                                    SUMMARY

    THE FOLLOWING SUMMARY HIGHLIGHTS SELECTED INFORMATION FROM THIS PROSPECTUS
AND MAY NOT CONTAIN ALL OF THE INFORMATION THAT IS IMPORTANT TO YOU. THIS
PROSPECTUS INCLUDES SPECIFIC TERMS OF THE NOTES WE ARE OFFERING, AS WELL AS
INFORMATION REGARDING OUR BUSINESS AND DETAILED FINANCIAL DATA. WE ENCOURAGE YOU
TO READ THIS PROSPECTUS IN ITS ENTIRETY.

                               THE EXCHANGE OFFER

    On August 24, 1999, we issued $100,000,000 aggregate principal amount of
9 1/2% Senior Notes due 2004 to Salomon Smith Barney Inc. and Donaldson, Lufkin
& Jenrette Securities Corporation in a private offering. These initial
purchasers placed the notes with institutional investors in transactions exempt
from the registration requirements of the Securities Act of 1933 pursuant to
Section 4(2) of, and Regulation S under, the Securities Act and applicable state
securities laws.

EXCHANGE AND REGISTRATION RIGHTS AGREEMENT

    When we issued the initial notes, we entered into a Registration Rights
Agreement in which we agreed to use our reasonable best efforts to complete an
exchange offer for the initial notes on or prior to December 22, 1999.

THE EXCHANGE OFFER

    Under the terms of the exchange offer, you are entitled to exchange the
initial notes for registered exchange notes with substantially identical terms.
You should read the discussion under the heading "Description of the Exchange
Notes" for further information regarding the exchange notes. As of this date,
there are $100.0 million aggregate principal amount of the initial notes
outstanding. The initial notes may be tendered only in integral multiples of
$1,000.

RESALE OF EXCHANGE NOTES

    We believe that the exchange notes issued in the exchange offer may be
offered for resale, resold or otherwise transferred by you without compliance
with the registration and prospectus delivery provisions of the Securities Act,
provided that:

    - you are acquiring the exchange notes in the ordinary course of your
      business;

    - you are not participating, do not intend to participate, and have no
      arrangement or understanding with any person to participate, in the
      distribution of the exchange notes; and

    - you are not an "affiliate" of ours.

    If any of the foregoing are not true and you transfer any exchange note
without delivering a prospectus meeting the requirements of the Securities Act
or without an exemption from the registration requirements of the Securities
Act, you may incur liability under the Securities Act. We do not assume or
indemnify you against that liability.

    If you are a broker-dealer and receive exchange notes for your own account
in exchange for initial notes that you acquired as a result of market making or
other trading activities, you must acknowledge that you will deliver a
prospectus meeting the requirements of the Securities Act upon any resale of the
exchange notes. A broker-dealer may use this prospectus in connection with an
offer to resell, resale or other transfer of the exchange notes. We will take
steps to ensure that the issuance of the exchange notes will comply with state
securities or "blue sky" laws.

                                       1
<PAGE>
CONSEQUENCES OF FAILURE TO EXCHANGE INITIAL NOTES

    If you do not exchange your initial notes for exchange notes, subject to
some exceptions, you will no longer be able to require us to register the
initial notes under the Securities Act. In addition, you will not be able to
offer or sell the initial notes unless:

    - they are registered under the Securities Act (and we will have no
      obligation to register them, except for some limited exceptions), or

    - you offer or sell them under an exemption from the requirements of, or in
      a transaction not subject to, the Securities Act.

EXPIRATION DATE

    The exchange offer will expire at 5:00 p.m., New York City time, on
            , 1999 unless we decide to extend the expiration date.

INTEREST ON THE EXCHANGE NOTES

    The exchange notes will accrue interest at 9 1/2% per year, beginning on the
last date we paid interest on the initial notes exchanged. We will pay interest
on the exchange notes on February 15 and August 15 of each year.

CONDITIONS TO THE EXCHANGE OFFER

    We will proceed with the exchange offer, so long as:

    - the exchange offer does not violate any applicable law or applicable
      interpretation of law of the staff of the Securities and Exchange
      Commission;

    - no litigation materially impairs our ability to proceed with the exchange
      offer; and

    - we obtain all governmental approvals we deem necessary for the exchange
      offer.

PROCEDURES FOR TENDERING INITIAL NOTES

    If you wish to accept the exchange offer, you must:

    - complete, sign and date the letter of transmittal, or a facsimile of it,
      and

    - send the letter of transmittal and all other documents required by it,
      including the initial notes to be exchanged, to Firstar Bank, N.A., as
      exchange agent, at the address set forth on the cover page of the letter
      of transmittal. Alternatively, you can tender your initial notes by
      following the procedures for book-entry transfer, as described in this
      document.

GUARANTEED DELIVERY PROCEDURE

    If you wish to tender your initial notes and you cannot get your required
documents to the exchange agent by the expiration date, you may tender your
initial notes according to the guaranteed delivery procedure described under the
heading "The Exchange Offer--Guaranteed Delivery Procedure."

WITHDRAWAL RIGHTS

    You may withdraw the tender of your initial notes at any time prior to 5:00
p.m., New York City time, on the expiration date of the exchange offer. To
withdraw, you must send a written or facsimile transmission notice of withdrawal
to the exchange agent at its address set forth herein under "The Exchange
Offer--Exchange Agent" by 5:00 p.m., New York City time, on the expiration date.

                                       2

ACCEPTANCE OF INITIAL NOTES AND DELIVERY OF EXCHANGE NOTES

    If all the conditions to the exchange offer are satisfied or waived, we will
accept any and all initial notes that are properly tendered in the exchange
offer prior to 5:00 p.m., New York City time, on the expiration date. We will
deliver the exchange notes promptly after the expiration date.

TAX CONSIDERATIONS

    We believe that the exchange of initial notes for exchange notes will not be
a taxable exchange for federal income tax purposes. You should consult your tax
adviser about the tax consequences of the exchange as they apply to your
individual circumstances.

EXCHANGE AGENT

    Firstar Bank, N.A. is serving as exchange agent for the exchange offer.

FEES AND EXPENSES

    We will bear all expenses related to consummating the exchange offer and
complying with the Registration Rights Agreement.

OUR COMMON STOCK OFFERING

    Simultaneously with the initial note offering, we converted our firm from
partnership to corporate form and completed an initial public offering of
10,500,000 shares of our common stock at an initial public offering price of $14
per share. We received net proceeds of approximately $134.7 million in our
common stock offering.

USE OF PROCEEDS

    We will not receive any cash proceeds from the issuance of the exchange
notes. We used the proceeds from the sale of the initial notes to redeem some
limited partnership and membership interests and to repay certain subordinated
indebtedness as part of the reorganization of our firm from partnership to
corporate form.

                              LABRANCHE & CO INC.

    Founded in 1924, our subsidiary, LaBranche & Co., is 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

                                       3
<PAGE>
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 43 new common stock listings to our firm. In addition, we have
acquired three specialist operations since 1997, adding 131 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.

    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;

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

    - increase our capital base and our access to capital.

    On a pro forma basis, we generated $137.9 million of revenue and $81.3
million of EBITDA in 1998 and $103.5 million of revenue and $61.8 million of
EBITDA for the first six months of 1999.

PRINCIPAL EXECUTIVE OFFICE

    Our headquarters are located at One Exchange Plaza, New York, New York 10006
(telephone number (212) 820-0400).

                    REORGANIZATION AND RELATED TRANSACTIONS

    LaBranche & Co Inc. is a recently formed holding corporation, and our assets
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, was effected through the transactions summarized below. All these
transactions were completed simultaneously with the completion of our initial
note offering and our common stock offering.

                                     [LOGO]

    - The members of LaB Investing Co. L.L.C. exchanged their membership
      interests in LaB Investing Co. L.L.C. for an aggregate of 34,816,334
      shares of our common stock. In addition to receiving a portion of those
      shares, three members of LaB Investing Co. L.L.C. also received an
      aggregate of $9.0 million in cash as part of the exchange. We thus became
      the sole member of LaB Investing Co. L.L.C., and LaB Investing Co. L.L.C.
      continues to be the general partner of LaBranche & Co.

    - The limited partners of LaBranche & Co., other than Mill Bridge, Inc.,
      exchanged their limited partnership interests in LaBranche & Co. for an
      aggregate of $66.2 million in cash, 558,666 shares of our common stock and
      subordinated indebtedness of $350,000.

    - Mill Bridge, Inc., a subsidiary of Van der Moolen Holding NV, received
      $90.0 million from us in exchange for its limited partnership interest in
      LaBranche & Co., including $74.0 million in cash and a note for $16.0
      million. In addition, we repaid $5.0 million of subordinated debt to an
      affiliate of Van der Moolen.

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

    - We granted (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 our common stock to employees who are not managing
      directors, in each case under our Equity Incentive Plan.

<S>                             <C>
Securities Offered............  $100,000,000 principal amount of 9 1/2% Senior Notes due
                                2004.

Maturity......................  August 15, 2004.

Interest Payment Dates........  February 15 and August 15, commencing on February 15, 2000.

Sinking Fund..................  None.

Ranking.......................  The exchange notes are senior obligations of LaBranche & Co
                                Inc. and will rank equally with our existing and future
                                other unsecured senior indebtedness. They will rank senior
                                in right of payment to all of our current and future
                                subordinated indebtedness for borrowed money, except secured
                                indebtedness that expressly provides that it is senior to
                                the exchange notes.

                                We may issue additional senior indebtedness subject to
                                certain limitations. At June 30, 1999, on a pro forma basis,
                                our total consolidated indebtedness would have been $162.5
                                million. For more details, see "Description of Exchange
                                Notes."

Optional Redemption...........  The exchange notes will be redeemable, at any time, in whole
                                or in part, at a price equal to 100% of the principal amount
                                plus accrued and unpaid interest, if any, to the date of
                                redemption plus a make-whole premium, as described under
                                "Description of Exchange Notes--Optional Redemption."

Change of Control.............  If we sell substantially all of our assets or experience
                                specific kinds of changes of control, we must offer to
                                repurchase the exchange notes at a price in cash equal to
                                101% of their principal amount, plus accrued and unpaid
                                interest, if any, to the date of purchase.

Covenants.....................  The exchange notes will be issued under an indenture with
                                Firstar Bank, N.A. The indenture contains certain covenants
                                that, among other things, limits our ability to:

                                    - borrow money;
                                    - pay dividends on our stock or purchase our stock;
                                    - make investments in certain subsidiaries;
                                    - engage in transactions with stockholders and
                                      affiliates;
                                    - create liens on our assets; and
                                    - sell assets or engage in mergers and consolidations.

                                For more details, see "Description of Exchange
                                Notes--Certain Covenants."

Use of Proceeds...............  We will not receive any cash proceeds from the issuance of
                                the exchange notes. We used the proceeds from the sale of
                                the initial notes to redeem some limited partnership and
                                membership interests and to repay certain subordinated
                                indebtedness as part of the reorganization of our firm from
                                partnership to corporate form.

</TABLE>

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

(A) For puposes of this ratio, earnings represent pre-tax income plus limited
    partners' interest in earnings of subsidiary and fixed charges. Fixed
    charges represent interest expensed and capitalized, as well as amortized
    premiums, discounts and capitalized expenses related to indebtedness.

    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. As of August 24, 1999, we reorganized our firm
from partnership to corporate form and redeemed limited partnership and
membership interests. As a corporation, we 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 August 24, 1999. See "--Reorganization and Related
Transactions" and "--Summary Pro Forma Consolidated Financial Data." As a
partnership, we generally had 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 are 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 give
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 consolidated balance
sheet data as of June 30, 1999 give further effect to (1) the reorganization and
related transactions as if they occurred on June 30, 1999, (2) our initial note
offering, (3) the application of the net proceeds of our initial note offering,
(4) the sale by us of 10,500,000 shares of common stock in our common stock
offering, after deducting the underwriting discounts and offering expenses
payable by us, and (5) the application of the net proceeds from our common stock
offering. The pro forma consolidated financial information has been prepared by
our management and is not necessarily indicative of the results that would have
been achieved had the above-described transactions occurred on the dates
indicated or that may be achieved in the future.

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

(A) Employee compensation and benefits was adjusted to reflect managing
    directors' compensation based on authorized revised compensation policies
    which were implemented at the time of the reorganization.

(B) Reflects pro forma repayment of $5.0 million of subordinated liabilities
    owed to a limited partner and reverses the related interest expense.
    Reflects our initial note offering, the issuance of a $16.0 million note and
    $350,000 of subordinated indebtedness and the related interest expense.

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

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

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

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

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

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

(I) Reflects the redemption of limited partnership interests for $164.4 million,
    comprised of $140.2 million in cash, a $16.0 million note, $350,000 of
    subordinated indebtedness and $7.8 million in common stock. Reflects
    redemption of membership interests for $9.0 million in cash.

(J) Reflects net proceeds of $134.7 million received upon completion of our
    common stock offering.

(K) Excludes subordinated liabilities related to contributed exchange
    memberships.

(L) Calculated on an annualized basis.

(M) Net debt means total debt less cash and short-term investments.

(N) For purposes of this ratio, earnings represent pre-tax income plus fixed
    charges. Fixed charges represent interest expensed and capitalized, as well
    as amortized premiums, discounts and capitalized expenses related to
    indebtedness.

                                  RISK FACTORS

    YOU SHOULD CONSIDER CAREFULLY THE FOLLOWING RISKS BEFORE YOU DECIDE TO MAKE
AN INVESTMENT IN THE EXCHANGE NOTES. 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.

    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.

IF YOU DO NOT PARTICIPATE IN THE EXCHANGE OFFER, YOU WILL CONTINUE TO BE SUBJECT
  TO TRANSFER RESTRICTIONS.

    If you do not exchange your initial notes for exchange notes pursuant to the
exchange offer, you will continue to be subject to the restrictions on transfer
of your initial notes. We do not intend to register the initial notes under the
Securities Act. To the extent initial notes are tendered and accepted in the
exchange offer, the trading market, if any, for the initial notes would be
adversely affected. See "The Exchange Offer."

A LIQUID TRADING MARKET FOR THE EXCHANGE NOTES MAY NOT DEVELOP.

    There has not been an established trading market for the exchange notes.
Although each initial purchaser has informed us that it currently intends to
make a market in the exchange notes, it has no obligation to do so and may
discontinue any such market making at any time without notice. The initial notes
were offered and sold only to qualified institutional buyers and to persons
outside the United States and were are subject to restrictions on transfer.

    The initial notes were designated as eligible for trading in the PORTAL
Market. However, we did not apply for listing of the initial notes and do not
intend to apply for listing of the exchange notes, on any securities exchange or
for quotation through the National Association of Securities Dealers Automated
Quotation System.

    The liquidity of any market for the exchange notes will depend upon the
number of holders of the exchange notes, our performance, the market for similar
securities, the interest of securities dealers in making a market in the
exchange notes and other factors. A liquid trading market may not develop for
the exchange notes.

WE WILL HAVE SIGNIFICANT INDEBTEDNESS AND INTEREST PAYMENT OBLIGATIONS.

    We are highly leveraged. On a pro forma basis, after giving effect to our
initial note offering, our common stock offering, our incurrence of $16.4
million of other indebtedness, the reorganization of our firm from partnership
to corporate form and our use of the proceeds, at June 30, 1999, we would have
had $162.5 million of consolidated outstanding debt. Our total consolidated
debt, as a percentage of capitalization, would have been 41.5%. These
calculations of debt exclude subordinated liabilities related to contributed
exchange memberships. We may also need to incur additional debt in the future
for working capital or to complete acquisitions, even though our principal
credit facility imposes some limits on our ability to do so. Our high level of
indebtedness could have important consequences to you, which include the
following:

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

                                       10
<PAGE>
    - our ability to use operating cash flow in other areas of our business will
      be limited because we must dedicate a substantial portion of these funds
      to make principal and interest payments;

    - we may not be able to compete with others who are not as highly leveraged;
      and

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

    Our ability to pay interest on the exchange notes and to satisfy our other
debt obligations will depend upon our future operating performance and our
ability to obtain additional debt or equity financing. Prevailing economic
conditions and financial, business and other factors, many of which are beyond
our control, will affect our ability to make these payments. If in the future we
cannot generate sufficient cash from operations to make scheduled payments on
the notes or to meet our other obligations, we will need to refinance the
exchange notes, obtain additional financing or sell assets. We cannot assure you
that our business will generate cash flow, or that we will be able to obtain
funding, sufficient to satisfy our debt service requirements.

    The exchange notes will be effectively subordinated to our existing and
future secured indebtedness to the extent of the assets securing such
indebtedness. In addition, because we, LaBranche & Co Inc., are a recently
formed holding company with no operations of our own, we are dependent on
distributions from LaBranche & Co. and LaB Investing Co. L.L.C. to pay interest
and principal on our debt. The exchange notes will be effectively subordinated
to all of the indebtedness of LaBranche & Co. and LaB Investing Co. L.L.C.,
including subordinated debt. This structural subordination may adversely affect
our ability to service our debt and could result in insolvency or other
circumstances that could adversely affect our ability to satisfy our payment
obligations with respect to the exchange notes. On a pro forma basis, after
giving effect to our initial note offering and our use of the proceeds, at June
30, 1999, LaBranche & Co. would have had $46.5 million of outstanding debt.
LaBranche & Co. also has the ability to borrow $100.0 million under an agreement
relating to a revolving credit facility with The Bank of New York which was
originally entered into in June of 1998 and increased and extended in June 1999
(the "Credit Agreement").

    Further, 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 the exchange notes. See "--We are subject to net capital requirements"
and "Business--Operations--Regulatory Matters" for a discussion of our net
capital requirements.

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

    The covenants in our existing debt agreements, including the Credit
Agreement, the note purchase agreements relating to LaBranche & Co.'s existing
senior subordinated indebtedness and the indenture governing the notes, and any
future financing agreements, may adversely affect our ability to finance future
operations or capital needs or to engage in other business activities. These
covenants limit or restrict our ability and the ability of our subsidiaries to:

    - incur additional debt;

    - pay dividends and make distributions;

    - repurchase our securities;

    - make certain investments;

    - create liens on our assets;

                                       11
<PAGE>
    - transfer or sell assets;

    - enter into transactions with affiliates;

    - issue or sell stock of subsidiaries; or

    - merge or consolidate.

    In addition, the Credit Agreement and the note purchase agreements relating
to LaBranche & Co.'s existing senior subordinated indebtedness also require
LaBranche & Co. to comply with certain financial ratios. LaBranche & Co.'s
ability to comply with these ratios may be affected by events beyond our or its
control. If any of the covenants in our Credit Agreement, the note purchase
agreements or the indenture are breached, or if LaBranche & Co. is unable to
comply with required financial ratios, it may be in default under the Credit
Agreement or the note purchase agreements and we may be in default under the
indenture. A significant portion of our indebtedness then may become immediately
due and payable. We are not certain whether we would have, or be able to obtain,
sufficient funds to make these accelerated payments, including payments on the
exchange notes. Compliance with the covenants is also a condition to borrowings
under the Credit Agreement on which LaBranche & Co. relies to fund its
liquidity. See "Description of Notes" and "Description of Other Indebtedness."

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

    Upon the occurrence of a change of control, we will be required to offer to
repurchase all outstanding exchange notes at a price equal to 101% of their
principal amount, together with accrued and unpaid interest, if any, to the date
of repurchase. Certain important corporate events, such as leveraged
recapitalizations that would increase our level of indebtedness, would not
constitute a change of control. If a change of control were to occur, it is
possible that we would not have sufficient funds to repurchase the exchange
notes owned by holders seeking to accept our offer or that restrictions in the
Credit Agreement or the note purchase agreements relating to LaBranche & Co.'s
existing senior subordinated indebtedness will not allow such repurchases.
Furthermore, a change of control will most likely trigger a default under the
Credit Agreement and the note purchase agreements. To the extent we do not have
sufficient funds to meet our repurchase obligations and any other obligations in
respect of the Credit Agreement and the note purchase agreements, we would
necessarily seek third-party financing. However, it is possible that we will not
be able to obtain such financing.

THE EXCHANGE NOTES MAY BE SUBJECT TO FRAUDULENT TRANSFER STATUTES.

    Under federal or state fraudulent transfer laws, a court could avoid all or
a portion of our obligations to the holders of the exchange notes, subordinate
our obligations to the holders of the exchange notes to our other existing and
future indebtedness, the effect of which would be to entitle the other creditors
to be paid in full before any payment could be made on the exchange notes, and
take other action detrimental to the holders of the exchange notes, including,
in certain circumstances, invalidating the exchange notes if it were to find
that,

    - we issued the initial notes with the intent of hindering, delaying or
      defrauding current or future creditors or at the time the initial notes
      were issued, we

     - (A) received less than fair consideration or reasonably equivalent value
       for incurring the indebtedness represented by the initial notes and

     - (B)(1) were insolvent or were rendered insolvent by reason of the
       issuance of the initial notes, (2) were engaged, or about to engage, in a
       business or transaction for which our assets were unreasonably small or
       (3) intended to incur, or believed (or should have believed) we would

                                       12
<PAGE>
       incur, debts beyond our ability to pay as the debts mature (as all of the
       foregoing terms are defined in or interpreted under the fraudulent
       transfer statutes).

    We cannot assure you that, in that event, any repayment on the exchange
notes would ever be recovered by the holders of the exchange notes.

    The definition of insolvency for purposes of the foregoing considerations
varies among jurisdictions depending upon the federal or state law that is being
applied. However, we generally would be considered insolvent at the time we
incur the indebtedness constituting the initial notes if the fair market value
(or fair saleable value) of our assets is less than the amount required to pay
our total existing debts and liabilities (including the probable liability on
contingent liabilities) as they become absolute or matured or we are incurring
debts beyond our ability to pay as the debts mature. We cannot assure you as to
what standard a court would apply in order to determine whether we were
"insolvent" as of the date the initial notes were issued, or that, regardless of
the method of valuation, a court would not determine that we were insolvent on
that date. Nor can we assure you that a court would not determine, regardless of
whether we were insolvent on the date the initial notes were issued, that the
payments constituted fraudulent transfers on another ground. To the extent that
proceeds from the sale of the initial notes were used to repurchase limited
partnership interests of LaBranche & Co., to repay indebtedness of LaBranche &
Co. or to make a distribution to a limited partner of LaBranche & Co. or a
member of LaB Investing Co. L.L.C. in respect of a limited partnership interest
or a membership interest, a court may find that we did not receive fair
consideration or reasonably equivalent value for the incurrence of the
indebtedness represented by the initial notes.

    Based upon financial and other information currently available to us, our
management believes that the initial notes were incurred for proper purposes and
in good faith and that we were solvent and continue to be solvent after issuing
the initial notes, will continue to have sufficient capital for carrying on our
business and will be able to pay our debts as they mature. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

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

    Our business depends on the availability of adequate capital. We cannot be
sure that we will have sufficient capital in the future or that additional
financing will be available on a timely basis, or on terms favorable to us.
Historically, we have satisfied these needs with internally generated funds, our
bank credit facilities and the issuance of subordinated debt. We currently
anticipate that the net proceeds from our initial note offering and our common
stock offering, 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."

                                       13
<PAGE>
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 REVENUE.

    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."

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.

                                       14

OUR QUARTERLY RESULTS MAY FLUCTUATE SIGNIFICANTLY.

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

    - a decrease in trading volume on the NYSE;

    - 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.

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.

    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

                                       15
<PAGE>
information regarding the rules which govern our activities as a specialist, see
"Business--Operations-- NYSE Rules Governing Our Specialist Activities."

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

    - hardware or software failure; or

    - power or telecommunications failure.

    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.

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

                                       16
<PAGE>
other technological developments and advances, it could have an adverse effect
on the success of the NYSE, including its ability to grow, to manage its trading
volumes 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, Chief
Executive Officer and President. The loss of the services of any of our key
personnel or the inability to identify, hire, train and retain other qualified
personnel in the future could have an adverse effect on our business, financial
condition and/or operating results. We have 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 our initial note offering, our common stock offering and
the reorganization of our firm from partnership to corporate form, our managing
directors received substantial amounts of our common stock in exchange for their
interests in LaB Investing Co. L.L.C. Because the shares of common stock were
received in exchange for membership interests, ownership of the shares is not be
dependent upon the continued employment of those managing directors. In
addition, employees who are not managing directors received grants of stock
options and restricted stock units. The steps we have taken to encourage the
continued service of these individuals, who include key senior personnel in our
specialist activities, after our initial note offering and our common stock
offering may not be effective. For a description of the compensation plan for
our employees implemented after our initial note offering and our common stock
offering, see "Management--Executive Compensation" and "Incentive Awards to Our
Employees."

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 approximately 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

                                       17
<PAGE>
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 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
  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

                                       18
<PAGE>
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, the 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 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.

                                       19
<PAGE>
WE CANNOT PREDICT THE EFFECT A PROPOSED PUBLIC OFFERING BY THE NYSE WOULD HAVE
  ON OUR BUSINESS.

    The NYSE 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.

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

                                       20
<PAGE>
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.

    Our managing directors own approximately 75.6% 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, Chief Executive Officer and
President, James G. Gallagher and Alfred O. Hayward, Jr., each an executive
officer and director. Accordingly, these individuals have the ability to control
all matters requiring approval by our stockholders. These matters include the
election and removal of directors and the approval of any merger, consolidation
or sale of all or substantially all of our assets. In addition, they are able to
dictate the management of our business and affairs. This concentration of
ownership could have the effect of delaying, deferring or preventing a change in
control, a merger or consolidation, a takeover or another business combination.
The interests of these individuals may differ from the interests of holders of
the notes.

                               THE EXCHANGE OFFER

TERMS OF THE EXCHANGE OFFER

    GENERAL

    In connection with the issuance of the initial notes pursuant to a purchase
agreement dated as of August 18, 1999 by and among us and the initial purchasers
(the "Purchase Agreement"), the initial purchasers and their respective
assignees became entitled to the benefits of the Registration Rights Agreement
dated as of August 24, 1999 by and among us and the initial purchasers (the
"Registration Rights Agreement").

    The Registration Rights Agreement requires us to file the registration
statement of which this prospectus is a part for a registered exchange offer
relating to an issue of new notes identical in all material respects to the
initial notes but containing no restrictive legend. Under the Registration
Rights Agreement, we are required to:

    - file the registration statement not later than 45 days following the date
      of original issuance of the initial notes (the "Issue Date");

    - use our reasonable best efforts to cause the registration statement to be
      declared effective by the SEC not later than 90 days after the Issue Date;

    - keep the exchange offer open for not less than 20 business days (or longer
      if required by applicable law) after the date that notice of the exchange
      offer is mailed to holders of the initial notes;

    - use our reasonable best efforts to consummate the exchange offer not later
      than 120 days after the Issue Date;

    - mail, or cause to be mailed, to each holder of record entitled to
      participate in the exchange offer a copy of the prospectus forming part of
      the exchange registration statement, together with an appropriate letter
      of transmittal and related documents;

    - utilize the services of a depositary for the exchange offer with an
      address in the Borough of Manhattan, The City of New York;

    - permit holders to withdraw validly tendered notes at any time prior to the
      close of business, New York time, on the last business day on which the
      exchange offer shall remain open; and

    - otherwise comply in all material respects with all applicable laws, rules
      and regulations.

    The exchange offer being made hereby, if commenced and consummated within
the time periods described in this paragraph, will satisfy those requirements
under the Registration Rights Agreement.

    Upon the terms and subject to the conditions set forth in this prospectus
and in the letter of transmittal, all initial notes validly tendered and not
withdrawn prior to 5:00 p.m., New York City time, on the expiration date will be
accepted for exchange. Exchange notes of the same class will be issued in
exchange for an equal principal amount of outstanding initial notes accepted in
the exchange offer. Initial notes may be tendered only in integral multiples of
$1,000. This prospectus, together with the letter of transmittal, is being sent
to all record holders of initial notes as of             , 1999. The exchange
offer is not conditioned upon any minimum principal amount of initial notes
being tendered in exchange. However, our obligation to accept initial notes for
exchange is subject to certain conditions as set forth herein under
"--Conditions."

    Initial notes will be deemed accepted when, as and if the Trustee has given
oral or written notice to the exchange agent. The exchange agent will act as
agent for the tendering holders of initial notes for the purposes of receiving
the exchange notes and delivering them to the holders.

                                       22
<PAGE>
    Based on interpretations by the staff of the SEC, as set forth in no-action
letters issued to other issuers, we believe that the exchange notes issued in
the exchange offer may be offered for resale, resold or otherwise transferred by
each holder without compliance with the registration and prospectus delivery
provisions of the Securities Act, provided that:

    - the holder is not a broker-dealer who acquires the exchange notes directly
      from us for resale pursuant to Rule 144A under the Securities Act or any
      other available exemption under the Securities Act;

    - the holder is not our "affiliate", as that term is defined in Rule 405
      under the Securities Act; and

    - the exchange notes are acquired in the ordinary course of the holder's
      business and the holder is not engaged in, and does not intend to engage
      in, a distribution of the exchange notes and has no arrangement or
      understanding with any person to participate in a distribution of the
      exchange notes.

    By tendering the initial notes in exchange for exchange notes, each holder,
other than a broker-dealer, will represent to us that:

    - any exchange notes to be received by it will be acquired in the ordinary
      course of its business;

    - it is not engaged in, and does not intend to engage in, a distribution of
      the exchange notes and has no arrangement or understanding to participate
      in a distribution (within the meaning of the Securities Act) of the
      exchange notes; and

    - it is not our affiliate, as defined in Rule 405 under the Securities Act,
      or if it is our affiliate, it will comply with the registration and
      prospectus delivery requirements of the Securities Act, to the extent
      applicable.

    If, prior to consummation of the exchange offer, an initial purchaser holds
any notes acquired by it and having, or that are reasonably likely to be
determined to have, the status of an unsold allotment in the initial
distribution, or any other holder of notes is not entitled to participate in the
exchange offer, we, upon the request of that initial purchaser or any holder
shall, simultaneously with the delivery of the exchange notes in the exchange
offer, issue and deliver to that initial purchaser and any such holder, in
exchange (the "private exchange") for such notes held by that initial purchaser
and any such holder, a like principal amount of our debt securities that are
identical in all material respects to the exchange notes (the "private exchange
notes") (and that are issued pursuant to the same indenture as the exchange
notes). The private exchange notes will bear the same CUSIP number as the
exchange notes.

    If a holder of initial notes is engaged in or intends to engage in a
distribution of the exchange notes or has any arrangement or understanding with
respect to the distribution of the exchange notes to be acquired pursuant to the
exchange offer, the holder may not rely on the applicable interpretations of the
staff of the SEC and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any secondary resale
transaction. Each broker-dealer that receives exchange notes for its own account
in the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of such exchange notes. The letter of transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.

    This prospectus, as it may be amended or supplemented from time to time, may
be used by a broker-dealer to satisfy their prospectus delivery obligations
under the Securities Act in connection with resales of exchange notes for their
own accounts. We have agreed that we will keep the registration statement of
which this prospectus is a part effective for a period of up to six months or
such earlier

                                       23
<PAGE>
date as each participating broker-dealer shall have notified us in writing that
it has resold all exchange notes acquired in the exchange offer. See "Plan of
Distribution."

    As soon as practicable after the close of the exchange offer, we will:

    - accept for exchange all registrable notes validly tendered and not validly
      withdrawn as part of the exchange offer; and

    - deliver to the Trustee for cancellation all registrable notes so accepted
      for exchange and cause the Trustee to authenticate and deliver promptly to
      each holder of registrable notes, exchange notes or private exchange
      notes, as the case may be, equal in principal amount to the securities of
      such holder so accepted for exchange.

    In the event that:

    a)  we are not permitted to effect the exchange offer because the exchange
       offer is not permitted by applicable law or SEC policy;

    b)  the exchange offer is not completed within 120 days of the Issue Date;

    c)  any holder of any private exchange notes so requests in writing to us
       within 30 days after the consummation of the exchange offer; or

    d)  in the case of any holder that participates in the exchange offer, the
       holder does not receive exchange notes on the date of the exchange that
       may be sold without restriction under state and federal securities laws
       (other than due solely to the status of such holder as our affiliate
       within the meaning of the Securities Act):

then we shall:

    1)  promptly deliver to the holders and the trustee written notice of the
       filing of a shelf registration statement under the Registration Rights
       Agreement;

    2)  use our reasonable best efforts to file with the SEC an initial shelf
       registration statement for an offering to be made on a continuous basis
       under Rule 415 covering all of the registrable notes not exchanged in the
       exchange offer and exchange notes as to which paragraph (d) above is
       applicable, on or before the 45(th) day after the occurrence of any one
       of the events specified in the Registration Rights Agreement and
       summarized above which gives rise to our obligation to file a shelf
       registration statement; and

    3)  use our reasonable best efforts to cause the shelf registration
       statement to be declared effective under the Securities Act on or before
       the 45(th) day after the initial shelf registration filing date.

    We will, in the event that a shelf registration statement is filed, provide
to each holder of the initial notes copies of the prospectus that is a part of
the shelf registration statement, notify each holder when the shelf registration
statement has become effective and take certain other actions as are required to
permit unrestricted resales of the exchange notes. A holder that sells initial
notes pursuant to the shelf registration statement will be required to be named
as a selling security holder in the related prospectus and to deliver a
prospectus to purchasers, will be subject to certain of the civil liability
provisions under the Securities Act in connection with its sales and will be
bound by the provisions of the Registration Rights Agreement that are applicable
to that holder (including certain indemnification rights and obligations).

    We will pay additional interest if:

    1.  we fail to file the exchange offer registration statement by the 45(th)
       day after the Issue Date;

    2.  the exchange offer registration statement is not declared effective by
       the Securities and Exchange Commission by the 90th day after the Issue
       Date;

    3.  we fail to consummate the exchange offer by 120(th) day after the Issue
       Date;

                                       24
<PAGE>
    4.  the exchange offer registration statement is declared effective but
       thereafter ceases to be effective or usable in connection with resales of
       exchange notes in accordance with and during the periods specified in the
       Registration Rights Agreement;

    5.  we fail to file a shelf registration statement by the 45(th)day
       following the date of the occurrence of one of the events specified in
       the Registration Rights Agreement which gives rise to our obligation to
       file a shelf registration statement;

    6.  the shelf registration statement is not declared effective by the
       Securities and Exchange Commission by the 45(th) day following the
       initial shelf registration filing date; or

    7.  the shelf registration statement is declared effective and thereafter
       ceases to be effective or usable in connection with resales of Transfer
       Restricted Securities (described below) in accordance with and during the
       periods specified in the Registration Rights Agreement.

    Each event described above is a "Registration Default." The term "Transfer
Restricted Securities" means each initial note, or exchange note, until:

    - the date on which the initial note has been exchange by a person other
      than a broker-dealer for a new note in the exchange offer;

    - following the exchange by a broker-dealer in the exchange offer of an
      initial note for an exchange note, the date on which the exchange note is
      sold to a purchaser who receives from the broker-dealer on or prior to the
      date of sale a copy of the exchange offer prospectus;

    - the date on which the initial note has been effectively registered under
      the Securities Act and disposed of under the shelf registration statement;
      or

    - the date on which the initial note is publicly sold under Rule 144 under
      the Securities Act.

    If a Registration Default occurs, we will be obligated to pay, as liquidated
damages, additional interest on the initial notes equal to 0.25% per annum of
the aggregate principal amount of the initial notes held by such holder, during
the 90-day period immediately following the occurrence of the first Registration
Default. The amount of the additional interest will increase by an additional
0.25% per annum at the beginning of each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum aggregate amount of
additional interest equal to 1.00% per annum. Following the cure of all
Registration Defaults, the accrual of additional interest will cease.

    Upon completion of the exchange offer, subject to certain exceptions,
holders of initial notes who do not exchange their initial notes for exchange
notes in the exchange offer will no longer be entitled to registration rights
and will not be able to offer or sell their initial notes, unless the initial
notes are subsequently registered under the Securities Act (which, subject to
certain limited exceptions, we will have no obligation to do), except pursuant
to an exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. See "Risk Factors--If you do not participate
in the exchange offer, you will continue to be subject to transfer
restrictions."

    EXPIRATION DATE; EXTENSIONS; AMENDMENTS; TERMINATION

    The term "expiration date" shall mean       , 1999 (20 business days
following the commencement of the exchange offer), unless the exchange offer is
extended if and as required by applicable law, in which case the term
"expiration date" shall mean the latest date to which the exchange offer is
extended.

    In order to extend the expiration date, we will notify the exchange agent of
any extension by oral or written notice and may notify the holders of the
initial notes by mailing an announcement or by means of a press release or other
public announcement prior to 9:00 A.M., New York City time, on the next business
day after the previously scheduled expiration date.

                                       25
<PAGE>
    We reserve the right to delay acceptance of any initial notes, to extend the
exchange offer or to terminate the exchange offer and not permit acceptance of
initial notes not previously accepted if any of the conditions set forth herein
under "--Conditions" shall have occurred and shall not have been waived by us
(if permitted to be waived), by giving oral or written notice of such delay,
extension or termination to the exchange agent. We also reserve the right to
amend the terms of the exchange offer in any manner deemed by us to be
advantageous to the holders of the initial notes. If any material change is made
to terms of the exchange offer, the exchange offer shall remain open for a
minimum of an additional five business days, if the exchange offer would
otherwise expire during such period. Any such delay in acceptance, extension,
termination or amendment will be followed as promptly as practicable by oral or
written notice of the delay to the exchange agent. If the exchange offer is
amended in a manner determined by us to constitute a material change, we will
promptly disclose the amendment in a manner reasonably calculated to inform the
holders of the initial notes of the amendment including providing public
announcement, or giving oral or written notice to the holders of the initial
notes. A material change in the terms of the exchange offer could include, among
other things, a change in the timing of the exchange offer, a change in the
exchange agent, and other similar changes in the terms of the exchange offer.

    Without limiting the manner in which we may choose to make a public
announcement of any delay, extension, amendment or termination of the exchange
offer, we will have no obligation to publish, advertise, or otherwise
communicate any such public announcement.

    INTEREST ON THE EXCHANGE NOTES

    The exchange notes will accrue interest payable in cash at 9 1/2% per annum,
from the later of:

    - the last interest payment date on which interest was paid on the initial
      notes surrendered in exchange therefor; or

    - if the initial notes are surrendered for exchange on a date subsequent to
      the record date for an interest payment date to occur on or after the date
      of such exchange and as to which interest will be paid, the date of such
      interest payment.

    PROCEDURES FOR TENDERING

    To tender in the exchange offer, a holder of initial notes must complete,
sign and date the letter of transmittal, and mail or otherwise deliver the
letter of transmittal or facsimile, or an agent's message, together with the
initial notes and any other required documents, to the exchange agent prior to
5:00 p.m., New York City time, on the expiration date. In addition:

    - certificates for the initial notes must be received by the exchange agent
      along with the letter of transmittal;

    - a timely confirmation of a book-entry transfer (a "Book-Entry
      Confirmation") of the initial notes, if such procedure is available, into
      the exchange agent's account at The Depository Trust Company (the
      "Book-Entry Transfer Facility" or "DTC") pursuant to the procedure for
      book-entry transfer described below, must be received by the exchange
      agent prior to the expiration date; or

    - the holder must comply with the guaranteed delivery procedures described
      below.

    THE METHOD OF DELIVERY OF INITIAL NOTES, LETTERS OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDERS. INSTEAD OF
DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR
HAND-DELIVERY SERVICE. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT
REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN
ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE TIMELY DELIVERY. NO
LETTERS OF TRANSMITTAL OR INITIAL NOTES SHOULD BE SENT TO US.

                                       26
<PAGE>
    Delivery of all documents must be made to the exchange agent at its address
set forth below. Holders of initial notes may also request their respective
brokers, dealers, commercial banks, trust companies or nominees to tender
initial notes for them.

    The term "agent's message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the exchange agent and forming a part of
a Book-Entry Confirmation, which states that the Book-Entry Transfer Facility
has received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering initial notes that are the subject of the Book-Entry
Confirmation that the participant has received and agrees to be bound by the
terms of the letter of transmittal, and that we may enforce this agreement
against the participant.

    The tender by a holder of initial notes will constitute an agreement between
such holder and us in accordance with the terms and subject to the conditions
set forth herein and in the letter of transmittal.

    Only a holder of initial notes may tender the initial notes in the exchange
offer. The term "holder" for this purpose means any person in whose name initial
notes are registered on our books or any other person who has obtained a
properly completed bond power from the registered holder.

    Any beneficial owner whose initial notes are registered in the name of a
broker, dealer, commercial bank, trust company or other nominee and who wishes
to tender should contact the registered holder promptly and instruct the
registered holder to tender on his or her behalf. If the beneficial owner wishes
to tender on his or her own behalf, such beneficial owner must, prior to
completing and executing the letter of transmittal and delivering his or her
initial notes, either make appropriate arrangements to register ownership of the
initial notes in such owner's name or obtain a properly completed bond power
from the registered holder. The transfer of registered ownership may take
considerable time.

    Signatures on a letter of transmittal or a notice of withdrawal, as the case
may be, must be guaranteed by a member firm of a registered national securities
exchange or of the National Association of Securities Dealers, Inc., a
commercial bank or trust company having an office or correspondent in the United
States or an "eligible guarantor" institution within the meaning of Rule 17Ad-15
under the Exchange Act (each, an "Eligible Institution"), unless the initial
notes tendered pursuant thereto are tendered:

    - by a registered holder (or by a participant in DTC whose name appears on a
      security position listing as the owner) who has not completed the box
      entitled "Special Issuance Instructions" or "Special Delivery
      Instructions" on the letter of transmittal and the exchange notes are
      being issued directly to such registered holder (or deposited into the
      participant's account at DTC); or

    - for the account of an Eligible Institution.

    If the letter of transmittal is signed by the recordholder(s) of the initial
notes tendered thereby, the signature must correspond with the name(s) written
on the face of the initial notes without alteration, enlargement or any change
whatsoever. If the letter of transmittal is signed by a participant in DTC, the
signature must correspond with the name as it appears on the security position
listing as the holder of the initial notes.

    If the letter of transmittal is signed by a person other than the registered
holder of any initial notes listed therein, those initial notes must be endorsed
or accompanied by bond powers and a proxy that authorize such person to tender
the initial notes on behalf of the registered holder, in each case as the name
of the registered holder or holders appear on the initial notes.

    If the letter of transmittal or any initial notes or bond powers are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by us, evidence
satisfactory to us of their authority to so act must be submitted with the
letter of transmittal.

                                       27
<PAGE>
    A tender will be deemed to have been received as of the date when the
tendering holder's duly signed letter of transmittal accompanied by initial
notes, or a timely confirmation received of a book-entry transfer of initial
notes into the exchange agent's account at DTC with an agent's message, or a
notice of guaranteed delivery from an Eligible Institution is received by the
exchange agent. Issuances of exchange notes in exchange for initial notes
tendered pursuant to a notice of guaranteed delivery by an Eligible Institution
will be made only against delivery of the letter of transmittal and any other
required documents, and the tendered initial notes or a timely confirmation
received of a book-entry transfer of initial notes into the exchange agent's
account at DTC with the exchange agent.

    All questions as to the validity, form, eligibility, time of receipt,
acceptance and withdrawal of the tendered initial notes will be determined by us
in our sole discretion, which determination will be final and binding. We
reserve the absolute right to reject any and all initial notes not properly
tendered or any initial notes which, if accepted, would, in our opinion or that
of our counsel, be unlawful. We also reserve the absolute right to waive any
conditions of the exchange offer or irregularities or defects in tender as to
particular initial notes. Our interpretation of the terms and conditions of the
exchange offer (including the instructions in the letter of transmittal) will be
final and binding on all parties. Unless waived, any defects or irregularities
in connection with tenders of initial notes must be cured within such time as we
will determine. None of us, the exchange agent and any other person shall be
under any duty to give notification of defects or irregularities with respect to
tenders of initial notes, and none of them shall incur any liability for failure
to give such notification. Tenders of initial notes will not be deemed to have
been made until such irregularities have been cured or waived. Any initial notes
received by the exchange agent that are not properly tendered and as to which
the defects or irregularities have not been cured or waived will be returned
without cost by the exchange agent to the tendering holders of such initial
notes, unless otherwise provided in the letter of transmittal, as soon as
practicable following the expiration date.

    In addition, we reserve the right in our sole discretion, subject to the
provision of the Indenture, to:

    - purchase or make offers for any initial notes that remain outstanding
      subsequent to the expiration date or, as set forth under "--Expiration
      Date; Extensions; Amendments; Termination," to terminate the exchange
      offer in accordance with the terms of the Registration Rights Agreement;
      and

    - to the extent permitted by applicable law, purchase initial notes in the
      open market, in privately negotiated transactions or otherwise.

    The terms of any such purchases or offers could differ from the terms of the
exchange offer.

    ACCEPTANCE OF INITIAL NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES

    Upon satisfaction or waiver of all of the conditions to the exchange offer,
all initial notes properly tendered will be accepted, promptly after the
expiration date, and the exchange notes will be issued promptly after acceptance
of the initial notes. See "--Conditions" below. For purposes of the exchange
offer, initial notes shall be deemed to have been accepted as validly tendered
for exchange when, as and if we have given oral or written notice thereof to the
exchange agent.

    In all cases, issuance of exchange notes for initial notes that are accepted
for exchange pursuant to the exchange offer will be made only after timely
receipt by the exchange agent of certificates for such initial notes or a timely
Book-Entry Confirmation of such initial notes into the exchange agent's account
at the Book-Entry Transfer Facility, a properly completed and duly executed
letter of transmittal and all other required documents. If any tendered initial
notes are not accepted for any reason set forth in the terms and conditions of
the exchange offer or if initial notes are submitted for a greater principal
amount than the holder desires to exchange, such unaccepted or non-exchanged
initial

                                       28
<PAGE>
notes will be returned without expense to the tendering holder as promptly as
practicable after the expiration or termination of the exchange offer. In the
case of initial notes tendered by the book-entry transfer procedures described
below, the non-exchanged initial notes will be credited to an account maintained
with the Book-Entry Transfer Facility.

    BOOK-ENTRY TRANSFER

    The exchange agent will make a request to establish an account with respect
to the initial notes at the Book-Entry Transfer Facility for purposes of the
exchange offer within two business days after the date of this prospectus. Any
financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of initial notes by causing the
Book-Entry Transfer Facility to transfer such initial notes into the exchange
agent's account at the Book-Entry Transfer Facility in accordance with such
Book-Entry Transfer Facility's procedures for transfer. However, although
delivery of initial notes may be effected through book-entry transfer into the
exchange agent's account at the Book-Entry Transfer Facility, an agent's message
or the letter of transmittal or facsimile thereof with any required signature
guarantees and any other required documents must, in any case, be transmitted to
and received by the exchange agent at one of the addresses set forth below under
"--Exchange Agent" on or prior to the expiration date or the guaranteed delivery
procedures described below must be complied with. DELIVERY OF DOCUMENTS TO DTC
DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT. All references in the
prospectus to deposit of initial notes shall be deemed to include the Book-Entry
Transfer Facility's book-entry delivery method.

    GUARANTEED DELIVERY PROCEDURE

    If a registered holder of the initial notes desires to tender the notes, and
the notes are not immediately available, or time will not permit the holder's
initial notes or other required documents to reach the exchange agent before the
expiration date, or the procedures for book-entry transfer cannot be completed
on a timely basis and an agent's message delivered, a tender may be effected if:

    1.  the tender is made through an Eligible Institution;

    2.  prior to the expiration date, the exchange agent receives from such
       Eligible Institution a properly completed and duly executed letter of
       transmittal or facsimile thereof and notice of guaranteed delivery,
       substantially in the form provided by us, by facsimile transmission, mail
       or hand delivery, setting forth the name and address of the holder of the
       initial notes and the amount of initial notes tendered, stating that the
       tender is being made thereby and guaranteeing that within five business
       days after the expiration date, the certificates for all physically
       tendered initial notes, in proper form for transfer, or a Book-Entry
       Confirmation, as the case may be, and any other documents required by the
       letter of transmittal will be deposited by the Eligible Institution with
       the exchange agent; and

    3.  the certificates for all physically tendered initial notes, in proper
       form for transfer, or a Book-Entry Confirmation, as the case may be, and
       all other documents required by the letter of transmittal are received by
       the exchange agent within five business days after the expiration date.

    WITHDRAWAL OF TENDERS

    Except as otherwise provided herein, tenders of initial notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the expiration
date.

    For a withdrawal to be effective, a written notice of withdrawal must be
received by the exchange agent prior to 5:00 p.m., New York City time on the
business day prior to the expiration date at the

                                       29
<PAGE>
address set forth below under "--Exchange Agent" and prior to acceptance for
exchange thereof by the Company. Any such notice of withdrawal must:

    1.  specify the name of the person having tendered the initial notes to be
       withdrawn (the "Depositor");

    2.  identify the initial notes to be withdrawn, including, if applicable,
       the registration number or numbers and total principal amount of such
       initial notes;

    3.  be signed by the Depositor in the same manner as the original signature
       on the letter of transmittal by which such initial notes were tendered
       (including any required signature guarantees) or be accompanied by
       documents of transfer sufficient to permit the Trustee with respect to
       the initial notes to register the transfer of such initial notes into the
       name of the Depositor withdrawing the tender;

    4.  specify the name in which any such initial notes are to be registered,
       if different from that of the Depositor; and

    5.  if the initial notes have been tendered pursuant to the book-entry
       procedures, specify the name and number of the participant's account at
       DTC to be credited, if different than that of the Depositor.

    All questions as to the validity, form and eligibility, time of receipt of
such notices will be determined by us, whose determination shall be final and
binding on all parties. Any initial notes so withdrawn will be deemed not to
have been validly tendered for exchange for purposes of the exchange offer. Any
initial notes that have been tendered for exchange and that are not exchanged
for any reason will be returned to the holder thereof without cost to such
holder (or, in the case of initial notes tendered by book-entry transfer, such
initial notes will be credited to an account maintained with the Book-Entry
Transfer Facility for the initial notes) as soon as practicable after
withdrawal, rejection of tender or termination of the exchange offer. Properly
withdrawn initial notes may be re-tendered by following one of the procedures
described under "--Procedures for Tendering" and "--Book-Entry Transfer" above
at any time on or prior to the expiration date.

    CONDITIONS

    Notwithstanding any other term of the exchange offer, initial notes will not
be required to be accepted for exchange, nor will exchange notes be issued in
exchange for any initial notes, and we may terminate or amend the exchange offer
as provided herein before the acceptance of such initial notes if:

    1.  because of any change in law, or applicable interpretations thereof by
       the SEC, we determine that we are not permitted to effect the exchange
       offer;

    2.  an action or proceeding is commenced or threatened that would materially
       impair our ability to proceed with the exchange offer; or

    3.  not all government approvals that we deem necessary for the consummation
       of the exchange offer have been received.

