             THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.  ORGANIZATION.  The Gabelli  Convertible and Income Securities Fund Inc. (the
"Fund") is a diversified  closed-end  management  investment  company registered
under the  Investment  Company Act of 1940,  as amended (the "1940 Act"),  whose
investment  objective  is to  seek  a high  level  of  total  return  through  a
combination  of  current  income  and  capital   appreciation  by  investing  in
convertible  securities.  The Fund was  incorporated in Maryland on December 19,
1988 as a  diversified  open-end  management  investment  company and  commenced
investment  operations  on July 3, 1989 as The  Gabelli  Convertible  Securities
Fund,  Inc. The Board of Directors  (the  "Board"),  upon  approval at a special
meeting  of  shareholders  held on  February  17,  1995,  voted to  approve  the
conversion of the Fund to closed-end status, effective March 31, 1995.

      Effective  August  1,  2002,  the Fund  changed  its  name to The  Gabelli
Convertible and Income Securities Fund Inc.  Consistent with its new name, under
normal market conditions, the Fund will invest at least 80% of its net assets in
a combination of convertible  securities and income  producing  securities  (the
"80%  Policy").  The Fund  expects to  continue  its  practice  of  focusing  on
convertible securities to the extent attractive opportunities are available. The
80% Policy may be changed without shareholder  approval.  However,  the Fund has
adopted a policy to provide  shareholders  with notice at least 60 days prior to
the implementation of any change in the 80% Policy.

2. SIGNIFICANT  ACCOUNTING POLICIES.  The preparation of financial statements in
accordance with United States ("U.S.") generally accepted accounting  principles
requires  management to make estimates and assumptions  that affect the reported
amounts and disclosures in the financial statements. Actual results could differ
from those  estimates.  The  following  is a summary of  significant  accounting
policies followed by the Fund in the preparation of its financial statements.

      SECURITY VALUATION.  Portfolio securities listed or traded on a nationally
recognized securities exchange or traded in the U.S. over-the-counter market for
which market quotations are readily available are valued at the last quoted sale
price or a market's  official  closing  price as of the close of business on the
day the  securities  are being  valued.  If there  were no sales  that day,  the
security is valued at the  average of the  closing  bid and asked  prices or, if
there were no asked  prices  quoted on that day,  then the security is valued at
the closing bid price on that day. If no bid or asked  prices are quoted on such
day,  the  security is valued at the most  recently  available  price or, if the
Board so determines,  by such other method as the Board shall  determine in good
faith to reflect its fair market value. Portfolio securities traded on more than
one national  securities exchange or market are valued according to the broadest
and most  representative  market,  as  determined  by  Gabelli  Funds,  LLC (the
"Adviser").

      Portfolio  securities  primarily  traded on a foreign market are generally
valued at the  preceding  closing  values  of such  securities  on the  relevant
market,  but may be fair valued pursuant to procedures  established by the Board
if market conditions change  significantly after the close of the foreign market
but prior to the close of business on the day the  securities  are being valued.
Debt  instruments  with  remaining  maturities  of 60 days or less  that are not
credit impaired are valued at amortized cost,  unless the Board  determines such
amount  does not  reflect  the  securities'  fair  value,  in which  case  these
securities  will be fair valued as  determined  by the Board.  Debt  instruments
having a maturity  greater than 60 days for which market  quotations are readily
available are valued at the average of the latest bid and asked prices. If there
were no asked  prices  quoted  on such day,  the  security  is valued  using the
closing bid price.  Futures contracts are valued at the closing settlement price
of the exchange or board of trade on which the applicable contract is traded.

      Securities  and  assets  for  which  market  quotations  are  not  readily
available  are  fair  valued  as  determined  by  the  Board.   Fair   valuation
methodologies  and procedures may include,  but are not limited to: analysis and
review of available  financial and non-financial  information about the company;
comparisons  to the  valuation  and changes in valuation of similar  securities,
including a comparison of foreign securities to the equivalent U.S. dollar value
ADR  securities at the close of the U.S.  exchange;  and evaluation of any other
information that could be indicative of the value of the security.

             THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

      REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements with
primary  government  securities dealers recognized by the Federal Reserve Board,
with  member  banks of the  Federal  Reserve  System,  or with other  brokers or
dealers that meet credit  guidelines  established by the Adviser and reviewed by
the Board.  Under the terms of a typical  repurchase  agreement,  the Fund takes
possession  of an  underlying  debt  obligation  subject to an obligation of the
seller to repurchase,  and the Fund to resell,  the obligation at an agreed-upon
price and time, thereby  determining the yield during the Fund's holding period.
The Fund will always receive and maintain  securities as collateral whose market
value, including accrued interest,  will be at least equal to 102% of the dollar
amount  invested by the Fund in each  agreement.  The Fund will make payment for
such  securities  only upon  physical  delivery  or upon  evidence of book entry
transfer of the collateral to the account of the  custodian.  To the extent that
any repurchase transaction exceeds one business day, the value of the collateral
is marked-to-market on a daily basis to maintain the adequacy of the collateral.
If the seller defaults and the value of the collateral declines or if bankruptcy
proceedings   are  commenced  with  respect  to  the  seller  of  the  security,
realization of the collateral by the Fund may be delayed or limited. At June 30,
2006, there were no open repurchase agreements.

      SWAP  AGREEMENTS.  The Fund  may  enter  into  interest  rate  swap or cap
transactions.  The use of swaps and caps is a highly  specialized  activity that
involves  investment  techniques and risks different from those  associated with
ordinary  portfolio  transactions.  Swap  agreements  may  involve,  to  varying
degrees,  elements  of market and  counterparty  risk,  and  exposure to loss in
excess  of  the  related  amounts  reflected  in the  Statement  of  Assets  and
Liabilities.  In an interest rate swap, the Fund would agree to pay to the other
party  to  the  interest  rate  swap  (which  is  known  as  the   counterparty)
periodically a fixed rate payment in exchange for the  counterparty  agreeing to
pay to the Fund  periodically  a  variable  rate  payment  that is  intended  to
approximate  the Fund's  variable rate payment  obligation on Series C Preferred
Stock. In an interest rate cap, the Fund would pay a premium to the counterparty
and, to the extent that a specified  variable rate index exceeds a predetermined
fixed rate,  would  receive from that  counterparty  payments of the  difference
based  on  the  notional  amount  of  such  cap.  Interest  rate  swap  and  cap
transactions  introduce  additional risk because the Fund would remain obligated
to pay  preferred  stock  dividends  when due in  accordance  with the  Articles
Supplementary even if the counterparty  defaulted.  If there is a default by the
counterparty  to a swap  contract,  the  Fund  will be  limited  to  contractual
remedies  pursuant to the  agreements  related to the  transaction.  There is no
assurance  that  the swap  contract  counterparties  will be able to meet  their
obligations  pursuant to a swap contract or that,  in the event of default,  the
Fund will succeed in pursuing  contractual  remedies.  The Fund thus assumes the
risk that it may be delayed in or prevented from  obtaining  payments owed to it
pursuant  to  a  swap  contract.  The  creditworthiness  of  the  swap  contract
counterparties is closely monitored in order to minimize this risk. Depending on
the general  state of  short-term  interest  rates and the returns on the Fund's
portfolio  securities  at that point in time,  such a default  could  negatively
affect  the Fund's  ability to make  dividend  payments  for Series C  Preferred
Stock. In addition, at the time an interest rate swap or cap transaction reaches
its scheduled  termination  date, there is a risk that the Fund will not be able
to obtain a replacement  transaction or that the terms of the  replacement  will
not be as  favorable as on the expiring  transaction.  If this occurs,  it could
have a negative impact on the Fund's ability to make dividend payments on Series
C Preferred Stock.

      Unrealized  gains related to swaps are reported as an asset and unrealized
losses are reported as a liability in the  Statement of Assets and  Liabilities.
The  change in value of swaps,  including  the  accrual of  periodic  amounts of
interest to be paid or received  on swaps is  reported  as  unrealized  gains or
losses in the Statement of Operations.  A realized gain or loss is recorded upon
payment or receipt of a periodic payment or termination of swap  agreements.  At
June 30, 2006, there were no open swap agreements.


                                       10


             THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

      FUTURES  CONTRACTS.  The Fund may  engage  in  futures  contracts  for the
purpose of hedging against changes in the value of its portfolio  securities and
in the value of securities it intends to purchase.  Upon entering into a futures
contract,  the Fund is required to deposit  with the broker an amount of cash or
cash equivalents equal to a certain  percentage of the contract amount.  This is
known as the "initial margin." Subsequent payments ("variation margin") are made
or received by the Fund each day,  depending  on the daily  fluctuations  in the
value    of    the    contract,     which    are    included    in    unrealized
appreciation/depreciation   on  investments  and  futures  contracts.  The  Fund
recognizes a realized gain or loss when the contract is closed.

      There are several risks in connection with the use of futures contracts as
a  hedging  instrument.  The  change  in value of  futures  contracts  primarily
corresponds  with the  value  of their  underlying  instruments,  which  may not
correlate with the change in value of the hedged investments. In addition, there
is the risk that the Fund may not be able to enter  into a  closing  transaction
because of an illiquid  secondary  market.  At June 30, 2006, there were no open
futures contracts.

