HOW WE INVEST

     We primarily invest in common stocks of midsized companies while utilizing
a value approach to investing. The Fund generally focuses on companies with
market capitalizations of roughly $500 million to $5 billion, but not less than
approximately $50 million. Selection of stocks is based on appreciation
potential, without regard to current income. Normally, at least 65% of our total
assets will consist of investments in mid-cap companies, determined at the time
of purchase.

     Our investment portfolio is diversified among many issues representing
various industries. The holdings in our portfolio typically are selected for
their potential for significant market appreciation from growing recognition of
substantial improvement in the Company's financial results or increasing
anticipation of such improvement. This potential may derive from such factors as
(i) changes in the economic and financial environment, (ii) new or improved
products or services, (iii) new or rapidly expanding markets, (iv) changes in
management or structure of the company, (v) price increases, (vi) improved
efficiencies resulting from new technologies or changes in distribution or (vii)
changes in governmental regulations, political climate or competitive
conditions.

     See "Investment Policies, Risks and Limits."

- --------------------------------------------------------------------------------
RISK FACTORS

The value of your investment will fluctuate in response to stock market
movements. The Fund employs other investment practices such as investments in
foreign securities and other securities, that could adversely affect
performance. Before you invest, please read "Investment Policies, Risks and
Limits."

- --------------------------------------------------------------------------------
PORTFOLIO MANAGEMENT

     Edward K. von der Linde, Executive Vice President and portfolio manager of
the Fund is primarily responsible for the day-to-day management of the Fund. Mr.
von der Linde has been with Lord Abbett since 1988 and has over 12 years of
investment experience. Mr. von der Linde is assisted by Howard E. Hansen.

Example

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

- --------------------------------------------------------------------------------
Share Class                         1 Year     3 Years     5 Years     10 Years
- --------------------------------------------------------------------------------
Class A shares                        $70         $95        $122        $200
Class B shares(2)                     $70         $93        $128        $213
Class C shares                        $30         $63        $108        $233
Class P shares                        $15         $46         $79        $174

You would pay the following expenses on the same investment, assuming you kept
your shares:

Class A shares                        $70         $95        $122        $200
Class B shares(2)                     $20         $63        $108        $213
Class C shares                        $20         $63        $108        $233
Class P Shares                        $15         $46         $79        $174

This example is for comparison and is not a representation of the Fund's actual
expenses and returns, either past or present.

(1)  Because of the 12b-1 fee, long-term shareholders may indirectly pay more
     than the equivalent of the maximum permitted front-end sales charge.
(2)  Class B shares will automatically convert to Class A shares on the eighth
     anniversary of your original purchase of Class B shares.

purchase order submitted in proper form, plus a front-end sales charge as
described below, in the case of the Class A shares and without a front-end sales
charge, in the case of the Class B, C and P shares as described below. Investors
should read this section carefully to determine which class of shares represents
the best investment option for their particular situation.

          any Eligible Fund over a 13-month period and receive the same sales
          charge as if all shares had been purchased at once. Shares purchased

     distribution under Retirement Plans (documentation may be required).

SHAREHOLDER SERVICES

Telephone Exchanges. You or your investment professional, with proper
identification, can instruct the Fund by telephone to exchange shares of any
class for the same class of any Eligible Fund. Instructions must be received by
the Fund in Kansas City by calling 1-800-821-5129 prior to the close of the New
York Stock Exchange ("NYSE") to obtain an Eligible Fund's NAV per class share on
that day. Exchanges will be treated as a sale for federal tax purposes.

     For your protection, telephone requests for exchanges are recorded. We will
take measures to verify the identity of the caller, such as asking for your
name, account number, social security or taxpayer identification number and
other relevant information. The Fund will not be liable for following
instructions communicated by telephone that it reasonably believes to be
genuine.

     Expedited exchanges by telephone may be difficult to implement in times of
drastic economic or market change. The exchange privilege should not be used to
take advantage of short-term swings in the market. The Fund reserves the right
to limit or terminate this privilege for any shareholder making frequent
exchanges and may revoke the privilege for all shareholders upon 60 days' prior
written notice. You have this privilege unless you refuse it in writing. 

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

subsequent minimum) into the Fund by means of automatic money transfers from
your bank checking account. See the attached Application Form for instructions.

the money from your bank.

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

     With respect to Class B shares, the CDSC will be waived on redemptions of

request. For Class B share redemptions over 12% per year, the CDSC will apply to
the entire redemption. Please contact the Fund for assistance in minimizing the
CDSC in this situation.

involved must have the same registration.

Pricing Shares. The net asset value ("NAV") per share for each class of shares
is calculated each business day at the close of regular trading on the New York
Stock Exchange ("NYSE") by dividing a class's net assets by the number of shares
outstanding. The Fund is open on those business days when the NYSE is open.

DIVIDENDS AND CAPITAL GAINS

Dividends. The Fund distributes most or all of its net earnings in the form of
dividends which are expected to be paid to shareholders annually in December.

Capital Gains Distributions. Any capital gains are paid at least annually and
may be taken in cash or reinvested. A second distribution may be made in order
to comply with Federal income tax requirements that a certain percentage of
capital gains be distributed during the year. Distributions by the Fund of any
net long-term capital gains will be taxable to a shareholder as long-term
capital gains regardless of how long the shareholder has held the shares. Under
recently enacted legislation, the maximum tax rate on long-term capital gains
for a U.S. individual, estate or trust is reduced to 20% for distributions
derived from the sale of assets held by the Fund for more than 18 months. (If
the taxpayer is in the 15% tax bracket, the rate is 10%.) For distributions
derived from the sale of assets held by the Fund between 12 and 18 months, the
tax rate remains at 28% (15% if the taxpayer is in the 15% tax bracket).

Dividends/Capital Gains Receipt or Reinvestment. If you elect to receive
dividends or capital gains in cash, a check will be mailed to you as soon as
possible after the reinvestment date. If you arrange for direct deposit, your
payment will be electronically transmitted to your bank account within one day
after the payable date. Most investors reinvest their dividends and capital
gains. If you choose this option, or if you do not indicate any choice, your
dividends and capital gains distributions will be automatically reinvested in
additional shares.

Taxes. The Fund pays no federal income tax on the earnings it distributes to
shareholders. Consequently, dividends you receive from the Fund, whether
reinvested or taken in cash, are generally considered taxable. Dividends
declared in October, November or December of any year will be treated for
federal income tax purposes as having been received by shareholders in that year
if they are paid before February 1 of the following year.

     Each January the Fund will mail to you, if applicable, a Form 1099 tax
information statement detailing your dividends and capital gain distributions.
You should consult you tax adviser concerning applicable state and local taxes.

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

- --------------------------------------------------------------------------------
OUR MANAGEMENT

     The Fund is supervised by a Board of Directors, an independent body which
has ultimate responsibility for the Fund's activities. The Board has retained
Lord Abbett as investment manager pursuant to a Management Agreement. Lord
Abbett has been an investment manager for over 69 years and currently manages
about $27 billion in a family of mutual funds and other advisory accounts. Lord
Abbett provides similar services to twelve other funds having various investment
objectives and also advises other investment clients. For more information about
the services Lord Abbett provides to the Fund, see the Statement of Additional
Information.

     The Fund pays Lord Abbett a monthly fee based on average daily net assets
for each month. For the fiscal year ended December 31, 1997, the fee paid to
Lord Abbett was at an annual rate of .72 of 1%. In addition, the Fund pays all
expenses not expressly assumed by Lord Abbett.

The Fund. The Fund is a diversified open-end management investment company
established in 1934. Its Class A, B, C and P shares have equal rights as to
voting, dividends, assets and liquidation except for differences resulting from
certain class-specific expenses.

- --------------------------------------------------------------------------------
FUND PERFORMANCE

     During the past fiscal year, the Fund performed well. We attribute these
strong returns to our continuing commitment to careful stock selection. The Fund
does not seek to emphasize particular sectors, but, instead, focuses on
investing in those companies we believe offer the best value in the
mid-capitalization sector (companies with market capitalizations ranging from
$500 million to $5 billion). At the close of the year, the Fund had strong
exposure to the insurance, specialty chemical and electric power sectors because
we identified a number of companies in those industries offering exceptional
value.

