                                  OUR COMPANY

    We are a holding company that is the sole member of LaBranche & Co. LLC and
owns all the outstanding stock of LaBranche Financial Services, Inc. Founded in
1924, our principal operating subsidiary, LaBranche & Co. LLC, is one of the
oldest and largest specialist firms on the NYSE. We also act as a specialist in
stocks and options on the AMEX. As a specialist, our role is to maintain, as far
as practicable, a fair and orderly market in our specialist stocks. In doing so,
we provide a service to our listed companies, and to the brokers, traders and
their respective customers who trade in our specialist stocks. We believe that,
as a result of our commitment to providing high quality specialist services, we
have developed a strong reputation among our constituencies, including
investors, members of the Wall Street community and our listed companies.

    Our LaBranche Financial Services, Inc. subsidiary is a clearing broker for
customers of introducing brokers, provides direct access floor brokerage
services to institutional customers, provides securities clearing and other
related services to individual and institutional clients, including traders,
professional investors and broker-dealers, and provides front-end order
execution, analysis and reporting solutions for the wholesale securities dealer
market.

    Our business has grown considerably during the past five years. Our revenues
have increased from approximately $49.9 million in 1996 to $424.1 million in
2001, representing a compound annual growth rate of 53.4%. We have accomplished
our growth both internally and through acquisitions. For example, since the NYSE
implemented the current specialist allocation process in March 1997, we have
been selected by 87 new listed companies, resulting from 178 listing interviews.
In addition, we have acquired ten specialist operations since 1997, adding over
550 NYSE and AMEX common stocks and 107 AMEX-listed options for which we act as
the specialist. During the past five years, we also have increased the scope of
our business, as illustrated by the following data, much of which has been
obtained from the NYSE:

    - the annual dollar volume on the NYSE of stocks for which we acted as
      specialist increased to $2.5 trillion in 2001, from $201.4 billion in
      1996. Based on these dollar volumes, we were the largest NYSE specialist
      firm in 2001 as compared to the sixth largest in 1996;

    - the annual share volume on the NYSE of stocks for which we act as
      specialist increased to 76.0 billion in 2001, from 5.6 billion in 1996.
      Based on these share volumes, we were the largest NYSE specialist firm in
      2001 as compared to the fourth largest in 1996; and

    - the total number of our NYSE common stock listings increased to 591 as of
      December 31, 2001, from 132 as of December 31, 1996. Based on the number
      of our NYSE common stock listings, we were the largest NYSE specialist
      firm as of December 31, 2001 as compared to the fourth largest as of
      December 31, 1996. In addition, we act as the specialist for 266 other
      NYSE-listed securities (e.g., preferred and convertible securities) and
      for 57 stocks and 122 options on the AMEX.

                                       1

    As of December 31, 2001, our listed companies included:

    - 104 of the S&P 500 Index companies; and

    - nine of the 30 companies comprising the Dow Jones Industrial Average.
      These listed companies are American Express Company, AT&T, DuPont, Eastman
      Kodak, Exxon Mobil, Merck, Minnesota Mining & Manufacturing, Philip Morris
      and SBC Communications.

THE NYSE SPECIALIST

    All trading of securities on the NYSE is conducted through an auction
process. The auction process for each security is managed by the specialist for
that security. The specialist is a broker-dealer who applies for and, if
accepted, is assigned the role to maintain a fair and orderly market in its
specialist stocks. The number of specialist units on the NYSE has decreased from
37 at December 31, 1996 to nine at December 31, 2001. A recently announced
transaction, if consummated, would further reduce the number of specialist units
on the NYSE to eight. Of the nine specialist units, the three largest specialist
units as ranked by their number of specialist stocks were responsible for
approximately 56.0% and 69.6% of dollar trading volume in 2000 and 2001,
respectively.


    An NYSE specialist firm is granted the franchise by the NYSE to conduct the
auction in each security listed on the NYSE. NYSE specialist firms conduct their
auctions at specific trading posts located on the floor of the exchange. Because
the specialist firm runs the auction in its specialist stocks, it knows of all
bids and offers in those stocks and gathers orders to price its stocks
appropriately.


OUR COMPETITIVE POSITION

    We are committed to providing the highest quality service to our various
constituencies. We believe our success is based on the following factors:

    - our leading position in the specialist market;

    - our diverse and high-quality specialist stocks;

    - our strong market-making skills;

    - our innovative customer-oriented services; and

    - our ability to successfully integrate the companies we have acquired.

RISK MANAGEMENT

    Because our specialist activities expose our capital to significant risks,
managing these risks is a constant priority for us. Our central role in the
auction process helps us to reduce risks by enabling us to incorporate
up-to-date market information in the management of our inventory, subject to our
specialist obligations. In addition, we have developed a risk management process
which is designed to balance our ability to profit from our specialist
activities with our exposure to potential losses. Our risk management process
includes participation from our executive operating committee, our floor
management committee, our floor team captains and our specialists.

AMEX SPECIALIST ACTIVITIES

    In December 2000, we purchased the assets and operations of an AMEX options
specialist unit and run this business through our LaBranche & Co. LLC
subsidiary. In August 2001, we expanded our AMEX specialist activities by
purchasing the assets and operations of another AMEX specialist firm, Cranmer &
Cranmer, Inc. These transactions enhance our commitment to the listed auction
market

                                       2

and are important steps in the implementation of our growth and diversification
strategy. Our AMEX specialist unit acts as the specialist in 57 stocks and 122
options.

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

    Our executive offices are located at One Exchange Plaza, New York, New York

                SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA

    Our summary historical consolidated financial data set forth below for each
year in the five-year period ended December 31, 2000 have been derived from our
consolidated financial statements, which have been audited by Arthur Andersen
LLP, independent public accountants. The summary historical consolidated
financial data for the nine months ended September 30, 2001 and 2000 were
derived from our unaudited consolidated financial statements. Management
believes the unaudited historical consolidated financial statements contain all
adjustments needed to present fairly the information contained in those
statements, and the adjustments made consist only of normal recurring
adjustments. The results of operations for the nine month period ended
September 30, 2001 are not necessarily indicative of the results of operations
for the full year. You should read our summary historical consolidated financial
data set forth below in conjunction with the consolidated financial statements
and related notes and the section entitled "Management's Discussion and Analysis
of Financial Condition and Results of Operations" in each of our Form 10-K for
the year ended December 31, 2000 and our Forms 10-Q for the quarterly periods
ended March 31, June 30 and September 30, 2001, each of which is incorporated in
this prospectus by reference.

                                  RISK FACTORS

    BEFORE INVESTING IN OUR COMMON STOCK, YOU SHOULD CAREFULLY CONSIDER THE
RISKS DESCRIBED BELOW AND THE OTHER INFORMATION INCLUDED IN THIS PROSPECTUS AND
IN THE DOCUMENTS INCORPORATED IN THIS PROSPECTUS BY REFERENCE.

OUR REVENUES MAY DECREASE DUE TO CHANGES AFFECTING THE ECONOMY, SUCH AS
INCREASES IN INTEREST RATES OR INFLATION, OR CHANGES AFFECTING THE SECURITIES
MARKETS, SUCH AS DECREASED VOLUME OR LIQUIDITY.

    An adverse change affecting the economy or the securities markets could
result in a decline in market volume or liquidity. This would result in lower
revenues from our specialist and other activities. Historically, increases in
our revenues have resulted primarily from significant increases in the volume of
trading on the NYSE and favorable conditions in the securities markets. More
recently, however, the economy has begun to slow and financial markets have
become less prosperous in comparison to the past several years. If this causes a
decline in market volume, or if market liquidity becomes compromised, our
revenues could decline and our results of operations could be adversely
affected.

OUR RESULTS MAY FLUCTUATE SIGNIFICANTLY.

    Our revenues may fluctuate significantly based on factors relating to the
securities markets. These factors include:

    - a decrease in trading volume on the NYSE and the AMEX;

    - volatility in the equity securities markets; and

    - changes in the value of our securities positions.

    Many elements of our cost structure do not decline if we experience
reductions in our revenues. As a result, if market conditions cause our revenues
to decline, we may be unable to adjust our cost structure on a timely basis and
we could suffer losses.

SUSTAINED DECLINES IN PRICE LEVELS OF SECURITIES COULD CAUSE US TO INCUR LOSSES.

    Adverse changes in the economy and the securities markets could lead to
lower price levels of securities. Sustained declines in these price levels may
result in:

    - losses from declines in the market value of securities held in our
      accounts;

    - the failure of buyers and sellers of securities to fulfill their
      settlement obligations; and

    - increases in claims and litigation.

RISKS ASSOCIATED WITH OUR TRADING TRANSACTIONS COULD RESULT IN TRADING LOSSES.

    A majority of our specialist-related revenues are derived from trading by us
as principal. We may incur trading losses relating to these activities since
each such trade primarily involves the purchase, sale or short sale of
securities for our own account. In any period, we may incur trading losses in a
significant number of our specialist stocks for a variety of reasons, including
price declines of our specialist stocks, lack of trading volume in our
specialist stocks and the required performance of our specialist obligations.
From time to time, we have large position concentrations in securities of a
single issuer or issuers engaged in a specific industry. In general, because our
inventory of securities is marked to market on a daily basis, any downward price
movement in these securities will result in a reduction of our revenues and
operating profits. We also operate a proprietary trading desk separately from
our specialist operations, which represented 0.5% of our total revenues in 2000
and 0.3% of our total revenues in 2001. We may incur trading losses as a result
of these trading activities.

                                       7

    Although we have adopted risk management policies, we cannot be sure that
these policies have been formulated properly to identify or completely limit our
risks. Even if these policies are formulated properly, we cannot be sure that we
will successfully implement these policies. As a result, we may not be able to
manage our risks successfully or avoid trading losses.

SPECIALIST RULES MAY REQUIRE US TO MAKE UNPROFITABLE TRADES OR TO REFRAIN FROM
MAKING PROFITABLE TRADES.

    When we trade as principal, we attempt to derive a profit from the
difference between the prices at which we buy and sell securities. Our role as a
specialist, at times, requires us to make trades that adversely affect our
profitability. In addition, as a specialist, we are at times required to refrain
from trading for our own account in circumstances in which it may be to our
advantage to trade. For example, we may be obligated to act as a principal when
buyers or sellers outnumber each other. In those instances, we may take a
position counter to the market, buying or selling shares to support an orderly
market in the affected stocks. In order to perform these obligations, we hold
varying amounts of securities in inventory. In addition, specialists generally
may not trade for their own account when public buyers are meeting public
sellers in an orderly fashion and may not compete with public orders at the same
price. By having to support an orderly market, maintain inventory positions and
refrain from trading under some favorable conditions, we are subject to risk.
Additionally, the NYSE and the AMEX periodically amend their rules and may make
the rules governing our activities as a specialist more stringent or may
implement changes which could adversely affect our trading revenues.

