Compensation and related benefits for certain employees and certain company-wide professional fees are
allocated to our two principal business segments. However, certain revenues and administrative and corporate overhead expenses, which consist primarily of interest on our public debt, are not specifically allocated to our two principal business
segments and thus are treated as other revenues and expenses. A description of our principal business segments is presented below.

Our
Specialist and Market-Making Segment

The Specialist and Market-Making Industry

Generally, trading of securities on the NYSE, the AMEX and other listed securities markets is conducted through a process 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 securities. The number of specialist units on the NYSE and the AMEX has decreased
substantially over the past several years due to consolidation within the industry. There are currently seven NYSE specialist firms, of which the five largest, as ranked by number of specialist stocks, were responsible for 94.7% and 95.2% of the
average daily share volume traded on the NYSE in 2006 and 2005, respectively. There are currently nine equity specialist firms, 11 option specialist firms and 10 ETF specialist firms on the AMEX. Many other firms act as market-makers in these
securities on the AMEX, adding liquidity to the market in addition to the exclusive specialists obligation to do so. There are also many other market-makers on the other exchanges on which we make markets.

On the NYSE, specialist firms for cash equity securities compete for the original listing of these securities 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 security, based on criteria specified by the listing company. The issuer then
meets with each specialist firm presented by the allocation committee. Within one week after meeting the competing specialist firms, the listing company selects a specialist firm. Currently, almost every company listing on the NYSE chooses its
specialist firm under the second allocation method. Our competitors in the NYSE cash equities specialist business currently are Spear, Leeds & Kellogg Specialists LLC (a division of Goldman Sachs Group), Bear Wagner Specialists LLC, Bank of
America Specialists, Van der Moolen Specialists USA, LLC, SIG Specialists, Inc. and Kellogg Specialist Group.

On the AMEX, the specialist
firm for each equity security, option and future competes for the original listing of that security through an allocation process organized by the AMEX. The AMEX has an allocation committee, which selects the specialist firm for each security based
on specified criteria, giving weight to the desires of the listed company. On both the NYSE and AMEX, the specialist for each ETF is chosen by either the exchange or the ETF issuer.

When assigned a particular security, the specialist firm agrees to specific obligations. The specialist is required to maintain, as far as practicable, a
fair and orderly market. This implies that the trading will have reasonable depth and price continuity, so that, under normal circumstances,



4



---

a customer may buy or sell the security 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 specialist process, either electronically or through manual orders. In performing its obligations, the specialist firm is exposed to many transactions that occur in each of
its specialist securities, either through electronic orders or floor brokers. In any given transaction, the specialist firm may:



| |  |  | electronically or manually set opening prices for its specialist securities and may, in certain circumstances, match the highest bids with the lowest offers,
permitting buyers and sellers to trade directly;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



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



| |  |  | act as an agent, in certain circumstances, 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
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | use its own capital to buy or sell securities for its own account.
| | - |  | ------------------------------------------------------------------

In addition to normal specialist functions, a specialist in ETFs may provide seed money to the ETF, creating shares in such ETF by purchasing and depositing a group of securities and/or cash into the fund.

The specialist firm's decision to buy or sell its specialist securities as principal may be based on obligation or inclination. For
example, the specialist firm may be obligated to buy or sell its specialist securities 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 securities as principal based on market conditions. In actively-traded securities, the specialist firm continually buys and sells its specialist securities 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 securities. In fulfilling its specialist obligations, however, the specialist firm may, at times, be obligated to trade against
the market, or may be prevented from participating in a trade, which could adversely impact its profitability. In addition, the specialist firm's trading practices are subject to a number of restrictions, as described in Rules Governing Our
Specialist and Market-Making Activities.

Recent Trends in Trading

Specialist and market-making firms generate revenues by providing liquidity with their own capital in their specialist and market-making securities.
Specialist firms' revenues generally are significantly impacted by the share volume of trading and volatility on the applicable market. Market activity historically has tended to be cyclical, and trading volumes from 2002 through 2004 evidenced a
decline in individual and institutional trading.

Since 2000, ETFs have grown as an alternative to other investments. ETFs are share-based
investment funds that pool investors capital and trade on stock exchanges throughout the



5



---

day at prices determined by the market. ETFs attempt to imitate a stock market index or narrowly defined basket, rather than actively add or remove stocks.
As a result, these ETFs offer investors the diversification advantages of a mutual fund, while also possessing certain tax and other advantages of traditional stocks. According to data provided by the Investment Company Institute, ETF assets grew to
approximately $422.0 billion as of December 31, 2006 from $296.0 billion as of December 31, 2005, representing an annual growth rate of approximately 42%. Some of the more recognizable ETFs are the Nasdaq 100 Tracking Stock (QQQQ),
Standard & Poors Depositary Receipts (SPDRs) and Vanguard Index Participation Receipts (VIPERS). We believe the increase in program trading during this period is at least partially related to the growth in ETFs because hedging
trades executed by market makers tend to be done electronically and in small increments.

In 2006, trading volumes in cash equity
securities also continued to grow. Average daily trading volume on the NYSE increased in 2006 to 1.8 billion shares from approximately 1.6 billion shares in 2005. Although the increases in trading volume in 2005, in part, helped to stabilize our
cash equity specialist revenues in 2005, there were several periods of trading in 2006 in which there were significant unilateral market moves upward or downward, causing us to generate poor trading results due to our affirmative obligations as
specialist. From 2002 through 2004, there was a period of declining trading volume, which may have been attributable to:



| |  |  | a relatively slow return by the retail investor to the equity markets following the 2000-2002 bear market;
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | popular interest in alternative investments, particularly residential real estate and commodities; and
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | the continued emergence of a new class of investors, including hedge funds, that invests in non-traditional instruments.
| | - |  | ------------------------------------------------------------------------------------------------------------------------

We believe several other factors negatively impacted equity specialists revenues from 2002 through 2004, and again in 2006, including:



| |  |  | declining volatility of stock prices as measured by the CBOEs Volatility Index®, a key measure of market expectation of near-term volatility and investor sentiment. As volatility in markets
diminishes, the need for specialists to employ capital to mitigate volatility decreases, which in turn reduces specialists level of principal participation; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | increased program trading as a percentage of total NYSE average daily share volume. Program trading and the decimalization of stock prices often results in a number
of smaller orders executed through the NYSEs system. As a result, block-trading strategies have become less prevalent.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Although our revenues from our cash equities specialist business stabilized in 2005, these factors affected our cash
equities business again in 2006.

The recent changes in investor behavior from concentration on individual stocks to alternatives such as
sector and index trading, as well as ETFs, also has substantially fueled the growth for trading in options, futures and ETFs. Accordingly, over the past few years we have increased our focus on our options, futures and ETFs specialist and market
making-operations. Although our trading results in our sector, index, options and ETF business has continued to grow, our performance in those products lagged in 2006 as compared to the substantial growth in the prior three years.

The majority of trades in NYSE-listed stocks continues to take place on the NYSE. In 2006, specialist firms handled approximately 72% of trades in
NYSE-listed stocks, a decline from approximately 79% in 2005. The percentage of trades in NYSE-listed stocks on the floor of the NYSE is affected as follows:



| |  |  | some stocks are listed on multiple exchanges, such as regional exchanges, and trades take place on those exchanges as well as in the over-the-counter market and
through alternative trading systems (ATSs); and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | at times, significant volume in NYSE-listed stocks takes place before and after regular NYSE trading hours, off of the NYSE.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------

Technological advances have contributed to increased trading through ATSs, such as electronic communications networks, or ECNs, and electronic crossing
systems. While the first ECN was created in 1969, most of the ECNs currently in operation were started only since the 1990s. 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, professional 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. It is possible that the presence of these ATSs and other emerging electronic trading systems have contributed to the overall
decline in the percentage of equity shares traded on the NYSE over the past five years from approximately 82% to approximately 72%. Notwithstanding the presence of these ATSs and other emerging trading technologies, the NYSE remains the predominant
trading marketplace for listed securities. It is unclear, however, how ATSs and other new technologies, in addition to other recent events (such as the merger of the NYSE and Archipelago Holdings, Inc. (Archipelago) in March 2006 (the
NYSE/Archipelago merger), the HYBRID model and Regulation NMS, all as described in Rules Governing Our Specialist and Market-Making Activities below), will continue to affect the future percentages of trading in listed
stocks on the NYSE.

In response to the development of ATSs, in 2001 the NYSE launched Network NYSE, a suite of market
information and auto-execution products offering new choices to different types of customers. Some examples of these products include:



| |  |  | NYSE Direct+®, an automatic execution service for limit orders up to 1,099 shares, enabling investors to automatically execute orders at the national best bid offer;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | NYSE Open Book(SM), an online market data product allowing subscribers to view information on the NYSE limit order books; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | Institutional Express(SM), an electronic gateway to satisfy large order requirements and the growing information needs of NYSE member firms and their institutional
customers.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The NYSEs HYBRID market, launched in December 2006, substantially changed these products. The HYBRID is discussed in
detail in Rules Governing Our Specialist and Market-Making Activities below.

Our Specialist and Market-Making Operations

Due largely to acquisitions and an increase in the number of our specialist stocks from 1997 through 2001, we experienced strong
revenue growth in our Specialist and Market-Making segment during that period. From 2002 through 2004, however, our aggregate specialist and market making revenues declined from $395.8 million in 2002 to $235.2 million in 2004.

Our revenues stabilized in 2005, and our aggregate specialist and market-making revenues increased to an aggregate of $246.1 million. These results were
due, in part, to an overall increase in market trading and our strategic response to the above-described changes in investor behavior from concentration on individual stocks to alternatives such as sector and index trading, as well as ETFs.

Our Specialist and Market-Making segment revenues in 2006 increased to $427.7 million. This increase is mainly due to the realized and
unrealized net gain on the NYSE/Archipelago merger of $220.3 million offset by decreases in net gains on principal transactions and commissions. We did not recognize any gain on the NYX transaction in 2005. The net gains from principal transactions
were impacted mainly in the second and third quarter of 2006 due to our affirmative obligations to trade as specialist and adverse market conditions relative to our positions. Commission income continued to erode from an average of $3.5 million per
month in 2005 to an average of $3.0 million per month in 2006. In December 2006, the NYSE Market announced that the commission income earned by specialists would be partially replaced by a three-tier trading rebate.

Over the past few years, we have increased our focus on our options, futures and ETFs specialist and market making-operations. The Specialist and
Market-Making segment has been employing more capital in its trading activities on more exchanges, and in derivative products and ETFs, in order to seek growth opportunities while maintaining a leadership position in the cash equities specialist
market. Our initial acquisition strategy and strategic organic growth has enabled us to gather products in our specialist and market-making operations on additional



8



---

exchanges and in additional countries. A restructuring of certain of our specialist and market-making subsidiaries has allowed us to develop our specialist
and market-making operations across various exchanges and marketplaces. These initiatives have also enabled us to better allocate and deploy our capital, workforce and technology across our operations in order to more efficiently seek out
opportunities as they arise.

Our NYSE and AMEX Equity Specialists

Our NYSE and AMEX equity specialist operations are conducted through our LaBranche & Co. LLC subsidiary. As a specialist in equity securities and
rights listed on the NYSE and in equity securities on the AMEX, LaBranche & Co. LLCs role is to maintain, as far as practicable, a fair and orderly market in its specialist stocks. In doing so, it provides a service to its listed
companies, and to the brokers, traders and investors who trade in its specialist stocks. As a result of our commitment to providing high quality specialist services, we have developed a solid reputation among our constituencies, including investors,
members of the Wall Street community and our listed companies.

Since our initial public offering, we have increased the number of our
listed companies and specialist market share both internally and through acquisitions. Since the NYSE implemented its new specialist allocation process in March 1997, we have been selected by 216 new listed companies, resulting from 572 listing
interviews through December 31, 2006. In addition, we have acquired eleven specialist operations since 1997, adding approximately 500 NYSE common stocks and 52 AMEX common stocks. As a result of internal growth and selective acquisitions, our
LaBranche & Co. LLC subsidiary currently is a leading NYSE specialist as illustrated by the following data:



| |  |  | the dollar volume traded of stocks for which LaBranche & Co. LLC was the specialist on the NYSE in 2006 was $3.8 trillion, or 24.9% of total 2006 NYSE
specialist dollar volume, and was $3.4 trillion in 2005, or 25.1% of total 2005 NYSE specialist dollar volume;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the share volume traded of stocks for which LaBranche & Co. LLC was the specialist on the NYSE in 2006 was 105.9 billion, or 26.4% of total 2006 NYSE
share volume, and was 101.4 billion in 2005, or 26.4% of total 2005 NYSE share volume; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | as of December 31, 2006, the total number of LaBranche & Co. LLCs NYSE common stock listings was 555, or 20.1% of all NYSE common stock
listings, and as of December 31, 2005, its total number of NYSE common stock listings was 566, or 21.3% of all NYSE common stock listings.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

By these three measurements, LaBranche & Co. LLC was one of the largest NYSE specialist firms as of December 31, 2006 and 2005. In addition, LaBranche & Co. LLC acted as the specialist for 221
other NYSE-listed securities (e.g., preferred stocks and derivative securities).

As of December 31, 2006, LaBranche & Co.
LLCs listed companies included:



| |  |  | 109 of the S&P 500 Index companies;
| | - |  | -----------------------------------

Our Options,
Futures and ETFs Specialists and Market-Makers

Through September 25, 2002, our AMEX specialist operations for both equities and
options were conducted entirely by LaBranche & Co. LLC. Since then, in order to continue our expansion into new products and markets, we have conducted our options, ETFs and other derivatives specialist and market-making business activities
on the AMEX, NYBOT, PHLX, Chicago Board Options Exchange® (CBOE), and other exchanges through our LSP subsidiary, and have conducted our NYSE ETFs specialist operations through our LSPS subsidiary. Our equity specialist activities on the AMEX continue to be
conducted by LaBranche & Co. LLC.

In August and September 2005, we reorganized our options, futures and ETFs specialist and
market-making operations under our LSHI holding company subsidiary in order to facilitate the liquidity and working capital management of our specialist and market-making activities. During 2006, our options, futures and ETFs specialist and
market-making operations continued to expand through our LSP and LSPS subsidiaries. From 2002 through 2006, we expanded our market-making activities to different derivative products as well as to other exchanges, which contributed significantly to
our growing balance sheet over this period. As of December 31, 2006, we acted as the specialist for 719 options, 3 futures and 75 ETFs listed on the AMEX, NYBOT, PHLX and other exchanges, and acted as a market-maker in ETFs, options and futures
on several exchanges. We also were the specialist in 34 ETFs listed on the NYSE.

We are responsible for maintaining a fair and orderly
market in the trading of our specialist options, futures and ETFs. In doing so, we may at times be obligated to trade against the market, adversely impacting the profitability of the trade or creating a position that may not necessarily be desired.
To hedge the risk of our derivative positions, we may buy or sell the underlying asset(s). As a market-maker, we also trade these derivative securities as principal out of both obligation and inclination. Our principal competitors in the ETF
specialist business are Spear, Leeds & Kellogg Specialists LLC and Bear Wagner Specialists LLC. Our options and futures specialist business is not dominated by any one or group of competitors.

As a registered market-maker in options, ETFs and futures, our Specialist and Market-Making segment generally engages in a course of dealings that is
reasonably calculated to contribute to the maintenance of a fair and orderly market. We also may hedge these positions with the underlying assets or other financial instruments. In our market-making function, we bring immediacy and liquidity to the
markets when we choose to participate.

In January 2005, we formed LSPE to be a market-maker for ETFs traded on the London Stock Exchange,
Euroex and Euronext exchanges. In August 2005, we formed LSPH to be a market-maker in ETFs traded in Hong Kong and to conduct hedging transactions in Hong Kong markets related to our specialist and market-making activities. As part of our LSP-entity



10

reorganization in August and September 2005, both LSPE and LSPH became wholly-owned subsidiaries of LSHI. LSPE became a registered broker-dealer with the
UKs Financial Securities Authority (FSA) in March 2006, and LSPH registered as a broker-dealer with Hong Kongs Securities and Futures Commission in October 2006 (SFC). Upon complete implementation of trading
operations, we expect LSPE and LSPH to strengthen our specialist and market-making relationships with U.S. ETF issuers abroad, which we believe will help our Specialist and Market-Making segment further diversify its exchange base and better manage
its risk.

Our Specialist Support Services

In April 2002, BV was organized to represent LaBranche & Co. LLC in European markets and to provide client services to LaBranche & Co. LLCs European-listed companies. BV was established under
Dutch law, and its office is in Amsterdam, The Netherlands. Through a services agreement, BV provides monitoring and trading services for LaBranche & Co. LLCs specialist stock positions, as specifically directed by appropriately
designated LaBranche & Co. LLC personnel. In addition, BV markets the services of our specialist entities to existing and prospective European NYSE-listed issuers.

For detailed financial information in connection with our Specialist and Market-Making segment, please see Managements Discussion and
Analysis of Financial Condition and Results of OperationsSpecialist and Market-Making Segment Operating Results and Note 17 to the Financial Statements filed herewith.

Rules Governing Our Specialist and Market-Making Activities

Under NYSE and AMEX rules, a
specialist has a duty to maintain, as far as practicable, a fair and orderly market in its specialist securities. In order to fulfill its obligations, the specialist must at times trade for its firms own account, even when it may adversely
affect the firms profitability. 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 its specialist stocks. The specialist is not expected to act as a barrier in a rising market or as 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.

Although the NYSE and other markets are now highly
automated, and quotations are nearly always automated, regulatory rules continue to require a specialist to make 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.

In addition, the
specialist cannot be in a control relationship with any of its listed companies. Generally, this means a specialist may not acquire more than 5% of any common or



11



---

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 with, receive payments or loans from, or engage in certain business transactions with any of its listed companies. It is our general policy that employees of our Specialist and Market-Making businesses may not personally trade in or own
any securities for which we are the specialist, with limited exceptions.

New Market Rules. The market structure in which we operate
is changing and we believe we are in a position to adapt to new market rules and structures. The most notable events that are having a direct impact on our core business are the NYSE's merger with Archipelago in March 2006, the NYSEs pending
merger with Euronext, the recent changes in the NYSEs market structure to the HYBRID model and the SEC's structural changes in the U.S. equity trading markets.

The HYBRID market model allows most NYSE orders to be automatically executed through Direct+® where the specialist systematically provides liquidity to meet its specialist obligation while, also permitting the specialist to implement the
traditional auction market structure when necessary. The purported goal of the HYBRID market is to provide the speed of electronic executions without limiting order size, yet preserving the central market with the presence and participation of
specialists, who can provide price discovery, liquidity and capital to the market in order to dampen volatility.

To create this HYBRID
model, in December 2006 and January 2007, the NYSE altered its Direct+® system by eliminating the former limits on size, timing and types of orders that could be executed automatically. As a result, almost all of the NYSEs trading volume is now executed automatically through the
Direct+® system, thus eliminating the need for the
specialist to manually execute orders in most cases. The specialist, instead, maintains a fair and orderly market by interacting with orders electronically through algorithms, adding liquidity to the Direct+® marketplace to meet its obligations. The increased automation allows us to be more
focused on adding liquidity to the marketplace rather than manually executing orders that can be electronically matched. This has resulted in reduced staffing requirements. Our technical and trading staff are implementing and refining our trading
technology to participate in the highly automated NYSE market, while our specialists stand ready on the floor of the NYSE to perform their traditional functions when necessary in a fast market to inject stability, liquidity and capital into the
market.

Specifically, the NYSE's HYBRID system eliminates the 1,099-share restriction on NYSE Direct+® orders, as well as the prohibition against entering orders for the same account within
30 seconds, and permits market orders and immediate-or-cancel orders to be eligible for Direct+® execution. In addition, the NYSE's HYBRID system contains a number of other new features designed to create a liquidity pool accessible for electronic and auction price discovery; the
opportunity for benefits associated with human judgment at the point of sale; and accountable performance with focused communication by specialists. We believe that we have successfully made the first steps to operate within the more electronic,
automated marketplace that exists today.

On April 6, 2005, the SEC adopted Regulation National Market System (Regulation
NMS). Regulation NMS is expected to become effective March 2007 for automated trading



12



---

centers and could have a significant impact on the regulation of trading on securities exchanges and marketplaces. Specifically, the rule establishes
inter-market protection against trade-throughs for all NMS stocks and protection of only those quotations that are immediately accessible through automatic execution. The rule generally does not contain the "opt-out" exception originally
proposed by the SEC, which would have (1) allowed customers (and broker dealers trading for their own accounts) to "opt-out" of the protections of the rule by providing informed consent to the execution of their orders, on an order-by-order
basis, in one market without regard to the possibility of obtaining a better price in another market, and (2) taken into account the differences between the speed of execution in electronic versus manual markets by providing an automated market
with the ability to trade through a non-automated market at a price up to a certain amount away from the best bid or offer displayed by the non-automated market. The rule also is anticipated to protect the best bids and offers of each exchange,
NASDAQ, and the NASD's Alternative Display Facility. The NYSEs HYBRID market was designed to be in full compliance with Regulation NMS and, because we are fully operational under the HYBRID market, we believe we are in compliance with the
provisions of Regulation NMS and will continue to adapt to the NYSE and other markets in order to do so. We currently do not anticipate that Regulation NMS will have a material effect on our business, other than with respect to the effects of the
new HYBRID market and other more electronic exchanges, as more fully described herein and in Item 1A, Risk Factors below.

There may be regulatory changes following the closing of the merger of the NYSE and Euronext, which was approved by the SEC on February 15, 2007. Please see The NYSE/Archipelago Merger, Proposed NYSE Regulation/NASD Merger and
Pending NYSE/Euronext Merger for a more detailed discussion of those transactions and their potential market-rule effect.

The
NYSE/Archipelago Merger, Proposed NYSE Regulation/NASD Merger, and Pending NYSE/Euronext Merger.On March 7, 2006, Archipelago and the NYSE consummated a merger in which they combined their businesses and each became a wholly-owned
subsidiary of NYSE Group, Inc., a newly-created, for-profit and publicly-traded holding company. Consequently, the former NYSE business is now comprised of three separate entities under the NYSE Group: New York Stock Exchange LLC; NYSE Market,
Inc. (NYSE Market); and NYSE Regulation, Inc. (NYSE Regulation). New York Stock Exchange LLC will hold the equity interests of NYSE Market and NYSE Regulation.

It is anticipated that NYSE Regulation will merge with the NASD by the second or third quarter of 2007 (subject to SEC approval), forming one
self-regulatory agency going forward. In announcing the merger of these self-regulatory organizations, representatives from each agency stated that following the consummation of the merger, there will be one set of regulatory rules to apply to all
broker-dealers, regardless of the exchange in which they operate. Currently, we are subject to the separate regulatory rules of both the NASD and the NYSE in our various entities.

In order to allow us to operate our NYSE specialist activities on the floor of the NYSE, the NYSE Market has issued trading licenses to all registered
broker-dealers wishing to conduct business on the floor of the NYSE, subject to payment of a fee to NYSE Market, which for 2007 is $50,000 annually per license. These trading licenses replaced the trading rights provided by the ownership or lease of
an NYSE membership prior to the NYSE/Archipelago merger. In January 2006, we participated in a Dutch auction for these trading licenses and successfully bid for 90 trading licenses in our Specialist and Market-Making segment (five
additional licenses were obtained for our Execution and Clearing segment operations). For the 2007 fiscal year, we



13



---

hold an aggregate of 48 trading licenses between our Specialist and Market-Making and Execution and Clearing segments. The number of trading licenses
required to conduct business on the floor of the NYSE has declined because we now require fewer specialists on the floor to operate in the newer more automated environment. Organizations holding trading licenses generally are subject to the same
rules that were applicable to member organizations prior to the NYSE/Archipelago merger. Each trading license entitles its holder to physical and electronic access to the trading facilities of NYSE Market, subject to such limitations and
requirements as may be specified, and in each case includes the right to designate a natural person, subject to pre-approval by NYSE Regulation (or the NASD following the proposed merger, if consummated), who may have physical access to the floor
and facilities of NYSE Market to trade.

In connection with the NYSE/Archipelago merger, the NYSE amended NYSE Rule 103B, the Exchange
Allocation Policy. The NYSE Market is granted the right to determine the number and identity of specialist firms from which a new listing issuer may choose its specialist, provided the group consists of at least four specialist firms. The NYSE
Market and the issuer are provided with the same kind of material with respect to each specialist firm applicant as was formerly reviewed by the NYSEs Allocation Committee prior to the NYSE/Archipelago merger. As a result, the NYSE/Archipelago
merger did not materially affect the specialist allocation process.

In an agreement dated June 1, 2006, as amended and restated as of
November 24, 2006, NYSE Group and Euronext N.V. agreed to combine their businesses under a newly formed holding company, NYSE Euronext, Inc. (NYSE Euronext). Pursuant to the terms of the agreement, Euronexts business will be
brought under NYSE Euronext through an exchange offer and a post-closing reorganization, and NYSE Groups business will be brought under NYSE Euronext through a merger. The SEC approved the NYSE/Euronext merger on February 15, 2007.

Pursuant to the exchange offer, which commenced February 15, 2007, NYSE Euronext will pay to the Euronext shareholders an aggregate
of 21.32 in cash, without interest, and 0.98 of a share of NYSE Euronext common stock for each share of Euronext stock they own. In lieu of receiving this standard consideration, Euronext shareholders have the right to elect to receive for
each of their tendered Euronext shares (a) 1.2633 shares of NYSE Euronext common stock or (b) 95.07 in cash, without interest, subject to proration in the event either option is oversubscribed. This exchange offer is expected to
close on March 21, 2007. Immediately after the completion of the Euronext exchange offer, the NYSE/Euronext merger will proceed with NYSE Group stockholders having the right to receive one share of NYSE Euronext common stock for each share of
NYSE Group common stock. The new NYSE Euronext shares we own will be subject to the same transfer restrictions, if any, that the shares of NYSE Group common stock were subject prior to the merger. The NYSE/Euronext merger is intended to be tax-free
to the NYSE Group shareholders, including us.

After completion of the NYSE/Euronext merger, the NYSE Group shareholders and Euronext
shareholders are expected to own 59% and 41%, respectively, of the NYSE Euronext shares. There will be approximately 267 million shares of NYSE Euronext common stock outstanding and we expect to own 3,126,093 shares of NYSE Euronext common
stock, or approximately 1.15% of the total outstanding shares.

Based on current information, we do not expect the NYSE/Euronext merger to have a material effect on the
regulatory structure of the NYSE that existed prior to the merger, other than any anticipated changes following the proposed merger of NYSE Regulation and the NASD. Please see  Regulatory Matters and Rules Governing Our
Specialist and Market-Making Activities for a more detailed description of our regulatory environment.

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. Our corporate relations effort is devoted to serving our listed companies by providing them with current market information and insight on general market trends. We organize an annual educational conference that reviews trends in the
securities industry and equity markets. For newly listed companies, we provide additional investor relations support services to assist the companies with their transition to the exchange on which they are listed. These services add significant
value for companies considering a listing on an exchange.

Competition in the Specialist and Market-Making Industry

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



| |  |  | the strength of our capital base;
| | - |  | ---------------------------------



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



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

The specialist industry experienced a vast and accelerated consolidation over the period of 1995 through 2001. The five largest specialist units, as
ranked by their number of specialist stock listings, accounted for 94.7% of the daily share volume traded on the NYSE in 2006 as compared to 95.2% in 2005. The competition for obtaining newly listed companies is intense. We expect competition to
continue and intensify as some of our competitors may have greater financial resources and product service offerings.

As more fully
described above in The NYSE/Archipelago Merger, Proposed NYSE Regulation/NASD Merger and Pending NYSE/Euronext Merger, under the newly released NYSE Rule 103B, The Exchange Allocation Policy, the NYSE Market is granted
the right to determine the number and identity of specialist firms from which a new listing issuer may choose a specialist, provided the group consists of at least four specialist firms. The NYSE Market and the issuer are provided with the same kind
of material with respect to each specialist firm applicant as was formerly reviewed by the NYSEs Allocation Committee prior to the NYSE/Archipelago merger. As a result, the NYSE/Archipelago merger did not materially affect the specialist
allocation process.

