information included in "Risk Factors" and the Consolidated Financial
Statements and Notes thereto appearing elsewhere in this Prospectus. This
Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including those set forth in "Risk Factors" and elsewhere in this Prospectus.
Unless otherwise indicated, (i) references in this Prospectus to the "Company"
mean, as appropriate, prior to the Reorganization (as defined below),
Roundtable Partners, L.L.C. and its subsidiaries, on a consolidated basis and,
after the Reorganization, Knight/Trimark Group, Inc. and its subsidiaries, on a
consolidated basis and (ii) references to "Common Stock" mean the Class A
Common Stock and the Class B Common Stock.
 
                                  THE COMPANY
 
  Knight/Trimark Group, Inc. is a leading market maker in NASDAQ securities,
other over-the-counter ("OTC") equity securities, and equity securities listed
on the New York Stock Exchange ("NYSE") and the American Stock Exchange
("AMEX") in the Third Market. The Company has attained this leadership position
by providing best execution services to broker-dealer and institutional
customers through its sophisticated trading systems and proprietary methods.
Through its wholly-owned subsidiary, Knight Securities, Inc. ("Knight"), the
Company makes markets in approximately 4,200 equity securities in NASDAQ and on
the OTC Bulletin Board of the National Association of Securities Dealers, Inc.
("NASD"). The Company, through its wholly-owned subsidiary, Trimark Securities,
Inc. ("Trimark"), makes markets in all NYSE- and AMEX-listed equity securities
in the Third Market.
 
  Since the beginning of 1997, Knight and Trimark have significantly increased
their market share of trading volume in each of their respective markets.
According to The AutEx Group ("AutEx"), Knight's advertised share volume in
NASDAQ increased from 614.7 million shares representing 4.4% of total market
share (or a rank of 6th overall) for the month of January 1997, to 1.2 billion
shares representing 8.1% of total market share (or a rank of 2nd overall) for
the month of December 1997, to 1.9 billion shares representing 9.9% of total
market share (or a rank of 1st overall) for the month of March 1998. According
to the NASD, Trimark's reported share volume of the NYSE-listed securities
increased from 234.2 million shares representing 21.2% of total NYSE Third
Market volume (or a rank of 1st overall) for the month of January 1997, to
338.4 million shares representing 30.5% of total NYSE Third Market volume (or a
rank of 1st overall) for the month of December 1997, to 445.6 million shares
representing 33.1% of total NYSE Third Market volume (or a rank of 1st overall)
for the month of March 1998. Trimark's reported share volume of AMEX-listed
securities increased from 40.2 million shares representing 51.4% of total AMEX
Third Market volume (or a rank of 1st overall) for the month of January 1997,
to 78.7 million shares representing 66.4% of total AMEX Third Market volume (or
a rank of 1st overall) for the month of December 1997, to 80.4 million shares
representing 68.9% of total AMEX Third Market volume (or a rank of 1st overall)
for the month of March 1998.
 
  During recent years, the U.S. market for equity securities has experienced
dramatic growth in trading volumes. The average daily volume of securities
traded in NASDAQ increased from 225.0 million shares in December 1992 to 678.5
million shares in December 1997. The average daily volume of securities traded
on the NYSE increased from 222.2 million shares in December 1992 to 546.9
million shares in December 1997. The average daily volume of securities traded
on the AMEX increased from 14.2 million shares in December 1992 to 28.0 million
shares in December 1997. During this period, the average daily trading volume
in the Third Market, which consists of trading NYSE- and AMEX-listed securities
in the OTC market, also increased significantly. The increase in trading volume
has resulted from a number of factors, including the growth of cash flows into
equity-based mutual funds, historic high returns in U.S. equity markets, the
emergence and market acceptance of discount brokers, technological innovations,
such as the emergence of the Internet, and reduced transaction costs.

  Changes in regulations governing the securities market, and to a lesser
extent, the move from securities being quoted in sixteenths rather than eighths
of a dollar, have dramatically reduced average spreads between bid and ask
prices. As a result, traditional brokerage firms are increasingly electing to
focus on their core competencies and to outsource their market-making functions
to independent market makers. In addition, Internet brokers, who are handling
increased trading volume, also utilize independent market makers. According to
AutEx, in March 1998, the three largest independent market makers represented a
combined market share of 25.4% of the trading volumes of OTC equity securities,
up from 17.2% in March 1997. Similarly, according to the NASD, in March 1998
the three largest Third Market trading firms represented a combined market
share of 58% of the Third Market volume in NYSE equity securities compared to
42% in June 1997. The three largest Third Market trading firms in AMEX listed
securities represented a combined market share of 75% in March 1998 compared to
55% in June 1997. While a large volume of trading provides an opportunity to
spread fixed costs over a larger number of trades, net profit per trade has
declined. As a result, certain independent market makers are seeking new
trading methodologies to identify and take advantage of the profit
opportunities represented by each trade. These market makers are also seeking
to increase order flow in an effort to increase the number of trades they
handle, which, in turn, will provide increased trading profit opportunities.
These market makers require efficient and sophisticated systems and risk
management practices and personnel with the requisite expertise to deliver
superior trade execution and customer service, while handling increased order
flow and maintaining low costs per trade.
 
  The Company provides best execution services to broker-dealer and
institutional customers through its sophisticated trading systems and
proprietary methods. The Company is committed to providing a value-added
execution methodology that emphasizes automated execution and rule compliance,
real-time information access to customers, and pricing plus liquidity
advantages based upon the Company's willingness to commit capital. The Company
believes that its highly skilled, experienced and entrepreneurial workforce is
uniquely positioned to provide high quality customer service. In addition, the
Company is currently implementing its proprietary electronic communications
gateway product, "e.Knight," which enables broker-dealer and institutional
customers to access the Knight and Trimark trading systems from their desktops
through the Internet and other electronic communications gateways. The Company
has made significant investments in technology to enable the efficient
processing of large volumes of order flow, without diminishing speed of
execution. The Company's systems are designed to process up to 500,000 trades
per day and in March, 1998, handled a combined average of 134,000 trades per
day. The Company's trading methodology focuses on the dynamic, real-time
analysis of market activity and price movements, which enables the Company to
better manage risk and quickly adjust its trading strategy in an effort to
maximize its trading profits.
 
  The Company's goal is to maintain and enhance its leadership position in the
market-making industry by (i) continuing to invest in leading technologies to
ensure that it has the capability to process greater trading volumes, (ii)
increasing order flow to enhance its position as a leading market maker and to
create additional profit opportunities, (iii) accelerating its penetration of
the market for institutional investors, which it believes provides an
opportunity for growth and offers higher profit margins, (iv) investing in
human capital, by aggressively recruiting and retaining high caliber personnel
to deliver best execution and high quality customer service, (v) developing new
services that address evolving customer and technological requirements to
establish new customer relationships, and (vi) creating customer awareness of
the link between Knight and Trimark to leverage customer satisfaction in one
market to increased use of the Company's services in other markets.
 
  The Company's marketing strategy is to continue to differentiate itself from
competitors by enhancing its reputation and brand as the provider of highest
quality execution solutions with superior customer service. The Company's
target customers are national and regional full-service broker-dealers,
electronic discount brokers and institutional investors. Certain of the
Company's customers include Ameritrade, Brown & Company, Discover Brokerage,
E*TRADE, Merrill Lynch, PaineWebber, Waterhouse Securities, and many leading
financial institutions.

                     CERTAIN TRANSACTIONS AND RELATIONSHIPS
 
  The Reorganization and Certain Transactions. The Company was organized in
April 1998 for the purpose of succeeding to the business of Roundtable
Partners, L.L.C. (the "LLC"). Concurrent with the closing of the Offering,
based on an assumed initial public offering price of $15.00 per share, all of
the member interests of the LLC will be exchanged for 41,000,000 shares of
Common Stock of the Company. Certain members of the LLC, including management,
who have so elected, will receive 1,741,581 additional shares of Class A Common
Stock valued at the initial public offering price with respect to their share
of the undistributed income of the LLC through March 31, 1998 (the
"Undistributed Profits"). Management of the Company has elected to receive
shares of Class A Common Stock for all of its Undistributed Profits. The
Company will receive no additional consideration in connection with such
conversion of member interests into shares of Common Stock. In connection with
the exchange, Knight will become the successor entity to Knight Securities,
L.P., and Trimark will become the successor entity to Trimark Securities, L.P.
(the foregoing transactions, collectively, shall be referred to herein as the
"Reorganization"). Prior to the effective date of the Registration Statement of
which this Prospectus is a part, certain non-management members of the LLC, who
have so elected, will receive a cash distribution of all or a portion of their
Undistributed Profits. Concurrently with such distribution, the LLC intends to
make a cash distribution to each member of an estimate of its share of the
total amount of profits of the LLC accruing between April 1, 1998 and the
closing of this Offering.
 
  Transactions with Affiliates. Immediately prior to the Reorganization, 60% of
the member interests of the LLC will be owned by a consortium of 27 broker-
dealers or their affiliates. Additionally, Brown & Company Securities
Corporation ("Brown"), a major customer of the Company, held subordinated debt
of the LLC and an option to purchase member interests in the LLC (the "Brown
Option"). After the closing of this Offering, such broker-dealer owners,
including Brown, will own 48.5% of the Company's Common Stock (47.2% if the
Underwriters' over-allotment option is exercised in full). For the period from
March 27, 1995 through December 31, 1995, the years ended December 31, 1996 and
1997, and the three months ended March 31, 1998, the broker-dealer owners and
subordinated note holders, were the source of 31.3%, 35.1%, 39.8%, and 41.3%,
respectively of the Company's total order flow. For the period from March 27,
1995 through December 31, 1995, the years ended December 31, 1996 and 1997, and
the three months ended March 31, 1998, aggregate payments by the Company to its
broker-dealer owners and subordinated note holders for order flow and aggregate
profit distributions to broker-dealer owners equaled $14.4 million and $1.7
million, $46.4 million and $10.6 million, $50.7 million and $13.4 million, and
$11.3 million and $5.0 million, respectively. See "Certain Transactions."
 
  Pursuant to the limited liability company agreement of the LLC, its broker-
dealer owners have partially shared in the LLC profits in proportion to their
equity interest and partially in proportion to the quantity of order flow they
have directed to the Company. This arrangement will be discontinued upon
consummation of the Reorganization. The broker-dealer owners will no longer
receive any special inducements to send order flow to the Company and will not
be contractually or otherwise obligated to provide the Company with any order
flow in the future. See "Risk Factors--Risks Associated with Change of
Ownership Structure."

                                 RISK FACTORS
 
  This Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements and from the results
historically experienced as a result of certain factors, including those in
the following risk factors and elsewhere in this Prospectus. In addition to
the other information contained in this Prospectus, the following risk factors
should be considered carefully in evaluating the Company and its business
before purchasing shares of the Class A Common Stock offered hereby.
 
RISKS ASSOCIATED WITH THE SECURITIES BUSINESS GENERALLY
 
  The securities industry has undergone several fundamental changes as a
result of new regulation at the federal and state level, the emergence of
electronic discount brokers, the increased prominence of institutional
investors, consolidation among firms in the securities industry and the
increased use of technology. These changes have resulted in an increase in the
volume of equity securities traded in the U.S. equity markets and a general
decrease in the spreads market makers receive. There can be no assurance that
the spreads market makers receive upon execution of trades in equity
securities will not continue to decrease in the future. A substantial portion
of the Company's revenues are derived from market-making activities relating
to securities that trade in NASDAQ. In the past, NASDAQ has taken regulatory
actions designed to reduce spreads between bid and ask prices for securities.
NASDAQ, NYSE and AMEX are currently examining proposed regulations pursuant to
which securities will trade in decimals rather than in fractions. The adoption
of such proposed regulations would likely result in a further decrease in
spreads between bid and ask prices, which could make the execution of trades
and market making less profitable. Any further decline in the spreads that
market makers receive in trading equity securities could have a material
adverse effect on the Company's business, financial condition and operating
results.
 
  The Company's volume of market-making activities also depends on the number
and size of new equity offerings and aftermarket trading for such securities.
The market for equity offerings has historically experienced significant
volatility not only in the number and size of equity offerings, but also in
the aftermarket trading volume and prices of newly issued securities. The
number and size of equity offerings may decline during periods of market
uncertainty occasioned by concerns over, among other things, inflation, rising
interest rates and related economic issues as well as a slowdown or reversal
of cash flows by mutual funds and other institutional investors into the U.S.
equity markets. The recent demand for new equity offerings has been driven in
part by mutual funds and other institutional investors. A decline in cash
flows into the U.S. equity markets or a slowdown in investment activity by
mutual funds and other institutional investors may have an adverse effect on
the securities markets generally and could result in lower revenues from the
Company's market-making activities. Any reduction in revenues resulting from a
decline in the number and size of new equity offerings or the aftermarket
trading volume of such offerings could have a material adverse effect on the
Company's business, financial condition and operating results.
 
  The securities business is also subject to various other risks, including
customer default, employees' misconduct, errors and omissions and litigation.
Losses associated with these risks could have a material adverse effect on the
Company's business, financial condition and operating results.
 
RISKS ASSOCIATED WITH CHANGE OF OWNERSHIP STRUCTURE
 
  The Company has historically derived a substantial portion of its order flow
from its broker-dealer owners. In the years ended December 31, 1996, 1997 and
the three months ended March 31, 1998, order flow from broker-dealer owners
and subordinated note holders represented 35.1%, 39.8% and 41.3%, of the
Company's total order flow, respectively. The Company's broker-dealer owners
have shared in profits partially in proportion to their equity interest and
partially in proportion to the quantity of order flow they have directed to
the Company. This arrangement will be discontinued upon consummation of the
Reorganization.
 
 
                                       7
<PAGE>
 
  The Company's broker-dealer owners are not contractually or otherwise
obligated to provide the Company with any order flow, and after the
Reorganization may no longer have sufficient inducement to do so. There can be
no assurance that the absence of such incentives will not cause the Company's
broker-dealer owners to reduce or discontinue the level of order flow they
direct to the Company in the future. The loss of, or a significant reduction
of, order flow from such broker-dealer owners could have a material adverse
effect on the Company's business, financial condition and operating results.
See "Certain Transactions--The Reorganization."
 
GOVERNMENT REGULATION
 
  The securities industry in the United States is subject to extensive
regulation under both federal and state laws. In addition, the U.S. Securities
and Exchange Commission (the "SEC"), the NASD, other self-regulatory
organizations ("SROs"), such as the various stock exchanges, and other
regulatory bodies, such as state securities commissions, require strict
compliance with their respective rules and regulations. As a matter of public
policy, regulatory bodies are charged with safeguarding the integrity of the
securities and other financial markets and with protecting the interests of
customers participating in those markets, not protecting creditors or
stockholders of market makers. Market makers are subject to regulation
concerning certain aspects of their business, including trade practices,
capital structure, record retention and the conduct of directors, officers and
employees. Failure to comply with any of these laws, rules or regulations
could result in censure, fines, the issuance of cease-and-desist orders or the
suspension or disqualification of its directors, officers or employees, and
other adverse consequences, which could have a material adverse effect on the
Company's business, financial condition and operating results. The Company and
certain of its officers and other employees have, in the past, been subject to
claims arising from the violation of such laws, rules and regulations, which
resulted in the payment of fines and settlements. There can be no assurance
that the Company and/or its officers and other employees will not, in the
future, be subject to claims arising from the violation of such laws, rules
and regulations. An adverse ruling against the Company and/or its officers and
other employees, including censure or suspension, could result in the Company
and/or its officers and other employees being required to pay a substantial
fine or settlement, and could result in their suspension or expulsion, which
could have a material adverse effect on the Company's business, financial
condition and operating results.
 
  In connection with a three-year industry-wide investigation conducted by the
staff (the "Staff") of the SEC into the trading and supervisory activities of
many OTC market makers and certain of their individual supervisory and trading
personnel, in July, 1997, the Staff informed Kenneth Pasternak, President and
Chief Executive Officer of the Company, that he is a subject in their
investigation for certain of his activities as a trading room supervisor at
Troster Singer. All of the activities being investigated took place prior to
Mr. Pasternak joining the Company in 1995 and none of them relate to his
employment by the Company. Mr. Pasternak has also been orally informed by the
Staff that, as a result of its investigation, it currently intends to
recommend to the SEC that Mr. Pasternak be charged with failure to supervise
with respect to several transactions of other traders under his supervision at
Troster Singer and that Mr. Pasternak be suspended for six months, ordered to
cease and desist, and assessed a civil penalty of $50,000. In September, 1997,
Mr. Pasternak submitted a brief to the Staff arguing that these
recommendations would be inappropriate and unsupported by the facts. To date,
the Staff has not forwarded its recommendations to the SEC. The Company cannot
predict the outcome of the Staff's investigation, including whether the Staff
will determine to forward its recommendations to the SEC in their current or a
modified form or at all. If any such charges are brought, Mr. Pasternak
intends to vigorously defend himself against them. If Mr. Pasternak should be
suspended, the Company would seek to replace his services with other Company
personnel. However, the loss of Mr. Pasternak's services would have a material
adverse effect on the Company's business, financial condition and operating
results.
 
  The regulatory environment in which the Company operates is subject to
change. The Company's business, financial condition and operating results may
be adversely affected as a result of new or revised
 
                                       8
<PAGE>
 
legislation or regulations imposed by the SEC, other United States or foreign
governmental regulatory authorities or the NASD. The Company's business,
financial condition and operating results also may be adversely affected by
changes in the interpretation or enforcement of existing laws and rules by
these governmental authorities and the NASD.
 
  Additional regulation, changes in existing laws and rules, or changes in
interpretations or enforcement of existing laws and rules often directly
affect the method of operation and profitability of securities firms. The
Company cannot predict what effect any such changes might have. Furthermore,
the Company's business, financial condition and operating results may be
materially affected not only by regulations directly applicable to it, but
also by regulations of general application. For example, the volume of the
Company's market-making activities in a given period could be affected by,
among other things, existing and proposed tax legislation, antitrust policy
and other governmental regulations and policies (including the interest rate
policies of the Board of Governors of the Federal Reserve System (the "Federal
Reserve Board")) and changes in interpretation or enforcement of existing laws
and rules that affect the business and financial communities. The level of
trading and market-making activity can be affected not only by such
legislation or regulations of general applicability, but also by industry-
specific legislation or regulations.
 
  The Company's market-making activities involve securities traded in NASDAQ.
NASDAQ's operations have been the subject of extensive scrutiny in the media
and by government regulators, including the Antitrust Division of the United
States Department of Justice. This scrutiny has included allegations of
collusion among NASDAQ market makers. In fact, a large group of NASDAQ market
makers recently entered into a Stipulation and Order with the Department of
Justice in which they agreed not to engage in any collusive activities
relating to prices, quotes or spreads in NASDAQ-traded securities. In August
1996, the SEC adopted certain new rules and rule amendments, known as the
Order Handling Rules, which significantly altered the manner in which orders
related to both NASDAQ and listed securities are handled. The implementation
of these rules began in January 1997. The SEC has also issued for comment
certain proposed rules by the NASD which, if approved, would introduce a new
system for delivering and executing orders in NASDAQ. The proposed NASD rules,
if approved, along with other potential regulatory actions and improvements in
technology, could impact the manner in which business is currently conducted
in NASDAQ. These new rules, regulatory actions, and changes in market customs
and practices could have a material adverse effect on the Company's business,
financial condition and operating results.
 
  The Company's business, both directly and indirectly, relies on the Internet
and other electronic communications gateways. The Company intends to expand
use of such gateways. To date, the use of the Internet has been relatively
free from regulatory restraints. However, the SEC, certain SROs and certain
states are beginning to address the regulatory issues that may arise in
connection with the use of the Internet. Accordingly, new regulations or
interpretations may be adopted that constrain the Company's and its customers'
ability to transact business through the Internet or other electronic
communications gateways. Any additional regulation of the use of such gateways
could have a material adverse effect on the Company's business, financial
condition and operating results.
 
  In addition, the Company may in the future expand its business to other
countries. To expand its services internationally, the Company would have to
comply with regulatory controls of each specific country in which it conducts
business. The brokerage industry in many foreign countries is heavily
regulated. The varying compliance requirements of these different regulatory
jurisdictions and other factors may limit the Company's ability to expand
internationally. There can be no assurance that the Company will be successful
in obtaining the necessary regulatory approvals for any such expansion, or if
such approvals are obtained, that the Company will be able to continue to
comply with such regulations. The failure to obtain or comply with such
approvals could have a material adverse effect on the Company's business,
financial condition and operating results. See "Business--Government
Regulation."
 
DEPENDENCE ON MARKET-MAKING ACTIVITIES AND CLEARING BROKERS
 
  Substantially all of the Company's revenues are derived from market-making
activities. The Company expects its market-making activities to continue to
account for substantially all of its revenues for the
 
                                       9
<PAGE>
 
foreseeable future. Any factor adversely affecting market-making in general,
or the Company's market-making activities in particular, could adversely
affect the Company's business, financial condition and operating results. The
Company's future success will depend on continued growth in demand for its
market-making services and its ability to respond to regulatory and
technological changes, as well as customer demands. If demand for the
Company's market-making services fails to grow, grows more slowly than the
Company currently anticipates, or declines, the Company's business, financial
condition and operating results could be materially and adversely affected.
 
  As a market maker of OTC and listed stocks, the majority of the Company's
securities transactions are conducted as principal with broker-dealer
counterparties located in the United States. The Company clears its securities
transactions through affiliated and unaffiliated clearing brokers. See
"Certain Transactions." Pursuant to the terms of the agreement between the
Company and the clearing brokers, the clearing brokers have the right to
charge the Company for losses that result from a counterparty's failure to
fulfill its contractual obligations. The Company's policy is to monitor the
credit standing of the counterparties with which it conducts business.
However, no assurance can be given that any such counterparty will not default
on their obligations, which default could have a material adverse effect on
the Company's business, financial condition and operating results. In
addition, at any time, a substantial portion of the Company's assets are held
at one or more clearing brokers and, accordingly, the Company is subject to
credit risk with respect to such clearing brokers. As of December 31, 1997 and
March 31, 1998, the Company's credit exposures were concentrated with the
clearing brokers and amounted to $30.2 million and $78.1 million,
respectively. Additionally, as of December 31, 1997 and March 31, 1998, the
clearing brokers held, as custodian, securities owned by the Company with a
market value of $61.7 million and $63.5 million, respectively. Consequently,
the Company is reliant on the ability of its clearing brokers to adequately
discharge their obligations on a timely basis. The Company is also dependent
on the solvency of such clearing brokers. Any failure by the clearing brokers
to adequately discharge their obligations on a timely basis, or failure by a
clearing broker to remain solvent, or any event adversely affecting the
clearing brokers, could have a material adverse effect on the Company's
business, financial condition and operating results.
 
RISK OF LOSSES ASSOCIATED WITH MARKET MAKING AND TRADING
 
  The Company conducts its market-making activities predominantly as a
principal, which subjects the Company's capital to significant risks. These
activities involve the purchase, sale or short sale of securities for the
Company's own account and, accordingly, involve risks of price fluctuations
and illiquidity, or rapid changes in the liquidity of markets that may limit
or restrict the Company's ability to either resell securities it purchases or
to repurchase securities it sells in such transactions. From time to time, the
Company has large position concentrations in securities of a single issuer or
issuers engaged in a specific industry, which might result in higher trading
losses than would occur if the Company's positions and activities were less
concentrated.
 
  The success of the Company's market-making activities depends upon its
ability to attract order flow, the skill of its personnel, general market
conditions, the price volatility of specific securities and the availability
of capital. To attract order flow, the Company must be competitive on price,
size of securities positions traded, order execution, technology and customer
service. In its role as a market maker, the Company attempts to derive a
profit from the difference between the prices at which it buys and sells
securities. However, competitive forces often require the Company to match the
quotes other market makers display and to hold varying amounts of securities
in inventory. By having to maintain inventory positions, the Company is
subjected to a high degree of risk. There can be no assurance that the Company
will be able to manage such risk successfully or that it will not experience
significant losses from such activities, either of which could materially
adversely effect the Company's business, financial condition and operating
results.
 
ABILITY TO ATTRACT AND RETAIN KEY PERSONNEL
 
  The Company's future success depends, in significant part, upon the
continued service of key executive officers, managers, sales, trading and
technical personnel, particularly Kenneth D. Pasternak, the Company's
 
                                      10
<PAGE>
 
President and Chief Executive Officer. The Company has entered into employment
agreements with Mr. Pasternak and other key employees and maintains "key
person" life insurance policies on Mr. Pasternak and other key employees for
the benefit of the Company. Competition for key personnel and other highly
qualified management, sales, trading and technical personnel is intense, and
there can be no assurance that the Company will be able to retain its key
personnel or that it can attract, assimilate or retain other highly qualified
personnel in the future. The loss of the services of any of the Company's key
personnel or the inability to identify, hire, train and retain other qualified
personnel in the future could have a material adverse effect on the Company's
business, financial condition and operating results. See "Risk Factors--
Government Regulation," "Management--Employment Agreements."
 
  The success of the Company also depends, in significant part, on the highly
skilled, and often specialized, individuals it employs. The Company's ability
to attract and retain management, sales, trading and technical professionals
is particularly important to its business strategy. The Company strives to
provide high quality services that will allow it to establish and maintain
long-term relationships with its customers. The Company's ability to do so
depends, in large part, upon the individual employees who represent the
Company in its dealings with such customers.
 
  From time to time, other companies in the securities industry have
experienced losses of sales and trading professionals. The level of
competition to attract such professionals is intense. There can be no
assurance that the Company will not lose such professionals due to increased
competition or other factors in the future. The loss of a sales and trading
professional, particularly a senior professional with broad industry
expertise, could have a material adverse affect on the Company's business,
financial condition and operating results.
 
  The Company expects that the number of its personnel will continue to grow,
particularly if current equity market activity continues and grows.
Competition for employees with the qualifications the Company desires is
intense, especially competition for equity trading professionals. There can be
no assurance that the Company will be able to recruit and retain a sufficient
number of new employees with the qualifications it desires in a timely manner
or that personnel costs will not increase significantly. The failure to retain
personnel or a significant increase in personnel costs could have a material
adverse effect on the Company's business, financial condition and operating
results.
 
RISKS ASSOCIATED WITH POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS; SEASONALITY
 
  The Company's operating results may fluctuate significantly in the future
due to a number of factors, including the value of the Company's securities
positions and the Company's ability to manage the risks attendant thereto, the
volume of its market-making activities, volatility in the securities markets,
its ability to manage personnel, overhead and other expenses, the amount of
revenue derived from limit orders as a percentage of total revenues, changes
in payments for order flow, clearing costs, the addition or loss of sales and
trading professionals, regulatory changes, the amount and timing of capital
expenditures, the incurrence of costs associated with acquisitions and general
economic conditions. The Company's expense structure is based on historical
expense levels and the levels of demand for the Company's market-making
services. If demand for the Company's market-making services declines and the
Company is unable to adjust its cost structure on a timely basis, the
Company's operating results could be materially and adversely affected. The
Company has experienced, and may experience in the future, significant
seasonality in its business. The Company has historically experienced an
increase in revenues in the fourth quarter of the year, which the Company
believes is due, in large part, to higher trading volumes in the securities
markets at year end. The Company believes that this seasonal trend will
continue for the foreseeable future and that the Company's business, financial
condition and operating results may be affected by such trends in the future.
 
  Due to all of the foregoing factors, period-to-period comparisons of the
revenues and operating results of the Company are not necessarily meaningful
and such comparisons cannot be relied upon as indicators of future
performance. There also can be no assurance that the Company will be able to
sustain the rates of revenue growth that it has experienced in the past, that
it will be able to improve its operating results or that
 
                                      11
<PAGE>
 
it will be able to sustain its profitability on a quarterly basis. In
addition, the Company's operating results in future periods may be below the
expectations of securities analysts and investors. In that event, the market
price of the Common Stock would likely be materially and adversely affected.
See "Management's Discussion and Analysis of Financial Condition and Results
of Operations."
 
RISKS ASSOCIATED WITH ADVERSE ECONOMIC, POLITICAL AND MARKET CONDITIONS
 
  The securities business generally is, by its nature, volatile. It is
directly affected by numerous national and international factors that are
beyond the Company's control, including, among others, economic, political and
market conditions; the availability of short-term and long-term funding and
capital; the level and volatility of interest rates; legislative and
regulatory changes; currency values and inflation. Any one or more of these
factors may contribute to reduced levels of activity in the securities markets
generally, which could result in lower revenues from the Company's market-
making activities. Any reduction in revenues or any loss resulting from such
factors could have a material adverse effect on the Company's business,
financial condition and operating results.
 
RISKS ASSOCIATED WITH DECLINES IN MARKET VOLUME, PRICE OR LIQUIDITY
 
  The Company's revenues may decrease in the event of a decline in market
volume, prices or liquidity. Declines in the volume of securities transactions
and in market liquidity generally result in lower revenues from market-making
activities. Lower price levels of securities may also result in reduced
trading volume, and could cause a reduction in trading activity, and thereby
reduce revenues from market-making transactions, as well as losses from
declines in the market value of securities held in inventory. Sudden sharp
declines in market values of securities can result in illiquid markets,
declines in the market values of securities held in inventory, the failure of
buyers and sellers of securities to fulfill their obligations and settle their
trades and increases in claims and litigation. Any decline in market volume,
price or liquidity or any other of these factors could have a material adverse
effect on the Company's business, financial condition and operating results.
 
RISKS ASSOCIATED WITH MANAGEMENT OF GROWTH
 
  Since its inception in 1995, the Company has experienced significant growth
in its business activities and the number of its employees. For example, the
Company's share volume has increased from 2.0 billion shares traded for the
quarter ended December 31, 1995 to 7.4 billion shares traded for the quarter
ended March 31, 1998 and the number of the Company's employees has increased
from 152 as of December 31, 1995 to 337 as of March 31, 1998. The growth of
the Company's business and expansion of its customer base has placed, and is
expected to continue to place, a significant strain on the Company's
management and operations. This growth has required and will continue to
require increased investment in management personnel, financial and management
systems and controls and facilities, which, in the absence of continued
revenue growth, would cause the Company's operating margins to decline from
current levels. In addition, as is common in the securities industry, the
Company is and will continue to be highly dependent on the effective and
reliable operation of its communications and information systems. The Company
believes that its current and anticipated future growth will require
implementation of new and enhanced communications and information systems, and
training of its personnel to operate such systems. In addition, the scope of
procedures for assuring compliance with applicable rules and regulations has
changed as the size and complexity of the Company's business has increased.
The Company has implemented and continues to implement formal compliance
procedures to reflect such growth. Accordingly, the Company's future operating
results will depend on its ability to continue to improve its systems for
operations, financial control, and communication and information management;
to enhance its compliance procedures; and to recruit, train, manage and retain
its employee base. There can be no assurance that the Company will be able to
manage or continue to manage its recent or any future growth successfully. The
Company's inability to do so could materially and adversely affect the
Company's business, financial condition and operating results. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
 
                                      12
<PAGE>
 
RISK RELATED TO CUSTOMER CONCENTRATION
 
  A small number of customers have historically accounted for a significant
portion of the Company's market-making activities, and the Company expects a
significant portion of the future demand for its market-making services to
remain concentrated within a limited number of customers. The Company's five
largest customers accounted for 22.3%, 29.4% and 33.8% of the Company's order
flow for the years ended December 31, 1996 and 1997, and the three months
ended March 31, 1998, respectively. None of these customers are contractually
obligated to utilize the Company as market maker and, accordingly, these
customers may direct their trading activities to other market makers at any
time. There can be no assurance that the Company will be able to retain these
or other major customers or that such customers will maintain or increase
their demand for the Company's market-making activities. The loss of, or a
significant reduction of demand for the Company's services from, any of these
customers could have a material adverse effect on the Company's business,
financial condition and operating results. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business--
Customers."
 
RISKS ASSOCIATED WITH LIMITED OPERATING HISTORY
 
  The Company began its operations in 1995 with the formation of Knight and
the acquisition of the listed securities market-making business of Trimark.
Knight, which has historically accounted for a substantial portion of the
Company's revenues, and is expected to continue to do so in the foreseeable
future, only began its operation in 1995. The Company's management has limited
experience with respect to the operations of Knight and in operating the
Company on a consolidated basis. Accordingly, the Company has a limited
consolidated operating history upon which an evaluation of the performance of
the Company and its prospects can be based. The Company's prospects must be
considered in light of the risks, uncertainties, expenses and difficulties
frequently encountered by similarly situated companies, particularly companies
in the securities industry that are subject to evolving regulatory,
technological and customer requirements. To address these risks, the Company
must, among other things, maintain existing customer relationships and
effectively develop new relationships, respond to regulatory and competitive
developments, attract, retain and motivate qualified personnel, and develop
and upgrade its technology. There can be no assurance that the Company will be
successful in addressing such requirements. The failure to do so could have a
material adverse effect on the Company's business, financial condition and
operating results.
 
RISKS ASSOCIATED WITH INTELLECTUAL PROPERTY RIGHTS
 
  The Company relies primarily on copyright, trade secret and trademark law to
protect its proprietary technology. Notwithstanding the precautions taken by
the Company to protect its intellectual property rights, it is possible that
third parties may copy or otherwise obtain and use the Company's proprietary
technology without authorization or otherwise infringe on the Company's
proprietary rights. It is also possible that third parties may independently
develop technologies similar to those of the Company. It may be difficult for
the Company to police unauthorized use of its proprietary technology and
intellectual property rights. There can be no assurance that the steps taken
by the Company will prevent misappropriation of its technology or intellectual
property rights.
 
  The Company is heavily dependent on two order entry and execution software
systems known as the "Brass System," which it licenses from Automated
Securities Clearance, Ltd. ("ASC") and the "Appletree System," which it
licenses from TCAM Systems, Inc. ("TCAM") pursuant to license agreements.
Although the Company has rights to modify the licensed software under the
license agreements, the licensors own all modifications and enhancements to
the licensed software, and the licensors can use the modifications and
enhancements to the licensed software without the Company's consent. While the
Company does not believe that ASC or TCAM has incorporated any such
modifications in software licensed to third parties, there can be no assurance
that they will not do so in the future or that any such license will not have
a material adverse effect on the Company's competitive position. The Company
relies on ASC to monitor the daily operation of the Brass System in order to
detect problems with the Brass System's operation. The Company relies on the
 
                                      13
<PAGE>
 
licensors to support and maintain the Brass and Appletree Systems. The
licenses, and the licensors' daily operation and support obligations are
terminable if the Company breaches its obligations under the license
agreements. The failure by the Company to maintain these relationships, or to
find a replacement for such technology in a timely and cost-effective manner,
could have a material adverse effect on the Company's business, financial
condition and operating results.
 
  The Company also licenses other software from third parties, which software
is integral to the Company's business. If any of these relationships were
terminated or if any of these third parties were to cease doing business, the
Company would be forced to spend significant time to replace the licensed
software, if possible. However, there can be no assurance that such
replacements would be available on reasonable terms, if at all. Such events
would have a material adverse effect upon the Company's business, financial
condition and operating results. In addition, litigation may be necessary in
the future to enforce the Company's intellectual property rights, to protect
the Company's trade secrets, to determine the validity and scope of the
proprietary rights of others, or to defend against claims of infringement or
invalidity. Such litigation, whether successful or unsuccessful, could result
in substantial costs and diversions of resources either of which could have a
material adverse effect on the Company's business, financial condition and
operating results. The Company may in the future receive notices of claims of
infringement of other parties' proprietary rights. There can be no assurance
that claims for infringement or invalidity (or claims for indemnification
resulting from infringement claims) will not be asserted or prosecuted against
the Company. Any such claims, with or without merit, could be time consuming
to defend, result in costly litigation, divert management's attention and
resources or require the Company to enter into royalty or licensing
agreements. There can be no assurance that such royalties or licenses would be
available on reasonable terms, if at all, and the assertion or prosecution of
any such claims, whether successful or unsuccessful, could have a material
adverse effect on the Company's business, financial condition and operating
results. See "Business--Intellectual Property and Other Proprietary Rights."
 
COMPETITION
 
  The Company derives substantially all of its revenues from market-making
activities. The market for these services, particularly market-making services
through electronic communications gateways, is rapidly evolving and intensely
competitive. The Company expects competition to continue and intensify in the
future. Knight competes primarily with wholesale, national, and regional
broker-dealers. Trimark competes with the NYSE, the AMEX, regional exchanges
and Third Market competitors. The Company competes primarily on the basis of
execution standards, its relationship with its customers and technology.
 
  A number of the Company's competitors have significantly greater financial,
technical, marketing and other resources than the Company. Some of the
Company's competitors also offer a wider range of services and products than
the Company and have greater name recognition and more extensive customer
bases than the Company. These competitors may be able to respond more quickly
to new or evolving opportunities, technologies and customer requirements than
the Company and may be able to undertake more extensive promotional activities
and offer more attractive terms to customers. Recent advancements in computing
and communications technology are substantially changing the means by which
market-making services are delivered, including more direct access on-line to
a wide variety of services and information, and have also created demand for
more sophisticated levels of customer service. The provision of such services
may entail considerable cost without an offsetting increase in revenues.
Moreover, current and potential competitors have established or may establish
cooperative relationships among themselves or with third parties or may
consolidate to enhance their services and products. New competitors or
alliances among competitors may emerge and they may acquire significant market
share.
 
  There can be no assurance that the Company will be able to compete
effectively with current or future competitors or that the competitive
pressures faced by the Company will not have a material adverse effect on the
Company's business, financial condition and operating results.
 
