                               PROSPECTUS SUMMARY

    THE INFORMATION BELOW IS ONLY A SUMMARY OF MORE DETAILED INFORMATION
INCLUDED IN OTHER SECTIONS OF THIS PROSPECTUS. THE OTHER INFORMATION IS
IMPORTANT, SO PLEASE READ THIS ENTIRE PROSPECTUS CAREFULLY. UNLESS STATED
OTHERWISE, THE INFORMATION CONTAINED IN THIS PROSPECTUS ASSUMES THAT THE
UNDERWRITERS' OVER-ALLOTMENT OPTION TO PURCHASE 1,725,000 SHARES OF OUR COMMON
STOCK HAS NOT BEEN EXERCISED AND THAT WE HAVE COMPLETED THE REORGANIZATION OF
OUR FIRM FROM PARTNERSHIP TO CORPORATE FORM.

                              LABRANCHE & CO INC.

    Founded in 1924, we are one of the oldest and largest specialist firms on
the New York Stock Exchange. In 1998, the stocks for which we acted as
specialist accounted for approximately 14.2% of the dollar volume of common
stock traded on the NYSE, constituting one of the largest market shares among
specialist firms. As of June 30, 1999, we acted as specialist in 280 common
stock listings, including 47 of the S&P 500 and five of the 30 companies
comprising the Dow Jones Industrial Average. Our five Dow stocks are AT&T,
Chevron, Exxon, Merck and Minnesota Mining & Manufacturing.

    All trading of securities on the NYSE is conducted through an auction
process managed by the specialist for each security. The specialist is a
broker-dealer who is granted the franchise by the NYSE to conduct the auction in
particular stocks and is assigned the role to maintain a fair and orderly market
in its specialist stocks. As of June 30, 1999, there were 29 specialist units as
compared with 39 at December 31, 1994. The substantial majority of trades in
NYSE-listed stocks takes place on the floor of the NYSE and is handled by
specialist firms. Specialist firms generate revenues by executing trades, either
as agent or principal, in their specialist stocks.

    Our business has grown considerably during the past five years. The total
annual share volume on the NYSE of stocks for which we act as specialist has
increased from approximately 3.4 billion in 1994 to nearly 20.0 billion in 1998,
representing a compound annual growth rate of 55.4%. During the same period, our
annual revenues increased from $29.9 million to $126.4 million, representing a
compound annual growth rate of 43.4%. We have accomplished our growth both
internally and through selective acquisitions. Since the March 1997
implementation of a new NYSE allocation process which allows listing companies
to make the final selection of their specialist, we have added 42 new common
stock listings to our firm. In addition, we have acquired three specialist
operations since 1997, adding 128 new common stock listings to our firm.

    Our revenues are primarily driven by the volume of trading on the NYSE. The
NYSE is currently the largest securities market in the world. The market
capitalization of all U.S. shares listed on the NYSE at December 31, 1998 was
approximately $10.9 trillion, representing approximately 80% of the market
capitalization of all shares publicly traded on U.S. national markets. The
NYSE's average daily trading volume increased from 291.4 million shares in 1994,
to 673.6 million shares in 1998, representing a compound annual growth rate of
23.3%. We believe that this increase in NYSE trading volume is due to a number
of factors including:

    - an increase in the amount of funds invested in equity securities;

    - an increase in the number of NYSE-listed stocks; and

    - an increase in the use of computerized trading strategies.

    We believe that several changes under consideration by the NYSE, including
longer trading days and trading in decimals, if enacted, will likely contribute
to additional growth in NYSE trading volume.

                                       1
<PAGE>
    We believe our success is due to our:

       - leading position in the specialist market;

       - diverse and high quality specialist stocks;

       - strong market-making skills;

       - innovative customer-oriented services; and

       - recent acquisitions.

    Our strategies for growing our revenues and profits are to:

       - aggressively pursue new listings;

       - actively participate in the consolidation of the specialist industry by
         making selective acquisitions; and

       - increase our capital base and our access to capital.

    Our revenues in 1998 were $126.4 million on an actual basis and $137.9
million on a pro forma basis, while our net income for the same period was $2.7
million on an actual basis and $31.9 million on a pro forma basis. Our revenues
for the first six months of 1999 were $103.5 million on both an actual and pro
forma basis, while our net income for the same period was $6.3 million on an
actual basis and $27.7 million on a pro forma basis. Pro forma revenues and net
income give effect to (1) our July 1998 acquisition of substantially all the
assets of Fowler, Rosenau and Geary, LLC and (2) the reorganization of our firm
from partnership to corporate form and related transactions.

                    REORGANIZATION AND RELATED TRANSACTIONS

    LaBranche & Co Inc. is a newly formed holding corporation, and after giving
effect to a number of transactions to be effected concurrently with this
offering and a concurrent note offering, our assets will consist solely of our
ownership interests in our two subsidiaries, LaBranche & Co. and LaB Investing
Co. L.L.C. LaBranche & Co. is a limited partnership, and LaB Investing Co.
L.L.C. is the general partner of LaBranche & Co. The reorganization of our firm
from partnership to corporate form, as illustrated below, will be effected
through the transactions summarized below:

                                   [GRAPHIC]

    - The members of LaB Investing Co. L.L.C. have agreed, subject to the
      completion of this offering, to exchange their membership interests in LaB
      Investing Co. L.L.C. for an aggregate of 34,750,000 shares of our common
      stock. In addition, three members of LaB Investing Co. L.L.C. will receive
      an aggregate of $10.0 million in cash as part of the exchange. We thus
      will become the sole member of LaB Investing Co. L.L.C., and LaB Investing
      Co. L.L.C. will continue to be the general partner of LaBranche & Co.


    - The limited partners of LaBranche & Co., other than Mill Bridge, Inc.,
      have agreed, subject to the completion of this offering, to exchange their
      limited partnership interests in LaBranche & Co. for an aggregate of $68.1
      million in cash, 625,000 shares of our common stock and subordinated
      indebtedness of $350,000.


    - Mill Bridge, Inc., a subsidiary of Van der Moolen Holding NV, will receive
      $90.0 million from us in exchange for its limited partnership interest in
      LaBranche & Co., including $74.0 million in cash after this offering and
      our note offering and a subordinated note for $16.0 million. In addition,
      we will repay $5.0 million of subordinated debt to an affiliate of Van der
      Moolen upon the closing of this offering and our note offering.

    - As a result of the above transactions, we will become the sole limited
      partner of LaBranche & Co., which will continue to operate as a
      broker-dealer and a NYSE specialist firm.


    - We will grant (1) options to purchase an aggregate of 1,200,000 shares of
      our common stock to our executive officers and (2) restricted stock units
      for 1,059,000 shares of common stock to employees who are not managing
      directors, in each case under the Equity Incentive Plan.

Common stock offered........................  11,500,000 shares

Common stock to be outstanding after the
  offering..................................  46,875,000 shares

Use of proceeds.............................  The estimated net proceeds from this offering
                                              will be approximately $169.5 million. We intend
                                              to use the majority of the net proceeds for
                                              general corporate purposes to support the growth
                                              of our business, including working capital and
                                              future acquisitions. In addition, we will use
                                              approximately $60.1 million to redeem some of
                                              the limited partnership interests of our
                                              subsidiary, LaBranche & Co., as part of the
                                              reorganization of our firm from partnership to
                                              corporate form. There is no specific allocation
                                              for a substantial portion of the net proceeds,
                                              and there can be no assurance that management
                                              will be able to use the unallocated proceeds
                                              effectively to continue to grow our business.
                                              See the risk factor entitled "We may not
                                              effectively use the unallocated proceeds of this
                                              offering to continue to grow our business."

                 SUMMARY HISTORICAL CONSOLIDATED FINANCIAL DATA

    The summary historical consolidated financial data set forth below for the
years ended December 31, 1996, 1997 and 1998 have been derived from our
consolidated financial statements, which have been audited by Arthur Andersen
LLP, independent public accountants, and are included elsewhere in this
prospectus. The summary historical consolidated financial data set forth below
for the years ended December 31, 1994 and 1995 have been derived from our
consolidated financial statements, audited by Arthur Andersen LLP, independent
public accountants, which are not included elsewhere in this prospectus. The
summary historical financial data set forth below for the six months ended June
30, 1998 and 1999 have been derived from our unaudited consolidated financial
statements. In our opinion, such unaudited data include all adjustments
(consisting of only normal recurring adjustments) necessary for a fair
presentation of the information set forth therein. The results of operations for
the six months ended June 30, 1999 are not necessarily indicative of results to
be expected for any future period. The summary historical consolidated financial
data set forth below should be read in conjunction with the consolidated
financial statements and related notes thereto and with "Management's Discussion
and Analysis of Financial Condition and Results of Operations," which are

    Historically, we have operated as a partnership and have distributed all of
our income after unincorporated business taxes to our managing directors as
compensation and to our partners. Concurrently with this offering and our note
offering, we will reorganize our firm from partnership to corporate form and in
connection with the reorganization, will redeem limited partnership and
membership interests. As a corporation, we will include payments to managing
directors as part of compensation and benefits. Therefore, historical income
before managing directors' compensation, limited partners' interest in earnings
of subsidiary and unincorporated business taxes understates our expected
operating costs after this offering and our note offering. See "--Reorganization
and Related Transactions" and "--Summary Pro Forma Consolidated Financial Data."
As a partnership, we generally have not been subject to U.S. federal, state and
local income taxes, apart from unincorporated business taxes. As a consequence
of our reorganization to a corporation, we will be subject to U.S. federal,
state and local income taxes.

                 SUMMARY PRO FORMA CONSOLIDATED FINANCIAL DATA


    The pro forma consolidated statement of operations data set forth below for
the year ended December 31, 1998 and the six months ended June 30, 1999 gives
effect to (1) our July 1998 acquisition of substantially all of the assets of
Fowler, Rosenau & Geary, LLC and (2) the reorganization of our firm from
partnership to corporate form and the related transactions. The pro forma
consolidated statement of operations for the six months ended June 30, 1999 and
for the year ended December 31, 1998 presents our results as if the
reorganization and related transactions had occurred on January 1, 1998.
Additionally, the pro forma consolidated statement of operations for the year
ended December 31, 1998 presents our results as if the acquisition of Fowler,
Rosenau had occurred on January 1, 1998. The pro forma as adjusted consolidated
balance sheet data as of June 30, 1999 give effect to (1) the reorganization and
related transactions as if they occurred on June 30, 1999, (2) our note
offering, (3) the application of the net proceeds of our note offering, (4) the
sale by us of 11,500,000 shares of common stock in this offering at an assumed
initial offering price of $16.00 per share, after deducting the underwriting
discount and estimated offering expenses payable by us, and (5) the application
of the net proceeds from this offering.

                                  RISK FACTORS

    YOU SHOULD CONSIDER CAREFULLY THE FOLLOWING RISKS BEFORE YOU DECIDE TO BUY
OUR COMMON STOCK. THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY
ONES THAT OUR COMPANY FACES. ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY
KNOWN TO US MAY ALSO ADVERSELY IMPACT OUR BUSINESS OPERATIONS. IF ANY OF THE
FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS, FINANCIAL CONDITION AND OPERATING
RESULTS COULD BE ADVERSELY AFFECTED. IN SUCH CASE, THE TRADING PRICE OF OUR
COMMON STOCK COULD DECLINE, AND YOU MAY LOSE ALL OR PART OF THE MONEY YOU PAID
TO PURCHASE OUR COMMON STOCK.

    THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS BASED ON OUR CURRENT
EXPECTATIONS, ASSUMPTIONS, ESTIMATES AND PROJECTIONS ABOUT OUR COMPANY AND OUR
INDUSTRY. THESE FORWARD-LOOKING STATEMENTS INVOLVE RISKS AND UNCERTAINTIES. OUR
ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-
LOOKING STATEMENTS AS A RESULT OF VARIOUS FACTORS DESCRIBED IN THIS SECTION AND
ELSEWHERE IN THIS PROSPECTUS. WE UNDERTAKE NO OBLIGATION TO UPDATE ANY
FORWARD-LOOKING STATEMENTS FOR ANY REASON, EVEN IF NEW INFORMATION BECOMES
AVAILABLE OR OTHER EVENTS OCCUR IN THE FUTURE.

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

    We recently experienced a substantial increase in the revenues we earn from
our specialist activities. An adverse change affecting the economy or the
securities markets could result in a decline in market volume or liquidity. This
would result in lower revenues from our specialist activities. Our recent
increase in revenues was caused primarily by significant increases in the volume
of trading on the NYSE and favorable conditions in the securities markets. The
current favorable business environment will not continue indefinitely. For more
details about the factors which have contributed to increases in volume on the
NYSE, see "Business--Industry Background--Recent Trends in NYSE Trading and the
Specialist's Role."

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

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

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

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

    - increases in claims and litigation.

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


    Alternative trading systems could reduce the levels of trading of
NYSE-listed stocks executed through specialists. This, in turn, could have an
adverse effect on our revenues. Over the past few years, a number of alternative
trading systems have developed or emerged which may compete with specialists by
increasing trading in NYSE-listed stocks off the NYSE trading floor in
over-the-counter markets. In the future, similar new systems may continue to be
developed and placed in operation. For more information regarding trading off
the NYSE trading floor and alternative trading systems, see "Business--Industry
Background--Recent Trends in NYSE Trading and the Specialist's Role."

<PAGE>
COMPETITION FROM NASDAQ FOR NEW LISTINGS COULD ADVERSELY AFFECT NYSE TRADING
  VOLUME AND, IN TURN, REDUCE OUR REVENUES.

    Nasdaq continues to grow and gain in popularity, attracting companies which
might otherwise have listed on the NYSE. If more companies decide to be quoted
on Nasdaq as opposed to listing their stocks on the NYSE, or if companies choose
to delist using recently relaxed delisting procedures, trading volume on the
NYSE could be adversely affected. This, in turn, could adversely affect our
trading revenue. In recent years, many high technology companies have opted to
be quoted on Nasdaq, even though many of them would have qualified for NYSE
listing. In addition, the SEC recently approved a revision to NYSE Rule 500
which makes it easier for a company to delist its shares from the NYSE. The
original rule required supermajority shareholder approval before a listed
company could delist from the NYSE. Under the recently approved amendment of
Rule 500, a company can delist from the NYSE if it obtains the approval of a
majority of the company's board of directors and the company's audit committee.
The company would then provide its 35 largest shareholders with written notice
of the proposed delisting and allow a 20-40 day waiting period to elapse.


OUR QUARTERLY RESULTS MAY FLUCTUATE SIGNIFICANTLY AND THE MARKET PRICE OF OUR
  COMMON STOCK COULD DECREASE.



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



    - a decrease in trading volume on the NYSE;



    - volatility in the equity securities markets; and



    - changes in the value of our securities positions.



For example, in the third quarter of 1998, compared to the second quarter of
1998, we experienced a decline in revenues primarily due to a decline in our net
trading gains from principal transactions conducted as part of our specialist
activities. Our net trading gains from principal transactions decreased during
this period primarily because the price levels of many of our specialist stocks
declined.



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



    If our operating results fall below the expectations of securities analysts
and investors, the market price of our common stock could decrease.


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

    A majority of our specialist-related revenues are derived from trading by us
as principal. We also operate a proprietary trading desk separately from our
NYSE specialist operations, which represented 1.8% of our total revenues in
1998. We may incur trading losses relating to these activities since each
primarily involves the purchase, sale or short sale of securities for our own
account. In any period, we may incur trading losses in a significant number of
our specialist stocks for a variety of reasons, including price declines of our
specialist stocks, lack of trading volume in our specialist stocks and the
required performance of our specialist obligations. From time to time, we have
large position concentrations in securities of a single issuer or issuers
engaged in a specific industry. In general, because our inventory of securities
is marked to market on a daily basis, any downward price movement in these
securities will result in a reduction of our revenues and operating profits.

                                       9
<PAGE>
    Although we have adopted risk management policies, we cannot be sure that
these policies have been formulated properly to identify or limit our risks.
Even if these policies are formulated properly, we cannot be sure that we will
successfully implement these policies. As a result, we may not be able to manage
our risks successfully or avoid trading losses.

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

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

WE WILL INCUR A SUBSTANTIAL AMOUNT OF INDEBTEDNESS SIMULTANEOUSLY WITH THIS
  OFFERING, THE AMOUNT AND TERMS OF WHICH MAY ADVERSELY AFFECT OUR ABILITY TO
  GROW, COMPETE AND RESPOND TO CHANGING MARKETS.

    We will have a substantial amount of indebtedness after the consummation of
our note offering. Our indebtedness and the related covenant restrictions could
have important consequences to you, including the following:

    - our ability to obtain additional financing and to fund our operations and
      our growth strategy may be impaired;

    - our ability to use operating cash flow in other areas of our business will
      be limited because we will have to make principal and interest payments;

    - we may not be able to compete with others firms that are not as leveraged;
      and

    - our substantial degree of leverage and our covenant restrictions may limit
      our ability to adjust to changing market conditions, changes in our
      industry and economic downturns.

    We may also need to incur additional debt in the future for working capital
or to complete acquisitions, even though covenants in our existing debt
agreements and the indenture governing our notes may limit our ability to do so.
In addition, if we breach any of these covenants, we may default under our
indebtedness.

    LaBranche & Co. is a broker-dealer and a specialist regulated by the
Securities and Exchange Commission and the NYSE. Such regulations include strict
rules regarding capital requirements and approval requirements for withdrawal of
capital from, and in some cases, other distributions by, the broker-dealer.
These regulations could prevent us from obtaining funds necessary to satisfy our
obligations to pay interest on or repay our indebtedness, including our notes.
See "Business--Regulatory Matters" for a discussion of our net capital
requirements.

                                       10
<PAGE>

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



    Our business depends on the availability of adequate capital. We cannot be
sure that we will have sufficient capital in the future or that additional
financing will be available on a timely basis, or on terms favorable to us.
Historically, we have satisfied these needs with internally generated funds, our
bank credit facilities and the issuance of subordinated debt. We currently
anticipate that the net proceeds from this offering and our contemplated
indebtedness, together with our available cash resources and credit facilities,
will be sufficient to meet our anticipated working capital, regulatory capital
and capital expenditure requirements through the end of 2000.


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

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

    - support more rapid expansion;

    - acquire complementary businesses; or

    - respond to unanticipated capital requirements.

    We may be required to obtain this additional financing on short notice as a
result of rapid, unanticipated developments, such as a steep market decline. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity."

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

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

OUR MANAGEMENT INFORMATION SYSTEMS MAY FAIL AND INTERRUPT OUR BUSINESS.

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


    - hardware or software failure; or



    - power or telecommunications failure.


    Although we have established a back-up disaster recovery center in Hoboken,
New Jersey, it may not be effective in preventing an interruption of our
business.

                                       11
<PAGE>
WE DEPEND ON THE NYSE AND CLEARING AND DEPOSITORY INSTITUTIONS TO EFFECT TRADES
  AND THEIR FAILURE TO PERFORM COULD SUBJECT US TO LOSSES.

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

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

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

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

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

    Our future success depends on the continued service of key employees,
particularly George M.L. LaBranche, IV (Michael LaBranche), our chairman and
chief executive officer. The loss of the services of any of our key personnel or
the inability to identify, hire, train and retain other qualified personnel in
the future could have an adverse effect on our business, financial condition
and/or operating results. We have entered into employment agreements with Mr.
LaBranche and other key employees. We also maintain "key person" life insurance
policies on Mr. LaBranche and other key employees. Competition for key personnel
and other highly qualified management, trading, compliance and technical
personnel is intense. We cannot assure you that we will be able to attract new
or retain currently employed highly qualified personnel in the future. See
"Management--Employment Agreements and Noncompetition Agreements."

    In connection with this offering and the reorganization of our firm from
partnership to corporate form, our managing directors will receive substantial
amounts of our common stock in exchange for their current interests in LaB
Investing Co. L.L.C. Because the shares of common stock will be received in
exchange for membership interests, ownership of these shares will not be
dependent upon the continued employment of those managing directors. In
addition, employees who are not managing directors will receive grants of stock
options and restricted stock units. The steps we have taken to encourage the
continued service of these individuals after this offering, who include key
senior personnel in our specialist activities, may not be effective. For a
description of the compensation plan for our employees to be implemented after
this offering, see "Management--Executive Compensation" and "Incentive Awards to
Our Employees."

                                       12
<PAGE>
WE DEPEND SIGNIFICANTLY ON REVENUES FROM OUR SPECIALIST ACTIVITIES FOR A SMALL
  GROUP OF LISTED COMPANIES, AND THE LOSS OF ANY OF THEM COULD REDUCE OUR
  REVENUES.

    Historically, a small number of listed companies have accounted for a
significant portion of our revenues from our specialist trading activities. The
loss of any of these listed companies could have an adverse effect on our
revenues. For the years ended December 31, 1997 and 1998, transactions in our 10
most actively traded specialist stocks accounted for 35.0% and 39.0% of our
total revenues, respectively. For the six months ended June 30, 1999, our
revenues from transactions in our 10 most actively traded specialist stocks
accounted for approximately 36.0% of our total revenues. We cannot assure you
that we will be able to retain these or other listed companies. We can lose
these listed companies if they cease to be traded on the NYSE as a result of
being acquired or otherwise delisted. In addition, if the NYSE were to determine
that we have failed to fulfill our obligations as specialist for a listed
company, our registration as a specialist for that listed company could be
cancelled or suspended.


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


    We derive substantially all of our revenues from specialist activities. If
demand for our specialist services fails to grow, grows more slowly than we
currently anticipate, or declines, our revenues would be adversely affected. We
expect our specialist activities to continue to account for substantially all 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;

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

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


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


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

    We cannot be sure that we will be able to compete effectively with current
or future competitors. Our failure to compete effectively would have an adverse
effect on our profitability. We obtain all of our new listings on the NYSE by
going through an allocation process. Under 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 to intensify in the future. Some of our competitors may have significantly
greater financial and other resources than we have and may have greater name
recognition. These competitors may be able to respond more quickly to new or
evolving opportunities and listing company requirements. They may also be able
to undertake more extensive promotional activities to attract new listing
companies. In addition, the specialist industry has recently been consolidating.
The combined companies resulting from this consolidation may have a stronger
capital base. This trend has intensified the competition in our industry.
Finally, the NYSE retains the ability to name new specialist firms.

WE MAY HAVE DIFFICULTY SUCCESSFULLY MANAGING OUR GROWTH.

    Since 1994, we have experienced significant growth in our business
activities and the number of our employees. We cannot assure you that we will be
able to manage our growth successfully. Our inability to do so could have an
adverse effect on our business, financial condition and/or operating results.
The growth of our business has increased the demands upon our management and
operations and we expect it to continue to do so in the future. This growth has
required, and will continue to require, us to increase our investment in
management personnel, financial and management systems

                                       13
<PAGE>
and controls, and facilities. In the absence of continued revenue growth, the
costs associated with our expected growth would cause our operating margins to
decline from current levels. The scope of procedures for assuring compliance
with applicable rules and regulations has changed as the size and complexity of
our business has increased. In response, we have implemented formal compliance
procedures which are regularly updated. Our future operating results will depend
on our ability to continue:

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

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

    - to recruit, train, manage and retain our employees.


YEAR 2000 COMPLIANCE PROBLEMS COULD CAUSE OUR TRADING-RELATED COMMUNICATIONS AND
  DATA PROCESSING SYSTEMS TO FAIL, WHICH COULD RESULT IN LOSSES.


    We may discover Year 2000 compliance problems that will require substantial
revisions. If we fail to fix our trading-related communications or data
processing systems or to fix or replace third-party software, hardware or
services on a timely basis, we could suffer a loss in revenues and our business,
financial condition and/or operating results could be adversely affected.
Moreover, our failure to address adequately Year 2000 compliance issues in our
main trading-related, communications or data processing systems could result in
litigation which could be a costly and time-consuming process. In addition, we
cannot be sure that third-party software, hardware or services incorporated into
our computer systems will not need to be revised or replaced. This could be
time-consuming and expensive.

    In addition, we cannot assure you that the NYSE, trading counterparties,
governmental agencies, utility companies, third-party service providers,
including clearing agencies and depositories, and others outside our control,
particularly other broker-dealers, will be Year 2000 compliant. The failure by
any of these entities to be Year 2000 compliant could result in a systemic
failure beyond our control, including:

    - a loss or reduction in our trading volume;

    - limitations on our ability to effectively engage in specialist activities;
      or

    - prolonged telecommunications or electrical failure.

    The occurrence of any systemic failure, including those listed above, could
prevent us from engaging in specialist activities and could have an adverse
effect on our business, financial condition and/or operating results.

    We have made an assessment of the Year 2000 readiness of our trading-related
communications and data processing systems. For more information regarding our
Year 2000 readiness, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Year 2000."

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

    The securities industry is subject to extensive regulation under both
federal and state laws. In addition, the SEC, NYSE, other self-regulatory
organizations, commonly referred to as SROs, and state securities commissions
require strict compliance with their respective rules and regulations. Failure
to comply with any of these laws, rules or regulations could result in serious
adverse consequences. We and our officers and employees may be subject in the
future to claims arising from acts in contravention of these laws, rules and
regulations. An adverse ruling against us and/or our officers and other
employees as a result of any of these claims could result in us and/or our
officers and other

                                       14
<PAGE>
employees being required to pay a substantial fine or settlement. It could also
result in the suspension or revocation of our registration with the SEC as a
broker-dealer or our suspension or expulsion as a member of the NYSE. If this
occurred, we would be unable to operate our business.

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

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


WE CANNOT PREDICT THE EFFECT A PROPOSED PUBLIC OFFERING BY THE NYSE WOULD HAVE
  ON OUR BUSINESS.



    The NYSE has recently announced that it is considering offering shares of
its capital stock to the public. We are unable to predict what effect, if any,
such an offering would have on our business and the specialist industry.


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

    The SEC, the NYSE and various other regulatory agencies have stringent rules
with respect to the maintenance of minimum levels of capital by securities
brokers-dealers as well as specialist firms. Failure to maintain compliance with
required minimum capital levels may subject us to suspension or revocation of
registration by the SEC and suspension or expulsion as a member of the NYSE and
other regulatory bodies. If this occurred, we would be unable to operate our
business. In addition, a change in these capital rules, the imposition of new
capital rules or any unusually large requirement or charge against our
regulatory capital could limit any of our operations that require the intensive
use of capital. These rules could also restrict our ability to withdraw capital
from LaBranche & Co. Any limitation on our ability to withdraw capital from
LaBranche & Co. could limit our ability to receive distributions from LaBranche
& Co. and LaB Investing Co. L.L.C., which, in turn, could limit our ability to
pay cash dividends, repay debt and repurchase shares of our outstanding stock. A
substantial market decline, a significant operating loss or any unusually large
requirement or charge against regulatory capital could adversely affect our
ability to expand or even maintain our present levels of business, which could
have an adverse effect on our business, financial condition and/or operating
results. See "Business-- Regulatory Matters."

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

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

                                       15
<PAGE>
WE ARE SUBJECT TO RISK RELATING TO LITIGATION AND POTENTIAL SECURITIES LAWS
  LIABILITY.

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

COUNTERPARTIES MAY FAIL TO PAY US.

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

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


    Immediately following this offering, our managing directors will own
approximately 72.5% of our outstanding common stock. These stockholders have
entered into a stockholders' agreement under which they have agreed, among other
things, that their shares of our common stock will be voted, for as long as they
own their shares, as directed by a majority vote of Michael LaBranche, our
chairman and chief executive officer, James G. Gallagher and Alfred O. Hayward,
Jr., each an executive officer and director. Accordingly, these individuals will
have the ability to control all matters requiring approval by our stockholders.
These matters include the election and removal of directors and the approval of
any merger, consolidation or sale of all or substantially all of our assets. In
addition, they will be able to dictate the management of our business and
affairs. This concentration of ownership could have the effect of delaying,
deferring or preventing a change in control, a merger or consolidation, a
takeover or another business combination that might otherwise give you the
opportunity to realize a premium over the then-prevailing market price for your
shares of our common stock.



THE MARKET PRICE OF OUR COMMON STOCK MAY DECREASE BECAUSE AN ACTIVE AND
  SUSTAINED TRADING MARKET FOR OUR COMMON STOCK MAY NOT DEVELOP.


    Prior to this offering, there has been no public market for our common
stock. Although we will make application for listing our common stock on the
NYSE, there can be no assurance that an active trading market will be created or
sustained. Due to the absence of any prior public market for the shares of our
common stock, there can be no assurance that the initial public offering price
will correspond to the price at which the shares of common stock will trade in
the public market subsequent to the offering. The initial public offering price
will be determined by negotiations among ourselves and representatives of the
underwriters based on several factors and will not necessarily reflect the
market price of our common stock following the offering.

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

    If our stockholders sell substantial amounts of our common stock in the
public market following this offering, the market price of our common stock
could fall. Such sales also might make it more difficult for us to sell equity
securities in the future at a time and price that we deem appropriate. After
this offering, we will have outstanding 46,875,000 shares of common stock. In
connection with the

                                       16
<PAGE>
reorganization of our firm from partnership to corporate form, our managing
directors and limited partners who are exchanging their interests for 35,375,000
restricted shares of our common stock have contractually agreed that they will
not sell their common stock for various time periods after this offering. Under
these contractual restrictions, these restricted shares are eligible for sale in
the public market as follows:

    In addition:


    - each of our managing directors must retain 25% of his or her common stock,
      currently totaling 8,501,318 shares in the aggregate, for the duration of
      his or her employment; and


    - an employee may not sell shares of our common stock that are subject to a
      pledge agreement, unless the requirements of the pledge agreement are
      waived by us.

    Our directors, officers and stockholders have agreed that they will not
sell, directly or indirectly, any common stock without the prior written consent
of Salomon Smith Barney Inc. for a period of 180 days from the date of this
prospectus.

    We intend to file a Form S-8 registration statement under the Securities Act
to register       shares of common stock issuable under our Equity Incentive
Plan. The registration statement will become effective immediately on filing.
Shares covered by that registration statement are eligible for resale in the
public markets, subject to Rule 144 limitations applicable to affiliates.


WE MAY NOT EFFECTIVELY USE THE UNALLOCATED PROCEEDS OF THIS OFFERING TO CONTINUE
  TO GROW OUR BUSINESS.


    The principal purpose of this offering is to provide more permanent capital
to support the growth of our specialist business. There is no specific
allocation for a substantial portion of the net proceeds, and our management
retains the right to utilize the net proceeds as it determines, including to
pursue selective acquisitions of other specialist firms. There can be no
assurance that management will be able to use the proceeds to effectively
continue the growth of our business.

THE TANGIBLE BOOK VALUE OF THE COMMON STOCK WILL BE SUBSTANTIALLY LOWER THAN THE
  OFFERING PRICE.

    The initial public offering price will be substantially higher than the pro
forma tangible book value per share of our outstanding common stock. If you
purchase our common stock in this offering, the shares you buy will experience
an immediate and substantial dilution in tangible book value per share. The
shares of common stock owned by existing stockholders will receive a material
increase in the

tangible book value per share. The dilution to investors in this offering will
be approximately $14.12 per share. As a result, if we were to distribute our
tangible assets to our stockholders immediately following this offering,
purchasers of shares of common stock in this offering would receive less than
the amount they will have paid for such shares. See "Dilution."


EFFECTS OF ANTI-TAKEOVER PROVISIONS COULD ENABLE OUR BOARD OF DIRECTORS TO
  PREVENT OR DELAY A CHANGE OF CONTROL OF OUR COMPANY.



    Some of the provisions of our certificate of incorporation, our bylaws and
Delaware law could, together or separately:


    - discourage potential acquisition proposals;

    - delay or prevent a change in control; and

    - limit the price that investors might be willing to pay in the future for
      shares of our common stock.


    In particular, our board of directors may issue up to 10,000,000 shares of
preferred stock with rights and privileges that might be senior to our common
stock, without the consent of the holders of the common stock. Our certificate
of incorporation and bylaws will provide, among other things, that our board of
directors will be divided into three classes which will serve staggered three
year terms, that stockholders may not take actions by written consent and that
special meetings of stockholders may only be called by our board of directors or
our chairman. We are also subject to Section 203 of the Delaware General
Corporation Law which generally prohibits a Delaware corporation from engaging
in any of a broad range of business combinations with any interested stockholder
for a period of three years following the date on which the stockholder became
an interested stockholder.

                                    DILUTION

    The pro forma net tangible book value of LaBranche & Co Inc. as of June 30,
1999, was approximately $(81,575,000), or $(2.31) per share of common stock. Pro
forma net tangible book value per share is equal to the amount of tangible net
assets of LaBranche & Co Inc., less total liabilities, divided by the pro forma
number of shares of common stock outstanding as of June 30, 1999. Assuming the
sale by LaBranche & Co Inc. of the shares of common stock offered hereby
(assuming an initial public offering price of $16.00 per share) and the
application of the net proceeds from this offering, the pro forma net tangible
adjusted book value of LaBranche & Co Inc. at June 30, 1999 would have been
approximately $87,925,000 or $1.88 per share of common stock. This amount
represents an immediate increase in pro forma net tangible book value of $4.19
per share to existing stockholders and an immediate dilution in net tangible
book value of $14.12 per share to new investors in the common stock in this
offering. The following table illustrates this per share dilution:

                    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 PROSPECTUS. 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. OUR ACTUAL RESULTS COULD DIFFER
MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS A
RESULT OF CERTAIN FACTORS, AS MORE FULLY DESCRIBED IN THE "RISK FACTORS" SECTION
AND ELSEWHERE IN THIS PROSPECTUS. WE UNDERTAKE NO OBLIGATION TO UPDATE PUBLICLY
ANY FORWARD-LOOKING STATEMENTS FOR ANY REASON, EVEN IF NEW INFORMATION BECOMES
AVAILABLE OR OTHER EVENTS OCCUR IN THE FUTURE.

OVERVIEW

    Founded in 1924, we are one of the oldest and largest specialist firms on
the New York Stock Exchange. Our business has grown considerably during the past
five years. We have accomplished this growth both internally and through
selective acquisitions. Our revenues increased from $29.9 million in 1994 to
$126.4 million in 1998, representing a compound annual growth rate of 43.4%.
During the same period, we increased the number of our common stock listings
from 122 to 284.

    REVENUES

    Our revenues consist primarily of net gains earned from principal
transactions in securities for which we act as specialist, and commissions
revenue earned from specialist activities. Net gain on principal transactions
represents trading gains net of trading losses and transaction fees, and are
earned by us when we act as principal buying and selling our specialist stocks.
These revenues are primarily affected by changes in share volume and
fluctuations in price in our specialist stocks. Share volume for our specialist
stocks has historically been driven by general trends in NYSE trading volume, as
well as factors particularly affecting our listed companies, including increased
merger and acquisition activity, stock splits, greater frequency of company news
releases (i.e., earnings guidance and reports), heightened research analyst
coverage and investor sentiment. Commissions revenue consists of commissions we
earn when acting as agent to match buyers and sellers for limit orders executed
by us on behalf of brokers after a specified period of time; we do not earn
commissions when we match market orders. Commissions revenue is primarily
affected by share volume of the trades executed by us as agent. Other revenue
consists of proprietary trading revenue and short-term interest income. In 1998,
net gain on principal transactions represented 75.2% of our total revenues,
commissions revenue represented 21.0% of our total revenues, and other revenue
represented 3.8% of our total revenues. For the first six months of 1999, net
gain on principal transactions represented 76.0% of our total revenues,
commissions revenue represented 17.3% of our total revenues, and other revenue
represented 6.7% of our total revenues.

    EXPENSES

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

    Historically, a large portion of the compensation payments to our managing
directors has not been presented as part of operating expenses. The aggregate
amount of these compensation payments has generally approximated LaB Investing
Co. L.L.C.'s interest in the income of LaBranche & Co., before managing
directors' compensation. Generally, these payments of compensation have been
allocated among our managing directors based on their respective percentage
interests in the profits of LaB

                                       24
<PAGE>
Investing Co. L.L.C. As a corporation, we will include payments to managing
directors in employee compensation and benefits expense. Therefore, historical
income before managing directors' compensation, limited partners' interest in
earnings of subsidiary and unincorporated business taxes understates our
expected operating costs after this offering.

    REORGANIZATION


    Simultaneously with this offering, we will incur indebtedness of
approximately $116.4 million to redeem some limited partnership interests in
LaBranche & Co. and some membership interests in LaB Investing Co. L.L.C. and to
repay subordinated indebtedness. As a result of this increased indebtedness, our
interest expense following this offering will be higher than historical levels.



    The redemption of the limited partners' interests is accounted for as a step
acquisition under the purchase method of accounting. The excess of purchase
price over the limited partners' capital accounts of $131.3 million is allocated
to intangible assets. Accordingly, amortization of intangible assets is expected
to increase in the future.


    INCOME TAXES

    As a partnership, we have generally not been subject to U.S. federal, state
and local income taxes, apart from the 4% New York City unincorporated business
tax. As part of our restructuring to a corporation, we will be subject to U.S.
federal, state and local income taxes. For information on our pro forma
effective tax rate as a corporation, see the pro forma consolidated information
included elsewhere in this prospectus.

    ACQUISITIONS

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

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

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

SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO SIX MONTHS ENDED JUNE 30, 1998

    REVENUES

    Total revenues increased 98.5% to $103.5 million for the six months ended
June 30, 1999, from $52.1 million for the same period in 1998, principally due
to the increase in revenue from net gain on principal transactions. Net gain on
principal transactions increased 92.7% to $78.7 million for the six months ended
June 30, 1999, from $40.8 million for the same period in 1998. This increase was
primarily due to an increase in share volume of our specialist stocks traded on
the NYSE. This increase, in turn, was due primarily to the Fowler, Rosenau
acquisition, by which we became the specialist for 76 additional common stock
listings, and was due also to increased share volume as principal in our
existing specialist stocks traded on the NYSE. Our share volume as principal
increased

                                       26
<PAGE>
97.0% to 4.5 billion shares for the six months ended June 30, 1999, from 2.3
billion shares for the same period in 1998.

    Commissions revenue increased 71.8% to $17.9 million for the six months
ended June 30, 1999, from $10.4 million for the same period in 1998. This
increase was due to an increase in share volume in which we acted as agent. This
increase, in turn, was primarily due to the increase in the number of our common
stock listings due to the Fowler, Rosenau acquisition, and was also due to
increased share volume in our existing specialist stocks traded on the NYSE. The
share volume executed by us as agent in our specialist stocks increased 55.0% to
1.8 billion shares for the six months ended June 30, 1999, from 1.1 billion
shares for the same period in 1998.

    Other revenue increased 669.6% to $6.9 million for the six months ended June
30, 1999, from $902,000 for the same period in 1998. This increase was primarily

    Lease of exchange membership expense increased 50.0% to $4.2 million for the
six months ended June 30, 1999, from $2.8 million for the same period in 1998.
This increase was due to the increase in the number of leased memberships from
31 to 43, primarily resulting from the Fowler, Rosenau acquisition, and was also
due to an increase in the average annual leasing cost of the memberships from
approximately $180,000 to $192,000 per membership. As a percentage of total
revenues, lease of exchange memberships expense decreased to 4.0% for the six
months ended June 30, 1999, from 5.3% for the same period in 1998.

    Interest expense increased 46.9% to $2.2 million for the six months ended

million at June 30, 1999, from $48.1 million at June 30, 1998.

    Exchange, clearing and brokerage fees consist primarily of fees paid by us

and as agent, as well as a flat annual fee. Exchange, clearing and brokerage
fees expense increased 46.8% to $2.0 million for the six months ended June 30,

improvements. Occupancy expense increased 74.7% to $725,000 for the six months
ended June 30, 1999, from $415,000 for the same period in 1998. This increase

<PAGE>
    Communications expense consists primarily of data retrieval and information
services and telephone and data lines. Communications expense increased 24.5% to
$538,000 for the six months ended June 30, 1999, from $432,000 for the same
period in 1998. This increase was the result of additional telephone, data

payments made to Fowler, Rosenau in 1998 under a profit sharing arrangement for
trading in a specialist stock. This arrangement was terminated when we acquired
Fowler, Rosenau in July 1998.

    Income before managing directors' compensation, limited partners' interest

million for 1998, from $47.8 million for 1997. This increase was primarily due
to an increase in share volume. This increase, in turn, was primarily due to
increased share volume as principal in our existing specialist stocks traded on
the NYSE, and was also due to the increase in the number of our common stock
listings due to the Fowler, Rosenau acquisition. Our share volume as principal

1997.

LIQUIDITY

    We have financed our business primarily through partners' capital and the
issuance of subordinated indebtedness. As of June 30, 1999, we had $346.1
million in assets, $38.1 million of which consisted of cash and short-term
investments, which primarily consist of reverse repurchase agreements payable on
short notice. As of December 31, 1998, we had $272.2 million in assets, $25.8
million of which consisted of cash and short term-investments.

    During 1999, we increased and extended our line-of-credit with The Bank of
New York to $100.0 million. Amounts outstanding under The Bank of New York
credit facility would be secured by our inventory in our specialist stocks. To
date, we have not utilized this facility. The credit facility matures on June
23, 2000. In addition, we have outstanding letter of credit agreements with U.S.
Trust Company aggregating approximately $1.6 million, collateralized by a
Treasury bill with a face value of $1.5 million and a cash balance of
approximately $200,000.


    As of June 30, 1999, our subordinated debt totaled $51.2 million (excluding
subordinated liabilities related to contributed exchange memberships). Of this
amount, $35.0 million represented senior subordinated debt placed through
several note purchase agreements. Of this $35.0 million, $20.0 million matures
on September 15, 2002 and bears interest at an annual rate of 8.2%, payable on a
quarterly basis; and $15.0 million matures on June 3, 2008 and bears interest at
an annual rate of 7.7%, payable on a quarterly basis. These notes are senior to
all other subordinated notes. Subordinated debt totaling $16.2 million
represents junior subordinated debt placed with limited partners and their
family members, and employees of the firm. This debt has maturities ranging from
the second half of 1999 through 2000, and bears interest at an annual rate of
10.0%, payable on a quarterly basis. The agreements relating to the junior
subordinated debt generally have automatic rollover provisions which extend the
maturities for an additional year, unless the lender provides notice at least
seven months prior to maturity. Concurrently with this offering, we will repay
$5.0 million of the junior subordinated debt as part of the reorganization of
our firm from partnership to corporate form.


                                       31
<PAGE>

    Concurrently with this offering, we will pay $152.1 million to acquire some
limited partnership interests in LaBranche & Co. and some membership interests
in LaB Investing Co. L.L.C., as part of the reorganization of our firm from
partnership to corporate form. Additionally, the proceeds of our note offering
and the issuance of $16.4 million of subordinated indebtedness will be used to
acquire some limited partnership interests in LaBranche & Co.



    Under our note offering, we will issue $100.0 million aggregate principal
amount of senior notes. The notes will bear interest at a rate of   % annually
and mature in             , 2004. The indenture covering the notes will include
certain covenants that, among other things, limit our ability to:


    - borrow money;

    - pay dividends on our stock or purchase our stock;

    - make investments;

    - engage in transactions with stockholders and affiliates;

    - create liens on our assets; and

    - sell assets or engage in mergers and consolidations.


    We will issue a subordinated note in an aggregate principal amount of $16.0
million as partial payment for the acquisition of a limited partnership
interest. The note will be repayable as to $6.0 million on the first anniversary
of issuance, $5.0 million on the second anniversary of issuance and $5.0 million
on the third anniversary of issuance, and will bear interest at the annual rate
of   %. We will also enter into a $350,000 cash subordinated loan agreement,
bearing interest at an annual rate of   %, as payment for the acquisition of a
limited partnership interest. In addition, we will repay $1.1 million in
indebtedness owed in connection with our retirement plans, which amount has been
accrued in the historical consolidated statement of financial condition.


    As a broker-dealer, we are 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. We are required to maintain minimum net capital, as defined,
equivalent to the greater of $100,000 or 1/15 of 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 our total net capital to less than 150% of our required
minimum capital. Moreover, broker-dealers, including us, 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% 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 detrimental
to the financial integrity of the broker-dealer. At June 30, 1999, we had net
capital of $100.0 million, which was $96.8 million in excess of our required net
capital of $3.2 million.

    The NYSE generally requires members registered as specialists to establish
that they can meet, with their own net liquid assets, a minimum dollar amount
which is the greater of $1,000,000 or 25% of their position requirement. As of
December 31, 1998, due to the market share represented by our specialist book,
the NYSE mandated that, notwithstanding the general rule, we maintain minimum
net liquid assets of the greater of $90.0 million or 120% of the position
requirement, adjusted by the amount of the position requirement for any new
stock allocated to us as specialist. The position requirement is the ability to
assume positions in our specialist stocks, of 30,000 shares of each S&P 500
common stock, 22,500 shares in all other common stocks, 4,500 shares in each
convertible preferred stock and 1,800 shares in each nonconvertible preferred
stock for which we act as a specialist. "Net

                                       32
<PAGE>
liquid assets" for a specialist who also engages in transactions other than
specialist activities is based upon its excess net capital as determined in
accordance with SEC Rule 15c3-1. As of June 30, 1999, our NYSE minimum required
dollar amount of net liquid assets was $91.5 million compared to actual net
liquid assets of approximately $116.3 million.

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

    We currently anticipate that net proceeds from this offering, our note
offering and the additional contemplated indebtedness, together with our
available cash resources and credit facilities, will be sufficient to meet our
anticipated working capital, regulatory capital and capital expenditure
requirements through the end of 2000.

MARKET RISK

    A majority of our specialist related revenues are derived from trading by us
as principal. We also operate a proprietary trading desk separately from our
NYSE specialist operations, which represented 1.8% of our total revenues in
1998. These activities involve primarily the purchase, sale or short sale of
securities for our own account. These activities are subject to a number of
risks, including risks of price fluctuations and rapid changes in the liquidity
of markets. In any period, we may incur trading losses in our specialist stocks
for a variety of reasons, including price declines of our specialist stocks,
lack of trading volume in our specialist stocks and the performance of our
specialist obligations. From time to time, we have large position concentrations
in securities of a single issuer or issuers engaged in a specific industry. In
general, because our inventory of securities is marked to market on a daily
basis, any downward price movement in these securities will result in a
reduction of our revenues and operating profits.

    We have developed a risk management process which is intended to balance our
ability to profit from our specialist activities with our exposure to potential
losses. In addition, we have trading limits relating to our proprietary trading
desk. For a full description of our risk management procedures and the limits
placed on our proprietary trading desk, see "Business--Risk Management" and
"--Our Proprietary Trading."

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

YEAR 2000

    Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. These date code fields
will need to accept four digit entries to distinguish between 21(st) century
dates and 20(th) century dates. As a result, computer systems and/or software
used by many companies and governmental agencies, including computers involved
in the securities industry, may need to be upgraded to comply with such Year
2000 requirements. Otherwise, these systems could suffer system failure or
miscalculations that would disrupt normal business activities. Significant
uncertainty exists concerning the potential effects associated with the failure
to achieve compliance with the Year 2000 requirements.

    We have made an assessment of the Year 2000 readiness of our
trading-related, communications and data processing systems. We participated in
the Securities Industry Association "streetwide" testing during the period of
February through April 1999. We believe that our main trading-related and
clearing systems are currently Year 2000 compliant. In addition, the NYSE has
assured us that their information and communications systems are Year 2000
compliant. We require vendors of material

                                       33
<PAGE>
hardware and software components of our information technology systems to
provide oral assurances of their Year 2000 compliance. We intend to enforce
these assurances from third parties to the fullest extent permitted by law.

    We cannot be sure that we will not discover Year 2000 compliance problems
that will require substantial revisions. In addition, we cannot be sure that
third-party software, hardware or services incorporated into our computer
systems will not need to be revised or replaced. This could be time-consuming
and expensive. If we fail to fix our trading-related, communications or data
processing systems or to fix or replace third-party software, hardware or
services on a timely basis, our business, financial condition and/or operating
results could be adversely affected. Moreover, our failure to address Year 2000
compliance issues adequately in our main trading-related, communications or data
processing systems could result in litigation which could be a costly and
time-consuming process.

    In addition, we cannot assure you that the NYSE, trading counterparties,
governmental agencies, utility companies, third-party service providers,
including clearing houses and others outside our control, particularly other
broker-dealers, will be Year 2000 compliant. We believe that, in the worst case
scenario, the failure by any of these entities to be Year 2000 compliant would
induce a systemic failure beyond our control resulting in, among other things:

    - a loss or reduction in our trading volume;

    - limitations on our ability to effectively engage in specialist activities;
      or

    - prolonged telecommunications or electrical failure.

    The occurrence of any systemic failure, including those listed above, could
prevent us from engaging in specialist activities and could have an adverse
effect on our business, financial condition and/or operating results.

    We have devised a contingency plan in the event of a Year 2000 system
related failure. After the close of business on December 31, 1999, we will back
up our entire system creating a second backup system. Our staff will process
December 31, 1999 trades during the period between January 1, 2000 through the
open of trading on January 3, 2000, giving us 48 hours to resolve any potential
problems prior to the start of trading on January 3, 2000.

    The total cost of our Year 2000 project is currently estimated to be
approximately $150,000. Costs related to the project are expensed as incurred,
and we have incurred approximately $125,000 of such costs as of June 30, 1999.

                                    BUSINESS

OVERVIEW

    Founded in 1924, we are one of the oldest and largest specialist firms on
the New York Stock Exchange. As a NYSE specialist, our role is to maintain, as
far as practicable, a fair and orderly market in our specialist stocks. In doing
so, we provide a service to our listed companies, and to the brokers, traders
and their respective customers who trade in our specialist stocks. We believe
that, as a result of our commitment to providing high quality specialist
services, we have developed a strong reputation among our constituencies,
including investors, members of the Wall Street community and our listed
companies.

    Our business has grown considerably during the past five years. Our revenues
increased from approximately $29.9 million in 1994 to $126.4 million in 1998,
representing a compound annual growth rate of 43.4%. We have accomplished our
growth both internally and through selective acquisitions. For example, since
the NYSE implemented its new specialist allocation process in March 1997, we
were selected by 42 new listed companies, resulting from 66 listing interviews.
In addition we have acquired three specialist operations since 1997, adding 128
new common stock listings to our firm. During the past five years, we have also
increased the scope of our business, as illustrated by the following data
obtained from the NYSE:

    - the annual dollar volume on the NYSE of stocks for which we acted as
      specialist increased to $950.4 billion in 1998, as compared to $112.3
      billion in 1994. Based on these dollar volumes, we were the largest
      specialist firm in 1998 as compared to the sixth largest in 1994;

    - the annual share volume on the NYSE of stocks for which we act as
      specialist increased to 20.0 billion in 1998, as compared to 3.4 billion
      in 1994. Based on these share volumes, we were the second largest
      specialist firm in 1998 as compared to the fourth largest in 1994; and

    - the total number of our common stock listings increased to 280 as of June
      30, 1999, as compared to 122 as of December 31, 1994. Based on the number
      of our common stock listings, we were the third largest specialist firm as
      of both of these dates. In addition, we act as specialist for 78 other
      listed securities.

    Our listed companies include:

    - 47 of the S&P 500 companies; and

    - five of the 30 companies comprising the Dow Jones Industrial Average. Our
      five Dow stocks are AT&T, Chevron, Exxon, Merck and Minnesota Mining &
      Manufacturing.

INDUSTRY BACKGROUND

THE NYSE

    The NYSE is currently the largest securities market in the world. The market
capitalization of all U.S. shares listed on the NYSE increased from
approximately $4.4 trillion at December 31, 1994 to approximately $10.9 trillion
at December 31, 1998, representing a compound annual growth rate of 25.0%. The
number of companies listed on the NYSE increased from 2,570 at the end of 1994
to 3,114 at the end of 1998.

                                       35

    The NYSE's average daily trading volume increased from 91.2 million shares
in 1984 to 673.6 million shares in 1998, as illustrated by the following graph:

    Trading on the NYSE takes place through open bids to buy and open offers to
sell made by NYSE members, acting as principal or as agent for institutions or
individual investors. Buy and sell orders meet directly on the trading floor
through an auction process, and prices are determined by the interplay of supply
and demand in that auction. In order to buy and sell securities on the NYSE, a
person must first be accepted for membership in the NYSE. The number of
memberships, or seats, is presently limited to 1,366, and the price of a
membership depends on supply and demand. Based on recent transfers of
memberships, the market price of a membership on the NYSE is over $2.0 million.
To become a member, each prospective applicant must also pass an examination
covering NYSE rules and regulations.

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

THE SPECIALIST

    All trading of securities on the NYSE is conducted through an auction
process. The auction process for each security is managed by the specialist for
that security. The specialist is a broker-dealer who applies for and, if
accepted, is assigned the role to maintain a fair and orderly market in its
specialist stocks. The number of specialist units on the NYSE, many of which are
organized as private partnerships, has decreased from 39 at December 31, 1994 to
29 at June 30, 1999. Of these, the three largest specialist units as ranked by
their number of specialist stocks were responsible for approximately 41.0% of
the average daily trading volume (measured by dollar volume) in 1998.

                                       36
<PAGE>
    A specialist firm is granted the franchise by the NYSE in a particular stock
to conduct the auction in that security. Specialist firms conduct their auctions
at specific trading posts located on the floor of the NYSE. Because the
specialist firm runs the auction in its specialist stocks, it knows of all bids
and offers in those stocks and gathers orders to price its stocks appropriately.

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

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

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

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

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

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

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

RECENT TRENDS IN NYSE TRADING AND THE SPECIALIST'S ROLE

    Specialist firms generate revenues by executing trades, either as agent or
principal, in their specialist stocks. Accordingly, the specialist firms'
revenues are primarily driven by the volume of

                                       37
<PAGE>
trading on the NYSE. This volume has increased significantly in recent years.
The increase in trading volume has resulted from a number of factors, including:

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

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

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

    - an increase in NYSE-listed stocks due to:

       - IPOs and spin-offs;

       - transfers from Nasdaq and the American Stock Exchange; and

       - an increase in listings of foreign companies;

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

    - an increase in on-line trading;

    - trading in smaller price increments;

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

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

    These factors have, in turn, been influenced by a strong U.S. economy, low
interest rates and low levels of inflation. In addition, the NYSE is considering
the following changes:

    - longer trading days;

    - trading in decimals; and

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

These changes are being considered for implementation within the next 18 months.
We believe that, if instituted, these changes will likely contribute to
additional growth in NYSE trading volume.

    The majority of trades in NYSE-listed stocks take place through NYSE
specialist firms. In 1998, specialist firms handled approximately 84.2% of
trades in NYSE-listed stocks. Trades in NYSE-listed stocks are also generally
effected as follows:

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

    - NYSE members may trade NYSE stocks that were listed after April 26, 1979
      off the NYSE in the over-the-counter market. Approximately 70.0% of the
      NYSE-listed stocks may be traded by NYSE members over-the-counter; and

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

    Technological advances have contributed to the increased trading through
alternative trading systems (ATSs), such as electronic communications networks
(ECNs) and crossing systems. While the first ECN was created in 1969, most of
the others currently in operation were started in the past few years. These
systems electronically facilitate the matching of buy and sell orders that are
entered by their network members. If a match does not occur, some ATSs will
forward unfilled orders to other ATSs or to exchanges such as the NYSE. Some of
these networks also allow limited negotiation

                                       38
<PAGE>
between members to facilitate a match. These ATSs generally limit trades over
their systems to their members, who are typically large financial institutions,
well-capitalized traders or brokerage firms. Additionally, some ATSs are being
developed to facilitate trading by retail investors. In April 1999, the SEC
ruled that these networks are allowed, and in specified cases are required, to
register and become subject to regulation as stock exchanges. To date, only one
of these networks has applied to register as a stock exchange.

    The percentage of annual trading of listed stocks on the NYSE has ranged
from 82.1% to 84.2% for the past five years. It is unclear, however, how the
alternative trading methods and new technologies just described or that may be
developed will affect the percentage of trading in listed stocks conducted on
the NYSE. The NYSE has indicated that it is studying the possibility of
embracing electronic communications network technology to expand trading. ATSs
may be developed, organized and operated by large brokerage houses and
investment banks with greater capital, better access to technology and direct
access to investors. As a result, these parties may be well positioned to direct
trading to these networks. These alternative trading methods may account for a
growing percentage of the trading volume of NYSE listed stocks.

    The accelerating growth of trading volume and the increase in stock prices
on the NYSE in the 1990s has increased the demands upon specialists. In order to
fulfill their obligations, specialists are required to execute a greater number
of trades in a shorter period of time with greater price volatility. In
addition, specialists are called upon to take larger positions in their
specialist stocks. These factors have led to a consolidation of specialist units
in the past five years. The number of specialist units on the NYSE decreased
from 39 at December 31, 1994 to 29 at June 30, 1999. We believe that the
specialist market is becoming increasingly dominated by a number of large,
better-capitalized specialist firms which are able to provide an enhanced level
of service.

LABRANCHE'S COMPETITIVE POSITION

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

    - LEADING POSITION IN THE SPECIALIST MARKET. We have a long-standing
      reputation as one of the leading specialist firms on the NYSE. Founded in
      1924, we have successfully grown our business and improved our services
      through widely varying market conditions. As of December 31, 1998:

       - trading in the stocks for which we acted as specialist during 1998
         accounted for 14.2% of the dollar volume on the NYSE. Based on this
         percentage, we were the largest specialist firm on the NYSE; and

       - trading in the stocks for which we acted as specialist during 1998
         accounted for 12.7% of the share volume on the NYSE. Based on this
         percentage, we were the second largest specialist firm on the NYSE.

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

    - STRONG MARKET-MAKING SKILLS. We utilize our strong market-making skills to
      actively trade as principal in our specialist stocks. We believe that we
      significantly improve liquidity in our specialist stocks, particularly
      during periods of market volatility. In 1998, approximately 30.4% of our
      trades were as principal as compared to an average of approximately 25.3%
      for all NYSE specialists.

                                       39
<PAGE>
    - INNOVATIVE CUSTOMER-ORIENTED SERVICES. We are committed to providing our
      listed companies a high level of service, in addition to our specialist
      functions on the trading floor. We provide our listed companies with
      detailed reports on the trading activity of their stocks. We also maintain
      frequent contact with a majority of our listed companies to discuss the
      trading in their stock. In addition, we were the first specialist firm to:

       - host an annual listed company conference;

       - publish a company newsletter; and

       - commission customer satisfaction surveys from our listed companies.

    - RECENT ACQUISITIONS. Since 1997, we have acquired the following three
      specialist operations, solidifying our position as one of the leading NYSE
      specialist firms:

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

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

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

    We have effectively employed our capital resources and skilled personnel to
    maximize the synergies created through consolidation. In doing so, we have
    succeeded in growing each of these acquired operations and enhancing their
    profitability.

LABRANCHE GROWTH STRATEGY

    Our objective is to continue the growth in our revenues and profits by
pursuing the following strategies:

    - AGGRESSIVELY PURSUE NEW LISTINGS. We have been and will continue to be
      aggressive in positioning ourselves in the NYSE allocation process.
      Between March 1997, when the NYSE adopted the new allocation procedure,
      and June 30, 1999, we participated in 66 selection pools for listed
      companies and were chosen by management of the listed companies in 42 of
      them. Recently, we were selected as specialist by Pepsi Bottling Group and
      Fox Entertainment, as these companies completed two of the six largest
      initial public offerings in the United States measured in dollars. In
      addition, Viacom chose us as specialist in 1999 when it transferred its
      listing to the NYSE, the largest transfer to the NYSE measured by market
      capitalization.

    - ACTIVELY PARTICIPATE IN THE CONSOLIDATION OF THE SPECIALIST INDUSTRY
      THROUGH SELECTIVE ACQUISITIONS. We intend to take advantage of the
      consolidation trend in the specialist industry by selectively pursuing
      acquisitions of other specialist operations. Largely due to our three
      recent acquisitions, we have more than doubled the number of our common
      stock listings from 122 at December 31, 1994 to 280 at June 30, 1999. We
      gained valuable experience through these transactions by effectively
      integrating the operations of other specialist firms with those of our
      own. We believe this experience will help us to:

       - identify and attract acquisition candidates; and

       - successfully integrate operations we may acquire.

        In addition, we believe that the ability to offer our publicly traded
    common stock as part of the purchase price for acquisitions will further
    help us in attracting acquisition candidates.


    - INCREASE OUR CAPITAL BASE AND EXPAND ACCESS TO CAPITAL. As a result of
      this offering and our note offering, we will have a more permanent capital
      base. We intend to proceed to strengthen our capital base to meet the
      increasing demands imposed by the current marketplace. For example, after
      this offering and our note offering, our working capital will increase
      from $123.7 million to $233.1 million. In selecting a specialist firm,
      listed companies often focus on the capital resources of the specialist,
      especially more recently as trading volumes have increased. We


                                       40
<PAGE>
      believe that a more permanent and stronger capital base will help us to
      continue our active capital utilization, thereby enhancing our reputation
      as an active specialist and helping us attract more new listings.

RECENT ACQUISITIONS

    In July 1998, we acquired substantially all the assets of Fowler, Rosenau &
Geary, LLC, including its right to act as a specialist on the NYSE. In
connection with the acquisition, the inactive members of Fowler, Rosenau were
admitted to LaBranche & Co. as limited partners and the active members of
Fowler, Rosenau became members of LaB Investing Co. L.L.C. The former members of
Fowler, Rosenau acquired an aggregate interest in LaBranche's future profits
equal to 22.4% at that time. In connection with this acquisition and with the
approval of the NYSE, we became the specialist firm for an additional 76 common
stock listings, including Chevron, Merck, Minnesota Mining & Minerals and
Schlumberger.

    In August 1997, we admitted Ernst & Company as a limited partner in
connection with our acquisition of the specialist operations of Ernst. At that
time, we also acquired the specialist operations conducted by individual
specialists at the firms of Homans and Ware & Keelips. In connection with these
transactions, we also hired as specialists, and admitted as members of LaB
Investing Co. L.L.C, several individuals who had been employed as specialists by
Ernst, Homans and Ware & Keelips. At the time of its admission as a limited
partner, Ernst acquired an interest in LaBranche & Co.'s future profits equal to
7.2% at that time. In connection with our acquisition of these specialist
operations and with the approval of the NYSE, we became the specialist firm for
an additional 33 common stock listings, including Exxon and Compaq.

    In July 1997, Thomas Shanley, James Stack and Mark Soltz, formerly
specialists on behalf of Stern Bros., LLC, were admitted as new members of LaB
Investing Co. L.L.C. In connection with their admission as members, Messrs.
Shanley, Stack and Soltz contributed capital to LaB Investing Co. L.L.C. which
was, in turn, contributed to LaBranche & Co. In connection with this acquisition
and with the approval of the NYSE, we became the specialist firm for an
additional 19 common stock listings.

OPERATIONS

NYSE RULES GOVERNING OUR SPECIALIST ACTIVITIES

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

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

    A specialist must make firm and continuous two-sided quotations that are
timely and that accurately reflect market conditions. In making these
quotations, the specialist's transactions are

                                       41
<PAGE>
calculated to contribute to the maintenance of price continuity with reasonable
depth. Following is an illustration of how a specialist acts as principal to
maintain price continuity:

        The most recent sale in a listed stock was $50, the best public bid (to
    buy) on the specialist's book is $49 3/4, and the best public offer (to
    sell) on the book is $50 1/4. A broker who wants to buy 100 shares at the
    market in this instance without a specialist would purchase at $50 1/4, the
    offer price. Similarly, a broker seeking to sell 100 shares without a
    specialist would receive $49 3/4, the bid price. The specialist, who is
    expected to provide reasonable price continuity, in this case might narrow
    the quote spread by offering or bidding for stock for its own account. In
    this instance, the broker who wants to buy 100 shares might buy at $50 1/16
    from the specialist, as opposed to buying the same amount of shares from the
    best offer of $50 1/4, thereby offering price improvement to the customer.
    In the next trade, a broker willing to sell 100 shares might sell to the
    specialist at $50, as opposed to selling to the best available bid of
    $49 3/4, again achieving price improvement for the customer.

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

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

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

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

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

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

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

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

RISK MANAGEMENT

    Because our specialist activities expose our capital to significant risks,
managing these risks is a constant priority for us. Our central role in the
auction process helps us to reduce risks by enabling us

                                       42
<PAGE>
to incorporate up-to-date market information in the management of our inventory,
subject to our specialist obligations. In addition, we have developed a risk
management process which is designed to balance our ability to profit from our
specialist activities with our exposure to potential losses. Our risk management
process includes as participants our executive operating committee, our floor
management committee, our floor team captains and our specialists. These
parties' roles are described as follows:

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

    FLOOR MANAGEMENT COMMITTEE.  Our floor management committee is composed of
Messrs. Flaherty, Hayward, Naughton, Gallagher and Pickett. This committee is
responsible for formulating and overseeing our overall risk management policies
and risk guidelines for each of our specialist stocks. In arriving at these
policies and guidelines, our floor management committee considers the advice and
input of our floor team captains. Our floor management committee meets with all
floor team captains no less than once a month to review and, if necessary,
revise the risk management policies for our company as a whole and/or for
particular specialist stocks. In addition, a member of our floor management
committee is always available on the trading floor to review and assist with any
unusual situations reported by a captain. Our floor management committee reports
to our executive operating committee about each of these situations.

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

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

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

    - our aggregate long and short positions;

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

    - our overall position in a particular stock;

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

    - average position size.

                                       43

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

LISTED COMPANY SERVICES

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

    - daily reports on the trading results of their stock;

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

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

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

NYSE MEMBERSHIPS

    NYSE memberships are granted only to individuals, and each individual
specialist must own or lease an NYSE membership. We have 48 specialists, each of
whom owns or leases a membership under the following arrangements:

    - 10 memberships are owned directly by 10 of our specialists;

    - four are owned by specialists and were financed by us, or by Fowler,
      Rosenau prior to the Fowler, Rosenau acquisition; and

    - 34 are leased by 34 of our specialists from other individual members, and
      we pay and guarantee the lease payments.

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

    As a self-clearing broker-dealer, we have made significant investments in
our trade processing systems. Our use of and dependence on technology have
allowed us to maintain our significant growth over the past several years. In
addition to using consultants who primarily service the specialist industry, we
have an in-house information technology staff. We currently clear an average of
33,000 principal trades per day. We do not clear trades for third parties. Our
information systems send and receive data from the NYSE through a dedicated data
feed.

    Our systems enable us to monitor, on a real-time basis, our profits and
losses along with our trading positions. The NYSE supplies us with specialist
position reporting system terminals both on the trading floor and in our
offices. These terminals allow us to monitor our trading profits and losses as
well as our positions. We have also developed software that allows us to monitor
these items in the event that the NYSE-provided systems fail.

                                       44
<PAGE>
    We have established a back-up disaster recovery center in Hoboken, NJ in the
event of a local disaster. The back-up system operates as a mirror image of our
primary computer system in New York City as we have a direct connection between
the two sites which we utilize to back-up all data on an hourly basis. On a
regular basis, we test both systems to assure that they are fully operational.

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

    Our information technology staff has developed software which enables our
corporate relations staff and our specialists to share information with each
other regarding upcoming company and industry conferences. In addition, we
monitor each of our specialist stocks intra-day to see if there are any
significant price and/or volume variances of which we should alert the listed
company. This has proven to be a valuable customer service tool.

OUR PROPRIETARY TRADING


    In 1995, we initiated a proprietary trading program, seeking to leverage our
trading and market experience. Our strategy is short-term oriented, and most of
our positions are intra-day and not held overnight. Four of our traders focus
primarily on stocks listed on the NYSE. A fifth trader focuses entirely on
listed futures and options on both United States Treasury obligations and
Eurodollars. In 1998, we derived less than 2.0% of our revenues from our
proprietary trading and we have averaged less than 3.0% over the past three
fiscal years; in the first six months of 1999, we derived approximately 4.7% of
our revenues from our proprietary trading. Our proprietary trading desk utilizes
a Windows NT based trade reporting system which captures all trades executed by
the trading desk and marks all positions to market. We are not permitted to
trade in stocks for which we act as specialist.


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

    - for 1999, we have limited our capital commitment for our proprietary
      trading to an aggregate maximum of $22.0 million per day and overnight
      positions of up to $13.5 million per day;

    - each of our proprietary traders have specific trading limits, which may
      not be exceeded without the approval of executive management. Our most
      experienced trader may invest up to $12.0 million per day and may hold
      overnight positions up to $7.5 million. Each of our other traders have
      daily investment limits of $5.0 million or less and overnight investment
      limits of $3.0 million or less, depending on their experience;

    - the positions of our futures and options traders are monitored by an
      in-house model that measures potential intra-day risk as well as actual
      dollar exposure; and

    - one of our managing directors who is not involved in our proprietary
      trading program serves as the risk manager for that program. He oversees
      all of our proprietary trading and has the authority to instruct the
      proprietary trading desk to liquidate positions or otherwise reduce risk.
      He reports directly to Michael LaBranche, our chief executive officer.

SPECIALIST COMPANIES

    As of June 30, 1999, we acted as specialist for 280 common stocks listed on
the NYSE. Our listed companies operate in a variety of industries including
financial services, media, oil and gas, retail, technology and
telecommunications. They ranged in market capitalization from some of the
smallest on the NYSE to some of its largest and well-known corporations. We also
represent 44 foreign listings on the NYSE. The following is a list of our top 50

cover of this prospectus.

MARKETING

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

REGULATORY MATTERS

GENERAL

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

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

    As a NYSE specialist firm, we are under constant review by the NYSE on all
aspects of our operations and financial condition. As part of the price
discovery mechanism implemented by the NYSE, every specialist transaction is
published immediately on the tape and is broadcast worldwide. The NYSE also
employs sophisticated monitoring and stringent rules approved by the SEC. The
NYSE's Market Surveillance Division examines specialists' trading in all stocks,
every trading day, including specialists' decisions to trade or to not trade as
principal.

NET CAPITAL REQUIREMENTS

    As a broker-dealer, we are subject to SEC Rule 15c3-1, which requires
minimum net regulatory capital. We are required to maintain minimum net capital,
as defined, equivalent to the greater of $100,000 or 1/15 of our aggregate
indebtedness, as defined. At June 30, 1999, our net capital, as defined by the
SEC, was approximately $100.0 million and exceeded minimum requirements by
approximately $96.8 million.

    The NYSE also requires members registered as specialists to establish that
they can meet, with their own net liquid assets, a minimum dollar amount which
is the greater of $1,000,000 or 25% of their position requirement. As of
December 31, 1998, due to the market share represented by our specialist book,
the NYSE mandated that, notwithstanding the general rule, we maintain minimum
net liquid assets of the greater of $90.0 million, adjusted by the amount of the
position requirement for any new stock allocated to us as specialist or 120% of
the position requirement. Our position requirement is the ability to assume
positions in stock in which we are registered, of 30,000 shares of each S&P 500
common stock, 22,500 shares in all other common stocks, 4,500 shares in each
convertible preferred

                                       47
<PAGE>
stock and 1,800 shares in each nonconvertible preferred stock in which we are a
specialist. "Net liquid assets" for a specialist firm that also engages in
transactions other than specialist activities is based upon its excess net
capital as determined in accordance with SEC Rule 15c3-1. As of June 30, 1999,
our NYSE minimum required dollar amount of net liquid assets was $91.5 million
compared to actual net liquid assets of approximately $116.3 million.

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

COMPETITION

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

    - 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 activities in their stocks.

    The following is a list of the top ten specialist units as of June 30, 1999,
based on their number of common stock listings:

    - Spear, Leeds & Kellogg

    - Fleet Specialists, Inc.

    - LaBranche & Co.

    - Wagner, Stott, Mercator LLC

    - Robb Peck McCooey Specialist Corp.

    - Bear/Hunter Specialists, LLC

    - Henderson Bros., Inc.

    - CMJ Partners LLC

    - MJ Meehan & Co., LLC

    - Fagenson & Co.

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

                                       48
<PAGE>
    NYSE listed stocks may be traded:

    - by NYSE members over-the-counter as long as the stocks were listed after
      April 26, 1979. Approximately 70.0% of the NYSE-listed stocks may be
      traded by NYSE members over-the-counter; and

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

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

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

EMPLOYEES

    As of June 30, 1999, we had 161 full-time employees, including 36 managing
directors, with:

    - 48 specialists, including 34 managing directors;

    - five traders in our proprietary trading department;

    - 85 trading assistants;

    - five Corporate Relations Department employees; and

    - 18 management, administration and finance staff, including two managing
      directors.

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

    Following our reorganization and the completion of this offering and our
note offering, three of our managing directors will retire from our firm.

PROPERTIES

    Currently, our main offices are located at One Exchange Plaza, New York, New
York. We lease approximately 23,500 square feet at this location. In 1999, our
lease payment will total $684,000. This lease expires in 2008. We also lease two
trading posts on the floor of the NYSE.

LEGAL PROCEEDINGS

    We are not a party to any legal proceedings.

BOARD COMMITTEES

    The audit committee of our board of directors will be established as soon as
practicable following the closing of this offering and our note offering and
will review, act on and report to our board of directors with respect to various
auditing and accounting matters, including the recommendation of our

                                       50
<PAGE>
auditors, the scope of our annual audits, fees to be paid to our auditors, the
performance of our independent auditors and our accounting practices. The audit
committee will be comprised solely of independent directors.


    The compensation committee of our board of directors will be established as
soon as practicable after the closing of this offering and our note offering and
will recommend, review and oversee salaries, bonuses, benefits and equity
incentives for our employees, consultants and directors. The compensation
committee will also administer our incentive compensation plans. The
compensation committee will be comprised of a majority of independent directors.


DIRECTOR COMPENSATION


    We intend to elect two non-employee directors as soon as practicable after
the completion of this offering and our note offering. It is anticipated that
non-employee directors will receive an annual retainer, attendance fees for
board and/or committee meetings plus options to purchase our common stock. Our
employee directors will not receive any additional compensation for serving on
our board or any committee of our board.


