Q: WHAT WERE THE OVERALL MARKET CONDITIONS OF THE REPORTING PERIOD?

A: The Federal Reserve Board (the Fed) continued its measured pace of interest
rate hikes, raising the fed funds rate in 0.25% increments in January, March,
May, and June, bringing the rate to 5.25% at the end of the six month period.
The June 29, 2006, interest rate hike marked the seventeenth quarter-point
increase since June 2004. Longer-term rates rose also, with the yield on the
30-year Treasury bond reaching its highest level in nearly two years on higher
energy costs and fears of increasing inflation.

     Despite a weak bond market, high yield and convertible securities managed
to advance. These securities tend to be less sensitive to interest rate
movements than more traditional fixed income investments, and thus were less
affected by the bond market's decline. Convertible and high yield securities do
tend to be more sensitive to economic activity, and these securities benefited
from the continued economic strength and low credit default rates of the past
two quarters.

Q: HOW DID THE FUND PERFORM OVER THE SIX MONTH PERIOD ENDED JUNE 30, 2006?

A: The Fund returned 2.2%, reflecting performance at the net asset value (NAV)
of Class A shares with all distributions reinvested, compared with its
benchmark, the Lehman Brothers U.S. Aggregate Bond Index,1 which returned -0.7%
over the same period. AVERAGE ANNUAL TOTAL


                                                                               1

Q: WHAT WERE THE MOST SIGNIFICANT FACTORS AFFECTING PERFORMANCE?

A: The greatest contributor to performance in the period, relative to the Fund's
benchmark, was the portfolio's holdings of high yield securities. Convertible
securities also added to performance, as did the portfolio's equity holdings.
Both high yield bonds and convertible securities outperformed investment-grade
bonds in the period. Within the investment-grade sector, the portfolio's
holdings in mortgage-backed securities also helped relative performance, as
mortgages outperformed both investment-grade corporate bonds and U.S. Treasury
bonds. Detracting from performance relative to the Fund's benchmark in the high
yield bond sector was the portfolio's underweight position in CCC rated
securities and preference for higher rated securities. Triple Cs outperformed
both BB and B rated securities during the period.

     In the convertible securities sector, drug manufacturer Celgene Corp. made
the greatest individual contribution to performance, followed by Schlumberger
Ltd., an oil field services company; Hanover Compressor, a firm that rents and
repairs compressors for the oil and gas industries; and Apogent Technologies, a
manufacturer of laboratory products for the clinical and industrial markets.
Detracting from performance in the convertible securities sector were Teva
Pharmaceutical Finance, the finance arm of the Israeli-based pharmaceutical
firm; CV Therapeutics, a developer of molecular cardiology products; Openwave
Sytems, a software and services provider to the telecommunications business; and
The Interpublic Group of Companies, an advertising and marketing services firm.

     Contributing to performance in the high yield bond sector were auto
manufacturer General Motors Corp.; Ineos Group Holdings, a diversified chemical
company; and global communications and information services company Level 3
Communications and its financing arm, Level 3 Financing. Detracting from
performance in the high yield bond sector were: Dole Food Co., a major food
processor firm; Chesapeake Energy Corp., an


2

independent explorer and production company focusing on natural gas; Ainsworth
Lumber Co., a producer of lumber, plywood and flooring; and hospital operator
HCA Inc.

     In the investment-grade sector, as mentioned earlier, the portfolio's
holdings in the mortgage-backed securities market contributed to performance
relative to the benchmark. The greatest single contributor to performance in the
investment-grade sector was Airgate PCS Inc., a wireless telecommunications
company. Also adding to performance were Corning Inc., a provider of optical
fiber, cable, and communications network equipment; Alamosa Holdings, a wireless
communications company; and Cummins, Inc., a manufacturer of large diesel
engines. Detracting from performance were gaming company Harrah's; utility
company PG&E Corp.; Freescale Semiconductor, a manufacturer of microchips; and
Wells Fargo & Co., the nation's fifth largest bank.

