               IT IS THE FUND'S  POLICY TO MAINTAIN,  AND IT HAS  MAINTAINED,  A
          CONSTANT NET ASSET VALUE OF $1.00 PER SHARE. HOWEVER, AN INVESTMENT IN
          THE FUND IS NEITHER INSURED NOR GUARANTEED BY THE U.S.  GOVERNMENT AND
          THERE CAN BE NO  ASSURANCE  THAT WE WILL BE ABLE TO  MAINTAIN A STABLE
          NET ASSET VALUE OF $1.00 PER SHARE.
<PAGE>

HOW WE INVEST

Under normal circumstances, we intend to invest at least 65% of our total assets
in U.S.  GOVERNMENT  SECURITIES,  AGENCIES  AND  INSTRUMENTALITIES  eligible  as
investments  for a money  market  fund.  Up to 35% of our  total  assets  may be
invested in other HIGH-QUALITY, SHORT-TERM SECURITIES.

Our  investments  must meet  certain  portfolio  maturity,  diversification  and
quality  requirements because we are a "money market fund" and use the amortized
cost method of valuing our portfolio securities. See "Net Asset Value."

MATURITY.  The maturity  requirements  limit  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.

DIVERSIFICATION.   Generally  speaking,   with  certain  exceptions,   including
GOVERNMENT SECURITIES, the diversification requirements limit our investments as
follows:  (i) the  securities  of any one issuer are  limited to 5% of our total
assets, (ii) securities issued by or subject to puts from any single institution
are limited to 5% of our total  assets,  and (iii)  securities  that are neither
rated nor  comparable  in quality to  securities  that are rated in the  highest
category are limited to 5% of our total assets.

QUALITY.  We may  invest  only in  securities  that  present  minimal  risks  as
determined by the Board of Directors (or Lord, Abbett & Co. where delegable) and
that satisfy certain requirements  relating to ratings by  nationally-recognized
ratings organizations.

CONCENTRATION.  No  more  than  25% of our  total  assets  may  be  invested  in
securities of any one industry,  except there is no limitation on investments in
obligations  issued  or  backed  by  the  U.S.   GOVERNMENT,   ITS  AGENCIES  OR
INSTRUMENTALITIES.

We may enter into  repurchase  agreements  with Federal  Reserve  member  banks,
primary dealers in U.S.  GOVERNMENT  SECURITIES and  broker-dealers.  Repurchase
agreements must be collateralized by money market securities,  may not exceed 30
days and must be marked daily to the repurchase price.

PORTFOLIO MANAGEMENT

The  Fund's  investment  decisions  are made by  Robert  Gerber.  Mr.  Gerber is
Executive  Vice  President and Portfolio  Manager of the Fund, and has served in
this capacity since the date of this Prospectus.

He joined Lord Abbett in July 1997 as Director of High Grade Fixed Income. Prior
to joining Lord  Abbett,  Mr.  Gerber  served as a Senior  Portfolio  Manager of
Sanford C. Bernstein & Co., Inc. since 1992.

INVESTOR EXPENSES

The expenses  shown below are based on  historical  expenses for the fiscal year
ended June 30, 1997. Future expenses may be greater or less than shown.

Total Operating Expenses                0.84%          1.59%          0.84%

EXAMPLE:  Assume an  average  annual  return of 5% and no change in the level of
expenses.   For  a  $1,000  investment  with  all  dividends  and  distributions
reinvested, you would have paid the following total expenses assuming redemption
at the end of each time period indicated.

Share Class           Year 1    Year 3    Year 5    Year 10
<S>                   <C>       <C>       <C>       <C>   
Class A shares        $ 9       $ 27      $ 47      $ 104
Class B shares(3)     $66       $ 80      $107      $ 169
Class C shares        $19       $ 27      $ 47      $ 104

You  would  pay the  following  expenses  on the same  investment,  assuming  no
redemption:

<S>                   <C>       <C>       <C>       <C>   
Class A shares        $ 9       $ 27      $ 47      $ 104
Class B shares(3)     $16       $ 50      $ 87      $ 169
Class C shares        $ 9       $ 27      $ 47      $ 104
 
This example is for comparison and is not a representation  of the Fund's actual
expenses and returns, either past or present.
<FN>

(1)See "Purchases" for a description of sales charges,  the Contingent  Deferred
Sales Charge  ("CDSC")  payable on certain  redemptions  and separate Rule 12b-1
plans applicable to each class of shares.

(2)Because of the 12b-1 fees,  long-term  shareholders  may  indirectly pay more
than the  equivalent  of the maximum  front-end  sales  charge  permitted by the
National Association of Securities Dealers, Inc. While there are 12b-1 Plans for
Class A and C, they are currently inactive.

(3)Class  B shares  will  automatically  convert to Class A shares on the eighth
anniversary of your original purchase of Class B shares.

PURCHASES

The Fund  offers  three  classes  of  shares,  Class A, B and C. Our  shares are
continuously  offered at their net asset value (normally  $1.00 per share).  You
may  purchase  shares  at the net asset  value  next  determined  after the Fund
accepts your  purchase  order  submitted in proper  form.  Different  classes of
shares represent investments in the same portfolio of securities but are subject
to different expenses and have different dividends and yields.  Investors should
read this section  carefully to determine  which class of shares  represents the
best investment option for their particular situation.

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.

CLASS A - PURCHASED DIRECTLY OR ACQUIRED BY EXCHANGE.

- - Offered without a sales charge.
- - Lower annual expenses than Class B shares.

CLASS B - ACQUIRED BY EXCHANGE ONLY.
- - No front-end sales charge.
- - Higher annual expenses than Class A shares.
- - A  contingent  deferred  sales charge is applied to shares sold prior to sixth
  anniversary of purchase.
- - Automatically convert to Class A shares after eight years.
- - Asset-based sales charge 0.75 of 1%. See "Class B Rule 12b-1 Plan."

CLASS C - ACQUIRED BY EXCHANGE ONLY.
- - No front-end sales charge.
- - Lower annual expenses than Class B shares.
- - A  contingent  deferred  sales  charge is applied to shares  sold prior to the
  first anniversary of purchase.

CONTINGENT DEFERRED SALES CHARGE ("CDSC")

If you acquire  shares  through an exchange  from another Lord  Abbett-sponsored
fund in which a CDSC applies and you  subsequently  redeem  them,  the Fund will
collect  and remit the CDSC to the fund in which you  originally  purchased  the
shares,  in the case of Class A and C shares.  The CDSC will be remitted to Lord
Abbett  Distributor  llc  ("Lord  Abbett  Distributor"),  in the case of Class B
shares.  The CDSC is based on the original  purchase cost or the current  market
value of the shares being sold,  whichever  is less.  There is no CDSC on shares
acquired through reinvestment of dividends.

CLASS A SHARE CDSC. 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 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 a CDSC of 1%.

CLASS B SHARE CDSC. The CDSC for Class B shares  normally  applies if you redeem
your shares before the sixth  anniversary  of their initial  purchase.  The CDSC
varies depending on how long you own your shares as shown below.

        ANNIVERSARY            CONTINGENT DEFERRED SALES
        OF THE DAY ON          CHARGE ON REDEMPTIONS
        WHICH THE PURCHASE     (AS % OF AMOUNT
        ORDER WAS ACCEPTED     SUBJECT TO CHARGE)
        ON      BEFORE
                1st            5.0%
        1st     2nd            4.0%
        2nd     3rd            3.0%
        3rd     4th            3.0%

        on or after the        None
        6th anniversary

CLASS B SHARE CDSC WAIVER. The CDSC will generally be waived under the following
circumstances: u death of the shareholder (natural person);

- - on redemptions of shares in connection with Div-Move and Systematic Withdrawal
  Plans (up to 12% per year);  
- - benefit  payments  such as Plan  loans,  hardship withdrawals,  death, 
  disability,  retirement,  separation  from  service or any
  excess  distribution under Retirement Plans; 
- - eligible mandatory  distributions under 403(b) plans and Individual Retirement
  Accounts.