     See the performance chart on the second to last page of this Prospectus.


                                                                               9

INVESTMENT POLICIES, RISKS AND LIMITS

The Fund is permitted to utilize, within limits established by the Board of
Directors, the following investment policies in an effort to enhance the Fund's
performance. These policies have risks associated with them. However, the Fund
follows certain practices that may reduce these risks. To the extent the Fund
utilizes some of these policies, its overall performance may be positively or
negatively affected.

Securities Lending: The lending of securities to financial institutions which
provide continuous collateral equal to the market value of the securities
loaned.

Risk: Delay in recovery of collateral and loss should the borrower of the
security fail financially. Limit: Loans, in the aggregate, may not exceed 30% of
the Fund's total assets.

Foreign Securities: Foreign securities are securities primarily traded in
countries outside the United States.

Risk: These securities are not subject to the same degree of regulation and may
be more volatile and less liquid than securities traded in major U.S. markets.
Other considerations include political and social instability, expropriations,
higher transaction costs, currency fluctuations, nondeductible withholding taxes
and different settlement practices.

Limit: The Fund may invest up to 10% of its assets at the time of investment in
foreign securities.

Illiquid Securities: Securities not traded on the open market. May include
illiquid Rule 144A securities.

Risk: Certain securities may be difficult or impossible to sell at the time and
price the seller would like. Limit: The Fund may invest up to 15% of its assets
in illiquid securities. Securities determined by the Board of Directors to be
liquid are not subject to this limitation.

Objective, Restriction and Policy Changes. The Fund will not change its
investment objective or its fundamental restrictions without shareholder
approval. If the Fund determines that its objective can best be achieved by a
substantive change in investment policy, which may be changed without
shareholder approval, the Fund may make such change by disclosing it in the
prospectus.

For more information about investment policies, restrictions and risk factors,
see the Statement of Additional Information.

- --------------------------------------------------------------------------------
SALES COMPENSATION

As part of its plan for distributing shares, the Fund, along with Lord Abbett
Distributor, pays compensation to Authorized Institutions that sell the Fund's
shares. These firms typically pass along a portion of this compensation to your
financial representative.

Compensation payments originate from two sources: sales charges and 12b-1 fees
that are paid out of the Fund's assets ("12b-1"refers to the federal securities
regulation authorizing annual fees of this type). The 12b-1 fee rates vary by
share class, according to the Rule 12b-1 plan adopted by the Fund for each share
class. The sales charges and 12b-1 fees paid by investors are detailed in the
class-by-class information under "Investor Expenses" and "Purchases." The
portion of these expenses that are paid as compensation to Authorized
Institutions, such as your dealer, are shown in the chart on the last page of
this Prospectus. Sometimes compensation is not paid where tracking data is not
available for certain accounts and where the Authorized Institution waives part
or all of the compensation as with an account under a Mutual Fund Wrap-Fee
Program.

Rule 12b-1 distribution fees may be used to pay for sales compensation to
Authorized Institutions, for any activity which is primarily intended to result

GLOSSARY OF TERMS

Additional Concessions. A supplemental annual distribution fee equal to 0.10% of
the average daily net asset value of the Class A shares is available to
Authorized Institutions which have a program for the promotion and retention of
such shares satisfying Lord Abbett Distributor. Class A shares held pursuant to
a satisfactory program would, for example, (i) constitute a significant
percentage of the Fund's net assets, (ii) be held for a substantial length of
time and/or (iii) have a lower than average redemption rate.

     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. Lord Abbett Distributor may, from time to time, implement promotions
under which Lord Abbett Distributor will pay a fee to dealers with respect to
certain purchases not involving imposition of a sales charge. Additional
payments may be paid from Lord Abbett Distributor's own resources 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."

Eligible Fund. (a) Any Lord Abbett-sponsored fund except certain tax-free,
single-state series where the exchanging shareholder is a resident of a state in
which such series is not offered for sale; Lord Abbett Equity Fund; Lord Abbett
Series Fund; Lord Abbett Research Fund -- Mid-Cap Series; Lord Abbett U.S.


                                                                              11
<PAGE>

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). (b) Any Authorized Institution's affiliated money market fund satisfying
Lord Abbett Distributor as to certain omnibus account and other criteria.

Eligible Guarantor. 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.

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

Employees of Lord Abbett/Fund Directors (Trustees). The terms "directors,"
"trustees" (of a Fund) and "employees" (of Lord Abbett) include a director's
(trustee's) or employee's spouse (including the surviving spouse of a deceased
director (trustee) or employee). The terms "directors," "trustees" and
"employees of Lord Abbett" also include other family members and retired
directors (trustees) and employees.

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.

     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.

The performance of the Class A shares which is shown in the comparison below
will be greater than or less than that for Class B, C and P shares based on the
differences in sales charges and fees paid by shareholders investing in the
different classes.

Comparison of change in value of a $10,000 investment in Class A shares in the
Fund, assuming reinvestment of all dividends and distributions and the unmanaged
Russell Mid-Cap Index.

(1)  The service fee for Class A and P shares is paid quarterly and for Class A
     shares may not exceed 0.15% if sold prior to June 1, 1990. 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 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 statement
     of intention privileges are included and(b) for Special Retirement Wrap
     Programs, only new sales are eligible and exchanges into the Fund are
     excluded.

(4)  With respect to Class B, C and P shares, 0.25%, 1.00% 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. With repect to
     shares, CDSC revenues collected may be used to fund commission payments
     when there is no initial sales charge.

                                   Lord Abbett
- --------------------------------------------------------------------------------
                            Mid-Cap Value Fund, Inc.

This Statement of Additional Information is not a Prospectus. A Prospectus may
be obtained from your securities dealer or from Lord Abbett Distributor LLC
("Lord Abbett Distributor") at The General Motors Building, 767 Fifth Avenue,
New York, New York 10153-0203. This Statement relates to, and should be read in
conjunction with, the Prospectus dated May 1, 1998.

Lord Abbett Mid-Cap Value Fund, Inc. (sometimes referred to as "we" or the
"Fund") was incorporated under Maryland law on March 14, 1983. The Fund's Board
of Directors has authority to create and classify shares of common stock into
separate series, without further action by shareholders. The Fund currently has
150,000,000 shares of authorized capital stock consisting of four classes (A, B,
C and P) at $0.001 par value. The Board of Directors will allocate these
authorized shares 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.
Although no present plans exist to do so, further series may be added in the
future. The Investment Company Act of 1940, as amended (the "Act"), requires
that where more than one series exists, each series must be preferred over all
other series in respect of assets specifically allocated to such series.

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

Shareholder inquiries should be made by writing directly to the Fund or by
calling 800-821-5129. In addition, you can make inquiries through Lord Abbett
Distributor.

Fundamental Investment Restrictions

We are subject to the following investment restrictions which cannot be changed
without approval of a majority of our outstanding shares. The Fund may not: (1)

Investment Company Act of 1940, as amended (the "Act")) in amounts up to 33 1/3%
of its total assets (including the amount borrowed), (ii) the Fund may borrow up
to an additional 5% of its total assets for temporary purposes, (iii) the Fund

assets (other than to secure borrowings, or to the extent permitted by the
Fund's investment policies as permitted by applicable law); (3) engage in the
underwriting of securities, except pursuant to a merger or acquisition or to the
extent that, in connection with the disposition of its portfolio securities, it
may be deemed to be an underwriter under federal securities laws; (4) make loans
to other persons, except that the acquisition of bonds, debentures or other
corporate debt securities and investment in government obligations, commercial
paper, pass-through instruments, certificates of deposit, bankers acceptances,
repurchase agreements or any similar instruments shall not be subject to this
limitation, and except further that the Fund may lend its portfolio securities,
provided that the lending of portfolio securities may be made only in accordance
with applicable law; (5) buy or sell real estate (except that the 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)
or commodities or commodity contracts (except to the extent the 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 of the Fund, 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 securities of the
U.S. Government, its agencies and instrumentalities); or (8) issue senior
securities to the extent such issuance would violate applicable law.