Our Specialist and Market-Making Segments Competitive Position

We are committed to providing the highest quality service to our various constituencies. Our strong competitive position is based on the following
factors:



| |  |  | Leading Position in the Specialist and Market-Making Market. We have a long-standing reputation as a leading specialist firm. We have successfully grown our
business and improved our services through widely varying market conditions. Our cash equities specialist operations during 2006 accounted for 24.9% of the dollar value and 25.1% of the specialist share volume traded on the NYSE, and 127 of our
specialist common stock listings were securities of non-U.S. companies as of December 31, 2006. By these measures, we were the largest specialist firm on the NYSE. We are also one of the largest ETF specialist firms on the NYSE and AMEX, as the
specialist in 109 ETFs out of an aggregate of 236 listed ETFs as of December 31, 2006. We are also one of the largest market-makers on various exchanges in options, futures and ETFs.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Diverse and High Quality Specialist and Market-Making Securities. The companies for whose securities we are specialist and market-maker operate in a variety
of industries, including financial services, media, oil and gas, retail, technology and telecommunications. Many of these companies are leaders in their respective fields. They range in market capitalization from some of the smallest on the NYSE and
AMEX to some of the largest and most well-known. Being the specialist and market-maker in the securities of industry leaders could benefit us as these leading companies expand their businesses through internal growth and acquisitions.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Ability to deploy capital efficiently. We have employed more capital in our trading activities on more exchanges, and in derivative products and ETFs, in
seeking growth opportunities while maintaining a leadership position in the cash equities specialist market. Our initial acquisition strategy and strategic organic growth has enabled us to gather products in our specialist and market-making
operations on additional exchanges and in additional countries. A restructuring of certain of our specialist and market-making subsidiaries has allowed us to develop those operations across various exchanges and market places. The organizational
structure of our Specialist and Market-Making segment should enable us to better allocate and deploy our capital, workforce and technology across our operations in order to more efficiently seek out opportunities as they arise.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Strong Trading and Technology Skills. We utilize our trading skills to actively participate as principal in trading our specialist and market-making
securities. We significantly improve liquidity in our specialist and market-making securities and quickly and ably create ETFs for our ETF specialist customers, particularly during periods of market volatility. Additionally, as the securities
trading marketplace has become more electronic, as further evidenced by the NYSEs HYBRID market model,
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



16



---

| | we have developed electronic trading capabilities which allow us to interact in the fast and more automated HYBRID markets. Due to our investment
in automated quoting technology, we moved all our listings to the HYBRID system in mid-December 2006. Our technology group is also developing more advanced algorithmic models that may be used in electronic trading markets and in the HYBRID model.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Innovative Customer-Oriented Services. In addition to our specialist and market-making functions on the trading floor, we provide our specialist-based listed
companies with a high level of service (e.g., detailed information on the trading activity of their securities), as well as customized support services to assist in their investor relations efforts.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Completed Acquisitions and Strategic Organic Growth. Since 1997, we have acquired eleven specialist operations, adding approximately 500 NYSE common stocks
and 52 AMEX common stocks, solidifying our position as one of the leading NYSE specialist firms, as well as establishing and expanding our presence on the AMEX. We also have continued our organic growth by creating the current LSHI structure to
facilitate our expansion within the options, futures and ETFs specialist and market-making market. Our growth as a specialist in ETFs has played a particularly meaningful role in this growth, as we are now the specialist in 109 ETFs traded on the
NYSE and the AMEX.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our Execution and Clearing Segment

Recent Trends in Execution and Clearing Industry

The traditional clearing industry has, over
the last few years, consolidated down to a small number of highly capitalized and extremely focused competitors. Mostly owned by or affiliated with large investment or commercial banks, these few top competitors command the dominant share of the
fully-disclosed correspondent clearing market. As a result, barriers to entry have risen and the capital expenditures necessary to maintain market share have increased.

As the result of years of advances in order delivery and execution technology, trading costs for customers across all categories (retail, institutional, etc.) have dropped dramatically. These advances in trading
technologies, and the resulting economies afforded the customer, have also engendered an entirely new style of investment management, where algorithms embedded in servers generate, direct and account for orders with minimal human interaction.

In addition, there has arisen a number of non-traditional execution venues that bypass the traditional exchanges and ECNs in which
institutions can trade directly with each other without exposing orders to market-wide price verification.

Our Execution and Clearing Operations

LFS, which is the sole operating entity constituting our Execution and Clearing segment, provides clearance and execution services
to a range of clients. To our broker dealer correspondents, we provide traditional clearance services. To our own customers, which include institutions and individuals, we provide a range of customized execution services, including direct-access
brokerage.



17



---

LFS does not focus on commoditized bulk clearance and execution. LFS targets businesses where our
flexibility, customization and a versatile clearance platform provide us with a competitive advantage.

Our Institutional Execution Group
(IEG) provides institutions with highly customized service built around special execution needs. IEG focuses on timely executions with minimal market impact. IEG handles and clears trades on every major domestic stock exchange, with
straight-through processing from order origination to trade execution. IEG also provides soft dollar execution and other administrative services to institutional customers. IEG has active relationships with over 291 accounts and is developing its
business nationwide.

Our Execution and Clearing segment revenues in 2006 increased to $53.7 million. This increase is mainly due to the
realized and unrealized net gain on the NYX transaction of $18.3 million offset by decreases in commissions. We did not recognize any gain on the NYX transaction in 2005.

For detailed financial information relating to our Execution and Clearing segment, please see Managements Discussion and Analysis of Financial Condition and Results of OperationsExecution and
Clearing Segment Operating Results and Note 17 to the Financial Statements filed herewith.

Regulatory Matters

The securities industry in the United States is subject to regulation under both Federal and state laws. In addition, the SEC, NYSE, AMEX and other
regulatory organizations require compliance with their rules and regulations. On January 21, 2007, a majority of the member firms approved a consolidation of the NASDs and NYSEs regulatory arms. The consolidation will result in a
single regulatory division that will be responsible for member examination, enforcement, arbitration and mediation, as well as market regulation for the NYSE, NASDAQ, AMEX, ISE and Chicago Climate exchanges. This combined regulatory division is
expected to begin operation in the second quarter of 2007.

Our broker-dealer subsidiaries are subject to regulations concerning the
operational and financial aspects of their respective businesses. They are subject to registration requirements of various government entities and self-regulatory organizations (commonly referred to as SROs) with which they must comply before they
may conduct business. Our broker-dealer subsidiaries are also subject to laws, rules and regulations requiring them to comply with financial reporting rules, trade practices, capital structure obligations and record retention requirements. Failure,
or even the assertion by a regulatory organization of failure, by any of our broker-dealer subsidiaries 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 its directors, officers or employees and other negative consequences, which could have an adverse effect on our business. Refer to Legal ProceedingsSpecialist Trading Investigations. From time to time, in the
ordinary course of business, we have been subject to fines for violations of such laws, rules or regulations.



18



---

Our trading subsidiaries are under constant review by the NYSE, the AMEX and the other exchanges on which
they conduct operations on all aspects of their operations and financial condition. In particular, as part of the price discovery mechanism implemented by the NYSE, every NYSE specialist transaction is published immediately and broadcast worldwide.
The NYSEs Market Surveillance Division employs sophisticated monitoring and requires adherence to stringent rules approved by the SEC in its examination of NYSE specialists' trading in all stocks. The NASDs AMEX Regulation Division
monitors and reviews specialists adherence to AMEX rules and regulations, as well.

The USA PATRIOT Act of 2001 (the PATRIOT
Act), which was extended on March 9, 2006, contains anti-money laundering and financial transparency laws and mandates the implementation of various new regulations that apply to broker-dealers and other U.S. financial institutions,
including procedures for verifying client identity at account opening, and obligations to monitor client transactions and report suspicious activities. Through its provisions, the PATRIOT Act seeks to promote cooperation among U.S. financial
services companies, regulators and law enforcement officials in identifying parties that may be involved in terrorism or money laundering. The increased obligations of financial institutions, including our broker-dealer subsidiaries, require the
implementation and maintenance of internal control procedures which have increased our costs and may subject us to liability.

Capital
Requirements

Our broker-dealer subsidiaries are also subject to net capital requirements as required by SEC Rule 15c3-1, and net liquid
asset requirements as required by the NYSE and AMEX. Please refer to Managements Discussion and Analysis of Financial Condition and Results of OperationsLiquidity and Capital Resources for our broker-dealer subsidiaries
capital requirements and actual amounts.

Failure by any of our broker-dealer subsidiaries to maintain the required net capital and/or net
liquid assets may subject it to suspension or revocation of SEC registration or suspension or expulsion by the respective exchanges of which it is a member.

Employees

As of December 31, 2006, we had 429 full-time employees, of which 305 were employed at our Specialist and
Market-Making segment, 83 were employed at our Execution and Clearing segment, and 41 were employed at the holding company. As of February 13, 2007, we had 385 full-time employees, of which 267 were employed at our Specialist and Market-Making
segment, 82 were employed at our Execution and Clearing segment and 36 were employed at our holding company. In 2006, we developed and implemented a restructuring plan which resulted in the termination of 126 positions mainly due to increased
automation with the introduction of the HYBRID market. Of the 385 employees at February 13, 2007, the specialist and market-making segment employs 13 traders and support personnel in foreign offices in London, Hong Kong and Amsterdam.

|Item 1A. | RISK FACTORS
|-------- | ------------

The following risk factors should be
carefully considered in evaluating our business and us because they have a significant impact on our business, operating results, financial condition, and cash flows. If any of these risks actually occurs, our business, financial condition,
operating results and/or cash flows could be adversely affected.

The market structure in which we operate may change, making it
difficult for us to maintain our levels of profitability.

The market structure in which we operate is changing and these changes could
have an adverse affect on our financial condition and results of operations. These changes may make it difficult for us to maintain and predict levels of profitability. The most notable recent events that could have a direct impact on our core
business are the NYSE's merger with Archipelago in March 2006, the NYSEs pending merger with Euronext, recent changes in the NYSEs HYBRID market model and the SEC's structural changes in the U.S. equity trading markets.

To create the HYBRID model, in December 2006 and January 2007, the NYSE altered its Direct+® system by eliminating the former limits on size, timing and types of orders that could
be executed automatically. As a result, almost all of the NYSEs trading volume is now executed automatically through the Direct+® system, thus eliminating the need for the specialist to manually execute orders in most cases. The specialist, instead, maintains a fair and orderly
market by interacting with orders electronically through algorithms, adding liquidity to the Direct+® marketplace to meet its obligations. The increased automation allows us to be more focused on adding liquidity to the marketplace rather than manually executing orders that can be
electronically matched.

Specifically, the NYSE's HYBRID system eliminates the 1,099-share restriction on NYSE Direct+® orders, as well as the prohibition against entering
orders for the same account within 30 seconds, and permits market orders and immediate-or-cancel orders to be eligible for Direct+® execution. In addition, the NYSE's HYBRID system contains a number of other new features designed to create a liquidity pool accessible for electronic
and auction price discovery; the opportunity for benefits associated with human judgment at the point of sale; and accountable performance with focused communication by specialists. However, with speed being the most important factor under the
HYBRID system, the ability of the specialist to participate in trades could be limited in many instances. The lifting of order limitations has caused a significant decline in the number of large orders that used to be the mainstay of the auction
outcry market where major brokerage houses utilized on-floor brokers to obtain best executions of large block orders and where the specialist infusion of capital produced best execution prices on significant trades. In the HYBRID, the NYSEs
computers break up significant size orders into multiple executions for small incremental price changes and large brokerage houses internalize large orders by buying and selling securities between customer and proprietary accounts without these
orders ever reaching a public market. Although the daily statistics of the number of shares traded on the NYSE appear high, the NYSEs market share, in fact, has declined. Internalization and the HYBRID have also decreased the specialists
opportunity to participate in the capital markets in a way that could prevent the specialist firms from having any predictable yardstick of profitability.



20



---

The purported goal of the HYBRID market is to provide the speed of electronic executions without limiting
order size, yet preserving the auction market. In light of the fact that many more electronic orders will match naturally in the electronic Direct+® system, and considering we are in the early stages of implementing and refining our electronic trading systems, and our market participation rates are
lower, we have not yet been fully able to determine whether the HYBRID model will significantly hinder our ability to participate in transactions as principal. In the event we cannot develop electronic trading systems to interact with orders and
continue to act as principal in a substantial percentage of trades, our financial results could be adversely impacted.

On April 6,
2005, the SEC adopted Regulation NMS. Regulation NMS, which is expected to become effective March 2007, could have a significant impact on the regulation of trading on securities exchanges and marketplaces. The rule establishes inter-market
protection against trade-throughs for all NMS stocks and protection of only those quotations that are immediately accessible through automatic execution. The rule generally does not contain the "opt-out" exception originally proposed by
the SEC, which would have (1) allowed customers (and broker dealers trading for their own accounts) to "opt-out" of the protections of the rule by providing informed consent to the execution of their orders, on an order-by-order basis, in one
market without regard to the possibility of obtaining a better price in another market, and (2) taken into account the differences between the speed of execution in electronic versus manual markets by providing an automated market with the
ability to trade through a non-automated market at a price up to a certain amount away from the best bid or offer displayed by the non-automated market. The rule also is anticipated to protect the best bids and offers of each exchange, NASDAQ, and
the NASD's Alternative Display Facility.

While it is too early to anticipate the impact that Regulation NMS could have on our trading, it
is possible that the rule could materially affect our compliance costs and alter the competitive environment in which our Specialist and Market-Making segment functions. As discussed above, the restrictions of regulation and the impact of Regulation
NMS could continue to decrease order flow to the NYSE, which could impact our core business profitability. Further, as previously discussed, the internalization of orders, in which large brokerage firms are able to cross trades among their large
client bases without directing any business to the major exchanges and marketplaces, could restrict order flow and, consequently, our ability to participate in trades. The effects of this trend have already been felt in the significant decrease in
order flow being directed to the NYSE, and we have not yet been able to anticipate the effects it may have on our profitability going forward.

There also may be regulatory changes following the closing of the merger of the NYSE and Euronext, which was approved by the SEC on February 15, 2007. Any failure by us to adapt to these changes or the new HYBRID market and Regulation
NMS could materially adversely affect our results in the new NYSE Market following the merger. Please see Risks Associated with the Recently-Consummated NYSE/Archipelago Merger, Proposed NYSE Regulation/NASD Merger and Pending
NYSE/Euronext Merger for a more detailed discussion.

The growth of electronic trading and the introduction of new technology may adversely affect our
business and may increase competition.

Technology is fundamental to our business and our industry. The continued growth of electronic
trading and the introduction of new technologies, particularly the NYSEs new HYBRID system, is changing our businesses and presenting us with new challenges. Securities, futures and options transactions are increasingly occurring
electronically, both on our own systems and through other alternative trading systems, and it appears that the trend toward alternative trading systems will continue and probably accelerate. This acceleration could further increase program trading
and decrease our ability to participate in transactions as principal, which could cause a decrease in our profitability. Some of these alternative trading systems compete with our Specialist and Market-Making businesses, and we may experience
continued competitive pressures in these and other areas. In addition, the increased use by our clients of low-cost electronic trading systems and direct electronic access to trading markets could cause a reduction in commissions and thus the
earnings of our Execution and Clearing business. The NYSEs adoption of its HYBRID market for trading securities may increase pressure on our cash equities specialist business as customers execute more of their NYSE-related trades
electronically and off of the NYSE. To date, we have only implemented the basic specialist algorithms to trade on the HYBRID model. Using this basic platform, our participation rates have decreased in the HYBRID model, but we are continuing to
develop more advanced algorithms to better participate in the market. We have invested significant resources into the development of electronic trading systems and expect to continue to do so, but there is no assurance that the revenues generated by
these systems will yield an adequate return on our investment, particularly given the increased program trading, increased percentage of NYSE stocks trading off of the NYSE Market and the change in the commissions program on the NYSE.

Our technology is only as good as the systems with which it interacts. This means that there are times when system failures at both the NYSE and the AMEX
have had an impact on our profitability. The NYSE and AMEX support a small fund to reimburse market makers for losses caused by the systems. We cannot provide assurance that the NYSE and AMEX will be able to reimburse us for all losses incurred as a
result of NYSE or AMEX systems failure on a timely basis or at all, which could adversely affect our results of operations and financial condition.

An inability to timely or successfully develop enhanced proprietary specialist trading systems to interact on the NYSEs HYBRID model, as well as the increase in electronic trading on other exchanges, may adversely affect our
business and profitability.

As the securities trading marketplace has become more automated, specifically with the imminent
effectiveness of Regulation NMS and the new HYBRID model on the NYSE, we have developed electronic trading capabilities which allow us to interact in the fast and more automated HYBRID markets. In addition, other markets, such as the
AMEX and several options exchanges, have introduced their own version of the HYBRID market in order to comply with Regulation NMS. All of these hybrid, or electronic-based, markets have required us to expend significant programming efforts and
resources to transact business in the electronic marketplace. Throughout this process, we have developed trading systems to interact on these markets and these systems, but it is too early in the new electronic trading environment to fully determine
the success of these trading technologies and their effect on our profitability.



22



---

Our HYBRID and related trading algorithms have been developed with a view toward complying with our
specialist and market-making obligations to ensure we perform our roles correctly and in compliance with rules and regulations. There can be no assurance that our internally-developed specialist and market-making algorithms do not have errors or can
prevent rule violations. In the event all violations cannot be prevented, these trading programs may expose us to regulatory fines and penalties by NYSE Regulation, or the combined NYSE Regulation and NASD regulatory body in the future.

In addition, our technology group is also developing more advanced proprietary algorithmic models that would enable us to provide additional liquidity
throughout each trading day based on both obligation and opportunity. These models have not yet been fully implemented, although their use in our specialist business is probable. We cannot provide assurance that our more advanced trading systems
will be profitable. We also cannot provide assurance that these proprietary trading systems will enable us to compete effectively with our direct competitors. Our profitability and ability to compete may depend on the ability of our business and
technology personnel to effectively adapt these advanced trading systems to changes in the marketplace, while adequately maintaining our specialist and market-making obligations. In the event we cannot successfully build and adapt this trading
technology, our financial condition and results of operations may be adversely affected.

Our future success will depend on the ability
to upgrade information and communications systems, and any failure to do so could harm our business and profitability.

The development
of complex communications and new technologies, including Internet-based technologies, may render our existing information and communications systems outdated. In addition, our information and communications systems must be compatible with those of
the NYSE and the AMEX. As a result, when and if the NYSE or the AMEX upgrades its systems, we will need to make corresponding upgrades. Our future success will depend on our ability, on a cost-effective basis, to timely respond to changing
technologies. Our failure to do so could have an adverse effect on our business, financial condition and/or operating results.

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

We are subject to extensive regulation under federal and state laws that could result in investigations, fines or other penalties.

Our broker-dealer subsidiaries are subject to increasing regulatory inquiries and informal investigations
in the ordinary course of business and, as a result, are spending more resources on responding to, and defending, these inquiries and investigations. It is possible that these additional resources could result in increased legal and professional
fees, as well as additional fines and formal regulatory actions going forward. It is difficult to predict whether and to what extent any of these regulatory inquiries could escalate. However, if any of these ordinary inquiries progress into material
regulatory or legal proceedings, such proceedings could result in settlements, determinations or judgments requiring substantial payments of sanctions, fines and penalties, as well as the costs of defending these actions, which could materially and
adversely affect our business and operations.

On December 22, 2006, LaBranche & Co. LLC entered into an agreement with the
NYSE to settle investigations by the NYSE concerning our specialists alleged inability to comply with applicable securities laws and regulations relating to specialists order-handling obligations and NYSE rules concerning
firm-quote obligations, commitments from other markets, limit order display rules and short sales. Pursuant to the agreement, and without admitting or denying any wrongdoing, we paid on February 27, 2007 a total of $600,000 to
settle this matter. In addition, in December 2004, our LaBranche & Co. LLC subsidiary received a notice from the NASD Amex Regulation Division stating a preliminary determination by the NASD Amex Regulation Division's staff to seek
disciplinary action against LaBranche & Co. LLC for violations of certain federal securities laws and the AMEXs Constitution and Rules, including Sections 10(b), 9A and 17(a) of the Securities Exchange Act of 1934, in connection with
manual book freezes effected in one of LaBranche & Co. LLC's Amex specialist stocks during the period March 8, 2004 through October 21, 2004. This notice of possible disciplinary action has not yet been resolved. In addition, we
have been the subject of other investigations that have resulted in our paying material fines and restitution, such as the specialist trading investigation that culminated in an aggregate payment by us of $63.5 million in April 2004.

It is possible that unresolved regulatory investigations, including those that arise in the ordinary course of our business or otherwise, if resolved
adversely to us, could have a material adverse effect on our business, operations and results of operations.

We cannot assure you that
we will be able to detect or prevent all employee misconduct or rule violations.

We are subject to extensive regulation under both
federal and state laws. In addition, the SEC, the NYSE, the NASD, the AMEX, other SROs and state securities commissions require strict compliance with their respective rules and regulations. Employee misconduct that may be difficult to detect could
result in losses. Misconduct by employees could include, among other things, binding us to transactions that exceed authorized limits or present excessive risks, violation of securities laws or exchange rules that have not been detected by the
technological systems installed by the exchanges and us to prevent such violations or hiding from us unauthorized or unsuccessful activities, which, in any case, may result in unknown and unmanaged risks or losses. Employee misconduct could also
involve the improper use or disclosure of confidential information, which could result in regulatory sanctions and serious reputation or financial harm.



24



---

If there are any additional investigations or actions against us, such investigations or actions could
result in settlements, determinations or judgments requiring substantial payments by us, including the costs of defending such investigations or actions, the imposition of substantial sanctions, fines or penalties and the suspension or revocation of
our registration with the SEC as a broker-dealer or our suspension or expulsion as a member firm of the NYSE, the AMEX and the other exchanges on which we operate, in which case we would be unable to operate our business.

It also may be difficult for us to comply with other new or revised legislation or regulations imposed by the SEC, other U.S. or foreign governmental
regulatory authorities and SROs, including the NYSE and the AMEX, pursuant to Regulation NMS and the HYBRID system. The risks of failure to comply with foreign laws and rules will increase as our LSPE and LSPH subsidiaries operate as foreign
broker-dealers. Failure to comply with any of these rules or regulations would have an adverse effect on our business, financial condition and/or operating results. Other changes in the interpretation or enforcement of existing laws and rules by the
SEC, these governmental authorities and SROs also could have an adverse effect on our business, financial condition and/or operating results.

We also are subject to the risks of securities laws liability and related civil litigation.

Many aspects of our business
involve substantial risks of legal liability. A specialist is exposed to substantial risks of liability under federal and state securities laws, other federal and state laws and court decisions, as well as rules and regulations promulgated by the
SEC, the NYSE and the AMEX.

The NYSE and SEC investigation of specialist trading activity, which was settled in April 2004, has also
resulted in the initiation of purported class action and derivative action proceedings against us and certain of our officers and directors in the United States District Court for the Southern District of New York and other proceedings in other
courts, all of which are described under "Item 3Legal Proceedings." In 2004 and early 2005, we also received requests for information from the SEC and the United States Attorneys Office for the Southern District of New York as part of an
industry-wide investigation relating to activities of NYSE floor specialists from 1999 through 2003.

While we deny the allegations of
wrongdoing against us in the actions initiated against us, there can be no assurance as to the ultimate outcome or timing of their resolution. The range of possible resolutions could include determinations and judgments against us or settlements
that could require substantial payments by us, including the costs of defending such investigations and suits, which could have a material adverse effect on our financial condition, results of operations and cash flows.

We also are subject to the risk of civil litigation, employment claims and other actions in the ordinary course of our business operations. For example,
in August 2006, we settled a suit filed by the Equal Employment Opportunity Commission on behalf of a former employee who claimed discrimination on the basis of disability. It is possible that we could incur significant legal expenses in defending
ourselves against such lawsuits or claims. An adverse resolution of any future lawsuits or claims against us could have an adverse effect on our business, financial condition and/or operating results.

We may incur losses as a result of our large balance sheet and ineffective risk management processes
and strategies.

We seek to monitor and control our risk exposure through a variety of separate but complementary financial, credit,
operational, compliance and legal reporting systems. Our trading risk management process seeks to balance our ability to profit from trading positions with our exposure to potential losses. While we employ a broad and diversified set of risk
monitoring and risk mitigation techniques, those techniques and the judgments that accompany their application cannot anticipate every economic and financial outcome or the specifics and timing of such outcomes. Thus, we may, in the course of our
ordinary trading activities, incur losses.

The models that we use to assess and control our risk exposures reflect assumptions about the
degrees of correlation or lack thereof among prices of various asset classes or other market indicators, and in times of market stress or other unforeseen circumstances, previously uncorrelated indicators may become correlated or previously
correlated indicators may move in different directions. Many of our risk management tools are made up of software programs outsourced from third parties. In the past, market movements have at times limited the effectiveness of our hedging strategies
and have caused us to incur significant losses, and they may do so in the future.

Market volatility has been relatively low in recent
years. An increase in volatility would increase our measured or hedged risk, which might cause us to reduce our proprietary positions or to reduce or adapt certain of our business activities. In addition, we have a substantial balance sheet relating
to our growing options, futures and ETF specialists and market-making operations, due primarily to the large positions we take to seed these products and/or manage our risk. In the event the assumptions or quantifications we have taken to seed or
hedge these positions are incorrect, or in the event the market volumes, prices or volatility are not as anticipated, our financial condition could be harmed. In such circumstances, we may not be able to reduce our positions or our exposure in a
timely, cost-effective way or in a manner sufficient to offset the increase in measured risk, which could adversely affect our financial condition and results of operations.

For a further discussion of our risk management policies and procedures, see Quantitative and Qualitative Disclosures About Market Risk in
Part II, Item 7A of this Annual Report on Form 10-K.

We may have insufficient capital in the future and may be unable to
secure additional financing when we need it.

Our business depends on the availability of adequate capital. We cannot be sure that we
will have sufficient capital in the future or that additional financing will be available on a timely basis, or on terms favorable to us. Historically, we have satisfied these needs with internally generated funds, the issuance of subordinated debt
by our operating subsidiaries and the issuance of common stock and notes. While we currently anticipate that our available cash resources will be sufficient to meet our anticipated working capital, regulatory capital and capital expenditure
requirements through at least the next twelve months, we may need to raise additional funds to:



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



26



---

| |  |  | expand or diversify our operations;
| | - |  | -----------------------------------



| |  |  | acquire complementary businesses; or
| | - |  | ------------------------------------



| |  |  | respond to unanticipated capital requirements.
| | - |  | ----------------------------------------------

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

Our revenues may decrease due to changes affecting the economy or changes affecting the securities markets, such as decreased volume, volatility or
liquidity.

Adverse changes affecting the economy and/or the securities markets could result in a further decline in market volatility
or liquidity, thus negatively impacting revenues at our Specialist and Market-Making segment and our Execution and Clearing segment. Many elements of our cost structure do not decline if we experience reductions in our revenues and we may be unable
to adjust our cost structure on a timely basis, or at all, and we could suffer losses.

Increased program trading and lower levels of
volatility on the NYSE over the past three years have negatively affected our results of operations and may adversely affect our operations in the future. Although U.S. equity prices generally recovered from 2003 through 2006, adverse changes in the
economy and the securities markets could return, resulting in:



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



| |  |  | a decline in trading volume on the NYSE, the AMEX and other exchanges;
| | - |  | ----------------------------------------------------------------------



| |  |  | further declines in volatility in the securities markets in which we act as a specialist;
| | - |  | -----------------------------------------------------------------------------------------



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



| |  |  | further increases in claims and litigation.
| | - |  | -------------------------------------------

Whether market and economic conditions will continue to improve and whether we will be able to adequately protect our interests and maintain revenues in the future is uncertain.

Risks associated with our trading transactions could result in trading losses.

A majority of our Specialist and Market-Making segment's revenues are derived from trading by us as principal. We may incur trading losses relating to
these activities, since each trade primarily involves the purchase, sale or short sale of securities for our own account. In any period, we may incur trading losses in a significant number of our specialist stocks, options, futures, ETFs, foreign
currencies and other derivatives for a variety of reasons, including price declines, lower trading volumes and the required performance of our specialist obligations. From



27



---

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 results in an immediate reduction of our revenues and operating results. Our specialist and market-maker trading in options, ETFs, futures,
other derivative instruments and foreign currencies also exposes us to certain additional risks associated with such factors as price fluctuations, foreign exchange currency movements, changes in the liquidity of markets, volatility and counterparty
credit. Although we have adopted and carry out risk management procedures, we cannot be sure that these procedures have been formulated properly to identify or completely limit our risks and, even if formulated properly, we cannot be sure that we
will successfully implement these procedures. As a result, we may not be able to manage our risks successfully or avoid trading losses.

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

Specialist and market-maker rules require us to make unprofitable trades and refrain from making profitable trades.