     The Fund also participates in the equity market. Contributing to
performance in the equity sector were Archer Daniels Midland, a processor of
oilseeds, corn, and wheat; Qwest Communications International, a provider of
long-distance telephone, as well as broadband data, voice, and video services;
BEA Systems, a provider of application server software; and Mentor Graphics
Corp., a provider of electronic design automation software and systems.
Detracting from performance in the equity sector were Comverse Technology, a
manufacturer of communication systems and software; Amgen Inc., a biotech drug
manufacturer; Sun Microsystems, a maker of UNIX-based servers used to power
corporate computer networks and Websites; and utility company TECO Energy, Inc.

     THE FUND'S PORTFOLIO IS ACTIVELY MANAGED AND, THEREFORE, ITS HOLDINGS AND
WEIGHTINGS OF A PARTICULAR ISSUER OR PARTICULAR SECTOR AS A PERCENTAGE OF
PORTFOLIO ASSETS ARE SUBJECT TO CHANGE. SECTORS MAY INCLUDE MANY INDUSTRIES.

NOTE: Class A shares purchased subject to a front-end sales charge have no
contingent deferred sales charge (CDSC). However, certain purchases of Class A
shares made without a front-end sales charge may be subject to a CDSC. Please
see section "Your Investment - Purchases" in the prospectus for more information
on redemptions that may be subject to a CDSC.

EXPENSE EXAMPLE

     As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges on purchase payments (these charges vary among
the share classes); and (2) ongoing costs, including management fees;
distribution and service (12b-1) fees (these charges vary among the share
classes); and other Fund expenses. This Example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.

     The Example is based on an investment of $1,000 invested at the beginning
of the period and held for the entire period (January 1, 2006 through June 30,
2006).

ACTUAL EXPENSES

     For each class of the Fund, the first line of the table on the following
page provides information about actual account values and actual expenses. You
may use the information in this line, together with the amount you invested, to
estimate the expenses that you paid over the period. Simply divide your account
value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6),
then multiply the result by the number in the first line under the heading
entitled "Expenses Paid During the Period 1/1/06 - 6/30/06" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

     For each class of the Fund, the second line of the table on the following
page provides information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio and an assumed rate of return
of 5.0% per year before expenses, which is not the Fund's actual return. The
hypothetical account values and expenses may not be used to estimate the actual
ending account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the Fund and other
funds. To do so, compare this 5.0% hypothetical example with the 5.0%
hypothetical examples that appear in the shareholder reports of the other funds.


                                                                               5

===============================================================================

     Please note that the expenses shown in the table are meant to highlight
your ongoing costs only and do not reflect any transactional costs, such as
sales charges. Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

     ratio for such class (0.99% for Class A, 1.64% for Classes B and C, 1.09%
     for Class P and 0.64% for Class Y) multiplied by the average account value
     over the period, multiplied by 181/365 (to reflect one-half year period).

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1. ORGANIZATION

Lord Abbett Bond-Debenture Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 (the "Act") as a diversified open-end management
investment company. The Fund was incorporated under Maryland law on January 23,
1976.

The Fund's investment objective is to seek high current income and the
opportunity for capital appreciation to produce a high total return. The Fund
offers five classes of shares: Classes A, B, C, P and Y, each with different
expenses and dividends. A front-end sales charge is normally added to the Net
Asset Value ("NAV") for Class A shares. There is no front-end sales charge in
the case of the Classes B, C, P and Y shares, although there may be a contingent
deferred sales charge ("CDSC") as follows: certain redemptions of Class A shares
made within 24 months (12 months if shares were purchased on or after November
1, 2004) following certain purchases made without a sales charge; Class B shares
redeemed before the sixth anniversary of purchase; and Class C shares redeemed
before the first anniversary of purchase. Class B shares will convert to Class A
shares on the eighth anniversary of the original purchase of Class B shares.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
certain estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of increases and decreases in
net assets from operations during the reporting period. Actual results could
differ from those estimates.