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

Non-Fundamental Investment Restrictions. In addition to the investment
restrictions above which cannot be changed without shareholder approval, we also
are subject to the following non-fundamental investment policies which may be
changed by the Board of Directors without shareholder approval. The Fund may
not: (1) borrow in excess of 33 1/3% of its total assets (including the amount
borrowed), and then only as a temporary measure for extraordinary or emergency
purposes; (2) make short sales of securities or maintain a short position except
to the extent permitted by applicable law; (3) invest knowingly more than 15% of
its net assets (at the time of investment) in illiquid securities, except for
securities qualifying for resale under Rule 144A of the Securities Act of 1933,
deemed to be liquid by the Board of Directors; (4) invest in the securities of
other investment companies except as permitted by applicable law; (5) invest in
securities of issuers which, with their predecessors, have a record of less than
three years' continuous operations, if more than 5% of the Fund's total assets
would be invested in such securities (this restriction shall not apply to
mortgage-backed securities, asset-backed securities or obligations issued or
guaranteed by the U. S. Government, its agencies or instrumentalities); (6) hold
securities of any issuer if more than 1/2 of 1% of the securities of such issuer
are owned beneficially by one or more officers or directors of the Fund or by
one or more partners or members of the Fund's underwriter or investment adviser
if these owners in the aggregate own beneficially more than 5% of the securities
of such issuer; (7) invest in warrants if, at the time of the acquisition, its
investment in warrants, valued at the lower of cost or market, would exceed 5%
of the Fund's total assets (included within such limitation, but not to exceed
2% of the Fund's total assets, are warrants which are not listed on the New York
or American Stock Exchange or a major foreign exchange); (8) invest in real
estate limited partnership interests or interests in oil, gas or other mineral
leases, or exploration or other development programs, except that the Fund may
invest in securities issued by companies that engage in oil, gas or other
mineral exploration or other development activities; (9) 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 (10) buy from or sell to 


                                       2
<PAGE>

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

Under normal circumstances, at least 65% of the Fund's total assets will consist
of investments in mid-cap companies, determined at the time of purchase.
"Mid-cap" companies are defined for this purpose as companies whose outstanding
equity securities have an aggregate market value of between $500,000,000 and
$5,000,000,000.

Although it has no current intention to do so, the Fund may invest in financial
futures and options on financial futures.

Portfolio Turnover Rate. For the fiscal year ended December 31, 1997, our
portfolio turnover rate was 56.96% compared to 38.88% for the prior fiscal year.

(1)   Outside directors' fees, including attendance fees for board and committee
      meetings, are allocated among all Lord Abbett-sponsored funds based on the
      net assets of each fund. A portion of the fees payable by the Fund to its
      outside directors/trustees is being deferred under a plan that deems the
      deferred amounts to be invested in shares of the Fund for later
      distribution to the directors/trustees.

(2)   The amounts in Column 3 were accrued by the Lord Abbett-Sponsored Funds
      for the 12 months ended October 31, 1997 with respect to the equity based
      plans established for independent directors in 1996. This plan supercedes
      a previously approved retirement plan for all future directors. Current
      directors had the option to 


                                       4
<PAGE>

      convert their accrued benefits under the retirement plan. All of the
      outside directors except one made such an election. Each plan also
      provides for a pre-retirement death benefit and actuarially reduced
      joint-and-survivor spousal benefits.

     (3)  This column shows aggregate compensation, including directors fees and
          attendance fees for board and committee meetings, of a nature referred
          to in footnote one, accrued by the Lord Abbett-sponsored  funds during
          the year  ended  December  31,  1997.  The  amounts  of the  aggregate
          compensation  payable  by the  Fund as of  December  31,  1997  deemed
          invested in Fund shares, including dividends reinvested and changes in
          net asset value  applicable  to such  deemed  investments,  were:  Mr.
          Bigelow,  $3,646;  Mr.  Dixon,  $57,494;  Mr.  Jansing,  $60,671;  Mr.
          MacDonald,  $20,575; Mr. Millican,  $62,256; and Mr. Neff, $62,566. If
          the  amounts  deemed  invested  in  Fund  shares  were  added  to each
          director's actual holdings of Fund shares as of December 31, 1997 each
          would own, the  following:  Mr.  Bigelow,  60 shares;  Mr.  Dixon,  88
          shares;  Mr. Jansing,  4,479 shares;  Mr. MacDonald,  61.5 shares; Mr.
          Millican, 59 shares; and Mr. Neff, 933 shares.

(4)   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. Of the following, Messrs.
Carper, Hilstad, Morris, and Walsh are partners of Lord Abbett; the others are
employees: Edward K. von der Linde, age 37, Executive Vice President; Paul A.
Hilstad, age 55, Vice President and Secretary (with Lord Abbett since 1995;
formerly Senior Vice President and General Counsel of American Capital
Management & Research, Inc.); Daniel E. Carper, age 46; Lawrence H. Kaplan, age
41 (with Lord Abbett since 1997 - formerly Vice President and Chief Counsel of
Salomon Brothers Asset Management Inc from 1995 to 1997, prior thereto Senior
Vice President, Director and General Counsel of Kidder Peabody Asset Management,
Inc. from 1990 to 1995); Thomas F. Konop, age 56; Robert G. Morris, age 53; A.
Edward Oberhaus, age 38; Keith F. O'Connor, age 42; John J. Walsh, age 62, Vice
Presidents; and Donna M. McManus, age 37, Treasurer (with Lord Abbett since
1996, formerly a Senior Manager at Deloitte & Touche LLP).

The Fund's By-Laws provide that the Fund shall not hold an annual meeting of its
stockholders in any year unless one or more matters are required to be acted on
by stockholders under the Investment Company Act of 1940, as amended (the
"Act"), or unless called by a majority of the Board of Directors or by
stockholders holding at least one quarter of the stock of the Fund outstanding
and entitled to vote at the meeting. When any such annual meeting is held, the
stockholders will elect directors and vote on the approval of the independent
auditors of the Fund.

As of April 1, 1998, our officers and directors, as a group, owned less than 1%
of our outstanding shares.

                                       3.
                     Investment Advisory and Other Services

As described under "Our Management" in the Prospectus, Lord Abbett is the Fund's
investment  manager.  Six of the  twelve  general  partners  of Lord  Abbett are
officers and/or  directors of the Fund and are identified as follows:  Daniel E.
Carper, Robert S. Dow, Paul A. Hilstad,  Robert G. Morris, E. Wayne Nordberg and
John J. Walsh.  The six other  general  partners  are Stephan I. Allen,  Zane E.
Brown, Daria L. Foster, W. Thomas Hudson,  Michael McLaughlin,  Robert J. Noelke
and E. Wayne  Nordberg.  The  address  of each  partner  is The  General  Motors
Building, 767 Fifth Avenue, New York, New York 10153-0203.

The services performed by Lord Abbett are described in the Prospectus under "Our
Management". Under the Management Agreement, we pay Lord Abbett a monthly fee,
based on average daily net assets for each month, at the annual rate of .75 of
1% of the portion of our net assets not in excess of $200,000,000; .65 of 1% of
the portion in excess of $300,000,000 but not in excess of $500,000,000; and .50
of 1% of the portion in excess of $500,000,000. For the fiscal years ended
December 31, 1997, 1996 and 1995, the management fees paid to Lord Abbett
amounted to $2,102,611, $1,733,689 and $1,584,007, respectively.


                                       5
<PAGE>

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

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

The Bank of New York ("BNY"), 48 Wall Street, New York, New York 10286, is the
Fund's custodian. In accordance with the requirements of Rule 17f-5 under the
Act, the Fund's directors have approved arrangements permitting the Fund's
foreign assets not held by BNY or its foreign branches to be held by certain
qualified foreign banks and depositories.