EXECUTIVE COMPENSATION

    Historically, our managing directors have all been members of LaB Investing
Co. L.L.C., the general partner of LaBranche & Co. The aggregate amount of
compensation received by all our managing directors generally approximated LaB
Investing Co. L.L.C.'s interest in LaBranche & Co.'s income before managing
directors' compensation. These payments of compensation have been allocated
among our managing directors based on the managing directors' respective
percentage interests in the profits of LaB Investing Co. L.L.C. Following this
offering and our note offering, we will conduct business in corporate form. As a
result, we believe that historical data does not provide a meaningful basis for
evaluating anticipated executive compensation following this offering and our
note offering.


    The following table sets forth the annual salary we intend to pay during
fiscal 1999 to our Chief Executive Officer and our four other executive officers
named under "--Our Executive Officers and Directors" (the "Named Executive
Officers") who acted as executive officers during fiscal 1998. The Named
Executive Officers will also be entitled to participate in our Annual Incentive
Plan. Under this plan, a compensation pool of up to 30% of our pre-tax income
will be set aside for our managing directors and other employees. The amounts
payable under the Annual Incentive Plan to the Named Executive Officers will be
dependent on our operating results and upon the overall performance of the Named
Executive Officers, as determined by the compensation committee of our board of
directors. In addition, the Named Executive Officers will be entitled to
participate in our Equity Incentive Plan. Our Annual Incentive Plan and Equity
Incentive Plan are described below under "Incentive Awards to Our Employees."

              EMPLOYMENT AGREEMENTS AND NONCOMPETITION AGREEMENTS

    As part of the reorganization of our firm from partnership to corporate
form, our managing directors, all of whom are members of LaB Investing Co.
L.L.C., will exchange their membership interests in LaB Investing Co. L.L.C. for
shares of our common stock. We have entered into employment agreements with each
member who will continue as a managing director after this offering and pledge
agreements and agreements regarding noncompetition and other covenants with all
members, whether or not they continue to be employed with us following this
offering, including, in both cases, each managing director who is a member of
our board of directors or is an executive officer. We have also entered into an
employment agreement and noncompetition agreement with our Executive Vice
President, Finance. The material terms of the employment, noncompetition and
pledge agreements are described below. You should refer to the exhibits that are
a part of the registration statement for copies of the forms of these
agreements. See "Available Information."

THE EMPLOYMENT AGREEMENTS

    Each employment agreement, other than the employment agreement with our
Executive Vice President, Finance, has an initial term of three to five years,
requires the managing director to devote his or her entire working time to our
business and affairs and is terminable on 90 days' notice by either party. The
employment agreement with our Executive Vice President, Finance has an initial
term of one year, requires him to devote his time as is reasonably necessary for
him to perform his duties and responsibilities and is terminable on 30 days'
notice by either party.

THE NONCOMPETITION AGREEMENTS

    Each noncompetition agreement contains the following provisions:

    CONFIDENTIALITY.  Each managing director and each executive officer is
required to protect and use "confidential information" in accordance with the
restrictions which we place on its use and disclosure.


    NONCOMPETITION.  During employment and until the later of 12 months
following termination of employment with us or the fifth anniversary of this
offering, a managing director or executive officer may not:


    - form, or acquire a 5% or greater ownership, voting or profit participation
      interest in, any competitive enterprise; or

    - associate with any competitive enterprise and in connection with such
      association engage in, or directly or indirectly manage or supervise
      personnel engaged in, any business activity that is related to his or her
      activities with us.

                                       52
<PAGE>

For this purpose, a "competitive enterprise" is any business enterprise that
engages in activity, or owns or controls a significant interest in an entity
that engages in activity that competes, directly or indirectly, with any
activity in which we are engaged. These activities include, without limitation,
specialist services and/or sercurities brokerage, sales, lending, custody,
clearance, settlement or trading.



    NONSOLICITATION.  During employment and until the later of 12 months
following termination of employment with us or the fifth anniversary of this
offering, a managing director or executive officer may not, directly or
indirectly:


    - solicit any of our listed companies;

    - interfere with or damage any relationship between us and any of our listed
      companies or prospective allocated companies; or

    - solicit any of our employees to apply for, or accept employment with, any
      competitive enterprise.

    TRANSITION ASSISTANCE. The noncompetition agreements also provide that each
managing director and each executive officer will take all actions and do all
things reasonably requested by us during a 90-day transition period following
termination of employment to maintain the business, goodwill and business
relationships in which or with which he or she was previously involved on our
behalf.


    LIQUIDATED DAMAGES.  If a managing director breaches the noncompetition or
nonsolicitation provisions of the noncompetition agreement before the later of
12 months following termination of employment with us or the fifth anniversary
of the date of the completion of this offering, then he or she will be liable
for liquidated damages in an amount equal to 75% of the aggregate value of the
common stock and cash received by that managing director from us in exchange for
his or her membership interest in LaB Investing Co. L.L.C. The noncompetition
agreement with our Executive Vice President, Finance does not provide for the
payment of liquidated damages.


THE PLEDGE AGREEMENTS


    Under each managing director's pledge agreement, the liquidated damages
obligations under each noncompetition agreement are secured by a pledge of
common stock with an initial value equal to 100% of the liquidated damages
amount. The pledge agreement will terminate with respect to a managing director
on the earliest to occur of:



    - the death of the managing director;



    - the fifth anniversary of the date of the completion of this offering; or



    - payment in cash or other satisfaction by the managing director of all
      liquidated damages incurred.


NONEXCLUSIVITY AND ARBITRATION

    The liquidated damages and pledge arrangements discussed above are not
exclusive of any injunctive relief to which we may be entitled for a breach of a
covenant against competition or solicitation. Prior to and after the expiration
of the pledge agreements, we will be entitled to all available remedies for a
breach of the noncompetition agreements. The employment and noncompetition
agreements generally provide that any disputes thereunder will be resolved by
binding arbitration.

                       INCENTIVE AWARDS TO OUR EMPLOYEES

THE EQUITY INCENTIVE PLAN

    The following is a description of the material terms of the LaBranche & Co
Inc. Equity Incentive Plan, which will become effective prior to the closing of
this offering. You should, however, refer to the exhibits that are a part of the
registration statement for a copy of the Equity Incentive Plan. See "Available
Information."


    Immediately prior to the closing of this offering, we will grant (1) options
to purchase an aggregate of 1,200,000 shares of our common stock at the initial
public offering price to our executive officers and (2) restricted stock units
for 1,059,000 shares of common stock to some of our employees who are not
managing directors. Subject to continuing service with us and other conditions,
the initial grant of options will generally become exercisable in three equal
annual installments commencing on the first anniversary of the date of grant and
restricted stock units will generally vest in three equal annual installments
commencing on the third anniversary of the grant date.



    TYPES OF AWARDS.  The Equity Incentive Plan provides for grants of options
to purchase shares of
our common stock, including options intended to qualify as incentive stock
options ("ISOs") (within the meaning of Section 422 of the Internal Revenue Code
of 1986, as amended) and options which do not qualify as ISOs ("NQSOs"),
restricted shares of our common stock, restricted stock units, the value of
which is tied to shares of our common stock and other equity-based awards
related to our common stock.



    AVAILABLE SHARES.  A maximum of 4,687,500 shares of our common stock has
been reserved for issuance under the Equity Incentive Plan. The number, class
and exercise price per share will be adjusted proportionately or as otherwise
appropriate to reflect any increase in, decrease in, or exchange of the
outstanding shares of our common stock through merger, consolidation,
recapitalization, reclassification, stock split, reverse stock split, stock
dividend or similar corporate transaction. These shares may be authorized but
unissued shares of our common stock or issued shares of our common stock held in
our treasury or otherwise acquired for the purposes of the Equity Incentive
Plan. New awards may be granted under the Equity Incentive Plan with respect to
shares of our common stock covered by any award that terminates or expires by
its terms (by cancellation or otherwise) or with respect to shares of our common
stock that are withheld or surrendered to satisfy a recipient's income tax or
other withholding obligations or tendered to pay the purchase price of any
award.


    The maximum number of shares of our common stock with respect to which
options, restricted stock, restricted stock units or other equity-based awards
may be granted under the Equity Incentive Plan during any calendar year to any
employee may not exceed 500,000 shares, subject to adjustment upon certain
corporate transactions (as described above).

    ELIGIBILITY.  Awards under the Equity Incentive Plan may be granted to any
of our directors, officers, managing directors or other employees, including any
prospective employee, and to any of our advisors or consultants selected by the
compensation committee of our board of directors.


    ADMINISTRATION.  The Equity Incentive Plan will be administered by the
compensation committee of our board of directors. The compensation committee
will have full discretion and authority to make awards under the Equity
Incentive Plan, to apply and interpret the provisions of the Equity Incentive
Plan and to take such other actions as may be necessary or desirable in order to
carry out the provisions of the Equity Incentive Plan. The determinations of the
compensation committee on all matters relating to the Equity Incentive Plan and
the options, restricted stock, restricted stock units and other equity-based
awards granted thereunder will be final, binding and conclusive.



    STOCK OPTIONS.  The compensation committee may grant ISOs and NQSOs in such
amounts and subject to such terms and conditions as it may determine. The
exercise price of an option granted


                                       54
<PAGE>

under the Equity Incentive Plan will not be less than the fair market value of
our common stock on the date of grant (as determined under the plan). Unless
sooner terminated or exercised, options will generally expire ten years from the
date of grant. Payment for shares acquired upon the exercise of an option may be
made (as determined by the compensation committee) in cash and/or such other
form of payment as may be permitted from time to time, which may include
previously-owned shares of our common stock or pursuant to a broker's cashless
exercise procedure. Except as otherwise permitted by the compensation committee,
no option may be exercised more than 30 days after termination of the optionee's
service (or, if the optionee's service is terminated by reason of disability or
death, one year thereafter). If an optionee's employment is terminated for
cause, options held by such optionee immediately terminate. An optionee will not
have any of the rights of a stockholder with respect to shares subject to an
option until the issuance of such shares.



    RESTRICTED STOCK.  The compensation committee may grant restricted shares of
our common stock in amounts, and subject to terms and conditions (such as time
vesting and/or performance-based vesting criteria) as it may determine.
Generally, prior to vesting, the recipient will have the rights of a stockholder
with respect to the restricted stock, subject to any restrictions and conditions
as the compensation committee may include in the award agreement.



    RESTRICTED STOCK UNITS.  The compensation committee may grant restricted
stock units, the value of which is tied to shares of our common stock, in
amounts, and subject to terms and conditions, as the compensation committee may
determine. Recipients of restricted stock units have only the rights of our
general unsecured creditors and no rights as a stockholder until the common
stock referenced by the restricted stock units, is delivered to the recipient.



    OTHER EQUITY-BASED AWARDS.  The compensation committee may grant other types
of equity-based awards related to our common stock under the Equity Incentive
Plan, including the grant of unrestricted shares of our common stock and stock
appreciation rights, in amounts and subject to terms and conditions as the
compensation committee may determine. These awards may involve the transfer of
actual shares of common stock or the payment in cash or otherwise of amounts
based on the value of shares of our common stock.



    CHANGE IN CONTROL.  The compensation committee may provide, in any award
agreement, for provisions relating to a "change in control" of us or any of our
subsidiaries or affiliates, including, without limitation, the acceleration of
the exercisability of, or the lapse of restrictions with respect to, the award.



    NONASSIGNABILITY.  Except to the extent otherwise provided in an award
agreement or approved by the compensation committee with respect to NQSOs, no
award granted under the Equity Incentive Plan will be assignable or transferable
other than by will or by the laws of descent and distribution and all awards
will be exercisable during the life of a recipient only by the recipient or his
or her legal representative.


    AMENDMENT AND TERMINATION.  The Equity Incentive Plan may be amended or
terminated at any time by our board of directors, subject, however, to
stockholder approval in the case of certain material amendments, such as an
increase in the number of shares available under the Equity Incentive Plan or a
change in the class of individuals eligible to participate in the Equity
Incentive Plan.

    U.S. FEDERAL INCOME TAX CONSEQUENCES.  The following is a brief description
of the material U.S. federal income tax consequences generally arising with
respect to awards granted under the Equity Incentive Plan.

    The grant of an option will have no income tax consequences to the recipient
or to us. Upon the exercise of an option, other than an ISO, the recipient
generally will recognize ordinary income equal to the excess of the fair market
value of the shares of common stock subject to the option on the date

                                       55
<PAGE>
of exercise over the exercise price for such shares (i.e., the option spread),
and we generally will be entitled to a corresponding tax deduction in the same
amount. Upon the sale of the shares of our common stock acquired pursuant to the
exercise of an option, the recipient will recognize capital gain or loss equal
to the difference between the selling price and the sum of the exercise price
plus the amount of ordinary income recognized on the exercise.

    A recipient generally will not recognize ordinary income upon the exercise
of an ISO (although, on exercise, the option spread is an item of tax preference
income potentially subject to the alternative minimum tax) and we will not
receive any deduction. If the stock acquired upon exercise of an ISO is sold or
otherwise disposed of within two years from the grant date or within one year
from the exercise date, then gain realized on the sale generally is treated as
ordinary income to the extent of the ordinary income that would have been
realized upon exercise if the option had not been an ISO, and we generally will
be entitled to a corresponding deduction in the same amount. Any remaining gain
is treated as capital gain.

    If the shares acquired upon the exercise of an ISO are held for at least two
years from the grant date and one year from the exercise date and the recipient
is employed by us at all times beginning on the grant date and ending on the
date three months prior to the exercise date, then all gain or loss realized
upon the sale will be capital gain or loss and we will not receive any
deduction.

    In general, an individual who receives an award of restricted stock will
recognize ordinary income at the time such award vests in an amount equal to the
difference between the value of the vested shares and the purchase price for
such shares, if any, and we generally will be entitled to a deduction in an
amount equal to the ordinary income recognized by the recipient at such time.

    The recipient of an award of restricted stock units generally will recognize
ordinary income upon the issuance of the shares of common stock underlying such
restricted stock units in an amount equal to the difference between the value of
such shares and the purchase price for such units and/or shares, if any, and we
generally will be entitled to a deduction in an amount equal to the ordinary
income recognized by the recipient a such time.


    With respect to other equity-based awards, upon the payment of cash or the
issuance of shares or other property that is either not restricted as to
transferability or not subject to a substantial risk of forfeiture, the
participant will generally recognize ordinary income equal to the cash or the
fair market value of shares or other property delivered, less any amount paid by
the participant for such award. Generally, we will be entitled to a deduction in
an amount equal to the ordinary income recognized by the participant.


THE ANNUAL INCENTIVE PLAN


    The board of directors will adopt, effective upon the closing of this
offering, the LaBranche & Co Inc. Annual Incentive Plan. Our managing directors
and other employees selected by the compensation committee of our board of
directors will be eligible to participate in the Annual Incentive Plan. Under
this plan, a compensation pool of up to 30% of our pre-tax income, or such
lesser percentage determined by the compensation committee, will be set aside
for our managing directors and other employees selected by the compensation
committee to participate in this plan. In determining the 30% compensation pool,
the compensation expenses relating to the grant of restricted stock units at the
time of this offering will be deducted. Under the plan, no individual
participant may receive more than 25% of the compensation pool for any fiscal
year. The amounts payable under the Annual Incentive Plan to our plan
participants will be reviewed on an annual basis and will be based on such
factors and considerations as the compensation committee deems appropriate in
individual cases and on our operating results and the overall performance of
these participants. An award made by the compensation committee to our managing
directors and other employees is completely discretionary. The Annual Incentive
Plan may be amended or terminated at any time by our board of directors.

percentage of the person holding such securities but are not treated as
outstanding for computing the percentage of any other person.

      aggregate of $10.0 million in cash as part of their exchange. All the
      members of LaB Investing Co. L.L.C. are managing directors, and all
      members who will remain employed by us following this offering are only
      receiving shares of our common stock, and no cash, in the reorganization.
      We thus will become the sole member of LaB Investing Co. L.L.C., and LaB
      Investing Co. L.L.C. will continue to be the general partner of LaBranche
      & Co. Our common stock to be received by the members of LaB Investing Co.
      L.L.C. will be subject to certain restrictions, as described below under
      "--Stockholders' Agreement." Set forth below is the percentage interest in
      the profits of LaBranche & Co. owned by each of our Named Executive
      Officers, as members of LaB Investing Co. L.L.C., before giving effect to
      the reorganization and the number of shares of our common stock that each
      of our Named Executive Officers will receive upon the closing of this
      offering:

    - The 19 limited partners of LaBranche & Co., other than Mill Bridge, Inc.,
      have agreed, subject to the completion of this offering and our note
      offering, to exchange their limited partnership interests in LaBranche &
      Co. which represented a 16.4% interest in the profits of LaBranche & Co.
      to us in exchange for an aggregate of $68.1 million in cash, 625,000
      shares of our common stock and subordinated indebtedness of $350,000
      issued to a family member of Mr. Gallagher. The shares of our common stock
      received by limited partners will be subject to lock-up restrictions which
      will prohibit the transfer of 50% of those shares for a period of one year
      and the remaining 50% for a period of two years following this offering.


    - Mill Bridge, Inc., a subsidiary of Van der Moolen Holding NV, will receive
      $90.0 million from us, including $74.0 million in cash upon the closing of
      this offering and our note offering and a subordinated note for $16.0
      million, in exchange for its limited partnership interest in LaBranche &
      Co., which represented a 14.2% interest in the profit of LaBranche & Co.

    - As a result of the above transactions, we will become the sole limited
      partner of LaBranche & Co., which will continue to be a broker-dealer and
      a NYSE specialist firm.


    - Immediately prior to the closing of this offering, we will grant options
      under the Equity Incentive Plan to purchase an aggregate of 1,200,000
      shares of our common stock to our executive officers. These options have
      an exercise price equal to the initial offering price and are not
      currently exercisable.



    - Immediately prior to the closing of this offering, we will grant
      restricted stock units under the Equity Incentive Plan for 1,059,000
      shares of our common stock to employees who are not managing directors.
      These restricted stock units are not vested.

    - Prior to the closing of this offering, we will completely discharge our
      remaining obligations under all outstanding loans received from the
      LaBranche & Co. Retirement Plan by making a single lump sum payment in the
      amount of $1.1 million to the plan. Since certain of our executive
      officers directed the plan to lend to us a portion of the amounts credited
      to their individual accounts under the plan, part of the proceeds of our
      payment will be allocated to those individual accounts in accordance with
      the terms of the plan.



    The consideration paid to the members and limited partners in connection
with the reorganization was arrived at through negotiation.


STOCKHOLDERS' AGREEMENT

    We intend to enter into a stockholders' agreement with all 36 members of LaB
Investing Co. L.L.C. who will be receiving our common stock in the
reorganization, 33 of whom will remain managing directors following this
offering, and with the employees who will receive options and restricted stock
or restricted stock unit awards in connection with the reorganization. This
stockholders' agreement will contain various restrictions on the transfer of our
stock by the parties to such agreement and a voting agreement.

    TRANSFER RESTRICTIONS.  The stockholders' agreement will prohibit the
transfer of our shares by the former members of LaB Investing Co. L.L.C. and our
employees who receive our common stock in the reorganization for a period of
three years following this offering. Beginning on the third anniversary of this
offering, up to one-third of these shares may be transferred. Beginning on the
fourth anniversary, up to an additional one-third of these shares may be
transferred, and beginning on the fifth anniversary, all of these shares may be
transferred. Notwithstanding this,

    - if the stockholder is employed by us, at all times during the course of
      his or her employment, he or she must retain at least 25% of the aggregate
      of the shares of our common stock received in the reorganization and other
      shares received under the Equity Incentive Plan or similar plans; and

    - an employee may not sell shares of our common stock which are subject to a
      pledge agreement, unless the requirements of the pledge agreement are
      waived by us.

    VOTING AGREEMENT.  The shares owned by each party to the stockholders'
agreement will be voted at the general stockholder vote as directed by Messrs.
LaBranche, Gallagher and Hayward, as determined by a majority of those
individuals. These individuals will name alternates to replace them in the event
of their death or disability.

INTEREST ON INDEBTEDNESS


    A family member of Mr. Flaherty holds $600,000 of subordinated indebtedness
due August 31, 1999, and Mr. LaBranche's spouse holds $1.3 million of
subordinated indebtedness due March 2, 2000. This debt bears interest at an
annual rate of 10.0% payable on a quarterly basis. The agreements relating to
this debt have automatic rollover provisions which extend the maturities for an
additional year, unless the lender provides notice at least seven months prior
to maturity. The interest income in 1998 for Mr. Flaherty's family member was
$60,000 and the interest income in 1998 for Mr. LaBranche's spouse was $71,250.


                          DESCRIPTION OF CAPITAL STOCK

    Upon the closing of this offering and the filing of the amendment to our
certificate of incorporation referred to below, our authorized capital stock
will consist of 200,000,000 shares of common stock, $.01 par value, and
10,000,000 shares of preferred stock, $.01 par value. Upon the closing of this
offering, and after giving effect to the issuance of 11,500,000 shares of common
stock offered by us hereby, there will be 46,875,000 shares of common stock and
no shares of preferred stock issued and outstanding. See "--Preferred Stock."

COMMON STOCK

    Subject to preferences that may be applicable to any preferred stock
outstanding at the time, the holders of outstanding shares of common stock are
entitled to receive dividends out of assets legally available therefor at such
times and in such amounts as the board of directors from time to time may
determine. Holders of common stock are entitled to one vote for each share held
on all matters submitted to a vote of stockholders. Cumulative voting for the
election of directors is not authorized by our certificate of incorporation,
which means that the holders of a majority of the shares voted can elect all of
the directors then standing for election. The common stock is not entitled to
preemptive rights and is not subject to conversion or redemption. Upon our
liquidation, dissolution or winding-up, the assets legally available for
distribution to stockholders shall be distributed ratably among the holders of
our common stock after payment of liquidation preferences, if any, on any
outstanding shares of preferred stock and payment of other claims of creditors.
Each outstanding share of common stock is, to be outstanding upon completion of
this offering will be upon payment therefor, duly and validly issued, fully paid
and nonassessable.

    There is currently no active trading market for our common stock.
Application will be made to have our common stock approved for listing on the
NYSE under the symbol "LAB."

PREFERRED STOCK

    The 10,000,000 authorized shares of preferred stock may by issued in one or
more series without further stockholder authorization, and the board of
directors is authorized to fix and determine the terms, limitations and relative
rights and preferences of the preferred stock, to establish series of preferred
stock and to fix and determine the variations as among series. If we issue
preferred stock, it would have priority over our common stock with respect to
dividends and to other distributions, including the distribution of assets upon
liquidation, and we may be obligated to repurchase or redeem it. The board of
directors can issue preferred stock without the approval of our common
stockholders. Preferred stock may have voting and conversion rights (including
multiple voting rights) which could adversely affect the rights of holders of
common stock. In addition to having a preference with respect

                                       60
<PAGE>
to dividends or liquidation proceeds, if preferred stock is issued, it may be
entitled to the allocation of capital gains from the sale of our assets. We do
not have any present plans to issue any shares of preferred stock.

DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER PROVISIONS

    Under Section 203 of the Delaware General Corporation Law (the "Delaware
anti-takeover law"), certain "business combinations" between a Delaware
corporation, whose stock generally is publicly traded or held of record by more
than 2,000 stockholders, and an "interested stockholder" are prohibited for a
three-year period following the date that such stockholder became an interested
stockholder, unless


    - the corporation has elected in its certificate of incorporation or bylaws
      not to be governed by the Delaware anti-takeover law (we have not made
      such an election);


    - the business combination was approved by the board of directors of the
      corporation before the other party to the business combination became an
      interested stockholder;

    - upon consummation of the transaction that made it an interested
      stockholder, the interested stockholder owned at least 85% of the voting
      stock of the corporation outstanding at the commencement of the
      transaction (excluding voting stock owned by directors who are also
      officers or held in employee stock plans in which the employees do not
      have a right to determine confidentially whether to tender or vote stock
      held by the plan); or

    - the business combination was approved by the board of directors of the
      corporation and ratified by two-thirds of the voting stock which the
      interested stockholder did not own. The three-year prohibition does not
      apply to certain business combinations proposed by an interested
      stockholder following the announcement or notification of certain
      extraordinary transactions involving the corporation and a person who had
      not been an interested stockholder during the previous three years or who
      became an interested stockholder with the approval of a majority of the
      corporation's directors. The term "business combination" is defined
      generally to include mergers or consolidations between a Delaware
      corporation and an interested stockholder, transactions with an interested
      stockholder involving the assets or stock of the corporation or its
      majority-owned subsidiaries and transactions which increase an interested
      stockholder's percentage ownership of stock. The term "interested
      stockholder" is defined generally as a stockholder who becomes beneficial
      owner of 15% or more of a Delaware corporation's voting stock. Section 203
      could have the effect of delaying, deferring or preventing a change in
      control of LaBranche & Co Inc.


    In addition, provisions of our certificate of incorporation and bylaws which
will take effect upon the closing of the offering and which are summarized in
the following paragraphs, may have an anti-takeover effect and may delay, defer
or prevent a tender offer or takeover attempt that a stockholder might consider
in its best interest, including those attempts that might result in a premium
over the market price for the shares held by our stockholders.


    CLASSIFIED BOARD OF DIRECTORS


    Following this offering, our board of directors will be divided into three
classes of directors serving staggered three-year terms. As a result,
approximately one-third of the board of directors will be elected each year.
These provisions, when coupled with the provision of our certificate of
incorporation authorizing the board of directors to fill vacant directorships or
increase the size of the board of directors, may deter a stockholder from
removing incumbent directors and simultaneously gaining control of the board of
directors by filling the vacancies created by such removal with its own
nominees.


                                       61
<PAGE>
    STOCKHOLDER ACTION; SPECIAL MEETINGS OF STOCKHOLDERS


    Our bylaws provide that our stockholders may not take action by written
consent, but only at an annual or special meeting of stockholders. Our by-laws
further provide that special meetings of our stockholders may be called only by
the chairman of the board of directors or a majority of the board of directors.


    SUPERMAJORITY VOTING PROVISIONS

    Our certificate of incorporation provides that the affirmative vote of at
least two-thirds of our stockholders is required to amend the provisions of our
certificate and by-laws relating to the classification of the board of
directors, stockholder action by written consent and the calling of special
meetings.

    AUTHORIZED BUT UNISSUED SHARES

    The authorized but unissued shares of common stock and preferred stock are
available for future issuance without stockholder approval. These additional
shares may be utilized for a variety of corporate purposes, including future
public offerings to raise additional capital, corporate acquisitions and
employee benefit plans. The existence of authorized by unissued common stock and
preferred stock could render more difficult or discourage an attempt to obtain
control of LaBranche & Co Inc. by means of a proxy contest, tender offer, merger
or otherwise.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS

    We will enter into indemnification agreements with our current directors and
executive officers. These provisions and agreements may have the practical
effect in some cases of eliminating our stockholders' ability to collect
monetary damages from our directors. We believe that these contractual
agreements and the provisions in our certificate of incorporation and by-laws
are necessary to attract and retain qualified persons as directors and officers.

TRANSFER AGENT AND REGISTRAR


    The Transfer Agent and Registrar for the common stock is Firstar Bank, N.A.


                        SHARES ELIGIBLE FOR FUTURE SALE

    Prior to this offering, there has been no public market for our common
stock, and we cannot predict the effect, if any, that market sales of shares or
the availability of any shares for sale will have on the market price of the
common stock prevailing from time to time. Sales of substantial amounts of
common stock, or the perception that such sales could occur, could adversely
affect the market price of our common stock and our ability to raise capital
through a sale of our securities.

    Upon completion of this offering, we will have 46,875,000 shares of common
stock outstanding (or 48,600,000 shares if the underwriters over-allotment
option is exercised in full).

    In connection with the reorganization of our firm from partnership to
corporate form, our managing directors and limited partners who are exchanging
their interests for 35,375,000 restricted shares of our common stock have
contractually agreed that they will not sell their common stock for various time
periods after this offering. Under these contractual restrictions, these
restricted shares are eligible for sale in the public market as follows:

    In addition:


    - each of our managing directors must retain 25% of his or her common stock,
      currently totaling 8,501,318 shares in the aggregate, for the duration of
      his or her employment; and


    - an employee may not sell shares of our common stock that are subject to a
      pledge agreement, unless the requirements of the pledge agreement are
      waived by us.

    The 11,500,000 shares (or up to 13,225,000 shares if the underwriters'
over-allotment option is exercised in full) of common stock sold in this
offering will be freely tradable without further restriction or further
registration under the Securities Act, except for shares purchased by any of our
affiliates (as this term is defined in the Securities Act), which will be
subject to the limitations of Rule 144 under the Securities Act. Subject to
certain contractual limitations, holders of restricted shares generally will be
entitled to sell these shares in the public securities market without
registration either pursuant to Rule 144 or any other applicable exemption under
the Securities Act.


    In general, under Rule 144 under the Securities Act, a person (or persons
whose shares are aggregated) who has beneficially owned restricted securities
within the meaning of Rule 144 for at least one year, and including the holding
period of any prior owner except an affiliate, would be entitled to sell within
any three-month period a number of shares that does not exceed the greater of
one percent of the then outstanding shares of common stock or the average weekly
trading volume of the common stock on the NYSE during the four calendar weeks
preceding such sale. Sales under Rule 144 are also subject to certain manner of
sale provisions, notice requirements and the availability of current public
information about LaBranche & Co Inc. Any person (or persons whose shares are
aggregated) who is not deemed to have been our affiliate at any time during the
three months preceding a sale, and who has beneficially owned shares for at
least two years (including any period of ownership of preceding non-affiliated
holders), would be entitled to sell such shares under Rule 144(k) without regard
to the volume limitations, manner of sale provisions, public information
requirements or notice requirements. An "affiliate" is a person that directly,
or indirectly through one or more intermediaries, controls, or is controlled by,
or under common control with, such issuer.


    We intend to file one or more registration statements under the Securities
Act to register 4,687,500 shares of common stock subject to outstanding stock
options or reserved for issuance under our equity compensation plans. Upon
completion of this offering, options to purchase approximately 1,200,000 shares
and 1,059,000 restricted stock units will be outstanding under our equity
compensation plans.

    Our directors and officers and our stockholders who hold 35,375,000 shares
in the aggregate have entered into lock-up agreements. Pursuant to these
agreements, they have agreed not to sell, directly or indirectly, any shares of
common stock without the prior written consent of Salomon Smith Barney Inc. for
a period of 180 days from the date of this prospectus. However, they may gift or
transfer shares so long as the donee or transferee agrees to be bound by the
terms of the lock-up agreement.

    The underwriters are obligated to purchase all the shares (other than those
covered by the over-allotment option described below) if they purchase any of
the shares.



    The underwriters, for whom Salomon Smith Barney Inc., Donaldson, Lufkin &
Jenrette Securities Corporation and ABN AMRO Incorporated are acting as
representatives, propose to offer some of the shares directly to the public at
the public offering price set forth on the cover page of this prospectus and
some of the shares to certain dealers at the public offering price less a
concession not in excess of $         per share. The underwriters may allow, and
such dealers may reallow, a concession not in excess of $         per share on
sales to certain other dealers. If all of the shares are not sold at the initial
offering price, the representatives may change the public offering price and the
other selling terms. The representatives have advised us that the underwriters
do not intend to confirm any sales to any accounts over which they exercise
discretionary authority.


    We have granted to the underwriters an option, exercisable for 30 days from
the date of this prospectus, to purchase up to 1,725,000 additional shares of
common stock at the public offering price less the underwriting discount. The
underwriters may exercise such option solely for the purpose of covering
over-allotments, if any, in connection with this offering. To the extent such
option is exercised, each underwriter will be obligated, subject to certain
conditions, to purchase a number of additional shares approximately
proportionate to such underwriter's initial purchase commitment.

    We and our officers, directors and stockholders have agreed that, for a
period of 180 days from the date of this prospectus, they will not, without the
prior written consent of Salomon Smith Barney Inc., dispose of or hedge any
shares of our common stock or any securities convertible into or exchangeable
for our common stock. Salomon Smith Barney Inc. in its sole discretion may
release any of the securities subject to these lock-up agreements at any time
without notice.

    Prior to this offering, there has been no public market for the common
stock. Consequently, the initial public offering price for the shares was
determined by negotiations between us and the representatives for the
underwriters. Among the factors considered in determining the initial public
offering price were our record of operations, our current financial condition,
our future prospects, our markets, the economic conditions in and future
prospects for the industry in which we compete, our management, and currently
prevailing general conditions in the equity securities markets, including
current market valuations of publicly traded companies considered comparable to
us. There can be no assurance, however, that the prices at which the shares will
sell in the public market after this offering will not be lower than the price
at which they are sold by the underwriters or that an active trading market in
the common stock will develop and continue after this offering.


    The common stock has been approved for listing on the NYSE under the symbol
"LAB."


    The following table shows the underwriting fees to be paid to the
underwriters by us, in connection with this offering. The underwriting fee is
equal to the public offering price per share of common stock

                                       64
<PAGE>
less the amount paid by the underwriters to us per share of common stock. The
underwriting fees are shown assuming both no exercise and full exercise of the
underwriters' option to purchase additional shares of our common stock. The
underwriters will not receive any additional compensation in connection with
this offering.

    In connection with the offering, Salomon Smith Barney Inc., on behalf of the
underwriters, may purchase and sell shares of common stock in the open market.
These transactions may include over-allotment, syndicate covering transactions
and stabilizing transactions. Over-allotment involves syndicate sales of common
stock in excess of the number of shares to be purchased by the underwriters in
the offering, which creates a syndicate short position. Syndicate covering
transactions involve purchases of the common stock in the open market after the
distribution has been completed in order to cover syndicate short positions.
Stabilizing transactions consist of certain bids or purchases of common stock
made for the purpose of preventing or retarding a decline in the market price of
the common stock while the offering is in progress.


    The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when
Salomon Smith Barney Inc., in covering syndicate short positions or making
stabilizing purchases, repurchases shares originally sold by that syndicate
member.

    Any of these activities may cause the price of the common stock to be higher
than the price that otherwise would exist in the open market in the absence of
such transactions. These transactions may be effected on the NYSE or in the
over-the-counter market, or otherwise and, if commenced, may be discontinued at
any time.

    We estimate that our total offering expenses will be approximately $1.6
million. Offering expenses are expenses incurred by us in connection with this
offering and include filing fees, NYSE listing fees, printing expenses and legal
and accounting expenses. We will pay all these offering expenses.


    The representatives may, from time to time, engage in transactions with and
perform services for us in the ordinary course of their business. Certain of the
underwriters are acting as the initial purchasers in our note offering. In
addition, we act as specialist for ABN AMRO Holding N.V. ADRs listed on the
NYSE. Therefore, we may be obligated at times to buy or sell these ADRs to
counter short-term imbalances in the prevailing market. At other times we may
trade these ADRs at our own election.


    We have agreed to indemnify the underwriters against civil liabilities,
including liabilities under the Securities Act of 1933 for any losses arising
out of any material misstatements or omissions by us in this prospectus or any
misrepresentation by us in the underwriting ageement. In addition, we have
agreed to contribute to payments the underwriters may be required to make in
respect of any of those liabilities.

                                 LEGAL MATTERS

    The validity of the shares of common stock offered hereby will be passed
upon for LaBranche & Co Inc. by Fulbright & Jaworski L.L.P., New York, New York,
and for the underwriters by Cleary, Gottlieb, Steen & Hamilton, New York, New
York.

                  PRO FORMA CONSOLIDATED FINANCIAL INFORMATION
                                  (UNAUDITED)

                                    OVERVIEW


    The following pro forma consolidated financial information is based on the
historical consolidated financial statements of LaBranche & Co. and LaB
Investing Co. L.L.C., its sole general partner (together, the "Partnership"),
after giving effect to the acquisition of Fowler, Rosenau & Geary, LLC ("Fowler,
Rosenau") and the reorganization and related transactions (the "Reorganization
Transactions") to convert the Partnership to corporate form. The Reorganization
Transactions are described in greater detail below. The pro forma as adjusted
consolidated statement of financial condition presents the Reorganization
Transactions as if they occurred on June 30, 1999 and gives effect to the
completion of the initial public offering. The pro forma consolidated statement
of operations for the six months ended June 30, 1999 and for the year ended
December 31, 1998 present the results of the Partnership as if the
Reorganization Transactions had occurred on January 1, 1998. Additionally, the
pro forma consolidated statement of operations for the year ended December 31,
1998 present the results of the Partnership as if the acquisition of Fowler,
Rosenau had occurred on January 1, 1998.


    Effective July 1, 1998, the Partnership acquired the specialist operations
of Fowler, Rosenau for an aggregate purchase price of approximately $45.0
million, representing a 22.4% total general and limited partners' interest in
the Partnership. The acquisition of Fowler, Rosenau was accounted for under the
purchase method of accounting. The purchase price consisted of general and
limited partnership interests issued to new partners admitted into the
Partnership. The limited partners' interests were issued by LaBranche & Co. The
excess purchase price over fair value of net assets acquired of approximately
$25.8 million has been allocated to goodwill, which is being amortized over a
15-year period. The following unaudited pro forma consolidated financial
statement of operations for the year ended December 31, 1998 gives effect to
this acquisition as if it had occurred on January 1, 1998, by consolidating the
results of operations of Fowler, Rosenau for the six months ended June 30, 1998
with the results of operations of the Partnership, which include the results of
Fowler, Rosenau after June 30, 1998, for the year ended December 31, 1998.

    The Partnership is not currently subject to federal or state income taxes,
but is currently subject to New York City unincorporated business tax. Following
the Reorganization Transactions, LaBranche & Co Inc., on a consolidated basis,
will be subject to federal, state and local income taxes. Concurrently with the
closing of the offering, the Partnership will complete the following
Reorganization Transactions:


    - The limited partners of LaBranche & Co. will redeem their interests for
      $142.1 million in cash, a $16.0 million subordinated note, $350,000 of
      subordinated indebtedness and 625,000 shares of our common stock assumed
      to have a value of $10.0 million, for a total purchase price of $168.4
      million.


    - The members of LaB Investing Co. L.L.C. will exchange their membership
      interests in LaB Investing Co. L.L.C. for $10.0 million in cash and
      34,750,000 shares of common stock of LaBranche & Co Inc.

    - $5.0 million of subordinated debt at an interest rate of 10.0% is assumed
      to be repaid.

    In addition, simultaneously with the initial public offering, LaBranche & Co
Inc. will incur indebtedness of approximately $100.0 million. The proceeds of
the indebtedness, net of estimated issuance costs of approximately $3.0 million,
are assumed to be used to redeem a portion of the limited partners' interests in
LaBranche & Co. and withdrawing members' interests.

                                      F-3

    The redemption of the limited partners' interest is accounted for as a step
acquisition under the purchase method of accounting. The excess of purchase
price over the limited partners' capital accounts is allocated to intangible
assets with corresponding respective lives as follows:

</TABLE>


    The allocation of purchase price and determination of useful lives was based
upon an independent appraisal. The useful life of the specialist stock list was
determined based upon analysis of historical turnover characteristics of the
specialist stocks.



    Historically, the Partnership paid substantially all its earnings to its
members as managing directors' compensation. Upon reorganization to corporate
form, managing directors will become employees of the corporation. The Board of
Directors of LaBranche & Co Inc. will approve the LaBranche & Co Inc. Annual
Incentive Plan (the "Plan") upon completion of the offering. Under the Plan, a
compensation pool of up to 30% of pre-tax income, which is assumed to include
related employee benefits, will be set aside for managing directors and other
employees. In determining the 30% compensation pool, compensation expenses
relating to the grant of restricted stock units at the time of this offering
will be deducted. Managing directors will also be paid base annual compensation
of amounts ranging between $150,000 to $250,000. Such base amounts are
considered to be drawn against the 30% compensation pool.


    The pro forma consolidated financial information has been prepared by the
Partnership's management and is not necessarily indicative of the results that
would have been achieved had the acquisition of Fowler, Rosenau and the
Reorganization Transactions occurred on the dates indicated or that may be
achieved in the future. The pro forma consolidated financial information should
be read in conjunction with the audited consolidated financial statements of the
Partnership as of December 31, 1998 and 1997 and the three years in the period
ended December 31, 1998, the notes thereto, and the unaudited consolidated
financial statements as of June 30, 1999 and the six months in the periods ended
June 30, 1999 and 1998, and the notes thereto.

             NOTES TO PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

                                  (UNAUDITED)

(A) Reflects net proceeds received for issuance of long-term indebtedness. Debt
    issuance costs are estimated to approximate $3.0 million.


(B) Reflects the redemption of limited partnership interests in exchange for
    $168.4 million, comprised of $142.1 million in cash, a $16.0 million
    subordinated note and $350,000 of subordinated indebtedness (see note (G))
    and $10.0 million in common stock.


(C) Reflects redemption of members' interest for $10.0 million.

(D) Reflects pro forma repayment of $5.0 million of subordinated liabilities
    owed to a limited partner and reverses the related interest expense.

(E) Reflects $131.3 million of purchase price allocated to intangibles for the
    redemption of limited partnership interests.

    be used for redemption of limited partners' and members' interest and the
    related interest expense.

    assumed to include related employee benefits, will be set aside for managing
    directors and other employees. The pro forma compensation adjustment
    reflects managing directors' compensation, which is comprised of an annual
    base salary of approximately $6.3 million (36 managing directors at

    (2.5% of total managing directors' compensation) and the remaining balance
    as bonus, as well as compensation expenses related to employee restricted
    stock awards of $17.0 million which vest over 5 years and result in an
    annual expense of $3.4 million. The pro forma adjustment does not include
    any other compensation expenses related to employees who are not managing
    directors.



(J) Reflects pro forma amortization of intangibles related to redemption of
    limited partners' interests.



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



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



(M) Reflects federal, state and local income taxes at an estimated effective tax
    rate of approximately 44%.

    units for 1,059,000 shares of common stock, in each case granted under the
    Equity Incentive Plan.



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



(P) Reflects the pro forma amortization of intangibles for the six months ended
    June 30, 1998 related to the Fowler, Rosenau acquisition.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Members of
LaB Investing Co. L.L.C. and Subsidiary:

    We have audited the accompanying consolidated statements of financial
condition of LaB Investing Co. L.L.C. and Subsidiary as of December 31, 1998 and
1997, and the related consolidated statements of operations, changes in members'
capital and cash flows for the three years in the period ended December 31,
1998. These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of LaB Investing Co. L.L.C. and
Subsidiary as of December 31, 1998 and 1997, and the results of their operations
and their cash flows for the three years in the period ended December 31, 1998
in conformity with generally accepted accounting principles.

    Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The parent company only condensed
financial statements appearing on pages F-19 through F-23 are presented for the
purpose of complying with the Securities and Exchange Commission's rules and are
not part of the basic financial statements. Such statements have been subjected
to the auditing procedures applied in the audit of the basic financial
statements and, in our opinion, are fairly stated in all material respects in
relation to the basic financial statements taken as a whole.

2. INTERIM CONSOLIDATED FINANCIAL STATEMENTS AND FINANCIAL INFORMATION

    The unaudited interim consolidated financial information as of June 30, 1999
and for the six months ended June 30, 1999 and 1998, are presented in the
accompanying consolidated financial statements. The unaudited interim
consolidated financial information reflects all adjustments, which are, in the
opinion of management, necessary for a fair presentation of the results for such
periods. Results of the interim periods are not necessarily indicative of
results to be obtained for a full fiscal year.

3. SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

    The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities at

revenues and expenses during the reporting period. Management does not believe
that actual results will differ materially from these estimates.


INTANGIBLE ASSETS


    Intangible assets are soley comprised of goodwill. Goodwill is being
amortized on a straight-line basis over 15 years. Subsequent to its acquisition,
the Partnership continually evaluates whether later events and circumstances
have occurred that indicate the remaining estimated useful life may warrant
revision or that the remaining balance may not be recoverable. When factors
indicate that intangible assets should be evaluated for possible impairment, the
Partnership uses an estimate of the undiscounted net income over the remaining
life in measuring whether the assets are recoverable.

EXCHANGE MEMBERSHIPS

    Exchange memberships owned by the Partnership are carried at cost.

    Certain members of the Partnership have contributed the use of 10
memberships on the NYSE to the Partnership. These memberships are subordinated
to claims of general creditors and are carried at market value with a
corresponding amount recorded in subordinated liabilities. Lease payments are
paid by the Partnership to the members and limited partners for the use of the
exchange memberships at a rate management believes is commensurate with the rent
paid to nonaffiliated parties for the use of their exchange memberships.

3. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
CASH AND CASH EQUIVALENTS

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

SECURITIES TRANSACTIONS

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

DEPRECIATION AND AMORTIZATION

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

COLLATERALIZED FINANCING TRANSACTIONS

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

COLLATERAL

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

REPORTABLE OPERATING SEGMENT

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

MANAGING DIRECTORS' COMPENSATION

    The managing directors of LaBranche & Co. are the members of LaB Investing.
The Partnership pays out substantially all of its earnings as compensation
expense to its managing directors.

</TABLE>

5. TAXES

    The Partnership is not subject to federal or state income taxes. Such taxes,
if any, are the responsibility of the individual members. The Partnership is
subject to the New York City Unincorporated Business Tax.

6. CAPITAL AND NET LIQUID ASSET REQUIREMENTS

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


    As of June 30, 1999 (unaudited) and as of December 31, 1998, LaBranche &
Co.'s net capital, as defined under SEC Rule 15c3-1, was $99,993,833 and
$86,545,533, respectively, and exceeded minimum requirements by $96,820,130 and
$85,169,019, respectively. LaBranche & Co.'s aggregate indebtedness to net
capital ratio was .48 to 1 and .42 to 1, respectively.



    The NYSE also requires members registered as regular specialists to
establish that they can meet, with their own net liquid assets, a minimum dollar
amount which shall be the greater of $1,000,000 or 25% of their position
requirement ("Rule 104.2"). In 1998, due to the market share represented by the
Partnership's specialist book, the NYSE mandated the firm to maintain minimum
net liquid assets of the greater of 120% of LaBranche & Co.'s Rule 104.2
position requirement, or $90.0 million, adjusted by the amount of the position
requirement for any new stock allocations. The position requirement is the
ability to assume positions in stocks in which they are registered, of 30,000
shares of each S&P 500 common stock, 22,500 shares in all other common stocks,
4,500 shares in each convertible preferred stock and 1,800 shares in each
nonconvertible preferred stock. The term "net liquid assets" for a specialist
which also engages in transactions other than specialist activities is based
upon its excess net capital determined in accordance with SEC Rule 15c3-1.


    As of June 30, 1999 (unaudited) and as of December 31, 1998, the
Partnership's NYSE minimum required dollar amount of net liquid assets, as
defined, was $91.5 million and $90.6 million, respectively, compared to actual
net liquid assets, as defined, of $116,251,755 and $103,134,594, respectively.

7. ACQUISITIONS

    The acquisitions of the specialist operations described below were accounted
for under the purchase method of accounting. The purchase price associated with
each acquisition consisted of general partnership and limited partnership
interests issued to new partners admitted into the Partnership. Such partnership
interests were valued based upon an independent appraisal. Excess purchase price
over fair value of net assets acquired has been allocated to goodwill.

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

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


    Effective July 1, 1998, the Partnership acquired the specialist operations
of Fowler, Rosenau & Geary, LLC ("Fowler, Rosenau") for an aggregate purchase
price of approximately $45.0 million representing a 22.4% total general and
limited partners' interest in the Partnership. The excess purchase price over
fair value of net assets acquired was approximately $25.8 million (The audited
financial statements of Fowler, Rosenau have been included elsewhere in this
prospectus).


8. COMMITMENTS

    During 1998, the Partnership secured a $75.0 million committed line of
credit with The Bank of New York. The agreement matured on June 25, 1999. In
June 1999, the Partnership amended and extended the committed line of credit to
$100.0 million through June 23, 2000 (unaudited). In addition, the Partnership
has outstanding letter of credit agreements with U.S. Trust aggregating
approximately $1,581,000. Such letter of credit agreements are collateralized
with U.S. Trust by a Treasury bill with a face value of $1.5 million and a cash
balance of approximately $179,000.

    Minimum rental commitments under existing noncancelable leases for office
space and equipment are as follows:

Demand Note Receivable for $300,000 due July 15, 1999 and $100,000 due May 1,
1999 both with an annual rate of 10.0% paid on a quarterly basis. These

    Interest expense related to the above subordinated liabilities primarily
comprises interest expense in the accompanying statements of operations.

    Exchange membership contributed pursuant to subordination agreements in the
amount of $12,250,000 comprise the remaining subordinated liabilities.

10. SEVERANCE ARRANGEMENTS

    For the years ended December 31, 1997 and 1996, the Partnership entered into
severance arrangements with two of their former members. The Partnership
recorded the full amount of severance upon termination of these individuals in
1997 and 1996.

11. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

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

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

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

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

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Partners of
LaBranche & Co.:

    We have audited the accompanying statements of financial condition of
LaBranche & Co. (a New York limited partnership) as of December 31, 1998 and
1997, and the related statements of operations, changes in partners' capital and
cash flows for the three years in the period ended December 31, 1998. These
financial statements are the responsibility of the partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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


    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of LaBranche & Co. as of
December 31, 1998 and 1997, and the results of its operations and its cash flows
for the three years in the period ended December 31, 1998 in conformity with
generally accepted accounting principles.

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

INTANGIBLE ASSETS

    Intangible assets are soley comprised of goodwill. Goodwill is being
amortized on a straight-line basis over 15 years. Subsequent to its acquisition,
LaBranche continually evaluates whether later events and circumstances have
occurred that indicate the remaining estimated useful life may warrant revision
or that the remaining balance may not be recoverable. When factors indicate that
intangible assets should be evaluated for possible impairment, LaBranche uses an
estimate of undiscounted net income over the remaining life in measuring whether
the assets are recoverable.

EXCHANGE MEMBERSHIPS

    Exchange memberships owned by LaBranche are carried at cost.

    Certain members of LaBranche have contributed the use of 10 memberships on
the NYSE to LaBranche. These memberships are subordinated to claims of general
creditors and are carried at market value with a corresponding amount recorded
in subordinated liabilities. Lease payments are paid by LaBranche to certain
managing directors for the use of the exchange memberships at a rate management
believes is commensurate with the rent paid to nonaffiliated parties for the use
of their exchange memberships.

3. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
CASH AND CASH EQUIVALENTS

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

SECURITIES TRANSACTIONS


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


DEPRECIATION AND AMORTIZATION

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

COLLATERALIZED FINANCING TRANSACTIONS

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

COLLATERAL

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

MANAGING DIRECTORS' COMPENSATION

    LaBranche pays out substantially all of its earnings as compensation expense
to its managing directors.

5. TAXES

    LaBranche is not subject to federal or state income taxes. Such taxes, if
any, are the responsibility of the individual members. LaBranche is subject to
the New York City Unincorporated Business Tax.

6. CAPITAL AND NET LIQUID ASSET REQUIREMENTS

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


    As of June 30, 1999 (unaudited) and as of December 31, 1998, LaBranche's net
capital, as defined under SEC Rule 15c3-1, was $99,993,833 and $86,545,533,
respectively, and exceeded minimum requirements by $96,820,130 and $85,169,019,
respectively. LaBranche's aggregate indebtedness to net capital ratio was .48 to
1 and .42 to 1, respectively.


    The NYSE also requires members registered as regular specialists to
establish that they can meet, with their own net liquid assets, a minimum dollar
amount which shall be the greater of $1,000,000 or 25% of their position
requirement ("Rule 104.2"). In 1998, due to the concentration of LaBranche's
specialist book, the NYSE mandated the firm to maintain minimum net liquid
assets of the greater of 120% of the LaBranche's Rule 104.2 position
requirement, or $90.0 million, adjusted by the amount of the position
requirement for any new stock allocations. The position requirement is the
ability to assume positions in stocks in which they are registered of 30,000
shares of each S&P 500 common stock, 22,500 shares in all other common stocks,
4,500 shares in each convertible preferred stock and 1,800 shares in each
nonconvertible preferred stock. The term "net liquid assets" for a specialist
who also engages in transactions other than specialist activities is based upon
its excess net capital determined in accordance with SEC Rule 15c3-1.

    As of June 30, 1999 (unaudited) and as of December 31, 1998, LaBranche's
NYSE minimum required dollar amount of net liquid assets, as defined, was $91.5
million and $90.6 million, respectively, compared to actual net liquid assets,
as defined, of $116,251,755 and $103,134,594, respectively.

7. ACQUISITIONS

    The acquisitions of the specialist operations described below were accounted
for under the purchase method of accounting. The purchase price of the
acquisitions have been pushed down and reflected in LaBranche's financial
statements. The purchase price associated with each acquisition consisted of
general partnership and limited partnership interests issued to new members
admitted into LaB and new partners admitted into LaBranche. Such partnership
interests were valued based upon an independent appraisal. Excess purchase price
over fair value of net assets acquired has been allocated to goodwill.

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

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


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


8. COMMITMENTS

    During 1998, LaBranche secured a $75.0 million committed line of credit with
The Bank of New York. The agreement matured on June 25, 1999. In June 1999, the
Partnership amended and extended the committed line of credit to $100.0 million
through June 23, 2000 (unaudited). In addition, LaBranche has outstanding letter
of credit agreements with U.S. Trust aggregating approximately $1,581,000. Such
letter of credit agreements are collateralized with U.S. Trust by a Treasury
bill with a face value of $1.5 million and a cash balance of approximately
$179,000.

    Minimum rental commitments under existing noncancelable leases for office
space and equipment are as follows:

<TABLE>
<S>                                                               <C>
Year ending December 31:
1999............................................................  $ 684,000
2000............................................................    468,000
2001............................................................    540,000

2003............................................................    540,000
Thereafter......................................................  2,304,000
</TABLE>

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

9. SUBORDINATED LIABILITIES

    LaBranche has subordinated indebtedness agreements approved by the NYSE for
inclusion as net capital, as defined. Interest is payable quarterly at various
annual rates. Eleven of the agreements representing $11,473,000 mature within
the last six months of 1999, and the remaining four agreements representing
$1,200,000 mature within the first six months of 2000. These agreements all have
automatic rollover provisions as long as at least six months' notice is given by
the lender.

    Seven agreements representing $20,000,000 mature on September 15, 2002 with
an annual rate of 8.17% paid on a quarterly basis. Five agreements representing
$15,000,000 mature on June 3, 2008 with an annual rate of 7.69% paid on a
quarterly basis. These notes are senior to all other subordinated notes.

    LaBranche entered into a subordinated liability related to a Secured Demand
Note Receivable for $300,000 due July 15, 1999 and $100,000 due May 1, 1999,
both with an annual rate of 10.0% paid on, a quarterly basis. These agreements
have automatic rollover provisions as long as at least seven months' notice is
given by the lender.

    Interest expense related to the subordinated liabilities comprises interest
expense in the accompanying statements of operations.

    Exchange memberships contributed pursuant to subordination agreements in the
amount of $12,250,000 comprise the remaining subordinated liabilities.

10. SEVERANCE ARRANGEMENTS

    For the years ended December 31, 1997 and 1996, LaBranche entered into
severance arrangements with two of its former members. LaBranche recorded the
full amount of severance upon termination of these individuals in 1997 and 1996.

11. DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

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

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

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

12. FINANCIAL INSTRUMENTS WITH CONCENTRATION OF CREDIT AND OFF-BALANCE SHEET
    RISK (CONTINUED)
    LaBranche enters into collateralized financing agreements in which it
extends short-term credit to major financial institutions. LaBranche 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.

                         NOTES TO FINANCIAL STATEMENTS

(1) Accounting policies followed by the Firm:

        As of December 1, 1995, the firm changed from a limited partnership
    (L.P.) to a limited liability company (LLC)

        Security transactions are recorded on a trade date basis.

        The inventory of securities in the firm's specialist trading account was
    valued under the last in first out, (LIFO) method of valuation until
    November 30, 1993. Thereafter, the securities inventory is valued at market.

        Federal, State and City income taxes have not been provided for since
    each member is individually liable for his own tax payments. The firm is
    liable for New York City Unincorporated Business Tax and has filed returns
    and paid the tax to November 30, 1998.

        The company's business operations were "merged" into LaBranche & Co. as
    of the close of business on June 30, 1998. At that time the Specialist
    securities, (long and short), and four memberships were transferred to
    LaBranche & Co. All other assets and liabilities were retained by Fowler,
    Rosenau & Geary, LLC

(2) In addition to the three New York Stock Exchange memberships, the use of
    which is contributed to the parternship, the firm holds four other
    memberships subject to ABC agreements. An ABC agreement is an agreement
    under which a membership is held in the name of an individual affiliated
    with the broker-dealer and typically the purchase of the seat is financed by
    the broker-dealer. An ABC agreement provides that if the affiliated person
    leaves the broker-dealer, he or she can retain title to the membership if he
    or she pays the broker-dealer the replacement value of the membership or the
    sales proceeds thereof; otherwise the broker-dealer will be entitled to
    transfer title to another affiliated individual.

(3) The investment in clearing broker Murphey, Marseilles, Smith & Nammack, Inc.
    became worthless in December, 1996 and was written off as a loss in the year
    ended November 30, 1997.

(4) The Deposit and rent security is comprised of:

(5) Off Balance Sheet Risk -- the firm is subject to the risks of fluctuation in
    the value of its long and short positions, which positions it is required to
    take as part of its functioning as a NYSE specialist.

the corporation or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
cause to believe his conduct was unlawful.

    Section 145(b) of the DGCL provides that a Delaware corporation may
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he
acted in any of the capacities set forth above, against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection with the
defense or settlement of such action or suit if he acted under similar
standards, except that no indemnification may be made in respect of any claim,
issue or matter as to which such person shall have been adjudged to be liable to
the corporation unless and only to the extent that the court in which such
action or suit was brought shall determine that despite the adjudication of
liability, such person is fairly and reasonably entitled to be indemnified for
such expenses which the court shall deem proper.

    Section 145 of the DGCL further provides that to the extent a director or
officer of a corporation has been successful in the defense of any action, suit
or proceeding referred to in subsections (a) and (b) or in the defense of any
claim, issue or matter therein, he shall be indemnified against expenses
actually and reasonably incurred by him in connection therewith; that
indemnification provided for by Section 145 shall not be deemed exclusive of any
other rights to which the indemnified party may be

                                      II-1
<PAGE>
entitled; and that the corporation may purchase and maintain insurance on behalf
of any person who is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or enterprise,
against any liability asserted against him or incurred by him in any such
capacity or arising out of his status as such whether or not the corporation
would have the power to indemnify him against such liabilities under such
Section 145.

    Section 102(b)(7) of the DGCL provides that a certificate of incorporation
may contain a provision eliminating or limiting the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director provided that such provision shall not eliminate
or limit the liability of a director: (i) for any breach of the director's duty
of loyalty to the corporation or its stockholders; (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law; (iii) under Section 174 of the DGCL; or (iv) for any transaction from
which the director derived an improper personal benefit.

    Article Tenth of the certificate of incorporation of LaBranche & Co Inc.
(the "Company"), states that to the fullest extent permitted by the DGCL, no
director of the Company shall be personally liable to the Company, any of its
stockholders or any other person or entity for monetary damages for breach of
fiduciary duty owed to the Company, its stockholders or such other person or
entity owing to such director's position as a director of the Company.

    Article Eleventh of the Company's certificate of incorporation, contains
substantially the same provisions for indemnification as those contained in
Section 145 of the DGCL.

    The Company intends to enter into indemnification agreements with its
current directors and executive officers. The Company intends to insure its
directors and officers against losses arising from any claim against them as
such for wrongful acts or omission, subject to certain limitations.

    Under Section   of the underwriting agreement, the underwriters are
obligated, under certain circumstances, to indemnify officers, directors and
controlling persons of the Company against certain liabilities, including
liabilities under the Securities Act of 1933. Reference is made to the form of
underwriting agreement filed as Exhibit 1.1 hereto.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES


    As part of the Reorganization and Related Transactions, LaBranche & Co Inc.
will issue: (i) an aggregate of 35,375,000 shares of the Company's common stock,
par value $.01 per share (the "Common Stock"), to certain limited partners of
LaBranche & Co. and all of the members of LaB Investing Co. L.L.C. and (ii) a
$16.4 million of subordinated indebtedness (collectively, the "Reorganization
Securities"). Also immediately prior to this offering, the Company will make
awards of stock options and restricted stock units to certain of its employees.
Since 1996, the Company sold (i) $20.0 million aggregate principal amount of
8.17% subordinated notes; (ii) $15.0 million aggregate principal amount of 7.69%
subordinated notes; and (iii) $15.3 million aggregate principal amount of 10.0%
subordinated notes (collectively, the "Notes"). The offering and sale of the
Reorganization Securities will not be registered under the Securities Act of
1933, as amended (the "Securities Act"), because they will have been offered and
sold in transactions exempt form registration under the Securities Act pursuant
to Section 4(2). The offering and sale of the Notes were not registered under
the Securities Act because they were offered and sold in transactions exempt
from registration under the Securities Act pursuant to Section 4(2). The
employee awards will not be registered under the Securities Act because the
awards will not involve an offer or sale for purposes of Section 2(a)(3) of the
Securities Act.

ITEM 17. UNDERTAKINGS


    Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Act"), may be permitted to directors, officers, and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.


    The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

    The undersigned Registrant hereby undertakes that:

    (1)  For purposes of determining any liability under the Securities Act of
1933, as amended, the information omitted from the form of prospectus filed as
part of this Registration Statement in reliance upon Rule 430A and contained in
a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4)
or 497(h) under the Securities Act shall be deemed to be part of this
Registration Statement as of the time it was declared effective.

    (2)  For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         1. REPRESENTATIONS AND WARRANTIES. The Company represents and warrants

                  (a) The Company has prepared and filed with the Commission a
         registration statement (file number 333-81079) on Form S-1, including
         a related preliminary prospectus, for registration under the Act of the
         offering and sale of the Securities. The Company may have filed one or
         more amendments thereto, including a related preliminary prospectus,
         each of which has previously been furnished to you. The Company will
         next file with the Commission either (1) prior to the Effective Date of
         such registration statement, a further amendment to such registration
         statement (including the form of final prospectus) or (2) after the
         Effective Date of such registration statement, a final prospectus in
         accordance with Rules 430A and 424(b). In the case of clause (2), the
         Company has included in such registration statement, as amended at the
         Effective Date, all information (other than Rule 430A Information)
         required by the Act and the rules thereunder to be included in such
         registration statement and the Prospectus. As filed, such amendment and
         form of final prospectus, or such final prospectus, shall contain all
         Rule 430A Information, together with all other such required
         information, and, except to the extent the Representatives shall agree
         in writing to a modification, shall be in all substantive respects in
         the form furnished to you prior to the Execution Time or, to the extent
         not completed at the Execution Time, shall contain only such specific
         additional information and other changes (beyond that contained in the
         latest Preliminary Prospectus) as the Company has advised you, prior to
         the Execution Time, will be included or made therein;

                  (b) On the Effective Date, the Registration Statement did or
         will, and when the Prospectus is first filed (if required) in
         accordance with Rule 424(b) and on the Closing Date (as defined herein)
         and on any date on which Option Securities are purchased, if such date
         is not the Closing Date (a "SETTLEMENT DATE"), the Prospectus (and any
         supplements thereto) will, comply in all material respects with the
         applicable requirements of the Act and the rules thereunder; on the
         Effective Date and at the


                                       2
<PAGE>

         Execution Time, the Registration Statement did not or will not contain
         any untrue statement of a material fact or omit to state any material
         fact required to be stated therein or necessary in order to make the
         statements therein not misleading; and, on the Effective Date, the
         Prospectus, if not filed pursuant to Rule 424(b), will not, and on the
         date of any filing pursuant to Rule 424(b) and on the Closing Date and
         any settlement date, the Prospectus (together with any supplement
         thereto) will not, include any untrue statement of a material fact or
         omit to state a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading; PROVIDED, HOWEVER, that the Company makes no
         representations or warranties as to the information contained in or
         omitted from the Registration Statement, or the Prospectus (or any
         supplement thereto) in reliance upon and in conformity with information
         furnished in writing to the Company by or on behalf of any Underwriter
         through the Representatives specifically for inclusion in the
         Registration Statement or the Prospectus (or any supplement thereto);

                  (c) The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the
         jurisdiction in which it is chartered or organized with full corporate
         power and authority to own or lease, as the case may be, and to operate
         its properties and conduct its business as described in the Prospectus,
         and is duly qualified to do business as a foreign corporation and is in
         good standing under the laws of each jurisdiction which requires such
         qualification; each of LaBCo. and LaBLLC has been duly organized and is
         validly existing as a limited partnership and a limited liability
         company, respectively, in good standing under the laws of the

                  (l) The consolidated historical financial statements and
         schedules of the Company and its consolidated Subsidiaries included in
         the Prospectus and the Registration Statement present fairly in all
         material respects the financial condition, results of operations and
         cash flows of the Company as of the dates and for the periods
         indicated, comply as to form with the applicable accounting
         requirements of the Act and have been prepared in conformity with
         generally accepted accounting principles applied on a consistent basis
         throughout the periods involved (except as otherwise noted therein).

         "Summary--Summary Historical Consolidated Financial Data" and "Selected
         Historical Consolidated Financial Data" in the Prospectus and
         Registration Statement fairly present, on the basis stated in the
         Prospectus and the Registration Statement, the information included

         reasonable basis for presenting the significant effects directly
         attributable to the transactions and events described therein, the
         related pro forma adjustments give appropriate effect to those
         assumptions, and the pro forma adjustments reflect the proper
         application of those adjustments to the historical financial statement
         amounts in the pro forma financial statements included in the
         Prospectus and the Registration Statement. The pro forma financial
         statements included in the Prospectus and the Registration Statement
         comply as to form in all material respects with the applicable
         accounting requirements of Regulation S-X under the Act and the pro
         forma adjustments have been properly applied to the historical amounts
         in the compilation of those statements;

                  (m) There are no pending actions, suits or proceedings by or
         before any court or governmental agency, authority or body or any
         arbitrator involving the Company or any of its Subsidiaries is a party
         or its or their property is subject of a character required to be
         disclosed in the Registration Statement which is not adequately
         disclosed in the Prospectus; and, to the best of the Company's
         knowledge, no such actions, suits or proceedings are threatened or
         contemplated by any court or governmental agency, authority or body or
         threatened by others;

                  (n) Each of the Company and each of its Subsidiaries owns or
         leases all such properties as are necessary to the conduct of its
         operations as presently conducted, and all of the property held under
         lease by the Company or its Subsidiaries is held by it under valid,
         subsisting and enforceable leases, except as the enforcement thereof
         may be limited by bankruptcy, insolvency, or similar laws affecting the
         enforcement of creditors' rights generally and subject to applicability
         of general principles of equity;

                  (o) Neither the Company nor any Subsidiary is in violation or
         default of (i) any provision of its charter or bylaws, (ii) the terms
         of any indenture, contract, lease, mortgage, deed of trust, note
         agreement, loan agreement or other agreement, obligation, condition,
         covenant or instrument to which it is a party or bound or to which its
         property is subject, or (iii) any statute, law, rule, regulation,
         judgment, order or decree of any court, regulatory body, administrative
         agency, governmental body, arbitrator or other authority having
         jurisdiction over the Company or such Subsidiary or any of its
         properties, as applicable;

         insurers of recognized financial responsibility against such losses and
         risks and in such amounts as are prudent and customary in the

         fidelity or surety bonds] insuring the Company or any of its
         Subsidiaries or their respective businesses, assets, employees,
         officers and directors are in full force and effect; the Company and
         its Subsidiaries are in compliance with the terms of such policies and
         instruments in all material respects; and there are no claims by the
         Company or any of its Subsidiaries under any such policy or instrument
         as to which any insurance company is denying liability or defending
         under a reservation of rights clause; neither the Company nor any such
         Subsidiary has been refused any insurance coverage sought or applied
         for; and neither the Company nor any such Subsidiary has any reason to
         believe that it will not be able to renew its existing insurance
         coverage as and when such coverage expires or to obtain similar
         coverage from similar insurers as may be necessary to continue its
         business at a cost that would not have a material adverse effect on the
         condition (financial or otherwise), prospects, earnings, business or
         properties of the Company and its Subsidiaries, taken as a whole,
         whether or not arising from transactions in the ordinary course of
         business, except as set forth in or contemplated in the Prospectus
         (exclusive of any supplement thereto);

                  (t) No Subsidiary of the Company is currently prohibited,
         directly or indirectly, from making any distribution in respect of its
         membership or partnership interests, as the case may be, from repaying
         to the Company any loans or advances to such Subsidiary from the
         Company or from transferring any of such Subsidiary's property or
         assets to the Company or any other Subsidiary of the Company, except as
         described in or contemplated by the Prospectus;

                  (u) The Company and its Subsidiaries have such concessions,
         permits, licenses, consents, exemptions, franchises, authorizations,
         orders, registrations, qualifications and other approvals (each, an

         Federal state and foreign governments, governmental or regulatory
         authorities and


                                       6

         self-regulatory organizations and all courts and other tribunals, as
         are necessary to consummate the Reorganization Transactions and the
         Related Transactions. Each such Authorization is valid and in full
         force and effect and the Company and each of its Subsidiaries is in
         compliance with all of the terms and conditions thereof; and no event
         has occurred (including, without limitation, the receipt of any notice
         from any authority or governing body) which allows or, after notice or
         lapse of time or both, would allow, revocation, suspension or
         termination of any such Authorization or results or, after notice or
         lapse of time or both, would result in any other impairment of the
         rights of the holder of any such Authorization; and other than as
         disclosed in the Prospectus, such Authorizations contain no
         restrictions that are materially more burdensome than those imposed on
         LaBCo. and LaBLLC immediately prior to the consummation of the
         Reorganization Transactions;

                  (v) The Company and its Subsidiaries possess all

         good standing of each Federal, state or foreign exchange, board of
         trade, clearing house or association and self-regulatory or similar

         described in the Prospectus;

                  (w) The Company and each of its Subsidiaries maintain a system

         assurance that (i) transactions are executed in accordance with
         management's general or specific authorizations; (ii) transactions are
         recorded as necessary to permit preparation of financial statements in
         conformity with generally accepted accounting principles and to
         maintain asset accountability; (iii) access to assets is permitted only
         in accordance with management's general or specific authorization; and
         (iv) the recorded accountability for assets is compared with the
         existing assets at reasonable intervals and appropriate action is taken
         with respect to any differences;

                  (x) The Company has not taken, directly or indirectly, any
         action designed to or which has constituted or which might reasonably
         be expected to cause or result, under the Exchange Act or otherwise, in
         stabilization or manipulation of the price of any security of the
         Company to facilitate the sale or resale of the Securities;

                  (y) Each of the Company and its Subsidiaries has fulfilled its
         obligations, if any, under the minimum funding standards of Section 302

         such regulations and published interpretations) in which employees of
         the Company and its Subsidiaries are eligible to participate and each
         such plan is in compliance in all material respects with the presently

         unpaid liability to the Pension Benefit Guaranty Corporation (other
         than for the payment of premiums in the ordinary course) or to any such
         plan under Title IV of ERISA;

         of the Reorganization Transactions and the Related Transactions will
         not (i) conflict with or constitute a breach of any of the terms or
         provisions of, or a default under, (A) the organizational documents of
         the Company, (B) any of the organizational documents of either of the
         Subsidiaries, or (C) any indenture, loan agreement, mortgage, lease or

         violate or conflict with any applicable law or any rule, regulation,
         judgment, order or decree of any government or court or any
         governmental body or agency having jurisdiction over the Company or any
         of its Subsidiaries or any of their respective properties;

                  4. OFFERING BY UNDERWRITERS. It is understood that the several
Underwriters propose to offer the Securities for sale to the public as set forth
in the Prospectus.

                  5. AGREEMENTS. The Company agrees with the several
Underwriters that:

                  (a) The Company will use its best efforts to cause the
         Registration Statement, if not effective at the Execution Time, and any
         amendment thereof, to become effective. Prior to the termination of the
         offering of the Securities, the Company will not file any amendment of
         the Registration Statement or supplement to the Prospectus or any Rule
         462(b) Registration Statement unless the Company has furnished you a
         copy for your review prior to filing and will not file any such
         proposed amendment or supplement to which you reasonably object.
         Subject to the foregoing sentence, if the Registration Statement has
         become or becomes effective pursuant to Rule 430A, or filing of the
         Prospectus is otherwise required under Rule 424(b), the Company will
         cause the Prospectus, properly completed, and any supplement thereto to
         be filed with the Commission pursuant to the applicable paragraph of
         Rule 424(b) within the time period


                                       10
<PAGE>

         prescribed and will provide evidence satisfactory to the
         Representatives of such timely filing. The Company will promptly advise
         the Representatives (1) when the Registration Statement, if not
         effective at the Execution Time, shall have become effective, (2) when
         the Prospectus, and any supplement thereto, shall have been filed (if
         required) with the Commission pursuant to Rule 424(b) or when any Rule
         462(b) Registration Statement shall have been filed with the
         Commission, (3) when, prior to termination of the offering of the
         Securities, any amendment to the Registration Statement shall have been
         filed or become effective, (4) of any request by the Commission or its
         staff for any amendment of the Registration Statement, or any Rule
         462(b) Registration Statement, or for any supplement to the Prospectus
         or for any additional information, (5) of the issuance by the
         Commission of any stop order suspending the effectiveness of the
         Registration Statement or the institution or threatening of any
         proceeding for that purpose and (6) of the receipt by the Company of
         any notification with respect to the suspension of the qualification of
         the Securities for sale in any jurisdiction or the institution or
         threatening of any proceeding for such purpose. The Company will use
         its best efforts to prevent the issuance of any such stop order or the
         suspension of any such qualification and, if issued, to obtain as soon
         as possible the withdrawal thereof.