2. SIGNIFICANT ACCOUNTING POLICIES

(a)  INVESTMENT VALUATION-Securities traded on any recognized U.S. or non-U.S.
     exchange or on NASDAQ, Inc. are valued at the last sale price or official
     closing price on the exchange or system on which they are principally
     traded. Unlisted equity securities are valued at the last quoted sale price
     or, if no sale price is available, at the mean between the most recently
     quoted bid and asked prices. Fixed income securities are valued at the mean
     between the bid and asked prices on the basis of prices supplied by
     independent pricing services, which reflect broker/dealer supplied
     valuations and electronic data processing techniques. Exchange-traded
     options and futures contracts are valued at the last sale price in the
     market where they are principally traded. If no sale has occurred, the mean
     between the most recently quoted bid and asked prices is used. Securities
     for which market quotations are not readily available are valued at fair
     value as determined by management and approved in good faith by the Board
     of Directors. Short-term securities with 60 days or less remaining to
     maturity are valued using the amortized cost method, which approximates
     current market value.

(b)  SECURITY TRANSACTIONS-Security transactions are recorded as of the date
     that the securities are purchased or sold (trade date). Realized gains and
     losses on sales of portfolio securities are calculated using the
     identified-cost method. Realized and unrealized gains (losses) are
     allocated to each class of shares based upon the relative proportion of net
     assets at the beginning of the day.

(c)  INVESTMENT INCOME-Dividend income is recorded on the ex-dividend date.
     Interest income is recorded on the accrual basis. Discounts are accreted
     and premiums are amortized using the effective interest method. Investment
     income is allocated to each class of shares based upon the relative
     proportion of net assets at the beginning of the day.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED)

(d)  FEDERAL TAXES-It is the policy of the Fund to meet the requirements of
     Subchapter M of the Internal Revenue Code applicable to regulated
     investment companies and to distribute substantially all taxable income and
     capital gains to its shareholders. Therefore, no Federal income tax
     provision is required.

(e)  EXPENSES-Expenses, excluding class specific expenses, are generally
     allocated to each class of shares based upon the relative proportion of net
     assets at the beginning of the day. Classes A, B, C, and P shares bear all
     expenses and fees relating to their respective 12b-1 Distribution Plans.

(f)  FOREIGN TRANSACTIONS-The books and records of the Fund are maintained in
     U.S. dollars and transactions denominated in foreign currencies are
     recorded in the Fund's records at the rate prevailing when earned or
     recorded. Asset and liability accounts that are denominated in foreign
     currencies are adjusted to reflect current exchange rates. The resultant
     exchange gains and losses are included as Net Realized Gain (Loss) on
     Investments and Foreign Currency Related Transactions on the Statement of
     Operations. The Fund does not isolate that portion of the results of
     operations arising as a result of changes in the foreign exchange rates
     from the changes in market prices of the securities.

(g)  FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS-The Fund may enter into forward
     foreign currency exchange contracts in order to reduce its exposure to
     changes in foreign currency exchange rates on its foreign portfolio
     holdings and to lock in the U.S. dollar cost of firm purchase and sale
     commitments for securities denominated in foreign currencies. A forward
     foreign currency exchange contract is a commitment to purchase or sell a
     foreign currency at a future date at a negotiated rate. The contracts are
     valued daily at forward exchange rates and any unrealized gain (loss) is
     included in Net Change in Unrealized Appreciation (Depreciation) on
     Investments and Translation of Assets and Liabilities Denominated in
     Foreign Currencies on the Statement of Operations. The gain (loss) arising
     from the difference between the U.S. dollars cost of the original contract
     and the value of the foreign currency in U.S. dollars upon closing of such
     contracts is included in Net Realized Gain (Loss) on Investments and
     Foreign Currency Related Transactions on the Statement of Operations. As of
     June 30, 2006, there were no open forward foreign currency exchange
     contracts outstanding.