                                       4.
                             Portfolio Transactions

Our policy is to obtain best execution on all our portfolio transactions, which
means that we seek to have purchases and sales of portfolio securities executed
at the most favorable prices, considering all costs of the transaction including
brokerage commissions and dealer markups and markdowns 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 transactions. Our 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 the 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 pay a commission rate that we believe is appropriate to give maximum
assurance that our brokers will provide us, on a continuing basis, the highest
level of brokerage services available. While we do not always seek the lowest
possible commissions on particular trades, we believe that our commission rates
are in line with the rates that many other institutions pay. Our traders are
authorized to pay brokerage commissions in excess of those that other brokers
might accept on the same transactions in recognition of the value of the
services performed by the executing brokers, viewed in terms of either the
particular transaction or the overall responsibilities of Lord Abbett with
respect to us and the other accounts they manage. Such services include showing
us trading opportunities including blocks, a willingness and ability to take
positions in securities, knowledge of a particular security or market proven
ability to handle a particular type of trade, confidential treatment, promptness
and reliability.

Some of these brokers 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 the furnishing of analyses and
reports concerning issuers, industries, securities, economic factors and trends,
portfolio strategy and the performance of accounts and trading equipment and
computer software packages, acquired from third-party suppliers, that enable
Lord Abbett to access various information bases. 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 


                                       6
<PAGE>

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 Fund 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 our shares and/or
shares of other Lord Abbett-sponsored funds may be preferred.

If other clients of Lord Abbett buy or sell the same security at the same time
as we do, 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 we do, 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 we do.

We will not seek "reciprocal" dealer business (for the purpose of applying
commissions in whole or in part for our benefit or otherwise) from dealers as
consideration for the direction to them of portfolio business.

During the fiscal years ended December 31, 1997, 1996 and 1995, we paid total
commissions to independent broker-dealers of $992,190, $554,002 and $586,752,
respectively.

                                       5.
                             Purchases, Redemptions
                            and Shareholder Services

Information concerning how we value our shares for the purchase and redemption
of our shares is contained 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 Directors.

The maximum offering price of Class A shares on December 31, 1997 was computed
as follows:

                                                                    Class A
                                                                    -------
Net asset value per share (net assets divided
by shares outstanding)                                              $13.37

Maximum offering price per share (net asset
value divided by .9425)                                             $14.19

The net asset value per share for the Class B and C shares will be determined in
the same manner as for the Class A shares (net assets divided by shares
outstanding). Our Class B and C shares will be offered at net asset value.

The Fund has entered into a distribution agreement with Lord Abbett Distributor
LLC, a New York limited liability company ("Lord Abbett Distributor") and
subsidiary of Lord Abbett under which Lord Abbett Distributor is obligated to
use its best efforts to find purchasers for the shares of the Fund, 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.

For the last three fiscal years, Lord Abbett, as our principal underwriter,
received net commissions after allowance of a portion of the sales charge to
independent dealers as follows:

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 or tax adviser, 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. The Fund offers investors five different classes of shares.
This Prospectus offers four of those classes designated Class A, B and C. 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.

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 


                                       8
<PAGE>

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 approximately .25 of 1% of the annual net asset value of the
Class A shares. The initial sales charge rates, the CDSC and the Rule 12b-1 plan
applicable to the Class A shares are described in "Buying Class A Shares" 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 LLC ("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 in "Buying Class B
Shares" 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 in "Buying Class C Shares" 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 the 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 the 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 


                                       9
<PAGE>

Class C shares, and the CDSC does not apply to amounts you redeem after holding
them one year.

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 investment professional.

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 "Shareholder Services" 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.

Class A, B and C Rule 12b-1 Plans. As described in the Prospectus, the Fund has
adopted a Distribution Plan and Agreement pursuant to Rule 12b-1 of the Act for
each of the three Fund Classes: the "A Plan", the "B Plan" and the "C Plan",
respectively. In adopting each Plan and in approving its continuance, the Board
of Directors has concluded that there is a reasonable likelihood that each Plan
will benefit its respective Class and such Class' shareholders. The expected
benefits 


                                       10
<PAGE>

include greater sales and lower redemptions of Class 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.
During the last fiscal year, the Fund accrued or paid through Lord Abbett to
authorized institutions $580,000 under the A Plan. The B Plan and the C Plan
will go into effect on or about May 1, 1997. Lord Abbett used all amounts
received under the A Plan for payments to dealers for (i) providing continuous
services to the Class A 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 Class A shares of the Fund.

Each Plan requires the directors to review, on a quarterly basis, written
reports of all amounts expended pursuant to the Plan and the purposes for which
such expenditures were made. Each Plan shall continue in effect only if its
continuance is specifically approved at least annually by vote of the directors,
including a majority of the directors who are not interested persons of the Fund
and who have no direct or indirect financial interest in the operation of 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 thereunder 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")
(i) applies regardless of class, (ii) will not apply to shares purchased by the
reinvestment of dividends or capital gains distributions; (iii) 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 (iv) will not be imposed on (a) the aggregate
dollar amount of your account, in the case of Class A shares, and (b) the
percentage of each share redeemed, in the case of class B and C shares,
representing an 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, CDSC
of 1% is imposed with respect to those Class A shares (or Class A shares of
another Lord Abbett-sponsored fund or series acquired through exchange of such
shares) on which the 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 (or Class B shares of another Lord Abbett-sponsored fund or
series 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, for 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 Fund redeems 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:

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


                                       11
<PAGE>

In the table, an "anniversary" is the 365th day subsequent to the acceptance of
a purchase order or a prior anniversary. 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 this 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."

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. With respect to Class A shares
purchased pursuant to a special retirement wrap program, no CDSC is payable on
redemptions which continue as investments in another fund participating in the
program. With respect to Class B shares, no CDSC is payable for redemptions (i)
in connection with Systematic Withdrawal Plan and Div-Move services as described
below under those headings, (ii) in connection with mandatory distribution under
403(b) plans and IRAs and (iii) in connection with death of the shareholder. In
the case of Class A and Class C shares, the CDSC is received by the 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 and series which participate in the Telephone Exchange Privilege
(except (a) Lord Abbett U.S. Government Securities Money Market Fund, Inc.
("GSMMF"), (b) certain series of Lord Abbett Tax-Free Income Fund 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.


                                       12
<PAGE>

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) shares
representing an aggregate dollar amount of your account, in the case of Class A
shares, (ii) that percentage of each share redeemed, in the case of Class B and
C shares, derived from increases in the value of the shares above the total cost
of shares being redeemed due to increases in net asset value, (iii) shares with
respect to which no Lord Abbett 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 (iv) 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) and 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 of any class for those in 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 fund 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 other 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 corresponding class of 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 in a Lord Abbett-sponsored
fund). 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.

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, Lord Abbett
Equity Fund (" LAEF") which is not issuing shares, and series of Lord Abbett
Research Fund not offered to the general public ("LARF").

Statement of Intention. Under the terms of the Statement of Intention to invest
$50,000 or more over a 13-month period as described in the Prospectus, in shares
of a Lord Abbett-sponsored fund (other than shares of LAEF, LASF, LARF, GSMMF
and AMMF, unless holdings in GSMMF and AMMF are attributable to shares exchanged
from a Lord Abbett-sponsored fund offered with a front-end, back-end or level
sales charge) shares currently owned by you are credited as purchases (at their
current offering prices on the date the Statement is signed) toward achieving
the stated investment and reduced initial sales charge 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 Statement is not
completed. The Statement 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 LAEF, LARF, LASF, GSMMF, and AMMF unless holdings in GSMMF or AMMF
are attributable to shares exchanged from a Lord Abbett-sponsored fund offered
with a front-end, back-


                                       13
<PAGE>

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 director 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 "our directors" and "employees of Lord
Abbett" also include retired directors and employees and other family members
thereof.

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 of other Lord
Abbett-sponsored funds, except for LARF, LAEF and 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, ("mutual fund wrap fee program"), (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, and
(g) through a "special retirement wrap program" sponsored by an authorized
institution having one or more characteristics distinguishing it, in the opinion
of Lord Abbett Distributor, from a mutual fund wrap 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 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.

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

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

Our Board of Directors may authorize redemption of all of the shares in any
account in which there are fewer than 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 day's 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 of any class into an existing account of the
same class in any other Eligible Fund. The account must be either your account,
a joint account for you and your spouse, a single account for your spouse, or a
custodial account for your minor child under the age of 21. You should read the
prospectus of the other fund before investing.

