                                                Strategic Core Fixed Income Fund

GOAL

     The  investment  objective  of  each  Fund is to seek  income  and  capital
     appreciation to produce a high total return.

PRINCIPAL STRATEGY

     The  Core  Fixed  Income  Fund  invests   primarily  in  U.S.   Government,
     mortgage-backed  and  investment  grade debt  securities,  including  those
     issued by non-U.S.  entities  but  denominated  in U.S.  dollars  (known as
     "Yankees"). The Strategic Core Fixed Income Fund invests primarily in those
     securities,  as well as in high yield  debt  securities  (sometimes  called
     "lower-rated  bonds" or "junk  bonds")  and  securities  issued by non-U.S.
     entities  and  denominated  in  currencies  other  than  the  U.S.  dollar.
     Investments  in high yield debt and non-U.S.  debt  denominated  in foreign
     currencies  are each  limited to 20% of the  Strategic  Core  Fixed  Income
     Fund's net assets.

     Both Funds attempt to manage, but not eliminate, interest rate risk through
     their  management  of the  average  duration of the  securities  they hold.
     Duration is a mathematical  concept that measures a portfolio's exposure to
     interest  rate changes.  The Funds expect to maintain its average  duration
     range  within two years of the bond  market's  duration  as measured by the
     Lehman Aggregate Bond Index (currently approximately 5 years). The higher a
     Fund's duration, the more sensitive it is to interest rate risk.

     Each Fund may  engage in  active  and  frequent  trading  of its  portfolio
     securities  to  achieve  its  principal  investment  strategies  and can be
     expected to have portfolio turnover rates  substantially in excess of 100%.
     For the fiscal year ended  November 30, 1999,  the portfolio  turnover rate
     for each Fund were approximately  400%. These rates vary year to year. High
     turnover  increases  transaction  costs and may  increase  taxable  capital
     gains.

We or the Fund refers to Core Fixed Income  Series ("Core Fixed Income Fund") or
Strategic Core Fixed Income Series ("Strategic Core Fixed Income Fund"),  each a
series of Lord Abbett Investment Trust (the "Company").

About each  Fund.  Each Fund is a  professionally  managed  portfolio  primarily
holding  securities  purchased  with the pooled  money of  investors.  The Funds
strive to reach their  stated  goals,  although  as with all funds,  they cannot
guarantee results.


2 The Funds
<PAGE>

MAIN RISKS

     These Funds are subject to the general risks and considerations  associated
     with investing in debt securities.  The value of an investment in each Fund
     will change as interest  rates  fluctuate in response to market  movements.
     When  interest  rates  rise,  the prices of debt  securities  are likely to
     decline,  and when interest rates fall, the prices of debt  securities tend
     to rise.

     The  mortgage-related  securities in which each Fund may invest,  including
     collateralized mortgage obligations ("CMOs"), may be particularly sensitive
     to changes in  prevailing  interest  rates.  The holders of the  underlying
     mortgages  may be  able  to  repay  principal  in  advance  and  may do so,
     especially when interest rates are falling.  When mortgages are prepaid,  a
     Fund may have to reinvest in  securities  with a lower  yield.  Conversely,
     principal  payments may arrive at a slower pace in times of rising interest
     rates.  The  Funds  may  then  be  unable  to  invest  in  higher  yielding
     securities.  These  circumstances  may result in lower  performance for the
     Funds.

     The  lower-rated  bonds in which the  Strategic  Core Fixed Income Fund may
     invest  involve  risks that the bond's  issuer  will not make  payments  of
     interest and  principal  payments  when due. Some issuers may default as to
     principal   and/or  interest   payments  after  the  Fund  purchases  their
     securities.  This may  result in losses to the Fund.  Also,  the market for
     high yield bonds generally is less liquid than the market for  higher-rated
     securities.

     The  Strategic  Core Fixed  Income  Fund may invest in foreign  securities.
     Investments in foreign securities may present increased market,  liquidity,
     currency, political, information and other risks.

     An  investment  in the Funds is not a bank  deposit  and is not  insured or
     guaranteed  by the  Federal  Deposit  Insurance  Corporation  or any  other
     government agency.  Each Fund is not a complete  investment program and may
     not be appropriate for all investors.  You could lose money by investing in
     the Funds.

You should read this entire prospectus, including "Other Investment Techniques,"
which concisely describes the other investment  strategies used by the Funds and
their risks.

                                                                     The Funds 3

PERFORMANCE

     The bar chart and  table  below  provide  some  indication  of the risks of
     investing  in the  Fund  by  illustrating  the  variability  of the  Fund's
     returns.  Each assumes  reinvestment  of dividends and  distributions.  The
     Fund's past  performance  is not  necessarily an indication of how the Fund
     will perform in the future.

     The bar chart shows changes in the performance of the Fund's Class Y shares
     from calendar year to calendar  year.  Performance  for Class A, B, C and P
     shares is not shown  because  those  classes  are new.  This chart does not
     reflect the sales charges  applicable  to Class A, B and C shares.  Returns
     for Class Y shares are  expected  to be  somewhat  higher than those of the
     Fund's Class A, B and C shares because Class Y shares have lower  expenses.
     If the sales charges were reflected, returns would be less.

     Returns for Class A, B and C shares will be somewhat  lower because Class Y
     shares have lower expenses.

(1)  A  contingent  deferred  sales  charge of 1.00% may be  assessed on certain
     redemptions  (a) of Class A shares  made  within  24 months  following  any
     purchases  made without a sales charge,  and (b) Class C shares if they are
     redeemed before the first anniversary of their purchase.

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

(3)  Because  12b-1 fees are paid out on an ongoing  basis,  over time they will
     increase  the cost of your  investment  and may cost you more  than  paying
     other types of sales charges.

Example
- --------------------------------------------------------------------------------

This  example is intended to help you compare the cost of  investing in the Fund
with the cost of investing in other mutual  funds.  This  example,  like that in
other  funds'  prospectuses,  assumes  that you  invest  $10,000  in the Fund at
maximum sales charge, if any, for the time periods indicated and then redeem all
of your shares at the end of those  periods.  The example also assumes that your
investment  has a 5% return  each year and that the  Fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your costs (including any applicable contingent deferred sales
charges) would be: Share class 1 Year 3 Years Class A shares $570 $772

- --------------------------------------------------------------------------------
Class B shares                                $666                       $814
- --------------------------------------------------------------------------------
Class C shares                                $266                       $514

- --------------------------------------------------------------------------------

You would have paid the following expenses if you did not redeem your shares:

Class A shares                                $570                       $772

- --------------------------------------------------------------------------------
Class C shares                                $166                       $514

- --------------------------------------------------------------------------------

Management fees are payable to Lord, Abbett & Co. ("Lord Abbett") for the Fund's
investment management.

12b-1 fees refer to fees incurred for activities that are primarily  intended to
result in the sale of Fund  shares  and  service  fees for  shareholder  account
service and maintenance.

Other  expenses  include fees paid for  miscellaneous  items such as shareholder
service fees and professional fees.

Lord Abbett is currently  waiving the management  fees and subsidizing the other
expenses of the Fund.  Accordingly,  the  expense  ratio of the Fund is 0%. Lord
Abbett may stop waiving the management  fees and  subsidizing the other expenses
at any time.

                                                                     The Funds 5

(1)  A  contingent  deferred  sales  charge of 1.00% may be  assessed on certain
     redemptions  (a) of Class A shares  made  within  24 months  following  any
     purchases  made without a sales charge,  and (b) Class C shares if they are
     redeemed before the first anniversary of their purchase.

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

(3)  Because  12b-1 fees are paid out on an ongoing  basis,  over time they will
     increase  the cost of your  investment  and may cost you more  than  paying
     other types of sales charges.

Example

- --------------------------------------------------------------------------------

This  example is intended to help you compare the cost of  investing in the Fund
with the cost of investing in other mutual  funds.  This  example,  like that in
other  Funds'  prospectuses,  assumes  that you  invest  $10,000  in the Fund at
maximum sales charge, if any, for the time periods indicated and then redeem all
of your shares at the end of those  periods.  The example also assumes that your
investment  has a 5% return  each year and that the  Fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your costs (including any applicable contingent deferred sales
charges) would be:

Share class                               1 Year                    3 Years
Class A shares                             $598                       $859
- --------------------------------------------------------------------------------
Class B shares                             $695                       $903
- --------------------------------------------------------------------------------
Class C shares                             $295                       $603
- --------------------------------------------------------------------------------
Class P shares                             $139                       $434
- --------------------------------------------------------------------------------

You would have paid the following expenses if you did not redeem your shares:

Class A shares                             $598                       $859
- --------------------------------------------------------------------------------
Class B shares                             $195                       $603
Class C shares                             $195                       $603
- --------------------------------------------------------------------------------
Class P shares                             $139                       $434
- --------------------------------------------------------------------------------

Management fees are payable to Lord Abbett for the Fund's investment management.

12b-1 fees refer to fees incurred for activities that are primarily  intended to
result in the sale of Fund  shares  and  service  fees for  shareholder  account
service and maintenance.