    We have no obligation to, and will not knowingly, permit acceptance of
tenders of initial notes:

    - from our affiliates within the meaning of Rule 405 under the Securities
      Act;

    - from any other holder or holders who are not eligible to participate in
      the exchange offer under applicable law or interpretations by the SEC; or

    - if the exchange notes to be received by such holder or holders of initial
      notes in the exchange offer, upon receipt, will not be tradable by such
      holder without restriction under the Securities

                                       30
<PAGE>
      Act and the Exchange Act and without material restrictions under the "blue
      sky" or securities laws of substantially all the states of the United
      States.

    ACCOUNTING TREATMENT

    The exchange notes will be recorded at the same carrying value as the
initial notes, as reflected in our accounting records on the date of the
exchange. Accordingly, no gain or loss for accounting purposes will be
recognized by us. The costs of the exchange offer and the unamortized expenses
related to the issuance of the initial notes will be amortized over the term of
the exchange notes.

    EXCHANGE AGENT

    Firstar Bank, N.A. has been appointed as exchange agent for the exchange
offer. Questions and requests for assistance and requests for additional copies
of this prospectus or of the letter of transmittal should be directed to the
exchange agent addressed as follows:

       By Mail, Overnight Mail or Courier:
       Firstar Bank, N.A.
       425 Walnut Street,
       Corporate Trust Services, 6(th) Floor
       Cincinnati, OH 45202
       ATTN: Keith Maurmeier

       Facsimile Transmission: (513) 632-5511
       Confirm by Telephone: (513) 632-4843

    FEES AND EXPENSES

    We will pay the expenses of soliciting tenders under the exchange offer. The
principal solicitation for tenders pursuant to the exchange offer is being made
by mail; however, additional solicitations may be made by telegraph, telephone,
telecopy or in person by our officers and regular employees.

    We will not make any payments to brokers, dealers or other persons
soliciting acceptances of the exchange offer. We, however, will pay the exchange
agent reasonable and customary fees for its services and will reimburse the
exchange agent for its reasonable out-of-pocket expenses in connection
therewith. We may also pay brokerage houses and other custodians, nominees and
fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding
copies of the prospectus, letters of transmittal and related documents to the
beneficial owners of the initial notes, and in handling or forwarding tenders
for exchange.

    The expenses to be incurred in connection with the exchange offer will be
paid by us, including fees and expenses of the exchange agent and Trustee and
accounting, legal, printing and related fees and expenses.

    We will pay all transfer taxes, if any, applicable to the exchange of
initial notes pursuant to the exchange offer. If, however:

    - certificates representing exchange notes or initial notes for principal
      amounts not tendered or accepted for exchange are to be delivered to, or
      are to be registered or issued in the name of, any person other than the
      registered holder of the initial notes tendered; or

    - if tendered initial notes are registered in the name of any person other
      than the person signing the letter of transmittal; or

    - if a transfer tax is imposed for any reason other than the exchange of
      initial notes pursuant to the exchange offer,

then the amount of any such transfer taxes, whether imposed on the registered
holder or any other persons, will be payable by the tendering holder. If
satisfactory evidence of payment of such taxes or

                                       31
<PAGE>
exemption therefrom is not submitted with the letter of transmittal, the amount
of the transfer taxes will be billed directly to the tendering holder.

                                USE OF PROCEEDS

    There will be no cash proceeds payable to us from the issuance of the
exchange notes under the exchange offer. In consideration for issuing the
exchange notes as contemplated in this prospectus, we will receive initial notes
in like principal amount, the terms of which are identical in all material
respects to the exchange notes. The initial notes surrendered in exchange for
the exchange notes will be retired and canceled and cannot be reissued.
Accordingly, the issuance of the exchange notes will not result in any increase
in our indebtedness. The proceeds received from the sale of the initial notes
were used to redeem some limited partnership interests in LaBranche & Co.,
redeem membership interests in LaB Investing Co. L.L.C. and repay some
subordinated indebtedness.

                    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, our subsidiary, LaBranche & Co. is 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

                                       35
<PAGE>
among our managing directors based on their respective percentage interests in
the profits of LaB 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 our initial note offering and our
common stock offering.

    REORGANIZATION

    We incurred indebtedness of approximately $116.4 million through our initial
note offering and the simultaneous issuance of subordinated indebtedness 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 the
reorganization and related issuances of indebtedness is higher than historical
levels.

    The redemption of the limited partners' interests was accounted for as a
step acquisition under the purchase method of accounting. The pro forma excess
of purchase price over the limited partners' capital accounts of $127.3 million
was allocated to intangible assets. Accordingly, amortization of intangible
assets is expected to increase in the future.

    INCOME TAXES

    As a partnership, we were generally not subject to U.S. federal, state and
local income taxes, apart from the 4% New York City unincorporated business tax.
As part of our restructuring to a corporation, we are subject to U.S. federal,
state and local income taxes. 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 primarily due to the Fowler, Rosenau
acquisition, under which we became the specialist for 76 additional common stock
listings, and was due also to increased share volume as

                                       37
<PAGE>
principal in our existing specialist stocks traded on the NYSE. Our share volume
as principal increased 97.3% 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 73.6% to
2.0 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
due to net gains in proprietary trading of non-specialist securities.

    EXPENSES

    Total expenses before managing directors' compensation, limited partners'
interest in earnings of subsidiary and unincorporated business taxes increased
67.4% to $24.1 million for the period ended June 30, 1999 from $14.4 million for
the same period in 1998.

    Employee compensation and related expenses increased 116.1% to $11.3 million
for the six months ended June 30, 1999, from $5.2 million for the same period in
1998. Our number of employees increased to 161 as of June 30, 1999, from 107 as
of June 30, 1998, primarily due to the Fowler, Rosenau acquisition. As a
percentage of total revenues, employee compensation increased to 10.9% of total
revenues for the six months ended June 30, 1999, from 10.0% of total revenues
for the same period in 1998.

    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
32 to 44, 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
June 30, 1999, from $1.5 million for the same period in 1998. This increase was
primarily due to an increase in outstanding subordinated indebtedness of $15.0
million on June 30, 1998.

    Exchange, clearing and brokerage fees consist primarily of fees paid by us
as a specialist to the NYSE and to clearing houses. Fees paid by us to the NYSE
include primarily fees based on the volume of transactions executed as principal
and as agent, as well as a flat annual fee. Exchange, clearing and brokerage
fees expense increased 46.8% to $2.0 million for the six months ended June 30,
1999, from $1.4 million for the same period in 1998. This increase was primarily
attributable to an increase in share volume.

executive offices and our space on the NYSE floor, and depreciation on leasehold
improvements. Occupancy expense

                                       38
<PAGE>
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 was primarily the result of
the expansion of our business.

    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
retrieval and informational services utilized due to the growth of our business.

    Legal and professional fees increased 75.8% to $466,000 for the six months
ended June 30, 1999, from $265,000 for the same period in 1998.

    Other expenses decreased 34.0% to $1.1 million for the six months ended June
30, 1999, from $1.6 million for the same period in 1998. This was the result of
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
in earnings of subsidiary and unincorporated business taxes increased 110.4% to
$79.3 million for the six months ended June 30, 1999, from $37.7 million for the
same period in 1998.

    Managing directors' compensation increased 103.2% to $48.2 million for the

    Unincorporated business tax expense increased 99.4% to $3.8 million for the
six months ended June 30, 1999, from $1.9 million for the same period in 1998 as
a result of increased profitability of the firm.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

    REVENUES

    Total revenues increased 86.9% to $126.4 million for 1998 from $67.6 million
for 1997, due primarily to the increase in revenue from net gain on principal
transactions. Net gain on principal transactions increased 98.8% to $95.0
million for 1998, from $47.8 million for 1997. This increase was primarily due
to an increase in share volume. This increase in share volume, 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 listing due to the Fowler, Rosenau acquisition. Our share volume as
principal increased 134.4% to 5.9 billion shares for 1998, from 2.5 billion
shares for 1997.

    Commissions revenue increased 75.0% to $26.6 million for 1998 from $15.2
million for 1997. This increase was due to an increase in share volume in which

volume 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. The share volume executed by us as agent in our specialist
stocks increased 70.6% to 2.9 billion shares for 1998, from 1.7 billion shares
for 1997.

    Other revenue increased 3.2% to $4.8 million for the twelve months ended

revenues for 1997.

    Severance expense was $0 in 1998 and $300,000 in 1997. We incurred severance
expense during 1997 as a result of a subsequent change in the retirement package
of one of our senior managing directors who retired in 1996.

    Lease of exchange membership expense increased 76.2% to $6.6 million for
1998, from $3.7 million for 1997. This increase was due to the increase in the

we obtained to comply with data processing testing required by the NYSE in
anticipation of the acquisition.

YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

    REVENUES

    Total revenues increased 35.5% to $67.6 million for 1997 from $49.9 million
for 1996, principally due to the increase in revenue from principal
transactions, net. Net gain on principal transactions increased 28.8% to $47.8
million for 1997, from $37.1 million for 1996. 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 to our acquisitions of Ernst and Stern, under which
we became the specialist for 55 additional common stock listings, and was also
due to increased share volume as principal in our existing specialist stocks
traded on the NYSE. Our share volume as principal increased 106.3% to 2.5
billion shares for 1997, from 1.2 billion shares for 1996.

    Commissions revenue increased 49.2% to $15.2 million for 1997, from $10.2
million for 1996. This increase was primarily due to increased share volume in
which we acted as an agent. This increase, in turn, resulted from the increase
in number of common stock listings due to the Stern and Ernst acquisitions, 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 45.5% to 1.7 billion shares for 1997, from 1.2 billion shares for
1996.

    Other revenue increased 75.4% to $4.6 million for 1997, from $2.6 million

Stern acquisitions. As a percentage of total revenues, employee compensation
increased to 12.0% of total revenues for 1997, from 11.5% of total revenues for
1996.

    Severance expense decreased 94.4% to $300,000 in 1997 from $5.4 million in
1996. This decrease was due to the retirement of two of our senior managing
directors in 1996.

    Lease of exchange membership expense increased 51.0% to $3.7 million for
1997, from $2.5 million for 1996. This increase was due to the increase in the

LIQUIDITY

    Prior to our initial note offering and our common stock offering we had
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 and
would bear interest at The Bank of New York's broker loan rate. 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
$171,000.

    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

                                       42
<PAGE>
extend the maturities for an additional year, unless the lender provides notice
at least seven months prior to maturity. Concurrently with our initial note
offering and our common stock offering, we repaid $5.0 million of the junior
subordinated debt as part of the reorganization of our firm from partnership to
corporate form.

    Concurrently with our initial note offering and our common stock offering,
we paid $149.2 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. At
approximately the same time as our initial note offering and our common stock
offering, we issued a $16.0 million note 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 bears
interest at the annual rate of 9.5%. LaBranche & Co. also entered into a
$350,000 cash subordinated loan agreement, bearing interest at an annual rate of
8.0%, as payment for the acquisition of a limited partnership interest. In
addition, we repaid $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 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 our initial note offering,
our common stock 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, please 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 21st century dates
and 20th 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 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.

                                       44

    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

    - a 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, our subsidiary, LaBranche & Co. is 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 43 new listed companies, resulting from 67 listing interviews.
In addition, we have acquired three specialist operations since 1997, adding 131
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 71 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.

    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.

    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.

                                       47
<PAGE>
    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 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;

                                       48
<PAGE>
    - 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 84.1% 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 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

                                       49
<PAGE>
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 82.8% to 84.1% for the past five years. It is unclear, however, how the
alternative trading methods and new technologies just described or that may be
developed will affect the percentage of trading in listed stocks conducted on
the NYSE. The NYSE has indicated that it is studying the possibility of
embracing electronic communications network technology to expand trading. ATSs
may be developed, organized and operated by large brokerage houses and
investment banks with greater capital, better access to technology and direct
access to investors. As a result, these parties may be well positioned to direct
trading to these networks. These alternative trading methods may account for a
growing percentage of the trading volume of NYSE-listed stocks.

    The accelerating growth of trading volume and the increase in stock prices
on the NYSE in the 1990s has increased the demands upon specialists. In order to
fulfill their obligations, specialists are required to execute a greater number
of trades in a shorter period of time with greater price volatility. In
addition, specialists are called upon to take larger positions in their
specialist stocks. These factors have led to a consolidation of specialist units
in the past five years. 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. 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.

    - 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

                                       50
<PAGE>
      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 67 selection pools for listed
      companies and were chosen by management of the listed companies in 43 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 our
      initial note offering and our common stock offering, we 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 our initial note offering and our common stock offering,
    our working capital increased from $123.7 million to $201.7 million. In
    selecting a specialist firm, listed companies often focus on the capital
    resources of the specialist, especially more recently as trading volumes

                                       51
<PAGE>
    have increased. We 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. LLC., 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 36 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

                                       52
<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

                                       53
<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.

                                       54

    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.

                                       55
<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 $1.5 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 Chairman, Chief Executive
      Officer and President.

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

                                       56

the NYSE. The following is a list of our top 50 listed companies in terms of

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.

                                       57
<PAGE>
    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 this
rule, 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 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.

                                       58
<PAGE>
    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.

    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 our initial note offering
and our common stock offering, three of our managing directors retired 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.

Mr. Naughton has been a specialist with LaBranche & Co. since 1979 and was
appointed to the executive operating committee of LaBranche & Co. in 1990.

BOARD COMMITTEES

    The audit committee of our board of directors will be established as soon as
practicable 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 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.

                                       61
<PAGE>
    The compensation committee of our board of directors will be established as
soon as practicable 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. It is
anticipated that non-employee directors will receive an annual retainer,
attendance fees for board and 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 our
initial note offering and our common stock offering, we 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 our
initial note offering and our common stock offering.

    The following table sets forth the annual salary we intend to pay during
fiscal 1999 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., exchanged their membership interests in LaB Investing Co. L.L.C. for
shares of our common stock. We have entered into employment agreements, pledge
agreements and agreements regarding noncompetition and other covenants with all
members who continue as managing directors after our common stock offering,
including 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 reasonable 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 our
common stock 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.

                                       63
<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 securities 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 our
common stock 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 our common stock 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 our common stock
      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 became effective prior to the closing of our
common stock offering. You should, however, refer to the exhibits that are a
part of the registration statement relating to our common stock offering for a
copy of the Equity Incentive Plan. See "Available Information."

    Immediately prior to the closing of our common stock offering, we granted
(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 our employees who are not
managing directors. Subject to continuing service with the firm and certain
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 the 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 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, currently administered by our
board of directors, will be administered by the compensation committee of our
board of directors once the compensation committee is established. 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.

                                       65
<PAGE>
    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 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.

                                       66
<PAGE>
    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 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 at 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 adopted, effective upon the closing of our common
stock 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 our common stock 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

                                       67
<PAGE>
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.

                             PRINCIPAL STOCKHOLDERS

    The following table presents information about the beneficial ownership of
our common stock by:

    - each person known to beneficially own more than 5.0% of the outstanding
      shares of common stock;

    - each of our directors;

    - each named executive officer;

    - and all executive officers and directors as a group.

All persons listed have sole voting and investment power with respect to their
shares unless otherwise indicated. Unless otherwise indicated, the address of
the beneficial owners is: c/o One Exchange Plaza, New York, New York, 10006.
Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission and generally includes voting or investment
power with respect to securities. Shares of common stock issuable pursuant to
options, to the extent such options are currently exercisable or convertible
within 60 days of September 29, 1999, are treated as outstanding for computing
the percentage of the person holding such securities but are not treated as
outstanding for computing the percentage of any other person.

(1) Each of our managing directors, including all our executive officers, has
    entered into a stockholders' agreement, the terms of which are described
    under "Certain Transactions-- Reorganization and Related
    Transactions--Stockholders' Agreement." Messrs. LaBranche, Gallagher and
    Hayward beneficially own an aggregate of 7,696,262 shares of common stock,
    constituting approximately 16.8% of the outstanding shares of common stock.
    As a result of the stockholders' agreement, Messrs. LaBranche, Gallagher and
    Hayward, acting together as a group, may be deemed to beneficially own an
    aggregate of 34,686,343 shares of common stock (including the 7,696,262
    shares beneficially owned by them individually), constituting approximately
    75.6% of the outstanding shares of common stock. Each of Messrs. LaBranche,
    Gallagher and Hayward disclaims beneficial ownership of any and all shares
    of common stock held by any person or entity other than him.

                              CERTAIN TRANSACTIONS

REORGANIZATION AND RELATED TRANSACTIONS

REORGANIZATION

    Concurrently with our initial note offering and our common stock offering,
we completed a number of transactions in order to effect the reorganization of
our firm from partnership to corporate form. These transactions are summarized
below:

    - The 36 members of LaB Investing Co. L.L.C. exchanged their membership
      interests in LaB Investing Co. L.L.C. which represented a 69.8% interest
      in the profit of LaBranche & Co. for an aggregate of 34,816,334 shares of
      our common stock. In addition to receiving a portion of those shares,
      three members of LaB Investing Co. L.L.C. also received an aggregate of
      $9.0 million in cash as part of their exchange. All members who have
      remained employed by us following our common stock offering only received
      shares of our common stock, and no cash, in the reorganization. We thus
      became the sole member of LaB Investing Co. L.L.C., and LaB Investing Co.
      L.L.C. continues to be the general partner of LaBranche & Co. Our common
      stock received by the members of LaB Investing Co. L.L.C. is subject to
      certain restrictions, as described below under "--Stockholders'

    - The 19 limited partners of LaBranche & Co., other than Mill Bridge, Inc.,
      exchanged their limited partnership interests in LaBranche & Co. which
      represented a 16.0% interest in the profits of LaBranche & Co. to us in
      exchange for an aggregate of $66.2 million in cash, 558,666 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 are subject to lock-up restrictions which prohibits the
      transfer of 50% of those shares for a period of one year and the remaining
      50% for a period of two years following our common stock offering.

    - Mill Bridge, Inc., a subsidiary of Van der Moolen Holding NV, received
      $90.0 million from us, including $74.0 million in cash and our 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. In addition, we repaid $5.0 million of subordinated debt
      to an affiliate of Van der Moolen.

    - As a result of the above transactions, we became 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 our common stock offering, we granted
      options under the Equity Incentive Plan to purchase an aggregate of
      1,200,000 shares of our common stock to our executive officers. The
      options have an exercise price of $14, the initial public offering price
      of our common stock, and are not currently exercisable.

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

    - Prior to the closing of our common stock offering, we completely
      discharged 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 were 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 entered into a stockholders' agreement with all 36 members of LaB
Investing Co. L.L.C. who received our common stock in the reorganization, 33 of
whom remain managing directors following our common stock offering, and with the
employees who received options and restricted stock or restricted stock unit
awards in connection with the reorganization. This stockholders' agreement
contains various restrictions on the transfer of our stock by the parties to
such agreement and a voting agreement.

    TRANSFER RESTRICTIONS.  The stockholders' agreement prohibits the transfer
of our shares by the former members of LaB Investing Co. L.L.C. who remain
managing directors following our common stock offering for a period of three
years. Beginning on the third anniversary of our common stock 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.
In addition, the former members of LaB Investing Co. L.L.C. who did not continue
as managing directors after our common stock offering are restricted from
transferring shares as follows:

    - 50% of the shares will be transferable after the first anniversary of our
      common stock offering; and

    - all of the shares will be transferable after the second anniversary of our
      common stock offering.

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 CAPITAL

    The members of LaB Investing Co. L.L.C. have historically contributed
capital to LaB Investing Co. L.L.C., which was, in turn, contributed to

INTEREST ON INDEBTEDNESS

    A family member of Mr. Flaherty holds $600,000 of subordinated indebtedness
due August 31, 2000 and Mr. LaBranche's spouse holds $1.3 million of secured
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 EXCHANGE NOTES

    The initial notes were, and the exchange notes will be, issued under an
indenture (the "Indenture") dated as of August 24, 1999 by and among the Company
and Firstar Bank, NA., as Trustee (the "Trustee"). The following is a summary of
the material provisions of the Indenture. It does not include all of the
provisions of the Indenture. We urge you to read the Indenture because it
defines your rights. The terms of the exchange notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (the "TIA"). A copy of the Indenture may be
obtained from the Company.

    You can find definitions of certain capitalized terms used in this
description under "--Certain Definitions." When we refer to the "Company" in
this section, we mean only LaBranche & Co Inc. and not its Subsidiaries.

OVERVIEW OF THE EXCHANGE NOTES

    The exchange notes will:

    - be general unsecured senior obligations of the Company;

    - rank equal in right of payment with all other existing and future senior
      unsecured obligations of the Company;

    - rank senior in right of payment to all existing and future subordinated
      indebtedness of the Company, if any;

    - be effectively subordinated to all existing and future secured
      indebtedness of the Company; and

    - not be guaranteed by any Subsidiary of the Company and therefore will be
      effectively subordinated to all existing and future indebtedness of the
      Company's Subsidiaries.

    As of June 30, 1999, on a pro forma basis as described in the pro forma
consolidated financial information included in this prospectus (excluding
subordinated liabilities related to contributed exchange memberships):

    - the Company and its Subsidiaries would have had consolidated long-term
      indebtedness of $162.5 million;

    - the Company would have had long-term indebtedness of $116.0 million, none
      of which would have been secured; and

    - Subsidiaries of the Company would have had long-term indebtedness of $46.5
      million, excluding any intercompany indebtedness.

PRINCIPAL, MATURITY AND INTEREST

    The exchange notes will be limited to $100.0 million aggregate principal
amount. The exchange notes will mature on August 15, 2004. Interest on the
exchange notes will accrue at the rate of 9 1/2% per annum and will be payable
semiannually in cash on each February 15 and August 15 to the persons who are
registered holders of the exchange notes (the "Holders") at the close of
business on the February 1 and August 1 immediately preceding the applicable
interest payment date. Interest on the exchange notes, will accrue from and
including the most recent date to which interest has been paid on the initial
notes or, if no interest has been paid on the initial notes, from and including
the date of issuance of the initial notes.

    The exchange notes will be issued in fully registered form only, without
coupons, in denominations of $1,000 and integral multiples thereof. Initially,
the Trustee will act as paying agent and registrar for the exchange notes. The
exchange notes may be presented for registration or transfer and exchange at

                                       72
<PAGE>
the offices of the registrar, which initially will be the Trustee's corporate
trust office. The Company may change any paying agent and registrar without
notice to the Holders.

    The Company will pay principal (and premium, if any) on the exchange notes
at the Trustee's corporate office in New York, New York. At the Company's
option, interest may be paid at the Trustee's corporate trust office or by check
mailed to the registered address of the Holders.

    The exchange notes will not be entitled to the benefit of any mandatory
sinking fund.

OPTIONAL REDEMPTION

    The Company may redeem the exchange notes, at its option, in whole or in
part at any time, at a redemption price equal to the principal amount of the
exchange notes redeemed plus the Make-Whole Premium as of the date of
redemption. The Company will also pay accrued and unpaid interest on the
exchange notes redeemed.

    In the event that less than all of the exchange notes are to be redeemed at
any time, selection of the exchange notes for redemption will be made by the
Trustee either:

    (1) in compliance with the requirements of the principal national securities
       exchange, if any, on which the exchange notes are listed; or

    (2) if the exchange notes are not then listed on a national securities
       exchange, on a pro rata basis, by lot or by such method as the Trustee
       shall deem fair and appropriate.

    No exchange notes of a principal amount of $1,000 or less shall be redeemed
in part.

    Notice of redemption shall be mailed by first-class mail at least 30 but not
more than 60 days before the Redemption Date to each Holder of exchange notes to
be redeemed at its registered address. If any exchange note is to be redeemed in
part only, the notice of redemption that relates to such exchange note shall
state the portion of the principal amount thereof to be redeemed. A new exchange
note in a principal amount equal to the unredeemed portion thereof will be
issued in the name of the Holder thereof upon cancellation of the original
exchange note. On and after the date of redemption, interest will cease to
accrue on exchange notes or portions thereof called for redemption as long as
the Company has deposited with the paying agent funds in satisfaction of the
applicable redemption price pursuant to the Indenture.

CHANGE OF CONTROL

    Upon the occurrence of a Change of Control, each Holder will have the right
to require that the Company purchase all or a portion of such Holder's exchange
notes pursuant to the offer described below (the "Change of Control Offer"), at
a purchase price equal to 101% of the principal amount thereof plus accrued
interest, if any, thereon to the date of purchase.

    Within 30 days following the date upon which the Change of Control occurs,
the Company must send, by first class mail, a notice to each Holder, with a copy
to the Trustee, which notice shall govern the terms of the Change of Control
Offer. Such notice shall state, among other things, the purchase date, which
must be no earlier than 30 days nor later than 60 days from the date such notice
is mailed, other than as may be required by law (the "Change of Control Payment
Date"). Holders electing to have an exchange note purchased pursuant to a Change
of Control Offer will be required to surrender the note, with the form entitled
"Option of Holder to Elect Purchase" on the reverse of the exchange note
completed, to the Paying Agent at the address specified in the notice prior to
the close of business on the third business day prior to the Change of Control
Payment Date.

    If a Change of Control Offer is required to be made, there can be no
assurance that the Company will be permitted by the terms of the Credit
Agreement or other Indebtedness of the Company to

                                       73
<PAGE>
make such a Change of Control Offer or that it will have available funds
sufficient to pay the Change of Control purchase price for all the exchange
notes that might be delivered by Holders seeking to accept the Change of Control
Offer. A Change of Control may be a default under the Credit Agreement. In the
event the Company is required to purchase outstanding exchange notes pursuant to
a Change of Control Offer, the Company expects that it would seek third party
financing to the extent it does not have available funds to meet its purchase
obligations. However, there can be no assurance that the Company would be able
to obtain such financing.

    Neither the Board of Directors of the Company nor the Trustee may waive the
covenant relating to a Holder's right to require the purchase of exchange notes
upon a Change of Control. Restrictions in the Indenture on the ability of the
Company and the Restricted Subsidiaries to incur additional Indebtedness, to
grant liens on its property, to make Restricted Payments and to make Asset Sales
may also make more difficult or discourage a takeover of the Company, whether
favored or opposed by the management of the Company. Consummation of any such
transaction in certain circumstances may require the purchase of the exchange
notes, and there can be no assurance that the Company or the acquiring party
will have sufficient financial resources to effect such purchase. Such
restrictions and the restrictions on transactions with Affiliates may, in
certain circumstances, make more difficult or discourage any leveraged buyout of
the Company or any of its Subsidiaries by the management of the Company. While
such restrictions cover a wide variety of arrangements which have traditionally
been used to effect highly leveraged transactions, the Indenture may not afford
the Holders of exchange notes protection in all circumstances from the adverse
aspects of a highly leveraged transaction, reorganization, restructuring, merger
or similar transaction.

    The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with a Change of
Control Offer. To the extent that the provisions of any securities laws or
regulations conflict with the "Change of Control" provisions of the Indenture,
the Company shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the "Change of
Control" provisions of the Indenture by virtue thereof.

CERTAIN COVENANTS

    The Indenture contains, among others, the following covenants:

    LIMITATION ON INCURRENCE OF ADDITIONAL INDEBTEDNESS

    The Company will not, and will not permit any of the Restricted Subsidiaries
to, directly or indirectly, Incur any Indebtedness, other than Permitted
Indebtedness; provided, however, that if no Default or Event of Default shall
have occurred and be continuing at the time of or as a consequence of the
Incurrence of any such Indebtedness, the Company may Incur Indebtedness and the
Restricted Subsidiaries may Incur Acquired Indebtedness, in each case if on the
date of the Incurrence of such Indebtedness, after giving effect to the
Incurrence thereof, the Consolidated Fixed Charge Coverage Ratio of the Company
is greater than 2.75 to 1.

    LIMITATION ON RESTRICTED PAYMENTS

    The Company will not, and will not cause or permit any of the Restricted
Subsidiaries to, directly or indirectly:

       dividends or distributions payable in Qualified Capital Stock of the
       Company, on or in respect of shares of the Company's Capital Stock;

<PAGE>

       otherwise acquire or retire for value, any Indebtedness which is

       of interest or any principal payment at the Stated Maturity thereof;

    (d) make any Investment, other than a Permitted Investment; or

    (e) make compensation or consulting payments (in excess of base salaries
       limited to $250,000) to managing directors and other executive officers
       (as defined in Rule 3b-7 under the Exchange Act) of the Company or any of
       its Restricted Subsidiaries, except to the extent authorized under the
       Annual Incentive Plan or the Equity Incentive Plan or otherwise approved
       by a majority of the disinterested members of the Board of Directors of
       the Company or a duly authorized committee thereof who are not managing
       directors or other executive officers of the Company or any of its
       Affiliates;

(each of the foregoing actions set forth in clauses (a), (b), (c), (d) and (e)

           continuing; or

       (2) the Company is not able to incur at least $1.00 of additional

           Additional Indebtedness"; or

       (3) the aggregate amount of Restricted Payments, including the proposed
           Restricted Payment, made subsequent to the Issue Date (the amount
           expended for such purpose, if other than in cash, being the fair
           market value of such property as determined reasonably and in good
           faith by the Board of Directors of the Company) shall exceed the sum
           of:

           (A) 50% of the cumulative Consolidated Net Income (or if cumulative
               Consolidated Net Income shall be a loss, minus 100% of such loss)
               of the Company earned from the beginning of the first full fiscal
               quarter following the Issue Date and through the end of the most
               recent fiscal quarter for which financial statements are
               available prior to the date such Restricted Payment occurs (the
               "Reference Date"), treating such period as a single accounting
               period; plus

           (B) 100% of the aggregate net cash proceeds received by the Company
               from any Person, other than a Subsidiary of the Company, from the
               issuance and sale subsequent to the Issue Date and on or prior to
               the Reference Date of Qualified Capital Stock of the Company or
               of other securities that have been converted into Qualified
               Capital Stock of the Company; plus

           (C) without duplication of any amounts included in clause (3)(B)
               above, 100% of the aggregate net cash proceeds of any
               contribution to the common equity capital of the Company received
               by the Company from a holder of the Company's Qualified Capital
               Stock,

           excluding, in the case of clauses (3)(B) and (C), any net proceeds
           from a sale of Qualified Capital Stock received from a Subsidiary of
           the Company or applied in accordance with clause (2)(b) of the
           immediately following paragraph; plus

                                       75
<PAGE>
           (D) an amount equal to the lesser of:

               - the sum of the fair market value of the Capital Stock of an
                 Unrestricted Subsidiary owned by the Company and/or the
                 Restricted Subsidiaries and the aggregate amount of all
                 Indebtedness of such Unrestricted Subsidiary owed to the
                 Company and each Restricted Subsidiary on the date of
                 Revocation of such Unrestricted Subsidiary as an Unrestricted
                 Subsidiary in accordance with the covenant described under
                 "--Limitation on Designations of Unrestricted Subsidiaries";
                 and

               - the Designation Amount treated as a Restricted Payment pursuant
                 to clause (d) above with respect to such Unrestricted
                 Subsidiary on the date of the Designation of such Subsidiary as
                 an Unrestricted Subsidiary in accordance with the covenant
                 described under "--Limitation on Designations of Unrestricted
                 Subsidiaries"; plus

           (E) in the case of the disposition of an Investment treated as a
               Restricted Payment pursuant to clause (d) above to a Person other
               than the Company or one of its Subsidiaries, an amount equal to
               the lesser of:

               - the amount of such Investment treated as a Restricted Payment
                 pursuant to clause (d) above, and

               - the amount in cash received by the Company or any Restricted
                 Subsidiary upon such disposition; plus

           (F) $10.0 million.

    The provisions set forth in the immediately preceding paragraph do not
prohibit:

       (1) the payment of any dividend within 60 days after the date of
           declaration of such dividend if the dividend would have been
           permitted on the date of declaration;

       (2) the redemption, repurchase, retirement, defeasance or other
           acquisition of Indebtedness of the Company or any Restricted
           Subsidiary or of Capital Stock of the Company, in each case to the
           extent constituting a Restricted Payment pursuant to clause (b) or
           (c) of the first paragraph of this covenant either:

           (a) solely in exchange for shares of Qualified Capital Stock of the
               Company, or

           (b) through the application of net proceeds of a substantially
               concurrent sale for cash (other than to a Subsidiary of the
               Company) of shares of Qualified Capital Stock of the Company or
               of any contribution to the common equity capital of the Company
               received by the Company from a holder of the Company's Qualified
               Capital Stock;

       (3) the defeasance, redemption, repurchase or other acquisition of
           Indebtedness of the Company or any Restricted Subsidiary with the net
           cash proceeds from an Incurrence of Permitted Refinancing
           Indebtedness therefor; and

       (4) so long as no Default or Event of Default shall have occurred and be
           continuing, repurchases of Capital Stock (or options therefor) of the
           Company from officers, directors, employees, consultants or former
           officers, directors, employees or consultants of the Company (or any
           of its Subsidiaries) pursuant to equity ownership or compensation
           plans or stockholders agreements not to exceed $5.0 million in any
           year.

In determining the aggregate amount of Restricted Payments made subsequent to
the Issue Date in accordance with clause (3) of the immediately preceding
paragraph, amounts expended pursuant to clauses (1) and (4) of this paragraph
shall be included in the calculation.

    LIMITATION ON ASSET SALES

    The Company will not, and will not permit any of the Restricted Subsidiaries
to, consummate an Asset Sale unless:

       (1) the Company or the applicable Restricted Subsidiary, as the case may
           be, receives consideration at the time of the Asset Sale at least
           equal to the fair market value of the assets sold or otherwise
           disposed of as determined in good faith by the Board of Directors of
           the Company;

       (2) at least 75% of the consideration received by the Company or the
           Restricted Subsidiary, as the case may be, from the Asset Sale shall
           be in the form of cash or Cash Equivalents and is received at the
           time of such Asset Sale; and

       (3) upon the consummation of each Asset Sale, the Company applies, or
           causes such Restricted Subsidiary to apply, the Net Cash Proceeds
           relating to such Asset Sale within 360 days of receipt thereof
           either:

           (a) to repay any Indebtedness of the Company to the extent secured by
               a Lien pursuant to clause (a), (b), (c), (d), (e) or (h) of
               "--Limitation on Liens," and effect a permanent reduction in the
               availability in respect of the Indebtedness (without refinancing
               the Indebtedness);

           (b) to repay any Indebtedness of a Wholly Owned Restricted Subsidiary
               owed to any Person other than the Company or any of its
               Affiliates and effect a permanent reduction in any availability
               in respect of the Indebtedness(without refinancing the
               Indebtedness);

           (c) to acquire Replacement Assets; or

           (d) a combination of prepayment and investment permitted by the
               preceding clauses (3)(a), (b) and (c).

The assumption by the transferee in an Asset Sale (and release of the Company
and its Restricted Subsidiaries of further liability) of Indebtedness for
borrowed money of the Company or any Restricted Subsidiary other than
Disqualified Capital Stock or Indebtedness subordinated in right of payment to
the exchange notes shall be deemed to be cash applied in accordance with this
covenant. The receipt by the Company or the applicable Restricted Subsidiary of
marketable securities of a company subject to and then current in its
obligations as a reporting company under Section 13 or 15 under the Exchange
Act, which are resold for cash or Cash Equivalents by the Company or the
Restricted Subsidiary within 120 days of the relevant Asset Sale and applied in
accordance with this covenant, shall be deemed to be cash received pursuant to
clause (2) above.

    On the 361st day after an Asset Sale or such earlier date, if any, as the
Board of Directors of the Company or of such Restricted Subsidiary determines
not to apply the Net Cash Proceeds relating to the Asset Sale as set forth in
clause (3) of the immediately preceding paragraph (each, a "Net Proceeds Offer
Trigger Date"), the aggregate amount of Net Cash Proceeds that have not been
applied on or before the Net Proceeds Offer Trigger Date as permitted in that
clause (3) (a "Net Proceeds Offer Amount") shall be applied by the Company to
make an offer to purchase (the "Net Proceeds Offer") on a date (the "Net
Proceeds Offer Payment Date") not less than 30 nor more than 60 days following
the Net Proceeds Offer Trigger Date, from all Holders on a pro rata basis, that
principal amount of exchange notes equal to the Net Proceeds Offer Amount at a
price equal to 100% of the principal amount of the exchange notes to be
purchased, plus accrued and unpaid interest, if any, thereon to the date of
purchase; provided that the Company may make a concurrent offer to repurchase on
a pro rata basis Indebtedness of a Wholly Owned Restricted Subsidiary or
Indebtedness of the Company ranking PARI PASSU with the exchange notes.

                                       77
<PAGE>
    If at any time any non-cash consideration received by the Company or any
Restricted Subsidiary, as the case may be, in connection with any Asset Sale is
converted into or sold or otherwise disposed of for cash (other than interest
received with respect to any such non-cash consideration) or Cash Equivalents,
then such conversion or disposition shall be deemed to constitute an Asset Sale
hereunder and the Net Cash Proceeds thereof shall be applied in accordance with
this covenant. Pending application in accordance with this covenant, Net Cash
Proceeds may be used to repay revolving credit borrowings without reducing
commitments thereunder.

    The Company may defer the Net Proceeds Offer until there is an aggregate
unutilized Net Proceeds Offer Amount equal to or in excess of $5.0 million
resulting from one or more Asset Sales or deemed Asset Sales (at which time, the
entire unutilized Net Proceeds Offer Amount, and not just the amount in excess
of $5.0 million, shall be applied as required pursuant to this paragraph).

    In the event of the transfer of substantially all (but not all) of the
property and assets of the Company and the Restricted Subsidiaries as an
entirety to a Person in a transaction permitted under "--Merger, Consolidation
and Sale of Assets," the successor corporation shall be deemed to have sold the
properties and assets of the Company and the Restricted Subsidiaries not
transferred for purposes of this covenant and shall comply with the provisions
of this covenant with respect to such deemed sale as if it were an Asset Sale.
In addition, the fair market value (as determined in good faith by the Board of
Directors of the Company) of such properties and assets of the Company or the
Restricted Subsidiaries deemed to be sold shall be deemed to be Net Cash
Proceeds for purposes of this covenant.

    Each Net Proceeds Offer will be mailed to the record Holders as shown on the
register of Holders within 30 days following the Net Proceeds Offer Trigger
Date, with a copy to the Trustee, and shall comply with the procedures set forth
in the Indenture. Upon receiving notice of the Net Proceeds Offer, Holders may
elect to tender their exchange notes in whole or in part in integral multiples
of $1,000 in exchange for cash. To the extent Holders properly tender exchange
notes in an amount exceeding the Net Proceeds Offer Amount, exchange notes of
tendering Holders will be purchased on a pro rata basis based on the principal
amount of exchange notes (and other Indebtedness for which a concurrent offer is
being made as permitted by this covenant) tendered. A Net Proceeds Offer shall
remain open for a period of 20 business days or such longer period as may be
required by law.

    The Company will comply with the requirements of Rule 14e-l under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of exchange notes pursuant to a Net Proceeds Offer. To the extent
that the provisions of any securities laws or regulations conflict with the
"Asset Sale" provisions of the Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the "Asset Sale" provisions of the Indenture by
virtue thereof.

    LIMITATION ON DISTRIBUTIONS AND OTHER PAYMENT RESTRICTIONS AFFECTING
     SUBSIDIARIES

    The Company will not, and will not cause or permit any of the Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or permit to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to:

    (a) pay dividends or make any other distributions on or in respect of its
       Capital Stock;

    (b) make loans or advances or pay any Indebtedness or other obligation owed
       to the Company or any other Restricted Subsidiary; or

    (c) transfer any of its property or assets to the Company or any other
       Restricted Subsidiary, except for such encumbrances or restrictions
       existing under or by reasons of:

       (1) applicable law or regulation or NYSE regulations;

                                       78
<PAGE>
       (2) the Indenture;

       (3) customary non-assignment provisions of any contract or any lease
           governing a leasehold interest of any Restricted Subsidiary;

       (4) any instrument governing Acquired Indebtedness, which encumbrance or
           restriction is not applicable to any Person, or the properties or
           assets of any Person, other than the Person or the properties or
           assets of the Person so acquired;

       (5) agreements existing on the Issue Date to the extent and in the manner
           such agreements are in effect on the Issue Date;

       (6) any other agreement entered into after the Issue Date that contains
           encumbrances and restrictions that are not materially more
           restrictive with respect to any Restricted Subsidiary than those in
           effect with respect to such Restricted Subsidiary pursuant to
           agreements as in effect on the Issue Date so long as any such
           restrictions expressly permit scheduled payments on the exchange
           notes;

       (7) customary restrictions on the transfer of any property or assets
           arising under a security agreement governing a Lien permitted under
           the Indenture; and

       (8) any agreement governing Refinancing Indebtedness incurred to
           Refinance the Indebtedness issued, assumed or incurred pursuant to an
           agreement referred to in clause (2), (4) or (5) above; provided,
           however, that the provisions relating to such encumbrance or
           restriction contained in any such Refinancing Indebtedness are not
           materially more restrictive than the provisions relating to such
           encumbrance or restriction contained in agreements referred to in
           such clause (2), (4) or (5) and expressly permit dividends and other
           distributions for scheduled payments on the exchange notes.

    LIMITATION ON ISSUANCE AND SALE OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES

    The Company will not permit:

    (a) any Restricted Subsidiary to issue any Capital Stock other than to the
       Company or a Restricted Subsidiary;

    (b) any Person (other than the Company or a Restricted Subsidiary) to own or
       control any Capital Stock of any Restricted Subsidiary (other than
       directors' qualifying shares or as may be required by law);

    PROVIDED, that clauses (a) and (b) will not prohibit:

       (1) any sale of 100% of the shares of the Capital Stock of any Restricted
           Subsidiary owned by the Company or any Restricted Subsidiary effected
           in accordance with "--Limitation on the Sale of Assets," or

       (2) any sale of 100% of the shares of the Capital Stock of any Restricted
           Subsidiary owned by the Company or any Restricted Subsidiary effected
           in accordance with "--Merger, Consolidation and Sale of Assets."

    LIMITATION ON LIENS

    The Company will not, and will not cause or permit any of the Restricted
Subsidiaries to, directly or indirectly, create, incur, assume or permit or
suffer to exist any Liens of any kind against or upon, or enter into or
otherwise become liable in respect of, a Sale and Leaseback Transaction with
respect to, any property or assets of the Company or any of the Restricted
Subsidiaries, whether owned on the

                                       79
<PAGE>
Issue Date or acquired after the Issue Date, or any proceeds therefrom or assign
or otherwise convey any right to receive income or profit therefrom unless:

    (1) in the case of Liens securing Indebtedness that is expressly subordinate
       or junior in right of payment to the exchange notes, the exchange notes
       are secured by a Lien on such property, assets or proceeds that is senior
       in priority to such Liens; and

    (2) in all other cases, the exchange notes are equally and ratably secured,

    except for:

       (a) Liens existing as of the Issue Date to the extent and in the manner
           such Liens are in effect on the Issue Date;

       (b) Liens on Investment Securities securing Indebtedness incurred
           pursuant to clause (b) of the definition of "Permitted Indebtedness"
           and Interest Swap Obligations and Currency Agreements related

       (c) Liens on Capital Stock of Subsidiaries securing a bank credit
           facility of the Company and Interest Swap Obligations and Currency
           Agreements related thereto;

       (d) Liens securing Purchase Money Indebtedness (or Refinancing
           Indebtedness in respect thereof) or Sale and Leaseback Transactions
           involving Capitalized Lease Obligations, in each case Incurred
           pursuant to clause (1) of the definition of "Permitted Indebtedness;"
           provided, however, that:

           (1) the Purchase Money Indebtedness (or Refinancing Indebtedness) or
               Capitalized Lease Obligation shall not exceed the cost of the
               property or assets to be acquired or which is the subject of the
               Sale and Leaseback Transaction, and shall not be secured by any
               property or assets of the Company or any Restricted Subsidiary
               other than the property and assets to be acquired or which is the
               subject of the Sale and Leaseback Transaction, and

           (2) the Lien securing any Purchase Money Indebtedness shall be
               created within 90 days of such acquisition;

       (e) Liens securing Acquired Indebtedness (and any Refinancing
           Indebtedness in respect thereof); provided that:

           (1) the Liens secured the Acquired Indebtedness at the time of and
               prior to the Incurrence of the Acquired Indebtedness by the
               Company or a Restricted Subsidiary and were not granted in
               connection with, or in anticipation of the Incurrence of the
               Acquired Indebtedness by the Company or a Restricted Subsidiary;
               and

           (2) the Liens do not extend to or cover any property or assets of the
               Company or of any of the Restricted Subsidiaries other than the
               property or assets that secured the Acquired Indebtedness prior
               to the time the Indebtedness became Acquired Indebtedness of the
               Company or a Restricted Subsidiary;

       (f) Liens securing the exchange notes;

       (g) Liens in favor of the Company;

           Indebtedness, which Refinanced Indebtedness had been secured by a
           Lien permitted under the Indenture; provided, however, that such
           Liens do not extend to or cover any property or assets of the Company
           or any of the Restricted Subsidiaries not securing the Indebtedness
           so Refinanced; and

    MERGER, CONSOLIDATION AND SALE OF ASSETS

    The Company will not, in a single transaction or series of related
transactions, consolidate or merge with or into any Person, or sell, assign,
transfer, lease, convey or otherwise dispose of (or cause or permit any
Restricted Subsidiary to sell, assign, transfer, lease, convey or otherwise
dispose of) all or substantially all of the Company's assets (determined on a
consolidated basis for the Company and the Restricted Subsidiaries) whether as
an entirety or substantially as an entirety to any Person unless:

    (1) either:

       (a) the Company shall be the surviving or continuing corporation; or

       (b) the Person (if other than the Company) formed by such consolidation
           or into which the Company is merged or the Person which acquires by
           sale, assignment, transfer, lease, conveyance or other disposition
           the properties and assets of the Company and the Restricted
           Subsidiaries substantially as an entirety (the "Surviving Entity"):

           (x) shall be a corporation organized and validly existing under the
               laws of the United States or any State thereof or the District of
               Columbia; and

           (y) shall expressly assume, by supplemental indenture (in form and
               substance reasonably satisfactory to the Trustee), executed and
               delivered to the Trustee, the due and punctual payment of the
               principal of, and premium, if any, and interest on all of the
               exchange notes and the performance of every covenant of the
               exchange notes, the Indenture and the Registration Rights
               Agreement on the part of the Company to be performed or observed;

    (2) immediately after giving effect to such transaction and the assumption
       contemplated by clause (1)(b)(y) above (including giving effect to any
       Indebtedness and Acquired Indebtedness Incurred or anticipated to be
       Incurred in connection with or in respect of such transaction), the
       Company or such Surviving Entity, as the case may be, shall be able to
       incur at least $1.00 of additional Indebtedness (other than Permitted
       Indebtedness) pursuant to the covenant described under "--Limitation on
       Incurrence of Additional Indebtedness";

    (3) immediately before and immediately after giving effect to such
       transaction and the assumption contemplated by clause (1)(b)(y) above
       (including, without limitation, giving effect to any Indebtedness and
       Acquired Indebtedness incurred or anticipated to be incurred and any Lien
       granted in connection with or in respect of the transaction), no Default
       or Event of Default shall have occurred or be continuing; and

    (4) the Company or the Surviving Entity shall have delivered to the Trustee
       an officers' certificate and an opinion of counsel, each stating that
       such consolidation, merger, sale, assignment, transfer, lease, conveyance
       or other disposition and, if a supplemental indenture is required in
       connection with such transaction, such supplemental indenture comply with
       the applicable provisions of the Indenture and that all conditions
       precedent in the Indenture relating to such transaction have been
       satisfied.

    The above paragraph will not apply to a merger or consolidation between the
Company and a Restricted Subsidiary in which the Company is the surviving
company or between one or more Restricted Subsidiaries to the extent that a
Person that is a Restricted Subsidiary immediately before and after the
transaction is the surviving entity, or to the sale of substantially all of the
assets of a Restricted Subsidiary to the Company or to a Person that is a
Restricted Subsidiary immediately before and after the transaction. For purposes
of this covenant, the transfer by lease, assignment, sale or otherwise, in a
single transaction or series of transactions, of all or substantially all of the
properties or assets of one or more Restricted Subsidiaries, the Capital Stock
of which constitutes all or substantially

                                       81
<PAGE>
all of the properties and assets of the Company, shall be deemed to be the
transfer of all or substantially all of the properties and assets of the
Company.

    The Indenture provides that upon any consolidation, combination or merger or
any transfer of all or substantially all of the assets of the Company in
accordance with the foregoing, in which the Company is not the continuing
corporation, the successor Person formed by such consolidation or into which the
Company is merged, or to which such conveyance, lease or transfer is made, shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under the Indenture and the exchange notes with the same effect as
if such surviving entity had been named as such.

    LIMITATIONS ON TRANSACTIONS WITH AFFILIATES

    (a) The Company will not, and will not permit any of the Restricted
       Subsidiaries to, directly or indirectly, enter into or permit to exist
       any transaction or series of related transactions (including, without
       limitation, the purchase, sale, lease or exchange of any property or the
       rendering of any service) with, or for the benefit of, any of its
       Affiliates (each an "Affiliate Transaction") unless the Affiliate
       Transaction is on terms that are not materially less favorable than those
       that would have reasonably been expected in a comparable transaction at
       such time on an arm's-length basis from a Person that is not an Affiliate
       of the Company or such Restricted Subsidiary. Prior to the consummation
       by the Company or any Restricted Subsidiary of any Affiliate Transactions
       (or series of related Affiliate Transactions which are similar or part of
       a common plan) involving aggregate payments or other property with a fair
       market value in excess of:

       (1) $5 million, the Company or such Restricted Subsidiary, as the case
           may be, shall obtain the approval of its Board of Directors
           (including a majority of the independent directors) of such
           transaction or series of related transactions evidenced by a Board
           Resolution stating that such Board of Directors (including a majority
           of the independent directors) has determined that such transaction
           complies with the foregoing provisions, and

       (2) $10 million, the Company or such Restricted Subsidiary, as the case
           may be, shall obtain a favorable opinion as to the fairness of such
           transaction or series of related transactions to the Company or the
           relevant Restricted Subsidiary, as the case may be, from a financial
           point of view, from an Independent Financial Advisor, and file it
           with the Trustee.

