FORWARD-LOOKING STATEMENTS
 
     In addition to the historical information contained throughout this Annual
Report on Form 10-K, there are forward-looking statements that reflect
management's expectations for the future. A variety of important factors could
cause results to differ materially from such statements. These factors are noted
throughout this Annual Report on Form 10-K and include: the actions of both
current and potential new competitors, rapid changes in technology, financial
market volatility, evolving industry regulation, cash flows into or redemptions
from equity funds, effects of inflation, customer trading patterns, and new
products and services.

                                     PART I
 
ITEM 1.  BUSINESS
 
     Investment Technology Group, Inc., through its wholly-owned broker dealer
subsidiary ITG Inc. (ITG), provides automated equity trading services and
transaction research to institutional investors and brokers. A full service
execution firm, ITG utilizes transaction processing technology to increase the
effectiveness and lower the cost of institutional and other trading. With an
emphasis on ongoing research, ITG offers the following services:
 
     -  ITG POSIT. An electronic stock crossing system
 
     -  ITG QuantEX. A decision-support and execution system
 
     -  Electronic Trading Desk Services. Offers customers trading capabilities
       through the ITG trading desk which utilizes multiple sources of liquidity
 
     -  ITG Platform. A PC based execution system
 
     -  ITG ISIS. A set of analytical tools for systematically lowering
       transaction costs
 
     The Company generates substantially all of its revenue from its POSIT,
QuantEX, and Electronic Trading Desk Services.
 
POSIT(R)(1)
 
     POSIT was introduced in 1987 as a technology-based solution to the trade
execution needs of quantitative and passive investment managers. POSIT is an
electronic stock crossing system through which customers enter buy and sell
orders to trade single stocks and portfolios of equity securities confidentially
among themselves. Orders may be placed on the system either through direct
computer links to the Company's central computer or indirectly by communicating
with the Company's trading desk, which then enters the orders in the central
computer. ITG also entered into strategic alliances, which enable users of other
popular trading systems, to route orders directly to POSIT. Links with ESI
Securities, Bridge Information Systems and BRASS were established in 1994. The
system, which currently accepts orders for approximately 10,000 different equity
securities, may be modified, as the need arises, to include additional equity
securities registered pursuant to Section 12 of the Securities Exchange Act of
1934. Using an algorithm, which establishes the maximum possible matching of buy
and sell orders at scheduled times, the system matches or "crosses" these
orders. Unless otherwise specified by customers, POSIT will match orders
(including multiple orders) which do not contain equal numbers of shares,
resulting in partial order execution. POSIT has been designed to allow customers
trade execution flexibility. Customers may specify constraints on the portion of
a portfolio that trades, such as a requirement that the execution of a buy order
be conditioned upon the concurrent execution of a sell order. Trades are priced
at the midpoint of the best bid and offer on the primary market for each
security at the time of the cross. Price information is provided directly to the
system from a third-party data vendor. There are five scheduled crosses every
business day at approximately 10:00 a.m., 11:30 a.m., 12:30 p.m., 1:30 p.m., and
3:00 p.m. Each scheduled cross is executed within a seven minute window selected
randomly by the system.
 
     Significant attributes of POSIT:
 
     -  POSIT's midpoint pricing saves each party an amount equivalent to half
       the bid/offer spread.
 
     -  POSIT's confidentiality virtually eliminates market impact. In contrast,
       participants in traditional or other open markets constantly face the
       risk that disclosure of an order will unfavorably affect price
       conditions.

     -  Clients pay a low transaction fee on completed transactions, relative to
       the industry average of 5 to 6 cents per share. The Company's revenue
       from the operation of POSIT is derived from transaction fees charged on
       each share crossed through the system.
 
     -  Immediately after each cross, customers are electronically provided with
       comprehensive reports of matched and unmatched (residual) orders.
       Customers can then execute residual orders by traditional means or take
       advantage of the Company's Electronic Trading Desk services (described
       below).
 
     -  Electronic application on client instructions for allocating trades to
       specific customer accounts utilizes average prices and average
       commissions.
 
     Average daily share volume on POSIT has grown from approximately 288,000
shares in 1988 to approximately 13.1 million shares in 1996. In addition to its
traditional customer base of quantitative and passive investors, POSIT has begun
to serve fundamental institutional investors, broker-dealers and international
institutional investors. The POSIT system is currently used by approximately 450
customers, including corporate and government pension plans, insurance
companies, bank trust departments, investment advisors and mutual funds.
 
QUANTEX(R)(2)
 
     ITG QuantEX is the Company's portfolio management trading system, an
advanced tool for technologically sophisticated clients conducting a
medium-to-large volume of trading. QuantEX is what is known on Wall Street as an
"Expert System". QuantEX equips clients to manage every step in the trading
process more efficiently, from decision-making to execution to tracking of trade
list status. From a Sun workstation at their desks, users can access
fully-integrated market information and analytics, execute electronic order
routing and perform trade management functions. To date, trading systems have
generally addressed just one or two of these functions -- a situation which has
left many users with the inefficiency of multiple unrelated systems.
 
     QuantEX is a customized, rule-based expert system that allows traders to
quantify their thought processes. It is designed to embody each clients' trading
style and strategies, and apply them to data on hundreds of stocks, portfolios
or industry groups at once. With QuantEX, clients can flag precisely the same
kinds of moment-to-moment opportunities they would ordinarily want to
pursue -- but do it much more efficiently and rapidly.
 
     QuantEX 3.0, introduced in 1995, is an upgrade of the Company's software,
which provides, among other new features, the following:
 
     -  access to sophisticated ISIS pre- and post-trade analytical tools,
 
     -  "instant" analytics built on widely-used measures,
 
     -  a direct line to the ITG Data Center. The ITG Data Center is an expanded
       historical database that provides closing volume and canned analytics
       based on the raw historical data.
 
     QuantEX analyzes portfolios of securities based on the individual user's
trading strategy. The Company's support specialists translate the trading
criteria developed by the user into a set of proprietary rules for the trading
of securities, which are then encoded into QuantEX. QuantEX applies the
customer's proprietary trading rules to a continuous flow of current market
information on the list of securities selected by the user to generate real-time
decision support. A user's rules can be based on a wide range of quantitative
models or strategies, such as liquidity measures, technical indicators, price
benchmarks, tracking to specific industries and sectors, pairs or other long or
short strategies, index arbitrage, risk measurements and liquidity parameters
for trade urgency, size or timing. QuantEX has sorting capabilities which
highlight the most important trade

decisions according to the user's rules. Charting features provide analysis of
the results of the application of the user's trading strategy.
 
     Trades which are routed through QuantEX to POSIT are charged transaction
fees through POSIT and are not charged separate QuantEX transaction fees. The
Company derives revenue from QuantEX by collecting a transaction fee on each
share which is routed for trading through QuantEX to destinations other than
POSIT but does not derive revenue from either the sale or licensing of the
QuantEX software.
 
     QuantEX also automates the complex trade management requirements typical of
investment strategies that trade large volumes of securities through multiple
sources of liquidity. Orders can be electronically routed to multiple
markets -- not just the New York, American, and regional Stock Exchanges, but
also POSIT, ITG Trading Desk, OTC market-makers, the AZX, and selected
broker/dealers. Trades routed through QuantEX are automatically tracked and
summarized. Each order can be monitored by source of execution, by trade list,
by portfolio or globally with all other orders placed. Trading decisions are
enhanced by applying any combination of criteria to real-time and historical
data on a user-selected universe of stocks and alerting clients to opportunities
that fit their strategies. QuantEX's built-in trade allocation features allow
for automated back-office clearance and settlement.
 
     The Company's product specialists install the system, train users and
provide ongoing support for use of QuantEX's trade execution and analysis
capabilities. Specialists are knowledgeable about portfolio management and
trading as well as the system's hardware and software. The Company's support
team works closely with each customer to develop trading strategies and rules,
explore new approaches and implement system upgrades and enhancements.
 
ELECTRONIC TRADING DESK
 
     To supplement the automated trade execution and analysis services offered
by POSIT and QuantEX, the Company also offers customers trading capabilities
through the Company's trading desk, which is staffed by 22 traders. QuantEX
clients can electronically deliver lists of orders to the ITG Trading Desk. As
orders are executed by ITG, reports are automatically delivered to the client's
terminal. Trading desk personnel are, thereby, able to assist customers with
decision support analyses, generated by QuantEX, and with the execution of
trades. The Trading Desk is a full-service agency execution group that
specialize in the Company's proprietary products. Clients give traders orders to
work throughout the day as well as finish residual orders after POSIT matches.
 
     If a customer fails to submit a portfolio in time for a scheduled POSIT
cross, at the customer's request, the Company will communicate with and seek
interest from other potentially interested customers and conduct an unscheduled
cross. Unmatched or residual orders may be filled by (i) keeping orders in POSIT
for future crosses which will offer different liquidity profiles, (ii) routing
trades electronically through QuantEX to multiple markets, including primary
exchanges, regional exchanges and OTC market-makers or (iii) using the Company's
trading desk to complete trades on an agency basis. The Company has also
developed pricing mechanisms that allow customers to enter orders to cross
shares before the market opens subject to prices determined by specified
formulas, such as weighted average prices throughout the trading day, or the
day's closing prices.
 
ITG PLATFORM
 
     ITG Platform, introduced in the first quarter of 1996, is designed to
provide seamless connectivity to a variety of execution destinations, such as
POSIT, ITG's Electronic Trading Desk and SuperDOT. The Platform is designed to
run on any 486 or Pentium PC in almost any Windows environment, which allows
access to a wide range of execution capabilities, without requiring a dedicated
terminal. It accesses ITG through a standard modem.
 
Investment Technology Group, Inc.
 
                                        5
<PAGE>   6
 
     To execute an order, a ticker symbol (or multiple tickers) is typed in with
buy/sell side and size. A list can be loaded in by using a diskette, or from a
network. Once orders have been loaded, execution instructions can be inputted.
The execution sources range from POSIT, ITG Electronic Trading Desk, SuperDOT,
to OTC market makers. The Platform also allows automatic rerouting of any
residual POSIT trades. For instance, a trader may designate that any listed
residual orders under a certain size be rerouted to the New York Stock Exchange
via SuperDOT. The trader may also choose to reroute the orders back to POSIT for
the rest of the day's matches, or to ITG's Electronic Trading Desk. As the
orders are executed, reports are automatically delivered back to the Platform
giving the users constant feedback on their orders. The orders are displayed in
realtime and the Platform also provides a running average price for each order.
Order status is color-coded to indicate whether the order has been filled,
partially executed, or is awaiting action.
 
     Platform users can access historical data through a direct link with the
ITG Data Center, including a wide array of analytics such as average historical
share volumes, dollar volumes, volatility, and historical spread statistics. The
Platform also allows custom tailored execution reports to fit each user's
requirements.
 
     As of December 31, 1996, there were 36 Platform client sites, with 53
software installations.
 
ISIS RESEARCH
 
     Accessed through ITG QuantEX, ISIS encompasses an equity transaction
database, pre-and post-trade analytics, a proprietary transaction-cost model, a
framework for development of trading strategies and a set of model strategies.
Together, these tools assist clients in making the most cost-effective trading
decisions by measuring the cost impacts of alternative courses of action. With
ISIS, clients can also:
 
     -  Increase the cost-effectiveness of trading strategies,
 
     -  Construct portfolios to minimize the cost of execution,
 
     -  Minimize transaction costs of trading lists by targeting positions that
       are especially illiquid, difficult, or costly to trade,
 
     -  Focus resources on the most consequential transactions,
 
     -  Estimate the cost of trading on a principal versus agency basis, and
 
     -  Measure the cost-effectiveness of completed trades against any
       benchmark.
 
     With the release of QuantEX 3.0 in 1995, users can define, store and run
custom pre- and post-trade reports, selecting from a wide variety of analytics.
Analytics can also be viewed directly on the execution page and incorporated
into trading strategies. Among the available analytics are measures of momentum,
price volatility and liquidity, including an explicit estimate of market impact.
 
GLOBAL POSIT
 
     The Company is pursuing the international market in a variety of ways,
joint-venturing with strategic partners and developing specially-tailored
versions of ITG services. The Company has also developed a global version of
POSIT, which provides U.S. and global clients with electronic trade-matching
capabilities for international equities. Besides housing the operation of Global
POSIT, the Company's new Boston office offers services to foreign investors
trading in the U.S. and worldwide clientele trading non-U.S. securities. Total
Global POSIT revenues for 1996 amounted to approximately $513,000.

AUSTRALIAN POSIT
 
     The Company has licensed POSIT to Burdett, Buckeridge & Young, one of
Australia's leading brokerage firms, for development and marketing of an
Australian POSIT cross, which began operating in the first quarter of 1995.
Through this relationship the Company is also pursuing U.S. business from
Australian investors and providing U.S. clients with access to the Australian
marketplace. Total Australian POSIT revenues for 1996 amounted to approximately
$279,000.
 
CANADIAN QUANTEX
 
     The Company was party to a license agreement with RBC Dominion Securities
("RBC"), under which the Company was entitled to receive royalties for licensing
the rights to the Company's QuantEX product to RBC beginning in 1991. RBC used
the QuantEX license to develop a version of QuantEX for the Canadian markets. In
conjunction with the spin-off of VERSUS Technologies, Inc. ("VERSUS") from RBC
in 1995, the Company exchanged its licensing agreement asset with RBC for a 9%
equity interest in VERSUS. VERSUS is a Canadian technologyfocused trade
automation firm based in Toronto. Currently, Canadian QuantEX is the only direct
electronic access to the Canadian exchanges for U.S. and Canadian institutions.
The Company is also providing Canadian investors with access to POSIT and other
ITG services.
 