      SECURITIES  SOLD SHORT.  The Fund may enter into short sale  transactions.
Short selling involves  selling  securities that may or may not be owned and, at
times,  borrowing the same  securities  for delivery to the  purchaser,  with an
obligation  to replace such borrowed  securities  at a later date.  The proceeds
received  from short sales are recorded as  liabilities  and the Fund records an
unrealized  gain or loss to the extent of the  difference  between the  proceeds
received  and the value of an open short  position on the day of  determination.
The Fund records a realized gain or loss when the short  position is closed out.
By entering into a short sale,  the Fund bears the market risk of an unfavorable
change in the price of the  security  sold short.  Dividends  on short sales are
recorded as an expense by the Fund on the ex-dividend  date and interest expense
is  recorded on the accrual  basis.  Securities  sold short at June 30, 2006 are
reported within the Schedule of Investments.

      FORWARD FOREIGN EXCHANGE CONTRACTS. The Fund may engage in forward foreign
exchange contracts for hedging a specific transaction with respect to either the
currency in which the  transaction is denominated or another  currency as deemed
appropriate by the Adviser. Forward foreign exchange contracts are valued at the
forward  rate and are  marked-to-market  daily.  The  change in market  value is
included in  unrealized  appreciation/depreciation  on  investments  and foreign
currency translations.  When the contract is closed, the Fund records a realized
gain or loss equal to the  difference  between the value of the  contract at the
time it was opened and the value at the time it was closed.

      The  use  of  forward  foreign  exchange   contracts  does  not  eliminate
fluctuations in the underlying prices of the Fund's portfolio securities, but it
does  establish a rate of exchange that can be achieved in the future.  Although
forward  foreign  exchange  contracts limit the risk of loss due to a decline in
the value of the hedged currency,  they also limit any potential gain that might
result should the value of the currency increase. In addition, the Fund could be
exposed to risks if the  counterparties  to the contracts are unable to meet the
terms of their  contracts.  At June 30, 2006, there were no open forward foreign
exchange contracts.

      FOREIGN  CURRENCY  TRANSLATIONS.  The  books and  records  of the Fund are
maintained in U.S. dollars.  Foreign currencies,  investments,  and other assets
and liabilities are translated into U.S.  dollars at the current exchange rates.
Purchases  and  sales  of  investment  securities,   income,  and  expenses  are
translated  at the exchange  rate  prevailing  on the  respective  dates of such
transactions.  Unrealized  gains and losses that result from  changes in foreign
exchange rates and/or changes in market prices of securities  have been included
in unrealized  appreciation/depreciation  on  investments  and foreign  currency
translations.  Net realized  foreign  currency  gains and losses  resulting from
changes in exchange  rates include  foreign  currency  gains and losses  between
trade date and settlement date on investment  securities  transactions,  foreign
currency  transactions,  and the difference  between the amounts of interest and
dividends  recorded on the books of the Fund and the amounts actually  received.
The  portion of foreign  currency  gains and losses  related to  fluctuation  in
exchange rates between the initial trade date and subsequent  sale trade date is
included in realized gain/(loss) on investments.


                                       11


             THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

      FOREIGN  SECURITIES.  The Fund may directly purchase securities of foreign
issuers.  Investing in securities of foreign issuers  involves special risks not
typically  associated  with investing in securities of U.S.  issuers.  The risks
include  possible  revaluation of currencies,  the ability to repatriate  funds,
less complete financial information about companies, and possible future adverse
political  and  economic  developments.  Moreover,  securities  of many  foreign
issuers and their markets may be less liquid and their prices more volatile than
those of securities of comparable U.S. issuers.

      FOREIGN TAXES.  The Fund may be subject to foreign taxes on income,  gains
on investments, or currency repatriation, a portion of which may be recoverable.
The Fund will accrue such taxes and  recoveries  as  applicable,  based upon its
current interpretation of tax rules and regulations that exist in the markets in
which it invests.

      RESTRICTED AND ILLIQUID  SECURITIES.  The Fund may invest up to 15% of its
net assets in securities for which the markets are illiquid. Illiquid securities
include  securities the disposition of which is subject to substantial  legal or
contractual  restrictions.  The sale of illiquid  securities often requires more
time and  results  in higher  brokerage  charges or dealer  discounts  and other
selling  expenses  than does the sale of  securities  eligible  for  trading  on
national securities  exchanges or in the  over-the-counter  markets.  Restricted
securities  may  sell at a price  lower  than  similar  securities  that are not
subject to  restrictions on resale.  Securities  freely saleable among qualified
institutional  investors  under  special  rules  adopted by the  Securities  and
Exchange  Commission  (the  "SEC")  may be  treated  as liquid  if they  satisfy
liquidity  standards  established by the Board. The continued  liquidity of such
securities  is not as well assured as that of publicly  traded  securities,  and
accordingly the Board will monitor their liquidity.