    (b) The restrictions set forth in paragraph (a) above shall not apply to:

       (1) employment, stock option, consulting, agency or other compensation or
           benefit plans, arrangements and agreements of the Company or any
           Restricted Subsidiary in accordance with the Annual Incentive Plan or
           the Equity Incentive Plan or as approved by a majority of the
           disinterested members of the Board of Directors (or a majority of the
           disinterested members of a committee thereof);

       (2) reasonable fees and compensation paid to directors, and reasonable
           indemnity provided on behalf of officers, directors, employees,
           consultants or agents, of the Company or any Restricted Subsidiary as
           determined in good faith by the Company's Board of Directors or
           senior management;

       (3) transactions exclusively between or among the Company and any
           Restricted Subsidiaries or exclusively between or among Restricted
           Subsidiaries, provided such transactions are not otherwise prohibited
           by the Indenture; and

       (4) Restricted Payments permitted to be made pursuant to the
           "--Limitation on Restricted Payments" covenant.

    LIMITATION ON DESIGNATIONS OF UNRESTRICTED SUBSIDIARIES

    The Company may designate any Subsidiary of the Company, other than
LaBranche or a Person holding Capital Stock of LaBranche, as an "Unrestricted
Subsidiary" under the Indenture (a "Designation") only if:

    (a) no Default shall have occurred and be continuing at the time of or after
       giving effect to such Designation; and

    (b) the Company would be permitted under the Indenture to make an Investment
       at the time of Designation assuming the effectiveness of the Designation
       in an amount (the "Designation Amount") equal to the sum of:

       (1) the fair market value of the Capital Stock of the Subsidiary owned by
           the Company and/or any of the Restricted Subsidiaries on such date
           and

       (2) the aggregate amount of Indebtedness of the Subsidiary owed to the
           Company and the Restricted Subsidiaries on that date; and

    (c) the Company would be permitted to incur $1.00 of additional Indebtedness
       (other than Permitted Indebtedness) pursuant to the covenant described
       under "--Limitation on Incurrence of Additional Indebtedness" at the time
       of Designation assuming the effectiveness of the Designation.

    In the event of any such Designation, the Company shall be deemed to have
made an Investment constituting a Restricted Payment in the Designation Amount
pursuant to the covenant described under "--Limitation on Restricted Payments"
for all purposes of the Indenture. The Indenture will further provide that the
Company shall not, and shall not permit any Restricted Subsidiary to, at any
time:

       (1) provide direct or indirect credit support for or a guarantee of any
           Indebtedness of any Unrestricted Subsidiary (including any
           undertaking, agreement or instrument evidencing such Indebtedness),

       (2) be directly or indirectly liable for any Indebtedness of any
           Unrestricted Subsidiary or,

       (3) be directly or indirectly liable for any Indebtedness that provides
           that the holder thereof may (upon notice, lapse of time or both)
           declare a default thereon or cause the payment thereof to be
           accelerated or payable prior to its final scheduled maturity upon the
           occurrence of a default with respect to any Indebtedness of any
           Unrestricted Subsidiary (including any right to take enforcement
           action against the Unrestricted Subsidiary).

    The Company may revoke any Designation of a Subsidiary as an Unrestricted
Subsidiary ("Revocation"), whereupon such Subsidiary shall then constitute a
Restricted Subsidiary, if:

    (a) no Default shall have occurred and be continuing at the time and after
       giving effect to such Revocation; and

    (b) all Liens and Indebtedness of such Unrestricted Subsidiaries outstanding
       immediately following such Revocation would, if incurred at such time,
       have been permitted to be incurred for all purposes of the Indenture.

    All Designations and Revocations must be evidenced by an officers'
certificate of the Company delivered to the Trustee certifying compliance with
the foregoing provisions.

    REPORTS TO HOLDERS

    The Indenture provides that the Company will deliver to the Trustee within
15 days after the filing of the same with the Commission, copies of the
quarterly and annual reports and of the information,

                                       83
<PAGE>
documents and other reports, if any, that the Company is required to file with
the Commission pursuant to Section 13 or 15(d) of the Exchange Act. The
Indenture further provides that, notwithstanding that the Company may not be
subject to the reporting requirements of Sections 13 or 15(d) of the Exchange
Act, the Company will file with the Commission, to the extent permitted, and
provide the Trustee and Holders with such annual and quarterly reports and such
information, document and other reports specified in Section 13 and 15(d) of the
Exchange Act. The Company will also comply with the other provisions of TIA
Section314(a).

EVENTS OF DEFAULT

    The following events are defined in the Indenture as "Events of Default":

    (a) the failure to pay interest (including any additional interest payable,
       under the Registration Rights Agreement) on any exchange notes when the
       same becomes due and payable and the default continues for a period of 30
       days;

    (b) the failure to pay the principal on any exchange notes, when such
       principal becomes due and payable, at maturity, upon redemption or
       otherwise (including the failure to make a payment to purchase exchange
       notes tendered pursuant to a Change of Control Offer or a Net Proceeds
       Offer), whether or not such payment shall be prohibited by the
       subordination provision of the Indenture;

    (c) a default in the observance or performance of the covenant described
       under "--Certain Covenants--Merger, Consolidation and Sale of Assets";

    (d) a default in the observance or performance of any other covenant or
       agreement contained in the Indenture, which default continues for a
       period of 45 days after the Company receives written notice specifying
       the default from the Trustee or the Holders of at least 25% of the
       outstanding principal amount of the exchange notes;

    (e) a default under any mortgage, indenture or instrument under which there
       may be issued or by which there may be secured or evidenced any
       Indebtedness of the Company or of any Restricted Subsidiary (or the
       payment of which is guaranteed by the Company or any Restricted
       Subsidiary), whether such Indebtedness now exists or is created after the
       Issue Date, which default:

       (1) is caused by failure to pay principal of such Indebtedness after any
           applicable grace period provided in such Indebtedness on the date of
           such default (a "payment default") or

       (2) results in the acceleration of such Indebtedness prior to its express
           maturity,

    and the aggregate principal amount of any Indebtedness to which clause (1)
    or (2) applies at the relevant time, exceeds $5.0 million;

    (f) one or more judgments in an aggregate amount in excess of $5.0 million
       shall have been rendered against the Company or any of the Restricted
       Subsidiaries and such judgments remain undischarged, unpaid or unstayed
       for a period of 45 days after such judgment or judgments become final and
       nonappealable;

    (g) certain events of bankruptcy affecting the Company or any of the
       Significant Subsidiaries (or any group of Subsidiaries which, taken
       together, would constitute a Significant Subsidiary) pursuant to SIPA or
       bankruptcy laws;

    (h) LaBranche is not a specialist broker in good standing with the NYSE;

                                       84
<PAGE>
    (i) the Commission revokes the registration of LaBranche as a broker-dealer
       under the Exchange Act or LaBranche fails to maintain such registration;
       or

    (j) the Examining Authority (as defined in Rule 15c3-1) for the Company
       shall suspend (and not reinstate within 10 days) or revoke LaBranche's
       status as a member organization thereof.

    If an Event of Default (other than an Event of Default specified in clause
(g) above) shall occur and be continuing, the Trustee or the Holders of at least
25% in principal amount of outstanding exchange notes may declare the principal
of, and accrued interest on, all the exchange notes to be due and payable by
notice in writing to the Company and (if given by the Holders) the Trustee
specifying the respective Events of Default and that it is a "notice of
acceleration," and the same shall become immediately due and payable. If an
Event of Default specified in clause (g) above occurs and is continuing, then
all unpaid principal of, and accrued and unpaid interest on, all of the
outstanding exchange notes shall become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holder.

    The Indenture provides that, at any time after a declaration of acceleration
with respect to the exchange notes as described in the preceding paragraph, the
Holders of a majority in principal amount of the then outstanding exchange notes
may rescind and cancel such declaration and its consequences:

       (1) if the rescission would not conflict with any judgment or decree;

       (2) if all existing Events of Default have been cured or waived except
           nonpayment of principal or interest that has become due solely
           because of the acceleration;

       (3) to the extent payment of such interest is lawful, if interest on
           overdue installments of interest and overdue principal, which has
           become due otherwise than by such declaration of acceleration, has
           been paid;

       (4) if the Company has paid the Trustee its reasonable compensation and
           reimbursed the Trustee for its expenses, disbursements and advances;
           and

       (5) in the event of the cure or waiver of an Event of Default of the type
           described in clause (g) of the description above of Events of
           Default, the Trustee shall have received an officers' certificate and
           an opinion of counsel that such Event of Default has been cured or
           waived.

    No such rescission shall affect any subsequent Default or impair any right
consequent thereto.

    The Holders of a majority in principal amount of the then outstanding
exchange notes may waive any existing Default or Event of Default under the
Indenture, and its consequences, except a default in the payment of the
principal of or interest on any exchange notes.

    Holders of the exchange notes may not enforce the Indenture or the exchange
notes except as provided in the Indenture and under the TIA. Subject to the
provisions of the Indenture relating to the duties of the Trustee, the Trustee
is under no obligation to exercise any of its rights or powers under the
Indenture at the request, order or direction of any of the Holders, unless such
Holders have offered to the Trustee reasonable indemnity. Subject to all
provisions of the Indenture and applicable law, the Holders of a majority in
aggregate principal amount of the then outstanding exchange notes have the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee.

    The Company is required to provide an officers' certificate to the Trustee
promptly upon the Company obtaining knowledge of any Default or Event of Default
(provided that the Company shall provide such certification at least annually
whether or not it knows of any Default or Event of Default) that has occurred
and, if applicable, describe such Default or Event of Default and the status
thereof.

                                       85
<PAGE>
LEGAL DEFEASANCE AND COVENANT DEFEASANCE

    The Company may, at its option and at any time, elect to have its
obligations discharged with respect to the outstanding exchange notes ("Legal
Defeasance"). Such Legal Defeasance means that the Company shall be deemed to
have paid and discharged the entire indebtedness represented by the outstanding
exchange notes, except for:

    (1) the rights of Holders to receive payments in respect of the principal
       of, premium, if any, and interest on the exchange notes when such
       payments are due solely from the trust described below;

    (2) the Company's obligations with respect to the exchange notes concerning
       issuing temporary exchange notes, mutilated, destroyed, lost or stolen
       exchange notes and the maintenance of an office or agency for payments;

    (3) the rights, powers, trust, duties and immunities of the Trustee and the
       Company's obligations in connection therewith; and

    (4) the Legal Defeasance provisions of the Indenture.

    In addition, the Company may, at its option and at any time, elect to have
the obligations of the Company released with respect to certain covenants that
are described in the Indenture ("Covenant Defeasance") and thereafter any
omission or failure to comply with such obligations shall not constitute a
Default or Event of Default with respect to the exchange notes. In the event
Covenant Defeasance occurs, certain events (not including non-payment,
bankruptcy, receivership, reorganization and insolvency events) described under
"--Events of Default" will no longer constitute an Event of Default with respect
to the exchange notes.

    In order to exercise Legal Defeasance or Covenant Defeasance:

    (a) the Company must irrevocably deposit with the Trustee, in trust, for the
       benefit of the Holders cash in U.S. dollars, non-callable U.S. government
       obligations, or a combination thereof, in such amounts as will be
       sufficient, in the opinion of a nationally recognized firm of independent
       public accounts, to pay the principal of, premium, if any, and interest
       on the exchange notes on the stated date of payment thereof or on the
       applicable redemption date, as the case may be;

    (b) in the case of Legal Defeasance, the Company shall have delivered to the
       Trustee an opinion of counsel in the United Stares reasonably acceptable
       to the Trustee confirming that:

       (1) the Company has received from, or there has been published by, the
           Internal Revenue Service a ruling; or

       (2) since the date of the Indenture, there has been a change in the
           applicable federal income tax law, in either case to the effect that,
           and based thereon such opinion of counsel shall confirm that, the
           Holders will not recognize income, gain or loss for federal income
           tax purposes as a result of such Legal Defeasance and will be subject
           to federal income tax on the same amounts, in the same manner and at
           the same times as would have been the case if such Legal Defeasance
           had not occurred;

    (c) in the case of Covenant Defeasance, the Company shall have delivered to
       the Trustee an opinion of counsel in the United States reasonably
       acceptable to the Trustee confirming that the Holders will not recognize
       income, gain or loss for federal income tax purposes as a result of such
       Covenant Defeasance and will be subject to federal income tax on the same
       amounts, in the same manner and at the same times as would have been the
       case if such Covenant Defeasance had not occurred;

    (d) no Default or Event of Default shall have occurred and be continuing on
       the date of such deposit or insofar as Events of Default from bankruptcy
       or insolvency events are concerned, at any time in the period ending on
       the 91st day after the date of deposit;

                                       86
<PAGE>
    (e) such Legal Defeasance or Covenant Defeasance shall not result in a
       breach or violation of, or constitute a default under any material
       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 is bound;

    (f) the Company shall have delivered to the Trustee an officers' certificate
       stating that the deposit was not made by the Company with the intent of
       preferring the Holders over any other creditors of the Company or with
       the intent of defeating, hindering, delaying or defrauding other
       creditors of the Company or others;

    (g) the Company shall have delivered to the Trustee an officers' certificate
       and an opinion of counsel, each stating that all conditions precedent
       provided for or relating to the Legal Defeasance or the Covenant
       Defeasance have been complied with;

    (h) the Company shall have delivered to the Trustee an opinion of counsel to
       the effect that after the 91st day following the deposit, the trust funds
       will not be subject to the effect of any applicable bankruptcy,
       insolvency, reorganization or similar laws affecting creditors' rights
       generally; and

    (i) certain other customary conditions precedent are satisfied.

SATISFACTION AND DISCHARGE

    The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights as expressly provided for in the Indenture) as to
all outstanding exchange notes when:

    (a) either:

       (1) all the exchange notes theretofor authenticated and delivered (except
           lost, stolen or destroyed exchange notes which have been replaced or
           paid and exchange notes for whose payment money has theretofor been
           deposited in trust or segregated and held in trust by the Company and
           thereafter repaid to the Company or discharged from such trust) have
           been delivered to the Trustee for cancellation; or

       (2) all exchange notes not theretofor delivered to the Trustee for
           cancellation have become due and payable and the Company has
           irrevocably deposited or caused to be deposited with the Trustee
           funds in an amount sufficient to pay and discharge the entire
           Indebtedness on the exchange notes not theretofor delivered to the
           Trustee for cancellation, for principal of, and premium, if any, and
           interest on, the exchange notes to the date of deposit together with
           irrevocable instructions from the Company directing the Trustee to
           apply such funds to the payment thereof at maturity or redemption, as
           the case may be;

    (b) the Company has paid all other sums payable under the Indenture by the
       Company; and

    (c) the Company has delivered to the Trustee an officers' certificate and an
       opinion of counsel stating that all conditions precedent under the
       Indenture relating to the satisfaction and discharge of the Indenture
       have been complied with.

MODIFICATION OF THE INDENTURE

    From time to time, the Company and the Trustee, without the consent of the
Holders, may amend the Indenture for certain specified purposes, including
curing ambiguities, doubts or inconsistencies, so long as such change does not,
in the opinion of the Trustee, adversely affect the rights of any of the Holders
in any material respect. In formulating its opinion on such matters, the Trustee
will be entitled to rely on such evidence as it deems appropriate, including,
without limitation, solely on an opinion of counsel. Other modifications and
amendments of the Indenture may be made with the consent of the

                                       87
<PAGE>
Holders of a majority in principal amount of the then outstanding exchange notes
issued under the Indenture, except that, without the consent of each Holder
affected thereby, no amendment may:

    (a) reduce the amount of exchange notes whose holders must consent to an
       amendment;

    (b) reduce the rate of or change or have the effect of changing the time for
       payment of interest, including defaulted interest, on any exchange notes;

    (c) reduce the principal of or change or have the effect of changing the
       fixed maturity of any exchange notes, or change the date on which any
       exchange notes may be subject to redemption or repurchase, or reduce the
       redemption or repurchase price therefor;

    (d) make any exchange notes payable in money other than that stated in the
       exchange notes;

    (e) make any change in provisions of the Indenture protecting the right of
       each Holder to receive payment of principal of and interest on such
       exchange notes on or after the stated due date thereof or to bring suit
       to enforce such payment, or permitting Holders of a majority in principal
       amount of the then outstanding exchange notes to waive Defaults or Events
       of Default;

    (f) amend, change or modify in any material respect the obligation of the
       Company to make and consummate a Change of Control Offer after the
       occurrence of a Change of Control or make and consummate a Net Proceeds
       Offer with respect to any Asset Sale that has been consummated or modify
       any of the provisions or definitions with respect thereto; or

    (g) modify or change any provision of the Indenture or the related
       definitions affecting the ranking of the exchange notes in a manner which
       adversely affects the Holders.

GOVERNING LAW

    The Indenture provides that it and the exchange notes will be governed by,
and construed in accordance with, the laws of the State of New York but without
giving effect to applicable principles of conflicts of law to the extent that
the application of the law of another jurisdiction would be required thereby.

THE TRUSTEE

    The Indenture provides that, except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set forth
in the Indenture. During the existence of an Event of Default, the Trustee will
exercise such rights and power vested in it by the Indenture, and use the same
degree of care and skill in its exercise as a prudent man would exercise or use
under the circumstances in the conduct of his own affairs.

    The Indenture and the provisions of the TIA contain certain limitations on
the rights of the Trustee, should it become a creditor of the Company, to obtain
payments of claims in certain cases or to realize on certain property received
in respect of any such claim as security or otherwise. Subject to the TIA, the
Trustee will be permitted to engage in other transactions; provided that if the
Trustee acquires any conflicting interest as described in the TIA, it must
eliminate such conflict or resign.

NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS OR
  EMPLOYEES

    The Indenture provides that no recourse for the payment of the principal of,
premium, if any, or interest on any of the exchange notes or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Indenture, or in any of
the exchange notes or because of the creation of any Indebtedness represented
thereby shall be had against any Person solely as a result of their capacity as
incorporator, stockholder, officer, director, employee or controlling person of
the Company or of any successor Person thereof. Each holder, by accepting the
exchange notes, waives and releases all such liability.

                                       88

BOOK-ENTRY, DELIVERY AND FORM

    The exchange notes will be issued in the form of a global note (the "Global
Note"). The Global Note will be deposited with, or on behalf of, The Depository
Trust Company ("DTC") and registered in the name of DTC or its nominee. Except
as set forth below, the Global Note may be transferred in whole and not in part,
only to DTC or another nominee of DTC. Investors may hold their beneficial
interests in the Global Note directly through DTC if they have an account with
DTC or indirectly through Euroclear System ("Euroclear") or Cedel Bank, N.A.
("Cedel Bank"), organizations which have accounts with DTC.

    Exchange notes that are issued as described below under "--Certificated
Exchange Notes" will be issued in definitive form. Upon the transfer of an
exchange note in definitive form, such exchange note will, unless the Global
Note has previously been exchanged for exchange notes in definitive form, be
exchanged for an interest in the Global Note representing the principal amount
of exchange notes being transferred.

CERTAIN BOOK-ENTRY PROCEDURES FOR THE GLOBAL NOTE

    The descriptions of the operations and procedures of DTC, Euroclear and
Cedel Bank set forth below are provided solely as a matter of convenience. These
operations and procedures are solely within the control of the respective
settlement systems and are subject to change by them from time to time. The
Company takes no responsibility for these operations or procedures, and
investors are urged to contact the relevant system or its participants directly
to discuss these matters.

    DTC has advised the Company that it is:

    - a limited purpose trust company organized under the laws of the State of
      New York,

    - a "banking organization" within the meaning of the New York Banking Law,

    - a member of the Federal Reserve System,

                                      104
<PAGE>
    - a "clearing corporation" within the meaning of the Uniform Commercial
      Code, as amended and

    - a "clearing agency" registered pursuant to Section 17A of the Exchange
      Act.

    DTC was created to hold securities for its participants (collectively, the
"Participants") and facilitates the clearance and settlement of securities
transactions between Participants through electronic book-entry changes to the
accounts of Participants, thereby eliminating the need for physical transfer and
delivery of certificates. DTC Participants include securities brokers and
dealers (including the initial purchasers), banks and trust companies, clearing
corporations and certain other organizations. Indirect access to DTC's system is
also available to other entities such as banks, brokers, dealers and trust
companies (collectively, the "Indirect Participants") that clear through or
maintain a custodial relationship with a Participant, either directly or
indirectly. Investors who are not Participants may beneficially own securities
held by or on behalf of DTC only through Participants or Indirect Participants.

    The Company expects that pursuant to procedures established by DTC

    - upon deposit of the Global Note, DTC will credit the accounts of
      Participants with an interest in the Global Note, and

    - ownership of the exchange notes will be shown on, and the transfer of
      ownership thereof will be effected only through, records maintained by DTC
      (with respect to the interests of Participants) and the records of
      Participants and the Indirect Participants (with respect to the interests
      of persons other than Participants).

    The laws of some jurisdictions may require that certain purchasers of
securities take physical delivery of such securities in definitive form.
Accordingly, the ability to transfer interests in the exchange notes represented
by a Global Note to such persons may be limited. In addition, because DTC can
act only on behalf of its Participants, who in turn act on behalf of persons who
hold interests through Participants, the ability of a person having an interest
in exchange notes represented by a Global Note to pledge or transfer such
interest to persons or entities that do not participate in DTC's system, or to
otherwise take actions in respect of such interest, may be affected by the lack
of a physical definitive security in respect of such interest.

    So long as DTC or its nominee is the registered owner of the Global Note,
DTC or such nominee, as the case may be, will be considered the sole owner or
holder of the exchange notes resented by the Global Note for all purposes under
the Indenture. Except as provided below, owners of beneficial interests in the
Global Note will not be entitled to have exchange notes represented by such
Global Note registered in their names, will not receive or be entitled to
receive physical delivery of certificated notes, and will not be considered the
owners or holders thereof under the Indenture for any purpose, including with
respect to the giving of any direction, instruction or approval to the Trustee
thereunder. Accordingly, each holder owning a beneficial interest in the Global
Note must rely on the procedures of DTC and, if such holder is not a Participant
or an Indirect Participant, on the procedures of the Participant through which
such holder owns its interest, to exercise any rights of a holder of exchange
notes under the Indenture of such Global Note. The Company understands that
under existing industry practice, in the event that the Company requests any
action of holders of exchange notes, or a holder that is an owner of a
beneficial interest in the Global Note desires to take any action that DTC, as
the holder of such Global Note, is entitled to take, DTC could authorize the
Participants to take such action and the Participants would authorize holders
owning through such Participants to take such action or would otherwise act upon
the instruction of such holders. Neither the Company nor the Trustee will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of exchange notes by DTC, or for maintaining,
supervising or reviewing any records of DTC relating to such exchange notes.

                                      105
<PAGE>
    The Company expects that DTC or its nominee, upon receipt of any payment of
principal or interest on the Global Note, will credit Participants' accounts
with payments in amounts proportionate to their respective beneficial interests
in the principal amount of the Global Note as shown on the records of DTC or its
nominee. The Company also expects that payments by Participants to owners of
beneficial interests in the Global Note held through such Participants will be
governed by standing instructions and customary practices and will be the
responsibility of such Participants. The Company will not have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of, beneficial ownership interests in the Global Note
for any exchange note or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests or for any other aspect of the
relationship between DTC and Participants or the relationship between such
Participants and the owners of beneficial interests in the Global Note owning
through such Participants.

    Transfers between Participants will be effected in accordance with DTC's
procedures, and will be settled in same-day funds. Transfers between
participants in Euroclear or Cedel Bank will be effected in the ordinary way in
accordance with their respective rules and operating procedures.

    Cross-market transfers between Participants, on the one hand, and Euroclear
or Cedel Bank participants, on the other hand, will be effected through DTC in
accordance with DTC's rules on behalf of Euroclear or Cedel Bank, as the case
may be, by its respective depositary; however, such cross-market transactions
will require delivery of instructions to Euroclear or Cedel Bank, as the case
may be, by the counterparty in such system in accordance with the rules and
procedures and within the established deadlines (Brussels time) of such system.
Euroclear or Cedel Bank, as the case may be, will, if the transaction meets its
settlement requirements, deliver instructions to its respective depositary to
take action to effect final settlement on its behalf by delivering or receiving
interests in the relevant Global Notes in DTC, and making or receiving payment
in accordance with normal procedures for same-day funds settlement applicable to
DTC. Euroclear participants and Cedel Bank participants may not deliver
instructions directly to the depositaries for Euroclear or Cedel Bank.

    Because of time zone differences, the securities account of a Euroclear or
Cedel Bank participant purchasing an interest in a Global Note from a
Participant will be credited, and any such crediting will be reported to the
relevant Euroclear or Cedel Bank participant, during the securities settlement
processing day (which must be a business day for Euroclear and Cedel Bank)
immediately following the settlement date of DTC. Cash received in Euroclear or
Cedel Bank as a result of sales of interests in the Global Note by or through a
Euroclear or Cedel Bank participant to a Participant will be received with value
on the settlement date of DTC but will be available in the relevant Euroclear or
Cedel Bank cash account only as of the business day for Euroclear or Cedel Bank
following DTC's settlement date.

    Although DTC, Euroclear and Cedel Bank have agreed to the foregoing
procedures to facilitate transfers of interests in the Global Note among
participants in DTC, Euroclear and Cedel Bank, they are under no obligation to
perform or to continue to perform such procedures, and such procedures may be
discontinued at any time. Neither the Company nor the Trustee will have any
responsibility for the performance by DTC, Euroclear or Cedel Bank or their
respective participants or indirect participants of their respective obligations
under the rules and procedures governing their operations.

CERTIFICATED EXCHANGE NOTES

    If:

    - DTC (1) notifies the Company that it is no longer willing or able to act
      as a depositary and the Company fails to appoint a successor depositary or
      (2) ceases to be registered as a clearing agency under the Exchange Act;

    - the Company, at its option, notifies the Trustee in writing that it elects
      to cause the issuance of exchange notes in certificated form; or

                                      106
<PAGE>
    - at the request of DTC, if there shall have occurred and be continuing an
      event of default with respect to the exchange notes,

    then, upon surrender by DTC of the Global Note, certificated exchange notes
    in definitive form in denominations of U.S. $1,000 and integral multiples
    thereof will be issued to each person that DTC identifies as the beneficial
    owner of the exchange notes represented by the Global Note. Upon any such
    issuance, the Trustee is required to register such certificated exchange
    notes in the name of such person or persons (or the nominee of any thereof)
    and cause the same to be delivered thereto. Subject to the foregoing, the
    Global Note is not exchangeable, except for a Global Note of the same
    aggregate denomination to be registered in the name of DTC or its nominee.

    Neither the Company nor the Trustee shall be liable for any delay by DTC or
any Participant or Indirect Participant in identifying the beneficial owners of
the related exchange notes and each such person may conclusively rely on, and
shall be protected in relying on, instructions from DTC for all purposes,
including with respect to the registration and delivery, and the respective
principal amounts, of the exchange notes to be issued.

REGISTRATION RIGHTS; LIQUIDATED DAMAGES

    We entered into a registration rights agreement with the initial purchasers
concurrently with the issuance of the initial notes. You may obtain a copy of
the agreement by calling or writing to us at One Exchange Plaza, New York, New
York 10006; (212) 425-1144. Under the agreement, we agreed to file with the SEC
an exchange offer registration statement of which this prospectus is a part with
respect to an offer to exchange the initial notes for a new series of exchange
notes with terms substantially identical to the initial notes. We will also file
a shelf registration statement to cover resales of initial notes or exchange
notes by holders who provide us with certain information if:

    a) we are not permitted to effect the exchange offer because the exchange
offer is not permitted by applicable law or SEC policy;

    b) the exchange offer is not completed within 120 days of the Issue Date;

    c) any holder of any private exchange notes so requests in writing to us
within 30 days after the completion of the exchange offer; or

    d) in the case of any holder that participates in the exchange offer, such
holder does not receive exchange notes on the date of the exchange that may be
sold without restriction under state and federal securities laws (other than due
solely to the status of such holder as an affiliate of the Company within the
meaning of the Securities Act).

    We will use our best efforts to obtain effectiveness of the applicable
registration statement as promptly as possible.

    UNDER EXISTING INTERPRETATIONS OF THE STAFF OF THE DIVISION OF CORPORATION
FINANCE OF THE SEC, THE EXCHANGE NOTES WOULD IN GENERAL BE FREELY TRADABLE AFTER
THE COMPLETION OF THE EXCHANGE OFFER WITHOUT FURTHER COMPLIANCE WITH THE
REGISTRATION AND DELIVERY REQUIREMENTS OF THE SECURITIES ACT. HOWEVER, THE SEC
INDICATED THAT IT MAY REPEAL THESE INTERPRETATIONS. FURTHERMORE, THE SEC MAY
ADOPT CERTAIN PROPOSED RULE CHANGES UNDER THE SECURITIES ACT. IF THE
INTERPRETATIONS REFERRED TO ABOVE ARE REPEALED BEFORE THE EXCHANGE OFFER IS
COMPLETED SO THAT THE EXCHANGE OFFER WOULD NO LONGER BE PERMISSIBLE, THEN
HOLDERS OF THE INITIAL NOTES WILL NOT BE ABLE TO RECEIVE EXCHANGE NOTES PURSUANT
TO AN EXCHANGE OFFER. RATHER, THE INITIAL NOTES WILL ONLY BE REGISTERED IN
CONNECTION WITH RESALES BY THE HOLDERS. IN CONNECTION WITH SUCH RESALES, THE
HOLDERS WILL BE REQUIRED TO DELIVER A PROSPECTUS TO THE PURCHASERS AND WILL BE
SUBJECT TO CERTAIN OF THE CIVIL LIABILITY PROVISIONS UNDER THE SECURITIES ACT.

                                      107
<PAGE>
    Under the registration rights agreement we agreed to:

    - file the exchange offer registration statement with the SEC by the 45th
      day after the closing of our initial note offering;

    - use our best efforts to obtain effectiveness of the exchange offer
      registration statement by the 90th day after the closing for our initial
      note offering;

    - unless the exchange offer would not be permitted by applicable law or SEC
      policy, commence the exchange offer and use our best efforts to issue by
      the 120th day after the closing of our initial note offering exchange
      notes in exchange for all initial notes tendered in the exchange offer;

    - if obligated to file a shelf registration statement, use our best efforts
      to file such shelf registration statement with the SEC by the 45th day
      following the date of the occurrence of one of the events specified in the
      registration rights agreement which gives rise to our obligation to file a
      shelf registration statement; and

    - if obligated to file a shelf registration statement, use our best efforts
      to obtain effectiveness of such shelf registration statement by the 45th
      day after the initial shelf registration filing date.

    We agreed to pay additional interest if:

    - we fail to file the exchange offer registration statement by the 45th day
      after the closing of our initial note offering;

    - the exchange offer registration statement is not declared effective by the
      SEC by the 90th day after the closing of our initial note offering;

    - we fail to consummate the exchange offer by the 120th day after the
      closing of our initial note offering;

    - the exchange offer registration statement is declared effective but
      thereafter ceases to be effective or usable in connection with resales of
      exchange notes in accordance with and during the periods specified in the
      registration rights agreement;

    - we fail to file a shelf registration statement by the 45th day following
      the date of the occurrence of one of the events specified in the
      registration rights agreement which gives rise to our obligation to file a
      shelf registration statement;

    - the shelf registration statement is not declared effective by the SEC by
      the 45th day following the initial shelf registration filing date; or

    - the shelf registration statement is declared effective but thereafter
      ceases to be effective or usable in connection with resales of Transfer
      Restricted Securities (as defined below) in accordance with and during the
      periods specified in the registration rights agreement.

    Each event described above is a "Registration Default." The term "Transfer
Restricted Securities" means each initial note, or exchange note, until:

    - in the case of an initial note, the date on which such initial note has
      been exchanged by a person other than a broker-dealer for an exchange note
      in the exchange offer;

    - in the case of an exchange note received by a broker-dealer in the
      exchange offer in exchange for an initial note, the date on which the
      exchange note is sold to a purchaser who receives from the broker-dealer
      on or prior to the date of sale a copy of the exchange offer prospectus;

    - in the case of an initial note, the date on which the initial note has
      been effectively registered under the Securities Act and disposed of under
      the shelf registration statement; or

                                      108
<PAGE>
    - in the case of an initial note, the date on which the initial note is
      publicly sold under Rule 144 under the Act.

    If a Registration Default occurs, we will pay to each holder of initial
notes or exchange notes, as liquidated damages and not as a penalty, additional
interest equal to 0.25% per annum of the aggregate principal amount of the
initial notes or exchange notes held by such holder, during the 90-day period
immediately following the occurrence of the first Registration Default. The
amount of additional interest will increase by an additional 0.25% per annum at
the beginning of each subsequent 90-day period until all Registration Defaults
have been cured, up to a maximum aggregate amount of additional interest equal
to 1.00% per annum. All accrued additional interest with respect to initial
notes or exchange notes held in global form will be paid by wire transfer of
immediately available funds or by federal funds check. All accrued additional
interest with respect to initial notes or exchange notes held in certificated
form will be paid by wire transfer to the accounts specified by the relevant
holder or by mailing checks to their registered addresses if no such accounts
have been specified. Following the cure of all Registration Defaults, the
accrual of additional interest will cease.

    Holders of initial notes have made certain representations to us (as
described in the registration rights agreement) to participate in the exchange
offer. Holders of initial notes and/or exchange notes must also deliver
information required to be included in the shelf registration statement and
provide comments on the shelf registration statement within the time periods set
forth in the registration rights agreement in order to have their initial notes
and/or exchange notes included in the registration statement and receive
liquidated damages as described above.

                       DESCRIPTION OF OTHER INDEBTEDNESS

    The following summarizes the principal terms of the other indebtedness of
LaBranche & Co Inc., LaBranche & Co. and LaB Investing Co. L.L.C. Copies of the
material agreements relating to the other indebtedness have been filed with the
SEC and the description below is qualified in its entirety by reference to the
agreements. See "Where You Can Find Additional Information."

CREDIT AGREEMENT WITH THE BANK OF NEW YORK

    Effective as of June 23, 1999, the Credit Agreement between LaBranche & Co.
and The Bank of New York was extended for an additional one-year term, and
amended in order to increase the credit facility available thereunder from $75.0
million to $100.0 million. Borrowings under the Credit Agreement are secured by
a pledge of the investment securities of LaBranche & Co. identified in the
Credit Agreement. Loans under the Credit Agreement will bear interest at The
Bank of New York's broker loan rate. All loans under the Credit Agreement will
become due on June 23, 2000.

    The Credit Agreement contains covenants that require LaBranche & Co., among
other things, to

    - maintain net capital of not less than $75.0 million, and

    - maintain a net worth of not less than $100.0 million.

    The Credit Agreement also restricts LaBranche & Co.'s ability to incur
additional indebtedness, including guarantee liabilities, certain mortgages or
other encumbrances or the assets pledged under the Credit Agreement.

LABRANCHE & CO.'S PRIVATE PLACEMENT DEBT

    LaBranche & Co. has two series of outstanding unsecured senior subordinated
notes in the aggregate principal amounts of $20.0 million and $15.0 million,
respectively. These notes mature on September 15, 2002 and June 3, 2008,
respectively, and bear interest payable quarterly at respective annual rates of
8.17% and 7.69%.

    LaBranche & Co. may prepay, at a premium, all or any part of the senior
subordinated notes at any time, provided that the amount prepaid is not less
than 5% of the aggregate principal amount of the senior subordinated notes then
outstanding.

    Upon the occurrence of a change of control, LaBranche & Co. may, but is not
required to, make one irrevocable separate offer to each holder of the senior
subordinated notes to prepay all of the senior subordinated notes then held by
that holder. The occurrence of a change of control also constitutes an event of
acceleration under each of the series of senior subordinated notes.

    Among other things, the agreements relating to the senior subordinated notes
require that LaBranche & Co. comply with certain covenants including covenants
that

    - restrict the type of businesses in which it may engage;

    - require its net capital to be at least 150% of the net capital required by
      the NYSE or the SEC and its adjusted partners' capital to be at least
      $40.0 million; and

    - prohibit it from making restricted payments.

                                      110
<PAGE>
    A failure to make timely payments of principal and/or interest on the senior
subordinated notes or the occurrence of certain other events may result in a
default under, or an acceleration of, the senior subordinated notes. These
events include:

    - the Securities Investor Protection Corporation makes an application
      stating that the customers of LaBranche & Co. are in need of protection
      under the Securities Investor Protection Act, and the application is not
      dismissed within 30 days;

    - the SEC revokes the registration of LaBranche & Co. as a broker-dealer;

    - the NYSE suspends the status of LaBranche & Co. as a member organization;
      and

    - LaBranche & Co. fails to meet its net capital requirements.

CASH SUBORDINATED LOAN AGREEMENTS

    LaBranche & Co. is a party to a number of separate cash subordinated loan
agreements with current employees, former partners and family members or
affiliates of current and former partners of the firm. These cash subordinated
loan agreements represent junior subordinated debt of LaBranche & Co. The
current aggregate principal amount of such subordinated indebtedness is
approximately $16.2 million. This debt bears interest payable quarterly at an
annual rate of 10.0%. LaBranche & Co. has the option to prepay all or a portion
of this debt, subject to the approval of the NYSE and the application of
regulatory net capital requirements. The indebtedness represented by these cash
subordinated loan agreements generally matures one year from the date of
issuance, subject to automatic rollover for additional one-year terms, unless
notice is given by either party not to renew the term at least seven months
prior to the scheduled maturity date.

    As part of the reorganization of our firm from partnership to corporate
form, LaBranche & Co. repaid $5.0 million in satisfaction of one of these cash
subordinated loan agreements and incurred $350,000 of subordinated indebtedness
pursuant to a new cash subordinated loan agreement in connection with the
redemption of a limited partnership interest which bears interest at an annual
rate of 8.0%.

NOTE ISSUED TO MILL BRIDGE

    In connection with the reorganization of our firm from partnership to
corporate form, we acquired the limited partnership interest in LaBranche & Co.
held by Mill Bridge, Inc. for $90.0 million, of which $74.0 million was paid in
cash upon the consummation of our initial note offering and our common stock
offering and $16.0 million was satisfied by the issuance by us of a note which
is payable over three years. This $16.0 million obligation is a senior unsecured
obligation of LaBranche & Co Inc. and is payable as to $5.0 million on the first
anniversary of the completion of our initial note offering and our common stock
offering, $5.0 million on the second anniversary of the completion of our
initial note offering and our common stock offering and $6.0 million on the
third anniversary of the completion of our initial note offering and our common
stock offering, and bears interest at an annual rate of 9.5%. This obligation
ranks pari passu with the exchange notes.

RETIREMENT PLAN OBLIGATIONS

    Upon the completion of our initial note offering and our common stock
offering, LaBranche & Co. repaid approximately $1.1 million in indebtedness owed
to participants in LaBranche & Co.'s retirement plan, which amount has been
accrued in the historical consolidated statement of financial condition.

<PAGE>
                    UNITED STATES INCOME TAX CONSIDERATIONS

    The following summary describes the material U.S. federal income tax
consequences of the exchange of the initial notes for exchange notes that may be
relevant to a beneficial owner of initial notes that is a citizen or resident of
the United States or a U.S. domestic corporation or that otherwise is subject to
United States federal income taxation on a net income basis in respect of such
initial notes. This summary is based on laws, regulations, rulings and judicial
and administrative decisions now in effect, all of which are subject to change.
This summary deals only with investors that hold the initial notes as capital
assets, and does not address tax considerations applicable to investors that may
be subject to special tax rules, such as, but not limited to, banks, tax-exempt
entities, insurance companies or dealers in securities or currencies, traders in
securities electing to mark to market, persons that hold the initial notes as a
position in a "straddle" or conversion transaction, or as part of a "synthetic
security" or other integrated financial transaction or persons that have a
"functional currency" other than the U.S. dollar.

    The exchange of initial notes for exchange notes pursuant to the exchange
offer will not be a taxable event for U.S. federal income tax purposes. As a
result, a U.S. holder of an initial note whose initial note is accepted in the
exchange offer will not recognize gain or loss on the exchange for U.S. federal
income tax purposes. Such holder's tax basis in the exchange notes will be equal
to such holder's tax basis in the initial notes exchanged therefor, and the
holding period for the exchange notes received pursuant to the exchange offer
will include the holder's holding period for the initial notes surrendered
therefor.

    Investors should consult their own tax advisors in determining the tax
consequences to them, as a result of their individual circumstances, of the
exchange of initial notes for exchange notes and of the ownership and
disposition of exchange notes received in the exchange offer, including the
application of state, local, foreign or other tax laws.

                              PLAN OF DISTRIBUTION

    Each broker-dealer that receives exchange notes for its own account in
exchange for initial notes pursuant to the exchange offer, where such initial
notes were acquired by such broker-dealer as a result of market making
activities or other trading activities, must acknowledge that it will deliver a
prospectus in connection with any resale of such exchange notes. This
prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of exchange notes received in
exchange for initial notes where such initial notes were acquired as a result of
market-making activities or other trading activities. We have agreed that, for a
period of up to six-months, we will make this prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any such
resale. In addition, until       , 1999, all dealers effecting transactions in
the exchange notes may be required to deliver a prospectus.

    We will not receive any proceeds from any sale of exchange notes by
broker-dealers. Exchange notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the exchange notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or at negotiated prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer or the purchasers of any such exchange notes. Any broker-dealer
that resells exchange notes that were received by it for its own account
pursuant to the exchange offer and that participates in a distribution of such
exchange notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of exchange notes and any
commission or concessions received by any such persons may be deemed to be
underwriting compensation under

                                      112
<PAGE>
the Securities Act. The letter of transmittal states that by acknowledging that
it will deliver and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act.

    For a period of up to six-months, the Company will promptly send additional
copies of this prospectus and any amendment or supplement to this prospectus to
any broker-dealer that requests such documents in the letter of transmittal. The
Company has agreed to pay all expenses incident to the exchange offer, including
the expenses of one special counsel for all of the holders of the initial notes,
other than commissions or concessions of any broker-dealers. The Company will
indemnify the holders of the initial notes, including any broker-dealers,
against certain liabilities, including liabilities under the Securities Act.

                                 LEGAL MATTERS

    The validity of issuance of the exchange notes offered hereby will be passed
upon for LaBranche & Co Inc. by Fulbright & Jaworski L.L.P., 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 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. LaBranche
& Co Inc., on a consolidated basis, is subject to federal, state and local
income taxes. Concurrently with the closing of the common stock offering, the
Partnership completed the following Reorganization Transactions:

    - The limited partners of LaBranche & Co. redeemed their interests for
      $140.2 million in cash, a $16.0 million note, $350,000 of subordinated
      indebtedness and 558,666 shares of common stock of LaBranche & Co Inc.
      with a value of $7.8 million, for a total purchase price of $164.4
      million.

    - The members of LaB Investing Co. L.L.C. exchanged their membership
      interests in LaB Investing Co. L.L.C. for $9.0 million in cash and
      34,816,334 shares of common stock of LaBranche & Co Inc.

    - $5.0 million of subordinated debt at an interest rate of 10.0% was repaid.

    In addition, simultaneously with the initial public offering, LaBranche & Co
Inc. incurred indebtedness with a principal amount of $100.0 million. The
proceeds of the indebtedness, net of estimated issuance costs of approximately
$2.5 million, were used to redeem a portion of the limited partners' interests
in LaBranche & Co. and withdrawing members' interests.

    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:

    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 became employees of the corporation. The Board of
Directors of LaBranche & Co Inc. approved the LaBranche & Co Inc. Annual
Incentive Plan (the "Plan"). 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 the common stock 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.

                    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.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND DESCRIPTION OF BUSINESS

    The consolidated financial statements include the accounts of LaB Investing
Co. L.L.C. ("LaB Investing"), a New York limited liability company and its
subsidiary LaBranche & Co., a New York limited partnership (collectively, the
"Partnership"). LaB Investing is the general partner of LaBranche & Co. and has
a partnership interest in LaBranche & Co. of 69.7%. Limited partners own the
remaining 30.3% of LaBranche & Co. LaBranche & Co. operates primarily as a
specialist on the New York Stock Exchange, Inc. ("NYSE").

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
the date of the consolidated financial statements and the reported amounts of
revenues and expenses during the reporting period. Management does not believe
that actual results will differ materially from these estimates.

INTANGIBLE ASSETS

    Intangible assets are 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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

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.

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 .24 to 1, respectively.

    The NYSE also requires members registered as regular specialists to
establish that they can meet, with their own net liquid assets, a minimum dollar
amount which shall be the greater of $1,000,000 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:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

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.

    The Partnership 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 provision unless at least seven months notice
is given by the lender.

    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.

                         NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION AND DESCRIPTION OF BUSINESS

    LaBranche & Co. ("LaBranche") was formed as a limited partnership, under the
New York Uniform Limited Partnership Act. LaBranche operates primarily as a
specialist in certain equity securities listed on the New York Stock Exchange,
Inc. ("NYSE").

    LaBranche's general partner is LaB Investing Co. L.L.C. ("LaB"), a New York
limited liability company, which owns 69.7% of LaBranche. The remaining 30.3% is
owned by limited partners. The individual members of LaB are managing directors
of LaBranche.

2. INTERIM FINANCIAL STATEMENTS AND FINANCIAL INFORMATION

       The unaudited interim financial information as of June 30, 1999 and for
   the six months ended June 30, 1999 and 1998, is presented in the accompanying
   financial statements. The unaudited interim 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 financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the 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.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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 .24 to 1, respectively.

    The NYSE also requires members registered as regular specialists to
establish that they can meet, with their own net liquid assets, a minimum dollar
amount which shall be the greater of $1,000,000 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:

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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 unless 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.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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.

                          FOWLER, ROSENAU & GEARY, LLC

                         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:

</TABLE>

(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.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 145(a) of the General Corporation Law of the State of Delaware
("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, 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 he 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 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 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.

                                      II-1
<PAGE>
    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 has entered into indemnification agreements with its current
directors and executive officers. The Company has agreed 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 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 underwriting agreement filed as
Exhibit 1.1 hereto.

ITEM 22. 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

                                      II-3
<PAGE>
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 respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

    The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

<PAGE>

         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 herein and in the
         Prospectus;

                  (j) 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 any securities under the Registration
         Statement;

                  (k) The consolidated historical financial statements and
         schedule of the Company and its consolidated Subsidiary 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. The selected financial data set forth
         under the captions "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 therein. The pro forma financial statements
         included in the Prospectus and the Registration Statement are based on
         assumptions that provide a 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;

                  (l) There are no legal or governmental proceedings pending
         against the Company or, to the knowledge of the Company, threatened
         against it or either of its Subsidiaries or to which any of the
         respective properties of the Company or its Subsidiaries is subject
         that are not adequately disclosed in the Registration Statement or the
         Prospectus and that, if adversely decided would be expected to have a
         Material Adverse Effect or materially adversely affect the issuance of
         the Securities or the consummation of any of the transactions
         contemplated by this Agreement or the Reorganization Transactions or
         the Related Transactions. There are no agreements, contracts,
         indentures, leases or other instruments of the Company or either of its
         Subsidiaries that are material to the Company and its Subsidiaries,
         taken as a whole, that are not described in the Prospectus. Except as
         disclosed in the Prospectus, neither the Company nor either of its
         Subsidiaries is involved in any strike, job action or labor dispute
         with any group of its employees that would reasonably be expected to
         have a Material Adverse Effect, and, to the knowledge of the Company,
         no such action or dispute is threatened;

                  (m) Each of the Company and each of its Subsidiaries owns or
         leases all such properties as are materially 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;

                  (n) Neither the Company nor any Subsidiary is in violation or
         default of, and none of (x) the issuance, offer, sale or delivery of
         the Securities, (y) the execution, delivery or performance of this
         Agreement and the Related Agreements by the Company to the extent a
         party thereto, or (z) the consummation by the Company of the
         Reorganization Transactions, the Related Transactions or the
         transactions contemplated hereby or thereby will conflict with or
         constitute a breach of any of the terms or provisions of, or a default
         under, (i) the organizational documents of the Company or any of its
         Subsidiaries, or, (ii) any agreement, indenture, lease or other
         instrument to which any of the Company or its Subsidiaries is a party
         or by which any of them or any of their respective properties may be
         bound, except as disclosed in the Prospectus or any such conflicts,
         breaches or defaults that individually or in the aggregate could not
         reasonably be expected to have a Material Adverse Effect, or (iii) any
         statute, law, regulation or judgment, injunction, order or decree
         applicable to the Company or either of its Subsidiaries or any of their
         respective properties, except any such violations that in the aggregate
         could not reasonably be expected to have a Material Adverse Effect; the
         consummation of the transactions contemplated in this Agreement, the
         Reorganization Transactions and the Related Transactions will not
         result in the creation or imposition of any lien, charge or encumbrance
         upon any property or assets of any of the Company or its Subsidiaries
         pursuant to the terms of any agreement or instrument to which any of
         them may be bound or to which any of their respective properties or
         assets is subject, other than liens, charges and encumbrances disclosed
         in the Prospectus or which could not reasonably be expected to have a
         Material Adverse Effect;

                  (o) Arthur Andersen LLP, who have certified certain financial
         statements of the Company and its consolidated Subsidiary and delivered
         their reports with respect to the audited consolidated financial
         statements and schedule included in the Prospectus, are independent
         public accountants with respect to the Company within the meaning of
         the Act and the applicable published rules and regulations thereunder;

                  (p) Sugarman & Thrope, P.C., who have certified certain
         financial statements of Fowler, Rosenau & Geary LLC ("FOWLER")
         delivered their report with respect to the audited financial statements
         included in the Prospectus, are independent public accountants with
         respect to Fowler within the meaning of the Act and the applicable
         published rules and regulations thereunder;

                  (q) 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;

                  (r) The Company and each of its Subsidiaries are insured by
         insurers of recognized financial responsibility against such losses and
         risks and in such amounts as are prudent and customary in the
         businesses in which they are engaged; all policies of insurance and
         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,
         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);

                  (s) 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;

                  (t) The Company and its Subsidiaries (i) have such
         concessions, permits, licenses, consents, exemptions, franchises,
         authorizations, orders, registrations, qualifications and other
         approvals (each, an "AUTHORIZATION") of, and have made all material
         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 and (ii) 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, in each case, as are necessary to consummate the
         Reorganization Transactions and the Related Transactions and to conduct
         their respective businesses as described in the Prospectus. Each such
         Authorization is valid and in full force and effect and the Company and
         each of its Subsidiaries is in material 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 limitation of the rights of the holder of any
         such Authorization; and other than as disclosed in the Prospectus, such
         Authorizations do not contain net capital or other requirements which
         are materially more burdensome than those imposed on LaBCo. and LaBLLC
         immediately prior to the consummation of the Reorganization
         Transactions and Related Transactions;

                  (u) The statistical and market-related data included in the
         Prospectus are based on or derived from sources that the Company
         believes to be reliable and accurate;

                                       7
<PAGE>

                  (v) The Company and each of its Subsidiaries maintain a system
         of internal accounting controls sufficient to provide reasonable
         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;

                  (w) 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;

                  (x) Each of the Company, its Subsidiaries and its ERISA
         Affiliates has fulfilled its obligations, if any, under the minimum
         funding standards of Section 302 of the United States Employee
         Retirement Income Security Act of 1974 ("ERISA") and Section 412 of the
         Internal Revenue Code of 1986, as amended (the "CODE") and the
         regulations and published interpretations thereunder with respect to
         each "plan" (as defined in Section 3(3) of ERISA) for which the Company
         or any of its Subsidiaries or ERISA Affiliates have or may have any
         liability (contingent or otherwise) and each such plan is in compliance
         in all material respects with the applicable provisions of ERISA and
         the Code and such regulations and published interpretations thereunder.
         Neither the Company nor any of its Subsidiaries or ERISA Affiliates
         have incurred any 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. Neither the
         Company nor any of its Subsidiaries has engaged in any non-exempt
         "prohibited transaction" under ERISA or the Code. The term "ERISA
         AFFILIATE" means each trade or business (whether or not incorporated)
         that would be treated as a single employer with the Company under Title
         IV of ERISA or Section 412 of the Code;

                  (y) 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;

                  (z) The statements set forth under the headings "Management's
         Discussion and Analysis of Financial Condition and Results of
         Operations--Year 2000" and "Risk Factors--Year 2000 compliance problems
         could cause our trading-related communications and data processing
         systems to fail, which could result in losses" accurately and fairly
         set forth the current state of the Company's efforts to address the
         Year 2000 Problem and the risks and costs of the Company relating to
         the Year 2000 Problem. The "YEAR 2000 PROBLEM" as used herein means any
         significant risk that computer hardware or software used in the
         receipt, transmission, processing, manipulation, storage, retrieval,
         transmission or other utilization of data or in the operation of
         mechanical or electrical systems of any kind will not, in the case of
         dates or


                                       8

         time periods occurring after December 31, 1999, function at
         least as effectively as in the case of dates or time periods
         occurring prior to January 1, 2000;

                  (aa) 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 or the Related
         Transactions, to register any such securities under the Act, or to
         qualify any indenture under the Trust Indenture Act of 1939, as
         amended;

                  (bb) LaBCo. is registered as a broker-dealer with the SEC
         under the Exchange Act and LaBCo. is a member organization in good
         standing with the NYSE. LaBCo. is not required to be registered with
         the Securities authorities of any state;

                  (cc) LaBCo. is a broker-dealer subject to the provisions of
         Regulation T (12 C.F.R. Section 220) of the Board of Governors of the
         Federal Reserve System. LaBCo. maintains procedures and internal
         controls designed to ensure that it does not extend or maintain 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 LaBCo., and the activities of its
         employees, to ensure that LaBCo. does not extend or maintain credit to
         or for its customers other than in accordance with the provisions of
         said Regulation T;

                  (dd) The Company and its Subsidiaries own, possess, license or
         have other rights to use, on reasonable terms, all patents, patent
         applications, trade and service marks, trade and service mark
         registrations, trade names, copyrights, licenses, inventions, trade
         secrets, technology, know-how and other intellectual property
         (collectively, the "INTELLECTUAL PROPERTY") necessary for the conduct
         of the Company's business as now conducted or as proposed in the
         Prospectus to be conducted, except any failure to so own, possess,
         license or have rights to use Intellectual Property which would not
         have a Material Adverse Effect; and

                  (ee) The Company has not offered, or caused the Underwriters
         to offer, Shares to any person pursuant to the Directed Share Program
         with the specific intent to unlawfully influence (i) a customer or
         supplier of the Company to alter the customer's or supplier's level or
         type of business with the Company, or (ii) a trade journalist or
         publication to write or publish favorable information about the Company
         or its products.

