Example:

Assume an annual  return is 5% and no change in the level of expenses  described
above.  For  a  $1,000  investment,  with  reinvestment  of  all  dividends  and
distributions,  you would pay the  following  total  expenses if you closed your
account after the number of years indicated.

                       1 year    3 years   5 years   10 years

Class A shares(4)        $9        $27       $48       $106
Class B shares(4)        $56       $81       $98       $171(5)
Class C shares(4)        $9        $27       $48       $106

(1) Sales  "load" is referred  to as sales  "charge",  "deferred  sales load" is
referred to as  "contingent  deferred sales charge" (or "CDSC") and "12b-1 fees"
which  consist of a "service  fee" and a  "distribution  fee" are referred to by
either or both of these terms where appropriate with respect to Class A, Class B
and Class C shares  throughout this  Prospectus.  (2)The Fund has no Class A and
Class C CDSC of its own but it does  have its own  Class B CDSC.  The Fund  will
collect  Class A and Class C CDSCs on behalf of the other Lord Abbett  funds and
the Class B CDSC on behalf of Lord Abbett  Distributor  LLC. See  "Collection of
CDSCs by the Fund" and "Acquiring Class B Shares", both under "Purchases". Other
Lord Abbett-sponsored funds have instituted Class A and Class C Rule 12b-1 plans
that  provide for a CDSC on such shares  subject to a Rule 12b-1 fee of up to 1%
paid  under  such a plan where  those  shares  (or any  shares of  another  fund
received in exchange for those  shares) are redeemed  within 24 months after the
month of  purchase  (in the case of Class A  shares)  and  within  12  months of
purchase (in the case of Class C shares).  The Fund pays no Rule 12b-1 fees with
respect  to Class A or Class C  shares.  With  respect  to  Class B  shares,  an
"anniversary"  is in the 365th day  subsequent  to the original  purchase,  or a
prior anniversary of such purchase,  of "B Exchanged Shares", i.e. shares of the
same class of another  Lord  Abbett-sponsored  fund used in an exchange  for the
Fund's Class B shares.  (3)Although the Fund does not, with respect to the Class
B shares,  charge a  front-end  sales  charge,  investors  should be aware  that
long-term  shareholders  may pay,  under the Rule 12b-1 plan  applicable  to the
Class B shares of the Fund (which pays annual  0.75%  distribution  fees),  more
than the economic  equivalent of the maximum front-end sales charge as permitted
by certain rules of the National Association of Securities Dealers,  Inc. (4)The
annual  operating  expenses shown in the summary are the actual expenses for the
Fund for the fiscal  year ended June 30,  1995  except for the  substitution  of
estimated  12b-1  fees for Class B shares.  (5)Based  on  conversion  of Class B
shares to Class A shares on the eighth  anniversary  of the  purchase of Class B
shares and closing your account by redeeming Class A shares after ten years. The
foregoing is provided to give investors a better  understanding  of the expenses
that are incurred by an investment in the Fund.

Government,  its agencies or instrumentalities.  These obligations which must be
eligible  investments for a money market fund include: (1) obligations issued by
the U.S. Treasury,  differing only in their interest rates,  maturities and time
of issuance,  and including  Treasury bills, notes and bonds and (2) obligations
issued or guaranteed by U.S. Government agencies and instrumentalities which are
supported by any of the  following:  (a) the full faith and credit of the United
States (such as GNMA  certificates),  (b) the right of the issuer to borrow from
the U.S. Treasury or (c) the credit of the agency or  instrumentality.  Agencies
and  instrumentalities  include  Federal  Home  Loan  Banks,  Federal  Home Loan
Mortgage Association, Federal National Mortgage Association, Federal Farm Credit
Banks and Student Loan Marketing Association.  With respect to not more than 35%
of the Fund's  total  assets,  the Fund may invest in  high-quality,  short-term
liquid  securities,   including  certificates  of  deposit  of  domestic  banks,
corporate  commercial  paper,  banker's  acceptances,   repurchase   agreements,
corporate bonds and notes and other debt instruments.
<PAGE>

We seek to keep  money at work in what we  consider  to be the  most  attractive
short-term  debt  investments  consistent  with our  objective.  We  invest in a
portfolio of short-term liquid securities which have maturities of not more than
12 months from the date of settlement of our purchase,  which may include, among
other  investments,  the following.  Bank  Obligations.  Obligations  (including
certificates of deposit and banker's  acceptances) of U.S. banks and savings and
loan  associations  which at the date of their latest public reporting had total
assets in excess of $1 billion and  capital,  surplus and  undivided  profits in
excess of $100 million.

Commercial  Paper.  Commercial paper (short-term  unsecured  promissory notes of
corporations including variable amount master demand notes) which at the date of
investment  is rated A-1 by  Standard  & Poor's  Corporation  ("S&P")  or P-1 by
Moody's  Investors  Service,  Inc.  ("Moody's")  or, if not rated,  is issued by
companies  having  outstanding  debt  rated  AAA  or AA by  S&P  or Aaa or Aa by
Moody's. Short-term Corporate Debt Securities.  Corporate debt securities (bonds
and  debentures)  with no more than 12 months  remaining  to maturity at date of
settlement and rated AAA or AA by S&P or Aaa or Aa by Moody's.

Repurchase  Agreements.  Repurchase  agreements  with (i) any member bank of the
Federal Reserve System or primary dealer in U.S. Government securities or (ii) a
broker-dealer  for  periods  not to  exceed  30 days and only  with  respect  to
underlying  money market  securities which throughout the period have a value at
least equal to the amount of the repurchase price (including  accrued interest).
Concentration.  We will not invest more than 25% of our assets,  taken at market
value, in the securities of issuers in any one industry, except that there is no
percentage  limitation on our investments in obligations issued or backed by the
U.S. Government, its agencies or instrumentalities as described above.

We may invest in obligations  (for example,  commercial paper with a bank letter
of credit or commercial paper of a subsidiary  accompanied by a guarantee of the
parent)  other than those listed above if the  obligation  is  accompanied  by a
guarantee of principal  and  interest,  provided that the guarantee is that of a
bank or  corporation  whose  obligations  we may  otherwise  purchase.  Any such
obligation and guarantee must be due within no more than 12 months from the date
of settlement of our purchase.

We have no present  plans to change  our  policies  with  regard to the types or
maturities of securities in which we invest.  However,  if we determine that our
investment  objective can best be achieved by a change in  investment  policy or
strategy,  we may make such a change without shareholder  approval by disclosing
it in our Prospectus.

Rule 2a-7.  In addition to the  foregoing,  our  investment  practices  are also
governed by certain portfolio maturity, diversification and quality requirements
contained in Rule 2a-7,  as amended,  under the  Investment  Company Act of 1940
(the "Rule").  The Rule imposes these  requirements on the Fund, both because we
hold  ourselves out as a "money market fund" and because we employ the amortized
cost method of valuing our portfolio  securities  (see also "Net Asset  Value").
The  Rule's  maturity  requirements  limit the  Fund's  dollar-weighted  average
portfolio  maturity  to not more  than 90 days and the  maturity  of any  single
portfolio  instrument  to not  more  than  397  days.  Generally  speaking,  the
diversification  provisions  of the  Rule  limit  our  investments  in  (i)  the
securities  of  any  one  issuer,  other  than  U.S.  Government  securities  or
repurchase   agreements  fully  collateralized  by  U.S.  Government  securities
(limited to 5% of our total assets,  except with respect to certain  investments
held for three business days or less),  (ii) securities  issued by or subject to
puts from any single  institution  (limited to 5% of total  assets,  except that
unconditional puts are treated less restrictively) and (iii) securities that are
neither  rated nor  comparable  in quality to  securities  that are rated in the
highest category by a requisite number of rating agencies (generally, limited to
5% of our total  assets  overall  and the  greater  of $1 million or 1% of total
assets in such  securities of one issuer).  Finally,  as to the "quality" of our
portfolio  securities,  the Rule  permits us to invest only in  securities  that
present minimal credit risks as determined by Lord, Abbett & Co. ("Lord Abbett")
(where such determination is delegable by the Board of Directors under the Rule)
or by the Board of Directors  (where not  delegable)  and that  satisfy  certain
requirements  in the Rule  relating to ratings by  nationally-recognized  rating
organizations.
<PAGE>

If the Board of  Directors  should  determine  that  continuing  to abide by the
conditions of the Rule is not in the best interest of our shareholders, we would
neither  use  amortized  cost nor hold  ourselves  out as a money  market  fund.
However,   we  would  continue  to  comply  with  our  remaining   policies  and
restrictions.

5    NET ASSET VALUE

The net asset value of our shares is  calculated  twice on each day that the New
York Stock  Exchange  is open for  trading;  at 12 noon and at 2 P.M.  (New York
time).  Securities are valued at cost plus (minus) amortized discount (premium),
if any,  pursuant to the Rule. The conditions of the Rule are briefly  described
above under "How We Invest".

6    PURCHASES

ALTERNATIVE SALES ARRANGEMENTS
Classes of Shares.  The Fund offers investors three different classes of shares.
The different  classes of shares represent  investments in the same portfolio of
securities but are subject to different  expenses and will likely have different
dividends and yields.  Investors should read this section carefully to determine
which  class  represents  the  best  investment   option  for  their  particular
situation.

Class A  Shares.  If you buy  Class A shares,  you pay no sales  charge.  If you
acquire  Class A shares in exchange for shares of the same class of another Lord
Abbett-sponsored fund subject to a contingent deferred sales charge ("CDSC") and
you redeem any of the Class A shares  within 24 months  after the month in which
you initially purchased shares of such fund, the Fund will collect for such fund
a CDSC of 1% which is  remitted  to such fund to  reimburse  it. The CDSC and an
inactive Rule 12b-1 Plan for Class A shares are described in "Acquiring  Class A
Shares" and "Collection of CDSCs by the Fund" below.

Class B Shares.  Class B shares may only be acquired  in exchange  for shares of
the same class of another Lord Abbett-sponsored  fund. See "Shareholder Services
- --  Telephone  Exchanges"  below.  If you redeem  your  shares  before the sixth
anniversary  of the initial  purchase of shares of such fund,  you will normally
pay a CDSC to Lord  Abbett  Distributor  LLC  (hereinafter  referred to as "Lord
Abbett  Distributor").  That CDSC varies  depending  on how long you own shares.
Class B shares are subject to distribution  fees at an annual rate of 0.75 of 1%
of the annual net asset value of the Class B shares. The CDSC and the Rule 12b-1
Plan  applicable  to the Class B shares  are  described  in  "Acquiring  Class B
Shares" and "Class B Rule 12b-1 Plan" below.

Class C Shares.  Class C shares may only be acquired  in exchange  for shares of
the same class of another Lord Abbett-sponsored  fund. See "Shareholder Services
- --  Telephone  Exchanges"  below.  If you redeem  your  shares  before the first
anniversary  of the initial  purchase of shares of such fund,  you will normally
pay the Fund a CDSC of 1% which is  remitted to such fund to  reimburse  it. The
CDSC and an  inactive  Rule  12b-1  Plan for  Class C shares  are  described  in
"Acquiring Class C Shares" and "Collection of CDSCs by the Fund" below.
<PAGE>

GENERAL
How Much Must You Invest.  The minimum  initial  investment for Class A, B and C
shares  is  $1,000  for  regular  accounts;  $250 for  IRAs,  403(b)  plans  and
"Retirement Plans" (i.e.  employer-sponsored retirement plans under the Internal
Revenue Code). We may waive the initial  investment  minimum for plans involving
continuous investments.  Subsequent investments can be made in any amount. There
is no sales charge except for the Class B shares which have an asset-based sales
charge of .75 of 1%. See "Class B 12b-1 Plan" below.  Our shares (Class A, B and
C) are continuously  offered at their net asset value (normally $1.00 per share)
next  determined  after the  purchase  order in proper  form is received by Lord
Abbett. Class B and C shares may be purchased only by exchange for shares of the
same class of another Lord  Abbett-sponsored  fund, as discussed  below.  Proper
purchase order form includes federal funds received by our custodian bank.