WE DEPEND SIGNIFICANTLY ON REVENUES FROM OUR NYSE SPECIALIST ACTIVITIES WITH
RESPECT TO A SMALL GROUP OF LISTED COMPANIES, AND THE LOSS OF ANY OF THEM COULD
REDUCE OUR REVENUES.


    Historically, a relatively small number of listed companies have accounted
for a significant portion of our revenues from our NYSE specialist trading
activities. The loss of any of these listed companies could have an adverse
effect on our revenues. For the years ended December 31, 1999, 2000 and 2001,
transactions in our 10 most actively traded NYSE specialist stocks accounted for
approximately 44.2%, 38.7% and 28.2% of our total principal revenues,
respectively. We cannot assure you that we will be able to retain these or other
listed companies. We can lose these listed companies if they cease to be traded
on the NYSE as a result of being acquired or otherwise delisted. In addition, if
the NYSE were to determine that we have failed to fulfill our obligations as
specialist for a listed company, our registration as the specialist for that
listed company could be canceled or suspended.


WE DEPEND PRIMARILY ON OUR SPECIALIST ACTIVITIES, AND IF THEY FAIL TO GROW AS
ANTICIPATED, IT WOULD HARM OUR REVENUES.


    We derive the vast majority of our revenues from specialist activities. If
demand for our specialist services fails to grow, grows more slowly than we
currently anticipate or declines, our revenues would be adversely affected. We
expect our specialist activities to continue to account for the vast majority of
our revenues for the foreseeable future. Our future success will depend on:


    - continued growth in the volume of trading and the number of listings on
      the NYSE and the AMEX;


    - our ability to be chosen as the specialist for additional listing
      companies;


    - our ability to respond to regulatory and technological changes; and

    - our ability to respond to changing demands in the marketplace.

WE MAY HAVE DIFFICULTY SUCCESSFULLY MANAGING OUR GROWTH.

    Our business has grown significantly over the past five years, primarily due
to acquisitions we have made during this period. Our inability to successfully
and timely integrate the operations and personnel

                                       8

of the businesses we have acquired could have an adverse effect on our business,
financial condition and/or operating results. If the benefits of these
acquisitions do not meet the expectations of investors or financial or industry
analysts or if we do not successfully manage our growth, the market price of our
common stock may decline. The growth of our business has increased the demands
upon our management and operations. This growth has required, and will continue
to require, us to increase our investment in management personnel, financial and
management systems and controls, and facilities. The scope of procedures for
assuring compliance with applicable rules and regulations has changed as the
size and complexity of our business has increased. In response, we have
implemented formal compliance procedures which are regularly updated. Our future
operating results will depend on our ability to continue:

    - to improve our systems for operations, financial control, and
      communication and information management;

    - to refine our compliance procedures and enhance our compliance oversight;

    - to maintain a relationship with the customers of the firms we recently
      acquired (I.E., the companies in whose stocks they made a market prior to
      the acquisitions), as well as our ability to maintain our customer base;

    - to successfully integrate acquired firms' technologies; and

    - to retain and incentivize our employees.

TRADING THROUGH SPECIALISTS COULD BE REPLACED BY ALTERNATIVE TRADING SYSTEMS
WHICH COULD REDUCE OUR REVENUE.

    Alternative trading systems could reduce the levels of trading of
NYSE-listed and AMEX-listed securities executed through specialists. This, in
turn, could have an adverse effect on our revenues. Over the past few years, a
number of alternative trading systems have developed or emerged which may
compete with specialists by increasing trading in NYSE-listed and AMEX-listed
securities off the NYSE and AMEX trading floors and in over-the-counter markets.
In the future, similar new systems may continue to be developed and placed in
operation.

WE HAVE SIGNIFICANT INDEBTEDNESS AND INTEREST PAYMENT OBLIGATIONS.

    As of December 31, 2001, we had outstanding total consolidated debt in the
principal amount of approximately $431.5 million. These calculations of debt
exclude subordinated liabilities related to contributed exchange memberships.
LaBranche & Co. LLC also has the ability to borrow $200.0 million under a
revolving credit facility with a U.S. commercial bank. We also may need to incur
additional debt in the future for working capital or to complete acquisitions,
even though our existing debt obligations impose some limits on our ability to
do so. Our significant level of debt could have important consequences,
including the following:

    - our ability to obtain additional financing to fund our growth strategy,
      working capital, capital expenditures, debt service requirements or other
      purposes may be impaired;

    - our ability to use operating cash flow in other areas of our business will
      be limited because we must dedicate a substantial portion of these funds
      to make principal and interest payments;

    - we may be hindered from competing with other firms in our industry; and

    - our amount of debt may limit our flexibility to adjust to changing market
      conditions, changes in our industry and economic downturns.

    Our ability to satisfy our debt obligations will depend upon our future
operating performance and our ability to obtain additional debt or equity
financing. Prevailing economic conditions and financial,

                                       9

business and other factors, many of which are beyond our control, will affect
our ability to make these payments. If in the future we cannot generate
sufficient cash from operations to meet our debt obligations, we will need to
refinance our debt obligations, obtain additional financing or sell assets. We
cannot be sure that our business will generate cash flow or that we will be able
to obtain funding sufficient to satisfy our debt service requirements.

    Further, LaBranche & Co. LLC is a broker-dealer and a specialist regulated
by the SEC, the NYSE and the AMEX. Such regulations include strict rules
regarding capital requirements and approval for withdrawals of capital from, and
in some cases, other distributions by, a broker-dealer. These regulations could
prevent us from obtaining funds necessary to satisfy our obligations to pay
interest on or repay our indebtedness.

OUR ABILITY TO TAKE ACTIONS MAY BE RESTRICTED BY THE TERMS OF OUR INDEBTEDNESS.

    The covenants in our existing debt agreements, including LaBranche & Co.
LLC's credit agreement with a U.S. commercial bank, the note purchase agreements
relating to LaBranche & Co. LLC's senior subordinated indebtedness, the
indentures governing our senior notes and senior subordinated notes and any
future financing agreements, may adversely affect our ability to finance future
operations or capital needs or to engage in other business activities. These
covenants limit or restrict our ability and the ability of our subsidiaries to:

    - incur additional debt;

    - pay dividends and make distributions;

    - repurchase our securities;

    - make certain investments;

    - create liens on our assets;

    - transfer or sell assets;

    - enter into transactions with affiliates;

    - issue or sell stock of subsidiaries; or

    - merge or consolidate.

    In addition, the credit agreement and the note purchase agreements also
require LaBranche & Co. LLC to comply with certain financial ratios.
LaBranche & Co. LLC's ability to comply with these ratios may be affected by
events beyond our or its control. If any of the covenants in the credit
agreement, the note purchase agreements or the indentures relating to our senior
notes and senior subordinated notes is breached, or if LaBranche & Co. LLC is
unable to comply with required financial ratios, it may be in default under the
credit agreement or the note purchase agreements and we may be in default under
the indentures relating to our senior notes and senior subordinated notes. A
significant portion of our indebtedness then may become immediately due and
payable. We are not certain whether we would have, or be able to obtain,
sufficient funds to make these accelerated payments. Compliance with the
covenants is also a condition to borrowings under the credit agreement.

WE ARE REQUIRED TO TAKE ACTIONS UPON THE OCCURRENCE OF A CHANGE OF CONTROL.

    Upon the occurrence of a change of control, we will be required to offer to
repurchase all of our outstanding senior notes and senior subordinated notes at
a price equal to 101% of their principal amount, together with accrued and
unpaid interest, if any, to the date of repurchase. Certain important corporate
events, such as leveraged recapitalizations that would increase our level of
indebtedness, would not constitute a change of control. If a change of control
were to occur, it is possible that we

                                       10

would not have sufficient funds to repurchase our outstanding senior notes and
senior subordinated notes or that restrictions in LaBranche & Co. LLC's credit
agreement, the note purchase agreements relating to LaBranche & Co. LLC's senior
subordinated indebtedness, the indentures governing our senior notes and senior
subordinated notes will not allow such repurchases. Furthermore, a change of
control will most likely trigger a default under LaBranche & Co. LLC's credit
agreement, the note purchase agreements relating to LaBranche & Co. LLC's senior
subordinated indebtedness and the indentures governing our senior notes and
senior subordinated notes. To the extent we do not have sufficient funds to meet
our repurchase obligations and any other obligations in respect of the credit
agreement, the note purchase agreements and the indentures relating to our
senior notes and senior subordinated notes, we would necessarily seek
third-party financing. However, it is possible that we will not be able to
obtain such financing.

WE MAY HAVE INSUFFICIENT CAPITAL IN THE FUTURE AND MAY BE UNABLE TO SECURE
ADDITIONAL FINANCING WHEN WE NEED IT.

    Our business depends on the availability of adequate capital. We cannot be
sure that we will have sufficient capital in the future or that additional
financing will be available on a timely basis, or on terms favorable to us.
Historically, we have satisfied these needs with internally generated funds, our
bank credit facilities and the issuance of subordinated debt by our operating
subsidiaries and the issuance of senior notes, senior subordinated notes and
common stock. We currently anticipate that our available cash resources and
credit facilities will be sufficient to meet our anticipated working capital,
regulatory capital and capital expenditure requirements for the foreseeable
future.

    We may, however, need to raise additional funds to:

    - increase the capital available to us for our inventory positions;

    - support more rapid expansion;

    - acquire complementary businesses; or

    - respond to unanticipated capital requirements.

    We may be required to obtain this additional financing on short notice as a
result of rapid, unanticipated developments, such as a steep market decline.

OUR SUCCESS DEPENDS ON OUR ABILITY TO ACCURATELY PROCESS AND RECORD OUR
TRANSACTIONS, AND ANY FAILURE TO DO SO COULD SUBJECT US TO LOSSES.

