                                                          Core Fixed Income Fund
                                                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.  Each Fund expects 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 a portfolio turnover rate substantially in excess of 100%.
     For the fiscal year ended  November 30, 1999,  the portfolio  turnover rate
     for each Fund was 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 ("Strate gic 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's reinvestment options may carry 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.  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.

(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
--------------------------------------------------------------------------------

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

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

Class A shares                             $570                       $772
--------------------------------------------------------------------------------
Class B shares                             $166                       $514
--------------------------------------------------------------------------------

Class P shares                             $110                       $343
--------------------------------------------------------------------------------

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

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, Class C and Class P shares,  although
     there may be a contingent  deferred  sales  charge  ("CDSC") on Class B and
     Class C shares 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.

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 Company.

     date of purchase.  For example,  the  anniversaries for shares purchased on
     May 1 will be May 1 of each succeeding year.

     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).

<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.

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

<PAGE>


     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  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, as well as
     the tax  consequences of gains or losses from the redemption or exchange of
     your shares.


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  underflying  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  concession 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  Series  Fund;  (3) Lord

<PAGE>

     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:

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.

(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 one 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 than 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.

Lord  Abbett  Investment  Trust  (the  "Company")  was  organized  as a Delaware
business trust on August 16, 1993.  The Company has six funds,  two of which are
discussed in this  Statement of  Additional  Information:  the Core Fixed Income
Series  ("Core Fixed Income  Fund") and the  Strategic  Core Fixed Income Series
("Strategic  Core  Fixed  Income  Fund")  (each  a  "Fund").   These  Funds  are
diversified  open-end  investment  management  companies  registered  under  the
Investment  Company  Act of 1940,  as amended  (the  "Act").  Each Fund has five
classes of shares (A, B, C, P, and Y), but only four classes of shares (A, B, C,
and P) are offered by this  Statement of  Additional  Information.  The Board of
Trustees will allocate authorized shares of capital stock among the classes from
time to time. All shares have equal noncumulative voting rights and equal rights
with  respect  to  dividends,   assets  and  liquidation,   except  for  certain
class-specific  expenses.  They are fully paid and nonassessable when issued and
have no preemptive or conversion  rights,  except as described in this Statement
of Additional Information.  Further classes or funds may be added in the future.
The Act requires  that where more than one class or fund  exists,  each class or
fund must be  preferred  over all other  classes  or funds in  respect of assets
specifically allocated to such class or fund.


                                       1.
                               Investment Policies

Fundamental  Investment  Restrictions.  Each Fund is  subject  to the  following
investment  restrictions,  which  cannot be changed  without  the  approval of a
majority of its outstanding shares.

Each Fund may not:

     (1)  borrow  money  (except  that (i) each Fund may  borrow  from banks (as
          defined  in the  Act) in  amounts  up to 33 1/3% of its  total  assets
          (including  the amount  borrowed),  (ii) each Fund may borrow up to an
          additional 5% of its total assets for temporary  purposes,  (iii) each
          Fund may obtain such  short-term  credit as may be  necessary  for the
          clearance of purchases and sales of portfolio securities and (iv) each
          Fund may  purchase  securities  on margin to the extent  permitted  by
          applicable law);

     (2)  pledge its assets  (other  than to secure  such  borrowings  or to the
          extent  permitted by each Fund's  investment  policies as permitted by
          applicable law);

     (3)  engage in the underwriting of securities,  except pursuant to a merger
          or  acquisition  or  to  the  extent  that,  in  connection  with  the
          disposition  of its  portfolio  securities,  it may be deemed to be an
          underwriter under federal securities laws;

     (4)  make loans to other  persons,  except that the  acquisition  of bonds,
          debentures  or other  corporate  debt  securities  and  investment  in
          government obligations,  commercial paper,  pass-through  instruments,
          certificates of deposit, bankers acceptances, repurchase agreements or
          any similar  instruments shall not be subject to this limitation,  and
          except  further  that  each  Fund may lend its  portfolio  securities,
          provided that the lending of portfolio  securities may be made only in
          accordance with applicable law;

     (5)  buy or  sell  real  estate  (except  that  each  Fund  may  invest  in
          securities  directly or indirectly secured by real estate or interests
          therein  or  issued  by  companies  which  invest  in real  estate  or
          interests therein),  commodities or commodity contracts (except to the
          extent  each  Fund may do so in  accordance  with  applicable  law and
          without registering - as a commodity pool operator under the Commodity
          Exchange Act as, for example, with futures contracts);

     (6)  with respect to 75% of the gross assets,  buy securities of one issuer
          representing  more  than (i) 5% of the  Fund's  gross  assets,  except
          securities issued or guaranteed by the U.S.  Government,  its agencies
          or  instrumentalities  or (ii) 10% of the  voting  securities  of such
          issuer;

     (7)  invest  more than 25% of its  assets,  taken at market  value,  in the
          securities  of  issuers  in any  particular  industry  (excluding  (i)
          securities of the U.S. Government,  its agencies and instrumentalities
          and (ii) mortgage-backed securities); and

     (8)  issue senior  securities  to the extent such  issuance  would  violate
          applicable law.

Compliance  with the investment  restrictions in this Section will be determined
at the time of purchase or sale of the portfolio investment.

Non-Fundamental  Investment  Restrictions.  In addition  to the  policies in the
Prospectus and the investment restrictions above which cannot be changed without
shareholder approval, each Fund is also subject to the following non-fundamental
investment  policies  which  may be  changed  by the Board of  Trustees  without
shareholder approval.

Each Fund may not:

     (1)  borrow in excess  of 5% of its  gross  assets  taken at cost or market
          value, whichever is lower at the time of borrowing, and then only as a
          temporary measure for extraordinary or emergency purposes;

     (2)  make short sales of securities or maintain a short position  except to
          the extent permitted by applicable law;

     (3)  invest  knowingly  more  than  15% of its net  assets  (at the time of
          investment) in illiquid securities,  except for securities  qualifying
          for resale under Rule 144A of the  Securities Act of 1933 deemed to be
          liquid by the Board of Trustees;

     (4)  invest  in  securities  of  other  investment  companies,   except  as
          permitted by applicable law;

     (5)  hold  securities  of any issuer if more than 1/2 of 1% of the issuer's
          securities  are  owned  beneficially  by one  or  more  of the  Fund's
          officers or  directors  or by one or more  partners or members of each
          Fund's  underwriter  or  investment  adviser  if these  owners  in the
          aggregate  own  beneficially  more than 5% of the  securities  of such
          issuer;

     (6)  invest in warrants if, at the time of  acquisition,  its investment in
          warrants,  valued at the lower of cost or market,  would  exceed 5% of
          each Fund's total assets (included within such limitation,  but not to
          exceed 2% of the  Fund's  total  assets,  are  warrants  which are not
          listed on the New York or American  Stock  Exchange or a major foreign
          exchange);

     (7)  invest in real estate  limited  partnership  interests or interests in
          oil,  gas or other  mineral  leases,  or  exploration  or  development
          programs,  except  that each Fund may invest in  securities  issued by
          companies  that engage in oil,  gas or other  mineral  exploration  or
          development activities;

     (8)  write,   purchase  or  sell  puts,   calls,   straddles,   spreads  or
          combinations  thereof,  except to the extent  permitted  in the Fund's
          Prospectus  and  Statement of Additional  Information,  as they may be
          amended from time to time; or

     (9)  buy from or sell to any of the Fund's officers, directors,  employees,
          or each Fund's investment  adviser or any of the investment  adviser's
          officers,  directors, partners or employees, any securities other than
          shares of beneficial interest in the Fund.

Although  there is no  current  intention  to do so,  each  Fund may  invest  in
financial futures and options on financial futures.