How Do You Open An Account?  You may open an account  either by mail or wire. To
open an account by mail,  send the  completed  Application  Form plus payment to
Lord Abbett U.S. Government Securities Money Market Fund, Inc., P.O. Box 419576,
Kansas City,  Missouri 64141.  Checks should be made payable to Lord Abbett U.S.
Government Securities Money Market Fund, Inc.

To open an account by wire,  first call us at  800-821-5129 to obtain an account
number.  You should direct payment wired in federal funds to our custodian bank,
United  Missouri  Bank of Kansas  City,  N.A.,  Tenth and  Grand,  Kansas  City,
Missouri and specify the name of the Fund and your  account  number in the wire.
The Fund is not responsible for any delays in the wiring system.

In accordance with our investment  objective,  we intend to be invested as fully
as  possible  at all times.  Since we will be  investing  in  instruments  which
normally  require  immediate  payment in federal funds  (monies  credited to our
custodian  bank's  account  with its regional  Federal  Reserve  Bank),  if your
purchase order in all other  respects is found to be in proper form,  payment to
complete a proper order normally will be considered received as follows.

1. Payment  transmitted  by federal  funds wire -- if wire and order,  in proper
form, are received by Lord Abbett  Distributor  prior to 12 noon (New York time)
dividends  begin  accruing on the day of receipt.  If wire and order,  in proper
form, are received after 12 noon (New York time) dividends begin accruing on the
following business day.

2. Payment by check or other  negotiable bank draft drawn on U.S. banks -- after
receipt of an order in proper form by Lord Abbett  Distributor,  dividends begin
accruing on the  business  day on which the federal  funds  represented  by such
check or draft are made available to our custodian bank. Checks drawn on foreign
banks will not be accepted unless  provision is made for payment in U.S. dollars
through a U.S. bank.

A purchase or  redemption  order is in proper  form when it contains  all of the
information   and   documentation   required  by  the  order  form  or  required
supplementally  by Lord Abbett  Distributor  or the Fund to carry out the order.
Payments must be converted to federal  funds by being  credited to our custodian
bank's account with its Federal  Reserve Bank. For required  signatures,  if the
signer  has  any  legal  capacity,  the  signature  and  such  capacity  must be
guaranteed by an eligible  guarantor.  Certain  legal  documents may be required
from corporations or other  organizations,  executors,  trustees and others in a
fiduciary or  representative  capacity.  If you have any questions  concerning a
purchase or redemption, call the Fund at 800-821-5129.

Subsequent  investments can be made either by mail or wire. We reserve the right
to withdraw all or any part of the offering made by this Prospectus or to reject
any purchase  order.  We also reserve the right to waive,  increase or establish
minimum  investment  requirements.  All  purchase  orders  are  subject  to  our
acceptance  and are not binding  until  confirmed or accepted in writing.  Stock
certificates  are  issued  only upon  request  for  Class A shares  and no stock
certificates are issued for fractional shares or Class B and C shares.
<PAGE>

Acquiring  Class A Shares.  Class A shares are sold directly to investors at net
asset  value  per share  without  a sales  charge  and also may be  acquired  in
exchange  for shares of the same class of any other Lord  Abbett-sponsored  fund
(an "initial fund"). Class A shares normally will be subject to a 1.0% CDSC when
redeemed  for cash on or before  the end of the  twenty-fourth  month  after the
month in which they were first purchased if the initial fund paid a distribution
fee on such shares  under its Class A 12b-1  plan.  The CDSC will be assessed on
the lesser of the net asset value of the shares at the time of redemption or the
original  purchase price.  The CDSC is not imposed on the amount of your account
value  represented by the increase in net asset value over the initial  purchase
price (including  increases due to the  reinvestment of dividends).  The Class A
CDSC is paid to the Fund for  remittance to the initial fund to reimburse it, in
whole or in part,  for the service and  distribution  fee payments  made by that
initial fund at the time such shares were first sold.

Class A Rule 12b-1 Plan. The service fees described  below are not being paid by
the Fund and have not been paid  since the  effective  date of the Class A share
Rule  12b-1 Plan (the "A Plan") on July 12,  1996 and,  in  connection  with the
Fund's prior plan, since July 1, 1992.

The A Plan  authorizes  the  Fund  to  pay  service  fees  through  Lord  Abbett
Distributor to authorized  institutions (except with respect to certain accounts
for  which  tracking  data is not  available)  in  order to  provide  additional
incentives for them to provide continuing information and investment services to
their Class A  shareholder  accounts and  otherwise  to encourage  their Class A
accounts  to remain  invested  in the Fund.  The  annual  service  fee  (payable
quarterly)  consists of .15% of the average  daily net asset value of the Fund's
shares sold by authorized institutions.

Acquiring  Class B Shares.  Class B shares are  acquired  at net asset value per
share without an initial sales charge only in exchange for "B Exchanged Shares",
i.e. shares of the same class of another Lord Abbett-sponsored fund used in such
exchange.  See "Shareholder  Services -- Telephone Exchanges" below. However, if
Class B shares are redeemed for cash before the sixth anniversary of the initial
purchase of B  Exchanged  Shares,  a CDSC  normally  will be  deducted  from the
redemption proceeds.  The charge will be assessed on the lesser of the net asset
value of the shares at the time of  redemption or the original  purchase  price.
The CDSC is not imposed on the amount of your account value  represented  by the
increase in net asset value over the initial purchase price (including increases
due to the  reinvestment of dividends).  The Class B CDSC is paid to Lord Abbett
Distributor  to  reimburse  part  of  its  expenses  associated  with  providing
distribution-related services to the Fund in connection with the distribution of
Class B shares.

To determine  whether the CDSC applies to a redemption,  the Fund redeems shares
in the following  order:  (1) shares  acquired by  reinvestment of dividends (2)
shares held until the sixth  anniversary of their initial purchase or later, and
(3) shares  held the  longest  before  the sixth  anniversary  of their  initial
purchase.

The amount of the CDSC will depend on the number of years since you invested and
the dollar amount being redeemed, according to the following schedule.

Anniversary
of the Day on                 Contingent Deferred
Which the Purchase            Sales Charge on
Order Was Accepted            Redemptions
                              (As % of Amount
On      Before                Subject to Charge)
        1st                   5.0%
1st     2nd                   4.0%
2nd     3rd                   3.0%
3rd     4th                   3.0%
4th     5th                   2.0%
5th     6th                   1.0%
on or after the               None
6th anniversary

In the table,  an  "anniversary"  is the 365th day subsequent to a purchase or a
prior  anniversary.  All  purchases  are  considered  to have  been  made on the
business day the original purchase of B Exchanged Shares was made. See "General"
above.

Waiver of Class B Sales Charges.  The Class B CDSC will not be applied to shares
purchased in certain types of transactions  nor will it apply to shares redeemed
in certain circumstances as described below.
The Class B CDSC will be waived for redemptions of shares (i) in connection with
the  Systematic  Withdrawal  Plan and  Div-Move  services,  as described in more
detail under  "Shareholder  Services" below; (ii) by Retirement Plans due to any
benefit payment such as Plan loans, hardship withdrawals,  death,  retirement or
separation from service with respect to plan participants or the distribution of
any excess contributions,  and (iii) in connection with mandatory  distributions
under 403(b) plans and individual retirement accounts.
<PAGE>

Class B Rule 12b-1  Plan.  The Fund has  adopted a Class B share Rule 12b-1 Plan
(the "B Plan") under which the Fund periodically pays Lord Abbett Distributor an
annual  distribution  fee of 0.75 of 1% of the average  daily net asset value of
the Class B shares that are  outstanding for less than 8 years from the original
purchase date of B Exchanged Shares.

The  0.75%  annual  distribution  fee is  paid  to Lord  Abbett  Distributor  to
compensate it for its services  rendered in connection with the  distribution of
Class B shares,  including the payment and financing of sales  commissions  on B
Exchanged Shares. Lord Abbett Distributor pays an up-front payment to authorized
institutions  totalling 4% with  respect to B Exchanged  Shares,  consisting  of
0.25% for service and 3.75% for a sales commission as described below. Under the
Rule 12b-1 Plans  ("other  Plans") of other Lord  Abbett-sponsored  funds,  Lord
Abbett  Distributor  pays the 0.25%  service fee to authorized  institutions  in
advance  for the  first  year  after B  Exchanged  Shares  have been sold by the
authorized institutions. After the shares have been held for a year, Lord Abbett
Distributor pays the service fee on a quarterly basis.  Lord Abbett  Distributor
is  entitled  to retain  such  service  fee  payable  under the other Plans with
respect to accounts for which there is no  authorized  institution  of record or
for which such authorized institution did not qualify.

Although  B  Exchanged   Shares  sold   directly  to  investors  by  other  Lord
Abbett-sponsored  funds are sold without a front-end  sales charge,  Lord Abbett
Distributor  pays authorized  institutions  responsible for sales of B Exchanged
Shares a sales  commission of 3.75% of the purchase price.  This payment is made
at the time of sale from Lord Abbett  Distributor's  own resources.  Lord Abbett
Distributor has made  arrangements to finance these commission  payments,  which
arrangements include non-recourse  assignments by Lord Abbett Distributor to the
financing  party of such  distribution  and CDSC payments which are made to Lord
Abbett  Distributor by  shareholders  who redeem their Class B shares within six
years of the initial purchase of B Exchanged Shares.

The  distribution  fee and the CDSC payments  described above allow investors to
acquire  Class B  shares  with B  Exchanged  Shares.  The  CDSC is  intended  to
supplement Lord Abbett  Distributor's  reimbursement for the commission payments
it has made with respect to B Exchanged Shares and its related  distribution and
financing  costs. The distribution fee payments are at a fixed rate and the CDSC
payments are of a nature that, during any year, both forms of payment may not be
sufficient to reimburse Lord Abbett  Distributor  for its actual  expenses.  The
Fund is not liable for any  expenses  incurred  by Lord  Abbett  Distributor  in
excess of (i) the amount of such  distribution  fee  payments  to be received by
Lord Abbett  Distributor  and (ii)  unreimbursed  distribution  expenses of Lord
Abbett  Distributor  incurred in a prior plan year,  subject to the right of the
Board of Directors or  shareholders  to terminate the B Plan. Over the long-term
the expenses  incurred by Lord Abbett  Distributor are likely to be greater than
such  distribution  fee  and  CDSC  payments.   Nevertheless,   there  exists  a
possibility  that for a short-term  period Lord Abbett  Distributor may not have
sufficient expenses to warrant reimbursement by receipt of such distribution fee
payments. Although Lord Abbett Distributor undertakes not to make a profit under
the B Plan,  the B Plan is considered a  compensation  plan (i.e.,  distribution
fees are paid regardless of expenses incurred) in order to avoid the possibility
of Lord Abbett  Distributor not being able to receive  distribution fees because
of a temporary timing difference  between its incurring  expenses and receipt of
such distribution fees.

Automatic  Conversion  of Class B  Shares.  On the  eighth  anniversary  of your
original purchase of B Exchanged Shares,  your Class B shares will automatically
convert to Class A shares.  This conversion relieves Class B shareholders of the
higher annual  distribution fee that applies to Class B shares under the Class B
Rule 12b-1 Plan.  The conversion is based on the relative net asset value of the
two classes, and no sales charge or other charge is imposed. When Class B shares
convert,  any other Class B shares that were  acquired  by the  reinvestment  of
dividends will also convert to

Class A shares on a pro rata  basis.  The  conversion  feature is subject to the
continued  availability of an opinion of counsel or of a tax ruling described in
"Purchases, Redemptions and Shareholder Services" in the Statement of Additional
Information.

Acquiring  Class C Shares.  Class C shares are  acquired  at net asset value per
share  without a sales charge only in exchange for "C  Exchanged  Shares",  i.e.
shares of the same  class of  another  Lord  Abbett-sponsored  fund used in such
exchange.  See "Shareholder  Services -- Telephone Exchanges" below. However, if
Class C shares are redeemed for cash before the first anniversary of the initial
purchase of C Exchanged  Shares, a CDSC of 1% normally will be deducted from the
redemption proceeds.  The charge will be assessed on the lesser of the net asset
value of the shares at the time of  redemption or the original  purchase  price.
The CDSC is not imposed on the amount of your account value  represented  by the
increase in net asset value over the initial purchase price (including increases
due to the reinvestment of dividends).  The Class C CDSC is paid to the Fund for
remittance to the original Lord  Abbett-sponsored fund to reimburse it, in whole
or in part, for the service and  distribution fee payments made by that original
fund.