                  (b) If, at any time when a prospectus relating to the
         Securities is required to be delivered under the Act, any event occurs
         as a result of which the Prospectus as then supplemented would include
         any untrue statement of a material fact or omit to state any material
         fact necessary to make the statements therein in the light of the
         circumstances under which they were made not misleading, or if it shall
         be necessary to amend the Registration Statement or supplement the
         Prospectus to comply with the Act or the rules thereunder, the Company
         promptly will (1) notify the Representatives of any such event, (2)
         prepare and file with the Commission, subject to the second sentence of
         paragraph (a) of this Section 5, an amendment or supplement which will
         correct such statement or omission or effect such compliance; and (3)
         supply any supplemented Prospectus to you in such quantities as you may
         reasonably request.

                  (c) As soon as practicable, the Company will make generally
         available to its security holders and to the Representatives an
         earnings statement or statements of the Company and its Subsidiaries
         which will satisfy the provisions of Section 11(a) of the Act and Rule
         158 under the Act.

                  (d) The Company will furnish to the Representatives and
         counsel for the Underwriters signed copies of the Registration
         Statement (including exhibits thereto) and to each other Underwriter a
         copy of the Registration Statement (without exhibits thereto) and, so
         long as delivery of a prospectus by an Underwriter or dealer may be
         required by the Act, as many copies of each Preliminary Prospectus and
         the Prospectus and any supplement thereto as the Representatives may
         reasonably request.

                  (e) The Company will arrange, if necessary, for the
         qualification of the Securities for sale under the laws of such
         jurisdictions as the Representatives may designate and will maintain
         such qualifications in effect so long as required for the distribution
         of the Securities; provided that in no event shall the Company be
         obligated to qualify to do business in any jurisdiction where it is not
         now so qualified or to take any action that


                                       11
<PAGE>

         would subject it to service of process in suits, other than those
         arising out of the offering or sale of the Securities, in any
         jurisdiction where it is not now so subject.

                  (f) The Company will not, without the prior written consent of
         Salomon Smith Barney Inc., offer, sell, contract to sell, pledge, or
         otherwise dispose of, (or enter into any transaction which is designed
         to, or might reasonably be expected to, result in the disposition
         (whether by actual disposition or effective economic disposition due to
         cash settlement or otherwise) by the Company or any affiliate of the
         Company or any person in privity with the Company or any affiliate of
         the Company) directly or indirectly, including the filing (or
         participation in the filing) of a registration statement with the
         Commission in respect of, or establish or increase a put equivalent
         position or liquidate or decrease a call equivalent position within the
         meaning of Section 16 of the Exchange Act, any other shares of Common
         Stock or any securities convertible into, or exercisable, or
         exchangeable for, shares of Common Stock; or publicly announce an
         intention to effect any such transaction, for a period of 180 days
         after the date of the Underwriting Agreement, PROVIDED, HOWEVER, that
         the Company may issue and sell Common Stock pursuant to any employee
         stock option plan, stock ownership plan or dividend reinvestment plan
         of the Company in effect at the Execution Time and the Company may
         issue Common Stock issuable upon the conversion of securities or the
         exercise of warrants outstanding at the Execution Time.

                  (g) The Company will not take, directly or indirectly, any
         action designed to or which has constituted or which might reasonably
         be expected to cause or result, under the Exchange Act or otherwise, in
         stabilization or manipulation of the price of any security of the
         Company to facilitate the sale or resale of the Securities.

                  (h) The Company agrees to pay the costs and expenses relating
         to the following matters: (i) the preparation, printing or reproduction
         and filing with the Commission of the Registration Statement (including
         financial statements and exhibits thereto), each Preliminary

         registration of the Securities under the Exchange Act and the listing
         of the Securities on the New York Stock Exchange; (vi) any registration

                  applicable self-regulatory organizations, as are necessary to
                  consummate the Reorganization Transactions and the Related
                  Transactions. Each such Authorization is valid and in full
                  force and effect; and, to the best of such counsel's
                  knowledge, no event has occurred that would reasonably be
                  expected to result in the revocation, suspension or
                  termination of any such Authorization or results or, after
                  notice or lapse of time or both, would reasonably be expected
                  to result in any other material impairment of the rights of
                  the holder of any such Authorization; and other than as
                  disclosed in the Prospectus, such Authorizations contain no
                  restrictions that are materially more burdensome than those
                  imposed on LaBCo. or LaBLLC immediately prior to the
                  consummation of the Reorganization Transactions;

                           (xi) all stockholder, partnership and limited
                  liability company member approvals necessary for LaBInc.,
                  LaBCo. and LaBLLC to consummate the

                  Reorganization Transactions and the Related Transactions have
                  been obtained and are in full force and effect. The
                  consummation of the Reorganization Transactions and the
                  Related Transactions will not (i) conflict with or constitute
                  a breach of any of the terms or provisions of, or a default
                  under, (A) the organizational documents of LaBInc., (B) the
                  organizational documents of LaBCo. or LaBLLC, or (C) any
                  material indenture, mortgage, deed of trust, loan agreement,
                  or other agreement or instrument known to such counsel to
                  which any of LaBInc., LaBCo. or LaBLLC is a party or by which
                  any of LaBInc., LaBCo. or LaBLLC is bound or to which any of
                  the property or assets of any of LaBInc., LaBCo. or LaBLLC is
                  subject, or (ii) violate or conflict with any statute or any
                  order, rule or regulation known to such counsel of any court
                  or governmental agency or body having jurisdiction over any of
                  LaBInc., LaBCo. or LaBLLC or any of their properties;
                  provided, HOWEVER, that, for the purposes of this paragraph
                  (xi), such counsel need not express any opinion with respect
                  to Federal or state securities laws, other antifraud laws, and
                  fraudulent transfer laws, and, insofar as the consummation of
                  the Reorganization Transactions and Related Transactions are
                  concerned, such counsel need not express any opinion as to
                  bankruptcy, insolvency, reorganization, moratorium and similar
                  laws of general applicability relating to or affecting
                  creditors' rights;

                           (xii) no consent, approval, authorization, filing
                  with or order of any court or governmental agency or body is
                  required in connection with the transactions contemplated
                  herein, except such as have been obtained under the Act and
                  such as may be required under the blue sky laws of any
                  jurisdiction in connection with the purchase and distribution
                  of the Securities by the Underwriters in the manner
                  contemplated in this Agreement and in the Prospectus and such
                  other approvals (specified in such opinion) as have been
                  obtained;

                           (xiii) neither the issue and sale of the Securities,
                  nor the consummation of any other of the transactions herein
                  contemplated nor the fulfillment of the terms hereof will
                  conflict with, result in a breach or violation of or
                  imposition of any lien, charge or encumbrance upon any
                  property or assets of the Company or pursuant to, (i) the
                  charter or by-laws of the Company or the organizational
                  documents of its Subsidiaries, (ii) the terms of any
                  indenture, contract, lease, mortgage, deed of trust, note
                  agreement, loan agreement or other agreement, obligation,
                  condition, covenant or instrument to which the Company or its
                  Subsidiaries is a party or bound or to which its or their
                  property is subject, or (iii) any statute, law, rule,
                  regulation, judgment, order or decree applicable to the
                  Company or its Subsidiaries of any court, regulatory body,
                  administrative agency, governmental body, arbitrator or other
                  authority having jurisdiction over the Company or its
                  Subsidiaries or any of its or their properties;

                           (xiv) neither the Company nor any Subsidiary is in
                  violation or default of (i) any provision of its charter or
                  bylaws, (ii) the terms of any indenture, contract, lease,
                  mortgage, deed of trust, note agreement, loan agreement or
                  other agreement, obligation, condition, covenant or instrument
                  to which it is a party or bound or to which its property is
                  subject, or (iii) any statute, law, rule, regulation,

                  administrative agency, governmental body, arbitrator or other
                  authority having jurisdiction over the Company or such
                  Subsidiary or any of its properties, as applicable;

                           (xv) there are no transfer taxes or other similar
                  fees or charges under Federal law or the laws of any state, or
                  any political subdivision thereof, required to be paid in
                  connection with the execution and delivery of this Agreement
                  or the issuance by the Company or sale by the Company of the
                  Securities;

                           (xvi) no Subsidiary of the Company is currently
                  prohibited, directly or indirectly, from making any
                  distribution in respect of its membership or partnership
                  interests, as the case may be, from repaying to the Company
                  any loans or advances to such Subsidiary from the Company or
                  from transferring any of such Subsidiary's property or assets
                  to the Company or any other Subsidiary of the Company, except
                  as described in or contemplated by the Prospectus;

                           (xvii) the Company and its Subsidiaries have such
                  Authorizations of, and have made all filings with and notices
                  to, all Federal state and foreign governments, governmental or
                  regulatory authorities and self-regulatory organizations and
                  all courts and other tribunals, as are necessary to consummate
                  the Reorganization Transactions and the Related Transactions.
                  Each such Authorization is valid and in full force and effect
                  and the Company and each of its Subsidiaries is in compliance
                  with all of the terms and conditions thereof; and no event has
                  occurred (including, without limitation, the receipt of any
                  notice from any authority or governing body) which allows or,
                  after notice or lapse of time or both, would allow,
                  revocation, suspension or termination of any such
                  Authorization or results or, after notice or lapse of time or
                  both, would result in any other impairment of the rights of
                  the holder of any such Authorization; and other than as
                  disclosed in the Prospectus, such Authorizations contain no
                  restrictions that are materially more burdensome than those
                  imposed on LaBCo. and LaBLLC immediately prior to the
                  consummation of the Reorganization Transactions;

                           (xviii) the Company and its Subsidiaries possess all
                  Authorizations issued by the appropriate Federal, state and
                  foreign governments, governmental or regulatory authorities,
                  self-regulatory organizations and all courts or other
                  tribunals, and are members in good standing of each Federal,
                  state or foreign exchange, board of trade, clearing house or
                  association and self-regulatory or similar organization
                  necessary to conduct their respective businesses as described
                  in the Prospectus;

                           (xix) all stockholder, partnership and limited
                  liability company member approvals necessary for the Company
                  and each Subsidiary to consummate the Reorganization
                  Transactions and the Related Transactions have been obtained
                  and are in full force and effect. The consummation of the
                  Reorganization Transactions and the Related Transactions will
                  not (i) conflict with or constitute a breach of any of the
                  terms or provisions of, or a default under, (A) the


                                       17
<PAGE>

                  organizational documents of the Company, (B) any of the
                  organizational documents of either of the Subsidiaries, or (C)
                  any indenture, loan agreement, mortgage, lease or other
                  agreement or instrument to which the Company or any of its
                  Subsidiaries is a party or by which the Company or any of its
                  Subsidiaries or any of their respective properties is bound,
                  or (ii) violate or conflict with any applicable law or any
                  rule, regulation, judgment, order or decree of any government
                  or court or any governmental body or agency having
                  jurisdiction over the Company or any of its Subsidiaries or
                  any of their respective properties;

                           (xx) it is not necessary in connection with the
                  grant, issuance, offer, sale and delivery of the securities to
                  be issued by the Company pursuant to the Reorganization
                  Transactions, to register any such securities under the Act,
                  or to qualify any indenture under the Trust Indenture Act of
                  1939, as amended;

                           (xxi) LaBCo. is registered as a broker-dealer with
                  the SEC under the Exchange Act and with state securities
                  authorities in each state where LaBCo. is required to be so
                  registered. LaBCo. is a member organization in good standing
                  with the NYSE;

                           (xxii) the consummation of the transactions
                  contemplated by the Reorganization Transactions and the
                  Related Transactions will not violate Regulation T, U or X of
                  the Board of Governors of the Federal Reserve system; and

                           (xxiii) no holders of securities of the Company have
                  any preemptive rights to acquire any securities of the Company
                  or any rights to the registration of such securities under the
                  Registration Statement.

         In rendering such opinion, such counsel may rely (A) as to matters
         involving the application of laws of any jurisdiction other than the
         State of New York or the Federal laws of the United States, to the
         extent they deem proper and specified in such opinion, upon the opinion
         of other counsel of good standing whom they believe to be reliable and
         who are satisfactory to counsel for the Underwriters and (B) as to
         matters of fact, to the extent they deem proper, on certificates of
         responsible officers of the Company and public officials. References to
         the Prospectus in this paragraph (b) include any supplements thereto at
         the Closing Date.

                  (c) The Representatives shall have received from Cleary,
         Gottlieb, Steen & Hamilton, counsel for the Underwriters, such opinion
         or opinions, dated the Closing Date and addressed to the
         Representatives, with respect to the issuance and sale of the
         Securities, the Registration Statement, the Prospectus (together with
         any supplement thereto) and other related matters as the
         Representatives may reasonably require, and the Company shall have
         furnished to such counsel such documents as they request for the
         purpose of enabling them to pass upon such matters.

                  (d) The Company shall have furnished to the Representatives a
         certificate of the Company, signed by the Chairman of the Board and the
         principal financial officer of the


                                       18

         Company, dated the Closing Date, to the effect that the signers of such
         certificate have carefully examined the Registration Statement, the
         Prospectus, any supplements to the Prospectus and this Agreement and
         that:

                           (i) the representations and warranties of the Company
                  in this Agreement are true and correct in all material
                  respects on and as of the Closing Date with the same effect as
                  if made on the Closing Date and the Company has complied with
                  all the agreements and satisfied all the conditions on its
                  part to be performed or satisfied at or prior to the Closing
                  Date;

                           (ii) no stop order suspending the effectiveness of
                  the Registration Statement has been issued and no proceedings
                  for that purpose have been instituted or, to the Company's
                  knowledge, threatened; and

                           (iii) since the date of the most recent financial
                  statements included in the Prospectus (exclusive of any
                  supplement thereto), there has been no material adverse effect
                  on the condition (financial or otherwise), prospects,
                  earnings, business or properties of the Company and its
                  Subsidiaries, taken as a whole, whether or not arising from
                  transactions in the ordinary course of business, except as set
                  forth in or contemplated in the Prospectus (exclusive of any
                  supplement thereto).

                  (e) The Company shall have requested and caused Arthur
         Andersen LLP to have furnished to the Representatives, at the Execution
         Time and at the Closing Date, letters, dated respectively as of the
         Execution Time and as of the Closing Date, in form and substance
         satisfactory to the Representatives, confirming that they are
         independent accountants within the meaning of the Act and the
         applicable rules and regulations adopted by the Commission thereunder
         and that they have performed a review of the unaudited interim
         financial information of the Company for the six-month period ended
         [June 30], 1999, and as at June 30, 1999, in accordance with
         Statement on Auditing Standards No. 71 and stating in effect that:

                           (i) in their opinion the audited financial statements
                  financial statement schedules and pro forma financial
                  statements included in the Registration Statement and the
                  Prospectus and reported on by them comply as to form in all
                  material respects with the applicable accounting requirements
                  of the Act and the related rules and regulations adopted by
                  the Commission;

                           (ii) on the basis of a reading of the latest
                  unaudited financial statements made available by the Company
                  and its Subsidiaries; their limited review, in accordance with
                  standards established under Statement on Auditing Standards
                  No. 71, of the unaudited interim financial information for the
                  six-month period ended June 30, 1999, and as at June 30, 1999,
                  as indicated in their report dated           , 1999; carrying
                  out certain specified procedures (but not an examination in
                  accordance with generally accepted auditing standards) which
                  would not necessarily reveal matters of significance with
                  respect to the comments set forth in such letter; a reading of
                  the minutes of the meetings of the stockholders,

                  directors and Managing Committee LaB LLC; and inquiries of
                  certain officials of the Company who have responsibility
                  for financial and accounting matters of the Company and its
                  Subsidiaries as to transactions and events subsequent to
                  June 30, 1999, nothing came to their attention which caused
                  them to believe that:

                                    (1) any unaudited financial statements
                           included in the Registration Statement and the
                           Prospectus do not comply as to form in all material
                           respects with applicable accounting requirements of
                           the Act and with the related rules and regulations
                           adopted by the Commission with respect to
                           registration statements on Form S-1; and said
                           unaudited financial statements are not in conformity
                           with generally accepted accounting principles applied
                           on a basis substantially consistent with that of the
                           audited financial statements included in the
                           Registration Statement and the Prospectus;

                                    (2) with respect to the period subsequent to
                           June 30, 1999, there were any changes, at a
                           specified date not more than five days prior to the
                           date of the letter, in the long-term indebtedness of
                           the Company and its Subsidiaries or capital stock of

                           capital/stockholders' equity of the Company as
                           compared with the amounts shown on the June 30,
                           1999 consolidated balance sheet included in the
                           Registration Statement and the Prospectus, or for the
                           period from July 1, 1999 to such specified date there
                           were any decreases, as compared with fiscal year in
                           income before limited partners' interest in earnings
                           of subsidiary and provision for income taxes or per
                           share amounts of net income of the Company and its
                           Subsidiaries, except in all instances for changes or
                           decreases set forth in such letter, in which case
                           the letter shall be accompanied by an explanation by
                           the Company as to the significance thereof unless
                           said explanation is not deemed necessary by the
                           Representatives;

                                    (3) the information included in the
                           Registration Statement and Prospectus in response to
                           Regulation S-K, Item 301 (Selected Financial Data),
                           Item 302 (Supplementary Financial Information), Item
                           402 (Executive Compensation) and Item 503(d) (Ratio
                           of Earnings to Fixed Charges) is not in conformity
                           with the applicable disclosure requirements of
                           Regulation S-K; and

                           (iii) they have performed certain other specified
                  procedures as a result of which they determined that certain
                  information of an accounting, financial or statistical nature
                  (which is limited to accounting, financial or statistical
                  information derived from the general accounting records of the
                  Company and its Subsidiaries) set forth in the Registration
                  Statement and the Prospectus, including the information set
                  forth under the captions "Summary--Summary Selected Historical
                  Consolidated Financial Data," "Capitalization," "Selected
                  Historical

                  Consolidated Financial Data" and "Management Discussion and
                  Analysis of Financial Condition and Results of Operations" in
                  the Prospectus, agrees with the accounting records of the
                  Company and its Subsidiaries, excluding any questions of legal
                  interpretation.

                  References to the Prospectus in this paragraph (e) include any
                  supplement thereto at the date of the letter.

                  The Company shall have received from Arthur Andersen LLP (and
         furnished to the Representatives) a report with respect to a review of
         unaudited interim financial information of the Company for the eight
         quarters ending December 31, 1998, in accordance with Statement on
         Auditing Standards No. 71.

                  The Company shall have received from Arthur Andersen LLP (and
furnished to the Representatives) an examination report with respect to
Management's Discussion and Analysis of Financial Condition and Results of
Operations of the Company for the three fiscal years ending December 31, 1998,
and a review report with respect to Management's Discussion and Analysis of
Financial Condition and Results of Operations of the Company for the six-month
period ending June 30, 1999, in respect of which a Statement on Auditing
Standards No. 71 review has been performed and the corresponding period for the
prior fiscal year, each in accordance with Statement on Standards for
Attestation Engagements No. 8 issued by the Auditing Standards Board of the
American Institute of Certified Public Accountants, and such examination report
shall be included in the Registration Statement.

                  (f) The Company shall have caused Sugarman & Thrope, P.C. to
have furnished to the Representatives letters, dated respectively as of the
Execution Time and as of the Closing Date, in form and substance reasonably
satisfactory to the Representatives, confirming that they are independent
accountants within the meaning of the Act and the applicable published rules and
regulations adopted by the Commission thereunder and stating in effect that:

                           (i) in their opinion the audited financial statements
                  and financial statement schedules included in the Registration
                  Statement and the Prospectus and reported on by them comply in
                  form in all material respects with the applicable accounting
                  requirements of the Act and the related published rules and
                  regulations;

                           (ii) on the basis of a reading of the latest
                  unaudited financial statements made available by Fowler; their
                  limited review in accordance with standards established by the
                  American Institute of Certified Public Accountants of the
                  unaudited interim financial information for the seven-month
                  period ended June 30, 1998 and as at June 30, 1998, as
                  indicated in their report dated January 20, 1999; carrying out
                  certain specified procedures (but not an examination in
                  accordance with generally accepted auditing standards) which
                  would not necessarily reveal matters of significance with
                  respect to the comments set forth in such letter; and
                  inquiries of certain officials of Fowler, who have
                  responsibility for financial and accounting matters of Fowler,
                  as to transactions and events


                                       21
<PAGE>

                  subsequent to November 30, 1997, nothing came to their
                  attention which caused them to believe that:

                                    (A) any unaudited financial statements of
                           Fowler, included in the Registration Statement and
                           the Prospectus do not comply in form in all material
                           respects with applicable accounting requirements of
                           the Act and with the published rules and regulations
                           of the Commission with respect to registration
                           statements on Form S-1; and said unaudited financial
                           statements are not in conformity with generally
                           accepted accounting principals applied on a basis
                           substantially consistent with that of the audited
                           financial statements included in the Registration
                           Statement and the Prospectus; or

                                    (B) with respect to the period subsequent to
                           June 30, 1998, there were any changes, at a specified
                           date not more than five business days prior to the
                           date of the letter, in the total liabilities of
                           Fowler, or decreases in inventory of specialist
                           stocks or members' capital of Fowler as compared with
                           the amounts shown on the June 30, 1998 consolidated
                           balance sheet included in the Registration Statement
                           and the Prospectus, or for the period from July 1,
                           1998 to such specified date there were any decreases,
                           as compared with the corresponding period in the
                           preceding fiscal year, in net income of Fowler except
                           in all instances for changes or decreases set
                           forth in such letter, in which case the letter shall
                           be accompanied by an explanation by the Company as to
                           the significance thereof unless said explanation is
                           not deemed necessary by the Representatives; and

                           (iii) they have performed certain other specified
                  procedures as a result of which they determined that certain
                  information of an accounting, financial or statistical nature
                  (which is limited to accounting, financial or statistical
                  information derived from the general accounting records of the
                  Company and its Subsidiaries) set forth in the Registration
                  Statement and the Prospectus agrees with the accounting
                  records of Fowler excluding any questions of legal
                  interpretation.

                  References to the Prospectus in this paragraph (f) include any
supplement thereto at the date of the letter.

                  (g) Subsequent to the Execution Time or, if earlier, the dates
as of which information is given in the Registration Statement (exclusive of any
amendment thereof) and the Prospectus (exclusive of any supplement thereto),
there shall not have been (i) any change or decrease specified in the letter or
letters referred to in paragraph (e) of this Section 6 or (ii) any change, or
any development involving a prospective change, in or affecting the condition
(financial or otherwise), earnings, business or properties of the Company and
its Subsidiaries taken as a whole, whether or not arising from transactions in
the ordinary course of business, except as set forth in or contemplated in the
Prospectus (exclusive of any supplement thereto) the effect of which, in any
case referred to in clause (i) or (ii) above, is, in the sole judgment of the


                                       22
<PAGE>

Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the Securities as
contemplated by the Registration Statement (exclusive of any amendment thereof)
and the Prospectus (exclusive of any supplement thereto).

                  (h) Prior to the Closing Date, the Company shall have
furnished to the Representatives such further information, certificates and
documents as the Representatives may reasonably request.

                  (i) The Securities shall have been listed and admitted and
authorized for trading on the New York Stock Exchange, and satisfactory evidence
of such actions shall have been provided to the Representatives.

                  (j) At the Execution Time, the Company shall have furnished to
the Representatives a letter substantially in the form of Exhibit A hereto from
each of the individuals listed on Schedule II hereto and each officer and
director of the Company addressed to the Representatives.

                  (k) At the Closing Date, the Reorganization Transactions and
the Related Transactions shall have been consummated; and the Company shall have
provided to you or your counsel copies of all closing documents delivered to the
parties to the Reorganization Transactions and the Related Transactions.

                  If any of the conditions specified in this Section 6 shall not
have been fulfilled in all material respects when and as provided in this
Agreement, or if any of the opinions and certificates mentioned above or
elsewhere in this Agreement shall not be in all material respects reasonably
satisfactory in form and substance to the Representatives and counsel for the
Underwriters, this Agreement and all obligations of the Underwriters hereunder
may be canceled at, or at any time prior to, the Closing Date by the
Representatives. Notice of such cancelation shall be given to the Company in
writing or by telephone or facsimile confirmed in writing.

                  The documents required to be delivered by this Section 6 shall
be delivered at the office of Cleary, Gottlieb Steen & Hamilton, counsel for the
Underwriters, at 1 Liberty Plaza, New York City, NY 10006 on the Closing Date.

                  7. REIMBURSEMENT OF UNDERWRITERS' EXPENSES. If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 hereof is not satisfied,
because of any termination pursuant to Section 10 hereof or because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein or comply with any provision hereof other than by reason of a
default by any of the Underwriters, the Company will reimburse the Underwriters
severally through Salomon Smith Barney on demand for all out-of-pocket expenses
(including reasonable fees and disbursements of counsel) that shall have been
incurred by them in connection with the proposed purchase and sale of the
Securities.

                  8. INDEMNIFICATION AND CONTRIBUTION. (a) The Company agrees to
indemnify and hold harmless each Underwriter, the directors, officers, employees
and agents of each Underwriter and each person who controls any Underwriter
within the meaning of either the Act or the Exchange Act against any and all
losses, claims, damages or liabilities, joint or several, to


                                       23
<PAGE>

which they or any of them may become subject under the Act, the Exchange Act or
other Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in the registration statement for the
registration of the Securities as originally filed or in any amendment thereof,
or in any Preliminary Prospectus or the Prospectus, or in any amendment thereof
or supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and agrees to reimburse
each such indemnified party, as incurred, for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made
therein in reliance upon and in conformity with written information furnished to
the Company by or on behalf of any Underwriter through the Representatives
specifically for inclusion therein. This indemnity agreement will be in addition
to any liability which the Company may otherwise have.

                  (b) Each Underwriter severally and not jointly agrees to
indemnify and hold harmless the Company, each of its directors, each of its
officers who signs the Registration Statement, and each person who controls the
Company within the meaning of either the Act or the Exchange Act, to the same
extent as the foregoing indemnity from the Company to each Underwriter, but only
with reference to written information relating to such Underwriter furnished to
the Company by or on behalf of such Underwriter through the Representatives
specifically for inclusion in the documents referred to in the foregoing
indemnity. This indemnity agreement will be in addition to any liability which
any Underwriter may otherwise have. The Company acknowledges that the statements
set forth in any Preliminary Prospectus and the Prospectus constitute the only
information furnished in writing by or on behalf of the several Underwriters for
inclusion in any Preliminary Prospectus or the Prospectus.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure results
in the forfeiture by the indemnifying party of substantial rights and defenses
and (ii) will not, in any event, relieve the indemnifying party from any
obligations to any indemnified party other than the indemnification obligation
provided in paragraph (a) or (b) above. The indemnifying party shall be entitled
to appoint counsel of the indemnifying party's choice at the indemnifying
party's expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
PROVIDED, HOWEVER, that such counsel shall be satisfactory to the indemnified
party. Notwithstanding the indemnifying party's election to appoint counsel to
represent the indemnified party in an action, the indemnified party shall have
the right to employ separate counsel (including local counsel), and the
indemnifying party shall bear the reasonable fees, costs and expenses of such
separate counsel if (i) the use of counsel chosen by the indemnifying party to
represent the indemnified party would present such


                                       24
<PAGE>

counsel with a conflict of interest, (ii) the actual or potential defendants in,
or targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, (iii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. An indemnifying party will
not, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding.

                  (d) In the event that the indemnity provided in paragraph (a)
or (b) of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Underwriters severally
agree to contribute to the aggregate losses, claims, damages and liabilities
(including legal or other expenses reasonably incurred in connection with
investigating or defending same) (collectively "LOSSES") to which the Company
and one or more of the Underwriters may be subject in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and by the Underwriters on the other from the offering of the Securities;
PROVIDED, HOWEVER, that in no case shall any Underwriter (except as may be
provided in any agreement among underwriters relating to the offering of the
Securities) be responsible for any amount in excess of the underwriting discount
or commission applicable to the Securities purchased by such Underwriter
hereunder. If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the Company and the Underwriters severally shall
contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
of the Underwriters on the other in connection with the statements or omissions
which resulted in such Losses as well as any other relevant equitable
considerations. Benefits received by the Company shall be deemed to be equal to
the total net proceeds from the offering (before deducting expenses) received by
it, and benefits received by the Underwriters shall be deemed to be equal to the
total underwriting discounts and commissions, in each case as set forth on the
cover page of the Prospectus. Relative fault shall be determined by reference
to, among other things, whether any untrue or any alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information provided by the Company on the one hand or the
Underwriters on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The Company and the Underwriters agree that it
would not be just and equitable if contribution were determined by pro rata
allocation or any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of
this Section 8, each person who controls an Underwriter within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of an Underwriter shall have the same rights to contribution as such


                                       25
<PAGE>

Underwriter, and each person who controls the Company within the meaning of
either the Act or the Exchange Act, each officer of the Company who shall have
signed the Registration Statement and each director of the Company shall have
the same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).

                  9. DEFAULT BY AN UNDERWRITER. If any one or more Underwriters
shall fail to purchase and pay for any of the Securities agreed to be purchased
by such Underwriter or Underwriters hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Underwriters shall be obligated severally to take up
and pay for (in the respective proportions which the amount of Securities set
forth opposite their names in Schedule I hereto bears to the aggregate amount of
Securities set forth opposite the names of all the remaining Underwriters) the
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase; PROVIDED, HOWEVER, that in the event that the aggregate amount of
Securities which the defaulting Underwriter or Underwriters agreed but failed to
purchase shall exceed 10% of the aggregate amount of Securities set forth in
Schedule I hereto, the remaining Underwriters shall have the right to purchase
all, but shall not be under any obligation to purchase any, of the Securities,
and if such nondefaulting Underwriters do not purchase all the Securities, this
Agreement will terminate without liability to any nondefaulting Underwriter or
the Company. In the event of a default by any Underwriter as set forth in this
Section 9, the Closing Date shall be postponed for such period, not exceeding
five Business Days, as the Representatives shall determine in order that the
required changes in the Registration Statement and the Prospectus or in any
other documents or arrangements may be effected. Nothing contained in this
Agreement shall relieve any defaulting Underwriter of its liability, if any, to
the Company and any nondefaulting Underwriter for damages occasioned by its
default hereunder.

                  10. TERMINATION. This Agreement shall be subject to
termination in the absolute discretion of the Representatives, by notice given
to the Company prior to delivery of and payment for the Securities, if at any
time prior to such time (i) trading in the Company's Common Stock shall have
been suspended by the Commission or trading in securities generally on the New
York Stock Exchange shall have been suspended or limited or minimum prices shall
have been established on such Exchange, (ii) a banking moratorium shall have
been declared either by Federal or New York State authorities or (iii) there
shall have occurred any outbreak or escalation of hostilities, declaration by
the United States of a national emergency or war, or other calamity or crisis
the effect of which on financial markets is such as to make it, in the sole
judgment of the Representatives, impractical or inadvisable to proceed with the
offering or delivery of the Securities as contemplated by the Prospectus
(exclusive of any supplement thereto).

                  11. REPRESENTATIONS AND INDEMNITIES TO SURVIVE. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors, employees, agents or controlling persons referred to in
Section 8 hereof, and will survive delivery of and payment for the Securities.
The provisions of Sections 7 and 8 hereof shall survive the termination or
cancelation of this Agreement.

                                  INTRODUCTION

GENERAL

         This is the Plan of Incorporation, dated as of June 10, 1999 (this
"PLAN"), of LaBranche & Co., a New York limited partnership ("LABRANCHE LP"), to
facilitate, among other matters, an initial public offering (the "IPO") of the
common stock ("COMMON STOCK") of LaBranche & Co Inc., a Delaware corporation
(the "COMPANY"), which will own, directly or indirectly, substantially all of
the equity interest in LaBranche LP upon consummation of this Plan. The Managing
Committee (the "MANAGING COMMITTEE") of LaB Investing Co. L.L.C., a New York
limited liability company and the General Partner of LaBranche LP ("INVESTING"
or the "GENERAL PARTNER"), has unanimously approved this Plan and its submission
to the limited partners of LaBranche LP (collectively, the "LIMITED PARTNERS")
for their approval in accordance with the Amended and Restated Articles of
Partnership of LaBranche LP, dated as of January 1, 1998, as amended (the
"LABRANCHE PARTNERSHIP AGREEMENT"). If approved by the Limited Partners, this
Plan shall constitute (a) an agreement among LaBranche LP, Investing, the
Company and each of the Participating Limited Partners (as defined below) to
implement this Plan and all the transactions and agreements related hereto and
described herein and (b) effective upon consummation of the IPO, an amendment of
those provisions of the LaBranche Partnership Agreement which are inconsistent
with the provisions hereof.

CHOICES AVAILABLE TO LIMITED PARTNERS

         In connection with this Plan, each Limited Partner (other than Mill
Bridge, Inc. ("MILL BRIDGE") and Ernst & Company ("ERNST")) has been provided
with a Limited Partner Election Form ("LIMITED PARTNER ELECTION FORM") pursuant
to which such Limited Partner may elect to receive one of six optional packages
of consideration (the package of consideration selected by such Limited Partner
being referred to herein as the "EXCHANGE CONSIDERATION") in exchange for his,
her or its entire interest in LaBranche LP pursuant to this Plan. By selecting
one of the six optional packages of Exchange Consideration, a Limited Partner
will thereby consent to and approve the terms and conditions of this Plan,
including the provisions constituting an amendment of the LaBranche Partnership
Agreement, and will become bound by all other aspects of this Plan that may be
applicable to such Limited Partner (a "PARTICIPATING LIMITED PARTNER"). The
current assumed value of the Exchange Consideration which is allocable to each
such Limited Partner under this Plan is set forth on SCHEDULE A hereto.

         Under the LaBranche Partnership Agreement, Limited Partners who
formerly were members of Fowler, Rosenau & Geary, LLC (including, in particular,
Hilary Geary Trust, John R. Redmond, Louis V. Henston, Robert N. Westerlund, The
Jane Rosenau Trust A, The Jane Rosenau Trust B and James J. Boyle)
(collectively, the "FRG MEMBERS") may not be required to withdraw from LaBranche
LP for specified periods of time generally ranging from December 31, 2004
through November 30, 2007. Any FRG Member who presently cannot be required to
withdraw as a Limited Partner of LaBranche LP may retain his, her or its current
percentage interest in the profits of LaBranche LP by so indicating on the
Limited Partner Election Form, and by executing and

<PAGE>

delivering the Limited Partner Election Form to LaBranche LP. LaBranche LP,
subject to the approval of the New York Stock Exchange, may, at its discretion,
return to any such FRG Member the amount then credited to such FRG Member's
capital account.

         Investing and Mill Bridge have entered into an agreement (the "MILL
BRIDGE PURCHASE AGREEMENT"), pursuant to which, among other things, Investing
has agreed to acquire the entire interest of Mill Bridge in LaBranche LP for an
aggregate amount of $90 million upon consummation of the IPO. Of the amount to
be paid to Mill Bridge, $74 million will be paid in cash upon consummation of
the IPO and the remaining $16 million will be paid over three years in
accordance with the Mill Bridge Purchase Agreement. In addition, LaBranche LP
and Ernst have entered into an agreement (the "ERNST PURCHASE AGREEMENT"),
pursuant to which, among other things, LaBranche LP has agreed to redeem the
entire interest of Ernst in LaBranche LP for an aggregate amount of $28,176,000
to be paid in cash upon consummation of the IPO. In connection with these
agreements, Mill Bridge and Ernst have each agreed to waive their respective
rights to consent to this Plan under the LaBranche Partnership Agreement. The
Company intends to obtain substantially all of the amounts payable to Mill
Bridge and Ernst through a concurrent debt offering.

ACTION REQUIRED BY LIMITED PARTNERS

         Each Participating Limited Partner must complete the Limited Partner
Election Form and the Power of Attorney (the "POWER OF ATTORNEY") provided to
such Participating Limited Partner. See Section 11 hereof for a description of
the Power of Attorney that Participating Limited Partners must provide. Each FRG
Member who intends to retain his, her or its current percentage interest in the
profits of LaBranche LP should notify LaBranche LP of his, her or its intention
by so indicating on the Limited Partner Election Form. If LaBranche LP does not
receive a completed and executed Limited Partner Election Form and Power of
Attorney from an FRG Member by 5:00 p.m. on June 14, 1999, such FRG Member will
be deemed to have elected to retain his, her or its current percentage interest
in the profits of LaBranche LP. With respect to any other Limited Partner, if
LaBranche LP does not receive a completed and executed Limited Partner Election
Form and Power of Attorney from such Limited Partner by 5:00 p.m. on June 14,
1999, such Limited Partner will be deemed to have elected Option 6 on the
Limited Partner Election Form. Each Participating Limited Partner will become a
party to this Plan.

         1. GENERAL DESCRIPTION OF PROPOSED TRANSACTIONS

         The incorporation of LaBranche LP will be accomplished by (1) the
transfer by each member of Investing (the "EXCHANGING MEMBERS") of his or her
entire membership interest in Investing to the Company in exchange for shares of
Common Stock and (2) the transfer by each Participating Limited Partner of his,
her or its entire partnership interest in LaBranche LP to the Company in
exchange for Exchange Consideration consisting of (i) Common Stock, (ii)
subordinated debt of the Company ("SUBORDINATED DEBT"), (iii) cash or (iv) a
combination of the foregoing, as provided in such Participating Limited
Partner's completed and executed Limited Partner Election Form. The transactions
described in the preceding sentence are referred to herein to as the
"INCORPORATION TRANSACTIONS." Simultaneously with or immediately following the


                                       -2-
<PAGE>

Incorporation Transactions, the Company will consummate the IPO and the new debt
financing and transfer funds to Investing and LaBranche LP in order for those
entities to make payment to Mill Bridge and Ernst pursuant to the Mill Bridge
Purchase Agreement and the Ernst Purchase Agreement, respectively. The
transactions described in this paragraph are referred to herein collectively as
the "PROPOSED TRANSACTIONS." The LaBranche Partnership Agreement will be deemed
to have been amended effective upon consummation of the IPO. As described in
Section 7 hereof , the General Partner will have the right under this Plan,
subject to certain limitations, to vary the Proposed Transactions if it deems
any such changes to be reasonably necessary or desirable in order to effectuate
the purposes of this Plan.

         The Company is a Delaware corporation organized to be the direct or
indirect owner of 100% of the equity interest in LaBranche LP. The Company has
not conducted any business operations prior to the date of this Plan.

         A current draft of the Company's Registration Statement on Form S-1 for
the IPO is attached hereto as EXHIBIT A.

         2. DESCRIPTION OF EXCHANGE CONSIDERATION

         Each Participating Limited Partner will receive, in exchange for his,
her or its entire partnership interest in LaBranche LP, Common Stock,
Subordinated Debt, cash or a combination of the foregoing, as specified by each
Participating Limited Partner in his, her or its Limited Partner Election Form,
provided that a Participating Limited Partner may elect to receive Subordinated
Debt in a principal amount up to (but not exceeding) the amount of such Limited
Partner's capital account with LaBranche LP immediately prior to the
Incorporation Transactions, as determined in accordance with the LaBranche
Partnership Agreement. The Company will only issue whole shares of Common Stock
to a Participating Limited Partner. As a result, if a Participating Limited
Partner elects to receive Common Stock in respect of his, her or its capital
account with LaBranche LP, such Participating Limited Partner will receive cash
in lieu of any fractional share interest in Common Stock.

         Any Subordinated Debt of the Company or of LaBranche LP (i) would be
issued pursuant to a Cash Subordinated Loan Agreement ("CSLA") substantially in
the form required by the New York Stock Exchange, Inc. ("NYSE") for inclusion in
LaBranche LP's net capital for regulatory purposes, (ii) would provide for
quarterly payments of interest at an annual rate expected to approximate 8% and
(iii) generally would mature one year from the date of issuance, subject to an
automatic rollover provision for additional one-year terms unless the CSLA
holder notifies LaBranche LP of his, her or its intention not to renew the term
of the CSLA at least seven months prior to its scheduled maturity date. Subject
to NYSE approval, consideration may be given to certain adjustments in the terms
and conditions of the CSLA in order to address the concerns of certain Limited
Partners relating to the tax treatment of the Incorporation Transactions.

         A description of the Common Stock of the Company is contained in the
Registration Statement attached hereto as EXHIBIT A.


                                       -3-
<PAGE>

         Each Exchanging Member will receive solely Common Stock in exchange for
his, her or its membership interest in Investing pursuant to an Exchange
Agreement of even date herewith. The Participating Limited Partners and the
Exchanging Members are referred to collectively as the "EXCHANGING PARTIES."

         None of the Company's securities received by a Participating Limited
Partner in the Incorporation Transactions will be sold in the IPO. In addition,
the shares of Common Stock received by a Participating Limited Partner in
connection with the Incorporation Transactions will be subject to certain
"lock-up" restrictions which will prohibit the transfer of 50% of such shares of
Common Stock for a period of one year after the IPO and the transfer of the
remaining 50% of such shares of Common Stock for a period of two years after the
IPO. Common Stock received by Exchanging Members in the Incorporation
Transactions also will not be sold in the IPO and will be subject to certain
transfer restrictions. Exchanging Parties electing to receive Common Stock will
be deemed to have consented and agreed to the foregoing transfer restrictions,
as applicable. See Section 5 for a more complete description of the lock-up and
transfer restrictions provisions applicable to Participating Limited Partners
and Exchanging Members.

         The General Partner generally has the right, subject to certain
limitations, to amend this Plan in any respect that it deems reasonably
necessary or desirable in order to effectuate the purposes of this Plan. See
Section 7 for a discussion of those changes to this Plan that may give a
Participating Limited Partner who or which has previously elected to participate
in this Plan the right to withdraw its consent to this Plan or choose a
different package of Exchange Consideration.

                                    * * * * *

         The General Partner has the authority under this Plan not to offer
securities of the Company to or exchange securities of the Company with any
person or other entity if the General Partner determines, in its sole
discretion, that the making of such offer or the consummation of such exchange
could violate any applicable laws or regulations, including securities laws.

         3. EQUITY INCENTIVES AND COMPENSATION ARRANGEMENTS

         Prior to the date of the closing of the IPO (the "IPO DATE"), the
Company will adopt an equity incentive plan (the "EQUITY INCENTIVE PLAN")
pursuant to which options, restricted stock, restricted stock units and other
equity-based awards may be granted on a discretionary basis to employees and
consultants of the Company and LaBranche LP. Prior to the IPO Date, the Company
expects to grant stock options pursuant to the Equity Incentive Plan to the
Exchanging Members who are employed by LaBranche LP (including as consultants)
immediately following the IPO and to specialists in the employ of LaBranche LP
who are not Exchanging Members (collectively, the "EMPLOYEE STOCKHOLDERS"). The
options will have an exercise price per share equal to the IPO price. The
Company also expects to grant restricted stock units in connection with the IPO
to certain other employees. The options and restricted stock units will be
subject to certain vesting requirements.


                                       -4-
<PAGE>

         Prior to the IPO Date, the Company will adopt an annual incentive plan
(the "ANNUAL INCENTIVE PLAN") pursuant to which certain employees of LaBranche
LP, primarily the Employee Stockholders, will participate in an annual bonus
pool established by the Company provided that certain designated performance
goals are attained.

         By executing and delivering the Limited Partner Election Form and Power
of Attorney, each Participating Limited Partner thereby consents to and approves
the terms and conditions of the Equity Incentive Plan and the Annual Incentive
Plan.

         4. EMPLOYMENT AND NONCOMPETITION AGREEMENTS

         Each Exchanging Member who becomes an employee of the Company and/or
LaBranche LP will enter into an employment agreement with the Company and/or
LaBranche LP. The employment agreement will provide that such Exchanging Member
will have such duties and responsibilities as the Company and/or LaBranche LP
may from time to time determine and will devote his or her entire working time,
skill and energies to the business and affairs of the Company and/or LaBranche
LP. The employment agreements will require arbitration of disputes and will be
terminable by either party at any time upon 90 days' advance notice or by the
Company and/or LaBranche LP immediately upon the termination of the employment
of such Exchanging Member for "cause" or due to "disability" (as such terms are
defined in the employment agreements).

         The Company expects that each Exchanging Member will also enter into an
Agreement Regarding Noncompetition and Other Covenants (collectively, the
"NONCOMPETITION AGREEMENTS") pursuant to which such Exchanging Member will be
subject to certain restrictive employment covenants, including those relating to
noncompetition and nonsolicitation. Each Noncompetition Agreement will provide
that, in the event of certain breaches of the restrictive covenants, the
Exchanging Member will be liable for liquidated damages. The liquidated damages
obligations will be secured by a pledge of the Exchanging Member's shares of
Common Stock pursuant to a separate pledge agreement. The liquidated damages and
pledge arrangements will not be the sole or exclusive remedies available to the
Company or LaBranche LP for breaches of the Noncompetition Agreements.

         5. CERTAIN TRANSFER RESTRICTIONS ON SHARES

         Exchanging Parties will be subject to the following significant
restrictions on the Transfer (as hereinafter defined) of the Company's
securities received by them pursuant to this Plan. The Exchanging Members and
Employee Stockholders also will be parties to the Stockholders' Agreement
described in Section 6 below, which will impose further restrictions on
Transfers of the shares of Common Stock owned by each of them. Exchanging
Parties electing to receive Common Stock will be deemed to have consented and
agreed to the following transfer restrictions, as applicable.

         For purposes of the restrictions described in this Plan (including the
Exhibits hereto), the term "TRANSFER" generally includes any direct or indirect
offer, offer to sell, sale, contract of sale


                                       -5-
<PAGE>

or grant of any option to purchase, gift, transfer, pledge or other disposition
of securities of the Company, including any disposition of the economic or other
risks of ownership through hedging transactions or derivatives involving the
Company's securities, including hedging transactions that would constitute a
"constructive sale" within the meaning of Section 1259 of the Code (as defined
below) of the Company's securities.

UNDERWRITERS' LOCK-UP AND FIRM-WIDE TRADING RESTRICTIONS

         All shares of Common Stock which an Exchanging Party receives pursuant
to this Plan will be subject to the underwriters' lock-up restrictions in
connection with the IPO and, in the case of Employee Stockholders, to any
trading restrictions applicable to Employee Stockholders.

GENERAL TRANSFER RESTRICTIONS

         Subject to applicable securities laws, any securities that an
Exchanging Party receives pursuant to this Plan (other than shares of Common
Stock so designated by the Company prior to the IPO Date to accommodate
particular situations such as those referred to under Section 10) may be
Transferred only as follows (the "GENERAL TRANSFER RESTRICTIONS"):

         (a)      Participating Limited Partners may Transfer:

                  -        50% of such shares at any time after the first
                           anniversary of the IPO Date.

                  -        all of such shares at any time after the second
                           anniversary of the IPO Date.

         (b)      Exchanging Members may Transfer:

                  -        33 1/3% of such shares at any time after the third
                           anniversary of the IPO Date.

                  -        an additional 33 1/3% of such shares at any time
                           after the fourth anniversary of the IPO Date.

                  -        all of such shares at any time after the fifth
                           anniversary of the IPO Date.

         The General Transfer Restrictions may be waived or terminated only by
action of the Board of Directors of the Company (the "BOARD"). The General
Transfer Restrictions as to an Exchanging Party will terminate upon the death of
such Exchanging Party, although the underwriters' lock-up restrictions in the
IPO will continue to apply. If the Stockholders' Agreement is terminated prior
to the expiration or termination of the General Transfer Restrictions, the
General Transfer Restrictions will continue to apply unless waived or terminated
by action of the Board.


                                       -6-
<PAGE>

CUSTODY ARRANGEMENTS

         All shares of Common Stock issued to an Exchanging Party must be held
in a brokerage, custody or similar account maintained at a firm approved by the
Board. The Company will be entitled to monitor all activity in each Exchanging
Party account and to enforce applicable transfer and hedging restrictions and
any General Transfer Restrictions applicable to Exchanging Parties as in effect
from time to time. Any Common Stock held in such an account may be held of
record by a custodian or nominee. The Company may require each Exchanging Party
to execute a customary account agreement with the custodian or other firm, in
such reasonable form as the Company and such Exchanging Party shall mutually
determine (which may include customary provisions relating to indemnification of
the custodian or other firm and an undertaking to arbitrate custody-related
disputes).

                           6. STOCKHOLDERS' AGREEMENT

         Each Exchanging Member and Employee Stockholder will be subject to the
provisions of a Stockholders' Agreement, which will require, among other things,
that all shares covered by the Stockholders' Agreement (the "RESTRICTED SHARES")
be:

         (i)      held in a custody account until released for Transfer in
                  accordance with the provisions of the Stockholders' Agreement
                  and this Plan;

         (ii)     subject to certain transfer restrictions, including those
                  described above under Section 5; and

         (iii)    voted in accordance with the determination by a majority of
                  the Voting Executives (as defined therein).

                           7. AMENDMENTS TO THIS PLAN

         If the General Partner determines in good faith that an amendment to
this Plan is necessary or advisable, the General Partner, in its sole
discretion, may amend this Plan in any respect prior to the consummation of this
Plan, including an amendment of any Exhibits to this Plan; provided that an
amendment shall not be binding upon a Participating Limited Partner if it would
(a) change this Plan to lengthen or otherwise change in a manner materially
adverse to such Participating Limited Partner the transfer restrictions
described herein, (b) change the relative share of aggregate Exchange
Consideration (I.E., Common Stock, Subordinated Debt or cash) to be


                                       -7-
<PAGE>

received by such Participating Limited Partner in a manner that is materially
adverse to such Participating Limited Partner, or (c) amend the LaBranche
Partnership Agreement in a manner that would require the further consent of such
Participating Limited Partner without either (A) obtaining the consent of such
Participating Limited Partner or (B) in the case of an FRG Member, offering such
FRG Member the opportunity to withdraw his, her or its consent to this Plan;
provided, further, that the General Partner shall give each FRG Member prior
notice of any such amendment.

         Following consummation of this Plan, the Board may waive or amend any
aspect of this Plan that has not yet been completed or reflected in a separate
agreement.

                               8. TAX CONSEQUENCES

TREATMENT OF EXCHANGING PARTIES

         The transfer of membership and partnership interests in Investing and
LaBranche LP by the Exchanging Parties to the Company for Common Stock,
Subordinated Debt and/or cash should qualify as contributions to a controlled
corporation under Section 351 of the United States Internal Revenue Code of
1986, as amended (the "CODE"). As a result, the following U.S. federal income
tax consequences generally will apply to an Exchanging Party:

         PARTICIPATING LIMITED PARTNERS WHO DO NOT ELECT TO RECEIVE SUBORDINATED
DEBT. Except as discussed in the next sentence, no gain or loss will be
recognized by a Participating Limited Partner who exchanges his, her or its
interest in LaBranche LP solely for Common Stock, except to the extent cash is
received in lieu of a fractional share interest in Common Stock. If a
Participating Limited Partner elects to receive cash in exchange for all or a
portion of such Participating Limited Partner's interest in LaBranche LP, or
receives cash in lieu of a fractional share interest in Common Stock, such
Participating Limited Partner generally will recognize gain to the extent of the
lesser of the aggregate amount of cash received or the gain realized on the
exchange (that is, the fair market value of the cash and Common Stock received
less the Participating Limited Partner's adjusted tax basis in his, her or its
interest in LaBranche LP). Such a Participating Limited Partner's adjusted tax
basis in the Common Stock generally will be equal to the Participating Limited
Partner's adjusted tax basis in the interest transferred (calculated without
regard to the Participating Limited Partner's direct or indirect share of any
liabilities of LaBranche LP), reduced by the amount of any cash received in the
exchange and increased by any gain recognized in the exchange.

         PARTICIPATING LIMITED PARTNERS WHO ELECT TO RECEIVE SUBORDINATED DEBT.
Subordinated Debt received by a Participating Limited Partner may qualify for
installment sale treatment under Section 453 of the Code. If a Participating
Limited Partner elects to receive Common Stock, Subordinated Debt and cash, and
does not elect out of installment sale treatment, his, her or its adjusted tax
basis in the partnership interest relinquished (calculated without regard to the
Participating Limited Partner's (direct or indirect) share of any liabilities of
LaBranche LP) will be reduced by the amount of any cash received in the exchange
and increased by any gain recognized in the exchange. Such adjusted tax basis
will be allocated to the Common Stock received in an amount up to (but not
exceeding) the fair market value of such Common Stock.


                                       -8-
<PAGE>

         If the exchange is viewed as separate transfers by such Participating
Limited Partner of his, her or its interest in the "hot assets" (I.E.,
inventory) of LaBranche LP (on the one hand) and the other assets of LaBranche
LP (on the other), the receipt of cash in the exchange and/or the receipt of
payments on, or proceeds from, the sale of Subordinated Debt, to the extent
attributable to such hot assets, generally would not result in gain recognition,
and a Participating Limited Partner's adjusted tax basis in such Common Stock
received would be adjusted accordingly.

         PARTICIPATING LIMITED PARTNERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS REGARDING THE FEDERAL (AS WELL AS STATE AND LOCAL) INCOME TAX
CONSEQUENCES TO THEM OF THEIR PARTICULAR PACKAGE OF EXCHANGE CONSIDERATION.

         EXCHANGING MEMBERS. No gain or loss will be recognized by an Exchanging
Member who receives Common Stock of the Company in exchange for his or her
membership interest in Investing. The Exchanging Member's tax basis in the
Common Stock will be equal to his or her adjusted tax basis in the membership
interest transferred (calculated without regard to the Exchanging Member's
direct or indirect share of any liabilities of Investing).

                          9. MANAGEMENT OF THE COMPANY

         The Amended and Restated Certificate of Incorporation of the Company
will provide for a classified Board consisting of three classes. It is
anticipated that at the IPO Date a majority of the Board will be drawn from the
current members of the Managing Committee. Beginning in 2000, at each annual
meeting of the stockholders, directors will be elected for three-year terms and
shall hold office until their respective successors have been elected and
qualified. A director may be removed only for cause and only by the affirmative
vote of the holders of not less than 75% of the outstanding shares of capital
stock entitled to vote in the election of directors.

         The Company will enter into an indemnification agreement with each
director of the Company and each officer of the Company who signs the
registration statement for the IPO and the other registration statements to be
filed by the Company, to indemnify them for actions taken in consummating the
transactions contemplated by this Plan.

                                    10. OTHER

ARBITRATION

         Without diminishing the finality and conclusive effect of any
determination by the Managing Committee or by the Board of any matter under this
Plan which is provided herein to be determined by the Managing Committee or by
the Board, any dispute, controversy or claim arising out of or relating to or
concerning the provisions of this Plan or any Exhibits to this Plan shall be
finally settled by arbitration in New York City before, and in accordance with
the rules then obtaining of, the NYSE or, if the NYSE declines to arbitrate the
matter, the American Arbitration Association ("AAA") in accordance with the
commercial arbitration rules of the AAA; provided however, that, in addition to
the right to compel arbitration of any dispute or controversy, the


                                       -9-
<PAGE>

Company, Investing or LaBranche LP may bring an action or special proceeding in
a state or federal court of competent jurisdiction sitting in New York City,
whether or not an arbitration proceeding has theretofore been or is ever
initiated, for the purpose of temporarily, preliminarily, or permanently
enforcing the provisions of this Plan or to enforce an arbitration award. For
the purposes of this provision, each participant in this Plan expressly consents
to the jurisdiction of any such court in respect of any such action and waives
to the fullest extent permitted by applicable law any objection to personal
jurisdiction or to the laying of venue of any such suit, action or proceeding in
such court, agrees that proof shall not be required to establish that monetary
damages for breach of the provisions of this Plan would be difficult to
calculate and that remedies at law would be inadequate for any such breach and
irrevocably appoints George M.L. LaBranche, IV as the participant's agent for
service of process in connection with any such action or proceeding, who shall
promptly notify such participant of the receipt of any such service of process.

DETERMINATIONS UNDER PLAN

         Each party to this Plan agrees that the Managing Committee and,
following the IPO Date, the Board shall have the right to make all
determinations under this Plan and each Exhibit to this Plan.

LABRANCHE PARTNERSHIP AGREEMENT

         If adopted, this Plan (including SCHEDULE A hereto) shall constitute,
effective upon consummation of the IPO, an amendment to the LaBranche
Partnership Agreement, and the provisions of this Plan, to the extent that they
are inconsistent with the LaBranche Partnership Agreement, will control. The
provisions of the LaBranche Partnership Agreement will continue to apply to all
partners until the IPO Date. FRG Members who do not elect one of the six
optional packages of Exchange Consideration described in the Limited Partner
Election Form will not be subject to any amendment to the LaBranche Limited
Partnership Agreement effected by this Plan to the extent that such FRG Member's
interest in LaBranche LP is affected by such amendment. For all purposes hereof,
a deceased Limited Partner of LaBranche LP (or the estate of a deceased Limited
Partner of LaBranche LP) will continue to be treated as a Limited Partner of
LaBranche LP under this Plan.

ABANDONMENT AND TERMINATION OF PLAN

         This Plan may be abandoned at any time prior to the IPO by the Managing
Committee. If the IPO has not been consummated by December 31, 1999, unless
re-approved, this Plan will be automatically abandoned and will be of no further
force and effect.

RELEASE

         Each Participating Limited Partner will, by virtue of such
participation, irrevocably release the Company, Investing, LaBranche LP, each
and every affiliate, stockholder, subsidiary, partner, officer, member, director
and employee of the Company, Investing and LaBranche LP in


                                      -10-
<PAGE>

their capacities as such and each other participant in this Plan ("RELEASEES")
from any claims, liabilities, costs, expenses, actions, suits or demands however
arising, whether at law or in equity, contingent, known or unknown, which any
such participant may have or assert, in respect of any interest in LaBranche LP
or Investing or arising out of any partnership or employment relationship with
LaBranche LP or Investing that such participant or such participant's heirs,
successors or assigns had with any such Releasee on or prior to the IPO Date;
provided that this release shall not extend to (i) indebtedness owing to a
participant in this Plan by any Releasee, (ii) representations or warranties
made or agreements entered into by a Releasee in connection with this Plan, and
(iii) any conduct that resulted from Releasee's bad faith, fraud or criminal act
or omission.

REPRESENTATIONS AND WARRANTIES

         Each Participating Limited Partner will, by executing and delivering a
Limited Partner Election Form and Power of Attorney, be deemed to make the
representations and warranties set forth on EXHIBIT B attached hereto.

RIGHT OF GENERAL PARTNER OR THE COMPANY
TO MAKE SPECIAL ARRANGEMENTS

         The transactions included in this Plan have been structured in a manner
that is expected not to result in a significantly disproportionate tax or other
burden to any Exchanging Party in any jurisdiction. If it develops that the
consummation of this Plan would, in fact, have (or had) such an impact, the
Managing Committee and the Board will have the right, but not the obligation, at
any time either before or after the IPO Date to make special arrangements with
any Exchanging Party or such Exchanging Party's estate or legal representative
(including special payments) to ameliorate, in whole or in part, such adverse
impact. Each party to this Plan recognizes, acknowledges and agrees that this
paragraph shall not create any right on the part of such party to any such
special arrangement or accommodation.

         Each party to this Plan hereby waives, and each future stockholder of
the Company will be deemed to have waived, any right to object to a decision by
the Managing Committee or the Board to make such special arrangements.

BENEFIT

         Nothing in this Plan, express or implied, is intended or shall be
construed to confer upon or give to any person or other entity other than
LaBranche LP, Investing, the Company and, to the extent expressly provided
herein, the Exchanging Parties and any other person participating in this Plan
any remedy or claim under or by reason of this Plan or any term, covenant or
condition hereof, all of which shall be for the sole and exclusive benefit of
the parties mentioned above in this paragraph; except that the provision set
forth above in this Section 10 under "Release" shall be enforceable by the
Releasees mentioned therein.

M.L. LaBranche, IV, as agent or attorney-in-fact for the participants in this
Plan, any notices, demands, requests and other communications required or

inducements in connection with this Plan other than as provided herein.

                               EXCHANGE AGREEMENT


         This EXCHANGE AGREEMENT (this "AGREEMENT") is dated as of June ___,
1999, by and among (i) LaBranche & Co Inc., a Delaware corporation (the
"COMPANY"), (ii) LaB Investing Co. L.L.C., a New York limited liability company
("INVESTING"), and (iii) the members of Investing listed on SCHEDULE A hereto
(collectively, the "EXCHANGING MEMBERS" and, each, an "EXCHANGING MEMBER").

                              W I T N E S S E T H :

         WHEREAS, the Company is contemplating an initial public offering (the
"IPO") of its common stock, $.01 par value per share ("COMMON STOCK");

                                   ARTICLE II

                         REPRESENTATIONS AND WARRANTIES

         As of the date hereof and as of the Effective Time, each Exchanging
Member severally represents and warrants to the Company as follows:

         Section 2.1. ENFORCEABILITY. Such Exchanging Member is of sound mind
and has full legal capacity to enter into, execute and deliver this Agreement
and the other documents contemplated hereby and perform his or her obligations
hereunder and thereunder, and each of this Agreement and the other documents
contemplated hereby has been duly executed and delivered by such Exchanging
Member and constitutes a legal, valid and binding obligation of such Exchanging
Member, enforceable against such Exchanging Member in accordance with its terms,
except as such enforceability may be limited by any applicable bankruptcy,
insolvency, moratorium or other laws relating to or affecting creditors' rights
generally and the exercise of judicial discretion in accordance with general
equitable principles.

         Section 2.2. TITLE. Such Exchanging Member owns, beneficially and of
record, his or her Membership Interest, free and clear of any claim, lien,
pledge, deed of trust, option, charge, security interest, hypothecation,
encumbrance, right of first offer, voting trust, proxy, right of third parties
or other restriction or limitation of any nature whatsoever (collectively,
"LIENS" and each, a "LIEN"). At the Effective Time, the Company will acquire
good and valid title to such Membership Interest, free and clear of any Liens
other than any Lien created by the Company.

         Section 2.3. NO CONFLICTS. Subject to compliance with the rules and
regulations of the New York Stock Exchange (the "NYSE") and federal and state
securities laws, the execution, delivery and performance of this Agreement and
the other documents contemplated hereby, and the consummation of the
transactions contemplated hereby and thereby, will not conflict with,
contravene, result in a violation or breach of or default under (with or without
the giving of notice or the lapse of time or both), permit any party to
terminate, amend or accelerate the provisions of, or result in the imposition of
any Lien (or any obligation to create any Lien) upon any of the property or
assets of such Exchanging Member under any contract, agreement, indenture,
letter of credit, mortgage, security agreement, pledge agreement, deed of trust,
bond, note, guarantee, surety obligation, warranty, license, franchise, permit,
power of attorney, lease, instrument or other agreement to which such Exchanging
Member is a party or by which any of his or her property or assets may be bound.

         Section 2.4. ACCREDITED INVESTOR. Such Exchanging Member is an
"accredited investor," as defined in Rule 501(a) of Regulation D under the
Securities Act of 1933, as amended (the "SECURITIES ACT").


                                                       3
<PAGE>

         Section 2.5. INVESTMENT PURPOSE. Such Exchanging Member is acquiring
shares of Common Stock under this Agreement for his or her own account for
investment purposes, and not with a view to, or for resale in connection with,
any distribution thereof other than in compliance with the Securities Act and
other applicable securities laws. Such Exchanging Member acknowledges that he or
she must bear the economic risk of an investment in the Common Stock for an
indefinite period of time because, among other reasons, the shares of Common
Stock received by such Exchanging Member have not been registered under the
Securities Act and, therefore, such securities cannot be sold unless
subsequently registered under the Securities Act or an exemption from such
registration is available. Such Exchanging Member also acknowledges that
transfers of the shares of Common Stock received are further restricted by
applicable United States federal and state and foreign securities laws.

         Section 2.6. ACCESS TO INFORMATION. Such Exchanging Member understands
the risks of, and other considerations relating to his or her acquisition and
ownership of the shares of Common Stock received. Such Exchanging Member has
been provided an opportunity to ask questions of, and has received answers
satisfactory to him or her from, the Company, LaBranche LP, Investing and their
representatives regarding the shares of Common Stock received, and has obtained
any and all additional information from the Company and its representatives that
such Exchanging Member deems necessary regarding the shares of Common Stock
received.

         Section 2.7. EVALUATION OF AND ABILITY TO BEAR RISKS. Such Exchanging
Member has such knowledge and experience in financial affairs that he or she is
capable of evaluating the merits and risks of, and other considerations relating
to, the ownership of the shares of Common Stock received, and has not relied in
connection with his or her acquisition of the shares of Common Stock received
upon any representations, warranties or agreements other than those set forth in
this Agreement. Such Exchanging Member's financial situation is such that he or
she can afford to bear the economic risk of holding the shares of Common Stock
for an indefinite period of time, and such Exchanging Member can afford to
suffer the complete loss of his or her investment in such securities.

         Section 2.8. NO DISPOSITIONS. Such Exchanging Member does not currently
have, and at the Effective Time will not have, any plan, agreement, commitment,
intention or arrangement, whether written or oral, to dispose of any of the
shares of Common Stock to be received by such Exchanging Member. For purposes of
this representation, a "disposition" shall include any direct or indirect offer,
offer to sell, sale, contract of sale or grant of any option to purchase, gift,
transfer, pledge or other disposition, including any disposition of the economic
or other risks of ownership through hedging transactions or derivatives and any
other transaction that would constitute a "constructive sale" within the meaning
of Section 1259 of the United States Internal Revenue Code of 1986, as amended
(the "CODE"), including, without limitation, a short-sale, forward sale, equity
swap or other derivative contract with respect to the Common Stock or
substantially identical property, or other transaction having substantially the
same effect as the foregoing.

shall mutually determine (which may include customary provisions relating to
indemnification of the custodian or other firm and an undertaking to arbitrate

received by such Exchanging Member in the LLC Exchange relative to the other
Exchanging Members (other than Steven C. Berger, Paul Redmond and Robert W.

<PAGE>

                  (b) The Managing Committee has the authority under this
Agreement not to offer securities of the Company to or exchange securities of

exchange, the Managing Committee may, pursuant to Section 10(b) of the Amended
and Restated Operating Agreement of Investing, dated as of January 1, 1998, as

with the prior written consent of the Company, and any assignment without such
consent by the Company shall be void.

         Section 5.6. BENEFIT. Nothing in this Agreement, express or implied, is
intended or shall be construed to confer upon or give to any person or other
entity (other than Investing or the Company and, to the extent expressly
provided herein, an Exchanging Member) any remedy or claim under or by reason of
this Agreement or any term, covenant or condition hereof, all of which shall be
for the sole and exclusive benefit of the parties mentioned above in this
Section, except that the provision set forth above in Section 3.10, entitled
"Release," shall be enforceable by the Releasees mentioned therein.

LAW PROVISIONS OF ANY EXHIBIT AS IT SHALL DEEM NECESSARY OR DESIRABLE PRIOR TO
THE EFFECTIVE TIME.

         Section 5.8. ARBITRATION. Without diminishing the finality and
conclusive effect of any determination by the Managing Committee of any matter
under this Agreement, which is provided herein to be determined by the Managing
Committee, any dispute, controversy or claim arising out of or relating to or
concerning the provisions of this Agreement or any of the Exhibits hereto shall
be finally settled by arbitration in New York City before, and in accordance
with the rules then obtaining of, the NYSE or, if the NYSE declines to arbitrate
the matter, the American Arbitration Association ("AAA") in accordance with the
commercial arbitration rules of the AAA; PROVIDED HOWEVER, that, in addition to
the right to compel arbitration of any dispute or controversy, the Company or
Investing may bring an action or special proceeding in a state or federal court
of competent jurisdiction sitting in New York City, whether or not an
arbitration proceeding has theretofore been or is ever initiated, for the
purpose of temporarily, preliminarily, or permanently enforcing the provisions
of this Agreement or to enforce an arbitration award and, for the purposes of
this provision, each Exchanging Member expressly consents to the jurisdiction of
any such court in respect of any such action and waives to the fullest extent
permitted by applicable law any objection to personal jurisdiction or to the
laying of venue of any such suit, action or proceeding in such court, agrees
that proof shall not be required that monetary damages for breach of the
provisions of this Agreement would be difficult to calculate and that remedies
at law would be inadequate and irrevocably appoints George M.L. LaBranche, IV as
such Exchanging Member's


                                        9
<PAGE>

agent for service of process in connection with any such action or proceeding,
who shall promptly advise such participant of any such service of process.

         Section 5.9. FURTHER ASSURANCES. Each Exchanging Member agrees to
execute such additional documents and take such further action as may be
requested by the Company to effect the provisions of this Agreement.

         Section 5.10. HEADINGS. The headings of the Sections of this Agreement
are inserted as a matter of convenience and for reference purposes only, are of
no binding effect, and in no respect define, limit or describe the scope of this
Agreement or the intent of any Section.

         Section 5.11. COUNTERPARTS. This Agreement may be executed in any
number of counterparts, each of which shall be deemed an original, but all such
counterparts shall together constitute but one and the same instrument.

nor the Company has made representations, warranties, promises or inducements in
connection with this Agreement other than as provided herein.

                              AMENDED AND RESTATED
                          CERTIFICATE OF INCORPORATION
                                       OF
                               LABRANCHE & CO INC.


      (Under Sections 242 and 245 of the Delaware General Corporation Law)

     It is hereby certified that:

     1.   The name of the Corporation is LaBranche & Co Inc. (the
          "Corporation").

     2.   The Certificate of Incorporation of the Corporation originally filed
          with the Secretary of State of the State of Delaware on June 15, 1999
          is hereby amended and restated in its entirety to read as follows:


     "FIRST: The name of the corporation is LaBRANCHE & CO INC. (the
"Corporation").

     SECOND: The address of the Corporation's registered office in the State of
Delaware is United Corporate Services, Inc., 15 East North Street, Dover, DE
19901. The name of the Corporation's registered agent at such address is United
Corporate Services.

     THIRD: The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of the State of Delaware (the "GCL").

     FOURTH: Section 1. CLASSES AND NUMBER OF SHARES. The total number of shares
of all classes of stock which the Corporation has authority to issue is two
hundred ten million (210,000,000) shares, consisting of two hundred million
(200,000,000) shares of Common Stock, par value $.01 per share (the "Common
Stock"), and ten million (10,000,000) shares of Preferred Stock, par value $.01
per share, which shall have such designations as may be authorized by the Board
of Directors from time to time (the "Preferred Stock").

     Section 2. PREFERRED STOCK. The Board of Directors is hereby authorized,
subject to the provisions contained in this Article Fourth, to issue the
Preferred Stock from time to time in one or more series, which Preferred Stock
shall rank senior to the Common Stock as to dividends and distribution of assets
of the Corporation on dissolution, as hereinafter provided, and shall have such

<PAGE>

distinctive designations as may be stated in the resolution or resolutions
providing for the issue of such stock adopted by the Board of Directors. In such
resolution or resolutions providing for the issuance of shares of a particular
series of Preferred Stock, the Board of Directors is hereby expressly authorized
and empowered to fix the number of shares constituting such series and to fix
the relative rights and preferences of the shares of the series so established
to the full extent allowable by law except insofar as such rights and
preferences are fixed herein. Such authorization of the Board of Directors shall
expressly include the authority to fix and determine the relative rights and
preferences of such shares in all respects including, without limitation, the
following:

          1.   the rate of dividend;

          2.   whether shares can be redeemed or called and, if so, the
               redemption or call price and terms and conditions of redemption
               or call;

          3.   the amount payable upon shares in the event of dissolution,
               voluntary and involuntary liquidation or winding up of the
               affairs of the Corporation;

          4.   purchase, retirement or sinking fund provisions, if any, for the
               call, redemption or purchase of shares;

          5.   the terms and conditions, if any, on which shares may be
               converted into Common Stock or any other securities;

          6.   whether or not shares have voting rights, and the extent of such
               voting rights, if any; and

          7.   whether shares shall be cumulative, noncumulative, or partially
               cumulative as to dividends and the date from which any cumulative
               dividends are to accumulate.

     FIFTH: Meetings of the stockholders of the Corporation may be held within
or without the State of Delaware, as the Bylaws may provide. The books of the
Corporation may be kept (subject to any provisions contained in the statutes)
outside the State of Delaware at such place or places as may be designated from
time to time by the Board of Directors or in the Bylaws of the Corporation.
Elections of directors need not be by written ballot unless the Bylaws of the
Corporation shall so provide.

     SIXTH: In the furtherance and not in limitation of objects, purposes and
powers conferred by statute, the Board of Directors is expressly authorized to
make, alter or repeal the Bylaws of the Corporation. Notwithstanding anything in
this Amended and Restated Certificate of Incorporation to the contrary, Bylaw
Sections 2.04, 3.02, 3.03, and Article XII may not be repealed or amended in any
respect, and no provision inconsistent therewith may be adopted by the


                                       -2-

<PAGE>

stockholders unless such action is approved by either (a) a majority of the
Continuing Directors ( in addition to the vote otherwise required by the GCL) or
(b) the affirmative vote of the holders of (i) eighty percent (80%) of the
outstanding Voting Shares voting as a single class and (ii) if an Interested
Stockholder, either directly or indirectly, through agreement or any other
arrangement, proposes such amendment, sixty-six and two-thirds percent (66 2/3%)
of the outstanding Voting Shares which are not beneficially owned, directly or
indirectly, by such Interested Stockholder, voting as a single class.

     SEVENTH: Subject to the rights of the holders of any series of Preferred
Stock:

     (a)  any action required or permitted to be taken by the stockholders of
          the Corporation must be effected at a duly called annual or special
          meeting of stockholders of the Corporation and may not be effected by
          any consent in writing of such stockholders and

     (b)  special meetings of stockholders of the Company may be called only by
          (i) the Chairman of the Board or (ii) the Secretary of the Corporation
          within 10 calendar days after receipt of the written request of a
          majority of the total number of Directors which the Corporation would
          have if there were no vacancies.

     At any annual or special meeting of stockholders of the Corporation, only
such business will be conducted or considered as has been brought before such
meeting in the manner provided in the By Laws of the Corporation.
Notwithstanding anything in this Amended and Restated Certificate of
Incorporation to the contrary, the provisions set forth in this Article Seventh
may not be repealed or amended in any respect, unless such action is approved by
either (a) a majority of the Continuing Directors (in addition to the vote
otherwise required by the GCL) or (b) the affirmative vote of the holders of (i)
eighty percent (80%) of the Voting Shares voting as a single class, and (ii) if
an Interested Stockholder, either directly or indirectly, through agreement or
any or arrangement, proposes such amendment, sixty-six and two-thirds percent
(66 2/3%) of the Voting Shares which are not beneficially owned, directly or
indirectly, by such Interested Stockholder, voting as a single class.