See "Systematic  Withdrawal  Plan" for more information on CDSCs with respect to
Class B shares.

CLASS C SHARE  CDSC.  The 1% CDSC for  Class C shares  normally  applies  if you
redeem your shares before the first anniversary of your original purchase.

SALES COMPENSATION

Compensation payments originate from two sources: from CDSCs and from 12b-1 fees
that are paid out of the Fund's  assets.  The Fund is currently not making 12b-1
fee  payments  under the Class A and Class C share  Rule  12b-1  plans.  See the
"Investor Expenses" table for more detailed  information on CDSCs and 12b-1 fees
for Class B shares.

CLASS B RULE 12B-1 PLAN. The Fund has adopted a Class B share Rule
12b-1 Plan under which we periodically pay Lord Abbett Distributor an
annual  distribution  fee of 0.75 of 1% of the average  daily net asset value of
the Class B shares.

The 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 Class B shares at
the time of their original purchase.

proper form, the order must contain all information and  documentation  required
by the  Application  Form or  supplementally  by the Fund,  and payment  must be

SHAREHOLDER SERVICES

TELEPHONE  EXCHANGES.  You can instruct  the Fund by telephone to exchange  your
Class A shares,  purchased directly,  for Class A, B or C shares of any ELIGIBLE
FUND.  Class B and C shares may only be acquired  by exchange  for shares of the
same class of any ELIGIBLE FUND.  Certain of the tax-free,  single-state  series
may not be offered in your state.  Instructions  must be received by the Fund in
Kansas  City by  calling  800-821-5129  before  the close of the New York  Stock
Exchange ("NYSE") to exchange at the net asset value on that day.

For your protection, telephone requests for exchanges are recorded.

We will take  measures to verify the identity of the caller,  such as asking for
your name, account number, Social Security or taxpayer identification number and
other  relevant  information.   The  Fund  will  not  be  liable  for  following
instructions  communicated  by  telephone  that  it  reasonably  believes  to be
genuine. 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 limit or terminate this privilege for any  shareholder  making frequent
exchanges and may revoke the privilege for all shareholders  upon 60 days' prior
written notice. You have this privilege unless you refuse it in writing.

You  should  read the  prospectus  of the other  Lord  Abbett-sponsored  fund(s)
selected before making an exchange.

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.

DIV-MOVE.  You can invest the  dividends  paid on your account ($250 initial and
$50 subsequent minimum) into any new or existing account, within the same class,
in any  Eligible  Fund.  The  account  must be either your  account,  your joint
account with another, or a custodial account for your minor child.

SYSTEMATIC  WITHDRAWAL PLAN ("SWP"). You can make periodic cash withdrawals from
your account which are  automatically  paid to you in fixed or variable amounts.
To  participate,  the value of your shares must be at least $10,000,  except for
retirement plans for which there is no minimum.

With respect to Class B shares,  the CDSC will be waived on redemptions of up to
12% of the  current  net  asset  value of your  account  at the time of your SWP
request. For Class B share redemptions over 12% per year, the CDSC will apply to
the entire redemption.  Please contact the Fund for assistance in minimizing the
CDSC in this situation.

Redemption  proceeds  due to a SWP for  Class B (up to 12% per year) and Class C
shares, will be redeemed in the order described under "Redemptions."

RETIREMENT  PLANS.  The Lord Abbett  Family of Funds offers a range of qualified
retirement  plans,  including IRAs,  SIMPLE IRAs,  Simplified  Employee  Pension
Plans, 403(b) and pension and profit-sharing  plans,  including 401(k) plans. To
find out more about these plans, call the Fund at 800-842-0828.

SHARE CERTIFICATES. All shares are electronically recorded.  Certificated shares
are no longer available for any Class of the Fund.

ACCOUNT CHANGES. For any changes you need to make to your account,  consult your
financial representative or call the Fund at 800-821-5129.

HOUSEHOLDING.  Shareholders with the same last name and address will receive one
copy of annual or semi-annual reports, unless they request additional reports in
writing.

REDEMPTIONS

REGULAR PROCEDURE. To redeem shares you must submit a written redemption request
indicating  your share  class,  your  account  number,  the name(s) in which the
account is registered and the dollar value or number of shares you wish to sell.

Include  all  necessary  signatures  and any  additional  documents  that may be
required. If the signer has any legal capacity,  the signature and capacity must
be guaranteed by an eligible guarantor. Certain other legal documentation may be
required.  For more information  regarding proper  documentation,  telephone the
Fund.

We will verify that the shares being  redeemed were  purchased more than 15 days
earlier or were  purchased by wire and  represent an amount  sufficient to cover
the amount being redeemed.

Normally a check will be mailed to the  name(s) and address in which the account
is registered,  or otherwise according to your instruction,  within one business
day after  receipt of your  redemption  request.  The Fund reserves the right to
make payment within three business days.

EXPEDITED PROCEDURE. To be eligible for this procedure, you must have filled out
the "Expedited Telephone Redemption" section of your Application Form. To verify
whether the expedited telephone  redemption privilege is in place on an account,
or to request an  Application  Form to add it, or to change  information  for an
existing  account,  call your financial  representative or the Fund.

- - Telephone the Fund at 800-821-5129  and ask for "Expedited  Redemptions."  All
proceeds will be paid to the same bank account  designated  on your  Application
Form.  
- - Amounts of $1,000 or more normally will be wired to the designated  account on
the same day if your order is  accepted  before 12 noon  Eastern  Time or on the
next business day if accepted after such time.
- -  Amounts  of less  than  $1,000  normally  will be mailed by check on the next
business day after your order is accepted.
- - To receive the dividend for the same day you sell, your order must be accepted
after 12 noon Eastern Time.

The Fund will not be liable for following instructions communicated by telephone
that it reasonably believes to be genuine.

CHECKWRITING.  To be eligible for this  privilege,  you must have filled out the
"Checkwriting"   section  of  your  Application  Form.  To  verify  whether  the
checkwriting  privilege is in place on an account,  or to request an Application
Form to add it to an existing account, call your financial representative or the
Fund.  You can write a check for no less than $500 and no more than  $5,000,000.
SHARES 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.

This privilege should not be used to close an account because you earn dividends
until the check clears.

To determine if a CDSC applies to a redemption, the Fund redeems shares in the
following order:

1-   shares acquired by reinvestment of dividends and capital gains;
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  purchase
     (Class B) or before the first anniversary of their purchase (Class C).

NET ASSET VALUE. The net asset value of each class of shares is calculated at 12
noon and 2 p.m.  Eastern  Time  each  day  that  the  NYSE is open for  trading.
Securities are valued at cost plus (minus) amortized discount (premium), if any,
pursuant to the requirements for money market funds.

DIVIDENDS, TAXES AND YIELD

Dividends.  Our net income will be declared  as a dividend  to  shareholders  of
record as of 12 noon Eastern Time on each day the NYSE is open for trading.

Unless you elect to receive  cash,  dividends  will be  reinvested in additional
shares on the monthly  reinvestment  date.  If you elect  cash,  a check will be
mailed to you as soon as possible after the reinvestment date or, if you arrange
for direct deposit, your payment will be electronically  transferred directly to
your bank account within two days after the payable date.

If you  redeem  your  entire  account,  all  dividends  declared  to the time of
redemption will be paid to you.