(h)  SECURITIES LENDING-The Fund may lend its securities to member banks of the
     Federal Reserve System and to registered broker/dealers approved by the
     Fund. The loans are collateralized at all times by cash and/or U.S.
     Government securities in an amount at least equal to 102% of the market
     value of domestic securities loaned (105% in the case of foreign securities
     loaned) as determined at the close of business on the preceding business
     day. The dividend and interest income earned on the securities loaned is
     accounted for in the same manner as other dividend and interest income.
     Lending portfolio securities could result in a loss or delay in recovering
     the Fund's securities if the borrower defaults. As of June 30, 2006, the
     value of securities loaned was $678,677,044. These loans are collateralized
     by cash of $689,508,616, which is invested in a restricted money market
     account. State Street Bank & Trust Company ("SSB") received fees of
     $258,559 for the six months ended June 30, 2006, which are netted against
     Securities Lending Income on the Statement of Operations.

(i)  REPURCHASE AGREEMENTS-The Fund may enter into repurchase agreements with
     respect to securities. A repurchase agreement is a transaction in which the
     Fund acquires a security and


                                                                              35

<Page>

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED)

     simultaneously commits to resell that security to the seller (a bank or
     securities dealer) at an agreed-upon price on an agreed-upon date. The Fund
     requires at all times that the repurchase agreement be collateralized by
     cash, or by securities of the U.S. Government, its agencies, its
     instrumentalities, or U.S. Government sponsored enterprises having a value
     equal to, or in excess of, the value of the repurchase agreement (including
     accrued interest). If the seller of the agreement defaults on its
     obligation to repurchase the underlying securities at a time when the value
     of those securities has declined, the Fund may incur a loss upon
     disposition of the securities.

(j)  STRUCTURED SECURITIES-The Fund may invest in structured securities.
     Structured securities are a type of derivative security whose value is
     determined by reference to changes in the value of specific underlying
     securities, currencies, interest rates, commodities, indices, credit
     default swaps, or other indicators (the "Reference"), or to relative
     changes in two or more References. The interest rate or principal amount
     payable upon maturity or redemption may be increased (decreased) depending
     upon changes in the applicable Reference or certain specified events.
     Structured securities may be positively or negatively indexed with the
     result that the appreciation of the Reference may produce an increase
     (decrease) in the interest rate or the value of the security at maturity.

(k)  WHEN-ISSUED OR FORWARD TRANSACTIONS-The Fund may purchase portfolio
     securities on a when-issued or forward basis. When-issued, forward
     transactions or to-be-announced ("TBA") transactions involve a commitment
     by the Fund to purchase securities, with payment and delivery
     ("settlement") to take place in the future, in order to secure what is
     considered to be an advantageous price or yield at the time of entering
     into the transaction. During the period between purchase and settlement,
     the value of the securities will fluctuate and assets consisting of cash
     and/or marketable securities (normally short-term U.S. Government or U.S.
     Government sponsored enterprises securities) marked to market daily in an
     amount sufficient to make payment at settlement will be segregated at a
     Fund's custodian in order to pay for the commitment. At the time the Fund
     makes the commitment to purchase a security on a when-issued basis, it will
     record the transaction and reflect the liability for the purchase and value
     of the security in determining its net asset value. The Fund, generally,
     has the ability to close out a purchase obligation on or before the
     settlement date rather than take delivery of the security. Under no
     circumstances will settlement for such securities take place more than 120
     days after the purchase date.

3. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES

The Fund has a management agreement with Lord, Abbett & Co. LLC ("Lord Abbett")
pursuant to which Lord Abbett supplies the Fund with investment management
services and executive and other personnel, pays the remuneration of officers,
provides office space and pays for ordinary and necessary office and clerical
expenses relating to research and statistical work and supervision of the Fund's
investment portfolio.

The management fee is based on average daily net assets at the following annual
rates:

..50% of the first $500 million of average daily net assets;
..45% of the next $9.5 billion;
..40% over $10 billion.

<Page>

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED)

Lord Abbett provides certain administrative services to the Fund pursuant to an
Administrative Services Agreement at an annual rate of .04% of the Fund's
average daily net assets.