To determine  whether the CDSC applies to a redemption,  the Fund redeems shares
in the following  order:  (1) shares acquired by reinvestment of dividends,  (2)
shares held for one year or more,  and (3) shares  held the  longest  before the
first  anniversary  of their initial  purchase.  If Class C shares are exchanged
into the same  class of  another  Lord  Abbett-sponsored  fund and  subsequently
redeemed before the first anniversary of their original purchase,  the CDSC will
be  collected by the other fund on behalf of the  original  fund.  The Fund will
collect  such a charge  for  other  Lord  Abbett-sponsored  funds  in a  similar
situation.

Class C Rule 12b-1 Plan. The service fees described  below are not being paid by
the Fund and have not been paid since July 12, 1996,  the effective  date of the
Class C share Rule 12b-1  Plan (the "C Plan").  Under the C Plan,  (except as to
certain accounts for which tracking data is not available) the Fund is permitted
to pay authorized institutions through Lord Abbett Distributor (1) a service fee
at the time shares are sold,  not to exceed 0.25 of 1% of the net asset value of
such shares and (2) at each quarter-end  after the first anniversary of the sale
of shares,  fees for  services  at annual  rates not to exceed 0.25 of 1% of the
average annual net asset value of such shares outstanding (payments with respect
to shares not outstanding during the full quarter to be prorated). These service
fees are for  purposes  similar to those  mentioned  above with respect to the A
Plan.  Sales in clause (1) exclude  shares issued for  reinvested  dividends and
shares outstanding in clause (2) include shares issued for reinvested  dividends
after the first anniversary of their issuance.  Collection of CDSCs by the Fund.
The Fund is currently collecting CDSCs on behalf of other Lord  Abbett-sponsored
funds with  operating  12b-1 plans even though the Fund is currently  not making
service fee payments under its own A Plan or C Plan. The timing,  categories and
calculation  of this charge may be changed by vote  (including  a  disinterested
directors' vote) of the Boards of Directors of such other funds.  Redemptions of
Fund shares in exchange for another Lord  Abbett-sponsored  fund (see "Telephone
Exchange Privilege" under "Shareholder Services") or by participants in

Retirement  Plans  due to any  benefit  payment,  such as plan  loans,  hardship
withdrawals, death, retirement or separation from service or the distribution of
any excess contributions are excluded from the CDSCs mentioned above in the case
of Class A and Class B shares but not in the case of Class C shares.

7    DIVIDENDS, YIELD AND TAXES

Dividends: On each day that the New York Stock Exchange is open for trading, our
net income will be declared  as a dividend  to  shareholders  of record as of 12
noon (New York time) that day. Unless you elect to receive cash,  dividends will
be reinvested in additional shares on the monthly reinvestment date.

If you  elect a cash  payment,  (i) a check  will  be  mailed  to you as soon as
possible after the monthly  reinvestment date or (ii) if you arranged for direct
deposit, your payment will be wired directly to your bank account within one day
after the  payable  date.  If you redeem  your  entire  account,  all  dividends
declared to the effective time of redemption will be paid to you.  Dividends and
distributions  declared  in  October,  November  or December of any year will be
treated for federal income tax purposes as having been received by  shareholders
in that year if they are paid before February 1 of the following year.

Yield:  For the  seven-day  period  ending  June  30,  1995,  our  Class A share
annualized yield was 4.96% and the compounded effective yield was 5.09%. On that
date our portfolio  had a  dollar-weighted  life to maturity of 29.5 days.  From
time to time,  the Fund may advertise its "yield" and  "effective  yield".  Both
yield figures are based on historical  earnings and are not intended to indicate
future  performance.  It  can be  expected  that  these  yields  will  fluctuate
substantially.  The  "yield" of the Fund  refers to the income  generated  by an
investment  in the Fund over a seven-day  period (which period will be stated in
any  advertisement).  This income is then  "annualized".  That is, the amount of
income  generated by the investment  during that week is assumed to be generated
each week 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 Fund is assumed to be reinvested.  The "effective
yield" will be  slightly  higher  than the  "yield"  because of the  compounding
effect of this assumed reinvestment.
<PAGE>

Yield  information is useful in reviewing the Fund's  performance  but,  because
yields will fluctuate,  such  information may not provide a basis for comparison
with domestic bank deposits and other  investments which pay a fixed yield for a
stated period of time or other  investment  companies  which may use a different
method of computing yield.

Taxes:  We intend to continue to qualify  under the  Internal  Revenue Code as a
regulated  investment company. We will try to distribute to shareholders all our
taxable  income,  so as to avoid the necessity of the Fund paying federal income
tax.  Dividends,  whether  received in cash or reinvested in additional  shares,
will generally be treated as ordinary income to shareholders  for federal income
tax purposes.

Shareholders may be subject to a $50 penalty under the Internal Revenue Code and
we may be required to withhold and remit to the U.S. Treasury a portion (31%) of
any redemption  proceeds  (including the value of shares  exchanged into another
Lord Abbett-sponsored fund), and of any dividend or distribution on any account,
where  the  payee   (shareholder)   failed   to   provide  a  correct   taxpayer
identification  number  or to make  certain  required  certifications.  For more
details, see the Application Form.

We will  inform  shareholders  of the federal  tax status of each  dividend  and
distribution  after the end of each calendar year.  Shareholders  should consult
their tax advisers  concerning  applicable  state and local taxes as well as the
tax  consequences  of gains or losses  from the  redemption  or  exchange of our
shares.

8    REDEMPTIONS

We will redeem  shares at our net asset value next  determined  after receipt by
the Fund of a redemption  request in the form described below. If you redeem all
of your shares,  you will receive,  in addition to the net asset value  thereof,
all declared but unpaid dividends.  You may elect to use either the expedited or
regular  redemption  procedures  or to redeem by check.  If either the expedited
procedure  or  checkwriting  has been  elected,  no stock  certificates  will be
issued.  The  expedited  procedure  and  checkwriting  may not be used to redeem
shares  purchased by check until 15 days after  acceptance of the order,  or, in
the case of checks drawn on banks located  outside of the United  States,  until
the Fund determines that the check has cleared. Redemption requests with payment
to be made by check will be accepted as of 2 P.M.  (New York time) on the day of
receipt so that you will receive that day's dividend.  Redemption  requests with
payment to be made by wire transfer will be effected at the last  determined net
asset  value and you will not earn the  dividend  declared on the day shares are
redeemed by wire if such a request is received prior to 12 noon (New York time).

Checkwriting.  The Fund will provide  you,  upon  request,  with forms of checks
drawn on the United  Missouri  Bank of Kansas City,  N.A.  (the  "Bank").  These
checks may be made payable to any person in any amount of not less than $500 nor
more than  $5,000,000.  When such a check is  presented to the Bank for payment,
the Bank, as your agent,  will request the Fund to redeem a sufficient number of
full and  fractional  shares in your  account  to cover the amount of the check.
Shares (full and  fractional)  in an account of a different  class than those in
the  account  on which the check is drawn  will not be  redeemed  to cover  such
check.  You will continue  earning daily  dividends until the check has cleared.
You will be subject to all applicable Bank rules and  regulations  including the
right of the Bank not to honor  checks  in  amounts  exceeding  the value of the
account at the time the check is presented for payment, even though you may have
another  account with  sufficient  value in your name on which the check was not
written.  You do not establish a checking or other account with the Bank for the
purpose of FDIC federal  deposit  insurance or otherwise when you participate in
this  checkwriting  privilege.  The Fund and the Bank each reserves the right to
modify or terminate this service at any time. Checks should not be used to close
your account since your account earns dividends until the check clears,  and the
amount in your account, including accrued dividends, may not equal the amount of
the check.

Expedited Procedure.  Under the expedited procedure, you should designate on the
Application  Form an account  at a domestic  bank.  Thereafter,  the  redemption
proceeds  normally will be  transmitted  by wire  (minimum  $1,000) or mailed by
check to the  designated  account on the next business day following  receipt of
the request,  except that if a redemption  request for wire transfer is received
prior to 12 noon (New York time), the redemption proceeds normally will be wired
that day and shares so redeemed will not earn that day's dividend. The Fund will
not be liable for  following  instructions  communicated  by  telephone  that it
reasonably  believes  to be genuine  and will employ  reasonable  procedures  to
confirm that  instructions  received are genuine,  including  requesting  proper
identification and recording all telephone  redemptions and mailing the proceeds
only  to  the  named  shareholder  at  the  address  appearing  on  the  account
registration.

We reserve  the right to increase  the minimum  that may be wired or to impose a
reasonable charge for this service. You may transmit a redemption request to the
Fund by  telephone  (call  the  Fund  at  800-821-5129  and  ask for  "Expedited
Redemptions -- Lord Abbett U.S. Government  Securities Money Market Fund") or in
writing. In order to use the expedited  procedure,  all redemption proceeds must
be paid to the same bank and account as designated on the  Application  Form. To
change  the bank or  account  you must send a written  request  to the Fund with
signature(s) guaranteed as described below.

Regular  Procedure.  You must submit a written redemption request to the Fund in
proper form.  See  "Purchases"  for a description  of when a redemption  request
(order) is in proper form. Normally, payment will be made by check mailed within
one business day after receipt of a redemption request in proper form,  although
we reserve the right to make such payment within three  business days.  General.
Within three days after acceptance of a redemption  request,  we make payment in
cash  except  that  payment  may be delayed  until  checks  received  for shares
purchased have cleared.  In addition,  we may suspend the right of redemption or
delay  payment  more than three days  during any period  when the New York Stock
Exchange is closed  (other than  customary  weekend or holiday  closings)  or an
emergency exists as determined by the Securities and Exchange Commission ("SEC")
so that disposal of our investments or  determination  of our net asset value is
not reasonably practicable,  or for such other periods as the SEC, by order, may
permit for protection of our shareholders.

        Under certain  circumstances  and subject to prior written  notice,  our
Board of Directors may authorize  redemption of all of the shares in any account
in which there are fewer than 500 shares.

9    OUR MANAGEMENT

Our business is managed by our officers on a day-to-day  basis under the overall
direction  of our Board of Directors  with the advice of Lord Abbett.  We employ
Lord Abbett as  investment  manager  pursuant to a  Management  Agreement.  Lord
Abbett has been an investment  manager for over 65 years and  currently  manages
over $19 billion in a family of mutual funds and other advisory accounts.  Under
the Management  Agreement,  Lord Abbett provides us with  investment  management
services  and  executive  and  other  personnel,  pays the  remuneration  of our
officers and our directors affiliated with Lord Abbett,  provides us with office
space and pays for ordinary and necessary office and clerical  expenses relating
to research, statistical work and supervision of our portfolio and certain other
costs.   Lord  Abbett   provides   similar   services   to  twelve   other  Lord
Abbett-sponsored  funds having  various  investment  objectives and also advises
other  investment  clients.  David Seto,  Executive  Vice  President,  serves as
portfolio manager of the Fund and has done so since March 1992. Prior to joining
Lord  Abbett,  Mr.  Seto  was  a  portfolio  manager  for  Lexington  Management
Corporation.

        Under the  Management  Agreement,  we are obligated to pay Lord Abbett a
monthly fee,  based on average  daily net assets for each month.  For the fiscal
year ended June 30, 1995, the fee paid to Lord Abbett as a percentage of average
daily net assets was at the annual rate of .50 of 1%. Our Class A share ratio of
expenses,  including  management  fee  expenses,  to average net assets for this
fiscal year was .86%.

