                           installments on the six-month, 12-month and 18-month

                           shall be subordinated to (x) the existing senior
                           indebtedness of the Buyer in the original aggregate
                           principal amount of $116 million and (y) the
                           indebtedness proposed to be incurred by the Buyer in

                           amounts of their respective Allocable Portions of
                           $2.8 million, which amounts shall be payable in three
                           equal installments on the six-month, 12-month and 18-
                           month anniversaries of the Closing Date, and which
                           notes shall be subordinated to (x) the existing
                           senior indebtedness of the Buyer in the original
                           aggregate principal amount of $116 million and (y)

and (viii), if, between the date hereof and the Effective Time, the outstanding
shares of Buyer Stock shall have been changed into a different number of shares
or a different class by reason of any stock dividend, subdivision,
reclassification, recapitalization, split, combination or exchange of shares, or
if any extraordinary dividend or distribution is made with respect to the Buyer
Stock, then the Stock Consideration shall be correspondingly adjusted to reflect
such stock dividend, subdivision, reclassification, recapitalization, split,
combination or exchange of shares, extraordinary dividend, distribution or other
similar event.

                           ix.      BUYER SHARES. Each share of Buyer Stock

                  e.       NET WORKING CAPITAL ADJUSTMENT.

                           i.       For purposes of the Closing, the Target
shall estimate the amount of its Net Working Capital as of the Closing Date on
the basis of the most current information then available. The Target shall
notify the Buyer of its calculation of the Target's estimated Net Working
Capital (the "ESTIMATED NET WORKING CAPITAL") and deliver a copy of such
calculation to the Buyer at least three, but not more than five, business days
prior to Closing. The Cash Consideration to be paid at the Closing shall be
adjusted based upon the Estimated Net Working Capital as follows:

                  (1)      If the Estimated Net Working Capital is less than $18
                           million, the Cash Consideration to be paid at Closing
                           shall be decreased by the difference between
                           $18,000,000 less the Estimated Net Working Capital;

                  (2)      If the Estimated Net Working Capital is equal to $18
                           million, there shall be no Cash Consideration
                           adjustment pursuant to this Section 2(e).

                  (3)      If the Estimated Net Working Capital is greater than
                           $18 million, the Cash Consideration to be paid at
                           Closing shall be increased by the difference between
                           the Estimated Net Working Capital less $18,000,000.

                           ii.      Within ten (10) business days following the
Closing, the Buyer shall deliver to the Principal Stockholder, for and on behalf
of all the Closing Stockholders, its calculation of the Target's Net Working
Capital as of the Closing Date (the "FINAL NET WORKING CAPITAL") and related
supporting documentation. Within 10 business days following his receipt of the
Buyer's Final Net Working Capital calculation, the Principal Stockholder shall
have the right to object in writing thereto, setting forth a specific
description of his objections. If the Principal Stockholder does not so object
during such period, the Principal Stockholder shall be deemed to have agreed,
for and on behalf of all the Closing Stockholders, to the Final Net Working
Capital calculation. If the Principal Stockholder so objects and the Buyer and
the Principal Stockholder cannot mutually agree on the Final Net Working Capital
calculation within five business days of Purchaser's receipt of the Principal
Stockholder's objections, the dispute shall be promptly submitted to the
Independent Firm, except as otherwise agreed by the Buyer and the Principal
Stockholder.

                           iii.     Based upon the Final Net Working Capital, as
finally determined pursuant to Section 2(e) hereof, the following post-Closing
deliveries shall be made, as applicable:

                  (1)      If the Final Net Working Capital is greater than the
                           Estimated Net Working Capital, the Buyer shall
                           deliver to the Closing Stockholders separate
                           certified checks, bank checks or wire transfer
                           payments of cash in the amounts of their respective
                           Allocable Portions of the amount equal to the
                           difference between the Final Net Working Capital,
                           less the Estimated Net Working Capital, together with
                           interest accrued from the Closing Date until and
                           including the date of such payments at the fixed rate
                           of 10% per annum. Simultaneously therewith, the Buyer
                           also shall deliver to the Closing Stockholders
                           payments under the Closing Notes of principal in the
                           amounts of their respective Allocable Portions of
                           $500,000, plus accrued interest under the Closing
                           Notes with respect to such payments of principal;

                  (2)      If the Final Net Working Capital is less than the
                           Estimated Net Working Capital, the Buyer shall be
                           entitled to receive from each Closing Stockholder a
                           payment in the amount of such Closing Stockholder's
                           Allocable Portion of the amount equal to the
                           difference between the Estimated Net Working Capital,

                           including the date of such payment at the fixed rate
                           of 10% per annum (the "WORKING CAPITAL ADJUSTMENT").
                           Each such payment shall be effected by a reduction,
                           effective as of the Closing Date, in the principal
                           amount of the Closing Note issued to such Closing
                           Stockholder in an amount (the "Reduction Amount")
                           equal to (x) the amount of such Closing Stockholder's
                           Allocable Portion of the Working Capital Adjustment,

                           the Closing Notes of principal in the amounts of

                           accrued interest under the Closing Notes with respect
                           to such payments of principal.

has been since its inception, qualified under Code Section 401(a), and its
related trust is, and has been since its inception, exempt from taxation under

                           vii.     With respect to each Employee Benefit Plan
that the Target or any ERISA Affiliate maintains or has maintained during the
prior six years or to which any of them contributes, or has been required to
contribute during the prior six years:

                  (1)      No action, suit, proceeding, claim, hearing or
investigation with respect to such Employee Benefit Plan (other than routine
claims for benefits) is pending or, to the Knowledge of the Stockholders,
threatened and, to the Knowledge of the Stockholders, no facts or circumstances
exist which could give rise to an action, suit, proceeding, claim, hearing or
investigation which, if asserted, would result in a Material Adverse Effect on
the Target;

                  (2)      No application, proceeding or other matter is pending
before the Internal Revenue Service, the Department of Labor or any other
governmental agency; and

                  (3)      The Target has not incurred, and will not incur, any
direct or indirect liability to the PBGC or otherwise under Title IV of ERISA
(including any withdrawal liability).

                           viii.    Neither the Target nor its ERISA Affiliates
(nor their predecessors) have ever contributed to, otherwise participated in or
in any way, directly or indirectly, have any liability with respect to any
Employee Benefit Plan which is subject to Title IV of ERISA or any Multiemployer
Plan. No "accumulated funding deficiency" (within the meaning of Code Section
412 or ERISA Section 302) has been or could be expected to be incurred (whether
or not waived) and no excise or other taxes have been or could be expected to be
incurred or are due because of any failure to comply with the minimum funding
standards of the Code or ERISA. No security under Code Section 401(a)(29) has
been or could be expected to be required and the assets of the Target are not,
and have not been, subject to any lien under ERISA or the Code. With respect to
each such Employee Benefit Plan, individually and in the aggregate, no event has
occurred and, to the Knowledge of Stockholders, there exists no condition or
facts or circumstances which would result in or could reasonably be expect to
result a Material Adverse Effect on the Target.

                           ix.      With respect to each such Employee Benefit
Plan which is an "employee benefit plan" within the meaning of ERISA Section
3(3) or which is a "plan" within the meaning of Code Section 4975(e), there has
occurred no transaction which is prohibited by ERISA Section 406 or which
constitutes a "prohibited transaction" under Code Section 4975(c) and with
respect to which a prohibited transaction exemption is not currently in effect
(except for transactions which, individually or in the aggregate, would not have
a Material Adverse Effect on the Target) and the consummation of the transaction
contemplated by this Agreement will not constitute or directly or indirectly
result in such a "prohibited transaction."

                           x.       The Target has complied in all material
respects with the provisions of Code Section 4980B with respect to each such
Employee Benefit Plan which is a group health plan within the meaning of Code
Section 5001(b)(1). Neither the Target nor its ERISA Affiliates maintain,
contribute to, or are obligated under any plan, contract, policy or arrangement
providing health or death benefits (whether or not insured) to current or former
employees or other personnel beyond the termination of their employment or other
services (other than pursuant to Code Section 4980B).


                                       18

<PAGE>

                           xi.      Each such Employee Benefit Plan may be
unilaterally terminated and/or amended by the Target at any time and no event,
circumstance or condition exists that would prevent any such amendment or
termination. The consummation of the transaction contemplated by this Agreement
will not (either alone or in conjunction with another event, such as a
termination of employment or other services) entitle any employee or other
person to receive severance or other compensation which would not otherwise be
payable absent the consummation of the transaction contemplated by this
Agreement or cause the acceleration of the time of payment or vesting of any
award or entitlement under any Employee Benefit Plan. Neither the Target nor its
ERISA Affiliates, or any officer or employee thereof, have made any promises or
commitments, whether legally binding or not, to create any additional plan,
agreement, or arrangement, or to modify or change any existing Employee Benefit
Plan. Neither the Target nor its ERISA Affiliates have any unfunded liabilities
pursuant to any Employee Pension Benefit Plan that is not intended to be
qualified under Code Section 401(a).

                           xii.     No person other than a Stockholder or a
Closing Stockholder has any right, title or interest in, or with respect to, the
Target Shares held in the ESOP by the Trustee. The Target Shares held in the
ESOP by the Trustee have been properly allocated among the ESOP participants and
beneficiaries in accordance with the provisions of the ESOP and applicable law.
There are no outstanding share acquisition loans under, or relating to, the
ESOP.

                  v.       ENVIRONMENTAL, HEALTH, AND SAFETY MATTERS.

                           i.       The Target is in compliance with
Environmental, Health, and Safety Requirements, except for such noncompliance as
would not have a Material Adverse Effect on the Target.

