Q: WHAT WERE THE OVERALL MARKET CONDITIONS OF THE SIX-MONTH PERIOD ENDED JANUARY
31, 2006?

A: During the period, a few major trends dominated the equity markets. Perhaps
most influential was the building strength of equities, especially during the
latter half of the period, as the U.S. economy proved resilient.

   Across the indexes tracked by Standard & Poor's, equities with a value bias
outperformed growth stocks. However, strip away the dominance of
large-capitalization stocks in market-weighted aggregate indexes - and the
picture changes. In style-box fashion, mid-capitalization growth stocks led
small growth equities, which in turn outperformed large value stocks. Although
large value equities outperformed their growth-oriented peers during the period,
large-cap growth gained substantial momentum in the broad rally experienced in
November 2005 and January 2006.

   In the broad S&P Super Composite 1500(R) Index,(1) the top performing sectors
during the period included energy, materials, and financials, while the
underperforming sectors were consumer discretionary, telecommunications, and
consumer staples.

Q: HOW DID THE FUND PERFORM OVER THE SIX-MONTH PERIOD ENDED JANUARY 31, 2006?

A: The fund returned 10.3 percent, reflecting performance at the net asset value
(NAV) of Class A shares, with all distributions reinvested, compared with its
benchmark, the Russell 2000(R) Index,(2) which returned 8.5 percent over the
same period. STANDARDIZED AVERAGE ANNUAL TOTAL RETURNS, WHICH REFLECT
PERFORMANCE AT THE MAXIMUM 5.75 PERCENT SALES CHARGE APPLICABLE TO CLASS A SHARE
INVESTMENTS AND INCLUDE THE REINVESTMENT OF ALL DISTRIBUTIONS, AS OF JANUARY 31,
2006, ARE: 1 YEAR: 13.47 PERCENT AND SINCE INCEPTION (JUNE 26, 2001): 15.35
PERCENT. Class A shares purchased subject to a

                                                                               1

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.

Q: WHAT WERE THE MOST SIGNIFICANT FACTORS AFFECTING PERFORMANCE OVER THE
SIX-MONTH PERIOD ENDED JANUARY 31, 2006?

CONTRIBUTING TO FUND PERFORMANCE

A: The materials and processing sector was the strongest contributor to
performance, relative to the fund's benchmark, followed by the financial
services sector and the fund's underweight position in the utilities sector.

   Strong performing materials and processing holdings included Hughes Supply,
Inc., a wholesale distributor of construction, repair, and maintenance-related
products, and Commercial Metals Co., a provider of steel and metal products and
related materials. Other materials and processing companies, Cleveland-Cliffs
Inc., an iron ore pellets producer, and Watsco, Inc., a distributor of air
conditioning, heating, and refrigeration equipment, related parts and supplies,
also performed well during the period.

   Although the financial services sector ranked second in terms of sector
contribution to performance, relative to the fund's benchmark, none of the
fund's financial services holdings were among the top 10 contributors to
performance. However, three of the fund's top 10 largest holdings were financial
services companies. In addition, the fund's lack of exposure to the utilities
sector, relative to its benchmark, proved to be a positive factor.

   Select Comfort Corp., a consumer discretionary holding that provides a line
of airbed mattresses with adjustable firmness, as well as foundations and
accessories, was a solid contributor to performance and the fourth largest
holding for the period. Additional holdings

<Page>

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

that performed well included Pride International, Inc., a company listed in the
other energy sector. Pride International provides contract drilling and related
services on land and offshore. It was the fund's largest holding and the
strongest contributor to performance.

   Two healthcare stocks were also among the top 10 contributors to performance:
LCA-Vision Inc., which develops and operates stand-alone laser vision correction
centers, and Par Pharmaceutical Cos. Inc., which manufactures and distributes
generic drugs. In addition, producer durables company, Actuant Corp., a maker of
a broad range of industrial products and systems, and technology holding
Websense, Inc., a provider of employee Internet management solutions, each
helped fund performance. Websense was the fund's tenth largest holding for the
period.