As discussed  above,  each Fund may purchase  securities on a when-issued  basis
with  settlement  taking place after the purchase date (without  amortizing  any
premiums).  If the  Funds  use this  investment  technique,  it is  expected  to
contribute  significantly to the portfolio turnover rates. However, it will have
little or no transaction  cost or adverse tax  consequences.  Transaction  costs
normally  will  exclude  brokerage  because each Fund's  fixed-income  portfolio
transactions  are usually on a principal basis and any markups charged  normally
will be more than offset by the beneficial economic consequences  anticipated at
the time of purchase or no purchase will be made.  Generally,  short-term losses
on  short-term  U.S.  government  securities  purchased  under  this  investment
technique  tend to  offset  any  short-term  gains  due to such  high  portfolio
turnover.

INVESTMENT TECHNIQUES

Each  Fund  intends  to use,  from time to time,  one or more of the  investment
techniques  described below.  While some of these  techniques  involve risk when
used independently,  each Fund intends to use them to reduce risk and volatility
in its portfolio.

Foreign  Currency Hedging  Techniques.  Strategic Core Fixed Income Fund may use
various foreign currency hedging techniques  described below,  including forward
foreign currency contracts and foreign currency put and call options.

Forward Foreign Currency Contracts. A forward foreign currency contract involves
an obligation to purchase or sell a specific amount of a specific  currency at a
set price at a future  date.  Strategic  Core Fixed Income Fund expects to enter
into forward foreign currency contracts in primarily two  circumstances.  First,
when the fund  enters  into a contract  for the  purchase  or sale of a security
denominated in a foreign  currency,  it may desire to "lock in" the U.S.  dollar
price of the security.  By entering into a forward  contract for the purchase or
sale of the amount of  foreign  currency  involved  in the  underlying  security
transaction,  the fund will be able to protect against a possible loss resulting
from an  adverse  change in the  relationship  between  the U.S.  dollar and the
subject  foreign  currency  during the period  between the date the  security is
purchased or sold and the date on which payment is made or received.

Second,  when  management  believes  that the currency of a  particular  foreign
country may suffer a decline against the U.S. dollar,  the Fund may enter into a
forward contract to sell the amount of foreign currency  approximating the value
of some or all of the fund's  portfolio  securities  denominated in such foreign
currency  or, in the  alternative,  the fund may use a  cross-hedging  technique
whereby it sells another currency which the fund expects to decline in a similar
way but which has a lower  transaction  cost.  Precise  matching  of the forward
contract  amount and the value of the securities  involved will not generally be
possible  since the  future  value of such  securities  denominated  in  foreign
currencies  will change as a  consequence  of market  movements  in the value of
those  securities  between the date the forward contract is entered into and the
date it matures.  The fund does not intend to enter into such forward  contracts
under this second circumstance on a continuous basis.

Foreign  Currency  Put and Call  Options.  The Fund  may also  purchase  foreign
currency put options and write foreign  currency call options on U.S.  exchanges
or U.S. over-the-counter markets. A put option gives the fund, upon payment of a
premium, the right to sell a currency at the exercise price until the expiration
of the option and serves to insure against  adverse  currency price movements in
the underlying portfolio assets denominated in that currency.

                                       4

Exchange-listed  options  markets in the United  States  include  several  major
currencies,  and trading may be thin and illiquid.  A number of major investment
firms  trade  unlisted  options  which are more  flexible  than  exchange-listed
options  with  respect  to strike  price and  maturity  date.  Unlisted  options
generally are available in a wider range of currencies,  including those of most
of the developed countries. Unlisted foreign currency options are generally less
liquid than listed  options  and  involve  the credit risk  associated  with the
individual  issuer.  Unlisted options are subject to a limit of 5% of the fund's
net assets.

A call  option  written  by the fund  gives the  purchaser,  upon  payment  of a
premium,  the right to purchase  from the fund a currency at the exercise  price
until  the  expiration  of the  option.  The Fund may  write a call  option on a
foreign  currency  only in  conjunction  with a purchase of a put option on that
currency.  Such a strategy is  designed to reduce the cost of downside  currency
protection by limiting currency appreciation  potential.  The face value of such
writing may not exceed 90% of the value of the  securities  denominated  in such
currency  invested in by the fund or in such cross currency  (referred to above)
to cover such call writing.

Lending  Portfolio  Securities.  Each  Fund may  lend  portfolio  securities  to
registered brokers-dealers. These loans, if and when made, may not exceed 30% of
the Fund's total assets.  The Funds' loans of securities will be  collateralized
by cash or marketable  securities issued or guaranteed by the U.S. Government or
its agencies ("U.S.  Government  securities") or other  permissible  means in an
amount at least equal to the market value of the loaned securities. From time to
time,  each Fund may pay a part of the  interest  received  with  respect to the
investment  of  collateral  to the  borrower  and/or a third  party  that is not
affiliated  with the fund and is acting as a  "placing  broker."  No fee will be
paid to affiliated persons of a fund .

By  lending  portfolio  securities,  each Fund may can  increase  its  income by
continuing  to  receive  income on the  loaned  securities  as well as by either
investing  the  cash  collateral  in  permissible  investments,   such  as  U.S.
government  securities,  or obtaining  yield in the form of interest paid by the
borrower  when  such  U.S.  government  securities  or other  forms of  non-cash
collateral  are used as  security.  Each Fund  will  comply  with the  following
conditions whenever it loans securities: (i) the Fund must receive at least 100%
collateral  from the borrower;  (ii) the borrower  must increase the  collateral
whenever the market value of the securities  loaned rises above the level of the
collateral;  (iii) the Fund must be able to terminate the loan at any time; (iv)
the Fund must receive reasonable  compensation with respect to the loan, as well
as any dividends,  interest or other distributions on the loaned securities; (v)
the Fund may pay only  reasonable  fees in  connection  with the loan;  and (vi)
voting rights on the loaned  securities may pass to the borrower except that, if
the Fund has knowledge of a material event adversely affecting the investment in
the loaned securities,  the Fund must terminate the loan and regain the right to
vote the securities.

Repurchase  Agreements.  Each Fund may enter  into  repurchase  agreements  with
respect to a security. A repurchase agreement is a transaction by which the Fund
acquires a security and  simultaneously  commits to resell that  security to the
seller (a bank or securities dealer),  and the seller commits to repurchase that
security,  at an agreed  upon  price on an agreed  upon date.  The resale  price
reflects the purchase price plus an agreed upon market rate of interest which is
unrelated to the coupon rate or date of maturity of the purchased security.  (In
this type of transaction,  the securities  purchased by a Fund must have a total
value in excess of the value of the repurchase agreement.) Each Fund requires at
all  times  that the  repurchase  agreement  be  collateralized  by cash or U.S.
government securities having a value equal to, or in excess of, the value of the
repurchase  agreement.  Such  agreements  permit  the Funds to keep all of their
assets at work while retaining flexibility in pursuit of investments of a longer
term nature.

The use of repurchase  agreements  involves certain risks.  For example,  if the
seller  of the  agreement  defaults  on its  obligation  to  provide  additional
collateral or to repurchase the  underlying  securities at a time when the value
of these  securities has declined,  a Fund may incur a loss upon  disposition of
them.  If  the  seller  of  the  agreement  becomes  insolvent  and  subject  to
liquidation  or  reorganization  under  the  Bankruptcy  Code or other  laws,  a
bankruptcy court may determine that the underlying securities are collateral not
within the control of the Fund and are therefore  subject to sale by the trustee
in  bankruptcy.  Even though the repurchase  agreements  may have  maturities of
seven days or less, they may lack liquidity, especially if the issuer encounters
financial  difficulties.  While  management  acknowledges  these  risks,  it  is
expected that they can be controlled  through stringent  selection  criteria and
careful monitoring procedures. Management intends to limit repurchase agreements
for the funds to transactions with dealers and financial  institutions  believed
to present minimal credit risks. Management will monitor creditworthiness of the
repurchase agreement sellers on an ongoing basis.