     EIGHTH: (a) CLASSIFICATION OF BOARD OF DIRECTORS. The Board of Directors
shall consist of five (5) directors; provided that the number of directors may
be increased from time to time by resolution adopted by the affirmative vote of
a majority of the Continuing Directors. Upon the consummation of the
Corporation's initial public offering of its Common Stock, directors shall be
divided into three classes, designated Class I, Class II and Class III. Each
class shall consist, as nearly as may be possible, of one-third of the total
number of directors constituting the entire Board of Directors. Class I
directors shall serve until the 2000 Annual Meeting of Stockholders, Class II
directors shall serve until the 2001 Annual Meeting of Stockholders and Class
III directors shall serve until the 2002 Annual Meeting of Stockholders. At each
annual meeting of stockholders beginning in 2000, successors to the class of
directors whose term expires at that annual meeting

                                       -3-


<PAGE>

shall be elected for a three-year term. If the number of directors is changed,
any increase or decrease shall be apportioned among the classes so as to
maintain the number of directors in each class as nearly equal as possible, and
any additional director of any class elected to fill a vacancy resulting from an
increase in such class shall hold office for a term that shall coincide with the
remaining term of the class, but in no case will a decrease in the number of
directors shorten the term of any incumbent director. A director shall hold
office until the annual meeting for the year in which his or her term expires
and until his or her successor shall be elected and qualified. Any vacancy on
the Board of Directors for any reason, and any directorships resulting from any
increase in the number of directors of the Board of Directors, may be filled by
a majority of the Board of Directors then in office, although less than a
quorum, or a sole remaining director and any directors so chosen shall hold
office until the next election of the class for which such directors shall have
been chosen and until their successors shall be elected and qualified.
Notwithstanding the foregoing, whenever the holders of any one or more classes
or series of stock issued by the Corporation shall have the right, voting
separately by class or series, to elect directors at an annual or special
meeting of stockholders, the election, term of office, filling of vacancies and
other features of such directorships shall be governed by the terms of this
Amended and Restated Certificate of Incorporation applicable thereto, such
directors so elected shall not be divided into classes pursuant to this Article
Eighth, Section(a), and the number of such directors shall not be counted in
determining the maximum number of directors permitted under the foregoing
provision of this Article Eighth, Section (a), in each case unless expressly
provided by such terms.

     (b) AMENDMENT OR REPEAL. Notwithstanding anything in this Amended and
Restated Certificate of Incorporation to the contrary, the provisions set forth
in this Article Eighth may not be repealed or amended in any respect, unless
such action is approved by either (a) a majority of the Continuing Directors (in
addition to the vote otherwise required by the GCL) or (b) the affirmative vote
of the holders of (i) eighty percent (80%) of the Voting Shares voting as a
single class, and (ii) if an Interested Stockholder, either directly or
indirectly, through agreement or any other arrangement, proposes such amendment,
sixty-six and two-thirds percent (66 2/3%) of the Voting Shares which are not
beneficially owned, directly or indirectly, by such Interested Stockholder,
voting as a single class.

     (c) REMOVAL OF DIRECTORS. Notwithstanding anything in this Amended and
Restated Certificate of Incorporation to the contrary, the Corporation's
Certificate of Incorporation may not be amended to provide for removal of
directors without cause as permitted by the GCL, unless such action is approved
by either (a) a majority of the Continuing Directors (in addition to the vote
otherwise required by the GCL) or (b) the affirmative vote of the holders of (i)
eighty percent (80%) of the Voting Shares voting as a single class, and (ii) if
an Interested Stockholder, either directly or indirectly, through agreement or
any other arrangement, proposes such amendment, sixty-six and two-thirds percent
(66 2/3%) of the Voting Shares which are not beneficially owned, directly or
indirectly, by such Interested Stockholder, voting as a single class; PROVIDED,
HOWEVER, whenever the holders of any class or series of the Corporation's
outstanding securities are entitled to elect one or more directors by this
Amended and Restated Certificate of Incorporation, this subsection shall

                                      -4-
<PAGE>

apply, in respect to the removal without cause of a director or directors
so elected, to the vote of the holders of the outstanding shares of that class
or series and not to the vote of the outstanding Voting Shares as a whole.

     (d) DEFINITIONS. A majority of the Continuing Directors shall have the
power and duty to determine for purposes of Article Sixth through Article
Eighth, on the basis of information known to them, the applicability of certain
defined terms used in Article Sixth through Article Eighth, in addition to such
other matters with respect to which a determination is required under Article
Sixth through Article Eighth. Any such determination shall be conclusive and
binding for all purposes of Article Sixth through Article Eighth.

     For purposes of Article Sixth through Article Eighth, the following
     definitions shall apply:

     "Affiliate" and "Associate" shall have the respective meanings ascribed to
     them in Rule 12b-2 of the General Rules and Regulations under the
     Securities Exchange Act of 1934, as amended (the "Exchange Act").

     A person shall be a "beneficial owner" of any Voting Shares:

          (i) which such person or any of its Affiliates or Associates
     beneficially owns, directly or indirectly; or

          (ii) which such person or any of its Affiliates or Associates has (1)
     the right to acquire (whether such right is exercisable immediately or only
     after the passage of time) pursuant to any agreement, arrangement or
     understanding or upon the exercise of conversion rights, exchange rights,
     warrants or options, or otherwise or (2) the right to vote or to direct the
     voting thereof pursuant to any agreement, arrangement or understanding; or

          (iii) which is beneficially owned, directly or indirectly, by any
     other person with which such person or any of its Affiliates or Associates
     has any agreement, arrangement or understanding for the purpose of
     acquiring, holding, voting or disposing of any Voting Shares.

     A "Continuing Director" is any member of the Corporation's Board of
     Directors who is unaffiliated with, and not a nominee of, an Interested
     Stockholder, and any successor of a Continuing Director who is unaffiliated
     with, and not a nominee of, an Interested Stockholder and is approved to
     succeed a Continuing Director by a majority of Continuing Directors then on
     the Board of Directors.

     "Interested Stockholder" shall mean any Person (other than (i) the
     Corporation, (ii) any Subsidiary (or any successor in interest to any
     Subsidiary) of the Corporation,

                                   -5-

<PAGE>

     (iii) any member of the group of stockholders (or any successor in interest
     to such group), including the Chief Executive Officer, who, pursuant to
     Article II of the Stockholders' Agreement, has a power to direct the vote
     of the stockholders who are or become parties thereto, (iv) any employee
     benefit plan of the Corporation or any Subsidiary of the Corporation or any
     entity holding shares of Common Stock for or pursuant to the terms of any
     such plan or (v) any person who acquires more than 10% of the outstanding
     Voting Shares with the prior approval of a majority of the Continuing
     Directors), who or which:

          (i) is the beneficial owner, directly or indirectly, of more than 10%
     of the combined voting power of the then outstanding Voting Shares; or

          (ii) is an assignee of or has otherwise succeeded to the beneficial
     ownership of any Voting Shares which were at any time within the three-year
     period immediately prior to the date in question beneficially owned by an
     Interested Stockholder.

     For the purposes of determining whether a person is an Interested
     Stockholder, the number of Voting Shares deemed to be outstanding shall
     include shares deemed owned through application of the definition of
     beneficial ownership provided above but shall not include any Voting Shares
     beneficially owned by any person other than the Interested Stockholder
     which may be issuable pursuant to any agreement, arrangement or
     understanding or upon exercise of conversion rights, warrants or options,
     or otherwise.

     "Person" shall mean any individual, firm, trust, partnership, association,
     corporation, unincorporated organization or other entity (other than the
     Corporation, any Subsidiary of the Corporation for itself or a trustee
     holding stock for the benefit of the employees of the Corporation or its
     Subsidiaries, or any one of them, pursuant to one or more employee benefit
     plans or arrangements), as well as two or more persons acting as a
     partnership, limited partnership, syndicate, association or other group for
     the purpose of acquiring, holding or disposing of shares of stock.

     "Subsidiary" shall mean any corporation, limited liability company,
     partnership or other entity of which a majority of any class of equity
     security (as defined in Rule 3a11-1 of the General Rules and Regulations
     under the Exchange Act), is owned, directly or indirectly, by the
     Corporation; provided, however, that for purposes of the definition of
     Interested Stockholder set forth above, the term "Subsidiary" shall mean
     only a corporation, limited liability company, partnership or other entity
     of which a majority of each class of equity security is beneficially owned,
     directly or indirectly, by the Corporation.

     "Voting Shares" shall mean shares of all classes and series of the
     Corporation entitled to vote generally in the election of the Corporation's
     directors.

                                      -6-

     NINTH: Whenever a compromise or arrangement is proposed between the
Corporation and its creditors or any class of them and/or between the
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the Corporation under the
provisions of Section 291 the GCL or on the application of trustees in
dissolution or of any receiver or receivers appointed for the Corporation under
the provisions of Section 279 of the GCL, order a meeting of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of the
Corporation, as the case may be, to be summoned in such manner as the said court
directs. If a majority in number representing three fourths in value of the
creditors or class of creditors, and/or of the stockholders or class of
stockholders of the Corporation, as the case may be, agree to any compromise or
arrangement and to any reorganization of the Corporation as a consequence of
such compromise or arrangement, the said compromise or arrangement and the said
reorganization shall, if sanctioned by the court to which the said application
has been made, be binding on all the creditors or class of creditors, and/or on
all the stockholders or class of stockholders, of the Corporation, as the case
may be, and also on the Corporation.

     TENTH: A director of the Corporation shall have no personal liability to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director; provided, however, this Article Tenth shall not eliminate or
limit the liability of a director (i) for any breach of the director's duty of
loyalty to the Corporation or its stockholders, (ii) for acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) under Section 174 of the GCL, or (iv) for any transaction from which
the director derived an improper personal benefit. If the GCL is hereafter
amended to authorize the further elimination or limitation of the liability of
directors, then the liability of a director of the Corporation, in addition to
the limitation on personal liability provided herein, shall be limited to the
fullest extent permitted by the amended GCL. Any repeal or modification of this
Article Tenth by the stockholders of the Corporation shall be prospective only,
and shall not adversely affect any limitation on the personal liability of a
director of the Corporation existing at the time of such repeal or modification.

     ELEVENTH: The Corporation shall have the power to provide indemnification
to the fullest extent permitted by Section 145 of the GCL.

     TWELFTH: The Corporation reserves the right to amend, alter, change or
repeal any provisions contained in this Amended and Restated Certificate of
Incorporation, in the manner now or hereafter prescribed by statute, and all
rights conferred upon stockholders herein are granted subject to this
reservation."

     3. This Amended and Restated Certificate of Incorporation was duly adopted
in accordance with the provisions of Sections 242 and 245 of the GCL by written
consent of a majority of the stockholders outstanding and entitled to vote
thereon in accordance with Section 228 of the GCL.

         SECTION 2.04. SPECIAL MEETING. Special meetings of the stockholders of
the Corporation, for any purpose or purposes, unless otherwise prescribed by
statute or by the Certificate of Incorporation, may be called only by the
Chairman of the Board of Directors of the Corporation or by the Secretary of the
Corporation within ten (10) calendar days after receipt of the written request

         SECTION 2.06. QUORUM. The holders of a majority of the shares of the
Corporation's capital stock issued and outstanding and entitled to vote thereat,
present in person or represented by proxy, shall constitute a quorum at any
meeting of stockholders for the transaction of business, except as otherwise

other provisions of the Certificate of Incorporation or these bylaws, the
holders of a majority of the shares of the Corporation's capital stock entitled
to vote thereat, present in person or represented by proxy, whether or not a
quorum is present, shall have power to adjourn the meeting from time to time,
without notice other than announcement at the meeting, until a quorum shall be

Certificate of Incorporation or of these bylaws, a different vote is required,

such question. Every stockholder having the right to vote shall be entitled to
vote in person, or by proxy appointed by an instrument in writing subscribed by
such stockholder, bearing a date not more than three years prior to voting,
unless such instrument provides for a longer period, and filed with the
Secretary of the corporation before, or at the time of, the meeting. If such
instrument shall designate two or more persons to act as proxies, unless such
instrument shall provide the contrary, a majority of such persons present at any
meeting at which their powers thereunder are to be exercised shall have and may
exercise all the powers of voting or giving consents thereby conferred, or if
only one be present, then such powers may be exercised by that one; or, if an
even number attend and a majority do not agree on any particular


                                       -2-
<PAGE>

issue, each proxy so attending shall be entitled to exercise such powers in
respect of the same portion of the shares as such proxy is of the proxies
representing such shares.

         SECTION 2.08. VOTING OF STOCK OF CERTAIN HOLDERS. Shares of the
Corporation's capital stock standing in the name of another corporation,
domestic or foreign, may be voted by such officer, agent, or proxy as the bylaws
of such corporation may prescribe, or in the absence of such provision, as the
Board of Directors of such corporation may determine. Shares standing in the
name of a deceased person may be voted by the executor or administrator of such
deceased person, either in person or by proxy. Shares standing in the name of a
guardian, conservator, or trustee may be voted by such fiduciary, either in
person or by proxy, but no such fiduciary shall be entitled to vote shares held
in such fiduciary capacity without a transfer of such shares into the name of
such fiduciary. Shares standing in the name of a receiver may be voted by such
receiver. A stockholder whose shares are pledged shall be entitled to vote such
shares, unless in the transfer by the pledgor on the books of the corporation,
the pledgor has expressly empowered the pledgee to vote thereon, in which case
only the pledgee, or his proxy, may represent the stock and vote thereon.

         SECTION 2.09. TREASURY STOCK. The Corporation shall not vote, directly
or indirectly, shares of its own capital stock owned by it; and such shares
shall not be counted in determining the total number of outstanding shares of
the Corporation's capital stock.

         SECTION 2.10. FIXING RECORD DATE. The Board of Directors may fix in
advance a date, which shall not be more than 60 days nor less than 10 days
preceding the date of any meeting of stockholders, nor more than 60 days
preceding the date for payment of any dividend or distribution, or the date for
the allotment of rights, or the date when any change, or conversion or exchange
of capital stock shall go into effect, or a date in connection with obtaining a
consent, as a record date for the determination of the stockholders entitled to
notice of, and to vote at, any such meeting and any adjournment thereof, or
entitled to receive payment of any such dividend or distribution, or to receive
any such allotment of rights, or to exercise the rights in respect of any such
change, conversion or exchange of capital stock, or to give such consent, and in
such case such stockholders and only such stockholders as shall be stockholders
of record on the date so fixed, shall be entitled to such notice of, and to vote
at, any such meeting and any adjournment thereof, or to receive payment of such
dividend or distribution, or to receive such allotment of rights, or to exercise
such rights, or to give such consent, as the case may be, notwithstanding any
transfer of any stock on the books of the Corporation after any such record date
fixed as aforesaid.

                                   ARTICLE III

                               BOARD OF DIRECTORS

         SECTION 3.01. POWERS. The business and affairs of the Corporation shall

         SECTION 3.02. NUMBER, ELECTION AND TERM. The number of directors that
shall constitute the whole Board of Directors shall be not less than one. Such
number of directors shall from time to time be fixed and determined by the
directors and shall be set forth in the notice of any meeting of stockholders
held for the purpose of electing directors. The Board of Directors will be
divided into three classes which will serve staggered three year terms as set
forth in Article Eighth of the Certificate of Incorporation. The directors shall
be elected at the annual meeting of stockholders in the manner provided in
Article Eighth of the Certificate of Incorporation, except as provided in
Section 3.03 hereof, and each director elected shall hold office until his
successor shall be elected and shall qualify. Directors need not be residents of
Delaware or stockholders of the Corporation.

         SECTION 3.03. VACANCIES, ADDITIONAL DIRECTORS, AND REMOVAL FROM OFFICE.
If any vacancy occurs in the Board of Directors caused by death, resignation,
retirement, disqualification, or removal from office of any director, or
otherwise, or if any new directorship is created by an increase in the
authorized number of directors, a majority of the directors then in office,
though less than a quorum, or a sole remaining director, may choose a successor
or fill the newly created directorship; and a director so chosen shall hold
office until the next election and until his successor shall be duly elected and
shall qualify, unless sooner displaced. Directors may only be removed in
accordance with Article Eighth of the Certificate of Incorporation.

Directors shall be held each year, without other notice than this bylaw, at the

within or without the State of Delaware, without other notice than such
resolution.

Directors may be called by the Chairman of the Board of Directors or by the

directors so requesting, any such meeting shall fix the time and any place,
either within or without the State of Delaware, as the place for holding such
meeting.

         SECTION 3.06. NOTICE OF SPECIAL MEETING. Written notice of special
meetings of the Board of Directors shall be given to each director in a manner
reasonably calculated to reach such director at least 48 hours prior to the time
of such meeting. Any director may waive notice of any meeting. The attendance of
a director at any meeting shall constitute a waiver of notice of such meeting,
except where a director attends a meeting for the purpose of objecting to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
special meeting of the Board of Directors need be specified in the notice or
waiver of notice of such meeting, except that notice shall be given of any
proposed amendment to the bylaws if it is to be adopted at any special meeting
or with respect to any other matter where notice is required by statute.

         SECTION 3.07. QUORUM. A majority of the Board of Directors shall
constitute a quorum for the transaction of business at any meeting of the Board
of Directors, and the act of a majority of the directors present at any meeting
at which there is a quorum shall be the act of the Board of Directors, except as
may be otherwise specifically provided by statute, by the Certificate of
Incorporation or by these bylaws. If a quorum shall not be present at any
meeting of the Board of Directors, the directors present thereat may adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present.

         SECTION 3.08. ACTION WITHOUT MEETING. Unless otherwise restricted by
the Certificate of Incorporation or these bylaws, any action required or
permitted to be taken at any meeting of the Board of Directors, or of any
committee thereof as provided in Article IV of these bylaws, may be taken

consent is filed with the minutes of proceedings of the Board of Directors or
such committee.

         SECTION 3.09. COMPENSATION. Directors, as such, shall not be entitled
to any stated salary for their services unless voted by the stockholders or the
Board of Directors; but by resolution of the Board of Directors, a fixed annual
retainer and a fixed sum and expenses of attendance may be allowed for
attendance at each regular or special meeting of the Board of Directors or any
meeting of a committee of directors and equity incentive awards may be granted.
No provision of these bylaws shall be construed to preclude any director from
serving the Corporation in any other capacity and receiving compensation
therefor.

         SECTION 3.10. MANDATORY RETIREMENT. Directors shall be required to
retire from the Board of Directors of the Corporation upon reaching the age of

Board of Directors may designate one or more directors as alternate members of
any committee, who may replace any absent or disqualified member at any meeting
of such committee. In the absence or disqualification of any member of such
committee or committees, the member or members thereof present at any meeting
and not disqualified from voting, whether or not such member or members
constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of any such absent or disqualified
member. Such committee or committees shall have such name or


                                       -5-

Executive Officer shall preside at all meetings of the Board of Directors and of

                         CONTRACTS, CHECKS AND DEPOSITS


         SECTION 7.01. CONTRACTS. Subject to the provisions of Section 6.01, the
Board of Directors may authorize any officer, officers, agent, or agents, to
enter into any contract or execute and deliver any instrument in the name of and
on behalf of the Corporation, and such authority may be general or confined to
specific instances.

         SECTION 7.02. CHECKS. All checks, demands, drafts, or other orders for
the payment of money, notes, or other evidences of indebtedness issued in the
name of the Corporation, shall be signed by such officer or officers or such

by the Board of Directors.

         SECTION 7.03. DEPOSITS. All funds of the Corporation not otherwise

in such banks, trust companies, or other depositories as the Board of Directors

                                  ARTICLE VIII

                              CERTIFICATES OF STOCK

         SECTION 8.01. ISSUANCE. Each stockholder of this Corporation shall be
entitled to a certificate or certificates showing the number of shares of
capital stock registered in his name on the books of the Corporation. The
certificates shall be in such form as may be determined by the Board of
Directors, shall be issued in numerical order and shall be entered in the books
of the Corporation as they are issued. They shall exhibit the holder's name and
number of shares and shall be signed by the Chief Executive Officer, the
President or a Vice President and by the Secretary or an Assistant Secretary. If
any certificate is countersigned (1) by a transfer agent other than the
Corporation or any employee of the Corporation, or (2) by a registrar other than
the Corporation or any employee of the Corporation, any other signature on the
certificate may be a facsimile. If the Corporation shall be authorized to issue
more than one class of stock or more than one series of any class, the
designations, preferences, and relative participating, optional, or other
special rights of each class of stock or series thereof and the qualifications,
limitations, or restrictions of such preferences and rights shall be set forth
in full or summarized on the face or back of the certificate which the
Corporation shall issue to represent such class of stock; provided that, except
as otherwise provided by statute, in lieu of the foregoing requirements there
may be set forth on the face or back of the certificate which the Corporation
shall issue to represent such class or series of stock, a statement that the
Corporation will furnish to each stockholder who so requests the designations,
preferences and relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations, or
restrictions of such preferences and rights. All certificates surrendered to the
Corporation for transfer shall be canceled and no new certificate shall be
issued until the former certificate for a like number of shares shall have been
surrendered and canceled, except that in the case of a lost, stolen, destroyed,
or mutilated certificate a new one may


                                      -10-
<PAGE>

be issued therefor upon such terms and with such indemnity, if any, to the
Corporation as the Board of Directors may prescribe. Certificates shall not be
issued representing fractional shares of stock.

         SECTION 8.02. LOST CERTIFICATES. The Board of Directors may direct a
new certificate or certificates to be issued in place of any certificate or
certificates theretofore issued by the Corporation alleged to have been lost,
stolen, or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed. When
authorizing such issue of a new certificate or certificates, the Board of
Directors may, in its discretion and as a condition precedent to the issuance
thereof, require (1) the owner of such lost, stolen, or destroyed certificate or
certificates, or his legal representative, to advertise the same in such manner
as it shall require, (2) such owner to give the Corporation a bond in such sum
as it may direct as indemnity against any claim that may be made against the
Corporation with respect to the certificate or certificates alleged to have been
lost, stolen, or destroyed, or (3) both.

         SECTION 8.03. TRANSFERS. Upon surrender to the Corporation or the
transfer agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment, or authority to
transfer, it shall be the duty of the Corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate, and record the
transaction upon its books. Transfers of shares shall be made only on the books
of the Corporation by the registered holder thereof, or by his attorney
thereunto authorized by power of attorney and filed with the Secretary of the
Corporation or the Transfer Agent.

         SECTION 8.04. REGISTERED STOCKHOLDERS. The Corporation shall be
entitled to treat the holder of record of any share or shares of the
Corporation's capital stock as the holder in fact thereof and, accordingly,
shall not be bound to recognize any equitable or other claim to or interest in
such share or shares on the part of any other person, whether or not it shall
have express or other notice thereof, except as otherwise provided by the laws
of the State of Delaware.

                                   ARTICLE IX

                                    DIVIDENDS

         SECTION 9.01. DECLARATION. Dividends with respect to the shares of the
Corporation's capital stock, subject to the provisions of the Certificate of
Incorporation, if any, may be declared by the Board of Directors at any regular
or special meeting, pursuant to applicable law. Dividends may be paid in cash,
in property, or in shares of capital stock, subject to the provisions of the
Certificate of Incorporation.

         SECTION 9.02. RESERVE. Before payment of any dividend, there may be set
aside out of any funds of the Corporation available for dividends such sum or
sums as the Board of Directors from time to time, in their absolute discretion,
think proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the Corporation, or
for such other purpose as the Board of Directors shall think conducive to the
interest


                                      -11-
<PAGE>

of the Corporation, and the Board of Directors may modify or abolish any such
reserve in the manner in which it was created.

                                    ARTICLE X

                                 INDEMNIFICATION

         SECTION 10.01. THIRD PARTY ACTIONS. The Corporation shall indemnify any
director or officer of the Corporation, and may indemnify any other person, who
was or is a party or is threatened to be made a party to any threatened,
pending, or completed action, suit, or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the
Corporation) by reason of the fact that the person is or was a director,
officer, employee, or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, employee, or agent of another
corporation, partnership, joint venture, trust, or other enterprise, against
expenses (including attorneys' fees), judgments, fines, and amounts paid in
settlement actually and reasonably incurred by the person in connection with
such action, suit, or proceeding if the person acted in good faith and in a
manner the person reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the person's conduct was
unlawful. The termination of any action, suit, or proceeding by judgment, order,
settlement, or conviction, or upon a plea of NOLO CONTENDERE or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which the person reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that the person's
conduct was unlawful.

         SECTION 10.02. ACTIONS BY OR IN THE RIGHT OF THE CORPORATION. The
Corporation shall indemnify any director or officer and may indemnify any other
person who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action or suit by or in the right of the
Corporation to procure a judgment in its favor by reason of the fact that the
person is or was a director, officer, employee, or agent of the Corporation, or
is or was serving at the request of the Corporation as a director, officer,
employee, or agent of another corporation, partnership, joint venture, trust, or
other enterprise against expenses (including attorneys' fees) actually and
reasonably incurred by the person in connection with the defense or settlement
of such action or suit if the person acted in good faith and in a manner the
person reasonably believed to be in or not opposed to the best interests of the
Corporation and except that no indemnification shall be made in respect of any
claim, issue, or matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses as the Court of Chancery or such other court shall
deem proper.

         SECTION 10.03. MANDATORY INDEMNIFICATION. To the extent that a
director, officer, employee, or agent of the Corporation has been successful on
the merits or otherwise in defense of


                                      -12-
<PAGE>

any action, suit, or proceeding referred to in Sections 10.01 and 10.02, or in
defense of any claim, issue, or matter therein, such person shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
such person in connection therewith.

         SECTION 10.04. DETERMINATION OF CONDUCT. Any indemnification under
Section 10.01 or 10.02 of this Article X (unless ordered by a court) shall be
made by the Corporation only as authorized in the specific case upon a
determination that indemnification of the director, officer, employee or agent
is proper in the circumstances because the person has met the applicable
standard of conduct set forth in Section 10.01 or 10.02 of this Article X. Such
determination shall be made (a) by a majority vote of directors who were not
parties to such action, suit or proceeding, even though less than a quorum, or
(b) if there are no such directors, or if such directors so direct, by
independent legal counsel in a written opinion, or (c) by the stockholders.

         SECTION 10.05. PAYMENT OF EXPENSES IN ADVANCE. Expenses (including
attorneys' fees) incurred in defending a civil or criminal action, suit, or
proceeding may be paid by the Corporation in advance of the final disposition of
such action, suit, or proceeding upon receipt of an undertaking by or on behalf
of the director, officer, employee, or agent to repay such amount if it shall
ultimately be determined that the person is not entitled to be indemnified by
the Corporation as authorized in this Article X.

         SECTION 10.06. INDEMNITY NOT EXCLUSIVE. The indemnification and
advancement of expenses provided or granted hereunder shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under the Certificate of Incorporation,
any other bylaw, agreement, vote of stockholders, or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office.

         SECTION 10.07. DEFINITIONS. For purposes of this Article X:

                  (a) "the Corporation" shall include, in addition to the
         resulting corporation, any constituent corporation (including any
         constituent of a constituent) absorbed in a consolidation or merger
         that, if its separate existence had continued, would have had power and
         authority to indemnify its directors, officers, and employees or
         agents, so that any person who is or was a director, officer, employee,
         or agent of such constituent corporation, or is or was serving at the
         request of such constituent corporation as a director, officer,
         employee, or agent of another corporation, partnership, joint venture,
         trust, or other enterprise, shall stand in the same position under this
         Article X with respect to the resulting or surviving corporation as the
         person would have with respect to such constituent corporation if its
         separate existence had continued;

                  (b) "other enterprises" shall include employee benefit plans;

                  (c) "fines" shall include any excise taxes assessed on a
         person with respect to any employee benefit plan;


                                      -13-
<PAGE>

                  (d) "serving at the request of the Corporation" shall include
         any service as a director, officer, employee, or agent of the
         Corporation that imposes duties on, or involves services by, such
         director, officer, employee, or agent with respect to an employee
         benefit plan, its participants or beneficiaries; and

                  (e) a person who acted in good faith and in a manner such
         person reasonably believed to be in the interest of the participants
         and beneficiaries of an employee benefit plan shall be deemed to have
         acted in a manner "not opposed to the best interests of the
         Corporation" as referred to in this Article X.

         SECTION 10.08. CONTINUATION OF INDEMNITY. The indemnification and
advancement of expenses provided or granted hereunder shall, unless otherwise
provided when authorized or ratified, continue as to a person who has ceased to
be a director, officer, employee, or agent and shall inure to the benefit of the
heirs, executors, and administrators of such a person.

                                   ARTICLE XI

                                  MISCELLANEOUS

         SECTION 11.01. SEAL. The corporate seal, if one is authorized by the

to any provision contained in the statutes) outside the State of Delaware at the
offices of the Corporation, or at such other place or places as may be

                                    AMENDMENT

            AGREEMENT OF LEASE made as of this 6th day of January, 1984, between
AETNA LIFE INSURANCE COMPANY, a Connecticut corporation having an address at One
Civic Center Plaza, P.O. Box 1414, Hartford, Connecticut 06143 (hereinafter
referred to as "Landlord") and LA BRANCHE & CO., a New York partnership having
an address at 30 Broad Street, New York, New York 10004 (hereinafter referred to
as "Tenant").

                              W I T N E S S E T H:

            Landlord hereby leases and Tenant hereby rents from Landlord the
easterly portion of the 26th floor shown hatched on the plan annexed hereto as
Schedule A (the "demised premises") in the building (the "Building") constructed
by Landlord on the land (the "Land") described in Schedule B annexed hereto (the
Land and the Building being hereinafter referred to as the "Property"), for a
term (the "Term") of ten (10) years commencing on the "Commencement Date" and
ending on the "Expiration Date" (as said terms are defined in Article 2 hereof)
unless the Term shall sooner cease and terminate as hereinafter provided. It is
understood and agreed that the Building has no 13th floor.

            The parties hereby covenant and agree as follows:

                                    ARTICLE 1

                                      RENT

            1.01. Tenant agrees to pay to Landlord a fixed annual rent (the
"fixed annual rent") at the annual rate of ONE HUNDRED FORTY-SEVEN THOUSAND
EIGHT HUNDRED EIGHTY-NINE & 00/100 ($147,889.00) DOLLARS in equal monthly
installments of TWELVE THOUSAND THREE HUNDRED TWENTY-FOUR & 08/100) ($12,324.08)
DOLLARS each in advance on the first day of each calendar month during the Term,
at the office of Landlord or such other place as Landlord may designate, without
any setoff or deduction whatsoever, except such deductions as are specifically
referred to in Articles 10 and 14 hereof. The first full month's installment of
fixed annual rent and the Security Deposit described in Article 41 hereof shall
be paid by Tenant to Landlord upon the execution of this Lease. Should the
Commencement Date fall on any day other than the first day of a month, then the


                                       1
<PAGE>

fixed annual rent for such month shall be prorated on a per diem basis, and
Tenant agrees to pay the amount thereof for such partial month on the
Commencement Date.

            1.02. Tenant shall pay the fixed annual rent and all additional rent
payable hereunder in lawful money of the United States by check (subject to
collection) drawn to the order of Jones Lang Wootton - One Exchange, or such
other party as Landlord may from time to time designate, on a bank which is a
member of the New York Clearinghouse Association or a successor thereto. All
sums, other than fixed annual rent, payable by Tenant hereunder shall be deemed
additional rent and shall be payable on demand unless other payment dates are
hereinafter provided. Landlord shall have the same right and remedies
(including, without limitation, the right to commence a summary proceeding) for
a default in the payment of additional rent as for a default in the payment of
fixed annual rent notwithstanding the fact that Tenant may not then also be in
default in the payment of fixed annual rent.

            1.03. If Tenant shall fail to pay when due any installment of fixed
annual rent or any payment of additional rent for a period of 7 days after such
installment or payment shall have become due, Tenant shall pay interest thereon
at the Interest Rate (as such term is defined in Article 22 hereof), from the
date when such installment or payment shall have become due to the date of the
payment thereof, and such interest shall be deemed additional rent. The
provisions of this Section 1.03 are in addition to all other remedies available
to Landlord for nonpayment of fixed annual rent or additional rent.

            1.04. If any of the fixed annual rent or additional rent payable
under this Lease shall be or become uncollectible, reduced or required to be
refunded because of any Legal Requirement (as such term is defined in Article 22
hereof), Tenant shall enter into such agreement(s) and take such other legally
permissible steps as Landlord may request to permit Landlord to collect the
maximum rents which from time to time during the continuance of such Legal
Requirement may be legally permissible and not in excess of the amounts reserved
therefor under this Lease. Upon the termination of such Legal Requirement, (a)
the rents hereunder shall be payable in the amounts reserved herein for the
periods following such termination and (b) Tenant shall pay to Landlord, to the
maximum extent legally permissible, an amount equal to (i) the rents which would
have been paid pursuant to this Lease but for such Legal Requirements less (ii)
the rents paid by Tenant during the period such Legal Requirement was in effect.

                                    ARTICLE 2

                              COMMENCEMENT OF TERM

            2.01. (a) The "Commencement Date" of the Term shall be the earlier
of (i) the date on which the demised premises are substantially ready for
occupancy (as defined below), or (ii) the date Tenant or anyone claiming under
or through Tenant first occupies the demised premises for the conduct of its
business.

                  (b) The "Expiration Date" of the Term shall be the last day of
the month in which the tenth anniversary of the Commencement Date occurs or such
later date as shall be specified by Landlord pursuant to Section 2.06 below.

            2.02. The demised premises shall be completed and prepared for
Tenant's occupancy as provided in Schedule C annexed hereto. The facilities,
materials and work so to be furnished, installed and performed in the demised
premises by Landlord at its expense are hereinafter and in Schedule C referred
to as the "Building Standard Work." All other installations, materials and work
which may be undertaken by Landlord for the account of Tenant to prepare, equip,
decorate and furnish the demised premises for Tenant's occupancy shall be at
Tenant's expense and are hereinafter and in Schedule C called "Tenant's Extra
Work". Building Standard Work and Tenant's Extra Work are herein and in Schedule
C collectively called "Landlord's Work." Any installations, materials and work
undertaken by Tenant (in the circumstances herein permitted) to prepare, equip,
decorate and furnish the demised premises for Tenant's occupancy shall be at
Tenant's expense and are hereinafter and in Schedule C called "Tenant's Special
Work".

            2.03. The demised premises shall be deemed substantially ready for
occupancy when the Building Standard Work (or so much thereof as Tenant shall
require) shall have been substantially completed and a Certificate of Occupancy
(temporary or final) shall have been issued by the Department of Buildings of
the City of New York permitting use of the demised premises for the purposes
permitted by Article 5 hereof. The Building Standard Work (or so much thereof as
Tenant shall require) shall be deemed to have been substantially completed
notwithstanding that (i) minor or insubstantial details of construction,
decoration or mechanical adjustment remain to be performed, provided the demised
premises are accessible and reasonably useable and (ii) portions thereof are
incomplete which under good


                                       3
<PAGE>

construction scheduling practice should be done after still incomplete Tenant's
Extra Work or Tenant's Special Work. Landlord shall diligently complete all such
portions of Building Standard Work as soon as reasonably practicable.

            2.04. Notwithstanding anything to the contrary contained in this
Lease, the Commencement Date shall be deemed to have occurred on the date when
the demised premises would have been, in Landlord good faith judgment,
substantially ready for occupancy except for (i) Tenant's delay in complying
with, or failure to comply with, the provisions of Schedule C hereof or (ii) any
Tenant's Delay as defined in Schedule C hereof including, without limitation,
any request by Tenant for Tenant's Extra Work, even though no Certificate of
Occupancy (temporary or final) has been issued or the Building Standard Work
being done for Tenant has not been commenced or completed.

            2.05. Landlord shall, in accordance with the foregoing, fix the
Commencement Date and shall notify Tenant of the date so fixed. When the
Commencement Date has so been determined, the parties shall within fifteen (15)
days thereafter, at Landlord's request, execute a written agreement confirming
such date as the Commencement Date. Any failure of the parties to execute such
written agreement shall not affect the validity of the Commencement Date as
fixed and determined by Landlord as aforesaid.

            2.06. Notwithstanding anything contained to the contrary in this
Lease, Landlord at its option, upon written notice from Landlord to Tenant given
within nine (9) months after the Commencement Date is fixed, may extend the Term
as follows: (i) to a date occurring no later than one year beyond the date the
Term would have expired absent the right to extend the Term pursuant to this
Section 2.06 and/or (ii) in the event of any Tenant's Delay for the number of
days equal to the number of days of Tenant's Delay.

            2.07. Notwithstanding anything to the contrary in this Lease,
Landlord shall not be entitled to collect nor shall Tenant be required to pay
fixed annual rent for the period commencing on the Commencement Date and
continuing for 59 days thereafter. All of the other terms, provisions and
conditions contained in this Lease shall apply with full force and effect during
said two-month period.

                                    ARTICLE 3

                               ADJUSTMENTS OF RENT

            3.01. A. For purposes hereof, the following definitions shall apply:

                  (a) The term "Base Tax" shall mean the sum of $1,179,200.00.

                  (b) The term "Tax Year" shall mean each period of twelve
months which includes any part of the Term which now or hereafter is or may be
duly adopted as the fiscal year for real estate tax purposes of the City of New
York.

                  (c) The term "Taxes" shall mean (i) all real estate taxes,
assessments, governmental levies, municipal taxes, county taxes or any other
governmental charge, general or special, ordinary or extraordinary, unforeseen
as well as foreseen, of any kind or nature whatsoever, which are or may be
assessed, levied or imposed upon all or any part of the Property and the
sidewalks, plazas or streets adjacent thereto, including any tax, excise or fee
measured by or payable with respect to any rent (other than any occupancy or
rent tax payable by Tenant pursuant to Section 3.03), and levied against
Landlord and/or the Property under the laws of the United States, the City or
State of New York, or any political subdivision thereof, and (ii) any expenses
incurred by Landlord, including payments to attorneys and appraisers, in
contesting any of the items set forth in clause (i) of this sentence, or the
assessed valuations of all or any part of the Property. If due to a future
change in the method of taxation or in the taxing authority, a new or additional
real estate tax, or a franchise, income, transit, profit or other tax or
governmental imposition, however designated, shall be levied against Landlord,
and/or the Property, in addition to, or in substitution in whole or in part for
any tax which would constitute "Taxes", or in lieu of additional Taxes, such tax
or imposition shall be deemed for the purposes hereof to be included within the
term "Taxes."

                  (d) The term "Tenant's Tax Share" shall mean 1.36%.

                  (e) The term "Escalation Statement" shall mean a statement
setting forth the amount payable by Tenant for a specified Tax Year or Operating
Year (as defined in


                                        5
<PAGE>

Section 3.02 hereof), as the case may be, or for some portion thereof pursuant
to this Article 3.

                  B. Tenant shall pay to Landlord as additional rent for each
Tax Year a sum equal to Tenant's Tax Share of the amount by which the Taxes for
such Tax Year exceed the Base Tax (hereinafter referred to as "Tenant's Tax
Payment"). Landlord shall furnish the Tenant an annual Escalation Statement
(subject to revision as hereinafter provided) for each Tax Year setting forth
Tenant's Tax Payment for such Tax Year. Tenant's Tax Payment shall be due and
payable as follows: two semi-annual installments, in advance, on the first day
of each June and December of each calendar year. If an annual Escalation
Statement is furnished to the Tenant after the commencement of the Tax Year to
which it relates, then (a) until such Escalation Statement is rendered, Tenant
shall pay Tenant's Tax Payment for such Tax Year in installments based upon the
last Escalation Statement rendered to Tenant with respect to Taxes and (b)
Tenant shall, within 20 days after such annual Escalation Statement is furnished
to Tenant, pay to Landlord an amount equal to any underpayment of the
installments of Tenant's Tax Payment theretofore paid by Tenant for such Tax
Year and, in the event of an overpayment by Tenant, Landlord shall permit Tenant
to credit against subsequent payments under this Section 3.01 the amount of such
overpayment. If there shall he any increase in Taxes for any Tax Year, whether
during or after such Tax Year, Landlord shall furnish a revised Escalation
Statement for such Tax Year to Tenant, and Tenant's Tax Payment for such Tax
Year shall be adjusted and paid or credited, as appropriate, in the same manner
as provided in the preceding sentence. If during the Term, Taxes are required to
be paid (either to the appropriate taxing authorities or as tax escrow payments
to a superior mortgagee or ground lessor) in full or in monthly, quarterly, or
other installments, on any other date or dates than as presently required, then
at Landlord's option, Tenant's Tax Payments shall be correspondingly accelerated
or revised so that said Tenant's Tax Payments are due at least 30 days prior to
the date payments are due to the taxing authorities or the superior mortgagee or
ground lessor. The benefit of any discount for any early payment or prepayment
of Taxes shall accrue solely to the benefit of Landlord and such discount shall
not be subtracted from Taxes.

                  C. If Landlord shall receive a refund of Taxes for any Tax
Year, Landlord shall permit Tenant to credit against subsequent payments under
this Section 3.01, Tenant's Tax Share of the refund, but not in excess of,
Tenant's Tax Payment paid for such Tax Year.

            3.02. A. For purposes hereof the following definitions shall apply:

                  (a) The term "Expense Base Factor" shall mean $1,136,200.00.

                  (b) The term "Operating Year" shall mean each calendar year
which includes any part of the Term.

                  (c) The terms "Tenant's Expense Share" shall mean 1.41%.

                  (d) The term "Expenses" shall mean the total of all the costs
and expenses (and taxes thereon, if any) incurred by Landlord with respect to
the operation and maintenance of the Property and the services provided to the
tenants of the Building computed on an accrual basis including, without
limitation, the costs and expenses with respect to: steam, gas and any other
fuel or utilities; water rates and sewer rents; air conditioning for areas other
than those leased to individual Tenants; ventilation and heating; electricity
for areas other than those leased to individual Tenants as indicated by meter,
or if there be no meter, as determined by Landlord's electrical consultant (as
defined in Section 3.08 hereof); elevators and escalators; metal, elevator cab,
lobby, plaza, sidewalk, curb and other public area maintenance and cleaning;
interior and exterior landscaping and decoration; painting of non-tenant areas;

cleaning supplies, tools, materials, machinery and equipment; depreciation of
hand tools and other movable equipment used in the operation or maintenance of
the Property; fire, extended coverage, boiler and machinery, sprinkler

plate glass insurance and any other insurance required by the holder of any
mortgage or ground lease covering the Property or customarily carried with
respect to buildings similar to the Building; wages, salaries, bonuses,
disability benefits, hospitalization, medical, surgical, union and general
welfare benefits (including group life insurance), any pension, retirement or
life insurance plan and other benefit or similar expense respecting employees of
the Landlord up to and including the building manager; uniforms and working
clothes for such employees and the cleaning and replacement thereof; expenses
imposed on the Landlord pursuant to law or to any collective bargaining
agreement with respect to such employees; workmen's compensation insurance,
payroll, social security, unemployment and other similar taxes with respect to

                                       7
<PAGE>

employees; salaries of bookkeepers and accountants; professional and consulting
fees, including legal and accounting fees; charges for independent contractors
performing work included within the definition of Expenses; association fees or
dues; telephone and stationery; guards, watchmen, and other security personnel
services and/or systems; directory; building telephone; repairs, replacements
and improvements which are necessary or appropriate for the continued operation
of the Building as a first-class office building; and management fees for the
management of the Building, or if no managing agent is employed by Landlord
(i.e. Landlord performs such management services itself), a sum in lieu thereof
which is not in excess of the then prevailing rates for management fees in the
Borough of Manhattan for first-class office buildings similar to the building.

            The following costs and expenses shall be excluded or deducted, as
appropriate, from the foregoing costs and expenses:

                        (i) the cost of electricity furnished to the demised
premises and other space leased to tenants as measured by meters, or if there be
no meters, as determined by Landlord's electrical consultant;

                        (ii) leasing commissions;

                        (iii) salaries for Landlord's executives above the grade
of building manager;

                        (iv) amounts received by Landlord through proceeds of
insurance to the extent the proceeds are compensation for expenses which were
previously included in Expenses hereunder;

                        (v) cost of repairs or replacements incurred by reason
of fire or other casualty or condemnation to the extent to which Landlord is
compensated therefor through proceeds of insurance or condemnation award;

                        (vi) advertising and promotional expenditures other than
for prospective employees of the Landlord (which expenditures shall be included
within the definition of Expenses);

                        (vii) Taxes;

                        (viii) costs for performing Landlord's Work for any
individual Tenant or for performing work or


                                        8
<PAGE>

furnishing services to or for individual tenants at such tenant's expense; and

                        (ix) expenditures for capital improvements except those
which under generally applied real estate practice are expensed or regarded as
deferred expenses and except for capital expenditures required by law, in either
of which cases the cost thereof shall be included in Expenses for the Operating
Year in which the costs are incurred and subsequent Operating Years, on a
straight line basis, to the extent that such items are amortized over an
appropriate period, but not more than ten years, with interest at the Interest
Rate.

            If Landlord shall purchase any item of capital equipment or make any
capital expenditures designed to result in savings or reductions in Expenses,
then the costs for same shall be included in Expenses. The costs of capital
equipment or capital expenditures are so to be included in Expenses for the
Operating Year in which the costs are incurred and subsequent Operating Years,
on a straight line basis, to the extent that such items are amortized over such
period of time as reasonably can be estimated as the time in which such savings
or reductions in Expenses are expected to equal Landlord's costs for such
capital equipment or capital expenditure, with interest at the Interest Rate. If
Landlord shall lease any such item of capital equipment designed to result in
savings or reductions in Expenses, then the rentals and other costs paid
pursuant to such leasing shall be included in Expenses for the Operating Year in
which they were incurred.

            If during all or part of any Operating Year, Landlord shall not
furnish any particular item(s) of work or service (which would constitute an
Expense hereunder) to portions of the Building, due to the fact that
construction of the Building is not completed, or such portions are not occupied
or leased, or because such item of work or service is not required or desired by
the tenant of such portion, or such tenant is itself obtaining and providing
such item of work or service, or for other reasons, then, for the purpose of
computing the additional rent payable hereunder, the amount of the Expenses for
such item for such period shall be increased by an amount equal to the
additional operating and maintenance expenses which would reasonably have been
incurred during such period by Landlord if it had at its own expense furnished
such item of work or services to such portion of the Building.

                  B. If the Expenses for any Operating Year exceed the Expense
Base Factor, Tenant shall pay to Landlord


                                       9
<PAGE>

as additional rent for such Operating Year an amount equal to Tenant's Expense
Share of the excess of the Expenses for such Operating Year over the Expense
Base Factor (hereinafter referred to as "Tenant's Expense Payment").

                  C. Landlord shall furnish to Tenant for each Operating Year an
Escalation Statement (subject to revision as hereinafter provided) setting forth
Landlord's estimate of Tenant's Expense Payment for such Operating Year. Tenant
shall pay to Landlord on the first day of each month during such Operating Year
an amount equal to one-twelfth (1/12) of Landlord's estimate of Tenant's Expense
Payment for such Operating Year. If Landlord shall furnish such estimate for an
Operating Year after the commencement thereof, then (a) until the first day of
the month following the month in which such estimate is furnished to Tenant,
Tenant shall pay to Landlord on the first day of each month an amount equal to
the monthly sum payable by Tenant to Landlord under this Paragraph C for the
last month of the preceding Operating Year; (b) Landlord shall notify Tenant in
the Escalation Statement containing such estimate whether the installments of
Tenant's Expense Payment previously paid for such Operating Year were more or
less than the installments which should have been paid for such Operating Year
pursuant to such estimate and (i) if there shall be an underpayment, Tenant
shall pay the amount thereof within ten days after being furnished with such
Escalation Statement or (ii) if there shall be an overpayment, Tenant shall be
entitled to a credit in the amount thereof against subsequent payments under
this Section 3.02; and (c) on the first day of the month following the month in
which such estimate is furnished to Tenant and monthly thereafter for the
balance of such Operating Year, Tenant shall pay to Landlord an amount equal to
one-twelfth (1/12) of Tenant's Expense Payment as shown on such estimate.
Landlord may at any time and from time to time (but not more often than three
times in any Operating Year) furnish to Tenant an Escalation Statement setting
forth Landlord's revised estimate of Tenant's Expense Payment for a particular
Operating Year and Tenant's Expense Payment for such Operating Year shall be
adjusted and paid or credited, as applicable, in the same manner as provided in
the preceding sentence.

                  D. After the end of each Operating Year Landlord shall submit
to Tenant an annual Escalation Statement prepared by Landlord setting forth the
Expenses for the preceding Operating Year and the balance of Tenant's Expense
Payment, if any, due to Landlord from Tenant for such Operating Year. If such
annual Escalation Statement shall show that the sums paid by Tenant under
subparagraph 3.02(C) above exceeded Tenant's Expense Payment for such


                                       10
<PAGE>

Operating Year, Tenant shall be entitled to a credit in the amount of such
excess against subsequent payments under this Section 3.02. If such annual
Escalation Statement shall show that the sums so paid by Tenant were less than
Tenant's Expense Payment for such Operating Year, Tenant shall pay the amount of
such deficiency to the Landlord within ten days after being furnished with such
annual Escalation Statement.

                  E. The annual Escalation Statements with respect to Expenses
to be furnished by Landlord as provided above shall be in reasonable detail and
shall be certified by Landlord or by an independent firm of certified public
accountants. Landlord may use operating cost allocations and estimates if such
allocations or estimates are required for this Section 3.02.

            3.03. Tenant shall pay to Landlord upon demand, as additional rent,
any occupancy tax or rent tax now in effect or hereafter enacted, which Landlord
is now or hereafter is required to pay with respect to the demised premises or
this Lease.

            3.04. If the Commencement Date shall be other than the first day of
a Tax Year or an Operating Year or if the date of the expiration or other
termination of this Lease shall be a day other than the last day of a Tax Year
or an Operating Year, then Tenant's Tax Payment and/or Tenant's Expense Payment
for such partial year shall be equitably adjusted taking into consideration the
portion of such Tax Year or Operating Year falling within the Term. Landlord
shall, as soon as reasonably practicable, cause an Escalation Statement with
respect to Taxes for the Tax Year and/or Expenses for the Operating Year in
which the Term expires to be prepared and furnished to Tenant. Such Escalation
Statement shall be prepared as of the expiration date of the Term if such date
is December 31, and if not, as of the first to occur of June 30 or December 31
after the expiration date of the Term. Landlord and Tenant shall thereupon make
appropriate adjustments of amounts then owing and notwithstanding anything to
the contrary contained herein in the event any amount shall be due and owing
from Landlord to Tenant upon the expiration of or termination of the Term (other
than by reason of Tenant's default), such amount shall be refunded rather than
credited against any further rent obligations hereunder simultaneously with the
rendering of the final Escalation Statement.

            3.05. In no event shall the fixed annual rent ever be reduced by
operation of this Article 3. The rights and obligations of Landlord and Tenant
under the provisions


                                       11
<PAGE>

of this Article 3 shall survive the termination of this Lease, and payments
shall be made pursuant to this Article 3 notwithstanding the fact that an
Escalation Statement is furnished to Tenant after the expiration or other
termination of the Term.

            3.06. Landlord's failure to render an Escalation Statement with
respect to any Tax Year or Operating Year shall not prejudice Landlord's right
to thereafter render an Escalation Statement with respect thereto or with
respect to any subsequent Tax Year or Operating Year.

            3.07. Each Escalation Statement shall be conclusive and binding upon
Tenant unless within 10 days after receipt of such Escalation Statement Tenant
shall notify Landlord that it disputes the correctness of such Escalation
Statement, specifying the particular respects in which such Escalation Statement
is claimed to be incorrect. Any dispute relating to any Escalation Statement,
not resolved within 30 days after the giving of such notice by Tenant, may be
submitted to arbitration by either party pursuant to Article 37 hereof. Pending
the determination of such dispute, Tenant shall pay additional rent in
accordance with the Escalation Statement that Tenant is disputing, without
prejudice to Tenant's position.

            3.08. Any determinations with respect to charges for electricity on
floors occupied by more than one tenant or otherwise which must be made pursuant
to the terms of this Lease shall be made by a reputable, independent electrical
consultant selected by Landlord (Landlord's "electrical consultant"). Any
determination made by Landlord's electrical consultant pursuant to or in
connection with this Lease shall be binding and conclusive on Landlord and on
Tenant.

                                    ARTICLE 4

                                   ELECTRICITY

            4.01. Landlord agrees that prior to the Commencement Date risers,
feeders and wiring will be installed in the Building by Landlord to furnish
electrical service to the demised premises in accordance with the provisions of
the Work Agreement annexed hereto as Schedule C. After the Commencement Date any
additional risers, feeders or other equipment or service proper or necessary to
supply Tenant's electrical requirements, upon written


                                       12
<PAGE>

request of Tenant, will be installed by Landlord at the sole cost and expense of
Tenant, if in Landlord's sole judgment the same are necessary and will not cause
permanent damage or injury to the Building or the demised premises or cause or
create a dangerous or hazardous condition or entail excessive or unreasonable
alterations, repairs or expense or interfere with or disturb other tenants or
occupants.

            4.02. Tenant covenants and agrees to pay directly to the utility
company supplying electricity to the demised premises the amounts due for
electric current consumed by Tenant as indicated by meters measuring Tenant's
consumption thereof.

            4.03. If one meter measures the consumption of electric current by
Tenant and another lessee of space in the Building (i.e., more than one tenant
on a floor), or if there is no meter measuring Tenant's consumption of electric
current for any purpose, including without limitation, air conditioning,
ventilating and heating, Tenant agrees to pay to Landlord or Landlord's
designated agent charges for electric current consumed by Tenant as determined
by Landlord's electric consultant in accordance with Section 3.08 above. Bills
therefor, at the rate charged to Landlord for such electric current, plus the
amount of sales tax imposed thereon by any Governmental Authority, plus 5% of
the total amount thereof for administration and processing, shall be rendered at
such times as Landlord may elect based upon estimates of Landlord's electric
consultant which may be made from time to time as Landlord deems necessary. In
the event that such bills are not paid within five (5) days after the same are
rendered, Landlord may, without further notice, discontinue the service of
electric current to the demised premises without releasing Tenant from any
liability under this Lease and without Landlord or Landlord's agent incurring
any liability for any damage or loss sustained by Tenant by such discontinuance
of service. Tenant shall permit Landlord's electrical consultant to make surveys
in the demised premises from time to time during normal business hours regarding
the electrical equipment and fixtures and the use of electric current therein.
With respect to the electric current used to run the air conditioning on
Tenant's floor during normal business hours, Landlord shall charge Tenant its
proportionate share of such charge plus sales tax and the administrative fees
referred to above based upon the proportion which the demised premises bears to
the rentable square footage on the entire floor (i.e. 3,997/9,000).

            4.04. Tenant's use of electric current in the demised premises shall
not at any time exceed the capacity


                                       13
<PAGE>

of any of the electrical conductors and equipment in or otherwise serving the
demised premises. Tenant shall not make or perform or permit the making or
performing of, any alterations to wiring, installations or other electrical
facilities in or serving the demised premises without the prior consent of
Landlord in each instance. Should Landlord grant any such consent, all
additional risers or other equipment required therefor shall be installed by
Landlord and the cost thereof shall be paid by Tenant upon Landlord's demand.

            4.05. Landlord shall not be liable in any way to Tenant for any
failure or defect in the supply or character of electric energy furnished to the
demised premises by reason of any requirement, act or omission of the public
utility providing the Building with electricity or for any other reason
whatsoever.

            4.06. If Tenant pays for electric current consumed pursuant to
Section 4.03, Landlord reserves the rights to discontinue furnishing electric
energy to Tenant at any time upon sixty (60) days' written notice to Tenant, and
from and after the effective date of such termination, Landlord shall no longer
be obligated to furnish Tenant with electric energy, provided, however that such
termination date may be extended for a time reasonably necessary for Tenant to
make arrangements to obtain electric service directly from the public utility
company servicing the Building. If Landlord exercises such right of termination,
this Lease shall remain unaffected thereby and shall continue in full force and
effect; and thereafter Tenant shall diligently arrange to obtain electric
service directly from the public utility company servicing the Building, and may
utilize the then existing electric feeders, risers and wiring serving the
demised premises to the extent available and safely capable of being used for
such purpose and only to the extent of Tenant's then authorized connected load.
Landlord shall not be obligated to pay any part of the cost incurred in Tenant
obtaining direct electric service.

            4.07. Tenant covenants and agrees that at no time will the connected
electrical load in the demised premises exceed 4 1/2 watts per square foot.

                                       USE

            5.01. The demised premises shall be used solely as and for executive
and general offices, and for no other purpose.

            5.02. Tenant shall not use or permit the use of the demised premises
or any part thereof in any way which would violate any of the covenants,
agreements, terms, provisions and conditions of this Lease or for any unlawful
purposes or in any unlawful manner or in violation of the Certificate of
Occupancy for the demised premises or the Building, and Tenant shall not permit
the demised premises or any part thereof to be used in any manner or anything to
be done, brought into or kept therein which, in Landlord's judgment shall, or
tend to, impair or interfere with (i) the character, reputation or appearance of
the Building as a high quality office building, (ii) any of the Building
services or the proper and economic heating, cleaning, air conditioning or other
servicing of the Building or the demised premises, or (iii) the use of any of
the other areas of the Building by, or occasional discomfort, inconvenience or
annoyance to, any of the other tenants or occupants of the Building. Tenant
shall not install any electrical or other equipment of any kind which, in the
judgment of Landlord, might cause any such impairment, interference, discomfort,
inconvenience or annoyance or which might overload the risers or feeders
servicing the demised premises or other portions of the Building.

                                    ARTICLE 6

                          ALTERATIONS AND INSTALLATIONS

            6.01. Tenant shall make no alterations, installations, additions or
improvements in or to the demised premises without Landlord's prior written
consent and then only by contractors or mechanics first selected by Tenant and
approved by Landlord; such approval not to be unreasonably withheld or delayed;
provided, however, that with respect to any work affecting the electrical,
plumbing, mechanical or HVAC systems in the Building, Tenant will use only those
contractors designated by Landlord. All such work, alterations, installations,
additions and improvements


                                       15
<PAGE>

shall be done at Tenant's sole expense and at such times and in such manner as
Landlord may from time to time designate.

            Tenant's Extra Work and future work in the demised premises shall be
done solely in accordance with plans and specifications first approved in
writing by Landlord. Tenant shall reimburse Landlord promptly upon demand for
any costs and expenses incurred by Landlord in connection with Landlord's review
of such Tenant's plans and specifications. Landlord will not unreasonably
withhold or delay its consent to requests for nonstructural alterations,
additions and improvements (provided they will not interfere with Landlord's
Work or the operation of the Building nor affect the outside of the Building nor
adversely affect its structure, or its electrical, HVAC, plumbing or mechanical
systems).

            Any such approved alterations and improvements shall be performed in
accordance with the foregoing and the following provisions of this Article 6:

                  1. All work shall be done in a good and workmanlike manner.

                  2. (a) Any contractor employed by Tenant to perform any work
            permitted by this Lease, and all of its subcontractors shall agree
            to employ only such labor as will not result in jurisdictional
            disputes or strikes or cause disharmony with other workers employed
            at the Building. Tenant will inform Landlord in writing of the names
            of any contractor or subcontractors Tenant proposes to use in the
            demised premises at least ten (10) days prior to the beginning of
            work by such contractor or subcontractors.

                        (b) Tenant covenants and agrees to pay to the
            contractor, as the work progresses, the entire cost of supplying the
            materials and performing the work shown on Tenant's approved plans
            and specifications.

                  3. All such alterations shall be performed in compliance with
            all Legal Requirements (as defined in Article 22 hereof) including,
            without limitation, those imposed by the New York City Building
            Department, the New York City Fire Department and O.S.H.A.

                  4. Tenant shall keep the Building and the demised premises
            free and clear of all liens for


                                       16
<PAGE>

            any work or material claimed to have been furnished to Tenant or to
            the demised premises on Tenant's behalf, and all work to be
            performed by Tenant shall be done in a manner which will not
            unreasonably interfere with or disturb other tenants or occupants of
            the Building.

                  5. During the progress of the work to be done by Tenant, said
            work shall be subject to inspection by representatives of Landlord
            who shall be permitted access and the opportunity to inspect, at all
            reasonable times, but this provision shall not in any way whatsoever
            create any obligation on Landlord to conduct such an inspection.

                  6. With respect to alteration or improvement work costing more
            than $25,000 (other than Tenant's Extra Work), Tenant agrees to pay
            to Landlord's managing agent, as additional rent, promptly upon
            being billed therefor, a sum equal to five (5%) percent of the cost
            of such work or alteration, for Landlord's indirect costs, field
            inspection and coordination in connection with such work. However,
            such payment shall not be required of Tenant with respect to Tenant
            Finish Work.

                  7. Prior to commencement of any work, Tenant shall furnish to
            Landlord certificates evidencing the existence of:

                        (a) workmen's compensation insurance covering all
                  persons employed for such work with statutorily required
                  limits; and

                        (b) Employer's liability coverage including bodily
                  injury caused by disease with limits of not less than $100,000
                  per employee;

                        (c) Comprehensive general liability insurance including
                  but not limited to completed operations coverage, products
                  liability coverage, contractural coverage, broad form property
                  damage, independent contractor's coverage and personal injury
                  coverage naming (i) Landlord as well as such representatives
                  and consultants of Landlord as Landlord shall reasonably
                  specify (collectively "Landlord's Consultants"),

                  insureds, with coverage of not less than $3,000,000 combined
                  single limit coverage (or such higher limits as Landlord may
                  from time to time impose in its reasonable judgment);

                        (d) Tenant shall require all contractors engaged or
                  employed by the Tenant to indemnify and hold Tenant, Landlord,
                  and Landlord's Consultants, including but not limited to, as

                  change in the parties constituting Landlord's Consultants):

                  "The contractor hereby agrees to the fullest extent permitted
                  by law to assume the entire responsibility and liability for
                  and defense of and to pay and indemnify the Landlord, Tenant,
                  Jones Lang Wootton, Baro Partners, Exchange Plaza Partners and

                  The contractor's insurance shall specifically insure the
                  foregoing hold harmless provision verbatim.

                  and licensed or authorized to do business in the State of New
                  York, and the policies shall provide that they may not be
                  cancelled without 30 days' prior notice in writing to the
                  Landlord.

                  8. Movement of all men and materials shall only be done at the
            direction, the times and in the manner designated by Landlord.

            6.02. Notice is hereby given that Landlord shall not be liable for
any labor or materials furnished or to be furnished to Tenant upon credit, and
that no mechanic's or other lien for any such labor or materials shall attach to
or affect the reversion or other estate or interest of Landlord in and to the
demised premises. Any mechanic's lien, filed against the demised premises or the
Building for work claimed to have been done for or materials claimed to have
been furnished to Tenant shall be discharged by Tenant at its expense within
fifteen (15) days after notice of such filing, by payment, filing of the bond
required by law or otherwise. Failure to comply with the provisions of this
Section 6.02 shall constitute a material default by Tenant under this Lease
entitling Landlord to exercise any or all of the remedies provided in this Lease
in the event of Tenant's default.

            6.03. All alterations, installations, additions and improvements
made and installed by Landlord, at its expense, including without limitation all
work referred to in Article 2 hereof and in Exhibit C hereto, other than
Tenant's Extra Work, shall be the property of Landlord and shall remain upon and
be surrendered with the demised premises as a part thereof at the end of the
Term.

            6.04. All alterations, installations, additions and improvements
made and installed by Tenant, or at Tenant's expense, upon or in the demised
premises which are


                                         19
<PAGE>

of a permanent nature and which cannot be removed without damage to the demised
premises or Building including, without limitation, Tenant's Extra Work, shall
become the property of Landlord, and shall remain upon and be surrendered with
the demised premises as a part thereof at the end of the Term (and shall not be
removed prior thereto without Landlord's written consent), except that Landlord
shall have the right at any time up to six months prior to the expiration of the
Term to serve notice upon Tenant that any of such alterations, installations,
additions and improvements shall be removed and, in the event of service of such
notice, Tenant will, at Tenant's own cost and expense, remove the same in
accordance with such request, and restore the demised premises to its original
condition, ordinary wear and tear and casualty excepted. Notwithstanding the
foregoing, if upon submitting any plans relating to alterations, installations,
additions and improvements, Tenant shall indicate thereon that, in accordance
with this paragraph 6.04, Landlord must designate in writing such portions of
the alterations, installations, additions and improvements as Landlord may
desire to have Tenant remove at the expiration of the Term as above provided,
then unless Landlord shall, on or before the date that such plans are approved
by Landlord, specify those items which it may desire to have Tenant remove,
Landlord shall have no right to cause Tenant to remove same.

            6.05. Where furnished by or at the expense of Tenant all furniture,
furnishings and trade fixtures, including without limitation, murals, business
machines and equipment, counters, screens, grille work, special panelled doors,
cages, partitions, metal railings, closets, panelling, free standing lighting
fixtures and equipment, drinking fountains, refrigeration and air handling
equipment, and any other moveable property shall remain the property of Tenant
which may at its option remove all or any part thereof at any time prior to the
expiration of the Term. In case Tenant shall decide not to remove any part of
such property, Tenant shall notify Landlord in writing not less than three (3)
months prior to the expiration of the Term, specifying the items of property
which it has decided not to remove. If, within thirty (30) days after the
service of such notice, Landlord shall request Tenant to remove any of the said
property, Tenant shall at its expense remove the same. As to such property which
Landlord does not request Tenant to remove, the same shall be, if left by
Tenant, deemed abandoned by Tenant and thereupon the same shall become the
property of Landlord.

            6.06. If any alterations, installations, additions, improvements or
other property which Tenant shall


                                       20
<PAGE>

have the right to remove or be requested by Landlord to remove as provided in
Sections 6.04 and 6.05 hereof (herein in this Section 6.06 called the
"property") are not removed on or prior to the expiration of the Term, Landlord
shall have the right to remove the property and to dispose of the same without
accountability to Tenant and at the sole cost and expense of Tenant. In case of
any damage to the demised premises or the Building resulting from the removal of
the property Tenant shall repair such damage or, in default thereof, shall
reimburse Landlord for Landlord's cost in repairing such damage. This obligation
shall survive any termination of this Lease.

            6.07. Tenant shall keep records of Tenant's alterations,
installations, additions and improvements costing in excess of $25,000, and of
the cost thereof. Tenant shall, within 45 days after demand by Landlord, furnish
to Landlord copies of such records if Landlord shall require same in connection
with any proceeding to reduce the assessed valuation of the Building, or in
connection with any proceeding instituted pursuant to Article 14 hereof.

                                    ARTICLE 7

                                     REPAIRS

            7.01. Tenant shall, at its sole cost and expense, make such repairs
to the demised premises and the fixtures and appurtenances therein as are
necessitated by the act, omission, occupancy or negligence of Tenant or by the
use of the demised premises in a manner contrary to the purposes for which same
are leased to Tenant, as and when needed to preserve them in good working order
and condition. Except as otherwise provided in Section 9.05 hereof, all damage
or injury to the demised premises and to its fixtures, appurtenances and
equipment caused by Tenant moving property in or out of the Building or by
installation or removal of furniture, fixtures or other property, shall be
repaired, restored or replaced promptly by Tenant at its sole cost and expense,
which repairs, restorations and replacements shall be in quality and class equal
to the original work or installations. If Tenant fails to make such repairs,
restoration or replacements, same may be made by Landlord at the expense of
Tenant and such expense shall be collectible as additional rent and shall be
paid by Tenant within 10 days after rendition of a bill therefor.


                                       21
<PAGE>

            The exterior walls of the Building, the portions of any window sills
outside the windows and the windows are not part of the premises demised by this
Lease and Landlord reserves all rights to such parts of the Building.

            7.02. Tenant shall not place a load upon any floor of the demised
premises exceeding the floor load per square foot area which such floor was
designed to carry and which is allowed by law. The floor of the demised premises
will carry 50 pounds live load per square foot of floor space and 12 pounds for
partitions per square foot of floor space.

            7.03. Business machines and mechanical equipment used by Tenant
which cause vibration, noise, cold or heat that may be transmitted to the
Building structure or to any leased space to such a degree as to be
objectionable to Landlord or to any other tenant in the Building shall be placed
and maintained by Tenant at its expense in settings of cork, rubber or spring
type vibration eliminators sufficient to absorb and prevent such vibration or
noise, or prevent transmission of such cold or heat. The parties hereto
recognize that the operation of elevators, air conditioning and heating
equipment will cause some vibration, noise, heat or cold which may be
transmitted to other parts of the Building and demised premises. Landlord shall
be under no obligation to endeavor to reduce such vibration, noise, heat or cold
beyond what is customary in current good building practice for buildings of the
same type as the Building.

            7.04. Except as otherwise specifically provided in this Lease, there
shall be no allowance to Tenant for a diminution of rental value and no
liability on the part of Landlord by reason of inconvenience, annoyance or
injury to business arising from the making of any repairs, alterations,
additions or improvements in or to any portion of the Building or the demised
premises or in or to fixtures, appurtenances or equipment thereof. Landlord
shall exercise reasonable diligence so as to minimize any interference with
Tenant's business operations, but shall not be required to perform the same on
an overtime or premium pay basis.

                               REQUIREMENTS OF LAW

            8.01. Tenant shall comply with all Legal Requirements which shall
impose any violation, order or duty upon Landlord or Tenant with respect to the
demised premises, or the use or occupation thereof.

            8.02. Notwithstanding the provisions of Section 8.01 hereof, Tenant,
at its own cost and expense, in its name and/or (whenever necessary) Landlord's
name, may contest, in any manner permitted by law (including appeals to a court,
or governmental department or authority having jurisdiction in the matter), the
validity or the enforcement of any Legal Requirements with which Tenant is
required to comply pursuant to this Lease, and may defer compliance therewith
provided that:

                        (a) such non-compliance shall not subject Landlord to
criminal prosecution or subject the Property to lien or sale;

                        (b) such non-compliance shall not be in violation of any
mortgage, or of any ground or underlying lease or any mortgage thereon;

                        (c) Tenant shall first deliver to Landlord a surety bond
issued by a surety company of recognized responsibility, or other security
satisfactory to Landlord, indemnifying and protecting Landlord against any loss
or injury by reason of such non-compliance; and

                        (d) Tenant shall promptly, diligently and continuously
prosecute such contest.

            Landlord, without expense or liability to it, shall cooperate with
Tenant and execute any documents or pleadings required for such purpose,
provided that Landlord shall reasonably be satisfied that the facts set forth in
any such documents or pleadings are accurate.

                                   ARTICLE 9

                    INSURANCE, LOSS, REIMBURSEMENT, LIABILITY

            9.01. Tenant shall not do or permit to be done any act or thing upon
or about the demised premises, which will invalidate or be in conflict with New
York standard fire insurance policies covering the Building, and fixtures and
property therein, or which would increase the rate of fire insurance applicable
to the Building to an amount higher than it otherwise would be; and Tenant shall
neither do nor permit to be done any act or thing upon the demised premises
which shall or might subject Landlord to any liability or responsibility for
injury to any person or persons or to property by reason of any business or
operation being carried on within the demised premises; but nothing in this
Section 9.01 shall prevent Tenant's use of the demised premises for the purposes
stated in Article 5 hereof.

            9.02. If, as a result of any act or omission by Tenant or violation
of this Lease, the rate of fire insurance applicable to the Building shall be
increased to an amount higher than it otherwise would be, Tenant shall reimburse
Landlord for all increases of Landlord's fire insurance premiums so caused; such
reimbursement to be additional rent payable within 5 days after demand therefor
by Landlord. In any action or proceeding wherein Landlord and Tenant are
parties, a schedule or "make-up" of rates for the Building or demised premises
issued by the body making fire insurance rates for the demised premises, shall
be presumptive evidence of the facts stated therein including the items and
charges taken into consideration in fixing the fire insurance rate then
applicable to the demised premises.

            9.03. Landlord or its agents shall not be liable for any injury or
damage to persons or property resulting from fire, explosion, falling plaster,
steam, gas, electricity, water, rain or snow or leaks from any part of the
Building, or from the pipes, appliances or plumbing works or from the roof,
street or subsurface or from any other place or by dampness or by any other
cause of whatsoever nature, unless any of the foregoing shall be caused by or
due to the negligence of Landlord, its agents, servants or employees.

            9.04. Landlord or its agents shall not be liable for any damage
which Tenant may sustain, if at any time any window of the demised premises is
broken, or temporarily or permanently closed, darkened or bricked upon for any
reason


                                       24
<PAGE>

whatsoever, except only Landlord's arbitrary acts if the result is permanent,
and Tenant shall not be entitled to any compensation therefor or abatement of
rent or to any release from any of Tenant's obligations under this Lease, nor
shall the same constitute an eviction or constructive eviction.

            9.05. Tenant shall reimburse Landlord for all expenses, damages or
fines incurred or suffered by Landlord, by reason of any breach, violation or
non-performance by Tenant, or its agents, servants or employees, of any covenant
or provision of this Lease, or by reason of damage to persons or property caused
by moving property of or for Tenant in or out of the Building, or by the
installation or removal of furniture or other property of or for Tenant, or by
reason of or arising out of the carelessness, negligence or improper conduct of
Tenant, or its agents, servants or employees, in the use or occupancy of the
demised premises. Subject to compliance with the provisions of Section 8.02
hereof, where applicable, Tenant shall have the right, at Tenant's own cost and
expense, to participate in the defense of any action or proceeding brought
against Landlord, and in negotiations for settlement thereof if, pursuant to
this Section 9.05, Tenant would be obligated to reimburse Landlord for expenses,
damages or fines incurred or suffered by Landlord.

            9.06. Tenant shall give Landlord notice in case of fire or accidents
in the demised premises promptly after Tenant is aware of such event.

