                               PROSPECTUS SUMMARY

    YOU SHOULD READ THE FOLLOWING SUMMARY TOGETHER WITH THE MORE DETAILED
INFORMATION REGARDING OUR COMPANY, THE COMMON STOCK BEING SOLD IN THIS OFFERING
AND OUR CONSOLIDATED FINANCIAL STATEMENTS, INCLUDING THE NOTES TO THOSE
STATEMENTS, APPEARING ELSEWHERE IN THIS PROSPECTUS.

                                  OUR BUSINESS

    We are a leading provider of solutions for global trade management. Our
offerings include an extensive online library of global trade content, web-based
business-to-business, or B2B, solutions, management consulting and solution
services. Global trade involves the physical movement of goods across country
borders, the management of information and processes required to enable global
trade and the financial exchange processes required to complete related
transactions. Our solutions focus on the management of information required to
enable global trade and enhance collaboration across a client's global trade
network. Our primary Internet-based delivery mechanism for our solutions is our
web-based portal, TradePrism.com.

    Forrester Research estimates that B2B commerce will grow from approximately
$406 billion in 2000 to approximately $2.7 trillion in 2004, forcing many
companies to streamline and automate their trading practices. The Internet
allows businesses to penetrate global markets effectively. We believe that while
many companies have invested in the technologies to help streamline and automate
business practices for their domestic operations, they continue to operate
inefficiently across global supply chains or lose new market opportunities
entirely. For example, Forrester Research estimates that over 46% of
Internet-based orders to the U.S. from international clients go unfilled because
companies lack the procedures to fill them.

    The modern global marketplace is a fast-paced, complex trade network that
includes exporters, forwarders, carriers, brokers, importers, banks and customs
and regulatory agencies. As a result, the resources and expertise necessary to
manage global trade have increased significantly. Today, companies need access
to:

    - comprehensive, up-to-date and Internet-accessible global trade content
      (regulations, data and documentation required to execute cross-border
      transactions);

    - software applications that automate cross-border B2B and
      business-to-consumer, or B2C, transactions; and

    - reliable global trade expertise and advice to optimize their global trade
      practices.

    We believe that we are the only company offering a comprehensive suite of
global trade management solutions that addresses all of these needs. Our
offerings enable companies to leverage our extensive and actively managed
library of country-specific trade requirements to improve their global trade
operations. Our comprehensive suite of web-based, B2B solutions enables clients
to automate and optimize information management procedures across their entire
global trade network. These solutions also address the needs of multiple members
of this network and enable collaboration among all of its participants. Our
management consulting services assist companies in analyzing and addressing
their global trade practices and opportunities. We also provide solution
services that enable clients to outsource their trade management procedures in
order to focus on their core competencies and realize financial benefits
associated with efficient and effective global trade management.

    We serve an international client base of over 200 companies, including Dell,
Lucent, Microsoft, the New Zealand Dairy Board, Nike, Nortel, Robert Bosch and
Silicon Graphics. Our clients currently utilize our solutions to ship to over
120 countries worldwide. We also provide integrated B2B solutions for vertical
Internet trading markets such as Arzoon.com, CatalogCity.com, RightFreight.com
and SupplierMarket.com and are continuing to develop our B2B solutions to meet
the needs of specific vertical industries. To facilitate the marketing and
delivery of our solutions, we also maintain relationships with a number of
leading technology companies, including IBM, JD Edwards, Oracle and Sun
Microsystems.

                                  RISK FACTORS

    THIS OFFERING AND YOUR INVESTMENT IN OUR COMMON STOCK INVOLVE A HIGH DEGREE
OF RISK. YOU SHOULD CAREFULLY CONSIDER THE FOLLOWING RISKS AND ALL OTHER
INFORMATION CONTAINED IN THIS PROSPECTUS BEFORE PURCHASING OUR COMMON STOCK. IF
ANY OF THE FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS, FINANCIAL CONDITION AND
RESULTS OF OPERATIONS COULD BE MATERIALLY AND ADVERSELY AFFECTED, THE VALUE OF
OUR STOCK COULD DECLINE, AND YOU MAY LOSE ALL OR PART OF YOUR INVESTMENT. THE
RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY ONES WE FACE.
ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY KNOWN TO US OR THAT WE
CURRENTLY DEEM IMMATERIAL ALSO MAY IMPAIR OUR BUSINESS OPERATIONS.

                         RISKS RELATED TO OUR BUSINESS

OUR FUTURE SUCCESS IS UNCERTAIN BECAUSE OUR WEB-BASED SOLUTIONS ARE UNPROVEN,
HAVE ONLY BEEN RECENTLY DEVELOPED OR ARE CURRENTLY IN DEVELOPMENT.

    We have recently commercially released our TradeSphere solutions, our
web-based suite of products and services developed from our existing global
trade management solutions. Our web-based portal, TradePrism.com, is also
currently in the development stage. Because our portal and many of our
TradeSphere modules are in the early stages of development, there can be no
assurance that they will be successfully integrated into our web-based B2B
solutions. Many of these solutions require further product development to
achieve our expected level of functionality. If we fail to successfully complete
this development or if the market does not commercially accept our solutions
once they are fully developed, our business would be adversely impacted.

    Furthermore, because our web-based solutions are in their early stages of
development, we have limited insight into trends that may emerge and affect our
business. We face many challenges, risks and difficulties that are frequently
encountered by companies transitioning to a new product line and using a new
business strategy. If we are unable to successfully implement our new business
strategy and overcome these challenges, risks and difficulties, our operating
results will suffer.

WE HAVE A HISTORY OF LOSSES AND EXPECT TO INCUR LOSSES IN THE FUTURE.

    We incurred net losses of $9.3 million in 1997, $8.3 million in 1998 and
$10.5 million in 1999. We expect to continue to incur losses in the foreseeable
future. We expect those losses to increase significantly from current levels as
we continue to develop our products and services. We believe that our business
depends on our ability to significantly increase revenue. If our revenues fail
to grow at anticipated rates or our operating expenses increase without a
commensurate increase in our revenues, or we fail to adjust operating expense
levels appropriately, we may not be able to achieve and maintain profitability,
which would increase the possibility that the value of your investment will
decline.

THE MARKET FOR OUR RECENTLY DEVELOPED WEB-BASED SOLUTIONS IS NEWLY EMERGING AND
CLIENT DEMAND MAY NOT EVOLVE AND DEPENDS IN LARGE PART UPON THE GROWTH OF THE
INTERNET, WHICH MAY NOT GROW AS FAST OR AS EFFECTIVELY AS WE ANTICIPATE.

    The market for our recently developed web-based, B2B solutions is newly
emerging and we cannot be certain that this market will continue to develop and
grow or that companies will choose to use our solutions rather than attempt to
develop alternative platforms and applications internally or through other
sources. To improve our operating results, we must keep pace with the evolving
industry standards that are characterized by rapid technological advances and
changing customer needs. If we fail in the development and marketing of either
enhancements to our current

                                       6
<PAGE>
TradeSphere and TradePrism.com solutions or new solutions that respond to
technological advances in a timely and cost-effective basis, our ability to
generate revenues may be reduced. In addition, the anticipated growth of the
global trade market may depend on the growth of the Internet. Increased use of
the Internet largely depends upon available Internet security, bandwidth and
reliability. If use of the Internet by businesses does not increase as fast and
as effectively as we currently anticipate, the market for our web-based global
solutions may not grow as we expect and our business may be harmed.

ANY RESTRICTION ON OUR ABILITY TO COST EFFECTIVELY ACCESS A FOREIGN COUNTRY'S
RULES AND REGULATIONS THAT ARE INCORPORATED INTO OUR GLOBAL TRADE CONTENT,
GLOBAL ECONTENT, OR ANY FAILURE TO TIMELY UPDATE GLOBAL ECONTENT TO INCLUDE
CHANGES IN SUCH RULES AND REGULATIONS, MAY HARM OUR BUSINESS.

    The success of our global trade management solutions for our clients depends
on our ability to access the complex rules and regulations published by foreign
governments governing a particular country's import and export of goods. The
foundation of our global trade solution, Global eContent, is subject to rapid
change at the initiative of foreign governments, based on factors beyond our
control. Any changes in a country's rules and regulations relating to global
trade that we are unable to include in our Global eContent library may result in
dissatisfied clients and possible litigation. In addition, to the extent a
foreign government restricts our access to its rules and regulations, charges a
fee for such access or grants proprietary rights to such information to one or
more of our competitors, our business may be harmed and our revenues could
decrease.

FLUCTUATIONS IN OUR OPERATING RESULTS, PARTICULARLY COMPARED TO THE EXPECTATIONS
OF MARKET ANALYSTS AND INVESTORS, MAY LEAD TO A REDUCED PRICE OF OUR COMMON
STOCK.

    Our operating results have varied in the past, and we expect that they will
continue to vary in the future as a result of a number of factors, many of which
are beyond our control. These factors include:

    - Demand for our products and services;

    - Increases in our operating expenses;

    - Competition in our industry;

    - Variability in the mix of our subscription and transaction revenues and
      our consulting revenues;

    - Timing of new solution introductions and enhancements to our TradeSphere
      and TradePrism.com solutions;

    - Continued business from our existing clients;

    - The loss of any key employees and timing of our new hires; and

    - Significant downturns in the U.S. and international economies.

    Due to the foregoing factors, our annual or quarterly results of operations
may not meet the expectations of securities analysts and investors, which could
cause the price of our common stock to decline.

    In addition, seasonal trends with respect to our revenue derived from our
consulting services may harm our quarterly operating results. For example, in
the fourth quarter of our 1999 fiscal year our revenues were lower than our
revenues in each of the prior three quarters. We believe that the primary cause
of this fluctuation is the decrease in the amount of services that we provided
to our

                                       7
<PAGE>
clients in the fourth quarter due to year-end client holiday schedules and
client postponements of new service engagements in order to concentrate on Year
2000 readiness.

WE ARE GROWING RAPIDLY AND EFFECTIVELY MANAGING OUR GROWTH MAY BE DIFFICULT.

    We have significantly increased our employee base to meet increasing demand
for our client solutions. The number of our employees has increased from 104 as
of December 31, 1998 to 230 as of March 31, 2000. As we expand our operations,
we expect to continue to increase the size of our employee base. Our management
and operations have been strained by this growth and will continue to be
strained by our anticipated growth. To compete effectively and to manage future
growth, we must continue to improve our financial and management controls,
reporting systems and procedures on a timely basis. We must also expand, train
and manage our employee base. If we are not successful in managing our growth,
our business may be harmed.

SEVERAL KEY EXECUTIVE OFFICERS HAVE RECENTLY JOINED OUR MANAGEMENT TEAM AND THE
INABILITY OF OUR MANAGEMENT TEAM TO SUCCESSFULLY WORK TOGETHER COULD HARM OUR
BUSINESS.

    Some members of our current management team have been in place for only a
relatively short period of time. Our Chief Operating Officer, Senior Vice
President of Worldwide Sales, Senior Vice President of Global Services, Vice
President of Marketing and Vice President of Technology all joined us within the
last nine months. Accordingly, each of these individuals has limited experience
with our company. Our new executive officers may not be able to integrate
themselves into our daily operations and to work effectively as a team, which
could harm our business by impairing our ability to implement our business
strategy.

WE MAY BE UNABLE TO ATTRACT AND RETAIN KEY PERSONNEL, WHICH WOULD ADVERSELY
AFFECT OUR BUSINESS.

    Our future performance will depend largely on the efforts and abilities of
our senior executives, key technical, professional services, sales and marketing
and managerial personnel. Our success will depend on our ability to attract and
retain these key employees in the future. The employment of our key personnel,
including our executives, is at will. The market for such persons is extremely
competitive and we may not find qualified replacements for personnel who leave
us. In the past, we have experienced difficulty in hiring qualified technical,
professional services, sales, marketing and managerial personnel. In addition,
we do not maintain key person life insurance on any of our key personnel, and
have no plans to do so. The loss of, or the inability to attract, any one or
more of our key personnel may harm our business and adversely affect your
investment in our common stock.

IF WE ARE UNABLE TO OBTAIN ADDITIONAL CAPITAL AS NEEDED IN THE FUTURE, OUR
BUSINESS MAY BE ADVERSELY AFFECTED AND THE MARKET PRICE FOR OUR COMMON STOCK
COULD DECLINE.

    We have historically financed our operations primarily through the sale of
our securities. We may need to raise additional debt or equity capital to fund
the expansion of our operations, to enhance our products and services, or to
acquire or invest in complementary products, services, businesses or
technologies. If we raise additional funds through further issuances of equity
or convertible debt or equity securities, our existing stockholders could suffer
significant dilution, and any new equity securities we issue could have rights,
preferences and privileges superior to those of holders of our common stock,
including shares of common stock sold in the offering. In addition, we may not
be able to obtain additional financing on terms favorable to us, if at all. If
adequate funds are not available on terms favorable to us, our business may be
adversely affected and the market price for our common stock could decline.

                                       8
<PAGE>
OUR INTERNATIONAL OPERATIONS AND PLANNED EXPANSION EXPOSE US TO BUSINESS RISKS
THAT COULD CAUSE OUR OPERATING RESULTS TO SUFFER.

    We opened an office in the United Kingdom in January 1999, and intend to
expand substantially our international operations and enter new international
markets. This expansion will require significant management attention and
financial resources to successfully translate our software products into various
languages, to develop compliance expertise relating to international regulatory
agencies and to develop direct and indirect international sales and support
channels. We face a number of risks associated with conducting our business
internationally that could negatively impact our operating results, including:

    - language barriers, conflicting international business practices and other
      difficulties relating to the management and administration of a global
      business;

    - longer sales cycles associated with educating foreign clients about the
      benefits of our products and services;

    - currency fluctuations and exchange rates;

    - multiple and possibly overlapping tax structures and the burdens of
      complying with a wide variety of foreign laws;

    - the need to consider characteristics unique to technology systems used
      internationally; and

    - economic or political instability in some international markets.

    We may be unable to establish, maintain or increase international market
demand for our solutions and, if we are unable to do so, international sales may
be limited, and our business may be harmed. We also may not succeed in our
efforts to enter new international markets and expand our international
operations, which may harm our business.

IF OUR EXISTING CLIENTS DO NOT PURCHASE ADDITIONAL COMPONENTS OF OUR SOLUTIONS,
WE MAY NOT ACHIEVE GROWTH IN OUR REVENUES.

    Our clients' initial implementations often include only one or two
components of our global trade management solutions. Clients may subsequently
add other components of our solutions and may eventually purchase and use the
full suite of our TradeSphere offerings. If our clients are not satisfied with
their initial implementations and they decline to purchase additional components
of our solutions, our business would be adversely impacted.

WE MAY BE UNABLE TO SELL OUR WEB-BASED SOLUTIONS IF OUR TARGET CLIENTS DO NOT
ACCEPT OUR SUBSCRIPTION AND TRANSACTION-BASED PRICING MODEL.

    Our new subscription and transaction-based pricing model for our web-based
solutions is untested and will require our clients to make recurring
subscription and transaction fee payments instead of a one-time capital
investment followed by the payment of fees for maintenance and support. Our
current and future clients may not accept our pricing model. If we are unable to
receive acceptance by our current and future clients of this pricing model, our
sales could suffer.

OUR LENGTHY AND VARIABLE SALES CYCLE MAKES IT DIFFICULT FOR US TO PREDICT WHEN
OR IF SALES WILL OCCUR AND THEREFORE WE MAY EXPERIENCE AN UNPLANNED SHORTFALL IN
REVENUES.

    Our products have a lengthy and unpredictable sales cycle that contributes
to the uncertainty of our operating results. Clients typically view the purchase
of our solutions as a significant and strategic decision. As a result, clients
generally evaluate our solutions and determine their impact on existing
infrastructure over a lengthy period of time. Our sales cycle has historically
ranged from

                                       9
<PAGE>
approximately one to nine months depending on a particular client's need to
rapidly implement a solution and whether the client is new or is extending an
existing implementation. The license of our software products may be subject to
delays if the customer has lengthy internal budgeting, approval and evaluation
processes. We may incur significant selling and marketing expenses during a
client's evaluation period, including the costs of developing a full proposal
and completing a rapid proof of concept or custom demonstration, before the
client engages us. Larger clients may purchase our solutions as a part of
multiple simultaneous purchasing decisions, which may result in additional
unplanned administrative processing and other delays. If revenues forecasted
from a specific client for a particular quarter are not realized or are delayed
to another quarter, we may experience an unplanned shortfall in revenues, which
could adversely affect our operating results.

ANY LOSS OF OUR STRATEGIC RELATIONSHIPS OR FAILURE TO DEVELOP NEW RELATIONSHIPS
WOULD HARM OUR BUSINESS.

    We have established strategic relationships with a number of third parties
including Arzoon.com, i2 Technologies, JD Edwards, Oracle, RightFreight.com, SAP
and SupplierMarket.com. These relationships are important to the worldwide
implementation, integration, development and promotion of our solutions. We
expect these relationships to provide us with marketing and sales opportunities.
If we are unable to maintain successfully our existing relationships or develop
new relationships, our business may be harmed.

ANY LOSS OF OUR LICENSED THIRD-PARTY TECHNOLOGY MAY RESULT IN INCREASED COSTS OF
OR DELAYS IN PROVIDING OUR SOLUTIONS, WHICH WOULD HARM OUR OPERATING RESULTS.

    We license technology from several companies on a non-exclusive basis that
is integrated into our TradeSphere product suite, including database technology
from Oracle and Microsoft, development tools and facilities from IBM (WebSphere
and MQ Series) and Forte, which was acquired by Sun Microsystems. We anticipate
that we will continue to license technology from these and other third parties
in the future. This software may not continue to be available on commercially
reasonable terms, or at all. Some of the software we license from third parties
would be difficult and time-consuming to replace. The loss of any of these
technology licenses could result in delays in the licensing of our TradeSphere
products until equivalent technology, if available, is identified, licensed and
integrated. In addition, the effective implementation of our products may depend
upon the successful operation of third-party licensed products in conjunction
with our products, and therefore any undetected errors in these licensed
products may prevent the implementation or impair the functionality of our
products, delay new product introductions and injure our reputation.

WE MAY FACE PRODUCT LIABILITY CLAIMS, WHICH MAY HARM OUR FINANCIAL CONDITION.

    The foundation of our TradeSphere solutions, Global eContent, consists of
the complex and continually changing country-specific rules and regulations
published by foreign governments in connection with the import and export of
goods. The organic and complex nature of Global eContent increases the
likelihood that we may face product liability claims in connection with our
current products and future products. A successful product liability claim
brought against us could harm our financial condition. Even if unsuccessful, any
product liability claim could result in costly litigation and divert
management's attention and resources. Any provisions in our license agreements
designed to limit our exposure to potential product liability claims and any
product liability insurance may not be adequate to protect us from such claims.

                                       10
<PAGE>
THE UNCERTAINTY OF FUTURE GOVERNMENT REGULATION OF THE INTERNET AND GLOBAL TRADE
MAY ADD TO OUR OPERATING COSTS.

    Like many businesses engaging in Internet-related business activities, we
may face unanticipated operating costs because of the current uncertainty
surrounding potential government regulation of the Internet and e-commerce. We
believe that we are not currently subject to direct regulation of online
commerce, other than regulations applicable to businesses generally. However,
the Internet has rapidly emerged as a commerce medium, and governmental agencies
have not yet been able to adapt all existing regulations to the Internet
environment. Laws and regulations may be introduced and court decisions reached
that affect the Internet or other online services, covering issues such as user
pricing, user privacy, freedom of expression, access charges, content and
quality of products and services, advertising, intellectual property rights and
information security. As an Internet company, it is unclear in which
jurisdictions we are actually conducting business. Our failure to qualify to do
business in a jurisdiction that requires us to do so could subject us to fines
or penalties and could result in our inability to enforce contracts in that
jurisdiction. Even if we were able to ascertain correctly in which jurisdictions
we conduct business, many of these jurisdictions have yet to determine the
application of their existing laws to web-based global trade or develop laws
that apply to such trade.

WE MAY BE UNABLE TO ADEQUATELY PROTECT OUR PROPRIETARY RIGHTS, WHICH COULD
RESULT IN THEIR UNAUTHORIZED USE AND HARM OUR BUSINESS.

    Our success depends on our ability to protect our proprietary rights. We
rely primarily on:

    - Copyright, trade secret and trademark laws;

    - Confidentiality agreements with employees and third parties; and

    - Protective contractual provisions such as those contained in license
      agreements with consultants, vendors and clients, although we have not
      signed such agreements in every case.

    Despite our efforts to protect our proprietary rights, unauthorized parties
may copy aspects of our products and obtain and use information we regard as
proprietary. Other parties may breach confidentiality agreements and other
protective contracts. We may not become aware of these breaches or have adequate
remedies available. We may need to litigate claims against third parties who
infringe our intellectual property rights, which could be costly.

    We have not secured registration of all our marks in the United States and
have not pursued registration of our intellectual property in any foreign
country. The laws of some foreign countries do not protect our proprietary
rights to the same extent as do the laws of the United States. Effective
copyright, trademark and trade secret protection may not be available in other
jurisdictions. If we cannot adequately protect our proprietary rights, our
business may be harmed.

OUR PATENT STRATEGY IS IN DEVELOPMENT CURRENTLY AND ANY INADEQUACY IN THE
PROTECTION OF OUR TECHNOLOGY COULD HURT OUR BUSINESS.

    We may also rely on patents to protect our proprietary rights in the future.
Any patent strategy we attempt to implement may not be successful and could harm
our business by disclosing unpatentable trade secrets. The laws that apply to
the types of patents we may seek are evolving and are subject to change. We
presently have filed provisional patent applications in the United States. These
applications may not result in patents or may take longer than we expect to
result in patents. We may also decide to not file patent applications in all the
countries in which we operate or intend to operate. Our decision to do so may
inhibit our ability to protect our proprietary rights in those countries. Even
if we are issued patents, we cannot assure you that they will provide us any

                                       11
<PAGE>
meaningful protection or competitive advantage. If we try to enforce our
patents, third parties may challenge our patents in court or before the United
States Patent and Trademark Office. An unfavorable outcome in any such
proceeding could require us to cease using the technology or to license rights
from prevailing third parties. There is no guarantee that any prevailing party
would offer us a license or that we could acquire any license made available to
us on commercially acceptable terms, which may harm our business.

COMPETITION IN OUR MARKET COULD MAKE IT DIFFICULT TO ATTRACT CUSTOMERS, CAUSE US
TO REDUCE PRICES, RESULTING IN REDUCED GROSS MARGINS, OR CAUSE US TO FAIL TO
GAIN MARKET SHARE OR EXPERIENCE A LOSS OF MARKET SHARE, ANY OF WHICH WOULD HARM
OUR BUSINESS.

    The market for our products and services is competitive, dynamic and subject
to frequent technological changes. The intensity of competition and the pace of
change are expected to increase in the future. Our solutions face competition
from a number of competitors offering products and services that vary in
functionality including:

    - Content aggregators such as Dun & Bradstreet and TradeCompass;

    - International trade logistics providers such as Capstan, Nextlink,
      Rockport and Syntra;

    - Trade consultants such as management consulting firms, law firms and
      boutique consulting firms; and

    - Outsourcing service providers, such as third party logistics providers,
      fourth party logistics providers and carriers.

    We expect additional competition from other established and emerging
companies as the market for global trade solutions evolves. Increased
competition could result in price reductions, reduced gross margins, loss of
market share or failure to gain market share, any of which would seriously harm
our business. We may not be able to compete successfully against current and
future competitors, which may lower the value of your investment in our common
stock.

OUR PRODUCTS ARE COMPLEX AND MAY CONTAIN DEFECTS OR ERRORS.

    Some of the software products may contain undetected errors or defects,
especially when first introduced or when new versions are released. Our new
products or releases may not be free from errors after commercial shipment. Any
errors discovered after commercial release could result in loss of revenues or
delay in market acceptance of our products, diversion of development resources,
damage to our reputation, lawsuits or increased service costs, all of which
could harm our business.

ANY FUTURE ACQUISITIONS MAY BE DIFFICULT AND DISRUPTIVE, AND WE MAY NOT REALIZE
THE EXPECTED BENEFITS FROM THOSE ACQUISITIONS.

    We may expand our operations or market presence by acquiring or investing in
companies, assets or technologies that complement our business and offer
opportunities for growth. These transactions involve many risks and challenges
that we might not successfully overcome, including:

    - Difficulties in assimilating technologies, products, personnel and
      operations;

    - Disruption of our ongoing business and diversion of management's attention
      from other business concerns;

    - Risks of entering markets in which we have no or limited prior experience;

    - Issuances of equity securities that may dilute your ownership interest in
      our common stock;

                                       12
<PAGE>
    - Cash payments to or the assumption of debt or other liabilities of the
      companies we acquire; and

    - Large write-offs and amortization expenses related to goodwill and other
      intangible assets.

    Our inability to address these risks could negatively impact our operating
results. Moreover, any future acquisitions or investments, even if successfully
completed, may not generate any additional revenue or provide any benefit to our
business.

POTENTIAL YEAR 2000 PROBLEMS WITH OUR PRODUCTS OR INTERNAL SYSTEMS MAY INVOLVE
SIGNIFICANT TIME AND EXPENSE AND MAY HARM OUR BUSINESS.

    Although no material year 2000 problems with our solutions have been brought
to our attention to date, year 2000 problems emerging in the future could
subject us to liability claims and disrupt our clients' purchasing patterns,
either of which could harm our business. Our solutions rely on computer systems
and software products which operate in complex network environments. Our
solutions, directly or indirectly, interact with a number of other hardware and
software systems that we cannot adequately evaluate for year 2000 compliance. We
may face claims based on year 2000 problems in other companies' products, or
issues arising from the integration of multiple products within an overall
system. We may in the future be required to defend our applications, services
and product offerings in such proceedings, or to negotiate resolutions of claims
based on year 2000 issues. Defending and resolving any year 2000 related
problems or disputes could be expensive to us and reduce our operating results.

                         RISKS RELATED TO THIS OFFERING

OUR STOCK PRICE MAY BE VOLATILE AND MAY SUBJECT US TO SECURITIES LITIGATION,
WHICH IS EXPENSIVE AND COULD DIVERT OUR RESOURCES.

    The market price for our shares of common stock is likely to be volatile
and, if you decide to purchase our shares, you may be unable to resell your
shares at or above the initial public offering price due to a number of factors,
including:

    - Actual or anticipated variations in our operating results;

    - Changes in earnings estimates by analysts;

    - Announcements of technological innovations or new products by our
      competitors; and

    - General economic conditions in global trade and e-commerce industries.

    In addition, the stock market has experienced extreme price and volume
fluctuations that affected the market price of many companies in our industry
and that have been unrelated to these companies' operating performances. These
broad market fluctuations could reduce the market price of our common stock and,
in some instances, we may become subject to securities litigation. If we become
involved in this type of litigation, regardless of the outcome, we could incur
substantial legal costs and our management's attention could be diverted,
causing our business to suffer.

OUR OFFICERS, DIRECTORS AND AFFILIATES WILL BE ABLE TO CONTROL MATTERS REQUIRING
STOCKHOLDER APPROVAL AND MAY HAVE INTERESTS THAT DIFFER FROM YOURS.

    Following the closing of this offering, our officers, directors and
affiliated entities together will beneficially own approximately   % of the
outstanding shares of our common stock,   % if the

                                       13
<PAGE>
underwriters' over-allotment option is exercised in full. Accordingly, these
stockholders will be able to control all matters requiring stockholder approval
and, thereby, our management and affairs. In addition, this concentration of
ownership may delay, deter or prevent acts that would result in a change of
control, which in turn could reduce the market price of our common stock. These
stockholders may have interests that differ from your interests and their
decisions may negatively impact our business.

OUR MANAGEMENT HAS BROAD DISCRETION OVER HOW TO USE THE PROCEEDS OF THIS
OFFERING; WE MAY NOT USE THE PROCEEDS IN WAYS THAT HELP OUR BUSINESS SUCCEED.

    We estimate that our net proceeds from this offering will be $      million,
at an assumed initial public offering price of $  per share and after deducting
the estimated underwriting discount and offering expenses. Our primary purposes
in making this offering are to increase our working capital, create a public
market for our common stock, facilitate our future access to the public capital
markets and increase our visibility in the marketplace. We have no specific
plans for the net proceeds of this offering other than working capital and
general corporate purposes, although we may use a portion of the net proceeds to
acquire or invest in additional businesses, products and technologies.
Accordingly, our management will have broad discretion as to how to apply the
net proceeds of this offering. If we fail to use these proceeds effectively, our
business may not grow and our revenues may decline.

OTHER COMPANIES MAY HAVE DIFFICULTY ACQUIRING US, EVEN IF DOING SO WOULD BENEFIT
OUR STOCKHOLDERS, DUE TO PROVISIONS OF OUR CORPORATE CHARTER AND BYLAWS AND
DELAWARE LAW.

    Provisions in our certificate of incorporation, in our bylaws and under
Delaware law could make it more difficult for other companies to acquire us,
even if doing so would benefit our stockholders. Our certificate of
incorporation and bylaws contain the following provisions, among others, which
may inhibit an acquisition of our company by a third party:

    - a staggered board of directors, where stockholders elect only a minority
      of the board each year;

    - advance notification procedures for matters to be brought before
      stockholder meetings;

    - a limitation on who may call stockholder meetings; and

    - a prohibition on stockholder action by written consent.

    We are also subject to provisions of Delaware law that prohibit us from
engaging in any business combination with any "interested stockholder," meaning
generally a stockholder who beneficially owns more than 15% of our stock, for a
period of three years from the date this person became an interested
stockholder, unless various conditions are met, such as approval of the
transaction by our board. This could have the effect of delaying or preventing a
change in control. For a more complete discussion of these provisions of
Delaware law, please see "Description of Capital Stock--Delaware Anti-Takeover
Law and Provisions in Our Charter and Bylaws."

                           FORWARD-LOOKING STATEMENTS

    This prospectus contains forward-looking statements that address, among
other things, market acceptance of our solutions, expansion into new targeted
industries, product development, sales and marketing strategies, development and
maintenance of strategic alliances, technological advancement, global expansion,

this prospectus entitled "Prospectus Summary," "Risk Factors," "Use of
Proceeds," "Management's Discussion and Analysis of Financial Condition and
Results of Operations," "Our Business" and in this prospectus generally. In some
cases, you can identify forward-looking statements by terminology such as "may,"

"predicts," "potential," "continue" or the negative of such terms or other
comparable terminology. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of various factors,
including all the risks discussed in "Risk Factors" and elsewhere in this

                                USE OF PROCEEDS

    We expect to receive approximately $           million in net proceeds from
the sale of the       shares of common stock in this offering, assuming that the
initial public offering price is $               per share and after deducting
estimated underwriting discounts and commissions and estimated offering expenses
payable by us. We expect to receive approximately $               million if the
underwriters' over-allotment option is exercised in full.

    We intend to use the net proceeds of this offering for general corporate
purposes, principally working capital for increased domestic and international
sales and marketing expenditures, product development expenditures, expenditures
related to the expansion of our consulting services organization and capital
expenditures made in the ordinary course of business. We may also use a portion
of the net proceeds to acquire or invest in additional businesses, products and
technologies that we believe will complement our current or future business.
However, we have no specific plans, agreements or commitments, oral or written,
to do so. We are not currently engaged in any negotiations for any acquisition
or strategic investment. The amounts that we actually expend for working capital
purposes will vary significantly depending on a number of factors, including
future revenue growth, if any, the amount of cash we generate from operations
and the progress of our product development efforts. As a result, we will retain
broad discretion in the allocation of the net proceeds of this offering. Pending
the uses described above, we will invest the net proceeds in short-term,
interest-bearing, investment-grade securities.

                                DIVIDEND POLICY

    We have never paid cash dividends on our common stock. We currently intend
to retain any future earnings to fund the development and growth of our
business, and we do not anticipate paying any cash dividends in the future.

                                    DILUTION

    As of December 31, 1999, our net tangible book value on a pro forma basis
giving effect to the conversion of our preferred stock into common stock upon
consummation of this offering was approximately $               million or
$           per share of common stock. "Net tangible book value" per share
represents the amount of our total tangible assets reduced by the amount of our
total liabilities, divided by the number of shares of common stock outstanding.
As of December 31,1999, our net tangible book value, on a pro forma basis as
adjusted for the sale of       shares of our common stock, based on an assumed
initial public offering price of $           per share and after deducting the
underwriting discounts and commissions and other estimated offering expenses,
would have been approximately $           per share. This represents an
immediate increase of $               per share to existing stockholders and an
immediate dilution of $               per share to new investors. The following
table illustrates this per share dilution:

public offering price of $               per share.

      warrants to purchase our common stock.

    To the extent all of these options and warrants had been exercised as of

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    THE FOLLOWING DISCUSSION AND ANALYSIS OF THE FINANCIAL CONDITION AND RESULTS
OF OPERATIONS OF VASTERA, INC. SHOULD BE READ IN CONJUNCTION WITH "SELECTED
CONSOLIDATED FINANCIAL DATA" AND VASTERA'S CONSOLIDATED FINANCIAL STATEMENTS AND
RELATED NOTES APPEARING ELSEWHERE IN THIS PROSPECTUS WHICH ARE DEEMED TO BE
INCORPORATED INTO THIS SECTION. OUR ACTUAL RESULTS COULD DIFFER MATERIALLY FROM
THOSE ANTICIPATED IN SUCH FORWARD-LOOKING STATEMENTS DUE TO VARIOUS FACTORS,
INCLUDING, BUT NOT LIMITED TO, THOSE SET FORTH UNDER "RISK FACTORS" AND
ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

    We are a leading provider of solutions for global trade management. Our
offerings include an extensive online library of global trade content, B2B
solutions, management consulting and solution services. In 1992, we introduced
EMS-2000, a U.S.-centric, DOS based export management solution. In 1994, we
introduced EMS-2000 Version 4, a multi-country, two-tier, Windows-based export
management solution. In 1997, we introduced Global Passport, a multi-country,
three-tier, client-server based, import/export management solution. In 1999, we
introduced TradeSphere, a multi-country, multi-module suite of web-based global
trade management solutions. In 2000, we introduced TradePrism.com, a trade
portal that provides a web-based delivery mechanism for our global trade
management capabilities. Since our inception, we have continued to develop a
comprehensive suite of solutions with features, functionality and services that
allow companies to manage the complexities of global trade.

    In January 1999, we acquired Deltac Ltd., a provider of trade content and
management consulting expertise for the United Kingdom (UK) and European Union
(EU). In addition, in June 1999, we acquired Quantum Consulting Associates, Inc.
of Denver, Colorado to enhance our trade process consulting services and trade
expertise. We provide our products and services from our offices in the United
States and United Kingdom to over 200 clients. Our clients typically acquire a
limited number of server and user subscriptions or licenses to implement in a
division or department. As they expand implementation of our products globally
and to their customers, suppliers, and business partners, additional
subscriptions or licenses are acquired. We currently market our products and
services on a global basis through our direct sales force and other channels,
such as strategic alliances and partners. We expect revenues from our
international operations to increase as we continue to expand our international
sales and services organizations.

    We have incurred significant losses in order to grow our business and as of
December 31, 1999 had an accumulated deficit of approximately $53.7 million. We
believe our future success depends on increasing our client base, further
developing additional global trade data and content and introducing new products
and services to the marketplace. Prior to 1999, we have derived substantially
all of our revenues from sales of our client-server based solutions EMS-2000 and
Global Passport. As we continue to focus our development and marketing efforts
on TradeSphere and TradePrism.com, we expect to derive an increasingly higher
percentage of revenues from these web-based B2B solutions. Because these
solutions are new in the marketplace, we expect our revenues to be increasingly
uncertain and subject to fluctuations. In addition, to complete the development
of our web-based solutions, we intend to continue to invest heavily in research
and development, sales, marketing and management consulting services; therefore,
we expect to continue to incur substantial operating losses in the foreseeable
future.

SOURCE OF REVENUES AND REVENUE RECOGNITION POLICY

    Our revenues consist of subscription/transaction revenues and service
revenues. Revenues classified as subscription/transaction consist of
subscriptions, transactions and sales of perpetual

                                       20
<PAGE>
software licenses, maintenance and solution services. Revenues from software
licenses, maintenance contracts, and subscription arrangements are recognized
ratably over the estimated economic life of the product (three years) or, if
stated, the contract term. Certain agreements provide for transaction fees based
on usage of our products and revenues are recognized when transactions occur.
Maintenance contracts include the right to unspecified enhancements on a
when-and-if available basis, ongoing support, and content update services. In
general, all of our active clients renew these maintenance contracts to obtain
access to these regular content updates, which are critical to the continued
maintenance of such clients' systems. Historically, we have not experienced
significant returns or exchanges of our products. As we continue to focus our
marketing efforts on our web-based, B2B solutions, we expect
subscription/transaction revenues to increase as a percentage of total revenues.

    Service revenues are derived from implementation, management consulting and
training services. Our service revenues are provided on a time-and-materials or
on a fixed-price basis and are recognized as the services are performed or on a
percentage-of-completion basis. Our service revenues have increased due to the
growth in our customer base, expansion of our implementation organization and
expansion of our management consulting organization. In the future we expect
service revenues to decrease as a percentage of total revenues.

    Our product sales cycle is typically one to nine months. Furthermore, we
have experienced, and expect to continue to experience, significant variation in
the size of individual sales. As a result of this and other factors, our results
have varied significantly in the past and are likely to be subject to
significant fluctuations in the future. Since subscription/transaction revenues
are recognized ratably, typically over three years, and the timing of service
revenues is dependent on the scope of the engagement, we believe that
period-to-period comparisons of the results of operations are not necessarily
indicative of the results we expect for any future period.

DEFERRED REVENUES

    Deferred revenues include amounts billed to clients for which revenues have
not been recognized and generally result from billed, but deferred
subscription/transaction revenues and deferred services not yet rendered.
Deferred revenues will be recognized on a monthly basis over the remaining
economic life of the product or recognized as revenues when the service is
performed.

COST OF REVENUES

    Cost of revenues includes the cost of our subscription/transaction revenues
and the cost of our service revenues. Cost of subscription/transaction revenues
includes royalties due to third parties for technology products integrated into
our software products. It also includes the cost of salaries and related
expenses for our client support function. The cost of subscription/transaction
revenues also includes the costs related to solution services offerings. As we
further develop our solution services, we expect our cost of revenues to
increase due to the increase in our providing hosting and outsourcing services
to our clients. We expect the cost of subscription/transaction revenues to
increase as we expand our solution services offerings and integrate other
technology products into our offerings.

    Cost of service revenues includes the cost of salaries and related expenses
for implementation, management consulting, and training services provided to
customers, as well as, the cost of third parties contracted to provide either
application consulting or implementation services to our customers. Because our
cost of service revenues is greater than the cost of subscription/transaction
revenues, total cost of revenues may fluctuate based on the mix of products and
services sold.

DEPRECIATION AND AMORTIZATION

    Depreciation and amortization expenses consist of the depreciation expense
associated with our computer equipment; purchased software; furniture, fixtures
and equipment; and leasehold improvements and the amortization of goodwill
acquired through business combinations. Depreciation is computed using the
straight-line method over the estimated useful lives of the assets, generally
three to five years. Assets acquired under capital leases and leasehold
improvements are depreciated using the straight-line method over the shorter of
the estimated useful lives of the assets or the terms of the leases.

    In January 1999, we acquired Deltac Ltd., a provider of trade content and
management consulting expertise for the UK and the EU. In addition, in
June 1999, we acquired Quantum Consulting Associates, Inc. of Denver, Colorado
to enhance our trade process consulting services and trade expertise. We
recorded these acquisitions under the purchase method of accounting. The excess
of the consideration over the fair value of the acquired assets and liabilities,
approximately $2.4 million, was accounted for as goodwill. Goodwill is being
amortized on a straight-line basis over five years and resulted in charges to
operations of approximately $313,000 for year ended December 31, 1999.
Amortization for future periods will be approximately $480,000 for the years
ending December 31, 2000, 2001, 2002, 2003 and approximately $167,000 in 2004.

STOCK OPTION COMPENSATION

    We recorded deferred compensation of approximately $6.4 million in the last
three months of 1999. During the first three months of 2000, the Company expects
to record deferred compensation of approximately $11.8 million. These amounts
represents the difference between the exercise price and the fair value for
accounting purposes of the underlying common stock at the date of grant. This
amount is included as a component of stockholders' equity and is being amortized
on an accelerated basis over the applicable vesting period.

    For the year ended December 31, 1999, we amortized approximately $378,000 of
deferred compensation. We expect to amortize deferred compensation of
approximately $8.2 million, $5.4 million, $2.8 million, $1.3 million and
$133,000 for the years ended December 31, 2000, 2001, 2002, 2003 and 2004. The
amount of stock option compensation expense to be recorded in future periods
could decrease if options are forfeited for which accrued but unvested
compensation has been recorded.

BENEFICIAL CONVERSION

    On February 4, 2000, pursuant to a stock purchase agreement with new and
existing investors, we issued approximately 1,570,000 shares of Series E
convertible preferred stock for approximately $17.0 million. The Company expects
to record a beneficial conversion feature of approximately $8.1 million in the
first quarter of 2000 to reflect the difference between the underlying
convertible price per share of common stock and the estimated fair market value
of the common stock on the date of issuance.

RESEARCH AND DEVELOPMENT

    In accordance with Statement of Financial Accounting Standards No. 86,
"Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise
Marketed", we have evaluated the establishment of technological feasibility of
our products during the development phase. The time period during which costs
could be capitalized from the point of reaching technological feasibility until
the time of general product release is very short and, consequently, the amounts
that could be capitalized are not material to our financial position or results
of operations.

</TABLE>

COMPARISON OF YEAR ENDED DECEMBER 31, 1998 TO YEAR ENDED DECEMBER 31, 1999

REVENUES

    TOTAL REVENUES.  Total revenues increased 116% from approximately
$8.9 million for the year ended December 31, 1998 to approximately
$19.1 million for the year ended December 31, 1999.

    SUBSCRIPTION/TRANSACTION REVENUES.  Subscription/transaction revenues
increased 78% from approximately $4.1 million for the year ended December 31,
1998 to approximately $7.3 million for the year ended December 31, 1999. We
attribute this increase primarily to growth in our client base resulting from
increased market acceptance of our product offerings and our increased sales and
marketing efforts. As we continue to focus our development and marketing efforts
on our web-based, B2B solutions, we expect that subscription/transaction
revenues will increase as a percentage of total revenues.

    SERVICE REVENUES.  Service revenues increased 148% from approximately
$4.8 million for the year ended December 31, 1998 to approximately
$11.9 million for the year ended December 31, 1999. This increase resulted
primarily from increases in our customer base and increases in our average
billing rates. The increase in service revenues as a percentage of total
revenues was also

                                       23
<PAGE>
attributable to the acquisitions of Deltac, Ltd. and Quantum Consulting
Associates. We expect the proportion of service revenues to total revenues to
decrease.

COST OF REVENUES

    COST OF SUBSCRIPTION/TRANSACTION REVENUES.  The cost of
subscription/transaction revenues decreased 2% from approximately $708,000 for
the year ended December 31, 1998 to approximately $692,000 for the year ended
December 31, 1999. While we had an increase in our customer support costs, it
was more than offset by our ability to negotiate more favorable royalty rates
for technology products integrated into our software products. The cost of
subscription/ transaction revenues, as a percentage of subscription/transaction
revenues, was 17% for the year ended December 31, 1998 and 10% for the year
ended December 31, 1999. We expect the cost of subscription/transaction revenues
to increase as a percentage of subscription/transaction revenues as we expand
our solution services offerings and integrate other technology products into our
offerings.

    COST OF SERVICE REVENUES.  The cost of service revenues increased 140% from
approximately $4.2 million for the year ended December 31, 1998 to approximately
$10.1 million for the year ended December 31, 1999. This increase resulted
primarily from the hiring and training of consulting and training personnel to
support our increased customer base. The cost of service revenues, as a
percentage of service revenues was 88% for the year ended December 31, 1998 and
85% for the year ended December 31, 1999. This decrease reflects productivity
improvements in our implementation and training organizations in 1999. However,
this decrease was offset by our hiring and investment in our management
consulting organization. We expect the cost of service revenues to decrease as a
percentage of service revenues as we continue to make productivity improvements
in both our management consulting as well as our implementation and training
organizations.

GROSS PROFIT

    Gross profit increased 112% from approximately $4.0 million for the year
ended December 31, 1998 to approximately $8.4 million for the year ended
December 31, 1999. This increase is attributable to the growth in our customer
base, which increased subscription/transaction revenues and service revenues.
Gross margin decreased from 45% for the year ended December 31, 1998 to 43% in
the year ended December 31, 1999. This decrease was due primarily to the
investments made in our management consulting organization. We expect gross
margin to increase as we are able to make productivity improvements in our
management consulting organization.

OPERATING EXPENSES

    SALES AND MARKETING.  Sales and marketing expenses consist primarily of
salaries, commissions and bonuses earned by sales and marketing personnel, sales
training events, public relations, advertising, trade shows, and travel expenses
related to both promotional events and direct sales efforts. Sales and marketing
expenses increased 56% from approximately $4.6 million for the year ended
December 31, 1998 to approximately $7.1 million for the year ended December 31,
1999. This increase resulted primarily from our increased investment in sales
and marketing infrastructure, both domestically and internationally, in the
anticipation of future market growth. The investments included significant
personnel related expenses, recruiting fees, travel expenses, and related
facility and equipment costs. In addition, we increased marketing activities,
including trade shows, public relations, direct mail campaigns and other
promotional activities. Sales and marketing expenses represented 52% of our
total revenues for the year ended December 31, 1998 and 38% for the year ended
December 31, 1999. This decrease reflects the higher revenue base, as well as
improvements achieved in productivity of our sales organization.

                                       24
<PAGE>
We believe that we will need to significantly increase our sales and marketing
expenses to expand our market position. As a result, we anticipate that sales
and marketing expenses will continue to increase in absolute dollar amounts in
future years but decrease as a percentage of total revenues.

    RESEARCH AND DEVELOPMENT.  Research and development expenses consist
primarily of salaries, benefits, and equipment for software developers, quality
assurance personnel, program managers, and technical writers. Research and
development expenses increased 45% from approximately $4.3 million for the year
ended December 31, 1998 to approximately $6.2 million for the year ended
December 31, 1999. This increase resulted from an increase in the number of
software developers and quality assurance personnel needed to support our
product development and testing activities. Research and development expenses
represented 48% of our total revenues for the year ended December 31, 1998 and
32% for the year ended December 31, 1999. However, we believe that we must
continue to invest in research and development in order to develop new products
and services. As a result, we anticipate that research and development expenses
will continue to increase in absolute dollar amounts in future years but
decrease as a percentage of total revenues.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of salaries, benefits and related costs for executive, finance,
administrative and information services personnel. These expenses also include
fees for legal, audit and accounting, and other professional services. General
and administrative expenses increased 44% from approximately $2.6 million for
the year ended December 31, 1998 to approximately $3.7 million for the year
ended December 31, 1999. This increase resulted primarily from the addition of
executive, finance, and administrative personnel to support the growth of our
business. General and administrative expenses represented 29% of our total
revenues for the year ended December 31, 1998 and 19% for the year ended
December 31, 1999. The decrease as a percentage of total revenues reflected
efficiencies gained throughout our administrative processes as we have grown as
a company. We believe our general and administrative expenses will continue to
increase in absolute dollar amounts as we expand our administrative staff,
domestically and internationally, and incur expenses associated with becoming a
public company. We expect these expenses to include annual and other public
reporting costs, directors' and officers' liability insurance, investor
relations programs and additional legal, accounting, and consulting fees.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
increased 155% from approximately $600,000 for the year ended December 31, 1998
to approximately $1.6 million for the year ended December 31, 1999. This
increase resulted primarily from purchases of fixed assets to build the
infrastructure needed to support the growth of our business and the amortization
of goodwill from the acquisition of Deltac Ltd. in February 1999 and Quantum
Consulting Associates, Inc. in June 1999. This amortization was zero for the
year ended December 31, 1998 and approximately $313,000 for the year ended
December 31, 1999. Depreciation and amortization expenses represented 7% of our
total revenues for the year ended December 31, 1998 and 8% for the year ended
December 31, 1999.

    STOCK OPTION COMPENSATION.  Stock option compensation expense increased from
zero for the year ended December 31, 1998 to approximately $378,000 for the year
ended December 31, 1999. Deferred compensation of approximately $6.4 million at
December 31, 1999 will be amortized on an accelerated basis over the applicable
vesting period.

    OTHER INCOME (EXPENSES), NET.  Other income (expenses), net fluctuates based
on the amount of cash balances available for investment, borrowings under our
line of credit, interest expense related to our term loans and realized gains
and losses on investments. Other income (expenses), net increased from
approximately ($157,000) for the year ended December 31, 1998 to

                                       25
<PAGE>
$181,000 for the year ended December 31, 1999. This increase reflects the
investment income earned on the proceeds of our private placement during 1998.

    INCOME TAXES.  No provision for income taxes has been recorded for either
the year ended December 31, 1998 or the year ended December 31, 1999 due to
accumulated net operating losses. We have recorded a valuation allowance for the
full amount of our net deferred tax assets as a result of the uncertainty
surrounding the timing of the realization of these future tax benefits.

    As of December 31, 1999, we had net operating loss carry-forwards for
federal tax purposes of approximately $19.5 million. These federal tax loss
carry-forwards are available to reduce future taxable income and begin to expire
in 2011. Under the provisions of the Internal Revenue Code, certain substantial
changes in our ownership have occurred, and as a result, our future utilization
of these net operating carry-forwards, that we accumulated prior to the change
in ownership, may be subject to a limitation per year. We may generate
additional net operating loss carry-forwards in the future.

COMPARISON OF YEAR ENDED DECEMBER 31, 1997 AND YEAR ENDED DECEMBER 31, 1998

REVENUES

    TOTAL REVENUES.  Total revenues increased 137% from approximately
$3.7 million for the year ended December 31, 1997 to approximately $8.9 million
for the year ended December 31, 1998.

    SUBSCRIPTION/TRANSACTION REVENUES.  Subscriptions/transaction revenues
increased 86% from approximately $2.2 million for the year ended December 31,
1997 to approximately $4.1 million for the year ended December 31, 1998. This
increase is primarily attributed to increased market acceptance of our product
offerings.

    SERVICE REVENUES.  Service revenues increased 209% from approximately
$1.5 million for the year ended December 31, 1997 to approximately $4.8 million
for the year ended December 31, 1998. This increase in service revenues is
primarily attributed to our increased sales of our software applications and
overall growth of our installed base of customers.

COST OF REVENUES

    COST OF SUBSCRIPTION/TRANSACTION REVENUES.  Cost of subscription/transaction
revenues decreased 8% from approximately $766,000 for the year ended
December 31, 1997 to approximately $708,000 for the year ended December 31,
1998. Cost of subscription/transaction revenues as a percentage of
subscription/transaction revenues was 35% for the year ended December 31, 1997
and 17% for the year ended December 31, 1998. This decrease was due to our
ability to negotiate during the year more favorable royalty rates for technology
products integrated into our software products.

    COST OF SERVICE REVENUES.  Cost of service revenues increased 186% from
approximately $1.5 million for the year ended December 31, 1997 to approximately
$4.2 million for the year ended December 31, 1998. This increase resulted from
the hiring and training of professional service personnel to support our growing
customer base. Cost of service revenues as a percentage of service revenues was
95% for the year ended December 31, 1997 and 88% for the year ended
December 31,1998. This decrease primarily reflected increased utilization of
professional service personnel.

GROSS PROFIT

    Gross profit increased 162% from approximately $1.5 million for the year
ended December 31, 1997 to approximately $4.0 million for the year ended
December 31, 1998. This increase is

                                       26
<PAGE>
attributable to the growth in our customer base, which increased
subscription/transaction revenues and service revenues. Gross margin increased
from 41% for the year ended December 31, 1997 to 45% for the year ended
December 31, 1998. This increase was due primarily to the increase in
subscription/transaction revenues and improved productivity in our service
organization.

OPERATING EXPENSES

    SALES AND MARKETING.  Sales and marketing expenses increased 3% from
approximately $4.4 million for the year ended December 31, 1997 to approximately
$4.6 million for the year ended December 31, 1998. The increases in sales and
marketing expenses resulted from our investment in sales and marketing
infrastructure, which primarily included personnel related expenses. Sales and
marketing expenses represented 119% of our total revenues for the year ended
December 31, 1997 and 52% for the year ended December 31, 1998. The decrease in
sales and marketing expenses as a percentage of total revenues resulted
primarily from increased revenues in 1998.

    RESEARCH AND DEVELOPMENT.  Research and development expenses increased 3%
from approximately $4.1 million for the year ended December 31, 1997 to
approximately $4.3 million for the year ended December 31, 1998. The increases
in research and development expenses related primarily to the increase in the
number of software developers and quality assurance personnel needed to support
our product development and testing activities. Research and development costs
represented 110% of our total revenues for the year ended December 31, 1997 and
48% for the year ended December 31, 1998. This decrease is due to the completion
of a product upgrade in June 1997 and from increased revenues in 1998.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
50% from approximately $1.7 million for the year ended December 31, 1997 to
approximately $2.6 million for the year ended December 31, 1998. The increase in
general and administrative expenses resulted primarily from the addition of
executive, finance, and administrative personnel to support the growth of our
business during these periods. General and administrative costs represented 46%
of our total revenues for the year ended December 31, 1997 and 29% for the year
ended December 31, 1998. The decrease as a percentage of total revenues
reflected efficiencies gained throughout our general and administrative
functions.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
increased 50% from approximately $426,000 for the year ended December 31, 1997
to approximately $637,000 for the year ended December 31, 1998. This increase
resulted primarily from purchases of fixed assets to build the infrastructure
needed to support the growth of our business. Depreciation and amortization
expenses represented 11% of our total revenues for the year ended December 31,
1997 and 7% for the year ended December 31, 1998.

    OTHER INCOME (EXPENSES), NET.  Other income (expenses), net decreased from
approximately ($98,000) for the year ended December 31, 1997 to approximately
($157,000) for the year ended December 31, 1998. This decrease resulted from the
interest expense incurred from capital equipment leases entered into during the
last part of 1997 and the early part of 1998.

    INCOME TAXES.  No provision for income taxes has been recorded for either
the year ended December 31, 1997 or the year ended December 31, 1998 due to
accumulated net operating losses. We have recorded a valuation allowance for the
full amount of our net deferred tax assets as a result of the uncertainty
surrounding the timing of the realization of these future tax benefits.

    Our operating results have varied on a quarterly basis and may fluctuate
significantly in the future. In addition the quarterly results of any quarter do
not indicate results to be expected for a full fiscal year.

