Item 1. BUSINESS.

Overview

      Founded in 1924, our specialist LaBranche & Co. is one of the oldest and
largest specialist firms on the New York Stock Exchange ("NYSE"). As a NYSE
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 increased from approximately $37.1 million in 1995 to $201.0 million in
1999, representing a compound annual growth rate of 52.6%. 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,
as described in "Industry Background--The Specialist", we were selected by 53
new listed companies, resulting from 83 listing interviews. In addition we have
acquired five specialist operations since 1997, adding 278 new common stock
listings to our firm. During the past five years, we have also increased the
scope of our business, as illustrated by the following data obtained from the
NYSE:

      o     the annual dollar volume on the NYSE of stocks for which we acted as
            specialist increased to $1.2 trillion in 1999, as compared to $133.3
            billion in 1995. Based on these dollar volumes, we were the second
            largest specialist firm in 1999 as compared to the eighth largest in
            1995;

      o     the annual share volume on the NYSE of stocks for which we act as
            specialist increased to 25.7 billion in 1999, as compared to 4.0
            billion in 1995. Based on these share volumes, we were the second
            largest specialist firm in 1999 as compared to the sixth largest in
            1995; and


                                       1
<PAGE>

      o     the total number of our common stock listings increased to 271 as of
            December 31, 1999, as compared to 125 as of December 31, 1995. Based
            on the number of our common stock listings, we were the third
            largest specialist firm as of December 31, 1999 as compared to the
            fifth largest as of December 31, 1995. In addition, we acted as
            specialist for 89 other listed securities.

      On March 2, 2000 we completed our acquisition of Henderson Brothers
Holdings, Inc. ("Henderson Brothers"), which in turn wholly owns Henderson
Brothers Inc., a specialist on the NYSE. Established in 1861, Henderson Brothers
first registered as a NYSE specialist in 1948 and was the eighth largest
specialist firm on the NYSE in terms of common stock listings at year end 1999.
Henderson Brothers acted as specialist in 113 common stock listings, including
26 companies in the S&P 500 and two companies included in the Dow Jones
Industrial Average. These listings include American Express Company, Ford Motor
Company, J.P. Morgan & Co., Lehman Brothers Holdings, Inc., Morgan Stanley Dean
Witter & Co. and Schering-Plough Corporation. Henderson Brothers had $82.1
million of revenues and $29.1 million of EBITDA for the year ended 1999.

      On March 9, 2000 we also acquired, through a merger, Webco Securities,
Inc. ("Webco"), another specialist firm on the NYSE. Established in 1981, Webco
acted as specialist in 34 common stock listings, including First Union
Corporation, Manor Care, Inc. and Nokia Corporation. Webco had $13.7 million of
revenues and $4.2 million of EBITDA for the year ended October 31, 1999.

      As of March 24, 2000, our listed companies include:

      o     75 of the S&P 500 companies; and

      o     seven of the 30 companies comprising the Dow Jones Industrial
            Average. Our seven Dow stocks are American Express, AT&T,
            ExxonMobil, JP Morgan, Merck, Minnesota Mining & Manufacturing 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
approximately $6.0 trillion at December 31, 1995 to approximately $10.1 trillion
at December 31, 1999, representing a compound annual growth rate of 13.9%. The
number of companies listed on the NYSE increased from 2,675 at the end of 1995
to 3,025 at the end of 1999.

      The NYSE's average daily trading volume increased from 91.2 million shares
in 1984 to 809.2 million shares in 1999, 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 approximately $2.0
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
commission. Independent floor brokers are brokers who independently handle
orders for other broker-dealers and financial institutions.

The 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, many of which are
organized as private partnerships, has decreased from 36 at December 31, 1995 to
25 at December 31, 1999. Of these, the three largest specialist units as ranked
by their number of specialist stocks were responsible for approximately 47.4% of
the average daily trading volume (measured by dollar volume) in 1999.

      A specialist firm is granted the franchise by the NYSE in a particular
stock to conduct the auction in that security. 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 a specialist firm. Currently, substantially all of the companies seeking
a listing on the NYSE are opting 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


                                       3
<PAGE>

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:

      o     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;

      o     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;

      o     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

      o     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 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 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:

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

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

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


                                       4
<PAGE>

      o     an increase in NYSE-listed stocks due to:

            o     IPOs and spin-offs;

            o     transfers from Nasdaq and the American Stock Exchange; and

            o     an increase in listings of foreign companies;

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

      o     an increase in on-line trading;

      o     trading in smaller price increments;

      o     an increase in the market capitalization of growth stocks; and

      o     an increase in the amount of shares traded due to stock splits and
            stock dividends.

These factors have, in turn, been influenced by a strong U.S. economy, low
interest rates and low levels of inflation.

      The NYSE has announced that it will implement a pilot program for trading
in decimals in July 2000 and has increased the window for providing
commission-free execution of a trade to five minutes (from the current two
minutes). The NYSE is also considering the following additional changes:

      o     longer trading days; and

      o     trading of foreign stocks in ordinary form side by side with their
            American depository receipts (ADRs).

These additional changes are being considered for implementation within the next
18 months. 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 1999, specialist firms handled approximately 82.5% of
trades in NYSE-listed stocks. Trades in NYSE-listed stocks are also generally
effected as follows:

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

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


                                       5
<PAGE>

      o     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 (ATSs), such as electronic communications networks
(ECNs) and crossing systems. 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 are being 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 82.1% to 84.1% 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 greater capital, better access to technology and direct
access to investors. As a result, these parties may be well positioned to direct
trading to these networks. These alternative trading methods may account for a
growing percentage of the trading volume of NYSE-listed stocks.

      The accelerating growth of trading volume and the increase in stock prices
on the NYSE in the 1990s has 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 specialist market is becoming
increasingly dominated by a number of large, better-capitalized specialist firms
which 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:

      o     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. As of December 31, 1999
            trading in the stocks for which we acted as specialist during 1999
            accounted for 14.5% of the dollar volume on the NYSE and 13.5% of
            the share volume. Based on these percentages, we were the second
            largest specialist firm on the NYSE. We are continuing to develop
            our relationships with ATSs and to embrace new technologies in
            trading platforms.

      o     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


                                       6
<PAGE>

            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.

      o     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 1999,
            approximately 32.0% of our trades were as principal as compared to
            an average of approximately 26.4% for all NYSE specialists.

      o     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:

            o     host an annual listed company conference;

            o     publish a company newsletter; and

            o     commission customer satisfaction surveys from our listed
                  companies.

      o     Completed Acquisitions. Since 1997, we have acquired the following
            five specialist operations, solidifying our position as one of the
            leading NYSE specialist firms:

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

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

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

            o     Henderson Brothers, Inc. (March 2000); and

            o     Webco Securities, Inc. (March 2000).

      We have effectively employed our capital resources and skilled personnel
to maximize the synergies created through consolidation. In doing so, we have
succeeded in growing each of our earlier acquired operations and enhancing their
profitability. We believe this experience will assist us in integrating the
businesses of our recent acquisitions, Henderson Brothers and Webco.