10   SHAREHOLDER SERVICES

We offer the following shareholder services:
Telephone Exchange  Privilege:  Shares of any class may be exchanged,  without a
service   charge,   (a)  for  shares  of  the  same  class  of  any  other  Lord
Abbett-sponsored  fund except for (i) Lord  Abbett  Equity  Fund  ("LAEF"),  any
Series of Lord Abbett  Research  Fund,  Inc.  not offered to the general  public
("LARF") and Lord Abbett Series Fund,  Inc.  ("LASF") and (ii) certain  tax-free
single-state series where the exchanging shareholder is a resident of a state in
which such series is not  offered for sale and (b) for shares of any  authorized
institution's affiliated money market fund satisfying Lord Abbett Distributor as
to certain  omnibus  account and other criteria  (together,  "Eligible  Funds").
Class A Shares purchased directly from the Fund may be exchanged only for shares
of the same class of an Eligible Fund. Class B and Class C shares, which may not
be purchased  directly from the Fund,  may be acquired in exchange for shares of
the same class of any  Eligible  Fund.  You or your  representative  with proper
identification can instruct the Fund to exchange  uncertificated shares (held by
the transfer agent) by telephone.  Shareholders  have this privilege unless they
refuse it in  writing.  The Fund will not be liable for  following  instructions
communicated  by telephone  that it  reasonably  believes to be genuine and will
employ reasonable  procedures to confirm that instructions received are genuine,
including   requesting  proper   identification   and  recording  all  telephone
exchanges.

Exchanges  for shares of any  Eligible  Fund will be based on the  relative  net
asset values of the shares  exchanged,  without a sales charge in most cases.  A
sales charge,  however,  will be payable on exchanges for shares of any Eligible
Fund in the Lord Abbett  Family of Funds in  accordance  with the  prospectus of
that  fund if the  shares  being  exchanged  are in Class A and  were  purchased
directly from the Fund (not including shares described under "Div-Move"  below).
Instructions must be received by the Fund in Kansas City (800-821-5129) prior to
the close of the NYSE to obtain  each  fund's net asset  value per share on that
day. Expedited  exchanges by telephone may be difficult to implement in times of
drastic economic or market change.  The exchange privilege should not be used to
take advantage of short-term  swings in the market.  The Fund reserves the right
to  terminate  or limit the  privilege  of any  shareholder  who makes  frequent
exchanges.  The Fund can revoke the privilege for all shareholders upon 60 days'
prior written  notice.  A prospectus  for the other Lord  Abbett-sponsored  fund
selected by you should be obtained and read before an exchange.  Exercise of the
Exchange  Privilege  will be treated as a sale for federal  income tax  purposes
and, depending on the  circumstances,  a capital gain or loss may be recognized.
Systematic Withdrawal Plan ("SWP"):  Except for Retirement Plans for which there
is no such minimum, if the offering price value of your uncertificated shares is
at least $10,000,  you may have periodic cash withdrawals  automatically paid to
you in either fixed or variable  amounts.  With  respect to Class B shares,  the
CDSC will be waived on  redemptions  of up to 12% per year of either the current
net asset value of your account or your original  purchase  price,  whichever is
higher. For Class B shares (over 12% per year) and C shares, redemption proceeds
due to a SWP will be derived from the following sources in the order listed: (1)
shares acquired by  reinvestment of dividends,  (2) shares held for six years or
more  (Class B) or one year or more  (Class C); and (3) shares  held the longest
before the sixth  anniversary of their initial  purchase (Class B) or before the
first  anniversary of their initial purchase (Class C).  Shareholders  should be
careful in  establishing a SWP,  especially to the extent that such a withdrawal
exceeds the annual total return for a class,  in which case,  the  shareholder's
original principal will be invaded and, over time, may be depleted.
<PAGE>

Div-Move:  You can  invest  the  dividends  paid on your  account  ($50  minimum
investment)  into an existing  account in any other  Eligible  Fund. The account
must be either your account,  a joint account for you and your spouse,  a single
account for your spouse,  or a custodial  account for your minor child under the
age of 21.  Such  dividends  are not  subject  to a CDSC.  You  should  read the
prospectus of the other fund before investing.

Invest-A-Matic:   You  can  make  fixed,   periodic   investments  ($50  minimum
investment)  into an existing account in any Eligible Fund by means of automatic
money transfers from your bank checking account.  You should read the prospectus
of the other fund before investing.

Retirement  Plans:  Lord Abbett makes  available the  retirement  plan forms and
custodial  agreements  for  IRAs  (Individual  Retirement  Accounts,   including
Simplified  Employee  Pensions),  403(b)  plans and pension  and  profit-sharing
plans, including 401(k) plans.

Householding:  A single copy of an annual or semi-annual  report will be sent to
an address to which more than one  registered  shareholder  of the Fund with the
same last name has indicated mail is to be delivered,  unless additional reports
are specifically requested in writing or by telephone.

All correspondence  should be directed to Lord Abbett U.S. Government Securities
Money  Market  Fund,  Inc.  (P.O.  Box  419100,  Kansas  City,  Missouri  64141;
800-821-5129).

LORD ABBETT

Statement of Additional Information                              July 15, 1996


                                   Lord Abbett
                           U.S. Government Securities
                             Money Market Fund, Inc.



This Statement of Additional  Information is not a Prospectus.  A Prospectus may
be obtained from Lord Abbett Distributor LLC ("Lord Abbett  Distributor") at The
General Motors Building,  767 Fifth Avenue, New York, New York 10153-0203.  This
Statement  relates to, and should be read in  conjunction  with,  the Prospectus
dated July 15, 1996.

 As of July 12, 1996, Lord Abbett U.S. Government  Securities Money Market Fund,
Inc. (sometimes  referred to as "we" or the "Fund") had 1,000,000,000  shares of
authorized  capital  stock  consisting  of three classes (A, B and C), $.001 par
value. The Board of Directors will allocate these  authorized  shares of capital
stock among the classes from time to time.  Prior to July 12,  1996,  we had one
class of shares, which is now designated Class A. The Class B and Class C shares
will be offered  to the  public  for the first time on or about  August 1, 1996.
Only Class A shares may be purchased  directly or acquired by exchange.  Class B
and Class C shares may be acquired  only by exchange.  See  "Telephone  Exchange
Privilege"  for more  information.  All shares have equal  noncumulative  voting
rights and equal  rights  with  respect to  dividends,  assets and  liquidation,
except  for   certain   class-specific   expenses.   They  are  fully  paid  and
nonassessable when issued and have no preemptive or conversion rights.

Rule 18f-2 under the Act provides that any matter  required to be submitted,  by
the provisions of the Act or applicable  state law or otherwise,  to the holders
of the outstanding  voting securities of an investment  company such as the Fund
shall not be deemed to have been  effectively  acted upon unless approved by the
holders of a majority of the  outstanding  shares of each class affected by such
matter.  Rule 18f-2 further provides that a class shall be deemed to be affected
by a matter unless the  interests of each class in the matter are  substantially
identical or the matter does not affect any interest of such class. However, the
Rule exempts the selection of independent  public  accountants,  the approval of
principal distributing contracts and the election of directors from its separate
voting requirements.

                        Investment Objective and Policies

Fundamental Investment Restrictions
- -----------------------------------
The Fund may not:  (1) borrow  money,  except  that (i) the Fund may borrow from
banks (as defined in the Investment Company Act of 1940, as amended (the "Act"))
in amounts up to 33 1/3% of its total assets  (including  the amount  borrowed),
(ii) the  Fund  may  borrow  up to an  additional  5% of its  total  assets  for
temporary  purposes,  (iii) the Fund may obtain such short-term credit as may be
necessary for the clearance of purchases and sales of portfolio  securities  and
(iv) the Fund may  purchase  securities  on margin to the  extent  permitted  by
applicable  law; (2) pledge its assets (other than to secure  borrowings,  or to
the  extent  permitted  by  the  Fund's  investment  policies  as  permitted  by
applicable law); (3) engage in the  underwriting of securities,  except pursuant
to a merger  or  acquisition  or to the  extent  that,  in  connection  with the
disposition of its portfolio  securities,  it may be deemed to be an underwriter
under federal securities laws; (4) make loans to other persons,  except that the
acquisition  of  bonds,  debentures  or  other  corporate  debt  securities  and
investment   in   government   obligations,   commercial   paper,   pass-through
instruments, certificates of deposit, bankers acceptances, repurchase agreements
or any similar  instruments shall not be subject to this limitation,  and except
further  that the Fund may lend  its  portfolio  securities,  provided  that the
lending of portfolio  securities may be made only in accordance  with applicable
law;  (5) buy or  sell  real  estate,  although  the  Fund  may  buy  short-term
securities secured by real estate or interests  therein,  or issued by companies
which invest in real estate or interests  therein,  nor may the Fund buy or sell
commodities  or commodity  contracts,  interests  in oil,  gas or other  mineral
exploration or development programs; (6) with respect to 75% of the gross assets
of the Fund,  buy  securities  of one  issuer  representing  more than 5% of the
Fund's  gross  assets,  except  securities  issued  or  guaranteed  by the  U.S.
Government,  its agencies or instrumentalities;  (7) invest more than 25% of its
assets,  taken at market value,  in the  securities of issuers in any particular
industry  (excluding  U.S.  Government  securities  as  described  in the Fund's
prospectus);  (8) issue  senior  securities  to the extent such  issuance  would
violate applicable law; or (9) buy common stocks or other voting securities.

With respect to the restrictions mentioned herein, compliance therewith will not
be affected by changes in the market value of portfolio  securities  but will be
determined at the time of purchase or sale of such securities.

Non-Fundamental   Investment   Restrictions.   In  addition  to  the  investment
- -------------------------------------------
restrictions above which cannot be changed without shareholder approval, we also
are subject to the following  non-fundamental  investment  policies which may be
changed by the Board of Directors  without  shareholder  approval.  The Fund may
not:  (1)  borrow in excess  of 5% of its gross  assets  taken at cost or market
value, whichever is lower at the time of borrowing, and then only as a temporary
measure  for  extraordinary  or  emergency  purposes;  (2) make  short  sales of
securities  or  maintain  a short  position  except to the extent  permitted  by
applicable  law;  (3) invest  knowingly  more than 15% of its net assets (at the
time of investment) in illiquid securities, except for securities qualifying for
resale under Rule 144A of the Securities Act of 1933, deemed to be liquid by the
Board of Directors;  (4) invest in the securities of other investment  companies
except as  permitted by  applicable  law;  (5) invest in  securities  of issuers
which,  with  their  predecessors,  have a  record  of less  than  three  years'
continuous  operations,  if more than 5% of the  Fund's  total  assets  would be
invested   in  such   securities   (this   restriction   shall   not   apply  to
mortgaged-backed  securities,  asset-backed  securities or obligations issued or
guaranteed by the U. S. Government, its agencies or instrumentalities); (6) hold
securities of any issuer if more than 1/2 of 1% of the securities of such issuer
are owned  beneficially  by one or more  officers or directors of the Fund or by
one or more partners or members of the Fund's  underwriter or investment adviser
if these owners in the aggregate own beneficially more than 5% of the securities
of such issuer;  (7) invest in warrants if, at the time of the acquisition,  its
investment in warrants,  valued at the lower of cost or market,  would exceed 5%
of the Fund's total assets (included  within such limitation,  but not to exceed
2% of the Fund's total assets, are warrants which are not listed on the New York
or American Stock Exchange or a major foreign exchange);  (8) write, purchase or
sell puts,  calls,  straddles,  spreads or combinations  thereof,  except to the
extent   permitted  in  the  Fund's   prospectus  and  statement  of  additional
information,  as they may be amended from time to time;  or (9) buy from or sell
to any of its officers,  directors,  employees, or its investment adviser or any
of its officers,  directors,  partners or employees,  any securities  other than
shares of the Fund's common stock.
                                       2

<PAGE>

Direct U.S.  Government  obligations are issued by the U.S. Treasury and include
bills,  certificates of indebtedness,  notes and bonds. U.S. agency  obligations
are issued by agencies  established  under the  authority  of an act of Congress
including,  but not limited  to, the Bank for  Cooperatives,  Federal  Home Loan
Banks and Federal Intermediate Credit Banks.

Certificates  of deposit  are  certificates  issued in  consideration  for funds
deposited  in a bank or savings  and loan  association.  They are for a definite
period of time,  earn a specified  rate of return and are  negotiable.  Banker's
acceptances  are  short-term  credit  instruments  primarily used to finance the
import, export,  transfer or storage of goods. They are termed "accepted" when a
bank guarantees their payment at maturity.