                           ii.      The Target has not received any written
notice, report or other information regarding any actual or alleged material
violation of Environmental, Health, and Safety Requirements, or any material
liabilities or potential material liabilities (whether accrued, absolute,
contingent, unliquidated or otherwise), including any investigatory, remedial or
corrective obligations, relating to the Target or any of its facilities arising
under Environmental, Health, and Safety Requirements, the subject of which is
reasonably likely to have a Material Adverse Effect on the Target.

                  w.       BOOKS AND RECORDS. All minute books and stock records
of the Target have been made available to the Buyer.

                  x.       NET CAPITAL. The Target is, and since November 1,
1996 has continuously been, in material compliance with SEC Rule 15c3-1 and NYSE
Rule 104 regarding its net capital and net liquid assets requirements.

                  y.       INSURANCE. The Target has insurance coverage with
reputable insurers for the Target's operations in amounts and covering such
risks as the Target reasonably believes necessary, in accordance with its
regular insurance practices.

                  z.       LABOR MATTERS. The Target is not a party to or
otherwise bound by any collective bargaining agreement, contract or other
agreement or understanding with a labor union or labor organization, nor, as of
the date hereof, is the Target the subject of any proceeding asserting that the
Target has committed an unfair labor practice or seeking to compel it to bargain
with any labor union or labor


                                       19

<PAGE>

organization nor, as of the date of this Agreement, is there pending or, to the
Knowledge of the Target or any Stockholder, threatened, any material labor
strike, dispute, walkout, work stoppage, slow-down or lockout involving the
Target.

                  aa.      NO ILLEGAL OR IMPROPER TRANSACTIONS. Neither the
Target nor any of its directors, officers, employees, or, to the Knowledge of
the Target or any Stockholder, agents or Affiliates, has directly or indirectly
used funds or other assets of the Target or made any promise or undertaking in
such regard, for (i) illegal contributions, gifts, entertainment or other
expenses relating to political activity; (ii) illegal payments to or for the
benefit of officials or employees of any Governmental Entity; (iii) illegal
payments to or for the benefit of, including the sharing of profits with, any
person, firm, corporation or other entity, or any director, officer, employee,
agent or representative thereof; or (iv) the establishment or maintenance of a
secret or unrecorded fund; and there have been no false or fictitious entries
made in the books or records of the Target with respect to any of the foregoing.

                  bb.      BANK ACCOUNTS. TARGET'S DISCLOSURE SCHEDULE contains
a true, correct and complete list of the names, locations and account
information of all banks, trust companies, savings and loan associations and
other financial institutions at which the Target maintains safe deposit boxes or
accounts of any nature (other than brokerage accounts maintained in the ordinary
course of business).

                  cc.      RELATED PARTY TRANSACTIONS. No current or former
officer or director (including their respective family members), employee or
stockholder, or any associate (as defined in the rules promulgated under the
Securities Exchange Act of 1934, as amended) of the Target, is presently, or, in
the last three years has been, (a) a party to any transaction with the Target
other than on an arms-length basis (including, without limitation, any contract,
agreement or other arrangement providing for the furnishing of services by, or
rental of real or personal property from, or otherwise requiring payments to,
any such officer or director (including their respective family members),
employee, stockholder or associate) or (b) to the Knowledge of the Target or any
Stockholder, the direct or indirect owner of an interest in any corporation,
firm, association or business organization which is a present (or potential)
competitor of the Target, other than an interest of not more than an aggregate

national securities exchange or traded in the over-the-counter market.

                  dd.      FAIRNESS OPINION. The Target has received the written
opinion of Legg Mason Wood Walker, Incorporated, to the effect that, as of the
date hereof, the Merger Consideration to be paid to the Closing Stockholders is
fair, from a financial point of view, to the Target and the holders of Target
Shares.

                  ee.      ADDITIONAL TAX MATTERS. The liabilities of the Target
to be assumed by the Buyer in the Merger and the liabilities to which the
transferred assets of the Target are subject at the Effective Time are and will
have been incurred in the ordinary course of business within the meaning of the
applicable Treasury Regulations. No shares of capital stock of the Target have
been (or, prior to the Effective Time, will be) redeemed prior to or in
connection with the Merger, and the Target has not made (and, prior to the
Effective Time, will not make) any extraordinary distribution (with the meaning

         4.       REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS. Each of

Restated Certificate of Incorporation, as amended). The Stockholder is not a
party to any voting trust, proxy or other agreement or understanding with
respect to the voting of any capital stock of the Target, other than those
referred to in the last sentence of Section 3(e) which are hereby waived to the
extent set forth in Section 3(e) and, with respect to the Trustee, other than
pursuant to the terms of the ESOP.

         5.       REPRESENTATIONS AND WARRANTIES OF THE BUYER. The Buyer
represents and warrants to the Target and the Stockholders that the statements
contained in this Section 5 are correct and complete as of the date of this

set forth in the BUYER'S DISCLOSURE SCHEDULE.

                  a.       ORGANIZATION, QUALIFICATION, AND CORPORATE POWER. The
Buyer is a corporation duly organized, validly existing, and in good standing
under the laws of the jurisdiction of its incorporation. Each of the Buyer's
Subsidiaries is a corporation, limited liability company or partnership duly
organized, validly existing, and in good standing under the laws of the
jurisdiction of its incorporation. Each of the Buyer and the Buyer's
Subsidiaries is duly authorized to conduct business and is in good standing
under the laws of each jurisdiction where such qualification is required, except
where the lack of such qualification would not have a Material Adverse Effect on
the Buyer and its Subsidiaries taken as a whole. Each of the Buyer and the
Buyer's Subsidiaries has full corporate or other organizational power and


                                       21

capital stock have been duly authorized, are validly issued, fully paid, and
nonassessable. Except for this Agreement, there are no outstanding or authorized
options, warrants, purchase rights, subscription rights, conversion rights,
exchange rights, or other contracts or commitments that could require the Buyer
to issue, sell, or otherwise cause to become outstanding any of its capital
stock. There are no outstanding or authorized stock appreciation, phantom stock,
profit participation, or similar rights with respect to the Buyer.

                  c.       AUTHORIZATION OF TRANSACTION. The Buyer has full
power and authority (including full corporate power and authority) to execute
and deliver this Agreement and to perform its obligations hereunder. This
Agreement and the other documents contemplated hereby to which they are parties
(assuming execution and delivery by the Target and the Stockholders) constitute
the valid and legally binding obligation of the Buyer, enforceable in accordance
with its terms and conditions, except as the enforceability thereof may be
limited by bankruptcy, insolvency or similar laws affecting creditors' rights
generally or by general principles of equity, whether considered in a proceeding
in equity or at law. The Buyer is not required to give any notice to, make any
filing with, or obtain any authorization, consent, or approval of any government
or governmental agency in order for the Parties to consummate the transactions
contemplated by this Agreement, except where the failure to give notice, to
file, or to obtain any authorization, consent, or approval would not have a
Material Adverse Effect on the Buyer and its Subsidiaries taken as a whole.

                  d.       NONCONTRAVENTION. The execution, delivery and
performance of this Agreement and the other documents contemplated hereby, and
the consummation by the Buyer of the transactions contemplated hereby, do not
and will not (i) violate any constitution, statute, regulation, rule,
injunction, judgment, order, decree, ruling, charge or other restriction of any
government, governmental agency or court to which the Buyer, or any of the
Buyer's Subsidiaries is subject or any provision of the Buyer's charter or
bylaws or the similar organizational documents of any of the Buyer's
Subsidiaries or (ii) conflict with, result in a breach of, constitute a default
under, result in the acceleration of, create in any party the right to
accelerate, terminate, modify, or cancel, or require any notice under any
agreement, contract, lease, license, instrument or other arrangement to which
the Buyer or any of the Buyer's Subsidiaries is a party or by which the Buyer or
any of the Buyer's Subsidiaries is bound or to which any of its assets is
subject (or result in the imposition of any Security Interest upon any of its
assets), except where the conflict, breach, default, acceleration, termination,
modification, cancellation, failure to give notice or Security Interest would
not have a Material Adverse Effect on the Buyer and its Subsidiaries taken as a
whole.

                  e.       BROKERS' FEES. None of the Buyer and the Buyer's
Subsidiaries has any liability or obligation to pay any fees or commissions to
any broker, finder, or agent with respect to the transactions contemplated by
this Agreement for which the Target or the Stockholders could become liable or
obligated.

                  f.       REGULATORY MATTERS. LaBranche & Co., a Subsidiary of
the Buyer, is and has been duly registered as a broker-dealer with the SEC and
in the states where such registration is required under


                                       22


<PAGE>



the securities laws of such states. LaBranche & Co. is and has been duly
registered as a NYSE specialist. LaBranche & Co. and its employees are in
compliance with all federal and state laws and NYSE rules regulating
broker-dealers or specialists or requiring registration, licensing or
qualification as a broker-dealer or specialist, and LaBranche & Co. is a member
in good standing and has all material licenses and authorizations in
self-regulatory or trade organizations or registered clearing agencies required
to permit the operation of its business as presently conducted. Each such
federal, state and NYSE registration is in full force and effect. The Buyer has
furnished to the Target a true, correct and complete copy of LaBranche & Co.'s
Form BD, as amended to date, filed by LaBranche & Co. with the SEC.

                  g.       TAXES. Each of the Buyer and the Buyer's Subsidiaries
has timely filed or will timely file all Tax Returns that it was required or
will be required to file, and has paid all Taxes shown thereon as owing, except
where failure to file such Tax Returns or to pay such Taxes would not have a
Material Adverse Effect on the Buyer and its Subsidiaries taken as a whole. All
such Tax Returns of the Buyer and the Buyer's Subsidiaries are, or will be when
filed, true, correct and complete in all material respects.

                  h.       ADDITIONAL TAX MATTERS. It is the present intention
of the Buyer to continue the historic businesses of the Target or use at least a
significant portion of the Target's historic business assets in a business, in
each case within the meaning of Treasury Regulation Section 1.368-1(d). The
Buyer does not have any plan or intention to sell, exchange, distribute,
transfer or otherwise dispose of any of the assets of the Target to be acquired
in the Merger, except for (i) dispositions made in the ordinary course of
business and (ii) transfers permitted by Section 368(a)(2)(C) of the Code or to
a member of the Buyer's qualified group (as defined in Section 1.368-1(d)(4) of
the Treasury Regulations).

                  i.       FILINGS WITH THE SEC. The Buyer has made all filings
with the SEC that it has been required to make under the Securities Act and the
Exchange Act (collectively, together with all of the Buyer's voluntary filings
with the SEC, the "PUBLIC REPORTS"). Each of the Public Reports has complied
with the Securities Act or the Exchange Act, as applicable, in all material
respects. None of the Public Reports, as of their respective dates, contained
any untrue statement of a material fact or omitted to state a material fact
necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading. The Buyer has
delivered to the Target a correct and complete copy of each Public Report
(together with all exhibits and schedules thereto and as amended to date).

                  j.       FINANCIAL STATEMENTS. The financial statements
included in the Public Reports (including the related notes and schedules) have
been prepared in accordance with GAAP applied on a consistent basis throughout
the periods covered thereby and present fairly the financial condition of the
Buyer and its Subsidiaries on a consolidated basis as of such dates and the
results of operations of the Buyer and its Subsidiaries on a consolidated basis
for such periods; PROVIDED, HOWEVER, that the interim statements are subject to
normal year-end adjustments and lack footnotes and other presentation items.