    For the three months ended December 31, 1999, service revenues decreased
sequentially due to the effect of Year 2000 issues. Many clients postponed the
start of any new service engagements scheduled to begin in November and
December 1999 and instead started these engagements in the first quarter of
2000. Training revenues, which are a component of service revenues, also
decreased for the same reasons. The overall gross margin decreased in quarters
ending June 1999 through December 1999 as a result of increased costs related to
our acquisition of Quantum Consulting Associates, Inc. The acquisition of
Quantum allowed us to enhance our offering of management consulting services. We
have continued to hire personnel and enhance our capabilities in this area
through December 1999. Our gross margin was most negatively affected in the
quarter ended December 1999 as a combined result of decreased service revenues
related to Year 2000 issues and increased costs related to our acquisition of
Quantum.

    Other factors that could affect our quarterly operating results include
those described below and elsewhere in this prospectus:

    - Our ability to attract new clients and retain current clients which could
      lead to changes in our revenues;

    - The announcement or introduction of new products or services by us or our
      competitors which could also lead to changes in our revenues;

    - Changes in the pricing of our products and services or those of our
      competitors;

    - Variability in the mix of our subscription/transaction and service
      revenues in any quarter which could affect our margins; and

    - The amount and timing of operating expenses and capital expenditures
      relating to expansion of our business.

    We believe that, while the quarterly period to period comparisons furnish
important information about our revenues and expenses, these comparisons are not
necessarily meaningful and should not be relied upon as indicators of future
performance. Finally, as a result of these foregoing factors, our annual or
quarterly results of operations may be below the expectations of the public
market analysts or investors. If this occurs, the market price of our common
stock may decline.

LIQUIDITY AND CAPITAL RESOURCES

    We have primarily financed our operations through private sales of
convertible preferred stock, borrowings under our line of credit and capital
lease obligations, and net revenues generated from our business. Through
December 31, 1999 we have raised cumulative net proceeds of approximately
$26.2 million through convertible preferred stock offerings. As of December 31,
1999 we had cash and cash equivalents of approximately $961,000 plus short term
investments of approximately $3.9 million, an accumulated deficit of
approximately $53.5 million and a working capital deficit of approximately
$3.8 million. In February 2000, we raised additional funds of approximately
$17.0 million from the issuance of Series E convertible preferred stock.

    Net cash used in operating activities totaled approximately $5.5 million in
1997, $3.9 million in 1998, and $5.7 million in 1999. Net cash flows from
operating activities in each period reflect net losses of approximately
$9.3 million in 1997, $8.3 million in 1998, and $10.5 million in 1999, and to a
lesser extent, are offset by the non-cash expenses relating to depreciation and
amortization, provision for allowance for doubtful accounts, and stock option
compensation. In addition the net

                                       29
<PAGE>
cash used in operations was increased by the growth in accounts receivable and
decreased by the growth in accounts payable, accrued compensation and deferred
revenues.

    Net cash used in investing activities totaled approximately $1.2 million in
1997, $3.8 million in 1998, and $5.0 million in 1999. Our investing activities
reflect the additions of property and equipment, purchases of investments, and
the acquisition of subsidiaries completed during 1999. We also anticipate that
our capital expenditures will increase over the next several years as we expand
our facilities and acquire equipment to support expansion of our sales,
marketing, and research and development activities.

    Our financing activities provided cash of approximately $6.8 million in
1997, $14.0 million in 1998, and $3.8 million in 1999. These positive financing
cash flows primarily reflect the net proceeds from the issuance of redeemable
convertible preferred stock, and from the issuance of the line of credit and
capital lease obligations.

    Amounts borrowed from one lending institution for capital leases are due
over 36 to 48 month repayment periods and are collateralized by our software
products. As of December 31, 1997, 1998, and 1999 the outstanding balance under
this equipment line of credit was approximately $612,000, $1.3 million, and
$940,000, respectively.

    In March 1999, we terminated the line of credit and negotiated with a
different bank a $2.5 million secured revolving credit facility and a
$1.5 million equipment line of credit. The line bears interest at prime rate
plus 0.75% percent for the secured revolving credit facility and prime rate plus
0.85% percent for the equipment line of credit. In September 1999, we negotiated
to increase the equipment line to $3.0 million. As of December 31, 1999 the
outstanding balance under this equipment line of credit was approximately
$1.7 million.

    In March 2000, we renegotiated the financial covenants applicable to our
secured revolving credit facility and increased our aggregate borrowing limit
under the equipment line of credit to $4.8 million. One of these financial
covenants restricts us from incurring operating losses in excess of $5,000,000
for each of the second, third and fourth quarters of 2000, and $2,000,000 in any
quarters thereafter. Commencing with the first quarter of 2002, we are
restricted from incurring operating losses in any two consecutive quarters.
Additionally, we are required to maintain a "quick ratio," as defined in the
loan documents, of at least 1.25 at all times, as well as specific minimum
tangible net worth amounts on specified future dates.

    Our secured revolving credit facility expires on September 5, 2000. The
amounts borrowed under the equipment line are initially subject to interest-only
payments and after the interest-only period will be repayable over a three-year
time period.

    We intend to continue the investment in the business, particularly in the
areas of research and development, sales, and marketing. Our future liquidity
and capital requirements will depend on numerous factors, including:

    - The costs and timing of expansion of sales and marketing activities;

    - The costs and timing of product development efforts and the success of
      these development efforts;

    - The extent to which our existing and new products and services gain market
      acceptance;

    - The level and timing of revenues;

    - The costs involved in maintaining and enforcing intellectual property
      rights;

    - The timing of market developments; and

    - Available borrowings under line of credit and capital lease arrangements.

                                       30
<PAGE>
    In addition, we may use cash resources to fund acquisitions of complementary
businesses and technologies; however, we currently have no commitments or
agreements and are not involved in any negotiations regarding any of these
transactions. We believe that the net proceeds from this offering, combined with
current cash resources, will be sufficient to meet our working capital and
capital expenditures for at least the next 12 months. Thereafter, we may find it
necessary to obtain additional equity or debt financing. In the event that
additional financing is required, we may not be able to raise it on terms
acceptable to us, if at all.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board, or FASB, issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities," which
establishes accounting and reporting standards for derivative securities
instruments and hedging activities. It requires an entity to recognize all
derivatives as either assets or liabilities in the balance sheet and measure
those instruments at fair value. As we do not engage in derivative or hedging
activities, we do not expect the adoption of this standard to have a significant
impact on our financial statements.

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

    We develop products in the United States and market our products in North
America, and to a lesser extent, Europe and the Asia-Pacific region. As a
result, our financial results could be affected by factors such as changes in
foreign currency exchange rates or weak economic conditions in foreign markets.
As a majority of sales are currently made in U.S. dollars, a strengthening of
the dollar could make our products less competitive in foreign markets. We do
not expect any material adverse effect on our consolidated financial position,
results of operations or cash flows due to movements in any specific foreign
currency.

    We currently do not use financial instruments to hedge operating expenses by
our European subsidiary. We intend to assess the need to utilize financial
instruments to hedge currency exposures on an ongoing basis. Our interest income
is sensitive to changes in the general level of U.S. interest rates,
particularly since the majority of our investments are in short-term
instruments. Due to the short-term nature of our investments, we believe that
there is no material risk exposure. Therefore, no quantitative tabular
disclosures are required.

                                  OUR BUSINESS

OVERVIEW

    We are a leading provider of solutions for global trade management. Our
offerings include an extensive library of global trade content, web-based B2B
solutions, management consulting and solution services. Global trade involves
the physical movement of goods across country borders, the management of the
information and processes required to enable global trade and the financial
exchange process required to complete related transactions. Our solutions focus
on the management of information and processes required to enable global trade
while enhancing collaboration across a client's global trade network, which
consists of exporters, forwarders, carriers, brokers, importers, banks and
customs or regulatory agencies. These offerings address the need for all members
of the global trade network to automate and optimize the multiple functions
associated with global trade. The core of our entire solutions suite is our
extensive library of trade content that leverages a sophisticated, rules-based
engine and unique trade expertise to deliver a web-based solution that enables
clients to automate their complex import and export needs. Our primary
Internet-based delivery mechanism for our solutions is our web-based portal,
TradePrism.com.

    We believe the dynamics of global trade present both compelling
opportunities and challenges for companies participating in the global
marketplace. Global trade is complex and resource-intensive and has largely
remained a manual and inefficient process. The Internet and e-commerce provide
further opportunities for global expansion but also present significant
operational challenges. Our solutions enable clients to address these
difficulties and inefficiencies in order to capitalize on the large, highly
fragmented and rapidly growing opportunity that global e-commerce presents.

    We serve an international client base of over 200 companies, some of whom
include Dell, Lucent, Microsoft, Nike, the New Zealand Dairy Board, Nortel,
Robert Bosch and Silicon Graphics. We provide comprehensive import and export
content to enable global trade management for transactions accounting for
approximately $4.1 trillion of all global trade in 1999. In addition, our
clients currently utilize our solutions to ship to over 120 countries worldwide.

    We provide integrated B2B solutions for vertical Internet trading markets
such as CatalogCity.com, RightFreight.com, SupplierMarket.com and Arzoon.com and
are continuing to develop our B2B solutions to meet the needs of specific
vertical industries. To facilitate the marketing and delivery of our solutions,
we also maintain relationships with a number of leading technology companies,
including IBM, JD Edwards, Oracle and Sun Microsystems.

INDUSTRY BACKGROUND

    The impact of multilateral trade agreements, the expansion of the modern
supply chain, competitive pressures and the rapid growth of e-commerce are
accelerating the pace of corporate globalization. The volume of global trade has
increased significantly over the last several decades and has reached an
unprecedented level in terms of both the number and size of transactions. The
World Trade Organization reported that world trade increased from $4.1 trillion
in 1980 to nearly $11.0 trillion in 1998. The U.S. Customs Service predicts that
U.S. imports alone will rise from more than $1 trillion in 1999 to approximately
$2 trillion by 2005. The U.S. Customs Service also projects that formal customs
entries will increase from approximately 18 million in 1999 to over 30 million
in 2005. As a result of this globalization, we believe the resources and
expertise necessary to manage global trade will increase significantly.

DIFFICULTIES OF GLOBAL TRADE

    COMPLEX NETWORK.  The modern global marketplace is a fast-paced, complex
trade network. Global trade involves an extended and geographically disperse
network of exporters, forwarders, carriers, brokers, importers, banks and
customs and regulatory agencies. These participants must be coordinated to
manage difficult physical, financial and information flows while satisfying
extensive country-specific trade requirements. These complex processes include
classifying and screening orders, determining and applying for required
licenses, generating and submitting extensive documentation, managing and
minimizing country-specific tariffs and duties, and tracking and tracing
shipments across the entire global trade network. Furthermore, trade
requirements are unique for every country, often undocumented, constantly
changing and difficult to interpret.

    COMPLIANCE BURDEN.  The burden of responsibility for regulatory compliance
and documentation weighs heavily on all members of the global trade network. The
U.S. Customs Service audits companies engaging in global trade. These audits
take an average of 15 months to complete and require an average of 1900 audit
hours. If caught in violation of international trade regulations, companies face
a variety of possible penalties and negative consequences, including fines, loss
of import/export privileges and adverse publicity. As a result, companies must
maintain an appropriate global trade compliance program to understand who is
buying their products and the end use of their products.

INEFFICIENCIES OF GLOBAL TRADE

    INADEQUATE INFRASTRUCTURE AND PROCEDURES.  Intense global competition is
requiring businesses to collaborate effectively with members of their global
trade network and to efficiently manage, optimize and utilize information flows.
For example, companies are finding it necessary to collaborate with trading
partners to take advantage of preferential trade programs such as those
promulgated under the North American Free Trade Agreement, or NAFTA. In
addition, companies are maintaining buffer inventory because their clients
demand heightened predictability and timely delivery. Customers are also
demanding heightened predictability and timely delivery, including real-time
tracking of shipments. Historically, businesses have lacked the technology and
procedures necessary to capitalize fully on the growth opportunities presented
by globalization. For example, Forrester Research estimates that 46% of
Internet-based orders to the U.S. from international clients go unfilled because
companies lack the procedures for international fulfillment.

    RESOURCE-INTENSIVE.  The resource demands for global trade management are
extensive, and existing trade compliance procedures, which are largely manual
and paper-based, tend to be highly inefficient and error-prone. Many companies
engaging in global trade cannot maintain large in-house staffs. Therefore, they
are required to outsource trade compliance and documentation processes to
third-party logistics firms or forwarders/brokers for a substantial fee. While
trade agreements such as NAFTA have removed barriers to global trade,
record-keeping requirements continue to increase substantially. Furthermore,
Benchmarking Partners estimates that up to 25% of a company's international
inventory is maintained as surplus stock due primarily to the inefficiencies of
global trade.

THE ROLE OF THE INTERNET

    The rapid growth of the Internet as a global medium through which businesses
communicate, share information and conduct business internally and directly with
their customers, suppliers and other business partners worldwide has further
hastened this era of escalating global competition. Forrester Research estimates
that B2B commerce will grow from approximately $406 billion in 2000 to
approximately $2.7 trillion in 2004. Furthermore, the Internet provides the
opportunity for

                                       33
<PAGE>
organizations to pursue solutions which automate and optimize the global trade
management processes.

MARKET OPPORTUNITY

    We believe companies seeking to realize the benefits of global trade
management require solutions that address the following concerns:

    LACK OF CENTRALIZED, COMPREHENSIVE AND CURRENT GLOBAL TRADE CONTENT. A
central, up-to-date library of global trade content is difficult to create and
maintain. As a result, there is a lack of a central source for this information.
Consequently, many multi-national companies resort to purchasing niche trade
solutions that cover only a limited number of countries or engage consulting
organizations specializing in selected countries to improve their global trade
practices. Given these deficiencies, we believe that companies are unable to
optimize decision-making based on access to dynamic centralized global trade
information.

    LIMITED FUNCTIONAL SOLUTIONS FOR GLOBAL TRADE MANAGEMENT.  In addition to
lacking comprehensive global trade content, currently available solutions lack
the breadth of functionality for clients to effectively manage their global
trade processes. For example, these solutions may address only limited global
trade functions, such as export document generation or import duty calculation.
Furthermore, these solutions may address the requirements of only one or a few
of the participants within the global trade network. Finally, many of these
solutions lack the technical architecture to operate over the Internet and do
not provide the portal capabilities necessary to facilitate global collaboration
of the trade network.

    TRADE EXPERTISE ACROSS GEOGRAPHIC AND VERTICAL MARKETS.  Companies offering
global trade consulting services typically focus on only one part of the
process, such as logistics or trade regulations, or only on a limited number of
industries, with very little understanding of the trade-specific implications of
their recommendations. Traditional consulting firms do not possess the
operational knowledge required to optimize global trade practices for clients
across the entire global trade network.

    NEED FOR COMPREHENSIVE SOLUTION SERVICES.  The resources required to manage
global trade effectively are extensive and include global trade expertise,
software solutions and related information technology infrastructure and
personnel to implement these solutions. Companies are frequently seeking
comprehensive outsourced solutions from third parties to satisfy their global
trade management needs because of the high costs and resource demands associated
with maintaining an in-house global trade department.

OUR SOLUTIONS

    We believe that we are the only company offering a comprehensive suite of
global trade management solutions that address all of these needs. The
fundamental elements of our solutions include:

    CENTRALIZED, COMPREHENSIVE AND CURRENT GLOBAL TRADE CONTENT.  Our extensive
and actively managed library of country-specific trade requirements is the core
of our entire suite of global trade management solutions. We leverage our unique
global trade expertise and a sophisticated rules-based engine to deliver
accurate, comprehensive, up-to-date global trade information to our clients via
a web-based portal.

    SOPHISTICATED, WEB-BASED B2B SOLUTIONS.  We offer a sophisticated suite of
web-based, B2B solutions for global trade management. Our B2B solutions enable
clients to automate and optimize information management procedures across their
entire global trade networks. In addition, our

                                       34
<PAGE>
solutions address the requirements of multiple members of a client's extended
global trade network and enable collaboration among all of these participants.

    INDUSTRY AND COUNTRY-SPECIFIC GLOBAL TRADE EXPERTISE.  Our management
consulting professionals analyze and address the global trade practices and
opportunities of our clients. Our consulting services help companies effectively
enter new geographic markets, better serve existing markets and address areas of
compliance risk. As part of our consulting offerings, we design, recommend and
implement process improvements for our clients.

    COMPREHENSIVE SOLUTION SERVICES.  Our solution services leverage
sophisticated technology, intellectual property and trade expertise to enable
our clients to outsource the information and process management required to
trade globally. These services enable clients to outsource all or parts of their
trade management procedures which allows them to focus on their core
competencies and realize financial benefits associated with efficient and
effective global trade management.

    Our suite of global trade management solutions provides our clients with the
following benefits:

    INFRASTRUCTURE TO PURSUE GLOBAL GROWTH OPPORTUNITIES.  Our global trade
solutions leverage our global trade expertise and web-based functionality to
simplify many of the complexities associated with global trade management.
Because our web-based solutions are flexible and modular, our clients can select
specific components, or engines, to address their particular global trade needs.
They may also choose to outsource the management of all or parts of their global
trade network to us. Because our solutions automate these processes, our clients
can focus on their core competencies and compete more effectively in the global
marketplace.

    EASY ACCESS TO RELIABLE GLOBAL TRADE CONTENT.  We constantly monitor and
interpret global trade rules and regulations and deliver them to our clients
through a dynamic web-based portal, which fully integrates with our B2B
solutions. We believe that our ability to provide our clients with access to
current, centralized and standardized trade requirements differentiates us in
the marketplace.

    TECHNOLOGY ENHANCING B2B COLLABORATION.  Our solutions suite provides a
platform for clients to collaborate in real-time over the Internet with members
of their global trade network. Our Internet architecture includes XML technology
that enables our clients to exchange information with their trade partners,
regardless of differing information technology infrastructures, systems or
software. Our web-based solutions are flexible, scalable and user-friendly,
which we believe will facilitate their acceptance across extended members of a
company's global trade network. This improved collaboration enables our clients
to more effectively move goods globally and strategically manage information
required in their global trade process.

    AUTOMATION AND OPTIMIZATION OF RESOURCE-INTENSIVE PROCEDURES.  By automating
and optimizing currently inefficient procedures, our solutions enable companies
to enhance revenue opportunities, increase operational efficiencies and reduce
the costs of global sourcing. These benefits enable clients to more effectively
and efficiently compete in the global marketplace.

    MANAGEMENT OF THE GLOBAL TRADE COMPLIANCE BURDEN.  By automating regulatory
compliance and documentation procedures, our solutions help clients protect
against potential fines, sanctions and business risks that may result from
noncompliant or inefficient global trade management systems.

    LEVERAGING OF INFORMATION TECHNOLOGY INVESTMENTS.  Our web-based platform is
designed to integrate existing information management systems and software
applications and work within the capacity of existing networks. The ability of
our products to integrate existing information systems

                                       35
<PAGE>
and software applications enables our clients to preserve and build upon their
corporate knowledge and information technology investments, while realizing the
benefits of our web-based solutions.

OUR STRATEGY

    We seek to be the leading provider of web-based, B2B solutions for global
trade information management. The key elements of our strategy include:

    BECOME THE STANDARD AND PREEMINENT BRAND FOR GLOBAL TRADE MANAGEMENT.  We
seek to serve as the information backbone for global trade management. We expect
to expand our offerings of web-based trade information to cover countries
engaged in over 75% of the world's global trade transactions. We plan to
complement our solutions suite with an aggressive global branding campaign that
leverages our strategic alliances and relationships with clients, governments
and industry consultants. Moreover, we intend to provide solutions to all
members of the global trade network, positioning us to be recognized as the
standard for global trade management.

    EXPAND GLOBAL TRADE CONTENT AND ENHANCE SOLUTIONS OFFERINGS.  We intend to
continue to develop a comprehensive suite of solutions with features,
functionality and services that allow companies of all sizes to manage the
complexities of global trade. Because access to reliable, up-to-date
country-specific trade requirements is essential to companies engaging in global
trade, we intend to fortify our trade content by continuing to hire top global
trade experts worldwide. We plan to continue developing various components of
our B2B solutions to address the specific needs of various industries and trade
participants. We also intend to provide packaged solutions that are tailored to
provide immediate value to companies in specific industries, as well as
mid-market solutions that are competitively priced, quickly deployed and easily
managed. In addition to in-house product development, we intend to supplement
these initiatives by evaluating opportunities for acquisitions and strategic
investments.

    ENHANCE TRANSACTION-BASED REVENUE STREAM.  We will continue to provide
integrated solutions for industry-leading web-based B2B and B2C e-commerce
marketplaces. These marketplaces require global trade management solutions to
enable the cross-border movement of goods between buyers and sellers. We plan to
derive primarily transaction-based revenues from these Internet trading markets.
As these marketplaces add new clients that trade globally, we will, in turn,
receive a recurring revenue benefit of those new clients executing transactions
using our engines.

    EXPAND OUR REACH AND RANGE.  We intend to continue expanding our global
presence to enhance our competitive position worldwide and our ability to serve
and support our clients. We anticipate expanding our sales, marketing and
services presence in strategically important geographic markets. In addition, we
intend to utilize our strategic alliances and our relationships with leaders
within specific vertical markets that have strong potential for global
expansion. We also intend to evaluate opportunities for acquisitions and
investments that can accelerate our global expansion.

    EXPAND OUR SOLUTION SERVICES CAPABILITIES.  We intend to invest actively in
our solution services offerings in order to capitalize on a growing demand for
outsourced trade management solutions. We will continue to provide solution
services that will enable companies to outsource all or parts of their global
trade functions. These offerings target clients ranging from the Fortune 500 to
Internet start-ups and will be customized to an individual client or provided as
a shared service.

PRODUCTS AND SERVICES

    Our comprehensive web-based solutions for global trade management consist of
our library of trade regulations, called Global eContent, our web-based B2B
solutions, including TradeSphere and TradePrism.com, our management consulting
services, called TradeValue, and our solution services,

clients a unique solution to automate and optimize their global trade process.

GLOBAL ECONTENT

    Global eContent is a dynamic library of country-specific trade requirements
that is available to our clients. This extensive base of electronic content
serves as the platform for our entire suite of global trade management
solutions. Because of the global trade expertise and specialization required to
interpret and fully understand the impact of country-specific trade regulations,
we employ a full-time content and compliance team dedicated exclusively to
tracking and managing trade regulations, trade content and international
regulatory data. These full-time Global eContent experts also design
intelligence into the data to be leveraged by our B2B solutions (e.g.,
algorithms which can detect restricted parties even if names or addresses are
misspelled, or logic which can search for lower duty rates given preferential
programs such as NAFTA and others). This team consists of former government
compliance officials, international lawyers, licensed customs brokers,
in-country data experts, industry consultants and individuals with previous
responsibility for managing import and export functions within multi-national
organizations in various industries.

    Periodic regulatory and policy changes require that our B2B solutions be
updated on a regular basis to keep current with the latest country-specific
trade regulations. To meet this need, daily updates and postings are made
available through TradePrism.com, our web-based portal, from which updates and
changes can be electronically downloaded and applied. Information provided in
our Global eContent library includes trade data, regulation updates, regulation
notices, trade committee meeting information, requests for public comment on
regulatory issues and final rulings on proposed regulation.

    The following table lists the countries for which we provide Global eContent
support. The level of data we provide varies by country and ranges from simple
references to extensive import and export regulations.

    - Managing a client's entire global trade operation.

SALES AND MARKETING

    We market and sell our solutions through our direct sales force, resellers,
B2B marketplaces and strategic alliances. Our marketing organization is
responsible for educating the marketplace, generating leads, communicating with
market analysts, working with complementary technology and consulting partners
and creating sales programs and literature. In addition to our internal
resources, we rely on third parties such as public relations firms and graphic
design firms to assist us with our marketing campaigns.

    As of March 31, 2000, our direct sales organization consisted of a total of
46 sales and marketing personnel. In addition to the direct sales force, members
from other departments within Vastera contribute to the sales effort at various
stages in the sales cycle.

    Our marketing professionals assist in generating new sales opportunities by
creating various marketing programs, updating our web site and hosting or
sponsoring various events. We participate in a number of trade shows and
industry events. We also provide speakers from our company and our clients to
represent us in a number of industry forums. We host monthly teleconferences led
by individual experts focused on educating individuals involved in global trade
operations for companies worldwide. Our public relations plan is designed to
convey our messages to appropriate audiences and we reinforce these efforts
through our ongoing communications with a number of key industry analysts and
press representatives.

STRATEGIC ALLIANCES

    The principal goals of our strategic alliances are to accelerate the global
market acceptance of our solutions, to extend our global resources and to help
our clients realize the benefits of our solutions quickly. Our strategic

      Microsoft, and serve as an original equipment manufacturer, or OEM, for
      IBM WebSphere.

    - We have marketing certifications of varying degrees from a number of
      enterprise resource planning, or ERP, companies including SAP, Oracle,
      Baan and JD Edwards.

                                       41
<PAGE>
    - We have reseller agreements with i2 Technologies and EXE Technologies.

    - We have strategic alliances with a number of consulting companies
      including Andersen Consulting and KPMG Peat Marwick.

PRODUCT DEVELOPMENT

    Our product engineering team is made up of over 68 professionals focused on
new and developing B2B solutions. Our product engineers are organized into the
following groups: quality assurance, documentation, release management, solution
development and sustaining engineering. Our solution development is structured
around project teams that are comprised of developers led by a senior
development manager responsible for delivering a defined solution engine. This
structure allows for the organization to quickly scale and allows us to
outsource non-critical development activities when necessary to bring products
to market quickly. These dedicated product engineers are partnered with a
product management team consisting of experienced global trade professionals who
set the product plan and requirements based on our business plan and market
dynamics. Our engines are tied into the complete TradeSphere suite through
process and specifications defined and managed by our infrastructure and
integration team.

    In addition, our Global eContent development methodology and approach allows
us to deliver market leading solutions for import and export management for
specific countries. This effort requires synthesizing an often lengthy export or
import manual into a set of requirements that then are integrated with our
rules-based Global eContent engine. In addition, these solutions are designed so
that we can readily provide updates for frequent country regulation changes. We
believe our product development professionals, teamed with our 35 product
management trade professionals, allow us to provide robust, market-driven,
web-based technology solutions that are reliable and scalable.

    Our research and development expenses totaled $6.2 million for the year
ended December 31, 1999, which represented 32% of our total revenues. We expect
to significantly increase our research and development efforts in future years.

as emerging Internet portals and marketplaces.

CASE STUDIES

NORTEL

    CHALLENGE:  Prior to implementing our solutions, Nortel handled its global
trade management functions either manually or through a variety of internally
developed systems. As Nortel's business increased and the number of
international shipments grew, Nortel experienced challenges generating the
volume of global trade documentation required, which resulted in delayed
deliveries as goods were held up in customs. Another issue was the lack of
product visibility within Nortel's own global network of over 90 shipping sites
as well as across its global trade network.

    SOLUTION:  Our solutions were first implemented in 1993 and are now Nortel's
standard for global trade management. Our solutions have been deployed in the
United States, Canada, UK, Mexico, Brazil, Malaysia and Singapore. In late 1999,
Nortel purchased a subscription for TradeSphere and other web-based global trade
collaboration capabilities.

    RESULTS:  Our solutions have reduced Nortel's costs and improved global
trade information and time to market, resulting in more than $9.4 million of
value over two years. Our solutions were cited by Nortel as the project with the
highest return on investment for 1997.

                                       43
<PAGE>
NEW ZEALAND DAIRY BOARD

    CHALLENGE:  The New Zealand Dairy Board (NZDB) is the world's largest single
dairy exporter, shipping more than 4,000 products to over 1,000 destination
ports in over 120 countries across six continents. Prior to implementing our
solutions, the NZDB maintained a 10-year-old legacy system and relied heavily on
contractors to modify this system. It also relied on frequent manual
intervention to handle business functions not addressed by its legacy system.
Each of the NZDB's international shipments averaged 12 documents. Adding further
complexity to the NZDB's global trade operations were frequent changes to
international shipping documents and regulations imposed by governments around
the world in an effort to protect their local dairy businesses. The NZDB
recognized that it could not continue to generate and update the necessary
country-specific shipping documents and trade regulations by simply adding
personnel.

    SOLUTION:  Our solutions were implemented in 1998 as the NZDB worldwide
standard for global trade management. The implementation of our solutions was
completed in less than six months.

    RESULTS:  Our solutions reduced the total number of source shipping
documents at the NZDB from over 5,000 to fewer than 300. In 1999, unlike
previous years, there were no late shipment dispatches caused by export
documentation errors. By utilizing our global trade solutions, the NZDB was able
to manage an estimated 300,000 ton increase in exports to approximately
1.3 million tons for the fiscal year ending in May 2000.

RIGHTFREIGHT.COM

    CHALLENGE:  RightFreight.com is an Internet-based B2B airfreight services
exchange, providing reverse auctions for carrier services including contract and
spot shipment proposal processing. To differentiate its offering,
RightFreight.com needed to determine how to address global trade in its business
processes and offer more value-added services to its clients.

    SOLUTION:  In December 1999, RightFreight.com selected our solution to
provide embedded and hosted global trade management capabilities. Our
TradeSphere solutions allowed for fast time-to-market and provided mission
critical global trade functions and value-added services such as restricted
party screening, landed-cost information and international document generation.

    RESULTS:  In less than eight weeks, RightFreight.com was able to create a
B2B exchange that included global trade capabilities by leveraging our global
trade expertise and extensive research and development investment.

COMPETITION

    Our market is intensely competitive, evolving and highly fragmented. We
expect the intensity of competition to increase in the future. We face
competition from third-party development efforts, consulting companies and
in-house development efforts. We expect that these parties will continue to be a
principal source of competition for the foreseeable future. Our principal
competitors by solution segment include:

    - Content aggregators such as Dun & Bradstreet and TradeCompass;

    - International trade logistics providers such as Capstan, Nextlinx,
      Rockport and Syntra;

    - Trade consultants such as management consulting firms, law firms and
      boutique consulting firms; and

    - Outsourcing service providers such as third party logistics providers,
      fourth party logistics providers and carriers.

                                       44
<PAGE>
    We believe that the principal competitive factors affecting our market
include a referenceable client base, the breadth and depth of a given solution,
product quality and performance, customer service, core technology, product
scalability and reliability, product features, the ability to implement
solutions and the value of a given solution. Although we believe our solutions
currently compete favorably with respect to these factors, our market is
relatively new and is evolving rapidly. We may not be able to maintain our
competitive position against current and potential competitors, especially those
with significantly greater financial, marketing, service, support, technical and
other resources.

    Many of our competitors and potential competitors have longer operating
histories, significantly greater financial, technical, marketing and other
resources, greater name recognition, global presence and established channel
partners, a broader range of products to offer, and a larger installed base of
clients than us, each of which could provide them with a significant competitive
advantage over us. In addition, we expect to experience increased price
competition as competitors compete for market share. It is possible that new
competitors or alliances among competitors may emerge and rapidly acquire
significant market share. We may not be able to compete successfully with
existing or new competitors and this competition may have a material adverse
effect on our business.

TECHNOLOGY

    Our B2B solutions are based on leading edge technology, enabling us to
deliver high performance, scalable, flexible and interoperable B2B solutions.
Our B2B solutions are built using a browser-based user interface, or UI, XML
integration technology and are also offered with a traditional Windows or
Motif-based UI. Our TradeSphere architecture supports the client demand for
configurability, electronic updates to country-specific content and plug-in
additions for new countries, functions and content.

    For our web-based solutions infrastructure, we utilize IBM's WebSphere,
HTML/DHTML, Java and Enterprise Java Beans, MQ Systems Integration Series and
XML. We incorporate a SmarteLink architecture that facilitates XML integration
and also leverages our repository of Forte-developed C++ applications allowing
interoperability with our web-based applications.

    Unique to the TradeSphere design and implementation approach is that both
content rules and configurations or installation-specific options are stored as
metadata within the solution's database. This approach supports a single source
solution which is able to operate on multiple hardware platforms, operating
environments and database platforms. Currently supported environments include
Windows NT and UNIX operating environments based on Sun Solaris, IBM AIX and
HP-UX platforms. Currently supported relational databases include either the
Oracle or SQL Server. Current user interfaces include a web-browser, Windows NT
and Motif. The system also supports multiple languages including double byte
languages.

INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS

    We rely primarily on a combination of copyright, trade secret and trademark
laws, confidentiality agreements with employees and third parties, and
protective contractual provisions contained in license agreements with
consultants, vendors and clients to protect our proprietary rights.

    We have registered the trademark Vastera in the United States. We have also
filed federal trademark applications with respect to Global Trade Management,
Global Trade Value Chain, TradeSphere, TradeValue, TradeVantage, TradePrism,
Global eContent, TradeAxiom, Opening the World to eBusiness, Global Passport,
Smarte Commerce, Smarte Contents, Smarte Methods and SmartWare. The Vastera logo
is also a trademark of Vastera, Inc.

    We believe the strength of our trademarks and service marks benefits our
business and we intend to continue to protect our registered and common law
trademarks and service marks in the United States and abroad. We have not
secured registration of all of our marks in the United States and have not
pursued registration in any foreign country.

    We also protect our proprietary rights by requiring employees to agree not
to reveal any proprietary information to our competitors and to sign a
confidentiality agreement. Employees also are required to execute a
non-competition agreement, which restricts them from working for a competitor
for one year after termination of employment with us. However, we may not obtain
these agreements in every case.

    We incorporate technology from third parties into our software. We currently
have non-exclusive license agreements with Forte Software, Inc. and IBM for the
use of their technology in our global trade management solutions.

EMPLOYEES

    As of March 31, 2000, we had 230 employees. Our employees are not
represented by any collective bargaining agreement and we have never experienced
a work stoppage. We believe our relations with our employees are good.

FACILITIES

    Our principal administrative, sales, marketing, technical support and
product development facilities are located at our headquarters in Dulles,
Virginia. We currently occupy approximately 50,000 square feet of office space
in the Dulles facility under a lease that terminates on October 31, 2002. We
also lease office space for sales, marketing and consulting activities outside
of San Francisco, outside of Denver and outside of London in the United Kingdom.

    The exercise price per share of each option was equal to the fair market
value of the common stock on the grant date as determined by the board of
directors. We have never granted any stock appreciation rights. The potential
realizable values assume that the options' price per share was the fair market
value of the common stock on the date of grant. This potential realizable value
also assumes that the price of the stock appreciates at rates of 5% and 10%
compounded annually from the date the options were granted until their
expiration date. These numbers are calculated based on the requirements of the
Securities and Exchange Commission and do not reflect our estimate of future
stock price growth. Actual gains, if any, on stock option exercises will depend
on the future performance of the common stock and the date on which the options
are exercised.

AGGREGATED OPTION EXERCISES AND VALUES IN FISCAL YEAR ENDED DECEMBER 31, 1999

    The following table sets forth information containing the value realized

1996 STOCK OPTION PLAN

    Our board of directors and stockholders adopted and approved the 1996 Stock
Option Plan on July 26, 1996. The 1996 Plan provides for grants of incentive
stock options, nonqualified stock options and stock awards to employees,
directors, consultants and advisors. Members of the non-employee director
administrative committee are not eligible to receive options and awards. We may
issue options to purchase a maximum of 6,750,000 shares of common stock under
the 1996 Plan. The board of directors may not increase the maximum number of
shares without obtaining the approval of the stockholders. No options or awards
may be granted under the 1996 Plan after July 26, 2006.

    The 1996 Plan may be administered by the board of directors or by a
committee of non-employee directors. The plan administrator has the power to
determine the persons to whom, the times at which, and the price at which the
options and awards shall be granted, and to determine the type of option or
award to be granted and the number of shares subject to options and awards.

    The plan administrator determines the option price for options. For a
nonqualified stock option, the price shall be at least equal to 85% of the fair
market value of the shares on the date the option is granted. For an incentive
stock option, the price shall be at least 100% of the fair market value on the
date the option is granted. If a recipient of an incentive stock option owns
shares possessing more than 10% of the total voting power of all classes of
stock, the option price shall be at least 110% of the fair market value on the
grant date.

    Options expire not later than 10 years after the date of the grant or five
years after the date of grant if the recipient owns shares possessing more than
10% of the combined voting power of all classes of stock. Options expire
90 days from the date the recipient's employment or service with Vastera
terminates or 12 months after disability or death, unless the grant agreement or
plan administrator provides otherwise. Options are not transferable during the
lifetime of the recipient, except that a nonqualified stock option may be
transferred pursuant to the terms of a domestic relation's order, or otherwise
as provided in the grant agreement.

    The 1996 Plan provides that in the event of a change of control, the plan
administrator may take any appropriate action with respect to options, including
terminating options with 15 days' notice or causing options to become
immediately exercisable in full. In the event of a merger of Vastera into
another company or a sale of all or substantially all of the assets of Vastera,
options shall become immediately exercisable unless the successor company agrees
to assume the options or provide equivalent options.

                                       52
<PAGE>
    Awards of stock granted pursuant to the 1996 Plan shall be in the form of
written award agreements approved by the plan administrator. The plan
administrator may impose appropriate restrictions and forfeiture conditions on
stock awards.

    In the event that the outstanding shares are modified by reason of a
reorganization, merger, consolidation, recapitalization, reclassification, stock
split, combination or exchange of shares, the plan administrator shall make
appropriate adjustments to the aggregate number of shares available under the
1996 Plan, the number of shares outstanding and price per share of outstanding
options.

2000 STOCK OPTION/STOCK ISSUANCE PLAN

    INTRODUCTION.  Our 2000 Stock Option/Stock Issuance Plan is intended to
serve as the successor equity incentive program to our 1996 Plan. Our 2000 Plan
was adopted by our board on April 4, 2000 and approved by the stockholders in
April 2000. Our 2000 Plan will become effective on the date the underwriting
agreement for this offering is signed. At that time, all options available for
grant under the 1996 Plan will be transferred to our 2000 Plan, and no further
option grants will be made under that predecessor plan. The transferred options
will continue to be governed by their existing terms, unless our compensation
committee elects to extend one or more features of our 2000 Plan to those
options. Except as otherwise noted below, the transferred options will have
substantially the same terms as are in effect for grants made under the
discretionary option grant program of our 2000 Plan.

    SHARE RESERVE.  Under our 2000 Plan, 16,750,000 shares of common stock have
been authorized for issuance. This share reserve consists of the number of
shares we estimate will be carried over from our 1996 Plan, including the shares
subject to outstanding options thereunder, plus an additional increase of
approximately 10,000,000 shares. The number of shares of common stock reserved
for issuance under our 2000 Plan will automatically increase on the first
trading day in January each calendar year, beginning in calendar year 2001, by
an amount equal to 1.5% of the total number of shares of common stock
outstanding on the last trading day in December of the preceding calendar year,
but in no event will any such annual increase exceed 750,000 shares. In
addition, no participant in our 2000 Plan may be granted stock options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 500,000 shares of common stock per calendar year.

    EQUITY INCENTIVE PROGRAMS.  Our 2000 Plan is divided into five separate
components:

    - the discretionary option grant program, under which eligible individuals
      in our employ or service may be granted options to purchase shares of
      common stock at an exercise price not less than 100% of the fair market
      value of those shares on the grant date;

    - the stock issuance program, under which such individuals may be issued
      shares of common stock directly, through the purchase of such shares at a
      price not less than 100% of their fair market value at the time of
      issuance or as a bonus tied to the attainment of performance milestones or
      the completion of a specified period of service;

    - the salary investment option grant program, under which our executive
      officers and other highly compensated employees may be given the
      opportunity to apply a portion of their base salary to the acquisition of
      special below-market value stock option grants;

    - the automatic option grant program, under which option grants will
      automatically be made at periodic intervals to our non-employee board
      members to purchase shares of common stock at an exercise price equal to
      100% of the fair market value of those shares on the grant date; and

                                       53
<PAGE>
    - the director fee option grant program, under which our non-employee board
      members may be given the opportunity to apply a portion of the annual
      retainer fee otherwise payable to them in cash each year to the
      acquisition of special below-market value option grants.

    ELIGIBILITY.  The individuals eligible to participate in our 2000 Plan
include our officers and other employees, our non-employee board members and any
consultants we hire.

    ADMINISTRATION.  The discretionary option grant program and the stock
issuance program will be administered by the compensation committee. This
committee will determine which eligible individuals are to receive option grants
or stock issuances under those programs, the time or times when such option
grants or stock issuances are to be made, the number of shares subject to each
such grant or issuance, the status of any granted option as either an incentive
stock option or a nonstatutory stock option under the federal tax laws, the
vesting schedule to be in effect for the option grant or stock issuance and the
maximum term for which any granted option is to remain outstanding. The
compensation committee will also have the exclusive authority to select the
executive officers and other highly compensated employees who may participate in
the salary investment option grant program in the event that program is
activated for one or more calendar years.

    PLAN FEATURES.  Our 2000 Plan will include the following features:

    - The exercise price for the shares of common stock subject to option grants
      made under our 2000 Plan may be paid in cash or in shares of common stock
      valued at fair market value on the exercise date. The option may also be
      exercised through a same-day sale program without any cash outlay by the
      optionee. In addition, the plan administrator may provide financial
      assistance to one or more optionees in the exercise of their outstanding
      options or the purchase of their unvested shares by allowing such
      individuals to deliver a full-recourse, interest-bearing promissory note
      in payment of the exercise price and any associated withholding taxes
      incurred in connection with such exercise or purchase.

    - The compensation committee will have the authority to cancel outstanding
      options under the discretionary option grant program, including options
      transferred from the 1996 Plan, in return for the grant of new options for
      the same or a different number of option shares with an exercise price per
      share based upon the fair market value of our common stock on the new
      grant date.

    - Stock appreciation rights are authorized for issuance under the
      discretionary option grant program. Such rights will provide the holders
      with the election to surrender their outstanding options for an
      appreciation distribution from us equal to the fair market value of the
      vested shares of common stock subject to the surrendered option, less the
      aggregate exercise price payable for those shares. Such appreciation
      distribution may be made in cash or in shares of common stock. None of the
      outstanding options under our 1996 Plan contain any stock appreciation
      rights.

    - The 2000 Plan will include the following change in control provisions
      which may result in the accelerated vesting of outstanding option grants
      and stock issuances:

       - In the event that we are acquired by merger or asset sale, each
         outstanding option under the discretionary option grant program which
         is not to be assumed by the successor corporation will automatically
         accelerate in full, and all unvested shares under the discretionary
         option grant and stock issuance programs will immediately vest, except
         to the extent our repurchase rights with respect to those shares are to
         be assigned to the successor corporation.

                                       54
<PAGE>
       - The compensation committee will have complete discretion to structure
         one or more options under the discretionary option grant program so
         those options will vest as to all the option shares in the event those
         options are assumed in the acquisition but the optionee's service with
         us or the acquiring entity is subsequently terminated. The vesting of
         outstanding shares under the stock issuance program may be accelerated
         upon similar terms and conditions.

       - The compensation committee will also have the authority to grant
         options which will immediately vest in the event we are acquired,
         whether or not those options are assumed by the successor corporation.

       - The compensation committee may grant options and structure repurchase
         rights so that the shares subject to those options or repurchase rights
         will immediately vest in connection with a successful tender offer for
         more than 50% of our outstanding voting stock or a change in the
         majority of our board through one or more contested elections for board
         membership. Such accelerated vesting may occur either at the time of
         such transaction or upon the subsequent termination of the individual's
         service.

       - The options currently outstanding under our 1996 Plan will immediately
         vest in the event we are acquired by merger or sale of substantially
         all our assets, unless those options are assumed by the acquiring
         entity or our repurchase rights with respect to any unvested shares
         subject to those options are assigned to such entity.

    SALARY INVESTMENT OPTION GRANT PROGRAM.  In the event the compensation
committee elects to activate the salary investment option grant program for one
or more calendar years, each of our executive officers and other highly
compensated employees selected for participation may elect, prior to the start
of the calendar year, to reduce his or her base salary for that calendar year by
a specified dollar amount not less than $10,000 nor more than $50,000. Each
selected individual who files such a timely election will automatically be
granted, on the first trading day in January of the calendar year for which his
or her salary reduction is to be in effect, an option to purchase that number of
shares of common stock determined by dividing the salary reduction amount by
two-thirds of the fair market value per share of our common stock on the grant
date. The option will be exercisable at a price per share equal to one-third of
the fair market value of the option shares on the grant date. As a result, the
option will be structured so that the fair market value of the option shares on
the grant date less the exercise price payable for those shares will be equal to
the amount by which the optionee's salary is reduced under the program. The
option will become exercisable in a series of 12 equal monthly installments over
the calendar year for which the salary reduction is to be in effect.

    AUTOMATIC OPTION GRANT PROGRAM.  Under the automatic option grant program,
each individual who first becomes a non-employee board member at any time after
the completion of this offering will automatically receive an option grant for
             shares on the date such individual joins the board, provided such
individual has not been in our prior employ. In addition, on the date of each
annual stockholders meeting held after the completion of this offering, each
non-employee board member who is to continue to serve as a non-employee board
member, including each of our current non-employee board members, will
automatically be granted an option to purchase       shares of common stock,
provided such individual has served on our board for at least six months.

    Each automatic grant will have an exercise price per share equal to the fair
market value per share of our common stock on the grant date and will have a
term of 10 years, subject to earlier termination following the optionee's
cessation of board service. The option will be immediately exercisable for all
of the option shares; however, we may repurchase, at the exercise price paid per
share, any shares purchased under the option which are not vested at the time of
the optionee's

                                       55
<PAGE>
cessation of board service. The shares subject to each initial       -share
automatic option grant will vest in a series of four successive annual
installments upon the optionee's completion of each year of board service over
the four-year period measured from the grant date. The shares subject to each
annual       -share automatic option grant will vest upon the optionee's
completion of one year of board service measured from the grant date. However,
the shares will immediately vest in full upon certain changes in control or
ownership or upon the optionee's death or disability while a board member.

    DIRECTOR FEE OPTION GRANT PROGRAM.  Should the director fee option grant
program be activated in the future, each non-employee board member will have the
opportunity to apply all or a portion of any cash retainer fee for the year to
the acquisition of a below-market value option grant. The option grant will
automatically be made on the first trading day in January in the year for which
the retainer fee would otherwise be payable in cash. The option will have an
exercise price per share equal to one-third of the fair market value of the
option shares on the grant date, and the number of shares subject to the option
will be determined by dividing the amount of the retainer fee applied to the
program by two-thirds of the fair market value per share of our common stock on
the grant date. As a result, the option will be structured so that the fair
market value of the option shares on the grant date less the exercise price
payable for those shares will be equal to the portion of the retainer fee
applied to that option. The option will become exercisable in a series of 12
equal monthly installments over the calendar year for which the election is to
be in effect. However, the option will become immediately exercisable for all
the option shares upon the optionee's death or disability while serving as a
board member.

    Our 2000 Plan will also have the following features:

    - Outstanding options under the salary investment and director fee option
      grant programs will immediately vest if we are acquired by a merger or
      asset sale or if there is a successful tender offer for more than 50% of
      our outstanding voting stock or a change in the majority of our board
      through one or more contested elections.

    - Limited stock appreciation rights will automatically be included as part
      of each grant made under the salary investment option grant program and
      the automatic and director fee option grant programs, and these rights may
      also be granted to one or more officers as part of their option grants
      under the discretionary option grant program. Options with this feature
      may be surrendered to us upon the successful completion of a hostile
      tender offer for more than 50% of our outstanding voting stock. In return
      for the surrendered option, the optionee will be entitled to a cash
      distribution from us in an amount per surrendered option share based upon
      the highest price per share of our common stock paid in that tender offer.

    The board may amend or modify the 2000 Plan at any time, subject to any
required stockholder approval. The 2000 Plan will terminate no later than
             , 2010.

2000 EMPLOYEE STOCK PURCHASE PLAN

    INTRODUCTION.  Our 2000 Employee Stock Purchase Plan was adopted by the
board of directors on April 4, 2000 and approved by the stockholders in
             2000. The plan is administered by the Compensation Committee. The
plan will become effective immediately upon the signing of the underwriting
agreement for this offering. The plan is designed to allow our eligible
employees and the eligible employees of our participating subsidiaries to
purchase shares of common stock, at semi-annual intervals, with their
accumulated payroll deductions.

    SHARE RESERVE.  5,000,000 shares of our common stock will initially be
reserved for issuance. The reserve will automatically increase on the first
trading day in January each calendar year, beginning in calendar year 2001, by
an amount equal to 1.0% of the total number of outstanding

                                       56
<PAGE>
shares of our common stock on the last trading day in December in the prior
calendar year. In no event will any such annual increase exceed 500,000 shares.

    OFFERING PERIODS.  The plan will have a series of successive overlapping
offering periods, with a new offering period beginning on the first business day
of May and November each year. Each offering period will have a duration of
24 months, unless otherwise determined by the compensation committee. However,
the initial offering period may have a duration in excess of 24 months and will
start on the date the underwriting agreement for this offering is signed and
will end on the last business day in April 2002. The next offering period will
start on the first business day in May 2000.

    ELIGIBLE EMPLOYEES.  Individuals scheduled to work more than 20 hours per
week for more than 5 calendar months per year may join an offering period on the
start date of that period. However, employees may participate in only one
offering period at a time.

    PAYROLL DEDUCTIONS.  A participant may contribute up to 15% of his or her
cash earnings through payroll deductions, and the accumulated deductions will be
applied to the purchase of shares on each semi-annual purchase date. The
purchase price per share will be equal to 85% of the fair market value per share
on the participant's date of entry into the offering period or, if lower, 85% of
the fair market value per share on the semi-annual purchase date. Semi-annual
purchase dates will occur on the last business day of April and October each
year. However, a participant may not purchase more than       shares on any
purchase date, and not more than       shares may be purchased in total by all
participants on any purchase date. Our compensation committee will have the
authority to change these limitations for any subsequent offering period.

    RESET FEATURE.  If the fair market value per share of our common stock on
any purchase date is less than the fair market value per share on the start date
of the two-year offering period, then that offering period will automatically
terminate, and a new two-year offering period will begin on the next business
day. All participants in the terminated offering will be transferred to the new
offering period.

    CHANGE IN CONTROL.  Should we be acquired by merger or sale of substantially
all of our assets or more than fifty percent of our voting securities, then all
outstanding purchase rights will automatically be exercised immediately prior to
the effective date of the acquisition. The purchase price will be equal to 85%
of the market value per share on the participant's date of entry into the
offering period in which an acquisition occurs or, if lower, 85% of the fair
market value per share immediately prior to the acquisition.

    PLAN PROVISIONS.  The following provisions will also be in effect under the
plan:

    The plan will terminate no later than the last business day of April 2010.

    The board may at any time amend, suspend or discontinue the plan. However,
certain amendments may require stockholder approval.

401(K) PROFIT SHARING PLAN

    We have adopted a tax-qualified employee savings and retirement plan, the
401(k) Profit Sharing Plan, for eligible U.S. employees. Eligible employees may
elect to defer a portion of their eligible compensation, subject to the
statutorily prescribed annual limit. We may make matching contributions on
behalf of all participants who have elected to make deferrals to the 401(k)
Profit Sharing Plan in an amount determined annually by the Company. Any
contributions to the plan by the company or the participants are paid to a
trustee. The contributions made by the company, if any, are subject to a vesting
schedule; all other contributions are fully vested at all times. The 401(k)
Profit Sharing Plan, and the accompanying trust, are intended to qualify under
Sections

                                       57
<PAGE>
401(k) and 501 of the Internal Revenue Code, so that contributions by us or by
employees and income earned (if any) on plan contributions are not taxable to
employees until withdrawn and contributions by us, if any, will be deductible by
the company when made. At the direction of each participant, the trustee invests
the contributions made to the 401(k) Profit Sharing Plan in any number of
investment options.

LIMITATIONS ON LIABILITY OF DIRECTORS AND OFFICERS AND INDEMNIFICATION

    LIMITATION OF LIABILITY.  Our certificate of incorporation provides that our
officers and directors will not be personally liable to us or our stockholders
for monetary damages resulting from a breach of fiduciary duty, to the maximum
extent permitted by Delaware law. Under Delaware law, directors of a corporation
will not be personally liable for monetary damages for breach of their fiduciary
duties as directors, except for:

    - Any breach of the duty of loyalty to the corporation or its stockholders;

    - Acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of law;

    - Unlawful payments of dividends or unlawful stock repurchases or
      redemptions; or

    - Any transaction from which the director derived an improper personal
      benefit.

    This limitation of liability does not apply to non-monetary remedies that
may be available, such as injunctive relief or rescission, nor does it relieve
our officers and directors from complying with federal or state securities laws.

    INDEMNIFICATION.  Our certificate of incorporation and bylaws provide that
we shall indemnify our directors and executive officers, and may indemnify our
other corporate agents, to the fullest extent permitted by law. This provision
deters transactions not approved by the board, including transactions which may
offer a premium over market price for shares of common stock. An officer or
director shall not be entitled to indemnification if:

    - The officer or director did not act in good faith and in a manner
      reasonably believed to be in, or not opposed to our best interests; or

    - The officer or director is subject to criminal action or proceedings and
      had reasonable cause to believe the conduct was unlawful.

    We intend to enter into agreements to indemnify our directors and officers
in addition to the indemnification provided for in our certificate of
incorporation and our bylaws. These agreements, among other things, provide for
indemnification of our directors and officers for expenses specified in the
agreements, including attorneys' fees, judgments, fines and settlement amounts
incurred by any of these persons in any action or proceeding arising out of
these persons' services as a director or officer for us, any of our subsidiaries
or any other entity to which the person provides services at our request. We
believe that these provisions and agreements are necessary to attract and retain
qualified persons as directors and officers.

                             PRINCIPAL STOCKHOLDERS

    The following table sets forth information as of March 31, 2000 regarding
the beneficial ownership of our common stock by:

    - each person or entity who is known by us to own beneficially more than 5%
      of our outstanding common stock;

    - each of our executive officers named in the Summary Compensation Table;

    - each of our directors; and

    - all directors and executive officers as a group.

    Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. In computing the number of shares
beneficially owned by a person and the percentage ownership of that person,
shares of common stock subject to options or warrants held by that person that
are currently exercisable or will become exercisable within 60 days after
March 31, 2000, are deemed outstanding, while the shares are not deemed
outstanding for purposes of computing percentage ownership of any other person.
Unless otherwise indicated in the footnotes below, the persons and entities
named in the table have sole voting or investment power with respect to all
shares beneficially owned, subject to community property laws where applicable.