                                      14
<PAGE>
 
LITIGATION AND POTENTIAL SECURITIES LAWS LIABILITY
 
  Many aspects of the Company's business involve substantial risks of
liability. A market maker is exposed to substantial liability under federal
and state securities laws, other federal and state laws and court decisions,
as well as rules and regulations promulgated by the SEC and the NASD. The
Company is also subject to the risk of litigation and claims that may be
without merit. As the Company intends to defend actively any such litigation,
significant legal expenses could be incurred. An adverse resolution of any
future lawsuits or claims against the Company could have a material adverse
effect on the Company's business, financial condition and operating results.
 
RISKS ASSOCIATED WITH DEPENDENCE ON COMPUTER AND COMMUNICATIONS SYSTEMS
 
  The Company's market-making activities are heavily dependent on the
integrity and performance of the computer and communications systems
supporting them. Extraordinary trading volumes or other events could cause the
Company's computer systems to operate at an unacceptably low speed or even
fail. Any significant degradation or failure of the Company's computer systems
or any other systems in the trading process (e.g., on-line service providers,
record retention and data processing functions performed by third parties, and
third-party software, such as Internet browsers) could cause customers to
suffer delays in trading. Such delays could cause substantial losses for
customers and could subject the Company to claims from customers for losses,
including litigation claiming fraud or negligence. There can be no assurance
that the Company's network protections will work appropriately in the event of
a computer systems failure, or that, in the event of a tornado, fire or any
other natural disaster, power or telecommunications failure, act of God or
war, the Company will not suffer an extended computer systems failure. Any
computer or communications system failure or decrease in computer systems
performance that causes interruptions in the Company's operations could have a
material adverse effect on the Company's business, financial condition and
operating results. See "Business--Technology."
 
RISKS RELATED TO EVOLVING MARKETS; DEPENDENCE ON NEW SERVICES, PRODUCTS AND
TECHNOLOGIES
 
  The demand for market-making services, particularly services that rely on
electronic communications gateways is characterized by rapid technological
change, changing customer demands, the need to enhance existing or introduce
new services and products, and evolving industry standards. New services,
products and technologies may render the Company's existing services, products
and technologies less competitive. The Company's future success will depend,
in part, on its ability to respond to the demand for new services, products
and technologies on a timely and cost-effective basis and adapt to
technological advancements and changing standards to address the increasingly
sophisticated requirements of its customers. There can be no assurance that
the Company will be successful in the development, acquisition of adequate
rights to, introduction or marketing of such new services, products and
technologies. Any failure by the Company to anticipate or respond adequately
to technological advancements, customer requirements or changing industry
standards, or any significant delays in the development, introduction or
availability of new services, products or enhancements could have a material
adverse effect on the Company's business, financial condition and operating
results.
 
RISKS ASSOCIATED WITH UNCERTAINTY OF MARKET ACCEPTANCE OF NEW SERVICES,
PRODUCTS AND THE INTERNET
 
  The Company receives substantially all of its order flow through electronic
communications gateways, including a variety of computer-to-computer
interfaces and the Internet. The market for market-making services that rely
on the Internet is at an early stage of development and is rapidly evolving.
As a result, the demand for and market acceptance of recently introduced
services and products is subject to a high level of uncertainty. The Company's
electronic services may involve alternative approaches to market making and,
accordingly, substantial marketing and sales efforts may be necessary to
educate prospective customers regarding the use and benefit of the Company's
electronic services and products.
 
                                      15
<PAGE>
 
  The Company depends on the business it receives from broker-dealers who
increasingly rely on the Internet to conduct transactions with their
customers. The need for the Company's services and products depend on whether
the customers of such broker-dealers are willing to adopt the Internet as a
medium for commerce and communication. Customer concerns, including security,
reliability, cost, ease of use, accessibility and quality of service all may
negatively affect the growth of Internet use for such activities. The success
of the Internet will also depend on the development of necessary
infrastructure and complementary services and products, such as high speed
modems and high speed communication lines. As the number of users and the
amount of traffic on the Internet continues to increase, there can be no
assurance that the infrastructure needed to support the Internet will be able
to meet the demands placed on it. Finally, the success of the Internet will
also depend on government regulation and the ability of Internet users to
develop and adopt new standards and protocols to handle increased levels of
activity. As a result, there can be no assurance that the number of
transactions generated over the Internet will continue to increase. Any
reluctance of the clients of the Company's broker-dealer customers to obtain
brokerage services over the Internet may have a material adverse effect on the
Company's business, financial condition and operating results.
 
EFFECT OF NET CAPITAL REQUIREMENTS
 
  The SEC, the NASD and various other regulatory agencies have stringent rules
with respect to the maintenance of specific levels of net capital by
securities brokers, including the SEC's Uniform Net Capital Rule (the "Net
Capital Rule"), which governs the net capital requirements of each of the
Company's subsidiaries. Failure to maintain the required net capital may
subject a firm to suspension or revocation of registration by the SEC and
suspension or expulsion by the NASD and other regulatory bodies and ultimately
could require the firm's liquidation. In addition, a change in the net capital
rules, the imposition of new rules or any unusually large charge against net
capital could limit those operations of the Company that require the intensive
use of capital, and also could restrict the Company's ability to withdraw
capital from its brokerage subsidiaries, which in turn could limit the
Company's ability to pay cash dividends, repay debt and repurchase shares of
its outstanding stock. A significant operating loss or any unusually large
charge against net capital could adversely affect the ability of the Company
to expand or even maintain its present levels of business, which could have a
material adverse effect on the Company's business, financial condition and
operating results. See "Business--Government Regulation."
 
YEAR 2000
 
  Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. These date code fields
will need to accept four digit entries to distinguish 21st century dates from
20th century dates. As a result, in less than two years, computer systems
and/or software used by many companies, including computers involved in the
securities industry, may need to be upgraded to comply with such "Year 2000"
requirements. Significant uncertainty exists concerning the potential effects
associated with the failure to achieve such compliance. The Company has
undertaken a project to identify and modify non-year 2000 compliant
communications and data processing systems in anticipation of the Year 2000.
Although the Company's main trading-related systems are designed to be Year
2000 compliant, there can be no assurance that the Company's proprietary
software and systems or any other software or systems licensed by third
parties to the Company contain all necessary date code changes or that it will
not be adversely affected by the failure of other companies' software to be
Year 2000 compliant. The Company plans to have its other computer systems
certified by the end of 1998. However, there can be no assurance that such
schedule will be met or that any software or systems licensed by third parties
to the Company, on which the Company's business is dependent, will be
corrected in a timely manner or that any such failure by such third parties
would not disrupt the Company's ability to accurately communicate with its
customers or its customers' ability to utilize the Company's services. Any
such disruption or failure could have an adverse effect on the Company's
business, financial condition and operating results. There can be no assurance
that third parties will not commence litigation against the Company for any
such disruption or failure.

ANTI-TAKEOVER EFFECTS OF CERTAIN PROVISIONS OF DELAWARE LAW AND THE COMPANY'S
CHARTER
 
  The Company is organized under the laws of the State of Delaware. Certain
provisions of Delaware law may have the effect of delaying, deferring, or
preventing a change in control of the Company. In addition, certain provisions
of the Company's Certificate of Incorporation (the "Certificate") may be
deemed to have anti-takeover effects and may delay, defer or prevent a
takeover attempt that a stockholder might consider in its best interest. The
Certificate will authorize the Board to determine the rights, preference,
privileges and restrictions of unissued series of preferred stock and to fix
the number of shares of any series of preferred stock and the designation of
any such series, without any vote or action by the Company's stockholders.
Thus, the Board can authorize and issue shares of preferred stock with voting
or conversion rights that could adversely affect the voting or other rights of
holders of the Company's Common Stock. In addition, the issuance of preferred
stock may have the effect of delaying, deferring, or preventing a change of
control of the Company, as the terms of the preferred stock that might be
issued could potentially prohibit the Company's consummation of any merger,
reorganization, sale of substantially all of its assets, liquidation or other
extraordinary corporate transaction without the approval of the holders of the
outstanding shares of the Common Stock.
 
SUBSTANTIAL DISCRETION IN USE OF PROCEEDS
 
  The company intends to use $13.8 million of the net proceeds from the
Offering to pay for the redemption of the Class B Preferred Units of the LLC.
The Company intends to use the balance of the net proceeds for working capital
and for general corporate purposes. Accordingly, management will have
significant flexibility in applying the net proceeds of the Offering. Although
the Company has no plans, commitments or agreements regarding any material
acquisitions as of the date of this Prospectus, the Company may seek
acquisitions of businesses, products or technologies that are complementary to
those of the Company, and a portion of the net proceeds may be used for such
acquisitions. See "Use of Proceeds."
 
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
  Prior to the Offering, there was no public market for the Company's Class A
Common Stock. The Company has applied to have the Class A Common Stock
approved for quotation in NASDAQ as a National Market issue under the symbol
"NITE." There can be no assurance that an active public market for the Class A
Common Stock will develop or be sustained. The initial public offering price
will be determined through negotiations between the Company and the
representatives of the Underwriters, and it may not be indicative of the
market price for the Class A Common Stock after the Offering is complete. The
market price of the Class A Common Stock after completion of the Offering
could be subject to significant fluctuations in response to quarterly
variations in operating results, announcements of new services or products by
the Company or its competitors, changes in financial estimates by securities
analysts or other vents or factors many of which are beyond the Company's
control. In addition, stock markets generally, and the stock prices of
competitors in the Company's industry specifically, experience significant
price and volume volatility from time to time which may adversely affect the
market price of the Class A Common Stock for reasons unrelated to the
Company's performance. There can be no assurance that purchasers of Class A
Common Stock will be able to resell their Class A Common Stock at prices equal
to or greater than the initial public offering price. See "Underwriting."
 
IMMEDIATE SUBSTANTIAL DILUTION
 
  Purchasers of Class A Common Stock in the Offering will experience an
immediate and substantial dilution of $12.29 in the net tangible book value
per share of their investment. If the Company issues additional Common Stock
in the future, purchasers of Class A Common Stock in the Offering may
experience further dilution in the net tangible book value of their Class A
Common Stock. See "Dilution." The Company does not anticipate paying any cash
dividends on its Common Stock in the foreseeable future. See "Dividend
Policy."

FUTURE CAPITAL NEEDS; UNCERTAINTY OF ADDITIONAL FINANCING
 
  The Company's business is dependent upon the availability of adequate
funding and regulatory capital under applicable regulatory requirements.
Historically, the Company has satisfied these needs from internally generated
funds. Prior to the Reorganization, the LLC will pay a portion of its
undistributed profits to its members, thereby reducing the Company funds
available for business operations. The Company currently anticipates, based on
management's experience and current industry trends, that its available cash
resources, combined with the net proceeds to the Company from the Offering,
will be sufficient to meet its presently anticipated working capital and
capital expenditure requirements for at least the next 12 months. The Company
expects that it will incur approximately $8.0 million in capital expenditures
in 1998. However, if the Company needs to raise additional funds to support
more rapid expansion, develop new or enhanced services and products, respond
to competitive pressures, acquire complementary businesses, products or
technologies or respond to unanticipated requirements, there can be no
assurance that additional financing will be available when needed on terms
favorable to the Company. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon consummation of the Offering, the Company will have 47,484,299 shares
of Class A Common Stock and 3,945,528 shares of Class B Common Stock
outstanding. Of these shares, the shares of Class A Common Stock offered
hereby will be freely tradeable without restriction or further registration
under the Securities Act, by persons other than affiliates of the Company
within the meaning of Rule 144 promulgated under the Securities Act. The
remaining shares, other than shares held by affiliates, may also be freely
tradeable. 41,429,827 of these shares are held by affiliates and, accordingly,
are "restricted securities" as that term is defined in Rule 144 under the
Securities Act and may be sold only if registered or pursuant to an exemption
from registration.
 
  In addition, the existing stockholders have the right to cause the Company
to register the sale of certain shares of Class A Common Stock or Class B
Common Stock owned by them and/or to include their shares in future
registrable statements relating to the Company's securities.
 
  Each of the Company, its directors and officers and certain other
stockholders has agreed that it will not offer, sell, contract to sell,
announce its intention to sell, pledge or otherwise dispose of, directly or
indirectly, or file with the SEC a registration statement under the Securities
Act relating to, any additional shares of the Class A Common Stock or
securities convertible into or exchangeable or exercisable for any shares of
the Class A Common Stock without the prior written consent of BancAmerica
Robertson Stephens for a period of 180 days after the date of this Prospectus.
See "Shares Eligible for Future Sale" and "Underwriting."
 
  After the date of this Prospectus, the Company intends to file a Form S-8
registration statement under the Securities Act to register all shares of
Common Stock issuable under the Company's stock option plan. Such registration
statement is expected to become effective immediately upon filing, and shares
covered by that registration statement will thereupon be eligible for sale in
the public markets, subject to certain lock-up agreements and Rule 144
limitations applicable to affiliates. See "Management," "Description of
Capital Stock--Registration Rights," "Shares Eligible for Future Sale" and
"Underwriting."

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 8,688,246 shares of
Class A Common Stock offered by the Company hereby are estimated to be
approximately $120.4 million ($141.4 million if the Underwriters' over-
allotment option is exercised in full) at an assumed initial public offering
price of $15.00 per share after deducting underwriting discounts and
commissions and estimated offering expenses payable by the Company. The
Company will not receive any proceeds from the sale of Class A Common Stock by
the Selling Stockholder. See "Principal and Selling Stockholders."
 
  The principal purposes of the Offering are to increase the Company's working
capital and equity base, to provide a public market for its Class A Common
Stock, to permit future acquisitions using cash or publicly tradeable Class A
Common Stock, and to facilitate future access to capital markets. From the
proceeds of the Offering, the Company intends to use $13.8 million to pay for
the redemption of all of the outstanding Preferred B Units of the LLC. The
Company intends to use the remaining proceeds of the Offering for working
capital and for general corporate purposes. The Company may also use a portion
of the proceeds of the Offering to pursue acquisitions of or investments in
businesses, products or technologies that are complementary to those of the
Company. The Company currently does not have any commitments or agreements
with respect to any such acquisitions. Pending such uses, the Company intends
to invest the net proceeds of the Offering in short-term, investment-grade,
interest-bearing securities.
 
                                DIVIDEND POLICY
 
  Prior to the Reorganization, the LLC has been treated as a partnership for
federal and state income tax purposes. Since inception, the LLC generated
taxable income and made distributions to its members to facilitate the payment
of the tax liability associated with the allocation of LLC income of an
aggregate of $2.9 million, $17.6 million, $22.3 million and $8.4 million in
1995, 1996, 1997, and the three months ended March 31, 1998, respectively. In
addition, prior to the Reorganization, the LLC will distribute to its members
all of its Undistributed Profits (other than $26.1 million which certain LLC
members have elected not to have distributed and to receive in exchange
therefor additional shares of Common Stock), as well as all of its taxable
income earned during the period beginning April 1, 1998 and ending with the
closing of the Offering. See "Certain Transactions--The Reorganization."
 
  The Company intends to retain future earnings, if any, to finance the
development and expansion of its business and, therefore, does not anticipate
paying any cash dividends on its Common Stock in the foreseeable future. The
payment of cash dividends is within the discretion of the Company's Board of
Directors and will be dependent upon, among other factors, the Company's
results of operations, financial condition and capital requirements,
restrictions imposed by the Company's financing arrangements and legal
requirements.

public offering price of $15.00 per share and the application of the estimated
net proceeds therefrom and the exercise of the Brown Option. See "Use of

                                   DILUTION
 
  The pro forma net tangible book value of the Company as of March 31, 1998,
giving effect to the Reorganization, Option Exercise and the Redemption, was
$19.1 million or $0.45 per share. Pro forma net tangible book value per share
represents the amount of total tangible assets less total liabilities, divided
by the number of shares of Common Stock outstanding. After giving effect to
the sale of 8,688,246 shares of Class A Common Stock offered by the Company
hereby (at an assumed initial public offering price of $15.00 per share and
after deducting underwriting discounts and commissions and estimated offering
expenses), the pro forma as adjusted net tangible book value of the Company as
of March 31, 1998 would have been approximately $139.5 million or $2.71 per
share. This represents an immediate dilution of $12.29 per share to new
investors in this Offering. The following table illustrates this per share
dilution:

(1) Sales by the Selling Stockholder in this offering will cause the number of
    shares held by existing stockholders to be reduced to 41,429,827 shares or
    80.6% (41,429,827 shares or 78.3% if the Underwriters' over-allotment
    option is exercised in full) of the total number of shares of Common Stock
    to be outstanding after this Offering, and will increase the number of
    shares held by new investors to 10,000,000 shares or 19.4% (11,500,000
    shares or 21.7% if the Underwriters' over-allotment option is exercised in
    full) of the total number of shares of Common Stock to be outstanding
    after this Offering. See "Principal and Selling Stockholders."
 
  The calculation of pro forma net tangible book value and the other
computations above assume no exercise of stock options outstanding, except for
the Option Exercise. As of the date of this Prospectus, there were options
outstanding to purchase a total of      shares of Class A Common Stock at an
exercise price equal to the initial public offering price. See
"Capitalization," "Management--Stock Option Plan," "Description of Capital

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
OVERVIEW
 
  The Company is a leading market maker in NASDAQ securities, other OTC equity
securities, and NYSE- and AMEX- listed equity securities in the Third Market.
Through its wholly-owned subsidiary, Knight, the Company makes markets in
approximately 4,200 equity securities in NASDAQ and on the NASD's OTC Bulletin
Board. Through its wholly-owned subsidiary, Trimark, the Company makes markets
in all NYSE- and AMEX-listed equity securities in the Third Market.
 
  Knight commenced NASDAQ and OTC securities market making operations on July
24, 1995. Based on rankings published by AutEx, an electronic database and
online, real-time network for trade order indications used by the securities
industry, Knight was ranked first in AutEx's Nasdaq/OTC Securities rankings,
with a 8.95% and 9.93% market share, respectively, during February and March
1998. Knight's share volume totaled 1.1 billion, 5.7 billion and 11.2 billion,
or 23%, 53% and 62% of the Company's total share volume, during the period
from March 27, 1995 through December 31, 1995 and the years ended December 31,
1996 and 1997, respectively. For the three months ended March 31, 1998,
Knight's share volume grew 161% to 5.0 billion, or 67% of the Company's total
share volume, from 1.9 billion shares, or 56% of the Company's total share
volume, in the same period in 1997. Since commencing operations in 1995,
Knight's business has grown rapidly and accounted for 76%, 75% and 77% of the
Company's total share volume growth during the years ended December 31, 1996
and 1997, and the three months ended March 31, 1998, respectively.
 
  Trimark commenced operations on March 27, 1995 when it acquired the NYSE-
and AMEX-listed equity securities market-making business and certain assets of
Trimark Securities, Inc. for $15 million in Mandatorily Redeemable Preferred B
Units and additional consideration based on Trimark's earnings during the five
years immediately following the acquisition. On November 17, 1997, Trimark
purchased the business and certain of the assets of Tradetech Securities, L.P.
("Tradetech"), a direct competitor of Trimark, for $750,000 in cash and
additional consideration based on Trimark's earnings during a minimum of three
years immediately following the acquisition. Since March, 1995, Trimark has
experienced significant increases in share volumes. Trimark's share volume
totaled 3.7 billion, 5.1 billion and 6.9 billion, or 77%, 47% and 38% of the
Company's total share volume during the period from March 27, 1995 through
December 31, 1995 and the years ended December 31, 1996 and 1997,
respectively. With the acquisition of Tradetech, Trimark's share volume grew
63% for the three months ended March 31, 1998 to 2.4 billion shares, from 1.5
billion shares for the comparable period in 1997 and accounted for 33% of the
Company's share volume for the three months ended March 31, 1998.
 
  The Company was organized in April 1998 for the purpose of succeeding to the
business of the LLC. Concurrent with the closing of the Offering, based on an
assumed initial public offering price of $15.00 per share, all of the member
interests of the LLC will be exchanged for 41,000,000 shares of Common Stock
of the Company. Certain members, who have so elected, will receive additional
shares of Class A Common Stock valued at the initial public offering price
with respect to their share of the Undistributed Profits. Management of the
Company has elected to receive shares of Class A Common Stock for all of its
Undistributed Profits. The Company will receive no additional consideration in
connection with such conversion of member interests into shares of Common
Stock. In connection with the exchange, Knight will become the successor
entity to Knight Securities, L.P., and Trimark will become the successor
entity to Trimark Securities, L.P. Prior to the effective date of the
Registration Statement of which this Prospectus is a part, certain members of
the LLC, who have so elected, will receive a cash distribution of all or a
portion of their Undistributed Profits. Concurrently with such distribution,
the LLC intends to make a cash distribution to each member of an estimate of
its share of the total amount of profits of the LLC accruing between April 1,
1998 and the closing of this Offering.
 
                                      23

  Immediately prior to the Reorganization, 60% of the member interests of the
LLC will be owned by a consortium of 27 broker-dealers or their affiliates.
Additionally, Brown & Company Securities Corporation ("Brown"), a major
customer of the Company, held subordinated debt of the LLC and an option to
purchase a member interest in the LLC (the "Brown Option"). After the closing
of this Offering, such broker-dealer owners, including Brown, will own 48.5%
of the Company's Common Stock (47.2% if the Underwriters' over-allotment
option is exercised in full). For the period from March 27, 1995 through
December 31, 1995, the years ended December 31, 1996 and 1997, and the three
months ended March 31, 1998, the broker-dealer owners and subordinated note
holders, were the source of 31.3%, 35.1%, 39.8%, and 41.3%, respectively of
the Company's total order flow. For the period from March 27, 1995 through
December 31, 1995, the years ended December 31, 1996 and 1997 and the three
months ended March 31, 1998, aggregate payments by the Company to its broker-
dealer owners and subordinated note holders for order flow and aggregate
profit distributions to broker-dealer owners equaled $14.4 million and $1.7
million, $46.4 million and $10.6 million, $50.7 million and $13.4 million,
$11.3 million and $5.0 million, respectively. See "Certain Transactions."
 
  Pursuant to the limited liability company agreement of the LLC, its broker-
dealer owners have partially shared in the LLC profits in proportion to their
equity interest and partially in proportion to the quantity of order flow they
have directed to the Company. This arrangement will be discontinued upon
consummation of the Reorganization. The broker-dealer owners will no longer
receive any special inducements to send order flow to the Company and will not
be contractually or otherwise obligated to provide the Company with any order
flow in the future. See "Risk Factors--Risks Associated with Change of
Ownership Structure."
 
 Revenues
 
  The Company's revenues consist principally of net trading revenue from
market-making activities and, to a much lesser extent, net interest income
from the Company's cash and securities positions held at banks and in trading
accounts at clearing brokers. To date, the Company has only traded equity
securities, and has never traded in options, futures, forwards, swaps or other
derivative instruments. Net trading revenue, which represents trading gains
net of trading losses, is primarily affected by changes in trade and share
volumes from customers, the Company's ability to derive trading gains by
taking proprietary positions to facilitate customer transactions and, most
recently, by regulatory changes, and evolving industry customs and practices.
These regulatory changes and the move from securities being quoted in
sixteenths rather than eighths of a dollar have resulted in a decrease in net
trading revenue per trade. The Company's net trading revenue per trade for OTC
securities has historically exceeded the net revenue per trade for listed
securities.
 
  Interest, net includes interest earned on cash balances held at banks and
clearing brokers, net of transaction-related interest charged by clearing
brokers for facilitating the settlement and financing of securities sold, not
yet purchased, and interest on subordinated notes. Interest, net is primarily
affected by the changes in cash balances held at banks and clearing brokers,
and the level of securities sold, not yet purchased, and the principal amount
outstanding under the subordinated notes.
 
 Expenses
 
  The Company's operating expenses largely consist of payments for order flow,
execution and clearance fees and employee compensation and benefits. A
substantial portion of these expenses are variable in nature. Payments for
order flow fluctuate based on share volume, the mix of market orders and limit
orders and the mix of orders received from broker-dealers compared to other
institutional customers. Execution and clearance fees fluctuate primarily
based on changes in trade and share volume, the mix of trades of OTC
securities compared to listed securities and the clearance fees charged by
clearing brokers. Employee compensation and benefits expense, which is largely
profitability based, fluctuates, for the most part, based on changes in net
trading revenue and the Company's profitability.
 
                                      24
<PAGE>
 
  Payments for order flow represent customary payments to broker-dealers, in
the normal course of business, for directing their order flow to the Company.
The Company does not pay for order flow from non-broker-dealer customers. As a
result of the new Order Handling Rules implemented by the SEC in 1997, the
Company changed its order flow payment policy from paying broker-dealers for
substantially all order executions, to paying broker-dealers only for orders
which provide the Company with a profit opportunity. For example, the Company
makes payments on market orders, but does not pay on limit orders. As a result
of these changes, the average order flow payment per transaction has declined.
 
  Execution and clearance fees primarily represent clearance fees paid to
clearing brokers for OTC and listed securities, transaction fees paid to
NASDAQ for OTC securities, and execution fees paid to third parties, primarily
for executing trades in listed securities on the NYSE and AMEX and for
executing orders through Electronic Communications Networks ("ECNs").
Execution and clearance fees are higher for listed securities than for OTC
securities. Due to the Company's significant growth in share and trade volume,
the Company has been able to negotiate favorable rates and volume discounts
from clearing brokers and providers of execution services. As a result of
these lower rates and discounts and the increase in trade volume of OTC
securities as a percentage of total trade volume, execution and clearance fees
per trade have decreased.
 
  Employee compensation and benefits expense primarily consists of salaries
and wages paid to administrative and customer service personnel and
profitability based compensation, which includes compensation and benefits
paid to market-making and sales personnel based on their individual
performance, and incentive compensation paid to all other employees based on
the overall profitability of the Company ("Profitability Based Compensation").
Profitability Based Compensation represented 65%, 79% and 78% of total
employee compensation and benefits expense for the period from March 27, 1995
through December 31, 1995 and the years ended December 31, 1996 and 1997,
respectively. Profitability Based Compensation represented 78% and 72% of
employee compensation and benefits expense for the three months ended March
31, 1997 and 1998, respectively. The Company has grown from 152 employees at
December 31, 1995 to 195 employees, 317 employees and 337 employees as of
December 31, 1996, 1997 and March 31, 1998, respectively. More than 70% of the
Company's employees are directly involved in market-making, sales or customer
service activities.
 
  Communications and data processing expense primarily consists of costs for
obtaining stock market data and telecommunications services.
 
  Depreciation and amortization expense results from the depreciation of fixed
assets purchased by the Company or financed under a capital lease, and the
amortization of goodwill, which includes contingent consideration, resulting
from the acquisition of the listed securities market-making business of
Trimark and the Tradetech acquisition.
 
  Interest on Preferred Units expense represents required interest payments on
the Company's Mandatorily Redeemable Preferred A and B Units at a rate
approximating the Federal Funds rate. As of April 15, 1998, all outstanding
Preferred A Units have been redeemed and the Company has redeemed $1.2 million
of Preferred B Units. The Company intends to redeem all of the remaining
Preferred B Units for $13.8 million with the proceeds of this Offering.
 
  Occupancy and equipment rentals expense primarily consists of rental
payments on office and equipment leases.
 
  Business development expense primarily consists of marketing expenses,
including travel and entertainment expenses and promotion and advertising
costs.
 
  Other expenses primarily consist of fees paid to computer programming and
systems consultants, as well as legal fees and other professional fees.

 Income Tax
 
  Prior to the Reorganization, the Company was a limited liability company and
was not subject to federal or state income taxes. Subsequent to the
Reorganization, which will occur concurrently with the consummation of this
Offering, the Company will be subject to federal income taxes and state income
taxes in New York, New Jersey and other states. Income tax expense includes
pro forma amounts relating to federal income taxes, as well as pro forma
amounts relating to state income taxes in New York, New Jersey and other
states. The Company's pro forma effective tax rate will generally differ from
the federal statutory rate of 35% primarily due to state income taxes, as well
as the effect of nondeductible expenses, including the amortization of
goodwill resulting from the acquisition of the listed securities market-making
business of Trimark and the Tradetech acquisition and a portion of business
development expenses.

THREE MONTHS ENDED MARCH 31, 1998 AND 1997
 
 Revenues
 
  Net trading revenue increased 24.8% to $63.0 million for the three months
ended March 31, 1998, from $50.5 million for the comparable period in 1997.
This increase was primarily due to higher trading volume, particularly higher
trade volume for OTC securities, which was offset in part by lower average net
trading revenue per trade. Total trade volume increased 100.3% to 7.6 million
trades for the three months ended March 31, 1998, from 3.8 million trades for
the comparable period in 1997. Total share volume increased 118.3% to 7.4
billion shares traded for the three months ended March 31, 1998, from 3.4
billion shares traded for the comparable period in 1997. Average net trading
revenue per trade decreased 37.7% to $8.32 per trade for the three months
ended March 31, 1998, from $13.36 per trade for the comparable period in 1997.
The
 
                                      26
<PAGE>
 
decrease in average net trading revenue per trade was primarily due to the new
Order Handling Rules, which were implemented between January 1997 and October
1997, and, to a lesser extent, the move to securities being quoted in
sixteenths of a dollar rather than eighths of a dollar.
 
  Interest, net increased 6.1% to $526,000 for the three months ended March
31, 1998, from $496,000 for the comparable period in 1997. This increase was
primarily due to larger cash balances held at banks and the Company's clearing
brokers, which was offset, in part, by increased transaction-related interest
expense resulting from a higher level of securities sold, not yet purchased.
 
 Expenses
 
  Payments for order flow decreased 10.3% to $16.3 million for the three
months ended March 31, 1998, from $18.1 million for the comparable period in
1997. As a percentage of net trading revenue, payments for order flow
decreased to 25.8% for the three months ended March 31, 1998, from 35.9% for
the comparable period in 1997. The decrease in payments for order flow on a
dollar basis and as a percentage of total revenue resulted from changes in the
Company's order flow payment policy, changes in the mix of market orders
versus limit orders, and changes in customer mix. Payments for order flow made
to broker-dealer owners and subordinated note holders represented 69.6% of
total payments for order flow for the three months ended March 31, 1998, as
compared to 78.9% for the comparable period in 1997 due to the expansion of
the Company's broker-dealer customer base.
 
  Execution and clearance fees increased 59.7% to $10.2 million for the three
months ended March 31, 1998, from $6.4 million for the comparable period in
1997. As a percentage of net trading revenue, execution and clearance fees
increased to 16.3% of net trading revenue for the three months ended March 31,
1998, from 12.7% of net trading revenue for the comparable period in 1997. The
increase on a dollar basis was primarily due to a 100.3% increase in trades
for the comparable period in 1997, which was offset, in part, by a decrease in
clearance rates charged by clearing brokers and higher growth in the volume of
OTC securities transactions, which have lower execution costs than
transactions in listed securities. The increase in execution and clearance
fees as a percentage of net trading revenue was primarily due to the decrease
in the average net trading revenue per trade.
 
  Employee compensation and benefits expense increased 34.6% to $16.2 million
for the three months ended March 31, 1998, from $12.0 million for the
comparable period in 1997. As a percentage of net trading revenue, employee
compensation increased to 25.7% of net trading revenue for the three months
ended March 31, 1998, from 23.8% of net trading revenue for the comparable
period in 1997. The increase on a dollar basis and as a percentage of net
trading revenue was primarily due to the Company's increased profitability and
an increase in the number of employees. Due to increased net trading revenue
and profitability, Profitability Based Compensation increased 24.8% to $11.6
million for the three months ended March 31, 1998, from $9.3 million for the
comparable period in 1997. The number of employees increased to 337 employees
as of March 31, 1998, from 228 employees as of March 31, 1997.
 
  Communications and data processing expense increased 64.5% to $2.2 million
for the three months ended March 31, 1998, from $1.3 million for the
comparable period in 1997. This increase was generally attributable to higher
trading volumes, and an increase in the number of employees.
 
  Depreciation and amortization expense increased 37.9% to $1.3 million for
the three months ended March 31, 1998, from $936,000 for the comparable period
in 1997. This increase was primarily due to the purchase of additional fixed
assets and leasehold improvements during 1997 and the first quarter of 1998 to
support the Company's expanded operations, and, to a lesser extent, the
amortization of goodwill recognized as part of the Tradetech acquisition,
which was completed in November 1997.
 
  Interest on Preferred Units expense decreased 31.0% to $416,000 for the
three months ended March 31, 1998, from $604,000 for the comparable period in
1997. This decrease was primarily due to the redemption and retirement of
$10.2 million Preferred A Units by the Company in April 1997.
 
                                      27
<PAGE>
 
  Occupancy and equipment rental expense increased 101.5% to $1.1 million for
the three months ended March 31, 1998, from $537,000 for the comparable period
in 1997. This increase was primarily attributable to additional office space
and increased computer equipment lease expense. The Company occupied 75,768
square feet of office space at March 31, 1998, up from 47,598 square feet of
office space at March 31, 1997.
 
  Business development expense increased 54.2% to $377,000 for the three
months ended March 31, 1998, from $244,000 for the comparable period in 1997.
This increase was primarily the result of higher travel and entertainment
costs.
 
  Other expenses increased 104.6% to $747,000 for the three months ended March
31, 1998, from $365,000 for the comparable period in 1997. This was the result
of increased fees for computer programming and systems consultants.
 
 Income Tax
 
  Pro forma income tax expense was determined using an effective tax rate of
43% for the three months ended March 31, 1998 and 1997.
 
YEAR ENDED DECEMBER 31, 1997 AND 1996
 
 Revenues
 
  Net trading revenue increased 22.2% to $224.6 million in 1997, from $183.9
million in 1996. This increase was primarily due to higher trading volume,
particularly higher trade volume for OTC securities, which was offset in part
by lower average net revenue per trade. Total trade volume increased 74.7% to
20.3 million trades in 1997, from 11.6 million trades in 1996. Total share
volume increased 68.5% to 18.1 billion shares traded in 1997, from 10.8
billion shares traded in 1996. Average net revenue per trade decreased 30.1%
to $11.09 per trade in 1997, from $15.86 per trade in 1996, principally as a
result of the new Order Handling Rules, which were implemented during 1997,
and the reduction in the increments by which securities are quoted.
 
  Interest, net increased 59.0% to $2.0 million in 1997, from $1.3 million in
1996. This increase was primarily due to larger cash balances held at banks
and the Company's clearing brokers, which was offset in part by increased
transaction-related interest expense resulting from a higher level of
securities sold, not yet purchased.
 
 Expenses
 
  Payments for order flow decreased 4.2% to $66.9 million, from $69.8 million
in 1996. As a percentage of net trading revenue, payments for order flow
decreased to 29.8% in 1997, as compared to 38.0% in 1996. The decrease in
payments for order flow on a dollar basis and as a percentage of total revenue
resulted from changes in the Company's order flow payment policy, changes in
the mix of market orders versus limit orders, and changes in customer mix.
Payments for order flow made to broker-dealer owners and subordinated note
holders represented 75.7% of total payments for order flow in 1997, from 66.4%
in 1996.
 
  Execution and clearance fees increased 24.1% to $32.1 million in 1997, from
$25.8 million in 1996. As a percentage of net trading revenue, execution and
clearance fees remained relatively constant and were 14.3% of net trading
revenue in 1997 and 14.0% of net trading revenue in 1996. The increase on a
dollar basis was primarily due to increased trade volume, which was offset, in
part, by a decrease in clearance rates charged by clearing brokers, and growth
in the volume of OTC securities transactions, which have lower execution costs
than transactions in listed securities. The increase in execution and
clearance fees as a percentage of net trading revenue was primarily due to the
decrease in the average net trading revenue per trade.
 
  Employee compensation and benefits expense increased 46.1% to $57.7 million
in 1997, from $39.5 million in 1996. As a percentage of net trading revenue,
employee compensation and benefits expense increased to 25.7% in 1997, from
21.5% in 1996. The increase on a dollar basis and as a percentage of net
trading revenue was primarily due to the Company's increased profitability and
growth in the number of employees. Due to increased net trading revenue and
profitability, Profitability Based Compensation increased 44.2% to $45.0
million in 1997, from $31.2 million in 1996. The number of employees increased
to 317 employees as of December 31, 1997, from 195 employees as of December
31, 1996.

  Communications and data processing expense increased 56.2% to $6.8 million
in 1997, from $4.4 million in 1996. This increase was generally attributable
to higher trading volumes, and an increase in the number of employees.
 
  Depreciation and amortization expense increased 42.0% to $4.2 million in
1997, from $3.0 million in 1996. This increase was primarily due to the
purchase of approximately $4.8 million of additional fixed assets and
leasehold improvements during 1997 and the amortization of goodwill related to
the acquisition of the listed securities market-making business of Trimark.
 
  Interest on Preferred Units expense decreased 7.2% to $1.9 million in 1997,
from $2.1 million in 1996. This decrease was primarily due to the redemption
and retirement of 1,022,208 Preferred A Units by the Company in April 1997 for
$10.2 million.
 
  Occupancy and equipment rentals expense increased 49.6% to $2.7 million in
1997, from $1.8 million in 1996. This increase was primarily attributable to
additional office space and increased computer equipment lease expense. The
Company occupied 56,351 square feet of office space at December 31, 1997, up
from 47,598 square feet of office space at December 31, 1996.
 
  Business development expense increased 134.1% to $1.5 million in 1997, from
$623,000 in 1996. This increase was primarily the result of higher travel and
entertainment costs.
 