                                       5

<PAGE>

Each Fund  will  enter  into  repurchase  agreements  only  with  those  primary
reporting  dealers that report to the Federal  Reserve Bank of New York and with
the 100 largest United States  commercial  banks and the  underlying  securities
purchased under the agreements will consist only of those  securities in which a
fund otherwise may invest.

When-Issued  Transactions.  As stated in the Prospectus,  each Fund may purchase
portfolio securities on a when-issued basis.  When-issued transactions involve a
commitment  by  a  Fund  to  purchase  securities,  with  payment  and  delivery
("settlement")  to  take  place  in the  future,  in  order  to  secure  what is
considered to be an advantageous price or yield at the time of entering into the
transaction.  The value of fixed-income securities to be delivered in the future
will  fluctuate as interest rates vary.  During the period between  purchase and
settlement,  the value of the securities will fluctuate and assets consisting of
cash  and/or  marketable   securities   (normally   short-term  U.S.  government
securities)  marked to market daily in an amount  sufficient  to make payment at
settlement  will  be  segregated  at our  custodian  in  order  to pay  for  the
commitment.  There is a risk that market yields  available at settlement  may be
higher  than  yields  obtained  on the  purchase  date,  which  could  result in
depreciation of value of fixed-income when-issued securities. At the time a Fund
makes the  commitment  to purchase a security on a  when-issued  basis,  it will
record the  transaction and reflect the liability for the purchase and the value
of the security in determining its net asset value.  Each Fund generally has the
ability to close out a purchase  obligation  on or before  the  settlement  date
rather than take delivery of the security. Under no circumstance will settlement
for such securities take place more than 120 days after the purchase date.

Average  Duration.  Each Fund will  maintain a duration  within two years of the
bond market's duration as measured by the Lehman Aggregate Bond Index. Currently
this index has a duration of approximately five years.

Some of the securities in each Fund's portfolio may have periodic  interest rate
adjustments  based  upon an index such as the 91-day  Treasury  Bill rate.  This
periodic  interest  rate  adjustment  tends  to  lessen  the  volatility  of the
security's  price.  With respect to securities  with an interest rate adjustment
period of one year or less,  each Fund will, when  determining  average-weighted
duration, treat such a security's maturity as the amount of time remaining until
the next interest rate adjustment.

Instruments such as GNMA, FNMA, FHLMC securities and similar  securities  backed
by amortizing  loans  generally  have shorter  effective  maturities  than their
stated maturities.  This is due to changes in amortization caused by demographic
and economic forces such as interest rate movements.  These effective maturities
are calculated based upon historical payment patterns and therefore have shorter
duration than would be implied by their stated final  maturity.  For purposes of
determining each Fund's average maturity, the maturities of such securities will
be  calculated   based  upon  the  issuing   agency's   payment   factors  using
industry-accepted valuation models.

1.   Outside  directors'/trustees' fees, including attendance fees for board and
     committee  meetings,  are allocated among all Lord  Abbett-sponsored  funds
     based on the net assets of each Fund.  A portion of the fee  payable by the
     Fund  to its  outside  directors/trustees  may  be  deferred  under  a plan
     ("equity  based  plan") that deems the  deferred  amounts to be invested in
     shares of the Fund for later  distribution to the  directors/trustees.  The
     amounts of the aggregate  compensation payable by the Company in accordance
     with the equity-based  plan as of November 30, 1999 deemed invested in Fund
     shares,  including  dividends  reinvested  and  changes in net asset  value
     applicable to such deemed investments were: Mr. Bigelow,  $9, Mr. Bush, $0,
     Mr. Calhoun,  $9, Mr. Dixon, $0, Mr. Jansing,  $9, Mr.  MacDonald,  $0, Mr.
     Millican,  $9, and Mr.  Neff,  $9. If the amounts  deemed  invested in Fund
     shares were added to each  director's  actual holdings of Fund shares as of
     November 30, 1999,  each would own, the  following:  Mr.  Bigelow,  $9, Mr.
     Bush, $9, Mr. Calhoun,  $9, Mr. Dixon, $0, Mr. Jansing,  $9, Mr. MacDonald,
     $0, Mr. Millican, $9, and Mr. Neff, $9.

2.   The amounts in Column 3 were accrued by the Lord Abbett-sponsored funds for
     the twelve months ended October 31, 1999.

3.   This column shows  aggregate  compensation,  including  directors/trustees'
     fees and  attendance  fees for board and  committee  meetings,  of a nature
     referred to in footnote one, paid by the Lord Abbett-sponsored funds during
     the year ended December 31, 1999, including fees  directors/trustees'  have
     chosen to defer but does not include amounts accrued under the equity-based
     plan and shown in Column 3.

4.   The equity-based plans superseded a previously approved retirement plan for
     all directors/trustees.  Directors/trustees had the option to convert their
     accrued  benefits  under the retirement  plan.  All of the current  outside
     directors/trustees  except one made such  election.  Mr.  Jansing  chose to
     continue to receive  benefits under the retirement plan which provides that
     outside  directors/trustees may receive annual retirement benefits for life
     equal to their final annual retainer  following  retirement at or after age
     72 with at least ten years of service.  Thus, if Mr. Jansing were to retire
     and the annual retainer  payable by the Funds were the same as it is today,
     he would receive annual retirement benefits of $50,000.


Except where indicated,  the following  executive officers of the Fund have been
associated with Lord Abbett for over five years. Messrs. Brown, Carper,  Gerber,
Hilstad,  Hudson,  Morris, and Towle are partners of Lord Abbett; the others are
employees. None have received compensation from the Funds.

                                       4.
                             Portfolio Transactions

Each  Fund's   policy  is  to  obtain  best   execution  on  all  our  portfolio
transactions,  which means that each Fund seeks to have  purchases  and sales of
portfolio  securities  executed at the most favorable  prices,  considering  all
costs of the  transaction  including  brokerage  commissions (if any) and dealer
markups and markdowns and any brokerage  commissions and taking into account the
full range and quality of the brokers' services.  Consistent with obtaining best
execution,  we generally pay, as described below, a higher  commission than some
brokers might charge on the same  transaction.  This policy with respect to best
execution  governs the  selection  of brokers or dealers and the market in which
the  transaction  is  executed.  To the  extent  permitted  by law,  we may,  if
considered  advantageous,   make  a  purchase  from  or  sale  to  another  Lord
Abbett-sponsored fund without the intervention of any broker-dealer.

Broker-dealers  are selected on the basis of their  professional  capability and
the value and quality of their brokerage and research  services.  Normally,  the
selection is made by traders who are officers of each Lord Abbett-sponsored fund
and also are employees of Lord Abbett.  These traders do the trading as well for
other  accounts -- investment  companies  (of which they are also  officers) and
other  investment  clients -- managed by Lord Abbett.  They are  responsible for
obtaining best execution.

We may pay a brokerage  commission  on the  purchase or sale of a security  that
could  be  purchased  from or  sold to a  market  maker  if our net  cost of the
purchase or the net  proceeds to us of the sale are at least as  favorable as we
could obtain on a direct purchase or sale.  Brokers who receive such commissions
may also  provide  research  services  at least some of which are useful to Lord
Abbett  in their  overall  responsibilities  with  respect  to us and the  other
accounts they manage.  Research includes trading equipment and computer software
packages, acquired from third-party suppliers, that enable Lord Abbett to access
various information bases and may include the furnishing of analyses and reports
concerning  issuers,  industries,   securities,  economic  factors  and  trends,
portfolio strategy and the performance of accounts. Such services may be used by
Lord Abbett in servicing all their  accounts,  and not all of such services will
necessarily  be used by Lord Abbett in connection  with their  management of the
fund; conversely,  such services furnished in connection with brokerage on other
accounts  managed by Lord Abbett may be used in connection with their management
of the  fund,  and not all of such  services  will  necessarily  be used by Lord
Abbett in connection  with their advisory  services to such other  accounts.  We
have been advised by Lord Abbett that  research  services  received from brokers
cannot be allocated to any  particular  account,  are not a substitute  for Lord
Abbett's  services but are  supplemental  to their own research effort and, when
utilized,  are subject to internal  analysis  before being  incorporated by Lord
Abbett into their investment  process.  As a practical  matter,  it would not be
possible for Lord Abbett to generate all of the information  presently  provided
by brokers.  While  receipt of research  services from  brokerage  firms has not
reduced Lord Abbett's  normal research  activities,  the expenses of Lord Abbett
could be  materially  increased  if it  attempted  to generate  such  additional
information  through its own staff and  purchased  such  equipment  and software
packages directly from the suppliers.