            9.07. Tenant agrees to look solely to Landlord's interest in the
Property, or the lease of the Building or of the Property, and the demised
premises, for the satisfaction of any right or remedy of Tenant for the
collection of a judgment (or other judicial process) requiring the payment of
money by Landlord, in the event of any liability by Landlord, and no other
property or assets of Landlord shall be subject to levy, execution, attachment,
or other enforcement procedure for the satisfaction of Tenant's remedies under
or with respect to this Lease, the relationship of Landlord and Tenant
hereunder, or Tenant's use and occupancy of the demised premises, or any other
liability of Landlord to Tenant.

            9.08. (a) Landlord agrees that it will, at its sole cost and
expense, include in its fire insurance policies appropriate clauses pursuant to
which the insurance companies (i) waive all right of subrogation against Tenant
with respect to losses payable under such policies and (ii) agree that such
policies shall not be invalidated should the insured waive in writing prior to a
loss any or all right of


                                       25
<PAGE>

recovery against any party for losses covered by such policies.

                        (b) Notwithstanding anything to the contrary contained
in this Lease, Tenant agrees that it will, at its sole cost and expense, include
in its property insurance policies appropriate clauses pursuant to which the
insurance companies (i) waive all right of subrogation against Landlord and any
tenant of space in the Building with respect to losses payable under such
policies and (ii) agree that such policies shall not be invalidated should the
insured waive in writing prior to a loss any or all right of recovery against
any party for losses covered by such policies. Tenant shall furnish Landlord
upon demand evidence satisfactory to Landlord evidencing the inclusion of said
clauses in Tenant's property insurance policies.

                        (c) Landlord hereby waives any and all right of recovery
which it might otherwise have against Tenant, its servants, agents and
employees, for loss or damage occurring to the Building and the fixtures,
appurtenances and equipment therein, to the extent the same is covered by
Landlord's insurance, notwithstanding that such loss or damage may result from
the negligence or fault of Tenant, its servants, agents or employees. Tenant
hereby waives any and all right of recovery which it might otherwise have
against Landlord, its servants, and employees, and against every other tenant in
the Building who shall have executed a similar waiver as set forth in this
Section 9.08(b) for loss or damage to, Tenant's furniture, furnishings, fixtures
and other property removable by Tenant under the provisions hereof to the extent
that same is covered by Tenant's insurance, notwithstanding that such loss or
damage may result from the negligence or fault of Landlord, its servants, agents
or employees, or such other tenant and the servants, agents or employees
thereof.

            9.09. Tenant covenants and agrees to provide at its expense on or
before the Commencement Date and to keep in force during the Term naming
Landlord and Tenant as insured parties a comprehensive general liability
insurance policy including, without limitation, blanket contractual liability
coverage, broad form property damage, independent contractor's coverage and
personal injury coverage protecting Landlord and Tenant against any liability
whatsoever, occasioned by any occurrence on or about the demised premises or any
appurtenances thereto. Such policy is to be written by good and solvent
insurance companies licensed to do business in the State of New York
satisfactory to Landlord, and shall be in such limits as


                                       26
<PAGE>

Landlord may reasonably require. As of the date of this Lease Landlord
reasonably requires limits of liability thereunder of not less than $3,000,000
per occurrence for bodily or personal injury (including death) and in the amount
of $1,000,000 per occurrence in respect of property damage. Such insurance may
be carried under a blanket policy covering the demised premises and other
locations of Tenant, if any, provided that each such policy shall in all
respects, comply with this Article and shall specify that the portion of the
total coverage of such policy that is allocated to the demised premises is in
the amounts required pursuant to this Section 9.09. Prior to the time such
insurance is first required to be carried by Tenant and thereafter, at least 15
days prior to the effective date of any such policy, Tenant agrees to deliver to
Landlord a duplicate original of the aforesaid policy and a certificate
evidencing such insurance. Said certificate shall contain an endorsement that
such insurance may not be cancelled except upon 30 days' prior notice to
Landlord. Tenant's failure to provide and keep in force the aforementioned
insurance shall be regarded as a material default hereunder entitling Landlord
to exercise any or all of the remedies provided in this Lease in the event of
Tenant's default. Notwithstanding anything to the contrary contained in this
Lease, the carrying of insurance by Tenant in compliance with this Section shall
not modify, reduce, limit or impair Tenant's obligations and liability under
Article 38 hereof.

                                   ARTICLE 10

                          DAMAGE BY FIRE OR OTHER CAUSE

            10.01. If the Building or the demised premises shall be partially or
totally damaged or destroyed by fire or other cause (and if this Lease shall not
have been terminated as in this Article 10 hereinafter provided), Landlord shall
repair the damage and restore and rebuild the Building and/or the demised
premises, at its expense with reasonable dispatch after notice to it of the
damage or destruction.

            10.02. If the Building or the demised premises shall be damaged or
destroyed by fire or other cause, then unless such fire or damage shall have
resulted from the negligence of Tenant or its officers, contractors, licensees,
agents, employees, guests, invitees or visitors, the rents payable hereunder
shall be abated to the extent that the demised premises shall have been rendered


                                       27
<PAGE>

untenantable for the period from the date of such damage or destruction to the
date the damage shall be repaired or restored; provided, however, that should
Tenant reoccupy a portion of the demised premises during the period the
restoration work is taking place and prior to the date that the whole of said
demised premises are made tenantable, fixed annual rent and additional rents
allocable to such portion shall be payable by Tenant from the date of such
occupancy.

            10.03. If the Building shall be so damaged or destroyed by fire or
other cause (whether or not the demised premises are damaged or destroyed) as to
require a reasonably estimated expenditure made by Landlord or a reputable
contractor designated by Landlord of more than 30% of the full insurable value
of the Building immediately prior to the casualty, then Landlord may terminate
this Lease by giving Tenant notice to such effect within 120 days after the date
of the casualty. In case of any damage or destruction mentioned in this Article
10 which Landlord is required to repair and restore, Tenant may terminate this
Lease by notice to Landlord if Landlord has not completed the making of the
required repairs and restorations within 12 months after the date of such damage
or destruction, or within such period after such date (not exceeding 6 months)
as shall equal the aggregate period Landlord may have been delayed in doing so
by Force Majeure Causes (as defined in Article 34 hereof).

            10.04. No damages, compensation or claim shall be payable by
Landlord for inconvenience, loss of business or annoyance arising from any
repair or restoration of any portion of the demised premises or of the Building
pursuant to this Article 10.

            10.05. Notwithstanding any of the foregoing provisions of this
Article 10, if Landlord or the lessor of any superior lease or the holder of any
superior mortgage shall be unable to collect all of the insurance proceeds
(including rent insurance proceeds) applicable to damage or destruction of the
demised premises or the Building by fire or other cause, by reason of some
action or inaction on the part of Tenant or any of its employees, agents or
contractors, then, without prejudice to any other remedies which may be
available against Tenant, there shall be no abatement of Tenant's rents, but the
total amount of such rents not abated (which would otherwise have been abated)
shall not exceed the amount of uncollected insurance proceeds.


                                       28
<PAGE>

            10.06. Landlord will not carry separate insurance of any kind on
Tenant's property (including, without limitation, any property of the Tenant
which shall become the property of Landlord as provided in Article 6 hereof),
and, except as provided by law, Landlord shall not be obligated to repair any
damage thereto or replace or clean the same, or any other decorations,
installations, equipment or fixtures installed by or for Tenant at Tenant's
expense. Tenant shall maintain such fire and casualty insurance as it deems
advisable.

            10.07. The provisions of this Article 10 shall be considered an
express agreement governing any case of damage or destruction of the demised
premises by fire or other casualty, and Section 227 of the Real Property Law of
the State of New York, providing for such a contingency in the absence of an
express agreement, and any other law of like import, now or hereafter in force,
shall have no application in such case.

                                   ARTICLE 11

                    ASSIGNMENT, MORTGAGING, SUBLETTING, ETC.

            11.01. Except as otherwise expressly provided in this Article 11,
Tenant shall not without, in each instance, obtaining the prior consent of
Landlord, (a) assign or otherwise transfer this Lease or the term and estate
hereby granted, (b) sublet all or part of the demised premises or allow the same
to be used or occupied by others or in violation of Article 5, (c) mortgage,
pledge or encumber this Lease or all or part of the demised premises in any
manner by reason of any act or omission on the part of Tenant, or (d) advertise,
or authorize a broker to advertise, for a subtenant for all or part of the
demised premises or for an assignee of this Lease. For purposes of this Article
11, (i) the transfer of a majority of the issued and outstanding capital stock
of any corporate tenant or subtenant, or the transfer of a majority of the total
interest in any other entity (partnership or otherwise) which is a tenant or
subtenant, however accomplished, whether in a single transaction or in a series
of related or unrelated transactions, shall be deemed an assignment of this
Lease, or of such sublease, as the case may be, (ii) a takeover agreement shall
be deemed a transfer of this Lease, (iii) any person or legal representative of
Tenant, to whom Tenant's interest under this Lease passes by operation of law,
or otherwise, shall be bound by the provisions of this


                                       29
<PAGE>

Article 11, and (iv) a modification, amendment or extension without Landlord's
prior written consent of a sublease previously consented to by Landlord shall be
deemed a new sublease. Tenant agrees to furnish to Landlord upon demand at any
time and from time to time such information and assurances as Landlord may
reasonably request that neither Tenant, nor any subtenant, shall have violated
the provisions of this Section 11.01.

            11.02. The provisions of clauses (a) and (b) of Section 11.01 hereof
shall not apply to transactions entered into by Tenant with a corporation into
or with which Tenant is merged or consolidated or with an entity to which
substantially all of Tenant's assets are transferred, provided (a) such merger,
consolidation or transfer of assets is for a good business purpose and not
principally for the purpose of transferring the leasehold estate created hereby,
and (b) the assignee or successor entity has a net worth at least equal to or in
excess of the net worth of Tenant either (i) immediately prior to such merger,
consolidation or transfer or (ii) as of the date hereof, whichever is greater.

            11.03. Any assignment or transfer, whether made with Landlord's
consent as required by Section 11.01 or without Landlord's consent pursuant to
Section 11.02, shall not be effective unless and until (a) the assignee shall
execute, acknowledge and deliver to Landlord a recordable agreement, in form and
substance reasonably satisfactory to Landlord, whereby the assignee shall (i)
assume the obligations and performance of this Lease and agree to be personally
bound by all of the covenants, agreements, terms, provisions and conditions
hereof on the part of Tenant to be performed or observed on and after the
effective date of any such assignment and (ii) agree that the provisions of this
Article 11 shall, notwithstanding such assignment or transfer, continue to be
binding upon it in the future, and (b) in the case of an assignment or transfer
pursuant to Section 11.02 Tenant or its successor shall have delivered to
Landlord financial statements certified by a reputable firm of certified public
accountants evidencing satisfaction of the net worth requirements referred to in
Section 11.02. Tenant covenants that, notwithstanding any assignment or
transfer, whether or not in violation of the provisions of this Lease, and
notwithstanding the acceptance of fixed annual rent by Landlord from an assignee
or transferee or any other party, Tenant shall remain fully and primarily and
jointly and severally liable for the payment of the fixed annual rent and all
additional rent due and to become due under this Lease and for the performance
and observance of all of the covenants, agreements, terms, provisions and


                                       30
<PAGE>

conditions of this Lease on the part of Tenant to be performed or observed.

            11.04. The liability of Tenant, and the due performance by Tenant of
the obligations on its part to be performed under this Lease, shall not be
discharged, released or impaired in any respect by an agreement or stipulation
made by Landlord or any grantee or assignee of Landlord, by way of mortgage, or
otherwise, extending the time of, or modifying any of the obligations contained
in this Lease, or by any waiver or failure of Landlord to enforce any of the
obligations on Tenant's part to be performed under this Lease, and Tenant shall
continue liable hereunder. If any such agreement or modification operates to
increase the obligations of a tenant under this Lease, the liability under this
Section 11.04 of the tenant named in the Lease or any of its successors in
interest (unless such party shall have expressly consented in writing to such
agreement or modification) shall continue to be no greater than if such
agreement or modification had not been made.

            11.05. Landlord shall not unreasonably withhold or delay its consent
to an assignment of this Lease or a subletting of the whole or a part of the
demised premises for substantially the remainder of the term of this Lease,
provided:

                        (a) Tenant shall furnish Landlord with the name and
business address of the proposed subtenant or assignee, information with respect
to the nature and character of the proposed subtenant's or assignee's business,

Landlord, and an executed counterpart of the Letter of Intent (as defined in
Section 11.06 below);

                        (b) The proposed subtenant or assignee is a reputable
party whose financial net worth, credit and financial responsibility is,
considering the responsibilities involved, reasonably satisfactory to Landlord;

                        (c) The nature and character of the proposed subtenant
or assignee, its business or activities and intended use of the demised premises
are, in Landlord's reasonable judgment, in keeping with the standards of the
Building and the floor or floors on which the demised premises are located;


                                       31
<PAGE>

                        (d) The proposed subtenant or assignee is not then an
occupant of any part of the Building or a party who dealt with Landlord or
Landlord's agent (directly or through a broker) with respect to space in the
Building during the 12 months immediately preceding Tenant's request for
Landlord's consent;

                        (e) All costs incurred with respect to providing
reasonably appropriate means of ingress and egress from the sublet space or to
separate the sublet space from the remainder of the demised premises shall,
subject to the provisions of Article 6 with respect to alterations,
installations, additions or improvements, be borne by Tenant;

                        (f) Each assignment or sublease shall specifically state
that (i) it is subject to all of the terms, covenants, agreements, provisions,
and conditions of this Lease, (ii) the subtenant or assignee, as the case may
be, will not have the right to further assign or sublet all or part of the
demised premises or to allow same to be used by others, without the consent of
Landlord in each instance, (iii) a consent by Landlord thereto shall not be
deemed or construed to modify, amend or affect the terms and provisions of this
Lease, or Tenant's obligations hereunder, which shall continue to apply to the
premises involved, and the occupants thereof, as if the sublease or assignment
had not been made, (iv) if Tenant defaults in the payment of any rent, Landlord
is authorized to collect any rents due or accruing from any assignee, subtenant
or other occupant of the demised premises and to apply the net amounts collected
to the fixed annual rent and additional rent due hereunder, (v) the receipt by
Landlord of any amounts from an assignee or subtenant, or other occupant of any
part of the demised premises shall not be deemed or construed as releasing
Tenant from Tenant's obligations hereunder or the acceptance of that party as a
direct tenant, and (vi) the subtenant shall be required to pay its proportionate
share of Tenant's Tax Payment and Tenant's Expense Payment;

                        (g) Tenant shall together with requesting Landlord's
consent hereunder, have paid Landlord any costs incurred by Landlord to review
the requested consent including any attorney's fees incurred by Landlord;

                        (h) The proposed subtenant or assignee is not (i) a bank
or trust company, safe deposit business, savings and loan association or loan

said Section 11.06 and Landlord shall not have made any of the elections
provided for therein.

            11.06. (a) Should Tenant be willing to agree to assign this Lease or
to sublet all or any portion of the demised premises (other than by an
assignment or sublease permitted by Section 11.02 hereof), Tenant shall, deliver

consent to such proposed assignment or sublease in accordance with the terms of
this Lease or (y) to elect to:

                  A. With respect to a proposed assignment of this Lease,
                  terminate this Lease by giving written notice of such
                  termination to Tenant as of the Effective Date (as hereinafter
                  defined) specified in such notice as if it were the Expiration
                  Date set forth herein;

                  B. With respect to a proposed subletting of the entire demised
                  premises, terminate this Lease by giving written notice of
                  such


                                       33
<PAGE>

                  termination to Tenant as of the Effective Date specified in
                  such notice as if it were the Expiration Date set forth
                  herein; and

                  C. With respect to a proposed subletting of less than the
                  entire demised premises, terminate this Lease by giving
                  written notice of such termination to Tenant with respect to
                  such portion of the demised premises as of the Effective Date
                  specified in such notice as if it were the Expiration Date set
                  forth herein in which case Tenant shall promptly execute and
                  deliver to Landlord an appropriate modification of this Lease
                  in form reasonably satisfactory to Landlord.

For purposes hereof, the "Effective Date" shall mean the date set forth in
Landlord's notice of termination as the date upon which such termination shall
become effective, which date shall not be less than sixty (60) days nor more
than one hundred and fifty (150) days after such notice is given. If Landlord
does not exercise its option to terminate this Lease as to all or a portion of
the demised premises as above provided in this Section 11.06, Tenant shall have
the right to negotiate and enter into an assignment or sublease subject to all
of the other terms, provisions and conditions of this Lease (other than
Landlord's termination right under this Section 11.06) for a period of one
hundred and eighty (180) days after the expiration of said 30-day period on the
terms and conditions set forth in the Letter of Intent. If no such assignment or
sublease is executed and exchanged within such 180-day period, or if the terms
and conditions set forth in the Letter of Intent are changed in any material
respect, Tenant must once again comply with the provisions of Section 11.06 with
respect to such proposed assignment or subletting.

                        (b) If pursuant to the exercise of any of Landlord's
options under this Section 11.06, this Lease is terminated as to only a portion
of the demised premises, then the fixed annual rent payable hereunder and the
additional rent payable pursuant to Article 3 hereof shall be adjusted in
proportion to the portion of the demised premises affected by such termination.

                        (c) If the Landlord shall give its consent to any
assignment of this Lease or to any sublease, Tenant shall in consideration
therefor, pay to Landlord, as additional rent 50% of the following amounts:


                                       34
<PAGE>

                        (i) in the case of an assignment, an amount equal to all
sums and other considerations paid to Tenant by the assignee for or by reason of
such assignment (including, but not limited to, sums paid for the sale of
Tenant's fixtures, leasehold improvements, equipment, furniture, furnishings or
other personal property, less, in the case of a sale thereof, the then net
unamortized or undepreciated cost thereof determined on the basis of Tenant's
federal income tax returns); and

                        (ii) in the case of a sublease, any rents, additional
charges or other consideration payable under the sublease to Tenant by the
subtenant which is in excess of the fixed annual rent and additional rent
accruing during the term of the sublease in respect of the subleased space (at
the rate per square foot payable by Tenant hereunder) pursuant to the terms
hereof (including, but not limited to, sums paid for the sale or rental of
Tenant's fixtures, leasehold improvements, equipment, furniture or furnishings
other personal property, less, in the case of the sale thereof, the then net
unamortized or undepreciated cost thereof determined on the basis of Tenant's
federal income tax returns). The sums payable under this Section 11.06(c) shall
be paid to Landlord as and when paid by the assignee or subtenant to Tenant.

                        (d) If Landlord exercises any of its options under this
Section 11.06, Landlord shall be free to, and shall have no liability to Tenant
if Landlord shall, lease the demised premises or any portion thereof with
respect to which one of such options exercised, to Tenant's proposed assignee or
subtenant, as the case may be.

                            CERTIFICATE OF OCCUPANCY

            12.01. Landlord represents that the Certificate of Occupancy for the
Building will permit the use of the demised premises for the purposes specified
in this Lease. Landlord will make no changes in the Building which would result
in a change in the Certificate of Occupancy so as to prevent Tenant from using
the demised premises for the purposes specified in this Lease.

                          ADJACENT EXCAVATION - SHORING

            13.01. If an excavation or other substructure work shall be made
upon land adjacent to the demised premises, or shall be authorized to be made,
Tenant shall afford to the person causing or authorized to cause such
excavation, license to enter upon the demised premises for the purpose of doing
such work as shall be necessary to preserve the wall of or the Building of which
the demised premises form a part from injury or damage and to support the same
by proper foundations without any claim for damages or indemnity against
Landlord, or diminution or abatement of rent.

                                   ARTICLE 14

                                  CONDEMNATION

            14.01. In the event that the whole of the demised premises shall be
lawfully condemned or taken in any manner for any public or quasi-public use,
this Lease and the term and estate hereby granted shall forthwith cease and
terminate as of the date of vesting of title. In the event that only a part of
the demised premises shall be so condemned or taken, then, effective as of the
date of vesting of title, the fixed annual rent under Article 1 hereof and
additional rents under Article 3 hereof shall be abated proportionately
according to the reduction in the rentable area of the demised premises
resulting from such condemnation or taking. In the event that only a part of the
Building shall be so condemned or taken, then (a) Landlord (whether or not the
demised premises be affected) may, at Landlord's option, terminate this Lease
and the term and estate hereby granted as of the date of such vesting of title
by notifying Tenant in writing of such termination within 60 days following the
date on which Landlord shall have received notice of vesting of title, or (b) if
such condemnation or taking shall be of a substantial part of the demised
premises (25% or more) or of a substantial part of the means of access thereto,
Tenant may, at Tenant's option, by delivery of notice in writing to Landlord
within 30 days following the date on which Tenant shall have received notice of
vesting of title, terminate this Lease and the term and estate hereby granted as
of the date of vesting of title, or (c) if neither Landlord nor Tenant elects to


                                       36
<PAGE>

terminate this Lease, as aforesaid, this Lease shall be and remain unaffected by
such condemnation or taking, except that the fixed annual rent payable under
Article 1 and additional rents payable under Article 3 shall be abated to the
extent hereinbefore provided in this Article 14.

            14.02. In the event of termination of this Lease in any of the cases
hereinbefore provided, this Lease and the term and estate hereby granted shall
expire as of the date of such termination with the same effect as if that were
the Expiration Date, and the fixed annual rent and additional rents payable
hereunder shall be apportioned as of such date.

            14.03. In the event of any condemnation or taking of all or a part
of the Building, Landlord shall be entitled to receive the entire award in the
condemnation proceeding, including any award made for the value of the estate
vested by this Lease in Tenant. Tenant hereby expressly assigns to Landlord any
and all right, title and interest of Tenant now or hereafter arising in or to
any such award or any part thereof, and agrees that it shall not be entitled to
receive any part of such award.

            14.04. In the event of any taking of less than the whole of the
Building which does not result in a termination of this Lease, Landlord, at its
expense, shall proceed with reasonable diligence to repair, alter and restore
the remaining parts of the Building and the demised premises to substantially
their former condition to the extent that the same may be feasible and so as to
constitute a complete and tenantable Building and demised premises.

            14.05. In the event any part of the demised premises be taken to
effect compliance with any law or requirement of public authority other than in
the manner hereinabove provided in this Article 14, then, (i) if such compliance
is the obligation of Tenant under this Lease, Tenant shall not be entitled to
any diminution or abatement of rent or other compensation from Landlord
therefor, but (ii) if such compliance is the obligation of Landlord under this
Lease, the fixed annual rent hereunder shall be reduced and additional rents
under Article 3 shall be adjusted in the same manner as is provided in Section
14.01 according to the reduction in rentable area of the demised premises
resulting from such taking.

                       ACCESS TO DEMISED PREMISES; CHANGES

            15.01. Tenant shall permit Landlord to erect, use and maintain
pipes, ducts and conduits in and through the demised premises, provided the same
are installed adjacent to or concealed behind walls and ceilings of the demised
premises. Landlord shall to the extent practicable install such pipes, ducts and
conduits by such methods and at such locations as will not materially interfere
with or impair Tenant's layout or use of the demised premises. Landlord or its
agents or designees shall have the right, but only upon notice to Tenant or any
authorized employee of Tenant at the demised premises, to enter the demised
premises, during business hours, (a) for the making of such repairs or
alterations as Landlord may deem necessary for the Building or which Landlord
shall be required to or shall have the right to make by the provisions of this
Lease or any other lease in the Building and (b) for the purpose of inspecting
them or exhibiting them to existing or prospective purchasers, mortgagees or
lessees of all or part of the Land, Building or Property or to prospective
assignees, agents or designees of any such parties. Landlord shall be allowed to
take all material into and upon the demised premises that may be required for
the repairs or alterations above mentioned without the same constituting an
actual or constructive eviction of Tenant in whole or in part, and the rent
reserved hereunder shall not abate while said repairs or alterations are being
made by reason of loss or interruption of the business of Tenant because of the
prosecution of any such work. Landlord shall exercise reasonable diligence so as
to minimize the disturbance to Tenant but nothing contained herein shall be
deemed to require Landlord to perform the same on an overtime or premium pay
basis.

            15.02. Landlord reserves the right, without the same constituting an
actual or constructive eviction and without incurring liability to Tenant
therefor, to change the arrangement and/or location of public entrances,
passageways, doors, doorways, corridors, elevators, stairways, toilets and other
public parts of the Building; provided, however, that access to the Building
shall not be cut off and that there shall be no unreasonable obstruction of
access to the demised premises or unreasonable interference with the use or
enjoyment thereof.

<PAGE>

            15.03. Landlord reserves the right to light from time to time all or
any portion of the demised premises at night for display purposes without paying
Tenant therefor.

            15.04. Landlord may, during the twelve (12) months prior to
expiration of the Term exhibit the demised premises to prospective tenants.

            15.05. If Tenant shall not be personally present to open and permit
an entry into the demised premises at any time when for any reason an entry
therein shall be urgently necessary by reason of fire or emergency, Landlord or
Landlord's agents may forceably enter the same without rendering Landlord or
such agents liable therefor (if during such entry Landlord or Landlord's agents
shall accord reasonable care to Tenant's property) and without in any manner
affecting the obligations and covenants of this Lease.

                                   ARTICLE 16

                            CONDITIONS OF LIMITATION

            16.01. This Lease and the term and estate hereby granted are subject
to the limitation that whenever Tenant shall make an assignment of the property
of Tenant for the benefit of creditors, or if a petition shall be filed by or
against Tenant under any provisions of the United States Bankruptcy Act or under
the provisions of any other bankruptcy or insolvency law or any law of like
import, or whenever a permanent receiver of Tenant or of or for the property of
Tenant shall be appointed, then, Landlord may, (a) at any time after receipt of
notice of the occurrence of any such event, or (b) if such event occurs without
the acquiescence of Tenant, at any time after the event continues for thirty
(30) days, give Tenant a notice of intention to end the Term of this Lease at
the expiration of 5 days from the date of service of such notice of intention,
and upon the expiration of said 5 day period this Lease and the Term and estate
hereby granted, whether or not the Term shall theretofore have commenced, shall
terminate with the same effect as if that day were the Expiration Date, but
Tenant shall remain liable for damages as provided in Article 18.

            16.02. This Lease and the Term and estate hereby granted are subject
to further limitation as follows:


                                       39
<PAGE>

                        (a) whenever Tenant shall fail to pay any installment of
fixed annual rent or any additional rent or any other charge payable by Tenant
to Landlord, on the day the same is due and payable pursuant to the terms
hereof, and such default shall continue for 5 days after Landlord shall have
given Tenant a notice specifying such default, or

                        (b) whenever Tenant shall do or permit anything to be
done, whether by action or inaction, contrary to any of Tenant's obligations
hereunder, and if such situation shall continue and shall not be remedied by
Tenant within 15 days after Landlord shall have given to Tenant a notice
specifying the same, or, in the case of a happening or default which cannot with
due diligence be cured within a period of 15 days and the continuation of the
period required for cure will not subject Landlord to the risk of criminal
liability (as more particularly described in Article 8 hereof) or termination of
any superior lease or foreclosure of any superior mortgage, if Tenant shall not,
(i) within said 15 day period advise Landlord of Tenant's intention to duly
institute all steps necessary to remedy such situation, (ii) duly institute
within said 15 day period, and thereafter diligently and continuously prosecute
to completion all steps necessary to remedy the same and (iii) complete such
remedy within such time after the date of the giving of said notice of Landlord
as shall reasonably be necessary, or

                        (c) whenever any event shall occur or any contingency
shall arise whereby this Lease or the estate hereby granted or the unexpired
balance of the Term hereof would, by operation of law or otherwise, devolve upon
or pass to any person, firm or corporation other than Tenant, except as
expressly permitted by Article 11, or

                        (d) whenever Tenant shall abandon the demised premises
(unless as a result of a casualty), or

                        (e) whenever in case any other lease held by Tenant from
Landlord shall expire and terminate (whether or not the term thereof shall then
have commenced) as a result of the default of Tenant thereunder, or

                        (f) whenever Tenant shall fail to do, observe or perform
any act or thing to be done, observed or performed by Tenant pursuant to the
Work Agreement annexed hereto as Schedule C, or

                        (g) whenever Tenant shall default in the due keeping,
observing or performance of any covenant, agreement, provision or condition of
Article 5 hereof on the


                                       40
<PAGE>

part of Tenant to be kept, observed or performed and if such default shall
continue and shall not be remedied by Tenant within 24 hours after Landlord
shall have given to Tenant a notice specifying the same,

then in any of said cases set forth in the foregoing Subsections (a), (b), (c),
(d), (e), (f) and (g) Landlord may give to Tenant a notice of intention to end
the Term at the expiration of 3 days from the date of the service of such notice
of intention, and upon the expiration of said 3 days this Lease and the Term and
estate hereby granted, whether or not the Term shall theretofore have commenced,
shall terminate with the same effect as if that day were the Expiration Date,
but Tenant shall remain liable for damages as provided in Article 18.

                                   ARTICLE 17

                        RE-ENTRY BY LANDLORD, INJUNCTION

            17.01. If Tenant shall fail to pay any installment of fixed annual
rent, or of any additional rent, or any other charge payable by Tenant to
Landlord on the date the same is due and payable, and if such default shall
continue for 5 days after Landlord shall have given to Tenant a notice
specifying such default, or if this Lease shall terminate as in Article 16
provided, Landlord or Landlord's agents and employees may immediately or at any
time thereafter re-enter the demised premises, or any part thereof, either by
summary dispossess proceedings or by any suitable action or proceeding at law,
or by force or otherwise, without being liable to indictment, prosecution or
damages therefrom. The word re-enter, as herein used, is not restricted to its
technical legal meaning.

            17.02. In the event of a breach or threatened breach by Tenant of
any of its obligations under this Lease, Landlord shall also have the right of
injunction. The special remedies to which Landlord may resort hereunder are
cumulative and are not intended to be exclusive of any other remedies or means
of redress to which Landlord may lawfully be entitled at any time and Landlord
may invoke any remedy allowed at law or in equity as if specific remedies were
not provided for herein.

            17.03. If this Lease shall terminate under the provisions of Article
16, or if Landlord shall re-enter the demised premises under the provisions of
this Article 17, or


                                       41
<PAGE>

in the event of the termination of this Lease, or of re-entry by or under any
summary dispossess or other proceeding or action or any provision of law by
reason of default hereunder on the part of Tenant, then (a) Tenant shall
thereupon pay to Landlord the fixed annual rent and additional rent payable by
Tenant to Landlord up to the time of such termination of this Lease, or of such
recovery of possession of the demised premises by Landlord, as the case may be,
and shall also pay to Landlord damages as provided in Article 18, and (b)
Landlord shall be entitled to retain all moneys, if any, paid by Tenant to
Landlord, whether as advance rent, security or otherwise, but such moneys shall
be credited by Landlord against any fixed annual rent or additional rent due
from Tenant at the time of such termination or re-entry or, at Landlord's option
against any damages payable by Tenant under Articles 16 and 18 or pursuant to
law.

            17.04. Tenant hereby expressly waives any and all rights of
redemption granted by or under any present or future laws in the event of Tenant
being evicted or dispossessed for any cause, or in the event of Landlord
obtaining possession of the demised premises, by reason of the violation by
Tenant of any of the covenants and conditions of this Lease or otherwise.

                                   ARTICLE 18

                                     DAMAGES

            18.01. If this Lease is terminated under the provisions of Article
16, or if Landlord shall re-enter the demised premises under the provisions of
Article 17, or in the event of the termination of this lease, or of re-entry by
or under any summary dispossess or other proceeding or action or any provision
of law by reason of default hereunder on the part of Tenant, Tenant shall pay to
Landlord as damages, at the election of Landlord, either

                        (a) a sum which at the time of such termination of this
Lease or at the time of any such re-entry by Landlord, as the case may be,
represents the then value of the excess, if any, of

                  (1) the aggregate of the fixed annual rent and the additional
            rent payable hereunder which would have been payable by Tenant
            (conclusively presuming the additional rent to be the same as


                                       42
<PAGE>

            was payable for the year immediately preceding such termination
            except that additional rent on account of increases in Real Estate
            Taxes and Expenses shall be presumed to increase at the average of
            the rates of increase thereof previously experienced by Landlord
            during the period (not to exceed 3 years) prior to such termination)
            for the period commencing with such earlier termination of this
            Lease or the date of any such re-entry, as the case may be, and
            ending with the Expiration Date, had this Lease not so terminated or
            had Landlord not so re-entered the demised premises, over

                  (2) the aggregate rental value of the demised premises for the
            same period, or

                        (b) sums equal to the fixed annual rent and the
additional rent payable hereunder which would have been payable by Tenant had
this Lease not so terminated, or had Landlord not so re-entered the demised
premises, payable upon the due dates therefor specified herein following such
termination or such re-entry and until the Expiration Date, provided, however,
that if Landlord shall re-let the demised premises during said period, Landlord
shall credit Tenant with the net rents received by Landlord from such
re-letting, such net rents to be determined by first deducting from the gross
rents as and when received by Landlord from such re-letting, the expenses
incurred or paid by Landlord in terminating this Lease or in re-entering the
demised premises and in securing possession thereof, as well as the expenses of
re-letting, including altering and preparing the demised premises for new
tenants, brokers' commissions, legal fees, and all other expenses properly
chargeable against the demised premises and the rental thereof; it being
understood that any such re-letting may be for a period shorter or longer than
the remaining term of this Lease. In no event shall Tenant be entitled to
receive any excess of such net rents over the sums payable by Tenant to Landlord
hereunder for the period of such re-letting, or shall Tenant be entitled in any
suit for the collection of damages pursuant to this subsection to a credit in
respect of any net rents from a re-letting, except to the extent that such net
rents are actually received by Landlord. If the demised premises or any part
thereof should be re-let in combination with other space, then proper
apportionment on a square foot basis shall be made of the rent received from
such re-letting and of the expenses of re-letting. If the demised premises or
any part thereof be re-let by Landlord for the unexpired portion of the term of
this Lease, or any part thereof, before presentation of proof of such damages


                                       43
<PAGE>

to any court, commission or tribunal, the amount of rent payable pursuant to
such re-letting shall, prima facie, be the fair and reasonable rental value for
the demised premises, or part thereof, so re-let during the term of the
re-letting.

            18.02. Suit or suits for the recovery of such damages, or any
installments thereof, may be brought by Landlord from time to time at its
election, and nothing contained herein shall be deemed to require Landlord to
postpone suit until the date when the Term would have expired if it had not been
so terminated under the provisions of Article 16, or under any provision of law,
or had Landlord not re-entered the demised premises. Nothing herein contained
shall be construed to limit or preclude recovery by Landlord against Tenant of
any sums or damages to which, in addition to the damages particularly provided
above, Landlord may lawfully be entitled by reason of any default hereunder on
the part of Tenant. Nothing herein contained shall be construed to limit or
prejudice the right of Landlord to prove for and obtain as liquidated damages by
reason of the termination of this Lease or re-entry of the demised premises for
the default of Tenant under this Lease, an amount equal to the maximum allowed
by any statute or rule of law in effect at the time when, and governing the
proceedings in which, such damages are to be proved whether or not such amount
be greater, equal to, or less than any of the sums referred to in Section 18.01.

                                   ARTICLE 19

                LANDLORD'S RIGHT TO PERFORM TENANT'S OBLIGATIONS

            19.01. If Tenant shall default in the observance or performance of
any term or covenant on Tenant's part to be observed or performed under any of
the terms or provisions of this Lease, (a) Landlord may remedy such default for
the account of Tenant, immediately and without notice in case of emergency, or
in any other case if Tenant shall fail to remedy such default with all
reasonable dispatch after Landlord shall have notified Tenant in writing of such
default and the applicable grace period for curing such default shall have
expired; and (b) if Landlord makes any expenditures or incurs any obligations
for the payment of money in connection with such default including, but not
limited to, reasonable attorneys' fees in instituting, prosecuting or defending
any action or proceeding, such sums paid or obligations incurred, with


                                       44
<PAGE>

interest at the Interest Rate, shall be deemed to be additional rent hereunder
and shall be paid by Tenant to Landlord upon rendition of a bill to Tenant
therefor. The provisions of this Article 19 shall survive the expiration or
other termination of this Lease.

                                   ARTICLE 20

                                 QUIET ENJOYMENT

            20.01. Landlord covenants and agrees that subject to the terms and
provisions of this Lease, if, and so long as, Tenant keeps and performs each and
every covenant, agreement, term, provision and condition herein contained on the
part or on behalf of Tenant to be kept or performed, then Tenant's rights under
this Lease shall not be cut off or ended before the expiration of the term of
this Lease, subject however, to: (i) the obligations of this Lease, and (ii) the
provisions of Article 25 hereof with respect to Superior Instruments which
affect this Lease.

                                   ARTICLE 21

                             SERVICES AND EQUIPMENT

            21.01. So long as Tenant is not in default under any of the
covenants of this Lease, Landlord shall:

                        (a) Provide necessary elevator facilities on business
days from 8:00 A.M. to 6:00 P.M. and shall have at least one elevator subject to
call at all other times. At Landlord's option, the elevators shall be operated
by automatic control or by manual control, or by a combination of both of such
methods.

                        (b) Maintain and keep in good order and repair the air
conditioning, heating and ventilating systems installed by Landlord. The heating
and ventilation systems will function when seasonably required on business days
from 8:00 A.M. to 6:00 P.M. as more fully described in Schedule C annexed hereto
and made a part hereof. The air conditioning system (as it relates to the
demised premises) shall have separate controls in the demised premises and may
be operated by Tenant as required if the demised premises constitute an entire
floor; with respect to partial floors


                                       45
<PAGE>

said controls shall be operated by the concierge of the Building. Landlord has
informed Tenant that the windows of the demised premises and the Building are
sealed, and that the demised premises may become uninhabitable and the air
therein may become unbreathable during the hours or days when Landlord is not
required pursuant to this paragraph to furnish heat or ventilation or when
Tenant does not operate the air-conditioning systems. Any use or occupancy of
the demised premises during such hours shall be at the sole risk, responsibility
and hazard of Tenant, and Landlord shall have no responsibility or liability
therefor. Such condition of the demised premises shall not constitute nor be
deemed to be a breach or a violation of this Lease or of any provision thereof,
nor shall it be deemed an actual or constructive eviction nor shall Tenant claim
or be entitled to claim any abatement of rent nor make any claim for any damages
or compensation by reason of such condition of the demised premises. Tenant
shall cause and keep entirely unobstructed all the vents, intakes, outlets and
grilles, at all times and shall comply with and observe all regulations and
requirements prescribed by Landlord for the proper functioning of the heating,
ventilating and air-conditioning systems. Nothing contained herein shall be
deemed to require Landlord to furnish at Landlord's expense such electric energy
as is required to operate the air conditioning system serving the demised
premises. Subject to the provisions of Article 4 hereof all such electric energy
shall be furnished to Tenant at Tenant's cost and expense. In the event that
Tenant shall require heating or ventilation (or air conditioning if Tenant
occupies a partial floor) at such times as same are not furnished by Landlord,
Tenant shall advise the concierge of the Building of such requirement and, the
same shall be furnished by Landlord. Tenant agrees to pay the Landlord's charges
therefor as additional rent. The temperature controls for the air conditioning
shall be in the demised premises as provided for in Schedule C but the controls
for turning on said air conditioning shall be with the concierge.

                        (c) Provide the cleaning and janitorial services
described on Schedule F annexed hereto on business days.

                        (d) Furnish water for lavatory and drinking and office
cleaning purposes. If Tenant requires, uses or consumes water for any other
purposes, Tenant agrees that Landlord may install a meter or meters or other
means to measure Tenant's water consumption, and Tenant further agrees to
reimburse Landlord for the cost of the meter or meters and the installation
thereof, and to pay for the


                                       46
<PAGE>

maintenance of said meter equipment and/or to pay Landlord's cost of other means
of measuring such water consumption by Tenant. Tenant shall reimburse Landlord
for the cost of all water consumed, as measured by said meter or meters or as
otherwise measured, including sewer rents.

            21.02. Landlord reserves the right without any liability whatsoever,
or abatement of fixed annual rent, or additional rent, to stop the heating, air
conditioning, elevator, plumbing, electric and other systems when necessary by
reason of accident or emergency or for repairs, alterations, replacements or
improvements, provided that except in case of emergency, Landlord will notify
Tenant in advance, if possible, of any such stoppage and, if ascertainable, its
estimated duration, and will proceed diligently with the work necessary to
resume such service as promptly as possible and in a manner so as to minimize
interference with the Tenant's use and enjoyment of the demised premises, but
Landlord shall not be obligated to employ overtime or premium labor therefor.

            21.03. Tenant shall reimburse Landlord for the cost to Landlord of
removal from the demised premises and the Building of so much of any refuse and
rubbish of Tenant as shall exceed that ordinarily accumulated daily in the
routine of general business office occupancy.

            21.04. It is expressly agreed that any firm or corporation
furnishing laundry, linen towels, drinking water, ice, food or beverages, cable
television and other similar supplies and services to tenants and licensees in
the Building is subject to being excluded from the Building if Landlord, in its
reasonable judgment, determines that such firm or corporation interferes with
the operation of the Building. Landlord may fix, in its own absolute discretion,
at any time and from time to time, the hours during which and the regulations
under which such supplies and services are to be furnished. It is understood,
however, that Tenant or regular office employees of Tenant who are not employed
by any supplier of such food or beverages or by any person, firm or corporation
engaged in the business of purveying such food or beverages, may personally
bring food or beverages into the Building for consumption within the demised
premises by employees of Tenant, but not for resale to or for consumption by any
other tenant. Landlord may fix in its absolute discretion, at any time and from
time to time, the hours during which, and the regulations under which, foods and
beverages may be brought into the Building by regular employees of Tenant.

            21.05. Tenant agrees to employ such office maintenance contractor as
Landlord may from time to time designate, for all waxing, polishing, cleaning
(other than those cleaning services Landlord is obligated to furnish) and
maintenance work in the demised premises, provided that the quality thereof and
the charges therefor are reasonably comparable to that of other contractors.
Tenant shall not employ any other contractor without Landlord's prior written
consent.

            21.06. Landlord will not be required to furnish any other services,
except as otherwise provided in this Lease.

                                   ARTICLE 22

                                   DEFINITIONS

            22.01. The term "Landlord" as used in this Lease means only the

lease, or in the event of a lease of the Building, or of the Land and Building,
upon notification to Tenant of such transfer or lease the said transferor
Landlord shall be and hereby is entirely freed and relieved of all existing or
future covenants, obligations and liabilities of Landlord hereunder, and it

lesser of (a) 2% above the so-called

or if Republic National Bank shall cease to exist or cease to announce such
rate, any similar rate designated by Landlord which is publicly announced from
time to time by any other bank (a "Substitute Bank") in the City of New York
having combined capital and surplus in excess of $100,000,000 or (b) the maximum
rate of interest, if any, which Tenant may legally contract to pay.

            22.04. "Legal Requirements" shall mean laws, statutes and ordinances
including building codes and zoning regulations and ordinances and the orders,

                                   ARTICLE 23

                           INVALIDITY OF ANY PROVISION

            23.01. If any term, covenant, condition or provision of this Lease
or the application thereof to any circumstance or to any person, firm or
corporation shall be invalid or unenforceable to any extent, the remaining
terms, covenants, conditions and provisions of this Lease shall not be affected
thereby and each remaining term, covenant, condition and provision of this Lease
shall be valid and shall be enforceable to the fullest extent permitted by law.

                                   ARTICLE 24

                                    BROKERAGE

            24.01. Tenant covenants, represents and warrants that Tenant has had
no dealings or negotiations with any broker or agent other than Jones Lang
Wootton (which is representing Landlord) and Edward S. Gordon & Company in
connection with the consummation of this Lease, and Tenant covenants and agrees
to pay, hold harmless and indemnify


                                       49
<PAGE>

Landlord from and against any and all cost, expense (including reasonable
attorneys' fees and court costs), loss and liability for any compensation,
commissions or charges claimed by any broker or agent, other than the brokers
set forth in this Section 24.01, with respect to this Lease or the negotiation
thereof if such claim or claims by any such broker or agent are based in whole
or in part on dealing with Tenant or its representatives. Landlord agrees to pay
to the brokers specified in this Section 24.01 such compensation, commissions or
charges to which they are entitled pursuant to the separate agreements between
said brokers and Landlord.

                                   ARTICLE 25

                                  SUBORDINATION

            25.01. This Lease is and shall be subject and subordinate to all
ground or underlying leases which may now or hereafter affect the Land or the
Building and to all mortgages which may now or hereafter affect such leases, the
Land or the Building, and to all renewals, refinancings, modifications,
replacements and extensions thereof (hereinafter called "Superior Instruments").
The provisions of this Section 25.01 shall be self-operative and no further
instrument of subordination shall be required. In confirmation of such
subordination, Tenant shall promptly execute and deliver at its own cost and
expense any instrument, in recordable form if required, that Landlord, the
holder of any Superior Instrument or any of their respective successors in
interest may request to evidence such subordination, and Tenant hereby
constitutes and appoints Landlord or its successors in interest to be Tenant's
attorney-in-fact, irrevocably and coupled with an interest, to execute and
deliver any such instrument for and on behalf Tenant.

            25.02. In the event of a termination of any ground or underlying
lease, or if the interests of Landlord under this Lease are transferred by
reason of, or assigned in lieu of, foreclosure or other proceedings for
enforcement of any mortgage, or if the holder of any mortgage acquires a lease
in substitution therefor, then Tenant under this Lease will, at the option to be
exercised in writing by the holder of any such Superior Instrument or any
purchaser, assignee or lessee, as the case may be, either (i) attorn to it and
will perform for its benefit all the terms, covenants and conditions of this
Lease on Tenant's part to be performed


                                       50
<PAGE>

with the same force and effect as if it were the landlord originally named in
this Lease, or (ii) enter into a new lease with it for the remaining term of
this Lease and otherwise on the same terms and conditions and with the same
options, if any, then remaining. The foregoing provisions of clause (i) of this
Section 25.02 shall enure to the benefit of such holder of a Superior
Instrument, purchaser, assignee or lessee, shall be self-operative upon the
exercise of such option, and no further instrument shall be required to give
effect to such option, and no further instrument shall be required to give
effect to said provisions. Tenant, however, upon demand of any such holder of a
Superior Instrument, purchaser, assignee or lessee agrees to execute, from time
to time, instruments in confirmation of the foregoing provisions of this Section
25.02, satisfactory to any such holder of a Superior Instrument, purchaser,
assignee or lessee, acknowledging such attornment and setting forth the terms
and conditions of its tenancy. Tenant hereby constitutes and appoints Landlord
or its successors in interest to be the Tenant's attorney-in-fact, irrevocably
and coupled with an interest, to execute and deliver such instrument of
attornment, or such new lease, if the Tenant refuses or fails to do so promptly
upon request.

            25.03. Anything herein contained to the contrary notwithstanding,
under no circumstances shall any such holder of a Superior Instrument,
purchaser, assignee or lessee, as the case may be, whether or not it shall have
succeeded to the interests of the landlord under this Lease, be

                  (a) liable for any act, omission or default of any prior
landlord; or

                  (b) subject to any offsets, claims or defenses which the
Tenant might have against any prior landlord; or

                  (c) bound by any rent or additional rent which Tenant might
have paid to any prior landlord for more than one month in advance or for more
than three months in advance where such rent payments are payable at intervals
of more than one month; or

                  (d) bound by any modification, amendment or abridgment of the
Lease, or any cancellation or surrender of the same, made without its prior
written approval.

            25.04. If, in connection with the financing of the Building, the
holder of any mortgage shall request


                                       51
<PAGE>

reasonable modifications in this Lease as a condition of approval thereof,
Tenant will not unreasonably withhold, delay or defer making such modifications
provided the same do not (i) increase the fixed annual rent or additional rents
payable by Tenant, (ii) reduce the term hereof or (iii) extend the term hereof
except as otherwise provided in Section 2.06.

            25.05. If Landlord shall turn over to the holder of a Superior
Instrument the Security Deposit deposited by Tenant with Landlord pursuant to
Article 41 hereof, then notwithstanding anything to the contrary contained
herein, such holder shall hold same subject to and in accordance with all Legal
Requirements.

                                   ARTICLE 26

                              CERTIFICATE OF TENANT

            26.01. Tenant shall, without charge, at any time and from time to
time, within ten (10) days after request by Landlord, execute, acknowledge and
deliver to Landlord, the holder of a Superior Instrument or any other person,
firm or corporation specified by Landlord, a written instrument (an "Estoppel
Certificate") in the form attached hereto as Schedule D or such other form as
may be required by the holder of any Superior Instrument. Prior to taking
occupancy of the demised premises, and as a condition precedent thereto, Tenant
shall execute, acknowledge and deliver such an estoppel certificate to Landlord.

            26.02. Tenant agrees that, except for the first month's rent
hereunder, it will pay no rent under this Lease more than thirty (30) days in
advance of its due date, if so restricted by any existing or future Superior
Instrument or by an assignment of this Lease to the holder of such Superior
Instrument, and, in the event of any act or omission by Landlord which would
give Tenant the right to terminate this Lease, Tenant will not exercise such
right until Tenant shall have first given written notice of such act or omission
to the holder of any Superior Instrument who shall have furnished such holder's
last address to Tenant, and until a reasonable period for remedying such act or
omission shall have elapsed following the giving of such notices, during which
time such holder shall have the right, but shall not be obligated, to remedy or
cause to be remedied such act or omission. Tenant further agrees not to exercise
any such right if the holder of any such Superior


                                       52
<PAGE>

Instrument commences to cure such act or omission within a reasonable time after
having received notice thereof and diligently prosecutes such cure thereafter.

                     LEGAL PROCEEDINGS, WAIVER OF JURY TRIAL

            27.01. Landlord and Tenant hereby waive trial by jury in any action,
proceeding or counterclaim brought by either of the parties hereto against the
other on any matters whatsoever arising out of or in any way in connection with
this Lease, the relationship of Landlord and Tenant, Tenant's use or occupancy
of the demised premises, and/or any other claims (except claims for personal
injury or property damage), and any emergency statutory or any other statutory
remedy. It is further mutually agreed that in the event Landlord commences any
summary proceeding for non-payment of rent, Tenant will not interpose and does
hereby waive the right to interpose any counterclaim of whatever nature or
description in any such proceeding. Tenant shall reimburse Landlord upon demand
for all costs and expenses (including attorney's fees and disbursements and
court costs) incurred by Landlord in connection with enforcing Tenant's
obligations hereunder or in protecting Landlord's rights hereunder whether
incurred in connection with an action or proceeding commenced by Landlord, by
Tenant, by a third party or otherwise. All such amounts shall be deemed to be
additional rent and shall be collectible in the same manner as provided in
Section 1.02 hereof.

                                   ARTICLE 28

                              SURRENDER OF PREMISES

            28.01. Upon the expiration or other termination of the Term, Tenant
shall quit and surrender to Landlord the demised premises, broom clean, in good
order and condition, ordinary wear and tear and damage by fire, the elements or
other casualty excepted, and Tenant shall remove all of its property as herein
provided. Tenant's obligation to observe or perform this covenant shall survive
the expiration or other termination of the Term.


                                       53
<PAGE>

            28.02. If Tenant shall, without the written consent of Landlord,
hold over after the expiration of the Term such tenancy shall be deemed a
month-to-month tenancy, which tenancy may be terminated as provided by
applicable law. During such tenancy, Tenant agrees to (a) pay to Landlord, each
month, the greater of the fair market rental value for the Premises or one
hundred twenty (120) percent of the fixed annual rent and all additional rent
payable by Tenant for the last month of the Term and (b) be bound by all of the
terms, covenants and conditions herein specified.

                                   ARTICLE 29

                              RULES AND REGULATIONS

            29.01. Tenant and Tenant's servants, employees and agents shall
observe faithfully and comply strictly with the Rules and Regulations set forth
in Schedule E attached hereto and made part hereof entitled "Rules and
Regulations" and such other and further reasonable Rules and Regulations as
Landlord or Landlord's agents may from time to time adopt provided, however,
that in case of any conflict or inconsistency between the provisions of this
Lease and of any of the Rules and Regulations as originally or as hereafter
adopted, the provisions of this Lease shall control. Reasonable written notice
of any additional Rules and Regulations shall be given to Tenant.

            Nothing in this Lease contained shall be construed to impose upon
Landlord any duty or obligation to enforce the Rules and Regulations or the
terms, covenants or conditions in any other lease, against any other tenant of
the Building, and Landlord shall not be liable to Tenant for violation of the
same by any other tenant, its servants, employees, agents, visitors or
licensees.

                                   ARTICLE 30

                             CONSENTS AND APPROVALS

            30.01. Wherever in this Lease Landlord's consent or approval is
required, if Landlord shall delay or refuse such consent or approval, Tenant in
no event shall be entitled to make, nor shall Tenant make, any claim, and Tenant
hereby waives any claim, for money damages (nor shall


                                       54
<PAGE>

Tenant claim any money damages by way of set-off, counterclaim or defense) based
upon any claim or assertion by Tenant that Landlord unreasonably withheld or
unreasonably delayed its consent or approval. Tenant's sole remedy shall be an
action or proceeding to enforce any such provision, for specific performance,
injunction or declaratory judgment.

                                   ARTICLE 31

                                     NOTICES

            31.01. Any notice or demand, consent, approval or disapproval, or
statement (collectively called "Notices") required or permitted to be given by
the terms and provisions of this Lease, or by any law or governmental
regulation, either by Landlord to Tenant or by Tenant to Landlord, shall be in
writing and unless otherwise required by such law or regulation, shall be sent
by United States mail postage prepaid as registered or certified mail, return
receipt requested. Any Notice shall be addressed to Landlord or Tenant, as
applicable, at its address set forth on page 1 of this Lease as said address may
be changed form time to time as hereinafter provided. After Tenant shall occupy
the demised premises, the address of Tenant for Notices shall be the Building.
By giving the other party at least ten days prior written notice, either party
may, by Notice given as above provided, designate a different address or
addresses for Notices.

            31.02. Any Notice shall be deemed given as of the date of delivery
as indicated on the return receipt; and in the case of failure to deliver by
reason of changed address of which no Notice was given or refusal to accept
delivery, as of the date of such failure as indicated on the return receipt or
by notice of the postal department.

            31.03. In addition to the foregoing, either Landlord or Tenant may,
from time to time, request in writing that the other party serve a copy of any
Notice on one other person or entity designated in such request, such service to
be effected as provided in Section 31.01 hereof.

                                   ARTICLE 32

                                    NO WAIVER

            32.01. No agreement to accept a surrender of this Lease shall be
valid unless in writing signed by Landlord. No employee of Landlord or of
Landlord's agents shall have any power to accept the keys of the demised
premises prior to the termination of this Lease. The delivery of keys to any
employee of Landlord or of Landlord's agent shall not operate as a termination
of this Lease or a surrender of the demised premises. In the event of Tenant at
any time desiring to have Landlord sublet the premises for Tenant's account,
Landlord or Landlord's agents are authorized to receive said keys for such
purpose without releasing Tenant from any of the obligations under this Lease.
The failure of Landlord to seek redress for violation of, or to insist upon the
strict performance of, any covenant or condition of this Lease or any of the
Rules and Regulations set forth herein, or hereafter adopted by Landlord, shall
not prevent a subsequent act, which would have originally constituted a
violation, from having all the force and effect of an original violation. The
receipt by Landlord of rent with knowledge of the breach of any covenant of this
Lease shall not be deemed a waiver of such breach. The failure of Landlord to
enforce any of the Rules and Regulations set forth herein, or hereafter adopted,
against Tenant and/or any other tenant in the Building shall not be deemed a
waiver of any such Rules and Regulations. No provision of this Lease shall be
deemed to have been waived by Landlord, unless such waiver be in writing signed
by Landlord. No payment by Tenant or receipt by Landlord of a lesser amount than
the monthly rent herein stipulated shall be deemed to be other than on the
account of the earliest stipulated rent, nor shall any endorsement or statement
on any check or any letter accompanying any check or payment of rent be deemed
an accord and satisfaction, and Landlord may accept such check or payment
without prejudice to Landlord's right to recover the balance of such rent or
pursue any other remedy in this Lease provided.

            32.02. This Lease contains the entire agreement between the parties,
and any executory agreement hereafter made shall be ineffective to change,
modify, discharge or effect an abandonment of it in whole or in part unless such
executory agreement is in writing and signed by the party against whom
enforcement of the change, modification, discharge or abandonment is sought.

            34.01. If, by reason of (1) strike, (2) labor troubles, (3)
governmental pre-emption in connection with a national emergency, (4) any rule,
order or regulation of any governmental agency, (5) conditions of supply or
demand which are affected by war or other national, state or municipal
emergency, or any other cause or (6) fire or other casualty, (7) adjustment of
insurance claims, (8) acts of God, or (9) any other cause beyond Landlord's
reasonable control (collectively "Force Majeure Causes"), Landlord shall be
unable to fulfill its obligations under this Lease or shall be unable to supply
any service which Landlord is obligated to supply, this Lease and Tenant's
obligation to pay rent hereunder shall in no wise be affected, impaired or
excused.

                                   ARTICLE 35

                         NO REPRESENTATIONS BY LANDLORD

            35.01. Landlord or Landlord's agents have made no representations or
promises with respect to the Building or demised premises except as herein
expressly set forth.

            36.01. The name of the Building shall be One Exchange Plaza.
Landlord shall have the full right at any time to name and change the name of
the Building and to change the designated address of the Building. The Building
may be named after any person, firm, or otherwise, whether or not such name is,
or resembles, the name of a tenant of the Building.

                                   ARBITRATION

            37.01. In each case specified in this Lease in which resort to
arbitration shall be required, such arbitration (unless otherwise specifically
provided in other Sections of this Lease) shall be in New York City in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association and the provisions of this Lease. The decision and award of the
arbitrators shall be in writing, shall be final and conclusive on the parties,
and counterpart copies thereof shall be delivered to each of the parties. In
rendering such decision and awards, the arbitrators shall not add to, subtract
from or otherwise modify the provisions of this Lease. Judgment may be had on
the decision and award of the arbitrators so rendered in any court of competent
jurisdiction.

                                   ARTICLE 38

                                    INDEMNITY

            38.01. Tenant shall indemnify Landlord and save it harmless from and
against any and all liability, damages, costs or expenses, including attorneys'
fees, arising from any act, omission, or negligence of Tenant or its officers,
contractors, licensees, agents, employees, guests, invitees, or visitors in or
about the Building or arising from any breach or default under this Lease by
Tenant, or arising from any accident, injury, or damage, howsoever and by
whomsoever caused, to any person or property, occurring in


                                       58

Tenant responsible for loss, damage, liability or expense resulting from
injuries to third parties caused by the negligence of Landlord, or its officers,

                               MEMORANDUM OF LEASE

            39.01. Tenant shall, at the request of Landlord execute and deliver
a statutory form of memorandum of this Lease for the purpose of recording, but
said memorandum of this Lease shall not in any circumstances be deemed to modify
or to change any of the provisions of this Lease.

                                   ARTICLE 40

                         APPROVAL OF PERMANENT MORTGAGEE

            40.01. This Lease is conditioned on Landlord obtaining the approval
of this Lease (hereinafter referred to as "Approval") by the holder of the
construction and/or permanent first mortgage on the Land and Building or a
commitment therefor (the "Mortgagee"). Landlord represents that it will use
reasonable efforts to obtain the Approval.

            40.02. In the event Landlord has not obtained the Approval within 15
days after the date hereof, Landlord shall have the obligation to terminate this
Lease upon 7 days' notice to Tenant and this Lease shall terminate upon the
expiration of 7 days after the date of such notice.

            40.03. In the event a Mortgagee notifies Landlord that it will not
give the Approval, then Landlord shall have the right to terminate this Lease by
written notice to Tenant, and upon the giving of such notice, this Lease shall
terminate.

            40.04. In the event of the termination of this Lease pursuant to
Sections 40.02 or 40.03 hereof, and upon such termination, all further
obligations of the parties hereunder shall end and neither Landlord or Tenant
shall


                                       59
<PAGE>

have any liability to the other, except Landlord shall refund any pre-paid rent
and/or security deposit to Tenant.

            40.05. In the event that the Approval is not obtained, Landlord will
reimburse Tenant for any of its reasonable out-of-pocket architectural fees
incurred in connection with the demised premises.

                                   ARTICLE 41

                                SECURITY DEPOSIT

            41.01. Tenant has deposited with Landlord an unconditional,
irrevocable letter of credit substantially in the form attached hereto as
Schedule G in an amount equal to two monthly installments of fixed annual rent,
as security for the full and punctual performance by Tenant of all of the terms
of this Lease. In the event Tenant defaults in the performance of any of the
terms of this Lease, Landlord may draw upon the letter of credit in full and any
amounts not applied as hereinafter provided shall be held by Landlord subject to
and in accordance with the provisions of this Article. Landlord may then apply
the whole or any part of the security so drawn upon to the extent required for
the payment of (i) any rent or (ii) any sum which Landlord may expend or may be
required to expend by reason of Tenant's default including, without limitation,
any damages or deficiency in the re-letting of the demised premises, whether
accruing before or after summary proceedings or other re-entry by Landlord. Upon
each such application, Tenant shall, on demand, pay to Landlord the sum so
applied in cash which shall be added to the remaining proceeds from the letter
of credit so that the security held by Landlord shall be restored to the amount
first set forth above. If Tenant shall fully and punctually comply with all of
the terms of this Lease, the letter of credit or the amount of the security
deposit, as the case may be, shall be returned to Tenant after the termination
of this Lease, delivery of exclusive possession of the Premises to Landlord and
the payment to Landlord of the balance of Tenant's Expense Payment and Tax
Payment for the final Operating Year and Tax Year. In the event of a sale or
lease of the Building, Landlord shall have the right to transfer the letter of
credit or the security deposit to the vendee or lessee and Landlord shall ipso
facto be released by Tenant from all liability for the return of such security;
and Tenant agrees to look solely to the new landlord for the return of said
security and it is agreed that the provisions hereof shall


                                       60
<PAGE>

apply to every transfer or assignment made of the letter of credit or security
to a new landlord. If 30 days prior to the date of such sale, Landlord shall be
holding a letter of credit as Tenant's security, Tenant will upon 5 days' prior
written notice, deliver a substitute letter of credit naming the new landlord as
the new beneficiary thereof. In the event Tenant shall default on such
obligation, Landlord may draw upon the letter of credit and transfer the
proceeds thereof to the new landlord. Tenant shall not assign or encumber or
attempt to assign or encumber the monies deposited herein as security and
neither Landlord nor its successors or assigns shall be bound by any such
assignment, encumbrance, or attempted assignment or encumbrance. In the event
the letter of credit referred to above or any substitute letter of credit is not
renewed so that at all times the letter of credit held by Landlord hereunder is
valid for a period in excess of 30 days, Landlord may draw upon said letter of
credit and hold the proceeds thereof subject to and in accordance with the terms
of this Section. Anything to the contrary contained herein notwithstanding, if
Tenant shall fully and punctually comply with all the terms of this Lease for
two years following the Commencement Date, Landlord shall within 30 days
thereafter return the letter of credit to Tenant upon receiving (a) a substitute
letter of credit with an expiration date no earlier than one year from the date
of such letter of credit and in substantially the same form as the letter of
credit initially deposited with Landlord hereunder but in an amount equal to one
monthly installment of fixed annual rent, and (b) a receipt for the original
letter of credit from Tenant. The substitute letter of credit shall be held and
applied subject to and in accordance with the terms of this Article 41.

                                   ARTICLE 42

                     FAIR MARKET RENT REVIEW/RENEWAL OPTION

            42.01. On the fifth anniversary of the Commencement Date (the
"Review Date"), the fixed annual rent payable pursuant to Article 1 shall be
increased so as to equal the lesser of (i) the fair market rent for the demised
premises as determined in the manner hereinafter provided, or (ii) 125% of the
fixed annual rent payable under Article 1 hereof immediately prior to such
Review Date; provided, however, that in no event may the fixed annual rent
payable under Article 1 hereof be reduced by the operation of this Article 42.


                                       61
<PAGE>

            42.02. If in Landlord's opinion an increase in the fixed annual rent
is warranted because the fair market rent for the demised premises has
increased, Landlord shall give Tenant notice thereof (hereinafter called the
"Review Notice") which Review Notice shall specify the new increased fixed
annual rent that Tenant shall be obligated to pay. The increased fixed annual
rent set forth in the Review Notice shall be effective as of the Review Date to
which such Review Notice relates.

            42.03. (a) If Landlord gives a Review Notice, then at any time
within 15 days after the giving of such Review Notice, Tenant may dispute the
fair market rent for the demised premises as determined by Landlord by giving
notice to Landlord that it is initiating the appraisal process provided for
herein and specifying in such Notice the name and address of the arbitrator
designated by Tenant to act on its behalf. Within 15 days after the designation
of Tenant's arbitrator, Landlord shall give notice to Tenant specifying the name
and address of Landlord's arbitrator. The two arbitrators so chosen shall meet
within 10 days after the second arbitrator is appointed and if, within 20 days
after the second arbitrator is appointed, the two arbitrators shall not agree
upon a determination in accordance with Paragraph (c) of this Section 42.03 they
shall together appoint a third arbitrator. If said two arbitrators cannot
agree upon the appointment of a third arbitrator within 10 days after the
expiration of such 20 day period, then either party, on behalf of both, and on
notice to the other may request such appointment by the American Arbitration
Association (or any successor organization) in accordance with its then
prevailing rules. If the American Arbitration Association shall fail to appoint
said third arbitrator within 10 days after such request is made, then either
party may apply, on notice to the other, to the Supreme Court, New York County,
New York (or any other court having jurisdiction and exercising functions
similar to those now exercised by the foregoing court) for the appointment of
such third arbitrator.

                  (b) Each of the arbitrators selected as herein provided shall
have at least five years experience in the leasing or management of office space
in the "Downtown" office market in the Borough of Manhattan. Each party shall
pay the fees and expenses of the arbitrator selected by it. The fees and
expenses of the third arbitrator and all other expenses (not including the
attorney's fees, witness fees and similar expenses of the parties which shall be
borne separately by each of the parties) of the arbitration shall be borne
equally by the parties hereto.


                                       62
<PAGE>

                  (c) The majority of the arbitrators shall determine the fair
market rent of the demised premises as of the later of the Review Date or the
date a Review notice is given and render a decision and award as to their
determination to both Landlord and Tenant within 20 days after the appointment
of the third arbitrator. In rendering such decision and award, the arbitrators
shall assume or take into consideration as appropriate all of the following: (i)
the Landlord and prospective tenant are typically motivated; (ii) the Landlord
and prospective tenant are well informed and well advised and each is acting in
what it considers its own best interest; (iii) a reasonable time under
then-existing market conditions is allowed for exposure of the demised premises
on the open market; (iv) the rent is unaffected by concessions, special
financing amounts and/or terms, or unusual services, fees, costs or credits in
connection with the leasing transaction; (v) the demised premises are fit for
immediate occupancy and use "as is" and require no additional work by Landlord
and that no work has been carried out thereon by the Tenant, its subtenant, or
their predecessors in interest during the Term which was diminished the rental
value of the demised premises; (vi) in the event the demised premises have been
destroyed or damaged by fire or other casualty, they have been fully restored;
(vii) that the demised premises are to be let with vacant possession and subject
to the provisions of this Lease (assuming, however, that the Base Tax and
Expense Base Factor are the same as those specified in Article 3 hereof) for a
five-year term; and (viii) market rents then being charged for comparable space
in other similar office buildings in the same area. For example, if (i) the fair
market rent for the demised premises were $50 per square foot on the Review Date
if one assumed a Base Tax and Expense Base Factor which would be used in leases
generally entered into at the time such fair market rent is being determined,
(ii) escalations for Taxes and Expenses from the Base Tax and Expense Base
Factor contained in the Lease at the time when fair market rent is being
determined are $5 per square foot and (iii) the initial fixed annual rent
payable hereunder were $40 per square foot, then (a) the fair market rent for
the demised premises on the assumptions set forth above (including assumption
vii) would be $45 per square foot (i.e. the $50 per square foot less the $5 of
escalations) and the increase to bring Tenant's fixed annual rent to fair market
rent would be $5 per square foot. In rendering such decision and award, the
arbitrators shall not modify the provisions of this Lease. The decision and
award of the arbitrators shall be in writing and be final and conclusive on all
parties and counterpart copies thereof shall be delivered to each of said
parties. Judgment may be had on the decision and award of the


                                       63
<PAGE>

arbitrators so rendered in any court of competent jurisdiction.

                  (d) Prior to the determination of the arbitrators, Tenant
shall pay as the fixed annual rent it is obligated to pay under this Lease the
amount set forth in the Review Notice and in the event the arbitrators determine
that the fixed annual rent payable pursuant to this Article 42 is greater than
that set forth in the Review Notice, then Tenant shall promptly pay to Landlord
the amount of its underpayment of fixed annual rent for the period commencing on
the Review Date, or if the arbitrators determine that the fixed annual rent
payable pursuant to this Article 42 is less than that set forth in the Review
Notice, then Tenant shall be entitled to a credit in the amount of its
overpayment for the period commencing on the Review Date against subsequent
payments of fixed annual rent due hereunder. In the event the arbitrators
determine that the rent set forth in Landlord's Review Notice is more than 110%
of the rent which should be payable to Landlord pursuant to the provisions of
this Article 42, Tenant shall be entitled to receive an additional credit
against fixed annual rent by reason of any overpayment of fixed annual rent paid
by Tenant under this paragraph (d) equal to interest on the amount of any such
overpayment to the extent paid by Tenant at the rate being paid by Republic
National Bank or, if Republic National Bank shall cease to exist, a Substitute
Bank (as defined in Article 22) on 30-Day Certificates of Deposit at the time
such overpayment is made from the date paid by Tenant to the date credit for
such overpayment is taken. In no event shall the fixed annual rent (as the same
may have been increased from time to time in accordance with this Article 42) be
reduced pursuant to this Article 42.

                  (e) Nothing contained in this Article 42 shall be deemed in
any way to alter or modify the provisions or Article 3 hereof.

            42.04. (a) Tenant shall have an option (the "Option") to extend the
term of the Lease for one (1) additional term of five (5) years (the "Renewal
Term") commencing on the first day next succeeding the Expiration Date upon the
same terms, conditions and provisions as are provided for in the Lease
(including, without limitation, the same Base Tax and Expense Base Factor but
excluding this Section 42.04 and Section 2.07 hereof) except that the fixed
annual rent payable pursuant to Article 1 hereof for the Renewal Term shall be
the greater of (i) the fixed annual rent payable thereunder immediately prior to
the Expiration Date, or (ii) the fair market rent for the demised premises


                                       64
<PAGE>

as of such Expiration Date determined in the manner provided in paragraph (c)
below.

                  (b) The Option may be exercised only by Tenant giving written
notice to Landlord of Tenant's exercise of said Option by Certified Mail, return
receipt requested, not more than fourteen (14) nor less than nine (9) months
prior to the Expiration Date of the Term (the "Exercise Notice"). Upon Tenant's
giving of the Exercise Notice, the term of this Lease shall be extended
automatically upon the terms and conditions herein specified without the
execution of an extension agreement or other instrument. It is expressly agreed
that Tenant shall have only one opportunity to exercise the Option. If Tenant
shall not give Landlord the Exercise Notice at the time and in the manner set
forth above, the Option shall terminate and be deemed waived by Tenant. Time is
of the essence as to the date for the giving of the Exercise Notice.

                  (c) After Landlord receives the Exercise Notice, and if in
Landlord's opinion an increase in the fixed annual rent for the Renewal Term is
warranted because the fair market rent for the demised premises has increased,
Landlord shall send Tenant a Review Notice stating the amount which, in
Landlord's opinion, shall constitute the fair market rent for the demised
premises as of the Expiration Date. The increased fixed annual rent set forth in
the Revised Rent Notice shall be effective as of the first date of the Renewal
Term. The provisions of Section 42.03 shall apply to any disputes as to the fair
market rent specified by Landlord in the Review Notice with respect to the
Renewal Term with all references to the Review Date being deemed to refer to the
first day of the Renewal Term.

            42.05. Notwithstanding the foregoing provisions of this Article 42,
if on the date that Tenant exercises the Option, or if on any subsequent date up
to and including the Expiration Date, Tenant is in default in the performance of
any of the terms, conditions or provisions of this Lease and such default has
continued beyond the applicable grace period herein provided, than Tenant's
exercise of the Option and the extension of the Term of this Lease contemplated
thereby shall, at the option of Landlord exercised by written notice to Tenant,
be rendered null and void and shall be of no further force and effect and Tenant
shall have no further or additional right to exercise the Option, all of which
shall be deemed waived by Tenant.

            42.06. If Tenant exercises the Option, or if the fixed annual rent
payable under Article 1 hereof is increased pursuant to the operation of
Sections 42.01 --


                                       65
<PAGE>

42.03 hereof, then, at Landlord's request, Tenant agrees within ten (10) days
after such request is made to execute, acknowledge and deliver to Landlord an
instrument in form and substance reasonably satisfactory to Landlord, confirming
(i) the extension of the Term, (ii) the increased fixed annual rent payable
under this Lease pursuant to this Article 42, and (iii) the other modifications
provided for in this Article 42, but no such instrument shall be required in
order to make the provisions hereof effective.

                                   ARTICLE 43

                                  MISCELLANEOUS

            43.01. Irrespective of the place of execution or performance, this
Lease shall be governed by and construed in accordance with the laws of the
State of New York.

            43.02. This Lease shall be construed without regard to any
presumption or other rule requiring construction against the party causing this
Lease to be drafted.

            43.03. Except as otherwise expressly provided in this Lease, each
covenant, agreement, obligation or other provision of this Lease on Tenant's
part to be performed shall be deemed and construed as a separate and independent
covenant of Tenant, not dependent on any other provision of this Lease.

            43.04. All terms and words used in this Lease, regardless of the
number or gender in which they are used, shall be deemed to include any other
number and any other gender as the context may require.

