                                  INTRODUCTION

   The Alger Fund's portfolios,  other than Alger Money Market Portfolio,  offer
three classes of shares having  different sales charges,  ongoing fees and other
features.  You may purchase the class of shares that is most  beneficial  to you
based  upon the  amount of the  purchase,  the length of time you expect to hold
shares and other circumstances.

Class A Shares

   An investor  purchasing  Class A Shares may pay a sales charge at the time of
purchase.  Class A Shares  are not  subject to a charge  when they are  redeemed
(except for shares  purchased  for total  proceeds of $1 million or more,  which
have no initial  sales charge and which may be subject to a contingent  deferred
sales charge  ["CDSC"]).  The initial  sales charge may be reduced or waived for
certain  purchases.  Class A Shares are subject to a  shareholder  servicing fee
equal to an annual  rate of .25% of the  Portfolio's  average  daily net  assets
attributable to its Class A Shares.  See "How to Purchase  Shares--Class A Share
Information."

Class B Shares

   Class B Shares are  offered  for sale for  purchases  of less than  $250,000.
Class B Shares have no initial sales charge,  but may be subject to a CDSC of up
to 5% if you  redeem  within  six  years  of  purchase.  They are  subject  to a
distribution  (Rule  12b-1)  fee at an  annual  rate of .75% of the  Portfolio's
average daily net assets attributable to Class B Shares. Class B Shares also pay
a  shareholder  servicing  fee  calculated  at an  annual  rate  of  .25% of the
Portfolio's average daily net assets attributable to its Class B Shares. Class B
Shares provide an investor the benefit of putting all of the investor's  dollars
to work  from the time the  investment  is made but will  have a higher  expense
ratio and  generally  will pay lower  dividends  than  Class A Shares due to the
distribution fee on Class B Shares. Class B Shares will automatically convert to
Class A Shares  eight  years  after the end of the  calendar  month in which the
investor's order to purchase was accepted.  See "How to Purchase Shares--Class B
Share Information."

Class C Shares

   Class C Shares are offered for sale for  purchases  of less than  $1,000,000.
There is no initial sales charge for Class C Shares,  but they may be subject to
a CDSC of 1% if you redeem  within the first year of purchase.  They are subject
to a distribution  (Rule 12b-1) fee at an annual rate of .75% of the Portfolio's
average daily net assets attributable to Class C Shares. In addition,  an annual
shareholder  servicing  fee  calculated  at  an  annual  rate  of  .25%  of  the
Portfolio's  average daily net assets attributable to its Class C Shares will be
paid by Class C shareholders.  Class C Shares provide an investor the benefit of
putting all of the  investor's  dollars to work from the time the  investment is
made but will have a higher expense ratio and generally will pay lower dividends
than  Class A Shares  due to the  distribution  fee on Class C  Shares.  Class C
Shares will  automatically  convert to Class A Shares twelve years after the end
of the calendar  month in which the  investor's  order to purchase was accepted.
See "How to Purchase Shares--Class C Share Information."

(a)  The sales charge  applicable to Class A Shares set forth in the above table
     is the maximum charge imposed upon the purchase of shares. Shareholders may
     pay less than 4.75%  depending on the amount  invested in Class A Shares of
     the Fund. See "How to Purchase Shares--Class A Share Information."
(b)  Class A purchases of $1 million or more are not subject to an initial sales
     charge; however, a contingent deferred sales charge of 1% may be imposed on
     certain  redemptions within one year following such purchases.  See "How to
     Purchase  Shares--Class A Share  Information."  For Class B purchases,  the
     amount of the contingent deferred sales charge, if applicable,  will depend
     on the number of years since the shareholder made the purchase payment. See
     "How to Purchase Shares--Class B Share Information." For Class C purchases,
     a  contingent  deferred  sales  charge of 1% may be imposed on  redemptions
     within one year following  purchase.  See "How to Purchase  Shares--Class C
     Share Information."
(c)  The Alger Fund pays Fred Alger & Company,  Incorporated for its services in
     distributing  Class B and Class C Shares of each Portfolio other than Alger
     Money Market  Portfolio  at the maximum  annual rate of .75% of the class's
     average  daily net assets.  Long-term  shareholders  paying Rule 12b-1 fees
     pursuant to The Alger  Fund's plans of  distribution  may pay more than the
     economic equivalent of the maximum front-end sales charges permitted by the
     rules of the National Association of Securities Dealers, Inc.
   
(d)  Included in Other Expenses of Alger Capital Appreciation Portfolio is 0.08%
     of interest  expense  for Class A Shares and 0.11% of interest  expense for
     Class B and Class C Shares.
    
(e)  Other Expenses for a Portfolio's  Class C Shares are estimated on the basis
     of  amounts  incurred  by the  Portfolio's  Class B Shares  during its most
     recent fiscal year.

                             HOW TO PURCHASE SHARES

In General

   
   The  Alger  Fund  (the  "Fund")  offers  Class A,  Class B and Class C Shares
(except for Alger Money Market Portfolio which has a single class of shares) for
investors.  The  offering  price for Class A Shares is net asset  value  plus an
initial  sales  charge that  declines for larger  purchases  (see "Class A Share
Information"  below).  Purchases  of Class A Shares in  amounts of $1 million or
more incur no initial  sales charge but may be subject to a contingent  deferred
sales charge  ("CDSC") if held for less than one year.  The  offering  price for
Class B Shares is net asset value with no initial  sales  charge but such shares
may be  subject  to a CDSC if held  for  less  than  six  years.  Class B Shares
automatically  convert  to Class A Shares  after  they  have been held for eight
years (see "Class B Share Information"  below).  Class C shares also are sold at
net asset value without an initial  sales  charge,  but they may be subject to a
CDSC of 1% if held for less than one year. Class C Shares automatically  convert
to Class A Shares after they have been held for twelve years (see "Class C Share
Information"  below).  Alger Money  Market  Portfolio is sold without an initial
sales  charge or CDSC.  There is no minimum  imposed  on  initial or  subsequent
investments  in any  Portfolio  other than Alger  Money  Market  Portfolio.  The
minimum  initial  investment  in Alger  Money  Market  Portfolio  is  $500,  and
subsequent  investments must be at least $25. These minimums may be waived under
certain  circumstances.  The Fund or the transfer  agent may reject any purchase
order.

 PROCESSING ORGANIZATIONS

broker-dealer, bank or other financial institution that purchases shares for its

Organization   in  conjunction   with  this   Prospectus.   Certain   Processing
Organizations may receive  compensation from the Fund, Alger Inc., or any of its
affiliates.

CLASS A SHARE INFORMATION

   Class A Shares are  available  in all  Portfolios  except  Alger Money Market
Portfolio.  These shares may be subject to an initial  sales  charge  (indicated
below) on purchases of less than $1 million.  Purchases of Class A Shares in the
amount of $1 million or more avoid the initial sales charge,  but are subject to
a CDSC of 1% if held for less  than one year.  See  "Contingent  Deferred  Sales
Charge" below.

 INITIAL SALES CHARGE

   The sales charges applicable to purchases of Class A Shares of the Portfolios
(other than the Alger Money Market Portfolio) are:

                            Sales Charge     Sales Charge       Dealer Allowance
     Purchase                 as % of         as % of               as % of
      Amount               Offering Price   Net Asset Value      Offering Price
- -------------------        --------------   ---------------     ----------------
Less than $100,000            4.75%            4.99%               4.00%
$100,000 - $249,999           4.00%            4.17%               3.25%
$250,000 - $499,999           3.00%            3.09%               2.50%
$500,000 - $999,999           2.25%            2.30%               1.75%
$1,000,000 and over             *                *                 1.00%

   
- ------------------
*  Purchases of Class A Shares,  which when  combined  with current  holdings of
   Class A Shares  offered with a sales charge equal to or exceeding  $1,000,000
   in the  aggregate,  may be made at net asset value  without any initial sales
   charge,  but will be subject to a CDSC of 1.00% on redemptions made within 12
   months of purchase. The CDSC is waived in certain circumstances. See "Waivers
   of Sales Charges."
    

                                       1
<PAGE>

   The reduced  sales charges shown above apply to the aggregate of purchases of
Class A Shares  of the Fund  made at one time  (unless  a Letter of Intent is on
file with the Fund) by "any person," which  includes an  individual,  his or her
spouse and children,  or a trustee or other fiduciary of a single trust,  estate
or single fiduciary account. See "Letter of Intent."

   From  time  to  time  Alger  Inc.   may  reallow  to  brokers  or   financial
intermediaries  all or  substantially  all of the initial sales  charge.  To the
extent that it does so, such  persons  may be deemed to be  underwriters  of the
Fund as defined in the Securities Act of 1933, as amended.

 RIGHT OF ACCUMULATION

   Class A Shares  of the Fund may be  purchased  by "any  person"  (as  defined
above) at a reduced sales charge as determined by aggregating  the dollar amount
of the new  purchase and the current  value (at  offering  price) of all Class A
Shares  of the Fund then  held by such  person  and  applying  the sales  charge
applicable to such  aggregate.  In order to obtain such discount,  the purchaser
must  provide  sufficient   information  at  the  time  of  purchase  to  permit
verification that the purchase qualifies for the reduced sales charge. The right
of accumulation is subject to  modification or  discontinuance  at any time with
respect to all shares purchased thereafter.

 LETTER OF INTENT

   A Letter of Intent ("LOI")  contemplating  aggregate purchases of $100,000 or
more provides an opportunity for an investor to obtain a reduced sales charge by
aggregating  investments  over a 13-month  period,  provided  that the  investor
refers to such LOI when placing  orders.  For  purposes of a LOI, the  "Purchase
Amount" as referred to in the preceding sales charge table includes purchases of
all Class A Shares of the Fund offered with a sales charge over the following 13
months.  An alternative is to compute the 13-month period starting up to 90 days
before the date of execution of the LOI.

   The minimum initial  investment  under the LOI is 5% of the total LOI amount.
Each  investment  made  during the period  receives  the  reduced  sales  charge
applicable to the total amount of the investment goal. Shares purchased with the
first 5% of the total LOI amount will be held in escrow by the Transfer Agent to
assure  any  necessary  payment  of a  higher  applicable  sales  charge  if the
investment goal is not met. If the goal is not achieved  within the period,  the
investor must pay the  difference  between the sales  charges  applicable to the
purchases  made and the charges  previously  paid, or an  appropriate  number of
escrowed shares will be redeemed.

CLASS B SHARE INFORMATION

   Class B Shares are  offered  for sale for  purchases  of less than  $250,000.
Class B Shares are sold at net asset value with no initial  sales  charge.  This
provides  investors  the benefit of putting all of their  dollars to work at the
time the investment is made.  However,  a CDSC of up to 5% may be imposed if you
redeem your shares within six years of purchase.  See "Contingent Deferred Sales
Charge."  Class B Shares are subject to certain  Rule 12b-1 fees as well,  which
are described  below.  Once Class B Shares have been held for eight years,  they
will  automatically  convert to Class A Shares.  See  "Conversion of Class B and
Class C Shares."

CLASS C SHARE INFORMATION

   Class C shares are offered for sale for  purchases  of less than  $1,000,000.
Class C Shares are sold at net asset value with no initial  sales  charge.  This
provides  investors  the benefit of putting all of their  dollars to work at the
time the investment is made.  However, a CDSC of 1% may be imposed if you redeem
your shares within one year of purchase. See "Contingent Deferred Sales Charge."
Class C Shares  are  subject  to  certain  Rule  12b-1  fees as well,  which are
described below.  Once Class C Shares have been held for twelve years, they will
automatically convert to Class A Shares. (See "Conversion of Class B and Class C
Shares.")

   Class C Shares are subject to the same ongoing  distribution and service fees
as Class B Shares but are  subject  to a CDSC for a shorter  period of time (one
year versus six years) than Class B Shares.  However,  Class B Shares convert to
Class A Shares  after a shorter  period  of time  than do Class C Shares  (eight
years versus twelve years).

   
CONVERSION OF CLASS B AND CLASS C SHARES

   Class B and Class C Shares will automatically convert to Class A Shares eight
and twelve years,

                                       2
<PAGE>


respectively, after the end of the calendar month in which the order to purchase
was accepted  and will  thereafter  not be subject to the original  Class's Rule
12b-1 fees.  The  conversion  will be completed on the basis of the relative net
asset values per share without the imposition of any sales charge,  fee or other
charge. At conversion,  a proportionate amount of shares representing reinvested
dividends  and  reinvested  capital  gains will also be  converted  into Class A
Shares.  Because Alger Money Market Portfolio is not subject to any distribution
fees,  the running of the  applicable  conversion  period is  suspended  for any
period  of time in which  shares  received  in  exchange  for Class B or Class C
Shares are held in that  Portfolio.  For purposes of determining  the conversion
date of Class B Shares  outstanding prior to August 1, 1997, such shares will be
deemed to have been held for either  eight years or the period  (adjusted as set
forth in the preceding sentence) since their purchase  acceptance,  whichever is
shorter. Accordingly, all Class B Shares outstanding for at least eight years as
of August 28, 1997 were converted to Class A Shares on August 28, 1997.
    

   The  conversion  of  Class B Shares  and  Class C Shares  is  subject  to the
continuing  availability  of an  opinion  of  counsel  to the  effect  that  the
conversion of shares does not  constitute a taxable  event under Federal  income
tax laws.  The conversion of Class B and Class C Shares may be suspended if such
an opinion is no longer available.

DISTRIBUTION PLANS

   The Fund has adopted separate  Distribution  Plans (the "Plans")  pursuant to
Rule 12b-1 under the Investment Company Act of 1940, as amended (the "1940 Act")
under which  Classes B and C of each  Portfolio  other than Alger  Money  Market
Portfolio may make payments to Alger Inc. in connection  with its  activities in
promoting  sales of that  Portfolio's  Class B and C Shares--at a maximum annual
rate of .75% of the  Portfolio's  average daily net assets  represented  by such
shares  (each a Rule 12b-1 fee).  Under the Class B Plan,  the Rule 12b-1 fee is
paid, up to the maximum annual rate, to the extent  necessary to reimburse Alger
Inc.'s expenses incurred in promoting  distribution of Class B shares. Under the
Class C Plan, the Rule 12b-1 fee constitutes  compensation to Alger Inc. for its
activities in distributing  Class C Shares,  and the expenses  incurred by Alger
Inc.  in  connection  with  such  activities  may be  greater  or less  than the
compensation  received  from the  Portfolio.  In each case,  the Rule 12b-1 fee,
sometimes  described as an "asset-based  sales charge," allows  investors to buy
shares  without an initial sales charge while  allowing Alger Inc. to compensate
dealers that sell Class B or C Shares of the Portfolios.  Typically, Alger Inc.,
in its discretion or pursuant to dealer agreements, pays sales commissions of up
to 4.75% of the amount  invested  in Class B Shares,  and up to 1% of the amount
invested in Class C Shares,  to dealers  from its own  resources  at the time of
sale and pays continuing  commissions  after purchase to dealers selling Class C
Shares.  For Class B Shares,  Alger Inc. retains the asset-based sales charge to
   
recoup the sales  commissions  and other  sales-related  expenses its pays.  For
Class C Shares,  the  asset-based  sales charge is retained by Alger Inc. in the
first year after purchase; in subsequent years, all or a portion of it typically
is paid to the dealers who sold the Class C Shares.  In some cases,  the selling
dealer is Alger Inc.  Any CDSCs on Class B Shares  received  by Alger Inc.  will
reduce the  amount to be  reimbursed  under the Class B Plan.  Under the Class B
Plan, any excess  distribution  expenses may be carried forward,  with interest,
and  reimbursed  in future  years.  At October 31,  1997,  the end of the Fund's
fiscal year, the following  approximate  amounts were carried  forward under the
Class B Plan: Alger Small  Capitalization  Portfolio--$16,444,000  (2.71% of net
assets);  Alger  MidCap  Growth  Portfolio--$3,218,000   (1.87%);  Alger  Growth
Portfolio--$7,605,000  (2.13%); Alger Balanced  Portfolio--$225,000 (1.71%); and
Alger Capital Appreciation Portfolio--$2,124,000 (.93%).

CONTINGENT DEFERRED SALES CHARGE

   No CDSC is  imposed  on the  redemption  of  shares  of  Alger  Money  Market
Portfolio,  except that shares


                                       3
<PAGE>

of the Portfolio acquired in exchange for shares of the other Portfolios will
bear any CDSC that would apply to the exchanged shares.
    

   With respect to Class B Shares, there is no initial sales charge on purchases
of shares of any  Portfolio,  but a CDSC may be charged on certain  redemptions.
The CDSC is imposed on any  redemption  that  causes the  current  value of your
account  in the  Class B shares of the  Portfolio  to fall  below the  amount of
purchase  payments  made  during a six-year  holding  period.  The amount of the
charge  is based  on the  length  of time  shares  are  held,  according  to the
following table:

                                                                    Contingent
                                                                  Deferred Sales
       Years Shares Were Held                                         Charge
  ----------------------------------                              --------------
Less than one ................................................          5%
One but less than two ........................................          4%
Two but less than three ......................................          3%
Three but less than four .....................................          2%
Four but less than five ......................................          2%
Five but less than six .......................................          1%
Six and greater ..............................................          0%

   Certain  Class A Shares  also are  subject  to a CDSC.  Those  Class A Shares
purchased  in an amount of $1 million or more which have not been subject to the
Class's  initial  sales  charge and which have not been held for a full year are
subject to a CDSC of 1% at the time of redemption.

   Class C Shares have no initial  sales  charge but are subject to a CDSC of 1%
if redeemed within one year of purchase.

   IN GENERAL

   For purposes of the CDSC, it is assumed that the shares of the Portfolio from
which  the  redemption  is made are the shares of that Portfolio which result in
the lowest charge, if any.

   Redemptions  of shares of each of the  Portfolios are deemed to be made first
from  amounts,  if any,  to  which a CDSC  does not  apply.  There is no CDSC on
redemptions  of  (i)  shares  that  represent   appreciation  on  your  original
investment,  or (ii) shares  purchased  through  reinvestment  of dividends  and
capital  gains.  Since no charge is imposed on shares  purchased and retained in
Alger Money Market Portfolio,  you may wish to consider  redeeming those shares,
if any,  before  redeeming  shares  that are  subject to a CDSC.  Please see the
Statement of Additional  Information  for examples of how the CDSC is calculated
when shares are exchanged.

this status at the time of redemption. Information regarding these procedures is
available by contacting the Fund at (800) 992-3863.

TELEPHONE REDEMPTIONS

   You  automatically  have the ability to make  redemptions by telephone unless
you refuse the  telephone  redemption  privilege.  To sell shares by  telephone,
please call (800) 992-3863.  If your redemption request is received before 12:00
noon Eastern time for Alger Money Market  Portfolio,  your  redemption  proceeds
will  generally  be mailed on the next  business  day.  Redemption  requests for
Portfolios other than Alger Money Market  Portfolio  received prior to the close
of business of the NYSE  (normally  4:00 p.m.  Eastern  time) will  generally be
mailed on the next business day. Requests received after 12:00 noon Eastern time
for Alger Money Market  Portfolio  will  generally be mailed on the business day
following the next business day.  Shares held in any Alger  retirement  plan and
shares issued in certificate form are not eligible for this service.
    
   Redemption  proceeds  are mailed to the  address of record.  Any  request for
redemption  proceeds to be sent to the address of record must be in writing with
the  signature(s)  guaranteed  if made within 60 days of changing  your address.
Redemption  requests  made before 12:00 noon Eastern time for Alger Money Market
Portfolio will not receive a dividend for that day.

   The Fund, the Transfer  Agent and their  affiliates are not liable for acting
in good faith on telephone  instructions  relating to your  account,  so long as
they follow reasonable  procedures to determine that the telephone  instructions
are genuine.  Such  procedures  may include  recording the  telephone  calls and
requiring some form of personal  identification.  You should verify the accuracy
of  telephone  transactions   immediately  upon  receipt  of  your  confirmation
statement.

CHECK REDEMPTIONS (ALGER MONEY MARKET PORTFOLIO ONLY)
   
   You may redeem shares in your Alger Money Market Portfolio account by writing
a check for at least $500.  Dividends are earned until the check clears.  If you
mark the appropriate  box on the New Account  Application and sign the signature
card, the Fund will send you redemption checks. There is no charge for the first
five checks you write in any one calendar  year.  You will be charged  $2.50 for
each additional check you write.

   Your  redemption  may be  reduced  by any  applicable  CDSC (see  "Contingent
Deferred Sales Charge").  If your account is not adequate to cover the amount of
your  check  and  any  applicable  CDSC,  the  check  will  be  returned  marked
insufficient funds. As a result,  checks should not be used to close an account.
Shares held in any Alger  retirement plan and shares issued in certificate  form
are not eligible for this service.

   The use of the check redemption  procedure  does  not give  rise to a banking
relationship between the shareholder and the Fund or  the Transfer  Agent, which
will be acting solely as transfer agent for the Portfolio.

REDEMPTION IN KIND

   Under unusual circumstances, shares of a Portfolio may be redeemed "in kind,"
which means that the redemption  proceeds will be paid with securities which are
held by the Portfolio.  Please refer to the Statement of Additional  Information
for more details.
    

   
                            SPECIAL INVESTOR SERVICES
EXCHANGE PRIVILEGE

   Except as  limited  below,  shareholders  may  exchange  some or all of their
shares for shares of another  Portfolio of the Fund.  Class A  shareholders  may
exchange  their shares for Class A Shares of another  Portfolio or for shares of
Alger Money Market Portfolio. Class B shareholders may exchange their shares for
Class B  Shares  of  another  Portfolio  or for  shares  of Alger  Money  Market
Portfolio.  Class C shareholders may exchange their shares for Class C Shares of
another  Portfolio  or for shares of Alger Money Market  Portfolio.  Alger Money
Market  Portfolio  shares acquired by direct purchase may be exchanged for Class
A, Class B or Class C Shares of another Portfolio; however, any applicable sales
charge will apply to the shares acquired,  depending upon their class. Shares of
Alger Money Market Portfolio acquired by exchange rather than by direct purchase
may be  exchanged  for shares of another  Portfolio,  but only for shares of the
same  class as those  originally  exchanged  for Alger  Money  Market  Portfolio
shares. The period

of time shares are held in Alger Money Market  Portfolio shall not be considered
in  scheduling  of the  automatic  conversion to Class A Shares or, for accounts
opened after October 17, 1992, in the calculation of a CDSC.

   You automatically  have the ability to make exchanges by telephone unless you
refuse the telephone exchange privilege.  Exchanges can be made among Portfolios
of the  same  class of  shares  for  identically  registered  accounts.  For tax
purposes,  an  exchange  of shares is treated as a sale of the shares  exchanged
and, therefore, you may realize a taxable gain or loss when you exchange shares.
Shares  exchanged prior to the close of business of the NYSE (normally 4:00 p.m.
Eastern  time) from Alger Money  Market  Portfolio to any other  Portfolio  will
receive dividends from Alger Money Market Portfolio for the day of the exchange.
Shares of Alger Money  Market  Portfolio  received in exchange for shares of any
other Portfolio will earn dividends beginning on the next business day after the
exchange.

    You may make up to six  exchanges  annually by telephone or in writing.  The
Fund may charge a transaction fee for each exchange, although it does not intend
to do so at  present.  You will be  notified  at least 60 days in advance if the
Fund  decides to impose this fee.  The Fund  reserves  the right to terminate or
modify the exchange privilege upon notice to shareholders.

AUTOMATIC INVESTMENT PLAN

    The Fund  offers an  Automatic  Investment  Plan which  permits  you to make
regular  transfers  to your Fund  account  from your  bank  account  on the last
business day of every month.  The minimum monthly  investment  amount is $25 per
Portfolio. Your bank must be a member of the Automated Clearing House.
    