Our roles as a specialist and market maker, at times, require us to make trades that adversely affect our operating results. In addition, as a specialist
and market-maker, we are at times required to refrain from trading for our own account in circumstances in which it may be to our advantage to trade. For example, we may be obligated to act as a principal when buyers or sellers outnumber each other
and take a position counter to the market, buying or selling shares to support an orderly market in the affected stocks. In addition, specialists currently may not compete with public orders at the same price. By having to support an orderly market,
maintain inventory positions and refrain from trading under some favorable conditions, we are subject to risk. In addition, one consequence of the SEC and the NYSE investigations of NYSE specialist trading practices may be amendments by the NYSE
and, possibly, the AMEX, of the rules, practices and procedures governing our specialist and market-making activities in a manner that could adversely affect our trading revenues.

Derivative transactions may expose us to unexpected risk and potential losses.

We are party to a large number of derivative transactions, many of which are intended to hedge our specialist and market-making risk, including credit
derivatives, that require that we deliver to the counterparty the underlying security, loan or other obligation in order to receive payment. In a number of cases, we do not hold the underlying security, loan or other obligation and may have
difficulty obtaining, or be unable to obtain, the underlying security, loan or other obligation through the physical settlement of other transactions. As a result, we are subject to the risk that we may not be able to obtain the security, loan or
other obligation within the required contractual time frame for delivery. This could cause us to forfeit the payments due to us under these contracts or result in settlement delays with the attendant credit and operational risk as well as increased
costs to the firm.



28



---

Derivative contracts and other transactions entered into with third parties are not always confirmed by
the counterparties on a timely basis. While a transaction remains unconfirmed, we are subject to heightened credit and operational risk, and in the event of a default, we may find it more difficult to enforce the contract.

Failure to comply with net capital and net liquid asset requirements may result in the revocation of our registration with the SEC or our expulsion
from the NYSE and/or the AMEX.

The SEC, the NYSE, the AMEX and various other regulatory agencies have stringent rules with respect to
the maintenance of minimum levels of capital and net liquid assets by securities broker-dealers and specialist firms. Currently, LaBranche & Co. LLC and LSPS are required to maintain minimum combined net liquid assets of approximately
$323.3 million. Failure by any of our broker-dealer and specialist subsidiaries to maintain its required level of net capital and net liquid assets may subject it to suspension or revocation of its SEC registration or suspension or expulsion by
the NYSE and/or the AMEX. If this occurs, we would be unable to operate our business. In addition, a change in these rules, the imposition of new rules or any unusually large capital requirement or charge against the regulatory capital of any of our
broker-dealer subsidiaries could limit those areas of our operations which require intensive use of capital. These rules also could restrict our ability to withdraw capital from our broker-dealer subsidiaries, thus limiting our ability to expand,
diversify or even maintain our present levels of business, pay dividends, repay debt and repurchase shares of our outstanding common stock.

Failure to comply with undertakings set forth in the settlement with the NYSE and SEC could adversely affect us.

In
connection with our 2004 settlement of the NYSE and the SEC investigations concerning our NYSE specialist trading activity, we agreed to, and we are complying with, the following undertakings:



| |  |  | implementation of systems and procedures to ensure appropriate follow up and review with regard to information provided to LaBranche & Co. LLC on a daily
basis by the NYSE with regard to specialists' override of the Principal Inhibitor function, which identifies specialist principal trades that may have been effected while an executable agency order was reflected in the order book on the same side of
the market;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | creation of a committee, including LaBranche & Co. LLC's chief compliance officer and at least two members of senior management, specifically charged with
meeting periodically (no less frequently than monthly) to evaluate specialist rule compliance;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | development and/or enhancement of systems and procedures to track and maintain records identifying the individuals acting as specialist and clerk for each security
at all times throughout each trading day;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | annual certification, through LaBranche & Co. LLC's chief executive officer, that a review has been conducted by the chief compliance officer of trading in
LaBranche & Co. LLC's principal account for the purpose of detecting interpositioning, trading ahead and unexecuted limit order violations;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



29



---

| |  |  | bi-annual assessment of, and reports on, the adequacy of the resources devoted to LaBranche & Co. LLC's compliance function, and devotion of adequate funds
and staffing to the compliance department; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | retention of an independent consultant to review and evaluate LaBranche & Co. LLC's compliance systems, policies and procedures reasonably designed to
ensure that LaBranche & Co. LLC is in compliance with federal securities laws and NYSE rules with regard to specialist trading.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

If we are, in the future, unable to maintain our compliance with any of these undertakings for reasons that we cannot foresee, such failure could have a material adverse effect on our business and our regulatory
compliance structure.

We depend primarily on our specialist and market-making activities, and if they fail to generate revenues as
anticipated, it would adversely affect our financial condition and results of operations.

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



| |  |  | continued growth in the volume of trading and the number of listings on the NYSE, the AMEX and other exchanges;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | being chosen as the specialist for additional listed companies and ETFs;
| | - |  | ------------------------------------------------------------------------



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



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

Over the past few years, a number of alternative trading systems have been developed or emerged. These alternative trading systems may compete with specialists by increasing trading in NYSE-listed and AMEX-listed
securities off the NYSE and the AMEX trading floors. This can be seen in the decrease in the NYSEs percentage of overall U.S. trading volume from approximately 84% in 2002 to approximately 47.2% in 2006. In addition, as described above, the
SEC and the NYSE's market structure rule changes could result in increased trading of NYSE-listed and AMEX-listed securities in electronically-matched orders and thus reduce levels of trading of such securities through specialists.

We cannot be certain that we will be able to retain all of our top listed companies. If we lose a significant number of listed companies, if those listed
companies request a change in their specialist or if the NYSE were to determine that we have failed to fulfill our obligations as



30



---

specialist for a listed company, our registration as the specialist for those listed company could be canceled or suspended. Although we have further
diversified our specialist and market-making operations into additional products and marketplaces, this diversification may not adequately diminish our risk of reliance on certain operations.

We cannot assure you that we will continue to be able to effectively compete in the specialist and market-making industry.

We cannot be sure that we will be able to compete effectively with current or future competitors in the specialist and market-making industry. We obtain
all our new equity listings on the NYSE by going through an allocation process. In this process, either a committee of the NYSE or the listing company chooses the specialist. The competition for obtaining new listing companies is intense. We expect
competition to continue and further intensify in the future. We also compete with significantly larger entities to be the specialist in ETFs traded on the NYSE and the AMEX. Although we have been able to secure a market share of the ETF specialist
business with many of the established ETF issuers, we cannot assure you that our growth in market share will continue as our competitors focus more resources on their ETF specialist business or as market participants enter the ETF market. Some of
our competitors may have significantly greater financial and other resources than we have in both specialist and market-making activities and may have greater name recognition. These competitors may be able to respond more quickly to new or evolving
opportunities and listing company requirements. They also may be able to undertake more extensive promotional activities to attract new listing companies. Our failure to compete effectively would have an adverse effect on our operating results.

We have high debt obligations that can adversely impact our margins and flexibility of operations.

As of December 31, 2006, our total debt outstanding was $490.8 million. Our level of debt could have important consequences, including the
following:



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



| |  |  | our ability to use operating cash flow in other areas of our business may be limited because we dedicate a substantial portion of these funds to service our debt;
and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limitation on our flexibility to adjust to changing market conditions, changes in our industry and economic downturns.
| | - |  | ----------------------------------------------------------------------------------------------------------------------

Our ability to take certain actions may be restricted by the terms of our outstanding indebtedness.

The covenants in the indenture governing our outstanding 9.5% Senior Notes due 2009 and our outstanding 11.0% Senior Notes due 2012, in the aggregate
principal amount of approximately $459. million (collectively, the outstanding senior notes), and subordinated note purchase agreements (under which approximately $6.0 million remains outstanding), as well as any future financing
agreements, may adversely affect our ability to finance future operations or capital needs or to engage in other business activities. These covenants may limit or restrict our ability and the ability of our subsidiaries, under certain circumstances,
to:



| |  |  | incur additional debt;
| | - |  | ----------------------



31



---

| |  |  | pay dividends and make distributions;
| | - |  | -------------------------------------



| |  |  | repurchase our common stock or subordinated indebtedness prior to maturity;
| | - |  | ---------------------------------------------------------------------------



| |  |  | make certain investments;
| | - |  | -------------------------



| |  |  | create liens on our assets;
| | - |  | ---------------------------



| |  |  | transfer or sell assets;
| | - |  | ------------------------



| |  |  | enter into transactions with affiliates;
| | - |  | ----------------------------------------



| |  |  | issue or sell stock of subsidiaries; or
| | - |  | ---------------------------------------



| |  |  | merge or consolidate.
| | - |  | ---------------------

For example,
our ability to take certain actions, such as incurring additional indebtedness (other than certain permitted indebtedness) or making certain restricted payments (such as paying dividends, redeeming stock or repurchasing
subordinated indebtedness prior to maturity), is limited if our consolidated fixed charge coverage ratio, as defined by our debt covenants and calculated on a trailing four-quarter basis, is at or below a threshold of 2.00:1, as more fully described
in Managements Discussion and Analysis of Financial Condition and Results of Operations  Capital Resources. As of December 31, 2006 our consolidated fixed charge coverage ratio was below 2:00:1, and we thus currently are
prohibited from making restricted payments exceeding $15.0 million in the aggregate over the life of the indenture. In addition, under the indenture governing our outstanding senior notes, even if our consolidated fixed charge coverage
ratio is 2.00:1 or greater, we cannot make any such restricted payments if doing so will cause our cumulative restricted payments since May 18, 2004 to be greater than the sum of (A) 50.0% of our cumulative
consolidated net income since July 1, 2004 (or, if such calculation is a loss, minus 100.0% of such loss) and (B) 100.0% of the net cash proceeds received from any issuance or sale of our capital stock since July 1, 2004 and certain
other amounts. As of December 31, 2006, this covenant prevented us from making restricted payments in excess of $104.0 million. Although we have not made any restricted payments since May 18, 2004, we cannot be sure if, when or to what
extent the covenants in the indenture will prevent us from making restricted payments in the future.

In addition, our LaBranche &
Co. LLC subsidiary has approximately $6.0 million principal amount outstanding subordinated indebtedness. The note purchase agreement governing this subordinated indebtedness requires LaBranche & Co. LLC to comply with certain financial
ratios. LaBranche & Co. LLC's ability to comply with these ratios may be affected by events beyond our or its control. If any of the covenants in this agreement are breached, or if LaBranche & Co. LLC is unable to comply with
required financial ratios, we or it may be in default under such agreements. A significant portion of this indebtedness then may become immediately due and payable.

We are not certain, if we are required accelerated payments under our indebtedness, including payments on
our outstanding senior notes, if such acceleration would adversely affect our business.

We may not be able to generate sufficient cash
flows to meet our debt service obligations, including payments on the outstanding senior notes.

Our ability to generate sufficient
cash flows from operations to make scheduled payments on our debt obligations will depend on our future financial performance, which will be, to an extent, subject to general economic, financial, competitive, regulatory and other factors that are
beyond our control.

We cannot provide assurance that our business will generate sufficient cash flows or that future borrowings will be
available to us in an amount sufficient to enable us to pay our debt, including the outstanding senior notes, or to fund our other liquidity needs. If our future cash flows from operations are insufficient to pay our obligations as they mature or to
fund our liquidity needs, we may be forced to sell assets, obtain additional equity capital or restructure or refinance all or a portion of our debt, including the outstanding senior notes, on or before maturity. We cannot assure you that we will be
able to repay or refinance our debt, including the outstanding senior notes, on a timely basis or on satisfactory terms, if at all.

We
may not be able to finance a change of control offer required by the indenture governing the outstanding senior notes.

If we were to
experience a change of control, we would be required to offer to repurchase all outstanding senior notes then-outstanding, as well as all of our then-outstanding 12.0% senior subordinated notes due 2007, in the aggregate principal amount of
approximately $13.6 million (the 2007 notes), in each case at a price equal to 101.0% of their principal amount, plus accrued and unpaid interest, if any, to the date of repurchase. This purchase requirement may delay or make it harder
for others to obtain control of us. If a change of control were to occur, it is possible that we would not have sufficient funds to repurchase these notes or that restrictions in LaBranche & Co. LLC's subordinated note purchase agreements
would not allow such repurchases. If we do not have sufficient funds at the time of a repurchase obligation or cannot meet any obligations under the subordinated note purchase agreements, the indenture governing the outstanding senior notes, or the
indenture governing the 2007 notes, we would be forced to seek additional third-party financing. However, it is possible that we would not be able to obtain such financing on favorable terms, or at all.

Our success depends on our ability to accurately process and record our transactions, and any failure to do so could subject us to losses.

Our specialist, market-making and clearing and execution activities require us to accurately record and process a very large number of
transactions on a daily basis. Any failure or delay in recording or processing transactions could cause substantial losses for brokers, their



33



---

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

Any information or communication systems failure or decrease in
information or communications systems performance that causes interruptions in our operations could have an adverse effect on our business, financial condition and/or operating results. Our systems may fail as a result of a hardware, software, power
or telecommunications failure. In addition, our offices are located in close proximity to the site of the September 11, 2001 terrorist attacks on the World Trade Center. The aftermath of the attacks on the World Trade Center required us to
close our operations and temporarily operate from our disaster recovery site. The NYSE also was forced to stop operating for four consecutive trading days, which caused our operations to halt. It is possible that additional terrorist attacks or acts
of war may occur in the future and that such attacks could compromise or disable our systems. Although we have established back-up disaster recovery centers in New Jersey and New York and have an overall business continuity plan in the event of
another disaster, these measures may not be effective in preventing an interruption of our business.

We also are dependent on the proper
and timely function of complex information and communications systems maintained and operated by or for the NYSE, the AMEX and clearing and depositary institutions. Failures or inadequate or slow performance of any of these systems could adversely
affect our ability to operate and complete trades. The failure to complete trades on a timely basis could subject us to losses and claims for losses of brokers and their customers.

If we lose the services of our key personnel or cannot hire additional qualified personnel, our business will be harmed.

Our future success depends on the continued service of key employees, particularly George M.L. LaBranche, IV, our Chairman, Chief Executive Officer and
President. The loss of the services of any of our key personnel or the inability to identify, hire, train and retain other qualified personnel in the future could have an adverse effect on our business, financial condition and/or operating results.
Competition for key personnel and other highly qualified management, trading, compliance and technical personnel is intense. We cannot assure you that we will be able to attract or retain highly qualified personnel in the future.

Our current and prospective employees may experience uncertainty about their future roles with us and our business prospects. This uncertainty may
adversely affect our ability to attract and retain key personnel, which would adversely affect our business and results of operations.

We may have difficulty successfully managing our growth.



34



---

Our business has grown since 1997, primarily due to acquisitions and organic growth through the continued
expansion of our specialist and market-making operations. The growth of our business has increased the demands upon our management and operations. This growth has required, and will continue to require, an increase in investment in management
personnel, financial and management systems and controls and facilities. The scope of procedures for assuring compliance with applicable rules and regulations, including SOX, has changed as the size and complexity of our business has increased.
Although the size of our workforce significantly declined in 2006 and early 2007, many of our SOX policies, processes and controls have not, which means we have fewer employees to ensure these controls are completed. We have implemented formal
compliance procedures that are regularly updated. Our future operating results will depend on our ability to continue:



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



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



| |  |  | to raise additional capital if and when needed;
| | - |  | -----------------------------------------------



| |  |  | to effectively deploy assets, capital or workforce;
| | - |  | ---------------------------------------------------



| |  |  | to maintain strong relationships with, and attract new, listed companies; and
| | - |  | -----------------------------------------------------------------------------



| |  |  | to retain and incentivize our employees.
| | - |  | ----------------------------------------

Three of our current or former executive officers are in a position to substantially affect matters requiring a stockholder vote.

Certain of our current and former managing directors who currently own a significant amount of our outstanding common stock have entered into a stockholders' agreement under which they have agreed, among other things, that their shares of
our common stock will be voted, for as long as they own their shares, as directed by a majority vote of George M.L. LaBranche, IV, our Chairman, Chief Executive Officer and President, Alfred O. Hayward, Jr., our executive officer, director and Chief
Executive Officer of LaBranche & Co. LLC, and James G. Gallagher, a former executive officer and director. Accordingly, these individuals have the ability to substantially influence the outcome of most matters requiring approval by our
common stockholders. These matters include the election and removal of directors and the approval of any merger, consolidation or sale of all or substantially all our assets. This concentration of ownership could have the effect of delaying,
deferring or preventing a change in control, a merger or consolidation, a takeover or another business combination.

Risks Associated
with the NYSE/Archipelago Merger, Proposed NYSE Regulation/NASD Merger and Pending NYSE/Euronext Merger

The value of the NYSE
Group stock we received in the NYSE/Archipelago merger, as well as the NYSE Euronext stock we expect to receive in the pending NYSE/Euronext merger, may significantly lose value.



35



---

In connection with the March 2006 NYSE/Archipelago merger, we received approximately 3.1 million
shares of NYSE Group common stock in exchange for 39 NYSE memberships which we previously owned. Under the merger agreement, there are restrictions on the sale of the NYSE Group shares following the merger. As provided in the agreement, one-third of
these NYSE Group shares will be released from these sale restrictions on each of March 8, 2007, 2008 and 2009. There is a risk that there could be a significant drop in the value of the NYSE Group stock prior to the time we are able, if we
choose to monetize the consideration we received in exchange for the NYSE memberships we held prior to the NYSE/Archipelago merger. We currently mark our NYSE Group shares to market, subject to applicable discounts due to restrictions on transfer,
and when the restrictions lapse on our NYSE Group shares, we will no longer discount their market value. Any substantial drop in the value of NYSE Group shares we do not monetize could require us to consider whether such drop in value has created an
impairment of our intangible assets. Such an impairment, if any, would adversely affect our financial results for the fiscal period in which an impairment occurs. In the pending NYSE/Euronext merger, we anticipate that we will exchange our
3.1 million NYSE Group shares (or the portion of such shares which we then own) into a like number of shares of NYSE Euronext common stock. Our gains or losses in our ownership of those shares will be dependent on the market price of NYSE
Euronext shares generally. Therefore, we could report significant losses or gains based on the market price of that stock on the last day of a reporting period.

The regulatory environment following the NYSE/Archipelago merger, as well as the NYSE/Euronext merger, including NYSE Regulations proposed merger with NASD Regulation, could change and thereby adversely
affect our compliance and strategic efforts.

NYSE Regulation currently performs the regulatory function for the NYSE and the Pacific
Stock Exchange. The NYSE Group has stated that technology is playing a greater role in trading, compliance and regulation. It is possible that these factors could cause regulatory or technological errors, especially if NYSE Regulation is unable to
adequately self-fund its operations. On January 21, 2007, a majority of the member firms of each entity approved a consolidation of the NASDs and NYSEs regulatory arms. The consolidation will result in a single regulatory division
that will be responsible for member examination, enforcement, arbitration and mediation, as well as market regulation for the NYSE, NASDAQ, AMEX, ISE and Chicago Climate exchanges. This combined regulatory division is expected to begin operation in
the second quarter of 2007. This environment could produce additional regulatory scrutiny, which could cause us to expend additional resources to monitor and enhance our compliance with NYSE, AMEX and other exchange rules. We also may be required to
expend substantial resources to coordinate our technological compliance systems with the new technological requirements of the NYSE, AMEX and other markets, which could increase our overall Specialist and Market-Making segment operating expenses and
adversely affect our operating results.

The role of the specialist on the NYSE may substantially change following the NYSE/Archipelago
and NYSE/Euronext mergers and we may not be able to timely adapt.

Although senior NYSE officials have continued to publicly state that
there will continue to be an auction market with a central point of sale on the NYSE following the merger, and that specialists will continue to play an integral role in making a fair and orderly market and



36



---

providing liquidity, there is speculation that large issuers stocks will trade entirely electronically with minimal participation by specialists. We
may not be able to anticipate or adequately and effectively deploy capital, workforce and technology to respond to such a change. Although we have expended considerable resources to enable us to adapt to such a situation, we may not be able to
timely or successfully do so. Any failure by us to anticipate, respond or adapt to a changing market structure in the wake of the mergers could adversely affect our results of operations and financial condition.

The NYSE Group may not achieve the anticipated cost savings, technology improvements, growth opportunities and other benefits anticipated from the
merger transactions, which could adversely affect the operations of the NYSE specialist firms following the mergers.

Some of the
stated purposes of the NYSEs merger with Archipelago and pending merger with Euronext are cost savings, the ability to compete with an increasingly electronic marketplace, potential market growth opportunities and other synergies. Prior to the
mergers, these entities operated as separate companies with different goals, technology, infrastructures and market structures. The success of these mergers will depend, in part, on the ability to achieve these cost savings, efficiencies and
technological and product advances. If the NYSE is not able to successfully achieve these objectives, the anticipated cost savings, technological and revenue growth and synergies may not be realized fully or at all, or may take longer to realize
than expected. In such event, the new NYSE may lose listed companies, exchange-based trading market share and additional product lines and order flow. To the extent the NYSE is unable to attract new listed companies or products or loses existing
listed companies and products, our financial results and operations could be materially adversely affected.

None.



|Item 2. | PROPERTIES.

Our offices are located at One
Exchange Plaza, New York, New York, where we lease approximately 36,000 square feet under two separate leases expiring in January 2008. We also lease approximately 48,000 square feet at 33 Whitehall Street, New York, New York under a lease expiring
February 2017. We also lease three trading posts on the floor of the NYSE and approximately 8,100 square feet of additional space at locations in New York, New Jersey and Boston under leases expiring between June 2007 and September 2012. In
addition, we lease approximately 1,000 square feet in Amsterdam, The Netherlands, under a lease expiring in April 2009, a workstation (approximately 25 square feet) in London, England, under a month-to-month operating lease, and approximately 133
square meters in Hong Kong under a lease expiring in November 2008. 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 near future.

|Item 3. | LEGAL PROCEEDINGS.
|------- | ------------------

Specialist Trading
Investigations. On March 30, 2004, LaBranche & Co. LLC and other NYSE specialist firms entered into agreements with the SEC and NYSE to settle the SEC and NYSE investigations concerning alleged improper specialist trading practices
by specialists on the NYSE. Pursuant to the settlement, LaBranche & Co. LLC consented, without admitting or denying any wrongdoing, to an SEC order instituting administrative cease-and-desist proceedings, making findings, and imposing
remedial sanctions and a cease-and-desist order. The SECs findings, neither admitted nor denied, included violations by LaBranche & Co. LLC of Section 11(b) of the Exchange Act and Rule 11b-1 promulgated thereunder, NYSE Rules
104, 92, 123B, 401 and 342, and Section 15(b)(4)(E) of the Exchange Act. The Section 15(b)(4)(E) finding includes a failure reasonably to supervise individual specialists who, the finding states, violated Section 10(b) of the Exchange
Act and Rule 10b-5 promulgated thereunder with respect to transactions in six particular stocks. Pursuant to the settlement, LaBranche & Co. LLC paid $41.6 million in restitution and $21.9 million in a civil money penalty, which we accrued
for the year ended December 31, 2003, in connection with trades that occurred during the years 1999 through 2003 and has agreed to undertakings stated in the SECs order.

NYSE, civil and/or criminal charges have been pursued against a number of individuals employed or formerly employed as specialists at the five largest
NYSE specialist firms, including employees and former employees of LaBranche & Co. LLC.

In re LaBranche Securities
Litigation. On or about October 16, 2003 through December 16, 2003, nine purported class action lawsuits were filed by purchasers of our common stock in the United States District Court for the Southern District of New York, including
Sofran v. LaBranche & Co Inc., et al., No. 03 CV 8201, Semon v. LaBranche & Co Inc., et al., No. 03 CV 8255, Haug v. LaBranche & Co. Inc., et al., No. 03 CV 8265, Labul v. LaBranche & Co Inc., et
al., No. 03 CV 8365, Murphy v. LaBranche & Co Inc., et al., No. 03 CV 8462, Strain v. LaBranche & Co Inc., et al., No. 03 CV 8509, Yopp v. LaBranche & Co Inc., et al., No. 03 CV 8783, Ferris v.
LaBranche & Co Inc., et al., No. 03 CV 8806, and Levin v. LaBranche & Co Inc., et al., No. 03 CV 8918. On March 22, 2004, the court consolidated these lawsuits under the caption In re LaBranche Securities Litigation,
No. 03 CV 8201. The court named the following lead plaintiffs: Anthony Johnson, Clyde Farmer, Edwin Walthall, Donald Stahl and City of Harper Woods Retirement System.

On June 7, 2004, plaintiffs filed a Consolidated Class Action Complaint. On July 12, 2004, plaintiffs filed a Corrected Consolidated Class
Action Complaint. Plaintiffs allege that they represent a class consisting of persons and entities that purchased or otherwise acquired our common stock during the period beginning on August 19, 1999 and concluding on October 15, 2003.
Plaintiffs allege that we, LaBranche & Co. LLC, and certain of our and/or LaBranche & Co. LLCs past or present officers and/or directors, including George M.L. LaBranche, IV, William J. Burke, III, James G. Gallagher, Alfred
O. Hayward, Jr., Robert M. Murphy and Harvey S. Traison, violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder and Section 20(a) of the Exchange Act by failing to disclose the alleged improper specialist trading
that was the subject of the specialist trading investigations described above. Plaintiffs also allege that Mr. Gallagher violated Section 20A of the Exchange Act and two other of our past or present officers and/or directors,
S. Lawrence Prendergast and George E. Robb, Jr., also violated Section 20(a) of the Exchange Act. Plaintiffs seek unspecified money damages, attorneys fees and reimbursement of expenses.



38



---

On December 12, 2005, motions to dismiss were granted in part and denied in part. The court
dismissed the Section 10(b) claims in their entirety against Messrs. Burke, Gallagher and Traison, dismissed the Section 10(b) claims for the period August 19, 1999 through December 30, 2001 against Messrs. LaBranche, Murphy and
Hayward, and dismissed the Section 20A claim against Mr. Gallagher.

In re NYSE Specialists Securities Litigation. On or
about October 16, 2003 through December 16, 2003, four purported class action lawsuits were brought by persons or entities who purchased and/or sold shares of stocks of NYSE listed companies for which LaBranche & Co. LLC and any
other NYSE specialist firm acted as specialist, including Pirelli v. LaBranche & Co Inc., et al., No. 03 CV 8264, Marcus v. LaBranche & Co Inc., et al., No. 03 CV 8521, Empire v. LaBranche & Co Inc., et al.,
No. 03 CV 8935, and the California Public Employees Retirement System (CalPERS) v. The New York Stock Exchange, Inc., et al., No. 03 CV 9968. On March 11, 2004, a fifth action asserting similar claims, Rosenbaum Partners, LP v.
The New York Stock Exchange, Inc., et al., No. 04 CV 2038, was filed in the United States District Court for the Southern District of New York by an individual plaintiff who does not allege to represent a class. On May 27, 2004, the court
consolidated these lawsuits under the caption In re NYSE Specialists Securities Litigation, No. CV 8264. The court named the following lead plaintiffs: California Public Employees Retirement System (CalPERS) and Empire Programs,
Inc.

On September 15, 2004, plaintiffs filed a Consolidated Complaint for Violation of the Federal Securities Laws and Breach of
Fiduciary Duty alleging that they represent a class consisting of all public investors who purchased and/or sold shares of stock listed on the NYSE from October 17, 1998 to October 15, 2003. Plaintiffs allege that we, LaBranche &
Co. LLC, Mr. LaBranche, and other NYSE specialist firms and their respective parents and affiliates violated Section 10(b), Rule 10b-5 and Section 20(a) by failing to disclose the alleged improper specialist trading that was the
subject of the specialist trading investigations described above, improperly profiting on purchases and/or sales of NYSE-listed securities and breaching and/or aiding and abetting breaches of fiduciary duty. Plaintiffs also name the NYSE as a
defendant. Plaintiffs seek unspecified money damages, restitution, forfeiture of fees, commissions and other compensation, equitable and/or injunctive relief, including an accounting of and the imposition of a constructive trust and/or asset freeze
on trading proceeds, and attorneys fees and reimbursement of expenses.

On December 12, 2005, defendants motion to dismiss
was granted in part and denied in part. The court dismissed plaintiffs Section 10(b) and Section 20(a) claims against all defendants for conduct that occurred before January 1, 1999 and dismissed plaintiffs breach of
fiduciary duty claims against all defendants. The court also dismissed all claims against the NYSE and certain claims against certain parents and affiliates of specialists other than LaBranche & Co. LLC.