    The number and percentage of shares beneficially owned are based on the
aggregate of (i) 20,692,509 shares of common stock outstanding as of March 31,
2000, assuming conversion of all outstanding shares of preferred stock into
common stock and the issuance of 1,474,658 shares of common stock issuable upon
exercise of certain outstanding warrants prior to this offering, and
(ii)       shares of common stock issued in this offering.

                          DESCRIPTION OF CAPITAL STOCK

    The following description of our common stock and preferred stock and the
relevant provisions of our amended and restated certificate of incorporation and
amended and restated bylaws as will be in effect upon the closing of this
offering are summaries and are qualified by reference to these documents. Forms
have been filed with the Securities and Exchange Commission as exhibits to our
registration statement, of which this prospectus forms a part.

    Upon the closing of this offering, our authorized capital stock will consist
of 100,000,000 shares of common stock, par value $0.01 per share, and 10,000,000
shares of preferred stock, par value $0.01 per share.

COMMON STOCK

    As of March 31, 2000, there were 6,536,644 shares of common stock
outstanding held of record by 52 stockholders. Based upon the number of shares
outstanding as of that date and giving effect to the automatic conversion of all
previously outstanding preferred stock into shares of common stock, the assumed
exercise of all outstanding preferred stock warrants, the conversion into common
stock of the preferred stock issued upon the exercise of the warrants and the
sale of shares of common stock in this offering, assuming no exercise of the
underwriters' over-allotment option and no exercise of outstanding options after
March 31, 2000, there will be approximately       shares of common stock
outstanding at the closing of this offering.

    Holders of common stock are entitled to one vote per share on all matters
submitted to a vote of stockholders. Holders of common stock do not have
cumulative voting rights. Holders of common stock are entitled to receive
dividends as may be declared from time to time by the board of directors out of
funds legally available for the payment of dividends, subject to the preferences
that apply to any outstanding preferred stock. See "Dividend Policy." Upon a
liquidation, dissolution or winding up of Vastera, the holders of common stock
are entitled to share ratably in all assets remaining after payment of
liabilities and after giving effect to the liquidation preference of any
outstanding preferred stock. The common stock has no preemptive or conversion
rights and no additional subscription rights. There are no redemption or sinking
fund provisions applicable to the common stock. All outstanding shares of common
stock are fully paid and nonassessable. The shares issued in this offering will
be fully paid and nonassessable.

PREFERRED STOCK

    Our amended and restated certificate of incorporation authorizes the board
of directors, without stockholder action, to designate and issue from time to
time shares of preferred stock in one or more series. The board of directors may
designate the price, rights, preferences and privileges of the shares of each
series of preferred stock, which may be greater than the rights of the common
stock. It is not possible to state the actual effect of the issuance of any
shares of preferred stock upon the rights of holders of common stock until the
board of directors determines the specific rights of the preferred stock.
However, possible effects of issuing preferred stock with voting and conversion
rights include:

    - Restricting dividends on common stock;

    - Diluting the voting power of common stock;

    - Impairing the liquidation rights of the common stock;

    - Delaying or preventing a change of control of Vastera without stockholder
      action; and

    - Harming the market price of common stock.

                                       65
<PAGE>
    Upon the closing of this offering, no shares of our preferred stock will be
outstanding. We have no present plans to issue any shares of preferred stock.

</TABLE>

    After the closing of this offering, all of the warrants that have not
expired will become exercisable for that number of shares of common stock as is
indicated in the table.

OPTIONS

    In 1996, Vastera adopted the 1996 Stock Option Plan. Under the 1996 Plan,
6,750,000 shares of common stock are reserved for issuance to employees at the
discretion of our board of directors. At March 31, 2000, there were 175,398
shares of common stock available for future grant under the 1996 Plan. The
exercise price of all options outstanding under the 1996 Plan range from $1.00
to $6.67 with a weighted average exercise price of $4.77 and these options are
exercisable in the aggregate for 6,253,677 shares of common stock. Please see
"Management--Employee Benefit Plans" for a detailed description of the plan.

REGISTRATION RIGHTS

    Upon closing of this offering, the holders of 14,796,327 shares of common
stock, assuming the exercise of all outstanding preferred stock warrants and the
conversion into common stock of the preferred stock issued upon the exercise of
the warrants, will be entitled to demand registration rights requiring us to
register the sale of their shares under the Securities Act of 1933, under the
terms of an agreement between us and the holders of these shares. The holders of
40% or more of these shares are entitled to demand that Vastera register their
shares under the Securities Act, subject to various limitations. Vastera is not
required to effect more than two registrations pursuant to these demand
registration rights. In addition, these holders are entitled to piggyback
registration rights with respect to the registration of their shares under the
Securities Act, subject to various limitations. Further, at any time after
Vastera becomes eligible to file a registration statement on Form S-3, these
holders may require Vastera to file registration statements under the Securities
Act on Form S-3 with respect to their shares of common stock. These registration
rights are subject to certain conditions and limitations, among them the right
of the underwriters of an offering to limit the number of shares of common stock
held by these holders with registration rights to be included in a registration.
Vastera is generally required to bear all of the expenses of all of these
registrations, except underwriting discounts and selling commissions.
Registration of any of the shares of common stock held by these holders with
registration rights would result in shares becoming freely tradable without
restriction under the Securities Act immediately upon effectiveness of such
registration.

DELAWARE ANTI-TAKEOVER LAW AND PROVISIONS IN OUR CHARTER AND BYLAWS

    DELAWARE ANTI-TAKEOVER STATUTE.  We are subject to Section 203 of the
Delaware General Corporation Law. In general, these provisions prohibit a
Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years following the date that the
stockholder became an interested stockholder, unless the transaction in which
the person became an interested stockholder is approved in a manner presented in
Section 203 of the Delaware General Corporation Law. Generally, a "business
combination" is defined to include mergers, asset sales and other transactions
resulting in financial benefit to a stockholder. In general, an "interested
stockholder" is a person who, together with affiliates and associates, owns, or
within three years, did own, 15% or more of a corporation's voting stock.

    CERTIFICATE OF INCORPORATION.  Our amended and restated certificate of
incorporation provides that:

    - Our board of directors may issue, without further action by the
      stockholders, up to 10,000,000 shares of undesignated preferred stock;

    - Any action to be taken by our stockholders must be effected at a duly
      called annual or special meeting and not by a consent in writing;

    - Our board of directors shall be divided into three classes, with each
      class serving for a term of three years;

    - Vacancies on the board, including newly created directorships, can be
      filled by a majority of the directors then in office; and

    - Our directors may be removed only for cause.

    BYLAWS.  Our amended and restated bylaws provide that stockholders seeking
to bring business before an annual meeting of stockholders or to nominate
candidates for election as directors at an annual meeting of stockholders, must
provide timely notice to us in writing. To be timely, a stockholder's notice
must be received at our principal executive offices not less than 90 days nor
more than 120 days prior to the anniversary date of the immediately preceding
annual meeting of stockholders. In the event that the annual meeting is called
for a date that is not within 30 days before or 60 days after the anniversary
date, in order to be timely notice from the stockholder must be received:

    - not earlier than 120 days prior to the annual meeting of stockholders; and

    - not later than 90 days prior to the annual meeting of stockholders or the
      tenth day following the date on which notice of the annual meeting was
      made public.

    In the case of a special meeting of stockholders called for the purpose of
electing directors, notice by the stockholder, in order to be timely, must be
received:

    - not earlier than 120 days prior to the special meeting; and

    - not later than 90 days prior to the special meeting or the close of
      business on the tenth day following the day on which public disclosure of
      the date of the special meeting was made.

    Our amended and restated bylaws also specify requirements as to the form and
content of a stockholder's notice. These provisions may preclude stockholders
from bringing matters before an annual or special meeting of stockholders, from
making nominations for directors at an annual or special meeting of stockholders
or from making nominations for directors at an annual or special meeting of
stockholders. In addition, a two-thirds supermajority vote of stockholders will
be required to amend our amended and restated bylaws.

                                       67
<PAGE>
    The provisions in our amended and restated certificate of incorporation and
our amended and restated bylaws are intended to enhance the likelihood of
continuity and stability in the composition of the board of directors and in the
policies formulated by the board of directors and to discourage certain types of
transactions that may involve an actual or threatened change of control of
Vastera. These provisions also are designed to reduce our vulnerability to an
unsolicited proposal for a takeover of Vastera that does not contemplate the
acquisition of all of its outstanding shares or an unsolicited proposal for the
restructuring or sale of all or parts of Vastera. These provisions, however,
could discourage potential acquisition proposals and could delay or prevent a
change in control of Vastera. They may also have the effect of preventing
changes in our management.

                        SHARES ELIGIBLE FOR FUTURE SALE

    Sales of substantial amounts of common stock in the public market following
the offering could adversely affect the market price of the common stock and
adversely affect our ability to raise capital at a time and on terms favorable
to us.

    Of the              shares to be outstanding after the offering,
             shares of common stock will be freely tradable unless they are
purchased by our "affiliates," as that term is defined in Rule 144 under the
Securities Act. The remaining shares, assuming no exercise of outstanding
options and warrants, will be eligible for sale in the public market as follows:

    RULE 144.  In general, under Rule 144 as currently in effect, a person who
has beneficially owned shares for at least one year, including an "affiliate,"
as that term is defined in the Securities Act, is entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of:

    - one percent of the then outstanding shares of our common stock
      (approximately              shares immediately following the offering), or

    - the average weekly trading volume during the four calendar weeks preceding
      filing of notice of such sale.

    Sales under Rule 144 are also subject to certain manner of sale provisions,
notice requirements and the availability of current public information about us.
A shareholder who is deemed not to have been an "affiliate" of ours at any time
during the 90 days preceding a sale, and who has beneficially owned restricted
shares for at least two years, would be entitled to sell such shares under
Rule 144(k) without regard to the volume, limitations, manner of sale provisions
or public information requirements. For purposes of Rule 144, an "affiliate" of
an issuer is a person that, directly or indirectly through one or more
intermediaries, controls, or is controlled by or is under common control with,
such issuer. All of our affiliates have agreed to further restrict their shares
by entering into lock-up arrangements discussed above.

    RULE 701.  In general, under Rule 701 of the Securities Act as currently in
effect, each of our directors, officers, employees, consultants or advisors who
purchased shares from us before the date of this prospectus in connection with a
compensatory stock plan or other written compensatory agreement is eligible to
resell such shares 90 days after the effective date of this offering in reliance
on Rule 144, but without compliance with certain restrictions, including the
holding period, contained in Rule 144.

    STOCK PLANS.  As of March 31, 2000, options to purchase 6,253,677 shares of
our common stock were outstanding under our 1996 Stock Option Plan. After this
offering, we intend to file registration statements on Form S-8 under the
Securities Act of 1933 covering shares of common stock reserved for issuance
under our 1996 Plan, our 2000 Stock Option/Stock Issuance Plan and our 2000
Employee Stock Purchase Plan. Based on the number of options outstanding and
shares

                                       69
<PAGE>
reserved for issuance under our 1996 Plan, our 2000 Plan and our 2000 Stock
Purchase Plan, the registration statements on Form S-8 will cover
shares. The Form S-8 registration statements will become effective immediately
upon filing, whereupon, subject to the satisfaction of applicable exercisability
periods, Rule 144 volume limitations applicable to affiliates and the lock-up
agreements with the underwriters referred to above, shares of common stock to be
issued upon exercise of outstanding options granted pursuant to our 1996 Plan,
our 2000 Plan and our 2000 Stock Purchase Plan (to the extent that such shares
were not held by affiliates) will be available for immediate resale in the
public market.

    LOCK-UP AGREEMENT.  Each of our officers and directors, and substantially
all of our stockholders and holders of options and warrants to purchase our
stock have agreed not to sell or otherwise dispose of any shares of common stock
for a period of 180 days after the date of this prospectus without the prior
written consent of Deutsche Bank Securities Inc. Transfers or dispositions can
be made during the lock-up period in the case of gifts or for estate planning
purposes where the donee signs a lock-up agreement. Upon the expiration of these
lock-up agreements, additional shares will be available for sale in the public
market.

    REGISTRATION RIGHTS.  After this offering, the holders of 14,796,327 shares
of our common stock will be entitled to certain rights with respect to the
registration of their shares under the Securities Act. See "Description of
Capital Stock--Registration Rights." After any such registration of these
shares, such shares will be freely tradeable without restriction under the
Securities Act. These sales could cause the market price of our common stock to
decline.

                                  UNDERWRITING

    Subject to the terms and conditions of the underwriting agreement, the
underwriters named below, through their representatives Deutsche Bank Securities
Inc., Chase Securities Inc. and Banc of America Securities LLC, have severally
agreed to purchase from Vastera the following respective number of shares of
common stock at a public offering price less the underwriting discounts and
commissions set forth on the cover page of this prospectus:

Banc of America Securities LLC..............................
                                                                 ---------
    Total Underwriters (  ).................................
                                                                 =========
</TABLE>

    The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares of common stock offered hereby are subject
to certain conditions precedent and that the underwriters will purchase all
shares of the common stock offered hereby, other than those covered by the
over-allotment option described below, if any of these shares are purchased.

    The underwriters propose to offer the shares of common stock to the public
at the public offering price set forth on the cover of this prospectus and to
dealers at a price that represents a concession not in excess of $   per share
under the public offering price. The underwriters may allow, and these dealers
may re-allow, a concession of not more than $   per share to other dealers.
After the initial public offering, representatives of the underwriters may
change the offering price and other selling terms.

    We have granted to the underwriters an option, exercisable not later than 30
days after the date of this prospectus, to purchase up to       additional
shares of common stock at the public offering price less the underwriting
discounts and commissions set forth on the cover page of this prospectus. The
underwriters may exercise this option only to cover over-allotments made in
connection with the sale of the common stock offered hereby. To the extent that
the underwriters exercise this option, each of the underwriters will become
obligated, subject to conditions, to purchase approximately the same percentage
of additional shares of common stock as the number of shares of common stock to
be purchased by it in the above table bears to the total number of shares of
common stock offered hereby. We will be obligated, pursuant to the option, to
sell these additional shares of common stock to the underwriters to the extent
the option is exercised. If any additional shares of common stock are purchased,
the underwriters will offer the additional shares on the same terms as those on
which the       shares are being offered.

    The underwriting fee is equal to the public offering price per share of
common stock less the amount paid by the underwriters to us per share of common
stock. The underwriting fee is   % of the initial public offering price. We have
agreed to pay the underwriters the following fees, assuming either no exercise
or full exercise by the underwriters of the underwriters' over-allotment option:

    In addition, we estimate that our share of the total expenses of this
offering, excluding underwriting discounts and commissions, will be
approximately $          .

                                       71
<PAGE>
    We have agreed to indemnify the underwriters against some specified types of
liabilities, including liabilities under the Securities Act, and to contribute
to payments the underwriters may be required to make in respect of any of these
liabilities.

    Each of our officers and directors, and substantially all of our
stockholders and holders of options and warrants to purchase our stock, have
agreed not to offer, sell, contract to sell or otherwise dispose of, or enter
into any transaction that is designed to, or could be expected to, result in the
disposition of any shares of our common stock or other securities convertible
into or exchangeable or exercisable for shares of our common stock or
derivatives of our common stock owned by these persons prior to this offering or
common stock issuable upon exercise of options or warrants held by these persons
for a period of 180 days after the effective date of the registration statement
of which this prospectus is a part without the prior written consent of Deutsche
Bank Securities Inc. This consent may be given at any time without public
notice. Transfers or dispositions can be made during the lock-up period in the
case of gifts or for estate planning purposes where the donee signs a lock-up
agreement. We have entered into a similar agreement with the representatives of
the underwriters, except that without such consent we may grant options and sell
shares pursuant to our 1996 Stock Option Plan, our 2000 Stock Option/Stock
Issuance Plan and our 2000 Employee Stock Purchase Plan, and may issue shares of
our common stock in connection with a strategic partnering transaction or in
exchange for all or substantially all of the equity or assets of a company in
connection with a merger or acquisition. There are no agreements between the
representatives and any of our stockholders or affiliates releasing them from
these lock-up agreements prior to the expiration of the 180-day period.

    The representatives of the underwriters have advised us that the
underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.

    In order to facilitate the offering of our common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
market price of our common stock. Specifically, the underwriters may over-allot
shares of our common stock in connection with this offering, thus creating a
short position in our common stock for their own account. A short position
results when an underwriter sells more shares of common stock than that
underwriter is committed to purchase. Additionally, to cover these
over-allotments or to stabilize the market price of our common stock, the
underwriters may bid for, and purchase, shares of our common stock in the open
market. Finally, the representatives, on behalf of the underwriters, may also
reclaim selling concessions allowed to an underwriter or dealer if the
underwriting syndicate repurchases shares distributed by that underwriter or
dealer. Any of these activities may maintain the market price of our common
stock at a level above that which might otherwise prevail in the open market.
These transactions may be effected on the Nasdaq National Market or otherwise.
The underwriters are not required to engage in these activities and, if
commenced, may end any of these activities at any time.

    At our request, the underwriters have reserved for sale, at the initial
public offering price, up to       shares for our vendors, employees, family
members of employees, customers and other third parties. Pursuant to a prior
agreement, the holders of shares of our Series C convertible preferred stock are
entitled to purchase in this offering $3.0 million of common stock. The number
of shares of our common stock available for sale to the general public will be
reduced to the extent these reserved shares are purchased. Any reserved shares
that are not purchased by these persons will be offered by the underwriters to
the general public on the same basis as the other shares in this offering.

    In February 2000, we sold shares of our Series E convertible preferred stock
in a private placement at a price of $10.83 per share. In this private
placement, BT Investment Partners, Inc., an affiliate of Deutsche Bank
Securities Inc., purchased 46,168 shares of Series E convertible preferred

                                       72
<PAGE>
stock for an aggregate purchase price of $499,999.44. Additionally, Hambrecht &
Quist California, H&Q Employee Venture Fund 2000, L.P., Access Technology
Partners, L.P. and Access Technology Partners Brokers Fund, L.P., affiliates of
Chase Securities Inc., purchased 6,186 shares, 2,308 shares, 36,935 shares and
739 shares, respectively, of Series E convertible preferred stock for an
aggregate purchase price of $499,999.44.

    In November 1998 we issued a warrant for 30,763 shares of our Series D
convertible preferred stock in a private placement to Banc of America Securities
LLC (formerly, NationsBanc Montgomery Securities L.L.C.). Banc of America
Securities LLC acted as placement agent in this private placement.

PRICING OF THIS OFFERING

    Prior to this offering, there has been no public market for our common
stock. Consequently, the initial public offering price for our common stock has
been determined by negotiation among us and the representatives of the
underwriters. Among the primary factors considered in determining the public
offering price were:

    - prevailing market conditions;

    - our results of operations in recent periods;

    - the present stage of our development;

    - the market capitalization and stage of development of other companies that
      we and the representatives of the underwriters believe to be comparable to
      our business; and

    - estimates of our business potential.

                                    EXPERTS

    The financial statements and schedules included in this prospectus and
elsewhere in the registration statement have been audited by Arthur Andersen
LLP, independent public accountants, as indicated in their reports with respect
thereto, and are included herein in reliance upon the authority of said firm as
experts in giving said reports.

                                 OTHER MATTERS

    On March 26, 1999, our board of directors dismissed PricewaterhouseCoopers
LLP as its independent accountants. From our inception through March 26, 1999,
the former auditors did not disagree with us on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure which disagreements, if not resolved to their satisfaction, would have
caused them to make reference thereto in their report on the financial
statements for such years. During the period from our inception to the date of
their dismissal, there have been no reportable events as defined in
Regulation S-K Item 304(a)(1)(iv). In response to our request,
PricewaterhouseCoopers LLP has furnished us with a letter addressed to the
Securities and Exchange Commission stating whether or not PricewaterhouseCoopers
LLP agrees with the above statements. We have filed a copy of such letter dated
April 5, 2000 as Exhibit 16 to the registration statement of which this
Prospectus is a part.

    In March 26, 1999, our board of directors retained Arthur Andersen LLP as
our independent public accountants. Prior to retaining Arthur Andersen LLP, we
had not consulted with Arthur Andersen LLP on any accounting, auditing or
reporting matter.

                             ADDITIONAL INFORMATION

    We have filed with the Securities and Exchange Commission, or SEC, a
registration statement on Form S-1 with respect to the common stock offered
hereby. This prospectus, which constitutes a part of the registration statement,

and other information with the SEC. Such periodic reports, proxy statements and
other information will be available for inspection and copying at the SEC's

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Vastera, Inc.:

    We have audited the accompanying consolidated balance sheets of
Vastera, Inc. (a Delaware corporation) and its subsidiary as of December 31,
1998 and 1999, and the related consolidated statements of operations and changes
in stockholders' equity (deficit) and cash flows for each of the three years in
the period ended December 31, 1999. 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 auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Vastera, Inc. and its
subsidiary as of December 31, 1998 and 1999, and the results of their operations
and their cash flows for each of the three years in the period ended
December 31, 1999 in conformity with accounting principles generally accepted in
the United States.

    As explained in Note 2 to the consolidated financial statements, the Company
has given retroactive effect to the change in accounting for software license
revenues.

1. THE COMPANY:

NATURE OF THE BUSINESS

    Vastera, Inc. ("Vastera" or the "Company") is a provider of solutions for
global trade management. The Company's offerings include a library of global
trade content, web-based business-to-business, or B2B, solutions and management
consulting and solution services. Global trade involves the physical movement of
goods across borders, the management of information required to enable global

required to enable global trade and enhance collaboration across a client's
global trade network.

    The Company's operations are subject to certain risks and uncertainties,
including among others, uncertainties relating to product development, rapidly
changing technology, current and potential competitors with greater financial,
technological, production, and marketing resources, dependence on key management
personnel, limited protection of intellectual property and proprietary rights,
uncertainty of future profitability and possible fluctuations in financial
results.

ACQUISITIONS

    On January 31, 1999, the Company acquired Deltac Limited ("Deltac"), located
in Wales, United Kingdom, a privately owned company and provider of

five years.

    On June 1, 1999, the Company acquired Quantum Consulting Associates, Inc.
("Quantum"), located in Denver, Colorado, a privately owned international trade
consulting company. The purchase method of accounting has been applied to this
acquisition, and accordingly, the results of operations of Quantum are included
in the Company's operations from the date of acquisition.

    The shareholders of Quantum received approximately $439,000 in cash and
567,000 shares of common stock of Vastera, valued at approximately $1,511,000,

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

PRINCIPLES OF CONSOLIDATION AND BASIS OF PRESENTATION

    The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary, Vastera, Ltd., from the date of acquisition.
All significant intercompany balances and transactions have been eliminated in
consolidation.

UNAUDITED PRO FORMA BALANCE SHEET INFORMATION

    The unaudited pro forma balance sheet information is being presented to show
the mandatory conversion of all shares of redeemable convertible preferred stock
outstanding at December 31, 1999 into shares of common stock upon a qualified
initial public offering. All of the Company's preferred stock will automatically
convert into shares of common stock if the initial public offering is
consummated under terms presently anticipated.

USE OF ESTIMATES

    The preparation of the consolidated financial statements in conformity with
accounting principles generally accepted in the United States requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosures of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

REVENUE RECOGNITION

    The Company's revenues consist of subscription/transaction revenues and
services revenues.

    Revenues classified as subscription/transaction revenues are derived from
subscription/ transaction arrangements and sales of perpetual software licenses
and maintenance services. Revenues from software licenses, maintenance

product (three years) or, if stated, the contract term. Maintenance contracts
include the right to unspecified enhancements on a when-and-if available basis,
ongoing support, and content update services. Transaction fees are recognized as
revenue when earned based on the usage of the Company's product. Revenue
recognition begins upon the execution of a software license and maintenance
agreement and delivery of the product.

    Services revenues are derived from implementation, management consulting and
training services. Services are performed on a time and materials basis or under
fixed price arrangements and are recognized as the services are performed or
using percentage of completion.

ACCOUNTING CHANGE

    In 1999, the Company changed its method of recognizing revenue under
software license arrangements. The Company has accounted for software licenses
as a subscription arrangement over the term of the contract or the estimated
economic life of the product (three years) if the contract term is not
specified. Prior to the change, license fees were recognized upon delivery of
the software. The new method of accounting for software license fees was adopted
since the content updates provided under maintenance arrangements are essential
to the continued functionality of the software product. The financial statements
of prior years have been restated to apply the new method retroactively.

    The direct effect of the change in accounting principle on net losses and
pro forma loss per share for the years ending December 31, 1997, 1998, and 1999
is as follows:

SOFTWARE DEVELOPMENT COSTS

    In accordance with Statement of Financial Accounting Standards ("SFAS")
No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased, or
Otherwise Marketed," software development costs are expensed as incurred until
technological feasibility has been established, at which time such costs are
capitalized until the product is available for general release to customers. To
date, the establishment of technological feasibility of the Company's products
and general release of such software have substantially coincided. As a result,
software development costs qualifying for capitalization have been
insignificant, and therefore, the Company has not capitalized any software
development costs.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
CASH AND CASH EQUIVALENTS

    The Company considers all highly liquid investments purchased with a
maturity of three months or less to be cash equivalents.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    SFAS No. 107, "Disclosures About Fair Value of Financial Instruments,"
requires disclosures of fair value information about financial instruments,
whether or not recognized in the balance sheet, for which it is practicable to
estimate that value. SFAS No. 107 excludes certain financial instruments and all
nonfinancial instruments from these disclosure requirements. Accordingly, the
aggregate fair value amounts presented do not represent the underlying value of
the Company. The carrying amounts reported in the consolidated balance sheets
approximate the fair value for cash and cash equivalents, investments, accounts
receivable, accounts payable, and capital lease obligations.

INVESTMENTS

    The Company accounts for investments in accordance with SFAS No. 115,
"Accounting for Certain Investments in Debt and Equity Securities." In 1998 and
1999, the Company used its existing cash on hand to invest in certain debt
securities. The Company considers all of its investments as of December 31, 1998
and 1999, to be available-for-sale.

    As of December 31, 1998, there were no material unrealized gains and losses.
As of December 31, 1999, the Company recognized approximately $41,000 of net
unrealized losses on investments in debt securities as a component of
stockholders' equity.

CONCENTRATIONS OF CREDIT RISK

    Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash equivalents and accounts receivable.
The Company limits the amount of investment exposure in any one financial
instrument and does not have any foreign currency investments. The Company sells
products and services to customers across several industries throughout the
world without requiring collateral. However, the Company routinely assesses the
financial strength of its customers and maintains allowances for anticipated
losses.

    There were no customers that represented 10 percent or more of accounts
receivable as of December 31, 1998. As of December 31, 1999, one customer
accounted for 16 percent of total accounts receivable.

DEPRECIATION AND AMORTIZATION

    Depreciation is computed using the straight-line method over the estimated
useful lives of the assets, generally three to five years. Assets acquired under
capital leases and leasehold improvements are amortized using the straight-line
method over the shorter of the estimated useful lives of the assets or the terms
of the leases. For the years ended December 31, 1997, 1998, and 1999,
depreciation and amortization expense was approximately $407,000, $637,000, and
$1,625,000, respectively.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
LONG-LIVED ASSETS

    The Company reviews its long-lived assets, including property and equipment
and goodwill for impairment whenever events or changes in circumstances indicate
that the carrying amount of the assets may not be recoverable. To determine
recoverability of its long-lived assets, the Company evaluates the future,
undiscounted, net cash flows compared to the carrying amount of the assets.

INCOME TAXES

    Deferred taxes are provided utilizing the liability method as prescribed by
SFAS No. 109, "Accounting for Income Taxes," whereby deferred tax assets are
recognized for deductible temporary differences and operating loss and tax
credit carryforwards and deferred tax liabilities are recognized for taxable
temporary differences. Temporary differences are the differences between the
reported amounts of assets and liabilities and their tax bases. Deferred tax
assets and liabilities are adjusted for the effects of changes in tax laws and
rates on the date of enactment. Deferred tax assets are reduced by a valuation
allowance when, in the opinion of management, it is more likely than not that
some portion or all of the deferred tax assets will not be realized.

PRO FORMA LOSS PER COMMON SHARE

    Pro forma loss per common share is computed using the pro forma
weighted-average number of common shares outstanding for the year ended
December 31, 1999. Pro forma weighted-average common shares include the assumed
conversion of all outstanding convertible preferred stock into common stock.
Since the conversion of the preferred stock has a significant effect on the loss
per share calculation, the historical loss per share has not been presented.

    Basic earnings per share includes no dilution and is computed by dividing
net loss available to common stockholders by the weighted average number of
common shares outstanding for the period. Diluted earnings per share includes
the potential dilution that could occur if securities or other contracts to
issue common stock were exercised or converted into common stock. As of
December 31, 1999, options to purchase approximately 4,727,000 shares of common
stock and warrants to purchase 1,248,000 shares of redeemable convertible
preferred stock were outstanding. Due to the anti-dilutive nature of the options
and warrants there is no effect on the calculation of weighted-average shares
for diluted earnings per share. As a result, the basic and diluted loss per
share amounts are identical.

FOREIGN CURRENCY TRANSLATION

    The Company uses the U.S. dollar as its functional currency in all foreign
locations. Assets and liabilities are translated into U. S. dollars as of the
balance sheet date. Revenues, expenses, gains, and losses are translated at the
average exchange rates in effect during each period. There were no material
gains or losses resulting from translation or foreign currency exchange
transactions during 1999.

COMPREHENSIVE INCOME

    As of December 31, 1999, accumulated other comprehensive income includes
unrealized gains and losses on investments. As of December 31, 1997 and 1998,
the Company did not have any

    As of December 31, 1999, goodwill of approximately $2,079,000 relates to the
Company's 1999 acquisitions. Accumulated amortization as of December 31, 1999,
was approximately $313,000.

4. LONG-TERM DEBT:

LINE OF CREDIT

    In June 1997, the Company received a $1,000,000 convertible bridge loan (the
"Bridge Loan") from an equity investor (the "Investor"). The loan had an
interest rate of 10 percent. In August 1997, the $1,000,000 principal bridge
loan was converted into approximately 270,000 shares of Series C redeemable
convertible preferred stock.

    On April 28, 1998, the Company obtained a line of credit from a bank for
$2,500,000 with a $500,000 sublimit for equipment purchases, subject to
borrowing base restrictions. During 1998 the equipment line of credit was
increased to $1,000,000. The line bears interest at prime plus 1.25 percent. The
line of credit is collateralized by the first lien on all corporate assets,
including intangible assets. As of December 31, 1998, there were no borrowings
outstanding under this line of credit. The Company terminated this line of
credit in March 1999.

    In March 1999, the Company negotiated a $2,500,000 secured revolving credit
facility and a $1,500,000 equipment line of credit with a different bank. The
line bears interest at the prime rate plus .75 percent for the secured revolving
credit facility and the prime rate plus .85 percent for the equipment line of
credit. In September 1999, the equipment line was increased to $3,000,000. As of
December 31, 1999, the outstanding balance under the equipment line was
approximately $1,723,000 and there were no amounts outstanding under the
revolving line of credit. The revolving line of credit expires on September 5,
2000. Amounts borrowed under the equipment line are initially subject to
interest-only payments and after the interest-only period will be repayable over
three years.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

4. LONG-TERM DEBT: (CONTINUED)
    The terms of the line of credit require the Company to comply with certain
financial covenants. As of December 31, 1999, the Company was in violation of
these covenants. On February 3, 2000, the bank granted the Company a waiver of
past covenant violations and waived its right to call the line of credit for
these covenant violations.

    On March 3, 2000, the Company amended the existing financial covenants and
increased the equipment line of credit to $4,800,000. The most restrictive of
the amended financial covenants is that the Company's operating losses will not
exceed $5,000,000 for the second, third, and fourth fiscal quarters of 2000 and
$2,000,000 in any quarter thereafter, and, beginning in the first quarter of
2002, the Company is not permitted to have two consecutive quarters with
operating losses. Other financial covenants require that the Company maintain a
quick ratio, as defined, of at least 1.25 at all times and that the Company's
maintain a minimum tangible net worth, as defined, as follows (in thousands):

CAPITAL LEASE OBLIGATIONS

    The Company leases office equipment under various noncancelable capital
leases. The Company obtained an equipment leasing arrangement in the aggregate
of $1,400,000 in 1997 and an additional $250,000 in 1998 from a lending
institution (the "Lender"). Amounts borrowed from the equipment leasing
arrangement are due over 36- to 48-month repayment periods and are
collateralized by the Company's software product.

    In connection with the capital lease arrangement from the Lender and the
Bridge Loan from the Investor during 1997, the Company issued the Lender and the
Investor warrants to purchase an aggregate of appoximately 7,000, 5,000, and
18,000 shares of Series A preferred stock, Series B preferred stock, and
Series C preferred stock, respectively. The fair value of these warrants was
immaterial to the consolidated financial statements.

    Property and equipment includes approximately $1,914,000 and $1,798,000 of
equipment under capital lease arrangements at December 31, 1998 and 1999,
respectively. Related accumulated depreciation was approximately $904,000 and
$1,437,000 at December 31, 1998 and 1999, respectively.

includes the $1,000,000 Bridge Loan (see Note 4) that was converted into
approximately 270,000 shares of Series C. On September 3, 1997, the Company
issued approximately 81,000 shares of Series C and warrants to purchase
approximately 14,000 shares of Series C-1 to new investors for total
consideration of $300,000. The Series C-1 warrants were valued at approximately
$477,000.

    On February 12, 1998, and May 28, 1998, pursuant to stock purchase
agreements with various new investors, the Company issued approximately 540,000
and 68,000 shares of Series C and warrants to purchase approximately 95,000 and
11,000 shares of Series C-1 for total consideration of $2,000,000 and $250,000,
respectively. The warrants were valued at approximately $171,000.

    On November 24, 1998, pursuant to a stock purchase agreement with various
investors, the Company issued approximately 2,461,000 shares of Series D
redeemable convertible preferred stock ("Series D") and warrants to purchase
approximately 246,000 shares of Series D-1 redeemable convertible preferred
stock ("Series D-1") for total consideration of $12,000,000. The warrants to
purchase shares of Series D-1 were valued at approximately $197,000. The Company
paid approximately $832,000 in legal and broker fees related to these issuances,
which has been reflected as a reduction in the proceeds from the sale of
Series D. In connection with the sale of Series D, the Company issued warrants
to purchase approximately 31,000 shares of Series D to a securities company as a
fee related to the transaction. The fair value of these warrants was
approximately $40,000.

    On February 26, 1999, pursuant to a stock purchase agreement with a new
investor, the Company issued approximately 513,000 shares of Series D for total
consideration of approximately $2,500,000. On September 1, 1999, the Company
issued this new investor warrants to purchase approximately 386,000 shares of
Series D-1 in connection with the signing of a subscription agreement. The
warrants issued to this customer were valued at approximately $231,000 and are
accounted for as a discount to revenue over the term of the subscription
agreement. On February 22, 2000, the investor notified the Company that they
will terminate the subscription agreement, effective September 1, 2000.
Accordingly, the remaining sales discount will be amortized through
September 1, 2000.

    On February 4, 2000 and February 29, 2000, pursuant to a stock purchase
agreement with new and existing investors, the Company issued approximately
1,570,000 shares of Series E redeemable convertible preferred stock ("Series E")
for approximately $16,999,000. The Company expects to record a beneficial
conversion feature of approximately $8.1 million in the first quarter of 2000 to
reflect the difference between the underlying convertible price per share of
common stock and the estimated fair market value of the common stock on the date
of issuance. In connection with the sale of Series E shares, the Company
increased the common shares authorized to 40,000,000 shares.

    In connection with the various stock purchase agreements, the Company and
the various investors entered into a stockholders agreement. The stockholders
agreement, among other things, prescribes certain limitations on the transfer of
stock, grants the various investors certain rights of first refusal and co-sale
rights with respect to the sales of stock, and provides for voting rights with
respect to the election of the directors under certain circumstances.

    Holders of Series A, Series B, Series C, Series C-1, Series D, Series D-1,
and Series E are entitled to cumulative dividends at the rate per annum of
$0.40, $0.53, $0.30, $0.39, $0.39, $0.52 and $0.86 per share, respectively.

WARRANTS

    In connection with the sales of the Series A, Series C, and Series D, the
Company issued warrants to investors to purchase an aggregate of approximately
150,000, 405,000, and 632,000 shares of Series B, Series C-1 and Series D-1,
respectively, at exercise prices of $6.65, $4.92, and $6.49 per share. In
connection with the sale of Series D, the Company also issued warrants to
purchase approximately 31,000 shares of Series D at $5.61 per share. The
warrants are immediately exercisable and may be exercised only in their
entirety.

    The warrants to purchase Series B will expire on the earlier of
(i) July 31, 2001, or upon ten days prior written notice by the Company to the
warrant holder, (ii) on the date of the closing of an initial public offering
where the price is at least $5.00 per share and the net proceeds to the Company
are at least $15 million, or (iii) 30 days after written notice from the Company
informing the warrant holder that the Company has completed a 12-month operating
period during which gross revenues equal or exceed $20 million.

    The warrants to purchase Series C-1 and Series D will expire on the earlier
of (i) the fifth anniversary of the issuance date, (ii) on the date of the
closing of an initial public offering where the price per share is at least

the warrant holder that the Company has completed a 12-month operating period
during which gross revenues equal or exceed $30 million.

    The warrants to purchase 246,000 shares of Series D-1 will expire on
May 24, 2000, and warrants to purchase 386,000 shares of Series D-1 will expire
on March 1, 2001.

CONVERSION

    Each share of redeemable convertible preferred stock is convertible into
common stock at the option of the holder and converts automatically at the
consummation date of a qualified initial public offering. As of December 31,
1999, each share of Series A and Series B was convertible into three shares of
common stock, and each share of Series C, Series C-1, Series D, Series D-1, and
Series E was convertible into one and a half shares of common stock. The
conversion rates are subject to adjustments for events such as stock splits,
stock dividends, or issuances of stock.

LIQUIDATION PREFERENCE

    In the event of liquidation, dissolution, or winding up of the Company, the
holders of Series A, Series B, Series C, Series C-1, Series D, Series D-1, and
Series E are entitled to a liquidation preference over the holders of the
Company's common stock. The liquidation preference equals the original issuance
price plus any unpaid dividends. No dividends have been declared or paid through
December 31, 1999.

    Holders of Series D, Series D-1, and Series E shares have partial
liquidation preferences, which are preferential to other shares of redeemable
convertible preferred stock. This partial preference is limited to accrued
dividends of $.79, $1.86, and $4.75 per share, subject to stock dividends and
stock splits, for Series D, Series D-1, and Series E, respectively.

    If the holders of shares of redeemable convertible preferred stock would be
entitled to receive an amount per share greater than two times the original
issuance price for each share of redeemable convertible preferred stock, subject
to adjustment in the event of any stock dividend or stock split, then the
holders of the shares of redeemable convertible preferred stock shall be
entitled to share only with the holders of the common stock on an
as-if-converted basis, and such holders of shares of redeemable convertible
preferred stock shall not be entitled to receive the liquidation preference.

REDEMPTION

    At the option of the holders of a majority of the aggregate number of shares
of each series of redeemable convertible preferred stock, the Company shall
redeem, commencing on August 7, 2002, and continuing on the immediately
succeeding two anniversaries thereof in three installments, taking into effect
the prior redemptions, the number of shares of that series held by the holders.
In the event that the holders of a majority of the aggregate number of shares of
the particular series do not elect to exercise their redemption rights, they may
elect to exercise such rights at a subsequent anniversary, subject to certain
defined limitations. The redemption price shall be the greater of the fair
market value of such shares or the liquidation preference. The Company records
periodic accretion under the effective interest method on the redeemable
convertible preferred

As of December 31, 1999, the redemption price is calculated based on the fair
market value of such shares as it is greater than the liquidation preference.

6. STOCKHOLDERS' EQUITY (DEFICIT):

STOCK SPLITS AND INCREASE IN AUTHORIZED SHARES

    On February 10, 1997, the Company declared a two-for-one stock split
effected in the form of a stock dividend for each common share. On April 4,
2000, the board of directors voted to approve a three-for-two stock split which
will be effected in the form of a stock dividend for each common share just
prior to the closing of the offering. The Board also approved an increase in
authorized shares of common stock from 23,250,000 to 100,000,000 which will be
effected prior to the closing of the offering. All share information has been
adjusted retroactively in these consolidated financial statements for all
periods presented.

COMMON STOCK

    Dividends may be declared and paid on common stock shares at the discretion
of the Company's Board of Directors and are subject to any preferential dividend
rights of any current outstanding Preferred Stock. No common stock dividends
have been declared or paid as of December 31, 1999.

    Subject to the voting rights of the holders of preferred stock shares, the
holder of each share of common stock is entitled to one vote on all matters
voted on by the stockholders of the Company.

STOCK OPTION PLAN

    On July 26, 1996, the Company adopted a Stock Option Plan (the "Plan") in
order to provide an incentive to eligible employees, consultants, and officers
of the Company. The Plan provides for grants of incentive stock options,
nonqualified stock options, and stock awards to employees, directors,
consultants and advisors. Under the Plan, 6,000,000 shares of common stock are
reserved and available for distribution at December 31, 1999. For incentive
stock options, the exercise price may not be less than the determined fair
market value at the date of grant. For nonqualified stock options, the exercise
price shall be at least equal to 85 percent of the fair market value of the
shares at the date of grant. Stock options granted under the Plan vest over a
four to six-year period and expire ten years after the grant date. Approximately
1,057,000 options are available for future grant as of December 31, 1999.

has been included in the consolidated financial statements because the exercise
prices were equal to the fair market value at the time the options were granted.
For the year ended December 31, 1999, the Company recognized compensation
expense of approximately $378,000.

    Stock option compensation expense, which has been separately identified in

deferred compensation of approximately $11,756,000 in the first quarter of 2000
related to these option grants, based on the deemed intrinsic value of the stock
option at the date of grant. The deferred compensation will be recognized over
the vesting period of the related options.

    On April 4, 2000 the Company adopted a 2000 Stock Option/Stock Issuance Plan
(the "2000 Plan") to replace the 1996 Stock Option Plan, effective upon the
completion of the offering. 10,000,000 shares of common stock have been

shares of common stock have been authorized for issuance under the ESP Plan.
Employees who work more than 20 hours a week for more than five calendar months
per year are eligible to participate in the ESP Plan. A participant may
contribute up to 15 percent of their salary. Shares of common stock will be
purchased semi-annually at a price per share equal to the lower of 85 percent of

allowance of the same amount. The tax provision differed from the expected tax
benefit, computed by applying the U.S. Federal statutory rate of 35% to the loss
before income taxes, principally due to the effect of increases in the valuation
allowance.

    Deferred tax assets are comprised of the following (in thousands):

    Management believes that, based on a number of factors, the available
objective evidence creates sufficient uncertainty regarding the realizability of
the deferred tax assets such that a full valuation allowance is required. Such
factors include the lack of a significant history of material profits, recent
increases in expense levels to support the Company's growth, the fact that the
market in which the Company competes is intensely competitive and characterized
by rapidly changing technology, the materiality of revenues from indirect
channel partners, the lack of

carryback capacity to realize deferred tax assets, and the uncertainty regarding
market acceptance of new versions of the Company's software.

    As of December 31, 1998 and 1999, the Company had approximately
$12.4 million and $19.5 million, respectively, of federal net operating losses,
which will be carried forward to offset future taxable income, subject to
ownership change limitations. As of December 31, 1998 and 1999, the Company had
research and development tax credit carryforwards of approximately $379,000 and
$590,000, respectively. The net operating loss and research and development tax
credit carryforwards will begin to expire in 2011.

was approximately $281,000, $322,000, and $860,000, respectively.

LITIGATION

    On April 6, 1998, the Company settled an employment-related lawsuit with a
former employee by issuing 120,000 shares of common stock valued at $120,000.
The estimated settlement cost, including legal costs associated with the case,
was accrued as of December 31, 1997.

    The Company is periodically a party to disputes arising from normal business
activities. In the opinion of management, resolution of these matters will not
have a material adverse effect upon the financial position or future operating
results of the Company.

    The Company sponsors a 401(k) profit sharing plan to provide retirement and
incidental benefits for its employees (the "401(k) Plan"). As allowed under

tax-deferred salary deductions for eligible employees. The Company may make
matching contributions to the 401(k) Plan. The Company contributed

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 145 of the Delaware General Corporation Law (the "DGCL") provides,
in effect, that any person made a party to any action by reason of the fact that
he is or was a director, officer, employee or agent of Vastera may and, in
certain cases, must be indemnified by Vastera against, in the case of a
non-derivative action, judgments, fines, amounts paid in settlement and
reasonable expenses (including attorneys' fees) incurred by him as a result of
such action, and in the case of a derivative action, against expenses (including
attorneys' fees), if in either type of action he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
Vastera. This indemnification does not apply, in a derivative action, to matters
as to which it is adjudged that the director, officer, employee or agent is
liable to Vastera, unless upon court order it is determined that, despite such
adjudication of liability, but in view of all the circumstances of the case, he
is fairly and reasonably entitled to indemnity for expenses, and, in a
non-derivative action, to any criminal proceeding in which such person had
reasonable cause to believe his conduct was unlawful.

    Article VI of Vastera's certificate of incorporation, as amended, provides
that no director of Vastera shall be liable to Vastera or its stockholders for
monetary damages for breach of fiduciary duty as a director to the fullest
extent permitted by the DGCL.

    Article VII of Vastera's certificate of incorporation, as amended, also
provides that Vastera shall indemnify to the fullest extent permitted by
Delaware law any and all of its directors and officers, or former directors and
officers, or any person who may have served at Vastera's request as a director
or officer of another corporation, partnership, joint venture, trust or other
enterprise.

    Reference is made to Section 8 of the underwriting agreement to be filed as
Exhibit 1.1 hereto, pursuant to which the Underwriters have agreed to indemnify
officers and directors of Vastera against certain liabilities under the
Securities Act.

    Vastera has entered into Indemnification Agreements with each director of
Vastera, a form of which is filed as Exhibit 10.7 to this Registration
Statement. Pursuant to such agreements, Vastera will be obligated, to the extent
permitted by applicable law, to indemnify such directors against all expenses,
judgments, fines and penalties incurred in connection with the defense or
settlement of any actions brought against them by reason of the fact that they
were directors of Vastera or assumed certain responsibilities at the direction
of Vastera. Vastera also intends to purchase directors and officers liability
insurance in order to limit its exposure to liability for indemnification of
directors and officers.

ITEM 17. UNDERTAKINGS.

    The undersigned registrant hereby undertakes

    (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

         (i) To include any prospectus required by Section 10(a)(3) of the
             Securities Act of 1933;

        (ii) To reflect in the prospectus any facts or events arising after the
             effective date of the registration statement (or the most recent
             post-effective amendment thereof) which, individually or in the
             aggregate, represent a fundamental change in the information set
             forth in the registration statement. Notwithstanding the foregoing,
             any increase or decrease in volume of securities offered (if the
             total dollar value of securities offered would not exceed that
             which was registered) and any deviation from the low or high end of
             the estimated maximum offering range may be reflected in the form
             of prospectus filed with the Commission pursuant to Rule 424(b) if,
             in the aggregate, the changes in volume and price represent no more
             than 20 percent change in the maximum aggregate offering price set
             forth in the "Calculation of Registration Fee" table in the
             effective registration statement; and

        (iii) To include any material information with respect to the plan of
              distribution not previously disclosed in the registration
              statement or any material change to such information in the
              registration statement.

    (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

    Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to provisions described in Item 14 above, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

    The undersigned registrant hereby undertakes (1) to provide to the
underwriter at the closing specified in the standby underwriting agreement,
certificates in such denominations and registered in such names as required by
the underwriter to permit prompt delivery to each purchaser; (2) that for
purposes of determining any liability under the Act, the information omitted
from the form of prospectus filed as part of this registration statement in
reliance upon Rule 430A and contained in a form of prospectus filed by the
registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Act shall be
deemed to be part of this registration statement as of the time it was declared
effective; and (3) that for the purpose of determining any liability under the
Act, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement

                                      II-5
<PAGE>
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

    The undersigned registrant hereby undertakes to supplement the prospectus,
after the expiration of the subscription period, to set forth the results of the
subscription offer, the transactions by the underwriters during the subscription
period, the amount of unsubscribed securities to be purchased by the
underwriters, and the terms of any subsequent reoffering thereof. If any public
offering by the underwriters is to be made on terms differing from those set
forth on the cover page of the prospectus, a post-effective amendment will be
filed to set forth the terms of such offering.

                    subsidiaries is a party or of which any property of the
                    Company or any of its subsidiaries is the subject which, if
                    determined adversely to the Company or any of its
                    subsidiaries, would individually or in the aggregate have a

                    amendment thereto made by the Company prior to such Time of
                    Delivery (other than the financial statements and related
                    schedules therein, as to which such counsel need express no
                    opinion) contained an untrue statement of a material fact or
                    omitted to state a material fact required to be stated
                    therein or necessary to make the statements therein not
                    misleading or that, as of its date, the Prospectus or any
                    further amendment or supplement thereto made by the Company
                    prior to such Time of Delivery (other than the financial
                    statements and related schedules therein, as to which such
                    counsel need express no opinion) contained an untrue
                    statement of a material fact or omitted to state a material
                    fact necessary to make the statements therein, in the light
                    of the circumstances under which they were made, not
                    misleading or that, as of such Time of Delivery, either the
                    Registration Statement or the Prospectus or any further
                    amendment or supplement thereto made by the Company prior to
                    such Time of Delivery (other than the financial statements
                    and related schedules therein, as to which such counsel need
                    express no opinion) contains an untrue statement of a
                    material fact or omits to state a material fact necessary to
                    make the statements therein, in the light of the
                    circumstances under which they were made, not misleading;
                    and they do not know of any amendment to the Registration
                    Statement required to be filed or of any contracts or other
                    documents of a character required to be filed as an exhibit
                    to the Registration Statement or required to be described in
                    the Registration Statement or the Prospectus which are not
                    filed or described as required;

            (d) On the date of the Prospectus at a time prior to the execution
         of this Agreement, at 9:30 a.m., Boston, Massachusetts time, on the
         effective date of any post-effective amendment to the Registration
         Statement filed subsequent to the date of this Agreement and also at
         each Time of Delivery, Arthur Andersen LLP shall have furnished to you
         a letter or letters, dated the respective dates of delivery thereof, in
         form and substance satisfactory to you, to the effect set forth in
         Annex I hereto (the executed copy of the letter delivered prior to the
         execution of this Agreement is attached as Annex I(a) hereto and a
         draft of the form of letter to be delivered on the effective date of
         any post-effective amendment to the Registration Statement and as of
         each Time of Delivery is attached as Annex I(b) hereto);

            (e) (i) Neither the Company nor any of its subsidiaries shall have
         sustained since the date of the latest audited financial statements
         included in the Prospectus any loss or interference with its business
         from fire, explosion, flood or other calamity, whether or not covered
         by insurance, or from any labor dispute or court or governmental
         action, order or decree, otherwise than as set forth or contemplated in
         the Prospectus, and (ii) since the respective dates as of which
         information is given in the Prospectus there shall not have been any
         change in the capital stock or long-term debt of the Company or any of
         its subsidiaries or



                                       11
<PAGE>

         any change, or any development involving a prospective change, in or
         affecting the general affairs, management, financial position,
         stockholders' equity or results of operations of the Company and its
         subsidiaries, otherwise than as set forth or contemplated in the
         Prospectus, the effect of which, in any such case described in clause
         (i) or (ii), is in the judgment of the Representatives so material and
         adverse as to make it impracticable or inadvisable to proceed with the
         public offering or the delivery of the Shares being delivered at such
         Time of Delivery on the terms and in the manner contemplated in the
         Prospectus;

            (f) On or after the date hereof (i) no downgrading shall have
         occurred in the rating accorded the Company's debt securities or
         preferred stock by any "nationally recognized statistical rating
         organization", as that term is defined by the Commission for purposes
         of Rule 436(g)(2) under the Act, and (ii) no such organization shall
         have publicly announced that it has under surveillance or review, with
         possible negative implications, its rating of any of the Company's debt
         securities or preferred stock;

            (g) On or after the date hereof there shall not have occurred any of
         the following: (i) a suspension or material limitation in trading in
         securities generally on the New York Stock Exchange or on NASDAQ; (ii)
         a suspension or material limitation in trading in the Company's
         securities on NASDAQ; (iii) a general moratorium on commercial banking
         activities declared by either Federal or New York, Virginia or
         Massachusetts State authorities; or (iv) the outbreak or escalation of
         hostilities involving the United States or the declaration by the
         United States of a national emergency or war, if the effect of any such
         event specified in this clause (iv) in the judgment of the
         Representatives makes it impracticable or inadvisable to proceed with
         the public offering or the delivery of the Shares being delivered at
         such Time of Delivery on the terms and in the manner contemplated in
         the Prospectus;

            (h) The Shares to be sold at such Time of Delivery shall have been
         duly listed, subject to notice of issuance, on NASDAQ;

            (i) The Company has obtained and delivered to the Underwriters
         executed copies of an agreement from all stockholders and option
         holders, substantially to the effect set forth in Subsection 5(e)
         hereof in form and substance satisfactory to you;

            (j) The Company shall have complied with the provisions of Section
         5(c) hereof with respect to the furnishing of prospectuses on the
         Boston Business Day next succeeding the date of this Agreement; and

            (k) The Company shall have furnished or caused to be furnished to
         you at such Time of Delivery certificates of officers of the Company
         satisfactory to you as to the accuracy of the representations and
         warranties of the Company herein at and as of such Time of Delivery, as
         to the performance by the Company of all of its obligations hereunder
         to be performed at or prior to such Time of Delivery, as to the matters
         set forth in subsections (a) and (e) of this Section and as to such
         other matters as you may reasonably request.

     8. (a) The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action



                                       12
<PAGE>

or claim as such expenses are incurred; PROVIDED, HOWEVER, that the Company
shall not be liable in any such case to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by any Underwriter through DBSI expressly for use
therein.

     (b) Each Underwriter will indemnify and hold harmless the Company against
any losses, claims, damages or liabilities to which the Company may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through DBSI expressly for use
therein; and will reimburse the Company for any legal or other expenses
reasonably incurred by the Company in connection with investigating or defending
any such action or claim as such expenses are incurred.

     (c) Promptly after receipt by an indemnified party under subsection (a) or
(b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any indemnified party.

