INVESTMENT OBJECTIVE:

The Gabelli Convertible Securities Fund, Inc. (the "Fund") is a closed-end,
diversified management investment company whose primary objective is to seek a
high level of total return through a combination of current income and capital
appreciation by investing in convertible securities.

                    THIS REPORT IS PRINTED ON RECYCLED PAPER.



TO OUR SHAREHOLDERS,

      As  hybrid  securities  with  equity  and  fixed  income  characteristics,
convertible security performance is impacted by stock and bond market trends. In
the first quarter of 2001, bonds rallied as equities declined in response to the
rapidly decelerating economy and widespread earnings shortfalls.  Three 50 basis
point Federal Funds rate cuts in the first quarter,  one again in April, and the
probability of further  Federal Reserve Board ("Fed") easing in the months ahead
failed to raise equity investors'  spirits,  but provided an additional tailwind
for bonds.  The high yields of the many "busted"  convertibles in our portfolio,
or convertibles  whose  underlying  equities were trading well below  conversion
parity,  helped the Fund post a solid gain and outperform  both leading bond and
stock market indices.

                                   FUND, INC.

INVESTMENT PERFORMANCE

      For the first  quarter  ended March 31,  2001,  the Fund's net asset value
("NAV") total return was up 3.40% after  adjusting for the  reinvestment  of the
$0.20 per share  distribution  paid on March 26,  2001.  The  Standard  & Poor's
("S&P") 500 Index and the Lipper  Convertible  Securities Fund Average  declined
11.85% and 8.53%,  respectively,  over the same period.  The S&P 500 Index is an
unmanaged  indicator  of stock  market  performance,  while the  Lipper  Average
reflects the average  performance of mutual funds  classified in this particular
category.  The Fund rose  2.06%  over the  trailing  twelve-month  period  after
adjusting  for the  reinvestment  of the $1.30 per share in  distributions  paid
during this period.  The S&P 500 Index and Lipper  Convertible  Securities  Fund
Average  declined 21.67% and 15.31%,  respectively,  over the same  twelve-month
period.

      For the  two-year  period  ended March 31,  2001,  the Fund's total return
averaged  5.42%  annually,   including  reinvestments  of  $2.33  per  share  in
distributions.  The S&P 500 Index  declined  3.88%  annually,  while the  Lipper
Convertible  Securities  Fund Average rose 9.07% annually over the same two-year
period.  For the five-year  period ended March 31, 2001, the Fund's total return
averaged  7.78%  annually,  including  reinvestments  of  $5.025  per  share  in
distributions,  versus average annual total returns of 14.18% and 10.32% for the
S&P 500 Index and Lipper Convertible Securities Fund Average, respectively.

      Since  inception  on July 3, 1989 through  March 31, 2001,  the Fund had a
cumulative total return of 180.67%,  including  adjustments of $11.166 per share
for distributions, which equates to an average annual total return of 9.18%.

      The Fund's  common  shares ended the first  quarter at $10.20 per share on
the New York Stock  Exchange,  a premium  to the net asset  value of 0.39% and a
total  return of 13.99% for the first  quarter.  The Fund's  common  shares rose
20.51%  over  the  trailing   twelve-month   period  after   adjusting  for  all
distributions.

CORPORATE GOVERNANCE - GCV TRADING AT A PREMIUM!

      In past reports we have outlined several  management  initiatives that the
Board of  Directors  has taken to increase the Fund's  public  market price to a
level  equal to or  exceeding  the Fund's  net asset  value.  These  initiatives
included a stock  repurchase  plan, a managed 8%  Distribution  Policy,  and the
issuance of preferred stock. Additionally, when the Fund converted to closed-end
status in March 1995,  we expressed  our intent to have the Fund's common shares
track the Fund's net asset value.



      We are  happy to report to you that the  public  market  price is now at a
premium to the net asset  value.  As of the writing of this  shareholder  letter
(May 8, 2001), the Fund's shares were trading at a premium of 1.5% to the Fund's
net asset value. This is a testament to our pro-active  shareholder  initiatives
and the consistency of our performance over time.

OUR OBJECTIVE

      Our mandate is to preserve and enhance our shareholders'  wealth through a
conservative and disciplined approach to convertible  securities investing.  Our
goal is to generate  profitable  returns in strong markets and protect principal
in weak markets by taking advantage of the unique characteristics of convertible
securities.