On February 2, 2006, plaintiffs filed an Amended Consolidated Complaint for Violation of the Federal Securities Laws and Breach of Fiduciary Duty,
adding Robert A. Martin as a plaintiff. This complaint is otherwise identical to plaintiffs Consolidated Complaint for Violation of the Federal Securities Laws and Breach of Fiduciary Duty.

On February 22, 2007, the court removed Empire Programs, Inc. as co-lead plaintiff, leaving CalPERS as the sole lead plaintiff.

Brown. On or about November 6, 2003, a purported shareholder derivative action, Brown v.
George M. L. LaBranche IV, et al., No. 03 603512, was filed by Norman and Florence Brown, who purport to be two of our shareholders, and who purport to act on behalf of us, against certain of our past or present directors and officers,
including Messrs. LaBranche, Hayward, Murphy and Traison and Thomas E. Dooley, E. Margie Filter (who is deceased), James G. Gallagher, David A. George, Donald E. Kiernan, S. Lawrence Prendergast and George E. Robb, Jr., in the Supreme Court of the
State of New York, New York County. Plaintiffs allege breaches of fiduciary duty arising out of statements by us concerning our specialist trading business that are alleged to have been false and misleading because we failed to disclose alleged
violations of NYSE rules. According to plaintiffs, [a]t least a majority of the Individual Defendants had knowledge of, or were reckless in not knowing of these false and misleading statements and the improper transactions concealed by
such statements, and failed to establish and maintain adequate policies, systems and procedures reasonably designed to detect and prevent such improper transactions. Plaintiffs seek damages, return of all compensation received by the
defendants for periods during which they allegedly breached their fiduciary duties, an order requiring implementation of corrective measures to prevent repetition of the alleged wrongful conduct, and attorneys fees and reimbursement of
expenses.

On November 8, 2004, the court dismissed the action due to plaintiffs failure to make a pre-litigation
demand. The courts decision states that the dismissal is without prejudice to the bringing of a new action, if a pre-suit demand is either rejected or not considered within a reasonable amount of time.

On January 31, 2005, plaintiffs made a demand, alleging improper transactions in connection with [LaBranche & Co. LLCs] role as
a specialist on the New York Stock Exchange and further alleging that the Board of Directors breached its fiduciary duties by . . . failing to exercise reasonable and prudent supervision over the management policies, practices,
controls, and financial affairs of LaBranche, and demanding the following: (1) the appointment of new independent directors who will form a special committee to investigate the alleged managerial, financial, trading and accounting
improprieties, (2) modification of the definition of outside director, (3) separation of the office of chairman and chief executive officer and the election by outside directors of an outside director to serve as chairman,
(4) the special committee must seek restitution and/or monetary damages on behalf of the Company, by lawsuit if necessary, from Messrs. LaBranche, Burke, Dooley, Gallagher, George, Hayward, Kiernan, Murphy, Prendergast, Robb and
Traison and Ms. Filter and any other current or former officer, director or employee, for any and all costs incurred by the Company as a result of the alleged improprieties including, but not limited to, any damages incurred as a result
of the federal securities lawsuits, (5) an investigation by outside auditors of accounting and controls, following which our board must ensure that any and all deficiencies or weaknesses in the Companys
accounting and controls are promptly remedied, (6) creation of a chief ethics officer position and mandatory ethics training, and (7) a recommendation by the special committee of the resignation or dismissal from office of any
and all officers, directors or employees found to have breached any fiduciary duty to the Company, or any law, regulation or internal Company rules. The letter states that the Browns counsel intend to file a shareholder
derivative complaint on behalf of the Browns and for the benefit of LaBranche if, after the expiration of ninety (90) days from the date of this demand, the Board has not responded to the demand or has otherwise failed to satisfy controlling
law.



40



---

On April 22, 2005, our Board of Directors determined to refuse the demand.

On September 7, 2006, Ms. Brown filed a motion for leave to file an amended shareholder derivative complaint alleging that her demand was
wrongfully refused and asserting the same claims previously asserted in the action filed on November 6, 2003.

Henik/Lewis. On
or about February 1, 2005 and March 30, 2005, two purported shareholder derivative actions, Henik v. LaBranche, et al., No. 05 CV 1087 and Lewis v. LaBranche, et al., No. 05 CV 3165, were filed by Diane Henik and Guy C. Lewis,
who purport to be two of our shareholders, and who purport to act on behalf of us, against certain of our past or present directors and officers, including Messrs. LaBranche, Burke, Dooley, Gallagher, George, Hayward, Kiernan, Murphy, Prendergast,
Robb and Traison and Ms. Filter, in the United States District Court for the Southern District of New York. On April 15, 2005, the Henik and Lewis actions were consolidated. On June 14, 2005, the plaintiffs filed an amended
consolidated complaint. The amended complaint alleges breaches of fiduciary duty by the defendants in the case (other than Ms. Filter, who is not named in the amended complaint) arising out of alleged improper specialist trading and violations
of NYSE rules by LaBranche & Co. LLC. According to plaintiffs, the defendants engaged in numerous acts, and on some occasions, failed to act, both of which caused LaBranche to suffer damages, were extremely reckless with
respect to LaBranches internal controls, its corporate governance practices, and their own formal oversight responsibility, it [is] likely that some or all defendants actually directed, knew of, acquiesced after the
fact, or could have easily discovered the alleged improper trading, there were numerous red flags . . . that were deliberately ignored that suggest that the Board actually knew of the misconduct alleged herein or that
could have alerted a conscientious director that something was amiss, and that the defendants either knowingly breached their fiduciary duties to LaBranche and its shareholders, or at the very least, engaged in extremely reckless
conduct which also was a breach of fiduciary duties. Plaintiffs seek unspecified money damages, attorneys fees and reimbursement of expenses.

On June 30, 2006, the Court entered an order dismissing the Henik and Lewis actions.

On
August 28, 2006, Diane Henik made a demand, alleging breaches of fiduciary duties by our directors and certain executive officers and demanding that the Board commence a civil action against certain past or present
directors and officers to recover for the benefit of the Company the amount of damages sustained by the Company as a result of their breaches of fiduciary duties and all bonuses, restricted stock, stock option, and other incentive
compensation recoverable pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 and/or Delaware law. The letter further states that [i]f within a reasonable period of time after receipt of this letter the Board has not commenced
an action as demanded herein, Ms. Henik will commence a shareholder derivative action on behalf of the Company seeking appropriate relief.

On October 19, 2006, our Board of Directors determined to refuse the demand.

NASD/AMEX Notice of
Disciplinary Action. On December 15, 2004, LaBranche & Co. LLC received a notice from the NASD Amex Regulation Division stating a preliminary



41



---

determination to seek disciplinary action against LaBranche & Co. LLC for violations of certain federal securities laws and the Amex Constitution
and Rules, including Sections 10(b), 9A and 17(a) of the Exchange Act, in connection with manual book freezes effected in one of LaBranche & Co. LLCs Amex specialist stocks during the period March 8, 2004 through October 21,
2004. Prior to receiving this notice, we had determined that the individual specialist responsible for the book freezes failed to adhere to company policy and had terminated that employee. We submitted a response to the staff of the NASD Amex
Regulation Division in January 2005 setting forth the reasons why disciplinary action should not be brought against LaBranche & Co. LLC and we are cooperating with the NASD Amex Regulation Division in this matter.

We believe that the claims asserted against us by the plaintiffs in the pending proceedings described above are without merit, and we deny all
allegations of wrongdoing. There can be no assurance, however, as to the outcome or timing of the resolution of these proceedings. We therefore are unable to estimate the amount or potential range of any loss that may arise out of these proceedings.
The range of possible resolutions could include determinations and judgments against us or settlements that could require substantial payments by us that could have a material adverse effect on our financial condition, results of operations and cash
flows.

In addition to the proceedings described above, we have been the target, from time to time, of various claims, lawsuits and
regulatory actions incidental to the ordinary course of our business. While the ultimate outcome of those claims, lawsuits and regulatory actions which currently are pending cannot be predicted with certainty, we believe, based on our understanding
of the facts of these claims, proceedings and regulatory actions, that their ultimate resolution will not, in the aggregate, have a material adverse effect on our financial condition, results of operations or cash flows.

Regulation G Requirement: Reconciliation of Non-GAAP Financial Measures Excluding

Corporate Equities, Not readily Marketable

(all data in thousands, except per share data)

(unaudited)

In evaluating the Companys financial performance, management reviews results from operations, excluding non-operating items. Pro-forma earnings per share is a non-GAAP (generally accepted accounting principles)
performance measure, but the Company believes that it is useful to assist investors in gaining an understanding of the trends and operating results for the Companys core business. Pro-forma earnings per share should be viewed in addition to,
and not in lieu of, the Companys reported results under U.S. GAAP.

The following is a reconciliation of U.S. GAAP results to pro-forma results for
the periods presented:

|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 set forth in Item 1A of this annual report. 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.

Executive Overview

The equity and equity derivative
trading business is continuing to experience significant change. In December 2006 and January 2007, the NYSE, AMEX and other auction-based exchanges implemented new trading systems in which the markets have become almost completely electronic. These
initiatives were undertaken in order to comply with Regulation NMS, expected to be effective in March 2007. In addition, decimalization, sector and index trading strategies and a decline in block trading have led to increased program trading and a
decline in average order size on the NYSE and other exchanges, which reduces our ability to participate in certain trades.

The NYSEs
new HYBRID market model has had the most significant impact on our role as a specialist. The HYBRID model is expected to allow specialists to interact in a fast and more automated market. Most of the trades which had been executed by us
as agent are now being matched electronically, and we are now inserting our capital and adding liquidity to the market electronically, rather than manually, except in certain break-out situations. Although these changes affect the way in
which stocks are traded, many elements of the central auction market are preserved. Even with the completed NYSE/Archipelago merger, the HYBRID model and SECs Regulation NMS initiatives, senior NYSE officials have publicly stated that there
will continue to be an auction market with a central point of sale. They have also stated that specialists will continue to play an integral role in providing liquidity and will continue to have an affirmative obligation to make a fair and orderly
market. A specialists primary role is to provide liquidity by committing capital when market imbalances occur, and we believe that technology cannot eliminate these market imbalances. Accordingly, we anticipate that specialists will continue
to play an important role in stock trading but will do so in a more electronic environment.

We are committed to providing liquidity and
improving market quality. Even though our participation rate initially has declined from pre-HYBRID levels, we believe the trading tools we are developing may result in higher participation rates over time along with opportunities to increase
revenues. Testing on our new advanced HYBRID technology on a pilot basis indicates that our participation rates can increase. The new technology, which we have been developing for the past three years, is being deployed in stages with the goal of
meaningful implementation

---

in 2007. We expect to adjust these technologies on an ongoing basis, and anticipate that they will enable us to increase the liquidity of our markets. The
financial results of our specialist and market-making business are highly dependent on trading volumes and volatility. As volumes grow, we believe market volatility will return as well, which will enable us to participate as principal in more
transactions in our specialist and market-making operations.

We have significantly cut costs throughout our organization through the
reduction of legal, professional and exchange fees, the mitigation of compensation costs through restructuring and automation. We have reduced the legacy costs of operating a manual market by reducing our headcount by 126 employees during the fourth
quarter of 2006 and January 2007. We also are examining our opportunities relating to the retirement of outstanding debt with the goal of reducing our fixed charge interest expense.

One of the other things on which we are focusing is our ability to quote electronically in different marketplaces simultaneously so that we are able to
get our quotes and disseminate our interest in different marketplaces.

Structured products such as ETFs continue to grow in popularity.
ETFs which have some characteristics similar to sector and index funds trade continually throughout the day on an exchange. The liquidity and flexibility of being exchange-traded has led to substantial growth in these products. ETF assets grew to
approximately $422.0 billion as of January 31, 2007 from $296.0 billion as of December 31, 2005. We believe that the growth in these products will continue as investors seek to lower investment costs, manage tax liability and hedge
portfolio risks. It is our intention to continue to work with ETF issuers as they launch new products and to provide added liquidity in ETF trading.

We also believe the trading of options, indexes and other products will follow the pattern of cash equities. The products that require little price discovery and negotiation will default to an electronic matching
facility while the more complex and illiquid products will continue to rely on specialists and lead market-makers to effect trades.

We
expect the first tranche of our 3.1 million NYX shares to become unrestricted on March 7, 2007. This event will increase the assets constituting regulatory capital in our NYSE specialist and execution and clearing businesses. The combined
liquidity adjustments from the NLA reduction and elimination of the restrictions on our NYX shares will result in approximately $150 million of additional free cash over the first two quarters of 2007 before our debt servicing payments, based on the
closing market price per share of NYX stock on February 28, 2007. Our free cash at December 31, 2006 was approximately $149 million.

New
Accounting Developments

Employee Incentive Plans

We adopted the fair value recognition provisions for share-based awards pursuant to SFAS No. 123(R) effective January 1, 2006. Please refer to Footnote 7, Employee Incentive Plans of our
consolidated financial statements in this report for additional information and disclosure.

Accounting for Tax Uncertainties

In July 2006, the FASB issued Interpretation No. 48 Accounting for Uncertainty in Income Taxes (FIN 48). FIN 48 clarifies the
accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on de-recognition, measurement, classification,
interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 will be effective beginning in the first quarter of 2007. We have evaluated the potential impact of FIN 48, and at this time, we believe that our contingent tax
reserve and current and deferred income taxes are adequately stated in conformity with FAS 109 and FIN 48.

Fair Value Measurements

In September 2006, the FASB issued SFAS No. 157, Fair Value Measurements (SFAS 157). SFAS 157 defines fair
value, establishes a framework for measuring fair value and enhances disclosures about fair value measurements required under other accounting pronouncements, but does not change existing guidance as to whether or not an instrument is carried at
fair value. SFAS 157 nullifies the guidance in EITF 02-3 which precluded the recognition of a trading profit at the inception of a derivative contract, unless the fair value of such derivative is obtained from a quoted market price, or other
valuation technique incorporating observable market data. SFAS 157 also precludes the use of a liquidity or block discount, when measuring instruments traded in an active market at fair value. SFAS 157 requires that costs related to acquiring
financial instruments carried at fair value should not be capitalized, but rather should be expensed as incurred. SFAS 157 also clarifies that an issuers credit standing should be considered when measuring liabilities at fair value. SFAS 157
is effective for financial statements issued for fiscal years beginning after November 15, 2007, with earlier application permitted and encouraged. SFAS 157 must be applied prospectively, except that the provisions related to block discounts
and the guidance in EITF 02-3 are to be applied as a one time cumulative effect adjustment to opening retained earnings in the first interim period for the fiscal year in which SFAS 157 is initially applied. We are currently evaluating the potential
impact, if any, that the adoption of SFAS 157 will have on our consolidated financial statements.

Accounting for Fair Value Option for Financial Assets and Financial Liabilities

In February 2007, the FASB issued SFAS No. 159, Accounting for Fair Value Option for Financial Assets and Financial Liabilities Employers
(SFAS 159). SFAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate
volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. We currently report the majority of our financial assets and liabilities at fair value in
compliance with industry guidelines for brokers and dealers in securities. We have a significant investment in intangibles and goodwill as well as public debt which is not accounted for at fair value. We believe SFAS 159 exempts intangible assets
and goodwill from fair value reporting. We currently are evaluating the potential impact that the adoption of SFAS 159 will have on our financial statements.

Critical Accounting Estimates

Goodwill and Other Intangible Assets

We determine the fair value of each of our reporting units and the fair value of each reporting units goodwill under the provisions of Statement of
Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets. In determining fair value, we use standard analytical approaches to business enterprise valuation (BEV), such as the market
comparable approach and the income approach. The market comparable approach is based on comparisons of the subject company to similar companies engaged in an actual merger or acquisition or to public companies whose stocks are actively traded. As
part of this process, multiples of value relative to financial variables, such as earnings or stockholders equity, are developed and applied to the appropriate financial variables of the subject company to indicate its value. The income
approach involves estimating the present value of the subject companys future cash flows by using projections of the cash flows that the business is expected to generate, and discounting these cash flows at a given rate of return. Each of
these BEV methodologies requires the use of management estimates and assumptions. For example, under the market comparable approach, we assigned a certain control premium to the public market price of our common stock as of the valuation date of our
2006 year-end impairment test, in estimating the fair value of our specialist reporting unit. Similarly, under the income approach, we assumed certain growth rates for our revenues, expenses, earnings before interest, income taxes, depreciation and
amortization, returns on working capital, returns on other assets and capital expenditures, among others. We also assumed certain discount rates and certain terminal growth rates in our calculations. For our year-end 2006 goodwill impairment tests,
we engaged an independent business valuation firm to assist us in our BEV analyses. Given the subjectivity involved in selecting which BEV approach to use and in determining the input variables for use in our analyses, it is possible that a
different valuation model and the selection of different input variables could produce a materially different estimate of the fair value of our goodwill.

We review the reasonableness of the carrying value of our goodwill on an annual calendar basis (i.e., December 31) unless an event or change in circumstances requires an interim reassessment of impairment. During
2006, there were no interim changes in circumstances that



49



---

necessitated goodwill impairment testing prior to our annual required testing of goodwill. As a result of our analysis of the above-mentioned factors for the
year ended December 31, 2006, with the assistance of the independent business valuation firm, we determined that there was no impairment of our goodwill under SFAS No. 142. We cannot provide assurance that future goodwill impairment
testing will not result in impairment charges in subsequent periods.

Another of our intangible assets, as defined under SFAS No. 142,
is our trade name. We determine the fair value of our trade name by applying the income approach using the royalty savings methodology. This method assumes that the trade name has value to the extent we are relieved of the obligation to pay
royalties for the benefits received from it. Application of this methodology requires estimating an appropriate royalty rate, which is typically expressed as a percentage of revenue. Estimating an appropriate royalty rate includes reviewing evidence
from comparable licensing agreements and considering qualitative factors affecting the trade name. Given the subjectivity involved in selecting which BEV approach to use and in determining the input variables for use in our analyses, it is possible
that a different valuation model and the selection of different input variables could produce a materially different estimate of fair value of our trade name. We review the reasonableness of the carrying amount of our trade name on an annual basis
in conjunction with our goodwill impairment assessment. As of December 31, 2006, no impairment of our trade name existed. We cannot provide assurance that future trade name impairment testing will not result in impairment charges in subsequent
periods.

We amortize our identifiable intangible stock listing rights over their estimated useful lives in accordance with SFAS
No. 142, and test for potential impairment whenever events or changes in circumstances suggest that an asset or asset groups carrying value may not be fully recoverable in accordance with SFAS No. 144. An impairment loss, calculated
as the difference between the estimated fair value and the carrying value of an asset or asset group, is recognized if the sum of the estimated undiscounted cash flows relating to the asset or asset group is less than the corresponding carrying
value. As a result of our testing and analysis for the year ended December 31, 2006, with the assistance of an independent business valuation firm, we determined that there was no impairment of our stock listing rights under SFAS No. 144.
We cannot provide assurance that future stock listing rights impairment testing will not result in impairment charges in subsequent periods, particularly until the effects of the NYSEs HYBRID model can be more adequately assessed.

A prolonged period of weakness in equity markets and the trading of securities on the NYSE and AMEX could adversely impact our businesses and impair
the value of our goodwill and/or identifiable intangible assets. In addition, certain events could indicate a potential impairment of our identifiable intangible assets, including changes in market structure that could adversely affect our
specialist businesses; an adverse action or assessment by a regulator; or prolonged systemic failure of our self-developed specialist trading system.

Non-Marketable Securities

The use of fair value to measure certain non-marketable investments is a
critical accounting estimate. Investments in non-marketable securities consist of investments in equity securities of private companies, limited liability company interests and limited partnership interests, which do not have readily available price
quotations. Certain investments in non-marketable securities are initially carried at cost, as an approximation of fair value. Adjustments

---

to carrying value are made if there are third-party transactions evidencing a change in value. For certain other investments in non-marketable securities, we
adjust their carrying value by applying the equity method of accounting, and for our investment in a limited partnership interest, we adjust its carrying value by recognizing our share of the partnerships quarterly results of operations. In
addition, if and when available, management considers other relevant factors relating to non-marketable investments in estimating their fair value, such as the financial performance of the entity, its cash flow forecasts, trends within that
entitys industry and any specific rights associated with our investmentsuch as conversion featuresamong others.

We
account for our investment in the NYX stock at the estimated fair value of such restricted shares pursuant to the American Institute of Certified Public Accountants (AICPA) Audit and Accounting GuideBrokers and Dealers in
Securities.

Given managements judgment involved in valuing certain of our non-marketable securities, it is possible, as of a
given point in time, that a third-party could reach a different conclusion of fair value utilizing the same variables as we have in our analysis.

Non-marketable investments are tested for potential impairment whenever events or changes in circumstances suggest that an assets carrying value may be impaired.

Other-Than-Temporary Impairment of Exchange Memberships

The determination of the fair value of our exchange memberships is a critical accounting estimate. Exchange memberships owned by us are originally carried at cost, pursuant to the AICPA Audit and Accounting
GuideBrokers and Dealers in Securities. Adjustments to carrying value are made if we deem that an other-than-temporary decline in value, as defined in Emerging Issues Task Force (EITF) Issue No. 03-1, The
Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments,and in Section M of Topic 5 of the SEC staff accounting bulletin series (SAB No. 59), has occurred. In determining whether the value of our
owned exchange memberships is impaired (i.e., fair market value is below cost) and whether such impairment is temporary or other-than-temporary, we consider many factors, including, but not limited to, information regarding recent sale and
lease prices of exchange memberships, historical trends of sale and lease prices of memberships on a particular exchange and their duration, the current condition of the particular exchanges market structure, legal and regulatory developments
affecting the particular exchanges market structure and earnings capability, trends in new listings on the particular exchange, general global and national economic factors and our knowledge and judgment of the specialist and execution and
clearing industries and the securities market as a whole. As a result of our analysis of the above-mentioned factors for the year ended December 31, 2006, we believe the carrying values of our owned exchange memberships were not impaired.

We cannot provide assurance that the consistent application of this accounting policy to future reporting periods will not result in
further adjustments to the carrying value of any of our remaining exchange memberships following the consummation of the NYSE merger with Archipelago. This accounting policy, however, will no longer be applied in future periods to our NYSE
specialist operations because our NYSE memberships were surrendered in connection with the NYSE/Archipelago merger and our NYSE specialist operations and clearing operations will be conducted through trading licenses.

Use of Estimates

The use of generally accepted accounting principles requires management to make certain estimates. In addition to the estimates we make in connection with fair value measurements and the accounting for goodwill and
identifiable intangible assets, the use of estimates is also important in determining provisions for potential losses that may arise from litigation, regulatory proceedings and tax audits.

We estimate and provide for potential losses that may arise out of litigation, regulatory proceedings and tax audits to the extent that such losses are
probable and can be estimated, in accordance with SFAS No. 5, Accounting for Contingencies. Significant judgment is required in making these estimates and our final liabilities may ultimately be materially different. Our total
liability in respect of litigation and regulatory proceedings is determined on a case-by-case basis and represents an estimate of probable losses after considering, among other factors, the progress of each case or proceeding, our experience and the
experience of others in similar cases or proceedings, and the opinions and views of legal counsel. Given the inherent difficulty of predicting the outcome of our litigation and regulatory matters, particularly in cases or proceedings in which
substantial or indeterminate damages or fines are sought, we cannot estimate losses or ranges of losses for cases or proceedings where there is only a reasonable possibility that a loss may be incurred. See Legal Proceedings in Part I,
Item 3 of this Annual Report on Form 10-K for information on our judicial, regulatory and arbitration proceedings.

Execution and Clearing Risk

Our Execution and Clearing segment, through the normal course of business, enters into various securities transactions as agent. The
execution, settlement and financing of these transactions can result in unrecorded market risk and concentration of credit risk. Our execution and clearing activities involve settlement and financing of various customer securities transactions on a
cash or margin basis. These activities may expose us to risk in the event the customer or other broker is unable to fulfill its contractual obligations and we have to purchase or sell securities at a loss. For margin transactions, we may be exposed
to significant market risk in the event margin requirements are not sufficient to fully cover losses that customers may incur in their accounts.

Restructuring Transactions

In the fourth quarter of 2006 and January 2007, we implemented a restructuring plan which has
resulted in a significant headcount reduction and future reduction in compensation costs. Due primarily to the automation of securities markets such as the NYSEs HYBRID market, we reduced our headcount by 126 positions because we need fewer
people to execute trades on the floors of the exchanges on which we conduct business. As a result of this restructuring, we incurred additional compensation expense of approximately $3.7 million in connection with severance and supplemental
unemployment compensation. We expect our compensation expense and related benefits to decline by up to $14.1 million in 2007 as a result of this restructuring.

As of January 3, 2007, we converted our LaBranche Financial Services, Inc. (LFSI)
subsidiary into a limited liability company by way of a merger of LFSI with and into a newly formed limited liability company, which succeeded to all the rights, obligations and liabilities of LFSI. Subsequently, on January 17, 2007, the new
entity changed its name to LaBranche Financial Services, LLC. LaBranche & Co Inc. is the sole owner of LaBranche Financial Services, LLC, which is referred to in this annual report as LFS.

Completed Senior Note Repurchase

On August 2, 2004, we sold our investment in Lava Trading Inc. (Lava) as part of
the acquisition of Lava by Citigroup Financial Products, Inc. Upon the closing of the Lava acquisition, which constituted an asset sale under the terms of the Indenture, we received $39.0 million in cash. Under the Lava acquisition
agreement, additional consideration of approximately $9.6 million was being held in escrow to secure our indemnification obligations as a stockholder of Lava. The full amount of this escrow was released to us on October 31, 2005. An additional
$640,960 was received by us on or before October 31, 2005 in connection with the settlement by Lava of tax and insurance claims. Under the terms of the indenture governing our outstanding 9.5% Senior Notes due 2009 and our outstanding 11.0%
Senior Notes due 2012 (collectively, the outstanding senior notes), by the 361stday following the
receipt of these proceeds, we were required to offer to purchase outstanding senior notes in an aggregate principal amount equal to the after-tax amount of these proceeds to the extent we had not used any portion of such net cash proceeds to repay
any of our secured indebtedness or any indebtedness of our subsidiaries or to acquire replacement assets. Therefore, on October 24, 2006, we commenced an offer to purchase outstanding senior notes in the aggregate principal amount
of up to $6.6 million. This excess proceeds offer expired on November 22, 2006, with $26,000 principal amount of outstanding senior notes having been tendered. Following the closing of this transaction and the closings of other previous
offers to repurchase with immaterial tenders of senior notes, approximately $199.8 million aggregate principal amount of our Senior Notes due 2009 remained outstanding and approximately $260.0 million aggregate principal amount of our Senior Notes
due 2012 remained outstanding.

Revenues from our Specialist and Market-Making segment consist primarily of net gain earned from
principal transactions in securities for which we act as specialist and interest income. Net gain on principal transactions represents trading gains net of trading losses and SEC transaction fees, where applicable, and are earned by us when we act
as principal buying and selling our specialist stocks, rights, options, ETFs and futures. Also included in net gain on principal transactions are net gains and losses resulting from our market-making activities in ETFs, options and futures, the net
gains and losses resulting from trading of foreign currencies, futures and equities underlying the rights, ETFs and options for which we act as specialist, and accrued dividends receivable or payable on our equity positions. These revenues are
primarily affected by changes in share volume traded and fluctuations in prices of stocks, rights, options, ETFs and futures in which we are the specialist or in which we make a market.

Commissions revenue generated by our Specialist and Market-Making segment consists primarily of fees earned when our specialists act as agents by
executing limit orders on behalf of brokers, professional traders and broker dealers after a specified period of time; we do not earn commissions when we match market orders or when we act as a market-maker. Beginning December 2006 the NYSE
implemented a program of revenue sharing under which the NYSE will distribute a fixed rebate income support payment in the amount of approximately $53.0 million among the NYSE specialist firms for a six month transition period commencing
December 1, 2006. LaBranche & Co. LLC will receive approximately $2.04 million per month through May 2007 under this program. Commencing June 1, 2007, the NYSE revenue sharing program will be based on specialist firm performance.
There will be a base rebate on every trade a specialist enters on the NYSE in the amount of $0.000275 per share traded. Specialist firms will receive an additional rebate each month relating to their absolute market share in each of their specialist
stocks if that market share exceeds 35%. The specialist may be entitled to an additional rebate of between $0.00014 to $0.00016 per share for certain trades that exceed to-be-determined market share thresholds.

