                                 PROXY STATEMENT
                                       FOR
                     THE 2005 ANNUAL MEETING OF SHAREHOLDERS
                                       OF
                          CASTLE CONVERTIBLE FUND, INC.
                         TO BE HELD ON DECEMBER 6, 2005

                                  INTRODUCTION

       The  accompanying  Proxy is being  solicited by the Board of Directors of
Castle  Convertible  Fund,  Inc.  (the "Fund") for use at the Annual  Meeting of
Shareholders  to be  held  at  12:30  P.M.  on  December  6,  2005  and  at  any
adjournments thereof.

       If the  enclosed  Proxy is properly  executed  and returned in time to be
voted at the meeting,  the full and  fractional  shares  represented  (each full
share  is  entitled  to one  vote  and each  fractional  share  is  entitled  to
proportionate  voting rights) will be voted in accordance with the  instructions
marked.  Unless instructions to the contrary are marked with respect to Proposal
1, the Proxy will be voted FOR the proposal stated in the accompanying Notice of
Meeting.  Proxies not voted,  including  broker  non-votes,  will not be counted
toward  establishing a quorum. A broker non-vote is deemed to exist when a proxy
received  from a  broker  indicates  that a broker  does not have  discretionary
authority to vote the shares on the matter.  Shareholders should note that while
votes to  ABSTAIN  will  count  toward  establishing  a quorum,  passage  of any
proposal being considered at the meeting will occur only if a sufficient  number
of votes are cast FOR the  proposal.  Accordingly,  votes to  ABSTAIN  and votes
AGAINST  will have the same  effect  in  determining  whether  the  proposal  is
approved.  On any motion for  adjournment  of the  meeting,  even if a quorum is
present, the Proxy holders will vote all Proxies in their discretion pursuant to
Item 2. Any  shareholder  giving a Proxy has the right to attend the  meeting to
vote his or her  shares in person  (revoking  any prior  Proxy) and also has the
right to revoke the Proxy at any time by  written  notice  received  by the Fund
prior to its exercise.

       All costs of solicitation,  including  printing and mailing of this Proxy
Statement and the accompanying Notice of Meeting and Proxy, the reimbursement of
brokerage  firms  and  others  for their  expenses  in  forwarding  solicitation
material to the beneficial owners of stock, and  supplementary  solicitations to
submit  proxies,  which  may be made by mail,  telephone,  telegraph,  email and
personal  interviews  by officers of the Fund,  will be borne by the Fund. It is
anticipated that the cost of such  supplementary  solicitation,  if any, will be
nominal.

       This  Proxy  Statement  and  accompanying   Proxy  are  being  mailed  to
shareholders  on or  about  October  31,  2005.  The  address  of the  principal
executive office of the Fund is 111 Fifth Avenue, New York, NY 10003.

       Messrs.  Alger and Chung are  "interested  persons"  (as  defined  in the
Investment  Company  Act) of the Fund because of their  affiliations  with Alger
Management.  Mr. Chung is Mr. Alger's  son-in-law.  Ms. Alger, a daughter of Mr.
Alger, is an "interested  person"  because she is an immediate  family member of
Mr.  Alger.  No Director is a director  of any public  company  except as may be
indicated under "Principal Occupations."

       No director,  officer or employee of Alger  Management or its  affiliates
receives any compensation from the Fund for serving as an officer or Director of
the Fund.  The Fund pays each  non-interested  Director  $2,000 for each meeting
attended,  to a maximum of $8,000,  plus travel expenses  incurred for attending
the meeting.

       The Fund did not offer its Directors  any pension or retirement  benefits
during or prior to the fiscal year ended October 31, 2004.  The following  table
provides  compensation amounts paid to current  non-interested  Directors of the
Fund for the fiscal year ended October 31, 2004.

       Four regular  meetings and one special  meeting of the Board of Directors
were held during the fiscal year ended October 31, 2004. During that period each
of the Directors  attended at least 75% of the meetings of the Board, and of the
Audit Committee if he was a member, held during that time.

       The Fund's Audit  Committee,  which  oversees the Fund's  accounting  and
financial  reporting  policies  and  the  independent  audit  of  its  financial
statements,  met five times during the fiscal year ended  October 31, 2004.  The
Fund's Board of Directors  has no nominating  or  compensation  committee or any
committee performing similar functions.

       The Board of Directors  recommends  that  shareholders  vote FOR Proposal
No. 1.