Recent Acquisitions

Henderson Brothers

      On March 2, 2000, we acquired Henderson Brothers, which owns Henderson
Brothers, Inc., a


                                       7
<PAGE>

specialist firm on the NYSE, and Henderson Brothers Futures Corporation, an
inactive subsidiary. Under the terms of the agreement, we acquired all the
outstanding capital stock of Henderson Brothers for approximately $230.0 million
in cash. The proceeds of our Senior Subordinated Note Offering were used to
fully fund the acquisition of Henderson Brothers, to partially fund the
acquisition of Webco and to pay fees and expenses related to both acquisitions.
As part of the Henderson Brothers acquisition, we entered into employment
agreements with 14 specialists and an additional employee formerly employed by
Henderson Brothers. We also entered into consulting agreements with two former
Henderson Brothers employees pursuant to which we are paying an aggregate of
$5.0 million over five years.

      In connection with the Henderson Brothers acquisition, we:

      o     acquired an additional 19 NYSE memberships, all of which are owned
            by the individual specialists but are financed by LaBranche & Co.;

      o     hired an additional 84 employees, 19 of which are specialists, 41 of
            which are specialist trading assistants and 24 of which are other
            administrative, financial and operational personnel; and

      o     acquired an additional 8,650 feet of office space, which had a
            $216,726 annual lease payment in 1999.

      In addition, as part of the acquisition, we also acquired and are
continuing the clearing operations of Henderson Brothers. As a clearing broker,
we are responsible for the clearance and settlement of transactions effected by
us or the introducing broker. We only clear and settle transactions executed by
the introducing brokers; we do not execute these transactions.

Webco

      On March 9, 2000, we acquired, through a merger, another specialist firm
on the NYSE, for 2.8 million shares of our common stock, $10.9 million in cash
and senior promissory notes in the aggregate principal amount of $3.0 million,
each bearing an interest rate of 10.0% per annum. As part of the acquisition, we
entered into employment agreements with three specialists employed by Webco.

      In connection with to the Webco acquisition, we:

      o     acquired an additional 3 NYSE memberships;

      o     hired an additional 14 employees, 5 of which are specialists, 8 of
            which are specialist trading assistants and one of which performs
            administrative functions; and

      o     acquired an additional 2,057 feet of office space, which had a
            $51,425 annual lease payment in 1999.

      Following the completion of the acquisitions of Henderson Brothers and
Webco, we are the largest specialist firm on the NYSE in terms of the annual
dollar and share volume traded. We are the specialist for 413 common stock
listings, including 75 of the S&P 500 and seven companies included in the Dow
Jones Industrial Average.


                                       8
<PAGE>

      Simultaneously with the acquisitions of Henderson Brothers and Webco, we
transferred the specialist operations of each of Henderson Brothers and Webco to
our subsidiary LaBranche & Co. The clearing operations of Henderson Brothers are
operated by us as a separate subsidiary.

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.

      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 3/4, and the best public offer (to
      sell) on the book is $50 1/4. A broker who wants to buy 100 shares at the
      market in this instance without a specialist would purchase at $50 1/4,
      the offer price. Similarly, a broker seeking to sell 100 shares without a
      specialist would receive $49 3/4, 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
      1/16 from the specialist, as opposed to buying the same amount of shares
      from the best offer of $50 1/4, 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 3/4, 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:

      o     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


                                       9
<PAGE>

      selling any stock for its own account.

      o     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.

      o     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.

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

      o     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.

      o     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.

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 as participants 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, Vincent J. Flaherty, Alfred O. Hayward, Jr., Michael J.
Naughton, James G. Gallagher, Harvey S. Traison and John O. Pickett. 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.


                                       10
<PAGE>

Floor Management Committee. Our floor management committee is composed of
Messrs. Flaherty Hayward, Naughton, Gallagher and Pickett. 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 ten 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 should 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:

      o     our aggregate long and short positions;

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

      o     our overall position in a particular stock;

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

      o     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. 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 seven 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:

      o     daily reports on the trading results of their stock;

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

      o     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.

NYSE Memberships

      NYSE memberships are granted only to individuals, and each individual
specialist must own or lease a NYSE membership. As of December 31, 1999, we had
48 specialists. As of March 24, 2000, we had 73 specialists, each of whom owned
or leased a membership under the following arrangements:

      o     10 memberships were owned directly by 10 of our specialists;

      o     26 were owned by specialists and financed by LaBranche & Co.; and

      o     37 were leased by 35 of our specialists from other individual
            members, and we pay and guarantee the lease payments.

Our Information and Communications Systems and the NYSE's 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
approximately 60,000 principal trades per day. We have continued the clearing
operations of Henderson Brothers, which included limited clearing of trades for
third parties. Our information systems send and receive data from the NYSE
through a dedicated data feed.


                                       12
<PAGE>

      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 also developed software that allows us to monitor
these items in the event that the NYSE-provided systems fail.

      We have a back-up disaster recovery center in Hoboken, NJ. 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. On a regular basis, we test both systems 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 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. Four of our traders focus
primarily on stocks listed on the NYSE. A fifth trader focuses entirely on
listed futures and options on both United States Treasury obligations and
Eurodollars. In 1999, we derived 3.3% 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:

      o     for 2000, we have limited our capital commitment for our proprietary
            trading to an aggregate maximum of $19.5 million intra-day and
            overnight positions of up to $12.0 million per day;

      o     each of our proprietary traders have 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 have daily investment limits of $5.0 million or less
            and overnight investment limits of $3.0 million or less, depending
            on their experience;

      o     the positions of our futures and options traders are monitored by an
            in-house model that


                                       13
<PAGE>

      measures potential intra-day risk as well as actual dollar exposure; and

      o     one of our managing directors oversees all of our proprietary
            trading and has the authority to instruct the proprietary trading
            desk to liquidate positions or otherwise reduce risk. He reports
            directly to Michael LaBranche, our Chairman, Chief Executive Officer
            and President.

Specialist Companies

      As of December 31, 1999, we acted as specialist for 271 common stocks
listed on the NYSE. As of March 24, 2000, subsequent to our recent acquisitions,
we acted as specialist for 413 common stock listings. Our listed companies
operate in a variety of industries including financial services, media, oil and
gas, retail, technology and telecommunications. They ranged in market
capitalization from some of the smallest on the NYSE to some of its largest and
well-known corporations. We also represented 42 foreign listings on the NYSE as
of December 31, 1999 and 54 foreign listings as of March 24, 2000. The following
is a list of our top 50 listed companies in terms of market capitalization as of
March 24, 2000 in order of their respective global market capitalization (read

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 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 and the NYSE 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 a broker-dealer, 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
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 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, 1999, our net capital, as defined by
this rule, was approximately $161.4 million and exceeded minimum requirements by
approximately $159.9 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. During November 1999,
subject to SEC approval, the NYSE approved changes to Rule 104, its minimum


                                       15
<PAGE>

net liquid asset requirements. These changes required specialist units that
currently exceed five percent in any of the NYSE's four concentration measures
to 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,
$500,00 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 has proposed to require any new
specialist entities that result from a merger, acquisition, consolidation or
other combination of specialist assets 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. After the completion of our recent acquisitions of
Henderson Brothers and Webco, the net liquid asset requirement for our combined
entity is $284.3 million, which represents the combined net liquid assets of the
three firms. "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 of December 31,
1999, our NYSE minimum required dollar amount of net liquid assets was $93.6
million compared to actual net liquid assets of approximately $175.9 million.