DETRACTING FROM FUND PERFORMANCE

   The worst performing sector for the fund, relative to the fund's benchmark,
during the period was technology. Stratasys, Inc., a maker of rapid prototyping
systems, and Hutchinson Technology Inc., a supplier of suspension assemblies for
hard disk drives, took away from fund performance.

   The consumer discretionary and the producer durables sectors detracted
equally from performance relative to the fund's benchmark. Tuesday Morning
Corp., a closeout retailer of upscale home furnishings, gifts, and related
items, was the weakest performing holding for the period. Other consumer
discretionary holdings that hurt fund performance included Entravision
Communications Corp., a diversified media company; Regent Communications, Inc.,
a radio broadcasting company; SM&A, a provider of competition management
services; and Dave & Buster's, Inc., an operator of restaurant entertainment
complexes. Producer durables holding, The Ryland Group, Inc., a homebuilder and
mortgage-related finance firm, was the fund's second largest holding for the
period, and a detractor from fund performance.

   Other stocks that disappointed were healthcare company Kensey Nash Corp. and
Massey Energy Co., categorized in the other energy sector. Kensey makes a line
of absorbable medical devices. Massey produces, processes, and sells bituminous,
low sulphur coal of steam and metallurgical grades through its processing and
shipping centers. Massey was the fund's fifth largest holding.

   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.

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 (August 1, 2005 through January 31,
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 8/1/05 - 1/31/06" 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% 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% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

                                                                               5
<Page>

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

   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.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.   ORGANIZATION

Lord Abbett Blend Trust (the "Trust") is registered under the Investment Company
Act of 1940 (the "Act") as an open-end management company, organized as a
Delaware Business Trust on May 1, 2001. The Trust has one series, Lord Abbett
Small-Cap Blend Fund (the "Fund"). The Securities and Exchange Commission
declared the registration of the Fund and its shares effective on June 26, 2001
and each class of shares became available to the public on July 2, 2001. The
Fund is diversified under the Act.

The Fund's investment objective is to seek long-term growth of capital by
investing primarily in stocks of small companies. 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. 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 Trustees. 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 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)  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 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.

3.   MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEE
The Trust 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,

expenses relating to research and statistical work and supervision of the Fund's
investment portfolio.

The management fee is based on the following annual rates:

     .75% of the first $1 billion of average daily net assets;
     .70% over $1 billion.

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.

12b-1 DISTRIBUTION PLANS
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

</Table>

(1)  Until October 1, 2004, the Fund paid a one-time distribution fee of up to
     1.00% on certain qualifying purchases of Class A shares. Effective October
     1, 2004, the Distributor commenced payment of such one-time distribution
     fee. The unamortized balance of the prepaid distribution fees as of January
     31, 2006 was $19,851. This amount will continue to be amortized by the
     Fund, generally over a two-year period.

(2)  The amount of CDSC collected during the six months ended January 31, 2006
     was $872.

                                                                              19

4.   DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARD

Dividends from net investment income, if any, are declared and paid at least
annually. 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.

The tax character of distributions paid during the six months ended January 31,
2006 and the fiscal year ended July 31, 2005 are as follows:

The Trust's officers and the one Trustee who are associated with Lord Abbett do
not receive any compensation from the Trust for serving in such capacities.
Outside Trustees' 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 Trustees under which outside Trustees must defer receipt of a portion
of, and may elect to defer receipt of an additional portion of Trustees' 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 Trustees' Fees on the Statement of Operations and in Trustees'
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.

7.   EXPENSE REDUCTIONS

The Fund has entered into arrangements with its transfer agent and custodian

The Fund, along with certain other funds managed by Lord Abbett, has 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. Effective December 9, 2005,
the amount available to the funds under the Facility was increased from
$200,000,000 to 250,000,000. Any borrowings under this Facility will bear
interest at current market rates as defined in the agreement. The fee for this
Facility is at an annual rate of .08%. At January 31, 2006, there were no loans
outstanding pursuant to this Facility nor was the Facility utilized at any time
during the six months ended January 31, 2006.