     (d) The Company and each subsidiary of the Company, whether direct or
indirect, jointly and severally, agree to indemnify and hold harmless DBSI and
its affiliates and each person, if any, who controls DBSI or its affiliates
within the meaning of either Section 15 of the Act or Section 20 of the Exchange
Act, from and against any and all losses, claims, damages and liabilities
(including, without limitation, any legal or other expenses reasonably incurred
in connection with defending or investigating any such action or claim) (i)
caused by any untrue statement or alleged untrue statement of a material fact
contained in any material prepared by or with the consent of the Company for




                                       13
<PAGE>

distribution to Participants in connection with the Directed Share Program, or
caused by any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading; (ii) caused by the failure of any Participant to pay for and accept
delivery of Directed Shares that the Participant has agreed to purchase; or
(iii) related to, arising out of, or in connection with the Directed Share
Program other than losses, claims, damages or liabilities (or expenses relating
thereto) that are finally judicially determined to have resulted from the bad
faith or gross negligence of DBSI.

     (e) If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above in respect of any losses, claims, damages or liabilities (or actions
in respect thereof) referred to therein, then each indemnifying party shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect the relative benefits received
by the Company on the one hand and the Underwriters on the other from the
offering of the Shares. If, however, the allocation provided by the immediately
preceding sentence is not permitted by applicable law or if the indemnified
party failed to give the notice required under subsection (c) above, then each
indemnifying party shall contribute to such amount paid or payable by such
indemnified party in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the Company on the one hand and
the Underwriters on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations. The
relative benefits received by the Company on the one hand and the Underwriters
on the other shall be deemed to be in the same proportion as the total net
proceeds from the offering (before deducting expenses) received by the Company
bear to the total underwriting discounts and commissions received by the
Underwriters, in each case as set forth in the table on the cover page of the
Prospectus. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company on the one hand or the Underwriters on the other and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Company and the Underwriters
agree that it would not be just and equitable if contributions pursuant to this
subsection (e) were determined by PRO RATA allocation (even if the Underwriters
were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to above in this subsection (e). The amount paid or payable by an indemnified
party as a result of the losses, claims, damages or liabilities (or actions in
respect thereof) referred to above in this subsection (e) shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (e), no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Shares underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (e) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

     (f) The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective



                                       14
<PAGE>

Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company and to each person, if
any, who controls the Company within the meaning of the Act.

     9. (a) If any Underwriter shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery, you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such Shares,
then the Company shall be entitled to a further period of thirty-six hours
within which to procure another party or other parties satisfactory to you to
purchase such Shares on such terms. In the event that, within the respective
prescribed periods, you notify the Company that you have so arranged for the
purchase of such Shares, or the Company notifies you that it has so arranged for
the purchase of such Shares, you or the Company shall have the right to postpone
such Time of Delivery for a period of not more than seven days, in order to
effect whatever changes may thereby be made necessary in the Registration
Statement or the Prospectus, or in any other documents or arrangements, and the
Company agrees to file promptly any amendments to the Registration Statement or
the Prospectus which in your opinion may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any person substituted
under this Section with like effect as if such person had originally been a
party to this Agreement with respect to such Shares.

     (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased does not exceed one-eleventh of the aggregate number of all
the Shares to be purchased at such Time of Delivery, then the Company shall have
the right to require each non-defaulting Underwriter to purchase the number of
shares which such Underwriter agreed to purchase hereunder at such Time of
Delivery and, in addition, to require each non-defaulting Underwriter to
purchase its pro rata share (based on the number of Shares which such
Underwriter agreed to purchase hereunder) of the Shares of such defaulting
Underwriter or Underwriters for which such arrangements have not been made; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.

     (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased exceeds one-eleventh of the aggregate number of all the
Shares to be purchased at such Time of Delivery, or if the Company shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Shares of a defaulting Underwriter or Underwriters,
then this Agreement (or, with respect to the Second Time of Delivery, the
obligations of the Underwriters to purchase and of the Company to sell the
Optional Shares) shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company, except for the expenses to be borne
by the Company and the Underwriters as provided in Section 6 hereof and the
indemnity and contribution agreements in Section 8 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

     10. The respective indemnities, agreements, representations, warranties and
other statements of the Company and the several Underwriters, as set forth in
this Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company,
or any officer or director or controlling person of the Company, and shall
survive delivery of and payment for the Shares.

     11. If this Agreement shall be terminated pursuant to Section 9 hereof, the
Company shall



                                       15
<PAGE>

not then be under any liability to any Underwriter except as provided in
Sections 6 and 8 hereof; but, if for any other reason, any Shares are not
delivered by or on behalf of the Company as provided herein, the Company will
reimburse the Underwriters through you for all out-of-pocket expenses approved
in writing by you, including fees and disbursements of counsel, reasonably
incurred by the Underwriters in making preparations for the purchase, sale and
delivery of the Shares not so delivered, but the Company shall then be under no
further liability to any Underwriter except as provided in Sections 6 and 8
hereof.

     12. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by DBSI on behalf of you as the representatives.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Deutsche Bank
Securities Inc., One South Street, Baltimore, Maryland 21202, Attention:
_________________; with a copy to Deutsche Bank Securities Inc., 31 West 52nd
Street, New York, New York 10019, Attention: General Counsel; and if to the
Company shall be delivered or sent by mail to the address of the Company set
forth in the Registration Statement, Attention: Secretary; provided, however,
that any notice to an Underwriter pursuant to Section 8(c) hereof shall be
delivered or sent by mail, telex or facsimile transmission to such Underwriter
at its address set forth in its Underwriters' Questionnaire, or telex
constituting such Questionnaire, which address will be supplied to the Company
by you upon request. Any such statements, requests, notices or agreements shall
take effect upon receipt thereof.

     13. This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and, to the extent provided in Sections 8 and
10 hereof, the officers and directors of the Company and each person who
controls the Company or any Underwriter, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement. No purchaser of any of the
Shares from any Underwriter shall be deemed a successor or assign by reason
merely of such purchase.

     14. Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     15. This Agreement shall be governed by and construed in accordance with
the laws of the State of Maryland.

     16. This Agreement may be executed by any one or more of the parties hereto
in any number of counterparts, each of which shall be deemed to be an original,
but all such counterparts shall together constitute one and the same instrument.

       If the foregoing is in accordance with your understanding, please sign
and return to us six counterparts hereof, and upon the acceptance hereof by you,
on behalf of each of the Underwriters, this letter and such acceptance hereof
shall constitute a binding agreement between each of the Underwriters and the
Company. It is understood that your acceptance of this letter on behalf of each
of the Underwriters is pursuant to the authority set forth in a form of
Agreement among Underwriters, the form of which shall be submitted to the
Company for examination upon request, but without warranty on your part as to
the authority of the signers thereof.

                                                Very truly yours,

         Pursuant to Section 7(d) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

            (i) They are independent certified public accountants with respect
         to the Company and its subsidiaries within the meaning of the Act and
         the applicable published rules and regulations thereunder;

            (ii) In their opinion, the financial statements and any
         supplementary financial information and schedules (and, if applicable,
         financial forecasts and/or pro forma financial information) examined by
         them and included in the Prospectus or the Registration Statement
         comply as to form in all material respects with the applicable
         accounting requirements of the Act and the related published rules and
         regulations thereunder; and, if applicable, they have made a review in
         accordance with standards established by the American Institute of

cumulative voting and at any meeting held for the purpose of electing directors,
the presence in person or by proxy of the holders of a majority of the shares of

       B. PREFERRED STOCK

          The Preferred Stock shall have the following rights, preferences,
powers, privileges and restrictions, qualifications and limitations.

          1. DIVIDENDS. The holders of shares of Preferred Stock shall be
entitled to receive, as, if and when determined and declared by the Board of

dividend (payable other than in Common Stock or other securities and rights

payment of dividends. Dividends shall be payable pro rata for partial year
periods.

          So long as any shares of Preferred Stock shall be outstanding, no
dividend, whether in cash or property, shall be declared or paid, nor shall any
other distribution be made on the Common Stock, nor shall any shares of any
Common Stock of the Corporation be purchased, redeemed or otherwise acquired for
value by the Corporation (except for acquisitions of Common Stock by the
Corporation pursuant to agreements that permit the Corporation to repurchase
such shares upon termination of services to the Corporation or in the exercise
of the Corporation's right of first refusal upon a proposed transfer of shares
of Preferred Stock) until all dividends set forth in this Section B.1 on the

<PAGE>

Preferred Stock, voting together as a single class, approve of the payment of
such dividends or the redemption of shares of the Corporation's Common Stock. In
the event that dividends are paid on any shares of Common Stock, an additional
dividend shall be paid with respect to all outstanding shares of Preferred Stock
in an amount equal per share (on an as-if-converted basis) to the amount paid or
set aside for each share of Common Stock.

          2. LIQUIDATION, DISSOLUTION OR WINDING UP.

             (a) Other than as set forth in subsections (c) and (d) of this
Section 2, in the event of any Liquidation, before any distribution of assets
shall be made to the holders of the Series A Preferred Stock, Series B Preferred
Stock, Series C Preferred Stock and Series C-1 Preferred Stock and the Common
Stock (collectively referred to as the "Series D Junior Securities"), the holder
of each share of Series D Preferred Stock, Series D-1 Preferred Stock and Series

outstanding shall be entitled to be paid out of the assets of the Corporation
available for distribution to its stockholders an amount equal to (X) $1.176,

Stock) plus (Y) all dividends, including the dividends set forth in Section B.1
above, accrued and unpaid on each such share up to the date of distribution of
the assets of the Corporation to the holders of shares of Combined Series D and
E Preferred Stock to which they are entitled (such amount being referred to as
the "Special Liquidation Preference"). If, upon any such Liquidation, the assets
available for distribution shall be insufficient to pay the holders of shares of
Combined Series D and E Preferred Stock the full amount of the Special
Liquidation Preference to which they shall be entitled, the holders of shares of
Combined Series D and E Preferred Stock, shall share ratably in the distribution
of the assets available therefor in proportion to the respective amounts that
would otherwise be payable in respect of the shares held by them upon such
distribution if all amounts payable on or with respect to such shares were paid
in full;

             (b) Other than as set forth in subsections (c) and (d) of this
Section 2, in the event of a Liquidation, after distribution is made in full
pursuant to subsection (a) of this Section 2, before any distribution of assets
shall be made to the holders of shares of Common Stock, the holder of each share
of Preferred Stock then outstanding shall be entitled to be paid pari passu with
each other holder of shares of Preferred Stock out of the remaining assets of
the Corporation available for distribution to its stockholders an amount
calculated as follows:

                 (i) Each holder of shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series C-1 Preferred Stock shall
receive an amount equal to (X) the applicable Original Purchase Price (as
defined hereinbelow) of each share of such series of Preferred Stock (subject to
appropriate adjustment in the event of any stock dividend, stock split,
combination or other similar recapitalizations affecting such shares of
Preferred Stock) plus (Y) all dividends, including the dividends set forth in
Section B.1 above, accrued and unpaid on such share up to the date of
distribution of the assets of the Corporation to the holders of Preferred Stock
to which they are entitled (such amount being referred to as the "Liquidation
Preference"). For purposes of this Certificate of Amendment, the "Original
Purchase Price" of each share of Series A Preferred Stock, Series B Preferred
Stock, Series C

Stock on an as-if-converted basis (the "Total Shares").

                 (i) an amount per share greater than $7.50, as adjusted for
stock splits, stock dividends, recapitalizations, reclassifications and similar

             (e) The amount deemed distributed to the holders of shares of
Preferred Stock upon any Liquidation shall be the cash or the value of the
property, rights or securities distributed to such holders by the acquiring
person, firm or other entity. The value of such property, rights or other
securities shall be determined in good faith by the Board of Directors of the
Corporation.

           3. VOTING.

             (a) Each holder of outstanding shares of Preferred Stock shall be

             (i) For purposes of subsections 3(c), 3(d), 3(e), 3(f) and 3(g),
without limiting the generality of the foregoing, the authorization or issuance
of any series of preferred stock with preference or priority over, or on parity
with, the Preferred Stock as to the right to receive either dividends or amounts
distributable upon liquidation, dissolution or winding up of the Corporation
shall be deemed to affect adversely the Preferred Stock.

Stock and Series D Preferred Stock and Series D-1 Preferred Stock pursuant to
this section shall be elected by the holders of the Common Stock and Preferred
Stock voting as a single class.

           4. OPTIONAL CONVERSION. The holders of shares of the Preferred Stock
shall have conversion rights as follows (the "Conversion Rights"):

             (a) RIGHT TO CONVERT. Each share of Preferred Stock shall be
convertible, at the option of the holder thereof without the payment of
additional consideration, at any time and from time to time, into such number of
fully paid and nonassessable shares of Common Stock as is determined by dividing
the Original Purchase Price applicable to such


                                       10
<PAGE>

converted share(s) of Preferred Stock by the Adjusted Conversion Price (each as
defined below) in effect at the time of conversion. As of the effective date of
this Certificate of Amendment the Adjusted Conversion Price for the Series A
Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock, the
Series C-1 Preferred Stock, the Series D Preferred Stock, the Series D-1
Preferred Stock and the Series E Preferred Stock initially shall be $2.50,
$3.325, $3.70, $4.92, $4.876, $6.485 and $10.83 per share, respectively.

           In the event of a Liquidation of the Corporation, the Conversion
Rights shall terminate at the close of business on the first full day preceding
the date fixed for the payment of any amounts distributable on liquidation to
the holders of shares of Preferred Stock.

             (b) FRACTIONAL SHARES. No fractional shares of Common Stock shall
be issued upon conversion of the shares of Preferred Stock. In lieu of any
fractional shares to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to such fraction multiplied by the then
effective Adjusted Conversion Price. Whether fractional shares are issuable upon
such conversion shall be determined on the basis of the total number of shares
of Preferred Stock the holder is at the time converting into Common Stock and
the number of shares of Common Stock issuable upon such aggregate conversion.

             (c) MECHANICS OF CONVERSION.

                 (i) When a holder of shares of Preferred Stock elects to
convert shares of Preferred Stock into shares of Common Stock, such holder shall
surrender the certificate or certificates for such shares of Preferred Stock, at
the office of the transfer agent for the Preferred Stock (or at the principal
office of the Corporation if the Corporation serves as its own transfer agent),
together with written notice that such holder elects to convert all or any
number of the shares of the Preferred Stock represented by such certificate or
certificates. Such notice shall state such holder's name or the names of the
nominees in which such holder wishes the certificate or certificates for shares
of Common Stock to be issued. If required by the Corporation, certificates
surrendered for conversion shall be endorsed or accompanied by a written
instrument or instruments of transfer, in form satisfactory to the Corporation,
duly executed by the registered holder or his or its attorney duly authorized in
writing. The date of receipt of such certificates and notice by the transfer
agent (or by the Corporation if the Corporation serves as its own transfer
agent) shall be the conversion date ("Conversion Date"). The Corporation shall,
as soon as practicable after the Conversion Date, issue and deliver at such
office to such holder of Preferred Stock, or to his or its nominees, a
certificate or certificates for the number of shares of Common Stock to which
such stock holder shall be entitled, together with cash in lieu of any fraction
of a share. Such conversion shall be deemed to have been made immediately prior
to the close of business on the Conversion Date, and the person or persons
entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder or holders of such shares
of Common Stock as of such time, and such shares of Common Stock issuable upon
such conversion shall be issued, and deemed issued, as of such time. If the
conversion is in connection with an underwritten offer of securities registered
pursuant to the Securities Act of 1933, as amended, the conversion may, at the
option of any holder tendering shares of Preferred Stock for conversion, be
conditioned upon the closing with the underwriter of the sale of securities
pursuant to such offering, in which event the person(s) entitled to receive the
Common Stock issuable upon such conversion of the


                                       11
<PAGE>

Preferred Stock shall not be deemed to have converted such Preferred Stock until
immediately prior to the closing of such sale of securities, and such shares of
Common Stock issuable upon such conversion shall be issued, and deemed issued,
as of such time.

                 (ii) The Corporation shall, at all times when any shares of
Preferred Stock shall be outstanding, reserve and keep available out of its
authorized but unissued stock, for the purpose of effecting the conversion of
the shares of Preferred Stock (including any Preferred Stock issuable pursuant
to any option originally issued to a holder of shares of Preferred Stock), such
number of its duly authorized shares of Common Stock as shall from time to time
be sufficient to effect the conversion of all outstanding or issuable shares of
Preferred Stock. Before taking any action that would cause an adjustment
reducing the Adjusted Conversion Price below the then par value of the shares of
Common Stock issuable upon conversion of the shares of Preferred Stock, the
Corporation will take any corporate action that may, in the opinion of its
counsel, be necessary to ensure that the Corporation may validly and legally
issue fully paid and nonassessable shares of Common Stock at such Adjusted
Conversion Price. If at any time the number of authorized but unissued shares of
Common Stock shall not be sufficient to effect the conversion of all then
outstanding shares of the Preferred Stock, in addition to such other remedies as
shall be available to the holder of such shares of Preferred Stock, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purposes.

                 (iii) Upon any such conversion, no adjustment to the Adjusted
Conversion Price shall be made for any accrued and unpaid dividends on the
shares of Preferred Stock surrendered for conversion or on the Common Stock
delivered upon conversion.

                 (iv) All shares of Preferred Stock that shall have been
surrendered for conversion as herein provided shall no longer be deemed to be
outstanding and all rights with respect to such shares, including the rights, if
any, to receive notices and to vote, shall immediately cease and terminate on
the Conversion Date, except only the right of the holders thereof to receive
shares of Common Stock in exchange therefor and payment of any accrued and
unpaid Cumulative Dividends thereon and payment of any Liquidation Preference
that has accrued as of the Conversion Date. Any shares of Preferred Stock so
converted shall be retired and canceled and shall not be reissued, and the
Corporation may from time to time take such appropriate action as may be
necessary to reduce the authorized Preferred Stock accordingly.

             (d) ADJUSTMENTS TO CONVERSION PRICE FOR DILUTING ISSUES.

                 (i) SPECIAL DEFINITIONS. For purposes of this Subsection 4(d),

               (ii) NO ADJUSTMENT OF ADJUSTED CONVERSION PRICE. No adjustment in
the number of shares of Common Stock into which the Preferred Stock is
convertible shall be made, by adjustment in the applicable Adjusted Conversion
Price thereof unless the consideration per share (determined pursuant to
Subsection 4(d)(v)) for an Additional Share of Common Stock issued or deemed to
be issued by the Corporation is less than the applicable Adjusted Conversion
Price in effect on the date of, and immediately prior to, the issue of such
Additional Shares.

               (iii) ISSUE OF SECURITIES DEEMED ISSUE OF ADDITIONAL SHARES OF
COMMON STOCK.

                     (A) OPTIONS AND CONVERTIBLE SECURITIES.

Original Issue Date shall issue any Options or Convertible Securities or shall
fix a record date for the determination of holders of any class of securities
entitled to receive any such Options or Convertible Securities, then the maximum

adjustment of such number) issuable upon the exercise of such Options or, in the
case of Convertible Securities and Options therefor, the conversion or exchange
of such Convertible Securities, shall be deemed to be Additional Shares of
Common Stock issued as of the time of such issue or, in case such a record date
shall have been fixed, as of the close of business on such record date, provided
that Additional Shares of Common Stock shall not be deemed to have been issued
unless the consideration per share (determined pursuant to Subsection 4(d)(v)
hereof) of such Additional Shares of Common Stock would be less than the
applicable Adjusted Conversion Price in effect on the date of and immediately
prior to such issue, or such record date, as the case may be, and provided
further that in any such case in which Additional Shares of Common Stock are
deemed to be issued:

                         (I) no further adjustment in the Adjusted Conversion
                    Price shall be made upon the subsequent issue of Convertible
                    Securities or shares of Common Stock upon the exercise of
                    such Options or conversion or exchange of such Convertible
                    Securities;

                         (II) if such Options or Convertible Securities by their
                    terms provide, with the passage of time or otherwise, for
                    any increase in the consideration payable to the
                    Corporation, or decrease in the number of shares of Common
                    Stock issuable, upon the exercise, conversion or exchange
                    thereof, the Adjusted Conversion Price computed upon the
                    original issue thereof (or upon the occurrence of a record
                    date with respect thereto), and any subsequent adjustments
                    based thereon, shall, upon any such increase or decrease
                    becoming effective, be recomputed to reflect such increase
                    or decrease insofar as it affects such Options or the rights
                    of conversion or exchange under such Convertible Securities;

                         (III) no readjustment pursuant to clause (II) above
                    shall have the effect of increasing the Adjusted Conversion
                    Price to an amount which exceeds the lower of (i) the
                    Conversion Price on the original adjustment date, or (ii)
                    the Conversion Price that would have resulted from any
                    issuance of Additional Shares of Common Stock between


                                       14
<PAGE>

                    the original adjustment date and such readjustment date; and

                         (IV) upon the expiration or termination of any
                    unexercised Option, the Adjusted Conversion Price shall not
                    be readjusted, but the Additional Shares of Common Stock
                    deemed issued as the result of the original issue of such
                    Option shall not be deemed issued for the purposes of any
                    subsequent adjustment of the Adjusted Conversion Price.

                    (B) STOCK DIVIDENDS. In the event the Corporation at any
time or from time to time shall declare or pay any dividend on the Common Stock
payable in Common Stock, then in any such event, Additional Shares of Common
Stock shall be deemed to have been issued immediately after the close of
business on the record date for the determination of holders of any class of
securities entitled to receive such dividend; provided, however, that if such
record date is fixed and such dividend is not fully paid, the only Additional
Shares of Common Stock deemed to have been issued will be the number of shares
of Common Stock actually issued in such dividend, and such shares will be deemed
to have been issued as of the close of business on such record date, and the
Adjusted Conversion Price shall be recomputed accordingly.

               (iv) ADJUSTMENT OF CONVERSION PRICE UPON ISSUANCE OF ADDITIONAL
SHARES OF COMMON STOCK. In the event the Corporation shall issue Additional
Shares of Common Stock after the Original Issue Date of the first share of each
series of Preferred Stock (including Additional Shares of Common Stock deemed to
be issued pursuant to Subsection 4(d)(iii)), without consideration or for a
consideration per share less than the applicable Adjusted Conversion Price in
effect on the date of and immediately prior to such issue, then and in such
event, such Adjusted Conversion Price for such series of Preferred Stock shall
be reduced, concurrently with such issue, to an amount determined by multiplying
the Adjusted Conversion Price in effect on the date of and immediately prior to
such issue, by a fraction:

                    (A) the numerator of which shall be (I) the number of shares
of Common Stock outstanding immediately prior to the issuance of such Additional
Shares of Common Stock (after giving effect to the issuance of Common Stock upon
the conversion of the shares of Preferred Stock outstanding immediately prior to
the issuance of such additional shares of Common Stock), plus (II) the number of
shares of Common Stock that the net aggregate consideration received by the
Corporation for the total number of such Additional Shares of Common Stock so
issued would purchase at the Adjusted Conversion Price in effect prior to
adjustment, and

                    (B) the denominator of which shall be (I) the number of
shares of Common Stock outstanding immediately prior to the issuance of such
Additional Shares of Common Stock (after giving effect to the issuance of Common
Stock upon the conversion of the shares of Preferred Stock outstanding
immediately prior to the issuance of such additional shares of Common Stock),
plus (II) the number of such Additional Shares of Common Stock so issued.


                                       15
<PAGE>

               (v) DETERMINATION OF CONSIDERATION. For purposes of this
Subsection 4(d), the consideration received by the Corporation for the issue of
any Additional Shares of Common Stock shall be computed as follows:

                   (A) CASH AND PROPERTY: Such consideration shall:

                       (I) insofar as it consists of cash, be computed as the
               aggregate net cash received by the Corporation, after deducting
               any underwriting discounts, commissions and fees and excluding
               amounts paid or payable for accrued interest or accrued
               dividends;

                      (II) insofar as it consists of property other than cash,
               be computed at the fair market value thereof at the time of such
               issue, as determined in good faith by the Board of Directors; and

                     (III) in the event Additional Shares of Common Stock are
               issued together with other shares or securities or other assets
               of the Corporation for consideration which covers both, be the
               proportion of such consideration so received in respect of the
               Additional Shares of Common Stock, computed as provided in
               clauses (I) and (II) above, as determined in good faith by the
               Board of Directors.

                    (B) OPTIONS AND CONVERTIBLE SECURITIES. The consideration
per share received by the Corporation for Additional Shares of Common Stock
deemed to have been issued pursuant to Subsection 4(d)(iv)(A), relating to
Options and Convertible Securities, shall be determined by dividing

             (x) the total amount, if any, received or receivable by the
Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Corporation upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such Options for Convertible Securities and the
conversion or exchange of such Convertible Securities, by

             (y) the maximum number of shares of Common Stock (as set forth in
the instruments relating thereto, without regard to any provision contained
therein for a subsequent adjustment of such number) issuable upon the exercise
of such Options or the conversion or exchange of such Convertible Securities.

                    (C) STOCK DIVIDENDS. Any Additional Shares of Common Stock
relating to stock dividends shall be deemed to have been issued for no
consideration.


                                       16
<PAGE>

                 (vi) ADJUSTMENT FOR SUBDIVISIONS, COMBINATIONS OR CONSOLIDATION
OF COMMON STOCK. In the event the outstanding shares of Common Stock shall be
subdivided, by stock split or otherwise (but other than by stock dividend, which
is addressed in Subsection B(4)(d)(iii)(B)), into a greater number of shares of
Common Stock, the applicable Adjusted Conversion Price in effect immediately
prior to such subdivision shall, concurrently with the effectiveness of such
subdivision, be decreased proportionately. In the event the outstanding shares
of Common Stock shall be combined or consolidated, by reclassification or
otherwise, into a lesser number of shares of Common Stock, the applicable
Adjusted Conversion Price in effect immediately prior to such combination or
consolidation shall, concurrently with the effectiveness of such combination or
consolidation, be increased proportionately.

                 (vii) ADJUSTMENT FOR MERGER OR REORGANIZATION, ETC. In case of
any recapitalization, consolidation or merger of the Corporation with or into
another corporation or the sale of all or substantially all of the assets of the
Corporation to another corporation (other than a subdivision or combination
provided for elsewhere in this Section 4 and other than a consolidation, merger
or sale which is treated as a Liquidation pursuant to Subsection 2(c)), each
share of Preferred Stock shall thereafter be convertible into the kind and
amount of shares of stock or other securities or property to which a holder of
the number of shares of Common Stock of the Corporation deliverable upon
conversion of such Preferred Stock would have been entitled upon such
consolidation, merger or sale; and, in such case, appropriate adjustment (as
determined in good faith by he Board of Directors) shall be made in the
application of the provisions in this Section 4 set forth with respect to the
rights and interest thereafter of the holders of the Preferred Stock, to the end
that the provisions set forth in this Section 4 (including provisions with
respect to changes in and other adjustments of the Adjusted Conversion Price)
shall thereafter be applicable, as nearly as reasonably may be, in relation to
any shares of stock or other property thereafter deliverable upon the conversion
of the Preferred Stock.

                 (viii) ADJUSTMENTS FOR OTHER DISTRIBUTIONS. In the event the
Corporation at any time or from time to time makes, or fixes a record date for
the determination of holders of Common Stock entitled to receive, any
distribution payable in securities of the Corporation other than shares of
Common Stock and other than as otherwise adjusted in this Section B(4) then, and
in each such event, provision shall be made such that the holders of each share
of Preferred Stock shall receive upon conversion thereof, in addition to the
number of shares of Common Stock receivable thereupon, the amount of the
securities of the Corporation that they would have received had their shares of
Preferred Stock been converted into shares of Common Stock on the date of such
event and had then thereafter, during the period from the date of such event to
and including the date of conversion, retained such securities receivable by
them as aforesaid during such period, subject to all other adjustments called
for during such period under this Section B(4) with respect to the rights of the
holders of such shares of Preferred Stock.

             (e) NO IMPAIRMENT. The Corporation will not, by amendment of its
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in carrying out all of the provisions of this
Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of shares
of Preferred Stock against impairment.


                                       17
<PAGE>

             (f) CERTIFICATE AS TO ADJUSTMENTS. Upon the occurrence of each
adjustment or readjustment of the Adjusted Conversion Price pursuant to this
Section 4, the Corporation at its expense shall promptly compute such adjustment
or readjustment in accordance with the terms hereof and furnish to each holder
of shares of Preferred Stock a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any holder of shares of Preferred Stock, furnish or cause to be
furnished to such holder a similar certificate setting forth (i) such
adjustments and readjustments, (ii) the Adjusted Conversion Price then in
effect, and (iii) the number of shares of Common Stock and the amount, if any,
of other property which then would be received upon the conversion of shares of
Preferred Stock.

             (g) NOTICE OF RECORD DATE: In the event:

                 (i) that the Corporation takes a record of the holders of any
class of securities for the purpose of determining the holders thereof who are
entitled to receive any dividend (other than a cash dividend) or other
distribution, any right to subscribe for, purchase or otherwise acquire any
shares of stock of any class of any other securities or property, or to receive
any other right;

                 (ii) that the Corporation subdivides or combines its
outstanding shares of Common Stock;

                 (iii) of any reclassification of the Common Stock of the
Corporation (other than a subdivision or combination of its outstanding shares
of Common Stock or a stock dividend or stock distribution thereon), or of any
consolidation or merger of the Corporation into or with another corporation, or
of the sale of all or substantially all of the assets of the Corporation;

                 (iv) of the involuntary or voluntary dissolution, liquidation
or winding up of the Corporation; or

                 (v) any recapitalization of the capital stock of the
Corporation;

then the Corporation shall cause to be filed at its principal office or at the
office of the transfer agent of the shares Preferred Stock, and shall cause to
be mailed to the holders of the shares Preferred Stock at their last addresses
as shown on the records of the Corporation or such transfer agent, at least
fifteen (15) days before the record date specified below, a notice stating

                     (A) the recorded date of such dividend, distribution,
subdivision or combination, or, if a record is not to be taken, the date as of
which the holders of the applicable class of securities of record to be entitled
to such dividend, distribution, subdivision or combination are to be determined,
or

                     (B) the date of which such recapitalization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up is expected to become effective, and the date as of which it is
expected that holders of the applicable class of securities of record shall be
entitled to exchange their shares of the applicable class of securities


                                       18
<PAGE>

for securities or other property deliverable upon such recapitalization,
reclassification, consolidation, merger, sale, dissolution or winding up.

             (h) PAYMENT OF TAXES. The Corporation shall pay all taxes (other
than taxes based upon income) and other governmental charges that may be imposed
with respect to the issue or delivery of shares of Common Stock upon conversion
of shares of Preferred Stock under Sections 4 or 5 hereof, excluding any tax or
other charge imposed in connection with any transfer involved in the issue and
delivery of shares of Common Stock in a name other than that in which the shares
of Preferred Stock so converted were registered.

           5. MANDATORY CONVERSION.

             (a) Upon the effective date of a registration statement under the
Securities Act of 1933, as amended, covering the offer and sale of Common Stock
for the account of the Corporation in which the per share price is at least
$14.80 (subject to adjustment for any stock dividend, stock split, combination
or other similar recapitalizations) and the aggregate net cash received by the
Corporation (after deducting any underwriting discounts, commissions and fees or
similar commissions, compensation or concessions paid or allowed by the
Corporation in connection with such issue or sale) are at least $15,000,000,
then effective upon the closing of the sale of such shares by the Corporation
pursuant to such offering, all outstanding shares of Preferred Stock shall
automatically convert to shares of Common Stock in the manner provided elsewhere
herein, including, without limitation, the adjustments contemplated by Section
B(4).

             (b) All certificates evidencing shares of Preferred Stock will be
required to be surrendered in connection with the mandatory conversion described
herein and such certificates shall, from and after the date such certificates
are so required to be surrendered, be deemed to have been retired and canceled
and the shares of Preferred Stock represented thereby converted into Common
Stock for all purposes, notwithstanding the failure of the holder or holders
thereof to surrender such certificates. The Corporation shall, as soon as
practicable after the date of conversion, issue and deliver at the office of the
transfer agent for the shares of Preferred Stock (or at the principal office of
the Corporation if the Corporation serves as its own transfer agent) to such
holder of shares of Preferred Stock, or to his or its nominee, a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled, together with cash in lieu of any fraction of a share). The
Corporation may thereafter take such appropriate action as may be necessary to
reduce the authorized number of shares of Preferred Stock accordingly.

           6. REDEMPTION AT OPTION OF HOLDER.

             (a) At the option of the holders of a majority of the aggregate
number of shares of Series A Preferred Stock and Series B Preferred Stock,
voting together as a single class, the Corporation shall redeem, commencing on
August 7, 2002 (the "Redemption Trigger Date") and continuing on the immediately
succeeding two anniversaries thereof, in three (3) installments (each such date
a "Preferred Stock Redemption Date"), the number of shares of Series A Preferred
Stock and Series B Preferred Stock held by all holders as specified below. To
exercise their rights of redemption provided in this Section 6, the holders of a
majority of the


                                       19
<PAGE>

aggregate number of shares of Series A Preferred Stock and Series B Preferred
Stock shall deliver to the secretary or the treasurer of the Corporation no less
than sixty (60) days prior to the applicable Preferred Stock Redemption Date a
written notice informing the Corporation of the exercise of the redemption
rights by the holders of shares of Series A Preferred Stock and Series B
Preferred Stock. No later than thirty (30) days after the applicable Preferred
Stock Redemption Date, the Corporation shall redeem the number of shares of
Series A Preferred Stock and Series B Preferred Stock specified below for each
applicable Preferred Stock Redemption Date, by paying in cash therefor, the
greater of (i) the fair market value of such shares, as initially determined at
the first Preferred Stock Redemption Date in accordance with Section 6(f) below,
or (ii) the Original Purchase Price plus all accrued but unpaid dividends on
such shares, including, without limitation, all dividends contemplated by
Section B(1) (the greater of such amounts with respect to Series A Preferred
Stock being referred to as the "Series A Redemption Price" and the greater of
such amounts with respect to Series B Preferred Stock being referred to as the
"Series B Redemption Price"). With respect to (i) the first Preferred Stock
Redemption Date the Corporation shall be required to redeem in aggregate
one-third (1/3) of the aggregate number of shares of Series A Preferred Stock
and Series B Preferred Stock originally issued; (ii) the second Preferred Stock
Redemption Date the Corporation shall be required to redeem in aggregate, taking
into effect the prior redemption, one-half (1/2) of the aggregate remaining
number of issued and outstanding shares of Series A Preferred Stock and Series B
Preferred Stock; and (iii) the third Preferred Stock Redemption Date the
Corporation shall be required to redeem in aggregate, taking into effect all
prior redemptions, the aggregate remaining number of issued and outstanding
shares of Series A Preferred Stock and Series B Preferred Stock originally
issued. In the event that the holders of a majority of the aggregate number of
shares of Series A Preferred Stock and Series B Preferred Stock, voting together
as a single class, do not elect to exercise their redemption right on the
Redemption Trigger Date in the manner provided herein, the holders of a majority
of the aggregate number of shares of Series A Preferred Stock and Series B
Preferred Stock, voting together as a single class, may elect to exercise such
redemption right at a subsequent anniversary; provided, however, except as set
forth in the immediately succeeding sentence, in no event shall the Corporation
be required to redeem more than one-third (1/3) of the aggregate number of
shares of Series A Preferred Stock and Series B Preferred Stock originally
issued by the Corporation on any Preferred Stock Redemption Date. If the
Corporation is unable to redeem in full all shares tendered for redemption on a
Preferred Stock Redemption Date, then, on the next Preferred Stock Redemption
Date, the Corporation shall be required to redeem all the previously tendered
but unredeemed shares of Series A Preferred Stock and Series B Preferred Stock
plus all new shares of such stock tendered for redemption, which may cause the
Corporation to redeem more than one-third (1/3) of the aggregate number of
shares of Series A Preferred Stock and Series B Preferred Stock originally
issued by the Corporation. Dividends on the shares of Series A Preferred Stock
and Series B Preferred Stock shall continue to accrue until redemption, and
accrued and unpaid dividends shall be paid at redemption.

             (b) At the option of the holders of a majority of the aggregate
number of shares of Combined C Preferred Stock, voting together as a single
class, the Corporation shall redeem, commencing on the Redemption Trigger Date
and continuing on the immediately succeeding two anniversaries thereof, in three
(3) installments (each such date also being referred to as a "Preferred Stock
Redemption Date"), the number of shares of Combined C Preferred Stock held by
all holders as specified below. To exercise their rights of redemption provided
in


                                       20
<PAGE>

this Section 6, the holders of a majority of the aggregate number of shares of
Combined C Preferred Stock shall deliver to the secretary or the treasurer of
the Corporation no less than sixty (60) days prior to the applicable Preferred
Stock Redemption Date a written notice informing the Corporation of the exercise
of the redemption rights by the holders of shares of Combined C Preferred Stock.
No later than thirty (30) days after the applicable Preferred Stock Redemption
Date, the Corporation shall redeem the number of shares of Combined C Preferred
Stock specified below for each applicable Preferred Stock Redemption Date, by
paying in cash therefor, the greater of (i) the fair market value of such
shares, as initially determined at the first Preferred Stock Redemption Date in
accordance with Section 6(f) below, or (ii) the Original Purchase Price plus all
accrued but unpaid dividends on such shares, including, without limitation, all
dividends contemplated by Section B(1) (the greater of such amounts with respect
to Series C Preferred Stock being referred to as the "Series C Redemption Price"
and the greater of such amounts with respect to Series C-1 Preferred Stock being
referred to as the "Series C-1 Redemption Price"). With respect to (i) the first
Preferred Stock Redemption Date the Corporation shall be required to redeem in
aggregate one-third (1/3) of the aggregate number of shares of Combined C
Preferred Stock originally issued; (ii) the second Preferred Stock Redemption
date the Corporation shall be required to redeem in aggregate, taking into
effect the prior redemption, one-half (1/2) of the aggregate remaining number of
issued and outstanding shares of Combined C Preferred Stock; and (iii) the third
Preferred Stock Redemption Date the Corporation shall be required to redeem in
aggregate, taking into effect all prior redemptions, the aggregate remaining
number of issued and outstanding shares of Combined C Preferred Stock originally
issued. In the event that the holders of a majority of the aggregate number of
shares of Combined C Preferred Stock, voting together as a single class, do not
elect to exercise their redemption right on the Redemption Trigger Date in the
manner provided herein, the holders of a majority of the aggregate number of
shares of Combined C Preferred Stock, voting together as a single class, may
elect to exercise such redemption right at a subsequent anniversary; provided,
however, except as set forth in the immediately succeeding sentence, in no event
shall the Corporation be required to redeem more than one-third (1/3) of the
aggregate number of shares of Combined C Preferred Stock originally issued by
the Corporation on any Preferred Stock Redemption Date. If the Corporation is
unable to redeem in full all shares tendered for redemption on a Preferred Stock
Redemption Date, then, on the next Preferred Stock Redemption Date, the
Corporation shall be required to redeem all the previously tendered but
unredeemed shares of Combined C Preferred Stock plus all new shares of such
stock tendered for redemption, which may cause the Corporation to redeem more
than one-third (1/3) of the aggregate number of shares of Combined Series C
Preferred Stock originally issued by the Corporation. Dividends on the shares of
Combined C Preferred Stock shall continue to accrue until redemption, and
accrued and unpaid dividends shall be paid at redemption.

             (c) At the option of the holders of a majority of the aggregate
number of shares of the Series D Preferred Stock and the Series D-1 Preferred
Stock, voting together as a single class, the Corporation shall redeem,
commencing on the Redemption Trigger Date and continuing on the immediately
succeeding two anniversaries thereof, in three (3) installments (each such date
also being referred to as a "Preferred Stock Redemption Date"), the number of
shares of Series D Preferred Stock and Series D-1 Preferred Stock held by all
holders as specified below. To exercise their rights of redemption provided in
this Section 6, the holders of a majority of the aggregate number of shares of
Series D Preferred Stock and Series D-1 Preferred Stock shall deliver to the
secretary or the treasurer of the Corporation no less than sixty


                                       21
<PAGE>

(60) days prior to the applicable Preferred Stock Redemption Date a written
notice informing the Corporation of the exercise of the redemption rights by the
holders of shares of Series D Preferred Stock and Series D-1 Preferred Stock. No
later than thirty (30) days after the applicable Preferred Stock Redemption
Date, the Corporation shall redeem the number of shares of Series D Preferred
Stock and Series D-1 Preferred Stock specified below for each applicable
Preferred Stock Redemption Date, by paying in cash therefor, the greater of (i)
the fair market value of such shares, as initially determined at the first
Preferred Stock Redemption Date in accordance with Section 6(f) below, or (ii)
the Original Purchase Price plus all accrued but unpaid dividends on such
shares, including, without limitation, all dividends contemplated by Section
B(1) (the greater of such amounts with respect to Series D Preferred Stock being
referred to as the "Series D Redemption Price" and the greater of such amounts
with respect to Series D-1 Preferred Stock being referred to as the "Series D-1
Redemption Price". With respect to (i) the first Preferred Stock Redemption Date
the Corporation shall be required to redeem in aggregate one-third (1/3) of the
aggregate number of shares of Series D Preferred Stock and Series D-1 Preferred
Stock originally issued; (ii) the second Preferred Stock Redemption date the
Corporation shall be required to redeem in aggregate, taking into effect the
prior redemption, one-half (1/2) of the aggregate remaining number of issued and
outstanding shares of Series D Preferred Stock and Series D-1 Preferred Stock;
and (iii) the third Preferred Stock Redemption Date the Corporation shall be
required to redeem in aggregate, taking into effect all prior redemptions, the
aggregate remaining number of issued and outstanding shares of Series D
Preferred Stock and Series D-1 Preferred Stock. In the event that the holders of
a majority of the aggregate number of shares of Series D Preferred Stock and
Series D-1 Preferred Stock, voting together as a single class, do not elect to
exercise their redemption right on the Redemption Trigger Date in the manner
provided herein, the holders of a majority of the aggregate number of shares of
Series D Preferred Stock and Series D-1 Preferred Stock, voting together as a
single class, may elect to exercise such redemption right at a subsequent
anniversary; provided, however, except as set forth in the immediately
succeeding sentence, in no event shall the Corporation be required to redeem
more than one-third (1/3) of the aggregate number of shares of Series D
Preferred Stock and Series D-1 Preferred Stock originally issued by the
Corporation on any Preferred Stock Redemption Date. If the Corporation is unable
to redeem in full all shares tendered for redemption on a Preferred Stock
Redemption Date, then, on the next Preferred Stock Redemption Date, the
Corporation shall be required to redeem all the previously tendered but
unredeemed shares of Series D Preferred Stock and Series D-1 Preferred Stock
plus all new shares of such stock tendered for redemption, which may cause the
Corporation to redeem more than one-third (1/3) of the aggregate number of
shares of Series D Preferred Stock and Series D-1 Preferred Stock originally
issued by the Corporation. Dividends on the shares of Series D Preferred Stock
and Series D-1 Preferred Stock shall continue to accrue until redemption, and
accrued and unpaid dividends shall be paid at redemption.

             (d) At the option of the holders of a majority of the aggregate
number of shares of the Series E Preferred Stock, voting as a single class, the
Corporation shall redeem, commencing on the Redemption Trigger Date and
continuing on the immediately succeeding two anniversaries thereof, in three (3)
installments (each such date also being referred to as a "Preferred Stock
Redemption Date"), the number of shares of Series E Preferred Stock held by all
holders as specified below. To exercise their rights of redemption provided in
this Section 6, the holders of a majority of the aggregate number of shares of
Series E Preferred Stock shall deliver to the secretary or the treasurer of the
Corporation no less than sixty (60) days prior to the


                                       22
<PAGE>

applicable Preferred Stock Redemption Date a written notice informing the
Corporation of the exercise of the redemption rights by the holders of shares of
Series E Preferred Stock. No later than thirty (30) days after the applicable
Preferred Stock Redemption Date, the Corporation shall redeem the number of
shares of Series E Preferred Stock specified below for each applicable Preferred
Stock Redemption Date, by paying in cash therefor, the greater of (i) the fair
market value of such shares, as initially determined at the first Preferred
Stock Redemption Date in accordance with Section 6(f) below, or (ii) the
Original Purchase Price plus all accrued but unpaid dividends on such shares,
including, without limitation, all dividends contemplated by Section B(1) (the
greater of such amounts with respect to the Series E Preferred Stock being
referred to as the "Series E Redemption Price"). With respect to (i) the first
Preferred Stock Redemption Date the Corporation shall be required to redeem in
aggregate one-third (1/3) of the aggregate number of shares of Series E
Preferred Stock originally issued; (ii) the second Preferred Stock Redemption
date the Corporation shall be required to redeem in aggregate, taking into
effect the prior redemption, one-half (1/2) of the aggregate remaining number of
issued and outstanding shares of Series E Preferred Stock; and (iii) the third
Preferred Stock Redemption Date the Corporation shall be required to redeem in
aggregate, taking into effect all prior redemptions, the aggregate remaining
number of issued and outstanding shares of Series E Preferred Stock. In the
event that the holders of a majority of the aggregate number of shares of Series
E Preferred Stock, voting as a single class, do not elect to exercise their
redemption right on the Redemption Trigger Date in the manner provided herein,
the holders of a majority of the aggregate number of shares of Series E
Preferred Stock, voting as a single class, may elect to exercise such redemption
right at a subsequent anniversary; provided, however, except as set forth in the
immediately succeeding sentence, in no event shall the Corporation be required
to redeem more than one-third (1/3) of the aggregate number of shares of Series
E Preferred Stock originally issued by the Corporation on any Preferred Stock
Redemption Date. If the Corporation is unable to redeem in full all shares
tendered for redemption on a Preferred Stock Redemption Date, then, on the next
Preferred Stock Redemption Date, the Corporation shall be required to redeem all
the previously tendered but unredeemed shares of Series E Preferred Stock plus
all new shares of such stock tendered for redemption, which may cause the
Corporation to redeem more than one-third (1/3) of the aggregate number of
shares of Series E Preferred Stock originally issued by the Corporation.
Dividends on the shares of Series E Preferred Stock shall continue to accrue
until redemption, and accrued and unpaid dividends shall be paid at redemption.

             (e) Notwithstanding anything to the contrary contained elsewhere in
this Section 6, if shares of Preferred Stock are simultaneously tendered for
redemption pursuant to Sections 6(a), 6(b), 6(c) and 6(d), or any combination
thereof, and the Corporation is unable to redeem in full all such shares
tendered because the Corporation has insufficient legal capital available to
effect such redemptions, the Corporation shall allocate its available legal
capital to the redemption of shares of Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series C-1 Preferred Stock, Series D
Preferred Stock, Series D-1 Preferred Stock and Series E Preferred Stock based
on the following formula: the aggregate legal capital available to effect such
redemptions shall be multiplied by a fraction, (i) the numerator of which shall
be equal to (X) the number of shares of the applicable series of Preferred Stock
tendered for redemption multiplied by (Y) the Series A Redemption Price, the
Series B Redemption Price, the Series C Redemption Price, the Series C-1
Redemption Price, the Series D Redemption Price, the Series D-1 Redemption Price
or the Series E Redemption Price, as applicable, and (ii) the


                                       23
<PAGE>

denominator of which shall be the aggregate of (A) the number of shares of
Series A Preferred Stock tendered for redemption multiplied by the Series A
Redemption Price, (B) the number of shares of Series B Preferred Stock tendered
for redemption multiplied by the Series B Redemption Price, (C) the number of
shares of Series C Preferred Stock tendered for redemption multiplied by the
Series C Redemption Price, (D) the number of shares of Series C-1 Preferred
Stock tendered for redemption multiplied by the Series C-1 Redemption Price, (E)
the number of shares of Series D Preferred Stock tendered for redemption
multiplied by the Series D Redemption Price, (F) the number of shares of Series
D-1 Preferred Stock tendered for redemption multiplied by the Series D-1
Redemption Price and (G) the number of shares of Series E Preferred Stock
tendered for redemption multiplied by the Series E Redemption Price.

             (f) Within ten (10) days of receipt by the Corporation of the
notice of the holders of shares of Preferred Stock electing to exercise their
Redemption Rights, a disinterested appraisal firm which is a member of a
recognized professional association reasonably acceptable to the Corporation and
the holders of a majority of the shares of Preferred Stock to be redeemed shall
determine the fair market value as set forth below. If the parties are unable to
agree on an appraisal firm within ten (10) days after the receipt of such
redemption notice by the Corporation, a firm shall be selected by lot from the
top-tier New York-based investment banking firms, after the Corporation and the
redeeming holders of shares of Preferred Stock have each eliminated one such
firm. The firm so selected shall then make a determination of the fair market
value, and, using such determination of fair market value, shall calculate the
Series A Redemption Price, the Series B Redemption Price, the Series C
Redemption Price, the Series C-1 Redemption Price, the Series D Redemption
Price, the Series D-1 Redemption Price or the Series E Redemption Price, as
applicable. The selection and determination of such firms shall be final and
binding upon all parties. The expenses of such firms shall be borne equally by
the holders of the shares of Preferred Stock, as a group, and the Corporation.

             (g) In the event the Corporation does not pay in full to the
holders of shares of Preferred Stock the aggregate Series A Redemption Price,
Series B Redemption Price, Series C Redemption Price, Series C-1 Redemption
Price, Series D Redemption Price, Series D-1 Redemption Price or the Series E
Redemption Price, as applicable (the "Aggregate Redemption Price"), owed to such
redeeming holders by the end of the thirty (30) day payment period described in
Section 6(a) or 6(b), as applicable, or the Corporation is unable to redeem all
of the shares of Preferred Stock tendered for redemption, such unpaid portion of
the Aggregate Redemption Price shall accrue interest at the rate of fifteen
percent (15%) per annum and such accrued interest shall be payable on the last
day of each calendar quarter. If ninety (90) days after the holders of a
majority of the outstanding shares of Preferred Stock have delivered a notice to
the Corporation of its failure to pay the unpaid portion of the Aggregate
Redemption Price, the Corporation is unable to pay the unpaid portion and any
accrued interest thereon in full then the Corporation shall be deemed to be in
default of its redemption obligations hereunder. In the event of such default,
the holders of a majority of the shares of Preferred Stock shall have the right
and be entitled to elect a majority of the Board of Directors until such time as
the Corporation has cured such default. Once such default has been cured, the
right of holders of a majority of the shares of Preferred Stock shall terminate
and the voting provisions set forth elsewhere herein shall govern.

           7. AMENDMENTS. No provision of the terms of any series or class of
Preferred Stock may be amended, modified or waived without the written consent
or affirmative vote of the holders of at least a majority of the then
outstanding shares of the respective series or class, voting separately as a
class; provided, however, that in the event that an amendment, modification or
waiver of the terms of one series or class of Preferred Stock would result in
any of the rights of the holders of another series or class of Preferred Stock
being adversely affected, then the amendment, modification or waiver of such
terms may not be effected without the written consent of a majority of the
holders of each series of Preferred Stock affected, voting separately by series
or class.

preemptive rights, except as granted by the Corporation pursuant to written
agreements.

the Director's duty of loyalty to the Corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involved intentional misconduct or
a knowing violation of law, (iii) under Section 174 of the General Corporation
Law of Delaware, or (iv) for any transaction from which the Director derived an
improper personal benefit.

           If the General Corporation Law of Delaware or any other statute of
the State of Delaware hereafter is amended to authorize the further elimination
or limitation of the liability of Directors of the Corporation, then the
liability of a Director of the Corporation shall be limited to the fullest
extent permitted by the statutes of the State of Delaware, as so amended, and
such elimination or imitation of liability shall be in addition to, and not in
lieu of , the limitation of the liability of a Director provided by the
foregoing provisions of this Sixth Article.

           Any repeal of or amendment to this Sixth Article shall be prospective
only and shall not adversely affect any limitation on the liability of a
Director of the Corporation existing at the time of such repeal or amendment.

                  Meetings of stockholders may be held within or without the

                                   ARTICLE IX

                  Election of directors at an annual or special meeting of
stockholders need not be by written ballot unless the Bylaws of the Corporation

                  A. At each annual meeting of stockholders, directors of the
Corporation shall be elected to hold office until the expiration of the term for
which they are elected, and until their successors have been duly elected and
qualified; except that if any such election shall not be so held, such election
shall take place at a stockholders' meeting called and held in accordance with
the Delaware General Corporation Law. Upon the filing of this Amended and
Restated Certificate of Incorporation, the directors of the Corporation shall be
divided into three classes as nearly equal in size as is practicable, hereby
designated as Class I, Class II and Class III. The term of office of the initial
Class I directors shall expire at the first annual meeting of stockholders
following the consummation of the Company's initial public offering, the term of
office of the initial Class II directors shall expire at the second succeeding
annual meeting of stockholders and the term of office of the initial Class III
directors shall expire at the third succeeding annual meeting of stockholders.
For the purposes hereof, the initial Class I, Class II and Class III directors
shall be designated by the Board of Directors or in the Bylaws of the
Corporation. At each annual meeting directors to replace those of a Class whose
terms expire at such annual meeting shall be elected to hold office until the
third succeeding annual meeting and until their respective successors shall have
been duly elected and qualified. If the number of directors is hereafter
changed, any newly created directorships or decrease in directorships shall be
so apportioned among the classes as to make all classes as nearly equal in
number as is practicable.

                  B. Vacancies occurring on the Board of Directors for any
reason may be filled by vote of a majority of the remaining members of the Board
of Directors, although less than a quorum, at a meeting of the Board of
Directors. A person so elected by the Board of Directors to fill a vacancy shall

                            ARTICLE 1 - STOCKHOLDERS

        1.1 Place of Meeting. All meetings of stockholders shall be held at such
place within or without the State of Delaware as may be designated from time to
time by the Board of Directors or the President or, if not so designated, at the
registered office of the corporation.

        1.2 Annual Meeting. The annual meeting of stockholders for the election
of directors and for the transaction of such other business as may properly be
brought before the meeting shall be held at such date, time and place as may be
fixed by the Board of Directors or the President. If this date shall fall upon a
legal holiday at the place of the meeting, then such meeting shall be held on
the next succeeding business day at the same hour. If no annual meeting is held
in accordance with the foregoing provisions, the Board of Directors shall cause
the meeting to be held as soon thereafter as convenient. If no annual meeting is
held in accordance with the foregoing provisions, a special meeting may be held
in lieu of the annual meeting, and any action taken at that special meeting
shall have the same effect as if it had been taken at the annual meeting, and in
such case all references in these By-Laws to the annual meeting of the
stockholders shall be deemed to refer to such special meeting.

        1.3 Special Meetings. Special meetings of stockholders may be called at
any time by the President, the Board of Director or the holders of a majority of
the outstanding shares of the Common Stock. Business transacted at any special
meeting of stockholders shall be limited to matters relating to the purpose or
purposes stated in the notice of meeting.