AUTOMATIC EXCHANGE PLAN

   The Fund also offers an Automatic Exchange Plan which permits you to exchange
a specified  amount from your Alger Money Market  Portfolio  account into one or
more of the other  Portfolios on or about the  fifteenth  day of the month.  The
minimum monthly exchange amount is $25 per Portfolio.

REINSTATEMENT PRIVILEGE

   A shareholder  who has redeemed  shares of a Portfolio may, within 30 days of
the  redemption,  reinstate  any  portion  or all of the  net  proceeds  of such
redemption   in  Portfolio   shares  of  the  same  class  by  exercise  of  the
Reinstatement  Privilege.  Reinvestment  will be at the net  asset  value of the
Portfolio  next  determined  upon receipt of the proceeds and letter  requesting
this privilege be exercised, subject to confirmation of the shareholder's status
or holdings, as the case may be. You will also receive a pro rata credit for any
CDSC  imposed.  This  privilege  may be  exercised  only once by a  shareholder.
Exercising  the  Reinstatement  Privilege  will not alter any tax payable on the
redemption and a loss may not be allowed for tax purposes.

                              INVESTMENT OBJECTIVES
                                  AND POLICIES

   The investment  objectives of the Portfolios and the investment  restrictions
summarized in the next paragraph are  fundamental  which means that they may not
be changed without shareholder  approval.  All investment policies and practices
described  elsewhere in this  Prospectus  are not  fundamental,  which means the
Fund's Board of Trustees may change them without shareholder approval.  There is
no guarantee that any Portfolio's objectives will be achieved.

   As a matter of fundamental policy, no Portfolio will: (1) with respect to 75%
of its total assets,  invest more than 5% of its total assets in any one issuer,
except for obligations issued or guaranteed by the U.S. Government, its agencies
or instrumentalities  ("U.S. Government  securities");  (2) own more than 10% of
the outstanding voting securities of any company;  (3) invest more than 10% (15%
for Alger Capital  Appreciation  Portfolio) of its net assets in securities that
are  illiquid by virtue of legal or  contractual  restrictions  on resale or the
absence of a readily  available  market;  (4) invest  more than 25% of its total
assets in any one  industry,  except for U.S.  Government  securities  and, with
respect to Alger Money Market Portfolio, bank and thrift obligations; (5) borrow
money or pledge its assets, except that it may borrow money or pledge its assets
in an  amount  of up to 10% of its  total  assets  for  temporary  or  emergency
purposes and that Alger Capital Appreciation Portfolio may borrow for investment
purposes as described  below under "Alger Capital  Appreciation  Portfolio." The
Statement of Additional Information contains additional investment  restrictions
as well as additional information on the Portfolios' investment practices.

   Except in the case of percentage  limitations  on borrowing by the Portfolios
and as may be otherwise  stated,  the  percentage  limitations  contained in the
Fund's investment  restrictions and other investment  policies apply at the time
of  purchase  of a security,  and a later  increase  or  decrease in  percentage
resulting  from  a  change  in  value  of  securities  or in the  amount  of the
Portfolio's assets will not constitute a violation of the restriction or policy.

   
   In order to permit sales of shares  in certain  jurisdictions,  the  Fund may
commit to policies  more  restrictive  than those stated above, and the Fund may
terminate any such commitment by discontinuing sales of shares in the applicable
jurisdiction. 
    

ALGER MONEY MARKET PORTFOLIO

   The  investment  objective of the Portfolio is to earn high current  income
consistent  with  preservation  of principal and  maintenance of liquidity.  The
Portfolio may invest in "money market"  instruments  including,  certificates of
deposit,  time deposits and bankers'  acceptances;  U.S. Government  securities;
corporate bonds having less than 397 days remaining to maturity;  and commercial
paper, including variable rate master demand notes. The Portfolio may also enter
into repurchase  agreements,  reverse repurchase  agreements and firm commitment
agreements. The Statement of Additional Information contains more information on
these instruments.

   The  Portfolio  will invest at least 95% of its total  assets in money market
securities  which are rated within the highest  credit  category  assigned by at
least two  established  rating agencies (or one rating agency if the security is
rated by only one) and will only invest in money market  securities rated at the
time of purchase  within the two highest credit  categories or, if not rated, of
equivalent  investment  quality as  determined  by Fred Alger  Management,  Inc.
("Alger Management"),  the Fund's investment manager.  Alger Management subjects
all securities  eligible for investment to its own credit analysis and considers
all securities purchased by the Portfolio to present minimal credit risks.

   The Portfolio has a policy of  maintaining a stable net asset value of $1.00.
This policy has been maintained since its inception; however, the $1.00 price is
not  guaranteed  or insured,  nor is its yield fixed.


                                       8
<PAGE>

The Portfolio generally purchases  securities which mature in 13 months or less.
The  average  maturity  of the  Portfolio  will not be greater  than 90 days.  A
discussion  of rating  agencies is included in the Appendix to the  Statement of
Additional Information.

ALGER BALANCED PORTFOLIO

   The  investment  objective of the  Portfolio is current  income and long-term
capital  appreciation.  The  Portfolio  intends  to  invest  based  on  combined
considerations of risk, income,  capital  appreciation and protection of capital
value.  Normally,  it will invest in common  stocks and  investment  grade fixed
income securities  (preferred stock and debt securities),  as well as securities
convertible into common stocks.  Except during temporary defensive periods,  the
Portfolio will maintain at least 25% of its net assets in fixed income  (senior)
securities.  With respect to debt securities,  the Portfolio will invest only in
instruments  which are rated in one of the four highest rating categories by any
established  rating  agency,  or if not  rated,  which are  determined  by Alger
Management to be of comparable quality to instruments so rated.

   The  Portfolio  may  invest  up to 35% of its total  assets  in money  market
instruments  and repurchase  agreements and in excess of that amount (up to 100%
of its assets) during temporary defensive periods.

ALGER GROWTH PORTFOLIO

   The investment objective of the Portfolio is long-term capital  appreciation.
Except during temporary defensive periods, the Portfolio invests at least 65% of
its total assets in equity securities of companies that, at the time of purchase
of the securities,  have total market  capitalization--present  market value per
share  multiplied  by the total number of shares  outstanding--of  $1 billion or
greater.  Accordingly, the Portfolio may invest up to 35% of its total assets in
equity securities of companies that, at the time of purchase,  have total market
capitalization of less than $1 billion.

   
ALGER MIDCAP GROWTH PORTFOLIO

   The investment objective of the Portfolio is long-term capital  appreciation.
Except during temporary defensive periods, the Portfolio invests at least 65% of
its total assets in equity securities of companies that, at the time of purchase
of the  securities,  have  total  market  capitalization  within  the  range  of
companies  included  in the S&P  MidCap 400 Index,  updated  quarterly.  The S&P
MidCap 400 Index is designed to track the  performance of medium  capitalization
companies.  As of December 31, 1997, the range of market capitalization of these
companies  was $213 million to $13.737  billion.  The Portfolio may invest up to
35% of its total assets in equity  securities of companies  that, at the time of
purchase,  have  total  market  capitalization  outside  the range of  companies
included in the S&P MidCap 400 Index and in excess of that amount (up to 100% of
its assets) during temporary defensive periods.
    
   
ALGER SMALL CAPITALIZATION PORTFOLIO

   The investment objective of the Portfolio is long-term capital  appreciation.
Except during temporary defensive periods, the Portfolio invests at least 65% of
its total assets in equity securities of companies that, at the time of purchase
of the  securities,  have  total  market  capitalization  within  the  range  of
companies included in the Russell 2000 Growth Index ("Russell Index") or the S&P
SmallCap  600 Index ("S&P  Index"),  updated  quarterly.  Both indexes are broad
indexes of small  capitalization  stocks.  As of December 31, 1997, the range of
market  capitalization  of the companies in the Russell Index was $20 million to
$2.97 billion;  the range of market  capitalization  of the companies in the S&P
Index at that date was $21 million to $2.934  billion.  The combined range as of
that date was $20 million to $2.97  billion.  The Portfolio may invest up to 35%
of its total  assets in equity  securities  of  companies  that,  at the time of
purchase,  have total market capitalization  outside this combined range, and in
excess of that  amount (up to 100% of its  assets)  during  temporary  defensive
periods.

ALGER CAPITAL APPRECIATION PORTFOLIO

   The investment objective of the Portfolio is long-term capital  appreciation.
Except during temporary defensive periods, the Portfolio invests at least 85% of
its net assets in equity securities of companies of any size.


                                       9
<PAGE>


   The Portfolio may purchase put and call options and sell (write) covered call
and put options on  securities  and  securities  indexes to increase gain and to
hedge  against  the risk of  unfavorable  price  movements,  and may enter  into
futures  contracts  on  securities  indexes and  purchase  and sell call and put
options  on  these  futures  contracts.  The  Portfolio  may also  borrow  money
(leverage) for the purchase of additional  securities.  The Portfolio may borrow
only from banks and may not borrow in excess of one-third of the market value of
its total assets,  less liabilities  other than such borrowing.  These practices
are deemed to be speculative and may cause the Portfolio's net asset value to be
more  volatile  than the net asset value of a fund that does not engage in these
activities. See "Investment Practices."

IN GENERAL

   Alger Small Capitalization  Portfolio,  Alger MidCap Growth Portfolio,  Alger
Growth Portfolio,  Alger Capital Appreciation Portfolio,  and the equity portion
of Alger  Balanced  Portfolio  seek to achieve their  objectives by investing in
equity securities, such as common or preferred stocks, or securities convertible
into or exchangeable for equity  securities,  including warrants and rights. The
Portfolios  will invest  primarily in companies  whose  securities are traded on
domestic stock exchanges or in the over-the-counter  market. These companies may
still be in the  developmental  stage,  may be older companies that appear to be
entering  a new stage of growth  progress  owing to factors  such as  management
changes  or  development  of  new  technology,  products  or  markets  or may be
companies providing products or services with a high unit volume growth rate. In
order  to  afford  the  Portfolios  the  flexibility  to take  advantage  of new
opportunities for investments in accordance with their investment objectives and
to meet  redemptions,  they may hold up to 15% of their net assets (35% of total
assets, in the case of Alger Balanced Portfolio) in money market instruments and
repurchase  agreements and in excess of that amount (up to 100% of their assets)
during  temporary  defensive  periods.  This  amount  may be  higher  than  that
maintained by other funds with similar investment objectives.

    
   Investing in smaller,  newer  issuers  generally  involves  greater risk than
investing in larger,  more established  issuers.  Companies in which Alger Small
Capitalization  Portfolio  is likely to invest may have limited  product  lines,
markets or financial  resources and may lack management depth. The securities of
such companies may have limited  marketability and may be subject to more abrupt
or  erratic  market  movements  than  securities  of  larger,  more  established
companies or the market averages in general.  Accordingly,  an investment in the
Portfolio may not be appropriate  for all investors.  These risks may also apply
to investments in smaller  companies by all other Portfolios  except Alger Money
Market Portfolio.

                              INVESTMENT PRACTICES

   The Portfolios  may use the investment  strategies and invest in the types of
securities  described  below,  which may involve certain risks. The Statement of
Additional  Information contains more detailed information about these practices
and information about other investment practices of the Portfolios.

REPURCHASE AGREEMENTS

   In a  repurchase  agreement,  a  Portfolio  buys a security  at one price and
simultaneously  agrees  to sell it back at a  higher  price.  In the  event of a
bankruptcy  or  default  of the other  party to the  repurchase  agreement,  the
Portfolio  could  experience  costs and  delays in  liquidating  the  underlying
security,  which is held as collateral,  and the Portfolio might incur a loss if
the value of the collateral held declines during this period.

ILLIQUID AND RESTRICTED SECURITIES

   An  investment  may be illiquid  because of the absence of an active  trading
market,  making  it  difficult  to  sell  promptly  at an  acceptable  price.  A
restricted  security is one that has a contractual  restriction on its resale or
which cannot be sold publicly until it is registered under the Securities Act of
1933. Each Portfolio may purchase securities eligible for resale under Rule 144A
of the Securities Act of 1933. This rule permits otherwise restricted securities
to be sold to certain  institutional  buyers.  Under the policies and procedures
established  by the Fund's Board of Trustees,  Alger  Management  determines the
liquidity of the Portfolios' Rule 144A investments.


                                       10

<PAGE>


LENDING OF PORTFOLIO SECURITIES

   
   In order to generate income and to offset  expenses,  each Portfolio may lend
portfolio  securities with a value up to 331/3% of the Portfolio's total assets,
including  all  collateral  on such  loans  less  liabilities  exclusive  of the
obligation to return such  collateral,  to brokers,  dealers and other financial
organizations. Any such loan will be continuously secured by collateral at least
equal to the value of the  securities  loaned.  Default  by the  borrower  could
result  in  delays,  costs  and/or  losses in  disposing  of the  collateral  or
recovering  the loaned  securities  and,  should the borrower fail  financially,
possible loss of rights in the collateral.
    

FOREIGN SECURITIES

   Each Portfolio  other than Alger Money Market  Portfolio may invest up to 20%
of its total assets in foreign  securities.  Investing in  securities of foreign
companies and foreign  governments,  which  generally are denominated in foreign
currencies,   may  involve  certain  risk  and  opportunity  considerations  not
typically  associated  with investing in domestic  companies and could cause the
Portfolio  to be  affected  favorably  or  unfavorably  by changes  in  currency
exchange rates and revaluations of currencies.

   Each Portfolio may purchase American Depositary  Receipts ("ADRs"),  American
Depositary  Shares ("ADSs"),  or U.S.  dollar-denominated  securities of foreign
issuers,  none of which are included in the 20% foreign  securities  limitation.
ADRs and ADSs are  traded  in the U.S.  securities  markets  and  represent  the
securities  of  foreign  issuers.  While  ADRs and ADSs may not  necessarily  be
denominated in the same currency as the foreign securities they represent,  many
of the risks associated with foreign securities may also apply to ADRs and ADSs.

LEVERAGE THROUGH BORROWING

   Alger Capital  Appreciation  Portfolio may borrow money from banks and use it
to  purchase  additional  securities.  This  borrowing  is known as  leveraging.
Leverage  increases both  investment  opportunity  and  investment  risk. If the
investment gains on securities purchased with borrowed money exceed the interest
paid on the borrowing,  the net asset value of the Portfolio's  shares will rise
faster than would  otherwise be the case. On the other hand,  if the  investment
gains fail to cover the cost (including interest) of borrowings, or if there are
losses,  the net asset value of the Portfolio's shares will decrease faster than
would  otherwise be the case.  The Portfolio is required to maintain  continuous
asset coverage (that is, total assets  including  borrowings,  less  liabilities
exclusive of borrowings) of 300% of the amount borrowed.  If such asset coverage
should decline below 300% as a result of market  fluctuations  or other reasons,
the  Portfolio  may be required to sell some of its  portfolio  holdings  within
three days to reduce the debt and restore the 300% asset  coverage,  even though
it may be  disadvantageous  from an investment  standpoint to sell securities at
that time.

OPTIONS

   Alger Capital Appreciation Portfolio may buy and sell (write) exchange listed
options  in order to  obtain  additional  return  or to hedge  the  value of its
portfolio.  Hedging  transactions  are  intended  to  reduce  the  risk of price
fluctuations. The Portfolio may write an option on a security only if the option
is  "covered"  (for a  discussion  of  covered  options,  see the  Statement  of
Additional Information). Although the Portfolio will generally purchase or write
only those  options for which there  appears to be an active  secondary  market,
there is no assurance that a liquid  secondary  market on an exchange will exist
for any  particular  option.  The Portfolio  will not purchase  options if, as a
result,  the  aggregate  cost  of all  outstanding  options  exceeds  10% of the
Portfolio's  total  assets,  although  no more  than 5%  will  be  committed  to
transactions entered into for non-hedging  purposes.  The Portfolio may purchase
and sell put and call  options on stock  indexes in order to increase  its gross
income or to hedge its portfolio against price fluctuations.

   The writing and purchase of options are highly  specialized  activities which
involve  investment  techniques and risks  different from those  associated with
ordinary portfolio securities transactions. Additional discussion of these risks
and techniques is included in the Statement of Additional Information.


                                       11

<PAGE>

STOCK INDEX FUTURES AND OPTIONS ON
STOCK INDEX FUTURES

   Alger  Capital  Appreciation  Portfolio  may  purchase  and sell stock  index
futures  contracts  and  options  on  stock  index  futures   contracts.   These
investments may be made only for hedging, not speculative, purposes.

   There can be no assurance of the  Portfolio's  successful  use of stock index
futures as a hedging device.  If Alger  Management uses a hedging  instrument at
the wrong time or judges market conditions  incorrectly,  hedging strategies may
reduce the Portfolio's return. The Portfolio could also experience losses if the
prices of its futures and options  positions were not correlated  with its other
investments  or if it could not  close out a  position  because  of an  illiquid
market for the future or option.

PORTFOLIO TURNOVER

   Portfolio changes will generally be made without regard to the length of time
a security  has been held or  whether a sale  would  result in a profit or loss.
Higher levels of portfolio activity generally result in higher transaction costs
and may  also  result  in  taxes on  realized  capital  gains to be borne by the
Portfolio's shareholders.


                             MANAGEMENT OF THE FUND

ORGANIZATION

   The Fund was  organized  on March 20,  1986 as a  multi-series  Massachusetts
business  trust.  The Fund offers an  unlimited  number of shares of six series,
representing  its shares of the  Portfolios.  With the  exception of Alger Money
Market Portfolio, each Portfolio offers three classes of shares.

   Although the Fund is not required by law to hold annual shareholder meetings,
it may hold meetings from time to time on important  matters,  and  shareholders
have the right to call a meeting  to remove a Trustee  or to take  other  action
described in the Fund's Declaration of Trust.  Shareholders of one Portfolio may
vote only on matters that affect that  Portfolio.  Shareholders  of a class have
exclusive  voting rights with respect to matters  affecting only that class, and
shareholders  vote  separately by class on matters in which the interests of one
class differ from those of another.

BOARD OF TRUSTEES

   The  Fund is  governed  by a Board  of  Trustees  which  is  responsible  for
protecting the interests of shareholders under  Massachusetts law. The Statement
of Additional  Information  contains general  background  information about each
Trustee and officer of the Fund.

INVESTMENT MANAGER

   Alger Management is the Fund's investment  manager and is responsible for the
overall  administration of the Fund,  subject to the supervision of the Board of
Trustees. Alger Management makes investment decisions for the Portfolios, places
orders to purchase and sell  securities on behalf of the  Portfolios and selects
broker-dealers  that, in its judgment,  provide prompt and reliable execution at
favorable prices and reasonable  commission  rates. It is anticipated that Alger
Inc.  will  serve as the Fund's  broker in  effecting  substantially  all of the
Portfolios'  transactions on securities exchanges and will retain commissions in
accordance with certain  regulations of the Securities and Exchange  Commission.
The Fund will  consider  sales of its  shares as a factor  in the  selection  of
broker-dealers to execute  over-the-counter  portfolio transactions,  subject to
the  requirements  of best price and execution.  In addition,  Alger  Management
employs   professional   securities   analysts  who  provide  research  services
exclusively to the  Portfolios and other accounts for which Alger  Management or
its affiliates serve as investment adviser or subadviser.

   
   Alger  Management has been in the business of providing  investment  advisory
services since 1964 and, as of January 31, 1998, had approximately  $7.8 billion
under management, $4.5 billion in mutual fund accounts and $3.3 billion in other
advisory  accounts.  Alger  Management  is owned by Alger Inc.  which in turn is
owned by Alger Associates,  Inc., a financial services holding company.  Fred M.
Alger,  III and his brother,  David D. Alger,  are the majority  shareholders of
Alger  Associates,  Inc.  and may be  deemed to  control  that  company  and its
subsidiaries.

SHAREHOLDER SERVICING AGREEMENT

   The Fund pays Alger Inc. a  shareholder  servicing fee of .25% of the average
daily net assets of each  Portfolio  other than Alger Money Market Portfolio for
ongoing  service  and  maintenance  of shareholder  accounts.  Alger  Inc.  will
compensate  dealers  from  this fee who provide personal service and maintenance
of customer accounts.

                                 NET ASSET VALUE

   The price of one share of a class is based on its "net asset  value." The net
asset value is computed by adding the value of the Portfolio's  investments plus
cash and other assets allocable to the class,  deducting applicable  liabilities
and then  dividing the result by the number of its shares  outstanding.  The net
asset  value of a share of a given  class  may  differ  from that of one or more
other  classes.  Net  asset  value is  calculated  as of the  close of  business
(normally 4:00 p.m.  Eastern time) or, for Alger Money Market  Portfolio,  as of
12:00 noon Eastern time on each day the NYSE is open.

   Purchases for Alger Money Market Portfolio will be processed at the net asset
value calculated after your order is received and accepted.  If your purchase is
made by wire and is received by 12:00 noon  Eastern  time,  your account will be
credited  and  begin  earning  dividends  on the day of  receipt.  If your  wire
purchase is received  after 12:00 noon  Eastern  time,  it will be credited  and
begin earning  dividends  the next business day.  Exchanges are credited the day
the request is received by mail or telephone,  and begin  earning  dividends the
next business day. If your purchase is made by check,  and received by the close
of business of the NYSE (normally 4:00 p.m.  Eastern time),  it will be credited
and begin earning dividends the next business day.

   Purchases  for the  other  Portfolios  will be based  upon the next net asset
value  calculated  for each class after your order is received and accepted.  If
your purchase is made by check, wire or exchange and is received by the close of
business of the NYSE  (normally 4:00 p.m.  Eastern  time),  your account will be
credited on the day of receipt. If your purchase is received after such time, it
will be credited the next business day.

   Third-party   checks   will   not  be   honored   except   in  the   case  of
employer-sponsored  retirement  plans.  You will be  charged a fee for any check
returned by your bank.


                               DIVIDENDS AND TAXES

DIVIDENDS

   Each class will be treated separately in determining the amounts of dividends
of investment  income and  distributions  of capital gains payable to holders of
its shares.  Dividends and distributions will be automatically reinvested at net
asset value on the payment date in additional  shares of the class that paid the
dividend or  distribution  at net asset value,  unless you elected in writing to
have all  dividends  and  distributions  paid in cash or reinvested at net asset
value into  another  identically  registered  Alger  Portfolio  account you have
established. In addition, accounts whose dividend/distribution  checks have been
returned as undeliverable shall reinvest that  dividend/distribution  at the net
asset value next  determined  after the Transfer Agent receives the  undelivered
check. Furthermore,  all future dividend/distribution checks shall be reinvested
automatically at net asset value on the payment date until a written request for
reinstatement  of cash  distribution and a valid mailing address are provided by
the  shareholder(s).  Shares  purchased  through  reinvestment  of dividends and
distributions are not subject to a CDSC or front-end sales charge. Any dividends
of Alger Money Market  Portfolio are declared  daily and paid  monthly,  and any
dividends of the other Portfolios are declared and paid annually.  Distributions
of any net realized short-term and long-term capital gains earned by a Portfolio
usually  will be made  annually  after the close of the fiscal year in which the
gains are earned.

   The classes of a  Portfolio  may have  different  dividend  and  distribution
rates. Class A dividends generally will be greater than those of Classes B and C
due to the Rule  12b-1  fees  associated  with  Class B and C  Shares.  However,
dividends  paid to each class of shares in a Portfolio will be declared and paid
at the same time and will be determined in the same manner as those paid to each
other class.