11.  INVESTMENT RISKS

The Fund is subject to the general risks and considerations associated with
equity investing as well as the particular risks associated with growth and
value stocks. 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. Different types of stocks shift in and out
of favor depending on market and economic conditions. Growth stocks tend to be
more volatile than other stocks. The market may fail to recognize the intrinsic
value of particular value stocks for a long time. In addition, if the Fund's
assessment of a company's potential for growth or market conditions is wrong, it
could suffer losses or produce poor performance relative to other funds, even in
a rising market. The Fund invests primarily in small company stocks, which tend
to be more volatile and can be less liquid than large company stocks. Small
companies may also have more limited product lines, markets or financial
resources, and typically experience a higher risk of failure than large
companies.

These factors can affect the Fund's performance.

13.  SUBSEQUENT EVENT

As of the close of business on January 31, 2006, Class A, B, C, P, and Y shares
of the Fund are not available for purchase by new investors other than through
certain retirement and benefit plans, and financial intermediaries that provide
recordkeeping or advisory services and have entered into special arrangements
with the Fund or the Distributor. In addition, Directors/Trustees of the Lord
Abbett Family of Funds, partners and employees of Lord Abbett, and the family
members of such persons may purchase shares of the Fund. Investors should note,
however, that the Fund reserves the right to refuse any order that might disrupt
the efficient management of the Fund.

                                                                              23

APPROVAL OF ADVISORY CONTRACTS

At meetings on December 7 and 8, 2005, the Board, including all Trustees who are
not interested persons, considered whether to approve the continuation of the
existing management agreement between the Fund and Lord Abbett. In addition to
the materials the Board had reviewed throughout the course of the year, the
Board received materials relating to the management agreement before the meeting
and had the opportunity to ask questions and request further information in
connection with its consideration. The Board also took into account its
familiarity with Lord Abbett gained through its previous meetings and
discussions, and the examination of the portfolio management team conducted by
members of the Contract Committee during the year.

The materials received by the Board included, but were not limited to, (1)
information provided by Lipper Analytical Services, Inc. regarding the
investment performance of the Fund compared to the investment performance of a
group of funds with substantially similar investment objectives (the
"performance universe") and to the investment performance of an appropriate
securities index (if such an index existed), for various time periods each
ending September 30, 2005, (2) information on the effective management fee rates
and expense ratios for funds with similar objectives and similar size (the "peer
group"), (3) sales and redemption information for the Fund, (4) information
regarding Lord Abbett's financial condition, (5) an analysis of the relative
profitability of the management agreement to Lord Abbett, (6) information
regarding the distribution arrangements of the Fund, (7) information regarding
the personnel and other resources devoted by Lord Abbett to managing the Fund.

INVESTMENT MANAGEMENT SERVICES GENERALLY. The Board considered the investment
management services provided by Lord Abbett to the Fund, including investment
research, portfolio management, and trading, and Lord Abbett's commitment to
compliance with all relevant legal requirements. The Board also observed that
Lord Abbett was solely engaged in the investment management business and
accordingly did not experience the conflicts of interest resulting from being
engaged in other lines of business. The Board noted that Lord Abbett did not use
brokerage commissions to purchase third-party research. The Board also
considered the investment advisory services provided by Lord Abbett to other
clients, the fees charged for the services, and the differences in the nature of
the services provided to the Fund and other Lord Abbett Funds, on the one hand,
and the services provided to other clients, on the other.

INVESTMENT PERFORMANCE AND COMPLIANCE. The Board reviewed the Fund's investment
performance as well as the performance of the performance universe of funds,
both in terms of total return and in terms of other statistical measures. The
Board observed that the Fund's performance of the Class A shares of the Fund was
in the first quintile of its performance universe for the nine-month and
three-year periods and in the second quintile in the one-year period. The Board
also observed that the performance was above that of the Lipper Small-Cap Core
Index for each period.