                  Furthermore, in the event that Directed Shares are sold
outside the United States, the Company represents and warrants to Salomon Smith
Barney that (i) the Registration Statement, the Prospectus and any preliminary
prospectus comply, and any further amendments or supplements thereto will
comply, with any applicable laws or regulations of foreign jurisdictions in
which the Prospectus or any preliminary prospectus, as amended or supplemented,
if applicable, are distributed in connection with the Directed Share Program,
and that (ii) no authorization, approval, consent, license, order, registration
or qualification of or with any government, governmental instrumentality or
court, other than such as have been obtained, is necessary under the securities
laws and regulations of foreign jurisdictions in which the Directed shares are
offered outside the United States.

                  Any certificate signed by any officer of the Company and
delivered to the Representatives or counsel for the Underwriters in connection
with the offering of the Securities shall be deemed a representation and
warranty by the Company, as to matters covered thereby, to each Underwriter.

                  2. PURCHASE AND SALE. (a) Subject to the terms and conditions
and in reliance upon the representations and warranties herein set forth, the
Company agrees to sell to each Underwriter, and each Underwriter agrees,
severally and not jointly, to purchase from the Company, at a purchase price of
$14.00 per share, the amount of the Underwritten Securities set forth opposite
such Underwriter's name in SCHEDULE I hereto.

                  (b) Subject to the terms and conditions and in reliance upon
the representations and warranties herein set forth, the Company hereby grants
an option to the several Underwriters to purchase, severally and not jointly, up
to 1,575,000 Option Securities at the same purchase price per share as the
Underwriters shall pay for the Underwritten Securities. Said option may be
exercised only to cover over-allotments in the sale of the Underwritten
Securities by the Underwriters. Said option may be exercised in whole or in part
at any time (but not more than once) on or before the 30th day after the date of
the Prospectus upon written or telegraphic notice by the Representatives to the
Company setting forth the number of shares of the Option Securities as to which
the several Underwriters are exercising the option and the settlement date. The
number of Option Securities to be purchased by each Underwriter shall be the
same percentage of the total number of shares of the Option Securities to be
purchased by the several Underwriters as such Underwriter is purchasing of the
Underwritten Securities, subject to such adjustments as you in your absolute
discretion shall make to eliminate any fractional shares.

                  3. DELIVERY AND PAYMENT. Delivery of and payment for the
Underwritten Securities and the Option Securities (if the option provided for in
Section 2(b) hereof shall have been exercised on or before the third Business
Day prior to the Closing Date) shall be made at 10:00 AM, New York City time, on
August 24, 1999, or at such time on such later date not more than three Business
Days after the foregoing date as the Representatives shall designate, which date
and time may be postponed by agreement between the Representatives and the
Company or as provided in Section 9 hereof (such date and time of delivery and
payment for the Securities being herein called the "CLOSING DATE"). Delivery of
the Securities shall be made to the Representatives for the respective accounts
of the several Underwriters against payment by the several Underwriters through
the Representatives of the purchase price thereof to or upon the order of the
Company by wire transfer payable in same-day funds to an account specified by
the Company. Delivery of the Underwritten Securities and the Option Securities
shall be made through the facilities of The Depository Trust Company unless the
Representatives shall otherwise instruct.

                  If the option provided for in Section 2(b) hereof is exercised
after the third Business Day prior to the Closing Date, the Company will deliver
the Option Securities (at the expense of the Company) to the Representatives, at
388 Greenwich Street, New York, New York, on the date specified by the
Representatives (which shall be within three Business Days after exercise of
said option) for the respective accounts of the several Underwriters, against
payment by the several Underwriters through the Representatives of the purchase
price thereof to or upon the order of the Company by wire transfer payable in
same-day funds to an account



                                       10

specified by the Company. If settlement for the Option Securities occurs after
the Closing Date, the Company will deliver to the Representatives on the
settlement date for the Option Securities, and the obligation of the
Underwriters to purchase the Option Securities shall be conditioned upon receipt
of, supplemental opinions, certificates and letters confirming as of such date
the opinions, certificates and letters delivered on the Closing Date pursuant to
Section 6 hereof.

                  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 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,



                                       11
<PAGE>

         (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

         subject.

         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

         Company to facilitate the sale or resale of the Securities.

                  thereto or (z) the consummation of the Reorganization
                  Transactions and the Related Transactions will not conflict
                  with or constitute a breach of any of the terms or provisions
                  of, or a default under, (i) the organizational documents of
                  the Company or any of its Subsidiaries, or (ii) any of the
                  Material Contracts or (iii) any statute, law, ordinance or
                  administrative, governmental or self-regulatory organization,
                  rule or regulation known to such counsel to be applicable to
                  the Company or any Subsidiary or any of their respective
                  properties or any filing of judgment, injunction, order or
                  decree of any court or governmental agency or body having
                  jurisdiction over the Company or any Subsidiary or any of
                  their properties; and the consummation of the transactions
                  contemplated herein, the Reorganization Transactions and the
                  Related Transactions will not result in the creation or
                  imposition of any lien, charge or encumbrance upon any
                  property or assets of the Company or any Subsidiary pursuant
                  to the terms of any Material Contract, other than as disclosed
                  in the Prospectus; PROVIDED, HOWEVER, that, for the purposes
                  of this paragraph (xi), insofar as the consummation of the
                  Reorganization Transactions and Related Transactions are

                  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

                  opinion) as have been obtained;

                           (xiii) there are no transfer taxes or other similar

                  connection with the execution and delivery of this Agreement
                  or the issuance by the Company or sale by the Company of the
                  Securities;

                           (xiv) the Material Contracts do not contain any
                  provisions that prohibit any Subsidiary of the Company,
                  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;

                           (xv) 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 and the Related Transactions, to register any
                  such securities under the Act, or to qualify any indenture

                           (xvii) to the knowledge of such counsel, 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.

         Such counsel's opinion shall also include a paragraph substantially in
         the form set forth in EXHIBIT B hereto.

         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



                                       17
<PAGE>

         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, Chief Executive
         Officer and President and the principal financial officer of the
         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 in all material respects 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, 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 periods ended
         June 30, 1999 and 1998, 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
                  and financial statement schedule 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, and nothing has come to
                  their attention which caused them to believe that the pro
                  forma financial statements included in the Registration
                  Statement and the Prospectus and reported on by them did not
                  comply as to form with the requirements of Rule 11-02 of
                  Regulation S-X;

                           (ii) on the basis of a reading of the latest
                  unaudited financial statements made available by the Company
                  and its Subsidiary; their limited review, in



                                       18
<PAGE>

                  accordance with standards established under Statement on
                  Auditing Standards No. 71, of the unaudited interim financial
                  information for the six-month periods ended June 30, 1999 and
                  1998, and as at June 30, 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
                  (if any) of the meetings of the stockholders and directors of
                  the Company, the partners of LaBCo. and the Managing Committee
                  of LaBLLC; 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 was any increase, at a specified
                           date not more than five days prior to the date of the
                           letter, in the subordinated indebtedness of the
                           Company and its Subsidiary or decreases in the
                           members' capital 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 the corresponding period for the
                           prior fiscal year in total revenues, income before
                           managing directors' compensation, limited partners'
                           interest in earnings of subsidiary and provision for
                           unincorporated business taxes or income before
                           limited partners' interest in earnings of subsidiary
                           and provision for unincorporated business taxes
                           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 financial information included in
                           the Registration Statement and Prospectus in response
                           to Regulation S-K, Item 301 (Selected Financial Data)
                           and Item 302 (Supplementary Financial Information) is
                           not in conformity with the applicable disclosure
                           requirements of Regulation S-K; and

                           (iii) they have performed certain other specified
                  procedures requested by the Underwriters 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 review 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 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 report shall be included in the Registration
         Statement.

                  The Company shall have received from Arthur Andersen LLP (and
         furnished to the Representatives) a review report with respect to the
         pro forma adjustments described in the Pro Forma Consolidated Financial
         Information (Unaudited)--Overview and the application of those
         adjustments to the historical amounts included in the Registration
         Statement and the Prospectus.

                  (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, 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. 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



                                       20
<PAGE>

         (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
         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 cancellation 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



                                       21
<PAGE>

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 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; PROVIDED FURTHER, that with respect to any
untrue statement or omission of material fact made in any Preliminary
Prospectus, the indemnity agreement contained in this Section 8(a) shall not
inure to the benefit of any Underwriter from whom the person asserting any such
loss, claim, damage or liability purchased the securities concerned, to the
extent that any such loss, claim, damage or liability of such Underwriter occurs
under the circumstance where it shall have been determined by a court of
competent jurisdiction by final and nonappealable judgment that (w) the Company
had previously furnished copies of the Prospectus to the Representatives, (x)
delivery of the Prospectus was required by the Act to be made to such person,
(y) the untrue statement or omission of a material fact contained in the
Preliminary Prospectus was corrected in the Prospectus and (z) there was not
sent or given to such person, at or prior to the written confirmation of the
sale of such securities to such person, a copy of the Prospectus. 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 the last paragraph of the cover page regarding delivery of the
Securities and, under the heading "Underwriting", (i) the list of Underwriters
and their respective participation in the sale of the Securities, (ii) the
sentences



                                       22
<PAGE>

related to concessions and reallowances, (iii) the paragraphs related to
stabilization, syndicate covering transactions and penalty bids and (iv) the
paragraph related to the Directed Share Program of 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 reasonably 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 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 reasonably 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.
Notwithstanding anything contained herein to the contrary, if indemnity may be
sought pursuant to Section 8(e) hereof in respect of such action or proceeding,
then in addition to such separate firm for the indemnified parties, the
indemnifying party shall be liable for the reasonable fees and expenses of not
more than one separate firm (in addition to any local counsel) for Salomon Smith
Barney for the defense of any losses, claims, damages and liabilities arising
out of the Directed Share Program, and all persons, if any, who control Salomon
Smith Barney within the meaning of either Section 15 of the Act or Section 20 of
the Exchange Act.

                  (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
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).

                  (e) The Company agrees to indemnify and hold harmless Salomon
Smith Barney and each person, if any, who controls Salomon Smith Barney within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act ("SALOMON SMITH BARNEY ENTITIES"), from and against any and all
losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) (i) in the event that Directed Shares
are sold outside the United States, caused by any untrue statement or alleged
untrue statement of a material fact contained in the prospectus wrapper material
prepared by or with the consent of the Company for distribution in foreign
jurisdictions in connection with the Directed Share Program attached to the
Prospectus or any preliminary prospectus, or caused by any omission or alleged
omission to



                                       24
<PAGE>

state therein a material fact required to be stated therein or necessary to make
the statement therein, when considered in conjunction with the Prospectus or any
applicable preliminary prospectus, not misleading; (ii) caused by the failure of
any Participant to pay for and accept delivery of the shares which immediately
following the effective of the Registration Statement, were subject to a
properly confirmed agreement to purchase; or (iii) related to, arising out of,
or in connection with the Directed Share Program, provided that, the Company
shall not be responsible under this subparagraph (iii) for any losses, claim,
damages or liabilities (or expenses relating thereto) that are finally
judicially determined to have resulted from the bad faith or gross negligence of
Salomon Smith Barney Entities.

                  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



                                       25
<PAGE>

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 cancellation of this Agreement.

                  12. NOTICES. All communications hereunder will be in writing
and effective only on receipt, and, if sent to the Representatives, will be
mailed, delivered or telefaxed to the Salomon Smith Barney General Counsel (fax
no.: (212) 816-7912) and confirmed to Salomon Smith Barney, at 388 Greenwich

the Company, will be mailed, delivered or telefaxed to (212) 344-1469 and
confirmed to it at One Exchange Plaza, New York, New York 10006, attention of
the Legal Department.

                  13. SUCCESSORS. This Agreement will inure to the benefit of
and be binding upon the parties hereto and their respective successors and the
officers, directors, employees, agents and controlling persons referred to in
Section 8 hereof, and no other person will have any right or obligation
hereunder.

                  14. APPLICABLE LAW. This Agreement will be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed within the State of New York.

                  15. COUNTERPARTS. This Agreement may be signed in one or more
counterparts, each of which shall constitute an original and all of which
together shall constitute one and the same agreement.

                  16. HEADINGS. The section headings used herein are for

                  We have participated in conferences with officers and other
representatives of the Company, representatives of the independent public
accountants for the Company, representatives of the Underwriters and counsel for
the Underwriters at which conferences the contents of the Prospectus and the
Registration Statement and related matters were discussed, and, although we have
not independently verified and are not passing upon and assume no responsibility
for the accuracy, completeness or fairness of the statements contained in the
Prospectus (except to the extent required in paragraph iv of Section 6 of the
Underwriting Agreement ), and that our judgment as to materiality is, to the
extent we deem proper, based in part upon the views of appropriate officers and
other representatives of the Company, nothing has come to our attention that
leads us to believe that the Registration Statement, as of its date and on the
Closing Date, contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements contained therein not misleading or that the Prospectus, as of its
date and on the Closing Date, included or includes an untrue statement of a
material fact or omitted or to omits to state a material fact required to be
stated therein or necessary to make the statements contained therein, in the
light of the circumstances under which they were made, not misleading (in each
case, it being understood that we express no opinion with respect to the
financial statements and related notes thereto and the other financial,
statistical and accounting data included therein).

                                  INTRODUCTION

GENERAL

                  This is the Plan of Incorporation, dated as of June 17, 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 delivering





<PAGE>



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
Incorporation


                                      -2-
<PAGE>



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 some or all of 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 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.

                  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.

                                      -8-
<PAGE>



                  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 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

                                      -9-
<PAGE>



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 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

                                      -10-
<PAGE>



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.

HEADINGS

                  The headings of the Sections and paragraphs of this Plan 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
Plan or the intent of any Section or paragraph.

                               EXCHANGE AGREEMENT


         This EXCHANGE AGREEMENT (this "AGREEMENT") is dated as of June 17,
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");

         WHEREAS, in contemplation of the IPO, the Company, Investing, LaBranche
& Co., a New York limited partnership ("LABRANCHE LP"), and the limited partners
of LaBranche LP (collectively, the "PARTICIPATING LIMITED PARTNERS") have
simultaneously herewith approved, adopted and entered into a Plan of
Incorporation, (the "PLAN"), dated as of June 17, 1999, pursuant to which, among
other things, the Participating Limited Partners have agreed to exchange their
partnership interests in LaBranche LP for cash and/or securities of the Company
and/or LaBranche LP; and

         WHEREAS, in contemplation of the IPO, the Exchanging Members desire to
transfer their respective membership interests in Investing (collectively,
"MEMBERSHIP INTERESTS") to the Company in exchange for shares of Common Stock
or, in the case of certain Exchanging Members, a combination of cash and/or
securities of the Company (the "LLC EXCHANGE");

         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:

and interest in, to and with respect to his or her entire Membership Interest.

Interest and hereby assumes and

obligations of such Exchanging Member pursuant to the LaB Investing Co. L.L.C.
Amended and Restated Operating Agreement, dated as of January 1, 1998, as
amended to date (the "LLC AGREEMENT").

                  (c) Immediately after the Effective Time, each Exchanging
Member shall receive, in consideration for the exchange of his or her Membership
Interest, the number of shares of Common Stock (or, in the case of Steven C.
Berger, Paul Redmond and Robert W. Keelips, III , a combination of shares of
Common Stock and cash) with a value, based upon the per share price of the
Common Stock in the IPO, equal to such Exchanging Member's interest in that
portion of the public market valuation of the Company available to the members
of Investing.1/

                  (d) The Company will issue to an Exchanging Member, as
applicable, only whole shares of Common Stock. As a result, such an Exchanging
Member will receive cash in lieu of any fractional share interest in Common
Stock.

         Section 1.2. TERMINATION OF RIGHTS. From and after the Effective Time,
the entire capital account and share of profits and losses of each Exchanging
Member shall be deemed to be the capital account and share of profits and losses
of the Company, and such Exchanging Member shall have no further interest or
rights of any kind in or with respect to his or her Membership Interest or under
the LLC Agreement. From and after the Effective Time, the Company shall be the
sole member of Investing, and each Exchanging Member shall be released from all
further obligations under the LLC Agreement.

         Section 1.3. CONSENT OF MANAGING COMMITTEE. By its execution hereof,
Investing acknowledges that the Managing Committee of Investing (the "MANAGING
COMMITTEE") (i) has approved the form of this Agreement, (ii) acknowledges
receipt of a duly executed copy of this Agreement and (iii) in accordance with
the provisions of the LLC Agreement, consents to the assignment and transfer of
the Exchanging Members' Membership Interests to the Company and to the admission
of the Company as a new member of Investing.

         Section 1.4. EFFECTIVE TIME. Subject to the consummation of the IPO,
the LLC Exchange shall be deemed to occur immediately prior to the IPO. The date
and time when the LLC Exchange shall be deemed to occur is referred to in this
Agreement as the "EFFECTIVE TIME."


- --------
1/ An estimated value of each Exchanging Member's interest is set forth on
SCHEDULE A hereto opposite such Exchanging Member's name under the column
entitled "Total Assumed Value." These estimated values are based on a current
estimate of $425 million, which is subject to change, as the portion of the
public market valuation of the Company available to the members of Investing.

                         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").

         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


                                      -3-
<PAGE>



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.

this Agreement in any respect prior to the Effective Time, including making any
amendments to the Exhibits hereto; provided that an amendment shall not be
binding upon an Exchanging Member if it would (a) disproportionately reduce the
value of the shares of Common Stock and/or cash, as the case may be, to be
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.
Keelips, III), or (b) amend the LLC Agreement in a manner that would require the
further consent of such Exchanging Member without obtaining the consent of such

                  (b) The Managing Committee has the authority under this
Agreement not to offer securities of the Company to or exchange securities of
the Company with any member of Investing if the Managing Committee 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. In the event the Managing Committee does not so offer or
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
amended (the "INVESTING OPERATING AGREEMENT"), require such member of Investing

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

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.

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

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

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 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.

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

              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
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)



                                      -2-
<PAGE>


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. 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 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



                                      -3-
<PAGE>

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 anydirectorships 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 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.



                                      -4-

         (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, (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




                                      -5-
<PAGE>



         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.

         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



                                      -6-
<PAGE>




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
of a majority of the total number of directors which the Corporation would have
if there were no vacancies. Such request or order shall state the purposes of
the proposed meeting. The Chairman of the Board of Directors of the Corporation
or directors so calling 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 2.05.   NOTICE OF MEETING. Written notice of the annual, and
each special meeting of stockholders, stating the time, place, and purpose or
purposes thereof, shall be given to each stockholder entitled to vote thereat,

          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

provided by statute or by the Certificate of Incorporation. Notwithstanding the
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
present or represented. If the adjournment is for more than 30 days, or if after
the adjournment a new record date is fixed for the adjourned meeting, a notice
of the adjourned meeting shall be given to each stockholder of record entitled
to vote at the meeting. At such adjourned meeting at which a quorum shall be
present or represented, any business may be transacted which might have been

          SECTION 2.07.   VOTING. When a quorum is present at any meeting of the
stockholders, the vote of the holders of a majority of the shares of the
Corporation's capital stock having voting power present in person or represented
by proxy shall decide any question brought before such meeting, unless the
question is one upon which, by express provision of the statutes, of the
Certificate of Incorporation or of these bylaws, a different vote is required,
in which case such express provision shall govern and control the decision of
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-

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

          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.

such time and place as the Board of Directors may provide, by resolution, either
within or without the State of Delaware, without other notice than such
resolution.

          SECTION 3.05.   SPECIAL MEETING. A special meeting of the Board of
Directors may be called by the Chairman of the Board of Directors or by the
President of the Corporation and shall be called by the Secretary on the written
request of any two directors. The Chairman or President so calling, or 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
without a meeting, if a written consent thereto is signed by all members of the
Board of Directors or of such committee, as the case may be, and such written
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

the powers of the Board of Directors in the management of the business and
affairs of the Corporation as may be provided in such resolution. The committee
may authorize the seal of the Corporation to be affixed to all papers that may
require it. The 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-

names and such limitations of authority as may be determined from time to time

of Directors. Any two or more offices may be held by the same person. No officer

such removal shall be without prejudice to the contractual rights, if any, of
the person so removed. Any officer may resign at any time by giving written
notice to the Corporation. Any such resignation shall take effect at the date of

otherwise specified therein, the acceptance of such resignation shall not be
necessary to make it effective.

Chairman of the Board of Directors or the Vice Chairman of the Board of
Directors (if such office is created by the Board of Directors), the Chief
Executive Officer shall preside at all meetings of the Board of Directors and of
the stockholders. The Chief Executive Officer may also preside at any such

                         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

                                 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 any action, suit, or proceeding referred
to in Sections 10.01 and 10.02, or in defense of

                                     -12-
<PAGE>


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
Board of Directors, shall have inscribed thereon the name of the Corporation,
and the words "Corporate Seal, Delaware." The seal may be used by causing it or
a facsimile thereof to be impressed or affixed or otherwise reproduced.

          SECTION 11.02.  BOOKS. The books of the Corporation may be kept
(subject 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 designated from time to time by the Board of Directors.

                                  ARTICLE XII

                                   AMENDMENT

          Except as provided in Article Sixth of the Certificate of
Incorporation, these bylaws may be altered, amended, or repealed by a majority
of the number of directors then constituting the Board of Directors at any
regular meeting of the Board of Directors without prior notice, or at any
special meeting of the Board of Directors if notice of such alteration,
amendment, or repeal be contained in the notice of such special meeting.

                                   ARTICLE II.

                                    THE NOTES

                  Section 2.1. FORM AND DATING.

                  (a) The Notes are being originally offered and sold by
the Company pursuant to a purchase agreement, dated August 18, 1999 among the
Company, Salomon Smith Barney Inc. and Donaldson, Lufkin & Jenrette Securities
Corporation. The Company may issue up to $100,000,000 aggregate principal amount
of the Notes as provided in this Indenture. The Notes will be issued in
fully-registered form without coupons, and only in denominations of $1,000 and
any integral multiple thereof. The Notes and the Trustee's certificate of
authentication shall be substantially in the form of EXHIBIT A hereto.

                  (b) The terms and provisions of the Notes, the form of
which is in EXHIBIT A hereto, shall constitute, and are hereby expressly made, a
part of this Indenture, and, to the extent applicable, the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby. Except as otherwise expressly
permitted in this Indenture, all Notes shall be identical in all respects.
Notwithstanding any differences among them, all Notes issued under this
Indenture shall vote and consent together on all matters as one class.

                  (c) The Notes may have notations, legends or endorsements
as specified in Section 2.7 or as otherwise required by law, stock exchange rule
or the Depository rule or usage. The Company and the Trustee shall approve the
form of the Notes and any notation, legend or endorsement on them. Each Note
shall be dated the date of its authentication.



                                       26
<PAGE>

                  (d) Notes originally offered and sold to QIBs in reliance
on Rule 144A will be issued on the issue date therefor in the form of a
permanent Global Note ("RULE 144A GLOBAL NOTES").

                  (e) Notes originally offered and sold outside the United
States of America in reliance on Regulation S will be issued on the issue date
therefor in the form of a temporary Global Note (a "REGULATION S TEMPORARY
GLOBAL NOTE"). An interest in a Regulation S Temporary Global Note will be
exchangeable for an interest in a permanent Global Note (a "REGULATION S
PERMANENT GLOBAL NOTE", and together with the Regulation S Temporary Global
Note, a "REGULATION S GLOBAL NOTE") on or after the expiration of the
Distribution Compliance Period upon the receipt by the Registrar of a
certificate in the form of EXHIBIT B-1 hereto (a "NON-U.S. BENEFICIAL OWNERSHIP
CERTIFICATION") to the effect that Euroclear or Cedelbank, as applicable, has
received a certificate in the form of EXHIBIT B-2 hereto, from the holder of a
beneficial interest in such Regulation S Temporary Global Note (or its agent) in
the principal amount to be exchanged. Upon receipt by the Registrar of a
Non-U.S. Beneficial Ownership Certification, (i) with respect to the first such
Non-U.S. Beneficial Ownership Certification, the Company will execute, and upon
Company Order the Trustee will authenticate and deliver to the Custodian, the
Regulation S Permanent Global Note and (ii) with respect to the first and each
subsequent Non-U.S. Beneficial Ownership Certification, the Registrar and the
Note Custodian shall exchange the interest in the Regulation S Temporary Global
Note covered by such Non-U.S. Beneficial Ownership Certification for an interest
of equal principal amount in the Regulation S Permanent Global Note. Upon any
exchange of an interest in a Regulation S Temporary Global Note for a comparable
interest in the Regulation S Permanent Global Note, the Registrar shall decrease
the Regulation S Temporary Global Note and increase the Regulation S Permanent
Global Note, in each case in an amount equal to the principal amount of Notes
covered by the applicable Non-U.S.
Beneficial Ownership Certification.

                  Section 2.2. EXECUTION AND AUTHENTICATION.

                  (a) The Chairman and Chief Executive Officer and the
chief financial officer shall sign the Notes for the Company by manual or
facsimile signature. If an Officer whose signature is on a Note no longer holds
that office at the time the Trustee authenticates the Note, the Note shall be
valid nevertheless.

                  (b) A Note shall not be valid until an authorized
signatory of the Trustee manually authenticates the Note. The signature of the
Trustee on a Note shall be conclusive evidence that such Note has been duly and
validly authenticated and issued under this Indenture.

                  (c) At any time and from time to time after the execution
and delivery of this Indenture, the Trustee shall authenticate and make
available for delivery Notes, upon a written order of the Company signed by two
Officers or by an Officer and either an Assistant Treasurer or an Assistant
Secretary of the Company (the "COMPANY ORDER"). A Company Order shall specify
the amount of the Notes to be authenticated and the date on which the original
issue of Notes is to be authenticated.

                  (d) The Trustee may appoint an agent (the "AUTHENTICATING
AGENT") reasonably acceptable to the Company to authenticate the Notes. Unless
limited by the terms of such



                                       27
<PAGE>

appointment, any such Authenticating Agent may authenticate Notes whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by the Authenticating Agent.

                  (e) In event that the Company:

                           (i) shall be consolidated with or merged into any
                  other Person, or

                           (ii) shall convey, transfer, lease or otherwise
                  dispose of its properties and assets substantially as an
                  entirety to any Person,

and the Surviving Entity resulting from such consolidation, or surviving such
merger, or which shall have received a conveyance, transfer, lease or other
disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article V; then any of the Notes authenticated or
delivered prior to such transaction may, from time to time, at the request of
the Surviving Entity, be exchanged for other Notes executed in the name of the
Surviving Entity with such changes in phraseology and form as may be
appropriate, but otherwise identical to the Notes surrendered for such exchange
and of like principal amount; and the Trustee, upon Company Order of the
Surviving Entity, shall authenticate and deliver Notes as specified in such
order for the purpose of such exchange. If Notes shall at any time be
authenticated and delivered in any new name of a Surviving Entity pursuant to
this Section 2.2 in exchange or substitution for or upon registration of
transfer of any Notes, such Surviving Entity, at the option of the Holders but
without expense to them, shall provide for the exchange of all Notes at the time
outstanding for Notes authenticated and delivered in such new name.

                  Section 2.3. REGISTRAR AND PAYING AGENT.

                  (a) The Company shall maintain an office or agency in the
Borough of Manhattan, City of New York, where Notes may be presented for
registration of transfer or for exchange (the "REGISTRAR"), where Notes may be
presented for payment (the "PAYING AGENT") and for the service of notices and
demands to or upon the Company in respect of the Notes and this Indenture. The
Registrar shall keep a register of the Notes and of their transfer and exchange.
The Company may have one or more co-Registrars and one or more additional paying
agents. The term "Paying Agent" includes any additional paying agent.

                  (b) The Company shall enter into an appropriate agency
agreement with any Registrar, Paying Agent or co-Registrar not a party to this
Indenture, which shall incorporate the terms of the TIA. The agreement shall
implement the provisions of this Indenture that relate to such agent. The
Company shall notify the Trustee of the name and address of each such agent. If
the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act
as such and shall be entitled to appropriate compensation therefor pursuant to
Section 7.7 hereof. The Company may act as Paying Agent, Registrar, co-Registrar
or transfer agent.

                  (c) The Company initially appoints the Trustee at its
principal Corporate Trust Office as Registrar, Paying Agent and agent for
service of demands and notices in connection with the Notes and this Indenture,
until such time as the Trustee has resigned or a successor Trustee has been
appointed.

                                       28
<PAGE>

                  Section 2.4. PAYING AGENT TO HOLD MONEY IN TRUST.

                  The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that such Paying Agent shall hold in trust for the
benefit of Holders or the Trustee all money held by such Paying Agent for the
payment of principal of or interest on the Notes and shall notify the Trustee in
writing of any default by the Company in making any such payment. If the Company
acts as Paying Agent, it shall segregate the money held by it as Paying Agent
and hold it as a separate trust fund. The Company at any time may require a
Paying Agent (other than the Trustee) to pay all money held by it to the Trustee
and to account for any funds disbursed by such Paying Agent. Upon complying with
this Section 2.4, the Paying Agent (if other than the Company) shall have no
further liability for the money delivered to the Trustee. Upon any proceeding
under any Bankruptcy Law with respect to the Company or any Affiliate of the
Company, if the Company is then acting as Paying Agent, the Trustee shall
replace the Company as Paying Agent.

                  Section 2.5. HOLDER LISTS.

                  The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of Holders. If the Trustee is not the Registrar, or to the extent
otherwise required under the TIA, the Company shall furnish to the Trustee, in
writing at least seven Business Days before each Interest Payment Date and at
such other times as the Trustee may request in writing, a list in such form and
as of such date as the Trustee may reasonably require of the names and addresses
of Holders.

                  Section 2.6. GLOBAL NOTE PROVISIONS.

                  (a) Each Global Note initially shall: (i) be registered
in the name of the Depository or the nominee of the Depository, (ii) be
delivered to the Custodian, and (iii) bear the appropriate legend, as set forth
in Section 2.7 and EXHIBIT A hereto. Any Global Note may be represented by more
than one certificate. The aggregate principal amount of each Global Note may
from time to time be increased or decreased by adjustments made on the records
of the Custodian, as provided in this Indenture.

                  (b) Members of, or participants in, the Depository
("AGENT MEMBERS") shall have no rights under this Indenture with respect to any
Global Note held on their behalf by the Depository or by the Custodian under
such Global Note, and the Depository may be treated by the Company, the Trustee,
the Paying Agent and the Registrar and any of their agents as the absolute owner
of such Global Note for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Company, the Trustee, the Paying Agent or the
Registrar or any of their agents from giving effect to any written
certification, proxy or other authorization furnished by the Depository or
impair, as between the Depository and its Agent Members, the operation of
customary practices of the Depository governing the exercise of the rights of an
owner of a beneficial interest in any Global Note. The registered Holder of a
Global Note may grant proxies and otherwise authorize any person, including
Agent Members and persons that may hold interests through Agent Members, to take
any action that a Holder is entitled to take under this Indenture or the Notes.

                                       29
<PAGE>

                  (c) Except as provided in Section 2.8 and below, owners
of beneficial interests in Global Notes will not be entitled to receive
Certificated Notes. Certificated Notes shall be issued to all owners of
beneficial interests in a Global Note in exchange for such interests if:

                           (i) the Depository notifies the Company that it is
                  unwilling or unable to continue as depositary for such Global
                  Note or the Depository ceases to be a clearing agency
                  registered under the Exchange Act, at a time when the
                  Depository is required to be so registered in order to act as
                  depositary, and in each case a successor depositary is not
                  appointed by the Company within 90 days of such notice, or

                           (ii) the Company executes and delivers to the Trustee
                  and Registrar an Officers' Certificate stating that such
                  Global Note shall be so exchangeable.

In connection with the exchange of an entire Global Note for Certificated Notes
pursuant to this subsection (c), such Global Note shall be deemed to be
surrendered to the Trustee for cancellation, and the Company shall execute, and
upon Company Order the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depository in exchange for its beneficial
interest in such Global Note, an equal aggregate principal amount of
Certificated Notes of authorized denominations.

                  (d) In connection with the exchange of a portion of a
Certificated Note for a beneficial interest in a Global Note, the Trustee shall
cancel such Certificated Note, and the Company shall execute, and upon Company
Order the Trustee shall authenticate and deliver, to the exchanging Holder a new
Certificated Note representing the principal amount not so exchanged.

                  Section 2.7 LEGENDS.

                  (a) Each Global Note shall bear the legend specified therefor
in EXHIBIT A on the face thereof.

                  (b) Each Restricted Note shall bear the private placement
legend specified therefor in EXHIBIT A on the face thereof (together with, if
applicable, the legend specified in clause (d) below, the "PRIVATE PLACEMENT
LEGEND").

                  (c) Each Regulation S Temporary Global Note shall bear
the legend specified therefor in EXHIBIT A on the face thereof.

                  (d) Each Certificated Note that is a Restricted Note
shall bear the legend specified therefor in EXHIBIT A on the face thereof.

                  Section 2.8 TRANSFERS AND EXCHANGES.

proposed transfer of an interest in a Rule 144A Global Note that is a Restricted

         Global Note wishes to transfer such interest (or portion thereof) to a
         Non-U.S. Person pursuant to Regulation S and (2) such Non-U.S. Person

                           Global Note directing the Custodian and Registrar to
                           credit or cause to be credited a beneficial interest
                           in the Regulation S Global Note equal to the
                           principal amount of the beneficial interest in the
                           Rule 144A Global Note to be transferred, and

                           (B) a certificate in the form of EXHIBIT D from the
                           transferor,

         and (y) subject to the rules and procedures of DTC, the Custodian and
         Registrar shall increase the Regulation S Global Note and decrease the
         Rule 144A Global Note by such amount in accordance with the foregoing.

                  (b) The following provisions shall apply with respect to any
proposed transfer of an interest in a Regulation S Temporary Global:

                  (i) If the owner of an interest in a Regulation S Temporary
         Global Note wishes to transfer such interest (or any portion thereof)
         to a QIB pursuant to Rule 144A, (x) upon receipt by the Custodian and
         Registrar of:

                           (A) instructions from the Custodian and Holder of
                      the Regulation S Temporary Global Note directing the
                      Registrar to credit or cause to be credited a
                      beneficial interest in the Rule 144A Global Note equal
                      to the principal amount of the beneficial interest in
                      the Regulation S Temporary Global Note to be
                      transferred, and

                            (B) a certificate in the form of EXHIBIT C duly
                      executed by the transferor, and

         (y) in accordance with the rules and procedures of DTC, the Custodian
         and Registrar shall increase the Rule 144A Global Note and decrease the
         Regulation S Temporary Global Note by such amount in accordance with
         the foregoing.

                  (ii) No interest in a Regulation S Temporary Global Note will
         be transferred to a holder of an interest in the Regulation S Permanent
         Global Note except pursuant to SECTION 2.1(E).

                  (c) OTHER TRANSFERS. Any transfer of Restricted Notes not
described above (other than a transfer of a beneficial interest in a Global Note
that does not involve an exchange of such interest for a Certificated Note or a
beneficial interest in another Global Note, which must be effected in accordance
with applicable law and the rules and procedures of DTC, but is not subject to
any procedure required by this Indenture) shall be made only upon receipt by the
Registrar of such opinions of counsel, certificates and/or other information
reasonably required



                                       31

by and satisfactory to it in order to ensure compliance with the Securities Act
or in accordance with SECTION 2.8(D).

                  (d) USE AND REMOVAL OF PRIVATE PLACEMENT LEGENDS. Upon
the transfer, exchange or replacement of Certificated Notes (or beneficial
interests in a Global Note) not bearing a Private Placement Legend, the
Registrar (and the Custodian, in the case of beneficial interests in a Global
Note) shall exchange such Notes (or beneficial interests) for Certificated Notes
(or beneficial interests in a Global Note) that do not bear a Private Placement
Legend. Upon the transfer, exchange or replacement of Certificated Notes (or
beneficial interests in a Global Note) bearing a Private Placement Legend, the
Registrar (and the Custodian, in the case of beneficial interests in a Global
Note) shall deliver only Certificated Notes (or beneficial interests in a Global
Note) that bear a Private Placement Legend unless:

                           (i) such Notes (or beneficial interests) are
                  exchanged in a Registered Exchange Offer;

                           (ii) such Notes (or beneficial interests) are
                  transferred pursuant to a Registration Statement;

                           (iii) such Notes (or beneficial interests) are
                  transferred pursuant to Rule 144 upon delivery to the
                  Registrar of a certificate of the transferor in the form of
                  EXHIBIT E hereto, and an Opinion of Counsel reasonably
                  satisfactory to the Registrar;

                           (iv) such Notes (or beneficial interests) are
                  transferred, replaced or exchanged after the Resale
                  Restriction Termination Date therefor; or

                           (v) in connection with such transfer, exchange or
                  replacement the Registrar shall have received an Opinion of
                  Counsel and other evidence reasonably satisfactory to it to
                  the effect that neither such Private Placement Legend nor the
                  related restrictions on transfer are required in order to
                  maintain compliance with the provisions of the Securities Act.

The Private Placement Legend on any Note shall be removed at the request of the
Holder on or after the Resale Restriction Termination Date therefor. The Holder
of a Global Note may exchange an interest therein for an equivalent interest in
a Global Note not bearing a Private Placement Legend upon transfer of such
interest pursuant to any clauses (i)-(v) above. The Company shall deliver to the
Trustee an Officers' Certificate promptly upon effectiveness, withdrawal or
suspension of any Registration Statement.

                  (e) CONSOLIDATION OF GLOBAL NOTES AND EXCHANGE OF
CERTIFICATED NOTES FOR BENEFICIAL INTEREST IN GLOBAL NOTES. If a Global Note not
bearing a Private Placement Legend (other than a Regulation S Global Note) is
outstanding at the time of a Registered Exchange Offer, any interests in a
Global Note exchanged in such Registered Exchange Offer shall be exchanged for
interests in such outstanding Global Note.

                  (f) RETENTION OF DOCUMENTS. The Registrar shall retain
copies of all letters, notices and other written communications received
pursuant to this Article II. The Company



                                       32
<PAGE>

shall have the right to inspect and make copies of all such letters, notices or
other written communications at any reasonable time upon the giving of
reasonable written notice to the Registrar.

                  (g) EXECUTION, AUTHENTICATION OF NOTES, ETC.

                           (i) Subject to the other provisions of this Section
                  2.8, when Notes are presented to the Registrar or a
                  co-Registrar with a request to register the transfer of such
                  Notes or to exchange such Notes for an equal principal amount
                  of Notes of other authorized denominations, the Registrar or
                  co-Registrar shall register the transfer or make the exchange
                  as requested if its requirements for such transaction are met;
                  PROVIDED that any Notes presented or surrendered for
                  registration of transfer or exchange shall be duly endorsed or
                  accompanied by a written instrument of transfer in form
                  satisfactory to the Registrar or co-Registrar, duly executed
                  by the Holder thereof or his attorney duly authorized in
                  writing. To permit registrations of transfers and exchanges
                  and subject to the other terms and conditions of this Article
                  II, the Company will execute and upon Company Order the
                  Trustee will authenticate Certificated Notes and Global Notes
                  at the Registrar's or co-Registrar's request. In accordance
                  with the Registration Rights Agreement, the Company will
                  execute and upon Company Order the Trustee will authenticate
                  Exchange Notes or Private Exchange Notes, as the case may be,
                  in exchange for Notes.

                           (ii) No service charge shall be made to a Holder for
                  any registration of transfer or exchange, but the Company may
                  require payment of a sum sufficient to cover any transfer tax,
                  assessments, or similar governmental charge payable in
                  connection therewith (other than any such transfer taxes,
                  assessments or similar governmental charges payable upon
                  exchange or transfer pursuant to a Registered Exchange Offer,
                  or Section 4.8, Section 4.14, Section 5.1 or Section 9.5).

                           (iii) The Registrar or co-Registrar shall not be
                  required to register the transfer of or exchange of any Note
                  for a period beginning: (A) 15 days before the mailing of a
                  notice of an offer to repurchase or redeem Notes and ending at
                  the close of business on the day of such mailing or (B) 15
                  days before an Interest Payment Date and ending on such
                  Interest Payment Date.

                           (iv) Prior to the due presentation for registration
                  of transfer of any Note, the Company, the Trustee, the Paying
                  Agent, the Registrar or any co-Registrar may deem and treat
                  the person in whose name a Note is registered as the absolute
                  owner of such Note for the purpose of receiving payment of
                  principal of and interest on such Note and for all other
                  purposes whatsoever, whether or not such Note is overdue, and
                  none of the Company, the Trustee, the Paying Agent, the
                  Registrar or any co-Registrar shall be affected by notice to
                  the contrary.

                           (v) All Notes issued upon any transfer or exchange
                  pursuant to the terms of this Indenture shall evidence the
                  same debt and shall be entitled to the

                                       33
<PAGE>

                  same benefits under this Indenture as the Notes surrendered
                  upon such transfer or exchange.

                  (h) NO OBLIGATION OF THE TRUSTEE.

                           (i) The Trustee shall have no responsibility or
                  obligation to any beneficial owner of interest in a Global
                  Note, a member of, or a participant in, the Depository or
                  other Person with respect to the accuracy of the records of
                  the Depository or its nominee or of any participant or member
                  thereof, with respect to any ownership interest in the Notes
                  or with respect to the delivery to any participant, member,
                  beneficial owner or other Person (other than the Depository)
                  of any notice (including any notice of redemption) or the
                  payment of any amount or delivery of any Notes (or other
                  security or property) under or with respect to such Notes. All
                  notices and communications to be given to the Holders and all
                  payments to be made to Holders in respect of the Notes shall
                  be given or made only to or upon the order of the registered
                  Holders (which shall be the Depository or its nominee in the
                  case of a Global Note). The Trustee may rely and shall be
                  fully protected in relying upon information furnished by the
                  Depository with respect to its members, participants and any
                  beneficial owners.

                           (ii) The Trustee shall have no obligation or duty to
                  monitor, determine or inquire as to compliance with any
                  restrictions on transfer imposed under this Indenture or under
                  applicable law with respect to any transfer of any interest in
                  any Note (including any transfers between or among the
                  Depository participants, members or beneficial owners in any
                  Global Note) other than to require delivery of such
                  certificates and other documentation or evidence as are
                  expressly required by, and to do so if and when expressly
                  required by, the terms of this Indenture, and to examine the
                  same to determine substantial compliance as to form with the
                  express requirements hereof.

                  Section 2.9. MUTILATED, DESTROYED, LOST OR STOLEN NOTES.

                  (a) If a mutilated Note is surrendered to the Registrar
or if the Holder of a Note claims that the Note has been lost, destroyed or
stolen, the Company shall execute and upon Company Order the Trustee shall
authenticate a replacement Note if the requirements of Section 8-405 of the
Uniform Commercial Code are met and the Holder satisfies any other reasonable
requirements of the Trustee. If required by the Trustee or the Company, such
Holder shall furnish an affidavit of loss and indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-Registrar from any loss that any of them
may suffer if a Note is replaced, and, in the absence of notice to the Company
or the Trustee that such Note has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
make available for delivery, in exchange for any such mutilated Note or in lieu
of any such destroyed, lost or stolen Note, a new Note of like tenor and
principal amount, bearing a number not contemporaneously outstanding.

                                       34
<PAGE>

                  (b) Upon the issuance of any new Note under this Section
2.9, the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) in connection
therewith.

                  (c) Every new Note issued pursuant to this Section in
exchange for any mutilated Note, or in lieu of any destroyed, lost or stolen
Note, shall constitute an original additional contractual obligation of the
Company and any other obligor upon the Notes, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all benefits of this Indenture equally and proportionately
with any and all other Notes duly issued hereunder.

                  Section 2.10. TEMPORARY NOTES.

                  Until definitive Notes are ready for delivery, the Company may
execute and upon Company Order the Trustee will authenticate temporary Notes.
Temporary Notes will be substantially in the form of definitive Notes but may
have variations that the Company consider appropriate for temporary Notes.
Without unreasonable delay, the Company will prepare and execute and upon
Company Order the Trustee will authenticate definitive Notes. After the
preparation of definitive Notes, the temporary Notes will be exchangeable for
definitive Notes representing an equal principal amount upon surrender of the
temporary Notes at any office or agency maintained by the Company for that
purpose and such exchange shall be without charge to the Holder. Until so
exchanged, the Holder of temporary Notes shall in all respects be entitled to
the same benefits under this Indenture as a Holder of definitive Notes.

                  Section 2.11. CANCELLATION.

                  The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Notes surrendered to them for registration of transfer, exchange or payment.
The Trustee and no one else shall cancel and return to the Company all Notes
surrendered for registration of transfer, exchange or payment. The Company may
not issue new Notes to replace Notes that have been paid or delivered to the
Trustee for cancellation for any reason other than in connection with a transfer
or exchange.

                  Section 2.12. DEFAULTED INTEREST.

                  When any installment of interest becomes Defaulted Interest
(as defined in the form of Note), such installment shall forthwith cease to be
payable to the Holders in whose names the Notes were registered on the record
date applicable to such installment of interest. Defaulted Interest, and any
interest payable on such Defaulted Interest, may be paid by the Company, at its
election, as provided in clause (i) or (ii) below.

                           (i) The Company may elect to make payment of any
                  Defaulted Interest, and any interest payable on such Defaulted
                  Interest, to the Holders in whose names the Notes are
                  registered at the close of business on a special record date
                  for the payment of such Defaulted Interest (a "SPECIAL RECORD
                  DATE"), which shall be fixed in the following manner. The
                  Company shall notify the Trustee in writing of the amount of
                  Defaulted Interest proposed to be paid on the Notes and

                                       35
<PAGE>

                  the date of the proposed payment, and at the same time the
                  Company shall deposit with the Trustee an amount of money
                  equal to the aggregate amount proposed to be paid in respect
                  of such Defaulted Interest or shall make arrangements
                  satisfactory to the Trustee for such deposit prior to the date
                  of the proposed payment, such money when deposited to be held
                  in trust for the benefit of the Holders entitled to such
                  Defaulted Interest as provided in this clause (i). Thereupon
                  the Trustee shall fix a Special Record Date for the payment of
                  such Defaulted Interest, which shall be not more than 15
                  calendar days and not less than ten calendar days prior to the
                  date of the proposed payment and not less than ten calendar
                  days after the receipt by the Trustee of the notice of the
                  proposed payment. The Trustee shall promptly notify the
                  Company of such Special Record Date and, in the name and at
                  the expense of the Company, shall cause notice of the proposed
                  payment of such Defaulted Interest and the Special Record Date
                  therefor to be sent, first-class mail, postage prepaid, to
                  each Holder at such Holder's address as it appears in the
                  registration books of the Registrar, not less than ten
                  calendar days prior to such Special Record Date. Notice of the
                  proposed payment of such Defaulted Interest and the Special
                  Record Date therefor having been mailed as aforesaid, such
                  Defaulted Interest shall be paid to the Holders in whose names
                  the Notes are registered at the close of business on such
                  Special Record Date and shall no longer be payable pursuant to
                  the following clause (ii); or

                           (ii) The Company may make payment of any Defaulted
                  Interest, and any interest payable on such Defaulted Interest,
                  on the Notes in any other lawful manner not inconsistent with
                  the requirements of any securities exchange on which the Notes
                  may be listed, and upon such notice as may be required by such
                  exchange, if, after notice given by the Company to the Trustee
                  of the proposed payment pursuant to this clause (ii), such
                  manner of payment shall be deemed practicable by the Trustee.