NOMINATIONS OF DIRECTORS

       The Fund does not have a standing nominating committee. The Directors who
are not  "interested  persons" of the Fund as defined in the Investment  Company
Act of 1940,  as  amended,  each of whom is also  "independent"  as  defined  in
Section 121A of the Listing  Requirements  of the American  Stock  Exchange (the
"Independent   Directors")   are  responsible  for  identifying  and  nominating
candidates for appointment as Directors. The Board believes that the Independent
Directors are in the best position to screen and select qualified candidates for
Board membership who will provide the experience,  perspective, skills and other
attributes  necessary  to  effectively  advance  the  interests  of  the  Fund's
shareholders.   In  screening  and  selecting  qualified  candidates  for  Board
membership,  the  Independent  Directors may consider  suggestions  from various
sources,  including  shareholders.  Shareholders  may submit  names of potential
candidates  for  nomination  by  letter   addressed  to  the  attention  of  the
Independent Directors,  c/o the Secretary of the Fund. The Independent Directors
may also consider candidates recommended by Fred Alger Management, Inc., and may
retain an executive

                                       7



search firm and/or outside legal,  financial or other external counsel that they
deem  necessary  or  desirable  to assist  in the  nominating  and/or  screening
process.

SHAREHOLDER COMMUNICATIONS WITH DIRECTORS

       Shareholders  wishing to communicate  with the Directors may address such
communications  to the  Board  of  Directors,  c/o the  Secretary  of the  Fund,
specifying   an   individual   Director  by  name  if   appropriate.   All  such
communications are relayed to Board members.

DIRECTOR ATTENDANCE AT ANNUAL SHAREHOLDER MEETINGS

       The Fund does not have a policy  regarding  attendance  by  Directors  at
annual shareholder meetings. No Directors attended the 2004 Annual Meeting.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

       Section  16(a) of the 1934 Act and Section  30(h) of the 1940 Act require
the Fund's  Officers  and  Director's,  certain  Officers  and  Directors of the
investment adviser,  affiliated persons of the investment  adviser,  and persons
who  beneficially  own more than 10% of the  Fund's  shares to file  reports  of
ownership with the SEC and the Fund.

       Based solely upon its review of the copies of such forms  received by it,
the Fund believes  that,  for the fiscal year ended October 31, 2005, all filing
requirements applicable to such persons were compiled with.

                       AUDIT COMMITTEE REPORT; AUDIT FEES

       AUDIT  COMMITTEE  REPORT.  The  Audit  Committee,  for which the Board of
Directors  has adopted a written  charter,  (a)  selects,  oversees and sets the
compensation  of the  Fund's  independent  auditors,  (b)  oversees  the  Fund's
accounting  and  financial  reporting  policies  and  practices  and the  Fund's
internal  controls and (c) oversees  the quality and  objectivity  of the Fund's
financial  statements and the independent audit thereof.  At its meeting held on
December 7, 2004, the Committee  reviewed and discussed with Fund management and
Ernst & Young, the Fund's independent  registered public accounting firm for the
fiscal year ended October 31, 2004, the audit of the Fund's financial statements
and  further  discussed  with  Ernst  & Young  certain  matters  required  to be
discussed by  Statements on Auditing  Standards  No. 61. The Committee  received
from Ernst & Young written  disclosures  and the letter required by Independence
Standards  Board  Standard  No. 1 and  discussed  with Ernst & Young that firm's
independence.  Based on these reviews and discussions, the Committee recommended
to the Board that the  audited  financial  statements  be included in the Fund's
Annual Report to shareholders for the fiscal year ended October 31, 2004.

       The members of the Audit Committee are Lester L. Colbert, Jr., Stephen E.
O'Neil and Nathan E.  Saint-Amand.  None of the members of the  Committee  is an
"interested  person"  of the Fund and each is  "independent"  as  defined in the
listing standards of the American Stock Exchange.

       A  representative  of  Ernst & Young is  expected  to be  present  at the
meeting to respond to appropriate  questions;  the representative  will have the
opportunity to make a statement if he or she desires to do so.

       AUDIT FEES. The following table sets forth the fees paid to Ernst & Young
for the fiscal years ended October 31, 2003 and 2004 for  professional  services
rendered for the audit of the Fund's financial statements for those fiscal years
and other services.

                                       9



All  services  to be  performed  by the  Fund's  independent  registered  public
accounting firm must be pre-approved by the Fund's Audit Committee. Accordingly,
all of the  services  represented  in the table were  pre-approved  by the Audit
Committee.  Ernst & Young LLP performed no services for Alger  Management or any
entity controlling,  controlled by or under common control with Alger Management
during the fiscal  years ended  October 31, 2003 and 2004.  Aggregate  non-audit
fees  billed by Ernst & Young for the fiscal  years  ended  October 31, 2003 and
2004 were $15,150 and $19,000, respectively.

                                   LITIGATION

Alger Management has responded to inquiries, document requests and/or
subpoenas from regulatory authorities, including the United States Securities
and Exchange Commission ("SEC"), the Office of the New York State Attorney
General, the Attorney General of New Jersey, and the West Virginia Securities
Commissioner, in connection with their investigations of practices in the mutual
fund industry identified as "market timing" and "late trading."