Variable  amount  master  demand  notes are demand  obligations  that permit the
investment of fluctuating  amounts at varying market rates of interest  pursuant
to arrangements between the issuer and a commercial bank acting as agent for the
payees  of such  notes;  each  party  has the  right to vary the  amount  of the
outstanding indebtedness of the notes.

REPURCHASE  AGREEMENTS.  A repurchase agreement is an instrument under which the
purchaser  (i.e.,  the Fund)  acquires the  obligation  (debt  security) and the
seller  agrees,  at the time of the sale,  to  repurchase  the  obligation  at a
mutually agreed upon time and repurchase  price,  thereby  determining the yield
during the purchaser's  holding  period.  This results in a fixed rate of return
insulated from market fluctuation during such period. The underlying  securities
will consist only of securities in which we may otherwise invest and their value
will be marked to market  daily to ensure  that such value is at least  equal to
the repurchase price (including accrued interest). Repurchase agreements usually
are for  short  periods.  In the event of  bankruptcy  or other  default  by the
seller,  we would be subject to  possible  risks such as delays and  expenses in
liquidating  the  underlying  securities,  decline  in value  of the  underlying
securities and loss of interest. To minimize any such risk, the creditworthiness
of entities with whom we enter into repurchase agreements is carefully evaluated
by our investment manager, Lord Abbett.


                                       2.
                                Yield Calculation

Each Class  calculates its "yield" and "effective  yield" based on the number of
days in the period  for which the  calculation  is made  ("base  period").  Each
Class'  "yield" is  computed by  determining  the net change for the base period
(exclusive  of  capital  changes)  in the  value of a  hypothetical  preexisting
account  having a  balance  of one  share at the  start of the base  period  and
subtracting  this  value  from the value of the  account  at the end of the base
period and dividing the result by the account's  beginning value to come up with
a "base period  return" which is then  multiplied by 365 over the number of days
in the base period.  "Effective  yield" is determined by  compounding  the "base
period return" by adding one, raising the sum to a power equal to 365 divided by
the number of days in the base period and subtracting one from the result. Prior
to July 12, 1996 we had one class of shares which is now designated  Class A. An
example follows for the seven-day  period ended June 30, 1995 of the calculation
of both "yield" and "effective yield" for one Class A share:

Value of hypothetical account with
   exactly one share at beginning of

On June 30, 1995, our portfolio had a  dollar-weighted  life to maturity of 29.5
days.

Publishing of the annualized yield for a given period provides  investors with a
basis for comparing our yield with that of other investment  vehicles.  However,
yields of other  investment  vehicles  may not always be  comparable  because of
different methods of calculating yield. In addition, the safety and yield of the
Fund and other money market funds are a function of portfolio quality, portfolio
maturity and operating expenses, while the yields on competing bank accounts are
established by the bank and their principal is generally insured.

Each Class' yield is not fixed. It fluctuates and the  annualization  of a yield
rate is not a representation  by the Class as to what an investment in the Class
will actually yield for any given period.  Actual yields will depend not only on
changes in interest rates on money market  instruments  during the course of the
period in which the investment in the Class is held, but also on such matters as
any realized  and  unrealized  gains and losses,  changes in the expenses of the
Class during the period and on the relative  amount of new money coming into the
Class which has to be invested at a  different  yield than that  represented  by
existing assets.

1. Outside  directors' fees,  including  attendance fees for board and committee
meetings,  are  allocated  among all Lord  Abbett-sponsored  funds  based on net
assets of each fund. Fees payable by the Fund to its outside directors are being
deferred  under a plan that deems the deferred  amounts to be invested in shares
of the  Fund  for  later  distribution  to the  directors.  The  amounts  of the
aggregate  compensation  payable by the Fund for the fiscal  year ended June 30,
1995 deemed invested in Fund shares,  including dividends reinvested and changes
in net asset value applicable to such deemed investments,  were as follows as of
June 30, 1995: Mr. Bigelow, $419: Mr. Creamer,  $14,914; Mr. Dixon, $20,151; Mr.
Jansing,  $20,836;  Mr. MacDonald,  $8,699; Mr. Millican,  $20,711 and Mr. Neff,
$20,929.

2. Each Lord  Abbett-sponsored fund has a retirement plan providing that outside
directors will receive annual retirement benefits for life equal to 80% of their
final annual retainers following  retirement at or after age 72 with at least 10
years of  service.  Each plan also  provides  for a reduced  benefit  upon early
retirement  under  certain  circumstances,  a  pre-retirement  death benefit and
actuarially  reduced  joint-and-survivor  spousal benefits.  The amounts stated,
except  in the  case of Mr.  Creamer,  would  be  payable  annually  under  such
retirement  plans  if the  director  were to  retire  at age 72 and  the  annual
retainers  payable by such funds  were the same as they are today.  The  amounts
accrued in column 3 were accrued by the Lord  Abbett-sponsored  funds during the
fiscal year ended June 30 , 1995 with  respect to the  retirement  benefits  set
forth in column 4.

3. This column  shows  aggregate  compensation,  including  director's  fees and
attendance  fees for board and committee  meetings,  of a nature  referred to in
footnote one, accrued by the Lord  Abbett-sponsored  funds during the year ended
December 31, 1994.

4. Mr. Bigelow was elected a director of the Fund on October 19, 1994.

5. Mr. Creamer  retired as a director of the Fund effective  September 21, 1994.
The stated  amount of his  retirement  income  (column  4) is the annual  amount
payable  to  him by the  Lord  Abbett-sponsored  funds  before  reduction  for a
joint-and-survivor spousal benefit.

Except where indicated,  the following  executive officers of the Fund have been
associated  with Lord  Abbett for over five  years.  Of the  following,  Messrs.
Allen, Carper,  Cutler,  Henderson,  Morris,  Nordberg and Walsh are partners of
Lord  Abbett;  the others are  employees:  David Seto,  age 35,  Executive  Vice
President,  Kenneth B. Cutler, age 64, Vice President and Secretary;  Stephen I.
Allen,  age 43;  Daniel E. Carper,  age 44;  Robert G. Morris,  age 51, E. Wayne
Nordberg,  age 58; John J. Gargana,  Jr., age 65; Paul A. Hilstad,  age 53 (with
Lord Abbett since 1995;  formerly  Senior Vice President and General  Counsel of
American Capital Management & Research,  Inc.);  Thomas F. Konop, age 54; Victor
W. Pizzolato, age 63; John J. Walsh, age 60, Vice Presidents; and Keith F.
O'Connor, age 41, Treasurer.

The Fund's By-Laws provide that the Fund shall not hold an annual meeting of its
stockholders  in any year unless one or more matters are required to be acted on
by  stockholders  under the Act, as amended (the "Act"),  or unless  called by a
majority  of the Board of  Directors  or by  stockholders  holding  at least one
quarter  of the  stock  of the  Fund  outstanding  and  entitled  to vote at the
meeting.  When any such  annual  meeting is held,  the  stockholders  will elect
directors and vote on the approval of the independent auditors of the Fund.

As of September 30, 1995,  our directors  and officers,  as a group,  owned less
than 1% of our outstanding shares.

                                       4.
                     Investment Advisory and Other Services

As described under "Our Management" in the Prospectus, Lord Abbett is the Fund's
investment  manager.  The eight general partners of Lord Abbett, all of whom are
officers and/or directors of the Fund, are: Stephen I. Allen,  Daniel E. Carper,
Kenneth B. Cutler,  Robert S. Dow,  Thomas S.  Henderson,  Robert G. Morris,  E.
Wayne  Nordberg  and John J. Walsh.  The address of each  partner is The General
Motors Building, 767 Fifth Avenue, New York, New York 10153-0203.

The services  performed by Lord Abbett are described  under "Our  Management" in
the Prospectus. Under the Management Agreement we pay Lord Abbett a monthly fee,
based on average daily net assets for each month, at the annual rate of .5 of 1%
of the  portion of our net assets  not in excess of  $250,000,000,  .45 of 1% of
such assets in excess of $250,000,000  but not in excess of $500,000,000  and .4
of 1% of such assets over $500,000,000. This fee is allocated among Classes A, B
and C based on each class' proportionate share of such average daily net assets.
For the fiscal years ended June 30, 1995,  1994 and 1993,  the  management  fees
attributable  to  Class A  shares  only  and  paid to Lord  Abbett  amounted  to
$775,871, $595,657 and $571,659,  respectively.  For the fiscal years ended 

                                       6

<PAGE>

June 30,  1994 and 1993,  the  management  fees  would have been  $661,762  and,
$694,541,  respectively,  had Lord  Abbett  not  waived a portion of its fee for
those years,  and were  attributable to Class A shares only. Lord Abbett did not
waive a portion of its fee for the fiscal year ended June 30, 1995.

We pay all expenses not  expressly  assumed by Lord Abbett,  including,  without
limitation,  12b-1 expenses,  outside directors' fees and expenses,  association
membership  dues,  legal  and  auditing  fees,  taxes,   transfer  and  dividend
disbursing  agent  fees,  shareholder  servicing  costs,  fees and  expenses  of
registering  our shares under  federal and state  securities  laws,  expenses of
preparing, printing and mailing prospectuses to existing shareholders, insurance
premiums,  brokerage  and other  expenses  connected  with  executing  portfolio
security transactions expenses.

We have  agreed  with  the  State of  California  to  limit  operating  expenses
(including management fees but excluding taxes, interest, extraordinary expenses
and  brokerage  commissions)  to 2 1/2%  of  average  annual  net  assets  up to
$30,000,000, 2% of the next $70,000,000 of such assets and 1 1/2% of such assets
in  excess  of  $100,000,000.  The  expense  limitation  is a  condition  on the
registration of investment  company shares for sale in California and applies so
long as our shares are registered for sale in that State.

Deloitte & Touche LLP, Two World Financial Center, New York, New York 10281, are
the  independent  auditors of the Fund and must be approved at least annually by
our Board of Directors to continue in such capacity. They perform audit services
for the Fund including the examination of financial  statements  included in our
annual report to shareholders.

United  Missouri  Bank of Kansas  City,  N.A.,  Tenth and  Grand,  Kansas  City,
Missouri, is the Fund's custodian.  The custodian pays for and collects proceeds
of  securities  bought  and sold by the Fund and  attends to the  collection  of
principal and income.

                                       5.
                             Portfolio Transactions

We expect that  purchases  and sales of  portfolio  securities  usually  will be
principal transactions. Portfolio securities normally will be purchased directly
from the issuer or from an  underwriter or market maker for the  securities.  We
usually will pay no brokerage  commissions  for such  purchases and no brokerage
commissions  have been paid over the last three  fiscal  years.  Purchases  from
underwriters  of portfolio  securities  will include a commission  or concession
paid by the issuer to the  underwriter  and  purchases  from dealers  serving as
market makers will include a dealer's  markup.  Decisions as to the purchase and
sale of  portfolio  securities  are made by Lord Abbett.  Our  traders,  who are
officers  of the  Fund  and  also  employees  of Lord  Abbett,  implement  these
decisions. They do the trading as well for other accounts--investment  companies
(of which they are also  officers)  and other  clients--managed  by Lord Abbett.
They are responsible for the negotiation of prices and commissions.

Our policy is to have  purchases and sales of portfolio  securities  executed at
the most favorable prices,  considering all costs of the transaction,  including
brokerage  commissions  and  dealer  markups  and  markdowns,   consistent  with
obtaining best execution.  This policy governs the selection of dealers. We make
no  commitments  regarding  the  allocation  of  brokerage  business to or among
broker-dealers.

                                       6.
                          Net Asset Value and Dividends

NET ASSET VALUE.  The  determination  of our net asset value is described  under
"Net Asset Value" in the Prospectus.