                  Section 2.13. ADDITIONAL AMOUNTS UNDER REGISTRATION RIGHTS
AGREEMENTS.

                  Under certain circumstances, the Company may be obligated to
pay additional interest to Holders, all as and to the extent set forth in the
Registration Rights Agreement. The terms thereof are hereby incorporated herein
by reference and such additional interest is deemed to be interest for purposes
of this Indenture.

                                  ARTICLE III.

                                   REDEMPTION

                  Section 3.1. OPTIONAL REDEMPTION.

                  The Company may redeem the Notes, as a whole or, from time to
time, in part, subject to this Article III and at a redemption price equal to
100% of the outstanding principal amount of the Notes plus a Make-Whole Premium,
plus any accrued and unpaid interest to the



                                       36
<PAGE>

Redemption Date, if any (the "REDEMPTION Price"). The Company shall evidence its
election to redeem any Notes pursuant to this Section 3.1 by a Board Resolution.

                  Section 3.2. NOTICES TO TRUSTEE.

                  If the Company elects to redeem Notes, either in whole or in
part, pursuant to Section 3.1 hereof, the Company shall notify the Trustee in
writing, at least 15 days prior to the date upon which notice of redemption is
to be given to Holders pursuant to Section 3.4 hereof, of the Redemption Date,
the principal amount of Notes to be redeemed and the Redemption Price, and
deliver to the Trustee an Officers' Certificate stating that such redemption
will comply with the conditions contained in this Article III, as appropriate.

                  Section 3.3. SELECTION BY TRUSTEE OF NOTES TO BE REDEEMED.

                  In the event that fewer than all of the Notes are to be
redeemed, the Trustee shall select the Notes to be redeemed, if the Notes are
listed on a national securities exchange, in accordance with the rules of such
exchange or, if the Notes are not so listed, by lot, PRO RATA or by such other
method as it shall deem fair and reasonable. The Trustee shall promptly notify
the Company of the Notes selected for redemption and, in the case of any Notes
selected for partial redemption, the principal amount thereof to be redeemed.
The Trustee may select for redemption portions of the principal of the Notes
that have denominations larger than $1,000. Notes and portions thereof that the
Trustee selects shall be redeemed in amounts of $1,000 or whole multiples of
$1,000. For all purposes of this Indenture unless the context otherwise
requires, provisions of this Indenture that apply to Notes called for redemption
also apply to portions of Notes called for redemption.

                  Section 3.4. NOTICE OF REDEMPTION.

                  (a) At least 30 days, but no more than 60 days, before a
Redemption Date, the Company shall mail, or cause to be mailed, a notice of
redemption by first-class mail to each Holder of Notes to be redeemed at his or
her last address as the same appears on the registry books maintained by the
Registrar pursuant to Section 2.3 hereof.

                  (b) The notice shall identify the Notes to be redeemed
(including the CUSIP numbers thereof) and shall state:

                           (i) the Redemption Date;

                           (ii) the Redemption Price;

                           (iii) if any Note is being redeemed in part, the
                  portion of the principal amount of such Note to be redeemed
                  and that, after the Redemption Date and upon surrender of such
                  Note, a new Note or Notes in principal amount equal to the

                           (v) that Notes called for redemption must be
                  surrendered to the Paying Agent to collect the Redemption
                  Price;

                           (vi) that unless the Company defaults in making the
                  redemption payment, interest will cease to accrue on Notes or
                  portions thereof called for redemption on and after the
                  Redemption Date; and

                           (vii) the aggregate principal amount of Notes that
                  are being redeemed.

                  (c) At the request of the Company, the Trustee shall give
the notice of redemption in the name of the Company and at the sole expense of
the Company.

                  Section 3.5. EFFECT OF NOTICE OF REDEMPTION.

                  Once the notice of redemption described in Section 3.4 hereof
is mailed, Notes called for redemption become due and payable on the Redemption
Date and at the Redemption Price plus interest accrued to the Redemption Date.
Upon surrender to the Paying Agent, such Notes shall be paid at the Redemption
Price plus interest accrued to the Redemption Date; PROVIDED, that if the
Redemption Date is after a regular interest payment record date and on or prior
to the Interest Payment Date, any accrued interest shall be payable to the
Holder of the redeemed Notes registered on the relevant record date, and
PROVIDED, FURTHER, that if a Redemption Date is a Legal Holiday, payment shall
be made on the next succeeding Business Day and no interest shall accrue for the
period from such Redemption Date to such succeeding Business Day. Failure to
give notice or any defect in the notice to any Holder shall not affect the
validity of the notice to any other Holder.

                  Section 3.6. DEPOSIT OF REDEMPTION PRICE.

                  (a) On or prior to 10:00 A.M., New York City time, on
each Redemption Date, the Company shall deposit with the Paying Agent in
immediately available funds money sufficient to pay the Redemption Price of, and
accrued and unpaid interest to the Redemption Date on, all Notes to be redeemed
on that date other than Notes or portions thereof called for redemption on that
date which have been delivered by the Company to the Trustee for cancellation.

                  (b) On and after any Redemption Date, if money sufficient
to pay the Redemption Price of, and accrued and unpaid interest to the
Redemption Date on, the Notes called for redemption shall have been made
available in accordance with the preceding paragraph and payment thereof is not
prohibited pursuant to the terms of this Indenture, then the Notes called for
redemption will cease to accrue interest and the only right of the Holders of
such Notes will be to receive payment of the Redemption Price of and, subject to
the first proviso in Section 3.5 hereof, accrued interest to the Redemption Date
on, such Notes to the Redemption Date. If any Note called for redemption shall
not be so paid, interest will be paid, from the Redemption Date until such
redemption payment is made, on the unpaid Redemption Price of the Note and any
interest not paid on such unpaid amount at the rate and in the manner provided
in the Notes.

shall authenticate for a Holder a new Note equal in principal amount to the
unredeemed portion of the Note surrendered.

Redemption Price or Change of Control Purchase Price of, or accrued interest on,

The Company will also, in any event, (i) within 15 days of each Required Filing
Date (A) transmit by mail to all Holders, as their names and addresses appear in
the Security register maintained by the Registrar, without cost to such Holders
copies of those annual reports, quarterly reports and other documents which the

                  (b) The Company will, upon request, provide to any Holder
of Notes or any prospective transferee of any such Holder any information
concerning the Company (including financial statements) necessary in order to
permit such Holder to sell or transfer Notes in compliance with Rule 144A under
the Securities Act, if applicable; PROVIDED, HOWEVER, that the Company shall not
be required to furnish such information in connection with any request made on

so) that it will not at any time insist upon, or plead (as a defense or
otherwise) or in any manner whatsoever claim or take the benefit or advantage
of, any stay or extension law or any usury law or other law which would prohibit
or forgive the Company from paying all or any portion of the principal,
Redemption Price or Change of Control Purchase Price of, or accrued interest on,
the Notes as contemplated herein, wherever enacted, now or at any time hereafter
in force, or which may affect the covenants or the performance of this
Indenture. The Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law, and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

review of the activities of the Company and its Subsidiaries during such fiscal
year has been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture, and further stating, as to each such Officer
signing such certificate, that to the best of his or her knowledge the Company
has kept, observed, performed and fulfilled each and every covenant contained in
this Indenture and is not in default in the performance or observance of any of
the terms, provisions and conditions hereof (or, if a Default or Event of
Default shall have occurred, describing all Defaults or Events of Default of
which he or she may have knowledge and what action the Company is taking or
proposes to take with respect thereto) and that to the best of his or her
knowledge no event has occurred and remains in existence by reason of which

Purchase Price of, and accrued interest on, the Notes are prohibited or, if such
event has occurred, a description of the event and what action each of the
Company is taking or proposes to take with respect thereto.

                  (b) So long as (and to the extent) not contrary to the
then current recommendations of the American Institute of Certified Public
Accountants, the year-end financial statements delivered pursuant to Section 4.2
above shall be accompanied by a written statement of the Company's independent
public accountants (who shall be a firm of established national reputation) that
in making the examination necessary for certification of such financial
statements nothing has come to their attention which would lead them to believe
that the Company has violated any provisions of this Article IV or Article V of
this Indenture or, if any such violation has occurred, specifying the nature and
period of existence thereof, it being understood that such accountants shall not
be liable directly or indirectly for any failure to obtain knowledge of any such
violation.

                  (a) The Company will not, and will not permit any of the
Restricted Subsidiaries to, consummate an Asset Sale unless:

                           (i) the Company or the applicable Restricted
                  Subsidiary, as the case may be, receives consideration at the
                  time of the Asset Sale at least equal to the fair market value
                  of the assets sold or otherwise disposed of as determined in
                  good faith by the Board of Directors of the Company;

                           (ii) at least 75% of the consideration received by
                  the Company or the Restricted Subsidiary, as the case may be,
                  from the Asset Sale shall be in the form of cash or Cash
                  Equivalents and is received at the time of such Asset Sale;
                  and

                           (iii) upon the consummation of an Asset Sale, the
                  Company may apply, or cause such Restricted Subsidiary to
                  apply, the Net Cash Proceeds relating to such Asset Sale
                  within 360 days of receipt thereof either:

                                    (A) to repay any Indebtedness of the Company
                  to the extent secured by a Lien pursuant to clause (i), (ii),
                  (iii), (iv), (v) or (viii) of paragraph (b) of Section 4.11
                  hereof and effect a permanent reduction in the availability in
                  respect of the Indebtedness (without refinancing the
                  Indebtedness);

                                    (B) to repay any Indebtedness of a Wholly
                  Owned Restricted Subsidiary owed to any Person other than the
                  Company or any of its Affiliates and effect a permanent
                  reduction in any availability in respect of the Indebtedness
                  (without refinancing the Indebtedness);

                                    (C) to acquire Replacement Assets; or

                                    (D) a combination of prepayment and

borrowed money of the Company or any Restricted Subsidiary other than
Disqualified Capital Stock or Indebtedness subordinated in right



                                       44

of payment to the Notes shall be deemed to be cash applied in accordance
with this covenant. The receipt by the Company or the applicable Restricted
Subsidiary of marketable securities of a company subject to and then current in
its obligations as a reporting company under Section 13 or 15 under the Exchange
Act, which are resold for cash or Cash Equivalents by the Company or the
Restricted Subsidiary within 120 days of the relevant Asset Sale and applied in
accordance with this covenant, shall be deemed to be cash received pursuant to
clause (ii) of this paragraph (a).

                  (b) On the 361st day after an Asset Sale or such earlier
date, if any, as the Board of Directors of the Company or of such Restricted
Subsidiary determines not to apply the Net Cash Proceeds relating to the Asset
Sale as set forth in clause (iii) of paragraph (a) of this Section 4.8 (each, a
"NET PROCEEDS OFFER TRIGGER DATE"), the aggregate amount of Net Cash Proceeds
that have not been applied on or before the Net Proceeds Offer Trigger Date as
permitted in that clause (iii) (a "NET PROCEEDS OFFER AMOUNT") shall be applied
by the Company to make an offer to purchase (the "NET PROCEEDS OFFER") on a date
(the "NET PROCEEDS OFFER PAYMENT DATE") not less than 30 nor more than 60 days
following the Net Proceeds Offer Trigger Date, from all Holders on a PRO RATA
basis, that principal amount of Notes equal to the Net Proceeds Offer Amount at
a price equal to 100% of the principal amount of the Notes to be purchased, plus
accrued and unpaid interest, if any, thereon to the date of purchase; PROVIDED
that the Company may make a concurrent offer to repurchase on a PRO RATA basis
Indebtedness of a Wholly Owned Restricted Subsidiary or Indebtedness of the
Company ranking PARI PASSU with the Notes.

                  (c) If at any time any non-cash consideration received by
the Company or any Restricted Subsidiary, as the case may be, in connection with
any Asset Sale is converted into or sold or otherwise disposed of for cash
(other than interest received with respect to any such non-cash consideration)
or Cash Equivalents, then such conversion or disposition shall be deemed to
constitute an Asset Sale hereunder and the Net Cash Proceeds thereof shall be
applied in accordance with this Section 4.8. Pending application in accordance
with this Section 4.8, Net Cash Proceeds may be used to repay revolving credit
borrowings without reducing commitments thereunder.

                  (d) The Company may defer the Net Proceeds Offer until
there is an aggregate unutilized Net Proceeds Offer Amount equal to or in excess
of $5.0 million resulting from one or more Asset Sales or deemed Asset Sales (at
which time, the entire unutilized Net Proceeds Offer Amount, and not just the
amount in excess of $5.0 million, shall be applied as required pursuant to this
Section 4.8).

                  (e) In the event of the transfer of substantially all
(but not all) of the property and assets of the Company and the Restricted
Subsidiaries as an entirety to a Person in a transaction permitted under Section
5.1 hereof, the successor corporation shall be deemed to have sold the
properties and assets of the Company and the Restricted Subsidiaries not
transferred for purposes of this Section 4.8 and shall comply with the
provisions of this Section 4.8 with respect to such deemed sale as if it were an
Asset Sale. In addition, the fair market value (as determined in good faith by
the Board of Directors of the Company) of such properties and assets of the
Company or the Restricted Subsidiaries deemed to be sold shall be deemed to be
Net Cash Proceeds for purposes of this Section 4.8.

                  (f) Each Net Proceeds Offer will be mailed to the record
Holders as shown on the register of Holders within 30 days following the Net
Proceeds Offer Trigger Date, with a copy to the Trustee, and shall comply with
the procedures set forth in this Indenture. Upon receiving notice of the Net
Proceeds Offer, Holders may elect to tender their Notes in whole or in part in
integral multiples of $1,000 in exchange for cash. To the extent Holders
properly tender Notes in an amount exceeding the Net Proceeds Offer Amount,
Notes of tendering Holders will be purchased on a PRO RATA basis based on the
principal amount of Notes (and other Indebtedness for which a concurrent offer
is being made as permitted by this Section 4.8) tendered. A Net Proceeds Offer
shall remain open for a period of 20 business days or such longer period as may
be required by law.

                  (g) The Company will comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the repurchase of Notes pursuant to a Net Proceeds Offer. To the extent
that the provisions of any securities laws or regulations conflict with this
Section 4.8, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this
Section 4.8 by virtue thereof.

                  Section 4.9. LIMITATION ON DISTRIBUTIONS AND OTHER
RESTRICTIONS AFFECTING SUBSIDIARIES.

                  The Company will not, and will not cause or permit any of the
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
permit to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary to:

                  (a) pay dividends or make any other distributions on or in
respect of its Capital Stock;

                  (b) make loans or advances or pay any Indebtedness or other
obligation owed to the Company or any other Restricted Subsidiary; or

any other Restricted Subsidiary,

except for such encumbrances or restrictions existing under or by reasons of:

                           (i) applicable law or regulation or NYSE regulations;

                           (ii) this Indenture;

                  Restricted Subsidiary;

                  which encumbrance or restriction is not applicable to any
                  Person, or the properties or assets of any Person, other than
                  the Person or the properties or assets of the Person so
                  acquired;

                                       46
<PAGE>

                           (v) agreements existing on the Issue Date to the
                  extent and in the manner such agreements are in effect on the
                  Issue Date;

                           (vi) any other agreement entered into after the Issue
                  Date that contains encumbrances and restrictions that are not
                  materially more restrictive with respect to any Restricted
                  Subsidiary than those in effect with respect to such
                  Restricted Subsidiary pursuant to agreements as in effect on
                  the Issue Date so long as any such restrictions expressly
                  permit scheduled payments on the Notes;

                           (vii) customary restrictions on the transfer of any
                  property or assets arising under a security agreement
                  governing a Lien permitted under this Indenture; and

                           (viii) any agreement governing Refinancing
                  Indebtedness incurred to Refinance the Indebtedness issued,
                  assumed or incurred pursuant to an agreement referred to in
                  clause (ii), (iv) or (v) above; PROVIDED, HOWEVER, that the
                  provisions relating to such encumbrance or restriction
                  contained in any such Refinancing Indebtedness are not
                  materially more restrictive than the provisions relating to
                  such encumbrance or restriction contained in agreements
                  referred to in such clause (ii), (iv) or (v) and expressly
                  permit dividends and other distributions for scheduled
                  payments on the Notes.

that are not materially less favorable than those that would have reasonably
been expected in a comparable transaction at such time on an arm's-length basis
from a Person that is not an Affiliate of the Company or such Restricted
Subsidiary. Prior to the consummation by the Company or any Restricted
Subsidiary of any Affiliate Transactions (or series of related Affiliate

                  committee thereof);

                           (ii) reasonable fees and compensation paid to
                  directors, and reasonable indemnity provided on behalf of
                  officers, directors, employees, consultants or agents, of the
                  Company or any Restricted Subsidiary as determined in good
                  faith by the Company's Board of Directors or senior

                  Company and any Restricted Subsidiaries or exclusively between
                  or among Restricted Subsidiaries, provided such transactions

                           (iv) Restricted Payments permitted to be made
pursuant to Section 4.7 hereof.

                  Section 4.13. LIMITATION ON DESIGNATIONS OF UNRESTRICTED
SUBSIDIARIES.

                  (a) The Company may designate any Subsidiary of the
Company, other than LaBranche or a Person holding Capital Stock of LaBranche, as
an "UNRESTRICTED SUBSIDIARY" under this Indenture (a "DESIGNATION") only if:

                           (i) no Default shall have occurred and be
                  continuing at the time of or after giving effect to such
                  Designation; and

                           (ii) the Company would be permitted under this
                  Indenture to make an Investment at the time of Designation
                  assuming the effectiveness of the Designation in an amount
                  (the "DESIGNATION AMOUNT") equal to the sum of:

                                    (A) the fair market value of the Capital
                  Stock of the Subsidiary owned by the Company and/or any of the
                  Restricted Subsidiaries on such date and

                                    (B) the aggregate amount of Indebtedness of
                  the Subsidiary owed to the Company and the Restricted
                  Subsidiaries on that date; and

                           (iii) the Company would be permitted to incur $1.00
                  of additional Indebtedness (other than Permitted Indebtedness)
                  pursuant to the covenant described under Section 4.6 hereof at
                  the time of Designation assuming the effectiveness of the
                  Designation.

                  (b) In the event of any such Designation, the Company
shall be deemed to have made an Investment constituting a Restricted Payment in
the Designation Amount pursuant to Section 4.7 hereof for all purposes of this
Indenture. Furthermore, the Company shall not, and shall not permit any
Restricted Subsidiary to, at any time:

                           (i) provide direct or indirect credit support for or
                  a guarantee of any Indebtedness of any Unrestricted Subsidiary
                  (including any undertaking, agreement or instrument evidencing
                  such Indebtedness),

                           (ii) be directly or indirectly liable for
                  any Indebtedness of any Unrestricted Subsidiary or

                           (iii) be directly or indirectly liable for any
                  Indebtedness that provides that the holder thereof may (upon
                  notice, lapse of time or both) declare a default thereon or
                  cause the payment thereof to be accelerated or payable prior
                  to its final scheduled maturity upon the occurrence of a
                  default with respect to any Indebtedness of any Unrestricted
                  Subsidiary (including any right to take enforcement action
                  against the Unrestricted Subsidiary).

                  (c) The Company may revoke any Designation of a
Subsidiary as an Unrestricted Subsidiary ("REVOCATION"), whereupon such
Subsidiary shall then constitute a Restricted Subsidiary, if:

                           (i) no Default shall have occurred and be
                  continuing at the time and after giving effect to such
                  Revocation; and

                           (ii) all Liens and Indebtedness of such Unrestricted
                  Subsidiaries outstanding immediately following such Revocation
                  would, if incurred at such time, have been permitted to be
                  incurred for all purposes of this Indenture.

                  (d) All Designations and Revocations must be evidenced by
an Officers' Certificate of the Company delivered to the Trustee certifying
compliance with the foregoing provisions.

                  Section 4.14. CHANGE OF CONTROL.

                  (a) Upon the occurrence of a Change of Control, the
Company will make a Change of Control Offer to Purchase all of the outstanding
Notes at the Change of Control Purchase Price.

For purposes of the foregoing, a Change of Control Offer to Purchase shall be
deemed to have been made if:

                           (i) within 30 days following the date of the
consummation of a transaction or series of transactions that constitutes a
Change of Control, the Company commences a Change of Control Offer to Purchase
for all outstanding Notes at the Change of Control Purchase Price (provided that
the running of such 30-day period shall be suspended, for up to a maximum of 30
days, during any period when the commencement of such Change of Control Offer to
Purchase is delayed or suspended by reason of any court's or governmental
authority's review of or ruling on any materials being employed by the Company
to effect such Change of Control Offer to Purchase, so long as the Company has
used and continues to use its best efforts to make and conclude such Change of
Control Offer to Purchase promptly); and

                                       51
<PAGE>

                           (ii) all Notes properly tendered pursuant to the
Change of Control Offer to Purchase are purchased on the terms of such Change of
Control Offer to Purchase.

                  (b) The Company will not be required to make a Change of
Control Offer to Purchase upon a Change of Control if a third party makes a
Change of Control Offer to Purchase contemporaneously with or upon a Change of
Control in the manner, at the times and otherwise in compliance with the
requirements of this Indenture and purchases all Notes validly tendered and not
withdrawn under its Change of Control Offer to Purchase.

                  (c) On the Change of Control Purchase Date, the Company
shall, to the extent lawful, (i) accept for payment Notes or portions thereof or
beneficial interests under a Global Note properly tendered pursuant to the Offer
to Purchase, (ii) deposit with the Paying Agent (by no later than 11:00 a.m. on
such date) money sufficient to pay the Change of Control Purchase Price of all
Notes or portions thereof or beneficial interests so tendered and (iii) deliver
or cause to be delivered to the Trustee Notes so accepted together with an
Officers' Certificate stating the Notes or portions thereof tendered to the
Company. The Paying Agent shall promptly (1) mail to each holder of Notes so
accepted and (2) remit to the Depository for crediting to the respective
accounts of the Holders under a Global Note of beneficial interest so accepted,
payment in an amount equal to the purchase price for such Notes (which payment
shall, in the case of the Holders of beneficial interests in a Global Note, be
through the facilities of the Depository), and the Company shall execute and
issue, and the Trustee shall promptly authenticate and mail to such holder, a
new Note equal in principal amount to any untendered portion of the Notes
surrendered and shall issue a Global Note equal in principal amount to any
untendered portion of beneficial interest so surrendered; PROVIDED that each
such new Note shall be issued in an original principal amount in denominations
of $1,000 and integral multiples thereof.

                  (d) If the Company or any Subsidiary thereof has issued
any outstanding Indebtedness that is subordinated in right of payment to the
Notes, and the Company or such Subsidiary is required to make an offer to
purchase upon a Change of Control or to make a distribution with respect to such
subordinated Indebtedness or Preferred Stock in the event of a Change of
Control, the Company shall not consummate any such offer or distribution with
respect to such subordinated Indebtedness or Preferred Stock until such time as
the Company shall have paid the Change of Control Purchase Price in full to the
holders of Notes that have accepted the Company's Change of Control Offer to
Purchase and shall otherwise have consummated the Change of Control Offer to
Purchase made to holders of the Notes. The Company will not issue Indebtedness
that is subordinated in right of payment to the Notes or Preferred Stock with
change of control provisions requiring the payment of such Indebtedness or
Preferred Stock prior to making and consummating an offer to purchase the Notes
in the event of a Change of Control under this Indenture.

                  (e) The Company will comply, to the extent applicable,
with the requirements of Rule l4e-1 under the Exchange Act and any other
securities laws and regulations to the extent such laws and regulations are
applicable in connection with any repurchase of the Notes as described above. To
the extent that the provisions of any securities laws or regulations conflict
with any repurchase of the Notes as described above, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this Section 4.14 by virtue thereof.

                  Section 4.15. MAINTENANCE OF OFFICE OR AGENCY.

                  The Company shall maintain in New York, New York an office or
agency where Notes may be surrendered for registration of transfer or exchange
or for presentation for payment and where notices and demands to or upon the
Company in respect of the Notes and this Indenture may be served. The Company
shall give prompt written notice to the Trustee of the location, and any change
in the location, of such office or agency. If at any time the Company shall fail
to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the address of the Trustee as set forth in
Section 10.2. The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations, PROVIDED,
HOWEVER, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in New York, New York
for such purposes. The Company shall give prompt written notice to the Trustee
of such designation or rescission and of any change in the location of any such
other office or agency. The Company hereby initially designates the Corporate
Trust Office of the Trustee as such office of the Company.

                  Section 4.16. MAINTENANCE OF PROPERTIES AND INSURANCE.

or useful to the conduct of its business or the business of any of its
Restricted Subsidiaries to be maintained and kept in good condition, repair and
working order (reasonable wear and tear excepted) and supplied with all
equipment deemed necessary in the good faith judgment of the Officers of the
Company and shall cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof; PROVIDED, HOWEVER, that
nothing in this Section 4.16 shall prevent the Company or any Restricted
Subsidiary from discontinuing the operation or maintenance of any of such
properties, or disposing of any of them, if such discontinuance or disposal is
in the good faith judgment of the Board of Directors of the Company or the
Restricted Subsidiary concerned, as the case may be, desirable in the conduct of
the business of the Company or such Restricted Subsidiary, as the case may be,
and is not adverse in any material respect to the Holders.

                  (b) The Company shall provide or cause to be provided, for
itself and each of its Restricted Subsidiaries, insurance (including
appropriate self-insurance) against loss or damage of the kinds that are
adequate and appropriate for the conduct of the business of the Company and
such Restricted Subsidiaries in a prudent manner, with reputable insurers or
with the government of the United States of America or an agency or
instrumentality thereof, in such amounts, with such deductibles, and by such
methods as shall be customary, in the good faith judgment of the Company, for
corporations similarly situated in the industry.

                  Agreement) on any Notes when the same becomes due and payable
                  and the default continues for a period of 30 days;

                           (ii) the failure to pay the principal on any Notes,

                           (iii) a default in the observance or performance of
                  the covenant described under Section 5.1 hereof;

                           (iv) a default in the observance or performance of
                  any other covenant or agreement contained in this Indenture,

                  the Company receives written notice specifying the default
                  from the Trustee or the Holders of at least 25% of the
                  outstanding principal amount of the Notes;

                           (v) a default under any mortgage, indenture or

                                    (A) is caused by failure to pay principal of
                  such Indebtedness after any applicable grace period provided
                  in such Indebtedness on the date of such default (a "PAYMENT
                  DEFAULT"), or

                                    (B) results in the acceleration of such
                  Indebtedness prior to its express maturity,

                  and the aggregate principal amount of any Indebtedness to
                  which clause (A) or (B) applies at the relevant time, exceeds
                  $5.0 million;

                           (vi) one or more judgments in an aggregate amount in
                  excess of $5.0 million shall have been rendered against the
                  Company or any of the Restricted Subsidiaries and such
                  judgements remain undischarged, unpaid or unstayed for a
                  period of 45 calendar days after such judgment or judgments

                           (vii) the entry by a court having jurisdiction in the
                  premises of (A) a decree or order for relief in respect of the
                  Company or any Significant Subsidiary of the Company in an

The foregoing will constitute Events of Default whatever the reason for any such
Event of Default and whether it is voluntary or involuntary or is effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body.

                  (b) The Company shall deliver to the Trustee upon
becoming aware of any Default or Event of Default written notice in the form of
an Officers' Certificate of any Default



                                       57
<PAGE>

or Event of Default that has occurred and, if applicable, the Company shall also
describe such Default or Event of Default and the status thereof (provided that
the Company shall provide such certification at least annually whether or not it
knows of any Default or Event of Default).

                  Section 6.2.      ACCELERATION.

                  (a) If an Event of Default (other than an Event of
Default specified in clauses (vii), (viii) or (ix) of Section 6.1) shall occur
and be continuing, the Trustee or the Holders of at least 25% in principal
amount of outstanding Notes may declare the principal of, and accrued interest
on, all the Notes to be due and payable by notice in writing to the Company and
(if given by the Holders) the Trustee, specifying the respective Events of
Default and that it is a "notice of acceleration," and the same shall become
immediately due and payable. If an Event of Default specified in clauses (vii),
(viii) or (ix) of Section 6.1 occurs and is continuing, then all unpaid
principal of, and accrued and unpaid interest on, all of the outstanding Notes
shall become and be immediately due and payable without any declaration or other
act on the part of the Trustee or any Holder.

                  (b) At any time after a declaration of acceleration with
respect to the Notes as described in the preceding paragraph, the Holders of a
majority in principal amount of the then outstanding Notes may rescind and
cancel such declaration and its consequences:

                           (i) if the rescission would not conflict
                  with any judgment or decree;

                           (ii) if all existing Events of Default have been
                  cured or waived except nonpayment of principal or interest
                  that has become due solely because of the acceleration;

                           (iii) to the extent payment of such interest is
                  lawful, if interest on overdue installments of interest and
                  overdue principal, which has become due otherwise than by such
                  declaration of acceleration, has been paid;

                           (iv) if the Company has paid the Trustee its
                  reasonable compensation and reimbursed the Trustee for its
                  expenses, disbursements and advances; and

                           (v) in the event of the cure or waiver of an Event of
                  Default of the type described in clauses (vii), (viii) or (ix)
                  of Section 6.1, the Trustee shall have received an officers'
                  certificate and an opinion of counsel that such Event of
                  Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right
consequent thereto.

                  (c) The Holders of a majority in principal amount of the
then outstanding Notes may waive any existing Default or Event of Default under
this Indenture, and its consequences, except a default in the payment of the
principal of or interest on any Notes.

                  (d) Holders of the Notes may not enforce this Indenture
or the Notes except as provided in this Indenture and under the TIA. Subject to
the provisions of this Indenture relating to the duties of the Trustee, the
Trustee is under no obligation to exercise any of its rights or



                                       58
<PAGE>

powers under this Indenture at the request, order or direction of any of the
Holders, unless such Holders have offered to the Trustee reasonable indemnity.
Subject to all provisions of this Indenture and applicable law, the Holders of a
majority in aggregate principal amount of the then outstanding Notes have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee.

                  Section 6.3. OTHER REMEDIES.

                  If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy by proceeding at law or in equity to collect the
payment of principal, Redemption Price or Change of Control Purchase Price of,
and accrued interest on, the Notes or to enforce the performance of any
provision of the Notes or this Indenture and may take any necessary action
requested of it as Trustee to settle, compromise, adjust or otherwise conclude
any proceedings to which it is a party. The Trustee may maintain a proceeding
even if it does not possess any of the Notes or does not produce any of them in
the proceeding. A delay or omission by the Trustee or any Holder in exercising
any right or remedy accruing upon an Event of Default shall not impair the right
or remedy or constitute a waiver of or acquiescence in the Event of Default. No
remedy is exclusive of any other remedy. All available remedies are cumulative
to the extent permitted by law.

                  Section 6.4. WAIVER OF PAST DEFAULTS AND EVENTS OF DEFAULT.

                  Subject to Sections 6.2, 6.7 and 8.2 hereof, the Holders of
not less than a majority in aggregate principal amount of the outstanding Notes
may on behalf of the Holders of all the Notes waive any past Default under this
Indenture and its consequences, except a Default (1) in any payment in respect
of the principal, Redemption Price or Change of Control Purchase Price of, and
accrued interest on, any Notes (including any Note which is required to have
been purchased pursuant to a Change of Control Offer to Purchase which has been
made by the Company), or (2) in respect of a covenant or provision hereof which
under this Indenture cannot be modified or amended without the consent of the
Holder of each outstanding Note affected. Upon any such waiver, such Default
shall cease to exist, and any Event of Default arising therefrom shall be deemed
to have been cured for every purpose of this Indenture, but no such waiver shall
extend to any subsequent or other Default or Event of Default or impair any
right consequent thereto.

                  Section 6.5. CONTROL BY MAJORITY.

                  The Holders of a majority in principal amount of the Notes
then outstanding may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee by this Indenture. The Trustee, however, may
refuse to follow any direction that conflicts with law or this Indenture or that
the Trustee determines may be unduly prejudicial to the rights of another Holder
not taking part in such direction, and the Trustee shall have the right to
decline to follow any such direction if the Trustee, being advised by counsel,
determines that the action so directed may not lawfully be taken or if the
Trustee in good faith shall, by a Trust Officer, determine that the proceedings
so directed, or the exercise of such trust or power, may involve it in personal
liability; PROVIDED that



                                       59
<PAGE>

the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

                  Section 6.6. LIMITATION ON SUITS.

                  Subject to Section 6.7 hereof, no Holder of any Note will have
any right to institute any proceeding with respect to this Indenture or for any
remedy thereunder, unless such Holder shall have previously given to the Trustee
written notice of a continuing Event of Default and unless the Holders of at
least 25% in aggregate principal amount of the outstanding Notes shall have made
written request, and offered reasonable indemnity, to the Trustee to institute
such proceeding as Trustee, and the Trustee shall not have received from the
Holders of a majority in aggregate principal amount of the outstanding Notes a
direction inconsistent with such request and the Trustee shall have failed to
institute such proceeding within 60 calendar days. A Holder may not use this
Indenture to prejudice the rights of another Holder or to obtain a preference or
priority over another Holder.

                  Section 6.7. RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder of a Note to receive payment of principal, Redemption Price
or Change of Control Purchase Price of, and accrued interest on, the Note on or
after the respective due dates expressed in the Note, or to bring suit for the
enforcement of any such payment on or after such respective dates, is absolute
and unconditional and shall not be impaired or affected without the consent of
the Holder.

                  Section 6.8. COLLECTION SUIT BY TRUSTEE.

                  If an Event of Default in payment of principal, Redemption
Price or Change of Control Purchase Price of, or accrued interest on, the Notes
specified in Section 6.1(a)(i) or (ii) hereof occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against the Company (or any other obligor on the Notes) for the whole amount of
unpaid principal, Redemption Price or Change of Control Purchase Price of, and
accrued interest on, the Notes remaining unpaid, together with interest on
overdue principal, Redemption Price or Change of Control Purchase Price, and, to
the extent that payment of such interest is lawful, interest on overdue
installments of interest, in each case at the rate then borne by the Notes, and
such further amounts as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, including all sums due and
owing to the Trustee pursuant to Section 7.7.

                  Section 6.9. TRUSTEE MAY FILE PROOFS OF CLAIM.

                  The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relative to the Company (or any
other obligor upon the Notes), their creditors or their property and shall be
entitled and empowered to collect and receive any monies or other property
payable or deliverable on any such claims and to distribute the same after
deduction of its reasonable charges and expenses to



                                       60
<PAGE>

the extent that any such charges and expenses are not paid out of the estate in
any such proceedings and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.7 hereof.
Nothing herein contained shall be deemed to authorize the Trustee to authorize
or consent to or accept or adopt on behalf of any Holder any plan or
reorganization, arrangement, adjustment or composition affecting the Notes or
the rights of any Holder thereof, or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceedings.

                  Section 6.10. PRIORITIES.

                  (a) If the Trustee collects any money pursuant to this
Article VI, it shall pay out the money in the following order:

                                    FIRST: to the Trustee for amounts due under
                  Section 7.7 hereof;

                                    SECOND: to Holders for amounts due and
                  unpaid on the Notes for principal, Redemption Price or Change
                  of Control Purchase Price of, and accrued interest (which
                  shall include any Damage Amount as provided in the
                  Registration Rights Agreement) as to each, ratably, without
                  preference or priority of any kind, according to the amounts
                  due and payable on the Notes; and

                                    THIRD: to the Company.

                  (b) The Trustee may fix a record date and payment date
for any payment to Holders pursuant to this Section 6.10.

                  Section 6.11. UNDERTAKING FOR COSTS.

                  In any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by
any party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 6.7 hereof or a suit by Holders of more than 10% in
principal amount of the Notes then outstanding.

                  Section 6.12. RESTORATION OF RIGHTS AND REMEDIES.

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all



                                       61
<PAGE>

rights and remedies of the Trustee and the Holders shall continue as though no
such proceeding had been instituted.

                                  ARTICLE VII.

                                     TRUSTEE

                  Section 7.1. DUTIES OF TRUSTEE.

                  (a) If an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture and use the same degree of care and skill in their exercise
as a prudent man would exercise or use under the same circumstances in the
conduct of his own affairs.

                  (b) Except during the continuance of an Event of Default:

                           (i) The Trustee need perform only those duties that
                  are specifically set forth in this Indenture and no others and
                  no implied covenants or obligations shall be read into this
                  Indenture against the Trustee.

                           (ii) In the absence of bad faith on its part, the
                  Trustee may conclusively rely, as to the truth of the
                  statements and the correctness of the opinions expressed
                  therein, upon certificates or opinions furnished to the
                  Trustee and conforming to the requirements of this Indenture
                  but, in the case of any such certificates or opinions which by
                  any provision hereof are specifically required to be furnished
                  to the Trustee, the Trustee shall be under a duty to examine
                  the same to determine whether or not they conform to the
                  requirements of this Indenture (but need not confirm or
                  investigate the accuracy of mathematical calculations or other
                  facts stated therein).

                  (c) The Trustee may not be relieved from liability for
its own negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

                           (i) This paragraph does not limit the effect of
paragraph (b) of this Section 7.1.

                           (ii) The Trustee shall not be liable for any error of
                  judgment made in good faith by a Trust Officer, unless it is
                  proved that the Trustee was negligent in ascertaining the
                  pertinent facts.

                           (iii) The Trustee shall not be liable with respect to
                  any action it takes or omits to take in good faith in
                  accordance with a direction received by it pursuant to
                  Sections 6.2 and 6.5 hereof.

                           (iv) No provision of this Indenture shall require the
                  Trustee to expend or risk its own funds or otherwise incur any
                  financial liability in the performance of any of its rights or
                  powers if it shall have reasonable grounds for believing that

                                       62
<PAGE>

                  repayment of such funds or adequate indemnity satisfactory to
                  it against such risk or liability is not reasonably assured to
                  it.

                  (d) Whether or not therein expressly so provided,
paragraphs (a), (b), (c), (e), (f) and (g) of this Section 7.1 shall govern
every provision of this Indenture that in any way relates to the Trustee.

                  (e) The Trustee may refuse to perform any duty or
exercise any right or power unless it receives indemnity reasonably satisfactory
to it against any loss, liability, expense or fee.

                  (f) The Trustee shall not be liable for interest on any
money received by it except as the Trustee may agree in writing with the
Company. Money held in trust by the Trustee need not be segregated from other
funds except to the extent required by the law.

                  (g) The Trustee shall not be deemed to have notice of any
fact or matter with respect hereto, including without limitation, the occurrence
of a Default or Event of Default, unless such fact or matter is actually known
by a Trust Officer charged with responsibility for administering this Indenture
or unless in writing received by a Trust Officer and making specific reference
to this Indenture.

                  Section 7.2. RIGHTS OF TRUSTEE.

                  Subject to Section 7.1 hereof:

                  (a) The Trustee may rely on and shall be protected in
acting or refraining from acting upon any document (including without limitation
any Company Order or Officers' Certificate) reasonably believed by it to be
genuine and to have been signed or presented by the proper person. The Trustee
need not investigate any fact or matter stated in any document.

                  (b) Before the Trustee acts or refrains from acting,
including whenever the Trustee deems it desirable that a matter be proved or
established prior to it acting or refraining from acting, it may require an
Officers' Certificate or an Opinion of Counsel, or both, which shall conform to
the provisions of Section 10.5 hereof. The Trustee shall be protected and shall
not be liable for any action it takes or omits to take in good faith in reliance
on such certificate or opinion.

                  (c) The Trustee may act through agents and shall not be
responsible for the misconduct or negligence of any agent (other than the
negligence or willful misconduct of an agent who is an employee of the Trustee)
appointed by it with due care.

                  (d) The Trustee shall not be liable for any action it
takes or omits to take in good faith which it reasonably believes to be
authorized or within its rights or powers; provided that the Trustee's conduct
does not constitute negligence or bad faith.

                  (e) The Trustee may consult with counsel of its
selection, and the advice or opinion of such counsel as to matters of law shall
be full and complete authorization and



                                       63

protection from liability in respect of any action taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

                  Section 7.3. INDIVIDUAL RIGHTS OF TRUSTEE.

                  The Trustee in its individual or any other capacity may become
the owner or pledgee of Notes and may make loans to, accept deposits from,
perform services for or otherwise deal with the Company, or any Affiliates
thereof, with the same rights it would have if it were not Trustee. Any Agent
may do the same with like rights. The Trustee, however, shall be subject to
Sections 7.10 and 7.11 hereof.

                  Section 7.4. TRUSTEE'S DISCLAIMER.

                  The Trustee makes no representation as to the validity or
adequacy of this Indenture or the Notes, it shall not be accountable for the
Company' use of the proceeds from the sale of Notes or any money paid to the
Company pursuant to the terms of this Indenture and it shall not be responsible
for any statement in the Notes or any document used in connection with the sale
of the Notes other than its certificate of authentication.

                  Section 7.5. NOTICE OF DEFAULTS.

                  If a Default occurs and is continuing and if it is known to
the Trustee, the Trustee shall mail to each Holder notice of the Default within
90 calendar days after it occurs. Except in the case of a Default in payment of
the principal, Redemption Price or Purchase Price of, and accrued interest on,
any Note, the Trustee may withhold the notice if and so long as the board of
directors of the Trustee, the executive committee or any trust committee of such
board and/or its Trust Officers in good faith determine(s) that withholding the
notice is in the interest of the Holders.

                  Section 7.6. REPORTS BY TRUSTEE TO HOLDERS.

                  If required by TIA Section 313(a), within 60 calendar days
after May 15 of any year, commencing the May 15th following the date of this
Indenture, the Trustee shall mail to each Holder a brief report dated as of
such May 15 that complies with TIA Section 313(a). The Trustee also shall
comply with TIA Section 313(b)(2). The Trustee shall also transmit by mail
all reports as required by TIA Section 313(c) and TIA Section 313(d). A copy
of each report at the time of its mailing to Holders shall be filed with the
SEC and each stock exchange on which the Notes are listed. The Company shall
promptly notify the Trustee when the Notes are listed on any stock exchange.

                  Section 7.7. COMPENSATION AND INDEMNITY.

                  (a) The Company shall pay to the Trustee from time to
time such reasonable compensation as shall be agreed in writing between the
Company and the Trustee for its services hereunder (which compensation shall not
be limited by any provision of law in regard to the compensation of a trustee of
an express trust). The Company shall reimburse the Trustee upon request for all
reasonable disbursements, expenses and advances incurred or made by it in
connection with its duties under this Indenture, including the reasonable
compensation, disbursements and expenses of the Trustee's agents and counsel.

                                       64
<PAGE>

                  (b) The Company agrees to indemnify each of the Trustee
and any predecessor Trustee for, and hold it harmless against, any and all loss,
damage, claim, liability, reasonable expense (including but not limited to
reasonable attorneys' fees and expenses) or taxes (other than taxes based on the
income of the Trustee) incurred by it in connection with the acceptance or
performance of its duties under this Indenture including the reasonable costs
and expenses of defending itself against any claim or liability in connection
with the exercise or performance of any of its powers or duties hereunder
(including, without limitation, settlement costs). The Trustee shall notify the
Company in writing promptly of any claim asserted against the Trustee for which
it may seek indemnity. However, the failure by the Trustee to so notify the
Company shall not relieve the Company of their obligations hereunder unless and
to the extent such failure results in the forfeiture by the Company of
substantial rights and defenses.

                  (c) Notwithstanding the foregoing, the Company need not
reimburse the Trustee for any expense or indemnify it against any loss or
liability incurred by the Trustee through its negligence or bad faith. To secure
the payment obligations of the Company in this Section 7.7, the Trustee shall
have a lien prior to the Notes on all money or property held or collected by the
Trustee in its capacity as such, except such money or property held in trust to
pay principal, Redemption Price or Change of Control Purchase Price of, and
accrued interest on, particular Notes. The obligations of the Company under this
Section 7.7 to compensate and indemnify the Trustee and each predecessor Trustee
and to pay or reimburse the Trustee and each predecessor Trustee for expenses,
disbursements and advances shall survive the satisfaction and discharge of this
Indenture, including the termination or rejection hereof in any bankruptcy
proceeding to the extent permitted by law.

                  (d) When the Trustee incurs expenses or renders services
after an Event of Default specified in Section 6.1(a)(vii), (viii) or (ix)
hereof occurs, the expenses and the compensation for the services are intended
to constitute expenses of administration under the SIPA or any Bankruptcy Law.

                  (e) For purposes of this Section 7.7, the term "Trustee"
shall include any trustee appointed pursuant to Article 9.

                  Section 7.8. REPLACEMENT OF TRUSTEE.

                  (a) The Trustee may resign by so notifying the Company in
writing, such resignation to become effective upon the appointment of a
successor Trustee. The Holders of a majority in principal amount of the
outstanding Notes may remove the Trustee by notifying the removed Trustee in
writing and may appoint a successor Trustee with the Company's written consent
which consent shall not be unreasonably withheld. The Company may remove the
Trustee at its election if:

                           (i) the Trustee fails to comply with Section
                  7.10 hereof;

                           (ii) the Trustee is adjudged a bankrupt or
                  an insolvent;

                           (iii) a receiver or other public officer takes charge
                  of the Trustee or its property; or

                                       65
<PAGE>

                           (iv) the Trustee otherwise becomes incapable of
                  acting.

                  (b) If the Trustee resigns or is removed or if a vacancy
exists in the office of Trustee for any reason, the Company shall promptly
appoint a successor Trustee.

                  (c) If a successor Trustee does not take office within 60
calendar days after the retiring Trustee resigns or is removed, the retiring
Trustee, the Company or any Holder of outstanding Notes may petition any court
of competent jurisdiction for the appointment of a successor Trustee. If the
Trustee fails to comply with Section 7.10 hereof, any Holder may petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee.

                  (d) A successor Trustee shall deliver a written
acceptance of its appointment to the retiring Trustee and to the Company.

                  (e) Immediately following such delivery, the retiring
Trustee shall, subject to its rights under Section 7.7 hereof, transfer all
property held by it as Trustee to the successor Trustee, the resignation or
removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. A successor Trustee shall mail notice of its succession to each
Holder. Notwithstanding replacement of the Trustee pursuant to this Section 7.8,
the Company' obligations under Section 7.7 hereof shall continue for the benefit
of the retiring Trustee.

                  Section 7.9. SUCCESSOR TRUSTEE BY CONSOLIDATION, MERGER OR
CONVERSION.

                  If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust assets to, another
corporation or national banking association, subject to Section 7.10 hereof, the
successor corporation or national banking association without any further act
shall be the successor Trustee.

                  Section 7.10. ELIGIBILITY; DISQUALIFICATION.

                  This Indenture shall always have a Trustee who satisfies
the requirements of TIA Section  310(a)(1), (2) and (5) in every respect. The
Trustee shall have a combined capital and surplus of at least $100,000,000 as
set forth in its most recent published annual report of condition. The
Trustee shall comply with TIA Section 310(b), including the provision in TIA
Section 310(b)(1); PROVIDED that there shall be excluded from the operation
of TIA Section 310(b)(1) any indenture or indentures under which other
securities, or conflicts of interest or participation in other securities, of
the Company are outstanding if the requirements for exclusion set forth in
TIA Section 310(b)(1) are met.

                  Section 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST
COMPANY.

                  The Trustee shall comply with TIA Section 311(a), excluding
any creditor relationship listed in TIA Section 311(b). A Trustee who has
resigned or been removed shall be subject to TIA Section 311(a) to the extent
indicated therein.

                  Section 7.12. PAYING AGENTS.

                  The Company shall cause each Paying Agent other than the
Trustee or an Affiliate of the Trustee to execute and deliver to it and the
Trustee an instrument in which such agent shall agree with the Trustee,
subject to the provisions of this Section 7.12:

                  (a) that it will hold all sums held by it as agent for
the payment of principal, Redemption Price or Change of Control Purchase Price
of, and accrued interest on, the Notes (whether such sums have been paid to it
by the Company or by any obligor on the Notes) in trust for the benefit of
Holders of the Notes or the Trustee;

                  (b) that it will at any time during the continuance of
any Event of Default, upon written request from the Trustee, deliver to the
Trustee all sums so held in trust by it together with a full accounting thereof;
and

                  (c) that it will give the Trustee written notice within
three (3) Business Days of any failure of the Company (or by any obligor on the
Notes) in the payment of any installment of the principal, Redemption Price or
Change of Control Purchase Price of, and accrued interest on, the Notes when the
same shall be due and payable.

                                  ARTICLE VIII.

                        AMENDMENT, SUPPLEMENT AND WAIVER

                  Section 8.1. WITHOUT CONSENT OF HOLDERS.

                  (a) Without the consent of any Holders, the Company, and
the Trustee, at any time and from time to time, may enter into one or more
indentures supplemental to this Indenture for any of the following purposes:

                           (i) to evidence the succession of another Person to

                  covenants of the Company in this Indenture and in the Notes;
                  or

                           (ii) to add to the covenants of the Company for the
                  benefit of the Holders, or to surrender any right or power
                  herein conferred upon the Company; or

                          (iii) to add additional Events of Default; or

                          (iv) to provide for uncertificated Notes in
                  addition to or in place of the certificated Notes; or

                           (v) to evidence and provide for the acceptance of
                  appointment under this Indenture by a successor Trustee; or

                                       67
<PAGE>

                           (vii) to cure any ambiguity, to correct or supplement
                  any provision in this Indenture which may be defective or
                  inconsistent with any other provision in this Indenture, or to
                  make any other provisions with respect to matters or questions
                  arising under this Indenture, provided that such actions
                  pursuant to this clause shall not adversely affect the
                  interests of the Holders in any material respect; or

                           (viii) to provide for the issuance of the Exchange
                  Notes and Private Exchange Notes, which will have terms
                  substantially identical to the other outstanding Notes except
                  for the requirement of a Private Placement Legend and related
                  transfer restrictions under the Securities Act and this
                  Indenture and as to the applicability of additional interest
                  payable as provided in Section 2.13, and which will be
                  treated, together with any other outstanding Notes, as a
                  single issue of securities, or

                           (ix) to comply with any requirements of the SEC in
                  order to effect and maintain the qualification of this
                  Indenture under the Trust Indenture Act.