Interest revenue generated by our Specialist and Market-Making segment consists primarily of interest earned in securities lending transactions and
inventory financing in connection with our trading in options, futures and ETFs.

Revenues, net of interest expense, at our Specialist and
Market-Making segment is calculated after netting revenues by the interest expense related to those operations and the interest expense related to our public debt. The interest expense related to our Specialist and Market-Making segment is primarily
the result of inventory financing costs relating to positions taken in connection with our options, futures and ETFs specialist and market-making operations and interest on subordinated indebtedness that has been approved by the NYSE for inclusion
in the net capital of our LaBranche & Co. LLC subsidiary.

Key Metrics of our Specialist and Market-Making ActivitiesWhen assessing the

as follows:

Generally, an increase in the average daily share volume on the NYSE, an increase in volatility
(as measured by the average closing price of the CBOEs Volatility Index®, or the VIX), an increase in the dollar value and share volume of our principal shares or a decrease in program trading enables us to increase our level of principal participation and thus our ability to
realize net gain on principal transactions. While we monitor these metrics each period, they are not the sole indicators or factors in any given period that determine our level of revenues, profitability or overall performance. Other factors, such
as extreme price movements, unanticipated company news and events and other uncertainties may influence our financial performance either positively or negatively.

Year Ended December 31, 2006 Compared to Year Ended December 31, 2005

The decline in net gain on principal
transactions in our Specialist and Market-Making segment was attributable primarily to our cash equity specialist operations. The decrease was due to a decline in principal shares traded, as well as market volatility, as measured by the average
closing price of the VIX, which was unchanged year over year. Other factors that reduced our opportunity to participate was the continuing rise in program trading as a percentage of NYSE average daily share volume and decreases in NYSE average daily
share volume and dollar value of principal shares traded of stocks for which we are the equity specialist.

The increase in stock borrow
interest revenue generated by our Specialist and Market-Making segment consists primarily of interest earned in securities lending transactions and inventory financing in connection with our trading in options, futures and ETFs.

---

Other interest revenues increased due to the higher average interest rate yields earned on our investment
of excess cash.

Interest expense in our Specialist and Market-Making segment increased primarily as a result of increased inventory
financing costs relating to the growth and expansion of trading activity in our options, futures and ETFs specialist and market-making operations. Inventory financing costs increased from $36.6 million in 2005 to $186.7 million in 2006. While
interest expense increased to 30.4% of total segment revenues in 2006 from 13.2% in 2005, stock borrow interest income increased to 25.6% of total segment revenues in 2006 from 11.7% for 2005. Both stock borrow rebate and margin interest expense
should be considered as components in the overall computation of net trading revenue in the Specialist and Market-Making segment.

Our
Specialist and Market-Making segment realized a $120.1 million gain from the exchange of 36 NYSE memberships in the NYSE/Archipelago merger (another three memberships were held by our Execution and Clearing segment). We valued the 2.9 million
shares of NYX stock received in exchange for those 36 NYSE memberships at fair value, which was deemed to be the value of the shares on the first day of trading of NYX stock, or $67.00 per share, minus a 10% valuation allowance due to the
restrictions on transfer applicable to the shares. Since the consummation of the NYSE/Archipelago merger, we account for the investment in the NYX stock held by our Specialist and Market-Making segment at market value minus the valuation discount
attributable to the transfer restrictions (at December 31, 2006, the discount was 7%). At December 31, 2006, the NYSE closing market price for the NYX stock was $97.20 per share as compared to $67.00 per share at the date of the
NYSE/Archipelago merger. Thus, the aggregate gain, both realized and unrealized, in our Specialist and Market-Making segment with respect to the NYSE/Archipelago merger for 2006 was $220.3 million, including the dividend of $13.3 million we received
in connection with our NYSE memberships prior to the NYSE/Archipelago merger.

Operating Expenses below.

Year Ended December 31, 2005 Compared to Year Ended December 31, 2004

The increase in net gain on principal transactions is attributable primarily to our options, futures and ETFs specialist operations, with respect to which
trading revenue increased by approximately 82% from 2004 to 2005. This revenue growth was the result of an increase in the number of products traded, market-maker professionals and exchanges on which we trade our derivative products. This was offset
by a continued decrease in our cash equity specialist operations, in which trading revenue decreased by approximately 10% from 2004 to 2005. This decrease was at a lower rate than in 2004, but was similarly due to a decline in principal shares
traded as well as the continued decline in market volatility, as measured by the average closing price of the VIX. Another factor that reduced the opportunity for our cash equity specialists to participate was the continuing rise in program trading
as a percentage of NYSE average daily share volume. Program trading involves reducing large share orders into many smaller orders, resulting in the orders being matched electronically. These factors offset the benefit from the increases in NYSE
average daily share volume and share volume and dollar value traded for equity securities in which we are the specialist. We believe that market volatility declined as the level of mutual funds participation in the market declined.

Interest revenue earned by our Specialist and Market-Making segment was higher primarily due to an
increase in securities lending transactions, resulting from increased trading activity in our options, futures and ETFs specialist and market-making operations.

Other revenue earned by our Specialist and Market-Making segment was lower primarily due to decreased proprietary trading gains.

Interest expense in our Specialist and Market-Making segment increased primarily as a result of increased inventory financing costs relating to the growth and expansion of trading activity in our options, futures and
ETFs specialist and market-making operations. Inventory financing costs increased from $8.4 million in 2004 to $36.6 million in 2005. While interest expense increased to 13.2% of total segment revenues in 2005 from 4.0% in 2004, stock borrow
interest income increased to 11.7% of total segment revenues in 2005 from 1.6% for 2004. Both stock borrow rebate and margin interest expense should be considered as components in the overall computation of net trading revenue in the Specialist and
Market-Making segment.

Revenues, net of interest expense, at our Execution and Clearing segment is calculated after netting
revenues by the interest expense incurred in those operations, which consists of customers free credit balances, stock loan interest and bank loans.

Year Ended December 31, 2006 Compared to Year Ended December 31, 2005

Commission revenue from our Execution and
Clearing segment decreased as a result of a continued decline in direct-access floor broker order flow and reduced trade volume from execution and clearing customers. Interest income increased as a result of additional amounts invested in T-bills,
an increase in stock borrow interest income and a general increase in interest rates. Other revenue from our Execution and Clearing Segment remained relatively flat.

Our Execution and Clearing segment realized a $10.0 million gain from the exchange of three NYSE memberships in the NYSE/Archipelago merger (36 memberships were held by our Specialist and Market-Making segment). We
valued the 0.2 million shares of NYX stock received in exchange for those three NYSE memberships at fair value, which was deemed to be the value of the shares on the first day of trading of NYX stock, or $67.00 per share, minus a 10% valuation
allowance due to the restrictions on transfer applicable to the shares. Since the consummation of the NYSE/Archipelago merger, we account for our investment in the NYX stock held by our Execution and Clearing segment at market value minus the
valuation discount attributable to the transfer restrictions (at December 31, 2006, the discount was 7%). At December 31, 2006, the NYSE closing market price for the NYX stock was $97.20 per share as compared to $67.00 per share at the
date of the NYSE/Archipelago merger. Thus, our aggregate gain, both realized and unrealized, in our Execution and Clearing segment with respect to the NYSE/Archipelago merger for 2006 was $18.3 million, including the dividend of $1.1 million we
received in connection with our NYSE memberships prior to the NYSE/Archipelago merger.

Interest expense at our Execution and Clearing
segment remained relatively flat.

Year Ended December 31, 2005 Compared to Year Ended December 31, 2004

Commission revenue from our Execution and Clearing segment decreased as a result of a decline in direct-access floor broker order flow and reduced trade volume from clearance customers. This decline was partially
offset by an increase in revenues from our IEG group as a result of general growth and expansion of its customer base. Interest income increased as a result of additional amounts invested in T-bills and an increase in interest rates. In addition,
stock borrow income increased. Other revenue from our Execution and Clearing Segment remained relatively flat.

The portion of our revenues that is not generated from our two principal business segments
consists primarily of unrealized gains or losses on our non-marketable investments and interest income from short-term investments of our excess cash.

Revenues, net of interest expense, at our Other segment is calculated after netting revenues by the interest expense related to our public debt and interest accrued on reserves.

Year Ended December 31, 2006 Compared to Year Ended December 31, 2005

Interest revenue increased primarily due to higher rates on our short-term investments. Other revenues decreased primarily due to the fact that we did not realize a gain in 2006 from the final installment (due to the
release of an escrow) in October 2005 of $9.6 million from the sale of our investment in Lava.

Interest expense in our Other segment,
increased to $52.9 million in 2006 from $51.7 in 2006, primarily due an increase in interest accrued on contingent tax reserves.

For a
discussion of operating expenses see Our Operating Expenses below.

Year Ended December 31, 2005 Compared to Year Ended
December 31, 2004

Interest revenue increased primarily due to higher rates on our short-term investments. Other revenues decreased
primarily as a result of the smaller realized gain from the final installment (due to the release of an escrow) in October 2005 of $9.6 million from the sale of our investment in Lava versus the $24.9 million realized gain in 2004 in connection with
the disposition of our investment in Lava.

Interest expense in our Other segment decreased to $51.7 million in 2005 from $53.8 million in
2004, primarily due to long-term debt repayments on maturity.

Our Specialist and Market-Making segments employee compensation and related benefits expense
consists of salaries, wages and incentive compensation paid to our traders and related support staff. The employee compensation and benefits expense related to our Execution and Clearing segment consists of salaries, wages and incentive compensation
paid to our execution and clearing professionals, as well as compensation based on commissions earned by various trading professionals. Incentive compensation may include cash compensation and stock-based compensation paid or granted to managing
directors, trading professionals and other employees based on our results, their contributions to our business and other factors.

Exchange, clearing and brokerage fees expense at our Specialist and Market-Making segment consists primarily of fees paid by us to the NYSE, AMEX, other exchanges, the Depository Trust Clearing Corporation (DTCC) and to third
party execution and clearing companies. The fees paid by us to these entities are primarily based on the volume of transactions executed by us as principal and as agent, a fee based on exchange seat/trading license use, an allocation fee requiring
specialist firms to share the cost of newly allocated listings, technology fees, a flat annual fee and execution and clearing fees. These fees are expected to decline in 2007 based on the new fee structure at the NYSE. Our Execution and Clearing
segments exchange, clearing and brokerage fees expense consists of floor brokerage fees paid to direct-access floor brokers and fees paid to various exchanges.

Other operating expenses primarily are comprised of occupancy costs, such as office space and equipment leases and utilities, communications costs, professional, legal and consulting fees and restructuring costs.

Year Ended December 31, 2006 Compared to Year Ended December 31, 2005

While consolidated employee compensation and related benefits expense declined in 2006 compared to 2005, there were material changes within the components
of employee compensation and benefits expense in each of our business segments year over year. The main cause of these changes was the decrease in incentive compensation, salaries and related benefits in connection

---

with our specialist and market-making operations resulting from decreased profitability and declines in the number of personnel. The satisfaction and payment
of a retention bonus plan liability, and the December 2005 termination of a deferred compensation plan, both related to a prior acquisition, contributed to the decline in employee compensation in 2006. Salaries and incentive compensation in our
Execution and Clearing segment declined due to a decline in trading and support personnel. Employee compensation and related benefits decreased to 20.4% of revenues, net of interest expense, in 2006 from 41.3% in 2005.

Exchange, clearing and brokerage fees increased primarily due to increased trading activity in our options, futures and ETFs specialist and market-making
operations. Partially offsetting the increase was a decrease in exchange, clearing and brokerage fees at our Execution and Clearing segment related to lower revenues from direct-access floor brokers. Exchange, clearing and brokerage fees declined to
10.6% of revenues, net of interest expense, in 2006 from 16.2% in 2005.

Lease of exchange memberships increased as a result of the number
of trading licenses we obtained since we no longer own 39 NYSE memberships following the NYSE/Archipelago merger. Lease of exchange memberships expense decreased to 1.1% of revenues, net of interest expense, in 2006 from 1.6% for the same period in
2005.

Other operating expenses increased slightly in 2006 compared to 2005 due to an increase in occupancy expense in connection with our
move to new space in New York and the overlap of rent in the office space we rented prior to our move and in connection with the reduction of our headcount by 126 positions due to automation in the NYSEs HYBRID market. As a result of this
restructuring, we incurred additional compensation expense and related benefits of $3.7 million in connection with severance and supplemental unemployment compensation paid.

SFAS No. 142, Goodwill and Other Intangible Assets (SFAS No. 142) requires entities to test goodwill for possible
impairment on an annual basis, or more frequently, if certain events and circumstances exist. We tested our goodwill for impairment at December 31, 2006, per the annual testing requirement, and noted no further impairment of this asset at
that date. For a more complete description of our methodology in evaluating the reasonableness of the carrying value of our goodwill, please see Critical Accounting Estimates.

Our expense for income taxes increased in 2006 to $100.2 million, versus a tax expense of $13.6 million in 2005. Our effective tax rate rose to 42.3% in
2006 from 26.6% in 2005. In 2006, the effective tax rate was lower than the statutory rate due to a tax benefit that resulted from a permanent difference related to dividends. In 2005, the effective rate was lower than the statutory rate due to
significant tax benefits recognized by a tax rate change applied to our net deferred tax liability.

While consolidated employee compensation and related benefits expense increased

---

slightly in 2005 as compared to 2004, there were material changes within the components of employee compensation and benefits expense in each of our business
segments year over year. The main cause of these changes was the increase in incentive compensation, salaries and related benefits in connection with our options, futures and ETFs specialist and market-making operations resulting from increased
trading and support personnel. These increases were partially offset by decreases in compensation related to our cash equity specialist activities due to a reduction in personnel. The satisfaction and payment of a retention bonus plan liability, and
the December 2005 termination of a deferred compensation plan, both related to a prior acquisition, also partially offset the increase in employee compensation. Salaries and incentive compensation at our Execution and Clearing segment declined due
to a decrease in trading and support personnel. Employee compensation and related benefits increased to 41.3% of revenues, net of interest expense, in 2005 from 38.9% in 2004.

Exchange, clearing and brokerage fees increased primarily due to increased trading activity in our options, futures and ETFs specialist and market-making
operations. Partially offsetting the increase was a decrease in exchange, clearing and brokerage fees at our Execution and Clearing segment related to lower revenues from direct-access floor brokers. Exchange, clearing and brokerage fees increased
to 16.2% of revenues, net of interest expense, in 2005 from 15.3% in 2004.

Lease of exchange memberships decreased substantially as a
result of the decline in the average annual lease cost of an NYSE membership and a decrease in the number of our leased NYSE memberships. Our average annual lease cost of an NYSE membership in 2005 was approximately $70,000, as compared to
approximately $235,000 in 2004. Additionally, we leased on average approximately 11 fewer NYSE seats in 2005 than we did in 2004. Lease of exchange memberships expense decreased to 1.5% of revenues, net of interest expense, in 2005 from 6.1% for the
same period in 2004.

Other operating expenses decreased in 2005 as compared to 2004 primarily due to an decrease in legal, audit and other
professional fees incurred primarily in connection with Sarbanes-Oxley Act compliance, as well as fees charged on a committed revolving credit facility established in the first quarter of 2004, which was terminated upon the completion of the
refinancing of our indebtedness on May 18, 2004.

SFAS No. 142, Goodwill and Other Intangible Assets (SFAS
No. 142) requires entities to test goodwill for possible impairment on an annual basis, or more frequently, if certain events and circumstances exist. We tested our goodwill for impairment at December 31, 2005, per the annual
testing requirement, and noted no further impairment of this asset at that date. In September 2004, we recorded a goodwill impairment charge of $37.6 million, all of which was attributable to our Specialist and Market-Making segment. The impairment
charge, which represented the excess of the carrying value of our Specialist and Market-Making segments goodwill over its implied fair value, was necessary to properly reflect the carrying value of our goodwill at September 30, 2004. We
updated our third quarter 2004 goodwill valuation results at December 31, 2004, per the annual testing requirement, and noted no further impairment of this asset at that date. For a more complete description of our methodology in
evaluating the reasonableness of the carrying value of our goodwill, please see Critical Accounting Estimates.

We did not record an exchange-membership impairment in 2005. In 2004, however, we recorded an $18.3
million other-than-temporary impairment charge related to our NYSE exchange memberships. Of this total, $16.3 million was attributable to our Specialist and Market-Making segment and $2.0 million was attributable to our Execution and Clearing
segment.

Our 2004 operating expenses included a $49.0 million charge in connection with the repurchase of a substantial portion of our
then-outstanding senior notes and senior subordinated notes. This charge was attributable to a consent payment, which was offered to debt holders who tendered their 2004 Notes and 2007 Notes by April 19, 2004, and a premium for tendering the
2004 Notes and 2007 Notes for purchase prior to their maturity. No such expenses were incurred in 2005.

Our expense for income taxes
increased in 2005 to $13.6 million, versus a tax benefit of $12.0 million in 2004. Our effective tax rate rose to 26.6% in 2005 from 21.8% in 2004. The 2004 effective rate was lower than the statutory rate mainly due to the reduction of
non-deductible goodwill impairment limiting the tax benefit from the loss. In 2005, the effective rate was lower than the statutory rate due to significant tax benefits recognized by a tax rate change applied to our net deferred tax liability.

Liquidity and Capital Resources

As of
December 31, 2006, we had $5,374.9 million in assets, of which $599.8 million consisted of cash and short-term investments, primarily in government obligations maturing within three months, cash and securities segregated under federal
regulations and overnight repurchase agreements. To date, we have financed our operations primarily with retained earnings from operations and proceeds from our debt and equity offerings. Due to the nature of the securities business and our role as
a specialist, market-maker and execution agent, the amount of our cash and short-term investments, as well as operating cash flow, may vary considerably due to a number of factors, including the dollar value of our positions as principal, whether we
are net buyers or sellers of securities, the dollar volume of executions by our customers and clearing house requirements, among others. Certain regulatory requirements constrain the use of a portion of our liquid assets for financing, investing or
operating activities. Similarly, the nature of our business lines, the capital necessary to maintain current operations and our current funding needs subject our cash and cash equivalents to different requirements and uses.

As of December 31, 2006, the scheduled maturities of our contractual obligations, without taking into account any available roll-over provisions,
were as follows:

The above table includes indebtedness with primarily long-term maturities, the interest and principal
payments of which have a significant effect on the cash available to finance our current and future operations. As of December 31, 2006, our most significant long-term indebtedness was the $199.8 million aggregate principal amount of our
outstanding senior notes that mature in May 2009, and the $260.0 million aggregate principal amount of our outstanding senior notes that mature in May 2012.

At December 31, 2006, our net cash capital position was $149.1 million. Fluctuations in net cash capital are common and are a function of variability in our total assets, balance sheet composition and total
capital. We attempt to maintain cash capital sources in excess of our aggregate longer-term funding requirements (i.e., positive net cash capital). Over the previous 12 months, our net cash capital has averaged above $100 million.

Cash Capital Available is mainly comprised of stockholders equity, long term
debt, subordinated debt and other liabilities of our parent holding company which, in the aggregate, constitute the currency used to purchase our assets and provide our working capital. This amount will principally be affected as debt matures or is
refinanced and as earnings are retained or paid as dividends. Cash Capital Required mainly consists of the assets used in our businesses. Regulatory capital is defined as capital required by the SEC and applicable exchanges to be
maintained by broker-dealers. It is principally comprised of cash, net equities, other investments and net receivables from other broker-dealers. Working capital constitutes liquid assets provided to our subsidiaries in excess of the required
regulatory capital. Illiquid assets and long term investments are mainly comprised of exchange memberships, intangible assets, such as goodwill, tradename and stock listing rights, deposits, deferred taxes and non-marketable investments. Net
Cash Capital is considered to be the excess of Cash Capital Available over Cash Capital Required, or free cash, which we can utilize to fund our business needs.

We also monitor alternative funding measures in addition to our available net cash. The alternative funding measures are significant transactions and
actions we could take in a short-

term time frame to generate cash to meet debt maturities or other business needs. More precisely, as of December 31, 2006, we have identified the
following alternative funding measures to support future debt maturity requirements:



| |  |  | Liquidation of net invested capital at certain subsidiaries.
| | - |  | ------------------------------------------------------------



| |  |  | Reduction of excess capital at LaBranche & Co. LLC to only required net liquid assets (excess NLA dividend)
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | Further reduction of NLA requirements by the NYSE and SEC.
| | - |  | ----------------------------------------------------------



| |  |  | Our restricted NYX shares, as previously discussed, can be either sold or held as good capital as their restrictions are removed. If the shares are held as good
capital, no tax charge is applied and cash can be freed from its current use as NLA capital.

In addition to the alternative funding measures above, we monitor the maturity profile of our unsecured debt to minimize refinancing risk and we maintain relationships with debt investors and bank creditors. Strong relationships with a
diverse base of creditors and debt investors are critical to our liquidity. We also maintain available sources of short-term funding that exceed actual utilization, thus allowing us to accommodate changes in investor appetite and credit capacity for
our debt obligations.

With respect to the management of refinancing risk, the maturity profile of our long-term debt portfolio is
monitored on an ongoing basis and structured within the context of two significant debt tranches with a significant spread of years between maturities (mid-term and long-term). Thus, we have strategically negotiated debt terms maturing in 2009 and
2012 for the significant debt tranches. In addition, the debt tranches have call provisions which allow pre-maturity retirements as early as 2007. The debt tranches have available maturities and calls over the six year period 2007 through 2012 to
allow us maximum flexibility in satisfying the debt maturities with payments and/or sufficient time to refinance the long-term debt as required. The following chart profiles our long-term debt maturity schedule as of December 31, 2006.

Our outstanding senior notes were issued pursuant to an indenture which includes certain covenants that, among
other things, limit our ability to make certain investments, engage in transactions with stockholders and affiliates, create liens on our assets and sell assets or engage in mergers and consolidations, except in accordance with certain specified
conditions. In addition, our ability to make so-called restricted payments, such as incurring additional indebtedness (other than certain permitted indebtedness), paying dividends, redeeming stock or repurchasing subordinated
indebtedness prior to maturity, is limited if our consolidated fixed charge coverage ratio is at or below a threshold of 2.00:1. The consolidated fixed charge coverage ratio reflects a comparison between (1) our consolidated
earnings before interest, taxes, depreciation and amortization expenses, or EBITDA, and (2) the sum of our consolidated interest expense and a tax-effected multiple of any dividend payments with respect to our preferred stock. As of
December 31, 2006, our consolidated fixed charge coverage ratio, as defined, was 1.60:1, which means we currently cannot make any restricted payments, other than repurchasing our outstanding senior notes and any restricted
payments up to an aggregate of $15.0 million over the life of the indenture. Even though our fixed charge coverage ratio is below 2.00:1, we are still in compliance with all our covenants under the indenture.

In addition, under the indenture governing our outstanding senior notes, if, at any time, our cumulative restricted payments since
May 18, 2004 generally are greater than (i) the sum of (A) 50.0% of our cumulative consolidated net income, as defined in the indenture, since July 1, 2004 (or, if such calculation is a loss, minus 100.0% of such loss) and
(B) 100.0% of the net cash proceeds received from any issuance or sale of our capital stock since July 1, 2004, plus (ii) $15.0 million, we will not be entitled to make a restricted payment at such time. As of
December 31, 2006, our cumulative consolidated net income since July 1, 2004 was $176.4

million, and we had received approximately $1.4 million upon the exercise of options since July 1, 2004. As explained above, however, our fixed
charge coverage ratio currently is below 2.00:1 and accordingly, we are unable to make restricted payments greater than the $15.0 million basket described above. While we have not made any restricted payments since May 18,
2004, we cannot be sure if, when or to what extent this covenant will prevent or limit us from making restricted payments in the future.

The indenture governing our outstanding senior notes permits us to redeem some or all of the senior notes due 2009 on or after May 15, 2007 and some or all of the senior notes due 2012 on or after May 15, 2008 at varying
redemption prices, depending on the date of redemption. In addition, we have the option to redeem up to 33.0% of the aggregate principal amount of the senior notes due 2009 at a redemption price of 109.5% and up to 33.0% of the aggregate principal
amount of the senior notes due 2012 at a redemption price of 111.0% using the proceeds of certain equity offerings which we may complete on or prior to May 15, 2007. Under the terms of the indenture, if we sell substantially all our assets or
experience specific kinds of changes in control, we will be required to offer to repurchase outstanding senior notes, on a pro rata basis, at a price in cash equal to 101.0% of their principal amount, plus accrued and unpaid interest, if any, to the
date of purchase. To the extent we repurchase any outstanding senior notes in connection with future corporate strategic initiatives, our fixed-term interest payments would be correspondingly reduced.

The remaining $13.6 million aggregate principal amount of senior subordinated notes due 2007 that we did not repurchase in connection with our May 2004
debt refinancing will continue to accrue interest at a rate of 12.0% per annum until they mature on March 2, 2007. We intend on repaying the full amount of principal and interest on these notes at maturity.

As of December 31, 2006, the subordinated indebtedness of LaBranche & Co. LLC aggregated $9.4 million. This subordinated debt is comprised
of senior subordinated notes and junior subordinated notes, which mature on various dates between February 2007 and June 2008 and bear interest at annual rates ranging from 7.7% to 10.0%. The senior subordinated notes were originally issued in the
aggregate principal amount of $15.0 million, and, in accordance with their terms, $3.0 million in principal amount must be repaid on June 3 of each of 2004, 2005, 2006, 2007 and 2008. LaBranche & Co. LLC repaid $3.0 million in
accordance with these terms in each of June 2004, 2005 and 2006. LaBranche & Co. LLC may prepay, at a premium, all or any part of such senior subordinated notes at any time, provided that the amount prepaid is not less than 5.0% of the
aggregate principal amount of such senior subordinated notes then outstanding. Upon the occurrence of a change of control, LaBranche & Co. LLC may, but is not required to, make one irrevocable separate offer to each holder of the senior
subordinated notes to prepay all the senior subordinated notes then held by that holder. The occurrence of a change of control also constitutes an event of acceleration under the senior subordinated notes. Our outstanding junior subordinated notes
in the aggregate principal amount of $3.4 million, have automatic rollover provisions, which extend their maturity for an additional year, unless we provide at least seven months advance notice of our intention not to renew at maturity.
LaBranche & Co. LLC is entitled to prepaywith written consent from the NYSEthe junior subordinated notes without penalty under the terms of the agreements relating thereto.

As of December 31, 2006, our outstanding indebtedness included eight separate note obligations, each
in the principal amount of $1.0 million, which mature in August 2007 and bear interest at an annual rate of 9.0%.

On October 24, 2006, pursuant to the terms of the indenture governing the senior notes, we offered to purchase outstanding senior notes in the aggregate principal amount of up to $6.6 million. This offer expired
on November 22, 2006, with $26,000 principal amount of outstanding senior notes having been tendered. Following the closing of this transaction and the closings of other previous offers to repurchase with immaterial tenders of senior
notes, approximately $199.8 million aggregate principal amount of our senior notes due 2009 remained outstanding and approximately $260.0 million aggregate principal amount of our senior notes due 2012 remained outstanding. For a more detailed
description of this transaction, please see Completed Senior Note Repurchase.

As of December 31, 2005, we owned 39
NYSE memberships, with a combined value of $58.5 million, out of a total 1,366 NYSE memberships, representing a 2.9% ownership interest in the NYSE. Upon consummation of the NYSE merger with Archipelago on March 7, 2006, each NYSE membership
became entitled to receive in exchange for the NYSE membership $300,000 in cash, plus 80,177 shares of NYSE Group common stock. In addition, immediately prior to the consummation of the NYSE/Archipelago merger, the NYSE announced the declaration of
a permitted dividend payable with respect to each NYSE membership in the amount of approximately $70,570, which was equivalent to each memberships pro rata portion of the NYSEs excess cash, as defined in the
NYSE/Archipelago merger agreement. In the NYSE/Archipelago merger, in exchange for our 39 NYSE memberships, we received an

aggregate of $11.7 million in cash (not including the permitted dividend) and 3,126,903 shares of NYSE Group common stock. We received the permitted dividend
with respect to each of the 39 NYSE memberships on March 14, 2006, and we received the remaining merger consideration on March 21, 2006.

As a specialist and market-maker, we are required to maintain certain levels of capital and liquid assets as promulgated by various regulatory agencies which regulate our business. As part of our overall risk management procedures (for
further discussion, refer to Part I, Item 3. Quantitative and Qualitative Disclosures about Market Risk), we attempt to balance our responsibility as specialist, market-maker and broker-dealer with our overall capital resources.
These requirements restrict our ability to make use of cash and other liquid assets for corporate actions, such as repaying our debt, repurchasing stock or making acquisitions.