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

Systematic Withdrawal Plans. The Systematic Withdrawal Plan ("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
Class B shares the CDSC will be waived on redemptions of up to 12% per year of
the current net asset value of your account at the time the SWP is established.
For Class B share redemptions over 12% per year, the CDSC will apply to the
entire redemption. Therefore, please contact the Fund for assistance in
minimizing the CDSC in this situation. 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 including 401(k) plans and custodial agreements for
IRAs (Individual Retirement Accounts, including SIMPLE IRAs and Simplified
Employee Pensions), 403(b) plans and qualified pension and profit-sharing plans.
The forms name Investors Fiduciary Trust Company as custodian except in the case
of 401(k) plans 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.

                                Past Performance

The Fund computes the average annual compounded rate of total return 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 from the initial 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(s) 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 the
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.

Using the computation method described above, the Fund's average annual
compounded rates of total return for the last one-, five-, and ten-year period
ending on December 31, 1997 were as follows: 23.90%, 15.86% and 14.87% for the
Fund's Class A shares, respectively. For the Fund's Class B shares, the average
annual compounded rate of total return for the life-of-the-


                                       15
<PAGE>

Fund period ending on December 31, 1997 was: 21.13%. For the Fund's Class C
shares, the average annual compounded rate of total return for the
life-of-the-Fund period ending on December 31, 1997 was: 26.23%.

These figures represent past performance, and an investor should be aware that
the investment return and principal value of a Fund investment will fluctuate so
that an investor's shares, when redeemed, may be worth more or less than their
original cost. Therefore, there is no assurance that this performance will be
repeated in the future.

                                       7.
                                      Taxes

The value of any shares redeemed by the Fund or otherwise sold may be more or
less than your tax basis in the shares at the time the redemption or sale is
made. Any gain or loss generally will be taxable for federal income tax
purposes. Any loss realized on the sale or redemption of Fund shares which you
have held for six months or less will be treated for tax purposes as a long-term
capital loss to the extent of any capital gains distributions which you received
with respect to such shares. Losses on the sale of stock or securities 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 stock or
securities that are substantially identical.

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

As described in the Prospectus under "Risk Factors", the Fund may be subject to
foreign withholding taxes which would reduce the yield on its investments. Tax
treaties between certain countries and the United States may reduce or eliminate
such taxes. It is expected that Fund 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.

Gains and losses realized by the 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 gains or losses are 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
gains and will be reduced by the net amount, if any, of such foreign exchange
losses.

If the Fund purchases shares in certain foreign investment entities, called
"passive foreign investment companies," it 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 either the Fund or its shareholders with respect to
deferred taxes arising from such distributions or gains. If the Fund were to
invest in a passive foreign investment company with respect to which the Fund
elected to make a "qualified electing fund" election in lieu of the foregoing
requirements, the 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.

Dividends paid by the Fund will qualify for the dividends-received deduction for
corporations to the extent they are derived from dividends paid by domestic
corporations.

The foregoing discussion relates solely to U. S. federal income tax law as
applicable to United States persons (United States citizens or residents and
United 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
the Fund, including a 30% (or lower treaty rate) United States withholding tax
on dividends representing ordinary income and net short-term capital gains, and
the applicability of United States gift and estate taxes to non-United States
persons who own Fund shares.

                           Information About the Fund

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

Item 27. Indemnification

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



<PAGE>



                                                         2

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

         In referring in its By-Laws to, and making indemnification of directors
         subject to the conditions and limitations of, both Section 2-418 of the
         Maryland Law and Section 17(h) of the  Investment  Company Act of 1940,
         Registrant intends that conditions and limitations on the extent of the
         indemnification  of  directors  imposed  by the  provisions  of  either
         Section 2-418 or Section  17(h) shall apply and that any  inconsistency
         between the two will be resolved by  applying  the  provisions  of said
         Section 17(h) if the  condition or limitation  imposed by Section 17(h)
         is the more  stringent.  In referring in its By-Laws to SEC Release No.
         IC-11330 as the source for  interpretation  and  implementation of said
         Section 17(h),  Registrant  understands that it would be required under
         its By-Laws to use  reasonable  and fair means in  determining  whether
         indemnification  of a  director  should be made and  undertakes  to use
         either  (1) a final  decision  on the  merits by a court or other  body
         before  whom  the   proceeding  was  brought  that  the  person  to  be
         indemnified  ("indemnitee")  was not  liable  to  Registrant  or to its
         security  holders by reason of willful  malfeasance,  bad faith,  gross
         negligence, or reckless disregard of the duties involved in the conduct
         of his office  ("disabling  conduct")  or (2) in the  absence of such a
         decision, a reasonable determination, based upon a review of the facts,
         that the indemnitee was not liable by reason of such disabling conduct,
         by (a) the vote of a majority of a quorum of directors  who are neither
         "interested  persons"  (as defined in the 1940 Act) of  Registrant  nor
         parties to the  proceeding,  or (b) an  independent  legal counsel in a
         written opinion. Also, Registrant will make advances of attorneys' fees
         or other  expenses  incurred by a director  in his defense  only if (in
         addition  to  his  undertaking  to  repay  the  advance  if he  is  not
         ultimately entitled to  indemnification)  (1) the indemnitee provides a
         security for his  undertaking,  (2) Registrant shall be insured against
         losses arising by reason of any lawful advances, or (3) a majority of a
         quorum of the non-interested,  non-party directors of Registrant, or an
         independent legal counsel in a written opinion, shall determine,  based
         on a review of readily available facts, that there is reason to believe
         that   the   indemnitee   ultimately   will  be   found   entitled   to
         indemnification.

         Insofar as  indemnification  for liability arising under the Securities
         Act of 1933 may be permitted  to  directors,  officers and  controlling
         persons of the  Registrant  pursuant to the  foregoing  provisions,  or
         otherwise,  the  Registrant has been advised that in the opinion of the
         Securities  and Exchange  Commission  such  indemnification  is against
         public policy as expressed in the Act and is, therefore, unenforceable.
         In the event that a claim for indemnification  against such liabilities
         (other than the payment by the  Registrant of expense  incurred or paid
         by a director,  officer or controlling  person of the Registrant in the
         successful  defense of any action,  suit or  proceeding) is asserted by
         such  director,  officer or controlling  person in connection  with the
         securities being registered, the Registrant will, unless in the opinion
         of its counsel the matter has been  settled by  controlling  precedent,
         submit to a court of appropriate jurisdiction the question whether such
         indemnification  by it is against public policy as expressed in the Act
         and will be governed by the final adjudication of such issue.

         In addition,  Registrant maintains a directors' and officers errors and
         omissions liability insurance policy protecting  directors and officers
         against liability for breach of duty,  negligent act, error or omission
         committed  in their  capacity  as  directors  or  officers.  The policy
         contains certain exclusions, among which is exclusion from coverage for
         active or  deliberate  dishonest or  fraudulent  acts and exclusion for
         fines or penalties imposed by law or other matters deemed uninsurable.

do in any part of the world, and to engage in any lawful act or activity for

            The foregoing objects and purposes shall, except as otherwise

inference from the terms of any other clause of this or any other Article of
these Articles of Incorporation, and shall each be regarded as independent, and
construed as powers as well as objects and purposes, and the enumeration of
specific purposes, objects and powers shall not be construed to limit or
restrict in any manner the meaning of general terms or the general powers of the

shall the expression of one thing be deemed to exclude another, though it be of
like nature, not expressed; provided, however, that the Corporation shall not

                                   ARTICLE VI

            SECTION 1. The total number of shares which the Corporation has
authority to issue is 150,000,000 shares of capital stock of the par value of
$.001 each, having an aggregate par value of $150,000. The Board of Directors of
the Corporation shall have full power and authority, from time to time, to
classify or reclassify any unissued shares of stock of the Corporation,
including, without limitation, the power to classify or reclassify unissued
shares into series, and to classify or reclassify a series into one or more
classes of stock that may be invested together in the common investment
portfolio in which the series is invested, by setting or changing the
preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends, qualifications, or terms or conditions of
redemption of such shares of stock. All shares of stock of a series shall
represent the same interest in the Corporation and have the same preferences,
conversion or other rights, voting powers, restrictions, limitations as to
dividends, qualifications, or terms or conditions of redemption as the other
shares of stock of that series, except to the extent that the Board of Directors
provides for differing preferences, conversion or other rights, voting powers,
restrictions limitations as to dividends, qualifications, or terms or conditions
of redemption of shares of stock of classes of such series as determined
pursuant to Articles Supplementary filed for record with the State 


                                       3
<PAGE>

Department of Assessments and Taxation of Maryland, or as otherwise determined
pursuant to these Articles or by the Board of Directors in accordance with law.
Prior to the first classification of unissued shares of stock into additional
series, all outstanding shares of stock shall be of a single series, and prior
to the first classification of a series into additional classes, all outstanding
shares of stock of such series shall be of a single class. Nothwithstanding any
other provision of these Articles, upon the first classification of unissued
shares of stock into additional series, the Board of Directors shall specify a
legal name for the outstanding series, as well as for the new series, in
appropriate charter documents filed for record with the State Department of
Assessments and Taxation of Maryland providing for such name change and
classification, and upon the first classification of a series into additional
classes, the Board of Directors shall specify a legal name for the outstanding
class, as well as for the new class or classes, in appropriate charter documents
filed for record with the State Department of Assessments and Taxation of
Maryland providing for such name changes and classification.