      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:

      o     the strength of our capital base;

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

      o     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 top ten specialist units as of December 31,
1999, based on their number of common stock listings:

      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.

      NYSE-listed stocks may be traded:

      o     by NYSE members over-the-counter; and

      o     by non-NYSE members over-the-counter.

      Technological advances have also contributed to the recent emergence of
trading through alternative trading systems, such as electronic communication
networks and crossing systems. In April 1999, the SEC ruled that alternative
trading systems can apply and, in specified cases, are required to register as
stock exchanges, subject to regulation as a stock exchange. This would enable
NYSE members to trade all NYSE-listed stocks on these networks, regardless of
when the stocks were originally listed. These networks may be developed,
organized and operated by large brokerage houses and investment banks with
greater capital, better access to technology and direct access to investors. As
a result, these parties may be well-positioned to direct trading to these
networks. These alternative trading systems may adversely affect the trading of
NYSE-listed stock through specialists on the NYSE. That, in turn, would have an
adverse effect on our business.

      The NYSE faces competition from Nasdaq for new listings. Nasdaq continues
to grow and gain in popularity, attracting companies which might otherwise have
listed on the NYSE. In recent years in particular, many high technology
companies have opted to be quoted on Nasdaq, even though many of them would have
qualified for NYSE listing. If more companies decide to be quoted on Nasdaq as
opposed to listing their stocks on the NYSE, trading volume on the NYSE could be
adversely affected.

Employees

      As of December 31, 1999, we had 166 full-time employees, including 34
managing directors. As of March 24, 2000 we have 259 full-time employees,
including 46 managing directors with:

      o     73 specialists, including managing directors;

      o     6 traders in our proprietary trading department;

      o     143 trading assistants;

      o     7 Corporate Relations Department employees; and

      o     30 management, administration and finance staff, including 2
            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.

Item 2. PROPERTIES.

      Our offices are located at One Exchange Plaza, New York, New York. We
lease approximately 43,000 square feet under three separate leases, expiring in
October 2001, December 2002 and January 2008. In addition, we lease three
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.

Item 3. LEGAL PROCEEDINGS.

      We are not a party to any material legal proceeding.

Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

      There were no matters submitted to a vote of security holders during the

Market Information and Holders

      Our common stock is quoted on the NYSE under the symbol "LAB." The
following table sets forth the range of high and low sales prices for our common

         Fourth Quarter
            (October 1, 1999 to December 31, 1999)      $13.5000         $9.0625

      As of March 24, 2000, we had 116 stockholders of record of our common
stock and an estimated 1,800 beneficial owners. The closing sale price of our
common stock on March 24, 2000 was $14.00 per share.

Dividend Policy

      We have never paid cash dividends. We do not expect to declare or pay any
dividends on our common stock in the foreseeable future, but instead intend to
retain all earnings, if any, to invest in our operations. The payment of future
dividends is within the discretion of our board of directors and will depend
upon our future earnings, if any, our capital requirements, financial condition
and other relevant factors.

Recent Sales of Unregistered Securities

      In August 1999, concurrently with our initial public offering, we effected
the reorganization of our firm from partnership to corporate form. In connection
with this reorganization, we issued an aggregate of 35,375,000 shares of our
common stock to a majority of the limited partners of LaBranche & Co., a limited
partnership and our principal operating subsidiary, and the members of LaB
Investing Co. L.L.C., the general partner of LaBranche & Co., as partial
consideration in exchange for their limited partnership interests in LaBranche &
Co. and their membership interests in LaB Investing Co. L.L.C., respectively.
Our issuance of these securities was not registered under the Securities Act of
1933, as amended (the "Securities Act"), because these securities were offered
and sold in transactions exempt from registration under the Securities Act
pursuant to Section 4(2) of the Securities Act.

      Immediately prior to our initial public offering, we awarded options to
purchase our common stock and restricted stock units to various directors,
officers and other employees and will continue to do so from time to time. The
issuance of these employee awards has not been and will not be registered under
the Securities Act because these awards will not involve an offer or sale for
purposes of Section 2(a)(3) of the Securities Act.

Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.

      You should read the following discussion of our financial condition and
results of operations together with the financial statements and the notes to
such statements included elsewhere in this filing. This discussion contains
forward-looking statements based on our current expectations, assumptions,
estimates and projections about us and our industry. These forward-looking
statements involve risks and uncertainties including, but not limited to those
discussed in "Risk Factors" attached hereto as Exhibit 99.1. Our actual results
could differ materially from those anticipated in these forward-looking
statements as a result of certain factors. We undertake no obligation to update
publicly any forward-looking statements for any reason, even if new information
becomes available or other events occur in the future.

Overview

      Founded in 1924, our specialist LaBranche & Co. is one of the oldest and
largest specialist firms on the New York Stock Exchange, Inc. Our business has
grown considerably during the past five years. We have accomplished this growth
both internally and through selective acquisitions. Our revenues increased from
$37.2 million in 1995 to $201.0 million in 1999, representing a compound annual
growth rate of 52.6%. During the same period, we increased the number of our
common stock listings from 125 to 271.

Revenues

      Our revenues consist primarily of net gains earned from principal
transactions in securities for which we act as specialist, and commissions
revenue earned from specialist activities. Net gain on principal transactions
represents trading gains net of trading losses and transaction fees, and are
earned by us when we act as principal buying and selling our specialist stocks.
These revenues are primarily affected by changes in share volume and
fluctuations in price in our specialist stocks. Share volume for our specialist
stocks has historically been driven by general trends in NYSE trading volume, as
well as factors particularly affecting our listed companies, including increased
merger and acquisition activity, stock splits, greater frequency of company news
releases (i.e., earnings guidance and reports), heightened research analyst
coverage and investor sentiment. Commissions revenue consists of commissions we
earn when acting as agent to match buyers and sellers for limit orders executed
by us on behalf of brokers after a specified period of time; we do not earn
commissions when we match market orders. Commissions revenue is primarily
affected by share volume of the trades executed by us as agent. Other revenue
consists of proprietary trading revenue, an investment in a hedge fund and
short-term interest income. In 1999, net gain on principal transactions


                                       21
<PAGE>

represented 75.1% of our total revenues, commissions revenue represented 18.5%
of our total revenues, and other revenue represented 6.4% of our total revenues.

Expenses

      Our largest operating expense is compensation and benefits. Employee
compensation and benefits primarily consist of salaries and wages and
profitability-based compensation. Profitability-based compensation includes
compensation and benefits paid to managing directors, trading professionals and
other employees based on our profitability and the employee's overall
performance.

      Prior to our reorganization from partnership to corporate form, a large
portion of the compensation payments to our managing directors had not been
presented as part of operating expenses. The aggregate amount of these
compensation payments generally approximated LaB Investing Co. L.L.C.'s interest
in the income of LaBranche & Co., before managing directors' compensation.
Generally, these payments of compensation were allocated among our managing
directors based on their respective percentage interests in the profits of LaB
Investing Co. L.L.C. Subsequent to the reorganization transactions, we include
payments to managing directors in employee compensation and benefits expense.
Therefore, historical income before managing directors' compensation, limited
partnership interest in earnings of subsidiary and provision for income taxes
understates our operating costs.