                  k.       EVENTS SUBSEQUENT TO THE BUYER'S MOST RECENT PUBLIC
REPORT. Since September 30, 1999, there has not been any Material Adverse Change
in the business, operations or financial condition of the Buyer or of the Buyer
and its Subsidiaries taken as a whole. Since September 30, 1999, (a) the
business of the Buyer and each of its Subsidiaries has been conducted in the
ordinary course and consistent with past practice and (b) no event has occurred
or fact or circumstance arisen that, individually or taken


                                       23

<PAGE>

together with all other events, facts and circumstances, has had or is
reasonably likely to have a Material Adverse Effect on the Buyer and its
Subsidiaries taken as a whole.

                  l.       LEGAL AND REGULATORY COMPLIANCE. Each of the Buyer
and the Buyer's Subsidiaries has complied with all applicable laws (including
rules, regulations, codes, plans, injunctions, judgments, orders, decrees,
rulings, and charges thereunder) of federal, state, local, and foreign
governments (and all agencies thereof) and all applicable rules and regulations
the NYSE, except where the failure to comply would not have a Material Adverse
Effect on the Buyer and its Subsidiaries taken as a whole.

                  m.       LITIGATION. Except as would not have a Material
Adverse Effect on the Buyer and its Subsidiaries taken as a whole either
individually or in the aggregate, there are no actions by or against, or
relating to the business of, the Buyer (i) pending before any court, arbitration
panel or any governmental or regulatory authority or (ii) to the Knowledge of
the Buyer, threatened to be brought by or before any court, arbitration panel or
any governmental or regulatory authority. The Buyer is not subject to any
governmental order (nor, to the Knowledge of the Buyer, are there any such
governmental orders threatened to be imposed by any governmental or regulatory
authority) which has had or is reasonably likely to have a Material Adverse
Effect on the Buyer and its Subsidiaries taken as a whole. There has not been
any action decided against or settled by the Buyer or any of its directors,
officers or employees during the last three (3) years in connection with the
Buyer's business which has had a Material Adverse Effect on the Buyer and its
Subsidiaries taken as a whole. The Buyer is not subject to any agreement or
instrument or subject to any judgment, order, writ, injunction, decree, rule,
regulation or ordinance (other than rules, regulations or ordinances that are
generally applicable to specialists) that has had or is reasonably likely to
have a Material Adverse Effect on the Buyer and its Subsidiaries taken as a
whole.

                  n.       FAIRNESS OPINION. The Buyer has received the written
opinion of Donaldson, Lufkin & Jenrette Securities Corporation to the effect
that, as of the date hereof, the Merger and the Merger Consideration to be paid
to the Closing Stockholders is fair, from a financial point of view, to the
Buyer and its stockholders.

                  o.       EMPLOYEE BENEFITS.

                           (i)      Each Employee Benefit Plan currently
maintained or contributed to by the Buyer (the "BUYER PLANS") (and each related
trust, insurance contract, or fund) complies in form and in operation in all
respects with the applicable requirements of ERISA and the Code, except where
the failure to comply would not have a Material Adverse Effect on the Buyer and
its Subsidiaries taken as a whole.

                           (A)      All contributions (including all employer
                  contributions and employee salary reduction contributions)
                  which are due have been paid to each Buyer Plan which is an
                  Employee Pension Benefit Plan.

                           (B)      Each Buyer Plan which is an Employee Pension
                  Benefit Plan has received a determination letter from the
                  Internal Revenue Service to the effect that it meets the
                  requirements of Code Section 401(a).

                           (C)      As of the last day of the most recent prior
                  plan year, the market value of assets under each Buyer Plan
                  which is an Employee Pension Benefit Plan (other than any


                                       24

the Target on or prior to the Closing and pay any and all Taxes due with respect

contrary treatment is required by applicable tax laws (or judicial or
administrative interpretations thereof). The Target shall provide the Buyer with
copies of such completed Tax Returns at least 10 days prior to the due date, and

                  e.       FULL ACCESS. Each of the Target and the Buyer will
permit representatives of the other to have full access at all reasonable times,
and in a manner so as not to unnecessarily interfere with the normal business
operations of the Buyer or the Target, as the case may be, to all premises,
properties, personnel, books, records (including tax records), contracts, and
documents of or pertaining to the Buyer or the Target, as the case may be.
Subject to the requirements of law or legal process, each of the Parties will
treat and hold as such any Confidential Information it receives from any other
Party in the course of the reviews contemplated by this Section 6(e), will not
use any of the Confidential Information except in connection with this Agreement
or as required by law or legal process, and, if this Agreement is terminated for
any reason whatsoever, will return to such Party all tangible embodiments (and
all copies) of the Confidential Information which are in its possession.

                  f.       NO TRANSFER OF THE SHARES. Each Stockholder agrees
that, without the Buyer's consent, which shall not unreasonably be withheld,
prior to the Closing, he or she will not sell, assign, transfer, gift, pledge or
otherwise dispose of, or otherwise agree to take such action with respect to,
his or her Target Shares. Notwithstanding the foregoing restriction, however,
(i) the Trustee shall be permitted to distribute Target Shares held in the ESOP
to the beneficiaries thereof in accordance with the terms of the ESOP and
applicable law, and (ii) a Stockholder shall be permitted to assign or transfer
his or her Target Shares prior to the Closing to an IRA in a rollover
contribution or as a result of his or her death or incapacity, provided that (1)
the Stockholder, or his duly authorized representative, promptly notifies the
Buyer in writing of such assignment or transfer in advance of such transfer, if
practicable, and (2) in the case of a rollover contribution to an IRA, such
transfer is limited to Target Shares allocated to the Stockholder by the ESOP.
Each Stockholder agrees that, in the event of any such permitted transfer, such
Stockholder will continue to be bound by all of his or her representations,
warranties, covenants and obligations under this Agreement.

                  g.       NOTICE OF DEVELOPMENTS.

                           i.       The Target will give prompt written notice
to the Buyer of any development causing a breach of any of the representations
and warranties contained in Sections 3 and 4 above.

                           ii.      The Buyer will give prompt written notice to
the Target of any development causing a breach of any of the representations and
warranties contained in Section 5 above or any failure to satisfy the condition
set forth in Section 8(c)(vi).

                  h.       EXCLUSIVITY. None of the Target or the Stockholders
will solicit or initiate the submission of any proposal or offer from any Person

consolidation, or share exchange).

                  i.       ESOP. The Target will effectuate the termination of
the ESOP and cause the Trustee to distribute all the assets of the ESOP in
accordance with the ESOP's terms and applicable law in a manner that will not

         7.       POST-CLOSING COVENANTS. The Parties agree as follows with
respect to the period following the Closing.


                                       27


<PAGE>

                  a.       GENERAL. In case at any time after the Closing any
further action is necessary or desirable to carry out the purposes of this
Agreement, each of the Parties will take such further actions (including the
execution and delivery of such further instruments and documents) as any other
Party reasonably may request, all at the sole cost and expense of the requesting
Party (unless the requesting Party is entitled to indemnification therefor under
Section 9 below).

                  b.       LITIGATION SUPPORT. In the event and for so long as
any Party actively is contesting or defending against any action, suit,
proceeding, hearing, investigation, charge, complaint, claim, or demand in
connection with (i) any transaction contemplated under this Agreement or (ii)
any fact, situation, circumstance, status, condition, activity, practice, plan,
occurrence, event, incident, action, failure to act, or transaction on or prior
to the Closing Date involving the Target, each of the other Parties shall
reasonably cooperate with it, him or her, or its, his or her counsel, in the
defense or contest, make available their personnel, and provide such testimony
and access to their books and records as shall be necessary in connection with
the defense or contest, all at the sole cost and expense of the contesting or
defending Party (unless the contesting or defending Party is entitled to
indemnification therefor under Section 9 below).

                  c.       NONCOMPETITION, NONSOLICITATION AND CONFIDENTIALITY.

                           i.       NONCOMPETITION. Each Stockholder
acknowledges that he or she has extensive knowledge and a unique understanding
of the business of the Target, has been directly involved with the establishment
and continued development of its customer relations and has had access to all of
the proprietary and Confidential Information used in the business of the Target.
Each Stockholder further acknowledges that if he or she, directly or indirectly,
were to compete with the Buyer or any of the Buyer's Subsidiaries in such
business following the Closing, the value associated with the Buyer's
acquisition of the Target and the goodwill of the Target would be adversely
affected. In furtherance of the Merger and to more effectively protect the value
of the Target and the Buyer, each Stockholder covenants and agrees that, for a
period beginning on the Closing Date and ending on the date which is two years
thereafter (the "TERM"), such Stockholder shall not, directly or indirectly, as
a sole proprietor, employee, agent, consultant, stockholder, director, partner
or in any other individual or representative capacity, act, or own, operate,
manage, control, engage in, invest in, or participate in, act as a consultant or
advisor to, render services for (alone or in association with any Person), or
otherwise assist any Person that engages in or owns, operates, manages or
controls a Person which acts as a specialist or otherwise makes a market in any
stock for which the Buyer or any Subsidiary of the Buyer acts as a specialist as
of the Closing Date (other than stock of a successor by merger or acquisition if
the stock for which the Buyer or any Subsidiary of the Buyer acts as specialist
is issued by a company that is not the surviving publicly traded entity in such
a transaction), except on behalf of the Buyer or any of its Affiliates, unless
the Buyer ceases to act as a specialist for or make a market in such stock
voluntarily or as a result of regulatory action. Notwithstanding the foregoing,
nothing contained in this Section 7(c)(i) shall prohibit any Stockholder,
directly or indirectly, from owning not more than an aggregate of one percent
(1%) of any class of stock of any company which is listed on a national
securities exchange or traded in the over-the-counter market.

                           ii.      NONSOLICITATION. Each Stockholder agrees
that, during the Term, such Stockholder will not, directly or indirectly, as a
sole proprietor, employee, agent, consultant, principal or otherwise, solicit
for employment or otherwise seek to adversely influence or adversely alter the


                                       28

<PAGE>

relationship between the Buyer or any of its Affiliates and any person who is or
was an employee (other than clerical or administrative personnel) of the Buyer,
the Target or any of their respective Affiliates during the 365 days preceding
such solicitation, except on behalf of the Buyer or any of its Affiliates;
PROVIDED, HOWEVER, that (x) a general solicitation for employment contained in a
newspaper or other periodical shall not constitute a breach of this Section
7(c)(ii), and (y) the restriction on solicitation of an employee of the Buyer,
the Target or any of their respective Affiliates contained in this Section
7(c)(ii) shall not apply to the solicitation of an employee whose employment has
been terminated by the Buyer without cause.