      [On April 16, 1997, the Articles of Incorporation of the Corporation were
further supplemented by the filing of Articles Supplementary with the State
Department of Assessments and Taxation of Maryland which specified the legal
name for the existing class of the Corporation, both outstanding shares and
unissued shares, as Class A.

      On April 16, 1997, the Articles of Incorporation of the Corporation were
further supplemented by the filing of Articles Supplementary with the State
Department of Assessments and Taxation of Maryland which pursuant to the
authority of the Board of Directors of the Corporation to classify and
reclassify a series into one or more classes of such series, the Board of
Directors (i) classified 15,000,000 authorized, but unissued Class A shares as
Class C shares and (ii) classified 15,000,000 authorized, but unissued Class A
shares as Class B shares. Such Articles Supplementary further provided that
subject to the power of the Board of Directors to classify and reclassify
unissued shares, all shares of the Class B and C stock shall be invested in the
same investment portfolio of the Corporation as the Class A stock and shall have
the same preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends, qualifications, and terms and conditions of
redemption set forth in Article V of the Articles of Incorporation of the
Corporation and shall be subject to all other provisions of the Articles of
Incorporation relating to stock of the Corporation generally.]

            SECTION 2. A description of the relative preferences, conversion and
other rights, voting powers, restrictions, limitations as to dividends,
qualifications and terms and conditions of redemption of all series and classes
of series of shares is as 


                                       4
<PAGE>

follows, unless otherwise set forth in Articles Supplementary filed for record
with the State Department of Assessments and Taxation of Maryland or otherwise
determined pursuant to these Articles:

            (a) Assets Belonging to Series. All consideration received or
      receivable by the Corporation for the issue or sale of shares of a
      particular series, together with all assets in which such consideration is
      invested or reinvested, all income, earnings, profits and proceeds
      thereof, including any proceeds derived from the sale, exchange or
      liquidation of such assets, and any funds or payments derived from any
      reinvestment of such proceeds in whatever form the same may be, shall
      irrecovably belong to that series for all purposes, subject only to the
      rights of creditors, and shall be so recorded upon the books of account of
      the Corporation. Such consideration, assets, income, earnings, profits and
      proceeds, including any proceeds derived from the sale, exchange or
      liquidation of such assets, and any funds or payments derived from any
      reinvestment of such proceeds, in whatever form the same may be, together
      with any unallocated items (as hereinafter defined) relating to that
      series as provided in the following sentence, are herein referred to as
      "assets belonging to" that series. In the event that there are any assets,
      income, earnings, profits or proceeds thereof, funds or payments that are
      not readily identifiable as belonging to any particular series
      (collectively "Unallocated Items"), the Board of Directors shall allocate
      such Unallocated Items to and among any one or more of the series created
      from time to time in such manner and on such basis as it, in its sole
      discretion, deems fair and equitable; and any Unallocated Items so
      allocated to a particular series shall belong to that series. Each such
      allocation by the Board of Directors shall be conclusive and binding upon
      the stockholders of all series for all purposes.

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


                                       5
<PAGE>

      manner and on such basis as the Board of Directors in its sole discretion
      deems fair and equitable; and any Unallocated Items so allocated and
      charged to a particular series shall belong to that series. Each such
      allocation by the Board of Directors shall be conclusive and binding upon
      the stockholders of all series for all purposes. To the extent determined
      by the Board of Directors, liabilities and expenses relating solely to a
      particular class (including, without limitation, distribution expenses
      under a Rule 12b-1 plan and administrative expenses under an
      administration or service agreement, plan or other arrangement, however
      designated, which may be adopted for such class) shall be allocated to and
      borne by such class and shall be appropriately reflected (in the manner
      determined by the Board of Directors) in the net asset value, dividends
      and distributions and liquidation rights of the shares of such class.

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

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

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


                                       6
<PAGE>

      1940, as amended from time to time, applicable rules and regulations
      thereunder, or the Maryland General Corporation Law, such requirement as
      to a separate vote of that series or class shall apply in lieu of Single
      Class Voting as described above; (ii) in the event that the separate vote
      requirements referred to in (i) above apply with respect to one or more
      (but less than all) series or classes, then, subject to (iii) below, the
      shares of all other series and classes shall vote as a single class; and
      (iii) as to any matter which does not affect the interest of a particular
      series or class, only the holders of shares of the one or more affected
      series or classes shall be entitled to vote.

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

            SECTION 3. Each share of the capital stock of the Corporation shall
be subject to the following provisions:

            (a) All shares of the capital stock of the Corporation now or
      hereafter authorized shall be subject to redemption and redeemable at the
      option of the stockholder, in the sense used in the General Laws of the
      State of Maryland authorizing the formation of corporations. Each holder
      of the shares of capital stock of the Corporation, upon request to the
      Corporation accompanied by surrender (to the Corporation, or an agent
      designated by it) of the appropriate stock certificate or certificates, if
      any, in proper form for transfer, and such other instruments as the Board
      of Directors may require, shall be entitled to require the Corporation to
      redeem all or any part of the shares of capital stock outstanding in the
      name of such holder on the books of the Corporation, at a redemption price
      equal to the net asset value of such shares determined as hereinafter set
      forth. Notwithstanding the foregoing, the Corporation may deduct from the
      proceeds otherwise due to any stockholder requiring the Corporation to
      redeem shares less a redemption charge not to exceed one percent (1%) of
      such net asset value or a reimbursement charge, a deferred sales charge or
      other charge that is integral to the Corporation's distribution program
      (which charges may vary within and among series and classes) as may be
      established from time to time by the Board of Directors.


                                       7
<PAGE>

            (b) Notwithstanding the foregoing, the Board of Directors of the
      Corporation may suspend the right of the holders of the capital stock of
      the Corporation to require the Corporation to redeem shares of such
      capital stock or may suspend any voluntary purchase of such capital stock:

                  (i) for any period (A) during which the New York Stock
            Exchange is closed other than the customary weekend and holiday
            closing, or (B) during which trading on the New York Stock Exchange
            is restricted;

                  (ii) for any period during which an emergency, as defined by
            the rules of the Securities and Exchange Commission or any successor
            thereto, exists as a result of which (A) disposal by the Corporation
            of securities owned by it is not reasonably practicable, or (B) it
            is not reasonably practicable for the Corporation fairly to
            determine the value of its net assets; or

                  (iii) for such other periods as the Securities and Exchange
            Commission or any successor thereto may by order permit for the
            protection of security holders of the Corporation.


                                       8
<PAGE>

            (c) The Corporation, pursuant to a resolution of the Board of
      Directors and without the vote or consent of stockholders of the
      Corporation, shall have the right to redeem at net asset value all shares
      of capital stock in any stockholder account in which there are less than
      25 shares or such lesser number of shares as shall be specified in such
      resolution. Such resolution shall set forth that redemption of shares in
      such accounts has been determined to be in the economic best interest of
      the Corporation or necessary to reduce disproportionately burdensome
      expenses in servicing stockholder accounts. Such resolution shall provide
      that prior notice of at least 30 days shall be given to a stockholder
      before such redemption of shares and that the stockholder will have 30
      days (or such longer period as is specified in the resolution) from the
      date of the notice to avoid such redemption by increasing his account to
      at least 25 shares, or such lesser number of shares as is specified in the
      resolution.

