bill any fees for non-audit services
that required pre-approval by the Audit Committee pursuant to paragraph
(c)(7)(ii) of Rule 2-01 of Regulation S-X during the Fund's fiscal years ended
December 31, 2003 and December 31, 2004.
 
     The Audit Committee has considered whether the provision of the non-audit
services rendered by PricewaterhouseCoopers LLP since the Fund's inception to
the Investment Adviser and any Service Affiliate that were not required to be
pre-approved by the Audit Committee pursuant to paragraph (c)(7)(ii) of Rule
2-01 of Regulation S-X is compatible with maintaining the independence of
PricewaterhouseCoopers LLP.
 
                                  ADJOURNMENT
 
     In the absence of a quorum at the Annual Meeting, or (even if a quorum is
present) if sufficient votes in favor of a proposal set forth in the Notice of
Annual Meeting are not received by the time scheduled for the Annual Meeting,
the persons named as proxies may propose one or more adjournments of the Annual
Meeting after the date set for the original Annual Meeting, with no other notice
than announcement at the Annual Meeting, to permit further solicitation of
proxies with respect to such proposal. In addition, if, in the judgment of the
persons named as proxies, it is advisable to defer action on a proposal, the
persons named as proxies may propose one or more adjournments of the Annual
Meeting with respect to such proposal for a reasonable time. Any adjournments
with respect to a proposal will require the affirmative vote of a plurality of
the Shares of the Fund entitled to vote thereon present in person or represented
by proxy at the session of the Annual Meeting to be adjourned. The persons named
as proxies will vote in favor of such adjournment those proxies which they are
entitled to vote in favor of the proposal in question. They will vote against
any such adjournment those proxies required to be voted against such proposal.
The costs
 
                                        27

 
of any additional solicitation and of any adjourned session will be borne by the
Fund. Any proposals for which sufficient favorable votes have been received by
the time of the Annual Meeting may be acted upon and, if so, such action will be
final regardless of whether the Annual Meeting is adjourned to permit additional
solicitation with respect to any other proposal.
 
                                 OTHER BUSINESS
 
     The Fund is not aware of any other matters to be presented for action at
the Annual Meeting. However, if any such other matters are properly presented,
it is the intention of the persons designated in the enclosed proxy to vote in
accordance with their best judgment.
 
                                          By Order of the Board of Trustees

                           PROTECTED SECURITIES FUND
 
      PROPOSED AMENDMENT TO THE FUND'S SECOND AMENDED AND RESTATED BYLAWS
 
Article 12, Part I, Section 4(a) of the Bylaws currently provides:
 
     "One Vote Per Share of Preferred Shares.  Except as otherwise provided
     herein or in the Declaration of Trust or as otherwise required by law, (i)
     each Holder of Preferred Shares shall be entitled to one vote for each
     share of Preferred Shares held by such Holder on each matter submitted to a
     vote of shareholders of the Trust, and (ii) the holders of outstanding
     preferred shares, including each share of the Preferred Shares, and of
     Common Shares shall vote together as a single class; provided, however,
     that, at any meeting of the shareholders of the Trust held for the election
     of Trustees, the holders of outstanding preferred shares, including the
     Preferred Shares, represented in person or by proxy at said meeting shall
     be entitled, as a class, to the exclusion of the holders of all other
     securities and classes of shares of beneficial interest of the Trust, to
     elect two Trustees of the Trust, each Preferred Share entitling the holder
     thereof to one vote. Subject to paragraph 4(b) of this Part I, the holders
     of outstanding Common Shares and preferred shares, voting together as a
     single class, shall elect the balance of the Trustees."
 
     If Proposal 2 is approved by the affirmative vote of the lesser of (1) 67%
of the Preferred Shares that are present at the Annual Meeting, if the holders
of more than 50% of the Preferred Shares outstanding as of the Record Date are
present or represented by proxy at the Annual Meeting, or (2) more than 50% of
the Preferred Shares outstanding on the Record Date, Article 12, Part I, Section
4(a) of the Bylaws will be amended to read as follows:
 
     "One Vote Per Share of Preferred Shares.  Except as otherwise provided
     herein or in the Declaration of Trust or as otherwise required by law, (i)
     each Holder of Preferred Shares shall be entitled to one vote for each
     share of Preferred Shares held by such Holder on each matter submitted to a
     vote of shareholders of the Trust, and (ii) the holders of outstanding
     preferred shares, including each share of the Preferred Shares, and of
     Common Shares shall vote together as a single class; provided, however,
     that, at any meeting of the shareholders of the Trust held for the election
     of Trustees, the holders of outstanding preferred shares, including the
     Preferred Shares, represented in person or by proxy at said meeting shall
     be entitled, as a class, to the exclusion of the holders of all other
     securities and classes of shares of beneficial interest of the Trust, to
     elect a number of Trustees (which number may be zero) such that,
     immediately following such meeting, two Trustees of the Trust shall have
     been elected
                                       A-1

 
     exclusively by holders of outstanding preferred shares, including the
     Preferred Shares (whether at such meeting, at a prior meeting of the
     shareholders, or at such meeting or a prior meeting of the shareholders
     with respect to one such Trustee and at a separate prior meeting of the
     shareholders with respect to the other such Trustee), each Preferred Share
     entitling the holder thereof to one vote. Subject to paragraph 4(b) of this
     Part I, the holders of outstanding Common Shares and preferred shares,
     voting together as a single class, shall elect the balance of the
     Trustees."