AZX
 
     AZX Inc., the operators of the Arizona Stock Exchange3 ("AZX") and the
Company announced in February 1995 the formation of a new alliance between the
two organizations. The Company's wholly-owned broker-dealer subsidiary, ITG, has
been named as the executing broker for all transactions executed on AZX. AZX is
the only open screen call market for equity trading, which conducts two daily
auctions at 5:00 PM and 5:30 PM Eastern time. The auctions are designed to allow
institutional investors and broker/dealer participants to trade anonymously and
at true market prices with low transaction costs. In February 1995, ITG, at
customers' request, began placing the unmatched portion of client portfolios
from POSIT into AZX's daily auction. Since ITG is the executing broker for all
AZX trades, ITG clients have the option of obtaining one combined average price
for orders crossed on both systems (i.e., the POSIT cross is combined with the
previous night's AZX auction). The Company performs this function as a courtesy
to its clients. The Company charges its direct incremental costs to AZX. Total
net revenues for 1996 amounted to approximately $412,000.
 
REGULATION
 
     The Company is subject to extensive Federal and state regulation by various
regulatory organizations which are charged with protecting the interests of the
investing public and the integrity of the securities markets. In addition, the
National Association of Securities Dealers, Inc. (the "NASD") requires strict
compliance with its rules and regulations. Failure to comply with any applicable
laws, rules or regulations could result in fines or penalties, suspensions or
revocations of licenses or expulsion from membership, any one of which could
have a material adverse effect on the Company.
 
NO ACTION LETTER
 
     In connection with the development of POSIT, Jefferies and Company, Inc.
("Jefferies & Co.") obtained a no action letter in which the staff of the
Securities and Exchange Commission (the "Commission") indicated that it would
take no action with respect to the fact that POSIT would be operated without
registration as an exchange. As a result, POSIT has not been registered with the
Commission as an exchange,
 
- ---------------
 
(3)The Arizona Stock Exchange, (the "Exchange") operated by AZX, Inc., is not
registered with the US Securities and Exchange Commission ("SEC", or the
"Commission") nor is it a self-regulatory organization. Due to the low volume of
trading on the Exchange, the SEC granted it an exemption from exchange
registration. The Exchange is subject to limited oversight by the SEC.
 
Investment Technology Group, Inc.
 
                                        7

although ITG is registered as a broker-dealer and is subject to regulation as
such. Material changes to POSIT will require prior notice to the Commission. One
of the stated purposes of Rule 17a-23 is to provide the Commission with
information necessary to monitor and evaluate automated trade execution systems.
There can be no assurance that the Commission will not in the future seek to
impose more stringent regulatory requirements on the operation of automated
trade execution systems such as POSIT. In addition, certain of the securities
exchanges have actively sought to have more stringent regulatory requirements
imposed upon automated trade execution systems. There can be no assurance that
Congress will not enact legislation applicable to automated trade execution
systems.
 
LICENSE AND RELATIONSHIP WITH BARRA
 
     In 1987, Jefferies & Co. and BARRA Inc. ("BARRA") formed a joint venture
for the purpose of developing and marketing POSIT. In 1993, Jefferies & Co.
assigned all of its rights relating to the joint venture and the license
agreement to ITG.
 
     The technology used to operate POSIT is licensed to the Company pursuant to
a perpetual license agreement between the Company and the joint venture. The
license agreement grants ITG the exclusive right to use certain proprietary
software necessary to the continued operation of POSIT and a non-exclusive
license to use proprietary software that operates in conjunction with POSIT. The
Company pays quarterly royalties to the joint venture to use other proprietary
software that operates in conjunction with POSIT equal to specified percentages
of the transaction fees charged by the Company on each share crossed through
POSIT. For the years ended December 31, 1996, 1995 and 1994, BARRa received
aggregate royalty payments from the joint venture of $8.8 million, $6.0 million,
and $5.0 million, respectively, under the license agreement. Under the terms of
the joint venture, the Company and BARRa are prohibited from competing directly
or indirectly with POSIT.
 
     The license agreement permits BARRA on behalf of the joint venture to
terminate the agreement upon certain events of bankruptcy or insolvency or upon
an uncured breach by the Company of certain covenants, the performance of which
are all within the control of the Company. Although the Company does not believe
that it will experience difficulty in complying with its obligations under the
license agreement, any termination of the license agreement resulting from an
uncured default would have a material adverse effect on the Company's results of
operations.
 
     Under the license agreement and the terms of the joint venture, BARRA
continues to provide certain support services to the Company in connection with
the operation of POSIT, including computer time, software updates and the
availability of experienced personnel. BARRA also provides support for the
development and maintenance of POSIT.
 
     Under the terms of the joint venture, BARRA generally has the right to
approve any sale, transfer, assignment or encumbrance of the Company's interest
in the joint venture. The POSIT joint venture may earn a royalty from licensing
the POSIT technology to other businesses. The joint venture licensed to ITG and
BBY the right to use the POSIT technology for crossing equity securities in
Australia.
 
     In the first quarter of 1997, BARRA announced a joint venture with Prebon
Yamane to market POSIT-FRA, the first computer-based system for crossing forward
rate agreements (FRAs). The Company cannot estimate what the effect will be on
future earnings or profitability as the Joint Venture has not approved
definitive documentation for POSIT-FRA.
 
     In May 1990, ITG Global Trading, Inc. ("Global Trading") and BARRA
International, Ltd., an affiliate of BARRA, formed a joint venture for the
purposes of developing Global POSIT. The joint venture granted to Global Trading
the exclusive rights to use Global POSIT. In connection with the May 1994
initial public offering (the "Offering"), Jefferies Group, Inc. ("Jefferies
Group") contributed Global Trading and its respective rights in Global POSIT to
the Company. Any net earnings will be divided equally between the

Company and BARRA International, Ltd. Under the terms of the joint venture, the
Company and BARRA International, Ltd. are prohibited from competing directly or
indirectly with Global POSIT.
 
COMPETITION
 
     The automated trade execution and analysis services offered by the Company
compete with services offered by leading brokerage firms and other information
services and transaction processing firms. Many of the Company's competitors
have substantially greater financial, research and development and other
resources than the Company. The Company believes that its services compete on
the basis of cost, timeliness of execution and probability of trade completion.
The probability of trade execution through POSIT depends on a number of factors,
including, primarily, the security for which an order is placed on the system.
In general, orders placed on the system for securities which trade in high
volumes tend to have high rates of trade execution through POSIT, while orders
for securities which trade in low volumes have low rates of trade execution
through POSIT. Although the Company believes that POSIT, QuantEX, and the
Electronic Trading Desk services have established certain competitive
advantages, the Company's ability to maintain these advantages will require
continued investment in the development of the Company's services, additional
marketing activities and customer support services. There can be no assurance
that the Company will have sufficient resources to continue to make this
investment, that the Company's competitors will not devote significantly more
resources to competing services or that the Company will otherwise be successful
in maintaining its current competitive advantages.
 
     The Company also competes with various national and regional securities
exchanges for trade execution services. Some of these exchanges have made
efforts to regain transaction volume lost to POSIT and other automated trade
execution services. The New York Stock Exchange now offers members the
opportunity to participate in two daily after-hours stock crosses. The Arizona
Stock Exchange also operates two after-hours auctions (see discussion above
under AZX). The Company believes that POSIT customers who participate in
afterhours stock crossing systems do so primarily to seek completion of trades
which have not been executed during trading hours. There can be no assurance
that these or other exchanges will not take further steps to regain transaction
volume from POSIT or to limit its future growth.
 
RESEARCH AND PRODUCT DEVELOPMENT
 
     The Company believes that fundamental changes in the securities industry
have increased the demand for technology-based services. The Company devotes a
significant portion of its resources to the development and improvement of these
services. Important aspects of the Company's research and development effort
include enhancements of existing software, the ongoing development of new
software and services and investment in technology to enhance the Company's
efficiency. The software programs, which are incorporated into the Company's
services, are subject, in most cases, to copyright protection. Research and
development costs were $6.0 million, $4.9 million and $3.2 million for 1996,
1995 and 1994, respectively.
 
     In connection with such research and product development and capital
expenditures to improve other aspects of its business, the Company incurs
substantial expenses that do not vary directly, at least in the short term, with
fluctuations in securities transaction volumes and revenues. In the event of a
material reduction in revenues, the Company may not reduce such expenses quickly
and, as a result, the Company could experience reduced profitability or losses.
Conversely, sudden surges in transaction volumes can result in increased profit
and profit margin. To ensure that it has the capacity to process projected
increases in transaction volumes, the Company has historically made substantial
capital and operating expenditures in advance of such projected increases,
including during periods of low transaction volumes. In the event that such
growth in transaction volumes does not occur, the expenses related to such
investments could, as they have in the past, cause reduced profitability or
losses. Additionally, during recent periods of high transaction volumes and
increased revenues, the Company has also made substantial capital and operating
expenditures to enhance future growth prospects.

     The Company currently employs 68 personnel in software development,
management and implementation. The Company also works closely with BARRA on the
development of POSIT enhancements. The Company expects to continue this level of
investment to develop improved services and continue the development of new
services.
 
NUMBER OF PERSONS EMPLOYED
 
     As of December 31, 1996, the Company employed 157 personnel.
 
ITEM 2.  PROPERTIES
 
     The Company's principal offices are located at 900 Third Avenue in New York
City where the Company occupies approximately 16,000 square feet of office space
under a sublease with Jefferies Group that expires in December 2004. The Company
believes that the terms of such sublease are no less favorable to the Company
than could have been obtained from an unaffiliated party. In February 1996, the
Company leased approximately 2,500 square feet of additional office space in the
900 Third Avenue location to supplement the existing office space. The
additional space is leased for eighteen months. In May of 1997, the Company
plans to move its principal offices to 380 Madison Avenue in New York City. The
spaces in 900 Third Avenue will be subleased to a third party. The Company also
maintains a search, development and technical support services facility in
Culver City, California. The California facility is leased by the Company
pursuant to a lease agreement which expires in December 2005. In April 1995, the
Company completed the build-out and occupancy of a 10,500 square feet office in
Boston, Massachusetts. The site is a "hot" backup facility for the Company's
operations. The site is currently used as a regional office for Financial
Engineering Research, QuantEX support and the Global POSIT operations.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     The Company is not party to any legal proceedings.
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

</TABLE>
 
     The increase in total assets is primarily due to an increase in cash and
cash equivalents. Current assets made up approximately 76.3% of total assets.
Securities owned are valued at market. Securities owned consisted of municipal
securities as of December 31, 1996, and are part of cash management activities
of the Company, along with Investment in Limited Partnership. These municipal
securities generally mature within one to one and a half years.
 
     The increase in total liabilities is mostly due to an increase in accounts
payable and accrued expenses, which consisted primarily of soft dollar
liabilities of $2.1 million and bonus accruals of $2.5 million. Software
royalties payable, which is the accrual for the fourth quarter POSIT royalties,
increased $480,000. This was a result of higher POSIT volume in the fourth
quarter of 1996.

     Increased revenues is due to a growing use of POSIT, QuantEX and the
Company's other electronic trading desk services. For the year ended December
31, 1996, POSIT revenues were approximately 49% or $22.1 million above the
comparable period for 1995, while QuantEX revenues were approximately 57% or
$9.0 million above the comparable period for 1995. For the year ended December
31, 1996, other electronic trading desk services were 83% or $8.1 million above
the comparable period for 1995.
 
     The Company currently reports revenues net of soft dollars collected. The
Company previously reported soft dollars on a "gross" basis. Soft dollars
collected were reported as revenues and, in an equal and offsetting amount, as
soft dollar expense. The historical financial statements have been reclassified
to reflect revenue net of soft dollars collected. Soft dollars are those
incremental amounts of commission dollars collected in addition to the Company's
charge for executions. These incremental amounts are used to satisfy customers'
third-party research services.

</TABLE>
 
     The increase is primarily due to the expense associated with a higher
volume of transactions in 1996. In addition, QuantEX is a larger portion of
total volume, causing higher execution charges. The Company received a $621,000
adjustment in the fourth quarter of 1996 against charges incurred in the first
three quarters of 1996 for exchange-related execution fees.

scheduled to occur in the second quarter of 1997.

impacted by a lower tax rate resulting from the recognition of research and
development tax credits attributable to prior periods.

DEPENDENCE ON MAJOR CUSTOMERS
 
     During 1996, revenue received by the Company from its 10 largest customers
accounted for approximately 39.6% of the Company's total revenue while revenue
received from the three largest customers accounted for 9.3%, 6.8% and 5.6% of
total revenue. During 1995, revenue received by the Company from its 10 largest
customers accounted for approximately 43.6% of the company's total revenue while
revenue received from the three largest customers accounted for 8.3%, 7.3%, and
7.1% of total revenue. Customers may discontinue use of the Company's services
at any time. During 1994, revenue received by the Company from its 10 largest
customers accounted for approximately 45.4% of the company's total revenue while
revenue received from the three largest customers accounted for 7.6%, 6.7%, and
6.3% of total revenue. The loss of any significant customers could have a
material adverse effect on the Company's results of operations. In addition, the
loss of significant POSIT customers could result in lower share volumes of
securities offered through POSIT which may adversely affect the liquidity of the
system.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has historically financed its business through cash flow from
operations, equity investments made by Jefferies Group and, to a lesser extent,
through operating lease agreements with Jefferies Group for premises and
equipment. Since November 1994, the Company has purchased its own equipment. The
Company's liquidity and capital resource requirements are the result of the
funding of working capital needs, primarily consisting of compensation, benefits
and transaction processing fees and software royalty fees. Historically, all
working capital requirements have been met by cash from operations and
subordinated loans and equity investments made by Jefferies Group.
 