      SECURITIES TRANSACTIONS AND INVESTMENT INCOME. Securities transactions are
accounted  for on the  trade  date  with  realized  gain or loss on  investments
determined  by using the  identified  cost method.  Interest  income  (including
amortization  of premium and  accretion  of discount) is recorded on the accrual
basis.  Premiums  and  discounts  on debt  securities  are  amortized  using the
effective  yield  to  maturity  method.  Dividend  income  is  recorded  on  the
ex-dividend date except for certain  dividends which are recorded as soon as the
Fund is informed of the dividend.

      CUSTODIAN FEE CREDITS.  When cash  balances are  maintained in the custody
account,  the Fund receives credits which are used to offset custodian fees. The
gross expenses paid under the custody arrangement are included in custodian fees
in the Statement of Operations with the  corresponding  expense offset,  if any,
shown as "custodian fee credits".

      DISTRIBUTIONS  TO SHAREHOLDERS.  Distributions to common  shareholders are
recorded on the ex-dividend  date.  Distributions  to shareholders  are based on
income and capital gains as determined  in  accordance  with Federal  income tax
regulations,  which may differ from income and capital gains as determined under
U.S. generally accepted accounting  principles.  These differences are primarily
due to differing treatments of income and gains on various investment securities
and foreign currency  transactions  held by the Fund,  timing  differences,  and
differing  characterizations  of distributions  made by the Fund.  Distributions
from net  investment  income  include  net  realized  gains on foreign  currency
transactions.  These book/tax  differences are either  temporary or permanent in
nature. To the extent these  differences are permanent,  adjustments are made to
the appropriate capital accounts in the period when the differences arise. These
reclassifications have no impact on the net asset value ("NAV") of the Fund. For
the fiscal year ended December 31, 2005, reclassifications were made to increase
accumulated  distributions in excess of net investment  income by $76,782 and to
decrease   accumulated   distributions   in  excess  of  net  realized  gain  on
investments,  swap contracts, and foreign currency transactions by $977,104 with
an offsetting adjustment to paid-in capital.

      Distributions  to  shareholders  of the Fund's  6.00%  Series B Cumulative
Preferred   Stock  and  Series  C  Auction  Rate   Cumulative   Preferred  Stock
("Cumulative  Preferred Stock") are recorded on a daily basis and are determined
as described in Note 5.

             THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

      The tax  character  of  distributions  paid  during the fiscal  year ended
December 31, 2005 was as follows:

                                                     COMMON         PREFERRED
                                                   ----------      ----------
   DISTRIBUTIONS PAID FROM:

   Net long-term capital gains ..............       1,869,629         454,906
   Non-taxable return of capital ............       3,133,698              --

   Total distributions paid .................      $9,462,657      $2,302,395
                                                   ==========      ==========

      During 2005,  distributions  were made from  current  earnings and profits
that were in excess of required  distributions  and treated as ordinary  income.
The Fund utilized its capital loss carryforward of $900,322.

      PROVISION FOR INCOME  TAXES.  The Fund intends to continue to qualify as a
regulated  investment company under Subchapter M of the Internal Revenue Code of
1986, as amended (the  "Code").  It is the policy of the Fund to comply with the
requirements  of the Code  applicable to regulated  investment  companies and to
distribute  substantially  all of its net investment  company taxable income and
net capital gains. Therefore, no provision for Federal income taxes is required.

      As of December 31, 2005, the  components of accumulated  earnings/(losses)
on a tax basis were as follows:

         Net unrealized appreciation on investments .....   $ 2,064,941
         Other* .........................................       (33,294)
                                                            -----------
         Total ..........................................   $ 2,031,647
                                                            ===========

--------------
*     Other is primarily due to dividends payable.

      Differences  between amounts reported on a tax basis and those reported on
a book basis are  primarily  due to timing of  recognition  of capital  gains on
investments held by the Fund.