The Fund, along with certain other funds managed by Lord Abbett (the "Underlying
Funds"), have entered into a Servicing Arrangement with Balanced Strategy Fund
of Lord Abbett Investment Trust (the "Fund of Funds"), pursuant to which each
Underlying Fund pays a portion of the expenses (excluding management fees and
distribution and service fees) of the Fund of Funds in proportion to the average
daily value of Underlying Fund shares owned by the Fund of Funds. Amounts paid
pursuant to the Servicing Arrangement are included in Subsidy Expense on the
Statement of Operations.

12b-1 DISTRIBUTION PLAN

The Fund has adopted a distribution plan with respect to one or more classes of
shares pursuant to Rule 12b-1 of the Act, which provides for the payment of
ongoing distribution and service fees to Lord Abbett Distributor LLC
("Distributor"), an affiliate of Lord Abbett. The fees are accrued daily at
annual rates based upon average daily net assets as follows:

<Table>

</Table>

(1)  Annual service fee on shares sold prior to June 1, 1990 is .15% of the
     average daily net asset value.

(2)  The amount of CDSC collected by the Fund for the six months ended June 30,
     2006 was $10,925.

Class Y does not have a distribution plan.

COMMISSIONS

The Distributor received the following commissions on sales of Class A shares of
the Fund, after concessions were paid to authorized dealers, for the six months
ended June 30, 2006:

Distributor received CDSCs of $2,938 and $30,997 for Class A and Class C shares,
respectively, for the six months ended June 30, 2006. One Director and certain
of the Fund's officers have an interest in Lord Abbett.

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARD

Dividends from net investment income, if any, are declared and paid monthly.
Taxable net realized gains from investment transactions, reduced by capital loss
carryforwards, if any, are declared and distributed to shareholders at least
annually. The capital loss carryforward amount, if any, is available to offset
future net capital gains. Dividends and distributions to shareholders are
recorded on the ex-dividend date. The amount of dividends and distributions from
net investment income and net realized capital gains are determined in
accordance with Federal income tax regulations which may differ from accounting
principles generally accepted in the United States of America. These book/tax
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the components of net assets based on their federal tax basis treatment;
temporary differences do not require reclassification. Dividends and
distributions, which exceed earnings and profits for tax purposes, are reported
as a tax return of capital.


                                                                              37

6. DIRECTORS' REMUNERATION

The Fund's officers and the one Director who are associated with Lord Abbett do
not receive any compensation from the Fund for serving in such capacities.
Outside Directors fees are allocated among all Lord Abbett-sponsored funds based
on the net assets of each fund. There is an equity based plan available to all
outside Directors under which outside Directors must defer receipt of a portion
of, and may elect to defer receipt of an additional portion of Directors' fees.
The deferred amounts are treated as though equivalent dollar amounts have been
invested proportionately in the funds. Such amounts and earnings accrued thereon
are included in Directors' Fees on the Statement of Operations and in Directors'
Fees Payable on the Statement of Assets and Liabilities and are not deductible
for U.S. Federal income tax purposes until such amounts are paid.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED)

7. EXPENSE REDUCTIONS

The Fund has entered into arrangements with its transfer agent and custodian
whereby credits realized as a result of uninvested cash balances are used to
reduce a portion of the Fund's expenses.

8. LINE OF CREDIT

The Fund, along with certain other funds managed by Lord Abbett, have available
a $250,000,000 unsecured revolving credit facility ("Facility") from a
consortium of banks, to be used for temporary or emergency purposes as an
additional source of liquidity to fund redemptions of investor shares. Any
borrowings under this Facility will bear interest at current market rates as
defined in the agreement. The fee for this Facility is an annual rate of .08%.
As of June 30, 2006, there were no loans outstanding pursuant to this Facility
nor was the Facility utilized at any time during the six months ended June 30,
2006.

9. CUSTODIAN AND ACCOUNTING AGENT

SSB is the Fund's custodian and accounting agent. SSB performs custodial,
accounting and recordkeeping functions relating to portfolio transactions and
calculating the Fund's NAV.