     Immediately prior to the Offering, the Company and Jefferies Group entered
into an Intercompany Borrowing Agreement which provides for aggregate borrowings
under the facility of up to $15.0 million. Amounts borrowed under the facility
are not restricted as to their use by the Company. The facility bears interest
at a floating rate equal to 1.75% above the average one month London Interbank
Offered Rate. Jefferies Group is not committed to advance funds, and the Company
is not obligated to borrow funds, under the facility. The Company may borrow
funds from other parties. The facility may be terminated by Jefferies Group in
the event of an uncured default by the Company.
 
     The Company's principal financial commitments consist of obligations under
lease and sublease agreements with third parties, Jefferies Group and Jefferies
& Co., and for certain offices and equipment.
 
     The Company believes that its cash flow from operations and its existing
cash balances will be sufficient to meet its cash requirements. The Company
generally invests its excess cash in money market funds, municipal securities
and other short-term investments. At December 31, 1996 and 1995, such cash
equivalents amounted to $43.7 million and $17.8 million, respectively. Cash
equivalents are part of the cash management activities of the Company and
generally mature within 90 days. Additionally, the trade receivable from
affiliate of $2.8 million is due within 30 days.
 
EFFECTS OF INFLATION
 
     The Company does not believe that the relatively moderate levels of
inflation which have been experienced in North America in recent years have had
a significant effect on its revenue or its profitability. However, high
inflation may lead to higher interest rates which might cause money to move from
equity funds to bond funds or money market funds.

       MANAGEMENT'S RESPONSIBILITY FOR COMPLIANCE AND FINANCIAL REPORTING
 
TO THE SHAREHOLDERS:
 
     The management of Investment Technology Group, Inc. (the "Company") is
responsible for the integrity and objectivity of the financial information
presented in this Annual Report. Financial information appearing throughout the
Annual Report is consistent with that in the accompanying financial statements.
The financial statements have been prepared by management of the Company in
conformity with generally accepted accounting principles in the United States
and comply, in all material respects, with guidelines of the International
Accounting Standards Committee. The financial statements reflect, where
applicable, management's best judgments and estimates.
 
     The management of the Company has established and maintains an internal
control structure and monitors that structure for compliance with established
policies and procedures. The objectives of an internal control structure are to
provide reasonable, but not absolute, assurance as to the integrity and
reliability of the financial statements, the protection of assets from
unauthorized use or disposition, and that transactions are executed in
accordance with management's authorization.
 
     Management also recognizes its responsibility to foster and maintain a
strong ethical environment within the Company to ensure that its business
affairs are conducted with integrity and in accordance with high standards of
personal and corporate conduct. This responsibility is characterized and
reflected in the Company's Statement of Policy on Standards of Employee Conduct,
which is distributed to all employees of the Company. As part of the monitoring
system, the Company maintains Corporate Compliance Personnel, who have oversight
responsibilities for administering and coordinating the application of these
standards of conduct. Senior legal and compliance personnel have been directed
to report compliance concerns directly to the President of the Company. Ongoing
oversight of compliance activities is the responsibility of the Company's
President.
 
     The Company's Board of Directors appoints an Audit Committee composed
solely of outside directors. The function of the Audit Committee is to oversee
the accounting, reporting, audit and internal control policies and procedures
established by the Company's management. The Committee meets regularly with
management and the internal and independent auditors. The auditors have free
access to the Audit Committee without the presence of management. The Committee
reports regularly to the Board of Directors on its activities, and such other
matters as it deems necessary. Ernst & Young LLP, independent auditors, performs
an internal audit program for the Company and reports directly to the Audit
Committee on matters of internal control.
 
     The Company's annual consolidated financial statements have been audited by
KPMG Peat Marwick LLP, independent auditors, who were appointed by the Board of
Directors. Management has made available to KPMG Peat Marwick LLP all of the
Company's financial records and related data, as well as the minutes of
directors' meetings.
 
     Furthermore, management believes that all its representations to KPMG Peat
Marwick LLP are valid and appropriate. In addition, KPMG Peat Marwick LLP, in
determining the nature and extent of their auditing procedures, considered the
Company's accounting procedures and policies and the effectiveness of the
related internal control structure.
 
     Management believes that, as of December 31, 1996, the Company's internal
control structure was adequate to accomplish the objectives discussed herein.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Investment Technology Group, Inc.:
 
     We have audited the accompanying consolidated statement of financial
condition of Investment Technology Group, Inc. and subsidiaries as of December
31, 1996 and 1995 and the related consolidated statements of operations, changes
in stockholders' equity and cash flows for each of the years in the three-year
period ended December 31, 1996. 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 in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Investment
Technology Group, Inc. and subsidiaries as of December 31, 1996 and 1995 and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1996 in conformity with generally accepted
accounting principles in the United States and International Accounting
Standards.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
     The Consolidated Financial Statements include the accounts of Investment
Technology Group, Inc. and its wholly-owned subsidiaries (collectively, the
"Company" or "ITGI"), principally ITG Inc. ("ITG"), a Delaware corporation, and
a registered broker-dealer in securities under the Securities Exchange Act of
1934, and ITG Global Trading, Inc. ("Global Trading") which is a 50% partner in
the Global POSIT joint venture. Jefferies Group, Inc. ("Jefferies Group") owned
over 80% of the Company's common stock at December 31, 1996.
 
     In March 1994, ITGI was formed for the purpose of holding 100% of the stock
of ITG, which was a wholly-owned subsidiary of Jefferies Group. After its
formation, ITGI had a capital structure of preferred stock (5.0 million shares
authorized, par value $.01 per share, no shares issued or outstanding) and
common stock (30.0 million shares authorized, par value $.01 per share, no
shares issued or outstanding).
 
     Immediately prior to the consummation of an initial public offering (the
"Offering") in May 1994, ITGI issued 15.0 million shares of its common stock in
exchange for all of the issued and outstanding shares of common stock of ITG
(10.0 million shares) held by Jefferies Group. In addition, Jefferies Group
contributed Global Trading to ITGI and its royalty interest in Canadian QuantEX
to ITG. This transaction was accounted for as an exchange of ownership interests
under common control, and therefore, the assets and liabilities of these
entities were not revalued.
 
     In May 1994, the Company consummated the Offering and issued 3.7 million
shares of common stock for $48.1 million ($13 per share), less underwriting
discounts and commissions of $3.4 million and offering expenses of $1.1 million.
Immediately following the Offering, Jefferies Group owned 80.2% of the
outstanding common stock of the Company.
 
COMBINED FINANCIAL STATEMENT PRESENTATION
 
     Prior to May 1994, the accompanying consolidated financial statements,
presented on an historical basis, include the accounts of ITG, Global Trading
and the royalty interest in Canadian QuantEX on a combined basis. ITG was
incorporated in the State of Delaware as a wholly-owned subsidiary of Jefferies
Group in 1991 with operations beginning in March 1992. From 1987 to February
1992, ITG was operated as the investment technology division of Jefferies &
Company, Inc. ("Jefferies & Co."), a wholly-owned subsidiary of Jefferies Group.
These combined statements are presented as if the Company had existed as a
corporation separate from Jefferies Group prior to May 1994 and include the
historical assets, liabilities, revenues and expenses that are directly related
to the Company's operations. The retained earnings (accumulated deficit)
reflected in the accompanying combined financial statements have been recorded
as a result of net earnings (loss) from the combined operations of the Company,
on a historical basis.
 
     The financial information included herein may not necessarily reflect what
the financial position, results of operations or cash flows of the Company would
have been if it were not related to Jefferies Group.
 
     All material intercompany balances and transactions have been eliminated in
consolidation and combination. Certain prior period amounts have been
reclassified to conform to the 1996 financial statement presentation. The
Company previously reported soft dollars on a "gross" basis. Soft dollars
collected were reported as revenues and, as an equal and offsetting amount, soft
dollar expense. The accompanying historical financial statements have been
reclassified to reflect revenue net of soft dollars collected. Soft dollars are
those incremental amounts of commission dollars collected in addition to the
Company's charge for executions. These incremental amounts are used to satisfy
customers' third-party research services.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
BUSINESS SEGMENT
 
     Through its wholly-owned, broker/dealer subsidiary, ITG, the Company, is a
leading provider of technology-based equity trading services and transaction
research to institutional investors and brokers. ITG services help clients to
access liquidity, execute trades more efficiently and make better trading
decisions.
 
GOODWILL
 
     In May 1991, Jefferies Group acquired Integrated Analytics Corporation
("IAC") and contributed its business to ITG in 1992. IAC's principal product,
MarketMind, was used to develop the Company's QuantEX product. Goodwill, which
represents the excess of purchase price for IAC over the fair value of the IAC
net assets acquired, is amortized on a straight-line basis over ten years. The
Company assesses the recoverability of this intangible asset by determining
whether the amortization of the goodwill balance over its remaining life can be
recovered through undiscounted future operating cash flows of the acquired
operation. At December 31, 1996 and 1995, goodwill amounted to $2.5 million and
$3.0 million, net of accumulated amortization of $2.8 million and $2.3 million,
respectively.
 
PREMISES AND EQUIPMENT
 
     Premises and equipment are carried at cost and are depreciated using the
straight-line method over the estimated useful lives of the assets (generally
three to five years). Leasehold improvements are amortized using the
straight-line method over the lesser of the estimated useful lives of the
related assets or the noncancelable lease term.
 
REVENUES
 
     Revenues primarily consist of commission revenues. Trade receivable from
affiliate consists of commissions receivable.
 
     Transactions in securities, commission revenues and related expenses are
recorded on a trade-date basis.
 
EXPENSES
 
     Compensation and employee benefits include base salaries, bonuses,
employment agency fees, part-time employees, commissions paid to Jefferies & Co.
employees (note 8) and fringe benefits, including employer contributions for
medical insurance, life insurance, retirement plans and payroll taxes.
Transaction processing consists of floor brokerage and clearing fees. Software
royalties are payments to BARRA, Inc., the Company's joint venture partner in
POSIT. Royalty payments are calculated at an effective rate of 13% of adjusted
POSIT revenues. The royalty payments related to Global Trading are calculated at
an effective rate of 50%. Occupancy and equipment includes rent, depreciation,
amortization of leasehold improvements, maintenance, utilities, occupancy taxes
and property insurance. Consulting is for equity research and product
development activities which the Company believes it is advantageous to
out-source. Telecommunications and data processing services include costs for
computer hardware, office automation and workstations, data center equipment,
market data services and voice, data, telex and network communications. Other
general and administrative includes goodwill amortization, legal, audit, tax and
promotional expenses. Performance share plans are described in note 7.
 
INCOME TAXES
 
     The Company is a member of the Jefferies affiliated group ("Group") for
purposes of filing a Federal income tax return (i.e., Jefferies Group owns more
than 80% of the Company). The Company's tax liability is determined on a
"separate return" basis. That is, the Company is required to pay to Jefferies
Group its

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
proportionate share of the consolidated tax liability plus any excess of its
"separate" tax liability (assuming a separate tax return were to be filed by the
Company) over its proportionate amount of the consolidated Group tax liability.
Alternatively, Jefferies Group is required to pay the Company an "additional
amount" for the amount by which the consolidated tax liability of the Group is
decreased by reason of inclusion of the Company in the Group.
 
     Consistent with the tax-sharing agreement above, the consolidated financial
statements reflect an allocation of income tax expense (benefit) for the Company
as if it had been a legal entity for the periods prior to May 1994. The
consolidated tax provisions are shown in note 4 to the notes to consolidated
financial statements. On a separate company basis, the consolidated tax
provisions, including the recognition of the deferred tax asset discussed in
note 4, would not be materially different from those presented.
 
     Deferred tax assets and liabilities reflect the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases. Deferred tax
assets and liabilities are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to
reverse. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.
Past effects of such changes in the rates were not material to the combined
financial statements.
 
CAPITALIZED SOFTWARE
 
     The Company capitalizes software development costs where technological
feasibility of the product has been established. The establishment of
technological feasibility and the ongoing assessment of recoverability of
capitalized software development costs requires considerable judgment by
management with respect to certain external factors, including, but not limited
to, technological feasibility, anticipated future gross revenues, estimated
economic life and changes in software and hardware technologies. The Company is
amortizing capitalized software costs using the straight-line method over the
estimated economic useful life, the average life of which is two years.
Amortization begins when the product is available for release to the customers.
 
RESEARCH AND DEVELOPMENT
 
     Research and development costs were $6.0 million, $4.9 million and $3.2
million for 1996, 1995 and 1994, respectively. In 1996, 1995 and 1994, $1.6
million, $2.1 million and $1.3 million, respectively, were capitalized (note 3).
 
CASH AND CASH EQUIVALENTS
 
     The Company generally invests its excess cash in money market funds and
other short-term investments that generally mature within 90 days. At December
31, 1996 and 1995, such cash equivalents amounted to $43.7 million and $17.8
million, respectively.
 
INVESTMENT IN LIMITED PARTNERSHIP
 
     Investment in limited partnership consists of an investment in TQA
Arbitrage Fund L.P. ( the "Fund"), a Delaware limited partnership. The Fund
invests primarily in convertible securities, and seeks capital appreciation from
its convertible securities portfolio through a combination of convertible
securities purchases and short sales of related stocks focusing on the current
income and capital appreciation available from such strategies with
convertibles. The Company may withdraw any or all of its investment from the
Fund upon at least a thirty days notice. Investment in limited partnership is
valued at market, and unrealized gains or losses are reflected in revenues.

FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     Substantially all of the Company's financial instruments are carried at
fair value or amounts approximating fair value.
 
SECURITIES OWNED
 
     Securities owned are valued at market, and unrealized gains or losses are
reflected in revenues. Securities owned consisted of municipal securities as of
December 31, 1996 and 1995.
 
USE OF ESTIMATES
 
     Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets, liabilities, revenues and expenses and the
disclosure of contingent assets, liabilities, revenues and expenses to prepare
these financial statements in conformity with generally accepted accounting
principles. Actual results could differ from those estimates.
 
RECLASSIFICATIONS
 
     Certain reclassifications have been made to the prior years' amounts to
conform to the current year's presentation.
 
IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF
 
     The Company adopted the provisions of SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed Of, on
January 1, 1996. This Statement requires that long-lived assets and certain
identifiable intangibles be reviewed for impairment whenever events or changes
in circumstance indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows expected
to be generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceed the fair value of the assets. Assets to be disposed
of are reported at the lower of the carrying amount or fair value less costs to
sell. Adoption of the Statement did not have a material impact on the Company's
consolidated financial position, results of operations, or liquidity.
 
TRANSFERS AND SERVICING OF FINANCIAL ASSETS AND EXTINGUISHMENTS OF LIABILITIES
 
     In June 1996, the Financial Accounting Standards Board issued SFAS No. 125,
Accounting for Transfers and Servicing of Financial Assets and Extinguishments
of Liabilities. SFAS No. 125 is effective for transfers and servicing of
financial assets and extinguishments of liabilities occurring after December 31,
1996 and is to be applied prospectively. This Statement provides accounting and
reporting standards for transfers and servicing of financial assets and
extinguishments of liabilities based on consistent application of a financial-
components approach that focuses on control. It distinguishes transfers of
financial assets that are sales from transfers that are secured borrowings.
Management of the Company does not expect that adoption of SFAS No. 125 will
have a material impact on the Company's consolidated financial position, results
of operations, or liquidity.
 
DIVIDENDS
 
     Any future payments of dividends will be at the discretion of the Company's
Board of Directors and will depend on the Company's financial condition, results
of operations, capital requirements and other factors deemed relevant. However,
the Company anticipates that, for the foreseeable future, all earnings will be

any dividends to its stockholders. Immediately prior to the Offering, the
Company declared a dividend payable to its sole stockholder, Jefferies Group, in
the amount of $17.0 million. Such dividend liability was paid after the
consummation of the Offering.

</TABLE>
 
     The Company believes that it is more likely than not that the deferred tax
asset will be realized pursuant to the Company's Tax Sharing Agreement with
Jefferies Group which entitles the Company to a compensating tax payment from
Jefferies Group.
 
(5) DEBT
 
     The Company had no term debt as of December 31, 1996 and 1995. Immediately
prior to the Offering, the Company entered into an intercompany borrowing
agreement with Jefferies Group permitting the Company to borrow up to $15.0
million. Any outstanding balance will be due March 31, 1999 and will accrue
interest at 1.75% above the one month London Interbank Offering Rate.
 
(6) EMPLOYEE BENEFIT PLANS
 
     Substantially all employees of the Company are covered by a defined benefit
pension plan sponsored by Jefferies Group. The defined benefit pension plan is
subject to the provisions of the Employee Retirement Income Security Act of
1974. The Jefferies Group funding policy is to contribute to the defined benefit
pension plan at least the minimum amount that can be deducted for Federal Income
Tax purposes. The plan assets consist of approximately 60% equities and 40%
fixed income securities.
 
     The net periodic pension cost allocated to the Company was $151,000,
$101,000 and $137,000 in 1996, 1995 and 1994, respectively.
 
     Jefferies Group incurs expenses related to various benefit plans covering
substantially all employees, including an Employee Stock Purchase Plan and a
profit sharing plan, which includes a salary reduction feature designed to
qualify under Section 401(k) of the Internal Revenue Code. Employee
contributions under the ESPP are voluntary and are made via payroll deduction.
The employee contribution are used to purchase the Jefferies Group common stock
which is then held in an outside trust account. The Company matches employee
contributions at a rate of 15% (more, if profits exceed targets set by the
Company's Board of Directors). The Company's match vests after two years.
 
     Jefferies Group has a Capital Accumulation Plan (CAP) for certain officers
and key employees of Jefferies Group and ITG. Participation in the CAP is
optional, with those who elect to participate agreeing to defer graduated
percentages of their compensation. The plan allows selected employees to acquire
the Jefferies Group common stock at a 15% discount with 50% of the amount
deferred. The remaining 50% of the amount deferred is placed in a Profit-Based
Deferred Compensation Account that earns interest at a rate based on the
performance of the Company. Jefferies Group will from time to time repurchase
shares of its common stock in

the open market for use in this plan. The Company recognizes compensation cost
related to the 15% discount and interest on Profit-Based Deferred Compensation
Accounts.
 
     For 1996, 1995 and 1994, the Company expensed and contributed to these
plans $1,590,000, $567,000, and $534,000, respectively.
 
(7) TERMINATION OF PLANS EXPENSE
 
     In connection with the Offering, certain management employment agreements,
the Performance Share Plans (consisting of a 12.7% phantom equity interest in
ITG and an annual profits bonus component) and non-compensatory ITG stock
options (on 10% of the outstanding shares of ITG common stock) were terminated
as of May 1, 1994 in exchange for $31.1 million in cash, a portion of which was
used to purchase Jefferies Group common stock. The Company, prior to December
31, 1993, had expensed and paid to Jefferies Group an additional $9.4 million
related to the above-mentioned Performance Share Plans. Immediately prior to the
consummation of the Offering, Jefferies Group transferred its $9.4 million
liability and an equivalent amount of cash to the Company to be applied by the
Company as part of the termination of the Performance Share Plans. The total
liability in connection with the above-mentioned plans was $40.5 million. Of the
non-recurring expense of $31.1 million, approximately $900,000 was recorded in
Performance Share Plans expense in the first two quarters of 1994 under the
terms of the prior agreement. The total Performance Share Plans expense recorded
for the first two quarters of 1994 was $1.5 million. The remaining $600,000 of
such expense was for the annual profits bonus component of the Performance Share
Plans for January 1, 1994 through May 1, 1994 (the termination date of the
above-mentioned plans). Only the future annual profits bonus component (post
Offering) of the above-mentioned plans was determined to be a component of the
$40.5 million liability. The annual profits bonus component was earned during
the period January 1, 1994 through May 1, 1994 by the payees regardless of the
Offering. The remaining liability of $30.2 million was recorded as Termination
of plans expense in the second quarter of 1994.
 
(8) RELATED PARTY TRANSACTIONS
 
     In connection with the Offering, the Company entered into certain
agreements (e.g., tax sharing agreement, service agreements, clearing agreement,
development rights agreement, revenue sharing agreement and lease agreements) as
described below:
 
     Jefferies & Co. has provided specified administrative services to the
Company at fixed monthly costs. Services performed outside the scope of the
service agreements have been provided at jointly negotiated costs.
Administrative services include human resources, telecommunications and data
processing, legal, accounting and compliance. The costs of such services to the
Company during 1996, 1995 and 1994 were $690,000, $584,000 and $569,000,
respectively.
 
     Employees of the Company have also been provided with certain employee
benefits, including medical, dental, life and disability insurance under plans
maintained by Jefferies & Co., which have been charged to the Company based on
Jefferies & Co.'s actual costs. In addition, third party expenses including
telecommunication and quotation costs, floor brokerage, legal and accounting
fees, exchange fees and other insurance costs, including fidelity bond coverage
and directors and officers liability coverage, have been provided at cost.
 
     The Company paid to Jefferies & Co. an aggregate of $502,000, $432,000 and
$446,000 for 1996, 1995 and 1994, respectively, as compensation to Jefferies &
Co.'s account executives for introducing customers to POSIT.
 
     In addition, Jefferies & Co. has provided substantially all clearing
services to the Company. Aggregate costs of such services to the Company were
$7.3 million, $4.6 million and $4.4 million during 1996, 1995 and 1994,
respectively, included in transaction processing expenses.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     Occupancy and equipment rental expense has been partially provided to the
Company at cost by Jefferies Group.
 
     W & D Securities, Inc. performs certain execution services at the New York
Stock Exchange and other exchanges for the Company. In order to comply with
regulatory requirements of the NYSE that generally prohibit NYSE members and
their affiliates from executing, as principal and, in certain cases, as agent,
transactions in NYSE-listed securities off the NYSE, Jefferies Group gave up its
formal legal control of W & D, effective January 1, 1983, by exchanging all of
the W & D common stock owned by it for non-voting preferred stock of W & D. In
the event that Jefferies Group were to regain ownership of such common stock,
Jefferies Group believes that the NYSE would assert that W & D would be in
violation of the NYSE's rules unless similar arrangements satisfactory to the
NYSE were made with respect to the ownership of the common stock. While the NYSE
has generally approved the above arrangements, there can be no assurance that it
will not raise objections in the future. The Company believes that it can make
satisfactory alternative arrangements for executing transactions in listed
securities on the NYSE if it were precluded from doing so through W & D. The
cost of these execution services was $6.5 million, $5.4 million and $3.5 million
in 1996, 1995 and 1994, respectively, and is included in transaction processing
expenses. Included in other general and administrative expenses are fees paid to
Jefferies International Limited of $248,000 for various broker and
administrative services, of which $248,000 was reimbursed to the Company by its
affiliate Global Trading.
 
     Jefferies & Co. executes trades in an agency capacity for certain of its
customers. Transaction fees from such trades were $1.7 million, $1.1 million and
$897,000 in 1996, 1995 and 1994, respectively, and are included in the Company's
revenues.
 
     Prior to May 1994, allocations of costs from Jefferies & Co. and Jefferies
Group were done on a proportional cost basis using several methods, including
usage, headcount and square footage. Costs were allocated using the method
deemed most reasonable and appropriate.
 
     During 1994, the Company paid Jefferies & Co. a consulting fee of $56,000
for investment advisory services. The Company also earned interest income and a
commitment fee in connection with a borrowing by Jefferies Group.
 
     The Company believes all the foregoing post-Offering transactions were on
terms substantially no less favorable to the Company than could have been
obtained from unaffiliated parties and that all costs of doing business have
been included. Amounts due from affiliates and amounts due to affiliates are
generally settled on a monthly basis.
 
(9) MARKET RISK AND CONCENTRATIONS OF CREDIT RISK
 
     In the normal course of business, the Company is involved in the execution
of various customer securities transactions. Securities transactions are subject
to the risk of counterparty or customer nonperformance. However, transactions
are collateralized by the underlying security, thereby, reducing the associated
risk to changes in the market value of the security through settlement date.
 
     The settlement of these transactions is not expected to have a material
effect upon the Company's financial statements.
 
(10) NET CAPITAL REQUIREMENT
 
     ITG is subject to the Securities and Exchange Commission Uniform Net
Capital Rule (Rule 15c3-1), which requires the maintenance of minimum net
capital. ITG has elected to use the alternative method permitted by Rule 15c3-1,
which requires that ITG maintain minimum net capital, as defined, equal to
$250,000 or 2% of aggregate debit balances arising from customer transactions,
as defined.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     At December 31, 1996, ITG had net capital of $29.8 million which was $29.6
million in excess of required net capital.
 
(11) ITGI STOCK OPTIONS
 
     At December 31, 1996, the Company had a non-compensatory stock option plan.
Under the 1994 Stock Ownership and Long-term Incentive Plan, non-compensatory
options to purchase 3,650,000 shares of the Company's Common Stock are reserved
for issuance under the plan. Except for certain options granted in conjunction
with the Offering, 20,000 options which vest over two years and 12,377 options
which vest immediately, one third of the options granted vest on the first,
second, and third anniversaries of the date the options were priced. Shares of
Common Stock which are attributable to awards which have expired, terminated or
been canceled or forfeited during any calendar year are generally available for
issuance or use in connection with future awards during such calendar year.
Options that have been granted under the 1994 Stock Ownership and Long-Term
Incentive Plan are exercisable on dates ranging from May 1997 to May 1999. The
Plan will remain in effect until March 31, 2004, unless sooner terminated by the
Board of Directors.
 
     In June 1995, the Board of Directors adopted, subject to stockholder
approval, the Non-Employee Directors' Plan. The Non-Employee Directors' Plan
generally provides for an annual grant to each non-employee director of an
option to purchase 2,500 shares of Common Stock. In addition, the Non-Employee
Directors' Plan provides for the automatic grant to a non-employee director, at
the time he or she is initially elected, of a stock option to purchase 10,000
shares of Common Stock. Stock options granted under the Non-Employee Directors'
Plan are non-qualified stock options having an exercise price equal to the fair
market value of the Common Stock at the date of grant. All stock options become
exercisable beginning at the latter of three months after the date of grant, or
May 4, 1997. Stock options granted under the Non-Employee Directors' Plan expire
five years after the date of grant. A total of 125,000 shares of Common Stock
are reserved and available for issuance under the Non-Employee Directors' Plan.
 