         On August 31, 2005, the West Virginia Securities Commissioner in an EX
PARTE Summary Order to Cease and Desist and Notice of Right to Hearing concluded
that Alger Management and Alger Inc. had violated the West Virginia Uniform
Securities Act, and ordered Alger Management and Alger Inc. to cease and desist
from further violations of the Act by engaging in the market-timing related
conduct described in the order. The EX PARTE order provided notice of their
right to a hearing with respect to the violations of law asserted by the
Commissioner. Other firms unaffiliated with Alger Management were served with
similar orders. Alger Management and Alger Inc. intend to request a hearing for
the purpose of seeking to vacate or modify the order.

         In addition, several purported class actions and shareholder derivative
suits, and a civil lawsuit by the West Virginia attorney general, have been
filed against various parties in the mutual fund industry, including Alger
Management, certain mutual funds managed by Alger Management (the "Alger Mutual
Funds"), and certain current and former Alger Mutual Fund trustees and officers,
alleging wrongful conduct related to market-timing and late-trading by mutual
fund shareholders. These cases have been transferred to the U.S. District Court
of Maryland by the Judicial Panel on Multidistrict Litigation for consolidated
pre-trial proceedings. In September 2004, consolidated amended complaints
involving these cases (not yet including the West Virginia action)-- a
Consolidated Amended Fund Derivative Complaint (the "Derivative Complaint") and
two substantially identical Consolidated Amended Class Action Complaints
(together, the "Class Action Complaint") -- were filed in the Maryland federal
district court under the caption number 1:04-MD-15863 (JFM). The civil cases
remain pending.

         The Derivative Complaint alleges (i) violations, by Alger Management
and, depending on the specific offense alleged, by its immediate parent, Alger
Inc., which is the Distributor of the Alger Mutual Funds, and/or the fund
trustee defendants, of Sections 36(a), 36(b), 47, and 48 of the Investment
Company Act of 1940 and of Sections 206 and 215 of the Investment Advisers Act
of 1940, breach of fiduciary duty, and breach of contract, (ii) various offenses
by other third-party defendants, and (iii) unjust enrichment by all the named
defendants. The Class Action Complaint alleges, in addition to the offenses
listed above, (i) violations, by Alger Management, Alger Inc., their affiliates,
the funds named as defendants, and the current and former fund trustees and
officers, of Sections 11, 12(a)(2), and 15 of the Securities Act of 1933,
Sections 10(b) (and Rule 10b-5 thereunder) and 20(a) of the Securities Exchange
Act of 1934, and Section 34(b) of the Investment Company Act of 1940, (ii)
breach of contract by the funds named as defendants, and (iii) unjust enrichment
of the defendants. The West Virginia attorney general action also alleges
violations of the West Virginia Consumer Credit and Protection Act and other
wrongful conduct. Motions to dismiss the Class Action Complaint and the
Derivative Complaint have been filed, but not yet decided. Rulings are expected
in or about early November 2005.

         Alger Management does not believe that the Alger Mutual Funds are
themselves targets of the regulatory investigations as potential enforcement
defendants. It is possible, however, that the actions of Alger Management and
certain of its affiliates and their senior executives and Alger Mutual Fund
senior personnel are of interest to the investigators. Although no regulatory
enforcement action has yet been commenced against Alger Management, board
members or personnel in connection with the matters being investigated (other
than the actions resolved in the fall of 2003 against James P. Connelly, Jr.,
former Vice Chairman of Alger Inc.), it is possible that the SEC and the states
may pursue actions in the future. The potential timing of any such action or the
relief or remedies that may be sought are not known at this time. Alger
Management is not yet able to predict the outcomes of these matters. The SEC
and, in some cases, state government authorities have a variety of
administrative and civil enforcement powers, including injunctive powers,
authority to assess fines and penalties and order restitution, authority to
limit the activities of a person or company and other enforcement powers, that
may be exercised administratively or through the courts.

         Under Section 9(a) of the Investment Company Act, if any of the various
regulatory proceedings or lawsuits were to result in a court injunction against
Alger Management or Alger Inc., Alger Management would, in the absence of
exemptive relief granted by the SEC, be barred from serving as investment
adviser/sub-adviser for any registered investment company, including the Fund.
While exemptive relief from Section 9(a) has been granted in certain other
cases, there is no assurance that such exemptive relief would be granted if
sought. In addition, it is possible that these matters and/or other developments
resulting from these matters could result in loss of Alger Management personnel,
diversion of time and attention of Alger Management personnel, diminishment of
financial resources of Alger Management, or other consequences potentially
adverse to the Fund. Alger Management cannot predict the potential effect of
such actions upon Alger Management or the Fund. There can be no assurance that
the effect, if any, would not be material.