Reorganization Transactions

      On August 24, 1999, we reorganized from partnership to corporate form.
Prior to the reorganization, we operated as LaBranche & Co., a limited
partnership and LaB Investing Co. L.L.C., a limited liability company and the
general partner of LaBranche & Co. As part of the reorganization, we redeemed
limited partnership interests in LaBranche & Co. and redeemed or purchased all
membership interests in LaB Investing Co. L.L.C. in exchange for a combination
of cash, indebtedness and common stock of LaBranche & Co Inc. The redemption of
the limited partnership interests was accounted for as a step acquisition under
the purchase method of accounting. The excess of purchase price over the limited
partners' capital accounts of $127.4 million was allocated to intangible assets.
Following the reorganization, LaBranche & Co Inc. is a holding corporation whose
assets consist primarily of our ownership interests in LaBranche & Co. and LaB
Investing Co. L.L.C.

      Simultaneously with the reorganization, we completed an initial public
offering of 10,500,000 shares of our common stock at a price of $14.00 per
share. In addition, we incurred indebtedness of approximately $100.0 million
through our Senior Note offering and $16.0 million through the issuance of other
senior indebtedness. In addition, LaBranche & Co. incurred $350,000 of
subordinated indebtedness. As a result of this increased indebtedness, our
interest expense following the reorganization transactions has been higher than
historical levels.

Income Taxes

      As a partnership, we were generally not subject to U.S. federal, state and
local income taxes, apart from the 4% New York City unincorporated business tax.
As part of our restructuring to a corporation, we are subject to U.S. federal,
state and local income taxes.

Completed Acquisitions

      In the third quarter of 1998, we acquired substantially all the assets of
Fowler, Rosenau & Geary, LLC (or "Fowler, Rosenau"). The acquisition was
accounted for under the purchase method and the excess of cost over estimated
fair value of the net assets acquired, totaling $25.8 million, was allocated to
goodwill. The results of the specialist operations formerly conducted by Fowler,
Rosenau have been included in our consolidated financial statements since July
1, 1998.

      In August 1997, we admitted Ernst & Company (or "Ernst") as a limited
partner in connection with our acquisition of the joint specialist operations of
Ernst, Homans & Co. (or "Homans") and Ware & Keelips, Inc. (or "Ware &
Keelips"). In connection with these transactions, we also hired as specialists
and admitted as members of LaB Investing Co. L.L.C. several individuals who had
previously worked as specialists for Ernst, Homans and Ware & Keelips. These
transactions were accounted for under the purchase method and the excess of cost
over estimated fair value of the net assets acquired, totaling $17.2 million,
was allocated to goodwill. The results of these specialist operations have been
included in our consolidated financial statements since August 1, 1997.

      In July 1997, Thomas Shanley, James Stack and Mark Soltz, formerly
specialists on behalf of Stern Bros., LLC (or "Stern"), were admitted as members
of LaB Investing Co. L.L.C. In connection with their admission, Messrs. Shanley,
Stack and Soltz contributed capital to LaB Investing Co. L.L.C. which was, in
turn, contributed to LaBranche & Co. This transaction was accounted for under
the purchase method and the excess of cost over estimated fair value of the net
assets acquired, totaling $7.8 million, was allocated to goodwill. The results
of these specialist operations have been included in our consolidated financial
statements since July 1, 1997.

Acquisitions Subsequent to Year End

      In March 2000, we completed the acquisition of Henderson Brothers in which
we acquired all their outstanding capital stock for approximately $230 million
in cash. In addition, we acquired Webco, through a merger where we were the sole
survivor. Under the terms of the agreement, we acquired Webco for 2.8 million
shares of our common stock, $10.9 million in cash and senior promissory notes in
the aggregate principal amount of $3.0 million, each bearing an interest rate of
10.0% per annum. These acquisitions were accounted for under the purchase method
and the excess of cost over estimated fair value of the net assets acquired,
currently estimated to be $199.4 million for Henderson Brothers and $27.6
million for Webco, will be allocated to intangible assets. The results of
specialist operations of each of the acquired companies will be included in our
consolidated financial statements beginning on the date of completion of the
applicable acquisition.

      Following the discussion of our historical results of operations, we have
provided a discussion of the results of operations for 1999 compared to 1998 on
a pro forma basis giving effect to certain transactions.

Year Ended December 31, 1999 Compared to Year Ended December 31, 1998

Revenues


                                       23
<PAGE>

      Total revenues increased 59.0% to $201.0 million for 1999, from $126.4
million for 1998, principally due to the increase in revenue from net gain on
principal transactions. Net gain on principal transactions increased 58.9% to
$151.0 million for 1999, from $95.0 million for 1998. This increase was
primarily due to an increase in share volume for our specialist stocks traded on
the NYSE. This increase, in turn, was primarily due to the Fowler, Rosenau
acquisition on July 1, 1998 under which we became the specialist for 76
additional common stock listings, and to increased share volume as principal in
our existing specialist stocks traded on the NYSE. Our share volume as principal
increased 62.7% to 9.6 billion shares for 1999, from 5.9 billion shares for
1998.

      Commissions revenue increased 39.8% to $37.2 million for 1999 from $26.6
million for 1998. This increase was due to an increase in share volume in which
we acted as agent. This increase, in turn, was primarily due to the increase in
the number of our common stock listings as a result of the Fowler, Rosenau
acquisition on July 1, 1998 and to increased share volume in our existing
specialist stocks traded on the NYSE. The share volume executed by us as agent
in our specialist stocks increased 41.4% to 4.1 billion shares for 1999, from
2.9 billion shares for 1998.

      Other revenue increased 166.7% to $12.8 million for 1999, from $4.8
million for 1998. This increase was primarily due to net gains in proprietary
trading of non-specialist securities and realized gains from a limited
partnership investment in a hedge fund.

Expenses

      Total expenses before managing directors' compensation and limited
partners' interest in earnings of subsidiary and provision for income taxes
increased 91.4% to $66.6 million for 1999, from $34.8 million for 1998.

      Employee compensation and related benefits increased 146.8% to $34.3
million for 1999, from $13.9 million for 1998. This increase was due to the
Fowler, Rosenau acquisition on July 1, 1998, which resulted in our employment of
36 additional individuals, and to the inclusion of managing director salary,
incentive-based bonus and related benefits in employee compensation from the
date of our reorganization in August 1999. As a percentage of total revenues,
employee compensation increased to 17.0% of total revenues for 1999, from 11.0%
of total revenues for 1998.

      Lease of exchange memberships expense increased 27.3% to $8.4 million for
1999, from $6.6 million for 1998. This increase was due to the increase in the
number of leased memberships from 44 to 48, primarily as a result of the hiring
of additional specialists and to an increase in the average annual leasing cost
of the memberships from approximately $180,000 to $192,000 per membership. As a
percentage of total revenues, lease of exchange memberships expense decreased to
4.2% for 1999, from 5.2% for 1998.

      Interest expense increased 130.6% to $8.3 million for 1999, from $3.6
million for 1998. This increase was primarily due to the issuance of $116.4
million of indebtedness which began accruing interest from August 24, 1999.