Other  expenses  include fees paid for  miscellaneous  items such as shareholder
service fees and professional fees.

Lord Abbett is currently  waiving the management  fees and subsidizing the other
expenses of the Fund.  Accordingly,  the  expense  ratio of the Fund is 0%. Lord
Abbett may stop waiving the management  fees and  subsidizing the other expenses
at any time.

                                                                     The Funds 7

PURCHASES

     The Fund offers in this prospectus four classes of shares: Classes A, B, C,
     and P, each with different expenses and dividends.  You may purchase shares
     at the net asset value ("NAV") per share  determined  after we receive your
     purchase  order  submitted in proper form. A front-end  sales charge may be
     added to the NAV in the case of the Class A shares.  There is no  front-end
     sales charge in the case of Class B, C and P shares,  although there may be
     a contingent deferred sales charge ("CDSC") as described below.

     You should read this section  carefully to determine  which class of shares
     represents the best investment option for your particular situation. It may
     not be suitable for you
     to place a  purchase  order  for Class B shares  of  $500,000  or more or a
     purchase order for Class C shares of $1,000,000 or more. You should discuss
     purchase options with your investment professional.

     For more information, see "Alternative Sales Arrangements" in the Statement
     of Additional Information.

     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 or change minimum investment requirements. All purchase orders are
     subject to our acceptance  and are not binding until  confirmed or accepted
     in writing.

NAV per share for each class of Fund shares is  calculated  each business day at
the close of regular  trading on the New York Stock Exchange  ("NYSE")  normally
4:00 p.m.  Eastern time.  Purchases and sales of Fund shares are executed at the
NAV next  determined  after the Fund  receives  your  order in proper  form.  In
calculating NAV, securities for which market quotations are available are valued
at those quotations.  Securities for which such quotations are not available are
valued at fair value under procedures approved by the Board of the Funds.

     See "Systematic  Withdrawal Plan" under "Services For Fund Investors" below
     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 the  purchase of such
     shares.

     Class P Shares.  Class P shares have lower annual expenses than Class B and
     Class C shares, no front-end sales charge,  and no CDSC. Class P shares are
     currently  sold and redeemed at NAV (a) pursuant to a Mutual Fund Fee Based
     Program, or (b) to the trustees of, or  employer-sponsors  with respect to,
     pension or retirement plans with at least 100 eligible employees (such as a
     plan under Section 401(a),  401(k) or 457(b) of the Internal  Revenue Code)
     which engage an investment  professional  providing or  participating in an
     agreement  to  provide   certain   recordkeeping,   administrative   and/or
     sub-transfer  agency  services  to  the  Fund  on  behalf  of the  Class  P
     shareholders.

SALES COMPENSATION

     As part of its plan for  distributing  shares,  each  Fund and Lord  Abbett
     Distributor pay sales and service  compensation to Authorized  Institutions
     that sell the Fund's shares and service its shareholder accounts.

     Sales compensation originates from two sources, as shown in the table "Fees
     and Expenses":  sales charges which are paid directly by shareholders;  and
     12b-1  distribution

CDSC,   regardless  of  Class,  is  not  charged  on  shares  acquired   through
reinvestment of dividends or capital gains  distributions  and is charged on the
original  purchase  cost or the current  market  value of the shares at the time
they are being sold, which-ever is lower. In addition,  repayment of loans under
Retirement  Plans and 403(b)  Plans will  constitute  new sales for  purposes of
assessing the CDSC.

To minimize  the amount of any CDSC,  the Fund redeems  shares in the  following
order:

1.   shares acquired by reinvestment of dividends and capital gains (always free
     of a CDSC)

2.   shares  held for six years or more (Class B) or two years or more after the
     month of purchases (Class A) or one year or more (Class C)

3.   shares  held the longest  before the sixth  anniversary  of their  purchase
     (Class B) or before  the  second  anniversary  after the month of  purchase
     (Class A) or before the first anniversary of their purchase (Class C)

10 Your Investment
<PAGE>


     fees  that  are  paid  out  of  the  Fund's  assets.  Service  compensation
     originates  from 12b-1  service  fees.  The total 12b-1 fees  payable  with
     respect to each share Class are .35% of Class A shares  (plus  distribution
     fees of up to 1.00% on certain qualifying purchases),  1.00% of Class B and
     C shares,  and .45% of Class P shares.  The amounts payable as compensation
     to Authorized Institutions,  such as your dealer, are shown in the chart at
     the end of this prospectus.  The portion of such  compensation paid to Lord
     Abbett  Distributor  is  discussed  under "Sales  Activities"  and "Service
     Activities."  Sometimes we do not pay  compensation  where tracking data is
     not  available  for certain  accounts or where the  Authorized  Institution
     waives part of the compensation.  In such cases, we may not require payment
     of any otherwise applicable CDSC.

     We may pay Additional  Concessions to Authorized  Institutions from time to
     time.

     Sales  Activities.  We may use 12b-1  distribution  fees to pay  Authorized
     Institutions to finance any activity which is primarily  intended to result
     in the sale of shares.  Lord  Abbett  Distributor  uses its  portion of the
     distribution fees attributable to the Fund's Class A and Class C shares for
     activities which are primarily intended to result in the sale of such Class
     A and Class C shares,  respectively.  These activities include, but are not
     limited  to,  printing  of   prospectuses   and  statements  of  additional
     information and reports for other than existing  shareholders,  preparation
     and distribution of advertising and sales material,  expenses of organizing
     and  conducting  sales  seminars,   Additional  Concessions  to  Authorized
     Institutions,  the cost necessary to provide distribution-related  services
     or  personnel,  travel,  office  expenses,  equipment  and other  allocable
     overhead.

     Service   Activities.   We  may  pay  12b-1   service  fees  to  Authorized
     Institutions  for any  activity  which is  primarily  intended to result in
     personal  service  and/or the  maintenance  of  shareholder  accounts.  Any
     portion of the service fees paid to Lord Abbett Distributor will be used to
     service and maintain shareholder accounts.

     You may purchase shares through any independent securities dealer who has a
     sales  agreement  with  Lord  Abbett  Distributor  or you can  fill out the
     attached  application and send it to the Funds at the address stated below.
     You should carefully read the paragraph below entitled "Proper Form" before
     placing your order to ensure that your order will be accepted.

     Name of the Fund
     P.O. Box 219100
     Kansas City, MO 64121

     By Exchange.  Telephone  the Funds at  800-821-5129  to request an exchange
     from any eligible Lord Abbett-sponsored fund.

     Proper Form. An order submitted  directly to the Funds must contain:  (1) a
     completed application, and (2) payment by check. When
     purchases are made by check, redemption

12b-1 fees are payable  regardless of expenses.  The amounts payable by the Fund
need not be directly related to expenses.  If Lord Abbett  Distributor's  actual
expenses  exceed the fee  payable to it, the Fund will not have to pay more than
that  fee.  If Lord  Abbett  Distributor's  expenses  are  less  than the fee it
receives, Lord Abbett Distributor will keep the full amount of the fee.

Exchange  Limitations.  Exchanges should not be used to try to take advantage of
short-term swings in the market.  Frequent  exchanges create higher expenses for
the Funds. Accordingly,  the Funds reserve the right to limit or termi-nate this
privilege  for  any  share-holder  making  frequent  exchanges  or  abusing  the
privilege.  The Funds also may revoke the privilege for all shareholders upon 60
days' written notice.

                                                              Your Investment 11

     proceeds will not be paid until the Funds or transfer agent is advised that
     the check has  cleared,  which may take up to 15  calendar  days.  For more
     information call the Funds at 800-821-5129.

REDEMPTIONS

     By Broker.  Call your investment  professional  for  instructions on how to
     redeem your shares.

     By  Telephone.  To obtain the proceeds of a  redemption  of $50,000 or less
     from your  account,  you or your  representative  should  call the Funds at
     800-821-5129.

     By Mail.  Submit a written  redemption  request  indicating  the name(s) in
     which the account is registered, the Fund's name, the Class of shares, your
     account number, and the dollar value or number of shares you wish to sell.

     Include all necessary signatures. 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 call 800-821-5129.

     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
     three business days after receipt of your redemption request.  Your account
     balance  must be  sufficient  to cover the amount  being  redeemed  or your
     redemption order will not be processed.  Under unusual  circumstances,  the
     Fund may suspend redemptions, or postpone payment for more than seven days,
     as permitted by federal securities laws.

     To determine if a CDSC applies to a  redemption,  see "Class A share CDSC,"
     "Class B share CDSC" or "Class C share CDSC."

DISTRIBUTIONS AND TAXES

     Each Fund normally pays its shareholders  dividends from its net investment
     income and  distributes  its net capital  gains (if any) as "capital  gains
     distributions" on an annual basis. Your distributions will be reinvested in
     the Fund unless you instruct the Fund to pay them to you in cash. There are
     no sales charges on  reinvestments.  The tax status of distributions is the
     same for all  shareholders  regardless  of how long  they have  owned  Fund
     shares or whether distributions are reinvested or paid in cash.