As a broker-dealer, LaBranche & Co. LLC is subject to regulatory requirements intended to
ensure the general financial soundness and liquidity of broker-dealers and requiring the maintenance of minimum levels of net capital, as defined in SEC Rule 15c3-1. LaBranche & Co. LLC is required to maintain minimum net capital, as
defined, equivalent to the greater of $100,000 or1/15of aggregate indebtedness, as defined. NYSE Rule 326(c) also prohibits a broker-dealer from repaying subordinated borrowings, paying cash dividends, making
loans to any parent, affiliates or employees, or otherwise entering into transactions which would result in a reduction of its total net capital to less than 150.0% of its required minimum capital. Moreover, broker-dealers are required to notify the
SEC prior to repaying subordinated borrowings, paying dividends and making loans to any parent, affiliates or employees, or otherwise entering into transactions which, if executed, would result in a reduction of 30.0% or more of their excess net
capital (net capital less minimum requirement). The SEC has the ability to prohibit or restrict such transactions if the result is deemed detrimental to the financial integrity of the broker-dealer. As of December 31, 2006, LaBranche &
Co. LLCs net capital, as defined, was $365.5 million, which exceeded the minimum requirements by $364.3 million.

The NYSE generally
requires its specialist firms to maintain a minimum dollar regulatory capital amount in order to establish that they can meet, with their own net liquid assets, their position requirement. Prior to September 1, 2006, LaBranche & Co.
LLCs and LSPS net liquid asset requirements were combined. The combined requirement was satisfied by LaBranche & Co. LLCs net liquid assets alone. Subsequent to September 1, 2006, each of LaBranche & Co. LLC
and LSPS is required to compute and meet its own requirement. As of December 31, 2006, LaBranche & Co. LLCs NYSE minimum required dollar amount of net liquid assets, as defined, was $323.3 million, and its actual net liquid
assets, as defined, were $360.9 million. LSPS net liquid assets requirement as of December 31, 2006 is discussed below. As of December 31, 2005, LaBranche & Co. LLCs and LSPS combined NYSE minimum required dollar
amount of net liquid assets, as defined was $447.0 million, and its actual net liquid assets, as defined, were $459.3 million. LaBranche & Co. LLC thus satisfied its net liquid asset requirement as of each of those dates.

On July 25, 2006, the SEC approved a reduction of the minimum dollar regulatory capital for a specialist in cash equities and increased the
requirement for a specialist in ETFs. This reduction is to be effected in four quarterly installments, the first two of which were on September 1, 2006 and December 1, 2006. After the first installment, LaBranche & Co. LLC paid to
us a dividend of $49 million, and after the second installment, LaBranche & Co. LLC



69



---

paid to us a dividend of $57 million. These dividend payments were mainly comprised of the NLA reduction payments but also included dividends for excess
regulatory capital. LaBranche & Co. LLCs aggregate required minimum NLA will be further reduced in additional installments on March 1, 2007 and June 1, 2007.

The AMEX generally requires its equity specialist firms to maintain a cash or liquid asset position equal to the greater of (a) $1.0 million or
(b) an amount sufficient to assume a position of sixty trading units of each security in which the equity specialist is registered. As of December 31, 2006 and December 31, 2005, LaBranche & Co. LLC satisfied the AMEX equity
specialist liquid asset requirements.

As a registered broker-dealer and member firm of the NYSE, LFS is also subject to SEC Rule 15c3-1,
as adopted and administered by the SEC and the NYSE. Under the alternative method permitted by this rule, the minimum required net capital is equal to the greater of $1.5 million or 2.0% of aggregate debit items, as defined. As of December 31,
2006 and December 31, 2005, LFS net capital, as defined, was $38.3 million and $19.7 million, respectively, which exceeded minimum requirements by $36.8 million and $18.2 million, respectively.

As a clearing broker-dealer, LFS also is subject to SEC Rule 15c3-3, as adopted and administered by the SEC. As of January 3, 2007, to comply with
its December 31, 2006 requirement, cash and U.S. Treasury Bills in the amount of $3.7 million were segregated in a special reserve account for the exclusive benefit of customers, thus exceeding actual requirements by $1.7 million. As of
January 4, 2006, to comply with its December 31, 2005 requirement, cash and U.S. Treasury Bills in the amount of $1.2 million were segregated in a special reserve account for the exclusive benefit of customers, exceeding actual
requirements by $1.2 million. In addition, the Proprietary Accounts of Introducing Brokers (PAIB) Calculation is computed in order for correspondent firms to classify their assets held by LFS as allowable assets in the
correspondents net capital calculation. As of January 3, 2007, to comply with LFS December 31, 2006 requirement, cash and U.S. Treasury Bills in the amount of $5.2 million were segregated in a special reserve account for the
exclusive benefit of PAIB customers, exceeding actual requirements by $1.0 million. As of January 4, 2006, to comply with LFSIs December 31, 2005 requirement, cash and U.S. Treasury Bills in the amount of $5.7 million were segregated
in a special reserve account for the exclusive benefit of customers, thus exceeding actual requirements by $2.0 million.

As a registered broker-dealer and AMEX member firm, LSP is subject to SEC Rule 15c3-1, as adopted
and administered by the SEC and the AMEX. LSP is required to maintain minimum net capital, as defined, equivalent to the greater of $100,000 or1/15of aggregate indebtedness, as defined. As of
December 31, 2006 and December 31, 2005, LSPs net capital, as defined, was $68.2 million and $56.8 million, respectively, which exceeded minimum requirements by $67.4 million and $55.7 million, respectively. LSPs aggregate
indebtedness to net capital ratio on those dates was .18 to 1 and .29 to 1, respectively.

LSPS, as a specialist and member of the NYSE, is subject to the provisions of SEC Rule 15c3-1, as adopted and administered by the SEC and NYSE. LSPS is required to maintain minimum net capital, as defined, equivalent to the greater of
$100,000 or1/15of aggregate indebtedness, as defined. As of December 31, 2006 and December 31, 2005, LSPS net capital,



70



---

as defined, was $20.2 million and $10.7 million, respectively, which exceeded the minimum requirements by $20.0 million and $10.6 million, respectively.
LSPS aggregate indebtedness to net capital ratio on those dates was .12 to 1 and .16 to 1, respectively. As of December 31, 2006, LSPS NYSE minimum required dollar amount of net liquid assets, as defined, was $13.5 million, and its
actual net liquid assets, as defined, were $19.8 million. Prior to September 1, 2006, LSPS was not required to perform a separate net liquid assets calculation because LaBranche & Co. LLCs actual net liquid assets exceeded the
combined net liquid assets requirement of LaBranche & Co. LLC and LSPS.

As
a registered broker-dealer and AMEX member firm, LSPD is subject to SEC Rule 15c3-1, as adopted and administered by the SEC and AMEX. LSPD is required to maintain minimum net capital, as defined, equivalent to the greater of $5,000 or1/15of aggregate indebtedness, as defined. As of December 31, 2006, LSPDs net capital, as defined, was $3.0 million, which exceeded its minimum requirements by $3.0 million.

Failure by any of our broker-dealer subsidiaries to maintain its required net capital and net liquid assets, where applicable, may subject it to
suspension or revocation of its SEC registration or its suspension or expulsion by the NYSE, the AMEX and/or any other exchange of which it is a member firm.

As evidenced by the foregoing requirements, our broker-dealer subsidiaries require a substantial amount of capital. In particular, LaBranche & Co. LLCs net liquid asset requirement of $323.3 million
limits our ability to utilize a substantial portion of our liquid assets for other corporate purposes. Although a portion of the combined net liquid asset requirement of $323.3 million is met by LaBranche & Co. LLCs securities
positions, pending trades and other assets associated with our equity specialist activities, a substantial portion of LaBranche & Co. LLCs cash and cash equivalents as of December 31, 2006 was used to meet its net liquid asset
requirement.

On March 7, 2007, trading restrictions with respect to 1,042,301 of our 3,126,903 shares of NYX common stock will lapse.
It is possible that, beginning on or after March 7, 2007, we may use at least a portion of such 1,042,301 shares of NYX stock to satisfy our net capital and net liquid assets requirements at LaBranche & Co. LLC, subject to required
haircuts. In the event we use those NYX shares to satisfy our requirements, additional cash that has been used to meet these requirements could be used for other corporate purposes, including repurchasing our outstanding senior notes.

As of December 31, 2006, we had a tax receivable of $5.4 million and a tax payable of $10.5 million with respect to our 2005 tax year. The 2006 tax
receivable of $5.4 million included a pending tax assessment of $2.6 million as of December 31, 2006.

Our Other
liabilities of $15.2 million reflected on the accompanying 2006 consolidated statement of financial condition are comprised of legal and tax contingencies pursuant to SFAS 5. Such contingencies are considered long term, as there is no present
obligation to pay such liabilities in the foreseeable future.

We currently anticipate that we will be able to meet our working capital, regulatory capital and capital
expenditure requirements through at least the next twelve months.

Credit Ratings

Our outstanding senior notes were originally sold in private sales to institutional investors on May 18, 2004, and substantially all these senior
notes were subsequently exchanged for substantially identical senior notes registered under the Securities Act of 1933, as amended, pursuant to the terms of our May 2004 debt refinancing. The senior subordinated notes that remain outstanding since
our May 2004 debt refinancing, in the aggregate principal amount of $13.6 million, are publicly held but are no longer rated. The following table sets forth the credit ratings on our registered outstanding senior notes as of December 31, 2006:



|                  |  |                          |  |                 
|----------------- |  | ------------------------ |  | ----------------
|                  |  | MoodysInvestors Service |  | Standard &Poors
|2009 Senior Notes |  | Ba2                      |  | B               
|                  |  |                         
|2012 Senior Notes |  | Ba2                      |  | B               

In August 2005, although Moodys Investor Services changed its credit rating of our
outstanding senior notes from Ba1 to Ba2, it improved its outlook to stable due to our high quality balance sheet and improved liquidity. In September 2005, Standard & Poors also improved its outlook on our outstanding senior notes to
stable, while affirming our B rating, due to our improved debt service and liquidity positions. There were no updates to these credit ratings by either Moodys or Standard & Poors in 2006.

Cash Flows

Our cash flows are related primarily to
our specialist trading activities, as well as to our financing activities related to the expansion of our business.

Year Ended
December 31, 2006Our cash and cash equivalents increased $130.1 million to $557.4 million at the end of 2006. The increase was primarily the result of the combined effects of $32.1 million of positive cash flow from earnings, a $104.0
million net decrease in working capital applied to broker/dealer receivables and payables and investments, a $44.0 million decrease in securities purchased under an agreement to resell offset by an aggregate $29.2 million decrease of net other
liabilities over other assets, a $17.7 million expenditure for capital assets and a $3.0 million repayment of subordinated debt.

Year
Ended December 31, 2005Our cash and cash equivalents decreased $17.1 million to $427.3 million at the end of 2005. The decrease was the result of the combined effects of a $7.3 million repayment of debt and minority interest
obligations, a $1.3 million expenditure for capital assets and a $14.6 million payment of a deferred compensation arrangement offset by $6.0 million of positive net operating activity cash flows.



72



---

Year Ended December 31, 2004Our cash and cash equivalents decreased $47.4 million to
$444.4 million at the end of 2004. The decrease was the result of $125.4 million used in our operating activities primarily for payment of the $63.5 million in restitution and fines in settlement of the prior years NYSE and SEC specialist
investigation and a $74.0 million increase in repurchase agreements. This decrease was partially offset by $79.0 million provided as a result of the refinancing of our indebtedness.



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

Due to regulatory requirements that prescribe communication barriers between our broker-dealer subsidiaries, we employ different compliance risk management procedures at each such subsidiary. These risk processes are set forth below:

Our Cash Equity Specialist Risk Management Process

Because our equity specialist activities on the NYSE and AMEX expose our capital to significant risks, managing these risks is a constant priority for us. Our central role in the HYBRID market helps us to manage risks
by incorporating up-to-date market information in the management of our inventory, subject to our specialist obligations. We have developed a risk management process at our LaBranche & Co. LLC subsidiary that is designed to balance our
ability to profit from our specialist activities with our exposure to potential losses and compliance risk. This risk management process includes participation by our corporate compliance committee, executive operating committee, floor management
committee, post managers, floor captains, specialists and chief risk officer. These parties roles are as follows:

Corporate
Compliance Committee. Our corporate compliance committee was established in February 2002 and consists of representatives from executive and senior management, compliance personnel, including our on-floor compliance officer, our general counsel,
our chief regulatory officer and several additional senior floor specialists, known as post managers. The role of the corporate compliance committee is to monitor and report to senior management on the statutory and regulatory compliance efforts of
our specialist business. The corporate compliance committee also advises the compliance department in establishing, reviewing and revising our policies and procedures governing LaBranche & Co. LLCs regulatory compliance structure.

Executive Operating Committee. Our executive operating committee is composed of two executive officers. This committee is
responsible for approving all risk management procedures and trading guidelines for our specialist stocks, after receiving recommendations from our floor management committee. In addition, our executive operating committee reviews all unusual
situations reported to it by our floor management committee.

Floor Management Committee. Our NYSE floor management committee is
composed of five post managers, two wheel managers, two floor managers, one SWAT team manager and one quality assurance manager. This committee is responsible for formulating and overseeing our overall risk management procedures and trading
guidelines for each of our specialist stocks. In determining these procedures and guidelines, the floor management committee considers the



73



---

recommendations of the floor captains. The post managers meet with their respective floor captains on a weekly basis to review and, if necessary, revise the
risk management procedures and trading guidelines for particular specialist stocks. The wheel managers ensure that the floor is adequately staffed at all times. In addition, post managers, wheel managers and floor captains are always available on
the trading floor to review and assist with any unusual trading situations reported by a floor captain, and the swat-team manager is available to assess and provide assistance on break-out, or intense, trading situations. Our floor management
committee reports to our executive operating committee about each of these trading situations as they occur. Our floor management committee also trains other specialists and trading assistants on a regular basis on new rules and/or interpretations
from the NYSE with respect to our specialist obligations and guidelines, with the assistance of our compliance department.

Floor
Captains. We employ eight floor captains who monitor the activities of our cash equity specialists throughout the trading day from various positions at our trading posts. The floor captains observe trades and constantly review trading activities
on a real-time basis. In addition, the floor captains are readily available to assist our specialists in determining when to deviate from procedures and guidelines in reacting to any unusual situations or market conditions. The floor captains report
these unusual situations and any deviations from these procedures and guidelines to their respective post managers. Floor captains meet with each specialist at least once a week to evaluate each specialists adherence to our risk management
procedures and trading guidelines, as well as to review compliance reports generated by the compliance department in monitoring and reviewing specialist trading activities. Floor captains also meet to review risk procedures and guidelines and, if
appropriate, make recommendations to the floor management committee.

Specialists. Our specialists conduct electronic and, at times,
manual auctions of our specialist stocks based upon the conditions of the marketplace. In doing so, specialists observe our risk management procedures and trading guidelines in tandem with their responsibility to create and maintain a fair and
orderly market. Specialists promptly notify a floor captain of any unusual situations or market conditions requiring a deviation from our procedures and guidelines.

On-Floor Compliance Officer. We also have an on-floor compliance officer that monitors the specialists compliance with NYSE rules throughout the day on an ad hoc basis. The on-floor compliance officer
reports his findings and on general on-floor compliance initiatives on a daily basis to our equity specialist units Chief Compliance Officer and Chief Executive Officer and provides summary updates of these efforts to the Corporate Compliance
Committee on a monthly basis. Many of our compliance and risk management activities flow from the efforts of our on-floor compliance initiative.

Electronic Exception Reports. We have implemented a system of electronic rule exception reports at our LaBranche & Co. LLC subsidiary to monitor our compliance with NYSE and SEC rules. These reports are generated on a daily
basis, from one to three days after each trading day, and are the result of significant development efforts from our technology group, with advice of our compliance and legal staff. Our compliance staff reviews these exception reports daily, and in
the event an exception is detected, the exception is researched in detail by our on-floor compliance officer or another compliance officer to determine if a compliance issue is found. If a compliance issue is detected, we make an effort to correct
the problem and conduct



74



---

training of our specialists and/or distribute compliance bulletins to ensure our specialists understand the rule and processes going forward. All detected
problems are discussed at our monthly compliance committee meetings.

We believe that the enhancements we have made to our compliance
procedures and guidelines since 2004, and on a continuous basis as circumstances warrant, have improved our risk management process.

Our
equity specialist operations on the AMEX are conducted by three equity specialists. We have one post manager on the AMEX who monitors the trading activities of the AMEX equity specialists by observing trades and reviewing positions on a real-time
basis. As a member of the floor management committee, the post manager regularly communicates with other members of the floor management committee regarding any deviations from our AMEX procedures and guidelines set by our executive operating
committee. We also have an on-floor compliance officer that monitors the specialists compliance with AMEX rules throughout the day on an ad hoc basis. The on-floor compliance officer reports his findings and on general on-floor compliance
initiatives on a daily basis to our equity specialist units Chief Compliance Officer and Chief Executive Officer and provides summary updates of these efforts to the Corporate Compliance Committee on a monthly basis. Many of our compliance and
risk management activities flow from the efforts of our on-floor compliance initiative. Our AMEX on-floor compliance officer also monitors problems with the AMEXs trading systems, which have resulted in AMEX initiatives and improvements.

Circuit Breaker Rules. The NYSE and AMEX have instituted certain circuit breaker rules intended to halt trading in all NYSE/AMEX
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. Current 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. These rules provide investors extra time to respond to severe market declines and provide us an additional opportunity to
assure compliance with our risk management procedures.

Equity Market Financial Risk

We have developed a risk management process, which is intended to balance our ability to profit from our equity specialist activities with our exposure to
potential losses. We have invested substantial capital, along with the NYSE, in real-time, on-line systems which give our management, including our chief risk officer, access to specific trading information during the trading day, including our
aggregate long and short positions and our capital and profit-and-loss information on an aggregate or per issue basis. Subject to the specialists obligation to maintain a fair and orderly market and to applicable regulatory requirements, we
constantly seek to manage our trading positions relative to existing market conditions.

A high concentration of equity specialists
principal trading revenue is generated from its ten and twenty-five most profitable NYSE specialist stocks. The percentage of our equity specialist trading revenue generated from our ten most profitable specialist stocks has increased from 13.6% to
19.6% of total principal trading revenue in 2005 and 2006, respectively.



75



---

The percentage of our equity specialist trading revenue generated from our twenty-five most profitable specialist stocks has increased from 23.8% to 35.3% of
total principal trading revenue in 2005 and 2006, respectively. However, we are not overly reliant on a particular group of specialist stocks, as the composition of our ten and twenty-five most profitable specialist stocks changes frequently.

Our equity specialist trading activities are subject to a number of risks, including risks of price fluctuations, rapid changes in the
liquidity of markets and foreign exchange risk related to American Depositary Receipts (ADRs). In any period, we may incur trading losses or gains in our specialist stocks for a variety of reasons, including price fluctuations of our
specialist stocks and fulfillment of our specialist obligations. Quantification of such losses or gains would not be meaningful as standard market studies do not capture our specialist obligations. From time to time, we may 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 significant price movement in these securities could result in an
immediate reduction of our revenues and operating profits.

Our Options, Futures and ETFs Specialist and Market-Making Risk Management
Process

As specialists in options, ETFs and futures, we have a responsibility to maintain a fair and orderly market, and trade
securities as principal out of both obligation and inclination. Our options, ETFs, futures, U.S. Government obligations and foreign currency specialist trading exposes us to certain risks, such as price and interest rate fluctuations, volatility
risk, credit risk, foreign currency movements and changes in the liquidity of markets.

Additionally, as a market-maker in options, ETFs
and futures, we also from time to time trade as principal. In our market-making function, we bring immediacy and liquidity to the markets when we participate. Our market-making activities expose us to certain risks, including, but not limited to,
price fluctuations and volatility.

Our traders purchase and sell futures, options, the stocks underlying certain positions, U.S.
Government securities and foreign currencies in an attempt to hedge market and foreign currency risk. Certain members of management, including our chief risk officer, who oversee our options, futures and ETFs specialist and market making activities
are responsible for managing these risks. These managers utilize a third-party software application to monitor specialist and market-making positions on a real-time basis. By monitoring actual and theoretical profit and loss, volatility and other
standard risk measures, these individuals seek to insure that our traders operate within the parameters set by management. Furthermore, our aggregate risk in connection with our options, futures and ETFs trading is under constant evaluation by
certain members of management and our traders, and all significant trading strategies and positions are closely monitored. When an unusual or large position is observed by the chief risk officer, he communicates the issue with senior management, who
communicates with the trader to understand the strategy and risk management behind the trade and, if necessary, determine avenues to mitigate our risk exposure. Our options, futures and ETFs trading is executed on national and foreign exchanges.
These trades clear through the Options Clearing Corporation, the National Securities Clearing Corporation or the applicable exchange clearing organization, thereby reducing potential credit risk.

The following chart illustrates how specified movements in the underlying securities prices of the
options, futures and ETFs in our specialist and market-making portfolios would have impacted profits and losses:

The modeling of the risk characteristics of our trading positions involves a number of assumptions
and approximations. While management believes that these assumptions and approximations are reasonable, there is no standard methodology for estimating this risk, and different methodologies would produce materially different estimates. The zero
percent change column represents the profit or loss our options, futures and ETFs specialist operations would experience on a daily basis if the relevant market remained unchanged.

Foreign Currency Risk & Interest Rate Risk

In connection with the trading of U.S.-registered shares of foreign issuers in connection with our cash equity specialist operations, we are exposed to varying degrees of foreign currency risk. The pricing of these
securities is based on the value of the ordinary securities as denominated in their local currencies. Thus, a change in a foreign currency rate relative to the U.S. dollar will result in a change in the value of U.S.-registered shares in which we
are the specialist.

Our ETF specialists and market-makers trade international ETFs that are denominated and settled in U.S. dollars, but
the pricing of these ETFs is also affected by changes in the relevant foreign currency rates. We, therefore, hold various foreign currencies in order to lessen the risks posed by changing foreign currency rates. In addition, LSP trades derivatives
denominated in foreign currencies, which creates exposure to foreign currency risk.

The following chart illustrates how the specified
movements in foreign currencies relative to the U.S. dollar to which our specialist and market-making activities are exposed would have impacted our profits and losses:



|                   |  |                                                                             |        |   |       |   |        |       |  |        |       |  |   |

The information in the above table is based on certain assumptions and it does not fully represent the
profit and loss exposure to changes in security prices, volatility, interest rates and other related factors.

As specialists and market
makers in options, ETFs and futures, we generally maintain large specialist and market maker positions. Historically, we have been operating in a low interest rate market. Increasing or high interest rates and or widening credit spreads may create a
less favorable operating environment for this line of business.

Execution and Clearing Risk Management Process

In connection with our specialist and market-making activities, we are engaged in various securities trading and lending activities and assume positions
in stocks, rights, options, ETFs, U.S. Government securities, futures and foreign currencies for which we are exposed to credit risk associated with the nonperformance of counterparties in fulfilling their contractual obligations pursuant to these
securities transactions. We are also exposed to market risk associated with the sale of securities not yet purchased, which can be directly impacted by volatile trading on the NYSE, AMEX and other exchanges. Additionally, in the event of
nonperformance and unfavorable market price movements, we may be required to purchase or sell financial instruments at a loss.

Our
execution and clearing activities require that we execute transactions in accordance with customer instructions and accurately record and process the resulting transactions. Any failure, delay or error in executing, recording and processing
transactions, whether due to human error or failure of our information or communication systems, could cause substantial losses for brokers, customers and/or us and could subject us to claims for losses.

Clearing activities include settling each transaction with both the contra broker and the customer. In connection with our institutional and direct
access floor brokerage activities, a transaction is settled either when the customer pays for securities purchased and takes delivery, or delivers securities sold for payment. Settling transactions for retail customers and professional investors
involves financing the transaction until the customer makes payment or, for margin accounts, advancing credit to the customer within regulatory and internal guidelines. Clearing direct access brokers transactions includes guaranteeing their
transactions to the contra broker on the exchange floor.

These clearing activities may expose us to off-balance sheet risk in the event
customers or brokers are unable to fulfill their contractual obligations and it is necessary to purchase or sell securities at a loss. For margin transactions, we may be exposed to off-balance sheet risk in the event margin requirements are not
sufficient to fully cover losses that customers may incur in their accounts.

The amount of risk related to our execution and clearance
activities is linked to the size of the transaction, market volatility and the creditworthiness of customers and brokers. Our largest transactions involve those for institutional and direct access floor brokerage customers.



78



---

We systematically monitor our open transaction risk in connection with our execution and clearing
activities, starting when the transaction occurs and continuing until the designated settlement date. Transactions that remain unsettled after settlement date are scrutinized and necessary action to reduce risk is taken. Credit risk that could
result from contra brokers defaulting is minimized since much of the settlement risk for transactions with brokers is essentially transferred to the National Stock Clearing Corporation. The credit risk associated with institutional and direct access
clearing customers is minimized since these customers have been qualified by the Depository Trust Company (DTC) or the DTC participants or have met the prime broker qualification standards at other brokerage firms. Before conducting
business with a prospective customer, senior management that oversees our execution and clearing operations, in conjunction with the related compliance department, reviews the prospective customers experience in the securities industry,
financial condition and personal background, including a background check with a risk reporting agency. For retail customers and professional investors, we seek to control the risks associated with customer activities by requiring customers to
maintain margin collateral in compliance with various regulatory and internal guidelines. We monitor margin levels daily pursuant to such guidelines and require customers to deposit additional collateral or reduce positions when necessary.

Operational Risk

Operational risk relates to the risk of loss from external events, and from failures in internal processes or information systems. In each of our business segments, we rely heavily on our information systems in managing our risk.
Accordingly, working in conjunction with the NYSE, we have made significant investments in our trade processing and execution systems. Our use of, and dependence on, technology has allowed us to sustain our growth over the past several years.
Management members and floor captains at our NYSE and AMEX equity specialist operations must constantly monitor our positions and transactions in order to mitigate our risks and identify troublesome trends should they occur. The substantial capital
we have invested, along with the NYSE, in real-time, on-line systems affords management instant access to specific trading information at any time during the trading day, including:



| |  |  | our aggregate long and short positions;
| | - |  | ---------------------------------------



| |  |  | the various positions of each of our trading professionals;
| | - |  | -----------------------------------------------------------



| |  |  | our overall position in a particular stock; and
| | - |  | -----------------------------------------------



| |  |  | capital and profit-and-loss information on an aggregate, per specialist or per issue basis.
| | - |  | -------------------------------------------------------------------------------------------

Our information systems send and receive data from the NYSE and AMEX through dedicated data feeds. 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 NYSE specialist trading profits and losses, as well as our positions. For our AMEX equity specialist operations, our in-house technology
staff has developed applications to monitor our current positions and profits and losses. Our options, futures and ETFs specialist and market-making operations utilize a third-party software application to monitor our positions and profits and
losses on a real-time basis.

We have developed and implemented a business continuity plan, which includes a comprehensive disaster
recovery plan. We have back-up disaster recovery centers in New York and New Jersey.

Legal and Regulatory Risk

Substantial legal liability or a significant regulatory action against us could have a material adverse effect on our financial condition or cause
significant harm to our reputation, which in turn could negatively affect our business prospects.

Our registered broker-dealer
subsidiaries are subject to certain regulatory requirements intended to insure their general financial soundness and liquidity. These broker-dealers are subject to SEC Rules 15c3-1, 15c3-3 and other requirements adopted and administered by both the
NYSE and AMEX.

The USA PATRIOT Act of 2001 requires U.S. financial institutions, including banks, broker-dealers, futures commission
merchants and investment companies, to implement policies, procedures and controls which are reasonably designed to detect and report instances of money laundering and the financing of terrorism. We actively monitor and update our anti-money
laundering practices.

Managements Report on Internal Control over Financial Reporting

Management of LaBranche & Co Inc., together with its consolidated subsidiaries (the Company), is responsible for establishing and maintaining
adequate internal control over financial reporting. The Companys internal control over financial reporting is a process designed under the supervision of the Companys principal executive and principal financial officers to provide
reasonable assurance regarding the reliability of financial reporting and the preparation of the Companys financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

As of the end of the Companys 2006 fiscal year, management conducted an assessment of the effectiveness of the Companys internal control over financial
reporting based on the framework established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has determined
that the Companys internal control over financial reporting as of December 31, 2006 is effective.