TAXES

   Each  Portfolio  intends  to qualify  and elect to be treated  each year as a
"regulated  investment  company" for federal  income tax  purposes.  A regulated
investment company is not subject to regular income tax on


                                       14

<PAGE>

any income or capital gains  distributed to its  shareholders if it, among other
things, distributes at least 90 percent of its investment company taxable income
to them within applicable time periods.  Each Portfolio is treated as a separate
taxable entity,  with the result that taxable dividends and distributions from a
Portfolio reflect only the income and gains, net of losses, of that Portfolio.

   For federal income tax purposes  dividends and distributions from a Portfolio
are taxable to you whether paid in cash or reinvested in additional  shares. You
may also be liable for tax on any gain realized upon the  redemption or exchange
of shares in the Portfolios.

   Shortly after the close of each calendar  year,  you will receive a statement
setting  forth the dollar  amounts of dividends  and any  distributions  for the
prior  calendar year and the tax status of the dividends and  distributions  for
federal  income tax purposes.  You should consult your tax adviser to assess the
federal,  state and local tax consequences of investing in each Portfolio.  This
discussion is not intended to address the tax consequences of an investment by a
nonresident alien.


                                   PERFORMANCE

   The Portfolios and their  underlying  classes  advertise  different  types of
yield  and  total  return  performance.  All  performance  figures  are based on
historical earnings and are not intended to indicate future  performance.  Yield
and total  return  figures may be  different  among the classes of a  portfolio.
Further  information  about the Fund's  performance  is  contained in its Annual
Report to  Shareholders,  which may be obtained without charge by contacting the
Fund.

   
   Alger Money Market Portfolio may advertise its "yield" and "effective yield."
The "yield" of the Portfolio refers to certain income generated by an investment
in  the  Portfolio  over  a  particular   base  period.   This  income  is  then
"annualized."  That is, the amount of income generated by the investment  during
the period is assumed to be  generated  over a 52 week  period and is shown as a
percentage of the investment. The "effective yield" is calculated similarly but,
when annualized,  the income earned by an investment in the Portfolio is assumed
to be reinvested. The "effective yield" will be slightly higher than the "yield"
because of the compounding effect on this assumed reinvestment.
    

   Each of the classes of the Portfolios other than Alger Money Market Portfolio
may also include quotations of their "total return" in advertisements or reports
to  shareholders  or  prospective  investors.  Total  return  figures  show  the
aggregate or average percentage change in value of an investment in a class from
the beginning date of the measuring  period to the end of the measuring  period.
These figures reflect changes in the price of the class's shares and assume that
any income dividends and/or capital gains distributions made by the class during
the period were  reinvested  in shares of the class.  Figures  will be given for
recent 1, 5, and 10 year  periods,  and may be given for other  periods  as well
(such as from  commencement  of the  class's  operations,  or on a  year-by-year
basis) and may utilize  dollar  cost  averaging.  The class may use  "aggregate"
total return figures for various periods,  representing the cumulative change in
value of an  investment in the class for the specific  period (again  reflecting
changes  in class  share  price  and  assuming  reinvestment  of  dividends  and
distributions) as well as "actual annual" and "annualized" total return figures.
Total returns may be calculated either with or without the effect of the CDSC or
initial  sales  charge to which the shares are subject and may be shown by means
of  schedules,  charts or graphs,  and may  indicate  subtotals  of the  various
components of total return (i.e., change in value of initial investment,  income
dividends and capital  gains  distributions).  "Total  return" and "yield" for a
class will vary based on changes in market  conditions.  In addition,  since the
deduction  of a class's  expenses  is  reflected  in the total  return and yield
figures,  "total  return" and  "yield"  will also vary based on the level of the
class's expenses.

   The Statement of Additional Information,  which is incorporated by reference,
further  describes  the method  used to  determine  the yields and total  return
figures.  Current  yield  and/or  total  return  quotations  may be  obtained by
contacting the Fund.

                                  INTRODUCTION

   The Alger Fund's portfolios,  other than Alger Money Market Portfolio,  offer
three classes of shares having  different sales charges,  ongoing fees and other
features.  You may purchase the class of shares that is most  beneficial  to you
based  upon the  amount of the  purchase,  the length of time you expect to hold
shares and other circumstances.

Class A Shares

   An investor  purchasing  Class A Shares may pay a sales charge at the time of
purchase.  Class A Shares  are not  subject to a charge  when they are  redeemed
(except for shares  purchased  for total  proceeds of $1 million or more,  which
have no initial  sales charge and which may be subject to a contingent  deferred
sales charge  ["CDSC"]).  The initial  sales charge may be reduced or waived for
certain  purchases.  Class A Shares are subject to a  shareholder  servicing fee
equal to an annual  rate of .25% of the  Portfolio's  average  daily net  assets
attributable to its Class A Shares.  See "How to Purchase  Shares--Class A Share
Information."

Class B Shares

   Class B Shares are  offered  for sale for  purchases  of less than  $250,000.
Class B Shares have no initial sales charge,  but may be subject to a CDSC of up
to 5% if you  redeem  within  six  years  of  purchase.  They are  subject  to a
distribution  (Rule  12b-1)  fee at an  annual  rate of .75% of the  Portfolio's
average daily net assets attributable to Class B Shares. Class B Shares also pay
a  shareholder  servicing  fee  calculated  at an  annual  rate  of  .25% of the
Portfolio's average daily net assets attributable to its Class B Shares. Class B
Shares provide an investor the benefit of putting all of the investor's  dollars
to work  from the time the  investment  is made but will  have a higher  expense
ratio and  generally  will pay lower  dividends  than  Class A Shares due to the
distribution fee on Class B Shares. Class B Shares will automatically convert to
Class A Shares  eight  years  after the end of the  calendar  month in which the
investor's order to purchase was accepted.  See "How to Purchase Shares--Class B
Share Information."

Class C Shares

   Class C Shares are offered for sale for  purchases  of less than  $1,000,000.
There is no initial sales charge for Class C Shares,  but they may be subject to
a CDSC of 1% if you redeem  within the first year of purchase.  They are subject
to a distribution  (Rule 12b-1) fee at an annual rate of .75% of the Portfolio's
average daily net assets attributable to Class C Shares. In addition,  an annual
shareholder  servicing  fee  calculated  at  an  annual  rate  of  .25%  of  the
Portfolio's  average daily net assets attributable to its Class C Shares will be
paid by Class C shareholders.  Class C Shares provide an investor the benefit of
putting all of the  investor's  dollars to work from the time the  investment is
made but will have a higher expense ratio and generally will pay lower dividends
than  Class A Shares  due to the  distribution  fee on Class C  Shares.  Class C
Shares will  automatically  convert to Class A Shares twelve years after the end
of the calendar  month in which the  investor's  order to purchase was accepted.
See "How to Purchase Shares--Class C Share Information."

PORTFOLIO EXPENSES
   The table  below is designed  to assist you in  understanding  the direct and
indirect  costs and expenses  that you will bear as a  shareholder.  The Example
accompanying  the Table shows the amount of  expenses  you would pay on a $1,000
investment in each class of shares of the  Portfolio.  These amounts  assume the
reinvestment  of all  dividends  and  distributions,  payment of any  applicable
initial or  contingent  deferred  sales  charges and payment by the Portfolio of
operating  expenses  as shown in the  Table  under  Annual  Portfolio  Operating
Expenses. The Example is an illustration only and actual expenses may be greater
or less than those shown.

</TABLE>

(a)  The sales charge  applicable to Class A Shares set forth in the above table
     is the maximum charge imposed upon the purchase of shares. Shareholders may
     pay less than 4.75%  depending on the amount  invested in Class A Shares of
     the Fund. See "How to Purchase Shares--Class A Share Information."
(b)  Class A purchases of $1 million or more are not subject to an initial sales
     charge; however, a contingent deferred sales charge of 1% may be imposed on
     certain  redemptions within one year following such purchases.  See "How to
     Purchase  Shares--Class A Share  Information."  For Class B purchases,  the
     amount of the contingent deferred sales charge, if applicable,  will depend
     on the number of years since the shareholder made the purchase payment. See
     "How to Purchase Shares--Class B Share Information." For Class C purchases,
     a  contingent  deferred  sales  charge of 1% may be imposed on  redemptions
     within one year following  purchase.  See "How to Purchase  Shares--Class C
     Share Information."
(c)  The Alger Fund pays Fred Alger & Company,  Incorporated for its services in
     distributing  Class B and Class C Shares of each Portfolio other than Alger
     Money Market  Portfolio  at the maximum  annual rate of .75% of the class's
     average  daily net assets.  Long-term  shareholders  paying Rule 12b-1 fees
     pursuant to The Alger  Fund's plans of  distribution  may pay more than the
     economic equivalent of the maximum front-end sales charges permitted by the
     rules of the National Association of Securities Dealers, Inc.

(d)  Other Expenses for the Portfolio's Class A and Class C Shares are estimated
     on the basis of amounts  incurred by the Portfolio's  Class B Shares during
     its most recent fiscal year.

                             HOW TO PURCHASE SHARES

   
IN GENERAL
   The Fund offers Class A, Class B and Class C Shares of Alger Growth Portfolio
(the  "Portfolio")  for investors.  The offering price for Class A Shares is net
asset value plus an initial sales charge that declines for larger purchases (see
"Class A Share Information" below). Purchases of Class A Shares in amounts of $1
million or more incur no initial sales charge but may be subject to a contingent
deferred  sales  charge  ("CDSC") if held for less than one year.  The  offering
price for Class B Shares is net asset  value  with no initial  sales  charge but
such  shares may be  subject to a CDSC if held for less than six years.  Class B
Shares  automatically  convert  to Class A Shares  after they have been held for
eight years (see  "Class B Share  Information"  below).  Class C shares also are
sold at net asset value without an initial sales charge, but they may be subject
to a CDSC of 1% if held for less  than one  year.  Class C Shares  automatically
convert to Class A Shares after they have been held for twelve years (see "Class
C Share  Information"  below).  The Fund or the  transfer  agent may  reject any
purchase order.

agreements  with the Fund's  Distributor,  Fred  Alger &  Company,  Incorporated
("Alger Inc.").

   PROCESSING ORGANIZATIONS

   You  can  buy  shares  through  a  "Processing  Organization",   which  is  a
broker-dealer, bank or other financial institution that purchases shares for its
customers.  Processing  Organizations  may impose  charges and  restrictions  in
addition  to or  different  from those  applicable  if you invest  with the Fund
directly.  Therefore,  you should read the materials  provided by the Processing
Organization   in  conjunction   with  this   Prospectus.   Certain   Processing
Organizations may receive  compensation from the Fund, Alger Inc., or any of its
affiliates.

CLASS A SHARE INFORMATION

   Class A Shares may be subject to an initial sales charge (indicated below) on
purchases of less than $1 million.  Purchases of Class A Shares in the amount of
$1 million or more avoid the initial sales charge,  but are subject to a CDSC of
1% if held for less than one year. See "Contingent Deferred Sales Charge" below.

   INITIAL SALES CHARGE

   The sales charges  applicable to purchases of Class A Shares of the Portfolio
are:

                           Sales Charge     Sales Charge        Dealer Allowance
     Purchase                 as % of         as % of              as % of

- ------------------        --------------   ---------------      ----------------
Less than $100,000             4.75%            4.99%                4.00%

$500,000 - $999,999            2.25%            2.30%                1.75%
$1,000,000 and over              *                *                  1.00%
- ------------------
*  Purchases of Class A Shares,  which when  combined  with current  holdings of
   Class A Shares  offered with a sales charge equal to or exceeding  $1,000,000
   in the  aggregate,  may be made at net asset value  without any initial sales
   charge,  but will be subject to a CDSC of 1.00% on redemptions made within 12
   months of purchase. The CDSC is waived in certain circumstances. See "Waivers
   of Sales Charges."

   The reduced  sales charges shown above apply to the aggregate of purchases of
Class A Shares  made at one time  (unless a Letter of Intent is on file with the
Fund) by "any  person,"  which  includes  an  individual,  his or her spouse and
children,  or a trustee or other  fiduciary of a single trust,  estate or single
fiduciary account. See "Letter of Intent."

   From  time  to  time  Alger  Inc.   may  reallow  to  brokers  or   financial
intermediaries  all or  substantially  all of the initial sales  charge.  To the
extent that it does so, such  persons  may be deemed to be  underwriters  of the
Fund as defined in the Securities Act of 1933, as amended.


   RIGHT OF ACCUMULATION

   Class A Shares may be  purchased  by "any  person"  (as  defined  above) at a
reduced sales charge as determined by  aggregating  the dollar amount of the new
purchase and the current  value (at  offering  price) of all Class A Shares then
held by such person and applying the sales charge  applicable to such aggregate.
In  order to  obtain  such  discount,  the  purchaser  must  provide  sufficient
information  at the time of purchase to permit  verification  that the  purchase
qualifies for the reduced sales charge.  The right of accumulation is subject to
modification or  discontinuance at any time with respect to all shares purchased
thereafter.


   LETTER OF INTENT

   A Letter of Intent ("LOI")  contemplating  aggregate purchases of $100,000 or
more provides an opportunity for an investor to obtain a reduced sales charge by
aggregating  investments  over a 13-month  period,  provided  that the  investor
refers to such LOI when placing  orders.  For purposes of the LOI, the "Purchase
Amount" as referred to in the preceding sales charge table includes purchases of
all Class A Shares of the Fund offered with a sales charge over the following 13
months.  An alternative is to compute the 13-month period starting up to 90 days
before the date of execution of the LOI.

   The minimum initial  investment  under the LOI is 5% of the total LOI amount.
Each  investment  made  during the period  receives  the  reduced  sales  charge
applicable to the total amount of the investment goal. Shares purchased with the
first 5% of the total LOI amount will be held in escrow by the Transfer Agent to
assure  any  necessary  payment  of a  higher  applicable  sales  charge  if the
investment goal is not met. If the goal is not achieved  within the period,  the
investor must pay the  difference  between the sales  charges  applicable to the
purchases  made and the charges  previously  paid, or an  appropriate  number of
escrowed shares will be redeemed.


Class B Share Information

   Class B Shares are offered for sale for purchases of less than $250,000.Class
B Shares are sold at net asset value with no initial sales charge. This provides
investors  the benefit of putting all of their  dollars to work at the time  the
investment  is made.  However,  a CDSC of up to 5% may be  imposed if you redeem
your shares within six years of purchase.See "Contingent Deferred Sales Charge."
Class B Shares are subject to  certain  Rule  12b-1  fees  as  well,  which  are
described below. Once  Class B  Shares  have  been  held  for eight  years, they
will automatically  convert to Class A Shares. See "Conversion of  Class  B  and
Class C Shares."




                                       2
<PAGE>

Class C Share Information

   Class C Shares are offered for sale for  purchases  of less than  $1,000,000.
Class C Shares are sold at net asset value with no initial  sales  charge.  This
provides  investors  the benefit of putting all of their  dollars to work at the
time the investment is made.  However, a CDSC of 1% may be imposed if you redeem
your shares within one year of purchase. See "Contingent Deferred Sales Charge."
Class C Shares  are  subject  to  certain  Rule  12b-1  fees as well,  which are
described below.  Once Class C Shares have been held for twelve years, they will
automatically convert to Class A Shares. (See "Conversion of Class B and Class C
Shares.")

   Class C Shares are subject to the same ongoing  distribution and service fees
as Class B Shares but are  subject  to a CDSC for a shorter  period of time (one
year versus six years) than Class B Shares.  However,  Class B Shares convert to
Class A Shares  after a shorter  period  of time  than do Class C Shares  (eight
years versus twelve years).

CONVERSION OF CLASS B AND CLASS C SHARES

   
   Class B and Class C Shares will automatically convert to Class A Shares eight
and twelve years, respectively, after the end of the calendar month in which the
order to  purchase  was  accepted  and will  thereafter  not be  subject  to the
original  Class's Rule 12b-1 fees. The conversion will be completed on the basis
of the relative net asset values per share  without the  imposition of any sales
charge,  fee or other charge.  At conversion,  a proportionate  amount of shares
representing  reinvested  dividends  and  reinvested  capital gains will also be
converted  into Class A Shares.  Because  Alger Money  Market  Portfolio  is not
subject to any  distribution  fees,  the  running of the  applicable  conversion
period is suspended for any period of time in which shares  received in exchange
for  Class B or  Class C Shares  are held in that  Portfolio.  For  purposes  of
determining the conversion date of Class B Shares outstanding prior to August 1,
1997, such shares will be deemed to have been held for either eight years or the
period  (adjusted as set forth in the preceding  sentence)  since their purchase
acceptance,  whichever is shorter.  Accordingly,  all Class B Shares outstanding
for at least eight years as of August 28, 1997 were  converted to Class A Shares
on August 28, 1997.
    

   
   The  conversion  of Class  B Shares  and  Class C Shares is  subject  to  the
continuing  availability  of an opinion  of  counsel  to  the  effect  that  the
conversion of shares does not  constitute a taxable event under  Federal  income
tax laws. The conversion of Class B and Class C Shares may be suspended if  such
an opinion is no longer available.
    

DISTRIBUTION PLANS

   The Fund has adopted separate  Distribution  Plans (the "Plans")  pursuant to
Rule 12b-1 under the Investment Company Act of 1940, as amended (the "1940 Act")
under which  Classes B and C of the Portfolio may make payments to Alger Inc. in
connection with its activities in promoting sales of the Portfolio's Class B and
C Shares--at a maximum annual rate of .75% of the Portfolio's  average daily net
assets  represented  by such shares  (each a Rule 12b-1 fee).  Under the Class B
Plan,  the Rule 12b-1 fee is paid, up to the maximum  annual rate, to the extent
necessary to reimburse Alger Inc.'s expenses incurred in promoting  distribution
of Class B  shares.  Under  the Class C Plan,  the Rule  12b-1  fee  constitutes
compensation  to Alger Inc. for its activities in  distributing  Class C Shares,
and the expenses  incurred by Alger Inc. in connection  with such activities may
be greater or less than the  compensation  received from the Portfolio.  In each
case, the Rule 12b-1 fee, sometimes  described as an "asset-based sales charge,"
allows  investors to buy shares  without an initial sales charge while  allowing
Alger Inc. to compensate dealers that sell Class B or C Shares of the Portfolio.
Typically, Alger Inc., in its discretion or pursuant to dealer agreements,  pays
sales  commissions of up to 4.75% of the amount invested in Class B Shares,  and
up to 1% of the  amount




                                       3
<PAGE>

   
invested in Class C Shares,  to dealers  from its own  resources  at the time of
sale and pays continuing  commissions  after purchase to dealers selling Class C
Shares.  For Class B Shares,  Alger Inc. retains the asset-based sales charge to
recoup the sales  commissions  and other  sales-related  expenses its pays.  For
Class C Shares,  the  asset-based  sales charge is retained by Alger Inc. in the
first year after purchase; in subsequent years, all or a portion of it typically
is paid to the dealers who sold the Class C Shares.  In some cases,  the selling
dealer is Alger Inc.  Any CDSCs on Class B Shares  received  by Alger Inc.  will
reduce the  amount to be  reimbursed  under the Class B Plan.  Under the Class B
Plan, any excess  distribution  expenses may be carried forward,  with interest,
and  reimbursed  in future  years.  At October 31,  1997,  the end of the Fund's
fiscal year, approximately $7,605,000 (2.13%) was carried forward under the Plan
on behalf of the Portfolio.
    

CONTINGENT DEFERRED SALES CHARGE

   
   No CDSC is  imposed  on the  redemption  of  shares  of  Alger  Money  Market
Portfolio,  except that shares of the Portfolio acquired for shares of the other
Portfolios will bear any CDSC that would apply to the exchanged shares.
    

   With respect to Class B Shares, there is no initial sales charge on purchases
of shares of the  Portfolio,  but a CDSC may be charged on certain  redemptions.
The CDSC is imposed on any  redemption  that  causes the  current  value of your
account  in the  Class B shares of the  Portfolio  to fall  below the  amount of
purchase  payments  made  during a six-year  holding  period.  The amount of the
charge  is based  on the  length  of time  shares  are  held,  according  to the
following table:

                                                                    Contingent
                                                                  Deferred Sales
       Years Shares Were Held                                         Charge
- ----------------------------------                                --------------
Less than one .................................................          5%
One but less than two .........................................          4%
Two but less than three .......................................          3%
Three but less than four ......................................          2%
Four but less than five .......................................          2%
Five but less than six ........................................          1%
Six and greater ...............................................          0%

   Certain  Class A Shares  also are  subject  to a CDSC.  Those  Class A Shares
purchased  in an amount of $1 million or more which have not been subject to the
Class's  initial  sales  charge and which have not been held for a full year are
subject to a CDSC of 1% at the time of redemption.

   Class C Shares have no initial  sales  charge but are subject to a CDSC of 1%
if redeemed within one year of purchase. 

   IN GENERAL

   For purposes of the CDSC, it is assumed that the shares of the Portfolio from
which the  redemption is made are the shares of that  Portfolio  which result in
the lowest charge, if any.

   Redemptions  of shares of the  Portfolio  are  deemed to be made  first  from
amounts, if any, to which a CDSC does not apply. There is no CDSC on redemptions
of (i) shares that represent  appreciation on your original investment,  or (ii)
shares purchased through  reinvestment of dividends and capital gains.  Since no
charge is  imposed  on shares  purchased  and  retained  in Alger  Money  Market
Portfolio,  you may wish to consider  redeeming  those  shares,  if any,  before
redeeming  shares  that are  subject  to a CDSC.  Please  see the  Statement  of
Additional  Information  for examples of how the CDSC is calculated  when shares
are exchanged.

   
WAIVERS OF SALES CHARGES
   No initial  sales charge  (Class A) or CDSC (Classes A, B or C) is imposed on
(1) purchases or redemptions by (i) employees of Alger Inc. and its  affiliates,
(ii) IRAs,  Keogh Plans and employee benefit plans for those employees and (iii)
spouses,  children,  siblings and parents of those employees and trusts of which
those individuals are beneficiaries,  as long as orders for the shares on behalf
of those  individuals and trusts were placed by the employees;  (2) purchases or
redemptions by (i) accounts managed by investment  advisory  affiliates of Alger
Inc. that are registered under the Investment  Advisers Act of 1940, as amended,
(ii) employees,  participants and  beneficiaries of those accounts,  (iii) IRAs,
Keogh Plans and employee  benefit plans for those
    


                                       4
<PAGE>

employees, participants and beneficiaries and (iv) spouses and minor children of
those employees, participants and beneficiaries as long as orders for the shares
were placed by the employees,  participants and beneficiaries;  (3) purchases or
redemptions by directors or trustees of any  investment  company for which Alger
Inc. or any of its affiliates serves as investment  adviser or distributor;  (4)
purchases or redemptions of shares held through  defined  contribution  plans as
defined  by  ERISA;  (5)  purchases  or  redemptions  by an  investment  company
registered  under  the  1940  Act in  connection  with  the  combination  of the
investment  company  with the Fund by  merger,  acquisition  of assets or by any
other  transaction;  (6)  purchases  or  redemptions  by  registered  investment
advisers,  banks,  trust companies and other financial  institutions  exercising
discretionary  authority with respect to the money invested in Fund shares;  (7)
purchases  or  redemptions  by  registered  investment  advisers  for  their own
accounts;  (8)  purchases  or  redemptions  by  a  Processing  Organization,  as
shareholder  of  record,  on  behalf of (i)  investment  advisers  or  financial
planners trading for their own accounts or the accounts of their clients and who
charge  a  management,  consulting  or  other  fee for  their  services  ("wrap"
accounts); and clients of such investment advisers or financial planners trading
for their own accounts if the accounts are linked to the master  account of such
investment  adviser  or  financial  planner  on the  books  and  records  of the
Processing Organization, and (ii) retirement and deferred compensation plans and
trusts used to fund those plans;  and (9) purchases or redemptions by registered
representatives  of  broker-dealers  which have  entered  into  Selected  Dealer
Agreements with Alger Inc., and their spouses, children, siblings and parents.