     Except in tax-advantaged accounts, any sale, redemption or exchange of Fund
     shares may be taxable to the shareholder.

     Information on the tax treatment of distributions,  including the source of
     dividends and distributions of capital gains by the Fund, will be mailed to
     shareholders  each year.  Because  everyone's tax situation is unique,  you
     should  consult your tax adviser  regarding the treatment of  distributions
     under the federal, state and local tax rules that apply to you.


Small Accounts.  Our Board may authorize  closing any account in which there are
fewer than 25 shares if it is in the Funds' best interest to do so.


Eligible Guarantor is any broker or bank that is a member of the medallion stamp
program.  Most major securities  firms and banks are members of this program.  A
notary public is not an Eligible Guarantor.

OTHER INVESTMENT TECHNIQUES

     This section describes some of the investment techniques that might be used
     by each Fund and their risks.

     Adjusting Investment  Exposure.  Each Fund may, but is not required to, use
     various strategies to change its investment  exposure to adjust to changing
     security prices, inter-est rates, currency exchange rates, commodity prices
     and  other  factors.   These  strategies  may  involve  buying  or  selling
     derivative  instruments,  such as options and futures  contracts,  stripped
     securities,  currency exchange contracts,  swap agreements,  short sales of
     securities,  indexed securities and rights and warrants.  Each Fund may use
     these  transactions to change the risk and return  characteristics  of each
     Fund's  portfolio.  If we  judge  market  conditions  incorrectly  or use a
     strategy that does not correlate well with the Fund's investments, it could
     result in a loss,  even if we intended  to lessen risk or enhance  returns.
     These  transactions  may involve a small investment of cash compared to the
     magnitude of the risk assumed and could produce  disproportionate  gains or
     losses.  Also,  these strategies could result in losses if the counterparty
     to a transaction does not perform as promised.

     Foreign Currency Transactions. The Strategic Core Fixed Income Fund may use
     currency  forwards  and  options to hedge the risk to the  portfolio  if it
     expects that foreign  exchange price movements will be unfavorable for U.S.
     investors.  Generally,  these  instruments  allow  the  Fund  to  lock in a
     specified exchange rate for a period of time. If the Fund's forecast proves
     to be wrong,  such a hedge may cause a loss.  Also,  it may be difficult or
     impractical  to hedge  currency risk in many emerging  countries.  The Fund
     generally  will not enter into a forward  contract with a term greater than
     one year.  Under  some  circumstances,  the Fund may  commit a  substantial
     portion or the entire value of its  portfolio to the  completion of forward
     contracts.  Although such  contracts  will be used  primarily to attempt to
     protect the Fund from adverse  currency  movements,  their use involves the
     risk Lord Abbett will not accurately  predict currency  movements,  and the
     Fund's return could be reduced.

     Foreign  Securities.  The Strategic Core Fixed Income Fund may invest up to
     20% of its  net  assets  in  foreign  securities.  Foreign  securities  are
     securities primarily traded in countries outside the United States. Foreign
     markets  and the  securities  traded  in them are not  subject  to the same
     degree of regulation as U.S. markets.  Securities  clearance and settlement
     procedures may be different in foreign countries. There may be less trading
     volume in foreign  markets,  subjecting  the  securities  traded in them to
     higher  price  fluctuations.  Transaction  costs may be  higher in  foreign
     markets.  The Fund may hold foreign securities which trade on days when the
     Fund does not sell shares.  As a result,  the value of the Fund's portfolio
     securities  may change on days an  investor  may not  purchase or sell Fund
     shares.

     Foreign issuers are generally not subject to similar,  uniform  accounting,
     auditing and financial  reporting  requirements  as U.S.  issuers.  Foreign
     investments  may be  affected  by changes  in  currency  rates or  currency
     controls.  Certain foreign countries may limit the Fund's ability to remove
     its assets from the  country.  With respect to certain  foreign  countries,
     there is a possibility of  nationalization,  expropriation  or confiscatory
     taxation, imposition of withholding or other taxes, and political or social
     instability which could affect investments in those countries.

                                                         For More Information 15

<PAGE>

     High Yield Debt Securities.  High yield debt securities or "junk bonds" are
     rated  BB/Ba or lower or  unrated  and  typically  pay a higher  yield than
     investment grade debt securities. These bonds have a higher risk of default
     than investment grade bonds and their prices can be much more volatile.

     Investment Grade Debt Securities. These are debt securities which are rated
     in one of the four highest grades  assigned by Moody's  Investors  Service,
     Inc., Standard & Poor's Ratings Services or Fitch Investors Service, or are
     unrated but determined by Lord Abbett to be equivalent in quality.

     Mortgage-Backed   Securities.   These  securities  directly  or  indirectly
     represent a participation in, or are secured by and payable from,  mortgage
     loans secured by real property. The price of a mortgage-backed security may
     be   significantly   affected   by  changes   in   interest   rates.   Some
     mortgage-backed  securities  have  structures  that make their  reaction to
     interest rates and other factors difficult to predict,  making their prices
     very volatile.

     Futures  Contracts  and Options  Transactions.  Each Fund may  purchase and
     write put and call options on  securities  or stock indices that are traded
     on  national   securities   exchanges  and  enter  into  financial  futures
     transactions.

     A put  option  gives the  buyer of the  option  the right to sell,  and the
     seller of the option  the  obligation  to buy,  the  underlying  instrument
     during the option period.

     A call  option  gives the  buyer of the  option  the right to buy,  and the
     writer  (seller)  of the  option the  obligation  to sell,  the  underlying
     instrument.  Each Fund may write (sell) only "covered" options.  This means
     that the Fund may only sell call options on securities which the Fund owns.
     When a Fund writes a call option it gives up the  potential for gain on the
     underlying  securities in excess of the exercise price of the option during
     the period that the option is open.

     A financial futures  transaction is an  exchange-traded  contract to buy or
     sell a standard quantity and quality of a financial  instrument or index at
     a specific  future date and price.  Each Fund may purchase and sell futures
     contracts and options thereon.

     Each Fund may write (sell)  covered call options and secured put options on
     up to 25% of its net  assets  and may  purchase  put and call  options  and
     purchase and sell futures  contracts  provided  that no more than 5% of its
     net assets (at the time of purchase)  would be invested in premiums on such
     options and initial margin deposits on such futures contracts.

     Risks of  Futures  Contracts  and  Options  Transactions.  Transactions  in
     derivative  instruments  such as  futures,  options  on  futures  and other
     options  involve  additional  risk of loss.  Loss may result from a lack of
     correlation  between changes in the value of these  derivative  instruments
     and the Fund's  assets  being  hedged,  the  potential  illiquidity  of the
     markets  for  derivative  instruments,  or the risks  arising  from  margin
     requirements   and   related   leverage   factors   associated   with  such
     transactions. The use of these investment techniques also involves the risk
     of loss if the  portfolio  managers are incorrect in their  expectation  of
     fluctuations  in  securities  prices.  In  addition,  the loss  that may be
     incurred by the Fund in entering into futures contracts and in writing call
     options on futures is  potentially  unlimited  and may exceed the amount of
     the premium received.

     Repurchase Agreements. Each Fund may enter into Repurchase Agreements. In a
     Repurchase  Agreement,  a  Fund  buys  a  security  at  one  price  from  a
     broker-dealer or financial  institution and  simultaneously  agrees to sell
     the same  security  back to the same party at a higher price in the future.
     If the other party to the agreement defaults or becomes  insolvent,  a Fund
     could lose money.

16 For More Information

<PAGE>

     Reverse Repurchase Agreements.  Each Fund may enter into reverse repurchase
     agreements. In a reverse repurchase agreement, a Fund sells a security to a
     securities  dealer or bank for cash and also agrees to repurchase  the same
     security later at a set price. Reverse repurchase  agreements expose a Fund
     to cre dit risk  (that  is,  the risk  that the  counterparty  will fail to
     resell the security to the Fund),  but this risk is greatly reduced because
     the Fund  receives  cash equal to 100% of the price of the  security  sold.
     Engaging  in reverse  repurchase  agreements  may also  involve  the use of
     leverage,  in that the Fund may reinvest the cash it receives in additional
     securities.  Each Fund will  attempt to minimize  this risk by managing its
     duration. A Fund's reverse repurchase agreements will not exceed 20% of the
     Fund's net assets.

     Short  Sales.  Each Fund may make short sales of  securities  or maintain a
     short  position,  provided that at all times when a short  position is open
     the Fund owns an equal amount of such securities or securities  convertible
     into or exchangeable,  without payment of any further consideration, for an
     equal amount of the  securities of the same issuer as the  securities  sold
     short.  Each  Fund does not  intend to have more than 5% of its net  assets
     (determined  at the time of the short sale)  subject to short sales against
     the  box.  A short  sale is  against  the box to the  extent  that the Fund
     contemporaneously  owns  or has  the  right  to  obtain  at no  added  cost
     securities identical to those sold short.

     U.S.  Government  Securities.  U.S.  government  securities are obligations
     issued  or   guaranteed   by  the  U.S.   government,   its   agencies   or
     instrumentalities.