                           iii.     CONFIDENTIALITY. After the Closing, each
Stockholder shall strictly maintain the confidentiality of all information,
documents and materials relating to the Target, except to the extent disclosure
of any such information is required by law or authorized by the Buyer. In the
event that any Stockholder reasonably believes after consultation with counsel
that he or she is required by law to disclose any confidential information
described in this Section 7(c)(iii), such Stockholder will (x) provide the Buyer
with prompt notice before such disclosure in order that the Buyer may attempt to
obtain a protective order or other assurance that confidential treatment will be
accorded to confidential information, and (y) cooperate with the Buyer in
attempting to obtain such order or assurance. The provisions of this Section
7(c)(iii) shall not apply to any information, documents or materials which are
in the public domain or shall come into the public domain, other than by reason
of default by any Stockholder or his or her Affiliate under this Agreement, or
becomes known in the industry through no wrongful act on the part of any
Stockholder or his or her Affiliate.

                           iv.      REMEDIES. The Stockholders agree that the
Buyer shall be entitled to specific performance of the provisions of this
Section 7(c). If a court of competent jurisdiction declares that any term or
provision of this Section 7(c) is invalid or unenforceable, the Parties agree
that the court making the determination of invalidity or unenforceability shall
have the power to reduce the scope, duration, or area of the term or provision,
to delete specific words or phrases, or to replace any invalid or unenforceable
term or provision with 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. This Agreement shall be enforceable as so modified after the
expiration of the time within which the judgment may be appealed.

                  d.       BUYER STOCK. Each certificate evidencing the Stock
Consideration will be imprinted with a legend substantially in the following
form:

                           "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE
                  NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
                  AMENDED (THE "ACT"), OR UNDER ANY STATE SECURITIES LAW AND MAY

                  COMPANY OF AN OPINION OF COUNSEL, REASONABLY SATISFACTORY TO

accordance with all applicable federal and state securities laws and (z) the
permitted transferee agrees in writing to be bound by the provisions of this
Section 7(e).

                  f.       TAX RETURNS. The Buyer shall be responsible for
filing or causing to be filed all Tax Returns required to be filed by or on
behalf of the Target after the Closing Date. To the extent any Taxes shown due
on such Tax Returns are indemnifiable by the Stockholders, such Tax Returns
shall be prepared in a manner consistent with prior practice, unless otherwise
required by applicable law. The Buyer shall provide the Principal Stockholder
with a draft of any such Tax Return at least fifteen (15) days prior to the due
date for filing such Tax Return (taking into account any applicable extensions),
and the Principal Stockholder may provide the Buyer with written comments on
such draft Tax Return within five (5) business days after his receipt of such
draft. The Buyer and the Principal Stockholder shall attempt to resolve any
disputes regarding such draft Tax Return in good faith at least five (5)
business days prior to the due date for filing such Tax Return, but if the Buyer
and the Principal Stockholder cannot resolve any dispute regarding such draft
Tax Return at least five (5) business days prior to the due date for filing such
Tax Return, the dispute shall be promptly submitted to the Independent Firm,
except as otherwise agreed by the Buyer and the Principal Stockholder.

                  g.       INDEMNIFICATION OF DIRECTORS AND OFFICERS. From and
after the Effective Time, the Buyer will indemnify each individual who served as
a director or officer of the Target at any time prior to the Effective Time from
and against any and all Adverse Consequences resulting from, arising out of,
relating to, in the nature of, or caused by any matters existing or occurring at
or prior to the Effective Time (excluding this Agreement or any of the
transactions contemplated herein) to the fullest extent such individual would
have been indemnified as a director or officer of the Target prior to the
Effective Time and as then permitted under applicable law, PROVIDED, HOWEVER,
that nothing contained in this Section 7(g) shall in any manner be deemed to
affect the indemnification obligations of the Target and the Stockholders set
forth in Section 9 hereof.

                  h.       ESOP INDEMNIFICATION. In addition to (but without
duplication of) the Buyer's rights under Section 9 below, from and after the
Effective Time, each Stockholder (other than the Trustee) will indemnify Buyer
from and against his or her Allocable Portion of any and all Adverse
Consequences resulting from, arising out of, relating to, or caused by the ESOP.

                           vi.      assuming the transactions contemplated by
the Stock Purchase Agreement, dated as of December 23, 1999 (as may be amended
from time to time, the "Henderson Agreement"), by and among the Buyer, Henderson

Effect on the Buyer and its Subsidiaries taken as a whole;

                           vii.     any other documents and instruments as the

                  b.       INDEMNIFICATION PROVISIONS FOR BENEFIT OF THE BUYER.

                           i.       In the event the Target or any Stockholder
breaches any of its representations or warranties contained in Section 3 hereof
or any of its covenants contained herein, and if there is an applicable survival
period pursuant to Section 9(a) hereof, PROVIDED that the Buyer makes a written
claim for indemnification against the Stockholders pursuant to Section 11(h)
hereof within such survival period, then each Stockholder shall indemnify the
Buyer from and against his or her Allocable Portion of any Adverse Consequences
the Buyer shall suffer through and after the date of the claim for
indemnification caused by the breach; PROVIDED, HOWEVER, that no Stockholder
shall have any obligation to indemnify the Buyer from and against any Adverse
Consequences caused by the breach of any representation, warranty or covenant of
the Target (1) until the Buyer has suffered Adverse Consequences by reason of
all such breaches in excess of (x) a $25,000 aggregate deductible in the case of
one or more breaches of any of the representations and warranties contained in
Section 3(n) and (u) hereof, and (y) a $200,000 aggregate deductible in the case
of all other breaches (after which points each Stockholder will be obligated to
indemnify the Buyer only from and against his or her Allocable Portion of any
further such Adverse Consequences), and (2) to the extent the Adverse
Consequences the Buyer has suffered by reason of all such breaches of
representations and warranties (other than those contained in Section 3(n) and
(u) hereof) exceeds his or her Allocable Portion of $5,000,000 (excluding the
$200,000 aggregate deductible), after which point no Stockholder will be
obligated to indemnify the Buyer from and against any further such Adverse
Consequences (other than those caused by a breach of any representation or
warranty contained in Section 3(n) and (u)).

                           ii.      In the event any of the Stockholders
breaches any of his or her representations or warranties in Section 4 above or
any of his or her covenants contained herein, and, if there is an applicable
survival period pursuant to Section 9(a) above, PROVIDED that the Buyer makes a
written claim for indemnification against the Stockholder pursuant to Section
11(h) below within such survival period, then such Stockholder shall indemnify
the Buyer from and against the entirety of any Adverse Consequences the Buyer
shall suffer through and after the date of the claim for indemnification caused
by the breach.

                  c.       INDEMNIFICATION PROVISIONS FOR BENEFIT OF THE
STOCKHOLDERS.

                           i.       In the event the Buyer breaches any of its
representations, warranties or covenants contained herein, and, if there is an
applicable survival period pursuant to Section 9(a) above, PROVIDED that any of
the Stockholders or the Principal Stockholder on behalf of all of the
Stockholders makes a written claim for indemnification against the Buyer
pursuant to Section 11(h) below within such survival period, then the Buyer
shall indemnify each of the Stockholders from and against the entirety of any
Adverse Consequences the Stockholder shall suffer through and after the date of
the claim for indemnification caused by the breach; PROVIDED, HOWEVER, that the
Buyer shall not have any obligation to indemnify the Stockholders from and
against any Adverse Consequences caused by the breach of any representation,
warranty or covenant of the Buyer (1) until the Stockholders have suffered
Adverse Consequences by reason of all such breaches in excess of a $200,000
aggregate deductible (after which point the Buyer will be obligated only to
indemnify the Stockholders from and against any further such


                                       34

<PAGE>

Adverse Consequences), and (2) to the extent the Adverse Consequences the
Stockholders have suffered by reason of all such breaches exceeds $5,000,000
(excluding the aggregate deductible).

                           ii.      The Buyer shall indemnify the Stockholders
against any income Tax imposed on them (following a final determination (within
the meaning of Section 1313 of the Code)) as a result of the Merger not
qualifying as a reorganization under Section 368(a) of the Code by reason of any
action or inaction on the part of the Buyer subsequent to the Effective Time.

                  d.       DAMAGES IN THE EVENT OF TERMINATION. In the event
this Agreement is terminated pursuant to Section 10(a) hereof, each of the
Target and the Buyer agrees that it will seek damages only from the other for
any Adverse Consequences to it caused by the other's (or, in the case of Adverse
Consequences to the Buyer, any of the Stockholders') breach prior to such
termination of any of the other's (or, in the case of Adverse Consequences to
the Buyer, any of the Stockholders') representations, warranties or covenants
contained herein.

                  e.       MATTERS INVOLVING THIRD PARTIES.

                           i.       If any third party shall notify any Party
(the "INDEMNIFIED PARTY") with respect to any matter (a "THIRD PARTY CLAIM")
which may give rise to a claim for indemnification against any other Party (the
"INDEMNIFYING PARTY") under this Section 9, then the Indemnified Party shall
promptly (and in any event within five business days after receiving notice of
the Third Party Claim) notify each Indemnifying Party thereof in writing;
PROVIDED that the failure of the Indemnified Party to give notice as provided
herein shall not relieve the Indemnifying Party of its obligations under this
Section 9, except and only to the extent the Indemnifying Party's ability to
defend against, mitigate or diminish the amount of such claim is materially
prejudiced by such failure.

                           ii.      Any Indemnifying Party will have the right
at any time to assume and thereafter conduct the defense of the Third Party
Claim with counsel of his or her choice reasonably satisfactory to the
Indemnified Party; PROVIDED, HOWEVER, that the Indemnifying Party will not
consent to the entry of any judgment or enter into any settlement with respect
to the Third Party Claim without the prior written consent of the Indemnified
Party (not to be withheld unreasonably) unless the judgment or proposed
settlement involves only the payment of money damages and does not impose an
injunction or other equitable relief upon the Indemnified Party; PROVIDED,
FURTHER, the Indemnified Party shall have the right to employ separate counsel
to participate in the defense of any such Third Party Claim or litigation to
which the Indemnified Party is a party, but the fees and expenses of such
counsel shall be at the expense of the Indemnified Party unless (i) the
employment of such counsel shall have been authorized in writing by the
Indemnifying Party in connection with the defense of such action, (ii) the
Indemnifying Party shall not have employed counsel reasonably satisfactory to
the Indemnified Party to take charge of the defense of such action within a
reasonable time after notice of the institution of such action, (iii) the
Indemnified Party shall have reasonably concluded that there may be material
defenses available to it that are different from or additional to those
available to the Indemnifying Party or (iv) the use of counsel chosen by the
Indemnifying Party to represent the Indemnified Party would present such counsel
with a conflict of interest (in which case the Indemnifying Party shall not have
the right to direct the defense of such action on behalf of the Indemnified
Party), in any of which events the reasonable fees and expenses of such counsel
shall be borne by the Indemnifying Party and paid as incurred.