      Amortization of intangibles increased 84.0% to $4.6 million for 1999, from
$2.5 million for 1998. Amortization of intangibles increased as a result of the
Fowler, Rosenau acquisition, as well as the $127.4 million of intangible assets
recorded as a result of our acquisition of all of the limited partnership
interests in


                                       24
<PAGE>

LaBranche & Co. in connection with our reorganization transactions.

      Exchange, clearing and brokerage fees consist primarily of fees paid by us
as a specialist to the NYSE and to clearing houses. Fees paid by us to the NYSE
include primarily fees based on the volume of transactions executed as principal
and as agent, as well as a flat annual fee. Exchange, clearing and brokerage
fees expense increased 27.6% to $3.7 million for 1999, from $2.9 million for
1998. This increase was primarily attributable to an increase in share volume.

      Legal and professional fees increased 74.7% to $1.6 million for 1999, from
$916,000 for 1998. This increase was primarily the result of increased legal and
accounting fees due to our reorganization transactions.

      Occupancy expense increased 27.3% to $1.4 million for 1999, from $1.1
million for 1998. This increase was primarily the result of the leasing of
additional office space.

      Communications expense increased 20.0% to $1.2 million for 1999, from $1.0
million for 1998. This increase was primarily the result of additional
telephone, data retrieval and informational services utilized due to the growth
of our business.

      Other expenses increased 30.4% to $3.0 million for 1999, from $2.3 million
for 1998. The increase was primarily due to an increase in advertising and
promotional expenses.

      Income before managing directors' compensation and limited partners'
interest in earnings of subsidiary and provision for income taxes increased
46.8% to $134.5 million for 1999, from $91.6 million for 1998.

      Managing directors' compensation decreased 4.4% to $56.2 million for 1999,
from $58.8 million for 1998 as a result of the inclusion of managing director
salary, incentive-based bonus and related benefits in employee compensation from
the date of our reorganization transactions.

      Limited partners' interest in earnings of subsidiary decreased 3.8% to
$25.3 million for 1999, from $26.3 million for 1998 as a result of our
reorganization, at which time we acquired all of the limited partnership
interests in LaBranche & Co.

      Provision for income taxes increased 512.8% to $23.9 million for 1999,
from $3.9 million for 1998 as a result of an increase in our profitability and
the federal, state and local income taxes to which we are subject as a result of
our reorganization from partnership to corporate form.

Summary Pro Forma Consolidated Financial Data

      The following information compares our operating results for the years
ended December 31, 1999 and 1998 on both a historical basis and a pro forma
basis, assuming our acquisition of Fowler, Rosenau had occurred on January 1,
1998, instead of July 1, 1998, and assuming our reorganization from partnership
to corporate form and the related transactions had occurred as of January 1,
1998. This pro forma information does not give effect to our acquisitions of
Henderson Brothers and Webco in March 2000. The following pro forma consolidated
financial information has been prepared by our management

had the above described transactions occurred on the dates indicated or that may
be achieved in the future.

Notes to Statement of Operations Data

(A)   Includes the pro forma pre-acquisition results of Fowler, Rosenau for the
      six months ended June 30, 1998.

(B)   Employee compensation and benefits was adjusted to reflect managing
      directors' compensation based on the revised compensation policies, which
      were implemented at the time of the reorganization. Under this policy, a
      compensation pool of up to 30% of pre-tax income is set aside for managing
      directors. The pro forma compensation adjustment reflects managing
      directors' compensation, which is comprised of an annual base salary of
      approximately $8.5 million (34 managing directors at $250,000), and the
      remaining balance as bonus. The pro forma adjustment also includes
      compensation expenses related to employee restricted stock awards of $14.8
      million which vest over five years and result in an annual expense of
      approximately $3.0 million. The pro forma adjustment does not include any
      other compensation expenses related to employees who are not managing
      directors.

(C)   Reflects pro forma repayment of $5.0 million of subordinated liabilities
      owed to a limited partner and reverses the related interest expense.
      Reflects the issuance of Senior Notes of $100.0 million, the issuance of a
      $16.0 million note and $350,000 of subordinated indebtedness and the
      related interest expense.

(D)   Reflects amortization of intangibles related to redemption of limited
      partners' interests and the Fowler, Rosenau acquisition for a full year of
      1998.

(E)   Managing directors' compensation was adjusted to reverse the actual
      amounts previously recorded.

(F)   Reflects reversal of limited partners' interest in earnings of subsidiary.

(G)   Reflects federal, state and local income taxes at estimated corporate tax
      rates.

(H)   EBITDA means net income (loss) before interest expense, taxes,
      depreciation and amortization. EBITDA is not a generally accepted
      accounting principles measure and may not be comparable to similarly
      titled items of other companies. You should not consider EBITDA as an
      alternative to net income (loss) or any other generally accepted
      accounting principles measure of performance as an indicator of our
      operating performance or as a measure of liquidity. EBITDA does not
      represent funds available for management's discretionary use because
      certain future cash expenditures are not reflected in the EBITDA
      presentation. Some investors use these data as an indicator of a company's
      ability to service debt.

Results of Operations on a Pro Forma Basis

Revenues

      Total revenues increased 45.8% to $201.0 million for 1999, from $137.9
million for 1998, principally due to the increase in revenue from net gain on
principal transactions. Net gain on principal


                                       27
<PAGE>

transactions increased 53.0% to $151.0 million for 1999, from $98.7 million for
1998. This increase was primarily due to an increase in share volume for our
specialist stocks traded on the NYSE. Our share volume as principal increased
62.7% to 9.6 billion shares for 1999, from 5.9 billion shares for 1998.

      Commission revenue increased 9.4% to $37.2 million for 1999, from $34.0
million for 1998. This increase was due to an increase in share volume in which
we acted as agent and to increased share volume in our Specialist stocks traded
on the NYSE. The share volume executed by us as agent in our Specialist stocks
increased 41.4% to 4.1 billion shares for 1999, from 2.9 billion shares for
1998.

      Other revenue increased 146.2% to $12.8 million for 1999, from $5.2
million for 1998. This increase was primarily due to net gains in proprietary
trading of non-specialist securities and realized gains from a limited
partnership investment in a hedge fund.

Expenses

      Employee compensation and related benefits increased 47.3% to $59.5
million for 1999, from $40.4 million for 1998. This increase was due to our
increased profitability which, in turn, led to an increase in our managing
director incentive-based bonus pool as described in Note A above. As a
percentage of total revenues, employee compensation increased to 29.6% of total
revenues for 1999, from 29.3% of total revenues for 1998.

      Interest expense increased 4.1% to $15.1 million for 1999, from $14.5
million for 1998. This increase was the result of additional interest on
increased subordinated debt borrowings. For both 1999 and 1998, pro forma
interest expense reflects the issuance of Senior Notes of $100.0 million, the
issuance of a $16.0 million note and $350,000 of subordinated indebtedness and
the related interest expense as described in Note B above.

      Provision for income taxes increased 67.4% to $46.2 million for 1999, from
$27.6 million for 1998 as a result of an increase in our profitability.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

      A majority of our specialist related revenues are derived from trading by
us as principal. These activities involve primarily the purchase, sale or short
sale of securities for our own account. These activities are subject to a number
of risks, including risks of price fluctuations and rapid changes in the
liquidity of markets. In any period, we may incur trading losses in 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
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 NYSE specialist operations, which
represented 3.3% of our total revenues in 1999. We may incur trading losses as a
result of these trading activities.