     When-Issued or Delayed Delivery Securities.  Each Fund may purchase or sell
     securities  with  payment and  delivery  taking place as much as a month or
     more later. A Fund would do this in an effort to buy or sell the securities
     at an advantageous price and yield. The securities  involved are subject to
     market  fluctuation  and no interest  accrues to the  purchaser  during the
     period  between  purchase  and  settlement.  At the time of delivery of the
     securities, their market value may be less than the purchase price.

GLOSSARY OF SHADED TERMS

     Additional Concessions. Lord Abbett Distributor may, for specified periods,
     allow  dealers to retain  the full sales  charge for sales of shares or may
     pay an  additional  con-  cession  to a dealer  who sells a minimum  dollar
     amount of our shares and/or shares of other Lord Abbett-sponsored funds. In
     some instances, such additional concessions will
     be offered only to certain dealers expected to sell significant  amounts of
     shares.  Additional payments may be paid from Lord Abbett Distributor's own
     resources or from  distribution  fees received from a fund and will be made
     in the form of cash or,  if  permitted,  non-cash  payments.  The  non-cash
     payments will include  business  seminars at Lord Abbett's  headquarters or
     other  locations,  including  meals and  entertainment,  or the  receipt of
     merchandise.  The cash  payments  may include  payment of various  business
     expenses of the dealer.

     In  selecting  dealers to  execute  portfolio  transactions  for the Fund's
     portfolio,  if two or more dealers are considered capable of obtaining best
     execution,  we may prefer the dealer who has sold our shares  and/or shares
     of other Lord Abbett-sponsored Funds.

     Authorized  Institutions.  Institutions  and  persons  permitted  by law to
     receive  service  and/or  distribution  fees  under a Rule  12b-1  Plan are
     "Authorized   Institutions."  Lord  Abbett  Distributor  is  an  Authorized
     Institution.

     Eligible  Fund. An Eligible Fund is any Lord  Abbett-sponsored  fund except
     for  (1)  certain  tax-free,   single-state   funds  where  the  exchanging
     shareholder  is a resident  of a state in which such a fund is not  offered
     for sale; (2) Lord Abbett Equity Fund; (3)

                                                         For More Information 17

<PAGE>

     Lord Abbett Series Fund; (4) Lord Abbett U.S.  Government  Securities Money
     Market Fund ("GSMMF")  (except for holdings in GSMMF which are attributable
     to any shares exchanged from the Lord Abbett Family of Funds).  An Eligible
     Fund also is any  Authorized  Institution's  affiliated  money  market Fund
     satisfying Lord Abbett  Distributor as to certain omnibus account and other
     criteria.

     Eligible Mandatory Distributions.  If Class B shares represent a part of an
     individual's total IRA or 403(b)  investment,  the CDSC will be waived only
     for that part of a mandatory  distribution which bears the same relation to
     the entire  mandatory  distribution as the B share  investment bears to the
     total investment.

     Legal Capacity.  With respect to a redemption request, if (for example) the
     request is on behalf of the estate of a deceased shareholder,  John W. Doe,
     by a person  (Robert  A.  Doe) who has the  legal  capacity  to act for the
     estate  of the  deceased  shareholder  because  he is the  executor  of the
     estate,  then the  request  must be  executed  as  follows:  Robert  A.Doe,
     Executor of the Estate of John W. Doe. That  signature  using that capacity
     must be guaranteed by an Eligible Guarantor.

     Similarly,  if (for example) the redemption request is on behalf of the ABC
     Corporation by a person (Mary B. Doe) that has the legal capacity to act on
     behalf  of  this   corporation,   because  she  is  the  President  of  the
     corporation,  then the request must be executed as follows: ABC Corporation
     by Mary  B.Doe,  President.  That  signature  using that  capacity  must be
     guaranteed by an Eligible Guarantor (see example in right column).

     Mutual Fund Fee Based Program.  Certain  unaffiliated  authorized  brokers,
     dealers,  registered  investment  advisers or other financial  institutions
     ("entities")   who  either  (1)  have  an  arrangement   with  Lord  Abbett
     Distributor in accordance  with certain  standards  approved by Lord Abbett
     Distributor,  providing  specifically  for  the  use  of  our  shares  (and
     sometimes providing for acceptance of orders for such shares on our behalf)
     in particular  investment  products made  available for a fee to clients of
     such entities, or (2) charge an advisory, consulting or other fee for their
     services  and buy shares for their own  accounts  or the  accounts of their
     clients.

     Purchaser.  The  term  "purchaser"  includes:  (1)  an  individual,  (2) an
     individual  and his or her spouse and children under the age of 21, and (3)
     a trustee or other fiduciary purchasing shares for a single trust estate or
     single fiduciary  account  (including a pension,  profit-sharing,  or other
     employee  benefit trust qualified under Section 401 of the Internal Revenue
     Code - more than one qualified employee benefit trust of a single employer,
     including its consolidated subsidiaries,  may be considered a single trust,
     as may qualified  plans of multiple  employers  registered in the name of a
     single bank trustee as one account),  although more than one beneficiary is
     involved.

     Special  Retirement  Wrap  Program.  A program  sponsored by an  Authorized
     Institution showing one or more  characteristics  distinguishing it, in the
     opinion of Lord Abbett  Distributor,  from a Mutual Fund Fee Based Program.
     Such  characteristics  include,  among  other  things,  the  fact  that  an
     Authorized Institution does not charge its clients any fee of
      a consulting  or advisory  nature that is  economically  equivalent to the
     distribution fee under the Class A 12b-1 Plan and the fact that the program
     relates to participant- directed Retirement Plans.


GUARANTEED SIGNATURE. An acceptable form of guarantee would be as follows:

  In the case of the estate --

    Robert A. Doe
    Executor of the Estate of
    John W. Doe

    [Date]

             SIGNATURE GUARANTEED

RECENT PERFORMANCE

     The  following is a discussion of recent  performance  for the twelve month
     period ending November 30, 1999.

     For the period under review the Funds,  outperformed  their benchmark,  the
     Lehman  Aggregate  Bond  Index.  The Funds'  outperformance  can be largely
     attributed to their continued  focus on what are termed "spread  products,"
     which include Freddie Macs (FHLMCs),  corporate debentures,  and commercial
     mortgage-backed securities (CMBS).

     These securities offer a higher yield than Treasuries, which in itself adds
     performance  to the  portfolios.  More  importantly,  this yield  advantage
     varies over time and our  tactical  portfolio  adjustments  added  relative
     capital  appreciation  to the Funds.  For example,  as the yield  advantage
     increased (securities underperformed Treasuries), we added to our holdings,
     only  to  sell  these  securities  after  the  yield  advantage  contracted
     (securities outperformed Treasuries).

     The Federal  Reserve Board (the "Fed") has increased  interest  rates three
     times since June, 1999, in an attempt to moderate  economic  growth.  As of
     yet, there are few signs that these actions have taken hold. Should the Fed
     continue on its  "tightening  path",  interest rates will rise and economic
     growth is likely  to slow.  As a result,  our  interest  rate  exposure  is
     neutral to the market (i.e., about a 5 year duration).

     performance of the index is not  necessarily  representative  of the Fund's
     performance.

(2)  The inception date for the Class Y is 12/10/97.

(3)  This shows total  return  which is the percent  change in net asset  value,
     with all  dividends  and  distributions  reinvested  for the periods  shown
     ending November 30, 1999 using the  SEC-required  uniform method to compute
     total return.  Because Class A, B, C and P shares have less than on year of
     performance  the total  returns  shown are for Class Y shares.  Returns for
     Class A, B, C and P share are  expected to be somewhat  lower that those of
     Class Y shares because Class A, B, C and P shares have higher expenses.

(1)  The service fee for Class A shares is paid quarterly and for Class A shares
     may not exceed 0.15% if sold prior to  September 1, 1985.  The first year's
     service fee on Class B and C shares is paid at the time of sale.

(2)  Reallowance/concession   percentages   and  service  fee   percentages  are
     calculated  from  different  amounts,  and  therefore  may not equal  total
     compensation  percentages  if combined  using simple  addition.  Additional
     Concessions  may be paid to Authorized  Institutions,  such as your dealer,
     from time to time.

(3)  Concessions  are paid at the time of sale on all Class A shares sold during
     any  12-month  period  starting  from the day of the first net asset  value
     sale.  With  respect to (a) Class A share  purchases at $1 million or more,
     sales  qualifying at such level under rights of accumulation and Letters of
     Intention  privileges  are  included  and (b) for Special  Retirement  Wrap
     Programs,  only new  sales are  eligible  and  exchanges  into the Fund are
     excluded. Certain purchases of Class A shares are subject to a CDSC.

(4)  Class B and C shares are subject to CDSCs.