      Our Fund is managed with a goal of achieving a 600-800  basis point spread
above  long-term  Treasury  yields.  We hope to generate  these returns over the
long-term. This is the type of performance that our Fund has been recognized for
and we  anticipate  will  continue  in  the  future.  Of  course,  there  are no
guarantees.

WHAT WE DO

      The success of momentum  investing in recent years and  investors'  desire
for instant  gratification have combined to make value investing appear dull. At
the risk of being dull, we will once again  describe the "boring" value approach
that has seen us through both good and bad markets over the last 11 years at the
Fund and for over 24 years at Gabelli Asset Management Company. In past reports,
we have tried to articulate  our  investment  philosophy  and  methodology.  The
following graphic further illustrates the interplay among the four components of
our valuation approach.

                               [GRAPHICS OMITTED]

      Our  focus  is  on  free  cash  flow:  earnings  before  interest,  taxes,
depreciation  and  amortization   ("EBITDA")  minus  the  capital   expenditures
necessary to grow the business.  We believe free cash flow is the best barometer
of a business'  value.  Rising  free cash flow often  foreshadows  net  earnings
improvement.  We also look at earnings per share  trends.  Unlike Wall  Street's
ubiquitous  earnings momentum  players,  we do not try to forecast earnings with
accounting  precision and then trade stocks based on quarterly  expectations and
realities.  We simply try to position  ourselves in front of long-term  earnings
uptrends.  In  addition,  we  analyze  on  and  off  balance  sheet  assets  and
liabilities such as plant and equipment,  inventories,  receivables,  and legal,
environmental  and health care issues.  We want to know  everything and anything
that will add to or detract from our private market value ("PMV") estimates.

      Finally,  we look for a catalyst:  something  happening  in the  company's
industry or indigenous  to the company  itself that will surface  value.  In the
case of the independent  telephone stocks,  the catalyst is a regulatory change.
In the agricultural  equipment business,  it is the increasing world-wide demand
for  American  food and feed crops.  In other  instances,  it may be a change in
management,  sale or spin-off of a division or the  development  of a profitable
new business.

      Once we  identify  stocks  that  qualify  as  fundamental  and  conceptual
bargains,  we then become patient  investors.  This has been a proven  long-term
method for preserving and enhancing wealth in the U.S.  equities market.  At the
margin,  our new investments are focused on businesses that are well-managed and
will benefit from sustainable  long-term economic dynamics.  These include macro
trends,  such as the  globalization  of the market in filmed  entertainment  and
telecommunications, and micro trends, such as an increased focus on productivity
enhancing goods and services.

CONVERTIBLE SECURITIES ARE "HYBRIDS"

      It is important to understand our stock selection discipline because price
movement in the underlying  equity will  generally  have the greatest  impact on
convertible  securities pricing.  The convertible  securities market consists of
bonds,  debentures,  corporate  notes,  preferred  stocks and  warrants or other
similar securities which may be

                                        3



converted  into or exchanged  for a  prescribed  amount of common stock or other
equity security of the same or a different issuer within a particular  period of
time at a specified  price or formula.  Converts  are "hybrid"  securities  that
combine the capital appreciation  potential of equities with the higher yield of
fixed income instruments.  Our strategy incorporates the purchase of convertible
securities  that are trading at a premium above parity with the common stock but
which generally provide a higher yield and, over time, capital appreciation.  We
will also seek out  "busted"  converts,  where the  underlying  common stock has
dropped  significantly  and the values of both the conversion  privilege and the
convert are down.  Such  securities  will provide both high yields and long-term
capital appreciation potential.

CONVERTIBLE MARKET OVERVIEW

      The size of the U.S.  convertible  market  grew by $5  billion  during the
quarter to $159 billion.  This market now constitutes  38.1% of the $399 billion
global  convertible  market.  The U.S. is the largest  convertible market in the
world followed by Japan and Europe each with 27.2%.  Net new issuance  reached a
record high of $14 billion  during the quarter as falling  equity prices stymied
voluntary conversions.