No commitments  are made  regarding the  allocation of brokerage  business to or
among brokers, and trades are executed only when they are dictated by investment
decisions  of the Lord  Abbett-sponsored  funds to  purchase  or sell  portfolio
securities.

If two or more  broker-dealers are considered capable of offering the equivalent
likelihood  of  best  execution,   the  broker-dealer  who  has  sold  the  Lord
Abbett-sponsored  funds'  shares  and/or  shares of other Lord  Abbett-sponsored
funds may be preferred.  When, in the opinion of the investment adviser,  two or
more broker (either directly or through their correspondent clearing agents) are
in a position to obtain the best  execution,  preference may be given to brokers
who  have  sold  shares  of a Fund or who  have  provided  investment  research,
statistical, or other related services to the investment adviser.

                                       10

<PAGE>

If other  clients of Lord Abbett buy or sell the same  security at the same time
as  a  Lord  Abbett-sponsored  fund  does,  transactions  will,  to  the  extent
practicable,  be allocated among all participating accounts in proportion to the
amount  of each  order  and will be  executed  daily  until  filled so that each
account shares the average price and commission  cost of each day. Other clients
who direct that their brokerage  business be placed with specific brokers or who
invest  through wrap accounts  introduced to Lord Abbett by certain  brokers may
not  participate  with us in the buying and  selling of the same  securities  as
described  above.  If these  clients wish to buy or sell the same  security as a
Lord  Abbett-sponsored  fund does, they may have their transactions  executed at
times different from our transactions and thus may not receive the same price or
incur the same commission cost as Lord Abbett-sponsored fund does.


                                       5.
                             Purchases, Redemptions
                            and Shareholder Services

Information  concerning  how we value our shares for the purchase and redemption
of  our  shares  is  described  in  the   Prospectus   under   "Purchases"   and
"Redemptions", respectively.

As disclosed in the Prospectus, we calculate our net asset value as of the close
of the New York Stock  Exchange  ("NYSE")  on each day that the NYSE is open for
trading by dividing our total net assets by the number of shares  outstanding at
the time of  calculation.  The NYSE is closed on  Saturdays  and Sundays and the
following  holidays:  New Year's Day,  Martin Luther King, Jr. Day,  Presidents'
Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,  Thanksgiving and
Christmas.

The Fund values its portfolio  securities at market value as of the close of the
NYSE. Market value will be determined as follows:  securities listed or admitted
to trading  privileges  on the New York or  American  Stock  Exchange  or on the
NASDAQ National  Market System are valued at the last sales price,  or, if there
is no sale on that day, at the mean between the last bid and asked  prices,  or,
in the case of bonds, in the over-the-counter  market if, in the judgment of the
Fund's  officers,  that market more accurately  reflects the market value of the
bonds.  Over-the-counter  securities  not traded on the NASDAQ  National  Market
System are valued at the mean between the last bid and asked prices.  Securities
for which market  quotations  are not  available are valued at fair market value
under procedures approved by the Board of Trustees.

For each class of shares,  the net asset value per share will be  determined  by
taking the net assets and dividing by the number of shares outstanding.


The Fund has entered into a distribution  agreement with Lord Abbett Distributor
under which Lord Abbett Distributor is obligated to use its best efforts to find
purchasers for the shares of the Funds,  and to make reasonable  efforts to sell
Fund shares so long as, in Lord Abbett  Distributor's  judgment,  a  substantial
distribution can be obtained by reasonable efforts.


Conversion  of Class B Shares.  The  conversion  of Class B shares on the eighth
anniversary  of their purchase is subject to the  continuing  availability  of a
private letter ruling from the Internal Revenue Service or an opinion of counsel
to the  effect  that the  conversion  of Class B shares  does not  constitute  a
taxable  event for the holder  under  Federal  income tax law. If such 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.  Although Class B shares could
then be exchanged for Class A shares on the basis of relative net asset value of
the two classes,  without the imposition of a sales charge or fee, such exchange
could constitute a taxable event for the holder.

ALTERNATIVE SALES ARRANGEMENTS

Classes of  Shares.  Each Fund  offers  share  classes  (Class A, B, C, or P) as
described  in  the  Prospectus.   The  different  classes  of  shares  represent
investments  in the same  portfolio of  securities  but are subject to different
expenses and will likely have different share prices. Investors should read this
section carefully to determine which class represents the best investment option
for their particular situation.



                                       11
<PAGE>

Class A Shares.  If you buy Class A shares,  you pay an initial  sales charge on
investments  of less than $1 million (or on investments  for  employer-sponsored
retirement  plans under the Internal  Revenue Code  (hereinafter  referred to as
"Retirement Plans") with less than 100 eligible employees or on investments that
do not  qualify to be under a "special  retirement  wrap  program"  as 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
wrap fee program). If you purchase Class A shares as part of an investment of at
least $1 million (or for Retirement  Plans with at least 100 eligible  employees
or under a  special  retirement  wrap  program)  in  shares  of one or more Lord
Abbett-sponsored  funds,  you will not pay an initial sales  charge,  but if you
redeem  any of those  shares  within 24 months  after the month in which you buy
them, you may pay to the Fund a contingent  deferred sales charge ("CDSC") of 1%
except for redemptions under a special  retirement wrap program.  Class A shares
are subject to service and  distribution  fees that are  currently  estimated to
total annually The initial sales charge rates,  the CDSC and the Rule 12b-1 plan
applicable to the Class A shares are described below.

Class B Shares.  If you buy Class B shares,  you pay no sales charge at the time
of  purchase,  but if you redeem your  shares  before the sixth  anniversary  of
buying them, you will normally pay a CDSC to Lord Abbett Distributor.  That CDSC
varies  depending  on how long you own  shares.  Class B shares  are  subject to
service  and  distribution  fees at an annual rate of 1% of the annual net asset
value of the Class B shares.  The CDSC and the Rule 12b-1 plan applicable to the
Class B shares are described below.

Class C Shares.  If you buy Class C shares,  you pay no sales charge at the time
of  purchase,  but if you redeem your  shares  before the first  anniversary  of
buying  them,  you will  normally  pay the Fund a CDSC of 1%. Class C shares are
subject to service and  distribution  fees at an annual rate of 1% of the annual
net  asset  value of the  Class C  shares.  The CDSC  and the  Rule  12b-1  plan
applicable to the C shares are described below.

Class P Shares.  If you buy Class P shares,  you pay no sales charge at the time
of purchase,  and if you redeem your shares you pay no CDSC.  Class P shares are
subject to service and  distribution  fees at an annual rate of .45 of 1% of the
average  daily  net  asset  value of the Class P  shares.  The Rule  12b-1  plan
applicable  to the Class P shares is  described  in "Class P Rule  12b-1  Plan".
Class P shares are available to a limited number of investors.