  Other expenses increased 96.0% to $2.8 million in 1997, from $1.4 million in
1996. This increase was primarily due to increased professional fees for
computer programming and systems consultants.
 
 Income Tax
 
  Pro forma income tax expense was determined using an effective tax rate of
43% for 1997 and 1996.
 
YEAR ENDED DECEMBER 31, 1996 VERSUS THE PERIOD FROM MARCH 27, 1995 THROUGH
 DECEMBER 31, 1995
 
 Revenues
 
  Net trading revenue increased to $183.9 million in 1996, from $69.5 million
for the period from March 27, 1995 through December 31, 1995 (the "1995
Period"). Total trade volume increased to 11.6 million trades in 1996, from
5.0 million trades in the 1995 Period. Total share volume increased to 10.8
billion shares traded in 1996, from 4.7 billion shares traded in the 1995
Period. Average net trading revenue per trade increased to $15.86 per trade in
1996, from $13.92 per trade in the 1995 Period due to significant growth in
OTC securities volume.
 
  Interest, net increased to $1.3 million in 1996, from $296,000 in the 1995
Period. This increase was primarily due to larger cash balances held at banks
and the Company's clearing brokers and the exchange of $5.0 million of
subordinated notes for equity interests in the Company in January 1996, which
was offset, in part, by increased transaction-related interest expense costs
resulting from a higher level of securities sold, not yet purchased.
 
 Expenses
 
  Payments for order flow increased to $69.8 million in 1996, from $26.0
million in the 1995 Period. As a percentage of net trading revenue, payments
for order flow increased slightly to 38.0% in 1996, from 37.4% in the 1995
Period. The increase on a dollar basis and as a percentage of net trading
revenue resulted from the commencement of OTC securities market-making in July
1995, and the higher trading volumes in 1996. Payments for order flow made to
broker-dealer owners and subordinated note holders represented 66.4% of total
payments for order flow for 1996, from 55.4% in the 1995 Period.
 
  Execution and clearance fees increased to $25.8 million in 1996, from $12.7
million in the 1995 Period. As a percentage of net trading revenue, execution
and clearance fees decreased to 14.0% in 1996, from 18.3% in the 1995 Period.
The dollar increase was primarily due to increased trade volumes. The decrease
as a
 
                                      29
<PAGE>
 
percentage of net trading revenue was primarily due to strong growth in the
volume of OTC securities transactions, which have lower execution costs than
transactions in listed securities.
 
  Employee compensation and benefits expense increased to $39.5 million in
1996, from $12.2 million in the 1995 Period. As a percentage of net trading
revenue, employee compensation and benefits expense increased to 21.5% in
1996, from 17.5% in the 1995 Period. The increase on a dollar basis and as a
percentage of net trading revenue was primarily due to increased profitability
and growth in the number of employees. The number of employees increased to
195 employees as of December 31, 1996, from 152 employees as of December 31,
1995.
 
  Communications and data processing expense increased to $4.4 million in
1996, from $2.2 million in the 1995 Period. This increase was generally
attributable to higher trading volumes and an increase in the number of
employees.
 
  Depreciation and amortization expense increased to $3.0 million in 1996,
from $1.6 million in the 1995 Period. This increase was the result of the
purchase of $3.9 million of additional fixed assets and leasehold improvements
during 1996 and the amortization of goodwill related to the acquisition of the
listed securities market-making business of Trimark.
 
  Interest on Preferred Units expense increased to $2.1 million in 1996, from
$1.3 million in the 1995 Period. This increase was primarily due to the
issuance of $13.2 million Preferred A Units during 1996, which was offset in
part by the redemption and retirement of $3.9 million Preferred A Units by the
Company in April 1996.
 
  Occupancy and equipment rentals expense increased to $1.8 million in 1996,
from $849,000 in the 1995 Period. This increase was primarily attributable to
additional office space leased by the Company in 1996. The Company occupied
47,598 square feet of office space at December 31, 1996, up from 26,174 square
feet of office space at December 31, 1995.
 
  Business development expense increased to $623,000 in 1996, from $130,000 in
the 1995 Period. This increase was primarily the result of higher travel and
entertainment costs.
 
  Other expenses decreased to $1.4 million in 1996, from $1.5 million in the
1995 Period. This decrease was primarily due to higher professional fees and
promotional costs incurred in the 1995 Period in connection with the formation
of Knight and the acquisition of the listed securities market-making business
of Trimark.
 
 Income Tax
 
  Pro forma income tax expense was determined using an effective tax rate of
43% for 1996 and 46% in the 1995 Period. The effective tax rate in the 1995
Period differed from the effective rate in 1996 due to one-time nondeductible
syndication expenses incurred in the 1995 Period in connection with the
formation of the Company.

  The Company has experienced and expects to continue to experience,
significant fluctuations in quarterly operating results, including the value
of the Company's securities positions and the Company's ability to manage the
risks attendant thereto, the volume of its market-making activities,
volatility in the securities markets, its ability to manage personnel,
overhead and other expenses, the amount of revenue derived from limit orders
as a percentage of total revenues, changes in payments for order flow,
clearing costs, the addition or loss of sales and trading professionals,
regulatory changes, the amount and timing of capital expenditures, the
incurrence of costs associated with acquisitions and general economic
conditions. The Company's expense structure is based on historical expense
levels and the levels of demand for the Company's market-making services. If
demand for the Company's market-making services declines and the Company is
unable to adjust its cost structure on a timely basis, the Company's operating
results could be materially and adversely affected. The Company has
experienced, and may experience in the future, significant seasonality in its
business. The Company has historically experienced an increase in revenues in
the fourth quarter of the year, which the Company believes is due, in large
part, to higher trading volumes in the securities markets at year end. The
Company believes that this seasonal trend will continue for the foreseeable
future and that the Company's business, financial condition and operating
results may be affected by such trends in the future.
 
  Due to all of the foregoing factors, period-to-period comparisons of the
revenues and operating results of the Company are not necessarily meaningful
and such comparisons cannot be relied upon as indicators of future
performance. There also can be no assurance that the Company will be able to
sustain the rates of revenue growth that it has experienced in the past, that
it will be able to improve its operating results or that it will be able to
sustain its profitability on a quarterly basis. See "Risk Factors--Risks
Associated with Potential Fluctuations in Quarterly Results; Seasonality."
 
LIQUIDITY
 
  The Company has financed its business primarily through cash generated by
operations, as well as the private placement of preferred and common units and
borrowings under subordinated notes. As of March 31, 1998, the Company had
$171.1 million in assets, 86.0% of which consisted of cash or assets readily
convertible into cash (principally receivables from clearing brokers and
securities owned). Receivables from clearing brokers include interest bearing
cash balances held with clearing brokers and net receivables for transactions
that have not yet reached their contracted settlement date, which is generally
within three business days of the trade date. Securities owned principally
consist of equity securities which trade in NASDAQ and on the NYSE and AMEX
markets.
 
  Pro forma net income plus depreciation and amortization was $9.7 million
during the three months ended March 31, 1998, up 41.3% from $6.9 million
during the comparable period in 1997. Pro forma net income plus depreciation
and amortization was $32.8 million in 1997, up 36.9% from $23.9 million in
1996. Depreciation and amortization expense, which related to fixed assets and
goodwill, was $1.3 million for the three months ended March 31, 1998, from
$936,000 for the comparable period in 1997. Depreciation and amortization
expense was $4.2 million and $3.0 million in 1997 and 1996, respectively. The
Company's capital expenditures were $2.4 million for the three months ended
March 31, 1998 or 4% of total revenues. Capital expenditures were $5.2 million
in 1997 and $5.3 million in 1996, or 2% and 3% of total revenues in each year,
respectively. Capital expenditures in 1997 primarily related to the purchase
of data processing and communications equipment, as well as leasehold
improvements and additional office facilities to support the Company's growth.
Additionally, during 1997, the Company made cash payments of $2.4 million in
connection with its acquisitions of the listed securities market-making
businesses of Trimark in 1995 and Tradetech in 1997. The Company's aggregate
minimum rental commitments for 1998 are $3.8 million, and it expects that it
will incur $8.0 million of capital expenditures during 1998.
 
  As registered broker-dealers and market makers, Knight and Trimark are
subject to regulatory requirements intended to ensure the general financial
soundness and liquidity of broker-dealers and requiring the maintenance of
minimum levels of net capital, as defined in SEC Rule 15c3-1 ($1.0 million
each as of March 31, 1998). These regulations also prohibit a broker-dealer
from repaying subordinated borrowings, paying cash
 
                                      32
<PAGE>
 
dividends, making loans to its parent, affiliates or employees, or otherwise
entering into transactions which would result in a reduction of its total net
capital to less than 120.0% of its required minimum capital. Moreover, broker-
dealers, including Knight and Trimark, are required to notify the SEC prior to
repaying subordinated borrowings, paying dividends and making loans to its
parent, affiliates or employees, or otherwise entering into transactions,
which, if executed, would result in a reduction of 30.0% or more of their
excess net capital (net capital less minimum requirement). The SEC has the
ability to prohibit or restrict such transactions if the result is detrimental
to the financial integrity of the broker-dealer. At March 31, 1998, Knight had
net capital of $39.1 million, which was $38.1 million in excess of its required
net capital of $1.0 million and Trimark had net capital of $16.1 million, which
was $15.1 million in excess of its required net capital of $1.0 million.
 
  The Company has used a portion of its capital resources to pay interest on
its issued and outstanding Mandatorily Redeemable Preferred A and B Units, and
to make quarterly distributions to its members to meet their estimated income
tax obligations on their share of the Company's taxable income. The Preferred
A and B Units bore interest at a rate approximating the Federal Funds rate.
The Preferred A Units were redeemed and retired in their entirety in April
1998 for approximately $12.5 million in cash. In April 1998, the Company
redeemed a portion of the Preferred B Units for approximately $1.2 million in
cash. The Company intends to use $13.8 million of the proceeds of the Offering
to redeem all of the remaining outstanding Preferred B Units. See "Use of
Proceeds." After the Offering, the Company will no longer make distributions
to its owners for income tax purposes.
 
  The Company and its subsidiaries currently anticipate that net proceeds from
this Offering together with their available cash resources and credit
facilities will be sufficient to meet their anticipated working capital and
capital expenditure requirements for at least the next 12 months.
 
MARKET RISK
 
  On January 28, 1997, the SEC adopted new rules (Securities Act Release No.
7386) that require disclosures about the policies used to account for
derivatives, and certain quantitative and qualitative information about market
risk exposures. Since its inception, neither the Company or its subsidiaries
has traded or otherwise transacted in derivatives.
 
  In the normal course of its market-making business, the Company maintains
inventories of exchange-listed and OTC securities. The fair value of these
securities at March 31, 1998 and December 31, 1997 was $63.5 million and $61.7
million, respectively, in long positions and $54.6 million and $21.1 million,
respectively, in short positions. The potential loss in fair value, using a
hypothetical 10.0% decline in prices, is estimated to be approximately $1.0
million and $4.0 million as of March 31, 1998 and December 31, 1997,
respectively, due to the offset of losses in long positions with gains in
short positions.
 
  For working capital purposes, the Company invests in money market funds or
maintains interest bearing balances in its trading accounts with clearing
brokers, which are classified as cash equivalents and receivable from clearing
brokers, respectively, in the consolidated statement of financial condition.
These amounts do not have maturity dates or present a material market risk, as
the balances are short-term in nature and subject to daily repricing.
 
YEAR 2000
 
  Many currently installed computer systems and software products are coded to
accept only two digit entries in the date code field. These date code fields
will need to accept four digit entries to distinguish 21st century dates from
20th century dates. As a result, in less than two years, computer systems
and/or software used by many companies, including computers involved in the
securities industry, may need to be upgraded to comply with such "Year 2000"
requirements. The Company has undertaken a project to identify and modify non-
year 2000 compliant communications and data processing systems in anticipation
of the Year 2000. The
 
                                      33
<PAGE>
 
Company's main trading-related systems are currently Year 2000 compliant. The
Company plans to have its other computer systems certified by the end of 1998.
However, there can be no assurance that such schedule will be met or the
systems of other companies on which the Company's business is dependent also
will be converted timely or that any such failure to convert by another
company would not have an adverse effect on the Company's business. The
Company's progress under its Year 2000 compliance plan is reviewed and
monitored by senior management.
 
  The success of the Company's plan depends heavily on parallel efforts being
undertaken by other entities with which the Company's systems interact, most
notably the Company's clearing brokers and the major securities industry
service organizations, and therefore, the Company is taking steps to determine
the status of these other entities' Year 2000 compliance. The Company's plan
includes participating in industry-wide testing during the fourth quarter of
1998.
 
  The total cost of the Year 2000 project is currently estimated to be
approximately $500,000. This amount primarily represents the total estimated
man-hour costs of internal Company resources working on the Year 2000 project.
Costs related to the project are expensed as incurred, and the Company has
incurred approximately $250,000 of such costs as of March 31, 1998.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
  In June 1996, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 125, Accounting for
Transfers of Assets and Servicing of Financial Assets and Extinguishments of
Liabilities, which provides accounting and reporting standards for transfers
and servicing of financial assets and extinguishments of liabilities. On
December 31, 1996, the FASB issued SFAS No. 127, Deferral of the Effective
Date of Certain Provisions of FASB Statement No. 125, which defers the
effective date of SFAS No. 125 until January 1, 1998 for transfers which are
part of repurchase agreements, dollar-roll, securities lending or similar
transactions. The Company adopted SFAS No. 125 and SFAS No. 127 effective
January 1, 1997 and January 1, 1998, respectively. The adoption of the
provisions of these standards did not have a material impact on the Company's
financial statements.
 
  In February 1997, the FASB issued SFAS No. 128, Earnings Per Share. This
statement establishes standards for computing and presenting earnings per
share and applies to entities with publicly held common stock or potential
common stock. The Company adopted the provisions of SFAS No. 128 effective
December 31, 1997. The adoption of these provisions required the presentation
of earnings per share in the financial statements included elsewhere in this
Prospectus.
 
  In February 1997, the FASB also issued SFAS No. 129, Disclosure of
Information about Capital Structure. This statement establishes standards for
disclosing information about an entity's capital structure. The Company
adopted the provisions of SFAS No. 129 on its effective date of January 1,
1998. The adoption of these provisions did not have a material impact on the
Company's financial statements.
 
  In June 1997, the FASB issued SFAS No. 130, Reporting Comprehensive Income
which establishes standards for the reporting and display of comprehensive
income and its components. The Company adopted the provisions of SFAS No. 130
on its effective date of January 1, 1998. The adoption of these provisions did
not have any impact on the Company's financial statements.
 
  In June 1997, the FASB also issued SFAS No. 131, Disclosures about Segments
of an Enterprise and Related Information, which determines how segments are
determined and reported. The Company adopted the provisions of SFAS No. 131 on
its effective date of January 1, 1998. As the Company operates only in a
single segment and a single line of business - equity securities market-
making, the adoption of these provisions did not have any impact on the
Company's financial statements.

OVERVIEW
 
  The Company is a leading market maker in NASDAQ securities, other OTC equity
securities and equity securities listed on the NYSE and the AMEX in the Third
Market. The Company has attained this leadership position by providing best
execution services to broker-dealers and institutional customers through its
sophisticated trading systems and proprietary methods. Through its wholly-
owned subsidiary, Knight, the Company makes markets in approximately 4,200
equity securities in NASDAQ and on the OTC Bulletin Board of the NASD. The
Company, through its wholly-owned subsidiary, Trimark, makes markets in all
NYSE- and AMEX-listed equity securities in the Third Market.
 
  Since the beginning of 1997, Knight and Trimark have significantly increased
their market share of trading volume in each of their respective markets.
According to AutEx, Knight's advertised share volume in NASDAQ increased from
614.7 million shares representing 4.4% of total market share (or a rank of 6th
overall) for the month of January 1997, to 1.2 billion shares representing
8.1% of total market share (or a rank of 2nd overall) for the month of
December 1997, to 1.9 billion shares representing 9.9% of total market share
(or a rank of 1st overall) for the month of March 1998. According to the NASD,
Trimark's reported share volume of the NYSE-listed securities increased from
234.2 million shares representing 21.2% of total NYSE Third Market volume (or
a rank of 1st overall) for the month of January 1997, to 338.4 million shares
representing 30.5% of total NYSE Third Market volume (or a rank of 1st
overall) for the month of December 1997, to 445.6 million shares representing
33.1% of total NYSE Third Market volume (or a rank of 1st overall) for the
month of March 1998. Trimark's reported share volume of AMEX-listed securities
increased from 40.2 million shares representing 51.4% of total AMEX Third
Market volume (or a rank of 1st overall) for the month of January 1997, to
78.7 million shares representing 66.4% of total AMEX Third Market volume (or a
rank of 1st overall) for the month of December 1997, to 80.4 million shares
representing 68.9% of total AMEX Third Market volume (or a rank of 1st
overall) for the month of March 1998.
 
INDUSTRY BACKGROUND
 
  During recent years, the U.S. market for equity securities has experienced
dramatic growth in trading volumes. The average daily volume of securities
traded in NASDAQ increased from 225.0 million shares in December 1992 to 678.5
million shares in December 1997. The average daily volume of securities traded
on the NYSE increased from 222.2 million shares in December 1992 to 546.9
million shares in December 1997. During this period, the average daily trading
volume of the Third Market, which consists of trading in NYSE- and AMEX-listed
securities in the OTC market, also increased significantly. The increase in
trading volume has resulted from a number of factors, including the growth of
cash flows into equity-based mutual funds, historic high returns in U.S.
equity markets, the emergence and market acceptance of electronic discount
brokers, technological innovations, such as the emergence of the Internet, and
reduced transaction costs. In addition, due to favorable market conditions,
companies have increasingly raised capital through the U.S. equity markets,
which has resulted in a significant increase in the number of companies that
are quoted in NASDAQ or listed on the NYSE. At March 31, 1998, there were
approximately 5,500 and 3,046 companies, respectively, quoted in NASDAQ and
listed on the NYSE, as compared to approximately 4,100 and 2,008 at December
31, 1992.
 
  The retail brokerage business has been impacted by advances in technology
that have provided new and inexpensive means for individual investors to
access and participate in the market for equity securities. For example, the
Internet has facilitated individual investors' access to market information
and has significantly reduced transaction costs. The proliferation of Internet
brokers has resulted in dramatically lowered commissions charged for trading
securities. For example, some Internet brokers charge less than $10.00 per
trade for a 1,000 share trade compared to over $300.00 per trade for some
traditional "full service" brokers. While handling an increasing number of
trades for a wide range of securities, Internet brokers provide more
 
                                      35
<PAGE>
 
immediate access to the market place than many other retail brokers.
Additionally, mutual funds and other institutional investors are also
demanding better execution of their trades and are seeking to reduce trading
costs. The Internet brokerage business model and the demands of institutional
investors have forced traditional brokers to change their approach to their
business and seek ways to manage increased trading volumes while providing
improved trade execution and reducing costs.
 
  These changes have caused significant pressure on market makers, a critical
and lesser known part of the securities industry. Market makers typically
provide trading execution by offering to buy securities from, or sell
securities to, broker-dealers and institutional investors. Firms that have
elected to make a market in a security display the price at which they are
willing to buy (bid) or sell (ask) these securities and adjust their bid and
ask prices in response to the forces of supply and demand for each security.
Market makers are either a department within larger, diversified securities
firms or independent businesses. The internal market-making departments of
securities firms often are limited in their ability to handle significant
trading volumes in a broad range of securities and, as a result, are often
unable to provide adequate or enhanced liquidity. Most discount brokers and
on-line brokers do not have internal market-making functions and, accordingly,
rely entirely on independent market makers for trade execution.
 
  A market maker typically acts as principal and derives most of its revenues
from the difference between the price paid when a security is bought and the
price received when that security is sold. In the past, market makers relied
on the spreads between bid and ask prices to ensure profitability and built
cost structures based on these spreads. However, changes in regulations
governing the securities industry and, to a lesser extent, the move from
securities being quoted in sixteenths rather than eighths of a dollar, have
dramatically reduced average spreads. Implemented in January 1997, the SEC's
Limit Order Display Rule requires the display or execution of customer limit
orders (orders to buy or sell stock at a particular price) that (1) are priced
better than a market maker's quote or (2) in certain circumstances add to the
size associated with the market maker's quote when the market maker is at the
best price in the market. The Limit Order Display Rule enables investors to
advertise directly their trading interest to the market, thereby allowing them
to compete with market maker quotes and affect the size of bid-ask spreads.
Additional regulations adopted by the NASD require market makers to fill a
customer's limit order before their own trades. Since the implementation of
the Limit Order Display Rule and the move to trading in sixteenths of a
dollar, NASDAQ and NYSE spreads have each decreased by an average of 35%.
Spreads could further decline if NASDAQ adopts proposed regulations under
which securities would be traded in decimals rather than in fractions.
 
  In this new narrower spread environment, maintaining profitability has
become extremely difficult for many traditional marker makers. At the same
time, market makers have become subject to an increasing demand for better
execution standards and improved customer service. To meet these demands and
remain competitive, market makers have been forced to reexamine their
traditional spread-based approach to market making and to make extensive
technological and human resource investments. To leverage these large
investments and to remain profitable, market makers must execute a larger
volume of trades and maintain increased inventory positions. However, the
significant increases in trading volumes are only a benefit for the market
maker if its cost per trade is lower than its revenues per trade and if the
market maker is able to manage the risks associated with larger inventory
positions.
 
  In response to these challenges, traditional brokerage firms are
increasingly electing to focus on their core competencies and to outsource
their market-making functions to independent market makers. In addition,
Internet brokers, who are handling increased trading volume, also utilize
independent market makers. According to AutEx, in March 1998, the three
largest independent market makers represented a combined market share of 25.4%
of the trading volumes of OTC equity securities, up from 17.2% in March 1997.
Similarly, according to the NASD, in March 1998 the three largest Third Market
trading firms represented a combined market share of 58% of the Third Market
volume in NYSE-listed equity securities compared to 42% in June 1997. The
three largest Third Market trading firms in AMEX-listed securities represented
a combined market share of 75% in March 1998 compared to 55% in June 1997.
While large volumes of trading provides an opportunity to spread fixed costs
over a larger number of trades, net profit per
 
                                      36
<PAGE>
 
trade has declined. Certain independent market makers are seeking new trading
methodologies to identify and take advantage of the profit opportunities
represented by each trade. These market makers are also seeking to increase
the number of buy and sell orders that they receive ("order flow") which, in
turn, will provide increased trading profit opportunities. These market makers
require efficient and sophisticated systems and risk management practices and
personnel with the requisite expertise to deliver superior trade execution and
customer service, while handling increased order flow and maintaining low
costs per trade.
 
THE KNIGHT/TRIMARK SOLUTION
 
  The Company is a leading market maker in NASDAQ securities, other OTC equity
securities and equity securities listed on the NYSE and the AMEX in the Third
Market. The Company has attained a leadership position by providing best
execution services to broker-dealer and institutional customers through its
sophisticated trading systems and proprietary methods. Through Knight, the
Company makes markets in approximately 4,200 equity securities in NASDAQ and
on the NASD's OTC Bulletin Board. The Company, through Trimark, makes markets
in all NYSE- and AMEX-listed equity securities in the Third Market. The
Company is committed to providing a value-added execution methodology that
emphasizes automated execution and rule compliance, real-time information
access to customers and pricing plus liquidity advantages based upon the
Company's willingness to commit capital. The main elements of the Company's
solution include:
 
 .  Superior Execution and Enhanced Liquidity. The Company has implemented a
   variety of best execution practices which meet or exceed customer
   requirements and provide its customers with significantly enhanced
   liquidity, while complying with SEC and NASD regulations. These practices
   include the following:
 
  Knight
 
  - Knight provides guaranteed, automated, electronic, continuous execution
    for over 3,000 NASDAQ securities in which it makes markets for orders of
    up to 2,000-3,000 shares on quotes as low as 100 shares.
 
  - Knight, a year prior to the implementation of the SEC's Limit Order
    Display Rule, established a policy of displaying all unexecuted limit
    orders for 2,000 shares or greater.
 
  - In March 1998, for securities in which Knight was a market maker, 99.9%
    of all orders eligible for automated execution were executed within 3
    seconds.
 
  - Knight was the first, and remains the only, market maker to guarantee
    execution, at the opening, of market-eligible orders it has received
    before the opening for all shares in which it makes a market, up to an
    aggregate of 250,000 shares.
 
  - Knight guarantees that it will execute trades at the opening price for
    substantially all NASDAQ initial public offerings, up to an aggregate of
    250,000 shares.
 
  - Knight has considerable expertise in handling large trades and, in March
    1998, it executed 80,559 trades of 5,000 shares or greater.
 
  - Knight was the first market maker to accept stop orders on all NASDAQ
    stocks. A stop order is an order to buy/sell a security immediately if
    the security's market price falls/rises to a specified price.
 
  Trimark
 
  - Trimark provides guaranteed, automated, electronic, continuous execution
    in every NYSE- and AMEX-listed equity security at the National Best Bid
    or Offer ("NBBO") for all orders eligible for automated execution.
 
  - Trimark accepts all orders that can be sent to a primary exchange, i.e.
    short sale, all or none, or stop order.
 
                                      37
<PAGE>
 
  - Trimark provides execution for orders up to 5,000 shares at the NBBO
    regardless of the quote's size for a select group of over 500 of the most
    actively traded stocks, representing more than 75% of NYSE volume.
 
  - Trimark not only guarantees the customer's market order to receive the
    best price available on any exchange or by any competing market maker,
    but Trimark frequently delivers that price for many more shares than
    advertised if demanded by the customer.
 
  - Trimark offers various proprietary features such as limit order execution
    protection based on the primary exchange and price improvement
    guarantees.
 
 .  Commitment to Highest Quality Customer Service. The Company is committed to
   providing the highest quality customer service. The Company believes that
   its highly skilled, experienced and entrepreneurial workforce is uniquely
   positioned to address the needs of its customers. The Company has 49
   employees involved in customer service, with an average of 7.5 years of
   related experience. The Company's customer service group is dedicated to
   handling orders greater than the automated execution size and ensuring
   consistent quality of execution.
 
  The Company is currently implementing its proprietary electronic
  communications gateway product, "e.Knight," which enables broker-dealers
  and institutions to access the Knight and Trimark trading systems from
  their desktops through the Internet and other electronic communications
  gateways. In addition, e.Knight provides a backup service to certain of the
  Company's customers. If a customer's system fails, e.Knight provides the
  customer with uninterrupted access to the Company's trading systems and
  thereby enables the customer to continue to provide services to its
  clients.
 
  The Company supplies each of its customers with monthly execution reports
  that provide a level of detail exceeding regulatory requirements. The
  report documents the percentage of price-improved shares and trades, the
  average dollar value per share and the total dollar value of all price
  improvements. This report is a valuable tool to the Company's customers as
  it enables them to monitor their compliance with regulatory requirements to
  seek and obtain best execution for their clients' trades.
 
 .  Sophisticated Trading Technology. The Company relies on sophisticated
   technology to facilitate its market-making activities. Knight uses the
   Brass trading system under license from Automated Securities Clearance,
   Ltd. ("ASC"). Brass is used by over 130 market makers. Knight is one of
   only two Brass users to run Brass on its own computers with its own
   personnel, while all other market makers use ASC as a service bureau.
   Trimark employs a TCAM/Appletree trading system. The Company has made
   significant investments in its technology platform and infrastructure since
   its inception. The Company's trading systems are augmented by software
   applications that enable the processing of a large volume of order flow
   efficiently, without diminishing speed of execution. The Company's systems
   are designed to process up to 500,000 trades per day and in March, 1998
   handled a combined average of 134,000 trades per day.
 
 .  Proprietary Trading Methods. The Company's net trading revenues are
   dependent on its ability to evaluate and act rapidly on market trends and
   successfully manage risk. The Company's methodology focuses on the dynamic,
   real time analysis of market activity and price movements, which enables
   the Company to better manage risk. Throughout the business day, the Company
   continually analyzes its trading positions in individual securities and
   monitors its short and long positions and its aggregate profits and losses.
   Management uses this information to assess market trends and adjust its
   trading strategy on a real time basis in an effort to maximize its trading
   profits.

STRATEGY
 
  The Company's goal is to maintain and enhance its leadership position in the
market-making industry through the following key strategies:
 
  Continue to Invest in Leading Technologies. The Company believes that its
future growth and profitability will depend largely on its continued
investment in leading technologies. For example, the Company believes that an
increasing number of customers and proportion of order flow will reach market
makers through the Internet and other electronic communications gateways. The
Company intends to expand into this growing market segment by increasing the
number of customers with access to e.Knight and by examining other possible
electronic means of capturing order flow. The Company also intends to augment
its Brass and TCAM/Appletree trading systems with proprietary software
applications to ensure that it has the capability to process greater trading
volumes in the future.
 
  Aggressively Capture New Order Flow. The Company believes that extensive
order flow is critical to creating opportunities for trading revenues. The
Company is focused on increasing order flow to enhance its position as a
leading market maker and create additional revenue opportunities. The Company
intends to retain and expand customer relationships by continuing to provide
low-cost, high quality execution services, and intends to continue to respond
to evolving customer needs through the development of new services and
customer service excellence. Knight is seeking regulatory approval to increase
the number of securities in which it is allowed to make a market.
 
  Significantly Expand Institutional Market Share. The Company believes it has
an opportunity to significantly increase its institutional customer base.
Trades for institutional investors generally have higher margins because these
investors do not receive payments for order flow. The Company is seeking to
increase its penetration of this market by marketing e.Knight to institutions
that manage more than $1 billion in assets and invest predominantly in equity
securities. In addition, within the next 18 months, the Company also plans to
significantly increase its institutional sales force.
 
  Invest in and Develop the Best Human Capital. The Company believes that
investing in human capital is key to delivering best execution practices and
high quality customer service. The Company intends to continue its practice of
aggressively recruiting high caliber personnel and retaining such personnel by
providing appropriate compensation incentives. The Company believes that it
has high employee morale due to its competitive performance-based incentive
compensation structure and its encouragement of a highly cooperative and
creative culture. In addition, Knight has its own in-house training program
for trading staff, Knight School, which provides ongoing training and skill-
development to Knight's sales and trading personnel. The Company intends to
expand this initiative and to develop additional programs to improve the
skills and productivity of its workforce.
 
  Develop New Services. The Company intends to continue to develop new
services that address evolving customer needs and technological requirements.
The Company recently launched e.Knight, which it plans to provide to the
majority of its institutional and broker-dealer customers and use as a means
of establishing new customer relationships. The Company also plans to
introduce additional services to support customers in executing equity
transactions. For example, the Company has recently developed an Electronic
Communications Network ("ECN") for order execution in a joint venture with a
wholly-owned subsidiary of ASC. The Company believes that this ECN product
will greatly enhance the breadth of the Company's execution services.
 
  Leverage Cross-Selling Opportunities. The Company jointly markets Knight and
Trimark to offer market-making services for a broad range of securities to its
customers. The Company believes that by creating customer awareness of the
link between the two companies, customer satisfaction in one market can lead
to increased use of the Company's services in other markets. In addition,
customers with the e.Knight gateway will have real-time access to both
Knight's and Trimark's services at their desktops and will be targeted for
cross-selling opportunities.

ELECTRONIC COMMUNICATIONS NETWORK
 
  ECNs are private trading systems which are popular among institutional
investors and traders because they provide investors with the ability to trade
securities anonymously. ECNs currently account for approximately 20% of the
NASDAQ trading volume.
 
  The Company has entered into a joint venture with ASC, the developer and
owner of the Brass order entry and trading system, to establish an ECN. The
Company owns 20% of the joint venture entity, Brass Utility, L.L.C. ("BRUT").
The Company believes that access to the BRUT ECN will greatly enhance the
breadth of the Company's execution services.

MARKETING
 
  The Company seeks to increase its market share through direct-response
advertising, advertising on its Web site and a public relations program. The
Company's marketing focuses on advertising its execution services in
publications targeted at the securities industry. In addition, the Company has
a quarterly program of targeted mailings to existing and potential broker-
dealer and institutional customers.
 
  The Company also markets aggressively through one-on-one meetings with
customers and potential customers, and continuous communications with existing
customers. The Company maintains a comprehensive customer database that is
used regularly to better understand and address customer needs. The Company's
marketing strategy is to continue to differentiate itself from competitors by
enhancing its reputation and brand as the provider of highest quality
execution solutions with superior customer service.
 
CLEARING ARRANGEMENTS
 
  By contract, Knight clears all its trades through Correspondent Services
Corp., a subsidiary of PaineWebber Incorporated ("PaineWebber"). The contract

See "Certain Transactions."

<PAGE>
 
TECHNOLOGY
 
  The Company's success is largely attributable to management's ability to
identify and deploy emerging technologies that facilitate the execution of
trades. Technology has not only enhanced the Company's ability to handle order
flow, it has also been an important component of the Company's strategy to
comply with government regulations, achieve the highest execution standards
and provide superior customer service. The Company also uses its technology
and technology licensed from third parties to monitor proactively the
performance of its traders and to assess its inventory positions and to
provide ongoing information to its customers. The Company is electronically
linked to its broker-dealer and institutional customers through dedicated
servers. The Company's trading volume is transacted over dedicated
communications networks, which provide immediate access to the Company's
trading operations and facilitate the handling of customer orders. The Company
plans to continue to make additional investments in technology and to automate
further its execution services.
 
  Architectural Design and Industry Standards. The Company's systems are
designed to be open, interoperable, scalable, redundant and flexible. The
Company utilizes leading edge technologies including Sun Microsystems, Inc.'s
client/server architecture, C/C++ programming languages, Java, relational
database management systems and online analytical processing.
 
  Electronic Commerce. The Company's electronic commerce architecture enables
its broker-dealer and institutional customers to send their orders through a
variety of electronic communications gateways, including the Internet and
direct customer interfaces over the Company's private network. The Company's
customers can use their own order management system, an institutional
portfolio management system or can select from a variety of the Company's
electronic connections.
 
  Knight uses the Brass trading system designed by ASC. This system has a
client/server architecture that uses Sun Microsystems, Inc. workstations and
servers. Knight runs a local version of Brass. Knight also makes extensive use
of application program interfaces ("APIs") to develop software applications.
Trimark uses the Appletree trading system designed by TCAM. This system runs
on Stratus Computer Inc.'s fault tolerant platform. Trimark has also developed
software applications using APIs.
 
  Disaster Recovery Center. The Company is in the process of establishing a
back-up data center and trading facility in Ridgefield, New Jersey. This
facility will be used primarily to accommodate traders if a disaster or major
system malfunction occurs. This back-up data center will run a real-time copy
of the Company's trading systems and house a small group of full-time traders.
To provide for system continuity in the event of short power outages, the
Company has also equipped its three data centers and trading rooms with
uninterruptible power supply units and back up generators.
 
COMPETITION
 
  The Company derives substantially all of its revenues from market-making
activities. The market for these services, particularly market-making services
through electronic communications gateways, is rapidly evolving and intensely
competitive. The Company expects competition to continue and intensify in the
future. Knight competes primarily with wholesale, national, and regional
broker-dealers. Trimark competes with the NYSE, the AMEX, regional exchanges
and Third Market competitors. The Company competes primarily on the basis of
execution standards, its relationship with its customers and technology.
 
  A number of the Company's competitors have significantly greater financial,
technical, marketing and other resources than the Company. Some of the
Company's competitors also offer a wider range of services and products than
the Company and have greater name recognition and more extensive customer
bases than the Company. These competitors may be able to respond more quickly
to new or evolving opportunities, technologies and customer requirements than
the Company and may be able to undertake more extensive promotional activities
and offer more attractive terms to customers. Recent advancements in computing
and communications technology are substantially changing the means by which
market-making services are
 
                                      42
<PAGE>
 
delivered, including more direct access on-line to a wide variety of services
and information, and have also created demand for more sophisticated levels of
customer service. The provision of such services may entail considerable cost
without an offsetting increase in revenues. Moreover, current and potential
competitors have established or may establish cooperative relationships among
themselves or with third parties or may consolidate to enhance their services
and products. New competitors or alliances among competitors may emerge and
they may acquire significant market share.
 
  There can be no assurance that the Company will be able to compete
effectively with current or future competitors or that the competitive
pressures faced by the Company will not have a material adverse effect on the
Company's business, financial condition and operating results.
 
EMPLOYEES
 
  At March 31, 1998 the Company had a total of 337 full-time employees, of
which 246 were employed at Knight and of which 91 were employed at Trimark. Of
Knight's 246 employees, 142 were engaged in market-making activities, 33 in
customer service and 71 in administration. Of Trimark's 91 employees, 55 were
engaged in market-making activities, 16 in customer service and 20 in
administration. None of the Company's employees are subject to a collective
bargaining agreement. The Company believes that its relations with its
employees are excellent.
 