      Zero-coupon  convertible  structures  continued to increase  their overall
share of the U.S.  convertible  market rising to 27.9% versus 22.6% at year-end.
Demand for these  issues has been  strong as  investors  seek  shelter  from the
current  market  volatility.  Zero-coupon  deals tend to be issued by investment
grade credits and are the most  bond-like  (i.e.  defensive) of all  convertible
structures because of their embedded put options. Via the put option,  investors
can return (i.e. put back) the  convertible  to the issuer at a designated  time
and price.  Contingent  conversion  and coupon  features have also increased the
attractiveness  of these  structures  for issuers who benefit from favorable tax
and accounting treatment.

      In terms of  performance,  convertibles  continued  to  demonstrate  their
defensive  qualities by falling only 6% during the quarter  versus 11.9% for the
S&P 500 and  8.0% for the Dow  Industrials.  The best  performing  sectors  were
Consumer  Discretionary,  which was up by 11.1%,  and  Materials,  which rose by
10.8%.  The  poorest   performing   sectors   continued  to  be  Technology  and
Telecommunications, which were down 13.3% and 9.5% respectively.

COMMENTARY

MONETARY  POLICY  + FISCAL  POLICY +  LEVELING  OF  ENERGY + ROUND OF  INVENTORY
CORRECTIONS = CONSUMER LEAD ECONOMIC RECOVERY AND EARNINGS GAINS IN 2002

      Federal  Reserve Board ("Fed")  Chairman Alan Greenspan was a superhero to
Wall Street through a decade-long economic expansion and bull market.  Suddenly,
he is on the verge of becoming public enemy number one,  raising  interest rates
too aggressively when the economy and stock market were roaring,  and failing to
reverse course fast enough as the economy flagged and the stock market went into
a tailspin.  In reality, Mr. Greenspan has always been a mere mortal, and a very
smart guy who has done a good job tuning  monetary policy to the natural rhythms
of the business cycle.

      It took a series of six  Federal  Funds  rate hikes to put the brakes on a
runaway economy. The Fed has already cut rates three times in the first quarter,
once again in April,  and it will probably  continue  easing to help the economy
regain momentum.  Fed rate cuts will eventually put the economy back on a growth
path, albeit not as rapidly as Wall

                                        4



Street might like. While the stock market decline has been painful for everyone,
much if not all the  excesses  in the market have been  eliminated,  providing a
much more solid foundation to build upon.

YES VIRGINIA, THERE IS A BUSINESS CYCLE

      Where are we today?  Where  are we headed  tomorrow?  Most of us with gray
hair (or no hair) have been  around long enough to  recognize  an  old-fashioned
inventory  correction when we see one. During the good times,  businesses expand
capacity and production to meet rising demand. When demand slackens,  production
must be cut. The pipeline has to be brought  into  balance.  Corporate  earnings
suffer  until  demand  firms and  excess  inventories  are worked  off.  This is
Economics  101.  The  only  difference  in  this  otherwise   classic  inventory
correction  is that it  developed  much  quicker  than most  expected and had an
exaggerated impact on a grossly overvalued stock market.

AND THE QUESTION IS ...

      Let us revisit what we articulated in our Gabelli Equity Trust 2000 annual
report.  "OVER THE NEXT SEVERAL  MONTHS,  THE OVERALL MARKET NEEDS TO UNDERSTAND
WHETHER  MONETARY  POLICY  (GREENSPAN'S  RATE CUTS)  MARRIED WITH FISCAL  POLICY
(BUSH'S TAX CUTS) WILL PROVIDE THE BALLAST TO OVERCOME THE ECONOMIC DRAG CREATED
BY: A  CONSUMER  SPENDING  BINGE  (TIED TO THE STOCK  MARKET'S  WEALTH  EFFECT);
OVERSPENDING ON CAPITAL EQUIPMENT; AND A TRADE DEFICIT OF GIGANTIC PROPORTIONS."

      In our opinion,  this inventory  correction will also end faster than most
folks are  anticipating.  Demand  appears to be  flattening  out, and with lower
variable rate  mortgage  payments,  adjustments  to higher  gasoline  prices and
higher home  heating/cooling  costs (but not for  California  residents  where a
catch-up  is in  process),  and some extra  money in  paychecks  coupled  with a
renewed  belief  that things will get better  from lower  federal  income  taxes
headed our way this summer, demand should begin recovering. It may take time for
inventories  to get worked off, and past  over-investment  in capital  equipment
will  dampen the  recovery.  Yet, we believe  corporate  earnings  should  begin
rebounding in the first quarter of 2002.