        1.4 Notice of Meetings. Except as otherwise provided by law, written
notice of each meeting of stockholders, whether annual or special, shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting. The notices of all meetings
shall state the place, date and hour of the meeting. The notice of a special
meeting shall state, in addition, the purpose or purposes for which the meeting
is called. If mailed, notice is given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation. The notice of any meeting of stockholders may be
delivered via facsimile transmission, telegram or telex. If such notice is
delivered via facsimile transmission, telegram or telex, notice shall be deemed
given at the time such transmission is sent.

        1.5 Voting List. The officer who has charge of the stock ledger of the
corporation shall prepare, at least ten days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior

<PAGE>

to the meeting, at a place within the city where the meeting is to be held. The
list shall also be produced and kept at the time and place of the meeting during
the whole time of the meeting, and may be inspected by any stockholder who is
present.

        1.6 Quorum. Except as otherwise provided by law, the Certificate of
Incorporation or these By-Laws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business.

        1.7 Adjournments. Any meeting of stockholders may be adjourned to any
other time and to any other place at which a meeting of stockholders may be held
under these By-Laws by the stockholders present or represented at the meeting
and entitled to vote, although less than a quorum, or, if no stockholder is
present, by any officer entitled to preside at or to act as Secretary of such
meeting. It shall not be necessary to notify any stockholder of any adjournment
of less than 30 days if the time and place of the adjourned meeting are
announced at the meeting at which adjournment is taken, unless after the
adjournment a new record date is fixed for the adjourned meeting. At the
adjourned meeting, the corporation may transact any business which might have
been transacted at the original meeting.

      1.8 Voting and Proxies. Each stockholder shall have one vote for each
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
in the Certificate of Incorporation. Each stockholder of record entitled to vote
at a meeting of stockholders, or to express consent or dissent to corporate
action in writing without a meeting, may vote or express such consent or dissent
in person or may authorize another person or persons to vote or act for him by
written proxy executed by the stockholder or his authorized agent and delivered
to the Secretary of the corporation. No such proxy shall be voted or acted upon
after three years from the date of its execution, unless the proxy expressly
provides for a longer period.

      1.9 Action at Meeting. When a quorum is present at any meeting, the
holders of a majority of the stock present or represented and voting on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of a majority of the
stock of that class present or represented and voting on a matter) shall decide
any matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these By-Laws. Any election by stockholders shall be determined
by a plurality of the votes cast by the stockholders entitled to vote at the
election.

      1.10 Action without Meeting. Any action required or permitted to be taken
at any annual or special meeting of stockholders of the corporation may be taken
without a meeting, without prior notice and without a vote, if an unanimous
consent in writing, setting forth the action so taken, is signed by all of the
holders of outstanding stock.

                              ARTICLE 2 - DIRECTORS

      2.1 General Powers. The business and affairs of the corporation shall be
managed by or under the direction of a Board of Directors, who may exercise all
of the powers of the corporation except as otherwise provided by law, the
Certificate of Incorporation or these By-Laws. In the event of a vacancy in the
Board of Directors, the remaining directors, except as otherwise provided by
law, may exercise the powers of the full Board until the vacancy is filled.

      2.2 Number and Classes. The number of directors which shall constitute the
whole Board of Directors shall be five. The number of directors may be decreased
at any time and from time to time either by the stockholders or by a majority of
the directors then in office, but only to eliminate vacancies existing by reason
of the death, resignation, removal or expiration of the term of one of more
directors. Unless otherwise provided in the Certificate of Incorporation, the
Board of Directors shall divide the directors into three classes, which shall be
as equal in number as possible; and, when the number of directors is changed,
shall determine the class or classes to which the increased or decreased number
of directors shall be apportioned, which shall be done so as to maintain as
equal a number of directors in each class as possible; provided, however, that
no decrease in the number of directors shall affect the term of any director
then in office.

      2.3 Tenure, Election and Qualification. The directors shall be elected at
the annual meeting of stockholders by such stockholders as have the right to
vote on such election. At each annual meeting of stockholders, directors elected
to succeed those whose terms are expiring shall be elected for a term of office
expiring at the annual meeting of stockholders held in the third year following
their election and until their respective successors are elected and qualified,
or until such director's earlier death, resignation or removal. Directors need
not be stockholders of the corporation.

      2.4 Enlargement of the Board. The number of directors may be increased at
any time and from time to time by affirmative vote of the holders of a majority
of the shares of the Corporation's Common Stock and the holders of a majority of
the shares of the Corporation's Preferred Stock, with each of the Common Stock
and the Preferred Stock voting as a separate class. For purposes of these
By-Laws, unless required otherwise by Delaware law or unless specified otherwise
in the Corporation's Certificate of Incorporation, all shares of the
Corporation's Preferred Stock will vote together as a single class, irrespective
of the number of different classes or series of such Preferred Stock that may
from time to time exist.

      2.5 Vacancies. Unless and until filled by the stockholders, any vacancy in
the Board of Directors, however occurring, including a vacancy resulting from an
enlargement of the Board, may be filled by vote of a majority of the directors
then in office, although less than a quorum, or by a sole remaining director. A
director elected


                                      -3-
<PAGE>

to fill a vacancy shall be elected for the unexpired term of his predecessor in
office, and a director chosen to fill a position resulting from an increase in
the number of directors shall hold office until the next annual meeting of
stockholders and until his successor is elected and qualified, or until his
earlier death, resignation or removal.

      2.6 Resignation. Any director may resign by delivering his written
resignation to the corporation at its principal office or to the President or
Secretary. Such resignation shall be effective upon receipt unless it is
specified to be effective at some other time or upon the happening of some other
event.

      2.7 Regular Meetings. Provided that meetings are held at least once during
each of the Company's fiscal quarters, regular meetings of the Board of
Directors may be held without notice at such time and place, either within or
without the State of Delaware, as shall be determined from time to time by the
Board of Directors; provided that any director who is absent when such a
determination is made shall be given notice of the determination. A regular
meeting of the Board of Directors may be held without notice immediately after
and at the same place as the annual meeting of stockholders.

      2.8 Special Meetings. Special meetings of the Board of Directors may be
held at any time and place, within or without the State of Delaware, designated
in a call by any single member of the Board of Directors or by the President of
the Company.

      2.9 Notice of Special Meetings. Notice of any special meeting of directors
shall be given to each director by the Secretary or by the officer or one of the
directors calling the meeting. Notice shall be duly given to each director (i)
by giving notice to such director in person or by telephone at least 48 hours in
advance of the meeting, (ii) by sending a facsimile, telegram or telex, or
delivering written notice by hand, to his last known business or home address at
least 48 hours in advance of the meeting, or (iii) by delivering written notice
to his last known business or home address at least 72 hours in advance of the
meeting by a nationally recognized overnight service (receipt requested). A
notice or waiver of notice of a meeting of the Board of Directors need not
specify the purposes of the meeting.

      2.10 Meetings by Telephone Conference Calls. Directors or any members of
any committee designated by the directors may participate in a meeting of the
Board of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

      2.11 Quorum. A majority of the total number of the whole Board of
Directors shall constitute a quorum at all meetings of the Board of Directors.
In the event one or more of the directors shall be disqualified to vote at any
meeting, then the required quorum shall be reduced by one for each such director
so disqualified; provided, however, that in no case shall less than one-third
(1/3) of the number so fixed constitute a quorum. In the absence of a quorum at
any such meeting, a majority of the directors present may adjourn the meeting
from


                                      -4-
<PAGE>

time to time without further notice other than announcement at the meeting,
until a quorum shall be present.

      2.12 Action at Meeting. At any meeting of the Board of Directors at which
a quorum is present, the vote of a majority of those present shall be sufficient
to take any action, unless a different vote is specified by law, the Certificate
of Incorporation or these By-Laws.

      2.13 Action by Consent. Any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee of the Board of
Directors may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent to the action in writing, and the written
consents are filed with the minutes of proceedings of the Board or committee.

        2.14 Removal. Any one or more or all of the directors may be removed,
with or without cause, by the holders of a majority of the shares then entitled
to vote at an election of directors, except that the directors elected by the
holders of a particular class or series of stock may be removed without cause
only by vote of the holders of a majority of the outstanding shares of such
class or series.

        2.15 Committees. The Board of Directors may, by resolution passed by a
majority of the whole Board, designate one or more committees, each committee to
consist of one or more of the directors of the corporation. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of a committee, the member or
members of the committee present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member. Any such committee, to the extent
provided in the resolution of the Board of Directors and subject to the
provisions of the General Corporation Law of the State of Delaware, shall have
and may exercise all the powers and authority of the Board of Directors in the
management of the business and affairs of the corporation and may authorize the
seal of the corporation to be affixed to all papers which may require it. Each
such committee shall keep minutes and make such reports as the Board of
Directors may from time to time request. Except as the Board of Directors may
otherwise determine, any committee may make rules for the conduct of its
business, but unless otherwise provided by the directors or in such rules, its
business shall be conducted as nearly as possible in the same manner as is
provided in these By-Laws for the Board of Directors.

        2.16 Compensation of Directors. Directors may be paid such compensation
for their services as the Board of Directors may from time to time determine and
Directors shall be reimbursed for expenses (including travel expenses) incurred
to attend meetings. No such payment shall preclude any director from serving the
corporation or any of its parent or subsidiary corporations in any other
capacity and receiving compensation for such service.

        3.5 Resignation and Removal. Any officer may resign by delivering his
written resignation to the corporation at its principal office or to the
President or Secretary. Such resignation shall be effective upon receipt unless
it is specified to be effective at some other time or upon the happening of some
other event.

               Any officer appointed by Board of Directors may be removed at any
time, with or without cause, by vote of a majority of the entire number of
directors then in office.

               Except as the Board of Directors may otherwise determine, no
officer who resigns or is removed shall have any right to any compensation as an
officer for any period following his resignation or removal, or any right to
damages on account of such removal, whether his compensation be by the month or
by the year or otherwise, unless such compensation is expressly provided in a
duly authorized written agreement with the corporation.

        3.6 Vacancies. The Board of Directors may fill any vacancy occurring in
any office for any reason and may, in its discretion, leave unfilled for such
period as it may determine any offices other than those of President, Treasurer
and Secretary. Each such successor shall hold office for the unexpired term of
his predecessor and until his successor is elected and qualified, or until his
earlier death, resignation or removal.

        3.7 Chairman of the Board and Vice-Chairman of the Board. The Board of

Chairman of the Board and shall perform such other duties and possess such other
powers as may from time to time be vested in him by the Board of Directors.

        3.8 President. Unless the Board of Directors otherwise determines, the

shall, subject to the direction of the Board of Directors, have general charge
and supervision of the business of the corporation. Unless otherwise provided by
the Board of Directors, he shall preside at all meetings of the stockholders, if

perform such other duties and shall have such other powers as the Board of
Directors may from time to time prescribe.

        3.9 Vice Presidents. Any Vice President shall perform such duties and

        4.1 Issuance of Stock. Unless otherwise voted by the stockholders and
subject to the provisions of the Certificate of Incorporation, the whole or any
part of any unissued balance of the authorized capital stock of the corporation
or the whole or any part of any unissued balance of the authorized capital stock
of the corporation held in its treasury may be issued, sold, transferred or
otherwise disposed of by vote of the Board of Directors in such manner, for such
consideration and on such terms as the Board of Directors may determine.

        4.2 Certificates of Stock. Every holder of stock of the corporation
shall be entitled to have a certificate, in such form as may be prescribed by
law and by the Board of Directors, certifying the number and class of shares
owned by him in the corporation. Each such certificate shall be signed by, or in

        4.3 Transfers. Except as otherwise established by rules and regulations
adopted by the Board of Directors, and subject to applicable law, shares of
stock may be transferred on the books of the corporation by the surrender to the
corporation or its transfer agent of the certificate representing such shares
properly endorsed or accompanied by a written assignment or power of attorney
properly executed, and with such proof of authority or the authenticity of
signature as the corporation or its transfer agent may reasonably require.
Except as may be otherwise required by law, by the Certificate of Incorporation
or by these By-Laws, the corporation shall be entitled to treat the record
holder of stock as shown on its books as the owner of such stock for all
purposes, including the payment of dividends and the right to vote with respect
to such stock, regardless of any transfer, pledge or other disposition of such
stock until the shares have been transferred on the books of the corporation in
accordance with the requirements of these By-Laws.

        4.4 Lost, Stolen or Destroyed Certificates. The corporation may issue a
new certificate of stock in place of any previously issued certificate alleged
to have been lost, stolen, or destroyed, upon such terms and conditions as the
Board of Directors may prescribe, including the presentation of reasonable
evidence of such loss, theft or destruction and the giving of such indemnity as
the Board of Directors may require for the protection of the corporation or any
transfer agent or registrar.

        4.5 Record Date. The Board of Directors may fix in advance a date as a
record date for the determination of the stockholders entitled to notice of or
to vote at any meeting of stockholders or to express consent (or dissent) to
corporate action in writing without a meeting, or entitled to receive payment of
any dividend or other distribution or allotment of any rights in respect of any
change, conversion or exchange of stock, or for the purpose of any other lawful
action. Such record date shall not be more than 60 nor less than ten days before
the date of such meeting, nor more than 60 days prior to any other action to
which such record date relates.

               If no record date is fixed, the record date for determining
stockholders entitled to notice of or to vote at a meeting of stockholders shall
be at the close of business on the day before the day on which notice is given,
or, if notice is waived, at the close of business on the day before the day on
which the meeting is held. The record date for determining stockholders entitled
to express consent to corporate action in writing without a meeting, when no
prior action by the Board of Directors is necessary, shall be the day on which
the first written consent is expressed. The record date for determining
stockholders for any other purpose shall be at the close of business on the day
on which the Board of Directors adopts the resolution relating to such purpose.

               A determination of stockholders of record entitled to notice of
or to vote at a meeting of stockholders shall apply to any adjournment of the
meeting; provided, however, that the Board of Directors may fix a new record
date for the adjourned meeting.

                           ARTICLE 5 - INDEMNIFICATION

        5.1 Indemnification in Actions, Suits or Proceedings Other Than Those by
or in the Right of the Corporation. (a) The Corporation shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (whether civil,
criminal, administrative or investigative) by reason of the fact that such
person is or was a director or officer of the Corporation, or is or was serving
at the request of the Corporation as a director or officer of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding, if such person acted in good
faith and in a manner which such person reasonably believed to be in or not
opposed to the best interests of the Corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe that such
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which such person reasonably believed to
be in or not opposed to the best interests of the Corporation, and, with respect
to any criminal action or proceeding, had reasonable cause to believe that such
conduct was unlawful.

           (b) The Corporation may indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (whether civil, criminal, administrative or investigative) by
reason of the fact that such person is or was an employee or agent of the
Corporation, or is or was serving at the request of the Corporation as an
employee or agent of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding, if such person acted in good faith and in a manner which such person
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that such conduct was unlawful. The termination of
any action, suit or proceeding by judgment, order, settlement, conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which such
person reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that such conduct was unlawful.

        5.2 Indemnification in Actions, Suits or Proceedings by or in the Right
of the Corporation. (a) The Corporation shall indemnify any person who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding by or in the right of the Corporation to
procure a judgment in its favor by reason of the fact that such person is or was
a director or officer of the Corporation, or is or was serving at the request of
the Corporation as a director of officer of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise, against
expenses (including


                                      -10-
<PAGE>

attorneys' fees) actually and reasonably incurred by such person in connection
with the defense or settlement of such action or suit if such person acted in
good faith and in a manner which such person reasonably believed to be in or not
opposed to the best interest of the Corporation. No such indemnification shall
be made in respect of any claim, issue or matter as to which such person shall
have been adjudged to be liable to the Corporation unless and only to the extent
that the court in which such action or suit was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which such court shall deem proper.

           (b) The Corporation may indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding by or in the right of the Corporation to procure a judgment
in its favor by reason of the fact that such person is or was an employee or
agent of the Corporation, or is or was serving at the request of the Corporation
as an employee or agent of another corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise, against expenses (including
attorneys' fees) actually and reasonably incurred by such person in connection
with the defense or settlement of such action or suit if such person acted in
good faith and in a manner which such person reasonably believed to be in or not
opposed to the best interests of the Corporation. No such indemnification shall
be made in respect of any claim, issue or matter as to which such person shall
have been adjudged to be liable to the Corporation unless and only to the extent
that the court in which such action or suit was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which such court shall deem proper.

        5.3 Authorization of Indemnification. Any indemnification under this
Article 5 shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee or agent is proper in the circumstances because such person or persons
have met the applicable standard of conduct set forth in Sections 5.1 and 5.2
hereof. Such determination shall be made (i) by a majority vote of the directors
who are not parties to such action, suit or proceeding, even though less than a
quorum, or (ii) if there are no such directors, or if such directors so direct,
by independent legal counsel in a written opinion, or (iii) by the stockholders.

        5.4 Advancement of Expenses. The Corporation shall, if so requested by
an officer or director, advance expenses (including attorneys' fees) incurred by
a director or officer in advance of the final disposition of such action, suit
or proceeding upon the receipt of an undertaking by or on behalf of the director
of officer to repay such amount if it shall ultimately be determined that such
director or officer is not entitled to indemnification.

               The Corporation may advance expenses (including attorneys' fees)
incurred by an employee or agent in advance of the final disposition of such
action, suit or proceeding upon such terms and conditions, if any, as the Board
of Directors deems appropriate.

Assistant Secretary, or a temporary Secretary as to any action taken by the
stockholders, directors, a committee or any officer or representative of the
corporation shall as to all persons who rely on the certificate in good faith be

Certificate of Incorporation shall be deemed to refer to the Certificate of
Incorporation of the corporation, as amended and in effect from time to time.

between the Corporation and one or more of the directors or officers, or between
the Corporation and any other corporation, partnership, association, another

               Common or interested directors may be counted in determining the
presence of a quorum at a meeting of the Board of Directors or of a committee
which authorizes the contract or transaction.

    SECTION 3.2   ANNUAL MEETING.

          (a) The annual meeting of the stockholders of the corporation, for the
purpose of election of Directors and for such other business as may lawfully
come before it, shall be held on such date and at such time as may be designated
from time to time by the Board of Directors.

          (b) At an annual meeting of the stockholders, only such business shall
be conducted as shall have been properly brought before the meeting. To be
properly brought before an annual meeting, business must be: (A) specified in
the notice of meeting (or any supplement thereto) given by or at the direction
of the Board of Directors; (B) otherwise properly brought before the meeting by
or at the direction of the Board of Directors; or (C) otherwise properly brought
before the meeting by a stockholder. For business to be properly brought before
an annual meeting by a stockholder, the stockholder must have given timely
notice thereof in writing to the Secretary of the corporation. To be timely, a
stockholder's notice must be delivered to or mailed and received by the
Secretary of the corporation not later than the close of business on the
ninetieth (90th) day, and no earlier than the close of business on the one
hundred twentieth (120th) day, prior to the first anniversary of the date of the
proxy statement delivered to stockholders in connection with the preceding
year's annual meeting; provided, however, that if either (i) the date of the
annual meeting is advanced more than thirty (30) days or delayed (other than as
a result of adjournment) more than sixty (60) days from such an anniversary date
or (ii) no proxy statement was delivered to stockholders in connection with the
preceding year's annual meeting, notice by the stockholder to be timely must be
so delivered not earlier than the close of business on the one hundred twentieth
(120th) day prior to such annual meeting and not later than the close of
business on the later of the ninetieth (90th) day prior to such annual meeting
or the close of business on the tenth (10th) day following the day on which
public announcement of the date of such meeting is first made by the
corporation. To be in proper form, a stockholder's notice to the Secretary shall
set forth as to each matter the stockholder proposes to bring before the annual
meeting:

               (i) a brief description of the business desired to be brought
          before the annual meeting and the reasons for conducting such business
          at the annual meeting;

               (ii) a representation that the stockholder is a holder of record
          of stock of the corporation entitled to vote at such meeting and, if
          applicable, intends to appear in person or by proxy at the meeting to
          nominate the person or persons specified in the notice or introduce
          the business specified in the notice;

               (iii) the name and address, as they appear on the corporation's
          books, of the stockholder proposing such business;

               (iv) the class and number of shares of the corporation which are
          beneficially owned by the stockholder;

               (v) any material interest of the stockholder in such business;
          and


                                       2
<PAGE>

               (vi) any other information that is required to be provided by the
          stockholder pursuant to Regulation 14A under the Securities Exchange
          Act of 1934, as amended (the "Exchange Act"), in such stockholder's
          capacity as a proponent of a stockholder proposal.

          The chairman of the meeting shall determine whether any business
proposed to be transacted by the stockholders has been properly brought before
the meeting and, if any proposed business has not been properly brought before
the meeting, the chairman shall declare that such proposed business shall not be
presented for stockholder action at the meeting. For purposes of this Section
3.2, "public announcement" shall mean disclosure in a press release reported by
the Dow Jones News Service, Associated Press or comparable national news service
or in a document publicly filed by the corporation with the Securities and
Exchange Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act.
Notwithstanding any provision in this Section 3.2 to the contrary, requests for
inclusion of proposals in the corporation's proxy statement made pursuant to
Rule 14a-8 under the Exchange Act shall be deemed to have been delivered in a
timely manner if delivered in accordance with such Rule. Notwithstanding
compliance with the requirements of this Section 3.2, the chairman presiding at
any meeting of the stockholders may, in his sole discretion, refuse to allow a
stockholder or stockholder representative to present any proposal which the
corporation would not be required to include in a proxy statement under any rule
promulgated by the Securities and Exchange Commission.

          (c) Only persons who are nominated in accordance with the procedures
set forth in this paragraph shall be eligible for election as Directors.
Nominations of persons for election to the Board of Directors of the corporation
may be made at a meeting of stockholders by or at the direction of the Board of
Directors or by any stockholder of the corporation entitled to vote in the
election of Directors at the meeting who complies with the notice procedures set
forth in this paragraph. Such nominations, other than those made by or at the
direction of the Board of Directors, shall be made pursuant to timely notice in
writing to the Secretary of the corporation in accordance with the provisions of
paragraph (b) of this Section 3.2. Such stockholder's notice shall set forth (i)
as to each person, if any, whom the stockholder proposes to nominate for
election or re-election as a Director: (A) the name, age, business address and
residence address of such person; (B) the principal occupation or employment of
such person; (C) the class and number of shares of the corporation which are
beneficially owned by such person; (D) a description of all arrangements or
understandings between the stockholder and each nominee and any other person or
persons (naming such person or persons) pursuant to which the nominations are to
be made by the stockholder; and (E) any other information relating to such
person that is required to be disclosed in solicitations of proxies for election
of Directors, or is otherwise required in each case pursuant to Regulation 14A
under the 1934 Act (including without limitation such person's written consent
to being named in the proxy statement, if any, as a nominee and to serving as a
Director if elected); and (ii) as to such stockholder giving notice, the
information required to be provided pursuant to paragraph (b) of this Section
3.2. At the request of the Board of Directors, any person nominated by a
stockholder for election as a Director shall furnish to the Secretary of the
corporation that information required to be set forth in the stockholder's
notice of nomination which pertains to the nominee. No person shall be eligible
for election as a Director of the corporation unless nominated in accordance
with the procedures set forth in this paragraph. The chairman of the meeting
shall, if the facts warrant, determine and declare at the meeting that a
nomination was not made in accordance with the


                                       3
<PAGE>

procedures prescribed by these Bylaws, and if the chairman should so determine,
the chairman shall so declare at the meeting, and the defective nomination shall
be disregarded.

     SECTION 3.3 SPECIAL MEETINGS.

          (a) Special meetings of the stockholders of the corporation may only
be called, for any purpose or purposes, by the President of the Board of
Directors pursuant to a resolution adopted by a majority of the total number of
authorized Directors (whether or not there exist any vacancies in previously
authorized directorships at the time any such resolution is presented to the
Board of Directors for adoption).

          (b) No business may be transacted at such special meeting otherwise
than specified in the resolution calling for the meeting. The Board of Directors
shall determine the time and place of such special meeting, which shall be held
not less than ninety (90) nor more than one hundred twenty (120) days after the
date of the receipt of the request. Upon determination of the time and place of
the meeting, notice shall be given to the stockholders entitled to vote, in
accordance with the provisions of Section 3.4 of these Bylaws. Nothing contained
in this paragraph (b) shall be construed as limiting, fixing or affecting the
time when a meeting of stockholders may be held.

     SECTION 3.4 NOTICE OF MEETINGS. Except as otherwise provided by law or the
certificate of incorporation of the corporation, as the same may be amended or
restated from time to time and including any certificates of designation
thereunder (hereinafter, the "Certificate of Incorporation"), written notice of
each meeting of stockholders shall be given not less than ten (10) nor more than
sixty (60) days before the date of the meeting to each stockholder entitled to
vote at such meeting, such notice to specify the place, date, time and purpose
or purposes of the meeting. Notice of any meeting of stockholders may be waived
in writing, signed by the person entitled to notice thereof, either before or
after such meeting, and will be waived by any stockholder by his attendance
thereat in person or by proxy, except when the stockholder attends a meeting for
the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Any stockholder so waiving notice of such meeting shall be bound by
the proceedings of any such meeting in all respects as if due notice thereof had
been given.

     SECTION 3.5 QUORUM. At all meetings of stockholders, except where otherwise
provided by statute or by the Certificate of Incorporation, or by these Bylaws,
the presence, in person or by duly authorized proxy, of the holders of a
majority of the outstanding shares of stock entitled to vote shall constitute a
quorum for the transaction of business. In the absence of a quorum, any meeting
of stockholders may be adjourned, from time to time, either by the chairman of
the meeting or by vote of the holders of a majority of the shares represented
thereat, but no other business shall be transacted at such meeting. The
stockholders present at a duly called or convened meeting, at which a quorum is
present, may continue to transact business until adjournment, notwithstanding
the withdrawal of enough stockholders to leave less than a quorum. Except as
otherwise provided by law, the Certificate of Incorporation or these Bylaws, all
actions taken by the holders of a majority of the votes cast, excluding
abstentions, at any meeting at which a quorum is present shall be valid and
binding upon the corporation; provided, however, that Directors shall be elected
by a plurality of the votes of the shares present in person


                                       4
<PAGE>

or represented by proxy at the meeting and entitled to vote on the election of
Directors. Where a separate vote by a class or classes is required, a majority
of the outstanding shares of such class or classes, present in person or
represented by proxy, shall constitute a quorum entitled to take action with
respect to that vote on that matter and the affirmative vote of the majority
(plurality, in the case of the election of Directors) of shares of such class or
classes present in person or represented by proxy at the meeting shall be the
act of such class.

     SECTION 3.6 ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS. Any meeting of
stockholders, whether annual or special, may be adjourned from time to time
either by the chairman of the meeting or by the vote of a majority of the shares
casting votes, excluding abstentions. When a meeting is adjourned to another
time or place, notice need not be given of the adjourned meeting if the time and
place thereof are announced at the meeting at which the adjournment is taken. At
the adjourned meeting, the corporation may transact any business which might
have been transacted at the original meeting. If the adjournment is for more
than thirty (30) days or if after the adjournment a new record date is fixed for
the adjourned meeting, a notice of the adjourned meeting shall be given to each
stockholder of record entitled to vote at the meeting.

     SECTION 3.7 VOTING RIGHTS. For the purpose of determining those
stockholders entitled to vote at any meeting of the stockholders, except as
otherwise provided by law, only persons in whose names shares stand on the stock
records of the corporation on the record date, as provided in Section 7.5 of
these Bylaws, shall be entitled to vote at any meeting of stockholders. Every
person entitled to vote or execute consents shall have the right to do so either
in person or by an agent or agents authorized by a written proxy executed by
such person or his duly authorized agent, which proxy shall be filed with the
Secretary at or before the meeting at which it is to be used. An agent so
appointed need not be a stockholder. No proxy shall be voted after three (3)
years from its date of creation unless the proxy provides for a longer period.
Elections of Directors need not be by written ballot, unless otherwise provided
in the Certificate of Incorporation.

     SECTION 3.8 JOINT OWNERS OF STOCK. If shares or other securities having
voting power stand of record in the names of two (2) or more persons, whether
fiduciaries, members of a partnership, joint tenants, tenants in common, tenants
by the entirety, or otherwise, or if two (2) or more persons have the same
fiduciary relationship respecting the same shares, unless the Secretary is given
written notice to the contrary and is furnished with a copy of the instrument or
order appointing them or creating the relationship wherein it is so provided,
their acts with respect to voting shall have the following effect: (a) if only
one (1) votes, his act binds all; (b) if more than one (1) votes, the act of the
majority so voting binds all; or (c) if more than one (1) votes, but the vote is
evenly split on any particular matter, each faction may vote the securities in
question proportionally, or may apply to the Delaware Court of Chancery for
relief as provided in the Delaware General Corporation Law, Section 217(b). If
the instrument filed with the Secretary shows that any such tenancy is held in
unequal interests, a majority or even-split for the purpose of clause (c) shall
be a majority or even-split in interest.

     SECTION 3.9 LIST OF STOCKHOLDERS. The Secretary shall prepare and make, at
least ten (10) days before every meeting of stockholders, a complete list of the
stockholders entitled to vote at said meeting, arranged in alphabetical order,
showing the address of each stockholder and


                                       5
<PAGE>

the number of shares registered in the name of each stockholder. Such list shall
be open to the examination of any stockholder, for any purpose germane to the
meeting, during ordinary business hours, for a period of at least ten (10) days
prior to the meeting, either at a place within the city where the meeting is to
be held, which place shall be specified in the notice of the meeting, or, if not
specified, at the place where the meeting is to be held. The list shall be
produced and kept at the time and place of meeting during the whole time thereof
and may be inspected by any stockholder who is present.

     SECTION 3.10 NO ACTION WITHOUT MEETING. The stockholders of the corporation
may not take action by written consent without a meeting and must take any
actions at a duly called annual or special meeting.

     SECTION 3.11 ORGANIZATION.

          (a) At every meeting of stockholders, unless another officer of the
corporation has been appointed by the Board of Directors, the Chairman of the
Board of Directors, or, if a Chairman has not been appointed, is absent, or
designates the next senior officer present to so act, the President, or, if the
President is absent, the most senior Vice President present, or, in the absence
of any such officer, a chairman of the meeting chosen by a majority in interest
of the stockholders entitled to vote, present in person or by proxy, shall act
as chairman. The Secretary, or, in his absence, an Assistant Secretary directed
to do so by the President, shall act as secretary of the meeting.

          (b) The Board of Directors of the corporation shall be entitled to
make such rules or regulations for the conduct of meetings of stockholders as it
shall deem necessary, appropriate or convenient. Subject to such rules and
regulations of the Board of Directors, if any, the chairman of the meeting shall
have the right and authority to prescribe such rules, regulations and procedures
and to do all such acts as, in the judgment of such chairman, are necessary,
appropriate or convenient for the proper conduct of the meeting, including,
without limitation, establishing an agenda or order of business for the meeting,
rules and procedures for maintaining order at the meeting and the safety of
those present, limitations on participation in such meeting to stockholders of
record of the corporation and their duly authorized and constituted proxies and
such other persons as the chairman shall permit, restrictions on entry to the
meeting after the time fixed for the commencement thereof, limitations on the
time allotted to questions or comments by participants and regulation of the
opening and closing of the polls for balloting on matters which are to be voted
on by ballot. Unless and to the extent determined by the Board of Directors or
the chairman of the meeting, meetings of stockholders shall not be required to
be held in accordance with rules of parliamentary procedure.

                                    DIRECTORS

     SECTION 4.1 NUMBER AND TERM OF OFFICE; CLASSIFICATION.

          (a) The number of directors which shall constitute the whole Board of
Directors shall be determined from time to time by the Board of Directors
(provided that no decrease in the number of directors which would have the
effect of shortening the term of an incumbent director may be made by the Board
of Directors), provided that the number of directors shall be not less than one
(1). At each annual meeting of stockholders, Directors of the corporation shall
be elected to hold office until the expiration of the term for which they are
elected, and until their successors have been duly elected and qualified or
until such Director's earlier death, resignation or due removal; except that if
any such election shall not be so held, such election shall take place at a
stockholders' meeting called and held in accordance with the Delaware General
Corporation Law. Directors need not be stockholders unless so required by the
Certificate of Incorporation. If, for any reason, the Directors shall not have
been elected at an annual meeting, they may be elected as soon thereafter as
convenient at a special meeting of the stockholders called for that purpose in
the manner provided in these Bylaws.

          (b) The Board of Directors shall be divided into three classes as
nearly equal in size as is practicable, hereby designated as Class I, Class II,
and Class III, respectively. Directors shall be assigned to each class in
accordance with a resolution or resolutions adopted by the Board of Directors.
At the first annual meeting of stockholders following the date hereof, the term
of office of the Class I directors shall expire, and Class I directors shall be
elected for a full term of three years. At the second annual meeting of
stockholders following the date hereof, the term of office of the Class II
directors shall expire, and Class II directors shall be elected for a full term
of three years. At the third annual meeting of stockholders following the date
hereof, the term of office of the Class III directors shall expire, and Class
III directors shall be elected for a full term of three years. At each
succeeding annual meeting of stockholders, directors shall be elected for a full
term of three years to succeed the directors of the class whose terms expire at
such annual meeting. If the number of directors is hereafter changed, any newly
created directorship or decrease in directorships shall be so apportioned among
the classes as to make all classes as nearly equal in number as is practicable.

     SECTION 4.2 POWERS. The powers of the corporation shall be exercised, its
business conducted and its property controlled by the Board of Directors, except
as may be otherwise provided by statute or by the Certificate of Incorporation.

     SECTION 4.3 VACANCIES. Vacancies occurring on the Board of Directors may be
filled by vote of a majority of the remaining members of the Board of Directors,
although less than a quorum. Each Director so elected shall hold office for the
unexpired portion of the term of the Director or newly created directorship
whose place shall be vacant and until his or her successor shall have been duly
elected and qualified or until such Director's earlier death, resignation or due
removal. A vacancy in the Board of Directors shall be deemed to exist under this
Section 4.3 in the case of (i) the death, removal or resignation of any
Director; (ii) an increase in the authorized number of Directors pursuant to
Section 4.1(a) above; or (iii) if the


                                       7
<PAGE>

stockholders fail at any meeting of stockholders at which Directors are to be
elected (including any meeting referred to in Section 4.6 below) to elect the
number of Directors then constituting the whole Board of Directors.

     SECTION 4.4 RESIGNATION. Any Director may resign at any time by delivering
his or her written resignation to the Secretary, such resignation to specify
whether it will be effective at a particular time, upon receipt by the Secretary
or at the pleasure of the Board of Directors. If no such specification is made,
it shall be deemed effective at the pleasure of the Board of Directors. When one
or more Directors shall resign from the Board of Directors, effective at a
future date, a majority of the Directors then in office, including those who
have so resigned, shall have power to fill such vacancy or vacancies, the vote
thereon to take effect when such resignation or resignations shall become
effective, and each Director so chosen shall hold office for the unexpired
portion of the term of the Director whose place shall be vacated and until his
successor shall have been duly elected and qualified.

     SECTION 4.5 REMOVAL. At a special meeting of stockholders called for such
purpose and in the manner provided herein, subject to any limitations imposed by
law or the Certificate of Incorporation, the Board of Directors, or any
individual Director, may only be removed from office for cause, and a new
Director or Directors shall be elected by a vote of stockholders holding a
majority of the outstanding shares entitled to vote at an election of Directors.

     SECTION 4.6 MEETINGS.

          (a) ANNUAL MEETINGS. Unless the Board shall determine otherwise, the
annual meeting of the Board of Directors shall be held immediately before or
after the annual meeting of stockholders and at the place where such meeting is
held. No notice of an annual meeting of the Board of Directors shall be
necessary and such meeting shall be held for the purpose of electing officers
and transacting such other business as may lawfully come before it.

          (b) REGULAR MEETINGS. Except as hereinafter otherwise provided,
regular meetings of the Board of Directors shall be held in the principal
executive offices of the corporation. Unless otherwise restricted by the
Certificate of Incorporation, regular meetings of the Board of Directors may
also be held at any place within or without the State of Delaware which has been
designated by resolution of the Board of Directors or the written consent of all
directors.

          (c) SPECIAL MEETINGS. Unless otherwise restricted by the Certificate
of Incorporation, and subject to the notice requirements contained herein,
special meetings of the Board of Directors may be held at any time and place
within or without the State of Delaware whenever called by the Chairman of the
Board, the President or any two of the Directors.

          (d) TELEPHONE MEETINGS. Any member of the Board of Directors, or of
any committee thereof, may participate in a meeting by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and participation in a meeting
by such means shall constitute presence in person at such meeting.


                                       8
<PAGE>

          (e) NOTICE OF MEETINGS. Written notice of the time and place of all
special meetings of the Board of Directors shall be given at least one (1) day
before the date of the meeting. Such notice need not state the purpose or
purposes of such meeting, except as may otherwise be required by law or provided
for in the Certificate of Incorporation or these Bylaws. Notice of any meeting
may be waived in writing at any time before or after the meeting and will be
deemed waived by any Director by attendance thereat, except when the Director
attends the meeting solely for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened.

          (f) WAIVER OF NOTICE. The transaction of all business at any meeting
of the Board of Directors, or any committee thereof, however called or noticed,
or wherever held, shall be as valid as though had at a meeting duly held after
regular call and notice, if a quorum be present and if, either before or after
meeting, each of the Directors not present shall sign a written waiver of
notice, or a consent to holding such meeting, or an approval of the minutes
thereof. All such waivers, consents or approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.

     SECTION 4.7 QUORUM AND VOTING.

          (a) Unless the Certificate of Incorporation requires a greater number
and except with respect to indemnification questions arising under Article XI
hereof, for which a quorum shall be one-third of the exact number of Directors
fixed from time to time in accordance with Section 4.1 hereof, but not less than
one (1), a quorum of the Board of Directors shall consist of a majority of the
exact number of directors fixed from time to time in accordance with Section 4.1
of these Bylaws, but not less than one (1); provided, however, at any meeting
whether a quorum be present or otherwise, a majority of the Directors present
may adjourn from time to time until the time fixed for the next regular meeting
of the Board of Directors, without notice other than by announcement at the
meeting.

          (b) At each meeting of the Board of Directors at which a quorum is
present, all questions and business shall be determined by a vote of the
majority of the Directors present, unless a different vote is required by law,
the Certificate of Incorporation or these Bylaws.

     SECTION 4.8 ACTION WITHOUT MEETING. Unless otherwise restricted by the
Certificate of Incorporation or these Bylaws, any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
may be taken without a meeting, if all members of the Board of Directors or
committee, as the case may be, consent thereto in writing, and such writing or
writings are filed with the minutes of proceedings of the Board of Directors or
committee.

     SECTION 4.9 FEES AND COMPENSATION. Directors shall be entitled to such
compensation for their services as may be approved by the Board of Directors,
including, if so approved, by resolution of the Board of Directors, a fixed sum
and expenses of attendance, if any, for attendance at each regular or special
meeting of the Board of Directors and at any meeting of a committee of the Board
of Directors. Nothing herein contained shall be construed to preclude any
Director from serving the corporation in any other capacity as an officer,
agent, employee, or otherwise and receiving compensation therefor.

     SECTION 4.10 COMMITTEES.

          (a) EXECUTIVE COMMITTEE. The Board of Directors may by resolution
passed by a majority of the whole Board of Directors appoint an Executive
Committee to consist of one (1) or more members of the Board of Directors. The
Executive Committee, to the extent permitted by law and specifically granted by
the Board of Directors, shall have, and may exercise when the Board of Directors
is not in session, all powers of the Board of Directors in the management of the
business and affairs of the corporation except such committee shall not have the
power or authority to amend the Certificate of Incorporation, to adopt an
agreement of merger or consolidation, to recommend to the stockholders the sale,
lease or exchange of all or substantially all of the corporation's property and
assets, to recommend to the stockholders of the corporation a dissolution of the
corporation or a revocation of a dissolution, or to amend these Bylaws.

          (b) OTHER COMMITTEES. The Board of Directors may, by resolution passed
by a majority of the whole Board of Directors, from time to time appoint such
other committees as may be permitted by law. Such other committees appointed by
the Board of Directors shall consist of one (1) or more members of the Board of
Directors and shall have such powers and perform such duties as may be
prescribed by the resolution or resolutions creating such committees, but in no
event shall such committee have the powers denied to the Executive Committee in
these Bylaws.

          (c) TERM. Each member of a committee of the Board of Directors shall
serve a term on the committee coexistent with such member's term on the Board of
Directors. The Board of Directors, subject to the provisions of paragraphs (a)
and (b) of this Section 4.10 may at any time increase or decrease the number of
members of a committee or terminate the existence of a committee. The membership
of a committee member shall terminate on the date of his or her death or
voluntary resignation from the committee or from the Board of Directors. The
Board of Directors may at any time for any reason remove any individual
committee member and the Board of Directors may fill any committee vacancy
created by death, resignation, removal or increase in the number of members of
the committee. The Board of Directors may designate one or more Directors as
alternate members of any committee, who may replace any absent or disqualified
member at any meeting of the committee, and, in addition, in the absence or
disqualification of any member of a committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of any such absent or disqualified
member.

          (d) MEETINGS. Unless the Board of Directors shall otherwise provide,
regular meetings of the Executive Committee or any other committee appointed
pursuant to this Section 4.10 shall be held at such times and places as are
determined by the Board of Directors, or by any such committee, and when notice
thereof has been given to each member of such committee, no further notice of
such regular meetings need be given thereafter. Special meetings of any such

place of such special meeting given in the manner provided for the giving of

Directors of the time and place of special meetings of the Board of Directors.
Notice of any special meeting of any committee may be waived in writing at any
time before or after the meeting and will be waived by any Director by
attendance thereat, except when the Director attends such special meeting solely

transaction of any business because the meeting is not lawfully called or
convened. A majority of the authorized number of members of any such committee
shall constitute a quorum for the transaction of business, and the act of a
majority of those present at any meeting at which a quorum is present shall be
the act of such committee.

the Vice Chairman is not present, a chairman chosen by a majority of the
Directors present shall act as chairman of such meeting. The Secretary of the
corporation or, in the absence of the Secretary, any person appointed by the
Chairman shall act as secretary of the meeting.

evidences of indebtedness of the corporation, and other corporate instruments or
documents requiring the corporate seal, and


                                       14
<PAGE>

certificates of shares of stock owned by the corporation, shall be executed,
signed or endorsed by the Chairman of the Board of Directors, the President,
Chief Executive Officer or any executive Vice President and if any be
designated, Chief Financial Officer, Treasurer, Assistant Secretary or Assistant
Treasurer, and upon the authority conferred by the Board of Directors, President
or Chief Executive Officer, any non-executive Vice President, and by the

or authority to bind the corporation by any contract or engagement or to pledge
its credit or to render it liable for any purpose or for any amount.

     SECTION 6.2 VOTING OF SECURITIES OWNED BY THE CORPORATION. All stock and
other securities of other corporations owned or held by the corporation for

                                 SHARES OF STOCK

     SECTION 7.1 FORM AND EXECUTION OF CERTIFICATES. Certificates for the shares
of stock of the corporation shall be in such form as is consistent with the
Certificate of Incorporation and applicable law. Every holder of stock in the
corporation shall be entitled to have a certificate signed by or in the name of
the corporation by the Chairman or Vice Chairman of the Board of Directors, the
Chief Executive Officer, the President or any executive Vice President and by
the Secretary or an Assistant Secretary or the Treasurer or an Assistant
Treasurer, certifying the number of shares and the class or series owned by him
in the corporation. Where such certificate is countersigned by a transfer agent
other than the corporation or its employee, or by a registrar other than the
corporation or its employee, any other signature on the certificate may be a
facsimile. In case any officer, transfer agent, or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent, or registrar before such certificate is
issued, it may be issued with the same effect as if he were such officer,
transfer agent, or registrar at the date of issue.


                                       15
<PAGE>

     SECTION 7.2 LOST CERTIFICATES. A new certificate or certificates shall be
issued in place of any certificate or certificates theretofore issued by the
corporation alleged to have been lost, stolen, or destroyed, upon the making of
an affidavit of that fact by the person claiming the certificate of stock to be
lost, stolen, or destroyed. The corporation may require, as a condition
precedent to the issuance of a new certificate or certificates, the owner of
such lost, stolen, or destroyed certificate or certificates, or his legal
representative, to advertise the same in such manner as it shall require or to
give the corporation a surety bond in such form and amount as it may direct as
indemnity against any claim that may be made against the corporation with
respect to the certificate alleged to have been lost, stolen or destroyed.

     SECTION 7.3 TRANSFERS.

          (a) Transfers of record of shares of stock of the corporation shall be
made only on its books by the holders thereof, in person or by attorney duly
authorized and upon the surrender of a properly endorsed certificate or
certificates for a like number of shares. Upon surrender to the corporation or a
transfer agent of the corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer, it shall be the duty of the corporation to issue a new certificate to
the person entitled thereto, cancel the old certificate and record the
transaction upon its books. The Board of Directors shall have the power and
authority to make all such other rules and regulations as they may deem
expedient concerning the issue, transfer and registration or the replacement of
certificates for shares of capital stock of the corporation.

          (b) The corporation shall have power to enter into and perform any
agreement with any number of stockholders of any one or more classes of stock of
the corporation to restrict the transfer of shares of stock of the corporation
of any one or more classes owned by such stockholders in any manner not
prohibited by the Delaware General Corporation Law.

     SECTION 7.4 FIXING RECORD DATES.

          (a) In order that the corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, the Board of Directors may fix, in advance, a record date,
which record date shall not precede the date upon which the resolution fixing
the record date is adopted by the Board of Directors, and which record date
shall not be more than sixty (60) nor less than ten (10) days before the date of
such meeting. If no record date is fixed by the Board of Directors, the record
date for determining stockholders entitled to notice of or to vote at a meeting
of stockholders shall be at the close of business on the day next preceding the
day on which notice is given, or if notice is waived, at the close of business
on the day next preceding the day on which the meeting is held. A determination
of stockholders of record entitled to notice of or to vote at a meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the Board of Directors may fix a new record date for the adjourned meeting.

          (b) In order that the corporation may determine the stockholders
entitled to receive payment of any dividend or other distribution or allotment
of any rights or the stockholders entitled to exercise any rights in respect of
any change, conversion or exchange of stock, or for the purpose of any other
lawful action, the Board of Directors may fix, in advance, a


                                       16
<PAGE>

record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted, and which record date shall be not
more than sixty (60) days prior to such action. If no record date is fixed by
the Board of Directors, the record date for determining stockholders for any
such purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto.

     SECTION 7.5 REGISTERED STOCKHOLDERS. The corporation shall be entitled to
recognize the exclusive right of a person registered on its books as the owner
of shares to receive dividends, and to vote as such owner, and shall not be
bound to recognize any equitable or other claim to or interest in such share or
shares on the part of any other person whether or not it shall have express or
other notice thereof, except as otherwise provided by the laws of Delaware.

                                  ARTICLE VIII

                       OTHER SECURITIES OF THE CORPORATION

     SECTION 8.1 EXECUTION OF OTHER SECURITIES. All bonds, debentures and other
corporate securities of the corporation, other than stock certificates (covered
in Section 7.1), may be signed by the Chairman or Vice Chairman of the Board of
Directors, the Chief Executive Officer, the President or any executive Vice
President, or such other person as may be authorized by the Board of Directors,
and the corporate seal impressed thereon or a facsimile of such seal imprinted
thereon and attested by the signature of the Secretary or an Assistant
Secretary, or the Treasurer or an Assistant Treasurer; provided, however, that
where any such bond, debenture or other corporate security shall be
authenticated by the manual signature of a trustee under an indenture pursuant
to which such bond, debenture or other corporate security shall be issued, the
signatures of the persons signing and attesting the corporate seal on such bond,
debenture or other corporate security may be the imprinted facsimile of the
signatures of such persons. Interest coupons appertaining to any such bond,
debenture or other corporate security, authenticated by a trustee as aforesaid,
shall be signed by the Treasurer or an Assistant Treasurer of the corporation or
such other person as may be authorized by the Board of Directors, or bear
imprinted thereon the facsimile signature of such person. In case any officer
who shall have signed or attested any bond, debenture or other corporate
security, or whose facsimile signature shall appear thereon or on any such
interest coupon, shall have ceased to be such officer before any bond, debenture
or other corporate security so signed or attested shall have been delivered,
such bond, debenture or other corporate security nevertheless may be adopted by
the corporation and issued and delivered as though the person who signed the
same or whose facsimile signature shall have been used thereon had not ceased to
be such officer of the corporation.

                                   ARTICLE IX

                                    DIVIDENDS

     SECTION 9.1 DECLARATION OF DIVIDENDS. Dividends upon the capital stock of
the corporation, subject to the provisions of the Certificate of Incorporation,
if any, may be declared by the Board of Directors pursuant to law at any regular
or special meeting. Dividends may be


                                       17
<PAGE>

paid in cash, in property, or in shares of the capital stock, subject to the
provisions of the Certificate of Incorporation.

     SECTION 9.2 DIVIDEND RESERVE. Before payment of any dividend, there may be
set aside out of any funds of the corporation available for dividends such sum
or sums as the Board of Directors from time to time, in their absolute
discretion, think proper as a reserve or reserves to meet contingencies, or for
equalizing dividends, or for repairing or maintaining any property of the
corporation, or for such other purpose as the Board of Directors shall think
conducive to the interests of the corporation, and the Board of Directors may
modify or abolish any such reserve in the manner in which it was created.

                                   ARTICLE XI

       INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES AND OTHER AGENTS

     SECTION 11.1 DIRECTORS AND EXECUTIVE OFFICERS. The corporation shall
indemnify its Directors and executive officers to the fullest extent not
prohibited by the Delaware General Corporation Law; provided, however, that the
corporation may limit the extent of such indemnification by individual contracts
with its Directors and executive officers; and, provided, further, that the
corporation shall not be required to indemnify any Director or executive officer
in connection with any proceeding (or part thereof) initiated by such person or
any proceeding by such person against the corporation or its Directors,
officers, employees or other agents unless (i) such indemnification is expressly
required to be made by law, (ii) the proceeding was authorized by the Board of
Directors of the corporation, or (iii) such indemnification is provided by the
corporation, in its sole discretion, pursuant to the powers vested in the
corporation under the Delaware General Corporation Law.

     SECTION 11.2 OTHER OFFICERS, EMPLOYEES AND OTHER AGENTS. The corporation
shall have power to indemnify its other officers, employees and other agents as
set forth in the Delaware General Corporation Law.

     SECTION 11.3 GOOD FAITH.

          (a) For purposes of any determination under this Article XI, a
Director or executive officer shall be deemed to have acted in good faith and in
a manner such officer


                                       18
<PAGE>

reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, to have had
no reasonable cause to believe that such officer's conduct was unlawful, if such
officer's action is based on information, opinions, reports and statements,
including financial statements and other financial data, in each case prepared
or presented by:

          (i)   one or more officers or employees of the corporation whom the
                Director or executive officer believed to be reliable and
                competent in the matters presented;

          (ii)  counsel, independent accountants or other persons as to matters
                which the Director or executive officer believed to be within
                such person's professional competence; and

          (iii) with respect to a Director, a committee of the Board upon which
                such Director does not serve, as to matters within such
                committee's designated authority, which committee the Director
                believes to merit confidence; so long as, in each case, the
                Director or executive officer acts without knowledge that would
                cause such reliance to be unwarranted.

          (b) The termination of any proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which such person reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal proceeding, that
such person had reasonable cause to believe that his conduct was unlawful.

          (c) The provisions of this Section 11.3 shall not be deemed to be
exclusive or to limit in any way the circumstances in which a person may be
deemed to have met the applicable standard of conduct set forth by the Delaware
General Corporation Law.

     SECTION 11.4 EXPENSES. The corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by any Director or executive officer in connection with such proceeding
upon receipt of an undertaking by or on behalf of such person to repay said
amounts if it should be determined ultimately that such person is not entitled
to be indemnified under this Article XI or otherwise.

     Notwithstanding the foregoing, unless otherwise determined pursuant to
Section 11.5 of this Article XI, no advance shall be made by the corporation if
a determination is reasonably and promptly made (i) by the Board of Directors by
a majority vote of a quorum consisting of Directors who were not parties to the
proceeding, or (ii) if such quorum is not obtainable, or, even if obtainable, a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, that the facts known to the decision-making party at the time
such determination is made demonstrate clearly and convincingly that such person
acted in bad faith or in a manner that such person did not believe to be in or
not opposed to the best interests of the corporation.


                                       19
<PAGE>

     SECTION 11.5 ENFORCEMENT. Without the necessity of entering into an express
contract, all rights to indemnification and advances to Directors and executive
officers under this Article XI shall be deemed to be contractual rights and be
effective to the same extent and as if provided for in a contract between the
corporation and the Director or executive officer. Any right to indemnification
or advances granted by this Article XI to a Director or executive officer shall
be enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part, or (ii) no disposition of such claim is made within
ninety (90) days of request therefor. The claimant in such enforcement action,
if successful in whole or in part, also shall be entitled to be paid the expense
of prosecuting his claim. The corporation shall be entitled to raise as a
defense to any such action that the claimant has not met the standards of
conduct that make it permissible under the Delaware General Corporation Law for
the corporation to indemnify the claimant for the amount claimed. Neither the
failure of the corporation (including its Board of Directors, independent legal
counsel or its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because such person has met the applicable standard of conduct
set forth in the Delaware General Corporation Law, nor an actual determination
by the corporation (including its Board of Directors, independent legal counsel
or its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that claimant
has not met the applicable standard of conduct.

     SECTION 11.6 NON-EXCLUSIVITY OF RIGHTS. The rights conferred on any person
by this Article XI shall not be exclusive of any other right which such person
may have or hereafter acquire under any statute, provision of the Certificate of
Incorporation, Bylaws, agreement, vote of stockholders or disinterested
Directors or otherwise, both as to action in his official capacity and as to

     SECTION 11.10 SAVINGS CLAUSE. If this Article XI or any portion hereof

     SECTION 11.11 CERTAIN DEFINITIONS. For the purposes of this Article XI, the
following definitions shall apply:

          (a) The term "proceeding" shall be broadly construed and shall

resulting corporation, any constituent corporation (including any constituent of

directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Article XI with respect to the resulting or surviving corporation as he
would have with respect to such constituent corporation if its separate
existence had continued.

of the participants and beneficiaries of an employee benefit plan shall be
deemed to have acted in a manner "not opposed to the best interests of the
corporation" as referred to in this Article XI.

                                  ARTICLE XII

                                     NOTICES

     SECTION 12.1 NOTICE TO STOCKHOLDERS. Unless the Certificate of
Incorporation requires otherwise, whenever, under any provisions of these
Bylaws, notice is required to be given to any stockholder, it shall be given in
writing, timely and duly deposited in the United States mail, postage prepaid,
and addressed to such stockholder's last known post office address as shown by
the stock record of the corporation or its transfer agent.