Which  Class of Shares  Should You  Choose?  Once you decide that the Fund is an
appropriate  investment  for you,  the  decision  as to which class of shares is
better  suited to your needs  depends  on a number of  factors  which you should
discuss with your financial adviser. The Fund's class-specific  expenses and the
effect of the different  types of sales charges on your  investment  will affect
your investment  results over time. The most important  factors are how much you
plan to invest and how long you plan to hold your investment.  If your goals and
objectives  change over time and you plan to  purchase  additional  shares,  you
should  re-evaluate those factors to see if you should consider another class of
shares.

In the following discussion, to help provide you and your financial adviser with
a framework in which to choose a class,  we have made some  assumptions  using a
hypothetical  investment in a Fund. We used the sales charge rates that apply to
Class  A,  Class  B and  Class  C,  and  considered  the  effect  of the  higher
distribution  fees on Class B and  Class C  expenses  (which  will  affect  your
investment  return). Of course, the actual performance of your investment cannot
be predicted and will vary,  based on a Fund's actual  investment  returns,  the
operating  expenses  borne by each class of shares,  and the class of shares you
purchase.  The factors briefly discussed below are not intended to be investment
advice,  guidelines  or  recommendations,   because  each  investor's  financial
considerations are different. The discussion below of the factors to consider in
purchasing a particular  class of shares assumes that you will purchase only one
class of shares and not a combination of shares of different classes.

How Long Do You Expect to Hold Your  Investment?  While future  financial  needs
cannot be  predicted  with  certainty,  knowing how long you expect to hold your
investment  will assist you in selecting the  appropriate  class of shares.  For
example,  over time, the reduced sales charges available for larger purchases of
Class A shares may offset the effect of paying an initial  sales  charge on your
investment,  compared to the effect over time of higher class-specific  expenses
on Class B or Class C shares for which no initial sales charge is paid.  Because
of the effect of  class-based  expenses,  your choice  should also depend on how
much you plan to invest.

Investing for the Short Term. If you have a short-term  investment horizon (that
is,  you plan to hold your  shares  for not more  than six  years),  you  should
probably  consider  purchasing  Class A or Class C shares  rather  than  Class B
shares.  This is because of the effect of the Class B CDSC if you redeem  before
the sixth  anniversary  of your  purchase,  as well as the effect of the Class B
distribution  fee on the  investment  return for that  class in the short  term.
Class C shares might be the  appropriate  choice  (especially for investments of
less than $100,000), because there is no initial sales charge on Class C shares,
and the CDSC does not apply to amounts you redeem after holding them one year.

                                       12
<PAGE>

However,  if you plan to invest more than $100,000 for the short term,  then the
more you invest and the more your investment horizon increases toward six years,
the more  attractive  the Class A share  option may become.  This is because the
annual  distribution  fee on Class C shares  will have a greater  impact on your
account over the longer term than the reduced  front-end sales charge  available
for  larger  purchases  of Class A shares.  For  example,  Class A might be more
appropriate  than Class C for  investments of more than $100,000  expected to be
held for 5 or 6 years (or more).  For investments  over $250,000  expected to be
held 4 to 6 years (or more),  Class A shares may become  more  appropriate  than
Class  C. If you are  investing  $500,000  or  more,  Class  A may  become  more
desirable as your investment horizon approaches 3 years or more.

For most investors who invest $1 million or more or for Retirement Plans with at
least 100 eligible employees or for investments pursuant to a special retirement
wrap program, in most cases Class A shares will be the most advantageous choice,
no matter how long you intend to hold your shares.  For that reason,  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. In addition,
it may not be  suitable  for you to place an order for Class B or C shares for a
Retirement Plan with at least 100 eligible employees or for a special retirement
wrap program. You should discuss this with your financial advisor.

Investing  for the Longer Term.  If you are  investing  for the longer term (for
example,  to provide  for future  college  expenses  for your  child) and do not
expect to need access to your money for seven years or more,  Class B shares may
be an appropriate  investment  option, if you plan to invest less than $100,000.
If you plan to invest more than $100,000 over the long term, Class A shares will
likely be more  advantageous than Class B shares or Class C shares, as discussed
above,  because of the effect of the expected  lower expenses for Class A shares
and the reduced initial sales charges available for larger  investments in Class
A shares under the Fund's Rights of Accumulation.

Of course,  these examples are based on  approximations of the effect of current
sales charges and expenses on a  hypothetical  investment  over time, and should
not be relied on as rigid guidelines.


Are There  Differences  in Account  Features  That Matter to You?  Some  account
features  are  available  in whole or in part to  Class A,  Class B and  Class C
shareholders.  Other features (such as Systematic Withdrawal Plans) might not be
advisable in non-Retirement  Plan accounts for Class B shareholders  (because of
the effect of the CDSC on the entire  amount of a  withdrawal  if it exceeds 12%
annually) and in any account for Class C  shareholders  during the first year of
share  ownership  (due  to the  CDSC  on  withdrawals  during  that  year).  See
"Systematic  Withdrawal  Plan"  under  "Services  For  Fund  Investors"  in  the
Prospectus  for more  information  about the 12% annual waiver of the CDSC.  You
should  carefully  review  how you plan to use your  investment  account  before
deciding  which class of shares you buy. For example,  the dividends  payable to
Class B and Class C shareholders will be reduced by the expenses borne solely by
each of these classes,  such as the higher distribution fee to which Class B and
Class C shares are subject, as described below.


How Does It Affect Payments to My Broker?  A salesperson,  such as a broker,  or
any other person who is entitled to receive compensation for selling Fund shares
may  receive  different  compensation  for  selling  one class than for  selling
another class. As discussed in more detail below, such compensation is primarily
paid at the time of sale in the case of  Class A and B shares  and is paid  over
time, so long as shares remain outstanding, in the case of Class C shares. It is
important that investors understand that the primary purpose of the CDSC for the
Class B shares  and the  distribution  fee for Class B and Class C shares is the
same as the purpose of the front-end sales charge on sales of Class A shares: to
compensate  brokers and other persons selling such shares. The CDSC, if payable,
supplements  the Class B  distribution  fee and reduces the Class C distribution
fee expenses for the Fund and Class C shareholders.

Rule  12b-1  Plans.  As  described  in the  Prospectus,  the Fund has  adopted a
Distribution Plan and Agreement on behalf of each Fund pursuant to Rule 12b-1 of
the Act for each  class of such  Fund:  the "A  Plan",  the "B Plan"  and the "C
Plan", respectively. In adopting each Plan and in approving its continuance, the
Board of has concluded that there is a reasonable likelihood that each Plan will
benefit  its  respective  Class and such  Classes'  shareholders.  The  expected
benefits  include  greater sales and lower  redemptions of shares,  which should
allow each Class to maintain a  consistent  cash flow,  and a higher  quality of
service to shareholders by authorized  institutions  than would otherwise be the
case.  Lord  Abbett  used all  amounts  received  under the A, B and C Plans for
payments to dealers for (i) providing  continuous  services to the shareholders,
such as answering  shareholder  inquiries,  maintaining  records,  and assisting
shareholders  in  making  redemptions,   transfers,   additional  purchases  and
exchanges and (ii) their assistance in distributing shares of each Fund.

                                       13
<PAGE>

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

Contingent  Deferred Sales Charges. A Contingent Deferred Sales Charge ("CDSC"),
applies  regardless of class,  and (i) will be assessed on the lesser of the net
asset value of the shares at the time of  redemption  or the  original  purchase
price and (ii) is not imposed on the amount of your account value represented by
the  increase  in net asset  value over the initial  purchase  price  (including
increases due to the reinvestment of dividends and capital gains distributions).

Class A Shares. As stated in the Prospectus,  subject to certain  exceptions,  a
CDSC of 1% is imposed with respect to those Class A shares (or Class A shares of
another Lord  Abbett-sponsored  fund or fund acquired  through  exchange of such
shares)  on which a fund has paid the  one-time  distribution  fee of 1% if such
shares are  redeemed out of the Lord  Abbett-sponsored  family of funds within a
period  of 24  months  from  the end of the  month in which  the  original  sale
occurred.