            43.05. Time shall be of the essence with respect to the exercise of
any option on the part of Tenant to extend the term of this Lease.

            43.06. Except as otherwise provided herein whenever payment of
interest is required by the terms hereof it shall be at the Interest Rate.

            43.07. If the demised premises or any additional space to be
included within the demised premises shall not be available for occupancy by
Tenant on the specific date hereinbefore designated for the commencement of the
term of this Lease or for the inclusion of such space for any reason


                                       66
<PAGE>

whatsoever, then this Lease shall not be affected thereby but, in such case,
said specific date shall be deemed to be postponed until the date when the
demised premises or such additional space shall be available for occupancy by
Tenant, and Tenant shall not be entitled to possession of the demised premises
or such additional space until the same are available for occupancy by Tenant;
provided, however, Tenant shall have no claim against Landlord, and Landlord
shall have no liability to Tenant by reason of any such postponement of said
specific date, and the parties hereto further agree that any failure to have the
demised premises or such additional space available for occupancy by Tenant on
said specific date or on the Commencement Date shall in no way affect the
obligations of Tenant hereunder nor shall the same be construed in any way to
extend the Term. This Section 42.07 shall be deemed to be an express provision
to the contrary of Section 223-a of the Real Property Law of the State of New
York and any other law of like import now or hereafter in force.

            43.08 In the event that Tenant is in arrears in payment of fixed
annual rent or additional rent hereunder, Tenant waives Tenant's right, if any,
to designate the items against which any payments made by Tenant are to be
credited, and Tenant agrees that Landlord may apply any payments made by Tenant
to any items it sees fit, irrespective of and notwithstanding any designation or
request by Tenant as to the items against which any such payments shall be
credited.

            43.09. All Exhibits referred to in this Lease are hereby
incorporated in this Lease by reference.

            43.10. The covenants, conditions and agreements contained in this
Lease shall bind and inure to the benefit of Landlord and Tenant and their
respective heirs, distributees, executors, administrators, successors, and
except as otherwise provided in this lease, their assigns.

            43.11. No remedy or election hereunder shall be deemed exclusive but
shall, whenever possible, be cumulative with all other remedies at law or in
equity.

            43.12. Under no circumstances shall Tenant record a copy of this
Lease without Landlord's prior written consent.

                                   PARTNERSHIP

            45.01. The liability of each of the general partners of the
partnership Tenant shall be joint and several. The technical dissolution of
Tenant (or of any of the partnerships constituting Tenant) by reason of the
death, retirement, resignation, bankruptcy or adjudication of incompetency of
one or more partners, shall not affect this Lease or the liability thereunder of
the general partners, and Tenant agrees that the partnership shall nevertheless
continue as Tenant with respect to the remaining general partner(s).

            45.02. Simultaneously with execution of this Lease by Landlord and
Tenant, Tenant has delivered to Landlord a list of the names and addresses of
all existing general partners of the partnership Tenant. In the event Tenant
admits any new general partner(s) (a "New General Partner"), Tenant agrees,
within thirty (30) days thereafter, to give notice to Landlord of that fact and
of the name and address (residence address, if an individual) of each New
General Partner(s), together with such reasonable proof as Landlord shall
require that all of such New General Partner(s) have in writing assumed
performance of Tenant's obligations under this Lease. The admission of any new
partner or withdrawal of any partners pursuant to paragraph 45.04 below shall
constitute a permitted assignment under Article 11 hereof.

            45.03. In the event of a merger or consolidation with another firm,
Tenant agrees, within thirty (30) days thereafter, to give notice to Landlord of
that fact and all of the names and addresses (residence address, if individuals)
of the New General Partners of the merged or consolidated firm, together with
such reasonable proof as Landlord shall require that all of such New General
Partners


                                       68

have in writing assumed performance of Tenant's obligations under this Lease.

            IN WITNESS WHEREOF, Landlord and Tenant have respectively executed
this Lease as of the day and year first above written.

            AGREEMENT made as of the 1st day of May, 1993, between THE
PRUDENTIAL INSURANCE COMPANY OF AMERICA, a New Jersey corporation, having an
office at 10 Rockefeller Plaza, New York, New York 10022 ("Landlord") and LA

                              W I T N E S S E T H

            WHEREAS:

            (A) Landlord is the owner of premises located at One Exchange Plaza,
New York, New York ("Building").

            (B) Tenant is the tenant of a portion of the twenty-sixth floor of
the Building ("Demised Premises") pursuant to that certain Agreement of Lease
("Lease"), dated as of January 6, 1984, between Aetna Life Insurance Company and
Tenant.

            (C) Tenant has requested that Landlord extend the term of the Lease

            NOW, THEREFORE, in consideration of the mutual covenants and
conditions herein contained, the parties hereto hereby agree as follows:
<PAGE>

            1. The term of the Lease, as modified hereby, is hereby extended to

<PAGE>

      9. The following Articles, Exhibits and Schedules of the Lease are hereby
deleted in their entirety: 39, Schedule C, Schedule F, Exhibit 1 and Exhibit 2.

      10. With respect to Article 41 of the Lease, the amount of the security
deposit referred to therein shall be changed from $24,648.00 to $76,500 and the

Credit as required hereunder and pursuant to Article 41 of the Lease, except as
amended herein.

      11. A. Tenant, at Tenant's expense, subject to paragraph 1(3) below, shall
prepare a preliminary plan or set of plans and preliminary specifications (which
said preliminary plan or set of plans, as the case may be, and specifications
are hereinafter called the "Plans") which shall contain complete information
(including engineering required) and dimensions necessary and sufficient for the
construction and finishing of the Demised Premises. The Plans shall be submitted
by Tenant to Landlord upon execution and delivery of this Agreement. Any
revisions to the Plans reasonably required by Landlord shall be performed by
Tenant within five (5) business days after demand by Landlord.

installations (herein called "Tenant's Work") specified in Schedule B annexed
hereto (which unless otherwise specifically provided herein, shall include such
removal as may be required of existing installations).

      Notwithstanding any provision of the Lease or this Agreement to the

            B. The term "Work Cost" as used in this Article shall mean the
actual cost (including the cost of applicable insurance premiums and the cost of

for Tenant's


                                      -3-
<PAGE>

occupancy. The specification of Tenant's Work in Schedule B represents the limit
of Landlord's responsibilities in connection with the preparation of the Demised
Premises and except as so provided, Tenant shall take the Demised Premises
"AS-IS". Any other improvements, alterations or additions shall be performed by
Tenant at Tenant's sole cost and expense, but subject to all of the terms,
conditions and covenants of this Agreement.

            E. Tenant has made and makes no representation of the date on which
it will substantially complete Tenant's Work and, Tenant acknowledges and agrees
that Landlord shall be under no penalty or liability to Tenant whatsoever by
reason of any delay in such performance and the Lease shall not be affected
thereby. The term of the Lease shall commence on the Commencement Date. Tenant
shall, at no cost to Landlord, execute a confirmatory letter establishing the
actual commencement date, promptly after Landlord's request for same.

            F. Tenant shall be permitted to enter into the Demised Premises for
installation of its machinery, equipment and fixtures and performance of its
work, all as permitted by the Lease, prior to the Commencement Date at its sole
risk.

            G. All work performed by Tenant, including the building air
conditioning installation, shall, upon installation, become Landlord's property
and shall be surrendered at the expiration or sooner termination of the term of
the Lease, in good condition, reasonable wear and tear excepted; provided,
however, that Tenant shall have the right to remove trade fixtures, equipment
and personal property. Tenant shall repair all damage occasioned by such
removal.

            H. For the purposes of this Article, Tenant's Work shall be deemed
to be substantially completed when all major construction is completed as
determined by Tenant's architect (as hereinafter defined), life safety systems
operable, the Demised Premises is locked and secured, and there is beneficial
occupancy although minor items of construction or improvements which do not
unreasonably interfere with Tenant's ability to carry on its business in the
Demised Premises have not been completed. Landlord's construction representative
shall periodically inspect Tenant's Work to determine that (i) Tenant's Work is
being done in accordance with the Plans or (ii) any changes do not adversely
affect the structural components of the building or the building systems. If
Landlord's construction representative reasonably determines that Tenant's Work
does not comply with clauses (i) or (ii) above, Landlord's construction
representative may object to such work by notice to Tenant, which notice shall
specify the nature of such objection. Tenant agrees to promptly comply with and
remedy all objections raised by Landlord's construction representative,

            I. 1. Notwithstanding anything contained to the contrary in this
Lease, the total cost of Tenant's Work which Landlord shall provide Tenant
without charge and for building installations performed prior to the
Commencement Date shall be FOUR HUNDRED FOUR THOUSAND DOLLARS ($404,000.00) (the
"Cap"). If the Work Cost shall exceed the Cap, Tenant expressly acknowledges and
agrees that it shall be solely responsible


                                      -4-
<PAGE>

for payment of all costs above the Cap. Tenant hereby expressly acknowledges
that, if the Work Cost is less than the Cap, the Landlord shall retain the
difference, it being understood that there shall be no rent concessions or
abatements in Tenant's favor.

                  2. In addition to the Cap, Landlord shall contribute an
additional $10,000 toward any renovations in the Demised Premises required by
the Americans with Disabilities Act ("ADA") or any other law or governmental
regulation. Tenant acknowledges and agrees that the common area bathrooms shall
comply with the ADA.

                  3. Landlord shall contribute an amount not to exceed $36,000
in addition to the Cap toward preparation of construction drawings, filing fees,
expediters fees and similar "soft" costs. All costs incurred by Tenant for
tenant changes shall be at Tenant's sole cost and expense.

            J. Tenant hereby advises Landlord that the estimated total "hard"
cost of performing Tenant's Work is $600,000.00 (the "Total Cost"). Tenant also
advises Landlord that it is Tenant's intention to engage LCG Architects as its
architect. Landlord hereby acknowledges that LCG Architects is acceptable to
Landlord. Tenant covenants and agrees that if, for whatever reason, or for no
reason, it either does not engage LCG Architects as its architect or if LCG
Architects ceases to function as the Tenant's architect, any other architect
which Tenant may desire to engage, may only be engaged with the prior written
consent of the Landlord, which such consent shall not be unreasonably withheld
or delayed (as such, LCG Architects or such other architect selected by Tenant
and approved by Landlord, shall be hereinafter referred to as "Tenant's
Architect."). The sum(s) to be paid by the Landlord, pursuant to Article 1
hereof, shall be paid as follows:

                  1. Tenant's Architect shall periodically (but not more often
than once each month) certify in writing to both Tenant and to Landlord, (i) the
cost of Tenant's Work completed to the date of such certification less the cost
of Tenant's Work previously certified by Tenant's Architect as being completed
(the "Payment Amount"), (ii) an estimate as the amount of the Total Cost
remaining and (iii) that the Tenant's Work has been performed in accordance with
the Plans. Within five (5) business days from receipt of each such
certification, Landlord shall pay to Tenant the Payment Amount. In addition, in
the event that the cost of compliance of the Tenant's Work with the requirements
of the ADA is less than $10,000, then, upon certification that such compliance
has been completed, the Tenant's Architect shall also indicate the cost of such
compliance, and the Landlord shall pay such sum to the Tenant. If such
compliance cost exceeds the said $10,000, then Landlord shall pay the sum of
$10,000 to the Tenant.

                  2. Within five (5) business days after receipt by the Landlord
of a written statement (certified as true, complete and accurate by the
president or the Chief Executive Officer of the Tenant) from the Tenant
specifying the amount of the "soft" costs (for example, preparation of Plans,
filing fees, expediter fees and similar costs and fees) required for the
performance of Tenant's Work, Landlord shall deliver to Tenant its check


                                      -5-
<PAGE>

in such amount up to a maximum or $36,000. To the extent that the amount of
Tenant's soft costs is less than $36,000, the difference will be added to the
Cap.

                  3. Each time the Landlord advances monies to the Tenant
pursuant to paragraph J1., above, Tenant shall, in exchange for such monies,
deliver to the Landlord fully executed and acknowledged lien waivers from such
contractor, subcontractor, materialmen and suppliers (each a "Contractor") to be
paid, each lien waiver to indicate the amount which each such Contractor has
received to the date or such payment. Upon final completion of Tenant's Work,
Tenant shall promptly deliver final lien waivers from each Contractor.

            K. Landlord shall provide Tenant with a list of four (4) approved
contractors from which such list, Tenant agrees to select one such contractor to
perform Tenant's Work. In the event Tenant is dissatisfied with the bids that
are submitted by the contractors on such list, then, Tenant shall promptly try
to obtain a contractor to perform Tenant's Work and shall submit the name,
address and such other information as may be reasonably required by Landlord
concerning such new general contractor. Landlord agrees that it will not
unreasonably withhold its consent to the utilization by Tenant of such general
contractor not on the aforementioned list of four (4) general contractors.
Tenant specifically acknowledges and agrees that the Tenant and the general
contractor shall not permit any mechanics liens or contractor/materialmen's
liens to be placed against the Building. Moreover, Tenant acknowledges and
agrees that any general contractor selected by Tenant to perform Tenant's Work
must provide the requisite property, public liability, workmen's compensation
and any and all other insurance required by law which such insurance shall be in
an amount at least equal to three (3) times the total amount of the cost of
Tenant's Work, which such insurance shall also name Landlord as an additional
insured.

      12. Tenant presently occupies part of the 26th floor of the Building. If
and only if this Agreement is executed and unconditionally delivered by Landlord
and Tenant, then the original Expiration Date (as such term is defined in the
Lease) of the Lease shall be deemed to be that date (the "Lease Amended
Expiration Date") which is the day immediately preceding the Commencement Date
of this Agreement, unless sooner terminated pursuant to any of the terms,
covenants and conditions of the Lease or pursuant to law, upon all of the
executory terms, covenants and conditions contained in the Lease (including the
payment of fixed rent and additional rent at the rates set forth therein). In
the event that Tenant shall fail to vacate the 26th floor premises and surrender
same unto Landlord, in accordance with the applicable terms and provisions of
the Lease, on or before the Lease Amended Expiration Date, such failure shall be
deemed a default by Tenant in the performance of a material covenant hereunder,
upon which Landlord shall have the right to exercise any and all rights and
remedies afforded Landlord under the Lease, including, but not limited to, the
recovery of damages incurred by Landlord by reason of claims of any new or
prospective tenant of the aforesaid 26th floor premises arising from Tenant's
holding-over, or the termination of any new Lease with respect to said premises
by reason of Landlord's inability to timely deliver possession of said premises
to any new tenant. The foregoing


                                      -6-
<PAGE>

extension of the term of the Lease shall be of no force or effect in the event
that this Agreement is not executed and unconditionally delivered by Landlord
and Tenant for any reason whatsoever, including Landlord's willful refusal to
execute this Agreement.

      13. Schedule F of the Lease is deemed deleted and replaced with Schedule C
annexed hereto and made a part hereof.

      14. Except as expressly modified herein, all terms, conditions,
provisions, rights and obligations set forth in the Lease, as amended, shall
continue in full force and effect, and Tenant hereby ratifies said Lease, as
amended, and agrees and acknowledges that there are no defaults, defenses,
claims, counterclaims, set-offs or actions available against the Landlord or
Landlord's predecessors in interest arising out of said Lease, as amended. All
defined terms used herein, unless defined herein, shall have the same meaning
ascribed to them in the Lease.

      15. The covenants, agreements, terms and conditions contained in this
Agreement shall bind and inure to the benefit of the parties hereto and except
as otherwise specifically provided in the Lease, as amended, their respective
legal successors and assigns.

      16. Any and all notices, demands or other communications between Tenant,
Landlord and Landlord's construction representative shall be deemed effective
only if in writing, forwarded to the parties hereto at their respective
addresses set forth above, or hereinafter provided in writing to Landlord or to
Tenant, as the case may be. Such notices may be by telecopier or fax, personal
delivery, or certified mail return receipt requested and the effective date of
any such notice shall be the date on which such notice was received by the party
to whom it was addressed. Copies of any and all such notices, demands or other
written communication shall be forwarded to Tenant's counsel, Fulbright &
Jaworski, L.L.P., Attention: Thomas E. McHugh, Jr., Esq., 666 Fifth Avenue, New
York, New York 10103-3198 (Facsimile #(212) 752-5958) and copies of any and all
such notices demands or other written requests shall be forwarded to Landlord's
counsel, Parker Duryee Rosoff & Haft, P.C., Attention: Daniel B. Zanini, Esq.,
529 Fifth Avenue, New York, New York 10017 (Telecopier #(212) 972-9487).

      17. Landlord and Tenant agree that, based solely on the Plans, Tenant's
Work does not include any sufficiently unique or unusual construction or
installation, such that Tenant would be obliged to remove any or all of Tenant's
Work at the termination of the Lease as modified by this Agreement. However, in
the event that the final plans and specifications, or any change orders thereto,
add any unique or unusual construction or installation, as reasonably determined
by the Landlord, Tenant hereby agrees that at the termination of the Lease as
modified by this Agreement, that it will, at its sole cost and expense, remove
such unique or unusual construction or installation(s).

      18. This Agreement may not be changed orally but only in writing signed by
the party against whom enforcement is sought.

      WHEREAS, Tenant has requested that Landlord extend the Demised Premises
under the Lease to include the entire twenty-fourth (24th) floor in the Property
and to modify certain other provisions of the Lease, and Landlord has agreed to
do so subject to and in accordance with the terms, provisions and conditions of
this Agreement;

      NOW, THEREFORE, in consideration of the mutual covenants, promises,
conditions and provisions herein contained, the value and adequacy of which are
hereby acknowledged by both parties hereto, the parties hereto hereby agree as
follows:

      1. The term "Demised Premises" originally defined in the "Witnesseth"
paragraph of the original 1984 lease agreement, as modified by paragraph one of
the Second Amendment, referred to above, is now hereby further modified to
include, in addition to the twenty-fifth (25th) floor in the Property (but not
in substitution therefor) the entire twenty-fourth (24th) floor in the Property,
which together shall from the Possession Date, as hereinafter defined, forward
constitute the Demised Premises. The entire twenty-fourth (24th) floor in the
Property is hereinafter referred to as the "Additional Premises".

      2. With respect to the Additional Premises only, the fixed annual rental
which shall be paid by the Tenant to the Landlord shall be as set forth in
Schedule A of this Agreement, commencing upon the Commencement Date, as

to Landlord for the entire Demised Premises (twenty-fifth (25th) and
twenty-fourth (24th) floors combined) shall be as set forth in Schedule B of
this Agreement.

      3. (a) Landlord and Tenant agree that the Expiration Date, as defined in
the Lease and confirmed in this Agreement, is January 6, 2008 for the entire
Demised Premises. With respect to the Additional Premises only, the Commencement
Date shall be deemed to be the date which is one-hundred eighty (180) days from
the date the Landlord delivers possession of the Additional Premises to Tenant
(the "Possession Date"). Landlord shall give Tenant three (3) days prior written
notice of the actual Possession Date. Tenant agrees to submit complete
construction drawings, plans and specifications pertaining to the build-out of
the twenty-fourth (24th) floor to the Landlord within sixty (60) days from the
date of execution of this Agreement. Landlord shall have such drawings, plans
and specifications reviewed and either approved or have suggested revisions
thereto within twenty (20) days after receipt of such drawings, plans and
specifications.

            (b) If the Possession Date does not occur on or before September 15,
1997, as to which date time is of the essence, Tenant may, at its option,
terminate this Agreement and neither party shall have any right or obligation
arising herefrom other than those set forth in paragraph 8(b) below.

      4. With respect to Article 3, paragraph 3.01 of the Lease, and paragraph 4

                                      -2-

      (ii) the term "Tenant's Tax Share" shall mean 3.05%; and

      (iii) the term "Taxes" shall be supplemented by adding to the definition

Zoning Resolution of the City of New York".

      5. With respect to Article 3, paragraph 3.02 of the Lease and paragraph 5

Letter of Credit shall be modified to conform to the terms of this Agreement,
including, but not limited to, a requirement that Tenant deliver to Landlord,
simultaneously with the delivery of a signed Agreement, an original and
satisfactory clean and irrevocable stand-by Letter of Credit as required
hereunder and pursuant to Article 41 of the Lease, and paragraph 10 of the
Second Amendment, except as amended herein.

      7. A. Tenant, at Tenant's expense, subject to paragraph 1 below, shall
prepare preliminary construction drawings, plans and preliminary specifications
(which said preliminary of drawings, plans, as the case may be, and
specifications are hereinafter called the "Plans") which shall contain complete
information (including engineering required) and dimensions necessary and
sufficient for the construction and finishing of the Additional Premises. The
Plans shall be submitted by Tenant to Landlord within sixty (60) days of the
execution and delivery of this Agreement. Any revisions to the Plans reasonably
required by Landlord shall be performed by Tenant within five (5) business days
after demand by Landlord.

      In accordance with the Plans, Tenant, at Landlord's expense, subject to
the Cap (as hereinafter defined in Paragraph 1 of this Article) and except as
otherwise expressly specified in this Agreement, will cause its designated
contractor to make and complete in and to the Additional Premises the work and
installations (herein called "Tenant's Work") specified in the


                                      -3-
<PAGE>

Plans (which shall include the installation of an inter-connecting interior
staircase between the 25th floor and the Additional Premises). Notwithstanding
the foregoing, Landlord, at its sole expense, shall arrange for the interior
demolition within the Additional Premises prior to the Possession Date.

      Notwithstanding any provision of the Lease or this Agreement to the
contrary, any requests for revisions to the Plans or other notices to be given
to Tenant by Landlord pursuant to this Article may be given to Tenant's
designated representative, Steven C. Berger either (i) delivered personally or
(ii) sent by telecopy to (212) 344-1469 or (iii) sent by certified mail, return
receipt requested, or overnight courier, with receipt acknowledged, to: 55
Broadway, 25th Floor, New York, New York 10006.

            B. Intentionally omitted.

            C. In all instances where Tenant is required to supply information
or authorizations with regard to Landlord's Work, Tenant shall supply the same
within three (3) business days after written request therefor by Landlord.

            D. Except as provided in this Article, Landlord shall not be
required to spend any money or to do any work to prepare the Additional Premises
or the Demised Premises for Tenant's occupancy. Tenant shall take the Additional
Premises "AS-IS". Any other improvements, alterations or additions shall be
performed by Tenant at Tenant's sole cost and expense, but subject to all of the
terms, conditions and covenants of this Agreement.

            E. Tenant has made and makes no representation of the date on which
it will substantially complete Tenant's Work and, Tenant acknowledges and agrees
that Landlord shall be under no penalty or liability to Tenant whatsoever by
reason of any delay in such performance and the Lease shall not be affected
thereby. The term of the Lease shall commence on the Commencement Date. Tenant
shall, at no cost to Landlord, execute a confirmatory letter establishing the
actual commencement date, promptly after Landlord's request for same.

            F. Tenant shall be permitted to enter into the Additional Premises
for installation of its machinery, equipment and fixtures and performance of its
work, all as permitted by the Lease, on the Possession Date at its sole risk,
and provided all other provisions of the Lease, including without limitation,
insurance requirements, are satisfied.

            G. All work performed by Tenant, including the building air
conditioning installation, shall, upon installation, become Landlord's property
and shall be surrendered at the expiration or sooner termination of the term of
the Lease, in good condition, reasonable wear and tear excepted; provided,
however, that Tenant shall have the right to remove trade fixtures, equipment
and personal property. Tenant shall repair all damage occasioned by such
removal.


                                      -4-

            H. Landlord's construction representative shall periodically inspect
Tenant's Work to determine that (i) Tenant's Work is being done in accordance
with the Plans or (ii) any changes do not adversely affect the structural
components of the building or the building systems. If Landlord's construction
representative reasonably determines that Tenant's Work does not comply with
clauses (i) or (ii) above, Landlord's construction representative may object to
such work by notice to Tenant, which notice shall specify the nature of such
objection. Tenant agrees to promptly comply with and remedy all objections
raised by Landlord's construction representative.

            I. Notwithstanding anything contained to the contrary in the Lease,
or in this Agreement, the total cost of Tenant's Work which Landlord shall
provide Tenant without charge and for building installations performed prior to
the Commencement Date shall be THREE HUNDRED SIXTY THOUSAND DOLLARS
($360,000.00) (the "Cap"). If the total cost of Tenant's Work shall exceed the
Cap, Tenant expressly acknowledges and agrees that it shall be solely
responsible for payment of all costs above the Cap. Tenant hereby expressly
acknowledges that, if the Work Cost is less than the Cap, the Landlord shall
retain the difference, it being understood that there shall be no rent
concessions or abatements in Tenant's favor.

            J. Tenant hereby advises Landlord that the estimated total "hard"
cost of performing Tenant's Work is $600,000.00 (the "Total Cost"). Tenant also
advises Landlord that it is Tenant's intention to engage LCG Architects as its
architect. Landlord hereby acknowledges that LCG Architects is acceptable to
Landlord. Tenant covenants and agrees that if, for whatever reason, or for no
reason, it either does not engage LCG Architects as its architect or if LCG
Architects ceases to function as the Tenant's architect, any other architect
which Tenant may desire to engage, may only be engaged with the prior written
consent of the Landlord, which such consent shall not be unreasonably withheld
or delayed (as such, LCG Architects or such other architect selected by Tenant
and approved by Landlord, shall be hereinafter referred to as "Tenant's
Architect"). The sum(s) to be paid by the Landlord, pursuant to Article 1
hereof, shall be paid as follows:

                  1. Tenant's Architect shall periodically (but not more often
than once each month) certify in writing to both Tenant and to Landlord, (i) the
cost of Tenant's Work completed to the date of such certification less the cost
of Tenant's Work previously certified by Tenant's Architect as being completed
(the "Payment Amount"), (ii) an estimate as the amount of the Total Cost
remaining and (iii) that the Tenant's Work has been performed in accordance with
the Plans. Within five (5) business days from receipt of each such
certification, Landlord shall pay to Tenant the Payment Amount.

                  2. Each time the Landlord advances monies to the Tenant
pursuant to paragraph J1., above, Tenant shall, in exchange for such monies,
deliver to the Landlord fully executed and acknowledged lien waivers from such
contractor, subcontractor, materialmen and suppliers (each a "Contractor") to be
paid, each lien waiver to indicate the


                                      -5-
<PAGE>

amount which each such Contractor has received to the date of such payment. Upon
final completion of Tenant's Work, Tenant shall promptly deliver final lien
waivers from each Contractor.

            K. Landlord shall provide Tenant with a list of four (4) approved
contractors from which such list, Tenant agrees to select one such contractor to
perform Tenant's Work. In the event Tenant is dissatisfied with the bids that
are submitted by the contractors on such list, then, Tenant shall promptly try
to obtain a contractor to perform Tenant's Work and shall submit the name,
address and such other information as may be reasonably required by Landlord
concerning such new general contractor. Landlord agrees that it will not
unreasonably withhold its consent to the utilization by Tenant of such general
contractor not on the aforementioned list of four (4) general contractors.
Tenant specifically acknowledges and agrees that the Tenant and the general
contractor shall not permit any mechanics liens or subcontractor/materialmen's
liens to be placed against the Property. Moreover, Tenant acknowledges and
agrees that any general contractor selected by Tenant to perform Tenant's Work
must provide the requisite property, public liability, workmen's compensation
and any and all other insurance required by law which such insurance shall be in
an amount at least equal to three (3) times the total amount of the cost of
Tenant's Work, which such insurance shall also name Landlord as an additional
insured.

      8. (a) Tenant specifically acknowledges that the Additional Premises are
presently the subject of a lease agreement with another tenant. Landlord desires
to terminate that agreement in order to make this Agreement effective. However,
the effectiveness of this Agreement is specifically and expressly conditioned on
the termination of the existing lease covering the Additional Premises. In the
event the existing lease agreement is not terminated, for any reason, then
Landlord shall so notify Tenant in writing, which notice shall be given within
thirty (30) days of the execution and delivery of this Agreement, in which case
this Agreement shall be deemed void ab initio and neither party shall have any
further right or obligation arising here from.

            (b) If this Agreement is rendered a nullity because Tenant has
terminated the Agreement because Landlord failed to deliver possession of the
Additional Premises to Tenant on or before September 15, 1997 or if Landlord
fails to obtain a surrender of the existing lease pursuant to paragraph 8(a)
above, Landlord shall reimburse Tenant for any and all reasonable out-of-pocket
costs and expenses incurred by Tenant in connection with this Agreement and the
Additional Premises, including but not limited to attorney fees, architect's
fees and engineering fees.

      9. Except as expressly modified herein, all terms, conditions, provisions,
rights and obligations set forth in the Lease, as amended, shall continue in
full force and effect, and Tenant hereby ratifies said Lease, as amended, and
agrees and acknowledges that there are no


                                      -6-
<PAGE>

defaults, defenses, claims, counterclaims, set-offs or actions available against
the Landlord or Landlord's predecessors in interest arising out of said Lease,
as amended. All defined terms used herein, unless defined herein, shall have the
same meaning ascribed to them in the Lease.

      10. The covenants, agreements, terms and conditions contained in this
Agreement shall bind and inure to the benefit of the parties hereto and except
as otherwise specifically provided in the Lease, as amended, their respective
legal successors and assigns.

            With respect to paragraph 16 of the Second Amendment pertaining to
Notices, copies of any notices, demands or communications to Tenant shall be
sent to Tenant's counsel, Fulbright & Jaworski LLP, Attention: Douglas Danzig,
Esq.

      11. This Agreement may not be changed orally but only in writing signed by
the party against whom enforcement is sought.

      IN WITNESS WHEREOF, Landlord and Tenant have respectively executed this
Third Amendment to Lease Agreement as of the day and year first above written.

                               LABRANCHE & CO INC.
                              EQUITY INCENTIVE PLAN

         1. PURPOSE. The purpose of the LaBranche & Co Inc. Equity Incentive
Plan (the "Plan") is to establish a flexible vehicle through which LaBranche &
Co Inc., a Delaware corporation (the "Company"), can offer equity-based
compensation incentives to eligible personnel of the Company and its
subsidiaries and affiliates (collectively, the "Firm") in order to attract,
retain and motivate such personnel and to further align the interests of such
personnel with those of the stockholders of the Company.

         2. TYPES OF AWARDS. Awards under the Plan may be in the form of (a)
options to purchase shares of the Company's common stock, $0.01 par value
("Common Stock"), including options intended to qualify as "incentive stock
options" ("ISOs") within the meaning of Section 422 of the Internal Revenue Code
of 1986, as amended (the "Code") and options which do not qualify as ISOs
("NQSOs"), (b) restricted shares of Common Stock, (c) restricted stock units
tied to shares of Common Stock, and (d) other equity-based awards related to
shares of Common Stock, including stock appreciation rights and dividend
equivalents, which the Committee determines to be consistent with the purposes
of the Plan.

         3. ADMINISTRATION.

                  (a) COMMITTEE. The Plan shall be administered by the Board of
Directors of the Company (the "Board") or a committee or subcommittee thereof
(the "Committee") appointed by the Board. If a Committee is appointed, then,
unless the Board determines otherwise, its members shall consist solely of
individuals who qualify as "non-employee directors" under Rule 16b-3 promulgated
under Section 16 of the Securities Exchange Act of 1934, as amended (the
"Exchange Act") and as "outside directors" under Section 162(m) of the Code. If
for any reason the Committee does not satisfy the "non-employee director"
requirements of Rule 16b-3 or the "outside director" requirements of Section
162(m) of the Code, such non-compliance shall not affect the validity of the
awards, interpretations or other actions of the Committee. Notwithstanding
anything herein to the contrary, the Plan shall be administered solely by the
Board with respect to grants made to non-employee directors of the Company. To
the extent that the Plan is administered by the Board, the Board shall have all
the authority and responsibility granted to the Committee herein.

                  (b) AUTHORITY OF COMMITTEE. Subject to the limitations of the
Plan, the Committee, acting in its sole and absolute discretion, shall have full
power and authority to (i) select the persons to whom awards shall be made under
the Plan, (ii) make awards to such persons and prescribe the terms and
conditions of such awards, (iii) construe, interpret and apply the provisions of
the Plan and of any agreement or other document evidencing an award made under
the Plan, (iv) prescribe, amend and rescind rules and regulations relating to
the Plan, including rules governing its own operations, (v) correct any defect,
supply any omission and reconcile any inconsistency in the Plan, (vi) amend any
outstanding award in any respect, including, without limitation, to accelerate
the time or times at which the award becomes
<PAGE>

vested, unrestricted or may be exercised, (vii) carry out any responsibility or
duty specifically reserved to the Committee under the Plan, and (viii) make any
and all determinations and interpretations and take such other actions as may be
necessary or desirable in order to carry out the provisions, intent and purposes
of the Plan. A majority of the members of the Committee shall constitute a
quorum. The Committee may act by the vote of a majority of its members present
at a meeting at which there is a quorum or by unanimous written consent.

                  (c) INDEMNIFICATION. The Company shall indemnify and hold
harmless each member of the Committee and any employee or director of the Firm
to whom any duty or power relating to the administration or interpretation of
the Plan is delegated from and against any loss, cost, liability (including any
sum paid in settlement of a claim with the approval of the Board), damage and
expense (including legal and other expenses incident thereto) arising out of or
incurred in connection with the Plan, unless and except to the extent
attributable to such person's fraud or wilful misconduct.

         4. SHARE LIMITATIONS. Subject to adjustment pursuant to Section 13
below, the maximum number of shares of Common Stock that may be issued under the
Plan is 4,687,500. For this purpose, the following shares shall be deemed not to
have been issued and shall be deemed to remain available for issuance: (a)
shares covered by the unexercised portion of an option or stock appreciation
right that terminates, expires or is canceled, (b) shares of restricted stock
that are forfeited or repurchased in accordance with the terms of the award, (c)
shares represented by restricted stock units or other-equity based awards that
are forfeited, canceled or otherwise terminated, and (d) shares that are
withheld in order to pay the purchase price for shares covered by any award or
to satisfy the tax withholding obligations associated with any award under the
Plan. Shares of Common Stock available for issuance under the Plan may be
authorized and unissued, held by the Company in its treasury or otherwise
acquired for purposes of the Plan. No fractional shares of Common Stock shall be
issued under the Plan. The maximum number of shares of Common Stock with respect
to which awards (including options and stock appreciation rights) may be granted
under the Plan to any employee in any calendar year shall be 500,000 shares.

         5. ELIGIBILITY. Awards under the Plan may be made to such officers,
directors, employees (including prospective employees), consultants and other
individuals who may perform services for the Firm, as the Committee may select.
In making awards under the Plan, the Committee shall give consideration to the
functions and responsibilities of a potential recipient, the potential
recipient's previous and/or expected future contributions to the business of the
Firm and such other factors as the Committee deems relevant under the
circumstances.

         6. STOCK OPTIONS. Subject to the provisions of the Plan, the Committee
may grant options to eligible personnel upon such terms and conditions as the
Committee deems appropriate. The terms and conditions of any option shall be
evidenced by a written option agreement or other instrument approved for this
purpose by the Committee.


                                      -2-
<PAGE>

                  (a) EXERCISE PRICE. The exercise price per share of Common
Stock covered by an option granted under the Plan may not be less than the fair
market value per share on the date of grant (or, in the case of an ISO granted
to an optionee who, at the time the option is granted, owns stock possessing
more than 10% of the total combined voting power of all classes of stock of the
Company or a "subsidiary" of the Company within the meaning of Section 424 of
the Code, 110% of fair market value).

                  (b) OPTION TERM. No option granted under the Plan may be
exercisable (if at all) more than ten years after the date the option is granted
(or, in the case of an ISO granted to a ten percent stockholder described in
Section 422 of the Code, five years).

                  (c) VESTING AND EXERCISE OF OPTIONS. The Committee may
establish such vesting and other conditions and restrictions on the exercise of
an option and/or upon the issuance of Common Stock in connection with the
exercise of an option as it deems appropriate. Subject to satisfaction of
applicable withholding requirements, once vested and exercisable, an option may
be exercised by transmitting to the Company (i) a notice specifying the number
of shares to be purchased and (ii) payment of the exercise price. The exercise
price of an option may be paid in cash and/or such other form of payment as the
Company may permit.

                  (d) RIGHTS AS A STOCKHOLDER. No shares of Common Stock shall
be issued in respect of the exercise of an option until full payment of the
exercise price and the applicable tax withholding obligation with respect to
such exercise has been made or provided for. The holder of an option shall have
no rights as a stockholder with respect to any shares covered by an option until
the date such shares are issued. Except as otherwise provided herein, no
adjustments shall be made for dividend distributions or other rights for which
the record date is prior to the date such shares are issued.

                  (e) BUY OUT AND SETTLEMENT. The Committee, on behalf of the
Company, may at any time offer to buy out any outstanding option on such terms
and conditions as the Committee shall establish.

         7. RESTRICTED STOCK AND RESTRICTED STOCK UNITS. Subject to the
provisions of the Plan, the Committee may award restricted shares of Common
Stock and/or restricted stock units tied to shares of Common Stock to eligible
personnel upon such terms and subject to such conditions and restrictions as the
Committee deems appropriate. The terms and conditions of any restricted stock or
restricted stock unit award shall be evidenced by a written agreement or other
instrument approved for this purpose by the Committee.

                  (a) PURCHASE PRICE. The purchase price payable for shares of
restricted stock and for shares issued pursuant to the settlement of a
restricted stock unit may be as low as zero, provided, however, that to the
extent required by applicable law, the purchase price per share shall be no less
than the par value of a share of Common Stock.


                                      -3-
<PAGE>

                  (b) RESTRICTIONS AND VESTING. The Committee may establish such
conditions and restrictions on the vesting of restricted stock and restricted
stock units and on the issuance of shares of restricted stock as it deems
appropriate, including, without limitation, conditions and restrictions based
upon continued service, the attainment of specified performance goals and/or
other factors and criteria deemed relevant for this purpose.

                  (c) RIGHTS AS A STOCKHOLDER. The holder of restricted stock
units awarded under the Plan shall have only the rights of a general unsecured
creditor of the Company and shall have no rights as a stockholder with respect
to the shares of Common Stock referenced by such units until such shares are
issued in the name of the holder following the satisfaction or expiration of the
vesting and other conditions and restrictions applicable to such units. The
recipient of restricted stock shall have the rights of a stockholder with
respect to the restricted stock, subject to any restrictions and conditions as
the Committee may impose.

                  (d) STOCK CERTIFICATES FOR RESTRICTED STOCK. Unless the
Committee elects otherwise, shares of restricted stock shall be evidenced by
book entries on the Company's stock transfer records pending the expiration of
restrictions thereon. If a stock certificate for shares of restricted stock is
issued, it shall bear an appropriate legend to reflect the nature of the
restrictions applicable to the shares represented by the certificate, and the
Committee may require that any or all such stock certificates be held in custody
by the Company until the applicable restrictions have lapsed. The Committee may
establish such other conditions as it deems appropriate in connection with the
issuance of certificates for shares of restricted stock, including, without
limitation, a requirement that the grantee deliver a duly signed stock power,
endorsed in blank, for the shares covered by the award.

                  (e) LAPSE OF RESTRICTIONS. If and when the vesting conditions
and other restrictions applicable to a restricted stock or restricted stock unit
award are satisfied or expire, a certificate for the shares covered or
referenced by the award, to the extent vested and free of restrictions, shall be
delivered to the holder. All legends shall be removed from said certificates at
the time of delivery except as otherwise required by applicable law.

         8. OTHER EQUITY-BASED AWARDS. The Committee may grant other types of
equity-based awards, including, without limitation, the grant or offer for sale
of unrestricted shares of Common Stock and/or the grant of stock appreciation
rights or dividend equivalents, in such amounts and subject to such terms and
conditions as the Committee shall determine. Such awards may entail the transfer
of actual shares of Common Stock to Plan participants, or payment in cash or
otherwise of amounts based on the value of shares of Common Stock and may
include, without limitation, awards designed to comply with or take advantage of
the applicable local laws or jurisdictions other than the United States.

         9. TERMINATION OF EMPLOYMENT OR SERVICE. Unless otherwise determined by
the Committee at grant or, if no rights of the recipient are thereby reduced,
thereafter, and subject to earlier termination


                                      -4-
<PAGE>

in accordance with the provisions hereof, the following rules apply with regard
to awards held by a recipient at the time of his or her termination of
employment or other service with the Firm:

                  (a) STOCK OPTIONS AND STOCK APPRECIATION RIGHTS.

                           (i) TERMINATION BY REASON OF DEATH. If a
participant's employment or service terminates by reason of his or her death,
then any option or stock appreciation right held by the deceased participant
shall thereupon become fully vested and may be exercised by the deceased
participant's beneficiary at any time within one year from the date of death but
in no event after expiration of the stated term and, to the extent not exercised
within such time period, will be canceled.

                           (ii) TERMINATION BY REASON OF DISABILITY. If a
participant's employment or service is terminated by the Firm due to his or her
Disability (as hereinafter defined), then any option or stock appreciation right
held by the participant, to the extent exercisable on the date his or her
employment or service terminates, may be exercised by the participant at any
time within one year from the date his or her employment or service terminates
but in no event after expiration of the stated term, and, to the extent not
exercised within such time period, will be canceled. If the participant dies
during such one-year period, then the deceased participant's beneficiary may
exercise the option or stock appreciation right, to the extent exercisable by
the deceased participant immediately prior to his or her death, for a period of
one year following the date of death but in no event after expiration of the
stated term. "Disability" means a participant's absence from employment for at
least 180 days in any twelve month period as a result of his or her incapacity
due to physical or mental illness, as determined by the Committee.

                           (iii) TERMINATION FOR CAUSE. If a participant's
employment or service is terminated by the Firm for Cause (as hereinafter
defined) or if, at the time of a participant's termination, a ground for
termination for Cause exists, then, notwithstanding anything to the contrary
contained herein, any option or stock appreciation right held by the participant
(whether or not otherwise vested) shall immediately terminate and cease to be
exercisable. "Cause" means (A) in the case where there is no employment or
consulting agreement between the participant and the Firm or where such an
agreement exists but does not define "Cause" (or words of like import), a
termination classified by the Firm as a termination due to the participant's
dishonesty, fraud, insubordination, willful misconduct, refusal to perform
services or materially unsatisfactory performance of his or her duties, or (B)
in the case where there is an employment or consulting agreement between the
participant and the Firm, a termination that is or would be deemed for "cause"
(or words of like import) under such agreement.

                           (iv) OTHER TERMINATION. If a participant's employment
or service terminates for any reason (other than death, Disability or Cause or
at a time when Cause exists) or no reason, then any option or stock appreciation
right held by the participant, to the extent not then exercisable, shall
thereupon terminate. Any option or stock appreciation right held by the
participant which is exercisable at the time of such termination of employment
or service shall remain exercisable during the thirty-day period following


                                      -5-
<PAGE>

such termination of employment or service or, if sooner, until the expiration of
the stated term of the option or stock appreciation right and, to the extent not
exercised within such period, shall thereupon terminate.

                  (b) RESTRICTED STOCK, RESTRICTED STOCK UNITS AND OTHER-EQUITY
BASED AWARDS. Unless otherwise determined by the Committee, upon the termination
of a recipient's employment or service for any reason (including, without
limitation, death or Disability) or no reason, any shares of restricted stock,
restricted stock units or other equity-based awards (other than stock options
and stock appreciation rights covered by Section 9(a) hereof) which have not yet
become fully vested shall be forfeited, and any certificate therefor or book
entry with respect thereto or other evidence thereof shall be canceled.

         10. FAIR MARKET VALUE. For purposes of the Plan, the fair market value
of a share of Common Stock, as of any date, shall be determined in good faith by
the Board in a uniform and consistent manner.

         11. NON-TRANSFERABILITY. No stock option or stock appreciation right
granted under the Plan shall be transferable by the recipient other than upon
the recipient's death to a beneficiary designated by the recipient in a manner
acceptable to the Committee, or, if no designated beneficiary shall survive the
recipient, pursuant to the recipient's will or by the laws of descent and
distribution. All stock options and stock appreciation rights shall be
exercisable during the recipient's lifetime only by the recipient. Shares of
restricted stock and restricted stock units may not be transferred prior to the
date on which shares are issued or, if later, the date on which such shares have
vested and are free of any applicable restriction imposed hereunder. Except as
otherwise specifically provided by law or the provisions hereof or the
applicable award agreement or instrument, no award received under the Plan may
be transferred in any manner, and any attempt to transfer any such award shall
be void, and no such award shall in any manner be liable for or subject to the
debts, contracts, liabilities, engagements or torts of any person who shall be
entitled to such award, nor shall it be subject to attachment or legal process
for or against such person. Notwithstanding the foregoing, the Committee may
determine at the time of grant or thereafter that an NQSO is transferable in
whole or part to such persons, under such circumstances, and subject to such
conditions as the Committee may prescribe.

         12. OTHER CONDITIONS. The Committee may impose such other conditions
with respect to the grant of awards or the issuance of shares of Common Stock
pursuant to the Plan, including, without limitation, conditions relating to the
application of federal or state securities laws or exchange requirements as it
deems necessary or advisable.

         13. CAPITAL CHANGES; CHANGE IN CONTROL; MERGER.

                  (a) ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. The aggregate
number and class of shares for which awards may be granted under the Plan, the
maximum number of shares that may be covered by individual awards in any year,
the number and class of shares covered by each outstanding award and, if
applicable, the exercise price per share shall all be adjusted proportionately
or as otherwise


                                      -6-
<PAGE>

appropriate to reflect any increase or decrease in the number of issued shares
of Common Stock resulting from a split-up or consolidation of shares or any like
capital adjustment, or the payment of any stock dividend, and/or to reflect a
change in the character or class of shares covered by the Plan arising from a
readjustment or recapitalization of the Company's capital stock.

                  (b) CHANGE IN CONTROL. The Committee may provide in any award
agreement for the effect on the award of a "change in control" of the Company or
any of its subsidiaries or affiliates (as such term is defined by the Committee
in any such award agreement), including, without limitation, the acceleration of
the exercisability of, or the lapse of restrictions or deemed satisfaction of
goals with respect to, any outstanding awards.

                  (c) MERGER; CONSOLIDATION. Unless otherwise provided in the
applicable award agreement, in the event of a merger, consolidation, mandatory
share exchange or other similar business combination of the Company with or into
any other entity ("Successor Entity") or any transaction in which another person
or entity acquires all the issued and outstanding Common Stock, or all or
substantially all the assets of the Company, outstanding awards may be assumed
or an equivalent award may be substituted by the Successor Entity or a parent or
subsidiary of the Successor Entity.

                  (d) FRACTIONAL SHARES. In the event of any adjustment in the
number of shares covered by any option pursuant to the provisions hereof, any
fractional shares resulting from such adjustment shall be disregarded, and each
such option shall cover only the number of full shares resulting from the
adjustment.

                  (e) DETERMINATIONS FINAL. All adjustments under this Section
13 shall be made by the Committee, and its determination as to what adjustments
shall be made, and the extent thereof, shall be final, binding and conclusive.

         14. TAX WITHHOLDING. As a condition to the exercise of any award or the
delivery of any shares of Common Stock pursuant to any award or the lapse of
restrictions on any award, or in connection with any other event that gives rise
to a federal or other governmental tax withholding obligation on the part of the
Firm relating to an award, (a) the Firm may deduct or withhold (or cause to be
deducted or withheld) from any payment or distribution to a grantee whether or
not pursuant to the Plan or (b) the Firm shall be entitled to require that the
grantee remit cash to the Firm (through payroll deduction or otherwise), in each
case in an amount sufficient in the opinion of the Company to satisfy such
withholding obligation. If the event giving rise to the withholding obligation
involves a transfer of shares of Common Stock, then, unless the applicable award
agreement provides otherwise, at the discretion of the Committee, the grantee
may satisfy the withholding obligation described under this Section 14 by
electing to have the Company withhold shares of Common Stock (which withholding
will be at a rate not in excess of the statutory minimum rate) or by tendering
previously owned shares of Common Stock, in each case having a fair market value
equal


                                      -7-
<PAGE>

to the amount of tax to be withheld (or by any other mechanism as may be
required or appropriate to conform with local tax and other rules).

         15. AMENDMENT AND TERMINATION. The Board may amend or terminate the
Plan, provided, however, that no such action may affect adversely the accrued
rights of the holder of any outstanding award without the consent of the holder.
Except as otherwise provided in Section 13, any amendment which would increase
the number of shares of Common Stock for which awards may be granted under the
Plan (in the aggregate or on an individual basis) or modify the class of
individuals eligible to receive awards under the Plan shall be subject to the
approval of the Company's stockholders. The Committee may amend the terms of any
agreement or certificate made or issued hereunder at any time and from time to
time, provided, however, that any amendment which would adversely affect the
accrued rights of the holder may not be made without his or her consent.

         16. NO RIGHTS CONFERRED. Nothing contained herein shall be deemed to
give any individual any right to receive an award under the Plan or to be
retained in the employ or service of the Firm.

         17. DECISIONS AND DETERMINATIONS TO BE FINAL. All decisions and
determinations made by the Board pursuant to the provisions hereof and, except
to the extent rights or powers under the Plan are reserved specifically to the
discretion of the Board, all decisions and determinations of the Committee shall
be final, binding and conclusive.

         18. GOVERNING LAW. All rights and obligations under the Plan and each
award agreement or instrument shall be governed by and construed in accordance
with the laws of the State of New York, without regard to its principles of
conflict of laws.

         19. TERM OF THE PLAN. The Plan shall become effective on the date of
its adoption by the Board. Unless sooner terminated by the Board, the Plan shall
terminate on the tenth anniversary of the date of its adoption by the Board. The
rights of any person with respect to an award made under the Plan that is
outstanding at the time of the termination of the Plan shall not be affected
solely by reason of the termination of the Plan and shall continue in accordance
with the terms of the award (as then in effect or thereafter amended) and the
Plan.

                               LABRANCHE & CO INC.
                              ANNUAL INCENTIVE PLAN

      1.  PURPOSE. The purpose of the LaBranche & Co Inc. Annual Incentive Plan
(the "Plan") is to enable LaBranche & Co Inc. (the "Company") and its
subsidiaries and affiliates (collectively with the Company, the "Firm") to
attract, motivate and retain employees by allowing them to participate in an
annual profit-based compensation pool.

      2.  ADMINISTRATION.

          (a) COMMITTEE. The Plan shall be administered by a committee (the
"Committee") appointed by the Board of Directors of the Company (the "Board")
whose members shall serve at the pleasure of the Board. Notwithstanding the
foregoing, the Board may, in its sole discretion, at any time and from time to
time, resolve to administer the Plan. In such event, the Board shall have all
the authority and responsibility granted to the Committee herein.

          (b) AUTHORITY OF COMMITTEE. Subject to the limitations of the Plan,
the Committee, acting in its sole and absolute discretion, shall have full power
and authority to (i) select those employees (in addition to the managing
directors of the Firm) who shall participate in the Plan for any fiscal year of
the Company, (ii) prescribe the terms and conditions of bonus awards under the
Plan, (iii) construe, interpret and apply the provisions of the Plan, (iv)
prescribe, amend and rescind rules and regulations relating to the Plan,
including rules governing its own operations, (v) correct any defect, supply any
omission and reconcile any inconsistency in the Plan, (vi) carry out any
responsibility or duty specifically reserved to the Committee under the Plan,
and (vii) make any and all determinations and interpretations and take such
other actions as may be necessary or desirable in order to carry out the
provisions, intent and purposes of the Plan. The determination of the Committee
on all matters relating to the Plan shall be final, binding and conclusive. The
Committee may allocate among its members and delegate to any person who is not a
member of the Committee any of its administrative responsibilities.

          (c) INDEMNIFICATION. The Company shall indemnify and hold harmless
each member of the Committee and any employee or director of the Firm to whom
any duty or power relating to the administration or interpretation of the Plan
is delegated from and against any loss, cost, liability (including any sum paid
in settlement of a claim with the approval of the Board), damage and expense
(including legal and other expenses incident thereto) arising out of or incurred
in connection with the Plan, unless and except to the extent attributable to
such person's fraud or wilful misconduct.

      3.  PARTICIPATION. Participation in the Plan is limited to (a) managing
directors of the Firm and (b) such other employees of the Firm as the Committee,
acting in its sole discretion, may select.

<PAGE>

      4.  COMPENSATION POOL.

          (a) ESTABLISHMENT AND ALLOCATION. The Firm will set aside thirty
percent (30%) of its Pre-Tax Income (as defined below), or such lower
percentage as the Committee may determine, for each fiscal year for the
payment of incentive bonuses to Plan participants. The amount set aside for
any fiscal year (the "Compensation Pool") shall be reduced by the amount of
compensation expense charged to the Company for such fiscal year attributable
to the Company's award to its employees of restricted stock units with
respect to shares of its common stock in connection with the initial offering
of its shares to the public. The Compensation Pool will be allocated among
the Plan participants in such amounts or percentages as the Committee, acting
in its sole discretion, shall determine, provided that not more than
twenty-five percent (25%) of the Compensation Pool may be allocated to any
participant for any fiscal year. In allocating the Compensation Pool for any
fiscal year, the Committee may take into account such factors and
considerations as it deems appropriate in any individual case. "Pre-Tax
Income" for any fiscal year shall mean the Company's "income before provision
for income taxes" for such fiscal year, as reported on the Company's audited
financial statements.

          (b) TERMINATION OF EMPLOYMENT. If a participant's employment with
the Firm terminates for any reason before the end of a fiscal year of the
Company, the Committee shall have the discretion to determine whether (i)
such participant's share of the Compensation Pool shall be forfeited, (ii)
such participant's share of the Compensation Pool shall be reduced on a
pro-rata basis to reflect the portion of such fiscal year during which the
participant was employed by the Firm or (iii) to make such other arrangements
as the Committee deems appropriate in connection with the termination of such
participant's employment. The Committee, acting in its sole discretion, shall
determine whether and the manner in which the percentage of the Compensation
Pool for any fiscal year which is forfeited or otherwise not applied will be
allocated to participants and/or otherwise utilized for the benefit of the
Firm.

      5.  PAYMENT OF BONUS AMOUNT; DEFERRAL. A participant's share of the
Compensation Pool for any year will be payable by the Firm as soon as
practicable following the end of the fiscal year, in such manner and upon
such terms and conditions as the Committee may determine. Subject to such
terms and conditions as may be imposed by the Committee, each participant may
be permitted or required to defer receipt of part or all of any payments
otherwise due under the Plan.

      6.  GENERAL PROVISIONS.

          (a) AMENDMENT; TERMINATION. The Board reserves the right at any time
and from time to time to modify, alter, amend, suspend, discontinue or terminate
the Plan in any respect whatsoever, provided that no such action may reduce the
amount or jeopardize the payment of any previously declared bonus that is then
owed by the Firm to a participant without such participant's consent.

          (b) NONASSIGNABILITY; DESIGNATION OF BENEFICIARIES. Except as
otherwise specifically provided in this Section 6(a) with respect to the
disposition of a deceased participant's interest in the Plan (if any), no rights
of any participant or beneficiary under the Plan may be transferred, assigned or
otherwise disposed of, and any attempted transfer, assignment or other
disposition shall be void. A participant may designate a beneficiary who will be
entitled to receive

                                       2
<PAGE>


the amount, if any, that may be payable under the Plan as a result of the
participant's death by filing a written beneficiary designation with the Company
in a manner that is acceptable to the Committee. A beneficiary designation may
be replaced or revoked by filing a new beneficiary designation form in the same
manner. If a deceased participant is not survived by a designated beneficiary,
then any amount payable under the Plan on account of the deceased participant's
death will be paid to his or her estate for disposition in accordance with his
or her will or, if applicable, the laws of descent and distribution.

          (c) PLAN CREATES NO EMPLOYMENT RIGHTS. Nothing in the Plan shall
confer upon any participant the right to continue in the employ or other service
of the Firm or affect the right of the Firm to terminate such employment or
other service at any time.

          (d) ARBITRATION. Any dispute, controversy or claim between the Firm
and any participant arising out of or relating to or concerning the provisions
of the Plan shall be finally settled by arbitration in New York City before, and
in accordance with the rules then obtaining of, the New York Stock Exchange,
Inc. ("NYSE") or, if the NYSE declines to arbitrate the matter, the American
Arbitration Association (the "AAA") in accordance with the commercial
arbitration rules of the AAA. Prior to arbitration, all claims asserted by any
participant must first be submitted to the Committee.

          (e) GOVERNING LAW. All rights and obligations under the Plan shall be
governed by and construed in accordance with the laws of the state of New York,
without regard to principles of conflict of laws.

          (f) TAX WITHHOLDING. All bonus payments under the Plan will be subject
to applicable tax withholding requirements.

          (g) RIGHT OF OFFSET. The Firm shall have the right to offset, against
the obligation to pay amounts to any participant under the Plan, any outstanding
amounts such participant then owes to the Firm and any amounts the Firm
otherwise deems appropriate pursuant to any tax equalization policy or
agreement.

[Name]
[Address]

Dear _______:

         We are pleased to offer you continued employment as a Managing Director
of LaBranche & Co., a New York limited partnership (the "Company"), or one or
more of its subsidiaries or affiliates (individually and collectively, the
"Firm") upon the terms and conditions set forth herein.

         1. You shall be employed by the Firm, subject to the terms and
conditions of this Agreement, for the period commencing on the consummation of
the initial public offering of the equity securities of LaBranche & Co Inc. (the
"Commencement Date ") and, unless terminated earlier in accordance herewith,
ending on __________, 200 _ (the "Initial Employment Period") [3/5 years?].
After the Initial Employment Period (unless otherwise agreed by you and the Firm
in writing), there shall be no set term of employment. For purposes of this
Agreement, the term "Employment Period" means the period commencing on the
Commencement Date and ending on the date on which your employment by the Firm
terminates, and includes the Initial Employment Period.

         2. During the Employment Period, you shall: (i) have such duties and
responsibilities as are assigned by the Firm from time to time; (ii) devote your
entire business time exclusively to the faithful, diligent and competent
performance of your duties and responsibilities; and (iii) be subject to the

in connection with its securities business. You shall refrain from engaging in
any aspect of the securities business except on behalf of the Firm without the
prior approval of the New York Stock Exchange, Inc. (the "NYSE"). You shall be
subject to all terms and conditions of employment generally applicable to
comparable employees of the Firm, as established by the Firm from time to time.

         3. [The Firm shall pay you an initial base salary that is not less than
your base salary in effect on the date hereof.] Such salary shall be paid in
accordance with the Firm's normal payroll practices and shall be subject to
review by the Firm from time to time. During the

<PAGE>

Employment Period, you shall be entitled to receive an annual bonus under the
Firm's Annual Incentive Plan in accordance with the terms thereof.

         4. Subject to your satisfaction of any applicable eligibility
requirements, you shall be entitled to participate, in accordance with the terms
thereof, in all employee benefit plans and programs generally provided by the
Firm to its senior executives, including any health, disability, insurance or
other benefit plans or programs now existing or hereafter adopted.

         5. You shall be reimbursed by the Firm for all reasonable business
expenses incurred by you in the performance of your duties hereunder for which
you submit expense statements or vouchers and such other supporting information
and substantiation as the Firm customarily requires of its employees.

         6. You or the Firm may terminate your employment at any time for any
reason, or for no reason, by giving not less than ninety (90) days' prior
written notice of termination; provided, however, that the Firm may elect to
place you on paid leave for all or any part of such 90-day period; and provided
further that no advance notice need be given by the Firm to you in connection
with a termination of your employment for Cause or on account of Disability.
"Cause" means: (i) your breach of this Agreement, the Agreement Relating to
Noncompetition and Other Covenants dated as of the date hereof between you and
the Company (the "Noncompetition Agreement"), the Pledge Agreement dated as of
the date hereof between you and the Company, the Stockholders' Agreement dated
as of the date hereof among LaBranche & Co, Inc. and the individuals listed on
Schedules I and II thereto or any other written agreement between you and the
Firm; (ii) your violation of any Firm policy (including in respect of hedging or
confidential information) as in effect from time to time; (iii) your conviction
of, or pleading NOLO CONTENDERE to, a crime involving moral turpitude or a
felony; or (iv) your becoming subject to any "statutory disqualification" within
the meaning of Section 3(a)(39) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act "). "Disability" means your absence from employment
for at least 180 days in any 12-month period as a result of your incapacity due
to mental or physical illness, as determined by the Firm.

         7. You shall comply with all laws applicable to the securities business
of the Firm and with all rules and regulations of the Securities and Exchange
Commission, the NYSE (and any other securities exchange of which the Firm is a
member), and any regulatory authority of a state in which the Firm is registered
as a broker-dealer. You shall provide the Firm with such written information as
may be necessary for the Firm to complete accurately all forms required by the
rules and regulations of the NYSE, the Securities and Exchange Commission or any
other regulatory organization to which the Firm is subject. You shall duly and
accurately file all required income tax returns and agree to retain Arthur
Andersen LLP (or such other nationally recognized firm of independent certified
public accountants as the Firm shall designate from time to time) to prepare
your federal, state and local personal income tax returns for all taxable
periods during the Employment Period. You shall acknowledge that you are an
agent and/or representative of the Firm in registration applications filed with
appropriate regulatory authorities, and you shall be subject to the applicable
approved person rules of the NYSE. You acknowledge that you are not subject to
any "statutory disqualification" within the meaning of Section 3(a)(39) of the
Exchange Act.


                                       2

         8. The Firm may withhold from any and all amounts payable hereunder
such federal, state and local taxes as may be required to be withheld pursuant
to any applicable law or regulation.

         9. Any dispute, controversy or claim between you and the Firm arising
out of or relating to or concerning the provisions of this Agreement, your
employment with the Firm or otherwise concerning any rights, obligations or
other aspects of your employment relationship in respect of the Firm, shall be
finally resolved in accordance with the provisions of Sections 9, 10 and 11 of
the Noncompetition Agreement. Without limiting the foregoing, you acknowledge
that a violation on your part of this Agreement would cause irreparable damage
to the Firm. Accordingly, you agree that the Firm shall be entitled to
injunctive relief for any actual or threatened violation of this Agreement in
addition to any other remedies it may have.

         10. This agreement shall be governed by and construed in accordance
with the laws of the State of New York, without regard to principles of conflict
of laws.

         11. This Agreement shall supersede any and all prior understandings and
agreements between you and the Firm, whether written or oral, relating to the
subject matter hereof. Notices hereunder shall be delivered to the Firm at its
principal executive office directed to the attention of the Company's Chief
Executive Officer, and to you at your last address appearing in the Firm's
employment records.

         12. You may not, directly or indirectly (including by operation of
law), assign your rights or obligations hereunder. The Company may at any time
and from time to time assign its rights and obligations hereunder, including,
without limitation, to any of its subsidiaries or affiliates (and have such
rights and obligations reassigned to it or to any other subsidiary or
affiliate). This Agreement shall inure to the benefit of and be binding upon the
Firm and its assigns. This Agreement may not be amended or modified other than
by a written agreement executed by you and the Company or its successors, nor
may any provision hereof be waived other than by a writing executed by you or
the Company or its successors.

         13. If any provision of this Agreement is finally held to be invalid,
illegal or unenforceable (whether in whole or in part), such provision shall be
deemed modified to the extent, but only to the extent, of such invalidity,
illegality or unenforceability and the remaining provisions shall not be
affected thereby. Except as expressly provided herein, this Agreement shall not
confer on any person other than you and the Firm any rights or remedies
hereunder.

         Please confirm your acceptance and agreement to the terms and
conditions hereof by signing and returning the enclosed duplicate of this letter
which shall thereupon constitute an agreement between you and the Company, on

                                       subsidiaries and affiliates)

                              AGREEMENT RELATING TO
                       NONCOMPETITION AND OTHER COVENANTS


         This AGREEMENT, dated as of June ___, 1999 (this "AGREEMENT"), is by
and between LaBranche & Co Inc., a Delaware corporation (the "COMPANY"), and the
individual whose name appears at the end of this Agreement ("COVENANTOR").

         WHEREAS, in connection with Covenantor's participation in the Exchange
Agreement, dated as of June __, 1999, by and among the Company, LaB Investing
Co. L.L.C., a New York limited liability company ("INVESTING"), and the members
of Investing listed on Schedule A thereto (the "EXCHANGE AGREEMENT"), Covenantor
has agreed to certain obligations, inter alia, to keep information concerning
the Company, LaBranche & Co., a New York limited partnership ("LABRANCHE LP"),
and Investing (the Company, LaBranche LP and Investing being hereinafter
referred to collectively or individually, as applicable, as the "COMPANY
GROUP"), confidential, not to engage in competitive activities, not to solicit
listed companies (as defined below) or the Company Group's employees and to
cooperate with the Company Group in maintaining certain relationships following
the termination of Covenantor's employment with the Company Group.

         NOW, THEREFORE, in consideration of the premises contained herein and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, Covenantor and the Company agree as follows:

         1. CONFIDENTIAL INFORMATION. In the course of involvement in the
Company Group's activities or otherwise, Covenantor has obtained or may obtain
confidential information concerning the Company Group's businesses, strategies,
operations, financial affairs, organizational and personnel matters (including
information regarding any aspect of Covenantor's tenure as an officer, managing
director, partner, consultant or employee of the Company Group or of the
termination of such office, position, partnership, arrangement or employment),
policies, procedures and other non-public matters, or concerning those of third
parties. Such information ("CONFIDENTIAL INFORMATION") may have been or be
provided in written or electronic form or orally. In consideration of, and as a
condition to, continued access to Confidential Information, and without
prejudice to or limitation of any other confidentiality obligations imposed by
agreement or by law, Covenantor hereby undertakes to use and protect
Confidential Information in accordance with any restrictions placed on its use
or disclosure. Without limiting the foregoing, except as authorized by the
Company Group or as required by law, Covenantor may not disclose or allow
disclosure of any Confidential Information, or of any information derived
therefrom, in whatever form, to any person unless such person is a director,
officer, partner, employee, attorney or agent of the Company Group and, in
Covenantor's reasonable good faith judgment, has a need to know the Confidential
Information or information derived therefrom in furtherance of the business of
the Company Group. The foregoing obligations will survive, and remain binding
and enforceable notwithstanding any

<PAGE>

termination of Covenantor's employment with the Company Group and any settlement
of the financial rights and obligations arising from Covenantor's employment
with the Company Group. Without limiting the foregoing, the existence of, and
any information concerning, any dispute between Covenantor and the Company Group
shall constitute Confidential Information except that Covenantor may disclose
information concerning such dispute to the arbitrator or court that is
considering such dispute, or to Covenantor's legal counsel (provided that such
counsel agrees not to disclose any such information other than as necessary to
the prosecution or defense of the dispute).

         2. NONCOMPETITION. (a) In view of Covenantor's importance to the
Company Group, Covenantor hereby agrees that the Company Group would likely
suffer significant harm from Covenantor's competing with the Company Group
during the Restricted Period. Accordingly, Covenantor hereby agrees that
Covenantor will not, without the written consent of the Company Group, during
the Restricted Period:

                  (1) form, or acquire a 5% or greater equity ownership, voting
         or profit participation interest in, any Competitive Enterprise; or

                  (2) associate (including, but not limited to, association as
         an officer, employee, partner, director, consultant, agent or advisor)
         with any Competitive Enterprise and in connection with such association
         engage in, or directly or indirectly manage or supervise personnel
         engaged in, any activity

                           (i) which is similar or substantially related to any
                  activity in which Covenantor was engaged, in whole or in part,
                  at the Company Group, or

                           (ii) which calls for the application of the same or
                  similar specialized knowledge or skills as those utilized by
                  Covenantor in Covenantor's activities with the Company Group,
                  at any time during the one-year period immediately prior to
                  the Date of Termination (or, in the case of an action taken
                  during the Covenantor's period of employment with the Company
                  Group, during the one-year period immediately prior to such
                  action), and, in any such case, irrespective of the purpose of
                  the activity or whether the activity is or was in furtherance
                  of advisory, agency, proprietary or fiduciary business of
                  either the Company Group or the Competitive Enterprise.

         (b) For purposes of this Agreement, "RESTRICTED PERIOD" means the
period commencing on the date hereof and ending on the later of (1) the fifth
anniversary of the date of consummation of the initial public offering of the
common stock of the Company (the "IPO DATE") or (2) the first anniversary of
Covenantor's Date of Termination.

         (c) For purposes of this Agreement, a "COMPETITIVE ENTERPRISE" is a
business enterprise that (1) engages in any activity, or (2) owns or controls a
significant interest in any entity that engages in any activity, that, in either
case, competes anywhere with any business activity in


                                       2
<PAGE>

which the Company Group is engaged. The activities covered by the previous
sentence include, without limitation, specialist services and/or securities
brokerage, sales, lending, custody, clearance, settlement or trading.

         (d) For purposes of this Agreement, if Covenantor and the Company Group
are parties to a written agreement relating to Covenantor's employment with the
Company Group on or after the date hereof (the "EMPLOYMENT AGREEMENT"), "DATE OF
TERMINATION" means (i) if Covenantor's employment is terminated by the Company
Group for Cause or on account of Disability, as those terms are defined in the
Employment Agreement, the date of the Company Group's delivery of written notice
of termination to Covenantor, (ii) if Covenantor's employment is terminated by
the Company Group other than for Cause or on account of Disability, the date
that is ninety (90) days after the Company Group's delivery of written notice of
termination to Covenantor, or (iii) if Covenantor's employment is terminated by
Covenantor, the date that is ninety (90) days after Covenantor's delivery of
written notice of termination to the Company Group. If Covenantor and the
Company Group are not parties to an Employment Agreement, "DATE OF TERMINATION"
means the date Covenantor's employment with the Company Group is terminated, for
whatever reason.

         3. NONSOLICITATION OF LISTED COMPANIES (a) Covenantor hereby agrees
that during the Restricted Period, Covenantor will not, in any manner, directly
or indirectly, (1) Solicit a listed company to transact business with a
Competitive Enterprise or to reduce or refrain from doing any business with the
Company Group, or (2) interfere with or damage (or attempt to interfere with or
damage) any relationship between the Company Group and a listed company.

         (b) For purposes of this Agreement, the term "SOLICIT" means any direct
or indirect communication of any kind whatsoever, regardless of by whom
initiated, inviting, advising, encouraging or requesting any person or entity,
in any manner, to take or refrain from taking any action.

         (c) For purposes of this Agreement, the term "LISTED COMPANIES" means
any company (1) for whom the Company Group acts as a specialist, (2) which is
seeking a listing of its stock on the New York Stock Exchange, Inc. (the
"NYSE"), or (3) which is identified by the Company Group as a potential listed
company (whether by new listing, transfer or other means) during the period of
Covenantor's employment by the Company Group.

         4. NONSOLICITATION OF EMPLOYEES. Covenantor hereby agrees that during
the Restricted Period, Covenantor will not, in any manner, directly or
indirectly, Solicit any person who is an employee of the Company Group to resign
from the Company Group or to apply for or accept employment with any Competitive
Enterprise.

         5. TRANSFER OF RELATIONSHIPS WITH LISTED COMPANIES. (a) During the
Coverage Period, Covenantor hereby agrees to take all actions and do all such
things as may be reasonably requested by the Company Group from time to time to
maintain for the Company Group the


                                       3
<PAGE>

business, goodwill, and business relationships with any listed company with whom
Covenantor worked during the term of Covenantor's employment with the Company
Group.

         (b) For purposes of this Agreement, the term "COVERAGE PERIOD" means,
(1) if Covenantor and the Company Group are parties to an Employment Agreement,
the 90-day period beginning on the date on which notice of Covenantor's
termination of employment is delivered to or by the Company Group by or to
Covenantor, or in the case of termination for Cause or on account of Disability,
the 90-day period beginning on the Date of Termination or (2) if Covenantor is
not a party to an Employment Agreement, the 90-day period beginning on the date
Covenantor's employment with the Company Group is terminated, for whatever
reason.

         6. PRIOR NOTICE REQUIRED. Covenantor hereby agrees that prior to
accepting employment with any other person or entity during the Restricted
Period, Covenantor will provide such prospective employer with written notice of
the provisions of this Agreement, with a copy of such notice delivered
simultaneously to the Company Group.

         7. COVENANTS GENERALLY. (a) Covenantor's covenants as set forth in the
preceding paragraphs of this Agreement are from time to time referred to herein
as the "COVENANTS." If any of the Covenants is finally held to be invalid,
illegal or unenforceable (whether in whole or in part), such Covenant shall be
deemed modified to the extent, but only to the extent, of such invalidity,
illegality or unenforceability and the remaining such Covenants shall not be
affected thereby; provided, however, that if any of such Covenants is finally
held to be invalid, illegal or unenforceable because it exceeds the maximum
scope determined to be acceptable to permit such provision to be enforceable,
such Covenant will be deemed to be modified to the minimum extent necessary to
modify such scope in order to make such provision enforceable hereunder.

         (b) Covenantor understands that the provisions of the Covenants may
limit Covenantor's ability to earn a livelihood in a business similar to the
business of the Company Group.

         (c) Covenantor acknowledges that a violation on Covenantor's part of
any of the Covenants would cause irreparable damage to the Company Group.
Accordingly, Covenantor agrees that the Company Group will be entitled to
injunctive relief for any actual or threatened violation of any of the Covenants
in addition to any other remedies it may have.

         8. DAMAGES. (a) Covenantor acknowledges that Covenantor's compliance
with the Covenants is an important factor to the continued success of the
Company Group's operations and its future prospects. Covenantor and the Company
agree that if at any time during the Restricted Period, Covenantor were to
breach any of the Covenants set forth in this Agreement, the damages to the
Company Group would be material, but that the amount of such damages would be
uncertain and not readily ascertainable. Accordingly, Covenantor and the Company
agree that if, prior to the fifth anniversary of the IPO Date, Covenantor
breaches any of such Covenants, as determined by the Board of Directors of the
Company (the "BOARD") in its good faith judgment, the Company Group will be
entitled to receive immediately following such determination and written demand
therefor,



                                       4
<PAGE>

and Covenantor will make, a cash payment as and for liquidated damages (the
"LIQUIDATED DAMAGES") in an amount equal to 75% of the aggregate value of the
common stock of the Company (based on the initial offering price of the common
stock of the Company) and any cash received by Covenantor in the LLC Exchange
(as defined in the Exchange Agreement).