                  (b) The Trustee is hereby authorized to join with the
Company in the execution of any supplemental indenture authorized or permitted
by the terms of this Indenture and to make any further appropriate agreements
and stipulations which may be therein contained, but the Trustee shall not be
obligated to enter into any such supplemental indenture which adversely affects
its own rights, duties or immunities under this Indenture.

                  Section 8.2. WITH CONSENT OF HOLDERS.

                  (a) With the consent of the Holders of not less than a
majority in aggregate principal amount of the outstanding Notes, the Company and
the Trustee may enter into an indenture or indentures supplemental to this
Indenture for the purpose of adding any provisions to or changing in any manner
or eliminating any of the provisions of this Indenture or of modifying in any
manner the rights of the Holders under this Indenture, including the definitions
therein; PROVIDED, HOWEVER, that no such supplemental indenture shall, without
the consent of the Holder of each outstanding Note affected thereby:

                           (i) change the Stated Maturity of any Note or of any
                  installment of interest on any Note, or reduce the amount
                  payable in respect of the principal thereof or the rate of
                  interest thereon or any premium payable thereon, or reduce the
                  amount that would be due and payable on acceleration of the
                  maturity thereof, or change the place of payment where, or the
                  coin or currency in which, any Note or any premium or interest
                  thereon is payable, or impair the right to institute suit for
                  the enforcement of any such payment on or after the Stated
                  Maturity thereof; or

                           (ii) reduce the percentage in aggregate principal
                  amount of the outstanding Notes, the consent of whose Holders
                  is required for any such supplemental indenture, or the
                  consent of whose Holders is required for any



                                       68
<PAGE>

                  waiver (of compliance with certain provisions of this
                  Indenture or certain defaults hereunder and their
                  consequences) provided for in this Indenture; or

                           (iii) modify in a manner adverse to the Holders the
                  obligations of the Company to make a Change of Control Offer
                  to Purchase upon a Change of Control or a Net Proceed Offer
                  upon an Asset Sale; or

                           (iv) subordinate, in right of payment, the
                  Notes to any other Indebtedness of the Company; or

                           (v) modify any of the provisions of this proviso to
                  Section 8.2 or provisions relating to waiver of defaults or
                  certain covenants contained in Section 6.2, 6.4 or 6.7 hereof,
                  except to increase any such percentage required for such
                  actions or to provide that certain other provisions of this
                  Indenture cannot be modified or waived without the consent of
                  the Holder of each outstanding Note affected thereby.

                  (b) After a modification, amendment, supplement or waiver
under this Section 8.2 becomes effective, the Company shall mail to the Holders
a notice briefly describing the modification, amendment, supplement or waiver.
Any failure of the Company to mail such notice, or any defect therein, shall
not, however, in any way impair or affect the validity of any such modification,
amendment, supplement or waiver.

                  (c) It shall not be necessary for the consent of the
Holders under this Section 8.2 to approve the particular form of any proposed
amendment, modification, supplement or waiver, but it shall be sufficient if
such consent approves the substance thereof.

                  Section 8.3.      COMPLIANCE WITH TRUST INDENTURE ACT.

                  Every amendment to or supplement of this Indenture or the
Notes shall comply with the TIA as then in effect.

                  Section 8.4.      REVOCATION AND EFFECT OF CONSENTS.

                  (a) Until a modification, amendment, supplement, waiver
or other action becomes effective, a consent to it by a Holder of a Note is a
continuing consent conclusive and binding upon such Holder and every subsequent
Holder of the same Note or portion thereof, and of any Note issued upon the
transfer thereof or in exchange therefor or in place thereof, even if notation
of the consent is not made on any such Note. Any such Holder or subsequent
Holder, however, may revoke the consent as to his Note or portion of a Note, if
the Trustee receives the notice of revocation before the date the modification,
amendment, supplement, waiver or other action becomes effective.

                  (b) The Company may, but shall not be obligated to, fix a
record date for the purpose of determining the Holders entitled to consent to
any modification, amendment, supplement, or waiver. If a record date is fixed,
then, notwithstanding the preceding paragraph, those Persons who were Holders at
such record date (or their duly designated proxies), and only such Persons,
shall be entitled to consent to such modification, amendment, supplement, or

                                       69
<PAGE>

waiver or to revoke any consent previously given, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or
effective for more than 120 calendar days after such record date unless the
consent of the requisite number of Holders has been obtained. After a
modification, amendment, supplement, waiver or other action becomes effective,
it shall bind every Noteholder.

                  Section 8.5. NOTATION ON OR EXCHANGE OF NOTES.

                  If a modification, amendment, supplement or waiver changes the
terms of a Note, the Trustee may request the Holder of the Note to deliver it to
the Trustee. In such case, the Trustee shall place an appropriate notation on
the Note about the changed terms and return it to the Holder. Alternatively, if
the Company or the Trustee so determine, the Company in exchange for the Note
shall issue and the Trustee shall authenticate a new Note that reflects the
changed terms. Failure to make the appropriate notation or issue a new Note
shall not affect the validity and effect of such modification, amendment,
supplement or waiver.

                  Section 8.6. TRUSTEE TO SIGN AMENDMENTS, ETC.

                  The Trustee shall sign any modification, amendment, supplement
or waiver authorized pursuant to this Indenture if the modification, amendment,
supplement or waiver does not adversely affect the rights, duties, liabilities
or immunities of the Trustee. If it does, the Trustee may, but need not, sign
it. In signing or refusing to sign such modification, amendment, supplement or
waiver, the Trustee shall be entitled to receive and, subject to Section 7.1
hereof, shall be fully protected in relying upon an Officers' Certificate and an
Opinion of Counsel stating that such modification, amendment, supplement or
waiver is authorized or permitted by this Indenture and such supplemental
indenture constitutes the legal, valid and binding obligation of the Company
enforceable against each of them in accordance with its terms (subject to
customary exceptions). The Company may not sign a modification, amendment or
supplement until the Board of Directors of the Company approves it.

                                   ARTICLE IX.

                       DISCHARGE OF INDENTURE; DEFEASANCE

                  (a) The Company may terminate its obligations under this
Indenture, except the obligations referred to in the last paragraph of this
Section 9.1 when (i) either: (A) all Notes theretofore authenticated and
delivered have been delivered to the Trustee for cancellation, or (B) all such
Notes not theretofore delivered to the Trustee for cancellation (1) have become
due and payable, or (2) will become due and payable within 60 calendar days or
are to be called for redemption within 60 calendar days (a "DISCHARGE") under
irrevocable arrangements satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the Company, and
the Company has irrevocably deposited or caused to be deposited with the Trustee
funds in an amount sufficient to pay and discharge the entire indebtedness on
the Notes, not theretofore delivered to the Trustee for cancellation, for
principal, Redemption Price of, and accrued interest on, the Notes to the Stated
Maturity or date of redemption; (ii) the



                                       70
<PAGE>

Company has paid or caused to be paid all other sums then due and payable
hereunder by the Company; and (iii) the Company has delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent under this Indenture relating to the satisfaction and
discharge of this Indenture have been complied with.

                  (b) After such delivery the Trustee upon request shall
acknowledge in writing the satisfaction and discharge of the Company's
obligations under the Notes and this Indenture except for those surviving
obligations specified below.

                  (c) Notwithstanding the satisfaction and discharge of
this Indenture, the obligations of the Company in Sections 2.2, 2.3, 2.4, 2.5,
2.6, 2.7, 2.8, 2.9, 2.13, 4.15, 9.5, 9.6 and 9.8, the rights, powers, duties and
immunities of the Trustee hereunder (including claims of, or payments to, the
Trustee under or pursuant to Section 7.7 hereof), the provisions of Article III
and the Trustee's and Paying Agent's obligations in Section 9.8 shall survive
until the Notes are no longer outstanding. Upon such satisfaction and discharge,
only the obligations of the Company in Sections 2.9, 7.7, 9.5, 9.6 and 9.8
hereof shall survive.

                  Section 9.2. LEGAL DEFEASANCE.

                  The Company may at its option be discharged from its
obligations with respect to the Notes on the date the conditions set forth in
Section 9.4 below are satisfied (hereinafter, "LEGAL DEFEASANCE"). For this
purpose, such Legal Defeasance means that the Company shall be deemed to have
paid and discharged the entire indebtedness represented by the Notes and to have
satisfied all its other obligations under such Notes and this Indenture insofar
as such Notes are concerned (and the Trustee, at the expense of the Company,
shall, subject to Section 9.6 hereof, execute proper instruments acknowledging
the same), except for the following which shall survive until otherwise
terminated or discharged hereunder: (i) the rights of Holders of outstanding
Notes to receive solely from the trust funds described in Section 9.4 hereof and
as more fully set forth in such Section, payments in respect of the principal,

powers, trusts, duties and immunities of the Trustee hereunder (including claims

                  Section 9.3. COVENANT DEFEASANCE.

                  At the option of the Company, the Company shall be released
from their respective obligations under Sections 4.2 through 4.14 hereof,
inclusive, Section 4.16, clause (a)(ii) of Section 5.1 hereof (with respect to
Sections 4.2 through 4.14 hereof, inclusive, and Section 4.16) and Section
6.1(a)(iii) only to the extent related to compliance with clause (a)(ii) of
Section 5.1 and Section 6.1(a)(vi), with respect to the outstanding Notes on and
after the date the conditions set forth in Section 9.4 hereof are satisfied
(hereinafter, "COVENANT DEFEASANCE"), any omission to comply with such
obligations shall not constitute a Default or Event of Default, and the Notes
shall thereafter be deemed not to be outstanding for purposes of any direction,

consent, declaration or act of the Holders (and the consequences thereof) in
connection with such covenants but shall continue to be outstanding for all
other purposes hereunder. For this purpose, such Covenant Defeasance means that
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such specified Section or
portion thereof, whether directly or indirectly by reason of any reference
elsewhere herein to any such specified Section or portion thereof or by reason
of any reference in any such specified Section or portion thereof to any other
provision herein or in any other document, but the remainder of this Indenture
and the Notes shall be unaffected thereby.

                  Section 9.4. CONDITIONS TO LEGAL DEFEASANCE OR COVENANT
DEFEASANCE.

                  The following shall be the conditions to application of
Section 9.2 or Section 9.3 hereof to the outstanding Notes:

                  (1) the Company must irrevocably have deposited or caused
to be deposited with the Trustee (or another trustee satisfying the requirements
of Section 7.10 hereof who shall agree to comply with the provisions of this
Article IX applicable to it) as trust funds in trust for the purpose of making
the following payments, specifically pledged as security for, and dedicated
solely to the benefits of the Holders of such Notes: (A) money in an amount, or
(B) U.S. Government Obligations which through the scheduled payment of principal
and interest in respect thereof in accordance with their terms will provide, not
later than the due date of any payment, money in an amount, or (C) a combination
thereof, in each case sufficient without reinvestment, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee (or other qualifying trustee) to pay
and discharge, the entire indebtedness in respect of the principal, Redemption
Price or Change of Control Purchase Price of, and accrued interest on, such
Notes on the Stated Maturity thereof or (if the Company has made irrevocable
arrangements satisfactory to the Trustee for the giving of notice of redemption
by the Trustee in the name and at the expense of the Company) the Redemption
Date thereof, as the case may be, in accordance with the terms of this Indenture
and such Notes;

                  (2) in the case of Legal Defeasance, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (A) the Company
have received from, or there has been published by, the Internal Revenue Service
a ruling or (B) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case (A) or (B) to the effect that,
and based thereon such opinion shall confirm that, the Holders of such Notes
will not recognize gain or loss for federal income tax purposes as a result of
the Legal Defeasance to be effected with respect to such Notes and will be
subject to federal income tax on the same amount, in the same manner and at the
same times as would be the case if such Legal Defeasance were not to occur;

                  (3) in the case of Covenant Defeasance, the Company shall
have delivered to the Trustee an Opinion of Counsel (i) to the effect that the
Holders of such outstanding Notes will not recognize gain or loss for federal
income tax purposes as a result of the Covenant Defeasance to be effected with
respect to such Notes and will be subject to federal income tax on the same
amount, in the same manner and at the same times as would be the case if such

                                       72
<PAGE>

Covenant Defeasance were not to occur or (ii) that the Company has received
from, or there has been published by, the Internal Revenue Service a ruling to
the foregoing effect;

                  (4) no Default or Event of Default with respect to the
outstanding Notes shall have occurred and be continuing at the time of such
deposit after giving effect thereto or, in the case of Legal Defeasance, either:
(A) the Company shall have delivered to the Trustee an Opinion of Counsel to the
effect that, based upon existing precedents, if the matter were properly
briefed, a court should hold that the deposit of moneys and/or U.S. Government
Obligations as provided in clause (1) of this Section 9.4 would not constitute a
preference voidable under Section 547 or 548 of the federal bankruptcy laws; or
(B) no Default or Event of Default relating to bankruptcy or insolvency shall
have occurred and be continuing at any time on or prior to the 91st day after
the date of such deposit (it being understood that this condition shall not be
deemed satisfied until after such 91st day);

                  (5) such Legal Defeasance or Covenant Defeasance shall
not cause the Trustee to have a conflicting interest within the meaning of the
TIA (assuming all Notes are in default within the meaning of such Act);

                  (6) such Legal Defeasance or Covenant Defeasance shall
not result in a breach or violation of, or constitute a default under, any other
agreement or instrument to which the Company is a party or by which it is bound;

                  (7) such Legal Defeasance or Covenant Defeasance shall
not result in the trust arising from such deposit constituting an investment
company within the meaning of the Investment Company Act of 1940, as amended,
unless such trust shall be registered under such Act or exempt from registration
thereunder; and

                  (8) the Company shall have delivered to the Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent with respect to such Legal Defeasance or Covenant
Defeasance have been complied with.

                  Section 9.5.     DEPOSITED MONEY AND U.S. GOVERNMENT
                                   OBLIGATIONS TO BE HELD IN TRUST; OTHER
                                   MISCELLANEOUS PROVISIONS.

                  (a) All money and U.S. Government Obligations (including
the proceeds thereof) deposited with the Trustee pursuant to Section 9.4 hereof
in respect of the outstanding Notes shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Notes and this Indenture, to
the payment, either directly or through any Paying Agent as the Trustee may
determine, to the Holders of such Notes, of all sums due and to become due
thereon in respect of principal, Redemption Price or Change of Control Purchase
Price of, and accrued interest on, the Notes, but such money need not be
segregated from other funds except to the extent required by law. The Trustee
shall be under no duty to invest such money or U.S. Government Obligations. The
Company shall pay and indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against the U.S. Government Obligations deposited
pursuant to Section 9.4 hereof or the principal, Redemption Price or Change of
Control Purchase Price of, and accrued interest on, the Notes received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of the outstanding Notes.

                                       73

<PAGE>

                  (b) Anything in this Article IX to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon Company Order any money or U.S. Government Obligations held by it as
provided in Section 9.4 hereof which, in the opinion of a nationally-recognized
firm of independent public accountants expressed in a written certification
thereof delivered to the Trustee, are in excess of the amount thereof which
would then be required to be deposited to effect an equivalent Legal Defeasance
or Covenant Defeasance.

                  Section 9.6.      REINSTATEMENT.

                  If the Trustee or Paying Agent is unable to apply any money or
U.S. Government Obligations in accordance with Section 9.1, 9.2 or 9.3 hereof by
reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the obligations of the Company under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to this Article IX until such time as the Trustee or Paying Agent is permitted
to apply all such money or U.S. Government Obligations in accordance with
Section 9.1, 9.2 or 9.3 hereof; PROVIDED, HOWEVER, that if the Company has made
any payment of principal, Redemption Price or Purchase Price of, and accrued
interest on, any Notes because of the reinstatement of its Obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the money or U.S. Government Obligations held by the
Trustee or Paying Agent.

                  Section 9.7.      MONEYS HELD BY PAYING AGENT.

                  In connection with the satisfaction and discharge of this
Indenture, all moneys then held by any Paying Agent under the provisions of this
Indenture shall, upon demand of the Company, be paid to the Trustee, or if
sufficient moneys have been deposited pursuant to Section 9.1 or 9.4 hereof, to
the Company, and thereupon such Paying Agent shall be released from all further
liability with respect to such moneys.

                  Section 9.8. MONEYS HELD BY TRUSTEE.

                  Any moneys deposited with the Trustee or any Paying Agent or
then held by the Company in trust for the payment of the principal, Redemption
Price or Change of Control Purchase Price of, and accrued interest on, any Note
that are not applied but remain unclaimed by the Holder of such Note for two
years after the date upon which the principal, Redemption Price or Change of
Control Purchase Price of, and accrued interest on, such Note shall have
respectively become due and payable shall be repaid to the Company upon Company
Order, or if such moneys are then held by the Company in trust, such moneys
shall be released from such trust; and the Holder of such Note entitled to
receive such payment shall thereafter, as an unsecured general creditor, look
only to the Company for the payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money shall thereupon cease;
PROVIDED, HOWEVER, that the Trustee or any such Paying Agent, before being
required to make any such repayment, may, at the expense of the Company either
mail to each Holder affected, at the address shown in the register of the Notes
maintained by the Registrar pursuant to Section 2.3 hereof, or cause to be
published once a week for two successive weeks, in a newspaper published in the
English language, customarily published each Business Day and of general
circulation in

The City of New York, New York, a notice that such money remains unclaimed and
that, after a date specified therein, which shall not be less than 30 calendar
days from the date of such mailing or publication, any unclaimed balance of such
moneys then remaining will be repaid to the Company. After payment to the
Company or the release of any money held in trust by the Company, Holders
entitled to the money must look only to the Company for payment as general
creditors unless applicable abandoned property law designates another person.

                  (a) Any notice or communication shall be given in writing
and delivered in person, sent by facsimile, delivered by commercial courier

Failure to mail a notice or communication to a Holder or any defect in it shall
not affect its sufficiency with respect to other Holders. In case by reason of
the suspension of regular mail service, or by reason of any other cause, it
shall be impossible to mail any notice as required by this Indenture, then such
method of notification as shall be made with the approval of the Trustee shall
constitute a sufficient mailing of such notice.

                  Section 10.3. COMMUNICATIONS BY HOLDERS WITH OTHER HOLDERS.

                  Holders may communicate pursuant to TIA ss.312(b) with other

Company, the Trustee, the Registrar and anyone else shall have the protection of
TIA ss. 312(c).

                  Section 10.4. CERTIFICATE AND OPINION AS TO CONDITIONS
PRECEDENT.

                  Upon any request or application by the Company to the Trustee
to take any action under this Indenture, the Company shall furnish to the
Trustee at the request of the Trustee:

                  (a) an Officers' Certificate (which shall include the
statements set forth in Section 10.5 below) in form and substance reasonably
satisfactory to the Trustee stating that, in the opinion of the signers, all
conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with; and

                  (b)  an Opinion of Counsel (which shall include the
statements set forth in Section 10.5 below) in form and substance reasonably
satisfactory to the Trustee stating that, in the opinion of such counsel, all
such conditions precedent have been complied with.

                  Section 10.5. STATEMENTS REQUIRED IN CERTIFICATE AND OPINION.

                  (a) Each certificate and opinion with respect to
compliance with a condition or covenant provided for in this Indenture shall
include:

                           (i) a statement that the Person making such
certificate or opinion has read such covenant or condition;

                           (ii) a brief statement as to the nature and scope of
the examination or investigation upon which the statements or opinions contained
in such certificate or opinion are based;

                           (iii) a statement that, in the opinion of such
Person, it or he has made such examination or investigation as is necessary to
enable it or him to express an informed opinion as to whether or not such
covenant or condition has been complied with; and

                           (iv) a statement as to whether or not, in the opinion
of such Person, such covenant or condition has been complied with.

                  (b) In any case where several matters are required to be
certified by, or covered by an opinion of, any specified Person, it is not
necessary that all such matters be certified by, or covered by the opinion of,
only one such Person or that they be so certified or



                                       76
<PAGE>

covered by only one document, but one such Person may certify or give an opinion
with respect to some matters and one or more other such Persons as to other
matters, and any such Person may certify or give an opinion as to such matters
in one or several documents.

                  (c) Any certificate or opinion of an officer of the
Company may be based, insofar as it relates to legal matters, upon a certificate
or opinion of, or representations by, counsel, unless such officer knows, or in
the exercise of reasonable care should know, that the certificate or opinion or
representations with respect to the matters, upon which his certificate or
opinion is based are erroneous. Any such certificate or opinion of counsel may
be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of an Company stating

of such Company, unless such counsel knows or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to

consolidated and form one instrument.

                  Section 10.6. WHEN TREASURY NOTES DISREGARDED.

                  In determining whether the Holders of the required aggregate
principal amount of Notes have concurred in any direction, waiver or consent,
Notes owned by the Company or by any Affiliate of the Company shall be
disregarded as though they were not outstanding, except that for the purposes of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes which the Trustee actually knows are so
owned shall be so disregarded. Notes so owned which have been pledged in good
faith shall not be disregarded if the pledgee establishes to the satisfaction of
the Trustee the pledgee's right so to act with respect to the Notes.

                  Section 10.7. RULES BY TRUSTEE AND AGENTS.

                  The Trustee may make reasonable rules for action by or
meetings of Holders and any Registrar or Paying Agent may make reasonable rules
for their functions provided that no such rule shall conflict with the terms of
this Indenture or the TIA.

                  Section 10.8. BUSINESS DAYS; LEGAL HOLIDAYS.

                  A "BUSINESS DAY" is a day that is not a Legal Holiday. A
"LEGAL HOLIDAY" is a Saturday, a Sunday, a federally-recognized holiday or a day
on which banking institutions are not required to be open in the State of New
York or the state in which the Corporate Trust Office is located. If a payment
date is a Legal Holiday at a place of payment, payment may be made at that place

accrue for the intervening period.

JURISDICTION OF ANY NEW YORK STATE COURT SITTING IN THE BOROUGH OF MANHATTAN IN
THE CITY OF NEW YORK OR ANY FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN IN
THE CITY OF NEW YORK IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF
OR RELATING TO THIS INDENTURE AND THE NOTES, AND IRREVOCABLY ACCEPTS FOR ITSELF
AND IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, JURISDICTION OF
THE AFORESAID COURTS. THE COMPANY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT THAT

WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF THE VENUE OF ANY SUCH SUIT,
ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT AND ANY CLAIM THAT ANY SUCH SUIT,
ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE TRUSTEE OR ANY
HOLDER OF THE NOTES TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO
COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE COMPANY IN ANY OTHER
JURISDICTION.

employee, as such, past, present or future, of the Company or of any successor
corporation or against the property or assets of any such stockholder, officer,
employee, partner, affiliate, beneficiary or director, either directly or
through the Company, or any successor corporation thereof, whether by virtue of
any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly understood that this
Indenture and the Notes are solely obligations of the Company, and that no such
personal liability whatever shall attach to, or is or shall be incurred by, any
stockholder, officer, employee, partner, affiliate, beneficiary or director of
the Company, or any successor corporation or partnership thereof, because of the
creation of the Indebtedness hereby authorized, or under or by reason of the

                  The Company shall qualify this Indenture under the TIA in

                          FORM OF REVERSE SIDE OF NOTE

                          9 1/2% Senior Notes due 2004

1. INTEREST

                  LaBranche & Co Inc., a Delaware corporation (the "COMPANY"),
promises, subject to the preceding sentence, to pay interest on the principal
amount of this Note at the rate per annum shown above.

                  The Company will pay interest semiannually in arrears on each
Interest Payment Date of each year commencing February 15, 2000. Interest on the
Notes will accrue from the most recent date to which interest has been paid on
the Notes or, if no interest has been paid, from the Issue Date. The Company
shall pay interest on overdue principal or premium, if any (plus interest on
such interest to the extent lawful), at the rate borne by the Notes to the
extent lawful. Interest will be computed on the basis of a 360-day year of
twelve 30-day months.

                  The Company shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal and,
to the extent such payments are lawful, interest on overdue installments of
interest, without regard to any applicable grace periods ("DEFAULTED INTEREST")
at a rate equal to the rate shown on this Note, as provided in the Indenture.

2. METHOD OF PAYMENT

                  By at least 10:00 a.m. (New York City time) on the date on
which any principal of, premium, if any, or interest on any Note is due and
payable, the Company shall irrevocably deposit with the Trustee or the Paying
Agent money sufficient to pay such principal, premium, if any, and/or interest.
The Company will pay interest (except Defaulted Interest) to the Persons who are
registered Holders of Notes at the close of business on the Record Date
preceding the interest payment date even if Notes are canceled, repurchased or
redeemed after the record date and on or before the relevant Interest Payment
Date. Holders must surrender Notes to a Paying Agent to collect principal
payments and premium payments, if any. The Company will pay principal and
interest in U.S. legal tender.

                  Payments in respect of Notes represented by a Global Note
(including principal, premium, if any, and interest) will be made by the
transfer of immediately available funds to the accounts specified by the
Depository Trust Company. The Company will make all payments in respect of a
Certificated Note (including principal, premium, if any, the Damage Amount, if
any, and interest) at the office or agency of the Company in The City of New
York maintained for such purposes, which, initially, will be the office of the
Trustee or an agent thereof; PROVIDED, HOWEVER, that payment of interest (which
shall include any Damage Amount), if any, may be made at the option of the
Company by check mailed to the Person entitled thereto as shown on the register
of the Notes maintained by the Registrar.

                                      A-5

Paying Agent, Registrar or co-registrar without notice to any Holder. The
Company may act as Paying Agent, Registrar or co-registrar.

4. INDENTURE

                  The Company has issued this Note pursuant to an Indenture
dated as of August 24, 1999, (as it may be amended or supplemented from time to
time in accordance with the terms thereof, the "INDENTURE"), between the Company
and the Trustee. The terms of this Note include those stated in the Indenture
and those made part of the Indenture by reference to the Trust Indenture Act of
1939 (15 U.S.C. ss.ss. 77aaa-77bbbb) as in effect on the date of the Indenture
(the "ACT"). Capitalized terms used herein and not defined herein have the
meanings ascribed thereto in the Indenture. The Notes are subject to all such
terms, and Holders are referred to the Indenture and the Act for a statement of
those terms. Each Holder by accepting a Note, agrees to be bound by all of the
terms and provisions of the Indenture.

                  This Note is a general unsecured senior obligation of the
Company. The Indenture imposes certain limitations on, among other things the
ability of the Company and its Restricted Subsidiaries to: incur Indebtedness,
make Restricted Payments, incur Liens, issue or sell Capital Interests of
Restricted Subsidiaries, consummate Asset Sales, enter into transactions with
Affiliates, enter into Sale and Leaseback transactions, create Unrestricted
Subsidiaries or consolidate or merge or transfer or convey all or substantially
all of the Company's and its Restricted Subsidiaries' assets.

5. REDEMPTION

                  The Notes are subject to redemption, at the option of the
Company, in whole or in part, at any time, upon not less than 30 nor more than
60 days prior written notice, mailed by first class mail to a holder's address
as it shall appear on the register maintained by the Registrar of the Notes at a
redemption price equal to 100% of the outstanding principal amount of the Notes,
plus a Make-Whole Premium, plus accrued and unpaid interest, if any, to the
Redemption Date (subject to the right of Holders of record on the relevant
regular record date to receive interest due on an interest payment date that is
on or prior to the Redemption Date).

                  If the Company does not redeem all of the Notes, the Trustee
shall select the Notes to be redeemed in compliance with the requirements of the
principal national securities exchange, if any, on which the Notes are listed
or, if the Notes are not then listed on a national securities exchange, on a PRO
RATA basis, by lot or in another fair and reasonable manner chosen at the
discretion of the Trustee. On and after any Redemption Date, interest will cease
to accrue on the Notes or portions thereof called for redemption unless the
Company shall fail to redeem any such Note.

6. REPURCHASE PROVISIONS

                  REPURCHASE UPON A CHANGE OF CONTROL. Upon the occurrence of a
Change of Control, the Company will make a Change of Control Offer to Purchase
all of the outstanding



                                      A-6
<PAGE>

Notes at a purchase price in cash equal to 101% of the principal amount at
Stated Maturity thereof, together with accrued interest, if any. For purposes of
the foregoing, a Change of Control Offer to Purchase shall be deemed to have
been made if: (i) within 30 days following the date of the consummation of a
transaction or series of transactions that constitutes a Change of Control, the
Company commences a Change of Control Offer to Purchase all outstanding Notes at
the Change of Control Purchase Price (provided that the running of such 30-day
period shall be suspended, for up to a maximum of 30 days, during any period
when the commencement of such Change of Control Offer to Purchase is delayed or
suspended by reason of any court's or governmental authority's review of or
ruling on any materials being employed by the Company to effect such Change of
Control Offer to Purchase, so long as the Company has used and continues to use
its best efforts to make and conclude such Change of Control Offer to Purchase
promptly) and (ii) all Notes properly tendered pursuant to the Change of Control
Offer to Purchase are purchased on the terms of such Change of Control Offer to
Purchase.

                  REPURCHASE WITH PROCEEDS FROM ASSET SALES. Any Net Cash
Proceeds from any Asset Sale that are not used to reinvest in Replacement Assets
and/or repay certain Indebtedness of the Company or a Restricted Subsidiary
within 360 days after an Asset Sale shall be applied to the repurchase of the
Notes. When the aggregate amount of unutilized Net Cash Proceeds (the "NET
PROCEEDS OFFER AMOUNT") exceeds $5,000,000, the Company shall make a Net
Proceeds Offer to purchase from all Holders, Notes in an aggregate principal
amount equal to the Net Proceeds Offer Amount, at a purchase price in cash equal
to 100% of the principal amount thereof, together with accrued interest, if any,
to the date of purchase. If the aggregate purchase price of Notes surrendered by
Holders exceeds the amount equal to the Net Proceeds Offer Amount, the Trustee
shall select the Notes to be purchased on a PRO RATA basis.

                  The Company will comply, to the extent applicable, with the
requirements of Rule 14e-1 under the Exchange Act and other securities laws or
regulations in connection with a Change of Control Offer to Purchase or a Net
Proceeds Offer.

7. DENOMINATIONS; TRANSFER; EXCHANGE

                  The Notes are in fully-registered form without coupons in
denominations of principal amount of $1,000 and any integral multiple thereof. A
Holder may transfer or exchange Notes only in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by law
or permitted by the Indenture. The Registrar need not register the transfer of
or exchange (i) any Notes selected for redemption (except, in the case of a Note
to be redeemed in part, the portion of the Note not to be redeemed) for a period
beginning 15 days before the mailing of a notice of Notes to be redeemed and
ending on the date of such mailing or (ii) any Notes for a period beginning 15
days before an interest payment date and ending on such interest payment date.

8. PERSONS DEEMED OWNERS

                  The registered holder of this Note may be treated as the owner
of it for all purposes.

                                      A-7
<PAGE>

9. UNCLAIMED MONEY

                  If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back to
the Company at its request unless an abandoned property law designates another
Person. After any such payment, Holders entitled to the money must look only to
the Company and not to the Trustee for payment.

10. DISCHARGE PRIOR TO REDEMPTION OR MATURITY

                  Subject to certain conditions set forth in the Indenture, the
Company at any time may terminate some or all of their obligations under the
Notes and the Indenture if the Company deposits with the Trustee U.S. legal
tender or U.S. Government Obligations for the payment of principal of, and
interest on, the Notes to redemption or maturity, as the case may be.

11. AMENDMENT, WAIVER

                  Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Notes may be amended with the written consent of the
Holders of at least a majority in principal amount of the then outstanding Notes
and (ii) any default (other than with respect to nonpayment or in respect of a
provision that cannot be amended without the written consent of each Holder
affected) or noncompliance with any provision may be waived with the written
consent of the Holders of a majority in principal amount of the then outstanding
Notes. Subject to certain exceptions set forth in the Indenture, without the
consent of any Holder, the Company and the Trustee may amend the Indenture or
the Notes to, among other things, to evidence the succession of another Person
to the Company and the assumption by any such successor of the covenants of the
Company in the Indenture and in the Notes; to add to the covenants of the
Company for the benefit of the Holders, or to surrender any right or power
herein conferred upon the Company; to add additional Events of Default; to
provide for uncertificated Notes in addition to or in place of the certificated
Notes; to evidence and provide for the acceptance of appointment under the
Indenture by a successor Trustee; to secure the Notes; to cure any ambiguity, to
correct or supplement any provision in the Indenture which may be defective or
inconsistent with any other provision in the Indenture, or to make any other
provisions with respect to matters or questions arising under the Indenture,
provided that such actions pursuant to this clause shall not adversely affect
the interests of the Holders in any material respect; to issue Exchange Notes or
Private Exchange Notes; or to comply with any requirements of the SEC in order
to effect and maintain the qualification of the Indenture under the Trust
Indenture Act.

12. DEFAULTS AND REMEDIES

                  If an Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount at Stated Maturity of the
outstanding Notes may declare all the Notes to be due and payable immediately.
Certain events of bankruptcy or insolvency are Events of Default which will
result in the Notes being due and payable immediately upon the occurrence of
such Events of Default.

                  Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Notes unless it receives reasonable indemnity or security. Subject to
certain limitations, Holders of a majority in



                                      A-8
<PAGE>

principal amount at Stated Maturity of the outstanding Notes may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders notice of any continuing Default or Event of Default (except a Default
or Event of Default in payment of principal or interest) if it determines that
withholding notice is in their interest.

13. TRUSTEE DEALINGS WITH THE COMPANY

                  Subject to certain limitations set forth in the Indenture, the
Trustee under the Indenture, in its individual or any other capacity, may become
the owner or pledgee of Notes and may otherwise deal with and collect
obligations owed to it by the Company or their Affiliates and may otherwise deal
with the Company or their affiliates with the same rights it would have if it
were not Trustee.

14. NO RECOURSE AGAINST OTHERS

                  No recourse for the payment of the principal, Redemption Price
or Purchase Price of, and accrued interest on, any of the Notes, or for any
claim based thereon or otherwise in respect thereof, and no recourse under or
upon any obligation, covenant or agreement of the Company in the Indenture or in
any supplemental indenture, or in any of the Notes, or because of the creation
of any Indebtedness represented thereby, shall be had against any stockholder,
officer, director, partner, affiliate, beneficiary or employee, as such, past,
present or future, of the Company or of any successor corporation or against the
property or assets of any such stockholder, officer, employee, partner,
affiliate, beneficiary or director, either directly or through the Company, or
any successor corporation thereof, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or
otherwise; it being expressly understood that the Indenture and the Notes are
solely obligations of the Company, and that no such personal liability whatever
shall attach to, or is or shall be incurred by, any stockholder, officer,
employee, partner, affiliate, beneficiary or director of the Company, or any
successor corporation or partnership thereof, because of the creation of the

                  2. EXCHANGE OFFER.

                  (a) The Company shall (A) prepare and, on or prior to 45 days
after the Issue Date (the "EXCHANGE FILING DATE"), file with the SEC a
Registration Statement under the Securities Act with respect to an offer by the
Company to the holders of the Notes to issue and deliver to such holders, in
exchange for Notes, a like principal amount of Exchange Notes, (B) use its
reasonable best efforts to cause the Registration Statement relating to the
Exchange Offer to be declared effective by the SEC under the Securities Act on
or prior to 90 days after the Issue Date (the "EXCHANGE EFFECTIVENESS DATE") and
(C) commence the Exchange Offer and use its reasonable best efforts to issue, on
or prior to 120 days after the Issue Date, the Exchange Notes. The offer and
sale of the Exchange Notes pursuant to the Exchange Offer shall be registered
pursuant to the Securities Act on the appropriate form (the "EXCHANGE
REGISTRATION STATEMENT") and duly registered or qualified under all applicable
state securities or Blue Sky laws and will comply with all applicable tender
offer rules and regulations under the Exchange Act and state securities or Blue
Sky laws. The Exchange Offer shall not be subject to any condition, other than
that the Exchange Offer does not violate any applicable law or interpretation of
the staff of the SEC. Upon consummation of the Exchange Offer in accordance with
this Section 2, the Company shall have no further registration obligations other
than with respect to (i) Private Exchange Notes, (ii) Exchange Notes held by
Participating Broker-Dealers and (iii) Notes or Exchange Notes as to which
Section 2(c) and Section 3 hereof applies. No securities shall be included in
the Exchange Registration Statement other than the Exchange Notes.

                                       5
<PAGE>

                  (b) The Company may require each holder of Notes as a
condition to its participation in the Exchange Offer to represent to the Company
and their counsel in writing (which may be contained in the applicable letter of
transmittal) that at the time of the consummation of the Exchange Offer (i) any
Exchange Notes received by such holder will be acquired in the ordinary course
of its business, (ii) such holder will have no arrangement or understanding with
any person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Notes and (iii) such holder is not an Affiliate
of the Company, or if it is an Affiliate of the Company, it will comply with the
registration and prospectus delivery requirements of the Securities Act, to the
extent applicable.

                  If, prior to consummation of the Exchange Offer, an Initial
Purchaser holds any Notes acquired by it and having, or that are reasonably
likely to be determined to have, the status of an unsold allotment in the
initial distribution, or any other holder of Notes is not entitled to
participate in the Exchange Offer, the Company upon the request of such Initial
Purchaser or any such holder shall, simultaneously with the delivery of the
Exchange Notes in the Exchange Offer, issue and deliver to such Initial
Purchaser and any such holder, in exchange (the "PRIVATE EXCHANGE") for such
Notes held by such Initial Purchaser and any such holder, a like principal
amount of debt securities of the Company that are identical in all material
respects to the Exchange Notes (the "PRIVATE EXCHANGE NOTES") (and that are
issued pursuant to the same indenture as the Exchange Notes). The Private
Exchange Notes shall bear the same CUSIP number as the Exchange Notes.

                  The Company and the Initial Purchasers acknowledge that the
staff of the SEC has taken the position that any broker-dealer that owns
Exchange Notes that were received by such broker-dealer for its own account in
the Exchange Offer (a "PARTICIPATING BROKER-DEALER") may be deemed to be an
"underwriter" within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Notes (other than a resale of an unsold allotment
resulting from the original offering of the Notes).

                  The Company and the Initial Purchasers also acknowledge that
it is the SEC staff's position that if the Prospectus contained in the Exchange
Registration Statement includes a plan of distribution containing a statement to
the above effect and the means by which Participating Broker-Dealers may resell
the Exchange Notes, without naming the Participating Broker-Dealers or
specifying the amount of Exchange Notes owned by them, such Prospectus may be
delivered by Participating Broker-Dealers to satisfy their prospectus delivery
obligations under the Securities Act in connection with resales of Exchange
Notes for their own accounts, so long as the Prospectus otherwise meets the
requirements of the Securities Act.

                  In light of the foregoing, if requested by a Participating
Broker-Dealer, the Company agrees (x) to use its reasonable best efforts to keep
the Exchange Registration Statement continuously effective for a period of up to
six months or such earlier date as each Participating Broker-Dealer shall have
notified the Company in writing that such Participating Broker-Dealer has resold
all Exchange Notes acquired in the Exchange Offer, (y) to comply with the
provisions of Section 5 of this Agreement, as they relate to the Exchange Offer
and the Exchange Registration Statement, and (z) to deliver to such
Participating Broker-Dealer a "cold comfort" letter of the independent public
accountants of the Company and a legal opinion as to



                                       6
<PAGE>

matters reasonably requested by such Participating Broker-Dealer relating to the
Exchange Registration Statement and the related Prospectus and any amendments or
supplements thereto.

                  Interest on the Exchange Notes and the Private Exchange Notes
will accrue from (A) the later of (i) the last interest payment date on which
interest was paid on the Notes surrendered in exchange therefor and (ii) if the
Notes are surrendered for exchange on a date in a period which includes the
record date for an interest payment date to occur on or after the date of such
exchange and as to which interest will be paid, the date of such interest
payment date or (B), if no interest has been paid on the Notes, from the Issue
Date.

                  In connection with each Exchange Offer, the Company shall:

                  (1) mail, or cause to be mailed, to each Holder of record
         entitled to participate in the Exchange a copy of the Prospectus
         forming part of the Exchange Registration Statement, together with an
         appropriate letter of transmittal and related documents;

                  (2) use its reasonable best efforts to keep the Exchange Offer
         open for not less than 20 business days after the date that notice of
         the Exchange Offer is mailed to Holders (or longer if required by
         applicable law);

                  (3) utilize the services of a depositary for the Exchange
         Offer with an address in the Borough of Manhattan, The City of New
         York;

                  (4) permit Holders to withdraw validly tendered Notes at any
         time prior to the close of business, New York time, on the last
         business day on which the Exchange Offer shall remain open; and

                  (5) otherwise comply in all material respects with all
         applicable laws, rules and regulations.

                  As soon as practicable after the close of the applicable
Exchange Offer and the applicable Private Exchange, if any, the Company shall:

                  (1) accept for exchange all Registrable Notes validly tendered
         and not validly withdrawn pursuant to the applicable Exchange Offer and
         the applicable Private Exchange, if any;

                  (2) deliver to the Trustee for cancellation all Registrable
         Notes so accepted for exchange and cause the Trustee to authenticate
         and deliver promptly to each Holder of Registrable Notes, Exchange
         Notes or Private Exchange Notes, as the case may be, equal in principal
         amount to the securities of such Holder so accepted for exchange.

                  The Exchange Notes and the Private Exchange Notes shall be
issued under (i) the Indenture or (ii) an indenture identical in all material
respects to the Indenture and that, in either case, has been qualified under the
TIA or is exempt from such qualification and shall provide that (a) the Exchange
Notes shall not be subject to the transfer restrictions set forth in the
Indenture and (b) the Private Exchange Notes shall be subject to the transfer
restrictions set forth in such indenture. The Indenture or such indenture shall
provide that the Exchange Notes, the



                                       7
<PAGE>

Private Exchange Notes and the Notes shall vote and consent together on all
matters as one class and that none of the Exchange Notes, the Private Exchange
Notes or the Notes will have the right to vote or consent as a separate class on
any matter.

                  (c) If, (i) because of any change in law or in currently
prevailing interpretations of the staff of the SEC, the Company is not permitted
to effect the Exchange Offer, (ii) the Exchange Offer is not consummated within
120 days of the Issue Date, (iii) any holder of any Private Exchange Notes so
requests in writing to the Company within 30 days after the consummation of the
Exchange Offer, or (iv) in the case of any Holder that participates in the
Exchange Offer, such Holder does not receive Exchange Notes on the date of the
exchange that may be sold without restriction under state and federal securities
laws (other than due solely to the status of such Holder as an affiliate of the
Company within the meaning of the Securities Act), then in the case of each of
clauses (i) to and including (iv) of this sentence, the Company shall promptly
deliver to the Holders and the Trustee written notice thereof (the "SHELF
NOTICE") and shall file a Shelf Registration pursuant to Section 3 hereof.

                  3. SHELF REGISTRATION.

                  If at any time a Shelf Notice is delivered as contemplated by
Section 2(c) hereof, then:

                  (a) SHELF REGISTRATION. The Company shall file with the SEC a
Registration Statement for an offering to be made on a continuous basis pursuant
to Rule 415 covering all of the Registrable Notes not exchanged in the Exchange
Offer, Private Exchange Notes and Exchange Notes as to which Section 2(c) (iv)
is applicable (the "INITIAL SHELF REGISTRATION"). The Company shall use its
reasonable best efforts to file with the SEC the Initial Shelf Registration on
or before the 45th day after the occurrence of any of the events set forth in
Section 2(c) (the "INITIAL SHELF REGISTRATION FILING DATE"). The Initial Shelf
Registration shall be on Form S-1 or another appropriate form permitting
registration of such Registrable Notes for resale by Holders in the manner or
manners reasonably designated by them (including, without limitation, one or
more underwritten offerings). The Company shall not permit any securities other
than the Registrable Notes to be included in the Initial Shelf Registration or
any Subsequent Shelf Registration (as defined below).

                  The Company shall use its reasonable best efforts to cause the
Initial Shelf Registration to be declared effective under the Securities Act on
or prior to the 45th day after the Initial Shelf Registration Filing Date (the
"INITIAL SHELF REGISTRATION EFFECTIVENESS DATE") and to keep the Initial Shelf
Registration continuously effective under the Securities Act until the date
which is the earlier of (a) two years from the Issue Date (the "EFFECTIVENESS
PERIOD"), and (b) such shorter period ending when (i) all Registrable Notes
covered by the Initial Shelf Registration have been sold in the manner set forth
and as contemplated in the Initial Shelf Registration or (ii) a Subsequent Shelf
Registration covering all of the Registrable Notes covered by and not sold under
the Initial Shelf Registration or an earlier Subsequent Shelf Registration has
been declared effective under the Securities Act (the "APPLICABLE PERIOD");
PROVIDED, HOWEVER, that the Effectiveness Period in respect of the Initial Shelf
Registration shall be extended to the extent required to permit dealers to
comply with the applicable prospectus delivery requirements of Rule 174 under
the Securities Act and as otherwise provided herein.

                                       8
<PAGE>

                  (b) SUBSEQUENT SHELF REGISTRATIONS. If the Initial Shelf
Registration or any Subsequent Shelf Registration ceases to be effective for any
reason at any time during the Effectiveness Period (other than because of the
sale of all of the securities registered thereunder), the Company shall use its
reasonable best efforts to obtain the prompt withdrawal of any order suspending
the effectiveness thereof, and in any event shall within 60 days of such
cessation of effectiveness amend the Initial Shelf Registration in a manner to
obtain the withdrawal of the order suspending the effectiveness thereof, or file
an additional "shelf" Registration Statement pursuant to Rule 415 covering all
of the Registrable Notes covered by and not sold under the Initial Shelf
Registration or an earlier Subsequent Shelf Registration (each, a "SUBSEQUENT
SHELF REGISTRATION"). If a Subsequent Shelf Registration is filed, the Company
shall use its reasonable best efforts to cause the Subsequent Shelf Registration
to be declared effective under the Securities Act as soon as practicable after
such filing and to keep such subsequent Shelf Registration continuously
effective for the remainder of the Effectiveness Period. As used herein the term
"SHELF REGISTRATION" means the Initial Shelf Registration and any Subsequent
Shelf Registration.

                  (c) SUPPLEMENTS AND AMENDMENTS. The Company shall promptly
supplement and amend any Shelf Registration if required by the rules,
regulations or instructions applicable to the registration form used for such
Shelf Registration, if required by the Securities Act, or if reasonably
requested by the Holders of a majority in aggregate principal amount of the
Registrable Notes covered by such Registration Statement or by any underwriter
of such Registrable Notes.

                  4. ADDITIONAL INTEREST.

                  (a) The Company and the Initial Purchasers agree that the
Holders will suffer damages if the Company fails to fulfill its obligations
under Section 2 or Section 3 hereof and that it would not be feasible to
ascertain the extent of such damages with precision. Accordingly, the Company
agrees to pay, as liquidated damages, additional interest on the Notes
("ADDITIONAL INTEREST") under the circumstances and to the extent set forth
below (each of which shall be given independent effect):

                  (i) if (A) neither the Exchange Registration Statement nor the
         Initial Shelf Registration has been filed on or prior to the applicable
         Filing Date or (B) notwithstanding that the Company has consummated or
         will consummate the Exchange Offer, the Company is required to file a
         Shelf Registration and such Shelf Registration is not filed on or prior
         to the Filing Date applicable thereto, then commencing on the day after
         any such Filing Date, Additional Interest shall accrue on the principal
         amount of the Notes at a rate of .25% per annum for the first 90 days
         immediately following each such Filing Date, and such Additional
         Interest shall increase by an additional .25% per annum at the
         beginning of each subsequent 90-day period; or

                  (ii) if (A) neither the Exchange Registration Statement nor
         the Initial Shelf Registration is declared effective by the SEC on or
         prior to the relevant Effectiveness Date or (B) notwithstanding that
         the Company has consummated or will consummate the Exchange Offer, the
         Company is required to file a Shelf Registration and such Shelf
         Registration is not declared effective by the SEC on or prior to the
         Effectiveness Date in

                                       9
<PAGE>

         respect of such Shelf Registration, then, commencing on the day after
         the applicable Effectiveness Date, Additional Interest shall accrue on
         the principal amount of the Notes at a rate of .25% per annum for the
         first 90 days immediately following the day after such Effectiveness
         Date, and the rate of such Additional Interest shall increase by an
         additional .25% per annum at the beginning of each subsequent 90-day
         period; or

                  (iii) if (A) the Company has not exchanged Exchange Notes for
         all Notes validly tendered in accordance with the terms of the Exchange
         Offer on or prior to the 120th day after the Issue Date or (B) if
         applicable, a Shelf Registration has been declared effective and such
         Shelf Registration ceases to be effective at any time during the
         Effectiveness Period (other than such time as all Notes have been
         disposed of thereunder), then Additional Interest shall accrue on the
         principal amount of the Notes at a rate of .25% per annum for the first
         90 days commencing on the (x) 120th day after such Issue Date, in the
         case of (A) above, or (y) the day such Shelf Registration ceases to be
         effective in the case of (B) above, such Additional Interest shall
         increase by an additional .25% per annum at the beginning of each such
         subsequent 90-day period (it being understood and agreed that,
         notwithstanding any provision to the contrary, so long as any Note that
         is the subject of a Shelf Notice is then covered by an effective Shelf
         Registration, no Additional Interest shall accrue or accumulate on such
         Notes);

PROVIDED, HOWEVER, that the rate of Additional Interest that shall accrue on the
Notes may not exceed in the aggregate 1.0% per annum; PROVIDED, FURTHER,
HOWEVER, that (1) upon the filing of the applicable Exchange Registration
Statement or the applicable Shelf Registration as required hereunder (in the
case of clause (i) above of this Section 4(a)), (2) upon the effectiveness of
the applicable Exchange Registration Statement or the applicable Shelf
Registration Statement as required hereunder (in the case of clause (ii) of this
Section 4(a)), or (3) upon the exchange of the applicable Exchange Notes for all
Notes validly tendered (in the case of clause (iii) (A) of this Section 4 (a),
or upon the effectiveness of the applicable Shelf Registration Statement which
had ceased to remain effective (in the case of (iii) (B) of this Section 4 (a)),
Additional Interest on the Notes in respect of which such events relate as a
result of such clause (or the relevant subclause thereof), as the case may be,
shall cease to accrue or accumulate, as the case may be.

                  (b) The Company shall notify the Trustee (who shall be acting
under and protected by the terms of the Indenture) within three business days
after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an "EVENT DATE"). Any amounts of
Additional Interest due pursuant to (a) (i), (a) (ii) or (a) (iii) of this
Section 4 shall be payable in cash semiannually on each February 15 and August
15 (to the holders of record as of the close of business on the February 1 and
August 1 immediately preceding such dates), commencing with the first such date
occurring after any such Additional Interest commences to accrue. The amount of
Additional Interest will be determined by multiplying the applicable rate of
Additional Interest by the principal amount of the Registrable Notes, multiplied
by a fraction, the numerator of which is the number of days such rate of
Additional Interest was applicable during such period (determined on the basis
of a 360-day year comprised of twelve 30-day months and, in the case of a
partial month, the actual number of days elapsed), and the denominator of which
is 360.