     SECTION 12.2 NOTICE TO DIRECTORS. Any notice required to be given to any
Director may be given by the method stated in Section 12.1, or by facsimile,
telex or telegram, except that such notice other than one which is delivered
personally shall be sent to such address as such Director shall have filed in
writing with the Secretary, or, in the absence of such filing, to the last known
post office address of such Director. It shall not be necessary that the same
method of giving notice be employed in respect of all Directors, but one
permissible method may be employed in respect of any one or more, and any other
permissible method or methods may be employed in respect of any other or others.

     SECTION 12.3 ADDRESS UNKNOWN. If no address of a stockholder or Director be
known, notice may be sent to the principal executive officer of the corporation.

     SECTION 12.4 AFFIDAVIT OF MAILING. An affidavit of mailing, executed by a
duly authorized and competent employee of the corporation or its transfer agent
appointed with respect to the class of stock affected, specifying the name and
address or the names and addresses of the stockholder or stockholders, or
Director or Directors, to whom any such notice or notices was or were given, and
the time and method of giving the same, shall be conclusive evidence of the
statements therein contained.

     SECTION 12.5 TIME NOTICES DEEMED GIVEN. All notices given by mail, as above
provided, shall be deemed to have been given as at the time of mailing, and all
notices given by facsimile, telex or telegram shall be deemed to have been given
as of the sending time recorded at the time of transmission.

     SECTION 12.6 FAILURE TO RECEIVE NOTICE. The period or limitation of time
within which any stockholder may exercise any option or right, or enjoy any
privilege or benefit, or be required to act, or within which any Director may
exercise any power or right, or enjoy any privilege, pursuant to any notice sent
such person in the manner above provided, shall not be affected or extended in
any manner by the failure of such stockholder or such Director to receive such
notice.

     SECTION 12.7 NOTICE TO PERSON WITH WHOM COMMUNICATION IS UNLAWFUL. Whenever
notice is required to be given, under any provision of law or of the Certificate
of Incorporation or Bylaws of the corporation, to any person with whom
communication is unlawful, the giving of such notice to such person shall not be
required and there shall be no duty to apply to any governmental authority or
agency for a license or permit to give such notice to such person. Any action or
meeting which shall be taken or held without notice to any such


                                       22
<PAGE>

person with whom communication is unlawful shall have the same force and effect
as if such notice had been duly given. In the event that the action taken by the
corporation is such as to require the filing of a certificate under any
provision of the Delaware General Corporation Law, the certificate shall state,
if such is the fact and if notice is required, that notice was given to all
persons entitled to receive notice except such persons with whom communication
is unlawful.

     SECTION 12.8 NOTICE TO PERSON WITH UNDELIVERABLE ADDRESS. Whenever notice
is required to be given, under any provision of law or the Certificate of
Incorporation or Bylaws of the corporation, to any stockholder to whom (i)
notice of two consecutive annual meetings, and all notices of meetings to such
person during the period between such two consecutive annual meetings, or (ii)
all, and at least two, payments (if sent by first class mail) of dividends or
interest on securities during a twelve-month period, have been mailed addressed
to such person at such person's address as shown on the records of the
corporation and have been returned undeliverable, the giving of such notice to
such person shall not be required. Any action or meeting which shall be taken or
held without notice to such person shall have the same force and effect as if
such notice had been duly given. If any such person shall deliver to the
corporation a written notice setting forth such person's then current address,
the requirement that notice be given to such person shall be reinstated. In the
event that the action taken by the corporation is such as to require the filing
of a certificate under any provision of the Delaware General Corporation Law,
the certificate need not state that notice was not given to persons to whom
notice was not required to be given pursuant to this paragraph.

                                  ARTICLE XIII

                                   AMENDMENTS

Incorporation, these Bylaws may be altered, amended or repealed, or new Bylaws
may be adopted, by the holders of two-thirds of the outstanding voting shares or
by the Board of Directors, when such power is conferred upon the Board of
Directors by the Certificate of Incorporation, at any regular meeting of the
stockholders or of the Board of Directors or at any special meeting of the
stockholders or of the Board of Directors if notice of such alteration,
amendment, repeal or adoption of new Bylaws be contained in the notice of such
special meeting. If the power to adopt, amend or repeal Bylaws is conferred upon
the Board of Directors by the Certificate of Incorporation, it shall not divest
or limit the power of the stockholders to adopt, amend or repeal Bylaws.

     SECTION 13.2 APPLICATION OF BYLAWS. In the event that any provisions of
these Bylaws is or may be in conflict with any law of the United States, of the
state of incorporation of the corporation or of any other governmental body or
power having jurisdiction over this corporation, or over the subject matter to
which such provision of these Bylaws applies, or may apply, such provision of
these Bylaws shall be inoperative to the extent only that the operation thereof
unavoidably conflicts with such law, and shall in all other respects be in full
force and effect.

otherwise assist any officer or other employee of the corporation or of its

without interest and may be unsecured, or secured in such manner as the Board of
Directors shall approve, including, without limitation, a pledge of shares of

or restrict the powers of guaranty or warranty of the corporation at common law
or under statute.

         2.1 RESTRICTIONS ON TRANSFER.

                  (a) Each Holder agrees not to make any disposition of all or
any portion of the Shares or Registrable Securities unless and until:

                           (i) There is then in effect a registration statement
under the Securities Act covering such proposed disposition and such disposition
is made in accordance with such registration statement; or

                           (ii) (A) The transferee has agreed in writing to be
bound by this Section 2.1, (B) such Holder shall have notified the Company of
the proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (C) if
such disposition is being effected other than pursuant to Rule 144 and if
reasonably requested by the Company, such Holder shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such shares under the
Securities Act.

Notwithstanding the provisions of paragraphs (i) and (ii) above, no such
registration statement or opinion of counsel shall be necessary for a transfer
which does not require registration under the Securities Act by a Holder which
is (A) a partnership to its partners or former partners in accordance



                                     - 3 -
<PAGE>

with their interests in such partnership, (B) a corporation to its shareholders
in accordance with their interests in the corporation, (C) a limited liability
company to its members or former members in accordance with their interests in
the limited liability company, or (D) to the Holder's family members or into a
trust for the benefit of such persons; provided in each case the transferee will
be subject to the terms of this Section 2.1 to the same extent as if he were an
original Holder hereunder.

                  (b) In addition to any legend required under applicable state
securities laws or as provided elsewhere in this Agreement, each certificate
representing Shares or Registrable Securities shall (unless otherwise permitted
by the provisions of this Agreement) be stamped or otherwise imprinted with a
legend substantially similar to the following:

         THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR
         OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND
         UNTIL REGISTERED UNDER THE ACT OR UNLESS THE COMPANY HAS RECEIVED AN
         OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT
         SUCH REGISTRATION IS NOT REQUIRED.

                  (c) The Company shall be obligated to reissue promptly
unlegended certificates at the request of any holder thereof if the holder shall
have obtained an opinion of counsel (which counsel may be counsel to the
Company) reasonably acceptable to the Company to the effect that the securities
proposed to be disposed of may lawfully be so disposed of without registration,
qualification or legend; provided however, any legend required to remain by any
other agreement shall not be removed.

                  (d) Any legend endorsed on an instrument pursuant to
applicable state securities laws and the stop-transfer instructions with respect
to such securities shall be removed upon receipt by the Company of an order from
the appropriate blue sky authority authorizing such removal.

         2.2 DEMAND REGISTRATION.

                  (a) Subject to the conditions of this Section 2.2, if the
Company receives a written request from the Holders of 40% of the Shares (or any
Common Stock issued upon conversion thereof) (the "Initiating Holders") that the
Company file a registration statement, on Form S-1, under the Securities Act
covering the registration of at least 25% of the Registrable Securities or such
number of shares of Registrable Securities anticipated to have an aggregate
offering price of not less than $10,000,000, then the Company shall, within
thirty (30) days of the receipt thereof, give written notice of such request to
all Holders, and subject to the limitations of this Section 2.2, use its best
efforts to effect, as soon as practicable, the registration under the Securities
Act of all Registrable Securities that the Holders request to be registered.

                  (b) If the Initiating Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
this Section 2.2 and the Company shall include such information in the written
notice referred to in Section 2.2(a). In such event, the right of any Holder to
include its Registrable Securities in such registration shall be conditioned
upon such Holder's participation in



                                     - 4 -
<PAGE>

such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by a majority in interest of
the Initiating Holders and such Holder) to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall
enter into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by a majority of the Initiating
Holders (which underwriter or underwriters shall be reasonably acceptable to the
Company). Notwithstanding any other provision of this Section 2.2, if the
underwriter advises the Company that marketing factors require a limitation of
the number of securities to be underwritten, then the Company shall advise all
Holders of Registrable Securities which would otherwise be underwritten pursuant
hereto that the number of shares that may be included in the underwriting shall
be allocated to the Holders of such Registrable Securities on a pro rata basis
based on the number of Registrable Securities requested by each such Holder, and
the Holders to be included in the registration (including the Initiating
Holders). Any Registrable Securities excluded or withdrawn from such
underwriting shall be withdrawn from the registration.

                  (c) The Company shall not be required to effect a registration
pursuant to this Section 2.2:

                           (i) after the Company has effected two (2)
registrations pursuant to this Section 2.2, and such registrations have been
declared or ordered effective or withdrawn by the Holders;

                           (ii) during the period starting with the date of
filing of, and ending on the date ninety (90) days following the effective date
of, any registration statement on Form S-1;

                           (iii) if within thirty (30) days of receipt of a
written request from Initiating Holders pursuant to Section 2.2(a), the Company
gives notice to the Holders of the Company's intention to make its Initial
Offering within ninety (90) days;

                           (iv) if (A) at the time the Company receives a
request for registration in accordance with this Section 2.2 the Company shall
then be engaged in any material transaction (such as, by way of example only,
negotiating a merger, acquisition, joint-venture or introduction of a major new
product) the disclosure of which in a Registration Statement, in the reasonable
judgment of a majority of the Board of Directors, exercised in good faith, would
be adverse to the Company's best interests, or (B) if the Company shall furnish
to Holders requesting a registration pursuant to this Section 2.2 a certificate
signed by a majority of the Board of Directors stating that in the Board of
Directors' reasonable judgment, exercised in good faith, the Company's earnings
or the occurrence of some other material event are not at such time appropriate
for disclosure, or, that it would be seriously detrimental to the Company and
its stockholders for such registration statement to be effected at such time,
then, in either of such events, the Company shall have the right to defer such
filing for a period of not more than ninety (90) days after receipt of the
request of the Initiating Holders; provided that such rights to delay a request
shall be exercised by the Company in the aggregate not more than once in any
twelve (12) month period; or

                           (v) prior to the earlier to occur of (a) September 1,
2000 or (b) six months after the Closing of the Initial Offering.

         2.3 PIGGYBACK REGISTRATION.

                  (a) The Company shall notify all Holders in writing at least
ninety (90) days prior to the filing of any registration statement under the
Securities Act for purposes of a public offering of securities of the Company
(including, but not limited to, registration statements relating to secondary
offerings of securities of the Company, but excluding registration statements
relating to employee benefit plans or with respect to corporate reorganizations
or other transactions under Rule 145 of the Securities Act) and will afford an
opportunity to include in such registration statement all or part of such
Registrable Securities held by such Holder. Each Holder desiring to include in
any such registration statement all or any part of the Registrable Securities
held by it shall, within fifteen (15) days after the above-described notice from
the Company, so notify the Company in writing. Such notice shall state the
intended method of disposition of the Registrable Securities by such Holder. If
a Holder decides not to include all of its Registrable Securities in any
registration statement thereafter filed by the Company, such Holder shall
nevertheless continue to have the right to include any Registrable Securities in
any subsequent registration statement or registration statements as may be filed
by the Company with respect to offerings of its securities, all upon the terms
and conditions set forth herein.

                  (b) If the registration statement under which the Company
gives notice under this Section 2.3 is for an underwritten offering, the Company
shall so advise the Holders of Registrable Securities. In such event, the right
of any such Holder to be included in a registration pursuant to this Section 2.3
shall be conditioned upon such Holder's participation in such underwriting and
the inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein. All Holders proposing to distribute their Registrable
Securities (and, if applicable, any and all other selling shareholders who may
be permitted to register shares) through such underwriting shall enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company. Notwithstanding any other
provision of the Agreement to the contrary, if the underwriter determines in
good faith that marketing factors require a limitation of the number of shares
to be underwritten, the number of shares that may be included in the
underwriting shall be allocated, first, to the Company; second, to the Holders
on a PRO RATA basis based on the total number of Registrable Securities
requested by each Holder to be registered; third, to any stockholder of the
Company (other than a Holder) on a PRO RATA basis. No such reduction shall
reduce the securities being offered by the Company for its own account to be
included in the registration and underwriting; PROVIDED, however, that in no
event shall the amount of securities of the selling Holders included in the
registration be reduced below thirty percent (30%) of the total amount of
securities included in such registration, unless such offering is the Initial
Offering and such registration does not include shares of any other selling
stockholders, in which event any or all of the Registrable Securities of the
Holders may be excluded in accordance with the immediately preceding sentence.
In no event shall shares of any other selling stockholder be included in such
registration which would reduce the number of shares which may be included by
Holders without the written consent of Holders of not less than two-thirds of
the Registrable Securities proposed to be sold in the offering.

                  (c) Right to Terminate Registration. The Company shall have
the right to terminate or withdraw any registration initiated by it under this
Section 2.3 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration.



                                     - 6 -
<PAGE>

The Registration Expenses of such withdrawn registration shall be borne by the
Company in accordance with Section 2.6 hereof.

         2.4 FORM S-3 REGISTRATION.

         In case the Company shall receive from any Holder or Holders of (A) a
majority of the Registrable Securities relating to the Company's Series A
Convertible Preferred Stock (the "Series A Registrable Securities"), (B) a
majority of the Registrable Securities relating to the Company's Series C
Convertible Preferred Stock (the Series C Registrable Securities") or (C) any
Registrable Securities relating to the Company's Series D Convertible Preferred
Stock (in any case, the "Initiating S-3 Holders") a written request or requests
that the Company effect a registration on Form S-3 (or any successor to Form
S-3) or any similar short-form registration statement and any related
qualification or compliance with respect to all or a part of the Registrable
Securities owned by such Holder or Holders, the Company will:

                  (a) promptly give written notice of the proposed registration,
and any related qualification or compliance, to all other Holders of Registrable
Securities; and

                  (b) as soon as practicable, effect such registration and all
such qualifications and compliances as may be so requested and as would permit
or facilitate the sale and distribution of all or such portion of such Holder's
or Holders' Registrable Securities as are specified in such request, together
with all or such portion of the Registrable Securities of any other Holder or
Holders joining in such request as are specified in a written request given
within fifteen (15) days after receipt of such written notice from the Company;
provided, however, that the Company shall not be obligated to effect any such
registration, qualification or compliance pursuant to this Section 2.4:

                           (i) if Form S-3 (or any successor or similar form) is
not available for such offering by the Holder;

                           (ii) if the Holders, together with the holders of any
other securities of the Company entitled to inclusion in such registration,
propose to sell Registrable Securities and such other securities (if any) at an
aggregate price to the public of less than $500,000;

                           (iii) if (A) at the time the Company receives a
request for registration in accordance with this Section 2.4 the Company shall
then be engaged in any material transaction (such as, by way of example only,
negotiating a merger, acquisition, joint-venture or introduction of a major new
product) the disclosure of which in a Registration Statement, in the reasonable
judgment of a majority of the Board of Directors, exercised in good faith, would
be adverse to the Company's best interests, or (B) if the Company shall furnish
to the Holders requesting a registration pursuant to this Section 2.4 a
certificate signed by a majority of the Board of Directors of the Company
stating that in the Board of Directors' reasonable judgment, exercised in good
faith, the Company's earnings or the occurrence of some other material event are
not at such time appropriate for disclosure, or that it would be seriously
detrimental to the Company and its stockholders for such Form S-3 Registration
to be effected at such time, then, in either of such events, the Company shall
have the right to defer the filing of the Form S-3 registration statement for a
period of not more than ninety (90) days after receipt of the request of the
Holder or Holders under this Section 2.4;



                                     - 7 -
<PAGE>

provided, that such rights to delay a request shall be exercised by the Company
in the aggregate not more than once in any twelve (12) month period.

                           (iv) in any particular jurisdiction in which the
Company would be required to qualify to do business or to execute a general
consent to service of process in effecting such registration, qualification or
compliance.

                  (c) Subject to the foregoing, the Company will file a Form S-3
registration statement covering the Registrable Securities and other securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Holders.

         2.5 IPO ALLOCATION.

         In the event of a bona fide, underwritten initial public offering of
the capital stock of the Company (the "IPO"), the Company shall use commercially
reasonable efforts to require that the managing underwriters of the IPO
establish a directed share program (the "PROGRAM") in connection with the IPO.
The Program shall consist of that number of shares of capital stock (the
"PROGRAM SHARES") determined by dividing $3,000,000 by the initial price to the
public set forth on the cover page of the final prospectus distributed in
connection with the IPO (the "IPO PRICE"), provided that, if necessary to
complete the IPO, the number of Program Shares may be reduced to the maximum
number permitted under the rules and requirements of the NASD. The Company shall
cause the managing underwriters (subject to the consent of the underwriters) to
give priority to the holders of the Company's Series C Convertible Preferred
Stock (or Common Stock issuable upon conversion thereof)(the "SERIES C
HOLDERS"), PRO RATA in accordance with their relative holdings of Series C
Convertible Preferred Stock (or Common Stock issued upon conversion thereof)
with respect to the Program Shares in allocating the shares available for
purchase in the Program. The Series C Holders, PRO RATA as aforesaid, shall have
the option, but not the obligation, to purchase all or any portion of the
Program Shares at the IPO Price. Notwithstanding the foregoing, in no event
shall the Investors designated on the signature pages hereto as the "TCV
Investors" have the rights under this Section 2.5 with respect to less than such
number of Program Shares that, when multiplied by the IPO Price, equals
$1,500,000 (such product being referred to as the "Program Value"), and if the
Program Value shall be less than $1,500,000, then the TCV Investors shall have
the rights under this Section 2.5 with respect to all of the Program Shares (the
number of Program Shares as to which the TCV Investors are to have the rights
under this Section 2.5 in accordance with this sentence are referred to as the
"TCV Minimum Shares"). If, in order to give effect to the operation of the
preceding sentence, the Investors other than the TCV Investors obtain rights
under this Section 2.5 with respect to less than their respective PRO RATA share
of the Program Shares, then (i) such other Investors shall have the rights under
this Section 2.5 with respect to all of the Program Shares other than the TCV
Minimum Shares, if there shall be any Program Shares in addition to the TCV
Minimum Shares, and (ii) such other Investors shall share such rights PRO RATA
in accordance with their relative holdings of Series C Convertible Preferred
Stock (or Common Stock issued upon the conversion thereof.

         2.6 EXPENSES OF REGISTRATION.

         Except as specifically provided herein, all Registration Expenses
incurred in connection with any registration, qualification or compliance
pursuant to Section 2.2 or any registration under



                                     - 8 -
<PAGE>

Section 2.3 or Section 2.4 herein shall be borne by the Company. All Selling
Expenses incurred in connection with any registrations hereunder shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of shares so registered. The Company shall not, however, be required to
pay for expenses of any registration proceeding begun pursuant to Section 2.2 or
2.4, the request of which has been subsequently withdrawn by the Initiating
Holders or the Initiating S-3 Holders, as the case may be, unless (a) the
withdrawal is based upon material adverse information concerning the Company of
which the Initiating Holders or the Initiating S-3 Holders, as the case may be
were not aware at the time of such request or (b) the Holders of a majority of
Registrable Securities agree to forfeit their right to one requested
registration pursuant to Section 2.2 or Section 2.4, as applicable, in which
event such right shall be forfeited by all Holders. If the Holders are required
to pay the Registration Expenses, such expenses shall be borne by the holders of
securities (including Registrable Securities) requesting such registration in
proportion to the number of shares for which registration was requested. If the
Company is required to pay the Registration Expenses of a withdrawn offering
pursuant to clause (a) above, then the Holders shall not forfeit their rights
pursuant to Section 2.2 or Section 2.4 to a demand registration.

         2.7 OBLIGATIONS OF THE COMPANY.

         Whenever required to effect the registration of any Registrable
Securities, the Company shall, as expeditiously as reasonably possible:

                  (a) Prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use all reasonable efforts to
cause such registration statement to become effective, and, upon the request of
the Initiating Holders or the Initiating S-3 Holders, as the case may be, keep
such registration statement effective for up to one hundred and eighty (180)
days or, if earlier, until the Holder or Holders have completed the distribution
related thereto.

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

                  (c) Furnish to the Holders such number of copies of the
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of the Registrable
Securities owned by them.

                  (d) Use all reasonable efforts to register and qualify the
securities covered by such registration under such other securities laws and
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or to file a general consent
to service of process in any such states or jurisdictions.

                  (e) In the event of any underwritten public offering, enter
into and perform its obligations under a underwriting agreement, in usual and
customary form, with the managing underwriter(s) of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.


                                     - 9 -
<PAGE>

                  (f) Notify each Holder of Registrable Securities covered by
such registration statement that a prospectus relating thereto is required to be
delivered under the Securities Act of any event that would cause the prospectus
included in such registration statement, as then in effect, to include an untrue
statement of a material fact or to omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing.

                  (g) Furnish, at the request of the Initiating Holders holding
a majority of the shares participating in the offering or the Initiating S-3
Holders holding a majority of the shares participating in the offering, as the
case may be, on the date that such Registrable Securities are delivered to the
underwriters for sale, if such securities are being sold through underwriters,
or, if such securities are not being sold through underwriters, on the date that
the registration statement with respect to such securities becomes effective,
(i) an opinion, dated as of such date, from the counsel representing the Company
for the purposes of such registration, in the form and substance as is
customarily given to underwriters in an underwritten public offering and
reasonably satisfactory to a majority of the Holders requesting registration,
addressed to the underwriters, if any, and to the Holders requesting the
registration of their Registrable Securities and (ii) a letter dated as of such
date, from the independent certified public accountants of the Company, in form
and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering and reasonably
satisfactory to a majority of the Holders requesting registration, addressed to
the underwriters, if any, and if permitted by applicable accounting standards,
to the Holders requesting the registration of their Registrable Securities.

         2.8 TERMINATION OF REGISTRATION RIGHTS.

         All registration rights granted to a Holder under this Article II
(other than under Section 2.3 with respect to underwritten offerings) shall
terminate and be of no further force and effect upon the earlier of (i) the
fifth anniversary of the consummation of the Initial Offering and (ii) such date
as all Registrable Securities held by and issuable to such Holder may be sold in
the manner described in Rule 144 during any ninety (90) day period.

         2.9 DELAY OF REGISTRATION; FURNISHING INFORMATION.

                  (a) No Holder shall have any right to obtain or seek an
injunction restraining or otherwise delaying any such registration as the result
of any controversy that might arise with respect to the interpretation or
implementation of this Section 2.

                  (b) It shall be a condition precedent to the obligations of
the Company to take any action pursuant to Sections 2.2, 2.3 or 2.4 that the
selling Holders shall furnish to the Company such information regarding
themselves, the Registrable Securities held by them and the intended method of
disposition of such securities as shall be required to effect the registration
of their Registrable Securities.

         2.10 INDEMNIFICATION.


                                     - 10 -
<PAGE>

         In the event any Registrable Securities are included in a registration
statement under Sections 2.2, 2.3 or 2.4:

                  (a) To the extent permitted by law, the Company shall
indemnify and hold harmless each Holder, the partners, officers, directors and
legal counsel of each Holder, any underwriter (as defined in the Securities Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Exchange Act, against any
losses, claims, damages or liabilities (joint or several) to which the may
become subject under the Securities Act, the Exchange Act or other federal or
state law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation") by the Company: (i) any
untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospects or final
prospectus contained therein and any amendments or supplements thereto, (ii) the
omission or alleged omission to state a material fact required to be stated
therein, or necessary to make the statements therein not misleading, or (iii)
any violation or alleged violation by the Company of the Securities Act, the
Exchange Act, any state securities laws or any rule or regulation promulgated
under the Securities Act, the Exchange Act or any state securities laws in
connection with the offering covered by such registration statement; and the
Company shall reimburse each such Holder, partner, officer or director,
underwriter or controlling person on a current basis for any legal or other
expense reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided however,
that the indemnity agreement contained in this Section 2.10(a) shall not apply
to default judgments or amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Company, which consent shall not be unreasonably withheld, nor shall the
Company be liable in any such case for any such loss, claim, damage, liability
or action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by such Holder, partner,
officer, director, underwriter or controlling person of such Holder.

                  (b) To the extent permitted by law, each Holder shall, if
Registrable Securities held by such Holder are included in the securities as to
which such registration qualifications or compliance is being effected,
indemnify and hold harmless the Company, each of its directors, its officers,
and legal counsel and each person, if any, who controls the Company within the
meaning of the Securities Act, any underwriter and any other Holder selling
securities under such registration statement or any of such other Holder's
partners, directors or officer or any person who controls such Holder, against
any losses, claims, damages or liabilities (joint or several) to which the
Company or any such director, officer, controlling person, underwriter or other
such Holder, or partner, director, officer or controlling person of such other
Holder may become subject under the Securities Act, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent (and only to the extent) that such Violation occurs due
to the Company's reliance upon written information furnished by such Holder
under an instrument duly executed by such Holder and stated to be specifically
for use in connection with such registration; and each such Holder shall
reimburse any legal or other expenses reasonably incurred by the Company or any
such director, officer, controlling person, underwriter or other Holder, or
partner, officer, director or controlling person of such other Holder in
connection with investigating or defending any such loss, claim, damage,


                                     - 11 -
<PAGE>

liability or action if it is judicially determined that there was such a
Violation; provided, however, that the indemnity agreement contained in this
Section 2.10(b) shall not apply to default judgments or amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Holder, which consent shall
not be unreasonably withheld; provided further, that in no event shall any
indemnity under this Section 2.10 exceed the net proceeds from the offering
received by such Holder.

                  (c) Promptly after receipt by an indemnified party under this
Section 2.10 of notice of the commencement of any action (including any
governmental action), such indemnified party shall, if a claim in respect
thereof is to be made against any indemnifying party under this Section 2.10,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any indemnifying party
similarly notified, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if materially prejudicial to its ability to
defend such action, shall relieve such indemnifying party of any liability to
the indemnified party under this Section 2.10, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section
2.10.

                  (d) If the indemnification provided for in this Section 2.10
is held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any losses, claims, damages or liabilities referred to
herein, the Indemnifying party, in lieu of indemnifying such indemnified party
thereunder, shall to the extent permitted by applicable law contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and of the indemnified
party on the other in connection with the Violation(s) that resulted in such
loss, claim, damage or liability, as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by a court of law by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission; provided, that in no event shall any contribution by a
Holder hereunder exceed the net proceeds from the offering received by such
Holder.

                  (e) The obligations of the Company and Holders under this
Section 2.10 shall survive completion of any offering of Registrable Securities
in a registration statement and the termination of this Agreement. No
indemnifying party, in the defense of any such claim or litigation, shall,
except with the consent of each indemnified party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party a
release from all liability in respect to such claim or litigation.

         2.11 ASSIGNMENT OF REGISTRATION RIGHTS.

         The rights to cause the Company to register Registrable Securities
pursuant to this Article II may be assigned by a Holder to a transferee or
assignee of Shares or Registrable Securities, provided such transferee or
assignee (i) is a subsidiary, parent, general partner, limited partner or
retired partner of a Holder, (ii) is a Holder's family member or trust for the
benefit of an individual Holder, or (iii) acquires at least one hundred thousand
(100,000) Shares or Registrable Securities (as adjusted for stock splits and
combinations) and is not a competitor of the Company (as reasonably determined
by the Board of Directors); provided, however, (A) the transferor shall, within
ten (10) days after such transfer, furnish to the Company written notice of the
name and address of such transferee or assignee and the securities with respect
to which such registration rights are being assigned and (B) such transferee
shall agree to be subject to all restrictions set forth in this Agreement and
the Restated Co-Sale Agreement.

         2.12 AMENDMENT OF REGISTRATION RIGHTS.

         Any provision of this Section 2 may be amended and the observance
thereof may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the holders of
a majority of the Series A Registrable Securities, voting or acting separately
as a class, a majority of the Series C Registrable Securities, voting or acting
separately as a class, and a majority of the Series D Registrable Securities,
voting or acting separately as a class, provided that all Holders are affected
by such amendment or waiver in a substantially similar fashion. If any amendment
treats any class of holders differently than any other class, the affected class
must approve or waive the amendment or modification by a majority vote of the
affected class. Any amendment or waiver effected in accordance with this Section
2.12 shall be binding upon each Holder and the Company. By acceptance of any
benefits under this Section 2, Holders hereby agree to be bound by the
provisions hereunder.

         2.13 LIMITATION ON SUBSEQUENT REGISTRATION RIGHTS.

         After the date of this Agreement, the Company shall not, without the
prior written consent of the holders of a majority of the Series A Registrable
Securities, voting or acting separately as a class, a majority of the Series C
Registrable Securities, voting or acting separately as a class, and a majority
of the Series D Registrable Securities voting or acting separately as a class,
enter into any agreement with any holder or prospective holder of any securities
of the Company that would grant such holder any registration rights with respect
to such securities.

         2.14 "MARKET STAND-OFF" AGREEMENT.

         If requested by the Company or the representative of the underwriters
of the Common Stock (or other securities), each Holder and a transferee of a
Holder, regardless of whether such transferee has registration rights hereunder,
shall not sell or otherwise transfer or dispose of any Registrable Securities
held by such Holder (other than those included in the registration) for a period
specified by the representative of the underwriters not to exceed one hundred
eighty (180) days following the effective date of a registration statement of
the Company filed under the Securities Act, provided that:


                                     - 13 -
<PAGE>

                  (a) such agreement shall apply only to the Initial Offering;

                  (b) all officers and directors of the Company and holders of
at least one percent (1%) of the Company's voting securities enter into similar
agreements; and

                  (c) such agreement shall provide that any discretionary waiver
or termination of the restrictions of such agreements by the Company or the
representatives of the underwriters shall apply to all persons subject to such
agreements pro rata based on the number of Registrable Securities held.

         The obligations described in this Section 2.14 shall not apply to a
registration relating solely to employee benefit plans on Form S-1 or Form S-8
or similar forms that may be promulgated in the future, or a registration
relating solely to a Commission Rule 145 transaction on Form S-4 or similar
forms that may be promulgated in the future. The Company may impose
stop-transfer instructions with respect to the shares of Common Stock (or other
securities) subject to the foregoing restriction until the end of said one
hundred eighty (180) day period.

         2.15 RULE 144 REPORTING.

         With a view to making available to the Holders the benefits of certain
rules and regulations of the SEC which may permit the sale of the Registrable
Securities to the public without registration, the Company agrees to use its
best efforts to:

                  (a) Make and keep public information available, as those terms
are understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the Securities Act, at all times that the Company is subject
to the reporting requirements of the Exchange Act, as amended;

                  (b) File with the SEC, in a timely manner, all reports and
other documents required of the Company under the Exchange Act; and

                  (c) So long as a Holder owns any Shares or Registrable
Securities, furnish to such Holder forthwith upon request a written statement by
the Company as to its compliance with the reporting requirements of said Rule
144 of the Securities Act, and of the Exchange Act (at any time after it has
become subject to such reporting requirements), a copy of the most recent annual
or quarterly report of the Company, and such other reports and documents as a
Holder may reasonably request in availing itself of any rule or regulation of
the SEC allowing it to sell any such securities without registration.

SECTION 3 COVENANTS OF THE COMPANY.

         3.1 BASIC FINANCIAL INFORMATION AND REPORTING.

                  (a) The Company will maintain true books and records of
account in which full and correct entries will be made of all its business
transactions pursuant to a system of accounting established and administered in
accordance with generally accepted accounting principles consistently applied,
and will set aside on its books all such proper accruals and reserves as shall
be



                                     - 14 -
<PAGE>

required under generally accepted accounting principles consistently applied. In
addition to the information described in Section 3.1(b), (c) and (d), the
Company shall provide in a timely manner any other information concerning the
Company and its business and affairs as any of the Investors may from time to
time reasonably request.

                  (b) As soon as practicable after the end of each fiscal year
of the Company and so long as any of the Shares are outstanding, and in any
event within one hundred twenty (120) days thereafter, the Company will furnish
to each Investor a consolidated balance sheet of the Company, as at the end of
such fiscal year, and an audited consolidated income statement and an audited
consolidated cash flow statement of the Company, for such year, all prepared in
accordance with generally accepted accounting principles consistently applied
and setting forth in each case in comparative form the figures from the previous
fiscal year, with an explanation of any material differences between them, all
in reasonable detail. Such financial statements shall be accompanied by a report
and opinion thereon by independent public accountants of national standing
selected by the Company's Board of Directors and a report by management with a
discussion of the Company's business, including any changes in the Company's
financial condition and any significant business developments.

                  (c) As long as any of the Shares are outstanding, the Company
will furnish each Investor, as soon as practicable after the end of the first,
second and third quarterly accounting periods in each fiscal year of the
Company, and in any event within forty-five (45) days thereafter, a consolidated
balance sheet of the Company as of the end of each such quarterly period, and a
consolidated income statement and a consolidated cash flow statement of the
Company for such period and for the current fiscal year to date, prepared in
accordance with generally accepted accounting principles, with the exception
that no notes need be attached to such statements and year-end audit adjustments
may not have been made, and setting forth in each case in comparative form the
figures from the previous fiscal year, with an explanation of any material
differences between them. Such financial statements shall be accompanied by a
report by management with a discussion of the Company's business, including any
changes in the Company's financial condition and any significant business
developments.

                  (d) As long as any of the Shares are outstanding, the Company
will furnish each Investor (i) at least thirty (30) days prior to the beginning
of each fiscal year an annual budget and operating plans for such fiscal year
(and, as soon as available, any subsequent revisions thereto); and (ii) as soon
as practicable after the end of each month, and in any event within thirty (30)
days thereafter, a consolidated balance sheet of the Company as of the end of
each such month, and a consolidated income statement and a consolidated cash
flow statement of the Company for such month and for the current fiscal year to
date, including a comparison to plan figures for such period, prepared in
accordance with generally accepted accounting principles consistently applied,
with the exception that no notes need be attached to such statements and
year-end audit adjustments may not have been made.

         3.2 INSPECTION RIGHTS.

         Each Investor or its authorized representatives shall have the right to
visit and inspect any of the properties of the Company or any of its
subsidiaries, including its corporate and financial records, and to discuss the
affairs, finances and accounts of the Company or any of its subsidiaries



                                     - 15 -
<PAGE>

with its officers, and to review such information as it may reasonably request
all at such reasonable times and as often as may be reasonably requested;
provided, however, that the Company shall not be obligated under this Section
3.2 with respect to a competitor of the Company or with respect to information
which the Board of Directors determines in good faith is confidential and should
not, therefore, be disclosed.

         3.3 CONFIDENTIALITY OF RECORDS.

         Each Investor agrees to use, and to use its diligent efforts to ensure
that its authorized representatives use, the same degree of care as such
Investor uses to protect its own confidential information to keep confidential
any information furnished to it which the Company identifies as being
confidential or proprietary (so long as such information is not in the public
domain), except that such Investor may disclose such proprietary or confidential
information to any partner, subsidiary or parent of such Investor for the
purpose of evaluating its investment in the Company as long as such partner,
subsidiary or parent agrees to be bound by the confidentiality provisions of
this Section 3.3. Notwithstanding the foregoing, each Investor shall be free to
distribute to its partners or shareholders summary information describing the
Company's performance.

         3.4 RESERVATION OF COMMON STOCK.

         The Company will at all times reserve and keep available, solely for
issuance and delivery upon the conversion of Shares, all Common Stock issuable
from time to time upon conversion of all the Shares.

         3.5 STOCK VESTING.

         Unless otherwise approved by the Board of Directors, all stock options
and other stock equivalents issued after the date of this Agreement to
employees, directors, consultants and other service providers shall be subject
to vesting over a minimum of four year period and with respect to any shares of
stock purchased by any such person, the Company's repurchase option shall
provide that upon such person's termination of employment or service with the
Company, with or without cause, the Company or its assignee (to the extent
permissible under applicable securities laws and other laws) shall have the
option to purchase at cost any unvested shares of stock held by such person.

         3.6 TERMINATION OF COVENANTS.

         The provisions of 3.1, 3.2, 3.3 and 3.4 of this Agreement shall expire,
terminate and be of no further force of effect on the date the Initial Offering
is consummated.

SECTION 4. RIGHTS OF FIRST REFUSAL.

         4.1 SUBSEQUENT OFFERINGS.

         The Investors shall have a right of first refusal to purchase their PRO
RATA portion of the Equity Securities, as defined below, that the Company may,
from time to time, propose to sell and issue



                                     - 16 -
<PAGE>

after the date of this Agreement, other than the Equity Securities excluded by
Section 4.6 hereof. The term "Equity Securities" shall mean (i) any Common
Stock, Preferred Stock or other security of the Company (other than debt
securities which are not convertible into and do not carry rights to acquire any
capital stock of the Company), (ii) any security convertible, with or without
consideration, into any Common Stock, Preferred Stock or other security
(including any option to purchase such a convertible security), (iii) any
security carrying any warrant or right to subscribe to or purchase any Common
Stock, Preferred Stock or other security or (iv) any such warrant or right.

         4.2 EXERCISE OF RIGHTS.

         If the Company proposes to issue any Equity Securities, it shall give
the Investors written notice of its intention, describing the Equity Securities,
the price and the terms and conditions upon which the Company proposes to issue
the same. The Investors shall have fifteen (15) days from the giving of such
notice to agree to purchase the Equity Securities for the price and upon the
terms and conditions specified in the notice by giving written notice to the
Company and stating therein the quantity of Equity Securities to be purchased.
Notwithstanding the foregoing, the Company shall not be required to offer or
sell such Equity Securities to any such Investor if it would cause the Company
to be in violation of applicable federal securities laws by virtue of such offer
or sale.

         4.3 ISSUANCE OF EQUITY SECURITIES TO OTHER PERSONS.

         If any Investor fails to exercise in full the rights of first refusal,
the Company shall have ninety (90) days thereafter to sell the Equity Securities
in respect of which the Investor's rights were not exercised, at a price and
upon general terms and conditions materially no more favorable to the purchasers
thereof than specified in the Company's notice to the Investor pursuant to
Section 4.2 hereof. If the Company has not sold such Equity Securities within 90
days of the notice provided pursuant to Section 4.2, the Company shall not
thereafter issue or sell such Equity Securities, without first offering such
securities to the Investor in the manner provided above.

         4.4 TERMINATION OF RIGHTS OF FIRST REFUSAL.

         The rights of first refusal established by this Section 4 shall
terminate upon either (a) the date of the Initial Offering or (b) with respect
to Investors holding Series A Convertible Preferred Stock or Series B
Convertible Preferred Stock, if fewer than 30% of the number of such Shares that
are outstanding (or in the case of Series B Convertible Preferred Stock, that
are issuable upon the exercise of an option therefor that is outstanding) as of
the date of this Agreement remain outstanding or (c) with respect to Investors
holding Series C Convertible Preferred Stock or Series C-1 Convertible Preferred
Stock, if fewer than 20% of the number of such shares that are outstanding (or,
in the case of Series C-1 Convertible Preferred Stock, that are issuable upon
the exercise of options therefor that are outstanding) as of the date of this
Agreement remain outstanding or (d) with respect to Investors holding Series D
Convertible Preferred Stock or Series D-1 Convertible Preferred Stock, if fewer
than 30% of the number of such shares that are outstanding (or, in the case of
Series D-1 Convertible Preferred Stock that are issuable upon the exercise of
Warrants therefor that are outstanding) as of the date of this Agreement remain
outstanding.

         4.5 TRANSFER OF RIGHTS OF FIRST REFUSAL.


                                     - 17 -
<PAGE>

         The rights of first refusal of the Investors under this Section 4 may
be transferred to the same parties, subject to the same restrictions as any
transfer of registration rights pursuant to Section 2.11.

         4.6 EXCLUDED SECURITIES.

         The rights of first refusal established by this Section 4 shall have no
application to any of the following Equity Securities:

                  (a) up to an aggregate amount of 2,000,000 shares of Common
Stock (and/or options, warrants or other Common Stock purchase rights issued
pursuant to such options, warrants or other rights) issued or to be issued to
employees, officers or directors of, or consultants or advisors to the Company
or any subsidiary, pursuant to stock purchase or stock option plans or other
similar arrangements that are approved by the Board of Directors;

                  (b) Stock issued pursuant to any rights or agreements
outstanding as of the date of this Agreement, options and warrants outstanding
as of the date of this Agreement, and stock issued pursuant to any such rights
or agreements granted after the date of this Agreement, provided that the rights
of first refusal established by this Article IV applied with respect to the
initial sale or grant by the Company of such rights or agreements;

                  (c) any Equity Securities issued for consideration other than
cash pursuant to a merger, consolidation, acquisition or similar business
combination;

                  (d) shares of Common Stock issued in connection with any stock
split, stock dividend or recapitalization by the Company;

                  (e) shares of Common Stock issued upon conversion of the
Shares;

                  (f) any Equity Securities issued pursuant to a public
offering; or

                  (g) any Equity Securities issued by the Company to an
operating company with compatible or complimentary products to effect a
strategic alliance with that company which is anticipated to provide to the
Company a well-defined economic benefit, provided that in no event shall the
number of shares of such Equity Securities so issued exceed in the aggregate
fifteen percent (15%) of the number of shares of Equity Securities outstanding
at the time of such issuance.

SECTION 5. MISCELLANEOUS.

         5.1 GOVERNING LAW.

Registrable Securities in its records as the absolute owner and holder thereof

                               AMENDMENT NO. 1 TO

             SECOND AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT

                THIS AMENDMENT NO. 1 (the "Amendment") dated as of February 26,
1999 to the Second Amended and Restated Investors' Rights Agreement dated as of
November 24, 1998 (the "Agreement"), by and among Vastera, Inc., a Delaware
corporation (the "Company"), and the holders of shares of the Company's Series A
Convertible Preferred Stock, par value $0.01 per share (the "Series A Preferred
Stock"), Series C Convertible Preferred Stock, par value $0.01 per share (the
"Series C Preferred Stock"), and Series D Convertible Preferred Stock, par value
$0.01 per share (the "Series D Preferred Stock"), listed on the signature pages
thereto (such holders, the "Series A Investors," the "Series C Investors" and
the "Series D Investors," respectively, and such holders are referred to in the
Agreement as the "Investors"), is hereby entered into by the Company, the
Investors and FDX Corporation, a Delaware corporation (the "New Investor"). The
undersigned Investors constitute the holders of at least a majority of the
Registrable Securities of each such class, as such term is defined in the
Agreement.

                WHEREAS, contemporaneously with the execution of this Amendment,
the Company is issuing and selling an aggregate 512,715 shares (the "New
Shares") of its Series D Preferred Stock and has agreed to issue a warrant (the
"Warrant") to purchase an aggregate of 385,505 shares of its Series D-1
Convertible Preferred Stock, par value $0.01 per share (the "Series D-1
Preferred Stock"), to the New Investor under the terms and conditions set forth
in that certain Amendment No. 1 dated as of the date hereof to the Series D
Convertible Preferred Stock and Warrant Purchase Agreement dated as of November
24, 1998; and

                WHEREAS, the Company and the Investors desire that the New
Investor be granted registration and other rights with respect to the New Shares
and the shares of Series D-1 Preferred Stock having the same terms and
conditions as the registration and other rights granted to the existing Series D
Investors with respect to the shares of Series D Preferred Stock.

                NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

                1. The New Shares purchased by the New Investor and the shares
of Common Stock of the Company, $0.01 par value per share (the "Common Stock"),
into which the New Shares may be converted are and shall be "Series D
Convertible Preferred Stock" and "Registrable Securities," respectively, as such
terms are used and defined in the Agreement. The New Shares are "Shares" as such
term is used and defined in the Agreement.


Amendment No. 1 to Second Amended
and Restated Investors' Rights Agreement

<PAGE>

                2. The Warrant issued to the New Investor shall be an "Option"
as such term is used and defined in the Agreement and may be exercised to
purchase Series D-1 Preferred Stock and such shares are and shall be "Series D-1
Convertible Preferred Stock" and "Shares" as such terms are used and defined in
the Agreement. The shares of Common Stock into which the Series D-1 Preferred
Stock may be converted are and shall be "Registrable Securities" as such term is
used and defined in the Agreement.

                3. The New Investor shall be a "Holder" and an "Investor" as
such terms are used and defined in the Agreement.

                4. The term "Related Agreements," as such term is presently
defined in the Agreement, shall, effective with the execution of this Amendment,
be redefined as follows:

                         "RELATED AGREEMENTS" mean the Preferred Stock Purchase
         Agreement and the related Option Agreement, both dated as of July 31,
         1996, the Series C and Series D Preferred Stock Purchase Agreement
         dated as of August 7, 1997, as amended, the Series D Convertible
         Preferred Stock and Warrant Purchase Agreement dated as of November 24,
         1998, as amended, and the Second Amended and Restated Right of First
         Refusal and Co-Sale Agreement dated as of November 24, 1998, as amended
         (the "Restated Co-Sale Agreement").

                5. Wherever the Agreement is itself referred to in the
Agreement, or wherever there are references in the Agreement to "hereunder,"
"hereof," "herein," or words of like import, they shall mean the Agreement, as
amended hereby.

                6. The New Investor hereby agrees to be bound by all the terms
and conditions of, and is hereby granted all of the rights of an "Investor" and
"Holder" under, the Agreement as though such New Investor had been an original
party to the Agreement, and by executing this Amendment, the New Investor
becomes a party thereto and is bound thereby. The Investors and the Company
acknowledge that they remain bound by all the terms and conditions of the
Agreement, as amended hereby.

                7. All notices, pursuant to Section 5.7 of the Agreement,
addressed to the New Investor shall be addressed as follows:

thereafter from enforcing each and every other provision of this Amendment. The
rights granted to the parties herein are cumulative and shall not constitute a
waiver of any party's right to assert all other legal remedies available to it
under the circumstances.

                10. This Amendment may be executed in two or more counterparts,
each of which shall be deemed an original, but all of which when taken together

agree upon request to execute any further documents or instruments necessary or
desirable to carry out the purposes or intent of this Amendment or the

the other parties identified on the signature pages hereof (the "Original

counterparts, each of which shall be deemed an original, but all of which when

         If any taxes are separately assessed against Landlord or the Project

at the specific request of Tenant, Tenant shall be solely responsible for the
payment of such tax.

         The net amount of any refund or credit in Real Estate Taxes obtained by

Landlord in connection with obtaining such refund or credit and not previously
recovered by Landlord as an Operating Expense) shall be passed through one
hundred percent (100%) to Tenant and ail other tenants, pro-rata in accordance
with their respective proportionate shares of property taxes.

         5.4      ESTIMATED PAYMENTS.

         During each calendar year or partial calendar year in the term, in
addition to monthly Rent, Tenant will pay to Landlord on the first day of each
month an amount equal to 1/12 of the product of Tenant's Share multiplied by the
"ESTIMATED TAXES AND EXPENSES" (defined below) for such calendar year.

         "ESTIMATED TAXES AND EXPENSES" for any calendar year means Landlord's
reasonable estimate of Operating Expenses and Real Estate Taxes for such
calendar year, less the product of the Expense Base and the Tax Base multiplied
by the rentable area of the Building.

         During any partial calendar year during the term, Estimated Taxes and
Expenses will be estimated on a full-year basis. After the close of each
calendar year, Landlord will give Tenant written notice of Estimated Taxes and
Expenses for the ensuing calendar year. On or before the first day of each month
during the ensuing calendar year (or each month of the term, if a partial
calendar year), Tenant wilt pay to Landlord 1/12 of the product of Tenant's
Share multiplied by the Estimated Taxes and Expenses for such calendar year;
however, if such written notice is not given on or before January 1, Tenant will
continue to make monthly payments on the basis of the prior year's Estimated
Taxes and Expenses until the month after such written notice is given, at which
time Tenant will commence making monthly payments based upon the revised
Estimated Taxes and Expenses. In the month Tenant first makes a payment based
upon the revised Estimated Taxes and Expenses, Tenant will pay to Landlord for
each month which has elapsed



                                       9.
<PAGE>

since January 1 the difference between the amount payable based upon the revised
Estimated Taxes and Expenses and the amount payable based upon the prior year's
Estimated Taxes and Expenses. If at any time or times it reasonably appears to
Landlord that the actual Operating Expenses and Real Estate Taxes for any
calendar year will vary from the Estimated Taxes and Expenses for such calendar
year, Landlord may, by written notice to Tenant, revise the Estimated Taxes and
Expenses for such calendar year, and subsequent payments by Tenant in such
calendar year will be based upon such revised Estimated Taxes and Expenses.

         5.5      ANNUAL SETTLEMENT.

         Within 120 days after the end of each calendar year or as soon after
such 120-day period as practicable, Landlord will deliver to Tenant a statement
of amounts payable by Tenant under SECTION 5.1, for such calendar year prepared
and certified by Landlord (the "ANNUAL EXPENSE STATEMENT"). If the Annual
Expense Statement shows an amount owing by Tenant that is less than the
Estimated Taxes and Expense payments previously made by Tenant for such calendar
year, the excess will be held by Landlord and credited against the next payment
of Rent; however, if the term has ended and Tenant was not in default at its
end, Landlord will refund the excess to Tenant within 60 days of the date of the
Annual Expense Statement. If the Annual Expense Statement shows an amount owing
by Tenant that is more than the Estimated Takes and Expense payments previously
made by Tenant for such calendar year, Tenant will pay the deficiency to
Landlord within ten (10) days after the delivery of such statement.

         Each Annual Expense Statement provided by Landlord under this SECTION
5.5 shall be conclusive and binding upon Tenant unless within sixty (60) days
after receipt thereof, Tenant shall notify Landlord that it disputes the
correctness of the Annual Expense Statement, specifying the respects in which
the Annual Expense Statement is claimed to be incorrect. Tenant, at its expense,
shall then have the right to audit Landlord's books and records relating to the
Annual Expense Statement. Pending determination of the dispute, Tenant shall pay
within ten (10) days from notice any amounts due from Tenant in accordance with
the Annual Expense Statement, but such payment shall be without prejudice to
Tenant's position.

         5.6      FINAL PRORATION.

         If this Lease ends on a day other than the last day of a calendar year,
the amount of increase (if any) in the Operating Expenses and Real Estate Taxes
payable by Tenant applicable to the calendar year in which this Lease ends will
be calculated on the basis of the number of days of the term falling within such
calendar year, and Tenant's obligation to pay any increase or Landlord's
obligation to refund any overage will survive the expiration or other
termination of this Lease.

                                SECURITY DEPOSIT

         6.1      AMOUNT OF DEPOSIT.

         Tenant, contemporaneously with the execution of this Lease, has
deposited with Landlord the sum of $45,346.66 (the "SECURITY DEPOSIT") (the
equivalent of two month's rent for the entire



                                      10.
<PAGE>

Demised Premises), the receipt of which is hereby acknowledged by Landlord. The
Security Deposit shall be held by Landlord, without liability for interest, as
security for all of the terms, covenants, and conditions of the Lease to be kept
and performed by Tenant during the term hereof. On the first anniversary of the
Lease Commencement Date, provided Tenant delivers to Landlord certified
financial statements and income statements indicating that Tenant has the same
net worth .it had as of the Lease Commencement Date, and that in its most
recently completed fiscal year and most recently completed fiscal quarter it had
a positive net income, Landlord shall return one-half of the Security Deposit,
together with interest thereon at the rate of 3.4(degree)l(degree) per annum.

         6.2      USE AND RETURN OF DEPOSIT.

         If at any time during the term of this Lease any Rent shall be overdue
and unpaid, or any other sum payable to Landlord by Tenant hereunder shall be
overdue and unpaid, Landlord may (but shall not be required to) appropriate any
portion of the Security Deposit to the payment of any such overdue Rent or other
sum. In the event of the failure of Tenant to keep and perform any of the terms,
covenants and conditions of this Lease, then Landlord at its option may
appropriate and apply the entire Security Deposit, or so much thereof as may be
necessary, to compensate Landlord for all loss or damage sustained or suffered
by Landlord due to such breach on the part of Tenant. Should the entire Security
Deposit, or any portion thereof, be appropriated and applied by Landlord for
payment of overdue Rent or other sums due and payable to Landlord by Tenant
hereunder, then Tenant shall, upon, the written demand of Landlord, forthwith
remit to Landlord a sufficient amount in cash to restore said security to the

                                    ARTICLE 1
                                DEMISED PREMISES

         1.1 AGREEMENT TO LEASE.

         Landlord does hereby lease to Tenant and Tenant does hereby lease from
Landlord, for the term and upon the conditions hereinafter provided, the
following space (the "DEMISED PREMISES")in the building located at 45025
Aviation Drive, Dulles, VA 20166 (the "BUILDING"):

             Approximately 10,558 square feet of rentable area (the
             "Demised Premises"), on the First Floor of the building (Suit
             120) located at 45025 Aviation Drive, Dunes VA 20166 (the
             "BUILDING"), as shown on the plan attached hereto as Exhibit A.

         The real property on which the Building is located, together with the
surrounding real property and parking area, Plot C-7-4, are collectively
referred to herein as the "REAL PROPERTY."

         The Building and the Real Property are sometimes collectively referred
to herein as the "PROJECT."

         1.2 USE OF DEMISED PREMISES.

         Tenant will use and occupy the Demised Premises solely for general
office purposes and uses incident thereto in accordance with the certificate of
occupancy and applicable zoning regulations, and for no other purpose. Tenant
will not use or occupy the Demised Premises for any unlawful, disorderly, or
extra hazardous purpose, and will not manufacture any commodity or prepare or
dispense any food or beverage therein, except for Tenant's personal use in the
Demised Premises. Tenant will comply with all present and future laws,
regulations and governmental requirements of any governmental or public
authority having jurisdiction over the Demised Premises applicable to Tenant's
business. .

         Landlord represents and warrants to Tenant that the Building presently
complies with all applicable federal, state and local laws, ordinances,
regulations, rules and requirements of any governmental authority having
jurisdiction, including the Americans With Disabilities Act of 1990, as amended
(collectedly, "APPLICABLE LAWS").