Class B Shares. As stated in the Prospectus,  subject to certain exceptions,  if
Class B shares of the Fund (or Class B shares of another  Lord  Abbett-sponsored
fund or fund acquired  through  exchange of such shares) are redeemed out of the
Lord  Abbett-sponsored  Family of Funds for cash before the sixth anniversary of
their purchase, a CDSC will be deducted from the redemption proceeds.  The Class
B CDSC is paid to Lord Abbett Distributor to reimburse its expenses, in whole or
in part,  of providing  distribution-related  service to the Fund in  connection
with the sale of Class B shares.

To determine  whether the CDSC applies to a redemption,  the Funds redeem shares
in the following  order:  (1) shares  acquired by  reinvestment of dividends and
capital gains  distributions,  (2) shares held on or after the sixth anniversary
of  their  purchase,   and  (3)  shares  held  the  longest  before  such  sixth
anniversary.

The amount of the contingent  deferred sales charge will depend on the number of
years since you invested and the dollar amount being redeemed,  according to the
following schedule:

</TABLE>

In the table, an  "anniversary" is the same calendar day in each respective year
after the date of purchase.  For example, the anniversaries for shares purchased
on May 1 of each succeeding year. All purchases are considered to have been made
on the business day on which the purchase order was accepted.

Class C Shares. As stated in the Prospectus,  subject to certain exceptions,  if
Class C shares  are  redeemed  for cash  before the first  anniversary  of their
purchase,  the  redeeming  shareholder  will be  required  to pay to the Fund on
behalf of Class C shares a CDSC of 1% of the lower of cost or the then net asset
value of Class C shares  redeemed.  If such shares are  exchanged  into the same
class of another Lord Abbett-sponsored fund and subsequently redeemed before the
first  anniversary of their original  purchase,  the charge will be collected by
the other fund on behalf of the Fund's Class C shares.

General.  Each percentage (1% in the case of Class A and C shares and 5% through
1% in the case of Class B shares) used to calculate  CDSCs  described  above for
the Class A, Class B and Class C shares is sometimes  hereinafter referred to as
the "Applicable Percentage".

                                       14
<PAGE>

With respect to Class A and Class B shares, no CDSC is payable on redemptions by
participants or beneficiaries from employer-sponsored retirement plans under the
Internal  Revenue  Code  for  benefit  payments  due  to  plan  loans,  hardship
withdrawals,  death,  retirement or  separation  from service and for returns of
excess  contributions  to retirement  plan sponsors.  In the case of Class A and
Class C shares,  the CDSC is received by the applicable  fund and is intended to
reimburse  all or a portion  of the  amount  paid by the fund if the  shares are
redeemed  before  the fund has had an  opportunity  to realize  the  anticipated
benefits of having a long-term  shareholder  account in the fund. In the case of
Class B shares,  the CDSC is received by Lord Abbett Distributor and is intended
to reimburse its expenses of providing  distribution-related service to the Fund
(including  recoupment of the commission  payments made) in connection  with the
sale of Class B shares before Lord Abbett  Distributor has had an opportunity to
realize its  anticipated  reimbursement  by having such a long-term  shareholder
account subject to the B Plan distribution fee.

The other funds which  participate in the Telephone  Exchange  Privilege (except
(a) Lord Abbett U.S.  Government  Securities Money Market Fund, Inc.  ("GSMMF"),
(b) certain funds and Lord Abbett  Tax-Free  Income Trust for which a Rule 12b-1
Plan is not yet in effect, and (c) any authorized institution's affiliated money
market fund satisfying Lord Abbett Distributor as to certain omnibus account and
other criteria,  hereinafter referred to as an "authorized money market fund" or
"AMMF"  (collectively,  the "Non-12b-1  Funds")) have instituted a CDSC for each
class on the same terms and  conditions.  No CDSC will be charged on an exchange
of shares of the same class  between Lord Abbett Funds or between such Funds and
AMMF. Upon redemption of shares out of the Lord Abbett family of Funds or out of
AMMF,  the CDSC will be charged on behalf of and paid:  (i) to the Fund in which
the original purchase  (subject to a CDSC) occurred,  in the case of the Class A
and Class C shares and (ii) to Lord Abbett  Distributor if the original purchase
was subject to a CDSC,  in the case of the Class B shares.  Thus, if shares of a
Lord Abbett Fund are exchanged for shares of the same class of another such Fund
and the shares of the same class tendered  ("Exchanged Shares") are subject to a
CDSC,  the CDSC will carry over to the shares of the same class being  acquired,
including GSMMF and AMMF ("Acquired  Shares").  Any CDSC that is carried over to
Acquired  Shares is calculated as if the holder of the Acquired  Shares had held
those shares from the date on which he or she became the holder of the Exchanged
Shares.  Although the Non-12b-1  Funds will not pay a distribution  fee on their
own shares, and will, therefore,  not impose their own CDSC, the Non-12b-1 Funds
will collect the CDSC (a) on behalf of other Lord Abbett  Funds,  in the case of
the Class A and Class C shares and (b) on behalf of Lord Abbett Distributor,  in
the case of the Class B shares. Acquired Shares held in GSMMF and AMMF which are
subject to a CDSC will be  credited  with the time such shares are held in GSMMF
but will not be credited with the time such shares are held in AMMF.  Therefore,
if your Acquired Shares held in AMMF qualified for no CDSC or a lower Applicable
Percentage at the time of exchange into AMMF,  that  Applicable  Percentage will
apply to  redemptions  for cash from AMMF,  regardless of the time you have held
Acquired Shares in AMMF.

In no event will the amount of the CDSC exceed the Applicable  Percentage of the
lesser of: (i) the net asset value of the shares  redeemed or (ii) the  original
cost of such  shares (or of the  Exchanged  Shares for which  such  shares  were
acquired). No CDSC will be imposed when the investor redeems (i) amounts derived
from  increases in the value of the account above the total cost of shares being
redeemed due to increases in net asset value,  (ii) shares with respect to which
no Lord Abbett Fund or Fund paid a 12b-1 fee and, in the case of Class B shares,
Lord Abbett  Distributor  paid no sales charge or service fee (including  shares
acquired   through   reinvestment   of  dividend   income  and   capital   gains
distributions) or (iii) shares which,  together with Exchanged Shares, have been
held  continuously for 24 months from the end of the month in which the original
sale  occurred  (in the case of Class A  shares);  for six years or more (in the
case of Class B shares) or for one year or more (in the case of Class C shares).
In  determining  whether a CDSC is  payable,  (a) shares not subject to the CDSC
will be redeemed before shares subject to the CDSC and (b) of the shares subject
to a CDSC, those held the longest will be the first to be redeemed.


Exchanges.  The Prospectus briefly describes the Telephone  Exchange  Privilege.
You may exchange  some or all of your shares for those of the same class of: (i)
Lord Abbett-sponsored  funds currently offered to the public with a sales charge
(front-end,  back-end or level),  (ii) GSMMF or (iii) AMMF, to the extent offers
and sales may be made in your state. You should read the prospectus of the other
Funds before  exchanging.  In establishing a new account by exchange,  shares of
the Fund being exchanged must have a value equal to at least the minimum initial
investment required for the Fund into which the exchange is made.