(5)  With  respect  to  Class  B,  C and  P  shares,  0.25%,  0.90%  and  0.45%,
     respectively,  of the  average  annual  net  asset  value  of  such  shares
     outstanding during the quarter (including distribution  reinvestment shares
     after  the  first  anniversary  of their  issuance)  is paid to  Authorized
     Institutions.  These fees are paid  quarterly  in  arrears.  In the case of
     Class C shares for fixed-income Funds, such as U.S.  Government  Securities
     Fund,  0.10% of the  average  net asset value of such shares is retained by
     Lord Abbett Distributor,  thus reducing from 0.75% to 0.65% after the first
     year.  Lord,  Abbett & Co. uses 0.10% for  expenses  primarily  intended to
     result in the sale of such Funds' shares.

Item 25. Indemnification

         The Registrant is a Delaware  Business Trust  established under Chapter
         38 of Title 12 of the Delaware Code. The  Registrant's  Declaration and
         Instrument  of Trust at Section  4.3  relating  to  indemnification  of
         Trustees, officers, etc. states the following.

         The Trust shall indemnify each of its Trustees, officers, employees and
         agents (including any individual who serves at its request as director,
         officer,  partner, trustee or the like of another organization in which
         it has any interest as a  shareholder,  creditor or otherwise)  against
         all liabilities and expenses, including but not limited to amounts paid
         in satisfaction of judgments,  in compromise or as fines and penalties,
         and counsel fees  reasonably  incurred by him or her in connection with
         the defense or  disposition  of any action,  suit or other  proceeding,
         whether  civil or  criminal,  before  any  court or  administrative  or
         legislative body in which he or she may be or may have been involved as
         a party or  otherwise  or with  which he or she may be or may have been
         threatened, while acting as Trustee or as an officer, employee or agent
         of the Trust or the  Trustees,  as the case may be, or  thereafter,  by
         reason  of his or her being or having  been  such a  Trustee,  officer,
         employee or agent,  except with respect to any matter as to which he or
         she shall have been  adjudicated not to have acted in good faith in the
         reasonable  belief that his or her action was in the best  interests of
         the Trust or any Series thereof. Notwithstanding anything herein to the
         contrary,  if any  matter  which  is  the  subject  of  indemnification
         hereunder  relates  only to one Series (or to more than one but not all
         of the Series of the Trust),  then the indemnity shall be paid only out
         of  the  assets  of  the  affected  Series.   No  individual  shall  be
         indemnified  hereunder against any liability to the Trust or any Series
         thereof  or the  Shareholders  by reason of  willful  misfeasance,  bad
         faith, gross negligence or reckless disregard of the duties involved in
         the conduct of his or her office. In addition,  no such indemnity shall
         be provided  with respect to any matter  disposed of by settlement or a
         compromise  payment  by  such  Trustee,  officer,  employee  or  agent,
         pursuant to a consent  decree or otherwise,  either for said payment or
         for any other expenses unless there has been a determination  that such
         compromise is in the best interests of the Trust or, if appropriate, of
         any affected  Series thereof and that such Person appears to have acted
         in good faith in the  reasonable  belief  that his or her action was in
         the best  interests  of the Trust or, if  appropriate,  of any affected
         Series thereof, and did not engage in willful  misfeasance,  bad faith,
         gross  negligence or reckless  disregard of the duties  involved in the
         conduct of his or her office.  All  determinations  that the applicable
         standards of conduct have been met for indemnification  hereunder shall
         be made by (a) a majority vote of a quorum  consisting of disinterested
         Trustees   who  are  not   parties  to  the   proceeding   relating  to
         indemnification,  or (b) if such a quorum is not obtainable or, even if
         obtainable,   if  a  majority  vote  of  such  quorum  so  directs,  by
         independent  legal  counsel  in a  written  opinion,  or (c) a vote  of
         Shareholders  (excluding Shares owned of record or beneficially by such
         individual).  In addition,  unless a matter is disposed of with a court
         determination (i) on the merits that such Trustee, officer, employee or
         agent was not liable or (ii) that such Person was not guilty of willful
         misfeasance,  bad faith,  gross negligence or reckless disregard of the
         duties involved in the conduct of his or her office, no indemnification
         shall be provided  hereunder  unless there has been a determination  by
         independent legal counsel in a written opinion that such Person did not
         engage in willful misfeasance,  bad faith, gross negligence or reckless
         disregard of the duties involved in the conduct of his or her office.


                                       2

         The Trustees  may make advance  payments out of the assets of the Trust
         or, if  appropriate,  of the  affected  Series in  connection  with the
         expense of defending  any action with respect to which  indemnification
         might be sought  under  this  Section  4.3.  The  indemnified  Trustee,
         officer,  employee  or  agent  shall  give  a  written  undertaking  to
         reimburse  the  Trust or the  Series  in the  event it is  subsequently
         determined that he or she is not entitled to such  indemnification  and
         (a) the indemnified Trustee,  officer,  employee or agent shall provide
         security  for his or her  undertaking,  (b) the Trust  shall be insured
         against losses arising by reason of lawful advances,  or (c) a majority
         of a quorum of disinterested  Trustees or an independent  legal counsel
         in a written  opinion  shall  determine,  based on a review of  readily
         available facts (as opposed to a full trial-type  inquiry),  that there
         is reason  to  believe  that the  indemnitee  ultimately  will be found
         entitled  to  indemnification.  The  rights  accruing  to any  Trustee,
         officer, employee or agent under these provisions shall not exclude any
         other right to which he or she may be lawfully entitled and shall inure
         to the benefit of his or her heirs, executors,  administrators or other
         legal representatives.

         Insofar as  indemnification  for liability arising under the Securities
         Act of 1933 may be  permitted to  Trustees,  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 Trustee,  officer or  controlling  person of the Registrant in the
         successful  defense of any action,  suit or  proceeding) is asserted by
         such Trustee,  officer or  controlling  person in  connection  with the
         securities being registered, 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.

         Lord,  Abbett & Co.  acts as  investment  adviser  for the Lord  Abbett

Dear Sirs:

     You have requested our opinion in connection  with your filing of Amendment
No. 27 to the Registration  Statement on Form N-1A (the  "Amendment")  under the
Investment Company Act of 1940, as amended, of Lord Abbett Investment Trust, a
Delaware  business  trust (the  "Company"),  and in  connection  therewith  your
registration of the following shares of beneficial interest,  without par value,
of the Company (collectively,  the "Shares"): Core Fixed Income Fund (Classes
A, B, C, and P) and Strategic Core Fixed Income Fund (Classes A, B, C and P).

     We have  examined  and relied upon  originals,  or copies  certified to our
satisfaction,  of  such  company  records,  documents,  certificates  and  other
instruments  as in our judgment are  necessary  or  appropriate  to enable us to
render the opinion set forth below.

     We are of the opinion  that the Shares  issued in the  continuous  offering
have been duly authorized  and,  assuming the issuance of the Shares for cash at
net asset value and receipt by the Company of the consideration therefore as set
forth in the  Amendment,  the  Shares  will be  validly  issued,  fully paid and
nonassessable.

     We express no opinion as to matters  governed  by any laws other than Title
12 of the  Delaware  Code.  We consent to the filing of this  opinion  solely in
connection  with the Amendment.  In giving such consent,  we do not hereby admit
that we come within the  category  of persons  whose  consent is required  under
Section  7 of  the  Securities  Act of  1933,  as  amended,  or  the  rules  and
regulations of the Securities and Exchange Commission thereunder.

                                            Very truly yours,


                                            WILMER, CUTLER & PICKERING

                             - Strategic Core Fixed Income Series
Class A Shares


     RULE 12b1 DISTRIBUTION PLAN AND AGREEMENT dated as of March 15, 2000 by and
between LORD ABBETT INVESTMENT TRUST, a Delaware business trust (the "Fund"), on
behalf of the Core Fixed Income Series and Strategic Core Fixed Income Series
(each a "Series"), 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 Series' Class A shares (the  "Shares")  pursuant to the
Distribution  Agreement  between the Fund and the Distributor,  dated as of the
date hereof (the "Distribution Agreement").

     WHEREAS,  the Fund desires to adopt a Distribution  Plan and Agreement (the
"Plan") for the Series with the Distributor,  as permitted by Rule 12b1 under
the Act,  pursuant to which the Series may make certain payments to the
Distributor to be used by the
Distributor  or paid to  institutions  and persons  permitted by applicable  law
and/or rules to receive such payments ("Authorized  Institutions") in connection
with sales of Shares  and/or  servicing  of  accounts  of  shareholders  holding
Shares.

     WHEREAS,  the  Fund's  Board of  Trustees  has  determined  that there is a
reasonable likelihood that the Plan will benefit the Series 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, and
subject to the provisions of paragraph 8 of this Plan, 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 each Series in order to provide additional 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.

     2. The Fund also hereby authorizes the Distributor to use payments received
hereunder from each Series in order to(a)finance any activity which is primarily
intended to result in the sale of Shares and (b) provide continuing  information
and  investment  services to  shareholder  accounts not  serviced by  Authorized
Institutions  receiving  a  service  fee  from  the  Distributor  hereunder  and
otherwise to encourage such accounts to remain invested in the Shares;  provided
that (i) any payments  referred to in the foregoing  clause (a) shall not exceed
the  distribution fee permitted to be paid at the time under paragraph 3 of this
Plan and shall be  authorized  by the Board of Trustees of the Fund by a vote of
the kind referred to in paragraph 10 of this Plan and (ii) any payments referred
to in clause (b) shall not exceed the  service fee  permitted  to be paid at the
time under paragraph 3 of this Plan.