  The Company recruits and retains its employees by compensating them largely
on a performance basis, measuring performance primarily in terms of revenue
generation. The Company is committed to improving the skill levels of its
employees and, to that end, Knight has established Knight School, a weekly
training session in which trading staff learn new trading techniques and are
informed of regulatory developments. The Company intends to expand this
initiative and to develop additional programs to improve the skills and
productivity of its workforce. The Company believes that it has high employee
morale due to its performance-based incentive compensation and its
encouragement of a highly cooperative and creative culture.
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
  The Company relies primarily on copyright, trade secret and trademark law to
protect its proprietary technology. Notwithstanding the precautions taken by
the Company to protect its intellectual property rights, it is possible that
third parties may copy or otherwise obtain and use the Company's proprietary
technology without authorization or otherwise infringe on the Company's
proprietary rights. It is also possible that third parties may independently
develop technologies similar to those of the Company. It may be difficult for
the Company to police unauthorized use of its intellectual property rights.
There can be no assurance that the steps taken by the Company will prevent
misappropriation of its technology. In addition, litigation may be necessary
in the future to enforce the Company's intellectual property rights, to
protect the Company's trade secrets, to determine the validity and scope of
the proprietary rights of others, or to defend against claims of infringement
or invalidity. Such litigation, whether successful or unsuccessful, could
result in substantial costs and diversions of resources either of which could
have a material adverse effect on the Company's business, financial condition
and operating results. The Company may in the future receive notices of claims
of infringement of other parties' proprietary rights. There can be no
assurance that claims for infringement or invalidity (or claims for
indemnification resulting from infringement claims) will not be asserted or
prosecuted against the Company. Any such claims, with or without merit, could
be time consuming to defend, result in costly litigation, divert management's
attention and resources or require the Company to enter into royalty or
licensing agreements. There can be no assurance that such royalties or
licenses would be available on reasonable terms, if at all, and the assertion
or prosecution of any such claims could have a material adverse effect on the
Company's business, financial condition and operating results.
 
GOVERNMENT REGULATION
 
  The securities industry in the United States is subject to extensive
regulation under both federal and state laws. In addition, the SEC, the NASD,
other SROs, such as the various stock exchanges, and other regulatory
 
                                      43
<PAGE>
 
bodies, such as state securities commissions, require strict compliance with
their rules and regulations. As a matter of public policy, regulatory bodies
are charged with safeguarding the integrity of the securities and other
financial markets and with protecting the interests of customers participating
in those markets, not protecting creditors or stockholders of market makers.
Market makers are subject to regulation concerning certain aspects of their
business, including trade practices, capital structure, record retention and
the conduct of directors, officers and employees. Failure to comply with any
of these laws, rules or regulations could result in censure, fine, the
issuance of cease-and-desist orders or the suspension or disqualification of
its directors, officers or employees, and other adverse consequences, which
could have a material adverse effect on the Company's business, financial
condition and operating results. The Company and certain of its officers and
other employees have, in the past, been subject to claims arising from the
violation of such laws, rules and regulations, which resulted in the payment
of fines and settlements. There can be no assurance that the Company and/or
its officers and other employees will not, in the future, be subject to claims
arising from the violation of such laws, rules and regulations. An adverse
ruling against the Company and/or its employees, including censure or
suspension, could result in the Company and/or its officers and other
employees being required to pay a substantial fine or settlement, and could
result in their suspension or expulsion, which could have a material adverse
effect on the Company's business, financial condition and operating results.
 
  In connection with a three-year industry-wide investigation conducted by the
staff of the SEC into the trading and supervisory activities of many OTC
market makers and certain of their individual supervisory and trading
personnel, in July, 1997, the Staff informed Kenneth Pasternak, President and
Chief Executive Officer of the Company, that he is a subject in their
investigation for certain of his activities as a trading room supervisor at
Troster Singer. All of the activities being investigated took place prior to
Mr. Pasternak joining the Company in 1995 and none of them relate to his
employment by the Company. Mr. Pasternak has also been orally informed by the
Staff that, as a result of its investigation, it currently intends to
recommend to the SEC that Mr. Pasternak be charged with failure to supervise
with respect to several transactions of other traders under his supervision at
Troster Singer and that Mr. Pasternak be suspended for six months, ordered to
cease and desist, and assessed a civil penalty of $50,000. In September, 1997,
Mr. Pasternak submitted a brief to the Staff arguing that these
recommendations would be inappropriate and unsupported by the facts. To date,
the Staff has not forwarded its recommendations to the SEC. The Company cannot
predict the outcome of the Staff's investigation, including whether the Staff
will determine to forward its recommendations to the SEC in their current or a
modified form or at all. If any such charges are brought, Mr. Pasternak
intends to vigorously defend himself against them. If Mr. Pasternak should be
suspended, the Company would seek to replace his services with other Company
personnel. However, the loss of Mr. Pasternak's services would have a material
adverse effect on the Company's business, financial condition and operating
results.
 
  The regulatory environment in which the Company operates is subject to
change. The Company's business, financial condition and operating results may
be adversely affected as a result of new or revised legislation or regulations
imposed by the SEC, other United States or foreign governmental regulatory
authorities or the NASD. The Company's business, financial condition and
operating results also may be adversely affected by changes in the
interpretation or enforcement of existing laws and rules by these governmental
authorities and the NASD.
 
  Additional regulation, changes in existing laws and rules, or changes in
interpretations or enforcement of existing laws and rules often directly
affect the method of operation and profitability of securities firms. The
Company cannot predict what effect any such changes might have. Furthermore,
the Company's business, financial condition and operating results may be
materially affected not only by regulations directly applicable to it, but
also by regulations of general application. For example, the volume of the
Company's market-making activities in a given period could be affected by,
among other things, existing and proposed tax legislation, antitrust policy
and other governmental regulations and policies (including the interest rate
policies of the Federal Reserve Board) and changes in interpretation or
enforcement of existing laws and rules that affect the business and financial
communities. The level of trading and market-making activity can be affected
not only by such legislation or regulations of general applicability, but also
by industry-specific legislation or regulations.
 
                                      44
<PAGE>
 
  The Company's market-making activities involve securities traded in NASDAQ.
NASDAQ's operations have been the subject of extensive scrutiny in the media
and by government regulators, including the Antitrust Division of the United
States Department of Justice. This scrutiny has included allegations of
collusion among NASDAQ market makers. In fact, a large group of NASDAQ market
makers recently entered into a Stipulation and Order with the Department of
Justice in which they agreed not to engage in any collusive activities relating
to prices, quotes or spreads in NASDAQ-traded securities. In August 1996, the
SEC adopted certain new rules and rule amendments, known as the Order Handling
Rules, which significantly altered the manner in which orders related to both
NASDAQ and listed securities are handled. The implementation of these rules
began in January 1997. The SEC has also issued for comment certain proposed
rules by the NASD which, if approved, would introduce a new system for
delivering and executing orders in NASDAQ. The proposed NASD rules, if
approved, along with other potential regulatory actions and improvements in
technology, could impact the manner in which business is currently conducted in
NASDAQ. These new rules, regulatory actions, and changes in market customs and
practices could have a material adverse effect on the Company's business,
financial condition and operating results.

 The Company's business, both directly and indirectly, relies on the Internet
and other electronic communications gateways. The Company intends to expand
use of such gateways. To date, the use of the Internet has been relatively
free from regulatory restraints. However, the SEC, certain SROs and certain
states are beginning to address the regulatory issues that may arise in
connection with the use of the Internet. Accordingly, new regulations or
interpretations may be adopted that constrain the Company's and its customers'
ability to transact business through the Internet or other electronic
communications gateways. Any additional regulation of the use of such gateways
could have a material adverse effect on the Company's business, financial
condition and operating results.
 
  In addition, the Company may in the future expand its business to other
countries. To expand its services internationally, the Company would have to
comply with regulatory controls of each specific country in which it conducts
business. The brokerage industry in many foreign countries is heavily
regulated. The varying compliance requirements of these different regulatory
jurisdictions and other factors may limit the Company's ability to expand
internationally. There can be no assurance that the Company will be successful
in obtaining the necessary regulatory approvals for any such expansion, or if
such approvals are obtained, that the Company will be able to continue to
comply with such regulations. The failure to obtain or comply with such
approvals could have a material adverse effect on the Company's business,
financial condition and operating results. See "Business--Government
Regulation."
 
NET CAPITAL REQUIREMENTS
 
  As registered broker-dealers and members of the NASD, the Company's
subsidiaries are subject to the Net Capital Rule. The Net Capital Rule, which
specifies minimum net capital requirements for registered brokers-dealers, is
designed to measure the general financial integrity and liquidity of a broker-
dealer and requires that at least a minimum part of its assets be kept in
relatively liquid form. In general, net capital is defined as net worth
(assets minus liabilities), plus qualifying subordinated borrowings and
certain discretionary liabilities, and less certain mandatory deductions that
result from excluding assets that are not readily convertible into cash and
from valuing conservatively certain other assets. Among these deductions are
adjustments (called "haircuts"), which reflect the possibility of a decline in
the market value of an asset prior to disposition.
 
  Failure to maintain the required net capital may subject a firm to
suspension or revocation of registration by the SEC and suspension or
expulsion by the NASD and other regulatory bodies and ultimately could require
the firm's liquidation. The Net Capital Rule prohibits payments of dividends,
redemption of stock, the prepayment of subordinated indebtedness and the
making of any unsecured advance or loan to a stockholder, employee or
affiliate, if such payment would reduce the firm's net capital below required
levels.
 
  The Net Capital Rule also provides that the SEC may restrict for up to 20
business days any withdrawal of equity capital, or unsecured loans or advances
to stockholders, employees or affiliates ("capital
 
                                      45
<PAGE>
 
withdrawal"), if such capital withdrawal, together with all other net capital
withdrawals during a 30-day period, exceeds 30% of excess net capital and the
SEC concludes that the capital withdrawal may be detrimental to the financial
integrity of the broker-dealer. In addition, the Net Capital Rule provides
that the total outstanding principal amount of a broker-dealer's indebtedness
under certain subordination agreements, the proceeds of which are included in
its net capital, may not exceed 70% of the sum of the outstanding principal
amount of all subordinated indebtedness included in net capital, par or stated
value of capital stock, paid in capital in excess of par, retained earnings
and other capital accounts for a period in excess of 90 days.
 
  A change in the Net Capital Rule, the imposition of new rules or any
unusually large charge against net capital could limit those operations of the
Company that require the intensive use of capital and also could restrict the
Company's ability to withdraw capital from its broker-dealer subsidiaries,
which in turn could limit the Company's ability to pay dividends, repay debt
and repurchase shares of its outstanding stock. A significant operating loss
or any unusually large charge against net capital could adversely affect the
ability of the Company to expand or even maintain its present levels of
business, which could have a material adverse effect on the Company's
business, financial condition and operating results.
 
RISK MANAGEMENT
 
  The Company's market-making and trading activities expose the Company's
capital to significant risks. These risks include, but are not limited to,
absolute and relative price movements, price volatility or changes in
liquidity, over which the Company has virtually no control.
 
  The Company employs an automated proprietary trading and risk management
system which provides real time, on-line risk management and inventory
control. The Company monitors its risks by a constant review of trading
positions. For each trader, the Company has established a system whereby any
trades that exceed pre-determined limits are monitored by senior management as
are individual and aggregate dollar and share position totals and real-time
profits and losses. The management of trading positions is enhanced by review
of mark-to-market valuations and/or position summaries on a daily basis. The
following table illustrates the number of trading days the Company earned net
trading revenues or net trading losses for the respective periods.

BOARD COMMITTEES
 
  The Board of Directors has created an Audit Committee and a Compensation
Committee of the Board. The Audit Committee was established in April, 1998 and
is charged with reviewing the Company's annual audit and meeting with the
Company's independent accountants to review the Company's internal controls
and financial management practices. As of the date of this Prospectus, the
Audit Committee is composed of Gary R. Griffith, Joseph A. Konen and Bruce R.
McMaken. The Compensation Committee, was established in April 1998, and is
charged with recommending to the Board of Directors compensation for the
Company's key employees and will administer the 1998 Stock Option and Award
Plan. As of the date of this Prospectus, the Compensation Committee is
composed of Martin Averbuch, Charles V. Doherty and Gene L. Finn. See "--Stock
Option Plan."
 
DIRECTOR COMPENSATION
 
  Non-employee directors will receive $18,000 per year, with committee
chairpersons receiving an additional $3,000 per year, in addition to $1,000
for each Board or Committee Meeting attended. Each non-employee director will
receive stock options pursuant to the automatic option grant provisions of the
Company's Stock Incentive Plan. See "--Nonemployee Director Stock Option
Plan." All directors will receive reimbursement of reasonable out-of-pocket
expenses incurred in connection with meetings of the Board of Directors. No
director who is an employee of the Company will receive compensation for
services rendered as a director.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  During 1997, and prior to the formation of the Compensation Committee,
decisions concerning the compensation of executive officers were made by the
entire Board of Directors. As of the date of this Prospectus, the Company's
Compensation Committee consists of Messrs. Averbuch, Doherty and Finn, none of
whom has ever been an officer or employee of the Company. No executive officer
of the Company serves as a member of the board of directors or compensation
committee of any entity that has one or more executive officers serving as a
member of the Company's Board of Directors or Compensation Committee. Certain
members of the Company's Board of Directors are parties to transactions with
the Company. See "Certain Transactions."
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
  The Company utilizes certain provisions in Delaware corporate law to limit
the liability of corporate officers and directors. The Company believes that
the provisions of its Certificate of Incorporation and Bylaws and the separate
indemnification agreements outlined below are necessary to attract and retain
qualified persons as directors and officers. The Company's Certificate of
Incorporation limits the liability of directors to the maximum extent
permitted by Delaware law. This provision is intended to allow the Company's
directors the benefit of Delaware General Corporation Law, which provides that
directors of Delaware corporations may be relieved of monetary liabilities for
breach of their fiduciary duties as directors, except under certain
circumstances, including breach of their duty of loyalty, acts or omissions
not in good faith or involving intentional misconduct or a knowing violation
of law, unlawful payments or dividends or unlawful stock repurchases or
redemptions or any transaction from which the director derived an improper
personal benefit. The Company's Bylaws provide that the Company shall
indemnify officers and directors to the fullest extent provided by Delaware
law. The Bylaws authorize the use of indemnification agreements and the
Company intends to enter into such agreements with each of its directors and
executive officers.
 
  The Company intends to obtain officer and director liability insurance with
respect to liabilities arising out of certain matters, including matters
arising under the Securities Act.
 
  There is no pending litigation or proceeding involving a director, officer,
associate or other agent of the Company as to which indemnification is being
sought, nor is the Company aware of any threatened litigation that may result
in claims for indemnification by any director, officer, associate or other
agent.

  KNIGHT/TRIMARK GROUP, INC. 1998 LONG-TERM INCENTIVE PLAN. The Company, with
the approval of its stockholders, has adopted the 1998 Long-Term Incentive
Plan (the "1998 Plan"). The 1998 Plan will take effect prior to the
consummation of this Offering. A maximum of 7,145,000 shares of Common Stock
has been reserved for issuance under the 1998 Plan, subject to equitable
adjustment upon the occurrence of any increase in, decrease in or exchange of
the outstanding shares of Common Stock through merger, consolidation,
recapitalization, reclassification, stock split, stock dividend or similar
corporate transaction.
 
  The 1998 Plan will be administered by a committee established by the Board
of Directors, the composition of which will at all times satisfy the
provisions of Rule 16b-3 of the Securities Exchange Act of 1934, as in effect
from time to time, including any successor thereof (the "Committee"). The
Committee will have full authority, subject to the provisions of the 1998
Plan, to determine, among other things, the persons to whom awards under the
1998 Plan ("Awards") will be made, the size of such Awards, and the specific
terms and conditions applicable to Awards, including, but not limited to, the
duration, vesting and exercise or other realization periods, the circumstances
for forfeiture and the form and timing of payment. The 1998 Plan limits the
number of shares of Common Stock that may be the subject of Awards to any
grantee in any calendar year to 1 million.
 
  Awards, including stock options ("Options"), and restricted stock
("Restricted Stock"), and restricted stock units ("Restricted Stock Units")
may be made under the 1998 Plan to selected employees and independent
contractors of the Company and its present or future subsidiaries and
affiliates, in the discretion of the Committee. Approximately 300 employees
will be eligible to receive Awards under the 1998 Plan. Stock options may be
either "incentive stock options," as such term is defined in Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code"), or nonqualified
stock options. The exercise price of an Option will not be less than the fair
market value per share of Common Stock on the date of grant. The exercise
price of an Option may be paid in cash or Common Stock or pursuant to a
"broker's cashless exercise" or other similar arrangement approved by the
Committee. Options will have a term of not more than ten years, will become
exercisable at such times and upon such terms as the Committee may determine,
and may be exercised following termination of employment as determined by the
Committee in the document evidencing the Award.
 
  Restricted Stock is Common Stock transferred to the grantee, generally
without payment to the Company, which shares are subject to certain
restrictions and to a risk of forfeiture. A Restricted Stock Unit is a right
to receive shares of Common Stock or cash at the end of a specified period,
subject to a risk of forfeiture. The vesting of Restricted Stock and
Restricted Stock Units may be conditioned upon the satisfaction of specified
performance criteria. The maximum number of shares of Common Stock that may be
awarded as Restricted Stock under the 1998 Plan is 500,000.
 
  In the event of a "change of control" (as defined in the 1998 Plan), (i) any
Award carrying a right to exercise that was not previously exercisable and
vested will become fully exercisable and vested, (ii) the restrictions,
deferral limitations, payment conditions and forfeiture conditions applicable
to any other Award granted under the 1998 Plan will lapse and such Award will
be deemed fully vested, and (iii) any performance conditions imposed with
respect to Awards will be deemed to be fully achieved.
 
  The 1998 Plan may, at any time and from time to time, be altered, amended,
suspended, or terminated by the Board of Directors, in whole or in part,
provided that no amendment that, in the opinion of counsel, requires
stockholder approval will be effective unless such amendment has received the
requisite approval of stockholders. In addition, no amendment may be made that
adversely affects any of the rights of a grantee under any Award theretofore
granted, without such grantee's consent.
 
  Set forth below is a brief discussion of certain federal income tax
consequences relating to Awards that may be granted pursuant to the 1998 Plan.
 
  Nonqualified Stock Options. In the case of a nonqualified stock option, an
option holder generally will not be taxed upon the grant of the option.
Rather, at the time of exercise of such nonqualified stock option,
 
                                      53
<PAGE>
 
the option holder will generally recognize ordinary income for federal income
tax purposes in an amount equal to the excess of the then fair market value of
the shares purchased over the option price (the "Spread"). The Company will
generally be entitled to a tax deduction at the time and in the amount that
the holder recognizes ordinary income.
   
  Incentive Stock Options. In the case of an incentive stock option, the tax
recognition event will generally occur upon the disposition of the shares
acquired upon exercise of the incentive stock option, rather than upon the
grant of the incentive stock option or upon its exercise within the
employment-related period prescribed by the Code for this purpose ("timely
exercise"). The Spread will, however, be an item of tax adjustment for
purposes of the "alternative minimum tax" imposed by Section 55 of the Code.
If, upon disposition of the shares acquired upon exercise, the special holding
period requirements prescribed in the Code with respect to incentive stock
options have been satisfied (a "Qualifying Disposition"), any taxable income
will constitute capital gain in an amount equal to the excess of the sale
proceeds over the exercise price. The Company will not be entitled to a tax
deduction with respect to the timely exercise of an incentive stock option or
the subsequent Qualifying Disposition of shares so acquired. The tax
consequences of any untimely exercise of an incentive stock option or non-
Qualifying Disposition of acquired shares will be determined in accordance
with the rules applicable to nonqualified stock options, as described in the
preceding paragraph.     
 
  Exercise with Shares. An option holder who pays the option price upon
exercise of an option, in whole or in part, by delivering already owned shares
of stock will generally not recognize gain or loss on the shares surrendered
at the time of such delivery, except under certain circumstances. Rather,
recognition of such gain or loss will generally occur upon disposition of the
shares acquired in substitution for the shares surrendered.
 
  Restricted Stock. Generally, the grant of restricted stock has no federal
income tax consequences at the time of grant. Rather, at the time the shares
are no longer subject to a substantial risk of forfeiture (as defined in the
Code), the holder will recognize ordinary income in an amount equal to the
fair market value of such shares. A holder may, however, elect to be taxed at
the time of the grant. The Company generally will be entitled to a deduction
at the time and in the amount that the holder recognizes ordinary income.
 
  THE FOREGOING SUMMARY CONSTITUTES A BRIEF OVERVIEW OF THE PRINCIPAL FEDERAL
INCOME TAX CONSEQUENCES RELATING TO THE ABOVE-DESCRIBED AWARDS BASED UPON
CURRENT FEDERAL INCOME TAX LAWS. THIS SUMMARY IS NOT INTENDED TO BE EXHAUSTIVE
AND DOES NOT DESCRIBE STATE, LOCAL OR FOREIGN TAX CONSEQUENCES. PARTICIPANTS
IN THE 1998 PLAN SHOULD CONSULT THEIR PERSONAL TAX ADVISORS TO DETERMINE THE
SPECIFIC TAX CONSEQUENCES TO THEM OF AWARDS AND OTHER TRANSACTIONS RELATING
THERETO.
 
  KNIGHT/TRIMARK GROUP, INC. 1998 NONEMPLOYEE DIRECTOR STOCK OPTION PLAN. The
Company, with the approval of its stockholders, has adopted the 1998
Nonemployee Director Stock Option Plan (the "Nonemployee Director Plan"). The
Nonemployee Director Plan will take effect upon, and only in the event of, the
consummation of this Offering. A maximum of 264,000 shares of Common Stock
have been reserved for issuance under the Nonemployee Director Plan, subject
to equitable adjustment upon the occurrence of any increase in, decrease in or
exchange of the outstanding shares of Common Stock through merger,
consolidation, recapitalization, reclassification, stock split, stock dividend
or similar corporate transaction.
 
  Under the Nonemployee Director Plan, any questions of administration that
arise will be resolved by the Board of Directors. Approximately eight
directors will be eligible to receive awards under the Plan. All stock options
granted under the Nonemployee Director Plan ("Director Options") will be
nonqualified stock options.
 
  A Director Option to purchase 8,000 shares of Common Stock will be granted
upon the effective date of the Nonemployee Director Plan to each then
Nonemployee Director and, thereafter, to each new Nonemployee Director upon
election to the Board of Directors. In addition, on the first business day
following each annual meeting of the Company's stockholders, each continuing
Nonemployee Director will
 
                                      54
<PAGE>
 
be granted a Director Option to purchase 4,000 shares of Common Stock. The
exercise price of a Director Option will be the fair market value per share of
Common Stock on the date of grant and may be paid in cash or Common Stock or
pursuant to a "broker's cashless exercise." Director Options will have a term
of ten years, will become exercisable in four equal annual instalments
commencing with the first anniversary of the date of grant, and may be
exercised following a director's termination of service, as determined by the
Board of Directors in the document evidencing the grant.
 
  In the event of a "change of control" (as defined in the Nonemployee
Director Plan), any outstanding Director Options not yet exercisable in whole
or in part will become exercisable in full.
 
  The Nonemployee Director Plan may, at any time and from time to time, be
altered, amended, suspended, or terminated by the Board of Directors, in whole
or in part; provided that no amendment that, in the opinion of counsel,
requires stockholder approval will be effective unless such amendment has
received the requisite approval of stockholders. In addition, no amendment may
be made that adversely affects any of the rights of a grantee under any
Director Option theretofore granted, without such grantee's consent.
 
  For a discussion of certain federal income tax consequences relating to
options granted pursuant to the Nonemployee Director Plan, see "Knight/Trimark
Group, Inc. 1998 Long-Term Incentive Plan."
 
  KNIGHT/TRIMARK GROUP, INC. MANAGEMENT INCENTIVE PERFORMANCE PLAN. The
Company has established a profit-pool incentive plan (the "Incentive Plan"),
currently consisting of three sub-profit pools, one for the Company
(disregarding its subsidiary companies)(the "Holding Company Pool"), one for
Knight (the "Knight Sub-Pool") and one for Trimark (the "Trimark Sub-Pool").
The Incentive Plan also provides for the creation of a new sub-pool at the
time of any future formation or acquisition of a new Company subsidiary, to be
allocated by such person or persons as determined by a committee of the Board
of Directors consisting of its executive officers (the "Executive Board").
 
  The annual Holding Company Pool will equal 15% of the before-tax profits of
the Company (on an unconsolidated basis) earned by the Holding Company during
each fiscal quarter (not taking into account amounts paid out pursuant to the
Incentive Plan) and will be allocated on a quarterly basis by the Chief
Executive Officer of the Company. The annual Knight Sub-Pool equals 15% of the
before-tax profits earned by Knight during each fiscal quarter (not taking
into account amounts paid out pursuant to the Incentive Plan), and is
allocated on a quarterly basis by the Chief Executive Officer and Chief
Operation Officer of Knight. The annual Trimark Sub-Pool equals 15% of the
before-tax profits earned by Trimark during each fiscal quarter (not taking
into account amounts paid out pursuant to the Incentive Plan), and is
allocated on a quarterly basis by the Chief Executive Officer and Chief
Operation Officer of Trimark. Such officers may not themselves receive an
allocation from any sub-profit pool in any year unless the entire Company, on
a consolidated basis, earns a before-tax profit (not taking into account
amounts paid out pursuant to the Incentive Plan).
       
401(K) PLAN
 
  The Company has a Section 401(k) Plan (the "401(k) Plan"), a tax-qualified
plan covering substantially all of the Company's employees. Under the terms of
the 401(k) Plan, participants may elect to defer a portion of their
compensation, subject to certain limitations and the Company is required to
make annual contributions to the 401(k) Plan equal to 50% of the contributions
made by its employees, subject to certain limitations.
 
EMPLOYMENT AGREEMENTS
 
  The Company has entered into employment agreements substantially the same as
the prior LLC employment agreements with Messrs. Raquet, Steinman, Lazarowitz
and Pasternak, and the prior Trimark employment agreement with Mr. Sanfilippo
(collectively, the "Executives"). The term of each of the agreements (the
"Agreements") will be four (4) years, beginning on the date of the
consummation of the
 
                                      55
<PAGE>
 
Offering, with annual, automatic one-year extensions beginning on the fourth
anniversary of such date unless either party gives notice of nonrenewal at
least 60 days prior to such anniversary.
 
  Mr. Pasternak's Agreement provides that he will be President and Chief
Executive Officer of the Company and President and Chief Executive Officer of
Knight. Each of Messrs. Raquet and Lazarowitz's Agreement provides that the
Executive will be Executive Vice President of the Company; Mr. Raquet will
also be Chief Operating Officer of Knight and Mr. Lazarowitz will be Chief
Operating Officer of Trimark. Mr. Steinman's Agreement provides that he will
be Chairman of the Board of the Company and Chief Executive Officer of
Trimark. Mr. Sanfilippo's Agreement provides that he will be Executive Vice
President of the Company and President of Trimark. Each Executive will receive
an annual salary of $250,000, as from time to time increased by the Board of
Directors.
   
  Each Agreement provides for the payment of annual bonuses pursuant to the
Incentive Plan (see "Knight/Trimark Group, Inc. 1998 Incentive Plan,") and for
participation in current and future employee benefit plans. In addition, the
Agreements of each of Messrs. Pasternak and Sanfilippo provide for the payment
of a sales commission equal to a percentage (in the case of Mr. Pasternak,
35%; in the case of Mr. Sanfilippo, a percentage consistent with the Company's
other traders) of the net, before-tax trading profits of the Executive's
personal trading account; and the Agreements of each of Messrs. Steinman and
Lazarowitz provide for the payment of an additional annual bonus until March
31, 2000, equal in each case to 5 percent of the before-tax earnings of
Trimark (the "Additional Trimark Bonus").

                             CERTAIN TRANSACTIONS
 
THE REORGANIZATION
 
  The Company was organized in April 1998 for the purpose of succeeding to the
business of Roundtable Partners, L.L.C. (the "LLC"). Concurrent with the
closing of the Offering, based on an assumed initial public offering price of
$15.00 per share, all of the member interests of the LLC will be exchanged for
41,000,000 shares of Common Stock of the Company. Certain members of the LLC,
including management, who have so elected, will receive 1,741,581 additional
shares of Class A Common Stock valued at the initial public offering price
with respect to their share of the undistributed income of the LLC through
March 31, 1998 (the "Undistributed Profits"). Management of the Company has
elected to receive shares of Class A Common Stock for all of its Undistributed
Profits. The Company will receive no additional consideration in connection
with such conversion of member interests into shares of Common Stock. In
connection with the Reorganization, Knight will become the successor entity to
Knight Securities, L.P., and Trimark will become the successor entity to
Trimark Securities, L.P. Prior to the effective date of the Registration
Statement of which this Prospectus is a part, certain non-management members
of the LLC, who have so elected, will receive a cash distribution of all or a
portion of their Undistributed Profits. Concurrently with such distribution,
the LLC intends to make a cash distribution to each member of an estimate of
its share of the total amount of profits of the LLC accruing between April 1,
1998 and the closing of this Offering.
 
BROWN & COMPANY SECURITIES CORPORATION
 
  On April 24, 1996, the Company entered into a $500,000 subordinated note
agreement with Brown & Company Securities Corporation ("Brown"), a major
customer of the Company, which pays interest quarterly at a market rate
approximating the prevailing Federal Funds Rate. The subordinated note matures
on April 23, 1999, but may be prepaid by the Company at any time without
penalty. Concurrent with the execution of the subordinated note, the Company
granted Brown certain benefits, including the right to receive additional
payments based on the amount of order flow provided to the Company by Brown.
For the period from March 27, 1995 through December 31, 1995, the years ended
December 31, 1996 and 1997, and for the three-months ended March 31, 1998,
Brown was the source of 4.0%, 4.6%, 4.3% and 4.1%, respectively, of the
Company's order flow. Payments by the Company to Brown during these periods
amounted to $2.1 million, $6.2 million, $7.5 million and $1.7 million,
respectively. Additionally, in April 1996, the Company granted Brown the right
to purchase 7,143 Common Units in the LLC at the then prevailing market price
of $10.00 per Common Unit (the "Brown Option"). As of the date of grant, the
right to purchase the Common Units had a de minimis value. Brown has elected
to exercise the Brown Option at the closing of the Offering. Upon the closing
of the Offering, Brown will own 394,887 shares of the Company's Class A Common
Stock. The aggregate exercise price for the Brown Option is $71,430.
 
TRANSACTIONS WITH AFFILIATES
 
  Transactions with Affiliates. Immediately prior to the Reorganization, 60%
of the Common Units of the LLC will be owned by a consortium of 27 broker-
dealers or their affiliates. After the closing of this Offering, such broker-
dealer owners will own 48.5% of the Company's Common Stock (47.2% if the
Underwriters' over-allotment option is exercised in full).

                         DESCRIPTION OF CAPITAL STOCK
 
  The following summary description of the capital stock of the Company does
not purport to be complete and is subject to the provisions of the Certificate
of Incorporation and Bylaws of the Company, which are included as exhibits to
the Registration Statement of which this Prospectus forms a part, and the
provisions of applicable law.
 
AUTHORIZED AND OUTSTANDING CAPITAL STOCK
 
  Upon consummation of the Offering, the authorized Capital Stock of the
Company will consist of 220,000,000 shares of Common Stock, par value $.01 per
share, and 20,000,000 shares of Preferred Stock, par value $.01 per share (the
"Preferred Stock"). Of the 220,000,000 authorized shares of the Company's
Common Stock, 200,000,000 shares will be designated Class A Common Stock and
20,000,000 shares will be designated as Class B Common Stock. As of March 31,
1998, after giving effect to the Reorganization and the Offering, 47,484,299
shares of Class A Common Stock will be issued and outstanding and 3,945,528
shares of Class B Common Stock will be issued and outstanding.
 
COMMON STOCK
 
  Voting Rights. Except as otherwise required by law or, as described below,
by the Certificate of Incorporation, the holders of shares of Class A Common
Stock will vote together as a single class. Each share of Class A Common Stock
will entitle the registered holder thereof to one vote. There will be no
cumulative voting and, therefore, holders of a majority of the shares of Class
A Common Stock can elect all of the directors.
   
  The holders of Class A Common Stock will be entitled to elect all members of
the Company's Board of Directors and the holders of Class B Common Stock will
have no voting rights except as otherwise provided by law.     
 
  Conversion into Class A Common Stock. Pursuant to the Certificate of
Incorporation, each share of Class B Common Stock will be exchangeable at any
time upon sale or other transfer thereof, subject to certain limitations on
such sale or transfer, for one fully paid and nonassessable share of Class A
Common Stock, subject to adjustment for any stock split. Subject to certain
limitations and upon satisfaction of certain conditions, holders of Class B
Common Stock shall be entitled to convert their shares into the same number of
shares of Class A Common Stock.
 
  Liquidation. In the event of any voluntary or involuntary liquidation,
dissolution or winding up of the Company, after payment in full to creditors
and distribution in full of the preferential amounts, if any, to be
distributed to holders of shares of Preferred Stock, unless otherwise required
by law, holders of shares of Common Stock will be entitled to receive all the
remaining assets of the Company of whatever kind available for distribution to
stockholders ratably in proportion to the number of shares of Common Stock
held by them. Pursuant to the Certificate of Incorporation, the holders of
Common Stock will participate in the distribution of such assets as if all
classes and series of Common Stock constituted a single class of stock.
 
  Dividends. Subject to the preferential rights of holders of Preferred Stock,
if any, the holders of shares of Common Stock will be entitled to receive,
when, as and if declared by the Board of Directors, out of the assets of the
Company which are by law available therefor, dividends payable either in cash,
in property or in shares of capital stock. Pursuant to the Certificate of
Incorporation, no dividend will be declared or paid in respect of any class of
Common Stock by the Company unless the holders of all classes of Common Stock
receive the same per share dividend, payable in the same amount and type of
consideration, as if such classes constituted a single class, except that if
any dividend is declared that is payable in shares of Common Stock, or in
subscription or other rights to acquire shares of Common Stock, then such
dividend will be declared and paid at the same rate per share with respect to
each class of Common Stock, the dividend payable on shares of Class A Common
Stock will be payable only in shares of, or in subscription or other rights to
acquire shares of, Class A Common Stock, and the dividend payable on shares of
Class B Common Stock will be payable only in shares of, or in subscription or
other rights to acquire shares of Class B Common Stock.
 
                                      61

PREFERRED STOCK
 
  Under the Certificate of Incorporation, the Board of Directors will be
expressly authorized, without further stockholder approval, to provide for the
issuance of all or any shares of Preferred Stock in one or more classes or
series, and to fix for each such class or series such voting powers, full or
limited, or no voting powers, and such distinctive designations, preferences
and relative, participating, optional or other special rights and such
qualifications, limitations or restrictions thereof, as shall be stated and
expressed in the resolution or resolutions adopted by the Board of Directors
providing for the issuance of such class or series and as may be permitted by
the DGCL. The Company has no present plans to issue any shares of Preferred
Stock. See "--Antitakeover Effects of Provisions of the Certificate of
Incorporation and Bylaws and the DGCL."
 
REGISTRATION RIGHTS
 
  Certain securityholders of the Company (the "Rightsholders") are entitled to
require the Company to register under the Securities Act, up to a total of
      shares (the "Registrable Shares") of outstanding Common Stock (including
      Registrable Shares being sold by the Selling Stockholder in this
offering) pursuant to the terms of a Registration Rights Agreement (the
"Registration Rights Agreement"). The Registration Rights Agreement provides
that in the event the Company proposes to register any of its securities under
the Securities Act at any time or times, the Rightsholders, subject to certain
exceptions, shall be entitled to include Registrable Shares in such
registration. However, the managing underwriter of any such offering may
exclude for marketing reasons some of such Registrable Shares from such
registration. In addition, certain Rightsholders have additional rights,
subject to certain conditions and limitations, to require the Company to
prepare and file a registration statement under the Securities Act with
respect to their Registrable Shares. The Company is generally required to bear
the expenses of all such registrations, except underwriting discounts and
commissions.
 
ANTITAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION AND
BYLAWS AND THE DGCL
 
  Certificate of Incorporation and Bylaws. The Certificate of Incorporation
will provide that stockholders are not entitled to call a special meeting of
stockholders, nor to require the Board of Directors to call such a meeting.
The Certificate of Incorporation will provide that stockholders will not be
entitled to act by written consent in lieu of a meeting except where such
consent is unanimous. These provisions of the Certificate of Incorporation,
could discourage potential acquisition proposals and could delay or prevent a
change of control of the Company.
 
  Delaware Takeover Statute. The Company is subject to Section 203 of the DGCL
("Section 203"), which, subject to certain exceptions, prohibits a publicly
held Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years following the date that
such stockholder became an interested stockholder, unless: (i) prior to such
date, the board of directors of the corporation approved either the business
combination or the transaction that resulted in the stockholder becoming an
interested stockholder; (ii) upon consummation of the transaction that
resulted in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned (a) by persons
who are directors and also officers and (b) by employee stock plans in which
employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or
exchange offer; or (iii) on or subsequent to such date, the business
combination is approved by the board of directors and authorized at an annual
or special meeting of stockholders, and not by written consent, by the
affirmative vote of at least 66 2/3% of the outstanding voting stock that is
not owned by the interested stockholder.
 
  Section 203 defines "business combination" to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii)
any sale, transfer, pledge or other disposition of 10% or more of the assets
of the corporation involving the interested stockholder; (iii) subject to
certain exceptions, any
 
                                      62
<PAGE>
 
transaction that results in the issuance or transfer by the corporation of any
stock of the corporation to the interested stockholder; (iv) any transaction
involving the corporation that has the effect of increasing the proportionate
share of the stock of any class or series of the corporation beneficially
owned by the interested stockholder; or (v) the receipt by the interested
stockholder of the benefit of any loans, advances, guarantees, pledges or
other financial benefits provided by or through the corporation. In general,
Section 203 defined an interested stockholder as any entity or person
beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.
 