10. INVESTMENT RISKS

The Fund is subject to the general risks and considerations associated with
investing in debt securities. The value of an investment will change as interest
rates fluctuate and in response to market movements. When interest rates rise,
the prices of debt securities are likely to decline; when rates fall, such
prices tend to rise. Longer-term securities are usually more sensitive to
interest rate changes. There is also the risk that an issuer of a debt security
will fail to make timely payments of principal or interest to the Fund, a risk
that is greater with high yield securities (sometimes called "lower-rated debt
securities" or "junk bonds") in which the Fund may invest. Some issuers,
particularly of high yield securities, may default as to principal and/or
interest payments after the Fund purchases its securities. A default, or
concerns in the market about an increase in risk of default, may result in
losses to the Fund. High yield bonds are subject to greater price fluctuations,
as well as additional risks.

The mortgage-related securities in which the Fund may invest may be particularly
sensitive to changes in prevailing interest rates. When interest rates are
declining, the value of these securities with prepayment features may not
increase as much as other fixed income securities. Early principal repayment may
deprive the Fund of income payments above current market rates. The prepayment
rate also will affect the price and volatility of a mortgage-related security.
Some of these securities may be those of such Government sponsored enterprises
as Federal Home Loan Mortgage Corporation and Federal National Mortgage
Association. Such securities are guaranteed with respect to the timely payment
of interest and principal by the particular Government sponsored enterprise
involved, not by the U.S. Government.

The Fund may invest up to 5% of its net assets in structured securities. The
Fund typically may use these securities as a substitute for taking a position in
the underlying asset and/or as part of a strategy designed to reduce exposure to
other risk, such as interest rate or currency risk. Structured securities may
present additional risks that are different from those associated with a direct
investment in fixed-income or equity securities; they may be volatile, less
liquid and


                                                                              39

<Page>

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONTINUED)

more difficult to price accurately and subject to additional credit risks.
Changes in the value of structured securities may not correlate perfectly with
the underlying asset, rate or index. The Fund that invests in structured
securities could lose more than the principal amount invested.

The Fund may invest up to 20% of its net assets in equity securities which may
subject it to the general risks and considerations associated with investing in
equity securities. The value of an investment will fluctuate in response to
movements in the stock market in general and to the changing prospects of
individual companies in which the Fund invests.

The Fund may invest up to 20% of its net assets in foreign securities which may
present market liquidity, currency, political, information, and other risks.

These factors can affect the Fund's performance.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)(CONCLUDED)

12. RECENT ACCOUNTING PRONOUNCEMENT

In July 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation 48, Accounting for Uncertainty in Income Taxes - an
interpretation of FASB Statement 109 (FIN 48). FIN 48 clarifies the accounting
for income taxes by prescribing the minimum recognition threshold a tax position
must meet before being recognized in the financial statements. FIN 48 is
effective for fiscal years beginning after December 15, 2006. The Fund will
adopt FIN 48 during 2007 and the impact to the Fund's financial statements, if
any, is currently being assessed.


                                                                              41

HOUSEHOLDING

The Fund has adopted a policy that allows it to send only one copy of the Fund's

want your mailings to be "householded," please call Lord Abbett at 800-821-5129
or send a written request with your name, the name of your fund or funds, and

          At the June 22, 2006 meetings of the Nominating and Governance
          Committees (the "Committee") of the Boards of each of the Lord Abbett
          Funds, the Committee adopted policies and procedures for the
          nomination of independent directors/trustees ("Procedures"). The
          Procedures provide criteria for the nomination of independent
          directors/trustees, as well as a process for identifying and
          evaluating candidates. With respect to shareholder recommendations, it
          is the Committee's policy to consider director/trustee nominations
          recommended by shareholders using the same criteria the Committee uses
          in considering potential director/trustee nominations from other
          sources. The Committee believes that directors/trustees must represent
          all shareholders and not just a limited set of shareholders. A copy of
          the Procedures may be found at www.LordAbbett.com.