   Any CDSC is also  waived on (1)  Systematic  Withdrawal  Plan  payments,  (2)
redemptions  of shares  in  connection  with  certain  required  post-retirement
withdrawals  from an IRA or other  retirement plan or (3) redemptions  following
the death or disability of a shareholder.

   Investors  purchasing Class A Shares subject to one of the foregoing  waivers
are required to claim and substantiate  their  eligibility for the waiver at the
time of purchase. It is also the responsibility of shareholders redeeming shares
otherwise  subject to a CDSC but qualifying for a waiver of the charge to assert
this status at the time of redemption. Information regarding these procedures is
available by contacting the Fund at (800) 992-3863.

                               HOW TO SELL SHARES
   You can sell  (redeem)  some or all of your shares on any business  day. Your

made by check within  seven days. A CDSC may be charged on certain  redemptions.
See "Contingent  Deferred Sales Charge" above,  for details.  Redemptions may be
suspended  and  payments  delayed  under  certain  emergency   circumstances  as
determined by the Securities and Exchange Commission.  The Fund's Transfer Agent

                            SPECIAL INVESTOR SERVICES
EXCHANGE PRIVILEGE

   
   Except as  limited  below,  shareholders  may  exchange  some or all of their
Portfolio  shares  for  shares  of  another  portfolio  of  the  Fund.  Class  A
shareholders  may exchange their shares for Class A Shares of another  portfolio
or for shares of Alger Money Market Portfolio. Class B shareholders may exchange
their  shares  for Class B Shares of  another  portfolio  or for shares of Alger
Money Market Portfolio. Class C shareholders may exchange their shares for Class
C Shares of another  portfolio  or for shares of Alger Money  Market  Portfolio.
Alger Money Market Portfolio shares acquired by direct purchase may be exchanged
for  Class A , Class B or Class C Shares  of  another  portfolio;  however,  any
applicable sales charge will apply to the shares acquired,  depending upon their
class.  Shares of Alger Money Market Portfolio  acquired by exchange rather than
by direct  purchase may be exchanged for shares of another  portfolio,  but only
for  shares of the same  class as those  originally  exchanged  for Alger  Money
Market  Portfolio  shares.  The period of time  shares  are held in Alger  Money
Market  Portfolio  shall  not be  considered  in  scheduling  of  the  automatic
conversion to Class A Shares or, for accounts  opened after October 17, 1992, in
the calculation of a CDSC.

   You automatically  have the ability to make exchanges by telephone unless you
refuse the telephone exchange privilege.  Exchanges can be made among portfolios
of the  same  class of  shares  for  identically  registered  accounts.  For tax
purposes,  an  exchange  of shares is treated as a sale of the shares  exchanged
and, therefore, you may realize a taxable gain or loss when you exchange shares.
Shares ex-

changed prior to the close of business of the NYSE (normally  4:00 p.m.  Eastern
time) from Alger Money  Market  Portfolio  to any other  portfolio  will receive
dividends from Alger Money Market Portfolio for the day of the exchange.  Shares
of Alger Money  Market  Portfolio  received in exchange  for shares of any other
portfolio  will earn  dividends  beginning  on the next  business  day after the
exchange.
    

   You may make up to six  exchanges  annually by telephone  or in writing.  The
Fund may charge a transaction fee for each exchange, although it does not intend
to do so at  present.  You will be  notified  at least 60 days in advance if the
Fund  decides to impose this fee.  The Fund  reserves  the right to terminate or
modify the exchange privilege upon notice to shareholders.

   The Fund  offers an  Automatic  Investment  Plan  which  permits  you to make
regular  transfers  to your Fund  account  from your  bank  account  on the last

portfolio. Your bank must be a member of the Automated Clearing House.

AUTOMATIC EXCHANGE PLAN

   Shares of the Portfolio are  available as an investment  for your  retirement
plans, including regular IRAs, Keogh Plans, corporate pension and profit-sharing
plans, Simplified Employee Pension IRAs, SIMPLE IRAs, Roth IRAs, Education IRAs,
401(k) Plans and 403(b) Plans. Please call the Fund at (800) 992-3863 to receive
the appropriate  documents which contain important information and applications.
    

SYSTEMATIC WITHDRAWAL PLAN

   
   If your  account  balance  in the  Portfolio  is  $10,000  or  more,  you may
establish a Systematic  Withdrawal Plan to receive payments of at least $50 on a
monthly,  quarterly  or annual  basis,  without  payment of a CDSC.  The maximum
monthly  withdrawal is one percent of the current account value in the Portfolio
at the time you begin participation in the Plan. Shares held in certificate form

REINSTATEMENT PRIVILEGE
   A shareholder who has redeemed shares of the Portfolio may, within 30 days of
the  redemption,  reinstate  any  portion  or all of the  net  proceeds  of such
redemption   in  Portfolio   shares  of  the  same  class  by  exercise  of  the
Reinstatement  Privilege.  Reinvestment  will be at the net  asset  value of the
Portfolio  next  determined  upon receipt of the proceeds and letter  requesting
this privilege be exercised, subject to confirmation of the shareholder's status
or holdings, as the case may be. You will also receive a pro rata credit for any
CDSC  imposed.  This  privilege  may be  exercised  only once by a  shareholder.
Exercising  the  Reinstatement  Privilege  will not alter any tax payable on the
redemption and a loss may not be allowed for tax purposes.

                              INVESTMENT OBJECTIVES
                                  AND POLICIES

   The  investment  objective of the Portfolio and the  investment  restrictions
summarized in the next paragraph are  fundamental  which means that they may not
be changed without shareholder  approval.  All investment policies and practices
described  elsewhere in this  Prospectus  are not  fundamental,  which means the
Fund's Board of Trustees may change them without shareholder approval.  There is
no guarantee that the Portfolio's objectives will be achieved.

   As a matter of fundamental  policy,  the Portfolio will not: (1) with respect
to 75% of its total  assets,  invest more than 5% of its total assets in any one
issuer, except for obligations issued or guaranteed by the U.S. Government,  its
agencies or instrumentalities ("U.S. Government securities");  (2) own more than
10% of the outstanding  voting  securities of any company;  (3) invest more than
10% of its net  assets in  securities  that are  illiquid  by virtue of legal or
contractual restrictions on resale or the absence of a readily available market;
(4) invest  more than 25% of its total  assets in any one  industry,  except for
U.S. Government  securities;  (5) borrow money or pledge its assets, except that
it may borrow  money or pledge its assets in an amount of up to 10% of its total
assets  for  temporary  or  emergency  purposes.  The  Statement  of  Additional
Information  contains additional  investment  restrictions as well as additional
information on the Portfolio's investment practices.

   Except in the case of  percentage  limitations  on borrowing by the Portfolio
and as may be otherwise  stated,  the  percentage  limitations  contained in the
Fund's investment  restrictions and other investment  policies apply at the time
of  purchase  of a security,  and a later  increase  or  decrease in  percentage
resulting  from  a  change  in  value  of  securities  or in the  amount  of the
Portfolio's assets will not constitute a violation of the restriction or policy.

   
   In order to permit  sales of shares in  certain  jurisdictions,  the Fund may
commit to policies more  restrictive  than those stated above,  and the Fund may
terminate  any  such  commitments  by  discontinuing  sales  of  shares  in  the
applicable jurisdiction.
    

   The investment objective of the Portfolio is long-term capital  appreciation.
Except during temporary defensive periods, the Portfolio invests at least 65% of
its total assets in equity securities of companies that, at the time of purchase
of the securities,  have total market  capitalization--present  market value per
share  multiplied  by the total number of shares  outstanding--of  $1 billion or
greater.  Accordingly, the Portfolio may invest up to 35% of its total assets in
equity securities of companies that, at the time of purchase,  have total market
capitalization of less than $1 billion.

IN GENERAL

   The  Portfolio  seeks  to  achieve  its  objective  by  investing  in  equity
securities,  such as common or preferred stocks, or securities  convertible into
or  exchangeable  for equity  securities,  including  warrants  and rights.  The
Portfolio  will invest  primarily in companies  whose  securities  are traded on
domestic stock exchanges or in the over-the-counter  market. These companies may
still be in the  developmental  stage,  may be older companies that appear to be
entering  a new stage of growth  progress  owing to factors  such as  management
changes  or  development  of  new  technology,  products  or  markets  or may be
companies providing products or services with a high unit volume growth rate. In
order  to  afford  the  Portfolio  the  flexibility  to  take  advantage  of new
opportunities  for investments in accordance with its investment  objectives and
to meet  redemptions,  it may hold up to 15% of its net  assets in money  market
instruments  and repurchase  agreements and in excess of that amount (up to 100%
of its assets) during  temporary  defensive  periods.  This amount may be higher
than that maintained by other funds with similar investment objectives.


   Investing in smaller,  newer  issuers  generally  involves  greater risk than
investing in larger,  more established  issuers.  Some of the companies in which
the  Portfolio is likely to invest may have limited  product  lines,  markets or
financial  resources  and may lack  management  depth.  The  securities  of such
companies  may have limited  marketability  and may be subject to more abrupt or
erratic market movements than securities of larger,  more established  companies
or the market averages in general.  Accordingly,  an investment in the Portfolio
may not be appropriate for all investors.

<PAGE>

                              INVESTMENT PRACTICES

    The Portfolio may use the  investment  strategies and invest in the types of
securities  described  below,  which may involve certain risks. The Statement of
Additional  Information contains more detailed information about these practices
and information about other investment practices of the Portfolio.


REPURCHASE AGREEMENTS
   In a repurchase  agreement,  the  Portfolio  buys a security at one price and
simultaneously  agrees  to sell it back at a  higher  price.  In the  event of a
bankruptcy  or  default  of the other  party to the  repurchase  agreement,  the
Portfolio  could  experience  costs and  delays in  liquidating  the  underlying
security,  which is held as collateral,  and the Portfolio might incur a loss if
the value of the  collateral  held  declines  during this  period.

ILLIQUID AND RESTRICTED SECURITIES
   An  investment  may be illiquid  because of the absence of an active  trading
market,  making  it  difficult  to  sell  promptly  at an  acceptable  price.  A
restricted  security is one that has a contractual  restriction on its resale or
which cannot be sold publicly until it is registered under the Securities Act of
1933. The Portfolio may purchase  securities eligible for resale under Rule 144A
of the Securities Act of 1933. This rule permits otherwise restricted securities
to be sold to certain  institutional  buyers.  Under the policies and procedures
established by the Fund's Board of Trustees, Fred Alger Management, Inc. ("Alger
Management")  determines the liquidity of the Portfolio's Rule 144A investments.

   
   LENDING OF  PORTFOLIO  SECURITIES  In order to generate  income and to offset
expenses,  the Portfolio may lend portfolio  securities with a value of up to 33
1/3% of the  Portfolio's  total assets  including  collateral on such loans less
liabilities  exclusive of the  obligation to return such  collateral to brokers,
dealers and other  financial  organizations.  Any such loan will be continuously
secured by  collateral  at least  equal to the value of the  securities  loaned.
Default by the borrower could result in delays, costs and/or losses in disposing
of the collateral or recovering the loaned  securities  and, should the borrower
fail financially, possible loss of rights in the collateral.
    

FOREIGN SECURITIES
   The Portfolio may invest up to 20% of its total assets in foreign securities.
Investing in securities  of foreign  companies  and foreign  governments,  which
generally are  denominated in foreign  currencies,  may involve certain risk and
opportunity  considerations not typically  associated with investing in domestic
companies and could cause the Portfolio to be affected  favorably or unfavorably
by changes in currency exchange rates and revaluations of currencies.

   The Portfolio may purchase American  Depositary  Receipts ("ADRs"),  American
Depositary  Shares ("ADSs"),  or U.S.  dollar-denominated  securities of foreign
issuers,  none of which are included in the 20% foreign  securities  limitation.
ADRs and ADSs are  traded  in the U.S.  securities  markets  and  represent  the
securities  of  foreign  issuers.  While  ADRs and ADSs may not  necessarily  be
denominated in the same currency as the foreign securities they represent,  many
of the risks associated with foreign securities may also apply to ADRs and ADSs.

PORTFOLIO TURNOVER
   Portfolio changes will generally be made without regard to the length of time
a security  has been held or  whether a sale  would  result in a profit or loss.
Higher levels of portfolio activity generally result in higher transaction costs
and may  also  result  in  taxes on  realized  capital  gains to be borne by the
Portfolio's shareholders.

                             MANAGEMENT OF THE FUND
ORGANIZATION
   The Fund was  organized  on March 20,  1986 as a  multi-series  Massachusetts
business  trust.  The Fund offers an  unlimited  number of shares of six series,
representing  its shares of the  portfolios.  With the  exception of Alger Money
Market Portfolio, each portfolio offers three classes of shares.

   Although the Fund is not required by law to hold annual shareholder meetings,
it may hold meetings from time to time on important  matters,  and  shareholders
have the right to call a meeting  to remove a Trustee  or to take  other  action
described in the

Fund's  Declaration  of Trust.  Shareholders  of one  portfolio may vote only on
matters  that  affect that  portfolio.  Shareholders  of a class have  exclusive
voting  rights  with  respect  to  matters   affecting  only  that  class,   and
shareholders  vote  separately by class on matters in which the interests of one
class differ from those of another.


BOARD OF TRUSTEES

   The  Fund is  governed  by a Board  of  Trustees  which  is  responsible  for
protecting the interests of shareholders under  Massachusetts law. The Statement
of Additional  Information  contains general  background  information about each
Trustee and officer of the Fund.

INVESTMENT MANAGER

   Alger Management is the Fund's investment  manager and is responsible for the
overall  administration of the Fund,  subject to the supervision of the Board of
Trustees. Alger Management makes investment decisions for the Portfolio,  places
orders to purchase and sell  securities  on behalf of the  Portfolio and selects
broker-dealers  that, in its judgment,  provide prompt and reliable execution at
favorable prices and reasonable  commission  rates. It is anticipated that Alger
Inc.  will  serve as the Fund's  broker in  effecting  substantially  all of the
Portfolio's  transactions on securities exchanges and will retain commissions in
accordance with certain  regulations of the Securities and Exchange  Commission.
The Fund will  consider  sales of its  shares as a factor  in the  selection  of
broker-dealers to execute  over-the-counter  portfolio transactions,  subject to
the  requirements  of best price and execution.  In addition,  Alger  Management
employs   professional   securities   analysts  who  provide  research  services
exclusively  to the  Fund's  portfolios  and  other  accounts  for  which  Alger
Management or its affiliates serve as investment adviser or subadviser.

   
   Alger  Management has been in the business of providing  investment  advisory
services since 1964 and, as of January 31, 1998, had approximately  $7.8 billion
under management, $4.5 billion in mutual fund accounts and $3.3 billion in other
advisory  accounts.  Alger  Management  is owned by Alger Inc.  which in turn is
owned by Alger Associates,  Inc., a financial services holding company.  Fred M.
Alger,  III and his brother,  David D. Alger,  are the majority  shareholders of
Alger  Associates,  Inc.  and may be  deemed to  control  that  company  and its
subsidiaries.
    

PORTFOLIO MANAGERS
    David D. Alger, Seilai Khoo and Ronald Tartaro are primarily responsible for
the  day-to-day  management of the  portfolios  of the Fund.  Mr. Alger has been
employed by Alger  Management  since  1971,  as  Executive  Vice  President  and
Director of Research  until 1995 and as President  since 1995. Ms. Khoo has been
employed by Alger Management since 1989, as a senior research analyst until 1995
and as a Senior Vice  President  since 1995.  Mr.  Tartaro has been  employed by
Alger  Management  since 1990, as a senior research  analyst until 1995 and as a
Senior Vice President since 1995. Mr. Alger, Ms. Khoo and Mr. Tartaro also serve
as portfolio managers for other mutual funds and investment  accounts managed by
Alger Management.

    Alger  Management  personnel  ("Access  Persons") are permitted to engage in
personal securities  transactions  subject to the restrictions and procedures of
the  Fund's  Code of Ethics.  Pursuant  to the Code of  Ethics,  Access  Persons
generally must preclear all personal  securities  transactions  prior to trading
and are subject to certain  prohibitions on personal trading. You can get a copy
of the Fund's Code of Ethics by calling the Fund toll-free at (800) 992-3863.


CERTAIN SHAREHOLDERS

   
     Set forth below is certain information regarding  significant  shareholders
of the Portfolio. At February 2, 1998, Merrill Lynch & Co. Trustee FBO Qualified
Retirement Plans owned beneficially or of record 32.07% of the Portfolio's class
A Shares, and Dreyfus Retirement Services owned beneficially or of record 37.34%
of the Portfolio's Class A Shares.  On that date,  Merrill Lynch Pierce Fenner &
Smith  FBO  its  Customers  owned  beneficially  or  of  record  29.01%  of  the
Portfolio's Class C Shares.  The shareholders  identified above may be deemed to
control  the  specified  Classes,  which may have the effect of  proportionately
diminishing the voting power of other shareholders of theses classes.
    

FEES AND EXPENSES
   The Portfolio pays Alger  Management a management fee computed daily and paid
monthly  at  annual  rates of .75%  based on a  percentage  of the  value of the
Portfolio's average daily net assets.



                                       10
<PAGE>


   The Portfolio pays other expenses  related to its daily  operations,  such as
custodian fees,  Trustees' fees, transfer agency fees, legal and auditing costs.
More information about the Portfolio's investment management agreement and other
expenses  paid by the  Portfolio  is included  in the  Statement  of  Additional
Information.

   The Statement of Additional Information contains information about the Fund's
brokerage policies and practices.

DISTRIBUTOR

   Alger Inc. serves as the Fund's distributor and also distributes  the  shares
of other mutual funds managed by Alger Management.

TRANSFER AGENT

   Alger Shareholder Services, Inc., an affiliate of Alger Management, serves as
transfer  agent  for  the  Fund.  Certain  record-keeping  services  that  would
otherwise be performed by Alger Shareholder  Services,  Inc. may be performed by
other entities  providing  similar services to their customers who invest in the
Fund.  The Fund,  Alger  Shareholder  Services,  Inc.,  Alger Inc. or any of its
affiliates may elect to enter into a contract to pay them for such services.

SHAREHOLDER SERVICING AGREEMENT

   The Fund pays Alger Inc. a shareholder  servicing  fee of .25% of the average
daily net assets of  the  Portfolio  for  ongoing  service  and  maintenance  of
shareholder  accounts.  Alger Inc.  will  compensate  dealers  from this fee who
provide  personal  service  and maintenance of customer accounts.

                                 NET ASSET VALUE

   The price of one share of a class is based on its "net asset  value." The net
asset value is computed by adding the value of the Portfolio's  investments plus
cash and other assets allocable to the class,  deducting applicable  liabilities
and then  dividing the result by the number of its shares  outstanding.  The net
asset  value of a share of a given  class  may  differ  from that of one or more
other  classes.  Net  asset  value is  calculated  as of the  close of  business
(normally 4:00 p.m. Eastern time).

   Purchases  for the  Portfolio  will be based  upon the next net  asset  value
calculated  for each class after your order is received  and  accepted.  If your
purchase  is made by check,  wire or  exchange  and is  received by the close of
business of the NYSE  (normally 4:00 p.m.  Eastern  time),  your account will be
credited on the day of receipt. If your purchase is received after such time, it
will be credited the next business day.

   Third-party   checks   will   not  be   honored   except   in  the   case  of
employer-sponsored  retirement  plans.  You will be  charged a fee for any check
returned by your bank.


                               DIVIDENDS AND TAXES

Dividends

   Each class will be treated separately in determining the amounts of dividends
of investment  income and  distributions  of capital gains payable to holders of
its shares.  Dividends and distributions will be automatically reinvested at net
asset value on the payment date in additional  shares of the class that paid the
dividend or  distribution  at net asset value,  unless you elected in writing to
have all  dividends  and  distributions  paid in cash or reinvested at net asset
value into  another  identically  registered  Alger  portfolio  account you have
established. In addition, accounts whose dividend/distribution  checks have been
returned as undeliverable shall reinvest that  dividend/distribution  at the net
asset value next  determined  after the Transfer Agent receives the  undelivered
check. Furthermore,  all future dividend/distribution checks shall be reinvested
automatically at net asset value on the payment date until a written request for
reinstatement  of cash  distribution and a valid mailing address are provided by
the  shareholder(s).  Shares  purchased  through  reinvestment  of dividends and
distributions are not subject to a CDSC or front-end sales charge. Any dividends
of the  Portfolio  are  declared  and paid  annually.  Distributions  of any net
realized  short-term and long-term capital gains earned by the Portfolio usually
will be made annually  after the close of the fiscal year in which the gains are
earned.




                                       11
<PAGE>

   The classes of the Portfolio  may have  different  dividend and  distribution
rates. Class A dividends generally will be greater than those of Classes B and C
due to the Rule  12b-1  fees  associated  with  Class B and C  Shares.  However,
dividends  paid to each class of shares in the  Portfolio  will be declared  and
paid at the same time and will be determined in the same manner as those paid to
each other class.

TAXES

   The  Portfolio  intends  to qualify  and elect to be  treated  each year as a
"regulated  investment  company" for federal  income tax  purposes.  A regulated
investment company is not subject to regular income tax on any income or capital
gains distributed to its shareholders if it, among other things,  distributes at
least 90  percent  of its  investment  company  taxable  income  to them  within
applicable time periods.  The Portfolio is treated as a separate taxable entity,
with the result that taxable  dividends  and  distributions  from the  Portfolio
reflect only the income and gains, net of losses, of that Portfolio.

   For  federal  income  tax  purposes  dividends  and  distributions  from  the
Portfolio  are taxable to you whether paid in cash or  reinvested  in additional
shares.  You may also be liable for tax on any gain realized upon the redemption
or exchange of shares in the Portfolio.

   Shortly after the close of each calendar  year,  you will receive a statement
setting  forth the dollar  amounts of dividends  and any  distributions  for the
prior  calendar year and the tax status of the dividends and  distributions  for
federal  income tax purposes.  You should consult your tax adviser to assess the
federal,  state and local tax  consequences of investing in the Portfolio.  This
discussion is not intended to address the tax consequences of an investment by a
nonresident alien.


                                   PERFORMANCE

   The Portfolio and its underlying  classes advertise  different types of yield
and total return  performance.  All performance  figures are based on historical
earnings and are not intended to indicate  future  performance.  Yield and total
return  figures  may be  different  among the  classes of a  portfolio.  Further
information about the Portfolio's  performance is contained in its Annual Report
to Shareholders, which may be obtained without charge by contacting the Fund.

   Each of the classes of the  Portfolio  may include  quotations  of its "total
return" in advertisements  or reports to shareholders or prospective  investors.
Total return figures show the aggregate or average percentage change in value of
an investment in a class from the beginning date of the measuring  period to the
end of the measuring  period.  These figures reflect changes in the price of the
class's  shares  and assume  that any  income  dividends  and/or  capital  gains
distributions  made by the class during the period were  reinvested in shares of
the class.  Figures will be given for recent 1, 5, and 10 year periods,  and may
be given for other  periods as well (such as from  commencement  of the  class's
operations,  or on a year-by-year  basis) and may utilize dollar cost averaging.
The  class  may use  "aggregate"  total  return  figures  for  various  periods,
representing  the  cumulative  change in value of an investment in the class for
the specific period (again reflecting  changes in class share price and assuming
reinvestment  of dividends  and  distributions)  as well as "actual  annual" and
"annualized"  total return figures.  Total returns may be calculated either with
or without  the effect of the CDSC or initial  sales  charge to which the shares
are subject and may be shown by means of  schedules,  charts or graphs,  and may
indicate  subtotals of the various  components of total return (i.e.,  change in
value of initial investment,  income dividends and capital gains distributions).
"Total  return"  and  "yield"  for a class  will vary based on changes in market
conditions.  In addition, since the deduction of a class's expenses is reflected
in the total return and yield figures, "total return" and "yield" will also vary
based on the level of the class's expenses.

