We recognize each investor's need for a  well-diversified  portfolio.  Our value
investing  process can benefit investors in both large and small company stocks.
Our goal, to provide  investors  competitive  returns with  relatively  moderate
fluctuations in price, applies to both Series.

The  last  six  months  saw a  dramatic  swing in  investors'  attitudes  toward
corporate  earnings  and fair market  value in the stock  market.  At the end of
1999,  investors were caught up in what could only be deemed a "momentum market"
-- where  investors  seemed to hastily and  recklessly buy stocks simply because
their  prices were on the rise.  The turn of the  millennium  brought  with it a
broadening out in the stock market,  as investors sought new  opportunities  and
turned their attention to small- and mid-sized companies.  However,  they seemed
to remain  focused on  growth-oriented  technology  stocks that provided  recent
strong  returns and pay little mind to the rapidly  rising  valuations  of these
stocks in  relation to their  underlying  fundamentals.  Throughout  most of the
first quarter,  growth stocks (as measured by the Russell 2000 Growth  Index(2))
outperformed value stocks (as measured by the Russell 2000 Value Index(3)),  and
a climate of high economic growth, strong corporate earnings and higher interest
rates created extreme volatility in the U.S. equities market.  Feeling confident
amid this strong macroeconomic environment, investors defiantly ignored a series
of Federal  Reserve ("the Fed") rate  increases and continued to pour money into
the stock market. In late March, the tides turned and value-oriented stocks made
a sharp rebound as investors  shifted  their focus away from highly  speculative
earnings growth and toward stronger company fundamentals. The ensuing months saw
a day-to-day volley between growth and value stocks, as confused investors tried
to move their money into what they hoped would be the next surging area.

About the Large-Cap Series(4)
Throughout the period,  our relatively  large exposure to energy  companies paid
off well as rising oil prices  helped  boost the price of many of these  stocks.
Select stocks of pharmaceutical  companies and HMOs also enjoyed strong rallies,
and several of our consumer  staple  holdings  added a boost late in the period.
Additionally,  we  benefited  from  the  outperformance  of many of our  utility
company stocks.  Early in the period,  the select  technology  company stocks we
held  continued  to be  positive  contributors  to the  portfolio.  However,  we
aggressively  pared back our  overall  exposure to  technology  in late March in
response to high valuations and hints of negative  fundamentals  seen in some of
our stocks.  Many of the proceeds from these sales went towards  investments  in
areas  where we saw more  intrinsic  value,  such as  stocks of  capital  goods,
healthcare and, to a lesser extent,  less  credit-sensitive  financial  services
companies. Stocks of financial services companies underperformed for the period,
but since  investors  had already  discounted  the  prospect of several Fed rate
increases, they fared better than they typically have during periods of interest
rate anxiety.

                                                                               1

REPORT TO SHAREHOLDERS

We were hardest hit by our remaining  technology exposure late in the period, as
well as our exposure to companies  in sectors  such as  communication  services,
basic materials (metals and chemicals) and retail. In many cases, we had already
begun to scale back our holdings in these  companies  when their stocks began to
decline.

About the Small-Cap Value Series(4)

Strong global growth and rising oil prices created  excellent  opportunities for
our  holdings in oil services and energy  companies.  Additionally,  our careful
stock  selection in the materials and  processing,  transportation  and producer
durables  sectors  was  the  biggest  contributor  to the  portfolio's  positive
performance.  The consumer  discretionary  sector was an area where we uncovered
what we believed were some  "diamonds in the rough."  Improved  valuations  have
helped  boost a number of our holdings in this  sector,  and a renewed  focus on
education  spending by presidential  candidates has aided our holdings in stocks
of education-oriented companies. We added a few investments in financial company
stocks that we felt had an  advantage  over others in the  industry.  But on the
whole, we grossly underweighted this sector -- which had underperformed for most
of the period -- compared to leading  indicators of small-cap value  performance
such as the Russell 2000 Value Index.

We were very pleased  with the strong  performance  that some of the  technology
company  stocks in the portfolio  exhibited  early in the period.  However,  our
overweighting in technology,  and in particular  information services companies,
hurt us later on as investors  sought safety in sectors that displayed  stronger
business  fundamentals  and more  visible  earnings  growth  relative to company
valuations.  Transportation  stocks performed well for us early in the year, but
suffered later on. Likewise,  a shift in consumer spending had a negative effect
on selected retail and apparel holdings.