Shareholders in other Lord  Abbett-sponsored  funds and AMMF have the same right
to exchange their shares for the Fund's shares.  Exchanges are based on relative
net asset values on the day instructions are received by the Fund in Kansas City
if the  instructions are received prior to the close of the NYSE in proper form.
No sales  charges are imposed  except in the case of  exchanges  out of GSMMF or
AMMF  (unless a sales  charge  (front-end,  back-end  or level)  was paid on the
initial  investment).  Exercise of the exchange  privilege  will be treated as a
sale for federal income tax purposes,  and,  depending on the  circumstances,  a
gain or loss may be  recognized.  In the case of an exchange of shares that have
been held for 90 days or less where no sales charge is payable on the  exchange,
the original sales charge incurred with respect to the exchanged  shares will be
taken  into  account in  determining  gain or loss on the  exchange  only to the
extent such charge  exceeds the sales charge that would have been payable on the
acquired  shares had they been  acquired for cash rather than by  exchange.  The
portion of the original sales charge not so taken into account will increase the
basis of the acquired shares.

                                       15
<PAGE>

Shareholders have the exchange  privilege unless they refuse it in writing.  You
should  not view the  exchange  privilege  as a means for  taking  advantage  of
short-term swings in the market,  and we reserve the right to terminate or limit
the privilege of any shareholder who makes frequent exchanges.  We can revoke or
modify the privilege for all shareholders upon 60 days' prior notice.  "Eligible
Funds" are AMMF and other Lord Abbett-sponsored Funds which are eligible for the
exchange  privilege,  except Lord Abbett Series Fund  ("LASF")  which offers its
shares only in connection with certain variable annuity contracts.


Letter of Intention.  Under the terms of the Letter of Intention as described in
the Prospectus to invest $100,000 or more over a 13-month period as described in
the Prospectus, shares of Lord Abbett-sponsored funds (other than shares of LASF
and GSMMF,  unless holdings in GSMMF are attributable to shares exchanged from a
Lord  Abbett-sponsored  fund offered  with a front-end,  back-end or level sales
charge)  currently  owned by you are  credited as  purchases  (at their  current
offering  prices on the date the Letter is signed)  toward  achieving the stated
investment and reduced initial charges for Class A shares. Class A shares valued
at 5% of the amount of intended  purchases  are  escrowed and may be redeemed to
cover the additional  sales charge  payable if the Letter is not completed.  The
Letter of  Intention is neither a binding  obligation  on you to buy, nor on the
Fund to sell, the full amount indicated.

Rights of Accumulation.  As stated in the Prospectus,  purchasers (as defined in
the Prospectus) may accumulate their investment in Lord  Abbett-sponsored  funds
(other than LASF and GSMMF,  unless holdings in GSMMF are attributable to shares
exchanged from a Lord Abbett-sponsored  Fund offered with a front-end,  back-end
or level  sales  charge)  so that a  current  investment,  plus the  purchaser's
holdings  valued at the current maximum  offering price,  reach a level eligible
for a discounted sales charge for Class A shares.


Net Asset Value Purchases of Class A Shares.  As stated in the  Prospectus,  our
Class A shares may be purchased at net asset value by our  directors,  employees
of Lord Abbett,  employees of our  shareholder  servicing agent and employees of
any securities  dealer having a sales agreement with Lord Abbett who consents to
such   purchases  or  by  the  trustee  or   custodian   under  any  pension  or
profit-sharing plan or Payroll Deduction IRA established for the benefit of such
persons  or for the  benefit  of  employees  of any  national  securities  trade
organization  to which Lord Abbett  belongs or any company with an account(s) in
excess of $10  million  managed  by Lord  Abbett  on a  private-advisory-account
basis.  For purposes of this  paragraph,  the terms  "directors" and "employees"
include a director's or employee's  spouse  (including the surviving spouse of a
deceased  director or employee).  The terms " directors"  and "employees of Lord
Abbett" also include other family members and retired directors and employees.


Our Class A shares also may be purchased at net asset value (a) at $1 million or
more,  (b) with dividends and  distributions  from Class A shares and other Lord
Abbett-sponsored  funds, except for LASF, (c) under the loan feature of the Lord
Abbett-sponsored  prototype  403(b) plan for share  purchases  representing  the
repayment of principal and interest, (d) by certain authorized brokers, dealers,
registered investment advisers or other financial  institutions who have entered
into an  agreement  with Lord Abbett  Distributor  in  accordance  with  certain
standards approved by Lord Abbett  Distributor,  providing  specifically for the
use of our shares in particular  investment products made available for a fee to
clients of such  brokers,  dealers,  registered  investment  advisers  and other
financial   institutions,   and  (e)  by  employees,   partners  and  owners  of
unaffiliated consultants and advisors to Lord Abbett, Lord Abbett Distributor or
Lord Abbett-sponsored funds who consent to such purchase if such persons provide
service to Lord Abbett,  Lord Abbett  Distributor  or such funds on a continuing
basis and are familiar  with such funds,  (f) through  Retirement  Plans with at
least 100 eligible  employees,  (g) in connection with a merger,  acquisition or
other  reorganization,  and (h)  through a  "special  retirement  wrap  program"
sponsored  by an  authorized  institution  showing  one or more  characteristics
distinguishing  it, in the opinion of Lord Abbett Distributor from a mutual fund
advisory 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 Class A 12b-1 Plan and the fact that the program relates
to a participant-directed Retirement Plan. Shares are offered at net asset value
to these  investors  for the purpose of promoting  goodwill  with  employees and
others  with  whom  Lord  Abbett   Distributor  and/or  the  fund  has  business
relationships.


Our shares may be issued at net asset value in exchange for the assets,  subject
to possible  tax  adjustment,  of a personal  holding  company or an  investment
company.  There are economies of selling efforts and sales-related expenses with
respect to offers to these investors and those referred to above.

                                       16

Redemptions.  A  redemption  order is in proper form when it contains all of the
information and  documentation  required by the order form or  supplementally by
Lord Abbett Distributor or the Fund to carry out the order. The signature(s) and
any legal capacity of the signer(s) must be guaranteed by an Eligible Guarantor,
which is any broker or bank that is a member of the medallion stamp program. See
the Prospectus for expedited redemption procedures.


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

Our Board of  Trustees  may  authorize  redemption  of all of the  shares in any
account  in which  there are  fewer  than 25  shares.  Before  authorizing  such
redemption, the Board must determine that it is in our economic best interest or
necessary  to  reduce   disproportionately   burdensome  expenses  in  servicing
shareholder  accounts.  At least 30 days'  prior  written  notice  will be given
before any such redemption,  during which time shareholders may avoid redemption
by bringing their accounts up to the minimum set by the Board.

Div-Move. Under the Div-Move service described in the Prospectus, you can invest
the  dividends  paid on your  account  into an  existing  account  in any  other
Eligible Fund. The account must be either your account,  a joint account for you
and your spouse,  a single account for your spouse,  or a custodial  account for
your minor  child  under the age of 21. You should  read the  prospectus  of the
other fund before investing.

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

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

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

                                   Performance

The Fund computes the average  annual  compounded  rate of total return for each
class during specified  periods that would equate the initial amount invested to
the ending  redeemable  value of such  investment  by adding one to the computed
average  annual total return,  raising the sum to a power equal to the number of
years  covered by the  computation  and  multiplying  the result by one thousand
dollars which  represents a hypothetical  initial  investment.  The  calculation
assumes  deduction  of the  maximum  sales  charge  (as  described  in the  next
paragraph) from the amount invested and reinvestment of all income dividends and
capital gains  distributions on the reinvestment  dates at prices  calculated as
stated in the Prospectus.  The ending redeemable value is determined by assuming
a complete  redemption  at the end of the period  covered by the average  annual
total return computation.