   The Statement of Additional Information,  which is incorporated by reference,
further  describes  the method  used to  determine  the yields and total  return
figures.  Current  yield  and/or  total  return  quotations  may be  obtained by
contacting the Fund.

INVESTMENT OBJECTIVES AND POLICIES

CERTAIN SECURITIES AND INVESTMENT TECHNIQUES
The  Prospectus  discusses the  investment  objectives of each Portfolio and the
policies to be employed  to achieve  those  objectives.  This  section  contains
supplemental   information   concerning   the  types  of  securities  and  other
instruments  in which the Portfolios  may invest,  the  investment  policies and
portfolio strategies that the Portfolios may utilize and certain risks attendant
to those investments, policies and strategies.

U.S. GOVERNMENT OBLIGATIONS
Bills,  notes,  bonds, and other debt securities issued by the U.S. Treasury are
direct  obligations  of the U.S.  Government  and differ mainly in the length of
their maturities.

U.S. GOVERNMENT AGENCY SECURITIES
These  securities  are  issued  or  guaranteed  by  U.S.  Government   sponsored
enterprises and federal agencies. These include securities issued by the Federal
National Mortgage Association, Government National Mortgage Association, Federal
Home Loan Bank,  Federal  Land Banks,  Farmers  Home  Administration,  Banks for
Cooperatives,  Federal  Intermediate Credit Banks,  Federal Financing Bank, Farm
Credit Banks, the Small Business Administration,  Federal Housing Administration
and Maritime Administration.  Some of these securities are supported by the full
faith and credit of the U.S.  Treasury;  and the remainder are supported only by
the credit of the instrumentality, which may or may not include the right of the
issuer to borrow from the Treasury.

BANK OBLIGATIONS
These are certificates of deposit,  bankers'  acceptances,  and other short-term
debt  obligations.   Certificates  of  deposit  are  short-term  obligations  of
commercial  banks.  A bankers'  acceptance is a time draft drawn on a commercial
bank  by  a  borrower,  usually  in  connection  with  international  commercial
transactions. Certificates of deposit may have fixed or variable rates.

The Portfolios  will not invest in any debt security issued by a commercial bank
unless (i) the bank has total assets of at least $1 billion,  or the  equivalent
in other  currencies,  or, in the case of domestic banks which do not have total
assets of at least $1 billion,  the  aggregate  investment  made in any one such
bank is limited to  $100,000  and the  principal  amount of such  investment  is
insured in full by the Federal Deposit Insurance  Corporation,  (ii) in the case
of U.S. banks, it is a member of the Federal Deposit Insurance Corporation,  and
(iii) in the case of foreign  banks,  the  security  is, in the  opinion of Fred
Alger Management, Inc. ("Alger Management") the Fund's investment manager, of an
investment quality comparable to other debt securities which may be purchased by
the  Portfolios.  These  limitations  do not prohibit  investments in securities
issued by foreign  branches of U.S.  banks,  provided  such U.S.  banks meet the
foregoing requirements.

FOREIGN BANK OBLIGATIONS
Investments by the  Portfolios in foreign bank  obligations  and  obligations of
foreign  branches of domestic banks present certain risks,  including the impact
of future  political  and  economic  developments,  the possible  imposition  of
withholding taxes on interest income, the possible seizure or nationalization of
foreign  deposits,  the possible  establishment of exchange  controls and/or the
addition of other foreign governmental  restrictions that might affect adversely
the payment of principal and interest on these obligations.  In addition,  there
may be less  publicly  available and reliable  information  about a foreign bank
than about domestic banks owing to different accounting, auditing, reporting and
recordkeeping standards. In view of these risks, Alger Management will carefully
evaluate these investments on a case-by-case basis.

SHORT-TERM CORPORATE DEBT SECURITIES
These are outstanding  nonconvertible corporate debt securities (e.g., bonds and
debentures)  which have one year or less remaining to maturity.  Corporate notes
may have fixed, variable, or floating rates.

COMMERCIAL PAPER
These are  short-term  promissory  notes  issued by  corporations  primarily  to
finance short-term credit needs.

VARIABLE RATE MASTER DEMAND NOTES
These are unsecured instruments that permit the indebtedness  thereunder to vary
and provide for periodic  adjustments in the interest rate.  Because these notes
are direct lending  arrangements  between the Portfolio and the issuer, they are
not normally  traded.  Although no active  secondary  market may exist for these
notes, the Portfolio may demand payment of principal and accrued interest at any
time or may resell the note to a third party.  While the notes are not typically
rated by credit  rating  agencies,  issuers of variable rate master demand notes
must satisfy Alger  Management  that the same criteria for issuers of commercial
paper are met. In addition,  when purchasing  variable rate master demand notes,
Alger Management will consider the earning power, cash flows and other liquidity
ratios of 

                                      -2-


<PAGE>
the issuers of the notes and will  continuously  monitor their financial  status
and ability to meet payment on demand. In the event an issuer of a variable rate
master  demand note were to default on its payment  obligations,  the  Portfolio
might be unable to dispose of the note  because  of the  absence of a  secondary
market and could, for this or other reasons,  suffer a loss to the extent of the
default.

REPURCHASE AGREEMENTS
Under the terms of a  repurchase  agreement,  a Portfolio  would  acquire a high
quality money market  instrument for a relatively short period (usually not more
than one week)  subject to an obligation  of the seller to  repurchase,  and the
Portfolio  to resell,  the  instrument  at an agreed  price  (including  accrued
interest) and time, thereby determining the yield during the Portfolio's holding
period.  Repurchase  agreements  may  be  seen  to be  loans  by  the  Portfolio
collateralized by the underlying instrument. This arrangement results in a fixed
rate of return that is not subject to market fluctuations during the Portfolio's
holding  period  and  not  necessarily  related  to the  rate of  return  on the
underlying instrument. The value of the underlying securities, including accrued
interest,  will be at  least  equal  at all  times to the  total  amount  of the
repurchase  obligation,  including interest. A Portfolio bears a risk of loss in
the  event  that the  other  party to a  repurchase  agreement  defaults  on its
obligations  and the Portfolio is delayed in or prevented  from  exercising  its
rights to dispose of the collateral securities, including the risk of a possible
decline in the value of the underlying securities during the period in which the
Portfolio  seeks  to  assert  these  rights,  the  risk  of  incurring  expenses
associated with asserting these rights and the risk of losing all or part of the
income from the agreement. Alger Management, acting under the supervision of the
Fund's  Board of  Trustees,  reviews  the credit  worthiness  of those banks and
dealers with which the Portfolios  enter into repurchase  agreements to evaluate
these risks and monitors on an ongoing basis the value of the securities subject
to repurchase  agreements to ensure that the value is maintained at the required
level.

REVERSE REPURCHASE AGREEMENTS (ALGER MONEY
MARKET PORTFOLIO AND ALGER BALANCED PORTFOLIO)
Reverse repurchase agreements are the same as repurchase agreements except that,
in this instance,  the Portfolio would assume the role of seller/borrower in the
transaction.  Each Portfolio will maintain  segregated  accounts with the Fund's
custodian  consisting of cash or liquid  securities  that at all times are in an
amount  equal  to its  obligations  under  reverse  repurchase  agreements.  The
Portfolios  will invest the proceeds in money market  instruments  or repurchase
agreements  maturing  not later than the  expiration  of the reverse  repurchase
agreement.  Reverse repurchase agreements involve the risk that the market value
of the securities sold by a Portfolio may decline below the repurchase  price of
the  securities.  Under the  Investment  Company  Act of 1940,  as amended  (the
"Act"),  reverse  repurchase  agreements  may be  considered  borrowings  by the
seller;  accordingly,  the  Portfolio  will  limit its  investments  in  reverse
repurchase  agreements  and other  borrowings  to no more than  one-third of its
total assets.


   
FIRM COMMITMENT AGREEMENTS AND
WHEN-ISSUED PURCHASES
Firm commitment agreements and "when-issued"  purchases call for the purchase of
securities at an agreed price on a specified  future date and would be used, for
example,  when a  decline  in the  yield  of  securities  of a given  issuer  is
anticipated  and a  more  advantageous  yield  may  be  obtained  by  committing
currently  to  purchase  securities  to be  issued  later.  When  the  Portfolio
purchases a security under a firm commitment agreement or on a when-issued basis
it assumes the risk of any decline in value of the  security  occurring  between
the  date  of  the  agreement  or  purchase  and  the  settlement  date  of  the
transaction.  The  Portfolio  will not use  these  transactions  for  leveraging
purposes and, accordingly, will segregate cash or liquid securities in an amount
sufficient at all times to meet its purchase obligations under these agreements.
    


WARRANTS AND RIGHTS
Each  Portfolio  may  invest in  warrants  and  rights.  A warrant  is a type of
security that entitles the holder to buy a proportionate  amount of common stock
at a  specified  price,  usually  higher  than the  market  price at the time of
issuance,  for a period of years or to perpetuity.  In contrast,  rights,  which
also  represent the right to buy common  shares,  normally  have a  subscription
price lower than the current  market value of the common stock and a life of two
to four  weeks.  Warrants  are freely  transferable  and are traded on the major
securities exchanges.


RESTRICTED SECURITIES
Each Portfolio may invest in restricted  securities  governed by Rule 144A under
the  Securities  Act of 1933. In adopting Rule 144A, the Securities and Exchange
Commission specifically stated that restricted securities traded under Rule 144A
may be treated as liquid for purposes of investment  limitations if the board of

                                      -3-


<PAGE>
trustees  (or the fund's  adviser  acting  subject to the  board's  supervision)
determines  that the  securities  are in fact liquid.  The Board of Trustees has
delegated its  responsibility  to Alger Management to determine the liquidity of
each restricted security purchased pursuant to the Rule, subject to the Board of
Trustees'  oversight  and review.  Examples  of factors  that will be taken into
account in evaluating the liquidity of a Rule 144A  security,  both with respect
to the initial purchase and on an ongoing basis, will include, among others: (1)
the frequency of trades and quotes for the  security;  (2) the number of dealers
willing to  purchase  or sell the  security  and the  number of other  potential
purchasers;  (3) dealer  undertakings to make a market in the security;  and (4)
the nature of the security and the nature of the marketplace  trades (e.g.,  the
time needed to dispose of the security, the method of soliciting offers, and the
mechanics of transfer).  Because  institutional trading in restricted securities
is relatively new, it is not possible to predict how institutional  markets will
develop.  If institutional  trading in restricted  securities were to decline to
limited  levels,  the  liquidity  of the  Fund's  Portfolio  could be  adversely
affected.

SHORT SALES
Each  Portfolio  other than Alger Money  Market  Portfolio  may sell  securities
"short  against  the  box."  While a short  sale is the sale of a  security  the
Portfolio  does not own, it is "against  the box" if at all times when the short
position  is open  the  Portfolio  owns an equal  amount  of the  securities  or
securities  convertible into, or exchangeable without further consideration for,
securities of the same issue as the securities sold short.

LENDING OF PORTFOLIO SECURITIES
Each  Portfolio  may lend  securities  to brokers,  dealers and other  financial
organizations.  The Portfolios will not lend  securities to Alger  Management or
its affiliates.  By lending its securities,  a Portfolio can increase its income
by continuing to receive interest or dividends on the loaned  securities as well
as by either  investing  the cash  collateral  in  short-term  securities  or by
earning income in the form of interest paid by the borrower when U.S. Government
securities  or letters of credit are used as  collateral.  Each  Portfolio  will
adhere to the following  conditions  whenever its securities are loaned: (a) the
Portfolio  must  receive at least 100  percent  cash  collateral  or  equivalent
securities  from the borrower;  (b) the borrower  must increase this  collateral
whenever the market value of the securities  including  accrued interest exceeds
the value of the  collateral;  (c) the  Portfolio  must be able to terminate the
loan at any time;  (d) the  Portfolio  must receive  reasonable  interest on the
loan, as well as any dividends,  interest or other  distributions  on the loaned
securities  and any increase in market  value;  (e) the  Portfolio  may pay only
reasonable  custodian fees in connection with the loan; and (f) voting rights on
the loaned  securities may pass to the borrower;  provided,  however,  that if a
material event adversely  affecting the investment  occurs,  the Fund's Board of
Trustees must terminate the loan and regain the right to vote the securities.  A
Portfolio bears a risk of loss in the event that the other party to a stock loan
transaction  defaults  on its  obligations  and the  Portfolio  is delayed in or
prevented from exercising its rights to dispose of the collateral  including the
risk of a possible decline in the value of the collateral  securities during the
period  in  which  the  Portfolio  seeks to  assert  these  rights,  the risk of
incurring expenses associated with asserting these rights and the risk of losing
all or a part of the income from the transaction.

FOREIGN SECURITIES
Each Portfolio  other than Alger Money Market  Portfolio may invest up to 20% of
the value of its total  assets in foreign  securities  (not  including  American
Depositary  Receipts,  American  Depositary  Shares  or U.S.  dollar-denominated
securities of foreign issuers).  Foreign securities  investments may be affected
by  changes  in  currency  rates or  exchange  control  regulations,  changes in
governmental administration or economic or monetary policy (in the United States
and abroad) or changed circumstances in dealing between nations.  Dividends paid
by foreign  issuers may be subject to  withholding  and other foreign taxes that
may decrease the net return on these  investments  as compared to dividends paid
to the Portfolio by domestic corporations.  It should be noted that there may be
less publicly  available  information  about foreign issuers than about domestic
issuers, and foreign issuers are not subject to uniform accounting, auditing and
financial reporting  standards and requirements  comparable to those of domestic
issuers.  Securities  of some foreign  issuers are less liquid and more volatile
than securities of comparable domestic issuers and foreign brokerage commissions
are generally higher than in the United States.  Foreign  securities markets may
also be less liquid,  more volatile and less subject to  government  supervision
than those in the United  States.  Investments  in  foreign  countries  could be
affected  by  other  factors  not  present  in  the  United  States,   including
expropriation,  confiscatory  taxation and potential  difficulties  in enforcing
contractual  obligations.  Securities purchased on foreign exchanges may be held
in custody by a foreign branch of a domestic bank.

OPTIONS (ALGER CAPITAL APPRECIATION PORTFOLIO)
A call  option on a security  is a contract  that gives the holder of the option
the right,  in return for a premium paid, to buy from the writer (seller) of the
call option the security  underlying the option at a specified exercise price at
any time  during the term of the  option.  The writer of the call option has the
obligation  upon exercise of the option to deliver the underlying  security upon
payment  of the  exercise  price  during the  option  period.  A put option on a
security is a contract that, in return for the premium,  gives the holder of the
option the right to sell to the writer  (seller)  the  underlying  security at a
specified  price  during  the term of the  option.  The  writer of the put,  who
receives the premium,  has the  obligation to buy the  underlying  security upon
exercise at the exercise price during the option period.

A call option on a security is "covered" if the  Portfolio  owns the  underlying
security  covered by the call or has an absolute and immediate  right to acquire
that security  without  additional  cash  consideration  (or for additional cash
consideration  held in a segregated account by its custodian) upon conversion or
exchange  of other  securities  held in its  portfolio.  A call  option  is also
covered if the  Portfolio  holds a call on the same security as the call written
where  the  exercise  price of the call  held is (1)  equal to or less  than the
exercise price of the call written or (2) greater than the exercise price of the
call written if the  difference is  maintained  by the  Portfolio in cash,  U.S.
Government securities or other high grade short-term obligations in a segregated
account held with its  custodian.  A put option is  "covered"  if the  Portfolio
maintains cash or other high grade short-term  obligations with a value equal to
the exercise  price in a segregated  account  held with its  custodian,  or else
holds a put on the same security as the put written where the exercise  price of
the put held is equal to or greater than the exercise price of the put written.

If the  Portfolio  has written an option,  it may  terminate  its  obligation by
effecting a closing purchase transaction.  This is accomplished by purchasing an
option of the same series as the option previously  written.  However,  once the
Portfolio has been assigned an exercise notice,  the Portfolio will be unable to
effect a closing purchase transaction. Similarly, if the Portfolio is the holder
of an  option  it may  liquidate  its  position  by  effecting  a  closing  sale
transaction. This is accomplished by selling an option of the same series as the
option  previously  purchased.  There can be no assurance  that either a closing
purchase or sale transaction can be effected when the Portfolio so desires.

The Portfolio  will realize a profit from a closing  transaction if the price of
the transaction is less than the premium  received from writing the option or is
more than the premium paid to purchase the option;  the Portfolio will realize a
loss from a closing transaction if the price of the transaction is less than the
premium paid to purchase the option.  Since call option prices generally reflect
increases in the price of the underlying  security,  any loss resulting from the
repurchase of a call option may also be wholly or partially offset by unrealized
appreciation of the underlying  security.  Other principal factors affecting the
market  value of a put or a call  option  include  supply and  demand,  interest
rates, the current market price and price volatility of the underlying  security
and the time remaining until the expiration date.

An option  position  may be closed  out only on an  exchange  which  provides  a
secondary  market for an option of the same series.  Although the Portfolio will
generally  purchase or write only those options for which there appears to be an
active secondary market, there is no assurance that a liquid secondary market on
an exchange will exist for any particular  option. In such event it might not be
possible to effect  closing  transactions  in  particular  options,  so that the
Portfolio  would have to exercise  its option in order to realize any profit and
would incur  brokerage  commissions  upon the  exercise of the  options.  If the
Portfolio,  as a  covered  call  option  writer,  is  unable to effect a closing
purchase  transaction  in a  secondary  market,  it will not be able to sell the
underlying  security  until the option  expires or it  delivers  the  underlying
security upon exercise or otherwise covers the position.

In addition to options on  securities,  the Portfolio may also purchase and sell
call and put options on securities  indexes.  A stock index reflects in a single
number the market value of many different  stocks.  Relative values are assigned
to the stocks included in an index and the index  fluctuates with changes in the
market values of the stocks.  The options give the holder the right to receive a
cash  settlement  during the term of the option based on the difference  between
the exercise  price and the value of the index.  By writing a put or call option
on a securities  index,  the Portfolio is  obligated,  in return for the premium
received, to make delivery of this amount. The Portfolio may offset its position
in  stock  index  options  prior  to  expiration  by  entering  into  a  closing
transaction on an exchange or it may let the option expire unexercised.

Use of  options  on  securities  indexes  entails  the risk that  trading in the
options may be interrupted if trading in

                                      -5-


<PAGE>
certain securities included in the index is interrupted.  The Portfolio will not
purchase   these  options   unless  Alger   Management  is  satisfied  with  the
development, depth and liquidity of the market and Alger Management believes the
options can be closed out.

Price movements in the Portfolio's  securities may not correlate  precisely with
movements in the level of an index and, therefore, the use of options on indexes
cannot  serve as a complete  hedge and will depend,  in part,  on the ability of
Alger  Management to predict  correctly  movements in the direction of the stock
market  generally or of a particular  industry.  Because  options on  securities
indexes require  settlement in cash, Alger Management may be forced to liquidate
portfolio securities to meet settlement obligations.

The  Portfolio  has qualified and intends to continue to qualify as a "Regulated
Investment  Company" under the Internal  Revenue Code. One  requirement for such
qualification  is that the  Portfolio  must  derive  less  than 30% of its gross
income from gains from the sale or other disposition of securities held for less
than three  months.  Therefore,  the  Portfolio may be limited in its ability to
engage in options transactions.

Although Alger Management will attempt to take appropriate  measures to minimize
the risks relating to the Portfolio's writing of put and call options, there can
be no assurance that the Portfolio will succeed in any option-writing program it
undertakes.

STOCK INDEX FUTURES AND OPTIONS ON STOCK
INDEX FUTURES (ALGER CAPITAL APPRECIATION 
PORTFOLIO)
Futures are generally  bought and sold on the  commodities  exchanges where they
are listed with payment of initial and variation  margin as described below. The
sale of a  futures  contract  creates a firm  obligation  by the  Portfolio,  as
seller,  to deliver to the buyer the net cash amount  called for in the contract
at a specific  future time. Put options on futures might be purchased to protect
against  declines in the market values of securities  occasioned by a decline in
stock prices and  securities  index futures  might be sold to protect  against a
general  decline in the value of securities of the type that comprise the index.
Options on futures contracts are similar to options on securities except that an
option on a futures  contract  gives the  purchaser  the right in return for the
premium paid to assume a position in a futures contract and obligates the seller
to deliver such position.  

A stock index future obligates the seller to deliver (and the purchaser to take)
an amount of cash equal to a specific dollar amount times the difference between
the value of a specific  stock index at the close of the last trading day of the
contract and the price at which the agreement is made.  No physical  delivery of
the underlying  stocks in the index is made.  With respect to stock indexes that
are permitted  investments,  the Portfolio  intends to purchase and sell futures
contracts  on the stock  index  for  which it can  obtain  the best  price  with
considerations  also given to  liquidity.  While  incidental  to its  securities
activities, the Portfolio may use index futures as a substitute for a comparable
market position in the underlying securities.  

The risk of imperfect  correlation increases as the composition of the Portfolio
varies from the  composition of the stock index.  In an effort to compensate for
the  imperfect  correlation  of movements in the price of the  securities  being
hedged and movements in the price of the stock index futures,  the Portfolio may
buy or sell stock index  futures  contracts in a greater or lesser dollar amount
than  the  dollar  amount  of the  securities  being  hedged  if the  historical
volatility  of the stock index futures has been less or greater than that of the
securities.  Such "over  hedging" or "under  hedging" may  adversely  affect the
Portfolio's  net investment  results if market  movements are not as anticipated
when the hedge is established.  

An option on a stock  index  futures  contract,  as  contrasted  with the direct
investment in such a contract,  gives the purchaser the right, in return for the
premium  paid,  to assume a position  in a stock  index  futures  contract  at a
specified exercise price at any time prior to the expiration date of the option.
The Portfolio will sell options on stock index futures contracts only as part of
closing purchase  transactions to terminate its options positions.  No assurance
can be given that such closing  transactions  can be effected or that there will
be correlation between price movements in the options on stock index futures and
price  movements  in the  Portfolio's  securities  which are the  subject of the
hedge. In addition,  the Portfolio's purchase of such options will be based upon
predictions as to anticipated market trends, which could prove to be inaccurate.

The Portfolio's use of stock index futures and options thereon will in all cases
be consistent  with  applicable  regulatory  requirements  and in particular the
rules and regulations of the Commodity  Futures  Trading  Commission and will be
entered into only for bona fide  hedging,  risk  management  or other  portfolio
management  purposes.  Typically,  maintaining a futures  contract or selling an
option thereon  requires the Portfolio to deposit with a financial  intermediary
as security  for its  obligations  an amount of cash or other  specified  assets
(initial  margin)  which  initially is typically 1% to 10% of the face amount of
the  contract  (but may be higher  in some  circumstances).  Additional  cash or
assets (variation margin) may be required to be deposited  thereafter 

                                      -6-


<PAGE>
on a daily basis as the mark to market  value of the  contract  fluctuates.  The
purchase of an option on stock index futures  involves  payment of a premium for
the option without any further  obligation on the part of the Portfolio.  If the
Portfolio exercises an option on a futures contract it will be obligated to post
initial margin (and  potential  subsequent  variation  margin) for the resulting
futures  position  just as it would  for any  position.  Futures  contracts  and
options thereon are generally settled by entering into an offsetting transaction
but  there  can be no  assurance  that  the  position  can be  offset  prior  to
settlement at an advantageous price, nor that delivery will occur.