TAXES.  The Fund pays no federal  income tax on the earnings it  distributes  to
shareholders.  Consequently,  dividends  you  receive  from  the  Fund,  whether
reinvested  or  taken in  cash,  are  generally  considered  taxable.  Dividends
declared in 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.

Each January you should receive, if applicable, a Form 1099 tax
information  statement  detailing your dividends and their federal tax category.
You should consult your tax adviser concerning applicable state and local taxes.

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 failed to provide a correct taxpayer identification number or to
make certain required certifications.

For  more   information   about  the  tax   consequences   from   dividends  and
distributions, see the Statement of Additional Information.

YIELD. The Fund's "yield" refers to the income generated by an investment in the
Fund over a seven-day period, which is then annualized. The "effective yield" is
calculated  similarly but, when  annualized,  the income earned is assumed to be
reinvested and will therefore be slightly  higher.  Both yield figures are based
on historical earnings and are not intended to indicate future performance.

For the seven-day period ending June 30, 1997, the Class A, B and C share yields
were 4.67%,  3.91% and 4.67%,  respectively.  For the same period, the effective
yield for Class A, B and C shares were 4.78%, 3.99% and 4.78%, respectively.  On
that day, the portfolio's dollar-weighted life to maturity was 33 days.
<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 bank  deposits  and other  investments  that pay a fixed yield for a stated
period of time or with  other  investment  companies  which may use a  different
method of computing yield.

OUR MANAGEMENT

The Fund is supervised by a board of directors,  an  independent  body which has
ultimate  responsibility for the Fund's activities.  The board has retained Lord
Abbett as investment manager pursuant to a Management Agreement. Lord Abbett has
been an  investment  manager for over 67 years and  currently  manages  over $24
billion in a family of mutual  funds and other  advisory  accounts.  Lord Abbett
provides  similar  services to twelve  other  funds  having  various  investment
objectives and also advises other investment clients. For more information about
the services Lord Abbett  provides to the Fund,  see the Statement of Additional
Information.

The Fund pays Lord  Abbett a monthly  fee based on average  daily net assets for
each month. For the fiscal year ended June 30, 1997, the fee paid to Lord Abbett
was at an annual rate of 0.50 of 1%. In addition, the Fund pays all expenses not
expressly assumed by Lord Abbett. Our Class A share ratio of expenses, including
management  fee expenses,  to average net assets for the same period was 0.84 of
1%.

THE FUND.  The Fund is a  diversified  open-end  management  investment  company
established in 1979. Its Class A, B and C shares have equal rights as to voting,
dividends,  assets and liquidation except for differences resulting from certain
class-specific expenses.

FUND PERFORMANCE

The Fund  completed  its  fiscal  year on June 30,  1997 with net assets of $144
million.

Over the past  fiscal  year,  the Fund  performed  well in a  climate  of modest
economic growth, low inflation and relatively high short-term interest rates. We
invested  entirely  in agency  discount  notes.  We also took  advantage  of the
increase in interest rates  promulgated  by the Federal  Reserve Bank by seeking
longer maturities.

Lord Abbett U.S.  Government  Securities  Money  Market  Fund,  Inc.  (sometimes
referred  to as "we" or the  "Fund")  has  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. Only Class A shares may be purchased directly and
may be acquired in exchange for shares of the same class of another Lord Abbett-
sponsored fund.  Class B and Class C shares may be acquired only in exchange for
shares of the same class of another Lord  Abbett-sponsored  fund. 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 POLICIES

FUNDAMENTAL INVESTMENT RESTRICTIONS

We are subject to the following investment  restrictions which cannot be changed
without approval of a majority of our outstanding  shares. 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

                                        2

investment adviser or any of its officers, directors, partners or employees, any
securities other than shares of the Fund's common stock.

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 the Fund 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,  the Fund  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.  An
example follows for the seven-day  period ended June 30, 1997 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
   base period                                                    $  1.000000000

Value of same account at end of base
   period                                                         $  1.000894658
Net change in account value                                       $   .000894658


                                        3

<PAGE>



Base period return (net change in
   account value divided by the
   beginning account value)                                            .0894658%

"Yield" [base period return
   times (365 divided by 7)]                                               4.67%

"Effective yield" [(base period
   return + 1) 365/7] - 1                                                  4.78%

On June 30, 1997,  our  portfolio had a  dollar-weighted  life to maturity of 33
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 the net  assets of each  fund.  A portion  of the fees
          payable by the Fund to its outside directors is being deferred under a
          plan that deems the  deferred  amounts to be invested in shares of the
          Fund for later  distribution  to the directors so that each director's
          compensation  depends  in part on the  performance  of the  Fund.  The
          amounts of the aggregate  compensation  payable by the Fund as of June
          30,  1997  deemed  invested  in  Fund  shares,   including   dividends
          reinvested  and changes in net asset value  applicable  to such deemed
          investments,  were:  Mr.  Bigelow,  $1,646;  Mr. Dixon,  $22,105;  Mr.
          Jansing, $23,557; Mr. MacDonald, $9,543; Mr. Millican, $23,924 and Mr.
          Neff,  $24,136.  If the  amounts  deemed  invested in Fund shares were
          added to each director's actual holdings of Fund shares as of June 30,
          1997, each would own, the following:  Mr. Bigelow,  1,646 shares;  Mr.
          Dixon, 22,839 shares; Mr. Jansing, 23,557 shares; Mr. McDonald, 10,640
          shares; Mr. Millican, 23,924 shares; and Mr. Neff, 26,334 shares.

     2.   The  amounts  in column 3 were  accrued  by the Lord  Abbett-sponsored
          funds for the twelve months ended October 31, 1996 with respect to the
          equity- based plans  described in footnote one and on the fees payable
          to outside  directors of the Fund for the twelve  months ended October
          31,  1996.  In  addition  to  the   equity-based   plans,   each  Lord
          Abbett-sponsored  fund  has had a  retirement  plan  for  its  outside
          directors.  The retirement plans and the equity-based plans,  however,
          were amended recently to, among other things, enable outside directors
          to elect to  convert  their  accrued  prospective  benefits  under the
          retirement  plans to amounts deemed  invested in Fund shares under the
          equity-based  plans.  Five of the six outside  directors  made such an
          election  and thus will not  receive  retainers  under the  retirement
          plan.  The recent  amendments  also  increased the annual  retainer to
          $50,000 and increased the annual retirement  benefits from 80% to 100%
          of a  director's  final annual  retainer.  Thus,  if Mr.  Jansing (the
          director  who  did  not  elect  to  convert  his  accrued  prospective
          benefits)  were to retire at or after age 72 and the  annual  retainer
          payable  by the funds were the same as it is today,  he would  receive
          annual retirement  benefits for life of $50,000.  Each retirement plan
          also  provides  for a  pre-retirement  death  benefit and  actuarially
          reduced joint-and-survivor spousal benefits.

     3.   This column shows aggregate compensation, including directors 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, 1996.

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, 1997,  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.  Ten of the  twelve  general  partners  of Lord  Abbett are
officers and/or directors of the Fund and are identified as follows:  Stephen I.
Allen, Zane E. Brown, Daniel E. Carper,  Robert S. Dow, Daria L. Foster, Paul A.
Hilstad,  Robert G. Morris,  Robert Noelke, 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, 1997,  1996 and 1995,  the  management  fees
paid to Lord Abbett amounted to $773,869, $748,926 and $775,871, respectively.

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.

                             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 may be
officers of the Fund and are 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, Martin Luther King, Jr.
Day,  President's Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,
Thanksgiving and Christmas.

We attempt to  maintain a net asset value of $1.00 per share for all classes 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 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

                                        8

<PAGE>

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. Class A shares of the Fund may be acquired either
by such an exchange or by direct purchase.