Our internal control over financial reporting
includes policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and disposition of assets; provide reasonable assurances that transactions are recorded as necessary
to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles and that receipts and expenditures are being made only in accordance with authorizations of management; and provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Companys assets that could have a material effect on our consolidated financial statements.

Managements assessment of the effectiveness of the Companys internal control over financial reporting as of December 31, 2006 has been audited by KPMG
LLP, an independent registered public accounting firm, as stated in their report, appearing on page F-3 of this Annual Report on Form 10-K, which express an unqualified opinion on managements assessment of the effectiveness of the
Companys internal control over financial reporting as of December 31, 2006, and an unqualified opinion on the effectiveness of the Companys internal control over financial reporting as of December 31, 2006.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

LaBranche & Co Inc.:

We have audited the accompanying consolidated statements of financial condition of LaBranche & Co Inc. and subsidiaries as of December 31,
2006 and 2005, and the related consolidated statements of operations, changes in stockholders equity and cash flows for each of the years in the three-year period ended December 31, 2006. In connection with our audits of the consolidated
financial statements, we have also audited the financial statement schedule. These consolidated financial statements and the related financial statement schedule are the responsibility of the Companys management. Our responsibility is to
express an opinion on these consolidated financial statements and the related financial statement schedule based on our audits.

We conducted our audits in
accordance with the standards of the Public Company Accounting Oversight Board (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 consolidated financial statements referred to above present fairly, in all material respects, the financial position of LaBranche & Co Inc. and subsidiaries as of December 31, 2006 and 2005, and the results of their operations and
their cash flows for each of the years in the three-year period ended December 31, 2006, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related December 31, 2006 and 2005 financial statement
schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of LaBranche & Co Inc. and subsidiaries internal control over
financial reporting as of December 31, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 1,
2007 expressed an unqualified opinion on managements assessment of, and the effective operation of, internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

LaBranche & Co Inc.:

We have audited management's assessment, included in the accompanying Managements Report on Internal Control over Financial Reporting,that
LaBranche & Co Inc. and subsidiaries maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). LaBranche & Co Inc. and subsidiaries management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness
of internal control over financial reporting. Our responsibility is to express an opinion on management's assessment and an opinion on the effectiveness of the Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting,
evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a
reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management
and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

|2. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
|-- | ------------------------------------------

Basis of
Presentation

The preparation of consolidated financial statements in conformity with U.S. 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.
Actual results could differ from these estimates.

Certain of the Companys December 31, 2005 statement of financial condition
balances have been reclassified to conform to the presentation in the current period, including (a) receivables from and payables to broker-dealers and clearing organizations and (b) financial instruments owned, and sold but not yet
purchased, at fair value. Certain of the Companys December 31, 2005 and 2004 statement of operations balances have been reclassified to conform to the presentation in the current period in order to net interest expense (including margin
interest expense) against interest income to determine the Companys net revenues.

The consolidated financial statements include the
accounts of the Holding Company and its wholly-owned subsidiaries. All significant inter-company balances and transactions have been eliminated in consolidation.

Cash and Cash Equivalents

Cash and cash equivalents include all demand deposits held in banks, highly liquid
investments with original maturities of 90 days or less and currency positions that are being held in the prime brokerage account at the Companys clearing broker for its specialist and market-making operations. Certain portions of these
balances are used to meet regulatory requirements (see Note 8).

Securities Transactions

Principal securities transactions and the related gains and losses are recorded on a trade date basis. Customer securities transactions are recorded on a
settlement date basis and the related revenues and expenses are recorded on a trade date basis. Receivables from, and payables to, customers represent amounts due from or to customers of the Company in connection with cash and margin securities
transactions. The value of certain receivables collateralized by customers securities held by the Company and by other broker-dealers for delivery to the Company, is not reflected in the accompanying consolidated financial statements.
Corporate equities, options, ETFs, futures and other securities owned, and securities sold, but not yet purchased, are reflected at market value and unrealized gains and losses are presented as a component of Net gain on principal
transactions. U.S. Government obligations, which are reported under Securities owned, at fair value are reflected at market value. U.S. Government obligations included under Cash and cash equivalents, together with
related interest receivable, which is reported under Other assets, approximate market value. Interest income related to U.S. Government obligations is included in RevenuesInterest. Dividend income and expense and
Securities and Exchange Commission ("SEC") fees, as well as gains and losses from

---

the trading of foreign currencies, are also presented as a component of Net gain on principal transactions. Dividend income and expense are
recognized on the record date, which does not differ materially from the ex-date. In the normal course of business, the Company is permitted to use client margin securities to finance customer securities transactions, subject to certain regulatory
guidelines. The market value for equity securities, ETFs and futures contracts is based on the closing price posted on the primary exchange on which they are traded. The market value of exchange-traded options is based on the national best bid/offer
as determined by the Companys options clearing agents.

Investments in non-marketable securities consist of investments in equity
securities of private companies, limited liability company interests and limited partnership interests, and are included as part of Other assets on the consolidated statements of financial condition. These investments do not have readily
available price quotations. Non-marketable investments are accounted for under the equity method, for those investments in which the Companys voting interest is 20% to 50%, or at fair value. In determining fair value, management of the Company
considers third-party transactions evidencing a change in value, the financial performance of the investee, or any specific rights associated with the investment such as conversion features. Changes in fair value are recognized if the expected
realizable value of the investment differs from its carrying value.

Corporate equities owned, but not readily marketable, consists of our
ownership of 3,126,903 shares of the restricted common stock of NYSE Group, Inc. common stock. APB No. 29 (as amended) provides guidance on exchanges of assets in a non-monetary transfer. Accounting for non-monetary assets acquired in a
substantially non-monetary exchange is at times based on cost or fair value of the assets relinquished and at times on the fair value of the assets received in the exchange. Based on the guidance under APB No. 29, the Company valued the shares
of NYX stock received immediately after the exchange at fair value, which was deemed to be the value of the shares on the first day trading commenced for NYX stock. After the consummation of the NYSE/Archipelago merger, the Company has accounted for
its investment in the NYX stock acquired in the NYSE/Archipelago merger at the estimated fair value of such restricted shares pursuant to the American Institute of Certified Public Accountants Audit and Accounting GuideBrokers and Dealers
in Securities.The shares of NYX stock received in the NYSE/Archipelago Merger are subject to a three-year restriction on transfer. The restriction will be removed in equal one-third installments on each of March 7, 2007, 2008 and
2009, unless the restrictions are removed earlier by the NYSE Group in its sole discretion (See note 11). Equity method investments are also assessed for other-than-temporary impairment as considered necessary.

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 plus accrued interest. It is the policy of the Company to obtain possession of collateral with market value equal to or in excess of the principal amount loaned under resale agreements. Collateral is valued daily, and the Company may require
counterparties to deposit additional collateral when necessary. The market value of securities received for securities purchased under agreements to resell at December 31, 2006, exceeded total cash paid. None of the securities received was
subsequently repledged or resold.

Intangible Assets

Intangible assets are comprised of the Companys specialist stock lists, trade name and goodwill acquired in connection with various acquisitions and the limited partner buyout that occurred in 1999 concurrent
with the Companys reorganization from partnership to corporate form. For material acquisitions through March 2001, the allocations of purchase price among these assets and determinations of their respective useful lives were based on
independent appraisals. The useful lives of the acquired specialist stock lists were determined based upon analysis of historical turnover characteristics of the specialist stocks comprising these lists. For acquisitions subsequent to March 2001,
the allocations of purchase price and determinations of useful lives were based upon managements analysis of revenues, consideration paid, common stock listings and other relevant data and ratios. This information was analyzed and compared to
the results of the independent appraisals conducted in connection with the acquisitions prior to April 2001.

GoodwillIn
accordance with SFAS No. 142, Goodwill and Other Intangible Assets (SFAS No. 142), goodwill is not amortized. SFAS No. 142 requires that goodwill be tested annually for impairment (or more frequently when
events or changes in circumstances indicate impairment testing may be necessary) by applying a fair value-based test. This test involves the comparison of the fair value of a reporting unit to its carrying value. If the carrying value of the
reporting unit exceeds its estimated fair value, there is an indication that goodwill might be impaired, which requires additional testing. This additional testing entails estimating the implied fair value of reporting unit goodwillthrough the
use of discounted cash flows analysis and other measuresand comparing this implied fair value of reporting unit goodwill to its carrying value. Any excess of carrying value of reporting unit goodwill over its implied fair value is recognized
as an impairment loss. For the years ended December 31, 2006, 2005 and 2004, the Company recorded goodwill impairment charges of $-0-, $-0- and $37.6 million, respectively (see Note 6).

Trade NameUnder SFAS No. 142, the acquired trade name is not amortized. The Company tests its trade name for impairment
annually (or more frequently if events or changes in circumstances indicate that the asset might be impaired) in conjunction with its goodwill impairment assessment. If the carrying amount of the trade name exceeds its fair value, an impairment loss
is recognized in an amount equal to that excess. As of December 31, 2006, the Companys trade name was not impaired.

Specialist Stock ListsAcquired specialist stock lists are amortized over their respective useful lives. The Company assesses its specialist stock lists for possible impairment in accordance with SFAS No. 144,
Accounting for the Impairment or Disposal of Long-Lived Assets (SFAS No. 144). Pursuant to SFAS No. 144, the Company evaluates its acquired stock lists for potential impairment whenever events or changes in
circumstances indicate that their carrying amount may not be fully recoverable. An impairment loss, calculated as the difference between the estimated fair value and the carrying value of the acquired stock lists, is recognized if the expected
undiscounted cash flows relating to the acquired stock lists are less



F-13



---

than the corresponding carrying value. In conjunction with this evaluation, the Company also reviews the reasonableness of the specialist acquired stock
lists remaining useful lives. Any revisions to amortization periods are considered when developing the aforementioned undiscounted cash flows. As of December 31, 2006, the Companys stock lists were not impaired pursuant to SFAS
No. 144.

Exchange Memberships

In accordance with the American Institute of Certified Public Accountants (AICPA) Audit and Accounting GuideBrokers and Dealers in Securities, exchange memberships owned by the Company are originally carried
at cost or, if an other-than-temporary impairment in value has occurred, at adjusted cost, which reflects managements estimate of fair value. In determining whether an other-than-temporary decline in value has occurred, the Company uses
Emerging Issues Task Force (EITF) Issue No. 03-1, The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments,and Section M of Topic 5 of the SEC staff accounting bulletin series (SAB
No. 59) as analogous guidance. For the years ended December 31, 2006, 2005 and 2004, the Company recognized impairment losses of $-0-, $-0- and $18.3 million, respectively, on owned exchange memberships (see Note 5).

On March 7, 2006, Archipelago Holdings, Inc. (Archipelago) and the NYSE consummated a merger in which they combined their businesses and
became wholly-owned subsidiaries of NYSE Group, Inc., a newly-created, for-profit and publicly-traded holding company (NYSE Group). Prior to the NYSE/Archipelago merger, the Companys specialists conducted business on the floor
of the NYSE through ownership or lease of NYSE memberships. Following the NYSE/Archipelago merger, trading licenses replaced the prior trading rights provided by the ownership or lease of an NYSE membership. In January 2006, the Company participated
in a Dutch auction for these trading licenses and successfully bid for 90 trading licenses in the Companys Specialist and Market-Making segment (five additional licenses were obtained for the Companys Execution and Clearing
segment operations). The fee per annum for these trading licenses in 2006 was $49,290 per license.

Prior to March 7, 2006 certain
employees of the Company contributed the use of nine NYSE memberships to the Company. These memberships were subordinated to claims of general creditors were carried at market value with a corresponding amount recorded as subordinated liabilities.
The Company made lease payments to these employees for the use of the NYSE memberships at a rate that was commensurate with the rent paid to non-affiliated parties for the use of their NYSE memberships.

The Company leases additional memberships on the AMEX and the Chicago Board Options Exchange® (CBOE) from non-affiliated parties and makes lease payments to these
parties at prevailing market rates. Subsequent to the NYSE merger on March 7, 2006, the Company no longer leases NYSE memberships.

Income Taxes

The Company accounts for income taxes using the asset and liability method in accordance with SFAS No. 109, Accounting
for Income Taxes. SFAS No. 109 requires the recognition of tax benefits or expenses based on the estimated future tax effects of temporary



F-14



---

differences between the financial statement and tax bases of an entitys assets and liabilities. The effect on deferred taxes of a change in tax rates
is recognized as income in the period that includes the enactment date. Valuation allowances are established to reduce deferred tax assets to the amount that more likely than not will be realized. The Companys deferred tax assets are presented
as a component of Other assets in the consolidated statements of financial condition. Tax contingencies, and related employment tax contingencies, are included under Other liabilities on the 2006 consolidated statement of
financial condition. Contingent liabilities related to income taxes are recorded when the criteria for loss recognition under SFAS No. 5, Accounting for Contingencies are met.

Legal Contingencies

The Company records
reserves related to legal proceedings in Other liabilities. Such reserves are established and maintained in accordance with SFAS No. 5, Accounting for Contingencies and FASB Interpretation No. 14, Reasonable
Estimation of the Amount of a Loss, an Interpretation of SFAS Statement No. 5 and SEC Staff Accounting Bulletin No. 92, Accounting and Disclosures Relating to Loss Contingencies. The determination of these reserve amounts
requires significant judgment on the part of management. Each legal proceeding is reviewed with counsel in each accounting period and the reserve is adjusted as deemed appropriate by management.

Depreciation and Amortization

Depreciation of
office equipment is calculated using the straight-line method over estimated useful lives of 5 years. Amortization of leasehold improvements is calculated using the term of the related lease. Estimated useful lives of leasehold improvements range
from 1 to 15.25 years.

Acquired specialist stock lists are amortized over useful lives ranging from 15 to 40 years.

Share-Based Compensation

Effective
January 1, 2003 until December 31, 2005, the Company accounted for stock-based employee compensation in accordance with the prospective method prescribed by SFAS No. 148, Accounting for Stock-Based Compensation-Transition and
Disclosure, an Amendment of FASB Statement No. 123. Under this method, compensation expense is recognized over the related service periods based on the fair value, as of the date of grant, of stock options and restricted stock units
granted to employees on or after January 1, 2003. Such stock options and restricted stock units are included in Stockholders equity under SFAS No. 148 when services required from employees in exchange for the awards are
rendered and expensed.

Had the Company recognized compensation expense over the relevant service period under the fair value-based method
of SFAS No. 123 with respect to stock options granted for the year ended December 31, 2005 and prior years, net income (loss) applicable to common stockholders would have been reduced (or increased, where applicable), resulting in pro
forma

The effect of applying SFAS No. 123 in the pro forma disclosure above may not be
representative of the potential effect stock-based compensation would have on net income (loss) in future periods.

In December 2004, the
FASB issued SFAS No. 123(R), Share Based Payment. SFAS No. 123(R) is a revision of SFAS No. 123, Accounting for Stock-Based Compensation and supersedes APB opinion No. 25, Accounting for Stock Issued
to Employees and amends SFAS No. 95, Statement of Cash Flows. SFAS No. 123(R) requires compensation costs related to share-based payment transactions to be recognized in the financial statements over the period that an
employee provides service in exchange for the award. SFAS No. 123(R) was adopted as of January 1, 2006, using the modified prospective method. SFAS No. 123(R) requires expected forfeitures to be included in determining share-based
employee compensation expense. Prior to the adoption of SFAS No. 123(R), forfeiture benefits were recorded as a reduction to compensation expense when an employee left the firm and forfeited the award. In the first quarter of 2006, the Company
recorded a benefit for expected forfeitures on all outstanding share-based awards. The transition impact of adopting SFAS No. 123(R) as of the first day of the Companys 2006 fiscal year, including the effect of accruing for expected
forfeitures on outstanding share-based awards, was not material to the Companys financial condition, results of operations, earnings per share or cash flows for the twelve months ended December 31, 2006 (see Note 14).

Recent Accounting Pronouncements

Accounting for Tax Uncertainties

In July 2006, the FASB issued Interpretation No. 48 Accounting for Uncertainty
in Income Taxes (FIN 48). FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 also
provides guidance on de-recognition, measurement,



F-16



---

classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 will be effective beginning in the first quarter of
2007. The Company has evaluated the potential impact of FIN 48, and at this time, management believes contingent tax reserve and current and deferred income taxes are adequately stated in conformity with FAS 109 and FIN 48.

Fair Value Measurements

In September
2006, the FASB issued SFAS No. 157, Fair Value Measurements (SFAS 157). SFAS 157 defines fair value, establishes a framework for measuring fair value and enhances disclosures about fair value measurements required under
other accounting pronouncements, but does not change existing guidance as to whether or not an instrument is carried at fair value. SFAS 157 nullifies the guidance in EITF 02-3 which precluded the recognition of a trading profit at the inception of
a derivative contract, unless the fair value of such derivative is obtained from a quoted market price, or other valuation technique incorporating observable market data. SFAS 157 also precludes the use of a liquidity or block discount, when
measuring instruments traded in an active market at fair value. SFAS 157 requires that costs related to acquiring financial instruments carried at fair value should not be capitalized, but rather should be expensed as incurred. SFAS 157 also
clarifies that an issuers credit standing should be considered when measuring liabilities at fair value. SFAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, with earlier application
permitted and encouraged. SFAS 157 must be applied prospectively, except that the provisions related to block discounts and the guidance in EITF 02-3 are to be applied as a one time cumulative effect adjustment to opening retained earnings in the
first interim period for the fiscal year in which SFAS 157 is initially applied. The Company currently is evaluating the potential impact, if any, that the adoption of SFAS 157 will have on its consolidated financial statements.

Accounting for Fair Value Option for Financial Assets and Financial Liabilities

In February 2007, the FASB issued SFAS No. 159, Accounting for Fair Value Option for Financial Assets and Financial Liabilities
(SFAS 159). SFAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate
volatility in reported



F-17



---

earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. The Company currently
reports the majority of its financial assets and liabilities at fair value in compliance with industry guidelines for brokers and dealers in securities. The Company has a significant investment in intangibles and goodwill as well as public debt
which is not accounted for at fair value. The Company believes SFAS 159 exempts intangible assets and goodwill from fair value reporting. The Company is currently evaluating the potential impact if any that the adoption of SFAS 159 will have on its
financial statements.

|4. | NON-MARKETABLE SECURITIES
|-- | -------------------------

During 2006 and 2005,
the Company recognized a gain of approximately $0.1 million and $11.0 million, respectively, related to its non-marketable investments. Included in the 2005 amount was $9.6 million related to the release of an escrow account held in connection with
a 2004 disposition of an investment. At December 31, 2006 and 2005, non-marketable securities totaling $7.3 million and $7.1 million, respectively, are included in Other assets on the consolidated statements of financial condition.

|-- | --------------------

As of December 31, 2005,
the Company owned 39 NYSE memberships out of a total 1,366 NYSE memberships, representing a 2.9% ownership interest in the NYSE. The Company accounted for its investment in these memberships under the adjusted cost method since its
inception.

In the NYSE/Archipelago merger, each holder of an NYSE membership became entitled to receive in exchange
for the NYSE membership $300,000 in cash and 80,177 shares of NYSE Group common stock (the NYX stock). The Companys 39 NYSE memberships were converted into the right to receive an aggregate of $11.7 million cash and 3,126,903
shares of NYX stock. The $11.7 million cash distribution was treated as monetary consideration for which a realized gain was recognized in the first quarter of 2006.

Prior to the closing of the NYSE/Archipelago merger, the Company participated in a Dutch auction for trading licenses, successfully bidding for 95 trading licenses at an annual price of $49,290 each, the
minimum bid accepted by the NYSE. The licenses became effective for trading on the NYSE on March 8, 2006. As of December 31, 2006 the Company had surrendered 13 of these licenses. The costs of the trading licenses for 2006 was
approximately $1.2 million per quarter and are included in lease of exchange memberships and trading license fees in the Companys Consolidated Statement of Operations.



|6. | GOODWILL AND IDENTIFIABLE INTANGIBLE ASSETS
|-- | -------------------------------------------

Goodwill

As of December 31, 2006 and 2005, as required by SFAS No. 142, the Company tested goodwill for
impairment. It was determined that the fair value of implied goodwill (Step 2) exceeded its carrying value and was therefore not impaired. Management regularly reviews any changes in facts and circumstance, as required by SFAS No. 142, that
could reduce the fair value of implied goodwill below its carrying amount.

Identifiable Intangible Assets

The Companys acquired specialist stock lists are amortized over their respective lives ranging from 15 to 40 years, with a weighted-average
amortization period of 39.6 years. The gross carrying amount, accumulated amortization and net carrying amount of acquired specialist stock lists are set forth below as of December 31:



|                         |  |      |         |   |      |   |         |

Amortization expense was approximately $10.4 million for each of the years ended December 31,
2006, 2005 and 2004. Estimated amortization expense for the existing acquired specialist stock lists is $10.4 million for each of the fiscal years ending December 31, 2007 through December 31, 2011.

The 2006 net increase in deferred tax assets was principally attributable to the valuation
allowance on the NYX shares received as part of the NYSE/Archipelago merger. The carryback of a Federal 2004 net operating loss to 2002 resulted in an $18.3 million refund and a 2005 state/city NOL utilization of $27.7 million. There is no valuation
allowance recorded against the deferred tax assets. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be deductible. Based on the
Companys level of historical taxable income, future reversals of existing taxable differences and all other available evidence, management believes that the deferred tax assets will more likely than not be realized.

The 2006 net increase in deferred tax liabilities is due primarily to the unrealized gain for tax
purposes on the Companys investment in NYX restricted stock of $123.4 million.

The Company's effective tax rate differs from the
U.S. Federal statutory income tax rate of 35.0% as set forth below:

In 2006, the Company recognized a tax benefit of $4.1 million for a dividend received deduction on
amounts paid by the NYSE relating to the NYSE/Archipelago merger. The Company has a New York State and City net operating loss carryover from 2004 of $24.5 million. The Company anticipates that it will utilize approximately $1.5 million for its 2006
tax return.

In 2005, the Company recognized a tax benefit of $7.8 million for a tax rate change and state tax law change and $1.3 million
for a reduction in tax liabilities due to the close of the statute of limitations with respect to a prior federal tax year.

In 2004, the
Holding Company generated a tax net operating loss of $52.5 million that was carried-back to 2002 and resulted in a refund of $18.3 million that was received in April 2005. New York State and City, the principal state and local tax filing
jurisdictions of the Holding Company, only allow a carryforward for 20 years.

In July 2006, the FASB issued FASB Interpretation
No. 48, Accounting for Uncertainty in Income Taxesan interpretation of FASB Statement No. 109 (FIN 48), which will become effective for years beginning after December 15, 2006. The Interpretation
prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be
more-likely-than-not to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. The Company
believes that the adoption of FIN 48 will result in no change to shareholders equity as of January 1, 2007.



|8. | CAPITAL AND NET LIQUID ASSET REQUIREMENTS
|-- | -----------------------------------------

LaBranche & Co. LLC, as a specialist and member of the NYSE and AMEX, is subject to the
provisions of SEC Rule 15c3-1, as adopted and administered by the SEC, NYSE and AMEX. LaBranche & Co. LLC is required to maintain minimum net capital, as defined, equivalent to the greater of $100,000 or1/15of aggregate
indebtedness, as defined.



F-21



---

As of December 31, 2006 and December 31, 2005, LaBranche & Co. LLCs net capital,
as defined under SEC Rule 15c3-1, was $365.5 million and $459.8 million, respectively, which exceeded the minimum requirements by $364.3 million and $458.1 million, respectively. LaBranche & Co. LLCs aggregate indebtedness to net
capital ratio on those dates was .05 to 1 and .05 to 1, respectively.

The NYSE generally requires its specialist firms to maintain a
minimum dollar regulatory capital amount in order to establish that they can meet, with their own net liquid assets, their position requirement. Prior to September 1, 2006 LaBranche & Co. LLCs and LSPS net liquid asset
requirements were combined. The combined requirement was calculated by LaBranche & Co. LLC, and this requirement was met with the LLCs net liquid assets. Subsequent to September 1, 2006, each company was required to compute and
meet its own requirement. As of December 31, 2006 LaBranche & Co. LLCs NYSE minimum required dollar amount of net liquid assets, as defined, was $323.3 million and its actual net liquid assets, as defined, were $360.9 million. As
of December 31, 2005, LaBranche & Co. LLCs and LSPS combined NYSE minimum required dollar amount of net liquid assets, as defined was $447.0 million, and LaBranche & Co. LLCs actual net liquid assets, as
defined were $459.3 million. As of December 31, 2006 and December 31, 2005, LaBranche & Co. LLCs actual net liquid assets exceeded the net liquid assets requirement, thus satisfying its respective net liquid asset
requirement as of those dates. On July 25, 2006, the SEC approved a reduction of the minimum dollar regulatory capital for a specialist in cash equities and increased the requirement for a specialist in ETFs. This reduction is to be effected in
four quarterly installments. After each installment, LaBranche & Co. LLC paid a dividend to the Holding Company in the amount of $49 million on September 1, 2006 and $57 million on December 1, 2006. As a result, the Company
anticipates that LaBranche & Co. LLCs aggregate required minimum NLA will be significantly reduced in additional installments on March 1, 2007 and June 1, 2007.

The AMEX generally requires its equity specialist firms to maintain a cash or liquid asset position equal to the greater of (a) $1.0 million or
(b) an amount sufficient to assume a position of sixty trading units of each security in which the equity specialist is registered. As of December 31, 2006 and December 31, 2005, LaBranche & Co. LLC satisfied the AMEX equity
specialist liquid asset requirements.

|9. | SHORT TERM AND LONG TERM DEBT
|-- | -----------------------------

Debt
Extinguishment and Refinancing

On May 18, 2004, in connection with the refinancing of certain of the Companys indebtedness,
the Company repurchased approximately $93.1 million of its then-outstanding $100.0 million aggregate principal amount 9.5% senior notes due 2004 (the 2004 Notes) and



F-23



---

approximately $236.4 million of its then-outstanding $250.0 million aggregate principal amount 12.0% senior subordinated notes due 2007 (the 2007
Notes and, together with the 2004 Notes, the Old Notes), and paid for related consents delivered by the holders of the Old Notes on or prior to April 19, 2004. The aggregate purchase price paid by the Company for the Old Notes
was approximately $386.9 million, which included the purchase price, premium and consent payments of approximately $49.0 million in the aggregate, and accrued but unpaid interest on the Old Notes up to, but not including, the settlement
date. Upon the completion of this debt repurchase and consent solicitation, the indentures governing the remaining outstanding Old Notes were stripped of substantially all restrictive covenants, certain events of default and other related
provisions.

In order to fund the repurchase of the Old Notes and related consent solicitation, the Company issued $460.0 million
aggregate principal amount of new senior notes (collectively, the Original Senior Notes) to qualified institutional buyers in the United States pursuant to Rule 144A under the Securities Act of 1933, as amended (the Securities
Act), and outside the United States pursuant to Regulation S under the Securities Act. The Original Senior Notes consisted of 9.5% Senior Notes due 2009 in the aggregate principal amount of $200.0 million (the Original 2009
Notes") and 11.0% Senior Notes due 2012 in the aggregate principal amount of $260.0 million (the Original 2012 Notes).

On
September 10, 2004, pursuant to a registration rights agreement between the initial purchaser of the Original Senior Notes and the Company, the Company offered to exchange (i) its 9.5% Senior Notes due 2009 that have been registered under
the Securities Act (the 2009 Senior Notes), for an equal principal amount of outstanding Original 2009 Notes and (ii) its 11.0% Senior Notes due 2012 that have been registered under the Securities Act (the 2012 Senior
Notes, and together with the 2009 Senior Notes, the Senior Notes), for an equal principal amount of outstanding Original 2012 Notes.

The exchange offer expired on October 22, 2004, with the holders of 98.5%, or $197.0 million aggregate principal amount, of Original 2009 Notes having tendered their Original 2009 Notes for exchange, and the
holders of 100.0%, or $260.0 million aggregate principal amount, of the Original 2012 Notes having tendered their Original 2012 Notes for exchange. The new Senior Notes represent the same indebtedness as the Original Senior Notes that were exchanged
and have been issued under the same indenture. All subsequent references to the term 2009 Senior Notes include the $3.0 million principal amount of Original 2009 Notes that were not tendered in the exchange offer and remain outstanding.