The Portfolio  will not enter into a futures  contract or related option (except
for closing transactions) if, immediately  thereafter,  the sum of the amount of
its initial  margin and premiums on open futures  contracts and options  thereon
would  exceed 5% of the  Portfolio's  total  assets  (taken at  current  value);
however,  in the  case of an  option  that is  in-the-money  at the  time of the
purchase,  the  in-the-money  amount  may  be  excluded  in  calculating  the 5%
limitation.

INVESTMENT RESTRICTIONS
The investment restrictions numbered 1 through 13 below have been adopted by the
Fund with respect to each of the Portfolios as fundamental  policies.  Under the
Act, a  "fundamental"  policy may not be changed without the vote of a "majority
of the outstanding  voting  securities" of the Fund, which is defined in the Act
as the lesser of (a) 67 percent or more of the shares  present at a Fund meeting
if the holders of more than 50 percent of the outstanding shares of the Fund are
present or represented  by proxy or (b) more than 50 percent of the  outstanding
shares. A fundamental policy affecting a particular Portfolio may not be changed
without  the vote of a majority  of the  outstanding  voting  securities  of the
affected Portfolio. Investment restrictions 14 through 19 may be changed by vote
of a majority of the Fund's Board of Trustees at any time.

The investment policies adopted by the Fund prohibit each Portfolio from:

1.  Purchasing  the  securities  of  any  issuer,  other  than  U.S.  Government
securities,  if as a  result  more  than  five  percent  of  the  value  of  the
Portfolio's  total  assets  would be invested in the  securities  of the issuer,
except that up to 25 percent of the value of the  Portfolio's  (other than Alger
Money Market  Portfolio's)  total assets may be invested  without regard to this
limitation.

2. Purchasing more than 10 percent of the voting securities of any one issuer or
more than 10  percent of the  securities  of any class of any one  issuer.  This
limitation shall not apply to investments in U.S. Government securities.

3. Selling securities short or purchasing  securities on margin, except that the
Portfolio  may obtain any  short-term  credit  necessary  for the  clearance  of
purchases  and  sales of  securities.  These  restrictions  shall  not  apply to
transactions involving selling securities "short against the box."

4. Borrowing  money,  except that (a) all Portfolios may borrow for temporary or
emergency  purposes  including  the meeting of  redemption  requests  that might
otherwise  require the  untimely  disposition  of  securities,  in an amount not
exceeding 10 percent of the value of the Portfolio's total assets (including the
amount borrowed)  valued at the lesser of cost or market,  less liabilities (not
including  the amount  borrowed) at the time the  borrowing  is made;  (b) Alger
Money Market  Portfolio and Alger Balanced  Portfolio may engage in transactions
in reverse repurchase  agreements;  and (c) Alger Capital Appreciation Portfolio
may borrow from banks for  investment  purposes as set forth in the  Prospectus.
Whenever  borrowings  described  in (a) exceed five  percent of the value of the
Portfolio's   total  assets,   the  Portfolio   will  not  make  any  additional
investments.  Immediately  after any  borrowing,  including  reverse  repurchase
agreements,  the  Portfolio  will maintain  asset  coverage of not less than 300
percent with respect to all borrowings.

5. Pledging,  hypothecating,  mortgaging or otherwise  encumbering  more than 10
percent of the value of the  Portfolio's  total assets except in connection with
borrowings  as  noted in 4(c)  above.  These  restrictions  shall  not  apply to
transactions   involving  reverse  repurchase  agreements  or  the  purchase  of
securities subject to firm commitment agreements or on a when-issued basis.

6. Issuing senior  securities,  except in connection with  borrowings  permitted
under restriction 4.

7. Underwriting the securities of other issuers, except insofar as the Portfolio
may be deemed to be an underwriter under the Securities Act of 1933, as amended,
by virtue of disposing of portfolio securities.

8. Making loans to others, except through purchasing qualified debt obligations,
lending portfolio securities or entering into repurchase agreements.

9. Investing in securities of other investment companies,  except as they may be
acquired  as part of a merger,  

                                      -7-


<PAGE>
consolidation, reorganization, acquisition of assets or offer of exchange.

10. Purchasing any securities that would cause more than 25 percent of the value
of the  Portfolio's  total  assets to be invested in the  securities  of issuers
conducting their principal  business  activities in the same industry;  provided
that (a) there shall be no limit on the purchase of U.S. Government  securities,
and (b) there shall be no limit on the purchase by Alger Money Market  Portfolio
of  obligations  issued  by  bank  and  thrift  institutions  described  in  the
Prospectus and this Statement of Additional Information.

11. Investing in commodities,  except that Alger Capital Appreciation  Portfolio
may purchase or sell stock index futures  contracts and related  options thereon
if,  thereafter,  no more than 5 percent  of its total  assets are  invested  in
margin and premiums.

12.  Investing  more than 10 percent  (15  percent in the case of Alger  Capital
Appreciation  Portfolio) of its net assets in  securities  which are illiquid by
virtue  of legal or  contractual  restrictions  on resale  or the  absence  of a
readily  available  market.  However,   securities  with  legal  or  contractual
restrictions on resale may be purchased by Alger Money Market  Portfolio if they
are determined to be liquid,  and such purchases  would not be subject to the 10
percent limit stated above.  The Board of Trustees will in good faith  determine
the  specific  types of  securities  deemed to be  liquid  and the value of such
securities held in Alger Money Market  Portfolio.  Alger Money Market  Portfolio
will not purchase  time deposits  maturing in more than seven  calendar days and
will  limit to no more than 10 percent  of its  assets  its  investment  in time
deposits  maturing  in  excess of two  business  days,  together  with all other
illiquid securities.

13.  Purchasing  or selling  real  estate or real estate  limited  partnerships,
except that the  Portfolio  may  purchase  and sell  securities  secured by real
estate,  mortgages  or  interests  therein  and  securities  that are  issued by
companies that invest or deal in real estate.

14. Writing or selling puts, calls, straddles,  spreads or combinations thereof,
except that Alger  Capital  Appreciation  Portfolio  may buy and sell (write) in
options.

15. Investing in oil, gas or other mineral exploration or development  programs,
except that the Portfolio may invest in the  securities of companies that invest
in or sponsor those programs.

16. Purchasing any security if, as a result,  the Portfolio would then have more
than  five  percent  of its total  assets  invested  in  securities  of  issuers
(including  predecessors)  that have been in continual  operation  for less than
three years.  This limitation shall not apply to investments in U.S.  Government
securities.

17. Making investments for the purpose of exercising control or management.

18. Investing in warrants,  except that the Portfolio may invest in warrants if,
as a result,  the investments  (valued at the lower of cost or market) would not
exceed five  percent of the value of the  Portfolio's  net assets,  of which not
more than two percent of the  Portfolio's net assets may be invested in warrants
not listed on a recognized  domestic stock  exchange.  Warrants  acquired by the
Portfolio as part of a unit or attached to securities at the time of acquisition
are not subject to this limitation.

19. Purchasing or retaining the securities of any issuer if, to the knowledge of
the  Fund,  any of the  officers,  directors  or  trustees  of the Fund or Alger
Management  individually owns more than .5 percent of the outstanding securities
of the issuer and together they own  beneficially  more than five percent of the
securities.

   
Shares of Alger Growth Portfolio, Alger Small Capitalization Portfolio and Alger
MidCap Growth  Portfolio are  registered  for sale in Germany.  As long as Alger
Growth Portfolio,  Alger Small Capitalization  Portfolio and Alger MidCap Growth
Portfolio are  registered  in Germany,  these  Portfolios  may not without prior
approval of their shareholders:
    

   a.Invest  in the  securities  of any other  domestic  or  foreign  investment
     company or investment  fund except in  connection  with a plan of merger or
     consolidation  with or acquisition of substantially  all the assets of such
     other investment company or investment fund;

   b.Purchase  or sell real  estate or any  interest  therein,  and real  estate
     mortgage  loans,  except that the  Portfolios  may invest in  securities of
     corporate or  governmental  entities  secured by real estate or  marketable
     interests therein or securities issued by companies (other than real estate
     limited partnerships,  real estate investment trusts and real estate funds)
     that invest in real estate or interests therein;

   c.Borrow  money,  except for  temporary  or  emergency  (but not  leveraging)
     purposes including the meeting of redemption  requests that might otherwise
     require the untimely disposition of securities,  in an amount not exceeding
     10 percent of the value of the  Portfolio's  total  assets  (including  the
     amount borrowed)  valued at the lesser of cost or market,  

                                      -8-

<PAGE>
     less  liabilities  (not  including  the  amount  borrowed)  at the time the
     borrowing is made;

   d. Pledge, hypothecate, mortgage or otherwise encumber their assets except to
      secure indebtedness permitted under section c.;

   e. Purchase securities on margin or make short sales; or;

   f. Redeem their securities in kind.

These Portfolios will comply with the more restrictive  policies required by the
German regulatory  authorities,  as stated above, as long as such Portfolios are
registered in Germany.

Except  in the  case of the 300  percent  limitation  set  forth  in  Investment
Restriction  No. 4 and as may be stated  otherwise,  the percentage  limitations
contained  in the  foregoing  restrictions  and in the Fund's  other  investment
policies  apply  at the  time  of the  purchase  of the  securities  and a later
increase or decrease in percentage  resulting from a change in the values of the
securities  or in the amount of the  Portfolio's  assets will not  constitute  a
violation of the restriction.

PORTFOLIO TRANSACTIONS
Decisions  to buy and sell  securities  and other  financial  instruments  for a
Portfolio are made by Alger  Management,  which also is responsible  for placing
these  transactions,  subject  to the  overall  review  of the  Fund's  Board of
Trustees.  Although  investment  requirements  for each  Portfolio  are reviewed
independently  from those of the other accounts  managed by Alger Management and
those of the other  Portfolios,  investments of the type the Portfolios may make
may also be made by these other accounts or Portfolios. When a Portfolio and one
or more other Portfolios or accounts managed by Alger Management are prepared to
invest  in,  or desire to  dispose  of,  the same  security  or other  financial
instrument,  available  investments or opportunities for sales will be allocated
in a manner believed by Alger Management to be equitable to each. In some cases,
this procedure may affect adversely the price paid or received by a Portfolio or
the size of the position obtained or disposed of by a Portfolio. 

Transactions  in equity  securities  are in many cases  effected  on U. S. stock
exchanges and involve the payment of negotiated brokerage commissions.  There is
generally  no  stated  commission  in  the  case  of  securities  traded  in the
over-the-counter markets, but the prices of those securities include undisclosed
commissions  or mark-ups.  Purchases and sales of money market  instruments  and
debt  securities  usually  are  principal  transactions.  These  securities  are
normally  purchased  directly from the issuer or from an  underwriter  or market
maker for the  securities.  The cost of securities  purchased from  underwriters
includes  an  underwriting  commission  or  concession  and the  prices at which
securities are purchased from and sold to dealers include a dealer's  mark-up or
mark-down. U. S. Government securities are generally purchased from underwriters
or dealers,  although  certain  newly-issued U. S. Government  securities may be
purchased  directly  from the U. S.  Treasury  or from  the  issuing  agency  or
instrumentality.

To the extent consistent with applicable provisions of the Act and the rules and
exemptions  adopted  by the  Securities  and  Exchange  Commission  (the  "SEC")
thereunder,  as well as  other  regulatory  requirements,  the  Fund's  Board of
Trustees has determined  that portfolio  transactions  will be executed  through
Fred Alger & Company,  Incorporated  ("Alger Inc.") if, in the judgment of Alger
Management,  the use of Alger Inc. is likely to result in price and execution at
least  as  favorable  as  those of other  qualified  broker-dealers  and if,  in
particular  transactions,  Alger  Inc.  charges  the  Portfolio  involved a rate
consistent  with that charged to  comparable  unaffiliated  customers in similar
transactions.  Such  transactions will be fair and reasonable to the Portfolio's
shareholders.  Over-the-counter purchases and sales are transacted directly with
principal  market  makers  except  in those  cases in which  better  prices  and
executions may be obtained  elsewhere.  Principal  transactions  are not entered
into with  affiliates of the Fund except  pursuant to exemptive  rules or orders
adopted by the SEC.

In selecting brokers or dealers to execute portfolio transactions on behalf of a
Portfolio, Alger Management seeks the best overall terms available. In assessing
the best overall terms  available for any  transaction,  Alger  Management  will
consider the factors it deems  relevant,  including the breadth of the market in
the  investment,  the  price of the  investment,  the  financial  condition  and
execution  capability  of the  broker or dealer  and the  reasonableness  of the
commission,  if any, for the specific  transaction and on a continuing basis. In
addition,  Alger  Management is  authorized,  in selecting  parties to execute a
particular  transaction and in evaluating the best overall terms  available,  to
consider  the  brokerage  and research  services,  as those terms are defined in
section 28(e) of the Securities  Exchange Act of 1934, provided to the Portfolio
involved, the other Portfolios and/or other accounts over which Alger Management
or its affiliates exercise investment  discretion.  The Fund will consider sales
of its  shares  as a  factor  in the  selection  of  broker-dealers  to  execute
over-the-counter  transactions,  subject to the  requirements  of 

                                      -9-

best price and execution.  Alger Management's fees under its agreements with the
Portfolios  are not reduced by reason of its  receiving  brokerage  and research
service.  The Fund's Board of Trustees will periodically  review the commissions
paid by the Portfolios to determine if the commissions paid over  representative
periods  of time are  reasonable  in  relation  to the  benefits  inuring to the
Portfolios.  During the fiscal years ended October 31, 1995, 1996, and 1997, the
Fund paid an aggregate of  approximately  $799,446,  $1,554,261  and  $2,875,727
respectively,  in  commissions  to  Alger  Inc.  in  connection  with  portfolio
transactions.  The  commissions  paid to Alger Inc. during the fiscal year ended
October 31, 1997 constituted 98% of the aggregate brokerage  commissions paid by
the Fund;  during that year, 97% of the aggregate  dollar amount of transactions
by the Fund involving the payment of brokerage  commissions was effected through
Alger Inc.  Alger Inc. does not engage in principal  transactions  with the Fund
and,  accordingly,  received  no  compensation  in  connection  with  securities
purchased  or  sold in that  manner,  which  include  securities  traded  in the
over-the-counter markets, money market investments and most debt securities.

NET ASSET VALUE
The  Prospectus  discusses the time at which the net asset values of the classes
of each Portfolio are determined for purposes of sales and redemptions.  The New
York Stock Exchange  ("NYSE") is currently  open on each Monday through  Friday,
except (i) New Year's Day,  Martin Luther King,  Jr. Day,  Presidents'  Day (the
third Monday in February),  Good Friday,  Memorial Day (the last Monday in May),
Independence  Day, Labor Day (the first Monday in September),  Thanksgiving  Day
(the fourth  Thursday in  November)  and  Christmas  Day and (ii) the  preceding
Friday when any one of those  holidays  falls on a Saturday,  or the  subsequent
Monday when any one of those  holidays  falls on a Sunday.  The  following  is a
description  of the  procedures  used by the  Fund in  valuing  the  Portfolios'
assets. 
    

The assets of the  Portfolios  other  than  Alger  Money  Market  Portfolio  are
generally valued on the basis of market  quotations.  Securities whose principal
market is on an  exchange  or in the  over-the-counter  market are valued at the
last  reported  sales price or, in the absence of  reported  sales,  at the mean
between  the bid and asked  price or, in the  absence  of a recent  bid or asked
price,  the  equivalent  as obtained from one or more of the major market makers
for the securities to be valued.  Bonds and other fixed income securities may be
valued on the basis of prices  provided  by a pricing  service  when the  Fund's
Board of Trustees  believes  that these prices  reflect the fair market value of
the  securities.  Other  investments  and  other  assets,  including  restricted
securities and securities for which market quotations are not readily available,
are valued at fair  value  under  procedures  approved  by the  Fund's  Board of
Trustees. Short-term securities with maturities of 60 days or less are valued at
amortized cost, as described below,  which  constitutes fair value as determined
by the Fund's Board of Trustees.

The valuation of the securities held by Alger Money Market Portfolio, as well as
money market  instruments  with  maturities of 60 days or less held by the other
Portfolios,  is based on their  amortized  cost which does not take into account
unrealized capital gains or losses.  Amortized cost valuation involves initially
valuing  an  instrument  at  its  cost  and   thereafter   assuming  a  constant
amortization to maturity of any discount or premium, regardless of the impact of
fluctuating interest rates on the market value of the instrument.  Although this
method  provides  certainty in valuation,  it may result in periods during which
value,  as  determined  by amortized  cost,  is higher or lower than the price a
Portfolio would receive if it sold the instrument.

Alger Money Market  Portfolio's  use of the amortized cost method of valuing its
securities  is  permitted  by a rule  adopted by the SEC.  Under this rule,  the
Portfolio must maintain a dollar-weighted  average portfolio maturity of 90 days
or less, purchase only instruments having remaining  maturities of less than 397
days, as determined in accordance  with the  provisions of the rule,  and invest
only in securities determined by Alger Management,  acting under the supervision
of the Fund's  Board of Trustees,  to be of high  quality  with  minimal  credit
risks.

Pursuant  to the  rule,  the  Fund's  Board of  Trustees  also  has  established
procedures designed to stabilize, to the extent reasonably possible, Alger Money
Market  Portfolio's  price per share as  computed  for the  purpose of sales and
redemptions  at  $1.00.  These  procedures  include  review  of the  Portfolio's
holdings  by the  Fund's  Board  of  Trustees,  at such  intervals  as it  deems
appropriate,  to determine whether the Portfolio's net asset value calculated by
using available market quotations or market equivalents  deviates from $1.00 per
share based on amortized cost.

The rule also provides that the extent of any deviation  between the Portfolio's
net asset value based on available market  quotations or market  equivalents and
$1.00 per share net asset value based on amortized  cost must be examined by the
Fund's Board of Trustees.  In the event the Fund's Board of Trustees  determines
that a 

                                      -10-


<PAGE>
deviation exists that may result in material dilution or other unfair results to
investors  or existing  shareholders,  pursuant to the rule the Fund's  Board of
Trustees must cause the Portfolio to take such  corrective  action as the Fund's
Board of Trustees  regards as  necessary  and  appropriate,  including:  selling
portfolio instruments prior to maturity to realize capital gains or losses or to
shorten   average   portfolio   maturity,   withholding   dividends   or  paying
distributions  from  capital  or  capital  gains,  redeeming  shares  in kind or
establishing  net asset value per share by using  available  market  quotations.

PURCHASES 
Shares  of  the  Portfolios  are  offered  continuously  by  the  Fund  and  are
distributed on a best efforts basis by Alger Inc. as principal  underwriter  for
the Fund pursuant to distribution  agreements (the  "Distribution  Agreements").
Under the  Distribution  Agreements,  Alger  Inc.  bears all  selling  expenses,
including the costs of advertising and of printing prospectuses and distributing
them to prospective shareholders.

DISTRIBUTION PLANS
As stated in the Prospectus,  in connection with the distribution  activities of
Alger Inc.  in respect of the Fund's  Class B and Class C Shares,  respectively,
the Fund has adopted two Distribution Plans (the "Plans") pursuant to Rule 12b-1
under the Act, one for each class.

Reimbursable  distribution  expenses  covered under the Class B Plan may include
payments made to and expenses of persons who are engaged in, or provide  support
services in connection  with, the  distribution of the class's  shares,  such as
answering routine telephone inquiries for prospective shareholders; compensation
in the form of sales concessions and continuing  compensation paid to securities
dealers  whose  customers  hold  shares  of  the  class;  costs  related  to the
formulation  and   implementation  of  marketing  and  promotional   activities,
including direct mail promotions and television,  radio, newspaper, magazine and
other mass media  advertising;  costs of printing and distributing  prospectuses
and  reports  to  prospective  shareholders  of the  class;  costs  involved  in
preparing,  printing and distributing  sales literature for the class; and costs
involved in obtaining whatever information, analyses and reports with respect to
marketing and promotional  activities on behalf of the class that the Fund deems
advisable.

   
Historically,  distribution  expenses  incurred by Alger Inc.  have exceeded the
Class B assets available for  reimbursement  under the Plan; it is possible that
in the future the converse may be true. Distribution expenses incurred in a year
in respect of Class B Shares of a  Portfolio  in excess of  contingent  deferred
sales charges ("CDSCs") received by Alger Inc. relating to redemptions of shares
of the class  during that year and .75 percent of the class'  average  daily net
assets  may be carried  forward  and sought to be  reimbursed  in future  years.
Interest at the  prevailing  broker  loan rate may be charged to the  applicable
Portfolio's  Class B Shares on any expenses  carried  forward and those expenses
and interest will be reflected as current expenses on the Portfolio's  statement
of operations for the year in which the amounts become  accounting  liabilities,
which is  anticipated  to be the year in which these amounts are actually  paid.
Although the Fund's  Board of Trustees  may change this policy,  it is currently
anticipated  that  payments  under the Plan in a year will be  applied  first to
distribution  expenses  incurred in that year and then, up to the maximum amount
permitted  under the Plan,  to  previously  incurred but  unreimbursed  expenses
carried forward plus interest thereon.
    

The Plan for Class C Shares pays annually a flat  percentage (up to .75 percent)
of the class's average daily net assets to Alger Inc., regardless of whether the
associated  distribution  expenses incurred are higher or lower than the fee. No
excess  distribution  expense shall be carried forward to subsequent years under
this Plan.  Distribution  services for which Alger Inc. is compensated under the
Class C Plan may  include,  but are not limited to,  organizing  and  conducting
sales  seminars,  advertising  programs,  payment of finders' fees,  printing of
prospectuses and statements of additional information and reports for other than
existing shareholders,  preparation and distribution of advertising material and
sales  literature,   overhead,   supplemental  payments  to  dealers  and  other
institutions  as  asset-based  sales  charges or as payments of  commissions  or
service fees, and the costs of administering the Plan.

Alger Inc. has  acknowledged  that  payments  under the Plans are subject to the
approval of the Fund's Board of Trustees and that no Portfolio is  contractually
obligated to make payments in any amount or at any time,  including  payments in
reimbursement  of Alger Inc. for expenses  and  interest  thereon  incurred in a
prior year.

Under their terms,  the Plans remain in effect from year to year,  provided such
continuation  is approved in each case  annually by vote of the Fund's  Board of
Trustees, including a majority of the Trustees who are not interested persons of
the Fund and who have no direct or indirect  financial interest in the operation
of the Plan  ("Independent  Trustees").  A Plan may not be amended  to  increase
materially  the  amount  to be spent for the  services  provided  by Alger  Inc.
without the approval of shareholders of the applicable  class,  and all material
amendments  of a Plan must be approved by the  Trustees in the manner  described
above.  A Plan may be  termi-

                                      -11-


<PAGE>
   
nated at any time,  without  penalty,  by vote of a majority of the  Independent
Trustees or, with  respect to the Class B or Class C Shares of any  Portfolio to
which  a Plan  relates,  by a vote  of a  majority  of  the  outstanding  voting
securities  of the class,  on not more than thirty days'  written  notice to any
other party to the Plan. If a Plan is terminated, or not renewed with respect to
any one or more Portfolios,  it may continue in effect with respect to the Class
B or Class C Shares of any Portfolio as to which it has not been terminated,  or
has been  renewed.  Alger Inc.  will provide to the Board of Trustees  quarterly
reports  of amounts  expended  under  each Plan and the  purpose  for which such
expenditures  were made. During the fiscal year ended October 31, 1997, the Fund
reimbursed  $8,858,000  to Alger  Inc.  as the  Fund's  underwriter,  under  the
provisions of the Class B Shares' Plan.  Alger Inc.'s  selling  expenses  during
that period  totaled  $13,251,209  which  consisted  of $534,235 in printing and
mailing of  prospectuses  and other sales  literature to prospective  investors;
$1,803,868 in advertising;  $7,689,808 in  compensation to dealers;  $909,071 in
compensation  to sales  personnel;  $224,222 in other  marketing  expenses;  and
$2,090,008 in interest,  carrying or other financing  charges.  If in any month,
the costs  incurred  by Alger Inc.  are in excess of the  distribution  expenses
charged to Class B Shares of a  Portfolio,  the  excess may be carried  forward,
with interest,  and sought to be paid in future periods.  During the fiscal year
ended October 31, 1997,  the Fund paid $1,150 to Alger Inc. under the provisions
of the Class C Shares' plan.