     3.Each Series is authorized to pay the Distributor hereunder for remittance
to Authorized Institutions and/or use by the Distributor pursuant to this Plan
(a) service fees and (b) distribution fees, each at an annual rate not to exceed
 .25 of 1% of the average annual net asset value of Shares outstanding. The Board
of Trustees of the Fund shall from time to time  determine  the amounts,  within
the  foregoing  maximum  amounts,  that each Series  may  pay  the  Distributor
hereunder.  Any such fees (which may be waived by the Authorized Institutions in
whole or in part) may be  calculated  and paid  quarterly or more  frequently if
approved by the Board of Trustees of the Fund. Such determinations and approvals
by the Board of Trustees  shall be made and given by votes of the kind  referred
to in paragraph 10 of this Plan. Payments by holders of Shares to each Series of
contingent deferred  reimbursement charges relating to distribution fees paid by
each Series hereunder shall reduce the amount of distribution  fees for purposes
of the annual 0.25%  distribution  fee limit.  The Distributor  will monitor the
payments  hereunder  and shall reduce such  payments or take such other steps as
may be necessary to assure that (i) the payments  pursuant to this Plan shall be
consistent with Rule 2830,  subparagraphs (d)(2) and (5) of the Conduct 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 (ii)each Series 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 or shares
sold by)  such  Authorized  Institution  and held in an  account  covered  by an
Agreement.

     4. The net asset value of the Shares shall be determined as provided in the
Declaration and Agreement of Trust of the Fund. If the Distributor waives all or
a  portion  of  the fees  which are to be  paid  by each Series  hereunder,  the
Distributor  shall not be deemed to have waived its rights under this  Agreement
to have each Series 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 each Series hereunder and shall provide to the Fund's Board of
Trustees, and the Trustees 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   Trustees,   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
Trustees,   officers,   partners,   members  or  other  representatives  of  the
Distributor  are or may be  "interested  persons"  of the  Fund,  except  as may
otherwise be provided in the Act.

     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, each Series or any of the shareholders
, creditors, trustees, or officers of the Fund; provided however, that nothing
herein shall be deemed to protect the  Distributor against any  liability to the
Fund or each Series' 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  upon the date  hereof,  and shall
continue  in  effect  for a period  of more than one year from that date only so
long as such continuance is specifically approved at least annually by a vote of
the Board of  Trustees  of the Fund,  including  the vote of a  majority  of the
trustees who are not "interested  persons" of the Fund and who have no direct or
indirect  financial  interest in the  operation of 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 each Series hereunder above the maximum amounts referred to in
paragraph 3 of this Plan without a shareholder vote in compliance with Rule
12b-1 and Rule 18f-3 under the Act as in effect at such time, and each material
amendment must be approved by a vote of the Board of Trustees of the Fund,
including the vote of a majority of the Trustees who are not "interested
persons" of the Fund and who have no direct or indirect financial interest in
the operation of 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.
Amendments to this Plan which do not increase  materially  the  amount  to be
spent by each Series hereunder above the maximum  amounts referred to in
paragraph 3 of this Plan may be made pursuant to paragraph 10 of this Plan.

     10.  Amendments  to this Plan other than  material  amendments  of the kind
referred to in the foregoing paragraph9 may be adopted by a vote of the Board of
Trustees of the Fund,  including  the vote of a majority of the Trustees who are
not  "interested  persons"  of the  Fund  and who  have no  direct  or  indirect
financial  interest in the operation of this Plan or in any agreement related to
this Plan. The Board of Trustees 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  (a) by the vote of a majority  of the  trustees 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 the 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 Trustees of the Fund who are not "interested persons" of the
Fund are committed to the discretion of such disinterested  Trustees.  The terms
"interested  persons,"  "assignment"  and "vote of a majority of the outstanding
voting  securities"  shall have the same  meanings as those terms are defined in
the Act.

     13. The obligations of the Fund and each Series, including those imposed
hereby, are not personally binding upon, nor shall resort be had to the private
property of, any of the trustees, shareholders, officers, employees or agents of
the Fund or Series individually, but are binding only upon the assets and
property of the Fund or Series. Any and all personal liability, either at common
law or in equity, or by statute or constitution, of every such trustee,
shareholder, officer, employee or agent for any breach of the Fund or Series of
any agreement, representation or warranty hereunder is hereby expressly waived
as a condition of and in consideration for the execution of this Agreement by
the Fund.

     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.

           Rule 12b-1 Distribution Plan and Agreement
    Lord Abbett Investment Trust - Core Fixed Income Series
               -Strategic Core Fixed Income Series
                         Class B Shares

     RULE 12b-1 DISTRIBUTION PLAN AND AGREEMENT dated as of March
15, 2000, by and between LORD ABBETT INVESTMENT TRUST, a Delaware
business  trust (the "Fund"), on behalf of the Core Fixed  Income
Series  and Strategic Core Fixed Income Series (each a "Series"),
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
Fund's Class B shares (the "Shares") pursuant to the Distribution
Agreement between the Fund and the Distributor, dated as  of  the
date hereof, and

     WHEREAS,  the Fund desires to adopt a Distribution Plan  and
Agreement (the "Plan") with the Distributor, as permitted by Rule
12b-1  under  the  Act, pursuant to which each  Series  may  make
certain  payments  to the Distributor (a) to help  reimburse  the
Distributor  for the payment of sales commissions to institutions
and  persons permitted by applicable law and/or rules to  receive
such  payments  ("Authorized Institutions")  in  connection  with
sales  of  Shares and (b) for use by the Distributor in rendering
service  to the Fund, including paying and financing the  payment
of   sales   commissions,  service  fees,  and  other  costs   of
distributing  and selling Shares as provided in  paragraph  3  of
this Plan, and

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

     NOW, THEREFORE, in consideration of the mutual covenants and
of  other  goods 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  (a)  sales commissions (particularly those paid  or  financed
with  payments received hereunder) and (b) service fees  received
hereunder  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, respectively. 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 reductions as provided  below  in
this paragraph 2, each Series periodically, as determined by  the
Fund's Board of Trustees (in the manner contemplated in paragraph
11),  shall pay to the Distributor fees (a) for services,  at  an
annual  rate  not to exceed .25 of 1% of the average  annual  net
asset value of Shares outstanding and (b) for distribution, at an
annual  rate  not to exceed .75 of 1% of the average  annual  net
asset  value  of Shares outstanding.  Payments will be  based  on
Shares  outstanding  during any such period.  Shares  outstanding
include Shares issued for reinvested dividends and distributions.
The  Board  of  Trustees  of the Fund shall  from  time  to  time
determine the amounts, within the foregoing maximum amounts, that
each   Series   may   pay   the   Distributor   hereunder.   Such
determinations by the Board of Trustees shall be made by votes of
the  kind  referred to in paragraph 11 of this Plan. The  service
fees  mentioned in this paragraph are for the purposes  mentioned
in  clause  (b)  (ii)  of  paragraph  1  of  this  Plan  and  the
distribution  fees  mentioned  in  this  paragraph  are  for  the
purposes mentioned in clause (b) (i) of paragraph 1 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 Article III, Section 26, subparagraphs (d)(2) and
(5) of the Rules of Fair Practice 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 Fund 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.     The   Distributor   may  use  amounts   received   as
distribution  fees hereunder from each Series to engage  directly
or  indirectly  in  financing  any activity  which  is  primarily
intended  to  result  in the sale of Shares  including,  but  not
limited  to:  (a) paying and financing the payment of commissions
or  other  payments relating to selling or servicing efforts  and
(b) paying interest, carrying, or any other financing charges  on
any  unreimbursed  distribution or other expense  incurred  in  a
prior  fiscal year of the Series whether or not such charges  and
unreimbursed distribution or other expense are determined to be a
legal  obligation of each Series, in whole or  in  part,  by  the
Fund's Board of  Trustees.  The Fund's Board of  Trustees (in the
manner  contemplated in paragraph 11 of this Plan) shall  approve
the timing, categories and calculation of any payments under this
paragraph 3.