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.  Class A shares
purchased  directly from the Fund may be exchanged for Class A, B or C shares of
an  eligible  Lord  Abbett-sponsored  fund.  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 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 the appropriate 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)

                                        9

<PAGE>



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.

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,  regardless  of
whether this increase is reflected in reinvested dividends or distributions,  in
the case of Class A shares,  and due to such an increase  because of  reinvested
dividends and capital  gains,  in the case of Class B and C shares,  (ii) shares
with  respect  to which no Lord  Abbett  fund paid a 12b-1  fee 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.
                        CLASS B SHARE CONVERSION FEATURE

The conversion of Class B shares on the eighth  anniversary of their purchase is
subject to the  continuing  availability  of a private  letter  ruling  from the
Internal Revenue Service, or an opinion of counsel or tax advisor, to the effect
that the  conversion  of Class B shares does not  constitute a taxable event for
the holder under Federal income tax law. If such revenue ruling or opinion is no
longer available,  the automatic  conversion feature may be suspended,  in which
event no further conversions of Class B shares would occur while such suspension
remained in effect.  Although Class B shares could then be exchanged for Class A
shares on the basis of relative net asset value of the two classes,  without the
imposition of a sales charge or fee, such  exchange  could  constitute a taxable
event for the holder.

                                       9.
                    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.

DIV-MOVE. 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 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.

INVEST-A-MATIC.  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.

SYSTEMATIC  WITHDRAWAL PLAN. 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 the  current  net
asset value of your account at the time your SWP is established. Since the value
of shares redeemed may be more or less than their cost, gain or

                                       10

<PAGE>



loss may be recognized for income tax purposes on each periodic payment. The SWP
may be terminated by you or by us at any time by written notice.

RETIREMENT  PLANS.  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 and Simple IRA's),
403(b) plans and qualified pension and  profit-sharing  plans,  including 401(k)
plans. The forms 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.

REDEMPTIONS.  A  redemption  order is in proper form when it contains all of the
information and  documentation  required by the order form or  supplementally by
Lord Abbett Distributor or the Fund to carry out the order. The signature(s) and
any legal capacity of the signer(s) must be guaranteed by an eligible guarantor.
See the Prospectus for expedited redemption procedures.

The right to redeem and receive payment, as described in the Prospectus,  may be
suspended if the NYSE is closed  (except for  weekends or  customary  holidays),
trading on the NYSE is  restricted  or the  Securities  and Exchange  Commission
deems an emergency to exist.

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.

                        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
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.

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.

                                       12

<PAGE>


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.

                                      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.

The  foregoing  discussion  relates  solely to U.S.  federal  income  tax law as
applicable to United States  persons  (United  States  citizens or residents and
United Sates  domestic  corporations,  partnerships,  trusts and estates).  Each
shareholder  who is not a United States  person  should  consult his tax adviser
regarding  the U.S. and foreign tax  consequences  of the ownership of shares of
the Fund,  including a 30% (or lower treaty rate) United States  withholding tax
on dividends  representing ordinary income and net short-term capital gains, and
the  applicability  of United States gift and estate taxes to non-United  States
persons who own Fund shares.

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.

                                       13.

Item 25.    Persons Controlled by or Under Common Control with Registrant

                   None.

Item 26.    Number of Record Holders of Securities

            At October 24, 1997 - Class A - 10,968
                                  Class B - 28
                                  Class C - 77
 

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
<PAGE>

     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  conditions  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  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.
                 (formerly LORD ABBETT CASH RESERVE FUND, INC.)

                              MANAGEMENT AGREEMENT


                  AGREEMENT  made as of this  14th day of  October,  1981 by and
between  LORD ABBETT U.S.  GOVERNMENT  SECURITIES  MONEY  MARKET  FUND,  INC., a
Maryland Corporation (hereinafter called the "Corporation"),  and LORD, ABBETT &
CO., a New York partnership (hereinafter called the "Investment Manager").

                  WHEREAS,  the  Corporation,  desires to obtain the  investment
management  services of the  Investment  Manager and the  Investment  Manager is
willing to provide  services of the nature desired upon the terms and conditions
hereinafter provided.

                  NOW,  THEREFORE,  in consideration of the mutual covenants and
of  other  good  and  valuable   consideration,   receipt  of  which  is  hereby
acknowledged, it is agreed as follows:

                  1. The Corporation hereby employs the Investment Manager under
the terms and conditions of this  Agreement,  and the Investment  Manager hereby
accepts  such  employment  and agrees to perform  supervisory  functions  of the
Corporation  with respect to the investment and reinvestment of its property and
assets  (whether  or not  held in  trust  or in the  custody  of a bank or trust
company subject to the Corporation's  direction or control)  including,  without
limitation,  the supervision of its investment  portfolio and the recommendation
of investment policies and procedures within the

<PAGE>

limitations set forth in the Corporation's  Registration  Statement on file with
the Securities and Exchange  Commission under the Securities Act of 1933 and the
Investment Company Act of 1940, as amended (the "Act").

                  The   Investment   Manager  agrees  to  maintain  an  adequate
organization of competent persons to perform the supervisory functions mentioned
herein.

                  All recommendations with respect to the investment  portfolios
will be made to the Corporation's trading department which, with the approval of
authorized  officers of the  Corporation,  will execute all trades in accordance
with the Corporation's investment procedures.

                  The Investment  Manager reserves the right, in its discretion,
to purchase or otherwise obtain statistical  information and services from other
sources, including affiliated persons of the Investment Manager.

                  Notwithstanding  the  provisions  of  this  paragraph  1,  the
investment policies and procedures and all other actions of the Corporation are,
and shall at all times be,  subject to the control and direction of its Board of
Directors.

                  2. The  Corporation  agrees to pay the Investment  Manager for
its services under this Agreement and for the expenses assumed, a management fee
computed and payable  monthly at the annual rate of three  quarters .50 of 1% of
the  value of the  Corporation's  average  daily  net  assets  not in  excess of
$250,000,000, .45 of 1%


<PAGE>



of such  assets not in excess of  $500,000,000  and .40 of 1% of such  assets in
excess of  $500,000,000.  The value of the net assets of the  Corporation  shall
include  all assets  held in trust or in custody  of any bank,  savings  bank or
trust  company for the  Corporation,  subject to its control or  direction,  and
shall  be  determined  as  provided  in the  Articles  of  Incorporation  of the
Corporation.  The fee  shall  be paid on the  first  day of each  month  for the
preceding month.

         It is understood that any supplemental advisory or statistical services
which may be provided to the Corporation or to the Investment  Manager from time
to time by  independent  broker-dealers  or persons  other  than the  Investment
Manager, for whatever reason, shall not reduce the amount of the fees payable to
the  Investment  Manager  hereunder.  It is recognized  that such  supplementary
advisory or statistical services may be useful to the Investment Manager and the
Corporation,  but their value is  indeterminable  and is not to be  considered a
substitute for the services provided by the Investment Manager hereunder.

                  3.  It is  understood  that  the  services  of the  Investment
Manager  are not deemed to be  exclusive,  and nothing in this  Agreement  shall
prevent the Investment  Manager, or any officer,  director,  partner or employee
thereof, from providing similar services to other investment companies and other
clients (whether or not their investment objectives and policies are similar to

                                        3

those of the Corporation) or to engage in other  activities.  When other clients
of the Investment Manager desire to purchase or sell the same portfolio security
at the same time as the  Corporation,  it is understood  that such purchases and
sales will be made as nearly as practicable on a pro rata basis in proportion to
the amounts desired to be purchased or sold by each client.