SHAREHOLDER SERVICING AGREEMENT
Payments under the Shareholder  Servicing  Agreement are not tied exclusively to
the  shareholder  servicing  expenses  actually  incurred by Alger Inc.  and the
payments may exceed expenses actually incurred by Alger Inc. The Fund's Board of
Trustees evaluates the  appropriateness of the Shareholder  Servicing  Agreement
and its  payment  terms on a  continuing  basis  and in doing so  considers  all
relevant  factors,  including  expenses  borne by Alger Inc.  and the amounts it
receives under the  Shareholder  Servicing  Agreement.  During the Fund's fiscal
year ended  October 31, 1997,  the Fund paid  approximately  $3,071,000 to Alger
Inc. under the Shareholder Servicing Agreement. 
    

EXPENSES OF THE FUND
Each Portfolio will bear its own expenses. Operating expenses for each Portfolio
generally  consist  of all costs  not  specifically  borne by Alger  Management,
including  investment  management  fees,  fees for  necessary  professional  and
brokerage  services,  costs of regulatory  compliance and costs  associated with
maintaining legal existence and shareholder relations. In addition,  Class B and
Class C of each Portfolio other than Alger Money Market  Portfolio may pay Alger
Inc. for expenses  incurred in  distributing  shares of that class and each such
Portfolio may compensate Alger Inc. for servicing shareholder accounts. Fundwide
expenses not identifiable to any particular portfolio or class will be allocated
in a manner  deemed fair and  equitable by the Board of  Trustees.  From time to
time, Alger Management, in its sole discretion and as it deems appropriate,  may
assume  certain  expenses of one or more of the Portfolios  while  retaining the
ability to be paid by the applicable Portfolio for such amounts prior to the end
of the  fiscal  year.  This will  have the  effect of  lowering  the  applicable
Portfolio's  overall expense ratio and of increasing yield to investors,  or the
converse,  at the time such amounts are assumed or  reimbursed,  as the case may
be. 

   
PURCHASES THROUGH PROCESSING ORGANIZATIONS
When shares are purchased this way, the Processing Organization, rather than its
customer,  may be the  shareholder of record of the shares.  The minimum initial
and subsequent  investments in classes of the  Portfolios for  shareholders  who
invest  through  a  Processing  Organization  will  be  set  by  the  Processing
Organization.  Processing  Organizations  may charge  their  customers  a fee in
connection with services offered to customers. 

TELEPURCHASE PRIVILEGE
The price the  shareholder  will receive will be the price next  computed  after
Alger Shareholder Services,  Inc. (the "Transfer Agent") receives the investment
from the  shareholder's  bank, which is normally one banking day. While there is
no  charge to  shareholders  for this  service,  a fee will be  deducted  from a
shareholder's Fund account in case of insufficient  funds. This privilege may be
terminated at any time without charge or penalty by the  shareholder,  the Fund,
the Transfer Agent or Alger Inc. Class A Share  purchases will remain subject to
the initial sales charge. 

AUTOMATIC INVESTMENT PLAN
While  there  is no  charge  to  shareholders  for this  service,  a fee will be
deducted from a shareholder's Fund account in the case of insufficient  funds. A
shareholder's  Automatic  Investment  Plan may be terminated at any time without
charge or penalty by the shareholder, the Fund, the Transfer Agent or Alger Inc.
Class A Share purchases will remain subject to the initial sales charge.
    

AUTOMATIC EXCHANGE PLAN
There is no charge to shareholders for this service.  A shareholder's  Automatic
Exchange  Plan may be  terminated  at any time without  charge or penalty by the
shareholder,  the  Fund,  the  Transfer  Agent or Alger  Inc.  If the  automatic
exchange amount exceeds the Alger Money Market Portfolio balance,  any remaining
bal-

                                      -12-


<PAGE>
ance  in  Alger  Money  Market  Portfolio  will  be  exchanged.  Shares  held in
certificate form are not eligible for this service. Class A Share purchases will
remain subject to the front-end load.

REDEMPTIONS
The right of redemption of shares of a Portfolio may be suspended or the date of
payment  postponed for more than seven days (a) for any periods during which the
NYSE is closed (other than for customary weekend and holiday closings), (b) when
trading in the markets the  Portfolio  normally  utilizes is  restricted,  or an
emergency,  as defined by the rules and regulations of the SEC,  exists,  making
disposal of the Portfolio's investments or determination of its net asset values
not reasonably practicable or (c) for such other periods as the SEC by order may
permit for protection of the Fund's shareholders.

   
No interest  will accrue on amounts  represented  by  uncashed  distribution  or
redemption checks.
    

CHECK REDEMPTION PRIVILEGE
Unless investors elect otherwise, checks drawn on jointly-owned accounts will be
honored with the signature of either of the joint owners. Shareholders should be
aware that use of the check redemption procedure does not give rise to a banking
relationship  between the  shareholder  and the  Transfer  Agent,  which will be
acting solely as transfer agent for the Portfolio;  nor does it create a banking
relationship  between the shareholder and the Fund. When a check is presented to
the Transfer Agent for payment,  the Transfer  Agent,  as the investor's  agent,
will cause the Fund to redeem a sufficient  number of shares from the investor's
account to cover the amount of the check.

   
Shares for which  stock  certificates  have been  issued may not be  redeemed by
check. An investor's  account with Alger Money Market  Portfolio will be reduced
by any CDSC applicable to any redemption,  including a redemption by check.  The
check redemption privilege may be modified or terminated at any time by the Fund
or by the Transfer Agent.
    

REDEMPTIONS IN KIND
Payment for shares tendered for redemption is ordinarily made in cash.  However,
if the Board of Trustees of the Fund  determines that it would be detrimental to
the best interest of the remaining shareholders of the Portfolio to make payment
of a  redemption  order  wholly  or partly in cash,  the  Portfolio  may pay the
redemption  proceeds  in  whole  or in  part  by a  distribution  "in  kind"  of
securities  from the Portfolio,  in lieu of cash, in conformity  with applicable
rules of the  Securities  and  Exchange  Commission.  The Fund has elected to be
governed by Rule 18f-1 under the Act, pursuant to which a Portfolio is obligated
to redeem  shares  solely in cash up to the lesser of  $250,000 or 1% of the net
assets of the  Portfolio  during any 90-day period for any one  shareholder.  If
shares are redeemed in kind, the redeeming  shareholder might incur brokerage or
other costs in selling the securities for cash. The method of valuing securities
used to make redemptions in kind will be the same as the method the Fund uses to
value its portfolio  securities  and such  valuation will be made as of the time
the redemption price is determined.

   
CERTAIN WAIVERS OF THE CONTINGENT DEFERRED SALES CHARGE
Any CDSC which  otherwise would be imposed on redemptions of Fund shares will be
waived in certain  instances,  including (a)  redemptions  of shares held at the
time  a  shareholder  becomes  disabled  or  dies,  including  the  shares  of a
shareholder  who owns the shares  with his or her spouse as joint  tenants  with
right of survivorship, provided that the redemption is requested within one year
after the death or initial  determination  of  disability,  (b)  redemptions  in
connection  with the following  retirement plan  distributions:  (i) lump-sum or
other  distri-  butions  from a qualified  corporate  or Keogh  retirement  plan
following retirement,  termination of employment, death or disability (or in the
case of a five percent  owner of the employer  maintaining  the plan,  following
attainment  of age  70l/2);  (ii)  required  distributions  from  an  Individual
Retirement  Account  ("IRA")  following  the  attainment  of age 70l/2 or from a
custodial  account under Section 403(b)(7) of the Internal Revenue Code of 1986,
following  the later of  retirement  or  attainment  of age  70l/2;  and (iii) a
tax-free  return  of an  excess  contribution  to an  IRA,  and  (c)  systematic
withdrawal payments. For purposes of the waiver described in (a) above, a person
will be deemed  "disabled" if the person is unable to engage in any  substantial
gainful  activity  by reason of any  medically  determinable  physical or mental
impairment  that can be expected  to result in death or to be of  long-continued
and indefinite duration.

REINSTATEMENT PRIVILEGE
A  shareholder  who has redeemed  shares in the Fund may reinvest all or part of
the redemption  proceeds in the Fund without an initial sales charge and receive
a credit for any CDSC paid on the redemption,  provided the reinvestment is made
within  30 days  after  the  redemption.  This  reinstatement  privilege  may be
exercised only once by a shareholder.  Reinstatement  will not alter any capital
gains  tax  payable  on the  redemption  and a loss may not be  allowed  for tax
purposes.
    

                                      -13-


<PAGE>
SYSTEMATIC WITHDRAWAL PLAN
A  systematic   withdrawal  plan  (the   "Withdrawal   Plan")  is  available  to
shareholders  who own shares of a Portfolio with a value  exceeding  $10,000 and
who wish to receive  specific  amounts of cash  periodically.  Withdrawals of at
least $50 monthly (but no more than one percent of the value of a  shareholder's
shares in the Portfolio)  may be made under the Withdrawal  Plan by redeeming as
many  shares  of the  Portfolio  as may be  necessary  to cover  the  stipulated
withdrawal   payment.   To  the  extent  that  withdrawals   exceed   dividends,
distributions  and appreciation of a shareholder's  investment in the Portfolio,
there  will be a  reduction  in the value of the  shareholder's  investment  and
continued  withdrawal  payments  may reduce  the  shareholder's  investment  and
ultimately  exhaust it.  Withdrawal  payments should not be considered as income
from investment in a Portfolio.

Shareholders  who wish to participate in the Withdrawal  Plan and who hold their
shares in  certificated  form  must  deposit  their  share  certificates  of the
Portfolio from which withdrawals will be made with Alger  Shareholder  Services,
Inc., as agent for Withdrawal Plan members.  All dividends and  distributions on
shares in the Withdrawal Plan are automatically reinvested at net asset value in
additional  shares  of  the  Portfolio  involved.   For  additional  information
regarding the Withdrawal Plan, contact the Fund.

EXCHANGES AND CONVERSIONS
IN GENERAL
One class of shares may not be exchanged  for another  class of shares.  Once an
initial  sales  charge  has been  imposed on a  purchase  of Class A Shares,  no
additional charge is imposed in connection with their exchange.  For example,  a
purchase of Alger Money Market Portfolio shares and subsequent exchange to Class
A Shares of Alger Small Capitalization Portfolio,  Alger Midcap Portfolio, Alger
Growth  Portfolio,  Alger  Balanced  Portfolio  or  Alger  Capital  Appreciation
Portfolio  (each a "Charge  Portfolio")  would  result in the  imposition  of an
initial  sales charge at the time of exchange;  but if the initial  purchase had
been of Class A Shares in a Charge  Portfolio,  an exchange to Class A Shares of
any other Portfolio would not result in an additional  initial sales charge.  No
CDSC is assessed in connection with exchanges at any time. In addition,  no CDSC
is  imposed  on  the  redemption  of  reinvested   dividends  or  capital  gains
distributions  or on  increases  in the net asset value of shares of a Portfolio
above purchase  payments made with respect to that Portfolio during the six-year
holding  period for Class B Shares and the one-year  holding  period for Class C
Shares and certain Class A Shares.

For  purposes of  calculating  the  applicable  holding  periods  for  automatic
conversion of Class B (eight years) and Class C (twelve years) Shares to Class A
Shares,  shares acquired in an exchange are deemed to have been purchased on the
date on which the shares given in exchange were  purchased,  provided,  however,
that if Class B or Class C Shares are exchanged for shares of Alger Money Market
Portfolio,  the period during which the Alger Money Market  Portfolio shares are
held will not be  included  in the holding  period for  purposes of  determining
eligibility for automatic conversion, and the running of the holding period will
recommence  only when those  shares are  reexchanged  for shares of the original
class.

FOR  SHAREHOLDERS  MAINTAINING  AN ACTIVE  ACCOUNT ON OCTOBER 17,  1992.  Shares
acquired in an exchange are deemed to have been  purchased on, and  continuously
held since, the date on which the shares given in exchange were purchased; thus,
an exchange would not affect the running of any CDSC-related  holding period. No
initial  sales  charge or CDSC would  apply to an exchange of shares of a Charge
Portfolio for shares of Alger Money Market Portfolio,  but redemptions of shares
of that Portfolio  acquired by exchange of shares from one or more of the Charge
Portfolios  are subject to any  applicable  CDSC on the same terms as the shares
given in exchange.  If shares of Alger Money Market  Portfolio are exchanged for
shares of any of the Charge  Portfolios,  any later  redemptions of those shares
would be  subject to any  applicable  CDSC based on the period of time since the
shares given in exchange were purchased.  

The following example  illustrates the operation of the CDSC for active accounts
established prior to October 17, 1992. Assume that on the first day of year 1 an
investor  purchases $1,000 of shares of each of Alger Money Market Portfolio and
Alger  Growth  Portfolio,  Class B. The  shareholder  may at any time redeem the
shares of Alger Money Market Portfolio  without  imposition of the charge. If in
year 3 the shareholder  redeems all the Class B Shares of Alger Growth Portfolio
purchased in year 1, a charge of three percent of the current net asset value of
those shares would be imposed on the redemption.  The  shareholder  could redeem
without imposition of the charge any of his or her shares of that Portfolio that
were purchased through reinvestment of dividends and capital gains distributions
as well as an amount of Class B Shares not  exceeding  any  increase  in the net
asset value of the $1,000 of shares originally purchased.  The shareholder could
also at any time exchange the Class B Shares of Alger Growth Portfolio for Class
B Shares of any other  Portfolio  without  imposition  of the  

                                      -14-


<PAGE>
charge.  If those shares were later redeemed,  however,  the redemption would be
subject to the charge based on the current net asset value of the shares and the
period of time since the original  purchase  payment was made (with  adjustments
for partial  exchanges and redemptions  and any accretions in the  shareholder's
account by reason of increases in net asset value and  reinvestment of dividends
and capital gains  distributions).  If the  foregoing  exchange were made by the
shareholder  for  additional  shares  of  Alger  Money  Market  Portfolio,   any
subsequent  redemption of shares of that Portfolio  would be deemed to have been
made first from the $1,000 of shares of Alger Money Market Portfolio  originally
purchased  in year 1,  which are not  subject to the  charge,  and then from the
shares acquired in the exchange, which are subject to the charge. If instead the
shareholder  exchanged  the shares of Alger Money  Market  Portfolio  originally
purchased in year 1 for additional  Class B Shares of Alger Growth Portfolio (or
of the other Charge  Portfolios)  any later  redemption of those shares would be
subject to the charge in accordance with the foregoing rules based on the period
of time since the original  purchase  payment was made. Thus, the period of time
shares were held in Alger Money  Market  Portfolio  would be counted  toward the
six-year holding period.

FOR NEW  SHAREHOLDERS  OPENING AN ACCOUNT  AFTER  OCTOBER  17,  1992.  Effective
October 17,  1992,  new  shareholders  of the Fund are subject to the  following
terms and conditions  regarding the exchange of shares of the Fund's Portfolios.
A CDSC,  if any, is assessed  on  redemptions  of Class B and Class C Shares and
certain  Class A Shares of the Charge  Portfolios  and of shares of Alger  Money
Market  Portfolio  that have been  acquired in  exchange  for shares of a Charge
Portfolio,  based  solely on the period of time the shares are  retained  in the
Charge Portfolio. Thus, the period of time shares are held in Alger Money Market
Portfolio will not be counted towards the holding period  described above in the
calculation of a CDSC.

The following examples  illustrate the operation of the CDSC for accounts opened
after October 17, 1992: (1) An investor purchases Class B Shares of Alger Growth
Portfolio  on the first day of year 1 and  exchanges  those shares for shares of
Alger Money Market Portfolio in year 2. No charge is assessed at the time of the
exchange.  If in year 4 the shareholder redeems all the shares, a charge of four
percent of the current net asset value of those  shares  would be imposed on the
redemption  based on the period of time the shares  were  retained in Class B of
the Alger  Growth  Portfolio.  The time period  during which the shares of Alger
Money Market Portfolio are held is not included when the amount of the charge is
calculated. The shareholder could redeem without imposition of the charge any of
his shares that were  purchased  through  reinvestment  of dividends and capital
gains distributions as well as an amount of shares not exceeding any increase in
the net asset value of the original  purchase.  (2) An investor purchases shares
of Alger Money Market  Portfolio on the first day of year 1 and exchanges  those
shares for Class B Shares of Alger Growth  Portfolio on the first day of year 2.
No charge is assessed at the time of the exchange.  If in year 4 the shareholder
redeems all the shares, a charge of three percent of the current net asset value
of those shares would be imposed on the  redemption  based on the period of time
the shares were retained in Class B of Alger Growth  Portfolio.  The time period
during which the shares of Alger Money Market Portfolio are held is not included
when the  amount of the  charge is  calculated.  The  shareholder  could  redeem
without  imposition  of the charge any of his or her shares that were  purchased
through  reinvestment of dividends and capital gains distributions as well as an
amount  of shares  not  exceeding  any  increase  in the net asset  value of the
original purchase.

   
CERTAIN ALGER MONEY MARKET PORTFOLIO SHARES
Shares of Alger Money Market  Portfolio  that have been acquired in exchange for
shares of Spectra  Fund (a mutual fund  managed by Alger  Management),  together
with Alger Money  Market  Portfolio  shares  acquired  through  reinvestment  of
dividends on such  shares,  may be  exchanged  for Spectra  Fund  shares.  These
exchanges  will be effected at the  respective  net asset values of Spectra Fund
and Alger Money Market  Portfolio next determined  after the exchange request is
accepted,  with no sales charge or transaction fee imposed. For more information
about such exchanges,  please call (800)  992-3863.  The Alger Fund reserves the
right  to  terminate  or  modify  this   exchange   privilege   upon  notice  to
shareholders.

(iii)  the Plan has less  than 500  eligible  employees,  as  determined  by the

No director,  officer or employee of Alger  Management  or its  affiliates  will
receive any  compensation  from the Fund for serving as an officer or Trustee of
the Fund. The Fund pays each Trustee who is not a director,  officer or employee
of Alger  Management or its affiliates (a  "Disinterested  Trustee") a quarterly
fee of $2,000,  which is reduced by the  proportion of the meetings not attended
by the Trustee during the quarter.

The Fund did not offer its Trustees any pension or retirement benefits during or
prior to the fiscal year ended October 31, 1997.  The following  table  provides
compensation  amounts paid to Disinterested  Trustees of the Fund for the fiscal
year ended October 31, 1997.

INVESTMENT MANAGER
Alger Management serves as investment manager to each of the Portfolios pursuant
to separate  written  agreements (the "Management  Agreements").  Certain of the
services  provided by, and the fees paid by the Portfolios to, Alger  Management
under  the  Management  Agreements  are  described  in  the  Prospectus.   Alger
Management  pays the  salaries of all  officers  who are  employed by it.  Alger
Management has agreed to maintain  office  facilities for the Fund,  furnish the
Fund with  statistical and research data,  clerical,  accounting and bookkeeping
services,  and certain other  services  required by the Fund, and to compute the
net  asset  values,  net  income  and  realized  capital  gains or losses of the
Portfolios.  Alger  Management  prepares  semi-annual  reports to the SEC and to
shareholders,  prepares  federal and state tax  returns  and filings  with state
securities commissions,  maintains the Fund's financial accounts and records and
generally  assists in all  aspects of the Fund's  operations.  Alger  Management
bears all expenses in connection  with the performance of its services under the
Management Agreements. 

Each  Management  Agreement  provides that if, in any fiscal year, the aggregate
expenses of the Portfolio (exclusive of certain specified categories of expense)
exceed  the  expense  limitation  of any  state  having  jurisdiction  over  the
Portfolio, Alger Management will reimburse the Portfolio for that excess expense
to the extent required by state law. At the date of this Statement of Additional
Information,  there is no state expense limitation  applicable to any Portfolio.

   
During the fiscal years ended October 31, 1995, 1996, and 1997, Alger Management
earned under the terms of the  Management  Agreements  $830,000,  $1,214,904 and
$1,104,000  respectively,  in  respect  of the  Alger  Money  Market  Portfolio;
$3,118,000,  $4,478,467,  and $4,715,000  respectively,  in respect of the Alger
Small   Capitalization   Portfolio;    $760,000,   $1,654,488   and   $2,396,000
respectively,  in respect of the Alger Growth Portfolio;  $27,000,  $82,116, and
$96,000  respectively,  in respect of the Alger  Balanced  Portfolio;  $244,000,
$720,696,  and $1,236,000,  respectively,  in respect of the Alger MidCap Growth
Portfolio; and $77,000, $861,617, and $1,587,000 respectively, in respect of the
Alger Capital Appreciation Portfolio.  Some of these fees for Alger Money Market
Portfolio,  however,  were  offset  in  whole  or in  part  by  various  expense
reimbursements and waivers.

DISTRIBUTOR  
Alger  Inc.,  the  corporate  parent of Alger  Management,  serves as the Fund's
principal underwriter, or distributor, and receives payments from the Fund under
the Fund's  Distribution  Plans (see  "Purchases--Distribution  Plans")  and the
Shareholder   Servicing   Agreement   (see   "Purchases--Shareholder   Servicing
Agreement").   It  also  receives  brokerage  commissions  from  the  Fund  (see
"Investment Objectives and Policies--Portfolio Transactions"). During the Fund's
fiscal year ended October 31, 1997, Alger Inc. retained approximately $3,914,000
in CDSCs and $108,000 in initial sales charges. 
    
INDEPENDENT PUBLIC ACCOUNTANTS
Arthur Andersen LLP serves as independent public accountant for the Fund.

TAXES
The following is a summary of selected  federal income tax  considerations  that
may  affect  the Fund and its  shareholders.  The  summary  is not  intended  to
substitute  for  individual  tax advice and investors are urged to consult their
own tax  advisers  as to the  federal,  state  and  local  tax  consequences  of
investing in the Fund.