      We have developed a risk management process which is intended to balance
our ability to profit from our specialist activities with our exposure to
potential losses. In addition, we have trading limits


                                       28
<PAGE>

relating to our proprietary trading desk.

      Although we have adopted risk management policies, we cannot be sure that
these policies have been formulated properly to identify or 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.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders of
LaBranche & Co Inc. and Subsidiaries:

      We have audited the accompanying consolidated statements of financial
condition of LaBranche & Co Inc. and Subsidiaries (collectively, the "Company")
as of December 31, 1999 and 1998, and the related consolidated statements of
operations, changes in stockholders' equity/members' capital and cash flows for
each of the three years in the period ended December 31, 1999. These financial
statements and the condensed financial statements referred to below are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

      We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

      In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of LaBranche & Co Inc. and
Subsidiaries as of December 31, 1999 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999 in conformity with accounting principles generally accepted in
the United States.

      Our audits were conducted for the purpose of forming an opinion on the
basic financial statements taken as a whole. The parent company only condensed
financial statements appearing on pages F-20 through F-24 are presented for the
purpose of complying with the Securities and Exchange Commission's rules and are
not part of the basic financial statements. Such statements have been subjected
to the auditing procedures applied in the audit of the basic financial
statements and, in our opinion, are fairly stated in all material respects in
relation to the basic financial statements taken as a whole.

                      LaBRANCHE & CO INC. and SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND DESCRIPTION OF BUSINESS

      The consolidated financial statements include the accounts of LaBranche &
Co Inc., a Delaware corporation (the "Holding Company"), and its subsidiaries,
LaB Investing Co. L.L.C., a New York limited liability company ("LaB
Investing"), and LaBranche & Co., a New York limited partnership (collectively,
the "Company"). LaB Investing is the sole general partner of LaBranche & Co. and
has a partnership interest in LaBranche & Co. of 84.1%. The Holding Company is
the sole limited partner of LaBranche & Co. and owns the remaining partnership
interest of 15.9%. The Holding Company is also the sole member of LaB Investing,
thereby providing the Holding Company with 100.0% ownership in LaBranche & Co.
LaBranche & Co. operates primarily as a specialist in certain equity securities
listed on the New York Stock Exchange, Inc. ("NYSE").

2. INITIAL PUBLIC OFFERING AND DEBT ISSUANCE

      On August 24, 1999, the Company reorganized from partnership to corporate
form, upon the members of LaB Investing exchanging their membership interests
for common stock in the Holding Company, and completed its initial public
offering. In that offering, the Company sold 10,500,000 shares of common stock
and received net proceeds of $134.8 million. Concurrently with the offering, the
Company issued $100.0 million aggregate principal amount of senior notes. See
Note 12 for further information regarding the long term debt.

3. SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

      The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at
the date of the consolidated financial statements and the reported amounts of
revenues and expenses during the reporting period. Management does not believe
that actual results will differ materially from these estimates.

Intangible Assets

      Intangible assets are comprised of the Company's specialist stock list,
trade name, and goodwill from acquisitions and the limited partner buyout that
occurred in concurrence with our reorganization to corporate form. The
specialist stock list and trade name are being amortized on a straight-line
basis over 40 years and the goodwill is being amortized on a straight-line basis
over 15 years. The allocation of purchase price and determination of useful
lives were based upon an independent appraisal. The useful life of the
specialist stock list was determined based upon analysis of historical turnover
characteristics of the specialist stocks.

      The Company continually evaluates whether later events and circumstances
have occurred that


                                       F-9
<PAGE>

indicate the remaining estimated useful life may warrant revision or that the
remaining balance may not be recoverable. When factors indicate that intangible
assets should be evaluated for possible impairment, the Company uses an estimate
of undiscounted net income over the remaining life in measuring whether the
assets are recoverable.

Exchange Memberships

      Exchange memberships owned by the Company are carried at cost.

      Certain members of the Company have contributed the use of 9 memberships
on the NYSE to the Company. These memberships are subordinated to claims of
general creditors and are carried at market value with a corresponding amount
recorded in subordinated liabilities. Lease payments are paid by the Company to
its members for the use of the exchange memberships at a rate that is
commensurate with the rent paid to nonaffiliated parties for the use of their
exchange memberships.

Cash and Cash Equivalents

      Cash and cash equivalents consist of cash and highly liquid investments
with maturities of less than three months.

Securities Transactions

      Securities transactions and the related revenues and expenses are recorded
on a trade date basis. Securities owned and securities sold, but not yet
purchased are reflected at market value and unrealized gains and losses are
reflected in net gain on principal transactions. Dividends and Securities and
Exchange Commission ("SEC") fees are also included in net gain on principal
transactions. Dividend income and expense are recognized on the payable date,
which does not differ materially from the ex-date.

Depreciation and Amortization

      Depreciation and amortization are calculated using the straight-line
method over the estimated useful lives of office equipment and leasehold
improvements.

Collateralized Financing Transactions

      Securities purchased and sold under agreements to resell and repurchase,
as well as securities borrowed and loaned for which cash is deposited or
received, are treated as collateralized financing transactions and are recorded
at contract amount.

Collateral

      The Company continues to report assets as owned when they are pledged as
collateral in secured financing arrangements and the secured party cannot sell
or repledge the assets or the Company can substitute collateral or otherwise
redeem it on short notice. The Company continues not to report securities
received as collateral in secured financing arrangements because the debtor
typically has the right to substitute or redeem the collateral on short notice.


                                      F-10

Reportable Operating Segment

      The Company considers its present operations to be one reportable segment
for purposes of presenting consolidated financial information and for evaluating
its performance. The financial statement information presented in the
accompanying consolidated financial statements is consistent with the
preparation of financial information for the purpose of internal use.

Managing Directors' Compensation

      Prior to the reorganization on August 24, 1999 the managing directors of
LaBranche & Co. were the members of LaB Investing. LaBranche & Co. paid out
substantially all of its earnings as compensation expense to its managing
directors. Subsequent to August 24, 1999, the managing directors of the Company
are compensated based on an annual salary as well as an incentive based
compensation pool which is determined based upon a certain percentage of pre-tax
income.

New Accounting Pronouncement

      The Financial Accounting Standard Board has issued Statement of Financial
Accounting Standards No. 133 ("SFAS No. 133"), "Accounting for Derivative
Instruments and Hedging Activities," which is effective for periods beginning
after June 15, 2000. Management does not believe the impact of the adoption of
SFAS No. 133 on the Company's financial position or results of operations, will
be material.