As  disclosed in the  Prospectus,  we  calculate  our net asset  value,  declare
dividends  and  otherwise  are open for  business  on each day that the New York
Stock Exchange (the "NYSE") is open for trading. The NYSE is closed on Saturdays
and Sundays and the following  holidays:  New Year's Day,  President's Day, Good
Friday,  Memorial Day,  Independence Day, Labor Day, Thanksgiving and Christmas.
                                       7
<PAGE>

We attempt  to  maintain a net asset  value of $1.00 per share for  purposes  of
sales and  redemptions but there is no assurance that we shall be able to do so.
Although we have received an exemptive  order from the  Securities  and Exchange
Commission  which  permits  us to round  our net  asset  value  per share to the
nearest cent for such purpose,  our Board of Directors has determined that it is
in the best  interests of the Fund and its  shareholders  to value our portfolio
securities under the amortized cost method of securities  valuation  pursuant to
Rule 2a-7 under the  Investment  Company Act of 1940,  as amended (the "Act") so
long as that method  fairly  reflects the Fund's  market-based  net asset value.
Rule 2a-7, as amended,  contains certain maturity,  diversification  and quality
requirements  that apply to any fund  employing  the  amortized  cost  method in
reliance on the Rule and to any registered  investment  company which,  like the
Fund,  holds itself out as a money market fund. (See Prospectus - "How We Invest
- - Rule 2a-7".)

DIVIDENDS.  As described in the Prospectus under  "Dividends,  Yield and Taxes,"
our net income will be declared as a dividend daily.  Net income consists of (1)
all interest income and discount earned  (including  original issue discount and
market discount) less (2) a provision for all expenses, including class-specific
expenses,  plus or  minus  (3) all  short-term  realized  gains  and  losses  on
portfolio assets.

                                       7.
                        Telephone Exchange Privilege and
                                Rule 12b-1 Plans

Telephone Exchange  Privilege.  Shares of the Fund may be exchanged for those in
- -----------------------------
the same class of (a) any other Lord  Abbett-sponsored  fund except for (i) Lord
Abbett Equity Fund ("LAEF"),  Lord Abbett Series Fund ("LASF") and any series of
Lord Abbett  Research Fund not offered to the general  public  ("LARF") and (ii)
certain single-state tax-free series and funds where the exchanging  shareholder
is a resident  of a state in which such  series or fund is not offered for sale,
and (b) any authorized  institution's  affiliated  money market fund  satisfying
Lord  Abbett  Distributor  as to certain  omnibus  account  and other  criteria,
hereinafter  referred to as an "authorized money market fund" or "AMMF". Class B
and Class C shares of the Fund may be acquired  only by  exchange  for shares in
the same class of any eligible Lord Abbett-sponsored fund or AMMF.

You or your representative  with proper  identification can instruct the Fund to
exchange by telephone.  All shareholders  have this privilege unless they refuse
it in  writing.  Exchanges  for  shares in the same class of any  eligible  Lord
Abbett-sponsored  fund or AMMF will be based on the relative net asset values of
the shares exchanged,  without a sales charge in most cases. Only Class A shares
may be purchased  directly from the Fund or acquired by exchange.  Therefore,  a
sales charge will be payable on exchanges for shares of any eligible fund in the
Lord Abbett  Family of Funds in accordance  with the  prospectus of that fund if
the Class A shares being  exchanged were  purchased  directly from the Fund (not
including  shares  described  under  "Div-Move"  below).  Instructions  for  the
exchange  must be  received by the Fund in Kansas City prior to the close of the
NYSE to obtain the other  fund's net asset  value per share  calculated  on that
day.  Securities  dealers may charge for their  services in expediting  exchange
transactions.  Before  making an exchange you should read the  prospectus of the
other  fund  which is  available  from your  securities  dealer  or Lord  Abbett
Distributor. An "exchange" is effected through the redemption of Fund shares and
the  purchase  of  shares  of such  other  Lord  Abbett-sponsored  fund or AMMF.
Exercise of the exchange  privilege will be treated as a sale for federal income
tax purposes, and, depending on the circumstances, a capital gain or loss may be
recognized. This privilege may be modified or terminated at any time.

You should not view the exchange  privilege  as a means for taking  advantage of
short-term  swings in the market and the Fund reserves the right to terminate or
limit the privilege of any shareholder who makes frequent exchanges.

Rule 12b-1  Plans.  The Fund is not making  payments  of Rule 12b-1 fees for its
- -----------------
Class A share  Rule  12b-1 Plan ("A Plan") and its Class C share Rule 12b-1 Plan
("C Plan").  The Fund is making annual  distribution fee payments (0.75 of 1% of
the average daily net asset value of the Class B shares that are outstanding for
less than 8 years) pursuant to its Class B share Rule 12b-1 Plan ("B Plan").  As
described in the Fund's current Prospectus,  the Fund has adopted
                                       8

<PAGE>

a Distribution Plan and Agreement  pursuant to Rule 12b-1 under the Act for each
Class.  In adopting  each Plan and in approving  its  continuance,  the Board of
Directors has  concluded  that based on  information  requested by the Board and
provided by Lord Abbett,  there is a reasonable  likelihood  that each Plan will
benefit the Class and its  shareholders.  The expected  benefits include (in the
case of the Class B Plan) greater sales and lower  redemptions of Class B shares
and (in the  case of the  Class A and C Plan) a higher  quality  of  service  to
shareholders  by dealers than otherwise would be the case. Lord Abbett is to use
all amounts  received  under each Plan for payments to dealers for (i) providing
continuous  services  to each  Class'  shareholders  (in the case of the A and C
Plans),  such as  answering  shareholder  inquiries,  maintaining  records,  and
assisting  shareholders in making redemptions,  transfers,  additional purchases
and exchanges and (ii) their  assistance in distributing  Class B shares (in the
case of the B Plan).

Each Plan  requires  the Board of  Directors  to review,  on a quarterly  basis,
written  reports of all amounts  expended  pursuant to the Plan and the purposes
for which such  expenditures  were made. Each Plan shall continue in effect only
if its  continuance  is  specifically  approved at least annually by vote of the
Board of Directors and of the Fund's directors who are not interested persons of
the Fund and who have no direct or indirect  financial interest in the operation
of the Plan or in any agreements related to the Plan ("outside directors"), cast
in person at a meeting called for the purpose of voting on such Plan.  Each Plan
may not be amended to  increase  materially  the amount  spent for  distribution
expenses  without  approval by a majority of the Fund's  directors,  including a
majority of the outside  directors.  Each Plan may be  terminated at any time by
vote of a majority of the Fund's outside  directors or by vote of the holders of
a majority of each Class' outstanding voting securities.

As stated in the  Prospectus,  a contingent  deferred  sales charge  ("CDSC") is
imposed  with  respect to those shares of the Fund bought in exchange for shares
of another Lord Abbett-sponsored fund or series on which the other fund has paid
a 12b-1 fee if such shares are  redeemed  out of the Fund (a) within a period of
24 months from the end of the month in which the original  sale  occurred in the
case of Class A shares  acquired in  exchange  for shares in the same class of a
fund in the Lord Abbett Family of Funds or (b) within 6 years of their  original
purchase in the case of Class B shares, or (c) within a period of 12 months from
the end of the month in which the original  sale occurred in the case of Class C
shares  acquired in exchange  for shares in the same class of a fund in the Lord
Abbett Family of Funds.

As described in the  Prospectus,  in no event will the amount of the CDSC exceed
1% in the case of Class A and C shares or 5%  scaled  down to 1%, in the case of
Class B shares,  of the lesser of (i) the net asset value of the shares redeemed
or (ii) the  original  cost of the shares for which such shares  were  exchanged
("Exchanged  Shares").  No CDSC will be imposed  when the  investor  redeems (i)
amounts  derived from increases in the value of the account above the total cost
of shares being  redeemed due to increases in net asset value,  (ii) shares with
respect to which no Lord Abbett fund paid a 12b-1 fee (including shares acquired
through  reinvestment  of dividend  income and capital gains  distributions)  or
(iii) shares which,  together with Exchanged Shares, have been held continuously
(a) for 24 months from the end of the month in which the original  sale occurred
in the case of Class A shares,  (b) until the 6th  anniversary of their original
purchase  in the case of Class B shares  and (c)  until the 1st  anniversary  of
their original purchase in the case of Class C shares. In determining  whether a
CDSC is  payable,  (a) shares not  subject to the CDSC will be  redeemed  before
shares subject to the CDSC and (b) of shares  subject to a CDSC,  those held the
longest will be the first to be redeemed.

                                       8.
                    Shareholder Programs and Retirement Plans

We  have  several  programs  available.   These  include  automatic   subsequent
investments of $50 or more from your checking account,  a systematic  withdrawal
plan,  cash  payments  of monthly  dividends  to a  designated  third  party and
expedited exchanges among the Lord  Abbett-sponsored  funds. Forms are available
from the Fund or Lord Abbett.

Under the  Div-Move  service  described  in the  Prospectus,  you can invest the
dividends  paid on your account into an existing  account in any other  Eligible
Fund. The account must be either your account,  a joint account for you and 
                                       9

<PAGE>

your spouse, a single account for your spouse,  or a custodial  account for your
minor  child under the age of 21. You should  read the  prospectus  of the other
fund before investing.

The  Invest-A-Matic  method of investing  in the Fund and/or any other  Eligible
Fund is described in the  Prospectus.  To avail yourself of this method you must
complete  the  application  form,  selecting  the time and  amount  of your bank
checking  account  withdrawals and the funds for  investment,  include a voided,
unsigned check and complete the bank authorization.

The Systematic  Withdrawal Plan (the "SWP") also is described in the Prospectus.
You may  establish a SWP if you own or purchase  uncertificated  shares having a
current  offering  price  value  of at  least  $10,000.  Lord  Abbett  prototype
retirement plans have no such minimum.  The SWP involves the planned  redemption
of shares on a periodic basis by receiving  either fixed or variable  amounts at
periodic  intervals.  With respect to Class B shares, the CDSC will be waived on
redemptions  of up to 12% per year of either the current net asset value of your
account or your original purchase price, whichever is higher. Since the value of
shares  redeemed  may be more or  less  than  their  cost,  gain or loss  may be
recognized for income tax purposes on each periodic payment.  Normally,  you may
not make  regular  investments  at the same  time you are  receiving  systematic
withdrawal  payments because it is not in your interest to pay a sales charge on
new  investments  when in  effect  a  portion  of that  new  investment  is soon
withdrawn.  The minimum investment accepted while a withdrawal plan is in effect
is  $1,000.  The SWP may be  terminated  by you or by us at any time by  written
notice.

The  Prospectus  indicates the types of  retirement  plans for which Lord Abbett
provides forms and explanations. Lord Abbett makes available the retirement plan
forms  and  custodial  agreements  for  IRAs  (Individual   Retirement  Accounts
including Simplified Employee Pensions),  403(b) plans and qualified pension and
profit-sharing plans, including 401(k) plans. The forms name Investors Fiduciary
Trust Company as custodian  and contain  specific  information  about the plans.
Explanations  of  the  eligibility  requirements,   annual  custodial  fees  and
allowable  tax  advantages  and  penalties  are set forth in the  relevant  plan
documents.  Adoption of any of these plans should be on the advice of your legal
counsel or qualified tax adviser.

Our Board of  Directors  may  authorize  redemption  of all of the shares in any
account  in which  there are fewer  than 500  shares.  Before  authorizing  such
redemption, the Board must determine that it is in our economic best interest or
necessary  to  reduce   disproportionately   burdensome  expenses  in  servicing
shareholder  accounts.  At least 60 days'  prior  written  notice  will be given
before any such redemption,  during which time shareholders may avoid redemption
by bringing their accounts up to the minimum set by the Board.

                                       9.
                        Commercial Paper and Bond Ratings

COMMERCIAL PAPER RATINGS

The rating A-1+ is the highest  commercial  paper rating  assigned by Standard &
Poor's Corporation ("S&P"). Paper rated A-1 has the following characteristics:

Liquidity ratio is adequate to meet cash requirements;  long-term senior debt is
rated A or better; the issuer has access to diverse channels of borrowing;  core
earnings  and cash flow have an upward  trend with  allowance  made for  unusual
circumstances;  typically,  the issuer's  industry is well  established  and the
issuer has a strong position within the industry; the reliability and quality of
management are sound.  Those issues  determined to possess  overwhelming  safety
characteristics will be denoted with a plus (+) sign designation.