Each  Portfolio  intends to qualify as a "regulated  investment  company"  under
Subchapter M of the Internal  Revenue Code of 1986, as amended (the "Code").  If
qualified as a regulated  investment  company,  a Portfolio  will pay no federal
income taxes on its taxable net investment income (that is, taxable income other
than net realized  capital  gains) and its net realized  capital  gains that are
distributed to  shareholders.  To qualify under  Subchapter M, a Portfolio must,
among other  things:  (1)  distribute  to its  shareholders  at least 90% of its
taxable net investment  income and net realized  short-term  capital gains;  (2)
derive at least 90% of its gross income from dividends,  interest, payments with
respect  to loans of  securities,  gains from the sale or other  disposition  of
securities, or other income (including,  but 

                                      -18-

<PAGE>
   
not limited to, gains from options,  futures and forward contracts) derived with
respect  to the  Portfolio's  business  of  investing  in  securities;  and  (3)
diversify  its  holdings  so  that,  at the end of each  fiscal  quarter  of the
Portfolio  (a) at least 50% of the  market  value of the  Portfolio's  assets is
represented by cash, U.S. Government securities and other securities, with those
other  securities  limited,  with  respect  to any one  issuer,  to an amount no
greater in value than 5% of the  Portfolio's  total  assets and to not more than
10% of the outstanding  voting  securities of the issuer,  and (b) not more than
25% of the market value of the Portfolio's  assets is invested in the securities
of any one issuer (other than U.S. Government  securities or securities of other
regulated  investment  companies)  or of two or more issuers that the  Portfolio
controls  and  that  are  determined  to be in the  same or  similar  trades  or
businesses or related trades or  businesses.  In meeting these  requirements,  a
Portfolio  may be  restricted in the  utilization  of certain of the  investment
techniques  described  above  and  in  the  Fund's  prospectus.  As a  regulated
investment company,  each Portfolio is subject to a non-deductible excise tax of
4% with  respect to certain  undistributed  amounts of income and capital  gains
during the calendar  year.  The Fund expects each  Portfolio to make  additional
distributions  or  change  the  timing of its  distributions  so as to avoid the
application  of this tax.  Although the Fund expects each Portfolio to make such
distributions  as are necessary to avoid the application of this tax, certain of
such distributions,  if made in January, might be included in the taxable income
of shareholders in the year ended in the previous December.
    

Payments  reflecting the dividend  income of the Portfolios will not qualify for
the  dividends-received  deduction for  corporations  if the Portfolio sells the
underlying stock before satisfying a 46-day holding period  requirement (91 days
for certain preferred stock). Dividends-received deductions will be allowed to a
corporate  shareholder only if similar holding period  requirements with respect
to shares of the Portfolio have been met.

In general,  any gain or loss on the redemption or exchange of Portfolio  shares
will be long-term  capital gain or loss if held by the shareholder for more than
one year,  and will be  short-term  capital gain or loss if held for one year or
less.  However,  if a shareholder  receives a distribution  taxable as long-term
capital  gain with  respect to Portfolio  shares,  and redeems or exchanges  the
shares before holding them for more than six months,  any loss on the redemption
or exchange up to the amount of the distribution  will be treated as a long-term
capital loss.

   
Dividends  of a  Portfolio's  net  investment  income and  distributions  of its
short-term  capital gains will be taxable as ordinary  income.  Distributions of
long-term  capital  gains  will be  taxable  as such  at the  appropriate  rate,
regardless of the length of time you have held shares of the  Portfolio.  If you
receive a  distribution  treated as long-term  capital gain with respect to Fund
shares,  and you redeem or exchange the shares before holding them for more than
six  months,  any loss on the  redemption  or  exchange  up to the amount of the
distribution  will be treated as long-term  capital loss.  Only  dividends  that
reflect  a  Portfolio's  income  from  certain  dividend-paying  stocks  will be
eligible   for  the   federal   dividends-received   deduction   for   corporate
shareholders. None of the dividends paid by Alger Money Market Portfolio will be
eligible for the dividends-received deduction.
    

If a  Portfolio  is the holder of record of any stock on the record date for any
dividends payable with respect to such stock, such dividends are included in the
Portfolio's  gross  income  as of the later of (a) the date  such  stock  became
ex-dividend  with respect to such dividends  (i.e., the date on which a buyer of
the stock would not be entitled to receive the declared, but unpaid,  dividends)
or (b) the date the  Portfolio  acquired  such stock.  Accordingly,  in order to
satisfy its income distribution requirements, a Portfolio may be required to pay
dividends based on anticipated  earnings and shareholders may receive  dividends
in an earlier year than would otherwise be the case.

Investors  considering  buying shares of a Portfolio just prior to a record date
for a taxable  dividend  or  capital  gain  distribution  should be aware  that,
regardless of whether the price of the Portfolio shares to be purchased reflects
the amount of the forthcoming dividend or distribution payment, any such payment
will be a taxable dividend or distribution payment.

If a  shareholder  fails to furnish a correct  taxpayer  identification  number,
fails to fully report dividend or interest  income,  or fails to certify that he
or she has provided a correct taxpayer  identification number and that he or she
is not subject to such withholding,  then the shareholder may be subject to a 31
percent "backup  withholding tax" with respect to (i) any taxable  dividends and
distributions  and  (ii) any  proceeds  of any  redemption  of Fund  shares.  An
individual's  taxpayer  identification  number  is his or  her  social  security
number.  The 31 percent backup  withholding tax is not an additional tax and may
be credited against a shareholder's regular federal income tax liability.

CUSTODIAN AND TRANSFER AGENT

   State  Street  Bank  and  Trust  Company,   225  Franklin   Street,   Boston,
Massachusetts  02110  serves as custodian  for the Fund  pursuant to a custodian

under which it holds the Portfolios' assets. Alger Shareholder  Services,  Inc.,
30 Montgomery  Street,  Jersey City, New Jersey 07302,  serves as transfer agent
for the Fund pursuant to a transfer agency agreement.  Under the transfer agency
agreement Alger Shareholder  Services,  Inc. processes purchases and redemptions
of  shares of the Fund,  maintains  the  shareholder  account  records  for each
Portfolio,  handles certain communications between shareholders and the Fund and
distributes any dividends and distributions payable by the Fund.

ORGANIZATION
The Fund has been organized as an  unincorporated  business trust under the laws
of the Commonwealth of Massachusetts pursuant to an Agreement and Declaration of
Trust  dated  March  20,  1986  (the  "Trust  Agreement").  Alger  Money  Market
Portfolio,  Alger Small  Capitalization  Portfolio  and Alger  Growth  Portfolio
commenced  operations on November 11, 1986. Alger Balanced  Portfolio  commenced
operations on June 1, 1992, Alger MidCap Growth Portfolio  commenced  operations
on May 24, 1993 and Alger Capital Appreciation Portfolio commenced operations on
November 1, 1993. Prior to March 27, 1995 Alger Capital  Appreciation  Portfolio
was known as Alger Leveraged  AllCap  Portfolio.  The word "Alger" in the Fund's
name has been adopted pursuant to a provision  contained in the Trust Agreement.
Under that provision,  Alger  Management may terminate the Fund's license to use
the word "Alger" in its name when Alger  Management  ceases to act as the Fund's
investment  manager.  On  December  31,  1996,  Class A Shares were added to all
portfolios of the Fund except Alger Money Market Portfolio.  Class A shares have
an initial sales charge.  

                                      -21-

<PAGE>
The previously  existing  shares in those  portfolios,  subject to a CDSC,  were
designated Class B Shares on that date.  Class C Shares,  which are subject to a
CDSC, were created on August 1, 1997.

   
Shares of each  Portfolio  other  than Alger  Money  Market  Portfolio  are thus
divided into three classes,  Class A, Class B and Class C. The classes differ in
that:  (a) each class has a different  class  designation;  (b) only the Class A
Shares  are  subject  to an initial  sales  charge;  (c) the Class B and Class C
Shares are subject to CDSCs, and certain Class A Shares may also be subject to a
CDSC;  (d) only the Class B and Class C Shares (as described  below) are subject
to  distribution  fees under plans adopted  pursuant to Rule 12b-1 under the Act
(each, a "Rule 12b-1 Plan");  (e) to the extent that one class alone is affected
by a matter  submitted to a vote of the  shareholders,  then only that class has
voting  power on the matter;  and (f) the  exchange  privileges  and  conversion
rights of each class differ from those of the others.
    

Shares do not have  cumulative  voting rights,  which means that holders of more
than 50 percent of the shares  voting for the election of Trustees can elect all
Trustees.  Shares  are  transferable  but  have  no  preemptive,  conversion  or
subscription  rights.  Shareholders  generally  vote by  Portfolio,  except with
respect to the election of Trustees  and the  ratification  of the  selection of
independent accountants, and by class within a Portfolio on matters in which the
interests  of one class  differ from those of another;  see also item (e) in the
preceding  paragraph.  In the interest of economy and convenience,  certificates
representing  shares of a Portfolio  are  physically  issued only upon  specific
written request of a shareholder.

Meetings of  shareholders  notmally will not be held for the purpose of electing
Trustees  unless  and until such time as less than a  majority  of the  Trustees
holding  office have been  elected by  shareholders,  at which time the Trustees
then in office will call a  shareholders'  meeting for the election of Trustees.
Under  the  Act,  shareholders  of  record  of no less  than  two-thirds  of the
outstanding  shares of the Fund may remove a Trustee  through a  declaration  in
writing  or by vote  cast in person  or by proxy at a  meeting  called  for that
purpose. Under the Trust Agreement,  the Trustees are required to call a meeting
of shareholders for the purpose of voting on the question of removal of any such
Trustee when requested in writing to do so by the  shareholders of record of not
less than 10 percent of the Fund's outstanding shares.

Massachusetts law provides that shareholders could, under certain circumstances,
be held personally  liable for the obligations of the Fund.  However,  the Trust
Agreement  disclaims  shareholder  liability for acts or obligations of the Fund
and  requires  that  notice  of such  disclaimer  be  given  in each  agreement,
obligation or instrument entered into or executed by the Fund or a Trustee.  The
Trust Agreement  provides for  indemnification  from the Fund's property for all
losses  and  expenses  of  any  shareholder  held  personally   liable  for  the
obligations of the Fund. Thus, the risk of a shareholder's  incurring  financial
loss on account of shareholder  liability is limited to  circumstances  in which
the Fund itself would be unable to meet its obligations,  a possibility that the
Fund believes is remote. Upon payment of any liability incurred by the Fund, the
shareholder  paying the  liability  will be entitled to  reimbursement  from the
general assets of the Fund. The Trustees intend to conduct the operations of the
Fund in a manner so as to avoid, as far as possible,  ultimate  liability of the
shareholders for liabilities of the Fund.


DETERMINATION OF PERFORMANCE

ALGER MONEY MARKET PORTFOLIO

   
The Alger Money Market Portfolio's  "yield" and "effective yield" referred to in
the Prospectus are calculated  according to formulas  prescribed by the SEC. The
Portfolio's  seven-day  "yield"  is  computed  by  determining  the net  change,
exclusive of capital  changes and income other than  investment  income,  in the
value of a hypothetical  pre-existing  account in the Portfolio having a balance
of one share at the beginning of the period,  dividing the net change in account
value by the value of the account at the  beginning of the base period to obtain
the base period return,  and then multiplying the base period return by (365/7).
The Portfolio's  "effective  yield" is computed by compounding the  unannualized
base period return  (calculated as above),  by adding one to it, raising the sum
to a power equal to 365 divided by seven,  and  subtracting one from the result.
When Alger Money Market Portfolio includes  quotations of "yield" and "effective
yield" that are based on income generated by an investment in the Portfolio over
a thirty-day, or one month, period, it will calculate the "yield" and "effective
yield" in the manner described above except that, in annualizing the "yield" and
"effective yield," the formula will be adjusted to reflect the proper period.

For the seven-day period ended October 31, 1997, the annualized yield was 4.83%,
and the compounded effective yield was 4.94%.
    

OTHER PORTFOLIOS
The "total  return" and "yield"  referred to in the Prospectus as to each of the
Classes of the  Portfolios,  other than Alger Money Market  Portfolio,  are also
computed according to formulas  prescribed by the SEC. These performance figures
are calculated in the following manner:

                                      -22-

<PAGE>
A. Total Return--A Class' average annual total return described in the 
   Prospectus is computed according to the following formula:

                                  P (1+T)n=ERV

Where:   P =   a hypothetical initial payment of $1,000
         T =   average annual total return
         n =   number of years
       ERV =   ending  redeemable value of a hypothetical  $1,000 payment made
               at the  beginning  of the 1, 5, or 10 year  periods at the end of
               the 1, 5 and 10 year periods (or fractional portion thereof);

   
   The  average  annual  total  returns  for  Class  A,  B and C  Shares  of the
Portfolios,  other than Alger Money Market Portfolio,  for the periods indicated
below were as follows:

                 YIELD = 2[(----- + 1)6 - 1]
                              cd
Where:    a = dividends and interest earned during the period.
          b = expenses accrued for the period (net of reimbursements).
          c = The average daily number of shares  outstanding  during the period
              that were  entitled to receive  dividends.  
          d = the  maximum  offering price per share on the last day 
              of the period.

IN GENERAL

Current  performance  information  for  the  Classes  of the  Portfolios  may be
obtained by calling the Fund at (800)  992-3863.  Quoted  performance may not be
indicative of future  performance.  The  performance of a Class will depend upon
factors such as its expenses and the types and maturities of securities  held by
the Portfolio.

   
From time to time,  advertisements  or reports to  shareholders  may compare the
yield or  performance  of a  Portfolio  with that of other  mutual  funds with a
similar  investment  objective.  The yield of the Alger Money  Market  Portfolio
might be compared with, for example,  averages compiled by IBC/DONOGHUE'S  MONEY
FUND REPORT,  a widely  recognized,  independent  publication  that monitors the
performance  of money market mutual  funds.  The yield of the Alger Money Market
Portfolio  might also be compared  with the average  yield  reported by the Bank
Rate Monitor for money market deposit  accounts  offered by the 50 leading banks
and thrift institutions in the top five standard metropolitan areas.  Similarly,
the  performance of the other  Portfolios,  for example,  might be compared with
rankings  prepared  by  Lipper  Analytical  Services  Inc.,  which  is a  widely
recognized,  independent  service that monitors the performance of mutual funds,
as  well as with  various  unmanaged  indices,  such as the S&P 500  Index,  the
Russell  2000 Growth  Index,  the S&P SmallCap  600 Index,  the  Wilshire  Small
Company Growth Index, the Lehman Brothers Government/Corporate Bond Index or the
S&P MidCap 400 Index.  In addition,  evaluations of the Portfolios  published by
nationally  recognized  ranking  services  or  articles  regarding  performance,
rankings and other Portfolio characteristics may appear in national publications
including,  but not limited to, BARRON'S,  BUSINESS WEEK, FORBES,  INSTITUTIONAL
INVESTOR,  INVESTOR'S  BUSINESS  DAILY,  KIPLINGER'S  PERSONAL  FINANCE,  MONEY,
MORNINGSTAR,  THE NEW YORK TIMES,  USA TODAY and THE WALL STREET JOURNAL and may
be included in  advertisements  or  communications  to  shareholders.  Any given
performance  comparison  should  not be  considered  as  representative  of such
Portfolio's performance for any future period.

designation.  Capacity for timely  payment on issues with an A-2  designation is
strong.  However,  the  relative  degree of safety is not as high as for  issues
designated A-l.

The rating  Prime-l  (P-l) is the highest  commercial  paper rating  assigned by
Moody's.  Issuers of P-l paper must have a superior  capacity  for  repayment of
short term  promissory  obligations  and ordinarily will be evidenced by leading
market positions in well established  industries,  high rates of return of funds
employed,  conservative capitalization structures with moderate reliance on debt
and  ample  asset  protection,  broad  margins  in  earnings  coverage  of fixed
financial charges and high internal cash generation, and well established access
to a range of  financial  markets and assured  sources of  alternate  liquidity.
Issues rated  Prime-2  (P-2) have a strong  capacity for repayment of short-term
promissory  obligations.  This  ordinarily  will  be  evidenced  by  many of the
characteristics  cited above but to a lesser degree Earnings trends and coverage
ratios,  while  sound,  will  be  more  subject  to  variation.   Capitalization
characteristics,  while  still  appropriate,  may be more  affected  by external
conditions. Ample alternate liquidity is maintained.

The rating  Fitch-l  (Highest  Grade) is the  highest  commercial  paper  rating
assigned  by Fitch.  Paper rated  Fitch-l is  regarded  as having the  strongest
degree of assurance for timely payment.  The rating Fitch-2 (Very Good Grade) is
the second highest  commercial  paper rating assigned by Fitch which reflects an
assurance of timely  payment  only  slightly  less in degree than the  strongest
issues.

The rating Duff-l is the highest commercial paper rating assigned by Duff. Paper
rated Duff-l is regarded as having very high  certainty  of timely  payment with
excellent liquidity factors which are supported by ample asset protection.  Risk
factors are minor.  Paper rated  Duff-2 is regarded as having good  certainty of
timely payment,  good access to capital markets and sound liquidity  factors and
company fundamentals. Risk factors are small.

BOND AND LONG-TERM RATINGS

Bonds rated AA by S&P are judged by S&P to be high-grade  obligations and in the
majority of  instances  differ only in small degree from issues rated AAA (S&P's
highest  rating).  Bonds rated AAA are considered by S&P to be the highest grade
obligations  and possess the ultimate  degree of  protection as to principal and
interest. With AA bonds, as with AAA bonds, prices move with the long-term money
market.  Bonds  rated A by S&P  have a  strong  capacity  to pay  principal  and
interest,  although they are somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions.

S&P's BBB rated bonds, or medium-grade  category bonds,  are borderline  between
definitely sound  obligations and those where the speculative  elements begin to
predominate. These bonds have adequate asset coverage and normally are protected
by  satisfactory   earnings.   Their   susceptibility  to  changing  conditions,
particularly  to  depressions,   necessitates  constant  watching.  These  bonds
generally are more responsive to business and trade  conditions than to interest
rates. This group is the lowest that qualifies for commercial bank investment.

Bonds  rated Aa by Moody's  are judged to be of high  quality by all  standards.
Together  with bonds rated Aaa (Moody's  highest  rating) they comprise what are
generally  known as  high-grade  bonds.  Aa bonds are rated lower than Aaa bonds
because  margins of  protection  may not be as large as those of Aaa  bonds,  or
fluctuation of protective elements may be of greater amplitude,  or there may be
other elements present that make the long-term risks appear somewhat larger than
those  applicable to Aaa  securities.  Bonds that are 

                                      A-1

APPENDIX
(continued)

rated A by Moody's  possess many favorable  investment  attributes and are to be
considered  as upper  medium  grade  obligations.  Factors  giving  security  to
principal and interest are considered adequate, but elements may be present that
suggest a susceptibility to impairment in the future.

Moody's Baa rated bonds are considered as medium-grade  obligations,  i.e., they
are neither highly protected nor poorly secured. Interest payments and principal
security appear adequate for the present, but certain protective elements may be
lacking or may be  characteristically  unreliable over any great length of time.
Such  bonds lack  outstanding  investment  characteristics  and,  in fact,  have
speculative characteristics as well.

Moody's  applies  the  numerical  modifiers  1, 2 and 3 to each  generic  rating
classification  from Aa through B. The  modifier 1 indicates  that the  security
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range  ranking;  and the modifier 3 indicates  that the issue ranks in the
lower end of its generic rating category.

Bonds rated AAA by Fitch are judged by Fitch to be strictly high grade,  broadly
marketable,  suitable for investment by trustees and fiduciary  institutions and
liable to but slight market  fluctuation other than through changes in the money
rate. The prime feature of an AAA bond is a showing of earnings several times or
many times interest  requirements,  with such  stability of applicable  earnings
that safety is beyond reasonable  question whatever changes occur in conditions.
Bonds  rated AA by Fitch are  judged by Fitch to be of safety  virtually  beyond
question and are readily  salable,  whose merits are not unlike those of the AAA
class, but whose margin of safety is less strikingly broad. The issue may be the
obligation of a small company,  strongly  secured but influenced as to rating by
the lesser financial power of the enterprise and more local type of market.

Bonds rated Duff-l are judged by Duff to be of the highest  credit  quality with
negligible risk factors; only slightly more than U.S. Treasury debt. Bonds rated
Duff-2,  3 and 4 are judged by Duff to be of high  credit  quality  with  strong
protection  factors.  Risk is  modest  but may vary  slightly  from time to time
because of economic conditions.

Item 27.   Indemnification

     Under Section 8.4 of Registrant's  Agreement and Declaration of Trust,  any
past or present Trustee or officer of Registrant (including persons who serve at
Registrant's request as directors,  officers or Trustees of another organization
in  which   Registrant   has  any  interest  as  a   shareholder,   creditor  or
otherwise[hereinafter  referred to as a "Covered Person"]) is indemnified to the
fullest extent  permitted by law against  liability and all expenses  reasonably
incurred by him in  connection  with any action,  suit or proceeding to which he
may be a party or  otherwise  involved  by reason of his being or having  been a
Covered  Person.  This provision does not authorize  indemnification  when it is
determined,  in the manner  specified in the Agreement and Declaration of Trust,
that such Covered  Person has not acted in good faith in the  reasonable  belief
that his actions  were in or not opposed to the best  interests  of  Registrant.
Moreover,  this  provision  does  not  authorize   indemnification  when  it  is
determined , in the manner  specified in the Agreement and Declaration of Trust,
that  such  Covered  Person  would  otherwise  be liable  to  Registrant  or its
shareholders by reason of willful  misfeasance,  bad faith,  gross negligence or
reckless disregard of his duties.  Expenses may be paid by Registrant in advance
of the final  disposition of any action,  suit or proceeding  upon receipt of an
undertaking  by such Covered  Person to repay such expenses to Registrant in the
event that it is ultimately  determined that indemnification of such expenses is
not authorized  under the Agreement and  Declaration of Trust and either (i) the
Covered  Person  provides  security for such  undertaking,  (ii)  Registrant  is
insured against losses from such advances,  or (iii) the disinterested  Trustees
or  independent  legal  counsel  determines,  in  the  manner  specified  in the
Agreement and Declaration of Trust,  that there is reason to believe the Covered
Person will be found to be entitled to indemnification.

     Insofar as  indemnification  for liability arising under the Securities Act
of 1933 (the  "Securities  Act") may be  permitted  to  Trustees,  officers  and
controlling  persons of  Registrant  pursuant to the  foregoing  provisions,  or
otherwise, Registrant has been advised that in the opinion of the Securities and
Exchange Commission (the "SEC") such indemnification is against public policy as
expressed in the Securities Act and is, therefore,  unenforceable.  In the event
that a claim  for  indemnification  against  such  liabilities  (other  than the
payment by  Registrant  of expenses  incurred  or paid by a Trustee,  officer or
controlling person of Registrant in the successful  defense of any action,  suit
or  proceeding) is asserted by such Trustee,  officer or  controlling  person in
connection with the securities being registered,  Registrant will, unless in the
opinion of its counsel  the matter has been  settled by  controlling  precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against  public policy as expressed in the  Securities
Act and will be governed by the final adjudication of such issue.

Item 28.   Business and Other Connections of Investment Adviser

     Alger  Management,  which serves as investment  manager to  Registrant,  is
generally engaged in rendering investment advisory services to institutions and,
to a lesser extent, individuals. Alger Management presently serves as investment
adviser  to two  closed-end  investment  companies  and to  two  other  open-end
investment  companies.  The list  required by this Item 28  regarding  any other
business, profession,  vocation or employment of a substantial nature engaged in
by  officers  and  directors  of Alger  Management  during the past two years is
incorporated  by  reference  to  Schedules  A and D of Form  ADV  filed by Alger
Management  pursuant  to the  Investment  Advisers  Act of 1940  (SEC  File  No.
801-06709).

Item 29.   Principal Underwriter

     (a) Alger Inc.  acts as principal  underwriter  for  Registrant,  The Alger
American  Fund,  Spectra  Fund and The  Alger  Retirement  Fund and has acted as
subscription agent for Castle Convertible Fund, Inc. and Spectra Fund, Inc.

     (b) The information required by this Item 29 with respect to each director,
officer or partner of Alger Inc. is  incorporated  by reference to Schedule A of
Form BD filed by Alger Inc. pursuant to the Securities Exchange Act of 1934 (SEC
File No. 8-6423).