    Our specialist activities require us to accurately record and process a very
large number of transactions on a daily basis. Any failure or delay in recording
or processing transactions could cause substantial losses for brokers, their
customers and/or us and could subject us to claims for losses. We rely on our
staff to operate and maintain our information and communications systems
properly, and we depend on the integrity and performance of those systems. Our
recording and processing of trades is subject to human and processing errors.
Moreover, extraordinary trading volume or other events could cause our
information and communications systems to operate at an unacceptably low speed
or even fail. Any significant degradation or failure of our information systems
or any other systems in the trading process could cause us to fail to complete
transactions or could cause brokers who place trades through us to suffer delays
in trading.

                                       11

RECENT TERRORIST ATTACKS HAVE CONTRIBUTED TO ECONOMIC INSTABILITY IN THE UNITED
STATES; CONTINUED TERRORIST ATTACKS, WAR OR OTHER CIVIL DISTURBANCES COULD LEAD
TO FURTHER ECONOMIC INSTABILITY AND DEPRESS OUR STOCK PRICE.

    On September 11, 2001, the United States was the target of terrorist attacks
of unprecedented scope, with the attacks in New York City particularly affecting
our operations. These attacks may cause long-term instability in the global
financial markets. This instability has resulted in a slowdown in the employment
sector as companies assess the impact of the attacks on their operations and on
their employment needs. The United States is also currently conducting military
operations in response to the terrorist attacks. These attacks and the United
States military campaign may lead to substantial armed hostilities or to further
acts of terrorism and civil disturbances in the United States or elsewhere,
which may contribute further to economic instability in the United States and
could have a material adverse effect on our business, financial condition and
operating results.

    In addition, our offices are located in close proximity to the terrorist
attacks on the World Trade Center on September 11, 2001. The aftermath of the
attacks on the World Trade Center and the resulting air-quality issues in our
building required us to close our operations and temporarily relocate our
offices. The NYSE also was forced to stop operating for four consecutive trading
days, which caused our operations to halt and could have compromised the
liquidity of that market during closure. If additional terrorist attacks occur
in close proximity to our offices, or upon our office buildings, the NYSE or the
AMEX, we could be forced to relocate for a longer period of time, or
permanently. Furthermore, additional terrorist attack in New York City, or on
our buildings, the NYSE or the AMEX, or additional armed hostilities within the
United States, could cause significant delays or stoppages in our business
activities, which would significantly harm our revenues and profits.

OUR INFORMATION OR COMMUNICATION SYSTEMS MAY FAIL AND INTERRUPT OUR BUSINESS.

    Any information or communication systems failure or decrease in information
or communications systems performance that causes interruptions in our
operations could have an adverse effect on our business, financial condition
and/or operating results. Our systems may fail as a result of:

    - hardware or software failure; or

    - power or telecommunications failure.

    The September 11, 2001 terrorist attacks, particularly the attacks on the
World Trade Center, caused a temporary lapse in our information and
communications systems. It is possible that additional terrorist attacks may
occur in the future without warning and that such attacks could compromise or
disable our systems. Although we have established a back-up disaster recovery
center in New Jersey, it may not be effective in preventing an interruption of
our business. It is also possible that any future terrorist activities or an act
of war in retaliation against the current United States military campaign could
harm our operations and/or disaster recovery center, which could significantly
harm our business.

WE DEPEND ON THE NYSE, THE AMEX AND CLEARING AND DEPOSITORY INSTITUTIONS TO
EFFECT TRADES, AND THEIR FAILURE TO PERFORM COULD SUBJECT US TO LOSSES.

    We are dependent on the proper and timely function of complex information
and communications systems maintained and operated by or for the NYSE, the AMEX
and clearing and depository institutions. Failures or inadequate or slow
performance of any of those systems could adversely affect our ability to
operate and complete trades. The chances of such failures or inadequacies would
likely escalate if there are additional terrorist attacks in New York City, the
United States or elsewhere or if the current United States military campaign
becomes a widespread war. The failure to complete trades on a timely basis could
subject us to losses and claims for losses of brokers and their customers.

                                       12

OUR FUTURE SUCCESS WILL DEPEND ON OUR ABILITY TO UPGRADE OUR INFORMATION AND
COMMUNICATIONS SYSTEMS, AND ANY FAILURE TO DO SO COULD HARM OUR BUSINESS AND
PROFITABILITY.

    The development of complex communications and new technologies, including
Internet-based technologies, may render our existing information and
communications systems outdated. In addition, our information and communications
systems must be compatible with those of the NYSE and the AMEX. As a result, if
the NYSE or the AMEX upgrades its systems, we will need to make corresponding
upgrades. Our future success will depend on our ability to respond to changing
technologies on a timely and cost-effective basis. We cannot be sure that we
will be successful in upgrading our information and communications systems on a
timely or cost-effective basis. Our failure to do so could have an adverse
effect on our business, financial condition and/or operating results.

    The NYSE's ability to develop information and communications systems and
complex computer and other technology systems has been instrumental in its
recent growth and success. We are dependent on the continuing development of
technological advances by the NYSE and the AMEX, a process over which we have no
control. If the NYSE for any reason is unable to continue its recent history of
computer-related and other technological developments and advances, it could
have an adverse effect on the success of the NYSE, including its ability to
grow, to manage its trading volumes and to attract new listings. Any such
developments can be expected to adversely affect our operations, financial
condition and operating results.

IF WE LOSE THE SERVICES OF OUR KEY PERSONNEL OR CANNOT HIRE ADDITIONAL QUALIFIED
PERSONNEL, OUR BUSINESS WILL BE HARMED.

    Our future success depends on the continued service of key employees,
particularly Michael LaBranche, our Chairman, Chief Executive Officer and
President. The loss of the services of any of our key personnel or the inability
to identify, hire, train and retain other qualified personnel in the future
could have an adverse effect on our business, financial condition and/or
operating results. We have employment agreements with Mr. LaBranche and other
key employees. We also maintain "key person" life insurance policies on
Mr. LaBranche and other key employees. Competition for key personnel and other
highly qualified management, trading, compliance and technical personnel is
intense. We cannot assure you that we will be able to attract new or retain
currently employed highly qualified personnel in the future.

    In connection with our 1999 reorganization from partnership to corporate
form and initial public offering of our common stock, a number of our current
managing directors received substantial amounts of our common stock in exchange
for their partnership interests. Because the shares of common stock were
received in exchange for partnership interests, ownership of the shares is not
dependent upon the continued employment of those managing directors. In
addition, many of our employees who are not managing directors have received
grants of stock options and restricted stock units. The steps we have taken to
encourage the continued service of these individuals, who include key senior
personnel, may not be effective.

WE ARE SUBJECT TO INTENSE COMPETITION FOR NEW LISTINGS, AND OUR PROFITABILITY
WILL SUFFER IF WE DO NOT COMPETE EFFECTIVELY.

    We cannot be sure that we will be able to compete effectively with current
or future competitors. Our failure to compete effectively would have an adverse
effect on our profitability. We obtain all our new listings on the NYSE by going
through an allocation process. In this process, either a committee of the NYSE
or the listing company chooses the specialist. The competition for obtaining new
listing companies is intense. We expect competition to continue and intensify in
the future. Some of our competitors may have significantly greater financial and
other resources than we have and may have greater name recognition. These
competitors may be able to respond more quickly to new or evolving opportunities
and listing company requirements. They also may be able to undertake more
extensive

                                       13

promotional activities to attract new listing companies. In addition, the
specialist industry has recently been consolidating. The combined companies
resulting from this consolidation may have a stronger capital base. This trend
has intensified the competition in our industry. Finally, the NYSE retains the
ability to name new specialist firms.

THE FAILURE BY US OR OUR EMPLOYEES TO COMPLY WITH APPLICABLE LAWS AND
REGULATIONS COULD RESULT IN SUBSTANTIAL FINES AND OTHER PENALTIES.

    The securities industry is subject to extensive regulation under both
federal and state laws. In addition, the SEC, the NYSE, the AMEX, other
self-regulatory organizations, commonly referred to as SROs, and state
securities commissions require strict compliance with their respective rules and
regulations. Failure to comply with any of these laws, rules or regulations
could result in serious adverse consequences. We and our officers and employees
may be subject in the future to claims arising from acts in contravention of
these laws, rules and regulations. An adverse ruling against us and/or our
officers and other employees as a result of any of these claims could result in
us and/or our officers and other employees being required to pay a substantial
fine or settlement. It could also result in the suspension or revocation of our
registration with the SEC as a broker-dealer or our suspension or expulsion as a
member firm of the NYSE and the AMEX. If this occurred, we would be unable to
operate our business. As a result of our recent acquisitions, the number of our
employees has increased significantly, and our lack of experience working with
these employees increases the risk that we will not detect or deter employee
misconduct.

THE REGULATORY ENVIRONMENT IN WHICH WE OPERATE MAY CHANGE, MAKING IT DIFFICULT
FOR US TO REMAIN IN COMPLIANCE.

    The regulatory environment in which we operate is subject to change which we
cannot predict. It may be difficult for us to comply with new or revised
legislation or regulations imposed by the SEC, other U.S. or foreign
governmental regulatory authorities and SROs, including the NYSE and the AMEX.
Failure to comply would have an adverse effect on our business, financial
condition and/or operating results. Changes in the interpretation or enforcement
of existing laws and rules by the SEC, these governmental authorities, SROs, the
NYSE and the AMEX also could have an adverse effect on our business, financial
condition and/or operating results.


FAILURE TO COMPLY WITH NET CAPITAL AND NET LIQUID ASSET REQUIREMENTS MAY RESULT
IN THE REVOCATION OF OUR REGISTRATION WITH THE SEC OR OUR EXPULSION FROM THE
NYSE AND/OR THE AMEX.


    The SEC, the NYSE, the AMEX and various other regulatory agencies have
stringent rules with respect to the maintenance of minimum levels of capital and
net liquid assets by securities brokers-dealers as well as specialist firms.
Effective October 30, 2000, the NYSE increased its minimum net liquid asset
requirements. LaBranche & Co. LLC currently is required to maintain minimum net
liquid assets of approximately $446.0 million. Failure to maintain the required
net capital and net liquid assets may subject us to suspension or revocation of
our SEC registration or suspension or expulsion by the NYSE and/or the AMEX. If
this occurred, we would be unable to operate our business. In addition, a change
in these rules, the imposition of new rules or any unusually large requirement
or charge against our regulatory capital could limit any of our operations that
require the intensive use of capital. These rules could also restrict our
ability to withdraw capital from LaBranche & Co. LLC. Any limitation on our
ability to withdraw capital from LaBranche & Co. LLC could limit our ability to
pay cash dividends, repay debt and repurchase shares of our outstanding stock. A
substantial market decline, a significant operating loss or any unusually large
requirement or charge against regulatory capital could adversely affect our
ability to expand or even maintain our present levels of business, which could
have an adverse effect on our business, financial condition and/or operating
results.