                  4. The  Corporation  will, at its own expense,  furnish to the
Investment Manager periodic (but not less than semi-annually)  statements of its
books of account,  including  balance  sheets and earnings  statements,  and all
other  information  which may reasonably be required,  from time to time, by the
Investment  Manager,  and  will,  at its own  expense,  at all  times  keep  the
Investment  Manager fully advised as to the cash,  securities and other property
then comprising its assets,  and furnish daily detailed price makeup sheets with
respect to its investment portfolio and shares of its capital stock.

                  5. The Investment  Manager shall be under no obligation to pay
any fees,  costs,  expenses or other charges of the Corporation,  except for the
compensation  of  its  officers  and  directors  who  are  affiliated  with  the
Investment Manager, sales and promotional costs, including the costs of printing
prospectuses used for offering shares other than to existing shareholders,  rent
for its office  space;  and except for the  ordinary  and  necessary  office and
clerical expenses relating to research, statistical work

                                        4

and supervision of the Corporation's  investment  portfolio,  to be performed by
the Investment Manager under paragraph 1 of this Agreement. The Corporation will
pay all other  fees,  cost,  expenses  or  charges  relating  to its  assets and
operations,  including  without  limitation,  office and  clerical  expenses not
relating to research,  statistical  work and  supervision  of the  Corporation's
investment  portfolio;  fees and expenses of directors not  affiliated  with the
investment  Manager,  governmental fees;  interest charges,  taxes,  association
membership  dues;  fees and charges for legal and auditing  services  (including
preparation  of tax  returns);  fees and expenses of any  custodians or trustees
with  respect to custody of its assets;  fees,  charges and expenses of dividend
disbursing agents, registrars and transfer agents (including the cost of keeping
all  necessary  shareholder  records and  accounts,  and  handling  any problems
relating thereto,  and the expense of furnishing to all shareholders  statements
of their  accounts after every  transaction,  including the expense of mailing);
cost  and  expense  of  preparing,  printing  and  mailing  stock  certificates,
prospectuses and reports,  notices and proxy statements to shareholders and cost
of preparing reports to governmental agencies; brokerage fees and commissions of
every kind and expenses in connection  with the execution of portfolio  security
transactions (including the cost of any service or agency designed to facilitate
the purchase and sale of portfolio securities); insurance premiums;

                                        5

<PAGE>



the cost of qualification  and  registration,  of the Corporation and its shares
under federal, state and other securities laws; and any other fee, cost, expense
or charge of any kind not expressly assumed by the Investment Manager under this
Agreement.

                  Notwithstanding  the above,  the  Investment  Manager will pay
expenses of the  Corporation  in excess of 1/2 of 1% of average daily net assets
for the first 120 days following the effective date of the initial  Registration
Statement of the Corporation  filed with the Securities and Exchange  Commission
under the Securities Act of 1933; thereafter, the Investment Manager may, but is
not  required  to, pay all or any  portion of expenses  of the  Corporation  not
expressly  assumed  by the  Investment  Manager  under the  Agreement.  Any such
expenses  paid by the  Investment  Manager  which  are not  reimbursable  by the
Investment Manager pursuant to state expense  limitations  described below shall
be paid back to the Investment Manager by the Corporation.  Such repayment shall
be made as  follows:  for any month that the  Corporation's  ratio of  operating
expenses  to average net asses on an  annualized  basis is less than 8/10 of 1%,
the  Corporation  shall pay the Investment  Manger an amount equal in dollars to
the  difference in dollars  between the expenses at the actual expense ratio and
those at a ratio of 8/10 of 1%;  any such  payments  shall be made  monthly  and
shall  continue  until  the  amount  of  reimbursement  is paid in full or until
September 30, 1988, whichever first occurs.

                                        6

<PAGE>



                  Notwithstanding  any other  provision  of this  Agreement,  if
expenses (including the management fee hereunder but excluding interest,  taxes,
brokerage  fees,  and  where  permitted,  extraordinary  expenses)  borne by the
Corporation  in any fiscal year exceed  expense  limitations  applicable  to the
Corporation imposed by state securities administrators,  as such limitations may
be lowered or raised from time to time, the Investment Manger will reimburse the
Corporation for any such excess.

  If the  Investment  Manager  pays for other  expenses  of the  Corporation  or
furnishes without charge to the Corporation  services the cost of which is to be
borne by the Corporation under this Agreement,  the Investment Manager shall not
be deemed to have waived its rights under this Agreement to have the Corporation
pay for such expenses or provide or pay for such services in the future.

                  6. The Investment  Manager agrees that it shall observe and be
bound by all of the provisions of the Articles of  Incorporation  (including any
amendments  thereto) of the Corporation which shall in any way limit or restrict
or prohibit or otherwise regulate any action by the Investment Manager.

                  7. The Investment Manager assumes no responsibility under this
Agreement and, having so acted, the Investment  Manager shall not be held liable
or accountable  for any mistakes of law or fact, or for any error or omission of
its officers, directors,

                                        7

<PAGE>



partners or employees,  or for any loss or damage arising or resulting therefrom
suffered by the Corporation or any of its stockholders,  creditors, directors or
officers;  provided however,  that nothing herein shall be deemed to protect the
Investment   Manager  against  any  liability  to  the  Corporation  or  to  its
stockholders by reason of willful misfeasance,  bad faith or gross negligence in
the performance of its duties hereunder,  or by reason of the reckless disregard
of its obligations  and duties  hereunder.  The Investment  Manager shall not be
responsible  for any  action of the Board of  Directors  of the  Corporation  in
following or declining to follow any advice or  recommendation of the Investment
Manager.

                  8. Neither this  Agreement nor any other  transaction  between
the parties hereto pursuant to this Agreement shall be invalidated or in any way
affected by the fact that any or all of the directors,  officers,  stockholders,
or other  representatives  of the  Corporation  are or may be  interested in the
Investment  Manager, or any successor or assignee thereof, or that any or all of
the directors,  officers,  partners,  or other representatives of the Investment
Manager are or may be interested in the Corporation,  except as otherwise may be
provided in the Investment Company Act of 1940. The Investment Manager in acting
hereunder  shall  be  an  independent  contractor  and  not  any  agent  of  the
Corporation.

                  9. This  Agreement  shall become  effective upon the effective
date of the Registration Statement of the Corporation

                                        8

filed with the  Securities and Exchange  Commission  under the Securities Act of
1933 on May 21,  1979,  and  continue  in force until  February 4, 1981,  and is
renewable annually  thereafter by specific approval of the Board of Directors of
the Corporation or by vote of a majority of the outstanding voting securities of
the Corporation; any such renewal shall be approved by the vote of a majority of
the directors who are not parties to this Agreement or interested persons of the
Investment Manager or of the Corporation,  cast in person or at a meeting called
for the purpose of voting on such approval.

                  This Agreement may be terminated  without  penalty at any time
by  the  Corporation  upon  60  days'  written  notice.   This  Agreement  shall
automatically  terminate in the event of its assignment.  The terms  "interested
persons",  "assignment"  and  "vote  of a  majority  of the  outstanding  voting
securities"  shall  have the same  meaning  as those  terms are  defined  in the
Investment Company Act of 1940.

                  10. The Investment Manager reserves the right to grant the use
of the name "LORD ABBETT" or "LORD, ABBETT & CO.", or any derivative thereof, to
any other  investment  company or business  enterprise.  The Investment  Manager
reserves the right to withdraw  from the  Corporation  the use of the name "LORD
ABBETT" and the use of its  registered  service mark; at such time of withdrawal
of the right to use the name "LORD ABBETT", the Investment Manager agrees

                                        9

<PAGE>


that the question of continuing this Agreement may be submitted to a vote of the
Corporation's  shareholders.  In the event of such withdrawal or the termination
of this Agreement,  for any reason, the Corporation will, on the written request
of the  Investment  Manager,  take such action as may be necessary to change its
name and eliminate  all  reference to the words "LORD  ABBETT" in any form,  and
will no longer use such registered service mark.