Looking Ahead

While investors attempt to hit moving targets in this volatile market, we remain
true to our long-term, value-driven investment approach. Our research is focused
on individual companies.  However, certain sectors may be overweighted from time
to time  primarily  because  we have  identified  numerous  companies  in  those
industries that we believe represent  outstanding value. In the months ahead, we
will pay special  attention to the Fed's actions,  as we believe there may be at
least one more interest rate hike in store before they are comfortable  with the
rate of U.S. economic growth. Our entry into interest-sensitive  sectors such as
financial services will hinge largely on future Fed actions.

Thank you for investing in Lord Abbett  Research  Fund. We value the  confidence
you place in us and look forward to serving your  investment  needs in the years
to come.

and  appropriate  Rule 12b-1 Plan expenses from  commencement  of the Plan. Past
performance  is no  indication  of  future  results.  Tax  consequences  are not
reflected.  The  investment  return and principal  value of an  investment  will
fluctuate so that shares,  on any given day or when redeemed,  may be worth more
or less than their  original  cost.  Each Series  issues  additional  classes of

1. Significant Accounting Policies

Lord Abbett  Research  Fund,  Inc. (the  "Company")  is an open-end  manage ment
investment  company  incorporated  under  Maryland  law on April 26,  1992.  The
Company  consists of three  separate  portfolios.  This report covers two of the
portfolios ("Series") - Small-Cap Value Series and Large-Cap Series. Each Series
is  diversified  as  defined  under  the  Investment  Company  Act of 1940.  The
financial statements have been prepared in conformity with accounting principles
generally  accepted in the United States of America  which permit  management to
make certain estimates and assumptions at the date of the financial  statements.
The following summarizes the significant accounting policies of the Company:

(a) Securities are valued as follows: Portfolio securities listed or admitted to
trading  privileges on any national  securities  exchange are valued at the last
sales price on the principal  securities  exchange on which such  securities are
traded,  or, if there is no sale, at the mean between the last bid and ask price
on such exchange,  or, in the case of bonds, in the over-the-counter  market if,
in the judgment of the Company's officers,  that market more accurately reflects
the market value of the bonds.  Securities  traded only in the  over-the-counter
market  are  valued at the mean  between  the bid and ask  prices,  except  that
securities  admitted to trading on the NASDAQ  National Market System are valued
at the last sales  price if it is  determined  that such  price more  accurately
reflects the value of such securities. Short-term securities maturing in 60 days
or less are valued at amortized cost which approximates market value. Securities
for which market  quotations  are not  available  are valued at fair value under
procedures  approved  by the  Board of  Directors.  (b) It is the  policy of the
Company to meet the  requirements  of the Internal  Revenue Code  applicable  to
regulated  investment  companies  and to distribute  all of its taxable  income.
Therefore,   no  federal  income  tax  provision  is  required.  (c)  Investment
transactions  are accounted for on the date that the securities are purchased or
sold (trade date).  Realized gains and losses from investment  transactions  are
calculated on the identified cost basis.  Dividend income and  distributions  to
shareholders are recorded on the ex-dividend  date. Net investment income (other
than  distribution and service fees) and realized and unrealized gains or losses
are allocated to each class of shares based upon the relative  proportion of net
assets at the beginning of the day.

2. Management Fee and Other Transactions with Affiliates

The Company has a management  agreement with Lord,  Abbett & Co. ("Lord Abbett")
pursuant to which Lord Abbett  supplies the Company with  investment  management
services and executive and other  personnel,  pays the remuneration of officers,
provides  office space and pays for ordinary and  necessary  office and clerical
expenses  relating to  research,  statistical  work and the  supervision  of the
Company's  investment  portfolios.  The  management fee paid is based on average
daily net  assets  for each  month at the  annual  rate of .75 of 1%. At May 31,
2000,  management  fees payable were  $314,080  for  Small-Cap  Value Series and
$173,720 for Large-Cap Series.