                                       14

EMPLOYEE MISCONDUCT IS DIFFICULT TO DETECT AND DETER AND COULD RESULT IN LOSSES.

    There have been a number of highly publicized cases involving fraud, stock
manipulation or other misconduct by employees in the financial services industry
in recent years, and we run the risk that employee misconduct could occur.
Misconduct by employees could include binding us to transactions that exceed
authorized limits or present unacceptable risks, or hiding from us unauthorized
or unsuccessful activities, which, in either case, may result in unknown and
unmanaged risks or losses. Employee misconduct could also involve the improper
use or disclosure of confidential information, which could result in regulatory
sanctions and serious reputational or financial harm. It is not always possible
to deter employee misconduct and the precautions we take to prevent and detect
this activity may not be effective in all cases.

WE ARE SUBJECT TO RISK RELATING TO LITIGATION AND POTENTIAL SECURITIES LAWS
LIABILITY.

    Many aspects of our business involve substantial risks of liability. A
specialist is exposed to substantial risks of liability under federal and state
securities laws, other federal and state laws and court decisions, as well as
rules and regulations promulgated by the SEC, the NYSE and the AMEX. We also are
subject to the risk of litigation and claims that may be without merit. We could
incur significant legal expenses in defending ourselves against such lawsuits or
claims. An adverse resolution of any future lawsuits or claims against us could
have an adverse effect on our business, financial condition and/or operating
results.

COUNTERPARTIES MAY FAIL TO PAY US.

    As a specialist in listed stocks, our securities transactions are conducted
as principal with broker-dealer counterparties located in the United States. The
NYSE, the AMEX and the clearing houses monitor the credit standing of the
counterparties with which we conduct business. However, we cannot assure you
that any of these counterparties will not default on their obligations. If any
do, our business, financial condition and/or operating results could be
adversely affected.

SOME OF OUR EXECUTIVE OFFICERS ARE IN A POSITION TO CONTROL MATTERS REQUIRING A
STOCKHOLDER VOTE.

    Certain of our managing directors, including the selling stockholders, who
currently own approximately 58.6% of our outstanding common stock have entered
into a stockholders' agreement under which they have agreed, among other things,
that their shares of our common stock will be voted, for as long as they own
their shares, as directed by a majority vote of Michael LaBranche, our Chairman,
Chief Executive Officer and President, James G. Gallagher and Alfred O. Hayward,
Jr., each an executive officer and director. Accordingly, these individuals have
the ability to control all matters requiring approval by our common
stockholders. These matters include the election and removal of directors and
the approval of any merger, consolidation or sale of all or substantially all of
our assets. In addition, they are able to dictate the management of our business
and affairs. This concentration of ownership could have the effect of delaying,
deferring or preventing a change in control, a merger or consolidation, a
takeover or another business combination.

    In addition, in our acquisition of ROBB PECK McCOOEY Financial
Services, Inc., we issued an aggregate of 100,000 shares of our Series A
preferred stock to its former stockholders. The holders of our Series A
preferred stock have the opportunity to vote on certain matters that would
affect their rights as holders of Series A preferred stock, any issuance of our
capital stock with rights greater than or equal to theirs, and any proposal for
our merger or consolidation, the sale of more than 50% of our consolidated
assets or any similar transaction. At the time of our January 18, 2002 offer to
purchase up to 30,000 of the outstanding shares of Series A preferred stock,
George E. Robb, Jr., one of our directors, and Robert M. Murphy, one of our
directors and the Chief Executive Officer of our LaBranche & Co. LLC subsidiary,
beneficially owned an aggregate of approximately 65.6% of our Series A preferred
stock. This concentration of ownership, therefore, also could have the effect of

                                       15

delaying, deferring or preventing a change in control, a merger or
consolidation, a takeover or another business combination.

FUTURE SALES BY EXISTING STOCKHOLDERS COULD DEPRESS THE MARKET PRICE OF OUR
COMMON STOCK.


    If our stockholders sell substantial amounts of our common stock in the
public market, the market price of our common stock could fall. Such sales also
might make it more difficult for us to sell equity securities in the future at a
time and price that we deem appropriate. As of December 31, 2001, we had
outstanding 58,733,955 shares of common stock. Certain of our managing
directors, including the selling stockholders, who collectively own 34,411,343
shares of common stock, are party to a stockholders' agreement. Under the
stockholders' agreement, the restricted shares held by our managing directors
will be eligible for sale in the public market as follows:



    - 11,287,115 shares beginning August 24, 2002;


    - 11,562,114 shares beginning August 24, 2003; and

    - 11,562,114 shares beginning August 24, 2004.


    If large amounts of these shares are sold within a short period of time, the
market price of our common stock would likely fall.


    In addition, our directors and executive officers have agreed not to
transfer their shares of our common stock for a period of 90 days after
January   , 2002. Subject to volume limitations under Rule 144, these directors
and officers would be able to publicly sell substantial amounts of our common
stock and thereby may depress the market price for our common stock.

UNCERTAINTIES ASSOCIATED WITH OUR ACQUISITIONS MAY CAUSE US TO LOSE KEY
PERSONNEL.

    Our current and prospective employees may experience uncertainty about their
future roles with us due to the integration of our newly-acquired employees and
businesses into ours. This uncertainty may adversely affect our ability to
attract and retain key personnel, which would adversely affect our business and
results of operations.

                                USE OF PROCEEDS

    All proceeds from the sale of the shares of our common stock to which this
prospectus relates will go to the selling stockholders. Accordingly, we will not
receive any of the proceeds from the sale of the shares of our common stock
offered by this prospectus.

                                DIVIDEND POLICY

    We have never declared or paid any dividends on our common stock. We
currently anticipate that all future earnings will be retained by us to support
our growth strategy. Accordingly, we do not anticipate paying cash dividends on
our common stock in the foreseeable future. The payment of any future dividends
will be at the discretion of our board of directors and will depend upon, among
other things, our future earnings, operations, capital requirements, the general
financial condition, contractual restrictions and general business conditions.

    In connection with our acquisition of ROBB PECK McCOOEY Financial Services,
Inc., we issued 100,000 shares of our Series A preferred stock to its
stockholders. On January 18, 2002, we commenced an offer to purchase up to
30,000 of the shares of Series A preferred stock. See "Summary--Recent
Developments--Offer to Repurchase Preferred Stock." Each outstanding share of
our Series A preferred stock entitles the holder to cumulative preferred cash
dividends at an annual rate of 8% of the liquidation preference until March 15,
2005, 10% until March 15, 2006 and 10.8% thereafter. Dividends are payable on
the first day of January and the first day of July of each year (or if such date
is not a regular business day, then the next business day thereafter). Dividends
on the issued and outstanding shares of Series A preferred stock are preferred
and cumulative and accrue from the date on which they were originally issued.

                                    BUSINESS

    THE FOLLOWING DESCRIPTION OF OUR BUSINESS CONTAINS FORWARD LOOKING
STATEMENTS, WHICH INVOLVE RISKS AND UNCERTAINTIES. OUR RESULTS COULD DIFFER
MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD LOOKING STATEMENTS AS A
RESULT OF SOME FACTORS. SEE "RISK FACTORS."

OVERVIEW

    We are a holding company that is the sole member of LaBranche & Co. LLC and
owns all the outstanding stock of LaBranche Financial Services, Inc. Founded in
1924, LaBranche & Co. LLC is one of the oldest and largest specialist firms on
the NYSE. We also act as a specialist in stocks and options on the AMEX. Our
LaBranche Financial Services, Inc. subsidiary is a clearing broker for customers
of introducing brokers, provides direct access floor brokerage services to
institutional customers, provides securities clearing and other related services
to individual and institutional clients, including traders, professional
investors and broker-dealers, and provides front-end order execution, analysis
and reporting solutions for the wholesale securities dealer market.

    As a specialist, our role is to maintain, as far as practicable, a fair and
orderly market in our specialist stocks. In doing so, we provide a service to
our listed companies, and to the brokers, traders and their respective customers
who trade in our specialist stocks. We believe that, as a result of our
commitment to providing high quality specialist services, we have developed a
strong reputation among our constituencies, including investors, members of the
Wall Street community and our listed companies.

    Our business has grown considerably during the past five years. Our revenues
have increased from about $49.9 million in 1996 to $424.1 million in 2001,
representing a compound annual growth rate of 53.4%. We have accomplished our
growth both internally and through selective acquisitions. For example, since
the NYSE implemented its new specialist allocation process in March 1997, we
have been selected by 87 new listed companies, resulting from 178 listing
interviews. In addition, we have acquired ten specialist operations since 1997,
adding over 550 NYSE and AMEX common stocks and 107 AMEX-listed options for
which we act as the specialist. During the past five years, we have also
increased the scope of our business, as illustrated by the following data:

    - the annual dollar volume on the NYSE of stocks for which we acted as
      specialist increased to $2.5 trillion in 2001, from $201.4 billion in
      1996. Based on these dollar volumes, we were the largest NYSE specialist
      firm in 2001 as compared to the sixth largest in 1996;

    - the annual share volume on the NYSE of stocks for which we act as
      specialist increased to 76.0 billion in 2001, as compared to 5.6 billion
      in 1996. Based on these share volumes, we were the largest NYSE specialist
      firm in 2001 as compared to the fourth largest in 1996; and

    - the total number of our NYSE common stock listings increased to 591 as of
      December 31, 2001, from 132 as of December 31, 1996. Based on the number
      of our common stock listings, we were the largest specialist firm as of
      December 31, 2001 as compared to the fourth largest as of December 31,
      1996. In addition, we acted as the specialist for 266 other NYSE-listed
      securities (e.g., preferred and convertible securities) and for 57 stocks
      and 122 options on the AMEX.

    As of December 31, 2001, our listed companies included:

    - 104 of the S&P 500 companies; and

    - nine of the 30 companies comprising the Dow Jones Industrial Average.
      These listed companies are American Express, AT&T, DuPont, Eastman Kodak,
      Exxon Mobil, Merck, Minnesota Mining & Manufacturing, Phillip Morris and
      SBC Communications.