         IN WITNESS  WHEREOF,  the  Corporation  has caused this Agreement to be
executed by its duly  authorized  officers and its corporate  seal to be affixed
hereto,  and the Investment  Manager has caused this Agreement to be executed by
one of its partners all on the day and year first above written.

DELOITTE & TOUCHE LLP

New York, New York

                   Rule 12b-1 Distribution Plan and Agreement
            Lord Abbett Developing Growth Fund, Inc. -- Pension Class


     RULE 12b-1  DISTRIBUTION PLAN AND AGREEMENT dated as of October __, 1997 by
and between LORD ABBETT  DEVELOPING  GROWTH FUND, INC., a Maryland  Corporation,
(the  "Fund"),  on behalf of its Pension  Class (the  "Class"),  and LORD ABBETT
DISTRIBUTOR LLC, a New York limited liability company (the "Distributor").

         WHEREAS,  the  Fund  is  an  open-end  management   investment  company
registered under the Investment Company Act of 1940, as amended (the "Act"); and
the  Distributor  is the  exclusive  selling  agent  of  the  Fund's  shares  of
beneficial interest, including the Class, pursuant to the Distribution Agreement
between the Fund and the Distributor, dated July 12, 1996, and

         WHEREAS,  the Fund desires to adopt a  Distribution  Plan and Agreement
(the  "Plan") for the Class with the  Distributor,  as  permitted  by Rule 12b-1
under the Act,  pursuant  to which the Class may make  certain  payments  to the
Distributor for payment to institutions and persons  permitted by applicable law
and/or rules to receive such payments ("Authorized  Institutions") in connection
with sales of Shares and for use by the  Distributor  as provided in paragraph 3
of this Plan, and

         WHEREAS,  the Fund's Board of Directors has determined  that there is a
reasonable  likelihood  that the Plan will  benefit the Class and the holders of
the Shares.

         NOW,  THEREFORE,  in consideration of the mutual covenants and of other
good and valuable consideration,  receipt of which is hereby acknowledged, it is
agreed as follows:

         1. The Fund hereby  authorizes the Distributor to enter into agreements
with  Authorized  Institutions  (the  "Agreements")  which may  provide  for the
payment to such Authorized  Institutions of distribution  and service fees which
the Distributor  receives from the Class in order to provide  incentives to such
Authorized  Institutions  (i) to sell  Shares  and  (ii) to  provide  continuing
information  and  investment  services  to their  accounts  holding  Shares  and
otherwise  to encourage  their  accounts to remain  invested in the Shares.  The
Distributor  may, from time to time, waive or defer payment of some fees payable
at the time of the sale of Shares provided for under paragraph 2 hereof.

         2. Subject to possible reduction as provided below in this paragraph 2,
the  Class  shall  pay to the  Distributor  fees  at  each  quarter-end  (a) for
services,  at an annual rate not to exceed .25 of 1% of the  average  annual net
asset  value  of  Shares  outstanding  for  the  quarter  or  more  and  (b) for
distribution,  at an annual rate not to exceed .50 of 1% of the  average  annual
net asset value of Shares  outstanding  for the quarter or more. For purposes of
the quarter-end  fee payments  above,  (A) Shares issued pursuant to an exchange
for shares of another series of the Fund or another Lord  Abbett-sponsored  fund
(or for shares of a fund  acquired by the Fund) will be  credited  with the time
held from the initial  purchase of such other shares when  determining  how long
Shares  mentioned in clauses (a) and (b) have been  outstanding and (B) payments
will be based on Shares outstanding during any such quarter.  Shares outstanding
in clause (a) and (b) above include Shares issued for


<PAGE>



reinvested  dividends  and  distributions  which have been  outstanding  for the
quarter or more.

         The Board of  Directors  of the Fund shall from time to time  determine
the amounts and the time of payments (such as, at the time of sale, quarterly or
otherwise),  within the foregoing  maximum  amounts,  that the Class may pay the
Distributor  hereunder.  Such  determinations by the Board of Directors shall be
made by votes of the kind referred to in paragraph 10 of this Plan.  The service
fees mentioned in this  paragraph are for the purposes  mentioned in clause (ii)
of  paragraph  1 of  this  Plan  and the  distribution  fees  mentioned  in this
paragraph  are for the  purposes  mentioned in clause (i) of paragraph 1 and the
second  sentence of paragraph 3 of this Plan. The  Distributor  will monitor the
payments  hereunder  and shall reduce such  payments or take such other steps as
may be necessary to assure that (x) the payments  pursuant to this Plan shall be
consistent with Rule 2830, subparagraphs (d)(2) and (5) of the Conducts Rules of
the National Association of Securities Dealers,  Inc. with respect to investment
companies with asset-based  sales charges and service fees as the same may be in
effect  from time to time and (y) the Class  shall not pay with  respect  to any
Authorized  Institution service fees equal to more than .25 of 1% of the average
annual net asset  value of Shares  sold by (or  attributable  to shares sold by)
such Authorized Institution and held in an account covered by an Agreement.

         3.  Within the  foregoing  maximum  amounts,  the  Distributor  may use
amounts  received as  distribution  fees hereunder from the Class to finance any
activity which is primarily  intended to result in the sale of Shares including,
but not  limited  to,  commissions  or other  payments  relating  to  selling or
servicing  efforts.  Without  limiting  the  generality  of the  foregoing,  the
Distributor  may apply  amounts  authorized  by the  Fund's  Board of  Directors
designated as the  distribution  fee referred to in clause (b) of paragraph 2 to
expenses incurred by the Distributor if such expenses are primarily  intended to
result in the sale of  Shares.  The  Fund's  Board of  Directors  (in the manner
contemplated in paragraph 10 of this Plan) shall approve the timing,  categories
and calculation of any payments under this paragraph 3 other than those referred
to in the foregoing sentence.

         4. The net asset value of the Shares shall be determined as provided in
the Articles of  Incorporation  of the Fund. If the Distributor  waives all or a
portion of fees  which are to be paid by the Class  hereunder,  the  Distributor
shall not be deemed to have waived its rights  under this  Agreement to have the
Class pay such fees in the future.

         5. The  Secretary  of the Fund,  or in his absence the Chief  Financial
Officer,  is hereby  authorized  to direct  the  disposition  of monies  paid or
payable  by the  Class  hereunder  and  shall  provide  to the  Fund's  Board of
Directors,  and the Board of  Directors  shall  review,  at least  quarterly,  a
written report of the amounts so expended pursuant to this Plan and the purposes
for which such expenditures were made.

         6.  Neither  this Plan nor any other  transaction  between  the parties
hereto  pursuant to this Plan shall be invalidated or in any way affected by the
fact  that  any or  all  of the  directors,  officers,  shareholders,  or  other
representatives  of  the  Fund  are  or  may  be  "interested  persons"  of  the
Distributor,  or any  successor or assignee  thereof,  or that any or all of the
directors,   officers,   partners,  members  or  other  representatives  of  the
Distributor are or may be "interested  persons" of the Fund, except as otherwise
may be provided in the Act.