5. INCOME TAXES

      Prior to its conversion to corporate form, LaBranche & Co. operated as a
partnership and generally was not subject to U.S. federal and state income
taxes. The earnings of LaBranche & Co., however, were subject to local
unincorporated business taxes. The members were taxed on their proportionate
share of the partnership's taxable income or loss. Effective with its conversion
from partnership to corporate form on August 24, 1999, the Company became
subject to U.S. federal, state and local corporate income taxes. The Company
accounts for taxes in accordance with Statement of Financial Accounting
Standards ("SFAS") No. 109, "Accounting for Income Taxes", which requires the
recognition of tax benefits or expenses on temporary differences between the
financial reporting and tax bases of its assets and liabilities. Deferred tax
assets and liabilities relate to stock-based compensation and amortization of
certain intangibles. As a result of its conversion to corporate form, the
Company recognized the tax effect of the change in its income tax rate on the
earnings attributable to the period from August 24, 1999 to December 31, 1999.
The Company's effective tax rate differs from the federal statutory rate
primarily due to its conversion to corporate form and non-deductible
amortization of intangibles. The components of provision for income taxes
reflected on the consolidated statements of operations are set forth below:

6. CAPITAL AND NET LIQUID ASSET REQUIREMENTS

      LaBranche & Co., as a specialist and member of the NYSE, is subject to SEC
Rule 15c3-1 as adopted and administered by the NYSE and the SEC. LaBranche & Co.
is required to maintain minimum net capital, as defined, equivalent to the
greater of $100,000 or 1/15 of aggregate indebtedness, as defined.

      As of December 31, 1999 and 1998, LaBranche & Co.'s net capital, as
defined under SEC Rule 15c3-1, was $161.4 million and $86.5 million,
respectively, and exceeded minimum requirements by $159.9 million and $85.2
million, respectively. LaBranche & Co.'s aggregate indebtedness to net capital
ratio was .13 to 1 and .24 to 1, respectively.

      The NYSE also requires members registered as regular specialists to
establish that they can meet, with their own net liquid assets, a minimum dollar
amount which shall be the greater of $1.0 million or 25% of their position
requirement ("Rule 104.2"). In 1998, due to the concentration of LaBranche &
Co.'s specialist book, the NYSE required LaBranche & Co. to maintain minimum net
liquid assets of the greater of 120% of LaBranche & Co.'s Rule 104.2 position
requirement, or $90.0 million, adjusted by the amount of the position
requirement for any new stock allocations. The position requirement is the
ability to assume positions in stocks in which they are registered of 30,000
shares of each S&P 500 common stock, 22,500


                                      F-12
<PAGE>

shares in all other common stocks, 4,500 shares in each convertible preferred
stock and 1,800 shares in each nonconvertible preferred stock. The term "net
liquid assets" for a specialist who also engages in transactions other than
specialist activities is based on its excess net capital determined in
accordance with SEC Rule 15c3-1.

      As of December 31, 1999 and 1998, LaBranche & Co.'s NYSE minimum required
dollar amount of net liquid assets, as defined, was $93.6 million and $90.6
million, respectively, compared to actual net liquid assets, as defined, of
$175.9 million and $103.1 million, respectively.

7. ACQUISITIONS

      Effective July 1, 1997, LaBranche & Co. acquired a portion of the
specialist operations of Stern Bros., LLC for an aggregate purchase price of
approximately $9.3 million, representing an 8.3% total general partners'
interest in LaBranche & Co. The goodwill associated with the acquisition was
approximately $7.8 million.

      Effective August 1, 1997, LaBranche & Co. acquired the specialist
operations of Ernst, Homans, Ware & Keelips for an aggregate purchase price of
approximately $18.5 million, representing general and limited partnership
interests totaling 16.4%. The excess purchase price over fair value of net
assets acquired was approximately $17.2 million.

      Effective July 1, 1998, LaBranche & Co. acquired the specialist operations
of Fowler, Rosenau & Geary, L.L.C. ("Fowler") for an aggregate purchase price of
approximately $45.0 million, representing a 22.4% total general and limited
partners' interest in LaBranche & Co. The excess purchase price over fair value
of net assets acquired was approximately $25.8 million.

      Effective August 24, 1999, the limited partnership interests of $37.1
million in LaBranche & Co. were acquired at an excess purchase price of $127.4
million over the limited partners' capital balances. The redemption of the
limited partners' interests is accounted for as a step acquisition under the
purchase method of accounting. The excess of purchase price over the limited
partners' capital balances was allocated to intangible assets and assigned lives
as follows:

                                        Original Amount    Life
                                        ---------------    ----

8. COMMITMENTS

      During 1998, LaBranche & Co. secured a $75.0 million committed line of
credit with a U.S. commercial bank. The agreement matured on June 25, 1999. In
June 1999, the Company amended and extended the committed line of credit to
$100.0 million through June 23, 2000.

                Thereafter......................   3,372,000

      These leases contain escalation clauses providing for increased rentals
based upon maintenance and tax increases.

9. SUBORDINATED LIABILITIES

      LaBranche & Co. is a party to subordinated loan agreements under which it
has indebtedness approved by the NYSE for inclusion as net capital, as defined.
Interest is payable quarterly at various annual rates. Eleven of the agreements
representing $6,823,000 mature within the last six months of 2000 and seven
agreements representing $3,385,000 mature within the first six months of 2001.
These agreements all have automatic rollover provisions, and each scheduled
maturity date will be extended an additional year, unless the lender gives
LaBranche & Co. seven months' advance notice that the maturity date will not be
extended. Interest expense incurred for the years ended December 31, 1999, 1998
and 1997 on these agreements was approximately $1.1 million, $1.3 million and
$1.2 million, respectively. Two of the holders representing $850,000 of
subordinated loan agreements maturing in November 2000 have notified LaBranche &
Co. that the scheduled maturity date will not be extended.

      LaBranche & Co. also issued seven notes representing aggregate
indebtedness of $20,000,000 which mature on September 15, 2002 and bear interest
at an annual rate of 8.17% payable on a quarterly basis. LaBranche & Co. also
issued five notes representing aggregate indebtedness of $15,000,000 which
mature on June 3, 2008 and bear interest at an annual rate of 7.69% payable on a
quarterly basis. These notes are senior to all other subordinated notes of
LaBranche & Co. Interest expense incurred for the years ended December 31, 1999,
1998 and 1997 on these notes was approximately $2.8 million, $2.3 million and
$340,000, respectively. The agreements covering these subordinated notes require
the Company to comply with certain covenants that, among other things, restrict
the type of business in which the Company may engage, sets certain net capital
levels and prohibits restricted payments.

      LaBranche & Co. also issued a subordinated note for $1,300,000 due March
2, 2001 with an annual rate of 10.0%, payable on a quarterly basis. Interest
expense incurred for the year ended December 31, 1999 on the note was
approximately $123,333. This agreement has an automatic rollover provision, and
the scheduled maturity date will be extended an additional year, unless the
lender gives LaBranche & Co. seven months' advance notice that the maturity date
will not be extended.

      Exchange memberships contributed pursuant to subordination agreements in
the amount of $20,700,000 comprise the remaining subordinated liabilities.

10. EARNINGS PER SHARE

      Earnings per share ("EPS") are computed in accordance with SFAS No. 128,
"Earnings Per Share". Basic EPS is calculated by dividing net income by the
weighted-average number of common shares outstanding. For purposes of
determining weighted average shares outstanding for periods prior to the
Company's reorganization from partnership to corporate form, the outstanding
shares were determined based on the conversion ratio of members' capital to
common stock issued to the members upon reorganization.

      The computations of basic and diluted EPS are set forth below (000's
omitted, except per share data):

representing 1,062,600 shares of common stock and options to purchase an
aggregate of 1,200,000 shares of common stock were not included in the
calculation of diluted earnings per share due to their antidilutive effect.