      The  following  summarizes  the tax cost of  investments  and the  related
unrealized appreciation/depreciation at June 30, 2006:

3. AGREEMENTS AND  TRANSACTIONS  WITH  AFFILIATES.  The Fund has entered into an
investment advisory agreement (the "Advisory  Agreement") with the Adviser which
provides  that the Fund  will pay the  Adviser  a fee,  computed  daily and paid
monthly,  equal on an annual  basis to 1.00% of the value of the Fund's  average
weekly net  assets  including  the  liquidation  value of  preferred  stock.  In
accordance  with the  Advisory  Agreement,  the  Adviser  provides a  continuous
investment  program for the Fund's portfolio and oversees the  administration of
all aspects of the Fund's business and affairs. The Adviser has agreed to reduce
the  management fee on the  incremental  assets  attributable  to the Cumulative
Preferred Stock if the total return of the NAV of the common shares of the Fund,
including  distributions and advisory fee subject to reduction,  does not exceed
the stated dividend rate or corresponding swap rate of each particular series of
the Cumulative Preferred Stock for the fiscal year.

      The Fund's total return on the NAV of the common  shares is monitored on a
monthly basis to assess whether the total return on the NAV of the common shares
exceeds the stated dividend rate or  corresponding  swap rate of each particular
series of Cumulative  Preferred  Stock for the period.  For the six months ended
June 30, 2006,  the Fund's total return on the NAV of the common  shares did not
exceed the stated dividend rate or net swap expense of all outstanding preferred
stock.  Thus,  management  fees with respect to the  liquidation  value of those
preferred stock assets were reduced by $246,805.

             THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

      During  the six  months  ended  June 30,  2006,  the Fund  paid  brokerage
commissions  of $21,510 to Gabelli & Company,  Inc.  ("Gabelli &  Company"),  an
affiliate of the Adviser.

      The  cost of  calculating  the  Fund's  NAV per  share  is a Fund  expense
pursuant to the Advisory Agreement between the Fund and the Adviser.  During the
six months ended June 30, 2006, the Fund paid or accrued  $22,500 to the Adviser
in connection  with the cost of computing  the Fund's NAV,  which is included in
miscellaneous expenses in the Statement of Operations.

      The Fund is  assuming  its  portion of the  allocated  cost of the Gabelli
Funds' Chief Compliance Officer in the amount of $2,042 for the six months ended
June 30,  2006,  which is  included  in payroll  expenses  in the  Statement  of
Operations.

discount  of 10% or more (or such other  percentage  as the Board may  determine
from time to time) from the NAV of the shares.  During the six months ended June

      The Fund's  Articles  of  Incorporation  authorize  the  issuance of up to
2,000,000 shares of $0.001 par value Cumulative  Preferred Stock. The Cumulative
Preferred  Stock is senior to the  common  stock and  results  in the  financial
leveraging of the common stock.  Such leveraging tends to magnify both the risks
and opportunities to common shareholders.  Dividends on shares of the Cumulative
Preferred Stock are cumulative.  The Fund is required by the 1940 Act and by the
Articles  Supplementary to meet certain asset coverage tests with respect to the
Cumulative  Preferred  Stock. If the Fund fails to meet these  requirements  and
does not correct such failure, the Fund may be required to redeem, in part or in
full, the 6% Series B and Series C Auction Rate  Cumulative  Preferred  Stock at
redemption prices of $25.00 and $25,000,  respectively, per share plus an amount
equal to the  accumulated and unpaid  dividends  whether or not declared on such
shares in order to meet these  requirements.  Additionally,  failure to meet the
foregoing asset coverage  requirements  could restrict the Fund's ability to pay
dividends to common shareholders and could lead to sales of portfolio securities
at  inopportune  times.  The income  received on the Fund's assets may vary in a
manner  unrelated  to the fixed and  variable  rates,  which could have either a
beneficial or detrimental impact on net investment income and gains available to
common shareholders.

      On March 18, 2003,  the Fund received net proceeds of  $23,994,241  (after
underwriting  discounts of $787,500 and offering  expenses of $218,259) from the
public  offering of  1,000,000  shares of 6.00%  Series B  Cumulative  Preferred
Stock.  Commencing March 19, 2008 and thereafter,  the Fund, at its option,  may
redeem the 6.00% Series B Cumulative  Preferred Stock in whole or in part at the
redemption  price at any time.  The Board has  authorized  the repurchase on the
open  market at prices  less than the $25  liquidation  value of the  Cumulative
Preferred  Stock.  During the six months ended June 30,  2006,  the Fund did not
repurchase  any shares of 6% Series B Cumulative  Preferred  Stock.  At June 30,
2006, 990,800 shares of 6% Series B Cumulative  Preferred Stock were outstanding
and accrued dividends amounted to $28,898.

             THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
              NOTES TO FINANCIAL STATEMENTS (CONTINUED) (UNAUDITED)

      On March 18, 2003,  the Fund received net proceeds of  $24,531,741  (after
underwriting  discounts of $250,000 and offering  expenses of $218,259) from the
public  offering of 1,000 shares of Series C Auction Rate  Cumulative  Preferred
Stock. The dividend rate, as set by the auction process, which is generally held
every 7 days, is expected to vary with short-term  interest rates.  The dividend
rates of Series C Auction Rate  Cumulative  Preferred Stock ranged from 4.15% to
5.16% for the six months ended June 30, 2006.  Existing  shareholders may submit
an order to hold,  bid,  or sell such  shares  on each  auction  date.  Series C
Auction Rate Cumulative  Preferred Stock  shareholders  may also trade shares in
the secondary market.  The Fund, at its option,  may redeem the Series C Auction
Rate Cumulative  Preferred Stock in whole or in part at the redemption  price at
any time. During the six months ended June 30, 2006, the Fund did not redeem any
shares of Series C Auction Rate  Cumulative  Preferred  Stock. At June 30, 2006,
1,000  shares  of  Series  C  Auction  Rate  Cumulative   Preferred  Stock  were
outstanding  with an  annualized  dividend  rate of 5.16% per share and  accrued
dividends amounted to $17,917.

      The holders of Cumulative  Preferred  Stock  generally are entitled to one
vote per share held on each matter  submitted to a vote of  shareholders  of the
Fund and will vote together with holders of common stock as a single class.  The
holders of  Cumulative  Preferred  Stock voting  together as a single class also
have the right currently to elect two Directors and under certain  circumstances
are entitled to elect a majority of the Board of  Directors.  In  addition,  the
affirmative  vote of a majority  of the votes  entitled to be cast by holders of
all outstanding shares of the preferred stock, voting as a single class, will be
required to approve any plan of reorganization adversely affecting the preferred
stock, and the approval of two-thirds of each class,  voting separately,  of the
Fund's  outstanding  voting stock must approve the conversion of the Fund from a
closed-end  to an open-end  investment  company.  The approval of a majority (as
defined in the 1940 Act) of the  outstanding  preferred stock and a majority (as
defined  in the  1940  Act) of the  Fund's  outstanding  voting  securities  are
required  to approve  certain  other  actions,  including  changes in the Fund's
investment objectives or fundamental investment policies.

6.  INDEMNIFICATIONS.  The Fund enters into  contracts that contain a variety of
indemnifications.  The Fund's  maximum  exposure  under  these  arrangements  is
unknown.  However, the Fund has not had prior claims or losses pursuant to these
contracts and expects the risk of loss to be remote.

7. OTHER MATTERS. The Adviser and/or affiliates have received subpoenas from the
Attorney General of the State of New York and the SEC requesting  information on
mutual fund trading  practices  involving  certain funds managed by the Adviser.
GAMCO Investors,  Inc. ("GAMCO"), the Adviser's parent company, is responding to
these  requests  for  documents  and  testimony.   In  June  2006,  GAMCO  began
discussions with the SEC regarding a possible resolution of their inquiry. Since
these discussions are ongoing, it cannot be determined at this time whether they
will ultimately  result in a settlement of this matter. On a separate matter, in
September  2005, the Adviser was informed by the staff of the SEC that the staff
may recommend to the  Commission  that an  administrative  remedy and a monetary
penalty be sought  from the  Adviser in  connection  with the  actions of two of
seven closed-end funds managed by the Adviser relating to Section 19(a) and Rule
19a-1 of the 1940 Act. These provisions require registered  investment companies
to provide  written  statements to  shareholders  when a dividend is made from a
source other than net investment  income.  While the two  closed-end  funds sent
annual statements and provided other materials containing this information,  the
funds did not send written  statements to shareholders with each distribution in
2002 and 2003. The Adviser believes that all of the funds are now in compliance.
The Adviser  believes that these matters would have no effect on the Fund or any
material adverse effect on the Adviser or its ability to manage the Fund.

             THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.

 BOARD CONSIDERATION AND RE-APPROVAL OF INVESTMENT ADVISORY CONTRACT (UNAUDITED)

At its meeting on May 17,  2006,  the Board of  Directors  ("Board") of the Fund
approved the continuation of the investment  advisory  contract with the Adviser
for the Fund on the basis of the  recommendation  by the  directors  who are not
"interested  persons"  of  the  Fund  (the  "independent  board  members").  The
following  paragraphs  summarize the material information and factors considered
by the independent board members as well as their  conclusions  relative to such
factors.