  Other Provisions. The holders of Common Stock are not entitled to preemptive
or subscription rights. In any merger, consolidation or business combination,
the consideration to be received per share by holders of Class A Common Stock
is identical to that to be received by holders of Class B Common Stock. No
class of Common Stock may be subdivided, consolidated, reclassified or
otherwise changed unless the other class of Common Stock concurrently is
subdivided, consolidated, reclassified or otherwise changed in the same
proportion and in the same manner. All outstanding shares are, and the shares
of Class A Common Stock offered hereby will be upon issuance, validly issued,
fully paid and nonassessable.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, the Company will have an aggregate of
51,429,827 shares of Common Stock outstanding (assuming no exercise of the
Underwriters' over-allotment option). Of these shares, the 10,000,000 shares
of Class A Common Stock sold in this Offering will be freely tradable without
restriction or further registration under the Securities Act, except that any
shares purchased by an "affiliate" of the Company, as that term is defined in
Rule 144 ("Rule 144") under the Securities Act (an "Affiliate"), may generally
be sold only in compliance with Rule 144 as described below.
 
  In addition, the existing stockholders have the right to cause the Company
to register the sale of certain shares of Class A Common Stock or Class B
Common Stock owned by them and/or to include their shares in future
registrable statements relating to the Company's securities.
 
  Approximately 41,429,827 of the outstanding shares of Common Stock are
"restricted securities" as that term is defined under Rule 144 (the
"Restricted Shares"). Of these Restricted Shares,     shares will be subject
to lock-up agreements as described below. Upon expiration of these agreements
all of the Restricted Shares will be available for sale in the public market,
subject to the provisions of Rule 144 under the Securities Act. Upon
completion of this offering, the holders of 41,429,827 of the Restricted
Shares will be entitled to registration rights. Sales of Restricted Shares in
the public market, or the availability of such shares for sale, could
adversely affect the market price of the Common Stock. See "Description of
Capital Stock--Registration Rights."
 
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including an Affiliate, who has beneficially
owned Restricted Shares for at least one year is entitled to sell, within any
three-month period, a number of such shares that does not exceed the greater
of (i) one percent of the then outstanding shares of Class A Common Stock
(approximately 474,844 shares immediately after this offering) or (ii) the
average weekly trading volume in the Class A Common Stock in the Nasdaq
National Market during the four calendar weeks preceding the date on which
notice of such sale is filed with the Securities and Exchange Commission. Such
sales under Rule 144 are also subject to certain manner of sale provisions and
notice requirements and to the availability of current public information
about the Company. In addition, a person who is not an Affiliate and has not
been an Affiliate for at least three months prior to the sale and who has
beneficially owned Restricted Shares for at least two years may resell such
shares without regard to the requirements described above. The Company is
unable to estimate accurately the number of Restricted Shares that ultimately
will be sold under Rule 144 because the number of shares will depend in part
on the market price for the Common Stock, the personal circumstances of the
sellers and other factors. See "Risk Factors--Shares Eligible for Future Sale"
and "Risk Factors--No Prior Market; Possible Volatility of Stock Price."
 
  After the date of this Prospectus, the Company intends to file a
registration statement under the Securities Act on Form S-8 to register all
shares of Common Stock issuable pursuant to the Company's stock option plans.
Such registration statement is expected to become effective immediately upon
filing. Accordingly, shares issued under the Company's stock plans will be
eligible for sale in the public markets upon vesting and exercise of options
or awards, subject to the Rule 144 volume restrictions applicable to
affiliates and, in certain cases, lock-up agreements.
 
  All executive officers and directors of the Company and substantially all of
the Company's stockholders (including the Selling Stockholder), who upon the
completion of this Offering will hold in the aggregate     shares of Common
Stock, have agreed that they will not, without the prior written consent of
BancAmerica Robertson Stephens, directly or indirectly, offer to sell, sell,
contract to sell or otherwise dispose of any shares of Common Stock
beneficially owned by them for a period of 180 days after the date of this
Prospectus, subject to certain exceptions. BancAmerica Robertson Stephens may,
in its sole discretion and at any time, without notice, release all or any
portion of the securities subject to lock-up agreements. See "Underwriting."

  The Company is unable to estimate the number of shares that will be sold
under Rule 144, as this will depend upon the market price for the Common Stock
of the Company, the personal circumstances of the sellers and other factors.
Prior to this offering, there has been no public market for the Common Stock,
and there can be no assurance that a significant public market for the Common
Stock will develop or be sustained after the Offering.
 
  Sales of substantial amounts of Common Stock, or the perception that such
sales could occur, could adversely affect prevailing market prices for the
Common Stock and could impair the Company's future ability to obtain capital
through an offering of equity securities.

  The Representatives have advised the Company and the Selling Stockholder
that the Underwriters propose to offer the shares of Class A Common Stock to
the public at the initial public offering price set forth on the cover page of
this Prospectus and to certain dealers at such price less a concession not in
excess of $    per share, of which $    may be reallowed to other dealers.
After the completion of the initial public offering, the public offering
price, concession and reallowance to dealers may be reduced by the
Representatives. No such reduction shall change the amount of proceeds to be
received by the Company and the Selling Stockholder as set forth on the cover
page of this Prospectus.
 
  The Company has granted to the Underwriters an option, exercisable during
the 30-day period after the date of this Prospectus, to purchase up to
1,500,000 additional shares of Class A Common Stock from the Company at the
initial public offering price per share set forth on the cover page of this
Prospectus. To the extent that the Underwriters exercise such option, each of
the Underwriters will have a firm commitment to purchase approximately the
same percentage of such additional shares that the number of shares of Class A
Common Stock to be purchased by it shown in the above table represents as a
percentage of the total number of shares offered hereby. If purchased, such
additional shares will be sold by the Underwriters on the same terms less the
underwriting discount as those on which the shares offered hereby are being
sold.
 
  The Underwriting Agreement contains covenants of indemnity among the
Underwriters, the Selling Stockholder and the Company against certain civil
liabilities, including liabilities under the Securities Act and liabilities
arising from breaches of representations and warranties contained in the
Underwriting Agreement.
 
  Pursuant to the terms of lock-up agreements, the holders of 41,429,827
shares of the Company's Common Stock have agreed, for a period of up to 180
days after the date of this Prospectus, that, subject to certain exceptions,
they will not contract to sell or otherwise dispose of any shares of Common
Stock, any options or warrants to purchase shares of Common Stock or any
securities convertible into, or exchangeable for, shares of Common Stock,
owned directly by such holders or with respect to which they have the power of
disposition, without the prior written consent of BancAmerica Robertson
Stephens. BancAmerica Robertson Stephens may, in its sole discretion, and at
any time without notice, release all or any portion of the securities subject
to lock-up agreements. All of the shares of Common Stock subject to lock-up
agreements may be eligible for sale in the public market upon the expiration
of the lock-up agreements, subject to Rule 144.
 
  In addition, the Company and the Selling Stockholder have agreed that until
180 days after the date of this Prospectus, the Company and the Selling
Stockholder will not, without prior written consent of BancAmerica Robertson
Stephens, subject to certain exceptions, offer, sell, contract to sell or
otherwise
 
                                      66

dispose of any shares of Common Stock, any options or warrants to purchase any
shares of Common Stock or any securities convertible into, exercisable for or
exchangeable for shares of Common Stock other than the Company's and the
Selling Stockholder's sale of shares in this offering, the issuance of shares
of Common Stock upon the exercise of outstanding options and warrants and the
grant of options to purchase shares of Common Stock under existing employee
stock option or stock purchase plans. Furthermore, the Company has agreed not
to file any registration statements on Form S-8 to register the 7,409,000
shares of Class A Common Stock reserved for issuance pursuant to its Stock
Option Plans until at least 90 days after the date of this Prospectus. See
"Management--Stock Options Plans" and "Shares Eligible for Future Sale."
 
  The Underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.
 
  The Company's subsidiary, Knight, is a party to a clearing contract with an
affiliate of PaineWebber Incorporated, whereby such affiliate clears all of
Knight's trades for usual and customary fees. One of the Underwriters,
Southwest Securities, Inc., is a stockholder of the Company. See "Certain
Transactions."
 
  Prior to this offering, there has been no public market for the Class A
Common Stock of the Company. Consequently, the initial public offering price
for the Class A Common Stock offered hereby will be determined through
negotiations between the Company and the Representatives. Among the factors to
be considered in such negotiations are prevailing market conditions, certain
financial information of the Company, market valuations of other companies
that the Company and the Representatives believe to be comparable to the
Company, estimates of the business potential of the Company, the present state
of the Company's development and other factors deemed relevant.
 
  The offering is being conducted in accordance with Rule 2720 ("Rule 2720")
of the National Association of Securities Dealers, Inc. (the "NASD") which
provides that, among other things, when an NASD member firm participates in
the offering of equity securities of a company with whom such member has a
"conflict of interest" (as defined in Rule 2720), the initial public offering
price can be no higher than that recommended by a "qualified independent
underwriter" (as defined in Rule 2720) (a "QIU"). BancAmerica Robertson
Stephens is serving as the QIU in the offering and will recommend a price in
compliance with the requirements of Rule 2720. BancAmerica Robertson Stephens
has performed due diligence investigations and reviewed and participated in
the preparation of this Prospectus and the Registration Statement of which
this Prospectus forms a part. BancAmerica Robertson Stephens, in its capacity
as QIU, will receive no additional compensation as such in connection with the
offering.
 
  The Representatives have advised the Company that, pursuant to Regulation M
under the Securities Act, certain persons participating in the offering may
engage in transactions, including stabilizing bids, syndicate covering
transactions, or the imposition of penalty bids which may have the effect of
stabilizing or maintaining the market price of the Class A Common Stock at a
level above that which might otherwise prevail in the open market. A
"stabilizing bid" is a bid for or the purchase of the Class A Common Stock on
behalf of the Underwriters for the purpose of fixing or maintaining the price
of the Class A Common Stock. A "syndicate covering transaction" is the bid for
or the purchase of the Class A Common Stock on behalf of the Underwriters to
reduce a short position incurred by the Underwriters in connection with the
offering. A "penalty bid" is an arrangement permitting the Representatives to
reclaim the selling concession otherwise accruing to an Underwriter or
syndicate member in connection with this offering if the shares of Class A
Common Stock originally sold by such Underwriter or syndicate member are
purchased by the Representatives in a syndicate covering transaction and has
therefore not been effectively placed by such Underwriter or syndicate member.
The Representatives have advised the Company that such transactions may be
effected in NASDAQ as a National Market issue or otherwise and, if commenced,
may be discontinued at any time.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Advisory Board and
Members of Roundtable Partners, L.L.C.
 
  In our opinion, the accompanying consolidated statements of financial
condition and the related consolidated statements of income, changes in
members' equity and cash flows present fairly, in all material respects, the
consolidated financial position of Roundtable Partners, L.L.C. and its
subsidiaries at December 31, 1996 and 1997, and the results of their
operations and their cash flows for the period from March 27, 1995 (date of
initial capitalization) through December 31, 1995 and for the years ended
December 31, 1996 and 1997, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with generally accepted auditing standards which require that we
plan and perform the audits to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for the opinion expressed above.

 (INFORMATION AT MARCH 31, 1998 AND FOR THE THREE MONTHS ENDED MARCH 31, 1997
                            AND 1998 IS UNAUDITED)
 
1. ORGANIZATION AND DESCRIPTION OF THE BUSINESS
 
  Roundtable Partners, L.L.C. ("Roundtable"), a Delaware limited liability
corporation, was initially capitalized on March 27, 1995 to own and operate
the securities market-making businesses of Knight Securities, L.P. ("Knight")
and Trimark Securities, L.P. ("Trimark") (collectively, the "Company"). The
Company is owned 20% by key employees of Knight, 20% by key employees of
Trimark (collectively, the "Management Investors") and 60% by a consortium of
independent securities firms and investors (the "Non-Management Investors").
As a limited liability company, the Company has a finite life and must be
dissolved no later than September 30, 2024.
 
  The Company, which operates in one segment and line of business - equity
securities market-making, owns a 99.99% general partnership interest in both
Knight and Trimark. A subchapter S holding corporation owned by the Management
Investors owns a 0.01% limited partnership interest in each entity. Knight, a
New York limited partnership, was organized on February 17, 1995 by Roundtable
to operate as a market maker in over-the-counter equity securities ("OTC
stocks"), principally securities traded on the National Association of
Securities Dealers, Inc.'s ("NASD") Automated Quotation System ("NASDAQ"),
including Small Capitalization listings and securities listed on the OTC
Bulletin Board. Trimark is a New York Limited Partnership which was acquired
by the Company on March 27, 1995 (Note 2). Trimark operates as a market-maker
in equity securities listed on the New York and American Stock Exchanges
("listed stocks"). Knight and Trimark are registered as broker-dealers with
the Securities and Exchange Commission and are members of the NASD.
 
2. ACQUISITIONS
 
  On March 27, 1995, Trimark Securities, Inc., an unaffiliated securities
firm, contributed its market-making business in listed stocks and the fixed
assets necessary to operate such business to Trimark Securities L.P. for a
99.99% general partnership interest. Immediately thereafter, Trimark
Securities, Inc. sold its 99.99% general partnership interest in Trimark
Securities, L.P. to the Company in exchange for 1.5 million Preferred B Units
of the Company with a fair value of $15 million and contingent consideration.
In connection with that transaction, the Company incurred $348,000 in
acquisition costs. The Company's acquisition of the 99.99% general partnership
interest in Trimark Securities L.P. was recorded under the purchase method and
the carrying values of the assets and liabilities acquired were adjusted to
their fair market values as of the acquisition date. The excess of the
purchase price over the fair value of the net assets acquired of $13,960,195
was recorded as goodwill and is being amortized over a period of ten years.
 
  In connection with the acquisition, the Company entered into an agreement
which entitles Trimark Securities, Inc. to receive additional consideration
during the five years immediately subsequent to the acquisition, equal to 10%
of Trimark's pre-tax earnings, before amortization of goodwill and
depreciation on fixed assets initially purchased. The additional consideration
represents contingent consideration to be paid in connection with the Trimark
acquisition. All amounts paid under this arrangement are being capitalized as
additional purchase price (goodwill) and amortized over the remainder of the
original ten year amortization period.
 
  Pursuant to an agreement effective November 17, 1997, Trimark purchased the
business and the related fixed assets of Tradetech Securities, L.P.
("Tradetech"), an Illinois Limited Partnership, in exchange for $750,000 in
cash and contingent consideration. Tradetech was a direct competitor of
Trimark operating as a market-maker in listed stocks and, after the
acquisition, its business and operations were integrated into Trimark's. The
acquisition was accounted for under the purchase method and the carrying
values of the assets acquired were adjusted to their fair market values as of
the acquisition date. The excess of the purchase price over the fair value of
the assets acquired of $400,000 was recorded as goodwill and is being
amortized over a period of five years.

  In connection with the acquisition, Trimark entered into an agreement with
Tradetech which entitles Tradetech to additional consideration equal to 10% of
Trimark's pretax earnings during the period from the acquisition date through
December 31, 2000 (the "Earnout Period"). If, after the Earnout Period, the
owners of Tradetech have not received payments which total $3,000,000, the
additional consideration shall continue until the earlier of (i) December 31,
2002, or (ii) an aggregate of $3,000,000 has been paid. All amounts paid under
this arrangement will be capitalized as additional purchase price (goodwill)
and amortized over the remainder of the original five year amortization
period.
 
  The total contingent consideration paid and recorded as goodwill by the
Company was as follows:

3. SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of consolidation and form of presentation
 
  The accompanying consolidated financial statements include the accounts of
Roundtable, Knight and Trimark. All significant intercompany transactions and
balances have been eliminated.
 
 Cash equivalents
 
  Cash equivalents represent money market accounts, which are payable on
demand. The carrying amount of such cash equivalents approximates fair value
due to the short-term nature of these instruments.
 
 Trading activities
 
  Securities owned and securities sold, not yet purchased, which primarily
consist of listed and OTC stocks, are carried at market value and are recorded
on a trade date basis. Net trading revenue (trading gains, net of trading
losses) and related expenses, including compensation and benefits, execution
and clearance fees and payments for order flow, are also recorded on a trade
date basis. Payments for order flow represent payments to other broker-dealers
for directing their order executions to Knight and Trimark.
 
 Mandatorily redeemable preferred units
 
  The Company's Preferred A and Preferred B Units are mandatorily redeemable,
and have been classified as liabilities in the Consolidated Statements of
Financial Condition, and the related distributions on such units have been
classified as interest expense in the Consolidated Statements of Income.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 (INFORMATION AT MARCH 31, 1998 AND FOR THE THREE MONTHS ENDED MARCH 31, 1997
                            AND 1998 IS UNAUDITED)
 
 
 Depreciation, amortization and occupancy
 
  Fixed assets are being depreciated on a straight-line basis over their
estimated useful lives of three to seven years. Leasehold improvements are
being amortized on a straight-line basis over the life of the related office
lease. The Company records rent expense on a straight-line basis over the life
of the lease.
 
 Income taxes
 
  As a limited liability company, the Company is treated as a partnership and,
as such, is not subject to federal, state or local income taxes.
 
 Estimated fair value of financial instruments
 
  Statement of Financial Accounting Standards No. 107, "Disclosure about Fair
Value of Financial Instruments," requires the disclosure of the fair value of
financial instruments, including assets and liabilities recognized on the
Consolidated Statements of Financial Condition. The Company's securities owned
and securities sold, not yet purchased are carried at market value. Management
estimates that the fair values of other financial instruments recognized on
the Consolidated Statements of Financial Condition (including receivables,
payables, accrued expenses, subordinated debt and mandatorily redeemable
preferred units) approximates their carrying value, as such financial
instruments are short-term in nature, bear interest at current market rates or
are subject to frequent repricing.
 
 Other
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 Unaudited interim information
 
  The interim financial statements and related financial information as of
March 31, 1998 and for the three months ended March 31, 1998 and March 31,
1997 are unaudited; however, in the opinion of the Company, the interim
information includes all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of the results of operations
for the interim periods. The results of operations for the three months ended
March 31, 1998 are not necessarily indicative of the results to be expected
for the full year.

5. SUBORDINATED NOTES
 
  On March 24, 1995, the Company entered into a $5,000,000 subordinated note
agreement with Waterhouse Securities, Inc. ("Waterhouse"), a major customer,
which paid interest quarterly at a market rate based on the broker call rate
and matured on March 23, 1997. The subordinated note was senior in liquidation
to the Common Units and Mandatorily Redeemable Preferred A and B Units, but
was subordinate to the claims of all other creditors. Concurrent with the
execution of the subordinated note, the Company granted Waterhouse certain
benefits accorded to holders of Common Units, including the right to receive
additional payments based on the amount of order flow provided by Waterhouse.
Effective January 1, 1996, Waterhouse entered into an agreement with the
Company to exchange the subordinated note for 71,429 Common Units and 428,571
Preferred A Units issued by the Company with an aggregate value of $5,000,000.
As a result of the exchange, the subordinated note was satisfied in full and
canceled. The Common Units owned by Waterhouse are non-voting. In connection
with the issuance of Common Units to Waterhouse, the Management Investors
purchased, in aggregate, 47,620 additional Common Units at a price of $10 per
unit, such that, after the aforementioned transactions, the Management
Investors and the Non-Management Investors owned 40% and 60%, respectively, of
the total outstanding Common Units.
 
  On April 24, 1996, the Company entered into a $500,000 subordinated note
agreement with Brown & Co. Securities Corporation ("Brown"), a major customer,
which pays interest quarterly at a market rate approximating the prevailing
Federal Funds Rate. The subordinated note matures on April 23, 1999, but may
be prepaid by the Company at any time, without penalty. The subordinated note
is senior in liquidation to the Common Units and Mandatorily Redeemable
Preferred A and B Units, but is subordinate to the claims of all other
creditors. Concurrent with the execution of the subordinated note, the Company
granted Brown certain benefits accorded to holders of Common Units, including
the right to receive additional payments based on

the amount of order flow provided by Brown. Additionally, the Company granted
Brown the option to purchase 7,143 Common Units at the then prevailing market
price of $10 per Common Unit during the term that the subordinated note
remains outstanding (the "Brown Option"). As of April 24, 1996, the date of
grant, the Brown Option had a de minimis value.
 
  During 1995, the Company made additional payments for order flow totaling
$996,786 to Waterhouse. Similarly, the Company made additional payments for
order flow to Brown totaling $1,088,924, $1,865,222 and $520,360 (unaudited)
during the years ended December 31, 1996 and 1997 and during the three month
period ended March 31, 1998 (unaudited). Such amounts have been included in
payments for order flow expense in the accompanying Consolidated Statements of
Income.
 
6. MEMBERS' EQUITY
 
  The Company's Common Units, which have one for one voting rights (except for
the units owned by Waterhouse (Note 5)), are owned 40% by Management Investors
and 60% by Non-Management Investors. The Company's net income (after
distributions to holders of Preferred A and B Units) is allocated to holders
of Common Units based upon a formula which considers the volume of order flow
such holders have provided to Knight and Trimark during each period and each
holder's proportionate share of total Common Units. Net losses are shared
ratably in proportion to each member's ownership percentage. On December 31,
1997, the Company declared a distribution to holders of Common Units of
$8,405,326, which was paid on January 23, 1998. On March 31, 1998, the Company
declared a distribution to holders of Common Units of $8,767,185 (unaudited),
payable on April 20, 1998 (unaudited).
 
  The Common Units are generally not transferable, although a member may
resign from the Company at any time by providing written notice to the
Company. The Company shall pay the resigning member $10 for each Common Unit
and Preferred A Unit owned by the resigning member, and any remaining
undistributed income in the resigning member's capital account as of the date
of the written notice (the "Resigning Member Capital Distribution"). During
1997, one member resigned from the Company and received a Resigning Member
Capital Distribution of $422,463, or $10 per unit. There were no resignations
in 1995, 1996 or the three month period ended March 31, 1998 (unaudited).
 
7. MANDATORILY REDEEMABLE PREFERRED UNITS
 
  The Mandatorily Redeemable Preferred A Units ("Preferred A Units"), which
are owned by the Non-Management Investors, are non-voting and have preference
to all other units in the event of liquidation. The Preferred A Units were
originally issued to the Non-Management Investors for a price of $10 per unit,
simultaneously with the purchase of Common Units, at a ratio of six Preferred
A Units to one Common Unit. The Preferred A Units pay quarterly distributions
at a rate approximating the Federal Funds rate and are subject to mandatory
redemption annually, on April 15th, at a fixed price of $10 per unit, in an
aggregate amount equal to at least 25 percent of the Company's consolidated
net income on an annual basis. Any units not redeemed by the fifth anniversary
of the issuance date are convertible into Common Units on a one-for-one basis,
at the holder's option. There were 2,700,000 Preferred A Units authorized as
of December 31, 1995, 1996 and 1997 and March 31, 1998 (unaudited).
Distributions to holders of Preferred A Units for the period ending December
31, 1995 amounted to $590,903, which included distributions accrued, but not
paid, of $202,891 at December 31, 1995. Distributions to holders of Preferred
A Units for the year ending December 31, 1996 amounted to $1,155,859, which
included distributions accrued, but not paid, of $359,429 at December 31,
1996. Distributions to holders of Preferred A Units for the year ended
December 31, 1997 amounted to $985,737, which included distributions accrued,
but not paid, of $193,035 at December 31, 1997.

  The Mandatorily Redeemable Preferred B Units ("Preferred B Units"), which
are held by Trimark Securities, Inc., are non-voting and have preference only
to the Common Units in liquidation. The Preferred B Units pay quarterly
distributions at a rate approximating the Federal Funds rate and, after the
redemption of all Preferred A Units, are subject to mandatory redemption
annually, on April 15th, at a fixed price of $10 per unit, in an aggregate
amount equal to at least 25 percent of the Company's consolidated net income
on an annual basis, if certain levels of earnings are achieved in the prior
year. The Preferred B Units are not convertible into Common Units. There were
1,500,000 Preferred B Units authorized as of December 31, 1995, 1996 and 1997
and March 31, 1998 (unaudited). Distributions to holders of Preferred B Units
for the period ending December 31, 1995 amounted to $718,673, which includes
distributions accrued, but not paid, of $230,549 at December 31, 1995.
Distributions to holders of Preferred B Units for the year ending December 31,
1996 amounted to $936,734, which includes distributions accrued, but not paid,
of $237,449 at December 31, 1996. Distributions to holders of Preferred B
Units for the year ended December 31, 1997 amounted to $955,235, which
includes distributions accrued, but not paid, of $231,946 at December 31,
1997. No Preferred B Units were redeemed during the period from March 27, 1995
through December 31, 1995 or the years ending December 31, 1996 or 1997 or the
three months ended March 31, 1998 (unaudited). The following table presents
activity for Preferred A Units and Preferred B Units for the period from March

  As of December 31, 1997 and March 31, 1998 (unaudited), the Company had
deposited an irrevocable letter of credit which was collateralized by U.S.
Treasury securities with market values of $1,541,038 and $1,533,788
(unaudited), respectively, as security for one of its operating leases.
 
  Securities sold, not yet purchased represent obligations of Knight and
Trimark to purchase such securities at a future date. The Company may incur a
loss if the market value of the securities subsequently increases.
 
10. EARNINGS PER COMMON UNIT
 
  Basic and diluted earnings per common unit ("EPS") have been calculated by
dividing earnings applicable to common units (net income) by the weighted
average common units outstanding during each respective period. Diluted
earnings per common unit also includes the potential dilutive effects of the
Preferred A Units, under the "if-converted" method, which are convertible into
Common Units on a one-for-one basis at the holder's option if outstanding five
years from the date of issuance. In determining diluted EPS, the interest
expense applicable to the Preferred A Units during each respective period has
been added back to net income. Under the "treasury stock" method applicable to
outstanding written call options, the Brown Option did not have a dilutive
effect. The following is a reconciliation of the numerators and denominators
of the basic and diluted earnings per common unit computations:

12. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK AND CONCENTRATIONS OF
CREDIT RISK
 
  As a market maker of OTC and listed stocks, the majority of the Company's
securities transactions are conducted as principal with broker-dealer
counterparties located in the United States. The Company clears all of its
securities transactions through affiliated clearing brokers on a fully
disclosed basis (see Note 8). Pursuant to the terms of the agreement between
the Company and the clearing brokers, the clearing brokers have the right to
charge the Company for losses that result from a counterparty's failure to
fulfill its contractual obligations. The Company's policy is to monitor the
credit standing of the clearing brokers and all counterparties with which it
conducts business. As of December 31, 1997 and March 31, 1998, the Company's
credit exposures were concentrated with the clearing brokers and amounted to
$30.2 million and $78.1 million (unaudited), respectively. Additionally, as of
December 31, 1997 and March 31, 1998, the clearing brokers held, as custodian,
securities owned by the Company with a market value of $61.7 million and $63.5
million (unaudited), respectively.
 
  The net receivable or (payable) for securities transactions that have not
reached their contractual settlement date amounted to ($6,196,423),
($10,407,524), ($5,126,772) and $17,504,744 (unaudited) at December 31, 1995,
1996, 1997 and March 31, 1998 (unaudited), respectively. Such amounts were
included within receivable from clearing brokers on the Consolidated
Statements of Financial Condition.
 
13. NET CAPITAL REQUIREMENTS
 
  As registered broker-dealers and NASD member firms, Trimark and Knight are
subject to the Securities and Exchange Commission's Uniform Net Capital Rule
(the "Rule") which requires the maintenance of minimum net capital. Trimark
and Knight have elected to use the basic method, permitted by the Rule, which
requires that they each maintain net capital equal to the greater of
$1,000,000 or 6 2/3% of aggregate indebtedness, as defined.

16. PROPOSED REORGANIZATION OF THE COMPANY (UNAUDITED)
 
  The Knight/Trimark Group, Inc. (the "Corporation") was organized in April
1998 for the purpose of succeeding to the business of Roundtable Partners,
L.L.C. (the "Company"). Concurrent with the closing of the Offering, based on
an assumed initial public offering price of $15.00 per share, all of the
member interests of the Company will be exchanged for 41,000,000 shares of
Common Stock of the Company. Certain members, who have so elected, will
receive 1,741,581 additional shares of Class A Common Stock valued at the
initial public offering price with respect to their share of the undistributed
income of the Company through March 31, 1998 (the "Undistributed Profits").
Management of the Company has elected to receive shares of Class A Common
Stock for all of its Undistributed Profits. The Company will receive no
additional consideration in connection with such conversion of member
interests into shares of Common Stock. In connection with the exchange, Knight
Securities, Inc., a newly formed corporation, will become the successor entity
to Knight Securities, L.P., and Trimark Securities, Inc., a newly formed
corporation, will become the successor entity to Trimark Securities, L.P. (the
foregoing transactions, collectively, shall be referred to herein as the
"Reorganization"). Prior to the effective date of the Registration Statement
relating to the Initial Public Offering (the "Offering"), certain members of
the Company, who have so elected, will receive a cash distribution of all or a
portion of their Undistributed Profits. Concurrently with such distribution,
the Company intends to make a cash distribution to each member of an estimate
of its share of the total amount of profits of the Company accruing between
April 1, 1998 and the closing of this Offering.
 
  The Pro Forma Consolidated Statement of Financial Condition as of March 31,
1998 has been presented to give effect to the Reorganization as if it had
occurred as of the close of business on March 31, 1998. In addition, the Pro
Forma Consolidated Statement of Financial Condition gives effect to the
declaration of redemption of the Preferred A and B Units described in Note 15
as of March 31, 1998. The specific pro forma transactions are as follows:
 
 .  Exchange of 734,497 Common Units of the Company for 37,054,472 shares of
   Class A Common Stock, par value $0.01, of the Corporation ("Class A Stock")
   and 3,945,528 shares of Class B Common Stock, par value $0.01, of the
   Corporation;
 
 .  Purchase of 1,741,581 shares of Class A Stock by members of the Company for
   $26,123,719 from Undistributed Income of the Company;
 
 .  Declaration of cash distribution on Common Units payable to members of
   $26,521,293 from Undistributed Income of the Company;
 
 .  Declaration of redemption of 1,248,361 Preferred A Units for $12,483,610;
   and
 
 .  Declaration of redemption of 115,290 Preferred B Units for $1,152,900.
 
  Additionally, Brown has agreed with the Company that it will exercise its
option to purchase 7,143 Common Units of the Company by purchasing the
equivalent shares of Class A Stock of the Corporation at the closing of the
Offering.
 
  The Corporation contemplates that the Offering will comprise up to
10,000,000 shares of Class A Stock (not including an underwriters' over-
allotment option of shares) comprised of 8,688,246 newly-issued shares

and 1,311,754 shares from Selling Shareholders. The Pro Forma Consolidated
Statement of Financial Condition as of March 31, 1998 does not reflect any
adjustments related to the Offering.
 
  Prior to the Reorganization, the Company was a limited liability company and
was not subject to federal or state income taxes. Subsequent to the
Reorganization, the Corporation will be subject to federal income taxes and
state income taxes in New York, New Jersey and other states. The following pro
forma condensed consolidated statements of income give effect to the
Reorganization as if it had occurred on January 1, 1997. Pro forma income tax
expense includes pro forma amounts relating to federal income taxes, as well
as pro forma amounts relating to state income taxes in New York, New Jersey
and other states. The Company's pro forma effective tax rate of 43% differs
from the federal statutory rate of 35% primarily due to state income taxes
(6%), as well as nondeductible expenses, including the amortization of
goodwill and a portion of business development expenses (2%).

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  The Company, a Delaware corporation, is empowered by Section 145 of the
Delaware General Corporation Law (the "DGCL"), subject to the procedures and
limitations stated therein, to indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding by reason of the fact that such person is or was a
director, officer, employee or agent of the Company, or is or was serving at
the request of the Company as a director, officer, employee or agent of
another corporation or other enterprise, against reasonable expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually incurred by him in connection with such action, suit or proceeding,
if such director, officer, employee or agent acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The Company is required
by Section 145 to indemnify any person against reasonable expenses (including
attorneys' fees) actually incurred by him in connection with an action, suit
or proceeding in which he is a party because he is or was a director, officer,
employee or agent of the Company or is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation or
other enterprise, if he has been successful, on the merits or otherwise, in
the defense of the action, suit or proceeding. Section 145 also allows a
corporation to purchase and maintain insurance on behalf of any such person
against any liability asserted against him in any such capacity, or arising
out of his status as such, whether or not the corporation would have the power
to indemnify him against such liability under the provisions of Section 145.
In addition, Section 145 provides that indemnification pursuant to its
provisions is not exclusive of other rights of indemnification to which a
person may be entitled under any bylaw, agreement, vote of shareholders or
disinterested directors, or otherwise.
 
  Article 7 of the Company's Certificate of Incorporation (the "Charter")
provides that the Company shall indemnify and hold harmless any person who
was, is, or is threatened to be made a party to a proceeding by reason of the
fact that he or she (i) is or was a director or officer of the Company or (ii)
while a director or officer of the Company, is or was serving at the request
of the Company as a director, officer, partner, venturer, proprietor, trustee,
employee, agent, or similar functionary of another foreign or domestic
corporation, partnership, joint venture, sole proprietorship, trust, employee
benefit plan, or other enterprise, to the fullest extent permitted under the
DGCL. The right to indemnification under Article 7 of the Charter is a
contract right which includes, with respect to directors and officers, the
right to be paid by the Company the expenses incurred in defending any such
proceeding in advance of its disposition.

ITEM 17. UNDERTAKINGS
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  The undersigned Registrant hereby undertakes to provide to the underwriters
at the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.

          I.  The Company represents and warrants to and agrees with each
Underwriter and the Selling Stockholder that:

                (a) A registration statement on Form S-1 (File No. 333-_____)
with respect to the Shares, including a prospectus subject to completion, has
been prepared by the Company in conformity with the requirements of the
Securities Act of 1933, as amended (the "Act"), and the applicable rules and
regulations (the "Rules and Regulations") of the Securities and Exchange
Commission (the "Commission") under the Act and has been filed with the
Commission; such amendments to such registration statement, such amended
prospectuses subject to completion and such abbreviated registration statements
pursuant to Rule 462(b) of the Rules and Regulations as may have been required
prior to the date hereof have been similarly prepared and filed with the
Commission; and the Company will file such additional amendments to such
registration statement, such amended prospectuses subject to completion and such
abbreviated registration statements as may hereafter be required. Copies of such
registration statement and amendments, of each related prospectus subject to
completion (the "Preliminary Prospectuses") and of any abbreviated registration
statement pursuant to Rule 462(b) of the Rules and Regulations have been
delivered to you.

          If the registration statement relating to the Shares has been declared
effective under the Act by the Commission, the Company will prepare and promptly
file with the Commission the information omitted from the registration statement
pursuant to Rule 430A(a) or, if BancAmerica Robertson Stephens, on behalf of the
several Underwriters, shall agree to the utilization of Rule 434 of the Rules
and Regulations, the information required to be included in any term sheet filed
pursuant to Rule 434(b) or (c), as applicable, of the Rules and Regulations
pursuant to subparagraph (1), (4) or (7) of Rule 424(b) of the Rules and
Regulations or as part of a post-effective amendment to the registration
statement (including a final form of prospectus).  If the registration statement
relating to the Shares has not been declared effective under the Act by the
Commission, the Company will prepare and promptly file an amendment to the
registration statement, including a final form of prospectus, or, if BancAmerica
Robertson Stephens, on behalf of the several Underwriters, shall agree to the
utilization of Rule 434 of the Rules and Regulations, the information required
to be included in any term sheet filed pursuant to Rule 434(b) or (c), as
applicable, of the Rules and Regulations.  The term "Registration Statement" as
used in this Agreement shall mean such registration statement, including
financial statements, schedules and exhibits, in the form in which it became or
becomes, as the case may be, effective (including, if the Company omitted
information from the registration statement pursuant to Rule 430A(a) or files a
term sheet pursuant to Rule 434 of the Rules and Regulations, the information
deemed to be a part of the registration statement at the time it became
effective pursuant to Rule 430A(b) or Rule 434(d) of the Rules and Regulations)
and, in the event of any amendment thereto or the filing of any abbreviated
registration statement pursuant to Rule 462(b) of the Rules and Regulations
relating thereto after the effective date of such registration statement, shall
also mean (from and after the effectiveness of such amendment or the filing of
such abbreviated registration statement) such registration statement as so
amended, together with any such abbreviated registration statement.  The term
"Prospectus" as used in this Agreement shall mean the prospectus relating to the
Shares as included in such Registration Statement at the time it becomes
effective (including, if the Company omitted information from the Registration
Statement pursuant to Rule 430A(a) of the Rules and Regulations, the information
deemed to be a part of the Registration Statement at the time it became
effective pursuant to Rule 430A(b) of the Rules and Regulations); provided,
                                                                  -------- 
however, that if in reliance on Rule 434 of the Rules and Regulations and with
- -------                                                                       
the consent of BancAmerica Robertson Stephens, on behalf of the several
Underwriters, the Company shall have provided to the Underwriters a term sheet
pursuant to Rule 434(b) or (c), as applicable, prior to the time that a
confirmation is sent or given for purposes of Section 2(10)(a) of the Act, the
term "Prospectus" shall mean the "prospectus subject to completion" (as defined
in Rule 434(g) of the Rules and Regulations) last provided to the Underwriters
by the Company and circulated by the Underwriters to all prospective purchasers
of the Shares (including the information deemed to be a part of the Registration
Statement at the time it became effective pursuant to Rule 434(d) of the Rules
and Regulations).  Notwithstanding the foregoing, if any revised prospectus
shall be provided to the Underwriters by the Company for use in connection with
the offering of the Shares that differs from the prospectus referred to in the
immediately preceding sentence (whether or not such revised prospectus is
required to be filed with the Commission pursuant to Rule 424(b) of the Rules
and Regulations), the term "Prospectus" shall refer to such revised prospectus
from and after the time it is first provided to the 

                                      -2-
<PAGE>
 
Underwriters for such use. If in reliance on Rule 434 of the Rules and
Regulations and with the consent of BancAmerica Robertson Stephens, on behalf of
the several Underwriters, the Company shall have provided to the Underwriters a
term sheet pursuant to Rule 434(b) or (c), as applicable, prior to the time that
a confirmation is sent or given for purposes of Section 2(10)(a) of the Act, the
Prospectus and the term sheet, together, will not be materially different from
the prospectus in the Registration Statement.