     At the time of the Company's initial public offering in May 1994, stock
options to acquire an aggregate of 2,728,000 shares of Common Stock were granted
to officers and other employees of the Company. Of these options granted,
2,442,000 shares were 100% vested on May 4, 1994. In 1995, the Compensation
Committee of the Board of Directors determined that a repricing of such options
would serve to provide enhanced incentives to officers and employees of the
Company. Accordingly, on the recommendation of the Compensation Committee, the
Company offered a stock option repricing program pursuant to which all holders
(options granted under the Non-Employee Directors' Plan were not eligible for
repricing) of outstanding stock options with an exercise price of $13.00 per
share were permitted to elect to exchange all or a portion of such stock options
for a smaller number of stock options to acquire shares of Common Stock at
exercise price of $13.00, $11.06 and $9.13 per share. The repricing program was
offered to option holders on a value neutral basis using the Black Scholes
option valuation model. In all, approximately 66% of the outstanding stock
options eligible for repricing were repriced at the election of the holders of
such options.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     The Company applies APB Opinion No. 25 and related Interpretations in
accounting for its non-compensatory stock option plans. Accordingly, no
compensation costs have been recognized for its stock option plan. Had
compensation cost for the Company's stock option plans been determined
consistent with FASB Statement No. 123, the Company's net earnings and earnings
per share would have been reduced to the pro forma amounts indicated below:

     The fair value of each option grant is estimated on the date of grant using
the Black Scholes option valuation model with the following weighted average
assumptions used for grants in 1996 and 1995, respectively: zero dividend yield
for all years; risk free interest rates of 6.1 and 6.3 percent; expected
volatility of 49 and 51 percent; and expected lives of four and four years.

</TABLE>
 
     Although the 1994 Plan allows for the granting of performance-based stock
options and restricted stock awards, no such options were granted during 1996
and 1995 and no such options were outstanding at December 31, 1996 and 1995.
 
     In January of 1997, the Company granted to Scott P. Mason a non-qualified
stock option to acquire 1,000,000 shares of Common Stock of the Company, having
an exercise price of $22.175. The option becomes exercisable as to 200,000
shares on May 4, 1997, and thereafter as to an additional 200,000 shares on each
one year anniversary of the date of Scott P. Mason's employment contract
execution. Such options granted were approved by the Compensation Committee of
the Board of Directors in March 1997. The option expires in January 2002.
 
(12) INTEREST
 
     Included in revenues is interest income of $571,000, $46,000 and $616,000
for 1996, 1995 and 1994, respectively.
 
     Included in other general and administrative expenses is interest expense
of $223,000, $53,000 and $10,000 for 1996, 1995 and 1994, respectively.

(15) EARNINGS (LOSS) PER SHARE
 
     Net earnings (loss) per share of common stock is based upon an adjusted
weighted average number of shares of common stock outstanding during 1996, 1995
and 1994. Although the Company actually issued 15.0 million shares to Jefferies
immediately prior to the Offering (See Basis of Presentation in Summary of
Accounting Policies) those shares have been treated in the earnings (loss) per
share calculation as if they had been outstanding during all of 1994. The
average number of outstanding shares for the years ended December 31, 1996, 1995
and 1994 were 18.3 million, 18.5 million and 17.5 million, respectively.
 
(16) UNAUDITED SUPPLEMENTARY FINANCIAL INFORMATION
 
     The following tables set forth certain unaudited financial data for the
Company's quarterly operations in 1996, 1995 and 1994. The following information
has been prepared on the same basis as the annual information presented
elsewhere in this report and, in the opinion of management, includes all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the information for the quarterly periods presented. The
operating results for any quarter are not necessarily indicative of results for
any future period.

     The Company's results of operations are dependent upon trading volumes in
the equity securities markets and variations in transaction volume may cause the
Company's operating results to fluctuate on a quarterly basis. To a lesser
extent, the Company has periodically experienced higher revenue in quarters in
which investment managers seek to adjust their portfolios as a result of changes
in the composition of various broad-based stock market indices.

                                AMENDMENT NO. 2
                            TO EMPLOYMENT AGREEMENT
 
     This Amendment No. 2 to Employment Agreement (the "Amendment") is made and
entered into as of June 30, 1996, by and among Investment Technology Group,
Inc., a Delaware corporation ("Holding"), ITG Inc., a Delaware corporation (the
"Company"), and Dale A. Prouty (the "Employee").
 
     WHEREAS, the Employee wishes to relocate from New York to California and
Holding and Company are willing to allow such relocation subject to the
modifications to the Employee's Employment Agreement as herein provided.
 
     NOW, THEREFORE, the parties hereby agree as follows:
 
     1.  Amendment to Section 2.  Section 2 of the Employment Agreement is
amended by deleting such Section in its entirety and substituting therefor new
Section 2 as follows:
 
          2.  Location of Employment.  The Employee's principal place of
     employment shall be located at the Company's offices in Culver City,
     California. If needed, the Employee agrees to spend approximately one week
     a month (on average) at the Company's offices located in New York, New
     York. No relocation reimbursement shall be made in respect of the
     Employee's relocation to California. The Employee shall not be entitled to
     receive any housing allowance subsequent to June 30, 1996.
 
     2.  Amendment to Section 3.2.  Section 3.2 of the Employment Agreement is
amended by deleting such Section in its entirety and substituting therefor new
Section 3.2 as follows:
 
          3.2.  In addition to the base salary described in Section 3.1, for the
     period commencing July 1, 1996 and ending April 30, 1997, the Employee
     shall be entitled to receive such discretionary bonus as the Chief
     Executive Officer of the Company determines is appropriate, based on the
     Employee's performance during such period. Any payment of a discretionary
     bonus hereunder for the six-month period ending December 31, 1996 or for
     the four-month period ending April 30, 1997 shall be subject to pro-ration
     in the event that the Employee employment hereunder ceases during any such
     period; provided, that no bonus will be payable in any period in which the
     Employee's employment with the Company is terminated unless such
     termination is solely an involuntary termination by the Company without
     cause (as hereinafter defined) or voluntary termination by the Employee for
     Good Reason (as hereinafter defined).
 
     3.  Acknowledgment Concerning "Good Reason".  The employee acknowledges
that any reduction in the Employee's duties or responsibilities made in
connection with the Employee's relocation to California shall not constitute
"Good Reason" as such term is defined in Section 4.4 of the Employment
Agreement.
 
     4.  Amendment to Subsection 4.6.  Subsection 4.6(a) is amended by deleting
such Subsection in its entirety and substituting therefor the following.
 
          (a) The Company shall pay to the Employee (or his heirs or legal
     representatives) the Employee's base salary, at the rate in effect on the
     termination date, net of employment taxes, for the period from the
     termination date through March 31, 1997, periodically in accordance with
     the Company's normal payment procedures, plus (i) if termination occurs
     during 1996, a bonus for the remainder of 1996 or (ii) if termination
     occurs during the period from January 1, 1997 through April 30, 1997, a
     bonus for the remainder of such period, in each case determined by the
     amount of the bonus then in effect, as determined in accordance with
     Section 3.2.
 
     5.  Amendment to Section 7.1.  The last sentence of Section 7.1 is amended
by deleting such sentence and substituting therefor the followings:
 
     In the event that the Employee is terminated by the Company without cause
     or if the Employee resigns for Good Reason, if the Company elects to extend
     the non-competition period, the Company shall pay
 
Investment Technology Group, Inc.

     the Employee during any period that the non-competition period has been

     determined in accordance with Section 3.2.
 
     6.  Effective Date.  This Amendment No. 2 shall become effective on July 1,
1996.

        defined) of 33-1/3% or more of the Voting Stock of ITG, provided that
        such "beneficial ownership" shall not constitute a Change in Control

        combination, the shareholders of such corporation immediately prior to
        the combination beneficially own, directly or indirectly, 50% or less of
        the Voting Stock of the combined company (there being excluded from the
        number of shares beneficially owned by such shareholders, but not from
        the Voting Stock of the combined company, any shares received by any
        such shareholders who are Affiliates of such other company in exchange
        for stock of such other company, provided that in any case that
        Jefferies Group, Inc. is an Affiliate of such other company, such
        exclusion shall not apply to shares received by Jefferies Group, Inc. in
        exchange for stock of such other company). Notwithstanding the
        foregoing, such a combination involving ITGI or ITG shall not constitute

        is the "beneficial owner" of a greater percentage of the Voting Stock of
        ITGI or ITG, as the case may be, than the percentage then held by ITGI

     2.  Employment.  Subject to the terms and conditions contained herein, ITGI

Officer, and the Executive agrees to accept such employment, for the Term of
Employment. During the Term of Employment, the Executive shall exercise all
responsibilities customarily associated with the position of President and Chief
Executive Officer of a company of the size and nature of the Company and shall
perform such duties relating to the management and operation of the Company,
consistent with his position as President and Chief Executive Officer, as may
from time to time be assigned to him by the Board. The Executive shall report
directly to the Board. It is the intent of the Parties that the Executive shall
serve as a member of the Board, and as President and Chief Executive Officer of
ITG, throughout the Term of Employment. During the Term of Employment, the
Executive shall devote substantially all his business time, energy and attention
to the service of the Company and the promotion of its interests; provided,
however, that the Executive may also (i) serve on the boards of directors or
trustees of business enterprises to which the Board gives its written consent,
which shall not be unreasonably withheld, (ii) serve on the boards of directors
or trustees of trade associations and/or charitable organizations or engage in
charitable activities and community affairs, and (iii) manage his personal
investments and affairs, provided that such activities do not materially
interfere with the proper performance of his duties and responsibilities under
this Agreement.
 
     3.  Term of Employment.  The Term of Employment shall begin on January 6,
1997, and shall extend until December 31, 2001: provided, however, that the Term
of Employment shall thereafter be automatically and indefinitely extended for
additional one year periods unless either Party shall give the other six months
prior written notice that he/it is electing not to so extend the Term of
Employment. Following such notice, the Term of Employment shall terminate at the
end of the first one-year renewal period that ends not less than six months
following the receipt of such notice by the non-terminating Party.
Notwithstanding the foregoing, the Term of Employment may be earlier terminated
by either Party in strict accordance with the provisions of Section 6.
 
     4.  Location of Employment.  The Executive's principal places of employment
shall be located in New York, New York and Boston, Massachusetts.
 
     5.  Compensation.
 
     5.1.  The Executive shall be paid a Base Salary, payable in accordance with
the regular payroll practices of the Company, at an annualized rate of no less
than $300,000, subject to increase as provided in the next sentence. The Base
Salary shall be reviewed for increase, in the absolute discretion of the Board
and its Compensation Committee, no less frequently than annually. In no event
shall an increase in Base Salary for any year obligate the Company to pay Base
Salary in excess of $300,000 for any subsequent year.
 
     5.2.  The Executive shall be paid an additional fixed payment of $900,000,
payable in installments of $112,500 each on the last day of each calendar
quarter, commencing March 31, 1997 and ending December 31, 1998.
 
                                        4
<PAGE>   5
 
     5.3.  For each fiscal year, in addition to the Base Salary described in
Section 5.1, the Company shall pay to the Executive an annual bonus based upon
the Pre-Tax Profit Growth Rate. For any fiscal year, (i) if the Pre-Tax Growth
Rate equals 25%, the Executive shall be entitled to receive a bonus for such
year equal to 300% of the Executive's Base Salary as in effect on such date
during the fiscal year as the Compensation Committee shall determine, provided
that such date shall be, and such determination shall be made, not later than
the 90th day of the fiscal year, or, if no date is so specified by the
Compensation Committee, as in effect on the first day of such fiscal year and
(ii) if the Pre-Tax Profit Growth Rate is less than or greater than 25%, the
Executive shall be entitled to receive a bonus for such year equal to the
percentage of the Executive's then current Base Salary determined by multiplying
(x) 300% by (y) the result obtained by dividing the Pre-Tax Profit Growth Rate
for such year by 25%. For example, if the Pre-Tax Profit Growth Rate for a
calendar year is 20%, the calculation to determine the percentage by which the
then current Base Salary shall be multiplied shall be as follows: 300% x (20% /
25%) = 240%. The annual bonus calculated in accordance with the second sentence
of this Section 5.3 for each of the years ending December 31, 1997 and December
31, 1998, shall be reduced by $450,000. Other provisions of this Section 5.3
notwithstanding, the payment of the annual bonus under this Section 5.3 shall be
made exclusively under the Company's Pay-for-Performance Incentive Plan (the
"PFPP") or another Company plan under which compensation will qualify as
"performance-based compensation" not subject to a limitation on deductibility by
the Company under Section 162(m) of the Internal Revenue Code of 1986, as
amended (the "Code"), subject to the following:
 
     (i) payment of such annual bonus shall be subject to approval of the PFPP
by the stockholders of ITGI at the 1997 Annual Meeting of Stockholders, and any
subsequent shareholder approval if and to the extent required under Code Section
162(m) in order that annual bonus amounts payable hereunder shall qualify as
"performance-based compensation" thereunder;
 
     (ii) the amount payable under this Section 5.3 shall in no event exceed the
maximum amount payable under the PFPP in respect of a performance objective
based on pre-tax net income; and
 
     (iii) the Company represents and warrants that the Compensation Committee
of the Board of Directors has irrevocably determined to exercise discretion,
exercised discretion, and/or waived any discretionary authority that the
Committee may have at any time under the PFPP to reduce the amount of, or to
take other action under the PFPP that would reduce or eliminate, the annual
bonus payable under this Section 5.3, to the fullest extent permitted by the
PFPP and Code Section 162(m).
 
     The amount of any annual bonus to which the Executive may become entitled
pursuant to the formula described in the preceding paragraph shall be determined
upon the Company's receiving audited financial statements for the year in
question, and the entire bonus due shall be paid not later than 10 days
thereafter (and in no event more than 120 days after the last day of the fiscal
year); provided, however, that the anticipated bonus may be paid to the
Executive on a monthly and quarterly basis (in accordance with the Company's
customary bonus payment policies), and may in any event be deferred at the
election of the Executive if and to the extent then permitted under any Company
deferral plan and policy; and provided, further, that, if as a result of any
monthly and quarterly payment of the Executive's anticipated bonus, the
Executive shall receive payments in excess of the total amount that is
determined, upon receipt by the Company of audited financial statements for the
year in question, to be due to him as a bonus, the Executive shall reimburse the
Company for the amount of any such excess.
 