NATURE, EXTENT AND QUALITY OF SERVICES. The independent board members considered
information  regarding  the  portfolio  manager,  the depth of the analyst  pool
available to the Adviser and the portfolio  manager,  the scope of  supervisory,
administrative,  shareholder  and other  services  supervised or provided by the
Adviser,  and the absence of significant service problems reported to the Board.
The  independent  board members  noted the  experience,  length of service,  and
reputation of the portfolio manager.

INVESTMENT  PERFORMANCE.  The  independent  board  members  reviewed  the short,
medium,  and long-term  performance of the Fund since  inception  against a peer
group of convertible  securities and income/preferred stock closed-end funds and
the customized  peer group  selected by Lipper.  The  independent  board members
noted that the Fund's  comparative  performance  was fair to excellent  over the
short (one year) and longer  (five year)  periods,  depending  on the peer group
selected,  and was poor over the  intermediate  (three year) and long (ten year)
periods,  although understandable in relation to the conservative position taken
by the Fund.

PROFITABILITY. The independent board members reviewed summary data regarding the
profitability  of the Fund to the  Adviser  and  found the  profitability  to be
moderate.

ECONOMIES OF SCALE. The independent  board members  discussed the major elements
of the  Adviser's  cost  structure  and the  relationship  of those  elements to
potential  economies of scale. The independent board members noted that the Fund
was a closed-end fund and unlikely to realize any economies of scale potentially
available through growth.

SHARING OF ECONOMIES OF SCALE.  The  independent  board  members  noted that the
investment  advisory  fee  schedule  for the Fund does not take into account any
potential economies of scale.

SERVICE AND COST COMPARISONS. The independent board members compared the expense
ratios of the investment advisory fee, other expenses, and total expenses of the
Fund  to  similar   expense  ratios  of  the  peer  group  of  convertible   and
income/preferred  stock closed-end  funds as well as the customized  Lipper peer
groups and noted that the advisory fee includes substantially all administrative
services of the Fund as well as investment advisory services of the Adviser. The
independent  board  members  noted that the  Fund's  expense  ratios  were above
average  and the  Fund's  size  was  below  average  within  these  groups.  The
independent  board  members  were  presented  with,  but did not  consider to be
material to their decision,  various  information  comparing the advisory fee to
the fee for other types of accounts managed by affiliates of the Adviser.

CONCLUSIONS.  The  independent  board  members  concluded  that the Fund enjoyed
highly experienced portfolio management services, good ancillary services, and a
reasonable  performance  record within its conservative  stance. The independent
board members also concluded  that the Fund's expense ratios were  reasonable in
light of the Fund's  size,  and that,  in part due to the Fund's  structure as a
closed-end  fund,  economies  of scale  were not a  significant  factor in their
thinking. The independent board members did not view the potential profitability
of  ancillary  services  as  material  to their  decision.  On the  basis of the
foregoing and without assigning particular weight to any single conclusion,  the
independent board members determined to recommend continuation of the investment
advisory contract to the full Board.

                         AUTOMATIC DIVIDEND REINVESTMENT
                        AND VOLUNTARY CASH PURCHASE PLAN

ENROLLMENT IN THE PLAN

      It is the policy of The Gabelli  Convertible  and Income  Securities  Fund
Inc.  (the  "Fund")  to  automatically  reinvest  dividends.  As a  "registered"
shareholder  you  automatically  become a  participant  in the Fund's  Automatic
Dividend  Reinvestment Plan (the "Plan").  The Plan authorizes the Fund to issue
shares of common  stock to  participants  upon an income  dividend  or a capital
gains distribution regardless of whether the shares are trading at a discount or
a premium to net asset value. All distributions to shareholders whose shares are
registered in their own names will be automatically  reinvested  pursuant to the
Plan in additional  shares of the Fund. Plan  participants  may send their stock
certificates to Computershare Trust Company,  N.A.  ("Computershare") to be held
in their  dividend  reinvestment  account.  Registered  shareholders  wishing to
receive their distribution in cash must submit this request in writing to:

             The Gabelli Convertible and Income Securities Fund Inc.
                               c/o Computershare
                                 P.O. Box 43010
                           Providence, RI 02940-3010

      Shareholders  requesting this cash election must include the shareholder's
name and  address as they  appear on the share  certificate.  Shareholders  with
additional  questions  regarding  the Plan, or requesting a copy of the terms of
the plan may contact Computershare at (800) 336-6983.