The  rating P-1 is the  highest  commercial  paper  rating  assigned  by Moody's
Investors Service, Inc. ("Moody's").  Among the factors considered by Moody's in
assigning  ratings are the  following:  (1)  evaluation of the management of the
issuer;  (2) economic  evaluation of the issuer's  industry or industries and an
appraisal of speculative-type  risks which may be inherent in certain areas; (3)
evaluation  of the  issuer's  products in relation to  competition  and customer

                                       10

acceptance;  (4) liquidity;  (5) amount and quality of long-term debt; (6) trend
of earnings over a period of ten years; (7) financial strength of parent company
and the  relationships  which exist with the issuer;  and (8) recognition by the
management  of  obligations  which  may be  present  or may arise as a result of
public interest questions and preparations to meet such obligations.

BOND RATINGS

Moody's Investors Service, Inc.'s Corporate Bond Ratings

Aaa - Bonds  which are rated Aaa are judged to be of the best  quality and carry
the smallest  degree of investment  risk.  Interest  payments are protected by a
large or by an exceptionally  stable margin, and principal is secure.  While the
various  protective  elements  are  likely to  change,  such  changes  as can be
visualized are most unlikely to impair the fundamentally strong position of such
issues.

Aa - Bonds which are rated Aa are judged to be of high-quality by all standards.
Together  with  the Aaa  group,  they  comprise  what  are  generally  known  as
high-grade  bonds.  They are rated lower than the best bonds because  margins of
protection may not be as large as in Aaa  securities,  fluctuation of protective
elements  may be of greater  amplitude  or there may be other  elements  present
which make the long-term risks appear somewhat larger than in Aaa securities.

A - Bonds which are rated A 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 which
suggest a susceptibility to impairment sometime in the future.

Baa - Bonds  which are rated Baa 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.

Ba - Bonds  which are rated Ba are judged to have  speculative  elements;  their
future cannot be considered  as well assured.  Often the  protection of interest
and  principal  payments may be very  moderate and thereby not well  safeguarded
during  both  good  and bad  times  over the  future.  Uncertainty  of  position
characterizes bonds in this class.

B - Bonds  which are  rated B  generally  lack  characteristics  of a  desirable
investment.  Assurance of interest and principal  payments or of maintenance and
other terms of the contract over any long period of time may be small.

Caa - Bonds  that are  rated Caa are of poor  standing.  Such  issues  may be in
default or there may be present  elements of danger with respect to principal or
interest.

Ca - Bonds that are rated Ca represent  obligations  which are  speculative in a
high degree. Such issues are often in default or have other marked shortcomings.

C - Bonds  that are rated C are the  lowest-rated  class of bonds and  issues so
rated can be regarded as having  extremely  poor prospects of ever attaining any
real investment standing.

Standard & Poor's Corporation's Corporate Bond Ratings

AAA - This is the  highest  rating  assigned  by  Standard  &  Poor's  to a debt
obligation  and  indicates an extremely  strong  capacity to pay  principal  and
interest.

AA - Bonds rated AA also qualify as high-quality debt  obligations.  Capacity to
pay principal and interest is very strong and in the majority of instances  they
differ from AAA issues only in small degree.
                                       11

<PAGE>

A - Bonds rated A 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.

BBB - Bonds  rated  BBB are  regarded  as  having an  adequate  capacity  to pay
principal  and  interest.  Whereas they  normally  exhibit  adequate  protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened capacity to pay principal and interest for bonds in
this category than for bonds in the A category.

BB-B-CCC-CC-C  -  Debt  rated  BB,  B,  CCC,  CC  and C is  regarded  as  having
predominately  speculative  characteristics  with  respect  to  capacity  to pay
interest  and  repay  principal.  'BB'  indicates  the  least  degree of
speculation and 'CCC' the highest. While such debt will likely have some
quality  and   protective   characteristics,   these  are  outweighed  by  large
uncertainties or major risk exposures to adverse conditions.

D - Debt  rated  'D'  is in  payment  default.  The  'D'  rating
category is used when  interest  payments or principal  payments are not made on
the date due even if the  applicable  grace period has not  expired,  unless S&P
believes such payments  will be made during such grace period.  The  'D'
rating  also  will be used  upon the  filing of a  bankruptcy  petition  if debt
service payments are jeopardized.

                                       10.
                                      TAXES

The Fund will be subject to a 4% nondeductible excise tax on certain amounts not
distributed  (and not treated as having been  distributed)  on a timely basis in
accordance with a calendar year  distribution  requirement.  The Fund intends to
distribute to shareholders  each year an amount adequate to avoid the imposition
of such excise tax.

Dividends paid by the Fund will not qualify for the dividends-received deduction
for corporations.

                       FURTHER INFORMATION ABOUT THE FUND

The  directors,  trustees and officers of Lord  Abbett-sponsored  mutual  funds,
together  with the partners  and  employees  of Lord  Abbett,  are  permitted to
purchase and sell securities for their personal investment accounts. In engaging
in  personal  securities  transactions,  however,  such  persons  are subject to
requirements  and  restrictions  contained  in the Fund's  Code of Ethics  which
complies,  in  substance,  with each of the  recommendations  of the  Investment
Company Institute's  Advisory Group on Personal  Investing.  Among other things,
the Code  requires  that Lord  Abbett  partners  and  employees  obtain  advance
approval before buying or selling securities, submit confirmations and quarterly
transaction  reports,  and obtain  approval  before  becoming a director  of any
company;  and it  prohibits  such  persons  from  investing in a security 7 days
before or after any Lord  Abbett-sponsored  fund or Lord Abbett-managed  account
considers a trade or trades in such  security,  from  profiting on trades of the
same  security  within  60 days and from  trading  on  material  and  non-public
information.  The Code imposes certain similar  requirements and restrictions on
the independent directors and trustees of each Lord Abbett-sponsored mutual fund
to the extent contemplated by the recommendations of the Advisory Group.

Item 27.          Indemnification

                  Registrant  is  incorporated  under  the laws of the  State of
                  Maryland and is subject to Section  2-418 of the  Corporations
                  and Associations Article of the Annotated Code of the State of
                  Maryland  controlling  the  indemnification  of directors  and
                  officers.  Since  Registrant has its executive  offices in the
                  State of New York,  and is qualified as a foreign  corporation
                  doing  business  in such  State,  the  persons  covered by the
                  foregoing  statute  may also be entitled to and subject to the
                  limitations  of  the  indemnification  provisions  of  Section
                  721-726 of the New York Business Corporation Law.

                  The general effect of these  statutes is to protect  officers,
                  directors and employees of Registrant  against legal liability
                  and expenses  incurred by reason of their  positions  with the
                  Registrant.  The  statutes  provide  for  indemnification  for
                  liability  for  proceedings  not  brought  on  behalf  of  the
                  corporation   and  for   those   brought   on  behalf  of  the
                  corporation,  and in each case place  conditions  under  which
                  indemnification will be permitted, including requirements that
                  the officer,  director or employee acted in good faith.  Under
                  certain  conditions,  payment of  expenses in advance of final
                  disposition  may be  permitted.  The  By-Laws  of  Registrant,
                  without  limiting the authority of Registrant to indemnify any
                  of its officers,  employees or agents to the extent consistent
                  with  applicable  law,  makes  the   indemnification   of  its
                  directors   mandatory  subject  only  to  the  conditions  and
                  limitations  imposed by the  above-mentioned  Section 2-418 of
                  Maryland  Law and by the  provisions  of Section  17(h) of the
                  Investment  Company Act of 1940 as interpreted and required to
                  be  implemented  by SEC Release No.  IC-11330 of  September 4,
                  1980.

                  In referring in its By-Laws to, and making  indemnification of
                  directors  subject to the conditions and  limitations of, both
                  Section  2-418 of the  Maryland  Law and Section  17(h) of the
                  Investment  Company Act of 1940,  Registrant  intends that con
                  ditions and  limitations on the extent of the  indemnification
                  of directors imposed by the provisions of either Section 2-418
                  or  Section  17(h)  shall  apply  and that  any  inconsistency
                  between the two will be resolved by applying the provisions of
                  said Section 17(h) if the  condition or limitation  imposed by
                  Section  17(h)  is the more  stringent.  In  referring  in its
                  By-Laws  to  SEC  Release  No.  IC-11330  as  the  source  for
                  interpretation  and  implementation  of  said  Section  17(h),
                  Registrant  understands  that it would be  required  under its
                  By-Laws  to use  reasonable  and  fair  means  in  determining
                  whether  indemnification  of a  director  should  be made  and
                  undertakes to use either (1) a final decision on the merits by
                  a court or other body before whom the proceeding was brought

                                                         2

                  that  the  person  to be  indemnified  ("indemnitee")  was not
                  liable to Registrant  or to its security  holders by reason of
                  willful malfeasance,  bad faith, gross negligence, or reckless
                  disregard of the duties  involved in the conduct of his office
                  ("disabling  conduct")  or  (2)  in  the  absence  of  such  a
                  decision, a reasonable  determination,  based upon a review of
                  the  facts,  that the  indemnitee  was not liable by reason of
                  such  disabling  conduct,  by (a) the vote of a majority  of a
                  quorum of directors who are neither  "interested  persons" (as
                  defined  in the 1940 Act) of  Registrant  nor  parties  to the
                  proceeding,  or (b) an independent  legal counsel in a written
                  opinion.  Also,  Registrant  will make  advances of attorneys'
                  fees or other  expenses  incurred by a director in his defense
                  only if (in addition to his  undertaking  to repay the advance
                  if he is not ultimately entitled to  indemnification)  (1) the
                  indemnitee  provides  a  security  for  his  undertaking,  (2)
                  Registrant  shall be insured  against losses arising by reason
                  of any lawful  advances,  or (3) a majority of a quorum of the
                  non-interested,  non-party  directors  of  Registrant,  or  an
                  independent   legal  counsel  in  a  written  opinion,   shall
                  determine,  based on a review of readily available facts, that
                  there is reason to believe that the indemnitee ultimately will
                  be found entitled to indemnification.

                  Insofar as  indemnification  for  liability  arising under the
                  Securities Act of 1933 may be permitted to directors, officers
                  and  controlling  persons of the  registrant  pursuant  to the
                  foregoing  provisions,  or otherwise,  the registrant has been
                  advised  that in the opinion of the  Securities  and  Exchange
                  Commission  such  indemnification  is against public policy as
                  expressed in the Act and is, therefore,  unenforceable. In the
                  event   that  a  claim  for   indemnification   against   such
                  liabilities  (other  than the  payment  by the  registrant  of
                  expense incurred or paid by a director, officer or controlling
                  person of the  registrant  in the  successful  defense  of any
                  action,  suit or  proceeding)  is asserted  by such  director,
                  officer  or   controlling   person  in  connection   with  the
                  securities being  registered,  the 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 Act and will be
                  governed by the final adjudication of such issue. In addition,
                  Registrant  maintains a directors'  and  officers'  errors and
                  omissions liability insurance policy protecting  directors and
                  officers against liability for breach of duty,  negligent act,
                  error or omission  committed in their capacity as directors or
                  officers. The policy contains certain exclusions,  among which
                  is exclusion from coverage for active or deliberate  dishonest
                  or  fraudulent  acts and  exclusion  for  fines  or  penalties
                  imposed by law or other matters deemed uninsurable.

                     LORD ABBETT U.S. GOVERNMENT SECURITIES
                            MONEY MARKET FUND, INC.