<PAGE>

         Tenant, at Tenant's sole expense, shall make, or cause to be made,
all necessary installations, repairs, replacements and alterations to the
Demised Premises that are required to comply with any and all Applicable Laws
if: (i) the failure to so comply relates to the initial leasehold
improvements to the Demised Premises being made by Tenant (and not the
condition of the Building or Demised Premises prior to any construction by
Tenant) or any Alterations to the Demised Premises made by Tenant or on
Tenant's behalf; or (ii) such compliance is required as a result of Tenant's
specific use of the Demised Premises.

         1.3 USE OF COMMON AREAS.

         As used in this Lease, the term "COMMON AREAS" means, without
limitation, the hallways, entryways, stairs, elevators, driveways, walkways,
terraces, docks, loading areas, restrooms, trash facilities, and all other areas
and facilities in the Project that are provided and designated from time to time
by Landlord for the general nonexclusive use and convenience of Tenant with
Landlord and other tenants of the Building and their respective employees,
invitees, licensees, or other visitors. Landlord grants Tenant, its employees,
invitees, licensees, and other visitors a nonexclusive license for the term to
use the Common Areas in common with others entitled to use the Common Areas,
subject to the terms and conditions of this Lease. Without advance written
notice to Tenant, and without any liability to Tenant in any respect, provided
Landlord will take no action permitted under this SECTION 1.3 in such a manner
as to materially impair or adversely affect Tenant's substantial benefit and
enjoyment of the Demised Premises, Landlord will have the right to:

             (a) Close off any of the Common Areas to whatever extent required
in the opinion of Landlord and its counsel to prevent a dedication of any of the
Common Areas or the accrual of any rights by any person or the public to the
Common Areas;

             (b) Temporarily close any of the Common Areas for maintenance,
alteration, or improvement purposes; and

             (c) Change the size, use, shape, or nature of any Common Areas,
including erecting additional buildings on the Common Areas, expanding the
existing Building or other buildings to cover a portion of the Common Areas,
converting Common Areas to a portion of the Building or other buildings, or
converting any portion of the building (excluding the Demised Premises) or other
buildings to Common Areas. Upon erection of any additional buildings or change
in Common Areas, the portion of the Project upon which buildings or structures
have been erected will no longer be deemed to be a part of the Common Areas.

         1.4 USES RESERVED EXCLUSIVELY TO LANDLORD.

         As between Landlord and Tenant, Landlord retains unto itself the sole
and exclusive use of the roof, the exterior walls and the Common Areas of the
Building.

         The term "REAL ESTATE TAXES" shall include all taxes and assessments,

         "Real Estate Taxes" shall not include: (a) any gross receipts, capital,

at the specific request of Tenant, Tenant shall be solely responsible for the
payment of such tax.

         The net amount of any refund or credit in Real Estate Taxes obtained by

Landlord in connection with obtaining such refund or credit and not previously
recovered by Landlord as an Operating Expense) shall be passed through one
hundred percent (100%) to Tenant and all other tenants, pro-rata in accordance
with their respective proportionate shares of property taxes.

         5.4 ESTIMATED PAYMENTS.

         During each calendar year or partial calendar year in the term, in
addition to monthly Rent, Tenant will pay to Landlord on the first day of each
month an amount equal to 1/12 of the product of Tenant's Share multiplied by the
"ESTIMATED TAXES AND EXPENSES" (defined below) for such calendar year.


<PAGE>


         "Estimated Taxes and Expenses" for any calendar year means Landlord's
reasonable estimate of Operating Expenses and Real Estate Taxes for such
calendar year, less the product of the Expense Base and the Tax Base multiplied
by the rentable area of the Building.

         During any partial calendar year during the term, Estimated Taxes and
Expenses will be estimated on a full-year basis. After the close of each
calendar year, Landlord will give Tenant written notice of Estimated Taxes and
Expenses for the ensuing calendar year. On or before the first day of each month
during the ensuing calendar year (or each month of the term, if a partial
calendar year), Tenant will pay to Landlord 1/12 of the product of Tenant's
Share multiplied by the Estimated Taxes and Expenses for such calendar year;
however, if such written notice is not given on or before January 1, Tenant will
continue to make monthly payments on the basis of the prior year's Estimated
Taxes and Expenses until the month after such written notice is given, at which
time Tenant will commence making monthly payments based upon the revised
Estimated Taxes and Expenses. In the month Tenant first makes a payment based
upon the revised Estimated Taxes and Expenses, Tenant will pay to Landlord for
each month which has elapsed since January 1 the difference between the amount
payable based upon the revised Estimated Taxes and Expenses and the amount
payable based upon the prior year's Estimated Taxes and Expenses. If at any time
or times it reasonably appears to Landlord that the actual Operating Expenses
and Real Estate Taxes for any calendar year will vary from the Estimated Taxes
and Expenses for such calendar year, Landlord may, by written notice to Tenant,
revise the Estimated Taxes and Expenses for such calendar year, and subsequent
payments by Tenant in such calendar year will be based upon such revised
Estimated Taxes and Expenses.

         5.5 ANNUAL SETTLEMENT.

         Within 120 days after the end of each calendar year or as soon after
such 120-day period as practicable, Landlord will deliver to Tenant a statement
of amounts payable by Tenant under SECTION 5.1 for such calendar year prepared
and certified by Landlord (the "ANNUAL EXPENSE STATEMENT"). If the Annual
Expense Statement shows an amount owing by Tenant that is less than the
Estimated Taxes and Expense payments previously made by Tenant for such calendar
year, the excess will be held by Landlord and credited against the next payment
of Rent; however, if the term has ended and Tenant was not in default at its
end, Landlord will refund the excess to Tenant within 60 days of the date of the
Annual Expense Statement. If the Annual Expense Statement shows an amount owing
by Tenant that is more than the Estimated Taxes and Expense payments previously
made by Tenant for such calendar year, Tenant will pay the deficiency to
Landlord within ten (10) days after the delivery of such statement.

         Each Annual Expense Statement provided by Landlord under this
SECTION 5.5 shall be conclusive and binding upon Tenant unless within sixty
(60) days after receipt thereof, Tenant shall notify Landlord that it
disputes the correctness of the Annual Expense Statement, specifying the
respects in which the Annual Expense Statement is claimed to be incorrect.
Tenant, at its expense, shall then have the right to audit Landlord's books
and records relating to the Annual Expense Statement. Pending determination
of the dispute, Tenant shall pay within ten (10) days from notice any amounts
due from Tenant in accordance with the Annual Expense Statement, but such
payment shall be without prejudice to Tenant's position.

<PAGE>


         5.6 FINAL PRORATION.

         If this Lease ends on a day other than the last day of a calendar year,
the amount of increase (if any) in the Operating Expenses and Real Estate Taxes
payable by Tenant applicable to the calendar year in which this Lease ends will
be calculated on the basis of the number of days of the term falling within such
calendar year, and Tenant's obligation to pay any increase or Landlord's
obligation to refund any overage will survive the expiration or other
termination of this Lease.

                                SECURITY DEPOSIT

         Tenant, contemporaneously with the execution of this Lease, has
deposited with Landlord the sum of $16.716.83 (the "SECURITY DEPOSIT") (the

Landlord, without liability for interest, as security for all of the terms,
covenants, and conditions of the Lease to be kept and performed by Tenant during
the term hereof.

         6.2 USE AND RETURN OF DEPOSIT.

         If at any time during the term of this Lease any Rent shall be overdue
and unpaid, or any other sum payable to Landlord by Tenant hereunder shall be
overdue and unpaid, Landlord may (but shall not be required to) appropriate any
portion of the Security Deposit to the payment of any such overdue Rent or other
sum. In the event of the failure of Tenant to keep and perform any of the terms,
covenants and conditions of this Lease, then Landlord at its option may
appropriate and apply the entire Security Deposit, or so much thereof as may be
necessary, to compensate Landlord for all loss or damage sustained or suffered
by Landlord due to such breach on the part of Tenant. Should the entire Security
Deposit, or any portion thereof, be appropriated and applied by Landlord for
payment of overdue Rent or other sums due and payable to Landlord by Tenant
hereunder, then Tenant shall, upon the written demand of Landlord, forthwith
remit to Landlord a sufficient amount in cash to restore said security to the
original sum deposited, and Tenant's failure to do so within five (5) days after
receipt of such demand shall constitute a breach of this Lease. Should Tenant
comply with all of said terms, covenants and conditions and promptly pay all of
the Rent as it becomes due, and all other sums payable to Landlord by Tenant
hereunder, the Security Deposit shall be returned in full to Tenant at the end
of the term of this Lease, or upon the earlier termination of this Lease,
together with interest thereon at the rate of 3.4% per annum.

         6.3 TRANSFER OF DEPOSIT.

         Landlord may deliver the Security Deposit to the transferee of
Landlord's interest in the Demised Premises, in the event that such interest be
transferred, and upon delivery of notice from such transferee to Tenant
acknowledging receipt thereof Landlord shall be discharged from any further
liability with respect to the Security Deposit.


<PAGE>


         6.4 NO LIABILITY OF MORTGAGEE.

         Tenant shall not be entitled to look to the mortgagee, as mortgagee,
mortgagee in possession, or successor in title to the Demised Premises, for
accountability for any Security Deposit required by Landlord hereunder, unless
said sums have actually been received by said mortgagee as security for Tenant's
performance of this Lease.

                                    ARTICLE 7

of the Demised Premises to be used or occupied by others, without the prior
written consent of Landlord in each instance, which consent shall not be
unreasonably withheld or unreasonably delayed beyond thirty (30) days from
Tenant's request. Any assignment or sublease in violation of this ARTICLE 7 will
be void. If this Lease is assigned, or if the Demised Premises or any part of
the Demised Premises are subleased or occupied by anyone other than Tenant,
Landlord may, after default by Tenant, collect Rent from the assignee,
subtenant, or occupant, and apply the net amount collected to Rent.

             (b) Notwithstanding the provisions of Section 7.1(a), Tenant may

legal entities such as limited liability companies, partnerships, etc.)
resulting from the merger or consolidation with or into Tenant, or to any person
or entity which acquires all the assets of Tenant as a going concern of the
business that is being conducted on the Premises; provided, that Tenant notifies
Landlord of any such assignment or sublease and promptly supplies Landlord with
any documents or information reasonably requested by Landlord regarding such
assignment or sublease. "Control" as used in this Section 7.1(b) shall mean the
possession, direct or indirect, of the power to direct or cause the direction of
the management and policies of a person or entity.

             (c) No assignment, sublease, occupancy, or collection will be
deemed (1) a waiver of the provisions of this SECTION 7.1; (2) the acceptance of
the assignee, subtenant, or occupant as Tenant; or (3) a release from the
further performance by Tenant of its covenants and obligations contained in this
Lease. The consent by Landlord to an assignment or sublease will not be
construed to relieve Tenant from obtaining Landlord's prior written consent in
writing to any further assignment or sublease. No permitted subtenant may assign
or encumber its sublease or further sublease all or any portion of its subleased
space, or otherwise permit the subleased space or any part of its subleased
space to be used or occupied by others, without Landlord's prior written consent
in each instance.

Landlord will have the right to require Tenant to pay to Landlord a sum equal to
the amount by which the rent to be paid by any assignee or sublessee exceeds the
rent then payable under this Lease, after deducting from the amount payable by
any assignee or sublessee all reasonable costs and expenses incurred by Tenant
in obtaining the assignee or sublessee, including advertising and marketing,
legal fees, and costs associated with the preparation of the space for the
assignee or sublessee.

of any corporate Tenant or subtenant of this Lease (other than as part of an
initial public offering), or a majority of the total interest in any partnership

            TENANT'S CARE OF THE DEMISED PREMISES, BUILDING RULES AND
                        REGULATIONS, AND LANDLORD ACCESS

         10.1 MAINTENANCE AND SURRENDER OF DEMISED PREMISES.

         Tenant, at its sole cost and expense, shall keep the Demised Premises
(including all improvements, fixtures and all other property contained in the
Demised Premises) in a neat, safe, and clean condition, and in good order and
repair, and will surrender the Demised Premises at the end of the term in as
good order and condition as they were at the commencement of the term, except
for reasonable wear and tear. Tenant shall not commit or suffer to be committed
any waste upon the Demised Premises or any nuisance or other act or thing which
may disturb the quiet enjoyment or interfere with, inhibit or preclude any
permitted use of any other tenant in the Building or any person outside the
Building.

         10.2 TENANT EQUIPMENT.

         Maintenance and repair of equipment serving only the Demised Premises,
such as kitchen fixtures, separate air conditioning equipment, or any other type
of special equipment, whether installed by Tenant or by Landlord on behalf of
Tenant, shall be the sole responsibility of Tenant, and Landlord shall have no
obligation in connection therewith.

         10.3 REMOVAL OF FIXTURES AND ALTERATIONS UPON END OF LEASE.

         On or prior to the end of the term, Tenant shall remove from the

         Tenant will not conduct or permit to be conducted any activity or place
any equipment in or about the Demised Premises, which will, in any way, increase
the rate of insurance premiums on the Building or the Real Property. If any
increase in the rate of insurance is stated by any insurance company or by the
applicable Insurance Rating Bureau to be due to any activity or equipment in or
about the Demised Premises, such statement shall be conclusive evidence that the
increase in such rate is due to Tenant's activity or equipment and, as a result
thereof, Tenant shall be liable for such increase and shall reimburse Landlord
therefor, within ten (10) days of receipt of written notice, and said sum shall
be deemed to be Additional Rent.

         10.5 COMPLIANCE WITH BUILDINGS RULES AND REGULATIONS.

         Tenant, its agents and employees shall abide by and observe the rules
and regulations attached hereto and made a part hereof as EXHIBIT B and such
other rules and regulations as may be promulgated from time to time by Landlord
for the operation and maintenance of the Building, the Real Property and the
Project, provided that the same are not inconsistent with the provisions of this
Lease and Tenant is given not less than thirty (30) days notice thereof. Nothing
contained in this Lease shall be construed to impose upon Landlord any duty or
obligation to enforce such rules and regulations, or the terms, conditions or
covenants contained in any other lease, as against any other tenant, and
Landlord shall not be liable to Tenant for violation of the same by any other
tenant, its employees, agents, or invitees. Notwithstanding the foregoing,
Landlord covenants and agrees to enforce all rules and regulations in a uniform
and nondiscriminatory manner. In the event of any conflicts between the rules
and regulations and the provisions of this Lease, the provisions of this Lease
shall control.

         10.6 MISCELLANEOUS COVENANTS AND AGREEMENTS.

         Tenant further agrees that:

         No sign, advertisement or notice shall be inscribed, painted or affixed

style as the Landlord shall reasonably approve.

         Landlord shall have the right to prescribe the weight, and method of
installation and position of safes or other heavy items forming part of the
Tenant Remove Items. Tenant shall not install any Tenant Remove Items that will
place a load upon any floor exceeding the load per square foot area which such
floor was designed to carry.

         All damage done to the Building by taking in or removing any Tenant
Remove Items, or due to its being in the Demised Premises, shall be repaired at
the expense of Tenant.

         No freight, furniture or other bulky matter of any description shall be
received into the Building or carried in the elevators, except as approved by
Landlord. All moving of Tenant


<PAGE>


Remove Items shall be under the direct control and supervision of the Landlord,
who shall, however, not be responsible for any damage to or charges for moving
same, but shall fully cooperate with Tenant in scheduling same. Provided Tenant
furnishes Landlord with at least two week's prior written notice of Tenant's
move to the Demised Premises, Tenant shall have the exclusive right to use the
freight elevator during the weekend that it moves into the Demised Premises.

         10.7 LANDLORD ENTRY FOR REPAIRS AND INSPECTION.

         Tenant shall permit Landlord, or its representative(s), to enter the

hour notice to Tenant; or at such other times and with such shorter or no notice
as may be required in the event of an emergency, to examine and inspect same,
and to make such alterations and/or repairs as in the judgement of Landlord may
be deemed necessary, or to exhibit the same to prospective tenants, purchasers
or mortgagees. If, in an emergency, it shall become necessary to make promptly
any repairs or replacements required to be made by Tenant, then Landlord may, at
its option, proceed forthwith to have such repairs or replacements made and to
pay the cost thereof for Tenant's account. Tenant shall reimburse Landlord for
the cost of such repairs or replacements on demand.

         There shall be no abatement of Rent and no liability by reason of any
injury to or interference with Tenant's business arising from the making of any

amount of such premiums from the date of payment by Landlord until the date of
repayment by Tenant at the Default Rate (as defined in SECTION 14.14).

         11.4 INSURANCE COVERAGE DOES NOT LIMIT TENANT'S LIABILITY.

         Neither the issuance of any insurance policy required under this Lease

Loss is covered by insurance required to be carried by the parties under this

                            CASUALTY AND CONDEMNATION

         13.1 FIRE AND OTHER CASUALTY DAMAGE TO DEMISED PREMISES.

         If the Demised Premises (other than leasehold improvements) shall be
partially damaged by fire or other cause covered by extended coverage insurance,
other than by the fault or neglect of Tenant, Landlord shall as soon as
practicable after such damage occurs (taking into account the time necessary to
effectuate a satisfactory settlement with any insurance company) repair such

any claim that it may have against the condemning authority for compensation for
any fixtures owned by Tenant and for any relocation expenses compensable by
statute. The Rent, however, shall be abated on the date when such title vests in
such governmental authority. If less than a substantial part of the Demised

         14.1 EVENTS OF DEFAULT DEFINED.

         Each of the following events shall be a default ("EVENT OF DEFAULT") of

of the type that is not reasonably capable of being cured within thirty (30)
days, then Tenant shall have such longer cure period in which to cure such
default, provided Tenant commences such cure within thirty (30) days after
written notice thereof by Landlord, and thereafter diligently prosecutes such
cure to completion).

              (d) LEASE ATTACHMENT: The taking of this Lease or the Demised
Premises, or any part thereof, upon execution or by other process of law

         14.2 EVENTS OF DEFAULT JOT AFFECTED BY SECURITY DEPOSIT OR ACCEPTANCE
OF RENT.

         The provisions of this ARTICLE 14 shall apply notwithstanding the
payment by Tenant of a Security Deposit. The receipt by Landlord of payments of
Rent, as such, accruing subsequent to the time of an Event of Default shall not
be deemed a waiver by Landlord of its rights and remedies under this Article 14.

         14.3 REMEDIES UPON EVENT OF DEFAULT.

         Upon the occurrence of an Event of Default, Landlord shall have the
right, at its election, then or at any time thereafter either:

              (a) TERMINATION OF LEASE: To give Tenant written notice of
Landlord's intent to terminate this Lease on the date of the notice or on any

and take possession of all or any part of the Demised Premises, and expel Tenant
and those claiming through Tenant, and remove the property of Tenant and any
other person, either by summary proceedings or by action at law or in equity,
without being deemed guilty of trespass and without prejudice to any remedies
for nonpayment or late payment of Rent or breach of covenant. If Landlord elects
to reenter under this subsection, Landlord may terminate this Lease, or, from
time to time, without terminating this Lease, may relet all or any part of the
Demised Premises as agent for Tenant for such term or terms and at such rental
and upon such other terms and conditions as Landlord may deem advisable, with
the right to make alterations and repairs to the Demised Premises. No such
reentry or taking of possession of the Demised Premises by Landlord shall be
construed as an election on Landlord's part to terminate this Lease unless a
written notice of such intention is given to Tenant under SECTION 14.3(a.), or
unless the termination be decreed by a court of competent jurisdiction at the
request of Landlord.


<PAGE>


              (c) WAIVER OF NOTICE, REDEMPTION. REPOSSESSION AND RESTORATION OF
LEASE: Tenant, on its own behalf and on behalf of all persons claiming through
Tenant, including all creditors, does hereby waive any and all rights and
privileges, so far as its permitted by law, which Tenant and all such persons
might otherwise have under any present or future law (i) to the service of any
notice of intention to reenter which may otherwise be required to be given, (ii)
to redeem the Demised Premises, (iii) to reenter or repossess the Demised
Premises, or (iv) to restore the operation of this Lease, with respect to any
dispossession of Tenant by judgment or warrant of any court, whether such
dispossession, reentry, expiration or termination be by operation of law or
pursuant to the provisions of this Lease.

         14.4 LIABILITY OF TENANT.

         If Landlord terminates this Lease pursuant to SECTION 14.3, Tenant
shall remain liable (in addition to accrued liabilities) for:

(A)  (i) Minimum Rent, Additional Rent and any other sums provided for in this
     Lease until the date this Lease would have expired had such termination not
     occurred; (ii) any and all expenses (including attorneys' fees,
     disbursements and brokerage fees) incurred by Landlord in reentering and
     repossessing the Demised Premises, in curing any Event of Default, in
     painting, altering, repairing or dividing the Demised Premises, in
     protecting and preserving the Demised Premises by use of watchmen and
     caretakers, and in reletting the Demised Premises; and (iii) any and all
     expenses which Landlord may incur during the occupancy of any new tenant;

     LESS:

(B)  The net proceeds of any reletting prior to the date this Lease would have
     expired if it had not been terminated.

     Tenant agrees to pay to Landlord the difference between ITEMS (A) AND (B)
above for each month during the term, at the end of each such month. Any suit
brought by Landlord to enforce collection of such difference for any one month
shall not prejudice Landlord's right to enforce the collection of any difference
for any subsequent month. Tenant's liability shall survive the institution of
summary proceedings and the issuance of any writ of restitution thereunder.

     14.5 LIQUIDATED DAMAGES.

     If Landlord terminates this Lease pursuant to this ARTICLE 14, Landlord
shall have the right, at any time, at its option, to, require Tenant to pay to
Landlord, on demand, as liquidated and agreed final damages in lieu of Tenant's
liability under SECTION 14.4 the rent and all other charges which would have
been payable from the date of such demand to the date when this Lease would have
expired if it had not been terminated, minus the fair rental value of the
Demised Premises for the same period, discounted to present value at a discount
rate equal to five percent (5%) per annum. If the Demised Premises shall have
been relet for all or part of the remaining balance of the term by Landlord
after an Event of Default but before determination of such liquidated damages,
the amount of rent reserved upon such reletting shall be deemed the fair rental
value of the Demised Premises for purposes of the foregoing determination of


<PAGE>


liquidated damages. Upon payment of such liquidated and agreed final damages,
Tenant shall be released from all further liability under this Lease with
respect to the period after the date of demand.

         14.6 ATTORNEYS' FEES.

         In the event Tenant defaults in the performance of any of the terms,
covenants, agreements or conditions contained in this Lease and Landlord places

shall not be bound by any payment in Rent in advance for more than thirty (30)
days or by any amendment or modification of this Lease made subsequent to the

ground or underlying lease, as if such prepayment had not been made. Such
landlord or successor under such ground or underlying lease shall not be bound
by this Lease or any amendment or modification of this Lease unless, prior to

existing lease term. In the event of such exercise, this lease shall be deemed
to be extended for the additional period pursuant to all the terms and
conditions set forth herein, including (but not as a limitation) those
provisions for increase of the base rental set forth in Paragraph 4.1.3. In the
event of exercise of said Option, any funds held by Landlord pursuant hereto
shall continue to be so held subject to the terms and conditions relating to
same.

                3.3 TENANT IMPROVEMENT CONSTRUCTION. The Commencement Date of
this lease shall be delayed until the substantial completion of the tenant
improvements described on Exhibit "A" attached hereto and delivery of possession
to Tenant, if such occurs after the Commencement Date, as follows: if for any
reason Landlord does not substantially complete such construction prior to the
Commencement Date, such failure will not affect the validity of this lease, but
in such case Tenant shall not be obligated to pay rent until such construction
is substantially completed and possession of the premises is delivered to
Tenant. Provided, however, if Landlord shall not have substantially completed
and delivered possession of the premises within sixty (60) days after the
Commencement Date, Tenant may, at Tenant's option, upon notice in writing to
Landlord delivered within ten (10) days after the end of the 60-day period,
cancel this lease. Landlord shall have no liability to Tenant for failure to
substantially complete construction prior to any date or dates. Tenants only
remedy shall be cancellation of the lease.

               Should construction of the tenant improvements be completed to
such an extent as to permit the issuance of a partial certificate of occupancy
by the governing authority, Tenant may occupy the portion of the premises so
permitted prior to (or after) the Commencement Date and shall pay rent for the
occupied portion, prorated in proportion to the number of square feet of
building space occupied, beginning on data of delivery of possession. Rent
adjustments shall be similarly prorated. In no event shall Tenant take
possession prior to satisfaction of the requirements for Tenant's insurance set
forth below.

                3.4 DELIVERY OF POSSESSION. Except as above provided with
respect to construction of Tenant improvements, Tenant shall be entitled to
possession of the premises at noon on the Commencement Date, as defined in
Paragraph 3.1. Tenant may, with approval by Landlord in its sole discretion,
have access to the premises during tenant improvement construction for the
purpose of moving in Tenant-owned furniture, fixtures, equipment and inventory.
This access and the items so moved in shall not in any way impede the
construction of the tenant improvements, nor shall Landlord, its agent,
employees, sub-contractors, or any other person on the premises whether invited
or not invited, be liable for the protection, care or security of Tenant owned
items. This paragraph shall not be construed so as to permit Tenant to occupy
the premises prior to the satisfaction of all requirements for Tenant's
insurance set forth below.

        4.  RENT.  Tenant shall pay to  Landlord,  at the address of Landlord as
herein set forth, the following as rental for the premises:

                4.1 BASE RENTAL. The base rental for the full term hereof shall
be SEVENTY THOUSAND NINE HUNDRED EIGHT AND NO/100THS Dollars ($70,908.00),
payable in monthly installments (basic monthly rental of ONE THOUSAND NINE
HUNDRED SIXTY


                                       2
<PAGE>

NINE AND 67/100THS Dollars ($1,969.67)) in advance on the first day of each
month during the term hereof.

                4.2 OPERATING EXPENSES. Tenant shall pay to Landlord during the
term hereof, in addition to the Bass Rental, Tenant's Share, as hereinafter
defined, of the Operating Expenses, as hereinafter defined, for each year of the
term, in accordance with the following provisions:

                        4.2.1 Tenant's Share, as defined, for purposes of this
Lease Agreement, to be the percentage which is determined by dividing the
approximate square footage of the Leased Premises by the total approximate
square footage of the space contained in the Diagonal Offices Project. It is
understood and agreed that the square footage figures set forth in the Lease
Agreement which Landlord and Tenant agree are reasonable and shall not be
subject to revision except in connection with an actual change in the size of
the Premises or a change in the space available for lease in the Diagonal
Offices Project. Total square footage in the Diagonal Offices Project is 16,844
square feet, and Tenant's share is fourteen and eight tenths percent (14.80).

                        4.2.2 Operating Expenses for the first year of the
initial term are estimated to be $3.00 per rentable square foot. During said
year, Tenant shall make estimated monthly payments of $622.00 as Tenant's share
of Operating Expanses.

                        4.2.3 Tenant's share of the Operating Expenses for the
first and last years of the lease term shall be prorated according to that
portion of such year as to which Tenant is responsible for a share of such
expenses.

                        4.2.4 "Operating Expenses" is defined, for purposes of
this Lease Agreement, to include all costs, if any, incurred by Lessor in the
exercise of its reasonable discretion, for:

                        (a) The operation, repair, maintenance, and replacement,
in neat, clean, safe, good order and condition, of the Diagonal Offices Project,

walkways, stairways, parkways, driveways, landscaped areas, striping, bumpers,
irrigation systems, Common Area lighting facilities, building exteriors and
roofs, fences and gates;

                                (ii) All heating, air conditioning, plumbing,
electrical systems, ADA issues, life safety equipment, telecommunication and
other equipment used in common by, or for the benefit of, tenants or occupants
of the Diagonal Offices Project, including tenant directories, fire detection
systems including sprinkler system maintenance and repair.

                        (b) Trash disposal, janitorial for the common areas and
security services;


                                       3
<PAGE>

                        (c) Any other service which may be provided by Landlord
that is elsewhere in this Lease Agreement stated to be an "Operating Expense";

                        (d) The cost of the premiums for the liability and
property insurance policies to be maintained by Landlord under Paragraph 19
hereof;

                        (e) The amount of the real property taxes to be paid by
Landlord under Paragraph 5 hereof;

                        (f) The cost of water, sewer, gas, electricity, and
other publicly mandated services to the Diagonal Offices Project;

                        (g) Labor, salaries and applicable fringe benefits and
costs, materials, supplies and tools, used in maintaining and/or cleaning the
Diagonal Offices Project and accounting and a management fee attributable to the
operation of the Diagonal Offices Project;

                        (h) Replacing and/or adding improvements mandated by any
governmental agency and any repairs or removals necessitated thereby amortized
over its useful life according to the Federal income tax regulations or
guidelines for depreciation thereof (including interest on the unamortized
balance as is then reasonable in the judgment of Landlord's accountants);

                        (i) Replacements of equipment or improvements that have
a useful life for depreciation purposes according to Federal income tax
guidelines of five (5) years or less, as amortized over such life.

                        4.2.5 Operating Expenses shall not include the costs of
replacements of equipment or improvements that have a useful life for Federal
income tax purposes in excess of five (5) years unless it is of the type
described in Paragraph 4.2.4(h) , in which case their cost shall be included as
above provided.

                        4.2.6 Operating Expenses shall not include any expenses
paid by any tenant directly to third parties, or as to which Landlord is
otherwise reimbursed by any third party, other tenant, or by insurance proceeds.

                        4.2.7 Each January 1st, and annually thereafter,
Tenant's Share of any increase in Operating Expenses shall be payable by Tenant
within ten (10) days after a reasonably detailed statement of actual expenses is
presented to Tenant by Landlord. At Landlord's option, however, an amount may be
estimated by Landlord from time to time in advance of Tenant's Share of the
increase in Operating Expenses; and the same shall be payable monthly or
quarterly, as Landlord shall designate, during each calendar year subsequent to
the year in which the lease is executed, on the same day as the Base Rental is
due hereunder. In the event that Tenant pays Landlord's estimate of Tenant's
Share of the increase in Operating Expenses as aforesaid, Landlord shall deliver
to Tenant within sixty (60) days after the expiration of each subsequent year a
reasonably detailed statement showing Tenant's Share of the actual Operating
Expense increase incurred during such year. If Tenant's payments under this
paragraph 4.2.7 during said subsequent year exceed Tenants Share as indicated on
said statement, Tenant shall be entitled to credit the amount of such
overpayment against Tenant's


                                       4
<PAGE>

Share of Operating Expenses next falling due. If Tenant's payments under this
paragraph during said subsequent year were less than Tenant's Share as indicated
on said statement, Tenant shall pay to Landlord the amount of the deficiency
within ten (10) days after delivery by Landlord to Tenant of said statement.
Landlord and Tenant shall forthwith adjust between them the cash payment any
balance determined to exist with respect to that portion of the last year for
which Tenant is responsible as to Operating Expenses, notwithstanding that the
Lease term may have terminated before the end of such year.

                4.3 ESCALATION OF BASE RENTAL.

                        4.3.1 On March 15,1995, the base rental payable by
Tenant shall be increased by five percent (5%).

                        4.3.2 Landlord and Tenant agree that the Base Rental
increase shall be calculated on the Base Rental of $9.50 per square foot.

                4.4 PRIVATE SECURITY SERVICE. Landlord may, in its sole
discretion, engage a private security service, as an independent contractor, to
patrol an area which includes the premises. If Landlord does so employ a private
security service, the cost thereof shall be treated in the same manner as
Operating Expense and paid by Tenant as Additional Rent under the same
provisions as are applicable to Operating Expense.

               Landlord shall have absolutely no obligation to engage a private
security service and shall not be liable for any damages or loss which might
have been averted had a private security service been engaged. If Landlord does
engage a private security service, Landlord shall not be liable for any damages
or loss which may result from actions, inactions, non-performance or quality of
performance by the security service. If the Tenant desires a higher level of
security services than Landlord provides, or wishes to obtain an agreement that
there will be liability for actions, inactions, non-performance or quality of
performance by a security service, Tenant may itself engage such security
service as Tenant chooses, at Tenant's sole expense.

               Nothing herein shall limit any action by Tenant against any
person or entity providing private security service, provided that Landlord
shall not be party to, or liable for any judgment entered in such an action, as
a defendant, cross defendant, third-party defendant, or otherwise. Tenant shall
indemnify Landlord against any loss, liability or claim arising out of any
action brought by tenant against any person or entity providing private security
service. The obligation to indemnify shall include payment of Landlord's
attorneys' fees incurred in connection with the claim covered by the indemnity
and in enforcing the obligation to indemnify.

                4.5 LATE CHARGES. Tenant will pay a late charge equal to five
percent of any monthly rental payment or other payment not paid when due, which
payment shall be in addition to any interest elsewhere provided for.

                4.6 SECURITY DEPOSIT. Landlord acknowledges receipt of the sum
of THREE THOUSAND NINE HUNDRED THIRTY NINE AND 34/100THS Dollars ($3,939.34)
paid by Tenant upon the execution hereof, to be retained by Landlord as security
for the performance of all of the terms and conditions of this lease Agreement
to be performed by Tenant including


                                       5
<PAGE>

payment of all rental due under the terms hereof. Landlord shall not owe Tenant
any interest on the deposit. At Landlord's election, deductions may be made by
Landlord from the amount so retained for the reasonable cost of repairs to the
premises which should have been performed by Tenant, for any rental payment or
other sum delinquent under the terms hereof, and for any sum used by Landlord in
any manner to cure any default in the performance of Tenant under the terms of
this lease. In the event deductions are so made during the rental term, upon
notice by Landlord, Tenant shall redeposit such amounts so expended so as to
maintain the security deposit in the amount as herein provided for, within 10
days after receipt of such written demand from Landlord. Nothing herein
contained shall limit the liability of Tenant as to any repairs or maintenance
of the premises; and nothing herein shall limit the obligation of Tenant
promptly to pay all sums otherwise due under this lease and to comply with all
the terms and conditions hereof. The security deposit, less any sums withheld by
Landlord pursuant to the terms hereof, shall be repaid to Tenant within sixty
days after the data of termination of the lease.

                4.7 PRORATION OF RENT FOR PARTIAL MONTHS. If the lease term
begins on other than the first day of a month, base rent and additional rent
from such date until the first day of the next succeeding calendar month shall
be prorated on the basis of the actual number of days in such calendar month and
shall be payable in advance. If the lease term terminates on other than the last
day of the calendar month, rent from the first day of such calendar month until
such termination date shall be prorated on the basis of the actual number of
days in such month, and shall be payable in advance.

        5. TAXES. The Landlord will pay all real property taxes which may be
levied or assessed against the property of which the leased premises are a part.
Tenant shall be responsible for and shall pay any and all taxes or assessments
levied or assessed against any furniture, fixtures, equipment, and items of a
similar nature installed or located in or about the leased premises by Tenant.

        6. SERVICES PROVIDED BY LANDLORD. Landlord agrees, without extra charge
except as provided below, during the period Tenant shall occupy the premises
under the terms hereof, and in accordance with standards from time to time
prevailing for a office building in the City of Longmont:

                (a) to furnish such heated or cooled air to the premises each
business day other than Saturdays, Sundays and legal holidays from 8:00 a.m. to
8:00 p.m., as may in the judgment of Landlord be reasonable required for the
comfortable use and occupation of the premises;

                (b) to provide window washing as may in the judgment of Landlord
be reasonably required; and

                (c) to cause electric current to be supplied for lighting the
premises and public halls and ordinary business office use.

        It is understood that Tenant shall use such electric current as shall be
supplied by Landlord only for ordinary lighting and ordinary office equipment,
necessary for normal business use, as reasonably determined by Landlord, unless
the prior written approval of


                                       6
<PAGE>

Landlord is obtained. Tenant shall pay on demand to Landlord for electric
current for any other purpose, including without limitation, the operation of
heavy duty accounting equipment and copy equipment and the operation of ordinary
office equipment in such numbers that more electric current is required than is
necessary for normal business office use as determined by Landlord. Tenant shall
also pay Landlord for Landlord's cost of acquiring and installing meters or
other measuring devices, if deemed necessary by Landlord for determining the
amount of electric current used by Tenant. The amount to be paid by Tenant for
use of electric current shall be determined by data from meters or other
measuring devices satisfactory to Landlord based upon charges determined by
Landlord, unless the amount to be paid is otherwise agreed upon by Landlord and
Tenant. Before using more electric current than is necessary for normal business
office use, Tenant shall ascertain from Landlord the maximum amount of electric
current which can be safely used in the premises, taking into account the
capacity of the electric wiring and other electric facilities in the building
and the premises, as well as the needs of other tenants in the Building, and
Tenant shall not use more electric current than the maximum amount which can be
safely used in the premises. Landlord's consent to Tenant's use of anything
using more electric current than is necessary for normal business office use
shall not relieve Tenant from its obligation not to use more electric current
than that which Landlord states is the maximum amount which can be safely used
in the premises.

        7. INTERRUPTION OR DISCONTINUANCE OF LANDLORD'S SERVICES. Tenant agrees
that Landlord shall not be liable for failure to supply any such heating, air
conditioning, or electric current during any period Landlord is unable to
furnish such services or current and Landlord uses reasonable diligence to
supply such services or current, it being understood that Landlord reserves the
right to discontinue temporarily such services, or any of them, or such current
at such times as may be necessary by reason of accident, unavailability of
employees, repairs, alterations or improvements, or whenever by reason of
strikes, lockouts, riots, acts of God or any other happening, beyond control of
Landlord. Landlord's obligations to furnish services or current shall be
conditioned upon the availability of adequate energy sources. Landlord shall
have the right to reduce heating, cooling or lighting within the premises and in
the public areas in the Building and the right to enter upon the premises at all
reasonable times in order to make such repairs, alterations and adjustments as
shall be necessary in order to comply with the provisions of any mandatory or
voluntary fuel or energy saving allocation or similar statute, regulation or
program. Tenant further agrees that, if any payment of rent as herein provided
shall remain unpaid for more than Ten (10) days after it shall become due,
Landlord may, without notice to Tenant, discontinue furnishing heating, air
conditioning, and electric current, or any of them, until all arrears of rent
shall have been paid in full, and Landlord shall not be liable for damages to
person or property for any such discontinuance, nor shall such discontinuance in
any way be construed as an eviction of tenant or cause an abatement of rent or
operate to release Tenant from any of the Tenants obligations hereunder.

        8. HOLDING OVER. If, after expiration of the term of this lease, Tenant
shall remain in possession of the premises and continue to pay rent without a
written agreement as to such possession, then Tenant shall be deemed a
month-to-month Tenant and the rental rate during such holdover tenancy shall be
equivalent to one and one-half times the monthly rental paid for the last month
of tenancy under this lease. Such month-to-month tenancy may be


                                       7
<PAGE>

terminated by the Landlord at noon on any day which is more than twenty-nine
(29) days after date of delivery of Landlord's written notice of termination to
Tenant.

        9. MODIFICATIONS OR EXTENSIONS. No holding over by Tenant shall operate
to renew or extend this lease without the written consent of Landlord. No
modification of this lease shall be binding unless endorsed hereon or otherwise
written and signed by the respective parties.

        10. ALTERATIONS BY LANDLORD. Tenant shall permit Landlord to enter the
premises to examine and inspect the same and make such repairs,, additions or
alterations as Landlord may deem necessary or proper for the safety, improvement
or preservation thereof and of the Building, and it is expressly understood that
Landlord shall at all times have the right at its election to make any such
alterations or changes either to the premises or to other portions of the
Building as it may from time to time deem necessary or desirable, as long as
such alterations and changes do not unreasonably interfere with Tenant's use and
occupancy of the premises.

        11. ALTERATIONS BY TENANT. Tenant shall make no alterations,
decorations, improvements or additions to the premises without first obtaining
the written consent of Landlord; and all said alterations, additions or
improvements made by either party whether or not at the expense of Tenant,
including carpeting, shall be deemed a part of the real estate and the property
of Landlord and shall remain upon and be surrendered with said premises as a
part thereof without molestation, disturbance or injury at the end of said term
whether by lapse of time or otherwise.

        12. MECHANIC'S LIENS. Tenant shall pay all costs for construction done
by it or caused to be done by it on the premises as permitted by this lease.
Tenant shall keep the building, other improvements and land of which the
premises are a part free and clear of all mechanic's liens resulting from
construction by or for Tenant. Tenant shall have the right to contest the
correctness or validity of any such lien if, immediately on demand by Landlord,
Tenant deposits with Landlord and/or any appropriate court or title insurance
company a bond or sum of money sufficient to allow issuance of title insurance
against the lien and/or to comply with the statutory requirements for discharge
of the lien found in ss.ss. 38-22-130 and 131, Colorado Revised Statutes, or any
successor statutory provision. Landlord shall have the right to require Tenant's
contractor(s), subcontractors and materialmen to furnish to both Tenant and
Landlord adequate lien waivers on work or materials paid for, in connection with
all periodic or final payments, by endorsement on checks, making of joint
checks, or otherwise, and Landlord shall have the right to review invoices prior
to payment. Landlord reserves the right to post notices on the premises that
Landlord is not responsible for payment of work performed and that Landlord's
interest is not subject to any lien.

        13. SIGNS. It is the Landlord's intent to maintain uniformity of signs.
Tenant shall place no signs on the leased premises without prior written consent
of Landlord. No signs shall be placed on any windows or doors. Landlord will
provide a common directory sign for the Building and Tenant shall be entitled to
a listing on such sign.

        14. MAINTENANCE AND REPAIRS OF THE BUILDING; LANDLORD NOT LIABLE FOR
DAMAGE TO CONTENTS. Landlord shall be responsible for maintenance


                                       8
<PAGE>

and repairs of the structural portions, the roof, the common areas and the
exterior finish of the building (other than glass) on the premises at the sole
cost and expense of Landlord; provided, however, that if any such maintenance or
repairs are necessitated by the acts of Tenant or its employees, agents,
contractors, sub-contractors, licensees, invitees or guests, Tenant shall
reimburse Landlord for the cost of same, as additional rent, to be paid within
10 days after delivery of invoice. All other maintenance, repairs and
replacements within the premises shall be performed by Tenant, at its own
expense, including all necessary maintenance, repairs and replacements to
electrical systems, window or other glass, doors, fixtures, interior
decorations, and all other appliances and appurtenances. Such repairs and
replacements, interior and exterior, ordinary as well as extraordinary, shall be
made promptly, as and when necessary, so that the premises are maintained in
first class condition. All such maintenance, repairs and replacements shall be
in quality and class at least equal to the original work. On default of Tenant
in making such maintenance, repairs or replacements, Landlord may, but shall not
be required to, make such repairs and replacements for Tenant's account, and the
expense shall constitute and be collectable as additional rent, together with
interest thereon as hereinafter provided.

        Notwithstanding the Landlord's obligations elsewhere set forth in this
lease, under no circumstances shall Landlord be liable for damage to the
contents of the building or consequential damages to Tenant resulting from roof
or window leaks or failure, or leakage of any water pipe or gas pipe, failure of
any communications system or alarm, failure or leakage or discharge by any
sprinkler system or other fire suppression system, power surges, power shortages
or outage, sewer failure or sewage backup, or failure or malfunction of any
heating or cooling system. The term "contents" shall include, but shall not be
limited to, improvements made by Tenant, and data bases and other information
stored or contained to computers, hard or floppy disks, tapes, computer chips
and other memory or storage devices. The term "consequential damages" shall
include, but not be limited to, Tenant's inability to perform any contract on
which Tenant is bound, loss of sales, loss of profit, or loss of business
reputation or goodwill.

        15. CONDITION UPON SURRENDER -- RETURN OF KEYS. Tenant shall vacate the
premises in the same condition as when received, ordinary wear and tear
excepted, and shall remove all of Tenant's property, so that Landlord can
repossess the premises not later than noon on the day upon which this lease or
any extension hereof ends, whether upon notice, holdover or otherwise. The
Landlord shall have the same rights to enforce this covenant by ejectment and
for damages or otherwise as for the breach of any other conditions or covenant
of this lease. Upon termination of the lease, Tenant shall deliver to Landlord
keys which operate all locks on the exterior or interior of the premises,
including, without limitation, keys to locks on cupboards and closets. Tenant
shall retrieve all keys to the premises which Tenant has delivered to employees
or others, and include same with the keys delivered to Landlord.

        16. NO WASTE; NO NUISANCE; COMPLIANCE WITH LAWS; RULES AND REGULATIONS.
Tenant shall use the premises for offices and other uses appurtenant thereto.
Tenant shall conform to all present and future laws and ordinances of any
governmental authority having jurisdiction over the premises, and will make no
use in violation of same. No outside storage shall be allowed unless first
approved by Landlord in writing and then only in such areas as are designated as
storage areas by Landlord. Tenant shall not commit or suffer any waste on the
premises. Tenant shall not permit any nuisance to be maintained on the premises


                                       9
<PAGE>

nor permit any disorderly conduct, noise or other activity having a tendency to
annoy or to disturb occupants of any other part of the property of which the
premises are a part and/or of any adjoining property.

        It is further agreed that the following rules and regulations shall be
and are hereby made a part of this Lease and Tenant agrees that its employees
and agents, or any others permitted by Tenant to occupy or enter the premises,
will at all times abide by said rules and regulations and that a default in the
performance and observance thereof shall operate the same as any other default
herein:

                (A) The sidewalks, entries, passages, corridors, stairways and
elevators (if the Building is so equipped) of the Building shall not be
obstructed by Tenant, or its agents or employees, or used for any purpose other
than ingress and egress to and from the premises.

                (B) (i) Furniture, equipment or supplies shall be moved in or

during such hours and in such manner as may be prescribed by Landlord.

                    (ii) No safe or article, the weight of which may, in the
opinion of the Landlord, constitute a hazard or danger to the Building or its
equipment, shall be moved into the premises.

                (C) No furniture shall be placed in front of the Building or in
any lobby or corridor, without the prior written consent of Landlord. Landlord
shall have the right to remove all non-permitted signs and furniture, without
notice to Tenant, at the expanse of Tenant.

                (D) Tenant shall not do or permit anything to be done in the
premises, or bring or keep anything therein, which will in any way increase the
rate of fire insurance on the Building, or on property kept therein, or obstruct
or interfere with the rights of other Tenants, or in any way injure or annoy
them, or conflict with the laws relating to fire, or with any regulations of the
fire department, or with any insurance policy upon the Building or any part
thereof, or conflict with any governmental rules, regulations and ordinances of
the City or its statutes.

                (E) Landlord shall have the right to take all such reasonable
measures as it may deem advisable for the security of the Building or its
occupants, including without limitation (i) the requirements that persons
entering or leaving the Building whether or not during regular working hours,
identify themselves to security personnel, if any, by registration or otherwise,
(ii) establish their right to enter or leave the Building and allow reasonable
security inspection of themselves and their effects, (iii) that Tenant evacuate
itself temporarily from the Building for reasonable drill purposes, (iv) that
Landlord reasonably be permitted to temporarily deny Tenant and its employee,
representatives and invitees access to, and to temporarily close the Building,
(v) deny access to the Building offer regular working hours under such
reasonable rules and regulations as Landlord may prescribe from time to time.

                (F) Water closets and other water fixtures shall not be used for
any purpose than that for which the same are intended, and any damage resulting
to the same from misuse on the part of Tenant, its agents or employees shall be
paid for by Tenant.

        18. NO USE OF PREMISES IN VIOLATION OF INSURANCE POLICIES. Tenant shall
make no use of the premises which would void or make voidable any insurance upon
the premises.

        19. INSURANCE. The Landlord shall keep the property insured throughout
the term of this lease against loss as covered by an "all risk" insurance policy
at the sole expense of the Landlord. To the extent, however, that any use of the
leased premises by Tenant, with or without Landlord's consent, would in any way
tend to increase premiums for such insurance, Tenant agrees to pay additional
monthly rent equal to such increase in insurance premiums paid by Landlord.

               Tenant shall maintain, at the sole expense of the Tenant, the
following insurance throughout the term of this lease:

               Claims for personal injury or property damage under a policy of
general public liability insurance, with such limits as may be reasonably
requested by the Landlord from time to time, but not less than
$300,000.00/$1,000,000.00 in respect of bodily injury; and $300,000.00 for
property damages.

               Against such other hazards and in such amounts as the holder of
any mortgage or deed of host to which the lease is subordinate may require from
time to time.

               If the Tenant requests Landlord to obtain the insurance required
by Tenant, as additional insurance under the Landlord's fire insurance policy,
and if Landlord consents to obtain such insurance, then Tenant shall reimburse
Landlord on a monthly basis for all insurance premiums paid by Landlord for such
insurance coverage required of Tenant.

               19.1 WAIVER OF SUBROGATION. Landlord and Tenant grant to each
other on behalf of any insurer providing fire and extended insurance coverage to
either of them covering the premises, improvements thereon, and contents
thereof, a waiver of any right of subrogation or recovery of any payments of
loss under such insurance, such waiver to be effective so long as


                                       12
<PAGE>

each is empowered to grant such waiver under the terms of its insurance policy,
and to give all necessary notice of such waiver to its insurance carriers.

                19.2 OTHER PROVISIONS REGARDING TENANT'S INSURANCE. All
insurance required of Tenant in this lease shall be effected under enforceable
policies issued by insurers of recognized good financial condition licensed to
do business in this State. At least fifteen (15) days prior to the expiration
date of any such policy, a certificate evidencing a new or renewal policy shall
be delivered by Tenant to Landlord. Within fifteen (15) days after the premium
on any policy shall become due and payable, Landlord shall be furnished with
satisfactory evidence of its payment. To the extent obtainable, all policies
shall contain an agreement that notwithstanding any act or negligence of Tenant
which might otherwise result in forfeiture of such insurance, such policies
shall not be canceled except upon ten (10) days prior written notice to
Landlord, and that the coverage afforded thereby shall not be affected by the
performance of any work in or about the premises.

                      If Tenant  provides any insurance  required of Tenant,
by this lease in the form of a blanket policy, Tenant shall tarnish satisfactory
proof that such blanket policy compiles in all respects with the provisions of
this lease, and that the coverage thereunder is at least equal to the coverage
which would be provided under a separate policy covering only the premises.

                19.3 CHANGES IN STANDARD POLICIES. If the definition of
insurance industry policy language relating to "all risk" insurance or other
term changes, the insurance requirements hereunder shall be modified to conform
to the existing insurance industry language; however, the dollar amount of the
coverages required under this lease shall not be less than those existing at the
time of the effective beginning date of this lease.

        20. FIRE REGULATIONS -- TENANT RESPONSIBILITY. It shall be Tenant's sole
and exclusive responsibility to meet all fire regulations of any governmental
unit having jurisdiction over the premises to the extent such regulations affect
Tenants operations, at Tenant's sole expense.

        21. REPLACEMENT OF BUILDING -- CASUALTY DAMAGES. If the premises are
damaged or destroyed by fire or other cause at any time after the date of
commencement of this lease, Landlord shall proceed with due diligence to repair
or restore the same to the same condition as existed before such damage or
destruction, and as soon as possible thereafter will give possession to the
Tenant of the premises without diminution or change of location. Provided,
however, that in case of total destruction of the premises by fire, or in case
the premises are so badly damaged that in the opinion of the Landlord, it is not
feasible to repair or rebuild the same, then, Landlord shall have the right to
terminate this lease instead of rebuilding the improvements; provided, however,
that Landlord shall give Tenant written notice of Landlord's intention to
terminate, said notice to be served not later than thirty (30) days after the
occurrence of the damage to the property. In the event the premises are rendered
temporarily untenantable because of fire or other casualty, base monthly rent
shall abate on the untenantable area until the premises are restored to their
former condition, abatement to be based on the square feet of building floor
space in the untenantable area compared to the total square feet of building
floor space on the premises. Provided, however, that to the extent the damage or
destruction results from the negligence or other action of Tenant or its
employees, agents,


                                       13
<PAGE>

contractors, subcontractors, invitees, guests or licensees, Tenant shall pay for
the restoration or repair, to the extent the cost of same is not covered by
insurance.

of any event of default, Landlord shall have the option, without further notice
to Tenant or further demand for performance exercise any one or more of the
following remedies (and any other remedy available at law or in equity):

                        24.2.1 If Tenant has been late in payment of rent or
other sums due on four or more occasions during any period of one year.
Landlord, without terminating this lease, may (1) require that all future
payments be made by bank cashier's check, and/or (2) require an additional
security deposit in the amount of the then-current base rent for two months,
and/or (3) require that rent for each month be paid on or before the 15th day of
the preceding month. Such requirement shall be imposed by Landlord's written
notice delivered to Tenant. The additional security deposit shall be paid within
10 days after delivery of the notice. The Landlord may or may not exercise the
remedies provided in this Paragraph 24.2.1, in its sole discretion. The exercise
of the remedies provided in this Paragraph 24.2.1 shall not be required prior to
the exercise of any other available remedy.

                        24.2.2 Without obligation to seek a new tenant, to
institute suit against Tenant to collect each installment of rent or other sum
as it becomes due or to enforce any other obligation under this lease even
though the premises be left vacant.

                        24.2.3 As a matter of right, to procure the appointment
of a receiver for the premises by any court of competent jurisdiction upon ex
parte application and without notice, notice being hereby expressly waived. All
rents, issues and profits, income and revenue from the premises shall be applied
by such receiver to the payment of the rent, together with any other obligations
of the Tenant under this lease.

                        24.2.4 To re-enter and take possession of the premises
and all personal property therein and to remove Tenant and Tenant's agents and
employees therefrom, and either:

                                1) terminate this lease and sue Tenant for
damages for breach of the obligations of Tenant to Landlord under this lease; or

                                2) without terminating this lease, relet, assign
or sublet the premises and personal property, as the agent and for the account
of Tenant in the name of Landlord or otherwise, upon the terms and conditions
Landlord deems fit with the new Tenant for such period (which may be greater or
less than the period which would otherwise have constituted the balance of the
term of this lease) as Landlord may deem best, and collect any rent


                                       20
<PAGE>

due upon any such reletting. In this event, the rents received on any such,
reletting shall be applied first to the expenses of reletting and collecting,
including, without limitation, all repossession costs, reasonable attorneys'
fees, and real estate brokers' commissions, alteration costs and expenses of
preparing said premises for reletting, and thereafter toward payment of the
rental and of any other amounts payable by Tenant to Landlord. If the sum
realized shall not be sufficient to pay the rent and other charges due from
Tenant, then within five days after demand, Tenant will pay to Landlord any
deficiency as it accrues. Landlord may sue therefor as each deficiency shall
arise if Tenant shall fail to pay such deficiency within the time limited.

                24.3 TENANT TO SURRENDER PEACEABLY. In the event Landlord elects
to re-enter or take possession of the premises, Tenant shall quit and peaceably
surrender the premises to Landlord, and Landlord may enter upon and re-enter the
premises and possess and repossess itself thereof, by force, summary
proceedings, ejectment or otherwise, and may dispossess and remove Tenant and
may have, hold and enjoy the premises and the right to receive all rental income
of and from the same.