     5.4.  The Base Salary, additional fixed payment and bonus described in this
Section 5 are gross amounts, and the Company shall be permitted to withhold from
such amounts deductions with respect to Federal, state and local taxes, FICA,
Medicare, unemployment compensation taxes or similar taxes (collectively,
"employment taxes") as required by applicable law.
 
     5.5.  The Executive shall be reimbursed for reasonable business expenses
actually incurred or paid by him in rendering the services provided for herein,
promptly upon presentation to the Company of expense statements or such other
supporting information as is consistent with the policies of the Company.
 
     5.6.  The Executive shall be entitled to participate in all Benefit Plans
of the Company on terms and conditions commensurate with his position at the
Company. The Company shall furnish the Executive with
 
                                        5
<PAGE>   6
 
appropriate office space and such other facilities and services as shall be
suitable to the Executive's position and adequate for the performance of his
duties and responsibilities as set forth in Section 2 (it being agreed that the
offices and facilities provided as of the date hereof are appropriate until the
Company relocates its principal offices). Upon execution of this Agreement, the
Executive shall be entitled to reimbursement of all reasonable legal fees
incurred by the Executive in connection with the negotiation of this Agreement
up to an amount not exceeding $62,000. Unless the Executive elects to relocate
his principal residence to the New York area, the Executive shall be entitled to
reimbursement for (i) weekly commuting expenses between his principal residence
and the New York area, (ii) the expense of hotel accommodations or a rental
apartment in the New York area and (iii) meal and other living expenses while in
the New York area. The Executive shall be entitled to five weeks paid vacation
per year.
 
     5.7.  Nothing in this Agreement shall preclude the Company from paying
other or additional compensation to the Executive.
 
     6.  Termination.
 
     6.1.  In the event that the Executive's employment hereunder is terminated,
the Executive (or the Executive's estate or other legal representative) shall be
entitled, in any event, to promptly receive (i) the Executive's Base Salary
through the date of termination, (ii) payment for accrued but unused vacation
days, (iii) any annual bonus earned, but not yet paid, with respect to years
prior to the year in which termination occurs, and (iv) other or additional
benefits in accordance with applicable plans, programs and arrangements of the
Company.
 
     6.2.  In the event that the Executive's employment hereunder is terminated
by the Company for Cause or by the Executive voluntarily without Good Reason, in
addition to the amounts and benefits to be provided pursuant to Section 6.1, the
Executive shall be entitled to continue to participate, at the Executive's cost,
in all Welfare Benefit Plans for a period of 30 days following the date of such
termination (without limiting the Executive's rights under the Comprehensive
Omnibus Reconciliation Act of 1986 ("COBRA")).
 
     6.3.  Except as provided in Section 6.4, in the event that the Executive's
employment hereunder is terminated by the Company without Cause or by the
Executive for Good Reason, in addition to the amounts and benefits to be
provided pursuant to Section 6.1, the Executive shall be entitled
 
          (i) to a lump sum payment, paid promptly upon termination, equal to
     (A) 300% of the Executive's Base Salary in effect when termination occurs,
     pro-rated through the date of termination, less (B) the sum of any bonus
     payments and additional fixed payment installments previously received by
     the Executive in respect of the year in which termination occurs (with an
     offset to the amount specified in paragraph (ii) of this Section 6.3 to the
     extent, if any, that the amount specified in clause (B) exceeds the amount
     specified in clause (A));
 
          (ii) to a lump sum payment, paid promptly upon termination, equal to
     two times the sum of (x) the Executive's annual Base Salary in effect when
     termination occurs plus (y) 300% of the Executive's Base Salary in effect
     when termination occurs;
 
          (iii) for a period of two years following the date of termination, to
     continue (without limiting the Executive's rights under COBRA) to
     participate fully, at the Company's cost, in all Welfare Benefit Plans;
 
          (iv) to make final contributions to the Jefferies Group, Inc.
     Employees' Profit Sharing Plan with respect to the payments made pursuant
     to Sections 6.3(i) and 6.3(ii), with Company contributions in accordance
     with such plan; and
 
          (v) if then permitted pursuant to any such plan, for a period of two
     years following the date of termination, to continue to participate in any
     Pension or Retirement Plan, with contributions by the Executive and the
     Company during such period being based on the Executive's being deemed to
     be receiving his annual Base Salary in effect when termination occurs and a
     bonus each year equal to 300% of such Base Salary and with continued
     vesting during such period of the Executive's entitlements under such plan.

     6.4.  In the event that, in connection with a Change in Control or during
the two-year period following a Change in Control, the Executive's employment
hereunder is terminated by the Company without Cause or by the Executive for
Good Reason, in addition to the amounts and benefits to be provided pursuant to
Section 6.1, the Executive shall be entitled
 
          (i) to a lump sum payment, paid promptly upon termination, equal to
     (A) 300% of the Executive's Base Salary in effect when termination occurs,
     pro-rated through the date of termination, less (B) the sum of any bonus
     payments and additional fixed payment installments previously received by
     the Executive in respect of the year in which termination occurs (with an
     offset to the amount specified in paragraph (ii) of this Section 6.4 to the
     extent, if any, that the amount specified in clause (B) exceeds the amount
     specified in clause (A));
 
          (ii) to a lump sum payment equal to three times the sum of (x) the
     Executive's annual Base Salary in effect when termination occurs plus (y)
     300% of the Executive's Base Salary in effect when termination occurs;
 
          (iii) for a period of three years following the date of such
     termination, to continue (without limiting the Executive's rights under
     COBRA) to participate fully, at the Company's cost, in all Welfare Benefit
     Plans;
 
          (iv) to make final contributions to the Jefferies Group, Inc.
     Employees' Profit Sharing Plan with respect to the payments made pursuant
     to Sections 6.3(i) and 6.3(ii), with Company contributions in accordance
     with such plan; and
 
          (v) if then permitted pursuant to any such plan, for a period of three
     years following the date of termination, to continue to participate in any
     Pension or Retirement Plan, with contributions by the Executive and the
     Company during such period being based on the Executive's being deemed to
     be receiving his annual Base Salary in effect when termination occurs and a
     bonus each year equal to 300% of such Base Salary and with continued
     vesting during such period of the Executive's entitlements under such plan.
 
     6.5.  In the event that the Executive's employment hereunder is terminated
due to death or Disability, in addition to the amounts and benefits to be
provided pursuant to Section 6.1, the Executive (or the Executive's estate or
other legal representative) shall be entitled to receive (and the Company shall
promptly pay to such person) a lump sum payment equal to (A) 300% of the
Executive's Base Salary in effect when termination occurs, pro-rated through the
date of termination, less (B) any bonus payments previously received by the
Executive in respect of the year in which termination occurs. If the amount
specified in clause (B) exceeds the amount specified in clause (A), the
Executive or his estate shall be obligated to repay the amount of such excess to
the Company.
 
     6.6.  In the event of termination of the Executive's employment hereunder
for Disability, in addition to the amounts and benefits to be provided pursuant
to Sections 6.1 and 6.5, the Executive shall be entitled, through the age of 65,
 
          (i) to receive, no less frequently than monthly, periodic disability
     payments at a rate equal to 60% of the Executive's Base Salary in effect at
     the time of termination for Disability and
 
          (ii) to continue to participate fully, at the Company's cost, in all
     Welfare Benefit Plans (without limiting the Executive's rights under
     COBRA).
 
The periodic disability payments required under clause (i) of the preceding
sentence shall be reduced by any disability benefits provided to the Executive
(other than benefits attributable to the Executive's own contributions) under
any disability insurance program of the Company in effect during such period.
 
     6.7.  Any payment under Section 5.2 or this Section 6 that is based on Base
Salary shall be determined disregarding any reduction in Base Salary that would
constitute Good Reason for termination.
 
                                        7
<PAGE>   8
 
     6.8.  In the event that any Welfare Benefit Plan referred to in Sections
6.3(iii), 6.4(iii) or 6.6(ii) does not permit, as required by those Sections,
continued full participation by the Executive after his termination, then the
Company shall promptly provide the Executive the after-tax economic equivalent
of any coverage or other benefit foregone. The after-tax economic equivalent of
any coverage or other benefit foregone shall be deemed to be no less than the
total cost, determined on an after-tax basis, to the Executive of obtaining such
foregone coverage or other benefit.
 
     6.9.  A termination by the Company, other than for death, Disability or
Cause and other than pursuant to a notice of non-renewal given in accordance
with Section 3, shall be effective 30 days after the Executive receives written
notice thereof from the Company and shall not be deemed a breach of this
Agreement. A voluntary termination by the Executive, other than for Good Reason
and other than pursuant to a notice of non-renewal given in accordance with
Section 3, shall be effective 30 days after the Executive gives written notice
thereof to the Company and shall not be deemed a breach of this Agreement. A
termination for death shall be effective on the date of death. No termination of
the Executive's employment, other than a termination due to death, shall be
effective before the terminating Party gives the other Party written notice of
termination identifying the grounds for the termination.
 
     6.10.  No termination for Cause shall take effect unless the provisions of
this Section 6.10 shall have been complied with. The Board shall give the
Executive written notice of its intention to terminate him for Cause, such
notice (A) to state in detail the particular circumstances that constitute the
grounds on which the proposed termination for Cause is based and (B) to be given
within six months of the Board learning of such circumstances. The Executive
shall have 15 days after receiving such written notice in which to cure such
grounds, to the extent such cure is possible. If he fails to cure such grounds
to the Board's satisfaction, the Executive shall then be entitled to a hearing
before the Board. Such hearing shall be held within 20 days of his receiving
such notice, provided he requests a hearing within 10 days of receiving the
notice. If, within 5 days following such hearing, the Board gives written notice
to the Executive confirming that, in its judgment, Cause for terminating him on
the basis set forth in the original notice exists, he shall thereupon be
terminated for Cause, subject to de novo review in accordance with the
provisions of Section 19, it being understood that the Executive shall have no
entitlements on account of such termination to any amounts or benefits following
the date of such termination except as provided in Sections 6.1, 6.2, 7 and 8.
At any time while the procedure set forth in this Section 6.10 is being carried
out, the Company may place the Executive on leave, during which he shall
continue to receive all of his entitlements under this Agreement.
 
     6.11.  No termination for Good Reason shall take effect unless the
provisions of this Section 6.11 shall have been complied with. The Executive
shall give the Company written notice of his intention to terminate for Good
Reason, such notice (A) to state in detail the particular circumstances that
constitute the grounds on which the proposed termination for Good Reason is
based and (B) to be given within six months of the Executive learning of such
circumstances. The Company shall have 15 days after receiving such written
notice in which to cure such grounds, to the extent such cure is possible. If
the Company fails to cure such grounds to the Executive's satisfaction, the
Company shall then be entitled to present its position to the Executive. Such
presentation shall take place within 20 days of the Company's receiving such
notice, provided it requests the opportunity to make such a presentation within
10 days of receiving the notice. If, within 5 days following such presentation,
the Executive gives written notice to the Company confirming that, in his
judgment, Good Reason on the basis set forth in the original notice exists, his
employment shall thereupon terminate for Good Reason, subject to de novo review
in accordance with the provisions of Section 19. At any time while the procedure
set forth in this Section 6.11 is being carried out, the Company shall, at the
Executive's request, place the Executive on leave, during which he shall
continue to receive all of his entitlements under this Agreement.
 
     6.12.  There shall be no reduction in any lump sum payment made to the
Executive pursuant to this Agreement because such lump sum payment is required
to be made prior to the date on which payments to which the lump sum relates
would normally be made.
 
     6.13.  In the event of any termination of employment under this Section 6,
the Executive shall be under no obligation to seek other employment and there
shall be no offset against amounts due the Executive under
 
                                        8
<PAGE>   9
 
this Agreement on account of (i) any remuneration or other benefit attributable
to any subsequent employment that he may obtain except as specifically provided
in this Section 6 or (ii) any claims that the Company, or any of its Affiliates,
may have against the Executive, provided that if the Executive receives coverage
from a subsequent employer at least equivalent to the coverage afforded to him
under any Welfare Benefit Plan, the Company shall cease to be obligated to
provide such coverage.
 
     6.14.  Any amounts due under this Section 6 are in the nature of severance
payments considered to be reasonable by the Company and are not in the nature of
a penalty. The amounts and benefits provided for in Section 6.3 and 6.4
(including the amounts and benefits provided for in Section 6.1 and incorporated
in Section 6.3 and 6.4), together with the Executive's rights under Sections 7
and 8, shall constitute the Executive's exclusive entitlements to payments and
benefits on account of the termination of his employment by the Company without
Cause or by the Executive for Good Reason.
 
     7.  Gross-up Payments.
 
     7.1.  Anything in this Agreement to the contrary notwithstanding, in the
event it shall be determined that any payment, distribution or other benefit
(including, without limitation, any acceleration of vesting of any benefit) that
is, or may be, provided to or for the benefit of the Executive and that is
contingent on a change in the ownership or control of the Company or in the
ownership of the assets of the Company within the meaning of Section 280G of the
Code and the regulations thereunder (a "Payment") (whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise, but determined without regard to any Gross-up Payment required under
this Section 7) would be subject to the excise tax imposed by Section 4999 of
the Code (such excise tax, together with any interest and penalties imposed in
respect thereto, hereinafter collectively referred to as the "Excise Tax"), then
the Executive shall be entitled to receive a payment (a "Gross-Up Payment") in
an amount that after payment by the Executive of all taxes, including, without
limitation, any income, employment, and excise taxes (and any interest and
penalties imposed with respect thereto), imposed upon the Gross-Up Payment
leaves the Executive a net amount from the Gross-Up Payment equal to the Excise
Tax imposed upon the Payment.
 