     4.1.  Each  Series will pay each person which has  acted  as
Distributor  of  Shares its Allocable Portion (as  such  term  is
defined in paragraphs 13.1 through 13.3) of the distribution fees
with  respect  to Shares of each Series in consideration  of  its
services as principal underwriter for the Shares of the Fund. The
distribution agreement pursuant to which a person acts  or  acted
as  principal  underwriter of the Shares is referred  to  as  the
"Applicable  Distribution Agreement." Such person shall  be  paid
its  Allocable  Portion of such distribution fees notwithstanding
such  person's  termination as Distributor of  the  Shares,  such
payments  to be changed or terminated only (i) as required  by  a
change in applicable law or a change in accounting policy adopted
by  the  Investment Companies Committee of the AICPA and approved
by FASB that results in a determination by the Fund's independent
accountants that any sales charges in respect of such Fund, which
are  not contingent deferred sales charges and which are not  yet
due  and  payable,  must  be accounted for  by  such  Fund  as  a
liability in accordance with GAAP, each after the effective  date
of  this Plan and restatement; (ii) if in the sole discretion  of
the  Board of  Trustees, after due consideration of such  factors
as   they   considered  relevant,  including   the   transactions
contemplated  in  any  purchase and sale agreement  entered  into
between  the  Fund's  Distributor and  any  commission  financing
entity,  the  Board  of   Trustees  determines  (in  the   manner
contemplated  in paragraph 12), in the exercise of its  fiduciary
duty,  that this Plan and the payments thereunder must be changed
or  terminated, notwithstanding the effect this action might have
on  the  Fund's  ability to offer and sell Shares;  or  (iii)  in
connection  with a Complete Termination of this  Plan,  it  being
understood that for this purpose a Complete Termination  of  this
Plan  occurs  only if this Plan is terminated and  the  Fund  has
discontinued the distribution of Shares or other back-end load or
substantially similar classes of shares; it being understood that
such  does  not include Class C shares, i.e., those sold  with  a
level load. The services rendered by a Distributor for which that
Distributor is entitled to receive its Allocable Portion  of  the
distribution  fee shall be deemed to have been completed  at  the
time  of  the initial purchase of the Shares (as defined  in  the
Applicable  Distribution  Agreement) (whether  of  that  Fund  or
another  fund) taken into account in computing that Distributor's
Allocable Portion of the distribution fee.

     4.2.  The  obligation of each Series to pay the distribution
fee  shall  terminate  upon  the  termination  of  this  Plan  in
accordance with the terms hereof.

     4.3.   The  right  of  a  Distributor  to  receive  payments
hereunder  may be transferred by that Distributor  (but  not  the
distribution  agreement itself or that Distributor's  obligations
thereunder)  in  order  to raise funds which  may  be  useful  or
necessary to perform its duties as principal underwriter, and any
such  transfer shall be effective upon written notice  from  that
Distributor  to the Fund. In connection with the foregoing,  each
Series  is authorized to pay all or part of the distribution  fee
and/or  contingent deferred sales charges with respect to  Shares
(upon the terms and conditions set forth in the then current Fund
prospectus)  directly  to such transferee  as  directed  by  that
Distributor.

     4.4.  As long as this Plan is in effect, the Fund shall  not
change  the  manner  in which the distribution  fee  is  computed
(except  as may be required by a change in applicable  law  or  a
change  in  accounting policy adopted by the Investment Companies
Committee  of  the AICPA and approved by FASB that results  in  a
determination  by  the  Fund's independent accountants  that  any
distribution  fees  which are not yet due and  payable,  must  be
accounted  for  by  such Fund as a liability in  accordance  with
GAAP).

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

     6.    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 Fund hereunder and shall provide
to  the Fund's Board of Trustees, and the Board of Trustees 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. Over the long-term the expenses  incurred
by  the  Distributor  for  engaging  directly  or  indirectly  in
financing  any activity which is primarily intended to result  in
the sale of Shares are likely to be greater then the distribution
fees receivable by the Distributor hereunder. Nevertheless, there
exists   the  possibility  that  for  a  short-term  period   the
Distributor may not have a sufficient amount of such expenses  to
warrant  reimbursement  by  receipt of  such  distribution  fees.
Although  the  Distributor undertakes not to make a profit  under
this  Plan, the Plan will be considered a compensation plan (i.e.
distribution  fees will be paid regardless of expenses  incurred)
in  order  to avoid the possibility of the Distributor not  being
able  to  receive such distribution fees because of  a  temporary
timing  difference between its incurring such  expenses  and  the
receipt of such distribution fees.

     7.   Neither this Plan nor any other transaction between the
Fund  and  the Distributor, or any successor or assignee thereof,
pursuant to this Plan shall be invalidated or in any way affected
by   the  fact  that  any  or  all  of  the  trustees,  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 trustees,  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.

     8.    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 or
any  of  its  shareholders,  creditors,   trustees  or  officers;
provided however, that nothing herein shall be deemed to  protect
the  Distributor against any liability to the Fund or the  Fund's
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.

     9.    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 Trustees  of
the  Fund,  including the vote of a majority of the trustees  who
are  not "interested persons" of the Fund and who have no  direct
or  indirect financial interest in the operation of 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.

     10.  This Plan may not be amended to increase materially the
amount  to be spent by the Fund 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 Trustees  of
the  Fund,  including the vote of a majority of the Trustees  who
are  not "interested persons" of the Fund and who have no  direct
or  indirect financial interest in the operation of 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.

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

     12.   This  Plan may be terminated at any time  without  the
payment  of  any  penalty by (a) the vote of a  majority  of  the
Trustees 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.  This  Plan
shall automatically terminate in the event of its assignment.

     13.1.      For  purposes  of  this Plan,  the  Distributor's
"Allocable Portion" of the distribution fee shall be 100% of such
distribution  fees  unless or until the  Fund  uses  a  principal
underwriter other than the Distributor. Thereafter the  Allocable
Portion shall be the portion of the distribution fee attributable
to (i) Shares of the Fund sold by the Distributor before there is
a  new principal underwriter, plus (ii) Shares of the Fund issued
in  connection with the exchange of Shares of another Fund in the
Lord,  Abbett  Family of Funds, plus (iii)  Shares  of  the  Fund
issued  in  connection  with the reinvestment  of  dividends  and
capital gains.

     13.2.       The  Distributor's  Allocable  Portion  of   the
distribution  fees  and  the contingent  deferred  sales  charges
arising  with  respect to Shares taken into account in  computing
the  Distributor's  Allocable  Portion  shall  be  limited  under
Article   III,  Sections  26(b)  and  (d)  or  other   applicable
regulations  of the NASD as if the Shares taken into  account  in
computing   the   Distributor's  Allocable   Portion   themselves
constituted a separate class of shares of the Fund.

     13.3.     The services rendered by the Distributor for which
the   Distributor  is  entitled  to  receive  the   Distributor's
Allocable  Portion of the distribution fees shall  be  deemed  to
have  been completed at the time of the initial purchase  of  the
Shares  (or shares of another Fund in the Lord Abbett  Family  of
Funds)   taken   into  account  in  computing  the  Distributor's
Allocable  Portion.   In  addition, the  Fund  will  pay  to  the
Distributor  any  contingent deferred sales  charges  imposed  on
redemption of Shares (upon the terms and conditions set forth  in
the then current Fund prospectus) taken into account in computing
the  Distributor's  Allocable Portion of the  distribution  fees.
Notwithstanding  anything  to the  contrary  in  this  Plan,  the
Distributor   shall  be  paid  its  Allocable  Portion   of   the
distribution fees regardless of the Distributor's termination  as
principal  underwriter  of  the  Shares  of  the  Fund,  or   any
termination  of  this Agreement other than in connection  with  a
Complete Termination (as defined in paragraph 4.1) of the Plan as
in effect on the date of execution of Distribution Agreement with
the  new Distributor. Except as provided in paragraph 4.1 and  in
the   preceding  sentence,  the  Fund's  obligation  to  pay  the
distribution  fees  to  the Distributor  shall  be  absolute  and
unconditional  and shall not be subject to any  dispute,  offset,
counterclaim  or  defense whatsoever (it  being  understood  that
nothing in this sentence shall be deemed a waiver by the Fund  of
its right separately to pursue any claims it may have against the
Distributor and to enforce such claims against any assets of  the
Distributor   (other   than  the  assets   represented   by   the
Distributor's  rights  to be paid its Allocable  Portion  of  the
distribution  fees and to be paid the contingent  deferred  sales
charges).

     14.   So  long  as  this Plan shall remain  in  effect,  the
selection and nomination of those  Trustees of the Fund  who  are
not  "interested  persons"  of the  Fund  are  committed  to  the
discretion  of such disinterested Trustees. 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.

