Section 3.10.Limitation on Asset Sales.

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



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 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.

(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 (3) of paragraph (a) (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

Holders,
with a copy to the Trustee, which notice shall govern the terms of such Net Proceeds Offer. Upon receiving such notice, 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 ratabasis based on the principal amount of Notes (and other Indebtedness for which a concurrent offer is being made as permitted by this Section 3.10) 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.

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).

(e)   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.

(f)    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 underSection 4.1the 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 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 3.10.

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 Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any securities laws or regulations

on apro ratabasis based on the principal amount of Notes of each series tendered. An Excess Proceeds Offer shall remain open for a period of 20
business days or such longer period as may be required by law.

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 made the Change of

in any such certificate previously delivered and not superseded.

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 otherwise deal with the Company or any of its Affiliates with
the same rights it would have if it were not Trustee. Any Paying Agent, Registrar or co-Registrar may do the same with like rights. However, the Trustee must comply with Section 7.10andSection 7.11.

Section 7.4.Trustee's Disclaimer.The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company's use of the proceeds from the Notes, and it shall not be responsible for any statement of

documents, costs of preparation and mailing of notices to Holders and reasonable costs of counsel retained by the Trustee in connection with the delivery of an Opinion of Counsel or otherwise, in

experts.

of enforcing this Indenture (including thisSection 7.7) and of defending itself against any claims (whether asserted by any Holder, the Company
or otherwise). The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its

be required to pay such fees and expenses if it assumes the Trustee's defense, and, in the reasonable judgment of
outside counsel to the Trustee, there is no conflict of interest between the

Company
and the Trustee in connection with such defense. The Company need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee through the Trustee's

amounts due under thisSection 7.7shall not be subordinate to any other liability or Indebtedness of the Company.

Company's payment obligations pursuant to thisSection 7.7shall survive the discharge of this Indenture and

Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Outstanding 2009 Senior Notes or 2012 Senior Notes,

(b)   If
the Trustee resigns or is removed by the Company or by the Holders of a majority in principal amount of the Outstanding 2009 Senior Notes or 2012 Senior Notes, as the
case may be, and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of the Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee.

(c)   A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon 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. The successor Trustee shall mail a notice of its
succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.7.

(d)   If
a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in

successor Trustee.

(e)   If
the Trustee fails to comply withSection 7.10, any Holder may petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

§ 310(b)(1) are met.

FORM OF REVERSE SIDE OF NOTE

[In the case of the 2009 Senior Notes:91/2% Senior Notes due 2009]
[In the case of the 2012 Senior Notes:11% Senior Notes due 2012]

LaBranche &
Co Inc., a Delaware corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to as the
"Company"), promises 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 November 15, 2004. Interest on this Note will accrue from the most
recent date to which interest has been paid on this Note or, if no interest has been paid, from May 18, 2004. The Company will pay interest on overdue principal (plus interest on such interest
to the extent lawful), at the rate borne by this Note to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

The
Company will 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 ("Defaulted Interest") without regard to any applicable grace periods at a rate equal to the rate shown on
this Note, as provided in the Indenture.

Prior
to 10:00 a.m., New York City time, on the date on which any principal of or interest on this Note is due and payable, the Company will irrevocably deposit with the Trustee
or the Paying Agent money sufficient to pay such principal and/or interest. The Company will pay interest (except Defaulted Interest) to the Persons who are registered Holders of Notes of this series
at the close of business on the Record Date preceding the Interest Payment Date even if Notes of this series are canceled, repurchased or redeemed after the Record Date and on or before the relevant
Interest Payment Date. Holders must surrender Notes of this series to a Paying Agent to collect principal payments. The Company will pay principal and interest in U.S. Legal Tender.

Payments
in respect of Notes of this series represented by a Global Note (including principal and interest) will be made by the transfer of immediately available funds to the accounts
specified by DTC. The Company will make all payments in respect of a Certificated Note (including principal and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on the Notes of this series may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount
of Notes of this series, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to
the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may
accept in its discretion).

Initially,
U.S. Bank National Association (the "Trustee"), will act as Trustee, Paying Agent and Registrar. The Company may appoint and
change any Paying Agent, Registrar or co-Registrar without notice to any Holder. The Company may act as Paying Agent, Registrar or co-Registrar.

The
Company issued this Note under an Indenture, dated as of May 18, 2004 (as it may be amended or supplemented from time to time in accordance with the terms thereof, the
"Indenture"),

Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as amended or supplemented from time to time.

The
Notes of this series are general unsecured obligations of the Company limited to [In the case of the 2009 Senior Notes,

Company may, at its option, use the net cash proceeds of one or more Public Equity Offerings to redeem up to 33% of the aggregate principal amount of the Notes of this series issued under the
Indenture at a redemption price equal to [In the case of the 2009 Senior Notes, add: 109.5%,in the case of the 2012

to require that the Company purchase all or a portion (in integral multiples of $1,000) of the Holder's Notes of this series at a purchase price equal to 101% of the principal amount thereof, plus
accrued and unpaid interest through the date of purchase. Within 30 days following the date upon which the Change of Control occurred, the Company must make a Change of Control Offer pursuant

Date, the Excess Proceeds received in the offering of the Notes to repurchase shares of the Company's Series B preferred stock outstanding as of the Issue Date, the Company will be required to
make an Excess Proceeds Offer to purchase, to the extent of the Excess Proceeds Offer Amount, from all Holders of Notes, on apro ratabasis, Notes at
101% of the principal amount thereof, plus accrued interest (if any) to the date of purchase, as more fully set forth in the Indenture.

The
Notes of this series are in fully registered form without coupons, and only in denominations of principal amount of $1,000 and any integral multiple thereof. A Holder may transfer or
exchange Notes of this series 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 of this series selected for redemption (except, in the case of
a Note of this series to be redeemed in part, the portion of such Note not to be redeemed) for a period beginning 15 days before the mailing of a notice of Notes of this series to be redeemed
and ending on the date of such mailing or (ii) any Notes of this series for a period beginning 15 days before an Interest Payment Date and ending on such Interest Payment Date.

The
registered holder of this Note may be treated as the owner of this Note for all purposes.

property law designates another Person. After any such payment, Holders of Notes of this series entitled to the money must look only to the Company and not to the Trustee for payment.

an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Outstanding Notes of this series may declare all the Notes of this
series to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which will result in the Notes of this series being due and payable immediately upon the
occurrence of such Events of Default.

Holders

An
incorporator, director, officer, employee, stockholder or controlling person, as such, of the Company shall not have any liability for any obligations of the Company or any successor
person thereof under the Notes of this series, the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note of this series, each
Holder of Notes of

A-6

This
Note shall be governed by, and construed in accordance with, the laws of the State of New York.