<PAGE>

                           iii.     Unless and until an Indemnifying Party
assumes the defense of the Third Party Claim as provided in Section 9(e)(ii)
above, however, the Indemnified Party may defend against the Third Party Claim
in any manner he or she reasonably may deem appropriate.

                           iv.      In no event will the Indemnified Party
consent to the entry of any judgment or enter into any settlement with respect
to the Third Party Claim without the prior written consent of each of the
Indemnifying Parties (not to be withheld unreasonably).

                  f.       DETERMINATION OF ADVERSE CONSEQUENCES. The Parties
shall make appropriate adjustments for tax benefits and insurance coverage in
determining Adverse Consequences for purposes of this Section 9. If any
indemnification payment under this Section 9 is determined to be taxable to the
Indemnified Party by any taxing authority, the Indemnifying Party shall also
indemnify the Indemnified Party for any Adverse Consequences resulting from the
receipt of such payment. All indemnification payments under this Section 9
(except any which represent interest) shall be deemed adjustments to the Merger
Consideration.

         10.      TERMINATION.

                  a.       TERMINATION OF AGREEMENT. Certain of the Parties may
terminate this Agreement as provided below:

                           i.       the Buyer, the Target and the Principal
Stockholder may terminate this Agreement by mutual written consent at any time
prior to the Effective Time;

                           ii.      the Buyer may terminate this Agreement by
giving written notice to the Target and the Principal Stockholder at any time
prior to the Effective Time (1) in the event the Target or any of the
Stockholders has breached any material representation, warranty or covenant
contained in this Agreement in any material respect (without giving effect to
any materiality qualifiers contained therein), the Buyer has notified the Target
and the Principal Stockholder of the breach, and the breach has continued
without cure for a period of 15 days after the notice of breach or (2) if the
Closing shall not have occurred on or before March 23, 2000 by reason of the
failure of any condition precedent under Section 8(b) hereof (unless the failure
results primarily from the Buyer breaching any representation, warranty or
covenant contained in this Agreement);

                           iii.     the Target or the Principal Stockholder may
terminate this Agreement by giving written notice to the Buyer at any time prior
to the Effective Time (1) in the event the Buyer has breached any material
representation, warranty or covenant contained in this Agreement in any material
respect (without giving effect to any materiality qualifiers contained therein),
the Target or the Principal Stockholder has notified the Buyer of the breach,
and the breach has continued without cure for a period of 15 days after the
notice of breach or (2) if the Closing shall not have occurred on or before
March 23, 2000 by reason of the failure of any condition precedent under Section
8(c) hereof (unless the failure results primarily from the Target or any of the
Stockholders themselves breaching any representation, warranty or covenant
contained in this Agreement); and


                                       36

<PAGE>

                           iv.      the Target or the Principal Stockholder may
terminate this Agreement by giving written notice to the Buyer prior to the
Closing in the event the Closing Value is less than $8.00 per share.

                  b.       EFFECT OF TERMINATION. If any Party terminates this
Agreement pursuant to Section 10(a) above, all rights and obligations of the
Parties hereunder shall terminate without any liability of any Party to any
other Party (except for any liability of any Party then in breach); PROVIDED,
HOWEVER, that the confidentiality provisions contained in Section 6(e) shall
survive any such termination.

         11.      MISCELLANEOUS.

                  a.       NATURE OF CERTAIN OBLIGATIONS.

                  i.       The representations and warranties of each of the
Stockholders in Section 4 hereof and the covenants of each of the Stockholders
contained herein are several obligations. This means that the particular
Stockholder making the representation, warranty, or covenant will be solely
responsible only to the extent provided in Section 9 above for any Adverse
Consequences the Buyer may suffer as a result of any breach thereof.

                  ii.      The representations and warranties of the Target and
the Stockholders contained in Section 3 hereof are joint obligations. This means

above for his or her Allocable Portion of any Adverse Consequences the Buyer may
suffer as a result of any breach thereof.

                  b.       PRESS RELEASES AND PUBLIC ANNOUNCEMENTS. No Party
shall issue any press release or make any public announcement relating to the
subject matter of this Agreement prior to the Closing without the prior written
approval of the Buyer, the Target and the Principal Stockholder; PROVIDED,
HOWEVER, that any Party may make any public disclosure that such party believes
in good faith is required by applicable law or any listing or trading agreement
concerning publicly-traded securities (in which case
the disclosing Party will use its reasonable best efforts to advise the other
Parties prior to making the disclosure).

                  c.       NO THIRD-PARTY BENEFICIARIES. This Agreement shall
not confer any rights or remedies upon any Person other than the Parties and
their respective successors and permitted assigns, PROVIDED, HOWEVER, that the
provisions of Section 7(g) hereof are intended for the benefit of the
individuals referred to therein and their respective legal representatives.

                  d.       ENTIRE AGREEMENT. This Agreement (including the
documents referred to herein) constitutes the entire agreement among the Parties
and supersedes any prior understandings, agreements or representations by or
among the Parties, written or oral, to the extent they have related in any way
to the subject matter hereof.

                  e.       SUCCESSION AND ASSIGNMENT. This Agreement shall be
binding upon and inure to the benefit of each of the Parties named herein,
including the Closing Stockholders, and their respective successors and
permitted assigns. No Party may assign either this Agreement or any of its, his
or her rights,


                                       37

<PAGE>

interests, or obligations hereunder without the prior written approval of the

Buyer may (i) assign any or all of its rights and interests hereunder to one or
more of its Affiliates and (ii) designate one or more of its Affiliates to
perform its obligations hereunder (in any or all of which cases the Buyer
nonetheless shall remain responsible for the performance of all of its
obligations hereunder), and any Stockholder may assign any or all of his or her
rights and interests hereunder to the extent permitted by the express terms of
this Agreement.

                  f.       COUNTERPARTS. This Agreement may be executed in one
or more counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

                  g.       HEADINGS. The section headings contained in this
Agreement are inserted for convenience only and shall not affect in any way the

         EXHIBIT A - Closing Note for Holders of Class A Target Shares


                                PROMISSORY NOTE


[$______]                                                      February __, 2000


        FOR VALUE RECEIVED, the undersigned, LaBranche & Co Inc., a Delaware
corporation (the "MAKER"), hereby agrees to pay to __________________(the
"PAYEE") the principal amount of _______________DOLLARS ($____________) (the
"PRINCIPAL AMOUNT") [which is the Payee's Allocable Portion of $3,000,000],
plus interest payable at the fixed rate of 10% per annum. This note is being
executed in connection with the Agreement and Plan of Merger ("MERGER
AGREEMENT") entered into as of January 25, 2000 by and among the Maker, Webco
Securities, Inc, a Delaware corporation ("WEBCO"), and each other person
executing the Merger Agreement on the signature pages thereof. Capitalized
terms used herein and not otherwise defined herein shall have the respective
meanings ascribed thereto in the Merger Agreement.

        A.       All payments of the Principal Amount and any interest accrued
with respect thereto shall be made to the Payee at the following times, in
the following amounts and subject to the following terms and conditions:

                 1.       $__________ [which is the Payee's Allocable Portion of
        $500,000], plus the amount of all accrued and unpaid interest with
        respect thereto, shall be paid by the Maker to the Payee by certified
        or bank check or wire transfer two business days after the final
        determination of Final Net Working Capital in accordance with
        Section 2(e)(ii) of the Merger Agreement, PROVIDED, HOWEVER, that if
        the Final Net Working Capital is less than the Estimated Net Working
        Capital, the Principal Amount shall be deemed to have been reduced as
        of the date hereof by an amount equal to the Payee's Allocable
        Portion of the difference between the Estimated Net Working Capital
        less the Final Net Working Capital;

                 2.       $__________  [which is the Payee's Allocable Portion
        of $2,500,000], plus the amount of all accrued and unpaid interest
        with respect thereto, shall be paid by the Maker to the Payee by
        certified of bank check or wire transfer on the date which is 18
        months from the date hereof (the "MATURITY DATE"), PROVIDED, HOWEVER,
        that such amount shall be deemed to have been reduced as of the date
        hereof by the amount of any indemnification payments from the Payee
        to which the Maker is entitled pursuant to, and in accordance with,
        Section 9 of the Merger Agreement. For purposes of determining
        whether and to what extent the Principal Amount shall be reduced
        under this Paragraph A(2), the following procedures shall apply:

                          (a)      Prior to the Maturity Date, the Maker shall
                 give written notice (each, a "CLAIM NOTICE") to the
                 Principal Stockholder and the Payee specifying in reasonable
                 detail the nature and dollar amount of any claim as to which
                 indemnification is sought by the Maker under the Merger
                 Agreement (each, a "CLAIM"). The Maker

<PAGE>

                 may make more than one Claim with respect to any underlying
                 set of facts;

                          (b)      Any objection by the Principal Stockholder
                 to a particular Claim Notice (an "OBJECTION") shall be in
                 writing, shall set forth in reasonable detail the grounds
                 for such objection and must be received by the Maker within
                 ten (10) business days after the date of receipt of such Claim
                 Notice;

                          (c)      If the Maker does not receive from the
                 Principal Stockholder an Objection within ten (10) business
                 days from the date of receipt of such Claim Notice, the
                 Principal Amount shall be deemed to have been reduced as of
                 the date hereof by the Payee's Allocable Portion of the
                 amount specified in the Claim Notice;

                          (d)      If the Maker receives from the Principal
                 Stockholder an Objection within ten (10) business days from
                 the receipt of such Claim Notice, the amount of such Claim
                 shall be deemed to be in dispute to the extent set forth in
                 such Objection (each, a "DISPUTED AMOUNT"). If such
                 Objection does not dispute the entire amount of the Claim
                 Notice, the Principal Amount shall be deemed to have been
                 reduced as of the date hereof by the Payee's Allocable
                 Portion of the amount of the undisputed portion of such
                 Claim Notice;

                         (e)       On the Maturity Date, the Maker shall pay
                 to the Payee by certified or bank check or wire transfer the
                 then-remaining Principal Amount, plus the amount of all
                 accrued and unpaid interest with respect thereto, less the
                 sum of (i) the Payee's Allocable Portion of the aggregate
                 Disputed Amounts, (ii) the Payee's Allocable Portion of the
                 aggregate amount of all other pending Claims for which Claim
                 Notices have been delivered by the Maker pursuant to
                 Paragraph A(2)(a) above (each, a "PENDING CLAIM") and (iii)
                 the legal and other expenses incurred by the Principal
                 Stockholder in representing the Payee in connection herewith
                 or in connection with the Merger Agreement, as determined by
                 the Principal Stockholder and acknowledged to the Maker in
                 writing by the Payee, which expenses shall be paid by the
                 Maker directly to the Principal Stockholder, on behalf of
                 the Payee, for remittance to the appropriate creditor; and

                          (f)      Thereafter, all Disputed Amounts and
                 Pending Claims shall be resolved in accordance with the
                 Merger Agreement, and, as each such Disputed Amount and
                 Pending Claim is resolved, either (i) the remaining unpaid
                 Principal Amount represented by the Payee's Allocable
                 Portion of such Disputed Amount or Pending Claim, plus the
                 amount of all accrued and unpaid interest with respect
                 thereto,


                                      -2-

<PAGE>

                 shall be paid by the Maker to the Payee by certified or bank
                 check or wire transfer within two business days after such
                 resolution, to the extent such Disputed Amount or Pending
                 Claim is resolved in favor of the Payee, and/or (ii) the
                 Principal Amount shall be deemed to have been reduced as of
                 the date hereof by the remaining unpaid Principal Amount
                 represented by the Payee's Allocable Portion of such
                 Disputed Amount or Pending Claim is resolved in favor of the
                 Maker.