     7.2.  Subject to the provisions of Section 7.3, all determinations required
to be made under this Section 7, including whether and when a Gross-Up Payment
is required and the amount of such Gross-Up Payment and the assumptions to be
utilized in arriving at such determination, shall be made by a public accounting
firm selected in accordance with the following two sentences (the "Accounting
Firm") which shall provide detailed supporting calculations both to the Company
and the Executive within fifteen (15) business days of the receipt of notice
from the Executive that there has been a Payment, or such earlier time as is
requested by the Company (collectively, the "Determination"). The Accounting
Firm shall be a nationally based public accounting firm selected by mutual
agreement of the Parties. If the Parties cannot agree on a single such firm to
serve as the Accounting Firm, each Party shall choose one nationally based
public accounting firm and the two firms thus chosen shall select a single
nationally based public accounting firm to serve as the Accounting Firm. All
fees and expenses of any Accounting Firm, and of any accounting firm chosen by
either Party pursuant to the preceding sentences to select the Accounting Firm,
shall be borne solely by the Company. Any Gross-Up Payment, as determined
pursuant to this Section 7, shall be paid by the Company to the Executive within
five (5) days of the receipt of the Determination. If the Accounting Firm
determines that no Excise Tax is payable by the Executive, it shall furnish the
Executive with a written opinion that failure to report the Excise Tax on the
Executive's applicable federal income tax return will not result in the
imposition of a negligence or similar penalty. The Determination by the
Accounting Firm shall be binding upon the Company and the Executive. In the
event the Company exhausts, or fails to pursue, its remedies pursuant to Section
7.3 and the Executive thereafter is required by a determination of a court or
the Internal Revenue Service to make payment of any Excise Tax, the Accounting
Firm shall determine promptly following receipt of such determination the amount
of the Gross-Up Payment that should have been made by the Company (the
"Underpayment") and any such Underpayment shall be paid promptly by the Company
to or for the benefit of the Executive.
 
     7.3.  The Executive shall notify the Company in writing of any claim by the
Internal Revenue Service that, if successful, would require the payment by the
Company of the Gross-Up Payment. Such notification
 
                                        9
<PAGE>   10
 
shall be given as soon as practicable but no later than ten (10) business days
after the Executive is informed in writing of such claim and shall apprise the
Company of the nature of such claim and the date on which such claim is
requested to be paid. The Executive shall not pay such claim prior to the
expiration of the 30-day period following the date on which the Executive gives
such notice to the Company (or such shorter period ending on the date that any
payment of taxes with respect to such claim is due). If the Company notifies the
Executive in writing prior to the expiration of such period that it desires to
contest such claim, the Executive shall:
 
          (i) give the Company any information reasonably requested by the
     Company relating to such claim,
 
          (ii) take such action in connection with contesting such claim as the
     Company shall reasonably request in writing from time to time, including,
     without limitation, accepting legal representation with respect to such
     claim by an attorney reasonably selected by the Company,
 
          (iii) cooperate with the Company in good faith in order effectively to
     contest such claim, and
 
          (iv) permit the Company to participate in any proceeding relating to
     such claim; provided, however, that the Company shall bear, and promptly
     pay, all costs and expenses (including without limitation additional
     interest and penalties and the cost of the Executive's legal counsel)
     incurred in connection with such contest and shall indemnify and hold the
     Executive harmless, on an after-tax basis, for any Excise Tax (including,
     without limitation, interest and penalties with respect thereto) imposed as
     a result of such proceeding and payment of costs and expenses. Without
     limitation on the foregoing provisions of this Section 7.3, the Company
     shall control all proceedings taken in connection with such contest and, at
     its sole option, may pursue or forego any and all administrative appeals,
     proceedings, hearings and conferences with the taxing authority in respect
     of such claim and may, at its sole option, either direct the Executive to
     pay the tax claimed and sue for a refund or contest the claim in any
     permissible manner, and the Executive agrees to prosecute such contest to a
     determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Company shall
     determine; provided further, that if the Company directs the Executive to
     pay such claim and sue for a refund, the Company shall advance the amount
     of such payment to the Executive on an interest-free basis and shall
     indemnify and hold the Executive harmless, on an after-tax basis, from any
     Excise Tax (including interest or penalties with respect thereto) imposed
     with respect to such advance or with respect to any imputed income with
     respect to such advance; and provided further, that any extension of the
     statute of limitations relating to payment of taxes for the taxable year of
     the Executive with respect to which such contested amount is claimed to be
     due is limited solely to such contested amount. Furthermore, the Company's
     control of the contest shall be limited to issues with respect to which a
     Gross-Up Payment would be payable hereunder and the Executive shall be
     entitled to settle or contest, as the case may be, any other issue raised
     by the Internal Revenue Service or any other taxing authority.
     Notwithstanding anything to the contrary in this Section 7.3, the Company
     shall not be obligated to pay any costs or expenses that are fairly
     allocable to any such other issue.
 
     7.4.  If, after the receipt by the Executive of an amount advanced by the
Company as a Gross-Up Payment pursuant to Section 7.3, the Executive becomes
entitled to receive, and receives, any refund with respect to such claim, the
Executive shall (subject to the Company's complying with the requirements of
Section 7.3) promptly pay to the Company the amount of such refund (together
with any interest paid or credited thereon after taxes applicable thereto). If,
after the receipt by the Executive of an amount advanced by the Company pursuant
to Section 7.3, a determination is made that the Executive shall not be entitled
to any refund with respect to such claim and the Company does not notify the
Executive in writing of its intent to contest such denial of refund prior to the
expiration of thirty (30) days after such determination, then such advance shall
be forgiven and shall not be required to be repaid and the amount of such
advance shall offset, to the extent thereof, the amount of Gross-Up Payment
required to be paid.
 
     8.  Stock Option.
 
     8.1.  On March 26, 1997, the Company granted to the Executive a
nonqualified stock option (the "Option") to purchase 1,000,000 shares of Common
Stock of the Company, for a price per share equal to
 
                                       10
<PAGE>   11
 
$22.175. The Option is intended to be a nonqualified stock option and shall not
be treated as an incentive stock option under the provisions of the Code.
 
     8.2.  The Option has been granted pursuant to the Company's 1994 Stock
Option and Long-Term Incentive Plan, as amended and restated (the "1994 Plan").
The grant of the Option is subject to approval of the 1994 Plan by the
stockholders of ITGI at the 1997 Annual Meeting of Stockholders. The Company
represents and warrants that the Option conforms to and is consistent with the
terms of the 1994 Plan.
 
     8.3.  The Option has been granted for no consideration other than the
services of the Executive and in contemplation of the Executive's agreements set
forth herein. The Company has taken all necessary actions so that the grant of
the Option is exempt from the provisions of Section 16(b) of the 1934 Act.
 
     8.4.  Except as otherwise expressly provided herein, the Option shall
become exercisable as to 200,000 shares on May 4, 1997, and thereafter as to an
additional 200,000 shares on each subsequent December 10; provided, that, (i) in
the event that the Moving 10-Day Average Closing Price of the Common Stock shall
at any time exceed $50 per share, any then unexercised portion of the Option
shall immediately become exercisable in full; and provided, further, that, (ii)
immediately prior to any Option-related Change in Control, any then unexercised
portion of the Option shall become exercisable in full.
 
     8.5.  The Company shall use its best efforts so that, on or prior to May 4,
1997, all Option Shares received by the Executive on any exercise of the Option
shall be, and shall remain, (1) fully registered (at the Company's expense)
under the Securities Act of 1933, as amended (the "1933 Act"), both for issuance
and for resale, pursuant to a registration on Form S-8 under the 1933 Act that
contains a separate reoffer prospectus prepared in accordance with the
requirements of Part I of Form S-3 or such alternative or successor procedure
that provides comparable opportunity under the 1933 Act for issuance and resale;
(2) fully registered or qualified (at the Company's expense), or exempt from
registration and qualification, under such state securities laws as the
Executive may reasonably request, both for issuance and for resale; and (3)
listed on a national securities exchange or eligible for sale on the Nasdaq
National Market unless, in each case, the Executive consents in writing to
alternative arrangements that adequately protect the saleability of the Option
Shares in the public market, which consent shall not be unreasonably withheld,
and unless, in the case of listing on a national securities exchange or
eligibility for sale on the Nasdaq National Market, the Company cannot, with
reasonable best efforts, maintain such listing or eligibility. Notwithstanding
anything to the contrary in this Section 8.5, in no event shall the Company be
obligated to file a registration on Form S-1 or any successor to Form S-1.
 
     8.6.  In the event of the termination of the Executive's employment
hereunder, the following provisions shall apply:
 
          (A) In the event that the Executive's employment hereunder is
     terminated by the Company for Cause or by the Executive voluntarily without
     Good Reason, the Executive shall forfeit the then unexercisable portion of
     the Option, and the then exercisable portion shall remain exercisable as
     provided in Section 8.7;
 
          (B)  In the event that the Executive's employment hereunder is
     terminated by the Company without Cause or by the Executive voluntarily
     with Good Reason, the then unexercisable portion of the Option shall become
     exercisable, and shall remain exercisable as provided in Section 8.7;
 
          (C)  In the event that the Executive's employment hereunder is
     terminated for death, the portion (if any) of the Option that would have
     become exercisable on or before the next anniversary of the Effective Date
     following the date of termination shall become exercisable, and shall
     remain exercisable as provided in Section 8.7; and
 
          (D)  In the event that the Executive's employment hereunder is
     terminated for Disability, the portion (if any) of the Option that would
     have become exercisable on or before the next anniversary of the Effective
     Date following the date of termination shall become exercisable ratably
     (based on the portion of the year elapsing before the termination for
     Disability), and shall remain exercisable to that extent as provided in
     Section 8.7.
 
                                       11
<PAGE>   12
 
     8.7.  The Option (to the extent not earlier exercised or forfeited) shall
expire at the earlier of (i) 11:59 p.m., Eastern time, on January 5, 2002; (ii)
24 months following the termination of the Executive's employment hereunder if
such termination is for death or Disability; and (iii) 60 days following
termination of the Executive's employment hereunder if such termination is by
the Company for Cause or by the Executive voluntarily without Good Reason,
provided, that, the Option shall not expire pursuant to clauses (ii) or (iii) of
this Section 8.7 if, prior to the date of the Executive's termination, an
Option-related Change in Control shall have occurred.
 
     8.8.  Written notice of exercise of the Option shall be given to the
Secretary of the Company and shall be deemed to have been received either when
delivered personally to the office of the Secretary or at 11:58 p.m. on the date
of any U.S. Postal Service postmark on the notice, whichever is earlier (the
"Exercise Date"). Such notice shall be irrevocable and must be accompanied by
the payment of the purchase price as provided in Section 8.9 below. Upon the
exercise of the Option, the Company shall transfer or shall cause to be issued a
certificate or certificates for the Common Stock being purchased as promptly as
practicable. The Option (to the extent otherwise exercisable) may be exercised
in whole or in part, at the Executive's election.
 
     8.9.  The purchase price of Option Shares being acquired shall be paid in
full to the Company at the time of such exercise in cash (including by check) or
by the surrender of Common Stock (valued at the Average 5-Day Closing Price of
the Company's Common Stock on the date of exercise) or a combination thereof,
provided that Common Stock held for less than six months may be surrendered only
with the prior approval of the Compensation Committee or the Board (which
approval shall not be unreasonably withheld). In addition, any part of the
exercise price of any Option and any related tax withholding amount may, with
the prior approval of the Compensation Committee or the Board (which approval
shall not be unreasonably withheld), be paid through a cashless exercise
procedure that affords the Executive the opportunity to sell immediately some or
all of the shares underlying the exercised portion of the Option in the public
market in order to generate sufficient cash to pay the Option exercise price
and/or to satisfy tax withholding obligations relating to the Option. The
Compensation Committee or the Board shall not be deemed to have unreasonably
withheld approval of a cashless exercise procedure if such cashless exercise
would result in ITGI's being required to recognize compensation expense that it
would otherwise not be required to recognize.
 
     8.10.  In the event of any merger, consolidation, reorganization,
recapitalization, stock dividend, other extraordinary dividend or other change
in corporate structure or capitalization affecting the Common Stock of the
Company, the Compensation Committee shall make appropriate adjustments in the
$50 per share price referred to Section 8.4(i), in the number or kind of equity
securities subject to the Option and/or in the exercise price or other terms and
conditions of the Option, or appropriate provision for supplemental payments of
cash or other property, so as to prevent dilution or enlargement of the rights
of the Executive and of the after-tax economic opportunity and value represented
by the Option; provided, that, any such adjustment or provision (or any refusal
to make such an adjustment or provision) shall be subject to de novo review in
accordance with Section 19; and, provided, further, that, no adjustment in
exercise price shall be made on account of any cash dividend that is not a
large, special and non-recurring dividend.
 
     8.11. The Executive represents and warrants that he is acquiring the Option
for his own account and not with a view to distribution of the Option or the
Option Shares.
 