INDUSTRY BACKGROUND

  THE NYSE

    The NYSE is currently the largest securities market in the world. The market
capitalization of all U.S. shares listed on the NYSE increased from about $6.8
trillion at December 31, 1996 to about $11.9 trillion at December 31, 2001,
representing a compound annual growth rate of 11.8%.

    The NYSE's average daily trading volume increased from 178.9 million shares
in 1991 to 1.24 billion shares in 2001, as illustrated by the following graph:

    Trading on the NYSE takes place through open bids to buy and open offers to
sell made by NYSE members, acting as principal or as agent for institutions or
individual investors. Buy and sell orders meet directly on the trading floor
through an auction process, and prices are determined by the interplay of supply
and demand in that auction. In order to buy and sell securities on the NYSE, a
person must first be accepted for membership in the NYSE. The number of
memberships, or seats, is presently limited to 1,366, and the price of a
membership depends on supply and demand. Based on recent transfers of
memberships, the market price of a membership on the NYSE is about
$2.2 million. To become a member, each prospective applicant must also pass an
examination covering NYSE rules and regulations.

    NYSE members are generally categorized based upon the activities in which
they engage on the trading floor, such as specialists or brokers. The largest
single membership group is floor brokers, which consists of both commission
brokers and independent brokers. Commission brokers are employed by
broker-dealer firms that are members of the NYSE and earn salaries and
commissions. Independent floor brokers are brokers who independently handle
orders for other broker-dealers and financial institutions.

  THE NYSE SPECIALIST

    All trading of securities on the NYSE is conducted through an auction
process. The auction process for each security is managed by the exclusive
specialist for that security. The specialist is a broker-dealer who applies for
and, if accepted, is assigned the role to maintain a fair and orderly

                                       21

market in its specialist stocks. The number of specialist units on the NYSE has
decreased from 37 at December 31, 1996 to nine at December 31, 2001. A recently
announced transaction, if consummated, would further reduce the number of
specialist units on the NYSE to eight. Of the nine specialist units, the three
largest specialist units as ranked by their number of specialist stocks were
responsible for about 56.0% and 69.6% of the average daily trading volume, as
measured by dollar volume, in 2000 and 2001, respectively.

    A specialist firm is granted a franchise by the NYSE to conduct the auction
in each NYSE-listed stock. Specialist firms conduct their auctions at specific
trading posts located on the floor of the NYSE. Because the specialist firm runs
the auction in its specialist stocks, it knows of all bids and offers in those
stocks and gathers orders to price its stocks appropriately.

    Specialist firms compete for the original listing of stocks through an
allocation process organized by the NYSE. As part of this allocation process,
companies seeking a listing may select a specialist firm in one of two ways.
Under the first method, the NYSE's allocation committee selects the specialist
firm based on specific criteria. Under the second method, available since
March 1997, the listing company requests that the allocation committee select
three to five potential specialist firms suitable for the stock, based on
criteria specified by the listing company. The listing company then has the
opportunity to meet with each specialist firm identified by the allocation
committee. Within one week after meeting the competing specialist firms, the
listing company must select one specialist firm. Currently, substantially all of
the companies seeking a listing on the NYSE opt to make the final choice of
their own specialist firm under the second allocation method.

    When assigned a particular stock, the specialist firm agrees to specific
obligations. The specialist firm's role is to maintain, as far as practicable,
trading in the stock that will be fair and orderly. This implies that the
trading will have reasonable depth and price continuity, so that, under normal
circumstances, a customer may buy or sell stock in a manner consistent with
market conditions. A specialist firm helps market participants achieve price
improvement in their trades because the best bids and offers are discovered
through the auction process. In performing its obligations, the specialist firm
is exposed to all transactions that occur in each of its specialist stocks on
the NYSE floor. In any given transaction, the specialist firm may act as:

    - an auctioneer by setting opening prices for its specialist stocks and by
      matching the highest bids with the lowest offers, permitting buyers and
      sellers to trade directly;

    - a facilitator bringing together buyers and sellers who do not know of each
      other in order to execute a trade which would not otherwise occur;

    - an agent for broker-dealers who wish to execute transactions as instructed
      by their customers (typically, these orders are limit orders entrusted to
      the specialist at prices above or below the current market price); or

    - a principal using its own capital to buy or sell stocks for its own
      account.

    The specialist firm's decision to buy or sell shares of its specialist
stocks as principal for its own account may be based on obligation or
inclination. For example, the specialist firm may be obligated to buy or sell
its specialist stock to counter short-term imbalances in the prevailing market,
thus helping to maintain a fair and orderly market in that stock. At other
times, the specialist firm may be inclined to buy or sell the stock as principal
based on attractive opportunities. The specialist firm may trade at its election
so long as the trade will contribute to a fair and orderly market. In
actively-traded stocks, the specialist firm continually buys and sells its
specialist stocks at varying prices throughout each trading day. The specialist
firm's goal and expectation is to profit from differences between the prices at
which it buys and sells these stocks. In fulfilling its specialist obligations,
however, the specialist firm may, at times, be obligated to trade against the
market, adversely impacting the profitability of the trade. In

                                       22

addition, the specialist firm's trading practices are subject to a number of
restrictions, as described in "Operations--NYSE Rules Governing our Specialist
Activities."

  RECENT TRENDS IN NYSE TRADING AND THE NYSE SPECIALIST'S ROLE

    Specialist firms generate revenues by executing trades, either as agent or
principal, in their specialist stocks. Accordingly, the specialist firms'
revenues are primarily driven by the volume of trading on the NYSE. This volume
has increased significantly in recent years. The increase in trading volume has
resulted from a number of factors, including:

    - an increase in the number of households investing in stocks;

    - an increase in the amount of assets managed through retirement plans,
      mutual funds, annuity and insurance products, index funds and other
      institutional investment vehicles;

    - the increased popularity and use of computerized trading, hedging and
      other derivative strategies;

    - an increase in NYSE-listed stocks due to:

       - transfers from Nasdaq;

       - an increase in listings of foreign companies; and

       - initial public offerings and spin-offs;

    - higher equity portfolio turnover by individuals and institutional
      investors as a result of lower commission rates and other transaction
      costs;

    - trading in decimal price increments;

    - an increase in the amount of shares traded due to stock splits and stock
      dividends; and

    - on-line trading.

    These factors have, in turn, been influenced by low interest rates and low
levels of inflation.

    The NYSE has commenced trading in decimals and has increased the window for
providing commission-free execution of a trade to five minutes from the previous
two minutes. The NYSE is also considering the following additional changes:

    - longer trading days; and

    - trading of foreign stocks in ordinary form side by side with their
      American Depositary Receipts.

    We believe that trading in decimals and, if instituted, these additional
changes will likely contribute to additional growth in NYSE trading volume.

    The majority of trades in NYSE-listed stocks take place through NYSE
specialist firms. In 2001, specialist firms handled about 83.6% of trades in
NYSE-listed stocks. Trades in NYSE-listed stocks also are generally effected as
follows:

    - some stocks are listed on multiple exchanges, such as regional exchanges,
      and trades take place on those exchanges;

    - NYSE members may trade NYSE-listed stocks off the NYSE in the
      over-the-counter market; and

    - non-NYSE members may trade NYSE-listed stocks off the NYSE in
      over-the-counter markets.

    Technological advances have contributed to the increased trading through
alternative trading systems, called ATSs, such as electronic communications
networks, or ECNs, and crossing systems.

                                       23

While the first ECN was created in 1969, most of the others currently in
operation were started in the past few years. These systems electronically
facilitate the matching of buy and sell orders that are entered by their network
members. If a match does not occur, some ATSs will forward unfilled orders to
other ATSs or to exchanges such as the NYSE. Some of these networks also allow
limited negotiation between members to facilitate a match. These ATSs generally
limit trades over their systems to their members, who are typically large
financial institutions, well-capitalized traders or brokerage firms.
Additionally, some ATSs have been developed to facilitate trading by retail
investors. In April 1999, the SEC ruled that these networks are allowed, and in
specified cases are required, to register and become subject to regulation as
stock exchanges.

    The percentage of annual trading of NYSE-listed stocks on the NYSE has
ranged from 82.5% to 83.7% for the past five years. It is unclear, however, how
the alternative trading methods and new technologies just described or that may
be developed will affect the percentage of trading in listed stocks conducted on
the NYSE. The NYSE has indicated that it is studying the possibility of
embracing electronic communications network technology to expand trading. ATSs
may be developed, organized and operated by large brokerage houses and
investment banks with more substantial capital, better access to technology and
direct access to investors. As a result, these parties may be well positioned to
direct trading to ATSs. These alternative trading methods may account for a
growing percentage of the trading volume of NYSE-listed stocks.

    The accelerating growth of trading volume, the increase in stock prices on
the NYSE in the 1990s and the more recent increased volatility of stock prices
have increased the demands upon specialists. In order to fulfill their
obligations, specialists are required to execute a greater number of trades in a
shorter period of time with greater price volatility. In addition, specialists
are called upon to take larger positions in their specialist stocks. These
factors have led to a consolidation of specialist units in the past five years.
We believe that the NYSE specialist market is becoming increasingly dominated by
a number of large, better-capitalized specialist firms that are able to provide
an enhanced level of service.

LABRANCHE'S COMPETITIVE POSITION

    We are committed to providing the highest quality service to our various
constituencies. We believe our success is based on the following factors:

    - LEADING POSITION IN THE SPECIALIST MARKET. We have a long-standing
      reputation as one of the leading specialist firms on the NYSE. We have
      successfully grown our business and improved our services through widely
      varying market conditions. Trading in the stocks for which we acted as
      specialist during 2001 accounted for 27.6% of the dollar volume on the
      NYSE and 28.5% of the share volume. Based on these percentages, we were
      the largest specialist firm on the NYSE. We are continuing to develop our
      relationships with ATSs and to embrace new technologies in trading
      platforms.

    - DIVERSE AND HIGH QUALITY SPECIALIST STOCKS. Our listed companies operate
      in a variety of industries including financial services, media, oil and
      gas, retail, technology and telecommunications. Many of our listed
      companies are leaders in their respective fields. We believe that acting
      as specialist in the stocks of industry leaders will benefit us as these
      leading companies continue to expand their businesses through internal
      growth and acquisitions.


    - STRONG MARKET-MAKING SKILLS. We utilize our strong market-making skills to
      actively trade as principal in our specialist stocks. We believe that we
      significantly improve liquidity in our specialist stocks, particularly
      during periods of market volatility. In 2001, approximately 33.4% of our
      trades were as principal as compared to an average of approximately 30.6%
      for all NYSE specialists.