      If your shares are held in the name of a broker,  bank,  or  nominee,  you
should contact such institution. If such institution is not participating in the
Plan,  your  account  will  be  credited  with  a cash  dividend.  In  order  to
participate in the Plan through such institution, it may be necessary for you to
have your shares taken out of "street name" and  re-registered in your own name.
Once  registered  in  your  own  name  your  dividends  will  be   automatically
reinvested. Certain brokers participate in the Plan. Shareholders holding shares
in "street name" at participating institutions will have dividends automatically
reinvested.  Shareholders  wishing  a cash  dividend  at such  institution  must
contact their broker to make this change.

      The number of shares of common stock  distributed to  participants  in the
Plan in lieu of cash dividends is determined in the following manner.  Under the
Plan,  whenever  the  market  price of the  Fund's  common  stock is equal to or
exceeds  net  asset  value  at the  time  shares  are  valued  for  purposes  of
determining  the number of shares  equivalent  to the cash  dividends or capital
gains distribution, participants are issued shares of common stock valued at the
greater of (i) the net asset value as most  recently  determined  or (ii) 95% of
the then current market price of the Fund's common stock.  The valuation date is
the  dividend or  distribution  payment  date or, if that date is not a New York
Stock  Exchange  ("NYSE")  trading  day,  the next trading day. If the net asset
value of the common stock at the time of  valuation  exceeds the market price of
the common  stock,  participants  will  receive  shares  from the Fund valued at
market  price.   If  the  Fund  should  declare  a  dividend  or  capital  gains
distribution  payable only in cash,  Computershare  will buy common stock in the
open market, or on the NYSE or elsewhere, for the participants' accounts, except
that Computershare  will endeavor to terminate  purchases in the open market and
cause the Fund to issue shares at net asset value if, following the commencement
of such purchases, the market value of the common stock exceeds the then current
net asset value.

      The automatic  reinvestment  of dividends and capital gains  distributions
will not  relieve  participants  of any  income tax which may be payable on such
distributions.  A participant in the Plan will be treated for Federal income tax
purposes  as  having  received,  on a  dividend  payment  date,  a  dividend  or
distribution in an amount equal to the cash the participant  could have received
instead of shares.


                                       19


      Fund  reserves the right to amend or terminate  the Plan as applied to any
voluntary cash payments made and any dividend or distribution paid subsequent to
written  notice of the change  sent to the  members of the Plan at least 90 days
before the record date for such dividend or  distribution.  The Plan also may be
amended or terminated by  Computershare  on at least 90 days' written  notice to
participants in the Plan.

VOLUNTARY CASH PURCHASE PLAN

      The  Voluntary  Cash  Purchase  Plan  is  yet  another   vehicle  for  our
shareholders  to increase their  investment in the Fund. In order to participate
in the  Voluntary  Cash  Purchase  Plan,  shareholders  must have  their  shares
registered in their own name.

      Participants in the Voluntary Cash Purchase Plan have the option of making
additional cash payments to  Computershare  for investments in the Fund's shares
at the then current market price.  Shareholders  may send an amount from $250 to
$10,000.  Computershare  will use  these  funds to  purchase  shares in the open
market on or about the 1st and 15th of each  month.  Computershare  will  charge
each shareholder who participates  $0.75, plus a pro rata share of the brokerage
commissions.  Brokerage  charges for such purchases are expected to be less than
the usual  brokerage  charge for such  transactions.  It is  suggested  that any
voluntary cash payments be sent to Computershare, P.O. Box 43010, Providence, RI
02940-3010 such that Computershare  receives such payments approximately 10 days
before  the 1st and 15th of the  month.  Funds not  received  at least five days
before the investment date shall be held for investment  until the next purchase
date.  A payment  may be  withdrawn  without  charge if  notice is  received  by
Computershare at least 48 hours before such payment is to be invested.

      SHAREHOLDERS  WISHING TO LIQUIDATE SHARES HELD AT COMPUTERSHARE must do so
in writing or by telephone.  Please  submit your request to the above  mentioned
address or telephone  number.  Include in your  request  your name,  address and
account number. The cost to liquidate shares is $2.50 per transaction as well as
the brokerage  commission  incurred.  Brokerage  charges are expected to be less
than the usual brokerage charge for such transactions.

      For  more  information   regarding  the  Dividend  Reinvestment  Plan  and
Voluntary Cash Purchase Plan,  brochures are available by calling (914) 921-5070
or by writing directly to the Fund.

      The Fund  reserves the right to amend or terminate the Plans as applied to
any  voluntary  cash  payments  made  and  any  dividend  or  distribution  paid
subsequent  to written  notice of the change  sent to the members of the Plan at
least 90 days before the record date for such dividend or distribution. The Plan
also may be amended or terminated by  Computershare on at least 90 days' written
notice to participants in the Plan.