                  5. REGISTRATION PROCEDURES.

                  In connection with the filing of any Registration Statement
pursuant to Sections 2 or 3 hereof, the Company shall effect such registrations
to permit the sale of the securities covered thereby in accordance with the
intended method or methods of disposition thereof, and pursuant thereto and in
connection with any Registration Statement filed by the Company hereunder, the
Company shall:

                  (a) Prepare and file with the SEC prior to the applicable
Filing Date, a Registration Statement or Registration Statements as prescribed
by Sections 2 or 3 hereof, and use its reasonable best efforts to cause each
such Registration Statement to become effective and remain effective as provided
herein; PROVIDED, HOWEVER, that, if (1) such filing is pursuant to Section 3
hereof, or (2) a Prospectus contained in the Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period relating thereto, before filing any
Registration Statement or Prospectus or any amendments or supplements thereto,
the Company shall furnish to and afford the Holders of the Registrable Notes
included in such Registration Statement or each such Participating
Broker-Dealer, as the case may be, their counsel and the managing underwriters,
if any, a reasonable opportunity to review copies of all such documents
(including copies of any documents to be incorporated by reference therein and
all exhibits thereto) proposed to be filed (in each case at least five days
prior to such filing, or such later date as is reasonable under the
circumstances). The Company shall not file any Registration Statement or
Prospectus or any amendments or supplements thereto if the Holders of a majority
in aggregate principal amount of the Registrable Notes included in such
Registration Statement, or any such Participating Broker-Dealer, as the case may
be, their counsel, or the managing underwriters, if any, shall reasonably object
on a timely basis.

                  (b) Prepare and file with the SEC such amendments and
post-effective amendments to each Shelf Registration Statement or Exchange
Registration Statement, as the case may be, as may be necessary to keep such
Registration Statement continuously effective for the Effectiveness Period or
the Applicable Period, as the case may be; cause the related Prospectus to be
supplemented by any prospectus supplement required by applicable law, and as so
supplemented to be filed pursuant to Rule 424 (or any similar provisions then in
force) promulgated under the Securities Act; and comply with the provisions of
the Securities Act and the Exchange Act applicable to it with respect to the
disposition of all securities covered by such Registration Statement as so
amended or in such Prospectus as so supplemented and with respect to the
subsequent resale of any securities being sold by a Participating Broker-Dealer
covered by any such Prospectus. The Company shall be deemed not to have used its
reasonable best efforts to keep a Registration Statement effective during the
Effectiveness Period or the Applicable Period, as the case may be, relating
thereto if the Company voluntarily takes any action that would result in selling
Holders of the Registrable Notes covered thereby or Participating Broker-Dealers
seeking to sell Exchange Notes not being able to sell such Registrable Notes or
such Exchange Notes during that period unless such action is required by
applicable law or permitted by this Agreement.

                                       11
<PAGE>

                  (c) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period relating thereto from whom the Company has
received written notice that it will be a Participating Broker-Dealer in the
applicable Exchange Offer, notify the selling Holders of Registrable Notes or
each such Participating Broker-Dealer, as the case may be, their counsel and the
managing underwriters, if any, promptly (but in any event within 2 business
days), and confirm such notice in writing, (i) when a Prospectus or any
Prospectus supplement or post-effective amendment has been filed, and, with
respect to a Registration Statement or any post-effective amendment, when the
same has become effective under the Securities Act (including in such notice a
written statement that any Holder may, upon request, obtain, at the sole expense
of the Company, one conformed copy of such Registration Statement or
post-effective amendment including financial statements and schedules, documents
incorporated or deemed to be incorporated by reference and exhibits), (ii) of
the issuance by the SEC of any stop order suspending the effectiveness of a
Registration Statement or of any order preventing or suspending the use of any
preliminary prospectus or the initiation of any proceedings for that purpose,
(iii) if at any time when a prospectus is required by the Securities Act to be
delivered in connection with sales of the Registrable Notes or resales of
Exchange Notes by Participating Broker-Dealers the representations and
warranties of the Company contained in any agreement (including any underwriting
agreement) contemplated by Section 5(1) hereof cease to be true and correct in
all material respects, (iv) of the receipt by the Company of any notification
with respect to the suspension of the qualification or exemption from
qualification of a Registration Statement or any of the Registrable Notes or the
Exchange Notes to be sold by any Participating Broker-Dealer for offer or sale
in any jurisdiction, or the initiation or written threat of any proceeding for
such purpose, (v) of the happening of any event, the existence of any condition
or any information becoming known that makes any statement made in such
Registration Statement or related Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires the making of any changes in or amendments or supplements to such
Registration Statement, Prospectus or documents so that, in the case of the
Registration Statement, it will not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and that in the case of
the Prospectus, it will not contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, and (vi) of the Company's determination that a
post-effective amendment to a Registration Statement would be appropriate.

                  (d) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, use its reasonable best efforts to prevent
the issuance of any order suspending the effectiveness of a Registration
Statement or of any order preventing or suspending the use of a Prospectus or
suspending the qualification (or exemption from qualification) of any of the
Registrable Notes or the Exchange Notes to be sold by any Participating
Broker-Dealer, for sale in any jurisdiction, and, if any such order is issued,
to use its best efforts to obtain the withdrawal of any such order at the
earliest possible moment.

<PAGE>

                  (e) If a Shelf Registration is filed pursuant to Section 3 and
if reasonably requested by the managing underwriter or underwriters (if any),
the Holders of a majority in aggregate principal amount of the Registrable Notes
being sold in connection with an underwritten offering (i) as promptly as
practicable incorporate in a prospectus supplement or post-effective amendment
such information as the managing underwriter or underwriters (if any), such
Holders, or counsel for any of them determine is reasonably necessary to be
included therein, (ii) make all required filings of such prospectus supplement
or such post-effective amendment as soon as practicable after the Company have
received notification of the matters to be incorporated in such prospectus
supplement or post-effective amendment, and (iii) supplement or make amendments
to such Registration Statement.

                  (f) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, furnish to each selling Holder of
Registrable Notes and to each such Participating Broker-Dealer who so reasonably
requests and to their respective counsel and each managing underwriter, if any,
at the sole expense of the Company, one conformed copy of the Registration
Statement or Registration Statements and each post-effective amendment thereto,
including financial statements and schedules, and, if reasonably requested, all
documents incorporated or deemed to be incorporated therein by reference and all
exhibits.

                  (g) If (1) a Shelf Registration is filed pursuant to Section 3
hereof, or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 hereof is required to be delivered under the
Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, deliver to each selling Holder of
Registrable Notes or each such Participating Broker-Dealer, as the case may be,
their respective counsel, and the underwriters, if any, at the sole expense of
the Company, as many copies of the Prospectus or Prospectuses (including each
form of preliminary prospectus) and each amendment or supplement thereto and any
documents incorporated by reference therein as such Persons may reasonably
request; and, subject to the last paragraph of this Section 5, the Company
hereby consents to the use of such Prospectus and each amendment or supplement
thereto by each of the selling Holders of Registrable Notes or each such
Participating Broker-Dealer, as the case may be, and the underwriters or agents,
if any, and dealers (if any), in connection with the offering and sale of the
Registrable Notes covered by, or the sale by Participating Broker-Dealers of the
Exchange Notes pursuant to, such Prospectus and any amendment or supplement
thereto.

                  (h) Prior to any public offering of Registrable Notes or
any delivery of a Prospectus contained in the Exchange Registration Statement by
any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period, use its reasonable best efforts to register or qualify, and
to cooperate with the selling Holders of Registrable Notes or each such
Participating Broker-Dealer, as the case may be, the managing underwriter or
underwriters, if any, and their respective counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Notes for offer and sale under the securities
or Blue Sky laws of such jurisdictions within the United States as any selling
Holder, Participating Broker-Dealer, or the managing underwriter or underwriters
reasonably



                                       13
<PAGE>

request in writing; PROVIDED, HOWEVER, that where Exchange Notes held by
Participating Broker-Dealers or Registrable Notes are offered other than through
an underwritten offering, the Company agrees to cause their counsel to perform
Blue Sky investigations and file registrations and qualifications required to be
filed pursuant to this Section 5(h), keep each such registration or
qualification (or exemption therefrom) effective during the period such
Registration Statement is required to be kept effective and do any and all other
acts or things reasonably necessary or advisable to enable the disposition in
such jurisdictions of the Exchange held by Participating Broker-Dealers or the
Registrable Notes covered by the Registration Statement; PROVIDED, HOWEVER, that
the Company shall not be required to (A) qualify generally to do business in any
jurisdiction where it is not then so qualified, (B) take any action that would
subject it to general service of process in any such jurisdiction where it is
not then so subject or (C) subject itself to taxation in excess of a nominal
dollar amount in any such jurisdiction where it is not then so subject.

                  (i) If a Shelf Registration is filed pursuant to Section
3 hereof, cooperate with the selling Holders of Registrable Notes and the
managing underwriter or underwriters, if any, to facilitate the timely
preparation and delivery of certificates representing Registrable Notes to be
sold, which certificates shall not bear any restrictive legends and shall be in
a form eligible for deposit with The Depository Trust Company; and enable such
Registrable Notes to be in such denominations and registered in such names as
the managing underwriter or underwriters, if any, or Holders may reasonably
request.

                  (j) If (1) a Shelf Registration is filed pursuant to
Section 3 hereof, or (2) a Prospectus contained in the Exchange Registration
Statement filed pursuant to Section 2 hereof is required to be delivered under
the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, upon the occurrence of any event
contemplated by paragraph 5(c) (v) or 5(c) (vi) hereof, as promptly as
practicable prepare and (subject to Section 5(a) hereof) file with the SEC, at
the sole expense of the Company, a supplement or post-effective amendment to the
applicable Registration Statement or a supplement to the related Prospectus or
any document incorporated or deemed to be incorporated therein by reference, or
file any other required document so that, as thereafter delivered to the
purchasers of the Registrable Notes being sold thereunder or to the purchasers
of the Exchange Notes to whom such Prospectus will be delivered by a
Participating Broker-Dealer, any such Prospectus will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading. Notwithstanding the
foregoing, the Company shall not be required to amend or supplement a
Registration Statement, any related Prospectus or any document incorporated
therein by reference, in the event that, and for a period not to exceed an
aggregate of 90 days in any calendar year if, (i) an event occurs and is
continuing as a result of which a Shelf Registration would, in the Company's
good faith judgment, contain an 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, and (ii)
(a) the Company determines in its good faith judgment that the disclosure of
such event at such time would have a material adverse effect on the business,
operations or prospects of the Company or (b) the disclosure otherwise relates
to a pending material business transaction that has not yet been publicly
disclosed.

<PAGE>

                  (k) Prior to the effective date of the first Registration
Statement relating to the Registrable Notes, (i) provide the Trustee with
certificates for the Registrable Notes in a form eligible for deposit with The
Depository Trust Company and (ii) provide a CUSIP number for the Registrable
Notes.

                  (1) In the case of a Shelf Registration, enter into such
agreements (including underwriting agreements) and take all such other
appropriate actions as are reasonably requested in order to expedite or
facilitate the registration or the disposition of such Registrable Notes, and in
such connection, (i) make such representations and warranties to Holders of such
Registrable Notes with respect to the business of the Company and its
subsidiaries as then conducted and the Registration Statement, Prospectus and
documents, if any, incorporated or deemed to be incorporated by reference
therein, in each case, as are customarily made by Company to underwriters in
underwritten offerings, and confirm the same if and when requested; (ii) obtain
opinions of counsel to the Company and updates thereof in form and substance
reasonably satisfactory to the Holders of a majority in principal amount of the
Registrable Notes being sold, addressed to each selling Holder covering the
matters customarily covered in opinions requested in underwritten offerings and
such other matters as may be reasonably requested by such Holders; (iii) obtain
"cold comfort" letters and updates thereof from the independent certified public
accountants of the Company (and, if necessary, any other independent certified
public accountants of any subsidiary of the Company or of any business acquired
by the Company for which financial statements and financial data are, or are
required to be, included in the Registration Statement), addressed to the
selling Holders of Registrable Notes that satisfy the applicable requirements of
Statement of Accounting Standards No. 72, such letters to be in customary form
and covering matters of the type customarily covered in "cold comfort" letters
in connection with underwritten offerings and such other matters as reasonably
requested by such selling Holders; and (iv) if an underwriting agreement is
entered into, the same shall contain indemnification provisions and procedures
no less favorable than those set forth in Section 7 hereof (or such other
provisions and procedures acceptable to the Company and the Holders of a
majority in aggregate principal amount of Registrable Notes covered by such
Registration with respect to all parties to be indemnified pursuant to said
Section including, without limitation, such selling Holders). The above shall be
done at each closing in respect of the sale of Registrable Notes, or as and to
the extent required thereunder.

                  (m) If (1) a Shelf Registration is filed pursuant to
Section 3 hereof, or (2) a Prospectus contained in an Exchange Registration
Statement filed pursuant to Section 2 hereof is required to be delivered under
the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange
Notes during the Applicable Period, make available for inspection by any selling
Holder of such Registrable Notes being sold, or each such Participating
Broker-Dealer, as the case may be, any underwriter participating in any such
disposition of Registrable Notes, if any, and any attorney, accountant or other
agent retained by any such selling Holder or each such Participating
Broker-Dealer, as the case may be, or underwriter (collectively, the
"INSPECTORS"), at the offices where normally kept, during reasonable business
hours, all financial and other records, pertinent corporate documents and
instruments of the Company and subsidiaries of the Company (collectively, the
"RECORDS") as shall be reasonably necessary to enable them to exercise any
applicable due diligence responsibilities, and cause the officers, directors and
employees of the Company and any of its subsidiaries to supply all information
reasonably requested by any such Inspector in connection with such Registration
Statement and Prospectus.



                                       15
<PAGE>

Each Inspector shall agree in writing that it will keep the Records confidential
and that it will not disclose any of the Records that the Company determines, in
good faith, to be confidential and notify the Inspectors in writing are
confidential unless (i) the disclosure of such Records is necessary to avoid or
correct a material misstatement or material omission in such Registration
Statement or Prospectus, (ii) the release of such Records is ordered pursuant to
a subpoena or other order from a court of competent jurisdiction, or (iii) the
information in such Records has been made generally available to the public;
provided, however, that prior notice shall be provided as soon as practicable to
the Company of the potential disclosure of any information by such Inspector
pursuant to clauses (i) or (ii) of this sentence to permit the Company to obtain
a protective order (or waive the provisions of this paragraph (m)) and that such
Inspector shall take such actions as are reasonably necessary to protect the
confidentiality of such information (if practicable) to the extent such action
is otherwise not inconsistent with, an impairment of or in derogation of the
rights and interests of the Holder or any Inspector.

                  (n) Provide an indenture trustee for the Registrable
Notes or the Exchange Notes, as the case may be, and cause the Indenture or the
trust indenture provided for in Section 2 (a) hereof, as the case may be, to be
qualified under the TIA not later than the effective date of the first
Registration Statement relating to the Registrable Notes; and in connection
therewith, cooperate with the trustee under any such indenture and the Holders
of the Registrable Notes, to effect such changes to such indenture as may be
required for such indenture to be so qualified in accordance with the terms of
the TIA; and execute, and use their best efforts to cause such trustee to
execute, all documents as may be required to effect such changes, and all other
forms and documents required to be filed with the SEC to enable such indenture
to be so qualified in a timely manner.

                  (o) Comply with all applicable rules and regulations of
the SEC and make generally available to their securityholders with regard to any
applicable Registration Statement, a consolidated earning statement satisfying
the provisions of Section 11 (a) of the Securities Act and Rule 158 thereunder
(or any similar rule promulgated under the Securities Act) no later than 45 days
after the end of any twelve-month period (or 90 days after the end of any
12-month period if such period is a fiscal year) (i) commencing at the end of
any fiscal quarter in which any Registrable Notes are sold to underwriters in a
firm commitment or best efforts underwritten offering and (ii) if not sold to
underwriters in such an offering, commencing on the first day of the first
fiscal quarter of the Company after the effective date of a Registration
Statement, which statements shall cover said 12-month periods.

                  (p) Upon consummation of an Exchange Offer or a Private
Exchange, obtain an opinion of counsel to the Company addressed to the Trustee
for the benefit of all Holders of Registrable Notes participating in the
Exchange Offer or Private Exchange, as the case may be, that the Exchange Notes
or Private Exchange Notes as the case may be, and the related indenture
constitute legal, valid and binding obligations of the Company, enforceable
against it in accordance with their respective terms subject to customary
exceptions and qualifications.

                  (q) If the Exchange Offer or a Private Exchange is to be
consummated, upon delivery of the Registrable Notes by Holders to the Company
(or to such other Person as directed by the Company) in exchange for the
Exchange Notes or the Private Exchange Notes, as the case may be, the Company
shall mark, or cause to be marked, on such Registrable Notes that such

                                       16
<PAGE>

Registrable Notes are being canceled in exchange for the Exchange Notes or the
Private Exchange Notes, as the case may be; PROVIDED that in no event shall such
Registrable Notes be marked as paid or otherwise satisfied.

                  (r) Cooperate with each seller of Registrable Notes
covered by any Registration Statement and each underwriter, if any,
participating in the disposition of such Registrable Notes and their respective
counsel in connection with any filings required to be made with the National
Association of Securities Dealers, Inc. (the "NASD").

                  (s) Use their best efforts to take all other steps
reasonably necessary to effect the registration of the applicable Registrable
Notes covered by a Registration Statement contemplated hereby.

                  The Company may require each seller of any Registrable Notes
as to which any registration is being effected to furnish to the Company such
information regarding such seller and the distribution of such Registrable Notes
as the Company may, from time to time, reasonably request. The Company may
exclude from such registration the Registrable Notes of any seller for so long
as such seller fails to furnish such information within a reasonable time after
receiving such request and in such event shall have no further obligation under
this Agreement (including without limitation the obligation under Section 4)
with respect to such seller or any subsequent holder of such Registrable Notes.
Each seller as to which any Shelf Registration is being effected agrees to
furnish promptly to the Company all information required to be disclosed in
order to make the information previously furnished to the Company by such seller
not materially misleading.

                  If any such Registration Statement refers to any Holder by
name or otherwise as the holder of any securities of the Company, then such
Holder shall have the right to require (i) the insertion therein of language, in
form and substance reasonably satisfactory to such Holder, to the effect that
the holding by such Holder of such securities is not to be construed as a
recommendation by such Holder of the investment quality of the securities
covered thereby and that such holding does not imply that such Holder will
assist in meeting any future financial requirements of the Company, or (ii) in
the event that such reference to such Holder by name or otherwise is not
required by the Securities Act or any similar federal statute then in force, the
deletion of the reference to such Holder in any amendment or supplement to the
applicable Registration Statement filed or prepared subsequent to the time that
such reference ceases to be required.

                  Each Holder of Registrable Notes and each Participating
Broker-Dealer agrees by its acquisition of such Registrable Notes or Exchange
Notes, as the case may be, to be sold by such Participating Broker-Dealer, as
the case may be, that, upon actual receipt of any notice from the Company of the
happening of any event of the kind described in Section 5 (c) (ii), 5 (c) (iv),
5(c) (v), or 5(c) (vi) hereof, such Holder or Participating Broker-Dealer, as
the case may be, will forthwith discontinue disposition of such Registrable
Notes or Exchange Notes, as the case may be, covered by such Registration
Statement or Prospectus until such Holder's or Participating Broker-Dealer's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 5(j) hereof, or until it is advised in writing (the "ADVICE") by the
Company that the use of the applicable Prospectus may be resumed, and has
received copies of any amendments or



                                       17
<PAGE>

supplements thereto. In the event that the Company shall give any such notice,
the Applicable Period shall be extended by the number of days during such
periods from and including the date of the giving of such notice to and
including the date when each seller of Registrable Notes covered by such
Registration Statement or Exchange Notes to be sold by such Participating
Broker-Dealer, as the case may be, shall have received (x) the copies of the
supplemented or amended Prospectus contemplated by Section 5(j) hereof or (y)
the Advice.

                  6. REGISTRATION EXPENSES.

                  All fees and expenses incident to the performance of or
compliance with this Agreement by the Company (other than any underwriting
discounts or commissions) shall be borne by the Company whether or not the
Exchange Registration Statement or any Shelf Registration is filed or becomes
effective or the Exchange Offer is consummated, including, without limitation,
(i) all registration and filing fees (including, without limitation, (A) fees
with respect to filings required to be made with the NASD in connection with an
underwritten offering and (B) fees and expenses of compliance with state
securities or Blue Sky laws (including, without limitation, reasonable fees and
disbursements of counsel in connection with Blue Sky qualifications of the
Registrable Notes or Exchange Notes and determination of the eligibility of the
Registrable Notes or Exchange Notes for investment under the laws of such
jurisdictions (x) where the holders of Registrable Notes or Exchange Notes, as

                  7. INDEMNIFICATION AND CONTRIBUTION.

                  (a) The Company agrees to indemnify and hold harmless
each Holder of the Registrable Notes and each Participating Broker-Dealer
selling the Exchange Notes during the



                                       18
<PAGE>

Applicable Period, the affiliates, officers and directors of each such Person,
and each Person, if any, who controls any such Person within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act (each,
a "PARTICIPANT"), from and against any and all losses, claims, damages,
judgments, liabilities and expenses (including, without limitation, the
reasonable legal fees and other expenses actually incurred in connection with
any suit, action or proceeding or any claim asserted) caused by, arising out of
or based upon any untrue statement or alleged untrue statement of a material
fact contained in any Registration Statement (or any amendment thereto) or
Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto) or any preliminary prospectus, or caused by,
arising out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in the case of the Prospectus in the light of the circumstances under
which they were made, not misleading, except insofar as such losses, claims,
damages or liabilities are caused by any untrue statement or omission or alleged
untrue statement or omission made in reliance upon and in conformity with
information relating to any Participant furnished to the Company in writing by
such Participant expressly for use therein and with respect to any preliminary
Prospectus, to the extent that any such loss, claim, damage or liability arises
solely from the fact that any Participant sold Registrable Notes or Exchange
Notes to a person to whom there was not sent or given a copy of the Prospectus
(as amended or supplemented) at or prior to the written confirmation of such
sale if the Company shall have previously furnished copies thereof to the
Participant in accordance herewith and the Prospectus (as amended or
supplemented) would have corrected any such untrue statement or omission.

                  (b) Each Participant agrees, severally and not jointly,
to indemnify and hold harmless the Company, the affiliates, officers and
directors of the Company and each Person who controls the Company within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent (but on a several, and not joint, basis) as the foregoing
indemnity from the Company to each Participant, but only with reference to
information relating to such Participant furnished to the Company in writing by
or on behalf of such Participant expressly for use in any Registration Statement
or Prospectus, any amendment or supplement thereto, or any preliminary
prospectus. The liability of any Participant under this paragraph shall in no
event exceed the proceeds received by such Participant from sales of Registrable
Notes or Exchange Notes giving rise to such obligations.

                  (c) If any suit, action, proceeding (including any
governmental or regulatory investigation), claim or demand shall be brought or
asserted against any Person in respect of which indemnity may be sought pursuant
to either of the two preceding paragraphs, such Person (the "INDEMNIFIED
PERSON") shall promptly notify the Persons against whom such indemnity may be
sought (the "INDEMNIFYING PERSONS") in writing, and the Indemnifying Persons,
upon request of the Indemnified Person, shall retain counsel reasonably
satisfactory to the Indemnified Person to represent the Indemnified Person and
any others the Indemnifying Persons may reasonably designate in such proceeding
and shall pay the reasonable fees and expenses actually incurred by such counsel
related to such proceeding; PROVIDED, HOWEVER, that the failure to so notify the
Indemnifying Persons will not relieve it from any liability under paragraph (a)
or (b) above unless and to the extent such failure results in the forfeiture by
the Indemnifying Person of substantial rights and defenses and the Indemnifying
Person was not otherwise aware of such action or claim. In any such proceeding,
any Indemnified Person shall have the right to retain its



                                       19
<PAGE>

own counsel, but the fees and expenses of such counsel shall be at the expense
of such Indemnified Person unless (i) the Indemnifying Persons and the
Indemnified Person shall have mutually agreed to the contrary, (ii) the
Indemnifying Persons shall have failed within a reasonable period of time to
retain counsel reasonably satisfactory to the Indemnified Person or (iii) the
named parties in any such proceeding (including any impleaded parties) include
both any Indemnifying Person and the Indemnified Person or any affiliate thereof
and representation of both parties by the same counsel would be inappropriate
due to actual or potential differing interests between them. It is understood
that the Indemnifying Persons shall not, in connection with such proceeding or
separate but substantially similar related proceedings in the same jurisdiction
arising out of the same general allegations, be liable for the reasonable fees
and expenses of more than one separate firm (in addition to any local counsel)
for all Indemnified Persons, and that all such fees and expenses shall be
reimbursed promptly as they are incurred. Any such separate firm for the
Participants and such control Persons of Participants shall be designated in
writing by Participants who sold a majority in interest of Registrable Notes and
Exchange Notes sold by all such Participants and shall be reasonably acceptable
to the Company, and any such separate firm for the Company, their affiliates,
officers, directors, representatives, employees and agents and such control
Persons of such Company shall be designated in writing by such Company and shall
be reasonably acceptable to the Holders.

                  The Indemnifying Persons shall not be liable for any
settlement of any proceeding effected without its prior written consent (which
consent shall not be unreasonably withheld or delayed), but if settled with such
consent or if there be a final non-appealable judgment for the plaintiff for
which the Indemnified Person is entitled to indemnification pursuant to this
Agreement, each of the Indemnifying Persons agrees to indemnify and hold
harmless each Indemnified Person from and against any loss or liability by
reason of such settlement or judgment. No Indemnifying Person shall, without the
prior written consent of the Indemnified Persons (which consent shall not be
unreasonably withheld or delayed), effect any settlement or compromise of any
pending or threatened proceeding in respect of which any Indemnified Person is
or could have been a party to such proceeding, or indemnity could have been
sought hereunder by such Indemnified Person, unless such settlement (A) includes
an unconditional written release of such Indemnified Person, in form and
substance reasonably satisfactory to such Indemnified Person, from all liability
on claims that are the subject matter of such proceeding and (B) does not
include any statement as to an admission of fault, culpability or failure to act
by or on behalf of such Indemnified Person.

                  (d) If the indemnification provided for in the first and
second paragraphs of this Section 7 is for any reason unavailable to, or
insufficient to hold harmless, an Indemnified Person in respect of any losses,
claims, damages or liabilities referred to therein, then each Indemnifying
Person under such paragraphs, in lieu of indemnifying such Indemnified Person
thereunder and in order to provide for just and equitable contribution, shall
contribute to the amount paid or payable by such Indemnified Person as a result
of such losses, claims, damages or liabilities in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Person or Persons
on the one hand and the Indemnified Person or Persons on the other in connection
with the statements or omissions or alleged statements or omissions that
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof) as well as any other relevant equitable considerations. The relative
fault of the parties shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material



                                       20
<PAGE>

fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or such Participant or such
other Indemnified Person, as the case may be, on the other, the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission, and any other equitable considerations
appropriate in the circumstances.

                  (e) The parties agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by PRO RATA
allocation (even if the Participants were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Person as a result of the losses,
claims, damages, judgments, liabilities and expenses referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any reasonable legal or other expenses actually
incurred by such Indemnified Person in connection with investigating or
defending any such action or claim. Notwithstanding the provisions of this
Section 7, in no event shall a Participant be required to contribute any amount
in excess of the amount by which proceeds received by such Participant from
sales of Registrable Notes or Exchange Notes, as the case may be, exceeds the
amount of any damages that such Participant has otherwise been required to pay
or has paid by reason of such untrue or alleged untrue statement or omission or
alleged omission. No Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

                  (f) The indemnity and contribution agreements contained
in this Section 7 will be in addition to any liability that the Indemnifying
Persons may otherwise have to the Indemnified Persons referred to above.

                  8. RULES 144 AND 144A.

                  The Company covenants and agrees, for so long as any
Registrable Notes remain outstanding, that they will file the reports required
to be filed by it under the Securities Act and the Exchange Act and the rules
and regulations adopted by the SEC thereunder in a timely manner in accordance
with the requirements of the Securities Act and the Exchange Act and, if at any
time the Company is not required to file such reports, the Company will, upon
the request of any Holder or beneficial owner of Registrable Notes, make
available such information necessary to permit sales pursuant to Rule 144A under
the Securities Act. The Company further covenants and agrees, for so long as any
Registrable Notes remain outstanding that it will take such further action as
any Holder of Registrable Notes may reasonably request, all to the extent
required from time to time to enable such holder to sell Registrable Notes
without registration under the Securities Act within the limitation of the
exemptions provided by (a) Rule 144(k) and Rule 144A under the Securities Act,
as such Rules may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the SEC.

                  9. MISCELLANEOUS.

                  (a) NO INCONSISTENT AGREEMENTS. The Company has not, as
of the date hereof, and the Company shall not, after the date of this Agreement,
enter into any agreement with



                                       21
<PAGE>

respect to any of their securities that is inconsistent with the rights granted
to the Holders of Registrable Notes in this Agreement or otherwise conflicts
with the provisions hereof. The rights granted to the Holders hereunder do not
in any way conflict with and are not inconsistent with the rights granted to the
holders of the Company's other issued and outstanding securities under any such
agreements. The Company will not enter into any agreement with respect to any of
their securities which will grant to any Person piggy-back registration rights
with respect to any Registration Statement.

                  (b) ADJUSTMENTS AFFECTING REGISTRABLE NOTES. The Company
shall not, directly or indirectly, take any action with respect to the
Registrable Notes that would adversely affect the ability of the Holders of
Registrable Notes to include such Registrable Notes in a registration undertaken
pursuant to this Agreement.

                  (c) AMENDMENTS AND WAIVERS. The provisions of this
Agreement may not be amended, modified or supplemented, and waivers or consents
to departures from the provisions hereof may not be given, otherwise than with
the prior written consent of (I) the Company and (II) (A) the Holders of not
less than a majority in aggregate principal amount of the then outstanding
Registrable Notes and (B) in circumstances that would adversely affect the
Participating Broker-Dealers, the Participating Broker-Dealers holding not less
than a majority in aggregate principal amount of the Exchange Notes held by all
Participating Broker-Dealers; PROVIDED, HOWEVER, that Section 7 and this Section
10(c) may not be amended, modified or supplemented without the prior written
consent of each Holder and each Participating Broker-Dealer (including any
person who was a Holder or Participating Broker-Dealer of Registrable Notes or
Exchange Notes, as the case may be, disposed of pursuant to any Registration
Statement) affected by any such amendment, modification or supplement.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders of Registrable Notes whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect, impair,
limit or compromise the rights of other Holders of Registrable Notes may be
given by Holders of at least a majority in aggregate principal amount of the
Registrable Notes being sold pursuant to such Registration Statement.

                  (d) NOTICES. All notices and other communications
(including, without limitation, any notices or other communications to the
Trustee) provided for or permitted hereunder shall be made in writing by

                  (f) COUNTERPARTS. This Agreement may be executed in any
number of counterparts and by the parties hereto in separate counterparts, each

SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION
OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

                  (i) SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties

given by the Holders of such required percentage.

Notes, and Participating Broker-Dealers are intended third-party beneficiaries
of this Agreement, and this Agreement may be enforced by such Persons.

                             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) Steven C. Berger, Robert W. Keelips, III and Paul A. Redmond
(collectively, the "RETIRING MEMBERS"). The Exchanging Members and the Retiring
Members 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 Stockholders have entered into an
Exchange Agreement, dated as of June 15, 1999 (the "EXCHANGE AGREEMENT"),
pursuant to which (i) 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 and (ii)
the Retiring Members have agreed to contribute their respective membership
interests in Investing to the Company in exchange for 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 and the 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");

         WHEREAS, it is a condition under the Exchange Agreement that the
parties hereto enter into this Agreement.

         "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


                                        3

<PAGE>


         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 persons listed on Schedule I 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

         Section 1.8.   CERTIFICATES TO BE HELD BY COMPANY. (a) Each Exchanging
Member 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 Exchanging Member or the estate of any
Exchanging Member, 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 Exchanging Member 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 Exchanging Member's
Covered Securities which are then intended and permitted to be Transferred under
the provisions of this Agreement.

                   (b)  Subject to the Exchanging Members 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 Exchanging
Members 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 Exchanging Member 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
Exchanging Members.

securities received or resulting therefrom, but only to the extent such
securities are received in exchange for or in respect of Covered Securities.
Upon the occurrence of any event described in the immediately preceding
sentence, the Board of Directors shall make such adjustments to or
interpretations of the restrictions of Section 1.1 (and, if it so determines,
any other provisions hereof) as it shall deem necessary or desirable to carry
out the intent of such provision(s). If the Board of Directors deems it
desirable, any such adjustments may take effect from the record date, the "when
issued trading date," the "ex dividend date" or another appropriate date.

                   (b)  In the event of any business combination, restructuring,
recapitalization or other extraordinary transaction involving any member of the

shall refer to such voting securities formerly representing or distributed in

of Section 1.1 (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.

         Section 5.8.   DISINTERESTED BOARD MEMBERS TO MAKE DETERMINATIONS. In
the event that any Stockholder breaches its obligations under this Agreement,
then the Board of Directors shall have the exclusive right to make (on behalf of
the Company) any and all determinations that may be necessary or appropriate
under this Agreement, including without limitation, determinations relating to
the exercise and enforcement of remedies hereunder. If a Stockholder who is also
a member of the Board of Directors breaches his or her obligations under this
Agreement, such Stockholder must refrain from exercising his or her vote at
meetings of the Board of Directors and general meetings of the Company to give
effect to this Section 5.8.

         Section 5.9.   SEVERABILITY. If the final determination of a court of
competent jurisdiction declares, after the expiration of the time within which
judicial review (if permitted) of such determination may be perfected, that any
term or provision hereof is invalid or unenforceable, (a) the remaining terms
and provisions hereof shall be unimpaired and (b) the invalid or unenforceable
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.

                                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
entirely 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 of

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 reasonable 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 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 EXECTUED 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.

(as defined below), references to the "COMPANY" shall be deemed to be references
to LaBranche & Co., a New York limited partnership ("LABCO."), and after

                  The Company wishes to confirm as follows its agreement with
the Initial Purchasers in connection with the purchase and resale of the Notes.

                  1. PRELIMINARY OFFERING MEMORANDUM AND OFFERING MEMORANDUM.
The Notes will be offered and sold to the Initial Purchasers without
registration under the Securities Act of 1933, as amended (the "ACT"), in
reliance on an exemption pursuant to Section 4(2) under the Act and the rules
and regulations promulgated thereunder. The Company has prepared a preliminary
offering memorandum, dated July 30, 1999 (the "PRELIMINARY OFFERING
MEMORANDUM"), and an offering memorandum, dated August 19, 1999 (the "OFFERING
MEMORANDUM"), setting forth information regarding the Company and the Notes.
Unless stated herein to the contrary, all references herein to the Offering
Memorandum are to the Offering Memorandum at the date thereof and are not meant
to include any supplement or amendment subsequent thereto. The Company hereby
confirms that it has authorized the use of the Preliminary Offering Memorandum
and Offering Memorandum in connection with the offering and resale of the Notes
by the Initial Purchasers on the terms and subject to the conditions set forth
herein.

                  The Company understands that the Initial Purchasers propose to
make offers and sales ("EXEMPT RESALES") of the Notes purchased by the Initial
Purchasers hereunder only on the terms and in the manner set forth in the
Offering Memorandum and Section 2 hereof, as soon as the Initial Purchasers deem
advisable after this Agreement has been executed and delivered, (i) to persons
in the United States who are, or whom the Initial Purchasers reasonably believe
to be, qualified institutional buyers ("QUALIFIED INSTITUTIONAL BUYERS") as
defined in Rule 144A under the Act, as such rule may be amended from time to
time ("RULE 144A"), in transactions under Rule 144A and (ii) outside the United
States to persons other than U.S. persons in reliance upon and in compliance
with Regulation S under the Act, as such regulation may be amended from time to
time ("Regulation S"). The persons specified in clauses (i) and (ii) are
referred to herein as the "ELIGIBLE Purchasers." As used herein, the terms
"UNITED STATES" and "U.S. PERSONS" have the respective meanings given them in
Regulation S.

                  It is understood and acknowledged that upon original issuance
thereof, and until such time as the same is no longer required under the
applicable requirements of the Act, each of the Notes (and each note issued in
exchange therefor or in substitution thereof) shall bear the following legend:

         THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
         AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR
         SOLD EXCEPT AS SET FORTH BELOW. BY ITS ACQUISITION HEREOF, THE HOLDER
         (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL BUYER" (AS
         DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S.
         PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION, (2)
         AGREES THAT IT WILL NOT, WITHIN TWO YEARS AFTER THE ORIGINAL ISSUANCE
         OF THIS SECURITY, RESELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A)
         TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES
         TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER
         THE SECURITIES ACT, (C) OUTSIDE THE UNITED STATES TO PERSONS OTHER THAN
         U.S. PERSONS IN OFFSHORE TRANSACTIONS MEETING THE REQUIREMENTS OF RULE
         904 UNDER REGULATION S UNDER THE SECURITIES ACT, (D) PURSUANT TO THE
         EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES
         ACT (IF AVAILABLE) OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO
         EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY
         TO THE EFFECT OF THIS LEGEND. AS USED HEREIN, THE TERMS "OFFSHORE
         TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE RESPECTIVE
         MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

                  2.       AGREEMENTS TO SELL, PURCHASE AND RESELL.

                  (a) Upon the basis of the representations, warranties and

(A) any advertisement, article, notice or other communication published in any
newspaper, magazine or similar media or broadcast over television or radio, or
(B) any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising; PROVIDED, HOWEVER, that such limitation

affiliates or any persons acting on its behalf or on behalf of its affiliates
has engaged or will engage in any directed selling efforts in the United States

         be offered and sold within the United States or to, or for the account
         or benefit of, U.S. persons (i) as part of their initial distribution

         the Initial Purchasers to Eligible Purchasers, the Company will advise
         the Initial Purchasers



                                       5
<PAGE>



         promptly and, if requested, will confirm such advice in writing, of any
         material adverse change in the condition (financial or other),
         business, prospects, properties, net worth or results of operations of
         the Company, taken as a whole, or of the happening of any event or the
         existence of any condition that requires any amendment or supplement to
         the Offering Memorandum (as then amended or supplemented) so that the
         Offering Memorandum (x) will not contain any untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein, in the light of
         the circumstances under which they were made, not misleading, or (y)
         will comply with applicable law.

                  (b) The Company will furnish to the Initial Purchasers,
         without charge, such number of copies of the Offering Memorandum, as it
         may then be amended or supplemented, as the Initial Purchasers may
         reasonably request.

                  (c) The Company will not make any amendment or supplement to
         the Preliminary Offering Memorandum or to the Offering Memorandum of
         which the Initial Purchasers shall not previously have been advised or
         to which they shall reasonably object in writing after being so advised
         unless, in the opinion of counsel to the Company, such amendment or
         supplement is necessary to comply with applicable law.

                  (d) Prior to the execution and delivery of this Agreement, the
         Company has delivered or will deliver to the Initial Purchasers,
         without charge, in such reasonable quantities as the Initial Purchasers
         shall have requested or may hereafter request, copies of the
         Preliminary Offering Memorandum. The Company consents to the use, in
         accordance with the securities or Blue Sky laws of the jurisdictions in
         which the Notes are offered by the Initial Purchasers and by dealers,
         prior to the date of the Offering Memorandum, of each Preliminary
         Offering Memorandum so furnished by the Company. The Company consents
         to the use of the Offering Memorandum (and of any amendment or
         supplement thereto prepared in accordance with Section 4(c)) in
         accordance with the securities or Blue Sky laws of the jurisdictions in
         which the Notes are offered by the Initial Purchasers and by all
         dealers to whom Notes may be sold, in connection with the offering and
         sale of the Notes.

                  (e) If, at any time prior to completion of the distribution of
         the Notes by the Initial Purchasers to Eligible Purchasers, any event
         shall occur or condition shall exist that in the judgment of the
         Company or in the opinion of the Initial Purchasers based on advice of
         counsel requires any amendment or supplement to the Offering Memorandum
         (as then amended or supplemented) so that the Offering Memorandum (x)
         will not contain any untrue statement of a material fact or omit to
         state a material fact required to be stated therein or necessary to
         make the statements therein, in the light of the circumstances under
         which they were made, not misleading, or (y) will comply with
         applicable law, the Company will, in each such case subject to Section
         4(c), forthwith prepare an appropriate supplement or amendment thereto,
         and will expeditiously furnish to the Initial Purchasers that number of
         copies thereof as they shall reasonably request.



                                       6
<PAGE>


                  (f) The Company will cooperate with the Initial Purchasers and
         with their counsel in connection with the qualification of the Notes
         for offering and sale by the Initial Purchasers and by dealers under
         the securities or Blue Sky laws of such jurisdictions as the Initial
         Purchasers may designate and will file such consents to service of
         process or other documents necessary or appropriate in order to effect
         such qualification; 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 would subject it to general
         service of process in any jurisdiction where it is not now so subject.

                  (g) So long as any of the Notes are outstanding, the Company
         will furnish to the Initial Purchasers (i) as soon as reasonably
         practicable, a copy of each report of the Company filed with the
         Securities and Exchange Commission (the "COMMISSION") and (ii) from
         time to time such other information concerning the Company as the
         Initial Purchasers may reasonably request.

                  (h) The Company will apply the proceeds from the sale of the
         Notes to be sold by them hereunder in accordance with the description
         set forth under "Use of Proceeds" in the Offering Memorandum.

                  (i) The Company has not taken, nor will it take, directly or
         indirectly, any action designed to or that might reasonably be expected
         to cause or result in stabilization or manipulation of the price of the
         Notes to facilitate the sale or resale of the Notes. Except as
         permitted by the Act, the Company will not distribute any offering
         material in connection with the Exempt Resales. Except following the
         effectiveness of the Exchange Offer Registration Statement or the Shelf
         Registration Statement (each as defined in the Registration Rights
         Agreement), the Company will not solicit any offers to buy and will not
         offer to sell the Notes by means of any form of general solicitation or
         general advertising (within the meaning of Regulation D under the Act)
         or by means of any directed selling efforts (as defined under
         Regulation S and the Commission's releases related thereto).

                  (j) The Company will assist the Initial Purchasers in causing
         the Notes to be eligible for trading on the PORTAL market.

                  (k) From and after the Closing Date, so long as any of the
         Notes are outstanding and are "restricted Notes" within the meaning of
         Rule 144(a)(3) under the Act or, if earlier, until two years after the
         Closing Date, and during any period in which the Company is not subject

         delivered to the Initial Purchasers against payment therefor in
         accordance with the terms hereof, will have been validly issued and
         delivered, and will constitute valid and binding obligations of the
         Company entitled to the benefits of the Indenture and enforceable in
         accordance with their terms, except as enforcement thereof may be

         Company or its Subsidiaries is subject that are not adequately
         disclosed in the Offering Memorandum and that, if adversely decided,

         the Company of the Transaction Documents, the Reorganization
         Transactions, the Related Transactions or the transactions contemplated
         hereby or thereby will conflict with or constitute a breach of any of

         have a Material Adverse Effect, or (iii) any statute, law, regulation
         or judgment, injunction, order or decree applicable to the Company or
         either of its Subsidiaries or any of their respective properties,
         except any such violations that in the aggregate could not reasonably

         creation or imposition of any lien, charge or encumbrance upon any
         property or assets of any of the Company or its Subsidiaries pursuant
         to the terms of any agreement or instrument to which any of



                                       10

         them is a party or by which any of them may be bound or to which any of
         their respective properties or assets is subject, other than liens,
         charges and encumbrances disclosed in the Offering Memorandum or which
         could not reasonably be expected to have a Material Adverse Effect.

         required under the blue sky laws of any jurisdiction in connection with
         the purchase and distribution of the Securities by the Initial
         Purchasers in the manner contemplated herein and in the Offering
         Memorandum and the Registration Rights Agreement.

                  (j) Arthur Andersen LLP, who have certified certain financial
         statements of the Company and its consolidated Subsidiaries and
         delivered their reports with respect to the audited consolidated
         financial statements and schedule included in the Offering Memorandum,
         are independent public accountants with respect to the Company under
         rule 101 of the American Institute of Certified Public Accountants (the
         "AICPA") Code of Professional Conduct and the related interpretations
         and rulings.

                  (k) Sugarman & Thrope, P.C., who have certified certain
         financial statements of Fowler, Rosenau & Geary LLC ("FOWLER")
         delivered their report with respect to the audited financial statements
         included in the Offering Memorandum, are independent public accountants
         with respect to Fowler within the meaning of the Act and the applicable
         published rules and regulations thereunder.

                  (l) The consolidated historical financial statements and
         schedule of the Company and its consolidated Subsidiary included in the
         Preliminary Offering Memorandum and Offering Memorandum 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. The selected financial data set forth
         under the captions "Summary--Summary Historical Consolidated Financial
         Data" and "Selected Historical Consolidated Financial Data" in the
         Preliminary Offering Memorandum and Offering Memorandum fairly present,
         on the basis stated in the Preliminary Offering Memorandum and Offering
         Memorandum, the information included therein. The pro forma financial

         Memorandum are based on assumptions that provide a 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 Preliminary Offering



                                       11

         Memorandum and Offering Memorandum. The pro forma financial statements
         included in the Preliminary Offering Memorandum and Offering Memorandum
         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) The Company has all the requisite corporate power and
         authority to execute, deliver and perform its obligations under this
         Agreement and the Registration Rights Agreement; the execution and
         delivery of, and the performance by the Company of its obligations
         under, this Agreement and the Registration Rights Agreement have been
         duly and validly authorized by the Company and each of this Agreement
         and, as of the Closing Date, the Registration Rights Agreement will
         have been duly executed and delivered by the Company and will
         constitute a valid and legally binding agreement, enforceable against
         the Company in accordance with its terms, except as the enforcement
         hereof and thereof may be limited by bankruptcy, insolvency or other
         similar laws affecting the enforcement of creditors' rights generally
         and subject to the applicability of general principles of equity, and
         except as rights to indemnity and contribution hereunder and thereunder
         may be limited by Federal or state securities laws or principles of
         public policy.

                  (n) Except as disclosed in the Offering Memorandum, subsequent
         to the date as of which such information is given in the Offering
         Memorandum, neither the Company nor either of its Subsidiaries has
         incurred any liability or obligation, direct or contingent, or entered
         into any transaction, not in the ordinary course of business, that is
         material or will be material to the Company, taken as a whole, and
         there has not been any material change in the capital stock, or
         material increase in the short-term or long-term debt of the Company or
         either Subsidiary.

                  (o) Each of the Company and its Subsidiaries owns or leases
         all such properties as are materially necessary to the conduct of its
         operations as presently conducted, and all of the property held under
         lease by any of 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
         the applicability of general principles of equity.

                  (p) Except as permitted by the Act, the Company has not
         distributed and, prior to the later to occur of the Closing Date and
         completion of the distribution of the Notes, will not distribute any
         offering material in connection with the offering and sale of the Notes
         other than the Preliminary Offering Memorandum and Offering Memorandum
         (and any amendment or supplement thereto in accordance with Section
         4(c) hereof).

                  (q) The Company and its Subsidiaries (i) have such
         concessions, permits, licenses, consents, exemptions, franchises,
         authorizations, orders, registrations, qualifications and other
         approvals (each, an "AUTHORIZATION") of and have made all



                                       12
<PAGE>


         material 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, and (ii) 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, in each case, as are necessary to consummate the
         Reorganization Transactions and the Related Transactions and to conduct
         their respective businesses as described in the Offering Memorandum.
         Each such Authorization is valid and in full force and effect and the
         Company and each of its Subsidiaries is in material 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 limitation of the rights of the holder
         of any such Authorization; and other than as disclosed in the Offering
         Memorandum, such Authorizations do not contain net capital or other
         requirements which are materially more burdensome than those imposed on
         LaBCo. and LaBLLC immediately prior to the consummation of the
         Reorganization Transactions and the Related Transactions

                  (r) 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.

                  (s) The Company's authorized equity capitalization is as set
         forth in the Offering Memorandum under the heading "Capitalization."

                  (t) Neither the Company nor, to the knowledge of the Company,
         any employee or agent of the Company has made any payment of funds or
         received or retained any funds in violation of any law, rule or
         regulation, which violation could reasonably be expected to have a
         Material Adverse Effect.

                  (u) No holder of any security of the Company (other than
         holders of the Notes) has any right to request or demand registration
         of any security of the Company because of the consummation of the
         transactions contemplated by the Transaction Documents.

                  (v) The Company is not and, upon sale of the Notes to be
         issued and sold hereby in accordance herewith and the application of
         the net proceeds of such sale as described in the Offering Memorandum

         company" within the meaning of the Investment Company Act of 1940, as
         amended.

                  (w) When the Notes are issued and delivered pursuant to this
         Agreement, such Notes will not be of the same class (within the meaning
         of Rule 144A(d)(3) under the Act) as any security of the Company that
         is listed on a national securities exchange



                                       13

         United States automated interdealer quotation system.

                  (x) Neither the Company nor any of its affiliates (as defined
         in Rule 501(b) of Regulation D under the Act) has directly, or through
         any agent (provided that no representation is made as to the Initial
         Purchasers or any person acting on their behalf), (i) sold, offered for
         sale, solicited offers to buy or otherwise negotiated in respect of,
         any security (as defined in the Act) that is or will be integrated with
         the offering and sale of the Notes in a manner that would require the
         registration of the Notes under the Act or (ii) engaged in any form of
         general solicitation or general advertising (within the meaning of
         Regulation D under the Act) in connection with the offering of the
         Notes.

                  (y) Assuming (i) the representations and warranties of the
         Initial Purchasers in Section 2 hereof are true and correct in all
         material respects, (ii) each Initial Purchaser complies with the
         covenants set forth in Section 2 hereof, (iii) compliance by each
         Initial Purchaser with the offering and transfer procedures and

         the representations and warranties deemed to be made in the Offering
         Memorandum by purchasers to whom the Initial Purchasers initially
         resell Notes and (v) purchasers to whom the Initial Purchasers
         initially resell Notes receive a copy of the Offering Memorandum prior
         to such sale, the purchase and sale of the Notes pursuant hereto
         (including the Initial Purchasers' proposed offering of the Notes on
         the terms and in the manner set forth in the Offering Memorandum and
         Section 2 hereof) do not require registration under the Act.