                                       24

    - INNOVATIVE CUSTOMER-ORIENTED SERVICES. We are committed to providing our
      listed companies with a high level of service, in addition to our
      specialist functions on the trading floor. We provide our listed companies
      with detailed reports on the trading activity of their stocks. We also
      maintain frequent contact with a majority of our listed companies to
      discuss the trading in their stock. In addition, we were the first
      specialist firm to:

       - host an annual listed company conference;

       - publish a company newsletter; and

       - commission customer satisfaction surveys from our listed companies.

    - COMPLETED SPECIALIST ACQUISITIONS. Since 1997, we have acquired the
      following ten specialist operations, solidifying our position as one of
      the leading specialist firms:

       - a portion of the specialist operations of Stern Bros., LLC
         (July 1997);

       - Ernst, Homans, Ware & Keelips (August 1997);

       - Fowler, Rosenau & Geary, LLC (July 1998);

       - Henderson Brothers, Inc. (March 2000);

       - Webco Securities, Inc. (March 2000);

       - the assets and operations of an AMEX options specialist unit that acted
         as the specialist in the options of 21 common stocks (December 2000);

       - ROBB PECK McCOOEY Financial Services, Inc. (March 2001);


       - the assets and operations of an AMEX specialist firm, Cranmer &
         Cranmer, Inc. (August 2001);


       - the 75% interest that we did not previously own in the specialist
         business conducted as a joint account by us, R. Adrian & Company, LLC
         and Freedom Specialist Inc. (September 2001); and

       - Bocklet & Company, LLC (October 2001).

    - OTHER ACQUISITIONS. In March 2001, we also acquired Internet Trading
      Technologies, Inc., a company providing front-end order execution,
      analysis and reporting solutions for the wholesale securities dealer
      market.

    Our objective is to continue the growth in our revenues and profits by
continuing to be aggressive in positioning ourselves in the NYSE allocation
process. Between March 1997, when the NYSE adopted the new allocation procedure,
and December 31, 2001, we participated in 178 selection pools for listed
companies and were selected by management of the listed companies in 87 of them.

                                       25

OPERATIONS

  NYSE RULES GOVERNING OUR SPECIALIST ACTIVITIES

    Under the NYSE rules, a specialist has a duty to maintain, as far as
practicable, a fair and orderly market in its specialist stocks. In order to
fulfill its obligations, the specialist must at times trade for its own account,
even when it may adversely affect the specialist's profitability. In addition,
under some circumstances, the specialist is prohibited from making trades as
principal in its specialist stocks. The specialist's obligations are briefly
described below.

    REQUIREMENT TO TRADE AS PRINCIPAL.  A specialist must buy and sell
securities as principal when necessary to minimize an actual or reasonably
anticipated short-term imbalance between supply and demand in the auction
market. The specialist must effect these transactions when their absence could
result in an unreasonable lack of continuity and/or depth in their specialist
stocks. The specialist is not expected to act as a barrier in a rising market or
a support in a falling market, but must use its own judgment to try to keep such
price increases and declines equitable and consistent with market conditions.

                                       26

    A specialist must make firm and continuous two-sided quotations that are
timely and that accurately reflect market conditions. In making these
quotations, the specialist's transactions are calculated to contribute to the
maintenance of price continuity with reasonable depth. Following is an
illustration of how a specialist acts as principal to maintain price continuity:

    The most recent sale in a listed stock was $50, the best public bid (to buy)
on the specialist's book is $49.75, and the best public offer (to sell) on the
book is $50.25. A broker who wants to buy 100 shares at the market in this
instance without a specialist would purchase at $50.25, the offer price.
Similarly, a broker seeking to sell 100 shares without a specialist would
receive $49.75 the bid price. The specialist, who is expected to provide
reasonable price continuity, in this case might narrow the quote spread by
offering or bidding for stock for its own account. In this instance, the broker
who wants to buy 100 shares might buy at $50.0625 from the specialist, as
opposed to buying the same amount of shares from the best offer of $50.25,
thereby offering price improvement to the customer. In the next trade, a broker
willing to sell 100 shares might sell to the specialist at $50, as opposed to
selling to the best available bid of $49.75, again achieving price improvement
for the customer.

    TRADING RESTRICTIONS.  In trading for its own account, the specialist must
avoid initiating a market-destabilizing transaction. All purchases and sales
must be reasonably necessary to permit the specialist to maintain, as far as
practicable, a fair and orderly market in its specialist stocks. In addition,
the specialist must comply with the following trading requirements:

    - A specialist must first satisfy a customer's market buy order (an order to
      buy at the prevailing market price) before buying any stock for its own
      account. Similarly, a specialist must first satisfy a customer's market
      sell order (an order to sell at the prevailing market price) before
      selling any stock for its own account.

    - A specialist must first satisfy a customer's limit order held by it before
      buying or selling at the same price for its own account. A limit order is
      an order either to buy only at or below a specified price, or to sell only
      at or above a specified price. A specialist may not have priority over any
      customer's limit order. A specialist, however, may buy or sell at the same
      price as a customer limit order as long as that limit order is executed
      first.

    - If a public buyer wants to buy at a particular price and a seller wants to
      sell at the same price, the buyer and seller trade directly with each
      other, and the specialist should not interfere in the transaction.

    - The specialist does not charge commissions for trades in which it acts as
      a principal.

    - Except in some circumstances in less active markets, the specialist may
      not, without permission from an NYSE official, initiate destabilizing
      trades for its own account which cause the stock price to rise or fall.

    - Any transactions by the specialist for its own account must be effected in
      a reasonable and orderly manner in relation to the condition of the
      general market, the market in the particular stock and the adequacy of the
      specialist's position to the immediate and reasonably anticipated needs of
      the market.

    In addition, the specialist cannot be in a control relationship with any of
its listed companies. This means a specialist may not acquire more than 5% of
any common or preferred issue of its specialist stocks and may not own 10% or
more of any common or preferred stock. A specialist may not hold any position as
an officer or director or receive payments or loans or engage in business
transactions with any of its listed companies.

                                       27

RISK MANAGEMENT

    Because our specialist activities expose our capital to significant risks,
managing these risks is a constant priority for us. Our central role in the
auction process helps us to reduce risks by enabling us to incorporate
up-to-date market information in the management of our inventory, subject to our
specialist obligations. In addition, we have developed a risk management
process, which is designed to balance our ability to profit from our specialist
activities with our exposure to potential losses. Our risk management process
includes participation by our executive operating committee, our floor
management committee, our floor team captains and our specialists. These
parties' roles are described as follows:

    EXECUTIVE OPERATING COMMITTEE.  Our executive operating committee is
composed of Michael LaBranche, Anthony M. Corso, Alfred O. Hayward, Jr., Robert
M. Murphy and James G. Gallagher. This committee is responsible for approving
all risk management policies and trading guidelines for particular specialist
stocks, after receiving input and proposals by the floor management committee.
In addition, our executive operating committee reviews all unusual situations
reported to it by our floor management committee.

    FLOOR MANAGEMENT COMMITTEE.  Our floor management committee is composed of
Anthony M. Corso, Alfred O. Hayward, Jr., Robert M. Murphy, John McGraner,
Michael Nichols, Thomas McLaughlin and Gene McCarthy. This committee is
responsible for formulating and overseeing our overall risk management policies
and risk guidelines for each of our specialist stocks. In arriving at these
policies and guidelines, our floor management committee considers the advice and
input of our floor team captains. Our floor management committee meets with all
floor team captains no less than once a month to review and, if necessary,
revise the risk management policies for our company as a whole and/or for
particular specialist stocks. In addition, a member of our floor management
committee is always available on the trading floor to review and assist with any
unusual situations reported by a captain. Our floor management committee reports
to our executive operating committee about each of these situations.

    FLOOR TEAM CAPTAINS.  We have 13 floor team captains who monitor the
activities of our specialists throughout the trading day from various positions
at our trading posts. The captains observe trades and constantly review trading
positions in real-time through our information systems. In addition, the
captains are readily available to assist our specialists in determining when to
deviate from our policies and guidelines to react to any unusual situations or
market conditions. The captains must report these unusual situations to
management, including any deviations from our policies and guidelines. Captains
meet with each specialist at least once a week to evaluate the specialist's
adherence to our risk management policies and guidelines. Captains also meet
among themselves at least twice weekly to review risk policies and guidelines
and, if appropriate, make new recommendations to the floor management committee.

    SPECIALISTS.  Our specialists conduct auctions based upon the conditions of
the marketplace. In doing so, specialists observe our risk management policies
and guidelines as much as practicable. Specialists must immediately notify a
captain of any unusual situations or market conditions requiring a deviation
from our policies and guidelines.

    We rely heavily on our information systems in conducting our risk
management. Management members and captains must constantly monitor our
positions and transactions in order to mitigate our risks and identify
troublesome trends as they occur. We have invested substantial capital in
real-time, on-line systems which give management instant access to specific
trading information at any time during the trading day, including:

    - our aggregate long and short positions;

                                       28

    - the various positions of any one of our trading professionals;

    - our overall position in a particular stock;

    - capital and profit-and-loss information on an aggregate, per specialist or
      per issue basis; and

    - average position size.

    CIRCUIT BREAKER RULES.  The NYSE has instituted certain circuit breaker
rules intended to halt trading in all NYSE-listed stocks in the event of a
severe market decline. The circuit breaker rules impose temporary halts in
trading when the Dow Jones Industrial Average drops a certain number of points.
Effective January 2, 2001, circuit breaker levels are set quarterly at 10, 20
and 30 percent of the Dow Jones Industrial Average closing values of the
previous month, rounded to the nearest 50 points.

LISTED COMPANY SERVICES

    We are committed to providing our listed companies with a high level of
service, in addition to our specialist functions on the trading floor. We have a
Corporate Relations Department, consisting of 17 full-time employees and one
independent consultant devoted to serving our listed companies. The most
important function of the Corporate Relations Department is to provide current
information to the listed companies. Upon request, our Corporate Relations
Department provides our listed companies with the following reports:

    - daily reports on the trading results of their stock;

    - real-time data regarding intra-day trading activity in their stock; and

    - weekly, monthly and yearly reports which analyze short and long term
      trading trends in their stock.