                (b) The Commission has not issued any order preventing or
suspending the use of any Preliminary Prospectus or instituted proceedings for
that purpose, and each such Preliminary Prospectus has conformed in all material
respects to the requirements of the Act and the Rules and Regulations and, as of
its date, has not included any untrue statement of a material fact or omitted to
state a material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading; and at the time
the Registration Statement became or becomes, as the case may be, effective and
at all times subsequent thereto up to and on the Closing Date (hereinafter
defined) and on any later date on which Option Shares are to be purchased, (i)

thereto, contained and will contain all material information required to be
included therein by the Act and the Rules and Regulations and will in all
material respects conform to the requirements of the Act and the Rules and
Regulations, (ii) the Registration Statement, and any amendments or supplements
thereto, did not and will not include any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein not misleading, and (iii) the Prospectus, and any
amendments or supplements thereto, did not and will not include any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading; provided, however, that none of the representations and
                      -------- -------
warranties contained in this subparagraph (b) shall apply to information
contained in or omitted from the Registration Statement or Prospectus, or any
amendment or supplement thereto, in reliance upon, and in conformity with,
written information relating to any Underwriter furnished to the Company by such
Underwriter specifically for use in the preparation thereof.

                (c) Each of the Company and its subsidiaries has been duly

laws of the jurisdiction of its incorporation with full power and authority

capital stock of its subsidiaries free and clear of any pledge, lien, security
interest, encumbrance, claim or equitable interest; each of the Company and its
subsidiaries is duly qualified to do business as a foreign corporation and is in

material adverse effect on the condition (financial or otherwise), earnings,
operations, business or business prospects of the Company and its subsidiaries
considered as one enterprise; no proceeding has been instituted in any such
jurisdiction, revoking, limiting or curtailing, or seeking to revoke, limit or
curtail, such power and authority or qualification; each of the Company and its

or control, directly or indirectly, any corporation, association or other entity

                (f) All outstanding shares of capital stock of the Company
(including the Selling Stockholder Shares) have been duly authorized and validly
issued and are fully paid and nonassessable, have been issued in compliance with

outstanding any options to purchase, or any preemptive rights or other rights to
subscribe for or to purchase, any securities or obligations convertible into, or

its subsidiaries at the respective dates and for the respective periods to which

originally declared effective in reliance upon Rule 430A(a) of the Rules and
Regulations, the Company will provide evidence satisfactory to you that the
Prospectus contains such information and has been filed, within the time period
prescribed, with the Commission pursuant to subparagraph (1) or (4) of Rule
424(b) of the Rules and Regulations or as part of a post-effective amendment to
such Registration Statement as originally declared effective which is declared
effective by the Commission; if the Company files a term sheet pursuant to Rule
434 of the Rules and Regulations, the Company will provide evidence satisfactory
to you that the Prospectus and term sheet meeting the requirements of Rule
434(b) or (c), as applicable, of the Rules and Regulations, have been filed,
within the time period prescribed, with the Commission pursuant to subparagraph
(7) of Rule 424(b) of the Rules and Regulations; if for any reason the filing of
the final form of Prospectus is required under Rule 424(b)(3) of the Rules and
Regulations, it will provide evidence satisfactory to you that the Prospectus
contains such information and has been filed with the Commission within the time
period prescribed; it will notify you promptly of any request by the Commission
for the amending or supplementing of the Registration Statement or the
Prospectus or for additional information; promptly upon your request, it will
prepare and file with the Commission any amendments or supplements to the
Registration Statement or Prospectus which, in the opinion of counsel for the
several Underwriters ("Underwriters' Counsel"), may be necessary or advisable in
connection with the distribution of the Shares by the Underwriters; it will
promptly prepare and file with the Commission, and promptly notify you of the
filing of, any amendments or supplements to the Registration Statement or
Prospectus which may be necessary to correct any statements or omissions, if, at
any time when a prospectus relating to the Shares is required to be delivered
under the Act, any event shall have occurred as a result of which the Prospectus
or any other prospectus relating to the Shares as then in effect would include
any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading; in case any Underwriter is required
to deliver a prospectus nine (9) months or more after the effective date of the
Registration Statement in connection with the sale of the Shares, it will
prepare promptly upon request, but at the expense of such Underwriter, such
amendment or amendments to the Registration Statement and such prospectus or
prospectuses as may be necessary to permit compliance with the requirements of
Section 10(a)(3) of the Act; and it will file no amendment or supplement to the
Registration Statement or Prospectus which shall not previously have been
submitted to you a reasonable time prior to the proposed filing thereof or to
which you shall reasonably object in writing, subject, however, to compliance
with the Act and the Rules and Regulations and the provisions of this Agreement.

                (b)  The Company will advise you, promptly after it shall
receive notice or obtain knowledge, of the issuance of any stop order by the
Commission suspending the effectiveness of the Registration Statement or of the
initiation or threat of any proceeding for that purpose; and it will promptly
use its best efforts to prevent the issuance of any stop order or to obtain its
withdrawal at the earliest possible moment if such stop order should be issued .

                (c)  The Company will use its best efforts to qualify the Shares
for offering and sale under the securities laws of such jurisdictions as you may
designate and to continue such qualifications in effect for so long as may be
required for purposes of the distribution of the Shares, except that the Company
shall not be required in connection therewith or as a condition thereof to
qualify as a foreign corporation or to execute a general consent to service of
process in any jurisdiction in which it is not otherwise required to be so
qualified or to so execute a general consent to service of process. In each
jurisdiction in which the Shares shall have been qualified as above provided,
the Company will make and file such statements and reports in each year as are
or may be required by the laws of such jurisdiction.

                (d)  The Company will furnish to you, as soon as available, and,
in the case of the Prospectus and any term sheet or abbreviated term sheet under

first day that Shares are traded, copies of the Registration Statement (three of
which will be signed and which will include all exhibits), each Preliminary
Prospectus, the Prospectus and any amendments or supplements to such documents,
including any prospectus prepared to permit compliance with Section 10(a)(3) of

Notwithstanding the foregoing, if BancAmerica Robertson Stephens, on behalf of
the several Underwriters, shall agree to the utilization of Rule 434 of the
Rules and Regulations, the Company shall provide to you copies of a Preliminary
Prospectus updated in all respects through the date specified by you in such
quantities as you may from time to time reasonably request.

                (e)  The Company will make generally available to its
securityholders as soon as practicable, but in any event not later than the
forty-fifth (45th) day following the end of the fiscal quarter first occurring
after the first anniversary of the effective date of the Registration Statement,
an earnings statement (which will be in reasonable detail but need not be
audited) complying with the provisions of Section 11(a) of the Act and covering
a twelve (12) month period beginning after the effective date of the
Registration Statement.

                (f)  During a period of five (5) years after the date hereof,

or any of its subsidiaries, and (vi) any additional information of a public
nature concerning the Company or its subsidiaries, or its business which you may
reasonably request. During such five (5) year period, if the Company shall have
active subsidiaries, the foregoing financial statements shall be on a
consolidated basis to the extent that the accounts of the Company and its
subsidiaries are consolidated, and shall be accompanied by similar financial
statements for any significant subsidiary which is not so consolidated.

                (g)  The Company will apply the net proceeds from the sale of
the Shares being sold by it in the manner set forth under the caption "Use of
Proceeds" in the Prospectus.

                (h)  The Company will maintain a transfer agent and, if
necessary under the jurisdiction of incorporation of the Company, a registrar
(which may be the same entity as the transfer agent) for its Common Stock.

                (i)  If the transactions contemplated hereby are not consummated
by reason of any failure, refusal or inability on the part of the Company or the
Selling Stockholder to perform any agreement on their respective part to be
performed hereunder or to fulfill any condition of the Underwriters' obligations
hereunder, or if the Company shall terminate this Agreement pursuant to Section
11(a) hereof, or if the Underwriters shall terminate this Agreement pursuant to
Section 11(b)(i), the Company will reimburse the several Underwriters for all
out-of-pocket expenses (including fees and disbursements of Underwriters'
Counsel) incurred by the Underwriters in investigating or preparing to market or

                (j)  If at any time during the ninety (90) day period after the
Registration Statement becomes effective, any rumor, publication or event
relating to or affecting the Company shall occur as a result of which in your
opinion the market price of the Common Stock has been or is likely to be
materially affected (regardless of whether such rumor, publication or event
necessitates a supplement to or amendment of the Prospectus), the Company will,
after written notice from you advising the Company to the effect set forth
above, forthwith prepare, consult with you concerning the substance of and
disseminate a press release or other public statement, reasonably satisfactory
to you, responding to or commenting on such rumor, publication or event.

                (k)  During the Lock-up Period, the Company will not, without
the prior written consent of BancAmerica Robertson Stephens, effect the
Disposition of, directly or indirectly, any Securities other than the sale of
the Company Shares and the Option Shares to be sold by the Company hereunder and
the Company's issuance of options or Common Stock under the Company's presently
authorized ___________ (the "Option Plan").

                (l)  During a period of ninety (90) days from the effective date
of the Registration Statement, the Company will not file a registration
statement registering shares under the Option Plan or other employee benefit
plan.

5.  Expenses.
    -------- 
                (a)  The Company and the Selling Stockholder agree with each
Underwriter that:

                        (i) The Company and the Selling Stockholder will pay and
bear all costs and expenses in connection with the preparation, printing and
filing of the Registration Statement (including financial statements, schedules
and exhibits), Preliminary Prospectuses and the Prospectus and any amendments or
supplements thereto; the printing of this Agreement, the Agreement Among
Underwriters, the Selected Dealer Agreement, the Preliminary Blue Sky Survey and
any Supplemental Blue Sky Survey, the Underwriters' Questionnaire and Power of
Attorney, and any instruments related to any of the foregoing; the issuance and
delivery of the Shares hereunder to the several Underwriters, including transfer
taxes, if any, the cost of all certificates representing the Shares and transfer
agents' and registrars' fees; the fees and disbursements of counsel for the
Company; all fees and other charges of the Company's independent certified
public accountants; the cost of furnishing to the several Underwriters copies of
the Registration Statement (including appropriate exhibits), Preliminary
Prospectus and the Prospectus , and any amendments or supplements to any of the
foregoing; NASD filing fees and the cost of qualifying the Shares under the laws
of such jurisdictions as you may designate (including filing fees and fees and
disbursements of Underwriters' Counsel in connection with such NASD filings and
Blue Sky qualifications); and all other expenses directly incurred by the
Company and the Selling Stockholder in connection with the performance of their
obligations hereunder. Any additional expenses incurred as a result of the sale
of the Shares by the Selling Stockholder will be borne collectively by the
Company and the Selling Stockholder. The provisions of this Section 5(a)(i) are
intended to relieve the Underwriters from the payment of the expenses and costs
which the Selling Stockholder and the Company hereby agree to pay, but shall not
affect any agreement which the Selling Stockholder and the Company may make, or
may have made, for the sharing of any of such expenses and costs. Such
agreements shall not impair the obligations of the Company and the Selling
Stockholder hereunder to the several Underwriters.

                        (ii) In addition to its other obligations under Section
8(a) hereof, the Company agrees that, as an interim measure during the pendency
of any claim, action, investigation, inquiry or other proceeding described in
Section 8(a) hereof, it will reimburse the Underwriters on a monthly basis for
all reasonable legal or other expenses incurred in connection with investigating
or defending any such claim, action, investigation, inquiry or other proceeding,
notwithstanding the absence of a judicial determination as to the propriety and
enforceability of the Company's obligation to reimburse the Underwriters for
such expenses and the possibility that such payments might later be held to have
been improper by a court of competent 

                                      -14-
<PAGE>
 
jurisdiction. To the extent that any such interim reimbursement payment is so
held to have been improper, the Underwriters shall promptly return such payment
to the Company together with interest, compounded daily, determined on the basis
of the prime rate (or other commercial lending rate for borrowers of the highest
credit standing) listed from time to time in The Wall Street Journal which
represents the base rate on corporate loans posted by a substantial majority of
the nation's thirty (30) largest banks (the "Prime Rate"). Any such interim
reimbursement payments which are not made to the Underwriters within thirty (30)
days of a request for reimbursement shall bear interest at the Prime Rate from
the date of such request.

                        (iii)  In addition to its other obligations under
Section 8(b) hereof, the Selling Stockholder agrees that, as an interim measure
during the pendency of any claim, action, investigation, inquiry or other
proceeding described in Section 8(b) hereof relating to such Selling
Stockholder, it will reimburse the Underwriters on a monthly basis for all
reasonable legal or other expenses incurred in connection with investigating or
defending any such claim, action, investigation, inquiry or other proceeding,
notwithstanding the absence of a judicial determination as to the propriety and
enforceability of such Selling Stockholder's obligation to reimburse the
Underwriters for such expenses and the possibility that such payments might
later be held to have been improper by a court of competent jurisdiction. To the
extent that any such interim reimbursement payment is so held to have been
improper, the Underwriters shall promptly return such payment to the Selling
Stockholder, together with interest, compounded daily, determined on the basis
of the Prime Rate. Any such interim reimbursement payments which are not made to
the Underwriters within thirty (30) days of a request for reimbursement shall
bear interest at the Prime Rate from the date of such request.

                        (iv) In addition to their other obligations under
Section 8(c) hereof, the Underwriters, severally and not jointly, agree that, as
an interim measure during the pendency of any claim, action, investigation,
inquiry or other proceeding described in Section 8(c) hereof, they will
reimburse the Company and the Selling Stockholder on a monthly basis for all
reasonable legal or other expenses incurred in connection with investigating or
defending any such claim, action, investigation, inquiry or other proceeding,
notwithstanding the absence of a judicial determination as to the propriety and
enforceability of the Underwriters' obligation to reimburse the Company and such
Selling Stockholder for such expenses and the possibility that such payments
might later be held to have been improper by a court of competent jurisdiction.
To the extent that any such interim reimbursement payment is so held to have
been improper, the Company and such Selling Stockholder shall promptly return
such payment to the Underwriters together with interest, compounded daily,
determined on the basis of the Prime Rate. Any such interim reimbursement
payments which are not made to the Company and such Selling Stockholder within
thirty (30) days of a request for reimbursement shall bear interest at the Prime
Rate from the date of such request.

                (b)  It is agreed that any controversy arising out of the
operation of the interim reimbursement arrangements set forth in Sections
5(a)(ii), 5(a)(iii) and 5(a)(iv) hereof, including the amounts of any requested
reimbursement payments, the method of determining such amounts and the basis on
which such amounts shall be apportioned among the reimbursing parties, shall be
settled by arbitration conducted under the provisions of the Constitution and
Rules of the Board of Governors of the New York Stock Exchange, Inc. or pursuant
to the Code of Arbitration Procedure of the NASD. Any such arbitration must be
commenced by service of a written demand for arbitration or a written notice of
intention to arbitrate, therein electing the arbitration tribunal. In the event
the party demanding arbitration does not make such designation of an arbitration
tribunal in such demand or notice, then the party responding to said demand or
notice is authorized to do so. Any such arbitration will be limited to the
operation of the interim reimbursement provisions contained in Sections
5(a)(ii), 5(a)(iii) and 5(a)(iv) hereof and will not resolve the ultimate
propriety or enforceability of the obligation to indemnify for expenses which is
created by the provisions of Sections 8(a), 8(b) and 8(c) hereof or the
obligation to contribute to expenses which is created by the provisions of
Section 8(e) hereof.

        6.  Conditions of Underwriters' Obligations. The obligations of the
            ---------------------------------------
several Underwriters to purchase and pay for the Shares as provided herein shall
be subject to the accuracy, as of the date hereof and the Closing Date and any
later date on which Option Shares are to be purchased, as the case may be, of
the representations and warranties of the Company and the Selling Stockholder
herein, to the performance by the 

                                      -15-

Company and the Selling Stockholder of their respective obligations hereunder
and to the following additional conditions:

                (a)  The Registration Statement shall have become effective not
later than 5:00 P.M., New York time, on the date following the date of this
Agreement, or such later date as shall be consented to in writing by you; and no
stop order suspending the effectiveness thereof shall have been issued and no
proceedings for that purpose shall have been initiated or, to the knowledge of
the Company, the Selling Stockholder or any Underwriter, threatened by the
Commission, and any request of the Commission for additional information (to be
included in the Registration Statement or the Prospectus or otherwise) shall
have been complied with to the satisfaction of Underwriters' Counsel.

                (b)  All corporate proceedings and other legal matters in
connection with this Agreement, the form of Registration Statement and the
Prospectus, and the registration, authorization, issue, sale and delivery of the
Shares, shall have been reasonably satisfactory to Underwriters' Counsel, and
such counsel shall have been furnished with such papers and information as they
may reasonably have requested to enable them to pass upon the matters referred
to in this Section.

                (c)  Subsequent to the execution and delivery of this Agreement
and prior to the Closing Date, or any later date on which Option Shares are to
be purchased, as the case may be, there shall not have been any change in the
condition (financial or otherwise), earnings, operations, business or business
prospects of the Company and its subsidiaries considered as one enterprise from
that set forth in the Registration Statement or Prospectus, which, in your sole
judgment, is material and adverse and that makes it, in your sole judgment,
impracticable or inadvisable to proceed with the public offering of the Shares
as contemplated by the Prospectus; and

                (d)  You shall have received on the Closing Date and on any
later date on which Option Shares are to be purchased, as the case may be, the
following opinion of counsel for the Company and the Selling Stockholder, dated
the Closing Date or such later date on which Option Shares are to be purchased
addressed to the Underwriters and with reproduced copies or signed counterparts
thereof for each of the Underwriters, to the effect that:

     standing in each jurisdiction, if any, in which the ownership or leasing of
     its properties or the conduct of its business requires such qualification,
     except where the failure to be so qualified or be in good standing would
     not have a material adverse effect on the condition (financial or
     otherwise), earnings, operations, business or business prospects of the
     Company and its subsidiaries considered as one enterprise. To such
     counsel's knowledge, the Company does not own or control, directly or
     indirectly, any corporation, association or other entity other than Knight

     knowledge, have not been issued in violation of or subject to any
     preemptive right, co-sale right, registration right, right of first refusal
     or other similar right and are owned by the Company free and clear of any
     pledge, lien, security interest, encumbrance, claim or equitable interest;

                        (vi) The Firm Shares or the Option Shares, as the case
     may be, to be issued by the Company pursuant to the terms of this Agreement
     have been duly authorized and, upon issuance and delivery against payment
     therefor in accordance with the terms hereof, will be duly and validly
     issued and fully paid and nonassessable, and will not have been issued in

     execution and delivery by you, is a valid and binding agreement of the
     Company, enforceable in accordance with its terms, except insofar as
     indemnification provisions may be limited by applicable law and except as
     enforceability may be limited by bankruptcy, insolvency, reorganization,
     moratorium or similar laws relating to or affecting creditors' rights
     generally or by general equitable principles;

                        (ix) The Registration Statement has become effective
     under the Act and, to such counsel's knowledge, no stop order suspending
     the effectiveness of the Registration Statement has been issued and no
     proceedings for that purpose have been instituted or are pending or
     threatened under the Act;

                        (x) The Registration Statement and the Prospectus, and

     the Registration Statement, complied as to form in all material respects
     with the requirements of the Act and the applicable Rules and Regulations;

     agreements, contracts, leases or documents to which the Company is a party

     to the Registration Statement which are not described or referred to
     therein or filed as required;

                        (xiv)  The performance of this Agreement and the
     consummation of the transactions herein contemplated (other than
     performance of the Company's indemnification obligations hereunder,
     concerning which no opinion need be expressed) will not (a) result in any
     violation of the Company's charter or bylaws or (b) to such counsel's
     knowledge, result in a material breach or violation of any of the terms and
     provisions of, or constitute a default under, any bond, debenture, note or
     other evidence of indebtedness, or any lease, contract, indenture,
     mortgage, deed of trust, loan agreement, joint venture or other agreement
     or instrument known to such counsel to which the Company is a party or by
     which its properties are bound, or any applicable statute, rule or
     regulation known to such counsel or, to such counsel's knowledge, any
     order, writ or decree of any court, government or governmental agency or
     body having jurisdiction over the Company or any of its subsidiaries, or
     over any of their properties or operations;

                        (xv) No consent, approval, authorization or order of or
     qualification with any court, government or governmental agency or body
     having jurisdiction over the Company or any of its subsidiaries, or over
     any of their properties or operations is necessary in connection with the
     consummation by the Company of the transactions herein contemplated, except

     file the Registration Statement or have included securities in the
     Registration Statement pursuant to the exercise of and in full satisfaction
     of such rights;

                        (xix)  The Selling Stockholder has full right, power and
     authority to enter into and to perform its obligations under the Power of
     Attorney and Custody Agreement to be executed and delivered by it in
     connection with the transactions contemplated herein; the Power of Attorney
     and Custody Agreement of the Selling Stockholder has been duly authorized;
     the Power of Attorney and Custody Agreement of the Selling Stockholder has
     been duly executed and delivered by or on behalf of such Selling
     Stockholder; and the Power of Attorney and Custody Agreement of the Selling
     Stockholder constitutes the valid and binding agreement of such Selling
     Stockholder, enforceable in accordance with its terms, except as the
     enforcement thereof may be limited by bankruptcy, insolvency,
     reorganization, moratorium or other similar laws relating to or affecting
     creditors' rights generally or by general equitable principles;

                        (xx) The Selling Stockholder has full right, power and
     authority to enter into and to perform its obligations under this Agreement
     and to sell, transfer, assign and deliver the Shares to be sold by such
     Selling Stockholder hereunder;

                        (xxi)  This Agreement has been duly authorized by the
     Selling Stockholder and has been duly executed and delivered by or on
     behalf of the Selling Stockholder; and

                        (xxii)  Upon the delivery of and payment for the Shares
     as contemplated in this Agreement, each of the Underwriters will receive
     valid marketable title to the Shares purchased by it from such Selling
     Stockholder, free and clear of any pledge, lien, security interest,
     encumbrance, claim or equitable interest. In rendering such opinion, such
     counsel may assume that the Underwriters are without notice of any defect
     in the title of the Shares being purchased from the Selling Stockholder.

          In addition, such counsel shall state that such counsel has
participated in conferences with officials and other representatives of the
Company, the Representatives, Underwriters' Counsel and the independent
certified public accountants of the Company, at which such conferences the
contents of the Registration Statement and Prospectus and related matters were
discussed, and although they have not verified the accuracy or completeness of
the statements contained in the Registration Statement or the Prospectus,
nothing has come to the attention of such counsel which leads them to believe
that, at the time the Registration Statement became effective and at all times
subsequent thereto up to and on the Closing Date and on any later date on which
Option Shares are to be purchased, the Registration Statement and any amendment
or supplement thereto (other than the financial statements including supporting
schedules and other financial and statistical information derived therefrom, as
to which such counsel need express no comment) contained any untrue statement of
a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, or at the
Closing Date or any later date on which the Option Shares are to be purchased,
as the case may be, the Registration Statement, the Prospectus and any amendment
or supplement thereto (except as aforesaid) contained any untrue statement of a
material fact or omitted to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

          Counsel rendering the foregoing opinion may rely as to questions of
law not involving the laws of the United States or the States of New York and
Delaware upon opinions of local counsel, and as to questions of fact upon
representations or certificates of officers of the Company, the Selling
Stockholder or officers of the Selling Stockholder (when the Selling Stockholder
is not a natural person), and of government officials, in which case their
opinion is to state that they are so relying and that they have no knowledge of
any material misstatement or inaccuracy in any such opinion, representation or
certificate.  Copies of any opinion, representation or certificate so relied
upon shall be delivered to you, as Representatives of the Underwriters, and to
Underwriters' Counsel.

                (e)  You shall have received on the Closing Date and on any
later date on which Option Shares are to be purchased, as the case may be, an
opinion of Brobeck, Phleger & Harrison LLP, in form and substance satisfactory
to you, with respect to the sufficiency of all such corporate proceedings and
other legal matters relating to this Agreement and the transactions contemplated
hereby as you may reasonably require, and the Company shall have furnished to
such counsel such documents as they may have requested for the purpose of
enabling them to pass upon such matters.

                (f)  You shall have received on the Closing Date and on any
later date on which Option Shares are to be purchased, as the case may be, a
letter from Price Waterhouse LLP addressed to the Underwriters, dated the
Closing Date or such later date on which Option Shares are to be purchased, as
the case may be, confirming that they are independent certified public
accountants with respect to the Company within the meaning of the Act and the
applicable published Rules and Regulations and based upon the procedures
described in such letter delivered to you concurrently with the execution of
this Agreement (herein called the "Original Letter"), but carried out to a date
not more than five (5) business days prior to the Closing Date or 

                                      -19-
<PAGE>
 
such later date on which Option Shares are to be purchased, as the case may be,
(i) confirming, to the extent true, that the statements and conclusions set
forth in the Original Letter are accurate as of the Closing Date or such later
date on which Option Shares are to be purchased, as the case may be, and (ii)
setting forth any revisions and additions to the statements and conclusions set
forth in the Original Letter which are necessary to reflect any changes in the
facts described in the Original Letter since the date of such letter, or to
reflect the availability of more recent financial statements, data or
information. The letter shall not disclose any change in the condition
(financial or otherwise), earnings, operations, business or business prospects
of the Company and its subsidiaries considered as one enterprise from that set
forth in the Registration Statement or Prospectus, which, in your sole judgment,
is material and adverse and that makes it, in your sole judgment, impracticable
or inadvisable to proceed with the public offering of the Shares as contemplated
by the Prospectus. The Original Letter from Price Waterhouse LLP shall be
addressed to or for the use of the Underwriters in form and substance
satisfactory to the Underwriters and shall (i) represent, to the extent true,
that they are independent certified public accountants with respect to the
Company within the meaning of the Act and the applicable published Rules and
Regulations, (ii) set forth their opinion with respect to their examination of
the consolidated balance sheet of the Company as of [________], 199[ ] and
related consolidated statements of operations, stockholders' equity, and cash
flows for the twelve (12) months ended [_________], 199[ ], (iii) state that
Price Waterhouse LLP has performed the procedures set out in Statement on
Auditing Standards No. 71 ("SAS 71") for a review of interim financial
information and providing the report of Price Waterhouse LLP as described in SAS
71 on the financial statements for each of the quarters in the nine quarter
period ended March 31, 1998 (the "Quarterly Financial Statements"), (iv) state
that in the course of such review, nothing came to their attention that leads
them to believe that any material modifications need to be made to any of the
Quarterly Financial Statements in order for them to be in compliance with
generally accepted accounting principles consistently applied across the periods
presented, and (v) address other matters agreed upon by Price Waterhouse LLP and
you. In addition, you shall have received from Price Waterhouse LLP a letter
addressed to the Company and made available to you for the use of the
Underwriters stating that their review of the Company's system of internal
accounting controls, to the extent they deemed necessary in establishing the
scope of their examination of the Company's consolidated financial statements as
of December 31, 1997, did not disclose any weaknesses in internal controls that
they considered to be material weaknesses.

                (g)  You shall have received on the Closing Date and on any
later date on which Option Shares are to be purchased, as the case may be, a
certificate of the Company, dated the Closing Date or such later date on which
Option Shares are to be purchased, as the case may be, signed by the Chief
Executive Officer and Chief Financial Officer of the Company, to the effect
that, and you shall be satisfied that: 

                        (i) The representations and warranties of the Company in
     this Agreement are true and correct, as if made on and as of the Closing
     Date or any later date on which Option Shares are to be purchased, as the
     case may be, and the Company has complied with all the agreements and
     satisfied all the conditions on its part to be performed or satisfied at or
     prior to the Closing Date or any later date on which Option Shares are to
     be purchased, as the case may be;

                       (ii) No stop order suspending the effectiveness of the
     Registration Statement has been issued and no proceedings for that purpose
     have been instituted or are pending or threatened under the Act;

                       (iii)  When the Registration Statement became effective
     and at all times subsequent thereto up to the delivery of such certificate,
     the Registration Statement and the Prospectus, and any amendments or
     supplements thereto, contained all material information required to be
     included therein by the Act and the Rules and Regulations and in all
     material respects conformed to the requirements of the Act and the Rules
     and Regulations, the Registration Statement, and any amendment or
     supplement thereto, did not and does not include any untrue statement of a
     material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading, the
     Prospectus, and any amendment or supplement thereto, did not and does not
     include any untrue statement of a material fact or omit to state a material
     fact necessary to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, and, 

                                      -20-
<PAGE>
 
     since the effective date of the Registration Statement, there has occurred
     no event required to be set forth in an amended or supplemented Prospectus
     which has not been so set forth; and

                        (iv) Subsequent to the respective dates as of which
     information is given in the Registration Statement and Prospectus, there
     has not been (a) any material adverse change in the condition (financial or
     otherwise), earnings, operations, business or business prospects of the
     Company and its subsidiaries considered as one enterprise, (b) any
     transaction that is material to the Company and its subsidiaries considered
     as one enterprise, except transactions entered into in the ordinary course
     of business, (c) any obligation, direct or contingent, that is material to
     the Company and its subsidiaries considered as one enterprise, incurred by
     the Company or its subsidiaries, except obligations incurred in the
     ordinary course of business, (d) any change in the capital stock or
     outstanding indebtedness of the Company or any of its subsidiaries that is
     material to the Company and its subsidiaries considered as one enterprise,
     (e) any dividend or distribution of any kind declared, paid or made on the
     capital stock of the Company or any of its subsidiaries, or (f) any loss or
     damage (whether or not insured) to the property of the Company or any of
     its subsidiaries which has been sustained or will have been sustained which
     has a material adverse effect on the condition (financial or otherwise),
     earnings, operations, business or business prospects of the Company and its
     subsidiaries considered as one enterprise.

                (h)  You shall be satisfied that, and you shall have received a
certificate, dated the Closing Date from the Attorneys for the Selling
Stockholder to the effect that, as of the Closing Date, they have not been
informed that:

                       (i) The representations and warranties made by such
     Selling Stockholder herein are not true or correct in any material respect
     on the Closing Date; or

                       (ii) Such Selling Stockholder has not complied with any
     obligation or satisfied any condition which is required to be performed or
     satisfied on the part of such Selling Stockholder at or prior to the
     Closing Date.

                (i)  The Company shall have obtained and delivered to you an
agreement from each officer and director of the Company, the Selling Stockholder
and each beneficial owner of shares of Common Stock in writing prior to the date
hereof that such person will not, during the Lock-up Period, effect the
Disposition of any Securities now owned or hereafter acquired directly by such
person or with respect to which such person has or hereafter acquires the power
of disposition, otherwise than (i) as a bona fide gift or gifts, provided the
donee or donees thereof agree in writing to be bound by this restriction, (ii)
as a distribution to partners or stockholders of such person, provided that the
distributees thereof agree in writing to be bound by the terms of this
restriction, (iii) to the extent that such person is a "Nasdaq market maker" (as
defined in Rule 4200(17) of the Marektplace Rules of the NASD), any Dispositiion
of Securities in connection with market-making activities in the ordinary course
of the business of such person, or (iv) with the prior written consent of
BancAmerica Robertson Stephens. Except as otherwise specifically contemplated by
subparagraph (iii) above, the foregoing restriction shall have been expressly
agreed to preclude the holder of the Securities from engaging in any hedging or
other transaction which is designed to or reasonably expected to lead to or
result in a Disposition of Securities during the Lock-up Period, even if such
Securities would be disposed of by someone other than the such holder. Such
prohibited hedging or other transactions would including, without limitation,
any short sale (whether or not against the box) or any purchase, sale or grant
of any right (including, without limitation, any put or call option) with
respect to any Securities or with respect to any security (other than a broad-
based market basket or index) that includes, relates to or derives any
significant part of its value from Securities. Furthermore, such person will
have also agreed and consented to the entry of stop transfer instructions with
the Company's transfer agent against the transfer of the Securities held by such
person except in compliance with this restriction.

                (j)  The Company and the Selling Stockholder shall have
furnished to you such further certificates and documents as you shall reasonably
request (including certificates of officers of the 

                                      -21-
<PAGE>
 
Company, the Selling Stockholder or officers of the Selling Stockholder (when
the Selling Stockholder is not a natural person) as to the accuracy of the
representations and warranties of the Company and the Selling Stockholder
herein, as to the performance by the Company and the Selling Stockholder of
their respective obligations hereunder and as to the other conditions concurrent
and precedent to the obligations of the Underwriters hereunder.

          All such opinions, certificates, letters and documents will be in
compliance with the provisions hereof only if they are reasonably satisfactory
to Underwriters' Counsel.  The Company and the Selling Stockholder will furnish
you with such number of conformed copies of such opinions, certificates, letters
and documents as you shall reasonably request.

        7.  Option Shares.
            ------------- 

                (a)  On the basis of the representations, warranties and
agreements herein contained, but subject to the terms and conditions herein set
forth, the Company hereby grants to the several Underwriters, for the purpose of
covering over-allotments in connection with the distribution and sale of the
Firm Shares only, a nontransferable option to purchase up to an aggregate of
________ Option Shares at the purchase price per share for the Firm Shares set
forth in Section 3 hereof. Such option may be exercised by the Representatives
on behalf of the several Underwriters on one (1) or more occasions in whole or
in part during the period of thirty (30) days after the date on which the Firm
Shares are initially offered to the public, by giving written notice to the
Company. The number of Option Shares to be purchased by each Underwriter upon
the exercise of such option shall be the same proportion of the total number of
Option Shares to be purchased by the several Underwriters pursuant to the
exercise of such option as the number of Firm Shares purchased by such
Underwriter (set forth in Schedule A hereto) bears to the total number of Firm
                          ----------
Shares purchased by the several Underwriters (set forth in Schedule A
                                                           ----------
hereto), adjusted by the Representatives in such manner as to avoid
fractional shares.

          Delivery of definitive certificates for the Option Shares to be
purchased by the several Underwriters pursuant to the exercise of the option
granted by this Section 7 shall be made against payment of the purchase price
therefor by the several Underwriters by certified or official bank check or
checks drawn in next-day funds, payable to the order of the Company (and the
Company agrees not to deposit any such check in the bank on which it is drawn,
and not to take any other action with the purpose or effect of receiving
immediately available funds, until the business day following the date of its
delivery to the Company).  In the event of any breach of the foregoing, the
Company shall reimburse the Underwriters for the interest lost and any other
expenses borne by them by reason of such breach.  Such delivery and payment
shall take place at the offices of Skadden, Arps, Slate, Meagher & Flom, LLP,
919 Third Avenue, New York, New York 10022-3897 or at such other place as may be
agreed upon among the Representatives and the Company (i) on the Closing Date,
if written notice of the exercise of such option is received by the Company at
least two (2) full business days prior to the Closing Date, or (ii) on a date
which shall not be later than the third (3rd) full business day following the
date the Company receives written notice of the exercise of such option, if such
notice is received by the Company less than two (2) full business days prior to
the Closing Date.

          The certificates for the Option Shares to be so delivered will be made
available to you at such office or such other location including, without
limitation, in New York City, as you may reasonably request for checking at
least one (1) full business day prior to the date of payment and delivery and
will be in such names and denominations as you may request, such request to be
made at least two (2) full business days prior to such date of payment and
delivery.  If the Representatives so elect, delivery of the Option Shares may be
made by credit through full fast transfer to the accounts at The Depository
Trust Company designated by the Representatives.

          It is understood that you, individually, and not as the
Representatives of the several Underwriters, may (but shall not be obligated to)
make payment of the purchase price on behalf of any Underwriter or Underwriters
whose check or checks shall not have been received by you prior to the date of

                                      -22-
<PAGE>
 
payment and delivery for the Option Shares to be purchased by such Underwriter
or Underwriters.  Any such payment by you shall not relieve any such Underwriter
or Underwriters of any of its or their obligations hereunder.

                (b)  Upon exercise of any option provided for in Section 7(a)
hereof, the obligations of the several Underwriters to purchase such Option
Shares will be subject (as of the date hereof and as of the date of payment and
delivery for such Option Shares) to the accuracy of and compliance with the
representations, warranties and agreements of the Company and the Selling
Stockholder herein, to the accuracy of the statements of the Company, the
Selling Stockholder and officers of the Company made pursuant to the provisions
hereof, to the performance by the Company and the Selling Stockholder of their
respective obligations hereunder, to the conditions set forth in Section 6
hereof, and to the condition that all proceedings taken at or prior to the
payment date in connection with the sale and transfer of such Option Shares
shall be satisfactory in form and substance to you and to Underwriters' Counsel,
and you shall have been furnished with all such documents, certificates and
opinions as you may request in order to evidence the accuracy and completeness
of any of the representations, warranties or statements, the performance of any
of the covenants or agreements of the Company and the Selling Stockholder or the
satisfaction of any of the conditions herein contained.