            SECTION 4. Notwithstanding any provision of Maryland law requiring
any action to be taken or authorized by the affirmative vote of the holders of a
designated proportion greater than a majority of the shares outstanding or of
the votes entitled to be cast, such action shall be effective and valid if taken
or authorized by the affirmative vote of the holders of a majority of the total
number of shares outstanding and entitled to vote thereon pursuant to the
provisions of these Articles of Incorporation.

            SECTION 5. No holder of stock of the Corporation shall, as such
holder, have any right to purchase or subscribe for any shares of the capital
stock of the Corporation which it may issue or sell (whether out of the number
of shares now or hereafter authorized by these Articles of Incorporation, or any
amendment thereof, or out of any shares of the capital stock of the Corporation
acquired by it after the issue thereof, or otherwise) other than such right, if
any, as the Board of Directors, in its discretion, may determine.

                                   ARTICLE VII

            The current number of directors of the Corporation is eight, and the
names of those who shall act as such until their successors are duly elected and
qualify are as follows:

                                Robert S. Dow
                                E. Wayne Nordberg
                                E. Thayer Bigelow


                                       9
<PAGE>

                                Stewart S. Dixon
                                John C. Jansing
                                C. Alan MacDonald
                                Hansel B. Millican
                                Thomas J. Neff

However, the By-Laws of the Corporation may fix the number of directors at a
number other than eight and may authorize the Board of Directors, by the vote of
a majority of the entire Board of Directors, to divide the Board into classes,
to increase or decrease the number of directors within a limit specified in the
By-Laws, provided that in no case shall the number of directors be less than
three, and to fill the vacancies created by any such increase in the number of
directors. Unless otherwise provided in the By-Laws of the Corporation, the
directors of the Corporation need not be stockholders.

                                  ARTICLE VIII

            The following provisions are inserted for the management of the
business and conduct of the affairs of the Corporation, and to create, define,
limit and regulate the powers of the Corporation, the directors and the
stockholders.

            SECTION 1. In furtherance and not in limitation of the powers
conferred by statute and pursuant to these Articles of Incorporation, the Board
of Directors is expressly authorized to do the following:

            (a) To make, adopt, alter, amend and repeal By-Laws of the
      Corporation;

            (b) To distribute, in its discretion, for any fiscal year (in the
      year or in the next fiscal year) as ordinary dividends and as capital
      gains distributions, respectively, amounts sufficient to enable the
      Corporation as a regulated investment company to avoid liability for
      Federal Income tax in respect of such year. Any distribution or dividend
      paid to stockholders from any capital source shall be accompanied by a
      written statement showing the source or sources of such payment;

            (c) To issue and sell or to cause the issuance and sale of shares of
      the Corporation's capital stock in such amounts and on such terms and
      conditions, for 


                                       10
<PAGE>

      such purpose and for such amount or kind of consideration as is now or
      hereafter permitted by the laws of the State of Maryland;

            (d) To purchase and to cause to be purchased shares of the capital
      stock of the Corporation, pursuant to these Articles of Incorporation,
      upon tender thereof by the holder or holders thereof or otherwise,
      provided the Corporation has assets legally available for such purpose
      whether arising out of paid-in surplus, other surplus, net profits or
      otherwise, to such extent and in such manner and upon such terms as the
      Board of Directors shall deem expedient, and to pay for such shares in
      cash then held or owned by the Corporation;

            (e) To authorize, subject to such vote, consent, or approval of
      stockholders and other conditions, if any, as may be required by any
      applicable statute, rule or regulation, the execution and performance by
      the Corporation of an agreement or agreements with any person,
      corporation, association, partnership, or other organization whereby,
      subject to the supervision and control of the Board of Directors, any such
      other person, corporation, association, partnership, or other
      organization, shall render managerial, investment advisory and related
      services to the Corporation (including, if deemed advisable, the
      management or supervision of the investment portfolios of the Corporation)
      upon such terms and conditions as may be provided in such agreement or
      agreements;

            (f) To authorize, subject to such vote, consent or approval of
      stockholders and other conditions, if any, as may be required by any

      the Corporation of an agreement or agreements, which may be exclusive,
      with any person, corporation, association, partnership or other
      organization, as distributor, providing for the sale and distribution of
      shares of the capital stock of the Corporation. Such agreement or
      agreements may provide for the charge by the Corporation of a premium over
      the net asset value (determined as hereinafter provided) of such shares
      and allowance of a discount by the Corporation to such distributor, and
      may further provide for the reallowance by such distributor of concessions
      or commissions from but not exceeding such discount; provided, however,
      that such discount shall not exceed the amount of the premium;

            (g) To authorize any agreement of the character described in
      subsection (e) or (f) of this Section 1 with any person, corporation,
      association, partnership or other organization, although one or more of
      the members of the Board of Directors or officers of the Corporation may
      be the other party to any 


                                       11
<PAGE>

      such agreement or an officer, director, shareholder, or member of such
      other party, and no such agreement shall be invalidated or rendered
      voidable by reason of the existence of any such relationship. Any director
      of the Corporation who is also a director or officer of such corporation
      or who is so interested may be counted in determining the existence of a
      quorum at any meeting of the Board of Directors which shall authorize any
      such agreement, and may vote thereat to authorize any such contract or
      transaction, with like force and effect as if he were not such director or
      officer of such other corporation or not so interested. Any agreement
      entered into pursuant to said subsections (e) or (f) shall be consistent
      with and subject to the requirements of the Investment Company Act of
      1940, as amended from time to time, applicable rules and regulations
      thereunder, or any other applicable Act of Congress hereafter enacted, and
      no amendment to any agreement entered into pursuant to said subsection (e)
      (other than an amendment reducing the compensation of the other party
      thereto) shall be effective unless assented to by the affirmative vote of
      a majority of the outstanding voting securities of the Corporation (as
      such phrase is defined in the Investment Company Act of 1940, as amended
      from time to time) entitled to vote on the matter.

            SECTION 2. The Board of Directors may authorize the purchase by the
Corporation, either directly or through any agent, of shares of its capital
stock, in the open market or otherwise, at prices not in excess of the net asset
value of such shares (determined as hereinafter provided) as of a time
determined by the Board of Directors reasonably proximate to the time of
purchase by the Corporation or any such agent.

            SECTION 3. For the purposes referred to in these Articles of
Incorporation, the net asset value of shares of the capital stock of the
Corporation of each series and class as of any particular time (a "determination
time") shall be determined by or pursuant to the direction of the Board of
Directors as follows:

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


                                       12
<PAGE>

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

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

                  (1) the market value as of any such determination time of any
            security owned by the Corporation which is listed or admitted to
            trading privileges on the New York Stock Exchange or the American
            Stock Exchange shall be the last sale price or (in the case of a
            security in which there has been no previously reported sale
            transaction since the last determination time) the mean between the
            last bid price and the last asked price, for such security on such
            exchange. In case securities being valued are listed or admitted to
            trading privileges on any securities exchange other than the New
            York Stock Exchange, the American Stock Exchange, the securities
            exchange, sale transactions or bid or asked prices which are to be
            used as aforesaid shall be selected by the Board of Directors or any
            officer or other person designated by the Board of Directors for the
            purpose.

                  (2) The market value of securities dealt in in an
            over-the-counter market shall be the mean between the last bid and
            asked price in such market prior to such determination time.

                  (3) The market value of other property, including any
            securities which are neither listed nor admitted to trading
            privileges on any exchange or dealt in an over-the-counter market,
            shall be determined in good faith in such manner as the Board of
            Directors shall prescribe from time to time.


                                       13
<PAGE>

                  (4) The determination of the market value of securities
            hereunder may be made in reliance on any recognized source of
            quotations or basis for ascertaining quotations.

                  (5) If a security is traded in more than one market, a
            determination may be made as to which market most accurately
            reflects the value of such security.