11. EMPLOYEE INCENTIVE PLANS

Equity Incentive Plan

      The Company has elected to account for stock-based employee compensation
plans in accordance with Accounting Principles Board Opinion ("APB") No. 25 as
permitted by SFAS No. 123, "Accounting for Stock-Based Compensation". In
accordance with APB No. 25, compensation expense is not recognized for stock
options that have no intrinsic value on the date of grant.

      The Company sponsors an Equity Incentive Plan which provides for grants of
incentive stock options, nonqualified stock options, restricted shares of common
stock, restricted stock units, unrestricted shares and stock appreciation
rights.

      A maximum of 4,687,500 shares of common stock has been reserved for
issuance under the Equity Incentive Plan. The maximum number of shares of common
stock with respect to which options, restricted stock, restricted stock units or
other equity-based awards may be granted under the Equity Incentive Plan during
any calendar year to any employee may not exceed 500,000 shares, subject to
adjustment upon certain corporate transactions.


                                      F-15

      On August 18, 1999, restricted stock units with respect to 1,059,000
shares of common stock were granted to employees who were not managing directors
with an issue cost of $0 to the employees and a fair market value of $14 per
share. In October 1999, restricted stock units for an additional 3,600 shares of
common stock were issued to an employee with an issue cost of $0. The restricted
stock units, which are subject to continuing service with the Company and other
restrictions, will generally vest in three annual installments commencing on the
third anniversary of the grant date. Compensation expense is being recognized
over the five-year vesting period on a straight-line basis. For the year ended
December 31, 1999, the Company recorded compensation expense and a credit to
additional paid-in capital of approximately $1.1 million related to these
restricted stock units.

Stock Options

      On August 18, 1999, options to purchase an aggregate of 1,200,000 shares
of common stock were granted to executive officers of the Company at market
value. Of these options, options to purchase 1,000,000 shares, which are subject
to continuing service with the Company and other restrictions, will become
exercisable in three equal annual installments commencing on the first
anniversary of the date of grant. The options to purchase the remaining 200,000
shares vested on January 7, 2000 and 100,000 shares become exercisable on July
7, 2000 and 100,000 shares on July 7, 2001. As of December 31, 1999, there were
no options exercisable. These options will generally expire ten years from the
date of grant, unless sooner terminated or exercised. Pursuant to APB No. 25, no
compensation expense was recognized since, on the date of grant, these options
had no intrinsic value. As of December 31, 1999, the outstanding options had an
exercise price of $14 and a remaining life of approximately 10 years.

      The estimated fair value of options granted was $4.97 per option. Fair
value is estimated as of the grant date based on a binomial option pricing model
using the following assumptions:

                   Risk-free interest rate....         5.25%
                   Expected life..............         7 yrs
                   Expected volatility........           40%
                   Dividend yield.............            0%

      In accordance with SFAS No. 123, compensation expense was not recognized
on the date of the grant of the options since these options had no intrinsic
value. If the Company were to recognize compensation expense under the
fair-value based method of SFAS No. 123, the net income would have decreased by
approximately $843,000 resulting in pro forma net income and earnings per share
as follows:

                                                     Year Ended
                                                  December 31, 1999
                                              (000s omitted, except per
                                                     share data)

       Net income, as reported................                   $29,034
       Pro forma net income...................                    28,191

The effect of applying SFAS No. 123 in the pro forma disclosure above may not be
representative of the potential pro forma effect on net income in future
periods.

Annual Incentive Plan

      The Company also sponsors an Annual Incentive Plan. Managing directors and
other employees designated by management will be eligible to participate. Under
this plan, a compensation pool of up to 30% of the Company's pre-tax income, or
such lesser percentage determined by the compensation committee, will be set
aside for managing directors and other employees selected by the compensation
committee to participate in this plan. In determining the compensation pool, the
compensation expense relating to the grant of restricted stock units at the time
of the reorganization of the Company to corporate form is deducted. Under the
plan, no individual participant may receive more than 25% of the compensation
pool for any fiscal year.

12. LONG TERM DEBT

      Effective August 24, 1999, the Holding Company issued $100.0 million
aggregate principal amount of senior notes. The notes bear interest at a rate of
9.5% annually and mature on August 15, 2004. The carrying value of the senior
notes as of December 31, 1999 is $99.8 million. The discount on the bond is
being amortized as an adjustment to interest expense over the life of the senior
notes. Debt issuance costs incurred as a result of the senior note offering are
approximately $2.5 million, which are being amortized as on a straight line
basis over the life of the senior notes. Interest expense incurred for the year
ended December 31, 1999 was approximately $3.3 million. The indenture covering
the senior notes includes certain covenants that, among other things, limits the
Company's ability to: borrow money; pay dividends or repurchase stock; make
investments; engage in transactions with stockholders and affiliates; create
liens on assets; and sell assets or engage in mergers and consolidations except
in accordance with certain specified conditions, as defined.

      In addition, in connection with the reorganization of the Company from
partnership to corporate form on August 24, 1999 the Holding Company issued a
note in an aggregate principal amount of $16.0 million as partial payment for
the acquisition of a limited partner interest. Of the $16.0 million total, $6.0
million is payable on the first anniversary of issuance, $5.0 million is payable
on the second anniversary of issuance and $5.0 million is payable on the third
anniversary of issuance. The note bears interest at the annual rate of 9.5%.
Interest expense incurred for the year ended December 31, 1999 was approximately
$538,000.

13. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

      Statement of Financial Accounting Standards No. 107, "Disclosures About
Fair Value of Financial Instruments," requires companies to report the fair
value of financial instruments for certain assets and liabilities. Substantially
all of the Company's financial instruments are short-term in nature or carry
market interest rates and, accordingly, approximate fair value.


                                      F-17
<PAGE>

      The fair value of the fixed rate debt at December 31, 1999, in millions,
is as follows:

                                     Carrying Value       Fair Value
                                     --------------       ----------

             Senior Debt...........            $99.8           $97.0
             Fixed Rate Note.......            $16.0           $15.9

The fair value of the senior notes was determined based upon its market value as
of December 31, 1999. The fair value of the fixed rate note was determined using
current market rates to discount its cash flows.

14. FINANCIAL INSTRUMENTS WITH CONCENTRATION OF CREDIT AND OFF-BALANCE SHEET
    RISK

      As a specialist on the NYSE, LaBranche & Co. is engaged in various
securities trading and lending activities. In connection with its activities as
a specialist, LaBranche & Co. assumes positions in stocks for which it is
responsible. LaBranche & Co. is exposed to credit risk associated with the
nonperformance of counterparties in fulfilling their contractual obligations
pursuant to these securities transactions. LaBranche & Co. is exposed to market
risk associated with the sale of securities not yet purchased, which can be
directly impacted by volatile trading on the NYSE. Additionally, in the event of
nonperformance and unfavorable market price movements, LaBranche & Co. may be
required to purchase or sell financial instruments, which may result in a loss
to LaBranche & Co.

      LaBranche & Co. enters into collateralized financing agreements in which
it extends short-term credit to major financial institutions. LaBranche & Co.
controls access to the collateral pledged by the counterparties, which generally
consists of U.S. equity and government securities. The value and adequacy of the
collateral are continually monitored. Consequently, the risk of credit loss from
counterparties' failure to perform in connection with collateralized lending
activities is minimal.