        B.       Any amount payable hereunder which is not paid when due in
accordance with the terms and conditions hereof shall bear interest until
paid at a rate which is 1.5% per annum higher than the interest rate
otherwise applicable hereunder.

        C.       The Maker shall have the right to prepay this Note in whole
at any time or in part from time to time without premium or penalty.

        D.       Each of the following events shall constitute an "Event of
Default" for purposes hereof;

                 1.       FAILURE TO PAY NOTE.  Default in the payment of the
        principal of, or any interest on, this Note when the same shall have
        become due and payable and the default continues for a period of five
        business days thereafter;

                 2.       FAILURE TO PAY OTHER INDEBTEDNESS. Default by the
        Maker or any other entity controlled by the Maker within the meaning
        of Rule 2 of the New York Stock Exchange (a "SUBSIDIARY") under any
        indebtedness for borrowed money (other than indebtedness of any
        Subsidiary or of the Maker in either case to any other Subsidiary),
        and such default is either (a) caused by the failure to make any
        payment of principal or interest due on such indebtedness within any
        applicable grace period, or (b) results in the acceleration of such
        indebtedness prior to the stated maturity thereof, PROVIDED,
        HOWEVER,that the provisions of this Paragraph D(2) shall not apply to
        any indebtedness which does not exceed $1,000,000 in the aggregate
        and which is not material to the operations of the Maker and its
        Subsidiaries; and

                 3.       INSOLVENCY OR BANKRUPTCY. The Maker or any

        the Maker or any Subsidiary shall make an assignment for the benefit
        of creditors or a composition with creditors, shall be generally
        unable to pay its debts as such debts become due or shall file a
        petition commencing a voluntary case concerning the Maker or any
        Subsidiary under any chapter of Title 11 of the United States Code
        entitled "Bankruptcy," or an involuntary case shall be commenced
        against the Maker or any Subsidiary under any such chapter and relief
        is ordered against the Maker or any Subsidiary or the petition is
        controverted but is not dismissed within 60 days after the
        commencement of the case, or the Maker or any Subsidiary shall
        petition or apply to any tribunal for the appointment of any
        receiver, liquidator, custodian or trustee of or for it or any

        substantial part of its property, or shall commence any proceeding
        relating to the Maker or any Subsidiary under any bankruptcy,
        reorganization, arrangement, readjustment of debt, receivership,
        dissolution or liquidation law or statute of any jurisdiction,
        whether now or hereafter in effect, or if there is commenced against
        the Maker or any Subsidiary any such proceeding which remains
        undismissed for a period of 60 days, or an order, judgment or decree
        approving the petition in any such proceeding shall be entered, or
        the Maker or any Subsidiary by any act or failure to act indicates
        its consent to, approval of or acquiescence in any such proceeding or
        the appointment of any receiver, liquidator, custodian or trustee of
        or for it or any substantial part of its property, or suffered any
        such appointment to continue undischarged or unstayed for a period of
        60 days, or the Maker or any Subsidiary shall take any corporate

        FOR VALUE RECEIVED, the undersigned, LaBranche & Co Inc., a Delaware

"PAYEE") the principal amount of _______________DOLLARS ($____________) (the
"PRINCIPAL AMOUNT") [which is the Payee's Allocable Portion of $3,000,000],
plus interest payable at the fixed rate of 10% per annum. This note is being
executed in connection with the Agreement and Plan of Merger ("MERGER
AGREEMENT") entered into as of January 25, 2000 by and among the Maker, Webco
Securities, Inc., a Delaware corporation ("WEBCO"), and each other person
executing the Merger Agreement on the signature pages thereof. Capitalized
terms used herein and not otherwise defined herein shall have the respective
meaning ascribed thereto in the Merger Agreement.

        A.       All payments of the Principal Amount and any interest accrued
with respect thereto shall be made to the Payee at the following times, in
the following amounts and subject to the following terms and conditions:

                 1.       $__________ [which is the Payee's Allocable Portion of
        $500,000], plus the amount of all accrued and unpaid interest with
        respect thereto, shall be paid by the Maker to the Payee by certified
        or bank check or wire transfer two business days after the final

        Section 2(e)(ii) of the Merger Agreement, PROVIDED, HOWEVER, that if
        the Final Net Working Capital is less than the Estimated Net Working
        Capital, the Principal Amount shall be deemed to have been reduced as
        of the date hereof by an amount equal to the Payee's Allocable
        Portion of the difference between the Estimated Net Working Capital
        less the Final Net Working Capital;

                 2.       $__________  [which is the Payee's Allocable Portion
        of $2,500,000], plus the amount of all accrued and unpaid interest
        with respect thereto, shall be paid by the Maker to the Payee by
        certified or bank check or wire transfer on the date which is 18
        months from the date hereof (the "MATURITY DATE"), PROVIDED, HOWEVER,
        that such amount shall be deemed to have been reduced as of the date
        hereof by the amount of any indemnification payments from the Payee
        to which the Maker is entitled pursuant to, and in accordance with,
        Section 9 of the Merger Agreement. For purposes of determining
        whether and to what extent the Principal Amount shall be reduced
        under this Paragraph A(2), the following procedures shall apply:

                          (a)      Prior to the Maturity Date, the Maker shall
                 give written notice (each, a "CLAIM NOTICE") to the Payee
                 specifying in reasonable detail the nature and dollar amount
                 of any claim as to which indemnification is sought by the
                 Maker under the Merger Agreement (each, a "CLAIM"). The
                 Maker may make more than one Claim with respect to any
                 underlying set of facts;

<PAGE>

                          (b)      Any objection by the Payee to a particular
                 Claim Notice (an "OBJECTION") shall be in writing, shall set
                 forth in reasonable detail the grounds for such objection
                 and must be received by the Maker within ten (10) business
                 days after the date of receipt of such Claim Notice;

                          (c)      If the Maker does not receive from the
                 Payee an Objection within ten (10) business days from the
                 date of receipt of such Claim Notice, the Principal Amount
                 shall be deemed to have been reduced as of the date hereof
                 by the Payee's Allocable Portion of the amount specified in
                 the Claim Notice;

                          (d)      If the Maker receives from the Payee an
                 Objection within ten (10) business days from the date of
                 receipt of such Claim Notice, the amount of such Claim shall
                 be deemed to be in dispute to the extent set forth in such
                 Objection (each, a "DISPUTED AMOUNT"). If such Objection
                 does not dispute the entire amount of the Claim Notice, the
                 Principal Amount shall be deemed to have been reduced as of
                 the date hereof by the Payee's Allocable Portion of the
                 amount of the undisputed portion of such Claim Notice;

                          (e)      On the Maturity Date, the Maker shall pay
                 to the Payee by certified or bank check or wire transfer the
                 then-remaining Principal Amount, plus the amount of all
                 accrued and unpaid interest with respect thereto, less the
                 sum of (i) the Payee's Allocable Portion of the aggregate
                 Disputed Amounts and (ii) the Payee's Allocable Portion of
                 the aggregate amount of all other pending Claims for which
                 Claim Notices have been delivered by the Maker pursuant to
                 Paragraph A(2)(a) above (each a "PENDING CLAIM"); and

                          (f)      Thereafter, all Disputed Amounts and
                 Pending Claims shall be resolved in accordance with the
                 Merger Agreement, and, as each such Disputed Amount and
                 Pending Claim is resolved, either (i) the remaining unpaid
                 Principal Amount represented by the Payee's Allocable
                 Portion of such Disputed Amount or Pending Claim, plus the
                 amount of all accrued and unpaid interest with respect
                 thereto, shall be paid by the Maker to the Payee by
                 certified or bank check or wire transfer within two business
                 days after such resolution, to the extent such Disputed
                 Amount or Pending Claim is resolved in favor of the Payee,
                 and/or (ii) the Principal Amount shall be deemed to have
                 been reduced as of the date hereof by the remaining unpaid
                 Principal Amount represented by the Payee's Allocable
                 Portion of such Disputed Amount or Pending Claim, to the
                 extent such Disputed Amount or Pending Claim is resolved in
                 favor of the Maker.

shall remove the foregoing legend from the certificate or issue to such Holder a
new certificate therefor free of any transfer legend, if (x) with such request,
the Company shall have received either the opinion referred to in Section 3
hereof stating that any transfer by such Holder of the Restricted Securities
evidenced by such certificate will not violate the Securities Act and applicable
state securities laws, or (y) in accordance with paragraph (k) of Rule 144, such
Holder is not and has not during the last three months been an affiliate of the
Company and such Holder has held the Restricted Securities represented by such
certificate for a period of at least two years. The Company will use its best
efforts to assist any Holder in complying with the provisions of this Section 2
for removal of the legend set forth above.