            (b) At times when a series is classified into multiple classes, the
      net asset value of each share of stock of a class of such series shall be
      determined in accordance with subsections (a) and (c) of this Section 3
      with appropriate adjustments to reflect differing allocations of
      liabilities and expenses of such series between or among such classes to
      such extent as may be provided in or determined pursuant to Articles
      Supplementary filed for record with the State Department of Assessments
      and Taxation of Maryland or as may otherwise be determined by the Board of
      Directors.

            (c) The Board of Directors is empowered, in its discretion, to
      establish other methods for determining such net asset value whenever such
      other methods are deemed by it to be necessary or desirable, including,
      but without limiting the generality of the foregoing, any method deemed
      necessary or desirable in order to enable the Corporation to comply with
      any provision of the Investment Company Act of 1940 or any rule or
      regulation thereunder.

            SECTION 4. Any determination as to any of the following matters made
by or pursuant to the direction of the Board of Directors consistent with these
Articles of Incorporation and in the absence of willful misfeasance, bad faith,
gross negligence or reckless disregard of duties, shall be final and conclusive
and shall be binding upon the Corporation and every holder of shares of capital
stock of the Corporation, of any series or class, namely, the amount of the
assets, obligations, liabilities and expenses of the Corporation or belonging to
any series or with respect to any class; the amount of the net income of the
Corporation from dividends and interest for any period and the amount of assets
at any time legally available for the payment of dividends with respect to any
series or class; the amount of paid-in surplus, other surplus, annual or other
net profits, or net assets in excess of capital, undivided profits, or excess of
profits over losses on sales of securities belonging to the Corporation or any
series or class; the amount, purpose, time of creation, increase or decrease,
alteration or cancellation of any reserves or charges and the propriety thereof
(whether or not any obligation or liability for which such reserves or charges
shall have been created shall have been paid or discharged) with respect to the


                                       14
<PAGE>

Corporation or any series or class; the market value, or any sale, bid or asked
price to be applied in determining the market value, of any security owned or
held by the Corporation; the fair value of any other asset owned by the
Corporation; the number of shares of stock of any series or class issued or
issuable; the existence of conditions permitting the postponement of payment of
the repurchase price of shares of stock of any series or class or the suspension
of the right of redemption as provided by law; any matter relating to the
acquisition, holding and disposition of securities and other assets by the
Corporation; any question as to whether any transaction constitutes a purchase
of securities on margin, a short sale of securities, or an underwriting of the
sale of, or participation in any underwriting or selling group in connection
with the public distribution of any securities; and any matter relating to the
issue, sale, repurchase and/or other acquisition or disposition of shares of
stock of any series or class.

            SECTION 5. If the Corporation should change its name and adopt its
corporate title through permission of the firm of Lord, Abbett & Co., which
shall have entered into a management or advisory contract with the Corporation,
the Corporation shall make appropriate agreements that upon the termination of
such contract for any cause, or if such firm or subsidiary or affiliate or
successor deems it advisable to withdraw the right to the use of its name, the
Corporation will, at the request of such firm or a subsidiary, affiliate or
successor, take such action as may be necessary to change its name to eliminate
all use of or reference to the words "Lord Abbett" in any form and will not use
the registered service mark of Lord, Abbett & Co., without the written consent
of such firm, subsidiary, affiliate or successor. The Corporation shall also
agree in such contract that investment companies other than the Corporation for
which such firm or a subsidiary successor may act as investment adviser, and
other companies affiliated with Lord, Abbett & Co., may be formed with the words
"Lord Abbett" in their corporate titles. Such agreements on the part of the
Corporation are hereby made binding upon it, its directors, officers,
stockholders, creditors and all other persons claiming under or through it.

the meeting at his address as the same appears on the books of the  Corporation.

majority  of  such  shares  entitled  to  vote  at the  meeting  so  present  or

of the  Board  there  shall be less than a quorum  present,  a  majority  of the
directors present may adjourn the meeting from time to time until a quorum shall
have been  obtained,  when any business may be transacted  which might have been
transacted  at the meeting as  originally  convened.  No notice of an  adjourned
meeting  of the  directors  other  than an  announcement  of the time and  place
thereof at the preceding meeting shall be required.  The acts of the majority of
the  directors  present at any meeting at which  there is a quorum  shall be the
acts of the Board,  except as  otherwise  provided  by law,  by the  Articles of
Incorporation or by these By-Laws.

Directors  so chosen  shall hold office until their  respective  successors  are
elected and qualify, unless sooner displaced pursuant to law or these By-Laws.
                  The stockholders,  at any meeting called for the purpose, may,
with or  without  cause,  remove any  director  by the  affirmative  vote of the
holders of a  majority  of the votes  entitled  to be cast,  and at any  meeting
called for the purpose may fill the vacancy in the Board thus caused.

Maryland,  as shall be designated in the notice of such meeting.  Notice of each
such meeting shall be mailed to each  director,  at his residence or usual place
of  business,  at least  two days  before  the day of the  meeting,  or shall be
directed to him at such place by  telegraph  or cable,  or be  delivered  to him
personally  not later  than the day before  the day of the  meeting.  Every such
notice  shall  state  the time and place of the  meeting  but need not state the
purposes thereof,  except as otherwise expressly provided in these By-Laws or by
statute.
                  Section 6. Telephonic Conference Meetings.  Any meeting of the
Board or any committee thereof may be held by conference  telephone,  regardless
where each  director  may be located at the time,  by means of which all persons
participating  in the  meeting can hear each other,  and  participation  in such
meeting in such  manner  shall  constitute  presence  in person at such  meeting
except  where the  Investment  Company  Act of 1940,  as  amended,  specifically
requires that the vote of such director be cast in person.
                  Section 7. Fees and Expenses. The directors shall receive such
fees and expenses for services to the  Corporation  as may be fixed by the Board
of Directors,  subject  however,  to such  limitations as may be provided in the

Corporation  shall not in the  absence of fraud be  disqualified  from office by
dealing or contracting  with the  Corporation  either as a vendor,  purchaser or
otherwise,  nor in the absence of fraud shall any transaction or contract of the
Corporation  be void or  voidable  or  affected  by  reason of the fact that any
director,  or any firm of which any director is a member,  or any corporation of
which  any  director  is an  officer,  director  or  stockholder,  is in any way
interested in such transaction or contract;  provided that at the meeting of the
Board of  Directors,  at which said  contract or  transaction  is  authorized or
confirmed, the existence of an interest of such director, firm or corporation is
disclosed  or made  known  and there  shall be  present a quorum of the Board of
Directors a majority of which, consisting of directors not so interested,  shall
approve  such  contract  or  transaction.  Nor shall any  director  be liable to
account to the  Corporation  for any profit  realized by him from or through any
such  transaction  or  contract  of the  Corporation  ratified  or  approved  as
aforesaid, by reason of the fact that he or any firm of which he is a member, or
any  corporation  of which  he is an  officer,  director,  or  stockholder,  was
interested  in such  transaction  or contract.  Directors so  interested  may be
counted when  present at meetings of the Board of  Directors  for the purpose of
determining the existence of a quorum.  Any contract,  transaction or act of the
Corporation or of the Board of Directors (whether or not approved or ratified as
hereinabove provided) which shall be ratified by a majority of the votes cast at
any  annual or  special  meeting  at which a quorum is  present  called for such
purpose,  or approved  in writing by a majority in interest of the  stockholders
having voting power without a meeting,  shall,  except as otherwise  provided by
law,  be valid and as binding as though  ratified  by every  stockholder  of the
Corporation.

resolution  adopted  by a majority  of the whole  Board,  designate  one or more
committees,  each such  committee  to  consist of two or more  directors  of the
Corporation,  which,  to the  extent  permitted  by law  and  provided  in  said
resolution,  shall  have and may  exercise  the  powers  of the  Board  over the
business and affairs of the  Corporation,  and may have power to  authorize  the
seal of the  Corporation  to be affixed to all papers which may require it. Such
committee or committees  shall have such name or names as may be determined from
time to time by resolution adopted by the Board of Directors.  A majority of the
members  of any such  committee  may  determine  its action and fix the time and
place of its meetings,  unless the Board of Directors,  shall otherwise provide.

to fill vacancies in, or to dissolve any such committee.