<PAGE>



         7. The Distributor shall give the Fund the benefit of the Distributor's
best  judgment  and good faith  efforts in rendering  services  under this Plan.
Other than to abide by the provisions  hereof and render the services called for
hereunder in good faith, the Distributor  assumes no  responsibility  under this
Plan and,  having so acted,  the  Distributor  shall not be held  liable or held
accountable for any mistake of law or fact, or for any loss or damage arising or
resulting  therefrom suffered by the Fund, the Class or any of the shareholders,
creditors,  directors or officers of the Fund;  provided  however,  that nothing
herein shall be deemed to protect the  Distributor  against any liability to the
Fund or the Class' shareholders by reason of willful  misfeasance,  bad faith or
gross negligence in the performance of its duties hereunder, or by reason of the
reckless disregard of its obligations and duties hereunder.

         8. This Plan  shall  become  effective  on the date  hereof,  and shall
continue  in  effect  for a period  of more than one year from such date only so
long as such continuance is specifically approved at least annually by a vote of
the Board of  Directors  of the Fund,  including  the vote of a majority  of the
directors who are not "interested persons" of the Fund and who have no direct or
indirect  financial  interest in the  operation of this Plan or in any agreement
related to this  Plan,  cast in person at a meeting  called  for the  purpose of
voting on such renewal.

         9. This Plan may not be amended to increase materially the amount to be
spent by the Class  hereunder  without the vote of a majority of its outstanding
voting securities and each material  amendment must be approved by a vote of the
Board  of  Directors  of the  Fund,  including  the  vote of a  majority  of the
directors who are not "interested persons" of the Fund and who have no direct or
indirect  financial  interest in the  operation of this Plan or in any agreement
related to this  Plan,  cast in person at a meeting  called  for the  purpose of
voting on such amendment.

         10. Amendments to this Plan other than material  amendments of the kind
referred to in the  foregoing  paragraph 9 of this Plan may be adopted by a vote
of the Board of Directors of the Fund,  including  the vote of a majority of the
directors who are not "interested persons" of the Fund and who have no direct or
indirect  financial  interest in the  operation of this Plan or in any agreement
related to this Plan.  The Board of  Directors  of the Fund may, by such a vote,
interpret this Plan and make all  determinations  necessary or advisable for its
administration.

         11. This Plan may be  terminated at any time without the payment of any
penalty by (a) the vote of a majority of the  directors  of the Fund who are not
"interested  persons"  of the Fund  and have no  direct  or  indirect  financial
interest in the operation of this Plan or in any agreement related to this Plan,
or (b) by a shareholder  vote in compliance with Rule 12b-1 and Rule 18f-3 under
the Act as in effect at such time.

         12. So long as this Plan shall  remain in  effect,  the  selection  and
nomination of those  directors of the Fund who are not  "interested  persons" of
the Fund are committed to the discretion of such  disinterested  directors.  The
terms  "interested  persons,"  "assignment"  and  "vote  of a  majority  of  the
outstanding  voting  securities"  shall have the same meaning as those terms are
defined in the Act.

         IN WITNESS  WHEREOF,  each of the parties has caused this instrument to
be executed in its name and on its behalf by its duly authorized  representative
as of the date first above written.

                                            By:
                                                A Partner



                                                                      Exhibit 16





                                Yield Calculation

We calculate  our "yield" and  "effective  yield" based on the number of days in
the period for which the  calculation  is made ("base  period").  Our "yield" is
computed by determining the net change for the base period (exclusive of capital
charges) in the value of a hypothetical  preexisting account having a balance of
one share at the start of the base  period by  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.  An example  follows for the
seven-day  period  ended June 30, 1997 of the  calculation  of both  "yield" and
"effective yield":

Value of hypothetical account with
   exactly one share at beginning of
   base period                                                      $1.000000000
________________________________________________________________________________

Value of same account at end of base
 period                                                             $1.000894658
   Net change in account value                                      $ .000894658

                                                                                

Base period return (net change in
   account value divided by the
   beginning account value)                                            .0894658%

"Yield" [base period return
   times (365 divided by 7)]                                               4.67%

On June 30, 1997,  our  portfolio had a  dollar-weighted  life to maturity of 33
days.

                          (As adopted August 15, 1996)


         Rule 18f-3 (the "Rule")  under the  Investment  Company Act of 1940, as
amended (the "1940 Act"), requires that the Board of Directors or Trustees of an
investment company desiring to offer multiple classes pursuant to the Rule adopt
a plan setting  forth the separate  arrangement  and expense  allocation of each
class, and any related conversion features or exchange privileges. This document
constitutes   an  amended  and  restated  plan   (individually,   a  "Plan"  and
collectively,  the  "Plans")  of each of the  investment  companies,  or  series
thereof,  listed on Schedule A attached hereto (each, a "Fund"). The Plan of any
Fund is subject to  amendment  by action of the Board of  Directors  or Trustees
(the  "Board")  of such Fund and without the  approval  of  shareholders  of any
class,  to the extent  permitted by law and by the  governing  documents of such
Fund.

         The Board,  including a majority of the  non-interested  Board members,
has determined that the following separate  arrangement and expense  allocation,
and the related conversion features,  if any, and exchange  privileges,  of each
class  of each  Fund  are in the  best  interest  of  each  class  of each  Fund
individually and each Fund as a whole.

1. CLASS  DESIGNATION.  Shares of all Funds except Lord Abbett Series Fund, Inc.
shall be  divided  into  Class A shares,  Class B shares,  Class C,  Class Y and
Pension Class shares as indicated  for each Fund on Schedule A attached  hereto.
In the case of the Lord Abbett Series Fund - Growth & Income  Portfolio,  shares
shall be divided into Variable Contract Class shares and Pension Class shares as
indicated on Schedule A.

2.       SALES CHARGES AND DISTRIBUTION AND SERVICE FEES.

         (a) INITIAL SALES CHARGE. Class A shares will be traditional  front-end
sales  charge  shares,  offered at their net asset  value  ("NAV")  plus a sales
charge in the case of each Fund as described in such Fund's  prospectus  as from
time to time in effect.

         Class B shares, Class C shares, Class Y shares, Variable Contract Class
shares and Pension  Class shares will be offered at their NAV without an initial
sales charge.

         (b) SERVICE AND  DISTRIBUTION  FEES.  In respect of the Class A shares,
Class B shares, Class C shares, Variable Contract Class shares and Pension Class
shares,  each Fund will pay service  and/or  distribution  fees under plans from
time to time in effect adopted for such classes pursuant to Rule 12b-1 under the
1940 Act (each, a "12b-1 Plan").

         Pursuant  to a 12b-1  Plan  with  respect  to the  Class A  shares,  if
effective,  each Fund will generally pay (i) at the time such shares are sold, a
one-time  distribution  fee of up to 1% of the  NAV of the  shares  sold  in the
amount of $1 million or more, including sales qualifying at such level under the
rights of accumulation and statement of intention  privileges,  or to retirement
plans with 100 or more eligible employees, as described in the Fund's prospectus
as from time to time in effect, (ii) a


<PAGE>



continuing  distribution fee at an annual rate of 0.10% of the average daily NAV
of the Class A share  accounts of dealers who meet certain sales and  redemption
criteria,  and (iii) a  continuing  service  fee at an annual rate not to exceed
0.25% of the  average  daily NAV of the Class A shares.  The Board will have the
authority to increase the  distribution  fees payable under such 12b-1 Plan by a
vote of the Board, including a majority of the independent directors thereof, up
to an annual rate of 0.25% of the average  daily NAV of the Class A shares.  The
effective  dates of various of the 12b-1  Plans for the Class A shares are based
on achievement by the Funds of specified total net assets for the Class A shares
of such Funds.

         Pursuant  to a 12b-1  Plan  with  respect  to the  Class B  shares,  if
effective,  each Fund will generally pay a continuing  annual fee of up to 1% of
the average annual NAV of such shares then outstanding (each fee comprising .25%
in service fee and .75% in distribution fee).