         3.       NOTICE OF PROPOSED TRANSFERS. The Holder of each certificate
representing Stockholder Shares by acceptance thereof agrees to comply in all
respects with the provisions of this Agreement. Except as otherwise permitted by
the Merger Agreement, prior to any proposed transfer of any Restricted
Securities (other than under circumstances described in Section 4 hereof), the
Holder thereof shall give written notice to the Company of such Holder's
intention to effect such transfer. Each such notice shall describe the manner
and circumstances of the proposed transfer in detail, and shall be accompanied
(except in transactions in compliance with Rule 144) by a written opinion of
legal counsel who shall be satisfactory to the Company, addressed to the Company
and reasonably satisfactory in form and substance to the Company's counsel,
stating that the proposed


                                       3

<PAGE>

transfer of the Restricted Securities may be effected without registration under
the Securities Act and applicable state securities laws, whereupon the Holder of
such Restricted Securities, subject to Section 7(e) of the Merger Agreement,
shall be entitled to transfer such Restricted Securities in accordance with the
terms of the notice delivered by the Holder to the Company. Each certificate
evidencing the Restricted Securities transferred as provided above shall bear
the appropriate restrictive legend set forth above, unless the opinion of
counsel referred to above further states that no such legend is required in
order to establish compliance with any provisions of the Securities Act or
applicable state securities laws.

         4.       REGISTRATION RIGHTS.

         4.1      (a)      REQUEST FOR REGISTRATION. Pursuant to this
Section 4.1(a), at any time after the Company becomes eligible to register
shares of Common Stock with the Commission pursuant to a registration statement
on Form S-3, the Initiating Holder shall be entitled to present to the Company
one written request (the "Stockholder Request") that the Company effect a
registration of Registrable Securities held by some or all of the Stockholders;
PROVIDED, HOWEVER, that the Initiating Holder shall have no obligation to
present the Stockholder Request unless at least 100,000 shares of Registrable
Securities in the aggregate are covered by such request. In addition, in the
event of the death of William E. Boye, Jr. prior to the first anniversary of the
date hereof, the Initiating Holder shall be entitled to present to the Company
one written request (the "Boye Estate Request") that the Company effect a
registration of all or a portion of the Boye Estate Shares, but in no event
shall the Company be required to effect such registration prior to its becoming
eligible to register shares of Common Stock with the Commission pursuant to a
registration statement on Form S-3 .

                  If the Company shall receive from the Initiating Holder a
Request that the Company effect any registration with respect to all or a part
of the Registrable Securities, the Company will use its reasonable best efforts
to effect a Demand Registration as soon as practicable after receipt of the
Request (including, without limitation, the execution of an undertaking to file
post-effective amendments, appropriate qualification under applicable blue sky
or other state securities laws (except that the Company shall not be required to
qualify the offering under the blue sky laws of any jurisdiction in which the
Company would be required to execute a general consent to service of process
unless the Company is already subject to service in such jurisdiction) and
appropriate compliance with applicable regulations issued under the Securities
Act) as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Registrable Securities as are
specified in such request; PROVIDED that, after the Company has effected a
Demand Registration pursuant to the Stockholder Request, the Initiating Holder
may not make any further Stockholder Requests; and PROVIDED, FURTHER, that,
after the Company has effected a Demand Registration pursuant to the Boye Estate
Request, the Initiating Holder may not make any further Boye Estate Requests.

                  The registration statement filed pursuant to a Request of the
Initiating Holder may, subject to the provisions of Section 4.1(b) below,
include other securities of the Company which are held by officers or directors
of the Company or which are held by persons who, by virtue of


                                       4

<PAGE>

agreements with the Company, are entitled to include their securities in any
such registration (collectively, "Other Stockholders") and may include
securities of the Company being sold for the account of the Company.

                  (b)      UNDERWRITING. If all or any portion of the
Registrable Securities covered by a Request are, at the request of the
Initiating Holder, to be distributed by means of an underwriting, the Initiating
Holder shall so advise the Company as a part of the Request. Any underwriter
selected by the Initiating Holder shall be subject to the Company's approval.

                  The Company shall (together with all Holders and Other
Stockholders proposing to distribute their securities through such underwriting)
enter into an underwriting agreement in customary form with the underwriter or
representative of the underwriters. Notwithstanding any other provision of this
Section 4.1, if the representative of the underwriters advises the Initiating
Holder in writing that, in the opinion of the underwriters, marketing factors
require a limitation on the number of shares to be underwritten, the Company
shall so advise the Initiating Holder, and the number of shares of Registrable
Securities and other securities that may be included in the registration and
underwriting shall be allocated in the following manner: (i) the securities
being sold for the account of the Company shall be excluded from such
registration and underwriting to the extent required by such limitation, and
(ii) if a limitation on the number of shares is still required, the securities
held by Other Stockholders of the Company shall be excluded from such
registration and underwriting to the extent required by such limitation in
proportion, as nearly as practicable, to the respective amounts of securities
requested to be registered by such Other Stockholders, and (iii) if a limitation
on the number of shares is still required, the securities being sold for the
account of the Holders shall be excluded from such registration and underwriting
to the extent required by such limitation, in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities and other
securities which the Initiating Holder had requested to be included in such
registration. If the Company, the Initiating Holder or any Other Stockholder who
has requested inclusion in such registration as provided above disapproves of
the terms of the underwriting, such person may elect to withdraw therefrom by
written notice to the Company, the underwriter and the Initiating Holder. The
securities so withdrawn shall also be withdrawn from registration.

                  (c)      The Company shall have the right to defer a Request
of the Initiating Holder to effect a Demand Registration for up to seventy-five
(75) calendar days if, in the Company's good faith judgment, effecting a
registration would be seriously detrimental to the Company, or material
nonpublic information about the Company exists and the Board concludes as a
result, that it would not be in the Company's best interest to file such
registration statement at such time.

         4.2      COMPANY REGISTRATION.

                  (a)      If, at any time after the Company becomes eligible to
register shares of Common Stock with the Commission pursuant to a registration
statement on Form S-3, the Company shall determine to register any of its
securities either for its own account or the account of a security holder or
holders exercising their respective demand registration rights (other than a
registration


                                       5

<PAGE>

relating solely to employee benefit plans, a registration relating solely to a
Commission Rule 145 transaction or a registration on any registration form which
does not permit secondary sales), the Company will:

                           (i)      promptly within ten (10) days of such
determination give to each Holder written notice thereof; and

                           (ii)     include in such registration and in any
underwriting involved therein, all the Registrable Securities specified in a
written request or requests, made by any Holder within twenty (20) days after
receipt of the written notice from the Company described in clause (i) above,
except as set forth in Section 4.2(b) below. Such written request may specify
all or a part of a Holder's Registrable Securities.

                  (b)      UNDERWRITING. If the registration of which the
Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise the Holders by written notice. All
Holders proposing to distribute their Registrable Securities through such
underwriting shall (together with the Company distributing its securities for
its own account through such underwriting) enter into an underwriting agreement
in customary form with the underwriter or underwriters selected by the Company.
Notwithstanding any other provision of this Section 4.2, if the representative
of the underwriters advises the Company in writing that, in its opinion,
marketing factors require a limitation on the number of shares to be
underwritten, the Company shall so advise all Holders requesting registration,
and the number of shares that may be included in the registration and
underwriting shall be allocated first to the Company for securities being sold
for its account and then in the following manner: (i) the securities requested
to be registered by officers or directors of the Company shall be excluded from
such registration and underwriting to the extent required by such limitation in
proportion, as nearly as practicable, to the respective amounts of securities
requested to be registered by such officers and directors, and (ii) if a
limitation on the number of shares is still required, the securities being sold
for the account of the Holders and Other Stockholders shall be excluded from
such registration and underwriting to the extent required by such limitation in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities and other securities which they had requested to be included in such
registration. If any Holder or Other Stockholder who has requested inclusion in
such registration as provided above disapproves of the terms of the
underwriting, such person may elect to withdraw therefrom by written notice to
the Company and the underwriter.

         4.3      EXPENSES OF REGISTRATION.

                  (a)      The Company shall bear all Registration Expenses and
the selling Holders shall bear all Selling Expenses (in proportion, as nearly as
practicable, to the Registrable Securities of each Holder being registered)
incurred in connection with any registration, qualification or compliance
pursuant to the provisions of Section 4.1 or 4.2.


                                       6

<PAGE>

         4.4      REGISTRATION PROCEDURES. In the case of each registration
effected by the Company pursuant to this Agreement, the Company will keep each
Holder advised in writing as to the initiation of each registration and as to
the completion thereof. At its expense, the Company will:

                  (a)      Keep such registration effective for a period of one
hundred twenty (120) days or until the Holder or Holders have completed the
distribution described in the registration statement relating thereto, whichever
first occurs; PROVIDED, HOWEVER, that in the case of any registration of
Registrable Securities on Form S-3 which are intended to be offered on a
continuous or delayed basis, such 120-day period shall be extended, if
necessary, to keep the registration statement effective until all such
Registrable Securities are sold, PROVIDED that Rule 415, or any successor rule
under the Securities Act, permits an offering on a continuous or delayed basis,
and PROVIDED further that applicable rules under the Securities Act governing
the obligation to file a post-effective amendment permit, in lieu of filing a
post-effective amendment which (x) includes any prospectus required by Section
10(a)(3) of the Securities Act or (y) reflects facts or events representing a
material or fundamental change in the information set forth in the registration
statement, the incorporation by reference of information required to be included
in (x) and (y) above to be contained in periodic reports filed pursuant to
Section 13 or 15(d) of the Exchange Act in the registration statement;

                  (b)      Prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Securities Act with respect to the disposition of
securities covered by such registration statement;

                  (c)      Furnish such number of prospectuses and other
documents incident thereto, including any term sheet or any amendment of or
supplement to the prospectus, as a selling Holder from time to time may
reasonably request;

                  (d)      Notify each seller, at its last known addresses as
set forth in the Company's books and records, of Registrable Securities covered
by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or incomplete in the light of the
circumstances then existing, and at the request of any such seller, prepare and
furnish to such seller a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchaser of such shares, such prospectus shall not include 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 not misleading or
incomplete in the light of the circumstances then existing;

                  (e)      Cause all Registrable Securities included in such
registration to be listed on each, if any, securities exchange or system on
which similar securities issued by the Company are then listed;


                                       7

<PAGE>

                  (f)      Make reasonably available for inspection by any
seller of Registrable Securities, any underwriter participating in any
disposition pursuant to such registration statement, and any attorney or
accountant retained by any such seller or underwriter, all financial and other
records, pertinent corporate documents and properties of the Company, and cause
the Company's officers and directors to supply all information reasonably
requested by any such seller, underwriter, attorney or accountant in connection
with such registration statement; PROVIDED, HOWEVER, that such seller,
underwriter, attorney or accountant shall agree to hold in confidence and trust
all information so provided;

                  (g)      At the request of any underwriter in connection with
an underwritten offering, furnish an opinion of counsel for the Company, dated
the effective date of the registration statement, and "comfort" letters signed
by the Company's independent public accountants who have examined and reported
on the Company's financial statements included in the registration statement, to
the extent permitted by the standards of the AICPA or other relevant
authorities, covering substantially the same matters with respect to the
registration statement (and the prospectus included therein) and (in the case of
the accountants' "comfort" letters) with respect to events subsequent to the
date of the financial statements, as are customarily covered in opinions of
issuer's counsel and in accountants' "comfort" letters delivered to the
underwriters in underwritten public offerings of securities; and

                  (h)      Otherwise use its reasonable best efforts to comply
with all applicable rules and regulations of the Commission, and make available
to its security holders, as soon as reasonably practicable, an earnings
statement covering the period of at least twelve months, but not more than
eighteen months, beginning with the first month after the effective date of the
registration statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Securities Act.