The payment of any amount as Liquidated Damages will not be construed as a
release or waiver by the Company of the right to prevent the continuation of any
such violation of such Covenants in equity or otherwise. In addition, Covenantor
and the Company agree that it would be too speculative to attempt to determine
any amount of liquidated damages that would be applicable following the fifth
anniversary of the IPO Date, and that any damages payable as a result of any
breach following such date shall be determined without regard to this Section 8.

         (b) Covenantor and the Company agree that the Liquidated Damages are
reasonable in proportion to the probable damages likely to be sustained by the
Company Group if Covenantor breaches at any time prior to the fifth anniversary
of the IPO Date any of the Covenants set forth in Sections 2, 3 and 4 hereof,
that the amount of actual damages to be sustained by the Company Group in the
event of such breach is incapable of precise estimation and that such cash
payments are not intended to constitute a penalty or punitive damages for any
purpose.

         (c) Covenantor acknowledges and agrees that Covenantor's payment
obligations in respect of Liquidated Damages under this Agreement will be full
recourse obligations and will be secured pursuant to a Pledge Agreement in
substantially the form set forth as Exhibit A hereto (the "PLEDGE AGREEMENT").
Covenantor further acknowledges and agrees that upon expiration of the Pledge
Agreement, the Company Group will continue to be entitled to all available
remedies for any breach of this Agreement.

         (d) Covenantor acknowledges and agrees that any cash payment of
Liquidated Damages pursuant to this Section 8 shall be in addition to, and not
in lieu of, any forfeitures of awards (required pursuant to the terms of any
such awards) that may be granted to Covenantor in the future under one or more
of the Company Group's compensation and benefit plans.

         9. ARBITRATION. Subject to the provisions of Sections 10 and 11 hereof,
any dispute, controversy or claim between Covenantor and the Company Group
arising out of or relating to or concerning the provisions of this Agreement,
the Pledge Agreement, any agreement between Covenantor and the Company Group
relating to or arising out of Covenantor's employment with the Company Group or
otherwise concerning any rights, obligations or other aspects of Covenantor's
employment relationship in respect of the Company Group ("EMPLOYMENT RELATED
MATTERS"), shall be finally settled by arbitration in New York City before, and
in accordance with the rules then obtaining of, the NYSE or, if the NYSE
declines to arbitrate the matter, the American Arbitration Association (the
"AAA") in accordance with the commercial arbitration rules of the AAA; PROVIDED
HOWEVER, that, in addition to the right to compel arbitration of any dispute or
controversy, the Company Group may bring an action or special proceeding in a
state or federal court of competent jurisdiction sitting in New York City,
whether or not an arbitration proceeding has theretofore been


                                       5
<PAGE>

or is ever initiated, for the purpose of temporarily, preliminarily, or
permanently enforcing the provisions of this Agreement or to enforce an
arbitration award and, for the purposes of this provision, each participant in
this Agreement expressly consents to the jurisdiction of any such court in
respect of any such action and waives to the fullest extent permitted by
applicable law any objection to personal jurisdiction or to the laying of venue
of any such suit, action or proceeding in such court, agrees that proof shall
not be required that monetary damages for breach of the provisions of this
Agreement would be difficult to calculate and that remedies at law would be
inadequate and irrevocably appoints the Secretary of the Company as the
participant's agent for service of process in connection with any such action or
proceeding, who shall promptly advise such participant of any such service of
process.

         10. INJUNCTIVE RELIEF; SUBMISSION TO JURISDICTION. Notwithstanding the
provisions of Section 9, and in addition to its right to submit any dispute or
controversy to arbitration, the Company Group may bring an action or special
proceeding in a state or federal court of competent jurisdiction sitting in the
City of New York, whether or not an arbitration proceeding has theretofore been
or is ever initiated, for the purpose of temporarily, preliminarily, or
permanently enforcing the provisions of the Covenants, the Employment Agreement
(if applicable) or the Pledge Agreement, or to enforce an arbitration award,
and, for the purposes of this Section 10, Covenantor (i) expressly consents to
the application of Section 11 to any such action or proceeding, (ii) agrees that
proof will not be required that monetary damages for breach of the provisions of
the Covenants, the Employment Agreement (if applicable) or the Pledge Agreement
would be difficult to calculate and that remedies at law would be inadequate and
(iii) irrevocably appoints the Secretary of the Company as Covenantor's agent
for service of process in connection with any such action or proceeding, who
shall promptly advise Covenantor of any such service of process.

         11. CHOICE OF FORUM. (a) COVENANTOR AND THE COMPANY HEREBY IRREVOCABLY
SUBMIT TO THE EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED IN
THE CITY OF NEW YORK OVER ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO OR CONCERNING THIS AGREEMENT, THE EMPLOYMENT AGREEMENT (IF
APPLICABLE), THE PLEDGE AGREEMENT, OR ANY EMPLOYMENT RELATED MATTER THAT IS NOT
OTHERWISE ARBITRATED OR RESOLVED ACCORDING TO THE PROVISIONS OF SECTION 9
HEREOF. This includes any suit, action or proceeding to compel arbitration or to
enforce an arbitration award. This also includes any suit, action, or proceeding
arising out of or relating to any post-employment Employment Related Matters.
Covenantor and the Company acknowledge that the forum designated by this Section
11 has a reasonable relation to this Agreement, and to Covenantor's relationship
to the Company Group. Notwithstanding the foregoing, nothing herein shall
preclude the Company Group from bringing any action or proceeding in any other
court for the purpose of enforcing the provisions of Sections 9, 10 or 11.

         (b) The agreement of Covenantor and the Company as to forum is
independent of the law that may be applied in the action, and Covenantor and the
Company agree to such forum even if the forum may under applicable law choose to
apply non-forum law. Covenantor and the


                                       6
<PAGE>

Company hereby waive, to the fullest extent permitted by applicable law, any
objection which Covenantor or the Company now or hereafter may have to personal
jurisdiction or to the laying of venue of any such suit, action or proceeding in
any court referred to in Section 11(a). Covenantor and the Company undertake not
to commence any action arising out of or relating to or concerning this
Agreement in any forum other than a forum described in this Section 11.
Covenantor and the Company agree that, to the fullest extent permitted by
applicable law, a final and non-appealable judgment in any such suit, action or
proceeding in any such court shall be conclusive and binding upon Covenantor and
the Company Group.

         12. CHOICE OF LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES
OF CONFLICT OF LAWS.

         13. MISCELLANEOUS. (a) This Agreement shall not supersede any other
agreement, written or oral, pertaining to the matters covered herein, except to
the extent of any inconsistency between this Agreement and any prior agreement,
in which case this Agreement shall prevail.

         (b) Notices hereunder shall be delivered to the Company Group at its
principal office directed to the attention of the Secretary of the Company, and
to Covenantor at Covenantor's last address appearing in the Company Group's
employment records.

         (c) This Agreement may not be amended or modified, other than by a
written agreement executed by Covenantor and the Company or its successor, nor
may any provision hereof be waived other than by a writing executed by
Covenantor or the Company or its successor; provided, that any waiver, consent,
amendment or modification of any of the provisions of this Agreement will not be
effective against the Company Group without the written consent of the Chief
Executive Officer of the Company or its successor, or such individual's
designee. Covenantor may not, directly or indirectly (including by operation of
law), assign Covenantor's rights or obligations hereunder without the prior
written consent of the Chief Executive Officer of the Company or its successor,
or such individual's designee, and any such assignment by Covenantor in
violation of this Agreement shall be void. This Agreement shall be binding upon
Covenantor's permitted successors and assigns. Without impairing Covenantor's
obligations hereunder, the Company may at any time and from time to time assign
its rights and obligations hereunder to Investing or LaBranche LP (and have such
rights and obligations reassigned to it or to any other subsidiary or
affiliate). This Agreement shall be binding upon and inure to the benefit of the
Company Group and its assigns.

         (d) Without limiting the provisions of Section 7(a) hereof, if any
provision of this Agreement is finally held to be invalid, illegal or
unenforceable (whether in whole or in part), such provision shall be deemed
modified to the extent, but only to the extent, of such invalidity, illegality
or unenforceability and the remaining provisions shall not be affected thereby.

         (e) Except as expressly provided herein, this Agreement shall not
confer on any person other than the Company Group and Covenantor any rights or
remedies hereunder.

                                PLEDGE AGREEMENT

         This PLEDGE AGREEMENT, dated as of June ___, 1999 (the "AGREEMENT"), is
by and between LaBranche & Co Inc., a Delaware corporation (the "COMPANY"), and
the individual whose name appears at the end of this Agreement ("PLEDGOR").

                                    RECITALS

         A. COVENANTS. Pledgor and the Company have entered into an Agreement
Relating to Noncompetition and Other Covenants (the "NONCOMPETITION AGREEMENT"),
dated as of the date hereof, in respect of, inter alia, Pledgor's obligations
(the "OBLIGATIONS") to keep information concerning the Company, LaBranche & Co.,
a New York limited partnership ("LABRANCHE LP"), and LaB Investing Co. L.L.C., a
New York limited liability company ("INVESTING") (the Company, LaBranche LP and
Investing being collectively or individually, as applicable, referred to herein
as the "COMPANY GROUP"), confidential, not to engage in competitive activities,
not to solicit listed companies or the Company Group's employees, and to
cooperate with the Company Group in maintaining certain relationships following
the termination of Pledgor's employment with the Company Group. In addition,
Pledgor has agreed to certain provisions regarding arbitration, choice of law
and choice of forum, injunctive relief and submission to jurisdiction with
respect to the enforcement of the Obligations.

         B. THE PLEDGE. Pursuant to the Noncompetition Agreement, Pledgor has
agreed to pay a certain amount of liquidated damages (the "LIQUIDATED DAMAGES")
to the Company in respect of any breach by Pledgor of any of the Obligations. As
security for the timely payment of Liquidated Damages, Pledgor has agreed to
pledge to the Company Group shares (the "PLEDGED SHARES") of common stock of the
Company (the "COMMON STOCK"), or other collateral described below, all as set
forth herein.

         NOW, THEREFORE, in consideration of the premises contained herein and
for other good and valuable consideration, the receipt and adequacy of which are
hereby acknowledged, the parties hereto agree as follows:

         1.       PLEDGE.

                  (a) Unless otherwise requested by Pledgor pursuant to the last
sentence of Section 1(b), as collateral security for the full and timely payment
of Liquidated Damages, Pledgor hereby delivers, deposits, pledges, transfers and
assigns to the Company, in form transferable by delivery, and creates for the
benefit of the Company a perfected first priority security interest in, Pledged
Shares with a Fair Market Value (as defined in Section l(d)) on the date hereof
equal to the amount of Liquidated Damages (and all certificates or other
instruments or documents evidencing the Pledged Shares) and, except as set forth
in Section 2(a), all proceeds thereof (together with any securities or property
to be delivered to the Company pursuant to Section 2(b) and, upon substitution
or delivery in accordance with Section l(b), any Substitute Collateral (as
defined in


                                      -1-
<PAGE>

Section l(b)), "PLEDGED SECURITIES"). Pledgor herewith delivers to the Company
appropriate undated security transfer powers duly executed in blank (or other
documents deemed necessary or appropriate by the Company to give the Company
control (as defined in the Uniform Commercial Code of the State of New York (the
"UCC"))) (such transfer powers and other appropriate documents, the "CONTROL
DOCUMENTS") in respect of Pledged Securities, and will deliver Control Documents
for all Pledged Securities to be pledged hereunder from time to time.

         (b) During the term of this Agreement, Pledgor may, upon the prior
written approval of the Board of Directors of the Company, substitute for
Pledged Securities readily marketable direct obligations of the United States,
any agency thereof, or any triple-A rated sovereign, shares of Common Stock, or
other collateral acceptable to the Board of Directors of the Company in its sole
and absolute discretion (collateral other than Pledged Shares, the "SUBSTITUTE
COLLATERAL") with a Fair Market Value on the date of substitution equal to or
greater than the Fair Market Value on such date of the Pledged Securities to be
released in exchange therefor. Upon such substitution, the Pledged Securities
replaced by such Substitute Collateral shall be released from the pledge
hereunder.

         (c) If Pledgor is not prohibited from doing so by the terms of the
Exchange Agreement dated as of the date hereof among the Company Group and the
individuals listed on Schedule A thereto (the "EXCHANGE AGREEMENT"), the
Stockholders' Agreement dated as of the date hereof among the Company and the
individuals listed on Schedules I and II thereto (the "STOCKHOLDERS'
AGREEMENT"), any other written agreement with the Company, or any law or
regulation or Company policy (collectively, the "RESTRICTIONS"), this Agreement
shall not prohibit Pledgor from disposing of Pledged Shares, provided that such
disposition shall be made expressly subject to all of the Company's rights
hereunder, that the provisions of this Agreement shall (as described in Section
l(a)) apply to all proceeds of such disposition, and that such disposition shall
be permitted only if the Company shall have determined that such disposition
will not result in the loss for any period by the Company of the perfection of
its first priority security interest in such proceeds, and provided further,
that the proceeds of such disposition are cash, Tender or Exchange Offer
Consideration or a combination thereof, with an aggregate Fair Market Value on
the date of such disposition equal to or greater than the Fair Market Value on
such date of the Pledged Shares so disposed. Pledgor shall give the Company
prior written notice of any proposed transaction under this Section 1(c). For
purposes of this Agreement, "TENDER OR EXCHANGE OFFER CONSIDERATION" means the
consideration issuable for Pledged Shares pursuant to any tender or exchange
offer in which the Pledgor is not prohibited from participating by the
Restrictions.

         (d) For purposes of this Agreement, the "Fair Market Value" of any
Pledged Security means, as of any date (1) in the case of a Pledged Security
that is a share of Common Stock, the average of the daily closing prices for a
share of Common Stock on the principal securities exchange or market on which
the Common Stock is traded for the 20 consecutive business days before the date
in question (the "AVERAGE CLOSING PRICE"), provided, however, that the Fair
Market Value of a share of Common Stock for purposes of determining the initial
amount to be pledged as of the date of this Agreement shall be deemed to be the
initial public offering price in the initial public offering by the Company of
its Common Stock; and provided, further, that in


                                      -2-
<PAGE>

connection with any taking of ownership by the Company of Pledged Securities
under Section 3 hereof, the Average Closing Price shall be determined as the
average of the daily closing prices for a share of Common Stock on the principal
securities exchange or market on which the Common Stock is traded for the 20
consecutive business days before the date the Enforcement Notice (as hereafter
defined) was given, and (2) otherwise, the fair market value thereof as
determined in good faith by the Company. Any good faith determination by the
Company of the Fair Market Value of any Pledged Security will be binding on
Pledgor.

         2. ADMINISTRATION OF SECURITY. The following provisions shall govern
the administration of Pledged Securities:

                  (a) So long as no Payment Event (as defined below) has
occurred and is continuing, Pledgor shall (subject to any restrictions imposed
under the Stockholders' Agreement) be entitled to vote Pledged Securities and to
exercise all of Pledgor's right under the Stockholders' Agreement in respect of
the Pledged Shares, and to receive and retain all regular quarterly cash
dividends and distributions and, except as set forth in Section 2(b) below,
other distributions thereon and to give consents, waivers and ratifications in
respect thereof. As used herein, a "PAYMENT EVENT" shall mean the failure by
Pledgor to make any payment of Liquidated Damages upon demand by the Company
therefor as provided in the Noncompetition Agreement.

                  (b) If Pledgor becomes entitled to receive, or receives, any
certificate representing Pledged Securities (or other security that may succeed
Pledged Securities or any security issued as a dividend or distribution in
respect of Pledged Securities) in respect of any stock split, reverse stock
split, stock dividend, spinoff, split up, merger or other combination, exchange
or distribution in connection with any reclassification, increase or reduction
of capital, in each case, with respect to Pledged Securities, Pledgor agrees to
accept the same as the Company's agent and to hold the same in trust on behalf
of and for the benefit of the Company and to deliver the same forthwith to the
Company in the exact form received, with the endorsement of Pledgor when deemed
necessary or appropriate by the Company of undated security transfer powers duly
executed in blank, to be held by the Company, subject to the terms of this
Agreement, as additional collateral security for Liquidated Damages.

                  (c) Pledgor hereby agrees that the Company is authorized to
hold Pledged Securities through one or more custodians. The Company and its
agents (and its and their assigns) shall have no obligation in respect of
Pledged Securities, except to hold and dispose of the same in accordance with
the terms of this Agreement. In the event that Pledgor substitutes cash for
Pledged Securities as provided in Section l(b) or 1(c), the Company shall
determine in its sole discretion the manner in which such cash shall be invested
during the term of this Agreement.

                  (d) Pledgor agrees with the Company that: (1) Pledgor will
not, and will not purport to, grant or suffer liens or encumbrances against
(excluding for such purpose the Stockholders' Agreement), or except as provided
in Section 1(c), sell, transfer or dispose of, any Pledged Securities other than
to or in favor of the Company; (2) the Company is authorized, at any time and
from time to time, to file financing statements and give notice to third parties
regarding


                                      -3-
<PAGE>

Pledged Securities without Pledgor's signature to the extent permitted by
applicable law, to transfer all or any part of Pledged Securities to the
Company's name or that of its nominee, and, subject to the provisions of Section
2(a), to exercise all rights as if the absolute owner thereof; and (3) Pledgor
has provided the Company with Pledgor's true legal name and principal residence,
and Pledgor will not change Pledgor's name without 30 days' prior written notice
to the Company

                  (e) Subject to the earlier disposition and application of
Pledged Securities pursuant to this Agreement following a Payment Event, Pledged
Securities shall be released from the pledge hereunder, and the lien hereby
created in such Pledged Securities shall simultaneously be released, upon the
earliest to occur of (1) Pledgor's death, (2) payment in cash or other
satisfaction by Pledgor of all Liquidated Damages, or (3) the fifth anniversary
of the IPO Date (as defined in the Noncompetition Agreement), and all remaining
Pledged Securities shall be thereupon released from the pledge hereunder and
this Agreement shall terminate. Notwithstanding the foregoing, no Pledged
Securities shall be released from the pledge hereunder pursuant to this Section
2(e), if there are one or more pending disputes between Pledgor and the Company
as to the occurrence of a Payment Event or as to the right of the Company or the
Company Group to exercise its remedies under this Agreement or the
Noncompetition Agreement, including realization against Pledged Securities in
accordance with Section 3 hereof, and this Agreement shall not terminate until
the resolution of all such disputes.

                  (f) The Company shall immediately upon request by Pledgor
execute and deliver to Pledgor such instruments, deeds, transfers, assurances
and agreements, in form and substance as Pledgor shall reasonably request,
including the withdrawal or termination of any financing statements and
amendments thereto, or the filing, withdrawal, termination or amendment of any
other document required under applicable law to evidence the termination of the
security interest created hereunder with respect to any securities that are
released from the pledge hereunder in accordance with the provisions of this
Agreement.

         3. REMEDIES IN CASE OF A PAYMENT EVENT. If a Payment Event has occurred
and is continuing, the Company shall have the rights and remedies of a secured
party under Article 9 of the UCC. To the extent required and permitted by
applicable law, the Company will give Pledgor notice of the time and place of
any public sale or of the time after which any private sale or other disposition
of Pledged Securities is to be made, by sending notice at least three days
before the time of sale or disposition, which Pledgor hereby agrees is
reasonable. The Company need not give such notice if not required by the UCC.
Pledgor acknowledges the possibility that the public sale of some or all Pledged
Securities by the Company may not be made without a then existing and effective
registration statement under the Securities Act of 1933, as amended. Pledgor
acknowledges and agrees with the Company that the Company has no affirmative
obligation to prepare or keep effective any such registration statement and
agrees that at any private sale of Pledged Securities may be sold at a price
that is less than the price which might have been obtained at a public sale or
that is less than the aggregate outstanding amount of Liquidated Damages. For so
long as Pledged Securities consist of securities of a type customarily sold in a
recognized market or which are the subject of widely distributed standard price
quotations, the Company may, as its remedy hereunder, take ownership of such
number of Pledged Securities as are necessary (based upon the Fair Market


                                      -4-
<PAGE>

Value thereof) to satisfy the then unpaid portion of Liquidated Damages (without
payment of any cash consideration) by giving written notice to Pledgor (the
"ENFORCEMENT NOTICE"). Effective upon the giving of the Enforcement Notice, and
without further action on the part of the parties to this Agreement, the Company
shall be deemed to have (1) taken ownership and disposed of the lesser of (A)
all Pledged Securities or (B) such whole number of Pledged Securities as has a
Fair Market Value at least equal to the then unpaid Liquidated Damages; and (2)
received proceeds in the amount of the Fair Market Value of such Pledged
Securities and applied such proceeds to the payment of any then unpaid
Liquidated Damages. Any excess net proceeds from the deemed sale of such Pledged
Securities will continue to be held as Pledged Securities under this Agreement
until returned in accordance with Section 2(e). Nothing in this Agreement,
however, shall require the Company to take ownership of Pledged Securities in
accordance with this Section 3 in order to satisfy Pledgor's obligation to pay
Liquidated Damages.

         4. PLEDGOR'S OBLIGATIONS NOT AFFECTED. Except as provided in Section
9(b), the obligations of Pledgor under this Agreement shall remain in full force
and effect without regard to, and shall not be impaired or affected by (a) any
subordination, amendment or modification of or addition or supplement to this
Agreement, the Noncompetition Agreement, the Exchange Agreement or any
assignment or transfer thereof; (b) any exercise or non-exercise by the Company
of any right, remedy, power under or in respect of this Agreement, the
Noncompetition Agreement, the Exchange Agreement or any waiver of any such
right, remedy, power or privilege; (c) any waiver, consent, extension,
indulgence or other action or inaction in respect of this Agreement, the
Noncompetition Agreement, the Exchange Agreement or any assignment or transfer
of any thereof; (d) any bankruptcy, insolvency, reorganization, arrangement,
readjustment, composition, liquidation or the like, of the Company, LaBranche LP
or Investing whether or not Pledgor shall have notice or knowledge of any of the
foregoing; (e) any substitution of collateral pursuant to Sections l(b) or 1(c);
or (f) any other act or omission to act or delay of any kind by Pledgor, the
Company or any other person or any other circumstance whatsoever which might,
but for the provisions of this clause (f), constitute a legal and equitable
discharge of Pledgor's obligations hereunder.

         5. ATTORNEYS-IN-FACT. Each of the Company, George M.L. LaBranche, IV
and James G. Gallagher, from time to time, acting separately, are hereby
appointed the attorneys-in-fact of Pledgor for the purpose of carrying out the
provisions of this Agreement and taking any action and executing any instrument
that the Company, George M.L. LaBranche, IV or James G. Gallagher reasonably may
deem necessary or advisable to accomplish the purposes hereof, which
appointments as attorneys-in-fact are irrevocable as ones coupled with an
interest.

         6. TERMINATION. Upon the earliest to occur of the events set forth in
Section 2(e) hereof, this Agreement shall terminate and the Company shall return
to Pledgor the remaining Pledged Securities, except as otherwise provided in
such Section.

         7. NOTICES. All notices or other communications required or permitted
to be given hereunder shall be delivered as provided in the Noncompetition
Agreement.


                                      -5-
<PAGE>

         8. NO THIRD PARTY BENEFICIARIES. Except as expressly provided herein,
this Agreement shall not confer on any person other than the Company and Pledgor
any rights or remedies hereunder.

         9. MISCELLANEOUS.

                  (a) This Agreement and Section 8 of the Noncompetition
Agreement contain the entire understanding and agreement between Pledgor and the
Company with respect to the matters expressly covered therein and supersede any
other agreement, written or oral, pertaining to such matters.

                  (b) This Agreement may not be amended or modified other than
by a written agreement executed by Pledgor and the Company or its successors,
nor may any provision hereof be waived other than by a writing executed by
Pledgor or the Company or its successors; provided, that any waiver, amendment
or modification of any of the provisions of this Agreement will not be effective
against the Company without the written consent of the Chief Executive Officer
of the Company or its successors, or such individual's designee. Pledgor may
not, directly or indirectly (including by operation of law), assign Pledgor's
rights or obligations hereunder without the prior written consent of the Chief
Executive Officer of the Company or its successors, or such individual's
designee, and any such assignment by Pledgor in violation of this Agreement
shall be void. This Agreement shall be binding upon Pledgor's permitted
successors and assigns. Without impairing Pledgor's obligations hereunder, the
Company may at any time and from time to time assign its rights and obligations
hereunder to any of its subsidiaries or affiliates (and have such rights and
obligations reassigned to it or to any other subsidiary or affiliate). This
Agreement shall be binding upon and inure to the benefit of the Company Group
and its assigns.

                  (c) If any provision of this Agreement is finally held to be
invalid, illegal or unenforceable (whether in whole or in part), such provision
shall be deemed modified to the extent, but only to the extent, of such
invalidity, illegality or unenforceability and the remaining provisions shall
not be affected thereby.

                  (d) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES
OF CONFLICTS OF LAWS, AND SHALL BE SUBJECT TO THE PROVISIONS OF SECTIONS 9, 10
AND 11 OF THE NONCOMPETITION AGREEMENT.

                  (e) The captions in this Agreement are for convenience of
reference only and shall not define or limit the provisions hereof.

                             STOCKHOLDERS' AGREEMENT

         This STOCKHOLDERS' AGREEMENT (this "AGREEMENT"), dated as of August
___, 1999, is by and among (i) LaBranche & Co Inc., a Delaware corporation (the
"COMPANY"), (ii) the Exchanging Members (as defined below) listed on Schedule I
hereto and (iii) the Employee Stockholders (as defined below) listed on
Schedules I and II hereto. The Exchanging Members and Employee Stockholders are
collectively referred to herein as the "STOCKHOLDERS." Except as otherwise
provided herein, capitalized terms used herein have the respective meanings
ascribed thereto in Article IV of this Agreement.

                              W I T N E S S E T H :

         WHEREAS, the Company, LaB Investing Co. L.L.C., a New York limited
liability company ("INVESTING"), and the Exchanging Members have entered into an
Exchange Agreement, dated as of the date hereof (the "EXCHANGE AGREEMENT"),
pursuant to which the Exchanging Members have agreed to contribute their
respective membership interests in Investing to the Company in exchange for
common stock, par value $.01 per share ("COMMON STOCK"), of the Company (or, in
the case of Steven C. Berger, Paul Redmond and Robert W. Keelips, III, a
combination of shares of Common Stock and cash) (the "LLC EXCHANGE") in
connection with the Company's proposed initial public offering of shares of
Common Stock (the "IPO");

         WHEREAS, the Company, the Exchanging Members and the Employee
Stockholders desire to enter into certain agreements with respect to the
Transfer (as defined below) and voting of their Common Stock and various other
matters in order to continue harmonious relationships among themselves with
respect to the conduct of the business and affairs of the Company and LaBranche
& Co., a New York limited partnership of which Investing is the sole general
partner ("LABRANCHE LP"); and

         WHEREAS, it is a condition under the Exchange Agreement that the
parties hereto enter into this Agreement.

         NOW THEREFORE, in consideration of the premises and of the mutual
agreements, covenants and provisions herein contained and for good and valuable
consideration, the receipt of which is hereby acknowledged, the parties hereto
agree as follows:

                                    ARTICLE I

                      LIMITATIONS ON TRANSFER OF SECURITIES

         Section 1.1. GENERAL. Each Stockholder agrees that he or she shall not
Transfer any Covered Securities beneficially owned by him or her, except in
accordance with all of the following: (a) the terms
<PAGE>

of this Agreement, (b) the restrictions on the transfer of the Company's
securities contemplated by the Plan of Incorporation of LaBranche LP, dated as
of June 10, 1999, (c) in the case of employees of the Company Group, any trading
restrictions generally applicable to employees of the Company Group, (d) the
terms of any "lock-up" agreement required by the underwriters of the IPO and (e)
the terms of any other contract or agreement with the Company or other
undertaking by which such Stockholder is bound and to which such Covered
Securities are subject.

         Section 1.2. GENERAL TRANSFER RESTRICTIONS.

                  (a) Each Stockholder agrees that he or she may Transfer
Covered Securities only as follows, subject to applicable securities laws:

                           (i) up to 33-1/3% of such Covered Securities at any
         time after the third anniversary of the date of the consummation of the
         IPO;

                           (ii) up to an additional 33-1/3% of such Covered
         Securities at any time after the fourth anniversary of the date of the
         consummation of the IPO; and

                           (iii) all of such Covered Securities at any time
         after the fifth anniversary of the date of the consummation of the IPO.

                  (b) Notwithstanding the provisions set forth in Section 1.2(a)
above, each Stockholder agrees that for so long as such Stockholder remains in
the employ of any member of the Company Group, such Stockholder shall at all
times be the sole beneficial Owner of that number of Covered Securities equal to
25% or more of the aggregate number of Covered Securities (1) beneficially owned
by such Stockholder immediately after the consummation of the IPO and (2)
beneficial ownership of which is acquired by such Stockholder thereafter, with
no reduction in such aggregate number for Covered Securities disposed of by such
Stockholder.

         Section 1.3. COMPLIANCE WITH CERTAIN RESTRICTIONS.

                  (a) Each Stockholder agrees that, with respect to all Covered
Securities beneficially owned by such Stockholder, he or she shall comply with
the restrictions on Transfer imposed by the underwriters of the IPO.

                  (b) Each Stockholder agrees that he or she shall, at the
request of the Company, comply with any future restrictions on Transfer imposed
by or with the consent of the Company from time to time in connection with any
future offerings of securities of the Company, whether by the Company or by any
securityholder of the Company and whether or not such restrictions on Transfer
refer to such Stockholder by name.

<PAGE>

                  (c) Each Stockholder agrees that, with respect to all Covered

or any party to an agreement with the Company to account for a business
combination by the pooling of interests method.

         Section 1.4. TRANSFERS FOLLOWING DEATH OR DISABILITY. Notwithstanding
any other provisions of this Agreement, upon the death or Disability of any

Covered Securities free of any provisions of this Agreement, subject to the
provisions of any other agreement relating to this subject matter.

         Section 1.5. TRANSFERS WITH THE CONSENT OF BOARD OF DIRECTORS.
Notwithstanding any other provisions of this Agreement, a Stockholder may
Transfer any number of Covered Securities at any time with the prior written
consent of the Board of Directors, which consent may be withheld or delayed, or
granted on such terms and conditions as the Board of Directors may determine, in
its sole discretion.

         Section 1.6. TRANSFERS TO PERMITTED TRANSFEREES. Notwithstanding any
other provision of this Agreement, a Stockholder may Transfer any number of
Covered Securities to a Permitted Transferee at any time, provided that it shall
be a condition to any such Transfer that such Permitted Transferee agree in
writing to be bound by all the provisions of this Agreement as if such Permitted
Transferee were a Stockholder from and after the date of such Transfer for all
purposes of this Agreement.

         Section 1.7. COMPLIANCE WITH LAW AND REGULATIONS. Each Stockholder
agrees that any Transfer of Covered Securities by such Stockholder shall be in
compliance with any applicable constitution, rule or regulation of, or any
applicable policy of, any of the exchanges or associations or other institutions
with which any member of the Company Group has membership or other privileges
(including, without limitation, the NYSE), federal and securities laws, and any
applicable law, rule or regulation of the Commission or any other governmental
agency having jurisdiction.

         Section 1.8. LEGEND ON CERTIFICATES; ENTRY OF STOP TRANSFER ORDERS. (a)
Each Stockholder agrees that each outstanding certificate representing any
Covered Securities that are subject to this Agreement shall bear an endorsement
noted conspicuously on each such certificate reading substantially as follows:

         "The securities evidenced by this certificate have not been registered
         under the Securities Act of 1933, as amended (the "Act"), or under any
         state securities law and may not be sold, offered for sale, pledged,
         hypothecated or otherwise transferred in the absence of an effective
         registration statement with respect thereto under the Act and any
         applicable state securities law, or the receipt by the Company of an
         opinion of counsel, reasonably satisfactory to the Company, that such
         registration is not required.

         The securities represented by this certificate are subject to the
         provisions of a Stockholders' Agreement dated as of August __, 1999
         among the Company and certain


                                       3
<PAGE>

         persons listed on Schedules I and II to such agreement, a copy of which
         is on file at the principal executive office of the Company, and such
         securities may be sold, assigned, pledged or otherwise transferred only
         in accordance with such agreement."

                  (b) Each Stockholder agrees to the entry of stop transfer
orders against the Transfer of legended certificates representing securities of
the Company not in compliance with this Agreement.

         Section 1.9. CERTIFICATES TO BE HELD BY COMPANY. (a) Each Stockholder
agrees that the certificates representing his or her Covered Securities shall be
issued in the name of a nominee holder to be designated by the Company and shall
be held in custody by the Company at its principal office. The Company shall,
upon the request of any such Stockholder or the estate of any Stockholder, as
the case may be, in writing addressed to the Secretary of the Company or any
officer designated by the Secretary (which request shall include a
representation by such Stockholder or his or her estate that he or she is then
permitted to Transfer a specified number of Covered Securities under the
provisions of this Agreement), promptly release from custody the certificates
representing such specified number of such Stockholder's Covered Securities
which are then intended and permitted to be Transferred under the provisions of
this Agreement.

                  (b) Subject to the Stockholders having provided appropriate
written direction to the Company, whenever the nominee holder shall receive any
cash dividend or other cash distribution upon any Covered Securities deposited
pursuant to Section 1.8(a), the Company shall cause the nominee holder to
distribute promptly such cash dividend or other distribution (by any other
manner that it may determine, net of its charges and expenses in effecting such
conversion), by checks drawn on a bank in the United States, to the Stockholders
in proportion to the number of Covered Securities Owned by each of them
respectively; provided that the Company shall cause the nominee holder to make
appropriate adjustments in the amounts so distributed in respect of any amounts
required to be withheld by the nominee holder from any distribution on account
of taxes. The nominee holder shall distribute only such amount as can be
distributed without distributing to any Stockholder a fraction of one cent, and
any balance not so distributable shall be held by the nominee holder (without
liability for interest thereon) and shall be added to and become part of the
next sum received by the nominee holder for distribution to the Stockholders.

         Section 1.10. TRANSFERS IN VIOLATION OF AGREEMENT VOID. Any attempted
Transfer of Covered Securities not made in accordance with the provisions of
this Agreement shall be void, and the Company shall not register, or cause or
permit the registration, of Common Stock Transferred in violation of this
Agreement.

<PAGE>

Directors shall make such adjustments to or interpretations of the restrictions
of Section 1.2 (and, if it so determines, any other provisions hereof) as it
shall deem necessary or desirable to carry out the intent of such provisions(s).
If the Board of Directors deems it desirable, any such adjustments may take
effect from the record date or another appropriate date.

exercise and enforcement of remedies hereunder. If a Stockholder who is also a

term or provision shall be deemed replaced by a term or provision that is valid
and enforceable and that comes closest to expressing the intention of the
invalid or unenforceable term or provision.

         Section 5.10. REPRESENTATIVES, SUCCESSORS AND ASSIGNS. This Agreement
shall be binding upon and inure to the benefit of the respective parties hereto
and their respective legatees, legal representatives, successors and assigns;
provided that Stockholders may not assign, delegate or otherwise Transfer any of
their rights or obligations under this Agreement except with the prior written
consent of the Board of Directors, and any assignment without such consent by
the Board of Directors shall be void.

         Section 5.11. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD
TO THE CONFLICT OF LAWS PRINCIPLES OR RULES THEREOF).

         Section 5.12. SPECIFIC PERFORMANCE. Each of the parties hereto
acknowledges that it will be impossible to measure in money the damage to the

provisions of Article I or II and each party hereto agrees that in the event of
any such failure, neither the Company nor any Stockholder will have an adequate
remedy at law. Therefore, the Company and each Stockholder, in addition to all
of the other remedies which may be available, shall have the right to equitable

1. AUTHORIZATION OF NOTES

      The Company will authorize the issue and sale of $20,000,000 aggregate
principal amount of its 8.17% Subordinated Notes due September 15, 2002 (the
"Notes", such term to include any such notes issued in substitution therefor
pursuant to Section 13 of this Agreement and the Other Agreements). The Notes
shall be substantially in the form of Exhibit 1, with such changes therefrom, if
any, as may be approved by you and the Company. Certain capitalized terms used
in this Agreement are, defined in Schedule B; references to a "Schedule" or an
"Exhibit" are, unless otherwise specified, to a Schedule or an Exhibit attached
to this Agreement; and references to Sections are, unless otherwise specified,
references to Sections of this Agreement.

2. SALE AND PURCHASE OF NOTES

      Subject to the terms and conditions of this Agreement, the Company will
issue and sell to you and you will purchase from the Company, at the Closing
provided for in Section 3, Notes in the principal amount specified below your
name in Schedule A at the purchase price of 100% of the principal amount
thereof. Contemporaneously with entering into this Agreement, the Company is
entering into separate Note Purchase Agreements (the "Other Agreements")
identical with this Agreement with each of the other purchasers named in
Schedule A (the "Other Purchasers"), providing for the sale at such Closing to
each of the Other Purchasers of Notes in the principal amount specified below
its name in Schedule A. Your obligation hereunder and the obligations of the
Other Purchasers under the Other Agreements are several and not joint
obligations and you shall have no obligation under any Other Agreement and no
liability to any Person for the performance or non-performance by any Other
Purchaser thereunder.

3. CLOSING

      The sale and purchase of the Notes to be purchased by you and the Other
Purchasers shall occur at the offices of Hebb & Gitlin, One State Street,
Hartford, Connecticut at 10:00 a.m., local Hartford time, at a closing (the
"Closing") on September 15, 1997 or on such other Business Day thereafter on or
prior to September 30, 1997 as may be agreed upon by the Company and you and the
Other Purchasers. At the Closing the Company will deliver to you the Notes to be
purchased by you in the form of a single Note (or such greater number of Notes
in denominations of at least $100,000 as you may request) dated the date of the
Closing and registered in your name (or in the name of your nominee), against
delivery by you to the Company or its order of immediately available funds in
the amount of the purchase price therefor

binding obligation of the Company enforceable against the Company in accordance
with its terms, except as such enforceability may be limited by

            (a) applicable bankruptcy, insolvency, reorganization, moratorium or
      other similar laws affecting the enforcement of creditors' rights
      generally, and

            (b) general principles of equity (regardless of whether such

business and principal properties of the Company. Except as disclosed in
Schedule 5.3, this Agreement, the Memorandum, the documents, certificates and
other writings delivered to you by or on behalf of the Company in connection
with the transactions contemplated hereby and the financial statements listed in

material fact or omit to state any material fact necessary to make the
statements therein not misleading in light of the circumstances under which they
were made. Except as disclosed in the Memorandum or as expressly described in
Schedule 5.3, or in one of the documents, certificates or other writings
identified therein, or in the financial statements listed in Schedule 5.5, since

to the Company (excluding facts of a general, publicly known, economic or
political nature) that has had or, so far as the Company can now reasonably
foresee, could reasonably be expected to have a Material Adverse Effect and that

specifically for use in connection with the transactions contemplated hereby.

prepared in accordance with GAAP consistently applied throughout the periods
involved except as set forth in the notes thereto (subject, in the case of any

such as to require a consent, approval or authorization of, or filing,
registration or qualification with, any Governmental Authority on the part of
the Company as a condition to the execution and delivery of this Agreement, the
offer, issuance, sale or delivery of the Notes, or the performance of the
obligations hereunder or thereunder, except for consents, approvals and

<PAGE>

      employee pension benefit plans listed on Schedule 5.12 are managed,
      controlled or invested by, or are on deposit with, any Purchaser or any
      affiliate thereof. The terms "employee pension benefit plan" and "plan

      employer" has the meaning specified in section 4062 of ERISA and
      "affiliate" and "employer security" have the meanings specified in section
      407(d) of ERISA).

            (b) Investment Advice. Neither the Company nor any of its Affiliates
      has offered or delivered any evaluation or other investment advice on any
      basis in respect of the advisability of the purchase of the Notes to any
      Purchaser in any manner that would cause the Company or Affiliates to
      become a "party in interest" (as defined in section 3 of ERISA) or a
      "disqualified person" (as defined in section 4975 of the IRC) with respect
      to any "employee benefit plan" (as defined in section 3 of ERISA) the
      assets of which are being used to acquire the Notes.

            (c) Prohibited Transactions. The execution and delivery of this
      Agreement and the issuance and sale of the Notes hereunder will not
      involve any transaction that is subject to the prohibitions of section 406
      of ERISA or in connection with which a tax could be imposed pursuant to
      section 4975(c)(1)(A) through section 4975(D), inclusive, of the IRC.

            (d) Defined Benefit Plan. The Company has never at any time had any

      each Pension Plan are in compliance with ERISA, except for such failures
      to comply that in the aggregate for all such failures could not reasonably
      be expected to have a Material Adverse Effect.

            (f) Multiemployer Plans. Neither the Company nor any ERISA Affiliate
      contributes to, maintains, or has any liability or obligation in respect
      of, a Multiemployer Plan.

Person other than you, the Other Purchasers and not more than 50 other
Institutional Investors, each of which has been offered the Notes at a private
sale for investment. Neither the Company nor anyone acting on its behalf has
taken, or will take, any action that would subject the issuance or sale of the
Notes to the registration requirements of section 5 of the Securities Act.

      buying or carrying any margin stock within the meaning of Regulation G of
      the Board of Governors of the Federal Reserve System (12 CFR 207), or for
      the purpose of buying or carrying or trading in any securities under such
      circumstances as to involve the Company in a violation of Regulation X of
      said Board (12 CFR 224) or to involve any broker or dealer in a violation
      of Regulation T of said Board (12 CFR 220). As used in this Section, the

      meanings assigned to them in said Regulation G.

      outstanding Debt of the Company as of August 31, 1997 (and specifying, as

      which date there has been no Material change in the amounts, interest
      rates, sinking funds, installment payments, collateral or maturities of
      the Debt of the Company. The Company is not in default and no waiver of
      default is currently in effect, in the payment of any principal or
      interest on any Debt of the Company and no event or condition exists with
      respect to any Debt of the Company that would permit (or that with notice
      or the lapse of time, or both, would permit) one or more Persons to cause
      such Debt to become due and payable before its stated maturity or before
      its regularly scheduled dates of payment. No notice has been issued in
      respect of non-renewal of the maturity of the "scheduled maturity date" of
      any Debt listed on Schedule 5.15 that constitutes Permitted Subordinated
      Debt.

            (b) Except as disclosed in Schedule 5.15, the Company has not agreed
      or consented to cause or permit in the future (upon the happening of a
      contingency or otherwise) any of its property, whether now owned or
      hereafter acquired, to be subject to a Lien not permitted by Section 10.6.

      5.16 Foreign Assets Control Regulations, etc.

      Neither the sale of the Notes by the Company hereunder nor its use of the
proceeds thereof will violate the Trading with the Enemy Act, as amended, or any
of the foreign assets control regulations of the United States Treasury
Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling
legislation or executive order relating thereto.

            (a) Broker-Dealer Status. The Company is registered as a
      broker-dealer with the SEC under the Exchange Act and with state

            (c) SIPC Assessments. The Company is not in arrears with respect to
      any assessment made by the SIPC.

            (d) Notes as Net Capital. The Company has obtained the approval of
      the NYSE to classify the Notes as subordinated loan agreements and Net
      Capital. No other approval or consent of the NYSE, the SEC or any other
      Governmental Authority is necessary to permit such classification.

      5.19 Priority of Notes.

      There is no Debt of the Company that is in any manner subordinated to any
other Debt of the Company and that is not junior in right of payment and
performance to the right of payment and performance of the Notes. To the best
knowledge of the Company, all Intercreditor Agreements executed and delivered
pursuant to Section 4.11 are duly authorized, executed and delivered by the
holders of subordinated liabilities of the Company subject to such agreements,
and such agreements are enforceable in accordance with their terms against such
Persons, except as such enforceability is limited by

            (a) applicable bankruptcy, insolvency, reorganization, moratorium or
      other similar laws affecting the enforcement of creditors' rights
      generally, and

            (b) general principles of equity (regardless of whether such
      enforceability is considered in a proceeding in equity or at law).

prepayment date with respect to such principal amount. The Company will give
each holder of Notes written notice of each optional prepayment under this

principal amount accrued to such date and the applicable Make-Whole Amount, if
any. From and after such date, unless the Company shall fail to pay such
principal amount when so due and payable, together with the interest and
Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall

                        (E) specify the last date upon which the offer can be
                  accepted or rejected, and the consequences of failing to
                  provide an acceptance or rejection as provided in Section
                  8.6(c),

                        (F) specify the principal amount of each Note
                  outstanding, and the interest that would be due on each Note
                  offered to be paid if such offer was accepted, accrued to the
                  Change in Control Payment Date,

                        (G) provide the calculation (with details) of an
                  estimated Make-Whole Amount, if any, (calculated as if the
                  date of such notice was the date of payment) due in connection
                  with such payment, and

                        (H) be executed by a Responsible Official.

            (c) Acceptance, Rejection. To accept or reject such offered payment,
      a holder of Notes shall send a notice of acceptance or rejection to the
      Company prior to the expiration of the specified offer period. A failure
      to respond to any such written offer of payment as provided in this
      Section 8.6(c) shall be deemed to constitute an acceptance of such offer.

            (d) Deferral of Obligation to Pay. The obligation of the Company to
      pay the principal of the Notes pursuant to the offers required by Section
      8.6(b) and accepted in accordance with Section 8.6(c) is subject to the
      occurrence of the Change in Control in respect of which such offers and
      acceptances have been made. In the event that such Change in Control does
      not occur on or prior to the specified Change in Control Payment Date in
      respect thereof, such payment shall be deferred until and shall be made on
      the Change in Control Date (as deferred). The Company shall keep each
      holder of Notes reasonably and timely informed of

                  (i) any deferral in, and the expected dates of, the Change in
            Control Payment Date, and

<PAGE>

                  (ii) any determination by the Company that efforts to effect
            such Change in Control have ceased or been abandoned (in which case
            the offers and acceptances made pursuant to this Section 8.6 in
            respect of such Change in Control shall be deemed rescinded,
            provided that if such abandoned Change in Control is revived, it
            shall be deemed to be a new Change in Control hereunder).

      If the Change in Control Payment Date is deferred by more than 5 Business
      Days, the Company will promptly deliver to the holders of the Notes the
      information required by Section 8.6(b)(iv), updated accordingly.

            (e) Material Alteration in Transaction. If, prior to the Change in
      Control Payment Date, the terms of the transaction constituting the
      related Change in Control are altered in any material respect, the Company
      will immediately notify each holder of Notes of the details of such
      alteration. Each holder of Notes will have the right to reverse its
      acceptance or rejection of such offer (if already accepted or rejected)
      until the end of the 5th Business Day following the day on which such
      holder is notified by the Company of such alteration. Each holder of Notes
      which reverses its acceptance or rejection of such offer shall notify the
      Company thereof during such 5 Business Day period. If any holder of Notes
      fails to notify the Company of a reversal of its acceptance or rejection
      of such offer during such 5 Business Day period, such holder of Notes
      shall be deemed to have confirmed such acceptance or rejection. The Change
      in Control Payment Date will be deferred, to the extent necessary, to
      accommodate such 5 Business Day period, and the Company will promptly
      deliver to the holders of the Notes the information required by Section
      8.6(b)(iv), updated accordingly as necessary.

            (f) Payment. The offered payment shall be made at 100% of the
      principal amount of the Notes to be prepaid (together with any interest
      accrued and unpaid thereon, determined as of the Change in Control Payment
      Date). Two Business Days prior to the making of such payment, the Company
      shall deliver to each holder of Notes by facsimile transmission a
      certificate of a Responsible Official specifying the details of the
      calculation of such Make-Whole Amount as of the specified payment date,
      including a copy of the source of interest rate information used in such
      calculation.

            (g) Waiver of Event of Acceleration. Each holder which shall have
      rejected an offer of payment made in accordance with this Section 8.6
      shall be deemed to have

                  (i) waived the right to accelerate the maturity of such
            holder's Notes in connection with such Change in Control and the
            Event of Acceleration caused by such Change in Control, and

                  (ii) agreed that no Event of Acceleration shall have occurred
            as a result of such Change in Control.

      Such waiver shall not affect the rights of the holders of the Notes in
      respect of any other Change in Control.

      8.7 Make-Whole Amount.

      The term "Make-Whole Amount" means, with respect to any Note, an amount
equal to the excess, if any, of the Discounted Value of the Remaining Scheduled
Payments with respect to the Called Principal of such Note over the amount of
such Called Principal, provided that the


LaBranche & CO.                                          NOTE PURCHASE AGREEMENT
                                       19
<PAGE>

Make-Whole Amount may in no event be less than zero. For the purposes of
determining the Make-Whole Amount, the following terms have the following
meanings:

            "Called Principal" means, with respect to any Note, the principal of
      such Note that is to be prepaid pursuant to Section 8.2 or has become or
      is declared to be immediately due and payable pursuant to Section 11.2 or
      Section 11.4, as the context requires.

            "Discounted Value" means, with respect to the Called Principal of
      any Note, the amount obtained by discounting all Remaining Scheduled
      Payments with respect to such Called Principal from their respective
      scheduled due dates to the Settlement Date with respect to such Called
      Principal, in accordance with accepted financial practice and at a
      discount factor (applied on the same periodic basis as that on which
      interest on the Notes is payable) equal to the Reinvestment Yield with
      respect to such Called Principal.

            "Reinvestment Yield" means, with respect to the Called Principal of
      any Note, 0.75% per annum plus the yield to maturity implied by

                  (i) the yields reported, as of 10:00 A.M. (New York City time)
            on the second Business Day preceding the Settlement Date with
            respect to such Called Principal, on the display designated as "Page
            678" on the Telerate Access Service (or such other display as may
            replace Page 678 on Telerate Access Service) for actively traded
            U.S. Treasury securities having a maturity equal to the Remaining
            Average Life of such Called Principal as of such Settlement Date, or

                  (ii) if such yields are not reported as of such time or the
            yields reported as of such time are not ascertainable, the Treasury
            Constant Maturity Series Yields reported, for the latest day for
            which such yields have been so reported as of the second Business
            Day preceding the Settlement Date with respect to such Called
            Principal, in Federal Reserve Statistical Release H.15 (519) (or any
            comparable successor publication) for actively traded U.S. Treasury
            securities having a constant maturity equal to the Remaining Average
            Life of such Called Principal as of such Settlement Date.

      Such implied yield will be determined, if necessary, by

                  (a) converting U.S. Treasury bill quotations to
            bond-equivalent yields in accordance with accepted financial
            practice, and

                  (b) interpolating linearly between

                        (1) the actively traded U.S. Treasury security with the
                  duration closest to and greater than the Remaining Average
                  Life, and

                        (2) the actively traded U.S. Treasury security with the
                  duration closest to and less than the Remaining Average Life.

            "Remaining Average Life" means, with respect to any Called
      Principal, the number of years (calculated to the nearest one-twelfth
      year) remaining until the Scheduled Maturity Date.

<PAGE>

            "Remaining Scheduled Payments" means, with respect to the Called
      Principal of any Note, the payment on the Scheduled Maturity Date of such
      Called Principal and all interest thereon that would be due after the
      Settlement Date with respect to such Called Principal if no payment of
      such Called Principal were made prior to the Scheduled Maturity Date,
      provided that if such Settlement Date is not a date on which interest
      payments are due to be made under the terms of the Notes, then the amount
      of the next succeeding scheduled interest payment will be reduced by the
      amount of interest accrued to such Settlement Date.

            "Settlement Date" means, with respect to the Called Principal of any
      Note, the date on which such Called Principal is to be prepaid pursuant to
      Section 8 or has become or is declared to be immediately due and payable
      pursuant to Section 12, as the context requires.

9.    AFFIRMATIVE COVENANTS

      The Company covenants that so long as any of the Notes are outstanding:

      9.1   Compliance with Law.

      The Company will comply with all laws, ordinances or governmental rules or
regulations to which each of them is subject, including, without limitation,
Environmental Laws and all laws, rules and regulations of the SEC, the NYSE and

permits, franchises and other governmental authorizations necessary to the
ownership of their respective properties or to the conduct of their respective
businesses (including, without limitation, those required by the SEC, the NYSE
and the NASD), in each case to the extent necessary to ensure that
non-compliance with such laws, ordinances or governmental rules or regulations
or failures to obtain or maintain in effect such licenses, certificates,
permits, franchises and other governmental authorizations could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect provided that the failure of the Company to be registered as a
broker-dealer in good standing with the SEC under the Exchange Act, to be a
member organization in good standing of the NYSE, or to maintain its status as a
specialist broker in good standing with the NYSE, shall be a breach of this
Section 9.1.

      9.2   Insurance.

      The Company will maintain, with financially sound and reputable insurers,
insurance with respect to their respective properties and businesses against
such casualties and contingencies, of such types, on such terms and in such
amounts (including deductibles, co-insurance and self-insurance, if adequate
reserves are maintained with respect thereto) as is customary in the case of
entities of established reputations engaged in the same or a similar business
and similarly situated. Schedule 9.2 contains a summary of insurance coverages
of the Company in existence on the Closing Date.

      9.3   Maintenance of Properties.

      The Company will maintain and keep, or cause to be maintained and kept,
their respective properties in good repair, working order and condition (other
than ordinary wear and tear), so that the business carried on in connection
therewith may be properly conducted at all times, provided that this Section
shall not prevent the Company from discontinuing the operation and


LaBranche & CO                         21                NOTE PURCHASE AGREEMENT
<PAGE>

the maintenance of any of its properties if such discontinuance is desirable in
the conduct of its business and the Company has concluded that such
discontinuance could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

      9.4   Payment of Taxes and Claims.

      The Company will file all tax returns required to be filed in any
jurisdiction and to pay and discharge all taxes shown to be due and payable on
such returns and all other taxes, assessments, governmental charges, or levies
imposed on them or any of their properties, assets, income or franchises, to the
extent such taxes, assessments, charges and levies have become due and payable
and before they have become delinquent and all claims for which sums have become
due and payable that have or might become a Lien on properties or assets of the
Company, provided that the Company need not pay any such tax or assessment or
claims if

            (a) the amount, applicability or validity thereof is contested by
      the Company on a timely basis in good faith and in appropriate
      proceedings, and the Company has established adequate reserves therefor in
      accordance with GAAP on the books of the Company, or

            (b) the nonpayment of all such taxes, assessments, charges and
      levies in the aggregate could not reasonably be expected to have a
      Material Adverse Effect.

      9.5   Legal Existence, etc.

      Subject to Section 10.5, the Company will at all times preserve and keep
in full force and effect its legal existence.

      9.6   Ranking of Notes.

      The Notes shall at all times rank as direct, unsecured, subordinated
obligations of the Company and shall rank at senior to all other subordinated
Debt of the Company present and future.

      9.7   Line of Business.

      The Company will not engage in any businesses other than the businesses in
which the Company is engaged on the date of this Agreement, securities
brokerage, clearing, and securities trading businesses, and financial and
investment services related thereto.

      9.8   Compliance with Margin Regulations.

      No provision of this Agreement is intended by the Company or the holders
of the Notes, and no provision of this Agreement shall be construed by any other
Person to provide "indirect security" in any "margin stock" owned by the
Company, and no provision of this Agreement is intended to restrict the right or
ability of the Company to sell, pledge, or otherwise dispose of margin stock
owned by it to the extent that such a restriction would be in violation of
Regulation G, Regulation T or Regulation U of the Board of Governors of the
Federal Reserve System, and any provision of this Agreement that may be
construed to impose a restriction that is inconsistent with such Regulations is
intended to be, and shall be, construed as being subject to and limited by said
Regulations. The terms "indirect security" and "margin stock" have the meanings
assigned to them by such Regulation G.

      11.4  Remedies Upon an Event of Default.

      Upon the occurrence of an Event of Default, the unpaid principal amount of
the Notes, together with accrued interest thereon and any Make-Whole Amount in
respect thereof, shall mature and become immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by the Company, provided that the right of the holders of Notes to
receive any payment of principal thereof, together with accrued interest thereon
and any Make-Whole Amount due with respect thereto, shall remain subordinate as
set forth in Section 12.4.

      11.5  Other Remedies.

            (a) Other Remedies. During the existence of an Event of Default or
      an Event of Acceleration, irrespective of whether the Notes then
      outstanding shall have been declared to be due and payable and
      irrespective of whether any holder of Notes then outstanding shall
      otherwise have pursued or be pursuing any other rights or remedies, any
      holder of Notes may proceed to protect and enforce its rights hereunder
      and under the Notes by exercising such remedies as are available to such
      holder in respect thereof under applicable law, either by suit in equity
      or by action at law, or both, whether for specific performance of any
      agreement contained herein or in aid of the exercise of any power granted
      herein, provided that the maturity of such holder's Notes may be
      accelerated only in accordance with Section 11.2 and Section 11.4, and

      any Make-Whole Amount due with respect thereto, shall remain subordinate
      as set forth in Section 12.4.

            (b) Nonwaiver and Expenses. No course of dealing on the part of any
      holder of Notes nor any delay or failure on the part of any holder of
      Notes to exercise any right shall operate as a waiver of such right or
      otherwise prejudice such holder's rights, powers and remedies. If the
      Company shall fail to pay when due any principal of, Make-Whole Amount due
      with respect to, or interest on, any Note, or shall fail to comply with
      any other material provision hereof, the Company shall pay to each holder
      of Notes, to the extent permitted by law, such further amounts as shall be
      sufficient to cover the costs and expenses, including but not limited to
      reasonable attorneys' fees incurred by such holder in collecting any sums
      due on such Notes or in otherwise assessing, analyzing or enforcing any
      rights or remedies that are or may be available to it.

      11.6  Annulment of Acceleration of Notes.

      If a declaration is made pursuant to Section 11.2(a), then and in every
such case, the Required Holders may, by written instrument filed with the

      any moneys due on or pursuant hereto or the Notes;

            (b) all arrears of interest upon all the Notes and all other sums
      payable hereunder and under the Notes (except any principal of, or

      have been duly paid; and

affect any subsequent Default, Event of Default or Event of Acceleration or

            Required Note Payment by the Examining Authority or the SEC) stated
            in such applicable paragraph;

      (the Net Capital necessary to enable the Company to avoid such suspension
      of its obligation to pay a Required Note Payment being referred to as the
      "Required Payment Minimum Capital").

            (b) Actions Taken with Respect to Suspension. During any such period
      when the obligation to make a Required Note Payment is suspended in
      accordance with Section 12.1(a), the Company shall, as promptly as is
      consistent with the protection of its customers, reduce its business to a
      condition whereby such Required Note Payment with accrued interest thereon
      could be paid (together with the payment of any other Payment Obligation
      of the Company payable at or prior to the date of such Required Note
      Payment) without the Company's Net Capital being below the Required
      Payment Minimum Capital. The Company shall provide the holders of the
      Notes and the NYSE immediate notice of the termination of such suspension,
      and no later than the 5th day after delivery of such notice, make such
      Required Note Payment.

      is made and immediately after such Required Note Payment, the Net Capital
      of the Company is less than the Required Payment Minimum Capital with
      respect thereto, each holder of Notes receiving all or a portion of such
      Required Note Payment shall (whether or not such holder had any knowledge
      or notice that such Required Note Payment was made in violation of Section
      12.1(a)) repay to the Company, its successors or assigns, on a pro rata
      basis among the holders of the Notes receiving such payment, such portion
      of the sum so paid (without interest) as necessary to cause the Company to
      be in compliance under Section 12.1(a) with respect to the portion of such
      Required Note Payment not so repaid (such compliance to be determined
      based on facts and circumstances in effect on the date the Company first
      made such Required Note Payment); provided that any suit by or on behalf
      of the Company for the recovery of any such Required Note Payment must be
      commenced within 2 years of the date such Required Note Payment was first
      paid by the Company. Such repaid portion of such


LaBranche & CO.                        32                NOTE PURCHASE AGREEMENT
<PAGE>

      Required Note Payment shall be held by the Company as if such repaid
      portion of such Required Note Payment had never been made.

      12.2 Suspension of Optional Payments.

            (a) Suspension. The Company may offer to make a payment of principal
      of the Notes pursuant to Section 8.2 and Section 8.6 only with the prior
      written permission of the Examining Authority (such payment being
      hereinafter referred to as an "Optional Note Payment"). No Optional Note
      Payment may be made during the 365 day period following the Closing Date.
      No Optional Note Payment shall be made if after giving effect thereto (and
      to all other payments of principal of outstanding subordination agreements
      of the Company including the return of any Secured Demand Note (and any
      collateral held therefor) the maturity or accelerated maturity of which
      are scheduled to occur on or before the earlier of 6 months after the date
      such Optional Note Payment is to occur or the Scheduled Maturity Date) and
      without reference to any projected profit or loss of the Company, any of
      the following conditions exist:

                  (i) Aggregate Debt -- in the event that the Company is not
            operating pursuant to the alternative net capital requirement
            provided for in paragraph (a)(1)(ii) of Rule 15c3-1, the Aggregate
            Debt of the Company would exceed 1,000% of the Net Capital of the
            Company (or such other percentum as may be made applicable to the
            Company at the time of such Optional Note Payment by the Examining

      (the Net Capital necessary to enable the Company to avoid such suspension

      is made and immediately after such Optional Note Payment, the Net Capital
      of the Company is less than the Optional Payment Minimum Capital with

      assigns, on a pro rata basis among the holders of the Notes receiving such
      payment, such portion of the sum so paid (without interest) as necessary
      to cause the Company to be in compliance under Section 12.2(a) with
      respect to the portion of such Optional Note Payment not so repaid (such
      compliance to be determined based on facts and circumstances in effect on
      the date the Company first made such Optional Note Payment); provided that
      any suit by or on behalf of the Company for the recovery of any such
      Optional Note Payment must be commenced within 2 years of the date such
      Optional Note Payment was first paid by the Company. Such repaid portion
      of such Optional Note Payment shall be held by the Company as if such
      repaid portion of such Optional Note Payment had never been made.

      12.3 Recapture Interest.

      Interest shall accrue at the interest rate provided in the Notes for
overdue payments of principal on each payment or prepayment of principal of the
Notes (and on all interest and Make-Whole Amount paid together with such
payment) that is repaid by any holder of Notes as provided in Section 12.1(c) or
Section 12.2(b) (such repaid amount referred to herein as the "Recaptured
Amount") from the date such payment was first paid by the Company to such holder
until the date when such Recaptured Amount, and the default interest thereon, is
finally, fully and indefeasibly paid by the Company to each such holder. Upon
such full, final and indefeasible payment, such holder shall pay to the Company
interest on such Recaptured Amount in respect of any period when both the
Default Rate applied to (and was indefeasibly paid to and collected by such
holder) such Recaptured Amount as provided in this Section 12.3


LaBranche & CO.                        34                NOTE PURCHASE AGREEMENT
<PAGE>

and such Recaptured Amount was in the possession of such holder, at the federal
funds overnight rate in effect from time to time during such period.

      12.4 Subordination of Obligations.

      The obligation of the Company under the Notes and this Agreement with
respect to the payment of outstanding principal of, interest on, and Make-Whole
Amount, if any, due with respect thereto, at any time when an Insolvency Event
has occurred and is continuing, is and shall be fully and irrevocably
subordinate in right of payment and subject to the prior payment or provision
for payment in full of all claims of all other present and future creditors of
the Company arising out of any matter occurring prior to the date on which the
Company's obligation to make any such payment in respect of the Notes matures
consistent with the provisions hereof, except for

            (a) claims which are the subject of subordination provisions which
      rank on the same priority as the Notes or the class of claims of which the
      Notes are a member (claims hereunder shall rank pari passu with such
      claims), and

            (b) claims which are the subject of subordination provisions which
      rank junior to the Notes or the class of claims of which the Notes are a
      member (claims hereunder shall be senior to such claims),

provided that the rights of the holders of the Notes shall rank, now and in the
future, prior and superior to any claims represented by capital, equity or other
ownership interests of the Company, including, without limitation, claims of
general partners, limited partners, stockholders, and members, and claims
derived from such interests, including, without limitation, declared
distributions or dividends in respect of such interests, regardless of the
priority such claims would otherwise have under statute or law. Claims made
senior to the Notes pursuant to this Section 12.4 are referred to herein as
"Senior Claims".

      12.5 Insolvency Event.

      In the event of the appointment of a receiver or trustee of the Company or
in the event of its insolvency, liquidation pursuant to the SIPA or otherwise,
bankruptcy, assignment for the benefit of creditors, reorganization (whether or
not pursuant to bankruptcy laws) or any other marshalling of the assets and
liabilities of the Company (such events referred to collectively as an
"Insolvency Event"), the obligation of the Company to pay the principal of the
Notes, together with interest accrued thereon and the Make-Whole Amount, if any,
due with respect thereto, shall become due and payable in full (notwithstanding
any contrary provision of this Agreement or the Notes) but the holders of the
Notes shall not be entitled to participate or share, ratably or otherwise, in
the distribution of assets of the Company in satisfaction of such obligation to
pay the principal of the Notes, together with the interest accrued thereon and
the Make-Whole Amount, if any, due with respect thereto, until all Senior Claims
have been fully satisfied (or provision made for payment if assets of the
Company available to pay the same shall be adequate in amount to satisfy all
such claims fully). Subject to the payment in full of all Senior Claims, the
holders of Notes shall be, to the extent of distributions of Property of the
Company to the holders of Senior Claims to which the holders of Notes would be
entitled but for this Section 12, subrogated to the rights of the holders of
such Senior Claims.

      12.6 Obligations Not Impaired.

      Nothing contained in this Section 12 shall impair, as between the Company
and any holder of Notes, the obligation of the Company to pay to such holder the
principal of the Notes, interest thereon and Make-Whole Amount, if any, due with
respect thereto, as and when the same shall become due and payable in accordance
with the terms hereof to the extent that such payments are made in compliance
with Section 12.1 or Section 12.2, or require the holders of the Notes to turn
over any such payment to the Company except as provided in Section 12.1(c) and
Section 12.2(b), or subordinate the claims against the Company of the holders of
the Notes to any other Person except the holder of a Senior Claim, and then only
in connection with an Insolvency Event. Nothing contained in this Section 12
shall prevent any holder of any Notes from exercising all rights, powers and
remedies otherwise permitted by applicable law, this Agreement and the Notes.

      12.7 Non-liability of NYSE.

      You warrant and represent that the Notes are not being purchased in
reliance upon the standing of the Company as a member organization of the NYSE

compliance with the Constitution, Rules and practices of the NYSE. You have made
such investigation of the Company and its members, partners, officers and
directors as you deem necessary and appropriate under the circumstances. You are
not relying upon the NYSE to provide any information concerning or relating to
the Company and you agree that the NYSE has no responsibility to disclose to the
holders of the Notes any information concerning or relating to the Company which
it may now, or at any future time, have. Neither the NYSE, its Special Trust
Fund, nor any director, officer, trustee or employee of the NYSE or said Trust
Fund shall be liable to the holders of the Notes with respect to this Agreement
or the repayment the Notes or of any interest thereon or other amounts due with
respect thereto.

      12.8 Status of Proceeds of Notes.

      The proceeds of the loan evidenced hereby shall be dealt with in all
respects as capital of the Company, shall be subject to the risks of its
business, and may be deposited in an account or accounts in the Company's name
in any bank or trust company.

      12.9 Notices to NYSE.

      Whenever prior written notice to the NYSE is required pursuant to the
provisions of this Agreement, such written notice shall be given by the Company

            Attention Chief Accountant of Division of Trading and Markets,
            and/or

            and which is then designated by the CFTC as the Company's DSRO;

            (b) whenever prior written consent, permission or approval of the
      NYSE is required pursuant to the provisions of this Agreement, the Company
      shall also obtain the prior written consent, permission or approval of the
      CFTC and/or of the DSRO; and

            (c) whenever the Company receives written notice of acceleration of
      maturity pursuant to the provisions of this Agreement, the Company shall
      promptly give written notice thereof to the CFTC at the address above
      stated and to the DSRO, as required.

      12.11 Set-off.

      The holders of the Notes agree that they are not taking and will not take
or assert as security for the payment of the Notes any security interest in or
Lien upon, whether created by contract, statute or otherwise, any Property of
the Company or any Property in which the Company may have an interest, which is
or at any time may be in the possession or subject to the control of any holder
of Notes. The holders of the Notes hereby waive, and further agree that they
will not seek to obtain payment of the Notes in whole or in any part by
exercising, any right of set-off they may assert or possess in connection with,
and related to, the Notes, whether created by contract, statute or otherwise.
Any agreement between the Company and the holders of the Notes (whether in the
nature of a general loan and collateral agreement, a security or pledge
agreement or otherwise) shall be deemed amended hereby to the extent necessary
so as not to be inconsistent with the provisions of this Section 12.11.

      12.12 Amendment.

      Notwithstanding any other provision of this Agreement, this Agreement and
the Notes shall not be modified or amended without the prior written approval of
the NYSE. This instrument embodies the entire agreement between the Company and

will be executed without the prior written consent of the NYSE.

each holder of one or more Notes, each transfer thereof and the name and address
of each transferee of one or more Notes shall be registered in such register.
Prior to due presentment for registration of transfer, the Person in whose name

notice or knowledge to the contrary. The Company shall give to any holder of a
Note that is an Institutional Investor promptly upon request therefor, a
complete and correct copy of the names and addresses of all registered holders

for registration of transfer, duly endorsed or accompanied by a written
instrument of transfer duly executed by the registered holder of such Note or
his attorney duly authorized in writing and accompanied by the address for
notices of each transferee of such Note or part thereof), the Company shall
execute and deliver, at the Company's expense (except as provided below), one or
more new Notes (as requested by the holder thereof) in exchange therefor, in an

holder may request and shall be substantially in the form of Exhibit 1. Each
such new Note shall be dated and bear interest from the date to which interest

transferred in denominations of less than $100,000, provided that if necessary
to enable the registration of transfer by a holder of its entire holding of
Notes, one Note may be in a denomination of less than $100,000. Any transferee,

shall be deemed to have made the representation set forth in Section 6.2.

      13.3 Limitation on Transfer of Notes.

      No holder of Notes may, without the prior written consent of the Company,
transfer its Notes to a Competitor or an affiliate of a Competitor. The Company

law or regulation.

      13.4 Replacement of Notes.

      Upon receipt by the Company of evidence reasonably satisfactory to it of
the ownership of and the loss, theft, destruction or mutilation of any Note
(which evidence shall be, in the case of an Institutional Investor, notice from
such Institutional Investor of such ownership and such loss, theft, destruction
or mutilation), and

            (a) in the case of loss, theft or destruction, of indemnity
      reasonably satisfactory to it (provided that if the holder of such Note
      is, or is a nominee for, a Purchaser or


LaBranche & CO.                        38                NOTE PURCHASE AGREEMENT

      another holder of a Note with a minimum net worth of at least $50,000,000,
      such Person's own unsecured agreement of indemnity shall be deemed to be
      satisfactory), or

            (b) in the case of mutilation, upon surrender and cancellation
      thereof,

the Company at its own expense shall execute and deliver, in lieu thereof, a new
Note, dated and bearing interest from the date to which interest shall have been
paid on such lost, stolen, destroyed or mutilated Note or dated the date of such
lost, stolen, destroyed or mutilated Note if no interest shall have been paid
thereon.

14. PAYMENTS ON NOTES

a bank or trust company in such jurisdiction.

      14.2 Home Office Payment.

      So long as you or your nominee shall be the holder of any Note, and

contrary, the Company will pay all sums becoming due on such Note for principal,
Make-Whole Amount, if any, and interest by the method and at the address
specified for such purpose below your name in Schedule A, or by such other
method or at such other address as you shall have from time to time specified to
the Company in writing for such purpose, without the presentation or surrender
of such Note or the making of any notation thereon, except that upon written
request of the Company made concurrently with or reasonably promptly after
payment or prepayment in full of any Note, you shall surrender such Note for
cancellation, reasonably promptly after any such request, to the Company at its
principal executive office or at the place of payment most recently designated
by the Company pursuant to Section 14.1. Prior to any sale or other disposition
of any Note held by you or your nominee you will, at your election, either
endorse thereon the amount of principal paid thereon and the last date to which
interest has been paid thereon or surrender such Note to the Company in exchange
for a new Note or Notes pursuant to Section 13.2. The Company will afford the
benefits of this Section 14.2 to any Institutional Investor that is the direct

      the holder of each Note at the time outstanding affected thereby,

                  (i) subject to the provisions of Section 11 relating to
            acceleration or rescission, change the amount or time of any
            prepayment or payment of principal

            amendment or waiver, or

                  (iii) amend any of Section 8, Section 11.1(a), Section
            11.1(b), Section 11.2 through Section 11.6, inclusive, or Section
            20.

      17.2 Solicitation of Holders of Notes.

            (a) Solicitation. The Company will provide each holder of the Notes
      (irrespective of the amount of Notes then owned by it) with sufficient
      information sufficiently far in advance of the date a decision is
      required, to enable such holder to make an informed and considered
      decision with respect to any proposed amendment, waiver or consent in
      respect of any of the provisions hereof or of the Notes. The Company will
      deliver executed or true and correct copies of each amendment, waiver or
      consent effected pursuant to the provisions of this Section 17 to each
      holder of outstanding Notes promptly following the date on which it is
      executed and delivered by, or receives the consent or approval of, the
      requisite holders of Notes.

            (b) Payment. The Company will not directly or indirectly pay or
      cause to be paid any remuneration, whether by way of supplemental or
      additional interest, fee or otherwise, or grant any security, to any
      holder of Notes as consideration for or as an inducement to the entering
      into by any holder of Notes of any waiver or amendment of any of the terms
      and provisions hereof unless such remuneration is concurrently paid, or

      holder of Notes then outstanding even if such holder did not consent to
      such waiver or amendment.