Each Series of the Company  has Rule 12b-1 plans and  agreements  (the "Class A,
Class  B,  Class  C and  Class  P  Plans")  with  Lord  Abbett  Distributor  LLC
("Distributor"),  an  affiliate of Lord  Abbett.  Each Series makes  payments to
Distributor  which uses or passes on such payments to  authorized  institutions.
Pursuant to the Class A Plan, each Series pays Distributor (1) an annual service
fee of 0.25% of the  average  daily  net asset  value of Class A  shares,  (2) a
one-time distribution fee of up to 1% on certain qualifying purchases and

                                                                              15

(3) an annual  distribution fee of 0.10% of the average daily net asset value of
Class A shares.  Pursuant to the Class B Plan,  each Series pays  Distributor an
annual service and  distribution  fee of 0.25% and 0.75%,  respectively,  of the
average  daily net asset  value of the Class B shares.  Pursuant  to the Class C
Plan, each Series pays Distributor (1) a service fee and a distribution  fee, at
the time such shares are sold, not to exceed 0.25% and 0.75%,  respectively,  of
the net asset value of such  shares  sold and (2) at each  quarter end after the
first  anniversary of the sale of such shares,  a service fee and a distribution
fee at an  annual  rate not to  exceed  0.25% and  0.75%,  respectively,  of the
average annual net asset value of such shares outstanding. Pursuant to the Class
P Plan, each Series pays  Distributor an annual service and  distribution fee of
0.20% and 0.25%, respectively, of the average daily net asset value of the Class
P shares.  Class Y of each Series  does not have a Rule 12b-1  plan.  At May 31,

4. Distributions

Dividends  from net  investment  income are declared  annually for the Small-Cap
Value Series and semi-annually for the Large-Cap Series.  Net realized gain from
investment transactions, if any, is distributed to shareholders annually. At May
31, 2000, accumulated net realized gain (loss) for each Series was as follows:


--------------------------------------------------------------------------------
Small-Cap Value Series                                           $(21,549,575)

Large-Cap Series                                                   12,343,576
--------------------------------------------------------------------------------

Income and capital gain  distributions  are determined in accordance with income
tax   regulations   which  may  differ  from  methods  used  to  determine   the
corresponding  income and capital gain  amounts in  accordance  with  accounting
principles generally accepted in the United States of America.

At May 31, 2000, the  Small-CapValue  Series had a capital loss carry forward of
$39,011,713, of which $30,380,175 will expire in 2006 and $8,631,538 in 2007.


5. Purchases and Sales of Securities

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

Small-Cap Value                                  $197,996,217    $219,764,660

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

As of May 31, 2000, net unrealized  appreciation,  gross unrealized appreciation
and gross  unrealized  depreciation  of  investments  based on cost for  federal
income tax purposes were as follows:


                               Net Unrealized      Unrealized      Unrealized
Series                           Appreciation    Appreciation   (Depreciation)
--------------------------------------------------------------------------------

Small-Cap Value                   $42,187,656     $84,827,626    $(42,639,970)

Large-Cap                          28,241,826      38,261,451     (10,019,625)
--------------------------------------------------------------------------------

same as that used for financial reporting purposes.


6. Directors` Remuneration

The Directors of theCompany  associated with Lord Abbett and all officers of the
Company  receive no  compensation  from the Company for acting as such.  Outside
Directors'  fees and retirement  costs are allocated among all funds in the Lord
Abbett  group based on the net assets of each fund.  Directors'  fees payable at
May 31, 2000 under a deferred compensation plan, were $22,832.


7. Line of Credit

Each  Series,  along  with  certain  other  funds  managed by Lord  Abbett,  has
available a $200,000,000 unsecured revolving credit facility ("Facility"),  from
a consortium  of banks,  to be used for  temporary  or emergency  purposes as an
additional  source of  liquidity to fund  redemptions  of investor  shares.  Any
borrowings  under this Facility  will bear  interest at current  market rates as
defined in the  agreement.  The fee for this  Facility  was at an annual rate of
0.06% during the year ended November 30, 1999. Effective December 17, 1999, this
fee was increased to 0.09% per annum.  There were no loans outstanding  pursuant
to this  Facility at May 31,  2000,  nor was the  Facility  utilized at any time
during the period.


8. Expense Reduction

The Company has entered  into an  arrangement  with its transfer  agent  whereby
credits  realized as a result of uninvested  cash balances were used to reduce a
portion of the Company's expenses.