    In addition to providing trading information, we help to educate our listed
companies on general market trends. We organize annual educational conferences
that review trends in the securities industry and NYSE trading. We also publish
for and distribute to our listed companies a periodic newsletter that reviews
market trends. Finally, we survey our specialist companies annually on the
quality of our services, and use the information obtained in these surveys to
continually improve our services.

DIRECT ACCESS BUSINESS

    The Institutional Client Group division of our LaBranche Financial
Services, Inc. subsidiary places its customers in direct contact with the NYSE.
Utilizing its easy-to-use web-based technology, this division provides
institutional customers with the choice of two conduits for sending their order
flow directly to the point of sale on the floor of the NYSE. Orders that require
special attention can be sent to one of this division's licensed floor brokers
for customized handling. Otherwise, the customer can send its orders directly to
the specialist's order book using the NYSE's Super-Dot system. This division's
brokers take advantage of the NYSE's advanced wireless technology to communicate
directly with its trading customers. By employing the advanced technology, its
customers receive extremely fast trade executions and confirmations. All
customer orders are treated with strict confidentiality and anonymity, allowing
for the best execution with the least market impact. In addition, this
division's customers are given all the benefits of straight-through, seamless
trade processing. LaBranche Financial Services also clears and delivers the
trades directly to its customers' depository accounts.

NYSE MEMBERSHIPS

    NYSE memberships are granted only to individuals, and each individual
specialist must own or lease a NYSE membership. As of December 31, 2001, we had
109 specialists, each of whom owned or leased a membership under the following
arrangements:

    - 10 memberships were owned directly by 10 of our employees;


    - 33 were owned by specialists, who acquired their memberships through
      financing provided by us pursuant to so-called A-B-C agreements; and


    - 66 were leased by us from other individual members and we pay and
      guarantee the lease payments.


    Furthermore, our LaBranche Financial Services, Inc. subsidiary has financed
the acquisition of two memberships which are available for use by its employees
and two of its other employees directly own and use two additional memberships.
LaBranche & Co. LLC also has financed the acquisition of three other memberships
which are used by its employees, and two of its other employees lease seats that
are available for use by LaBranche & Co. LLC specialists.


AMEX SPECIALIST UNIT

    In December 2000, we purchased the assets and operations of an AMEX options
specialist unit and, in August 2001, we expanded our AMEX specialist activities
by purchasing the assets and operations of another AMEX specialist firm,
Cranmer & Cranmer, Inc. Our AMEX specialist business is conducted by our
LaBranche & Co. LLC subsidiary. This unit acts as the specialist in 57 stocks
and 122 options. We believe that these acquisitions enhance our commitment to
the listed auction market and are important steps in the implementation of our
growth strategy. As of December 31, 2001, the nine AMEX memberships utilized by
this specialist unit were leased by eight specialist employees of that unit,
while one membership was owned directly by an employee. LaBranche & Co. LLC pays
and guarantees the rental payments due under these leases.

OUR INFORMATION AND COMMUNICATIONS SYSTEMS AND THE NYSE SUPER-DOT SYSTEM

    As a self-clearing broker-dealer, we have made significant investments in
our trade processing systems. Our use of and dependence on technology have
allowed us to maintain our significant growth over the past several years. In
addition to using consultants who primarily service the specialist industry, we
have an in-house information technology staff. We currently clear an average of
about 110,000 principal trades per day. Our information systems send and receive
data from the NYSE through a dedicated data feed.

    Our systems enable us to monitor, on a real-time basis, our profits and
losses along with our trading positions. The NYSE supplies us with specialist
position reporting system terminals both on the trading floor and in our
offices. These terminals allow us to monitor our trading profits and losses as
well as our positions.

    We have a back-up disaster recovery center in New Jersey. The back-up system
operates as a mirror image of our primary computer system in New York City as we
have a direct connection between the two sites which we utilize to back-up all
data on an hourly basis. We also test both systems on a regular basis to assure
that they are fully operational.

    In executing trades on the NYSE, we receive electronic orders from the
Super-DOT system, an order routing system operated by the NYSE. The Super-DOT
System is designed to handle individual orders of up to 100,000 shares and is
essentially an electronic broker. Orders that originate through the Super-DOT
system are routed directly to us through our computer system at the NYSE. When
we receive an order from the Super-DOT system, we conduct the same auction
process and we are subject to the same obligations as with any other order.

    Our information technology staff has developed software which enables our
corporate relations staff and our specialists to share information with each
other regarding upcoming company and

                                       30

industry conferences. In addition, we monitor each of our specialist stocks
intra-day to see if there are any significant price and/or volume variances of
which we should alert the listed company. This has proven to be a valuable
customer service tool.

OUR PROPRIETARY TRADING

    In 1995, we initiated a proprietary trading program, seeking to leverage our
trading and market experience. Our strategy is short-term oriented, and most of
our positions are intra-day and not held overnight. Our five traders focus
primarily on stocks listed on the NYSE. In 2001, we derived 0.3% of our revenues
from our proprietary trading. Our proprietary trading desk utilizes a Windows NT
based trade reporting system which captures all trades executed by the trading
desk and marks all positions to market. We are not permitted to trade in stocks
for which we act as specialist.

    We have taken the following actions to manage the risks associated with our
proprietary trading:

    - for 2001, we limited our capital commitment for our individual proprietary
      traders to an aggregate maximum of $24.8 million intra-day and overnight
      positions of up to $17.8 million per day; and

    - each of our proprietary traders has specific trading limits, which may not
      be exceeded without the approval of executive management. Our most
      experienced trader may invest up to $12.0 million per day and may hold
      overnight positions up to $7.5 million. Each of our other traders has
      daily investment limits of $5.0 million or less and overnight investment
      limits of $3.2 million or less, depending on his experience.

MARKETING

    It is a priority for our management to proactively identify potential
listing companies before the allocation process begins. We contact these
companies and commence our marketing efforts upon determining that they are
considering listing on the NYSE. Our marketing efforts typically consist of
members of our management group visiting with the companies that are considering
listing on the NYSE and describing our services. We also provide written
literature describing our operations, our listed companies, our more than
75-year history as a specialist firm and our industry in general.

REGULATORY MATTERS

  GENERAL

    The securities industry in the United States, including all broker-dealers,
is subject to extensive regulation under both federal and state laws. In
addition, the SEC, the NYSE and the AMEX require strict compliance with their
rules and regulations. As a matter of public policy, regulatory bodies are
charged with safeguarding the integrity of the securities and other financial
markets and with protecting the interests of investors participating in those
markets.

    As two of our subsidiaries are broker-dealers, we are subject to regulations
concerning operational and financial aspects of our business. We are subject to
extensive registration requirements with various government entities and
self-regulatory organizations, commonly referred to as SROs, with which we must
comply before we can conduct our business. We are also subject to laws, rules
and regulations forcing us to comply with financial reporting requirements,
trade practices, capital structure requirements, and record retention
requirements governing the conduct of our directors, officers and employees.
Failure to comply with any of these laws, rules or regulations could result in
censure, fine, the issuance of cease-and-desist orders or the suspension or
disqualification of our directors, officers or employees, and other adverse
consequences, which could have an adverse effect on our business.

    As a NYSE specialist firm, we are under constant review by the NYSE on all
aspects of our operations and financial condition. As part of the price
discovery mechanism implemented by the NYSE, every specialist transaction is
published immediately on the tape and is broadcast worldwide. The NYSE also
employs sophisticated monitoring and stringent rules approved by the SEC. The

                                       31

NYSE's Market Surveillance Division examines specialists' trading in all stocks,
every trading day, including specialists' decisions to trade or to not trade as
principal.

  CAPITAL REQUIREMENTS

    As a NYSE specialist and broker-dealer, we are subject to SEC Rule 15c3-1,
which requires minimum net regulatory capital. We are required to maintain
minimum net capital, as defined, equivalent to the greater of $100,000 or 1/15
of our aggregate indebtedness, as defined. At December 31, 2001, our net
capital, as defined by this rule, was $484.2 million and exceeded minimum
requirements by $481.4 million.

    The NYSE also requires members registered as specialists to maintain a
minimum regulatory capital dollar amount to establish that they can meet, with
their own net liquid assets, their position requirement. Under changes to
Rule 104, effective October 30, 2000, the NYSE's minimum net liquid asset
requirements, specialist units that exceed five percent in any of the NYSE's
four concentration measures must maintain minimum net liquid assets based upon
the securities for which they act as the specialist. The requirements state that
the net liquid assets must be equivalent to $4.0 million for each stock in the
Dow Jones Industrial Average, $2.0 million for each stock in the S&P 100 Stock
Price Index, excluding stocks included in the previous classification,
$1.0 million for each stock in the S&P 500 Stock Price Index, excluding stocks
included in the previous classification, $500,000 for each common stock,
excluding bond funds and stocks included in the previous classifications, and
$100,000 for each stock not included in any of the above classifications. In
addition, the NYSE requires any new specialist entities that result from a
merger, acquisition, consolidation or other combination of specialist entities
to maintain net liquid assets equivalent to the greater of either (1) the
aggregate net liquid assets of the specialist entities prior to their
combination or (2) the new capital requirements prescribed under Rule 104.
LaBranche & Co. LLC's net liquid asset requirement was $446.0 million as of
December 31, 2001, and it actually had net liquid assets of $491.5 million. "Net
liquid assets" for a specialist firm that also engages in transactions other
than specialist activities is based upon its excess net capital as determined in
accordance with SEC Rule 15c3-1.


    As registered broker-dealers and NYSE member firms, our former subsidiaries,
Henderson Brothers Inc. and ROBB PECK McCOOEY Clearing Corporation were also
subject to SEC Rule 15c3-1, as adopted and administered by the NYSE. Under the
alternative method permitted by the rule, the minimum required net capital for
each subsidiary as of December 31, 2001 was equal to the greater of $250,000 or
2% of aggregate debit items, as defined. As of December 31, 2001, Henderson
Brothers Inc.'s and ROBB PECK McCOOEY Clearing Corporation's combined net
capital as defined under SEC Rule 15c3-1 was $20.5 million and exceeded minimum
requirements by $19.7 million.


    Effective as of the close of business on December 31, 2001, Henderson
Brothers, Inc. and Internet Trading Technologies, Inc., another former
subsidiary, merged with and into ROBB PECK McCOOEY Clearing Corporation, which
then changed its name to LaBranche Financial Services, Inc. and continues to be
a registered broker-dealer and NYSE member firm.