                  (z) Each of the Company and its Subsidiaries and ERISA
         Affiliates has fulfilled its obligations, if any, under the minimum
         funding standards of Section 302 of the United States Employee
         Retirement Income Security Act of 1974, as amended ("ERISA") and
         Section 412 of the Internal Revenue Code of 1986, as amended (the
         "Code") and the regulations and published interpretations thereunder
         with respect to each "plan" (as defined in Section 3(3) of ERISA) for
         which the Company or any of its Subsidiaries or ERISA Affiliates have
         or may have any liability (contingent or otherwise) and each such plan
         is in compliance in all material respects with the applicable
         provisions of ERISA and such regulations and published interpretations
         thereunder. Neither the Company nor any of its Subsidiaries or ERISA
         Affiliates have incurred any 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. Neither
         the Company nor any of its Subsidiaries has engaged in any non-exempt
         "prohibited transaction" under ERISA or the Code. The term "ERISA
         AFFILIATE" means each trade or business (whether or not incorporated)
         that would be treated as a single employer with the Company under Title
         IV of ERISA or Section 412 of the Code.

                  (aa) Immediately after the consummation of the purchase and
         sale of the Notes, the fair value and present fair saleable value of
         the assets of the Company will exceed the sum of its stated liabilities
         and identified contingent liabilities; the Company is not, nor will it
         be, after giving effect to the consummation of such transactions, (i)
         left with

         unreasonably small capital with which to carry on its business as it is
         proposed to be conducted, (ii) unable to pay its debts (contingent or
         otherwise) as they mature or (iii) otherwise insolvent.

                  (bb) The statistical and market-related data included in the
         Offering Memorandum are based on or derived from sources that the
         Company believes to be reliable and accurate.

                  (cc) The statements set forth under the captions "Management's
         Discussion and Analysis of Financial Condition and Results of

         could cause our trading-related communications and data processing
         systems to fail, which could result in losses" accurately and fairly
         set forth the current state of the Company's efforts to address the
         Year 2000 Problem and the risks and costs of the Company relating to
         the Year 2000 Problem. The "YEAR 2000 PROBLEM" as used herein means any
         significant risk that computer hardware or software used in the
         receipt, transmission, processing, manipulation, storage, retrieval,
         transmission or other utilization of data or in the operation of
         mechanical or electrical systems of any kind will not, in the case of
         dates or time periods occurring after December 31, 1999, function at
         least as effectively as in the case of dates or time periods occurring
         prior to January 1, 2000.

                  (dd) Each of the stockholders' agreement, each employment
         agreement, each noncompetition agreement and each pledge agreement
         (each as described in the Offering Memorandum, together the "RELATED
         AGREEMENTS"), as of the Closing Date, will have been duly authorized,
         executed and delivered and will as of the Closing Date constitute a
         valid and legally binding agreement of the Company enforceable against
         the Company in accordance with its terms, subject, as to enforcement,
         to bankruptcy, insolvency, fraudulent transfer, reorganization,
         moratorium and similar laws of general applicability relating to or
         affecting creditors' rights and to general equity principles; and the
         Company will have obtained as of the Closing Date the signature of each
         other party to each of the Related Agreements, PROVIDED, HOWEVER, that
         the Company, makes no representation or warranty as to the
         authorization, execution or delivery of any such agreement by any other
         party thereto.

                  (ee) The Company and each of its Subsidiaries maintain a
         system of internal accounting controls sufficient to provide reasonable
         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.

         applications, trade and service marks, trade and service mark
         registrations, trade names, copyrights, licenses, inventions, trade

         (collectively, the "INTELLECTUAL PROPERTY") necessary for the conduct
         of the Company's business as now conducted or as proposed in the
         Offering Memorandum to be conducted, except to the extent a failure to
         so own, possess, license or have rights to use Intellectual Property
         could not reasonably be expected have a Material Adverse Effect.

                  (gg) LaBCo. is registered as a broker-dealer with the SEC
         under the Exchange Act and is a member organization in good standing
         with the NYSE. LaBCo. is not required to be registered with the

         supervise the activities of LaBCo., and the activities of its
         employees, to ensure that LaBCo. does not extend or maintain credit to
         or for its customers other than in accordance with the provisions of
         said Regulation T.

                  (ii) There is no franchise, contract or other document of a
         character that would be required to be described in an Offering
         Memorandum under the Act, which is not described in the Offering
         Memorandum; and the statements set forth in the Offering Memorandum
         under the headings "Description of the Capital Stock,"

         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

         Adverse Effect whether or not arising from transactions in the ordinary
         course of business, except as set forth in or contemplated in the
         Offering Memorandum.

                  (kk) 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 Offering Memorandum.

                  6. INDEMNIFICATION AND CONTRIBUTION.

                  (a) The Company agrees to indemnify and hold harmless each
Initial Purchaser and each person, if any, who controls an Initial Purchaser
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
from and against any and all losses, claims, damages, liabilities and
out-of-pocket expenses (including reasonable costs of investigation) incurred by
any such persons arising out of or based upon any untrue statement or alleged
untrue statement of a material fact contained in the Preliminary Offering
Memorandum or Offering Memorandum or in any amendment or supplement thereto, or
arising out of or based upon any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, except insofar as such losses, claims, damages, liabilities or
expenses arise out of or are based upon any untrue statement or omission or
alleged untrue statement or omission which has been made therein or omitted
therefrom in reliance upon and in conformity with the information relating to an
Initial Purchaser furnished in writing to the Company by an Initial Purchaser,
through Salomon Smith Barney Inc., expressly for use in connection therewith;
PROVIDED, HOWEVER, that the indemnification contained in this paragraph (a),
with respect to the Preliminary Offering Memorandum shall not inure to the
benefit of an Initial Purchaser on account of any such loss, claim, damage,
liability or expense arising from the sale of the Notes by such Initial
Purchaser to any person if the untrue statement or alleged untrue statement or
omission or alleged omission of a material fact contained in the Preliminary
Offering Memorandum was corrected in the Offering Memorandum and such Initial
Purchaser sold Notes to that person without sending or giving, at or prior to
the written confirmation of such sale, a copy of the Offering Memorandum (as
then amended or supplemented). The foregoing indemnity agreement shall be in
addition to any liability that the Company may otherwise have.

                  (b) If any action, suit or proceeding shall be brought against
an Initial Purchaser or any person who controls an Initial Purchaser in respect
of which indemnity may be sought against the Company in accordance with this
Section 6, such Initial Purchaser or any such person who controls such Initial
Purchaser shall promptly notify in writing the Company, and the Company shall
assume the defense thereof, including the employment of counsel reasonably
acceptable to such Initial Purchaser or such person who controls such Initial
Purchaser and payment of all fees and expenses relating to the assumption of the
defense by the Company. An


                                       17
<PAGE>


Initial Purchaser or any person who controls an Initial Purchaser shall have the
right to employ separate counsel in any such action, suit or proceeding and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such Initial Purchaser or any such person who
controls an Initial Purchaser unless (i) the Company has agreed in writing to
pay such fees and expenses, (ii) the Company has failed to assume the defense
and employ counsel on a timely basis or (iii) the named parties to any such
action, suit or proceeding (including any impleaded parties) include both such
Initial Purchaser or any such person who controls an Initial Purchaser and the
Company and such Initial Purchaser or any such person who controls an Initial
Purchaser shall have been advised by its counsel that representation of such
indemnified party and the Company by the same counsel would be inappropriate
under applicable standards of professional conduct (whether or not such
representation by the same counsel has been proposed) due to actual or potential
differing interests between them (in which case the Company shall not have the
right to assume the defense of such action, suit or proceeding (a "CONFLICTED
ACTION") on behalf of such Initial Purchaser or any such person who controls an
Initial Purchaser). It is understood, however, that the Company shall, in
connection with any such Conflicted Action, be liable for the reasonable fees
and expenses of a single counsel (in addition to any local counsel) for the
Initial Purchasers and each such person who controls an Initial Purchaser, which
firm shall be designated in writing by Salomon Smith Barney Inc., and that all
such reasonable fees and expenses shall be reimbursed as incurred as provided in
paragraph (a) hereof. The Company shall not be liable for any settlement of any
such action, suit or proceeding effected without the written consent of the
Company, but if settled with such written consent, or if there be a final
judgment for the plaintiff in any such action, suit or proceeding, the Company
agrees to indemnify and hold harmless the Initial Purchasers, to the extent
provided in paragraph (a), and any person who controls an Initial Purchaser from
and against any loss, claim, damage, liability or expense by reason of such
settlement or judgment.

                  (c) Each Initial Purchaser, severally and not jointly, agrees
to indemnify and hold harmless the Company, their respective directors and
officers and any person who controls the Company within the meaning of Section
15 of the Act or Section 20 of the Exchange Act to the same extent as the
indemnity from the Company to the Initial Purchasers set forth in paragraph (a)
hereof, but only with respect to information relating to such Initial Purchaser
furnished in writing by such Initial Purchaser through Salomon Smith Barney Inc.
expressly for use in the Preliminary Offering Memorandum or Offering Memorandum
or any amendment or supplement thereto. If any action, suit or proceeding shall
be brought against the Company, any of their respective directors or officers or
any such controlling person based on the Preliminary Offering Memorandum or
Offering Memorandum, or any amendment or supplement thereto, and in respect of
which indemnity may be sought against an Initial Purchaser pursuant to this
paragraph (c), such Initial Purchaser shall have the rights and duties given to
the Company by paragraph (b) above (except that if the Company shall have
assumed the defense thereof, such Initial Purchaser shall not be required to do
so, but may employ separate counsel therein and participate in the defense
thereof, but the fees and expenses of such counsel shall be at such Initial
Purchaser's expense), and the Company, its directors and officers and any such
controlling person shall have the rights and duties given to the Initial
Purchasers by paragraph (b) above.


                                       18
<PAGE>


The foregoing indemnity agreement shall be in addition to any liability that an
Initial Purchaser may otherwise have.

                  (d) If the indemnification provided for in this Section 6 is
unavailable to an indemnified party under paragraphs (a) or (c) hereof in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then an indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities or expenses (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and an Initial Purchaser on the other hand from the
offering of the Notes or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company on the one hand and an Initial Purchaser on the
other in connection with the statements or omissions that resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and an Initial Purchaser on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering (before deducting
expenses) received by the Company bear to the total discounts and commissions
received by such Initial Purchaser, in each case as set forth in the table on
the cover page of the Offering Memorandum. The relative fault of the Company on
the one hand and an Initial Purchaser on the other hand shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company on the one hand or by such
Initial Purchaser on the other hand and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

                  (e) The Company and the Initial Purchasers agree that it would
not be just and equitable if contribution pursuant to this Section 6 were
determined by a pro rata allocation or by any other method of allocation that
does not take account of the equitable considerations referred to in paragraph
(d) above. The amount paid or payable by an indemnified party as a result of the
losses, claims, damages, liabilities and expenses referred to in paragraph (d)
above shall be deemed to include, subject to the limitations set forth above,
any legal or other out-of-pocket expenses reasonably incurred by such
indemnified party in connection with investigating any claim or defending any
such action, suit or proceeding. Notwithstanding the provisions of this Section
6, no Initial Purchaser shall be required to contribute any amount in excess of
the amount by which the total price of the Notes purchased by it and distributed
to the public exceeds the amount of any damages that such Initial Purchaser has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. 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.

                  (f) Any losses, claims, damages, liabilities or expenses for
which an indemnified party is entitled to indemnification or contribution under
this Section 6 shall be paid by the indemnifying party to the indemnified party
as such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 6



                                       19
<PAGE>


and the representations and warranties of the Company set forth in this
Agreement shall remain operative and in full force and effect, regardless of (i)
any investigation made by or on behalf of an Initial Purchaser or any person who
controls an Initial Purchaser, the Company, its directors or officers or any
person controlling the Company, (ii) acceptance of any Notes and payment
therefor hereunder and (iii) any termination of this Agreement. A successor to
an Initial Purchaser or any person who controls an Initial Purchaser, the
Company, its directors or officers or any person controlling the Company, shall
be entitled to the benefits of the indemnity, contribution and reimbursement
agreements contained in this Section 6.

                  (g) No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action, suit or proceeding in respect of which any indemnified party
is or could have been a party and indemnity could have been sought hereunder by
such indemnified party, unless such settlement includes an unconditional release
of such indemnified party from all liability on claims that are the subject
matter of such action, suit or proceeding.

                  7. CONDITIONS OF THE INITIAL PURCHASERS' OBLIGATIONS. The
obligations of each Initial Purchaser to purchase and pay for the Notes to be
purchased by it on the Closing Date hereunder are subject to the fulfillment, in
such Initial Purchaser's sole discretion, of the following conditions:

                  (a) At the time of execution of this Agreement and on the
         Closing Date, no order or decree preventing the use of the Offering
         Memorandum or any amendment or supplement thereto, or any order
         asserting that the transactions contemplated by this Agreement are
         subject to the registration requirements of the Act shall have been
         issued and no proceedings for those purposes shall have been commenced
         or shall be pending or, to the knowledge of the Company, threatened. No
         order suspending the sale of the Notes in any jurisdiction shall have
         been issued and no proceedings for that purpose shall have been
         commenced or shall be pending or, to the knowledge of the Company,
         threatened.

                  (b) At the Closing Date, the Reorganization Transactions and
         the Related Transactions shall have been consummated; and the Company

         Transactions.

                  (c) Subsequent to the date hereof, (i) except as disclosed or
         contemplated in the Offering Memorandum, there shall not have occurred
         any material adverse change in the condition (financial or other),
         business, prospects, properties, assets, net worth or results of
         operations of the Company, taken as a whole, which, in the opinion of
         the Initial Purchasers, would materially adversely affect the market
         for the Notes, or (ii) the Offering Memorandum shall not contain any
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary in order to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading, if amending or supplementing the Offering
         Memorandum to correct any such



                                       20
<PAGE>


         misstatement or omission could, in the sole judgment of the Initial
         Purchasers, materially adversely affect the marketability of the Notes.

                  (d) The Initial Purchasers shall have received on the Closing
         Date an opinion of Fulbright & Jaworski LLP, counsel for the Company,

         request.

                  (f) The Initial Purchasers shall have received a "cold
         comfort" letter addressed to the Initial Purchasers, and dated the date
         hereof and the Closing Date, from each of Arthur Andersen LLP and
         Sugarman & Thrope, P.C., substantially to the effect set forth in
         EXHIBIT B hereto.

                  (g) (i) There shall not have been any material change in the
         capital stock of the Company or any Subsidiary nor any material
         increase in the short-term or long-term debt of the Company or any
         Subsidiary from that set forth or contemplated in the Offering
         Memorandum; (ii) except as disclosed or contemplated by the Offering
         Memorandum, the Company and the Subsidiaries shall not have any
         liabilities or obligations, direct or contingent (whether or not in the
         ordinary course of business), that are material to the Company and the
         Subsidiaries, taken as a whole; (iii) all the representations and
         warranties of the Company contained in this Agreement shall be true and

         Purchasers), to the effect set forth in this Section 7(g) and in
         Section 7(h) hereof.

                  (h) The Company shall not have failed at or prior to the
         Closing Date to have performed or complied with any of their respective
         agreements herein contained and required to be performed or complied
         with by them hereunder at or prior to the Closing Date.

                  (i) There shall not have been any announcement by any
         "nationally recognized statistical rating organization," as defined for
         purposes of Rule 436(g) under the Act, that (i) it is downgrading its
         rating assigned to any class of Notes of the Company (including the
         Notes), or (ii) it is reviewing its ratings assigned to any class of
         Notes of the Company (including the Notes) with a view to possible
         downgrading, with negative implications or direction not determined.

                  (j) The Notes shall have been approved for trading on PORTAL.

                  (k) The Company shall have furnished or caused to be furnished
         to the Initial Purchasers such further certificates and customary
         closing documents as the Initial Purchasers shall have reasonably
         requested.

                  All such opinions, certificates, letters and other documents
will be in compliance with the provisions hereof only if they are reasonably
satisfactory in form and substance to the Initial Purchasers.

                  Any certificate or document signed by any officer of the
Company and delivered to the Initial Purchasers, or to counsel for the Initial
Purchasers, shall be deemed a representation and warranty by the Company to the
Initial Purchasers as to the statements made therein.

                  8. EXPENSES.

hereunder is consummated or this Agreement is terminated pursuant to Section 9
hereof, the Company agrees to pay the following costs and expenses and all other
costs and expenses incident to the performance by them of their obligations
hereunder: (i) the printing or reproduction of the Preliminary Offering
Memorandum and Offering Memorandum (including financial statements thereto), and
each amendment or supplement to any of them, this Agreement, the Registration
Rights Agreement and the Indenture; (ii) the delivery (including postage, air
freight charges and charges for counting and packaging) of such copies of the
Offering Memorandum, the Preliminary Offering Memorandum and all amendments or
supplements thereto as may be reasonably requested for use in connection with
the offering and sale of the Notes; (iii) the printing, authentication, issuance
and delivery of certificates for the Notes, including any stamp taxes in
connection with the original issuance and sale of the Notes; (iv) the printing
(or reproduction) and delivery of the preliminary and supplemental Blue Sky
Memoranda and all other agreements and documents printed (or reproduced) and
delivered in connection with the offering of the Notes; (v) the application for

in Section 4(f) hereof (including the reasonable fees, expenses and
disbursements of counsel for the Initial Purchasers relating to the preparation,
printing or reproduction, and delivery of the preliminary and supplemental Blue
Sky Memoranda and such qualification); and (vii) the fees and expenses of the
Company's accountants and the fees and expenses of counsel (including local and
special counsel) for the Company.

                  (b) If the purchase and sale of the Notes hereunder is not
consummated because any condition to the obligations of the Initial Purchaser
set forth in Section 7 hereof is not satisfied, because this Agreement is
terminated because of any failure, refusal or inability on the part of the
Company to perform all obligations and satisfy all conditions on their part to
be performed or satisfied hereunder other than by reason of a default by an
Initial Purchaser in payment for the Notes on the Closing Date, the Company
shall reimburse the Initial Purchasers promptly upon demand for all reasonable
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 Notes and the other transactions contemplated hereby; PROVIDED
that the


                                       22
<PAGE>



defaulting Initial Purchaser shall reimburse the Company upon demand for all
reasonable out-of-pocket expenses (including reasonable fees and expenses for
law and accounting services and printing costs) that shall have been incurred by
it in connection with the proposed purchase and sale of the Notes and the
transactions contemplated hereby.

                  9. TERMINATION OF AGREEMENT. (a) This Agreement shall be
subject to termination in the absolute discretion of the Initial Purchasers,
without liability on the part of the Initial Purchasers to the Company, by
notice to the Company, if prior to the Closing Date, (i) trading in securities
generally on the New York Stock Exchange, American Stock Exchange or the Nasdaq
National Market shall have been suspended or materially limited, (ii) a general
moratorium on commercial banking activities in New York shall have been declared
by either Federal or New York state authorities or (iii) there shall have
occurred any outbreak or escalation of hostilities or other international or
domestic calamity, crisis or change in political, financial or economic
conditions, the effect of which on the financial markets of the United States or
the market for the Notes is such as to make it, in the sole judgment of the
Initial Purchasers, impracticable or inadvisable to commence or continue the
offering of the Notes on the terms set forth on the cover page of the Offering
Memorandum (or if not yet in existence then the Preliminary Offering Memorandum)
or to enforce contracts for the resale of the Notes by the Initial Purchasers.
Notice of such termination may be given to the Company by telegram, telecopy or
telephone and shall be subsequently confirmed by letter.

                  (b) If any Initial Purchaser shall fail to purchase and pay
for any of the Notes agreed to be purchased by such Initial Purchaser hereunder
and such failure to purchase shall constitute a default in the performance of
its obligations under this Agreement, the remaining Initial Purchaser shall be
obligated to take up and pay for the Notes which the defaulting Initial
Purchaser agreed but failed to purchase; PROVIDED, HOWEVER, that in the event
that the aggregate principal amount of Notes which the defaulting Initial
Purchaser agreed but failed to purchase shall exceed 10% of the aggregate
principal amount of Notes set forth in Schedule I hereto, the remaining Initial
Purchaser shall have the right to purchase all, but shall not be under any
obligation to purchase any, of the Notes, and if such non-defaulting Initial
Purchaser does not purchase all the Notes, this Agreement will terminate without
liability to the non-defaulting Initial Purchaser or the Company. In the event
of a default by any Initial Purchaser as set forth in this Section 9(b), the
Closing Date shall be postponed for such period, not exceeding seven days, as
the non-defaulting Initial Purchaser shall determine in order that the required
changes in the Offering Memorandum or in any other documents or arrangements may
be effected. Nothing contained in this Agreement shall relieve any defaulting
Initial Purchaser of its liability, if any, to the Company or the non-defaulting
Initial Purchaser for damages occasioned by its default hereunder.

                  10. INFORMATION FURNISHED BY THE INITIAL PURCHASERS. The
statements set forth in the last paragraph on the cover page and in the third
and ninth paragraphs under the caption "Plan of Distribution" in the Preliminary
Offering Memorandum and Offering Memorandum, constitute the only information
furnished by the Initial Purchasers as such information is referred to in
Sections 5(b) and 6 hereof.

                   Form of Opinion of Fulbright & Jaworski LLP


                  1. The Company has the requisite corporate power and authority
to execute, deliver and perform its obligations under the Indenture; the
execution and delivery of, and the performance by the Company of its obligations
under the Indenture have been duly and validly authorized by the Company; and
the Indenture has been duly executed and delivered by the Company and, assuming
due authorization, execution and delivery by the Trustee, constitutes the valid
and legally binding agreement of the Company, enforceable against the Company in
accordance with its terms, except as enforcement thereof may be limited by
bankruptcy, insolvency or other similar laws affecting the enforcement of
creditors' rights generally and subject to the applicability of general
principles of equity.

                  2. No qualification of the Indenture under the 1939 Act is
required in connection with the offer and sale of the Notes as contemplated by
the Purchase Agreement.

                  3. The Notes have been duly authorized by the Company and,
when authenticated by the Trustee in accordance with the Indenture and delivered
to the Initial Purchasers against payment therefor in accordance with the terms
of the Purchase Agreement, will have been validly issued and delivered, and will
constitute valid and binding obligations of the Company entitled to the benefits
of the Indenture and enforceable in accordance with their terms, except as
enforcement thereof may be limited by bankruptcy, insolvency or other similar
laws affecting the enforcement of creditors' rights generally and subject to the
applicability of general principles of equity.

                  4. All the outstanding shares of capital stock of the Company
have been duly authorized and validly issued, are fully paid and nonassessable.

                  5. 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, lease and operate its properties and to conduct its business as described
in the Offering Memorandum, and is duly registered and qualified to do business
as a foreign corporation and is in good standing under the laws of each
jurisdiction which requires such registration or qualification, except where the
failure to so register or qualify could not reasonably be expected to have a
Material Adverse Effect.

                  6. 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 its jurisdiction of
organization; and the partnership interests in LaBCo. and the membership
interests in LaBLLC have been duly and validly authorized and issued and are
fully paid and nonassessable and are owned of record directly or indirectly by
the Company, to the knowledge of such counsel, to the knowledge of such counsel,
free and clear of all liens, encumbrances, equities or claims.

                  7. The Company's authorized equity capitalization is as set
forth in the Offering Memorandum under the heading "Capitalization."

                  8. (x) The issuance, offer, sale or delivery of the Notes, (y)
the execution, delivery or performance of the Transaction Documents by the
Company, or (z) the consummation by the Company or any Subsidiary of any of the
transactions contemplated by the Transaction Documents, the Reorganization
Transactions or the Related Transactions, will not conflict with or constitute a
breach of any of the terms or provisions of, or a default under, (i) the
organizational documents of the Company or any Subsidiary, (ii) any agreement,
indenture, lease or other document described in the Offering Memorandum under
the headings "Certain Transactions--Reorganization and Related Transactions--
Reorganization" and "--Interest on Indebtedness" or filed as an Exhibit to the
Company's Registration Statement on Form S-1 (No. 333-80791) relating to the
initial public offering of its Common Stock (collectively, to be hereinafter
referred to as the "MATERIAL CONTRACTS"), or (iii) any statute, law, ordinance
or administrative, governmental or self-regulatory organization rule or
regulation known to us to be applicable to the Company or any Subsidiary or any
of their respective properties, or any filing or judgment, injunction, order or
decree known to us of any court or governmental agency or body having
jurisdiction over the Company or any Subsidiary, except any which individually
or in the aggregate could not reasonably be expected to have a Material Adverse
Effect; and the consummation of the transactions contemplated by the Transaction
Documents, the Reorganization Transactions and the Related Transactions will not
result in the creation or imposition of any lien, charge or encumbrance upon any
property or assets of the Company or any Subsidiary pursuant to the terms of any
Material Contract, other than as disclosed in the Offering Memorandum; PROVIDED,
HOWEVER, that, for the purposes of this paragraph 8 insofar as the consummation
of the Reorganization Transactions and Related Transactions are concerned, such
counsel need not express any opinion with respect to Federal or state securities
laws, other antifraud laws, and fraudulent transfer laws, or as to bankruptcy,
insolvency, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights.

                  9. No consent, approval, authorization, filing with or order
of any court or governmental agency or body is required in connection with the
transactions contemplated in the Purchase Agreement or in the Indenture or the
Registration Rights Agreement, except such as will be obtained under the Act and
the Trust Indenture 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 Initial Purchasers in the manner contemplated herein and in
the Offering Memorandum and the Registration Rights Agreement.

                  10. The Company has the requisite corporate power and
authority to execute, deliver and perform its obligations under the Purchase
Agreement and the Registration Rights Agreement; the execution and delivery of,
and the performance by the Company of its obligations under, the Purchase
Agreement and the Registration Rights Agreement have been duly and validly
authorized by the Company, and each of the Purchase Agreement and the
Registration Rights Agreement has been duly executed and delivered by the
Company. The Registration Rights Agreement constitutes the valid and legally
binding agreement of the Company, enforceable against the Company in accordance
with its terms, except as the enforcement thereof may be limited by bankruptcy,
insolvency or other similar laws affecting the enforcement of creditors' rights
generally and subject to the applicability of general principles of





                                      A-2

<PAGE>

equity, and except as rights to indemnity and contribution thereunder may be
limited by Federal or state securities laws or principles of public policy.

                  11. Each of the Related Agreements has been duly authorized,
executed and delivered by the Company and constitutes a valid and binding
obligation of the Company enforceable in accordance with its terms, subject, as
to enforcement, to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting
creditors' rights and to general equity principles.

                  12. 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.

                  13. The Company and its Subsidiaries (i) have such
Authorizations of, and have made all filings with and notices to, the courts and
the governmental agencies or bodies of the United States of America and the
State of New York and all applicable self-regulatory organizations and (ii) 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, in each case, 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; and other than as disclosed
in the Offering Memorandum, such Authorizations contain no net capital or other
requirements or conditions that are materially more burdensome than those
imposed on LaBCo. or LaBLLC immediately prior to the consummation of the
Reorganization Transactions.

                  14. Assuming (i) the representations and warranties of the
Company in Section 5 of the Purchase Agreement are true and correct, (ii) the
representations and warranties of the Initial Purchasers in Section 2 of the
Purchase Agreement are true and correct, (iii) the Company complies with the
covenants set forth in Section 4 of the Purchase Agreement, (iv) the Initial
Purchasers comply with the covenants set forth in Section 2 of the Purchase
Agreement, (v) the Initial Purchasers comply with the offering and transfer
procedures and restrictions described in the Offering Memorandum, (vi) the
representations and warranties deemed to be made in the Offering Memorandum by
purchasers to whom the Initial Purchasers initially resell Notes are true and
correct and (vii) purchasers to whom the Initial Purchasers initially resell
Notes receive a copy of the Offering Memorandum prior to such sale, the purchase
and sale of the Notes pursuant to the Purchase Agreement (including the Initial
Purchasers' offering and sale of the Notes on the terms and in the manner set
forth in the Offering Memorandum and Section 2 of the Purchase Agreement) do not
require registration under the Act.

                  15. The Indenture, the Notes and the Registration Rights
Agreement conform in all material respects to the descriptions thereof contained
in the Offering Memorandum.

                  16. To our knowledge, there is no pending or threatened
action, suit or proceeding by or before any court or governmental agency,
authority or body or any arbitrator involving the Company or any of its
Subsidiaries or its or their property of a character which would be required to
be disclosed in a prospectus pursuant to the Act which is not adequately



                                      A-3

<PAGE>


disclosed in the Offering Memorandum, and there is no franchise, contract or
other document of a character which would be required to be described in a
prospectus pursuant to the Act which is not described in the Offering
Memorandum. The statements included in the Offering Memorandum under the
headings "Description of Capital Stock," "Business--Regulatory Matters" and
"--Operations--NYSE Rules Governing Our Specialist Activities," "Certain
Transactions," "Employment Agreements and Noncompetition Agreements," Incentive
Awards to Our Employees," "Description of Notes," "Description of Certain Other
Indebtedness" and "Certain United States Federal Income Tax Consequences to
Non-U.S. Persons" fairly summarize the matters therein described.

                  17. The Company is not, nor immediately after the sale of the
Notes to be sold under the Purchase Agreement and the application of the
proceeds from such sale (as described in the Offering Memorandum under the
caption "Use of Proceeds") will it be an "investment company" as such term is
defined in the Investment Company Act of 1940, as amended.

                  18. The Material Contracts do not contain any provisions that
prohibit any Subsidiary of the Company, 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 Offering Memorandum.

                  19. 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 and the Related Transactions, to
register any such securities under the Act, or to qualify any indenture under
the 1939 Act.

                  20. LaBCo. is registered as a broker-dealer with the SEC under
the Exchange Act and is a member organization in good standing with the NYSE.
LaBCo. is not required to be registered with the securities authority of any
state.

                  21. Neither the consummation of the transactions contemplated
by the Purchase Agreement nor the sale, issuance, execution or delivery of the
Notes will violate Regulation T, U or X of the Board of Governors of the Federal
Reserve system.

                  We have participated in conferences with officers and other
representatives of the Company, representatives of the independent public
accountants for the Company, representatives of the Initial Purchasers and
counsel for the Initial Purchasers at which conferences the contents of the
Offering Memorandum and related matters were discussed, and, although we have
not independently verified and are not passing upon and assume no responsibility
for the accuracy, completeness or fairness of the statements contained in the
Offering Memorandum (except to the extent specified in paragraph 16), and that
our judgment as to materiality is, to the extent we deem proper, based in part
upon the views of appropriate officers and other representatives of the Company,
nothing has come to our attention that leads us to believe that the Offering
Memorandum, as of its date or as of the date hereof, contained or contains an
untrue statement of a material fact or omitted or omits to state a material fact
required to be stated therein or necessary to make the statements contained
therein, in the light of



                                      A-4

<PAGE>


the circumstances under which they were made, not misleading (it being
understood that we express no opinion with respect to the financial statements
and related notes thereto and the other financial, statistical and accounting
data included in the Offering Memorandum).

                  LaB Investing Co. L.L.C.                     84.0592%

                  LIMITED PARTNER:

                  SECTION 8.03.     Notwithstanding anything to the contrary

adjustment, allocation or distribution

                                       -4-


<PAGE>


described in Treas. Reg. section 1.704-1(b)(2)(ii)(d)(4), (5) or (6) which
creates or increases a deficit balance in its capital account, it shall be
allocated all income (gross income if required by Treasury Regulations and net
profits if not so required) of the Partnership in proportion to its negative
capital account balance in an amount and manner sufficient to eliminate such
deficit balance as quickly as possible. Such allocation of net profits or income
is herein termed a "QUALIFIED INCOME OFFSET" within the meaning of Treas. Reg.
section 1.704-1(b)(2)(ii)(d), and shall comply with such provision in all
respects. In any such case, the General Partner shall be allocated in each
subsequent period all net profits otherwise allocable to the Limited Partner
until the aggregate amount of the net profits so allocated to the General
Partner shall equal the amount of net profits which would otherwise have been
allocated to the General Partner absent the allocation of net profits or gross
income to the Limited Partner pursuant to the Qualified Income Offset, after
which allocations of net profits and net losses of the Partnership shall be made
in accordance with Section 8.02 hereof.

                  SECTION 8.04. For Federal income tax purposes, net profits and
net losses, and any item of income, gain, loss, deduction or credit, including,
without limitation, net long-term capital gain, net long-term capital loss, net
short-term capital gain, net short-term capital loss, ordinary income and
ordinary loss shall be allocated so as to take account of the variation between
the adjusted tax basis and the book value of any property contributed by the
Partners to the Partnership in accordance with the principles of Section 704(c)
of the Internal Revenue Code of 1986, as amended (the "CODE"), as prescribed by
Treas. Reg. section 1.704-1(b)(4)(i), and subject to the limitations of Treas.
Reg. section 1.704-1(c)(2). All such allocations shall, in addition, take
account of each Partner's varying interest for any particular fiscal year and
withdrawals made under this Agreement in accordance with Section 706 of the
Code.

                  SECTION 8.05. The provisions of this Agreement are intended to
comply with Treas. Reg. section 1.704-1(b) issued pursuant to Section 704(b) of
the Code and shall be interpreted in a manner consistent with such Treasury
Regulations. The General Partner may, without the consent of the Limited
Partner, amend the provisions of this Agreement and the manner in which net
profits and net losses (or other items) are allocated to the extent (but only to
the extent) necessary to comply with Treas. Reg. section 1.704-1(b). In
addition, the capital accounts of the Partners shall at all times be adjusted
and maintained in accordance with the requirements of Treas. Reg. section
1.704-1(b)(2)(iv), and the provisions of this Agreement shall be construed in
a manner consistent therewith, and shall be adjusted as required by Treas. Reg.
section 1.704- 1(b)(2)(iv)(G).

                                   ARTICLE IX

                        ADMISSION OF ADDITIONAL PARTNERS

                  SECTION 9.01. Subject to compliance with the foregoing terms
of this Agreement, additional limited partners may be admitted to the
Partnership upon such terms and conditions as the General Partner shall
determine, such admission shall occur immediately upon the consent of the
General Partner, and no other consent of the Limited Partner shall be required
for the admission of additional limited partners. Upon the admission of a new
limited partner to the Partnership, the existing Partners' respective percentage
interests in the profits and losses of the

                                       -5-

<PAGE>


Partnership, as determined pursuant to Article VIII hereof, shall be adjusted
proportionately to reflect the admission of such new limited partner and the
dilution of the respective percentage interests of all the other existing
Partners. The admission of a new limited partner shall not dissolve the
Partnership, and the continuing Partnership shall be the same firm for all
purposes.

                  SECTION 9.02. The consent of the Limited Partner will be
required for the admission of a new or additional general partner, other than in
accordance with Article XVI hereof.

                                    ARTICLE X

                                   WITHDRAWAL

Partner, the Limited Partner may withdraw from the Partnership effective as of
the end of any calendar quarter, or effective as of such other date as the
General Partner and the Limited Partner may mutually agree, provided, however,
that any withdrawal of capital hereunder shall be subject to the limitations set
forth in Section 14.01 hereof.

                  SECTION 10.02. At any time, the General Partner may, by
written notice (a "WITHDRAWAL NOTICE") given to the Limited Partner, require the
Limited Partner to withdraw from the Partnership effective upon the close of
business on the date specified in the Withdrawal Notice.

                  SECTION 10.03. The term "INVENTORY DATE" shall mean the
effective date of the Limited Partner's withdrawal.

Partnership without the consent of the Limited Partner.

                                  FINAL PAYMENT

                  SECTION 11.01. In the event the Limited Partner withdraws from
the Partnership, a payment (the "FINAL PAYMENT") shall be made to the Limited
Partner in an amount representing the value of its interest in the Partnership.
The Final Payment shall be determined as of the Inventory Date applicable to the
Limited Partner and, subject to the provisions of Article XIV hereof, shall be
made ninety (90) days after the Inventory Date or on such earlier date as the
General Partner shall determine. The Final Payment shall be made without
interest, except that payment of the capital account of the Limited Partner
shall be made with interest from the Inventory Date at the broker's call rate,
as in effect from time to time. The Final Payment shall be made in cash, unless
the General Partner determines to make payment, in whole or in part, in kind.

                 SECTION 11.02. The amount of the Final Payment shall be
determined by the General Partner in accordance with generally accepted
accounting principles consistently applied

                                       -6-

and with such reserves for any obligations, claims, causes of action,
liabilities or other contingencies as the General Partner may deem necessary or
proper, subject to the following provisions: (i) each position in listed
securities, whether long or short, shall be marked to market on the Inventory
Date at the closing price on the principal exchange on which such securities are
traded, but, if there were no sales in such securities on the Inventory Date,
then such securities shall be marked to either the mean between the bid and
asked prices thereof on such date or, in the sole discretion of the General
Partner, the last closing price of such securities on the principal exchange on
which such securities are traded; (ii) each position in over-the-counter
securities, whether long or short, shall be marked to the market on the
Inventory Date at the last sales price thereof as reported by the National
Association of Securities Dealers Automated Quotation System or, if not so
reported, to the mean between the high bid and low asked prices in the
quotations furnished by the National Association of Securities Dealers, Inc.,
where available, or in the quotations furnished by one or more of the principal
dealers in such securities; (iii) each position in securities which are not
readily marketable shall be valued as of the Inventory Date by the General
Partner in its sole, absolute and final discretion; (iv) although the
Partnership's fiscal year may not have closed for other purposes, the
Partnership's fiscal year shall be deemed to have closed on the Inventory Date
for the limited purpose of determining the value of the interest of the Limited
Partner; (v) allocation of unrealized gains or losses in securities held by the
Partnership shall be made on the basis that such securities were sold on the
Inventory Date at the market value thereof; (vi) no value will be placed upon or
will any allowance be made for or on account of the goodwill or trade name of
the Partnership; and (vii) all furniture, fixtures, leasehold improvements,
prepaid expenses and similar items capitalized on the books of the Partnership
and any memberships purchased by the Partnership will be valued at the book
value thereof, except that depreciation, amortization or other allowances for
exhaustion of such items between the first day of the fiscal year in which the
Inventory Date occurs and the Inventory Date shall be taken into account at the
rates then employed by the Partnership for such items, whether or not the books
of the Partnership actually reflect such depreciation, amortization or other
allowance on the Inventory Date. No value will be placed upon nor will allowance
be made for or on account of printing and stationery and other consumable assets
charged as an expense by the Partnership upon acquisition.

                  SECTION 11.03. In determining the value of the interest in the
Partnership of the Limited Partner, the General Partner may establish such
reserves as it deems prudent to provide for items of expense and loss relating
to the portion of the fiscal year of the Partnership prior to the Inventory
Date, and for all liabilities, contingent or otherwise, attributable to such
period or to any or all prior periods during which the Limited Partner was a
Partner or the interest of the Limited Partner continued at the risk of the
business of the Partnership.

                  SECTION 11.04. A statement of the amount due from the
Partnership in respect of the Final Payment of the Limited Partner shall be
promptly prepared. A copy of the statement shall be furnished to the Limited
Partner. In the event any amount shall be due from the Limited Partner to the
Partnership, the same shall be remitted to the Partnership promptly.

                  SECTION 11.05. Reserve accounts shall be applied or liquidated
with all due expedition, as determined by the General Partner in conjunction
with the Partnership's accountants.

                                       -7-

<PAGE>


To the extent that any reserve account shall exceed, or shall be estimated by
the General Partner to exceed, the amount of the obligations, claims, causes of
action or other contingencies for which it was established, the Limited Partner
shall be paid its share of any such excess without interest. To the extent, if
at all, that the reserve account proves insufficient or no reserve account was
established therefor, the Limited Partner shall promptly remit to the
Partnership its share of such shortfall, without interest.

                  SECTION 11.06. Any dispute arising out of, or connected with,
determinations reflected in any statement furnished pursuant to this Article XI
shall, unless resolved by the parties, be submitted to the Partnership's
accountants, and any determination by such accountants shall be final, binding
and conclusive on the Partnership and the Limited Partner.

                  SECTION 11.07. In no event shall the Limited Partner be
required to remit to the Partnership any amount in excess of the Final Payment,
or to remit any amount to the Partnership after the expiration of the statute of
limitations applicable to any claim or potential claim with respect to an
action, omission to act, event or occurrence which took place prior to the
Limited Partner's withdrawal from the Partnership.

                                  ARTICLE XII

                ALLOCATION OF FORMER PARTNERS' PROFITS AND LOSSES

                  SECTION 12.01. At such time as the Limited Partner shall no
longer be entitled to participate in the profits and losses of the Partnership,
its interest in future profits and losses of the Partnership shall be allocated
in such manner and in such proportions as shall be determined by the General
Partner, provided, however, that no allocation shall be made to the Limited
Partner without its consent.

                                  ARTICLE XIII

be open to inspection by the Limited Partner, or by its accredited
representatives, at any reasonable time during normal business hours.

                                   ARTICLE XIV

                             POSTPONEMENT OF PAYMENT

                  SECTION 14.01.  Notwithstanding any other provision of this
Agreement, in accordance with Rule 313.11 of the Exchange, all withdrawals of
capital hereunder shall be made only with the prior written approval of the
Exchange and upon six months written notice to the

                                       -8-

<PAGE>


Partnership given no sooner than six months after such contribution was first
made, unless a different period of notice is consented to by the General Partner
and approved by the Exchange. In addition, any payment to be made by the
Partnership pursuant to Article XI hereof or otherwise hereunder to, or
withdrawal of capital by, any Partner shall be postponed if, but only to the
extent that, after giving effect to the payment or withdrawal, such payment or
withdrawal, or any part thereof, would be prohibited by the provisions of
Securities and Exchange Commission Rule 15c3-1 (or any successor Rule), or any
Rule of the Exchange, or would render the Partnership unable to meet its capital
requirements as a specialist firm on the Exchange. Any such postponement shall
be until such time as the payment or withdrawal could be made pursuant to the
provisions of said Rule 15c3-1 (or any successor Rule) and any Rule of the
Exchange and until the Partnership, after giving effect to the payment or
withdrawal, would be in compliance with its capital requirements as a specialist
firm on the Exchange. In addition, any payment to be made by the Partnership
pursuant to Article XI hereof or otherwise hereunder to, or withdrawal of
capital by, any Partner shall be postponed if, but only to the extent that,
after giving effect to the payment or withdrawal, such payment or withdrawal, or
any part thereof, would contravene, result in any breach of, or constitute a
default under, or result in the creation of any lien in respect of the property
of the Partnership under, any indenture, mortgage, deed of trust, loan, purchase
or credit agreement, lease, organizational document, or any other agreement or
instrument to which the Partnership is bound or by which the Partnership or any
of its properties may be bound or affected.

                  SECTION 14.02. In determining for purposes of Section 14.01
hereof whether any payment or withdrawal can be made and the extent thereof, any
amounts due from the Partnership to or in respect of any Partner which other
amounts are payable at or prior to the date on which such payment or withdrawal
was initially scheduled (disregarding any postponement of the Partnership's
obligation to make such payment), shall be deemed to have been paid and the net
capital of the Partnership appropriately reduced.

                  SECTION 14.03. Interest at the broker's call rate, as in
effect from time to time, shall be payable in respect of payments postponed
pursuant to the provisions of this Article XIV.

                                   ARTICLE XV

                          COMPLIANCE WITH THE EXCHANGE

                  SECTION 15.01. This Agreement and all matters and things to be
done and performed in connection with the Partnership business shall be subject
to the Constitution, Rules, requirements and regulations, so far as applicable
thereto, of the Exchange and shall be conducted strictly in compliance

be in conflict with any provision of the Constitution, Rules, requirements or
regulations of the Exchange, the same shall be deemed modified so as to conform
therewith.

Agreement, if at any time it shall be determined that the General Partner is
insolvent (as such term is used in Title 11 of the United States Code), the
Partnership shall be dissolved, unless the Limited Partner appoints another
subsidiary of the Limited Partner to serve as the general partner of the
Partnership and such subsidiary is admitted as the general partner of the
Partnership.

                  SECTION 16.02. No person, other than the General Partner, the
Limited Partner or a subsidiary or affiliate of either of them shall have any

Partnership, (ii) to execute powers of substitution, (iii) to guarantee the
signatures of others to assignments of securities, and (iv) to make any
certification or guarantee of any signature on documents submitted in support of

percentages specified in Rules 326(a) and 326(b) of the Rules of the Board of
Directors of the Exchange during the six months immediately preceding the date
of the dissolution, may be postponed for a period of up to (6) six months of the

compliance with said rules, and any such capital so retained by the Partnership
after the date of dissolution shall continue to be subject to all debts and

                  SECTION 4.01. MANAGEMENT. The management of the Company shall
be vested in a Managing Committee (the "MANAGING COMMITTEE") which shall be
responsible for the determination of all questions of business, policy and
operation of the Company. The duties of the Managing Committee shall include,
but not be limited to, the management of the Firm on behalf of the Company, as
provided in Article VI of the Amended and Restated Articles of Partnership of
the Firm, dated as of the date hereof, and as subsequently amended (the "FIRM
AGREEMENT"), and the



                                       3

Exchange, and who are otherwise acceptable to the Exchange, to act on behalf of
the Firm in connection with the Firm's day-to-day dealings with the Exchange.
Without limiting the foregoing, the Managing Committee shall have full power and
authority on behalf of the Member, at any time and from time to time, in
accordance with the rules of any national securities exchange, to determine in
good faith the value of Company and Firm assets in those cases where such assets
do not have readily ascertainable market values, and to review and determine
salaries of employees of the Company and the Firm. Decisions of the Managing
Committee shall be presumed to be within its scope of authority and shall be
binding upon the Company and the Member. The Managing Committee shall be
composed of George M.L. LaBranche, IV, Alfred O. Hayward, Jr. and James G.
Gallagher. The Member may remove one or more members of the Managing Committee
at such time or times as it shall determine in its sole discretion or increase

by the terms of this Agreement, any matter is subject to action or determination
by the Managing Committee, such action or determination shall by approved or
made by a majority of the persons constituting the Managing Committee.

                  SECTION 4.02. LIABILITY AND INDEMNIFICATION.

                           (a) Except as otherwise provided by law, no member of
the Managing Committee shall be liable, responsible or accountable in any way
for damages or otherwise to the Company or to the Member for any act or failure
to act pursuant to this Agreement unless there is a judicial determination that
(i) such person acted in bad faith, (ii) the conduct of such person constituted
intentional misconduct or a knowing violation of law, (iii) such person gained a
financial benefit to which he or she was not legally entitled or (iv) such
person failed to perform his or her duties, specifically with respect to
distributions under Section 508(a) of the New York Limited Liability Company
Law, in good faith and with that degree of care that an ordinarily prudent
person in a like position would use under similar circumstances.

                           (b) The Company shall indemnify, defend and hold
harmless each member of the Managing Committee (severally, an "INDEMNITEE" and
collectively, the "INDEMNITEES"), from and against any claims, losses,
liabilities, damages, fines, penalties, costs and expenses (including, without
limitation, reasonable fees and disbursements of counsel and other
professionals) arising out of or in connection with any act or failure to act by
an Indemnitee pursuant to this Agreement, or the business and affairs of the
Company, to the fullest extent permitted by law; provided, however, that an
Indemnitee shall not be entitled to indemnification hereunder if there is a
judicial determination that (i) such Indemnitee's actions or omissions to act
were made in bad faith or were the result of active and deliberate dishonesty
and were material to the cause of action so adjudicated, or (ii) such Indemnitee
personally gained a financial benefit to which the Indemnitee was not legally
entitled.

                  SECTION 4.03. ACTIONS OF MEMBER REQUIRING MANAGING COMMITTEE

deliver any assignment for the benefit of creditors or any bond, confession of
judgment, or indemnity bond (except pursuant to Section 8.04) (iii) make,
execute or deliver in the name of the Company or the Firm any chattel mortgage,
security agreement or financing statement; (iv) become a surety, guarantor or
accommodation party to any obligations in



                                       4
<PAGE>

the name or in the credit of the Company or the Firm; (v) lend any money of the
Company or the Firm or extend any credit of the Company or the Firm except in
the regular course of business; and (vi) without being limited by the foregoing,
do any act or enter into transactions on behalf of the Company or the Firm
except in the regular course of business and consistent with the terms of this
Agreement.

                  SECTION 6.01. ADMISSION OF NEW MEMBERS. New members may be
admitted to the Company upon such terms and conditions as the Managing Committee
shall determine. The admission of a new member or members shall not dissolve the
Company, and the Company shall be the same firm for all purposes.

                                   ARTICLE VII

Member specifying the date upon which the Company shall dissolve.

                  SECTION 7.02. BANKRUPTCY. Any bankruptcy of the Member shall

<PAGE>

                  SECTION 7.03. EVENT OF DISSOLUTION OF THE FIRM.
Notwithstanding anything to the contrary contained herein, in the event of the
dissolution of the Firm upon the expiration of the term of the Firm Agreement,
or any extension or renewal thereof, the Member agrees that any withdrawal of

indebtedness" to exceed the percentages specified in Rules 326(a) and 326(b) of
the Rules of the Board of Directors of the Exchange during the six months
immediately preceding the date of the dissolution, may be postponed for a period
of up to (6) six months of the stated date of dissolution, as the Managing
Committee may deem necessary to ensure compliance with said rules, and any such
capital so retained by the Firm after the date of dissolution shall continue to
be subject to all debts and obligations of the Firm.

                                  ARTICLE VIII

                                  MISCELLANEOUS

Comptroller of the Currency
Administrator of National Banks

Central District Office

February 11, 1999

Mr. Richard J. Hidy
Vise president and
Deputy General Counsel
StarBanc Corporation
425 Walnut Street
P.O. Box 1038, ML 9140
Cincinnati, OH 45201-1038

Dear Mr. Hidy:

The Office of the Comptroller of the Currency has received your letter
concerning the title change and the appropriate amendment to the bank's articles
of association. The Office has recorded that as of FEBRUARY 12, 1999, the title
of STAR BANK, NATIONAL ASSOCIATION, CINCINNATI, OHIO, Charter No. 24, was
changed to "FIRSTAR BANK, NATIONAL ASSOCIATION."

As a result of the Garn-St. Germain Depository Institutions Act of 1982, the OCC
is no longer responsible for the approval of national bank name changes nor does
it maintain official records on the use of alternate titles. The use of other
titles or the retention of the rights to any previously used title is the
responsibility of the bank's board of directors. Legal counsel should be
consulted to determine whether or not the new title, or any previously used
title, could be challenged by competing institutions under the provisions of
federal and state law.

Sincerely,


/s/ David J. Rogers
National Bank Examiner


                                                                               4