THE ALPHABET DEBATE

      Gone are the days of  "irrational  exuberance",  cautioned by Fed Chairman
Alan Greenspan in December 1996. Now that the global  economic  slowdown is upon
us, the debate has shifted to when and how quickly the recovery will occur. Will
it be "V",  "U", or "L"  shaped?  We do not know?  However,  we do know that Mr.
Market  remains  focused on  short-term  disappointments  rather than  long-term
fundamentals.  This provides us with attractive investment opportunities. A case
in point would be Sealed Air Corporation  (SEE);  the New Jersey based packaging
company. The share price had been cut in half due to concerns over the effect of
higher oil prices on operating margins and the consequences of "mad cow" disease
on European  sales (i.e.  only 1% of total  sales).  With the stock at $30,  our
estimate of intrinsic  value was over $60 per share.  The company's  convertible
preferred stock, on a 6.15% current yield and 22% conversion premium, offered an
attractive  investment  vehicle by which to be "paid to wait" for a catalyst  to
unlock this value. We were not alone in our assessment of SEE's hidden value. On
Valentine's Day, Warren Buffett revealed that he had acquired over a 5% stake in
SEE. This proved to be the catalyst  that  catapulted  the stock price,  and the
convertible, up over 13%.

INVESTMENT SCORECARD

      The  strong   performance  of   broadcasting   company   convert   Granite
Broadcasting,  broadcaster/publisher  Tribune/Times  Mirror,  drug retailer Rite
Aid, services conglomerate  Cendant, and auto-parts  manufacturers WHX Corp. and
Standard Motor Products contributed to returns.

      Returns from our utility  companies were mixed,  with KCS Energy among our
best   performers  and  Northeast   Utilities   among  our  worst.  In  general,
telecommunications companies performed poorly during the first quarter.

      The  critical  element  to our  success  in  the  equity  and  convertible
securities  markets  has been  patience  in both the  selection  process  and in
waiting for the values of portfolio positions to be recognized. We will continue
to be patient and  opportunistic  in  selecting  converts  for the Fund and will
invest in  short-term  instruments  (including  time  sensitive  workouts)  when
appropriate.  We purchased mostly  short-term U.S.  Treasury  obligations in the
past. However,  the U.S. financial system has improved  significantly and we now
take advantage of other  short-term  alternatives.  In this regard,  the Fund at
times engages in risk arbitrage to generate  returns.  By risk arbitrage we mean
investing in "event"  driven  situations;  primarily,  but not  exclusively,  in
announced   mergers,   acquisitions,   reorganizations   and   other   "workout"
opportunities. In order to avoid overall market risk in these opportunities, the
Fund will concentrate on lower risk transactions.

      Simply  stated,  risk  arbitrage is  investing in a merger or  acquisition
target after the deal has been  announced and  pocketing the spread  between the
trading  price of the target  company  following the  announcement  and the deal
price  upon  closing.  This  spread is  usually  relatively  narrow,  offering a
somewhat  modest nominal total return.  However,  since deals generally close in
much less than a year's time,  this modest total return  translates  into a much
more attractive annualized return.

      We borrow a quote from  Warren  Buffett to explain our  occasional  use of
risk arbitrage in the Fund: "Our  subsidiaries  sometimes engage in arbitrage as
an alternative to holding short-term cash equivalents.  We prefer, of course, to
make major long-term  commitments.  But we often have more cash than good ideas.
At such times  arbitrage  sometimes  promises much greater returns than Treasury
Bills and,  equally  important,  cools any  temptation  we may have to relax our
standards for long-term investments."

      In short,  the high cash  position in the Fund does not reflect any effort
on  our  part  to  time  the  convertible  securities  market.  It is  rather  a
consequence of our  value-oriented  discipline.  At the same time, a sampling of
our  convertible  securities  has been  called  by their  issuers  and we either
received cash or stock. Our portfolio  turnover rate reflects this activity,  as
well as our  investments  in "event"  driven  situations  that were  consummated
during  the  year.  We are  always  hard at work  evaluating  opportunities  and
identifying  fundamental  bargains to progress to a more fully invested posture.
However,  we will not stretch our fundamental  parameters and introduce  greater
market risk to the portfolio.