In  calculating  total  returns for Class A shares,  the current  maximum  sales
charge of 5.75% (as a  percentage  of the offering  price) is deducted  from the
initial  investment (unless the return is shown at net asset value). For Class B
shares,  the payment of the applicable CDSC (5.0% prior to the first anniversary
of purchase, 4.0% prior to the second anniversary of purchase, 3.0% prior to the
third and fourth anniversaries of purchase,  2.0% prior to the fifth anniversary
of purchase,  1.0% prior to the sixth anniversary of purchase and no CDSC on and
after the sixth  anniversary  of purchase)  is applied to the Fund's  investment
result for that class for the time  period  shown  (unless  the total  return is
shown at net asset  value).  For Class C shares,  the 1.0% CDSC is  applied to a
Fund's  investment  result for that class for the time period shown prior to the
first  anniversary  of purchase  (unless the total  return is shown at net asset
value).  Total  returns  also  assume  that  all  dividends  and  capital  gains
distributions during the period are reinvested at net asset value per share, and
that the investment is redeemed at the end of the period.

Yield  quotation for each Class is based on a 30-day period ended on a specified
date, computed by dividing our net investment income per share earned during the
period by the maximum  offering price per share of such Class on the last day of
the period.  This is  determined  by finding the  following  quotient:  take the
Class'  dividends  and  interest  earned  during the period  minus its  expenses
accrued for the period and divide by the product of (i) the average daily number
of shares of such Class  outstanding  during the period  that were  entitled  to
receive dividends and (ii) the maximum offering price per share of such Class on
the last day of the period.  To this quotient add one. This sum is multiplied by
itself  five  times.   Then  one  is   subtracted   from  the  product  of  this
multiplication  and the remainder is  multiplied  by two.  Yield for the Class A
shares reflects the deduction of the maximum initial sales charge,  but may also
be shown based on a Fund's net asset  value per share.  Yields for Class B and C
shares do not reflect the deduction of the CDSC.


                                       7.
                                      Taxes


Each Fund  intends to elect and to qualify for special  tax  treatment  afforded
regulated  investment  companies  under the  Internal  Revenue Code of 1986 (the
"Code").  If it so  qualifies,  each  Fund  (but not its  shareholders)  will be
relieved  of  federal  income  taxes on the  amount  it  timely  distributes  to
shareholders.  If in any  taxable  year a Fund does not  qualify as a  regulated
investment  company,  all of its  taxable  income  will be  taxed to the Fund at
regular corporate rates.

Each Fund  contemplates  declaring  as  dividends  substantially  all of its net
investment  income.  Dividends  paid by a Fund from its  investment  income  and
distributions out of short-term capital gains are taxable to its shareholders as
ordinary  income  from  dividends,  whether  received in cash or  reinvested  in
additional  shares of a Fund.  Distributions  paid by a Fund of its net realized
long-term  capital  gains are taxable to  shareholders  as capital  gains,  also
whether  received  in cash or  reinvested  in  shares.  Each  Fund will send its
shareholders  annual  information  concerning the tax treatment of dividends and
other distributions.

Upon a sale,  exchange or  redemption  of shares of a Fund, a  shareholder  will
recognize  short-  or  long-term  capital  gain  or  loss,  depending  upon  the
shareholder's  holding period in the Fund's shares.  However, if a shareholder's
holding  period in his shares is six month or less,  any capital  loss  realized
from a sale or exchange of such shares must be treated as long-term capital loss
to the extent of dividends classified as "capital gains dividends" received with
respect to such shares.  The maximum tax rates  applicable  to net capital gains
recognized by individuals and other non-corporate  taxpayers are (i) the same as
ordinary  income rates for capital assets held for one year or less and (ii) 20%
for  capital  assets  held  for more  than one  year.  Capital  gains or  losses
recognized by corporate  shareholders  are subject to tax at the ordinary income
tax rates applicable to corporations.

                                       18
<PAGE>

Losses on the sale of shares are not deductible if, within a period beginning 30
days  before the date of the sale and ending 30 days after the date of the sale,
the taxpayer acquires shares that are substantially identical.

Some  shareholders  may  be  subject  to a 31%  withholding  tax  on  reportable
dividends,   capital  gains   distributions  and  redemption  payments  ("backup
withholding").  Generally,  shareholders  subject to backup  withholding will be
those for whom a certified taxpayer  identification number is not on file with a
Fund or who, to a Fund's  knowledge,  have furnished an incorrect  number.  When
establishing  an account,  an investor must certify  under  penalties of perjury
that such  number is  correct  and that he or she is not  otherwise  subject  to
backup withholding.

The writing of call options and other investment  techniques and practices which
each Fund may utilize may affect the character and timing of the  recognition of
gains and  losses.  Such  transactions  may  increase  the amount of  short-term
capital  gain  realized  by a Fund,  which  is  taxed as  ordinary  income  when
distributed to shareholders.

Each Fund may be subject to foreign  withholding  taxes,  which would reduce the
yield on its investments.  It is generally expected that a Fund's  shareholders,
who are subject to United  States  federal  income tax,  will not be entitled to
claim a federal  income tax credit or deduction for foreign income taxes paid by
the Fund.

Each Fund will be subject to a 4%  non-deductible  excise tax on certain amounts
not  distributed  or treated as having been  distributed  on a timely basis each
calendar  year.  Each Fund intends to  distribute to  shareholders  each year an
amount adequate to avoid the imposition of such excise tax.

Gain and loss realized by each Fund on certain transactions,  including sales of
foreign debt securities and certain  transactions  involving  foreign  currency,
will be treated as ordinary  income or loss for federal  income tax  purposes to
the  extent,  if any,  that  such gain or loss is  attributable  to  changes  in
exchange rates for foreign  currencies.  Accordingly,  distributions  taxable as
ordinary  income will include the net amount,  if any, of such foreign  exchange
gain and will be reduced by the net  amount,  if any, of such  foreign  exchange
loss.

If a Fund  purchases  shares  in  certain  foreign  investment  entities  called
"passive foreign investment companies," the Fund may be subject to United States
federal  income tax on a portion of any "excess  distribution"  or gain from the
disposition  of such  shares,  even if such income is  distributed  as a taxable
dividend by the Fund to its  shareholders.  Additional  charges in the nature of
interest may be imposed on each Fund in respect of deferred  taxes  arising from
such  distributions  or gains.  If each Fund were to make a "qualified  electing
fund"  election with respect to its investment in a passive  foreign  investment
company,  in lieu of the  foregoing  requirements,  a Fund might be  required to
include in income each year a portion of the  ordinary  earnings and net capital
gains of the qualified  electing fund,  even if such amount were not distributed
to the  Fund.  Alternatively,  if each  Fund  were  to  make a  "mark-to-market"
election with respect to its investment in a passive foreign investment company,
gain or loss with respect to the investment would be considered  realized at the
end of  each  taxable  year  of a Fund  even if a Fund  continued  to  hold  the
investment, and would be treated as ordinary income or loss to the Fund.

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

Except as discussed in the Prospectus,  the receipt of dividends from a Fund may
be  subject  to tax under  laws of state or local tax  authorities.  You  should
consult your tax adviser on state and local tax matters.

                           Information About the Funds



Rule 18f-2 under the Act provides that any matter  required to be submitted,  by
the provisions of the Act or applicable  state law or otherwise,  to the holders
of the  outstanding  voting  securities  of an  investment  company  such as the
Company shall not be deemed to have been effectively  acted upon unless approved
by the  holders of a majority  of the  outstanding  shares of each class or fund
affected by such matter.  Rule 18f-2 further provides that a class or fund shall
be deemed to be affected by a matter  unless the interests of each class or fund
in the  matter are  substantially  identical  or the matter  does not affect any
interest of such class or fund.

The Company  does not hold annual  meetings of  shareholders  unless one or more
matters are  required to be acted on by  shareholders  under the Act.  Under the
Company's  Declaration of Trust,  shareholder meetings may be called at any time
by certain  officers of the Company or by a majority of the Trustees (i) for the
purpose of taking action upon any matter  requiring the vote or authority of the
Company's shareholders or upon other matters deemed to be necessary or desirable
or (ii) upon the written  request of the holders of a least  one-quarter  of the
shares of the Company's outstanding shares and entitled to vote at the meeting.


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