           Rule 12b-1 Distribution Plan and Agreement
     Lord Abbett Investment Trust - Core Fixed Income Series
             -    Strategic Core Fixed Income Series
                                -
                    Class C Shares - Type II


          RULE 12b-1 DISTRIBUTION PLAN AND AGREEMENT dated as  of
March  15,  2000 by and between LORD ABBETT INVESTMENT  TRUST,  a
Delaware business trust (the "Fund"), on behalf of the Core Fixed
Income  Series  and Strategic Core Fixed Income  Series  (each  a
"Series"),  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 Class C shares of beneficial interest  (the
"Shares") pursuant to the Distribution Agreement between the Fund
and the Distributor, dated as of the date hereof, and

          WHEREAS, the Fund desires to adopt a Distribution  Plan
and Agreement (the "Plan") with the Distributor, as permitted  by
Rule  12b-1 under the Act, pursuant to which each Series 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 Trustees has  determined
that  there is a reasonable likelihood that the Plan will benefit
each Series 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 (or is reimbursed  for  by)  each
Series   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, each Series shall pay to the Distributor  fees
at each quarter-end after the sale of Shares (a) for services, at
an  annual rate not to exceed .25 of 1% of the average annual net
asset value of Shares outstanding and (b) for distribution, at an
annual  rate  not to exceed .75 of 1% of the average  annual  net
asset  value of Shares outstanding.  For purposes of the  payment
of  the fees above, (A) Shares issued pursuant to an exchange for
Class  C  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  above have been outstanding and (B) payments  will  be
based  on  Shares  outstanding during any such  quarter.   Shares
outstanding above include Shares issued for reinvested  dividends
and  distributions.  The Board of Trustees of the Fund shall from
time  to time determine the amounts, within the foregoing maximum
amounts,  that  each  Series may pay the  Distributor  hereunder.
Such  determinations by the Board of Trustees 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 Conduct 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
Fund  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.    The  Distributor  may  use  amounts  received  as
distribution  fees  hereunder from each  Series  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.   The  Fund's
Board of Trustees (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 Declaration and Agreement of  Trust
of  the Fund.  If the Distributor waives all or a portion of fees
which  are  to be paid by each Series hereunder, the  Distributor
shall  not  be  deemed  to  have waived  its  rights  under  this
Agreement to have each Series 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 each Series  hereunder
and  shall provide to the Fund's Board of Trustees, and the Board
of Trustees 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 trustees, 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
trustees, 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.

          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, each Series or any of its shareholders, creditors, trustees
or  officers;  provided  however, that nothing  herein  shall  be
deemed  to protect the Distributor against any liability  to  the
Fund   or   each  Series'  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
Trustees  of  the Fund, including the vote of a majority  of  the
trustees  who  are not "interested persons" of the Fund  and  who
have no direct or indirect financial interest in the operation of
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  each  Series  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 Trustees of the Fund, including the vote  of  a
majority of the trustees who are not "interested persons" of  the
Fund and who have no direct or indirect financial interest in the
operation of 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 Trustees of
the  Fund,  including the vote of a majority of the trustees  who
are  not "interested persons" of the Fund and who have no  direct
or  indirect financial interest in the operation of this Plan  or
in  any agreement related to this Plan.  The Board of Trustees 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
trustees 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.   This  Plan
shall automatically terminate in the event of its assignment.

          12.   So long as this Plan shall remain in effect,  the
selection  and nomination of those trustees of the Fund  who  are
not  "interested  persons"  of the  Fund  are  committed  to  the
discretion of such disinterested trustees.  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.

          RULE 12b-1 DISTRIBUTION PLAN AND AGREEMENT dated as  of
March  15, 2000, by and between LORD ABBETT INVESTMENT  TRUST,  a
Delaware business trust (the "Fund"), on behalf of the Core Fixed
Income  Series  and Strategic Core Fixed Income  Series  (each  a
"Series"),  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
Series'   Class  P  shares  (the  "Shares")  pursuant    to   the
Distribution  Agreement  between the Fund  and  the  Distributor,
dated as of the date hereof, and

          WHEREAS, the Fund desires to adopt a Distribution  Plan
and  Agreement (the "Plan") for each Series with the Distributor,
as  permitted by Rule 12b-1 under the Act, pursuant to which each
Series  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 Trustees has  determined
that  there is a reasonable likelihood that the Plan will benefit
each Series 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 each Series 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, each Series shall pay to the Distributor  fees
at  each quarter-end (a) for services, at an annual rate  not  to
exceed .20% 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 .25 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 clauses  (a)  and
(b)  above  include  Shares issued for reinvested  dividends  and
distributions that have been outstanding for the quarter or more.

                The Board of Trustees 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  each  Series  may   pay   the
Distributor  hereunder.   Such determinations  by  the  Board  of
Trustees  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
Conduct  Rules  of  the  NASD Regulation, 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) each
Series  shall not pay with respect to any Authorized  Institution
service fees equal to more than .20% 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  each  Series to finance  any  activity  that  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  Trustees 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 Trustees  (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 Declaration and Agreement of  Trust
of  the Fund.  If the Distributor waives all or a portion of fees
which  are  to be paid by each Series hereunder, the  Distributor
shall  not  be  deemed  to  have waived  its  rights  under  this
Agreement to have the Fund 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 each Series  hereunder
and  shall provide to the Fund's Board of Trustees, and the Board
of Trustees 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 trustees, 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
trustees, 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.

          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, each Series or any of the shareholders, creditors, trustees
or  officers  of the Fund; provided however, that nothing  herein
shall  be deemed to protect the Distributor against any liability
to  the  Fund or each Series' 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
Trustees  of  the Fund, including the vote of a majority  of  the

          9.     This   Plan  may  not  be  amended  to  increase

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 Trustees of
the  Fund,  including the vote of a majority of the trustees  who
are  not "interested persons" of the Fund and who have no  direct
or  indirect financial interest in the operation of this Plan  or
in  any agreement related to this Plan. The Board of Trustees  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
trustees of the Fund who are not "interested persons" of the Fund
and  have  no  trustees  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 trustees of the Fund  who  are
not  "interested  persons"  of the  Fund  are  committed  to  the
discretion of such disinterested trustees.  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.

instrument  to be executed in its name and on its behalf  by  its

Amended and Restated Plans as of March 9, 2000
Pursuant to Rule 18f3(d)
under the Investment Company Act of 1940
(As adopted August 15, 1996)


     Rule 18f3 (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  noninterested  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,  Class B,  Class C, Class Y, and Class P
(Pension Class) shares as indicated for each Fund on Schedule A attached hereto.
Shares of Lord Abbett Series Fund,  Inc. shall be divided into Class P and Class
VC (Variable Contract Class).

2.    SALES CHARGES AND DISTRIBUTION AND SERVICE FEES.

     (a) Initial Sales Charge. Class A shares will be traditional frontend sales
charge  shares,  offered at their net asset value ("NAV") plus a sales charge in
the case of each Fund,  except for such categories of purchasers who qualify for
Class A share purchases  without a front-end sales charge,  as described in such
Fund's  prospectus  and/or  statement of additional  information as from time to
time in effect.

     Class B shares,  Class C shares,  Class Y shares,  Variable  Contract Class
shares and P 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, and Class P 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 12b1 under the 1940 Act (each, a "12b1 Plan").

     Pursuant to a 12b1 Plan with respect to the Class A shares,  if  effective,
each Fund will  generally  pay (i) at the time such  shares are sold,  a onetime
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, to retirement plans with 100
or more eligible  employees,  as described in the Fund's prospectus as from time
to time in effect,  or with  respect to  purchases  made by certain  401(k) plan
multi-fund  platforms  which have been authorized by the Board to receive the 1%
distribution  fee on net new sales,  (ii) a  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 12b1 Plan by a vote of the Board, including
a majority of the  independent  directors or trustees  thereof,  up to an annual
rate of 0.25% of the  average  daily NAV of the Class A  shares.  The  effective
dates  of  certain  of the  12b1  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 12b1  Plan  with  respect  to the  Class B  shares  that are
outstanding for less than 8 years, 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 fees and .75% in distribution
fees).

     Pursuant to a 12b1 Plan with respect to the Class C shares,  if  effective,
each Fund will generally pay a onetime service and  distribution fee at the time
such  shares  are sold of up to 1% of their NAV  (excluding  shares  issued  for
reinvested  dividends  and  distributions)  and a  continuing  annual  fee (paid
quarterly), 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). The Distributor
may retain up to .10% of the payments  referred to in this paragraph  related to
fixed-income funds to compensate it for its services rendered in connection with
the distribution of Class C shares, including the payment of commissions.

     Pursuant  to a Type  II  Class  C  share  12b-1  Plan,  if  effective,  the
Distributor  will make  payments at the time of sale of up to 1% of the value of
the shares  purchased at the time of sale. Each Fund shall pay the  Distributor,
on a quarterly  basis,  up to .25% and .75% for service and  distribution  fees,
respectively,  of the  average  annual net asset  value of  outstanding  shares,
including reinvested dividend or distribution shares.

     Pursuant  to a 12b-1  Plan with  respect  to Class P  shares,  the Board is
authorized  to approve  annual fee payments from Class P assets of up to .75% of
the average  annual NAV of such assets  consisting  of service and  distribution
fees,  at maximum  annual  rates not  exceeding  .25% for  service  and .50% for
distribution. The Board has approved an annual service fee payable quarterly, of
 .20% and .25% for service and distribution  fees,  respectively,  of the average
annual net asset value of outstanding shares.

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

     The Variable  Contract  Class shares' Rule 12b-1 Plan was terminated by the
Board on March 17, 1999.

     (c) Contingent Deferred Sales Charges ("CDSC"). Subject to some exceptions,
Class A shares subject to the onetime sales  distribution  fee of up to 1% under
the Rule 12b1 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 twentyfourth 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.

     The Class Y, the Variable Contract Class and the Class P shares will not be
subject to a CDSC.

3.    ClassSpecific  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 9647, on a classspecific
basis:  (a) fees under a 12b1 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  shareholders  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 taxreturn 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,  Blue Sky  expenses  will be
treated as common 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  and
statement of additional  information  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  Abbettsponsored  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 multipleclass 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.