The Senior Notes were issued pursuant to a new indenture that is similar to the indentures that governed the Old Notes prior to their
amendment in connection with the May 2004 debt refinancing. The new indenture includes certain covenants that, among other things, limit the Companys ability to make certain investments, engage in transactions with stockholders and affiliates,
create liens on the Companys assets and sell assets or engage in mergers and consolidations, except in accordance with certain specified conditions. In addition, the Companys ability to incur additional indebtedness (other than certain
permitted indebtedness), pay dividends, redeem stock or repurchase subordinated indebtedness prior to maturity will be limited if the Companys consolidated fixed charge coverage ratio is at or below a threshold of 2.00:1 on and
after December 31, 2004. The consolidated fixed charge coverage ratio reflects a



F-24



---

comparison between (1) the Companys consolidated earnings before interest, taxes, depreciation and amortization expenses, or EBITDA,
and (2) the sum of the Companys consolidated interest expense and a tax-effected multiple of any dividend payments that the Company might make with respect to preferred stock. As of December 31, 2006, the Companys consolidated
fixed charge coverage ratio was approximately 1.60:1. The indenture governing the Senior Notes provides for certain exceptions to the limitations on restricted payments, including, for example, the Companys July 2004 repurchase of all
then-outstanding shares of its Series B preferred stock, repurchase of the Companys Senior Notes, and any restricted payments up to an aggregate of $15.0 million over the life of the indenture.

In addition, under the indenture governing the Senior Notes, if, at any time, the Companys cumulative restricted payments since
May 18, 2004 generally are greater than (i) the sum of (A) 50.0% of the Companys cumulative consolidated net income, as defined in the indenture, since July 1, 2004 (or, if such calculation is a loss, minus 100.0% of such
loss), and (B) 100.0% of the net cash proceeds received from any issuance or sale of the Companys capital stock since July 1, 2004, plus (ii) $15.0 million, the Company will not be entitled to make a restricted
payment at such time. As of December 31, 2006, the Companys cumulative consolidated net income since July 1, 2004 was $176.4 million, and the Company had received approximately $1.4 million upon the exercise of options since
July 1, 2004. However, because the Companys Fixed Charge Coverage Ratio as of December 31, 2006 was less than 2.00:1, the Company was able to make restricted payments up to the minimum $15 million restricted payment
allowance.

The indenture governing the Senior Notes permits the Company to redeem some or all of the 2009 Senior Notes on or after
May 15, 2007 and some or all of the 2012 Senior Notes on or after May 15, 2008 at varying redemption prices, depending on the date of redemption. In addition, the Company has the option to redeem up to 33.0% of the aggregate principal
amount of the 2009 Senior Notes at a redemption price of 109.5% and up to 33.0% of the aggregate principal amount of the 2012 Senior Notes at a redemption price of 111.0% using the proceeds of certain equity offerings which the Company may complete
on or prior to May 15, 2007. Under the terms of the indenture, if the Company sells substantially all of its assets or experiences specific kinds of changes in control, the Company will be required to offer to repurchase Senior Notes, on a pro
rata basis, at a price in cash equal to 101.0% of their principal amount, plus accrued and unpaid interest, if any, to the date of purchase.

On August 2, 2004, the Company sold its investment in Lava Trading Inc. (Lava) as part of the acquisition of Lava by Citigroup Financial Products, Inc. Upon the closing of the Lava acquisition, which constituted an
asset sale under the terms of the Indenture, the Company received $39.0 million in cash. Under the Lava acquisition agreement, additional consideration of approximately $9.6 million was being held in escrow to secure the Companys
indemnification obligations as a stockholder of Lava. The full amount of this escrow was released to the Company on October 31, 2005. An additional $640,960 was received by the Company on or before October 31, 2005 in connection with the
settlement by Lava of certain tax and insurance claims. Pursuant to the terms of the Indenture, therefore, on October 24, 2006, the Company offered to purchase outstanding Senior Notes in the aggregate principal amount of up to $6.6 million.
This offer expired on November 22, 2006, with $26,000 principal amount of outstanding Senior Notes having been tendered. Following the closing of this transaction and the



F-25



---

closings of other previous offers to repurchase with immaterial tenders of Senior Notes, approximately $199.8 million aggregate principal amount of Senior
Notes due 2009 remained outstanding and approximately $260.0 million aggregate principal amount of Senior Notes due 2012 remained outstanding.

The Companys short term and long term debt as of December 31, 2006 and 2005 were as follows:

Short Term Debt

As of December 31, 2006, the Companys short-term debt consisted of $3.0 million principal amount due June 3, 2007, with
respect to the five subordinated notes in the initial aggregate principal amount of $15.0 million described below in Note 10 Subordinated Liabilities, $13.6 million aggregate principal amount of remaining 2007 Notes, the carrying value
of which was approximately $13.5 million, and eight separate $1.0 million promissory notes (this indebtedness accrued interest at the rate of 10.0% per year until August 7, 2003 and thereafter accrues interest at a rate of 9.0% per
year, payable semiannually, and maturing on August 7, 2007).

As of December 31, 2005, the Company had no short-term debt other
than the $3.0 million principal amount due on June 3, 2006, with respect to the five subordinated notes in the initial aggregate principal amount of $15.0 million described below in Note 10. Subordinated Liabilities.

Long Term Debt

As of
December 31, 2006, long term debt of the Company was comprised of $459.8 million aggregate principal amount of Senior Notes. Debt issuance costs, totaling approximately $5.5 million for the 2009 Senior Notes and approximately $7.2 million for
the 2012 Senior Notes, are being amortized over the life of the Senior Notes as an adjustment to interest expense. For the year ended December 31, 2006, interest expense related to the Senior Notes totaled $49.3 million.

As of December 31, 2005, long term debt of the Company was comprised of (a) $459.8 million aggregate principal amount of Senior Notes,
(b) $13.6 million aggregate principal amount of remaining 2007 Notes, the carrying value of which is approximately $13.5 million, and (c) eight separate $1.0 million promissory notes (this indebtedness accrued interest at the rate of
10.0% per year until August 7, 2003 and thereafter accrues interest at a rate of 9.0% per year, payable semiannually, and maturing on August 7, 2007). Debt issuance costs, totaling approximately $5.5 million for the 2009 Senior
Notes and approximately $7.2 million for the 2012 Senior Notes, are being amortized over the life of the Senior Notes as an adjustment to interest expense. For the year ended December 31, 2005, interest expense related to the Senior Notes
totaled $49.2 million. For the years ended December 31, 2005, 2004 and 2003, interest expense related to the $8.0 million promissory notes totaled $0.7 million, $0.7 million and $0.8 million, respectively.

|10. | SUBORDINATED LIABILITIES
|--- | ------------------------

LaBranche & Co.
LLC is a party to subordinated loan agreements under which it has incurred indebtedness approved by the NYSE for inclusion as net capital, as defined. Interest is payable quarterly at an annual rate of 10.0%. Three agreements representing
approximately $1.1 million mature within the first six months of 2007, and four agreements representing approximately $2.3 million mature within the last six months of 2007. These subordinated loans all have automatic rollover provisions, and each
scheduled maturity date will be extended an additional year, unless the lender gives LaBranche & Co. LLC seven months advance notice that the maturity date will not be extended. LaBranche & Co. LLC is entitled to prepay these
subordinated loans without penalty under the terms of the agreements relating thereto. Interest expense incurred on these and other similar subordinated loan agreements which have been repaid was approximately $0.3 million for the year ended
December 31, 2006 and $0.4 million and $0.5 million for the years ended December 31, 2005 and 2004, respectively.

In 1998,
LaBranche & Co. LLC issued five subordinated notes representing aggregate indebtedness of $15.0 million, which mature in equal installments of $3.0 million payable on June 3, 2004, 2005, 2006, 2007 and 2008, and bear interest at an
annual rate of 7.7%, payable on a quarterly basis. On June 3, 2006, LaBranche & Co. LLC repaid $3.0 million of these subordinated notes. As of December 31, 2006, $6.0 million remained outstanding under these subordinated notes,
which are senior to all other subordinated notes of LaBranche & Co. LLC. The agreements covering these subordinated notes require LaBranche & Co. LLC to comply with certain covenants that, among other things, restrict the type of
business in which LaBranche & Co. LLC may engage, set certain net capital levels and prohibit restricted payments, as defined. Interest expense incurred on these subordinated notes for the years ended December 31, 2006, 2005 and 2004
was approximately $0.6 million, $0.8 million and $1.0 million, respectively.



|11. | NYSE GROUP RESTRICTED STOCK EXCHANGE TRANSACTION
|--- | ------------------------------------------------

As of December 31, 2005, the Company owned 39 NYSE memberships out of a total 1,366 NYSE memberships, representing a 2.9% ownership interest in the NYSE. The Company accounted for its investment in these NYSE memberships under the
adjusted cost method since its inception. On March 7, 2006, the NYSE and Archipelago completed the NYSE/Archipelago merger.

In the
NYSE/Archipelago merger, each holder of an NYSE membership became entitled to receive in exchange for the NYSE membership $300,000 in cash and 80,177 shares of NYX



F-27



---

stock. In addition, immediately prior to the consummation of the NYSE/Archipelago merger, the NYSE announced the declaration of a permitted
dividend payable with respect to each NYSE membership in the amount of approximately $70,570 ($2.7 million in total for the Companys 39 NYSE memberships), which was equivalent to the memberships pro rata portion of the NYSEs
excess cash, as defined in the merger agreement governing the NYSE/Archipelago merger. The Company received the permitted dividend with respect to each of its 39 NYSE memberships on March 14, 2006.

In the NYSE/Archipelago merger, the Companys 39 NYSE memberships were converted into the right to receive an aggregate of $11.7 million cash (not
including the permitted dividend) and 3,126,903 shares of NYX stock. The $11.7 million cash distribution was treated as monetary consideration for which a realized gain was recognized in the first quarter of 2006.

APB No. 29 (as amended) provides guidance on exchanges of assets in a non-monetary transfer. Accounting for non-monetary assets acquired in a
substantially non-monetary exchange is at times based on cost or fair value of the assets relinquished and at times on the fair value of the assets received in the exchange. Based on the guidance under APB No. 29, the Company valued the shares
of NYX stock received in the NYSE/Archipelago merger at fair value, which was deemed to be the value of the shares on the first day trading commenced for NYX stock, or $67.00 per share. Based upon this interpretation, the Company realized a $130.1
million gain from the exchange of its NYSE memberships for 3.1 million shares of NYX stock, which includes the effect of a valuation allowance due to the restrictions on transfer applicable to the NYX stock.

Since the consummation of the NYSE/Archipelago merger, the Company has accounted for its investment in the NYX stock as corporate equities not readily
marketable at the estimated fair value of such restricted shares pursuant to the American Institute of Certified Public Accountants Audit and Accounting GuideBrokers and Dealers in Securities.At December 31, 2006, the NYSE closing
market price for the NYX stock was $97.20 per share as compared to the closing price of NYX stock on the merger consummation date which was $67.00. This resulted in the Companys recognition of an unrealized gain of $94.1 million for the year
ended December 31, 2006, which includes a valuation allowance due to the share restrictions and is included in net gain on NYX transaction in the Companys Consolidated Statement of Operations. The shares of NYX stock received in the
NYSE/Archipelago merger are subject to a three-year restriction on transfer. The restriction will be removed in equal one-third installments on each of March 7, 2007, 2008 and 2009, unless the restrictions are removed earlier by the NYSE Group
in its sole discretion.

The exercise prices for options to purchase an aggregate of 1,599,389 shares of common stock
exceeded the average market price of the Companys common stock for the year ended December 31, 2006. In addition, potential common shares relating to restricted stock and restricted stock units whose fair value was below the average
market price of the Companys common stock for the year ended December 31, 2006 totaled 727,774. Accordingly, the above calculations of diluted earnings per share for 2006 do not include the antidilutive effect of these stock based awards.
Potential common shares relating to options totaling 1,709,778 and 2,319,167 for the years ended December 31, 2005 and 2004, respectively, and to restricted stock and restricted stock units totaling 651,518 and 574,353 for the years ended
December 31, 2005 and 2004, respectively, were excluded from the diluted loss per share calculation for the years ended December 31, 2005 and 2004 because their effect was antidilutive.



|13. | EMPLOYEE INCENTIVE PLANS
|--- | ------------------------

Equity Incentive Plan

The Company sponsors one share-based employee incentive planthe LaBranche & Co Inc. Equity Incentive Plan (the
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. The fair value of
the restricted stock awards is determined by using the closing price of the Companys common stock on the respective dates on which the awards are granted. Grant date is determined to be the date the compensation committee of the Board of
Directors approves the grant. Compensation costs for grants awarded under the Plan recognized during the years ended December 31, 2006 and 2005 was approximately $4.4 million and $2.9 million, respectively. The tax benefit realized in the
Consolidated Statements of Operations for the Plan was approximately $1.9 million and $1.3 million for the years ended December 31, 2006 and 2005, respectively.

At December 31, 2006, unrecognized compensation cost related to the Companys non-vested stock option and restricted stock unit awards totaled $7.0 million. The cost of these non-vested awards is generally
expected to be recognized over a weighted-average period of approximately three years.

SFAS No. 123(R) generally requires share-based
awards granted to retirement-eligible employees to be expensed immediately. The Company did not grant any share-based awards prior to the adoption of SFAS 123(R) to retirement-eligible employees or those with non-substantive non-compete agreements.
In addition, no grants of any stock options or RSUs were changed or amended after the adoption of SFAS No. 123(R) to reflect retirement eligibility or non-compete agreements.

The total number of shares of the Companys common stock that may be issued under the Plan through fiscal 2009 may not exceed 7,687,500 shares, of
which 3,023,625 were available for grant under the Plan as of December 31, 2006.

Restricted Stock and Restricted Stock Units

The Company issued restricted stock units to employees under the Plan, primarily in connection with year-end compensation. All of the
restricted stock units (RSUs) outstanding as of December 31, 2006 and December 31, 2005 required future service as a condition to the delivery of the underlying shares of common stock. In all cases, delivery of the underlying
shares of common stock is conditioned on the grantees satisfying certain requirements outlined in the agreements. Generally, the restricted stock units become fully vested if the grantee's employment with the Company terminates by reason of
death or disability prior to vesting. The grantee forfeits the unvested portion of the restricted stock units upon the termination of employment for any reason other than death or disability. When delivering the underlying shares of stock to
employees, the Company generally issues new shares of common stock, as opposed to reissuing treasury shares.

The following table provides
information about grants of RS and RSUs:

Under SFAS No. 123(R), the Company is required to estimate forfeitures of RSUs for purposes
of determining the Company's share-based award expense. Applying SFAS No. 123(R) as of December 31, 2006, for purposes of determining share-based award expense, RSUs with respect to 1,428,169 shares of the Company's common stock were
expected to vest, with a weighted average price of $9.44 per share.

Stock Options

As of December 31, 2004, all stock options granted to employees were fully vested and exercisable. In general, all stock options expire on the tenth
anniversary of grant, although they may be subject to earlier termination or cancellation in certain circumstances under the Plan and the stock option agreement, such as death, disability or other termination of employment prior to the tenth
anniversary of grant. The dilutive effect of the Companys outstanding stock options is included in Weighted Average Common Shares OutstandingDiluted on the Condensed Consolidated Statement of Operations.

Senior Executive Bonus Plan

The Senior Executive
Bonus Plan, adopted in May 2003, is intended to provide for the payment to the Companys Chief Executive Officer and next four most highly compensated executive officers of bonuses which are exempt from the $1.0 million deduction limitation
imposed by Section 162(m) of the Internal Revenue Code of 1986, as amended. Bonuses are payable in cash and/or equity-based awards under the Companys EIP. For the year ended December 31, 2004, no bonuses were paid under this plan.
For the years ended December 31, 2006 and 2005, cash bonuses totaling approximately $2.6 and $3.3 million, respectively, were paid under this plan, and such amount is included in employee compensation and employee benefits in the Companys
Consolidated Statements of Operations.



|14. | RETIREMENT PLAN
|--- | ---------------

The Company has a defined
contribution retirement plan (the Plan) that is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

All employees are eligible to participate in the Plan after they have completed three months of service. Participants are entitled to contribute voluntarily in an amount equal to not less than 1% and not more than 60%

|17. | FINANCIAL INSTRUMENTS WITH CONCENTRATION OF CREDIT AND OFF-BALANCE SHEET RISK
|--- | -----------------------------------------------------------------------------

As specialists and market-makers on the NYSE, AMEX, NYBOT, PHLX and other exchanges, LaBranche & Co. LLC, LFS, LSP, LSPS and LSPE are engaged in various securities trading and lending activities. In
connection with their specialist activities, LaBranche & Co. LLC, LSP, LSPS and LSPE assume positions in stocks for which they are responsible. LaBranche & Co. LLC, LFS, LSP, LSPS and LSPE are exposed to credit risk associated with
the nonperformance of counterparties in fulfilling their contractual obligations pursuant to these securities transactions, and they are also exposed to market risk associated with the sale of securities sold but not yet purchased, which can be
directly impacted by volatile trading on the NYSE, AMEX and other exchanges. Additionally, in the event of nonperformance and unfavorable market price movements, LaBranche & Co. LLC, LFS, LSP, LSPS and LSPE may be required to purchase or
sell financial instruments, which may result in a loss.

The Company enters into collateralized financing agreements in which it extends
short-term credit to major financial institutions. The Company 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.

In addition, LFS, through the normal course of business, enters into various securities transactions as agent. The execution, settlement and financing of those transactions can result in off-balance sheet risk and
concentration of credit risk. LFS execution and clearing activities involve settlement and financing of various customer securities transactions on a cash or margin basis. These activities may expose LFS to off-balance sheet risk in the event
the customer or other broker is unable to fulfill its contractual obligations and LFS has to purchase or sell securities at a loss. For margin transactions, LFS may be exposed to significant off-balance sheet risk in the event margin requirements
are not sufficient to fully cover losses that customers may incur in their accounts.

LFS seeks to control the risks associated with
customer activities by requiring customers to maintain margin collateral in compliance with various regulatory and internal guidelines. LFS monitors margin levels daily and pursuant to such guidelines, requires customers to deposit additional
collateral or reduce positions when necessary.

LFS is engaged in various brokerage activities in which its counterparties primarily
include broker-dealers, banks and other financial institutions. LFS may be exposed to the risk of default, which depends on the creditworthiness of the counterparty. It is LFS policy to review, as necessary, the credit standing of each
counterparty with which it conducts business.

LSP and LSPS use derivative financial instruments, including exchange-traded options, ETFs
and domestic and foreign futures contracts, for trading purposes and to financially hedge other positions or transactions as part of their specialist and market-making businesses and overall risk management process. These financial instruments
subject LSP and LSPS to varying

|18. | RESTRUCTURING
|--- | -------------

During the fourth quarter of 2006,
the Company approved and implemented a restructuring plan, which was completed by January 2007, that was designed to improve the future operating position of the Company. The planned action included termination of employees whose services were no
longer deemed necessary due to increased automation with the introduction of the HYBRID market. The total costs incurred under this plan was $3.7 million, which was expensed in 2006. These amounts consisted of severance payments to terminated
employees and are included in restructuring costs on the statement of operations. Of the $3.7 million expensed, $1.2 was paid in the fourth quarter of 2006, and the remaining payable balance of $2.5 million was disbursed in January 2007. For 2006,
the restructuring expenses incurred by segment are as follows (000s omitted):

Contingencies

Specialist Trading Investigations. On March 30, 2004, LaBranche & Co. LLC and other NYSE specialist firms entered
into agreements with the SEC and NYSE to settle the SEC and NYSE investigations concerning alleged improper specialist trading practices by specialists on the NYSE. Pursuant to the settlement, LaBranche & Co. LLC consented, without
admitting or denying any wrongdoing, to an SEC order instituting administrative cease-and-desist proceedings, making findings, and imposing remedial sanctions and a cease-and-desist order. The SECs findings, neither admitted nor denied,
included violations by LaBranche & Co. LLC of Section 11(b) of the Exchange Act and Rule 11b-1 promulgated thereunder, NYSE Rules 104, 92, 123B, 401 and 342, and Section 15(b)(4)(E) of the Exchange Act. The
Section 15(b)(4)(E) finding includes a failure reasonably to supervise individual specialists who, the finding states, violated Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder with respect to transactions in six
particular stocks. Pursuant to the settlement, LaBranche & Co. LLC paid $41.6 million in restitution and $21.9 million in a civil money penalty, which the Company accrued for the year ended December 31, 2003, in connection with trades
that occurred during the years 1999 through 2003 and agreed to certain undertakings stated in the SECs order.

NYSE, civil and/or
criminal charges have been pursued against a number of individuals employed or formerly employed as specialists at the five largest NYSE specialist firms, including employees and former employees of LaBranche & Co. LLC.

plaintiffs: Anthony Johnson, Clyde Farmer, Edwin Walthall, Donald Stahl and City of Harper Woods Retirement System.

On June 7,
2004, plaintiffs filed a Consolidated Class Action Complaint. On July 12, 2004, plaintiffs filed a Corrected Consolidated Class Action Complaint. Plaintiffs allege that they represent a class consisting of persons and entities that purchased or
otherwise acquired the Companys common stock during the period beginning on August 19, 1999 and concluding on October 15, 2003. Plaintiffs allege that the Company, LaBranche & Co. LLC, and certain of the Companys
and/or LaBranche & Co. LLCs past or present officers and/or directors, including George M.L. LaBranche, IV, William J. Burke, III, James G. Gallagher, Alfred O. Hayward, Jr., Robert M. Murphy and Harvey S. Traison, violated
Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder and Section 20(a) of the Exchange Act by failing to disclose the alleged improper specialist trading that was the subject of the specialist trading investigations
described above. Plaintiffs also allege that Mr. Gallagher violated Section 20A of the Exchange Act and two other of the Companys past or present officers and/or directors, S. Lawrence Prendergast and
George E. Robb, Jr., also violated Section 20(a) of the Exchange Act. Plaintiffs seek unspecified money damages, attorneys fees and reimbursement of expenses.

On December 12, 2005, motions to dismiss were granted in part and denied in part. The court dismissed the Section 10(b) claims in their
entirety against Messrs. Burke, Gallagher and Traison, dismissed the Section 10(b) claims for the period August 19, 1999 through December 30, 2001 against Messrs. LaBranche, Murphy and Hayward, and dismissed the Section 20A claim
against Mr. Gallagher.

In re NYSE Specialists Securities Litigation. On or about October 16, 2003 through
December 16, 2003, four purported class action lawsuits were brought by persons or entities who purchased and/or sold shares of stocks of NYSE listed companies for which LaBranche & Co. LLC and any other NYSE specialist firm acted as
specialist, including Pirelli v. LaBranche & Co Inc., et al., No. 03 CV 8264, Marcus v. LaBranche & Co Inc., et al., No. 03 CV 8521, Empire v. LaBranche & Co Inc., et al., No. 03 CV 8935, and the California
Public Employees Retirement System (CalPERS) v. The New York Stock Exchange, Inc., et al., No. 03 CV 9968. On March 11, 2004, a fifth action asserting similar claims, Rosenbaum Partners, LP v. The New York Stock Exchange, Inc., et
al., No. 04 CV 2038, was filed in the United States District Court for the Southern District of New York by an individual plaintiff who does not allege to represent a class.

On May 27, 2004, the court consolidated these lawsuits under the caption In re NYSE Specialists Securities Litigation, No. CV 8264. The court named the
following lead plaintiffs: California Public Employees Retirement System (CalPERS) and Empire Programs, Inc.

On
September 15, 2004, plaintiffs filed a Consolidated Complaint for Violation of the Federal Securities Laws and Breach of Fiduciary Duty alleging that they represent a class consisting of all public investors who purchased and/or sold shares of
stock listed on the NYSE from October 17, 1998 to October 15, 2003. Plaintiffs allege that the Company, LaBranche & Co. LLC, Mr. LaBranche, and other NYSE specialist firms and their respective parents and affiliates violated
Section 10(b), Rule 10b-5 and Section 20(a) by failing to disclose the alleged improper specialist trading that was the subject of the specialist trading investigations described above, improperly profiting on purchases and/or sales of
NYSE-listed securities and breaching and/or aiding and abetting breaches of fiduciary duty. Plaintiffs also name the NYSE as a defendant. Plaintiffs seek unspecified money damages, restitution, forfeiture of fees, commissions and other compensation,
equitable and/or injunctive relief, including an accounting of and the imposition of a constructive trust and/or asset freeze on trading proceeds, and attorneys fees and reimbursement of expenses.

On December 12, 2005, defendants motion to dismiss was granted in part and denied in part. The court dismissed plaintiffs
Section 10(b) and Section 20(a) claims against all defendants for conduct that occurred before January 1, 1999 and dismissed plaintiffs breach of fiduciary duty claims against all defendants. The court also dismissed all claims
against the NYSE and certain claims against certain parents and affiliates of specialists other than LaBranche & Co. LLC.

On
February 2, 2006, plaintiffs filed an Amended Consolidated Complaint for Violation of the Federal Securities Laws and Breach of Fiduciary Duty, adding Robert A. Martin as a plaintiff. This complaint is otherwise identical to plaintiffs
Consolidated Complaint for Violation of the Federal Securities Laws and Breach of Fiduciary Duty.

On February 22, 2007, the court removed
Empire Programs, Inc. as co-lead plaintiff, leaving CalPERS as the sole lead plaintiff.

NASD/AMEX Notice of Disciplinary Action. On
December 15, 2004, LaBranche & Co. LLC received a notice from the NASD Amex Regulation Division stating a preliminary determination to seek disciplinary action against LaBranche & Co. LLC for violations of certain federal
securities laws and the Amex Constitution and Rules, including Sections 10(b), 9A and 17(a) of the Exchange Act, in connection with manual book freezes effected in one of LaBranche & Co. LLCs Amex specialist stocks during the period
March 8, 2004 through October 21, 2004. Prior to receiving this notice, the Company had determined that the individual specialist responsible for the book freezes failed to adhere to company policy and had terminated that employee.
The Company submitted a response to the staff in January 2005 of the NASD Amex Regulation Division setting forth the reasons why disciplinary action should not be brought against LaBranche & Co. LLC and the Company is cooperating with the
NASD Amex Regulation Division in this matter.

The Company believes that the claims asserted against the Company by the plaintiffs in the
pending proceedings described above are without merit, and the Company denies all allegations of wrongdoing. There can be no assurance, however, as to the outcome or timing of the resolution of these proceedings. The Company therefore is unable to
estimate the amount or

potential range of any loss that may arise out of these proceedings. The range of possible resolutions could include determinations and judgments against the
Company or settlements that could require substantial payments by the Company that could have a material adverse effect on the Companys financial condition, results of operations and cash flows.

In addition to the proceedings described above, the Company has been the target, from time to time, of various claims, lawsuits and regulatory actions
incidental to the ordinary course of the Companys business. While the ultimate outcome of those claims, lawsuits and regulatory actions which currently are pending cannot be predicted with certainty, the Company believes, based on its
understanding of the facts of these claims, proceedings and regulatory actions, that their ultimate resolution will not, in the aggregate, have a material adverse effect on the Companys financial condition, results of operations or cash flows.

Commitments

The
Company has entered into long-term non-cancelable operating lease agreements for certain office space and equipment, which expire at various dates through 2017. Certain lease agreements contain escalation clauses providing for increased rental
payments based on increases in maintenance charges and real estate taxes. Minimum future rental commitments under existing non-cancelable leases for office space and equipment are as follows:

NOTES TO CONDENSED FINANCIAL STATEMENTS



|1. | OVERVIEW
|-- | --------

The accompanying condensed financial
statements of LaBranche & Co Inc. (Parent Company Only) should be read in conjunction with the consolidated financial statements of LaBranche & Co Inc. and Subsidiaries and the notes thereto contained elsewhere in this filing.



|2. | BASIS OF PRESENTATION
|-- | ---------------------

Certain of the
Companys December 31, 2005 and 2004 balances on the condensed statements of operations have been reclassified to conform to the presentation in the current period in order to net interest expense (including margin interest expense)
against interest income to determine the Companys net revenues. This reclassification reflects a critical component of the Companys specialist and market-making activities. None of these 2005 and 2004 reclassifications affects the
Companys net income before provision for income taxes or net income applicable to common stockholders, as reported on previous 2005 and 2004 results.



|3. | TRANSACTIONS WITH SUBSIDIARIES
|-- | ------------------------------

LaBranche & Co Inc. has transactions with its consolidated subsidiaries determined on an agreed-upon basis.

LaBranche & Co Inc. received cash dividends from its consolidated subsidiaries totaling $152.0 million, $77.3 million and $86.0 million for the years ended December 31, 2006, 2005 and 2004, respectively.