                24.4 NO TERMINATION BY RE-ENTRY. No re-entry or taking of
possession by Landlord shall be construed as an election on Landlord's part to
terminate or accept surrender of this lease unless Landlord's written notice of
such intention is delivered to Tenant.

                24.5 INJUNCTION. In the event of any breach by Tenant of any of
the agreements, terms, conditions or covenants contained in this lease,
Landlord, in addition to any and all other rights, shall be entitled to enjoin
such breach and shall have the right to invoke any right and remedy allowed at
law or in equity or by statute or otherwise for such breach as though re-entry,
summary proceedings, and other remedies were not provided for in this lease.

                24.6 REMEDIES LISTED ARE CUMULATIVE AND NON-EXCLUSIVE. The
enumeration of the foregoing remedies does not exclude any other remedy, but all
remedies are cumulative and shall be in addition to every other remedy now or
hereafter existing at law or in equity, including, but not limited to, the
remedies provided in Paragraph 25 concerning Landlord's security interest in
Tenant's personal property and Landlord's right to remove same.

                24.7 INTEREST ON SUMS PAST DUE. In addition to the late charge
which is elsewhere established, all rent and all other amounts due from Tenant
hereunder shall bear interest at the rate of eighteen (18%) percent per annum
compounded quarter-annually from their respective due dates until paid, provided
that this shall in no way limit, lessen or affect any claim for damages by
Landlord for any breach or default by Tenant.

                24.8 ATTORNEYS' FEES. Reasonable attorneys' fees, expert witness
fees, consulting fees and other expenses incurred by either party by reason of
the breach by either party in complying with any of the agreements, terms,
conditions or covenants of this lease shall constitute additional sums to be
paid to the prevailing party on demand.

                24.9 TIME TO CURE CERTAIN NON-MONETARY DEFAULTS. In the event of
any default other than failure to pay a sum of money, for which notice has been
given as provided herein, which because of its nature can be cured but not
within the period of grace heretofore allowed, then such default shall be deemed
remedied, if the correction thereof shall have been


                                       21
<PAGE>

commenced within said grace period or periods and shall, when commenced, be
diligently prosecuted to completion.

                24.10 LANDLORD DEFAULT. If Landlord is in default under any of
its obligations and the default continues for thirty (30) days after written
notice from Tenant (subject to extension pursuant to 24.9, Tenant may pursue all
remedies at law or in equity. Tenant may, but shall not be required to, correct
such default for the Landlord's account , and the expense shall be promptly paid
within ten (10) days by Landlord; however, in no event shall Tenant have the
right to rental abatement, offset of expenses against rental, or the right to
terminate this lease, subject to Tenant's legal or equitable remedies.

        Tenant may not offset any sum due or assertedly due from Landlord to
Tenant against any sum due from Tenant to Landlord.

        Tenant agrees that if Tenant obtains a judgment against Landlord arising
out of Landlord's obligations under this lease, such judgment may be satisfied
only by execution and sale of Landlord's interest in the premises leased hereby.
Tenant may not seek execution against other property of Landlord, nor pursue any
judgment, execution or other remedy against the partners or other owners of
Landlord or any of their property. Immediately upon receipt of Landlord's
written, request, Tenant will release any property (other than the premises
leased hereby) from the lien of any judgment obtained by Tenant against Landlord
arising out of Landlord's obligations under this lease.

        25. LANDLORD'S SECURITY INTEREST IN TENANT'S PERSONAL PROPERTY;
LANDLORD'S RIGHT TO REMOVE SAME. As security for its obligations under this
lease, Tenant grants to Landlord a security interest in all the personal
property and fixtures of Tenant now or subsequently located upon the premises
(the collateral). The security interest shall attach to the collateral at such
time (but not before) when Tenant fails to pay to Landlord any fixed sum of
money due to Landlord pursuant to this lease and only after Landlord has given
Tenant notice of the default and the default has remained uncured after the
period allowed for cure. Concurrently with signature hereof (or at such later
time when Landlord may demand same), Tenant will sign and deliver to landlord
financing statements properly evidencing the security interest, in customary
short form suitable for filing with the Secretary of State of the State of
Colorado and with the Boulder County Clerk and Recorder. The financing
statements shall not be filed prior to the date when the security interest
attaches to the collateral. In the event of default by Tenant, and after
attachment of the security interest to the collateral, Landlord may exercise all
rights and remedies available to the holders of security interests under the
Uniform Commercial Code as in effect in the State of Colorado.

        Landlord shall not be obligated to exercise any such remedy, however,
and at Landlord's sole election, Landlord may forego exercise of its rights
under the security agreement and proceed to remove, or have the appropriate
governmental agencies remove, all of Tenant's property from the premises and
leave same on any public street or landfill at Tenant's sole risk. The cost of
any such removal shall be paid by Tenant to Landlord upon demand.

        26. LEGAL PROCEEDINGS AGAINST TENANT BY THIRD PARTIES; TENANT TO PAY
LANDLORD'S FEES. In the event of any proceeding at law or in equity


                                       22
<PAGE>

wherein Landlord, without being in default as to its covenants under the terms
hereof, shall be made a party to any litigation by reason of Tenant's interest
in the premises, or, in the event Landlord shall be required to commence any
legal proceedings relating to the premises and Tenant's occupancy thereof and
Tenant's relation thereto, Landlord shall be allowed and Tenant shall be liable
for and shall pay all costs and expenses incurred by Landlord, including
reasonable attorneys' fees, expert witness fees and consultant's fees.

        27. INDEMNIFICATION BY TENANT AND BY LANDLORD. The Tenant shall
indemnify and save harmless Landlord of and from liability for damages or claims
against Landlord, including costs, attorneys' fees and expenses of Landlord in
defending against the same, on account of injuries to any person or property, if
the injuries are caused by the negligence or willful misconduct of Tenant, its
agents, servants or employees, or of any other person entering upon the premises
under express or implied invitation of Tenant or if such injuries are the result
of the violation by Tenant, its agents, servants, or employees, of laws,
ordinances, or of the terms of this lease.

        The Landlord shall indemnify and save harmless Tenant of and from
liability for damages or claims against Tenant, including costs, attorneys' fees
and expenses of Tenant in defending against the same, on account of injuries to
any person or property, if the injuries are caused by the negligence or willful
misconduct of Landlord, its agents, servants or employees, or of any other
person entering upon the premises primarily under express or implied invitation
of Landlord or where such injuries are the result of the violation by Landlord,
its agents, servants or employees, of laws, ordinances, or other governmental
regulations.

        28. ASSIGNMENT OR SUBLETTING. Tenant shall not assign, mortgage, or
encumber this lease, nor sublet or permit the premises or any part thereof to be
used by others, without the prior written consent of Landlord in each instance.

        In connection with an assignment, sublease or encumbrance Landlord may
require the submittal of detailed financial information about the prospective
subtenant or assignee, to be reviewed by Landlord, and may require a guarantee
of the obligations of the prospective subtenant or assignee, and may require
detailed financial information about the guarantor, to be reviewed by Landlord;
and there may be alterations to this lease and alterations to the building which
are necessary to consummate the transaction. The Landlord may require Tenant or
the prospective assignee or sub-tenant to pay for the alterations to the
building, and may require that Landlord perform same. In addition, Landlord may
charge a fee of two percent of base rent for the first five years of the lease,
due in full upon Landlord's consent, as payment to Landlord for such
investigations, lease alterations and similar matters. No two percent fee will
be charged in connection with an assignment or sublease to an assignee or
subtenant who is "affiliated" with Tenant. "Affiliated" means under common
voting control, directly or indirectly.

        A sale or transfer of control of a majority of the votes which may be
cast to elect Tenant's board of directors or other governing body shall be
deemed to be an assignment of this lease, requiring Landlord's consent if the
sale or transfer is essentially accomplished in a single transaction.


                                       23
<PAGE>

        If this lease is assigned, or if the premises or any part thereof is
sublet, or occupied by anyone other than Tenant, Landlord may, after default by
Tenant, collect rent from the assignee, subtenant, or occupant and apply the net
amount collected against all rent herein reserved. No such assignment,
subletting, occupancy, or collection shall be deemed a waiver of this covenant,
or the acceptance of the assignee, sub-tenant, or occupant as tenant; or a
release of Tenant from further performance by Tenant of the covenants in this
lease. The consent by Landlord to an assignment or subletting shall not be
construed to relieve Tenant (or any subsequent tenant) from obtaining the
consent in writing of Landlord to any further assignment or subletting.

        29. LANDLORD'S WARRANTY OF TITLE; QUIET ENJOYMENT. Landlord covenants it
has good right to lease the premises in the manner described herein and that
Tenant shall peaceably and quietly have, hold, occupy, and enjoy the premises
during the term of the lease; except as provided in Paragraph 32 concerning
subordination to mortgage lenders.

        30. ADDITIONAL DEVELOPMENT OF PROPERTY RIGHTS OF LANDLORD. Landlord does
reserve, during the term of this lease, the right to go upon and deal with the
premises or part thereof for the purpose of implementing a common development
plan for the project of which the premises are a part, and to make any other
changes and/or improvements as Landlord shall deem advisable in the exercise of
its sole discretion; provided, however, any such action by Landlord shall not
unreasonably interfere with the rights of Tenant hereunder.

        31. MENTAL ACQUISITION OF THE PREMISES. The parties agree that Landlord
shall have sole and exclusive authority to negotiate and settle all matters
pertaining to the acquisition of all or part of the premises by a governmental
agency by eminent domain or threat thereof (condemnation), and to convey all or
any part of the premises under threat of condemnation, and the lease shall
terminate as to any area so conveyed. It is agreed that any compensation for
land and/or buildings to be taken whether resulting from negotiation and
agreement or condemnation proceedings, shall be the exclusive property of
Landlord, and that there shall be no sharing whatsoever between Landlord and
Tenant of any such sum. Such taking of property shall not be considered as a
breach of this lease by Landlord, nor give rise to any claims in Tenant for
damages or compensation from Landlord. Tenant may separately claim and recover
from the condemning authority the value of any personal property owned by Tenant
which is taken, and any relocation expenses owed to Tenant by the condemning
authority. If the taken portion of the premises consists only of areas where no
building is constructed, and the land area of the premises is reduced by less
than ten percent, and the parking area available for use by Tenant is reduced by
less than five percent, and there is no material change in Tenant's access to
the premises, then there shall be no change in the terms of the lease. If no
building area is taken but the foregoing limits on parking area reductions are
exceeded, then Tenant may terminate the lease unless Landlord provides
sufficient reasonably adjacent parking area so that the total available parking
area is reduced by less than five percent. If any portion of the building or the
premises is taken, then Landlord, at its election, may replace the square
footage taken with space in the same building, or may provide land and building
area essentially the same as the premises in a reasonably adjacent location,
within 10 days after the conveyance or taking, under the same terms and
conditions as contained in this lease, and this lease shall be in full force and
effect as to the new premises. If Landlord does not so provide reasonable space,
then Tenant shall have two options. First, Tenant may terminate the lease by
written notice


                                       24
<PAGE>

delivered to Landlord within 60 days after the conveyance or taking. Second,
Tenant may retain the remaining portion of the premises, under all the terms and
conditions hereof, but the base rental shall be reduced in proportion to the
number of square feet of building floor space taken compared to the number of
square feet of building floor space on the premises prior to the taking.

        32. SUBORDINATION OF TAK LEASEHOLD TO MORTGAGES. This lease shall be,
subject and subordinate in priority at all times to the lien of any existing
and/or hereafter executed mortgages and host deeds encumbering the premises.
Although no instrument or act on the part of Tenant shall be necessary to
effectuate such subordination, Tenant will execute and deliver such further
instruments subordinating this lease to the lien of any such mortgages or trust
deeds as may be desired by the mortgagee or holder of such trust deeds. Tenant
hereby appoints Landlord as his attorney in fact, irrevocably, to execute and
deliver any such instrument for Tenant. Tenant further agrees at any time and
from time to lime upon not less than ten (10) days prior written request by
Landlord, to execute, acknowledge, and deliver to Landlord an estoppel affidavit
in form acceptable to Landlord and the holder of any existing or contemplated
mortgage or deed of trust encumbering the premises. Tenant's failure to deliver
such statement within such time shall be conclusive upon Tenant (1) that this
lease is in full force and affect, without modification except as maybe
represented by Landlord; (2) that there are no uncured defaults in Landlord's
performance; and (3) that not more than one (1) month's rent has been paid in
advance. Further, upon request, Tenant shall supply to Landlord a corporate
resolution certifying that the party signing this statement on behalf of Tenant
is properly authorized to do so, if Tenant is a corporation. Tenant agrees to
provide Landlord within ten business days of Landlord's request, Tenant's most
recently completed financial statements and such other financial information as
reasonably requested by Landlord in order to verify Tenant's financial condition
to satisfy requirements of Landlord's existing or contemplated lender or
mortgagee.

        Tenant agrees with lender and Landlord that if there is a foreclosure of
any such mortgage or deed of trust and pursuant to such foreclosure, the Public
Trustee or other appropriate officer executes and delivers a deed conveying the
premises to the lender or its designee, or in the event Landlord conveys the
premises to the lender or its designee in lieu of foreclosure, Tenant will
attorn to such grantee of the premises, rather than to Landlord, to perform all
of Tenant's obligations under the lease, and Tenant shall have no right to
terminate the lease by reason of the foreclosure or deed given in lieu thereof.

        Landlord will endeavor to include in the terms of any mortgage or deed
of trust an the premises a provision that if Tenant is not in default under the
terms of this lease and Tenant is then in possession of the premises, Tenant's
rights of quiet enjoyment arising out of the lease shall not be affected or
disturbed by lender in the event of a default by Landlord and any sale of the
premises through foreclosure of any deed of trust or otherwise.

        33. TENANT'S GUARANTEE AND FINANCIAL STATEMENTS. This lease, and
Tenant's performance hereunder, shall be guaranteed by Quantum Consulting
Associates, by the execution of the Guarantee Agreement attached hereto. A
current financial statement of Tenant and of any parties so guaranteeing this
lease shall be provided to Landlord upon execution hereof and annually
thereafter if so requested by Landlord.

        34. MEMORANDUM OF LEASE -- RECORDING. This lease shall not be recorded
in the office of the County Clerk and Recorder of Boulder County, except by
Landlord as a financing statement. In order to effect public recordation, the
parties hereto may, at the time this lease is executed, agree to execute a
Memorandum of lease incorporating therein by reference the terms of this lease,
but deleting therefrom any expressed statement or mention of the amount of rent
herein reserved, which instrument may be recorded by either party in the office
of the Clerk and Recorder of Boulder County.

        35. NO WAIVER OF BREACH; ACCEPTANCE OF PARTIAL PAYMENTS OF RENT. No
assent, or waiver expressed or implied, or failure to enforce, as to any breach
of any one or more of the covenants or agreements herein shall be deemed or
taken to be a waiver of any succeeding or additional breach.

        Payment by Tenant or receipt by Landlord of an amount less than the rent
or other payment provided for herein shall not be deemed to be other than a
payment on account of the earliest rent then due, nor shall any endorsement or
statement on any check or any letter accompanying any check or payment of rent
be deemed an accord and satisfaction, and Landlord may accept such check or
other payment without prejudice to Landlord's right to recover the balance of
all rent then due, and/or to pursue any or all other remedies provided for in
this lease, in law, and/or in equity including, but not limited to, eviction of
Tenant. Specifically, but not as a limitation, acceptance of a partial payment
of rent shall not be a wavier of any default by Tenant.

        36. CONTROLLING LAW. The lease, and all terms hereunder shall be
governed by the laws of the State of Colorado, exclusive of its conflicts of
laws rules.

        37. INUREMENTS. The covenants and agreements herein contained shall bind

                               INDEMNITY AGREEMENT

            THIS INDEMNITY AGREEMENT dated as of ______________ ____, 2000 (the
"Agreement"), is entered into by and between Vastera, Inc., a Delaware
corporation (the "Company"), and _____________________ ("Indemnitee").

                                    RECITALS

          A. The Company is aware that competent and experienced persons are
increasingly reluctant to serve as directors, officers or agents of corporations
unless they are protected by comprehensive liability insurance or
indemnification, due to increased exposure to litigation costs and risks
resulting from their service to such corporations, and due to the fact that the
exposure frequently bears no reasonable relationship to the compensation of such
directors, officers and other agents.

          B. The statutes and judicial decisions regarding the duties of
directors and officers are often difficult to apply, ambiguous, or conflicting,
and therefore fail to provide such directors, officers and agents with adequate,
reliable knowledge of legal risks to which they are exposed or information
regarding the proper course of action to take.

          C. Plaintiffs often seek damages in such large amounts and the costs
of litigation may be so enormous (regardless of whether the case is
meritorious), that the defense or settlement of such litigation is often beyond
the personal resources of directors, officers and other agents.

          D. The Company believes that it is unfair for its directors, officers
and agents and the directors, officers and agents of its subsidiaries to assume
the risk of significant judgments and other expenses that may be awarded in
cases in which the director, officer or agent received no personal profit and in
cases where the director, officer or agent was not culpable.

          E. The Company recognizes that the issues in controversy in litigation
against a director, officer or agent of a corporation such as the Company or its
subsidiaries are often related to the knowledge, motives and intent of such
director, officer or agent, that he is usually the only witness with knowledge
of the essential facts and exculpating circumstances regarding such matters, and
that the long period of time which usually elapses before the trial or other
disposition of such litigation often extends beyond the time that the director,
officer or agent can reasonably recall such matters; and may extend beyond the
normal time for retirement for such director, officer or agent with the result
that he, after retirement or in the event of his death, his spouse, heirs,
executors or administrators, may be faced with limited ability and undue
hardship in maintaining an adequate defense, which may discourage such a
director, officer or agent from serving in that position.

<PAGE>

          F. Based upon their experience as business managers, the Board of
Directors of the Company (the "Board") has concluded that, to retain and attract
talented and experienced individuals to serve as directors, officers and agents
of the Company and its subsidiaries and to encourage such individuals to take
the business risks necessary for the success of the Company and its
subsidiaries, it is necessary for the Company to contractually indemnify its
directors, officers and agents and the directors, officers and agents of its
subsidiaries, and to assume for itself maximum liability for expenses and
damages in connection with claims against such directors, officers and agents in
connection with their service to the Company and its subsidiaries, and has
further concluded that the failure to provide such contractual indemnification
could result in great harm to the Company and its subsidiaries and the Company's
stockholders.

          G. Section 145 of the General Corporation Law of Delaware, under which
the Company is organized ("Section 145"), empowers the Company to indemnify its
directors, officers, employees and agents by agreement and to indemnify persons
who serve, at the request of the Company, as the directors, officers, employees
or agents of other corporations or enterprises, and expressly provides that the
indemnification provided by Section 145 is not exclusive.

          H. The Company desires and has requested the Indemnitee to serve or
continue to serve as a director, officer or agent of the Company and/or one or
more subsidiaries of the Company free from undue concern for claims for damages
arising out of or related to such services to the Company and/or one or more
subsidiaries of the Company.

          I. Indemnitee is willing to serve, or to continue to serve, the
Company and/or one or more subsidiaries of the Company, provided that he is
furnished the indemnity provided for herein.

                                    AGREEMENT

          NOW, THEREFORE, the parties hereto, intending to be legally bound,
hereby agree as follows:

     1. DEFINITIONS.

          (a) AGENT. For the purposes of this Agreement, "agent" of the Company
means any person who is or was a director, officer, employee or other agent of
the Company or a subsidiary of the Company; or is or was serving at the request
of, for the convenience of, or to represent the interests of the Company or a
subsidiary of the Company as a director, officer, employee or agent of another
foreign or domestic corporation, partnership, joint venture, trust or other
enterprise; or was a director, officer, employee or agent of a foreign or
domestic corporation which was a predecessor corporation of the Company or a
subsidiary of the Company, or was a director, officer, employee or agent of
another enterprise at the request of, for the convenience of, or to represent
the interests of such predecessor corporation.

          (b) EXPENSES. For purposes of this Agreement, "expenses" include all
out-of-pocket costs of any type or nature whatsoever (including, without
limitation, all attorneys' fees and related disbursements), actually and
reasonably incurred by the Indemnitee in connection


                                       2
<PAGE>

with either the investigation, defense or appeal of a proceeding or establishing
or enforcing a right to indemnification under this Agreement or Section 145 or
otherwise; provided, however, that "expenses" shall not include any judgments,
fines, ERISA excise taxes or penalties, or amounts paid in settlement of a
proceeding.

          (c) PROCEEDING. For the purposes of this Agreement, "proceeding" means
any threatened, pending, or completed action, suit or other proceeding, whether
civil, criminal, administrative, or investigative.

          (d) SUBSIDIARY. For purposes of this Agreement, "subsidiary" means any
corporation of which more than 50% of the outstanding voting securities is owned
directly or indirectly by the Company, by the Company and one or more other
subsidiaries, or by one or more other subsidiaries.

     2. AGREEMENT TO SERVE. The Indemnitee agrees to serve and/or continue to
serve as agent of the Company, at its will (or under separate agreement, if such
agreement exists), in the capacity Indemnitee currently serves as an agent of
the Company, so long as he is duly appointed or elected and qualified in
accordance with the applicable provisions of the Bylaws of the Company or any
subsidiary of the Company or until such time as he tenders his resignation in
writing; provided, however, that nothing contained in this Agreement is intended
to create any right to continued employment by Indemnitee.

     3. LIABILITY INSURANCE.

          (a) MAINTENANCE OF D&O INSURANCE. At such time as the Board of
Directors deems it appropriate to obtain such insurance but not before such
time, the Company hereby covenants and agrees that, so long as the Indemnitee
shall continue to serve as an agent of the Company and thereafter so long as the
Indemnitee shall be subject to any possible proceeding by reason of the fact
that the Indemnitee was an agent of the Company, the Company, subject to Section
3(c), shall promptly obtain and maintain in full force and effect directors' and
officers' liability insurance ("D&O Insurance") in reasonable amounts from
established and reputable insurers.

          (b) RIGHTS AND BENEFITS. In all policies of D&O Insurance, the
Indemnitee shall be named as an insured in such a manner as to provide the
Indemnitee the same rights and benefits as are accorded to the most favorably
insured of the Company's directors, if the Indemnitee is a director; or of the
Company's officers, if the Indemnitee is not a director of the Company but is an
officer; or of the Company's key employees, if the Indemnitee is not a director
or officer but is a key employee.

          (c) LIMITATION ON REQUIRED MAINTENANCE OF D&O INSURANCE.
Notwithstanding the foregoing, the Company shall have no obligation to obtain or
maintain D&O Insurance if the Company determines in good faith that such
insurance is not reasonably available, the premium costs for such insurance are
disproportionate to the amount of coverage provided, the coverage provided by
such insurance is limited by exclusions so as to provide an insufficient
benefit, or the Indemnitee is covered by similar insurance maintained by a
subsidiary of the Company.


                                       3
<PAGE>

     4. MANDATORY INDEMNIFICATION. Subject to Section 9 below, the Company shall
indemnify the Indemnitee as follows:

          (a) SUCCESSFUL DEFENSE. To the extent the Indemnitee has been
successful on the merits or otherwise in defense of any proceeding (including,
without limitation, an action by or in the right of the Company) to which the
Indemnitee was a party by reason of the fact that he is or was an Agent of the
Company at any time, against all expenses of any type whatsoever actually and
reasonably incurred by him in connection with the investigation, defense or
appeal of such proceeding.

          (b) THIRD PARTY ACTIONS. If the Indemnitee is a person who was or is a
party or is threatened to be made a party to any proceeding (other than an
action by or in the right of the Company) by reason of the fact that he is or
was an agent of the Company, or by reason of anything done or not done by him in
any such capacity, the Company shall indemnify the Indemnitee against any and
all expenses and liabilities of any type whatsoever (including, but not limited
to, judgments, fines, ERISA excise taxes and penalties, and amounts paid in
settlement) actually and reasonably incurred by him in connection with the
investigation, defense, settlement or appeal of such proceeding, provided the
Indemnitee acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the Company and its stockholders, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful.

          (c) DERIVATIVE ACTIONS. If the Indemnitee is a person who was or is a
party or is threatened to be made a party to any proceeding by or in the right
of the Company by reason of the fact that he is or was an agent of the Company,
or by reason of anything done or not done by him in any such capacity, the
Company shall indemnify the Indemnitee against all expenses actually and
reasonably incurred by him in connection with the investigation, defense,
settlement, or appeal of such proceeding, provided the Indemnitee acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Company and its stockholders; except that no indemnification
under this subsection 4(c) shall be made in respect to any claim, issue or
matter as to which such person shall have been finally adjudged to be liable to
the Company by a court of competent jurisdiction unless and only to the extent
that the court in which such proceeding was brought shall determine upon
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such amounts which the court shall deem proper.

          (d) ACTIONS WHERE INDEMNITEE IS DECEASED. If the Indemnitee is a
person who was or is a party or is threatened to be made a party to any
proceeding by reason of the fact that he is or was an agent of the Company, or
by reason of anything done or not done by him in any such capacity, and if prior
to, during the pendency of after completion of such proceeding Indemnitee
becomes deceased, the Company shall indemnify the Indemnitee's heirs, executors
and administrators against any and all expenses and liabilities of any type
whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes
and penalties, and amounts paid in settlement) actually and reasonably incurred
to the extent Indemnitee would have been entitled to indemnification pursuant to
Sections 4(a), 4(b), or 4(c) above were Indemnitee still alive.


                                       4
<PAGE>

          (e) Notwithstanding the foregoing, the Company shall not be obligated
to indemnify the Indemnitee for expenses or liabilities of any type whatsoever
(including, but not limited to, judgments, fines, ERISA excise taxes and
penalties, and amounts paid in settlement) for which payment is actually made to
or on behalf of Indemnitee under a valid and collectible insurance policy of D&O
Insurance, or under a valid and enforceable indemnity clause, by-law or
agreement.

     5. PARTIAL INDEMNIFICATION. If the Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of any expenses or liabilities of any type whatsoever (including, but
not limited to, judgments, fines, ERISA excise taxes and penalties, and amounts
paid in settlement) incurred by him in the investigation, defense, settlement or
appeal of a proceeding, but not entitled, however, to indemnification for all of
the total amount hereof, the Company shall nevertheless indemnify the Indemnitee
for such total amount except as to the portion hereof to which the Indemnitee is
not entitled.

     6. MANDATORY ADVANCEMENT OF EXPENSES. Subject to Section 8(a) below, the
Company shall advance all expenses incurred by the Indemnitee in connection with
the investigation, defense, settlement or appeal of any proceeding to which the
Indemnitee is a party or is threatened to be made a party by reason of the fact
that the Indemnitee is or was an agent of the Company. Indemnitee hereby
undertakes to repay such amounts advanced only if, and to the extent that, it
shall be determined ultimately that the Indemnitee is not entitled to be
indemnified by the Company as authorized hereby. The advances to be made
hereunder shall be paid by the Company to the Indemnitee within twenty (20) days
following delivery of a written request therefor by the Indemnitee to the
Company.

     7. NOTICE AND OTHER INDEMNIFICATION PROCEDURES.

          (a) Promptly after receipt by the Indemnitee of notice of the
commencement of or the threat of commencement of any proceeding, the Indemnitee
shall, if the Indemnitee believes that indemnification with respect thereto may
be sought from the Company under this Agreement, notify the Company of the
commencement or threat of commencement thereof.

          (b) If, at the time of the receipt of a notice of the commencement of
a proceeding pursuant to Section 7(a) hereof, the Company has D&O Insurance in
effect, the Company shall give prompt notice of the commencement of such
proceeding to the insurers in accordance with the procedures set forth in the
respective policies. The Company shall thereafter take all necessary or
desirable action to cause such insurers to pay, on behalf of the Indemnitee, all
amounts payable as a result of such proceeding in accordance with the terms of
such policies.

          (c) In the event the Company shall be obligated to pay the expenses of
any proceeding against the Indemnitee, the Company, if appropriate, shall be
entitled to assume the defense of such proceeding, with counsel approved by the
Indemnitee, upon the delivery to the Indemnitee of written notice of its
election so to do. After delivery of such notice, approval of such counsel by
the Indemnitee and the retention of such counsel by the Company, the Company
will not be liable to the Indemnitee under this Agreement for any fees of
counsel subsequently incurred by the Indemnitee with respect to the same
proceeding, provided that (i) the Indemnitee


                                       5
<PAGE>

shall have the right to employ his counsel in any such proceeding at the
Indemnitee's expense; and (ii) if (A) the employment of counsel by the
Indemnitee has been previously authorized by the Company, (B) the Indemnitee
shall have reasonably concluded that there may be a conflict of interest between
the Company and the Indemnitee in the conduct of any such defense, or (C) the
Company shall not, in fact, have employed counsel to assume the defense of such
proceeding, then the fees and expenses of Indemnitee's counsel shall be at the
expense of the Company.

     8. EXCEPTIONS. Any other provision herein to the contrary notwithstanding,
the Company shall not be obligated pursuant to the terms of this Agreement:

          (a) CLAIMS INITIATED BY INDEMNITEE. To indemnify or advance expenses
to the Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by the Indemnitee and not by way of defense, unless (i) such
indemnification is expressly required to be made by law, (ii) the proceeding was
authorized by the Board, (iii) such indemnification is provided by the Company,
in its sole discretion, pursuant to the powers vested in the Company under the
General Corporation Law of Delaware or (iv) the proceeding is brought to
establish or enforce a right to indemnification under this Agreement or any
other statute or law or otherwise as required under Section 145.

          (b) LACK OF GOOD FAITH. To indemnify the Indemnitee for any expenses
incurred by the Indemnitee with respect to any proceeding instituted by the
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous; or

          (c) UNAUTHORIZED SETTLEMENTS. To indemnify the Indemnitee under this
Agreement for any amounts paid in settlement of a proceeding unless the Company
consents to such settlement, which consent shall not be unreasonably withheld.

     9. NON-EXCLUSIVITY. The provisions for indemnification and advancement of
expenses set forth in this Agreement shall not be deemed exclusive of any other
rights which the Indemnitee may have under any provision of law, the Company's
Certificate of Incorporation or Bylaws, the vote of the Company's stockholders
or disinterested directors, other agreements, or otherwise, both as to action in
his official capacity and to action in another capacity while occupying his
position as an agent of the Company, and the Indemnitee's rights hereunder shall
continue after the Indemnitee has ceased acting as an agent of the Company and
shall inure to the benefit of the heirs, executors and administrators of the
Indemnitee.

     10. ENFORCEMENT. Any right to indemnification or advances granted by this
Agreement to Indemnitee shall be enforceable by or on behalf of Indemnitee in
any court of competent jurisdiction if (i) the claim for indemnification or
advances is denied, in whole or in part, or (ii) no disposition of such claim is
made within ninety (90) days of request therefor. Indemnitee, in such
enforcement action, if successful in whole or in part, shall be entitled to be
paid also the expense of prosecuting his claim. It shall be a defense to any
action for which a claim for indemnification is made under this Agreement (other
than an action brought to enforce a claim for expenses pursuant to Section 6
hereof, provided that the required undertaking has been tendered to the Company)
that Indemnitee is not entitled to indemnification because of the


                                       6
<PAGE>

limitations set forth in Sections 4 and 8 hereof. Neither the failure of the
Company (including its Board of Directors or its stockholders) to have made a
determination prior to the commencement of such enforcement action that
indemnification of Indemnitee is proper in the circumstances, nor an actual
determination by the Company (including its Board of Directors or its
stockholders) that such indemnification is improper, shall be a defense to the
action or create a presumption that Indemnitee is not entitled to
indemnification under this Agreement or otherwise.

11. SUBROGATION. In the event of payment under this Agreement, the Company shall
be subrogated to the extent of such payment to all of the rights of recovery of
Indemnitee, who shall execute all documents required and shall do all acts that
may be necessary to secure such rights and to enable the Company effectively to
bring suit to enforce such rights.

12.         SURVIVAL OF RIGHTS.

          (a) All agreements and obligations of the Company contained herein
shall continue during the period Indemnitee is an agent of the Company and shall
continue thereafter so long as Indemnitee shall be subject to any possible claim
or threatened, pending or completed action, suit or proceeding, whether civil,
criminal, arbitrational, administrative or investigative, by reason of the fact
that Indemnitee was serving in the capacity referred to herein.

          (b) The Company shall require any successor(s) to the Company (whether
direct or indirect, by purchase, merger, consolidation or otherwise) or to all
or substantially all of the business or assets of the Company, expressly to
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform if no such succession had
taken place.

     13. INTERPRETATION OF AGREEMENT. It is understood that the parties hereto
intend this Agreement to be interpreted and enforced so as to provide
indemnification to the Indemnitee to the fullest extent permitted by law
including those circumstances in which indemnification would otherwise be
discretionary.

     14. SEVERABILITY. If any provision or provisions of this Agreement shall be
held to be invalid, illegal or unenforceable for any reason whatsoever, (i) the
validity, legality and enforceability of the remaining provisions of the
Agreement (including without limitation, all portions of any paragraphs of this
Agreement containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby, and (ii) to the fullest extent
possible, the provisions of this Agreement (including, without limitation, all
portions of any paragraph of this Agreement containing any such provision held
to be invalid, illegal or unenforceable, that are not themselves invalid,
illegal or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable and to give
effect to Section 13 hereof.

     15. MODIFICATION AND WAIVER. No supplement, modification or amendment of
this Agreement shall be binding unless executed in writing by both of the
parties hereto. No waiver of any of the provisions of this Agreement shall be
deemed or shall constitute a waiver of any


                                       7
<PAGE>

other provisions hereof (whether or not similar) nor shall such waiver
constitute a continuing waiver.

     16. NOTICE. All notices, requests, demands and other communications under
this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and receipted for by the party addressee, on the date of
delivery, or (ii) if mailed by certified or registered mail with postage
prepaid, on the third business day after the mailing date. Addresses for notice

Directors are ineligible to receive an award of options under the Plan. Except
where the context otherwise requires, the term "Company" shall include the
parent and all subsidiaries of the Company as defined in Section 424(e) and
424(f) of the Internal revenue Code of 1986, as amended (the "Code").

                     2. TYPE OF OPTIONS AND ADMINISTRATION.

         (a)  TYPES OF OPTIONS. Options granted pursuant to the Plan may be
              either incentive stock options ("Incentive Stock Options") meeting
              the requirements of Section 422 of the Code or non-statutory
              options, which are not intended to meet the requirements of
              Section 422 of the Code.

         (b)  ADMINISTRATION. The Plan shall be administered by a committee (the
              "Committee") appointed by the Board of Directors. The Committee
              hall consist of not less than two (2) members. The Committee
              shall, in its sole discretion, grant options of purchase shares of
              the Company's common stock (the "Common Stock") as provided in the
              Plan. The Board of Directors shall have authority, subject to the
              express provisions of the Plan: (I) to amend the Plan and (II) to
              prescribe, amend and rescind rules and regulations relating to the
              Plan. The Committee shall have authority, subject the express
              provisions of the Plan: (I) to amend and construe the respective
              option agreements executed pursuant to the Plan, including the
              authority to amend such option agreements executed pursuant of the
              Plan, including the authority to amend such option agreement
              executed prior to the adoption of the Plan; (II) to establish and
              determine all of the terms and provisions of the respective option
              agreements, which need not be identical; and (III) to make any
              other determination in the judgement of the Committee necessary or
              desirable for the administration of he Plan. The Committee may
              correct any defect or supply any omission or reconcile any
              inconsistency in the Plan or in any option agreement in the manner
              and to the extant it shall deem expedient to carry the Plan into
              effect and it shall be the sole and final judge of such
              expediency. No member of the Committee or Director of the company
              shall be liable for any action or determination made in good
              faith.

                                3. ELIGIBILITY.

         Options shall be granted only to persons who are, at the time of grant,
employees (including officers and directors who are employees) or consultants of
the Company. A person who has been granted an option may, if he or she is
otherwise eligible, be granted an additional option or options if the Committee
shall so determine.

Plan is 400,000 shares. Such shares may be authorized and unissued shares or may
be shares issued and thereafter acquired by the Company. If an option granted
under the Plan shall expire or terminate for any reason without having been
exercised in full, the unpurchased shares subject to such option shall again be

are intended to be Incentive Stock Options (to the maximum extent possible) or
non-statutory options.

              the purchase price shall not be less than 100% of the "fair market
              value" in the case of options described in paragraph (b) of
              Section 11. For purposes of this section 6 the "fair market value"
              of the stock shall be either: (A) as determined by the committee,
              or (B) in the event the Company's Common Stock is publicly traded,
              the price of the Common Stock on the date of grant of such option

              upon which the Company's stock is listed.

         (b)  PAYMENT OF PURCHASE PRICE. Options granted under the Plan may
              provide for the payment of the purchase price by any method that

of Section 11) and, in the case of non-statutory options, in no event after the
expiration of ten (10) years and one day from the day on which the option is
granted, and in either case, shall be subject to earlier termination as provided
in the relevant option agreement.

                            8. EXERCISE OF OPTIONS.

         Each option granted under the Plan shall be exercisable either in full
or in installments at one such time or times, during such period and subject to
such conditions as shall be determined by the committee and set forth in the
agreement evidencing such option, subject to the provisions of Section 7 above.

transferable by the person to whom it is granted, either voluntarily or by
operation of law, except by will or the laws of descent and distribution. During
the life of the optionee, an Incentive Stock Option shall be exercisable only by
such person. A no-statutory stock option may be assigned or transferred in whole
or in part only if so provided in the relevant agreement or if permitted by the
Committee.

option agreement so provides.

         (a)  an Incentive Stock Option may be exercised within the period
              ending on the earlier of the tenth anniversary of the date of
              grant or three (3) months after the optionee ceases to be employed
              by or in the service of the Company (or within such lesser period
              as may be specified in the applicable option agreement);

         (b)  if the optionee dies while employed by or in the service of the
              Company, the option may be exercised by the person to whom it is
              transferred by will or the laws of descent and distribution within
              the period of one (1) year after the date the optionee ceases to
              be employed by or in the service of the Company, the option may be
              exercised within the period of one (1) year after the date of
              death (or within such lesser period as may be specified in the
              applicable option agreement); and

         (c)  if the optionee becomes disabled (within the meaning of Section
              22(e)(3) of the Code or any successor provision thereto) while
              employed by or in the service of the Company, the option may be
              exercised within the period of one (1) calendar year after the
              date the optionee ceases to be employed by or in the service of
              the Company because of such disability (or within such lesser
              period as may be specified in the applicable option agreement);
              provided, however, that in no event may any option be exercised
              after the expiration date of the option.

                          11. INCENTIVE STOCK OPTIONS.

         (a)  Dollar Limitation. Incentive Stock Option granted to any employee
              under the Plan (and any other incentive stock option plans of the
              Company) shall not, in the aggregate, become exercisable for the
              first time in any one (1) calendar year for shares of Common Stock
              with an aggregate fair market value (determined as one of the
              respective date or dates of grant) of more than $100,000. In the
              event Section 422 (d) of the Code is amended to alter the
              limitation set forth in this paragraph (a), the limitation of this
              paragraph (a) shall be automatically adjusted accordingly.

         (b)  10% SHAREHOLDER. If any employee to whom an Incentive Stock Option
              is to be granted under the Plan is , at the time of the grant such

              total combined voting power of all classes of stock of the Company
              (after taking into account the attribution of stock ownership
              rules of section

              424(d) of the Code), then the following special provisions shall
              be applicable to the Incentive Stock Option granted to such
              individual:

              1.   The purchase price per share of the Common Stock subject to
                   such Incentive Stock Option shall not be less than 110% of
                   the fair market value of one (1) share of Common Stock at the
                   time of grant; and

              2.   The option exercise period shall not exceed five (5) years
                   from the date of grant.

                           12. ADDITIONAL PROVISIONS.

         (a)  ADDITIONAL OPTION PROVISIONS. The Committee may, in its sole
              discretion include additional provisions in any option granted

              cash bonuses, make or arrange for loans or transfer other property
              to optionees upon exercise of options, or such other provisions as
              shall be determined by the Committee; PROVIDED THAT such
              additional provisions shall not be inconsistent with any other
              term or condition of the Plan and such additional provisions shall
              not cause any Incentive Stock Option within the meaning of Section
              422 of the Code.

         (b)  ACCELERATION AND WAIVER. The Committee may, in its sole discretion
              accelerate the date or dates on which all or any particular option
              or options granted under the Plan may be exercised or waive any
              conditions with respect to any option.

                           13. GENERAL RESTRICTIONS.

         (a)  INVESTMENT RESTRICTIONS. The Company may require any person to
              whom an option is granted, as a condition of exercising such

              any governmental or regulatory body, is necessary as a condition
              of, or in connection with, the issuance or purchase of shares
              thereunder, such option may not be exercised, in whole or in part,
              unless such listing, registration, qualification, consent or
              approval shall have been effected or obtained on conditions
              acceptable to the Committee. Nothing herein shall be deemed to
              require the Company to apply for or to obtain such listing,
              registration or qualifications.

                          14. RIGHTS AS A SHAREHOLDER.

              Stock or other securities, the outstanding shares of Common Stock
              are increased or decreased, or are exchanged for a different
              number or kind of shares or other securities, or additional shares
              or new or different shares or other securities, an appropriate and
              proportionate adjustment may be made in (I) the maximum number and
              kind of shares reserved for issuance under the Plan, (ii) the
              number and kind of shares or other securities subject to then
              outstanding options under the Plan, and (iii) the price for each
              share subject to any then outstanding options under the Plan,
              without changing the aggregate purchase price as to which such
              options remain exercisable.

         (b)  COMMITTEE AUTHORITY TO MAKE ADJUSTMENTS. Adjustments under this
              Section 15 will be made by the Committee, whose determination as

              Common Stock by single person, entity or group of persons or
              entities acting in concert, or in the event of a sale or transfer
              of all or substantially all of the assets of the Company, or in
              the event of a reorganization or liquidation of the Company, then

              event or transaction, and such options may be exercised by the
              option holder in accordance with the provisions set forth in the
              Plan.

         (b)  SUBSTITUTE OPTIONS. The Committee may grant options under the Plan
              in substitution for options held by employees of another
              corporation who become employees of the Company, or a subsidiary
              of the Company, as a result of a merger or consolidation of the
              employing corporation with the Company or a subsidiary of the
              Company, or as a result of the acquisition by the Company, or one
              of its subsidiaries, of property or stock of the employing
              corporation. Substitute options may be granted on such terms and
              conditions as the Committee considers appropriate in the

              securities of the Company representing 50% or more of the combined
              voting power of the Company's then outstanding securities;

         (b)  during any period of two consecutive years ending during the term
              of the Plan (not including any period prior to the adoption of the
              Plan), individuals who at the beginning of such period constitute
              the Board of Directors of the Company, and any new Director (other

              beginning of the period or whose election or whose nomination for
              election was previously so approved (collectively, the
              "Disinterested Directors"), cease for any reason to constitute a
              majority of the Board of Directors.

         (c)  the stockholders of the Company approve a merger or consolidation
              of the Company with any other corporation, other than (A) a merger
              or consolidation which would result in the voting securities of
              the Company outstanding immediately prior thereto continuing to
              represent (either by remaining outstanding or by being converted
              into voting securities of the surviving entity) more than 50% of
              the combined voting power of the voting securities of the Company
              or such surviving entity outstanding immediately after such a
              merger or consolidation or (B) a merger or consolidation effected
              to implement a recapitalization of the Company (or similar
              transaction) in which no "person" (as herein defined) acquires
              more than 50% of the combined voting power of the Company's then

share that may be lower or higher than the purchase price per share of the
canceled options and having such other terms as the committee may approve.

                  22. EFFECTIVE DATE AND DURATION OF THE PLAN.

         (a)  EFFECTIVE DATE. The Plan shall become effective when adopted by
              the Board of Directors, but no Incentive Stock Option granted
              under the Plan shall become exercisable unless and until the Plan
              shall have been approved by the company's stockholders. If such
              stockholder approval is not obtained within twelve (12) months
              after the date of the Board's adoption of he Plan, any Incentive
              Stock Options previously granted under the Plan shall terminate
              and no further Incentive Stock Options shall be granted.
              Amendments to the Plan shall become effective when adopted by the
              Board of Directors; amendments requiring stockholder approval
              under Section 422 of the Code shall, to the extent determined by
              the Board of Directors, become effective when adopted by the Board
              of Directors, but no Incentive Stock Option issued after the date
              of such amendment shall become exercisable (to the extent that
              such amendment to the Plan was required to enable the Company to
              grant such Incentive Stock Option to a particular optionee) unless
              and until such amendment shall have been approved by the Company's
              stockholders. If such stockholder approval is not obtained within
              twelve (12) months of the Board of Director's adoption such
              amendment shall terminate to the extent that such amendment to the
              Plan was required to enable the Company to grant such option to a
              particular optionee. Subject to this limitation, options may be
              granted under the Plan at any time after the effective date and
              before the date fixed for termination of the Plan.

         (b)  TERMINATION. The Plan shall terminate upon the earlier of (I) the
              close of business on the day next preceding the tenth anniversary
              of the date of its adoption by the Board of Directors, or (ii) the
              date on which all shares available for issuance under the Plan
              shall have been issued pursuant to the exercise or cancellation of
              options granted under the Plan. If the date of termination is
              determined under (I) above, then options outstanding on such date
              shall continue to have force and effect in accordance with the
              provisions of the instruments evidencing such options.

<PAGE>

provided below, the right to exercise this Option shall terminate three (3)
months after such cessation (but in no event after the Expiration Date),

Option by bequest or inheritance or otherwise by reason of the death of the
Optionee.

the Company, which determination shall be conclusive.

purchased upon exercise of this Option shall be made by delivery to the Company
of cash or a check to the order of the Company in an amount equal to the
purchase price of such shares, or, with the separate consent of the Company, by
delivery to the Company of shares of Common Stock of the Company, then owned by
the Optionee having a fair market value equal in amount to the purchase price of
such shares, or by any combination of such methods of payment.

Stock of the Company, the certificate or certificates representing the shares of
Common Stock of the Company to be delivered shall be duly executed in blank by
the Optionee or shall be accompanied by a stock power duly executed in blank
suitable for purposes of transferring such shares to the Company. Fractional
shares of Common Stock of the Company will not be accepted ion payment of

to the contrary contained in the foregoing subsections 4(a) and 4(c), no shares
of Common Stock of the Company may be tendered in payment of the purchase price
of shares purchased upon exercise of this Option if the shares to be so tendered
were acquired within twelve (12) months before the date of such tender, through
the exercise of an option granted under the Plan or any other stock option or
restricted stock plan of the Company.

         5. DELIVERY OF SHARES; COMPLIANCE WITH SECURITIES LAW, ETC.

<PAGE>

                  (a) GENERAL. The Company shall, upon receipt of the Optionee's
payment of the option price for the number of shares purchased and paid for,
make prompt delivery of such shares to the Optionee, provided that if any law or
regulation requires the Company to take any action with respect to such shares
before the issuance thereof, then the date of delivery of such shares shall be
extended for the period necessary to complete such action.

                  (b) LISTING, QUALIFICATION, ETC. This Option shall be subject
to the requirement that if, at any time, counsel to the Company shall determine
that the listing, registration or qualification of the shares subject hereto
upon any securities exchange or under any state or federal law, or the consent
or approval of any governmental or regulatory body, is necessary as a condition
of, or in connection with, the issuance or purchase of shares hereunder, this
Option may not be exercised, in whole or in part, unless such listing,
registration, qualification, consent or approval shall have been effected or
obtained on conditions acceptable to the Board of Directors. Nothing herein
shall be deemed to require the Company to apply for or to obtain such listing,
registration or qualification.

         6. NONTRANSFERABILITY OF OPTION. Except as provided in paragraph (e) of
Section 3, this Option is personal and no rights granted hereunder may be
transferred, assigned, pledged or hypothecated in any way (whether by operation
of law or otherwise) nor shall any such rights be subject to execution,
attachment or similar process. Upon any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of this Option or of such rights contrary to
the provisions hereof, or upon the levy of any attachment or similar process
upon this Option or such rights, this Option and such rights shall, at the
election of the Company, become null and void.

         7. NO SPECIAL EMPLOYMENT RIGHTS. Nothing contained in the Plan or this
Agreement shall be construed or deemed by any person under any circumstances to
bind the Company top continue the employment of the Optionee for the period
within which this Option shall be exercised. However, during the period of the
Optionee's employment, the Optionee shall render diligently and faithfully the
services which are assigned to the Optionee from time to time by the Board of
Directors or by the executive officers of the Company and shall at no time take
any action which, directly or indirectly, would be inconsistent with the best
interests of the Company.

         8. RIGHTS AS A SHAREHOLDER. The Optionee shall have no rights as a
shareholder with respect to any shares which may be purchased by exercise of
this Option unless and until a certificate representing such shares is duly
issued and delivered to the Optionee. No adjustment shall be made for dividends
or other rights for which the record date is prior to the date such stock
certificate is issued.

         9. ADJUSTMENTS.

            (a) GENERAL. If, as a result of a merger, consolidation, sale of all
or substantially all of the assets of the Company, reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other distribution with respect to the outstanding shares of Common
Stock or other securities, the outstanding shares of Common Stock are increased
or decreased, or are exchanged for a different number or kind of shares or other
securities, or if additional shares or new or different shares or other
securities are distributed with respect to such shares of Common Stock or other
securities, an appropriate and proportionate adjustment may be made in (I) the
number and kind of shares or other securities subject to this Option and (ii)
the price for each share subject to this Option, without changing the aggregate
purchase price as to which this Option remains exercisable.

            (b) BOARD AUTHORITY TO MAKE ADJUSTMENTS. Adjustments under this
Section 9 will be made by the Board of Directors, whose determination as to what
adjustments, if any, will be made and the extent thereof will be final, binding
and conclusive. No fractional shares will be issued under this Option on account
of any such adjustments.

<PAGE>

            (c) LIMITS ON ADJUSTMENTS. No adjustment shall be made under this
Section 9 which would, within the meaning of any applicable provision of the
Code, constitute a modification, extension or renewal of this Option or a grant
of additional benefits to the Optionee.

         10. MERGERS, ETC. In the event of a merger or consolidation in which
the company is not the surviving corporation, or which results in the
acquisition of substantially all of the Company's outstanding Common Stock by a
single person, entity or group of person or entities acting in concert, or in
the event of a reorganization or liquidation of the Company, prior to the
Expiration Date or termination of this Option, the Optionee shall, with respect
to this Option or any unexercised portion hereof, be entitled to the rights and
benefits, and be subject to the limitations, set forth in Section 15 and 16 of
the Plan.

         11. WITHHOLDING TAXES. The Company's obligation to deliver shares upon
the exercise of this Option shall be subject to the Optionee's satisfaction of
all applicable federal, state and local income and employment tax withholding
requirements.

         12. LIMITATION ON DISPOSITION OF INCENTIVE STOCK OPTION SHARES:
RESTRICTIONS ON TRANSFER OF OPTION SHARES.

            (a) It is understood and intended that this Option shall qualify as
an "Incentive Stock Option" as defined in Section 422 of the Code. Accordingly,
the Optionee understands that in order to obtain the benefits of an Incentive
Stock Option under Section 421 of the Code, no sale or other disposition may be
made of any shares acquired upon exercise of this Option within one (1) year
after the day of transfer of such shares to him or her, nor within two (2) years
after the grant of the Option. If the Optionee intends to dispose, or does
dispose (whether by sale, exchange, gift, transfer or otherwise), of any such
shares within said periods, he or she will notify the Company in writing within
ten (10) days after such disposition.

            (b) Optionee agrees that, concurrently with the full or partial
exercise of this Option, Optionee shall execute such standard form of the
Company's stock restriction agreement as the Company may require on the exercise
date. Optionee acknowledges that the Company shall have no obligation to issue
shares of its Common Stock pursuant to an exercise of this Option until such
time as Optionee has signed the required form of stock restriction agreement.

         13. INVESTMENT REPRESENTATION: LEGEND  .

             (a) REPRESENTATIONS. The Optionee represents, warrants and
covenants that:

                 (1) Any shares purchased upon exercise of this Option shall be
acquired for the Optionees account for investment only and not with a view to,
or for sale in connection with, any distribution of the shares in violation of
the Securities Act of 1933 (the "Securities Act") or any rule or regulation
under the Securities Act.

                 (2) The Optionee has had such opportunity as he or she has
deemed adequate to obtain from representatives of the Company such information
as is necessary to permit Optionee to evaluate the merits and risks of his or
her investment in the Company.

                 (3) The Optionee is able to bear the economic risk of holding
shares acquired pursuant to the exercise of this Option for an indefinite
period.

                 (4) The Optionee understands that (A) the shares acquired
pursuant to the exercise of this Option will not be registered under the
Securities Act and are "restricted securities" within the meaning of Rule 144
under the Securities Act; (B) such shares cannot be sold, transferred or
otherwise disposed of unless they are subsequently registered under the
Securities Act or an exemption from registration is then available; (C) in any
event, the exemption from registration under Rule 144 will not be available for
at least two (2) years and even then will not be available unless a public
market then exists for the Common Stock, adequate information concerning the
Company is then available to the public and other

<PAGE>

conditions of Rule 144 art complied with; and (D) there is now no registration
statement on file with the Securities and Exchange Commission with respect to
any stock of the Company and the Company has no obligation or current intention
to register any shares acquired pursuant to the exercise of this Option under
the Securities Act.

         By making payment upon exercise of this Option, the Optionee shall be
deemed to have reaffirmed, as of the date of such payment, the representations
made in this Section 13.

                  (b) LEGEND ON STOCK CERTIFICATES. All stock certificates
representing shares of Common Stock issued to the Optionee upon exercise of this
Option shall have affixed thereto a legend substantially in the following form,
in addition to any other legends required by applicable state law:

                  "The shares of stock represented by this certificate have not
been registered under the Securities Act of 1933 and may not be transferred,
sold or otherwise disposed of in the absence of an effective registration
statement with respect to the shares evidenced by this certificate, filed and
made effective under the Securities Act of 1933, or an opinion of counsel
satisfactory to the Company to the effect that registration under such Act is
not required."

         14.      MISCELLANEOUS.

                  (a) Except as provided herein, this Option may not be amended
or otherwise modified unless evidenced in writing and signed by the Company and
the Optionee.

                  (b) All notices under this Option shall be mailed or delivered
by hand to the parties at their respective addresses set forth beneath their
names below or at such other address as may be designated in writing by either
of the partied to one another.

                  (c) This Option shall be governed by and construed in
accordance with the laws of the State of Delaware.