                             ARTICLES OF AMENDMENT


          LORD ABBETT U.S. GOVERNMENT SECURITIES MONEY MARKET FUND, INC., a
Maryland corporation (hereinafter called the "Corporation"), hereby certifies to
the State Department of Assessments and Taxation of Maryland, that:

          FIRST:  The Articles of Incorporation of the Corporation (hereinafter
called the "Articles"), as heretofore amended, are hereby further amended by:

     (a)  Striking out Section 1 of ARTICLE V and inserting in lieu thereof:

            "SECTION 1. The total number of shares which the Corporation has
     authority to issue is 1,000,000,000 shares of capital stock of the par
     value of $.001 each, having an aggregate par value of $1,000,000. The Board
     of Directors of the Corporation shall have full power and authority, from
     time to time, to classify or reclassify any unissued shares of stock of the
     Corporation, including, without limitation, the power to classify or
     reclassify unissued shares into series, and to classify or reclassify a
     series into one or more classes of stock that may be invested together in
     the common investment portfolio in which the series is invested, by setting
     or changing the preferences, conversion or other rights, voting powers,
     restrictions, limitations as to dividends, qualifications, or terms or
     conditions of redemption of such shares of stock. All shares of stock of a
     series shall represent the same interest in the Corporation and have the
     same preferences, conversion or other rights, voting powers, restrictions,
     limitations as to dividends, qualifications, and terms and conditions of
     redemption as the other shares of stock of that series, except to the
     extent that the Board of Directors provides for differing preferences,
     conversion or other rights, voting powers, restrictions, limitations as to
     dividends, qualifications, or terms or conditions of redemption of shares
     of stock of classes of such series as determined pursuant to Articles
     Supplementary filed for record with the State Department of Assessments and
     Taxation of Maryland, or as otherwise determined pursuant to these Articles
     or by the Board of Directors in accordance with law. Prior to the first
<PAGE>
 
     classification of unissued shares of stock into additional series, all
     outstanding shares of stock shall be of a single series, and prior to the
     first classification of a series into additional classes, all outstanding
     shares of stock of such series shall be of a single class. Notwithstanding
     any other provision of these Articles, upon the first classification of
     unissued shares of stock into additional series, the Board of Directors
     shall specify a legal name for the outstanding series, as well as for the
     new series, in appropriate charter documents filed for record with the
     State Department of Assessments and Taxation of Maryland providing for such
     name change and classification, and upon the first classification of a
     series into additional classes, the Board of Directors shall specify a
     legal name for the outstanding class, as well as for the new class or
     classes, in appropriate charter documents filed for record with the State
     Department of Assessments and Taxation of Maryland providing for such name
     change and classification."

     (b)  Adding a new Section 2 to Article V (and renumbering Sections 2, 3 and
4 as Sections 3, 4 and 5, respectively), as follows:

          "SECTION 2. A description of the relative preferences, conversion and
     other rights, voting powers, restrictions, limitations as to dividends,
     qualifications and terms and conditions of redemption of all series and
     classes of series of shares is as follows, unless otherwise set forth in
     Articles Supplementary filed for record with the State Department of
     Assessments and Taxation of Maryland or otherwise determined pursuant to
     these Articles:

          (a) Assets Belonging to Series.  All consideration received or
              --------------------------                                
              receivable by the Corporation for the issuance or sale of shares
              of a particular series, together with all assets in which such
              consideration is invested or reinvested, all income, earnings,
              profits and proceeds thereof, including any proceeds derived from
              the sale, exchange or liquidation of such assets, and any funds or
              payments derived from any reinvestment of such proceeds in
              whatever form the same may be, shall irrevocably belong to that
              series for all purposes, subject only to the rights of creditors,
              and shall be so recorded upon the books of account of the
              Corporation. Such consideration, assets, income, earnings, profits
              and proceeds, including any proceeds derived from the sale,
              exchange or liquidation




                                       2
<PAGE>
 
              of such assets, and any funds or payments derived from any
              reinvestment of such proceeds in whatever form the same may be,
              together with any unallocated items (as hereinafter defined)
              relating to that series as provided in the following sentence, are
              herein referred to as "assets belonging to" that series. In the
              event that there are any assets, income, earnings, profits or
              proceeds thereof, funds or payments which are not readily
              identifiable as belonging to any particular series (collectively
              "Unallocated Items"), the Board of Directors shall allocate such
              Unallocated Items to and among any one or more of the series
              created from time to time in such manner and on such basis as it,
              in its sole discretion, deems fair and equitable; and any
              Unallocated Items so allocated to a particular series shall belong
              to that series. Each such allocation by the Board of Directors
              shall be conclusive and binding upon the stockholders of all
              series for all purposes.

          (b) Liabilities Belonging to Series.  The assets belonging to each
              -------------------------------                               
              particular series shall be charged with the liabilities of the
              Corporation in respect of that series, including any class
              thereof, and with all expenses, costs, charges and reserves
              attributable to that series, including any such class, and shall
              be so recorded upon the books of account of the Corporation. Such
              liabilities, expenses, costs, charges and reserves, together with
              any unallocated items (as hereinafter defined) relating to that
              series, including any class thereof, as provided in the following
              sentence, so charged to that series, are herein referred to as
              "liabilities belonging to" that series. In the event there are any
              unallocated liabilities, expenses, costs, charges or reserves of
              the Corporation which are not readily identifiable as belonging to
              any particular series (collectively "Unallocated Items"), the
              Board of Directors shall allocate and charge such Unallocated
              Items to and among any one or more of the series created from time
              to time in such manner and on such basis as the Board of Directors
              in its sole discretion deems fair and equitable; and any
              Unallocated Items so allocated and charged to a particular series
              shall belong





                                       3
<PAGE>
 
              to that series. Each such allocation by the Board of Directors
              shall be conclusive and binding upon the stock holders of all
              series for all purposes. To the extent determined by the Board of
              Directors, liabilities and expenses relating solely to a
              particular class (including, without limitation, distribution
              expenses under a Rule 12b-1 plan and administrative expenses under
              an administration or service agreement, plan or other arrangement,
              however designated, which may be adopted for such class) shall be
              allocated to and borne by such class and shall be appropriately
              reflected (in the manner determined by the Board of Directors) in
              the net asset value, dividends and distributions and liquidation
              rights of the shares of such class.

          (c) Dividends.  Dividends and distributions on shares of a particular
              ---------                                                        
              series may be paid to the holders of shares of that series at such
              times, in such manner and from such of the income and capital
              gains, accrued or realized, from the assets belonging to that
              series, after providing for actual and accrued liabilities
              belonging to that series, as the Board of Directors may determine.
              Such dividends and distributions may vary between or among classes
              of a series to reflect differing allocations of liabilities and
              expenses of such series between or among such classes to such
              extent as may be provided in or determined pursuant to Articles
              Supplementary filed for record with the State Department of
              Assessments and Taxation of Maryland or as may otherwise be
              determined by the Board of Directors.

          (d) Liquidation.  In the event of the liquidation or dissolution of
              -----------                                                    
              the Corporation, the stockholders of each series shall be entitled
              to receive, as a series, when and as declared by the Board of
              Directors, the excess of the assets belonging to that series over
              the liabilities belonging to that series. The assets so
              distributable to the stockholders of one or more classes of a
              series shall be distributed among such stockholders in proportion
              to the respective aggregate net asset values of the shares of



                                       4
<PAGE>
 
              such series held by them and recorded on the books of the 
              Corporation.

          (e) Voting.  On each matter submitted to vote of the stockholders,
              ------                                                        
              each holder of a share shall be entitled to one vote for each such
              share standing in his name on the books of the Corporation
              irrespective of the series or class thereof and all shares of all
              series and classes shall vote as a single class ("Single Class
              Voting"); provided, however, that (i) as to any matter with
                                                 -
              respect to which a separate vote of any series or class is
              required by the Investment Company Act of 1940, as amended from
              time to time, applicable rules and regulations thereunder, or the
              Maryland General Corporation Law, such requirement as to a

              class) as may be determined by the Board of Directors, shares of a
              particular class of a series may be automatically converted into
              shares of another class of such series based on the relative net
              asset values of such classes at the time of conversion, subject,
              however, to any conditions of conversion that may be imposed by

     capital stock outstanding in the name of such holder on the books of the
     Corporation, at a redemption price equal to the net asset value of such

     stockholder requiring the Corporation to redeem shares a redemption charge
     not to exceed one percent (1%) of such net asset value or a reimbursement
     charge, a deferred sales charge or other charge that is integral to the
     Corporation's distribution program (which charges may vary within and among

     thereunder, or any other applicable Act of Congress hereafter enacted, and

     (other than an amendment reducing the compensation of the other party
     thereto) shall be effective unless assented to by the affirmative vote of a
     majority of the outstanding voting securities of the Corporation (as such
     phrase is defined in the Investment Company Act of 1940, as amended from
     time to time) entitled to vote on the matter."

     (f)  Striking out the preamble to Section 3 of Article VII and the portion

     Incorporation, the net asset value of shares of the capital stock of the
     Corporation of each series and class as of any particular time (a
     "determination time") shall be determined by or pursuant to the direction
     of the Board of Directors as follows:




                                       6
<PAGE>
 
     (a) At times when a series is not classified into multiple classes, the net
         asset value of each share of stock of a series, as of a determination
         time, shall be the quotient, carried out to not less than two decimal
         points, obtained by dividing the net value of the assets of the
         Corporation belonging to that series (determined as hereinafter
         provided) as of such determination time by the total number of shares
         of that series then outstanding, including all shares of that series
         which the Corporation has agreed to sell for which the price has been
         determined, and excluding shares of that series which the Corporation
         has agreed to purchase or which are subject to redemption for which the
         price has been determined.

         The net value of the assets of the Corporation of a series as of a
         determination time shall be determined in accordance with sound
         accounting practice by deducting from the gross value of the assets of
         the Corporation belonging to that series (determined as hereinafter
         provided), the amount of all liabilities belonging to that series (as
         such terms are defined in subsection (b) of Section 2 of Article V), in
         each case as of such determination time.

         The gross value of the assets of the Corporation belonging to a series
         as of such determination time shall be an amount equal to all cash,
         receivables, the market value of all securities for which market
         quotations are readily available and the fair value of other assets of
         the Corporation belonging to that series (as such terms are defined in
         subsection (a) of Section 2 of Article V) at such determination time,
         all determined in accordance with sound accounting practice and giving
         effect to the following:"

     (g)  Adding a new subsection (b) to Section 3 of Article VII (and
renumbering subsection (b) as subsection (c)), as follows:

         "(b)  At times when a series is classified into multiple classes, the
               net asset value of each share of stock of a class of such series
               shall be determined in accordance with




                                       7
<PAGE>
 
               subsections (a) and (c) of this Section 3 with appropriate
               adjustments to reflect differing allocations of liabilities and
               expenses of such series between or among such classes to such
               extent as may be provided in or determined pursuant to Articles
               Supplementary filed for record with the State Department of
               Assessments and Taxation of Maryland or as may otherwise be
               determined by the Board of Directors."

     (h)  Striking out Section 4 of Article VII and inserting in lieu thereof:

          "SECTION 4.  Any determination as to any of the following matters made
     by or pursuant to the direction of the Board of Directors consistent with
     these Articles of Incorporation and in the absence of willful misfeasance,
     bad faith, gross negligence or reckless disregard of duties, shall be final
     and conclusive and shall be binding upon the Corporation and every holder
     of shares of capital stock of the Corporation, of any series or class,
     namely, the amount of the assets, obligations, liabilities and expenses of
     the Corporation or belonging to any series or with respect to any class;

     for any period and the amount of assets at any time legally available for

     paid-in surplus, other surplus, annual or other net profits, or net assets
     in excess of capital, undivided profits, or excess of profits over losses
     on sales of securities belonging to the Corporation or any series or class;
     the amount, purpose, time of creation, increase or decrease, alteration or
     cancellation of any reserves or charges and the propriety thereof (whether
     or not any obligation or liability for which such reserves or charges shall
     have been created shall have been paid or discharged) with respect to the
     Corporation or any series or class; the market value, or any sale, bid or
     asked price to be applied in determining the market value, of any security
     owned or held by the Corporation; the fair value of any other asset owned
     by the Corporation; the number of shares of stock of any series or class
     issued or issuable; the existence of conditions permitting the postponement
     of payment of the repurchase price of shares of stock of any series or
     class or the suspension of the right of redemption as provided by law; any
     matter relating to the acquisition, holding and disposition of securities
     and other assets by the Corporation; any question as to whether any
     transaction constitutes a purchase of securities on margin, a short sale of
     securities, or an




                                       8

     underwriting of the sale of, or participation in any underwriting or
     selling group in connection with the public distribution of any securities;
     and any matter relating to the issue, sale, repurchase and/or other
