             THE GABELLI CONVERTIBLE AND INCOME SECURITIES FUND INC.
                  NOTES TO SCHEDULE OF INVESTMENTS (UNAUDITED)

1. 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 of Directors  (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.

ADOPTION OF  STATEMENT  OF FINANCIAL  ACCOUNTING  STANDARDS  NO. 157 "FAIR VALUE
MEASUREMENTS" ("SFAS 157")

On January 1, 2008,  the Fund adopted SFAS 157 that  clarifies the definition of
fair value for financial  reporting,  establishes a framework for measuring fair
value,  and  requires  additional  disclosures  about  the  use  of  fair  value
measurements.  The three levels of the fair value  hierarchy  under SFAS 157 are
described below:

      o     Level 1 - quoted prices in active markets for identical securities;

      o     Level 2 - other  significant  observable  inputs  (including  quoted
            prices for similar  securities,  interest rates,  prepayment speeds,
            credit risk, etc.); and

      o     Level 3 -  significant  unobservable  inputs  (including  the Fund's
            determinations as to the fair value of investments).

The inputs or methodology  used for valuing  securities  are not  necessarily an
indication  of the risk  associated  with  investing  in those  securities.  The
summary of inputs used to value the Fund's net assets as of March 31, 2008 is as
follows:

2. SWAP  AGREEMENTS.  The Fund may enter into equity and contract for difference
swap  transactions.  The use of  swaps  is a highly  specialized  activity  that
involves  investment  techniques and risks different from those  associated with
ordinary portfolio security transactions.  In a swap, a set of future cash flows
are exchanged  between two  counterparties.  One of these cash flow streams will
typically be based on a reference interest rate combined with the performance of
a  notional  value  of  shares  of a  stock.  The  other  will be  based  on the
performance  of the  shares  of a  stock.  There is no  assurance  that the swap
contract  counterparties will be able to meet their obligations  pursuant to the
swap  contracts,  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 the swap
contracts.  The creditworthiness of the swap contract  counterparties is closely
monitored  in order to minimize  the risk.  Depending  on the  general  state of
short-term interest rates and the returns of the Fund's portfolio  securities at
that point in time, such a default could negatively affect the Fund's ability to
make dividend payments.  In addition, at the time a swap 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.

The use of derivative  instruments may involve, to varying degrees,  elements of
market and counterparty risk in excess of the amount recognized below.

The Fund has entered into a contract for  difference  swap  agreement with Bear,
Stearns  International  Limited.  Details  of the swap at March  31,  2008 is as
follows:

                         AUTOMATIC DIVIDEND REINVESTMENT
                        AND VOLUNTARY CASH PURCHASE PLANS

ENROLLMENT IN THE PLAN

      It is the policy of The Gabelli  Convertible  and Income  Securities  Fund
Inc.  (the  "Fund")  to  automatically  reinvest  dividends  payable  to  common
shareholders.   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 credit 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 distributions 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.

                                        8



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 Automatic  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 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.