LET'S TALK CONVERTS

      The following are  specifics on selected  holdings of our Fund.  Favorable
earnings prospects do not necessarily  translate into higher prices, but they do
express a positive trend which we believe will develop over time.

CITIZENS  COMMUNICATIONS  CO.  (5.00% CV.  PFD.) will soon become the  country's
largest  independent  local  exchange  carrier with about 3 million access lines
once it completes several acquisitions of over 2 million lines for $6.5 billion.
Upon  completion  of these  transactions,  accompanied  by  divestitures  of its
utilities   operations,   the  company   will   reposition   itself  as  a  pure
telecommunications  company.  Citizens also owns 81% of a  competitive  carrier,
Electric Lightwave (ELIX - $3.3125 - Nasdaq), with fiber optic networks covering
the Western part of the U.S.

HILTON HOTELS CORP. (HLT) (SUB. DEB. CV., 5.00%,  05/15/06) is recognized as one
of the world's preeminent hospitality companies.  Hilton develops, owns, manages
and franchises hotels,  resorts and vacation ownership properties.  Based on the
number of hotel rooms,  Hilton is the nation's  seventh  largest hotel  company.
Hilton has  approximately 260 hotels and resorts in cities throughout the United
States,  including 54 owned and/or managed hotels and 199 hotels under franchise
agreements. Flagship properties include The Waldorf-Astoria,  the Hilton Chicago
& Towers,  Hilton  Hawaiian  Village  (98%-owned)  and Palmer House Hilton.  HLT
formalized  a marketing  alliance  with British  company  Hilton Group plc (HG -
$12.14 - London Stock Exchange) (owner of Hilton  International) in January 1997
to  reunite  the  Hilton  name  worldwide  for the first  time in over 30 years.
Hilton's casino gaming  properties  have been spun-off into a new company,  Park
Place Entertainment (PPE - $10.25 - NYSE).

KAMAN CORP. (SUB. DEB. CV., 6.00%,  03/15/12),  founded in 1945, is a pioneer in
the  helicopter  industry.  Aircraft  manufacturing  remains  the  core  of  the
business. Kaman serves both commercial and governmental markets with helicopters
and aircraft components. The company also produces specialized, high-value niche
market  products and  services  that tend to be  technological  leaders in their
markets.  Kaman is a major,  national distributor of original equipment,  repair
and  replacement  products  and  value-added  services to nearly every sector of
North American industry.  The company also manufactures and distributes  musical
instruments (Ovation guitars) and accessories to independent retailers.

ROBBINS & MYERS INC.  (SUB.  DEB.  CV.,  6.50%,  09/01/03)  is an  international
manufacturer of industrial mixing  equipment,  glass-lined  vessels,  industrial
pumps and corrosion  resistant  products serving the process industries such as:
specialty chemicals, pharmaceuticals, water treatment, oil and gas, and food and
beverage.  The Energy Systems  business,  with a $12 million  backlog along with
higher  sustained  crude oil and  natural  gas  prices  and  increased  drilling
activity, should remain strong through the balance of fiscal 2001. We think that
revenues in the Process  Systems segment will be down in 2001 due to weakness in
end  markets,  but with a backlog of almost  $86  million,  the  segment is well
positioned for the future. The company will continue to use its strong cash flow
to make acquisitions and develop new products enhancing its growth prospects.

SEALED AIR CORP.  ($2.00 CV. PFD., SER. A), located in Saddle Brook, New Jersey,
manufactures and sells packaging products to customers worldwide.  The company's
share  price  nearly  halved last year  because of  concerns  over the effect of
higher  oil  prices on  operating  margins  and fears of "Mad  Cow"  disease  on
European  sales  (only 1% of total  sales).  With the stock  price below $30, we
believed the company's intrinsic value to be over $60. We were not alone

                                        7



in identifying this hidden value. On February 14, 2001, Warren Buffett presented
us with an  unexpected  Valentine's  Day present by  disclosing  that  Berkshire
Hathaway had acquired a 5.7% stake in Sealed Air. This proved to be the catalyst
that drove the stock price, and the convertible, up over 13% during the quarter.