        8.  Indemnification and Contribution.
            -------------------------------- 

                (a)  The Company agrees to indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject (including, without
limitation, in its capacity as an Underwriter or as a "qualified independent
underwriter" within the meaning of Rule 2720 of the Conduct Rules of the NASD),
under the Act, the Exchange Act or otherwise, specifically including, but not
limited to, losses, claims, damages or liabilities (or actions in respect
thereof) arising out of or based upon (i) any breach of any representation,
warranty, agreement or covenant of the Company herein contained, (ii) any untrue
statement or alleged untrue statement of any material fact contained in the
Registration Statement or any amendment or supplement thereto, or the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, or (iii) any
untrue statement or alleged untrue statement of any material fact contained in
any Preliminary Prospectus or the Prospectus or any amendment or supplement
thereto, or the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, and
agrees to reimburse each Underwriter for any legal or other expenses reasonably
incurred by it in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that the Company shall
                                    --------  -------
not be liable in any such case to the extent that any such loss, claim, damage,
liability or action arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in the
Registration Statement, such Preliminary Prospectus or the Prospectus, or any
such amendment or supplement thereto, in reliance upon, and in conformity with,
written information relating to any Underwriter furnished to the Company by such
Underwriter, directly or through you, specifically for use in the preparation
thereof and, provided further, that the indemnity agreement provided in this
Section 8(a) with respect to any Preliminary Prospectus shall not inure to the
benefit of any Underwriter from whom the person asserting any losses, claims,
damages, liabilities or actions based upon any untrue statement or alleged
untrue statement of material fact or omission or alleged omission to state
therein a material fact purchased Shares, if a copy of the Prospectus in which
such untrue statement or alleged untrue statement or omission or alleged
omission was corrected had not been sent or given to such person within the time
required by the Act and the Rules and Regulations, unless such failure is the
result of noncompliance by the Company with Section 4(d) hereof.

          The indemnity agreement in this Section 8(a) shall extend upon the
same terms and conditions to, and shall inure to the benefit of, each person, if
any, who controls any Underwriter within the meaning of the Act or the Exchange
Act.  This indemnity agreement shall be in addition to any liabilities which the

                                      -23-
<PAGE>
 
Company may otherwise have.

                (b)  The Selling Stockholder agrees to indemnify and hold
harmless each Underwriter against any losses, claims, damages or liabilities,
joint or several, to which such Underwriter may become subject (including,
without limitation, in its capacity as an Underwriter or as a "qualified
independent underwriter" within the meaning of Rule 2720 of the Conduct Rules of
the NASD) under the Act, the Exchange Act or otherwise, specifically including,
but not limited to, losses, claims, damages or liabilities (or actions in
respect thereof) arising out of or based upon (i) any breach of any
representation, warranty, agreement or covenant of such Selling Stockholder
herein contained, (ii) any untrue statement or alleged untrue statement of any
material fact contained in the Registration Statement or any amendment or
supplement thereto, or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or (iii) any untrue statement or alleged untrue
statement of any material fact contained in any Preliminary Prospectus or the
Prospectus or any amendment or supplement thereto, or the omission or alleged
omission to state therein a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, in the case of subparagraphs (ii) and (iii) of this Section 8(b) to
the extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company or such Underwriter
by such Selling Stockholder, directly or through such Selling Stockholder's
representatives, specifically for use in the preparation thereof, and agrees to
reimburse each Underwriter for any legal or other expenses reasonably incurred
by it in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the indemnity agreement
                             --------  -------
provided in this Section 8(b) with respect to any Preliminary Prospectus shall
not inure to the benefit of any Underwriter from whom the person asserting any
losses, claims, damages, liabilities or actions based upon any untrue statement
or alleged untrue statement of a material fact or omission or alleged omission
to state therein a material fact purchased Shares, if a copy of the Prospectus
in which such untrue statement or alleged untrue statement or omission or
alleged omission was corrected had not been sent or given to such person within
the time required by the Act and the Rules and Regulations, unless such failure
is the result of noncompliance by the Company with Section 4(d) hereof.

          The indemnity agreement in this Section 8(b) shall extend upon the
same terms and conditions to, and shall inure to the benefit of, each person, if
any, who controls any Underwriter within the meaning of the Act or the Exchange
Act.  This indemnity agreement shall be in addition to any liabilities which
such Selling Stockholder may otherwise have.

                (c)  Each Underwriter, severally and not jointly, agrees to
indemnify and hold harmless the Company and the Selling Stockholder against any
losses, claims, damages or liabilities, joint or several, to which the Company
or such Selling Stockholder may become subject under the Act or otherwise,
specifically including, but not limited to, losses, claims, damages or
liabilities (or actions in respect thereof) arising out of or based upon (i) any
breach of any representation, warranty, agreement or covenant of such
Underwriter herein contained, (ii) any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement or any
amendment or supplement thereto, or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, or (iii) any untrue statement or alleged
untrue statement of any material fact contained in any Preliminary Prospectus or
the Prospectus or any amendment or supplement thereto, or the omission or
alleged omission to state therein a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, in the case of subparagraphs (ii) and (iii) of this
Section 8(c) to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with written information furnished to the Company by such
Underwriter, directly or through you, specifically for use in the preparation
thereof, and agrees to reimburse the Company and the such Selling Stockholder
for any legal or other expenses reasonably incurred by the Company and such
Selling Stockholder in connection with investigating or defending any such loss,
claim, damage, liability or action.

          The indemnity agreement in this Section 8(c) shall extend upon the
same terms and conditions to, and shall inure to the benefit of, each officer of
the Company who signed the Registration Statement and each director of the
Company, the Selling Stockholder and each person, if any, who controls the
Company or 

                                      -24-
<PAGE>
 
the Selling Stockholder within the meaning of the Act or the Exchange Act. This
indemnity agreement shall be in addition to any liabilities which each
Underwriter may otherwise have.

                (d)  Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against any indemnifying
party under this Section 8, notify the indemnifying party in writing of the
commencement thereof but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under this Section 8. In case any such action is brought against
any indemnified party, and it notified the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it shall elect by written notice delivered to
the indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party; provided, however, that if the
                                        --------  -------
defendants in any such action include both the indemnified party
and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of the indemnifying party's election so to assume the defense of such
action and approval by the indemnified party of counsel, the indemnifying party
will not be liable to such indemnified party under this Section 8 for any legal
or other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate counsel (together with appropriate
local counsel) approved by the indemnifying party representing all the
indemnified parties under Section 8(a), 8(b) or 8(c) hereof who are parties to
such action), (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of commencement of the action or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party. In no event shall any
indemnifying party be liable in respect of any amounts paid in settlement of any
action unless the indemnifying party shall have approved the terms of such
settlement; provided that such consent shall not be unreasonably withheld. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect
of which any indemnified party is or could have been a party and indemnification
could have been sought hereunder by such indemnified party, unless such
settlement includes an unconditional release of such indemnified party from all
liability on all claims that are the subject matter of such proceeding.

                (e)  In order to provide for just and equitable contribution in
any action in which a claim for indemnification is made pursuant to this Section
8 but it is judicially determined (by the entry of a final judgment or decree by
a court of competent jurisdiction and the expiration of time to appeal or the
denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 8 provides for
indemnification in such case, all the parties hereto shall contribute to the
aggregate losses, claims, damages or liabilities to which they may be subject
(after contribution from others) in such proportion so that, except as set forth
in Section 8(f) hereof, the Underwriters severally and not jointly are
responsible pro rata for the portion represented by the percentage that the
underwriting discount bears to the initial public offering price, and the
Company and the Selling Stockholder are responsible for the remaining portion,
provided, however, that (i) no Underwriter shall be required to
- --------  -------
contribute any amount in excess of the amount by which the underwriting discount
applicable to the Shares purchased by such Underwriter exceeds the amount of
damages which such Underwriter has otherwise required to pay and (ii) no person
guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who is not guilty of
such fraudulent misrepresentation. The contribution agreement in this Section
8(e) shall extend upon the same terms and conditions to, and shall inure to the
benefit of, each person, if any, who controls any Underwriter, the Company or
the Selling Stockholder within the meaning of the Act or the Exchange Act and
each officer of the Company who signed the Registration Statement and each
director of the Company.

                                      -25-

                (f)  The liability of the Selling Stockholder under the
representations, warranties and agreements contained herein and under the
indemnity agreements contained in the provisions of this Section 8 shall be
limited to an amount equal to the initial public offering price of the Selling
Stockholder Shares sold by such Selling Stockholder to the Underwriters minus
the amount of the underwriting discount paid thereon to the Underwriters by such
Selling Stockholder. The Company and such Selling Stockholder may agree, as
among themselves and without limiting the rights of the Underwriters under this
Agreement, as to the respective amounts of such liability for which they each
shall be responsible.

                (g)  The parties to this Agreement hereby acknowledge that they
are sophisticated business persons who were represented by counsel during the
negotiations regarding the provisions hereof including, without limitation, the
provisions of this Section 8, and are fully informed regarding said provisions.
They further acknowledge that the provisions of this Section 8 fairly allocate
the risks in light of the ability of the parties to investigate the Company and
its business in order to assure that adequate disclosure is made in the
Registration Statement and Prospectus as required by the Act and the Exchange
Act.

        9.  Representations, Warranties, Covenants and Agreements to Survive
            ----------------------------------------------------------------
Delivery. All representations, warranties, covenants and agreements of the
- --------
Company, the Selling Stockholder and the Underwriters herein or in certificates
delivered pursuant hereto, and the indemnity and contribution agreements
contained in Section 8 hereof shall remain operative and in full force and
effect regardless of any investigation made by or on behalf of any Underwriter
or any person controlling any Underwriter within the meaning of the Act or the
Exchange Act, or by or on behalf of the Company or the Selling Stockholder, or
any of their officers, directors or controlling persons within the meaning of
the Act or the Exchange Act, and shall survive the delivery of the Shares to the
several Underwriters hereunder or termination of this Agreement.

        10. Substitution of Underwriters.  If any Underwriter or Underwriters 
            ---------------------------- 
shall fail to take up and pay for the number of Firm Shares agreed by such
Underwriter or Underwriters to be purchased hereunder upon tender of such Firm
Shares in accordance with the terms hereof, and if the aggregate number of Firm
Shares which such defaulting Underwriter or Underwriters so agreed but failed to
purchase does not exceed 10% of the Firm Shares, the remaining Underwriters
shall be obligated, severally in proportion to their respective commitments
hereunder, to take up and pay for the Firm Shares of such defaulting Underwriter
or Underwriters.

          If any Underwriter or Underwriters so defaults and the aggregate
number of Firm Shares which such defaulting Underwriter or Underwriters agreed
but failed to take up and pay for exceeds 10% of the Firm Shares, the remaining
Underwriters shall have the right, but shall not be obligated, to take up and
pay for (in such proportions as may be agreed upon among them) the Firm Shares
which the defaulting Underwriter or Underwriters so agreed but failed to
purchase.  If such remaining Underwriters do not, at the Closing Date, take up
and pay for the Firm Shares which the defaulting Underwriter or Underwriters so
agreed but failed to purchase, the Closing Date shall be postponed for twenty-
four (24) hours to allow the several Underwriters the privilege of substituting
within twenty-four (24) hours (including non-business hours) another underwriter
or underwriters (which may include any nondefaulting Underwriter) satisfactory
to the Company.  If no such underwriter or underwriters shall have been
substituted as aforesaid by such postponed Closing Date, the Closing Date may,
at the option of the Company, be postponed for a further twenty-four (24) hours,
if necessary, to allow the Company the privilege of finding another underwriter
or underwriters, satisfactory to you, to purchase the Firm Shares which the
defaulting Underwriter or Underwriters so agreed but failed to purchase.  If it
shall be arranged for the remaining Underwriters or substituted underwriter or
underwriters to take up the Firm Shares of the defaulting Underwriter or
Underwriters as provided in this Section 10, (i) the Company shall have the
right to postpone the time of delivery for a period of not more than seven (7)
full business days, in order to effect whatever changes may thereby be made
necessary in the Registration Statement or the Prospectus, or in any other
documents or arrangements, and the Company agrees promptly to file any
amendments to the Registration Statement, supplements to the Prospectus or other
such documents which may thereby be made necessary, and (ii) the respective
number of Firm Shares to be purchased by the remaining Underwriters and
substituted underwriter or underwriters shall be taken as the basis of their
underwriting 

                                      -26-
<PAGE>
 
obligation. If the remaining Underwriters shall not take up and pay for all such
Firm Shares so agreed to be purchased by the defaulting Underwriter or
Underwriters or substitute another underwriter or underwriters as aforesaid and
the Company shall not find or shall not elect to seek another underwriter or
underwriters for such Firm Shares as aforesaid, then this Agreement shall
terminate.

          In the event of any termination of this Agreement pursuant to the
preceding paragraph of this Section 10, neither the Company nor the Selling
Stockholder shall be liable to any Underwriter (except as provided in Sections 5
and 8 hereof) nor shall any Underwriter (other than an Underwriter who shall
have failed, otherwise than for some reason permitted under this Agreement, to
purchase the number of Firm Shares agreed by such Underwriter to be purchased
hereunder, which Underwriter shall remain liable to the Company, the Selling
Stockholder and the other Underwriters for damages, if any, resulting from such
default) be liable to the Company or the Selling Stockholder (except to the
extent provided in Sections 5 and 8 hereof).

          The term "Underwriter" in this Agreement shall include any person
substituted for an Underwriter under this Section 10.

        11. Effective Date of this Agreement and Termination.
            ------------------------------------------------ 

                (a)  This Agreement shall become effective at the earlier of (i)
9:30 A.M., New York time, on the first full business day following the effective
date of the Registration Statement, or (ii) the time of the initial public
offering of any of the Shares by the Underwriters after the Registration
Statement becomes effective. The time of the initial public offering shall mean
the time of the release by you, for publication, of the first newspaper
advertisement relating to the Shares, or the time at which the Shares are first
generally offered by the Underwriters to the public by letter, telephone,
telegram or telecopy, whichever shall first occur. By giving notice as set forth
in Section 12 before the time this Agreement becomes effective, you, as
Representatives of the several Underwriters, or the Company, may prevent this
Agreement from becoming effective without liability of any party to any other
party, except as provided in Sections 4(i), 5 and 8 hereof.

                (b)  You, as Representatives of the several Underwriters, shall
have the right to terminate this Agreement by giving notice as hereinafter
specified at any time on or prior to the Closing Date or on or prior to any
later date on which Option Shares are to be purchased, as the case may be, (i)
if the Company or the Selling Stockholder shall have failed, refused or been
unable to perform any agreement on its part to be performed, or because any
other condition of the Underwriters' obligations hereunder required to be
fulfilled is not fulfilled, including, without limitation, any change in the
condition (financial or otherwise), earnings, operations, business or business
prospects of the Company and its subsidiaries considered as one enterprise from
that set forth in the Registration Statement or Prospectus, which, in your sole
judgment, is material and adverse, or (ii) if additional material governmental
restrictions, not in force and effect on the date hereof, shall have been
imposed upon trading in securities generally or minimum or maximum prices shall
have been generally established on the New York Stock Exchange or on the
American Stock Exchange or in the over the counter market by the NASD, or
trading in securities generally shall have been suspended on either such
exchange or in the over the counter market by the NASD, or if a banking
moratorium shall have been declared by federal, New York or California
authorities, or (iii) if the Company shall have sustained a loss by strike,
fire, flood, earthquake, accident or other calamity of such character as to
interfere materially with the conduct of the business and operations of the
Company regardless of whether or not such loss shall have been insured, or (iv)
if there shall have been a material adverse change in the general political or
economic conditions or financial markets as in your reasonable judgment makes it
inadvisable or impracticable to proceed with the offering, sale and delivery of
the Shares, or (v) if there shall have been an outbreak or escalation of
hostilities or of any other insurrection or armed conflict or the declaration by
the United States of a national emergency which, in the reasonable opinion of
the Representatives, makes it impracticable or inadvisable to proceed with the
public offering of the Shares as contemplated by the Prospectus. In the event of
termination pursuant to subparagraph (i) above, the Company shall remain
obligated to pay costs and expenses pursuant to Sections 4(i), 5 and 8 hereof.
Any termination pursuant to any of subparagraphs (ii) through (v) above shall be
without liability of any party to any other party except as provided in Sections
5 and 8 hereof.

authorized to provide for the issuance of all or any shares of the Preferred

     FIFTH:  The following provisions are inserted for the management of the
     -----                                                                  
business and the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

          (a) The business and affairs of the Corporation shall be managed by or
under the direction of the Board of Directors.

          (b) The number of directors of the Corporation shall be as from time
to time fixed by, or in the manner provided in, the By-Laws of the Corporation.
Election of directors need not be by written ballot unless the By-Laws so
provide.

          (c) A director shall hold office until the annual meeting for the year
in which his or her term expires and until his or her successor shall be elected
and shall qualify, subject, however, to prior death, resignation, retirement,

<PAGE>
 
          (d) Subject to the terms of any one or more classes or series of
Preferred Stock, any vacancy on the Board of Directors that results from an
increase in the number of directors may be filled by a majority of the Board of
Directors then in office, provided that a quorum is present, and any other
vacancy occurring on the Board of Directors may be filled by a majority of the
Board of Directors then in office, even if less than a quorum, or by a sole
remaining director.  Any director elected to fill a vacancy not resulting from
an increase in the number of directors shall have the same remaining term as
that of his predecessor.  Subject to the rights, if any, of the holders of
shares of Preferred Stock then outstanding, any or all of the directors of the
Corporation may be removed from office at any time, but only for cause and only
by the affirmative vote of the holders of at least a majority of the voting
power of the Corporation's then outstanding capital stock entitled to vote
generally in the election of directors.  Notwithstanding the foregoing, whenever
the holders of any one or more classes or series of Preferred Stock issued by
the Corporation shall have the right, voting separately by class or series, to
elect directors at an annual or special meeting of stockholders, the election,
term of office, filling of vacancies and other features of such directorships
shall be governed by the

<PAGE>
 
terms of this Amended and Restated Certificate of Incorporation applicable
thereto, and such directors so elected shall not be divided into classes
pursuant to this Article FIFTH unless expressly provided by such terms.

          (e) In addition to the powers and authority hereinbefore or by statute
expressly conferred upon them, the directors are hereby empowered to exercise
all such powers and do all such acts and things as may be exercised or done by
the Corporation, subject, nevertheless, to the provisions of the GCL, this
Amended and Restated Certificate of Incorporation, and any By-Laws adopted by
the stockholders; provided, however, that no By-Laws hereafter adopted by the
                  --------  -------                                          
stockholders shall invalidate any prior act of the directors which would have
been valid if such By-Laws had not been adopted.

     SIXTH:  No director shall be personally liable to the Corporation or any of
     -----

director, except to the extent such exemption from liability or limitation
thereof is not permitted under the GCL as the same exists or may hereafter be
amended.  If the GCL is amended hereafter to authorize the further elimination
or limitation of the liability of directors, then the liability of a director of
the 

                                       15

Corporation shall be eliminated or limited to the fullest extent authorized by
the GCL, as so amended. Any repeal or modification of this Article SIXTH by the

or modification with respect to acts or omissions occurring prior to such repeal
or modification.

     SEVENTH:  The Corporation shall indemnify its directors and officers to the
     -------                                                                    
fullest extent authorized or permitted by law, as now or hereafter in effect,
and such right to indemnification shall continue as to a person who has ceased
to be a director or officer of the Corporation and shall inure to the benefit of
his or her heirs, executors and personal and legal representatives; provided,
                                                                    --------

          The rights to indemnification and to the advancement of expenses
conferred in this Article SEVENTH shall not be exclusive of any other right
which any person may have or hereafter acquire under this Amended and Restated
Certificate of Incorporation, the By-Laws of the Corporation, any statute,
agreement, vote of stockholders or disinterested directors or otherwise.

          Any repeal or modification of this Article SEVENTH by the stockholders
of the Corporation shall not adversely affect any rights to indemnification
and to the advancement of expenses of a director or officer of the Corporation
existing at the time of such repeal or modification with respect to any acts or
omissions occurring prior to such repeal or modification.

          ---------   -----------------                                       
election of directors or for any other purpose shall be held at such time and
place, either within or without the State of Delaware, as shall be designated
from time to time by the Board of Directors and stated in the notice of the
meeting or in a duly executed waiver of notice thereof.

          Section 2.  Annual Meetings.  The annual meetings of stockholders 
          ---------   ---------------
shall be held on such date and at such time as shall be designated from time to
time by the Board of Directors and stated in the notice of the meeting, at which
meetings the stockholders shall elect directors, and transact such other
business as may properly be brought before the meeting. Written notice of the
annual meeting stating the place, date and hour of the meeting shall be given to
each stockholder entitled to vote at such meeting not less than ten nor more
than sixty days before the date of the meeting.

          Section 3.  Special Meetings.  Unless otherwise prescribed by law or 
          ---------   ----------------   
by the certificate of incorporation of the Corporation, as amended and restated
from time to time (the "Certificate of Incorporation"), special meetings of

<PAGE>
 
quest for a special meeting of the stockholders shall state the purpose or
purposes of the proposed meeting, and at the special meeting, only such business
shall be conducted as shall be specified in the notice of meeting (or any
supplement thereto) given by or at the direction of the Board of Directors.
Written notice of a special meeting stating the place, date and hour of the

          Section 4.  Quorum.  Except as otherwise required by law or by the 
          ---------   ------     
Certificate of Incorporation, the holders of a majority of the capital stock
issued and outstanding and entitled to vote thereat, present in person or
represented by proxy, shall constitute a quorum at all meetings of the
stockholders for the transaction of business. A quorum, once established, shall
not be broken by the withdrawal of enough votes to leave less than a quorum. If,
however, such quorum shall not be present or represented at any meeting of the
stockholders, the stockholders entitled to vote thereat, present in person or
represented by proxy, shall have power to adjourn the meeting from time to time,
without notice other than announcement at the meeting, until a quorum

                                       3
<PAGE>
 
shall be present or represented. At such adjourned meeting at which a quorum
shall be present or represented, any business may be transacted which might have
been transacted at the meeting as originally noticed. If the adjournment is for
more than thirty days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each stockholder entitled to vote at the meeting not less than ten nor more than
sixty days before the date of the meeting.

          Section 5.  Proxies.  Any stockholder entitled to vote may do so in 
          ---------   -------   
person or by his or her proxy appointed by an instrument in writing subscribed
by such stockholder or by his or her attorney thereunto authorized, delivered to
the Secretary of the meeting; provided, however, that no proxy shall be voted or
                              --------  -------                                 
acted upon after three years from its date, unless said proxy provides for a
longer period. Without limiting the manner in which a stockholder may authorize
another person or persons to act for him or her as proxy, either of the
following shall constitute a valid means by which a stockholder may grant such
authority:

               (i)  A stockholder may execute a writing authorizing another
     person or persons to act for him or her as

                                       4
<PAGE>
 
     proxy. Execution may be accomplished by the stockholder or his or her
     authorized officer, director, employee or agent signing such writing or
     causing his or her signature to be affixed to such writing by any
     reasonable means, including, but not limited to, by facsimile signature.

               (ii)  A stockholder may authorize another person or persons to
     act for him or her as proxy by transmitting or authorizing the transmission
     of a telegram or other means of electronic transmission to the person who
     will be the holder of the proxy or to a proxy solicitation firm, proxy
     support service organization or like agent duly authorized by the person
     who will be the holder of the proxy to receive such transmission, provided
     that any such telegram or other means of electronic transmission must
     either set forth or be submitted with information from which it can be
     determined that the telegram or other electronic transmission was
     authorized by the stockholder.

Any copy, facsimile telecommunication or other reliable reproduction of the
writing or transmission authorizing another person or persons to act as proxy

                                       5
<PAGE>
 
for a stockholder may be substituted or used in lieu of the original writing or
transmission for any and all purposes for which the original writing or 
transmission could be used; provided that such copy, facsimile telecommunication
                            --------
or other reproduction shall be a complete reproduction of the entire original
writing or transmission.

          Section 6.  Voting.  At all meetings of the stockholders at which a
          ---------   ------                                                 
quorum is present, except as otherwise required by law, the Certificate of
Incorporation or these By-Laws, any question brought before any meeting of
stockholders shall be decided by the affirmative vote of the holders of a
majority of the total number of votes of the capital stock present in person or
represented by proxy and entitled to vote on such question, voting as a single
class.  The Board of Directors, in its discretion, or the officer of the 
Corporation presiding at a meeting of stockholders, in his or her discretion,
may require that any votes cast at such meeting shall be cast by written ballot.

          Section 7.  Consent of Stockholders in Lieu of Meeting.  Any action
          ---------   ------------------------------------------             
required or permitted to be taken by the stockholders of the Corporation must be
effected at a duly called Annual or Special Meeting of Stockholders of the
Corporation and may not be effected by any consent in writing by such

                                       6
<PAGE>
 
stockholders unless all of the stockholders entitled to vote thereon consent
thereto in writing.

          Section 8.  Nature of Business at Meetings of Stockholders.  No
          ---------   ----------------------------------------------     
business may be transacted at an annual meeting of stockholders, other than
business that is either (a) specified in the notice of meeting (or any
supplement thereto) given by or at the direction of the Board of Directors (or
any duly authorized committee thereof), (b) otherwise properly brought before
the annual meeting by or at the direction of the Board of Directors (or any duly
authorized committee thereof) or (c) otherwise properly brought before the
annual meeting by any stockholder of the Company who is a record or beneficial
owner of shares on the record date for the determination of stockholders
entitled to vote at such annual meeting.  If the Chairman of an annual meeting
determines that business was not properly brought before the annual meeting in
accordance with this section 8, the Chairman shall declare to the meeting that
the business was not properly brought before the meeting and such business shall
not be transacted.

          Section 9.  List of Stockholders Entitled to Vote.  The officer of
          ---------   -------------------------------------                 
the Corporation who has charge of the stock ledger of the Corporation shall

                                       7
<PAGE>
 
prepare and make, at least ten days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten days prior to the
meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder of the Corporation who is
present.

          Section 10.  Stock Ledger.  The stock ledger of the Corporation shall
          ----------   ------------                                            
be the only evidence as to who are the stockholders entitled to examine the
stock ledger, the list required by Section 9 of this Article II or the books of
the Corporation, or to vote in person or by proxy at any meeting of
stockholders.

          Section 11.  Record Date.
          ----------   ----------- 

                                       8

          (a)  In order that the Corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights in
respect of any change, conversion or exchange of stock, or for the purpose of
any other lawful action, the Board of Directors may fix a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted by the Board of Directors and which record date: (1) in
the case of determination of stockholders entitled to vote at any meeting of
stockholders or adjournment thereof, shall not be more than sixty nor less than
ten days before the date of such meeting; and (2) in the case of any other
action, shall not be more than sixty days prior to such other action. If no
record date is fixed: (1) the record date for determining stockholders entitled
to notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held; and (2) the record date for determining stockholders
for any other purpose shall be at the close of business on the day on which the
Board of

                                       9
<PAGE>
 
Directors adopts the resolution relating thereto. A determination of
stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
                                                            --------  -------
that the Board of Directors may fix a new record date for the adjourned meeting.

          (b)  In order that the Corporation may determine the stockholders
entitled to consent to corporate action in writing without a meeting, the Board
of Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board of
Directors, and which record date shall not be more than ten days after the date
upon which the resolution fixing the record date is adopted by the Board of
Directors.  If no record date has been fixed by the Board of Directors, the
record date for determining stockholders entitled to consent to corporate action
in writing without a meeting, when no prior action by the Board of Directors is
required by law, shall be the first date on which a signed written consent
setting forth the action taken or proposed to be taken is delivered to the
Corporation by delivery to its registered office in the State of Delaware, its
principal place of business, or an officer or agent of the Corporation having
custody of the book in which proceedings of meetings of stockholders are

                                      10
<PAGE>
 
recorded. Delivery made to a corporation's registered office shall be by hand or
by certified or registered mail, return receipt requested. If no record date has
been fixed by the Board of Directors and prior action by the Board of Directors
is required by law, the record date for determining stockholders entitled to
consent to corporate action in writing without a meeting shall be at the close
of business on the day on which the Board of Directors adopts the resolutions
taking such prior action.

          Section 12.  Inspectors of Election.  In advance of any meeting of
          ----------   ----------------------                               
stockholders, the Board by resolution or the Chairman or President shall appoint
one or more inspectors of election to act at the meeting and make a written
report thereof. One or more other persons may be designated as alternate
inspectors to replace any inspector who fails to act.  If no inspector or
alternate is present, ready and willing to act at a meeting of stockholders, the
Chairman of the meeting shall appoint one or more inspectors to act at the
meeting.  Unless otherwise required by law, inspectors may be officers,
employees or agents of the Corporation.  Each inspector, before entering upon
the discharge of his or her duties, shall take and sign an oath faithfully to
execute the duties of inspector with strict impartiality and according to the
best of his or her ability.  The inspector shall have the duties prescribed by
law and shall 

                                      11
<PAGE>
 
take charge of the polls and, when the vote is completed, shall make a
certificate of the result of the vote taken and of such other facts as may be
required by law.

          Section 13.  Conduct of Meetings.  The Board of Directors of the
          ----------   -------------------                                
Corporation may adopt by resolution such rules and regulations for the conduct
of the meeting of the stockholders as it shall deem appropriate. Except to the
extent inconsistent with such rules and regulations as adopted by the Board of
Directors, the chairman of any meeting of the stockholders shall have the right
and authority to prescribe such rules, regulations and procedures and to do all
such acts as, in the judgment of such chairman, are appropriate for the proper
conduct of the meeting.  Such rules, regulations or procedures, whether adopted
by the Board of Directors or prescribed by the chairman of the meeting, may
include, without limitation, the following:  (i) the establishment of an
agenda or order of business for the meeting; (ii) the determination of when the
polls shall open and close for any given matter to be voted on at the meeting;
(iii) rules and procedures for maintaining order at the meeting and the safety
of those present; (iv) limitations on attendance at or participation in the
meeting to stockholders of record of the corporation, their duly authorized and
constituted proxies or such other persons as the chairman of the meeting 

                                      12
<PAGE>
 
shall determine; (v) restrictions on entry to the meeting after the time fixed
for the commencement thereof; and (vi) limitations on the time allotted to
questions or comments by participants.

                                  ARTICLE III

                                   DIRECTORS
                                   ---------

          Section 1.  Number and Election of Directors.   The Board of Directors
          ---------   --------------------------------                          
shall consist of not less than one nor more than [twenty-five] members, the
exact number of which shall initially be fixed by the Incorporator and
thereafter from time to time by the Board of Directors.  Except as provided in
Section 3 of this Article III, directors shall be elected by a plurality of the
votes cast at the Annual Meetings of Stockholders and each director so elected
shall hold office until the next Annual Meeting of Stockholders and until such
director's successor is duly elected and qualified, or until such director's
earlier death, resignation or removal.  Any director may resign at any time upon
written notice to the Corporation.  Directors need not be stockholders.

          Section 2.  Nomination of Directors.  Only persons who are nominated 
          ---------   -----------------------   
in accordance with the following procedures shall be eligible for 

                                      13
<PAGE>
 
election as directors of the Company, except as may be otherwise provided in the
Certificate of Incorporation with respect to the right of holders of preferred
stock of the Corporation to nominate and elect a specified number of directors
in certain circumstances. Nominations of persons for election to the Board of
Directors may be made at any annual meeting of stockholders, or at any special
meeting of stockholders called for the purpose of electing directors, (a) by or
at the direction of the Board of Directors (or any duly authorized committee
thereof) or (b) by any stockholder of the Company who is a record or beneficial
owner of shares on the record date for the determination of stockholders
entitled to vote at such meeting.

          No person shall be eligible for election as a director of the Company
 unless nominated in accordance with this Section 2. If the Chairman of the
 meeting determines that a nomination was not made in accordance with this
 Section 2, the Chairman shall declare to the meeting that the nomination was
 defective and such defective nomination shall be disregarded.

          Section 3.  Vacancies.  Subject to the terms of any one or more 
          ---------   ---------   
classes or series of preferred stock, any vacancy on the Board of Directors that
results from an increase in the number of directors may be filled by a majority

                                      14
<PAGE>
 
of the directors then in office, provided that a quorum is present, and any
other vacancy occurring on the Board of Directors may be filled by a majority of
the Board of Directors then in office, even if less than a quorum, or by a sole
remaining director. Notwithstanding the foregoing, whenever the holders of any
one or more class or classes or series of preferred stock of the Corporation
shall have the right, voting separately as a class, to elect directors at an
annual or special meeting of stockholders, the election, term of office, filling
of vacancies and other features of such directorships shall be governed by the
Certificate of Incorporation.

          Section 4.  Duties and Powers.  The business of the Corporation shall 
          ---------   -----------------   
be managed by or under the direction of the Board of Directors which may
exercise all such powers of the Corporation and do all such lawful acts and
things as are not by statute or by the Certificate of Incorporation or by these
By-Laws required to be exercised or done by the stockholders.

          Section 5.  Organization.  At each meeting of the Board of Directors, 
          ---------   ------------   
the Chairman of the Board of Directors, or, in his or her absence, a director
chosen by a majority of the directors present, shall act as Chairman. The
Secretary of the Corporation shall act as Secretary at each meeting of the

                                      15
<PAGE>
 
Board of Directors. In case the Secretary shall be absent from any meeting of
the Board of Directors, an Assistant Secretary shall perform the duties of
Secretary at such meeting; and in the absence from any such meeting of the
Secretary and all the Assistant Secretaries, the Chairman of the meeting may
appoint any person to act as Secretary of the meeting.

          Section 6.  Resignations and Removals of Directors.  Any director of 
          ---------   --------------------------------------            
the Corporation may resign at any time, by giving written notice to the Chairman
of the Board of Directors, the President or the Secretary of the Corporation.
Such resignation shall take effect at the time therein specified or, if no time
is specified, immediately; and, unless otherwise specified in such notice, the
acceptance of such resignation shall not be necessary to make it effective.
Except as otherwise required by law and subject to the rights, if any, of the
holders of shares of preferred stock then outstanding, any director or the
entire Board of Directors may be removed from office at any time, but only for
cause, and only by the affirmative vote of the holders of at least a majority in
voting power of the issued and outstanding capital stock of the Corporation
entitled to vote in the election of directors.

          ---------   --------                                          
hold meetings, both regular and special, either within or without the State of
Delaware. Regular meetings of the Board of Directors may be held at such time
and at such place as may from time to time be determined by the Board of
Directors and, unless required by resolution of the Board of Directors, without
notice. Special meetings of the Board of Directors may be called by the Chief
Executive Officer or a majority of the directors then in office. Notice thereof
stating the place, date and hour of the meeting shall be given to each director
either by mail not less than forty-eight (48) hours before the date of the

another corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such action, suit or proceeding if such person acted in good
faith and in a manner such person reasonably believed to be in or not opposed to
the best interests of the Corporation, and, with respect to any criminal action
or proceeding, such person had no reasonable cause to believe his or her conduct
was unlawful. The termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that such person did not
act in good faith and in a manner which such person reasonably believed to be in
or not opposed to the best interests of the Corporation, and, 

                                      36
<PAGE>
 
with respect to any criminal action or proceeding, had reasonable cause to
believe that his or her conduct was unlawful.

          Section 2.  Power to Indemnify in Actions, Suits or Proceedings by 
          ---------   ------------------------------------------------------
or in the Right of the Corporation.  Subject to Section 3 of this Article VIII,
- ----------------------------------                                             
the Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that such person is or was a director or officer of the
Corporation, or is or was a director or officer of the Corporation serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise, against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection with the defense or settlement
of such action or suit if such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of the
Corporation; except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the Corporation unless and only to the extent that the Court of
Chancery or 

                                      37
<PAGE>
 
the court in which such action or suit was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

          Section 3.  Authorization of Indemnification.  Any indemnification 
          ---------   --------------------------------                         
under this Article VIII (unless ordered by a court) shall be made by the
Corporation only as authorized in the specific case upon a determination that
indemnification of the director or officer is proper in the circumstances
because such person has met the applicable standard of conduct set forth in
Section 1 or Section 2 of this Article VIII, as the case may be. Such
determination shall be made, with respect to a person who is a director or
officer at the time of such determination, (i) by a majority vote of the
directors who are not parties to such action, suit or proceeding, even though
less than a quorum, or (ii) by a committee of such directors designated by a
majority vote of such directors, even though less than a quorum, or (iii) if
there are no such directors, or if such directors so direct, by independent
legal counsel in a written opinion or (iv) by the stockholders. Such
determination shall be made, with 

                                      38
<PAGE>
 
respect to former directors and officers, by any person or persons having the
authority to act on the matter on behalf of the Corporation. To the extent,
however, that a present or former director or officer of the Corporation has
been successful on the merits or otherwise in defense of any action, suit or
proceeding described above, or in defense of any claim, issue or matter 
therein, such person shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by such person in connection therewith,
without the necessity of authorization in the specific case.

          Section 4.  Good Faith Defined.  For purposes of any determination 
          ---------   ------------------                                       
under Section 3 of this Article VIII, a person shall be deemed to have acted in
good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the Corporation, or, with respect to any
criminal action or proceeding, to have had no reasonable cause to believe his or
her conduct was unlawful, if such person's action is based on the records or
books of account of the Corporation or another enterprise, or on information
supplied to such person by the officers of the Corporation or another enterprise
in the course of their duties, or on the advice of legal counsel for the
Corporation or another enterprise or on information or records given or reports
made 

                                      39
<PAGE>
 
to the Corporation or another enterprise by an independent certified public
accountant or by an appraiser or other expert selected with reasonable care by
the Corporation or another enterprise. The term "another enterprise" as used in
this Section 4 shall mean any other corporation or any partnership, joint
venture, trust, employee benefit plan or other enterprise of which such person
is or was serving at the request of the Corporation as a director, officer,
employee or agent. The provisions of this Section 4 shall not be deemed to be
exclusive or to limit in any way the circumstances in which a person may be
deemed to have met the applicable standard of conduct set forth in Section 1 or
2 of this Article VIII, as the case may be.