         5.       INDEMNIFICATION.

                  (a)      The Company will indemnify each Holder, each of its
officers, directors and partners, and each person controlling such Holder, with
respect to which registration, qualification or compliance has been effected
pursuant to Section 4 hereof, and each underwriter, if any, and each person who
controls any underwriter, against all claims, losses, damages and liabilities
(or actions, proceedings or settlements in respect thereof) arising out of or
based on any untrue statement (or alleged untrue statement) of a material fact
contained in any prospectus or other document (including any related
registration statement) incident to any such registration, qualification or
compliance, or based on any 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 will reimburse each such Holder, each of its
officers, directors and partners, and each person controlling such Holder, each
such underwriter and each person who controls any such underwriter, for any
legal and any other expenses as they are reasonably incurred in connection with
investigating and defending any such claim, loss, damage, liability or action,
PROVIDED that the Company will not be liable in any such case to the extent that
any such claim, loss, damage, liability or expense arises out of or is based on
any untrue statement or omission based upon written information furnished to the
Company by such


                                       8

<PAGE>

Holder or underwriter and stated to be specifically for use therein or to the
extent due to the failure of such Holder or underwriter to provide an updated
prospectus or other document to a purchaser at a time when the Company has
informed such Holder or underwriter of a material misstatement or omission in a
prospectus or other document and has provided updated prospectuses or other
documents correcting such misstatement or omission.

                  (b)      Each Holder will, if Registrable Securities held by
it are included in the securities as to which such registration, qualification
or compliance is being effected, indemnify the Company, each of its directors
and officers and each underwriter, if any, of the Company's securities covered
by such a registration statement, each person who controls the Company or such
underwriter within the meaning of the Securities Act and the rules and
regulations thereunder, each other Holder and each of their officers, directors
and partners, and each person controlling such Holder, against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement, prospectus or other document,
or any 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 will reimburse the Company and such Holders, directors, officers, partners,
persons, underwriters or control persons for any legal or any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus or other document in reliance upon and in conformity with written
information furnished to the Company by such Holder and stated to be
specifically for use therein.

                  (c)      Each party entitled to indemnification under this
Section 5 (the "Indemnified Party") shall give notice in writing to the party
required to provide indemnification (the "Indemnifying Party") promptly after
such Indemnified Party has actual knowledge of any claim as to which indemnity
may be sought, and shall permit the Indemnifying Party to assume the defense of
any such claim or any litigation resulting therefrom, PROVIDED that counsel for
the Indemnifying Party, who shall conduct the defense of such claim or any
litigation resulting therefrom, shall be approved by the Indemnified Party
(whose approval shall not unreasonably be withheld), and the Indemnified Party
may participate in such defense at such Indemnified Party's expense; PROVIDED,
however, that the Indemnifying Party shall pay the expense of one counsel for
all similarly situated Indemnified Parties if representation of such Indemnified
Parties by the counsel retained by the Indemnifying Party would be inappropriate
due to actual or potential differing interests between the Indemnified Parties
and any other party represented by such counsel in such proceeding, and PROVIDED
FURTHER that the failure of any Indemnified Party to give notice as provided
herein shall not relieve the Indemnifying Party of its obligations under this
Section 5, unless such failure materially prejudices the ability of the
Indemnifying Party to defend against the claims asserted against the Indemnified
Party. No Indemnifying Party, in the defense of any such claim or litigation,
shall, except with the consent of each Indemnified Party, consent to entry of
any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation,


                                       9

<PAGE>

and no Indemnified Party shall consent to entry of any judgment or settle such
claim or litigation without the prior written consent of the Indemnifying Party.
Each Indemnified Party shall furnish such information regarding itself or the
claim in question as an Indemnifying Party may reasonably request in writing and
as shall be reasonably required in connection with defense of such claim and
litigation resulting therefrom.

                  (d)      If the indemnification provided for in this Section 5
is unavailable to an Indemnified Party in respect of any losses, claims, damages
or liabilities referred to therein, then each 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 or
liabilities in such proportion as is appropriate to reflect the relative fault
of the Company on the one hand and the stockholders offering securities in the
offering (the "Selling Stockholders") on the other in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities, as well as any other relevant equitable considerations. The
relative fault of the Company on the one hand and the Selling Stockholders on
the other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or by the Selling Stockholders and the parties' relevant intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company and the Selling Stockholders agree that it would not be
just and equitable if contribution pursuant to this Section 5(d) were based
solely upon the number of entities from whom contribution was requested or by
any other method of allocation which does not take account of the equitable
considerations referred to above in this Section 5(d). The amount paid or
payable by an Indemnified Party as a result of the losses, claims, damages and
liabilities referred to above in this Section 5(d) shall be deemed to include
any legal or other expenses reasonably incurred by such Indemnified Party in
connection with investigating or defending any such action or claim, subject to
the provisions of Section 5(d) hereof. No person guilty of fraudulent
misrepresentation (within the meaning of the Securities Act) shall be entitled
to contribution from any person who was not guilty of such fraudulent
misrepresentation.

         6.       INFORMATION BY HOLDER. Each Holder shall furnish to the
Company such information regarding such Holder and the distribution proposed by
such Holder as the Company may reasonably request in writing and as shall be
reasonably required in connection with any registration, qualification or
compliance referred to in this Agreement.

         7.       "LOCK-UP" AGREEMENT. Each Holder, if requested by the Company
and the managing underwriter of an offering by the Company of Common Stock or
other securities of the Company pursuant to a registration statement, shall
agree not to sell publicly or otherwise transfer or dispose of any Stockholder
Shares or other securities of the Company held by such Holder (other than those
included in the registration) for a specified period of time (not to exceed one
hundred eighty (180) days) following the effective date of such registration
statement.


                                       10

<PAGE>

         8.       RULE 144 REPORTING. With a view to making available the
benefits of certain rules and regulations of the Commission which may permit the
sale of the Restricted Securities to the public without registration, the
Company agrees to:

                  (a)      use its reasonable best efforts to make and keep
public information available as those terms are understood and defined in Rule
144 under the Securities Act at all times from and after ninety (90) days
following the effective date of the first registration under the Securities Act
filed by the Company for an offering of its securities to the general public;

                  (b)      use its reasonable best efforts to file with the
Commission in a timely manner all reports and other documents required of the
Company under the Securities Act and the Exchange Act at any time after it has
become subject to such reporting requirements; and

                  (c)      so long as the Holders own any Restricted Securities,
furnish to the Holders forthwith upon request a written statement by the Company
as to its compliance with the reporting requirements of Rule 144 (at any time
from and after ninety (90) days following the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed as the Holders may reasonably request in availing themselves
of any rule or regulation of the Commission allowing the Holders to sell any
such securities without registration.

         9.       TRANSFER OR ASSIGNMENT OF REGISTRATION RIGHTS. The rights to
cause the Company to register securities granted to the Holders by the Company
under Section 4 may be transferred or assigned, PROVIDED that the Company is
given written notice at the time of or within a reasonable time after said
transfer or assignment, stating the name and address of said transferee or
assignee and identifying the Registrable Securities with respect to which such
registration rights are being transferred or assigned, and PROVIDED further that
the transferee or assignee of such rights assumes the obligations of the Holders
under this Agreement, and PROVIDED further that said transferee or assignee is
not a Competitor (as defined below) or an affiliate of a Competitor of the
Company. A "Competitor" shall mean any specialist on the New York Stock Exchange
or any other person or entity which acts as a market maker in securities and
which, now or in the future, competes directly with the Company or any of its
affiliates.

         10.      TERMINATION. Subject to Section 4.1(a), the provisions of
Sections 4.1 and 4.2 of this Agreement shall terminate on the first anniversary
of the Closing Date or, if Rule 144 is not available to any Holder(s) because
adequate current public information with respect to the Company required by Rule
144(c) is not available, at such later time as the Company advises such
Holder(s) that such public information is available or is no longer required to
be available in order for such Holder(s) to sell pursuant to Rule 144.


                                       11

<PAGE>

         11.      ACTION BY INITIATING HOLDER ON BEHALF OF EACH HOLDER.
Notwithstanding anything in this Agreement to the contrary, each Holder (i)
irrevocably constitutes and appoints the Initiating Holder as the true and
lawful agent and attorney-in-fact of such Holder with full power to appoint a
substitute or substitutes to act hereunder with respect to all matters arising
in connection with the transactions contemplated hereby, including presenting a
Stockholder Request under Section 4.1 hereof, and (ii) hereby directs and
authorizes the Initiating Holder, for and on behalf of such Holder and/or all
Holders, to execute and deliver all documents and to take all such other actions
and to make all such determinations as the Initiating Holder shall, in his sole
discretion, deem necessary or appropriate in connection with the transactions
contemplated by this Agreement, all such executed and delivered documents,
actions and determinations to be binding on such Holder and/or all Holders.

         12.      AMENDMENT; WAIVER. No amendment, alteration or modification of
this Agreement shall be valid unless in each instance such amendment, alteration
or modification is expressed in a written instrument executed by Holders who own
at least a majority of the Stockholder Shares. No waiver of any provision of
this Agreement shall be valid unless it is expressed in a written instrument
duly executed by the party or parties making such waiver; it being agreed and
understood that execution by Holders who own a majority of the Stockholder
Shares shall constitute a waiver by all the Stockholders. The failure of any
party to insist, in any one or more instances, on performance of any of the
terms and conditions of this Agreement shall not be construed as a waiver or
relinquishment of any rights granted hereunder or of the future performance of
any such term, covenant or condition but the obligation of any party with
respect thereto shall continue in full force and effect.

         13.      SPECIFIC PERFORMANCE. The parties hereby declare that it is
impossible to measure in money the damages which will accrue to a party hereto
by reason of a failure to perform any of the obligations under this Agreement.
Therefore, all parties hereto shall have the right to specific performance of
the obligations of the other parties under this Agreement, and if any party
hereto shall institute an action or proceeding to enforce the provisions hereof,
any person (including the Company) against whom such action or proceeding is
brought hereby waives the claim or defense therein that such party has an