     8.12. Neither the Executive nor any other person shall have any right to
commute, sell, assign, transfer, pledge, anticipate, mortgage or otherwise
encumber, transfer, hypothecate or convey the Option, which is expressly
declared to be unassignable and nontransferable, other than by will or under the
laws of descent and distribution. No part of the Option or of any amounts
payable pursuant to the provisions of this Agreement shall be subject to seizure
or sequestration for the payment of any debts, judgments, alimony or separate
maintenance owed by the Executive or any other person, nor be transferable by
operation of law in the event of the Executive's or any other person's
bankruptcy or insolvency.
 
     8.13.  Neither the Executive nor any other person shall acquire by reason
of the Option or the Option Shares any right in or title to any assets, funds or
property of the Company whatsoever including, without limiting the generality of
the foregoing, any specific funds or assets which the Company, in its sole
discretion, may set aside in anticipation of a liability. No trust shall be
created in connection with or by the granting of the
 
                                       12
<PAGE>   13
 
Option or the purchase of any Option Shares, and any benefits which become
payable hereunder shall be paid from the general assets of the Company. The
Executive shall have only a contractual right to the amounts, if any, payable
pursuant to this Agreement, unsecured by any assets of the Company or any of its
Affiliates.
 
     8.14.  Nothing herein will limit the Company's right to issue Common Stock,
or options or other rights to purchase Common Stock, subject to vesting,
expiration and other terms and conditions deemed appropriate by the Company and
its Affiliates.
 
     8.15.  The Executive authorizes the Company to withhold, in accordance with
applicable law, from any compensation payable to him any taxes required to be
withheld by federal, state or local law in connection with the issuance of
Option Shares on any exercise of the Option. The Executive may elect to have the
Company withhold Option Shares to pay any applicable withholding taxes resulting
from the exercise of the Option in accordance with regulations of the
Compensation Committee then in effect.
 
     8.16.  It is the intention of the Parties that, if Jefferies Group, Inc.
(including, for purposes of this Section 8.16 only, any successor to Jefferies
Group, Inc. as controlling shareholder of the Company) shall sell to a third
party any equity securities of the Company at a time when the Executive holds
(i) Option Shares or (ii) current rights to acquire Option Shares through
exercise of the Option, Jefferies Group, Inc. shall require the purchaser of its
equity securities of the Company to purchase, at the election of the Executive,
a proportion of the aggregate of such Option Shares held, or acquirable, by him
that equals (x) the proportion of the aggregate equity securities of the Company
then held by Jefferies Group, Inc. that the third party is purchasing or (y)
such lesser proportion as the Executive may elect, it being understood that if
the third party does not wish to purchase additional equity securities of the
Company, Jefferies Group, Inc. shall reduce the number of equity securities
being sold by it so that the Executive may sell the number of Option Shares
determined in accordance with this sentence. It is also the intention of the
Parties that the purchase from the Executive shall be made on the same terms and
for the same consideration as the purchase from Jefferies Group, Inc. The
Company shall use its best efforts to enter into an appropriate agreement with
Jefferies Group, Inc., for the benefit of the Executive, to carry out the intent
of the two preceding sentences.
 
     8.17.  In the event of any Option-related Change in Control transaction in
which holders of Common Stock of the Company receive cash, securities or other
property for their Common Stock, the Company shall enable the Executive (if he
so elects) to exercise the Option (in whole or in part) and to receive in
exchange for any Option Shares thus or otherwise acquired the same consideration
as is received in such Option-related Change in Control transaction by other
holders of Common Stock.
 
     8.18.  If at any time there is an underwritten public offering of the
Company's equity securities, the Company shall use its reasonable best efforts
to cause to be included in the underwritten offering such Option Shares as the
Executive may elect, provided that if the underwriters determine that the
addition of the Option Shares would jeopardize the success of the offering, the
Option Shares shall not be included.
 
     9.  Non-Competition.
 
     9.1.  In the event that the Executive's employment hereunder is terminated
by the Company without Cause or by the Executive for Good Reason, in
consideration for the payments to be made under Section 6, the Executive agrees
that he shall not for a period of eighteen months from the date of such
termination engage in any activity, either as a principal or employee, that
competes directly and substantially with the Company in any business in which
the Company is engaged at the time of such termination unless the revenues
realized by the Company from such business during the fiscal year immediately
preceding such termination are less than 5% of the Company's revenues for such
year.
 
     9.2.  The Executive agrees that if his employment terminates under
circumstances other than those described in Section 9.1, he shall not, for a
period of six months from the date of such termination, engage in any activity,
either as a principal or employee, that competes directly and substantially with
the Company in any business in which the Company is engaged at the time of such
termination unless the revenues realized by the Company from such business
during the fiscal year immediately preceding such termination are less than 5%
of the Company's revenues for such year.
 
                                       13
<PAGE>   14
 
     9.3  Nothing in this Section 9 shall preclude the Executive from owning
equity securities of any publicly held company or enterprise, provided that the
Executive does not own more than 3% of the equity securities of any such company
or enterprise.
 
     9.4.  For a period of 12 months following termination of the Executive's
employment hereunder, the Executive shall not, whether for his own account or
for the account of any other individual, corporation, partnership, firm, joint
venture, sole proprietorship or other entity (other than the Company or its
affiliates), intentionally solicit, endeavor to entice away from the Company, or
otherwise intentionally interfere with the relationship of the Company with, any
of their employees.
 
     9.5.  The Executive hereby acknowledges and agrees that the services to be
performed by him hereunder are of a special, unique, unusual, extraordinary and
intellectual character that gives them a peculiar value, and that the
restrictions contained in this Section 9 are reasonable and necessary to protect
the legitimate interests of the Company. The Executive further acknowledges and
agrees that the breach by him of this Section 9 may not reasonably or adequately
be compensated in damages and that, in the event of any such breach or
threatened breach, and in addition to all other rights or remedies, the Company
shall be entitled to seek equitable relief, including but not limited to
enforcing the specific performance of this Agreement by the Executive, or
enjoining or restraining the Executive from any breach or threatened breach of
this Agreement. Except as provided in the last sentence of Section 6.14, no
remedy conferred by any of the specific provisions of this Agreement is intended
to be exclusive of any other remedy, and each and every remedy shall be
cumulative and shall be in addition to every other remedy given hereunder or now
or hereafter existing at law or in equity or by statute or otherwise.
 
     9.6.  The obligations of the Executive under this Section 9 are conditioned
on the Company fully and promptly satisfying all of its obligations under
Section 6.
 
     10.  Indemnification.
 
     10.1.  The Company agrees that (i) if the Executive is made a party, or is
threatened to be made a party, to any Proceeding by reason of the fact that he
is or was a director, officer, employee, agent, manager, consultant or
representative of the Company or is or was serving at the request of the Company
as a director, officer, member, employee, agent, manager, consultant or
representative of another person, or (ii) if any Claim is made, or is threatened
to be made, that arises out of or relates to the Executive's service in any of
the foregoing capacities, then the Executive shall promptly be indemnified and
held harmless by the Company to the fullest extent permitted or authorized by
the Company's certificate of incorporation, bylaws or Board resolutions or, if
greater, by the laws of the State of Delaware or by other applicable law,
against any and all costs, expenses, liabilities and losses (including, without
limitation, reasonable attorney's fees, judgments, interest, expenses of
investigation, fines, ERISA excise taxes or penalties and amounts paid or to be
paid in settlement) incurred or suffered by the Executive in connection
therewith, and such indemnification shall continue as to the Executive even if
he has ceased to be a director, member, employee, agent, manager, consultant or
representative of the Company or other person, and shall inure to the benefit of
the Executive's successors and assigns. The Company shall advance to the
Executive all costs and expenses incurred by him in connection with any such
Proceeding or Claim within 15 days of receiving written notice requesting such
an advance. Such notice shall include an undertaking by the Executive to repay
the amount of such advance if he is ultimately and conclusively determined not
to be entitled to indemnification against such costs or expenses.
 
     10.2.  Solely for the purposes of this Agreement, neither the failure of
the Company (including its Board, independent legal counsel or stockholders) to
have made a determination in connection with any request for payment or
advancement under Section 10.1 that the Executive has satisfied any applicable
standard of conduct, nor a determination by the Company (including its Board,
independent legal counsel or stockholders) that the Executive has not met any
applicable standard of conduct, shall create a presumption that the Executive
has not met an applicable standard of conduct.
 
     10.3.  The Company shall at all times during the Term of Employment and for
two years thereafter keep in place directors and officers' liability insurance
policy covering the Executive to the extent that the Company
 
                                       14
<PAGE>   15
 
provides such coverage for other senior executives, provided that such coverage
is available on a commercially reasonable basis.
 
     11.  Assignability; Binding Nature.
 
     This Agreement shall be binding upon and inure to the benefit of the
Parties and their respective successors and assigns. No rights or obligations of
the Company under this Agreement may be assigned or transferred by the Company
except that such rights or obligations may be assigned or transferred pursuant
to a merger or consolidation in which the Company is not the continuing entity,
or the sale or liquidation of all or substantially all of the assets of the
Company, provided that the assignee or transferee is the successor to all or
substantially all of the assets of the Company and such assignee or transferee
expressly assumes all the liabilities, obligations and duties of the Company as
contained in this Agreement. In connection with any transfer or assignment of
its rights, duties, or obligations under this Agreement, the Company shall take
whatever action it legally can to cause such assignee or transferee to expressly
assume the liabilities, obligations and duties of the Company hereunder unless
such assumption occurs as a matter of law. If the Company survives such
transaction as a continuing entity, it shall, in any event, remain as
unconditional guarantor of prompt payment and prompt satisfaction of all such
liabilities, obligations and duties. No rights, obligations or duties of the
Executive under this Agreement may be assigned or transferred, other than his
rights to compensation and benefits, which may be transferred only by will or
operation of law, except as otherwise expressly provided in this Agreement.
 
     12.  Representations.
 
     The Company represents and warrants that it is fully authorized and
empowered by action of the Board to enter into this Agreement; that the
performance of its obligations under this Agreement will not violate any law,
regulation or order currently in effect or any agreement, plan or corporate
governance document of the Company currently in effect; and that the Company has
taken all reasonable steps (including appropriate approval by a properly
constituted Compensation Committee or by the Board) to qualify the grant of the
Option under Section 8 for exemption from the requirements of Section 16(b) of
the 1934 Act. The Executive represents and warrants that he has the capacity to
enter into this Agreement and that the performance of his obligations under this
Agreement will not violate any law, regulation or order currently in effect or
any agreement binding upon him and currently in effect.
 
     13.  Entire Agreement.
 
     This Agreement contains the entire understanding and agreement between the
Parties concerning the subject matter hereof and supersedes all prior
agreements, understandings, discussions, negotiations and undertakings, whether
written or oral, between the Parties with respect thereto.
 
     14.  Amendment or Waiver.
 
     No provision in this Agreement may be amended unless such amendment is set
forth in a writing signed by the Parties. No waiver by either Party of any
breach of any condition or provision contained in this Agreement shall be deemed
a waiver of a similar or dissimilar condition or provision at the same or any
prior or subsequent time. To be effective, any waiver must be set forth in
writing and signed by the waiving Party.
 
     15.  Severability.
 
     In the event that any provision or portion of this Agreement shall be
determined to be invalid or unenforceable for any reason, in whole or in part,
the remainder of this Agreement shall be unaffected thereby and shall remain in
full force and effect to the fullest extent permitted by law so as to achieve
the purposes of this Agreement.
 
     16.  Survivorship.
 
     Except as otherwise expressly set forth in this Agreement, the respective
rights and obligations of the Parties hereunder shall survive any termination of
the Executive's employment until fully performed, it being understood that all
of the Executive's entitlements to payments and benefits under this Agreement on
account of the termination of his employment are set forth in Sections 6, 7 and
8. This Agreement itself (as
 
                                       15
<PAGE>   16
 
distinguished from the Executive's employment hereunder) may not be terminated
without the written consent of both Parties.
 
     17.  Beneficiaries/References.
 
     The Executive shall be entitled, to the fullest extent permitted by law, to
select and to change a beneficiary or beneficiaries to receive any compensation
or benefit hereunder following the Executive's death, by giving written notice
to the Company. In the event of the Executive's death or a judicial
determination of his incompetence, references in this Agreement to the Executive
shall be deemed, where appropriate, to refer to his beneficiary, estate or other
legal representative.
 
     18.  Governing Law/Jurisdiction.
 
     Except as otherwise expressly provided herein, this Agreement shall be
governed, construed, interpreted, performed and enforced in accordance with the
laws of the State of New York, without reference to principles of conflict of
laws.
 
     19.  Resolution of Disputes.
 
     Any controversy or Claim arising out of or relating to this Agreement, any
amendment thereof, or the Executive's service with the Company (excluding any
Proceeding that is initiated pursuant to Section 9.5 and that is limited solely
to seeking equitable relief), shall, at the election of either Party, be
resolved by arbitration, to be held in New York, New York, before the NASD or
any exchange of which ITG is a member in accordance with the rules of such
entity then in effect. Judgment upon the award of the arbitrator(s) may be
entered in any court having jurisdiction thereof. The fees of the arbitrator(s)
shall be borne by the Company and each Party shall bear his or its own costs and
expenses (including, without limitation, attorneys' fees) relating to any such
controversy or Claim, or to any Proceeding brought pursuant to Section 9.5,
provided that if the Executive substantially prevails in such arbitration or
Proceeding, the Company shall reimburse him for such costs and expenses. Pending
the final and conclusive resolution of any such controversy, Claim, or
Proceeding, the Company shall continue prompt payment of all amounts due the
Executive under this Agreement (or any amendment thereof) and prompt provision
of all benefits to which the Executive or his successors and assigns are
entitled.