         Pursuant  to a 12b-1  Plan  with  respect  to the  Class C  shares,  if
effective,  each Fund will generally pay a one-time service and distribution fee
at the time  such  shares  are sold of up to 1% of  their  NAV and a  continuing
annual fee, commencing 12 months after the first anniversary of such sale, of up
to 1% of the  average  annual  NAV of such  shares  then  outstanding  (each fee
comprising .25% in service fees and .75% in distribution fees).

         Pursuant to a 12b-1 plan with respect to the Variable  Contract  Class,
if  operational,  the Growth & Income  Portfolio will generally pay a continuing
annual  fee of up to  .15%  of  the  average  annual  NAV of  such  shares  then
outstanding to reimburse an insurance company for its expenditure related to the
distribution  of  such  shares  which  expenditures  are not  also  reimbursable
pursuant  to fees paid  under the  variable  contract  issued by such  insurance
company.

         Pursuant  to a  12b-1  Plan  with  respect  to the  Pension  Class,  if
operational,  the Growth & Income  Portfolio  will  generally  pay a  continuing
annual fee of .45% of the average  annual NAV of such  shares then  outstanding.
The Board will have the  authority  to increase  the  distribution  fees payable
under  such  12b-1 Plan by a vote of the  Board,  including  a  majority  of the
independent  directors  thereof,  up to an annual  rate of 0.75% of the  average
daily NAV of such  shares  (consisting  of  distribution  and service  fees,  at
maximum annual rates not exceeding 0.50 and 0.25 of 1%, respectively).

         The Class Y shares do not have a Rule 12b-1 Plan.

         (c)  CONTINGENT  DEFERRED  SALES  CHARGES  ("CDSC").  Subject  to  some
exceptions,  Class A shares subject to the one-time sales distribution fee of up
to 1% under the Rule 12b-1 Plan for the Class A shares will be subject to a CDSC
equal to 1% of the lower of the cost or the NAV of such shares if the shares are
redeemed  for cash on or before  the end of the  twenty-fourth  month  after the
month in which the shares were purchased.

         Class B shares will be subject to a CDSC  ranging  from 5% to 1% of the
lower of the cost or the NAV of the shares,  if the shares are redeemed for cash
before the sixth anniversary of their purchase.  The CDSC for the Class B shares
may be waived for certain transactions. Class C shares will be subject to a CDSC
equal to 1% of the lower of the cost or the NAV of the  shares if the shares are
redeemed for cash before the first anniversary of their purchase.


<PAGE>



         Neither the Class Y,  Variable  Contract  Class nor the  Pension  Class
shares will be subject to a CDSC.

 3. CLASS-SPECIFIC  EXPENSES. The following expenses shall be allocated,  to the
extent such  expenses can  reasonably  be identified as relating to a particular
class and consistent with Revenue  Procedure 96-47, on a  class-specific  basis:
(a) fees under a 12b-1 Plan applicable to a specific class (net of any CDSC paid
with  respect  to shares of such class and  retained  by the Fund) and any other
costs  relating to  implementing  or  amending  such Plan,  including  obtaining
shareholder  approval of such Plan or any  amendment  thereto;  (b) transfer and
shareholder servicing agent fees and shareholder servicing costs identifiable as
being  attributable  to the  particular  provisions  of a  specific  class;  (c)
stationery,  printing,  postage and delivery  expenses  related to preparing and
distributing  materials  such as  shareholder  reports,  prospectuses  and proxy
statements to current  share holders of a specific  class;  (d)  Securities  and
Exchange  Commission  registration  fees incurred by a specific class; (e) Board
fees or expenses  identifiable as being  attributable  to a specific class;  (f)
fees for outside  accountants and related expenses relating solely to a specific
class;  (g) litigation  expenses and legal fees and expense relating solely to a
specific class; (h) expenses incurred in connection with  shareholders  meetings
as a result of issues relating solely to a specific class and (i) other expenses
relating  solely to a specific  class,  provided,  that  advisory fees and other
expenses related to the management of a Fund's assets (including  custodial fees
and tax-return  preparation  fees) shall be allocated to all shares of such Fund
on the basis of NAV,  regardless of whether they can be specifically  attributed
to a particular  class. All common expenses shall be allocated to shares of each
class at the same time they are  allocated  to the shares of all other  classes.
All such expenses  incurred by a class of shares will be charged directly to the
net assets of the particular class and thus will be borne on a pro rata basis by
the  outstanding  shares of such class.  For all Funds,  with the  exception  of
Series Fund - Growth & Income  Portfolio,  Blue Sky expenses  will be treated as
common expenses.  In the case of Series Fund - Growth & Income  Portfolio,  Blue
Sky expenses will be allocated  entirely to the Pension  Class,  as the Variable
Contract  Class  of  Series  Fund  Growth  &  Income  Portfolio  has no Blue Sky
expenses.

4. INCOME AND EXPENSE ALLOCATIONS. Income, realized and unrealized capital gains
and losses and  expenses  not  allocated  to a class as provided  above shall be
allocated to each class on the basis of the net assets of that class in relation
to the net assets of the Fund,  except that, in the case of each daily  dividend
Fund, income and expenses shall be allocated on the basis of relative net assets
(settled shares).

5. DIVIDENDS AND  DISTRIBUTIONS.  Dividends and Distributions  paid by a Fund on
each class of its shares,  to the extent paid,  will be  calculated  in the same
manner,  will be paid at the same time,  and will be in the same amount,  except
that the amount of the dividends  declared and paid by a particular class may be
different from that paid by another class because of expenses borne  exclusively
by that class.

6.  NET  ASSET  VALUES.  The NAV of each  share  of a class  of a Fund  shall be
determined in accordance  with the Articles of  Incorporation  or Declaration of
Trust of such Fund with  appropriate  adjustments to reflect the  allocations of
expenses,  income and realized and  unrealized  capital gains and losses of such
Fund between or among its classes as provided above.

7. CONVERSION FEATURES. The Class B shares will automatically convert to Class A
shares 8 years after the date of  purchase.  Such  conversion  will occur at the
relative NAV per share of each Class without the imposition of any sales charge,
fee or other charge. When Class B shares convert,  any other Class B shares that
were  acquired  by  the  shareholder  by  the   reinvestment  of  dividends  and
distributions  will  also  convert  to Class A shares on a pro rata  basis.  The
conversion  of Class B shares to Class A shares  after 8 years is subject to the
continuing  availability  of a private  letter ruling from the Internal  Revenue
Service or an opinion of  counsel  to the effect  that the  conversion  does not
constitute a taxable event for the Class B shareholder  under Federal income tax
law. If such a revenue ruling or opinion is no longer  available,  the automatic
conversion  feature may be suspended,  in which event no further  conversions of
Class B shares would occur while such suspension remained in effect.

         Subject to  amendment  by the Board,  Class A shares and Class C shares
shall not be subject to any automatic conversion feature.

8. EXCHANGE PRIVILEGES.  Except as set forth in a Fund's prospectus as from time
to time in  effect,  shares of any class of such Fund may be  exchanged,  at the
holder's  option,  for shares of the same class of another  Fund,  or other Lord
Abbett-sponsored  fund or series  thereof,  without the  imposition of any sales
charge, fee or other charge.

         Each Plan is  qualified by and subject to the terms of the then current
prospectus for the applicable Fund;  provided,  however,  that none of the terms
set forth in any such prospectus shall be inconsistent  with the terms contained
herein. The prospectus for each Fund contains additional  information about that
Fund's classes and its multiple-class structure.

         Each Plan is being  adopted  for a Fund with the  approval  of, and all
material amendments thereto must be approved by, a majority of the Board of such
Fund,  including a majority of the Board who are not  interested  persons of the
Fund.