      17.3 Binding Effect, etc.

      Any amendment or waiver consented to as provided in this Section 17
applies equally to all holders of Notes and is binding upon them and upon each
future holder of any Note and upon the Company without regard to whether such
Note has been marked to indicate such amendment or waiver. No such amendment or
waiver will extend to or affect any obligation, covenant, agreement, Default,
Event of Default or Event of Acceleration not expressly amended or waived or
impair any right consequent thereon. No course of dealing between the Company
and the holder of any Note nor any delay in exercising any rights hereunder or
under any Note shall operate as a waiver of any rights of any holder of such
Note. As used herein, the term "this Agreement" and references thereto shall
mean this Agreement as it may from time to time be amended or supplemented.

      17.4 Notes held by Company, etc.

      Solely for the purpose of determining whether the holders of the requisite
percentage of the aggregate principal amount of Notes then outstanding approved

provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or
render unenforceable such provision in any other jurisdiction.

            (b) the terms and provisions of the Existing Note Purchase Agreement
      shall continue in full force and effect.

The Company hereby acknowledges, confirms, reaffirms and ratifies all of its
obligations and duties under the Note Purchase Agreement and all agreements
related thereto. This Amendment is not a limitation on the ability of any holder
of Notes to exercise any of its rights and remedies due to any Default, Event of
Acceleration or Event of Default in the Note Purchase Agreement, nor does this
Amendment constitute an agreement or obligation of any holder of Notes to give
its consent to any future amendment of the Note Purchase Agreement or to any
future transaction that would, absent consent of the holders of the Notes,
constitute a Default, an Event of Acceleration or Event of Default under the
Note Purchase Agreement. This Amendment may not be contradicted by evidence of
any actual or alleged prior, contemporaneous or subsequent understandings or
agreements of the parties, written or oral, express or implied, other than a
writing which expressly amends or supersedes this Amendment or the Note Purchase
Agreement. Upon the effectiveness of this Amendment, each reference in the Note
Purchase Agreement to any Note Purchase Agreement and each agreement or document
referring thereto shall mean and be a reference to the Note Purchase Agreement
(as amended hereby).

To Each of the Purchasers Listed in
       the Attached Schedule A:

Ladies and Gentlemen:

      LaBranche & Co., a New York limited partnership (the "Company"), agrees
with you as follows:

1. AUTHORIZATION OF NOTES

      The Company will authorize the issue and sale of $15,000,000 aggregate
principal amount of its 7.69% Subordinated Notes due June 3, 2008 (the "Notes",
such term to include any such notes issued in substitution therefor pursuant to
Section 13 of this Agreement and the Other Agreements). The Notes shall be
substantially in the form of Exhibit 1, with such changes therefrom, if any, as
may be approved by you and the Company. Certain capitalized terms used in this
Agreement are defined in Schedule B; references to a "Schedule" or an "Exhibit"
are, unless otherwise specified, to a Schedule or an Exhibit attached to this
Agreement; and references to Sections are, unless otherwise specified,
references to Sections of this Agreement.

2. SALE AND PURCHASE OF NOTES

      Subject to the terms and conditions of this Agreement, the Company will
issue and sell to you and you will purchase from the Company, at the Closing
provided for in Section 3, Notes in the principal amount specified below your
name in Schedule A at the purchase price of 100% of the principal amount
thereof. Contemporaneously with entering into this Agreement, the Company is
entering into separate Note Purchase Agreements (the "Other Agreements")
identical with this Agreement with each of the other purchasers named in
Schedule A (the "Other Purchasers"), providing for the sale at such Closing to
each of the Other Purchasers of Notes in the principal amount specified below
its name in Schedule A. Your obligation hereunder and the obligations of the
Other Purchasers under the Other Agreements are several and not joint
obligations and you shall have no obligation under any Other Agreement and no
liability to any Person for the performance or non-performance by any Other
Purchaser thereunder.

3. CLOSING

      The sale and purchase of the Notes to be purchased by you and the Other
Purchasers shall occur at the offices of Fulbright & Jaworski L.L.P., 666 5th
Avenue, New York, NY at 10:00 a.m., local New York City time, at a closing (the
"Closing") on June 3, 1998 or on such other Business Day thereafter on or prior
to July 1, 1998 as may be agreed upon by the Company and you and the Other
Purchasers. At the Closing the Company will deliver to you the Notes to be
purchased by you in the form of a single Note (or such greater number of Notes
in denominations of at least $100,000 as you may request) dated the date of the
Closing and registered in your name (or in the name of your nominee), against
delivery by you to the Company or its order of immediately available funds in
the amount of the purchase price therefor


LaBranche & CO.                                          NOTE PURCHASE AGREEMENT
<PAGE>

ABA# 021-000-018 FBO LaBranche & Co., A/C # 8540904708 Attn. Rick Rivera
212-635-6739. If at the Closing the Company shall fail to tender such Notes to
you as provided above in this Section 3, or any of the conditions specified in
Section 4 shall not have been fulfilled to your satisfaction, you shall, at your
election, be relieved of all further obligations under this Agreement, without
thereby waiving any rights you may have by reason of such failure or such
nonfulfillment.

4. CONDITIONS TO CLOSING

      Your obligation to purchase and pay for the Notes to be sold to you at the
Closing is subject to the fulfillment to your satisfaction, at the Closing, of
the following conditions:

      4.1 Representations and Warranties.

      The representations and warranties of the Company in this Agreement shall
be correct as of the date hereof and at the time of the Closing.

      4.2 Performance; No Default.

      The Company shall have performed and complied with all agreements and
conditions contained in this Agreement required to be performed or complied with
by it prior to or at the Closing and after giving effect to the issue and sale
of the Notes (and the application of the proceeds thereof as contemplated by
Section 5.13) no Default, Event of Default or Event of Acceleration shall have
occurred and be continuing. Except as set forth on Schedule 4.2, the Company
shall not have entered into any transaction since June 1, 1997 that would have
been prohibited by Section 10.4, had such Section applied since such date.

      4.3 Compliance Certificate.

      The Company shall have delivered to you an Officers' Certificate dated the
date of the Closing, certifying that the conditions specified in Section 4.1,
Section 4.2 and Section 4.10 have been fulfilled, and certifying as to the
resolutions attached thereto and other proceedings relating to the
authorization, execution and delivery of the Notes and the Agreements.

      4.4 Opinions of Counsel.

      You shall have received opinions in form and substance satisfactory to
you, dated the date of the Closing

            (a) from Fulbright & Jaworski L.L.P., counsel for the Company,
      covering the matters set forth in Exhibit 4.4(a) and covering such other
      matters incident to the transactions contemplated hereby as you or your
      counsel may reasonably request (and the Company hereby instructs its
      counsel to deliver such opinion to you), and

            (b) from Hebb & Gitlin, your special counsel in connection with such
      transactions, substantially in the form of Exhibit 4.4(b) and covering
      such other matters incident to such transactions as you may reasonably
      request.

      4.5 Purchase Permitted By Applicable Law, etc.

      On the date of the Closing your purchase of Notes shall

            (a) be permitted by the laws and regulations of each jurisdiction to
      which you are subject, without recourse to provisions (such as section
      1405(a)(8) of the New York Insurance Law) permitting limited investments
      by insurance companies without restriction as to the character of the
      particular investment,

            (b) not violate any applicable law or regulation (including, without
      limitation, regulations of the Board of Governors of the Federal Reserve
      System in respect of margin lending), and

            (c) not subject you to any tax, penalty or liability under or
      pursuant to any applicable law or regulation, which law or regulation was
      not in effect on the date hereof.

If requested by you, you shall have received an Officer's Certificate certifying
as to such matters of fact as you may reasonably specify to enable you to
determine whether such purchase is so permitted.

      4.6 Net Capital.

      The Company shall provide such evidence as is reasonably satisfactory to
you evidencing that the Company has obtained the approval of the NYSE to
classify the Notes as a component of the Net Capital of the Company.

      4.7 Sale of Other Notes.

      Contemporaneously with the Closing the Company shall sell to the Other
Purchasers and the Other Purchasers shall purchase the Notes to be purchased by
them at the Closing as specified in Schedule A.

      4.8 Payment of Special Counsel Fees.

      Without limiting the provisions of Section 15.1, the Company shall have
paid on or before the Closing the fees, charges and disbursements of your
special counsel referred to in Section 4.4 to the extent reflected in a
statement of such counsel rendered to the Company at least one Business Day
prior to the Closing.

      4.9 Private Placement Number.

      A Private Placement Number issued by Standard & Poor's CUSIP Service
Bureau (in cooperation with the Securities Valuation Office of the National

authorized by all necessary action on the part of the Company and the General
Partner, and this Agreement constitutes, and upon execution and delivery thereof

      other similar laws affecting the enforcement of creditors' rights
      generally, and

            (b) general principles of equity (regardless of whether such

      authorizations, patents, copyrights, service marks, trademarks and trade

      5.11 Compliance with ERISA.

            (a) Disclosure. Schedule 5.11 sets forth all "employee pension
      benefit plans" with respect to which the Company or any "affiliate" of the
      Company is a "plan sponsor" or a "substantial employer" or in respect of
      which the Notes could constitute an "employer security." To the best
      knowledge of the Company, no part of the assets of any of the employee
      pension benefit plans listed on Schedule 5.12 are managed, controlled or
      invested by, or are on deposit with, any Purchaser or any affiliate
      thereof. The terms "employee pension benefit plan" and "plan sponsor" have
      the meanings specified in section 3 of ERISA, "substantial employer" has
      the meaning specified in section 4062 of ERISA and "affiliate" and
      "employer security" have the meanings specified in section 407(d) of

      has offered or delivered any evaluation or other investment advice on any
      basis in respect of the advisability of the purchase of the Notes to any
      Purchaser in any manner that would cause the Company or Affiliates to
      become a "party in interest" (as defined in section 3 of ERISA) or a
      "disqualified person" (as defined in section 4975 of the IRC) with respect
      to any "employee benefit plan" (as defined in section 3 of ERISA) the
      assets of which are being used to acquire the Notes.

            (c) Prohibited Transactions. The execution and delivery of this
      Agreement and the issuance and sale of the Notes hereunder will not
      involve any transaction that is subject to the prohibitions of section 406
      of ERISA or in connection with which a tax could be imposed pursuant to
      section 4975(c)(1)(A) through section 4975(D), inclusive, of the IRC.

      liability or obligation in respect of any "defined benefit plan" (as
      defined in section 3 of ERISA).

      each Pension Plan are in compliance with ERISA, except for such failures
      to comply that in the aggregate for all such failures could not reasonably
      be expected to have a Material Adverse Effect.

            (f) Multiemployer Plans. Neither the Company nor any ERISA Affiliate
      contributes to, maintains, or has any liability or obligation in respect
      of, a Multiemployer Plan.

or any similar securities for sale to, or solicited any offer to buy any of the
same from, or otherwise approached or negotiated in respect thereof with, any
Person other than you, the Other Purchasers and not more than 50 other
Institutional Investors, each of which has been offered the Notes at a private
sale for investment. Neither the Company nor anyone acting on its behalf has
taken, or will take, any action that would subject the issuance or sale of the
Notes to the registration requirements of section 5 of the Securities Act.

      5.13 Use of Proceeds; Margin Regulations.

            (a) Use of Proceeds. The proceeds of the Notes shall be dealt with
      in all respects as capital of the Company, shall be subject to the risks
      of its business, and may be deposited in an account or accounts in the
      Company's name in any bank or trust company.

            (b) Margin Regulations. No part of the proceeds from the sale of the
      Notes hereunder will be used, directly or indirectly, for any purpose that

      outstanding Debt of the Company as of April 30, 1998 (and specifying, as

      which date there has been no Material change in the amounts, interest
      rates, sinking funds, instalment payments, collateral or maturities of the
      Debt of the Company. The Company is not in default and no waiver of
      default is currently in effect, in the payment of any principal or
      interest on any Debt of the Company and no event or condition exists with
      respect to any Debt of the Company that would permit (or that with notice
      or the lapse of time, or both, would permit) one or more Persons to cause
      such Debt to become due and payable before its stated maturity or before
      its regularly scheduled dates of payment. No notice has been issued in
      respect of non-renewal of the maturity of the "scheduled maturity date" of
      any Debt listed on Schedule 5.14 that constitutes Permitted Subordinated
      Debt.

      hereafter acquired, to be subject to a Lien not permitted by Section 10.6.

      5.15 Foreign Assets Control Regulations, etc.

      Neither the sale of the Notes by the Company hereunder nor its use of the

of the foreign assets control regulations of the United States Treasury
Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling
legislation or executive order relating thereto.

      securities authorities in each state where the Company is required to be
      so registered. The Company is a member organization in good standing of
      the NYSE.

            (b) Regulation T. The Company is a broker-dealer subject to the
      provisions of Regulation T (12 C.F.R. ss. 220) of the Board of Governors
      of the Federal Reserve System. The Company maintains procedures and
      internal controls designed to ensure that neither the Company nor any
      Subsidiary extends or maintains credit to or for its customers other than
      in accordance with the provisions of Regulation T, and management
      officials of the Company regularly supervise the activities of the Company
      and the Subsidiaries, and the activities of employees of each thereof, to
      ensure that neither the Company nor any Subsidiary extends or maintains
      credit to or for its customers other than in accordance with the
      provisions of said Regulation T.

            (c) SIPC Assessments. The Company is not in arrears with respect to
      any assessment made by the SIPC.

            (d) Notes as Net Capital. The Company has obtained the approval of
      the NYSE to classify the Notes as subordinated loan agreements and Net
      Capital. No other approval or consent of the NYSE, the SEC or any other
      Governmental Authority is necessary to permit such classification.

      5.18 Priority of Notes.

      There is no Debt of the Company that is in any manner subordinated to any
other Debt of the Company and that is not junior in right of payment and
performance to the right of payment and performance of the Notes. To the best
knowledge of the Company, all Intercreditor Agreements executed and delivered
pursuant to Section 4.11 are duly authorized, executed and delivered by the
holders of subordinated liabilities of the Company subject to such agreements,

      account" as defined in Department of Labor Prohibited Transaction
      Exemption ("PTE") 95-60 (issued July 12, 1995) and in respect thereof you

            "qualified professional asset manager" or "QPAM" (within the meaning
            of Part V of the QPAM Exemption), no employee benefit plan's assets
            that are included in such investment fund, when combined with the

                  (iii) the Purchaser has no knowledge of any fact or

8. REPAYMENT OF THE NOTES

      8.1 Required Repayments.

      Subject to Section 12.1, the Company shall repay, and there shall become
due and payable, $3,000,000 (or such lesser amount as may be due in accordance
with Section 8.2(b)) in principal amount of the Notes on June 3 in each year
beginning on June 3, 2004 and ending on June 3, 2008, inclusive (each such
payment date a "Mandatory Repayment Date" and each such repayment a "Mandatory
Repayment'). Each such repayment shall be at one hundred percent (100%) of the
principal amount repaid, together with interest accrued thereon to the date of
repayment. Subject to Section 12.1, the principal of the Notes shall become due
and payable in full, together with all amounts owing in respect thereof
(including all accrued interest) on June 3, 2008 (the "Scheduled Maturity
Date").

      8.2 Optional Prepayments with Make-Whole Amount.

            (a) Optional Prepayments. Subject to Section 12.2, the Company may,
      at its option, upon notice as provided below, prepay at any time all, or
      from time to time any part, of the Notes, in an amount not less than 5% of
      the aggregate principal amount of the Notes then outstanding in the case
      of a partial prepayment, at 100% of the principal amount so prepaid, plus
      the Make-Whole Amount determined for the prepayment date with respect to
      such principal amount. The Company will give each holder of Notes written
      notice of each optional prepayment under this Section 8.2 not less than 30
      days and not more than 60 days prior to the date fixed for such
      prepayment. Each such notice

                                       15
<PAGE>

      shall specify such date, the aggregate principal amount of the Notes to be
      prepaid on such date, the principal amount of each Note held by such
      holder to be prepaid (determined in accordance with Section 8.3), and the
      interest to be paid on the prepayment date with respect to such principal
      amount being prepaid, and shall be accompanied by a certificate of a
      Responsible Official as to the estimated Make-Whole Amount due in
      connection with such prepayment (calculated as if the date of such notice
      were the date of the prepayment), setting forth the details of such
      computation. Two Business Days prior to such prepayment, the Company shall
      deliver to each holder of Notes a certificate of a Responsible Official
      specifying the calculation of such Make-Whole Amount as of the specified
      prepayment date.

            (b) Effect of Prepayments and Repurchases. Each prepayment of the
      Notes pursuant to this Section 8.2, and each repurchase of Notes by the
      Company, shall reduce each of the then remaining Mandatory Repayments by a
      percentage equal to the aggregate principal amount of the Notes so paid or
      purchased divided by the aggregate principal amount of the Notes
      outstanding immediately prior to such payment or purchase.

      8.3 Allocation of Partial Prepayments.

      In the case of each partial prepayment of the Notes, the principal amount
of the Notes to be prepaid shall be allocated among all of the Notes at the time
outstanding in proportion, as nearly as practicable, to the respective unpaid
principal amounts thereof not theretofore called for prepayment.

      8.4 Maturity; Surrender, etc.

      In the case of each prepayment of Notes pursuant to this Section 8, the
principal amount of each Note to be prepaid shall mature and become due and
payable on the date fixed for such prepayment, together with interest on such
principal amount accrued to such date and the applicable Make-Whole Amount, if
any. From and after such date, unless the Company shall fail to pay such
principal amount when so due and payable, together with the interest and
Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall
cease to accrue. Any Note paid or prepaid in full shall be surrendered to the
Company and cancelled and shall not be reissued, and no Note shall be issued in
lieu of any prepaid principal amount of any Note.

      8.5 Purchase of Notes.

      The Company will not and will not permit any Affiliate to purchase,
redeem, prepay or otherwise acquire, directly or indirectly, any of the
outstanding Notes except

            (a) upon the payment or prepayment of the Notes in accordance with
      the terms of this Agreement and the Notes, or

            (b) pursuant to an offer to purchase made by the Company or an
      Affiliate pro rata to the holders of all Notes at the time outstanding
      upon the same terms and conditions.

Any such offer shall provide each holder with sufficient information to enable
it to make an informed decision with respect to such offer, and shall remain
open for at least 15 Business Days. If the holders of more than 50% of the
principal amount of the Notes then outstanding

any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant
to any provision of this Agreement and no Notes may be issued in substitution or
exchange for any such Notes.

      If the Change in Control Payment Date is deferred by more than 5 Business
      Days, the Company will promptly deliver to the holders of the Notes the
      information required by Section 8.6(b)(iv), updated accordingly.

            (e) Material Alteration in Transaction. If, prior to the Change in
      Control Payment Date, the terms of the transaction constituting the
      related Change in Control are altered in any material respect, the Company
      will immediately notify each holder of Notes of the details of such
      alteration. Each holder of Notes will have the right to reverse its
      acceptance or rejection of such offer (if already accepted or rejected)
      until the end of the 5th Business Day following the day on which such
      holder is notified by the Company of such alteration. Each holder of Notes
      which reverses its acceptance or rejection of such offer shall notify the
      Company thereof during such 5 Business Day period. If any holder of Notes
      fails to notify the Company of a reversal of its acceptance or rejection
      of such offer during such 5 Business Day period, such holder of Notes
      shall be deemed to have confirmed such acceptance or rejection. The Change
      in Control Payment Date will be deferred, to the extent necessary, to
      accommodate such 5 Business Day period, and the Company will promptly
      deliver to the holders of the Notes the information required by Section
      8.6(b)(iv), updated accordingly as necessary.

            (f) Payment. The offered payment shall be made at 100% of the
      principal amount of the Notes to be prepaid (together with any interest
      accrued and unpaid thereon, determined as of the Change in Control Payment
      Date). Two Business Days prior to the making of such payment, the Company
      shall deliver to each holder of Notes by facsimile transmission a
      certificate of a Responsible Official specifying the details of the
      calculation of such Make-Whole Amount as of the specified payment date,
      including a copy of the source of interest rate information used in such
      calculation.

            (g) Waiver of Event of Acceleration. Each holder which shall have
      rejected an offer of payment made in accordance with this Section 8.6
      shall be deemed to have

                  (i) waived the right to accelerate the maturity of such
            holder's Notes in connection with such Change in Control and the
            Event of Acceleration caused by such Change in Control, and

                  (ii) agreed that no Event of Acceleration shall have occurred
            as a result of such Change in Control.

      Such waiver shall not affect the rights of the holders of the Notes in
      respect of any other Change in Control.

      8.7 Make-Whole Amount.

      The term "Make-Whole Amount" means, with respect to any Note, an amount
equal to the excess, if any, of the Discounted Value of the Remaining Scheduled
Payments with respect to the Called Principal of such Note over the amount of
such Called Principal, provided that the Make-Whole Amount may in no event be
less than zero. For the purposes of determining the Make-Whole Amount, the
following terms have the following meanings:

            "Called Principal" means, with respect to any Note, the principal of
      such Note that is to be prepaid pursuant to Section 8.2 or has become or
      is declared to be immediately due and payable pursuant to Section 11.2 or
      Section 11.4, as the context requires.

            "Discounted Value" means, with respect to the Called Principal of
      any Note, the amount obtained by discounting all Remaining Scheduled
      Payments with respect to such Called Principal from their respective
      scheduled due dates to the Settlement Date with respect to such Called
      Principal, in accordance with accepted financial practice and at a
      discount factor (applied on the same periodic basis as that on which
      interest on the Notes is payable) equal to the Reinvestment Yield with
      respect to such Called Principal.

            "Reinvestment Yield" means, with respect to the Called Principal of
      any Note, 0.75% per annum plus the yield to maturity implied by

                  (i) the yields reported, as of 10:00 A.M. (New York City time)
            on the second Business Day preceding the Settlement Date with
            respect to such Called Principal, on the display designated as "Page
            678" on the Telerate Access Service (or such other display as may
            replace Page 678 on Telerate Access Service) for actively traded
            U.S. Treasury securities having a maturity equal to the Remaining
            Average Life of such Called Principal as of such Settlement Date, or

                  (ii) if such yields are not reported as of such time or the
            yields reported as of such time are not ascertainable, the Treasury
            Constant Maturity Series Yields reported, for the latest day for
            which such yields have been so reported as of the second Business
            Day preceding the Settlement Date with respect to such Called
            Principal, in Federal Reserve Statistical Release H.15 (519) (or any
            comparable successor publication) for actively traded U.S. Treasury
            securities having a constant maturity equal to the Remaining Average
            Life of such Called Principal as of such Settlement Date.

      Such implied yield will be determined, if necessary, by

                  (a) converting U.S. Treasury bill quotations to
            bond-equivalent yields in accordance with accepted financial
            practice, and

                  (b) interpolating linearly between

                        (1) the actively traded U.S. Treasury security with the
                  duration closest to and greater than the Remaining Average
                  Life, and

                        (2) the actively traded U.S. Treasury security with the
                  duration closest to and less than the Remaining Average Life.

            "Remaining Average Life" means, with respect to any Called
      Principal, the number of years (calculated to the nearest one-twelfth
      year) obtained by dividing

                  (a) such Called Principal into

                  (b) the sum of the products obtained by multiplying

                        (i) the principal component of each Remaining Scheduled
                  Payment with respect to such Called Principal by

                        (ii) the number of years (calculated to the nearest
                  one-twelfth year) that will elapse between the Settlement Date
                  with respect to such

                  Called Principal and the scheduled due date of such Remaining
                  Scheduled Payment.

            "Remaining Scheduled Payments" means, with respect to the Called
      Principal of any Note, all payments of such Called Principal and interest
      thereon that would be due after the Settlement Date with respect to such
      Called Principal if no payment of such Called Principal were made prior to
      its scheduled due date, provided that if such Settlement Date is not a
      date on which interest payments are due to be made under the terms of the
      Notes, then the amount of the next succeeding scheduled interest payment
      will be reduced by the amount of interest accrued to such Settlement Date
      and required to be paid on such Settlement Date.

            "Settlement Date" means, with respect to the Called Principal of any
      Note, the date on which such Called Principal is to be prepaid pursuant to
      Section 8 or has become or is declared to be immediately due and payable
      pursuant to Section 12, as the context requires.

franchises and other governmental authorizations necessary to the ownership of
their respective properties or to the conduct of their respective businesses

case to the extent necessary to ensure that non-compliance with such laws,
ordinances or governmental rules or regulations or failures to obtain or
maintain in effect such licenses, certificates, permits, franchises and other
governmental authorizations could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect provided that the
failure of the Company to be registered as a broker-dealer in good standing with
the SEC under the Exchange Act, to be a member organization in good standing of
the NYSE, or to maintain its status as a specialist broker in good standing with
the NYSE, shall be a breach of this Section 9.1.

      The Company will maintain, with financially sound and reputable insurers,
insurance with respect to their respective properties and businesses against
such casualties and contingencies, of such types, on such terms and in such

entities of established reputations engaged in the same or a similar business
and similarly situated. Schedule 9.2 contains a summary of insurance coverages
of the Company in existence on the date of Closing.

shall not prevent the Company from discontinuing the operation and the
maintenance of any of its properties if such discontinuance is desirable in the

could not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect.

jurisdiction and to pay and discharge all taxes shown to be due and payable on

extent such taxes, assessments, charges and levies have become due and payable

      Material Adverse Effect.

      Subject to Section 10.5, the Company will at all times preserve and keep
in full force and effect its legal existence.

      of its obligation to pay a Required Note Payment being referred to as the
      "Required Payment Minimum Capital").

            (b) Actions Taken with Respect to Suspension. During any such period
      when the obligation to make a Required Note Payment is suspended in
      accordance with Section 12.1(a), the Company shall, as promptly as is
      consistent with the protection of its customers, reduce its business to a
      condition whereby such Required Note Payment with accrued interest thereon
      could be paid (together with the payment of any other obligation of the

      by the Company and returnable at or prior to the payment of such Required
      Note Payment) without the Company's Net Capital being below the Required

      Required Note Payment shall (whether or not such holder had any knowledge
      or notice that such Required Note Payment was made in violation of Section
      12.1(a)) repay to the Company, its successors or assigns, on a pro rata
      basis among the holders of the Notes receiving such payment, such portion
      of the sum so paid (without interest) as necessary to cause the Company to
      be in compliance under Section 12.1(a) with respect to the portion of such
      Required Note Payment not so repaid (such compliance to be determined
      based on facts and circumstances in effect on the date the Company first
      made such Required Note Payment); provided that any suit by or on behalf
      of the Company for the recovery of any such Required Note Payment must be
      commenced within 2 years of the date such Required Note Payment was first
      paid by the Company. Such repaid portion of such Required Note Payment
      shall be held by the Company as if such repaid portion of such Required
      Note Payment had never been made.

      12.2 Suspension of Optional Payments.

            (a) Suspension. The Company may offer to make a payment of principal
      of the Notes pursuant to Section 8.2 and Section 8.6 only with the prior
      written permission of the Examining Authority (such payment being
      hereinafter referred to as an "Optional Note Payment"). No Optional Note
      Payment may be made during the 365 day period following the date of
      Closing. No Optional Note Payment shall be made if after giving effect

      subordination agreements of the Company including the return of any
      Secured Demand Note (and any collateral held therefor) the maturity or
      accelerated maturity of which are scheduled to occur on or before the
      earlier of 6 months after the date such Optional Note Payment is to occur
      or the Scheduled Maturity Date) and without reference to any projected
      profit or loss of the Company, any of the following conditions exist:

                  (i) Aggregate Indebtedness -- in the event that the Company is
            not operating pursuant to the alternative net capital requirement

<PAGE>

      (the Net Capital necessary to enable the Company to avoid such suspension
      of its obligation to pay an Optional Note Payment being referred to as the
      "Optional Payment Minimum Capital").

            (b) Recapture of Optional Note Payments. If an Optional Note Payment
      is made and immediately after such Optional Note Payment, the Net Capital
      of the Company is less than the Optional Payment Minimum Capital with
      respect thereto, each holder of Notes receiving all or a portion of such
      Optional Note Payment shall (whether or not such holder had any knowledge
      or notice that such Optional Note Payment was subject to suspension
      pursuant to Section 12.2(a)) repay to the Company, its successors or
      assigns, on a pro rata basis among the holders of the Notes receiving such
      payment, such portion of the sum so paid (without interest) as necessary
      to cause the Company to be in compliance under Section 12.2(a) with
      respect to the portion of such Optional Note Payment not so repaid (such
      compliance to be determined based on facts and circumstances in effect on
      the date the Company first made such Optional Note Payment); provided that
      any suit by or on behalf of the Company for the recovery of any such
      Optional Note Payment must be commenced within 2 years of the date such
      Optional Note Payment was first paid by the Company. Such repaid portion
      of such Optional Note Payment shall be held by the Company as if such
      repaid portion of such Optional Note Payment had never been made.

      12.3 Recapture Interest.

      Interest shall accrue at the interest rate provided in the Notes for
overdue payments of principal on each payment or prepayment of principal of the
Notes (and on all interest and Make-Whole Amount paid together with such
payment) that is repaid by any holder of Notes as provided in Section 12.1(c) or
Section 12.2(b) (such repaid amount referred to herein as the "Recaptured
Amount") from the date such payment was first paid by the Company to such holder
until the date when such Recaptured Amount, and the interest accrued at the
Default Rate, is finally, fully and indefeasibly paid by the Company to each
such holder. Upon such full, final and indefeasible payment, such holder shall
pay to the Company interest on such Recaptured Amount in respect of any period
when both the Default Rate applied to (and was indefeasibly paid to and
collected by such holder) such Recaptured Amount as provided in this Section
12.3 and such Recaptured Amount was in the possession of such holder, at the
federal funds overnight rate in effect from time to time during such period.

      12.4 Subordination of Obligations.

      The obligation of the Company under the Notes and this Agreement with
respect to the payment of outstanding principal of, interest on, and Make-Whole
Amount, if any, due with respect thereto, is and shall be fully and irrevocably
subordinate in right of payment and subject to the prior payment or provision
for payment in full of all claims of all other present and future creditors of
the Company arising out of any matter occurring prior to the date on which the
Company's obligation to make any such payment in respect of the Notes matures
consistent with the provisions hereof, except for

            (a) claims which are the subject of subordination provisions which
      rank on the same priority as the Notes or the class of claims of which the
      Notes are a member (claims hereunder shall rank pari passu with such
      claims), and


LaBranche & CO.                                          NOTE PURCHASE AGREEMENT
                                       35
<PAGE>

            (b) claims which are the subject of subordination provisions which
      rank junior to the Notes or the class of claims of which the Notes are a
      member (claims hereunder shall be senior to such claims),

provided that the rights of the holders of the Notes shall rank, now and in the
future, prior and superior to any claims represented by capital, equity or other
ownership interests of the Company, including, without limitation, claims of
general partners, limited partners, stockholders, and members, and claims
derived from such interests, including, without limitation, declared
distributions or dividends in respect of such interests, regardless of the
priority such claims would otherwise have under statute or law. Claims made
senior to the Notes pursuant to this Section 12.4 are referred to herein as
"Senior Claims".

      12.5 Certain Events.

      In the event of the appointment of a receiver or trustee of the Company or
in the event of its insolvency, liquidation pursuant to the SIPA or otherwise,
bankruptcy, assignment for the benefit of creditors, reorganization (whether or
not pursuant to bankruptcy laws) or any other marshalling of the assets and
liabilities of the Company, the obligation of the Company to pay the principal
of the Notes, together with interest accrued thereon and the Make-Whole Amount,
if any, due with respect thereto, shall become immediately due and payable- in
full (notwithstanding any contrary provision of this Agreement or the Notes) but
the holders of the Notes shall not be entitled to participate or share, ratably
or otherwise, in the distribution of assets of the Company in satisfaction of
such obligation to pay the principal of the Notes, together with the interest
accrued thereon and the Make-Whole Amount, if any, due with respect thereto,
until all Senior Claims have been fully satisfied (or provision made for payment
if assets of the Company available to pay the same shall be adequate in amount
to satisfy all such claims fully). Subject to the payment in full of all Senior
Claims, the holders of Notes shall be, to the extent of distributions of
property of the Company to the holders of Senior Claims to which the holders of
Notes would be entitled but for this Section 12, subrogated to the rights of the
holders of such Senior Claims.

      12.6 Obligations Not Impaired.

      Nothing contained in this Section 12 shall impair, as between the Company
and any holder of Notes, the obligation of the Company to pay to such holder the
principal of the Notes, interest thereon, Make-Whole Amount and any other
amounts, if any, due with respect thereto, as and when the same shall become due
and payable in accordance with the terms hereof to the extent that such payments
are made in compliance with Section 12.1 or Section 12.2, or require the holders
of the Notes to turn over any such payment to the Company except as provided in
Section 12.1(c) and Section 12.2(b), or subordinate the claims against the
Company of the holders of the Notes to any other Person except the holder of a
Senior Claim, and then only in connection with an Insolvency Event.

      12.7 Non-liability of NYSE.

      You warrant and represent that the Notes are not being purchased in
reliance upon the standing of the Company as a member organization of the NYSE
or upon the NYSE's surveillance of the Company's financial position or its
compliance with the Constitution, Rules and practices of the NYSE. You have made
such investigation of the Company and its members, partners, officers and
directors as you deem necessary and appropriate under the circumstances. You are
not relying upon the NYSE to provide any information concerning or relating to
the

                                       36
<PAGE>

Company and you agree that the NYSE has no responsibility to disclose to the
holders of the Notes any information concerning or relating to the Company which
it may now, or at any future time, have. Neither the NYSE, its Special Trust
Fund, nor any director, officer, trustee or employee of the NYSE or said Trust
Fund shall be liable to the holders of the Notes with respect to this Agreement
or the repayment the Notes or of any interest thereon or other amounts due with
respect thereto.

      12.8 Status of Proceeds of Notes.

      The proceeds of the Notes shall be dealt with in all respects as capital
of the Company, shall be subject to the risks of its business, and may be
deposited in an account or accounts in the Company's name in any bank or trust
company.

      12.9 Notices to NYSE.

      Whenever prior written notice to the NYSE is required pursuant to the
provisions of this Agreement, such written notice shall be given by the Company
to

      12.10 Futures Commission Merchants.

in the CEA, the Company agrees, consistent with the requirements of section
1.17(h) of the regulations of the CFTC (17 C.F.R. ss. 1.17(h)), that:

      CFTC and/or of the DSRO; and

            (c) whenever the Company receives written notice of acceleration of
      maturity pursuant to the provisions of this Agreement, the Company shall
      promptly give written notice thereof to the CFTC at the address above
      stated and to the DSRO, as required.

      12.11 Set-off.

      The holders of the Notes agree that they are not taking and will not take
or assert as security for the payment of the Notes any security interest in or
Lien upon, whether created by contract, statute or otherwise, any property of
the Company or any property in which the Company may have an interest, which is
or at any time may be in the possession or subject to the control of any holder
of Notes. The holders of the Notes hereby waive, and further agree that they
will not seek to obtain payment of the Notes in whole or in any part by
exercising, any right of set-off they may assert or possess in connection with,
and related to, the Notes, whether created by contract, statute or otherwise.
Any agreement between the Company and the holders of the Notes (whether in the
nature of a general loan and collateral agreement, a security or pledge
agreement or otherwise) shall be deemed amended hereby to the extent necessary
so as not to be inconsistent with the provisions of this Section 12.11.

the registration and registration of transfers of Notes. The name and address of
each holder of one or more Notes, each transfer thereof and the name and address
of each transferee of one or more Notes shall be registered in such register.
Prior to due presentment for registration of transfer, the Person in whose name
any Note shall be registered shall be deemed and treated as the owner and holder

complete and correct copy of the names and addresses of all registered holders
of Notes.

      13.2 Transfer and Exchange of Notes.

for registration of transfer, duly endorsed or accompanied by a written

his attorney duly authorized in writing and accompanied by the address for
notices of each transferee of such Note or part thereof), the Company shall
execute and deliver, at the Company's expense (except as provided below), one or
more new Notes (as requested by the holder thereof) in exchange therefor, in an
aggregate principal amount equal to the unpaid principal amount of the
surrendered Note. Each such new Note shall be payable to such Person as such
holder may request and shall be substantially in the form of Exhibit 1. Each
such new Note shall be dated and bear interest from the date to which interest
shall have been paid on the surrendered Note or dated the date of the
surrendered Note if no interest shall have been paid thereon. The Company may

its nominee), shall be deemed to have made the representation set forth in
Section 6.2.

      13.3 Limitation on Transfer of Notes.

      No holder of Notes may, without the prior written consent of the Company,
transfer its Notes to a Competitor or an affiliate of a Competitor. The Company

law or regulation.

      13.4 Replacement of Notes.

such Institutional Investor of such ownership and such loss, theft, destruction
or mutilation), and

      is, or is a nominee for, a Purchaser or another holder of a Note with a
      minimum net worth of at least $50,000,000, such Person's own unsecured
      agreement of indemnity shall be deemed to be satisfactory), or

            (b) in the case of mutilation, upon surrender and cancellation
      thereof,

the Company at its own expense shall execute and deliver, in lieu thereof, a new
Note, dated and bearing interest from the date to which interest shall have been
paid on such lost, stolen, destroyed or mutilated Note or dated the date of such
lost, stolen, destroyed or mutilated Note if no interest shall have been paid

a bank or trust company in such jurisdiction.

any Note, you shall surrender such Note for cancellation, reasonably promptly
after any such request, to the Company at its principal executive office or at
the place of payment most recently designated by the Company pursuant to Section

      cause to be paid any remuneration, whether by way of supplemental or
      additional interest, fee or otherwise, or grant any security, to any
      holder of Notes as consideration for or as an inducement to the entering
      into by any holder of Notes of any waiver or amendment of any of the terms
      and provisions hereof unless such remuneration is concurrently paid, or
      security is concurrently granted, on the same terms, ratably to each
      holder of Notes then outstanding even if such holder did not consent to
      such waiver or amendment.

      17.3  Binding Effect, etc.

      Any amendment or waiver consented to as provided in this Section 17
applies equally to all holders of Notes and is binding upon them and upon each
future holder of any Note and upon the Company without regard to whether such
Note has been marked to indicate such amendment or waiver. No such amendment or
waiver will extend to or affect any obligation, covenant, agreement, Default,
Event of Default or Event of Acceleration not expressly amended or waived or
impair any right consequent thereon. No course of dealing between the Company
and the holder of any Note nor any delay in exercising any rights hereunder or
under any Note shall operate as a waiver of any rights of any holder of such
Note. As used herein, the term "this Agreement" and references thereto shall
mean this Agreement as it may from time to time be amended or supplemented.

      17.4  Notes held by Company, etc.

      Solely for the purpose of determining whether the holders of the requisite
percentage of the aggregate principal amount of Notes then outstanding approved
or consented to any amendment, waiver or consent to be given under this
Agreement or the Notes, or have directed the taking of any action provided
herein or in the Notes to be taken upon the direction of the holders of a
specified percentage of the aggregate principal amount of Notes then
outstanding, Notes directly or indirectly owned by the Company or any of its
Affiliates shall be deemed not to be outstanding.

18.   NOTICES

      All notices and communications provided for hereunder shall be in writing

            (a) by telecopy if the sender on the same day sends a confirming
      copy of such notice by a recognized overnight delivery service (charges
      prepaid),

            (b) by registered or certified mail with return receipt requested
      (postage prepaid), or

            (c) by a recognized overnight delivery service (with charges
      prepaid).

      the beginning hereof to the attention of George M.L. LaBranche, IV, or at
      such other address as the Company shall have specified to the holder of
      each Note in writing.

Notices under this Section 18 will be deemed given only when actually received.

19.   REPRODUCTION OF DOCUMENTS

      This Agreement and all documents relating thereto, including, without
limitation,

            (a) consents, waivers and modifications that may hereafter be
      executed,

            (b) documents received by you at the Closing (except the Notes
      themselves), and

            (c) financial statements, certificates and other information
      previously or hereafter furnished to you,

may be reproduced by you by any photographic, photostatic, microfilm, microcard,
miniature photographic or other similar process and you may destroy any original
document so reproduced. The Company agrees and stipulates that, to the extent
permitted by applicable law, any such reproduction shall be admissible in
evidence as the original itself in any judicial or administrative proceeding
(whether or not the original is in existence and whether or not such
reproduction was made by you in the regular course of business) and any
enlargement, facsimile or further reproduction of such reproduction shall
likewise be admissible in evidence. This Section 19 shall not prohibit the
Company or any other holder of Notes from contesting any such reproduction to
the same extent that it could contest the original, or from introducing evidence
to demonstrate the inaccuracy of any such reproduction.

20.   CONFIDENTIAL INFORMATION

      For the purposes of this Section 20, "Confidential Information" means
information delivered to you by or on behalf of the Company in connection with
the transactions contemplated by or otherwise pursuant to this Agreement that is
proprietary in nature and that was clearly marked or labeled or otherwise
adequately identified when received by you as being confidential information of
the Company, provided that such term does not include information that

            (a) was publicly known or otherwise known to you prior to the time
      of such disclosure,

            (b) subsequently becomes publicly known through no act or omission
      by you or any Person acting on your behalf,

            (c) otherwise becomes known to you other than through disclosure by
      the Company, or

            (d) constitutes financial statements delivered to you under Section
      7.1 that are otherwise publicly available.

You will maintain the confidentiality of such Confidential Information in
accordance with procedures adopted by you in good faith to protect confidential
information of third parties delivered to you, provided that you may deliver or
disclose Confidential Information to

            (i) your directors, officers, trustees, employees, agents, attorneys
      and affiliates, (to the extent such disclosure reasonably relates to the
      administration of the investment represented by your Notes),


LaBranche & CO.                        43                NOTE PURCHASE AGREEMENT
<PAGE>

            (ii) your financial advisors and other professional advisors who
      agree to hold confidential the Confidential Information substantially in
      accordance with the terms of this Section 20,

            (iii) any other holder of any Note,

            (iv) any Institutional Investor to which you sell or offer to sell
      such Note or any part thereof or any participation therein (if such Person
      has agreed in writing prior to its receipt of such Confidential
      Information to be bound by the provisions of this Section 20),

            (v) any Person from which you offer to purchase any security of the
      Company (if such Person has agreed in writing prior to its receipt of such
      Confidential Information to be bound by the provisions of this Section
      20),

            (vi) any federal or state regulatory authority having jurisdiction
      over you,

            (vii) the National Association of Insurance Commissioners or any
      similar organization, or any nationally recognized rating agency that
      requires access to information about your investment portfolio, or

            (viii) any other Person to which such delivery or disclosure may be
      necessary or appropriate

                  (A) to effect compliance with any law, rule, regulation or
            order applicable to you,

                  (B) in response to any subpoena or other legal process,

                  (C) in connection with any litigation to which you are a party
            or

                  (D) if an Event of Default or an Event of Acceleration has
            occurred and is continuing, to the extent you may reasonably
            determine such delivery and disclosure to be necessary or
            appropriate in the enforcement or for the protection of the rights
            and remedies under your Notes and this Agreement.

Each holder of a Note, by its acceptance of a Note, will be deemed to have
agreed to be bound by and to be entitled to the benefits of this Section 20 as
though it were a party to this Agreement. On reasonable request by the Company
in connection with the delivery to any holder of a Note of information required
to be delivered to such holder under this Agreement or requested by such holder
(other than a holder that is a party to this Agreement or its nominee), such
holder will enter into an agreement with the Company embodying the provisions of
this Section 20.

21.   SUBSTITUTION OF PURCHASER

      You shall have the right to substitute any one of your Affiliates as the
purchaser of the Notes that you have agreed to purchase hereunder, by written
notice to the Company, which notice shall be signed by both you and such
Affiliate, shall contain such Affiliate's agreement to be bound by this
Agreement and shall contain a confirmation by such Affiliate of the accuracy
with respect to it of the representations set forth in Section 6. Upon receipt
of such notice, wherever the word "you" is used in this Agreement (other than in
this Section 21), such word shall


LaBranche & CO.                        44                NOTE PURCHASE AGREEMENT
<PAGE>

be deemed to refer to such Affiliate in lieu of you. In the event that such
Affiliate is so substituted as a purchaser hereunder and such Affiliate
thereafter transfers to you all of the Notes then held by such Affiliate, upon
receipt by the Company of notice of such transfer, wherever the word "you" is
used in this Agreement (other than in this Section 21), such word shall no
longer be deemed to refer to such Affiliate, but shall refer to you, and you
shall have all the rights of an original holder of the Notes under this
Agreement.

22.   MISCELLANEOUS

      22.1  Successors and Assigns.

      All covenants and other agreements contained in this Agreement by or on
behalf of any of the parties hereto bind and inure to the benefit of their
respective successors and assigns (including, without limitation, any subsequent
holder of a Note) whether so expressed or not.

      22.2  Payments Due on Non-Business Days.

      Anything in this Agreement or the Notes to the contrary notwithstanding,
any payment of principal of or Make-Whole Amount or interest on any Note that is
due on a date other than a Business Day shall be made on the next succeeding
Business Day without including the additional days elapsed in the computation of
the interest payable on such next succeeding Business Day.

      22.3  Severability.

      Any provision of this Agreement that is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or
render unenforceable such provision in any other jurisdiction.

      22.4  Construction.

      Each covenant contained herein shall be construed (absent express
provision to the contrary) as being independent of each other covenant contained
herein, so that compliance with any one covenant shall not (absent such an
express contrary provision) be deemed to excuse compliance with any other
covenant. Where any provision herein refers to action to be taken by any Person,
or which such Person is prohibited from taking, such provision shall be
applicable whether such action is taken directly or indirectly by such Person.

      22.5  Counterparts.

      This Agreement may be executed in any number of counterparts, each of
which shall be an original but all of which together shall constitute one
instrument. Each counterpart may consist of a number of copies hereof, each
signed by less than all, but together signed by all, of the parties hereto.

the Borrower shall pay to the Bank, on or prior to the [ILLEGIBLE] Commitment,
the unpaid principal amount of the Note in full, [ILLEGIBLE] thereon to the date
of such payment and all fees and other amounts [ILLEGIBLE] and under the other
Loan Documents.

      Section 2.4. Increase of Commitment.

            If, after the date hereof, the NYSE allocates to the Borrower the
right to make a market as a specialist (pursuant to the rules and regulations of
the NYSE) in any additional security listed on the NYSE, the Borrower shall have
the option (the "Option"), exercisable once during the term of this Agreement,
to increase the Commitment by an amount which is equal to or less than 10% of
the Commitment immediately prior to the Borrower's exercise


                                      -7-
<PAGE>

of the Option. If the Borrower desires to exercise the Option, it shall give the
Bank at least three (3) Business Days' prior irrevocable written or fax notice
of its intention to exercise the Option, which notice (a) shall specify the date
(which shall be a Business Day on or after the day on which such allocation
becomes effective) on which the Commitment is to be increased and the amount of
the increase in the Commitment, and (b) shall be accompanied by (i) evidence
satisfactory to the Bank and its counsel of such allocation by the NYSE (which
evidence shall indicate the date of effectiveness of such allocation) and (ii)
if the Borrower has theretofore executed and delivered to the Bank a Note, a new
Note, duly executed by the Borrower, in the amount of the increased Commitment.

      Section 2.5. Use of Proceeds.

            The proceeds of the Loans shall be used by the Borrower (a) to
finance the specialist security positions of the Borrower, (b) to finance the
"purchasing" or "carrying" by the Borrower of "margin stock" other than
specialist security positions (the terms "purchasing", "carrying" and "margin
stock" being as defined in Regulation U promulgated by the Board of Governors of
the Federal Reserve System) or (c) to reduce or retire a Loan outstanding
hereunder.

      Section 2.6. Commitment Fee.

            The Borrower shall pay to the Bank on the last Business Day of each
calendar quarter, commencing on the first such day following the date hereof, a
commitment fee at the rate of .28125% per annum (calculated on the basis of a
360 day year for the actual number of days involved) on the average daily unused
amount of the Commitment during the quarter (or portion thereof) ending on the
date such payment is due. Any such fee payable with respect to the quarter in
which the Commitment is terminated pursuant to Section 2.3(a)(i), 2.3(b) or 6.1
hereof shall be paid on the date of such termination.

      Section 2.7. Interest.

            Each Loan shall bear interest at a rate per annum equal to the
Broker Rate, but in no event in excess of the maximum rate permitted by law.
Interest shall be payable (a) monthly on the last Business Day of each month,
commencing on the last Business Day of the month in which the initial Loan is
made, and (b) at maturity. Notwithstanding the foregoing, all principal payments
due on Loans which are in default shall bear interest, payable on demand, from
the date of default until paid (whether before or after judgment) at a rate per
annum equal to the Broker Rate plus two percent (2%). Interest shall be
calculated on the basis of a 360 day year for the actual number of days
involved. The interest rate shall change on the effective date of any change in
the Broker Rate; provided, however, that the Bank shall have no obligation to
notify the Borrower of such change in the Broker Rate.

      Section 2.8. Repayments; Rollovers.

            (a) Except as otherwise provided herein, each Loan shall be repaid
by the Borrower before the Close of Business on such Loan's Maturity Date.
Notwithstanding the foregoing sentence, and provided that no Default or Event of
Default exists or would exist after giving effect thereto, the Borrower may
request that a Loan be rolled over until not later than the Close of Business on
the Business Day immediately succeeding the Maturity Date of such Loan by giving
the Bank an irrevocable request therefor not later than one hour prior to


                                      -8-
<PAGE>

the Close of Business on such Maturity Date. As promptly as practicable after
the Bank decides, in its sole and absolute discretion, to roll over such Loan,
the Bank shall give telephonic notice to such effect to the Borrower and the
Maturity Date of such Loan shall be extended to the Close of Business on the
immediately succeeding Business Day. Under no circumstance, however, will the
Bank be obligated to roll over a Loan, even if the Collateral Value therefor is
or is made sufficient pursuant to Section 2.8 (b) or (c), and the fact that a
Loan has been rolled over shall not obligate the Bank to do so again and if for
any reason or no reason a Loan is not rolled over, such Loan shall be due and
payable by the Close of Business on its Maturity Date. As used in this Section,
the term "rolled over" shall mean the making of a Loan the proceeds of which
shall be used to repay the Loan made to the Borrower on the immediately
preceding Business Day.

            (b) If, at any time, whether on or after a Borrowing Date, the
      outstanding principal balance of all Specialist Loans shall exceed the
      Specialist Borrowing Base, the Borrower shall repay the Specialist Loans
      in a sufficient amount (together with accrued interest on the amount
      repaid to the date of repayment) such that, after giving effect to such
      repayment, the outstanding principal balance of all Specialist Loans does
      not exceed the Specialist Borrowing Base; provided, however, that in lieu
      of making all or part of such repayment, the Borrower may, pursuant to the
      Security Agreement, grant to the Bank a security interest in and lien upon
      a sufficient number of Specialist Securities which are not, immediately
      prior to such grant, part of the Collateral such that, after giving effect
      to such grant and any simultaneous repayment of the Specialist Loans, the
      aggregate outstanding principal balance of the Specialist Loans does not
      exceed the Specialist Borrowing Base.

            (c) If, at any time, whether on or after a Borrowing Date, the
      outstanding principal balance of all Non-Specialist Loans shall exceed the
      Non-Specialist Borrowing Base, the Borrower shall repay the Non-Specialist
      Loans in a sufficient amount (together with accrued interest on the amount
      repaid to the date of repayment) such that, after giving effect to such
      repayment, the outstanding principal balance of all Non-Specialist Loans
      does not exceed the Non-Specialist Borrowing Base; provided, however, that
      in lieu of making all or part of such repayment, the Borrower may,
      pursuant to the Security Agreement, grant to the Bank a security interest
      in and lien upon a sufficient number of Non-Specialist Securities which
      are not, immediately prior to such grant, part of the Collateral such
      that, after giving effect to such grant and any simultaneous repayment of
      the Non-Specialist Loans, the aggregate outstanding principal amount of
      the Non-Specialist Loans does not exceed the NonSpecialist Borrowing Base.

            (d) Each determination by the Bank of the Non-Specialist Borrowing
      Base, the Specialist Borrowing Base and the Collateral Value shall be
      conclusive absent manifest error.

      Section 2.9. Payments.

            All payments hereunder, under the Note and under the other Loan
Documents shall be made in federal or other immediately available funds. The
Bank is hereby authorized to charge the Borrower's deposit account maintained at
the Bank for each payment of interest and fees due hereunder and under the Note.
If any payment under this Agreement or any other Loan Document becomes due and
payable on a day other than a Business Day,


                                      -9-
<PAGE>

the date of such payment shall be extended to the next succeeding Business Day,
and interest thereon (to the extent permitted by law) shall be payable for the
extended time.

      Section 2.10. Capital Adequacy.

            (a) In the event that the Bank shall have determined that any
applicable law, rule, regulation or guideline regarding capital adequacy, or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Bank (or any
lending office of the Bank) with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on the Bank's capital as a consequence of its obligations hereunder to a
level below that which the Bank could have achieved but for such adoption,
change or compliance (taking into consideration the Bank's policies with respect
to capital adequacy) by an amount reasonably deemed by the Bank to be material,
then, from time to time, the Borrower shall pay upon demand to the Bank such
additional amount or amounts as will compensate the Bank for such reduction. In
determining such amount or amounts, the Bank may use any reasonable averaging
and attribution methods. The protection of this Section 2.10 shall be available
to the Bank regardless of any possible contention of invalidity or
inapplicability of the law, regulation or condition which shall have been
imposed.

            (b) A certificate of the Bank setting forth such amount or amounts
as shall be necessary to compensate the Bank as specified in Section 2.10(a)
hereof shall be delivered to the Borrower and shall be conclusive absent
manifest error.

            (c) The obligations of the Borrower under Section 2.10(a) hereof
shall survive termination of the Commitment, this Agreement and the other Loan
Documents and payment of the Note and all Loans.

                                 AMENDMENT NO. 1

      AMENDMENT NO. 1 (this "Amendment"), dated as of June 23, 1999, to the
Credit Agreement (the "Credit Agreement") dated as of June 26, 1998, and to the
Security Agreement (the "Security Agreement") executed and delivered therewith,
each by and among LaBranche & Co., a New York limited partnership (the
"Borrower") and The Bank of New York, (the "Bank")

                                    RECITALS

      I. Capitalized terms used herein which are not otherwise defined herein
shall have the respective meanings ascribed thereto in the Credit Agreement.

      II. The Borrower has requested that the Credit Agreement be amended to the
extent and in the manner set forth below and the Bank is agreeable to such
amendment subject to the terms and conditions hereof.

      Accordingly, in consideration of the terms and conditions hereinafter set
forth, and for other good and valuable consideration, the receipt and adequacy
of which are hereby acknowledged, the parties hereto agree as follows:

      1. Section 1.3 of the Credit Agreement is amended by restating in their
entirety the following definitions:

      "Commitment" shall mean $100,000,000, as the same may be (a) reduced from
time to time pursuant to Section 2.3(a)(ii) hereof and/or increased pursuant to
Section 2.4 hereof.

      "Special Counsel" shall mean Bryan Cave LLP.

      "Termination Date" shall mean June 23, 2000.

      2. Section 3.1 is amended by adding the following subsection at the end
thereof:

            (u) Year 2000. Any reprograniming required to permit the proper
functioning, in and following the year 2000, of (i) the Borrower's computer
systems and (ii) equipment containing embedded microchips (including systems and
equipment supplied by others or with which the Borrower's systems interact) and
the testing of all such systems and equipment, as so reprogrammed, is expected
to be completed in October of 1999. The cost to the Borrower of such
reprogramming and testing and of the reasonably foreseeable consequences of year
2000 to the Borrower (including


                                      1 -
<PAGE>

reprogramming errors and the failure of others' systems or equipment) is not
expected to result in a Default or have a material adverse effect on the
business, prospects, operations, properties, assets or condition (financial or
otherwise) of the Borrower. Except for such of the reprogramming referred to in
the preceding sentence as may be necessary, the computer and management
information systems of the Borrower are and, with ordinary course upgrading and
maintenance, are expected to continue for the term of this Credit Agreement to
be, sufficient to permit the Borrower to conduct its business as presently
conducted without a material adverse change in the business, prospects,
operations, properties, assets or condition (financial or otherwise) of the
Borrower.

      3. Section 5.1 of the Credit Agreement is amended to restate in their
entirety subsections (a) and (b) thereof as follows:

      (a)   Net Capital. Maintain at all times a net capital (as defined in Rule
            15c3-1(c)(2) promulgated by the SEC) of not less than $75,000,000.

      (b)   Net Worth. Maintain at all times a net worth (computed as required
            for reporting on item 5, line 3530 of a FOCUS Report of the
            Borrower) of not less than $100,000,000.

      4. Schedule 3.1(d) is amended in its entirety to read as set forth in
Schedule 3.1(d) attached hereto.

      5. The date contained in the third line of the first paragraph of the
Security Agreement is amended to read "June 26, 1998".

      6. This Amendment shall not be effective until such date as the Borrower
and the Bank shall have executed and delivered this Amendment.

      7. On and as of the date hereof the Borrower hereby (a) reaffirms and
admits the validity and enforceability of the Loan Documents and all of its
obligations thereunder, (b) agrees and admits that it has no defenses to or
offsets against any such obligation, (c) represents and warrants that no Default
has occurred and is continuing, and that each of the representations and
warranties made by it in the Loan Documents is true and correct with the same
effect as though such representation and warranty had been made on such date,
and (d) agrees to pay the reasonable fees and disbursements of Special Counsel
in connection with this Amendment.

      8. In all other respects, the Loan Documents shall remain in full force
and effect, and no amendment in respect of any term or condition of any Loan
Document contained


                                      2 -
<PAGE>

herein shall be deemed to be an amendment in respect of any other term or
condition contained in any Loan Document.

      9. This Amendment may be executed in any number of counterparts all of
which, taken together, shall constitute one amendment. In making proof of this
Amendment, it shall only be necessary to produce the counterpart executed and
delivered by the party to be charged.

      10. THIS AMENDMENT IS BEING EXECUTED AND DELIVERED IN, AND IS INTENDED
TO BE PERFORMED IN, THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCEABLE
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK OTHER THAN THOSE RELATING
TO CONFLICT OF LAWS.

                            INDEMNIFICATION AGREEMENT

          THIS INDEMNIFICATION AGREEMENT (this "AGREEMENT") is made and entered
into as of the ___ day of ______ 1999, by and between LaBranche & Co Inc., a
Delaware corporation (the "COMPANY") and each of the Indemnitees listed on the
signature pages to this agreement (each, an "INDEMNITEE", and collectively, the
"INDEMNITEES") as such signature pages may be amended and supplemented from time
to time.

                               W I T N E S S E T H

          WHEREAS, the Company has become party to (i) a Plan of Incorporation
dated as of June ___, 1999, (the "PLAN OF INCORPORATION") and (ii) an Exchange
Agreement, dated as of June ___, 1999 (the "EXCHANGE AGREEMENT") (such Plan of
Incorporation, together with all exhibits thereto, and such Exchange Agreement,
together with all exhibits thereto, as each may be amended from time to time,
the "TRANSACTION DOCUMENTS");

          WHEREAS, as part of the Transaction Documents, the Company has filed a
registration statement (the "REGISTRATION STATEMENT") with the Securities and
Exchange Commission for the public offering and sale of shares of its common
stock (including shares issuable in connection with employee benefit plans);

          WHEREAS, the Company has requested and will request certain of the
Indemnitees to execute the Registration Statement in the capacity or capacities
listed and to be listed in such Registration Statement; and

          WHEREAS, each Indemnitee is one or more of the following: (i) an
officer or director of the Company or (ii) a person requested or authorized by
the board of directors of the Company or the Managing Committee of LaB Investing
Co. L.L.C., a New York limited liability company ("INVESTING") to take actions
on behalf of the Company, Investing or LaBranche & Co., a New York limited
partnership, in connection with the Registration Statement or any of the
Transaction Documents.

          NOW, THEREFORE, in consideration of each Indemnitee's acting and
agreeing to act in the capacities referred to above, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties do hereby agree as follows:

          Section 1. GENERAL. The Company (A) will indemnify and hold harmless
each Indemnitee against any Losses (as hereinafter defined), joint or several,
to which such Indemnitee may become subject, under the Securities Act of 1933,
as amended (the "ACT") or otherwise, insofar as such Losses (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in the Registration


<PAGE>

Statement or any related Rule 462(b) Registration Statement or any preliminary
prospectus or prospectus comprising a part thereof, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; provided, however, that
the Company shall not be liable in any such case to the extent that any such
Losses arise out of or are based upon an untrue statement or alleged untrue
statement or omission or alleged omission relating to such Indemnitee made in
any preliminary prospectus, any registration statement or any prospectus or any
amendment or supplement in reliance upon and in conformity with written
information relating to such Indemnitee furnished to the Company by such
Indemnitee expressly for use therein; and (B) will indemnify and hold harmless
each Indemnitee against any Losses (or actions in respect thereof) which
otherwise arise out of or are based upon or asserted against such Indemnitee in
connection with such Indemnitee's acting in the capacities referred to above in
connection with the transactions contemplated by the Transaction Documents,
except to the extent any such Losses referred to in this clause (B) arise out of
or are based upon the type of conduct for which (x) a director would not be
exempt from liability or (y) the indemnification of a director would be limited
in respect of such Losses, in the case of (x) and (y), within the meaning of
Article Tenth of the Amended and Restated Certificate of Incorporation of the
Company or Section 102(b)(7) of the Delaware General Corporation Law (whether or
not such Indemnitee is a director).

          Notwithstanding the foregoing provisions of this Section 1, the
Company and each Indemnitee agree that insofar as indemnification for
liabilities arising under the Act may be permitted under this Agreement to an
Indemnitee who is a director, officer or controlling person of the Company, in
the event that a claim for indemnification against such liabilities is made by
such an Indemnitee (other than the payment by the Company of expenses incurred
or paid by such Indemnitee in the successful defense of any action, suit or
proceeding) in connection with a Registration Statement, the Company will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act, and
the Company and such Indemnitee will be governed by the final adjudication of
such question.

          Section 2. LOSSES. As used in this Agreement, the term "LOSSES" shall
include, without limitation, damages, losses, claims, judgments, liabilities,
fines, penalties, excise taxes, settlements, and costs, attorneys' fees,
accountants' fees, and disbursements and costs of attachment or similar bonds,
investigation costs, defense preparation costs, costs of preparing for and
presenting evidence or testimony, and any expenses of establishing a right to
indemnification under this Agreement. The term "Losses" shall not include taxes,
except to the extent taxes are imposed in respect of payments otherwise made
pursuant to this Agreement, in which case such Indemnitee's Losses shall include
an amount not greater than the net taxes payable (taking into account any
deductions or other tax benefits available to such Indemnitee as a result of the
Losses in respect of which such payment is made).

          Section 3. ENFORCEMENT. Subject to the provisions of the second
paragraph of Section 1 hereof, if a claim or request by an Indemnitee under this
Agreement is not paid by the

                                      -2-
<PAGE>

Company, or on its behalf, within thirty days after a written claim of request
has been received by the Company and, if applicable, the affirmation in Section
6 hereof has been received by the Company, such Indemnitee may at any time
thereafter commence an arbitration proceeding in accordance with Section 9
hereof against the Company to recover the unpaid amount of the claim or request
and, if successful in whole or in part, such Indemnitee shall also be entitled
to be paid the expenses of prosecuting such proceeding. It shall be a defense to
any such proceeding (other than a proceeding commenced to enforce a claim for
expenses incurred in defending any actual or threatened proceeding in advance of
its final disposition where the required affirmation and undertaking, if any is
required, have been tendered to the Company) that such Indemnitee has not met
the standards of conduct for the Company to indemnify such Indemnitee herein for
the amount claimed, but the burden of proving such defense shall be on the
Company. Neither the failure of the Company (including its board of directors,
legal counsel or shareholders) to have made a determination prior to the
commencement of such proceeding that indemnification of such Indemnitee is
proper in the circumstances because such Indemnitee has met the applicable
standard of conduct set forth herein, nor an actual determination by the Company
(including its board of directors, legal counsel or shareholders) that such
Indemnitee has not met such applicable standard of conduct, shall be a defense
to the proceeding or create a presumption that such Indemnitee has not met the
applicable standard of conduct.

          Section 4. PARTIAL INDEMNIFICATION. If an Indemnitee is entitled under
any provision of this Agreement to indemnification by the Company for some or a
portion of any Losses, but not for the total amount thereof, the Company shall
nevertheless indemnify such Indemnitee for the portion of such losses to which
such Indemnitee is entitled.

          Section 5. EXPENSES. Expenses incurred by an Indemnitee in connection
with any proceeding shall be paid by the Company upon request of such Indemnitee
that the Company pay such expenses, but only upon receipt by the Company of (i)
a written affirmation of such Indemnitee's good faith belief that the applicable
standard of conduct necessary for indemnification by the Company has been met,
(ii) a written undertaking by or on behalf of such Indemnitee to reimburse the
Company for expenses if and to the extent that it is ultimately determined that
the applicable standard of conduct has not been met and (iii) satisfactory
evidence of the amount of such expenses.

          Section 6. NOTICE OF CLAIM. Each Indemnitee shall promptly notify the
Company in writing of any claim against such Indemnitee for which
indemnification will or could be sought under this Agreement. In addition, each
Indemnitee shall give the Company such information and cooperation as it may
reasonably require and as shall be within such Indemnitee's power and at such
times and places as are not unduly burdensome for such Indemnitee.

          Section 7. DEFENSE OF CLAIM. With respect to any proceeding as to
which an Indemnitee notifies the Company of the commencement thereof:

          (a) the Company will be entitled to participate at its own expense;

                                       -3-

<PAGE>

          (b) subject to Section 7(c) hereof, the Company shall not, in
     connection with any proceeding or related proceedings in the same
     jurisdiction against any Indemnitee and any other Indemnitees, be liable to
     such Indemnitee and such other Indemnitees for the fees and expenses of
     more than one separate law firm (in addition to a single firm of local
     counsel);

          (c) except as otherwise provided below, to the extent that it may
     wish, the Company will be entitled to assume the defense thereof, with
     counsel reasonably satisfactory to such Indemnitee, which in the Company's
     sole discretion may be regular counsel to the Company and may be counsel to
     other Indemnitees. The Indemnitees also shall have the right to employ one
     separate counsel for such Indemnitees in such action, suit or proceeding if
     such Indemnitees reasonably conclude that if they did not there would be a
     conflict of interest between the Company and such Indemnitees, and under
     such circumstances the fees and expenses of such counsel shall be paid by
     the Company; and

          (d) the Company shall not be liable to indemnify an Indemnitee under
     this Agreement for any amounts paid in settlement of any action or claim
     effected without the Company's written consent. The Company shall not
     settle any action or claim in any manner which would impose any cost or
     limitation on an Indemnitee without such Indemnitee's written consent.
     Neither the Company nor an Indemnitee will unreasonably withhold or delay
     its consent to any proposed settlement.

          Section 8. NON-EXCLUSIVITY. The right to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this Agreement shall not be exclusive of or affected in
any way by any other right which an Indemnitee may have or hereafter may acquire
under any statute, certificate of incorporation, bylaws, agreement, arrangement,
resolution or instrument providing indemnification or expense payment, except
that any payments otherwise required to be made by the Company hereunder shall
be offset by any and all amounts received by an Indemnitee from any other
indemnitor or under one or more liability insurance policies maintained by an
indemnitor or otherwise and shall not be duplicative of any other payments
received by an Indemnitee from the Company in respect of the matter giving rise
to the indemnity hereunder. When an Indemnitee is entitled to indemnification,
expense advancement or reimbursement under this Agreement and any other
agreement, arrangement, resolution or instrument of the Company, the Indemnitee
may choose to pursue its rights under one or more, but less than all, of such
applicable agreements, arrangements, resolutions or instruments, in which case
such Indemnitee need only comply with the standards and procedures of the
agreements, arrangements, resolutions or instruments under which it chooses to
pursue its rights.

          Section 9. ARBITRATION. (a) Subject to the provisions of the second
paragraph of Section 1 and Section 9(b) hereof, any dispute, controversy or
claim between an Indemnitee and the Company arising out of or relating to or
concerning the provisions of this Agreement shall be finally settled by
arbitration in New York City before, and in accordance with

                                      -4-
<PAGE>

the rules then obtaining of, the New York Stock Exchange, Inc. ("NYSE") or, if
the NYSE declines to arbitrate the matter, the American Arbitration Association
(the "AAA") in accordance with the commercial arbitration rules of the AAA.

          (b) Notwithstanding the provisions of Section 9(a) and in addition to
its right to submit any dispute or controversy to arbitration, the Company may
bring an action or special proceeding in a state or federal court of competent
jurisdiction sitting in the State of New York, whether or not an arbitration
proceeding has theretofore been or is ever initiated, for the purpose of
temporarily, preliminarily or permanently enforcing the provisions of this
Agreement or to enforce an arbitration award, and, for the purposes of this
Section 9(b), each Indemnitee (i) expressly consents to the application of
Section 9(c) hereof to any such action or proceeding, (ii) agrees that proof
shall not be required that monetary damages for breach of the provisions of this
Agreement would be difficult to calculate and that remedies at law would be
inadequate and (iii) irrevocably appoints the Secretary of the Company, One
Exchange Plaza, New York, New York 10006 as such Indemnitee's agent for service
of process in connection with any such action or proceeding, who shall promptly
advise such Indemnitee of any such service of process.

          (c) (i) EACH INDEMNITEE HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE
JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED IN THE STATE OF NEW YORK OVER
ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO OR CONCERNING THIS
AGREEMENT THAT IS NOT OTHERWISE ARBITRATED ACCORDING TO THE PROVISIONS OF
SECTION 9(a) HEREOF. This includes any suit, action or proceeding to compel
arbitration or to enforce an arbitration award. The parties acknowledge that the
forum designated by this Section 9(c) has a reasonable relation to this
Agreement, and to the parties' relationship with one another. Notwithstanding
the foregoing, nothing herein shall preclude the Company from bringing any
action or proceeding in any other court for the purpose of enforcing the
provisions of this Section 9.

              (ii) The agreement of an Indemnitee as to forum is independent of
the law that may be applied in the action, and each Indemnitee agrees to this
forum even if the forum may under applicable law choose to apply non-forum law.
Each Indemnitee hereby waives, to the fullest extent permitted by applicable
law, any objection which such Indemnitee now or hereafter may have to personal
jurisdiction or to the laying of venue of any such suit, action or proceeding in
any court referred to in section 9(c)(i). The parties undertake not to commence
any action arising out of or relating to this Agreement in any forum other than
the forum described in this Section 9(c). The parties agree that, to the fullest
extent permitted by applicable law, a final and non-appealable judgment in any
such suit, action or proceeding in any such court shall be conclusive and
binding upon the parties.

          Section 10. BINDING EFFECT. This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the parties hereto and their
respective successors, assigns (including any direct or indirect successor by
merger or consolidation), heirs, executors and administrators.

                                       -5-

          Section 11. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD
TO PRINCIPLES OF CONFLICTS OF LAWS.

          Section 12. AMENDMENT. Each party understands that from time to time
certain other persons may become Indemnitees and certain Indemnitees will cease
to be Indemnitees to the extent provided in this Section 12. Accordingly, this
Agreement may be amended by action of the Company from time to time to add
additional Indemnitees, without the approval of any other person other than such
proposed Indemnitees, each of whom shall execute a counterpart of the signature
page of this Agreement. This Agreement may also be amended by action of the
Company and without the approval of any other person to remove an Indemnitee;
provided that such amendment shall not be effective unless the Company has
provided 30 days prior written notice to the Indemnitee and, in any event, such
amendment shall not affect any rights of such Indemnitee to be indemnified in
respect of Losses associated with the acts, omissions or status of such
Indemnitee through the effective date of such amendment (including the right to
subsequent indemnification and expense advancement and reimbursement relating to
such acts, omissions or status).

          Section 13. WAIVER OF BREACH. The failure or delay of a party at any
time to require performance by any other party of any provision of this
Agreement, even if known, shall not affect the right of such party to require
performance of that provision or to exercise any right, power, or remedy
hereunder, and any waiver by any party of any breach of any provision of this
Agreement shall not be construed as a waiver of any continuing or succeeding
breach of such provision, a waiver of the provision itself, or a waiver of any
right, power, or remedy under this Agreement. No notice to or demand on any
party in any case shall, of itself, entitle such party to other or further
notice or demand in similar or other circumstances.

          Section 14. SEVERABILITY. The Company and each Indemnitee agree that
the agreements and provisions contained in this Agreement are severable and
divisible, that each such agreement and provision does not depend upon any other
provision or agreement for its enforceability, and that each such agreement and
provision set forth herein constitutes an enforceable obligation between the
Company and such Indemnitee. Consequently, the Company and each Indemnitee
agrees that neither the invalidity nor the unenforceability of any provision of
this Agreement shall affect the other provisions hereof, and this Agreement
shall remain in full force and effect and be construed in all respects as if
such invalid or unenforceable provision were omitted.

          Section 15. NO PRESUMPTION. The termination of any action, suit or
proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent, shall not, of itself, create a presumption that an
Indemnitee did not meet the applicable standard of conduct for indemnification
under this Agreement.

          Section 16. NOTICES. Any communication, demand or notice to be given
hereunder will be duly given when delivered in writing by hand or first class
mail to the Company at its principal executive office or to an Indemnitee at its
last address appearing in the business

                                      -6-

records of the Company (or to such other addresses as a party may
designate by written notice to the Company).

          Section 17. NO ASSIGNMENTS. No Indemnitee may assign its rights or
obligations under this Agreement without the prior written consent of the
Company

          Section 18. NO THIRD PARTY RIGHTS. Nothing expressed or referred to in
this Agreement will be construed to give any person other than the parties to
this Agreement any legal or equitable right, remedy or claim under or with
respect to this Agreement or any provision of this Agreement. This Agreement and
all of its provisions are for the sole and exclusive benefit of the parties to
this Agreement and their successors and permitted assigns.

          Section 19. COUNTERPARTS. This Agreement may be executed in any number
of counterparts, each of which shall be deemed an original, but all such
counterparts shall together constitute but one and the same instrument.

          IN WITNESS WHEREOF, the parties hereto have entered into this
Agreement as of the date first written above.