          Section 5.  Indemnification by a Court.  Notwithstanding any contrary
          ---------   --------------------------                               
determination in the specific case under Section 3 of this Article VIII, and
notwithstanding the absence of any determination thereunder, any director or
officer may apply to the Court of Chancery of the State of Delaware for
indemnification to the extent otherwise permissible under Sections 1 and 2 of
this Article VIII. The basis of such indemnification by a court shall be a
determination by such court that indemnification of the director or officer is
proper in the circumstances because such person has met the applicable 

                                      40
<PAGE>
 
standards of conduct set forth in Section 1 or 2 of this Article VIII, as the
case may be. Neither a contrary determination in the specific case under Section
3 of this Article VIII nor the absence of any determination thereunder shall be
a defense to such application or create a presumption that the director or
officer seeking indemnification has not met any applicable standard of conduct.
Notice of any application for indemnification pursuant to this Section 5 shall
be given to the Corporation promptly upon the filing of such application.
If successful, in whole or in part, the director or officer seeking
indemnification shall also be entitled to be paid the expense of prosecuting
such application.

          Section 6.  Expenses Payable in Advance.  Expenses incurred by a 
          ---------   ---------------------------                              
director or officer in defending or investigating a threatened or pending
action, suit or proceeding shall be paid by the Corporation in advance of the
final disposition of such action, suit or proceeding upon receipt of an 
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that such person is not entitled to be
indemnified by the Corporation as authorized in this Article VIII.

          Section 7.  Nonexclusivity of Indemnification and Advancement of
          ---------   ----------------------------------------------------
Expenses.  The indemnification and advancement of expenses provided by or
- --------                                                                  
granted pursuant to this Article VIII shall not be deemed exclusive of any other
rights to which those seeking indemnification or advancement of expenses may be
entitled under the Certificate of Incorporation or any By-Law, agreement,
contract, vote of stockholders or disinterested directors or pursuant to the
direction (howsoever embodied) of any court of competent jurisdiction or
otherwise, both as to action in such person's official capacity and as to action
in another capacity while holding such office, it being the policy of the
Corporation that indemnification of the persons specified in Section 1 and 2 of
this Article VIII shall be made to the fullest extent permitted by law.  The
provisions of this Article VIII shall not be deemed to preclude the
indemnification of any person who is not specified in Section 1 or 2 of this
Article VIII but whom the Corporation has the power or obligation to indemnify
under the provisions of the GCL, or otherwise.

          Section 8.  Insurance.  The Corporation may purchase and maintain
          ---------   ---------                                            
insurance on behalf of any person who is or was a director or officer of the
Corporation, or is or was a director or officer of the Corporation serving at
the 

                                      42
<PAGE>
 
request of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise against any liability asserted against such person and incurred by
such person in any such capacity, or arising out of such person's status as
such, whether or not the Corporation would have the power or the obligation to
indemnify such person against such liability under the provisions of this
Article VIII.

          Section 9.  Certain Definitions.  For purposes of this Article VIII,
          ---------   -------------------                                     
references to "the Corporation" shall include, in addition to the resulting
corporation, any constituent corporation (including any constituent of a
constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors or officers, so that any person who is or was a director or officer of
such constituent corporation, or is or was a director or officer of such
constituent corporation serving at the request of such constituent corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise, shall stand in
the same position under the provisions of this Article VIII with respect to the

                                      43
<PAGE>
 
resulting or surviving corporation as such person would have with respect to
such constituent corporation if its separate existence had continued. For
purposes of this Article VIII, references to "fines" shall include any excise
taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the Corporation" shall include any
service as a director, officer, employee or agent of the Corporation which
imposes duties on, or involves services by, such director or officer with
respect to an employee benefit plan, its participants or beneficiaries; and a
person who acted in good faith and in a manner such person reasonably believed
to be in the interest of the participants and beneficiaries of an employee
benefit plan shall be deemed to have acted in a manner "not opposed to the best
interests of the Corporation" as referred to in this Article VIII.

          Section 10.  Survival of Indemnification and Advancement of Expenses.
          ----------   -------------------------------------------------------  
The indemnification and advancement of expenses provided by, or granted pursuant
to, this Article VIII shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director or officer and
shall inure to the benefit of the heirs, executors and administrators of such
a person.

          Section 11.  Limitation on Indemnification.  Notwithstanding anything
          ----------   -----------------------------                           
contained in this Article VIII to the contrary, except for proceedings to
enforce rights to indemnification (which shall be governed by Section 5 hereof),
the Corporation shall not be obligated to indemnify any director or officer (or
his or her heirs, executors or personal or legal representatives) or advance
expenses in connection with a proceeding (or part thereof) initiated by such
person unless such proceeding (or part thereof) was authorized or consented to
by the Board of Directors of the Corporation.

          Section 12.  Indemnification of Employees and Agents.  The Corporation
          ----------   ---------------------------------------

Article VIII to directors and officers of the Corporation.

the stockholders or by the Board of Directors, provided, however, that notice of

Ladies and Gentlemen:

          We have acted as special counsel to Knight/Trimark Group, Inc., a
Delaware corporation (the "Company"), in connection with the initial public
offering (the "IPO") by the Company of up to 10,188,246 shares (including
1,500,000 shares subject to an over-allotment option) (the "Company Shares") and
the sale by Gruntal & Co., L.L.C., as selling stockholder (the "Selling
Stockholder") of 1,311,754 shares (the "Selling Stockholder Shares", and
together with the Company Shares, the "Shares") of the Company's Common Stock,
par value $0.01 per share (the "Com  mon Stock").

          Each of the members of Roundtable Partners, L.L.C. (the "LLC"),
including the Selling Stockholder, entered into a contribution agreement (the
"Contribution Agreement"), dated April 18, 1998, by and among the LLC, the
Company and the members of the LLC, pursuant to which such members agreed to
contribute all of their interests in the LLC to the Company, concurrently with
the closing of the IPO, in exchange for shares of Common Stock. Pursuant to a
letter agreement, dated April 29, 1998 (the "Gruntal Letter Agreement"), the
Company has agreed to allow the Selling Stockholder to sell in the IPO all of
the shares of Common Stock it will acquire pursuant to the Contribution
Agreement.

               Accounts"), but only insofar as such orders are transmitted by
               the Correspondent or its designee to CSC.

     (ii)      CSC will generate, prepare and/or transmit the appropriate data
               to effect the production of and cause to be mailed confirmations
               respecting transactions effected by each of the Introduced
               Accounts.

     (iii)     CSC will prepare and mail the summary monthly statements (or
               quarterly statements if no activity in any Introduced Account

               herein shall cause the Correspondent's customers to be construed
               or interpreted as customers of CSC for any other purpose, or to
               negate the intent of any other section of this agreement,
               including, but not limited to, the delineation of
               responsibilities as set forth elsewhere in this agreement. Upon

               transactions executed or cleared through it and not specifically
               charged to the Correspondent pursuant to the terms of this
               Agreement, including a daily record of required margin and other
               information required by Rule 432(a) of the rules of the Board of
               Directors of the New York Stock Exchange, Inc. (the "Rules"), or
               by the constitution, articles of incorporation, by-laws (or
               comparable instruments) or rules, regulations or other
               instruments corresponding to the foregoing, and the stated

               of 1934, as amended ("National Securities Exchange").

               Correspondent with any necessary information and data contained
               in books and records kept by CSC and not otherwise reasonably

     See Schedule "A" attached hereto and incorporated herein by reference.

     Correspondent shall have sole discretion to determine the amount of
     commission/mark up and/or fees charged to its Introduced Accounts cleared
     by CSC. CSC agrees to pay

                                       3
<PAGE>
 
     Correspondent all commissions and/or sales credits received by CSC with
     respect to business introduced by Correspondent less any amounts due to CSC
     under this Agreement or otherwise and any expenses or other sums paid to
     third parties by CSC paid on the Correspondent's behalf.

     In no event shall the fees charged in this Article II for the above
     services be in contravention of the Securities Act of 1933, as amended, the
     Securities Exchange Act of 1934, the Investment Advisers Act of 1940, as
     amended, or the Employee Retirement Income Security Act of 1974, as
     amended, or any rules or regulations thereunder, or any other law, rule or
     regulation, Federal, State or Local, or any constitution, by-law, rule,
     regulation or instrument correspondent to the foregoing, or stated policy
     or practice of any national securities exchange or other securities
     exchange or association or other regulatory or self-regulatory body or
     agency ("Laws and Regulations"). In the event that such fees are deemed by
     CSC or the Correspondent to be in contravention of the Laws and
     Regulations, they shall be replaced with fees mutually agreed upon in
     writing by CSC and the Correspondent.

III. Notation on Statements, Confirmation and Other Written Material
     ---------------------------------------------------------------

     CSC shall carry all Introduced Accounts in the names of the Correspondent's
     customers, with a notation on its books and records that such Introduced
     Accounts were introduced by the Correspondent, and all monthly or quarterly
     statements and confirmations relating to such Introduced Accounts shall
     also indicate that the Introduced Accounts were introduced by the
     Correspondent. In addition, account statements will indicate that customer
     funds and securities received by CSC will be held at CSC and will contain
     the telephone number of a contact area at CSC. Inadvertent omission of such
     notations shall not be deemed to constitute a breach of this Agreement.
     Copies of the forms covering the foregoing shall be furnished by CSC to the
     Correspondent.

IV.  Opening of Accounts
     -------------------

     (i)       At the time of the opening of each Introduced Account,
               Correspondent shall furnish CSC with all financial and personal
               information concerning such Introduced Accounts as CSC may
               reasonably require. At the time of the opening of any Introduced
               Accounts which are margin accounts, the Correspondent shall
               furnish CSC with executed customers' agreements, hypothecation
               agreements and consents to loans of securities (collectively, the
               "margin agreement"). CSC shall supply the Correspondent with
               margin agreement forms regarding margin accounts in sufficient
               quantities, such forms to be submitted to CSC upon their
               completion by the correspondent. If any Introduced Account may
               have been opened without CSC having previously received a
               properly executed margin agreement, failure of CSC to receive
               such margin agreements shall not be deemed to be a waiver of the
               information requirements set forth herein. Upon the written or
               oral

                                       4
<PAGE>
 
               request of CSC, the Correspondent shall furnish CSC with any
               other documents and agreements executed by the Introduced Account
               on forms which shall be supplied by CSC in sufficient quantities
               and which may reasonably be required by CSC in connection with
               the opening, operating or maintaining of any Introduced Account.
               CSC may, at its option, mail margin agreements, option
               agreements, "new account" forms or any other form at its
               discretion directly to the Introduced Accounts upon notification
               of the Correspondent, and/or require completion of said margin
               agreements, "new account" forms and/or other forms, and, if
               required, option account agreements for the Introduced Accounts.
               The Correspondent shall promptly provide CSC with basic data and
               copies of documents relating to each of the Introduced Accounts,
               including, but not otherwise limited to, copies of records of any
               receipts of the Introduced Accounts' funds and/or securities
               received directly by the Correspondent, as shall be necessary for
               CSC to discharge its service obligations hereunder.

     (ii)      All transactions in any Introduced Account are to be considered
               cash transactions until such time as CSC has received margin
               agreements, duly and validly executed in respect of such
               Introduced Account. Nevertheless, it is intended that
               Correspondent will obtain executed margin agreements within the
               time periods set forth in procedural manuals provided by CSC or
               any entity affiliated with CSC. In the event credit is
               inadvertently extended with respect to such Introduced Accounts,
               Correspondent shall indemnify and hold CSC harmless from and
               against all loss, liability, damage, cost and expense (including
               but not otherwise limited to seasonable fees and expenses of
               legal counsel) arising therefrom.

     (iii)     At the time of the opening of any Introduced Account, the
               Correspondent shall furnish CSC with the name of any principal if
               other than the account name, for whom the Correspondent is acting
               as agent, and written evidence of such authority.

     (iv)      The Correspondent shall have the sole and exclusive
               responsibility for compliance with Rule 405(3) of the Rules and
               shall specifically approve the opening of any new account before
               forwarding such account to CSC as a potential Introduced Account.
               CSC, in its reasonable business judgement, reserves the right to
               reject any account which the Correspondent may forward to CSC as
               a potential Introduced Account. CSC also reserves the right to
               terminate any account previously accepted by it as an Introduced
               Account. By mutual agreement, CSC may open institutional accounts
               on behalf of Correspondents, if said institution deals directly
               with CSC or any affiliated organization.

     (v)       Pursuant to written notification received by the Correspondent 
               and

                                       5
<PAGE>
 
               forwarded to CSC, any account of the Correspondent may choose to
               reject the services to be performed by CSC pursuant to this
               Agreement and thus choose not to be serviced as an Introduced
               Account pursuant hereto. Upon notice from another member
               organization that an Introduced Account intends to transfer his
               account thereto, CSC shall expedite such transfer and shall have
               the sole and exclusive responsibility for compliance with Rule
               412 of the Rules.

     (vi)      It shall be the sole and exclusive responsibility of the
               Correspondent to make every reasonable effort to ascertain the
               essential facts relative to any Introduced Account and any order
               therefore, in compliance with Rule 405(1) of the Rules, including
               but not otherwise limited to ascertaining the authority of all
               orders for Introduced Accounts, and the genuineness of
               certificates, papers and signatures provided by each Introduced
               Account. Any investment advice to include selection of a
               qualified money manager furnished to an Introduced Account by the
               Correspondent shall be the sole and exclusive responsibility of
               the Correspondent.

     (vii)     The Correspondent shall be solely and exclusively responsible for
               the handling and supervisory review of any Introduced Accounts
               over which the Correspondent's partners, officers or employees
               have discretionary authority, as required by Rule 408 of the
               Rules and any other applicable Laws and Regulations. The
               Correspondent shall furnish CSC with such documentation with
               respect thereto as may be requested by CSC. The Correspondent
               hereby agrees to indemnify and hold CSC harmless against any
               loss, liability, damage, cost or expense (including but not
               otherwise limited to fees and expenses of legal counsel) suffered
               or incurred by CSC directly or indirectly as a result of any
               liabilities or claims arising from the exercise by the
               Correspondent, its partners, officers or employees of
               discretionary authority over Introduced Accounts. The
               Correspondent hereby warrants that with regard to any orders or
               instructions given by the Correspondent with respect to such
               discretionary accounts, its partners, officers or employees shall
               have been fully and properly authorized relative thereto and that
               the execution of such orders shall not be in violation of the
               Laws and Regulations. Furthermore, the Correspondent hereby
               agrees to indemnify and hold CSC harmless against any loss,
               liability, damage, cost or expense (including but not otherwise
               limited to fees and expenses of legal counsel) suffered or
               incurred by CSC directly or indirectly as a result of any breach
               of the Correspondent's said warranty.

     (viii)    The Correspondent shall have the sole and exclusive
               responsibility for the handling and supervisory review of any
               Introduced Account for an employee or officer of any member
               organization, self-regulatory organization, bank, trust company,
               insurance company or other

                                       6
<PAGE>
 
               organization engaged in the securities business, and for
               compliance with Rule 407 of the Rules relating thereto. The
               Correspondent shall furnish CSC with such documentation with
               respect thereto as may be requested by CSC.

     (xi)      The Correspondent shall have the sole and exclusive
               responsibility to insure that those of its customers who become
               Introduced Accounts hereunder shall not be minors or subject to
               those prohibitions existing under the Laws and Regulations
               generally relating to the incapacity of any Introduced Account or
               any conflict of interest relating to such Introduced Account.

     (x)       The Correspondent shall be solely and exclusively responsible for
               any loss, liability, damage, cost or expense (including but not
               otherwise limited to fees and expenses of legal counsel)
               sustained or incurred by either itself or CSC, arising out of or
               resulting from any orders the Correspondent has taken from an
               Introduced Account residing or being domiciled in jurisdictions
               in which the Correspondent has not been or is no longer
               authorized to do business.

     (xi)      It shall be the sole and exclusive responsibility of the
               Correspondent to comply with the Laws and Regulations relating to
               each Introduced Account which effect listed option transactions
               including, but not limited to, approval by the Correspondent's
               Registered Options Principal or Senior Registered Options
               Principal (as applicable), delivery of required Options
               Disclosure Documents (and Supplements where applicable) and
               option documentation.

V.   Transactions and Margin
     -----------------------
     
     (i)       It is understood that with respect to Introduced Accounts which
               are margin accounts, CSC is responsible for compliance with
               Regulation T, 12 C.F.R. Part 220, the Federal margin regulation
               promulgated by the Board of Governors of the Federal Reserve
               System (the "Board"), and any interpretative ruling issued by the
               Board, and letter rulings of the Federal Reserve Bank of New
               York, Rules and Interpretations of the New York Stock Exchange,
               Inc. and any other applicable margin and margin maintenance
               requirements of the Laws and Regulations. The Correspondent is
               responsible to CSC for the collection of the margin required to
               support each transaction, and to maintain the proper margin in
               each Introduced Account and to insure that such margin is in
               conformity with the above margin and margin maintenance
               requirements. After such initial margin on each transaction has
               been received, maintenance margin calls shall be generated by CSC
               and made by CSC or by the

                                       7
<PAGE>
 
                    Correspondent at the instructions of CSC. CSC shall have the
                    right to modify, in its sole discretion, the margin
                    requirements of any Introduced Account from time to time so
                    that CSC may call for additional margin. Therefore, CSC
                    shall be the sole judge as to the amount of margin to be
                    required of and maintained by Introduced Accounts. CSC may
                    impose such margin by individual security, by individual
                    Correspondent fusion or by a specified Introduced Account
                    and such margin need not be of general application to all
                    accounts.

          (ii)      On all transactions, the Correspondent shall be solely and
                    exclusively responsible to CSC for any loss, liability,
                    damage, cost or expense (including but not otherwise limited
                    to fees and expenses of legal counsel) incurred or sustained
                    by the Correspondent or CSC as result of the failure of any
                    Introduced Account to make timely payment for the securities
                    purchased by it or timely and good delivery of securities
                    sold for it, or timely compliance by it with margin or
                    margin maintenance calls (provided that CSC has timely
                    issued such call and/or given notice thereof to the
                    Correspondent or if conditions creating such call should be
                    reasonably known by Correspondent), whether or not any cash
                    and/or margin extensions have been granted by CSC pursuant
                    to the request of the Correspondent. Interest will be
                    charged by CSC for cash debits in cash accounts past
                    settlement date and/or margin debits in all Introduced
                    Accounts. The Correspondent agrees to be solely and
                    exclusively responsible for the payment and delivery of all
                    "when issued" or "when distributed" transactions which CSC
                    may accept, forward or execute for Introduced Accounts.

          (iii)     On all over-the-counter transactions for Introduced
                    Accounts, the Correspondent shall furnish CSC with the names
                    of the respective purchasing and selling (contra) broker-
                    dealers) except as otherwise provided in paragraph (iv) of
                    this Section, as set forth below), the names of the
                    purchasing and selling customers, the wholesale and retail
                    purchase/sale prices and mark-ups/mark-downs.

          (iv)      Should the Correspondent entrust the execution of an order
                    in an over-the-counter security to CSC or any entity
                    affiliated with CSC and the counter party is left at CSC's
                    discretion, CSC will assume the responsibility of paying the
                    Correspondent that which the counter party has failed to pay
                    pursuant to the over-the-counter order transaction (counter
                    party risk). In the case the Correspondent executes its own
                    over-the-counter order or designates the counter party, it
                    shall be understood that in the event the over-the-counter
                    dealer with whom the Correspondent dealt or whom it
                    designated fails to live up to its part of the transaction,
                    the Correspondent will assume the counter party risk and
                    reimburse CSC for any loss

                                       8
<PAGE>
 
               sustained thereby.

     (v)       The Correspondent shall be solely and exclusively responsible for
               all orders placed on behalf of or by the Introduced Accounts. The
               Correspondent is also responsible for establishing procedures to
               insure that such orders are transmitted properly to CSC for
               execution. CSC, in its reasonable business judgement, reserves
               the right to reject any order which the Correspondent or its
               designate may transmit to CSC for execution.

     (vi)      The Correspondent shall be solely and exclusively responsible for
               the supervisory review of all orders for the Introduced Accounts
               and shall insure that any orders and instructions given by it or
               any of its employees to CSC pursuant to the terms of this

               any of its employees, shall be the sole and exclusive
               responsibility and liability of CSC. In the event, however, that
               by reason of such error, misunderstanding or controversy, CSC in
               its discretion deems it advisable to commence an action or
               proceeding against an Introduced Account, CSC shall indemnify and
               hold the Correspondent harmless from any loss, liability, damage,
               cost or expense (including but not otherwise limited to
               reasonable fees and expenses of legal counsel) which the
               Correspondent may incur or sustain in connection therewith or
               under any settlement thereof. If such error, misunderstanding or
               controversy shall result in the bringing of an action or
               proceeding against the Correspondent, CSC shall indemnify and
               hold the Correspondent harmless from any loss, liability, damage,
               cost or expense (including but not otherwise limited to
               reasonable fees and expenses of legal counsel) which the
               Correspondent may incur or sustain in connection therewith or
               under any settlement thereof.

     (iii)     CSC and the Correspondent both agree to indemnify the other and
               hold the other harmless from and against any loss, liability,
               damage, cost or expense (including but not otherwise limited to
               reasonable fees and expenses of legal counsel) arising out of or
               resulting from any failure by the indemnifying party or any of
               its employees to carry out fully the duties and responsibilities
               assigned to the indemnifying party herein or any breach of any
               representation or warranty herein by the indemnifying party under
               this Agreement. The Correspondent hereby agrees to indemnify and
               hold CSC harmless from and against any loss, liability, damage,
               cost or expense (including but not otherwise limited to
               reasonable fees and expenses of legal counsel) sustained or
               incurred in connection herewith in the event any Introduced
               Account fails to fully pay for a cash transaction or to meet any
               initial margin call or subsequent maintenance calls, in
               conformity with Section V hereof.

     (iv)      The indemnification provisions in this Agreement, shall remain
               operative and in full force and effect, regardless of the
               termination of this Agreement, and shall survive any such
               termination.

               benefit of its creditors, or admits in writing its inability to
               pay its debts generally as they become due, or consents to the
               appointment of a receiver, trustee or liquidator of either CSC or
               the Correspondent, or of any property held by either party; or

       may, at its option, by notice to the defaulting party declare that this
       Agreement shall be thereby terminated and such termination shall be

XIII.  Remedies Cumulative
       -------------------  

       The enumeration herein of specific remedies shall not be exclusive of
       any other remedies. Any delay or failure by any party of this Agreement
       to exercise any right, power, remedy or privilege herein contained, or
       now or hereafter existing under any applicable statute or law, shall not
       be construed to be a waiver of such right, power, remedy or privilege or
       to limit the exercise of such right, power, remedy or privilege. No
       single, partial or other exercise of any such right, power, remedy or
       privilege shall preclude the further exercise thereof or the exercise of

XIV.   Miscellaneous
       -------------

       (1)     As of the effective date of this Agreement, CSC will not convert

               customer accounts of the Correspondent that are partially or
               totally unsecured, securities in the name of the Correspondent's
               customers, or legal transfer securities (securities in the name
               of estates, trust, joint ownership, foreign ownership and such),
               unless previously approved in writing by CSC. If in error such
               accounts are converted to CSC books or records, CSC reserves the

               clearing firm said customer accounts and the positions.

               the Correspondent as of the effective date of this Agreement, and
               appropriate adjustments shall be made by CSC to reflect that CSC
               will now act as broker on open orders previously placed with
               specialists on any national securities exchange or other
               securities exchange.

                                      16

     (iii)     CSC shall have the power to effect appropriate adjustments with
               respect to pending dividends and other distributions from the

               such pending dividends.

     (vi)      The Correspondent shall be responsible for providing annual
               dividend and distribution information as contained in IRS Form
               1087 (to include individual 1099 filings) and any other
               information required to be reported by Federal, state or local
               tax laws, rules and regulations, to its customers until the
               effective date of this Agreement, whereupon CSC shall assume this
               function as to Introduced Accounts.

     (v)       CSC shall have the power to allocate and make appropriate

               Introduced Accounts shall be paid within 30 days of their origin
               date, and it shall be the responsibility of the Correspondent to
               collect such payments from its customers and transmit them to CSC
               within such 30-day period. If any unsecured debit balances remain
               outstanding beyond such 30-day period, CSC is authorized to apply
               as payment of such debit balances commission fees owed to the
               Correspondent in connection with transactions pursuant to this
               Agreement.

               itself out as an agent of CSC or any of the subsidiaries or
               companies controlled directly or indirectly by or affiliated with
               CSC or its parent.

     (ix)      This Agreement supersedes any previous agreement and may be
               modified only in writing, signed by both CSC and the
               Correspondent. Such modification shall not be deemed as a
               cancellation of this Agreement.

     (x)       This Agreement shall be submitted to and/or approved by any
               national securities exchange, or other regulatory and self-
               regulatory bodies vested with the authority to review and/or
               approve this Agreement or any amendment or modifications hereto.
               In the event of any such disapproval, the parties hereto agree to
               bargain in good faith to achieve the requisite

                                      17
<PAGE>
 
                    approval. CSC will file a fully executed copy of this
                    agreement with the New York Stock Exchange.

        (xi)        This Agreement may be canceled by either of the parties
                    hereto upon sixty (60) days' written notice; provided,
                    however, that this Agreement may be canceled by either party
                    upon thirty (30) days' written notice if (i) the net
                    capital ratio of the other party exceeds 10 to 1, (ii) if
                    the other party has elected to operate under paragraph [f]
                    of Rule 15c3-1 of the Securities Exchange Act of 1934, as
                    amended, when its net capital is less than 5% of aggregate
                    debit items computed in accordance with Rule 15c3-3, (iii)
                    when the aggregate amount of any withdrawals of equity
                    capital and/or unsecured advances or loans exceed 20% of
                    excess net capital in any 30 day period or 30% of excess net
                    capital in any 90 day period or (iv) its stated net capital
                    is less than the minimum amount required under this
                    Agreement; and provided, further, that this Agreement may be
                    canceled by CSC at any time between the date on which this
                    Agreement is executed and the effective date of this
                    Agreement, if there is a material change in the control or
                    management of the Correspondent.

          (xii)     Any dispute or controversy between the Correspondent and CSC
                    relating to or arising out of this Agreement shall be
                    settled by arbitration before and under the rules of the
                    Arbitration Committee of the New York Stock Exchange, Inc.,
                    unless the transaction which gave rise to such dispute or
                    controversy was effected in another exchange or market which
                    provides arbitration facilities, in which case it shall be
                    settled by arbitration under such facilities.
                    
          (xiii)    CSC will not be bound to make any investigation into the
                    facts surrounding any transaction that it may have with the
                    Correspondent on a principal or agency basis or that the
                    Correspondent may have with its customers or other persons,
                    nor will CSC be under any responsibility for compliance by
                    the Correspondent with any Laws and Regulations which may be
                    applicable to the Correspondent. It is understood that CSC
                    will assist the Correspondent in any investigation conducted
                    by the Correspondent.

          (xiv)     To facilitate the keeping of records by CSC the
                    Correspondent will turn over promptly to CSC any and all
                    cash remittances and securities which the Correspondent
                    receives from its customer. Concurrently with the delivery
                    of such funds or securities to the Correspondent, it shall
                    furnish CSC with such information as may be relevant or
                    necessary to enable CSC to record promptly an properly such
                    cash remittances and securities in the respective Introduced
                    Accounts.

          (xv)      This Agreement shall be binding upon all successors, assigns
                    or transferees of both parties hereto, irrespective of any
                    change with regard to the name of or the personnel of the
                    Correspondent or CSC. Any assignments of this Agreement
                    shall be subject to the requisite review and/or approval of
                    any regulatory or self-regulatory agency or body whose
                    review and/or approval must be obtained prior to the
                    effectiveness and validity of such assignment. Except as
                    indicated below, no assignment of this Agreement by either
                    party shall be valid unless consented to in writing by the
                    other party. Any assignment by CSC to any subsidiary or to a
                    company affiliated with or controlled directly or indirectly
                    by CSC will be deemed valid and enforceable in the absence
                    of any consent from Correspondent. Neither this Agreement
                    nor any operation hereunder is intended to be, shall not be
                    deemed to be, and shall not be treated as a general or
                    limited partnership, association or joint venture or agency
                    relationship between the Correspondent and CSC.

          (xvi)     Should the Correspondent in any way attempt to hold itself
                    out as, advertise or in any way represent that it is the
                    agent of CSC or any affiliated entity, CSC shall have the
                    power, at is option, to terminate the Agreement and the
                    Correspondent shall be liable for any loss, liability,
                    damage, cost or expense (including but not otherwise limited
                    to reasonable fees and expenses of legal counsel) sustained
                    or incurred by CSC as a result of such representation of
                    agency or apparent authority to act as an agent of CSC, or
                    any affiliated entity, or agency by estoppel.

          (xvii)    The Correspondent shall not, without having obtained the
                    prior written approval of CSC, agree to place or place any
                    advertisement in any newspaper, publication, periodical or
                    any other media if such advertisement in any manner makes
                    reference to CSC, to any person or entity that directly, or
                    indirectly through one or more intermediaries, controls or
                    is controlled by, or is under common control with CSC and to
                    the clearing arrangements and/or any of the services
                    embodied in this Agreement.

          (xviii)   The Laws and Regulations require that CSC must have proper
                    documentation to support any account opened on its books,
                    including Introduced Accounts. If, after reasonable requests
                    therefor, the necessary documents so as to enable CSC to
                    comply with such account documentation requirements of the
                    Laws and Regulations have not been received by CSC, the
                    Correspondent shall receive notification that no further
                    orders will be accepted for the Introduced Accounts
                    involved. Should it happen that inadvertent orders are
                    placed for such accounts after this notice is received, no
                    commission credit will be granted from such order. On
                    receipt of the necessary documents, this restriction will be
                    lifted on future commissions, but any commissions withheld
                    will not be credited
                    
                                      19
<PAGE>
 
               or paid. This Agreement is not in any way intended to limit the 
               responsibility of CSC under the Laws and Regulations with respect
               to Introduced Accounts.

     (xix)     The construction and effect of every provision of this Agreement,
               the rights of the parties hereunder and any questions arising out
               of this Agreement, shall be subject to the statutory and common 
               law of the State of New York.

     (xx)      The headings preceding the text, articles and sections hereof 
               have been inserted for convenience and reference only and shall 
               not be construed to affect the meaning, construction or effect of
               this Agreement.

     (xxi)     This Agreement shall cover only the type of services set forth 
               herein and is in no way intended nor shall be construed to bestow
               upon the Correspondent any special treatment regarding any other 
               arrangements, agreements or understandings which presently exist 
               between Correspondent and CSC or which may hereinafter exist. The
               Correspondent shall be under no obligation whatsoever to deal 
               with CSC or any of its subsidiaries or any companies controlled 
               directly or indirectly by or affiliated with CSC or its parent, 
               in any capacity other than as set forth in this Agreement. 
               Likewise, CSC shall be under no obligation whatsoever to deal 
               with the Correspondent or any of its affiliates in any capacity
               other than as set forth in this Agreement.

     (xxii)    If any provision or condition of this Agreement shall be held to 
               be invalid or unenforceable by any court, or regulatory or 
               self-regulatory agency or body, such invalidity or 
               unenforceability shall attach only to such provision or 
               condition. The validity of the remaining provisions and 
               conditions shall not be affected thereby and this Agreement shall
               be carried out as if any such invalid or unenforceable provision
               or condition were not contained herein.

     (xxiii)   In the event that CSC assumes any contractual obligation on 
               behalf of the Correspondent relative to communications equipment,
               the Correspondent hereby agrees to immediately absorb the 
               remaining portion of said contract if Correspondent terminates 
               the relationship with CSC. The Correspondent further agrees to 
               absorb any all costs associated with the removal or relocation of
               any communications equipment installed by or at the direction of
               CSC, if this agreement is terminated by the Correspondent.

     (xxiv)    Any unsecured debit residing in a customer account as a result of
               the failure to perform on behalf of the customer and/or the
               Correspondent will be the responsibility of the Correspondent.
               Thirty (30) calendar days will

                                      20

               be allowed for collection. If funds are not received, CSC
               reserves the right to debit the Correspondent; bad debit,
               collateral and/or commission refund account the amount of the
               unsecured balance plus interest at the rate of 1/2% above the
               prevailing broker call loan rate.

     (xxv)     The interest and handling expense (to include day charges) for
               any DVP transaction that does not settle on a normal or regular
               way basis or is rejected by the agent for any reason other than
               CSC negligence is the responsibility of the Correspondent.

     (xxvi)    For the purposes of any and all notices, consents, directions,
               approvals, restrictions, requests or other communications
               required or permitted to be delivered hereunder, CSC's address
               shall be 1000 Harbor Boulevard, 7th Floor, Building "A",
               Weehawken, New Jersey 07087 and the Correspondent's address shall
               be 525 Washington Blvd, Jersey City, NJ and either party may
               change its address for notice purposes by giving written notice
               pursuant to registered mail of the new address to the other
               party.

     (xxvii)   This Agreement shall become effective on or about 5/5/97 or such

solely by its own gross negligence or willful misconduct. NISC will not be bound
to make any investigation into the facts surrounding any transaction that it may
have with TRIMARK or that TRIMARK may have with or on behalf of other persons,
nor will NISC be responsible for compliance by TRIMARK with the Laws and Rules
in connection with any Account or the performance by TRIMARK of its obligations
under this Agreement. TRIMARK acknowledges and agrees that this Agreement
significantly limits the liability of NISC and that such limitation is fair and
reasonable in light of the limited responsibilities of NISC, and the amounts
payable to NISC for its services, under this Agreement.

     B.  NISC shall use its best efforts to promptly notify TRIMARK of any
systems or communications failures. To the extent that TRIMARK is unaware of any
such systems or communications failures known to NISC, NISC shall be responsible
for any orders accepted from TRIMARK but not transmitted to the appropriate
exchange as a direct result therefrom, except that NISC shall not be responsible
in those circumstances where the appropriate exchange is itself unable to accept
the order flow from NISC. Under no circumstances shall NISC be responsible for
any loss, expense or damage suffered by TRIMARK as a result of any systems or
communications failures after providing notice to TRIMARK of such occurrence. In
any event, whether or not NISC has been advised of or might otherwise have
anticipated the possibility of such damages, NISC will not be responsible for
any indirect or consequential damages which TRIMARK may incur or experience as a
result of the foregoing.

                 --------  -------
bonds, or other securities of any person, firm, corporation or their business

broker-dealer business.

          (iii)     Notwithstanding anything to the contrary contained herein,
the provisions of Section 7(a)(i) shall not apply from and after the Employee's
termination of employment pursuant to Section 5(b) or Section 5(c) above.

     (b) TRADE SECRETS.  The Employee agrees and understands that in the
Employee's position with the Company, the Employee will be exposed to and

                                       7
<PAGE>
 
receive information relating to the confidential affairs of the Company,
including but not limited to business and marketing plans, membership lists,
strategies, customer information, other information concerning the Company's
services, development, financing, expansion plans, business policies and
practices, and other forms of information considered by the Company to be
confidential and in the nature of trade secrets.  The Employee agrees that
during the Employment Term and at all times thereafter the Employee will keep
such information confidential and not disclose such information, either directly
or indirectly, to any third person or entity without the prior written consent
of the Company.  This confidentiality covenant has no temporal, geographical or
territorial restriction.  Upon termination of this Agreement, the Employee will
promptly supply to the Company all property, keys, notes, memoranda, writings,
lists, files, reports, customer lists, correspondence, tapes, disks, cards,
surveys, maps, logs, machines, technical data or any other tangible product or
document which has been produced by, received by or otherwise submitted to the
Employee during or prior to the Employment Term.

     (c) NON-SOLICITATION.  The Employee agrees that (i) if his employment is

any time during his employment or at any time after termination of employment,

publish any statement or make any statement (under circumstances reasonably
likely to become public or that he might reasonably expect to become public)
critical of the Company, or in any way adversely affecting or otherwise
maligning the business or reputation of the Company or any of its affiliates.

     (d) REMEDY.  The Employee further agrees that any breach of the terms of
this Section 7 would result in irreparable injury and damage to the Company for
which the Company would have no adequate remedy at law; the Employee therefore
also agrees that in the event of said breach or any threat of breach, the
Company shall be entitled to an immediate injunction and restraining order to
prevent such breach and/or threatened breach and/or continued breach by the
Employee and/or any and all persons and/or entities acting for and/or with the
Employee, without having to prove damages, and to all costs and expenses,
including reasonable attorneys' fees and costs, in addition to any other
remedies to which the Company may be entitled at law or in equity.  The terms of
this paragraph shall not prevent the Company from pursuing any other available
remedies for any breach or threatened breach hereof, including but not limited
to the recovery of damages from the Employee.

     (e) SURVIVAL.  The provisions of this Section 7 shall survive any
termination of this Agreement and the Employment Term, and the existence of any
claim or cause of action by the Employee against the Company, whether predicated
on this Agreement or otherwise, shall not constitute a defense to the
enforcement by the Company of the covenants and agreements of this Section 7.