SEQUA  CORP.  ($5.00 CV.  PFD.) is a  diversified  company  with  businesses  in
aerospace,   pre-paint  metal,  specialty  chemical  and  printing  and  cannery
equipment.  Chromalloy Gas Turbine,  Sequa's aerospace business,  is the largest
independent  supplier of overhaul and repair to jet and  industrial  gas turbine
engines.  We believe this business is attractive  to original  equipment  engine
manufacturers  like General Electric and Pratt & Whitney who are looking to grow
their  replacement  parts  business.  With roughly $800 million in revenues,  we
estimate Chromalloy's private market value to be near the entire public value of
Sequa.

STANDARD  MOTOR  PRODUCTS  INC.  (SMP)  (SUB.   DEB.  CV.,   6.75%,   07/15/09),
headquartered  in Long Island City, New York,  supplies  functional  replacement
parts for the engine management, electrical and climate control systems of cars,
trucks and buses.  The company  services all makes and models,  both new and old
cars, imported and domestic.  SMP has two primary  divisions--engine  management
and temperature control--and believes it is the number one supplier to the North
American aftermarket in each of these lines.

WASTE MANAGEMENT INC. (SUB. DEB. CV., 4.00%,  02/01/02) merged with USA Waste in
1998, and is now the largest solid waste company in North  America.  The company
provides a number of services,  including collection,  transfer,  landfill,  and
recycling   services  for  a  diverse  customer  base,  notably  the  municipal,
residential,   commercial,   and  industrial  markets.   Services  are  provided
throughout  the United  States as well as in Canada,  Mexico,  and Puerto  Rico.
Internationally,  the company operates in Europe,  the Pacific Rim, and in South
America.  In addition,  Waste Management is a leading developer,  operator,  and
owner of waste-to-energy facilities in the U.S.

IN CONCLUSION

      High yields helped  support  convertible  securities  prices as underlying
common  stocks  declined  sharply in the first  quarter  of 2001.  The Fund also
benefited  from  the  strong  relative  performance  of  convertible  securities
investments in multimedia  companies and beaten down  manufacturers in a variety
of industries. Looking ahead, we believe yield will continue to provide downside
support in this volatile stock market environment.  If the stock market recovers
in  the  second  half,  the  equity-oriented   performance   characteristics  of
convertibles should make more of a contribution.

                                      Sincerely,

                                      /s/ MARIO J. GABELLI

                         AUTOMATIC DIVIDEND REINVESTMENT
                        AND VOLUNTARY CASH PURCHASE PLAN

ENROLLMENT IN THE PLAN
   It  is  the  Policy  of  The  Gabelli   Convertible   Securities  Fund,  Inc.
("Convertible  Securities  Fund")  to  automatically  reinvest  dividends.  As a
"registered"   shareholder  you  automatically   become  a  participant  in  the
Convertible Securities Fund's Automatic Dividend Reinvestment Plan (the "Plan").
The  Plan  authorizes  the  Convertible  Securities  Fund  to  issue  shares  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  Convertible  Securities  Fund.  Plan  participants  may  send  their  stock
certificates to State Street Bank and Trust Company ("State  Street") 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 Securities Fund, Inc.
                     c/o State Street Bank and Trust Company
                                  P.O. Box 8200
                              Boston, MA 02266-8200

   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 State Street at 1 (800) 336-6983.

   SHAREHOLDERS WISHING TO LIQUIDATE REINVESTED SHARES held at State Street Bank
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.  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 Convertible  Securities  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 Convertible Securities 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  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 Convertible
Securities  Fund valued at market  price.  If the  Convertible  Securities  Fund
should  declare a dividend or capital gains  distribution  payable only in cash,
State Street will buy Common Stock in the open market,  or on the New York Stock
Exchange or elsewhere, for the participants' accounts,  except that State Street
will  endeavor  to  terminate  purchases  in  the  open  market  and  cause  the
Convertible Securities 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.

   The Convertible  Securities 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 State Street 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  Convertible  Securities  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 State Street Bank and Trust Company for investments
in the  Convertible  Securities  Fund shares at the then current  market  price.
Shareholders  may send an amount  from $250 to  $10,000.  State  Street Bank and
Trust  Company will use these funds to purchase  shares in the open market on or
about the 1st and 15th of each month.  State Street Bank and Trust  Company 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 State Street Bank and Trust Company, P.O.
Box 8200,  Boston,  MA 02266-8200  such that State Street receives such payments
approximately  10 days before the investment  date.  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 State Street Bank and Trust  Company at least 48 hours before such payment is