    Failure to maintain the required net capital and net liquid assets may
subject us to suspension or revocation of SEC registration or suspension or
expulsion by the NYSE.

COMPETITION

    We obtain each of our new listings on the NYSE by participating in an
allocation process. As part of this process, either the allocation committee of
the NYSE or the listing company chooses the specialist firm. We compete with
other specialist firms based on a number of factors, including:

    - the strength of our capital base;

    - our willingness to commit our own capital and trade for our own account
      while conducting our specialist operations; and

                                       32

    - the ancillary services we offer our specialist companies, such as
      providing information on the trading activities in their stocks.

    The following is a list of the remaining specialist units as of
December 31, 2001, listed in order of their number of common stock listings:

    - LaBranche & Co. LLC

    - Spear Leeds & Kellogg Specialist

    - Fleet Meehan Specialist, Inc.

    - Wagner Stott Bear Specialists, LLC

    - Van Der Moolen Specialists USA

    - Performance Specialist Group, LLC

    - Susquehanna Specialists, Inc.

    - Lyden Dolan Nick & Co. LLC (in the process of being acquired by Van Der
      Moolen Specialists USA)

    - Walter N. Frank & Co. LLC

    The competition for obtaining new listed companies is intense. We expect
competition to continue and intensify in the future. Some of our competitors may
have significantly greater financial resources than we have and may also have
greater name recognition. These competitors may be able to respond more quickly
to new or evolving opportunities and listed company requirements. They may also
be able to undertake more extensive promotional activities to attract new
listing companies. In addition, the specialist industry has recently been
consolidating. The combined companies resulting from the consolidation may have
a stronger capital position. This trend has intensified the competition in our
industry. We cannot be sure that we will be able to compete effectively with our
current or future competitors. We also cannot be sure that the competitive
pressures we face will not have an adverse effect on our business, financial
condition and/or operating results.

EMPLOYEES

    As of December 31, 2001, we had 545 full-time employees, including 53
managing directors, with:

    - 118 specialists, including 47 managing directors and nine AMEX options
      specialists;

    - 244 trading assistants;

    - 17 corporate relations department employees;

    - 54 clearing operations employees; and

    - 112 management, administration and finance staff, including six managing
      directors.

    Our employees are not covered by a collective bargaining agreement. We have
never experienced an employment-related work stoppage. We consider our employee
relations to be good.

PROPERTIES

    Our corporate offices are located at One Exchange Plaza, New York, New York.
We lease about 36,000 square feet under four separate leases, expiring in
January 2008. We also lease about 45,000 square feet at 120 Broadway, New York,
New York, expiring in March 2008. In addition, we lease four trading posts on
the floor of the NYSE. We believe that our current leased space is suitable and
adequate for the operation of our business as presently conducted and as
contemplated to be conducted in the immediate future.

LEGAL PROCEEDINGS

    We are not a party to any material legal proceeding.

                              SELLING STOCKHOLDERS

    The following table identifies the selling stockholders and sets forth
information with respect to their beneficial ownership of our common stock.

    As of December 31, 2001, 58,733,955 shares of our common stock were
outstanding. The amounts and percentages of common stock beneficially owned are
reported on the basis of regulations of the SEC governing the determination of
beneficial ownership of securities. Under the rules of the SEC, a person is
deemed to be a "beneficial owner" of a security if that person has or shares
"voting power," which includes the power to vote or to direct the voting of the
security, or "investment power," which includes the power to dispose of or to
direct the disposition of the security. A person is also deemed to be a
beneficial owner of any securities of which that person may be deemed a
beneficial owner within 60 days. Under these rules, more than one person may be
deemed a beneficial owner of the same securities and a person may be deemed to
be a beneficial owner of securities as to which the person has no economic
interest.

    The selling stockholders are some of our managing directors who obtained the
shares of our common stock to which this prospectus relates in connection with
our reorganization from partnership to corporate form prior to the initial
public offering of our common stock in August 1999.

    The selling stockholders will enter into prepaid forward contracts pursuant
to which DECS Trust IX will agree to purchase the shares of our common stock
covered by this prospectus from the selling stockholders on or about the third
anniversary of the date of the contracts. DECS Trust IX will publicly offer DECS
securities, which will represent the rights of investors to receive shares of
the selling stockholders' common stock upon termination of DECS Trust IX. The
selling stockholders will remain the beneficial owners of the shares of our
common stock covered by the prepaid forward contracts unless and until the
selling stockholders elect or are required to deliver the shares to the trust
pursuant to the prepaid forward contracts. You should read the prospectus of
DECS Trust IX for a description of, among other things, the prepaid forward
contracts and the DECS securities. The information in the

                                       36

table assumes that the underwriters will not exercise their right to purchase
additional DECS securities in the offering of the DECS securities.

    The selling stockholders are party to a stockholders' agreement under which
they have agreed to a number of restrictions on ownership and transfer of our
common stock. Pursuant to the stockholders' agreement, one-third of the selling
stockholders' shares are not eligible to be sold until August 24, 2002. An
additional one-third are not eligible to be sold until August 24, 2003 and the
remaining one-third are not eligible to be sold until August 24, 2004. We have
agreed to waive these transfer restrictions in order to enable the selling
stockholders to offer and sell the shares of common stock represented by this
prospectus.



    In addition, notwithstanding the restrictions described above, each selling
stockholder agreed that for so long as he or she remains in the employ of us or
any of our subsidiaries, he or she must at all times be the sole beneficial
owner of 25% or more of the aggregate number of shares of common stock
(1) beneficially owned by that selling stockholder on August 24, 1999 and

                              PLAN OF DISTRIBUTION

    Under the prepaid forward contracts, DECS Trust IX has agreed, subject to
the terms and conditions set forth in those contracts, to purchase from the
selling stockholders named in this prospectus a number of shares of our common
stock equal to the total number of DECS securities to be purchased by the
underwriters from the trust under an underwriting agreement (including any DECS
securities to be purchased by the underwriters upon exercise of an
over-allotment option plus the number of DECS securities purchased by Salomon
Smith Barney Inc., who sponsored the formation of the trust, in connection with
the organization of the trust) among Salomon Smith Barney Inc., ABN AMRO
Rothschild LLC, Jefferies & Company, Inc., the trust, the selling stockholders
and us. Under the terms of the prepaid forward contracts, each selling
stockholder is obligated to deliver to the trust on February   , 2005 (or such
later date elected by the selling stockholders) a number of shares of our common
stock (or, at the option of the selling stockholders, the cash equivalent of
those shares) and/or any other consideration permitted or required by the terms
of the prepaid forward contracts, that are expected to have the same value as
the shares of our common stock to be delivered under the DECS securities.

    In connection with the DECS securities offering, the underwriters may
over-allot, or engage in syndicate covering transactions, stabilizing
transactions and penalty bids. Over-allotment involves syndicate sales of DECS
securities or our common stock in excess of the number of DECS securities to be
purchased by the underwriters in this offering, which creates a syndicate short
position. Syndicate covering transactions involve purchases of the DECS
securities or our common stock in the open market after the distribution has
been completed in order to cover syndicate short positions. Stabilizing
transactions consist of certain bids or purchases of DECS securities or our
common stock made for the purpose of preventing or retarding a decline in the
market price of the DECS securities or our common stock while the offering is in
progress. Penalty bids permit the underwriters to reclaim a selling concession
from a syndicate member when one of the underwriters, in covering syndicate
short positions or making stabilizing purchases, repurchases DECS securities or
our common stock originally sold by the syndicate member. These activities may
cause the price of DECS securities or our common stock to be higher than the
price that otherwise would exist in the open market in the absence of these
transactions. These transactions may be effected on the NYSE or in the
over-the-counter market, or otherwise and, if commenced, may be discontinued at
any time.


    The expenses of the DECS securities offering, not including the underwriting
discount, are estimated at $      , certain of which are payable by the selling
stockholders.


    We and the selling stockholders have agreed to indemnify the underwriters
against certain liabilities, including liabilities under the Securities Act, or
to contribute to payments the underwriters may be required to make in respect of
those liabilities.

OTHER RELATIONSHIPS


    Salomon Smith Barney Inc., ABN AMRO Incorporated and Jefferies & Company,
Inc. acted as underwriters in the initial public offering of our common stock in
August 1999. Salomon Smith Barney Inc. and ABN AMRO Incorporated acted as
initial purchasers in our public debt offerings. All three are acting as
underwriters in the concurrent offering of the DECS securities of DECS Trust IX.
We act as specialist for the American Depositary Receipts and preferred stock of
ABN Amro Holding N.V. and for the common stock of Jefferies Group, Inc., all of
which are traded on the NYSE.


NO SALES OF SIMILAR SECURITIES


    We and certain of our executive officers and directors have agreed, with
exceptions, not to offer, sell, contract to sell or otherwise dispose of, or
transfer, any of our common stock or warrants, rights, options or other
securities convertible into or exchangeable for LaBranche common stock for
90 days


                                       39


after the effective date of the registration statement of which this prospectus
forms a part without first obtaining the written consent of Salomon Smith Barney
Inc. and us. George E. Robb, Jr., one of our directors, has instituted a 10b5-1
sale program pursuant to which he has designated up to 100,000 shares of our
common stock to be sold when certain stock price targets are met.


    The agreement described above will not restrict our ability or the ability
of the selling stockholders to take any of the actions listed above in
connection with the offering by the trust of the DECS securities or any delivery
of shares of our common stock under the terms of the prepaid forward contracts.

ITEM 17. UNDERTAKINGS

    (a) The undersigned Registrant hereby undertakes:

       (1) To file, during any period in which offers or sales are being made, a
           post-effective amendment to this registration statement to include
           any material information with respect to the plan of distribution not
           previously disclosed in the registration statement or any material
           change to such information in the registration statement;

       (2) That, for the purpose of determining any liability under the
           Securities Act of 1933, each such post-effective amendment shall be
           deemed to be a new registration statement relating to the securities
           offered therein, and the offering of such securities at that time
           shall be deemed to be the initial bona fide offering thereof;

       (3) To remove from registration by means of a post-effective amendment
           any of the securities being registered which remain unsold at the
           termination of the offering.

    (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

    (c) Insofar as indemnification for liabilities 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 a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
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 of the Registrant 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.

                                      II-2

                                   SIGNATURES


    Pursuant to the requirements of the Securities Act of 1933, the registrant

Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in The City of New York, State of New York, on the 23rd day of
January, 2002.