LORD ABBETT'S PERSONNEL AND METHODS. The Board considered the qualifications of
the personnel providing investment management services to the Fund, in light of
its investment objective and discipline. Among other things, they considered the
size, experience, and turnover rates of Lord Abbett's investment management
staff, Lord Abbett's investment methodology and philosophy, and Lord Abbett's
approach to recruiting, training, and retaining investment management personnel.
The Board determined that Lord Abbett had the expertise and resources to manage
the Fund effectively.

<Page>

NATURE AND QUALITY OF OTHER SERVICES. The Board considered the nature, quality,
costs, and extent of administrative and other services performed by Lord Abbett
and Lord Abbett Distributor and the nature and extent of Lord Abbett supervision
of third party service providers, including the Fund's transfer agent and
custodian.

EXPENSES. The Board considered the expense ratio of the Fund and the expense
ratios of peer groups. It also considered the amount and nature of the fees paid
by shareholders. The Board observed that the contractual and actual management
and administrative services fees were approximately the same as the median of
the peer group. The Board also observed that the total expense ratio of Class A
was approximately nine basis points above the median of the peer group, the
total expense ratios of Classes B and C were approximately five basis points
below the median of the peer group, the total expense ratio of Class P was
approximately thirteen basis points above the median of the peer group, and the
total expense ratio of Class Y was approximately seven basis points above the
median of the peer group.

PROFITABILITY. The Board considered the level of Lord Abbett's profits in
managing the Fund, including a review of Lord Abbett's methodology for
allocating its costs to its management of the Fund. The Board concluded that the
allocation methodology had a reasonable basis and was appropriate. It considered
the profits realized by Lord Abbett in connection with the operation of the Fund
and whether the amount of profit was fair for the management of the Fund. The
Board also considered the profits realized from other businesses of Lord Abbett,
which may benefit from or be related to the Fund's business. The Board
considered Lord Abbett's profit margins in comparison with available industry
data, both accounting for and ignoring marketing and distribution expenses, and
how those profit margins could affect Lord Abbett's ability to recruit and
retain investment personnel. The Board recognized that Lord Abbett's
profitability was a factor in enabling it to attract and retain qualified
investment management personnel to provide services to the Fund. The Board noted
that Lord Abbett's profitability had increased, in part due to an increase in
assets under management, but concluded that Lord Abbett's profitability overall
and with respect to the Fund was not excessive.

ECONOMIES OF SCALE. The Board considered whether there had been any economies of
scale in managing the Fund, whether the Fund had appropriately benefited from
any such economies of scale, and whether there was potential for realization of
any further economies of scale. The Board concluded that the existing advisory
fee schedule adequately addressed any economies of scale in managing the Fund.

OTHER BENEFITS TO LORD ABBETT. The Board considered the character and amount of
fees paid by the Fund and the Fund's shareholders to Lord Abbett and Lord Abbett
Distributor for services other than investment advisory services. The Board also
considered the revenues and profitability of Lord Abbett's investment advisory
business apart from its mutual fund business, and the intangible benefits
enjoyed by Lord Abbett by virtue of its relationship with the Fund. The Board
observed that Lord Abbett Distributor receives 12b-1 fees from the Fund as to
shares held in accounts for which there is no other broker of record, may retain
a portion of the 12b-1 fees from the Fund, and receives a portion of the sales
charges on sales and redemptions of some classes of shares. In addition, Lord
Abbett accrues certain benefits for its business of providing investment advice
to clients other than the Fund, but that that business also benefits the Fund.
The Board also noted that Lord Abbett, as disclosed in the prospectus of the
Fund, has entered into revenue sharing arrangements with certain entities that
distribute shares of the Fund.

                                                                              25
<Page>

ALTERNATIVE ARRANGEMENTS. The Board considered whether, instead of approving
continuation of the management agreement, employing one or more alternative
arrangements might be in the best interests of the Fund, such as continuing to
employ Lord Abbett, but on different terms.

In considering whether to approve the continuation of the management agreement,
the Board did not identify any single factor as paramount or controlling. This
summary does not discuss in detail all matters considered. After considering all
of the relevant factors, the Board unanimously found that continuation of the
existing management agreement was in the best interests of the Fund and its
shareholders and voted unanimously to approve the continuation of the management
agreement.
